Description

Technical Field

[0001] This utility model relates to the field of high-speed box gluing machines, and in particular to a starch glue quantitative supply device for high-speed box gluing machines. Background Technology

[0002] The high-speed carton gluing machine starch glue quantitative supply device is an advanced piece of equipment for automated packaging production. Through a high-precision metering pump and intelligent control system, it can adjust the starch glue delivery volume and coating speed in real time, ensuring the stability and accuracy of glue supply when the carton gluing machine is running at high speed. The device is made of corrosion-resistant materials, which greatly improves the efficiency and product quality of the packaging production line, while reducing manual intervention and raw material waste.

[0003] Existing high-speed box gluing machines typically use a fixed-height rotating blade to scrape the glue outlet tube during cleaning. Since the blade cannot be adjusted up and down, it is difficult to completely remove the residual glue on the upper part of the inner wall of the glue outlet tube. This design flaw makes it easy for the starch glue near the tube opening to accumulate and solidify, which not only reduces cleaning efficiency but may also affect the subsequent glue dispensing accuracy, ultimately leading to a decrease in box gluing quality and an increase in equipment maintenance costs.

[0004] Therefore, in response to the problem that the existing starch glue metering device for high-speed carton gluing machines usually uses a blade to rotate and scrape when cleaning the glue outlet tube, the height of the blade cannot be adjusted during scraping, resulting in the starch glue adhering to the upper part of the glue outlet tube not being able to be scraped off smoothly and the cleaning quality being low, there is an urgent need to design a new type of starch glue metering device for high-speed carton gluing machines. Utility Model Content

[0005] To overcome the problem that the existing high-speed carton gluing machine's starch glue metering device typically uses a blade to rotate and scrape the glue outlet tube during cleaning, and the blade height cannot be adjusted during scraping, resulting in the starch glue adhering to the upper part of the glue outlet tube not being able to be scraped off smoothly, and the cleaning quality is low.

[0006] The technical solution of this utility model is as follows: a high-speed box-making machine starch glue quantitative supply device, including a glue tube; it also includes a first mounting plate, an electric push rod, a second mounting plate, a rotating assembly, a third mounting plate, a second drive motor, a turntable, and scrapers. A discharge pipe is installed at the bottom of the glue tube, and the first mounting plate is installed at the upper outer side of the discharge pipe. An electric push rod is installed at the bottom right side of the first mounting plate. The second mounting plate is slidably connected to the body of the discharge pipe at the lower side of the first mounting plate. The telescopic end of the electric push rod is connected to the upper side of the second mounting plate. A rotating assembly is installed at the upper right side of the second mounting plate. The bottom of the rotating assembly passes through the second mounting plate and is connected to the third mounting plate. A second drive motor is installed at the upper left side of the third mounting plate. The output end of the second drive motor is connected to the turntable. Multiple scrapers distributed in a circular pattern are installed at the top edge of the turntable.

[0007] Preferably, by setting an electric push rod, during operation, its telescopic end pushes the second mounting plate to slide up and down along the outer wall of the discharge pipe. While the second mounting plate moves, it drives the third mounting plate to move synchronously through a rotating component, thereby inserting the scraper into the inside of the discharge pipe and making it fit against the inner wall of the discharge pipe. Then, the second drive motor is started, and its output end can drive the turntable to rotate, so that the scraper can clean the inner wall of the discharge pipe. At the same time, in conjunction with the back and forth extension and retraction of the electric push rod, the scraper can be driven to extend and retract up and down while rotating and scraping, thereby improving the scraping quality. This solves the problem that the existing high-speed box gluing machine starch glue quantitative supply device usually uses a blade to rotate and scrape when cleaning the glue discharge pipe. During scraping, the height of the blade cannot be adjusted, resulting in the starch glue adhering to the upper part of the glue discharge pipe not being able to be scraped off smoothly, resulting in low cleaning quality.

[0008] Preferably, the rotating assembly includes a first drive motor and a rotating shaft; the first drive motor is mounted on the top right side of the second mounting plate, the output end of the first drive motor passes through the second mounting plate and is connected to the rotating shaft, and the bottom of the rotating shaft is connected to the top of the third mounting plate.

[0009] Preferably, two symmetrical connecting rods are bolted to the top right of the third mounting plate, and a stop plate is provided on the top of the two connecting rods.

[0010] Preferably, a bracket is connected to the lower part of the inside of the hose, and a drive shaft is rotatably connected to the top of the bracket. A spiral blade is installed on the outer surface of the drive shaft.

[0011] Preferably, a top cover is installed on the top of the hose, and a driven gear is connected through the top of the drive shaft through the top cover. A driving gear is rotatably connected to the top of the top cover located on the side of the driven gear. The driven gear meshes with the driving gear. A mounting bracket is provided on the top of the top of the top cover located behind the driving gear. A third drive motor is installed on the top inner side of the mounting bracket, and the output end of the third drive motor is connected to the driving gear.

[0012] Preferably, a fixing plate is installed on the bottom outer side of the mounting bracket, and fixing bolts are connected to the top corners of the fixing plate. The fixing plate is fixed to the top cover by fixing bolts.

[0013] Preferably, two symmetrical clamps are welded to the outside of the hose, and connection holes are provided at both the left and right ends of the front side of the clamps.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up an electric push rod as the driving element, the linear motion of the extension end of the electric push rod pushes the second mounting plate to move axially along the outer wall of the discharge pipe during operation. The movement of the second mounting plate drives the third mounting plate to move synchronously through the rotating assembly, so that the scraper installed on the third mounting plate can be accurately inserted into the inner cavity of the discharge pipe and form a tight contact with the pipe wall. Then, the second drive motor is started, and its output shaft drives the turntable to rotate, which drives the scraper to perform circumferential scraping on the inner wall of the discharge pipe. During this process, the reciprocating extension and retraction motion of the electric push rod causes the scraper to generate axial feed motion while rotating and scraping, forming a spiral cleaning trajectory, thereby significantly improving the scraping effect and cleaning quality of the inner wall of the discharge pipe.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment: a high-speed box-making machine starch glue quantitative supply device, including a glue tube 1; it also includes a first mounting plate 3, an electric push rod 4, a second mounting plate 5, a rotating assembly, a third mounting plate 7, a second drive motor 8, a turntable 9, and a scraper 10. A discharge pipe 2 is installed at the bottom of the glue tube 1. The first mounting plate 3 is installed on the upper outer side of the discharge pipe 2. The electric push rod 4 is installed on the bottom right side of the first mounting plate 3. The second mounting plate 5 is slidably connected to the body of the discharge pipe 2 below the first mounting plate 3. The telescopic end of the electric push rod 4 is connected to the upper side of the second mounting plate 5. A rotating assembly is installed on the upper right side of the second mounting plate 5. The bottom of the rotating assembly passes through the second mounting plate 5 and is connected to the third mounting plate 7. A second drive motor 8 is installed on the upper left side of the third mounting plate 7. The output end of the second drive motor 8 is connected to a turntable 9. Multiple scrapers 10 are installed near the top edge of the turntable 9 in a circular pattern. By setting an electric push rod 4, the telescopic end of the electric push rod 4 pushes the second mounting plate 5 to move up and down along the outer wall of the discharge pipe 2. At the same time, the rotating component drives the third mounting plate 7 to move synchronously, so that the scrapers 10 are inserted into the discharge pipe 2 and close to the inner wall. Then, the second drive motor 8 is started, and its output end drives the turntable 9 to rotate, which drives the scrapers 10 to scrape and clean the inner wall of the discharge pipe 2. At the same time, the reciprocating extension and retraction of the electric push rod 4 causes the scrapers 10 to move up and down while rotating and scraping, forming a compound motion, thereby improving the thoroughness and uniformity of scraping.

[0024] Please see Figures 1-4In this embodiment, the rotating assembly includes a first drive motor 61 and a rotating shaft 62. The first drive motor 61 is installed on the top right side of the second mounting plate 5. The output end of the first drive motor 61 passes through the second mounting plate 5 and is connected to the rotating shaft 62. The bottom of the rotating shaft 62 is connected to the top of the third mounting plate 7. By setting the first drive motor 61, its output end can drive the rotating shaft 62 to rotate during operation. When rotating, it can drive the third mounting plate 7 to rotate, thereby moving the turntable 9 and the scraper 10 away from the port of the discharge pipe 2, without affecting the normal glue discharge of the discharge pipe 2. The top of the third mounting plate 7 is close to the... Two symmetrical connecting rods 11 are bolted to the right position. A baffle 24 is set on the top of the two connecting rods 11. By setting the baffle 24, the third mounting plate 7 can also drive the baffle 24 to move to the lower side of the discharge pipe 2 when rotating, thereby shielding the end of the discharge pipe 2 and preventing glue leakage. A bracket 12 is connected to the lower part of the inside of the glue tube 1. A drive shaft 13 is rotatably connected to the top of the bracket 12. A spiral blade 14 is installed on the outer surface of the drive shaft 13. By setting the drive shaft 13 and the spiral blade 14, the drive shaft 13 can drive the spiral blade 14 to rotate synchronously when rotating, thereby realizing the spiral extrusion function.

[0025] Please see Figures 1-5 In this embodiment, a top cover 15 is installed on the top of the hose 1. A driven gear 16 is connected to the top of the drive shaft 13 through the top cover 15. A drive gear 17 is rotatably connected to the top of the top cover 15 at the side position of the driven gear 16. The driven gear 16 meshes with the drive gear 17. A mounting bracket 18 is provided on the top of the top of the top cover 15 at the rear side of the drive gear 17. A third drive motor 19 is installed on the top inner side of the mounting bracket 18. The output end of the third drive motor 19 is connected to the drive gear 17. By setting the third drive motor 19, its output end can drive the drive gear 17 to rotate during operation. When the drive gear 17 rotates, it can drive the driven gear 16, which meshes with it, to rotate synchronously. When the driven gear 16 rotates, it can drive the drive shaft 13 to rotate, thereby... To achieve automatic glue dispensing, operators can set the motor's running time and speed via the controller to achieve quantitative glue dispensing. A fixing plate 20 is installed on the bottom outer side of the mounting frame 18, and fixing bolts 21 are connected to the top corners of the fixing plate 20. The fixing plate 20 is fixed to the top cover 15 by the fixing bolts 21. By setting the fixing plate 20 and fixing bolts 21, the fixing strength of the mounting frame 18 can be strengthened, thereby improving the stability of the third drive motor 19. Two symmetrical clamps 22 are welded to the outside of the glue tube 1. Connection holes 23 are opened on the left and right ends of the front side of the clamps 22. By setting the clamps 22 and connection holes 23, it is easy for operators to connect the glue tube 1 to the body of the glue box machine with screws, improving the ease of installation.

[0026] During operation, the third drive motor 19 is started, which drives the drive gear 17 to rotate. The drive gear 17, in conjunction with the driven gear 16, drives the transmission shaft 13 and the spiral blade 14 to rotate, thereby extruding the starch glue inside the glue tube 1 from the discharge pipe 2. After extrusion, the first drive motor 61 is started, which drives the third mounting plate 7 to rotate, moving the turntable 9 to the bottom of the discharge pipe 2. Then, the electric push rod 4 is started, which moves the third mounting plate 7 upward, allowing the scraper 10 to enter the discharge pipe 2. Inside, it fits against the inner wall of the discharge pipe 2. Then, the second drive motor 8 is started, and its output end drives the turntable 9 and scraper 10 to rotate. At the same time, the electric push rod 4 extends and retracts, so that the scraper 10 forms a spiral cleaning trajectory to scrape off the starch glue adhering inside the discharge pipe 2. After the glue is removed, the first drive motor 61 is started, and its output end drives the third mounting plate 7 to rotate again, so that the baffle 24 moves to a position directly below the discharge pipe 2. The electric push rod 4 retracts, covering the port of the discharge pipe 2 with the baffle 24 for protection.

[0027] Through the above steps, by setting an electric push rod 4, the electric push rod 4 drives the second mounting plate 5 to move axially along the discharge pipe 2, and at the same time drives the third mounting plate 7 to move synchronously, so that the scraper 10 is accurately inserted into the discharge pipe 2 and adheres to the inner wall. Then, the second drive motor 8 drives the turntable 9 to rotate, so that the scraper 10 scrapes in the circumferential direction while superimposed with the reciprocating motion of the electric push rod 4, forming a spiral cleaning trajectory, thereby achieving efficient and thorough removal of residues on the inner wall of the discharge pipe 2. This solves the problem that the existing high-speed box gluing machine starch glue quantitative supply device usually uses a blade to rotate and scrape when cleaning the glue discharge pipe 1. During scraping, the height of the blade cannot be adjusted, resulting in the starch glue adhering to the upper part of the glue discharge pipe 1 not being able to be scraped off smoothly, resulting in low cleaning quality.
