Description

Technical Field

[0001] This application relates to the field of rubber product preparation technology, and in particular to a processing equipment and production process for a water-swellable composite rubber strip. Background Technology

[0002] Sealing strips are elastic strip or rod-shaped materials used at joints in building door and window components. They prevent leakage or intrusion of internal and external media, providing functions such as sealing, sound insulation, heat insulation, and vibration damping. To continuously improve the sealing effect of sealing strips, the existing sealing strip industry has evolved from the first stage of producing single-material sealing strips primarily made of PVC, to the second stage of producing single-material sealing strips primarily made of EPDM rubber, effectively addressing the poor weather resistance and sealing performance issues present in the first stage. Finally, the third stage has progressed to producing EPDM foam composite sealing strips, further enhancing the sealing performance of the second stage.

[0003] However, existing sealing strips still have defects in use: Currently, the relevant products on the market include EPDM foam composite sealing strips. During installation, workers need to repeatedly adjust the installation shape and position of the sealing strip according to the requirements. The sealing strip is stretched when pulled and shortened after being placed still, which can easily lead to sealing failure or strip detachment. At the same time, during use, the sealing strip will continuously experience thermal expansion and contraction and aging shrinkage as the service life increases, resulting in sealing failure. Summary of the Invention

[0038] Furthermore, the limiting mechanism includes:

[0039] The limiting body has its top end fixedly connected to the top end of the fixed shell, and its front and rear sides fixedly connected to the inner sidewalls of the fixed shell. Its left and right sides are fixedly connected to the inner sidewalls of the sealing body. The bottom end of the limiting body contacts the transmission belt. A limiting channel is opened in the middle of the limiting body, and the limiting body is movably sleeved with the sealing strip through the limiting channel. The size of the limiting channel is larger than the cross-sectional shape of the sealing strip.

[0040] The limiting channel of the limiting body is provided with six sets of supporting mechanisms, and each set of supporting mechanisms has a certain number of components, which are used to support and fix the outer surface of the sealing strip, so as to further ensure the stability of the movement of the sealing strip.

[0041] Limiting air holes are provided in the inner wall of the limiting body located in the limiting channel. Each supporting mechanism is provided with six limiting air holes, and the six limiting air holes are evenly arranged around the supporting mechanism.

The support membrane is arc-shaped, and the inner wall of the support membrane is fixedly connected to the wall of the first support member and the second support member respectively through a support spring.

[0049] Furthermore, a production process for a water-swellable composite adhesive strip processing equipment includes the following steps:

[0050] The first step is to mix the expanded resin into rubber sheets and the rubber sheets.

[0051] The second step is to feed the glass fiber line at a uniform speed through the feeder, and ensure that the feeder speed is adjusted to match the speed of the first rubber extruder and the second rubber extruder. After the glass fiber line passes through the feeder, it is heated in an electric oven and then put into use. Finally, the glass fiber line is threaded into the mold.

[0052] The third step is to extrude the expanded resin compound sheet through the first rubber extruder, and then extrude the compound rubber sheet through the second rubber extruder. The expanded resin compound sheet and the compound rubber sheet extruded by the first and second rubber extruders, sandwiched with glass fiber lines, are processed through a mold to produce a preliminary unvulcanized sealing strip.

[0053] The fourth step involves the sealing strip being vulcanized in a vulcanizing machine, then cooled in a cooling machine, and finally pulled by a traction machine to complete the production of the sealing strip.

[0054] This application has the following beneficial effects:

[0055] This application provides a processing equipment and production process for a water-swellable composite sealing strip with added fiberglass thread. By incorporating a fiberglass thread inside the middle of the sealing strip, it effectively solves the problem of the sealing strip elongating due to worker pulling during installation and shortening due to shrinkage after resting, leading to sealing failure or detachment. It also solves the problem of sealing failure caused by thermal expansion and contraction and aging shrinkage during use. Simultaneously, the sealing part of the sealing strip uses an expanding resin compound film, effectively enhancing the waterproof performance of the sealing strip. Compared with conventional products, it has higher waterproof performance and better sealing performance, thereby improving the sealing durability of doors and windows, reducing the frequency of door and window replacement, reducing energy waste from indoor air conditioning and heating, and achieving energy conservation and emission reduction. Furthermore, the equipment in this invention is modified from a first rubber extruder, a second rubber extruder, a wire feeder, and an electric heating oven, resulting in low cost, saving processing space, and strong equipment versatility, thus effectively solving the problem of equipment compatibility for wire-added products, composite products, and ordinary single-layer rubber products.

[0056] By setting a transmission block on the outer surface of the transmission belt and placing the sealing strip on top of the transmission block, the contact area between the bottom of the sealing strip and the high-temperature gas is increased, effectively solving the problem of insufficient vulcanization due to the irregular shape of the sealing strip. At the same time, a sealing mechanism and a limiting mechanism are set in the fixed shell, which effectively limit and support the sealing strip located above the transmission block, ensuring the stability of the sealing strip's movement in the vulcanization equipment. In addition, the limiting mechanism is also equipped with limiting air holes, which fully and evenly heat and vulcanize the outer surface of the sealing strip, further solving the problem of insufficient vulcanization in the hidden corners of the sealing strip due to its irregular shape.

[0057] A support mechanism is provided on the inner wall of the limiting channel of the limiting body. This support mechanism consists of a first support member, a second support member, a support ball, and a support membrane. The support ball is movably positioned between the limiting body and the sealing strip, effectively providing support for the sealing strip while reducing friction between the limiting body and the sealing strip. This prevents damage to the outer surface of the sealing strip due to prolonged friction during movement, thus affecting product quality. Simultaneously, the movable arrangement of the support ball by the first and second support members effectively allows the support ball to rotate under the thrust of the moving sealing strip, thus effectively changing the friction mode between the support ball and the outer surface of the sealing strip, further reducing friction on the outer surface of the sealing strip. It can also effectively clean the outer surface of the support ball, preventing impurities from adhering to the outer surface of the sealing strip. The combined effect of these two factors further protects the appearance of the sealing strip during the vulcanization process, thereby improving product quality. In addition, during the process of high-temperature gas being discharged into the limiting channel, the high-temperature gas will push the support membrane to squeeze and shake, thereby effectively shaking impurities away from the gap and preventing impurities from affecting the normal rotation of the support ball. At the same time, the shaking support membrane pushes the high-temperature gas in the opposite direction, effectively disturbing the movement direction of the high-temperature gas, further promoting the full diffusion of the high-temperature gas discharged from the limiting vent, and improving the vulcanization effect on the sealing strip.

[0058] By setting a movable mechanism at the bottom of the workbench, and having the movable mechanism in contact with the transmission block, when the transmission block moves to the position of the movable mechanism with the rotation of the transmission belt, the transmission block effectively squeezes the movable membrane, causing the gas inside the movable membrane to be discharged through the sealing vent. When the transmission block moves out of the position of the movable mechanism, the movable membrane expands under the action of the movable spring, causing external gas to enter the movable membrane through the sealing vent. In this process, not only does the movable membrane effectively rub against the transmission block, cleaning the outer surface of the transmission block and further preventing impurities from contaminating the outer surface of the transmission block from affecting the outer surface of the sealing strip, but the airflow flowing at the sealing vent also effectively blows the sealing strip located outside the vulcanizing equipment horizontally, effectively reducing the possibility of the warm sealing strip being contaminated with dust and impurities, and further improving the production quality of the sealing strip.

[0077] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0078] Example 1

[0079] Please see Figures 1-2 , Figure 10 A water-swellable composite adhesive strip processing equipment, comprising:

[0080] The sealing strip 1 has an irregular cross-section and is composed of an expanded resin compound sheet 101, a compound rubber sheet 102, and a glass fiber thread 103. The compound rubber sheet 102 is the main body of the sealing strip 1 and is made of EPDM rubber, which has the advantages of good aging resistance and high resilience. The expanded resin compound sheet 101 is located on the top of the outer surface of the compound rubber sheet 102 and is made of expanded resin. It is generally placed at the sealing part of the sealing strip 1 that contacts the door frame. The expanded resin expands when it comes into contact with water, effectively increasing the contact area between the sealing strip 1 and the glass and improving the sealing performance. The glass fiber thread 103 is fixedly sleeved inside the compound rubber sheet 102. The glass fiber thread 103 effectively ensures that the sealing strip 1 will not change in size due to stretching and thermal expansion and contraction. It has stable sealing and high sealing performance.

[0081] The first rubber extruder 11 contains an expanded resin compound sheet 101, which is used to extrude and generate the expanded resin compound sheet 101 to provide material for the subsequent lamination of the sealing strip 1.

[0082] The second rubber extruder 12 contains a compounded rubber sheet 102, which is used to extrude and generate the compounded rubber sheet 102 to provide material for the subsequent lamination of the sealing strip 1.

[0083] The fiberglass thread 103 is wound around one end of the wire feeder 13 and has a uniform speed feeding function, which can perform uniform speed feeding operation on the fiberglass thread 103. Since the fiberglass thread is a large coil, the speed of the coil will vary during the wire pulling process, resulting in uneven tension on the thread inside the product and intermittent wrinkles on the product surface. To solve this problem, the wire feeder 13 is equipped with two high-precision speed regulators, which can synchronize with the speed of the first rubber extruder 11 and the second rubber extruder 12. As a result, the fiberglass thread 103 in the middle of the mixed rubber sheet 102 is subjected to uniform tension, thereby ensuring that the product surface is flat and smooth.

[0084] The other end of the fiberglass wire 103 passes through the electric heating oven 14, and the electric heating oven 14 has a heating function, which makes the fiberglass wire 103 more compatible with the rubber compound 102 after baking. It will not slip in the rubber compound 102, and the fiberglass wire 103 will not fall off the rubber compound 102 after being stretched. This makes the length of the sealing strip 1 stable. Therefore, the sealing strip 1 with the added wire will not be affected by thermal expansion and contraction, aging and shrinkage during use, or stretching and deformation during installation, which will cause the sealing strip 1 to fail.

[0085] The mold 15 is connected to the outlet end of the first rubber extruder 11 and the outlet end of the second rubber extruder 12. The other end of the glass fiber line 103 is movably connected to the mold 15. It is used to combine the expanded resin compounded sheet 101, the compounded rubber sheet 102 and the glass fiber line 103 to form the sealing strip 1, thereby realizing the shaping process of the sealing strip 1.

[0086] A vulcanizing device 16 is used to pass through the sealing strip 1. The number of vulcanizing devices 16 is set according to the vulcanization degree requirements of the sealing strip 1. The vulcanizing device 16 is used to perform vulcanization operation on the sealing strip 1, thereby improving the strength, elasticity and other properties of the sealing strip 1.

[0087] The cooling device 17 is used to cool the sealing strip 1 after it passes through the vulcanizing device 16. The sealing strip 1 is movably connected to the cooling device 17 to cool the sealing strip 1, because the temperature of the vulcanized sealing strip 1 is too high to be quickly rolled up.

[0088] The other end of the sealing strip 1 is movably connected to the traction machine 18, which is used to guide the movement of the sealing strip 1 and realize the winding of the sealing strip 1.

[0089] Example 2

[0090] Please see Figures 1-2 , Figure 10 A production process for a water-swellable composite adhesive strip processing equipment includes the following steps:

[0091] The first step is to process the raw materials into expanded resin compound sheet 101 and compound rubber sheet 102 using the formula and production process developed by the company.

[0092] The second step is to feed the glass fiber 103 at a uniform speed through the feeder 13, and ensure that the feeder 13 is adjusted to match the speed of the first rubber extruder 11 and the second rubber extruder 12. The glass fiber 103 after passing through the feeder 13 is then heated in the electric heating oven 14 and ready for use. Finally, the glass fiber 103 is threaded into the mold 15.

[0093] The third step involves extruding the expanded resin compound sheet 101 through the first rubber extruder 11 and the compound rubber sheet 102 through the second rubber extruder 12. The expanded resin compound sheet 101 and the compound rubber sheet 102, which are extruded through the first rubber extruder 11 and the second rubber extruder 12, are sandwiched with glass fiber thread 103 and then processed through the mold 15 to form a preliminarily unvulcanized sealing strip 1.

[0094] The fourth step involves the sealing strip 1 being vulcanized in the vulcanization equipment 16, then cooled in the cooling equipment 17, and finally pulled by the traction machine 18, thus completing the production of the sealing strip 1.

[0095] Example 3

[0096] Based on Example 1, the vulcanizing equipment 16 includes:

[0097] Please see Figures 3-6 , Figures 11-13 Working mechanism 2 is used to move the sealing strip 1 within the vulcanizing equipment 16, providing power for the sealing strip 1 to pass through the vulcanizing equipment 16. Working mechanism 2 includes:

[0098] The workbench 21 has a U-shaped cross-section and is placed on the ground to store the transmission mechanism 3 and the moving mechanism 4, ensuring the stability of the movement of the sealing strip 1.

[0099] Please see Figures 3-5 , Figures 11-12 The transmission mechanism 3 is internally and movably installed on the worktable 21. It is used to place the sealing strip 1 on the transmission mechanism 3, ensuring the sealing strip 1 stably passes through the vulcanizing equipment 16. The transmission mechanism 3 includes:

[0100] The transmission shaft 31 is movably sleeved on the inner walls of both ends of the worktable 21, and the transmission shaft 31 is equipped with a transmission motor to drive the transmission belt 32 to rotate.

[0101] The transmission belt 32 is located inside the worktable 21, and the outer sides of the two transmission shafts 31 are movably connected to the inner ring of the transmission belt 32 to drive the sealing strip 1 to move.

[0102] The outer ring wall of the transmission block 33 and the transmission belt 32 are fixedly connected with several sets of transmission blocks 33, and each set of transmission blocks 33 has two transmission blocks 33. The transmission block 33 is a hemisphere, and a sealing strip 1 is placed on the top of the transmission block 33 to increase the contact area between the bottom of the sealing strip 1 and the high temperature gas, thereby enhancing the uniform vulcanization effect.

[0103] Please see Figures 4-6 , Figure 13 The movable mechanism 4 is fixedly installed at the bottom of the workbench 21 located below the transmission mechanism 3. There are seven movable mechanisms 4. These mechanisms not only clean the transmission mechanism 3 but also effectively provide parallel airflow to the moving sealing strip 1, thereby cooling the sealing strip 1 and preventing environmental impurities from affecting it. The movable mechanism 4 includes:

[0104] The bottom end of the movable plate 41 is fixedly connected to the inner bottom end of the workbench 21, and the top end of the movable plate 41 is in contact with the transmission belt 32. The two sides of the movable plate 41 are fixedly connected to the inner side wall of the workbench 21. There are seven movable plates 41, and the distance between two movable plates 41 is equal to the distance between two sets of transmission block 33 components, which effectively ensures that all the movable mechanisms 4 can change synchronously, thereby enhancing the airflow in the movable mechanism 4.

[0105] The movable membrane 42 has two movable holes at the top of the movable plate 41 corresponding to the transmission block 33, and two movable membranes 42 are provided for each movable hole. The edge of the wall of the movable membrane 42 is fixedly connected to half of the side wall of the movable hole, and the inner wall of the movable membrane 42 is connected to the wall of the movable hole by a movable spring. The shape of the movable membrane 42 when it is not compressed is a quarter circle, and the combined shape of the two movable membranes 42 is adapted to the movable hole. When the transmission block 33 moves to the position of the movable membrane 42, the transmission block 33 squeezes the two movable membranes 42 toward the sides of the movable hole, realizing the outward movement of the airflow in the movable plate 41. When the transmission block 33 moves out of the position of the movable membrane 42, the two movable membranes 42 expand toward the middle of the movable hole, realizing the inward movement of the airflow in the movable membrane 42.

[0106] The first air tube 43 is fixedly sleeved inside the movable plate 41, and one port of the first air tube 43 is fixedly connected to the movable membrane 42, which is used to realize the movement of gas in the movable membrane 42 and the first air tube 43, in preparation for the subsequent gas flow.

[0107] The second air pipe 44 is fixedly sleeved inside the side wall of the workbench 21, and one end of the second air pipe 44 is connected to the other end of the first air pipe 43. It is used to realize the movement of gas in the first air pipe 43 and the second air pipe 44 to prepare for the subsequent gas flow.

[0108] Example 4

[0109] Based on Example 3, the vulcanizing equipment 16 further includes:

[0110] Please see Figures 3-9 , Figures 11-15 The fixing mechanism 5 is located at the upper center of the working mechanism 2. It is used to provide and collect high-temperature gas to achieve full vulcanization of the sealing strip 1. The fixing mechanism 5 includes:

[0111] The fixed shell 51 has an inverted "U" shaped cross-section. The length of the fixed shell 51 is shorter than that of the worktable 21, and the height of the fixed shell 51 is higher than that of the worktable 21. The fixed shell 51 is placed on the ground, and the interior of the fixed shell 51 is movably connected to the worktable 21, that is, the worktable 21 passes through the fixed shell 51. It is used to store the sealing mechanism 6 and the limiting mechanism 7 to achieve full vulcanization of the sealing strip 1.

[0112] Please see Figures 3-5 , Figures 11-13 The sealing mechanism 6 consists of two parts, which are fixedly installed at both ends inside the fixed housing 51. These mechanisms not only provide limiting support for the sealing strip 1 but also reduce the leakage of gas from the fixed mechanism 5, thus improving environmental protection. The sealing mechanism 6 includes:

[0113] The sealing body 61 is fixedly connected to the top of the fixed shell 51 at its top end, and both sides of the sealing body 61 are fixedly connected to the inner sidewalls of the fixed shell 51. The bottom end of the sealing body 61 contacts the transmission belt 32. A sealing channel is provided in the middle of the sealing body 61, and the sealing body 61 is movably sleeved with the sealing strip 1 through the sealing channel. The size of the sealing channel is adapted to the cross-sectional shape of the sealing strip 1. The use of the sealing channel effectively limits and fixes the sealing strip 1, ensuring the stability of the movement of the sealing strip 1 located above the transmission block 33, and effectively reduces the leakage of high-temperature gas, thereby ensuring the full utilization of heat and preventing air pollution.

[0114] A sealing vent 62 is provided inside the sealing body 61, and the other end of the second air pipe 44 passes through the interior of the sealing body 61 and is fixedly connected to the sealing cavity. This is used to allow gas to move within the second air pipe 44 and the sealing body 61, preparing for subsequent gas flow. A sealing vent 62 is provided on the side of the sealing body 61 away from the limiting mechanism 7, and the sealing vent 62 is connected to the sealing cavity. The sealing vent 62 is evenly arranged around the sealing strip 1, which is used to allow gas to move horizontally inside and outside the sealing body 61, thereby providing protection for the outer surface of the sealing strip 1 and reducing the possibility of the high-temperature sealing strip 1 being contaminated with dust and impurities.

[0115] Example 5

[0116] Based on Embodiment 4, the fixing mechanism 5 further includes:

[0117] Please see Figures 3-4 , Figures 7-9 , Figures 14-15 A limiting mechanism 7 is fixedly installed inside the fixed housing 51 between the two sealing mechanisms 6. The limiting mechanism 7 provides limiting support for the sealing strip 1 to ensure sufficient vulcanization of the sealing strip 1. The limiting mechanism 7 includes:

[0118] The limiting body 71 is fixedly connected to the top of the fixed shell 51, and the front and rear sides of the limiting body 71 are fixedly connected to the inner sidewalls of the fixed shell 51. The left and right sides of the limiting body 71 are fixedly connected to the inner sidewalls of the sealing body 61. The bottom end of the limiting body 71 contacts the transmission belt 32. A limiting channel is opened in the middle of the limiting body 71, and the limiting body 71 is movably sleeved with the sealing strip 1 through the limiting channel. The size of the limiting channel is larger than the cross-sectional shape of the sealing strip 1. The use of the limiting channel can effectively limit and fix the sealing strip 1 while reducing the friction of the limiting body 71 on the outer surface of the sealing strip 1, ensuring that the sealing strip 1 is less damaged during the movement.

[0119] The limiting vent 72 is provided on the inner wall of the limiting body 71 located in the limiting channel. Each support mechanism 8 is provided with six limiting vents 72, and the six limiting vents 72 are evenly arranged around the support mechanism 8. The limiting body 71 has a limiting cavity inside, and the limiting cavity is connected to the limiting vent 72. It is used to discharge high temperature gas into the limiting channel and to discharge gas in the limiting channel, thereby achieving full vulcanization of the sealing strip 1.

[0120] Two air inlet pipes 73 are fixedly connected to the top of the limiting body 71 at the outlet end of the vulcanizing equipment 16. The two air inlet pipes 73 are symmetrically arranged. One end of the air inlet pipe 73 is fixedly connected to the limiting cavity, and the other end of the air inlet pipe 73 passes through the fixed shell 51 to discharge high-temperature gas into the limiting cavity of the limiting body 71, in preparation for the high-temperature gas vulcanization of the sealing strip 1.

[0121] Two vent pipes 74 are fixedly connected to the top of the limiting body 71 at the inlet end of the vulcanizing equipment 16, and the two vent pipes 74 are symmetrically arranged. One end of the vent pipe 74 is fixedly connected to the limiting cavity, and the other end of the vent pipe 74 passes through the fixed shell 51. It is used to discharge high-temperature gas into the limiting cavity of the limiting body 71, that is, to effectively discharge the gas containing impurities that has been vulcanized, in preparation for the continuous use of the vulcanizing equipment 16.

[0122] Please see Figures 7-9 , Figures 14-15 The limiting channel of the limiting body 71 is provided with six sets of supporting mechanisms 8, and each set of supporting mechanisms 8 has a certain number of components. These mechanisms are used to support and fix the outer surface of the sealing strip 1, further ensuring the stability of the movement of the sealing strip 1. The supporting mechanism 8 includes:

[0123] The first support member 81 has a limiting hole on the inner wall of the limiting body 71 inside the limiting channel, and the limiting hole is connected to the limiting cavity. The first support member 81 is fixedly connected to the wall of the limiting hole near the direction of the sealing strip 1. The first support member 81 is arc-shaped and does not contact the supporting ball 83. The shape of the first support member 81 is designed to prevent impurities on the supporting ball 83 from being cleaned by friction when it does not enter the middle of the movable hole, and at the same time effectively ensures that impurities located in the support mechanism 8 will not move outward again.

[0124] The second support member 82 is fixedly connected to the wall of the limiting hole near the sealing strip 1. The second support member 82 is arc-shaped and contacts the support ball 83. There is an oblique gap between the first support member 81 and the second support member 82. The gap is closer to the support membrane 84 and closer to the second support member 82. This helps to clean impurities on the surface of the support ball 83 into the gap and discharge them into the support membrane 84 through the gap.

[0125] The support ball 83 is a sphere, and two-thirds of the support ball 83 is located inside the limiting hole. The combination of the first support member 81 and the second support member 82 is movably engaged with the support ball 83, and the support ball 83 is in contact with the outer surface of the sealing strip 1. The support ball 83 can provide support for the movement of the sealing strip 1. At the same time, during the movement of the sealing strip 1, the support ball 83 is affected by the sealing strip 1 and rotates, causing sliding friction between the support ball 83 and the sealing strip 1, effectively reducing frictional damage to the sealing strip 1.

[0126] A support membrane 84 is provided inside the limiting hole, and the edge of the support membrane 84 is fixedly connected to the edge wall of the first support member 81 and the second support member 82. The support membrane 84 is arc-shaped, and the inner wall of the support membrane 84 is fixedly connected to the wall of the first support member 81 and the second support member 82 respectively through a support spring. When the gas moves, it can effectively vibrate the support membrane 84, so that impurities are moved away from the gap between the first support member 81 and the second support member 82, thereby ensuring that impurities will not move outward again. At the same time, the vibration of the support membrane 84 disrupts the gas movement in the opposite direction, so that the gas flow can move in multiple directions when it is discharged from the limiting air hole 72, further improving the vulcanization effect of the high temperature gas on the sealing strip 1.

[0127] The working principle of the method of using this invention is as follows:

[0128] When preparing the sealing strip 1, the raw materials are first made into an expanded resin compound sheet 101 and a compound rubber sheet 102. Then, the glass fiber thread 103 is fed out at a uniform speed through the feeder 13, while ensuring that the linear speed of the feeder 13 is matched with the speed of the first rubber extruder 11 and the second rubber extruder 12. This ensures that the glass fiber thread 103 in the middle of the compound rubber sheet 102 is evenly stressed during production, thus ensuring a smooth and flat product surface. The glass fiber thread 103 after passing through the feeder 13 is then heated in an electric heating oven 14 before use, effectively ensuring higher compatibility between the glass fiber thread 103 and the compound rubber sheet 102. Finally, the glass fiber thread 103 is threaded into the mold 15. At the same time, the expanded resin compound sheet 101 is extruded through the first rubber extruder 11, and the compound rubber sheet 102 is extruded through the second rubber extruder 12. The expanded resin compound sheet 101 and the compound rubber sheet 102 extruded through the first rubber extruder 11 and the second rubber extruder 12 are then processed. 2. The glass fiber thread 103 is passed through the mold 15, where the expanded resin compound sheet 101, the compound rubber sheet 102, and the glass fiber thread 103 are processed into a preliminary uncured sealing strip 1. Because a glass fiber thread 103 is set in the middle of the sealing strip 1, the problem of the sealing strip 1 stretching due to worker pulling during installation and shrinking after resting, resulting in sealing failure or falling off, is effectively solved. It also solves the problem of sealing failure due to thermal expansion and contraction and aging shrinkage during use. At the same time, the sealing part of the sealing strip 1 uses the expanded resin compound sheet 101, which effectively enhances the waterproof performance of the sealing strip 1. Compared with conventional products, it has higher waterproof performance and better sealing performance. Then, the sealing strip 1 is first vulcanized by the vulcanization equipment 16, and the vulcanized sealing strip 1 is then cooled by the cooling equipment 17. Finally, it is pulled by the traction machine 18, thus completing the production of the sealing strip 1.

[0129] During the vulcanization process of the sealing strip 1, the sealing strip 1 is first placed on the top of the transmission block 33, so that when the transmission belt 32 moves the sealing strip 1, the bottom end of the sealing strip 1 is in full contact with the high-temperature gas in the limiting mechanism 7, ensuring the sufficient vulcanization of the bottom of the sealing strip 1. At the same time, the support mechanism 8 located in the limiting channel effectively supports the outer surface of the sealing strip 1, which not only effectively ensures the stability of the sealing strip 1 when it moves, but also provides space for the high-temperature gas to be evenly distributed on the outside of the sealing strip 1, effectively improving the vulcanization effect of the irregular sealing strip 1.

[0130] When the sealing strip 1 moves within the limiting mechanism 7, the support ball 83, which slides and rubs against the sealing strip 1, can rotate synchronously with the sealing strip 1. This not only further reduces the friction between the support ball 83 and the sealing strip 1 and improves the protection of the sealing strip 1, but also effectively cleans dust and impurities that may be attached to the surface of the support mechanism 8 through the first support member 81 and the second support member 82 into the support membrane 84, ensuring the cleanliness of the surface of the support ball 83 that contacts the sealing strip 1.

[0131] During the process of high-temperature gas being discharged from the limiting cavity of the limiting body 71 to the limiting channel through the limiting vent 72, the pushing force of the high-temperature gas and the elastic force of the limiting spring reciprocate to effectively shake the support membrane 84. This causes impurities located in the gap between the first support member 81 and the second support member 82 to be shaken away from the gap, preventing impurities from affecting the normal rotation of the support ball 83. At the same time, the shaking support membrane 84 pushes the high-temperature gas in the opposite direction, effectively disturbing the movement direction of the high-temperature gas, further promoting the full diffusion of the high-temperature gas discharged from the limiting vent 72, and improving the vulcanization effect on the sealing strip 1.

[0132] When the transmission belt 32 drives the transmission block 33 to the position of the movable mechanism 4, the transmission block 33 pushes the two movable membranes 42 to compress, so that the gas in the movable membranes 42 is discharged horizontally after passing through the first air pipe 43, the second air pipe 44, the sealing cavity, and the sealing air hole 62. When the transmission belt 32 drives the transmission block 33 to move out of the position of the movable mechanism 4, the two movable membranes 42 return to their original state, so that the gas moves horizontally into the sealing air hole 62. Thus, the movable membranes 42 not only effectively rub against the transmission block 33 to clean the outer surface of the transmission block 33 and prevent impurities from affecting the outer surface of the sealing strip 1, but also the horizontally moving gas flow at the sealing air hole 62 effectively blows the sealing strip 1 located outside the vulcanizing equipment 16 horizontally, thereby providing airflow protection for the sealing strip 1, effectively reducing the possibility of the temperature-sensitive sealing strip 1 being contaminated with dust and impurities, and further improving the production quality of the sealing strip 1.
