[0037] The present application is further described in detail below in conjunction with the accompanying drawings.

[0038] The embodiment of the present application discloses a waterproofing membrane production line.

[0039] Reference Figure 1 and Figure 2 The waterproofing coil production line includes a screw extruder 11, an automatic screen changer 12, a distributor 13, an extrusion die 14, a roller forming device 15, a trimming device 16, a first tension roller 17, a first traction machine 18, a first deviation correcting device 19, a first gluing device 20, a side film placing device 21, a first face film placing device 22, a first roller pressing device 23, a winding device 24 and a control system 25. The control system 25 is electrically connected to each electrical device and can control the on and off of each electrical device.

[0040] There are two screw extruders 11 , and a feeding end is provided on the screw extruder 11 , and a worker can add materials into the screw extruder 11 through the feeding end.

[0041] The automatic screen changer 12 is located at the output end of the screw extruder 11 and is used to filter out impurities in the molten mixture.

[0042] Reference Figure 1 and Figure 2 The distributor 13 is located at the output end of the automatic screen changer 12, and the extrusion die 14 is located at the output end of the distributor 13. The number of the extrusion die 14 is one, and the extrusion die 14 has two feed ends. The two feed ends of the extrusion die 14 are respectively connected to the two distributors 13. The two distributors 13 control the flow rate of the molten material entering the extrusion die 14.

[0043] The screw extruder 11, the automatic screen changer 12, the distributor 13 and the extrusion die 14 constitute a carcass production device, and the carcass production device is used to produce a carcass.

[0044] The roll forming device 15 is located at the rear side of the discharge end of the extrusion die 14. When in use, the tire body extruded by the extrusion die 14 enters the roll forming device 15, and the roll forming device 15 rolls the tire body. The roll forming device 15 uses a roller calender, such as a double-roll calender, a three-roll calender and other industrial equipment. In addition, at least one cooling roller 151 for cooling the tire body is also installed on the roll forming device 15. Preferably, in this embodiment, the number of cooling rollers 151 is two. When in use, the tire body passes through the two cooling rollers 151 in sequence for cooling.

[0045] Reference Figure 1 and Figure 2The trimming device 16 is located at the rear end of the cooling roller 151. After the tire body is cooled by the cooling roller 151, the trimming device 16 trims the edges of both sides of the tire body. Specifically, the cutting knife of the trimming device 16 can be a circular knife. There are two circular knives, and the two circular knives trim the edges of both sides of the tire body respectively.

[0046] The first tension roller 17 is located at the rear end of the trimming device 16. The first tension roller 17 detects the tension of the tire body in real time and transmits the detected tension data of the tire body to the control system 25, so that the staff can obtain the tension of the tire body in time and adjust the tension of the tire body in time.

[0047] Specifically, the base on which the first tension roller 17 is installed can be a pressure sensor. If the side end of the pressure sensor is fixedly mounted on the support frame and the carcass is wrapped around the first tension roller 17, the data measured by the pressure sensor is the tension of the carcass. If the bottom of the pressure sensor is fixedly mounted on the support frame and the carcass is wrapped around the first tension roller 17, the data measured by the pressure sensor minus the gravity of the first tension roller 17 and its accessory components is the tension of the carcass.

[0048] Reference Figure 1 and Figure 2 The first traction machine 18 is located at the rear end of the first tension roller 17, and the first traction machine 18 tractions the carcass. When it is detected that the tension of the carcass at the first tension roller 17 is too large, the first traction machine 18 reduces the tension of the carcass by reducing the output speed; when it is detected that the tension of the carcass at the first tension roller 17 is too small, the first traction machine 18 increases the tension of the carcass by increasing the output speed.

[0049] The first deviation-correcting device 19 is located at the rear end of the first traction machine 18 . The first deviation-correcting device 19 corrects the carcass pulled out by the first traction machine 18 to reduce the deviation during the production and transmission of the carcass.

[0050] The first glue coating device 20 is located at the rear end of the first deviation correcting device 19, and the glue outlet of the first glue coating device 20 is located above the tire body. The first glue coating device 20 applies glue to the upper surface of the tire body.

[0051] The edge film placing device 21 is located at the rear end of the first glue coating device 20. After the first glue coating device 20 has finished gluing the carcass, the edge film placing device 21 covers the edge of one side or both sides of the carcass with edge film.

[0052] Reference Figure 1 and Figure 2 The first mask placing device 22 is located at the rear end of the edge film placing device 21, and the first mask placing device 22 places the first mask on the upper surface of the tire body.

[0053] The first rolling device 23 is located at the rear end of the first mask placing device 22. When the edge film and the first mask are placed on the upper end of the glue coated on the upper surface of the tire body, the first rolling device 23 rolls the upper ends of the edge film and the first mask to complete the bonding between the edge film and the upper surface of the tire body and the first mask and the upper surface of the tire body.

[0054] Reference Figure 1 and Figure 2 The winding device 24 is located at the end of the entire production line. After the first rolling device 23 completes the rolling of the waterproof coiled material, the winding device 24 rolls up the waterproof coiled material.

[0055] When in use, the extrusion die 14 extrude the tire body, and then the tire body is roll-formed by the roller forming device 15, and then the tire body is cooled by two cooling rollers 151, and then the two edges of the tire body are trimmed by the trimming device 16. In the process of producing the tire body, the first tension roller 17 always detects the tension of the tire body in real time and feeds it back to the control system 25, so that the staff can timely know the tension of the tire body between the trimming device 16 and the first traction machine 18, and the staff can adjust the tension of the tire body. Specifically, the tension of the tire body can be adjusted by adjusting the speed of the output shaft of the first traction machine 18. After the tire body passes through the first traction machine 18, it is corrected by the first deviation correcting device 19, and then the first glue coating device 20 coats glue on the upper surface of the tire body, and after coating, the upper surface of the tire body is covered with an edge film and a first face film, and then rolled by the first rolling device 23, and finally the waterproof coiled material after rolling is rolled by the winding device 24.

[0056] Further, refer to Figure 1 and Figure 2 The waterproof membrane production line also includes a sand spreading device 31, a second tractor 32, a second mask placing device 33, a second rolling device 34, a sand sweeping and returning device 35, a coating device 36 and a drying device 37.

[0057] The sand spreading device 31 is located at the rear end of the first rolling device 23. When producing some waterproof coiled materials that require sand particles, the sand spreading device 31 is used to spread sand on the upper surface of the carcass.

[0058] The second traction machine 32 is located at the rear end of the sand spreading device 31, and the second traction machine 32 is used to continue to pull the carcass forward.

[0059] Reference Figure 1 and Figure 2 The second mask placing device 33 is located at the rear end of the second tractor 32, and the second mask placing device 33 is used to place the second mask on the upper surface of the tire body.

[0060] In other embodiments, the second mask can also be an isolation film. When the second mask is an isolation film, after the first mask is applied to the upper surface of the carcass, the second mask is applied on the upper surface of the first mask to reduce adhesion between the waterproof roll materials when they are rolled up.

[0061] The second rolling device 34 is located at the rear end of the second mask placing device 33 , and the second rolling device 34 rolls the second mask placed by the second mask placing device 33 and the tire body.

[0062] The sand sweeping and returning device 35 is located between the second traction machine 32 and the second mask placing device 33. After the carcass passes through the second traction machine 32, the sand sweeping and returning device 35 sweeps and returns the sand on the carcass, so that the sand is more evenly distributed on the upper surface of the carcass.

[0063] The coating device 36 is located between the sand sweeping and returning device 35 and the second film placing device 33. When producing some waterproof coiled materials that need to be coated, the coating device 36 is used to apply coating to the upper surface of the carcass.

[0064] Reference Figure 3 and Figure 4 The coating device 36 includes a frame 361 and a coating assembly arranged on the frame 361, and the coating assembly includes a supporting roller 362 and a coating roller 363. Both ends of the supporting roller 362 and both ends of the coating roller 363 are rotatably connected to the frame 361, and the waterproof coiled material is transported between the supporting roller 362 and the coating roller 363. The interior of the coating roller 363 is a hollow structure, and a plurality of discharge holes 3631 are evenly opened on the cylinder wall of the coating roller 363, and the distance between two adjacent discharge holes 3631 is 2 cm.

[0065] A paint box, a feed pump, a feed pipe and a discharge pipe are placed at the bottom of the frame 361. The feed pump is placed in the paint inside the paint box. The two ends of the feed pipe are respectively connected to the output end of the feed pump and one end of the paint roller. One end of the discharge pipe is connected to the other end of the paint roller, and the other end of the discharge pipe extends into the paint inside the paint box. An overflow valve is also connected to the discharge pipe to control and adjust the pressure of the paint in the discharge pipe so that the inside of the paint roller is in an environment with a certain pressure, that is, when the internal pressure of the paint roller is less than the set pressure of the overflow valve, the overflow valve is closed, and the paint can be squeezed into the discharge hole for discharge. When the internal pressure of the paint roller is greater than the set pressure value of the overflow valve, the paint can be discharged from the discharge pipe and transported back to the paint box again to complete the circulation of the paint. The outer wall of the paint roller is also wrapped with a permeable layer, and the paint can penetrate from the permeable layer, so that it can be more evenly applied to the upper surface of the tire body.

[0066] Among them, the permeable layer can be made of non-woven fabrics or other fabrics that can achieve permeability. Non-woven fabrics have good permeability and are convenient for uniform seepage of the coating, so that the coating can be more evenly coated on the upper surface of the waterproof membrane.

[0067] During the conveying process of the carcass, the feed pump absorbs the paint in the paint box and conveys it to the internal cavity of the paint roller through the feed pipe. After the paint roller is filled with paint, the paint is squeezed out from the discharge hole of the paint roller, then penetrates through the permeation layer and is smeared on the upper surface of the waterproof membrane. The paint will not float into the air to cause pollution, and the paint in the paint roller can also be discharged from the discharge pipe to complete the circulation of the paint. The equipment is simple and convenient, highly reliable and not easy to damage.

[0068] Reference Figure 1 and Figure 2 The drying device 37 is located between the coating device 36 and the second film placing device 33. After the coating is applied to the upper surface of the carcass, the coating on the carcass is dried by the drying device 37 to facilitate the subsequent production of the waterproof coiled material.

[0069] When in use, the tire body is extruded by the extrusion die 14, and then the tire body is roll-formed by the roll-forming device 15, and then the tire body is cooled by two cooling rollers 151, and then the two edges of the tire body are trimmed by the trimming device 16. In the process of producing the tire body, the first tension roller 17 always detects the tension of the tire body in real time and feeds it back to the control system 25, so that the staff can timely know the tension of the tire body between the trimming device 16 and the first traction machine 18, and it is convenient for the staff to adjust the tension of the tire body. Specifically, the tension of the tire body can be adjusted by adjusting the speed of the output shaft of the first traction machine 18. After the tire body passes through the first traction machine 18, it passes through the first The deviation correction device 19 performs deviation correction, and then the first glue coating device 20 applies glue to the upper surface of the tire body. When passing through the sand spreading device 31, the sand spreading device 31 spreads sand on the upper surface of the tire body, and after being pulled by the second traction machine 32, the sand sweeping and returning device 35 sweeps and returns the sand on the upper surface of the tire body to make the sand particles as evenly distributed on the tire body as possible. Then the rapid coating device 36 covers a layer of coating on the upper end of the sand particles, and then the drying device 37 dries the coating. The second mask placing device 33 places a second mask on the upper surface of the coating, and then the second rolling device 34 rolls the waterproof membrane, and finally the winding device 24 winds up the waterproof membrane.

[0070] Further, refer to Figure 1 and Figure 2The waterproof membrane production line also includes a second tension roller 41 and a third traction machine 42. The second tension roller 41 is located between the drying device 37 and the second mask placing device 33, and the third traction machine 42 is located between the second rolling device 34 and the winding device 24. When in use, the second tension roller 41 can also detect the tension of the tire body in real time, and transmit the tension data detected on the tire body to the control system 25, so that the staff can promptly know the tension of the tire body between the drying device 37 and the second mask placing device 33, and then the staff can adjust the tension of the tire body by adjusting the rotation speed of the third traction machine 42.

[0071] Specifically, the base on which the second tension roller 41 is installed can be a pressure sensor. If the side end of the pressure sensor is fixedly mounted on the support frame and the carcass is wrapped around the second tension roller 41, the data measured by the pressure sensor is the tension of the carcass. If the bottom of the pressure sensor is fixedly mounted on the support frame and the carcass is wrapped around the second tension roller 41, the data measured by the pressure sensor minus the gravity of the second tension roller 41 and its accessory components is the tension of the carcass.

[0072] Reference Figure 1 and Figure 2 When it is detected that the tension of the carcass at the second tension roller 41 is too large, the third traction machine 42 reduces the tension of the carcass by reducing the output speed; when it is detected that the tension of the carcass at the second tension roller 41 is too small, the third traction machine 42 increases the tension of the carcass by increasing the output speed.

[0073] Further, refer to Figure 1 and Figure 2 The waterproofing coiled material production line also includes a bottom film unwinding device 51 and a second gluing device 52.

[0074] The bottom film unwinding device 51 is located at the front end of the second rolling device 34. Specifically, the bottom film can be unwound on the bottom film unwinding device 51. The bottom film can be an isolation film or a non-woven fabric or other fabric. Two groups of bottom film unwinding devices 51 can be provided. When in use, the two groups of bottom film unwinding devices 51 are used alternately to reduce downtime and improve production efficiency.

[0075] The second glue coating device 52 is located between the base film unwinding device 51 and the second rolling device 34. The second glue coating device 52 coats glue on the upper surface of the base film, and then the second rolling device 34 rolls the base film and the bottom of the carcass.

[0076] Reference Figure 5The second gluing device 52 includes a gluing mold 521 and a cooling roller 522. The gluing mold 521 is located at the front end of the cooling roller 522. When in use, the base film unwinding device 51 unwinds the base film. When the base film passes through the gluing mold 521, the gluing mold 521 applies glue to the upper surface of the base film. Then, when the base film passes through the cooling roller 522, the cooling roller 522 cools the glue on the base film to prevent the glue from flowing on the base film, and allows the glue to cool and shape on the base film. Then, the base film and the carcass are adhered together under the rolling pressure of the second rolling device 34.

[0077] When the base film is an isolation film, a single silicone oil release film can be used as the isolation film. At this time, the glue is not easy to adhere to the base film. When the side of the base film coated with glue is pressed against the tire body, the glue is transferred to the tire body and adheres to the tire body, so that the bottom surface of the tire body is coated with glue.

[0078] Reference Figure 1 and Figure 2 When producing waterproof coiled materials that require coating on both sides of the carcass, the bottom film unwinding device 51 can unwind some bottom films, and then use the carcass, the side film unwinding device and the first surface film unwinding device 22 to produce a product. The bottom film unwinding device 51 can also use the carcass, the sand spreading device 31 and the second surface film unwinding device 33 to produce another product. The bottom film unwinding device 51 can also use the carcass and the second surface film unwinding device 33 to produce another product. When the bottom film unwinding device 51 unwinds non-woven fabric, the bottom film unwinding device 51 can also directly produce a product with the second surface film unwinding device 33. Therefore, this embodiment uses the production line to produce various types of waterproof coiled materials, realizing multiple uses of one line, which not only improves the production efficiency of various products of waterproof coiled materials, but also reduces the layout of various product production lines, reduces the production cost of various products of waterproof coiled materials, and reduces the cost of the enterprise, achieving the purpose of reducing costs and increasing efficiency.

[0079] Further, refer to Figure 1 and Figure 2 The waterproofing membrane production line also includes a storage rack 53 and a second correcting device 54. The storage rack 53 is located between the third traction machine 42 and the winding device 24. During the process of the control system 25 controlling the tire body tension, the rotation speed of the third traction machine 42 may increase, but the winding device 24 may not be able to rewind these waterproofing membranes in time, so these waterproofing membranes are stored in the storage rack 53.

[0080] Reference Figure 1 and Figure 2The second deflection-correcting device 54 is located between the material storage rack 53 and the winding device 24. Due to the existence of the material storage rack 53, when there are more waterproof coiled materials in the material storage rack 53, the tension of the waterproof coiled materials in the material storage rack 53 will be weakened or disappear, and the waterproof coiled materials are prone to deviation during the process of the winding device 24 winding the waterproof coiled materials. Therefore, the second deflection-correcting device 54 is provided to correct the deflection of the waterproof coiled materials before the winding device 24 winds them up, so as to facilitate the winding device 24 to wind up the waterproof coiled materials.

[0081] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
