[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3The utility model provides an embodiment: a reaction kettle for hot melt pressure sensitive adhesive processing, comprising a kettle body 1, a motor 3 is fixedly connected to the top of the kettle body 1, a connecting column 13 is fixedly connected to the output end of the motor 3, a connecting plate 18 is fixedly connected to the bottom of the connecting column 13, a fixed plate 10 is fixedly connected to the outside of the connecting column 13, two slide grooves 20 are provided inside the fixed plate 10, a slide plate 19 is slidably connected to the inside of the slide groove 20, a connecting column 14 is fixedly connected to the bottom of the slide plate 19, and the connecting column The outside of 14 is fixedly connected with a middle gear 12, the inner wall of the kettle body 1 is fixedly connected with a gear ring 11, the outside of the connecting column 14 is fixedly connected with a plurality of mixing plates 15, one end of the mixing plate 15 is fixedly connected with a reset column 16, and the other end of the reset column 16 is fixedly connected with a scraper 17, a quantitative component is installed on the top of the kettle body 1, the outer side of the middle gear 12 is meshed with the inner side of the gear ring 11, the outer side of the scraper 17 is in contact with the inner wall of the kettle body 1, and the outer side of the connecting plate 18 is in contact with the inner bottom wall of the kettle body 1.

[0032] Specifically, the driving action of the motor 3 enables the stirring system inside the reactor to operate efficiently. Driven by the motor 3, the connecting column 13 and the fixed plate 10 are rotated, thereby driving the mixing plate 15 and the scraper 17 to stir and clean. The synergistic effect of the mixing plate 15 and the Y-shaped stirring column on the connecting column 13 ensures the uniform mixing of the raw materials. The mixing plate 15 stirs inside the reactor with its specific shape and arrangement, and the Y-shaped stirring column further enhances the stirring effect, so that the raw materials can be fully contacted and mixed during the processing. The reset column 16 can ensure that the scraper 17 is always tightly fitted with the inner wall of the reactor. The reset column 16 is composed of a spring and a telescopic rod. The tight fit ensures that the raw materials will not remain on the inner wall of the kettle body 1 during the stirring process, thereby avoiding the waste of raw materials and the instability of product quality. Ensure the full mixing of raw materials and the uniform progress of the reaction. This not only improves production efficiency, but also ensures product quality and use effect. And avoids the trouble of difficult cleaning of the inner wall hanging material when cleaning the reactor. The connecting plate 18 can tightly connect the stirring system and the bottom of the reactor to ensure the uniformity and stability of stirring.

[0033] Reference Figure 1 , Figure 2 , Figure 4The utility model provides an embodiment: a quantitative component includes a feeding box 4, the outside of the feeding box 4 is fixedly connected to the top of the kettle body 1, one side of the feeding box 4 is fixedly connected with a mounting plate 7, the outside of the mounting plate 7 is fixedly connected with a motor 26, the output end of the motor 26 is fixedly connected with a fan gear 23, the inside of the mounting plate 7 is provided with a mounting cavity 21, the inside of the mounting cavity 21 is slidably connected with a movable plate 24, one side of the movable plate 24 is fixedly connected with a clamping plate 9, and the other side of the movable plate 24 is fixedly connected with two racks 22, the outside of the rack 22 is slidably connected to the inner wall of the mounting cavity 21, one end of the clamping plate 9 is slidably connected to the inside of the feeding box 4, the outside of the fan gear 23 is rotatably connected to the inside of the mounting cavity 21, and the outside of the fan gear 23 is meshed with the outside of the rack 22.

[0034] Specifically, the meshing design of the sector gear 23 and the rack 22 realizes a precise transmission mechanism. The sector gear 23 rotates under the drive of the motor 26, and through the meshing with the rack 22, the rotational motion is converted into linear motion, thereby driving the movable plate 24 to slide in the installation cavity 21. The movable plate 24 moves under the drive of the rack 22, and then drives the card plate 9 to slide inside the feeding box 4. When the card plate 9 moves to the exit position of the feeding box 4, the feeding box 4 opens and the raw materials are put in. When the card plate 9 moves away from the exit position, the feeding box 4 closes to prevent the raw materials from continuing to be put in. This automatic control method not only improves production efficiency, but also reduces human intervention and reduces the possibility of operating errors. The design of the quantitative component also embodies the concept of energy saving and environmental protection. By accurately controlling the amount of raw materials put in, the waste of raw materials is avoided and the production cost is reduced.

[0035] Reference Figure 1 , Figure 2 The utility model provides an embodiment: a discharge box 5 is fixedly connected to the middle end of the bottom of the kettle body 1, a valve 8 is provided on the discharge box 5, and support legs 2 are fixedly connected to the four corners of the bottom of the kettle body 1, and anti-slip patterns are provided on the bottom of the support legs 2.

[0036] Specifically, the arrangement of the discharge box 5 and the valve 8 enables the materials after the reaction to be discharged conveniently and quickly. This design greatly simplifies the operation process and improves production efficiency. The anti-slip pattern design at the bottom of the support leg 2 effectively increases the friction between the support leg 2 and the ground, thereby improving the stability of the entire device.

[0037] Working principle: First, the staff adds the raw materials into the feeding box 4, and then starts the motor 26. When the motor 26 is started, the sector gear 23 is driven to rotate, so that one of the racks 22 is driven to slide on the inner wall of the installation cavity 21, and the movable plate 24 is driven to move, so that the card plate 9 is separated from the inside of the feeding box 4, and the raw materials in the feeding box 4 are released. The sector gear 23 rotates to the outside of another rack 22 to contact it, and drives it to move, thereby closing the feeding box 4. In this way, intermittent feeding is realized, which improves the precise control during the feeding process compared to manual feeding, and ensures the stability and consistency of product quality.

[0038] After the feeding is completed, the motor 13 is started, and the connecting column 13 is driven to rotate under the start of the motor 13, and the fixed plate 10 is driven to rotate. When the connecting column 13 rotates, the connecting plate 18 is driven to rotate, so that the connecting column 14 rotates, and the middle gear 12 is driven to rotate. The middle gear 12 rotates inside the gear ring 11. Among them, the reset column 16 is composed of a spring and a telescopic rod, and the scraper 17 is tightly fitted with the inner wall of the kettle body 1, and the connecting plate 18 is fitted with the inner bottom wall of the kettle body 1. A plurality of Y-shaped stirring columns are installed on the outside of the connecting column 13. The raw materials are uniformly stirred during processing, so that the raw materials are evenly heated during the processing process, thereby improving the quality and use effect of the product. And avoid the trouble of the inner wall hanging material being difficult to clean when the reactor is cleaned. When it is necessary to discharge the material, the valve 8 is pulled open by the handle, and the finished product comes out of the discharge box 5. After the discharge is completed, the valve 8 is closed by pushing the handle to complete the discharge.
