Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, and in particular to a rubber sheet production system. Background Technology

[0002] Tire waste disposal is a major challenge in environmental protection. my country generates a massive amount of tire waste annually. Direct combustion causes severe environmental pollution, while deep burial lacks sufficient land and tires are slow to degrade, further polluting the soil. Transporting tires to power plants for electricity generation is another option, but its efficiency is very low. Tires can also be used as roadbeds, by laying a layer of tires and then filling the inside and between the tires with gravel. A better approach is to recycle the rubber for use in other rubber products.

[0003] In the rubber recycling process, the extruded rubber strips are usually cooled first, then water-cooled, and then cut into blocks of specified sizes. The blocks are then neatly arranged using packaging and stacking equipment.

[0004] In the prior art, for example, Chinese utility model patent with authorization announcement number "CN220095454U" discloses a production equipment for recycled rubber belts from waste tires, which includes a cooling device, a water cooling device, a cutting device, a packaging device, and a stacking device arranged in sequence; the cooling device includes a conveyor frame, a fumigation mechanism, and an air supply mechanism; the water cooling device includes a cooling tank, a support frame, and a conveying mechanism, and the front and rear ends of the cooling tank are provided with pressing mechanisms; the cutting device includes a conveyor, a mounting frame, a cutting mechanism, and a drive unit; the cutting mechanism includes a connecting base plate, a telescopic elastic blade holder, and a cutting blade mounted on the telescopic elastic blade holder.

[0005] However, when the aforementioned "waste tire recycled rubber belt production equipment" is actually used on the production site, it can only meet the fixed-length cutting and subsequent processing of short rubber sheets. When the production demand changes to long, layered rubber sheets, in order to adapt to the long material process, it is often necessary to stop production and make significant adjustments or even rearrangements to the fixed workstations such as the cutting device, resulting in low production efficiency and insufficient flexibility. Summary of the Invention

[0006] In view of this, it is necessary to provide a rubber sheet production system that can flexibly produce both short and long laminated rubber sheets, and can switch between the two production modes without stopping production due to the adjustment of fixed workstations, thereby improving the production efficiency of rubber sheets.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] This utility model provides a rubber sheet production system, including a folding and cooling device and a stacking device arranged sequentially along the flow direction of the rubber belt;

[0009] The folding and cooling device includes a support frame and an infeed conveying assembly, a folding conveying assembly, a first discharge conveying assembly, a second discharge conveying assembly, and an air supply assembly mounted on the support frame. The infeed conveying assembly is located at the inlet end of the support frame, and the folding conveying assembly is disposed inside the support frame. The first discharge conveying assembly and the second discharge conveying assembly are arranged side by side at the outlet end of the support frame, with the first discharge conveying assembly located above the second discharge conveying assembly. The air supply assembly is installed on the side of the support frame. The infeed conveying assembly is used to... The received rubber belt falls to the folding and conveying assembly, which is used to receive the rubber belt from the feed conveying assembly at intervals and convey the rubber belt to the discharge end of the support frame. The air supply assembly is used to blow cooling airflow onto the rubber belt on the folding and conveying assembly. Both the first discharge conveying assembly and the second discharge conveying assembly are used to receive the rubber belt from the folding and conveying assembly. The first discharge conveying assembly conveys the received rubber belt to the cutting device for fixed-length cutting, and the second discharge conveying assembly allows the received rubber belt to fall naturally.

[0010] The stacking device is disposed below the second discharge conveying assembly. The stacking device is connected to the support frame. The stacking device reciprocates to receive the rubber belt hanging from the second discharge conveying assembly to form a stacked rubber sheet.

[0011] Preferably, the feeding and conveying assembly includes a feeding platform, a first support roller, a pressing roller, a second support roller, a third support roller, and a conveyor belt. The fixed end of the feeding platform is fixedly connected to the middle of the support frame. The first support roller is rotatably connected to the free end of the feeding platform. The second support roller is rotatably connected to the fixed end of the feeding platform. The third roller is rotatably connected to the top of the support frame. The conveyor belt wraps around the first support roller, the second support roller, and the third support roller to form a closed loop. The pressing roller is rotatably connected to the middle of the feeding platform and presses down on the upper surface of the conveyor belt so that the conveyor belt between the first support roller and the pressing roller forms a flat conveying plane.

[0012] Preferably, the folding and conveying assembly includes an upper sprocket shaft group and a lower sprocket shaft group, two first transmission chains, and several receiving frames. The upper sprocket shaft group and the lower sprocket shaft group are arranged parallel to each other on the upper and lower parts of the support frame. The two first transmission chains respectively wrap around the two ends of the upper sprocket shaft group and the lower sprocket shaft group to form a closed loop. The several receiving frames are spaced apart on the first transmission chains. The two ends of the receiving frames are fixedly connected to the two first transmission chains. The receiving frames circulate with the first transmission chains between the upper sprocket shaft group and the lower sprocket shaft group, so that the receiving frames intermittently and repeatedly receive the rubber belt from the feeding conveying assembly and convey the rubber belt to the discharge end of the support frame.

[0013] Preferably, the upper sprocket shaft assembly and the lower sprocket shaft assembly are arranged in a parallelogram so that the first transmission chain forms an inclined buffer section between the upper sprocket shaft assembly and the lower sprocket shaft assembly.

[0014] Preferably, the upper surface of the receiving frame has an anti-slip element, which is used to prevent the rubber strip from sliding relative to the receiving frame.

[0015] Preferably, the air supply assembly includes a guide shroud, a first drive motor, and an impeller. The guide shroud is installed on the side wall of the support frame, and the air outlet of the guide shroud faces the rubber belt on the folding and conveying assembly. The first drive motor and the impeller are both disposed inside the guide shroud, and the output end of the first drive motor is connected to the shaft of the impeller, so that the first drive motor drives the impeller to rotate and generate cooling airflow to blow the rubber belt.

[0016] Preferably, the stacking device includes a first telescopic member and a holding platform. The first telescopic member is installed on the side of the holding platform near the support frame, and the output end of the first telescopic member is detachably connected to the support frame. The first telescopic member drives the holding platform to reciprocate horizontally. The holding platform receives the rubber belt that falls from the second discharge conveying component, so that the rubber belt is stacked to form a stacked rubber sheet.

[0017] Preferably, the rubber sheet production system further includes a cleaning device, which is arranged in front of the folding and cooling device along the flow direction of the rubber belt. The cleaning device includes a cleaning tank and a traction assembly. The cleaning tank is divided into a cooling tank and a degumming tank. The traction assembly is arranged across the top of the cleaning tank and is located between the cooling tank and the degumming tank. The middle part of the rubber belt is immersed in the cooling tank, and one end of the rubber belt passes through the traction assembly. The traction assembly pulls the rubber belt immersed in the cooling tank into the degumming tank so that the surface stickiness of the rubber belt can be removed by the chemical solution contained in the degumming tank. The feeding conveyor assembly receives the rubber belt from the degumming tank.

[0018] Preferably, the traction assembly includes a lower roller, an upper roller, a lifting part, and a driving part. The two ends of the lower roller are rotatably connected to the inner walls of both sides of the washing tank. The lifting part is located directly above the lower roller, and its bottom is rotatably connected to both ends of the upper roller, so that a traction space is formed between the circumferential surface of the upper roller and the lower circumferential surface of the lower roller. The lifting part drives the upper roller to rise or fall to adjust the height of the traction space formed by the upper roller and the lower roller to accommodate rubber belts of different thicknesses. The driving part is located on the side of the lower roller, and its output end is connected to the lower roller. The driving part drives the lower roller to rotate.

[0019] Preferably, the lifting unit includes a support frame, a lifting roller frame, and a second telescopic member. The support frame and the lifting roller frame are both located directly above the lower roller, and the lifting roller frame is located between the support frame and the lower roller.

The output end of the second telescopic member passes through the support frame and is connected to the top of the lifting roller frame. Both ends of the lifting roller frame are rotatably connected to both ends of the upper roller. The second telescopic member drives the lifting roller frame to rise or fall, and the lifting roller frame drives the upper roller to rise or fall.

[0020] As can be seen from the above technical solution, the rubber sheet production system provided by this utility model, when producing rubber sheets, firstly uses a folding and conveying assembly to fold and unfold the rubber belt at intervals and reciprocatingly, thereby integrating and accommodating a longer rubber belt within a limited space. This not only facilitates efficient and uniform cooling of the rubber belt by the air supply assembly in the interval and reciprocating folding state, but also significantly increases the heat dissipation area per unit area, improving the cooling efficiency. Subsequently, a dual-output system is constructed by using a first discharge conveying assembly and a second discharge conveying assembly arranged in parallel at the discharge end of the support frame. Specifically, the first discharge conveyor guides the rubber belt to the subsequent fixed-length cutting process to produce standard-sized short sheets. The second discharge conveyor causes the rubber belt to fall directly from top to bottom onto the stacking device below. The stacking device then repeatedly receives the rubber belt falling from the second discharge conveyor, and after natural stacking, it forms a stacked rubber sheet. This allows for flexible adaptation to production needs, enabling rapid switching between the two production modes of "short material fixed-length cutting" and "long material stacking" without stopping the machine for adjustments, greatly improving equipment utilization and production efficiency.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please refer to Figures 1 to 6 The present invention provides a rubber sheet production system 10, which includes a folding and cooling device 110 and a stacking device 120 arranged sequentially along the flow direction of the rubber belt.

[0031] The folding and cooling device 110 includes a support frame 111 and a feeding conveying assembly 112, a folding and cooling conveying assembly 113, a first discharging conveying assembly 114, a second discharging conveying assembly 115, and an air supply assembly 116 mounted on the support frame 111. The feeding conveying assembly 112 is located at the feeding end of the support frame 111, the folding and cooling conveying assembly 113 is located inside the support frame 111, the first discharging conveying assembly 114 and the second discharging conveying assembly 115 are arranged side by side at the discharging end of the support frame 111, and the first discharging conveying assembly 114 is located above the second discharging conveying assembly 115. The air supply assembly 116 is mounted on the side of the support frame 111. The material conveying assembly 112 is used to drop the received rubber belt onto the folding conveying assembly 113. The folding conveying assembly 113 is used to reciprocate to receive the rubber belt from the feed conveying assembly 112 and convey the rubber belt to the discharge end of the support frame 111. The air supply assembly 116 is used to blow cooling airflow onto the rubber belt on the folding conveying assembly 113. The first discharge conveying assembly 114 and the second discharge conveying assembly 115 are both used to receive the rubber belt from the folding conveying assembly 113. The first discharge conveying assembly 114 conveys the received rubber belt to the cutting device for fixed-length cutting, and the second discharge conveying assembly 115 allows the received rubber belt to drop naturally.

[0032] The stacking device 120 is located below the second discharge conveying assembly 115. The stacking device 120 is connected to the support frame 111. The stacking device 120 reciprocates to receive the rubber belt hanging from the second discharge conveying assembly 115 to form a stacked rubber sheet.

[0033] In the production of rubber sheets, the rubber belt is first folded and reciprocated at intervals by the folding and conveying assembly 113, thereby integrating and accommodating a longer rubber belt within a limited space. This not only facilitates efficient and uniform cooling of the rubber belt by the air supply assembly 116 in the folded and reciprocated state, but also significantly increases the heat dissipation area per unit area, improving cooling efficiency. Subsequently, a dual-output mode is constructed by the first discharge conveying assembly 114 and the second discharge conveying assembly 115 arranged in parallel at the discharge end of the support frame 111. Specifically, the first discharge conveying assembly... Part 114 guides the rubber belt to the subsequent fixed-length cutting process to produce standard-sized short sheets. The second discharge conveyor assembly 115 causes the rubber belt to fall directly from top to bottom onto the stacking device 120 below. The stacking device 120 then repeatedly receives the rubber belt falling from the second discharge conveyor assembly 115, and after natural stacking, it forms a stacked rubber sheet. This allows for flexible adaptation to production needs, and the machine can be quickly switched between the two production modes of "short material fixed-length cutting" and "long material stacking" without stopping for adjustments, greatly improving equipment utilization and production efficiency.

[0034] Furthermore, to remove residual heat and surface stickiness of the rubber belt after extrusion molding, and to produce a cooled, shaped, dry, and non-sticky rubber belt, providing a suitable material base for subsequent conveying and stacking, the rubber sheet production system 10 also includes a cleaning device 130. The cleaning device 130 is positioned in front of the folding and cooling device 110 along the rubber belt flow direction. The cleaning device 130 includes a cleaning tank 131 and a traction assembly 132. The cleaning tank 131 is divided into a cooling tank 1311 and a degumming tank 1312. The traction assembly 132 is positioned transversely above the cleaning tank 131, and the traction assembly 132 is positioned... Between the cooling tank 1311 and the de-adhesive tank 1312, during use, the middle part of the rubber belt is immersed in the cooling tank 1311, and one end of the rubber belt is inserted into the traction assembly 132. The traction assembly 132 pulls the rubber belt immersed in the cooling tank 1311 into the de-adhesive tank 1312. The feeding conveying assembly 112 receives the rubber belt from the de-adhesive tank 1312, causing the rubber belt to pass through the cooling tank 1311 and the de-adhesive tank 1312 in sequence. The surface stickiness of the rubber belt is removed by the chemical solution contained in the de-adhesive tank 1312, which fundamentally prevents the phenomenon of mutual adhesion during the conveying and stacking process.

[0035] Furthermore, to ensure that the traction assembly 132 can traction rubber belts of different thicknesses and effectively improve the process compatibility of the production system with rubber belts of various specifications, the traction assembly 132 includes a lower roller 1321, an upper roller 1322, a lifting part 1323, and a drive part 1324. The two ends of the lower roller 1321 are rotatably connected to the inner walls of both sides of the washing tank 131. The lifting part 1323 is located directly above the lower roller 1321, and its bottom is rotatably connected to both ends of the upper roller 1322, so that a traction space is formed between the circumferential surface of the upper roller 1322 and the lower circumferential surface of the lower roller 1321. When tractioning the rubber belt, one side of the rubber belt... The upper roller 1322 and the lower roller 1321 are inserted into the traction space formed between the upper roller 1322 and the lower roller 1321. The lifting part 1323 drives the upper roller 1322 to rise or fall, so as to adjust the height of the traction space formed by the upper roller 1322 and the lower roller 1321, so as to make the upper roller 1322 and the lower roller 1321 bite the rubber belt together. The driving part 1324 is provided on the side of the lower roller 1321. The output end of the driving part 1324 is connected to the lower roller 1321. The driving part 1324 drives the lower roller 1321 to rotate, and then the rubber belt is pulled into the glue removal groove 1312 by the friction between the upper roller 1322, the lower roller 1321 and the rubber belt.

[0036] Furthermore, the lifting unit 1323 includes a support frame 13231, a lifting roller frame 13232, and a second telescopic member 13233. The support frame 13231 and the lifting roller frame 13232 are both located directly above the lower roller 1321, and the lifting roller frame 13232 is located between the support frame 13231 and the lower roller 1321. The second telescopic member 13233 is disposed on the top of the support frame 13231. The two ends of the support frame 13231 are fixedly connected to the upper walls on both sides of the washing pool 131, respectively. The output end of the second telescopic member 13233 passes through the support frame 13231 and is connected to the top of the lifting roller frame 13232. The two ends of the lifting roller frame 13232 are rotatably connected to the two ends of the upper roller 1322, respectively. The second telescopic member 13233 drives the lifting roller frame 13232 to rise or fall, and the lifting roller frame 13232 drives the upper roller 1322 to rise or fall.

[0037] In a preferred embodiment, the drive unit 1324 includes a second drive motor 13241, a drive sprocket 13242, a driven sprocket 13243, and a second transmission chain 13244. The second drive motor 13241 is detachably mounted on the side wall of the support frame 13231 by bolts. The drive sprocket 13242 is mounted on the output shaft of the second drive motor 13241. The driven sprocket 13243 is mounted on the end of the lower roller 1321. The second transmission chain 13244 surrounds the drive sprocket 13242 and the driven sprocket 13243. The second drive motor 13241 drives the lower roller 1321 to rotate through the second transmission chain 13244.

[0038] In a preferred embodiment, there may be three lower rollers 1321, which are arranged horizontally side by side. A driven sprocket 13243 is mounted on the same end shaft of each of the three lower rollers 1321. Adjacent driven sprockets 13243 are connected by chains. A second transmission chain 13244 is connected to the driven sprocket 13243 at the shaft end of one of the lower rollers 1321 directly below the second drive motor 13241. When the second drive motor 13241 starts, power is transmitted through the second transmission chain. The strip 13244 is synchronously transmitted to the three lower rollers 1321, ensuring that the three lower rollers 1321 rotate together. The lower circumferential surface of the middle lower roller 1321 and the upper circumferential surface of the upper roller 1322 form a traction space. The lower rollers 1321 on both sides provide a continuous support surface for the traction space formed by the upper roller 1322 and the middle lower roller 1321, thereby jointly constraining the posture of the rubber belt, increasing the contact area between the lower rollers 1321 and the rubber belt, and ensuring the smoothness of the traction process.

[0039] In a preferred embodiment, limiting members 1313 are symmetrically arranged on the inner walls of opposite sides of the cooling tank 1311, and the limiting members 1313 are located at one end of the cooling tank 1311 near the traction assembly 132. The limiting members 1313 are used to clamp the guide rubber belt from both sides to prevent deviation due to the large width of the rubber belt or floating in the liquid.

[0040] The limiting component 1313 includes an L-shaped support rod 13131 and a rotating drum 13132. The fixed end of the L-shaped support rod 13131 is fixedly connected to the inner wall of the cooling tank 1311. The rotating drum 13132 is rotatably sleeved on the free end of the L-shaped support rod 13131 through a bearing, so that the rotating drum 13132 can rotate freely around the L-shaped support rod 13131. During operation, the two sides of the rubber belt contact the circumference of the rotating drum 13132 in the limiting components 1313 on both sides. During the process of the rubber belt being pulled, the rotating drums 13132 on both sides together form a guide channel, which can effectively constrain the lateral movement of the rubber belt and ensure that it always moves in a straight line along the preset path, avoiding problems such as jamming or collision with the tank wall caused by deviation, thereby ensuring the uniformity of the cooling process and the continuity of production operation.

[0041] Similarly, limiters 1313 are symmetrically arranged on the inner walls of opposite sides of the glue removal tank 1312 to prevent the rubber belt from deviating in the glue removal tank 1312, ensure that the contact time and reaction degree between the rubber belt surface and the chemical solution are consistent, and avoid uneven glue removal effect.

[0042] Furthermore, the feeding conveying assembly 112 includes a feeding platform 1121, a first support roller 1122, a pressing roller 1123, a second support roller 1124, a third support roller 1125, and a conveyor belt 1126. The fixed end of the feeding platform 1121 is fixedly connected to the middle of the support frame 111, and the free end of the feeding platform 1121 extends above the discharge end of the degumming tank 1312. The first support roller 1122 is rotatably connected to the free end of the feeding platform 1121, and the second support roller 1123 is rotatably connected to the free end of the feeding platform 1121. 124 is rotatably connected to the fixed end of the feeding platform 1121. The third roller is rotatably connected to the top of the support frame 111. The conveyor belt 1126 forms a closed loop around the first support roller 1122, the second support roller 1124, and the third support roller 1125. The pressing roller 1123 is rotatably connected to the middle of the feeding platform 1121. The pressing roller 1123 presses down on the upper surface of the conveyor belt 1126, so that the conveyor belt 1126 between the first support roller 1122 and the pressing roller 1123... 126 forms a flat conveying plane. During operation, the rubber belt, after being treated by the degumming trough 1312, is led out from the discharge end of the trough and guided into the conveying plane between the first support roller 1122 and the pressing roller 1123. The first support roller 1122, the pressing roller 1123, the second support roller 1124, and the third support roller 1125 are driven to rotate by a motor, causing the conveyor belt 1126 to support the rubber belt, passing it under the pressing roller 1123 and conveying it naturally towards the top of the support frame 111. The conveyor belt 1126 is dropped and squeezed by the pressure roller 1123, which effectively eliminates the wrinkles and arches of the rubber belt. At the same time, it squeezes out the liquid remaining on the surface of the rubber belt for preliminary dehydration, ensuring that the rubber belt is smoothly guided to the top of the support frame 111. The material of the conveyor belt 1126 can be thermoplastic polyurethane with elasticity and high traction friction, or chemically resistant synthetic rubber, etc. Its working surface can be designed with fine patterns to further enhance the traction capacity, while ensuring that there is no harmful adhesion to the rubber belt after the de-adhesion treatment.

[0043] Furthermore, the folding and conveying assembly 113 includes an upper sprocket shaft assembly 1131 and a lower sprocket shaft assembly 1132, two first transmission chains 1133, and several receiving frames 1134. The upper sprocket shaft assembly 1131 and the lower sprocket shaft assembly 1132 are arranged parallel to each other on the upper and lower parts of the support frame 111. The two first transmission chains 1133 respectively wrap around the two ends of the upper sprocket shaft assembly 1131 and the lower sprocket shaft assembly 1132 to form a closed loop. Several receiving frames 1134 are spaced apart on the first transmission chains 1133. The two ends of the receiving frames 1134 are fixedly connected to the two first transmission chains 1133 respectively. The receiving frames 1134 move with the first transmission chains 1133 between the upper sprocket shaft assembly 1131 and the lower sprocket shaft assembly 1132. The cyclic operation allows the receiving frame 1134 to reciprocate at intervals to receive the rubber belt from the feed conveying assembly 112 and transport the rubber belt to the discharge end of the support frame 111. During operation, the end of the rubber belt from the feed conveying assembly 112 falls naturally between the two first transmission chains 1133 under the action of gravity. The upper sprocket shaft group 1131 or the lower sprocket shaft group 1132 is slowly driven by the motor to rotate, which drives the two first transmission chains 1133 and the several receiving frames 1134 arranged at intervals on them to run synchronously. After each receiving frame 1134 receives a section of rubber belt, it moves with the first transmission chain 1133 toward the discharge end of the support frame 111. During this process, the adjacent receiving frames 1134 achieve a regular folding and unfolding.

[0044] Furthermore, the upper sprocket shaft assembly 1131 and the lower sprocket shaft assembly 1132 are arranged in a parallelogram so that the first transmission chain 1133 forms an inclined buffer section between the upper sprocket shaft assembly 1131 and the lower sprocket shaft assembly 1132. This ensures that the rubber belt has enough time and space to fall naturally under its own weight when it is folded, increasing the effective length of a single folding. This allows for the integration of a longer rubber belt within a limited space, improving space utilization and the processing capacity of a single batch.

[0045] Furthermore, the upper surface of the receiving frame 1134 has an anti-slip element 1135, which is used to prevent the rubber belt from sliding relative to the receiving frame 1134 and to ensure the regularity of the rubber belt folding.

[0046] In a preferred embodiment, the anti-slip component 1135 can be a bolt, with its stud portion screwed into and fixed in a pre-set threaded hole on the upper surface of the receiving frame 1134, and the head of the bolt protruding from the surface of the frame as an anti-slip protrusion.

[0047] Furthermore, the air supply assembly 116 includes a guide shroud 1161, a first drive motor 1162, and an impeller 1163. The guide shroud 1161 is mounted on the side wall of the support frame 111, and the air outlet of the guide shroud 1161 faces the rubber belt on the folding and conveying assembly 113. The first drive motor 1162 and the impeller 1163 are both disposed inside the guide shroud 1161, and the output end of the first drive motor 1162 is connected to the shaft of the impeller 1163, so that the first drive motor 1162 drives the impeller 1163 to rotate and generate cooling airflow to blow the rubber belt.

[0048] In a preferred embodiment, the air supply components 116 are configured in several groups and are evenly distributed in an array manner on the top of the support frame 111 and at least one side.

[0049] Furthermore, the stacking device 120 includes a first telescopic member 121 and a holding platform 122. The first telescopic member 121 is detachably mounted on the holding platform 122 near the support frame 111 by bolts, and the output end of the first telescopic member 121 is detachably connected to the support frame 111 by a pin. The first telescopic member 121 drives the holding platform 122 to reciprocate horizontally. The holding platform 122 receives the rubber belt hanging from the second discharge conveying assembly 115, so that the rubber belt is stacked to form a stacked rubber sheet. Specifically, the long rubber belt output by the second discharge conveying assembly 115... Under its own gravity, the rubber belt falls naturally. At this time, the first telescopic component 121 is activated, driving the holding platform 122 to perform horizontal reciprocating motion. Its movement rhythm matches the falling rhythm of the rubber belt. When a section of the rubber belt falls, the holding platform 122 moves to its direct below to receive it. Then, the holding platform 122 moves horizontally a distance under the drive of the first telescopic component 121. Immediately afterward, the next section of the rubber belt falls and is stacked on top of the previous section. This process is repeated, and the rubber belts are stacked regularly and alternately on the holding platform 122, automatically forming a neat and tight layered rubber sheet.

[0050] In a preferred embodiment, four casters are provided at the four corners of the bottom of the holding platform 122 so that the holding platform 122 can move freely on the ground, making it easy to quickly adjust its relative position with the support frame 111 according to production needs, or to move it out of the workstation for replacement.

[0051] Specifically, when it is necessary to switch between the two production modes of "short material fixed length cutting" and "long material stacking" of this utility model, the operator only needs to move the receiving frame 1134 to the rubber belt guide end of the support frame 111 discharge end, and manually guide it into the first discharge conveying component 114 or the second discharge conveying component 115 to complete the mode switching.

[0052] In this utility model, the first telescopic member 121 and the second telescopic member 13233 can both be telescopic cylinders, and the first discharge conveying assembly 114 and the second discharge conveying assembly 115 can both be belt conveyors commonly used in the prior art.

[0053] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
