Description

Technical Field

[0001] The utility model belongs to the technical field of plastic bag production, in particular to a quantitative gluing device for plastic bag production. Background Art

[0002] Plastic bags usually refer to bags made of plastic. Common materials include polyethylene, polypropylene, etc. Plastic bags are widely used in commodity packaging, food packaging, shopping bags, garbage bags and other fields. They are lightweight, durable, and waterproof, so they are widely used in daily life and business. In order to make the plastic bags strong, durable and waterproof, a gluing device is usually used to gluing the surface of the plastic bags.

[0003] After retrieval, the authorization announcement number CN219210432U and the authorization announcement date 2023.06.20 disclose a quantitative gluing device for plastic bag production, including a box body, a pump is fixedly connected to the upper part of the box body, and a glue extraction hose is fixedly connected to the input end of the pump body, a glue storage box is fixedly connected to the other side of the upper part of the box body, and the other end of the glue extraction hose extends into the glue storage box, and a glue outlet hose is fixedly connected to the upper side of the inner wall of the box body, and the lower end of the glue outlet hose is fixedly connected to the upper side of the glue guide hose. A connecting plate is provided under the glue guide hose, and four groups of sliders are equidistantly fixedly connected to one side of the upper part of the connecting plate. The utility model provides a quantitative gluing device for plastic bag production, which drives the upper glue roller to rotate through the driving motor, and when the upper glue roller rotates, it drives the eccentric wheels of the front and rear parts to rotate, and the movable plate is dragged upward through the rotation of the eccentric wheel.

[0004] The prior art uses an eccentric wheel to drive a slider to intermittently push the glue guide tube to achieve intermittent glue flow, so as to avoid the glue being in a state of discharge all the time and causing excessive glue on the surface of the plastic bag. However, in actual use, since the coverage width of the glue cannot be adjusted, when the width of the plastic bag is small, the glue accumulates on the rubber roller outside the width of the plastic bag, which not only affects the amount of glue applied, but also requires manual processing of the glue dripping into the glue collection box, which is inconvenient to use. In addition, the glue used in the prior art is at room temperature, which not only has poor fluidity but also low drying efficiency. For this reason, we provide a quantitative gluing device for plastic bag production to solve the above problems. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-4 The utility model is a quantitative gluing device for producing plastic bags, including a material box 3, the upper side of the material box 3 is open, an electric push rod 1 is arranged inside the material box 3, a baffle 102 is fixed at the bottom of the electric push rod 1, and is used to intermittently block the gluing groove 302 to prevent the glue from being in a discharge state all the time, a gluing groove 302 is opened on the material box 3 corresponding to the lower side of the baffle 102, a mounting box 303 is fixed on the lower wall of the material box 3 at the position where the gluing groove 302 is located, an adjusting block 6 is provided at the front side of the mounting box 303 with clearance fit, a rotating roller 7 is provided below the adjusting block 6, and two rotating rollers 7 are provided, and the exposed length of the discharge trough 3031 is adjusted by moving the adjusting block 6 to achieve the purpose of adjusting the glue coverage width according to the actual width of the plastic bag.

[0030] Specifically, a U-shaped plate 101 is fixed to the upper end of the electric push rod 1 , and the U-shaped plate 101 is fixedly connected to the material box 3 , and vertical plates 304 are fixed to the front and rear side walls of the material box 3 .

[0031] The lower wall of the installation box 303 is arranged in an arc shape, and the installation box 303 is adapted to the corresponding rotating roller 7. A discharge groove 3031 is opened on the lower wall of the installation box 303. The glue passes through the discharge groove 3031 and acts on the rotating roller 7 located on the upper side. The rotating roller 7 rotates to make the glue adhere to the plastic bag to complete the gluing. A convex strip 601 is fixed to the lower wall of the corresponding adjustment block 6 at the position where the discharge groove 3031 is located, and the convex strip 601 is matched with the clearance of the installation box 303. The convex strip 601 is driven by the adjustment block 6 to move to adjust the length of the discharge groove 3031.

[0032] The internal thread of the adjusting block 6 is connected with a rotating rod 602, which does not penetrate the adjusting block 6 to prevent glue from entering the interior of the adjusting block 6. A mounting bracket 3041 is fixed to the side wall of the vertical plate 304 on the outside of the rotating rod 602, and the rotating rod 602 is rotatably connected to the mounting bracket 3041 through a bearing. A rocker 6021 is fixed to the front end of the rotating rod 602, and the rotating rod 602 can be rotated by controlling the rocker 6021.

[0034] The operation process of this embodiment is as follows: when in use, according to the actual width of the plastic bag, the operating wheel 6021 is rotated to drive the rotating rod 602 to rotate, so that the adjusting block 6 drives the convex strip 601 to move. When the convex strip 601 moves to the exposed length of the discharge slot 3031 and the width of the plastic bag, the quantitative gluing operation can be performed. During gluing, the motor 8 drives the rotating roller 7 located on the upper side to rotate. At this time, the plastic bag passes through the two rotating rollers 7 and is located directly below the exposed part of the through slot 302, so that the electric push rod 1 reciprocates and extends, driving the baffle 102 to intermittently block the through slot 302. When the through slot 302 is not in a blocked state, the glue passes through the through slot 302 and enters the installation box 303, and then passes through the discharge slot 3031 to act on the outer peripheral wall of the rotating roller 7 located on the upper side. When the rotating roller 7 located on the upper side rotates, it contacts the gluing part of the plastic bag, so that the glue adheres to the plastic bag to complete the gluing. Specific embodiment 2
