[0034] A telescopic member 7 is provided at the bottom of the square plate 6, and a spring 8 is provided between the telescopic member 7 and the square plate 6. The telescopic member 7 slides left and right and is provided with two first sliding members 11, and each first sliding member 11 slides forward and backward and has two second sliding members 12.

[0035] A limit shell 15 is installed at the bottom of the square plate 6. The bottom of the limit shell 15 is open and a third sliding member 18 is provided for sliding back and forth. A scraper 19 is rotatably connected to the third sliding member 18. A spring 20 is provided at the rotating connection between the scraper 19 and the limit shell 15. The limit shell 15 is located above the two first sliding members 11, and the square plate 6 is located directly above the conveyor belt 2. The monitoring camera 3 can control the hydraulic rod 5.

[0036] It should be noted that the monitoring camera 3 captures images or video signals through the camera and can convert the captured visual signals into electrical signals, thereby controlling the hydraulic rod 5. When the monitoring camera 3 captures the packaging bag, the conveyor belt 2 stops transporting.

[0037] In this embodiment, the front end of the telescopic member 7 is rotatably connected to the first screw 9, the first screw 9 passes through the front ends of the two first sliding members 11 and is threadedly connected thereto, and one side of the first screw 9 passes through the telescopic member 7 and is provided with a first motor 10.

[0038] It should be noted that the first motor 10 drives the first screw 9 to rotate, and the rotation of the first screw 9 can move the first sliding member 11 left and right, thereby indirectly moving the second sliding member 12 left and right.

[0039] In this embodiment, each first sliding member 11 is rotatably connected to a second screw 13 , each second screw 13 passes through two second sliding members 12 and is threadedly connected thereto, and one side of each second screw 13 passes through the first sliding member 11 and is provided with a second motor 14 .

[0040] It should be noted that the second screw 13 is rotated by driving the second motor 14, and the second sliding member 12 can be moved forward and backward by rotating the second screw 13. The position of the second sliding member 12 can be flexibly adjusted by driving the first motor 10 and the second motor 14 to ensure that packaging bags of different sizes can be pressed and fixed.

[0044] It should be noted that the torsion spring is used to ensure that the scraper 19 is more stable and not conducive to rotation when scraping glue, thereby improving the uniformity of the scraped glue. At the same time, the special structure of the first screw 9 and the second screw 13 is set. By rotating the first screw 9 and the second screw 13, the position of the second sliding member 12 can be quickly adjusted, which is suitable for the compression and fixation of packaging bags of different sizes.

[0045] In this embodiment, the telescopic member 7 includes two square rods 701 distributed on the left and right, and two round rods 702 distributed front and back are fixedly installed between the two square rods 701. A telescopic rod 703 is fixedly installed on the front and back sides of the upper surface of each square rod 701. The spring is sleeved on the telescopic rod 703. The telescopic rod 703 passes through the four corners of the square plate 6 and the upper end is clamped on the top of the square plate 6.

[0046] It should be noted that the designed telescopic member 7 not only serves as a carrier of the first sliding member 11 and the second sliding member 12, but also has a spring 8 provided at the upper end. The pressure of the second sliding member 12 on the packaging bag is provided by the spring 8.

[0047] In this embodiment, a partition 1101 is provided in the middle of each first sliding member 11 , and two circular holes 1102 distributed vertically are provided at the front and rear ends of each first sliding member 11 . The circular holes 1102 cooperate with the corresponding round rods 702 .

[0048] It should be noted that the cooperation between the round rod 702 and the round hole 1102 makes the first sliding member 11 more stable when sliding. The purpose of the partition 1101 is to prevent the second sliding member 12 from colliding during relative movement, which may cause damage to the second sliding member 12.

[0049] In this embodiment, each first sliding member 11 is provided with two sliding grooves 1103, and each second sliding member 12 is provided with a slider 1202 on the left and right sides. The slider 1202 cooperates with the corresponding sliding groove 1103, and a rubber block 1201 is provided at the bottom of the second sliding member 12.

[0050] It should be noted that, through the mutual cooperation between the slide groove 1103 and the slider 1202, the second sliding member 12 is more stable when sliding on the first sliding member 11. At the same time, the rubber block 1201 should be located below the telescopic member 7 and the first sliding member 11 to ensure that the rubber block 1201 contacts the packaging bag at the first time to press and fix the packaging bag.

[0052] It should be noted that, through the cooperation between the second slide groove 1501 and the second slider 1801, the third sliding member 18 is more stable when sliding on the limiting shell 15, and the glue on the packaging bag is spread more evenly.

[0053] In summary: the gluing device of the food packaging machine is used to evenly spread the glue on the packaging bag after the packaging bag is glued, and monitor the packaging bag transported on the conveyor belt 2 through the monitoring camera 3. When the packaging bag is found, an electric signal is sent to drive the hydraulic rod 5, and the hydraulic rod 5 pushes the square plate 6 downward, so that the square plate 6, the telescopic member 7 and the first sliding member 11 and the second sliding member 12 on the telescopic member 7 are all moved downward, and the packaging bag on the conveyor belt 2 is pressed and fixed by the second sliding member 12. When the second sliding member 12 contacts the packaging bag and When it is unable to move downward any further, the square plate 6 is allowed to continue moving downward by means of a spring 8 provided on the telescopic member 7. At the same time, a slidable scraper 19 is provided under the square plate 6. The glue is spread evenly by means of the scraper 19. In the process of spreading the glue on the packaging bag evenly, the packaging bag is first fixed and pressed by the second sliding member 12, and then the glue is spread evenly by sliding the scraper 19. This will not cause adhesion between the packaging bag and the scraper 19, and will make spreading the glue safer and more stable, thereby ensuring the safety of the device and the life of the operator.

[0054] Working principle: The device is used to evenly spread the glue on the surface of the packaging bag that has been coated with glue. When the conveyor belt 2 transports the packaging bag through the device, the monitoring camera 3 detects and captures the packaging bag. After capturing the packaging bag, the monitoring camera 3 controls the hydraulic rod 5 to move the square plate 6 downward. When the rubber block 1201 moves to the second sliding member 12 and is pressed against the four corners of the packaging bag, the hydraulic rod 5 continues to drive the square plate 6 downward until the scraper 19 moves to the height for evenly spreading the glue. The hydraulic rod 5 stops moving. At this time, the third motor 17 drives the third screw 16 to rotate, so that the third sliding member 18 drives the scraper 19 to move back and forth to evenly spread the glue. Compared with the traditional spreading of glue on packaging bags, the operation is safer and there will be no adhesion between the packaging bag and the scraper 19.

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
