Description

[0002] Gum has important application value in industrial manufacturing, and is widely used in the preparation of automobile tires, seals, electronic component protection layer and protective equipment. However, due to its high viscosity and poor flowability, it is prone to sticking and agglomeration, especially during transportation and storage, which may cause blockage. Effective measures need to be taken to ensure continuous supply and stability of the gum to improve production efficiency and product quality.

[0003] In the existing gum conveying technology, the gum has high viscosity, which is prone to sticking and agglomeration during transportation, resulting in blockage in the pipeline or conveying equipment. Since the gum aggregation blocks the conveying channel, manual dredging is usually required to maintain normal transportation, but even with manual intervention, about two blockages occur every day, and each manual cleaning process takes about 0.5 hours, resulting in discontinuous gum supply, which affects the quality stability of semi-finished products in production. In addition, frequent blockage and cleaning disrupt the production process, affecting overall production efficiency and failing to meet the production requirements for continuity and high efficiency.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 and Figure 2 As shown, an auxiliary glue breaking device for a glue supply extruder includes an extruder 1, a screw 2, a connecting rod 3, a scraping gear 4 and a photoelectric switch 5. The screw 2 is set on the extruder 1 to provide transmission during the glue supply process; the connecting rod 3 is connected between the frame of the extruder 1 and the screw 2 to stabilize the device structure. The scraping gear 4 is installed on the connecting rod 3. The scraping gear (4) is used to apply external force to the rubber blocks being transported to break up the rubber blocks and speed up the transportation. It has an outer diameter of 160mm, an inner diameter of 110mm, and has 112.5-degree oblique triangular teeth to assist in scraping off excess glue to prevent adhesion and accumulation. The photoelectric switch 5 is fixed on the frame of the extruder 1 to detect the passage of rubber blocks near the glue outlet.

[0024] This embodiment utilizes the rotation of the scraping gear 4 to bring its oblique triangular teeth into contact with the surface of the rubber block, creating a scraping effect that effectively breaks up the sticking of the rubber block, preventing blockage and accumulation of the rubber material 6. Furthermore, the detection function of the photoelectric switch 5 provides timely feedback on the position of the rubber block, facilitating the control and adjustment of the speed and amount of rubber dispensing during the extrusion process, thereby improving work efficiency. This device effectively breaks up the rubber block, reduces adhesion issues during the extrusion process, and ensures a continuous and stable supply of rubber material 6. Furthermore, the introduction of the photoelectric switch 5 enhances the intelligence level of the device and facilitates precise control of the colloid transmission path and flow rate.

[0025] The scraper gear 4 can be made of a more wear-resistant material, such as stainless steel or ceramic, to extend its service life. The connection between the connecting rod 3 and the screw 2 can also be welded instead of threaded, enhancing the stability of the fixation. Furthermore, the position of the photoelectric switch 5 can be adjusted near the glue outlet as needed to accommodate glue blocks of varying sizes.

[0026] The distance between the scraper gear 4 and the glue outlet is set to 80mm. Maintaining a fixed distance of 80mm between the scraper gear 4 and the glue outlet enables the scraper gear 4 to effectively scrape away glue lumps while avoiding wear or blockage caused by close contact. This design ensures that glue lumps are properly broken up before they approach the glue outlet, ensuring smooth transmission of downstream rubber material 6. By setting a distance of 80mm, while ensuring effective glue breaking, material accumulation between the scraper gear and the glue outlet is reduced, thus extending the service life of the equipment.

[0027] The distance between the scraping gear 4 and the glue outlet can be adjusted to between 70-90 mm according to the characteristics of different glue blocks, so as to better adapt to glue blocks of different sizes or viscosities.

[0028] The scraper gear 4 is composed of two symmetrical semi-circular ring structures, which are fixed to the outside of the screw 2 and the connecting rod 3 of the extruder 1 frame by screws. The structure adopts a symmetrical semi-circular ring design and is fixed by screws, which is convenient for disassembly and cleaning. This design can ensure that the scraper gear 4 runs stably on the screw 2 and can be quickly replaced when necessary to ensure the efficient operation of the system. This design improves the maintenance convenience of the equipment and facilitates operators to quickly repair or replace it in daily use, reducing downtime and improving production efficiency.

[0029] Photoelectric switch 5 is mounted on the extruder 1 frame near the glue outlet and is used to detect the transfer position and status of the rubber block in real time. Its installation near the glue outlet allows for accurate detection of the movement of the rubber block. Upon detecting the passage of a rubber block, photoelectric switch 5 sends a signal to control the extruder's feed speed or the output of rubber material 6, achieving automated control. This configuration, by detecting the position of the rubber block in real time, enables more accurate supply of rubber material 6, avoids equipment failures caused by block block blockage or displacement, and thus improves equipment operational stability and production efficiency.

[0030] The position of the photoelectric switch can be adjusted within the range of 20-100mm from the glue outlet according to different needs to adapt to the transmission requirements of glue blocks of different sizes or shapes.

[0031] The distance between the glue scraping gear 4 and the glue outlet is 80mm, which is smaller than the width of the glue block, the linear speed of the outer edge of the glue scraping gear 4 is much higher than that of the glue block, so that the glue block is accelerated and dispersed, and the glue block is prevented from gathering; the installation position is slightly smaller than the width of the glue block, so that the glue block is prevented from being squeezed, and when the glue block loses power due to deceleration, the glue block is provided with external force in time, so that the glue block is continuously dispersed; since the distance between the glue scraping gear 4 and the glue outlet is smaller than the width of the glue block, the inclined triangular teeth of the glue scraping gear 4 can scrape the surface of the glue block more comprehensively, so that the glue block is fully broken before entering the glue outlet, which is helpful to continuously supply stable glue, the design ensures that the glue block is fully broken, avoids the blocking phenomenon, and makes the glue 6 output smooth, thereby improving the working efficiency of the extruder.

[0032] The surface of the glue scraping gear 4 is coated with a non-stick lubricant, which can effectively reduce the adhesion of the glue 6, reduce the friction and running resistance of the gear, and make the gear more smoothly break the glue and continuously run; the coating design can reduce the adhesion of the glue block, improve the self-cleaning effect of the gear, thereby reducing the frequency of equipment cleaning and maintenance, and prolonging the service life.

[0033] The non-stick lubricant can be replaced by a material with similar properties, such as a Teflon coating, to adapt to different operating environments and material types.

[0034] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
