Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically to a sealant extruder head cooling extrusion device. Background Technology

[0002] In the existing self-sealing tire manufacturing process, self-sealing adhesive is the main raw material, and it is mainly produced using a screw extruder. However, the screw extruder generates high heat during processing, resulting in extruded self-sealing adhesive with a high temperature, which cannot be stored directly and must be cooled to room temperature to meet storage requirements.

[0003] Currently, common cooling methods include natural cooling, air cooling, and water cooling. However, natural cooling takes a long time, making it difficult to meet the demands of high-efficiency production; while air cooling can accelerate the cooling process, its effectiveness is greatly affected by ambient temperature and wind speed, making stable control difficult; and although water cooling can quickly lower the temperature, it can easily lead to moisture or contamination on the surface of the self-sealing adhesive, affecting its subsequent performance. Therefore, existing cooling methods suffer from problems such as low cooling efficiency, uneven cooling, or negative impacts on the performance of self-sealing adhesives in practical applications. Utility Model Content

[0004] The purpose of this invention is to provide a cooling extrusion device for the die head of a sealant extruder, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealant extruder head cooling extrusion device, comprising:

[0006] Extrusion mechanism for extruding self-sealing adhesive;

[0007] The cooling mechanism, connected to the extrusion mechanism, is used to cool the self-sealing adhesive.

[0008] Preferably, the extrusion mechanism includes a screw, one end of which is fixed with a pressure plate by bolts, and a sealing ring is attached to the side of the pressure plate near the screw.

[0009] Preferably, the cooling mechanism includes a cooling cylinder, one end of which is provided with an end cap, a cooling channel is provided inside the cooling cylinder, the screw is disposed in the cooling channel, and a cooling water inlet and a cooling water outlet are provided outside the cooling cylinder.

[0010] Preferably, the cooling water inlet is connected to the cooling channel, and the cooling water return outlet is connected to the cooling channel.

[0011] Preferably, the bottom end of the cooling cylinder is provided with a glue outlet.

[0012] Preferably, it further includes an opening and closing mechanism connected to the cooling mechanism.

A shaft is provided on the movable frame. A positioning pin is provided on the shaft. A locking nut is also provided on the pin. A bushing is also provided on the shaft. A pin is provided at the top of the shaft. A groove is opened on the movable frame. A pin slides in the groove on the movable frame.

[0013] Preferably, a bearing is provided on the outside of the pin, and a washer is fixed to the side of the pin.

[0014] Preferably, it further includes a locking mechanism disposed on the opening and closing mechanism. The locking mechanism includes a locking pin fixed to the mouth-shaped end cap, a locking rod fixed to the locking pin, a pull plate fixed to the locking rod, and a locking head fixed to one end of the locking rod.

[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0016] This sealant extruder head cooling extrusion device utilizes cooling channels within the cooling barrel and circulating water cooling via cooling inlets and outlets. This allows the self-sealing adhesive to rapidly cool to a suitable temperature during extrusion, effectively solving the low cooling efficiency problems of traditional natural and air cooling methods and improving production efficiency. Optimizing the internal structure of the cooling barrel ensures uniform distribution of the cooling medium, guaranteeing even heating of the extruded sealant throughout the cooling process and preventing localized overcooling or overheating. This reduces changes in adhesive properties caused by uneven cooling, improving product quality. The closed cooling channels effectively isolate cooling water from the sealant, preventing moisture from affecting its properties, improving storage stability, and ensuring the sealant's performance. The connecting brackets, moving frames, and pins allow for quick assembly and disassembly of the cooling mechanism, facilitating equipment maintenance and cleaning. In addition, the locking mechanism is used to fix the end cap, which improves the stability of the device and avoids the decrease in cooling effect caused by vibration or displacement. The extrusion mechanism of the device includes a screw, a pressure plate and a sealing ring, which can be adapted to different models of sealant extrusion production equipment, achieving good compatibility and suitable for the production needs of self-sealing adhesives of different specifications.

[0025] 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.

[0026] like Figures 1-7 As shown, a sealant extruder head cooling extrusion device includes: an extrusion mechanism 1 for extruding sealant; and a cooling mechanism 2 connected to the extrusion mechanism 1 for cooling the sealant. The extrusion mechanism 1 of this sealant extruder head cooling extrusion device is mainly used to extrude the sealant from the feeding end and apply appropriate pressure to ensure it passes evenly through the die head. After extrusion, the sealant enters the cooling mechanism 2. The cooling mechanism 2, by setting a suitable cooling method, such as water cooling, air cooling, or other cooling media, rapidly cools the sealant after extrusion, achieving a stable molding effect and avoiding the impact of excessive high-temperature fluidity on the final performance. This device uses the cooling mechanism 2 to cool the sealant, enabling it to cure rapidly after extrusion, improving product consistency and stability. Simultaneously, by reasonably controlling the cooling rate, internal stress problems caused by uneven cooling of the sealant can be effectively prevented, improving the quality of the sealant products. Furthermore, this device can adapt to different types of sealant materials, exhibiting strong applicability.

[0027] In the above scheme, the cooling mechanism 2 can employ different cooling methods, such as water cooling, air cooling, or other cooling media, to adapt to different types of sealant materials and production needs. Furthermore, the structure of the extrusion mechanism 1 can be adjusted according to specific application scenarios, such as using single-screw extrusion or twin-screw extrusion to optimize extrusion efficiency and sealant uniformity. The cooling path and flow channel design of the cooling mechanism 2 can also be optimized to improve cooling effect and energy efficiency.

[0028] The extrusion mechanism 1 includes a screw 101, with a pressure plate 102 bolted to one end of the screw 101. A sealing ring 103 is attached to the side of the pressure plate 102 closest to the screw 101. During rotation, the screw 101 pushes the sealant towards the extruder head and increases the extrusion pressure of the sealant via the pressure plate 102, ensuring stable material delivery. The pressure plate 102 effectively improves the pressure stability of the sealant, preventing uneven material flow from affecting extrusion quality. Furthermore, the sealing ring 103, attached to the side of the pressure plate 102 closest to the screw 101, reduces sealant leakage during extrusion, improves extrusion efficiency, and enhances the system's sealing performance, preventing energy loss or material waste due to poor sealing. This device achieves efficient extrusion and sealing of the sealant through the synergistic action of the screw 101, pressure plate 102, and sealing ring 103, ensuring the stability and consistency of the extrusion process. The addition of the pressure booster plate 102 increases the extrusion pressure of the sealant, ensuring uniform flow of the material during processing and reducing product defects caused by unstable pressure. The fitting design of the sealing ring 103 further improves the sealing performance of the device, reduces material loss, increases production efficiency, and extends the equipment's service life. Furthermore, this design is suitable for sealant materials of different viscosities and properties, exhibiting strong applicability and scalability.

[0029] In the above scheme, the screw 101 can adopt different thread structures, such as single-start or multi-start threads, to adapt to different sealant viscosities and extrusion requirements. The diameter, thickness, and material of the pressure plate 102 can be adjusted according to actual production needs to optimize pressure transmission. The sealing ring 103 can be made of different types of wear-resistant, high-temperature resistant, or corrosion-resistant materials, such as rubber sealing rings, polytetrafluoroethylene sealing rings, or metal elastic sealing rings, to adapt to sealing requirements under different environmental conditions. In addition, the connection between the pressure plate 102 and the screw 101 can adopt other fastening methods, such as snap-fit ​​or welding fixation, to improve the convenience and stability of assembly.

[0030] The cooling mechanism 2 includes a cooling barrel 201 with a die cap 205 at one end. A cooling channel 202 is formed inside the cooling barrel 201, and the screw 101 is disposed within the cooling channel 202. A cooling water inlet 203 and a cooling water outlet 204 are formed outside the cooling barrel 201. During extrusion, the screw 101 rotates, pushing the sealant towards the die head and increasing the extrusion pressure under the action of the pressure plate 102. As the main cooling component for the sealant, the cooling barrel 201's internal cooling channel 202 ensures uniform cooling of the screw 101 and the surrounding sealant. Cooling water enters the cooling barrel 201 through the cooling inlet 203 and circulates along the cooling channel 202, absorbing the heat generated during extrusion and finally discharging through the cooling water outlet 204. The die cap 205 ensures uniform molding of the sealant at the extrusion end while preventing cooling water leakage and improving cooling efficiency. This device efficiently cools the sealant through the cooling barrel 201, ensuring rapid cooling after extrusion and achieving stable molding. The design of the cooling channel 202 allows for uniform flow of the cooling medium, improving heat dissipation efficiency and preventing localized overheating or uneven cooling. The combined use of the cooling inlet 203 and cooling outlet 204 ensures continuous circulation of cooling water, improving cooling efficiency while reducing energy consumption. Furthermore, the end cap 205 ensures a uniform cross-section of the sealant during extrusion, improving product quality and reducing shrinkage and deformation caused by temperature changes.

[0031] In the above scheme, the cooling cylinder 201 can be made of a high thermal conductivity metal, such as aluminum alloy or copper, to improve cooling efficiency. The shape and layout of the cooling channel 202 can be optimized according to cooling requirements, such as using a spiral channel or multi-layer cooling flow channel design to enhance the cooling effect. The cooling medium can be water, cooling oil, or other cryogenic fluids to suit different sealant materials and production process requirements. In addition, the positions of the cooling inlet 203 and cooling return outlet 204 can be adjusted according to actual installation requirements to optimize the hydrodynamic characteristics of the cooling system and improve overall cooling performance.

[0032] Cooling inlet 203 is connected to cooling channel 202, and cooling return outlet 204 is also connected to cooling channel 202. The direct connection between cooling inlet 203 and cooling channel 202 allows cooling medium (such as cooling water or other coolant) to smoothly enter and flow along a predetermined flow path. As the cooling medium flows through cooling channel 202, it absorbs the heat generated during sealant extrusion, thereby reducing the sealant's temperature and ensuring it is extruded and molded under appropriate temperature conditions. After heat exchange, the cooling medium is discharged through cooling return outlet 204, creating a stable circulation flow in the cooling system. This design ensures that the cooling medium efficiently removes heat, improves cooling uniformity, avoids localized overcooling or overheating, and guarantees the extrusion quality and molding effect of the sealant. Through the rational layout of cooling inlet 203 and cooling return outlet 204, this device achieves efficient circulation of the cooling medium, improves heat dissipation efficiency, ensures the sealant maintains a suitable temperature during extrusion, and prevents molding defects caused by excessive fluidity due to high temperatures or uneven cooling. In addition, this structure can effectively reduce the loss of cooling medium, improve energy utilization, reduce production costs, and enhance the stability and service life of the equipment.

[0033] In the above scheme, the shape and size of the cooling channel 202 can be optimized according to cooling requirements, such as adopting a spiral, annular, or multi-layer channel structure to improve the flow efficiency and cooling effect of the cooling medium. The relative positions of the cooling inlet 203 and the cooling outlet 204 can be adjusted, such as adopting a diagonal or layered arrangement, to optimize the flow path of the cooling medium and improve cooling uniformity. In addition, the cooling medium can be selected from low-temperature water, cooling oil, or other high-efficiency heat exchange media according to actual needs to adapt to different sealant materials and production processes. The cooling system can also integrate temperature monitoring and control devices to achieve intelligent temperature control, further improving production efficiency and product quality.

[0034] A dispensing port 104 is provided at the bottom of the cooling barrel 201. Driven by the screw 101, the sealant is conveyed downwards along the cooling channel 202 inside the cooling barrel 201 and gradually cooled by the cooling barrel 201 to reach a suitable extrusion temperature. After flowing through the end of the cooling channel 202, the sealant is extruded through the dispensing port 104 at the bottom of the cooling barrel 201, thus achieving a continuous and efficient sealant extrusion process. The design of the dispensing port 104 ensures that the sealant flows out evenly, avoiding extrusion instability caused by uneven flow resistance or temperature gradients. This device, by providing the dispensing port 104 at the bottom of the cooling barrel 201, allows the sealant to be discharged smoothly, optimizes the extrusion path, and improves production efficiency. Simultaneously, the sealant is fully cooled inside the cooling barrel 201 before being extruded through the dispensing port 104, which reduces deformation caused by high temperatures and improves molding accuracy. In addition, this design helps control the dispensing rate, ensuring uniform quality of the extruded sealant, avoiding flow rate fluctuations or clogging issues, and further improving production stability.

[0035] In the above scheme, the shape and size of the dispensing nozzle 104 can be optimized according to the flow characteristics of the sealant and production requirements, such as using a circular, rectangular, or other special cross-section to meet the molding requirements of different sealant materials. The dispensing nozzle 104 can be equipped with an adjustment device, such as a replaceable nozzle or flow control valve, to adjust the dispensing rate according to production needs. Furthermore, the position of the dispensing nozzle 104 can also be optimized according to different production processes, such as using a multiple dispensing nozzle layout to adapt to multi-outlet extrusion processes, improving production efficiency and material utilization. Simultaneously, a vacuum-assisted system or pressure regulating device can be combined to further optimize extrusion quality and reduce the impact of bubbles or impurities.

[0036] The device also includes an opening and closing mechanism 3 connected to the cooling mechanism 2. The opening and closing mechanism 3 includes a connecting bracket 301 fixed to the outside of the cooling barrel 201. A movable frame 302 is mounted on the upper part of the connecting bracket 301. A shaft 303 is mounted on the movable frame 302, a positioning pin 304 is mounted on the shaft 303, a locking nut 305 is also mounted on the shaft 303, a bushing 306 is also mounted on the shaft 303, and a pin 307 is mounted on the top of the shaft 303. A groove is formed on the movable frame 302, and the pin 307 slides within the groove. The opening and closing mechanism 3 is used to enable quick assembly and disassembly of the cooling barrel 201 for maintenance or replacement of internal components of the sealant extrusion system. The connecting bracket 301, fixed to the outside of the cooling barrel 201, provides support for the entire opening and closing mechanism 3. The movable frame 302 adjusts its relative position by sliding, and the stability of the system is ensured by the insertion and locking of the shaft 303. Shaft 303 maintains smooth movement via bushing 306 and is secured in place by locking nut 305 to prevent accidental loosening. Positioning pin 304 further enhances the securing effect, ensuring the moving frame 302 remains stable during operation. Pin 307 is located within a groove in the moving frame 302 and can slide along the groove for position adjustment when needed, thereby enabling the opening and closing of the cooling barrel 201. This device, through the design of the opening and closing mechanism 3, facilitates the convenient assembly and disassembly of the cooling barrel 201, improving equipment maintenance and cleaning efficiency and reducing downtime. The coordinated use of shaft 303, positioning pin 304, and locking nut 305 ensures a secure connection of the cooling mechanism 2, preventing loosening or misalignment during operation. The sliding design of the moving frame 302 allows operators to quickly adjust the barrel position, simplifying the maintenance process and reducing the difficulty of manual operation. Simultaneously, this design improves the safety of the extruder, preventing leakage or equipment damage caused by unstable component connections.

[0037] In the above scheme, the structure of the movable frame 302 can be further optimized, such as by adopting an electric or pneumatic drive to achieve more precise and automated opening and closing operations. The fixing method of the shaft 303 can be improved to a quick-disassembly mechanism, such as spring locking or snap-fit ​​connection, to improve loading and unloading efficiency. The material of the bushing 306 can be selected from wear-resistant and high-strength materials, such as ceramics or special alloys, to enhance service life. The shape and size of the groove can be optimized according to actual needs, such as by adding a guide structure to improve sliding stability. In addition, a remote monitoring or sensor system can be added to achieve intelligent monitoring of the status of the cooling cylinder 201, improving the automation level and safety of the equipment.

[0038] A bearing 308 is externally mounted on the pin 307, and a washer 309 is fixed to the side of the pin 307. The bearing 308 on the outside of the pin 307 reduces the friction when the pin 307 slides in the groove of the moving frame 302, improving the smoothness of sliding and making the opening and closing mechanism 3 more stable and efficient during operation. The addition of the bearing 308 helps reduce mechanical wear, extends the service life of the opening and closing mechanism 3, and reduces the heat and resistance generated by friction, improving the durability of the sealant extruder in high-intensity working environments. The washer 309 is fixed to the side of the pin 307, mainly serving as a buffer and limiter, ensuring that the pin 307 maintains a suitable clearance when sliding in the groove, preventing excessive shaking or displacement, and improving structural stability. The use of the bearing 308 makes the pin 307 move more smoothly, effectively reducing jamming caused by friction and improving the ease of operation of the opening and closing mechanism 3. Because bearing 308 reduces direct contact between pin 307 and the groove of moving frame 302, wear is reduced, improving the durability and stability of the entire opening and closing mechanism 3. The addition of shim 309 effectively prevents lateral displacement of pin 307 during sliding, maintaining the accuracy of the opening and closing mechanism 3 during operation and ensuring the stable connection of cooling mechanism 2. The rolling design of bearing 308 reduces frictional noise during sliding, while the cushioning effect of shim 309 further reduces vibration caused by component shaking, improving the smoothness of equipment operation.

[0039] In the above scheme, bearing 308 can be of different types, such as deep groove ball bearings or needle roller bearings, to adapt to different load requirements. The material of pin 307 can be optimized to high-strength alloy steel or ceramic to improve wear resistance and corrosion resistance. Gasket 309 can be made of elastic material, such as rubber or silicone, to enhance the cushioning effect and reduce impact. At the same time, the position of bearing 308 can be adjusted to make its contact with pin 307 more uniform, thereby optimizing the stress distribution and improving overall performance. In addition, maintenance-free bearings or self-lubricating structures can be used to reduce the need for later maintenance and improve the automation level and reliability of the equipment.

[0040] The device also includes a locking mechanism 4 mounted on the opening and closing mechanism 3. The locking mechanism 4 includes a locking pin 401 fixed to the end cap 205, a locking rod 402 fixed to the locking pin 401, a pull plate 403 fixed to the locking rod 402, and a locking head 404 fixed to one end of the locking rod 402. The main function of the locking mechanism 4 is to ensure the stability of the opening and closing mechanism 3 during operation and to prevent accidental loosening or displacement of the cooling cylinder 201. The locking pin 401, fixed to the end cap 205, provides fixed support for the entire locking structure. The locking rod 402, through its connection with the locking pin 401, reliably secures the opening and closing mechanism 3. The pull plate 403 enhances the force distribution of the locking rod 402, preventing loosening or damage due to uneven force. The locking head 404 is located at one end of the locking lever 402 and can be locked or released by rotation, push-pull, or other means, allowing the opening and closing mechanism 3 to be quickly disassembled or fixed. This design ensures the stable operation of the sealant extruder and improves the safety and ease of operation of the equipment. The addition of the locking mechanism 4 increases the fixing strength of the opening and closing mechanism 3, preventing loosening due to vibration or pressure changes and ensuring the stability of the sealant extrusion process. The cooperation between the locking lever 402 and the locking head 404 achieves quick locking and releasing functions, simplifying the operation of the opening and closing mechanism 3 and improving maintenance efficiency. The addition of the pull plate 403 optimizes the force distribution, reduces the situation of excessive force at a single point, and extends the service life of the locking mechanism 4. The fixing method of the locking pin 401 and the orifice end cap 205 ensures the overall structural integrity, avoids safety hazards caused by equipment loosening, and improves the reliability of equipment operation.

[0041] In the above scheme, the locking lever 402 can adopt different types of locking structures, such as threaded fastening, spring locking, or quick-release buckles, to adapt to different operational needs. The locking head 404 can be selected from knob-type, lever-type, or automatic locking mechanisms according to different usage scenarios to improve the convenience and security of locking. The shape and material of the pull plate 403 can be optimized, such as using high-strength alloys or corrosion-resistant materials, to enhance durability. Furthermore, the position and installation method of the locking pin 401 can be adjusted according to the structure of the barrel 201 to optimize the overall design of the equipment and improve the convenience of installation and maintenance.

[0042] The sealant is discharged in a thin sheet structure, which increases the contact area with air and facilitates rapid cooling. Therefore, a high-pressure extrusion method is designed, consisting of a screw 101, a sealant pressure plate 102, a sealing ring 103, fixing bolts, a discharge port 104, a cooling barrel 201, and a nozzle end cap 205. The pressure plate 102 is mounted to the head of the screw 101 by the fixing bolts. The sealant is discharged from the discharge port 104 through a sealed cavity formed by the cooling barrel 201 and the nozzle end cap 205. The sealing ring 103 prevents leakage from the back of the pressure plate. The diameter of the pressure plate 102 is larger than that of the screw 101. When the screw 101 rotates, the speed at the edge of the pressure plate 102 is greater than that of the bolt, facilitating the generation of high pressure at this location. The discharge port 104 and the die head cavity form two discharge ports, allowing two sheets of sealant to be discharged simultaneously during production, improving production efficiency.

[0043] The sealant is discharged in sheet form from the outlet 104 through a closed channel consisting of a cooling cylinder 201, a nozzle cover 205, and a screw 101. The cooling cylinder 201 and nozzle cover 104 have internal cooling channels that use cooling water as a medium to cool themselves. Due to the metallic properties of the cooling cylinder 201 and nozzle cover 104, they absorb the heat energy of the high-temperature sealant through heat conduction, achieving a cooling function. The cooling cylinder 201 has an internal spiral cooling channel; circulating water enters from the cooling inlet 203, passes through the spiral cooling channel 202, and exits through the cooling return outlet 204, carrying away the heat from the high-temperature sealant. The cooling cylinder 201 also has an internal cavity-type cooling channel 202; circulating water enters from the cooling inlet 203, passes through the cavity-type cooling channel, and exits through the cooling return outlet 204, carrying away the heat from the high-temperature sealant. The end cap 205 has an internal spiral cooling channel 202. Circulating water enters from the cooling inlet 203, passes through the spiral cooling channel, and exits through the cooling return inlet 204, carrying away the heat from the high-temperature sealant. In summary, the sealant is contained within a closed channel formed by the cooling barrel 201, the end cap 205, and the screw 101, all of which are circulated with cooling water, achieving water-cooled sealant.

[0044] The connecting bracket 301 is bolted to the upper part of the cooling cylinder 201, and the movable frame 302 is also bolted to the upper part of the connecting bracket 301. The moving mechanism consists of a shaft 303, a locating pin 304, a locking nut 305, a bushing 306, a pin 307, a bearing 308, a washer 309, and fixing bolts. When this mechanism is open, it presses... Figure 1 The arc-shaped track movement can open the end cap 205 to its maximum position. When the end cap 205 is closed, due to the sealant on the bolt rod, a large internal pressure is generated, and the end cap 205 will automatically open. Therefore, this invention designs a locking mechanism to lock the end cap 205 and keep it in the closed state.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
