Description

Technical Field

[0001] This invention relates to the field of rubber processing technology, and in particular to a high-efficiency cutting device and its cutting method. Background Technology

[0002] In the manufacturing industry of elastomers such as rubber, silicone, and polyurethane, products typically undergo mixing and molding processes (such as compression molding and injection molding) to form semi-finished products with main runners, branch runners, and flash. These excess rubber materials (sprues) must be removed precisely and efficiently to obtain finished parts that meet design requirements. Therefore, the cutting process is a crucial part of rubber post-processing.

[0003] Traditional cutting devices can usually only cut single products or specific sizes, especially with dedicated molds and fixed cutting machines (such as a sponge cutting machine disclosed in patent CN215093905U). Once the product specifications change, the molds and fixtures need to be replaced or readjusted, which is cumbersome, time-consuming and costly. Although traditional mechanical cutting is slightly faster, manual operation is still required for loading and unloading, resulting in a low level of automation and making it inconvenient for continuous production. For circular or arc-shaped cutting requirements, traditional cutting devices are not suitable for achieving perfect circular or arc-shaped cuts. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-efficiency cutting device and its cutting method, achieving good versatility and high cutting efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A high-efficiency cutting device includes a processing table and a cutting head for cutting rubber products, a gantry frame, an adjustment component for adjusting the position of the cutting head, and a limiting component for positioning the rubber products. The cutting head is mounted on the top of the gantry frame via the adjustment component, and the limiting component consists of a pair of clamping structures arranged opposite each other, with the clamping structures corresponding to the sides of the gantry frame.

[0006] Further or preferred: The processing table is equipped with a set of rollers and a motor for driving the rollers, and a conveyor belt is provided on the processing table corresponding to the rollers.

[0007] The top of the processing table is a flat plate, and the rollers are embedded in the flat plate.

The electric push rod is located above the top of the gantry frame, the disc is located inside the gantry frame, the center of the disc is connected to the lower end of the electric push rod through the motor V, and the cutter head is located on the disc.

[0009] The disc has a radial groove, and a movable slider is provided in the groove. The cutter head is located below the slider via a motor IV.

[0010] The slide groove is equipped with a lead screw, and the outer edge of the disc is equipped with a motor III for driving the lead screw. The lead screw cooperates with the slider.

[0011] The inner side of the gantry frame is provided with a heating structure for heating the adhesive.

[0012] The limiting assembly includes a motor II, a pair of support seats, a pair of clamping plates, and a bidirectional screw. The top of the processing table is provided with a guide groove in the horizontal direction. The bidirectional screw is located in the guide groove. The motor II is located on the side of the processing table and connected to the end of the bidirectional screw. The guide groove is provided with a sliding block that cooperates with the bidirectional screw. The support seats are connected to the sliding blocks. The clamping plates are located inside the corresponding support seats.

[0013] The inner side of the clamp is provided with a contour groove that matches the outline of the rubber product.

[0014] A cutting method for cutting rubber products using the above-mentioned high-efficiency cutting device includes the following steps: S1. First, adjust the position of the cutter head by adjusting the size of the rubber product to be circumferentially cut as needed; S2. The rubber products to be cut and processed are conveyed until they are transported to the position below the gantry frame, where they are clamped and positioned by the limiting components. S3.

The blade position can be flexibly adjusted, and while cutting efficiently, it can cut rubber products into different sizes, making it highly versatile. A limiting structure for positioning the rubber products is provided above the processing table, which can ensure the stability of the rubber product cutting process.

These relative terms are for ease of description and are not generally intended to require a specific direction.

[0026] The purpose of this invention is to provide a high-efficiency cutting device and method for rubber products after molding, so as to solve the problems of poor versatility, insufficient flexibility, low cutting efficiency, low degree of automation, and difficulty in realizing complex cutting paths mentioned in the background art.

[0027] like Figures 1 to 5As shown, the high-efficiency cutting device for the formed rubber product includes a processing table, a cutting head for cutting the rubber product, a gantry frame, an adjustment component for adjusting the position of the cutting head, and a limiting component for positioning the rubber product.

[0028] The drive structure drives the disc and cutter head to cut the rubber product. The position of the cutter head can be adjusted by the adjustment component, and the rubber product is positioned by the limiting component. In other words, the position of the cutter head can be flexibly adjusted, and the rubber product can be cut into different sizes while maintaining high cutting efficiency, which is very versatile. The limit structure above the processing table is equipped with a rubber product positioning structure to ensure the stability of the rubber product cutting process. The integrated conveyor belt and roller conveyor effectively improve the cutting and processing efficiency.

[0029] The processing table includes a platform and a set of columns. The set of columns is set vertically to support the platform. The top of the columns is welded to the bottom of the platform or connected by fasteners, making the structure stable and reliable. Alternatively, the set of columns can be connected by connecting beams to form a frame structure, and the platform is set on the frame structure.

[0030] The gantry frame is set on the platform, that is, the lower end of the gantry frame is welded to the corresponding side of the platform or connected by fasteners. The two are integrated to form an integral device structure, which is convenient for layout and installation in the workshop; or, the gantry frame is set up separately, spanning the platform, and the side frame of the gantry frame is directly fixed to the ground. The side frame and the side of the platform are positioned by a positioning structure. Preferably, the positioning structure is a convex-concave mating structure, with a side boss on the side of the platform and a groove on the side frame of the gantry frame that matches the side boss. The precise alignment between the gantry frame and the platform is achieved through the mating of the side boss and the groove.

[0031] The gantry frame includes a pair of side frames and a top beam located between the top of the pair of side frames; the cutter head is located on the top of the gantry frame via an adjustment assembly, and the cutter head is located below the top beam of the gantry frame. The height of the cutter head and its position relative to the disc are adjusted by the adjustment assembly to meet the cutting needs of different specifications of rubber products. The limiting components consist of a pair of clamping structures positioned opposite each other. These clamping structures are located on the side of the gantry frame. The relative movement of the pair of clamping structures clamps and limits the plastic product, ensuring product stability and reliability during the cutting process. The inner side of the gantry frame is equipped with a distance sensor or vision module to detect the position of the plastic product and automatically control the movement of the clamping structures to clamp the plastic product, effectively improving processing efficiency.

[0032] The side frames of the gantry are vertically arranged side plates, and the top beam of the gantry is a horizontally arranged top plate. The top plate is located between the tops of a pair of side plates. The top plate is equipped with an electric push rod for easy installation of the adjustment components, and the structure is stable and reliable.

[0033] The adjustment assembly includes an electric push rod, a disc, and a motor V. The electric push rod is fixed above the top plate of the gantry frame, which has a through hole. The lower end of the push rod passes through the through hole and is located inside the gantry frame. The disc is located inside the gantry frame, and the center of the disc is connected to the lower end of the electric push rod via motor V. The cutter head is located on the disc, and the disc can be rotated by motor V. When the electric push rod is working, the height position of the disc and the cutter head can be adjusted.

[0034] The disc has a radial groove, and a movable slider is provided in the groove. The cutter head is located below the slider via motor IV. The position of the cutter head is adjusted by adjusting the position of the slider in the groove, and the cutter head is driven by motor IV to perform cutting work.

[0035] Furthermore, a lead screw is installed inside the slide groove, and the end of the lead screw is set in the slide groove through a bearing. The lead screw can rotate in the slide groove. A motor III is provided on the outer edge of the disc to drive the lead screw. The lead screw cooperates with the slider. The operation of motor III drives the lead screw to rotate, thereby driving the slider to move and adjust in the slide groove, so as to adjust the position of the cutter head.

[0036] The electric actuator can also adopt other lifting structures, such as scissor lift or cylinder lift. The lifting structure drives the lifting platform to adjust its height. The lower part of the lifting platform is equipped with a motor that drives the disc, and the lower part of the disc is equipped with a cutting head.

[0037] The slider position adjustment in the groove of the disc can also be achieved using other drive structures, such as an electric push rod set in the groove. Regardless of the drive structure used, it is integrated into the groove of the disc, resulting in a compact structure that does not affect the cutting operation.

[0038] The processing table has a flat platform structure. The processing table is equipped with a set of rollers and a motor for driving the rollers. A conveyor belt is provided on the processing table corresponding to the rollers. The conveyor belt realizes the conveying of the rubber products. The horizontal conveyor belt conveys the rubber products stably and reliably, which is conducive to the batch and efficient processing of the production line. The top of the processing table is a strip-shaped flat plate, and a group of rollers are equidistantly embedded in the flat plate. The integrated setup is compact and facilitates the formation of a supported conveyor belt structure. like Figure 2 As shown, the end of the strip plate is provided with a notch, and the roller at the end is located in the notch. The motor on the side of the processing table drives the roller at the end to realize the drive of the transmission belt; there is no need to set a transition roller, and the structure is compact.

[0039] The area in front of the gantry frame on the processing table is the loading and conveying area, and the area behind the gantry frame on the processing table is the unloading and conveying area. The loading and unloading areas are the limiting and cutting processing areas. Furthermore, a material adjustment structure is provided in the corresponding feeding and conveying area for adjusting the position of the rubber product; by adjusting the position of the rubber product through the material adjustment structure, the position of the rubber product is aligned with the center position of the transmission belt, that is, the middle position of the limiting structure, to ensure that the limiting structure accurately positions the product.

[0040] The material adjustment structure consists of a pair of adjustment side plates, which are mounted on the processing table above the conveyor belt via a bracket. The pair of adjustment side plates are set with a large front spacing and a small rear spacing to achieve automatic adjustment of the position of the adhesive. Alternatively, the adjustment side plates can be replaced with adjustment side rods, which have low resistance and will not cause jamming.

[0041] Furthermore, the inner side of the gantry frame is equipped with a heating structure for heating the adhesive; the heating structure can use radiant heating or baking heating to increase the temperature of the adhesive, which is conducive to achieving stable cutting work in low temperature conditions.

[0042] The limiting assembly includes motor II, a pair of support seats, a pair of clamping plates, and a bidirectional screw. The top of the processing table is provided with a guide groove, the bidirectional screw is located in the guide groove, motor II is located on the side of the processing table and connected to the end of the bidirectional screw, the guide groove is provided with a sliding block that cooperates with the bidirectional screw, the support seat is connected to the sliding block, and the clamping plate is located inside the corresponding support seat.

[0043] The guide groove consists of two guide grooves arranged side by side. The bidirectional screw is set in one guide groove. The sliding block on the lower front side of the support seat cooperates with the bidirectional screw, and the sliding block on the lower rear side of the support seat is in another guide groove. The support seat moves stably and reliably. The support base is a vertical plate, and the conveyor belt is located between a pair of support bases. There is a gap between the edge of the conveyor belt and the support base, ensuring stable and reliable operation. The outer side of the clamping plate is connected to the top of the support base, and the inner side of the clamping plate forms a suspended structure. There is a gap between the lower surface of the clamping plate and the upper surface of the conveyor belt, ensuring stable and reliable clamping and positioning of the rubber product.

[0044] Furthermore, the inner side of the clamp is provided with a contour groove that matches the shape of the adhesive product, ensuring stable and reliable clamping; the outer side of the clamp is detachably connected to the top of the support base by fasteners, and the corresponding clamp can be replaced with the appropriate clamp for different models of adhesive products.

[0045] Furthermore, a PLC control panel is installed on the outer side of the gantry frame. The PLC control panel is connected to motor I, electric push rod, motor II, motor III, motor IV and motor V respectively to realize integrated control, automate the cutting process and effectively improve the cutting efficiency.

[0046] This invention provides a cutting method for cutting rubber products using the above-mentioned high-efficiency cutting device, comprising the following steps: S1. First, adjust the position of the cutter head by adjusting the size of the rubber product to be circumferentially cut as needed; S2. The rubber products to be cut and processed are conveyed until they are transported to the position below the gantry frame, where they are clamped and positioned by the limiting components. S3. The drive structure drives the disc and cutter head inside the gantry to cut the rubber product.

[0047] This invention features a sliding groove at the bottom of a disc that connects a slider, motor IV, and a cutter head. A lead screw, threadedly connected to the slider, rotates under the drive of motor III, causing the slider and cutter head to move within the groove. This allows for adjustment of the distance between the cutter head and the center of the disc, facilitating adaptation to different processing requirements of various rubber products. An electric push rod drives motor V and the entire disc for height adjustment. Motor IV drives the cutter head to rotate and, under the drive of motor V, performs circumferential cutting of the rubber product. This method offers high-efficiency cutting and can cut the rubber product into different sizes.

[0048] The present invention has symmetrical guide grooves on the top of the processing table. A bidirectional screw is set in one guide groove to connect a symmetrically arranged sliding block, support seat and clamping plate. A sliding rod is set in the other guide groove and is slidably connected to the support seat. The bidirectional screw is driven to rotate by a motor II outside the processing table. The bidirectional screw drives the sliding block, support seat and clamping plate to move closer and clamp the rubber product to ensure stability during the cutting process.

[0049] This invention features equidistant rollers connected to a conveyor belt at the top of a processing table. The rollers at the ends are driven by motor I, which in turn moves the conveyor belt. Placing the rubber product on the conveyor belt surface allows for the gradual loading, cutting, and unloading of the product, increasing the efficiency of the rubber product cutting process. The above control is integrated through PLC control, which is simple to operate and provides stable performance.

[0050] The device of this invention can realize automatic feeding, automatic positioning, automatic cutting and automatic unloading of rubber products; the position of the cutter head is flexibly adjustable and can cut circles / rings of different diameters; the cutting is stable, efficient and suitable for continuous operation of production lines; it can also cut stably in low temperature environments.

[0051] Detailed explanation of the principles of this invention: Processing table (conveying and support system): It consists of a platform, columns, and frame, which are rigid and stable in operation; it has built-in rollers and conveyor belts, driven by motors, to realize continuous automatic conveying of rubber products; the loading area → cutting area → unloading area are integrated, which is suitable for batch processing on the production line; the front end is equipped with a flared adjusting side plate / side rod, which automatically "aligns" the rubber products to the center of the conveyor belt to ensure accurate subsequent positioning.

[0052] Gantry frame (main frame for cutting execution): Composed of two side plates and a top crossbeam, it has high rigidity and provides a stable mounting base for the cutter head; it can be fixed to the platform as a whole or installed on the ground, and is precisely positioned by bosses and grooves; the inner side is equipped with a distance measuring / vision module to automatically identify the position of the adhesive; a heating structure can be selected to soften the adhesive at low temperatures, making the cutting smoother and preventing edge chipping.

[0053] Adjustment components (core of cutter head position adjustment): Top electric push rod / cylinder / scissor fork → controls the overall lifting and lowering of the cutter head to adapt to different heights of rubber products; the lower end of the push rod is connected to motor V + disc → motor V drives the disc to rotate as a whole to achieve a circumferential cutting trajectory; the distance from the cutter head to the center of the circle can be steplessly adjusted, thereby cutting circles / rings of different diameters.

[0054] Limiting components (precise positioning of adhesive products): ensure that the adhesive products do not deviate or vibrate during cutting; when the screw rotates, the two support seats on the left and right and the clamping plates move towards the center synchronously; the clamping plates can be made with contour grooves to fit the shape of the adhesive products; they can be quickly replaced to adapt to different products; a small gap is left between the clamping plates and the conveyor belt to avoid interfering with the conveying process, only clamping and positioning.

[0055] This high-efficiency cutting device for rubber product molding is based on a stable processing table, with rigid support provided by a gantry frame. The bidirectional screw drive of the limiting component synchronously clamps the rubber product, and the material adjustment structure achieves precise positioning. The height of the cutter head and its distance from the center of the disc are flexibly adjusted using the electric push rod, lead screw, and slider of the adjustment component. The motor drives the cutter head to rotate on its own axis and revolve around the disc to complete circumferential cutting. Simultaneously, rollers and conveyor belts enable automatic feeding, cutting, and unloading of the rubber product. The entire system is integrated and controlled by a PLC control panel, ensuring the stability and precision of the cutting process while achieving efficient cutting of rubber products of different sizes. This improves the device's versatility and processing efficiency. In low-temperature environments, a heating structure further ensures cutting stability.

[0056] like Figures 1 to 5 As shown, a preferred embodiment of the present invention is as follows: This embodiment provides a high-efficiency cutting device and cutting method for rubber products after molding, including a processing table 1, a gantry frame 3, a cutter head 18, a limiting component and an adjusting component. The limiting component is installed on the top of the processing table 1, and the adjusting component is installed inside the gantry frame 3. When the adjusting component is started, it adjusts the position of the cutter head 18 to adapt to different processing requirements.

[0057] The rubber product is clamped and limited by the limiting component, and the position of the cutter head 18 is adjusted by the adjusting component. Then, the rubber product is circumferentially cut, which is highly efficient and stable while having a high overall processing efficiency.

[0058] Reference Figures 1 to 5In one embodiment of the present invention, the adjustment assembly specifically includes a disc 14, a lead screw 15, a slider 16, a motor III 17, and a slide groove 20. The gantry 3 has a disc 14 inside, and a slide groove 20 is opened at the bottom of the disc 14. The slider 16 is slidably connected inside the slide groove 20. The lead screw 15 is installed inside the slide groove 20 and is threadedly connected to the slider 16. The motor III 17 is installed on the surface of the disc 14, and the output end of the motor III 17 is connected to the lead screw 15.

[0059] The position of the cutter head 18 is adjusted according to the size of the rubber product to be circumferentially cut. In specific use of this invention, motor III 17 is first started to drive the lead screw 15 to rotate. The lead screw 15 drives the slider 16, motor IV 19 and cutter head 18 to move as a whole in the slide groove 20, so as to precisely adjust the distance from the cutter head 18 to the center of the disc 14.

[0060] Reference Figures 1 to 5 In one embodiment of the present invention, a motor IV 19 is mounted on the bottom of the slider 16, and the output end of the motor IV 19 is connected to the cutter head 18. Driving the cutter head 18 with the motor IV 19 ensures efficient cutting while facilitating overall position adjustment of the motor IV 19 and the cutter head 18, making it easy to adapt to different processing requirements of various adhesives.

[0061] Reference Figure 1 , Figure 4 and Figure 5 In one embodiment of the present invention, an electric push rod 4 is installed on the top of the gantry frame 3. The output end of the electric push rod 4 passes through the gantry frame 3 and is connected to a motor V21. The output end of the motor V21 is connected to the center of the disc 14. The disc 14 is driven to rotate by the motor V21, which in turn drives the motor IV19 to drive the cutter head 18 to perform a circular motion, facilitating the cutting of the rubber product. In addition, the height of the motor V21 and the disc 14 is adjusted by the electric push rod 4 to ensure that the cutter head 18 is in complete contact with the rubber product for cutting.

[0062] Reference Figures 1 to 5 As one embodiment of the present invention, specifically, the limiting assembly includes a motor II 8, a support base 9, a clamping plate 10, a threaded block 11, a guide groove 12, and a bidirectional screw 13. The top of the processing table 1 is provided with symmetrical guide grooves 12. A bidirectional screw 13 is installed inside the guide groove 12 on one side. A threaded block 11 is threadedly connected to the surface of the bidirectional screw 13. The top of the threaded block 11 is fixedly connected to the support base 9. The clamping plate 10 is fixedly connected to the inside of the support base 9. A sliding rod is provided inside the guide groove 12 on the other side, which is slidably connected to the support base 9.

[0063] By opening symmetrical guide grooves 12 on the top of the processing table 1, a bidirectional screw 13 is set in one guide groove 12 to connect the symmetrically arranged threaded blocks 11, support seats 9 and clamping plates 10. A sliding rod is set in the other guide groove 12 and slidably connected to the support seat 9. The bidirectional screw 13 is driven to rotate by a motor 8 outside the processing table 1. The bidirectional screw 13 drives the symmetrically arranged threaded blocks 11, support seats 9 and clamping plates 10 to move closer together, clamping and limiting the rubber product, and ensuring the stability of the rubber product during the cutting process.

[0064] Reference Figures 1 to 5 In one embodiment of the present invention, specifically, the processing table 1 is internally equipped with equidistant rollers 6, which are driven by a motor I2 on the surface of the processing table 1. A conveyor belt 5 is connected to the surface of the rollers 6. By setting equidistant rollers 6 on the top of the processing table 1 and connecting them to the conveyor belt 5, and driving the end rollers 6 with the motor I2, the motor I2 drives the conveyor belt 5 to move. Placing the rubber product on the surface of the conveyor belt 5 allows for the gradual progress of loading, cutting, and unloading, increasing the cutting and processing efficiency of the rubber product.

[0065] Reference Figure 1 , Figure 4 and Figure 5 In one embodiment of the present invention, a PLC control panel 7 is specifically mounted on the surface of the gantry frame 3. The PLC control panel 7 is connected to motor I2, electric push rod 4, motor II8, motor III17, motor IV19, and motor V21 respectively. The PLC control panel 7 controls and starts motor I2, electric push rod 4, motor II8, motor III17, motor IV19, and motor V21 to ensure the stability of the device during actual use.

[0066] A high-efficiency cutting device for cutting rubber products after molding, and a method for cutting rubber products, including the following steps: Step 1: First, adjust the position of the cutter head 18 according to the size of the rubber product to be circumferentially cut. Specifically, start the motor III 17 to drive the lead screw 15 to rotate. The lead screw 15 drives the slider 16, motor IV 19 and cutter head 18 to move together in the slide groove 20. The distance from the cutter head 18 to the center of the disc 14 is precisely adjusted. Step 2: Start motor I2 to drive roller 6 to rotate, which in turn drives conveyor belt 5 to move. Place the rubber product to be cut on the surface of conveyor belt 5 until the rubber product is transported to the position below gantry 3. Then start motor II8 to drive bidirectional screw 13 to rotate. The bidirectional screw drives the symmetrically arranged threaded blocks, support seats and clamps to come closer to clamp and limit the rubber product to ensure stability during the rubber product cutting process. Step 3: Start motor IV19 to drive the cutter head 18 to rotate. In addition, control the disc 14, motor IV19 and cutter head 18 to approach the rubber product through electric push rod 4. Finally, drive the disc 14, motor IV19 and cutter head 18 to perform circumferential cutting on the rubber product through motor V21.

[0067] Working principle: First, the distance between the cutter head 18 and the center of the disc 14 is precisely adjusted by the adjustment component. Then, the rubber product to be cut is transported to the position below the gantry 3 by the motor I2. The rubber product is then clamped and limited by the limiting component. Then, the motor IV19 is started to drive the cutter head 18 to rotate. In addition, the electric push rod 4 controls the disc 14, the motor IV19 and the cutter head 18 to approach the rubber product. The motor V21 drives the overall circumferential motion of the disc 14, the motor IV19 and the cutter head 18 to perform circumferential cutting on the rubber product. Specifically, motor III17 first drives screw 15 to rotate, which in turn drives slider 16, motor IV19, and cutter head 18 to move together within groove 20, precisely adjusting the distance between cutter head 18 and the center of disc 14. Then, motor I2 drives roller 6 to rotate, which in turn drives conveyor belt 5 to move, transferring the rubber product to be cut to a position below gantry 3. Next, motor II8 drives bidirectional screw 13 to rotate, which in turn drives symmetrically arranged threaded blocks, support seats, and clamping plates to move closer, clamping and limiting the rubber product. Then, motor IV19 is started to drive cutter head 18 to rotate. In addition, electric push rod 4 controls disc 14, motor IV19, and cutter head 18 to move closer to the rubber product. Finally, motor V21 drives the overall circular motion of disc 14, motor IV19, and cutter head 18 to perform circumferential cutting of the rubber product.

[0068] The present invention has the following advantages: 1. Stable and reliable structure, convenient installation and layout: The processing table has a solid structure and flexible support methods: the processing table consists of a platform and columns. The columns and platform are connected by welding or fasteners, or the platform is supported by a frame structure formed by connecting beams. The connection is firm and the load-bearing capacity is stable. It can withstand the vibration of cutting operations for a long time and ensure the reliable operation of the whole device. The gantry frame is flexible to install and has precise positioning: it can be integrated with the processing table (welded or fastened) for easy overall layout and installation in the workshop; or it can be set up separately across the platform and fixed to the ground. Through the convex and concave positioning structure (side bosses and grooves are compatible), it can achieve precise alignment with the platform, taking into account both installation flexibility and positioning accuracy, and adapting to different workshop layout needs. The components are compactly integrated: the gantry, adjustment components, and limit components are all integrated into the processing table or the main body of the gantry, with no redundant structures. In particular, the rollers are embedded in the flat plate and the drive structure is integrated into the disc slide, which further optimizes the space utilization, avoids component interference, and improves the overall neatness of the device.

[0069] 2. Highly efficient and precise cutting, adaptable to various processing needs. Outstanding cutting efficiency: The integrated conveyor belt and roller conveyor enable automatic feeding, cutting and unloading of rubber products in a continuous operation, eliminating the need for frequent manual handling and positioning, and greatly improving batch processing efficiency; The end rollers are embedded in the notched groove of the flat plate, eliminating the need for additional transition rollers, resulting in a compact structure and high transmission efficiency, further optimizing the conveying rhythm; The cutter head is flexible and versatile: the height of the cutter head and its distance from the center of the disc can be flexibly adjusted through the adjustment component, which can adapt to rubber products of different thicknesses and cut rubber products into circles / rings of different sizes without the need to change to special cutting equipment. It is suitable for processing various specifications of rubber products, reducing equipment investment costs; the adjustment method can be flexibly replaced (electric push rod, scissor lift, cylinder lift, etc., and the slider drive can use a lead screw or built-in electric push rod) to adapt to the needs of different workshop conditions; High cutting precision: The cutter head achieves circumferential cutting through a disc drive, and the motor drive ensures stable cutter head speed and smooth cutting. Combined with a precise position adjustment structure, it effectively avoids cutting deviation. At the same time, the limiting component firmly positions the plastic product, further ensuring that the plastic product does not shift during the cutting process and improving the cutting dimensional accuracy.

[0070] 3. Stable and secure positioning, suitable for complex working conditions. Precise and reliable limiting structure: The limiting component adopts a symmetrical clamping design, and the clamping plate is driven to move closer or further away synchronously through a bidirectional screw, so as to achieve rapid clamping and positioning of the adhesive. The inner side of the clamping plate is provided with a contour groove to fit the shape of the adhesive, making the clamping more secure. The clamping plate is also detachable and replaceable to adapt to different models of adhesive. The support base slides through a double guide groove, which ensures stable movement and avoids the adhesive from shifting due to force during clamping. Material positioning assistance optimization: The feeding and conveying area is equipped with a material adjustment structure (adjustable side plates or side rods with gradually varying spacing), which can automatically align the rubber products to the center of the conveyor belt and accurately align them with the limit components, ensuring the accuracy of subsequent clamping and positioning and reducing manual adjustment steps; the inner side of the gantry frame is equipped with a distance measuring sensor or vision module, which can automatically detect the position of the rubber products and control the action of the clamping structure, improving the degree of positioning automation; Suitable for low-temperature working conditions: The inner side of the gantry is equipped with a heating structure (radiation heating or baking heating), which can increase the temperature of the rubber when the air temperature is low, avoid cutting jams and uneven cuts caused by the rubber becoming brittle and hardening at low temperatures, and ensure stable cutting in all weather conditions.

[0071] 4. High degree of automation, convenient operation and easy maintenance Integrated automated control: The PLC control panel enables centralized control of all motors and electric actuators, automating the entire process of rubber product loading, positioning, cutting, and unloading without manual intervention. This simplifies operation, reduces human error, and improves processing consistency. Easy-to-maintain structure: The connection of each component is simple (welding or fastener connection), which is convenient for disassembly, maintenance and replacement; the slider, lead screw and other adjustment structures are integrated into the disc slide groove, which reduces dust and glue residue adhesion, reduces wear and extends service life; the adjustment side plate can be replaced with the adjustment side rod, which reduces the risk of glue jamming and reduces maintenance costs. Highly adaptable to different workshops: The overall structure of the device can be flexibly arranged (the gantry and processing table can be integrated or set up separately), with a reasonable floor area, making it easy to integrate into existing production lines without requiring major modifications to the workshop layout, and adaptable to the installation and use needs of various workshops.

[0072] 5. Integrated settings, stable and reliable operation. The design of each structure of the device is based on the actual needs of rubber cutting, taking into account efficiency, stability and versatility: it not only solves the problems of inconvenient blade adjustment and poor versatility of traditional cutting devices, but also overcomes the pain points of unstable rubber positioning and difficulty in low-temperature cutting; at the same time, the automated process design reduces the intensity of manual labor, significantly improves batch processing efficiency, and can be perfectly adapted to continuous and large-scale cutting operations after rubber molding, with outstanding practicality and economy.
