Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane production technology, and in particular to a waterproof membrane coating device. Background Technology

[0002] The main purpose of coating waterproof membranes is to protect the membrane from damage, extend its service life, and facilitate transportation and storage. The coating prevents the membrane from direct contact with moisture, dust, and other substances that may impair its properties.

[0003] Chinese Patent No. CN220742147U discloses a waterproof membrane laminating device, including a base and a laminating mechanism. A frame is mounted on the top of the base. A first laminating roller and a second laminating roller are mounted on the rear side of the inner wall of the frame, with the second roller located below the first roller. A tension adjustment mechanism is installed on the inner wall of the frame. Two sets of support blocks are mounted on the top of the base. A support frame is mounted on top of the support blocks. Both the first and second laminating rollers extend into the interior of the support frame. An extrusion assembly is installed on the inner wall of the support frame. This laminating device, by providing a laminating mechanism, facilitates the user's application of the waterproof membrane to the laminating film, and facilitates the extrusion of air bubbles between the waterproof membrane and the laminating film, thus ensuring a proper fit between them.

[0004] However, the above technical solution has the following shortcomings: Although the device adjusts the tension of the film by means of a tension adjustment mechanism, there is a height difference between the position of the roll material leaving the third pressure roller and the gap between the two film coating rollers when film coating is performed. This results in a difference in the pressure on the lower and upper surfaces of the roll material during film coating. In addition, the roll material is prone to lateral displacement during the conveying process, which affects the film coating effect of the roll material. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a waterproof membrane coating device. This device avoids the drawback of uneven stress on the upper and lower sides of the membrane during the coating process due to the conveying state, which affects the coating quality. It also restricts the lateral position of the membrane during conveying.

[0006] The present invention provides a waterproof membrane coating device, comprising a mounting base, a coating mechanism, and a limiting mechanism. The mounting base is provided with four front-to-back fixed blocks and a first upright frame, with limiting rollers and a membrane roller rotatably connected to the fixed blocks and the first upright frame, respectively. The coating mechanism includes two vertically distributed support frames on the mounting base, a cylinder mounted on the support frames, a first lifting seat driven by the cylinders, and a coating roller rotatably connected to the first lifting seat. The mounting base has a rectangular through hole. The limiting mechanism includes two horizontally distributed upright blocks on the mounting base, a threaded rod threadedly connected to the upright blocks, a limiting plate slidably connected to the mounting base, a bearing mounted on the limiting plate, and two guide rods mounted on the limiting plate. One end of the threaded rod is inserted into the inner hole of the bearing, and the guide rods are slidably connected to the upright blocks.

[0007] Preferably, a fixed plate is provided on the cylinder, and six fixed bolts arranged in a ring array are provided through the fixed plate. The fixed bolts are threadedly connected to the first lifting seat.

[0008] Preferably, the first lifting seat is provided with two sliders, and the mounting seat is provided with a vertical rod that is slidably connected to the sliders.

[0009] Preferably, a handle is provided at the end of the threaded rod away from the bearing, and a retaining ring is provided on the guide rod.

[0010] Preferably, two adjustment mechanisms are arranged on the upper front and rear of the mounting base. The adjustment mechanism includes two symmetrically distributed second uprights, a guide block slidably arranged on the second uprights, a second lifting seat arranged on the guide block, a top roller rotatably connected to the second lifting seat, and a drive assembly arranged on the mounting base.

[0011] Preferably, the drive assembly includes a rotating drum rotatably connected to the mounting base, a support column threadedly connected to the rotating drum, a motor mounted on the mounting base, a second gear driven by the motor, and a first gear coaxially mounted on the rotating drum, the first gear meshing with the second gear, and a second lifting seat mounted on the support column.

[0012] Preferably, two convex rings are coaxially arranged on the rotating drum, with both convex rings abutting against the mounting base.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. This utility model uses a limiting roller to keep the roll material horizontal when passing through the film and during lamination, avoiding uneven lamination pressure on the upper and lower sides due to height differences, which would affect the lamination effect. At the same time, the lamination mechanism adjusts the squeezing pressure of the two lamination rollers on the roll material and film according to the thickness of the roll material, ensuring that there are no wrinkles or unevenness on the lamination surface, and avoiding excessive pressure that could deform the film. It has good practicality.

[0015] 2. This utility model uses a limiting mechanism to adjust the position of the limiting plate on the mounting base according to the width of the roll material, so that the side of the roll material is restricted by the limiting plate during transportation, thereby preventing the roll material from shifting laterally during transportation and improving the quality of film coating.

[0021] Example 1

[0022] like Figure 1-Figure 4 As shown, the waterproof roll material coating device proposed in this embodiment includes a mounting base 1, a coating mechanism, and a limiting mechanism. The mounting base 1 is provided with four fixed blocks 2 distributed front to back and a first upright 4. Limiting rollers 3 and film rollers 5 are rotatably connected to the fixed blocks 2 and the first upright 4, respectively. The film rollers 5 are used to mount the film tube. The height of the roll material after being bonded and passing through the lower arc surface of the limiting rollers 3 is limited by the two limiting rollers 3, so that the roll material remains horizontal when passing through the film and being coated, avoiding different coating pressure on the upper and lower sides due to height difference, which would affect the coating effect.

[0023] like Figure 1 and Figure 2 As shown, the coating mechanism includes two support frames 6 distributed vertically on the mounting base 1, a cylinder 7 mounted on the support frame 6, a first lifting seat 9 driven and connected to the cylinder 7, and a coating roller 11 rotatably connected to the first lifting seat 9. The mounting base 1 is provided with a rectangular through hole.

[0024] A fixed plate 8 is provided on the cylinder 7. Six fixed bolts 10 arranged in a circular array are provided through the fixed plate 8. The fixed bolts 10 are threadedly connected to the first lifting seat 9. Two sliders 12 are provided on the first lifting seat 9. A vertical rod 13 is provided on the mounting seat 1 and is slidably connected to the sliders 12.

[0025] The cylinder 7 drives the first lifting seat 9 to move, and the first lifting seat 9 drives the coating roller 11 to move. This allows the two coating rollers 11 to adjust the pressure on the roll material and the film according to the thickness of the roll material. This ensures that the film is flatly adhered to the roll material, preventing wrinkles and unevenness on the coating surface, while also avoiding excessive pressure that could cause the film to stretch excessively and deform. This ensures the quality of the coating and has good practicality.

[0026] like Figure 1 and Figure 4 As shown, the limiting mechanism includes two upright blocks 23 distributed on the left and right sides of the mounting base 1, a threaded rod 24 threadedly connected to the upright blocks 23, a limiting plate 25 slidably connected to the mounting base 1, a bearing 26 set on the limiting plate 25, and two guide rods 27 set on the limiting plate 25. One end of the threaded rod 24 is inserted into the inner hole of the bearing 26, and the guide rod 27 is slidably connected to the upright blocks 23. A handle is provided at the end of the threaded rod 24 away from the bearing 26, and a retaining ring is provided on the guide rod 27.

[0027] By rotating the threaded rod 24 with the handle, the threaded rod 24 engages with the upright block 23, simultaneously driving the inner hole of the bearing 26 to rotate. Under the guidance of the guide rod 27, the threaded rod 24 drives the limiting plate 25 to move, thereby allowing the position of the limiting plate 25 on the mounting base 1 to be adjusted according to the width of the roll material. This ensures that the side of the roll material is restricted by the limiting plate 25 during transportation, preventing lateral deviation of the roll material during transportation and improving the quality of the coating.

[0028] Example 2

[0029] like Figure 1 and Figure 3 As shown, the waterproof membrane coating device proposed in this embodiment has two adjustment mechanisms arranged in front and behind the mounting base 1, compared with the first embodiment. The adjustment mechanism includes two symmetrically distributed second uprights 14, a guide block 19 slidably arranged on the second uprights 14, a second lifting seat 17 arranged on the guide block 19, a top roller 18 rotatably connected to the second lifting seat 17, and a drive assembly arranged on the mounting base 1.

[0030] The drive assembly includes a rotating drum 15 rotatably connected to the mounting base 1, a support column 16 threadedly connected to the rotating drum 15, a motor 21 mounted on the mounting base 1, a second gear 22 drivenly connected to the motor 21, and a first gear 20 coaxially mounted on the rotating drum 15. The first gear 20 meshes with the second gear 22, and a second lifting seat 17 is mounted on the support column 16.

[0031] Two convex rings are coaxially arranged on the rotating drum 15, and both convex rings abut against the mounting base 1. The convex rings are used to mount the rotating drum 15 on the mounting base 1.

[0032] In this embodiment, the first gear 20 and the second gear 22 are driven by the motor 21 to mesh and transmit power. The second gear 22 drives the rotating drum 15 to rotate. Due to the restriction of the movement direction of the second lifting seat 17 by the guide block 19, the rotating drum 15 will be screwed into the support column 16. Then the second lifting seat 17 can drive the top roller 18 to rise and fall, thereby adjusting the tension of the roll material during conveying and avoiding bending of the roll material, which would affect the quality of the coating.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. 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.
