Description

Technical Field

[0001] The utility model relates to a point-sticking mechanism for the tail film of a wrapping machine, in particular to a point-sticking mechanism for the tail film of a wrapping machine which can stick and fix the tail section of the wrapping film. Background Art

[0002] Currently, after large cargo is boxed, it is typically wrapped with film to protect the exterior from dirt, water, and dust. However, in today's technologically advanced world, and driven by the need to save labor and increase packaging speed, automated film wrapping has become increasingly common. This process allows for efficient and rapid film application around the exterior of boxes.

[0003] The inventor has developed a variety of film wrapping machine technologies in the industry, such as early wrapping machine patents with announcement numbers TWM268285U, TWM392147U, TWM398517U, TWM488462U, and TWM571350U, as well as recently approved patents TWM633372U for a "corner plate storage mechanism for a wrapping machine," TWM633373U for a "corner plate fixing mechanism for a wrapping machine," and TWM633375U for a "corner plate guiding mechanism for a wrapping machine." These film wrapping machines can achieve the desired effect of axially and radially wrapping the objects to be wrapped with film.

[0004] However, in the spirit of continuous improvement and the concept of continuous progress in the industry, the inventors conducted research and development on factors such as the smoothness and convenience of the wrapping machine under all operating conditions. During the research process, they found that the tail section of the film after wrapping the film on the object is roughly pressed flat against the surface of the wrapped object by a brush flattening machine. The adhesion is achieved through the principle of electrostatic friction. However, during the transportation of the items, the tail section of the film cannot be effectively controlled to prevent it from falling off or being opened. This defect can easily cause the film to fall off or the films of two items to stick to each other.

[0005] Therefore, the inventor, based on many years of rich design, development and actual production experience in the related industry, specially provides a point-sticking mechanism for the tail film of the wrapping machine to achieve the purpose of better practical value. Utility Model Content

However, the specific embodiments of the present invention described herein are for the purpose of explaining the present invention only and should not be construed as limiting the present invention in any way. Based on the teachings of the present invention, skilled artisans can conceive of any possible variations based on the present invention, which should be considered to fall within the scope of the present invention.

[0056] Unless otherwise specified, the directions of up, down, left, and right mentioned in this document are based on the directions shown in this utility model. Figure 1 The up, down, left and right directions in the figure shall prevail and are explained here.

[0057] In order to make the technical content, purpose and effect achieved by the present invention more complete and clear, it is described in detail below. Please refer to the drawings and figure numbers in the specification:

[0058] First, see Figures 1 to 3 The figure shows the three-dimensional appearance, side view, and top view of the wrapping machine's tail film taping mechanism of the present invention. The wrapping machine primarily allows items to be wrapped with film, with film A being wrapped around the items. A taping mechanism B is provided on one side of the wrapping machine. The taping mechanism B adheres the tail section of film A to the wrapped items by applying tape D to the tail section. The taping mechanism B includes:

[0059] A machine 1 is provided with a slide rail assembly 11 and a first power source 12 , wherein the first power source 12 has an output shaft 121 ;

[0060] a movable base 2, correspondingly arranged on the slide rail assembly 11 and connected to the end of the output shaft 121 of the first power source 12;

[0061] At least one tape application module 3 is mounted on the movable base 2 and includes a frame 31. A tape placement pulley 32 for placing the tape D is provided on the frame 31, and a second power source 33 connected to a sensor 332 (which may be a reed switch) is installed. The end of the output shaft 331 of the second power source 33 is connected to a first swing arm 34 pivotally mounted on the frame 31, and a belt adjustment pulley assembly 35 is pivotally mounted at the pivot. A contact pressure wheel 341 is provided at the front end of the first swing arm 34. , so that the tape D passes through the tape adjusting wheel group 35 and is clamped between the tape adjusting wheel group 35 and the contact pressure wheel 341, and then a second swing arm 36 is pivotally provided on the frame 31 and is located on one side of the first swing arm 34, one end of the second swing arm 36 is embedded in a movable groove 311 set on the frame 31, and the other end is provided with a cutter 361 for cutting the tape D, and an elastic member 37 is hooked on the second swing arm 36, and one end of the elastic member 37 is hooked on the frame 31.

[0062] When the tape D is assembled, it is positioned on the placing pulley 32 and the tape D is pulled out and passed between the tape adjusting pulley assembly 35 and the contact and pressure roller 341. The tape adjusting pulley assembly 35 further includes a base 351. An intermediate wheel 352 is provided at one end of the base 351 and pivoted at the pivot point between the first swing arm 34 and the frame 31. A pressure roller 353 is provided at the other end of the base 351. The tape D passes through the intermediate wheel 352 and is clamped between the pressure roller 353 and the contact and pressure roller 341. In addition, an auxiliary wheel assembly 38 is provided between the placing pulley 32 and the tape adjusting pulley assembly 35 to assist in guiding the tape D.

[0063] See also Figures 1 to 7 As shown, when it is actually implemented, the point-sticking mechanism B of the present invention is set on the output path after the article is wrapped by the film A, and a smoothing brush 4 (such as Figure 2 As shown), when the tail section of the film A passes through the smoothing brush 4, the tail section of the film A can be adhered to the object C: then, when the object C is transported close to the dot-sticking mechanism B, the first power source 12 is started, causing the output shaft 121 to extend and drive the movable base 2 to move. At this time, the tape dot-sticking module 3 assembled on the movable base 2 can be stably approached to the object C through the guidance of the slide rail group 11.

[0064] Continuing from the above, when the tape applying module 3 at the front end of the movable base 2 moves forward and contacts the tail section of the adhesive film A on the object C, it first touches the touch-pressure wheel 341 on the first swing arm 34. When in contact, the tape clamped between the pressure-regulating wheel 353 and the touch-pressure wheel 341 is adhered to the tail section of the adhesive film A. The tape applying module 3 continues to move forward. Through the displacement of the touch-pressure wheel 341, the first swing arm 34 rotates and stretches the output shaft 331 of the second power source 33, thereby triggering (starting) a sensor 332 to start the tape application timer (e.g., 1 to 2 seconds, at which time the first power source 12 stops). During the timing process, the object C continues to be transported backward so that its tape D can adhere to a certain length. When the time is up, the second power source 33 is started to extend the output shaft again. The first swing arm 34 is driven to move the pressure wheel 341 toward the cutter 361 of the second swing arm 36, thereby pushing the cutter 361 to move. Since one end of the second swing arm 36 is limited by the movable groove 311 on the frame 31, the second swing arm 36 allows the cutter 361 to cut the tape D between the object and the pressure wheel 341. In this way, the tape D is glued to the tail section of the film A.

[0065] After the tape D is cut, the article C continues to be conveyed backward. At this time, at least one flattening roller 39 is provided on the frame 31. This flattening roller 39 smoothes the cut tape D against the surface of the article C, ensuring a more secure adhesion. Finally, after the application is complete, the output shaft 331 of the second power source 33 retracts, driving the first swing arm 34 to reset the contact roller 341. The second swing arm 36, through the elastic force of the elastic member 37, resets the cutter 361.

[0066] The aforementioned embodiments or drawings do not limit the structural form of the present invention. Any appropriate changes or modifications made by technicians in the relevant technical field should be deemed to be within the scope of protection of the claims of the present invention.

[0067] In summary, the embodiments of the present utility model can indeed achieve the expected use effect, and the specific structure disclosed therein has not only never been seen in similar products, but has also not been disclosed before the application. It fully complies with the provisions and requirements of the Patent Law. Now, an application for a utility model patent is filed in accordance with the law.
