Description

Technical Field

[0001] The present application relates to the field of recycling equipment for plastic waste, and in particular to a plastic bottle cap crushing and recycling equipment. Background Art

[0002] Bottle cap recycling equipment is a mechanical device specially used to process waste bottle caps. These devices can improve recycling efficiency, reduce labor costs, and promote the recycling of resources. When recycling these waste bottle caps, they must be crushed. The efficiency of remelting the crushed bottle caps after recycling will be higher, which will help to speed up the recycling efficiency of waste bottle caps. At the same time, the crushed bottle caps are easier to be heated evenly during the smelting process, thereby improving the smelting efficiency and reducing energy consumption.

[0003] In the related art, discarded bottle caps are often crushed by a crushing head. The bottle caps are transported by a conveyor belt to the bottom of the crushing head, and the crushing head is driven by a cylinder to press on the bottle caps to crush the bottle caps. When factories actually process discarded bottle caps, the specifications and models of bottle caps are diverse, which leads to a variety of sizes of bottle caps.

[0004] The authorization announcement number is CN213947109U. A crusher with an easy-to-replace crushing head. When maintaining and replacing the crushing head, the box door can be opened and the third bolt can be unscrewed to remove the sleeve installed on the shaft rod. Then, the eight screws fixing the four arc-shaped blocks can be unscrewed to remove the four arc-shaped blocks with the crushing heads installed, which is convenient for replacement.

[0005] The process of replacing the crushing head requires constant and repeated installation and removal of fasteners such as screws and bolts, which makes the entire replacement process extremely cumbersome when replacing crushing heads of different models and sizes, seriously affecting the efficiency of the waste bottle cap crushing process, and thus being detrimental to daily processing and production.

[0006] At present, the traditional way of replacing the crushing head, whether it is replacing from a large crushing head to a small crushing head or from a small crushing head to a large crushing head, inevitably involves the process of installing and removing the crushing head. When dealing with bottle caps of different sizes, it is necessary to replace the crushing head of the corresponding size to crush the bottle caps, and the repeated replacement and installation of the crushing head will make the entire processing process extremely cumbersome, seriously affecting the efficiency of processing discarded bottle caps, and thus not conducive to daily processing and production. Summary of the invention

[0007] The present application provides a plastic bottle cap crushing and recycling device, the purpose of which is to be able to flexibly replace the corresponding type of crushing head when crushing bottle caps of different sizes, without the need to repeatedly install and remove crushing heads of different specifications and models, which is conducive to speeding up the efficiency of crushing discarded bottle caps and effectively ensuring the daily processing and production of discarded bottle caps.

[0008] The present application provides a plastic bottle cap crushing and recycling device, which adopts the following technical solution:

[0009] A plastic bottle cap crushing and recycling device comprises a conveying mechanism, a feeding mechanism, a transfer seat, a crushing mechanism and a driving mechanism, wherein the conveying mechanism comprises a first conveyor belt and a second conveyor belt, the feeding mechanism comprises a feeder and a suction cup, the transfer seat and the feeder are both slidably mounted in a control box, the suction cup is fixedly mounted at the bottom of the feeder, and the suction cup is used to adsorb bottle caps; the crushing mechanism comprises a first crushing head, a second crushing head and a third crushing head, the first crushing head, the second crushing head and the third crushing head are coaxially connected, and the first crushing head, the second crushing head and the third crushing head are of different sizes, and the driving mechanism is used to drive the first crushing head, the second crushing head or the third crushing head to crush the bottle caps.

[0010] By adopting the above technical solution, when the size of the bottle cap changes, the driving mechanism drives the corresponding first crushing head, the second crushing head or the third crushing head to crush the bottle cap of the corresponding size. With this setting, when crushing bottle caps of different sizes, the staff can flexibly replace the crushing head of the corresponding model, without repeatedly installing and removing redundant fasteners, such as bolts and screws, and when the crushing head is replaced, it is not necessary to install and remove the crushing head, thereby eliminating the steps of repeatedly installing and removing the crushing heads of different models and sizes when replacing them, and further optimizing the process of replacing the crushing heads of different models and sizes, without repeatedly installing and removing the crushing heads of different specifications and models, thereby helping to speed up the efficiency of crushing discarded bottle caps and effectively guarantee the daily processing and production of discarded bottle caps.

[0011] Preferably, a mounting box is fastened in the control box, a mounting seat is provided in the mounting box, the first crushing head is sleeved on the circumferential side of the mounting seat, the driving mechanism comprises a driving box and a driving rod, the driving rod is vertically mounted in the driving box, and the bottom of the driving rod extends downward out of the driving box, the driving box is located directly above the mounting box, and positioning holes for the driving rod to be inserted are provided on the first crushing head, the second crushing head and the third crushing head; the driving rod is provided in plurality, and the plurality of driving rods are slidably arranged in directions approaching or moving away from each other.

[0012] By adopting the above technical scheme, when the transfer seat carries the unbroken bottle cap to the bottom of the installation box, the drive box moves in the direction close to the installation box under the drive of the cylinder, and the drive rod in the drive box extends downward into the installation box and inserts into the positioning holes on the corresponding first crushing head, the second crushing head or the third crushing head. The drive rod and these positioning holes are in a state of micro-interference connection, and the positioning holes are used to effectively ensure the stability of the connection between the drive rod and the first crushing head, the second crushing head or the third crushing head. Then, the drive rod continues to move downward under the drive of the cylinder until the first crushing head, the second crushing head or the third crushing head is pressed on the corresponding bottle cap, and the corresponding bottle cap is crushed. After the bottle cap is crushed, the drive rod rises under the drive of the cylinder, and the first crushing head, the second crushing head or the third crushing head is reset to the installation box under the drive of the drive rod, and the cylinder continues to drive the drive box upward to reset.

[0013] When the size of the bottle cap corresponds to the first crushing head, the distance between the four driving rods does not need to be adjusted, and the first crushing head can be directly pressed down onto the bottle cap under the drive of the cylinder. When the size of the bottle cap corresponds to the second crushing head, the four driving rods slide in a direction away from each other. In this state, the four driving rods correspond to the second crushing head, that is, the four driving rods press down the second crushing head. When the size of the bottle cap corresponds to the third crushing head, the four driving rods continue to slide in a direction away from each other. In this state, the four driving rods correspond to the third crushing head, that is, the four driving rods press down the third crushing head.

[0014] This setting method can flexibly replace the corresponding crushing head to crush the bottle caps by adjusting the distance between the four driving rods. There is no need to repeatedly install and remove crushing heads of different specifications and models, which is beneficial to speed up the efficiency of crushing discarded bottle caps and effectively ensure the daily processing and production of discarded bottle caps.

[0015] Preferably, the drive box is provided with a plurality of telescopic mechanisms, the plurality of telescopic mechanisms correspond to the plurality of drive rods one by one, and the telescopic mechanisms are used to drive the corresponding drive rods to telescopically slide;

[0016] The telescopic mechanism includes a telescopic block, a fixed block, a telescopic spring and a slide plate. The telescopic block is slidably arranged in the driving box along the horizontal direction, and the telescopic block is integrally connected to the top of the driving rod. The fixed block is fixed to the inner wall of the driving box. The telescopic spring is connected between the telescopic block and the fixed block along the horizontal direction. The slide plate is installed between the telescopic block and the top of the fixed block along the horizontal direction. A slide groove is opened at the bottom of the slide plate along its length direction. The top of the telescopic block is integrally connected to a slide block, and the slide block is slidably installed in the slide groove.

[0017] By adopting the above technical solution, the telescopic block can synchronously drive the driving rod to slide during the sliding process in the driving box. During the sliding process of the telescopic block, the slider guides the sliding in the sliding groove, which helps to ensure the stability of the telescopic block during the sliding process.

[0018] Preferably, a rack is provided in the driving box along the vertical direction, a gear is meshed and installed on one side of the rack, a rotating shaft passes through the gear in the horizontal direction, one end of the rotating shaft extends out of the driving box and is rotatably connected to a knob, a conical head is fixed to the bottom of the rack, the circumferential side of the conical head is respectively abutted against one end of a plurality of the telescopic blocks, and the side of the telescopic block abutting against the conical head is an inclined surface.

[0019] By adopting the above technical solution, when the rack rises and falls under the drive of the gear, it simultaneously drives the conical head to rise and fall, and drives the telescopic block to slide through the conical head: when the conical head descends, the four telescopic blocks are driven to slide in the direction away from each other; when the conical head rises, the four telescopic blocks are driven to slide in the direction close to each other.

[0020] Preferably, two groups of stopping mechanisms are provided inside the slide groove, and the two groups of stopping mechanisms are spaced apart along the length direction of the slide plate, and the stopping mechanisms are used to stop the slide block.

[0021] By adopting the above technical solution, when the driving rod at the bottom of the telescopic block slides to the top of the corresponding crushing head, the stop mechanism can stop the slider at the top of the telescopic block, so that the driving rod at the bottom of the telescopic block is just above the positioning hole of the corresponding crushing head. By using the stop mechanism, the staff can quickly and effectively adjust the driving rod to the top of the positioning hole of the corresponding crushing head, thereby effectively improving the efficiency of the driving rod adjustment.

[0022] Preferably, the stopping mechanism includes a baffle, a rotating groove and a torsion spring, the baffle includes a first plate body and a second plate body connected as a whole, the rotating groove is opened on the inner wall of the bottom of the slide groove, the first plate body is arranged in the slide groove in a horizontal direction, and the second plate body is inserted in the rotating groove in a vertical direction, the torsion spring is installed at the bottom of the first plate body away from the second plate body, and the end of the first plate body close to the torsion spring is hingedly connected to the inner wall of the slide groove.

[0023] By adopting the above technical solution, when the size of the bottle cap corresponds to the first crushing head: in this state, the position of the driving rod does not need to be adjusted, and the sliding block remains stationary in the sliding groove.

[0024] When the size of the bottle cap corresponds to the second crushing head: turn the knob to make the rack go down, at this time, the four driving rods slide away from each other, and the slider slides in the corresponding slide groove. When the driving rod slides to the top of the positioning hole of the corresponding second crushing head driven by the telescopic block, the slider slides to the first stop mechanism. The first plate blocks the slider, and under the action of the torsion spring, the slider receives resistance and stops sliding.

[0025] At this time, when the staff turns the knob, they will feel the resistance of the first plate to the slider, and this resistance will remind the staff that the driving rod is now directly above the positioning hole of the second crushing head, and the staff can stop turning the knob. At this time, the driving rod descends and can extend into the positioning hole on the second crushing head to drive the second crushing head downward to crush the corresponding bottle cap.

[0026] When the size of the bottle cap corresponds to the third crushing head: when the staff feels the resistance brought by the slider reaching the first stop mechanism, they can know that the drive rod is now aligned with the second crushing head. The staff continues to turn the knob to apply force to the slider and act on the first plate. In this state, the first plate begins to rotate under the push of the slider, and the second plate rotates in the rotating groove at the same time. When the first plate gradually rotates 90° under the push of the slider, the first plate remains parallel to the groove wall of the slide groove. At this time, the slider breaks through the first stop mechanism and continues to slide toward the second stop mechanism. When the slider slides to the second stop mechanism, the staff feels the second resistance of the slider, and can know that the drive rod is now aligned with the positioning hole on the third crushing head. At this time, the drive rod can be lowered to extend into the positioning hole on the third crushing head to drive the third crushing head downward to crush the corresponding bottle cap.

[0027] Furthermore, the use of the stop mechanism can effectively improve the efficiency of adjusting the driving rod.

[0028] Preferably, a connecting mechanism is provided between the first crushing head, the second crushing head, the third crushing head and the mounting seat, and the connecting mechanism includes a first connecting block, a second connecting block and a third connecting block, the first connecting block is horizontally inserted between the mounting seat and the first crushing head, the second connecting block is horizontally inserted between the first crushing head and the second crushing head, and the third connecting block is horizontally inserted between the second crushing head and the third crushing head.

[0029] By adopting the above technical solution, the first connecting block, the second connecting block and the third connecting block can be used to stably connect the first crushing head, the second crushing head, the third crushing head and the mounting seat, so as to effectively ensure the stability of the connection between the first crushing head, the second crushing head, the third crushing head and the mounting seat.

[0030] Preferably, an accommodating groove is provided through the first crushing head, the second crushing head, the third crushing head and the mounting seat, the first connecting block, the second connecting block and the third connecting block are all horizontally installed in the accommodating groove, the ends of the first connecting block and the second connecting block close to each other are located below the positioning hole of the first crushing head, the ends of the second connecting block and the third connecting block close to each other are located below the positioning hole of the second crushing head, and the end of the third connecting block away from the second connecting block is located below the positioning hole of the third crushing head; the first connecting block is wedge-shaped, and its end close to the second connecting block is inclined; the second connecting block and the third connecting block are both trapezoidal in shape, and the left and right ends of both are inclined, and the left and right ends of the bottom of the driving rod are also inclined.

[0031] By adopting the above technical solution, when the first crushing head is driven downward, the bottom of the driving rod extends into the positioning hole of the first crushing head and abuts against one end of the first connecting block and the second connecting block that are close to each other. Since the bottom of the driving rod, the ends of the first connecting block and the second connecting block are all inclined, the driving rod can squeeze the first connecting block and the second connecting block in a direction away from each other when it descends. As the driving rod continues to press the first crushing head downward, when the first crushing head descends, the left and right side walls of the first crushing head will continue to squeeze the first connecting block and the second connecting block respectively, until the first connecting block and the second connecting block are squeezed to the outside of the first crushing head, and the first crushing head continues to descend under the drive of the driving rod.

[0032] When the second crushing head is driven downward, the bottom of the driving rod extends into the positioning hole of the second crushing head and abuts against the end of the second connecting block and the third connecting block that are close to each other. Since the bottom of the driving rod, the ends of the second connecting block and the third connecting block are all inclined, the driving rod can squeeze the second connecting block and the third connecting block in a direction away from each other when it descends. As the driving rod continues to press the second crushing head downward, when the second crushing head descends, the left and right side walls of the second crushing head will continue to squeeze the second connecting block and the third connecting block respectively, until the second connecting block and the third connecting block are squeezed to the outside of the second crushing head, and the second crushing head continues to descend under the drive of the driving rod.

[0033] When the third crushing head is driven downward, the bottom of the driving rod extends into the positioning hole of the third crushing head and abuts against the inclined end of the third connecting block. Since the bottom of the driving rod and the end of the third connecting block are both inclined, the driving rod can squeeze the third connecting block when it descends. As the driving rod continues to press the third crushing head downward, the side wall of the third crushing head will continue to squeeze the third connecting block when the third crushing head descends, until the third connecting block is squeezed to the outside of the third crushing head, and the third crushing head continues to descend under the drive of the driving rod.

[0034] Then, when the first crushing head, the second crushing head and the third crushing head are pressed down, the sliding of the corresponding first connecting block, the second connecting block and the third connecting block is divided into two stages: in the first stage, the driving rod squeezes the corresponding first connecting block, the second connecting block and the third connecting block, and in the second stage, the side walls of the corresponding first crushing head, the second crushing head and the third crushing head continue to squeeze the corresponding first connecting block, the second connecting block and the third connecting block.

[0035] In this arrangement, when the bottle cap does not need to be crushed, the first crushing head, the second crushing head, the third crushing head and the mounting seat can be stably connected through the first connecting block, the second connecting block and the third connecting block. When the corresponding bottle cap needs to be crushed, when the driving rod presses down the corresponding crushing head, the corresponding first connecting block, the second connecting block and the third connecting block are squeezed, so that the corresponding crushing head can be pressed down smoothly to complete the crushing of the bottle cap.

[0036] Preferably, a limiting plate is provided on the top of the first crushing head, the second crushing head and the third crushing head.

[0037] By adopting the above technical solution, the limit plate can limit the first crushing head, the second crushing head and the third crushing head when they rise and reset, so that the first crushing head, the second crushing head and the third crushing head always maintain the same horizontal height.

[0038] Preferably, a material distributor is provided on the first conveyor belt, and a clamp is provided on the transfer seat.

[0039] By adopting the above technical solution, when the unbroken bottle caps are conveyed on the first conveyor belt, the divider can divide the bottle caps into two rows. The clamp is used to clamp and position the bottle caps to effectively ensure the stability of the bottle caps during the crushing process.

[0040] In summary, the present application includes at least one of the following beneficial technical effects:

[0041] 1. When the size of the bottle cap changes, the driving mechanism drives the corresponding first crushing head, the second crushing head or the third crushing head to crush the bottle cap of the corresponding size. With this setting, when crushing bottle caps of different sizes, the staff can flexibly replace the crushing head of the corresponding type, without the need to repeatedly install and remove redundant fasteners, such as bolts and screws, and when the crushing head is replaced, there is no need to install and remove the crushing head, thereby eliminating the steps of repeatedly installing and removing crushing heads of different sizes as a whole, and further optimizing the process of replacing crushing heads of different sizes. There is no need to repeatedly install and remove crushing heads of different specifications, which is conducive to speeding up the efficiency of crushing discarded bottle caps and effectively ensuring the daily processing and production of discarded bottle caps;

[0042] 2. By adjusting the distance between the four driving rods, the corresponding crushing head can be flexibly replaced to crush the bottle caps. There is no need to repeatedly install and remove crushing heads of different specifications and models, which is conducive to speeding up the efficiency of crushing waste bottle caps and effectively ensuring the daily processing and production of waste bottle caps;

DETAILED DESCRIPTION

[0051] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0052] Example:

[0053] The present application discloses a plastic bottle cap crushing and recycling device, referring to Figure 1 and Figure 2 , including a conveying mechanism 1, a feeding mechanism 2, a transfer seat 3, a crushing mechanism 4 and a driving mechanism 5. The conveying mechanism 1 includes a first conveyor belt 11 and a second conveyor belt 12. The feeding mechanism 2 includes a feeder 21 and a suction cup 22. The transfer seat 3 and the feeder 21 are both slidably installed in the control box. The suction cup 22 is fixedly installed at the bottom of the feeder 21, and the suction cup 22 is used to adsorb the bottle caps.

[0054] When the bottle caps are specifically crushed and recycled, the first conveyor belt 11 is used to convey the unbroken bottle caps to the bottom of the feeder 21, and the bottle caps are adsorbed by the suction cup 22 at the bottom of the feeder 21, and the unbroken bottle caps are moved to the transfer seat 3, and the unbroken bottle caps are moved to the bottom of the crushing mechanism 4 by the transfer seat 3, and then the driving mechanism 5 drives the crushing mechanism 4 to descend, so that the crushing mechanism 4 approaches the direction of the unbroken bottle caps and crushes the bottle caps. The crushed bottle caps are then transported to the bottom of the feeder 21 by the transfer seat 3, and the feeder 21 transports the crushed bottle caps to the second conveyor belt 12, and the crushed bottle caps are transported to the next process by the second conveyor belt 12 for further processing and recycling.

[0055] In this embodiment, refer to Figure 1A divider 24 is installed horizontally on the first conveyor belt 11. When the unbroken bottle caps are conveyed on the first conveyor belt 11, the divider 24 can divide the bottle caps into two rows. At the same time, the feeder 21 is an "X"-shaped structure as a whole, and two suction cups 22 are fixedly installed at both ends.

[0056] In specific operation, when the transfer seat 3 carries the crushed bottle caps to the bottom of the feeder 21, the two suction cups 22 on the side of the feeder 21 absorb the crushed bottle caps, and the two suction cups 22 on the right side of the feeder 21 absorb the unbroken bottle caps, and then the feeder 21 slides to place the two crushed bottle caps on the second conveyor belt 12, and at the same time, the two unbroken bottle caps are placed on the transfer seat 3 and continue to be carried to the bottom of the crushing mechanism 4 for crushing. In addition, the feeder 21 can quickly and effectively improve the efficiency of bottle cap crushing and recycling.

[0057] At the same time, refer to Figure 1 Two clamps 25 are provided on the transfer seat 3, and the two clamps 25 are used to clamp and position the bottle caps to effectively ensure the stability of the bottle caps during the crushing process. The clamp 25 is composed of two clamping blocks arranged opposite to each other, and the two clamping blocks are close to each other in a semicircular shape, so that when clamping the bottle caps, the clamping blocks and the sides of the bottle caps will fit more closely, thereby achieving a better clamping effect on the bottle caps.

[0058] In this embodiment, the transfer seat 3, the feeder 21 and the clamp 25 are all driven by cylinders for lifting and sliding.

[0059] Specifically, refer to Figure 1 , Figure 2 as well as Figure 3 The crushing mechanism 4 includes a first crushing head 41, a second crushing head 42 and a third crushing head 43. The first crushing head 41, the second crushing head 42 and the third crushing head 43 are all ring-shaped and coaxially connected. The first crushing head 41, the second crushing head 42 and the third crushing head 43 are of different sizes. The first crushing head 41 has the smallest diameter, the third crushing head 43 has the largest diameter, and the second crushing head 42 is located between the first crushing head 41 and the third crushing head 43. The driving mechanism 5 is used to drive the first crushing head 41, the second crushing head 42 or the third crushing head 43 to crush the bottle caps.

[0060] When the size of the bottle cap changes, the driving mechanism 5 drives the corresponding first crushing head 41, the second crushing head 42 or the third crushing head 43 to crush the bottle cap of the corresponding size. In this setting mode, when crushing bottle caps of different sizes, the staff can flexibly replace the crushing head of the corresponding model, and there is no need to repeatedly install and remove the crushing heads of different specifications and models, which is conducive to speeding up the efficiency of crushing discarded bottle caps and effectively ensuring the daily processing and production of discarded bottle caps. In this setting mode, when crushing bottle caps of different sizes, the staff can flexibly replace the crushing head of the corresponding model, and there is no need to repeatedly install and remove redundant fasteners, such as bolts and screws. Compared with the traditional way of replacing the crushing head, this replacement method makes it unnecessary to install and remove the crushing head when replacing the crushing head, thereby canceling the steps of repeatedly installing and removing the crushing heads of different models and sizes as a whole, and then optimizing the process of replacing the crushing heads of different models and sizes, and there is no need to repeatedly install and remove the crushing heads of different specifications and models, which is conducive to speeding up the efficiency of crushing discarded bottle caps and effectively ensuring the daily processing and production of discarded bottle caps.

[0061] Specifically, refer to Figure 1 , Figure 2 as well as Figure 3 A rectangular installation box is fastened in the control box by fastening bolts, a mounting seat 6 is vertically installed in the installation box, and the first crushing head 41 is sleeved on the side of the mounting seat 6. The driving mechanism 5 includes a driving box 51 and a driving rod 52, the driving rod 52 is installed in the driving box 51 along the vertical direction, and the bottom of the driving rod 52 extends downward from the driving box 51, and the driving box 51 is located directly above the installation box. An annular opening for the first crushing head 41, the second crushing head 42 and the third crushing head 43 to enter and exit is provided at the bottom of the installation box, and an opening that is connected to the driving box 51 is provided at the top of the installation box. A cylinder is added to the top of the driving box 51, and the driving box 51 is lifted and lowered in the vertical direction under the drive of the cylinder. Positioning holes 7 for the driving rod 52 to penetrate are provided on the first crushing head 41, the second crushing head 42 and the third crushing head 43.

[0062] Specifically, when the transfer seat 3 carries the unbroken bottle cap to the bottom of the installation box, the drive box 51 moves toward the direction close to the installation box under the drive of the cylinder, and the drive rod 52 in the drive box 51 extends downward into the installation box, and is inserted into the corresponding first crushing head 41, the second crushing head 42 or the third crushing head 43. The positioning hole 7 is in a slightly interference connection state between the drive rod 52 and these positioning holes 7, and the positioning hole 7 is effectively used to ensure the stability of the connection between the drive rod 52 and the first crushing head 41, the second crushing head 42 or the third crushing head 43. Then, the drive rod 52 continues to move downward under the drive of the cylinder until the first crushing head 41, the second crushing head 42 or the third crushing head 43 is pressed on the corresponding bottle cap, and the corresponding bottle cap is crushed. After the bottle cap is crushed, the drive rod 52 rises under the drive of the cylinder, and the first crushing head 41, the second crushing head 42 or the third crushing head 43 is reset to the installation box under the drive of the drive rod 52, and the cylinder continues to drive the drive box 51 upward to reset.

[0063] In this embodiment, there are four driving rods 52, which are distributed in the driving box 51 in a "cross" structure, and the four driving rods 52 are slidably arranged in a direction of approaching or moving away from each other. This allows the distance between the four driving rods 52 to be adjusted.

[0064] When the size of the bottle cap corresponds to the first crushing head 41, the distance between the four driving rods 52 does not need to be adjusted, and the first crushing head 41 can be directly pressed down onto the bottle cap under the drive of the cylinder. When the size of the bottle cap corresponds to the second crushing head 42, the four driving rods 52 slide in a direction away from each other. In this state, the four driving rods 52 correspond to the second crushing head 42, that is, the four driving rods 52 press down the second crushing head 42. When the size of the bottle cap corresponds to the third crushing head 43, the four driving rods 52 continue to slide in a direction away from each other. In this state, the four driving rods 52 correspond to the third crushing head 43, that is, the four driving rods 52 press down the third crushing head 43.

[0065] This arrangement can flexibly replace the corresponding crushing heads to crush the bottle caps by adjusting the distance between the four driving rods 52, without the need to repeatedly install and remove crushing heads of different specifications and models, thereby helping to speed up the efficiency of crushing discarded bottle caps and effectively ensure the daily processing and production of discarded bottle caps.

[0066] Reference Figure 1 , Figure 2 as well as Figure 3 Four groups of telescopic mechanisms 8 are arranged in the driving box 51. The four groups of telescopic mechanisms 8 correspond to four driving rods 52 one by one. The telescopic mechanisms 8 are used to drive the corresponding driving rods 52 to perform telescopic sliding.

[0067] Specifically, refer to Figure 3 and Figure 4 The telescopic mechanism 8 includes a telescopic block 81, a fixed block 82, a telescopic spring 83 and a slide plate 84. The telescopic block 81 is arranged in the driving box 51 for sliding in the horizontal direction, and the telescopic block 81 is integrally connected to the top of the driving rod 52. During the sliding process of the telescopic block 81 in the driving box 51, the driving rod 52 is synchronously driven to slide. The fixed block 82 is welded on the inner wall of the driving box 51, and the telescopic spring 83 is connected between the telescopic block 81 and the fixed block 82 in the horizontal direction. The telescopic spring 83 can provide a stable buffer for the telescopic block 81 during the sliding process of the telescopic block 81, and at the same time helps the telescopic block 81 to reset quickly and effectively. The slide plate 84 is installed between the top of the telescopic block 81 and the fixed block 82 in the horizontal direction, and a slide groove 9 is provided at the bottom of the slide plate 84 along its length direction. A slider 10 is integrally connected to the top of the telescopic block 81. During the sliding process of the telescopic block 81, the slider 10 guides the sliding in the slide groove 9, thereby helping to ensure the stability of the telescopic block 81 during the sliding process.

[0068] Specifically, refer to Figure 3 A rack 13 is provided in the driving box 51 in the vertical direction, a gear 14 is meshed and installed on one side of the rack 13, a rotating shaft 15 is passed through the gear 14 in the horizontal direction, one end of the rotating shaft 15 extends out of the driving box 51 and is rotatably connected to a knob 16. When the staff rotates the knob 16, the rotating shaft 15 and the gear 14 can be driven to rotate, and the gear 14 drives the rack 13 to rise and fall in the vertical direction during the rotation process.

[0069] Reference Figure 3 A conical head 17 is welded to the bottom of the rack 13, and the circumferential side of the conical head 17 is respectively in contact with one end of the four telescopic blocks 81, and the side of the telescopic block 81 in contact with the conical head 17 is an inclined surface, that is, the telescopic block 81 is wedge-shaped as a whole. When the rack 13 is driven by the gear 14 to rise and fall, it simultaneously drives the conical head 17 to rise and fall, and drives the telescopic block 81 to slide through the conical head 17: when the conical head 17 descends, it drives the four telescopic blocks 81 to slide in a direction away from each other; when the conical head 17 rises, it drives the four telescopic blocks 81 to slide in a direction close to each other.

[0070] When the staff adjusts the driving rod 52 to align with the positioning hole 7 on the corresponding crushing head, it is easy to use excessive force or insufficient force due to manual adjustment, which will cause the driving rod 52 to be unable to be accurately adjusted to the positioning hole 7 on the corresponding crushing head, and then the staff needs to repeatedly adjust and confirm multiple times before the driving rod 52 can be aligned with the positioning hole 7 on the corresponding crushing head, which makes the entire adjustment process of the driving rod 52 more cumbersome, affecting the efficiency of aligning the driving rod 52 with the corresponding crushing head.

[0071] Reference Figure 3 , Figure 4 as well as Figure 5 In order to effectively improve the efficiency of adjusting the driving rod 52, two sets of stop mechanisms 18 are added inside the slide groove 9 of the slide plate 84, and the two sets of stop mechanisms 18 are spaced apart along the length direction of the slide plate 84. When the driving rod 52 at the bottom of the telescopic block 81 slides to the top of the corresponding crushing head, the stop mechanism 18 can stop the slider 10 at the top of the telescopic block 81, so that the driving rod 52 at the bottom of the telescopic block 81 is just above the positioning hole 7 of the corresponding crushing head. With the stop mechanism 18, the staff can quickly and effectively adjust the driving rod 52 to the top of the positioning hole 7 of the corresponding crushing head, thereby effectively improving the efficiency of adjusting the driving rod 52.

[0072] Specifically, refer to Figure 3 , Figure 4 as well as Figure 5 The stop mechanism 18 includes a baffle 181, a rotating groove 182 and a torsion spring 183. The baffle 181 includes a first plate 1811 and a second plate 1812 that are integrally connected. The first plate 1811 and the second plate 1812 are in an "L" shape as a whole. The rotating groove 182 is provided on the inner wall at the bottom of the slide groove 9, and the rotating groove 182 is in an arc shape. The first plate 1811 is arranged in the slide groove 9 in the horizontal direction, and the second plate 1812 is inserted in the rotating groove 182 in the vertical direction. The torsion spring 183 is installed at the bottom of the first plate 1811 away from the second plate 1812, and the end of the first plate 1811 close to the torsion spring 183 is hingedly connected to the inner wall of the slide groove 9.

[0073] When the telescopic block 81 drives the driving rod 52 to slide, the sliding block 10 slides in the sliding groove 9 .

[0074] When the size of the bottle cap corresponds to the first crushing head 41 : in this state, the position of the driving rod 52 does not need to be adjusted, and the slider 10 remains stationary in the slide groove 9 .

[0075] When the size of the bottle cap corresponds to the second crushing head 42: the knob 16 is turned to make the rack 13 descend, at which time, the four driving rods 52 slide in the direction away from each other, and the slider 10 slides in the corresponding slide groove 9. When the driving rod 52 slides down to the top of the positioning hole 7 on the corresponding second crushing head 42 driven by the telescopic block 81, in this state, the slider 10 slides to the first stop mechanism 18. The first plate 1811 blocks the slider 10, and under the action of the torsion spring 183, the slider 10 receives resistance and stops sliding.

[0076] At this time, when the staff member turns the knob 16, he / she will feel the resistance of the first plate 1811 to the slider 10, and this resistance will remind the staff member that the driving rod 52 is now located directly above the positioning hole 7 of the second crushing head 42, and the staff member can stop turning the knob 16. At this time, the driving rod 52 descends and can extend into the positioning hole 7 on the second crushing head 42 to drive the second crushing head 42 downward to crush the corresponding bottle cap.

[0077] When the size of the bottle cap corresponds to the third crushing head 43: When the staff feels the resistance brought by the slider 10 arriving at the first stop mechanism 18, they can know that the drive rod 52 is now aligned with the second crushing head 42. The staff continues to turn the knob 16 to apply force to the slider 10 and act on the first plate 1811. In this state, the first plate 1811 starts to rotate under the push of the slider 10, and the second plate 1812 rotates in the rotating groove 182. When the first plate 1811 gradually rotates 90° under the push of the slider 10, the first plate 1811 remains parallel to the groove wall of the slide groove 9. At this time, the slider 10 breaks through the first stop mechanism 18 and continues to slide toward the second stop mechanism 18. When the slider 10 slides to the second stop mechanism 18, the staff feels the second resistance of the slider 10, and can know that the drive rod 52 is now aligned with the positioning hole 7 on the third crushing head 43. At this time, the driving rod 52 descends and can extend into the positioning hole 7 on the third crushing head 43 to drive the third crushing head 43 downward to crush the corresponding bottle cap.

[0078] Furthermore, the use of the stopping mechanism 18 can effectively improve the efficiency of adjusting the driving rod 52 .

[0079] Further, refer to Figure 3 and Figure 6 A connecting mechanism 19 is provided between the first crushing head 41, the second crushing head 42, the third crushing head 43 and the mounting seat 6. The connecting mechanism 19 includes a first connecting block 191, a second connecting block 192 and a third connecting block 193. The first connecting block 191 is horizontally inserted between the mounting seat 6 and the first crushing head 41, the second connecting block 192 is horizontally inserted between the first crushing head 41 and the second crushing head 42, and the third connecting block 193 is horizontally inserted between the second crushing head 42 and the third crushing head 43. The first connecting block 191, the second connecting block 192 and the third connecting block 193 can stably connect the first crushing head 41, the second crushing head 42, the third crushing head 43 and the mounting seat 6, so as to effectively ensure the stability of the connection between the first crushing head 41, the second crushing head 42, the third crushing head 43 and the mounting seat 6.

[0080] At the same time, the first connecting block 191, the second connecting block 192 and the third connecting block 193 are all slidably arranged in the horizontal direction.

[0081] When the first crushing head 41 needs to be pressed down, the first connecting block 191 and the second connecting block 192 are slid away from each other, so that the locking state between the first crushing head 41 and the mounting seat 6 and the second crushing head 42 is released.

[0082] When the second crushing head 42 needs to be pressed down, the second connecting block 192 and the third connecting block 193 are slid away from each other, so that the locking state between the second crushing head 42 and the first crushing head 41 and the third crushing head 43 is released.

[0083] When the third crushing head 43 needs to be pressed down, the third connecting block 193 is slid to release the locking state between the third crushing head 43 and the second crushing head 42 .

[0084] Specifically, refer to Figure 3 and Figure 6 The first crushing head 41, the second crushing head 42, the third crushing head 43 and the mounting seat 6 are provided with a receiving groove 20, the first connecting block 191, the second connecting block 192 and the third connecting block 193 are all horizontally installed in the receiving groove 20, the end of the first connecting block 191 and the second connecting block 192 close to each other is located below the positioning hole 7 of the first crushing head 41, the end of the second connecting block 192 and the third connecting block 193 close to each other is located below the positioning hole 7 of the second crushing head 42, and the end of the third connecting block 193 away from the second connecting block 192 is located below the positioning hole 7 of the third crushing head 43. The first connecting block 191 is wedge-shaped, and its end close to the second connecting block 192 is tilted; the second connecting block 192 and the third connecting block 193 are both trapezoidal, and both left and right ends are tilted. The left and right ends of the bottom of the driving rod 52 are also tilted.

[0085] When the driving rod 52 drives the corresponding first crushing head 41, the second crushing head 42 or the third crushing head 43, the specific sliding process of the first connecting block 191, the second connecting block 192 and the third connecting block 193 is as follows:

[0086] When the first crushing head 41 is driven to be pressed down, the bottom of the driving rod 52 extends into the positioning hole 7 of the first crushing head 41, and abuts against the end of the first connecting block 191 and the second connecting block 192 that are close to each other. Since the bottom of the driving rod 52, the ends of the first connecting block 191 and the second connecting block 192 are all inclined, the driving rod 52 can squeeze the first connecting block 191 and the second connecting block 192 in a direction away from each other when it descends. As the driving rod 52 continues to press the first crushing head 41, when the first crushing head 41 descends, the left and right side walls of the first crushing head 41 will continue to squeeze the first connecting block 191 and the second connecting block 192 respectively, until the first connecting block 191 and the second connecting block 192 are squeezed to the outside of the first crushing head 41, and the first crushing head 41 continues to descend under the drive of the driving rod 52.

[0087] When the second crushing head 42 is driven downward, the bottom of the driving rod 52 extends into the positioning hole 7 of the second crushing head 42, and abuts against the end of the second connecting block 192 and the third connecting block 193 that are close to each other. Since the bottom of the driving rod 52, the ends of the second connecting block 192 and the third connecting block 193 are all inclined, the driving rod 52 can squeeze the second connecting block 192 and the third connecting block 193 in a direction away from each other when it descends. As the driving rod 52 continues to press the second crushing head 42 downward, when the second crushing head 42 descends, the left and right side walls of the second crushing head 42 will continue to squeeze the second connecting block 192 and the third connecting block 193 respectively, until the second connecting block 192 and the third connecting block 193 are squeezed to the outside of the second crushing head 42, and the second crushing head 42 continues to descend under the drive of the driving rod 52.

[0088] When the third crushing head 43 is driven to be pressed down, the bottom of the driving rod 52 extends into the positioning hole 7 of the third crushing head 43 and abuts against the inclined end of the third connecting block 193. Since the bottom of the driving rod 52 and the end of the third connecting block 193 are both inclined, the driving rod 52 can squeeze the third connecting block 193 when it descends. As the driving rod 52 continues to press the third crushing head 43, the side wall of the third crushing head 43 will continue to squeeze the third connecting block 193 when the third crushing head 43 descends, until the third connecting block 193 is squeezed to the outside of the third crushing head 43, and the third crushing head 43 continues to descend under the drive of the driving rod 52.

[0089] Then, when the first crushing head 41, the second crushing head 42 and the third crushing head 43 are pressed down, the sliding of the corresponding first connecting block 191, the second connecting block 192 and the third connecting block 193 is divided into two stages: in the first stage, the driving rod 52 squeezes the corresponding first connecting block 191, the second connecting block 192 and the third connecting block 193, and in the second stage, the side walls of the corresponding first crushing head 41, the second crushing head 42 and the third crushing head 43 continue to squeeze the corresponding first connecting block 191, the second connecting block 192 and the third connecting block 193.

[0090] In this arrangement, when the bottle cap does not need to be crushed, the first crushing head 41, the second crushing head 42, the third crushing head 43 and the mounting seat 6 can be stably connected through the first connecting block 191, the second connecting block 192 and the third connecting block 193. When the corresponding bottle cap needs to be crushed, the driving rod 52 will squeeze the corresponding first connecting block 191, the second connecting block 192 and the third connecting block 193 when pressing down the corresponding crushing head, so that the corresponding crushing head can be pressed down smoothly to complete the crushing of the bottle cap.

[0091] In this embodiment, the ends of the first connection block 191 and the third connection block 193 that are away from each other are both provided with corresponding reset springs in the horizontal direction, and the bottom of the second connection block 192 is provided with a corresponding hinge rod. The first connection block 191 and the third connection block 193 are smoothly reset under the action of the reset springs, and the second connection block 192 is reset under the action of the hinge rod. During specific assembly, the installation position of the reset springs at the first connection block 191 and the third connection block 193 should be staggered with a certain space from the positioning hole 7 between the corresponding first crushing head 41 and the third crushing head 43, so as to effectively prevent the reset spring from interfering with the downward pressure of the driving rod 52 after the driving rod 52 extends into the corresponding positioning hole 7.

[0092] Further, refer to Figure 2 and Figure 3 A limiting plate 23 is sleeved on the side of the mounting seat 6 in the horizontal direction, and the limiting plate 23 is covered on the first crushing head 41, the second crushing head 42 and the third crushing head 43.

[0093] The limiting plate 23 is provided with corresponding through holes corresponding to the positioning holes 7 on the first crushing head 41, the second crushing head 42 and the third crushing head 43. When the driving rod 52 presses down the corresponding first crushing head 41, the second crushing head 42 and the third crushing head 43, the driving rod 52 first passes through the through hole on the limiting plate 23, and then extends into the positioning holes 7 on the corresponding first crushing head 41, the second crushing head 42 and the third crushing head 43. The limiting plate 23 can limit the first crushing head 41, the second crushing head 42 and the third crushing head 43 when the first crushing head 41, the second crushing head 42 and the third crushing head 43 are raised and reset, so that the first crushing head 41, the second crushing head 42 and the third crushing head 43 always maintain the same horizontal height.

[0094] The implementation principle of a plastic bottle cap crushing and recycling device in the embodiment of the present application is as follows:

[0095] The first conveyor belt 11 is used to convey the unbroken bottle caps to the bottom of the feeder 21, and the suction cup 22 at the bottom of the feeder 21 adsorbs the bottle caps and moves the unbroken bottle caps to the transfer seat 3, and moves the unbroken bottle caps to the bottom of the crushing mechanism 4 through the transfer seat 3, and then the driving mechanism 5 drives the crushing mechanism 4 to descend, so that the crushing mechanism 4 approaches the unbroken bottle caps and crushes the bottle caps. The crushed bottle caps are then transported to the bottom of the feeder 21 through the transfer seat 3, and the feeder 21 transports the crushed bottle caps to the second conveyor belt 12, and the crushed bottle caps are transported to the next process through the second conveyor belt 12 for further processing and recycling.

[0096] The crushing mechanism 4 includes a first crushing head 41, a second crushing head 42 and a third crushing head 43, which are all annular and coaxially connected. The first crushing head 41, the second crushing head 42 and the third crushing head 43 are of different sizes, the first crushing head 41 has the smallest diameter, the third crushing head 43 has the largest diameter, and the second crushing head 42 is located between the first crushing head 41 and the third crushing head 43. The driving mechanism 5 is used to drive the first crushing head 41, the second crushing head 42 or the third crushing head 43 to crush the bottle cap.

[0097] When the size of the bottle cap changes, the driving mechanism 5 drives the corresponding first crushing head 41, the second crushing head 42 or the third crushing head 43 to crush the bottle cap of the corresponding size. In this arrangement, when crushing bottle caps of different sizes, the staff can flexibly replace the corresponding type of crushing head, and there is no need to repeatedly install and remove crushing heads of different specifications and models, which is conducive to speeding up the efficiency of crushing waste bottle caps and effectively ensuring the daily processing and production of waste bottle caps.

[0098] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
