Description

Technical Field

[0001] This utility model relates to the field of pressure-sensitive adhesive production technology, specifically a material cold circulation system for pressure-sensitive adhesive production. Background Technology

[0002] In the production of pressure-sensitive adhesives, material cooling is a crucial step in ensuring product quality. Pressure-sensitive adhesives typically have a certain degree of viscosity, and improper handling during the cooling stage can easily lead to uneven cooling, resulting in unstable material properties and affecting subsequent processing and the final product quality.

[0003] Currently, traditional cooling equipment for pressure-sensitive adhesive production mostly uses a single refrigeration unit to cool the production tank. During the cooling process, localized temperature differences can easily occur due to the material being left to stand or insufficient stirring. Furthermore, viscous materials tend to adhere to the inner wall of the production tank, resulting in material waste and affecting the heat exchange efficiency of the tank wall, further reducing the cooling effect. In addition, the drive systems of existing equipment are often single-function, requiring separate power units for stirring, cooling, and anti-adhesion functions. This not only increases the complexity and energy consumption of the equipment but may also affect production efficiency due to poor coordination between the various units. Therefore, we propose a material cooling circulation system for pressure-sensitive adhesive production to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a material cold circulation system for pressure-sensitive adhesive 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 material cold circulation system for pressure-sensitive adhesive production, comprising a production tank, a cover plate, an auxiliary mechanism, hinges, a fixing frame, a base, a cooling box, and a discharge pipe. The production tank is fixedly connected to the upper side of the base, and a fixing frame is provided on the upper side of the production tank. Hinges are symmetrically arranged on one side of the fixing frame. The cover plate is movably connected to the fixing frame through the hinges. A cooling box is fixedly connected to the base. A cooling fan frame is provided between the cooling box and the production tank. A gear-driven auxiliary mechanism is provided between the production tank and the cooling fan frame.

[0006] Preferably, the auxiliary mechanism includes a drive wheel, a drive rod, a transmission wheel, a movable shaft, a protrusion, a guide groove, a connector, a striking block, a stirring rod, stirring blades, and a drive motor. The drive motor is fixedly connected to the fixed frame, and the output end of the drive motor is fixedly connected to the stirring rod inside the production tank. Multiple stirring blades are evenly arranged on the stirring rod, and the stirring blades cooperate with the surface of the production tank.

[0007] Preferably, the production tank has an installation groove, a driving rod is fixedly connected to the stirring rod in the installation groove, a driving wheel is fixedly connected to the driving rod in the installation groove, and a transmission wheel is symmetrically arranged in the installation groove with the driving wheel as the center, and the transmission wheel and the driving wheel are meshed with each other by gears.

[0008] Preferably, each of the transmission wheels is fixedly connected with a protrusion, and a movable shaft is symmetrically arranged in the mounting groove. The mounting groove is movably connected to a striking block through the movable shaft. A connecting piece is movably connected to one side of the striking block. A guide groove is opened in the middle of the connecting piece, and the protrusion is located in the guide groove.

[0009] Preferably, the surface of the striking block is provided with a pad made of rubber material, and a cooling fan is movably connected inside the cooling fan frame, and the drive rod passes through the production tank and is fixedly connected to the cooling fan.

[0010] Preferably, a refrigeration pipe is arranged in a ring inside the cooling box and is connected to an external refrigeration device, and a discharge pipe is provided on one side of the production tank.

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

[0012] 1. After the drive motor on the fixed frame starts, its output end directly drives the stirring rod inside the production tank to rotate. Multiple stirring blades on the stirring rod rotate synchronously with it. Since the stirring blades cooperate with the inner wall surface of the production tank, the material inside the tank can be fully stirred to ensure uniform cooling. When the stirring rod rotates, it synchronously drives the drive rod in the installation slot inside the production tank to rotate, which in turn causes the drive wheel on the drive rod to rotate. Since the drive wheel and the symmetrically arranged transmission wheel are meshed by gears, the rotation of the drive wheel will drive the two transmission wheels to rotate synchronously in opposite directions, realizing the power splitting and transmission. When the transmission wheel rotates, the protrusion fixed on its surface rotates together. Since the protrusion is embedded in the guide groove of the connector, when the protrusion rotates, it will push the connector to reciprocate through the guide groove. The connector drives the knocking block connected to it to swing periodically around the movable shaft, so that the knocking block continuously knocks the inner wall of the production tank, preventing the material from adhering to the tank wall through vibration.

[0013] 2. The core refrigeration component is the annular refrigeration pipes inside the cooling box. It is connected to external refrigeration equipment through pipes and absorbs heat from the surrounding environment through the principle of heat exchange, keeping the inside of the cooling box at a low temperature. A refrigeration fan frame is installed between the cooling box and the production tank. When the drive rod in the auxiliary mechanism drives the cooling fan to rotate, it will accelerate the airflow between the cooling box and the production tank. The cooling fan blows the cold air in the cooling box to the surface of the production tank, and the heat of the production tank is carried away by air convection. When the pressure-sensitive adhesive material in the production tank reaches the process requirements after cooling treatment, it can be discharged through the discharge pipe on one side of the production tank.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figures 1-4 As shown, the present invention proposes a material cold circulation system for pressure-sensitive adhesive production, including a production tank 1, a cover plate 2, an auxiliary mechanism 3, a hinge 4, a fixing frame 5, a base 6, a cooling box 7, and a discharge pipe 8. The production tank 1 is fixedly connected to the upper side of the base 6, and the fixing frame 5 is provided on the upper side of the production tank 1. The hinge 4 is symmetrically arranged on one side of the fixing frame 5. The cover plate 2 is movably connected to the fixing frame 5 through the hinge 4, and the cooling box 7 is fixedly connected to the base 6. A cooling fan frame 10 is provided between the cooling box 7 and the production tank 1, and a gear-driven auxiliary mechanism 3 is provided between the production tank 1 and the cooling fan frame 10.

[0021] In an optional embodiment, the auxiliary mechanism 3 includes a drive wheel 301, a drive rod 302, a transmission wheel 303, a movable shaft 304, a protrusion 305, a guide groove 306, a connector 307, a striking block 308, a stirring rod 309, stirring blades 310, and a drive motor 311. The drive motor 311 is fixedly connected to the fixed frame 5. The output end of the drive motor 311 is fixedly connected to the stirring rod 309 inside the production tank 1. Multiple stirring blades 310 are evenly arranged on the stirring rod 309, and the stirring blades 310 cooperate with the surface of the production tank 1.

[0022] In an optional embodiment, the production tank 1 is provided with an installation groove 11, the stirring rod 309 is fixedly connected to the driving rod 302 in the installation groove 11, the driving rod 302 is fixedly connected to the driving wheel 301 in the installation groove 11, and the installation groove 11 is symmetrically provided with a transmission wheel 303 with the driving wheel 301 as the center, and the transmission wheel 303 and the driving wheel 301 are meshed with each other.

[0023] In an optional embodiment, each of the transmission wheels 303 is fixedly connected with a protrusion 305, and a movable shaft 304 is symmetrically arranged in the mounting groove 11. The mounting groove 11 is movably connected to a striking block 308 through the movable shaft 304. A connector 307 is movably connected to one side of the striking block 308. A guide groove 306 is opened in the middle of the connector 307, and the protrusion 305 is located in the guide groove 306.

[0024] After the drive motor 311 on the fixed frame 5 starts, its output end directly drives the stirring rod 309 in the production tank 1 to rotate. The multiple stirring blades 310 on the stirring rod 309 rotate synchronously with it. Since the stirring blades 310 cooperate with the inner wall surface of the production tank 1, they can fully stir the material in the tank and ensure uniform cooling of the material. When the stirring rod 309 rotates, it synchronously drives the drive rod 302 in the mounting groove 11 in the production tank 1 to rotate, which in turn causes the drive wheel 301 on the drive rod 302 to rotate. Since the drive wheel 301 and the symmetrically arranged transmission wheels 303 are meshed by gears... The rotation of the drive wheel 301 will drive the two transmission wheels 303 to rotate synchronously in opposite directions, realizing the power splitting and transmission. When the transmission wheel 303 rotates, the protrusion 305 fixed on its surface will rotate together. Since the protrusion 305 is embedded in the guide groove 306 of the connector 307, when the protrusion 305 rotates, it will push the connector 307 to reciprocate through the guide groove 306. The connector 307 drives the knocking block 308 connected to it to swing periodically around the movable shaft 304, so that the knocking block 308 continuously knocks the inner wall of the production tank 1, and prevents the material from adhering to the tank wall through vibration.

[0025] In an optional embodiment, the surface of the striking block 308 is provided with a gasket made of rubber material, and a cooling fan 9 is movably connected inside the cooling fan frame 10, and the drive rod 302 passes through the production tank 1 and is fixedly connected to the cooling fan 9.

[0026] In an optional embodiment, a refrigeration pipe is arranged in a ring inside the cooling box 7 and the refrigeration pipe is connected to an external refrigeration device, and a discharge pipe 8 is provided on one side of the production tank 1.

[0027] The core refrigeration component is the annular refrigeration pipe inside the cooling box 7. It is connected to external refrigeration equipment through pipes and absorbs heat from the surrounding environment through the principle of heat exchange, so as to maintain a low temperature inside the cooling box 7. A refrigeration fan frame 10 is provided between the cooling box 7 and the production tank 1. When the drive rod 302 in the auxiliary mechanism 3 drives the cooling fan 9 to rotate, it will accelerate the air flow between the cooling box 7 and the production tank 1. The cooling fan 9 blows the cold air in the cooling box 7 to the surface of the production tank 1, and removes the heat of the production tank 1 through air convection. When the pressure-sensitive adhesive material in the production tank 1 reaches the process requirements after cooling treatment, it can be discharged through the discharge pipe 8 on one side of the production tank 1.

[0028] The working principle of this utility model is as follows: When using this device, after the drive motor 311 on the fixed frame 5 is started, its output end directly drives the stirring rod 309 in the production tank 1 to rotate. The multiple stirring blades 310 on the stirring rod 309 rotate synchronously with it. Since the stirring blades 310 cooperate with the inner wall surface of the production tank 1, they can fully stir the material in the tank and ensure that the material is cooled evenly. When the stirring rod 309 rotates, it synchronously drives the drive rod 302 in the mounting groove 11 in the production tank 1 to rotate, thereby causing the drive wheel 301 on the drive rod 302 to rotate. Since the drive wheel 301 and the symmetrically arranged transmission... The drive wheel 301 rotates through gear meshing, which drives the two transmission wheels 303 to rotate in opposite directions synchronously, thus realizing the power splitting and transmission. When the transmission wheel 303 rotates, the protrusion 305 fixed on its surface rotates together. Since the protrusion 305 is embedded in the guide groove 306 of the connector 307, when the protrusion 305 rotates, it will push the connector 307 to reciprocate through the guide groove 306. The connector 307 drives the knocking block 308 connected to it to swing periodically around the movable shaft 304, so that the knocking block 308 continuously knocks the inner wall of the production tank 1, and prevents the material from adhering to the tank wall through vibration.

[0029] Meanwhile, after the drive rod 302 passes through the production tank 1, its other end is directly connected to the cooling fan 9 inside the cooling fan frame 10. When the drive rod 302 rotates, it drives the cooling fan 9 to rotate synchronously, accelerating the air circulation between the cooling box 7 and the production tank 1, enhancing the cooling effect, and forming a cold cycle.

[0030] The core refrigeration component is the annular refrigeration pipe inside the cooling box 7. It is connected to external refrigeration equipment through pipes and absorbs heat from the surrounding environment through the principle of heat exchange, so as to maintain a low temperature inside the cooling box 7. A refrigeration fan frame 10 is provided between the cooling box 7 and the production tank 1. When the drive rod 302 in the auxiliary mechanism 3 drives the cooling fan 9 to rotate, it will accelerate the air flow between the cooling box 7 and the production tank 1. The cooling fan 9 blows the cold air in the cooling box 7 to the surface of the production tank 1, and removes the heat of the production tank 1 through air convection. Finally, when the pressure-sensitive adhesive material in the production tank 1 reaches the process requirements after cooling treatment, it can be discharged through the discharge pipe 8 on one side of the production tank 1.
