Description

Technical Field

[0001] This utility model relates to the field of double-sided tape production technology, specifically to a raw material mixer for double-sided tape production. Background Technology

[0002] Double-sided tape production raw material mixers are used to uniformly mix adhesives with other raw materials such as resins and fillers to ensure the quality and consistency of the adhesive during the production process. These mixers are typically equipped with high-efficiency stirring devices that can achieve thorough mixing of raw materials through different speeds and stirring modes, ensuring stable adhesion performance of the tape products to meet the needs of different types of adhesives.

[0003] A raw material mixer disclosed in Chinese Patent Publication No. CN219849016U uses a blower to blow air into a pipe, causing the raw material in the T-joint to be sucked into the pipe. In a dust collector, the raw material in the air is separated and reintroduced into the mixing tank. In this way, the material moves downward while running under the mixing rollers, increasing the range of motion of the raw material and making the raw material mix faster. However, the overall functionality of the mixer is low. The adhesive may adhere to the inside of the mixer, which will cause blockage after long-term use. At the same time, the adhesive discharge rate is slow, which affects the overall working effect of the mixer. Utility Model Content

[0004] The purpose of this invention is to provide a raw material mixer for double-sided tape production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material mixer for double-sided tape production, comprising a mixing chamber, a linkage mechanism being provided at the middle position of the top of the mixing chamber, a first rotating rod being provided at the middle position of the bottom of the linkage mechanism, a second rotating rod being provided on the outer side of the bottom of the linkage mechanism, an electric heating plate being installed inside the mixing chamber, and a material layer being provided inside the mixing chamber.

[0006] Preferably, a feed inlet is installed at the top of one side of the mixing chamber, and a discharge outlet is installed at the middle of the bottom of the mixing chamber.

[0007] Preferably, toothed blocks are evenly spaced at the top of one side of the mixing chamber, and an annular groove is provided at the top of the mixing chamber. The linkage mechanism includes a drive motor installed at the middle position of the top of the mixing chamber. A first gear with its bottom end fixedly connected to a first rotating rod is installed on the output shaft end of the drive motor. A second gear with its bottom end fixedly connected to a second rotating rod is slidably connected inside the annular groove. The two sides of the second gear mesh with the toothed blocks and the first gear, respectively.

[0008] Preferably, stirring blades are evenly and uniformly fixedly connected to the outside of the first rotating rod, pushing blades are fixedly connected to both sides of the bottom outside of the first rotating rod, and scrapers are fixedly connected to both sides of the bottom outside of the second rotating rod.

[0009] Preferably, the material layer includes a strength layer disposed inside the mixing chamber, a protective layer disposed inside the strength layer, and a composite layer disposed outside the strength layer.

[0010] Preferably, the strength layer is made of carbon steel, the protective layer is made of aluminum alloy, and the composite layer is a mixture of PTFE and glass fiber reinforced plastic.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This type of raw material mixer for double-sided tape production has a linkage mechanism installed at the top of the mixing chamber. When the drive motor on the linkage mechanism is started, it can drive the first gear to rotate. At the same time, the first gear can drive the second gear to rotate. At this time, the first gear and the second gear can drive the first rotating rod and the second rotating rod to rotate respectively. The stirring blade on the first rotating rod can quickly stir the raw material inside the mixing chamber. Meanwhile, the scraper on the second rotating rod can scrape the inner wall of the mixing chamber while stirring the raw material. The pushing blade on the first rotating rod can stir the raw material discharged from the discharge port, thereby effectively accelerating the discharge of raw material in the mixer and improving the overall functionality and overall performance of the raw material mixer.

[0013] 2. This type of raw material mixer for double-sided tape production features a strength layer, a protective layer, and a composite layer within the mixing chamber. The strength layer increases the overall strength of the mixer, while the lightweight yet high-strength protective layer enhances the equipment's external oxidation resistance. The composite layer within the strength layer provides excellent corrosion resistance, a very low coefficient of friction, and superior chemical stability, preventing adhesive materials from adhering to the inner wall of the mixer. This allows the raw material mixer for double-sided tape production to exhibit superior performance under various working conditions. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides two technical solutions:

[0021] Example 1: A raw material mixer for double-sided tape production includes a mixing chamber 1. A linkage mechanism 2 is provided at the middle position of the top of the mixing chamber 1. A first rotating rod 3 is provided at the middle position of the bottom of the linkage mechanism 2. A second rotating rod 4 is provided on the outer side of the bottom of the linkage mechanism 2. An electric heating plate 5 is installed inside the mixing chamber 1. A material layer 6 is provided inside the mixing chamber 1.

[0022] A feed inlet 101 is installed at the top of one side of the mixing chamber 1, and a discharge outlet 102 is installed at the middle of the bottom of the mixing chamber 1. The feed inlet 101 and the discharge outlet 102 can respectively carry out the feeding and discharging of double-sided tape adhesive raw materials.

[0023] The top of one side of the mixing chamber 1 is evenly spaced with toothed blocks 103. The top of the mixing chamber 1 is provided with an annular groove 104. The linkage mechanism 2 includes a drive motor 201 installed at the middle position of the top of the mixing chamber 1. The output shaft of the drive motor 201 is equipped with a first gear 202 whose bottom end is fixedly connected to the first rotating rod 3. The annular groove 104 is slidably connected with a second gear 203 whose bottom end is fixedly connected to the second rotating rod 4. The two sides of the second gear 203 mesh with the toothed blocks 103 and the first gear 202 respectively. When the drive motor 201 is started, it can drive the first gear 202 to rotate. Then the first gear 202 can drive the first rotating rod 3 below to rotate. At this time, the first gear 202 can push the second gears 203 on both sides to rotate. At the same time, the second gear 203 contacts the toothed blocks 103, so that the second gear 203 can rotate around the midpoint of the first gear 202 outside the first gear 202.

[0024] Agitator blades 301 are evenly and uniformly fixedly connected to the outside of the first rotating rod 3. Pusher blades 302 are fixedly connected to both sides of the bottom of the outside of the first rotating rod 3. Scrapers 401 are fixedly connected to both sides of the bottom of the outside of the second rotating rod 4. The rotation of the first rotating rod 3 can drive the agitator blades 301 and pusher blades 302 to rotate. At this time, the agitator blades 301 can stir and mix the double-sided adhesive liquid inside the mixing chamber 1. At the same time, the pusher blades 302 can stir the adhesive liquid at the discharge port 102, thereby accelerating the discharge of the adhesive liquid. The second rotating rod 4 drives the scraper blades 401 to rotate, so that the scraper blades 401 can stir the internal adhesive liquid and scrape the inner wall of the mixing chamber 1 at the same time to prevent the adhesive liquid from adhering to the inner wall of the mixing chamber 1.

[0025] Example 2 differs from Example 1 mainly in that:

[0026] A raw material mixer for double-sided tape production includes a strength layer 601 inside a mixing chamber 1 in a material layer 6. A protective layer 602 is provided inside the strength layer 601, and a composite layer 603 is provided outside the strength layer 601. The strength layer 601 is made of carbon steel, which has high mechanical strength and is suitable for withstanding large physical pressure. At the same time, the cost is relatively low, saving the cost of using the raw material mixer.

[0027] The protective layer 602 is made of aluminum alloy, which is lightweight and high-strength, has good oxidation resistance, and can effectively reduce the overall weight of the equipment.

[0028] The composite layer 603 is a mixture of PTFE and glass fiber reinforced plastic. Glass fiber has good corrosion resistance and chemical resistance, which can effectively resist the erosion of various chemical raw materials. At the same time, PTFE has a very low coefficient of friction and excellent chemical stability, which can prevent adhesive raw materials from adhering to the inner wall of the mixer, making it easy to clean and reducing material waste. In addition, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0029] In this embodiment, the double-sided adhesive liquid raw material to be mixed can be poured into the mixing chamber 1 through the discharge port 102. At this time, the internal adhesive liquid raw material can be heated by starting the electric heating plate 5, and the first gear 202 can be rotated by starting the drive motor 201. At this time, the first gear 202 can drive the second gears 203 on both sides to rotate. The first gear 202 and the second gear 203 can respectively drive the first rotating rod 3 and the second rotating rod 4 to rotate. At this time, the stirring blade 301 on the first rotating rod 3 can quickly stir the adhesive liquid in the mixing chamber 1. At the same time, the scraper 401 on the second rotating rod 4 can scrape the inner wall of the mixing chamber 1 while stirring. After the adhesive liquid is stirred, the discharge port 102 at the bottom of the mixing chamber 1 is opened, and the first rotating rod 3 drives the pushing blade 302 to rotate, so that the adhesive liquid can be discharged after stirring.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
