Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood-plastic flooring technology, specifically to an automated adhesive spraying device for PVC antistatic flooring. Background Technology
[0002] PVC antistatic flooring is a type of flooring made primarily of PVC resin using a special processing technique. It has permanent antistatic properties, resembles marble in appearance, and offers excellent decorative effects. It is suitable for locations requiring purification and antistatic properties, such as program-controlled machine rooms, computer rooms, and cleanrooms in the telecommunications and electronics industries.
[0003] During the production of PVC antistatic flooring, adhesive needs to be sprayed onto the back of the veneer for easier subsequent production and use. However, the veneer undergoes cutting and transportation before reaching the adhesive spraying process. During cutting, some debris may adhere to the veneer. If this debris is not cleaned before applying adhesive, it can cause the veneer to bulge after being attached to the backing board. These bulges are prone to rapid breakage during use. Similarly, damage is inevitable during the veneer production process. Without inspection and screening, these damaged products are considered defective and cannot be sold or used.

[0031] 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0033] Please see Figures 1-6 The automated adhesive spraying device for PVC antistatic flooring shown includes a conveyor 1, a dust removal and detection device 2, and an adhesive spraying device 3. The conveyor 1 is a roller conveyor, a mature and widely used conveyor in existing technology, and will not be described in detail here. The adhesive spraying device 3 is located in the middle of the conveyor 1 and is used to spray adhesive onto the surface. The dust removal and detection device 2 is located at the front end of the adhesive spraying device 3 and is used to remove dust and detect damage to the surface before the adhesive spraying process. The conveyor 1 is used to transport the surface to be sprayed with adhesive. The surface can be manually or automatically fed onto the conveyor 1. During the transport process, it first passes through the dust removal and detection device 2 for dust removal and damage detection, and then enters the adhesive spraying device 3 for adhesive spraying.
[0034] To ensure that the adhesive spraying space is not contaminated by external sources during the adhesive spraying process, an adhesive spraying chamber 301 is provided, and an automatic adhesive spraying device 302 for spraying adhesive onto the surface is installed in the adhesive spraying chamber. The adhesive spraying device 3 includes the adhesive spraying chamber 301 and two adhesive spraying components 302 installed inside the adhesive spraying chamber 301.
[0035] Specifically, the adhesive spraying assembly 302 includes a semi-enclosed belt module 3021, a connecting plate 3022, a long connecting rod 3023, a short connecting rod 3024, two open clamping blocks 3025, and an adhesive spraying head 3026. The connecting plate 3022 is connected to the sliding plate on the semi-enclosed belt module 3021. One end of the long connecting rod 3023 is connected to the connecting plate 3022, and the other end is connected to the adhesive spraying head 3026. One end of the short connecting rod 3024 is connected to the connecting plate 3022. The two open clamping blocks 3025 are symmetrically arranged vertically and lock the long connecting rod 3023 and the short connecting rod 3024. The adhesive spraying head 3026 is connected to an external adhesive supply device. Thus, when the semi-enclosed belt module 3021 operates, it can drive the adhesive spraying head 3026 to perform reciprocating linear motion, thereby achieving adhesive spraying on the surface. Meanwhile, to improve the efficiency of glue spraying, two glue spraying components 302 are set up. The two glue spraying components spray glue onto the surface at the same time, which improves the efficiency of glue spraying.
[0036] Specifically, the dust removal detection device 2 includes a dust removal hood 201, an electrostatic eliminator 202, a dust suction hood 203, an exhaust pipe 204, an exhaust fan 205, and a dust collection box 206. The dust removal hood 201 is mounted on the conveying device 1 and fixedly connected to the side of the spray booth 301. The electrostatic eliminator 202 and the dust suction hood 203 are both mounted on the dust removal hood 201, and the dust suction hood 203 is positioned between the electrostatic eliminator 202 and the spray booth 301. One end of the exhaust pipe 204 is connected to the interior of the dust suction hood 203, and the other end is connected to the air inlet of the exhaust fan 205. The air outlet 208 of the exhaust fan 205 is connected to the interior of the dust collection box 206 through a pipe. The dust hood 203 has a hollow internal structure, and a dust suction port 211 is provided on one end face of the dust hood 203 near the conveying device 1. The dust suction port 211 is elongated and multiple dust suction ports 211 are evenly arranged on the dust hood 203.
[0037] In this implementation plan, to ensure effective removal of dirt from the surface before applying adhesive and to detect and alert staff to any damage to the surface, a dust removal and detection device 2 is installed. The dust removal mechanism in the dust removal component 2 uses an exhaust fan 205 to draw air in, and then a dust suction hood removes debris and other impurities from the surface. To prevent fine dust from adhering to the surface due to static electricity, an anti-static rod 202 is installed at the front of the dust suction hood 203 to remove static electricity from debris, facilitating its removal. To detect surface damage, a linear CCD 210 is installed at the rear of the dust suction hood 203 to inspect the surface. The linear CCD 210 is connected to an external analysis and detection system.
[0038] When damage to the veneer is detected, an external alarm device alerts the staff to remove the damaged veneer and prevent it from being transferred to subsequent processes.
[0039] Specifically, the dust collection box 206 is equipped with a filter screen 207 and an air outlet 208. The air outlet 208 is also equipped with a dust filter screen 209. There are two air outlets 208, which are respectively located on both sides of the dust collection box 206, and each air outlet 208 is equipped with a dust filter screen 209.
[0040] In this embodiment, the filtration level of filter 207 is lower than that of dust filter 209. Debris on the surface is sucked away and enters the dust collection box 206 through the exhaust pipe 204. Larger debris is filtered out by filter 207, while finer debris further enters the lower part of the dust collection box 206 and is filtered by dust filter 209, preventing it from leaking into the factory air. An air outlet 208 is provided on the side of dust filter 209 to facilitate airflow.
[0041] Working Principle: First, the PVC antistatic flooring surface material is fed onto conveyor 1 via manual or automatic feeding. During conveying, it first passes through dust removal and damage detection device 2. The surface material first reaches the static eliminator 202, which removes static electricity from the debris. Then, exhaust fan 205 provides suction, and the dust on the surface is removed through exhaust pipe 204 and dust hood 203. The dust is sucked into dust hood 203 through suction port 211 and then enters dust collection box 206 through pipe. After entering dust collection box 206, larger debris is filtered out by filter screen 207, while smaller debris further enters the lower part of dust collection box 206 and is filtered by dust filter screen 209, preventing leakage into the factory air. The filtered air flows out from air outlet 208.
[0042] After dust removal, the laminated surface is moved to the linear CCD210 for inspection. When damage is detected, an external alarm system alerts the staff, prompting the damaged laminate to be removed to prevent it from proceeding to subsequent stages.
[0043] After inspection, the laminated surface enters the glue spraying chamber 301. The spraying chamber 301 effectively prevents airborne debris from entering the glue spraying area, avoiding secondary contamination of the laminated surface. Then, the semi-enclosed belt module 3021 on the glue spraying assembly 302 operates, driving the glue spraying head 3026 to spray glue onto the laminated surface. The simultaneous spraying of glue by two glue spraying assemblies 302 effectively improves glue spraying efficiency. After glue spraying, the laminated surface is conveyed to the next workstation via the conveyor device 1.
