Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive pelletizers, and in particular to a hot melt adhesive pelletizer. Background Technology

[0002] In industrial production, hot melt adhesives are widely used as bonding materials in industries such as packaging, electronics, automotive, and medical. Granulation is a crucial step in the production process. As industries continuously raise their requirements for hot melt adhesive product quality and production efficiency, optimizing the performance of hot melt adhesive pelletizing equipment has become an important direction for technological development in the industry.

[0003] Shortcomings of existing technology:

[0004] 1) Insufficient processing efficiency and temperature control accuracy: Traditional hot melt adhesive pelletizers mostly use external heating methods, which can easily lead to uneven local temperatures during the hot melt adhesive transportation process. This results in fluctuations in the viscosity of the hot melt adhesive, affecting not only the pelletizing quality but also reducing the overall processing efficiency. At the same time, the cooling system often relies on air cooling or simple water cooling, which is slow and cannot meet the requirements for rapid curing of hot melt adhesive, thus limiting the equipment's production capacity.

[0005] 2) Poor pelletizing accuracy and equipment flexibility: Existing pelletizers often use a single motor to directly drive the blades, resulting in uneven cutting force distribution and a tendency to produce unqualified products such as pellets that are stuck together or broken, with large errors in pellet size. In addition, the equipment has a fixed discharge gap, making it difficult to adapt to hot melt adhesive raw materials with different viscosities and yields, failing to meet diverse production needs, and the equipment is inconvenient to maintain, has poor structural stability, and is difficult to operate stably for a long time.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figures 1-5 As shown, this utility model provides as follows Figure 1As shown, the hot melt adhesive pelletizer of this embodiment includes a mounting plate 1. A first bracket 11 is fixedly connected to the top of the mounting plate 1. A mounting frame 12 is fixedly connected to the outer surface of the first bracket 11. A heating transmission mechanism 3 is provided on the top of the mounting frame 12. The heating transmission mechanism 3 includes a first motor 301. A first gear 302 is fixedly connected to the output end of the first motor 301. A gear ring 303 meshes with the outer wall of the first gear 302. A conveying sleeve 304 is fixedly connected to the outer surface of the gear ring 303. A auger blade 305 is fixedly welded to the outer wall of the conveying sleeve 304. A shell 306 is movably sleeved on the outer wall of the auger blade 305. A transmission column 307 is movably inserted inside the conveying sleeve 304. A set of heating components 308 is embedded in the outer wall of the transmission column 307. A pin 309 is fixedly connected to one end of the transmission column 307. A conical conveying cylinder 310 is fixedly connected to one end of the shell 306. A cooling sleeve 311 is fixedly connected to one end of the pin 309.

[0026] The overall effect of Embodiment 1 is to achieve efficient delivery and precise heating of hot melt adhesive. The first motor 301 drives the first gear 302, which drives the gear ring 303 to rotate, thereby causing the delivery sleeve 304 fixed on the gear ring 303 to rotate. The auger blades 305 welded to the outer wall of the delivery sleeve 304 stir the hot melt adhesive, ensuring that the raw material is fully stirred during the delivery process, avoiding local accumulation or solidification of the hot melt adhesive, and ensuring smooth delivery. The heating component 308 embedded in the outer wall of the transmission column 307 can directly heat the hot melt adhesive in the delivery sleeve 304, precisely control the temperature, and keep it in a good melting state, laying the foundation for subsequent molding and pelletizing. The ejector pin 309 is fixedly connected to the cooling sleeve 311, which allows the hot melt adhesive to quickly enter the cooling sleeve 311 through the conical delivery cylinder 310, shortening the transition time, reducing heat loss, and improving the overall processing efficiency.

[0027] Example 2: Figures 1-5 As shown, a cutting mechanism 4 is fixedly installed at one end of the cooling sleeve 311; the cutting mechanism 4 includes a mounting rotating plate 401, an extrusion mesh 402 is rotatably connected to the outer surface of the mounting rotating plate 401, a second gear 403 is meshed on the outer wall of the extrusion mesh 402, a set of cutting blades 404 is fixedly installed on the outer surface of the second gear 403, a third gear 405 is meshed on the outer wall of the second gear 403, and the output end of a second motor 406 is fixedly connected to the outer surface of the third gear 405.

[0028] The overall effect of embodiment 2 is that the design of the cutting mechanism 4 greatly improves the precision and efficiency of pelletizing. The second motor 406 drives the third gear 405 to rotate. Through the gear meshing relationship, the second gear 403 and the cutting tool 404 fixed on its outer surface are driven to rotate at high speed. At the same time, the extrusion mesh 402 meshes with the second gear 403 and rotates. When the cooling sleeve 311 outputs the cured hot melt adhesive strip, the extrusion mesh 402 first limits and initially extrudes the adhesive strip to make its shape regular. Then, the high-speed rotating cutting tool 404 accurately cuts the adhesive strip into uniform particles. This linkage structure not only ensures the consistency of the pellet size and reduces the waste generated due to size deviation, but also improves the surface quality of the pellets through the dual action of extrusion and cutting.

[0029] Example 3: As Figures 1-5 As shown, a second bracket 13 is fixedly connected to the top of the mounting plate 1. The mounting base of the second motor 406 is fixedly installed to the top of the second bracket 13. The outer wall of the outer shell 306 is fixedly connected to the top of the first bracket 11. The outer wall of the outer shell 306 is fixedly connected to the crusher 5, which is the feed end of the machine. A third bracket 14 is fixedly installed to the top of the mounting plate 1. An electric telescopic rod 6 is fixedly installed to the top of the third bracket 14. The output end of the electric telescopic rod 6 is fixedly connected to one end of the transmission column 307. The outer wall of the ejector pin 309 and the inner wall of the cooling sleeve 311 cooperate with each other.

[0030] The overall effect of embodiment 3 is that, through the reasonable layout and connection of multiple components, the overall stability and operational flexibility of the equipment are enhanced. The second bracket 13 is fixedly installed with the second motor 406, and the first bracket 11 is fixedly connected with the outer shell 306, so that the key components of the equipment are firmly installed, and vibration can be effectively reduced during operation, extending service life. The crusher 5 serves as the feed end, which can pre-crush the blocky hot melt adhesive raw materials, making it easier to transport and heat them in the conveying sleeve 304, thereby improving processing efficiency. The electric telescopic rod 6 is connected to the transmission column 307, which can flexibly adjust the position of the ejector pin 309 according to production needs, thereby changing the degree of fit between the ejector pin 309 and the inner wall of the cooling sleeve 311, controlling the extrusion amount and speed of the hot melt adhesive, and adapting to the production of pellets of different specifications. The precise fit between the ejector pin 309 and the inner wall of the cooling sleeve 311 can also prevent hot melt adhesive leakage and ensure the stability and reliability of the cooling and molding process.

[0031] Working principle: During operation, the blocky hot melt adhesive raw material is first fed into the crusher 5. The crusher 5 crushes the raw material and sends it into the feed inlet that is fixedly connected to the outer shell 306. The first motor 301 starts, driving the first gear 302 to rotate the gear ring 303, causing the conveying sleeve 304 and the auger blades 305 to rotate, conveying the crushed hot melt adhesive forward inside the outer shell 306. During this process, the heating component 308 on the outer wall of the transmission column 307 continuously heats the hot melt adhesive, keeping it in a molten state. The hot melt adhesive passes through the conical conveying cylinder 310 and enters the cooling sleeve 311 through the ejector pin 309. The cooling medium circulating inside the cooling sleeve 311 quickly removes the heat from the hot melt adhesive. The adhesive strip is quickly cured into a strip. After extending from the cooling sleeve 311, the strip enters the cutting mechanism 4. At this time, the second motor 406 operates, driving the third gear 405 and the second gear 403 to rotate, causing the extrusion mesh 402 and the cutting tool 404 to move synchronously. The extrusion mesh 402 limits and compresses the strip to make it regular in shape. Then, the high-speed rotating cutting tool 404 cuts the strip into granules. The electric telescopic rod 6 can adjust the position of the transmission column 307 in real time according to actual production needs, changing the relative position of the ejector pin 309 and the cooling sleeve 311, thereby controlling the extrusion amount of hot melt adhesive and the forming speed of the strip, and realizing the production of hot melt adhesive granules of different specifications.

[0032] The wiring diagrams of the first motor 301, heating component 308, cooling sleeve 311, extrusion mesh 402, cutting tool 404, and second motor 406 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the first motor 301, heating component 308, cooling sleeve 311, extrusion mesh 402, cutting tool 404, and second motor 406 will not be explained in detail.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
