Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Example 1: As Figures 1-5 ,include:

[0027] The base 100 has an arc-shaped groove 110 on the top inner wall and side plates 120 fixedly installed on the top of both sides of the base 100.

[0028] The positioning assembly includes a positive and negative threaded screw 200, and threaded slides 220 and push plates 230 on the outer walls of both sides of the positive and negative threaded screw 200.

[0029] The feeding assembly includes a feeding roller 300, which is rotatably connected to the side plate 120 via bearings.

[0030] The specific application scenario of this embodiment is as follows: the base 100 serves as the support structure for the entire device, providing stable support for other components. The arc-shaped groove 110 opened on its top inner wall may be used to accommodate some moving parts or to provide specific path guidance for the delivery of the laser film. The side plates 120 fixed on the top of both sides provide the installation foundation and support for the positioning component and the feeding component.

[0031] The lead screw 200 in the positioning assembly is the core component. The lead screw 200 is a specially designed screw with opposite thread directions on both sides. When the lead screw 200 rotates, the slide 220 connected to it will move in opposite directions along the lead screw. The push plate 230 fixed on the slide 220 will move with the slide 220, thereby achieving positioning and clamping of both sides of the laser film.

[0032] The feeding roller 300 in the feeding assembly is rotatably connected to the side plate 120 through a bearing. In this way, the feeding roller 300 can rotate freely under the support of the side plate 120. When the feeding roller 300 rotates, it can play the role of transmission and feeding of the laser film, and transport the laser film to the designated position for production processing.

[0033] Example 2: Figures 3-5 The positive and negative threaded screws 200 are rotatably connected to the inner walls of the two side plates 120 via bearings. The shafts at both ends of the positive and negative threaded screws 200 extend to the outside through the side plates 120. There are two positive and negative threaded screws 200. The outer walls of the two positive and negative threaded screws 200 are connected by a first synchronous pulley 240 and a first synchronous belt 250. A handwheel 260 is fixedly installed on the outer wall of the positive and negative threaded screws 200 away from the first synchronous pulley 240. A guide rod 210 is provided below the positive and negative threaded screws 200. The guide rod 210 is fixedly installed between the two side plates 120 and is located inside the arc groove 110. A push plate 230 is fixedly installed on the outer wall of the opposite side of the two slides 220. The surface of the push plate 230 is provided with a protective pad. The inner walls of the slides 220 and the push plate 230 are slidably connected to the outer walls of the positive and negative threaded screws 200. The push plate 230 engages and limits the outer walls of the laser film on both sides.

[0034] The specific application scenario of this embodiment is as follows: Two positive and negative threaded screws 200 are connected by a first synchronous pulley 240 and a first synchronous belt 250. This connection method ensures that the two positive and negative threaded screws 200 can rotate synchronously. When the operator turns the handwheel 260, the handwheel 260 drives the connected positive and negative threaded screw 200 to rotate. Through the synchronous belt drive, the other positive and negative threaded screw 200 will also rotate synchronously. The guide rod 210 is fixedly installed between the two side plates 120 and located inside the arc groove 110. The slide 220 is not only screwed with the positive and negative threaded screws 200 The threaded connection also slides with the guide rod 210. The guide rod 210 guides and stabilizes the movement of the slide 220, preventing the slide 220 from shifting or shaking during movement. When the forward and reverse threaded screws 200 rotate, the slide 220 moves linearly along the guide rod 210, thereby driving the push plate 230 to move. The protective pad on the surface of the push plate 230 can prevent damage to the surface of the laser film when it is snapped into place. Through the opposite movement of the push plate 230, the outer walls on both sides of the laser film can be accurately snapped into place, realizing the positioning function of the laser film.

[0035] Example 3: Figure 3 and Figure 5 Two feeding rollers 300 are provided, and the ends of the two feeding rollers 300 extend to the outside of the side plate 120. The outer walls of the two feeding rollers 300 are connected by a second synchronous pulley 310 and a second synchronous belt 320. A servo motor 340 is fixedly installed on the outer wall of the base 100. The outer wall of the output shaft of the servo motor 340 is connected to the outer wall of the feeding rollers 300 by gear meshing. The outer wall of the feeding rollers 300 feeds the laser film.

[0036] The specific application scenario of this embodiment is as follows: The servo motor 340, which is fixedly installed on the outer wall of the base 100, serves as a power source. The outer wall of its output shaft is connected to the outer wall of the feeding roller 300 through gear meshing. When the servo motor 340 starts, the rotation of the motor output shaft is transmitted to the feeding roller 300 through the gear, causing the feeding roller 300 to start rotating. Since the feeding roller 300 is in contact with the laser film, under the action of friction, the rotation of the feeding roller 300 will drive the laser film to move forward, thereby realizing the transmission and feeding function of the laser film. The operator can precisely control the feeding speed and direction of the laser film by controlling the speed and direction of the servo motor 340 to meet different production needs.

[0037] The working principle of this utility model is as follows: When used by those skilled in the art, the precise positioning and stable feeding of the laser film are achieved through the coordinated operation of the base 100, positioning component, and feeding component. The base 100 provides stable support, and the arc groove 110 and side plate 120 lay the foundation for the installation and operation of other components. During positioning, the handwheel 260 is rotated to drive the positive and negative threaded screws 200 to rotate. The two screws are linked through the first synchronous pulley 240 and the first synchronous belt 250. Under the guidance of the guide rod 210, the slide 220 causes the push plate 230 to move in opposite directions. The protective pad on the surface of the push plate 230 can avoid damage to the laser film, thereby locking and limiting the laser film on both sides to complete the positioning. During the feeding process, the servo motor 340 serves as a power source and transmits power to the feeding roller 300 through gear meshing. The two feeding rollers 300 rotate synchronously through the second synchronous pulley 310 and the second synchronous belt 320. Under the action of friction, the laser film is stably conveyed, meeting the requirements of each stage of production and processing for the position and conveying of the laser film.
