Description

Technical Field

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

[0002] Membrane material is the material used in membrane structure engineering. It is a composite material consisting of a high-strength fabric substrate and a polymer coating. The coating protects the substrate and forms the seal of the membrane material. The membrane material processing involves multiple steps, one of which is the application of adhesive.

[0003] A search revealed patent CN220634988U, which discloses "a film coating machine," comprising a base plate and a support frame. The support frame is fixedly connected to both sides of the base plate, and the top of both sides of the support frame is fixedly connected to the surface of the transmission frame. Transmission rollers are fixedly connected to both sides of the top of the support frame, and the outer surface of the transmission rollers is connected to the inner surface of the coating cloth. This device uses a reciprocating coating method, allowing the coating liquid to be evenly covered on the coating in a wave-like pattern. This eliminates concerns about uneven coating damage even when using a relatively rough brush for subsequent application. Furthermore, the reciprocating wave coating method avoids waste caused by repeated application of adhesive, effectively solving the problem of uneven coating while controlling the amount of adhesive used, thus making the coating operation more convenient.

[0004] In existing technologies, the membrane material is typically moved by guide rollers, and adhesive is applied to the surface of the membrane material during the movement. However, the membrane material is prone to deviation during the transport process. When the membrane material deviates, the coating pattern on the surface of the membrane material becomes tilted, which affects the aesthetics. Summary of the Invention

[0005] The purpose of this invention is to provide a membrane adhesive coating device that can limit and guide the membrane during its movement, preventing the membrane from shifting and causing the coating pattern to tilt, thus improving the coating effect.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a film material adhesive coating device, comprising: a frame, an adhesive tank installed on the top of the frame, a coating roller rotatably installed inside the adhesive tank, and a pressure roller arranged above the coating roller;

[0007] Two first limiting plates are arranged opposite each other on one side of the glue tank, and two second limiting plates are arranged opposite each other on the other side of the glue tank. The frame is provided with a sliding groove for the first limiting plates and the second limiting plates to slide together. The first limiting plates and the second limiting plates are symmetrically distributed about the glue tank. The first limiting plates and the second limiting plates on the same side each pass through the sliding groove and are connected to a movable plate. This movable plate is located below the frame, and the opposite movable plates are respectively sleeved on both ends of the bidirectional screw.

[0008] The following are further improvements to the above technical solution:

[0009] 1. In the above scheme, a fixing plate is installed at the bottom of the frame in a relatively opposite manner, and the bidirectional screw is rotatably installed between the two fixing plates in a manner parallel to the coating roller.

[0010] 2. In the above scheme, a guide rod that is slidably connected to the moving plate is provided on both sides of the bidirectional screw.

[0011] 3. In the above scheme, a second motor for driving the bidirectional screw to rotate is provided on one of the fixed plates.

[0012] 4. In the above scheme, a fixed frame is provided at the top of the frame, and a mounting base is elastically connected to the bottom of the fixed frame, and the lower pressure roller is rotatably installed inside the mounting base.

[0013] 5. In the above scheme, rubber pads are provided on the opposite sides of the two first limiting plates and the opposite sides of the two second limiting plates.

[0014] 6. In the above scheme, a fixed seat with an internal air expansion shaft is provided at the top of the frame, and the two first limiting plates are located between the fixed seat and the glue tank.

[0015] 7. In the above scheme, a pneumatic chuck is provided between the two ends of the air shaft and the fixed seat.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] This utility model relates to a membrane adhesive coating device, which has two first limiting plates arranged opposite each other on one side of the adhesive tank and two second limiting plates arranged opposite each other on the other side of the adhesive tank. The frame is provided with a sliding groove for the first and second limiting plates to slide together. The first and second limiting plates on the same side each pass through the sliding groove and are connected to a moving plate. The moving plate is located below the frame, and the opposite moving plates are respectively sleeved on both ends of a bidirectional screw. The rotation of the bidirectional screw drives the moving plate to move the limiting plates. The relative movement of the limiting plates on both sides can limit and guide the membrane during the movement of the membrane, avoid the membrane from deviating and causing the coating texture to tilt, and help improve the coating effect.

[0024] The two air shafts are disassembled by starting the chuck. The film material feed roll is placed on one air shaft and the take-up roll is placed on the other air shaft. The air shaft with the feed roll is installed in the fixed seat at the front position through the pneumatic chuck, and the air shaft with the take-up roll is installed in the fixed seat at the rear position through the pneumatic chuck. The film material on the feed roll passes between the pressure roller and the coating roller and then winds onto the take-up roll. The elastic element pushes the mounting seat under the action of elastic force, which drives the pressure roller to move downward. The pressure roller presses the film material onto the surface of the coating roller, and part of the coating roller is submerged in the glue in the glue tank.

[0025] Two first limiting plates 19 are arranged opposite each other on one side of the glue tank 7, and two second limiting plates 20 are arranged opposite each other on the other side of the glue tank 7. The frame 1 is provided with a sliding groove 10 for sliding connection of the first limiting plates 19 and the second limiting plates 20. The first limiting plates 19 and the second limiting plates 20 are symmetrically distributed about the glue tank 7. The first limiting plates 19 and the second limiting plates 20 on the same side each pass through the sliding groove 10 and are connected to a moving plate 17. The moving plate 17 is located below the frame 1, and the opposite moving plates 17 are respectively sleeved on both ends of the bidirectional screw 15.

[0026] The second motor is started to drive the second rotating shaft to rotate the bidirectional screw, which in turn drives the moving plate to move the first and second limiting plates. The relative movement of the first and second limiting plates on both sides realizes the limiting and anti-deviation of the film material. Then the second motor is stopped and the first motor is started. The first motor drives the air shaft with the take-up roll to rotate to realize the transfer of the film material. During the transfer, the coating roller rotates synchronously to realize the coating of adhesive.

[0027] A fixing plate 13 is mounted at the bottom of the frame 1 in a relatively opposite manner, and a bidirectional screw 15 is rotatably mounted between the two fixing plates 13 in a manner parallel to the coating roller 8.

[0034] The aforementioned bidirectional screw 15 is rotatably connected to the fixed plate 13 via a second rotating shaft 14.

[0035] Several elastic elements 22 are provided between the mounting base 11 and the fixing frame 9.

[0036] One of the aforementioned fixed bases 2 has a first motor 6 installed on its outer wall for driving the air shaft 5 to rotate.

[0037] The output shaft of the first motor 6 is fixedly connected to the first rotating shaft 3.

[0038] Example 2: A film material adhesive coating device, comprising: a frame 1, an adhesive tank 7 installed on the top of the frame 1, a coating roller 8 rotatably installed inside the adhesive tank 7, and a pressure roller 12 disposed above the coating roller 8;

[0039] Two first limiting plates 19 are arranged opposite each other on one side of the glue tank 7, and two second limiting plates 20 are arranged opposite each other on the other side of the glue tank 7. The frame 1 is provided with a sliding groove 10 for sliding connection of the first limiting plates 19 and the second limiting plates 20. The first limiting plates 19 and the second limiting plates 20 are symmetrically distributed about the glue tank 7. The first limiting plates 19 and the second limiting plates 20 on the same side each pass through the sliding groove 10 and are connected to a moving plate 17. The moving plate 17 is located below the frame 1, and the opposite moving plates 17 are respectively sleeved on both ends of the bidirectional screw 15.

[0040] The rotation of the bidirectional screw drives the moving plate to move the limiting plate. The relative movement of the limiting plates on both sides can limit and guide the film material during its movement, preventing the film material from shifting and causing the coating pattern to tilt, which is beneficial to improving the coating effect.

[0041] A fixing plate 13 is mounted at the bottom of the frame 1 in a relatively opposite manner, and a bidirectional screw 15 is rotatably mounted between the two fixing plates 13 in a manner parallel to the coating roller 8.

[0042] A guide rod 18 is provided on both sides of the aforementioned bidirectional screw 15, which is slidably connected to the movable plate 17.

[0043] A second motor 16 for driving the bidirectional screw 15 to rotate is provided on one of the aforementioned fixed plates 13.

[0044] A fixed frame 9 is provided on the top of the frame 1, and a mounting base 11 is elastically connected to the bottom of the fixed frame 9. The lower pressure roller 12 is rotatably installed inside the mounting base 11.

[0045] Rubber pads 21 are provided on the opposite sides of the two first limiting plates 19 and the opposite sides of the two second limiting plates 20.

[0046] A fixed seat 2 with an internal air expansion shaft 5 is provided at the top of the frame 1, and the two first limiting plates 19 are located between the fixed seat 2 and the glue tank 7.

[0047] A pneumatic chuck 4 is provided between the two ends of the air shaft 5 and the fixed base 2.

[0048] The working principle is as follows:

[0049] In use, first disassemble the two air shafts by starting the chuck. Put the film material feed roll on one air shaft and the take-up roll on the other air shaft. The air shaft with the feed roll is installed in the fixed seat at the front position through the pneumatic chuck, and the air shaft with the take-up roll is installed in the fixed seat at the rear position through the pneumatic chuck. The film material on the feed roll passes between the pressure roller and the coating roller and then winds onto the take-up roll. The elastic element pushes the mounting seat under the action of elastic force, which drives the pressure roller to move downward. The pressure roller presses the film material onto the surface of the coating roller, and part of the coating roller is submerged in the glue in the glue tank.

[0050] The second motor is started to drive the second rotating shaft to rotate the bidirectional screw, which in turn drives the moving plate to move the first and second limiting plates. The relative movement of the first and second limiting plates on both sides realizes the limiting and anti-deviation of the film material. Then the second motor is stopped and the first motor is started. The first motor drives the air shaft with the take-up roll to rotate to realize the transfer of the film material. During the transfer, the coating roller rotates synchronously to realize the coating of adhesive.

[0051] When the above-mentioned film adhesive coating device is used, the rotating bidirectional screw drives the moving plate to move the limiting plate. The limiting plates on both sides move relative to each other, thereby limiting and guiding the film during the movement of the film, avoiding the film from shifting and causing the coating pattern to tilt, which is beneficial to improving the coating effect.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
