Description

Technical Field

[0001] This utility model relates to the field of plastic crushing technology, specifically to a waste plastic crushing device. Background Technology

[0002] Waste plastic crushing equipment is a device used to centrally crush waste plastics.

[0003] Based on the above, the inventors have discovered that: Currently, there are many waste plastic crushing devices on the market. However, in general waste plastic crushing devices, workers collect the waste plastics into the crusher. Since plastics are lightweight, they are not easy to quickly enter the crusher. Currently, workers usually use a plunger to press the waste plastics in the crusher's feed column one by one. However, the pressing efficiency is low, and the plunger is easily moved to the vicinity of the crusher's blades, causing jamming between the crusher and the plunger. This seriously affects the crushing effect of the device on the plastics. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a waste plastic crushing device with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a waste plastic crushing device, including a crusher, a connecting plate fixed to the top of the crusher, a feeding column at the top of the connecting plate, a pressing mechanism on the inner wall of the feeding column, and a protective mechanism on the inner wall of the feeding column.

[0006] The pressing mechanism includes:

[0007] A pressure plate has its outer wall sliding against the inner wall of the feed column. A connecting column is fixed to the top of the pressure plate, and a rack is fixed to one side of the connecting column. The rack is located on one side of the feed column, and a drive motor is fixed to one side of the feed column. A gear is coaxially connected to one end of the drive motor, and the outer wall of the gear drives the outer wall of the rack.

[0008] As a preferred technical solution of this utility model, a U-shaped plate is fixed on one side of the feed column, and a sliding groove is provided on both sides of the inner wall of the U-shaped plate. A sliding plate is fixed on the inner wall of both sliding grooves, and one side of both sliding plates is fixed to the outer wall of the rack.

[0009] As a preferred embodiment of this utility model, two horizontal columns are fixed at the top of the pressure plate, and two limiting plates slide on the outer walls of the two horizontal columns, with both limiting plates located at the top of the pressure plate.

[0010] As a preferred embodiment of this utility model, the protective mechanism includes:

[0011] A trapezoidal column is disposed on the inner wall of the feed column and at the top of the connecting plate. The vertical cross-sectional area of ​​the inner wall of the trapezoidal column is smaller than the vertical cross-sectional area of ​​the outer wall of the pressure plate.

[0012] As a preferred embodiment of this utility model, four vertical rods are fixed at the top of the trapezoidal column, and the four vertical rods are all located inside the feed column, with the outer walls of the four vertical rods sliding against the inner wall of the pressure plate.

[0013] As a preferred embodiment of this utility model, the bottom end of the trapezoidal column is fixed with two locking blocks, and the top end of the connecting plate is provided with two locking slots, the inner walls of the two locking slots being matched with the outer walls of the locking blocks.

[0014] As a preferred embodiment of this utility model, each of the two limiting plates has two recessed blocks at its top, and the bottom of each of the four recessed blocks is matched with the inner wall of the horizontal column.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this solution, the limiting plate slides on the outer wall of the horizontal column until it reaches the designated position. The bottom end of the concave block engages with the inner wall of the horizontal column, and the concave block matches the outer wall of the limiting plate. This allows the pressure plate to better squeeze and drop the plastic inside the feed column. The drive motor rotates the gear, which in turn drives the rack and pinion transmission, causing the rack to move up and down on one side of the feed column. Simultaneously, the sliding plate fixed to the feed column slides on the inner wall of the U-shaped plate, thus causing the pressure plate to move up and down on the inner wall of the feed column. This squeezes the waste plastic placed above the crusher, reducing the burden on workers who manually squeeze the waste plastic using the insert column, increasing the crushing rate of the waste plastic, and facilitating the normal operation of the device.

[0017] 2. In this design, a trapezoidal column is installed at the top of the connecting plate, and a locking block fixed at the bottom of the trapezoidal column is inserted into the slot. This engages the inner wall of the feed column with the outer wall of the trapezoidal column. The pressure plate slides on the inner wall of the feed column, allowing the inner wall of the pressure plate to slide against the outer wall of the vertical rod. The pressure plate is positioned at the top of the trapezoidal column, which facilitates better driving of the pressure plate to slide on the inner wall of the feed column. This prevents the pressure plate from accidentally entering the crusher and causing it to jam between the pressure plate and the blades on the crusher. This effectively prevents the pressure plate from falling into the crusher, thus facilitating better crushing and processing of waste plastics and improving the practicality of the device.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-4 As shown, the present invention provides a waste plastic crushing device, including a crusher 1, a connecting plate 2 fixed at the top of the crusher 1, a feeding column 3 at the top of the connecting plate 2, a pressing mechanism 4 on the inner wall of the feeding column 3, and a protective mechanism 5 on the inner wall of the feeding column 3.

[0026] The pressing mechanism 4 includes:

[0027] The pressure plate 41 has an outer wall that slides against the inner wall of the feed column 3. A connecting column 42 is fixed to the top of the pressure plate 41. A rack 43 is fixed to one side of the connecting column 42. The rack 43 is located on one side of the feed column 3. A drive motor 44 is fixed to one side of the feed column 3. A gear 45 is coaxially connected to one end of the drive motor 44. The outer wall of the gear 45 drives the outer wall of the rack 43.

[0028] As attached Figure 3As shown, a U-shaped plate 6 is fixed on one side of the feed column 3. Slide grooves 7 are provided on both sides of the inner wall of the U-shaped plate 6. Slide plates 8 are fixed on the inner walls of the two slide grooves 7. One side of the two slide plates 8 is fixed to the outer wall of the rack 43, so that the rack 43 can be stably installed on one side of the feed column 3.

[0029] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, two horizontal columns 9 are fixed to the top of the pressure plate 41. Two limiting plates 10 slide on the outer wall of the two horizontal columns 9. Both limiting plates 10 are set at the top of the pressure plate 41. Two concave blocks 11 are provided at the top of the two limiting plates 10. The bottom ends of the four concave blocks 11 are matched with the inner wall of the horizontal columns 9 to increase the contact area between the pressure plate 41 and the waste plastic. At the same time, it is convenient to reset the limiting plates 10 after the plastic is crushed so that the crusher 1 can be reloaded. This makes it easier for the pressure plate 41 to squeeze and drop the plastic inside the feed column 3.

[0030] As shown in Appendix 1 and Figure 2 As shown, the protective mechanism 5 includes:

[0031] A trapezoidal column 51 is installed on the inner wall of the feed column 3 and at the top of the connecting plate 2. The vertical cross-sectional area of ​​the inner wall of the trapezoidal column 51 is smaller than that of the outer wall of the pressure plate 41. Four vertical rods 52 are fixed at the top of the trapezoidal column 51. All four vertical rods 52 are installed inside the feed column 3. The outer walls of the four vertical rods 52 slide against the inner wall of the pressure plate 41. Two locking blocks 53 are fixed at the bottom of the trapezoidal column 51. Two locking grooves 54 are opened at the top of the connecting plate 2. The inner walls of the two locking grooves 54 match the outer walls of the locking blocks 53 to prevent the pressure plate 41 from accidentally entering the crusher 1 and causing the pressure plate 41 to jam with the blades on the crusher 1. This effectively prevents the pressure plate 41 from falling into the crusher 1, thus facilitating better crushing of waste plastics by the device.

[0032] Working principle: In use, the trapezoidal column 51 is installed on the top of the connecting plate 2, and the locking block 53 fixed at the bottom of the trapezoidal column 51 is inserted into the slot 54. The inner wall of the feed column 3 is engaged with the outer wall of the trapezoidal column 51. The limiting plate 10 is slid on the outer wall of the horizontal column 9 until it is moved to the designated position on the horizontal column 9. The bottom end of the concave block 11 is engaged with the inner wall of the horizontal column 9, and the concave block 11 is matched with the outer wall of the limiting plate 10, thus limiting the movement of the feed column 3. The position plate 10 is securely installed on the outer wall of the horizontal column 9. The control drive motor 44 drives the gear 45 to rotate, which in turn drives the rack 43 to move up and down on one side of the feed column 3. At the same time, the slide plate 8, which is fixed to the feed column 3, slides on the inner wall of the groove 7 opened on the inner wall of the U-shaped plate 6, thereby causing the pressure plate 41 to move up and down on the inner wall of the feed column 3. This squeezes the waste plastic placed above the crusher 1, accelerating its rapid entry into the crusher 1 for crushing.
