Description

Technical Field

[0001] This utility model belongs to the field of PET film processing technology, and specifically relates to an oil-based adhesive coating device for PET film processing. Background Technology

[0002] PET film is a packaging film with relatively comprehensive performance. It has good transparency and gloss; it has good airtightness and aroma retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures.

[0003] Chinese patent application number 2022221489696 discloses a coating roller for PET film, including a glue storage tank and a coating roller mechanism with a disassembly / removal function. The coating roller mechanism has two sets of cylinders. When the coating roller needs to be disassembled, the two sets of cylinders simultaneously push two sets of receiving blocks. The receiving blocks move the glue storage tank downwards along the guide post, and the glue storage tank drives a limiting block to slide along the guide hole, causing the limiting block to disengage from the annular groove. This releases the limiting block from restricting a set of support shafts. As the glue storage tank moves downwards, the coating roller body completely detaches from the storage tank, and the distance between the storage tank and the PET film continuously increases. This not only facilitates the disassembly of the coating roller but also prevents the storage tank from burning the workers. Then, the entire coating roller assembly is pulled, causing the set of support shafts on the coating roller to disengage from the groove, allowing the coating roller to be removed directly, thus achieving disassembly of the coating roller.

[0004] The aforementioned patent lacks a cleaning function and cannot clean the membrane surface that needs to be coated with adhesive. Dust adhering to the membrane surface affects the subsequent coating quality. At the same time, the original device cannot monitor the amount of adhesive in the storage tank. When the level of adhesive in the storage tank is lower than the lower end of the coating roller, the adhesive in the storage tank cannot be coated onto the coating roller for subsequent coating work.

[0008] Preferably, the cleaning brush and the connecting plate are connected by a snap-fit ​​mechanism, and the spacing between adjacent rollers is the same.

[0009] Preferably, the monitoring components include a first horizontal plate, a folding rod, a float plate, a bottom plate, a second horizontal plate, a buzzer, a switch, and a stirring assembly. A float plate is installed on one side of the glue storage tank, a folding rod is fixed to the upper end of the float plate, and a bottom plate is fixed to the other end of the folding rod. A first horizontal plate is fixed to the upper side of one end of the glue storage tank at a position corresponding to the folding rod. A second horizontal plate is installed below the first horizontal plate, a buzzer is installed at the upper end of the second horizontal plate at a position corresponding to the bottom plate, and a switch is installed above the buzzer. Stirring assemblies are installed on both sides of the inside of the glue storage tank.

[0010] Preferably, the stirring assembly includes a motor, pulleys, a connecting belt, a main shaft, a secondary shaft, and stirring rods.

[0011] Preferably, the stirring rod on the secondary shaft is staggered from the float plate, and a sliding hole corresponding to the folding rod is provided in the first horizontal plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting up a cleaning component, allows the PET film to pass under several rollers between fixed plates. When the PET film is coated with glue, the cleaning brush on the connecting plate can clean the glue-coated surface of the lower end of the PET film. At the same time, the fan is turned on to send air into the fixed pipe through the air supply pipe. The air outlet on the fixed pipe can blow air onto the surface of the PET film that has been cleaned by the cleaning brush, thereby cleaning the surface of the PET film again. After that, the PET film is coated with glue. By setting up the cleaning component, the PET film can be cleaned, avoiding impurities adhering to the PET film and affecting the glue coating quality.

[0013] 2. This utility model, by setting up a monitoring component, allows the float to rise and fall with the glue level in the glue storage tank. The float drives the folding rod to slide in the horizontal plate. When the liquid level is lower than the lower end of the coating roller, the bottom plate at the other end of the folding rod contacts the switch at the upper end of the buzzer, thereby triggering the buzzer to alarm and prompt the staff to add glue to the glue storage tank. By setting up the monitoring component, the amount of glue in the glue storage tank can be monitored, avoiding the situation where the glue level is lower than the lower end of the coating roller, preventing the glue in the storage tank from being applied to the coating roller for subsequent coating work.

A fan 23 is installed on one side of the front end of one fixed plate 21. The fixed pipe 27 and the fan 23 are connected by an air supply pipe 26.

[0017] Specifically, the rotating roller 22 and the fixed plate 21 are rotatably connected by a shaft pin, and the upper end of the air outlet 28 is lower than the upper end of the cleaning brush 25.

[0018] By adopting the above technical solution, the roller 22 can rotate on the fixed plate 21, and the air outlet 28 will not scratch the PET film.

[0019] Specifically, the cleaning brush 25 is connected to the connecting plate 24 by a snap-fit, and the spacing between adjacent rotating rollers 22 is the same.

[0020] By adopting the above technical solution, the snap-fit ​​connection facilitates the removal and cleaning of the cleaning brush 25 from the connecting plate 24, and the several rotating rollers 22 can be distributed at equal intervals.

[0021] In this embodiment, when using the oil-based adhesive coating device for PET film processing, the device is installed in a suitable position, adhesive is injected into the adhesive storage tank 1, and the motor 25 is turned on to drive the coating roller 4 to rotate. The adhesive in the adhesive storage tank 1 is coated onto the coating roller 4. Then, the PET film can be passed over the coating roller 4.

When the PET film is coated with adhesive, the cleaning brush 25 on the connecting plate 24 can clean the adhesive surface of the lower end of the PET film. At the same time, the blower 23 is turned on to send air into the fixed pipe 27 through the air supply pipe 26. The air outlet 28 on the fixed pipe 27 can blow air onto the surface of the PET film after it has been cleaned by the cleaning brush 25, thereby cleaning the surface of the PET film again. After that, the PET film is coated with adhesive. By setting the cleaning component 2, the PET film can be cleaned to avoid impurities adhering to the PET film and affecting the coating quality. Example

[0022] The difference between this embodiment and embodiment 1 is that the monitoring component 3 includes a first horizontal plate 31, a folding rod 32, a float 33, a bottom plate 34, a second horizontal plate 35, a buzzer 36, a switch 37, and a stirring component 38. A float 33 is provided on one side of the interior of the glue storage tank 1. A folding rod 32 is fixed to the upper end of the float 33, and a bottom plate 34 is fixed to the other end of the folding rod 32. A first horizontal plate 31 is fixed to the upper side of one end of the glue storage tank 1 at a position corresponding to the folding rod 32. A second horizontal plate 35 is provided below the first horizontal plate 31. A buzzer 36 is installed at the upper end of the second horizontal plate 35 at a position corresponding to the bottom plate 34. A switch 37 is provided at the upper end of the buzzer 36. Stirring components 38 are provided on both sides of the interior of the glue storage tank 1.

[0023] By adopting the above technical solution, the float 33 rises and falls with the glue level in the glue storage tank 1. The float 33 drives the folding rod 32 to slide in the horizontal plate 31. When the liquid level is lower than the lower end of the coating roller 4, the bottom plate 34 at the other end of the folding rod 32 contacts the switch 37 at the upper end of the buzzer 36, thereby triggering the buzzer 36 to alarm and prompt the staff to add glue to the glue storage tank 1. By setting the monitoring component 3, the amount of glue in the glue storage tank 1 can be monitored to avoid the glue level being lower than the lower end of the coating roller 4, so that the glue in the glue storage tank 1 cannot be coated onto the coating roller 4 for subsequent glue coating work.

[0024] Specifically, the stirring assembly 38 includes a motor 381, a pulley 382, ​​a connecting belt 383, a main shaft 384, a secondary shaft 385, and stirring rods 386. The motor 381 is installed on the lower front side of the glue storage tank 1. The main shaft 384 is provided at the output end of the motor 381. The secondary shaft 385 is provided on one side of the main shaft 384. The pulleys 382 are fixed at the rear ends of both the secondary shaft 385 and the main shaft 384. The two pulleys 382 are connected by the connecting belt 383. Several stirring rods 386 are fixed on both the main shaft 384 and the secondary shaft 385.

[0025] By adopting the above technical solution, the motor 381 is turned on to drive the main shaft 384 to rotate. The main shaft 384 drives the secondary shaft 385 to rotate through the pulley 382 and the connecting belt 383. The rotation of the main shaft 384 and the secondary shaft 385 stirs the glue in the glue storage tank 1 through several stirring rods 386. By setting the stirring assembly 38, the glue in the glue storage tank 1 can be stirred to avoid the glue from settling or solidifying.

[0026] Specifically, the stirring rod 386 on the secondary shaft 385 is staggered from the float plate 33, and a sliding hole corresponding to the folding rod 32 is provided in the horizontal plate 31.

[0027] By adopting the above technical solution, the stirring rod 386 on the secondary shaft 385 is prevented from hitting the float plate 33, and the folding rod 32 can slide in the horizontal plate 31.

[0028] In this embodiment, by setting up the monitoring component 3, the float 33 rises and falls with the glue level in the glue storage tank 1. The float 33 drives the folding rod 32 to slide in the horizontal plate 31. When the liquid level is lower than the lower end of the coating roller 4, the bottom plate 34 at the other end of the folding rod 32 contacts the switch 37 at the upper end of the buzzer 36, thereby triggering the buzzer 36 to alarm and prompt the operator to add glue to the glue storage tank 1. By setting up the monitoring component 3, the amount of glue in the glue storage tank 1 can be monitored to prevent the glue level from falling below the lower end of the coating roller 4. At the end, the adhesive in the storage tank 1 cannot be applied to the coating roller 4 for subsequent coating work. By setting up the stirring assembly 38, the motor 381 is turned on to drive the main shaft 384 to rotate. The main shaft 384 drives the auxiliary shaft 385 to rotate through the pulley 382 and the connecting belt 383. The rotation of the main shaft 384 and the auxiliary shaft 385 stirs the adhesive in the storage tank 1 through several stirring rods 386. By setting up the stirring assembly 38, the adhesive in the storage tank 1 can be stirred to avoid the adhesive from settling or solidifying.

[0031] In this utility model, motor 25 is a previously disclosed technology, and the selected model is 5IK120GN-CF.

[0032] The blower 23 in this utility model is a previously disclosed technology, and the selected model is 4-72C.

[0033] The structure and working principle of the glue storage tank 1, the glue coating roller 4, and the motor 5 in this utility model have been disclosed in a PET film glue coating roller disclosed in Chinese patent application number 2022221489696. Its working principle is to inject glue into the glue storage tank 1, turn on the motor 5 to drive the glue coating roller 4 to rotate, and the glue in the glue storage tank 1 is coated onto the glue coating roller 4. Then the PET film can be passed over the glue coating roller 4. The rotation of the glue coating roller 4 can coat the PET film with glue.

[0034] The working principle and usage process of this utility model: When using the oil-based adhesive coating device for PET film processing, install the device in a suitable position, inject adhesive into the adhesive storage tank 1, turn on the motor 25 to drive the coating roller 4 to rotate, and the adhesive in the adhesive storage tank 1 is coated onto the coating roller 4. Then, the PET film can be passed over the coating roller 4. The rotation of the coating roller 4 can coat the PET film with adhesive. By setting the cleaning component 2, the PET film passes under several rotating rollers 22 between the fixed plates 21. When the PET film is coated with adhesive, the cleaning brush 25 on the connecting plate 24 can clean the adhesive surface of the lower end of the PET film. At the same time, the blower 23 is turned on to send air into the fixed pipe 27 through the air supply pipe 26. The air outlet 28 on the fixed pipe 27 can blow air onto the surface of the PET film after it has been cleaned by the cleaning brush 25, thereby cleaning the surface of the PET film again. After that, the PET film is coated with adhesive. By setting the cleaning component 2, the PET film can be cleaned to avoid impurities adhering to the PET film. To ensure the quality of glue application, a monitoring component 3 is installed. A float 33 rises and falls with the glue level in the glue tank 1. The float 33 drives a folding rod 32 to slide within a horizontal plate 31. When the glue level is lower than the lower end of the glue application roller 4, the bottom plate 34 at the other end of the folding rod 32 contacts the switch 37 at the upper end of the buzzer 36, triggering the buzzer 36 to alert the operator to add glue to the glue tank 1. The monitoring component 3 allows for the monitoring of the glue level in the glue tank 1, preventing the glue level from falling below the lower end of the glue application roller 4. If the adhesive in the storage tank 1 cannot be applied to the coating roller 4 for subsequent coating work, the stirring assembly 38 is set up. The motor 381 is turned on to drive the main shaft 384 to rotate. The main shaft 384 drives the auxiliary shaft 385 to rotate through the pulley 382 and the connecting belt 383. The rotation of the main shaft 384 and the auxiliary shaft 385 stirs the adhesive in the storage tank 1 through several stirring rods 386. By setting up the stirring assembly 38, the adhesive in the storage tank 1 can be stirred to prevent the adhesive from settling or solidifying.
