Detailed Implementation

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figures 1-6 As shown in the figure, the present invention provides a fully automatic vacuum filling machine, including a suction cylinder 1, a feed pipe 2, a vacuum pump 3, and a controller 4. The feed pipe 2 is connected to the suction cylinder 1, and the vacuum pump 3 is connected to the suction cylinder 1. The vacuum pump 3 is electrically connected to the controller 4. The vacuum pump 3 is used to remove the gas in the suction cylinder 1, so that the pressure inside the suction cylinder 1 is lower than the external pressure, and the material is squeezed into the suction cylinder 1 by pressure. The controller 4 is used to control the opening, closing, and output power of the vacuum pump 3. The suction cylinder 1, the feed pipe 2, the vacuum pump 3, and the controller 4 constitute a complete fully automatic vacuum filling machine. The fully automatic vacuum filling machine can use the XAL-F2 type vacuum feeder: suitable for conveying plastic powder, granules, etc., with a conveying speed of up to 300 kg / h and a conveying distance of up to 50 m.

[0029] It should be noted that the controller 4 is equipped with a power cord 5 and a signal line. The power cord 5 is connected to the power supply of the external device, and the signal line is connected to the control equipment such as the computer of the external device for remote control of the controller 4. The bottom of the suction cylinder 1 is equipped with a discharge cylinder 6, which is detachably connected to the suction cylinder 1.

[0030] When filling plastic granules, some of the plastic granules in the raw material may clump together due to factors such as a damp storage area. These large plastic granules can easily cause blockages in the feed pipe 2 and subsequent pipes. Therefore, a guide cylinder 7 is installed at the feed pipe 2, and a large particle interception net 8 is installed inside the guide cylinder 7. The large particle interception net 8 can intercept large plastic granules in the raw material.

[0031] Specifically, a sealing mechanism 9 is provided inside the feed cylinder 7, and a large particle interception net 8 is inserted into the sealing mechanism 9. More specifically, the sealing mechanism 9 includes an inner frame 901, an outer frame 902, and a tapered tube 903. The inner frame 901 abuts against the inner wall of the feed cylinder 7, and the inner frame 901 and the outer frame 902 form a storage tank. The large particle interception net 8 cooperates with the storage tank. The inner frame 901 and the outer frame 902 are detachably connected by bolts. A tapered tube 903 is provided on the side of the outer frame 902 away from the feed pipe 2, and the outer wall of the tapered tube 903 is in contact with the inner wall of the feed cylinder 7.

[0032] To break down the large plastic particles intercepted by the large particle interception net 8, a large particle separation mechanism 10 is provided inside the feed cylinder 7. Specifically, the large particle separation mechanism 10 includes a separation shaft 1001, a support frame 1002, a drive motor 1003, a first sector-shaped pressing block 1004, and a second sector-shaped pressing block 1005. The support frame 1002 is connected to the inner wall of the feed cylinder 7. The separation shaft 1001 is inserted into the support frame 1002 and is connected to the output shaft of the drive motor 1003. The first sector-shaped pressing block 1004 and the second sector-shaped pressing block 1005 are both located on the outer wall of the separation shaft 1001. Figure 4 The spacing between each side wall of the second sector-shaped pressure block 1005 and the large particle interception net 8 and the conical tube 903 is the same, so that the extrusion pressure on the plastic particles is equal at each point.

[0033] The drive motor 1003 drives the separation shaft 1001 to rotate. The separation shaft 1001 can drive the first sector-shaped pressure block 1004 and the second sector-shaped pressure block 1005 to rotate. The first sector-shaped pressure block 1004 and the second sector-shaped pressure block 1005, together with the inner wall of the guide cylinder 7, will squeeze the large plastic particles inside the guide cylinder 7. Under the action of the squeezing force, the plastic particles that are stuck together will gradually separate, which can decompose the large plastic particles into small plastic particles. The small plastic particles can pass through the large particle interception net 8. In this way, the large plastic particles in the raw material can be decomposed, and the blockage of the small pipes inside the filling machine due to the large plastic particles can be avoided.

[0034] It should be noted that both ends of the first sector-shaped pressing block 1004 are provided with a first bevel angle 1006, and both ends of the second sector-shaped pressing block 1005 are provided with a second bevel angle 1007. The first bevel angle 1006 and the second bevel angle 1007 in the first sector-shaped pressing block 1004 and the second sector-shaped pressing block 1005 have a chamfered structure, which allows large plastic particles to enter between the sector-shaped pressing block and the inner wall of the guide cylinder 7, and between the sector-shaped pressing block and the outer wall of the large particle interception net 8 and the conical tube 903. This can fully compress the large plastic particles and prevent the large plastic particles from not being compressed by the sector-shaped pressing block.

[0035] Since both the first sector-shaped pressure block 1004 and the second sector-shaped pressure block 1005 are designed in a sector shape, the center of gravity of the separation shaft 1001 is offset, which can easily cause vibration during rotation. Therefore, a first stabilizing block 1008 is provided on the side of the separation shaft 1001 away from the first sector-shaped pressure block 1004, and a second stabilizing block 1009 is provided on the side of the separation shaft 1001 away from the second sector-shaped pressure block 1005. The first stabilizing block 1008 and the second stabilizing block 1009 are used to keep the center of gravity of the separation shaft 1001 as close to the center line as possible during rotation, so that the separation shaft 1001 can rotate more smoothly.

[0036] It should be noted that the first sector-shaped pressure block 1004 has a cavity inside, and several support plates are installed inside the cavity. The three sides of the support plates are respectively attached to the three inner walls of the cavity.

[0037] In summary, this utility model embodiment provides a fully automatic vacuum filling machine. A guide cylinder 7 and a large particle interception net 8 are installed at the feed pipe 2 to intercept large plastic particles in the raw material. Then, the drive motor 1003 is started, driving the separation shaft 1001 to rotate. The separation shaft 1001 can drive the first sector-shaped pressing block 1004 and the second sector-shaped pressing block 1005 to rotate. The first sector-shaped pressing block 1004 and the second sector-shaped pressing block 1005, along with the inner wall of the guide cylinder 7, will compress the large plastic particles inside the guide cylinder 7. Under the action of the compressive force, the plastic particles that are stuck together gradually separate, breaking down the large plastic particles into smaller plastic particles. These smaller plastic particles can pass through the large particle interception net 8. This effectively breaks down the large plastic particles in the raw material, preventing blockages in the small pipes inside the filling machine due to excessively large plastic particles.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
