Description

Technical Field

[0001] The utility model relates to a material strip rolling cutting device. Background Art

[0002] In order to realize the automatic change of die-cutting equipment, we have designed a continuous material splicing device. The basic principle is to cut the working material roll and the backup material roll, and then glue the remaining sections of the working material roll and the backup material roll together.

[0003] The material strip rolling and cutting device is a key part of the continuous material splicing device. The material strip rolling and cutting device is used to cut the working material strip or the spare material strip. The reserved section of the spare material strip is connected to the reserved section of the working material strip, thereby forming a new working material strip between the material strip rolling and cutting device and the knife plate, or the material strip rolling and cutting device and the knife plate are left empty to place a new spare material strip.

[0004] The design requirements of the strip rolling cutting device are: 1. It can achieve rapid cutting of the strip and ensure stable and reliable cutting effect. Utility Model Content

[0005] The purpose of the utility model is to provide a material strip rolling cutting device that can achieve rapid and stable cutting of the material strip in order to solve the above problems.

[0006] In order to achieve the above-mentioned purpose, the utility model discloses a material strip rolling cutting device, which includes a frame, a vertically arranged knife plate is provided on the frame, a straight shearing edge is provided at the vertical first side edge of the knife plate, and a sliding cutting bracket driven longitudinally by a power device is installed on the frame at a position on the lateral side of the knife plate, and a rolling cutting wheel that can rotate around a vertical axis is installed on the sliding cutting bracket. The longitudinal movement of the sliding cutting bracket is used to make the rolling cutting wheel cooperate with the straight shearing edge to shear the material strip.

[0007] After adopting the above structure, when the power device drives the sliding cutting bracket to slide longitudinally, the rolling cutting wheel and the linear shearing edge on the knife plate can cooperate to form a shearing force, thereby cutting the material strip.

[0008] Preferably, the sliding cutting bracket is provided with an axle, and the rolling cutting wheel is rotatably mounted on the axle. The axle is provided with a first spring for applying a force to the rolling cutting wheel toward the second vertical side. The edge of the vertical first side of the blade is provided with an avoidance notch for the rolling cutting wheel to enter at a position close to the first longitudinal side. The second longitudinal side of the avoidance notch has an inclined guide surface. When the sliding cutting bracket moves longitudinally, the inclined guide surface is used to guide the rolling cutting wheel to move along the axle toward the first vertical side, thereby entering the first vertical side of the linear shearing blade. With the above structure, each time the cutting operation is performed, the rolling cutting wheel first enters the avoidance notch horizontally, and then moves longitudinally along the inclined guide surface to the linear shearing blade. In this way, each time the cutting operation is performed, the circular shearing blade 21 on the rolling cutting wheel can be well fitted with the linear shearing blade on the blade, ensuring that the material strip rolling cutting device has a good shearing effect.

[0009] Preferably, a wheel frame is mounted on the sliding cutting bracket, and the wheel axle and the rolling cutting wheel are arranged on the wheel frame. After adopting the above structure, the wheel frame is mounted on the sliding cutting bracket, which facilitates the installation of the wheel axle and the rolling cutting wheel.

[0010] Preferably, a bearing is installed within the cutting wheel, which is slidably mounted on the wheel axle, and the two ends of the first spring respectively abut against the wheel frame and the bearing. With this structure, the cutting wheel is rotatably and slidably mounted on the wheel axle, and the first spring exerts a vertical force on the cutting wheel, allowing the cutting wheel to fit well with the linear shear blade, ensuring that the strip cutting device achieves a good shearing effect.

[0011] Preferably, the wheel frame is mounted on the sliding cutting bracket in a manner capable of transverse sliding motion, and a second spring is provided between the sliding cutting bracket and the wheel frame for causing the rolling cutting wheel to laterally approach the blade. With this structure, the rolling cutting wheel can slide laterally and is subject to the force of the second spring, allowing the rolling cutting wheel to have a certain amount of transverse movement during rolling cutting. This not only allows the rolling cutting wheel to be closer to the blade and exert a certain amount of pressure, but also improves the cutting effect on the material strip.

[0012] Preferably, the sliding cutting bracket is provided with a first sliding rail extending transversely, and the wheel frame is provided with a first slider, the first slider being in sliding engagement with the first sliding rail. With the above structure, the wheel frame and the rolling cutting wheel mounted thereon can maintain longitudinal stability with the sliding cutting bracket when they move transversely.

[0013] Preferably, the sliding bracket is provided with a transversely extending guide rod, and the wheel frame is provided with a guide hole. The guide rod passes through the guide hole, and the second spring is sleeved on the guide rod. The ends of the second spring sleeve respectively abut against the sliding bracket and the wheel frame. With this structure, the guide rod cooperates with the guide hole to ensure that the wheel frame can move laterally relative to the sliding bracket while maintaining the position of the second spring, thereby generating a stabilizing force on the wheel frame.

[0014] Preferably, the frame is equipped with a sliding mounting frame that is driven by a power device to slide laterally, the sliding cutting bracket is mounted on the sliding mounting frame for longitudinal sliding, a second sliding rail extending laterally is mounted on the frame, a second slider is mounted on the sliding mounting frame, and the second slider slides in cooperation with the second sliding rail; a third sliding rail extending longitudinally is mounted on the sliding mounting frame, and the sliding cutting bracket is mounted on the third slider, and the third slider slides in cooperation with the third sliding rail. With the above structure, the cooperation between the second sliding rail and the second slider enables the sliding mounting frame to slide laterally relative to the frame, thereby moving the rolling cutting wheel to the side laterally away from the blade, forming a transverse spacing between the rolling cutting wheel and the blade, and allowing a new material strip to pass through the transverse spacing to become a working material strip or a spare material strip.

[0015] Preferably, an elastic sleeve is provided on the outer circumference of the rolling wheel. With the above structure, while the material strip is being cut, the elastic sleeve can roll the remaining section of the material strip so that it adheres to the material strip with the tape on the other side.

[0016] Preferably, the second vertical side surface near the rolling wheel is provided with a conical inner recess with a concave center, and the intersection of the conical inner recess and the outer peripheral surface of the rolling wheel forms a circular shearing edge. With this structure, the intersection of the conical inner recess and the outer peripheral surface of the rolling wheel forms a circular shearing edge, thereby greatly improving the shearing effect on the material strip.

[0017] In summary, the beneficial effects of the present invention are as follows: the material strip rolling cutting device uses a rolling cutting method to cut the material strip, and the cutting speed is relatively fast. During the cutting process, the edge of the rolling cutting wheel always maintains contact with the straight shear blade, and the cutting effect is relatively good. By utilizing the sliding fit between the rolling cutting wheel and the wheel shaft and the vertical force of the first spring, in conjunction with the avoidance notch, inclined guide surface and other structures on the blade, the circular shear blade 21 on the rolling cutting wheel can fit well with the straight shear blade on the blade during each cutting operation, ensuring a good shearing effect every time. While the material strip is being cut, the elastic sleeve can roll the retained section of the material strip so that it adheres to the material strip with tape on the other side.

[0023] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] Reference Figure 1 、 Figure 2 In some embodiments of the present invention, a material strip rolling cutting device includes a frame 1, a vertically arranged blade 2 is provided on the frame 1, and a linear shearing edge 3 is provided on a first vertical side of the blade 2. A sliding cutting bracket 4 driven longitudinally by a power device is installed on the frame 1 at a position laterally to the blade 2. The sliding cutting bracket 4 is mounted with a rolling cutting wheel 5 that can rotate about a vertical axis. The sliding cutting bracket 4 moves longitudinally to enable the rolling cutting wheel 5 to cooperate with the linear shearing edge 3 to shear the material strip. When the power device drives the sliding cutting bracket 4 to slide longitudinally, the rolling cutting wheel 5 cooperates with the linear shearing edge 3 on the blade 2 to generate a shearing force, thereby cutting the material strip.

[0025] Since the sliding mounting frame 16 can slide laterally to move the rolling wheel 5 laterally away from the blade 2, it is difficult to ensure that the circular shearing edge 21 of the rolling wheel 5 will cooperate well with the linear shearing edge 3 on the blade 2 when the rolling wheel 5 next moves laterally closer to the blade 2. The present utility model further improves on this problem.

[0026] Reference Figure 1 、 Figure 4In a further improvement of the present invention, a wheel axle 6 is provided on the sliding cutting bracket 4, and a rolling cutting wheel 5 is rotatably mounted on the wheel axle 6. A first spring 7 is provided on the wheel axle 6 for applying a force to the rolling cutting wheel 5 toward the second vertical side. A clearance notch 8 for the rolling cutting wheel 5 to enter is provided at a portion of the vertical first side edge of the blade 2 near the first longitudinal side. The longitudinal second side of the clearance notch 8 has an inclined guide surface 9. When the sliding cutting bracket 4 moves longitudinally, the inclined guide surface 9 is used to guide the rolling cutting wheel 5 to move along the wheel axle 6 toward the first vertical side and thus enter the first vertical side of the linear shearing blade 3. During each cutting operation, the rolling cutting wheel 5 first enters the clearance notch 8 horizontally, and then moves longitudinally along the inclined guide surface 9 to the linear shearing blade 3. In this way, the circular shearing blade 21 on the rolling cutting wheel 5 can be well aligned with the linear shearing blade 3 on the blade 2 during each shearing operation, ensuring that the material strip rolling cutting device has a good shearing effect.

[0027] Reference Figure 1 、 Figure 3 In order to better install the rolling wheel 5, a wheel frame 10 is installed on the sliding cutting bracket 4, and the wheel axle 6 and the rolling wheel 5 are arranged on the wheel frame 10. By installing the wheel frame 10 on the sliding cutting bracket 4, the installation of the wheel axle 6 and the rolling wheel 5 is facilitated.

[0028] Reference Figure 3 To ensure that the cutting wheel 5 is rotatably and slidably mounted on the axle 6 and that the first spring 7 exerts a vertical force on the cutting wheel 5, a bearing 11 is installed within the cutting wheel 5. The bearing 11 is slidably mounted on the axle 6. The two ends of the first spring 7 respectively abut against the wheel frame 10 and the bearing 11. With this structure, the cutting wheel 5 is rotatably and slidably mounted on the axle 6, and the first spring 7 exerts a vertical force on the cutting wheel 5. This allows the cutting wheel 5 to fit snugly with the linear shear blade 3, ensuring that the strip cutting device achieves a good shearing effect.

[0029] Reference Figure 1 、 Figure 2 、 Figure 3 In order to make the wheel frame 10 laterally close to the blade 2 and achieve a better shearing effect, the wheel frame 10 is mounted on the sliding cutting bracket 4 in a manner that allows it to slide laterally. A second spring 12 is provided between the sliding cutting bracket 4 and the wheel frame 10 to allow the rolling cutting wheel 5 to laterally approach the blade 2. The rolling cutting wheel 5 can slide laterally and is subject to the force of the second spring 12, so that the rolling cutting wheel 5 has a certain amount of lateral movement during rolling cutting. Not only can the rolling cutting wheel 5 be closer to the blade 2 and exert a certain amount of pressure, but the cutting effect on the material strip is also better.

[0030] Reference Figure 2To ensure that the wheel frame 10 and the rolling wheel 5 mounted thereon remain stable in the longitudinal direction relative to the sliding bracket 4 during transverse movement, a first sliding rail 13 extending laterally is mounted on the sliding bracket 4, and a first slider is mounted on the wheel frame 10, which slides in engagement with the first sliding rail 13. With this structure, the wheel frame 10 and the rolling wheel 5 mounted thereon remain stable in the longitudinal direction relative to the sliding bracket 4 during transverse movement.

[0031] Reference Figure 1 、 Figure 3 In order to maintain the force exerted by the second spring 12 on the wheel frame 10 while maintaining its ability to move laterally relative to the sliding bracket 4, a laterally extending guide rod 14 is provided on the sliding bracket 4. A guide hole 15 is provided on the wheel frame 10. The guide rod 14 passes through the guide hole 15, and the second spring 12 is sleeved onto the guide rod 14. The ends of the second spring 12 sleeve respectively abut against the sliding bracket 4 and the wheel frame 10. The guide rod 14 cooperates with the guide hole 15 to maintain the position of the second spring 12 while ensuring that the wheel frame 10 can move laterally relative to the sliding bracket 4, thereby exerting a stable force on the wheel frame 10.

[0032] Reference Figure 4 In order to facilitate the passage of the working material strip or the spare material strip between the rolling wheel 5 and the blade 2, a sliding mounting frame 16 driven by a power device for transverse sliding is installed on the frame 1. The sliding cutting bracket 4 is longitudinally slidably mounted on the sliding mounting frame 16. A second slide rail 17 extending transversely is installed on the frame 1. A second slider is mounted on the sliding mounting frame 16, and the second slider slides in sliding engagement with the second slide rail 17. A third slide rail 18 extending longitudinally is mounted on the sliding mounting frame 16, and a third slider is mounted on the sliding cutting bracket 4, and the third slider slides in sliding engagement with the third slide rail 18. The cooperation between the second slide rail 17 and the second slider enables the sliding mounting frame 16 to slide transversely relative to the frame 1, thereby allowing the rolling wheel 5 to move to the side lateral away from the blade 2, forming a transverse spacing between the rolling wheel 5 and the blade 2, through which a new material strip can pass to become the working material strip or the spare material strip.

[0033] refer to Figure 3 In order to roll the remaining section of the tape so that it can be attached to the tape on the other side, an elastic sleeve 19 is provided on the outer circumference of the rolling wheel 5. While the tape is being cut, the elastic sleeve 19 can roll the remaining section of the tape so that it can be attached to the tape on the other side.

[0034] Reference Figure 3To improve the shearing effect of the rolling wheel 5, a conical recessed portion 20 with a concave center is provided on the second vertical side end surface near the rolling wheel 5. A circular shearing edge 21 is formed at the intersection of the conical recessed portion 20 and the outer peripheral surface of the rolling wheel 5. The circular shearing edge 21 is formed at the intersection of the conical recessed portion 20 and the outer peripheral surface of the rolling wheel 5, thereby greatly improving the shearing effect on the material strip.

[0035] The usage of this utility model is as follows:

[0036] First, the power device drives the sliding mounting frame 16 to slide laterally, so that the rolling wheel 5 moves to the lateral side close to the blade 2, and the rolling wheel 5 partially enters the avoidance gap 8.

[0037] Subsequently, the power device drives the sliding cutting bracket 4 to move longitudinally, and the inclined guide surface 9 of the vertical second end face of the rolling cutting wheel 5 slides. As the rolling cutting wheel 5 gradually approaches the inclined guide surface 9 from the avoidance gap 8, the inclined guide surface 9 forces the rolling cutting wheel 5 to overcome the force of the first spring 7 and move toward the vertical first side until the rolling cutting wheel 5 moves longitudinally to the linear shearing blade 3. The edge of the vertical second end face of the rolling cutting wheel 5 forms a shearing force with the linear shearing blade 3, thereby cutting the material strip.

[0038] After the material strip is cut, the power device drives the sliding mounting frame 16 to slide horizontally, so that the rolling wheel 5 moves to the lateral side away from the blade 2, and a horizontal spacing space is formed between the rolling wheel 5 and the blade 2, so that the new material strip can pass through the horizontal spacing space to become a working material strip or a spare material strip.

[0039] Since the sliding mounting frame 16 can slide laterally so that the rolling cutting wheel 5 moves laterally away from the knife plate 2, it is difficult to ensure that the circular shearing edge 21 of the rolling cutting wheel 5 will cooperate well with the straight shearing edge 3 on the knife plate 2 when the rolling cutting wheel 5 approaches the knife plate 2 laterally next time. The utility model cleverly designs a structure in which the rolling cutting wheel 5 slides vertically along the wheel shaft 6 and uses the first spring 7 to apply a force to the rolling cutting wheel 5 toward the second vertical side, and then cooperates with the avoidance notch 8, the inclined guide surface 9 and other structures on the knife plate 2 to make the rolling cutting wheel 5 first enter the avoidance notch 8 laterally, and then move longitudinally along the inclined guide surface 9 to the straight shearing edge 3. In this way, the circular shearing edge 21 on the rolling cutting wheel 5 can fit well with the straight shearing edge 3 on the knife plate 2 each time shearing is performed, ensuring that the material strip rolling cutting device has a good shearing effect.

[0040] An elastic sleeve 19 is provided on the outer circumference of the rolling wheel 5. While cutting the material strip, the elastic sleeve 19 can roll the remaining section of the material strip so that it adheres to the material strip with tape on the other side.
