Description

Technical Field

[0001] The present application relates to the field of automated cutting, printing and embossing equipment, and in particular to a multi-traction device for cutting, printing or embossing and equipment using the device. Background Art

[0002] The traction device is used as a power source to pull materials in continuous sheet processing equipment. In continuous sheet processing equipment, the traction device continuously pulls the materials. During the forward conveyance of the materials, the materials pass through the processing rollers and are processed by the cutting, printing and embossing components on the processing rollers.

[0003] Regarding the above-mentioned related technologies, the applicant believes that the following defects exist: since the processing roller has a limited linear speed for processing materials, when the linear speed is too fast, incomplete cutting, printing and embossing will occur, and thus the speed at which the equipment processes materials is limited. Utility Model Content

[0004] In order to improve processing efficiency, the present application provides a multi-traction device for cutting, printing or embossing and equipment using the device.

[0005] In a first aspect, the present application provides a multi-traction device for cutting, printing or embossing, which adopts the following technical solution:

[0006] A multi-traction device for cutting, printing or embossing comprises a frame, a processing roller located on the frame, at least two bottom rollers located on the frame for cooperating with the processing roller, and at least one group of traction power components for variable speed traction of materials and at least one group of relay power components for cooperating with variable speed transmission of materials, wherein the processing roller is provided with at least one processing area and at least one non-processing area.

[0007] By adopting the above technical scheme, when the processing roller rotates to the position where the processing area and a bottom roller cooperate, the relay power assembly drives the material to be transported at the same speed as the surface linear speed of the processing roller, and the processing roller processes the material to form a processing section. When the processing roller rotates to the position where the non-processing area cooperates with the bottom roller, the speed of the relay power assembly is changed, so that when the processing roller rotates to the next processing area and cooperates with the bottom roller, the relay power assembly drives the material to be transported forward by a distance equal to the circumferential length of the processing area, so that an unprocessed section is formed on the surface of the material. When the processing roller rotates to the non-processing area and cooperates with another bottom roller, the traction power assembly adjusts the conveying speed so that the processing roller rotates to the processing area and cooperates with the bottom roller, and the unprocessed section of the material reaches the position between the processing roller and the bottom roller. Then the conveying speed of the traction power assembly is reduced, so that the surface linear speed and the surface linear speed of the processing roller rotate at the same state, and the unprocessed section is processed to form a processing section. During the whole process, the average speed of the traction power assembly driving the material to be transported is greater than the surface linear speed of the processing roller, and the processing of the material by the processing roller is carried out in multiple stages. Therefore, with the speed change coordination of the relay power assembly and the traction power assembly, the processing efficiency can be improved while the linear speed of the processing roller surface remains unchanged.

[0008] Preferably, the traction power assembly includes a traction pressing roller and a traction auxiliary roller for cooperating to press the material, a traction motor for driving the traction pressing roller to rotate, and a traction pressure source for applying opposite forces to the traction auxiliary roller and the traction pressing roller.

[0009] By adopting the above technical solution, the traction pressure source provides a force, so that the traction auxiliary roller and the traction pressing roller approach each other to press the material, and the traction pressing roller is driven to rotate by the traction motor.

[0010] Preferably, the traction pressure source is a traction cylinder, and traction swing arms are installed at both ends of the traction auxiliary roller. The middle part of the traction swing arm is rotatably connected to the traction auxiliary roller, one end of the traction swing arm is rotatably connected to the frame, the position of the traction swing arm away from the frame is rotatably connected to the traction cylinder, and the end of the traction cylinder away from the traction swing arm is rotatably connected to the frame.

[0011] By adopting the above technical solution, the traction cylinder contracts to drive the traction swing arm to rotate, so that the traction auxiliary roller rotatably connected to the traction swing arm moves together, and finally the traction auxiliary roller and the traction clamping roller are brought close to each other and clamped.

[0012] Preferably, the relay power assembly includes a relay pressing roller for cooperating to press the material, and a relay motor for driving the relay pressing roller to rotate.

[0013] By adopting the above technical solution, the relay motor drives the relay pressing roller to rotate to control the speed of the relay conveying material.

[0014] Preferably, the relay power assembly further comprises a relay auxiliary roller for cooperating in compacting the material, and a relay pressure source for applying opposite forces to the relay auxiliary roller and the relay compacting roller.

[0015] By adopting the above technical solution, the relay auxiliary roller and the relay pressing roller are driven by the relay pressure source to approach each other to press the material.

[0016] Preferably, the relay pressure source is a relay cylinder, and relay swing arms are installed at both ends of the relay auxiliary roller. The middle part of the relay swing arm is rotatably connected to the relay auxiliary roller, one end of the relay swing arm is rotatably connected to the frame, the position of the relay swing arm away from the frame is rotatably connected to the relay cylinder, and the end of the relay cylinder away from the relay swing arm is rotatably connected to the frame.

[0017] By adopting the above technical solution, the relay cylinder drives the relay swing arm to swing, so that the relay auxiliary roller on the relay swing arm is pressed against the relay clamping roller under the action of the relay cylinder.

[0018] Preferably, it also includes a relay tensioning assembly, which includes a relay tensioning rail installed on the frame, a relay tensioning movable roller sliding along the relay tensioning rail, and a tensioning power source that drives the relay tensioning movable roller to move along the relay tensioning rail to tension the material.

[0019] By adopting the above technical solution, the relay tensioning movable roller is driven by the tensioning power source to move along the relay tensioning track in the direction of the tensioned material, thereby avoiding the situation where the relay power component drives the material to be transported quickly, while the traction power component drives the material to be transported slowly, causing the material to relax and then overlap, affecting the processing quality.

[0020] Preferably, the relay tensioning assembly further comprises at least one relay tensioning fixed roller rotatably connected to the frame, and each group of relay tensioning assemblies has at least two relay tensioning movable rollers which move synchronously along the relay tensioning track.

[0021] By adopting the above technical solution, the relay tensioning movable roller is arranged to cooperate with the relay tensioning fixed roller, so that the relay tensioning component has greater material storage redundancy, and the relay movable roller only needs a small movement to complete a larger adjustment.

[0022] Preferably, the relay power assembly includes a relay power movable roller and a relay power source for driving the relay power movable roller to move toward or away from the bottom roller.

[0023] By adopting the above technical solution, the relay power active roller is directly pushed to move toward or away from the bottom roller by the relay power source, so as to control the speed of the material passing through the position between the bottom roller and the processing roller. When the processing roller rotates to the position where the processing area and a bottom roller cooperate, the relay power component drives the material to be transported at the same speed as the surface linear speed of the processing roller, and the processing roller processes the material to form a processing section. When the processing roller rotates to the position where the non-processing area cooperates with the bottom roller, the speed of the relay power component is changed, so that when the processing roller rotates to the next processing area and cooperates with the bottom roller, the relay power component drives the material to be transported forward by a distance equal to the circumferential length of the processing area, so that an unprocessed section is formed on the surface of the material. And the relay tensioning component does not need to cooperate to tension the material during the whole process.

[0024] In a second aspect, the present application provides a device, which adopts the following technical solution:

[0025] A device for cutting, printing or embossing, comprising the above-mentioned multi-traction device.

[0026] By adopting the above technical solution, through the cooperation of multiple traction devices and processing rollers, the average speed of the traction power component driving the material conveying during the whole process is greater than the linear speed of the processing roller surface, thereby improving the processing efficiency while keeping the linear speed of the processing roller unchanged.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. During the whole process, the average speed of the material conveyed by the traction power assembly is greater than the linear speed of the processing roller surface, so the processing efficiency can be improved while the linear speed of the processing roller remains unchanged.

[0029] 2. The relay tensioning movable roller is driven by the tensioning power source to move along the relay tensioning track in the direction of the tensioned material, so as to avoid the situation where the relay power component drives the material to be transported quickly, while the traction power component drives the material to be transported slowly, causing the material to relax and then overlap, affecting the processing quality.

[0038] The following is combined with Figure 1-7 This application is described in further detail.

[0039] The embodiments of the present application disclose a multi-traction device for cutting, printing or embossing and an apparatus using the device. The "up", "down", "left" and "right" used in the embodiments are all used to describe the relative directions of the positional relationship and are not limitations of the positional relationship.

[0040] Embodiment 1:

[0041] like Figure 1 As shown, the multi-traction device for cutting, printing or embossing includes a frame 3, a processing roller 1 located on the frame 3, two bottom rollers 4 located on the frame 3 for cooperating with the processing roller 1, a traction power assembly 5 for variable speed traction of materials, a relay power assembly 6 for cooperating with the transmission of materials, and a relay tensioning assembly 7 for tensioning materials. The outer ring of the processing roller 1 is provided with a processing area and a non-processing area, and the coverage of the processing area is larger than the non-processing area. For example, when used for cutting operations, the area on the surface of the processing roller 1 where the magnetic blade skin is attached is the processing area, and the area where the magnetic blade skin is not attached is the non-processing area. The two bottom rollers 4 are located on the left and right sides of the processing roller 1. When the bottom rollers 4 cooperate with the processing area of ​​the processing roller 1, the material is pressed against the processing roller 1, so that the processing roller 1 smoothly performs cutting, printing or embossing on the material. When the bottom rollers 4 cooperate with the non-processing area of ​​the processing roller 1, the material can move between the bottom rollers 4 and the processing roller 1.

[0042] like Figure 1 and Figure 2As shown, the traction power assembly 5 includes a traction pressing roller 8 and a traction auxiliary roller 9 for pressing the material, a traction motor for driving the traction pressing roller 8 to rotate, and a traction cylinder 10 for applying opposite forces to the traction auxiliary roller 9 and the traction pressing roller 8 (the traction cylinder 10 can be replaced by other components for applying pressure), and the traction motor is a servo motor or other motors that can accurately control and adjust the speed. A traction direction-changing roller 11 for adjusting the direction of the material is installed at the lower left position of the traction pressing roller 8 on the frame 3. A traction swing arm 12 is installed at both ends of the traction auxiliary roller 9, one end of the traction swing arm 12 is rotatably connected to the frame 3, the middle part of the traction swing arm 12 is rotatably connected to the traction auxiliary roller 9, the other end of the traction swing arm 12 is rotatably connected to one end of the traction cylinder 10, and the other end of the traction cylinder 10 is rotatably connected to the frame 3. The traction cylinder 10 drives the traction swing arm 12 to swing, so that the traction auxiliary roller 9 is pressed on the traction clamping roller 8 to clamp the material, and then the traction motor drives the traction clamping roller 8 to rotate, so that the material is transported forward at the same speed as the outer ring linear speed of the traction clamping roller 8.

[0043] like Figure 1 and Figure 3 As shown, the relay power assembly 6 includes a relay pressing roller 13 and a relay auxiliary roller 14 for pressing the material, a relay motor for driving the relay pressing roller 13 to rotate, and a relay cylinder 15 (the relay cylinder 15 can be replaced by other components for applying pressure) that exerts opposite forces on the relay auxiliary roller 14 and the relay pressing roller 13. A relay changing roller 22 for adjusting the direction of the material is installed at the lower left position of the relay pressing roller 13 on the frame 3. Relay swing arms 16 are installed at both ends of the relay auxiliary roller 14, one end of the relay swing arm 16 is rotatably connected to the frame 3, the middle part of the relay swing arm 16 is rotatably connected to the relay auxiliary roller 14, the other end of the relay swing arm 16 is rotatably connected to one end of the relay cylinder 15, and the other end of the relay cylinder 15 is rotatably connected to the frame 3. The relay cylinder 15 drives the relay swing arm 16 to swing, so that the relay auxiliary roller 14 is pressed on the relay clamping roller 13 to clamp the material, and then the relay motor drives the relay clamping roller 13 to rotate, so that the material is transported forward at the same speed as the outer ring linear speed of the relay clamping roller 13.

[0044] like Figure 1 and Figure 4 As shown, the relay tensioning assembly 7 includes a relay tensioning rail 17 installed on the frame 3 in the vertical direction, two relay tensioning active rollers 18 fixed on the slider 19 of the relay tensioning rail 17, a relay tensioning fixed roller 20 installed on the frame 3 and located above the relay tensioning rail 17, and a tensioning power source 21 connecting the slider 19 and the lower end of the relay tensioning rail 17. The tensioning power source 21 can be a spring, an elastic belt, or a cylinder or motor screw structure that cooperates with real-time adjustment of the tensioning.

[0045] The direction of the material is as follows: the material enters the position between the bottom roller 4 and the processing roller 1 on the left from left to right, then passes through the relay changing roller 22 downward and then enters the position between the relay pressing roller 13 and the relay auxiliary roller 14 upward; then passes through the relay tensioning active roller 18 on the left downward and then bypasses the relay tensioning fixed roller 20 upward and then bypasses the relay tensioning active roller 18 on the right downward; then the material continues to pass upward between the bottom roller 4 and the processing roller 1 on the right, and finally passes through the traction changing roller 11 downward and then passes upward between the traction pressing roller 8 and the traction auxiliary roller 9 and is led out.

[0046] Specific working process:

[0047] The processing motor drives the processing roller 1 to rotate at a fixed speed. When the processing roller 1 rotates to the position where the processing area and the left bottom roller 4 cooperate, the relay motor drives the relay pressing roller 13 to rotate at the same surface linear velocity as the surface linear velocity of the processing roller 1. At this time, the processing roller 1 processes the material to form a processing section. When the processing roller 1 rotates to the position where the non-processing area cooperates with the left bottom roller 4, the first section of the material surface processing has been completed. The speed of the relay motor is changed so that the processing roller 1 rotates to the next processing area and the left bottom roller 4 cooperates. The relay power assembly 6 drives the material to be transported forward by a distance equal to the circumferential length of the processing area, so that the material surface forms an unprocessed section of the same length as the processing section.

[0048] When the processing roller 1 rotates to the non-processing area and cooperates with the bottom roller 4 on the right, the traction motor adjusts the speed to drive the traction and pressure roller 8 to rotate, so that when the processing roller 1 rotates to the processing area and cooperates with the bottom roller 4 on the right, the unprocessed section of the material reaches the position between the processing roller 1 and the bottom roller 4. Then the speed of the traction motor is changed so that the traction motor drives the traction and pressure roller 8 to rotate at the same surface linear velocity as the surface linear velocity of the processing roller 1, and at this time the unprocessed section is processed to form a processed section.

[0049] During the whole process, the average speed of material conveying is greater than the linear speed of the surface of the processing roller 1, and the processing of the material by the processing roller 1 is carried out in multiple stages. Therefore, with the speed change coordination of the relay power assembly 6 and the traction power assembly 5, the processing efficiency can be improved while the linear speed of the surface of the processing roller 1 remains unchanged.
