[0001] The utility model relates to the technical field of coating devices, and more specifically, to a coating device for film processing. Background Art

[0002] During the production and processing of films, it is necessary to coat glue on one side of the film. Manual gluing will result in an uneven glue layer and unstable glue consumption, thus affecting the film quality. Therefore, a coating device is generally used to coat glue on the film.

[0003] For example, a uniform gluing device disclosed in the patent with the publication number CN211134453U for the production of self-adhesive labels. Although the device is provided with scraping films oppositely on the glue tank, making the glue coated on the label tape more uniform and flat through double scraping operations, thereby improving the quality of the self-adhesive labels; however, in actual use, the glue tank is not provided with a stirring member. When the gluing device is not in use, the remaining glue in the glue tank will precipitate, resulting in uneven glue, and coating it on the product will affect the quality of the finished product. Therefore, it needs to be improved. Summary of the Utility Model

A main gear is sleeved on the extending end of the other of the two rotating shafts. The main gear meshes with the secondary gear.

[0009] Further, the clutch assembly includes a collar fixedly installed on the side wall of the secondary gear and through which the stirring shaft passes. The collar is provided with threaded holes, and the stirring shaft is provided with mounting holes corresponding to the threaded holes. A threaded rod that can extend into the mounting holes is arranged in the threaded holes. The threaded rod extends into the mounting holes to enable the secondary gear to drive the stirring shaft to rotate. An abutting ring is fixedly arranged outside the stirring shaft, and the abutting ring is used to rotatably mount the secondary gear on the stirring shaft.

[0024] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0025] The following will be further described in detail with reference to the attached Figures 1 - 5 This embodiment will be further described in detail.

[0026] Combined with Figures 1 - 5 As shown, a film processing and coating device in this embodiment includes a frame 100. Inside the frame 100, there are a main roller 150 and an auxiliary roller 140 for coating the film. Between the frames 100, there is a glue storage tank 120 for storing glue. A part of the main roller 150 extends into the glue storage tank 120. Inside the glue storage tank 120, there is a stirring member for stirring the glue. On the outer side wall of the frame 100, there is a driving assembly for driving the main roller 150 and the stirring member to rotate synchronously. The driving assembly is provided with a clutch assembly, and the clutch assembly is used to start and stop the stirring member.

[0027] In actual use of this embodiment, the frame 100 includes a bottom plate. At opposite ends of the bottom plate away from each other, there are side plates opposite to each other. The main roller 150 is rotatably arranged between the opposite side plates, and the auxiliary roller 140 is rotatably arranged between the side plates at a position above the main roller 150. There is a gap for the film to enter between the main roller 150 and the auxiliary roller 140. Through the setting of the driving assembly, the driving assembly can drive the main roller 150 to rotate, so that the main roller 150 can rotate in the glue storage tank 120, so that the surface of the main roller 150 can be covered with glue. At this time, the film is inserted into the gap, so that the main roller 150 can abut against the lower side surface of the film, and the auxiliary roller 140 can abut against the upper side surface of the film, so that the film can move between the main roller 150 and the auxiliary roller 140. At the same time, during the movement of the film, the main roller 150 can coat the glue on its surface on one side of the film, thus completing the glue coating on one side of the film;

[0028] In actual use, through the settings of the driving component and the stirring component, while the driving component can drive the main roller 150 to rotate, it can also drive the stirring component to rotate synchronously, so that the glue in the glue storage tank 120 can be stirred, preventing the glue in the glue storage tank 120 from precipitating and enabling it to be fully mixed, thereby preferably ensuring the quality of the film.

[0029] In this embodiment, the main roller 150 drives the stirring component to rotate synchronously, enabling the stirring component to work continuously during the process of applying glue along with the main roller 150. To avoid over-stirring the glue in the glue storage tank 120, which may cause air to enter the glue and generate bubbles, affecting the uniform application of the glue on the film by the main roller 150. After the glue in the glue storage tank 120 has been stirred for a period of time, through the setting of the clutch component, the clutch component can stop the rotation of the stirring component to prevent over-stirring of the glue by the stirring component.

[0030] In actual use, the cross-section of the glue storage tank 120 is U-shaped, and the lower side of the main roller 150 extends from the opening of the glue storage tank 120 into the glue storage tank 120. Wherein, mounting plates 130 are provided at both ends of the glue storage tank 120, and the mounting plates 130 are fixedly installed on the corresponding side plates by screws to realize the installation of the glue storage tank 120 on the frame 100.

[0031] Among them, as Figure 5 shown, a baffle 210 for preventing glue from splashing is further provided at the opening of the glue storage tank 120. The baffle 210 is provided with a notch 500 for a part of the main roller to extend into the glue storage tank 120. The side wall at the opening of the glue storage tank 120 extends outward to form a mounting part, and the baffle 210 is fixedly installed on the mounting part by screws to realize the installation of the baffle 210.

[0032] Among them, the baffle 210 is arranged along the length direction of the glue storage tank 120, and there is a small gap between the side walls of the notches 500 close to each other and the main roller 150. Thus, when the main roller 150 rotates, the splashing glue can splash onto the lower side of the baffle 210, avoiding the overflow of the glue.

[0033] Among them, reinforcing plates 160 are oppositely provided on the opposite outer side walls of the frame 100. The reinforcing plates 160 are used to enhance the connection strength between the side plates and the bottom plate and improve the strength of the frame 100.

[0034] Combined with Figures 2 - 3 shown, in this embodiment, the stirring component includes a stirring shaft 220 rotatably arranged in the glue storage tank 120. A plurality of stirring plates 230 are evenly arranged on the stirring shaft 220 along its circumference. One end of the stirring shaft 220 extends outside the frame 100; the driving component includes a sub-gear 310 arranged at the extending end of the stirring shaft 220, and the rotation of the sub-gear 310 is used to drive the stirring component to rotate.

[0035] In actual use of this embodiment, the rotation of the secondary gear 310 enables the secondary gear 310 to drive the stirring shaft 220 to drive the stirring plate 230 to rotate, thereby stirring the glue in the glue storage tank 120, so that the glue in the glue storage tank 120 is not likely to precipitate;

[0036] Among them, through the arrangement of a plurality of stirring plates 230, the glue in the glue storage tank 120 can be fully stirred.

[0037] Combined Figures 2 - 3 As shown, in this embodiment, rotating shafts 200 are provided at both ends of the main roller 150. The two rotating shafts 200 respectively pass through the corresponding side walls of the frame 100 and extend out. The driving assembly further includes a motor 110 provided on one side wall of the frame 100. The output shaft of the motor 110 is connected to one of the two rotating shafts 200 and is used to drive the rotating shaft 200 to rotate. A main gear 300 is sleeved on the other extending end of the two rotating shafts 200, and the main gear 300 meshes with the secondary gear 310.

[0038] In actual use of this embodiment, through the setting of the motor 110, the motor 110 can drive the corresponding rotating shaft 200 to rotate, so that the rotating shaft 200 can drive the main roller 150 to drive the rotating shaft 200 on the other side to rotate, and then the rotating shaft 200 on the other side can drive the main gear 300 to drive the secondary gear 310 to rotate, so that the secondary gear 310 can drive the stirring member to stir the glue in the glue storage tank 120;

[0039] In actual use, the main gear 300 is connected to the corresponding rotating shaft 200 by welding, thereby increasing the connection strength between the main gear 300 and the corresponding rotating shaft 200, so that the main gear 300 can preferably drive the secondary gear 310 to rotate;

[0040] Among them, both ends of the stirring shaft 220 and the rotating shaft 200 are rotatably installed on the corresponding side plates through bearing seats.

[0041] Combined Figure 4 As shown, in this embodiment, the clutch assembly includes a collar 420 fixedly installed on the side wall of the secondary gear 310 and through which the stirring shaft 220 passes. The collar 420 is provided with a threaded hole, and the stirring shaft 220 is provided with a mounting hole corresponding to the threaded hole. A threaded rod 400 that can extend into the mounting hole is threaded in the threaded hole. The threaded rod 400 extending into the mounting hole is used to enable the secondary gear 310 to drive the stirring shaft 220 to rotate. An abutting ring 430 is fixedly provided outside the stirring shaft 220, and the abutting ring 430 is used to enable the secondary gear 310 to be rotatably installed on the stirring shaft 220.

[0042] In actual use of this embodiment, the secondary gear 310 is rotatably sleeved on the protruding end of the stirring shaft 220. When it is necessary to stir the glue in the glue storage tank 120, rotate the stirring shaft 220 to align the mounting hole on the stirring shaft 220 with the threaded hole on the collar 420. At this time, thread the threaded rod 400 through the threaded hole and into the mounting hole, so that the collar 420 can be fixedly installed on the stirring shaft 220. Furthermore, the main gear 300 can drive the secondary gear 310 to drive the collar 420 to rotate, so that the collar 420 can drive the threaded rod 400 to drive the stirring shaft 220 to rotate, and the glue in the glue storage tank 120 is stirred;

[0043] In actual use, when it is necessary to stop stirring the glue in the glue storage tank 120, turn off the motor 110, rotate the threaded rod 400 out of the mounting hole, and then cancel the fixed connection between the secondary gear 310 and the stirring shaft 220. Start the motor 110, so that the main gear 300 drives the secondary gear 310 to rotate. At this time, the secondary gear 310 idles on the stirring shaft 220 and cannot drive the stirring shaft 220 to rotate synchronously, thus stopping the stirring of the glue in the glue storage tank 120;

[0044] Among them, in order to facilitate the alignment of the mounting hole on the stirring shaft 220 with the threaded hole on the collar 420, a U-shaped handle 440 is provided at the end of the protruding end of the stirring shaft 220. The horizontal plane where the handle 440 is located is arranged in the same direction as the mounting hole. Through the setting of the handle 440, it is convenient for the operator to rotate the stirring shaft 220. When the handle 440 is in the same direction as the threaded rod 400, the alignment of the mounting hole and the threaded hole can be achieved;

[0045] Among them, fixing columns 410 are provided on the outer side wall of the collar 420, and the threaded holes extend axially along the fixing columns 410 into the fixing columns 410. Through the setting of the fixing columns 410, when the contact area between the threaded rod 400 and the threaded hole increases, the contact area between the threaded rod 400 and the collar 420 increases, so that the connection between the collar 420 and the stirring shaft 220 is more firm;

[0046] Among them, the abutting ring 430 is fixedly sleeved on the stirring shaft 220 by welding, so that the stirring shaft 220 can drive the abutting ring 430 to rotate synchronously;

[0047] Among them, through the setting of the abutting ring 430, one side wall of the collar 420 abuts against the abutting ring 430, and one side wall of the secondary gear 310 abuts against the corresponding side plate, so that the secondary gear 310 cannot move along the stirring shaft 220, that is, the rotational installation of the secondary gear 310 is realized.

[0048] Working principle: When it is necessary to coat the film with glue, start the motor 110, so that the motor 110 drives the rotating shaft 200 to drive the main roller 150 to rotate, making its surface adhere to the glue. Insert the film into the gap between the main roller 150 and the auxiliary roller 140, so that the main roller 150 drives the auxiliary roller 140 to rotate through the film, making the film move and enabling the main roller 150 to coat one side of the film with glue. At this time, the main roller 150 drives the rotating shaft 200 on the other side to rotate and drives the main gear 300 to rotate, and then the main gear 300 drives the auxiliary gear 310 to drive the stirring member to rotate, so that the glue in the glue storage tank 120 is stirred. When it is necessary to stop stirring the glue in the glue storage tank 120, remove the threaded rod 400 on the collar 420. At this time, the auxiliary gear 310 cannot drive the stirring member to rotate, thus stopping the stirring of the glue in the glue storage tank 120.

[0049] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
