Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically to a feeding structure for a coating and film covering device. Background Technology

[0002] Curtains are made of materials such as cloth, linen, gauze, aluminum sheets, wood shavings, and metal, and serve the functions of sun shading, heat insulation, and regulating indoor light. Fabric curtains are categorized by material, including cotton gauze, polyester fabric, cotton-polyester blends, cotton-linen blends, and non-woven fabrics. Different materials, textures, colors, and patterns combine to create curtains of various styles, complementing different interior designs. For curtains, light-blocking is a crucial function. In modern life, many people need to rest during the day or create a darker indoor environment for activities such as watching movies. Some curtain materials themselves have limited light-blocking capabilities; by applying a film, light can be effectively blocked, further improving the light-blocking performance.

[0003] The production process of durable flame-retardant polyester curtains consists of the following steps: purchasing fabric blanks, pretreatment, desizing, dyeing, color fixing, and lamination. In the color fixing stage before lamination, the fabric needs to be placed in a high-temperature chamber for high-temperature treatment before being taken out for preparation. The overall process cycle is long, which affects the lamination efficiency and further increases production and time costs. To address this issue, we propose a feeding structure for a coating and lamination device. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a feeding structure for a coating and film covering device includes an assembly table, on both sides of the assembly table surface are moving rollers, and in the middle of the assembly table is a rotating roller. A control component for driving the moving rollers downwards is provided on the surface of the assembly table. Assembly chambers are opened inside both the moving rollers and the rotating roller. Multiple sets of heating wires are installed in the assembly chambers. A closed platform is fixedly connected to the surface of the assembly table. Communicating windows are opened on both sides of the closed platform surface. The control component includes two assembly slots, which are opened on both sides of the assembly table surface. A fixed cylinder is fixedly connected to the top of the inner cavity of each assembly slot. A telescopic spring is built into the fixed cylinder. A moving seat is built into each assembly slot. A rotating rod is rotatably connected to the side of the moving seat away from the assembly table. The end of the rotating rod away from the moving seat extends out through the communicating window to the outside of the closed platform. The end of the rotating rod outside the closed platform is fixedly connected to the moving roller.

[0006] Preferably, the assembly table surface is provided with a fabric blank, which passes through the surfaces of multiple moving rollers and rotating rollers.

[0007] Preferably, the two moving rollers are symmetrically distributed along the axis of the assembly table, one end of the rotating roller is rotatably connected to the surface of the assembly table, and multiple grooves for contacting the fabric are provided around the moving roller and the rotating roller.

[0008] Preferably, the multiple sets of heating wires are evenly distributed along the length of the moving roller and the rotating roller.

[0009] Preferably, the connecting windows on both sides are symmetrically distributed along the axis of the closed platform, and the assembly slots on both sides are symmetrically distributed along the axis of the assembly platform.

[0010] Preferably, the motion seat is slidably connected to the wall of the assembly groove, and a connecting groove is provided at the end of the motion seat near the telescopic spring.

[0011] Preferably, one end of the telescopic spring is fixedly connected to the bottom of the inner cavity of the fixed cylinder, and the other end of the telescopic spring is fixedly connected to the bottom of the inner cavity of the connecting groove.

[0012] Preferably, guide plates are fixedly connected to both sides of the motion seat, and guide grooves matching the guide plates are opened on both sides of the assembly groove, and the guide plates are slidably connected to the groove walls of the guide grooves.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The excellent tensioning function of this utility model greatly improves the curing effect. The cooperation of the moving roller and the rotating roller, along with the function of the control component, ensures that the fabric is always in a taut state and in close contact with the roller surface. This close contact ensures that the fabric is heated evenly during the heating and curing process, reduces heat loss, improves energy utilization efficiency, and thus significantly improves the curing effect. The symmetrical distribution design ensures the stability of operation. This makes the fabric transport smooth and reliable. The excellent tensioning function improves the curing effect, and a good tension state is crucial for the feeding process. During the lamination feeding, the fabric needs to undergo a series of treatments. If the fabric cannot maintain a taut state, wrinkles and unevenness may occur, which will seriously affect the smoothness and accuracy of feeding. The tensioning function achieved through the cooperation of the moving roller and the rotating roller, as well as the control component, ensures that the fabric enters the subsequent processing stage smoothly during feeding, avoiding feeding jams or errors caused by uneven fabric.

[0014] During the coating process, the fabric blank needs to be cured. Uniform heating can make the curing process on the surface of the fabric blank more uniform and consistent, improving product quality. Good curing effect can also reduce subsequent processing problems caused by uneven curing, thereby improving the efficiency and quality of the entire production process. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-5As shown, this utility model provides a feeding structure for a coating and film covering device, including an assembly table 1. Motion rollers 301 are arranged on both sides of the assembly table 1, and a rotating roller 3 is installed in the middle of the assembly table 1. Fabric blanks 4 are arranged on the surface of the assembly table 1. The fabric blanks 4 pass through the surfaces of multiple motion rollers 301 and rotating roller 3. A control component 2 for driving the motion rollers 301 to move downward is arranged on the surface of the assembly table 1. The two motion rollers 301 are symmetrically distributed along the axis of the assembly table 1. One end of the rotating roller 3 is rotatably connected to the surface of the assembly table 1. Multiple grooves 302 for contacting the fabric blanks 4 are opened around the motion rollers 301 and rotating roller 3. Assembly chambers 303 are opened inside the motion rollers 301 and rotating roller 3. Multiple sets of heating wires 304 are installed in the assembly chambers 303. The multiple sets of heating wires 304 are evenly distributed along the length direction of the motion rollers 301 and rotating roller 3. Assembly chambers 303 are opened inside the motion rollers 301 and rotating roller 3. Multiple sets of heating wires 304 are installed in the chambers. Multiple sets of heating wires 304 are evenly distributed along the length of the moving roller 301 and the rotating roller 3. When the fabric 4 comes into contact with the moving roller 301 and the rotating roller 3, the heating wires 304 are energized and generate heat. The fabric 4 is evenly heated as it passes through the moving roller 301 and the rotating roller 3, and its surface is cured.

[0023] Furthermore, a closed platform 101 is fixedly connected to the surface of the assembly table 1. Connecting windows 102 are provided on both sides of the surface of the closed platform 101, symmetrically distributed along the axis of the closed platform 101. The control component 2 includes two assembly slots 201, located on both sides of the surface of the assembly table 1, symmetrically distributed along the axis of the assembly table 1. A fixed cylinder 202 is fixedly connected to the top of the inner cavity of the assembly slot 201, and a telescopic spring 203 is built into the fixed cylinder 202. A moving seat 204 is built into the assembly slot 201, slidably connected to the slot wall of the assembly slot 201. A connecting groove 205 is provided at one end of the moving seat 204 near the telescopic spring 203. One end is fixedly connected to the bottom of the inner cavity of the fixed cylinder 202, and the other end of the telescopic spring 203 is fixedly connected to the bottom of the inner cavity of the connecting groove 205. Guide plates 206 are fixedly connected to both sides of the motion seat 204. Guide grooves 207 matching the guide plates 206 are opened on both sides of the assembly groove 201. The guide plates 206 are slidably connected to the groove walls of the guide grooves 207. A rotating rod 208 is rotatably connected to the side of the motion seat 204 away from the assembly table 1. The end of the rotating rod 208 away from the motion seat 204 extends out from the connecting window 102 to the outside of the closed table 101. The end of the rotating rod 208 outside the closed table 101 is fixedly connected to the motion roller 301. The motion seat 204 in the control component 2 can slide up and down in the assembly groove 201. In the initial state, the telescopic spring 203 is in a natural or slightly compressed state, providing a certain support force to the motion seat 204. When the fabric 4 passes through the motion roller 301 and the rotating roller 3, if the fabric 4 is relatively loose, the motion roller 301 will be subjected to the tension of the fabric 4. Since the motion roller 301 is connected to the motion seat 204 through the rotating rod 208, the motion seat 204 will overcome the elastic force of the telescopic spring 203 and move downward. The guide plates 206 on both sides of the motion seat 204 slide in the guide grooves 207 on both sides of the assembly groove 201 to ensure the stability of the movement of the motion seat 204. The motion rollers 301 on both sides are symmetrically distributed along the axis of the assembly table 1 and move downward synchronously under the drive of the motion seat 204, so that the fabric 4 is tensioned and in close contact with the surfaces of the motion roller 301 and the rotating roller 3. Through the cooperation of the motion roller 301 and the rotating roller 3 and the action of the control component 2, the fabric 4 can always be kept in a tensioned state and in close contact with the surfaces of the motion roller 301 and the rotating roller 3. This ensures uniform heating of the fabric preform 4 during the curing process, improving the curing effect. Close contact also reduces heat loss and improves energy efficiency. Multiple sets of heating wires 304 inside the moving roller 301 and rotating roller 3 are evenly distributed along the length, enabling uniform heating of the fabric preform 4. This helps ensure uniform curing of the fabric preform 4 surface, improving curing quality. The design effectively improves the overall efficiency and quality of coating and film application, making it a very practical piece of equipment in industrial production.
