Description

Technical Field

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

[0002] Due to its high elasticity and toughness, rubber waste faces core challenges during recycling, such as high transportation costs, large storage space, and high crushing energy consumption. To achieve efficient and large-scale processing, the industry generally uses hot melt or high-pressure compression processes to pre-integrate loose waste rubber into high-density blocks. This pretreatment method significantly reduces logistics and warehousing costs and improves the uniformity of raw material feeding; however, the secondary decomposition and crushing process of block rubber places 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 uncontrolled fragment size due to uneven stress distribution, which in turn affects the quality of the recycled rubber and its downstream application value.

[0003] Current block rubber crushing processes typically rely on two independent drive systems: one for pushing the raw material into the crushing station, and the other for driving the rotary cutters or hydraulic hammers for cutting or impacting. This separate power configuration complicates the equipment structure, and the combined energy consumption of the two systems operating in tandem significantly increases unit processing costs. Especially in continuous operation, the frequent start-stop cycles and large load fluctuations of the two drive units result in inefficient power consumption, further exacerbating energy waste. Summary of the Invention

[0004] In view of the deficiencies raised in the above background technology, the present invention provides a rubber recycling and processing equipment.

[0005] The present invention adopts the following technical solutions:

[0006] A rubber recycling and processing device, comprising:

[0007] A frame, wherein a working plane of the frame is divided into a placement area and a stamping area;

[0008] An upper slide is provided on the frame and slides relative to the placement area and the stamping area. The upper slide is connected to a longitudinal cutting seat. A row of strip-shaped first cutting knives are distributed in the longitudinal cutting seat. The longitudinal cutting seat is used to carry the rubber block so that the rubber block is located on each of the first cutting knives.

[0009] a first pressing plate disposed above the stamping area;

[0010] The transmission mechanism is arranged on the upper side of the frame, and the transmission mechanism includes a pressing member, a transmission wheel, a swing member, and a torsion spring, the pressing member is fixed to the first pressure plate, the transmission wheel is arranged on the side of the upper slide, the swing member has a transmission arm, a driving arm and a connecting shaft, the transmission arm and the driving arm are both fixed to the connecting shaft, the connecting shaft is axially fixed and rotatably assembled to the frame, the transmission arm is provided with a strip hole passing through both sides, the transmission wheel is adapted to be embedded in the strip hole, the torsion spring is sleeved outside the connecting shaft, and the torsion arm at one end of the torsion spring is against the frame, and the torsion arm at the other end of the torsion spring applies a biasing force acting on the swing member in the direction of the placement area, so that the driving arm is against the bottom of the pressing member under the action of the torsion spring;

[0011] Among them, when the first pressure plate moves downward, the pressing member presses the driving arm to move downward, driving the transmission arm to pivot and rise around the connecting shaft, so that the strip hole pushes the transmission wheel to move toward the stamping area, driving the upper slide to move synchronously to the stamping area, and at the same time, the first pressure plate performs a downward pressing action corresponding to the longitudinal cutting seat, so that the rubber block is squeezed and cut into strip-shaped rubber by the first pressure plate and the first cutter.

[0012] In a possible implementation, a support arm is fixed to one end of the stamping area of ​​the frame, a driving cylinder is fixed on the support arm, and an end of a piston rod of the driving cylinder is fixed to the first pressing plate.

[0013] In a possible implementation, first guide pillars are fixed on both sides of the frame, first guide holes are provided at both ends of the first pressure plate, and the first guide holes on both sides of the first pressure plate are respectively adapted to fit outside the two first guide pillars.

[0014] In a possible implementation, a first roller is provided at the end of the driving arm, and the driving arm causes the first roller to abut under the pressing member under the action of a torsion spring.

[0015] In one possible implementation, the frame is further fixed with a guide plate on one end of the stamping area, and the guide plate has an upwardly inclined guide slope. When the upper slide moves to the stamping area, the longitudinal cutting seat moves toward one side edge of the stamping area and rests on the guide slope.

[0016] In a possible implementation, a first guide roller is provided on one side edge of the longitudinal cutting seat toward the stamping area, and when the upper slide moves toward the stamping area, the first guide roller moves against the guide slope.

[0017] In one possible implementation, second guide columns are fixed on both sides of the upper slide, and a shoulder is formed on the periphery of the lower end of the second guide column. Second guide holes are provided on both sides of the longitudinal cutting seat, and the second guide holes on both sides of the longitudinal cutting seat are respectively adapted to fit outside the second guide columns on both sides of the upper slide, so that the longitudinal cutting seat is supported by the shoulder, and when the longitudinal cutting seat is supported by the shoulder, the bottom of the longitudinal cutting seat is higher than the lower end edge of the guide slope.

[0018] In one possible implementation, the device further includes:

[0019] a second pressing plate fixed flatly in the placement area;

[0020] A lower slide is provided in the frame, a cross-cutting seat is fixed on the lower slide, a row of strip-shaped second cutters are distributed in the cross-cutting seat, and the second cutters and the first cutters are staggered in the orthographic projection direction;

[0021] The transmission mechanism further includes connecting rods, and the side edges of the upper slide and the lower slide are connected by a set of parallel connecting rods, and the two ends of each connecting rod are respectively hinged to the side walls of the upper slide and the lower slide through a pivot to form a rotating pair;

[0022] The frame is further provided with a baffle fixed below one end of the placement area;

[0023] Support rails are fixed on both sides of the frame, and the two support rails are used to support both sides of the lower slide respectively. When the lower slide is supported by the support rails, the lower slide is closer to the baffle relative to the upper slide;

[0024] When the upper slide moves and drives the lower slide to move toward the placement area and abut against the baffle, the upper slide continues to slide and drives the lower slide to rise along the baffle and abut under the second pressing plate.

[0025] In a possible implementation, the lower slide is connected to a rotatable second guide roller at one end facing the baffle, and when the upper slide moves to drive the lower slide toward the placement area to the baffle, the second guide roller abuts against the baffle.

[0026] In a possible implementation, the supporting rail is L-shaped, and second connecting members are fixed at both ends of the lower sliding seat. The second connecting members are connected to a rotatable second roller, and the second roller rolls on the horizontal plane of the supporting rail.

[0027] 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.

[0028] 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.

[0044] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0045] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0046] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0047] The present invention provides a rubber recycling equipment, as shown in the following Figures 1 to 3 As shown, the device includes a frame 1, an upper slide 2, a lower slide 3, a first pressure plate 4, a second pressure plate 5, and a transmission mechanism 6. Above the frame 1 is a work surface, which is divided into a placement area 101 and a stamping area 102. The placement area 101 is used to place rubber blocks, and the stamping area 102 is used to crush the rubber blocks. The upper slide 2 and the lower slide 3 are respectively located on and within the frame 1, sliding relative to the placement area 101 and the stamping area 102. Preferably, a cover 13 is installed on each side of the frame 1 to protect the lower slide 3, and a protective cover 14 is fixed to the frame 1 to protect the transmission mechanism 6.

[0048] As attached Figure 5 、 10As shown in Figure 11, a pair of parallel slide rails 211 are symmetrically fixed on both sides of the upper portion of the frame 1. The slide rails 211 connect the placement area 101 and the stamping area 102. Slide blocks 212 are fixed on both sides of the upper slide 2. The slide blocks 212 on both sides of the upper slide 2 are slidably adapted to be mounted on the slide rails 211 on both sides of the frame 1, thereby forming a sliding pair to constrain the upper slide 2 to reciprocate translationally between the placement area 101 and the stamping area 102 along the working plane.

[0049] Continue to refer to the attached Figure 5 and 10 The upper slide 2 is also connected to a longitudinal cutting seat 22, which houses an array of evenly spaced first cutters 221, each of which is a strip-shaped blade with its cutting edge facing upward. By completely housing the first cutters 221 within the upper slide 2, the operator is effectively protected from the risk of scratches caused by direct contact with the first cutters 221 of the longitudinal cutting seat 22 when placing the rubber block. Specifically, when the upper slide 2 is positioned in the placement area 101, the rubber block is lifted to a side edge of the upper slide 2, then horizontally pushed into the interior of the upper slide 2 and dropped onto the longitudinal cutting seat 22. At this point, the longitudinal cutting seat 22 supports the rubber block, and the bottom surface of the rubber block forms a vertical alignment with the cutting edges of each first cutter 221. Furthermore, the upper slide 2 is connected to a transition roller 23 above one end of 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. Then, the rotation of the transition roller 23 assists in transporting the rubber block along a low-resistance path to the longitudinal cutting seat 22 supporting station. This mechanical guide structure significantly reduces the intensity of manual handling.

[0050] As attached Figure 5 and 9 As shown, the first pressing plate 4 is arranged above the stamping area 102. The arrangement can be that the frame 1 symmetrically fixes the first guide pillars 411 on both sides of the stamping area 102, and first guide holes are set 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 adapted to fit outside the two first guide pillars 411, thereby forming a piston pair motion constraint, limiting the first pressing plate 4 to only be able to perform lifting and lowering displacements in the vertical direction relative to the stamping area 102. Refer to the attached Figure 3 and 13 The frame 1 is fixed with a support arm 11 at one end of the stamping area 102, and a drive cylinder 7 is fixed on the support arm 11. The drive cylinder 7 can be a linear actuator with a piston rod, such as a pneumatic cylinder or an oil cylinder. The piston rod end of the drive cylinder 7 is fixed to the top surface of the first pressure plate 4. Through the axial telescopic movement of the telescopic rod 71, the first pressure plate 4 can be driven to move along the guide track of the first guide column 411 to achieve precise lifting and lowering.

[0051] As attached Figure 2As shown, the transmission mechanism 6 is arranged on the side above the frame 1, and the first pressing plate 4 is coupled to the upper slide 2 and the upper slide 2 is linked to the lower slide 3 for coordinated action. In a preferred embodiment, the transmission mechanism 6 is symmetrically arranged on both sides of the frame 1. 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. The pressing member 61 is fixed to the first pressure plate 4. Preferably, the pressing member 61 is Z-shaped, with its upper end overlapping and fixed to the top surface of the first pressure plate 4, and its lower end forming a pressing plane parallel to the working plane of the frame 1. The transmission wheel 62 is set on the side of the upper slide 2. Preferably, the transmission wheel 62 can be a bearing component, and the inner ring is assembled and fixed by a pin fixed to the side of the upper slide 2.

[0052] The swing 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 fixed to the connecting shaft 633, so that the transmission arm 631 and the driving arm 632 are relatively tilted. The transmission arm 631, the driving arm 632, and the connecting shaft 633 can be fixed by direct welding. A bearing seat can be fixed on the side of the frame 1. 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 hole 634 running through both sides. The transmission wheel 62 is adapted to be embedded in the strip hole 634, so that when the swing member 63 rotates, the strip hole 634 constrains the transmission wheel 62 to move its position through the contour constraint of the transmission wheel 62, driving the upper slide 2 to slide along the trajectory from the placement area 101 to the stamping area 102. The torsion spring 64 is sleeved on the outer periphery of the connecting shaft 633, and the torsion arm at one end of the torsion spring 64 is against the working plane of the frame 1, and the torsion arm at the other end of the torsion spring 64 applies a biasing force on the swinging member 63 toward the placement area 101. The specific implementation method is that the driving arm 632 is welded with a fixed protruding push rod 635 toward one side of the torsion spring 64, and the torsion arm at the other end of the torsion spring 64 is against the push rod 635, forming a continuous biasing force that pushes the driving arm 632 to swing upward, so that the driving arm 632 is constantly against the bottom of the pressing member 61 under the pre-tightening action of the torsion spring 64.

[0053] Preferably, a first roller 636 is provided at the end of the driving arm 632. Under the action of the torsion spring 64, the driving arm 632 makes the first roller 636 abut against the bottom 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 in the process of the pressing member 61 pressing down the driving arm 632 and driving the driving arm 632 to swing downward, and the friction caused by the driving arm 632 lifting the pressing member 61 under the torsion of the torsion spring 64, causing the driving arm 632 to move relative to the pressing plane at the bottom of the pressing member 61.

[0054] When the first pressing plate 4 moves downward, the pressing member 61 compresses the driving arm 632 downward, driving the transmission arm 631 to pivot upward about the connecting shaft 633. The strip hole 634 pushes the transmission wheel 62 toward the stamping area 102, causing the upper slide 2 to slide synchronously to the positioning position in the stamping area 102. At the same time, the first pressing plate 4 performs a vertical downward pressing action corresponding to the longitudinal cutting seat 22, pressing the rubber block toward the first cutter 221 of the longitudinal cutting seat 22. The rubber block is squeezed and cut into strips by the first pressing plate 4 and the first cutter 221, completing the extrusion and cutting of the rubber block. Using a single power source to drive the first pressing plate 4 can simultaneously complete the dual actions of pressing the first pressing plate 4 downward and feeding the upper slide 2 horizontally. Compared with traditional split drive systems, this can effectively reduce the energy consumption of the rubber crushing operation. When the first pressure plate 4 rises, the torsion spring releases the preload force to push the swing member 63 to swing toward the placement area 101, thereby driving the upper slide 2 to reset to the placement area 101. This self-resetting mechanism does not require an additional drive device, and can further reduce the energy consumption of the rubber crushing operation.

[0055] As attached Figure 3 and 15 As shown, the frame 1 is further fixed with a guide plate 12 at one end of the stamping area 102. The guide plate 12 has an upwardly inclined guide slope. Specifically, the guide plate 12 can be fixed on the front side of the connecting arm facing the stamping area 102. The inclined direction of the guide slope is from the placement area 101 to the stamping area 102 and is upwardly inclined. Figure 14 When the stamping area 102 of the upper slide 2 moves, the longitudinal cutting seat 22 moves toward the edge of the stamping area 102 and against the guide slope, forcing the longitudinal cutting seat 22 to automatically rise along the guide slope track during the movement.

[0056] As attached Figure 10 and 12 Second guide posts 241 are fixed on both sides of the upper slide 2, and the lower end of each second guide post 241 is machined to form a radial shoulder 242 structure. 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 adapted to fit outside the second guide posts 241 on both sides of the upper slide 2, so that the longitudinal cutting seat 22 is supported and positioned by the shoulder 242 without external force. 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 supporting state ensures that the bottom reference surface 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 slide 2 approaches the stamping area 102. Furthermore, a first guide roller 223 is provided on one side edge of the longitudinal cutting seat 22 toward the stamping area 102. When the upper slide seat 2 moves toward the stamping area 102, the first guide roller 223 moves against the guide slope, and the movement resistance of the longitudinal cutting seat 22 is significantly reduced by converting sliding friction into rolling friction.

[0057] As attached Figure 4 and 5As shown, the second pressing plate 5 is placed flat and fixed on the placement area 101 of the frame 1. A baffle 51 is also fixed below one end of the frame 1 near the placement area 101. Figure 10 and 15 , support rails 311 are fixed on both sides of the baffle 51 in the frame 1. The support rails 311 are parallel to the slide rails 211. The two support rails 311 are used to support both sides of the lower slide 3, so that the lower slide 3 can slide linearly relative to the placement area 101 and the stamping area 102 along the support rails 311. When the lower slide 3 is supported by the support rails 311, the lower slide 3 is closer to the baffle 51 relative to the upper slide 2. Figure 11 The supporting rail 311 is L-shaped, and the second connecting members 33 are fixed at both ends of the lower slide 3. The second connecting members 33 are connected to the rotatable second roller 312. The second roller 312 is located on the horizontal plane of the supporting rail 311 and rolls. This structure simultaneously ensures the translation stability and smooth operation of the lower slide 3.

[0058] It is worth mentioning that when the upper slide 2 slides to the stamping area 102 and the first pressure plate 4 performs a vertical downward pressing action corresponding to the longitudinal cutting seat 22, after the rubber block is squeezed and cut into strips of rubber, since the lower slide 3 is in front of the upper slide 2, the guide plate 12 can form a guiding role, supporting one end of the strip of rubber cut by the longitudinal cutting seat 22, and guiding the strip of rubber to naturally slide into the cross-cutting seat 32, thereby preventing the strip of rubber from falling to the ground.

[0059] Continue to refer to the attached Figure 10 and 15 A cross-cutting seat 32 is fixed to the lower slide 3. This seat contains an array of equally spaced second cutters 321. These second cutters 321 are also strip-shaped blades with their cutting edges facing upward. The cutters in the cross-cutting seat 32 and the cutters in the longitudinal cutting seat 22 are arranged in an orthographically staggered arrangement. When the rubber block is squeezed in the stamping area 102 by the first pressing plate 4 and the array of first cutters 221 in the longitudinal cutting seat 22, the resulting rubber strips pass through the gaps between the first cutters 221 and fall onto the cross-cutting seat 32. There, they naturally lay horizontally on the array of second cutters 321 in the cross-cutting seat 32 (i.e., the length of the rubber strips is perpendicular to the length of the blades of the second cutters 321). This unique blanking posture, combined with the upward-facing design of the second cutters 321, allows the subsequent lifting of the lower slide 3 to the second pressing plate 5, precisely squeezing and shearing the rubber strips resting on the blades of the second cutters 321, thereby efficiently converting the rubber strips into the desired fine particles. Therefore, the staggered design of the cutters ensures that the strip rubber can be subjected to secondary cross-cutting in the best stress posture (transversely spanning multiple second cutters 321), which is the decisive factor in achieving the completion of longitudinal and transverse cutting in a single drive stroke and ultimately obtaining fine and regular granular products.

[0060] Continue to refer to the attached Figure 10 and15 The upper slide 2 and the lower slide 3 are connected by a set of parallel connecting rods 65 to realize motion coupling and lift the lower slide 3. Specifically, the two ends of each connecting rod 65 are respectively connected to the side wall of the upper slide 2 and the side wall of the lower slide 3 through a pivot to form a rotation pair. Figure 11 As shown, both sides of the upper slide 2 are fixed and extend downward to the first connecting member 25 in the frame 1, and the two 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 slide 2 is displaced toward the placement area 101 by the driving force, the lower slide 3 is forced to move laterally synchronously through the transmission of the connecting rod 65 until the lower slide 3 contacts the baffle 51 to form a mechanical limit. At this time, the upper slide 2 continues to displace, and the lower slide 3 is vertically lifted along the guide surface of the baffle 51 through the geometric constraint of the connecting rod 65, and finally the cross-cutting seat 32 is abutted against the lower surface of the second pressure plate 5, so that each rubber block on the cross-cutting seat 32 is squeezed and cut by the second cutter 321 of the cross-cutting seat 32 and the second pressure plate 5. Refer to the attached Figure 4 A second guide roller 34 is provided on the side of the lower slide 3 facing the baffle 51. The lower slide 3 contacts the baffle 51 through the second guide roller 34 and is vertically lifted along the baffle 51. The movement resistance of the lower slide 3 is significantly reduced by converting sliding friction into rolling friction.

[0061] In addition, the apparatus of the present invention may further include a conveyor belt, one end of which is located within the frame 1 and below the second pressing plate 5, so that the granular rubber squeezed and cut by the second cutter 321 of the cross-cutting seat 32 and the second pressing plate 5 can fall onto the conveyor belt between the two adjacent second cutters 321 of the cross-cutting seat 32 and be directly output from the frame 1 via the conveyor belt, thereby facilitating the collection of the cut and crushed granular rubber.

[0062] The rubber block is pushed from the upper slide 2 into the longitudinal cutting seat 22 to prepare for cutting operation. The specific cutting operation process is as follows:

[0063] The drive cylinder 7 is activated to execute the extension command of the telescopic rod 71, causing the telescopic rod 71 to drive the first pressure plate 4 downward. 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. The strip hole 634 of the transmission arm 631 constrains the contour of the transmission wheel 62, pulling its displacement, converting the rotational motion into linear displacement, and driving the upper slide 2 to slide precisely toward the stamping area 102. When the upper slide 2 slides to the corresponding position under the first pressure plate 4, the first pressure plate 4 continues to apply downward pressure, forcing the array of first cutters 221 inside the longitudinal cutting seat 22 to perform orthogonal cutting on the rubber block. The resulting continuous strip of rubber passes through the gap between the first cutters 221 and falls to the supporting surface of the longitudinal cutting seat 22 of the lower seat 3, completing a cutting process.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
