Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive product processing technology, and in particular to a feeding device for adhesive products. Background Technology
[0002] In the manufacturing process of adhesive products, the mixing, stirring, and feeding of raw materials are crucial steps. Many adhesive products require the use of viscous or even solid adhesive raw materials, which may have poor flowability at room temperature or tend to adhere to the inner wall of the mixing equipment during stirring, causing many inconveniences in production.
[0003] Traditional adhesive product feeding and mixing devices are often relatively simple in structure; for example, some devices may only contain a mixing chamber and a mixing device, with mixing achieved by a motor-driven mixing blade. However, this simple structure has significant drawbacks when dealing with viscous or adhesive raw materials. First, the raw material easily adheres to the inner wall of the mixing chamber during the mixing process, especially in hard-to-clean areas such as the top and corners of the mixing chamber. This not only reduces mixing efficiency and leads to uneven mixing of the raw material, but may also affect subsequent normal production due to excessive adhesion. Second, if the feed inlet is poorly designed or lacks pretreatment, the adhesive material may also adhere and clog near the feed inlet, making feeding difficult and requiring frequent shutdowns for cleaning, which seriously affects production efficiency and continuity.
[0004] To address the above problems, it is necessary to design a feeding device for adhesive products to overcome these issues. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1-3As shown, a feeding device for adhesive products includes a processing box 1, a feeding chamber 2, and a stirring chamber 4. The processing box 1 is equipped with a heating and stirring assembly 5.
[0025] The heating and stirring assembly 5 includes a coupling 501 disposed inside the stirring chamber 4 near the feed chamber 2. A connecting flange 502 is connected to the outer wall of the coupling 501. A drive shaft 503 is connected to the output end of the coupling 501. A stirring roller 509 is connected to the output end of the drive shaft 503. A limit flange 510 is connected to the end of the stirring roller 509 away from the rotating shaft 504. A trapezoidal positioning block 505 is sleeved on one end of the outer wall of the rotating shaft 504. All four sides of the trapezoidal positioning block 505 are connected to... Positioning rod 506, one end of the original trapezoidal positioning block 505 is connected to gear disk 507, one end of the original positioning rod 506 is connected to heating pad 508, the outer wall of the rotating shaft 504 is sleeved with a limit sleeve 511 near the stirring roller 509, the outer wall of the limit flange 510 is connected to a fixing block 512, an arc-shaped heating ring 513 is connected between two adjacent fixing blocks 512, and a heat-conducting rod 514 is connected between two arc-shaped heating rings 513.
[0026] The coupling 501 is connected to the drive shaft 503 via a motor. The drive shaft 503 is rotatably connected to the rotating shaft 504, which is rotatably connected to the stirring roller 509. The stirring roller 509 is rotatably connected to the limiting flange 510. A trapezoidal positioning block 505 is sleeved on one end of the outer wall of the rotating shaft 504. The trapezoidal positioning block 505 is threadedly fixed to four positioning rods 506. The four positioning rods 506 are rotatably connected to the gear disk 507, which is rotatably connected to the heating pad 508. The limiting sleeve 511 and the limiting flange 510 are both threadedly fixed to the fixing block 512. The two fixing blocks 512 are threadedly fixed to the arc-shaped heating ring 513, which is rotatably connected to the heat-conducting rod 514.
[0027] When the raw material comes into contact with the discharge port equipped with a heating pad 508 at the bottom of the feeding chamber 2, the heating pad 508 starts working to preheat the raw material, reducing its viscosity and making it easier for it to enter the mixing chamber 4 through the discharge port. After the raw material enters the mixing chamber 4, the stirring roller 509 starts working to stir and mix the raw material. The gear disk 507 is precisely fixed by the trapezoidal positioning block 505 and the positioning rod 506 to ensure stable and reliable transmission. The trapezoidal positioning block 505 is fixed on a certain reference surface, which may be the inner wall of the sealed cavity 5 or a specific bracket. The positioning rod 506 passes through the corresponding hole on the gear disk 507 and is inserted into the trapezoidal positioning block 506. In the oblique holes or grooves of 05, this structure utilizes the self-locking property of the trapezoidal surface to accurately and firmly position the gear disk 507 in the predetermined working position, preventing axial movement or misalignment during operation. When the adhesive material passes through the feed port, it first contacts the heating pad 508. After the heating pad 508 is energized, it generates heat to preheat or keep the contacted material warm, reducing its viscosity and making it easier to flow into the mixing chamber 4 and participate in the subsequent mixing process. The heating pad 508 is usually electrically heated and equipped with a temperature control device. The inner shape of each arc-shaped heating ring 513 matches the inner wall shape of the mixing chamber 4. Two arc-shaped heating rings 513 are firmly fixed to the limiting sleeve 511 and the limiting flange 510 by the fixing block 512. After the heating rings 513 are energized, they heat the inner wall of the stirring chamber 4, especially the area where raw materials may adhere, so that the adhered raw materials are softened or melted. When the heating rings 513 heat the inner wall of the stirring chamber, the heat conduction rod 514 can assist in conducting heat, or when necessary, it can be used in conjunction with water flow to physically impact the adhered material and promote its removal.
[0028] A sealing plate 3 is connected to the top of the processing box 1 away from the feeding chamber 2. A fixing plate 6 is connected to the inner side of the processing box 1 away from the mixing chamber 4. A locking rod 7 is connected to one side of the fixing plate 6. An arc-shaped limiting plate 8 is connected to the end of the locking rod 7 away from the fixing plate 6. A horizontal pipe 9 is connected to the top of the arc-shaped limiting plate 8. Multiple nozzles 10 are connected to the side of the horizontal pipe 9 that was originally fixed plate 6.
[0029] The sealing plate 3 is slidably connected to the groove opened at one end of the top of the processing box 1 via a slider. The fixing plate 6 is threadedly fixed to the locking rod 7. The locking rod 7 is threadedly fixed to the arc-shaped limiting plate 8. The top of the arc-shaped limiting plate 8 contacts the horizontal pipe 9. The horizontal pipe 9 is rotatably connected to multiple nozzles 10. The multiple nozzles 10 pass through the mixing chamber 4 on one side away from the horizontal pipe 9 and contact its interior on the other side.
[0030] In this process, the sealing plate 3 is slid along the groove on the top of the processing box 1 to a designated position. The initial seal is achieved by the cooperation between the sealing plate 3 and the top wall of the processing box 1 to prevent external impurities from entering. The adhesive raw material to be processed is put into the feeding chamber 2 through the opening on the top of the processing box 1. When the raw material comes into contact with the discharge port with heating pad 508 at the bottom of the feeding chamber 2, the heating pad 508 starts to work, preheating the raw material and reducing its viscosity, making it easier for it to enter the mixing chamber 4 through the discharge port. During the mixing process, the water source is turned on as needed, and the water flow is delivered to each nozzle 10 through the horizontal pipe 9. The nozzle 10 sprays water mist or water flow onto the adhesive raw material being mixed and the inner wall of the mixing chamber 4. This water film can effectively isolate the raw material from direct contact with the inner wall, preventing the raw material from adhering to the chamber wall during the mixing process. At the same time, the evaporation and flow of water carry away the heat generated by the mixing, playing a good cooling role and preventing the raw material from degrading in performance or undergoing adverse reactions due to overheating.
[0031] It should be noted that this utility model is a feeding device for adhesive products. In use, firstly, the raw material of the adhesive product enters the mixing chamber 4 through the feeding chamber 2. During the falling process of the raw material, it will first come into contact with the heating pad 508 set below the feeding chamber 2. The heating pad 508 is energized and heats up, which initially heats the raw material that it first comes into contact with. This helps to soften some of the solid or semi-solid raw material, reduce its initial viscosity, and make it easier for it to enter the mixing chamber 4 and begin to flow. Secondly, the motor starts and drives the transmission shaft 503 to rotate through the coupling 501 and the connecting flange 502. The transmission shaft 503 drives the mixing roller 509 to rotate in the mixing chamber 4. The rotation of the mixing roller 509 strongly mixes and stirs the adhesive raw material that has entered the mixing chamber 4 and has been initially heated, so as to make it homogenized. At the same time as stirring, the rotating shaft 504 drives the trapezoidal positioning block 505 on it to rotate synchronously. The trapezoidal positioning block 505 drives the four gear disks 507 to rotate through the positioning rods 506 on its four sides. The gear disk 507 drives the heating pad 508 to rotate synchronously. The continuous rotation of the heating pad 508 ensures the continuous heating effect on the path of the raw material falling, and provides supplementary heating to the edge of the raw material near the feed chamber 2. Then, during the stirring process, water is delivered into the stirring chamber 4 through the horizontal pipe 9. Water is evenly sprayed through multiple nozzles 10 onto the adhesive material being stirred and onto the inner wall of the stirring chamber 4. The water can wet the adhesive material, reducing its direct contact with the metal stirring chamber wall and lowering the adhesion. Frictional heat may be generated during the stirring process, and the water spray can absorb some of the heat, preventing the material from overheating and keeping it mixed within a suitable temperature range. This is especially important for some temperature-sensitive adhesives. Finally, the limiting sleeve 511 and limiting flange 510 on the stirring shaft restrict the axial movement of the stirring assembly. The fixing block 512 fixes two arc-shaped heating rings 513 between the limiting sleeve 511 and the limiting flange 510. These two arc-shaped heating rings 513 are energized and heat up, closely adhering to or near the inner wall of the stirring chamber 4. For the material that may have adhered to the inner wall of the stirring chamber 4 in small amounts during the stirring process, the heat generated by the arc-shaped heating rings 513 will continue to act on these areas, causing the adhered material to soften due to heat.
