Description

Technical Field

[0001] This utility model belongs to the field of reflective film winding, specifically, it relates to a winding device for reflective film production. Background Technology

[0002] A reflective film winding device is a device used to wind and rewind reflective film to facilitate its subsequent packaging, transportation, and storage.

[0003] Chinese Patent CN220664317U discloses a reflective film winding device, comprising: a main frame, a traction roller rotatably connected to the inner wall of the main frame, a first servo motor fixedly connected to the side wall of the main frame, a first rotating shaft fixedly connected to the side wall of the first servo motor, a take-up roller inserted into the side wall of the first rotating shaft, and a dust collection assembly fixedly connected to the inner wall of the main frame. This application uses a dust collection roller to press the reflective film in the middle, which not only flattens the reflective film but also removes dust from the upper and lower surfaces of the reflective film through suction holes. However, in long-term use, dust easily adheres to the inner wall of the dust collection roller, or the suction holes become clogged. Since the dust collection roller is inconvenient to disassemble, replace, or clean, it can easily affect the winding efficiency or dust removal effect of the reflective film. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a winding device for the production of reflective film, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A winding device for producing reflective film, comprising:

[0007] The base plate is equipped with a support frame and a winding mechanism. Electric push rods are installed on the base plate and the upper part of the support frame. The output shaft of the electric push rod is fixedly fitted with an extension plate. Support frames are installed at both ends of the extension plate.

[0008] A multi-hole vacuum cleaner cylinder runs horizontally through both support frames. A clamping mechanism for holding the multi-hole vacuum cleaner cylinder is elastically fitted inside the support frames. A hand-tightening screw that engages with the clamping mechanism is threaded on one side of the support frames.

[0009] An air extraction mechanism is installed on the side of the support frame. Connectors are installed on both the upper and lower sides of the air extraction mechanism and are connected to it. The connectors are threaded into the end of the multi-hole dust collection cylinder.

[0010] Optionally, the clamping mechanism is a movable clamping block that is elastically and slidably fitted within the support frame, and a fixed clamping block is installed inside the support frame.

[0011] Optionally, two first bearings are installed around the periphery of the porous dust collection cylinder, and the first bearings are clamped between the fixed clamping block and the movable clamping block.

[0012] Optionally, the movable clamping block is equipped with a stop on its side to impede the axial displacement of the first bearing.

[0013] Optionally, the support frame has a slot on the side away from the suction mechanism for taking out and putting in the multi-hole vacuum cleaner cylinder.

Detailed Implementation

[0037] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Please see Figure 1-5 As shown, this embodiment provides a winding device for producing reflective film, including:

[0039] The base plate 1 is equipped with a support frame 103 and a winding mechanism 9. Both the base plate 1 and the support frame 103 are equipped with electric push rods 4. The stroke range of the electric push rods 4 is 100-300mm, which can adapt to reflective films of different thicknesses. The output shaft of the electric push rods 4 is fixedly fitted with an extension plate 6. Both ends of the extension plate 6 are equipped with support frames 601.

[0040] A multi-hole vacuum cleaner tube 5 extends horizontally through both support frames 601. The diameter of the multi-hole vacuum cleaner tube 5 is 0.5-1.2mm, and the porosity is 15%-25%, avoiding the problems of easy clogging due to too small a diameter and poor vacuuming effect due to too large a diameter. A clamping mechanism 7 is elastically fitted inside the support frame 601 to hold the multi-hole vacuum cleaner tube 5. A hand-tightening screw 8 is threaded on one side of the support frame 601 to abut against the clamping mechanism 7.

[0041] The suction mechanism 2 is installed on the side of the support frame 103. The upper and lower sides of the suction mechanism 2 are equipped with connecting parts 3 that communicate with it, and the connecting parts 3 are threadedly fitted to the end of the multi-hole dust collection cylinder 5.

[0042] Optionally, two first support plates 101 are mounted on the base plate 1, and a traction roller 102 is rotatably engaged between the upper parts of the two first support plates 101. A porous dust collection cylinder 5 is located between the traction roller 102 and the winding mechanism 9. The cooperation between the traction roller 102 and the porous dust collection cylinder 5 facilitates the smooth transition of the reflective film to the dust removal station, improves the tension of the film material, and reduces the risk of deviation during the winding process.

[0043] One application of this embodiment is as follows: When it is necessary to replace or clean the multi-hole vacuum cleaner 5, first firmly grasp the multi-hole vacuum cleaner 5, and then unscrew the connector 3 from the end of the multi-hole vacuum cleaner 5; next, loosen the thumbscrew 8 to release the tight clamping mechanism 7; at this time, due to the elastic force, the clamping mechanism 7 will quickly spring back to its original position, releasing the clamping of the multi-hole vacuum cleaner 5, so that the multi-hole vacuum cleaner 5 can be pulled out from the support frame 601, completing the disassembly process; similarly, referring to the above steps, a new or clean multi-hole vacuum cleaner 5 can also be installed back. It should be noted that all electrical devices involved in this application can be powered by a battery or an external power source.

[0044] Through the elastic cooperation of the clamping mechanism 7, when the hand-tightening screw 8 is loosened, the clamping mechanism 7 is quickly reset by the elastic force, thereby releasing the clamp on the multi-hole vacuum cleaner 5, realizing the quick disassembly and assembly of the multi-hole vacuum cleaner 5, improving the convenience of replacing or cleaning the multi-hole vacuum cleaner 5, and reducing the impact on the dust removal effect and winding efficiency of the reflective film. Through the threaded engagement of the connector 3 at the end of the multi-hole vacuum cleaner 5, the multi-hole vacuum cleaner 5 can be quickly connected and disconnected from the suction mechanism 2.

[0045] like Figure 4 ,5 As shown, the clamping mechanism 7 in this embodiment is a movable clamping block 701 that is elastically and slidably fitted within the support frame 601, and a fixed clamping block 606 is installed inside the support frame 601. Optionally, the support frame 601 is provided with a horizontal sliding groove 602 that penetrates through the support frame 601, and the porous vacuum cleaner 5 penetrates horizontally through the sliding groove 602. The movable clamping block 701 is slidably fitted within the sliding groove 602, and the fixed clamping block 606 is installed within the sliding groove 602. Optionally, the support frame 601 has a screw hole 605 and two channels 604 on one side. The screw hole 605 is located between the upper and lower channels 604 and communicates with the slide groove 602. The threaded part of the hand screw 8 is engaged in the screw hole 605. A guide hole 603 is provided between the channel 604 and the slide groove 602. Two guide rods 703 are installed on the side of the movable clamping block 701 away from the fixed clamping block 606. The guide rods 703 pass through the guide hole 603 laterally. A pressure plate 704 is provided at the end of the guide hole 603 and is slidably engaged in the channel 604. A spring 705 is installed between the pressure plate 704 and one end face of the channel 604. The spring 705 is sleeved on the periphery of the guide rod 703. The elastic coefficient of the spring 705 is 8~12N / mm, which provides sufficient clamping force while ensuring the convenience of manual operation. The spring 705's elasticity allows for quick release of the clamp on the multi-hole vacuum cleaner cylinder 5 after the hand screw 8 is loosened, while the pressure plate 704 and the channel 604 work together to stabilize the movement of the spring 705.

[0046] like Figure 3-5 As shown, in this embodiment, the porous vacuum cleaner cylinder 5 is equipped with two first bearings 501 on its periphery. The first bearings 501 and the porous vacuum cleaner cylinder 5 are fitted with an H7 / g6 clearance to ensure rotational accuracy while preventing thermal expansion and jamming. The first bearings 501 are clamped between the fixed clamping block 606 and the movable clamping block 701. Optionally, the movable clamping block 701 is equipped with a stop block 702 on its side to impede the axial displacement of the first bearings 501. The stop block 702 fits against the outer ring end face of the first bearings 501, and the two first bearings 501 of the porous vacuum cleaner cylinder 5 are located between the two stop blocks 702. The stop block 702 facilitates the constraint of the axial displacement of the porous vacuum cleaner cylinder 5, and at the same time, works with the first bearings 501 to improve the rotational stability of the porous vacuum cleaner cylinder 5.

[0047] like Figure 1 , 2 As shown, in this embodiment, the support frame 103 has a disassembly slot 104 for taking and placing the porous vacuum cleaner 5 on the side away from the suction mechanism 2. The vertical cross-section of the support frame 103 is an inverted U-shaped structure, and the disassembly slot 104 extends through the inner side of the support frame 103. By providing the disassembly slot 104, it is convenient for operators to directly take and place the porous vacuum cleaner 5 from the side of the support frame 103, reducing spatial interference during disassembly and assembly operations.

[0048] like Figure 3As shown, the air extraction mechanism 2 in this embodiment includes a square box 201 mounted on one side of the support frame 103. A first motor 204 is mounted on one side of the inner wall of the square box 201. An extension rod 205 is fixedly fitted to the output shaft of the first motor 204, and a fan blade 206 is mounted at the end of the extension rod 205. Optionally, a slot 202 penetrating the hollow area of ​​the square box 201 is provided on the side. A filter plate 203 for intercepting dust flying out of the square box 201 is engaged in the slot 202. The fan blade 206 is located between the filter plate 203 and the first motor 204. The air extraction mechanism 2 can also be an industrial dust collector from the prior art. The operation of the first motor 204 drives the extension rod 205 and the fan blade 206 to rotate, thereby drawing air from the porous dust collection cylinder 5 through the connector 3. At the same time, the detachable snap-fit ​​design of the filter plate 203 facilitates the interception and centralized treatment of dust sucked into the square box 201.

[0049] like Figure 3 As shown, the connector 3 in this embodiment includes a tube 301 mounted on a square box 201. The tube 301 communicates with the square box 201, and the communication port between the tube 301 and the square box 201 is located between the fan blade 206 and the first motor 204, reducing dust contamination of the first motor 204. An internally threaded connector 303 is rotatably fitted to the end of the tube 301, and the internally threaded connector 303 is threaded into the end of the porous vacuum cleaner cylinder 5. Optionally, a second bearing 302 is mounted on the circumference of one end of the tube 301, and the second bearing 302 is embedded in the internally threaded connector 303. The relative rotation between the internally threaded connector 303 and the tube 301 is achieved through the second bearing 302, which facilitates the prevention of kinking of the tube 301 when tightening the internally threaded connector 303.

[0050] like Figure 1 As shown, the winding mechanism 9 in this embodiment includes a second support plate 105 mounted on the base plate 1. A second motor 901 is mounted on the upper part of the second support plate 105. The output shaft of the second motor 901 is fixedly fitted with a rotating shaft 902. A take-up roller 903 is detachably mounted on the periphery of the rotating shaft 902. The take-up roller 903 can be detached and installed using common structures such as snaps, bolts, or magnetic attraction. The second motor 901 directly drives the rotating shaft 902, causing the rotating shaft 902 to drive the take-up roller 903 to rotate, thereby enabling the take-up roller 903 to wind up the dust-removed reflective film.
