Description

Technical Field

[0001] The utility model relates to the technical field of fabric coating, and more specifically, it relates to a coating machine for fabric production. Background Art

[0002] In textile processing, textile coating adhesives are often used to achieve various functions of textiles. By using a coating machine, one or more thin films are formed on the surface of the textile fabric to achieve specific functions of the fabric. During the coating process, it may be necessary to replace the glue of the thin film, and the mixing of multiple glues easily reduces the product quality.

[0003] In view of the above problems, a fabric coating device disclosed in a Chinese patent with the publication number CN216074335U includes a frame, an upper glue wheel, a lower pressing wheel and a scraper. A glue storage tank is arranged below the frame; the upper glue wheel is rotatably connected to the frame, and a part of the upper glue wheel is located in the glue storage tank; the lower pressing wheel is located above the upper glue wheel and is arranged parallel to the upper glue wheel, and the lower pressing wheel is rotatably connected to the frame; the scraper is located on one side where the upper glue wheel rotates out of the glue storage tank. Along the rotation direction of the upper glue wheel, the scraper is located between the upper glue wheel and the lower pressing wheel, and the scraper is rotatably connected to the inner wall of the glue storage tank; wherein, the scraper rotates so that there is a gap between the scraper and the lower pressing wheel, or the end of the scraper abuts against the surface of the upper glue wheel.

[0004] The above solution makes the scraper fit the surface of the upper glue wheel by rotating the scraper, which is more convenient for cleaning the glue on the upper glue wheel and facilitating the coating of the next thin film. However, in the above solution, only one side of the fabric can be coated by the upper glue wheel, and the fabric cannot be coated on both sides, which is inconvenient.

[0005] Therefore, a solution needs to be proposed to solve this problem. Summary of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a coating machine for fabric production, which drives a pressing roller and an upper glue roller to move through a driving mechanism, and flips the fabric after the two are moved away to achieve double-sided coating.

[0007] The above technical object of the present utility model is achieved through the following technical solutions: A coating machine for fabric production includes a base and two vertical plates slidably connected to the upper end surface of the base. A driving device for driving the two vertical plates to move is arranged on the base. Mounting frames are rotatably connected to the sides of the two vertical plates close to each other. A unwinding roller and a winding roller are respectively rotatably connected to the two mounting frames. A support is slidably connected to the upper end surface of the base. A driving mechanism for driving the support to move is arranged on the upper end surface of the base. A glue storage tank is fixedly connected to the side wall of the support. An upper glue roller rotatably connected to the support is arranged above the glue storage tank. A pressing roller rotatably connected to the support is arranged above the upper glue roller.

[0008] By adopting the above technical solutions, under normal circumstances, the fabric passes through the glue application channel between the pressing roller and the upper glue roller. At this time, the unwinding roller and the winding roller can normally unwind and wind the fabric. The upper glue roller applies glue to the lower side of the fabric. When one side of the fabric is coated, the driving mechanism can be used to drive the support to move, so that the support drives the upper glue roller and the pressing roller away from the fabric, and the fabric can be removed from between the upper glue roller and the pressing roller. Then, by rotating the mounting frames on both sides, the unwinding roller and the winding roller are driven to flip, and then the support is moved back to its original position. In this way, the upper glue roller can apply glue to the other side of the flipped fabric, realizing double-sided coating processing of the fabric. And by moving the two vertical plates to adjust the distance between the unwinding roller and the winding roller, the tension of the fabric is adjusted to meet the coating requirements of more different fabrics.

[0009] The present utility model is further provided as follows: The driving mechanism includes a rack fixedly connected to the side wall of the support. A support frame is fixedly connected to the upper end surface of the base. A gear rotatably connected to the support is arranged on the support. The gear meshes with the teeth on the rack. A driving member for driving the gear to rotate is arranged on the support.

[0010] By adopting the above technical solutions, when it is necessary to drive the support to move, the driving member is used to drive the gear to rotate. The forward and reverse rotation of the gear can drive the rack to move reciprocally. The rack can drive the vertical plate and the upper glue roller and the pressing roller installed on the vertical plate to move, so that when the fabric needs to be flipped, the upper glue roller can be moved away to make room for flipping, and when glue needs to be applied, the upper glue roller is moved back to its original position. The operation is convenient. After moving to the appropriate position, the driving member is turned off to stop rotating the gear.

[0011] The present utility model is further provided as follows: The driving device includes a cavity arranged inside the base. A bidirectional lead screw is rotatably connected inside the cavity. A motor for driving the lead screw to rotate is installed on the base. Nut seats are sleeved on the left-handed thread section and the right-handed thread section of the lead screw. The two nut seats are respectively fixedly connected to the two vertical plates. Moving grooves for the nut seats to extend out and move are arranged on the inner wall of the cavity.

[0012] By adopting the above technical solution, when it is necessary to adjust the positions of the vertical plates on both sides, the motor drives the bidirectional lead screw to rotate. The forward and reverse rotations of the bidirectional lead screw can drive the nut seats on both sides to approach or move away from each other. The nut seats on both sides can drive the vertical plates connected to them to move, and the mounting brackets and rollers mounted on the vertical plates will also move together. The distance between the unwinding roller and the winding roller will change, and the tension of fabrics with different elasticities can be adjusted to meet the usage requirements in more situations.

[0013] The present utility model is further configured as: a groove is formed on the side wall of the bracket, a slider slidably connected thereto is arranged in the groove, the pressing roller is rotatably connected to the slider, a push rod is fixedly connected to the bracket, and the output end of the push rod is fixedly connected to the slider.

[0014] By adopting the above technical solution, when the thickness of the fabric is different, the telescopic push rod can be used to drive the slider to move along the groove, so that the slider drives the height of the pressing roller to be adjusted. The pressing roller can drive the distance between the fabric and the coating roller to change, enabling the fabric to adjust the coating thickness according to its own thickness situation to meet the usage requirements in more situations. The downward pressure of the pressing roller can also adjust the tension of the fabric.

[0015] The present utility model is further configured as: a limiting block is fixedly connected to the side wall of the nut seat, and a limiting groove for the limiting block to insert and move is arranged on the inner wall of the cavity.

[0016] By adopting the above technical solution, during the movement of the nut seat along with the rotation of the bidirectional lead screw, the limiting block will insert into the limiting groove and move, making the nut seat more stable during the movement.

[0017] The present utility model is further configured as: a limiting rod is fixedly connected to the upper end surface of the base, and a through hole for the limiting rod to pass through is formed on the bracket.

[0018] By adopting the above technical solution, when the bracket moves together with the rack, the bracket will move along the limiting rod, making the bracket more stable during the movement.

[0019] In summary, the present utility model has the following beneficial effects:

[0020] The present utility model drives the pressing roller and the coating roller to move through the setting of the driving mechanism, and flips the fabric after the two are moved away to achieve double-sided coating. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Under normal circumstances, the fabric will pass through the gluing channel between the pressure roller 9 and the gluing roller 8. At this time, the unwinding roller 4 and the winding roller 5 can unwind and wind the fabric normally, and the gluing roller 8 glues the side of the fabric facing downward. After the coating on one side of the fabric is completed, the bracket 6 can be driven to move by the driving mechanism, so that the bracket 6 drives the gluing roller 8 and the pressure roller 9 away from the fabric, and the fabric can be moved out from between the gluing roller 8 and the pressure roller 9, and then the unwinding roller 4 and the winding roller 5 are driven to flip by rotating the mounting frames 3 on both sides, and then the bracket 6 is moved back to its original position, so that the gluing roller 8 can apply glue to the other side of the flipped fabric, thereby realizing double-sided coating processing of the fabric, and the spacing between the unwinding roller 4 and the winding roller 5 is adjusted by moving the vertical plates 2 on both sides to realize the adjustment of the fabric tension force, thereby meeting the coating requirements of more different fabrics.
