Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive technology, specifically to a packaging device for automatic weighing and sealing of hot melt adhesive. Background Technology

[0002] Hot melt adhesive is a type of malleable adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic, odorless, and an environmentally friendly chemical product. Because it is a solid product, it is easy to package, transport, and store. Its production process is simple, it has high added value, and it boasts high bonding strength and fast processing speed, making it highly popular. Hot melt adhesive packaging equipment is a device for automating the packaging of hot melt adhesive products (such as sticks and granules).

[0003] Most existing hot melt adhesive packaging equipment lacks weighing functionality. It requires first loading the transported hot melt adhesive granules into packaging bags, then weighing the hot melt adhesive in the packaging bags separately, and finally transferring the packaging bags to a sealing machine for final packaging. The packaging process is cumbersome and has relatively low production efficiency. In addition, during transportation, hot melt adhesive granules may clump together. When these clumps of granules enter the packaging bags, they directly affect the accuracy of weighing, causing significant weighing errors and consequently affecting the measurement accuracy of the product.

[0025] Example 1:

[0026] An embodiment of this utility model provides a packaging device for automatic weighing and sealing of hot melt adhesive, such as... Figures 1-4 As shown, the device includes a base plate 2, on which a weighing device 3 and a vertical plate 1 are mounted. On the vertical plate 1, a housing 13 and a controller are mounted. A funnel 10 is provided on the housing 13, and a dispersing component and an electric control valve are mounted on the funnel 10. A support component 5 is provided on the housing 13. A sealing component is also provided on the vertical plate 1. The sealing component is used to seal the packaging. The controller is electrically connected to the weighing device 3, the electric control valve, and the sealing component.

[0027] The controller is pre-set to weigh the hot melt adhesive. After startup, the electric control valve can be opened separately to allow the particles to fall into the opened packaging bag. At the same time, the weighing device 3 transmits the weight data to the controller in real time. When the weight reaches the set value, the controller immediately closes the electric control valve to stop the material from falling. Then, the sealing assembly is started to seal the packaging bag. After completion, the sealing assembly is reset and waits for the next round of operation.

[0028] The working principle and beneficial effects of the above technical solution are as follows: In use, the packaging bag is placed on the opening member 5, and the opening of the packaging bag is opened by the opening member 5. The electric control valve is opened, and the hot melt adhesive particles enter from the funnel 10. The dispersing component disperses the particles. After the particles fall into the packaging bag, the weighing device 3 on the bottom plate 2 weighs them. When the weight reaches the set value, the controller controls the electric control valve to close and stop the material from falling. Then the sealing component is started to seal the opening of the packaging bag, and the packaging is completed.

[0029] By integrating the weighing device 3 with the sealing assembly and achieving linkage control through the controller, the cumbersome steps of weighing separately and transferring to the sealing machine in traditional packaging are eliminated. The filling, weighing, and sealing processes are integrated into one, effectively simplifying the packaging process and significantly improving production efficiency. Secondly, the dispersing component installed on the funnel 10 can disperse the hot melt adhesive particles that may clump together during transportation, preventing clumps of particles from directly entering the packaging bag, reducing weighing errors caused by particle clumping, and ensuring the stability of product measurement accuracy.

[0030] Example 2:

[0031] Based on the above embodiment 1, as follows Figure 1 As shown, the dispersing component includes a motor 8, which is fixedly mounted on the funnel 10. The output end of the motor 8 is fixedly connected to a rotating rod 7, which rotates and extends into the funnel 10. A dispersing block 9 is also fixedly mounted on the rotating rod 7.

[0032] One of the features is that an end cap can be installed on the funnel 10, allowing the output component that conveys the hot melt adhesive particles to pass through the end cap and extend into the funnel. This way, when the dispersing block 9 rotates at high speed to disperse the particles, the end cap forms a closed space, effectively preventing the hot melt adhesive particles from overflowing the funnel due to collision and splashing. This reduces material waste and keeps the surrounding environment of the equipment clean.

[0033] The working principle and beneficial effects of the above technical solution are as follows: When hot melt adhesive particles enter the funnel 10, the motor 8 starts and drives the rotating rod 7 to rotate, and the dispersing block 9 on the rotating rod 7 rotates synchronously with it; during the rotation, the dispersing block 9 collides and stirs with the hot melt adhesive particles in the funnel 10, breaking and dispersing the clumps of particles that may form during transportation, so that the particles fall through the funnel in a loose state; the particle distribution is more uniform, and after falling into the packaging bag, it can reduce the weighing error caused by the difference in particle bulk density, and further improve the measurement accuracy.

[0034] Example 3:

[0035] Based on the above embodiment 2, such as Figure 1 , Figure 4 As shown, the molding assembly includes a second motor 20, which is fixedly mounted on the rear side wall of the vertical plate 1. A fixing block 24 is also fixedly mounted on the rear side wall of the vertical plate 1. A bidirectional threaded rod 22 is fixedly connected to the output end of the second motor 20, and the bidirectional threaded rod 22 is rotatably connected to the fixing block 24.

[0036] Preferably, a movable block 21 is symmetrically threaded onto the bidirectional threaded rod 22, a connecting rod is fixedly installed on the front side of the movable block 21, and a sliding groove 23 is symmetrically opened on the vertical plate 1. The connecting rod passes through the sliding groove 23 and is slidably connected to the sliding groove 23. A plastic seal 4 is fixedly installed on the front side of the connecting rod.

[0037] The working principle and beneficial effects of the above technical solution are as follows: When the controller controls the sealing assembly to work, the controller starts the second motor 20, which drives the bidirectional threaded rod 22 to rotate. The bidirectional threaded rod 22 drives the moving block 21 to move towards each other. The moving block 21 drives the sealing component 4 to move synchronously through the connecting rod. The two sealing components 4 move towards each other and fit together. After sealing is completed, they move in the opposite direction to reset. Through the guiding action of the moving block 21, the connecting rod and the slide 23, the stable opening and closing of the sealing component 4 is achieved, ensuring the alignment accuracy and pressure uniformity during sealing, improving the sealing quality and making it more practical.

[0038] Example 4:

[0039] Based on the above embodiments 1-3, as follows Figures 1-3 As shown, the box 13 is designed as a hollow cube.

[0040] Preferably, a motor 11 is fixedly installed at an eccentric position on the housing 13, and a rotating rod 14 is fixedly connected to the lower output end of the motor 11. The rotating rod 14 extends into the housing 13 and a gear 12 is fixedly installed at the lower end of the rotating rod 14.

[0041] Preferably, a disc 6 is provided inside the housing 13, and a connecting ring 15 is fixedly provided on the disc 6. The connecting ring 15 is rotatably connected to the upper side wall of the housing 13. A circular groove is provided in the center of the disc 6, and a through groove is provided through the housing 13. The circular groove, the through groove and the discharge end of the funnel 10 are positioned opposite each other. A toothed plate is fixedly provided on the periphery of the disc 6, and the toothed plate is meshed with the gear 12.

[0042] Preferably, the disc 6 has several arrayed arc-shaped grooves 18, and a sliding rod 16 is slidably fitted inside the arc-shaped grooves 18. A sliding block 17 is fixedly installed at the lower end of the sliding rod 16.

[0043] Preferably, a plurality of sliding grooves 19 are provided on the lower inner wall of the housing 13, and a sliding block 17 is slidably disposed in the sliding groove 19, with the lower end of the sliding block 17 fixedly connected to the support member 5.

[0044] Preferably, one of the supporting parts 5 is provided with a point control button, which is electrically connected to the motor 311.

[0045] The working principle and beneficial effects of the above technical solution are as follows: First, put the packaging bag onto several expansion parts 5, press the control button to start motor 3 11, motor 3 11 drives the rotating rod 14 to rotate, which in turn causes the gear 12 at the lower end to rotate synchronously. The rotation of gear 12 will drive the disc 6 to rotate inside the upper side wall of the box 13 through the tooth plate (the circular groove in the center of the disc 6, the through groove of the box 13 and the discharge end of the funnel 10 are aligned to ensure that the material discharge channel is unobstructed); when the disc 6 rotates, the arc-shaped grooves 18 distributed in an array on its surface will drive the sliding rod 16 to slide along the groove, and the sliding block 17 at the lower end of the sliding rod 16 will slide synchronously in the sliding groove 19 on the lower inner wall of the box 13. The sliding block 17 drives the expansion parts 5 to open or close. After opening to a suitable position (this position is determined by the user), press the control button again to turn off motor 3 11.

[0046] Through the mechanical linkage of components such as motor 11, gear 12, disc 6, and arc groove 18, the stable opening and closing of the support component 5 is achieved, which can accurately adapt to packaging bags of different specifications, ensuring that the bag opening is fully open when filling and avoiding the spillage of particles; the array of arc grooves 18 and sliding grooves 19 cooperate to make the multiple support components 5 move synchronously and the opening and closing amplitude uniform, which improves the support stability of the packaging bag and makes it more practical.

[0047] 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.
