Description

Technical Field

[0001] This utility model belongs to the technical field of mesh fabric production equipment, and in particular relates to a paste application device for mesh fabric processing. Background Technology

[0002] Mesh-reinforced fabric, a high-strength, tear-resistant composite material, is widely used in tents, inflatable toys, waterproof rolls, and other fields. In the production and processing of mesh-reinforced fabric, the adhesive application process is crucial in determining the product's bonding strength and appearance quality. Its core requirement is to ensure the adhesive is evenly applied to the mesh surface while avoiding adhesive waste and equipment blockage.

[0003] Currently, most commonly used mesh fabric coating devices in the industry adopt a single-end feeding and bottom discharge structure design. That is, the paste enters the pipe hole inside the shell from the feeding pipe at one end of the device and drips directly onto the mesh fabric surface through the fixed discharge structure at the bottom. However, in practical applications, this type of device has the following defects: poor paste flow, easy residue and clumping, inconvenient maintenance, and insufficient uniformity of paste application. In this system, due to the single-end feeding, the paste flows unidirectionally within the tube. Areas far from the feeding end are prone to paste stagnation due to slower flow rates. Especially when the paste has a certain viscosity, the residual paste gradually clumps, affecting the uniformity of subsequent paste application and requiring frequent shutdowns for cleaning, thus reducing production efficiency. Furthermore, the existing paste application mechanism is mostly fixedly connected to the housing. When the discharge nozzle becomes clogged, worn, or requires replacement with a different discharge structure, the entire housing must be disassembled, which is complex and time-consuming, further increasing production downtime. At the same time, the discharge nozzles are usually arranged in a straight line, and the inlet connecting to the tube is designed at a right angle. When the paste flows through the inlet, it is easy to form eddies or flow interruptions, resulting in unstable paste output from some discharge nozzles. Ultimately, this leads to uneven thickness on the mesh surface, affecting product quality.

[0004] Therefore, developing a paste-applying device for mesh fabric processing that can solve the problem of paste residue, is easy to maintain, and provides uniform paste application has become an urgent technical problem to be solved in the industry. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a paste application device for processing mesh fabric. By optimizing the overall structure of the device and the design of key components, the goal of efficient paste circulation, convenient maintenance of the paste application mechanism, and uniform paste application to the mesh fabric is achieved.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a strip-shaped shell and a connector on its top for connecting to a frame. The strip-shaped shell has a pipe hole inside. Sealing plates are installed at both ends of the strip-shaped shell. A feed pipe is installed on the sealing plate at one end and is connected to the pipe hole. A discharge pipe is installed on the sealing plate at the other end of the strip-shaped shell and is connected to the pipe hole. A paste-applying mechanism is movably installed at the bottom of the strip-shaped shell. The paste in the pipe hole drips from the paste-applying mechanism onto the surface of the mesh fabric.

[0007] Furthermore, the inlet and outlet pipes are both located on the axis of the pipe hole, and the inlet and outlet pipes are connected to the two sealing plates.

[0008] Furthermore, the top of the paste-applying mechanism is an arc surface with the same diameter as the tube hole, and is spliced ​​together to form a cylindrical through hole.

[0009] Furthermore, the bottom of the paste-applying mechanism is fixedly provided with several discharge nozzles, which are connected to the tube hole through a narrow-diameter circular hole. The top edge of the narrow-diameter circular hole is designed with a chamfered angle, and the several discharge nozzles are arranged in a wavy line at the bottom of the paste-applying mechanism.

[0010] Furthermore, limiting slides are fixedly provided on both sides of the paste-applying mechanism, and the strip-shaped housing has a sliding groove at the limiting slide. The limiting slide is inserted into the sliding groove from one end and then slidably connected.

[0011] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, by setting inlet pipes and outlet pipes at both ends of the strip shell, a paste flow path of inlet-circulation-outlet is formed. The paste flows in the pipe hole in a full-section state, avoiding the stagnation problem caused by unidirectional flow. At the same time, the top of the paste feeding mechanism is spliced ​​with the pipe hole to form a cylindrical through hole, eliminating the irregular gap at the bottom of the pipe hole, further reducing paste residue, significantly reducing the frequency of equipment cleaning, and improving production continuity. 2. In this utility model, the paste-feeding mechanism is slidably connected to the slide groove of the strip shell through a limiting slide bar. When it is necessary to clean the discharge nozzle, replace the paste-feeding mechanism, or adjust the discharge specifications, there is no need to disassemble the connection between the strip shell and the frame. The operation can be completed simply by pulling out the paste-feeding mechanism along the slide groove, which greatly shortens the maintenance time and reduces production interruption. 3. In this utility model, the discharge nozzle adopts a wavy linear arrangement, which can more comprehensively cover the surface of the mesh fabric compared with the conventional straight linear arrangement, avoiding the phenomenon of paste leakage at the edge or splice of the mesh fabric; at the same time, the chamfered design at the top of the fine diameter round hole reduces the resistance of paste flow, avoids the instability of paste output caused by eddies or flow interruption, and keeps the paste thickness deviation on the mesh fabric surface within a very small range, significantly improving the stability of product quality. 4. In this utility model, the device has a compact overall structure. The connecting parts can be adapted to different specifications of frames by adjusting the position of the bolts. The pasting mechanism can be changed to different models of discharge nozzle density according to the width and thickness of the mesh, which is suitable for processing various specifications of mesh fabric and reduces equipment investment costs.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Combination Figures 1 to 5 The device shown is a paste-applying device for processing mesh fabric, including a strip-shaped housing 1 and a connector 2 at its top for connecting to a frame. The strip-shaped housing 1 has a pipe hole 11 inside. Both ends of the strip-shaped housing 1 are equipped with sealing plates 3. A feed pipe 4 is installed on the sealing plate 3 at one end and is connected to the pipe hole 11. A discharge pipe 5 is installed on the sealing plate 3 at the other end of the strip-shaped housing 1 and is connected to the pipe hole 11. A paste-applying mechanism 6 is movably installed at the bottom of the strip-shaped housing 1. The paste in the pipe hole 11 drips from the paste-applying mechanism 6 onto the surface of the mesh fabric.

[0016] The inlet of the feed pipe 4 and the outlet of the discharge pipe 5 are both located on the axis of the pipe hole 11, and the feed pipe 4 and the discharge pipe 5 are connected to the two sealing plates 3.

[0017] The top of the paste-applying mechanism 6 is an arc surface with the same diameter as the tube hole 11, and is spliced ​​together to form a cylindrical through hole.

[0018] The bottom of the paste-applying mechanism 6 is fixed with several discharge nozzles 61, which are connected to the tube hole 11 through a narrow diameter round hole 62. The top edge of the narrow diameter round hole 62 is designed with a chamfered angle, and the discharge nozzles 61 are arranged in a wavy line at the bottom of the paste-applying mechanism 6.

[0019] Both sides of the paste-applying mechanism 6 are fixedly provided with limiting slide bars 63. The strip-shaped housing 1 has a slide groove 12 at the limiting slide bar 63. The limiting slide bar 63 is inserted into the slide groove 12 from one end and then slid and connected.

[0020] Working principle: During use, the strip-shaped housing 1 is fixed to the frame by the bolts of the connector 2. The position of the bolts is adjusted so that the distance between the discharge nozzle 61 of the paste feeding mechanism 6 and the lower mesh conveying line is maintained at 5-10mm. The feed pipe 4 is connected to the outlet of the paste conveying pump, and the discharge pipe 5 is connected to the inlet of the paste recovery tank to complete the pipeline installation. Start the paste conveying pump. The paste enters the pipe hole 11 of the strip shell 1 through the feed pipe 4. Since the pipe hole 11 and the top of the paste feeding mechanism 6 are spliced ​​to form a complete cylindrical channel, the paste flows evenly along the entire length of the pipe hole 11. During the flow, the paste enters the discharge nozzle 61 through the narrow diameter hole 62 of the paste feeding mechanism 6 and drips onto the surface of the mesh fabric being conveyed at a uniform speed below under the action of gravity. The paste that does not flow out from the narrow diameter hole 62 flows into the recycling tank through the discharge pipe 5 to achieve recycling and avoid waste. When it is necessary to clean the discharge nozzle 61, turn off the paste conveying pump, disconnect the feed pipe 4 from the conveying pump, and pull out the paste feeding mechanism 6 along the slide 12 to directly clean the residual paste in the discharge nozzle 61 and the fine diameter round hole 62. If it is necessary to adjust the density of the discharge nozzle 61 and replace the paste feeding mechanism 6 of different specifications, simply pull out the old mechanism and insert the new mechanism. The whole process does not require disassembling the strip shell 1, making the operation convenient.
