Description

Technical Field

[0001] This utility model relates to the field of rubber and plastic processing equipment technology, and in particular to an adjustable spacing rubber and plastic shoe sole particle crushing roller device. Background Technology

[0002] Rubber and plastic shoe soles are a type of shoe sole material made from rubber and plastic through a specific process. They combine the advantages of both and are widely used in the footwear industry. In the recycling and reprocessing of rubber and plastic shoe soles, the crushing process is an important step.

[0003] Currently, most common rubber and plastic shoe sole crushing roller devices use a fixed-gap roller structure. This type of device has significant limitations in use. Because different subsequent processing techniques require different particle sizes for rubber and plastic shoe soles, fixed-gap roller devices cannot flexibly adjust the size of the crushed particles. When different particle sizes need to be produced, the entire roller system must be replaced, which is not only cumbersome to operate but also increases production and equipment maintenance costs. Therefore, we propose an adjustable-gap rubber and plastic shoe sole particle crushing roller device to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide an adjustable spacing rubber and plastic shoe sole particle crushing roller device, which can solve the technical problem that the existing two crushing rollers have a fixed spacing size and it is difficult to flexibly adjust their spacing.

[0006] To solve the above technical problems, this utility model provides an adjustable spacing rubber and plastic shoe sole particle crushing roller device, which adopts the following technical solution: it includes a crushing box, a control structure is provided at the upper end of the crushing box, a feeding port is fixedly opened at the bottom of the crushing box, and a collection box is provided directly below the feeding port. The collection box is slidably connected inside the crushing box. A first crushing roller and a second crushing roller are respectively arranged in opposite positions inside the crushing box. A connecting shaft is fixedly installed in the middle of the first crushing roller and the second crushing roller, and a drive motor is fixedly connected to one end of each of the two connecting shafts.

[0007] An adjustment structure is provided on the outer wall of the crushing box on one side of the second crushing roller. The adjustment structure includes two sets of positioning seats fixedly installed on both sides of the outer wall of the crushing box. An adjustment screw is rotatably installed inside one set of positioning seats, and a first motor is fixedly installed at one end of the adjustment screw. A nut seat is threadedly connected to the outer wall of the adjustment screw. A drive motor is fixedly installed on the outer wall of the nut seat. One end of the connecting shaft is rotatably installed inside the nut seat, and its extension end is connected to the output end of the drive motor. A guide rod is fixedly installed inside the other set of positioning seats.

[0008] Optionally, the first motor is fixedly installed on the outer wall of the positioning seat, and a guide block is fixedly installed at the bottom of the nut seat and the guide block is slidably connected inside the linear slide rail, which is fixedly installed on the outer wall of the crushing box.

[0009] Optionally, the guide rod is slidably connected to a mounting base, one end of the connecting shaft is rotatably mounted to the mounting base, and two adjustment grooves adapted to the diameter of the connecting shaft are opened on both sides of the outer wall of the crushing box. The upper end of the adjustment groove is fixedly provided with scale lines on the outer wall of the crushing box.

[0010] Optionally, the control structure includes a feed box fixedly installed on the upper end of the crushing box. Guide plates are fixedly installed on both sides inside the feed box, and two limiting grooves are opened on both sides of the inner wall of the feed box. A second motor is fixedly installed inside one of the limiting grooves, and a bidirectional lead screw is fixedly connected to the output end of the second motor.

[0011] Optionally, the bidirectional lead screw is rotatably installed inside the limiting groove, and two limiting blocks are symmetrically threaded to the outer wall of the bidirectional lead screw. There are two sets of limiting blocks, and the two sets of limiting blocks are respectively fixedly installed on both sides of the outer wall of the first baffle and the second baffle.

[0012] Optionally, one set of limiting blocks is slidably connected to the outer wall of the limiting rod, and the limiting rod is fixedly installed inside one of the limiting grooves. The first baffle and the second baffle are adapted to the size of the feed box.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. By setting an adjustment structure, the first motor drives the nut seat on the adjusting screw to move, causing the second crushing roller on the connecting shaft to move along the guide groove. At the same time, the distance of the second crushing roller is precisely controlled by the scale line during movement. Meanwhile, the other end of the connecting shaft slides on the guide rod using the mounting seat, which is conducive to the stable adjustment of the distance between the two crushing rollers, thereby controlling the crushing size of the rubber and plastic shoe sole particles, meeting the particle size requirements of different production processes, improving the applicability of the device, and flexibly adjusting the crushed particle size according to actual needs, avoiding rework and waste caused by particle size not meeting the requirements, and improving production efficiency.

[0014] By setting up a control structure, the two limit blocks on the bidirectional lead screw are driven by the second motor to move relative to each other, which causes the first baffle and the second baffle to move relative to each other to expand the spacing of the feeding port. At the same time, when the first baffle and the second baffle move, they slide and cooperate on the limit rod with another set of limit blocks, which is beneficial to control the feeding of rubber and plastic shoe sole particles, avoids problems such as uneven crushing or blockage caused by manual addition, and improves the crushing stability of particles.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1 —5. This utility model will be described in further detail.

[0024] Reference Figure 1-5 In this embodiment, in order to solve the technical problem that the distance between the two existing crushing rollers is fixed and it is difficult to flexibly adjust the distance, this utility model discloses an adjustable distance rubber and plastic shoe sole particle crushing roller device.

[0025] The system includes a crushing box 1, a control structure 4 at the top of the crushing box 1, a feed port 5 fixedly opened at the bottom of the crushing box 1, and a collection box 6 directly below the feed port 5. The collection box 6 is slidably connected inside the crushing box 1. Inside the crushing box 1, a first crushing roller 7 and a second crushing roller 8 are respectively arranged in opposite positions. A connecting shaft 81 is fixedly installed in the middle of the first crushing roller 7 and the second crushing roller 8, and a drive motor 3 is fixedly connected to one end of each of the two connecting shafts 81.

[0026] An adjustment structure 2 is provided on the outer wall of the crushing box 1 on one side of the second crushing roller 8. The adjustment structure 2 includes two sets of positioning seats 22 fixedly installed on both sides of the outer wall of the crushing box 1. An adjustment screw 23 is rotatably installed inside one set of positioning seats 22, and a first motor 21 is fixedly installed at one end of the adjustment screw 23. A nut seat 24 is threadedly connected to the outer wall of the adjustment screw 23. A drive motor 3 is fixedly installed on the outer wall of the nut seat 24. One end of the connecting shaft 81 is rotatably installed inside the nut seat 24, and its extension end is connected to the output end of the drive motor 3. A guide rod 27 is fixedly installed inside the other set of positioning seats 22.

[0027] Specifically: the first motor 21 is fixedly installed on the outer wall of the positioning seat 22, the bottom of the nut seat 24 is fixedly installed with a guide block 26 and the guide block 26 is slidably connected inside the linear slide rail 25, and the linear slide rail 25 is fixedly installed on the outer wall of the crushing box 1.

[0028] By setting a guide block 26 at the bottom of the nut seat 24, the second crushing roller 8 on the connecting shaft 81 is moved by the nut seat 24 and slides along the linear slide rail 25, so as to avoid the position deviation of the connecting shaft 81 during movement from affecting the crushing size of the particles.

[0029] Specifically, the guide rod 27 is slidably connected to the mounting base 28 on its outer wall, and one end of the connecting shaft 81 is rotatably installed with the mounting base 28. Two adjustment grooves that are compatible with the diameter of the connecting shaft 81 are opened on both sides of the outer wall of the crushing box 1. The upper end of the adjustment groove is fixedly set with scale lines 9 on the outer wall of the crushing box 1.

[0030] By using the mounting base 28 to slide the connecting shaft 81 in the middle of the second crushing roller 8 on the guide rod 27, it is easy to make the movement of the second crushing roller 8 relatively stable and relatively limited.

[0031] Specifically, the control structure 4 includes a feed box 41 fixedly installed on the upper end of the crushing box 1. Guide plates 42 are fixedly installed on both sides inside the feed box 41, and two limiting grooves are opened on both sides of the inner wall of the feed box 41. A second motor 43 is fixedly installed inside one of the limiting grooves, and a bidirectional lead screw 44 is fixedly connected to the output end of the second motor 43.

[0032] By setting two guide plates 42, the placed rubber and plastic shoe sole particles are easily guided and fall between the two baffles, while the bidirectional screw 44 rotates and is limited in the limiting groove.

[0033] Specifically, the bidirectional lead screw 44 is rotatably installed inside the limiting groove, and two limiting blocks 48 are symmetrically threaded on the outer wall of the bidirectional lead screw 44. There are two sets of limiting blocks 48, and the two sets of limiting blocks 48 are respectively fixedly installed on the outer walls of the first baffle 46 and the second baffle 47.

[0034] The first baffle 46 and the second baffle 47 can move relative to each other by using the two limiting blocks 48 on the outer wall to move along the direction of the limiting rod 45, which facilitates the adjustment of the distance between the baffles and thus controls the particle feeding.

[0035] Specifically, a set of limiting blocks 48 are slidably connected to the outer wall of the limiting rod 45, the limiting rod 45 is fixedly installed inside one of the limiting grooves, and the first baffle 46 and the second baffle 47 are adapted to the size of the feed box 41.

[0036] This allows the first baffle 46 and the second baffle 47 to be relatively stable and limited during movement, thereby adjusting the feeding distance and facilitating the adjustment and control of particle feeding, avoiding problems such as excessive feeding causing blockage inside the crushing box 1.

[0037] The specific working principle is as follows: First, the operator puts the rubber and plastic shoe sole particles into the feed box 41, and then guides them into the area above the two baffles through the guide plate 42. Then, based on the particle size and crushing uniformity, the operator turns on the power supply of the outer wall, and drives the second motor 43 to move the two limiting blocks 48 on the bidirectional lead screw 44 outward, causing the first baffle 46 and the second baffle 47 to move outward relative to each other. When the two baffles move, they slide on the limiting rod 45 through another set of limiting blocks 48, which facilitates the adjustment and control of the feeding distance between the first baffle 46 and the second baffle 47. This allows for control of the feeding of rubber and plastic shoe sole particles, avoiding problems such as insufficient crushing or blockage caused by manual pouring, and achieving crushing stability.

[0038] Rubber and plastic shoe sole granules fall from the feed box 41 between the first crushing roller 7 and the second crushing roller 8. By synchronously activating two drive motors 3, the first crushing roller 7 and the second crushing roller 8 rotate relative to each other to crush the granules. When different particle sizes are required, the first motor 21 drives the adjusting screw 23 to rotate within the positioning seat 22, causing the adjusting screw 23 to move the second crushing roller 8, which is fixed on the connecting shaft 81 on the nut seat 24, along the guide groove. At the same time, the second crushing roller 8 is limited by its other end moving along the guide rod 27 on the mounting seat 28. The distance between the two crushing rollers can be precisely adjusted by observing the scale line 9 on the outside of the crushing box 1 during the movement of the second crushing roller 8, thereby controlling the crushing size of the rubber and plastic shoe sole granules and meeting the particle size requirements of different production processes. The operation is simple.
