Abstract
Description
Technical Field
[0001] This utility model relates to the field of resistive film production technology, specifically to a winding mechanism for resistive film production. Background Technology
[0002] The resistive film is the main part of the resistor and can impede the flow of current. It is formed by depositing resistive materials onto the surface of insulating materials through processes such as vacuum evaporation and magnetron sputtering. Usually, the resistive film needs to be rolled up according to customer requirements after production.
[0003] According to the Chinese patent publication CN221295515U, "A winding mechanism for resistive film production", the main feature described is that it can automatically and evenly wind resistive film. When the resistive film is fully wound, the winding drum can be replaced to continue working, thus meeting production needs. By setting up a winding mechanism, the winding drum can be quickly replaced, which is convenient for storage and transportation. The quick replacement of the winding drum also facilitates subsequent storage and transportation, ensuring that the needs of resistive film production are met.
[0004] During the production process, the resistive film needs to be wound up by a take-up roller and then cut with a cutter. After that, the wound resistive film and the take-up roller are disassembled. Then, one end of the resistive film to be cut is manually pulled and connected to the new take-up roller. This process requires manual pulling of the end of the resistive film to make the end of the resistive film flat when connecting to the new take-up roller, which can easily reduce the winding efficiency.
[0005] Therefore, a winding mechanism for resistive film production is proposed to solve the problem that when winding a new resistive film, it is necessary to adjust one end of the resistive film to make close contact with the new winding roller, which leads to a decrease in winding efficiency. Utility Model Content
[0006] The technical problem to be solved by this utility model is that when winding a new resistive film, it is necessary to adjust one end of the resistive film to make close contact with the new winding roller, which leads to a decrease in winding efficiency. Therefore, a winding mechanism for resistive film production is proposed.
[0007] The technical solution adopted by this utility model to solve the technical problem is: a winding mechanism for resistive film production, including a fixed plate, guide wheels, a base, a first motor, a bidirectional lead screw, a moving plate, an electric push rod, a clamping plate, and a winding roller. The guide wheels contact the film body. The fixed plate has a first groove. A first spring rod is fixedly connected to both the upper and lower sides of the first groove. A moving frame is sleeved on the first spring rod. A contact roller is rotatably connected inside the moving frame. A pressure roller is provided on the upper side of the contact roller. An electric telescopic rod is fixedly connected to one side of the moving frame. A cutter is fixedly connected to the output end of the electric telescopic rod. A clamping frame is fixedly connected to one side of the moving frame. A cutter holder contacts inside the clamping frame. A second groove is opened on both sides of the moving frame. A second spring rod is fixedly connected to the second groove. A slider is sleeved on the second spring rod. A tension roller is rotatably connected between two adjacent sliders.
[0008] As a preferred technical solution of this utility model, a support plate is fixedly connected to one side of the movable frame, an adjusting rod is rotatably connected to the support plate, a connecting frame is rotatably connected to the bottom side of the adjusting rod, and a pressure roller is rotatably connected inside the connecting frame. Rotating the adjusting rod can drive the connecting frame and the pressure roller to move closer to the contact roller, thereby adapting to different resistive film thicknesses.
[0009] As a preferred technical solution of this utility model, a limiting roller is rotatably connected inside the movable frame. The limiting roller is located on the bottom side of the contact roller, and a folding structure can be formed by setting a limiting hole.
[0010] As a preferred technical solution of this utility model, a contact strip is fixedly connected to one side of the movable frame. The contact strip is fixedly connected to the card frame. The inclination of the contact strip is consistent with that of the cutter. By setting the contact strip, the contact surface with the cutter is increased, thereby providing a limit for the end of the resistor film to be cut after cutting.
[0011] As a preferred technical solution of this utility model, a spring telescopic rod is fixedly connected inside the card frame, and one end of the spring telescopic rod is fixedly connected to the knife holder. By setting the spring telescopic rod, a rebound effect is provided, which can move one end of the resistive film out.
[0012] This utility model has the following advantages: by opening a first groove on the fixed plate and cooperating with a first spring rod to move the moving frame, and by limiting and guiding the film body through the pressure roller and contact roller, after the cutter cuts it, one end of the resistance film to be cut is limited by the pressure roller and contact roller, which can facilitate the export. At the same time, when replacing a new winding roller, the first spring rod will drive the moving frame to approach the clamping plate, thereby achieving the effect of easy connection and improving winding efficiency.

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] Please refer to the following: Figure 1-3 The winding mechanism for resistive film production shown includes a fixed plate 1, guide wheels 2, a base 3, a first motor, a bidirectional lead screw 4, a shifting plate 5, an electric push rod 6, a clamping plate 7, and a winding roller 8. The first motor drives the bidirectional lead screw 4 to rotate, which causes the shifting plate 5 to move relative to the base. Under the action of the electric push rod 6, the clamping plate 7 and the winding roller 8 move up and down. The guide wheels 2 contact the film body 9. The fixed plate 1 has a first groove 10. First spring rods 11 are fixedly connected to the upper and lower sides of the first groove 10. The springs on the first spring rods 11 are located at... Figure 1On the left side of the moving frame 12, in conjunction with the take-up roller 8, the end of the film 9 is brought closer to the take-up roller 8. The moving frame 12 is sleeved on the first spring rod 11. A contact roller 13 is rotatably connected inside the moving frame 12. Both the contact roller 13 and the pressure roller 14 are equipped with drive motors on one side, and are driven by the drive motors. The contact roller 13 is at the same height as the take-up roller 8 and can contact it. The pressure roller 14 is provided on the upper side of the contact roller 13. An electric telescopic rod 15 is fixedly connected to one side of the moving frame 12. The extension and retraction of the electric telescopic rod 15 can drive the cutter 16 to contact the cutter holder 19, thereby cutting. The electric telescopic rod 15 has a cutter 16 fixedly connected to its output end. A retaining frame 17 is fixedly connected to one side of the moving frame 12. A cutter holder 19 is in contact with the retaining frame 17. A second groove 20 is provided on both sides of the moving frame 12. A second spring rod 21 is fixedly connected to the second groove 20. The spring on the second spring rod 21 is located to the right of the slider 22. Under the action of the second spring rod 21, the flexible fiber will be increased, making the winding roller 8 winding more tightly. A slider 22 is sleeved on the second spring rod 21. A tension roller 23 is rotatably connected between two adjacent sliders 22.
[0018] Among them, a support plate 24 is fixedly connected to one side of the movable frame 12, an adjusting rod 25 is rotatably connected to the support plate 24, a connecting frame 26 is rotatably connected to the bottom side of the adjusting rod 25, and a pressure roller 14 is rotatably connected inside the connecting frame 26. Rotating the adjusting rod 25 can drive the pressure roller 14 to move down, and in conjunction with the contact roller 13, it can limit the film 9 of different thicknesses.
[0019] The movable frame 12 is rotatably connected to a limiting roller 27, which is located on the bottom side of the contact roller 13. By setting the limiting roller 27, the contact surface with the film body 9 can be increased, which facilitates subsequent connection.
[0020] The movable frame 12 is fixedly connected to one side of a contact strip 28, which is fixedly connected to the card frame 17. The contact strip 28 has the same inclination as the cutter 16. By setting the contact strip 28, the contact surface with the cutter 16 can be increased, so that when the membrane 9 is cut, the end of the membrane 9 on the cutter 16 will be limited, thus maintaining the stability of the end of the membrane 9.
[0021] The frame 17 is fixedly connected to a spring telescopic rod 18, one end of which is fixedly connected to the blade holder 19. By setting the spring telescopic rod 18, the end of the membrane 9 located on the upper side of the cutter 16 can be disengaged from the blade holder 19 by the rebound force.
[0022] Working principle: The new take-up roller 8 is placed between two adjacent clamping plates 7. At this time, the moving frame 12 moves to the side of the take-up roller 8 under the action of the first spring rod 11, and drives the film body 9 to contact the take-up roller 8 near the end, so that the joint is flush. Then, it is connected by manual fixing. At this time, the drive motor on the clamping plate 7 and the pressure roller 14 rotates, which can cause the film body 9 to move and be wound on the take-up roller 8. After the winding length is appropriate, the electric telescopic rod 15 extends, and the cutter 16 enters the cutter holder 19. At this time, the film body 9 on the upper side of the cutter holder 19 contacts the contact strip 28. After the cutting is completed, the end of the film body 9 automatically hangs down under the action of gravity. At this time, the film body 9 on the right side of the contact roller 13 contacts the take-up roller 8 under the action of the first spring rod 11, which can provide a precise contact surface to facilitate the fixing effect. The take-up roller 8 can be disassembled by the retraction of the electric push rod 6 and the mutual separation of the moving plates 5.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
