1. Hydraulic metal baler
The closed-lid two-way extrusion hydraulic metal baler is now the most common baler used in China. It squeezes light and thin materials into lumps according to the hydraulic squeezing pressure in two different directions on the same horizontal plane to increase its density. It is suitable for the recycling of scrap iron and steel in the society and the light and thin materials in the processing industry. The structure is simple, the cover lock pin is widely used to replace the vertical extrusion mechanism, the opening of the material box is large, the feeding is convenient, and it is widely applicable to the light and thin steel scrap produced and processed. There are two kinds of manual and semi-automatic, nearly 40 models with different specifications.
There are squeeze, push, turn, etc. The characteristics of the packer are:
a. Small investment, the cost of each packer is between 100,000 and 1 million yuan;
b. The total area is small, the facility itself occupies about 10-20m2, and the total storage turnover area is about 100m2;
c. The actual operation is simple and easy to learn, and it can be filled manually or mechanically. It can produce and process scrap steel with a thickness of less than 2mm, such as light and thin steel scraps such as buckets, iron, color plates, light steel doors and windows.
(1) Structural features
The mechanical system, electrical system, and hydraulic system of the two-way squeeze hydraulic golden packer are combined. The automatic control system for each action is composed of hydraulic oil tank, motor oil pump group, valve station and piping system, etc., used for control and drive Each hydraulic cylinder works, so each action function of the whole process of packaging is carried out to pre-press the material and cause the material box to be closed and compressed. The door cover is hinged on the pin sleeves on the rear side of the left and right side frames by the pin, and the cylinder is in the door cover. Do 90 around the axis under the action. Flip motion, complete merging and opening actions to perform primary compression on the material. The door cover cylinder is connected with the door cover by a slider, the slider lock and the spring are used to pull out the slider lock and the mortise lock action compresses the materials in the compression chamber to form a strip, which is convenient for final packaging Side pressure, the oil cylinder is installed in the side pressure cylinder support, and the tail is supported by the auxiliary support to adjust the axis of the oil cylinder and the side of the base. The Xu head and the piston rod are fixed with a midge bolt, and the front part is equipped with wear-resistant lining The main pressure cylinder is installed in the main pressure cylinder support, and the main pressure cylinder is installed in the main pressure cylinder support. The auxiliary support supports the tail to adjust the cylinder axis to be parallel to the base. The main pressure head and the piston rod are fixed by lifting bolts, and the front part is equipped with a liner, which performs final compression on the items in the material box to complete the turning and resetting actions. The turning shaft and the bearing seat are installed on the side frame. The package board is also treated with wear resistance and installed in the box, which is conducive to the push of the package turning cylinder to rotate the turning shaft. The left and right side frames, front frame, base, door cover, main pressure head, side pressure head and its turning plate The archway of the composition material box (compression chamber) is welded to the rear of the left and right side frames, and the door cover cylinder is installed
Welded on the front part of the base, there is a lock sleeve on the top of the silver-purple door cover to prevent the door cover from floating.
The main function of each component:
Main pressure cylinder: used for final compression. The front flange is installed on the main cylinder support of the side frame with the front flange, and the piston rod and the pressure head are connected with screws;
Lateral pressure cylinder: used for secondary compression to make the raw material in the compressed slaughter preliminarily formed and installed on the lower side of the archway. The two half-pins are hinged in the support holes at the rear of the left and right side frames of the fuselage. The piston rod and the pressure head are used Screw connection
Door cover cylinder: through the forward and backward of the piston rod to complete the opening, closing and locking action of the door benefit. Two pins are hinged to the door cover cylinder support of the archway of the fuselage, and the piston rod and the sliding block on the door cover are pin shafts. connection;
Turnover cylinder: used to drive the turnover to complete the turnover action. It is fixed on the outside of the front frame and hinged with the turnover axis according to the pin shaft;
The above cylinders are single-piston rod double-acting oil cylinders. The cylinder body is equipped with a piston. The piston is equipped with a wear-resistant two-way sealing ring, so that two large and small oil chambers are formed in the oil cylinder. When the high-pressure oil acts on the sealing ring, the sealing ring The two wings are closely attached to the piston and the cylinder wall to ensure that the two oil chambers cannot communicate with each other. The cylinder port is also provided with a guide sleeve for supporting, guiding and sealing the piston rod.
3. Safe operation and maintenance
①The operating procedures and maintenance rules and regulations should be formulated according to the characteristics of commonly used balers, woodworking workshops, materials to be packaged, staff conditions, and work shifts.
② Operators can only operate after learning and training, mastering the equipment structure, performance, operating procedures and maintenance rules and regulations.
③Before the work of the facility, check whether there are any materials in the packaged materials that may affect the safety of the equipment and the safety of the staff, and the facility can be opened to work if it is correct.
④ The hydraulic oil in the fuel tank must be filtered through strict requirements and kept in sufficient quantity. People should be added first when checking for defects frequently to prevent the gasoline pump from being emptied.
⑤Every lubrication point should be checked daily, and lubrication should be done according to the condition of the facility.
⑥ The hydraulic oil should be cleaned or replaced once every six months.
⑦Oil leakage or other abnormal phenomena occur, stop immediately, analyze the root cause to find the mechanical failure, and prohibit operation with diseases.
⑧ The overhaul and adjustment of facilities must be carried out by trained and experienced staff.
⑨It is forbidden to carry out maintenance during the whole process of packing. All parts of the body are forbidden to touch the moving parts of the equipment, and it is forbidden to press the material of the bin with hands or feet.
⑩Clean up the dirt in the material bin after work every day, maintain the facilities, and keep the equipment clean and tidy. The place should be cleaned and free of debris.
