Abstract
Description
Technical Field
[0001] This utility model relates to the field of pre-coated film curing technology, and more specifically, to a pre-coated film cold air curing device that can be concentrated in one direction. Background Technology
[0002] Pre-coated film curing refers to the process of applying adhesive to a plastic film and then cooling and curing it by blowing air onto it.
[0003] Existing air-cooling methods rely on fans to directly blow air onto the film, which is ineffective for cooling areas only applied to the sides of the plastic film. Furthermore, the airflow generated by the fans is too dispersed, failing to reach thicker areas of adhesive and thus hindering timely cooling and curing. Utility Model Content
[0004] The purpose of this invention is to provide a pre-coated film cold air curing device that can concentrate the direction of airflow, which solves the problems of existing air-cooling devices, where the airflow is too dispersed and cannot concentrate and cool the thicker local adhesive in time, and at the same time, it is impossible to control the direction of airflow and cannot target the adhesive that is only applied to the areas close to the sides of the plastic film.
[0005] This utility model is achieved through the following technical solution: This utility model provides a pre-coated film cold air curing device with a concentrated direction, including a main body, a conveyor belt arranged at the bottom of the middle part of the main body, a fan arranged at the top of the middle part of the main body, a first movable plate arranged at the top of the middle part of the main body, a guide surface arranged at the bottom of the first movable plate, a guide plate connected to the bottom of the guide surface, a second movable plate connected to the side of the top of the middle part of the main body away from the first movable plate, and sealing plates arranged on both sides of the middle part of the main body.
[0006] Preferably, the guide surface is a plate that extends to one side at the bottom of the first movable plate.
[0007] Preferably, the body also includes a slide groove, which is located at the top center of the body.
[0008] Preferably, the second movable plate is provided with a flow guiding surface and a guide plate, just like the first movable plate.
[0009] Preferably, the second movable plate further includes a slider, which is disposed on the top of the second movable plate. The second movable plate is connected to the slide groove via the top slider, and the top of the first movable plate is also connected to the slide groove via a slider.
[0010] Preferably, the guide surface further includes a bidirectional screw, which is rotatably connected to one end of the guide surface.
[0011] Preferably, the bidirectional screw thread passes through one end of the guide surface of the second movable plate and the first movable plate.
[0012] Preferably, the guide plate further includes a hinge shaft connected to the top of the guide plate, and the guide plate is connected to one end of the guide surface via the hinge shaft.
[0013] Preferably, the sealing plate also includes a through opening, and the sealing plate has a through opening in the middle.
[0014] Preferably, the through opening is fitted by a hinge shaft, and the sealing plate is attached to both ends of the second movable plate and the first movable plate.
[0015] The technical solution of this utility model has at least the following advantages and beneficial effects: 1. By separating and bringing the first movable plate and the second movable plate in the device together, the blown airflow can be limited and concentrated, and the range of the blown airflow can also be adjusted. This allows for both coordination with different pre-coated film application ranges and concentrated enhancement of airflow intensity.
[0016] 2. The device is also equipped with a guide plate, which can adjust the direction of the blown airflow to address situations where adhesive is applied only to different locations on the surface of the plastic film. Attached Figure Description

[0021] The following is combined Figures 1 to 3 This utility model will be described in detail.
[0022] A pre-coated film cold air curing device with a concentrated direction includes a body 1, a conveyor belt 101 at the bottom center of the body 1, a fan 102 at the top center of the body 1, a first movable plate 2 at the top center of the body 1, a guide surface 201 at the bottom of the first movable plate 2, a guide plate 203 connected to the bottom of the guide surface 201, a second movable plate 3 connected to the side of the top center of the body 1 away from the first movable plate 2, and sealing plates 4 on both sides of the middle center of the body 1.
[0023] First, the pre-coated plastic film is transported onto the conveyor belt 101 for transfer. Then, when it passes through the body 1, the top fan 102 blows air downwards to cure and cool the adhesive on the plastic film, making it easier to roll up.
[0024] Furthermore, the flow guiding surface 201 is a plate extending inclined to one side from the bottom of the first movable plate 2. The body 1 also includes a slide groove 103, which is located at the top of the middle part of the body 1. The second movable plate 3 is provided with the flow guiding surface 201 and the guide plate 203, just like the first movable plate 2. The second movable plate 3 also includes a slider 301, which is located at the top of the second movable plate 3. The second movable plate 3 is connected to the slide groove 103 through the top slider 301. The top of the first movable plate 2 is also connected to the slide groove 103 through the slider 301. The guide plate 203 also includes a hinge shaft 3031, which is connected to the top of the guide plate 203. The guide plate 203 is connected to one end of the flow guiding surface 201 through the hinge shaft 3031. The sealing plate 4 also includes a through opening 401, which is located in the middle of the sealing plate 4. The through opening 401 is connected to the hinge shaft 3031 through it, and the sealing plate 4 is attached to both ends of the second movable plate 3 and the first movable plate 2.
[0025] When the fan 102 blows air to cool and solidify, because the fan 102 is located between the second movable plate 3 and the first movable plate 2, the airflow will flow along the guide surface 201 and then be discharged between the two guide plates 203 at the bottom to limit the airflow and prevent the airflow from being too dispersed, which would prevent the thicker adhesive from being applied to the plastic film.
[0026] Then, when the pre-coated adhesive tape is applied to one side of the plastic film, and the dispersed blowing fan 102 cannot concentrate on it, the hinge shaft 3031 protruding through the through opening 401 is rotated by manual control, which drives the guide plate 203 to deflect. By controlling the second movable plate 3 and the guide plate 203 on the first movable plate 2 to deflect to one side, the direction of the airflow blown by the fan 102 is changed, thereby cooling the local adhesive near the plastic film. This avoids the problem that the airflow of the fan 102 cannot be concentrated and turned, which would cause the local adhesive on the plastic film to not cool and solidify in time, affecting the subsequent winding. At the same time, when the side wall of the hinge shaft 3031 penetrates the inner wall of the hole at one end of the guide surface 201, the two are tightly attached together, providing sufficient friction to ensure that the guide plate 203 will not deflect on its own, but will only move when manual force is applied.
[0027] Furthermore, the guide surface 201 also includes a bidirectional screw 202, which is rotatably connected to one end of the guide surface 201. The bidirectional screw 202 is threaded through the second movable plate 3 and one end of the guide surface 201 of the first movable plate 2.
[0028] Meanwhile, when the adhesive is thicker in certain areas and requires more concentrated airflow for cooling and curing, the bidirectional screw 202 can be rotated to move and close the second movable plate 3 and the first movable plate 2, thereby reducing the distance between the two guide plates 203, making the airflow more concentrated and increasing the airflow force. It can also enlarge the air vent to accommodate adhesive with a larger application area, making the airflow direction and range easier to control. The separation and closure of the second movable plate 3 towards the first movable plate 2 will not affect the deflection angle of the guide plate 203.
[0029] The following is a detailed implementation process of this utility model. First, the pre-coated plastic film is transported onto the conveyor belt 101 for transfer. Then, when it passes through the body 1, the top fan 102 blows air downwards to cure and cool the adhesive on the plastic film, so as to facilitate winding.
[0030] When the fan 102 blows air for cooling and curing, because the fan 102 is located between the second movable plate 3 and the first movable plate 2, the airflow will flow along the guide surface 201 and then be discharged between the two guide plates 203 at the bottom. This limits the airflow and prevents it from being too dispersed, which would prevent the application of a thicker layer of adhesive to only a small area of the plastic film. When the pre-coated adhesive film is applied to one side of the plastic film, and the dispersed blowing of the fan 102 cannot concentrate the application, the hinge shaft 3031 protruding through the through opening 401 is manually rotated to drive the guide plate 203 to deflect. By controlling the deflection of the guide plates 203 on the second movable plate 3 and the first movable plate 2 to one side, By changing the direction of the airflow blown by the fan 102, the adhesive on the side closest to the plastic film is cooled by air. This avoids the problem that the airflow of the fan 102 cannot be concentrated or directional, which would prevent the local adhesive on the plastic film from cooling and curing in time, thus affecting subsequent winding. At the same time, when the local adhesive is thick and requires more concentrated airflow for cooling and curing, the bidirectional screw 202 can be rotated to drive the second movable plate 3 and the first movable plate 2 to move and close, thereby reducing the distance between the two guide plates 203, making the airflow more concentrated and increasing the airflow force. It can also enlarge the air outlet to accommodate adhesive with a larger application area, making the direction and range of airflow easier to control. The separation and closure of the second movable plate 3 towards the first movable plate 2 will not affect the deflection angle of the guide plate 203.
