Description

Technical Field

[0001] This application relates to the field of die-cutting machine technology, and in particular to an adjustable bottom roller for a die-cutting machine. Background Technology

[0002] A die-cutting machine is a mechanical device that uses a pre-set mold to cut and shape flexible materials such as paper, film, rubber, and metal foil. Its core function is to achieve precise cutting, creasing, punching, and other processing of materials. It is widely used in industries such as packaging, printing, electronics, and building materials.

[0003] The related technology discloses a paper die-cutting machine, including a frame, an upper roller and a bottom roller rotatably mounted on the frame, and roller shoulders arranged at both ends of the upper roller and the bottom roller. An adjusting component is arranged on the frame to adjust the distance between the upper roller shoulder of the bottom roller and the upper roller shoulder of the upper roller, so as to be suitable for die-cutting of paper of different thicknesses. The adjusting component adopts a lead screw and a threaded block, and the threaded block is connected to the roller shoulder on the bottom roller.

[0004] The adjustment of the shoulder position on the bottom roller is achieved manually by a worker operating a lead screw. However, since the two adjustment components need to be operated by different workers, it is difficult to maintain precise synchronization, which can easily lead to jamming and inconvenience in operation. Moreover, because the paper is relatively thin, the adjustment amount required for the shoulder position is usually small, and the precision of the lead screw and threaded block adjustment method is often low, which has obvious shortcomings. Summary of the Invention

[0005] To improve the problems of inconvenient and inaccurate adjustment of the bottom roller, this application provides an adjustable bottom roller for a die-cutting machine.

[0006] This application provides an adjustable bottom roller for a die-cutting machine, which adopts the following technical solution: An adjustable bottom roller for a die-cutting machine includes a frame and a bottom roller rotatably mounted on the frame. A deflecting gear disc is coaxially rotatably mounted on the bottom roller near both ends. A roller shoulder is eccentrically mounted on the deflecting gear disc. A transmission rod parallel to the bottom roller is rotatably mounted on the frame. Micro-gears corresponding to and meshing with the two deflecting gear discs are arranged on the transmission rod. An adjusting seat is also rotatably mounted on the frame. A drive gear set that drives the transmission rod and the adjusting seat is arranged on the frame.

[0007] By adopting the above technical solution, the worker manually rotates the adjustment seat, which drives the transmission rod to rotate through the drive gear set. The transmission rod drives the deflection gear disk to rotate through the micro gear, and the deflection gear disk drives the roller shoulder to rotate. Since the roller shoulder and the deflection gear disk are eccentrically set, the distance between the roller shoulder of the upper roller and the bottom roller can be adjusted during the rotation. The circumferential rotation of the roller shoulder is achieved through the gear, which not only facilitates adjustment but also has high adjustment accuracy.

[0008] Optionally, a transmission sleeve is rotatably sleeved on the transmission rod, one micro gear is fixedly sleeved on the transmission, and another is fixedly sleeved on the transmission rod. A driven gear one is fixedly sleeved on the transmission rod, and a driven gear two is also fixedly sleeved on the transmission sleeve. The frame is provided with a fixed locking disc. The adjusting seat includes an inner sleeve that slides and rotates through the fixed locking disc. An inner rod slides and rotates through the inner sleeve. The inner sleeve extends to the outside of the fixed locking disc and an outer sleeve is provided on its outer side wall. The inner rod extends to the outside of the inner sleeve and an outer rod sleeve is provided on its outer side wall. The fixed locking disc has a plurality of first insertion holes circumferentially. The outer sleeve has a first pin that engages with the first insertion holes. The outer sleeve has a plurality of second insertion holes circumferentially. The outer rod sleeve has a second pin that engages with the second insertion holes. The drive gear set includes a first driving gear fixedly sleeved on the inner sleeve and a second driving gear fixedly sleeved on the inner through rod. The first driving gear is driven by the first driven gear, and the second driving gear is driven by the second driven gear.

[0009] Optionally, at least one transmission gear set is arranged on the frame, each transmission gear set including two transmission gears that are independently rotatably connected to the frame. One transmission gear in each transmission gear set is driven between the first driving gear and the first driven gear, and the other transmission gear is driven between the second driving gear and the second driven gear.

[0010] Optionally, the outer sleeve is configured as an outer shell that slides outside the inner sleeve and an outer core that slides outside the inner sleeve. The first pin is located on the outer shell, and the second insertion hole is located on the outer core. The outer rod sleeve includes an outer end shell that slides outside the inner rod and an outer end core that slides outside the inner rod. The second pin is located on the outer end shell. A fastening bolt one is threaded onto the outer core and abuts against the outer circumferential wall of the inner sleeve. A fastening bolt two is threaded onto the outer core and abuts against the outer circumferential wall of the inner rod. The outer shell and the outer core, and the outer end shell and the outer core are all connected by guide rods. The fixing lock plate is detachably connected to the frame.

[0011] By adopting the above technical solution, workers can manually disassemble and replace structures such as the outer shell, outer core, outer end shell, outer end core, and fixing lock plate, thereby adjusting the minimum adjustment base of the adjustment seat and achieving more precise spacing control.

[0012] Optionally, compression springs are provided between the outer shell and the outer core, and between the outer end shell and the outer end core.

[0013] Optionally, the outer wall of the inner through rod is provided with a contact-isolating groove in the circumferential direction at the position relative to the inner sleeve.

[0014] Optionally, anti-slip textures are arranged on the outer side walls of both the outer shell and the outer end shell.

[0015] In summary, this application includes at least one of the following beneficial technical effects: The worker manually rotates the adjusting seat, which drives the transmission rod to rotate through the drive gear set. The transmission rod drives the deflection gear disk to rotate through the micro gear, and the deflection gear disk drives the roller shoulder to rotate. Because the roller shoulder and the deflection gear disk are eccentrically set, the distance between the roller shoulder of the upper roller and the bottom roller can be adjusted during the rotation. The circumferential rotation of the roller shoulder is achieved through the gear, which is not only convenient to adjust but also has high adjustment accuracy. Workers can manually disassemble and replace the outer shell, outer core, outer end shell, outer end core, and fixing lock plate, thereby adjusting the minimum adjustment base of the adjustment seat and achieving more precise spacing control.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses an adjustable bottom roller for a die-cutting machine.

[0022] Reference Figure 1The adjustable bottom roller 2 of the die-cutting machine includes a hollow frame 1 and a bottom roller 2 that is rotatably mounted on the frame 1. A deflection gear disk 3 is coaxially rotatably mounted on the bottom roller 2 near both ends, and a roller shoulder 4 is eccentrically fixed on the deflection gear disk.

[0023] Reference Figure 1 and Figure 2 A transmission rod 5 parallel to the bottom roller 2 is mounted on the frame 1. A transmission sleeve 9 is coaxially mounted on the transmission rod 5. A micro gear 6 is integrally formed on the outer circumferential wall of the transmission sleeve 9. A micro gear 6 is also fixedly mounted on the transmission rod 5. The two micro gears 6 correspond one-to-one with the two deflection gear disks 3 and mesh with each other.

[0024] A driven gear 10 is fixedly sleeved on the outer circumferential wall of one end of the transmission rod 5 inside the frame 1, and a driven gear 11 is integrally formed on the outer circumferential wall of one end of the transmission sleeve 9 inside the frame 1.

[0025] Reference Figure 2 and Figure 3 An adjusting seat 7 is rotatably arranged on the frame 1, and a drive gear set 8 that drives the transmission rod 5 and the adjusting seat 7 is also arranged on the frame 1.

[0026] Reference Figure 2 and Figure 3 A fixed locking disc 12 is bolted to the frame 1. The adjusting seat 7 includes an inner sleeve 71 that slides and rotates coaxially within the fixed locking disc 12. An inner through rod 72 slides and rotates coaxially within the inner sleeve 71. A contact-isolating groove 721 is circumferentially opened on the outer wall of the inner through rod 72 relative to the position of the inner sleeve 71.

[0027] The drive gear set 8 includes a first drive gear 81 fixedly sleeved on the inner sleeve 71 and a second drive gear 82 fixedly sleeved on the inner through rod 72. The first drive gear 81 is driven by the first driven gear 10, and the second drive gear 82 is driven by the second driven gear 11.

[0028] The inner sleeve 71 extends to the outside of the fixed locking disc 12 and an outer sleeve is arranged on the outer side wall; the inner through rod 72 extends to the outside of the inner sleeve 71 and an outer rod is arranged on the outer side wall.

[0029] Reference Figure 2 and Figure 3 The outer sleeve is divided into an outer shell 731 that is slidably sleeved outside the inner sleeve 71 and an outer core 732 that is slidably sleeved outside the inner sleeve 71. The outer core 732 is threaded with a fastening bolt 77 for pressing against the outer circumferential wall of the inner sleeve 71. The outer shell 731 and the outer core 732 are connected by a guide rod 14. A compression spring 15 is also provided between the outer shell 731 and the outer core 732.

[0030] Reference Figure 2 and Figure 3 The outer rod sleeve 74 is divided into an outer end shell 741 that is slidably sleeved outside the inner through rod 72 and an outer end core 742 that is slidably sleeved outside the inner through rod 72. The outer end core 742 is threaded with a fastening bolt 78 for pressing against the outer circumferential wall of the inner through rod 72. The outer end shell 741 and the outer end core 742 are also connected by a guide rod 14. A compression spring 15 is also provided between the outer end shell 741 and the outer end core 742.

[0031] Reference Figure 2 and Figure 3 The fixed locking disc 12 has multiple first insertion holes 121 circumferentially opened, and the outer shell 731 has a first pin 75 that is interference-fitted with it, and the first pin 75 is inserted into the first insertion hole 121.

[0032] The outer core 732 has multiple second insertion holes 7321 circumferentially opened, and the outer end shell 741 has a second pin 76 that is interference-fitted with the second insertion hole 7321.

[0033] Reference Figure 2 and Figure 3 At least one transmission wheel set is arranged inside the frame 1. Each transmission wheel set includes two transmission gears 13. The two transmission gears 13 in the same set are independently connected to the frame 1.

[0034] One transmission gear 13 of each transmission gear set is driven between the driving gear 81 and the driven gear 10, and the other transmission gear 13 is driven between the driving gear 82 and the driven gear 11.

[0035] Reference Figure 2 and Figure 3 Since the bottom roller 2 of this application is installed inside the die-cutting machine, and the die-cutting machine has limited space and a compact structure, it is actually designed with three working conditions.

[0036] Reference Figure 2 and Figure 3In the first working condition: the worker pulls the outer sleeve 73, causing the first pin 75 to disengage from the first insertion hole 121, while the second pin 76 remains inserted into the second insertion hole 7321. At this time, the outer sleeve 73 is rotated, causing the outer rod sleeve 74 to rotate. Meanwhile, the inner sleeve 71 drives the first drive gear 81 and the second drive gear 82 on the inner rod 72 to rotate synchronously in the circumferential direction. Under the action of multiple sets of transmission gears 13, the driven gear 10 drives the corresponding micro gear 6 to rotate through the transmission rod 5, while the driven gear 2 11 drives the corresponding micro gear 6 to rotate through the transmission sleeve 9. The two micro gears 6 rotate synchronously and in the same direction, driving their respective deflection gear disks 3 to rotate. The deflection gear disks 3 drive the roller shoulders 4 to rotate, thereby adjusting the distance between the upper roller and the upper roller shoulders 4 of the bottom roller 2. The key point of this working condition is that the roller shoulders 4 at both ends of the bottom roller 2 are simultaneously subjected to force and move.

[0037] Reference Figure 2 and Figure 3 In the second working condition, the worker moves the outer sleeve core 732 towards the frame 1, and the outer rod sleeve 74 remains stationary, causing the second pin 76 to disengage from the second insertion hole 7321. Then, the worker rotates the outer rod sleeve 74, which drives the second drive gear 82 to rotate through the inner through rod 72. At this time, the first drive gear 81 remains stationary, and the second drive gear 82 drives the second driven gear 11 to rotate through the corresponding transmission gear 13. The second driven gear 11 drives the corresponding micro gear 6 to rotate through the transmission sleeve 9. In other words, at this time, only the roller shoulder 4 on the bottom roller 2 near the adjusting seat 7 can be adjusted.

[0038] Reference Figure 2 and Figure 3 In the third working condition, the worker pulls the outer sleeve 73, which in turn pulls the outer rod sleeve 74, causing the first pin 75 to disengage from the first insertion hole 121 and the second pin 76 to disengage from the second insertion hole 7321. After that, the outer sleeve 73 is rotated while the outer rod sleeve 74 remains stationary. The outer sleeve 73 drives the first drive gear 81 to rotate through the inner sleeve 71. At this time, the second drive gear 82 remains stationary. The first drive gear 81 drives the driven gear 10 to rotate through the corresponding transmission gear 13. The driven gear 10 drives the corresponding micro gear 6 to rotate through the transmission rod 5. In other words, at this time, only the roller shoulder 4 on the side of the bottom roller 2 away from the adjusting seat 7 can be adjusted.

[0039] The above three working conditions are based on the actual situation of the customer, and take into account factors such as the compact space inside the die-cutting machine, so that workers can make appropriate structural modifications to meet the actual usage needs.

[0040] Reference Figure 3 To facilitate turning, anti-slip textures (not shown in the figure) are arranged on the outer circumferential outer walls of the outer shell 731 and the outer end shell 741 to increase friction with the worker's hands and thus avoid the possibility of slipping.

[0041] The implementation principle of the adjustable bottom roller 2 of the die-cutting machine in this application embodiment is as follows: The first working condition: The worker pulls the outer sleeve 73, causing the first pin 75 to disengage from the first insertion hole 121, while the second pin 76 remains inserted into the second insertion hole 7321. At this time, the outer sleeve 73 is rotated, causing the outer rod sleeve 74 to rotate. Meanwhile, the inner sleeve 71 drives the first drive gear 81 and the second drive gear 82 on the inner rod 72 to rotate synchronously in the circumferential direction. Under the action of multiple sets of transmission gears 13, the driven gear 10 drives the corresponding micro gear 6 to rotate through the transmission rod 5, while the driven gear 2 11 drives the corresponding micro gear 6 to rotate through the transmission sleeve 9. The two micro gears 6 rotate synchronously and in the same direction, driving their respective deflection gear disks 3 to rotate. The deflection gear disks 3 drive the roller shoulders 4 to rotate, thereby adjusting the distance between the upper roller and the roller shoulders 4 of the bottom roller 2. The key point of this working condition is that the roller shoulders 4 at both ends of the bottom roller 2 are simultaneously subjected to force and move.

[0042] In the second working condition, the worker moves the outer sleeve core 732 towards the frame 1, and the outer rod sleeve 74 remains stationary, causing the second pin 76 to disengage from the second insertion hole 7321. Then, the worker rotates the outer rod sleeve 74, which drives the second drive gear 82 to rotate through the inner through rod 72. At this time, the first drive gear 81 remains stationary, and the second drive gear 82 drives the second driven gear 11 to rotate through the corresponding transmission gear 13. The second driven gear 11 drives the corresponding micro gear 6 to rotate through the transmission sleeve 9. In other words, at this time, only the roller shoulder 4 on the bottom roller 2 near the adjusting seat 7 can be adjusted.

[0043] In the third working condition, the worker pulls the outer sleeve 73, which in turn pulls the outer rod sleeve 74, causing the first pin 75 to disengage from the first insertion hole 121 and the second pin 76 to disengage from the second insertion hole 7321. After that, the outer sleeve 73 is rotated while the outer rod sleeve 74 remains stationary. The outer sleeve 73 drives the first drive gear 81 to rotate through the inner sleeve 71. At this time, the second drive gear 82 remains stationary. The first drive gear 81 drives the driven gear 10 to rotate through the corresponding transmission gear 13. The driven gear 10 drives the corresponding micro gear 6 to rotate through the transmission rod 5. In other words, at this time, only the roller shoulder 4 on the side of the bottom roller 2 away from the adjusting seat 7 can be adjusted.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
