Description

An automatic correction mechanism for a slitting machine Technical Field

[0001] This utility model relates to the field of correction mechanism technology, specifically an automatic correction mechanism for a slitting machine. Background Technology

[0002] A slitting machine is a key piece of equipment in the paper industry for cutting and sorting various types of paper rolls (such as cable paper, capacitor paper, and cigarette paper). It consists of multiple sets of cutting devices, including upper and lower blades, which can cut multiple narrow, disc-shaped paper rolls at once.

[0003] Application number CN202223369757.7 discloses a web-aligning device for cutting and rewinding composite films, belonging to the field of composite film production technology, including structures such as composite film web-aligning rollers. This web-aligning device for cutting and rewinding composite films is easy to adjust and facilitates subsequent rewinding of the composite film. In practical use, this application has two stops to limit the composite film, thereby preventing it from deviating. However, this also makes it easy for the edges of the composite film to fold, affecting the rewinding effect. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] An automatic correction mechanism for a slitting machine includes an adjustment mechanism, a limiting mechanism, and a distance control mechanism. The adjustment mechanism includes a motor, a threaded rod connected to the output shaft of the motor, two sleeves connected to the threaded rod, a roller movably mounted on the bottom of the sleeve, a motor connected between the sleeve and the roller, a frame mounted on the outside of the sleeve, and a camera mounted inside the frame. The two motors and the two cameras are connected in series. The limiting mechanism includes a canopy movably fitted onto the top of the threaded rod, two guide rods extending laterally through the canopy, and multiple guide sleeves slidably fitted onto the outside of the guide rods and connected to the sleeves. The distance control mechanism includes two lifting plates located at both ends of the canopy and slidably connected between the two guide rods, and a hydraulic cylinder connected between the motor and the lifting plates.

[0007] By employing the above technical solution, two cameras work together to capture the position of the composite membrane. The captured image is transmitted to an external PLC, which controls the rotation of the motor output shaft. Then, the threaded rod affects the translation of the guide sleeve, which is limited by the guide sleeve. The rollers then follow the translation. When the two rollers approach the two sides of the composite membrane, the external PLC controls the retraction of the movable end of the hydraulic cylinder. The lifting plate then lowers the canopy, which in turn lowers the two rollers and fits them against the top of the composite membrane. Based on the offset of the composite membrane, the external PLC controls the rotation direction of the motor, and the two rollers work together to correct the position of the composite membrane. This method does not affect the folding of the composite membrane edges.

[0008] In a preferred embodiment, the present invention can be further configured such that the external thread of the threaded rod is set in two segments with opposite directions of rotation.

[0009] In a preferred embodiment, the present invention can be further configured as follows: multiple guide sleeves are arranged in pairs, forming two groups, with the two guide sleeves in each group located on both sides of the two rod sleeves respectively.

[0010] In a preferred embodiment, this invention can be further configured as follows: two hydraulic cylinders are connected in series, and the motor, camera, and hydraulic cylinders are all electrically connected to an external PLC.

[0011] In a preferred embodiment, the present invention can be further configured such that a take-up roller is provided between the two lifting plates, and both rollers are suspended above the take-up roller.

[0012] In a preferred embodiment, the present invention can be further configured such that: a base plate is installed at the bottom of the take-up roller, and the bottom end of the hydraulic cylinder is fixedly connected to the top of the base plate.

[0013] In a preferred embodiment, the present invention can be further configured such that: two vertical rods are slidably inserted into the bottom of the lifting plate, and the bottom end of the vertical rods is fixedly connected to the top of the base plate.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] In this invention, two cameras work together to capture the position of the composite film. The captured image is transmitted to an external PLC, which controls the motor output shaft to rotate. Then, the threaded rod affects the translation of the guide sleeve, which is limited by the guide sleeve. The rollers then follow the translation. When the two rollers approach the two sides of the composite film, the external PLC controls the movable end of the hydraulic cylinder to retract. Then, the lifting plate lowers with the canopy, and the canopy lowers with the two rollers to fit against the top of the composite film. Then, according to the offset of the composite film, the external PLC controls the direction of the motor rotation, and the two rollers work together to correct the position of the composite film. This method does not affect the folding of the composite film edges. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of an automatic correction mechanism for a slitting machine.

[0030] Example 1:

[0031] As shown in Figures 1-4, the present invention provides an automatic correction mechanism for a slitting machine, comprising an adjustment mechanism 100, a limiting mechanism 200, and a distance control mechanism 300. The adjustment mechanism 100 includes a motor 110, a threaded rod 120 connected to the output shaft of the motor 110, two rod sleeves 130 connected to the threaded rod 120, a roller 140 movably mounted at the bottom of the rod sleeve 130, a motor 150 connected between the rod sleeve 130 and the roller 140, a frame 160 mounted on the outside of the rod sleeve 130, and a camera 170 mounted inside the frame 160. The two motors 150 are connected in series, and the two cameras 170 are connected in series.

[0032] The limiting mechanism 200 includes a canopy 210 movably sleeved on the top of the threaded rod 120, two guide rods 220 transversely penetrating the canopy 210, and a plurality of guide sleeves 230 slidably sleeved on the outside of the guide rods 220 and connected to the rod sleeve 130.

[0033] The distance control mechanism 300 includes two lifting plates 310 located at both ends of the ceiling 210 and slidably connected between two guide rods 220, and a hydraulic cylinder 320 connected between the motor 110 and the lifting plates 310.

[0034] Furthermore, the external thread of the threaded rod 120 is set in two segments with opposite directions of rotation. This structural design ensures that the two rod sleeves 130 can widen or narrow the gap to fully adapt to composite films of different sizes.

[0035] Furthermore, multiple guide sleeves 230 are arranged in pairs, forming two groups. In each group, two guide sleeves 230 are located on both sides of two rod sleeves 130. The layout design of the guide sleeves 230 can stabilize the guide rod sleeves 130, making their movement more stable.

[0036] Furthermore, the two hydraulic cylinders 320 are connected in series, and the motor 150, camera 170, and hydraulic cylinder 320 are all electrically connected to an external PLC. With this structural design, the device will be more intelligent and convenient.

[0037] Example 2:

[0038] As shown in Figure 1, based on Embodiment 1, a take-up roller 400 is provided between the two lifting plates 310, and two rollers 140 are suspended above the take-up roller 400. The position of the take-up roller 400 ensures that the rollers 140 can rub against the composite film, providing conditions for adjusting the position of the composite film.

[0039] Furthermore, a base plate 500 is installed at the bottom of the take-up roller 400, and the bottom end of the hydraulic cylinder 320 is fixedly connected to the top of the base plate 500. The base plate 500 provides conditions for stabilizing the take-up roller 400.

[0040] Example 3:

[0041] As shown in Figure 1, in the above embodiment, two vertical rods 600 are slidably inserted into the bottom of the lifting plate 310. The bottom end of the vertical rods 600 is fixedly connected to the top of the base plate 500. The vertical rods 600 serve to guide the lifting plate 310.

[0042] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the composite film is wound up by the winding roller 400. During this process, two cameras 170 cooperate to capture the position of the composite film. The captured images are transmitted to an external PLC. Then, the external PLC controls the output shaft of the motor 110 to rotate. Then, the threaded rod 120 affects the translation of the rod sleeve 130, which is limited by the guide sleeve 230. Then, the rollers 140 follow the translation. When the two rollers 140 approach the two sides of the composite film, the external PLC controls the movable end of the hydraulic cylinder 320 to retract. Then, the lifting plate 310 lowers the top canopy 210. The top canopy 210 indirectly lowers the two rollers 140 and fits against the top of the composite film. Then, according to the offset of the composite film, the external PLC controls the rotation direction of the motor 150. Then, the two rollers 140 cooperate to complete the correction of the position of the composite film.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
