Description

Technical Field

[0001] The invention relates to the field of automobile sealing strip processing, and more specifically to an automobile sealing strip vulcanizing device. Background Art

[0002] Automobile sealing strips are rubber or plastic products installed in different parts of the car to fill the gaps between body parts. They are one of the important parts of the car and are widely used in doors, windows, bodies, seats, sunroofs, engine boxes and trunks. In order to improve the physical and mechanical properties of sealing strips, such as elasticity, heat resistance, wear resistance and tensile strength, they need to be vulcanized during the production process. Vulcanization refers to the process of cross-linking linear polymer chains in rubber or synthetic materials to form a three-dimensional network structure through a specific chemical process.

[0003] There are various ways to vulcanize sealing strips. The common methods are compression vulcanization, continuous vulcanization and roller vulcanization. Continuous vulcanization includes microwave vulcanization, salt bath vulcanization, hot air vulcanization, oven vulcanization and steam vulcanization. For oven vulcanization, it means that the sealing strip formed into a predetermined shape after extrusion is placed in a temperature-controlled oven, and hot air is used to heat the rubber material to cause a cross-linking reaction, thereby achieving the vulcanization process.

[0004] However, during the oven vulcanization process, multiple sealing strips are usually dispersed and placed on a tray in the oven, and the tray is rotated to achieve uniform heating. However, this rotation will cause the sealing strips to be swung and contact each other, causing entanglement and adhesion problems, which not only increases the manual processing time required to separate the sealing strips, but also causes the surface of the sealing strip to tear or be damaged, seriously affecting the product quality. In addition, since the side of the sealing strip that contacts the tray cannot be fully exposed to hot air, this will cause uneven heating, which in turn affects the uniformity of vulcanization and reduces the appearance quality and performance of the sealing strip. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a vulcanizing device for automobile sealing strips, which can separate the sealing strips and automatically roll the sealing strips during the vulcanization process, so that the entire sealing strip can be fully exposed to hot air, and the problems of entanglement and adhesion between the sealing strips due to mutual contact can be avoided, which can effectively improve the uniformity of heating and the efficiency of vulcanization, thereby effectively improving the appearance quality and performance of the sealing strips.

[0012] Furthermore, an exhaust port 1 is evenly opened on one side of the inner cavity of the fixed cylinder close to the large gear, and an exhaust port 2 is evenly opened on the other side of the inner cavity of the fixed cylinder. Each group of the exhaust port 1 and the exhaust port 2 are connected to the inner cavity of the exhaust cavity. A connected air intake port 1 is opened on the adjacent side of the large gear and the fixed cylinder, and an air intake port 2 is opened on the other side wall of the fixed cylinder. The air intake port 1 and the air intake port 2 are both connected to the inner cavity of the fixed cylinder.

[0013] Furthermore, a number of connecting plates one matching the number of the rollers are evenly fixedly installed on one side of the rotating plate close to the fixed cylinder, and each group of the connecting plates one evenly surrounds the outer side of the fixed cylinder.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) In this scheme, the teeth and the large gear are coordinated. While the rotating plate drives each group of rollers to move in a circular motion, each group of rollers will rotate on its own, which can drive the sealing strip in its inner cavity to roll continuously, so that the entire sealing strip can be fully exposed to the hot air, which can effectively improve the uniformity of heating and the efficiency of vulcanization, thereby effectively improving the appearance quality and performance of the sealing strip. At the same time, the sealing strips can be separated by each group of rollers to prevent the sealing strips from contacting each other and causing entanglement and adhesion, thereby avoiding the problem of entanglement and adhesion that leads to increased manual processing time and tearing and damage on the surface of the sealing strip, thereby effectively improving the quality of the sealing strip.

[0021] (2) In this solution, the pinion and the ring gear are coordinated. The rotating plate drives each group of ventilation pipes to move in a circular motion, and at the same time, the fan blades rotate rapidly to absorb the hot gas in the oven cavity and then blow it into the drum through the rotating pipe, thereby playing a ventilation role. It can effectively improve the fluidity of the hot gas in the oven cavity and achieve good hot gas circulation in the oven, ensuring temperature uniformity and ensuring that the airflow can evenly cover the entire sealing strip, thereby effectively improving the vulcanization effect, and then effectively improving the quality and performance of the sealing strip.

[0022] (3) This solution drives the reciprocating screw to rotate by the rotating plate, so that the piston plate can move back and forth left and right in the inner cavity of the fixed cylinder. The piston plate will inhale air through the corresponding air inlet 1 or air inlet 2, and exhaust air through the corresponding air outlet 1 or air outlet 2. The gas will be discharged to the outside through each group of exhaust holes and blown onto the groups of rollers surrounding the outside, thereby achieving uniform heating of the inside of each group of rollers. The situation where the temperature of the inside and outside of each group of rollers is uneven due to too many rollers can be avoided, thereby effectively improving the effect of uniform heating vulcanization, and further effectively improving the efficiency of vulcanization.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 6 , a vulcanizing device for automobile sealing strips, comprising an oven 1, a rotating plate 2 is arranged on one side of the inner cavity of the oven 1, and the rotating plate 2 is rotatably mounted on the inner cavity wall of the oven 1;

[0033] Also includes:

[0034] A rolling assembly, the rolling assembly includes ventilation pipes 3 uniformly surrounding the outer side of the rotating plate 2, each group of ventilation pipes 3 is fixedly installed on the rotating plate 2, one end of each group of ventilation pipes 3 is rotatably installed with a rotating pipe 4, the other end of each group of rotating pipes 4 is rotatably installed with a roller 5, the outer side of each group of rollers 5 is uniformly provided with through holes 9, and each group of through holes 9 is connected to the inner cavity of the adjacent rollers 5, the other end of the outer side of each group of rollers 5 is uniformly installed with teeth 8, a large gear 6 is provided between each group of rollers 5, the large gear 6 is meshed with the adjacent teeth 8, a support rod 7 is fixedly installed on one side of the large gear 6, and the support rod 7 is fixedly installed in the inner cavity of the support rod 7, and a ventilation assembly is provided in each group of ventilation pipes 3.

[0035] The ventilation assembly includes a rotating rod 10 rotatably installed in the inner cavity of the ventilation pipe 3, and each group of rotating rods 10 is fixedly installed with a fan blade 11 at one end close to the adjacent rotating pipe 4. A gear ring 12 is fixedly installed on the inner cavity wall of the oven 1, and the inner cavity of the gear ring 12 is evenly meshed with small gears 13 matching the number of ventilation pipes 3. Each group of small gears 13 is fixedly installed on one end of the adjacent rotating rod 10, and a motor 14 is fixedly installed on the outside of the oven 1, and the output end of the motor 14 is fixedly installed on the rotating plate 2.

[0036] First, the sealing strip extruded by the extruder will form a predetermined shape, and the sealing strip at this time will be inserted into the inner cavity of the roller 5 through the left end of the roller 5. After the sealing strip is placed in each group of rollers 5, the oven 1 is turned on, and the oven 1 will heat its inner cavity. The hot gas will enter the inner cavity of each group of rollers 5 through each group of through holes 9, so that the sealing strip in the roller 5 can be heated and vulcanized. The motor 14 is turned on, and the output end of the motor 14 will drive the rotating plate 2 to rotate. When the rotating plate 2 rotates, it will drive the groups of ventilation pipes 3 thereon to move synchronously. Each group of ventilation pipes 3 will drive each group of rollers 5 to perform circular motion through the adjacent rotating tubes 4. The circular motion of each group of rollers 5 will perform circular motion around the outer side of the large gear 6, which plays a role in uniform heating, and can effectively improve the uniformity of vulcanization of the sealing strip in the roller 5. Through the setting of each group of teeth 8 on each group of rollers 5, each group of rollers 5 will move around the large gear 6. The wheel 6 rotates on the large gear 6 while performing circular motion. At this time, each group of rollers 5 can rotate on the ventilation pipe 3 through the rotating tube 4 while performing circular motion in the inner cavity of the oven 1. The rollers 5 drive the sealing strips in the inner cavity to continuously roll while rotating, so that the entire sealing strip is fully exposed to the hot air, which can effectively improve the uniformity of heating and the efficiency of vulcanization, thereby effectively improving the appearance quality and performance of the sealing strips. At the same time, a sealing strip is placed in each group of rollers 5 to separate the sealing strips, which can prevent the sealing strips from contacting each other and causing entanglement and adhesion, and avoid the situation where the entanglement and adhesion problems lead to increased manual processing time and tearing damage on the surface of the sealing strip, thereby effectively improving the quality of the sealing strip. At the same time, the rollers 5 can be used to place sealing strips of different diameters, thereby improving the adaptability range.

[0037] When the rotating plate 2 drives each group of ventilation pipes 3 to make circular motion, each group of ventilation pipes 3 will drive the rotating rod 10 therein to move synchronously, and the rotating rod 10 will drive the pinion 13 thereon to rotate in the inner cavity of the gear ring 12. When the pinion 13 rotates, the fan blade 11 will be driven to rotate synchronously through the rotating rod 10. Through the cooperation of the pinion 13 and the gear ring 12, each group of ventilation pipes 3 can make circular motion while the pinion 13 can rotate rapidly in the inner cavity of the gear ring 12, so that the fan blade 11 can continuously absorb the oven 1 through the right end of the ventilation pipe 3. The hot gas in the inner cavity is then blown into the drum 5 through the rotating tube 4. The hot gas will flow to the left and be discharged in the inner cavity of the drum 5, and will also be discharged through each group of through holes 9. Since the sealing strip is hollow, the hot gas will also flow to the left and be discharged from the inner hollow of the sealing strip, which plays a role in ventilation. It can effectively improve the fluidity of the hot gas in the inner cavity of the oven 1, and realize good hot gas circulation in the oven 1, ensuring the uniformity of temperature, and at the same time ensuring that the airflow can evenly cover the entire sealing strip, thereby effectively improving the vulcanization effect, and then effectively improving the quality and performance of the sealing strip.

[0038] like Figure 3 and Figure 4 As shown, a reciprocating screw 15 is fixedly installed on one side of the rotating plate 2 close to the large gear 6, and the other end of the reciprocating screw 15 is rotatably installed with the large gear 6. The reciprocating screw 15 is located between the rotating plate 2 and the center of the large gear 6. A fixed cylinder 16 is rotatably installed on the outer side of the reciprocating screw 15. The fixed cylinder 16 is fixedly installed on one side of the large gear 6. A piston plate 17 is slidably installed in the inner cavity of the fixed cylinder 16. The piston plate 17 is threadedly installed with the reciprocating screw 15. An exhaust chamber 20 is opened in the outer wall of the fixed cylinder 16, and exhaust holes 23 are evenly opened on the outer wall of the fixed cylinder 16. Each group of exhaust holes 23 is connected to the inner cavity of the exhaust chamber 20.

[0039] An exhaust port 1 21 is evenly provided on one side of the inner cavity of the fixed cylinder 16 close to the large gear 6, and an exhaust port 2 22 is evenly provided on the other side of the inner cavity of the fixed cylinder 16. Each group of exhaust ports 1 21 and exhaust ports 2 22 are connected to the inner cavity of the exhaust cavity 20. A connected air intake port 1 18 is provided on the adjacent side of the large gear 6 and the fixed cylinder 16, and an air intake port 2 19 is provided on the other side wall of the fixed cylinder 16. Both the air intake port 18 and the air intake port 2 19 are connected to the inner cavity of the fixed cylinder 16.

[0040] The inner cavities of the air inlet 18, the air inlet 2 19, the exhaust port 1 21 and the exhaust port 2 22 are all installed with a one-way valve. The gas in the inner cavity of the fixed cylinder 16 can only be inhaled through the air inlet 18 and the air inlet 2 19, and exhausted through the exhaust port 1 21 and the exhaust port 2 22. The output end of the motor 14 drives the rotating plate 2 to rotate, and at the same time drives the reciprocating screw 15 to rotate synchronously. When the reciprocating screw 15 rotates, it drives the piston plate 17 to move back and forth left and right in the inner cavity of the fixed cylinder 16. When the piston plate 17 moves to the right in the inner cavity of the fixed cylinder 16, the piston plate 17 absorbs the gas in the inner cavity of the oven 1 through the air inlet 18 and discharges it into the inner cavity of the fixed cylinder 16, and is placed on the left side of the piston plate 17. At the same time, the movement of the piston plate 17 to the right will squeeze the gas in the inner cavity of the fixed cylinder 16 on its right side and discharge it into the inner cavity of the exhaust chamber 20 through the exhaust port 22. When the plate 17 moves to the left in the inner cavity of the fixed cylinder 16, the piston plate 17 will absorb the gas in the inner cavity of the oven 1 through the suction port 2 19 and discharge it into the inner cavity of the fixed cylinder 16, and be placed on the right side of the piston plate 17. At the same time, the movement of the piston plate 17 to the left will squeeze the gas in the inner cavity of the fixed cylinder 16 on its left side through the exhaust port 1 21 and discharge it into the inner cavity of the exhaust cavity 20. At this time, during the reciprocating movement of the piston plate 17 left and right, the inner cavity of the exhaust cavity 20 can be continuously exhausted. The gas in the inner cavity of the exhaust cavity 20 will be discharged to the outside through each group of exhaust holes 23 and blown onto each group of rollers 5 moving around the outside of the fixed cylinder 16, thereby achieving uniform heating of the inner side of each group of rollers 5. The situation that the temperature inside and outside of each group of rollers 5 is uneven due to too many rollers 5 can be avoided, thereby effectively improving the effect of uniform heating vulcanization, and further effectively improving the efficiency of vulcanization.

[0041] like Figure 4 and Figure 6 As shown, a number of connecting plates 24 matching the number of rollers 5 are evenly fixedly installed on one side of the rotating plate 2 close to the fixed cylinder 16 , and each group of connecting plates 24 evenly surrounds the outer side of the fixed cylinder 16 .

[0042] Each group of connecting plates 24 is fixedly mounted with an elastic rod 25 on one side away from the fixed cylinder 16 , and each group of elastic rods 25 is fixedly mounted with a fixed ball 26 on the other end. Semicircular grooves 27 matching the adjacent fixed balls 26 are evenly opened on the outer wall of each group of rollers 5 .

[0043] Limiting plates 28 are provided on both sides of each group of fixed balls 26 , and each group of limiting plates 28 is fixedly installed with the adjacent connecting plate 1 24 .

[0044] The output end of the motor 14 drives the rotating plate 2 to rotate, and at the same time drives each group of connecting plates 24 to rotate synchronously. The rotation of each group of connecting plates 24 can achieve uniform stirring of the hot gas discharged from each group of exhaust holes 23 in a fixed direction, which can effectively improve the temperature uniformity between each group of rollers 5, thereby achieving a uniform heating and vulcanization effect;

[0045] When the rotating plate 2 drives each group of connecting plates 1 24 to move in a circular motion, the roller 5 moves in a circular motion with the connecting plate 1 24, but the roller 5 rotates while moving in a circular motion. When the roller 5 rotates to make the semicircular groove 27 move to the outside of the fixed ball 26, the fixed ball 26 is squeezed by the roller 5 and the elastic rod 25 is bent. When the next group of semicircular grooves 27 on the outside of the roller 5 moves to the outside of the fixed ball 26, under the action of the elastic rod 25, the elastic rod 25 returns to its initial state and drives the fixed ball 26 to fit into the semicircular groove 27. In the inner cavity of the semicircular groove 27, the fixed ball 26 can reciprocately impact the inner cavity of the semicircular groove 27 during the rotation of the drum 5, so that the drum 5 continues to vibrate. When the drum 5 rotates and drives the inner sealing strip to roll, it vibrates at the same time, which can reduce the adhesion between the sealing strip and the inner cavity of the drum 5, which helps the sealing strip to turn over more smoothly. At the same time, it can promote a slight relative movement between the sealing strip and the inner wall of the oven 1, and help to better transfer heat to various parts of the sealing strip, improve the uniformity of heating, and further reduce the risk of adhesion during the vulcanization process;

[0046] By setting the limiting plate 28, the fixed ball 26 can be limited, so that the fixed ball 26 continues to move on the path of the semicircular groove 27 to prevent it from deviating, playing a role of limiting guide, and can effectively maintain the frequency of the fixed ball 26 hitting the semicircular groove 27, thereby improving the good vibration effect.

[0047] like Figure 2 and Figure 6 As shown, a second connecting plate 29 is provided on a side of each group of rollers 5 away from the fixed cylinder 16 , and each group of second connecting plates 29 is fixedly installed with the adjacent ventilation pipe 3 .

[0048] A movable door 30 is hingedly mounted on one side of the oven 1 close to the support rod 7 .

[0049] Each group of rollers 5 is evenly wound around the outside of the fixed cylinder 16, and each group of elastic rods 25 is in a compressed state in the initial state.

[0050] The output end of the motor 14 drives the rotating plate 2 to rotate, and at the same time drives the connecting plate 2 29 thereon to move synchronously through each group of ventilation pipes 3. Each group of connecting plates 29 will perform circular motion in the inner cavity of the oven 1 and the outer sides of each group of rollers 5, so as to stir the gas in the inner cavity of the oven 1, so that the temperature of the inner cavity of the oven 1 and the outer sides of each group of rollers 5 is uniform. Through the cooperation of each group of connecting plates 29 and connecting plates 1 24, the temperature between and outside each group of rollers 5 can be effectively made uniform, thereby effectively improving the uniformity of vulcanization and avoiding regional temperature differences in the oven 1.

[0051] Working principle: First, the staff opens the two groups of movable doors 30, and then inserts the sealing strip extruded by the extruder into each group of rollers 5 from the left end thereof in turn, and then closes the movable door 30, and turns on the oven 1 to heat the inside thereof. The hot gas will enter the inner cavity of the roller 5 through each group of through holes 9 to heat and vulcanize the sealing strip, and then turns on the motor 14. The motor 14 will drive each group of ventilation pipes 3 to perform circular motion through the rotating plate 2. Through the setting of the teeth 8 on each group of rollers 5, each group of rollers 5 will rotate on the large gear 6 while performing circular motion. While each group of rollers 5 rotates, the fixed ball 26 will reciprocately impact the inner cavity of the semicircular groove 27 under the action of the elastic rod 25, which will continuously vibrate the roller 5 and reduce the adhesion of the sealing strip to the inner cavity of the oven 1. The risk of, while each group of ventilation pipes 3 moves in a circle, the pinion 13 rotates in the ring gear 12, so that the fan blades 11 rotate quickly to absorb the gas in the oven 1 and blow it into the drum 5, so as to realize the circulation of the hot gas in the oven 1. When the rotating plate 2 rotates, it will also drive the reciprocating screw 15 to rotate, so that the piston plate 17 moves back and forth in the inner cavity of the fixed cylinder 16, absorbs the gas in the inner cavity of the oven 1 and discharges it through each group of exhaust holes 23. The rotation of the rotating plate 2 drives each group of connecting plates 1 24 and connecting plates 2 29 to rotate, which will stir the hot gas between and outside each group of drums 5 in the oven 1, so that the temperature between and outside each group of drums 5 is uniform. After the vulcanization is completed, the movable door 30 is opened, and the sealing strips in each group of drums 5 can be taken out using tools.

[0052] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
