Description

Technical Field

[0001] The present invention relates to the technical field of plastic cutting and processing, and particularly to a rubber recycling and processing device. Background Art

[0002] Due to the physical properties of high elasticity and strong toughness of rubber waste, it faces core problems such as high transportation costs, large storage space, and high energy consumption for crushing during the recycling and processing. To achieve large-scale and efficient processing, the industry generally adopts hot melting or high-pressure compression processes to pre-integrate loose waste rubber into high-density blocks. This pretreatment method significantly reduces logistics and storage costs and improves the uniformity of raw material feeding; however, the secondary decomposition and crushing process of block rubber poses more stringent requirements on the equipment - it is necessary to achieve precise cutting while overcoming the material's tear strength to avoid increased tool wear or out-of-control fragment size caused by uneven stress distribution, thereby affecting the quality and downstream application value of recycled rubber.

[0003] The current block rubber crushing process usually relies on two independent drive systems. Specifically, one is used to push the raw material into the crushing station, and the other drives a rotating cutter or a hydraulic hammer to perform cutting or impact operations. This separated power configuration leads to the complication of the equipment structure, and the energy consumption superposition during the coordinated operation of the two systems significantly increases the unit processing cost. Especially in continuous operation scenarios, the two drive devices generate ineffective power consumption due to high start-stop frequencies and large load fluctuations, further exacerbating energy waste. Summary of the Invention

[0004] In view of the deficiencies in the above-mentioned background art, the present invention provides a rubber recycling and processing device.

[0005] The present invention adopts the following technical solutions: A rubber recycling and processing device, which includes: A frame, the working plane of the frame is divided into a placement area and a stamping area; An upper sliding seat slidably arranged on the frame relative to the placement area and the stamping area, a longitudinal cutting seat is connected inside the upper sliding seat, a row of strip-shaped first cutters are distributed inside the longitudinal cutting seat, and the longitudinal cutting seat is used to carry a rubber block so that the rubber block is located on each of the first cutters; A first pressing plate arranged above the stamping area; A transmission mechanism is arranged on the side above the frame. The transmission mechanism includes a pressing member, a transmission wheel, a swinging member, and a torsion spring. The pressing member is fixed to the first pressing plate. The transmission wheel is arranged on the side of the upper sliding seat. The swinging member has a transmission arm, a driving arm, and a connecting shaft. Both the transmission arm and the driving arm are fixed to the connecting shaft. The connecting shaft is axially fixed and rotatably assembled on the frame. The transmission arm is provided with a strip-shaped hole penetrating through both sides. The transmission wheel is adaptively embedded in the strip-shaped hole. The torsion spring is sleeved outside the connecting shaft, and one torsion arm of the torsion spring abuts against the frame. The other torsion arm of the torsion spring applies a biasing force to the swinging member in the direction of the placement area, so that the driving arm abuts against the lower part of the pressing member under the action of the torsion spring. Wherein, when the first pressing plate moves downward, the pressing member presses the driving arm downward, driving the transmission arm to pivot and rise around the connecting shaft, so that the strip-shaped hole pushes the transmission wheel to displace towards the stamping area, driving the upper sliding seat to synchronously move to the stamping area. At the same time, the first pressing plate performs a pressing action corresponding to the longitudinal cutting seat, so that the rubber block is squeezed and cut into strip-shaped rubber by the first pressing plate and the first cutting knife.

[0006] In a possible implementation manner, a support arm is fixed at one end of the frame in the stamping area, and a driving cylinder is fixed on the support arm. The rod end of the piston rod of the driving cylinder is fixed to the first pressing plate.

[0007] In a possible implementation manner, first guide columns are fixed on both sides of the frame. First guide holes are arranged at both ends of the first pressing plate, and the first guide holes on both sides of the first pressing plate are respectively sleeved outside the two first guide columns.

[0008] In a possible implementation manner, a first roller is arranged at the end of the driving arm, and the driving arm makes the first roller abut against the lower part of the pressing member under the action of the torsion spring.

[0009] In a possible implementation manner, a guide plate is further fixed at one end of the frame in the stamping area. The guide plate has an upwardly inclined guide slope. When the upper sliding seat moves to the stamping area, the edge of the longitudinal cutting seat facing the stamping area abuts against the guide slope and moves.

[0010] In a possible implementation manner, a first guide roller is arranged at the edge of the longitudinal cutting seat facing the stamping area. When the upper sliding seat moves towards the stamping area, the first guide roller abuts against the guide slope and moves.

[0011] In a possible implementation, second guide posts are fixed on both sides of the upper sliding seat. An axial shoulder is formed on the outer periphery of the lower end of the second guide post. Second guide holes are provided on both sides of the longitudinal cutting seat. The second guide holes on both sides of the longitudinal cutting seat are respectively fitted outside the second guide holes on both sides of the longitudinal cutting seat, so that the longitudinal cutting seat is supported by the axial shoulder. When the longitudinal cutting seat is supported by the axial shoulder, the bottom of the longitudinal cutting seat is higher than the lower edge of the guiding inclined plane.

[0012] In a possible implementation, the device further includes: A second pressing plate flatly fixed on the placing area; A lower sliding seat arranged in the frame. A transverse cutting seat is fixed on the lower sliding seat. A row of strip-shaped second cutting blades are distributed in the transverse cutting seat. The second cutting blades and the first cutting blades are staggered in the orthographic projection direction. The transmission mechanism further includes a connecting rod. The side edges of the upper sliding seat and the lower sliding seat are connected by a group of parallel connecting rods. Both ends of each connecting rod are hinged to the side walls of the upper sliding seat and the lower sliding seat through pivot shafts to form a rotating pair. A baffle is further fixed below one end of the frame in the placing area; Support rails are fixed on both sides inside the frame. The two support rails are respectively used to support both sides of the lower sliding seat. When the lower sliding seat is supported by the support rails, the lower sliding seat is closer to the baffle relative to the upper sliding seat. When the upper sliding seat moves to drive the lower sliding seat to move towards the placing area until it abuts against the baffle, the upper sliding seat continues to slide to drive the lower sliding seat to rise along the baffle until it abuts against the lower side of the second pressing plate.

[0013] In a possible implementation, a rotatable second guide roller is connected to one end of the lower sliding seat facing the baffle. When the upper sliding seat moves to drive the lower sliding seat to move towards the placing area to the baffle, the second guide roller abuts against the baffle.

[0014] In a possible implementation, the support rail is L-shaped. Second connecting pieces are fixed at both ends of both sides of the lower sliding seat. The second connecting pieces are connected to rotatable second rollers. The second rollers roll on the horizontal plane of the support rail.

[0015] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: when the first pressure plate is pressed downward, the flat surface of the pressing member compresses the swing member drive arm, forcing the connecting shaft to generate rotational torque. At this time, the strip-shaped hole in the transmission arm, by constraining the profile of the transmission wheel, converts the rotational motion into a precise linear displacement of the upper slide toward the stamping area, thereby driving the block rubber to slide into the stamping area. Thus, the present invention can simultaneously complete the dual actions of pressing the first pressure plate downward and feeding the upper slide laterally using a single power source. Compared with traditional split drive systems, it can effectively reduce the energy consumption of rubber crushing.

[0016] In addition, after the first pressure plate rises, the torsion spring releases the preload force to push the swinging member to swing toward the placement area, thereby driving the upper slide to reset to the placement area. The self-resetting mechanism that can be formed does not require an additional drive device. This integrated drive mode effectively solves the energy redundancy problem existing in the traditional dual-drive system, and can further reduce the energy consumption of rubber crushing work.

[0032] In order to make the purpose, technical solutions and advantages of this application clearer, the following will further describe this application in detail with reference to the accompanying drawings.

[0033] Hereinafter, terms such as "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.

[0034] In addition, in this application, orientation terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and they may change correspondingly according to the change of the orientation of the components placed in the accompanying drawings.

[0035] The present invention provides a rubber recycling and processing device. As shown in the attached Figures 1 to 3 figures, the device includes a frame 1, an upper sliding seat 2, a lower sliding seat 3, a first pressing plate 4, a second pressing plate 5, and a transmission mechanism 6. Among them, above the frame 1 is a working plane, which is divided into a placement area 101 and a stamping area 102. The placement area 101 is used for placing rubber blocks, and the stamping area 102 is used for crushing rubber blocks. The upper sliding seat 2 and the lower sliding seat 3 are respectively located on the frame 1 and inside the frame 1 and slide relative to the placement area 101 and the stamping area 102. Preferably, sealing plates 13 are installed on each side of the frame 1 to protect the lower sliding seat 3, and a protective cover 14 is fixed on the frame 1 to protect the transmission mechanism 6.

[0036] As shown in the attached Figure 5 , 10As shown in FIGS. 10 and 11, a pair of parallel slide rails 211 are symmetrically and fixedly arranged on both sides above the frame 1, and the slide rails 211 connect the placement area 101 and the stamping area 102. Sliders 212 are fixedly arranged on both sides of the upper slide seat 2, and the sliders 212 on both sides of the upper slide seat 2 are respectively slidably and fittingly arranged on the slide rails 211 on both sides of the frame 1, thereby forming a sliding pair to restrict the upper slide seat 2 to reciprocate only along the working plane between the placement area 101 and the stamping area 102.

[0037] Continue to refer to the attached Figure 5 and 10 FIGS., a longitudinal cutting seat 22 is further connected inside the upper slide seat 2. An array of first cutting blades 221 arranged at equal intervals is built in the longitudinal cutting seat 22, and the first cutting blades 221 are strip-shaped blades with the cutting edges facing upward. By designing to completely accommodate the first cutting blades 221 inside the upper slide seat 2, the risk of scratching caused by direct contact between the operator and the first cutting blades 221 of the longitudinal cutting seat 22 when placing the rubber block is effectively avoided. Specifically, when the upper slide seat 2 is positioned in the placement area 101, the rubber block is lifted to one side edge of the upper slide seat 2, and then the rubber block is introduced into the inside of the upper slide seat 2 through a horizontal pushing action and falls onto the longitudinal cutting seat 22. At this time, the longitudinal cutting seat 22 bears the rubber block and the bottom surface of the rubber block forms a vertical alignment relationship with the cutting edges of the first cutting blades 221. Further, a transition roller 23 is connected above one end of the upper slide seat 2 facing the placement area 101. When placing the rubber block, one end of the rubber block is first lifted and placed on the surface of the transition roller 23 to form an inclined support state, and then the rubber block is translated and conveyed along a low-resistance path to the loading station of the longitudinal cutting seat 22 through the rotation assistance of the transition roller 23. This mechanical guiding structure significantly reduces the manual handling intensity.

[0038] As shown in the attached Figure 5 and 9 FIGS., a first pressing plate 4 is arranged above the stamping area 102. The arrangement method can be that the frame 1 symmetrically fixes first guide columns 411 on both sides of the stamping area 102, and first guide holes are arranged at both ends of the first pressing plate 4. Specifically, linear bearings 412 can be fixed on both sides of the first pressing plate 4, and the inner holes of the linear bearings 412 form the first guide holes. The first guide holes on both sides of the first pressing plate 4 are respectively fittingly arranged outside the two first guide columns 411, thereby forming a movement constraint of a plunger pair to restrict the first pressing plate 4 to only perform lifting and lowering displacement relative to the stamping area 102 in the vertical direction. Referring again to the attached Figure 3 and 13 FIGS., a support arm 11 is fixed at one end of the frame 1 in the stamping area 102, and a driving cylinder 7 is fixed on the support arm 11. The driving cylinder 7 can be a linear actuator with a piston rod such as a cylinder or an oil cylinder. The rod end of the piston rod of the driving cylinder 7 is fixed to the top surface of the first pressing plate 4. Through the axial telescopic movement of the telescopic rod 71, the first pressing plate 4 can be driven to accurately lift and lower along the guiding track of the first guide column 411.

[0039] As shown in the attached Figure 2As shown in the figure, the transmission mechanism 6 is arranged on the side above the frame 1, and the first pressing plate 4 is coupled with the upper sliding seat 2 through the transmission mechanism 6, and the actions of linking the upper sliding seat 2 and the lower sliding seat 3 are coordinated. In a preferred embodiment, the transmission mechanisms 6 are symmetrically arranged on both sides of the frame 1. Referring to the appendix again Figures 6 to 9 , the transmission mechanism 6 includes a pressing member 61, a transmission wheel 62, a swinging member 63, a torsion spring 64, and a connecting rod 65. Among them, the pressing member 61 is fixed to the first pressing plate 4. Preferably, the pressing member 61 is in a Z shape, its upper end is lapped and fixed to the top surface of the first pressing plate 4, and its lower end forms a pressing plane parallel to the working plane of the frame 1. The transmission wheel 62 is arranged on the side surface of the upper sliding seat 2. Preferably, the transmission wheel 62 can be a bearing member, and the inner ring is assembled and fixed through a pin shaft fixed to the side surface of the upper sliding seat 2.

[0040] The swinging member 63 has a transmission arm 631, a driving arm 632, and a connecting shaft 633. One end of the transmission arm 631 and one end of the driving arm 632 are both fixed to the connecting shaft 633, so that the transmission arm 631 and the driving arm 632 are inclined relative to each other, and the fixing manner of the transmission arm 631, the driving arm 632, and the connecting shaft 633 can be direct welding. A bearing seat can be fixed to the side of the frame 1, and the connecting shaft 633 passes through and is fixed to the bearing seat, forming a structure in which the connecting shaft 633 is axially fixed and rotatably assembled to the frame 1. The transmission arm 631 is provided with a strip-shaped hole 634 penetrating both sides, and the transmission wheel 62 is adaptively embedded in the strip-shaped hole 634, so that when the swinging member 63 rotates, the contour of the transmission wheel 62 is constrained by the strip-shaped hole 634 to pull its displacement, driving the upper sliding seat 2 to slide along the trajectory from the placement area {101} to the stamping area {102}. The torsion spring 64 is sleeved around the connecting shaft 633, and one torsion arm of the torsion spring 64 abuts against the working plane of the frame 1, and the other torsion arm of the torsion spring 64 applies a biasing force to the swinging member 63 in the direction of the placement area {101}. The specific implementation method is that a convex push rod 635 is welded and fixed on the side of the driving arm 632 facing the torsion spring 64, and the other torsion arm of the torsion spring 64 abuts against the push rod 635, forming a continuous biasing force to push the driving arm 632 to swing upward, so that the driving arm 632 constantly abuts against the lower part of the pressing member 61 under the pre-tightening action of the torsion spring 64.

[0041] Preferably, a first roller 636 is arranged at the end of the driving arm 632. Under the action of the torsion spring 64, the first roller 636 of the driving arm 632 abuts against the lower part of the pressing member 61, thereby reducing the friction between the pressing member 61 and the driving arm 632. Specifically, this includes reducing the friction between the end of the driving arm 632 and the pressing plane of the pressing member 61 during the process of the pressing member 61 pressing down the driving arm 632 to drive the driving arm 632 to swing downward, and the friction between the driving arm 632 pushing up the pressing member 61 under the torsion action of the torsion spring 64 and causing the driving arm 632 to move relative to the bottom pressing plane of the pressing member 61.

[0042] When the first pressing plate 4 moves downward, the pressing member 61 presses the driving arm 632 to move downward, driving the transmission arm 631 to pivot upward around the connecting shaft 633. The strip-shaped hole 634 pushes the transmission wheel 62 to displace towards the stamping area 102, driving the upper sliding seat 2 to synchronously slide to the positioning position in the stamping area 102. At the same time, the first pressing plate 4 performs a vertical pressing action corresponding to the longitudinal cutting seat 22, pressing the rubber block towards the first cutting knife 221 of the longitudinal cutting seat 22, so that the rubber block is squeezed and cut into strip-shaped rubber by the first pressing plate 4 and the first cutting knife 221, completing the extrusion and cutting of the rubber block. By using a single power source to drive the first pressing plate 4, the dual actions of the downward pressing of the first pressing plate 4 and the lateral feeding of the upper sliding seat 2 can be synchronously completed, which can effectively reduce the energy consumption of the rubber crushing work compared with the traditional split driving system. When the first pressing plate 4 rises, the torsion spring releases the pre-tightening force to push the swinging member 63 to swing towards the placement area 101, driving the upper sliding seat 2 to reset towards the placement area 101, forming a self-resetting mechanism. Without an additional driving device, the energy consumption of the rubber crushing work can be further reduced.

[0043] As shown in the attached Figure 3 and 15 figures, a guide plate 12 is also fixed at one end of the stamping area 102 of the frame 1. The guide plate 12 has an upwardly inclined guide slope. Specifically, the guide plate 12 can be fixed on the front surface of the connecting arm facing the stamping area 102, and the inclination direction of the guide slope is from the placement area 101 to the stamping area 102 and upwardly inclined. Referring again to the attached Figure 14 figures, when the upper sliding seat 2 displaces towards the stamping area 102, the edge of the longitudinal cutting seat 22 on the side facing the stamping area 102 abuts and moves on the guide slope, forcing the longitudinal cutting seat 22 to automatically lift along the trajectory of the guide slope during the movement.

[0044] As shown in the attached Figure 10 and 12 figures, second guide columns 241 are fixed on both sides of the upper sliding seat 2, and a radial shoulder 242 structure is formed at the lower end of each second guide column 241. Second guide holes are provided on both sides of the longitudinal cutting seat 22, and the second guide holes on both sides of the longitudinal cutting seat 22 are respectively sleeved outside the second guide holes on both sides of the longitudinal cutting seat 22, so that the longitudinal cutting seat 22 is supported and positioned by the shoulder 242 without external force. And when the longitudinal cutting seat 22 is supported by the shoulder 242, the bottom of the longitudinal cutting seat 22 is higher than the lower edge of the guide slope. This supported state ensures that the bottom reference plane of the longitudinal cutting seat 22 is always higher than the lower edge of the guide slope, ensuring that the side of the longitudinal cutting seat 22 is accurately aligned with the guide slope when the upper sliding seat 2 approaches the stamping area 102. Further, a first guide roller 223 is provided on the edge of the longitudinal cutting seat 22 facing the stamping area 102. When the upper sliding seat 2 moves towards the stamping area 102, the first guide roller 223 abuts and moves on the guide slope, significantly reducing the movement resistance of the longitudinal cutting seat 22 by converting sliding friction into rolling friction.

[0045] As shown in the attached Figure 4 and 5As shown, the second pressing plate 5 is horizontally fixed on the placement area 101 of the frame 1. A baffle 51 is also fixed below one end of the frame 1 close to the placement area 101. Referring again to the attached Figure 10 and 15 , support rails 311 are fixed on both sides of the baffle 51 inside the frame 1. The support rails 311 are parallel to the above-mentioned slide rails 211, and the two support rails 311 are respectively used to support both sides of the lower slide seat 3, so that the lower slide seat 3 can slide linearly relative to the placement area 101 and the stamping area 102 along the support rails 311. And when the lower slide seat 3 is supported by the support rails 311, the lower slide seat 3 is closer to the baffle 51 relative to the upper slide seat 2. Referring again to the attached Figure 11 , the support rail 311 is L-shaped. Second connectors 33 are fixed at both ends of both sides of the lower slide seat 3. The second connectors 33 are connected to rotatable second rollers 312. The second rollers 312 roll on the horizontal plane of the support rail 311. With this structure, the translational stability and operation smoothness of the lower slide seat 3 are synchronously guaranteed.

[0046] It is worth mentioning that when the upper slide seat 2 slides to the stamping area 102 and the first pressing plate 4 performs a vertical pressing action corresponding to the longitudinal cutting seat 22, and the rubber block is extruded and cut into strip-shaped rubber, since the lower slide seat 3 is in front of the upper slide seat 2, the guide plate 12 can play a guiding role, hold one end of the strip-shaped rubber cut by the longitudinal cutting seat 22, and guide the strip-shaped rubber to naturally slide into the transverse cutting seat 32, preventing the strip-shaped rubber from falling to the ground.

[0047] Continuing to refer to the attached Figure 10 and 15 , a transverse cutting seat 32 is fixed on the lower slide seat 3. An array of second cutting blades 321 arranged at equal intervals is built into the transverse cutting seat 32. The second cutting blades 321 are also strip-shaped blades with the cutting edges facing upwards. And the cutting blades in the transverse cutting seat 32 and the cutting blades in the longitudinal cutting seat 22 are staggered in the orthographic projection direction. After the rubber block is extruded by the first pressing plate 4 and the array of first cutting blades 221 of the longitudinal cutting seat 22 in the stamping area 102, the formed strip-shaped rubber body passes through the gaps between the first cutting blades 221 and falls onto the transverse cutting seat 32, and can be naturally laid horizontally on the array of second cutting blades 321 of the transverse cutting seat 32 (that is, the length direction of the strip-shaped rubber is perpendicular to the length direction of the cutting edges of the second cutting blades 321). This specific blanking posture, combined with the design of the second cutting blades 321 with the cutting edges facing upwards, enables the strip-shaped rubber body straddling the cutting edges of each second cutting blade 321 to be accurately squeezed and cut when the lower slide seat 3 is lifted to the second pressing plate 5 subsequently, so as to efficiently convert the strip-shaped rubber into the required fine particles. Therefore, the staggered design of the cutting blades ensures the key that the strip-shaped rubber can accept the secondary transverse cutting in the best stress posture (horizontally spanning multiple second cutting blades 321), and is the decisive factor for realizing the longitudinal and transverse cutting in a single driving stroke and finally obtaining fine and regular granular products.

[0048] Continuing to refer to the attached Figure 10 and15 , the upper sliding seat 2 and the side of the lower sliding seat 3 are connected by a set of parallel connecting rods 65 to achieve motion coupling and lift the lower sliding seat 3. Specifically, both ends of each connecting rod 65 are hinged to the side wall of the upper sliding seat 2 and the side wall of the lower sliding seat 3 through a pivot to form a rotating pair. Specifically, as shown in the appendix Figure 11 . As shown, on both sides of the upper sliding seat 2, first connecting members 25 extending downward into the frame 1 are fixed. Both ends of the connecting rod 65 are respectively pivotally connected to the first connecting member 25 and the second connecting member 33 to form a rotating pair. When the upper sliding seat 2 is displaced under the action of a driving force towards the placing area 101, the lower sliding seat 3 is forced to translate horizontally synchronously through the transmission of the connecting rod 65 until the lower sliding seat 3 contacts the baffle 51 to form a mechanical limit. At this time, the upper sliding seat 2 continues to displace, and the lower sliding seat 3 is vertically lifted along the guiding surface of the baffle 51 through the geometric constraint of the connecting rod 65. Finally, the cross-cutting seat 32 abuts against the lower surface of the second pressing plate 5, so that each rubber block located on the cross-cutting seat 32 is squeezed and cut off by the second cutting knife 321 of the cross-cutting seat 32 and the second pressing plate 5. Referring to the appendix again Figure 4 , a second guide roller 34 is provided on the surface of the lower sliding seat 3 facing the baffle plate 51. The lower sliding seat 3 contacts the baffle plate 51 through the second guide roller 34 and is vertically lifted along the baffle plate 51, significantly reducing the movement resistance of the lower sliding seat 3 through the conversion from sliding friction to rolling friction.

[0049] In addition, the device of the present invention may further include a conveyor belt. One end of the conveyor belt is located inside the frame 1 and below the second pressing plate 5, so that the granular rubber cut off by the second cutting knife 321 of the cross-cutting seat 32 and the second pressing plate 5 can fall onto the conveyor belt through the gap between two adjacent second cutting knives 321 of the cross-cutting seat 32 and be directly output outside the frame 1 through the conveyor belt, facilitating the collection of the cut and broken granular rubber.

[0050] Push the rubber block from the upper sliding seat 2 into the longitudinal cutting seat 22 to prepare for the cutting operation. The working process of the specific cutting operation is as follows: Start the driving cylinder 7 to execute the instruction for the telescopic rod 71 to extend, so that the telescopic rod 71 drives the first pressing plate 4 to descend. The pressing member 61 presses downward on the driving arm 632 of the swinging member 63, triggering the swinging member 63 to pivot around the connecting shaft 633. Through the contour constraint of the strip-shaped hole 634 of the transmission arm 631 on the transmission wheel 62, its displacement is pulled, converting the rotational motion into a linear displacement, and driving the upper sliding seat 2 to accurately slide towards the stamping area 102. When the upper sliding seat 2 slides to be corresponding under the first pressing plate 4, the first pressing plate 4 continues to descend and apply pressure, forcing the arrayed first cutting knives 221 inside the longitudinal cutting seat 22 to perform orthogonal cutting on the rubber block, generating a continuous strip-shaped rubber body that falls through the gap of the first cutting knives 221 to the bearing surface of the longitudinal cutting seat 22 of the lower sliding seat 3, completing one cutting process; The control drive cylinder 7 executes the retraction command of the telescopic rod 71, driving the first pressure plate 4 and the pressing member 61 upward and reset. The driving arm 632 swings upward under the action of the torque arm preload torque released by the torsion spring 64, driving the transmission arm 631 to swing toward the placement area 101. The strip hole 634 of the transmission arm 631 constrains the transmission wheel 62 to move toward the placement area 101, driving the upper slide 2 to retract synchronously. The parallel double connecting rods 65 transmit the motion to the lower slide 3, causing the lower slide 3 to translate along the support rail 311 toward the baffle 51 until the baffle 51 forms a mechanical stop. Then, as the upper slide 2 continues to move, the geometric constraint formed by the connecting rod 65 forces the lower slide 3 to rise vertically along the guide surface of the baffle 51. At this time, the strip rubber body retained in the cross-cutting seat 32 is cut by the second cutter 321 of the array and the second pressure plate 5 in coordination, producing standard granular rubber, achieving the secondary cutting goal.

[0051] The cut rubber particles fall to the transmission surface of the conveyor belt by gravity and are continuously output to the outside of the frame 1 through the belt conveyor system, thus realizing the fully automatic processing cycle of rubber blocks from raw materials to finished products.

[0052] As can be seen from the above workflow, the present invention can complete the cross-cutting and crisscrossing of rubber blocks with a single retractable stroke of the piston rod of the drive cylinder 7, thereby converting the rubber blocks into fine particles. Relying solely on the linkage effect of the transmission mechanism 6, the first pressing plate 4 and the longitudinal cutting seat 22 perform the primary cutting of the rubber blocks, while the second pressing plate 5 and the transverse cutting seat 32 perform the secondary cutting of the strips of rubber formed by the primary cutting. The overall process exhibits significant energy efficiency, high efficiency, and ease of operation.

[0053] In summary, the present invention divides the working plane of the frame 1 into a placement area 101 and a stamping area 102. The upper slide 2 slides between the placement area 101 and the stamping area 102 via the slide rail 211. The longitudinal cutting seat 22 in the upper slide 2 is provided with an array of first cutters 221, which cooperate with the transition roller 23 to reduce the strength of transporting the block rubber to the longitudinal cutting seat 22. The first pressing plate 4 is driven by the drive cylinder 7 to rise and fall along the first guide column 411, and the upper slide 2 and the lower slide 3 are linked by the transmission mechanism 6, and the guide plate 12 assists in lifting the longitudinal cutting seat 22. The transverse cutting seat 32 in the lower slide 3 is provided with an array of second cutters 321 for cooperation with the second pressing plate 5. During operation, the drive cylinder 7 drives the first pressing plate 4 to press down, driving the upper slide 2 to the stamping area 102. The first cutter 221 of the longitudinal cutting seat 22 and the first pressing plate 4 squeeze and cut the rubber block into strips of rubber, which then fall to the transverse cutting seat 32. When the drive cylinder 7 is reset, the upper slide 2 retracts under the force of the torsion spring 64, causing the lower slide 3 to rise. This allows the second cutter 321 of the cross-cutting seat 32 and the second pressure plate 5 to cut the rubber strips into rubber granules, which are then transported via a conveyor belt. This demonstrates that the apparatus of the present invention achieves longitudinal and transverse cutting with a single drive, offering energy-saving, high-efficiency, and convenient features.

[0054] The above are only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification of the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
