The existing dip coating mechanism lacks a limiting mechanism, which may cause the roll to deviate during operation, affecting the dip coating effect; at the same time, unsuitable tension may lead to uneven dip coating thickness or roll deformation, affecting product quality.
A limiting component and an adjusting component were designed. The limiting component fixes the roll material roller with a limiting ring and a fixing rod, while the adjusting component adjusts the tension by adjusting the height of the pressure roller, so as to ensure that the roll material roller is stable in position and has appropriate tension during operation.
This effectively avoids positional shifts and tension issues on the roll material during operation, ensuring the stability of the dip coating effect and improving product quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof membrane production technology, and in particular to an impregnation and coating mechanism for SBS waterproof membrane production. Background Technology
[0002] SBS waterproof membrane is a sheet-like roll material made of SBS thermoplastic elastomer modified bitumen as the coating material, combined with polyester felt and other base materials and polyethylene film and other isolation materials. It has the characteristics of weather resistance, chemical corrosion resistance, excellent waterproof performance, high tensile strength and large elongation, self-healing ability, and convenient construction. It can be divided into different types according to the base material, physical and mechanical properties and upper surface isolation materials. It is suitable for waterproofing and moisture-proofing in various scenarios such as building roofs, underground projects, water tanks, bridges and tunnels. During construction, the base surface must be properly treated, and the hot-melt, self-adhesive, wet-laying methods should be selected according to the situation. Pay attention to the laying direction, sequence and overlap specifications.
[0003] In the production of waterproof membranes, dip coating is required. However, current dip coating mechanisms are relatively simple in structure and lack a mechanism to limit the position of the membrane rollers. During operation, the membrane rollers may shift due to vibration, which affects the dip coating effect. Furthermore, they cannot adjust the membrane tension. Excessive tension will result in a thin coating thickness, while insufficient tension will cause deformation of the membrane, seriously affecting the quality of the waterproof membrane. Therefore, this application proposes a dip coating mechanism for the production of SBS waterproof membranes to meet the requirements. Utility Model Content
[0004] In order to overcome the shortcomings of existing devices, such as the effect of roll material misalignment on the coating effect and the effect of excessive or insufficient tension on product quality, this utility model provides a coating mechanism for SBS waterproof roll material production.
[0005] The technical implementation scheme of this utility model is as follows: an impregnation and coating mechanism for SBS waterproof membrane production, including an impregnation and coating box and two sets of membrane rollers. A first mounting frame is fixedly connected to both ends of one side of the impregnation and coating box. A rotating shaft is rotatably connected to one side of the first mounting frame. A limit component is provided on the outer periphery of the rotating shaft. A motor with a drive shaft fixedly connected to the rotating shaft is installed on the other side of the first mounting frame. A second mounting frame is fixedly connected to both sides of the middle part of the impregnation and coating box. An mounting plate is provided between the two sets of second mounting frames. A connecting plate is fixedly connected to both sides of the bottom of the mounting plate. A pressure roller is rotatably connected between the two sets of connecting plates. An adjustment component is provided at the connection between the mounting plate and the second mounting frame.
[0006] Optionally, the limiting component includes a guide groove, a limiting ring, a guide block, a fixing hole, a through groove, and a fixing rod. The guide groove is opened at the top of the rotating shaft. The limiting ring is sleeved and slidably connected to the outer periphery of the rotating shaft. The guide block is fixedly connected to the inner wall of the top of the limiting ring and slidably connected to the guide groove. Several sets of fixing holes are provided and are opened at the inner wall of the bottom of the guide groove. The through groove passes through the limiting ring and the guide block. The fixing rod is movably connected to the through groove and is adapted to the size of the fixing hole.
[0007] Optionally, the limiting component further includes a first slide groove, a first slider, a first spring, and a pull block. The first slide groove is formed in the inner wall of the through groove. The first slider is fixedly connected to the outer periphery of the fixed rod and slidably connected to the first slide groove. The first spring is sleeved on the outer periphery of the fixed rod and its two ends are respectively fixedly connected to the top of the first slider and the inner wall of the top of the first slide groove. The pull block is fixedly connected to the top of the pull rod.
[0008] Optionally, the roll material is sleeved and slidably connected to the rotating shaft, and a drive block that is slidably connected to the guide groove is fixedly connected to the inner wall of the top of the roll material.
[0009] Optionally, the adjustment assembly includes an adjustment groove, an adjustment block, a socket, a connecting groove, and a rod. The adjustment groove is formed on the inner surface of the second mounting bracket. The adjustment block is fixedly connected to both sides of the mounting plate and slidably connected to the adjustment groove. Several sets of sockets are provided and formed on the inner wall of the adjustment groove. The connecting groove is formed on the inner wall of the mounting plate and passes through the adjustment block. The rod is movably connected to the connecting groove and is adapted to the size of the socket.
[0010] Optionally, the adjustment assembly further includes a second slide groove, a second slider, and a second spring. The second slide groove is formed on the top of the mounting plate and communicates with the connecting groove. The second slider is fixedly connected to the end of the plug rod away from the second mounting bracket and slidably connected to the second slide groove. The second spring is installed inside the second slide groove and its two ends are respectively fixedly connected to the inner wall of the second slider away from the second mounting bracket and the inner wall of the slide groove away from the second mounting bracket.
[0011] This utility model has the following advantages:
[0012] 1. This utility model, by setting a limiting component, pulls the outer limiting ring upwards, causing the fixing rod to slide upwards along the first slide groove and compress the first spring. When the fixing rod moves out of the fixing hole, the guide block slides outwards along the guide groove until the limiting ring separates from the rotating shaft. Then, the roll material is sleeved on the outer circumference of the rotating shaft and the drive block is placed in the guide groove until one end is tightly fitted with the inner limiting ring. At this time, the removed limiting ring is sleeved on the outer circumference of the rotating shaft in the same way and tightly fitted with the other end of the roll material. Then, the pull block is released, the first spring rebounds and drives the fixing rod downwards through the first slider. When the fixing rod is inserted into the fixing hole at the current position, the limiting ring can be fixed at the current position. At this time, the roll material can be limited. This design allows the device to limit roll material of different sizes during operation, thereby avoiding deviation during operation and affecting the dipping effect.
[0013] 2. This utility model features an adjustment component. The second slider slides along the second groove towards the center of the mounting plate, compressing the second spring. During this process, the insertion rod moves synchronously towards the center of the mounting plate along with the second slider. When the insertion rod moves out of the insertion hole, the adjustment block slides along the adjustment groove, causing the pressure roller to rise and fall via the mounting plate. When the pressure roller reaches the appropriate height, the second slider is released, the second spring rebounds, and the insertion rod moves to both sides via the second slider. When the insertion rod is inserted into the insertion hole at the current height, the pressure roller is fixed at the current height, thus completing the adjustment of the roll tension. This design allows the device to adjust the roll tension by adjusting the height of the pressure roller, preventing excessive or insufficient tension from affecting product quality.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in this document are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0021] An impregnation mechanism for SBS waterproof membrane production includes an impregnation tank 1 and two sets of membrane rollers 2. A first mounting frame 3 is fixedly connected to both ends of one side of the impregnation tank 1. A rotating shaft 4 is rotatably connected to one side of the first mounting frame 3. A limit component 5 is provided on the outer periphery of the rotating shaft 4. A motor 6 with a drive shaft fixedly connected to the rotating shaft 4 is installed on the other side of the first mounting frame 3. A second mounting frame 7 is fixedly connected to both sides of the middle of the impregnation tank 1. An mounting plate 8 is provided between the two sets of second mounting frames 7. A connecting plate 9 is fixedly connected to both sides of the bottom of the mounting plate 8. A pressure roller 10 is rotatably connected between the two sets of connecting plates 9. An adjustment component 11 is provided at the connection between the mounting plate 8 and the second mounting frame 7.
[0022] It should be noted that the limiting component 5 enables the device to limit the rolls 2 of different sizes during operation, thereby preventing them from shifting and affecting the dipping effect. The adjusting component 11 enables the device to adjust the tension of the roll by adjusting the height of the pressure roller 10, thereby preventing the tension from being too high or too low and affecting the dipping effect.
[0023] like Figure 2 and Figure 3 As shown, the limiting component 5 includes a guide groove 51, a limiting ring 52, a guide block 53, a fixing hole 54, a through groove 55, and a fixing rod 56. The guide groove 51 is opened at the top of the rotating shaft 4. The limiting ring 52 is sleeved and slidably connected to the outer periphery of the rotating shaft 4. The guide block 53 is fixedly connected to the inner wall of the top of the limiting ring 52 and slidably connected to the guide groove 51. Several sets of fixing holes 54 are provided and are opened at the bottom inner wall of the guide groove 51. The through groove 55 passes through the limiting ring 52 and the guide block 53. The fixing rod 56 is movably connected to the through groove 55 and is adapted to the size of the fixing hole 54.
[0024] It should be noted that by removing the fixing rod 56 from the fixing hole 54, the guide block 53 can be slid along the guide groove 51, thereby adjusting the position of the two sets of limiting rings 52 so that they can limit the rolls 2 of different sizes.
[0025] like Figure 3 As shown, the limiting component 5 also includes a first slide groove 57, a first slider 58, a first spring 59, and a pull block 510. The first slide groove 57 is formed in the inner wall of the through groove 55. The first slider 58 is fixedly connected to the outer periphery of the fixed rod 56 and slidably connected to the first slide groove 57. The first spring 59 is sleeved on the outer periphery of the fixed rod 56 and its two ends are respectively fixedly connected to the top of the first slider 58 and the top inner wall of the first slide groove 57. The pull block 510 is fixedly connected to the top of the pull rod.
[0026] It should be noted that pulling the pull block 510 upward will cause the first slider 58 to slide upward along the first slide groove 57 via the fixed rod 56 and compress the first spring 59. Releasing the pull block 510 will cause the first spring 59 to rebound and cause the fixed rod 56 to move downward via the first slider 58.
[0027] like Figure 1 As shown, the roll material roller 2 is sleeved and slidably connected to the rotating shaft 4, and a drive block that is slidably connected to the guide groove 51 is fixedly connected to the inner wall of the top of the roll material roller 2.
[0028] It should be noted that the installation of the roll material roller 2 can be completed by placing the drive block at an angle aligned with the guide groove 51 and then fitting the roll material roller 2 onto the outer circumference of the rotating shaft 4. During operation, the rotating shaft 4 can drive the roll material roller 2 to rotate synchronously through the guide groove 51 and the drive block, thereby performing the roll material winding and unwinding operations.
[0029] like Figure 4 and Figure 5 As shown, the adjustment assembly 11 includes an adjustment groove 111, an adjustment block 112, a socket 113, a connecting groove 114, and a plug rod 115. The adjustment groove 111 is opened on the inner surface of the second mounting bracket 7. The adjustment block 112 is fixedly connected to both sides of the mounting plate 8 and slidably connected to the adjustment groove 111. Several sets of sockets 113 are provided and are opened on the inner wall of the adjustment groove 111. The connecting groove 114 is opened on the inner wall of the mounting plate 8 and passes through the adjustment block 112. The plug rod 115 is movably connected to the connecting groove 114 and is adapted to the size of the socket 113.
[0030] It should be noted that by removing the insert rod 115 from the socket 113, the adjusting block 112 can be slid along the adjusting groove 111 to adjust the height of the mounting plate 8. Inserting the insert rod 115 into the socket 113 will fix the mounting plate 8 at the current height.
[0031] like Figure 5As shown, the adjustment assembly 11 also includes a second slide groove 116, a second slider 117, and a second spring 118. The second slide groove 116 is opened on the top of the mounting plate 8 and communicates with the connecting groove 114. The second slider 117 is fixedly connected to the end of the plug rod 115 away from the second mounting bracket 7 and slidably connected to the second slide groove 116. The second spring 118 is installed inside the second slide groove 116 and its two ends are respectively fixedly connected to the inner wall of the second slider 117 away from the second mounting bracket 7 and the inner wall of the slide groove 116 away from the second mounting bracket 7.
[0032] It should be noted that the second spring 118 can be squeezed by sliding the second slider 117 along the second slide groove 116 toward the center of the mounting plate 8. During this process, the insertion rod 115 will move toward the center of the mounting plate 8 synchronously with the second slider 117. When the second slider 117 is released, the second spring 118 will rebound and drive the insertion rod 115 to move to both sides through the second slider 117.
[0033] In a specific application scenario, firstly, pull the outermost limiting ring 52's pull block 510 upwards, causing the fixing rod 56 to slide upwards along the first slide groove 57 and compress the first spring 59. When the fixing rod 56 moves out of the fixing hole 54, slide the guide block 53 outwards along the guide groove 51 until the limiting ring 52 separates from the rotating shaft 4. Then, place the roll 2 around the rotating shaft 4 and position the drive block in the guide groove 51 until one end is tightly fitted with the innermost limiting ring 52. At this point, place the removed limiting ring 52 around the rotating shaft 4 in the same manner and make it tightly fitted with the other end of the roll 2. Then, release the pull block 510, and the first spring 59 rebounds and drives the fixing rod 56 downwards through the first slider 58. When the fixing rod 56 is inserted into the fixing hole 54 at the current position, the limiting ring 52 is fixed at the current position, thus limiting the roll 2. Then, place the roll under the pressure roller 10 so that the pressure roller 10... The material is pressed into the dipping tank 1. The motor 6 is started to drive the rotating shaft 4 to rotate. Since the drive block is slidably connected to the guide groove 51, the rotating shaft 4 will drive the roll material roller 2 to rotate synchronously, thus starting the dipping process. When the roll material tension is too high or too low, the second slider 117 slides along the second slide groove 116 toward the center of the mounting plate 8 to squeeze the second spring 118. During this process, the insertion rod 115 moves synchronously toward the center of the mounting plate 8 with the second slider 117. When the insertion rod 115 moves out of the insertion hole 113, the adjusting block 112 slides along the adjusting groove 111 to drive the pressure roller 10 to rise and fall through the mounting plate 8. When the pressure roller 10 rises and falls to the appropriate height, the second slider 117 is released. The second spring 118 rebounds and drives the insertion rod 115 to move to both sides through the second slider 117. When the insertion rod 115 is inserted into the insertion hole 113 at the current height, the pressure roller 10 can be fixed at the current height, thus completing the adjustment of the roll material tension.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
