Description

Technical Field

[0001] The utility model relates to the technical field of plastic shell processing, in particular to a waste material recovery device for plastic shell processing. Background Art

[0002] With the development of industry, plastics have been widely used. During the manufacturing process, plastics are molten liquids. Therefore, they can be melted by heating, made to flow by applying pressure, and solidified by cooling to form various shapes. The processing of plastics produces a lot of waste. Plastic waste can be recycled, so it is necessary to recycle the waste generated during the plastic processing process.

[0003] The patent document with application number CN202020720577.0 discloses a waste recycling device for plastic processing. When the device is used, plastic waste is put into the box through the feed port, and the motor is started by the controller. The transmission shaft of the motor drives the rotating shaft and the structure connected to the rotating shaft to rotate, and the crushing roller rotates to crush the added plastic waste. The crushed waste falls to the top of the filter plate, and the vibration motor is started by the controller. The vibration motor drives the filter plate to vibrate, and the water in the waste passes through the filter plate and falls into the funnel and flows out from the outlet pipe. The crushed plastic enters the press box through the discharge port. After the debris in the press box accumulates to a certain amount The controller activates the first electric telescopic rod to perform telescopic movement, which pushes the baffle downward to close the discharge port and prevent the plastic debris from flowing out. The controller activates the second electric telescopic rod to perform telescopic movement, which pushes the pressure plate downward into the press box to squeeze the debris in the press box into blocks. The second electric telescopic rod contracts to lift the pressure plate. The controller activates the third electric telescopic rod to perform telescopic movement, which pushes the push plate and the plastic block on top of the push plate upward. When the push plate is about to move to the top of the press box, the second slider contacts the top of the second chute, causing the push plate to tilt and the plastic block to slide off the surface of the push plate. The device can squeeze plastic debris and filter out water in the plastic debris (the water in plastic waste is generally left when the plastic waste is cleaned). It can also squeeze the plastic debris so that the plastic debris is squeezed into blocks for easy storage. However, the device lacks a device for magnetic separation of plastic debris and cannot effectively remove iron impurities in the plastic debris.

[0004] The patent document with application number CN202123387185.0 discloses a waste recycling device for plastic processing. When in use, the drive motor is started, and the output end of the drive motor drives the rotating rod on the right to rotate, the rotating rod on the right drives the gear on the right to rotate, the gear on the right drives the gear on the left to rotate, and the gear on the left drives the rotating rod on the left to rotate, and the rotating rod drives the crushing roller to rotate, and the crushing roller crushes the plastic. The crushed plastic falls to the upper surface of the filter plate through two sets of guide plates, and the water carried in the plastic falls to the bottom of the box through the filter plate and is then discharged through the drain pipe. The first push rod is started, and the piston rod of the first push rod drives the push plate to move to the left, and the push plate squeezes the crushed plastic to the left, so that the push plate, the box and the baffle cooperate with each other to squeeze the plastic into blocks. The second push rod is started, and the piston rod of the second push rod drives the joint plate to move upward, and the joint plate drives the baffle to move upward. The piston rod of the first push rod continues to move to the left to push the squeezed plastic out of the box. This recycling device optimizes the extrusion mechanism for squeezing plastic debris, which is located within the box, resulting in a more compact structure. However, the recycling device also lacks a magnetic separation device for the plastic debris, making it unable to remove iron impurities from the plastic debris. Furthermore, the plastic debris can only be discharged from a single side of the box, resulting in low plastic debris processing efficiency. Utility Model Content

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Example 1: Reference Figure 1-Figure 4 As shown, the waste recycling device for processing plastic shells 1 includes a shell 1, the upper end of the shell 1 is fixedly connected to a hopper 2, and a crushing device is provided in the shell 1 below the hopper 2.

[0043] The comminution device includes two crushing rollers 10 rotatably arranged in a shell 1 , and the crushing rollers 10 are driven by a motor 3 fixed outside the shell 1 .

[0044] After being cleaned, the plastic waste is put into the housing 1 from the hopper 2. The motor 3 drives the crushing roller 10 to rotate. The rotating crushing roller 10 can crush the plastic waste into plastic debris.

[0045] A material distributor is fixed in the housing 1 below the pulverizing device. The material distributor comprises two inclined plates 11 , the opposite ends of the two inclined plates 11 are fixedly connected and tilted upward, and an electromagnet 12 is fixed on the underside of each inclined plate 11 .

[0046] The front and rear ends of the inclined plate 11 are fixedly connected to the front and rear side walls of the housing 1 respectively.

[0047] The plastic debris discharged from between the two crushing rollers 10 can be divided into the left and right directions within the housing 1 by the two inclined plates 11. As the plastic debris slides down the inclined plates 11, the electromagnet 12 can absorb the iron impurities in the plastic debris, thereby retaining the iron impurities in the plastic debris on the inclined plates 11.

[0048] The left and right sidewalls of the housing 1 below the distributor are each provided with a groove 13. A guide plate 6 is rotatably connected within the groove 13, extending through the groove 13 on one side. Specifically, a rotating shaft is fixed within the groove 13, rotatably connected to the guide plate 6. The front and rear ends of the guide plate 6 respectively slide in contact with the front and rear sidewalls of the housing 1. The guide plate 6 is tilted downward toward the center of the housing 1. One end of the guide plate 6, located outside the housing 1, is movably connected to the housing 1 via an external telescoping assembly.

[0049] The external telescopic assembly includes an external double-end telescopic rod 9, an upper ear plate 7 is fixed to one end of the guide plate 6 outside the shell 1, and a lower ear plate 8 is fixed to the shell 1. One end of the external double-end telescopic rod 9 is rotatably connected to the upper ear plate 7, and the other end of the external double-end telescopic rod 9 is rotatably connected to the lower ear plate 8.

[0050] The outer double-end telescopic rod 9 is activated to retract the outer double-end telescopic rod 9 , and one end of the guide plate 6 in the housing 1 can rotate upward in the housing 1 .

[0051] When one end of the guide plate 6 in the housing 1 contacts the upper end of the support plate 14 on one side, the guide plate 6 blocks the groove 13 on one side. When the guide plate 6 rotates and contacts the lower end of the inclined plate 11 on one side, the height of the one end of the guide plate 6 outside the housing 1 is lower than the height of the one end of the guide plate 6 inside the housing 1, and there is a gap between the upper end of the guide plate 6 and the upper wall of the groove 13.

[0052] A support plate 14 is fixed within the housing 1 below the guide plate 6. The front and rear ends of the support plate 14 are respectively fixedly connected to the front and rear side walls of the housing 1. One end of the guide plate 6 within the housing 1 contacts the upper end of the support plate 14. A filter plate 16 is fixed within the housing 1 below the support plate 14. Two push plates 19 are slidably disposed between the two support plates 14. The front and rear ends of the push plates 19 respectively slide in contact with the front and rear side walls of the housing 1. The lower end of the push plate 19 slides in contact with the upper end of the filter plate 16. After the push plate 19 moves below the support plate 14, the upper end of the push plate 19 slides in contact with the lower end of the support plate 14.

[0053] The two push plates 19 are connected by an inner telescopic assembly.

[0054] The internal telescopic assembly includes a fixed block 17 fixed to the upper end of the filter plate 16, the fixed block 17 is located between the two push plates 19, and a plurality of internal double-end telescopic rods 18 are fixed in the fixed block 17. The internal double-end telescopic rods 18 are arranged horizontally, and the two ends of the internal double-end telescopic rods 18 are respectively fixedly connected to the two push plates 19.

[0055] When the inner double-ended telescopic rod 18 is extended, the two push plates 19 move away from each other and can squeeze the plastic debris on the filter plate 16 .

[0056] Slots are provided on the left and right side walls of the housing 1 between the filter plate 16 and the support plate 14 , the slots corresponding to the push plates 19 , and blocking components are provided on both the left and right sides of the housing 1 to block the slots.

[0057] The blocking assembly includes a baffle 15, which is in sliding contact with the shell 1 and blocks the slot on one side of the baffle 15. Slide rails 4 are fixed on the shell 1 on both sides of the front and rear of the baffle 15. The baffle 15 is slidably arranged in the slide rails 4. A cylinder 5 is fixed on the shell 1 below the baffle 15, and the telescopic end of the cylinder 5 is fixedly connected to the baffle 15.

[0058] During operation, the plastic waste is cleaned and then put into the shell 1 from the hopper 2. The motor 3 drives the crushing roller 10 to rotate. The rotating crushing roller 10 can crush the plastic waste into plastic debris. The plastic debris discharged from between the two crushing rollers 10 can be distributed to the left and right sides of the shell 1 by the two inclined plates 11. In the process of the plastic debris sliding on the inclined plate 11, the electromagnet 12 can adsorb the iron impurities in the plastic debris, thereby causing the iron impurities in the plastic debris to remain on the inclined plate 11. The plastic debris sliding down from the inclined plate 11 falls onto the filter plate 16 under the guidance of the guide plate 6. At this time, one end of the guide plate 6 in the shell 1 contacts the support plate 14 on one side thereof, and the guide plate 6 blocks the groove 13 on one side thereof, which can prevent the plastic debris from being discharged from the groove 13 to the outside of the shell 1.

[0059] The water in the plastic debris flows into the lower end of the housing 1 through the filter plate 16. The lower end of the housing 1 is open, and the water can be discharged through the lower end of the housing 1.

[0060] After the plastic waste is crushed, the inner double-ended telescopic rod 18 is activated, causing the push plate 19 to move toward the baffle 15 on its side. The push plate 19 and the baffle 15 work together to squeeze the plastic debris between the push plate 19 and the baffle 15, thus squeezing the plastic debris into blocks. As the plastic debris is squeezed, the water in the plastic debris is discharged again and flows down through the filter plate 16.

[0061] After the plastic debris is squeezed, the cylinder 5 is started, which drives the baffle 15 downward and opens the slot, and then continues to move the push plate 19 toward the baffle 15, thereby pushing the block-shaped plastic debris out of the slot to the outside of the housing 1.

[0062] When cleaning ferrous impurities from the swash plate 11 is necessary, the outer double-ended telescopic rod 9 is activated and retracted, causing one end of the guide plate 6 inside the housing 1 to rotate upward within the housing 1. When the guide plate 6 contacts the lower end of the swash plate 11 on one side, the height of the guide plate 6 outside the housing 1 is lower than that of the guide plate 6 inside the housing 1, and a gap exists between the upper end of the guide plate 6 and the upper wall of the groove 13. By deactivating the electromagnet 12, ferrous impurities on the swash plate 11 are guided through the gap between the upper end of the guide plate 6 and the upper wall of the groove 13 and discharged outside the housing 1.

[0063] Example 2: Based on Example 1, refer to Figure 3 As shown, an upper plate 20 is fixed in the shell 1 above the push plate 19, and the front and rear ends of the upper plate 20 are fixedly connected to the front and rear side walls of the shell 1. The upper end of the upper plate 20 is processed with two guide inclined surfaces arranged symmetrically on the left and right, and the upper end of the push plate 19 is in sliding contact with the lower end of the upper plate 20.

[0064] When crushing plastic waste, the push plate 19 is located between the upper plate 20 and the filter plate 16. The upper plate 20 blocks the plastic debris from entering the filter plate 16 between the two push plates 19. The guiding slope on the upper plate 20 prevents the plastic debris from remaining on the upper plate 20.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
