Description
Technical Field
[0001] This utility model relates to the technical field of decorative film production, and in particular to a variable width adaptive feeding traction device. Background Technology
[0002] In the processing and production of decorative film materials, the feeding and traction device is a key piece of equipment to ensure production continuity and processing accuracy. The function of the feeding and traction device is to pull out the formed decorative film during the production and processing process, so as to facilitate the unfolding and retraction of the decorative film.
[0003] However, traditional traction devices typically employ a fixed width design or a mechanical structure that requires cumbersome manual adjustments, making it difficult to adapt to the frequently changing material width requirements in production and severely restricting the flexibility and efficiency of the production line. On the other hand, during the feeding process, the pressure plate comes into contact with the film material, and due to the film material's stickiness or static electricity, the film material easily adheres to the surface of the pressure plate, requiring manual separation, which brings inconvenience to the operation. Utility Model Content

This solves the problem that traditional devices are difficult to adapt to changes in width. Furthermore, the pressure plate one and pressure plate two move alternately through a telescopic mechanism, which prevents the film material from sticking to the pressure plate, eliminates the need for manual separation, and improves the convenience and efficiency of decorative film processing.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0017] Secondly, the term "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0018] Example: Reference Figures 1-2 This embodiment provides a variable width adaptive feeding traction device, including: The moving plate 1 is driven by the moving mechanism 2 and moves along the length of the film. To improve stability, two moving plates 1 are symmetrically arranged, and several rollers 3 are arranged between the two moving plates 1. The film passes through the rollers 3 when it moves, and the rollers 3 provide rotational support for the film. Gantry 4 is fixed on the movable plate 1 and is erected along the width of the membrane. There are two sliders 5, which slide along the length of the gantry frame 4. Adjustment blocks 6 are provided on sliders 5. The power mechanism 7 is mounted on the gantry 4 and is used to drive the two sliders 5 to move in opposite directions; The adjusting block 6 is equipped with a telescopic mechanism 1 8 and a telescopic mechanism 2 9. The output end of the telescopic mechanism 1 8 is equipped with a pressure plate 10, which has a through hole 11. The through hole 11 is set vertically. The telescopic mechanism 2 9 is equipped with a pressure plate 2 12, which slides at the through hole 11 under the drive of the telescopic mechanism 2 9. More specifically, the telescopic mechanism 1 8 and the telescopic mechanism 2 9 can be selected from cylinders, hydraulic cylinders or electric telescopic rods, etc. Both are set in a vertical direction. The purpose is to drive the pressure plate 10 and the pressure plate 2 12 to move closer to the support plate 13, so that the membrane can be clamped in cooperation with the support plate 13. Support plate 13 is set on movable plate 1. Pressure plate 10 and pressure plate 2 are both above support plate 13, as shown in the figure. Notches are made on movable plate 1, and both ends of support plate 13 are inserted into the notches and fixed with bolts, etc. The specific working process of this device is as follows: When film traction is required, the moving mechanism 2 is operated to move the moving plate 1 and the gantry 4 to the film outlet position, so that the end of the film is mounted on the support plate 13; then the power mechanism 7 on the gantry 4 is activated to drive the two sliders 5 to slide in the opposite direction along the gantry 4, adjusting to the appropriate spacing according to the width of the film; then the telescopic mechanism 8 and the telescopic mechanism 9 on the adjusting block 6 are controlled to move vertically downwards in sync, driving the pressure plate 10 and the pressure plate 12 to move closer to the support plate 13, cooperating with the support plate 13 to simultaneously press the end of the film material, and then the moving machine is operated. Mechanism 2 continuously drives the moving plate 1 to move along the length of the film. The film moves smoothly under the rotational support of the roller 3 between the two moving plates 1, realizing continuous and stable feeding and traction. When it is necessary to release the film material to continue traction, first control the telescopic mechanism 8 to drive the pressure plate 10 to lift upward, and then control the telescopic mechanism 9 to reset, driving the pressure plate 12 to lift upward. During this process, since the pressure plate 12 is still in contact with the film, the pressure plate 10 can be separated from the film. Moreover, since the contact area between the pressure plate 12 and the film is small, the probability of the film material adhering to it is lower, which can effectively avoid the problem of film material adhesion.
[0019] If the membrane shifts, pressure plate 10 and pressure plate 2 12 may not be able to adapt to the end position of the membrane. (Refer to...) Figure 2 As a preferred embodiment of this utility model, the slider 5 is fixed with a track 14 arranged along the width direction of the film, the adjusting block 6 slides on the track 14, and a handle for locking its position is provided on the adjusting block 6. More specifically, after the slider 5 is adjusted according to the film width, if the film shifts during the feeding process, there is no need to readjust the overall position of the slider 5. Simply slide the adjusting block 6 to match the end position of the film along the track 14. After adjustment, lock the adjusting block 6 with the handle. The operation is convenient and flexible, and can quickly deal with the film shift problem.
[0020] As a preferred embodiment of this utility model, refer to Figure 4The bottom of the pressure plate 12 has a protrusion 15; More specifically, the protrusion 15 is spherical, which makes point contact between the protrusion 15 and the film, further reducing the contact area with the film. The point contact form can reduce the contact area between the pressure plate 2 12 and the film material, further reducing the possibility of the film material adhering to the pressure plate 2 12 due to stickiness or electrostatic adhesion.
[0021] As a preferred embodiment of this utility model, refer to Figures 1-3 The power mechanism 7 includes: Two sets of symmetrically arranged linkage mechanisms, each linkage mechanism including a first power rod 71, a second power rod 72, and a support shaft 73 fixed to the gantry frame 4. One end of the first power rod 71 is rotatably connected to the slider 5, and the other end of the first power rod 71 is rotatably connected to one end of the second power rod 72 via a pin 74. More specifically, as shown... Figure 3 As shown, power rod 1 71 and power rod 2 72 form a V-shaped structure; The middle region of the second power rod 72 is rotatably connected to the support shaft 73, and a strip hole 75 is provided at the other end of the second power rod 72. More specifically, the strip hole 75 is provided along the length direction of the second power rod 72. The power mechanism 7 also includes: Telescopic mechanism 3 76 is fixed on gantry frame 4. The output end of telescopic mechanism 3 76 is fixed with two power shafts 77 that pass through two strip holes 75 respectively. Telescopic mechanism 3 76 can be a cylinder, hydraulic cylinder or electric telescopic rod, etc. The operation of the power mechanism 7 of this device is as follows: When the telescopic mechanism 3 76 is started, its output end drives the two power shafts 77 to move along their own axis. The power shafts 77 slide in the strip hole 75 at the end of the power rod 2 72 and push the power rod 2 72 to rotate around the support shaft 73. Since the power rod 2 72 and the power rod 1 71 are rotatably connected by the pin 74, when the power rod 2 72 rotates, it will drive the power rod 1 71 to move synchronously, thereby pulling the two sliders 5 to slide in the opposite direction along the gantry 4. The above structure drives the symmetrical linkage mechanism through the telescopic mechanism 3 76, which can realize the synchronous reverse adjustment of the two sliders 5. The V-shaped linkage structure can stably transmit power and reduce the number of power ends and stroke required. At the same time, the power rod 1 71 and the power rod 2 72 are both set horizontally, which reduces the space occupied.
[0022] As a preferred embodiment of this utility model, refer to Figure 2 and 3 The second power rod 72 is divided into two connected parts with the support shaft 73 as the inflection point, and the included angle between the two parts is 135~175°. The aforementioned angle range avoids the problem of jamming or dead spots when the power rod 1 71 and the power rod 2 72 are linked due to an excessively small angle, ensuring that when the telescopic mechanism 3 76 pushes the power rod 2 72 to rotate through the power shaft 77, the power can be smoothly transmitted to the power rod 1 71 and drive the slider 5 to slide. It also avoids the problem of reduced power transmission efficiency and slower adjustment speed of the slider 5 due to an excessively large angle.
[0023] As a preferred embodiment of this utility model, refer to Figure 3 A reinforcing rod 78 connects the two parts. The reinforcing rod 78 can significantly enhance the overall structural strength and rigidity of the second power rod 72, and prevent deformation or bending at the connection between the two parts due to concentrated force during operation.
[0024] As a preferred embodiment of this utility model, refer to Figure 1 The moving mechanism 2 is a chain and sprocket structure. Using a chain and sprocket structure as the moving mechanism 2 can provide a stable and precise linear driving force for the moving plate 1 and the gantry 4. The chain and sprocket transmission has high efficiency and strong load-bearing capacity, which can adapt to the production needs of long-term continuous operation. Moreover, the structure is simple and easy to maintain, which can ensure that the device can continuously and stably complete the film material traction operation and improve the overall operational reliability.
[0025] As a preferred embodiment of this utility model, refer to Figure 1 The top surface of the support plate 13 facing the film outlet position has a slope. The slope can guide the film material to slide smoothly to the top surface of the support plate 13 without the need for manual adjustment of the film material position, reducing the difficulty of operation. Combined with subsequent clamping and traction actions, it further improves the continuity and efficiency of feeding and traction, ensuring stable production.
[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
