Description

Bag body circle mouth device of flat mouth machine

The present invention provides a bag body looping device of a flat mouth machine. The bag body is completely bonded after being folded, and the corners of the bag body are filled with a pivoting electric heating rod to ensure the integrity of the bonding of the loop.

According to the current bag body manufacturing machine, in the process of completing a bag body, multiple process steps are required to give the bag body more additional functions.

In order to give the bag body more additional functions, in the process of the bag body manufacturing machine, the bag mouth is folded into the bag. This is to prevent the bag mouth from producing burrs during the processing process. This is to prevent the bag body from being used. As for the continuous damage of the defects, the above-mentioned bag opening process is produced, which can increase the strength and aesthetics of the bag opening. In the bag opening process, it needs to be completed in multiple processes, and finally the inner folding process is completed. The folding section is glued to the bag body to complete the bag body looping operation. However, the electric heating device is usually stretched into the bag body to press when the loop mouth is hot pressed, so the bag mouth needs to be held up to a certain height, and the width must be slightly larger than the electric heating device It can be implemented smoothly, but if it is implemented according to the above device, the corners on the two sides of the inner fold section must not be completely bonded to the bag body, and the use process will be torn from here, which will cause confusion for users and affect the quality and reputation of the manufacturer. In this case, it is necessary to propose specific improvement plans to meet the needs of industrial progress and further provide users with more choices.

The main purpose of the present invention is to provide a bag body ring opening device of a flat mouth machine, in order to To solve the integrity of the customary ring mouth bonding, use an electric heating rod to fill the corners of the bag body to achieve the purpose of improving the output quality of the bag body.

In order to achieve the above objectives, the technical means and solutions adopted by the present invention are as follows:

The present invention is a bag body ring opening device of a flat mouth machine, which can be opened and closed by two bag opening platforms. The corresponding surfaces of the two bag opening platforms are embedded with suction holes, and the bag is opened. An electric heating plate is arranged outside the platform, which is characterized in that: the front of the bag opening platform is provided with two electric heating rods, which can be set as a pivot, and can be rotated from the bag opening platform to the space between the bag opening platform, and the electric heating rod and the electric heating plate There are a plurality of bumps on the upper and lower surfaces, which can be used as hot pressing points to ensure adhesion, so that the electric heating rod and the electric heating plate can be jointly bonded to the bag opening after the folding.

A soft plastic sheet is laid on the surface of the corresponding surface of the bag opening platform to facilitate the pressing of the bumps of the electric heating rod and the electric heating plate; the soft plastic sheet can be double-layered on the surface of the corresponding surface, and the second layer can avoid attracting The holes are arranged in a staggered arrangement.

The specific features and effects of the present invention are:

1. The cooperation of bumps and soft plastic sheet can improve the adhesion;

2. The electric heating rods close to the two sides of the bag mouth can achieve the integrity of the looping operation;

3. Avoid affecting the quality of the output bag;

The following illustrations and detailed explanations will be used to illustrate the spirit and manner of the present invention. Anyone with ordinary knowledge in the art can change and modify the technology taught by the present invention after understanding the best embodiments of the present invention. It does not depart from the spirit and scope of the present invention.

Please refer to Figures 3 to 4, the bag body ring device of the flat mouth machine of the present invention is aimed at the bag mouth (11) of the bag body (1) after being folded inward, in order to ensure that the inner folding section (12) It is improved by bonding; it is matched by two bag opening platforms (2) that can be opened and combined, and the corresponding surfaces (21) of the two bag opening platforms (2) contacting each other are embedded with suction holes (22), and an electric heating plate (3) is arranged outside the bag opening platform (2), and an electric heating rod (4) is arranged on each of the two front sides of the bag opening platform (2). Plural convex blocks (5) are respectively provided on the upper and lower surfaces of the rod (4) and the electric heating plate (3).

In summary, the surface of the corresponding surface (21) of the bag opening platform (2) is covered with a soft plastic sheet (6) to facilitate the pressurization of the electric heating rod (4) and the protrusion (5) of the electric heating plate (3); The flexible plastic sheet (6) can be double-laminated on the surface of the corresponding surface (21), and the second layer can avoid the suction holes (22) for staggered arrangement.

Please refer to Figures 2 to 5, when the bag body (1) is transported to the second bag opening platform (2), the second bag opening platform (2) will adsorb the suction holes (22) and open the bag The opening (11), the inner folding section (12) needs to be bonded with the bag body (1) after being folded inward; firstly, the heating rods (4) on the two sides of the opened bag opening (11) can be Make a pivot so that the heating rod (4) is located between the bag opening platform (2), and the heating rod (4) is pressed against the two sides of the bag opening (11) to compact the inner folding section (12) Between and the bag body (1), the other bump (5) is located inside Within the range of the folding section (12), after the electric heating rod (4) is actuated, it extends from the electric heating plate (3) to the bag opening platform (2) and is aligned with the electric heating rod (4). The electric heating plate (3) ) The upper bump (5) is also within the range of the inner folding section (12). After completion, the bag opening platform (2) is pressed and pressed to make the heating plate (3) and the upper bump (5) of the heating rod (4) ) Is used as the hot pressing point to bond the inner fold section (12) and the bag body (1) by hot melt. At this time, the soft plastic sheet (6) is set on the corresponding surface (21) of the bag opening platform (2). When pressing, it can be used as a cushion for hot pressing points to ensure that the inner folding section (12) is fused with the bag body (1), so as to complete the bag body ring mouth bonding industry.
