[0024] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0025] See also Figures 1 to 3 A packaging device for bandage production includes a frame 3 and two hot wheel assemblies 4 symmetrically arranged on the left and right. The hot wheel assembly 4 includes a support shaft 41, a rotating bracket 42, and hot wheels 43 rotatably connected to both ends of the rotating bracket 42. The support shaft 41 is vertically installed on the upper side of the bracket. The middle part of the rotating bracket 42 is rotatably connected to the upper end of the support shaft 41. The hot wheel 43 at the front end or the rear end of the rotating bracket 42 clamps the film and adheres the film to wrap the upper side of the bandage. The hot wheel 43 at the other end of the rotating bracket 42 is detached from the film.

[0026] The packaging device further comprises a rotating mechanism 5, which is used for synchronously rotating the rotating brackets 42 of the two heat wheel assemblies 4 in opposite directions to switch the heat wheel 43 that clamps the film.

[0027] Through the above arrangement, the hot wheels 43 at the front and rear ends of the rotating bracket 42 can both seal the edge of the film. When cleaning the hot wheel 43, switch to another hot wheel 43 to continue sealing the edge of the film. There is no need to stop the packaging equipment and the packaging efficiency is not affected.

[0028] In the present application, the packaging equipment further includes a film discharging mechanism, a film flanging mechanism, and a feeding mechanism. The frame 3, the film discharging mechanism, the film flanging mechanism, the feeding mechanism, and the hot wheel 43 can refer to the existing packaging equipment; Figure 1 The front, rear, left, and right sides of the packaging device are indicated in the figure. The rotating bracket 42 basically extends along the front and rear directions of the packaging device. In specific use, the front end of the rotating bracket 42 is tilted inward or outward to Figure 1For example, the front end of the rotating bracket 42 is inclined inward, and the film extends forward on the upper side of the frame 3. The hot wheel 43 at the front end of the rotating bracket 42 and the hot wheel 43 at the front end of another rotating bracket 42 are close to clamp the film, and the hot wheel 43 rotates under the drive of the motor, sealing the edge of the film while driving the film to move forward. At this time, the hot wheel 43 at the rear end of the rotating bracket 42 is disengaged from the film and does not work; when impurities on the hot wheel 43 at the front end of the rotating bracket 42 need to be cleaned, the rotating mechanism 5 drives the rotating bracket 42 to rotate around the axis of the support shaft 41, and the rear ends of the rotating brackets 42 on the left and right sides rotate inward synchronously, and the hot wheel 43 at the rear end of the rotating bracket 42 clamps the film, and the hot wheel 43 continues to seal the edge of the film after rotating, while the hot wheel 43 at the front end of the rotating bracket 42 is disengaged from the film, which is convenient for the staff to clean impurities on the hot wheel 43.

[0029] As an implementation method, the hot wheel assembly 4 further includes: a connecting plate 44 and a fixing key 45; the connecting plate 44 is fixedly connected to the inner side of the middle part of the rotating bracket 42; the fixing key 45 is fixedly connected to the upper side of the connecting plate 44;

[0031] Through the above arrangement, the rotating bracket 42 is driven to rotate by the extension and retraction of the electric push rod 52 .

[0032] In the present application, the fixed key 45 is cylindrical, and the width of the long hole 511 is equal to the outer diameter of the fixed key 45, so as to prevent the fixed key 45 from shaking in the long hole 511, thereby preventing the rotating bracket 42 from shaking; in the present application, the electric push rod 52 is extended and retracted to drive the push plate 51 to move forward or backward, and the push plate 51 rotates the rotating bracket 42 through the fixed key 45. The rotation amplitude of the rotating bracket 42 can be controlled by the extension and retraction amount of the electric push rod 52, so that the rotating bracket 42 can be rotated to the right position.

[0033] As an implementation method, the rotating mechanism 5 also includes: a mounting frame 53; the mounting frame 53 is installed on the upper side of the frame 3, and a through hole 531 is provided on the mounting frame 53 for the bandage and the film to pass through, and the electric push rod 52 is installed on the upper side of the mounting frame 53.

[0034] As an implementation method, the packaging equipment also includes a scraper 62 assembly 6, which is installed on the upper side of the frame 3 and located on the outer side of the hot wheel 43.

[0035] Through the above arrangement, after the heat wheel 43 is separated from the film, it automatically contacts the scraper 62 assembly 6, so that impurities on the heat wheel 43 are easily cleaned.

[0036] In the present application, when the front end heat wheel 43 seals the edge of the film, the rear end heat wheel 43 contacts the scraper 62 assembly 6, and when there are impurities on the rear end heat wheel 43, the motor drives the rear end heat wheel 43 to rotate, and the scraper 62 assembly 6 scrapes off the impurities on the surface of the heat wheel 43. Similarly, when the rear end heat wheel 43 seals the edge of the film, the front end heat wheel 43 contacts the scraper 62 assembly 6, and when the front end heat wheel 43 rotates, the scraper 62 assembly 6 scrapes off the impurities on the surface of the front end heat wheel 43. No manual cleaning is required, saving time and effort.

[0037] As an implementation method, the scraper 62 assembly 6 includes: a mounting sleeve 61, a scraper 62, and a spring 63; the mounting sleeve 61 is fixedly connected to the upper side of the frame 3, and the sleeve opening of the mounting sleeve 61 faces the hot wheel 43; one end of the scraper 62 is slidably connected in the mounting sleeve 61, and the other end of the scraper 62 faces the hot wheel 43 and can contact the hot wheel 43; the spring 63 is arranged in the mounting sleeve 61, one end of the spring 63 is fixedly connected to the bottom of the mounting sleeve 61, and the other end of the spring 63 is fixedly connected to the scraper 62.
