Description

Technical Field

[0001] The utility model belongs to the technical field of plastic film printing, in particular to a deviation-correcting device of a printing press for processing plastic films. Background Art

[0002] A plastic film printing machine is a machine that prints single-color or multi-color patterns onto a plastic film. The rolled plastic film is unwound by an unwinder and then conveyed to an imprinting device to be imprinted with a pattern or color. The pattern is then quickly dried by a drying device or an air-drying device, and then the dried PVC film is wound up by a winder. When the existing printing machine is in use, the printed film is prone to deviation when it is rolled up to the winder. Therefore, a deviation correction device for a printing machine for plastic film processing is urgently needed to solve the problem.

[0003] However, the existing plastic film processing printing machine correction device is difficult to correct the films of different widths during use. Due to the different spans, position deviation is more likely to occur during the transmission process, making correction more difficult, time-consuming and labor-intensive. As a result, workers need to spend a lot of time adjusting the equipment, which greatly prolongs the processing time. Utility Model Content

[0004] The purpose of the utility model is to provide a deviation correction device for a printing press for processing plastic film. By setting a deviation correction mechanism, the problem that the existing deviation correction device for a printing press for processing plastic film is difficult to correct the films of different widths during use is solved. Due to the different spans, position deviation is more likely to occur during the transmission process, which increases the difficulty of deviation correction and is time-consuming and labor-intensive. As a result, the staff needs to spend a lot of time on adjusting the equipment, thereby greatly extending the processing time.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a deviation-correcting device for a printing press used for processing plastic films, comprising a workbench on which a deviation-correcting mechanism and a tension-adjusting mechanism are arranged;

[0007] The correction mechanism includes a correction component and a limiting component. The correction component includes two brackets 1 fixedly connected to the top of the workbench. A fixed shaft 1 is fixedly connected between the two brackets 1, and a roller 1 is rotatably connected to the outer wall of the fixed shaft 1.

[0008] Furthermore, the top of the workbench is fixedly connected to a bracket 2, and a bidirectional threaded rod is rotatably connected to the inner wall of the bracket 2. The left side of the bidirectional threaded rod rotates through the outer wall of the bracket 2 and extends to the outside.

[0009] Furthermore, the limiting assembly includes a bracket three fixedly connected to the top of the workbench, the top of the bracket three is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the bidirectional threaded rod through a coupling.

[0010] Furthermore, two sliders 1 are slidably connected to the inner wall of the bracket 2, and the two sliders 1 are mirror images of each other. The left and right sides of the bidirectional threaded rod pass through the two sliders 1 respectively. A platform is fixedly connected to the inner wall of the bracket 2, and the top of the platform is slidably connected to a limiting plate. The inner walls of the two limiting plates are fixedly connected to the two sliders 1 respectively.

[0011] Furthermore, the tension adjustment mechanism includes a positioning component and an adjustment component. The positioning component includes two brackets four fixedly connected to the top of the workbench. A fixed shaft two is fixedly connected between the two brackets four. A roller two is rotatably connected to the outer wall of the fixed shaft two.

[0012] Furthermore, two brackets five are fixedly connected to the top of the workbench, two sliding grooves are provided on the inner walls of the two brackets five, sliders two are slidably connected to the inner walls of the two brackets five, two limit blocks are fixedly connected to the outer walls of the two sliders two, and several limit blocks slide in several sliding grooves respectively.

[0013] Furthermore, the adjustment assembly includes a fixed shaft three fixedly connected between two brackets five, and a roller three is rotatably connected to the outer wall of the fixed shaft three.

[0014] Furthermore, the bottoms of the two sliders are fixedly connected to telescopic rods, the bottoms of the two telescopic rods are fixedly connected to the workbench, the outer walls of the two telescopic rods are sleeved with springs, the tops of the two springs are fixedly connected to two slide grooves respectively, the bottoms of the two springs are fixedly connected to the workbench, and the top of the workbench is fixedly connected to a winding module.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up a deviation correction mechanism, the motor can be started to rotate its output shaft. When the width of the film is small, the output shaft of the motor is rotated forward. When the output shaft of the motor rotates forward, it will drive the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it will drive the two sliders one to approach each other under the action of the bracket two. When the two sliders one are close to each other, they will drive the two limit plates to approach each other, thereby reducing the sliding range of the film on the top of the platform, thereby achieving deviation correction. Similarly, when the width of the film is large, the output shaft of the motor can be reversed to make the two limit plates move away from each other, so that when facing the processing of films with different widths, the width of the deviation correction device can be adjusted in time, saving time and effort, greatly reducing processing time, improving product quality, and reducing production costs.

[0017] 2. By setting up a tension adjustment mechanism, the film can pass through the bottom of roller two, then bypass the top of roller three, and finally be rolled into the winding module. When the tension of the film is too large, pressure will be applied to roller three. When roller three is under pressure, it will drive slider two to slide on the inner wall of bracket five through fixed shaft three. When slider two slides on the inner wall of bracket five, it will compress the spring, causing it to undergo elastic deformation and generate elastic force, thereby offsetting the excessive tension. When the tension decreases, the spring will rebound under the action of the elastic force, thereby realizing tension adjustment, so that the tension of the film can be adjusted in real time, avoiding changes in film width, and even frequent film breakage and wear of equipment, greatly improving production efficiency and product quality.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A platform 224 is fixedly connected to the inner wall of the bracket two 214, and the top of the platform 224 is slidably connected to a limit plate 225.

[0029] The tension adjustment mechanism 3 includes a positioning component 31 and an adjustment component 32. The positioning component 31 includes two brackets 4 311 fixedly connected to the top of the workbench 1. A fixed shaft 2 312 is fixedly connected between the two brackets 4 311. A roller 2 313 is rotatably connected to the outer wall of the fixed shaft 2 312. Two brackets 5 314 are fixedly connected to the top of the workbench 1. Two slide grooves 315 are provided on the inner walls of the two brackets 5 314. Slide blocks 2 316 are slidably connected to the inner walls of the two brackets 5 314. Two limit blocks 317 are fixedly connected to the outer walls of the two slide blocks 2 316. Several limit blocks 317 slide in several slide grooves 315 respectively. The adjustment component 32 includes two brackets 5 314 fixedly connected to the top of the workbench 1.

[0030] A specific application of this embodiment is as follows: when in use, the device is first installed to the corresponding position, and the processed film passes through the top of roller 1 213 and then passes through the top of platform 224. When passing the top of platform 224, the motor 222 can be started to rotate its output shaft. When the width of the film is small, the output shaft of motor 222 is rotated forward.

Similarly, when the width of the film is large, the output shaft of motor 222 can be reversed to make the two limit plates 225 move away from each other, so that when facing the processing of films with different widths, the deviation correction device can be adjusted in time. When the film passes through the platform 224, it can pass through the bottom of the second roller 313, then around the top of the third roller 322, and finally be rolled into the winding module 325. When the tension of the film is too great, pressure will be applied to the third roller 322. When the third roller 322 receives pressure, it will drive the second slider 316 to slide on the inner wall of the fifth bracket 314 through the fixed shaft 321. When the second slider 316 slides on the inner wall of the fifth bracket 314, it will compress the spring 324, causing it to undergo elastic deformation and generate elastic force, thereby offsetting the excessive tension. When the tension decreases, the spring 324 will rebound under the action of the elastic force, thereby realizing the adjustment of the tension, so that the tension of the film can be adjusted in real time, avoiding changes in the film width, or even frequent film breakage and wear of the equipment, thereby greatly improving production efficiency and improving product quality.
