Description

Technical Field

[0001] This utility model belongs to the field of film slitting technology, specifically relating to a film slitting machine for the production of polyvinyl chloride color film. Background Technology

[0002] Polyvinyl chloride (PVC) colored film is widely used in construction, packaging, advertising, home furnishing, and many other fields due to its excellent flexibility, corrosion resistance, and decorative properties. With the continuous development of various industries, the demand for PVC colored film is increasing, and the requirements for its quality and specifications are also becoming more stringent. In the production process, film slitting is a crucial step that directly affects the final quality and performance of the colored film.

[0003] In traditional PVC color film production, the cutting devices of film slitting machines often lack flexibility. Many slitting machines have fixed cutting blade positions, allowing them to slit color films of specific widths only. When producing color films of different widths, different cutting equipment or complex adjustments to the existing equipment are required, which not only increases production costs and time but also reduces production efficiency. Moreover, for color films of different thicknesses, traditional slitting machines struggle to flexibly adjust the cutting blade height according to actual conditions, leading to unstable cutting results and problems such as incomplete cutting or over-cutting. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a film slitting machine for the production of polyvinyl chloride (PVC) color films. In order to achieve the above objectives, it solves the problem of insufficient cutting flexibility in existing PVC color film slitting machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a film slitting machine for producing polyvinyl chloride (PVC) color films, comprising a worktable and a cutting mechanism. The cutting mechanism is fixedly connected to the rear side wall of the worktable. The cutting mechanism specifically comprises a support plate, a fixed plate, a first electric push rod, a slider, a slide groove, a second electric push rod, a connecting flange, a connecting rod, and a cutting blade. The support plate is fixedly connected to the rear side wall of the worktable, and a fixed plate is fixedly connected to the support plate. A slide groove is formed on the front side of the fixed plate. A first electric push rod is fixedly connected to the top of the front side of the fixed plate. A slider is fixedly connected to the telescopic end of the first electric push rod by bolts. The slider is slidably connected to the slide groove. A second electric push rod is fixedly connected to the outer wall of the slider. A connecting flange is connected to the top of the second electric push rod. A connecting rod is fixedly connected to the other end of the connecting flange. A cutting blade is fixedly connected to the bottom of the connecting rod.

[0006] Furthermore, it also includes a feeding mechanism, which is fixedly connected to one side of the workbench.

[0007] Furthermore, the feeding mechanism includes a mounting plate, a servo motor, a first rotating roller, a first toothed disc, a second rotating roller, and a second toothed disc. The top of the left side wall of the worktable is symmetrically connected to the mounting plate. The top of the two mounting plates are provided with the first rotating roller and the second rotating roller near one side. The second rotating roller and the first rotating roller are distributed in sequence at their upper and lower ends. The outer wall of the mounting plate is provided with the servo motor. The output shaft of the servo motor passes through the mounting plate and is connected to the first rotating roller. The outer wall of the rotating roller is fitted with the first toothed disc, and the outer wall of the second rotating roller is fitted with the second toothed disc. The first toothed disc and the second toothed disc are meshed together.

[0008] Specifically, this design leaves a gap between the first and second rollers. When the colored film passes through the gap, the two rollers stably transport the colored film through friction, avoiding slippage or deviation during the transport process, thus ensuring the stability and accuracy of the feeding. The servo motor has precise control performance and can flexibly adjust the feeding speed according to the working requirements of the slitting machine, so that the feeding speed matches the cutting process, further improving the slitting quality.

[0009] Furthermore, the feeding mechanism has a conveying roller on the left side and a guide roller on the right side, and both the conveying roller and the guide roller are located on the worktable.

[0010] Specifically, this design features conveyor rollers that smoothly transport the colored film to be slit to the feeding mechanism, providing a stable supply of colored film. Guide rollers, on the other hand, guide the slit colored film to be output smoothly, ensuring that all stages of the slitting process are closely connected, smooth, and orderly, thus improving the overall operating efficiency of the equipment. The placement of conveyor rollers and guide rollers helps maintain the flatness and tension of the colored film during the conveying process, preventing problems such as wrinkles and twists, and ensuring the slitting quality.

[0011] Furthermore, the workbench is provided with support legs at the four corners of its bottom, and the bottom of the four support legs is provided with locking casters.

[0012] Specifically, this design locks the casters, allowing the slitting machine to move easily within the production area. When it is necessary to adjust the equipment position, plan the site, or perform equipment maintenance, the equipment can be easily moved to a designated location.

[0013] Furthermore, a set of symmetrically arranged guide plates are provided on the right side wall of the workbench, and a feeding chamber is formed between the two guide plates;

[0014] Specifically, the feeding chamber formed by the guide plate in this design guides the cut colored film, allowing it to be output smoothly in the predetermined direction, avoiding deviation or wrinkles during output, thus improving the appearance quality of the product and the convenience of subsequent packaging, transportation and other processes.

[0015] Furthermore, a gap is left between the first and second rotating rollers, and both side walls of the conveying roller and the guide roller are connected to the worktable through connecting plates;

[0016] Specifically, the gap between the first and second rollers in this design provides a suitable conveying channel for the color film, ensuring that the color film can pass smoothly through the feeding mechanism, while avoiding damage to the color film due to excessive squeezing by the rollers.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In the cutting mechanism of this utility model, the first electric push rod drives the slider to slide within the groove, allowing the second electric push rod connected to the slider and the cutting blade to move horizontally. By controlling the extension and retraction of the first electric push rod, the horizontal position of the cutting blade can be precisely adjusted, thereby adapting to the slitting requirements of PVC color films of different widths and improving the versatility and applicability of the slitting machine. The second electric push rod can drive the connecting flange, connecting rod, and cutting blade to move vertically. During the cutting process, the height of the cutting blade can be flexibly adjusted according to the thickness of the color film and the cutting process requirements, ensuring the consistency and stability of the cutting effect.

[0019] 2. The feeding mechanism of this utility model uses a servo motor to drive the first rotating roller to rotate. The first toothed disc on the first rotating roller meshes with the second toothed disc on the second rotating roller, thereby driving the second rotating roller to rotate synchronously. The first and second rotating rollers are distributed vertically with a gap between them. When the polyvinyl chloride colored film passes through the gap, the two rotating rollers can generate a stable frictional force on the colored film, realizing stable and uniform feeding and ensuring the continuity and accuracy of the slitting process.

[0027] It also includes a feeding mechanism 6, which is fixedly connected to one side of the workbench 1.

[0028] The feeding mechanism 6 includes a mounting plate 601, a servo motor 602, a first rotating roller 603, a first geared disc 604, a second rotating roller 606, and a second geared disc 605. The mounting plates 601 are symmetrically connected to the top of the left side wall of the worktable 1. The first rotating roller 603 and the second rotating roller 606 are arranged on the top of one side of the two mounting plates 601. The second rotating roller 606 and the first rotating roller 603 are arranged in a vertical sequence. The servo motor 602 is arranged on the outer wall of the mounting plate 601. The output shaft of the servo motor 602 passes through the mounting plate 601 and is connected to the first rotating roller 603. The first geared disc 604 is sleeved on one side of the outer wall of the first rotating roller 603, and the second geared disc 605 is sleeved on one side of the outer wall of the second rotating roller 606. The first geared disc 604 and the second geared disc 605 are meshed together.

[0029] Among them, the left side of the feeding mechanism 6 is provided with a conveying roller 5, and the right side of the feeding mechanism 6 is provided with a guide roller 7, and both the conveying roller 5 and the guide roller 7 are located on the worktable 1.

[0030] Among them: the bottom of the workbench 1 is provided with four support legs 2, and the bottom of the four support legs 2 is provided with locking casters 3.

[0031] Among them: a set of symmetrically arranged guide plates 8 are provided on the right side wall of the workbench 1, and a feeding chamber is formed between the two guide plates 8.

[0032] Wherein: there is a gap between the first rotating roller 603 and the second rotating roller 606, and the two side walls of the conveying roller 5 and the guide roller 7 are connected to the worktable 1 through connecting plates.

[0033] The working principle of the above embodiment is as follows: the slitting machine is moved to a suitable working position by locking the universal wheels 3 on the bottom support legs 2 of the workbench 1, and then the universal wheels are locked.
