[0001] The utility model relates to the technical field of automated production, in particular to a novel online film-tearing mechanism. Background Art

[0002] In the automated production process of products, the automatic assembly line is an important part. Parts or components that have been produced in other workshops are usually covered with a layer of protective film. Therefore, during the operation of the automatic assembly line, the protective film needs to be torn off to facilitate the overall assembly of the product.

[0003] The existing Chinese patent with announcement number CN114905835A discloses a film tearing mechanism including an adsorption head, a clamping head, a clamping cylinder, an adsorption lifting cylinder, a flip film tearing cylinder and a horizontal moving cylinder; the horizontal moving cylinder and the flip film tearing cylinder drive the adsorption head, the clamping head, the clamping cylinder and the adsorption lifting cylinder to translate and rotate; the adsorption head is detachably connected to the piston of the adsorption lifting cylinder, and the clamping head is fixedly connected to the piston of the clamping cylinder. The adsorption part of the adsorption head is contoured and rotates to a preset second angle driven by the adsorption lifting cylinder to be the same as the bevel angle of the clamping part of the clamping head.

[0004] The above-mentioned film tearing mechanism adopts an adsorption head to absorb the protective film, and the adsorption lifting cylinder pushes the adsorption head to swing angle, and the horizontal moving cylinder cooperates with the flip film tearing cylinder and the clamping cylinder to drive the clamping head close to the adsorption head to clamp the protective film and complete the film tearing action. However, this device does not solve the problem of collecting the protective film after film tearing. The protective film still needs to be transferred and collected by an additional collection device. Not only the film tearing efficiency is affected, but also the film tearing actions are numerous, resulting in a complex structure and prone to failure. Utility Model Content

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a novel online film tearing mechanism, comprising a mounting plate, an L-shaped supporting plate is fixedly mounted on one side of the mounting plate, a motor is fixedly mounted on the outer side of the supporting plate, the output end of the motor movably penetrates the side wall of the supporting plate, the output end of the motor is fixedly connected with a winding roller, the winding roller movably penetrates the mounting plate, a reeling roller is fixedly mounted on a side wall of the mounting plate away from the motor, the reeling roller is sleeved with an adhesive tape, two auxiliary rollers are rotatably mounted on the bottom of one side of the mounting plate close to the reeling roller, an auxiliary mechanism is arranged on the mounting plate, and the motor is transmission-connected to the auxiliary mechanism.

[0008] According to the above-mentioned novel online film tearing mechanism, the auxiliary mechanism includes a rotating shaft rotatably installed on the outer wall of the mounting plate close to the motor side, the winding roller is transmission-connected to the rotating shaft, a missing gear is fixedly installed on the rotating shaft, a rack is slidably installed on the outer wall of the mounting plate close to the motor side, the missing gear is meshed with or disengaged from the rack, a connecting block is fixedly installed on the side of the rack close to the mounting plate, the connecting block movably passes through the mounting plate and is fixedly connected to a pressure plate.

[0009] According to the above-mentioned new type of online film tearing mechanism, a sliding groove is provided on the mounting plate and is slidingly connected to the connecting block, a support shaft is fixedly installed on the inner bottom wall of the sliding groove, the connecting block is sleeved on the outside of the support shaft and is slidingly connected to the support shaft, a spring is sleeved on the outside of the bottom of the support shaft, the bottom end of the spring is fixedly connected to the inner bottom wall of the support shaft, and the top end of the spring is fixedly connected to the bottom wall of the connecting block.

[0010] According to the novel online film tearing mechanism, the sizes of the rack and the pressure plate are larger than the inner diameter of the slide groove, and the sides of the rack and the pressure plate close to the mounting plate are in contact with the mounting plate.

[0011] According to the above-mentioned novel online film tearing mechanism, a plurality of pressure columns are fixedly installed on the bottom side of the pressure plate.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. The motor drives the winding roller to rotate to wind the tape. When the tape is wound by the auxiliary roller, the pressure plate and the pressure column press it on the protective film of the product, so that the tape and the protective film are adhered to each other. The tension generated by the winding roller on the tape winding causes the tape and the protective film to be wound on the winding roller synchronously, so that the protective film is wound and wound on the winding roller while being torn off by the tape. As the winding roller rotates, the film tearing is also carried out continuously. The operation is simple and the structure is compact, and there is no need to set up a protective film collection device separately.

[0015] 2. The transmission between the winding roller and the rotating shaft makes the gear and the winding roller rotate synchronously. Under the action of gravity and the spring, the rack repeats the process of moving up and down, so that the pressure plate and the pressure column can firmly press the tape on the protective film of the product to ensure that the tape and the protective film are adhered to each other, and the auxiliary tape tears off the protective film when being rolled up;

[0016] To sum up, the utility model uses a motor, a winding roller and a rotating shaft to enable the winding roller to rewind the tape while also tearing off and rewinding the protective film stuck to the tape. As the winding roller rotates, the film tearing is also continuously carried out. The operation is simple and the structure is compact, and there is no need to set up a separate protective film collection device. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Specifically, the auxiliary mechanism includes a rotating shaft 7 rotatably installed on the outer wall of the mounting plate 1 on one side close to the motor 3, the winding roller 4 is transmission-connected with the rotating shaft 7, a missing gear 8 is fixedly installed on the rotating shaft 7, a rack 9 is slidingly installed on the outer wall of the mounting plate 1 on one side close to the motor 3, the missing gear 8 is meshed with or separated from the rack 9, a connecting block 14 is fixedly installed on the side of the rack 9 close to the mounting plate 1, the connecting block 14 movably penetrates the mounting plate 1 and is fixedly connected with a pressure plate 10, the pressure plate 10 is placed above the tape 6 between the two auxiliary rollers 5, and a plurality of pressure columns 11 are fixedly installed on the bottom side of the pressure plate 10; when the motor 3 drives the winding roller 4 to rotate, the winding roller 4 drives the rotating shaft 7 and the missing gear 8 fixedly connected to the rotating shaft 7 to rotate through the transmission connection, and the missing gear 8 drives the gear 8 to rotate through the meshing transmission The rack 9, connecting block 14 and pressure plate 10 move upward. After the missing gear 8 is separated from the rack 9, the rack 9, pressure plate 10 and connecting block 14 fall downward under the action of gravity, so that the pressure column 11 on the bottom side of the pressure plate 10 presses the tape 6 on the protective film on the surface of the product. The tape 6 contacts the protective film, and under the action of the pressure column 11, the force area between the tape 6 and the protective film is reduced, and the force is more concentrated, ensuring that the tape 6 and the protective film are adhered to each other. The sizes of the rack 9 and the pressure plate 10 are larger than the inner diameter of the slide groove 12, and the side of the two close to the mounting plate 1 is in contact with the mounting plate 1. The size of the rack 9 and the pressure plate 10 is larger than the size of the slide groove 12, preventing the rack 9 or the pressure plate 10 from passing through the slide groove 12 and affecting its normal operation.

[0027] Furthermore, a slide groove 12 is provided on the mounting plate 1 and is slidably connected to a connecting block 14.

The bottom end of the spring 15 is fixedly connected to the inner bottom wall of the supporting shaft 13, and the top end of the spring 15 is fixedly connected to the bottom wall of the connecting block 14. The elastic force of the spring 15 pulls the connecting block 14 toward the inner bottom wall of the supporting shaft 13. When When the rack 9 moves upward under the action of the missing gear 8, the spring 15 is stretched. After the missing gear 8 is separated from the rack 9, the elastic force of the spring 15 enables the rack 9, the connecting block 14 and the pressure plate 10 to move downward at a faster speed, so that the pressure column 11 can press the tape 6 more firmly against the surface of the protective film on the product. When the rack 9 drives the connecting block 14 to move upward, the connecting block 14 slides on the support shaft 13, and the support shaft 13 prevents the spring 15 from being entangled during the stretching and rebounding process.

[0028] The working principle of the utility model is as follows:

[0029] When it is necessary to tear the film of the product, the device is installed on one side of the product conveying line through the mounting plate 1, and the height of the mounting plate 1 is adjusted. Then, the starting end of the tape 6 is wound around the winding roller 4 after passing through the auxiliary roller 5 and fixedly connected to the winding roller 4. The motor 3 is started to allow the output end of the motor 3 to drive the winding roller 4 to rotate. When the winding roller 4 rotates, the tape 6 is wound. At the same time, the motor 3 drives the rotating shaft 7 and the missing gear 8 to rotate through the winding roller 4. The missing gear 8 drives the rack 9, the connecting block 14 and the pressure plate 10 to move upward through the meshing transmission. At this time, the connecting block 14 drives The spring 15 is stretched, and after the missing gear 8 is separated from the rack 9, the elastic force of the spring 15 enables the rack 9, the connecting block 14 and the pressure plate 10 to move downward at a faster speed, so that the tape 6 is pressed on the protective film on the surface of the product, and the tension generated by the winding roller 4 on the winding of the tape 6 causes the tape 6 and the protective film stuck on the tape 6 to be synchronously wound up, so that the protective film is torn off by the tape 6 and is wound and wound on the winding roller 4 at the same time, and the film tearing is continuously carried out as the winding roller 4 rotates. The operation is simple and the structure is compact, and there is no need to set up a protective film collecting device separately.
