Description

Technical Field

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

[0002] In the continuous sheet processing equipment, the material is continuously pulled by the traction device. During the forward conveyance of the material, it passes through the position of the processing roller and is processed by the cutting, printing and embossing components on the processing roller.

[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. Therefore, there is an upper limit speed for the equipment to process materials, and this upper limit cannot be simply broken by increasing the traction speed and equipment operation efficiency. Utility Model Content

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

[0005] In the first aspect, the multi-unit device for cutting, printing or embossing provided by the present application adopts the following technical solution:

[0006] A multi-unit device for cutting, printing or embossing comprises a frame and at least two sets of processing and traction mechanisms located on the frame, each set of the processing and traction mechanisms comprises a processing roller, a bottom roller matched with the processing roller and a traction power assembly for variable speed traction of materials, and 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 material passes through the position between the processing roller and the bottom roller of the first set of processing traction mechanism, and the processing area of ​​the processing roller cooperates with the bottom roller, the traction power assembly drives the material to be transported at the same speed as the surface linear velocity 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 first section of the material surface processing has been completed, and the speed of the traction power assembly to convey the material is increased to form an unprocessed section with a length that is an integer times the processing section. When the material is conveyed to the subsequent processing traction mechanism, when the processing roller of the second set of processing traction mechanism rotates to the position where the non-processing area cooperates with the bottom roller, the traction power assembly adjusts the speed so that when the processing roller rotates to the position where the processing area cooperates with the bottom roller, the unprocessed section of the material reaches the position between the processing roller and the bottom roller. Then the material conveying speed of the traction power assembly is adjusted again, so that the material conveying speed is the same as the surface linear velocity of the processing roller to complete the processing of the unprocessed section. During the whole process, the average speed of the traction power assembly driving the material to be conveyed is greater than the surface linear velocity of the processing roller, and the processing of the material by the processing roller is carried out in multiple stages, so that the processing efficiency can be improved when the surface linear velocity of the processing roller remains unchanged.

[0008] Preferably, the traction power assembly includes a traction and compacting roller for cooperating with the material to be compacted and a traction motor for driving the traction and compacting roller to rotate, and the rotation speed of the traction motor is adjustable.

[0009] By adopting the above technical solution, the traction motor drives the traction pressing roller to rotate, and the material conveying speed can be controlled by adjusting the speed of the traction motor.

[0010] Preferably, the traction power assembly further includes a traction auxiliary roller and a traction pressure source for applying opposite forces to the traction auxiliary roller and the traction pressure roller.

[0011] By adopting the above technical solution, the traction pressure source provides a force, so that the traction auxiliary roller and the traction pressing roller move towards each other to press the material.

[0012] 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.

[0013] 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.

[0014] 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 away from the relay clamping roller.

[0015] 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 tensioning the material, which serves as redundancy when the speeds of the front and rear traction power components conveying materials are inconsistent.

[0016] Preferably, the relay tensioning assembly further comprises a 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.

[0017] By adopting the above technical solution, at least two relay tensioning movable rollers are arranged to cooperate with the relay tensioning fixed roller, so that the relay tensioning assembly has greater material storage redundancy, and the tensioning power source only needs a small range of movement to achieve large-stroke tensioning.

[0018] Preferably, the traction power assembly includes a traction power movable roller and a traction power source for driving the traction power movable roller to move toward or away from the bottom roller.

[0019] By adopting the above technical solution, the traction power source is used to directly drive the traction power active roller to move, instead of adjusting the material conveying speed by controlling the rotation speed of the traction pressure roller.

[0020] Preferably, a traction power track is provided on the frame, and the traction power movable roller is installed on the traction power track and is driven by the traction power source to slide along the traction power track.

[0021] By adopting the above technical solution, another solution for adjusting the conveying speed of materials is realized.

[0022] Preferably, the frame is provided with a traction power swing arm with one end rotatably connected to the frame, the traction power movable roller is installed on the traction power swing arm, and the traction power source drives the traction power swing arm to swing.

[0023] By adopting the above technical solution, another solution for adjusting the conveying speed of materials is realized.

[0024] In a second aspect, the present application provides a device for cutting, printing or embossing, which adopts the following technical solution:

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

[0026] By adopting the above technical solution, the efficiency of equipment in processing materials can be improved.

[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 component is greater than the linear speed of the processing roller surface, and the processing roller processes the material in multiple stages, so the processing efficiency can be improved while the linear speed of the processing roller surface 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 tensioning material, serving as redundancy when the speeds of the front and rear traction power components conveying materials are inconsistent.

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The embodiments of the present application disclose a multi-unit device for cutting, printing or stamping and a device using the device. The terms "upper", "lower", "left" and "right" used in the embodiments are used to describe the relative directions of the positional relationship, and are not intended to limit the positional relationship.

[0038] Embodiment 1:

[0039] like Figure 1 As shown, the multi-unit device for cutting, printing or stamping includes a frame 1 and three sets of processing traction mechanisms 2 located on the frame 1, each set of processing traction mechanisms 2 includes a processing roller 3, a bottom roller 4 matched with the processing roller 3, a traction power assembly 5 for variable speed traction of materials, and a relay tension assembly 6 for tensioning materials. Each processing roller 3 is provided with a processing area and a non-processing area. For example, when used for cutting operations, the area on the surface of the processing roller 3 with a magnetic blade skin is the processing area, and the area without a magnetic blade skin is the non-processing area.

[0040] like Figure 1 and Figure 2 As shown, the traction power assembly 5 includes a traction pressing roller 7 and a traction auxiliary roller 8 for pressing the material, a traction motor for driving the traction pressing roller 7 to rotate, and a traction cylinder 9 for applying opposite forces to the traction auxiliary roller 8 and the traction pressing roller 7 (the traction cylinder 9 can be replaced by other components for applying pressure). The traction motor is a servo motor or other motors that can accurately control and adjust the speed. A traction direction-changing roller 10 for adjusting the direction of the material is installed at the lower left position of the traction pressing roller 7 on the frame 1. Traction swing arms 11 are installed at both ends of the traction auxiliary roller 8. One end of the traction swing arm 11 is rotatably connected to the frame 1, the middle part of the traction swing arm 11 is rotatably connected to the traction auxiliary roller 8, the other end of the traction swing arm 11 is rotatably connected to one end of the traction cylinder 9, and the other end of the traction cylinder 9 is rotatably connected to the frame 1. The traction cylinder 9 drives the traction swing arm 11 to swing, so that the traction auxiliary roller 8 is pressed on the traction clamping roller 7 to clamp the material, and then the traction motor drives the traction clamping roller 7 to rotate, so that the material is transported forward at the same speed as the outer ring linear speed of the traction clamping roller 7.

[0041] like Figure 1 and Figure 3 As shown, the relay tensioning assembly 6 includes a relay tensioning rail 12 installed on the frame 1 in the vertical direction, two relay tensioning active rollers 14 fixed on the slider 13 of the relay tensioning rail 12, a relay tensioning fixed roller 15 installed on the frame 1 and located above the relay tensioning rail 12, and a tensioning power source 16 connecting the slider 13 and the lower end of the relay tensioning rail 12. The tensioning power source 16 can be a spring, an elastic belt, or a cylinder or motor screw structure that cooperates with real-time adjustment of the tensioning.

[0042] The material flow is as follows: the material passes through three sets of processing traction mechanisms 2 from left to right in turn. When entering each set of processing traction mechanism 2, it first passes through the position between the bottom roller 4 and the processing roller 3, then passes through the traction changing roller 10 downward and then enters the position between the traction clamping roller 7 and the traction auxiliary roller 8 upward; then passes through the relay tensioning active roller 14 on the left downward, then bypasses the relay tensioning fixed roller 15 upward, and then bypasses the relay tensioning active roller 14 on the right downward, and finally enters the next workstation.

[0043] Specific working process:

[0044] All processing motors drive the processing rollers 3 to rotate at a fixed speed. When the material passes through the position between the processing rollers 3 and the bottom rollers 4 of the first set of processing traction mechanisms 2, and the processing area of ​​the processing rollers 3 cooperates with the bottom rollers 4, the traction motor drives the traction pressing rollers 7 to rotate at a surface linear velocity that is the same as the surface linear velocity of the processing rollers 3. At this time, the processing rollers 3 process the material to form a processing section. When the processing rollers 3 rotate to the position where the non-processing area cooperates with the bottom rollers 4, the first section of the material surface processing has been completed. The traction motor speed is increased, so that the processing rollers 3 rotate to the next processing area and the bottom rollers 4 cooperate. The traction power assembly 5 drives the material to be transported forward quickly, so that the material surface forms an unprocessed section twice the length of the processing section.

[0045] The material is transported to the second processing traction mechanism 2. When the processing roller 3 of the second processing traction mechanism 2 rotates to the position where the non-processing area and the bottom roller 4 match, the traction motor adjusts the speed to drive the traction and pressing roller 7 to rotate, so that when the processing roller 3 rotates to the position where the processing area and the bottom roller 4 match, the unprocessed section of the material reaches the position between the processing roller 3 and the bottom roller 4. Then the speed of the traction motor is changed so that the traction motor drives the traction and pressing roller 7 to rotate at the same surface linear velocity as the surface linear velocity of the processing roller 3. At this time, half of the remaining unprocessed section is processed to form a processed section.

[0046] The material is transported to the third processing traction mechanism 2. When the processing roller 3 of the third processing traction mechanism 2 rotates to the position where the non-processing area and the bottom roller 4 match, the traction motor adjusts the speed to drive the traction and pressing roller 7 to rotate, so that when the processing roller 3 rotates to the position where the processing area and the bottom roller 4 match, the unprocessed section of the material reaches the position between the processing roller 3 and the bottom roller 4. Then the speed of the traction motor is changed so that the traction motor drives the traction and pressing roller 7 to rotate at the same surface linear velocity as the surface linear velocity of the processing roller 3, completing the processing of the last unprocessed section.
