Description

Technical Field

[0001] The present invention relates to a processing device, and more particularly to a rubber particle processing device for recycled rubber. Background Art

[0002] With the booming development of the automotive industry, the recycling of waste tires has become an important issue in the current environmental protection field. The rubber materials contained in waste tires not only have the value of reuse, but also their steel wire mesh layers can be recycled as metal materials. However, traditional waste tire treatment equipment usually faces multiple challenges. Especially in the cutting process of waste tires, how to effectively remove the steel wire mesh layer in the tires and recycle the rubber remains a major problem in the current technology.

[0003] Currently, there are various devices on the market for treating waste tires. Especially in the process of cutting tires, the purpose is to first remove the rubber materials from the inner and outer layers of the tires, and then further process to remove the steel wire mesh layer inside the tires. However, existing devices usually can only achieve single-sided cutting, that is, they can only cut from the inner or outer side of the tires. Traditional treatment methods often have some problems, especially when it is necessary to process the inner and outer circular surfaces of the tires simultaneously.

[0004] The working process of traditional equipment is to first fix the tire, and rotate the tire to use an external cutting mechanism to cut the outer circular surface of the tire until the outer side of the steel wire mesh layer is exposed. After completing the cutting of the outer side, the cutting tool will enter the inner circular surface of the tire for cutting. However, there is a significant problem in this process: when cutting the outer circular surface, the clamping and positioning mechanism is usually fixed on the inner circular surface of the tire. In this way, when it is necessary to cut the inner circular surface, the clamping mechanism originally used to fix the inner circular surface of the tire loses its function, resulting in the inability to continue clamping the inner circular surface. Therefore, it is necessary to replace the clamping method or set multiple sets of positioning and clamping mechanisms. This operation is not only complex but also prone to problems of unstable clamping. Especially as the inner circular surface of the tire becomes thinner, the clamping force gradually weakens, further affecting the cutting accuracy and effect of the inner circular surface.

[0005] Therefore, the treatment devices of the prior art usually need to perform multiple operations of replacing the positioning and clamping mechanisms, increasing the complexity, processing difficulty and time cost of the equipment. In addition, insufficient clamping force may cause the tire to deform or loosen during the cutting process, affecting the stability and accuracy of the cutting, resulting in waste or secondary processing problems. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a rubber particle processing device for recycled rubber, which aims to improve the processing efficiency and accuracy of waste tires by improving the clamping positioning mechanism and the cutting mechanism, ensuring that a stable clamping force can be maintained when cutting the inner and outer circular surfaces of the tire, thereby effectively removing the wire mesh layer and recovering the rubber material.

[0007] The present invention is realized by the following technical scheme: a rubber particle processing device for recycled rubber, comprising: An equipment housing with a base, wherein a mounting bracket is disposed at one end of the equipment housing, and an open clamping and separation cavity is disposed on a side of the equipment housing away from the mounting bracket; A cutting and positioning mechanism is arranged in the clamping and separating cavity.

[0008] As a preferred technical solution, the cutting positioning mechanism includes a driving motor, which is fixedly mounted on the outer side of the mounting bracket, and the output end of the driving motor is connected to a fixed mounting sleeve through a coupling, and an electric push rod is fixedly mounted in the fixed mounting sleeve, and a driving block is arranged at the driving end of the electric push rod, and a first articulated sleeve is fixedly arranged on the driving block, and a second articulated sleeve is arranged at one end of the electric push rod away from the first articulated sleeve, and more than one set of telescopic cutting components are articulated on the circumferential surfaces of the first articulated sleeve and the second articulated sleeve.

[0009] As a preferred technical solution, each set of telescopic cutting assemblies includes an articulated drive rod hingedly arranged on the first articulated sleeve and the second articulated sleeve, and a telescopic blade group is installed between two adjacent articulated drive rods. When the electric push rod pushes out the drive block, the telescopic blade group performs a circular cutting action from the center of the rubber body to be processed toward the outer circle.

[0010] As a preferred technical solution, each telescopic blade group includes a first blade and a second blade. One end of the first blade is hinged to the hinged drive rod on the side of the first hinge bushing, and one end of the second blade is hinged to the hinged drive rod on the side of the second hinge sleeve. The other ends of the first blade and the second blade partially overlap, and a telescopic guiding structure is arranged at the overlapping position.

[0011] As a preferred technical solution, the telescopic guiding structure includes sliding screws arranged on the first blade and the second blade. The sliding screws respectively pass through sliding grooves opened on the first blade and the second blade and are limited by a nut.

[0012] As a preferred technical solution, one or more cutting blocks are arranged at intervals on the first blade and the second blade. A positioning gap cavity is formed between adjacent cutting blocks. One or more cutting blocks are positioned and inserted into a wire mesh inside a rubber body to be processed.

[0013] As a preferred technical solution, a support platform is arranged at the bottom position of the mounting bracket. A conductive slip ring is arranged on the support platform. A conductive brush matched with the conductive slip ring is arranged on the outer shell of the electric push rod. The conductive brush is connected to a power cord inside the electric push rod to ensure stable power supply can be obtained through the conductive slip ring when the electric push rod rotates.

[0014] As a preferred technical solution, the fixed clamping mechanism includes fixed clamping sleeves circumferentially arranged in the clamping and separating cavity. The bottoms of the fixed clamping sleeves are fixed in the clamping and separating cavity. A fixed telescopic sleeve is telescopically arranged in each fixed clamping sleeve. A first clamping convex part is arranged on one side of the fixed telescopic sleeve opposite to the rubber body to be processed. The fixed telescopic sleeve and the fixed clamping sleeve are positioned by locking screws.

[0015] As a preferred technical solution, each movable clamping mechanism includes a driving cylinder. A clamping hinged plate is arranged at the output end of each driving cylinder. The clamping hinged plate is hinged in an opening groove opened on the equipment shell. The driving cylinder is fixedly installed in an annular installation cavity inside the equipment shell. A clamping telescopic plate is telescopically arranged on the clamping hinged plate. A second clamping convex part is arranged on the clamping telescopic plate opposite to the first clamping convex part.

[0016] As a preferred technical solution, the outer cutting mechanism includes a servo motor. The servo motor is fixedly installed on the equipment shell. A lead screw is arranged at the output end of the servo motor through a coupling. A nut block is installed on the lead screw. Guide sliders are respectively arranged on both sides of the nut block.

A cutting tool head is arranged on one side of the tool shank facing the rubber strip to be processed.

[0017] The beneficial effects of the present invention are as follows: The rubber particle processing device for recycled rubber of the present invention realizes efficient cutting processing of the inner and outer circular surfaces of waste tires through a simplified cutting and positioning mechanism. In traditional equipment, it is usually necessary to change the positioning and clamping method to cut the inner and outer circular surfaces of the tire at the same time. However, the present invention allows the use of the same set of cutting and positioning mechanisms for clamping when cutting the inner circular surface of the tire, without the need for additional clamping devices. Specifically, after cutting the inner circular surface of the tire, the cutting and positioning mechanism can drive the tire to rotate circumferentially to continue cutting the outer circular surface.

[0018] The present invention can avoid the problem of unstable clamping caused by multiple changes of clamping methods in the traditional way. As the thickness of the inner circular surface of the tire decreases, the traditional clamping method usually leads to a weakening of the clamping force, thus affecting the cutting accuracy and stability. The present invention enhances the clamping and positioning ability after cutting the inner circular surface by reasonably utilizing the mesh structure of the wire mesh and the block structure of the cutting block, thereby ensuring the accuracy and stability of cutting the outer circular surface.

[0019] In addition, the electric push rod of the present invention pushes out the driving block, enabling the cutting blade to perform circumferential cutting along the inner and outer circular surfaces of the tire during the unfolding process. At the same time, the contraction action of the blade between adjacent two blades enables the blade to not only have strong circumferential cutting ability during cutting, but also perform effective cutting along the axial direction. Through the cooperation of the cutting block and the positioning clearance cavity, the cutting strength of the blade is enhanced, and the cutting effect is improved, enabling the present invention to effectively remove the rubber in the tire and peel off the wire mesh layer.

[0022] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0023] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example in a series of equivalent or similar features.

[0024] As Figure 1 and Figure 2 shown, a rubber particle processing device for recycled rubber according to the present invention includes an equipment housing 1 with a base 2. One end of the equipment housing 1 is provided with a mounting bracket 10, and the mounting bracket 10 is provided with a plurality of hollow areas. The side of the equipment housing 1 facing away from the mounting bracket 10 is provided with an open clamping and separating cavity, and the rubber body 4 to be processed can be loaded into the clamping and separating cavity from the open end; It further includes a cutting and positioning mechanism 6, which is arranged in the clamping and separating cavity. The rubber body 4 to be processed is sleeved outside the cutting and positioning mechanism 6. In this embodiment, the rubber body 4 to be processed is a waste rubber tire. The cutting and positioning mechanism 6 makes a circular cutting motion relative to the inner ring of the rubber tire to realize the cutting of the inner side surface of the rubber body 4 to be processed. Generally, there is no wire mesh layer on the edge of the rubber tire, and only the wire mesh is filled in the circumferential surface. In this embodiment, the cutting and positioning mechanism 6 is used for cutting the side surface of the rubber tire and the inner circumferential surface of the rubber tire until the wire mesh layer is exposed on the inner side surface. When the wire mesh layer is exposed, the cutting and positioning mechanism 6 positions the wire mesh layer. It further includes a fixed clamping mechanism 8 and a movable clamping mechanism 5. The fixed clamping mechanism 8 is arranged in a circular shape in the clamping and separating cavity. The movable clamping mechanism 5 is arranged in a circular shape in the clamping and separating cavity and is located on the opening side of the clamping and separating cavity. Adjacent tires are located between the fixed clamping mechanism 8 and the movable clamping mechanism 5. During installation, first align the side surface of the tire with the fixed clamping mechanism 8, and then the movable clamping mechanism 5 acts to clamp the other side surface of the tire. The positions of the positioning and clamping points of the fixed clamping mechanism 8 and the movable clamping mechanism 5 with the rubber tire are preferably set at the position of the wire layer, so that relatively more rubber layers can be cut off during subsequent cutting.

[0025] It further includes an outer cutting mechanism, which is located at the top position of the clamping and separating cavity. After the inner side surface of the rubber tire is cut, the cutting and positioning mechanism 6 is used as the inner clamping member of the rubber body 4 to be processed, and drives the rubber tire to rotate in a circle relative to the outer cutting mechanism. The outer cutting mechanism cuts the outer side surface of the rubber body 4 to be processed. After the inner circular surface of the rubber tire is cut, the cutting and positioning mechanism 6 can be used as the clamping member of the inner circular surface of the rubber tire to drive the rubber tire to rotate in a circle. At this time, the outer cutting mechanism moves to cut the outer circular surface of the rotating rubber tire.

[0026] As Figure 3 shown, the cutting and positioning mechanism 6 includes a driving motor 3, which is fixedly installed on the outer side surface of the mounting bracket 10. The output end of the driving motor 3 is connected to a fixed mounting sleeve 25 through a coupling. An electric push rod 23 is fixedly installed in the fixed mounting sleeve 25. A driving block 31 is arranged at the driving end of the electric push rod 23. A first hinge shaft sleeve 15 is fixedly arranged on the driving block 31. A second hinge shaft sleeve 14 is arranged at one end of the electric push rod 23 away from the first hinge shaft sleeve 15. More than one set of telescopic cutting components are hinged on the circumferential surfaces of the first hinge shaft sleeve 15 and the second hinge shaft sleeve 14.

[0027] Each telescopic cutting assembly includes an articulated drive rod 16 articulated on the first articulated bushing 15 and the second articulated bushing 14. A telescopic blade group is installed between adjacent articulated drive rods 16. When the electric push rod 23 pushes out the drive block 31, the telescopic blade group makes a circular cutting motion from the center of the rubber body 4 to be processed towards the outer circle.

[0028] As Figure 4 shown, each telescopic blade group includes a first blade 17 and a second blade 22. One end of the first blade 17 is articulated with the articulated drive rod 16 on the side of the first articulated bushing 15, and one end of the second blade 22 is articulated with the articulated drive rod 16 on the side of the second articulated sleeve. The other ends of the first blade 17 and the second blade 22 partially overlap, and a telescopic guiding structure is arranged at the overlapping position.

[0029] The telescopic guiding structure includes sliding screws 27 arranged on the first blade 17 and the second blade 22. The sliding screws 27 respectively pass through sliding grooves 28 opened on the first blade 17 and the second blade 22 and are limited by a nut. The nut is not locked after installation, so that the sliding screws 27 can still slide in the sliding grooves 28. After the electric push rod 23 is pushed out, the drive block 31 moves away from the electric push rod 23. Since the telescopic blade group is articulated with the articulated drive rod 16, after the drive block 31 is pushed out, the telescopic blade group can gradually cut from the center of the rubber tire towards the outer circular surface until it cuts to the position of the wire mesh. After the drive block 31 is pushed out, the first blade 17 and the second blade 22 are compressed relative to each other, and the sliding screws 27 slide. This process is used for cutting in the axial direction of the rubber tire during the cutting movement, while the circular rotation of the telescopic blade group serves as the circular cutting in the radial direction of the rubber tire.

[0030] Among them, one or more cutting blocks 29 are arranged at intervals between the first blade 17 and the second blade 22. A positioning gap cavity 30 is formed between adjacent cutting blocks 29. One or more cutting blocks 29 are positioned and inserted into the wire mesh in the rubber body 4 to be processed. Due to the arrangement of the cutting blocks 29 and the positioning gap cavity 30, it can better fit into various gaps of the wire mesh, better position in the circumferential rotation direction, and then drive the rotation of the rubber tire by the rotation of the blade. At this time, the outer cutting mechanism can be opened for machining the outer circular surface.

[0031] A support platform 7 is arranged at the bottom of the mounting bracket 10. A conductive slip ring 24 is arranged on the support platform 7. A conductive brush cooperating with the conductive slip ring 24 is arranged on the outer shell of the electric push rod 23. The conductive brush is connected to the power cord in the electric push rod 23 to ensure stable power supply can be obtained through the conductive slip ring 24 when the electric push rod 23 rotates.

[0032] Among them, asFigure 3 As shown, the fixed clamping mechanism 8 includes a fixed clamping sleeve 81 circumferentially arranged in the clamping and separating cavity. The bottom of the fixed clamping sleeve 81 is fixed in the clamping and separating cavity. A fixed telescopic sleeve 82 is telescopically arranged in the fixed clamping sleeve 81. A first clamping protrusion is arranged on one side of the fixed telescopic sleeve 82 facing the adjacent tire. The fixed telescopic sleeve 82 and the fixed clamping sleeve 81 are positioned by locking screws. The fixed telescopic sleeve 82 can be stretched to adjust the clamping position point, and after adjustment, the fixed telescopic sleeve 82 can be locked by screws.

[0033] As Figure 3 As shown, the movable clamping mechanism 5 each includes a driving cylinder 26. A clamping hinge plate 52 is arranged at the output end of the driving cylinder 26. The clamping hinge plate 52 is hinged in an opening groove 12 formed on the equipment housing 1. The driving cylinder 26 is fixedly installed in an annular installation cavity 13 inside the equipment housing 1. A clamping telescopic plate 51 is telescopically arranged on the clamping hinge plate 52. A second clamping protrusion is arranged on the clamping telescopic plate 51 opposite to the first clamping protrusion. The clamping telescopic plate 51 and the clamping hinge plate 52 are positioned by locking screws, and the telescopic adjustment method is the same as that of the fixed clamping mechanism 8. After the rubber tire is positioned, the driving cylinder 26 ejects, and using the lever principle of the clamping hinge plate 52, the second clamping protrusion can be used to press the side of the rubber tire, thus completing the positioning and clamping of both sides of the rubber tire.

[0034] Among them, as Figure 5 As shown, the outer cutting mechanism includes a servo motor 9. The servo motor 9 is fixedly installed on the equipment housing 1. A lead screw 19 is arranged at the output end of the servo motor 9 through a coupling. A nut block 111 is installed on the lead screw 19. Guide sliders 32 are respectively arranged on both sides of the nut block 111. The guide sliders 32 are slidably arranged in a guide chute 20. The guide chute 20 is formed on both sides of the inner wall of a cutting sliding cavity 21 formed on the equipment housing 1. The bottom of the nut block 111 is telescopically inserted into a tool bar 112. The nut block 111 and the tool bar 112 are positioned by locking screws. A cutting tool head 113 is arranged on one side of the tool bar 112 facing the rubber strip to be processed. After the inner circular surface of the rubber tire is cut, the outer cutting mechanism can be started, and the lead screw 19 is used to drive the nut block 111 and the cutting tool head 113 to perform a linear cutting action. The whole process does not require multiple disassembly and positioning of the tire, and the efficiency is greatly improved.

[0035] The rubber particle processing device for recycled rubber of the present invention realizes the efficient cutting and processing of the inner and outer circular surfaces of waste tires through a simplified cutting and positioning mechanism 6. The present invention allows the use of the same set of cutting and positioning mechanism 6 for clamping when cutting the inner circular surface of the tire, without the need for additional clamping device replacement. Specifically, after cutting the inner circular surface of the tire, the cutting and positioning mechanism 6 can drive the tire to rotate circumferentially to continue cutting the outer circular surface.

[0036] The present invention can avoid the problem of unstable clamping caused by multiple clamping method replacements in the traditional method. By reasonably utilizing the mesh structure of the wire mesh and the block structure of the cutting block 29, the clamping and positioning ability after cutting the inner circular surface is enhanced, thus ensuring the accuracy and stability of the outer circular surface cutting.

[0037] In addition, when the electric push rod 23 of the present invention pushes out the driving block 31, it can enable the cutting blade to perform circumferential cutting along the inner and outer circular surfaces of the tire during the unfolding process. At the same time, the contraction action of the blade between adjacent blades enables the blade to not only have strong circumferential cutting ability during the cutting process but also perform effective cutting along the axial direction. Through the cooperation of the cutting block 29 and the positioning clearance cavity 30, the cutting strength of the blade is enhanced, and the cutting effect is improved, enabling the present invention to effectively remove the rubber in the tire and peel off the wire mesh layer.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
