Technical Field

[0001] This utility model relates to the technical field of paper bag adhesive scraping, and in particular to an adhesive scraping device for duckbill bags. Background Technology

[0002] Duckbill bags are a common type of paper bag used in food packaging. They require adhesive to be applied and fixed during the production process.

[0003] Currently, the glue scraping head of paper bags mainly relies on pneumatic glue guns for glue scraping. Specifically, the opening and closing of the pneumatic glue gun is controlled by a solenoid valve to control the amount of glue scraped by the pneumatic glue gun.

[0004] However, the existing pneumatically controlled glue application method has the following shortcomings: due to the low control precision of the pneumatic glue gun, it is difficult to accurately control the glue dispensing amount, which can easily lead to excessive or insufficient glue on the paper bags, resulting in poor glue coating quality and affecting the final product quality of the glued bags. Therefore, in order to improve the glue application quality of paper bags, the glue application device for duckbill bags of this application is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a glue scraping device for duckbill bags that effectively improves the accuracy of glue dispensing and thus improves the glue scraping quality of paper bags.

Detailed Implementation

[0025] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0026] like Figure 1 and Figure 2 As shown, a scraping device 10 for duckbill bags includes a transfer assembly 100 and a scraping assembly 200. The transfer assembly 100 includes a transverse module 110, a support base 120, a lifting drive component 130, and a lifting frame 140. The support base 120 is mounted on the output shaft of the transverse module 110, the lifting drive component 130 is mounted on the support base 120, and the lifting frame 140 is slidably mounted on the support base 120 in a vertical direction and is connected to the output shaft of the lifting drive component 130. The scraping assembly 200 includes a scraping block 210, a top glue plug 220, a top glue motor 230, a screw 240, a closing drive component 250, and a closing block 260. The scraping block 210 is mounted on the lifting frame 140 and has a glue cavity 211. A glue inlet hole 212 is formed on the inner bottom wall of the glue cavity 211. The glue inlet 212 is used to connect to an external glue cartridge. The bottom of the glue scraper block 210 is also provided with a glue outlet 213 that communicates with the glue cavity 211. The top glue plug 220 is slidably mounted on the lifting frame 140 in the vertical direction and is adapted to be inserted into the glue cavity 211. The top glue motor 230 is mounted on the lifting frame 140. The screw 240 is mounted on the output shaft of the top glue motor 230 and is screwed to the top glue plug 220. The closing drive member 250 is mounted on the glue scraper block 210. The closing block 260 is slidably mounted in the glue scraper block 210 in the horizontal direction and is connected to the output shaft of the closing drive member 250. The closing block 260 is provided with a glue passage hole 261. When the closing drive member 250 drives the closing block 260 to slide, the glue passage hole 261 is connected to or misaligned with the glue outlet 213.

[0027] It should be noted that the transverse module 110 is a motor-driven lead screw module. The transverse module 110 is used to span across the conveyor line that transports paper bags, allowing the conveyor line to move the paper bags below the transverse module 110. A support base 120 is mounted on the output shaft of the transverse module 110, and a lifting drive component 130 is mounted on the support base 120, driving the lifting frame 140 to move up and down. Furthermore, a scraper block 210 is mounted on one side of the lifting frame 140, and is located below the transverse module 110. The scraper block 210 is used to apply glue to the paper bags. Furthermore, the scraper block 210 has a glue cavity 211, for example, a circular cavity structure. A glue inlet hole 212 and a glue outlet hole 213 are provided on the inner bottom wall of the glue cavity 211. The glue inlet 212 is bent inside the glue scraper 210 to extend from the top of the glue scraper 210. The glue outlet 213 passes through the glue scraper 210. The top glue plug 220 is slidably mounted on the lifting frame 140 in a vertical direction. Specifically, the top glue plug 220 can only slide up and down relative to the lifting frame 140 and cannot rotate relative to the lifting frame 140. Further, the top glue motor 230 is mounted on the lifting frame 140. The outer side wall of the screw 240 has an external thread, and the top side of the top glue plug 220 has an internal thread hole in a vertical direction. One end of the screw 240 is fixedly mounted to the output shaft of the top glue motor 230, and the external thread of the screw 240 is also screwed into the internal thread hole of the top glue plug 220. Further, the bottom end of the top glue plug 220 is adapted to be inserted into the glue cavity 211, so that the bottom end of the top glue plug 220 and the glue cavity 211 form a sealed space. Thus, when the closing drive 250 causes the closing block 260 to slide relative to the scraper block 210, causing the glue passage 261 to be misaligned with the glue outlet 213, the glue outlet 213 is blocked by the closing block 260. When the top glue motor 230 drives the screw 240 to rotate, causing the top glue plug 220 to rise relative to the scraper block 210, the volume of the glue cavity 211 increases to form a negative pressure. The glue in the glue tube is drawn into the glue cavity 211 through the glue inlet 212. When a certain amount of glue is drawn in... The glue cartridge closes the glue inlet channel, then the closing drive 250 drives the closing block 260 to slide relative to the scraper block 210, making the glue passage 261 connected to the glue outlet 213. Then, the top glue motor 230 drives the screw 240 to rotate in the opposite direction, causing the top glue plug 220 to descend relative to the scraper block 210. At this time, the volume of the glue cavity 211 decreases, and the glue in the glue cavity 211 is squeezed by the top glue plug 220, and then flows out from the glue outlet 213 through the glue hole 261, thus being coated on the paper bag. In this way, by driving the screw to rotate through the top glue motor 230, the feed amount of the top glue plug 220 is precisely controlled, thereby precisely controlling the glue suction amount and glue spraying speed of a single action. Therefore, the accuracy of paper bag glue coating (also called scraping glue) can be effectively improved.

[0028] like Figure 1As shown, in one embodiment, the support base 120 includes a base plate 121, a carrier plate 122, and a plurality of support rods 123. The base plate 121 is disposed on the output shaft of the transverse module 110. One end of each support rod 123 is disposed on the base plate 121, and the axes of each support rod 123 are arranged parallel to each other. The carrier plate 122 is adjustablely disposed on the support rods 123, and the lifting drive component 130 is disposed on the carrier plate 122.

[0029] It should be noted that, in order to facilitate adjustment of the distance between the scraper block 210 and the paper bag, the carrier plate 122 is designed to be adjustable relative to the support rod 123. Specifically, the support rod 123 is a threaded rod, and the carrier plate 122 has a number of through holes corresponding to the number of support rods 123. Two nuts are screwed onto each support rod 123 to clamp the upper and lower sides of the carrier plate 122. In this way, the height of the carrier plate 122 relative to the transverse module 110 is adjustable, and ultimately the height of the lifting frame 140 relative to the transverse module 110 is also adjustable.

[0030] like Figure 1 As shown, in one embodiment, the lifting frame 140 is provided with two guide rods 150, and the two guide rods 150 are respectively inserted through the carrier plate 122.

[0031] It should be noted that the two guide rods 150 are fixedly mounted on the lifting frame 140, and linear bearings are installed on the carrier plate 122, with the guide rods 150 passing through the linear bearings. In this way, the lifting frame 140 can slide vertically relative to the carrier plate 122 via the guide rods 150.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the adhesive scraping assembly 200 further includes a directional block 270, which is disposed on the lifting frame 140, and the top adhesive plug 220 is inserted through the directional block 270 in a vertical direction.

[0033] It should be noted that, in order to ensure that the top rubber plug 220 can only move up and down relative to the lifting frame 140 and not rotate, a non-circular hole is provided on the directional block 270, and the top rubber plug 220 fits through the non-circular hole of the directional block 270. In one embodiment, the directional block 270 has four open sides, and the outer side wall of the top rubber plug 220 is correspondingly set as a tetrahedral structure.

[0034] In one embodiment, both the lifting drive 130 and the closing drive 250 are cylinders. Specifically, both the lifting drive 130 and the closing drive 250 are linear cylinders, so that the lifting drive 130 drives the lifting frame 140 to move up and down. The closing drive 250 drives the closing block 260 to slide laterally relative to the scraper block 210.

[0035] like Figures 1 to 3 As shown, in one embodiment, the glue scraping assembly 200 further includes a glue spraying plate 280, on which a glue extrusion slit 281 is provided. The glue spraying plate 280 is detachably disposed at the bottom of the glue scraping block 210 so that the glue extrusion slit 281 communicates with the glue outlet 213.

[0036] It should be noted that the extrusion seam 281 has a long and narrow porous structure. The glue spraying plate 280 is detachably mounted on the bottom of the glue scraper block 210. In this way, the glue spraying plate 280 with different lengths of extrusion seams 281 can be replaced according to the actual width of glue scraping required for the paper bag. In addition, the long and narrow structure of the extrusion seam 281 ensures that the glue is applied to the paper bag in a planar structure.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment, a sealing ring 290 is also provided on the side of the glue spraying plate 280 near the glue extrusion seam 281. The glue extrusion seam 281 is located inside the sealing ring 290. When the glue spraying plate 280 is placed at the bottom of the glue scraper block 210, the sealing ring 290 abuts against the glue scraper block 210.

[0038] It should be noted that, in order to improve the sealing between the glue spraying plate 280 and the glue scraper 210 and prevent glue from overflowing between them, a sealing ring 290 is installed on the glue spraying plate 280 so that the sealing ring 290 abuts against both the glue spraying plate 280 and the glue scraper 210, thereby improving the sealing performance.

[0039] like Figure 3 As shown, in one embodiment, the inner diameter of the extrusion slit 281 gradually decreases in the direction away from the glue outlet 213. Thus, as the inner diameter of the extrusion slit 281 decreases, the glue is extruded from the extrusion slit 281 and applied to the paper bag in a planar manner, effectively improving the glue application quality of the paper bag.

[0040] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products.
