Description

Technical Field

[0001] This utility model relates to an automatic coating machine, and more particularly to an automatic coating machine for double-sided silicone paper. Background Technology

[0002] In modern industrial production, silicone paper is widely used in various fields, such as food packaging and electronic component manufacturing, due to its excellent heat resistance, non-stick properties, and insulation. The production process of silicone paper typically involves uniformly coating its surface with silicone oil or other chemicals to impart specific functions. A double-sided silicone paper automatic coating machine is an automated production device specifically designed for uniformly coating both sides of silicone paper with silicone oil or other coating materials. It has wide applications in the silicone paper processing industry, especially in situations requiring high-quality, high-efficiency production of double-sided coated silicone paper.

[0003] The existing automatic coating machines often produce uneven coating of silicone paper, which is caused by uneven tension at both ends of the coating head. This not only affects the quality of the final product, but may also lead to a decrease in production efficiency and an increase in costs. Utility Model Content

[0004] In order to overcome the shortcomings of uneven coating and uneven tension at both ends of the coating head that often occur when coating silicone paper with existing automatic coating machines, the purpose of this utility model is to provide an automatic double-sided silicone paper coating machine.

[0005] The technical solution of this utility model is as follows: an automatic double-sided silicone paper coating machine, comprising a base, a support, a placement cylinder, a coating roller, a coating head, a screw, a take-up cylinder, a tensioning roller, and a fixing frame. The take-up cylinder is connected to the front top of the base, and the support is located at the rear top of the base. The placement cylinder is connected to the top of the support, and a fixing frame is located in the middle of the top of the base. The fixing frame has symmetrical cavities on its left and right sides. In the upper inner part of the fixing frame, from front to back, a tensioning roller is slidably connected, a coating roller is rotatably connected, and a coating head is fixedly connected. In the lower inner part of the fixing frame, from front to back, the following components are arranged sequentially... The device has a fixed connection with an applicator head, a rotating connection with an applicator roller, and a sliding connection with a tensioning roller. Both tensioning rollers have symmetrically arranged screw holes on their left and right sides. The two ends of the tensioning rollers are located in the left and right cavities, respectively. The top of the fixed frame has symmetrically arranged screw rods. Each screw rod has two sections of thread, with the upper and lower threads rotating in opposite directions. Both screw rods pass through the fixed frame and communicate with the left and right cavities, respectively. The upper threads of the two screw rods engage with the screw holes on the upper tensioning roller of the fixed frame, and the lower threads of the two screw rods engage with the screw holes on the lower tensioning roller of the fixed frame.

[0006] To further explain, the coating head has an internal cavity, and a slit is opened at the end of the coating head near the coating roller, which is connected to the cavity.

[0007] Further explanation: It also includes a movable rod, a rotating rod, and elastic elements. The upper rear end of the support is symmetrically provided with protrusions on the left and right sides. There are sliding grooves on the two protrusions. The movable rod is slidably connected to the two sliding grooves. Elastic elements are provided between the front left and right sides of the movable rod and the two sliding grooves. The rotating rod is rotatably connected to the movable rod.

[0008] To further explain, it also includes heating rods. The support has heating rods symmetrically arranged on the upper and lower sides, and the narrow gap between the two heating rods allows a whole sheet of silicone paper to pass through.

[0009] Further explanation: It also includes graduated cylinders. Graduated cylinders are symmetrically arranged on the top of the fixing frame. The graduated cylinders are made of transparent material and are marked with graduations. Two screws pass through the left and right graduated cylinders respectively. Each screw has an indicator mark inside the graduated cylinder.

[0010] To further explain, it also includes a paint tank and connecting pipes. The paint tank is located at the top center of the base, and a water pump is installed inside the paint tank. Connecting pipes are connected between the paint tank and the two paint heads.

[0011] The beneficial effects of this utility model are as follows: 1. By rotating the screw to control the movement of the two tensioning rollers in opposite directions, the tension of the front and rear ends of the silicone paper during the coating process can be precisely controlled to be consistent, thus preventing quality problems such as uneven coating caused by uneven tension.

[0012] 2. The design of two coating heads, one above the other, allows coating to be applied to both sides of the silicone paper, ensuring the consistency and uniformity of the coating. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0019] An automatic double-sided silicone paper coating machine, such as Figures 1-4 As shown, the device includes a base 1, a support 2, a placement cylinder 3, a coating roller 8, a coating head 9, a screw 10, a graduated cylinder 11, a take-up cylinder 12, a tensioning roller 15, and a fixing frame 16. The take-up cylinder 12 is connected to the front top of the base 1 and can be detached from the base 1. The take-up cylinder 12 facilitates removal after winding the silicone paper roll. The support 2 is located at the rear top of the base 1, and the placement cylinder 3 is connected to the top of the support 2. The placement cylinder 3 can be detached from the support 2 for placing the silicone paper roll on it. A fixing frame 16 is located in the middle of the top of the base 1. Cavities 17 are symmetrically arranged on the left and right sides inside the fixing frame 16. The upper inner part of the fixing frame 16 has a tensioning roller 15 slidably connected from front to back, a coating roller 8 rotatably connected, and a coating head 9 fixedly connected. The lower inner part of the fixing frame 16 has a coating head 9 fixedly connected from front to back, a coating roller 8 rotatably connected, and a tensioning roller 15 slidably connected. The coating head 9 has a cavity 901 inside. A slit 902 is opened at the end of the coating head 9 near the coating roller 8. The slit 902 is connected to the cavity 901. Screw holes are symmetrically arranged on both sides of the two tensioning rollers 15. The two ends of the two tensioning rollers 15 are located in the left and right cavities 17 respectively. Screws 10 are symmetrically arranged on the top of the fixing frame 16. Both screws 10 have two sets of threads, with the upper and lower threads rotating in opposite directions. Both screws 10 pass through the fixing frame 16 and communicate with the left and right cavities 17 respectively. The upper threads of the two screws 10 engage with the threaded holes on the upper tensioning rollers 15 of the fixing frame 16, and the lower threads of the two screws 10 engage with the threaded holes on the lower tensioning rollers 15 of the fixing frame 16. Since the upper and lower threads of the screws 10 rotate in opposite directions, rotating the screws 10 will cause the two tensioning rollers 15 on the screws 10 to move towards each other. The top of the fixing frame 16 is symmetrically equipped with graduated cylinders 11. Made of transparent material, the graduated cylinder 11 is marked with graduations. Two screws 10 pass through the left and right graduated cylinders 11 respectively. Each screw 10 has an indicator mark inside the graduated cylinder 11. Rotating the screws 10 on both sides causes the two tensioning rods 15 to move away from each other. Both ends of the two tensioning rods 15 slide within the cavity 17. The tensioning rod 15 at the bottom of the fixing frame 16 presses the silicone paper downwards, and the tensioning rod 15 at the top of the fixing frame 16 presses the silicone paper upwards. Rotating and adjusting the indicator marks on the two screws 10 makes the two indicator marks appear at the same graduation on the graduated cylinder 11. At this time, the tension at both ends of the silicone paper at the coating head 9 is consistent.

[0020] like Figure 1 and Figure 2 As shown, it also includes a moving roller 4, a rotating roller 5, an elastic element 6, and a heating roller 7. The upper rear end of the support 2 is symmetrically equipped with protrusions 201, each with a sliding groove. The moving roller 4 is slidably connected to the two sliding grooves. Elastic elements 6 are provided on both sides of the front end of the moving roller 4 between it and the two sliding grooves. The rotating roller 5 is rotatably connected to the moving roller 4. When the coating machine is working, the silicone paper slides over the rotating roller 5, causing the roller 5 to rotate. The elastic element 6 is in a compressed state and tends to relax. The elastic element 6 exerts a horizontal reaction force on the moving roller 4 and the rotating roller 5, with the direction of this reaction force being backward. This ensures that the silicone paper between the placement cylinder 3 and the heating roller 7 is always in a taut state. The support 2 is symmetrically equipped with heating rollers 7, and the narrow gap between the two heating rollers 7 allows a whole sheet of silicone paper to pass through. The silicone paper is heated as it passes over the two heating rollers 7, and the heated silicone paper makes it easier for the coating to adhere evenly to the silicone paper.

[0021] like Figure 1 As shown, it also includes a paint tank 13 and a connecting pipe 14. The paint tank 13 is located at the top center of the base 1. A water pump is installed inside the paint tank 13. The paint tank 13 is connected to the two coating heads 9 by connecting pipes 14. The paint is drawn out from the paint tank 13 by the water pump, reaches the cavity 901 through the connecting pipe 14, and flows out from the slit 902 on the coating head 9. The paint is then applied to the silicone paper.

[0022] When using this coating machine, place the silicone paper roll on the placement cylinder 3, unroll the silicone paper roll, and pull the silicone paper head around the rear end of the rotating roller 5, passing it downwards between the two heating rollers 7. During this process, the rotating roller 5 is subjected to pressure from the silicone paper, the moving roller 4 moves forward, and the elastic element 6 changes from its initial state to a compressed state, pulling the silicone paper head forward through the lower end of the tension roller 15 at the bottom of the fixed frame 16, to the space between the coating head 9 and the coating roller 8 at the bottom of the fixed frame 16, passing through the space between the coating head 9 and the coating roller 8, and pulling the silicone paper head backwards and upwards, passing the silicone paper head through the space between the coating head 9 and the coating roller 8 at the top of the fixed frame 16, pulling the silicone paper head so that it passes through the top of the tension roller 15 at the top of the fixed frame 16, and then pulling the silicone paper head forward to fix the silicone paper head in place. On the take-up drum 12, the screws 10 on the left and right sides are rotated, causing the two tensioning rollers 15 to move away from each other. The tensioning roller 15 at the bottom of the fixed frame 16 presses the silicone paper downward, and the tensioning roller 15 at the top of the fixed frame 16 presses the silicone paper upward. When the indicator marks on the two screws 10 are at the same scale on the scale cylinder 11, the tension at both ends of the silicone paper at the coating head 9 is consistent. When this coating machine is working, the placement cylinder 3 rotates to release the silicone paper, and the take-up drum 12 rotates to rewind the silicone paper. The silicone paper is heated when it passes the two heating rollers 7. When the silicone paper passes the coating head 9 at the bottom of the fixed frame 16, the paint is drawn out from the paint box 13, reaches the cavity 901 through the connecting pipe 14, flows out from the slit 902 on the coating head 9, and is coated onto the silicone paper. When the silicone paper passes the coating head 9 at the top of the fixed frame 16, the other side of the silicone paper is coated with paint.
