Description

Technical Field

[0001] This utility model relates to the technical field of cleaning and dust removal devices, specifically a cleaning and dust removal device for the surface of automotive TPU car cover substrate. Background Technology

[0002] During the production process of automotive TPU car cover substrates, dust, fibers, and tiny particulate impurities from the environment and production processes easily adhere to their surface. If these impurities are not effectively removed, they will directly affect the quality of subsequent coating and lamination processes, leading to bubbles, defects, and even reducing the protective performance and lifespan of the car cover. Therefore, cleaning and dust removal of the substrate surface is a crucial preliminary step in the TPU car cover production process. Currently, the industry uses adhesive roller cleaning devices to clean the surface of TPU car cover substrates. These devices remove impurities by rolling the adhesive roller into contact with the substrate surface and using the adhesive material on the roller surface. They are simple to operate and have stable cleaning effects, making them one of the dust removal solutions.

[0003] Existing adhesive roller cleaning devices have the following key drawbacks in practical applications, specifically:

[0004] After a period of use, the surface stickiness of the adhesive roller will decrease due to the adsorption of impurities, and it must be replaced. When replacing the existing equipment, the conveying of the substrate and the production process must be suspended. The equipment can only be restarted after the new adhesive roller is installed and debugged. Stopping the machine to replace the roller will significantly reduce the overall operating efficiency of the equipment and increase the production time cost per unit product. Therefore, in order to solve the above problems, a surface cleaning and dust removal device for automotive TPU car cover substrate is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a device for cleaning and removing dust from the surface of automotive TPU car cover substrate, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for cleaning and removing dust from the surface of automotive TPU car cover substrate includes a workbench and a positioning mechanism, wherein a mounting bracket is fixed on the workbench.

[0008] A rotating shaft is rotatably mounted on the mounting frame. Both ends of the rotating shaft pass through the side plate of the mounting frame and are fixed with connecting shafts. A rotating plate is fixed on the connecting shafts.

[0009] Both ends of the mounting frame are fixed with V-shaped frames, and both ends of the two V-shaped frames are detachably mounted with sticky rollers via positioning mechanisms.

[0010] Both ends of the outer wall of the mounting bracket are rotatably connected to electric push rods, and the moving end of the electric push rod is rotatably connected to the outer surface of the connecting shaft.

[0011] As a preferred embodiment of this utility model, an upper baffle and a lower baffle are fixed at both ends of the outer wall of the mounting bracket, and an arc-shaped groove is provided on both the upper baffle and the lower baffle, and a silicone pad is provided in the arc-shaped groove.

[0012] The above technical solution, by setting up upper and lower baffles with arc grooves and silicone pads, can limit the rising angle and working angle of the sticky roller, avoid excessive squeezing or incomplete separation between the sticky roller and the substrate due to the deviation of the electric push rod stroke, and the silicone pad can buffer the collision between the connecting shaft and the baffle, reduce mechanical noise, protect metal parts from impact damage, and extend the service life of the device.

[0013] As a preferred embodiment of this utility model, both ends of the V-shaped frame are fixed with fixing rods, and semi-circular grooves are opened on the fixing rods, and both ends of the sticky roller rotate on the semi-circular grooves.

[0014] Through the above technical solution, the semi-circular groove of the fixing rod matches the rotating shaft of the sticky roller, providing stable rotation support for the sticky roller. The wear-resistant fixing rod and the smooth semi-circular groove can reduce the frictional resistance when the sticky roller rotates, avoid the generation of debris due to friction to contaminate the substrate, and ensure stable cleaning effect.

[0015] As a preferred embodiment of this utility model, the positioning mechanism includes a fixed frame, with both ends of the fixed frame fixed to one side of two V-shaped frames respectively. A screw rod is threaded through the middle end of the fixed frame, and a connecting frame is rotatably connected to the bottom of the screw rod. Limiting rods are fixed at both ends of the connecting frame, and the limiting rods are clearance-fitted with the fixed frame. An arc-shaped plate is fixed at the bottom of the limiting rod, and the arc-shaped plate cooperates with the fixed rod.

[0016] The fixing frame is shaped like an inverted "U". A threaded hole is opened through the middle of the fixing frame. The threaded hole is threaded with the screw. A rotating handle is fixed to the top of the screw.

[0017] Through the above technical solution, the clearance fit between the perforation and the limiting rod restricts the lateral displacement of the connecting frame, ensuring that the arc plate is always aligned with the rotating shaft of the dust-sticking roller, avoiding uneven pressing caused by positioning deviation. The "T"-shaped limiting rod can prevent the limiting rod from falling off the perforation.

[0018] As a preferred embodiment of this utility model, both ends of the top of the fixing frame are provided with through holes, and the through holes are fitted with the limiting rod with clearance. The limiting rod is T-shaped.

[0019] As a preferred solution of the present utility model, the connecting bracket is in an inverted "V" shape, and through holes are formed through both ends of the connecting bracket, and the through holes are in interference fit with the limiting rods.

[0020] Through the above technical solution, the interference fit between the through hole and the limiting rod ensures the synchronous movement of the two, avoids positioning failure caused by looseness, and improves the stability of the mechanism.

[0021] As a preferred solution of the present utility model, guide assemblies are respectively fixed at the two ends of the mounting bracket on the top of the worktable. The guide assembly comprises support rods fixed at the two ends of the top of the worktable, and a guide roller with a polyurethane layer is rotationally connected between the two support rods through a bearing.

[0022] Through the above technical solution, the polyurethane layer of the guide roller can reduce frictional damage to the TPU substrate and provide proper tension, ensuring smooth conveying of the substrate.

[0023] Compared with the prior art, the beneficial effects of the present utility model are:

[0024] 1. The present utility model adopts a structural design of a mounting bracket, a rotating shaft, a V-shaped bracket, a dust-binding roller and an electric push rod. By arranging two groups of left and right dust-binding rollers and cooperating with the electric push rod to achieve alternate position switching, when one group of dust-binding rollers needs to be replaced due to adsorbed impurities, the electric push rod can lift it to a non-working position, and simultaneously lower another group of standby dust-binding rollers to the working position to contact the substrate, which realizes the synchronization of dust-binding roller replacement and substrate cleaning operation, ensures that the production process of TPU car film substrate is not interrupted, and effectively guarantees the working efficiency.

[0025] 2. The present utility model adopts a structural design of a fixing frame, a screw rod, a connecting bracket, a limiting rod and arc-shaped plates. When the dust-binding roller to be replaced needs to be disassembled, rotating the screw rod enables the connecting bracket to drive the arc-shaped plates at both sides to rise synchronously, so the limit on the dust-binding roller can be released, and the staff can quickly take out and replace the dust-binding roller to be replaced. The operation is simple and fast, which helps the staff quickly complete the disassembly and replacement of the dust-binding roller. Description of Drawings

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0033] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0034] A device for cleaning and removing dust from the surface of automotive TPU car cover substrate includes a workbench 1 and a positioning mechanism 8, with a mounting bracket 2 fixed on the workbench 1.

[0035] A rotating shaft 3 is rotatably mounted on the mounting bracket 2. Both ends of the rotating shaft 3 pass through the side plate of the mounting bracket 2 and are fixed with connecting shafts 30. A rotating plate 31 is fixed on the connecting shaft 30.

[0036] Both ends of the mounting bracket 2 are fixed with V-shaped brackets 4, and both ends of the two V-shaped brackets 4 are detachably mounted with dust rollers 5 through positioning mechanisms 8.

[0037] Electric push rods 6 are rotatably connected to both ends of the outer wall of the mounting bracket 2, and the moving end of the electric push rod 6 is rotatably connected to the outer surface of the connecting shaft 30.

[0038] Among them, the electric push rod 6 adopts a servo electric push rod. Its cylinder end is rotatably connected to the outer wall of the mounting bracket 2 through a hinge seat, and the moving end (piston rod) is rotatably connected to the outer surface of the connecting shaft 30 through a fisheye bearing. The fisheye bearing can compensate for the angular deviation during the rotation process, reduce the lateral force on the electric push rod 6, and extend its service life. The servo control can realize the precise adjustment of the push rod stroke and ensure the position accuracy when the two cleaning mechanisms are switched.

[0039] In this embodiment, an upper baffle 7 and a lower baffle 70 are fixed at both ends of the outer wall of the mounting bracket 2, and an arc-shaped groove is provided on both the upper baffle 7 and the lower baffle 70, and a silicone pad is provided in the arc-shaped groove.

[0040] Through the above technical solution, by setting the upper baffle 7 with arc groove and the lower baffle 70 with silicone pad, the lifting angle and working angle of the sticky roller 5 can be limited, avoiding excessive squeezing or incomplete separation of the sticky roller 5 and the substrate due to the travel deviation of the electric push rod 6. The silicone pad can buffer the collision between the connecting shaft 30 and the baffle, reduce mechanical noise, and protect the metal parts from impact damage, thus extending the service life of the device.

[0041] In this embodiment, both ends of the V-shaped frame 4 are fixed with fixing rods 40, and semi-circular grooves 41 are provided on the fixing rods 40. The two ends of the dust-adhesive roller 5 rotate on the semi-circular grooves 41.

[0042] The V-shaped frame 4 is made of two high-strength alloy rods welded at a 90° angle. Its top end is fixed to the rotating plate 31, and the bottom ends are respectively welded with fixed rods 40. The fixed rods 40 are cylindrical structures made of wear-resistant stainless steel. A semi-circular groove 41 is opened on its top, and the groove is smooth (Ra≤0.8μm) to ensure that the dust roller 5 can rotate freely along the semi-circular groove 41, while avoiding friction scratches between it and the fixed rods 40.

[0043] Through the above technical solution, the semi-circular groove 41 of the fixing rod 40 is matched with the rotating shaft of the sticky roller 5, providing stable rotation support for the sticky roller 5. The wear-resistant fixing rod 40 and the smooth semi-circular groove 41 can reduce the frictional resistance when the sticky roller 5 rotates, avoid the generation of debris due to friction to contaminate the substrate, and ensure stable cleaning effect.

[0044] In this embodiment, the positioning mechanism 8 includes a fixed frame 80, with both ends of the fixed frame 80 fixed to one side of two V-shaped frames 4 respectively. A screw 81 is threaded through the middle end of the fixed frame 80, and a connecting frame 82 is rotatably connected to the bottom of the screw 81. Limiting rods 83 are fixed at both ends of the connecting frame 82. The limiting rods 83 are clearance-fitted with the fixed frame 80, and an arc-shaped plate 84 is fixed at the bottom of the limiting rod 83. The arc-shaped plate 84 cooperates with the fixed rod 40.

[0045] The fixing frame 80 is in an inverted U-shape, a threaded hole is opened through the middle end of the fixing frame 80, the threaded hole is in threaded fit with a screw rod 81, and a rotating handle is fixed on the top of the screw rod 81.

[0046] Through the above technical solution, the clearance fit between the through hole and the limit rod 83 limits the lateral displacement of the connecting frame 82, ensures that the arc-shaped plate 84 is always aligned with the rotating shaft of the dust-binding roller 5, avoids uneven pressing caused by positioning deviation, and the T-shaped limit rod 83 can prevent the limit rod 83 from falling off from the through hole.

[0047] Wherein, in order to reduce the friction force when the dust-binding roller 5 rotates, bearing bushes can be arranged in the arc-shaped plate 84 and the semicircular groove 41 according to actual requirements.

[0048] In this embodiment, through holes are opened through both ends of the top of the fixing frame 80, the through holes are in clearance fit with the limit rod 83, and the limit rod 83 is T-shaped.

[0049] In this embodiment, the connecting frame 82 is in an n-shape, through holes are opened through both ends of the connecting frame 82, and the through holes are in interference fit with the limit rod 83.

[0050] Through the above technical solution, the interference fit between the through hole and the limit rod 83 ensures synchronous movement of the two, avoids positioning failure caused by looseness, and improves the stability of the mechanism.

[0051] In this embodiment, guide assemblies 9 for guiding the TPU car film base material are respectively fixed at both ends of the mounting frame 2 on the top of the worktable 1, the guide assembly 9 includes support rods fixed at both ends of the top of the worktable 1, and a guide roller is rotatably connected between the two support rods through a bearing.

[0052] Wherein, the guide assemblies 9 are symmetrically distributed at the feeding end and the discharging end of the mounting frame 2, and the guide roller is a seamless steel pipe externally coated with a polyurethane layer.

[0053] Through the above technical solution, the polyurethane layer of the guide roller can reduce friction damage to the TPU base material, and provide proper tension at the same time to ensure smooth conveying of the base material.

[0054] Working process of the present utility model: when the automobile TPU car film base material surface cleaning and dust removing device designed by the present scheme is in operation:

[0055] The sticky roller 5 at the working position rotates synchronously with the substrate under the action of the substrate friction force. It removes dust, fibers and other impurities from the surface of the TPU car cover substrate by surface adhesion. When the surface adhesion of the sticky roller 5 at the working position decreases and needs to be replaced, the control switch starts the electric push rod 6. The piston rod of the electric push rod 6 extends (or shortens) and pushes the connecting shaft 30 to rotate around the rotating shaft 3, which drives the V-shaped frame 4 and the sticky roller 5 to rotate synchronously: the sticky roller 5 at the original working position rises and the sticky roller 5 at the original standby position descends to contact the TPU car cover substrate.

[0056] The old sticky roller 5, which is in the standby position, is completely separated from the substrate. The operator rotates the rotating handle of the positioning mechanism 8, and the screw 81 drives the arc plate 84 to rise, loosening the fixation on the sticky roller 5. The old sticky roller 5 is taken out from the semi-circular groove 41 of the fixing rod 40. After inserting the new sticky roller 5, the operator rotates the handle in the opposite direction, and the arc plate 84 is aligned with the rotating shaft of the sticky roller 5 to complete the replacement.

[0057] The electric push rod 6 used in this utility model is an existing known electrical device, and all of them can be purchased and used directly on the market. Its structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the electric push rod 6 will not be described in detail here.

[0058] 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.

[0059] 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.
