Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric production equipment, specifically a printing composite nonwoven fabric coating production device. Background Technology

[0002] Composite nonwoven fabrics mainly include coated composite nonwoven fabrics, laser nonwoven fabrics, high-gloss nonwoven fabrics, and matte nonwoven fabrics. Coated composite nonwoven fabrics are made by coating the surface of the nonwoven fabric, which gives the nonwoven fabric the properties of being waterproof, blocking bacteria, or enhancing tensile strength.

[0003] Patent (CN119176451B) discloses a lamination production device for environmentally friendly composite nonwoven fabric used in thermal insulation bags, comprising: an unwinding assembly; a lamination assembly including a feeding device, a die head, and composite rollers, the composite rollers including a first clamping roller and a second clamping roller, the die head having two die openings, one of which outputs an adhesive layer to form a semi-finished composite film with the nonwoven fabric and thermal insulation film; a traction assembly for guiding the transmission path of the semi-finished composite film, making its input and output ends face opposite directions; and a winding assembly. Compared with the prior art, the lamination production device for environmentally friendly composite nonwoven fabric used in thermal insulation bags of the present invention guides the transmission path of the semi-finished composite film through the traction assembly, causing it to fold back and then be superimposed with the printed film and adhesive layer to form a finished composite film. The two lamination positions are located on the same straight line, thus requiring only a single set of composite rollers, and the die head has two die openings, requiring only a single detection system for detection, reducing the number of parts, lowering costs, and having a compact structure that reduces space occupation.

[0004] The composite nonwoven fabric coating production device in the above patent performs coating treatment on the nonwoven fabric through a die head and a die opening. However, the die head is located at the top center of the die opening. The material entering the die opening from the die head first enters the center of the die opening and then moves to both sides of the die opening, which easily leads to poor uniformity of material output from the die opening, and thus poor uniformity of coating on the surface of the nonwoven fabric. Utility Model Content

[0005] The purpose of this invention is to provide a printing composite nonwoven fabric coating production device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a printing composite nonwoven fabric coating production device, including a frame, a storage box movably connected to the inner side of the frame, a feed inlet vertically provided at the top center of the storage box, and discharge outlets symmetrically provided on both sides of the bottom of the storage box, a rotatably connected picking roller provided inside the discharge outlet of the storage box, a coating roller rotatably connected below the picking roller at the bottom of the storage box, the outer wall of the coating roller being rolledly connected to the outer wall of the picking roller, and a rotatably connected support roller provided below the coating roller on the inner side of the frame, the picking roller and the coating roller being parallel to each other.

[0007] Furthermore, the material taking roller is inclined above the coating roller, and the two material taking rollers are located between the two coating rollers.

[0008] Furthermore, the outer wall of the storage box is symmetrically provided with sliders on both sides, the inner wall of the frame is vertically provided with a guide rail frame that matches the sliders, and the inner wall of the frame is vertically provided with a cylinder above the guide rail frame, the output end of the cylinder being fixedly connected to the slider.

[0009] Furthermore, the inner wall of the storage box is provided with electric heating wires, which are located on both sides of the inner wall of the storage box.

[0010] Furthermore, the inner wall of the storage tank is horizontally provided with a stirring shaft, the stirring shaft is parallel to the material taking roller, and the outer wall of the stirring shaft is provided with a plurality of first stirring rods and second stirring rods.

[0011] Furthermore, the first stirring rod has a first turbine blade rotatably connected to the end away from the stirring shaft, and the second stirring rod has a second turbine blade rotatably connected to the end away from the stirring shaft.

[0012] Furthermore, the first stirring rod and the second stirring rod are staggered on both sides of the outer wall of the stirring shaft, and the length of the first stirring rod is less than the length of the second stirring rod.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. This utility model comprises a frame, a storage bin, a feed inlet, a take-up roller, a coating roller, and a support roller. A portion of the take-up roller's surface is located inside the storage bin, directly contacting the coating material, while the other portion is located outside the storage bin. During the rotation of the take-up roller, its surface is coated with coating material, and simultaneously, it rolls against the coating roller's surface. The coating roller's rotation transfers the coating material from the take-up roller to the coating roller's surface. This material is then evenly distributed across the coating roller's surface through the storage bin, the feed inlet, and the take-up roller. The support roller provides rolling support for the nonwoven fabric, and the coating roller performs roll-pressing and laminating treatment on the nonwoven fabric above the support roller. The combined operation of these two sets of coating rollers effectively improves the roll-pressing and laminating effect on the composite nonwoven fabric and ensures the uniformity of the coating treatment on the composite nonwoven fabric surface.

[0015] 2. In this utility model, the electric heating wire can effectively heat the material inside the storage tank. The stirring shaft drives the first stirring rod and the second stirring rod to stir the coating material inside the storage tank. The first turbine blade at the end of the first stirring rod moves in a circular motion around the stirring shaft along with the first stirring rod, and the first turbine blade rotates on its own axis at the end of the first stirring rod, which can further improve the stirring effect of the coating material inside the storage tank and effectively improve the heating uniformity and stability of the coating material. The second turbine blade at the end of the second stirring rod moves in a circular motion around the stirring shaft along with the second stirring rod, and the second turbine blade rotates on its own axis at the end of the second stirring rod, which can further improve the stirring effect of the coating material inside the storage tank and effectively improve the heating uniformity and stability of the coating material.

[0022] 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.

[0023] Please see Figures 1-4This utility model provides a technical solution: a printing composite nonwoven fabric coating production device, including a frame 1, a storage box 2 movably connected to the inner side of the frame 1, a vertically arranged inlet 201 at the top center of the storage box 2, and symmetrically arranged outlets on both sides of the bottom of the storage box 2. A rotatably connected picking roller 202 is arranged inside the outlet of the storage box 2, and a rotatably connected coating roller 203 is arranged at the bottom of the storage box 2 below the picking roller 202. The outer wall of the coating roller 203 is rolledly connected to the outer wall of the picking roller 202. A rotatably connected support roller 2 is arranged inside the frame 1 below the coating roller 203. 04. The feeding roller 202 and the coating roller 203 are parallel to each other; the inner wall of the storage box 2 is provided with an electric heating wire, which is located on both sides of the inner wall of the storage box 2; the inner wall of the storage box 2 is horizontally provided with a stirring shaft 208, which is parallel to the feeding roller 202; the outer wall of the stirring shaft 208 is provided with a plurality of first stirring rods 209 and second stirring rods 210; the first stirring rod 209 is provided with a first turbine blade 211 rotatably connected to the end away from the stirring shaft 208, and the second stirring rod 210 is provided with a second turbine blade 212 rotatably connected to the end away from the stirring shaft 208.

[0024] In one embodiment, the feeding roller 202 is inclined above the coating roller 203, and the two feeding rollers 202 are located between the two coating rollers 203, so that the two coating rollers 203 can perform rolling coating treatment on the surface of the nonwoven fabric outside the feeding roller 202, ensuring that the heated and melted material is evenly adhered and pressed onto the surface of the nonwoven fabric. Even if the material on the feeding roller 202 accidentally drips onto the surface of the nonwoven fabric, the nonwoven fabric still needs to be coated by the coating roller 203, which can effectively avoid the presence of untreated dripping material on the surface of the nonwoven fabric, thereby improving the coating treatment effect of the nonwoven fabric.

[0025] In one embodiment, sliders 205 are symmetrically arranged on both sides of the outer wall of the storage box 2, and a guide rail frame 206 matching the sliders 205 is vertically arranged on the inner wall of the frame 1. A cylinder 207 is vertically arranged above the guide rail frame 206 on the inner wall of the frame 1. The output end of the cylinder 207 is fixedly connected to the slider 205. The slider 205 provides vertical guidance to the outside of the storage box 2, and the guide rail frame 206 guides the slider 205, which can effectively ensure the safety and stability of the slider 205's lifting and lowering movement. The extension and retraction of the cylinder 207 can effectively drive the slider 205 to lift and lower, thereby driving the storage box 2 to lift and lower, thus realizing the lifting and lowering adjustment of the coating roller 203, which is convenient for coating composite nonwoven fabrics of different thicknesses.

[0026] In one embodiment, the first stirring rod 209 and the second stirring rod 210 are staggered on both sides of the outer wall of the stirring shaft 208, and the length of the first stirring rod 209 is less than the length of the second stirring rod 210. The first stirring rod 209 and the second stirring rod 210 rotate on the outside of the stirring shaft 208. The first turbine blade 211 and the second turbine blade 212 on the first stirring rod 209 and the second stirring rod 210 can effectively stir the material inside the storage tank 2 at different positions, which can effectively improve the stirring effect of the molten material inside the storage tank 2, making the molten material inside the storage tank 2 more evenly distributed and the heat distribution more even, which can effectively ensure the stability of the molten material and ensure the coating effect of the nonwoven fabric.

[0027] The working principle of this utility model:

[0028] Refer to the instruction manual appendix Figures 1-4 This utility model comprises a frame 1, a storage bin 2, a feed inlet 201, a take-up roller 202, a coating roller 203, and a support roller 204. The frame 1 supports the storage bin 2. The feed inlet 201 at the top of the storage bin 2 is used to transport the coating material into the storage bin 2. The material inside the storage bin 2 moves towards the discharge outlet. The take-up roller 202 is located inside the discharge outlet and blocks the discharge outlet. The coating material can only be transported outwards after passing through the take-up roller 202. Part of the surface of the take-up roller 202 is located inside the storage bin 2 and is in direct contact with the coating material, while another part of the surface of the take-up roller 202 is located outside the storage bin 2. During the rotation of the take-up roller 202, the surface of the take-up roller 202... The rotational motion causes the surface of the feeding roller 202 to be covered with coating material. At the same time, the feeding roller 202 rolls and contacts the surface of the coating roller 203 as it rotates. The coating roller 203 rotates, and the coating material on the surface of the feeding roller 202 is transferred to the surface of the coating roller 203. The coating material is transferred through the storage box 2, the discharge port and the feeding roller 202, so that the coating material is evenly distributed on the surface of the coating roller 203. The support roller 204 provides rolling support for the nonwoven fabric. The coating roller 203 performs roll-press composite coating treatment on the nonwoven fabric above the support roller 204. The coordinated work of the two sets of coating rollers 203 can effectively improve the roll-press composite coating treatment effect on the composite nonwoven fabric and effectively ensure the uniformity of the coating treatment on the surface of the composite nonwoven fabric.

[0029] The electric heating wire inside the storage tank 2 can effectively heat the material inside the storage tank 2. The stirring shaft 208 rotates inside the storage tank 2, driving the first stirring rod 209 and the second stirring rod 210 to stir the coating material inside the storage tank 2. The first turbine blade 211 at the end of the first stirring rod 209 moves in a circular motion around the stirring shaft 208 along with the first stirring rod 209, and the first turbine blade 211 rotates on its own axis at the end of the first stirring rod 209, which can further improve the stirring of the coating material inside the storage tank 2. The second turbine blade 212 at the end of the second stirring rod 210 stirs the coating material inside the storage tank 2 along with the second stirring rod 210. The second turbine blade 212 at the end of the second stirring rod 210 moves in a circular motion around the stirring shaft 208 along with the second stirring rod 210, and the end of the second stirring rod 210 rotates on its own axis, which can further improve the stirring effect of the coating material inside the storage tank 2, and effectively improve the heating uniformity and stability of the coating material.

[0030] The rotation of the stirring shaft 208, the coating roller 203, and the material taking roller 202 can all be driven by motors, or other rotation drives can be used.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for 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.
