[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, the utility model discloses a waste chip compression device, which includes a box body 1. The box body 1 is tilted and a plurality of supports are provided at the bottom of the box body 1.

[0034] A rectangular compression chamber is provided inside the box body 1, in which a first pressing block 4 and a second pressing block 5 are slidingly provided. The shapes and sizes of the first pressing block 4 and the second pressing block 5 are adapted to the compression chamber, and the first pressing block 4 is located obliquely above the second pressing block 5.

[0035] Hydraulic cylinders are mounted on the outer walls of the upper and lower ends of the housing 1. Their piston rods slide through the sidewalls at the upper and lower ends of the housing 1 and connect to the first and second pressure blocks 4 and 5, respectively. These hydraulic cylinders drive the first and second pressure blocks 4 and 5 to slide within the compression chamber. Pores or gaps exist between the first and second pressure blocks 4, 5, and the inner walls of the compression chamber to prevent over-sealing, which could lead to an increase in internal pressure during the sliding of the first and second pressure blocks 4, 5. Accordingly, through-holes are provided on both the upper and lower ends of the housing 1 to prevent internal sealing.

[0036] A material port 2 is provided at the top of the box body 1 near the higher end, and a hopper 3 is provided on the material port 2. Waste chips enter the box body 1 through the hopper 3 and the material port 2.

[0037] A pusher is installed on the lower side of the box body 1 near the material inlet 2. The distance between the pusher and the material inlet 2 is greater than the thickness of the first pressing block 4. A discharge device is installed at the bottom of the box body 1 below the pusher. The sidewalls of the box body 1 are thickened away from the higher end of the box body 1, and waste chips are mainly compressed in this area.

[0038] The pushing device includes a pushing plate 14 arranged on the inner wall of the top of the box body 1, and a plate groove for accommodating the pushing plate 14 is correspondingly provided on the inner wall of the box body 1. A driving unit is provided in the side wall of the box body 1 on the side of the pushing plate 14, and the driving unit pushes the pushing plate 14 to slide in a direction perpendicular to the sliding trajectory of the first pressing block 4 and the second pressing block 5.

[0039] The drive unit includes a drive rod 9 that is rotatably arranged in the side wall of the box body 1. The drive rod 9 is arranged parallel to the push plate 14. One end of the drive rod 9 is provided with a motor 11 that is transmission-connected thereto. Three supports 13 arranged in a straight track are evenly spaced on the side wall of the push plate 14 near the drive rod 9. The arrangement track of the three supports 13 is parallel to the axial direction of the drive rod 9. Two push rods 12 are hinged on the supports 13 respectively. The angle between the two push rods 12 is less than ninety degrees. The ends of the two push rods 12 away from the supports 13 are hinged with drive blocks 10. The two drive blocks 10 are respectively threadedly engaged with the drive rod 9. Corresponding screw holes are provided on the drive blocks 10, and corresponding threads are provided on the drive rod 9. In addition, the directions of the threads in the sliding tracks of the two drive blocks 10 on the drive rod 9 are opposite, so that when the drive rod 9 rotates, the two drive blocks 10 move synchronously in opposite directions. A sliding groove corresponding to the driving block 10 is provided in the side wall of the box body 1 at the driving rod 9. The sliding groove is arranged parallel to the driving rod 9. The sliding groove serves as a sliding guide for the driving block 10, allowing the driving block 10 to slide axially along the driving rod 9.

[0040] The operation of the motor 11 causes the drive rod 9 to rotate forward. The drive rod 9 is threadedly engaged with the multiple drive blocks 10, causing the drive blocks 10 at the ends of the two push rods 12 hinged on the same support 13 to slide toward each other. The angle between the two push rods 12 on the same support 13 is reduced, and the push plate 14 is pushed into the compression chamber. The operation of the motor 11 causes the drive rod 9 to rotate backward. The drive rod 9 is threadedly engaged with the multiple drive blocks 10, causing the drive blocks 10 at the ends of the two push rods 12 hinged on the same support 13 to slide away from each other. The angle between the two push rods 12 on the same support 13 is increased, and the push plate 14 is pushed into the plate groove of the side wall of the box body 1.

[0041] The discharge device includes an opening provided on the side wall of the box body 1 at the bottom of the compression chamber. The width of the opening is adapted to the width of the compression chamber, and the length of the opening is not less than the length of the waste chips after being compressed into blocks. A baffle 6 is slidably provided in the opening. A slot for the baffle 6 to slide into is provided in the side wall of the box body 1 on the side of the opening near the higher end of the box body 1. A cylinder 8 for driving the baffle 6 to slide is provided on the outer wall of the box body 1 outside the slot. The cylinder 8 drives the baffle 6 to slide into the opening to seal the opening, and the cylinder 8 drives the baffle 6 to slide into the slot to open the opening. A plurality of pins 7 are provided at the lower end of the baffle 6. The pins 7 are arranged parallel to the sliding direction of the baffle 6. The ends of the pins 7 away from the baffle 6 have a truncated cone-shaped guide portion. The side wall of the opening away from the slot is provided with a plurality of slots corresponding to the positions, shapes and sizes of the plurality of pins 7.

[0042] When the waste chips are compressed, the cylinder 8 drives the baffle 6 to slide into the opening to close the opening. The second pressing block 5 is in contact with the lower end of the box body 1, and the first pressing block 4 is on the side of the material port 2 close to the higher end of the box body 1. The waste chips enter the compression chamber between the first pressing block 4 and the second pressing block 5 from the hopper 3 and the material port 2. Since the box body 1 is tilted, the waste chips can be close to the filling state, and then the first pressing block 4 slides toward the lower end of the box body 1 to gradually compress the waste chips. After the first pressing block 4 and the second pressing block 5 have completed the compression of the waste chips, the first pressing block 4 and the second pressing block 5 are in contact with the lower end of the box body 1. The two pressure blocks 5 slide synchronously toward the higher end of the box body 1, and place the waste block between the discharge device and the pushing device. The cylinder 8 drives the baffle 6 to slide into the slot, and the driving unit drives the pushing plate 14 to slide toward the compression chamber, pushing the waste block into the opening so that it is automatically discharged from the box body 1. Then the cylinder 8 drives the baffle 6 to slide into the opening to close it, and the driving unit drives the pushing plate 14 to slide into the plate slot. The first pressure block 4 slides to the material port 2 close to the higher end side of the box body 1 to achieve reset, and the second pressure block 5 slides to the lower end of the box body 1 to achieve reset, and the next waste compression can be carried out.

[0043] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
