Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile film production, and specifically relates to a positioning mechanism for automobile film production cutting. BACKGROUND

[0002] Automobile film, also commonly known as solar film or explosion-proof heat insulation film, is a kind of automobile accessory widely used. Its main function is to be attached to the front and rear windshields, side windows and skylights of a vehicle. In practical applications, automobile film exhibits a series of important functions: it can effectively block heat and sunlight, significantly reducing the high temperature inside the vehicle caused by direct sunlight; it has excellent blocking ability to ultraviolet rays, protecting the people inside the vehicle from ultraviolet damage; it has safety and explosion-proof properties, preventing secondary damage caused by glass splashing when the glass is broken by external force; it can create a private space to protect the privacy of people inside the vehicle; it can help reduce air conditioning energy consumption and improve vehicle energy utilization efficiency; from the perspective of aesthetics, it can make the appearance of the vehicle more coordinated and unified; it can also effectively prevent glare and improve driving safety.

[0003] According to the search, the patent application No. CN222003649U discloses a positioning mechanism for automobile film production cutting. Although the device makes the bottom of the extrusion rod contact the surface of the automobile film during use, and positions the automobile film through the cooperation of the limiting parts to prevent movement or curling during shearing, it improves the shearing precision and the aesthetic degree of the automobile film to a certain extent. However, the device lacks a reliable limiting mechanism during the upper link, and the automobile film is prone to deviation, which not only affects the cutting precision, but also may cause size deviation of the cut product, which cannot meet the installation requirements. Moreover, the debris generated during the cutting process often adheres to the surface of the film body, and if not thoroughly cleaned, these debris will seriously affect the film pasting operation, causing uneven film pasting, air bubbles and other problems. UTILITY MODEL CONTENTS

[0004] In view of the deficiencies of the prior art, the utility model provides a positioning mechanism for automobile film production cutting, which solves the problems raised in the background art.

[0005] The solution of the utility model to the above technical problems is as follows:

[0006] A positioning mechanism for automobile film production cutting, comprising a cutting machine body, a first drive motor is provided on the cutting machine body, a cutting blade is installed on the output shaft of the first drive motor, a pay-off wheel is installed on the cutting machine body, and an automobile film body is connected to the pay-off wheel;

[0007] The cutting machine body is internally provided with a mounting rack and a cutting platform, the mounting rack is provided with a hydraulic rod, the cutting platform is provided with a support, the support is provided with a guide rod and a second driving motor, and the output shaft of the second driving motor is provided with a lead screw.

[0008] The rear end surface of the cutting machine body is provided with a third driving motor through a fixing frame, and the fixing frame is fixedly provided with a gas collecting cover.

[0009] On the basis of the above technical scheme, the utility model further can make improvement as follows.

[0010] Further, the front end surface of the cutting machine body is provided with a guide shaft through a connecting frame, and the guide shaft limits the automobile film body.

[0011] The beneficial effects of the above further scheme are:

[0012] The guide shaft can effectively limit the automobile film body during the conveying process from the unwinding wheel to the cutting platform, so that the automobile film can maintain a stable position and direction during the conveying process, and the offset or wrinkle of the automobile film is avoided, so that the automobile film can accurately reach the cutting position, and the precision and quality of the cutting are improved, and the cutting waste rate caused by the position deviation of the film is reduced.

[0013] Further, the output shaft of the hydraulic rod is provided with a positioning frame, the bottom end surface of the positioning frame is provided with a silica gel pad, and the positioning frame cooperates with the cutting platform to limit the automobile film body.

[0014] The beneficial effects of the above further scheme are:

[0015] When the automobile film body is conveyed to the cutting platform, the hydraulic rod drives the positioning frame to move downward, so that the positioning frame cooperates with the cutting platform to clamp the automobile film. The silica gel pad on the bottom end surface of the positioning frame has good flexibility and friction, which can avoid damaging the automobile film body during the clamping process and protect the surface quality of the film. On the other hand, the silica gel pad increases the friction between the automobile film, so that the automobile film can be fixed more firmly, and the movement of the automobile film during the cutting process is prevented, so that the size precision of the cutting and the flatness of the cutting edge are ensured.

[0016] Further, the top end surface of the first driving motor is provided with a guide block, the guide block is slidably sleeved on the guide rod, and the guide block is screwed on the lead screw.

[0017] The beneficial effects of the above further scheme are:

[0018] The second driving motor drives the screw rod to rotate, and the rotation of the screw rod drives the guide block to move linearly along the guide rod, because the guide block is installed on the screw rod through threads and is sleeved on the guide rod.

[0019] Further, the output shaft of the third driving motor is provided with a rotating shaft, the rotating shaft limits the automobile film body, and the rotating shaft is provided with bristles.

[0020] The beneficial effects of the above further scheme are:

[0021] During the unloading process of the automobile film, the third driving motor drives the rotating shaft to rotate. The rotating shaft plays a further limiting role on the automobile film body, ensuring the stable conveying of the automobile film during the unloading process. On the other hand, the bristles on the rotating shaft will brush and clean the surface of the automobile film as the rotating shaft rotates. The bristles can effectively remove the debris, dust and other impurities remaining on the surface of the automobile film during the cutting process, improve the surface cleanliness of the automobile film, ensure the appearance quality of the product, and reduce subsequent use problems caused by surface impurities.

[0022] Further, the gas collecting cover is embedded with a negative pressure pipe, and the negative pressure pipe is in gas communication with the gas collecting cover.

[0023] The beneficial effects of the above further scheme are:

[0024] When the bristles brush the surface of the automobile film to generate debris, a negative pressure environment is formed in the gas collecting cover through the negative pressure equipment (such as a vacuum pump) connected with the negative pressure pipe. This negative pressure environment will suck the debris brushed off into the gas collecting cover and discharge and collect through the negative pressure pipe. In this way, the debris generated during cutting and brushing can be cleaned in time and effectively, avoiding the debris from adhering to the surface of the automobile film again or flying in the working environment, maintaining the cleanliness of the working environment, and further improving the cleanliness and production quality of the automobile film.

[0025] The utility model provides a positioning mechanism for automobile film production and cutting.

[0026] The guide shaft limits the automobile film body, keeps the automobile film in a stable position and direction during conveying, avoids deviation or wrinkles, provides a basic guarantee for subsequent accurate cutting, helps to improve the cutting precision and quality, and reduces the cutting scrap rate caused by the position deviation of the film.

[0027] The silica gel pad at the bottom end face of the positioning frame has good flexibility and friction, which can avoid damaging the automobile film body during clamping, and protect the surface quality of the film; on the other hand, the silica gel pad increases the friction between the automobile film, which can more firmly fix the automobile film, prevent the automobile film from moving during cutting, and ensure the size accuracy of cutting and the flatness of the cutting edge.

[0028] The guide rod provides a guide for the movement of the guide block, ensures the straightness and stability of the movement track of the cutting blade, so that the automobile film body can be cut.

[0029] The bristles on the rotating shaft can brush and clean the surface of the automobile film with the rotation of the rotating shaft, which can effectively remove the debris, dust and other impurities remaining on the surface of the automobile film during cutting, improve the surface cleanliness of the automobile film, ensure the appearance quality of the product, and reduce the subsequent use problems caused by surface impurities.

[0030] The setting of the gas collecting cover and the negative pressure pipe can effectively clean the debris generated during cutting and brushing, avoid the debris from adhering to the surface of the automobile film or flying in the working environment again, maintain the cleanliness of the working environment, and further improve the cleanliness and production quality of the automobile film.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0042] Example 1

[0043] A positioning mechanism for cutting automotive film production includes a cutting machine body 1, a first drive motor 302 on the cutting machine body 1, a cutting blade 301 mounted on the output shaft of the first drive motor 302, an unwinding roller 101 mounted on the cutting machine body 1, and an automotive film body 102 connected to the unwinding roller 101.

[0044] The cutting machine body 1 is equipped with a mounting frame 2 and a cutting platform 3. A hydraulic rod 201 is installed on the mounting frame 2, and a bracket 307 is installed on the cutting platform 3. A guide rod 304 and a second drive motor 306 are installed on the bracket 307, and a lead screw 305 is installed on the output shaft of the second drive motor 306.

[0045] The rear end face of the cutting machine body 1 is equipped with a third drive motor 401 via a fixing frame 4, and a gas collection hood 403 is fixed on the fixing frame 4.

[0046] A guide shaft 104 is mounted on the front end of the cutting machine body 1 via a connecting frame 103. The guide shaft 104 limits the position of the automotive film body 102. The guide shaft 104 effectively limits the position of the automotive film body 102 as it is conveyed from the unwinding roller 101 to the cutting platform 3. This ensures the automotive film maintains a stable position and orientation during conveyance, preventing deviation or wrinkles. Consequently, the automotive film accurately reaches the cutting position, providing a foundation for precise subsequent cutting, improving cutting accuracy and quality, and reducing the scrap rate caused by film positional deviations.

[0047] A positioning frame 202 is mounted on the output shaft of the hydraulic rod 201. A silicone pad is fitted onto the bottom surface of the positioning frame 202, and the positioning frame 202 works with the cutting platform 3 to limit the position of the automotive film body 102. When the automotive film body 102 is transported onto the cutting platform 3, the hydraulic rod 201 drives the positioning frame 202 to move downwards, so that the positioning frame 202 cooperates with the cutting platform 3 to clamp the automotive film. The silicone pad on the bottom surface of the positioning frame 202 has good flexibility and friction. On the one hand, it can avoid damage to the automotive film body 102 during clamping, protecting the surface quality of the film; on the other hand, the silicone pad increases the friction between the film and the film, which can more firmly fix the film and prevent the film from moving during cutting, thereby ensuring the dimensional accuracy and the flatness of the cut edges.

[0048] A guide block 303 is mounted on the top surface of the first drive motor 302. The guide block 303 is slidably sleeved on the guide rod 304. The guide block 303 is threaded onto the lead screw 305. The second drive motor 306 drives the lead screw 305 to rotate. Since the guide block 303 is threaded onto the lead screw 305 and slidably sleeved on the guide rod 304, the rotation of the lead screw 305 will cause the guide block 303 to move linearly along the guide rod 304. The guide block 303 is connected to the first drive motor 302, which in turn drives the cutting blade 301 to perform linear cutting motion. The guide rod 304 provides guidance for the movement of the guide block 303, ensuring the straightness and stability of the movement trajectory of the cutting blade 301, thus enabling the cutting of the automotive film body 102.

[0049] Example 2

[0050] To clean the membrane during feeding by brushing and to collect and process the debris generated during cleaning, for example, such as Figures 1 to 5 As shown, this utility model also includes:

[0051] The output shaft of the third drive motor 401 is equipped with a rotating shaft 402, which limits the movement of the automotive film body 102. Brushes 405 are mounted on the rotating shaft 402. During the automotive film feeding process, the third drive motor 401 drives the rotating shaft 402 to rotate. The rotating shaft 402 serves two purposes: firstly, it further limits the movement of the automotive film body 102, ensuring smooth transport of the film during feeding; secondly, the brushes 405 on the rotating shaft 402 clean the surface of the automotive film as the shaft rotates. The brushes 405 effectively remove debris, dust, and other impurities remaining on the surface of the automotive film during the cutting process, improving the surface cleanliness of the film, ensuring the product's appearance quality, and reducing subsequent usage problems caused by surface impurities.

[0052] A negative pressure pipe 404 is embedded in the gas collection hood 403, and the negative pressure pipe 404 is in gas communication with the gas collection hood 403. When the brush 405 brushes the surface of the automotive film and generates debris, a negative pressure environment is created inside the gas collection hood 403 through a negative pressure device (such as a vacuum pump) connected to the negative pressure pipe 404. This negative pressure environment draws the brushed debris into the gas collection hood 403 and discharges it through the negative pressure pipe 404 for collection. This can effectively and promptly clean the debris generated during cutting and brushing, preventing debris from re-adhering to the surface of the automotive film or flying in the working environment, maintaining a clean working environment, and further improving the cleanliness and production quality of the automotive film.

[0053] Working principle:

[0054] Car film conveying: The car film body 102 on the unwinding reel 101 begins to be conveyed. During the conveying process, the front end face of the cutting machine body 1 limits the car film body 102 through the guide shaft 104 installed on the connecting frame 103, so that the car film maintains a stable position and direction during the conveying process, avoids deviation or wrinkles, and ensures that the car film can accurately reach the cutting position.

[0055] Automotive film positioning: After the automotive film body 102 is conveyed onto the cutting platform 3, the hydraulic rod 201 on the mounting bracket 2 drives the positioning bracket 202 mounted on its output shaft to move downward. The silicone pad on the bottom surface of the positioning bracket 202 cooperates with the cutting platform 3 to clamp the automotive film. The silicone pad not only avoids damage to the automotive film body 102 during clamping, but also fixes the automotive film more firmly by increasing friction, preventing the automotive film from moving during cutting.

[0056] Automotive film cutting: The second drive motor 306 starts, and the lead screw 305 mounted on its output shaft rotates. Since the guide block 303 mounted on the top surface of the first drive motor 302 is threaded onto the lead screw 305 and slidably sleeved on the guide rod 304, the rotation of the lead screw 305 drives the guide block 303 to move linearly along the guide rod 304. The guide block 303 drives the first drive motor 302 connected to it and the cutting blade 301 mounted on the output shaft of the first drive motor 302 to perform linear cutting motion, completing the cutting of the automotive film body 102.

[0057] Automotive film cutting and cleaning: During the automotive film cutting process, the third drive motor 401 on the fixing frame 4 is started, and the rotating shaft 402 on its output shaft rotates. The rotating shaft 402 serves two purposes: firstly, it further limits the automotive film body 102, ensuring smooth conveying of the automotive film during the cutting process; secondly, the brushes 405 installed on the rotating shaft 402 brush and clean the surface of the automotive film as the rotating shaft 402 rotates, removing debris, dust, and other impurities remaining on the surface of the automotive film during the cutting process.

[0058] Debris Collection: When the brush 405 brushes the surface of the automotive film and generates debris, a negative pressure device (such as a vacuum pump) connected to a negative pressure pipe 404 embedded in and in gas communication with the gas collection hood 403 creates a negative pressure environment within the gas collection hood 403. This negative pressure environment draws the brushed-off debris into the gas collection hood 403 and discharges it through the negative pressure pipe 404, maintaining a clean working environment and improving the cleanliness and production quality of the automotive film.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
