Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste tire recycling and processing, and particularly relates to a waste tire shredder with an anti-winding structure. BACKGROUND

[0002] Mechanical shredding is a pre-process of tire recycling and processing. During operation, tires are fed into a feed inlet and are gripped, sheared and pulled by a rotating cutter head, and are finally shredded. However, due to the high elasticity and toughness of the tires, after being fed into the feed inlet, the whole tire is likely to bounce or roll on the feed hopper and above the cutter head and is difficult to be stably captured by the cutter head. Even if the tire contacts the cutter head, it is likely to be bounced away or only the surface is cut due to uneven force, and cannot be effectively gripped, resulting in poor feeding and low production efficiency.

[0003] Furthermore, once the cutter head grips the tire, under the action of strong rotating tension, the tire is torn into long strip-shaped rubber belts, and the embedded steel cord has high strength. These long strip-shaped rubber and steel wire mixtures are extremely easy to wind around the cutter head and cutter shaft, or to accumulate into a mass in the gap between the cutter head and the box. Severe winding can instantaneously increase the load of the equipment, causing motor overload, abnormal wear of the cutter head, even breakage, and forcing production to stop. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a waste tire shredder with an anti-winding structure to solve the technical problems of easy winding, blocking and shutdown of tires during shredding in the prior art.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] The waste tire shredder with an anti-winding structure comprises a housing, an internal space formed in the housing, and a plurality of cutter heads arranged in the internal space and capable of rotating relative to the housing to shred tires; the shredder further comprises:

[0007] a frame body arranged in the housing and having a feeding channel capable of communicating with the internal space, the feeding channel being located above the internal space to guide the tires to fall into the internal space;

[0008] at least one auxiliary tool arranged in the frame body and comprising:

[0009] a first base slidingly arranged in the frame body in the up-down direction;

[0010] a second base slidingly arranged in the first base in the left-right direction;

[0011] The adjusting seat group comprises a first adjusting seat and a second adjusting seat arranged along the front-rear direction on the second base, the first adjusting seat and the second adjusting seat are respectively provided with a protrusion and a groove, so that the protrusion is suspended into the groove;

[0012] The puncture head is arranged on the protrusion and is provided with a puncture state when rotating in a first direction and a release state when rotating in a second direction opposite to the first direction, one of the first adjusting seat and the second adjusting seat slides to push the puncture head to switch between the puncture state and the release state;

[0013] In the puncture state, the puncture head is pierced into the tire located in the feeding channel through the sliding of the second base, for supporting the tire;

[0014] In the release state, the first base slides in the same direction with the downward pulling force applied on the tire by the cutter head, and the puncture head is extended out of the tire to release the tire.

[0015] Further, the groove is respectively provided with a first inner wall and a second inner wall along the front-rear direction, the first inner wall and the second inner wall selectively abut against the puncture head through the sliding of one of the first adjusting seat and the second adjusting seat.

[0016] Further, the first inner wall is arranged in an inclined manner, so as to be arranged in an inclined manner after abutting against the puncture head, and is configured as the release state.

[0017] Further, the groove is provided with a limiting end face, the limiting end face abuts against the puncture head when the puncture head is in the release state.

[0018] Further, the second adjusting seat is provided with a avoiding opening, the avoiding opening communicates with the groove to avoid the puncture head.

[0019] Further, the second inner wall extends in a planar manner, so as to be laterally pierced into the tire after abutting against the puncture head, and is configured as the puncture state.

[0020] Further, the puncture head comprises a first segment and a second segment arranged at an angle, the first segment extends outward to form a mounting ear for being rotatably connected to the protrusion, and the second segment is formed with a pointed end for being pierced into the tire.

[0021] Further, the first segment is detachably connected with the mounting ear.

[0022] Further, the frame body, the first base and the second base are all provided with sliding rails, for slidingly arranging the first base, the second base, the first adjusting seat and the second adjusting seat on the corresponding sliding rails.

[0023] Furthermore, the feeding channel is provided with a feeding ramp, the feeding ramp is inclined, and the auxiliary tooling is located at or near the lower end of the feeding ramp.

[0024] Compared to existing technologies, this invention offers the following advantages: The piercing head, pushed by one of the adjusting seats, can rotate to a piercing state and, driven by the second base, pierces into the tire, forming a reliable grip. This prevents the tire from bouncing or rolling within the feed channel and internal space, ensuring it is stably supported in a predetermined position. This guarantees precise and effective engagement of the cutter head with the tire, avoiding disorderly pulling and reducing the risk of entanglement and blockage. Furthermore, the other adjusting seat, in conjunction with the first base, allows the piercing head to enter a release state, gradually releasing the tire while it is being shredded by the cutter head. This ensures the continuity and efficiency of the operation, preventing destructive resistance between the fixed point and the cutter head. It ensures that the tire, once gripped by the cutter head, can enter the deep shredding zone without obstruction, preventing production interruptions caused by interventional shutdowns for cleaning. Simultaneously, the up-and-down sliding of the first base, the left-and-right sliding of the second base, and the forward-and-backward sliding of the adjusting seat assembly provide the auxiliary tooling with multi-degree-of-freedom adjustment capabilities, allowing the piercing head to flexibly adapt to tires of different sizes and orientations.

[0040] The present invention will be further described in detail below through specific embodiments:

[0041] In embodiments of the present invention, such as Figures 1-4 As shown, the waste tire shredder with an anti-tangling structure includes: a housing 1, an internal space 101 formed within the housing 1, and a plurality of cutter discs 102 disposed in the internal space 101. The plurality of cutter discs 102 are arranged in a staggered manner and can rotate relative to the housing 1 to shred the tires.

[0042] The shredder also includes: a frame 2 and at least one auxiliary tooling 3;

[0043] The frame 2 is disposed on the housing 1 and has a feeding channel 201 that can communicate with the internal space 101. The feeding channel 201 is located above the internal space 101 and is used to guide the tire into the internal space 101.

[0044] At least one auxiliary tooling 3 is disposed on the frame 2 and includes: a first base 301, a second base 302, an adjusting seat assembly, and a piercing head 305; the first base 301 is slidably disposed on the frame 2 in the vertical direction; the second base 302 is slidably disposed on the first base 301 in the horizontal direction; the adjusting seat assembly includes a first adjusting seat 303 and a second adjusting seat 304 slidably disposed on the second base 302 in the front-back direction, the first adjusting seat 303 and the second adjusting seat 304 respectively having a protrusion 4 and a groove 5, for the protrusion 4 to be suspended and extended into the groove 5; the piercing head 305 is rotatably disposed on the protrusion 4 and has a piercing state when rotating in a first direction and a releasing state when rotating in a second direction opposite to the first direction; one of the first adjusting seat 303 and the second adjusting seat 304 slides to push the piercing head 305 to switch between the piercing state and the releasing state;

[0045] In the puncture state, the puncture head 305 punctures the tire located in the feed channel 201 by sliding the second base 302, and is used to support the tire;

[0046] In the released state, the first base 301 slides in the same direction as the downward pulling force applied to the tire by the cutter head 102, and the puncture head 305 extends out of the tire to release the tire.

[0047] Specifically, in this embodiment of the invention, the housing 1 is a structure that is closed on all four sides and open at the top and bottom ends. The closed sides form an internal space 101, and the inlet and outlet are respectively formed at the open top and bottom ends of the housing 1. Two rotating shafts are spaced apart within the internal space 101 of the housing 1. These two rotating shafts are driven by a motor (not shown) located outside the housing 1. Each rotating shaft is equipped with multiple cutter discs 102. Adjacent cutter discs 102 at two rotating shafts are staggered so that the cutter discs 102 can engage with the tire when the shaft rotates. Of course, to improve the shearing force of this shredder and avoid entanglement; such as... Figure 1 As shown, a fixed shaft is set between the two rotating shafts. This fixed shaft is also equipped with multiple cutter discs 102. The cutter discs 102 on the rotating shaft are moving cutters, and the cutter discs 102 on the fixed shaft are fixed cutters. The tire is shredded by the interaction of the moving and fixed cutters. That is, the tire enters from the feed inlet, is shredded into pieces by the rotating cutter discs 102, and is discharged from the discharge outlet. However, the tire may bounce or roll at the feed inlet, or it may easily get stuck in the gaps when the cutter discs 102 shred it. Both situations can easily lead to the risk of entanglement, blockage, or machine shutdown.

[0048] Therefore, in this embodiment of the invention, a frame 2 is provided on the upper end face of the housing 1. The frame 2 serves two purposes: firstly, it acts as an installation base for mounting the auxiliary tooling 3 above the inlet; secondly, it serves as an inlet channel 201 for guiding the tire into the internal space 101. Of course, the width of the inlet channel 201 can be adaptively adjusted according to the size of the tire to constrain its posture, allowing it to fall vertically into the internal space 101 for shredding.

[0049] When the tire is in the feed channel 201 but has not completely fallen into the internal space 101, the auxiliary tool 3 is used to fix it in that position so that the bottom of the tire is torn apart first; at the same time, it can continuously provide a downward pressure on the tire to prevent it from jumping. When its bottom is torn apart, in order to ensure the continuity of the process, the auxiliary tool 3 needs to release the tire at this time, which not only allows the tire to be torn into pieces, but also allows the tire to maintain its initial posture and enter the deep tearing zone.

[0050] Specifically, the auxiliary tooling 3 includes: a first base 301, a second base 302, a first adjusting seat 303, a second adjusting seat 304, and a piercing head 305. The first base 301 is slidably connected to the frame 2 in the vertical direction, the second base 302 is slidably connected to the first base 301 in the horizontal direction, and the first adjusting seat 303 and the second adjusting seat 304 are stacked and can both be slidably connected to the second base 302 in the front-back direction. In this way, each component can drive other components to move together in its corresponding direction, forming a multi-degree-of-freedom adjustment structure. In addition, the first adjusting seat 303 is integrally formed with a protrusion 4 for suspended insertion into the groove 5 formed in the second adjusting seat 304, and the piercing head 305 is rotatably connected to the protrusion 4. Because there is a gap between the protrusion 4 and the groove 5, when one of the first adjusting seat 303 or the second adjusting seat 304 slides relative to the other, the piercing head 305 can be pushed to rotate in the first direction or the second direction (two opposite directions), so that the piercing head 305 is configured to a piercing state or a release state, realizing the cyclic processing of gripping, fixing, tearing and releasing.

[0051] The auxiliary tooling 3 includes the following steps:

[0052] S1. Preparation and Puncture Positioning

[0053] In the initial state, the tire is fed into the feeding channel 201 of the frame 2;

[0054] The first base 301 slides vertically to adjust the height of the entire tooling (this adjustment can also be omitted during the tooling operation and debugging phase). The second base 302 slides horizontally to align the puncture head 305 laterally with the tire (similarly, this adjustment can also be omitted during the tooling operation and debugging phase). One of the first adjusting seat 303 and the second adjusting seat 304 slides relative to the other in the front-back direction to position the puncture head 305 at the appropriate puncture point on the tire.

[0055] The control system drives the second base 302 to slide rapidly to the left or right, causing the sharp piercing head 305 to pierce into the tire rubber, forming a pierced state, thereby firmly hooking and supporting the tire in the predetermined position.

[0056] S2, Stable Support and Initial Tear

[0057] The tire, which is fixed by the puncture head 305, is stabilized in position and orientation and will no longer bounce or roll at the feed inlet.

[0058] Multiple cutter discs 102 begin to rotate. Since the tire is fixed, the rotating cutter discs 102 can precisely bite the edge of the tire and begin to apply a downward tearing force.

[0059] S3, Coordinated Release

[0060] When the downward pulling force applied by the cutter head 102 is transmitted to the punctured tire, this force acts on the puncture head 305 and the entire auxiliary tooling 3 through the tire. At this time, the control system drives another slide in the first adjusting seat 303 and the second adjusting seat 304 to change the relative position of the protrusion 4 and the groove 5, thereby switching the rotational degree of freedom of the puncture head 305, changing it from the puncturing state to a release state where it can rotate in the opposite direction. During the process of the puncture head 305 switching to the release state, the tire is being violently pulled downward by the cutter head 102. Since the puncture head 305 can now rotate in the opposite direction, the downward pulling force of the tire will naturally and passively drag the entire auxiliary tooling 3 downward. For this reason, the first base 301 slides downward to eliminate this pulling force. During the downward sliding process, the tire and the puncture head 305 move relative to each other, allowing the puncture head 305 to disengage from the tire, preventing it from continuously hooking onto the tire and hindering its continued downward movement.

[0061] S4, Cyclic Reset

[0062] The tire is completely brought into the shredding zone by the cutter head 102 for deep crushing to form tire blocks. At the same time, the auxiliary tooling 3 is reset, which raises the first base 301 back to its initial height, and the piercing head 305 switches back to the piercing state, ready to work on the next tire.

[0063] In this embodiment, when the tire's elasticity causes difficulties in feeding and initial tearing, it may not be able to smoothly enter the gap of the cutter head 102, or it may be bounced away or wrapped around the cutter head 102 after contacting it, forming an entanglement. Therefore, the piercing head 305 of the auxiliary tooling 3 can actively pierce the tire located in the feeding channel 201 in the piercing state, firmly supporting and fixing it in a preset position, allowing the tire to contact the cutter head 102 in a stable and controllable posture, ensuring that the cutter head 102 can effectively bite and begin tearing. During this process, no pretreatment of the tire is required, saving time. Furthermore, the dynamic entanglement and pulling of the tire during the tearing process can easily cause it to clump together between the rotating shafts or between the cutter head 102 and the housing 1, forming significant resistance. Therefore, the fixing effect of the piercing head 305 makes the initial tearing position and process of the tire more controllable, reducing the possibility of disorderly fragment splashing and entanglement. Furthermore, when the cutter head 102 bites the tire and begins to pull downwards, a downward pulling force is generated. At this time, with the piercing head 305 in the released state, the first base 301 slides in the same direction as the downward pulling force applied to the tire by the cutter head 102. This prevents the piercing head 305 from rigidly resisting the pulling force of the cutter head 102, allowing it to move downwards and exit the tire. This avoids the tire being held in place by the piercing head 305, which would create a counterforce against the downward tearing force of the cutter head 102. In this way, the auxiliary tooling 3 enables an automatic cycle of pre-fixation, initiation of shredding, and coordinated release, avoiding manual intervention and making the entire process continuous and automated, thus improving the overall operating efficiency and safety of the machine.

[0064] Of course, such as Figure 1 , Figure 2 As shown, two auxiliary tooling fixtures 3 are arranged opposite each other in the left-right direction for synchronously piercing into the tire. Additionally, since the first base 301 needs to move other components downwards, and at least one of these components (e.g., the piercing head 305) will overlap with the frame 2, a notch is provided in the frame 2 in this embodiment to allow the component to move freely, in order to avoid the frame 2 interfering with the movement of this component. In other embodiments, the structure of the frame 2 can be modified to make way for the movement of the corresponding component. Alternatively, the installation direction of the second base 302 and / or the piercing head 305 can be changed; these are not limited to one of these methods here.

[0065] like Figures 3-5 As shown, in one embodiment, the groove 5 has a first inner wall 501 and a second inner wall 502 along the front-rear direction, and the first inner wall 501 and the second inner wall 502 slide through one of the first adjusting seat 303 and the second adjusting seat 304 to abut against the puncture head 305.

[0066] Specifically, to enable the puncture head 305 to switch between puncture and release states when one of the first adjusting seat 303 and the second adjusting seat 304 slides relative to the other, this embodiment provides a first inner wall 501 and a second inner wall 502 in the groove 5. The first inner wall 501 and the second inner wall 502 are arranged in the front-rear direction, so that the first inner wall 501 and the second inner wall 502 can alternately abut against the end face of the puncture head 305. On the one hand, the first inner wall 501 and the second inner wall 502 can push the puncture head 305 to rotate to form the corresponding state. On the other hand, it can also physically limit the puncture head 305 in the current state to restrict its rotation in the opposite direction, forming a self-locking mechanism. The alternating movement of the first adjusting seat 303 and the second adjusting seat 304 can ensure that when one adjusting seat slides and causes a certain inner wall of the groove 5 to occupy the abutment position with the puncture head 305, the other will make way and release the constraint on the puncture head 305 in the other direction.

[0067] Furthermore, such as Figure 5 As shown, in one embodiment, the first inner wall 501 is inclined so that it is tilted after contacting the puncture head 305, thus forming the released state. Specifically, the inclined first inner wall 501 can forcibly change the posture of the puncture head 305. That is, when switching to the released state, the inclined first inner wall 501 actively applies a lateral force during contact with the puncture head 305, forcing the puncture head 305 to deflect to a predetermined tilt angle. In addition, after the tire is punctured and torn, the rubber around the puncture hole may deform or roll up, and the puncture head 305 is easily wrapped by the deformed rubber. When the inclined puncture head 305 is withdrawn, its inclined surface can more effectively push away or flatten the deformed rubber, giving it stronger escape ability and adaptability. Preferably, as shown... Figure 5 As shown, the groove 5 is provided with a limiting end face 503. When the puncture head 305 is in the released state, the limiting end face 503 abuts against the puncture head 305. This limiting end face 503 can cooperate with the first inner wall 501 to constrain the rotation angle of the puncture head 305. Preferably, as shown... Figure 5 As shown, the second adjusting seat 304 is provided with a clearance opening 504, which is connected to the groove 5 to avoid the piercing head 305 and prevent the second adjusting seat 304 from interfering with the rotation of the piercing head 305.

[0068] like Figure 5As shown, in one embodiment, the second inner wall 502 extends in a planar shape to abut against the puncture head 305 and allow it to laterally pierce the tire, thus forming the piercing state. Specifically, the planar second inner wall 502 can establish a non-offset piercing reference, that is, when the planar second inner wall 502 abuts against the puncture head 305, it provides a large area of ​​rigid support surface, so that the puncture head 305 is firmly locked in the current position. When the puncture head 305 pierces the tire laterally under the drive of the second base 302, it avoids slippage or insufficient piercing depth caused by the tilt of the puncture head 305.

[0069] like Figure 6 As shown, in one embodiment, the puncture head 305 includes a first segment and a second segment arranged at an angle. The first segment extends outward to form a mounting lug 6 for rotatably connecting to the protrusion 4, and the second segment has a pointed tip for piercing the tire. Specifically, to facilitate the rotatable mounting of the puncture head 305 to the protrusion 4 and to facilitate its piercing of the tire, this embodiment defines the puncture head 305 as an L-shaped structure, dividing it into a connected first segment and a second segment, i.e., the vertical segment of the puncture head 305 is the first segment, and the horizontal segment is the second segment. Thus, a mounting lug 6 is provided at the first segment, and a pivot is provided at the protrusion 4, allowing the mounting lug 6 to rotate around the pivot, thereby causing the second segment to rotate or swing. Simultaneously, the pointed tip of the second segment facilitates rapid piercing into the tire. Of course, as... Figure 3 , Figure 4 and Figure 6 As shown, the puncture head 305 can be configured in pairs and is symmetrical with respect to the mounting ear 6. Preferably, the first segment is detachably connected to the mounting ear 6 for ease of maintenance and assembly.

[0070] In one embodiment, the frame 2, the first base 301, and the second base 302 are all provided with slide rails 7, for sliding the first base 301, the second base 302, the first adjusting seat 303, and the second adjusting seat 304 on the corresponding slide rails 7. This embodiment is described using the second base 302 as an example. Figure 7 As shown, two slide rails 7 are provided at the second base 302, and the two slide rails 7 are arranged in parallel, so that the first adjusting seat 303 and the second adjusting seat 304 are slidably disposed at the two slide rails 7 respectively. The slide rail 7 can be a groove-shaped structure formed in the second base 302, or it can be a column-shaped structure disposed in the second base 302. Of course, limiting members can also be provided at the corresponding slide rails 7 to limit the movement distance of the corresponding components.

[0071] In order to facilitate the feeding of the tire into the preset position and allow the piercing head 305 to penetrate, the feeding channel 201 is provided with a feeding ramp (not shown). The feeding ramp is inclined, and the auxiliary tooling 3 is located at or near the lower end of the feeding ramp.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
