Description

Technical Field

[0001] This utility model relates to the field of granule processing and packaging technology, specifically to an automatic feeding PVC granule packaging machine. Background Technology

[0002] A PVC granule packaging machine is a specialized piece of machinery for quantitative packaging of PVC granules. PVC granules are widely used in industries such as plastics processing. The function of the packaging machine is to accurately pack PVC granules into packaging bags according to certain weight or quantity requirements for convenient storage, transportation, and sales. Packaging PVC granules requires loading PVC material into the packaging machine, i.e., feeding the machine. This requires a feeding mechanism that uses equipment such as elevators and conveyors to transport the granules from the hopper to the packaging machine.

[0003] For example, patent CN 216375364 U discloses a PVC granule packaging machine, including a material frame, a feeding device, a woven bag fixing device, and a conveying device arranged vertically, with the material frame and feeding device fixed by a frame; PVC granules are placed in the receiving cavity of the material frame and enter the feeding device through the discharge port; the opening of the woven bag is fitted onto the bottom of the woven bag fixing device and fixed by the woven bag fixing device; then the feeding device is activated, causing the PVC granules to be fed into the woven bag for packaging; when the woven bag is full, the woven bag fixing device releases its grip on the woven bag, and the woven bag full of PVC granules falls onto the conveying device under gravity, which is then activated to transport the woven bag containing PVC granules. The sealing device is located on the conveying stroke of the conveying device. When the woven bag passes the opening and sewing device, the opening and sewing device sewn the opening of the woven bag. Before packaging PVC granules, the material frame needs to be loaded so that the material frame can package the PVC granules in time. However, when the conveying speed is greater than the granule feeding speed, a large number of granules will accumulate inside the material frame. Especially when the particle size of the granules is uneven, the granules of different sizes will accumulate inside the material frame. Large granules may form large block structures, while small granules will fill the gaps between large granules. This may cause the granules to block the feeding port. Once the feeding port is blocked, the PVC granules cannot fall normally, and the packaging speed will inevitably be greatly reduced.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing PVC granule packaging machine. Utility Model Content

[0005] The purpose of this invention is to provide an automatic feeding PVC granule packaging machine to solve the problem mentioned in the background art, which is that the PVC granules are of different sizes, and large granules may form large block structures, while small granules will fill the gaps between large granules, which may cause the granules to block the feed port. Once the feed port is blocked, the PVC granules cannot fall normally, and the packaging speed is greatly reduced.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding PVC granule packaging machine, including a hopper, a feeding hopper on one side of the hopper, a packaging module below the feeding hopper, and a sieve plate slidably connected inside the feeding hopper via a slider;

[0007] The lower part of the hopper is connected to a conveying pipe, and a rotating shaft is rotatably connected inside the conveying pipe. Spiral blades are installed on the outer wall of the rotating shaft, and a drive module is installed on one side of the rotating shaft.

[0008] A first gear is mounted on the outer wall of the rotating shaft, and a second gear meshes below the first gear. A drive mechanism for driving the sieve plate is provided on the transmission shaft of the second gear.

[0009] Furthermore, the driving mechanism includes a first connecting rod, which is rotatably connected to both sides of the screening plate. One end of the first connecting rod is rotatably connected to an eccentric wheel, and a rotating column is fixedly connected between the two eccentric wheels. Synchronous pulleys are fixedly connected to the outer wall of the transmission shaft of the second gear, and the two synchronous pulleys are connected by a synchronous belt drive.

[0010] Furthermore, the drive shaft of the second gear is also equipped with an anti-blocking mechanism to prevent the hopper from getting clogged.

[0011] Furthermore, the anti-blocking mechanism includes a cam, which is fixedly connected to the outer wall of the second gear transmission shaft. One end of the cam is rotatably connected to a second connecting rod, and one end of the second connecting rod is rotatably connected to an L-shaped rod. One end of the L-shaped rod is equipped with a sliding block, which is slidably connected to the inner wall of the hopper.

[0012] Furthermore, a discharge hopper is provided on one side of the screening plate, and the discharge hopper is inclined.

[0013] Furthermore, the bottom of the hopper is provided with a discharge port, which is connected to the packaging module.

[0014] Furthermore, the L-shaped rod is positioned below the sieve plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This automatic feeding PVC granule packaging machine uses a drive module to rotate the rotating shaft and spiral blades, which can automatically transport the PVC granules in the hopper to the discharge hopper along the conveying pipe. This eliminates the need for frequent manual material addition, saving labor costs, improving production efficiency, and ensuring the continuity of the packaging process.

[0017] Furthermore, by rotating the rotating shaft, the first gear and the second gear mesh and rotate, thereby driving the eccentric wheel and the first connecting rod to run, so that the screening plate slides back and forth inside the hopper, realizing the automatic screening of PVC particles. Then, the particles that do not meet the requirements are discharged through the discharge hopper, which can effectively separate the particles that do not meet the requirements, ensure that the particles entering the packaging module are of uniform quality, and improve the overall quality of the product.

[0018] Furthermore, the rotation of the second gear drives the anti-blocking mechanism to work, and the sliding block slides on the inner wall of the hopper to agitate the PVC granules, thereby agitating the discharge port of the hopper up and down repeatedly to avoid blockage inside the discharge port, ensuring smooth discharge, reducing downtime for maintenance due to blockage, and improving the stability and reliability of the equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: an automatic feeding PVC granule packaging machine, including a hopper 1, a feeding hopper 2 on one side of the hopper 1, a packaging module 8 below the feeding hopper 2, and a sieving plate 12 slidably connected inside the feeding hopper 2 via a slider; a conveying pipe 3 is connected below the hopper 1, a rotating shaft 4 is rotatably connected inside the conveying pipe 3, a spiral blade 5 is installed on the outer wall of the rotating shaft 4, and a drive module is installed on one side of the rotating shaft 4; a first... A first gear 6 is provided, and a second gear 7 meshes below the first gear 6. A drive mechanism for driving the sieve plate 12 is provided on the drive shaft of the second gear 7. The drive mechanism includes a first connecting rod 11, which is rotatably connected to both sides of the sieve plate 12. An eccentric wheel 10 is rotatably connected to one end of the first connecting rod 11. A rotating column is fixedly connected between the two eccentric wheels 10. Synchronous wheels 9 are fixedly connected to both the rotating column and the outer wall of the drive shaft of the second gear 7. The two synchronous wheels 9 are connected by a synchronous belt.

[0028] In use, first turn on the drive module on the rotating shaft 4 so that the rotating shaft 4 can run. Then the rotating shaft 4 drives the spiral blade 5 to rotate inside the conveying pipe 3. Since the conveying pipe 3 is connected to the hopper 1, the spiral blade 5 can roll the falling particles into the inside of the conveying pipe 3 for transportation, and then discharge them through the other end of the conveying pipe 3. When the rotating shaft 4 rotates, it will drive the first gear 6 to rotate. The first gear 6 drives the second gear 7 that meshes with it to rotate. When the second gear 7 rotates, its transmission shaft drives the synchronous wheel 9 that is fixedly connected to it to rotate. Through the transmission of the synchronous belt, another synchronous wheel 9 fixed inside the eccentric wheel 10 also rotates, thereby driving the rotating column to rotate. The rotating column drives the eccentric wheels 10 at both ends to rotate. The rotation of the eccentric wheels 10 drives the screening plate 12 to slide back and forth in the feed hopper 2 through the first connecting rod 11. The reciprocating sliding of the sieve plate 12 sieves the PVC particles, separating out the particles that do not meet the requirements, and allowing the particles that meet the requirements to enter the subsequent packaging process through the sieve plate 12. During the reciprocating motion, the sieve plate 12 is slidably connected to the inside of the feed hopper 2 through the sliding block 15 to ensure that the sieve plate 12 will not deviate from the direction due to the movement of the first connecting rod 11.

[0029] Example 2: Based on Example 1, an anti-blocking mechanism is also disclosed, the specific structure of which is as follows:

[0030] The anti-blocking mechanism includes a cam 13, which is fixedly connected to the outer wall of the transmission shaft of the second gear 7. One end of the cam 13 is rotatably connected to a second connecting rod 16, and one end of the second connecting rod 16 is rotatably connected to an L-shaped rod 14. One end of the L-shaped rod 14 is equipped with a sliding block 15, which is slidably connected to the inner wall of the hopper 2. A discharge hopper is provided on one side of the screening plate 12, and the discharge hopper is inclined. The bottom of the hopper 2 is provided with a discharge port, which is connected to the packaging module 8. The L-shaped rod 14 is located below the screening plate 12.

[0031] When the drive shaft of the second gear 7 rotates, it drives the cam 13 fixed on its outer wall to rotate. The rotation of the cam 13 drives the L-shaped rod 14 to move through the second connecting rod 16. The sliding block 15 at one end of the L-shaped rod 14 slides on the inner wall of the hopper 2. The sliding block 15 can agitate the PVC granules in the hopper 2 by sliding, preventing the granules from accumulating and clogging the hopper 2, and ensuring smooth feeding. The discharge hopper, which is inclined on one side of the screening plate 12, is used to discharge the PVC granules that do not meet the requirements separated during the screening process, so that these granules can leave the hopper 2 smoothly and avoid affecting the subsequent packaging work. The discharge port at the bottom of the hopper 2 is connected to the packaging module 8. The qualified PVC granules after screening enter the packaging module 8 through the discharge port to realize the automatic packaging of PVC granules. When the L-shaped rod 14 moves, the sliding block 15 at one end can guide the movement of the L-shaped rod 14, so that it can only move up and down, which can better agitate the feeding area below the screening plate 12, prevent the sieved granules from accumulating and clogging in this area, further improve the anti-clogging effect, and ensure smooth feeding.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
