Description

Technical Field

[0001] This utility model belongs to the field of rubber slicing machines, and specifically relates to a rubber slicing machine and a noise reduction structure. Background Technology

[0002] A rubber slicer is a device specifically designed to precisely cut rubber blocks or strips into thin slices. It is widely used in the rubber products industry. For traditional rubber slicers lacking three-axis linkage, accuracy and noise issues are particularly prominent. Insufficient accuracy manifests primarily as uneven slice thickness and rough edges, mainly due to poor mechanical rigidity, gaps in the transmission system (such as gears or belts), and cumulative errors caused by reliance on manual feeding. Simultaneously, radial runout and wear of the cutting tool further exacerbate thickness fluctuations. High noise stems from multiple sources: the high-speed rotating cutting tool rubbing against the rubber generates harsh cutting noise, and high-frequency fluctuations in air pressure produce a "whistling" sound, causing noise to spread widely in the workshop environment, ultimately affecting production efficiency and the working environment. Therefore, we aim to design a rubber slicer and a noise reduction structure to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rubber slicer and a noise reduction structure to solve the problems mentioned in the background technology.

The three-axis coordination mechanism includes a gantry frame, an X-axis adjustment component is provided at the lower end of the gantry frame, a Y-axis adjustment component is provided on the inner side of the gantry frame, and a Z-axis movement component is provided on the Y-axis adjustment component. The three-axis coordination mechanism also includes a mounting plate on which an adjustment motor for adjusting the cutter angle is fixedly mounted. By setting up the three-axis coordination mechanism, a servo motor drives the screw to control the XYZ three-axis displacement, which has significant advantages of high precision and good flexibility. It can accurately control the path, thickness and shape of the slice through the CNC system, and is particularly suitable for products with complex contours and high precision requirements. At the same time, it runs more smoothly and with lower noise, improving the consistency of slice quality.

The mounting cylinder has a through groove, and a ball bearing is movably fitted inside the through groove. The through groove has an arc-shaped structure that is narrower at one end near the center of the mounting cylinder and wider at the other end away from the center, which is used to prevent the ball bearing from falling out of the mounting cylinder.

Detailed Implementation

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As the first embodiment of this utility model: A rubber slicer and noise reduction structure include: a base 1, a cutting pad made of polyurethane that is detachably installed on the upper surface of the base 1 to ensure thorough cutting, a three-axis coordination mechanism 2 for adjusting the displacement of the cutter 4 on the base 1, and a connecting mechanism 3 for mounting the cutter 4 on the three-axis coordination mechanism 2. The three-axis coordination mechanism 2 includes a gantry 21, an X-axis adjustment component 22 is provided at the lower end of the gantry 21, a Y-axis adjustment component 23 is provided on the inner side of the gantry 21, and a Z-axis movement component 24 is provided on the Y-axis adjustment component 23. The three-axis coordination mechanism 2 also includes a mounting plate 25, on which an adjustment motor 26 for adjusting the angle of the cutter 4 is fixedly mounted. By setting up the three-axis coordination mechanism 2, the screw driven by the servo motor is used to control the XYZ three-axis displacement, which has the significant advantages of high precision and good flexibility. It can accurately control the path, thickness and shape of the slice through the CNC system, and is particularly suitable for products with complex contours and high precision requirements. At the same time, it runs more smoothly and with lower noise, improving the consistency of slice quality.

[0024] The X-axis adjustment assembly 22 includes a slide block 221, which is fixedly connected to the bottom surface of the gantry frame 21. The slide block 221 is slidably sleeved on the outside of the slide rod 11. A connecting block 222 is fixedly connected to the bottom surface of the gantry frame 21. A screw 224 is also sleeved inside the base 1 through a bearing. The connecting block 222 is screwed onto the outside of the screw 224 through a thread.

[0025] The Y-axis adjustment assembly 23 includes a slide bar 231 and a support frame 234. The slide bar 231 is fixedly connected to the inner side of the gantry frame 21. The gantry frame 21 is fitted with a screw rod 2 through a bearing. A slider 235 is fixedly connected to the right side surface of the support frame 234. The slider 235 is slidably fitted to the outer side of the slide bar 231. A connecting block 236 is also fixedly connected to the right side surface of the support frame 234. The connecting block 236 is screwed onto the outer side of the screw rod 233 through a thread.

[0026] Z-axis moving assembly 24 includes a vertical screw 242, which is sleeved inside the support frame 234 via a bearing. A mounting block 243 is threaded onto the outer side of the vertical screw 242. A guide rod 244 is also fixedly connected to the inner side of the support frame 234. The guide rod 244 is slidably connected to the mounting block 243. A mounting plate 25 is fixedly connected to the left side surface of the mounting block 243.

[0027] Servo motor 1 223, servo motor 232, and servo motor 3 241 are fixedly mounted on the right side surface of base 1, the rear side surface of gantry 21, and the upper side surface of support frame 234 respectively via mounting brackets. The output shafts of servo motor 1, servo motor 232, and servo motor 3 241 are fixedly connected to screw 1 224, screw 233, and vertical screw 242 respectively via couplings.

[0028] By setting up a three-axis coordination mechanism 2 consisting of X-axis, Y-axis, and Z-axis adjustment components, the high-speed rotation of the traditional cutting blade is avoided. This avoids the problem of the cutting blade edge disturbing the surrounding air and generating a series of eddies. These eddies are constantly generated and detached, causing high-frequency fluctuations in air pressure and producing a "whistling" sound. In conjunction with the adjustment motor 26 installed on the Y-axis component, the cutter 4 is driven to adjust its angle. During operation, each servo motor drives the screw 1 224, screw 233, and vertical screw 242 to rotate, which in turn drives the connecting block 1 222, connecting block 236 2, and mounting block 243 screwed onto them to move precisely along the direction of the slide bar, achieving high-precision positioning and trajectory control of the cutter 4 in three-dimensional space. At the same time, through the coordinated control of the movement of each axis and the posture of the cutter 4 by the CNC system, the path, thickness, and complex shape of the slice can be precisely adjusted, ultimately achieving high-quality, high-consistency, and low-noise slicing operations.

[0029] Please see Figure 1 , Figure 4 , Figure 5 as well as Figure 6 As a second embodiment of this utility model: The connecting mechanism 3 includes a mounting cylinder 31, which is fixedly connected to the output shaft of the adjusting motor 26. A through groove is provided on the mounting cylinder 31, and a ball bearing 32 is movably fitted inside the through groove. The through groove has an arc-shaped structure that is narrower at one end near the center of the mounting cylinder 31 and wider at the other end away from the center, which is used to prevent the ball bearing 32 from falling out of the mounting cylinder 31. By setting the connecting mechanism 3, the cutter 4 can be quickly replaced, which significantly shortens the downtime for changing the cutter and ensures the continuity and flexibility of the production line.

[0030] A fixing ring 33 is fixedly sleeved on the outside of the mounting cylinder 31, and a limiting ring 34 is also slidably sleeved on the outside of the mounting cylinder 31. The limiting ring 34 and the fixing ring 33 are elastically connected by a spring 35.

[0031] The handle of the cutter 4 has a groove 41, and the ball bearing 32 is movably fitted into the inside of the groove 41.

[0032] Based on the above embodiments, when it is necessary to replace the cutter 4, first push the limiting collar 34 upward. During the movement of the limiting collar 34, the spring 35 is compressed and deformed. When the limiting collar 34 moves to the point where its inner annular groove is aligned with the ball 32, the handle of the cutter 4 is moved downward. At the same time, the handle squeezes the ball 32 and causes it to move into the inner annular groove, thereby separating it from the groove 41 of the handle to complete the disassembly and replacement of the cutter 4.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
