Description

Technical Field

[0001] This utility model relates to the field of automotive cover production technology, specifically to a composite film lamination and bubble extrusion device for automotive cover production. Background Technology

[0002] In the production of car covers, laminating multiple layers of functional films (such as base film, adhesive layer, and protective film) is a crucial lamination process. However, during lamination, air can easily get trapped between the film layers, forming bubbles. Therefore, it is necessary to squeeze out these bubbles, which requires the use of bubble-squeezing equipment.

[0003] However, traditional rigid scrapers or blades have a fixed angle when debubbling, and cannot be adaptively adjusted according to the actual thickness or surface condition of the film. If the scraper angle is too steep, it is easy to scratch or even cut the soft film material; if the angle is too flat, it cannot effectively cut into the bottom of the bubble and scrape it off. Therefore, a composite film layer pressing and bubble extrusion device for automotive cover production is needed to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a composite film lamination and bubble extrusion device for automobile cover production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A composite film lamination and bubble extrusion device for producing car covers includes a base plate, a bubble removal assembly, and a lamination assembly. A first gantry frame is mounted on the top of the base plate, and a first electric push rod is mounted on the top of the first gantry frame. The bubble removal assembly includes a first rectangular block, which is installed at the output end of the first electric push rod. Mounting rods are respectively provided at the lower ends of both ends of the first rectangular block, and protrusions are fitted onto the two mounting rods. Rectangular strips are provided at the bottom ends of the two protrusions, and scrapers are provided at the bottom ends of the rectangular strips. Second rectangular blocks are respectively provided at the upper ends of both ends of the first rectangular block. Rectangular grooves are respectively opened at one end of each of the two second rectangular blocks, and L-shaped connecting rods are fitted inside the rectangular grooves. Vertical plates are provided at the bottom ends of the L-shaped connecting rods, and bearings are provided on the vertical plates. Threaded rods are provided in the bearings. Threaded holes are respectively opened at one end of each of the two protrusions, and one end of the threaded rod is fitted into the threaded hole.

[0006] As a preferred embodiment of this utility model, each of the two protrusions has a rotating hole at one end facing the other. The protrusions are fitted onto the mounting rod through the rotating holes, and the mounting rod and the rotating holes form a pivot point for rotation, thus providing a physical basis for the adjustment of the blade angle.

[0007] As a preferred embodiment of this utility model, limiting grooves are provided on both sides of the rectangular groove, and sliders are provided on both sides of the other end of the L-shaped connecting rod. The two sliders are respectively engaged in the two limiting grooves. The engagement of the sliders and the limiting grooves ensures that the L-shaped connecting rod can only make strict linear movements in the vertical direction.

[0008] As a preferred embodiment of this utility model, the other end of the threaded rod is provided with a knob, which serves as a manual operation interface for rotating the threaded rod.

[0009] As a preferred embodiment of this utility model, the pressing assembly includes a connecting plate, a second gantry frame on the top of the base plate, and a second electric push rod on the top of the second gantry frame. The output end of the second electric push rod is connected to the top of the connecting plate. The second gantry frame is the supporting frame of the pressing assembly. The second electric push rod is its power source, controlling the overall lifting and lowering of the pressing roller.

[0010] As a preferred embodiment of this utility model, the top two ends of the connecting plate are provided with through holes, and stepped rods are fitted into the two through holes. The bottom ends of the two stepped rods are connected to bearing seats, and a pressing roller is provided between the two bearing seats. The stepped rods serve as guide rods to ensure that the bearing seats and the pressing rollers can only move in the vertical direction. The pressing rollers are installed in the bearing seats and can rotate freely.

[0011] As a preferred embodiment of this utility model, a spring is sleeved on the outside of the stepped rod. The spring can provide a relatively constant additional pressure, which is superimposed on the main pressure of the electric push rod to ensure a uniform pressing effect. Placement slots are respectively opened at both ends of the bottom of the connecting plate. The placement slots are connected to the through holes. One end of the spring is connected to the inner wall of the placement slot, and the other end is connected to the top of the bearing seat.

[0012] As a preferred embodiment of this utility model, a pressing platform is provided on the top of the base plate. The pressing platform is located below the bubble removal component and the pressing component. The pressing platform is a planar working area for directly performing film layer pressing and defoaming operations.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, rotating the knob drives the threaded rod to rotate, which in turn drives the L-shaped connecting rod to slide within the rectangular groove. This causes one end of the threaded rod to move out of the threaded hole, releasing the fixed limit on the protrusion and thus releasing the fixed limit on the scraper. Then, rotating the scraper causes the protrusion to rotate around the axis of the mounting rod, achieving fine adjustment of the scraper's entry angle. This allows the equipment to adapt to films of different thicknesses, materials, or composite states. By finding the optimal entry angle, it ensures efficient removal of air bubbles while minimizing the risk of scratching or puncturing the precious film material due to improper angle.

[0014] 2. In this utility model, the pressing assembly adopts a spring buffer design. The continuous pressure applied by the spring keeps the pressing roller in close contact with the film surface, ensuring the uniformity of the initial pressing. The spring allows the pressing roller to be self-adaptively lifted to a certain extent through the step bar, forming a flexible pressure system, thereby avoiding film surface indentations or damage that may be caused by rigid pressing.

[0019] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A composite film lamination and bubble extrusion device for producing car covers includes a base plate 1, a bubble removal assembly 3, and a lamination assembly 5. The base plate 1 serves as the foundation of the entire device, supporting all other components. A first gantry frame 2 is mounted on top of the base plate 1, which is the supporting frame for the bubble removal assembly 3. A first electric push rod 201 is mounted on top of the first gantry frame 2, serving as its power source and providing vertical linear motion. The bubble removal assembly 3 includes a first rectangular block 301. Installed at the output end of the first electric push rod 201, the first rectangular block 301 serves as the core connector of this component, connecting the electric push rod above and hanging all the scraping mechanisms below. Mounting rods 3011 are respectively provided at the lower ends of the two ends of the first rectangular block 301, serving as pivots. Protrusions 3014 are fitted onto the two mounting rods 3011, acting as fulcrums for the entire angle adjustment function. Rectangular strips 3013 are provided at the bottom ends of the two protrusions 3014, connecting the protrusions 3014 and rectangular strips 3013 to the scraper 3012 and transmitting adjustment signals. To save energy, a scraper 3012 is provided at the bottom of the rectangular strip 3013. The scraper 3012 is a tool that directly contacts and removes air bubbles. Second rectangular blocks 302 are respectively provided at the upper parts of both ends of the first rectangular block 301. The second rectangular blocks 302 are fixed to the first rectangular block 301, providing an installation base. A rectangular groove 303 is provided at one end of each of the two second rectangular blocks 302. The rectangular groove 303 provides a channel and space for the linear movement of the L-shaped connecting rod 305. The L-shaped connecting rod 305 fits inside the rectangular groove 303. The bottom end of the L-shaped connecting rod 305 is provided with a vertical plate 307, which fixes the bearing 308 and connects the L-shaped connecting rod 305. The bearing 308 is provided on the vertical plate 307, and a threaded rod 309 is provided in the bearing 308. The bearing 308 supports the threaded rod 309 so that it can rotate smoothly and bear axial force. One end of each of the two protrusions 3014 is provided with a threaded hole 3016. One end of the threaded rod 309 is fitted in the threaded hole 3016. The threaded rod 309 and the threaded hole 3016 form a threaded locking mechanism.

[0020] In this embodiment, two protrusions 3014 are respectively provided with rotating holes 3015 at their opposite ends. The protrusions 3014 are engaged with the mounting rod 3011 through the rotating holes 3015.

[0021] In this embodiment, limiting grooves 304 are respectively provided on both sides of the rectangular groove 303, and sliders 306 are respectively provided on both sides of the other end of the L-shaped connecting rod 305. The two sliders 306 are respectively engaged in the two limiting grooves 304. The engagement of the sliders 306 and the limiting grooves 304 ensures that the L-shaped connecting rod 305 can only make strict linear movements in the vertical direction.

[0022] In this embodiment, a knob 3010 is provided at the other end of the threaded rod 309. The knob 3010 serves as an operating interface for rotating the threaded rod 309.

[0023] In this embodiment, the pressing assembly 5 includes a connecting plate 501, a second gantry 4 is provided on the top of the base plate 1, and a second electric push rod 402 is provided on the top of the second gantry 4. The output end of the second electric push rod 402 is connected to the top of the connecting plate 501. The second gantry 4 is the support frame of the pressing assembly 5. The second electric push rod 402 is its power source, controlling the overall lifting and lowering of the pressing roller 507.

[0024] In this embodiment, the top two ends of the connecting plate 501 are provided with through holes 502, and stepped rods 504 are fitted in the two through holes 502. The bottom ends of the two stepped rods 504 are connected to bearing seats 506, and a pressing roller 507 is provided between the two bearing seats 506. The stepped rods 504 serve as guide rods to ensure that the bearing seats 506 and the pressing roller 507 can only move in the vertical direction. The pressing roller 507 is installed in the bearing seat 506 and can rotate freely.

[0025] In this embodiment, a spring 505 is sleeved on the outside of the stepped rod 504. The spring 505 can provide a relatively constant additional pressure, which is superimposed on the main pressure of the electric push rod to ensure uniform pressing effect. The bottom ends of the connecting plate 501 are respectively provided with placement grooves 503, which are connected to the through hole 502. One end of the spring 505 is connected to the inner wall of the placement groove 503, and the other end is connected to the top of the bearing seat 506.

[0026] In this embodiment, a pressing platform 101 is provided on the top of the base plate 1. The pressing platform 101 is located below the bubble removal component 3 and the pressing component 5. The pressing platform 101 is a planar working area for directly performing film layer pressing and defoaming operations.

[0027] The working process of this utility model is as follows: When the composite film lamination and bubble extrusion equipment and structure for producing car covers designed in this scheme are in operation, the composite film that has been initially bonded but may contain air bubbles is laid flat on the lamination table 101 of the equipment. By rotating the knob 3010, the threaded rod 309 is rotated, which drives the L-shaped connecting rod 305 to slide in the rectangular groove 303. This causes one end of the threaded rod 309 to move out of the threaded hole 3016, releasing the fixed limit on the protrusion 3014, and thus releasing the fixed limit on the scraper 3012. Then, the scraper 3012 is rotated, thereby driving the protrusion 3014 to rotate around the axis of the mounting rod 3011. The optimal working angle can be finely adjusted in real time according to the softness and hardness of the film material, the viscosity of the adhesive, and the stubbornness of the air bubbles. After the angle adjustment is completed, the knob 3010 is rotated to drive the threaded rod 309 to rotate, so that it engages with the threaded hole 3016 for locking.

[0028] Then the first electric actuator 201 drives the bubble removal assembly 3 to descend, so that the leading edge of the scraper 3012 contacts the membrane surface at a certain angle, "scraping" up the remaining stubborn bubbles and guiding them to move along the shape of the scraper 3012 towards the edge of the membrane layer, and finally being completely discharged.

[0029] Then, the pressing assembly 5 is driven to descend as a whole by the second electric push rod 402, so that the pressing roller 507 contacts the film surface. Under the action of the spring 505, the pressing roller 507 applies a flexible and constant pressure, which helps to "iron" the tiny scratches left by the scraper 3012 and make the surface texture more uniform.

[0030] The first electric actuator 201 and the second electric actuator 402 used in this utility model are both existing known electrical devices, and both can be purchased and used directly on the market. Their structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the first electric actuator 201 and the second electric actuator 402 will not be described in detail here.

[0031] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
