Description

Technical Field

[0001] The utility model relates to a heat-sealing mechanism for the tail film of a wrapping machine, especially a heat-sealing mechanism for the tail film of a wrapping machine that can heat-seal and fix the tail section of the plastic film used for wrapping. Background Art

[0002] At present, after general large-sized goods are packed in boxes, a plastic film wrapping process is carried out around the outer periphery of the box after packing to achieve the purpose of anti-fouling, waterproofing, and dust-proofing on its surface. However, in today's society with the progress of technology, considering the need to save labor and the requirement of rapid packaging, the plastic film wrapping process has long been carried out by automated machines, and the automated machines can effectively and rapidly wrap the plastic film around the outer periphery of the box.

[0003] The inventor has developed a variety of plastic film wrapping machine technologies in the industry, such as wrapping machine patents with early publication numbers TWM268285U, TWM392147U, TWM398517U, TWM488462U, TWM571350U, etc., and the recently approved patent with publication number TWM633372U for "corner plate storage mechanism of a wrapping machine", the patent with publication number TWM633373U for "corner plate fixing mechanism of a wrapping machine", and the patent with publication number TWM633375U for "corner plate feeding mechanism of a wrapping machine"; through the above-mentioned plastic film wrapping machines, the expected effects of axially and radially wrapping the object to be wrapped with the plastic film can be achieved.

[0004] However, in line with the spirit of striving for perfection and the concept that the industry needs to continuously progress, the inventor conducts research and development on factors such as the smoothness and convenience of the wrapping machine under any operating conditions. During the research process, it is found that the tail section of the plastic film after wrapping the object is roughly flattened by a brushing machine and pressed flat against the surface of the object to achieve flatness through the principle of electrostatic friction, but the tail film cannot be effectively controlled from falling off or being lifted during the transportation of the object, and such deficiencies are likely to cause problems such as the plastic film falling off or the plastic films of two objects sticking to each other.

[0005] Therefore, the inventor, based on rich design and development and actual production experience in this related industry for many years, hereby provides a heat-sealing mechanism for the tail film of a wrapping machine to achieve a more practical value purpose. Summary of the Utility Model

[0050] Combined with the description of the accompanying drawings and the specific implementation manners of the present utility model, the details of the present utility model can be more clearly understood. However, the specific implementation manners of the present utility model described herein are only for the purpose of explaining the present utility model and cannot be understood in any way as a limitation of the present utility model. Under the teaching of the present utility model, those skilled in the art can conceive any possible variations based on the present utility model, and these should all be regarded as belonging to the scope of the present utility model.

[0051] Unless otherwise defined, the up, down, left, right and other directions mentioned herein are based on the up, down, left, right and other directions shown in the present utility model Figure 1 and are hereby explained together.

[0052] In order to more completely and clearly disclose the technical content, purpose and achieved effects of the present utility model, the following will be described in detail, and please also refer to the accompanying drawings of the specification and the reference numerals:

[0053] First, please refer to Figures 1 to 3As shown in the three-dimensional appearance and side cross-sectional schematic diagram of the heat-sealing mechanism of the tail film of the wrapping machine of the present utility model, it is mainly to wrap an item with a plastic film through a wrapping machine, wind the plastic film A around the outer periphery of the item, and a heat-sealing mechanism B is provided on one side of the wrapping machine. The heat-sealing mechanism B is used to heat-seal the tail section of the plastic film A so that the tail section of the plastic film A adheres to the wrapped item. The heat-sealing mechanism B includes:

[0054] A machine platform 1 is provided with a substrate 11, and a power source 12 is assembled on the substrate 11. The power source 12 has an output shaft 121;

[0055] A movable seat 2 is correspondingly assembled at the end of the output shaft 121 of the power source 12;

[0056] At least one heat-sealing module 3 includes a heating element 31, and the heating element 31 can correspondingly contact the tail section of the plastic film A;

[0057] At least one adjustment group 4 includes a fixing seat 41 for assembling the heat-sealing module 3. Support rods 42 are respectively assembled on both sides of the fixing seat 41, and elastic members 43 are sleeved on the support rods 42. One end of the support rod 42 is correspondingly inserted and assembled on the movable seat 2. The adjustment group 4 is used to adjust the acting force (strength) between the heating element 31 and the tail section of the plastic film A in contact.

[0058] Please refer to Figures 1 to 7 As shown, when actually operating and implementing, the heat-sealing mechanism B of the present utility model is arranged on the output path after the item is wrapped with the plastic film A. A smoothing brush 6 for smoothing the tail section of the plastic film A is provided on the path (as Figure 5 shown). When the tail section of the plastic film A passes over the smoothing brush 6, the tail section of the plastic film A can be made to adhere to the item C. Then, when the item C is conveyed close to the heat-sealing mechanism B, the power source 12 is started, and the output shaft 121 extends to drive the movable seat 2 to approach the item C. Further, at least one limiting support tube 111 is provided on the extension of the substrate 11 during the extension of the output shaft 121. A guide rod 21 is provided on the movable seat 2 corresponding to the limiting support tube 111. The guide rod 21 is embedded in the limiting support tube 111, so that when the output shaft 121 extends to drive the movable seat 2 to move forward, the stability of the forward stroke can be assisted by the sliding displacement of the guide rod 21 in the limiting support tube 111.

[0059] Continuing the above, when the heat-sealing module 3 at the front end of the movable seat 2 moves forward and contacts the tail section of the plastic film A on the item C, the temperature generated by the heating element 31 on the heat-sealing module 3 can correspondingly contact the tail section of the plastic film A, so that the tail section of the plastic film A adheres to the wrapped item.

[0060] However, the structure of the hot stamping module 3 has various change modes. Here, a feasible implementation mode is proposed. The hot stamping module 3 further includes a constant temperature heating sheet 33 installed on a bottom plate 32. The constant temperature heating sheet 33 is arranged on the back of the electric heating sheet 31, and the bottom plate 32 is correspondingly set on the fixed seat 41. In this way, through constant temperature setting, the temperature of the electric heating sheet 31 for hot stamping the adhesive film A will not continuously rise to thermally melt the adhesive film A.

[0061] In addition, when the electric heating sheet 31 on the hot stamping module 3 contacts the tail section of the adhesive film A on the article C, the force of the contact between the electric heating sheet 31 and the tail section of the adhesive film A can be adjusted through the support rod 42 and the elastic member 43 in the adjustment group 4. When the electric heating sheet 31 advances and contacts the tail section of the adhesive film A on the surface, the elastic member 43 can be compressed to maintain an appropriate contact pressure, so that the heat of the electric heating sheet 31 is transferred to the tail section of the adhesive film A on the surface, achieving accurate contact and temperature transfer to melt and bond the tail section of the adhesive film A to the surface, without the problem of deeply thermally wrapping the adhesive film A of the article C, and achieving the effect of perfect and flat hot stamping of the tail section of the adhesive film A for finishing and bonding.

[0062] Finally, on the machine table 1 of the hot stamping mechanism B, there is an outer housing 5. The outer housing 5 covers the outside of the movable seat 2, the hot stamping module 3 and the adjustment group 4. One end of the outer housing 5 has an opening 51 through which the hot stamping module 3 can extend out, and the other end is provided with a through hole 52 for the power source 12 to pass through and a through hole 53 for the limit support tube 111 to pass through and move displaceably.

[0063] The foregoing embodiments or drawings do not limit the structural mode of the present invention. Any appropriate changes or modifications by those skilled in the art shall be regarded as not departing from the protection scope of the claims of the present invention.

[0064] In summary, the embodiments of the present invention can indeed achieve the expected use effects. Moreover, the specific structure proposed by it has not been seen in similar products and has not been made public before the application. It has fully complied with the provisions and requirements of the Patent Law. Now, an application for a utility model is filed according to law.
