TECHNICAL FIELD

[0001] The utility model relates to a sealing device technical field especially relates to a tubular workpiece sealing sticker mechanism. BACKGROUND

[0002] In the current heating non-combustible cartridge production, especially for the sealing process of the cartridge end face, due to the influence of paper tube material production process and other factors, there are differences in the flatness of the paper tube end face, and there is no shaping process in the previous sealing process, which cannot make the tubular workpiece end face completely adhere to the high-transparency paper and the drying time is relatively long, which leads to the opening phenomenon of the sealing, thereby seriously affecting the production quality and production efficiency.

[0003] Therefore, we propose a tubular workpiece sealing sticker mechanism to solve the above problems. UTILITY MODEL CONTENT

[0015] As a further optimization scheme, a circular induction sheet is arranged at the shaft center of one end of the first tensioning roller, and a plurality of induction grooves are arranged on the circular induction sheet in the circumferential direction and are used to control the first driving part to drive the high-transparency paper to move equidistantly.

[0016] As a further optimization scheme, the paper pasting mechanism comprises a paper pasting frame, a paper cutting part, a fixed plate, an outer die, a moving plate, an inner die, a vacuum generator, a second driving part and a positioning part, and the positioning part comprises a positioning fixed plate, a positioning moving plate and a third driving part.

[0017] The paper pasting frame is provided with the paper cutting part, which is used to cut the high-transparency paper and directly paste the cut high-transparency paper on the end face of the tubular workpiece, and the positioning part for positioning the tubular workpiece before pasting is arranged below the paper cutting part.

[0018] The fixed plate is provided with a plurality of outer dies corresponding to the tubular workpieces in the tubular workpiece jig one by one, the outer die is a tubular structure, the moving plate is provided with a plurality of inner dies corresponding to the outer dies one by one, and the inner die is also a tubular structure and is connected with the vacuum generator through a quick connector at the upper end face.

[0019] The second driving part is used to drive the inner die to move downward to cut the high-transparency paper through the outer die, and the inner die continues to move downward until the high-transparency paper is attached to the end face of the tubular workpiece.

[0020] The positioning fixed plate and the positioning moving plate are arranged on the two sides of the tubular workpiece respectively, and the third driving part is used to drive the positioning moving plate to move in the direction of approaching the positioning fixed plate, so that the tubular workpiece is clamped between the positioning fixed plate and the positioning moving plate.

[0021] As a further optimization scheme, the second driving part drives the inner die to move downward to cut the high-transparency paper through the outer die, the vacuum generator causes the cut high-transparency paper to be adsorbed to the lower end of the inner die, and the inner die continues to move downward until the high-transparency paper is attached to the end face of the tubular workpiece.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects:

[0026] The high-permeability paper is cut and vacuum-adsorbed onto the lower end of the inner die, directly adhering to the end face of the tubular workpiece. After maintaining the adhering state for 1 second, the inner die separates from the tubular workpiece and rises to the highest point to complete the paper application. The paper cutting and paper application process is completed in one action, which is simple and efficient. The dual positioning of the positioning part and vacuum adsorption significantly improves the paper application accuracy.

[0027] When the heating plate is pressed together, the foamed silicone undergoes elastic deformation, which allows the high-permeability paper to fully contact and adhere to the end face of the paper tube. At this time, the high-permeability paper hugs the paper tube from three directions: the end face, the outer circle, and the inner circle. The high-permeability paper at the seal presents a slightly concave surface, achieving the purpose of firm sealing.

[0028] The sealed edges are tightly fitted and have a consistent shape after shaping, allowing the glue to dry completely in just 3 seconds. This avoids the problem of the particles drying out and affecting the aroma due to excessive drying time, thereby improving production quality and efficiency. Attached Figure Description
