Description

Technical Field

[0001] This utility model relates to the technical field of tire manufacturing, and in particular to a rubber calendering bubble-scraping device. Background Technology

[0002] Rubber calenders are one of the basic pieces of equipment in the processing of rubber and plastic products. Among rubber and plastic machinery, calenders are classified as heavy-duty, high-precision machines. The basic structure of a rubber calender is very similar to that of a plastic calender, and their working principles are essentially the same. During tire production, high rubber compound temperatures, mixing issues, and rubber supply problems during calendering lead to the generation of gas between the calender rollers and the rubber sheet, forming numerous air bubbles. These bubbles have low permeability within the rubber sheet and are difficult to escape, resulting in uneven rubber sheet thickness and affecting tire quality. The prior art publication number CN210940135U discloses an automatic bubble-breaking device for a calender, which includes a base, a frame mounted on the base, and two spaced-apart discharge rollers rotatably mounted on the frame. The device is characterized by: a lead screw rotatably mounted on the frame behind the gap between the discharge rollers, the lead screw being parallel to the axis of the discharge rollers, and a nut screwed onto the lead screw; a motor for driving the lead screw to rotate mounted on the frame; a light shaft passing through the nut fixed on the frame, the light shaft being parallel to the axis of the lead screw and slidingly engaged with the nut; a cylinder mounted on the nut, the top of the cylinder facing the gap between the two discharge rollers; a knife holder mounted on the top of the cylinder, with knives mounted behind the gap for breaking bubbles. However, traditional bubble cutters use a continuous, round blade with a sharp edge to cut bubbles; the sharp blade cuts the film deeply, which can easily damage the surface of the four rollers; at the same time, the continuous blade creates a continuous cut when cutting the film, resulting in a long cut, and the film can easily separate from the cut line, which can lead to insufficient glue in the product. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a rubber calendering bubble-cutting device that can draw serpentine curves on thin film, continuously and evenly break air bubbles, and ensure that the film remains connected after the air bubbles are broken, making it convenient to use and improving its practicality.

[0004] This utility model discloses a rubber calendering bubble-splitting device, comprising a calender frame, a crossbeam, a position adjustment component, a connecting component, a splitting component, and a guiding component. The crossbeam is installed between the calender frames, located on one side of the calender rollers. The position adjustment component is installed inside the crossbeam, and the guiding component is installed between the position adjustment component and the crossbeam. The splitting component is installed on the top of the position adjustment component via the connecting component. The position adjustment component drives the splitting component to move back and forth, splitting a serpentine curve on the thin rubber sheet, continuously and evenly splitting bubbles. The movement allows the guiding component to provide support and guidance, ensuring stability during movement. The connecting component allows the splitting component to be easily removed for replacement and maintenance, making it convenient to use and improving practicality.

[0005] Preferably, the position adjustment component includes a fixed rod, multiple sliding blocks, a fixed plate, a drive motor, a turntable, a connecting seat, a rocker arm, and a rotating shaft. An adjustment groove is formed inside the crossbeam, and the fixed rod is located within the adjustment groove. Multiple sliding blocks are mounted on the outer wall of the fixed rod, and these blocks are slidably installed within the adjustment groove. The fixed plate is mounted on the outer wall of the left end of the calender frame. The drive motor is mounted on the top of the fixed plate, and a turntable is mounted on the output end of the drive motor. A connecting seat is mounted on the left end of the fixed rod. One end of the rocker arm is rotatably connected to the connecting seat, and the other end of the rocker arm is rotatably mounted on a rotating shaft, which is eccentrically mounted on the outer wall of the turntable. Starting the drive motor rotates the turntable, and the turntable moves the rocker arm via the rotating shaft. This causes the rocker arm to pull the fixed rod and sliding blocks within the adjustment groove via the connecting seat, enabling the drawing of a serpentine curve on the thin film and the continuous and uniform breaking of air bubbles.

[0006] Preferably, the assembly also includes multiple slide rods, a fixed plate, a sliding plate, and multiple springs. The slide rods are axially distributed about the fixed rod and installed on the outer wall of the right-side calender frame. A fixed plate is installed at the outer end of each slide rod, and a sliding plate is installed at the right end of the fixed rod. The sliding plate is slidably installed on the outer wall of the slide rod. Multiple springs are respectively fitted onto the outer walls of the slide rods. One end of each spring is connected to the outer wall of the calender frame, and the other end is connected to the sliding plate. When the fixed rod moves to the left, it causes the sliding plate to slide on the slide rod and compress the spring. When the fixed rod moves to the right, the spring force pushes the sliding plate to slide on the slide rod, thereby enabling the fixed rod to move back and forth.

[0007] Preferably, the slicing component includes multiple connecting plates, multiple fixed arms, and multiple bubble cutters. The connecting plates are located above the sliding block, and fixed arms are installed on the top of the connecting plates. Bubble cutters are installed on the top of the fixed arms via a rotating shaft. Multiple cutting teeth are axially arranged on the outer wall of the bubble cutter, and the outermost radial surface of the cutting teeth is provided with a blade grinding surface. During processing, a fixed arm that meets the processing requirements is selected so that the bubble cutter contacts the rubber sheet and slicing the bubble to complete the rubber calendering bubble slicing process. The blade grinding surface avoids the situation where the cut is too deep when the blade with a sharp edge slices the rubber sheet, thus protecting the roller surface. At the same time, the distance between the cutting teeth allows the rubber sheet to remain connected after slicing the bubble, avoiding the formation of continuous cuts on the rubber sheet and causing the rubber sheet to separate from the cutting line, thereby ensuring that the product does not lack rubber.

[0008] Preferably, the connecting component includes multiple fixed seats, multiple connecting blocks, and multiple pins. The fixed seats are installed on the top of the sliding block, and a connecting slot is provided on the top of the fixed seats. A connecting block that matches the connecting slot is installed on the bottom of the connecting plate. Connecting holes are provided on the fixed seats and connecting blocks. The pins are inserted into the connecting holes, and a wing nut is provided on the other end of the pins. By unscrewing the wing nut and pulling the pin out of the connecting hole, the connecting block can be moved out of the connecting slot, which facilitates the replacement and maintenance of the bubble cutter and improves convenience.

[0009] Preferably, the guiding component includes two guide rods, two extension plates, a guide strut, and multiple guide sliders. Guide grooves are provided on the left and right sides inside the adjustment slot of the crossbeam. The guide rods are installed in the guide grooves. The front and rear ends of the sliding block are slidably mounted on the outer wall of the guide rod. Extension plates are installed at the left and right ends of the bottom of the crossbeam, and a guide strut is installed between the two extension plates. A guide slider is installed at the bottom of the sliding block, and the guide slider is slidably mounted on the outer wall of the guide strut. When the sliding block moves, it slides on the guide rod, and simultaneously, the sliding block drives the guide slider to slide on the guide strut, guiding and limiting it, improving structural strength, and ensuring stability during operation.

[0010] Preferably, it also includes two tie rods, which are installed at the front and rear ends of the top of the fixed plate. The other end of the tie rod is connected to the outer wall of the calender frame, and the output end of the drive motor is rotatably installed on the rear tie rod. The tie rods increase the connection strength between the fixed plate and the calender frame, ensuring stability during use.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the position adjustment component drives the slicing component to move back and forth, drawing a serpentine curve on the thin film to continuously and evenly slicing the air bubbles. The movement enables the guide component to provide support and guidance, ensuring stability during movement. The connecting component makes it easy to remove the slicing component for easy replacement and maintenance, making it convenient to use and improving its practicality. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] like Figures 1 to 5As shown, the crossbeam 2 is installed between the frames 1 of the calender, located on one side of the calender's pressure rollers. An adjustment groove is provided inside the crossbeam 2, and a fixed rod 3 is located within the adjustment groove. Multiple sliding blocks 4 are installed on the outer wall of the fixed rod 3, and the sliding blocks 4 are slidably installed within the adjustment groove. A fixed plate 5 is installed on the outer wall of the left end of the calender frame 1. A drive motor 6 is installed on the top of the fixed plate 5, and a turntable 7 is installed at the output end of the drive motor 6. A connecting seat 8 is installed at the left end of the fixed rod 3. One end of a rocker arm 9 is rotatably connected to the connecting seat 8, and the other end of the rocker arm 9 is rotatably mounted with a rotating shaft 10. The rotating shaft 10 is eccentrically mounted on the outer wall of the turntable 7. Multiple sliding rods 22 are axially distributed about the fixed rod 3 and mounted on the outer wall of the right-side calender frame 1. A fixed plate 23 is mounted on the outer end of the sliding rod 22, and a sliding plate 24 is mounted on the right end of the fixed rod 3. The sliding plate 24 is slidably mounted on the outer wall of the sliding rod 22. Multiple springs 25 are respectively fitted on the outer wall of the multiple sliding rods 22. One end of the spring 25 is connected to the outer wall of the calender frame 1, and the other end of the spring 25 is connected to the sliding plate 24. A connecting plate 19 is located above the sliding block 4, and a fixed arm is mounted on the top of the connecting plate 19. 20. A bubble cutter 21 is mounted on the top of the fixed arm 20 via a pivot. Multiple teeth are axially arranged on the outer wall of the bubble cutter 21, with a grinding surface on the outermost radial side of each tooth. A fixed base 16 is mounted on the top of the sliding block 4. A connecting slot is provided on the top of the fixed base 16. A connecting block 17 matching the connecting slot is installed on the bottom of the connecting plate 19. Connecting holes are provided on the fixed base 16 and the connecting block 17. A pin 18 is inserted into the connecting hole, and a wing nut is provided at the other end of the pin 18. Adjustment grooves are provided on the left and right sides inside the crossbeam 2. There is a guide groove, the guide rod 12 is installed in the guide groove, the front and rear ends of the sliding block 4 are slidably installed on the outer wall of the guide rod 12, the bottom left and right ends of the crossbeam 2 are equipped with extension plates 13, the two extension plates 13 are installed between the two extension plates 13, the bottom of the sliding block 4 is equipped with a guide slider 15, the guide slider 15 is slidably installed on the outer wall of the guide support rod 14, the two pull rods 11 are installed at the front and rear ends of the top of the fixed plate 5, the other end of the pull rod 11 is connected to the outer wall of the calender frame 1, and the output end of the drive motor 6 is rotatably installed on the rear pull rod 11;

[0020] The drive motor 6 is started, which drives the turntable 7 to rotate. The turntable 7 drives the rocker arm 9 to move via the rotating shaft 10. This causes the rocker arm 9 to pull the fixed rod 3 and the sliding block 4 to move within the adjustment groove via the connecting seat 8. This enables the function of drawing a serpentine curve on the thin film and continuously and evenly breaking the air bubbles. When the fixed rod 3 moves to the left, it drives the sliding disk 24 to slide on the sliding rod 22 and compress the spring 25. When the fixed rod 3 moves to the right, the elastic force of the spring 25 pushes the sliding disk 24 to slide on the sliding rod 22, so that the fixed rod 3 can move back and forth. During processing, the fixed arm 20 that meets the processing requirements is selected so that the bubble cutter 21 contacts the film and breaks the air bubbles, completing the rubber calendering bubble-breaking process. The blade is ground flat to avoid the sharp edge of the blade cutting the film. In cases where the cutter is deep, it protects the roller surface. At the same time, the distance between the blades ensures that the film remains connected after the air bubble is punctured, preventing the film from separating from the cutter line due to continuous cuts. This ensures that the product is not missing any glue. Unscrewing the wing nut and pulling the pin 18 out of the connecting socket allows the connecting block 17 to be moved out of the connecting slot, facilitating the replacement and maintenance of the air bubble cutter 21 and improving convenience. When the sliding block 4 moves, it slides on the guide rod 12. At the same time, the sliding block 4 drives the guide slider 15 to slide on the guide support rod 14, guiding and limiting it, improving structural strength, and ensuring stability during operation. The tie rod 11 increases the connection strength between the fixed plate 5 and the calender frame 1, ensuring stability during use.

[0021] like Figures 1 to 5 As shown, this utility model discloses a rubber calendering bubble-splitting device. During operation, a fixed arm 20 that meets processing requirements is selected, allowing the bubble cutter 21 to contact the rubber sheet and break the bubbles, completing the rubber calendering bubble-splitting process. The flat-ground blade avoids the situation where a sharp blade cuts the rubber sheet too deeply, thus protecting the roller surface. Simultaneously, the distance between the blade teeth ensures that the rubber sheet remains connected after breaking the bubbles, preventing continuous cuts that could cause the rubber sheet to separate at the cutting line, thereby ensuring no rubber shortage in the product. The drive motor 6 is activated, driving the turntable 7 to rotate. The turntable 7, through the rotating shaft 10, moves the rocker arm 9, which in turn pulls the fixed rod 3 and the sliding block through the connecting seat 8. 4. When the fixed rod 3 moves to the left within the adjustment groove, it drives the sliding disk 24 to slide on the slide rod 22, compressing the spring 25. When the fixed rod 3 moves to the right, the elastic force of the spring 25 pushes the sliding disk 24 to slide on the slide rod 22, thereby enabling the fixed rod 3 to move back and forth, achieving the function of drawing a serpentine curve on the thin film and continuously and evenly breaking the bubble. When the sliding block 4 moves, it slides on the guide rod 12. At the same time, the sliding block 4 drives the guide slider 15 to slide on the guide support rod 14, guiding and limiting it. Unscrewing the wing nut and pulling the pin 18 out of the connecting socket allows the connecting plug 17 to be moved out of the connecting slot, facilitating the replacement and maintenance of the bubble cutter 21.

[0022] The drive motor 6 of the rubber calendering bubble-cutting device of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
