Description

TECHNICAL FIELD

[0001] The utility model relates to food bag paper bag machine technical field, concretely is a food bag paper bag machine with gluing mechanism. BACKGROUND

[0002] Food bag paper bag machine, also known as food paper bag machine or full-automatic food paper bag machine, is an automatic device for producing environment-friendly paper bags through edge folding, shaping, bag cutting, gluing, bottom folding and bottom pasting. The device is mainly used for producing various shopping bags, clothing bags, leisure food bags, bread bags, etc. The produced paper bags are non-toxic, odorless, and pollution-free, and have good printing performance. They can print graphics and text according to user requirements, and are ideal equipment for producing various food packaging bags. The gluing mechanism on the current device mostly uses a combination of a rubber tube and a nozzle, but the rubber tube and the nozzle are prone to blockage.

[0003] Chinese patent CN215784446U discloses a gluing device for food bag paper bag machine. After the food bag passes between the roller and the gluing disc, it is placed on the roller and moves with the roller. The transmission disc and the gluing disc are tangent to the food bag. The transmission disc rotates with the food bag and drives the gluing disc to rotate. One end of the gluing disc is located in the glue storage box. When it rotates, it transfers glue to the food bag to complete the gluing. It can improve the gluing efficiency and ensure the gluing quality.

[0004] During the bag production process, different customers have different requirements for packaging bags, and the thickness of the paper used is often different. However, the above-mentioned patent is not convenient to adjust the distance between the roller and the gluing disc, which leads to the problem that the glue cannot be evenly applied to the surface of the paper when processing packaging bags of different thicknesses, affecting the product quality. Moreover, the glue has poor flowability in the glue storage box, and the glue is prone to precipitation and clumping, further exacerbating the uneven gluing problem. UTILITY MODEL CONTENTS

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4 This utility model provides a food bag paper bag machine with a gluing mechanism, including a food bag paper bag machine body 100, on which a gluing mechanism 200 is provided. The gluing mechanism 200 includes a glue storage tank 201 formed on the surface of the food bag paper bag machine body 100. Fixed blocks 202 are installed on both sides of the surface of the food bag paper bag machine body 100 along the length direction of the glue storage tank 201. Adjusting blocks 203 are installed above the fixed blocks 202 through a height adjustment mechanism 300. Rollers 204 are rotatably installed on the opposite surfaces of the two adjusting blocks 203. A motor 205 is installed on the outer surface of one of the fixed blocks 202. The end of the output shaft of the motor 205 is connected to a connecting shaft 206. A glue application disc 207 is installed at the end of the connecting shaft 206. The outer edge of the glue application disc 207 is disposed in the glue storage tank 201. A stirring shaft 208 is rotatably mounted inside the glue storage tank 201. Spiral blades 209 are provided on the outer surface of the stirring shaft 208. A transmission mechanism 400 is provided between the stirring shaft 208 and the connecting shaft 206.

[0027] In use, the paper is placed between the roller 204 and the gluing tray 207, and the height of the roller 204 is adjusted by the transmission cooperation of the height adjustment mechanism 300 and the drive mechanism 500 to ensure that the gluing tray 207 can fully contact the paper. Then, during the paper feeding process, the motor 205 is started, and the motor 205 drives the connecting shaft 206 to rotate, which in turn drives the gluing tray 207 to rotate, so that gluing can be performed during the paper feeding process.

[0028] Furthermore, since the glue applicator 207 is driven independently by the motor 205, the glue applicator 207 can reliably apply glue to the paper. In the prior art, the glue applicator 207 is driven to rotate by friction transmission, which is not stable enough and is prone to slippage, thus affecting the uniformity of glue application.

[0029] During the gluing process, the transmission mechanism 400 drives the spiral blades 209 to stir the glue, thereby increasing the fluidity of the glue, preventing sedimentation and clumping, and further improving the gluing quality.

[0030] Preferably, the height adjustment mechanism 300 includes two limiting rods 301 mounted on the upper surface of the fixed block 202, and the adjusting block 203 is slidably mounted on the two limiting rods 301. A screw 302 is rotatably mounted on the upper surface of the fixed block 202 between the two limiting rods 301, and the upper end of the screw 302 passes through to the upper side of the adjusting block 203 and is threadedly connected to it. A driving mechanism 500 is provided between the two fixed blocks 202, and the driving mechanism 500 can simultaneously drive the two screws 302 to rotate.

[0031] Two limit rods 301 limit the adjustment block 203, so that the adjustment block 203 can only move along the height direction. Since the adjustment block 203 and the screw 302 are connected by a thread, when the screw 302 is rotated, the adjustment block 203 can be driven to rise and fall, thereby adjusting the height of the roller 204.

[0032] Preferably, the drive mechanism 500 includes an L-shaped plate 501 mounted on the outer surface of the fixed block 202, a rotating shaft 502 rotatably mounted between the two L-shaped plates 501, worm gears 503 are provided on both sides of the outer surface of the rotating shaft 502, a worm wheel 504 is mounted on the top of the screw 302, and the two worm gears 503 are respectively meshed with the two worm wheels 504.

[0033] When the rotating shaft 502 is rotated, it can drive the two worms 503 on its surface to rotate simultaneously. Since the worms 503 and worm wheels 504 mesh with each other, it can achieve the purpose of driving the two screws 302 to rotate simultaneously, thereby adjusting the height of the roller 204.

[0034] Preferably, the transmission mechanism 400 includes a groove 401 formed on the surface of the food bag paper bag machine body 100, the end of the stirring shaft 208 passes through the groove 401 and is rotatably connected to its inner wall, and pulleys 402 are installed on the outer surfaces of the stirring shaft 208 and the connecting shaft 206, and a transmission belt 403 is fitted on the outer surfaces of the two pulleys 402 together.

[0035] When the motor 205 drives the connecting shaft 206 to rotate, under the transmission action of the pulley 402 and the transmission belt 403, it can drive the stirring shaft 208 to rotate simultaneously. The stirring shaft 208 can drive the spiral blades 209 to stir the glue.

[0036] Preferably, a heating plate 600 is provided inside the glue storage tank 201.

[0037] Heating the adhesive with the heating plate 600 can further improve its fluidity, avoid poor fluidity due to low temperature, and improve the application effect.

[0038] Preferably, a knob is installed at the end of the rotating shaft 502.

[0039] The knob allows for easy manual rotation of the shaft 502.

[0040] Preferably, there are two spiral blades 209, and the two spiral blades 209 are symmetrically distributed on both sides of the upper rubber disk 207.

[0041] Since the two spiral blades 209 are symmetrically distributed and rotate in opposite directions, when the motor 205 rotates, the two spiral blades 209 can push the glue towards the glue tray 207, thereby further improving the fluidity of the glue near the glue tray 207 and improving the uniformity of glue application.

[0042] Preferably, motor 205 is a servo motor.

[0043] The servo motor has high precision and can control the rotation speed of the connecting shaft 206 to match the speed of paper feeding during the production process, thereby ensuring the uniformity of glue application and avoiding situations where the glue application tray 207 rotates too slowly, resulting in a reduction in the amount of glue applied, or rotates too fast, resulting in an increase in the amount of glue applied.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
