Description

Technical Field

[0001] This application relates to the field of tape production technology, and in particular to a roller die-cutting device with automatic waste removal function. Background Technology

[0002] A rotary die-cutting machine is a type of cutting machine. Rotary die-cutting rollers were first used in the printing industry, especially in the cigarette packaging industry. They are a high-efficiency die-cutting tool that can replace flatbed die-cutting. They are mainly used for die-cutting (full cut, half cut) of some non-metallic materials. By applying a certain pressure through the printing plate, the printed material or cardboard is cut into a certain shape.

[0003] In current roller die-cutting equipment, when the compacting roller is used to transport, compact, and die-cut strip products, if the strip product is an adhesive product such as tape, waste material from the product die-cutting will stick to the compacting roller. With prolonged use, the sticky waste material will accumulate on the compacting roller, eventually causing adverse effects on the transport, compaction, and die-cutting processes of the product, thus presenting a deficiency. Utility Model Content

[0004] To address the issue of product waste with adhesive properties easily sticking to the compaction roller, this application provides a roller die-cutting device with an automatic waste removal function.

[0005] The roller die-cutting device with automatic waste removal function provided in this application adopts the following technical solution:

[0006] A roller die-cutting device with automatic waste removal function includes a base plate, upright plates, rollers, and a main shaft. Multiple die-cutting blades are circumferentially arranged on the rollers. The axis of the rollers is parallel to the axis of the main shaft and is located above the main shaft. The upright plates are disposed on the base plate and located at both ends of the main shaft. Slider blocks are rotatably disposed at both ends of the rollers and both ends of the main shaft. The sliders slide in cooperation with the upright plates. Vertical lifting grooves for sliding the sliders are provided on the upright plates. A scraper is mounted between two upright plates and is attached to the surface of the rollers. A drive assembly is provided on the upright plates to drive the rollers and the main shaft to rotate. The product passes between the rollers and the main shaft. A clamping assembly is provided on the upright plates to clamp the rollers onto the main shaft.

[0007] By adopting the above technical solution, the worker first passes the product between the roller and the main shaft, then adjusts the clamping force between the roller and the main shaft on the product through the clamping component, and then drives the roller and the main shaft to rotate through the drive component. The die-cutting blade on the rotating roller performs die-cutting on the product. The waste material generated by the product die-cutting will stick to the roller and rotate with the roller. The scraper will scrape off the product waste stuck to the roller, thereby reducing the impact of product die-cutting waste on the subsequent die-cutting of the product.

[0008] Optionally, a pressure roller is rotatably mounted between the two upright plates. The axis of the pressure roller is parallel to the axis of the main shaft. The pressure roller is located on both sides of the main shaft and below the main shaft. The product is conveyed in the sequence of the pressure roller, the main shaft, the roller, and the pressure roller.

[0009] By adopting the above technical solution, the strip product can be better attached to the circumferential outer wall of the main shaft, which facilitates the die-cutting blade on the roller to accurately die-cut the product and improves the die-cutting accuracy.

[0010] Optionally, a waste collection box is provided between the two upright plates, and the waste collection box is located below the scraper.

[0011] By adopting the above technical solution, the scraper will scrape the waste material off the roller and it will accumulate in the waste collection box. Workers can clean the waste collection box regularly, which helps to reduce the impact of the scraped waste material on the die-cutting effect of the roller on the product.

[0012] Optionally, the clamping assembly includes a sealing plate disposed on the upright plate, a clamping rod threadedly connected to the sealing plate, a pressure block slidably disposed on the lifting groove on the upright plate, the pressure block being located above the roller, the pressure block being rotatably disposed on the clamping rod, and an anti-loosening block threadedly connected to the clamping rod on the side of the sealing plate facing away from the pressure block, the anti-loosening block being used to abut against the sealing plate.

[0013] By adopting the above technical solution, the worker turns the clamping rod, which pushes the pressure block down to press the slider at the end of the roller, thereby pressing the product onto the main shaft, which facilitates the die-cutting blade on the roller to die-cut and transport the product.

[0014] Optionally, the clamping rod is provided with a rotating disk.

[0015] By adopting the above technical solution, it is beneficial to reduce the difficulty for workers to rotate the clamping rod.

[0016] Optionally, the drive assembly includes a drive motor mounted on the base plate and electrically connected to the control system, a drive gear coaxially mounted on the main shaft, a driven gear coaxially mounted on the roller, the drive gear and the driven gear meshing with each other, and a first reduction gearbox for transmitting torque is provided between the output shaft of the drive motor and the main shaft.

[0017] By adopting the above technical solution, the control system starts the drive motor, and the output shaft of the drive motor drives the main shaft to rotate through the first reduction gearbox. The main shaft drives the roller to rotate synchronously through the driving gear and the driven gear, so that the roller can perform die-cutting on the product, which helps to improve the die-cutting accuracy of the product.

[0018] Optionally, the drive assembly includes a die-cutting motor mounted on the base plate and electrically connected to the control system. A second reduction gearbox for transmitting torque is provided between the output shaft of the die-cutting motor and the main shaft. A transmission component is provided between the roller and the main shaft, and the transmission component is used to drive the roller and the main shaft to rotate synchronously.

[0019] By adopting the above technical solution, the control system starts the die-cutting motor, and the output shaft of the die-cutting motor drives the main shaft to rotate through the second reduction gearbox. At the same time, the transmission component drives the roller and the main shaft to rotate synchronously.

[0020] Optionally, the pressure block is fixedly mounted on the slider on the roller. The transmission component includes a first synchronous wheel coaxially mounted on the roller and a second synchronous wheel coaxially mounted on the main shaft. An adjusting block is slidably mounted on the upright plate between the main shaft and the roller. A third synchronous wheel is rotatably mounted on the adjusting block. A synchronous belt is wound around the first, second, and third synchronous wheels. An adjusting groove for the adjusting block to slide is provided on the upright plate. A compression spring supports the adjusting block between the side of the adjusting block facing the main shaft and the adjusting groove.

[0021] By adopting the above technical solution, when the worker tightens the clamping rod, the pressure block drives the slider at the end of the roller to slide, thereby adjusting the distance between the roller and the main shaft. During this process, the compression spring continuously deforms, thereby adjusting the tension of the synchronous belt wound on the first, second and third synchronous pulleys. When the main shaft rotates, the synchronous belt can drive the rollers at different positions to rotate synchronously, thereby adapting to the die-cutting of strip products of different thicknesses.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The worker first passes the product between the roller and the main shaft. Then, the clamping force between the roller and the main shaft on the product is adjusted by the clamping component. Then, the drive component drives the roller and the main shaft to rotate. The die-cutting blade on the rotating roller die-cuts the product. The waste material generated by the product die-cutting will stick to the roller and rotate with the roller. The scraper will scrape off the product waste stuck to the roller, thereby reducing the impact of the product die-cutting waste on the subsequent die-cutting of the product.

[0024] 2. The control system starts the drive motor. The output shaft of the drive motor drives the main shaft to rotate through the first reduction gearbox. The main shaft drives the roller to rotate synchronously through the drive gear and the driven gear, so that the roller can perform die-cutting on the product, which helps to improve the die-cutting accuracy of the product.

[0025] 3. When the worker tightens the clamping rod, the pressure block drives the slider at the end of the roller to slide, thereby adjusting the distance between the roller and the main shaft. During this process, the compression spring continuously deforms, thereby adjusting the tension of the synchronous belts wound on the first, second, and third synchronous pulleys. When the main shaft rotates, the synchronous belt can drive the rollers at different positions to rotate synchronously, thus adapting to the die-cutting of strip products of different thicknesses.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a roller die-cutting device with automatic waste removal function.

[0033] Example 1

[0034] Reference Figure 1 A roller die-cutting device with automatic waste removal function includes a base plate 1, a vertical plate 2, a roller 3 and a main shaft 4. The roller 3 is integrally formed with multiple die-cutting blades 5 in the circumferential direction. The axis of the roller 3 is parallel to the axis of the main shaft 4. The roller 3 is located above the main shaft 4. The vertical plate 2 is welded to the base plate 1 and located at both ends of the main shaft 4.

[0035] Reference Figure 1 and Figure 2 Both ends of the roller 3 and both ends of the main shaft 4 are rotatably arranged with sliders 6. The sliders 6 are slidably engaged with the vertical plate 2. The vertical plate 2 is vertically provided with lifting grooves 7 for the sliders 6 to slide. A scraper 8 is mounted between the two vertical plates 2. The scraper 8 is attached to the surface of the roller 3. A waste collection box 12 is mounted between the two vertical plates 2. The waste collection box 12 is located below the scraper 8. A cleaning roller brush 14 is rotatably mounted between the two vertical plates 2.

[0036] Reference Figure 1 and Figure 2 The cleaning roller brush 14 is used to sweep the product waste on the scraper 8 to the waste collection box 12. The cleaning motor 15, which is electrically connected to the control system, is bolted on the upright plate 2. The cleaning roller brush 14 is coaxially welded to the output shaft of the cleaning motor 15. The pressure roller 11 is rotatably mounted between the two upright plates 2. The axis of the pressure roller 11 is parallel to the axis of the main shaft 4. The pressure roller 11 is located on both sides of the main shaft 4.

[0037] Reference Figure 1 and Figure 2 The pressure roller 11 is located below the main shaft 4. The strip product is conveyed in the order of pressure roller 11, main shaft 4, roller 3, and pressure roller 11. The vertical plate 2 is equipped with a drive assembly 9 that drives the roller 3 and the main shaft 4 to rotate. The product passes between the roller 3 and the main shaft 4. The vertical plate 2 is equipped with a pressing assembly 10, which is used to press the roller 3 onto the main shaft 4.

[0038] The worker first rotates the rotating disc 13, which drives the pressure block 103 away from the roller 3 via the pressure rod 102. Then, the worker passes the strip product through the pressure roller 11, the main shaft 4, the roller 3, and the pressure roller 11 in sequence. After that, the worker tightens the rotating disc 13, which drives the pressure block 103 to abut against the slider 6 at the end of the roller 3 via the pressure rod 102, thereby pressing the strip product onto the main shaft 4. Then, the worker tightens the anti-loosening block 104.

[0039] Reference Figure 1 and Figure 2 The clamping assembly 10 includes a sealing plate 101 bolted to the top of the upright plate 2. A vertical clamping rod 102 is threaded onto the sealing plate 101. A pressure block 103 is vertically slidably arranged on the lifting groove 7 on the upright plate 2. The pressure block 103 is located above the roller 3 and is rotatably connected to the end of the clamping rod 102. A rotating disk 13 is welded onto the clamping rod 102 on the side of the sealing plate 101 facing away from the pressure block 103. An anti-loosening block 104 is threaded onto the clamping rod 102 on the side of the sealing plate 101 facing away from the pressure block 103. The anti-loosening block 104 is used to abut against the sealing plate 101.

[0040] Reference Figure 1 and Figure 2 The drive assembly 9 includes a drive motor 91 bolted to the base plate 1 and electrically connected to the control system. A drive gear 92 is coaxially bolted to the main shaft 4, and a driven gear 93 is coaxially bolted to the roller 3. The drive gear 92 and the driven gear 93 mesh with each other. A first reduction gearbox 94 for transmitting torque is arranged between the output shaft of the drive motor 91 and the main shaft 4.

[0041] Then the control system starts the drive motor 91. The output shaft of the drive motor 91 drives the main shaft 4 to rotate through the first reduction gearbox 94. The main shaft 4 drives the driven gear 93 to rotate through the drive gear 92. The driven gear 93 drives the roller 3 to rotate synchronously, so that the die-cutting blade 5 on the roller 3 can die-cut the product. The waste material generated by the product die-cutting will stick to the roller 3.

[0042] The product waste adhering to the roller 3 will rotate with the roller 3, and the scraper 8 will scrape off the product waste adhering to the roller 3. The product waste will accumulate on the scraper 8. Then the control system starts the cleaning motor 15. The output shaft of the cleaning motor 15 drives the cleaning roller brush 14 to rotate. The rotating cleaning roller brush 14 sweeps the product waste on the scraper 8 into the waste collection box 12.

[0043] The implementation principle of Example 1 is as follows: The worker first rotates the rotating disk 13, and the rotating disk 13 drives the pressure block 103 away from the roller 3 through the pressure rod 102. Then the worker passes the strip product through the pressure roller 11, the main shaft 4, the roller 3, and the pressure roller 11 in sequence. After that, the worker tightens the rotating disk 13, and the rotating disk 13 drives the pressure block 103 to abut against the slider 6 at the end of the roller 3 through the pressure rod 102, so that the roller 3 presses the strip product onto the main shaft 4. Then the anti-loosening block 104 is tightened.

[0044] Then the control system starts the drive motor 91. The output shaft of the drive motor 91 drives the main shaft 4 to rotate through the first reduction gearbox 94. The main shaft 4 drives the driven gear 93 to rotate through the drive gear 92. The driven gear 93 drives the roller 3 to rotate synchronously, so that the die-cutting blade 5 on the roller 3 can die-cut the product. The waste material generated by the product die-cutting will stick to the roller 3.

[0045] The product waste adhering to the roller 3 will rotate with the roller 3, and the scraper 8 will scrape off the product waste adhering to the roller 3. The product waste will accumulate on the scraper 8. Then the control system starts the cleaning motor 15. The output shaft of the cleaning motor 15 drives the cleaning roller brush 14 to rotate. The rotating cleaning roller brush 14 sweeps the product waste on the scraper 8 into the waste collection box 12.

[0046] Example 2

[0047] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that the drive assembly 9 includes a die-cutting motor 95 bolted to the base plate 1 and electrically connected to the control system. A second reduction gearbox 96 for transmitting torque is arranged between the output shaft of the die-cutting motor 95 and the main shaft 4. A transmission component 97 is arranged between the roller 3 and the main shaft 4. The transmission component 97 is used to drive the roller 3 and the main shaft 4 to rotate synchronously.

[0048] Reference Figure 3 and Figure 4 The pressure block 103 is bolted to the slider 6 on the roller 3. The transmission component 97 includes a first synchronous wheel 971 coaxially bolted to the roller 3 and a second synchronous wheel 972 coaxially bolted to the main shaft 4. An adjusting block 973 is horizontally slidably arranged on the vertical plate 2 between the main shaft 4 and the roller 3.

[0049] Reference Figure 3 and Figure 4 A third synchronous pulley 974 is rotatably connected to the adjusting block 973. A synchronous belt 975 is wound around the first synchronous pulley 971, the second synchronous pulley 972 and the third synchronous pulley 974. An adjusting groove 976 is provided on the vertical plate 2 for the adjusting block 973 to slide. The cross-section of both the adjusting block 973 and the adjusting groove 976 is T-shaped. A compression spring 977 is provided between the side of the adjusting block 973 facing the main shaft 4 and the adjusting groove 976.

[0050] The implementation principle of Example 2 is as follows: When the worker turns the clamping rod 102, the pressure block 103 drives the slider 6 at the end of the roller 3 to slide, thereby adjusting the distance between the roller 3 and the main shaft 4. During this process, the compression spring 977 continuously deforms, thereby adjusting the tension of the synchronous belt 975 wound on the first synchronous pulley 971, the second synchronous pulley 972 and the third synchronous pulley 974.

[0051] Then the control system starts the die-cutting motor 95. The output shaft of the die-cutting motor 95 drives the main shaft 4 to rotate through the second reduction gearbox 96. The main shaft 4 drives the second synchronous pulley 972 to rotate synchronously. The second synchronous pulley 972 drives the first synchronous pulley 971 to rotate through the synchronous belt 975. The first synchronous pulley 971 drives the roller 3 to rotate synchronously, so that the main shaft 4 and the roller 3 rotate synchronously, thereby adapting to the die-cutting of strip products of different thicknesses.
