Description

TECHNICAL FIELD

[0002] In the field of tire manufacturing, the pouring forming process has become one of the important methods for producing high-performance tires such as low rolling resistance and high wear resistance, because it can accurately control material distribution and structure forming. The process injects pre-prepared tire raw materials into a precision mold, and after curing, a tire product with specific performance is formed.

[0003] However, in the actual production process, due to the fast curing characteristics of tire raw materials (such as high molecular materials such as polyurethane), material adhesion and accumulation inevitably occur around the discharge port of the pouring head. This adhesion not only changes the effective cross-sectional area of the discharge port, causing deviations in the subsequent pouring process, but also causes uneven material distribution, seriously affecting the dimensional accuracy and performance consistency of the tire product. To solve this problem, the existing technology usually uses a rotating scraper at the bottom of the pouring head discharge port to scrape off the material adhering around the discharge port, or a hydraulic cylinder is provided inside the head, and the piston rod extends into the discharge channel. After pouring is completed, the piston is pushed to forcibly discharge the residual material to avoid solidification blockage.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The present invention provides an embodiment: please refer to Figure 1-Figure 7 A casting device for low rolling resistance and high wear-resistant tire production includes a material storage pump structure, a quantitative structure and a casting structure. The material storage pump structure includes a storage barrel 1 and a feeding component 2. A stirring structure 6 is provided in the middle of the inner cavity of the storage barrel 1. The stirring structure 6 is an existing technology. It only needs to be able to achieve stable stirring of the casting raw materials for low rolling resistance and high wear-resistant tire production and to be able to adjust the stirring speed according to demand. It will not be elaborated here.

[0028] The inner cavity of the storage barrel 1 is movably connected with a scraper 7, which contacts the inner wall of the storage barrel 1, and the scraper 7 is movably connected to the top of the inner cavity of the storage barrel 1 through a rotating ring 25. The rotating ring 25 is movably connected to the stirring end of the stirring structure 6 through a support rod 26. An electromagnet 24 is provided on the support rod 26. When the electromagnet 24 is in an energized state, the electromagnet 24 and the stirring end of the stirring structure 6 are in a state of magnetic attraction. At this time, when the stirring structure 6 is working, the scraper 7 can be driven to rotate by the support rod 26 and the rotating ring 25. The scraper 7 can scrape off the tire casting raw materials adhering to the inner wall of the storage barrel 1. The present application adopts an intermittent working mode of the scraper 7, which can slow down the wear of the scraper 7 and the inner wall of the storage barrel 1 and extend the service life of the scraper 7. The model of the electromagnet 24 and the material of the stirring end of the stirring structure 6 can be selected according to demand and are not limited here.

[0029] The feeding end of the material conveying assembly 2 is connected with the discharging end of the storage cylinder 1, and the discharging end of the material conveying assembly 2 is connected with the feeding end of the metering structure. When the material conveying assembly 2 works, the tire pouring raw material in the storage cylinder 1 can be pumped into the metering structure. The material conveying assembly 2 is a prior art and can realize stable conveying of the tire pouring raw material, and thus will not be described here. The discharging end of the material conveying assembly 2 is movably connected with a material conveying pipe 29. The bottom end of the material conveying pipe 29 is provided with an electric ball valve 9. A second vibrator 10 is arranged on the valve plate of the electric ball valve 9. When the valve plate of the electric ball valve 9 is in a horizontal state, the bottom of the valve plate and the top of the inner cavity of the metering cylinder are in a mutually flush state. Through the arrangement of the second vibrator 10, when the second vibrator 10 works, the vibration generated by the second vibrator 10 can accelerate the flow of the tire pouring raw material, so that the raw material flows into the metering structure.

[0030] When the present application is used for the first time, the staff needs to use the existing vacuum pump and other vacuumizing equipment to perform vacuumizing treatment on the metering structure, so as to avoid that the air existing in the metering structure affects the quality of the tire being poured.

[0031] The middle part of the side wall of the material conveying assembly 2 and the middle part of the cylinder wall of the storage cylinder 1 are both provided with flow channels, the two flow channels are in a communicating state, and a heat preservation flow channel 8 is formed. One end of the heat preservation flow channel 8 is provided with a first liquid inlet end 27, and the other end of the heat preservation flow channel 8 is provided with a first liquid outlet pipe 28. In use, the medium fluid for heat preservation of the tire pouring raw material flows in the heat preservation flow channel 8, so as to realize heat preservation of the tire pouring raw material.

[0032] The metering structure includes a metering cylinder and a first heat preservation sleeve 3 wrapped outside the metering cylinder. The side wall of the first heat preservation sleeve 3 is a hollow structure. One end of the inner cavity of the side wall of the first heat preservation sleeve 3 is provided with a second liquid inlet pipe 15, and the other end of the inner cavity of the side wall of the first heat preservation sleeve 3 is provided with a second liquid outlet pipe 14. In use, the medium fluid for heat preservation of the tire pouring raw material flows in the inner cavity of the first heat preservation sleeve 3, so as to realize heat preservation of the tire pouring raw material.

[0033] The metering cylinder includes a fixed cover 12 connected with the material conveying pipe 29 and a cylinder body 13 detachably connected with the bottom end of the fixed cover 12. The inner wall of the cylinder body 13 is uniformly provided with a third vibrator 22. The first heat preservation sleeve 3 is connected with the outer side wall of the cylinder body 13. When the third vibrator 22 works, vibration can be generated in the inside of the metering cylinder, so as to improve the speed of uniform distribution of the fluid in the metering cylinder, facilitate separation of the fluid adhered to the inner wall of the metering cylinder from the inner wall of the metering cylinder, and reduce pouring quantity error. The inner wall of the cylinder body 13 is provided with a pressure sensor. The controller of the present application can indirectly judge the material quantity in the metering cylinder according to the monitoring result of the pressure sensor.

[0034] The discharge end of the material storage and pumping structure is equipped with a first drive mechanism 11. When in operation, this mechanism drives the metering cylinder, which in turn drives the feed pipe 29. The rotation of the metering cylinder and feed pipe 29 allows any tire casting fluid adhering to the inner wall of the metering cylinder and the bottom of the valve plate to fall off, reducing casting volume errors and ensuring tire production quality. This first drive mechanism 11 is conventional technology and ensures stable rotation and precise positioning of the metering cylinder.

[0035] From the above description, it can be seen that the present application utilizes a quantitative structure to achieve quantitative measurement of the tire pouring amount, which can avoid deviations in the tire pouring amount and improve the tire pouring quality. In addition, the cylinder can be replaced, so that the present application can adapt to a variety of tires, thereby improving the adaptability of the present application.

[0036] The inner wall of the quantitative structure is provided with an anti-stick coating. The material of the anti-stick coating can be set according to needs and is not limited here. The bottom of the quantitative structure's inner cavity is inclined. The discharge end of the quantitative structure is located at the lower end of the bottom of the quantitative structure's inner cavity. The feed end of the pump 4 is in a state of movable connection with the discharge end of the quantitative structure. This arrangement facilitates the pumping of tire casting materials by the pump 4. The pump 4 is a prior art and can achieve stable delivery of tire casting materials.

[0037] The feed end of the casting structure is connected to the discharge end of the quantitative structure through a pump 4, and the pump 4 is connected to the feeding component 2. The casting structure includes a casting head 18 connected to the discharge end of the pump 4. Under the action of the pump 4, the tire casting raw materials can be pumped into the casting head 18. The outer wall of the casting head 18 is wrapped with a second insulation sleeve 5. The side wall of the second insulation sleeve 5 is a hollow structure. A third liquid inlet pipe is provided at one end of the inner cavity of the side wall of the second insulation sleeve 5, and a third liquid outlet pipe is provided at the other end of the inner cavity of the side wall of the second insulation sleeve 5. The medium fluid for keeping the tire casting raw materials warm flows in the inner cavity of the side wall of the second insulation sleeve 5, thereby realizing the insulation of the raw materials in the casting head 18 and reducing the probability of the raw materials clogging the casting head 18, which is convenient for the use of this application.

[0038] The discharge end of the pouring machine head 18 is movably connected to a discharge pipe 20, and an anti-sticking tube 21 is provided on the inner wall of the discharge pipe 20. A first vibrator 23 is provided on the anti-sticking tube 21, and a shock-absorbing structure is provided between the discharge pipe 20 and the anti-sticking tube 21. The shock-absorbing structure can be set as needed to avoid the vibration of the first vibrator 23 from affecting the discharge pipe 20. There is no restriction here. A second drive structure 19 is provided on one side of the pouring machine head 18. The second drive structure 19 can drive the discharge pipe 20 to rotate. The second drive structure 19 is an existing technology and only needs to be able to achieve stable rotation and precise positioning of the discharge pipe 20. During the pouring process, the discharge pipe 20 can rotate and the first vibrator 23 can vibrate. Under the action of centrifugal force and vibration, the probability of raw materials adhering to the discharge pipe 20 and the anti-sticking pipe 21 is reduced, thereby reducing the probability of clogging of the discharge pipe 20 and the anti-sticking pipe 21 and the frequency of cleaning. The inner wall of the anti-sticking pipe 21 and the outer wall of the discharge pipe 20 are both provided with an anti-stick coating. The material of the anti-stick coating can be selected according to needs and is not limited here. The use of the anti-stick coating can further reduce the probability of material sticking to the discharge end of the pouring structure.

[0039] A cleaning structure is provided on one side of the pouring machine head 18 . The cleaning structure includes a cleaning scraper 17 adapted to the discharge pipe 20 and the anti-sticking pipe 21 . The cleaning scraper 17 is connected to the pouring machine head 18 via a lifting and translational structure 16 .

[0040] The cleaning scraper 17 is U-shaped. The inner wall of one vertical end of the cleaning scraper 17 connected to the lifting and translation structure 16 is adapted to the outer wall of the discharge pipe 20, the inner wall of the other vertical end of the cleaning scraper 17 is adapted to the inner wall of the anti-sticking tube 21, and the horizontal end of the cleaning scraper 17 is adapted to the bottom of the discharge pipe 20. Under the action of the lifting and translation structure 16, one vertical end of the cleaning scraper 17 can be closely fitted with the outer wall of the discharge pipe 20, the other vertical end of the cleaning scraper 17 can be closely fitted with the inner wall of the anti-sticking tube 21, and the horizontal end of the cleaning scraper 17 is closely fitted with the bottom of the discharge pipe 20 and the bottom of the anti-sticking tube 21. At this time, when the discharge pipe 20 rotates, the discharge pipe 20 and the anti-sticking tube 21 move relative to the cleaning scraper 17. The cleaning scraper 17 can scrape off the tire casting material adhering to the discharge end of the casting structure, thereby cleaning the discharge end of the casting structure and avoiding downtime during the cleaning process.

[0041] From the above description, it can be seen that the discharge pipe 20 and the anti-sticking pipe 21 form a pouring discharge pipe. The present application reduces the probability of raw material adhesion by rotating and vibrating the pouring discharge pipe, thereby reducing the probability of clogging of the pouring discharge pipe, ensuring the uniformity of raw material distribution, and has a self-cleaning function. The cleaning scraper 17 is used to automatically clean the pouring discharge pipe, reducing the probability of shutdown and ensuring tire pouring efficiency.

[0042] The electrical components involved in this application are all existing technologies. Technicians in this field can select appropriate models of electrical components according to their needs. No restrictions or detailed descriptions are made here. Technicians in this field understand their connection methods. Through these people, all electrical components in this application are connected to their corresponding power supplies through wires, and according to actual conditions, appropriate controllers are selected to meet control requirements. Please refer to the description below for specific connections and control sequences. The electrical connections between the electrical components are completed in a sequential working order. The detailed connection methods are well known in this field. The following mainly introduces the working principles and processes, and no further explanation of electrical control is given.

[0043] In summary: when the low rolling resistance and high wear-resistant tire production casting device is used, low rolling resistance and high wear-resistant tire production casting raw materials are placed in the storage barrel 1. During the storage of the raw materials in the storage barrel 1, the stirring structure 6 stirs the raw materials, and the medium fluid for keeping the raw materials warm flows in the insulation flow channel 8 to achieve insulation of the raw materials. The raw materials in the storage barrel 1 can be transported to the quantitative structure under the action of the feeding component 2. The controller of this application indirectly determines the amount of raw materials in the quantitative cylinder based on the monitoring results of the pressure sensor. When the quantitative cylinder is filled, the feeding component 2 stops working, and the electric ball valve 9 works. The feed pipe 29 is in a closed state, and the pump 4 is working. Under the action of the pump 4, the raw materials in the metering cylinder can be pumped into the pouring machine head 18 and discharged into the tire pouring mold through the pouring discharge pipe. During the pouring process, the metering cylinder rotates, the second drive structure 19 drives the pouring discharge pipe to rotate, and the first vibrator 23 rotates to reduce the probability of raw material adhesion, reduce the deviation of the tire pouring amount, and ensure the quality of tire pouring molding. In the final stage of the tire pouring process, the metering cylinder rotates. After the pouring is completed, the pump 4 stops working and the feed assembly 2 works. During the replacement process of the tire pouring mold, the quantitative replenishment of raw materials is achieved.
