Description
Technical Field
[0001] This utility model relates to the field of coating processing technology, specifically to a substrate tension adjustment mechanism applicable to multi-specification full graphene coating machines. Background Technology
[0002] Currently, graphene coating technology is widely used in the field of high-performance material preparation, which has extremely high requirements for coating uniformity and substrate tension control. Existing coating equipment often uses fixed tensioning mechanisms, which are difficult to adapt to the differentiated tension requirements of various substrates. Especially when processing ultra-thin or elastic substrates, problems such as uneven tension, wrinkling or breakage are prone to occur, directly affecting coating quality and yield. Utility Model Content
[0003] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a reasonably designed and easy-to-use substrate tension adjustment mechanism suitable for multi-specification full graphene coating machines, which can effectively solve the aforementioned defects in existing technologies.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a mounting frame, abutting rollers, and mounting plates. The mounting frame is U-shaped, and mounting plates are symmetrically arranged front and back on the upper side inside the mounting frame. Abutting rollers are arranged on both sides between the front and back mounting plates. It also includes: The movable blocks are four in number and are respectively screwed onto the shafts at both ends of the abutment roller via bearings. The movable blocks are slidably disposed in the slide grooves on both sides of the mounting plate, and the abutment springs connected to the movable blocks are fixed in the slide grooves. Two rotating tubes are provided, and each is fixed to the side of the mounting plate away from the center of the mounting frame. The rotating tubes are screwed onto the vertical plate of the mounting frame via bearings. The drive motor is embedded and fixed in a vertical plate on one side of the mounting bracket, and the output shaft of the drive motor is engaged with the tooth groove on the outer ring wall of the adjacent rotating tube through a gear. The abutment plate consists of two plates, which are symmetrically arranged on both sides inside the mounting frame. The abutment plate is located on the side of the mounting plate away from the vertical plate of the mounting frame. The abutment plate is connected to the vertical plate of the mounting frame through an adjustment mechanism. The waist-shaped hole on the abutment plate is movably fitted onto the abutment roller. The above technical solution involves passing the substrate from the upper side of one abutment roller to the lower side of another abutment roller, where the substrate comes into contact with the abutment roller. The position of the abutment plate is then adjusted by an adjustment mechanism so that the abutment plate contacts the substrate. The drive motor is then started, which drives the connected rotating tube to rotate. The rotating tube drives the mounting plate to rotate, causing the abutment roller to rotate. Under the tension of the substrate, the moving block moves towards the center of the mounting plate, compressing the abutment spring and ensuring the tension of the substrate. This tension can be adjusted over a period of time.
[0005] As a further improvement of this utility model, the moving block abuts against a reset switch on the side away from the abutting spring. The reset switch is embedded and fixed on the inner wall of the slide groove and is connected to the drive motor. With the above technical solution, when the substrate becomes loose, the elastic force of the contact spring pushes the moving block. When the moving block contacts the reset switch, the drive motor can be started through the reset switch to achieve the effect of adjusting the tension.
[0006] As a further improvement of this utility model, the adjustment mechanism includes: The adjusting screws are two in number, and they are respectively screwed into the side wall of the two abutment plates by bearings. The other end of the adjusting screw passes through the round holes on the mounting plate and the vertical plate of the mounting frame in sequence, and is exposed on the outside of the mounting frame. The limiting strips consist of four strips, which are symmetrically embedded and fixed on the upper and lower inner walls of the round hole on the mounting bracket. The limiting strips are movably disposed in the strip groove on the adjusting screw. Two adjusting screws are provided, and each is screwed into the end of the adjusting screw located on the vertical plate of the mounting frame. The adjusting screws are screwed into the vertical plate of the mounting frame via threads. An adjusting motor is embedded and fixed in the horizontal plate of the mounting frame. The output shaft of the adjusting motor is connected to a drive rod through a worm gear pair. The drive rod is screwed into the horizontal plate of the mounting frame through bearings. The two ends of the drive rod are connected to the adjusting screw tubes on both sides through a synchronous wheel transmission assembly. With the above technical solution, the adjusting motor is started, and the adjusting motor drives the drive rod to rotate through the worm gear pair. The two ends of the drive rod drive the adjusting screw tubes on both sides to rotate through the synchronous wheel transmission assembly. When the adjusting screw tubes rotate, the adjusting screw moves due to the limit bar. The adjusting screw drives the abutment plate to move. The abutment plate is screwed to the adjusting screw, so as not to affect the movement of the abutment plate.
[0007] As a further improvement of this utility model, a limiting plate is fixed to the outer end of the adjusting screw, and the limiting plate is set to abut against the vertical plate of the mounting frame. The above technical solution can limit the adjustment screw and prevent it from falling off the mounting bracket.
[0008] As a further improvement of this utility model, the four corners of the bottom wall of the mounting bracket are all fixed with casters, and the casters have their own locking devices. The above technical solution allows the mounting frame to move via casters, and the mounting frame to be limited by a self-locking device.
[0009] As a further improvement of this utility model, each of the anti-collision springs is provided with a guide rod inside, and the two ends of the guide rod are fixedly connected to the inner wall of the slide groove, and the moving block is movably sleeved on the guide rod. The above technical solution facilitates the support of the contact spring, preventing it from deforming.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The substrate tension adjustment mechanism of this utility model, which is applicable to multi-specification full graphene coating machines, can realize automatic compensation and precise control of substrate tension through spring adaptive pressing and motor drive adjustment, effectively preventing deviation and wrinkling, and significantly improving coating uniformity and stability. This utility model has the advantages of reasonable setting and low manufacturing cost. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Example 1: like Figures 1-6 As shown, this embodiment includes a mounting frame 1, abutment rollers 2, and mounting plates 3. The mounting frame 1 is U-shaped, and mounting plates 3 are symmetrically arranged on the upper side of the interior of the mounting frame 1. Abutment rollers 2 are arranged on both sides between the front and rear mounting plates 3. Universal wheels 12 are fixed to the four corners of the bottom wall of the mounting frame 1. The universal wheels 12 have built-in locking devices, allowing the mounting frame 1 to move and limiting its position through self-locking devices. It also includes: The movable blocks 4, of which there are four, are respectively screwed onto the shafts at both ends of the contact roller 2 via bearings. The movable blocks 4 are slidably disposed in the grooves on both sides of the mounting plate 3. The contact springs 5 connected to the movable blocks 4 are welded and fixed in the grooves. Each contact spring 5 is provided with a guide rod 13 inside. The two ends of the guide rod 13 are fixedly connected to the inner wall of the groove. The movable blocks 4 are movably sleeved on the guide rods 13, which can facilitate the support of the contact springs 5 and prevent them from deforming. Rotating tube 6, there are two rotating tubes 6, and they are respectively welded and fixed to the side of the mounting plate 3 away from the center of the mounting frame 1. The rotating tubes 6 are screwed to the vertical plate of the mounting frame 1 through bearings. The drive motor 7 is embedded and fixed in the vertical plate on one side of the mounting bracket 1. The output shaft of the drive motor 7 is engaged with the tooth groove on the outer ring wall of the adjacent rotating tube 6 through a gear. The moving block 4 is in contact with a reset switch 10 on the side away from the contact spring 5. The reset switch 10 is embedded and fixed on the inner wall of the slide groove. The reset switch 10 is connected to the drive motor 7. When the substrate becomes loose, the elastic force of the contact spring 5 pushes the moving block 4. When the moving block 4 contacts the reset switch 10, the drive motor 7 can be started through the reset switch 10 to achieve the effect of adjusting the tension. The abutment plate 8 consists of two plates, which are symmetrically arranged on both sides inside the mounting frame 1. The abutment plate 8 is located on the side of the mounting plate 3 away from the vertical plate of the mounting frame 1. The abutment plate 8 is connected to the vertical plate of the mounting frame 1 through the adjustment mechanism 9. The waist-shaped hole on the abutment plate 8 is movably fitted onto the abutment roller 2.
[0020] Example 2: See Figure 1 , Figure 5-6 As shown, based on Embodiment 1, the adjustment mechanism 9 includes: Two adjusting screws 9-1 are provided, each screwed into the opposite side wall of two contact plates 8 via bearings. The other end of the adjusting screw 9-1 passes through the round holes on the mounting plate 3 and the vertical plate of the mounting bracket 1, and is exposed on the outside of the mounting bracket 1. A limiting plate 11 is welded to the outer end of the adjusting screw 9-1. The limiting plate 11 is engaged with the vertical plate of the mounting bracket 1 to limit the adjusting screw 9-1 and prevent it from falling off the mounting bracket 1. Limiting strips 9-2, there are four limiting strips 9-2, which are symmetrically embedded and welded to the upper and lower inner walls of the round hole on the mounting bracket 1. The limiting strips 9-2 are movably set in the strip groove on the adjusting screw 9-1. There are two adjusting screw tubes 9-3, and they are respectively screwed into the end of the adjusting screw 9-1 located in the vertical plate of the mounting frame 1 by threads. The adjusting screw tubes 9-3 are screwed into the vertical plate of the mounting frame 1 by threads. The adjusting motor 9-4 is embedded and fixed in the horizontal plate of the mounting frame 1. The output shaft of the adjusting motor 9-4 is connected to the drive rod 9-5 through a worm gear pair. The drive rod 9-5 is screwed into the horizontal plate of the mounting frame 1 through bearings. The two ends of the drive rod 9-5 are connected to the adjusting screw tubes 9-3 on both sides through a synchronous wheel transmission assembly.
[0021] When using this utility model, the substrate is passed from the upper side of one abutment roller 2 to the lower side of the other abutment roller 2. At this time, the substrate abuts against the abutment roller 2. Then, the adjusting motor 9-4 is started. The adjusting motor 9-4 drives the drive rod 9-5 to rotate through the worm gear pair. The two ends of the drive rod 9-5 drive the adjusting screw tubes 9-3 on both sides to rotate through the synchronous wheel transmission assembly. When the adjusting screw tube 9-3 rotates, the adjusting screw 9-1 moves due to the limit bar 9-2. The adjusting screw 9-1 drives the abutment plate 8 to move. The abutment plate 8 is screwed to the adjusting screw 9-1, so as not to affect the movement of the abutment plate 8, so that the abutment plate 8 abuts against the substrate. Then, the drive motor 7 is started. The drive motor 7 drives the rotating tube 6 connected to it to rotate. The rotating tube 6 drives the mounting plate 3 to rotate, so that the abutment roller 2 rotates. Under the tight state of the substrate, the moving block 4 moves towards the center of the mounting plate 3, so that the abutment spring 5 is compressed, thereby ensuring the tension of the substrate. It can be adjusted after a period of time.
[0022] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. By pushing the moving block 4 with the contact spring 5, the slight changes in the tightness of the substrate during the transmission process can be automatically compensated, and a constant tension can be maintained to effectively prevent the material from becoming too loose or too tight. 2. The reset switch 10 is linked with the drive motor 7. When the substrate is loose and the switch is triggered, the motor can be automatically started to tighten it, realizing real-time monitoring and closed-loop automatic control of tension, reducing manual intervention. 3. The adjustment mechanism 9, consisting of an adjustment motor 9-4, a worm gear and a timing belt, can precisely and synchronously control the position of the two side contact plates 8, ensuring that the substrate is subjected to uniform force and avoiding deviation or wrinkling. 4. The entire structure is integrated into the U-shaped mounting frame 1, which has a high space utilization rate; the universal wheels 12 are designed for easy movement and positioning, and can quickly adapt to different specifications of substrates and production line layouts, with good flexibility.
[0023] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
