Description
Technical Field
[0001] This application relates to the field of rubber product technology, specifically to an automated rubber trimming machine. Background Technology
[0002] During the vulcanization process of rubber products, excess rubber edges are easily generated at the parting surface, gate, and other locations. Trimming is a key process to ensure the appearance quality and assembly accuracy of rubber products. As the rubber industry develops towards automation and precision, the drawbacks of traditional manual trimming, such as low efficiency and poor quality stability, have become increasingly prominent. Automated rubber trimming machines have emerged and become the mainstream equipment in the industry.
[0003] While existing automated rubber trimming equipment has achieved basic mechanical automation, the position and angle of the trimming blades on the equipment are mostly fixed. When the size and shape of the rubber product to be trimmed changes, the equipment cannot trim the changed rubber product. The rubber trimming equipment has significant limitations in trimming rubber products, reducing trimming efficiency. Furthermore, most existing automated rubber trimming equipment cannot clean up the waste material generated during the trimming process, resulting in waste material accumulating on the worktable. Excessive waste material accumulation may affect the trimming effect.
[0004] Therefore, it is necessary to provide an automated rubber trimming machine to solve the above problems.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

A telescopic adjustment rod is telescopically connected inside the limiting cavities. An adjustment gear disk is provided at one end of the limiting cavities. The middle part of the adjustment gear disk is rotatably connected to the middle part of the tabletop via a shaft.

[0015] The beneficial effects of this application are: it facilitates multi-directional and multi-angle adjustment of the trimming knife, which is conducive to improving the effect of rubber trimming; it facilitates automatic cleaning of the rubber residue generated during the trimming process, which helps to prevent the accumulation of residue from affecting the trimming effect.
[0016] Specifically: This application utilizes a first motor, turntable, first guide rail plate, second guide rail plate, fourth motor, first lead screw, first slider, fifth motor, second lead screw, fixed support frame, trimming knife, sixth motor, worm gear, turbine roller, and adjusting rotating plate. For a circular workpiece, the first motor drives the turntable to rotate, aligning the trimming knife with the starting point of the workpiece's edge. The rotating turntable, driven by the first motor, causes the trimming knife mounted on the translation mechanism to rotate along the outer edge of the circular workpiece, trimming it. For a square rubber part, the fourth motor drives one of the synchronous pulleys to rotate, which in turn drives the other synchronous pulley to rotate synchronously via a synchronous belt. This causes the first lead screws within the two first guide rail plates to rotate in the same direction and at the same speed. The first slider is threadedly engaged with the first lead screw and is fixedly connected to the second guide rail plate. Therefore, when the first lead screw rotates, it drives the second guide plate to slide along the length direction (X direction) of the first guide plate to the extension line of the workpiece to be trimmed. The fifth motor drives the second lead screw inside the second guide plate to rotate, and the second slider threadedly connected to the second lead screw drives the fixed support frame to slide along the length direction (Y direction) of the second guide plate, so that the trimming blade edge contacts the starting trimming point of the workpiece. The sixth motor drives the worm gear to rotate, and the worm gear meshes with the turbine roller (integrated turbine in the middle) fixed on the fixed support frame. Since the turbine roller is fixed, the worm gear drives the adjusting plate to rotate around the axis of the turbine roller. The adjusting plate rotates 45 degrees to keep the trimming blade edge in contact with the inclined edge of the workpiece. The first motor drives the turntable to rotate 90 degrees to perform right-angle trimming, which facilitates multi-directional and multi-angle adjustment of the trimming blade and helps to improve the trimming effect of rubber.
[0017] This application, through the setting of a second motor, a cleaning fan, and a protective cylinder, enables the central control system to start the second motor when the trimming knife trims the workpiece. The second motor drives the cleaning fan to rotate, and the rotation of the cleaning fan generates airflow that flows outward through the air holes on the protective cylinder. When the airflow comes into contact with the debris generated during trimming, it blows the rubber debris generated during trimming outward from the table, causing the airflow to carry the debris off the table. This facilitates the automatic cleaning of the rubber residue generated during the trimming process and helps prevent the accumulation of residue from affecting the trimming effect.

[0031] like Figure 1-7 As shown, this application provides an automated rubber trimming machine, including a worktable 1. A hydraulic telescopic rod 3 is fixedly installed on each of the three surfaces of the worktable 1. A hanging plate 4 is fixed to the top of the hydraulic telescopic rod 3.

A fixed support frame 10 is fixed to one end of the second slider 32. A second lead screw 35 passes through the middle of the second slider 32.

The two ends of the first lead screw 34 are rotatably connected to the two ends inside the first guide plate 9. A synchronous pulley 15 is fixed to one end of the first lead screw 34 and rotatably connected to the first guide plate 9. The synchronous pulleys 15 on the two first guide plates 9 are connected by a synchronous belt. 16. Transmission connection: One end of one of the two synchronous pulleys 15 is fixed with a fourth motor 30. Dust covers are provided on both the first lead screw 34 and the second lead screw 35. The second guide plate 14 is slidably connected to the two first guide plates 9 through the first slider 33, forming a translation system. One end of the fixed support frame 10 is fixed with a turbine roller 36. An adjusting plate 11 is rotatably connected inside one end of the fixed support frame 10. A protective sealing plate 39 is snapped onto the adjusting plate 11. One end of the adjusting plate 11 is provided with a worm gear 38 that meshes with the turbine roller 36. Both ends of the worm gear 38 are equipped with a positioning block plate that is fixedly connected to the adjusting plate 11. The worm gear 38 rotates with the positioning block plate. The system is connected by a worm gear 38, with a sixth motor 37 fixed at one end and mounted on a positioning block. A fixing plate 40 is bolted to one end of the adjusting plate 11, and a trimming knife 23 is fixed between the fixing plate 40 and the adjusting plate 11. A limiting ring 13 is fixedly connected to the turntable 12 and the hanging plate 4. A guide ring groove is provided at the connection position between the limiting ring 13 and the hanging plate 4. A turbine is fixed in the middle of the turbine roller 36, and a guide ring is fixed at the connection position between the turbine roller 36 and the adjusting plate 11. A guide groove is provided at the connection position between the adjusting plate 11 and the guide ring, forming an angle adjustment system.
[0032] In this embodiment, after the operator places the rubber workpiece on the workbench 1, they input the workpiece thickness parameter (e.g., 20mm). The central control system instructs the three hydraulic telescopic rods 3 to extend and retract synchronously (the extension and retraction are controlled to be consistent by a flow valve), driving the hanging plate 4 to rise and fall to the initial distance between the trimming knife 23 and the workpiece surface (usually 5-10mm). At this time, the triangular distribution of the three hydraulic telescopic rods 3 ensures that the horizontal error of the hanging plate 4 is ≤0.5mm, providing a reference for subsequent planar adjustment. If it is a circular workpiece, the center of the workpiece is identified by a vision positioning system (which can be externally connected). The central control system first drives the first motor 8 to... The rotating turntable 12 rotates, aligning the trimming blade 23 with the starting point of the workpiece edge. The position is then finely adjusted via a translation system to ensure the lateral alignment accuracy between the trimming blade and the edge to be trimmed is ≤0.1mm. For square rubber parts, the fourth motor 30 drives one of the synchronous pulleys 15 to rotate, which in turn drives the other synchronous pulley 15 to rotate synchronously via the synchronous belt 16. This causes the first lead screws 34 within the two first guide rail plates 9 to rotate in the same direction and at the same speed. The first slider 33 is threadedly engaged with the first lead screw 34 and is fixedly connected to the second guide rail plate 14. Therefore, when the first lead screw 34 rotates, it drives the second guide rail plate 14 along the length direction (X) of the first guide rail plate 9. The fifth motor 31 drives the second lead screw 35 inside the second guide plate 14 to rotate, and the second slider 32, which is threaded to the second lead screw 35, drives the fixed support frame 10 to slide along the length direction (Y direction) of the second guide plate 14, so that the cutting edge of the trimming knife 23 contacts the starting trimming point of the workpiece. The sixth motor 37 drives the worm gear 38 to rotate, and the worm gear 38 meshes with the turbine roller 36 (with a turbine integrated in the middle) fixed on the fixed support frame 10. Since the turbine roller 36 is fixed, the worm gear 38 drives the adjusting plate 11 to rotate around the axis of the turbine roller 36. The adjusting plate 11 rotates 45 degrees, so that... The trimming blade edge remains in contact with the workpiece's bevel. The self-locking characteristic of the worm gear allows the adjusting plate 11 to lock in the adjusted angular position. The first motor 8 drives the turntable 12 to rotate 90 degrees, while the two-dimensional translation system moves synchronously in the opposite direction, moving the trimming blade 23 from one corner of the workpiece to the starting point of the next bevel. Throughout the switching process, the distance between the trimming blade 23 and the workpiece remains unchanged (achieved by locking the height using the hydraulic telescopic rod 3). When the turntable 12 rotates, the limiting ring 13 slides in the guide ring groove, forming a rotational translational guiding coordination with the rigid connection of the first guide plate 9 and the second guide plate 14, thus avoiding structural swaying caused by centrifugal force.
[0033] It should be noted that the first motor 8 is a servo motor, which precisely controls the rotation angle through pulse signals. It can achieve 360-degree continuous rotation or step-by-step positioning at a specific angle (such as pausing once every 90 degrees when trimming the four corners of a square rubber part), meeting the trimming trajectory requirements of workpieces of different shapes. The symmetrical design of the double guide rail and double lead screw can avoid tilting when the second guide rail plate 14 is translated, ensuring that the X-axis movement straightness error is ≤0.05mm / m. The dust cover outside the first lead screw 34 and the second lead screw 35 can prevent rubber debris from entering the threaded transmission pair, avoiding jamming or wear and extending the transmission life. The three hydraulic telescopic rods 3 are distributed in a triangle between the worktable 1 and the hanging plate 4. The guide rings at both ends of the turbine roller 36 are embedded in the guide groove of the adjusting plate 11, ensuring the stability of the axis rotation of the adjusting plate 11 during the rotation process.
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a tabletop 2 is fixed to one end of the workbench 1. Multiple guide grooves 25 are equidistantly spaced along the circumference of the tabletop 2. Multiple limiting cavities 21 are equidistantly fixed along the circumference of the end of the tabletop 2 facing inwards from the workbench 1. A telescopic adjusting rod 22 is telescopically connected within the limiting cavities 21. An adjusting gear disk 19 is provided at one end of the limiting cavities 21. The middle of the adjusting gear disk 19 is rotatably connected to the middle of the tabletop 2 via a shaft. Multiple guide arc grooves 20 are equidistantly spaced along the circumference of the adjusting gear disk 19. A guide column block 29, which is slidably connected to the guide arc groove 20, is fixed to the middle of one end of the telescopic adjusting rod 22. A screw thread is used to connect the telescopic adjusting rod 22 to the guide column block 29. A clamping plate 5 is fixedly installed on the clamping plate 5, and a pressure sensing rod 6 is rotatably connected to the clamping plate 5. A drive gear 26 is meshed with the middle of one end of the adjusting gear disk 19. A third motor 27 is fixed to one end of the drive gear 26. A fixed frame plate 28, which is fixedly connected to the table 2, is installed outside the third motor 27. A cleaning fan 24 is rotatably connected to the middle of the other end of the table 2. One end of the cleaning fan 24 is connected through a shaft that is rotatably connected to the middle of one end of the table 2. A second motor 18 is fixed to one end of the shaft. A bracket frame plate 17, which is fixedly connected to the table 2 by bolts, is provided at one end of the second motor 18. A protective cylinder 7, which is fixedly connected to the table 2, is provided outside the cleaning fan 24.
[0035] In this embodiment, the rubber workpiece is placed on the outside of the pressure sensing rod 6 installed on the clamping plate 5 at the top of the table 2. The third motor 27 drives the drive gear 26 to rotate, which in turn drives the adjusting gear disk 19 to rotate around the central axis of the table 2 through gear meshing. The guide arc groove 20 on the adjusting gear disk 19 rotates synchronously with it. The guide column block 29 slidably connected in the guide arc groove 20 is constrained by the arc groove contour, converting the rotational motion into the radial linear motion of the telescopic adjusting rod 22 along the limiting cavity plate 21. When the adjusting gear disk 19 rotates clockwise, the guide arc groove 20 pushes the guide column block 29 to move away from the center, thereby driving the telescopic adjusting rod 22 to slide outward along the limiting cavity plate 21, and driving the clamping plate 5 fixed on the telescopic adjusting rod 22 and the clamping plate 5 with one end set Some pressure sensing rods 6 move towards the inner wall of the rubber part. When the pressure sensing rods 6 on the clamping plate 5 come into contact with the workpiece, they detect the clamping pressure in real time (range 0-50N) and transmit the signal to the central control system. When the pressure reaches the preset threshold (e.g., 10N for thin-walled parts and 30N for thick-walled parts), the system commands the third motor 27 to stop to avoid overpressure causing workpiece deformation. When the trimming knife 23 trims the workpiece, the central control system commands the second motor 18 to start. The second motor 18 drives the cleaning fan 24 to rotate (speed 1000-2000r / min). The rotation of the cleaning fan 24 forms an airflow that blows the rubber debris generated during trimming outwards from the table 2, causing the airflow to carry the debris off the table 2, thus completing the debris cleaning.
[0036] Working principle: The rubber workpiece is placed on the outside of the pressure sensing rod 6 installed on the clamping plate 5 at the top of the table 2. The third motor 27 drives the drive gear 26 to rotate, which in turn drives the adjusting gear disk 19 to rotate around the central axis of the table 2. The guide arc groove 20 on the adjusting gear disk 19 rotates synchronously with it. The guide column block 29, which is slidably connected in the guide arc groove 20, is constrained by the arc groove contour, converting the rotational motion into the radial linear motion of the telescopic adjusting rod 22 along the limiting cavity plate 21. When the adjusting gear disk 19 rotates clockwise, the guide arc groove 20 pushes the guide column block 29 to move away from the center, thereby driving the telescopic adjusting rod 22 to slide outward along the limiting cavity plate 21. This causes the clamping plate 5 and the pressure sensing rod 6 at one end of the clamping plate 5, which are fixed on the telescopic adjusting rod 22, to move towards the inner wall of the rubber workpiece. When the pressure sensing rod 6 on the clamping plate 5 contacts the workpiece, the clamping pressure is detected in real time (range 0-5). The system transmits the signal to the central control system. When the pressure reaches the preset threshold (e.g., 10N for thin-walled parts and 30N for thick-walled parts), the system instructs the third motor 27 to stop to prevent overpressure from causing workpiece deformation. The central control system instructs the three hydraulic telescopic rods 3 to extend and retract synchronously (the extension and retraction are controlled by the flow valve to be consistent), driving the hanging plate 4 to rise and fall to the initial distance between the trimming knife 23 and the workpiece surface (usually 5-10mm). At this time, the triangular distribution of the three hydraulic telescopic rods 3 ensures that the horizontal error of the hanging plate 4 is ≤0.5mm, providing a reference for subsequent plane adjustment. If it is a circular workpiece, the center of the workpiece is identified by the visual positioning system (which can be externally connected). The central control system first drives the first motor 8 to rotate the turntable 12 so that the trimming knife 23 is aligned with the starting point of the workpiece edge. Then, the position is finely adjusted by the translation system to ensure that the lateral alignment accuracy of the trimming knife edge and the edge to be trimmed is ≤0.1mm. The first motor 8 drives the turntable 12 to rotate. The rotating turntable drives the trimming knife 23 mounted on the translation mechanism to rotate along the outer edge of the circular workpiece to trim the circular workpiece. If it is a square rubber part, the fourth motor 30 drives one of the synchronous pulleys 15 to rotate, and drives the other synchronous pulley 15 to rotate synchronously through the synchronous belt 16. This causes the first lead screws 34 in the two first guide rail plates 9 to rotate in the same direction and at the same speed. The first slider 33 is threaded with the first lead screw 34 and is fixedly connected to the second guide rail plate 14. Therefore, when the first lead screw 34 rotates, it drives the second guide rail plate 14 to slide along the length direction (X direction) of the first guide rail plate 9 to the extension line of the workpiece to be trimmed. The fifth motor 31 drives the second lead screw 35 in the second guide rail plate 14 to rotate. The second slider 32, which is threadedly connected to the second lead screw 35, drives the fixed support frame 10 to slide along the length direction (Y direction) of the second guide rail plate 14, so that the cutting edge of the trimming knife 23 contacts the starting trimming point of the workpiece. The sixth motor 37 drives the worm gear 38 to rotate. The worm gear 38 meshes with the turbine roller 36 (with an integrated turbine in the middle) fixed on the fixed support frame 10. Since the turbine roller 36 is stationary, the worm gear 38 drives the adjusting plate 11 to rotate around the axis of the turbine roller 36. The adjusting plate 11 rotates 45 degrees, keeping the trimming blade edge in contact with the bevel of the workpiece. The self-locking characteristic of the worm gear allows the adjusting plate 11 to lock in the adjusted angular position. The first motor 8 drives the turntable 12 to rotate 90 degrees, while the translation system moves synchronously in the opposite direction, moving the trimming blade 23 from one corner of the workpiece to the starting point of the next bevel. When the trimming blade 23 trims the workpiece, the central control system simultaneously instructs the second motor 18 to start. The second motor 18 drives the cleaning fan 24 to rotate (speed 1000-2000 r / min). The rotating cleaning fan 24 generates airflow, blowing the rubber debris generated during trimming outwards from the table 2, causing the airflow to carry the debris off the table 2, completing the debris cleaning.
