Description

Technical Field

[0001] The invention belongs to the technical field of plastic particle processing, and in particular relates to a plastic particle production and crushing device. Background Art

[0002] In daily life, plastic products are disposable items that people often use. They have been widely used in the fields of food, medicine, and chemical industry, among which food packaging accounts for the largest proportion. Since plastics are difficult to degrade, if used plastic products are directly landfilled or incinerated, it will cause serious environmental pollution and a lot of waste. Therefore, the technology and equipment for the recycling of waste plastics and plastic lunch boxes came into being. After the waste plastic products are crushed, cleaned and dried for recycling, they are processed into uniform recycled plastic particles through melting and extrusion equipment, so that the recycled plastics can be put into production again, reducing environmental pollution and waste.

[0003] Traditional plastic crushing equipment (such as pulverizers, etc.) drives the cutter shaft to rotate through a motor, so that when the waste plastic is put into the crushing bin, the waste plastic is cut by the cutter. However, since plastic products usually have a certain degree of ductility, if the plastic products are not compressed in batches before processing, the subsequent crushing efficiency will be affected. Most of the existing plastic crushing equipment does not have a compression function, and special equipment is required to compress plastic products, which will increase production costs and is not conducive to production.

When the pressing plate moves to be flush with the connecting rod again, the electromagnet will be energized to work, and the electromagnetic force of the electromagnet causes the first plug to retract into the installation hole. At this time, the pressing plate can drive the adjustment plate to move upward through the connecting unit. When the positioning plug is detached from the first plug hole, the connecting unit will automatically connect the adjustment plate to the pressing plate again until the pressing plate returns to its initial position, completing a processing process.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0016] like Figure 1-Figure 7 As shown, a plastic granule production and crushing device provided by an embodiment of the present invention includes a frame 1, on which a crushing module 2 is arranged; and further includes: The storage module 3 comprises a bottom plate 31 arranged on the top of the crushing module 2, a material discharge chute 311 is provided in the middle of the bottom plate 31, two sealing plates 33 are symmetrically arranged at the bottom of the bottom plate 31, the sealing plates 33 are slidably mounted at the bottom of the bottom plate 31, and the crushing module 2 is also provided with an adjustment unit 8 for driving the two sealing plates 33 to move toward or in the opposite direction at the same time, two fixed side plates 32 are symmetrically arranged on the bottom plate 31, two movable side plates 35 are symmetrically arranged between the two fixed side plates 32, and the movable side plates 35 are slidably mounted on the bottom plate 31, and the outer side of the bottom plate 31 is also connected to the bottom plate 31 through a first return spring 34; The extrusion module 5 includes a pressing plate 51. The frame 1 is provided with a lifting unit 4 for driving the pressing plate 51 to move up and down in the vertical direction. Two adjustment plates 52 are symmetrically arranged on both sides of the pressing plate 51. The adjustment plates 52 include a connecting rod 522. The pressing plate 51 is also provided with a connecting unit 7 for adjusting the connection state between the pressing plate 51 and the connecting rod 522. An inclined push plate 521 is arranged on the side of the connecting rod 522 away from the pressing plate 51. The bottom end of the inclined push plate 521 is connected to an outer limit plate 523. When the pressing plate 51 is at the upper limit position, the outer limit plate 523 abuts against the outer wall of the movable side plate 35. The limiting module 6 is provided at the top of each of the fixed side panels 32, and the limiting module 6 includes a limiting platform 61 installed at the middle position of the top of the fixed side panel 32, and two first plug holes 612 are symmetrically provided at both ends of the limiting platform 61, and two positioning plugs 65 matching the first plug holes 612 are provided at both ends of each of the connecting rods 522, and two mounting holes 611 are symmetrically provided inside the limiting platform 61, and a first plug hole 612 is slidably installed in the mounting hole 611. An insert block 62, one end of the first insert block 62 located in the mounting hole 611 is connected to the inside of the mounting hole 611 through a second return spring 63. When not subject to external force, one end of the first insert block 62 will extend into the first plug hole 612. An electromagnet 64 is also provided in the mounting hole 611. The bottom of the positioning block 65 is provided with a first inclined surface 652 matching the first insert block 62, and the side wall of the positioning block 65 is also provided with a plug groove 651 matching the first insert block 62.

[0017] In the embodiment of the present invention, when the positioning plug 65 is inserted into the first plug hole 612 and the first plug 62 is inserted into the plug slot 651, the connection unit 7 disconnects the adjustment plate 52 from the pressure plate 51; when the first plug 62 is disengaged from the plug slot 651 and the positioning plug 65 is disengaged from the first plug hole 612, the connection unit 7 connects the adjustment plate 52 to the pressure plate 51. In the initial state, the pressure plate 51 is located at the upper limit position, at which time the two movable side plates 35 are both located at the outermost side, and the operator can pour the plastic products to be processed into the storage module 3 from the upper side. Then, the lifting unit 4 is started, and the pressing plate 51 is driven to move downward by the lifting unit 4, and the extrusion module 5 can drive the two adjustment plates 52 to move downward synchronously. In this process, the outer limit plate 523 first contacts the outer wall of the movable side plate 35, and then the inclined push plate 521 contacts the movable side plate 35. Finally, the connecting rod 522 contacts the top of the movable side plate 35, and the movable side plate 35 can be pushed to slide inward by the inclined push plate 521. The plastic products in the storage module 3 are squeezed by the mutual cooperation of the two movable side plates 35. When the connecting rod 522 contacts the top of the movable side plate 35, the positioning plug 65 is inserted into the first plug hole 612. In this process, the first inclined surface 652 first contacts the first plug block 62 and pushes the first plug block 62 into the mounting hole 611 (the electromagnet 64 is not energized during this process). As the positioning plug 65 continues to move downward, the elastic force of the second return spring 63 causes the first plug 62 to extend from the mounting hole 611 and insert into the plug slot 651, and the adjustment plate 52 is fixed as a whole. At the same time, the connection unit 7 disconnects the adjustment plate 52 from the pressure plate 51, and the pressure plate 51 continues to move downward alone, thereby squeezing the plastic product between the two movable side plates 35. When the squeezing reaches a specified degree, the adjustment unit 8 controls the two sealing plates 33 to move in opposite directions at the same time, so that the compressed plastic product can fall from the discharge chute 311 onto the crushing module 2 below. At this time, the pressure plate 51 continues to move downward, thereby pushing the compressed plastic product into the crushing module 2 and applying a certain pressure to the compressed plastic product to accelerate the crushing of the plastic product. After the processing is completed, the pressing plate 51 is driven to move upward through the lifting unit 4. When the pressing plate 51 moves again to be flush with the connecting rod 522, the electromagnet 64 will be energized to work, and the electromagnetic force of the electromagnet 64 will cause the first plug block 62 to retract into the mounting hole 611. At this time, the pressing plate 51 can drive the adjusting plate 52 to move upward through the connecting unit 7. When the positioning plug block 65 is disengaged from the first plug hole 612, the connecting unit 7 will automatically connect the adjusting plate 52 to the pressing plate 51 again, until the pressing plate 51 returns to its initial position, and a processing process is completed.

[0018] like Figure 1 and Fig. 9As shown, as a preferred embodiment of the present invention, the crushing module 2 can adopt a crusher in the prior art, specifically, including a crushing box 21 and a driving box 23 installed on the frame 1, two crushing cutter bars 22 are arranged side by side in the crushing box 21, and the crushing cutters on the two crushing cutter bars 22 are arranged alternately, and a drop port 24 is provided at the bottom of the crushing box 21, and the driving box 23 is connected to the two crushing cutter bars 22 at the same time, and is used to drive the two crushing cutter bars 22 to rotate in opposite directions at the same time.

[0019] In the embodiment of the present invention, the driving box 23 can adopt the mechanism of the motor plus the gear pair in the prior art, and can also be used in conjunction with the pulley mechanism. It only needs to drive the two crushing cutter bars 22 to rotate at the same time, and the rotation direction of the two crushing cutter bars 22 must ensure that the plastic compressed above can be smoothly crushed and fall to the bottom of the crushing cutter bars 22, and then discharged from the crushing box 21 through the drop port 24 for subsequent processing.

[0020] like Figure 1 and 8 As shown, as a preferred embodiment of the present invention, two groups of adjusting units 8 are provided, and the two groups of adjusting units 8 are symmetrically arranged on both sides of the crushing module 2 (along the sliding direction of the sealing plate 33), and the adjusting unit 8 includes a telescopic cylinder 81 installed on the side wall of the crushing box 21, and the telescopic end of the telescopic cylinder 81 is hinged with a connecting rod 82, and the top of the connecting rod 82 is hinged to the bottom wall of a sealing plate 33.

[0021] In the embodiment of the present invention, in the initial state, the telescopic cylinder 81 is in a retracted state, and the two sealing plates 33 are in a state of abutting each other. At this time, the two sealing plates 33 cooperate to block the feed chute 311, so that the plastic products in the storage module 3 cannot fall through the feed chute 311. After the plastic products in the storage module 3 are compressed, it is only necessary to control the telescopic cylinder 81 to extend, and the telescopic cylinder 81 can drive the two sealing plates 33 to move linearly in opposite directions at the same time through the connecting rod 82, so that the sealing plates 33 are opened to the outside, and the plastic products after compression can fall through the feed chute 311 into the crushing module 2 for crushing. After the crushing is completed, it is only necessary to control the telescopic cylinder 81 to contract again, so that the two sealing plates 33 can abut against each other again, so that the feed chute 311 is blocked again, and the next operation can be performed.

[0022] like Figure 1 As shown, as a preferred embodiment of the present invention, the lifting unit 4 includes a mounting frame 41 mounted on the crushing box 21, and a first hydraulic telescopic rod 42 is installed on the mounting frame 41, and the telescopic end of the first hydraulic telescopic rod 42 is connected to the top of the pressure plate 51.

[0023] In the embodiment of the present invention, when in use, it is only necessary to control the first hydraulic telescopic rod 42 to retract. When the first hydraulic telescopic rod 42 retracts, the first hydraulic telescopic rod 42 can drive the pressure plate 51 to move upward; when the first hydraulic telescopic rod 42 extends, the first hydraulic telescopic rod 42 can drive the pressure plate 51 to move downward.

[0024] like Figure 3-Figure 7 As shown, as a preferred embodiment of the present invention, the connecting unit 7 includes two adjusting sliders 72 symmetrically installed in the connecting rod 522, and the adjusting slider 72 is slidably installed in the connecting rod 522, and a third return spring 73 is also arranged between the adjusting slider 72 and the connecting rod 522, and a second plug block 71 for pushing the adjusting slider 72 to slide is also arranged on the top of the limiting platform 61, and a second inclined surface 721 matching the second plug block 71 is arranged at one end of the second plug block 71, and two third plug blocks 75 are symmetrically arranged on the side wall of the pressing plate 51 close to the adjusting plate 52, and the third plug block 75 is slidably installed in the pressing plate 51, and a fourth return spring 76 is also arranged between the third plug block 75 and the pressing plate 51, a first connecting hole 5221 matching the third plug block 75 is arranged on the connecting rod 522, a stop block 74 is also arranged on the top of the side wall of the connecting rod 522, and a limiting card groove 511 matching the stop block 74 is arranged on the pressing plate 51.

[0025] In the embodiment of the present invention, the installation position of the adjusting slider 72 is located below the stopper 74. When no external force is applied, the third plug 75 will be inserted into the first connection hole 5221, and the stopper 74 will be engaged in the limit slot 511. At this time, the pressing plate 51 can drive the adjusting plate 52 to move up and down synchronously as a whole. When the end of the connecting rod 522 abuts against the limit platform 61 (that is, when the connecting rod 522 contacts the top of the movable side plate 35), the second plug 71 will be inserted into the connecting rod 522, and the adjusting slider 72 will slide a distance under the thrust through the cooperation of the second plug 71 and the second inclined surface 721. At this time, the end of the adjusting slider 72 away from the second plug 71 will contact the third inclined surface 751, and the third plug 75 will be pushed out of the first connection hole 5221 through the third inclined surface 751. At this time, the adjusting plate 52 is fixed, and the connection between the adjusting plate 52 and the pressing plate 51 is disconnected, and the pressing plate 51 can move downward alone.

[0026] During the upward movement of the pressing plate 51, when the stopper 74 is again stuck in the limiting slot 511, the pressing plate 51 can drive the adjusting plate 52 to move upward as a whole through the stopper 74 until the positioning plug 65 is disengaged from the first plug hole 612 (the description of the relevant components of the limiting module 6 is as mentioned above), the second plug 71 will be synchronously withdrawn from the connecting rod 522, and the elastic force of the third return spring 73 will restore the adjusting slider 72 to its initial position. At this time, the elastic force of the fourth return spring 76 will cause the third plug 75 to be inserted into the first connecting hole 5221 again, so that the adjusting plate 52 is connected to the pressing plate 51 again.

[0027] It should be additionally supplemented that the limit slot 511 is opened at the edge of the upper surface of the pressure plate 51, and its upper part is in an open state. When the third inclined surface 751 is disengaged from the first connecting hole 5221, if the pressure plate 51 moves downward, the stop block 74 will automatically disengage from the limit slot 511.

[0028] In addition, the upper part of the end of the third plug block 75 close to the third inclined surface 751 is also processed into an inclined state, thereby ensuring that the third plug block 75 will not get stuck at the bottom of the connecting rod 522 when the third plug block 75 moves from the bottom of the connecting rod 522 to be flush with the first connecting hole 5221.

[0029] Working principle: In the initial state, the pressing plate 51 is located at the upper limit position, and the two movable side plates 35 are both located at the outermost side. The operator can pour the plastic products to be processed into the storage module 3 from the upper side. Then the lifting unit 4 is started, and the pressing plate 51 is driven to move downward by the lifting unit 4. The extrusion module 5 can drive the two adjustment plates 52 to move downward synchronously. In this process, the outer limit plate 523 first contacts the outer wall of the movable side plate 35, and then the inclined push plate 521 contacts the movable side plate 35. Finally, the connecting rod 522 contacts the top of the movable side plate 35, and the movable side plate 35 can be pushed to slide inward by the inclined push plate 521. The plastic products in the storage module 3 are extruded by the mutual cooperation of the two movable side plates 35. When the connecting rod 522 contacts the top of the movable side plate 35, the positioning block 65 will be inserted into the first plug hole 612. During this process, the first inclined surface 652 will first contact the first plug block 62 and push the first plug block 62 into the mounting hole 611. As the positioning block 65 continues to move downward, the elastic force of the second return spring 63 will cause the first plug block 62 to extend from the mounting hole 611 and insert into the plug slot 651, and the adjustment plate 52 will be fixed as a whole. At the same time, the second plug block 71 will be inserted into the connecting rod 522. Through the cooperation between the second plug block 71 and the second inclined surface 721, the adjustment slider 72 will be pushed and slide a distance. At this time, the end of the adjustment slider 72 away from the second plug block 71 will contact the third inclined surface 751, and the third plug block 75 will be pushed out of the first connecting hole 5221 through the third inclined surface 751. At this time, the adjustment plate 52 is fixed, and the connection between the adjustment plate 52 and the pressing plate 51 is disconnected, and the pressing plate 51 can move downward alone, thereby squeezing the plastic products between the two movable side plates 35. When the squeezing reaches a specified degree, the adjustment unit 8 controls the two sealing plates 33 to move in opposite directions at the same time, so that the compressed plastic products can fall from the discharge chute 311 to the crushing module 2 below. At this time, the pressing plate 51 will continue to move downward, thereby pushing the compressed plastic products into the crushing module 2, and applying a certain pressure to the compressed plastic products to accelerate the crushing of the plastic products.

[0030] After the processing is completed, the lifting unit 4 drives the pressing plate 51 to move upward. When the pressing plate 51 moves again to be flush with the connecting rod 522, the stopper 74 will be stuck in the limit slot 511 again, and the electromagnet 64 will be powered on synchronously. The electromagnetic force of the electromagnet 64 causes the first plug 62 to retract into the mounting hole 611. At this time, the pressing plate 51 can drive the adjustment plate 52 to move upward as a whole through the stopper 74. When the positioning plug 65 is disengaged from the first plug hole 612, the second plug 71 will be synchronously withdrawn from the connecting rod 522, and the elastic force of the third return spring 73 will cause the adjustment slider 72 to return to its initial position. At this time, the elastic force of the fourth return spring 76 will cause the third plug block 75 to be inserted into the first connecting hole 5221 again, thereby connecting the adjustment plate 52 to the pressure plate 51 again, until the pressure plate 51 returns to its initial position. At the same time, the adjustment unit 8 controls the two sealing plates 33 to return to their initial positions (mutually abutting against each other). During this process, the elastic restoring force of the first return spring 34 will cause the movable side plate 35 to synchronously return to its initial position, thus completing a processing process.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
