Description

Technical Field

[0001] The utility model relates to the technical field of recycling devices, in particular to a glue recycling device for a glue applicator. Background Art

[0002] In the prior art, glue applicators are widely used in various industrial production processes to evenly coat glue on the surface of products. However, as the glue is continuously used, the unutilized glue in the glue applicator needs to be recycled to reduce waste and save costs. Traditional glue recycling devices mainly rely on a simple pipeline system to recycle the unused glue into a storage tank. However, these recycling devices often face some technical problems in actual use.

[0003] Firstly, due to the viscosity and flow characteristics of the glue, glue residues are likely to adhere to the inner wall of the pipeline. These residues gradually accumulate over time, resulting in a reduction in the inner diameter of the pipeline, thereby hindering the normal flow of the glue. Eventually, these attachments may cause partial or complete blockage of the pipeline, seriously affecting the operating efficiency of the recycling device.

[0004] Secondly, during the recycling process, due to the poor flow of the glue, the traditional single main pipeline design often fails to effectively meet the recycling requirements for a large flow rate or high-viscosity glue, resulting in low recycling efficiency. In addition, the cleaning and maintenance of existing devices usually require manual intervention, which is complex and time-consuming, increasing the maintenance cost and downtime.

[0005] In view of this, the inventor has specifically designed a glue recycling device for a glue applicator, and this case is thus generated. Summary of the Utility Model

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0033] As Figure 1 shown, this embodiment provides a glue recovery device for a glue applicator, mainly including a recovery pipeline 1, an auxiliary pipeline 4, a collection tank assembly 3, a bracket 6, an anti-adhesion coating 5, a cleaning assembly 7, etc.

[0034] The core component of this glue recovery device for the glue applicator is the recovery pipeline 1. One end of it is connected to the glue outlet 9 of the glue applicator, and the other end is connected to the collection tank assembly 3 through a flange 8. To improve the fluidity during the glue recovery process, the recovery pipeline 1 is designed to be inclined, with the end close to the glue inlet 2 higher than the other end. This inclined design helps to utilize gravity to promote the smooth flow of the glue towards the collection tank assembly 3 and prevent the glue from staying in the pipeline.

[0035] AsFigure 4 As shown, a number of auxiliary pipes 4 connected in parallel to the recovery pipe 1 play a role in shunting. One end of the auxiliary pipe 4 is fixedly connected to the collection tank assembly 3. Through a reasonable shunting design, the flow pressure of the recovery pipe 1 is effectively reduced, ensuring good fluidity even during the recovery of high-flow or high-viscosity glue.

[0036] As Figure 3 shown, in order to prevent glue from adhering to the inner walls of the recovery pipe 1 and the auxiliary pipe 4 and causing blockage, a layer of anti-adhesion coating 5 is applied to the inner walls of the pipes. This coating can be a polytetrafluoroethylene (PTFE) coating or a fluororesin coating. The polytetrafluoroethylene coating has an extremely low coefficient of friction and excellent chemical resistance, effectively preventing the adhesion of various types of glue; the fluororesin coating has excellent chemical inertness and heat resistance, suitable for dealing with more demanding chemical environments.

[0037] As Figure 2 shown, the glue inlet 2 is located at the high end of the recovery pipe 1, designed as a detachable structure, and is equipped with a deflector 21. The deflector 21 is fixed to the glue inlet 2 by bolts or clips, and a filter screen 22 is also fixed below it. The filter screen 22 is used to filter out impurities in the glue, preventing the glue entering the pipe from containing solid particles or other substances that may block the pipe.

[0038] The main function of the deflector 21 is to guide the glue to smoothly enter the recovery pipe 1, reduce the impact when the glue flows in, avoid splashing and the generation of bubbles, thus ensuring the stability of the recovery process.

[0039] As Figure 5 shown, the collection tank assembly 3 includes a tank body 32. The top of the tank body 32 is connected to a tank cover 31 by a hinge. The tank cover 31 can seal the tank body 32 to prevent the glue from volatilizing or being contaminated when exposed to the air. An outlet 9 is provided at the bottom of the tank body 32, and the outlet 9 is connected to an automatic discharge valve, which can automatically discharge the recovered glue according to the liquid level in the tank body 32.

[0040] As Figure 1 shown, in order to stably support the recovery pipe 1, a bracket 6 is fixedly installed on the collection tank assembly 3. The height and position of the bracket 6 are precisely designed to ensure a firm and airtight connection between the recovery pipe 1 and the collection tank assembly 3.

[0041] The working principle of the cleaning component 7:

[0042] The cleaning component 7 is arranged inside the recycling pipeline 1 and is used to clean the glue that may remain on the inner wall of the pipeline. This component includes a push plate 72 mounted on a telescopic rod 71. The size of the push plate 72 matches the inner diameter of the recycling pipeline 1 and can slide along the inner wall of the pipeline. The telescopic rod 71 is driven manually, by a motor or a pneumatic device and can perform reciprocating motion inside the pipeline to push the glue adhering to the inner wall towards the collection tank.

[0043] When there is residual glue on the inner wall of the pipeline after collecting glue for a certain period of time, the cleaning component 7 is activated, and the push plate 72 pushes the glue along the inner wall of the pipeline to ensure that the inner wall of the pipeline remains clean, thereby preventing problems such as poor flow or blockage caused by glue residue.

[0044] Workflow:

[0045] During the operation of the glue applicator, the unused glue enters the recycling pipeline 1 through the glue inlet 2. Due to the inclined design of the pipeline and the function of the deflector 21, the glue can flow smoothly and be diverted to the auxiliary pipeline 4. During the flow process, the combined use of the anti - adhesion coating 5 and the cleaning component 7 ensures the cleanliness of the inner wall of the pipeline and the smooth flow of the glue.

[0046] When the glue reaches the collection tank component, through the glue outlet of the collection tank and the automatic discharge valve, the glue is introduced into the downstream storage or treatment equipment. The entire recycling process is efficient, stable, and reduces the dependence on manual maintenance.

[0047] This recycling device is designed with an automatic cleaning function and regularly operates the cleaning component to remove the residues on the inner wall of the pipeline. In addition, the glue inlet and the deflector are designed as detachable structures, which is convenient for daily cleaning and maintenance. Users can disassemble, clean, or replace the glue inlet, the deflector, and the filter screen according to needs, so as to keep the entire system clean and operating stably.

[0048] In summary, this practical information provides a glue recycling device for a glue applicator with a reasonable structure and perfect functions. Through the organic combination of multiple technical features, it effectively solves the problems of poor glue flow, pipeline blockage, and low recycling efficiency existing in the prior art. This device has high - efficiency glue recycling ability, reduces the need for manual maintenance, and is applicable to various industrial glue - applying application scenarios.

[0049] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above - mentioned manner. As long as various non - substantial improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
