Description

Technical Field

[0001] This application relates to the field of adhesive application technology for packaging machines, and more particularly to an automatic adhesive granule application device for packaging machines. Background Technology

[0002] In the modern packaging industry, the application of automated equipment is becoming increasingly widespread to improve production efficiency and product quality. Among them, the automatic glue granule adding device is a key component used to automatically add hot melt glue granules to the packaging machine.

[0003] In traditional automatic granule feeding devices, a large number of granules usually rush to the bottom outlet at the same time during feeding. Without orderly guidance, they are prone to collision and compression, which leads to accumulation and blockage at the discharge hole at the bottom of the granule cylinder. This causes the granule feeding process to be interrupted, requiring frequent manual cleaning and greatly affecting production efficiency.

[0004] Therefore, to address the problem of blockages occurring at the bottom of the dispensing hole and other locations in traditional automatic granule feeding devices, an automatic granule feeding device for packaging machines can be designed. Typically, a granule guiding structure is installed in the center of the granule cylinder, thereby facilitating the solution of the aforementioned problem. Utility Model Content

[0005] In order to overcome the shortcomings of traditional automatic granule feeding devices, when feeding, a large number of granules usually rush to the bottom outlet at the same time. Without orderly guidance, they are prone to collision and compression, which leads to accumulation and blockage at the discharge hole at the bottom of the granule feeding cylinder. This causes the granule feeding process to be interrupted and requires frequent manual cleaning, which greatly affects the production efficiency.

[0006] The technical solution is as follows: An automatic granule feeding device for a packaging machine includes a granule feeding cylinder, a hopper-shaped cover, a granule anti-blocking guiding mechanism, a fixing and adjusting mechanism, and a feeding pipe; a hopper-shaped cover for guiding granules is installed at the upper edge of the granule feeding cylinder; a granule feeding chamber for accommodating granules is opened inside the granule feeding cylinder; a granule anti-blocking guiding mechanism for preventing granule blockage is provided at the center of the inner side of the granule feeding cylinder; a hopper-shaped guiding slope for concentrating granules is opened at the bottom of the granule feeding chamber; a feeding hole is opened at the center of the bottom of the hopper-shaped guiding slope; a discharge connector for connecting to the feeding hole is provided at the center of the lower end of the granule feeding cylinder; a feeding pipe for conveying granules to a suitable location is provided below the discharge connector; and a fixing and adjusting mechanism for fixing and adjusting the device to a suitable position is provided at the outer end of the granule feeding cylinder.

[0007] Furthermore, the glue particle anti-clogging guiding mechanism includes a drive frame, a drive groove inside the drive frame, a drive motor in the drive groove, an inverted conical cover that is fastened to the top of the drive box, four sets of support frames surrounding the outer end of the drive frame, and four sets of corresponding support blocks surrounding the inner wall of the glue filling tank, with a groove for fixing the support frame at the upper end of the support block.

[0008] Furthermore, the lower end of the drive frame is provided with a rotating shaft, the upper end of which passes through the drive frame and is connected to the drive motor, and the lower end of the rotating shaft is provided with a guide screw, the lower end of which passes through the mounting hole and the discharge connector and extends into the discharge pipe.

[0009] Furthermore, a turntable is fitted around the outer end of the rotating shaft, and three sets of connecting rods are arranged around the lower end of the turntable. Each of the three sets of connecting rods has an anti-blocking block at its lower end. The anti-blocking block fits into the surface of the bucket-shaped guide slope. A control box is provided at the outer front end of the glue-adding cylinder, and the control box is electrically connected to the glue particle anti-blocking guide mechanism.

[0010] Furthermore, the fixing and adjusting mechanism includes a fixing frame located at the outer end of the glue-applying cylinder. Two sets of adjusting tension blocks are provided on the outer end of the fixing frame away from the glue-applying cylinder, and a folded mounting bracket is provided on the outer end of the adjusting tension blocks away from the fixing frame.

[0011] Furthermore, the fixed frame, the two sets of adjusting tension blocks and the angled mounting frame are all provided with movable sleeves at both ends. The fixed frame, the two sets of adjusting tension blocks and the angled mounting frame are connected end to end in sequence through the movable sleeves. Multiple sets of mounting holes are evenly opened on the surface of the angled mounting frame.

[0012] The feeding pipe includes an extension pipe, the upper end of which is connected to the discharge connector, and the lower end of which is provided with a bend for conveying the granules to the molten material location.

[0013] Beneficial Effects: Compared to traditional automatic granule dispensing devices, which often experience blockages at the bottom of the dispensing cylinder, this application addresses this issue by using a guide screw driven by a rotating shaft to orderly push the granules downwards in a spiral structure. This changes the disorderly flow of granules towards the bottom outlet found in traditional devices, reducing the probability of blockages caused by granules colliding and being squeezed together. This allows the granules to smoothly pass through the dispensing hole into the discharge connector and discharge pipe, ensuring the continuity of the dispensing process. A turntable drives an anti-blocking block to move in a circular motion on the hopper-shaped guide slope surface, promptly clearing any granules adhering to the slope and preventing granule accumulation that could block the dispensing hole. This further maintains the smoothness of the dispensing process at the bottom of the dispensing cylinder, reducing the risk of production interruptions due to granule blockage and improving the stability of the packaging machine's automatic granule dispensing system. By adjusting the tension block in conjunction with the movable sleeve and angled mounting bracket, the device can adapt to various complex installation environments, easily handling confined spaces or special locations requiring tilted installation. This significantly improves the versatility and convenience of the automatic granule dispensing device for packaging machines. Attached Figure Description

[0020] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, an automatic granule feeding device for a packaging machine includes a granule feeding cylinder 1, a hopper-shaped cover 2, a granule anti-blocking guiding mechanism 4, a fixing and adjusting mechanism 5, and a feeding pipe 6. The hopper-shaped cover 2 for guiding granules is installed at the upper edge of the granule feeding cylinder 1. The granule feeding chamber 3 is opened inside the granule feeding cylinder 1. The granule anti-blocking guiding mechanism 4 for preventing granule blockage is provided at the center of the granule feeding cylinder 1. The hopper-shaped guiding slope 9 for concentrating granules is opened at the bottom of the granule feeding chamber 3. The feeding hole 10 is opened at the center of the bottom of the hopper-shaped guiding slope 9. The discharge connector 17 connected to the feeding hole 10 is provided at the center of the lower end of the granule feeding cylinder 1. The feeding pipe 6 for conveying granules to a suitable location is provided below the discharge connector 17. The fixing and adjusting mechanism 5 for fixing and adjusting the device to a suitable position is provided at the outer end of the granule feeding cylinder 1.

[0023] The adhesive particle anti-clogging guiding mechanism 4 includes a drive frame 401, a drive groove 402 inside the drive frame 401, a drive motor 403 in the drive groove 402, an inverted conical cover 404 that is fastened to the top of the drive box, four sets of support frames 405 surrounding the outer end of the drive frame 401, and four sets of support blocks 7 corresponding to the support frames 405 surrounding the inner wall of the adhesive filling tank 3. The upper end of the support block 7 has a groove 8 for fixing the support frame 405. The inverted conical cover 404 can prevent adhesive particles from falling into the drive groove 402 and affecting the operation of the motor. On the other hand, its shape helps to guide the adhesive particles to flow to the outside of the drive frame 401 and avoid them accumulating near the drive frame 401.

[0024] The lower end of the drive frame 401 is provided with a rotating shaft 406. The upper end of the rotating shaft 406 passes through the drive frame 401 and is connected to the drive motor 403. The lower end of the rotating shaft 406 is provided with a guide screw 410. The lower end of the guide screw 410 passes through the mounting hole 16 and the discharge connector 17 and extends into the discharge pipe 6. The spiral structure of the guide screw 410 can push the rubber particles downward in an orderly manner, so that the rubber particles can follow a regular pattern during the falling process, and avoid a large number of rubber particles flowing disorderly to the bottom outlet.

[0025] A turntable 407 is sleeved on the outer end of the rotating shaft 406. Three sets of connecting rods 408 are arranged around the lower end of the turntable 407. Each of the three sets of connecting rods 408 is provided with an anti-blocking block 409. The anti-blocking block 409 fits against the surface of the bucket-shaped guide slope 9. A control box 11 is provided at the front end of the glue-adding cylinder 1. The control box 11 is electrically connected to the glue particle anti-blocking guide mechanism 4. The anti-blocking block 409 can clean the glue particles adhering to the surface of the bucket-shaped guide slope 9 in time, preventing the glue particles from accumulating on the slope and blocking the discharge hole 10.

[0026] The discharge pipe 6 includes an extension pipe 18, the upper end of which is connected to the discharge connector 17, and the lower end of the extension pipe 18 is provided with a bend 19 for conveying the granules to the molten position.

[0027] During operation, the operator first adds a sufficient amount of glue granules to the glue filling hopper 3. During the glue filling process, the glue granules are concentrated at the bottom of the glue filling hopper 3 by the bucket-shaped guide slope 9. The operator activates the glue granule anti-blocking guide mechanism 4 through the control box 11, which drives the motor 403 to start working and drives the rotating shaft 406 to rotate. The guide screw 410 at the lower end of the rotating shaft 406 rotates accordingly. The spiral structure of the guide screw 410 pushes the glue granules from the feeding hole 10 in an orderly manner toward the discharge connector 17. At the same time, the turntable 407, which is sleeved on the outer end of the rotating shaft 406, also rotates. The three sets of connecting rods 408 surrounding the lower end of the turntable 407 drive the anti-blocking block 409 to make a circular motion on the surface of the bucket-shaped guide slope 9, which moves the accumulated glue granules to prevent blockage.

[0028] The working principle is based on the drive motor 403 providing power to the entire mechanism. After the drive motor 403 runs, it transmits the power to the guide screw 410 and the turntable 407 through the rotating shaft 406. The guide screw 410 uses the propulsion of the spiral line to keep the rubber particles in an orderly manner during the falling process, avoiding a large number of rubber particles rushing to the bottom outlet at the same time and causing blockage. At the same time, the anti-blocking block 409, driven by the turntable 407, continuously cleans the rubber particles that may stick to the surface of the bucket-shaped guide slope 9, ensuring the unobstructed flow of the discharge hole 10.

[0029] Its beneficial effects are that the original problem of particle clogging is greatly reduced after adopting this application, and the clogging can be quickly resolved through its own anti-clogging function, without the need for long-term manual cleaning, thus significantly improving production efficiency.

[0030] Example 2

[0031] Based on Example 1, such as Figure 1 and Figure 4 As shown, the fixed adjustment mechanism 5 includes a fixed frame 12, which is located at the outer end of the glue-applying cylinder 1. Two sets of adjusting tension blocks 13 are provided on the outer end of the fixed frame 12 away from the glue-applying cylinder 1, and a folded mounting bracket 15 is provided on the outer end of the adjusting tension block 13 away from the fixed frame 12.

[0032] The fixed frame 12, the two sets of adjusting tension blocks 13, and the angled mounting frame 15 are all provided with movable sleeves 14 at both ends. The fixed frame 12, the two sets of adjusting tension blocks 13, and the angled mounting frame 15 are connected end to end in sequence through the movable sleeves 14. The surface of the angled mounting frame 15 is evenly provided with multiple sets of mounting holes 16. By adjusting the tension blocks 13 in conjunction with the movable sleeves 14 and the angled mounting frame 15, they can be stretched or contracted according to the actual installation requirements, thereby flexibly adjusting the distance between the glue-applying cylinder 1 and the installation position to adapt to different installation space requirements.

[0033] During operation, the staff first inserts bolts through multiple sets of mounting holes 16 evenly distributed on the surface of the angled mounting bracket 15, and installs the device in a suitable position on the packaging machine. Then, according to the position of the hot-melting of the glue particles, the staff adjusts the stretching block 13 by stretching or contracting the movable sleeve 14, so that the glue-adding cylinder 1 and the feeding pipe 6 below it move above the position of the hot-melting of the glue particles, which facilitates precise glue addition.

[0034] The working principle is based on the design of the fixed frame 12, the adjusting tension block 13 and the angled mounting frame 15 being connected end to end by the movable sleeve 14. This connection method allows each component to rotate and extend flexibly in different directions. When the adjusting tension block 13 is stretched or contracted, the position and angle of the glue-adding cylinder 1 and the material discharge pipe 6 below it change accordingly, thereby achieving precise positioning of the glue-adding device.

[0035] Its beneficial effects are significant. Due to its flexible adjustability, it can adapt to a variety of complex installation environments. Whether it is a narrow corner or a special location that requires tilting installation, it can easily cope with it, greatly improving the versatility and convenience of the automatic granule feeding device for packaging machines, and ensuring the rapid construction and efficient operation of packaging production lines.
