Description

Technical Field

[0001] This utility model relates to the technical field of bubble removal devices, specifically a bubble removal device for butyl damping film extrusion. Background Technology

[0002] During the production of butyl damping film, air bubbles are generated inside. Before leaving the factory, the internal bubbles need to be removed. Currently, Chinese utility model patent with announcement number CN208411262U discloses an air bubble extrusion device, which includes a base. Two support plates are provided on the upper surface of the base. An active roller and a driven roller are rotatably arranged between the support plates. A drive motor for driving the active roller to rotate is provided on one side of the active roller. An adjustment groove is opened on the upper surface of the support plate. An adjustment block is slidably arranged in the adjustment groove and is rotatably connected to the driven roller.

[0003] An existing patent (publication number CN221908588U) discloses a device for extruding and removing air bubbles from butyl damping film. By setting up a cleaning roller, a support plate, a connecting rod and a scraper, the cleaning roller and scraper are used to remove foreign matter from the upper and lower surfaces of the butyl damping film, which can prevent the film from being damaged by foreign matter when the extrusion device extrudes the butyl damping film.

[0004] However, there are some problems with the existing de-bubbling device during use: 1. The current de-bubbling device is not convenient for precise pressing of films of different sizes, and the entire film needs to be pressed sequentially, which affects the efficiency of de-bubbling; 2. The existing de-bubbling device is not convenient for sending the cut film out of the device after the air bubbles are extruded, and the film needs to be removed manually, which affects the smoothness of continuous operation. Utility Model Content

[0005] The purpose of this invention is to provide a butyl damping film extrusion and bubble removal device to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, this utility model provides the following technical solution: including a base, a pushing assembly and an extrusion assembly, wherein the front end of the base is provided with a pushing assembly that can push out the clips after degassing air, upright plates are installed on the upper ends of both sides of the base, an electric hydraulic rod is installed inside the upright plate, a horizontal plate is installed at the lower end of the electric hydraulic rod, and an extrusion assembly that can be quickly replaced is provided on the lower side of the center of the horizontal plate;

[0007] The pushing assembly includes a telescopic groove, a telescopic plate is installed in the telescopic groove, a limit groove is opened on the side wall of the telescopic groove, a limit plate is installed on the side wall of the telescopic plate, a gear is installed at the upper end of the telescopic plate, and a motor is connected to the side wall of the gear.

[0008] The extrusion assembly includes a slot, in which an insert plate is inserted. The insert plate has an inner groove at its center. A first bevel gear is installed on the inner wall at the front end of the inner groove. A knob is connected to the front end of the first bevel gear. Second bevel gears are installed on the inner walls on both sides of the inner groove.

[0009] As a further improvement of this utility model: a top groove is provided at the upper end of the telescopic groove, a toothed plate is installed in the top groove, and a push plate is installed on the upper outer wall of the front end of the telescopic plate.

[0010] As a further embodiment of this utility model: slots are provided on the outer sides of both ends of the inner groove, a screw is installed in the slot, a retaining plate is fitted on the outer wall of the screw, retaining slots are provided on both sides of the slot, and a pressing block is installed at the lower end of the insert plate.

[0011] As a further improvement of this utility model, the cross-sectional dimensions of the limiting plate and the cross-sectional dimensions of the limiting groove are consistent with each other.

[0012] As a further improvement of this utility model, the toothed plate meshes with the gear.

[0013] As a further embodiment of this utility model, the first bevel gear and the second bevel gear mesh with each other.

[0014] As a further improvement of this utility model, the cross-sectional dimensions of the card slot match the cross-sectional dimensions of the card plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention involves turning a knob to rotate a first bevel gear, which in turn rotates a second bevel gear, causing the connected screw to rotate. This rotation causes the clamping plate to slide into the slot, disengaging it from the outer slot. Pulling down the extrusion block causes the insert plate to disengage from the slot. The insert plate of the required extrusion block is then inserted into the aligned slot. Turning the knob in the opposite direction causes the first bevel gear to reverse, which in turn rotates the second bevel gear and the screw, causing the clamping plate to slide outwards and into the aligned slot. Controlling the electric hydraulic rod to move downwards causes the replaced extrusion block to press down on the film, thereby expelling air bubbles from the film.

[0017] This utility model controls the motor to rotate the gears so that they mesh relative to each other on the surface of the gear plate. With the limiting plate embedded in the limiting groove, the telescopic plate moves into the telescopic groove, causing the upper push plate to slide backward against the base surface, quickly pushing the extruded film backward to complete the discharge. Then, the push plate is controlled to move forward to detach from the base surface, so that subsequent extrusion operations can be performed. Attached Figure Description

[0023] To facilitate the solution of the problem, this utility model provides a butyl damping film extrusion and air bubble removal device. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0024] like Figures 1 to 4As shown, this embodiment provides a butyl damping film extrusion and de-bubbling device, including a base 1, a pushing assembly 2, and an extrusion assembly 6. The base 1 has a pushing assembly 2 at its front end that can push out the de-bubbled film. Vertical plates 3 are installed on the upper ends of both sides of the base 1. An electro-hydraulic rod 4 is installed inside the vertical plate 3. A horizontal plate 5 is installed at the lower end of the electro-hydraulic rod 4. A quickly replaceable extrusion assembly 6 is located on the lower center of the horizontal plate 5. The pushing assembly 2 includes a telescopic groove 201. A telescopic plate 202 is installed inside the telescopic groove 201. A limiting groove 203 is formed on the side wall of the telescopic groove 201. A limiting plate 204 is installed on the side wall of the telescopic plate 202. A gear 205 is installed on the upper end of the telescopic plate 202. The side wall of the gear 205 is connected to… A motor 206 is connected to quickly push the film after the air bubbles have been squeezed out backward to complete the discharge. Then, the push plate 209 is controlled to move forward and detach from the surface of the base 1, so that the subsequent air bubble squeezing operation can be performed. The squeezing component 6 includes a slot 601, in which an insert plate 602 is inserted. The insert plate 602 has an inner groove 603 in the center. A first bevel gear 604 is installed on the inner wall of the front end of the inner groove 603. A knob 605 is connected to the front end of the first bevel gear 604. A second bevel gear 606 is installed on the inner walls of both sides of the inner groove 603. The engagement drives the clamping plate 609 to slide outward and insert into the aligned clamping slot 610. The electric hydraulic rod 4 is controlled to move down and drive the replaced squeezing block 611 to press down and squeeze the film, thereby realizing the air bubble discharge of the film. Example

[0025] In addition to all the technical features in Embodiment 1, this embodiment also includes: a top groove 207 is provided at the upper end of the telescopic groove 201, a toothed plate 208 is installed in the top groove 207, and a push plate 209 is installed on the upper outer wall of the front end of the telescopic plate 202. By controlling the push plate 209 to move forward and disengage from the surface of the base 1, the subsequent bubble squeezing operation can be performed.

[0026] Furthermore, slots 607 are provided on the outer sides of both ends of the inner groove 603, and a screw 608 is installed in the slot 607. A retaining plate 609 is fitted on the outer wall of the screw 608. A retaining groove 610 is provided on both sides of the slot 601. An extrusion block 611 is installed at the lower end of the insert plate 602. The electric hydraulic rod 4 moves down and drives the replaced extrusion block 611 to press down and squeeze the film, thereby realizing the treatment of air bubbles in the film.

[0027] Furthermore, the cross-sectional dimensions of the limiting plate 204 match the cross-sectional dimensions of the limiting groove 203. With the limiting plate 204 embedded in the limiting groove 203, the telescopic plate 202 moves towards the inside of the telescopic groove 201, causing the upper push plate 209 to slide backward against the surface of the base 1.

[0028] Furthermore, the toothed plate 208 meshes with the gear 205, and the rotation of the gear 205 causes it to mesh relative to the surface of the toothed plate 208 to achieve efficient displacement and propulsion.

[0029] Furthermore, the first bevel gear 604 and the second bevel gear 606 mesh with each other. When the first bevel gear 604 rotates, the meshing causes the second bevel gear 606 to rotate, which in turn causes the connected screw 608 to rotate.

[0030] Furthermore, the cross-sectional dimensions of the slot 610 match the cross-sectional dimensions of the card plate 609, causing the card plate 609 to slide outward and insert into the aligned slot 610, thus achieving a firm and stable fixation.

[0031] Working principle: Twisting knob 605 rotates the first bevel gear 604, which in turn rotates the second bevel gear 606, causing the connected screw 608 to rotate. This rotation causes the clamping plate 609 to slide into the slot 607, disengaging it from the outer slot 610. Pulling down the pressing block 611 causes the insert plate 602 to disengage from the slot 601. Insert the insert plate 602 at the upper end of the pressing block 611 of the required model into the aligned slot 601. Twisting knob 605 in the opposite direction rotates the first bevel gear 604, which in turn rotates the second bevel gear 606, causing the screw 608 to rotate in reverse, thus rotating the clamping plate 609. 9. Slide outward into the aligned slot 610, control the electric hydraulic rod 4 to move down and drive the replaced extrusion block 611 to press down and extrude the film, thereby achieving the air bubble removal process of the film. Control the motor 206 to run and drive the gear 205 to rotate so that they mesh relative to each other on the surface of the toothed plate 208. Under the limit of the limiting plate 204 embedded in the limiting groove 203, the telescopic plate 202 moves towards the inside of the telescopic groove 201, driving the upper push plate 209 to slide backward and close to the surface of the base 1, pushing the film with the extruded air bubble quickly backward to complete the discharge. Then control the push plate 209 to move forward and disengage from the surface of the base 1, so that the subsequent air bubble extrusion operation can be performed.
