[0002] Traditional vacuum feeders are used in the injection molding industry. The medium, masterbatch, has good compressive strength, is not easy to break, is non-corrosive, and does not generate much dust. Traditional vacuum feeders are very effective in this application.

[0003] A search revealed a vacuum material feeder disclosed in publication number CN218370499U. The vacuum material feeder includes: a main tank with a feed inlet and a first connection port; a secondary tank with a vacuum port, a second connection port, and an installation port; a connecting pipe, one end connected to the first connection port and the other end connected to the second connection port… While this application allows adjustment of the regulating valve opening according to the size of the material, thereby adjusting the suction force of the vacuum material feeder to correspond to the material size, the regulating valve becomes damaged after prolonged use. Repairing or replacing the damaged valve requires a significant downtime, thus affecting the work process and efficiency.

[0004] In summary, how to perform maintenance or replacement of regulating valves without prolonged downtime is a pressing technical problem that needs to be solved. To address this, we propose a fully automatic vacuum feeder with adjustable suction. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a fully automatic vacuum feeder with adjustable suction, including a main tank, an auxiliary tank disposed outside the main tank, a connecting pipe connecting the main tank and the auxiliary tank, a material sensing sensor disposed in the connecting pipe, a suction pipe disposed on the back side of the main tank, and a vacuum pipe disposed on the auxiliary tank. A three-way pipe is fixedly connected to the bottom end of the auxiliary tank. Both ends of the three-way pipe are provided with annular grooves. An annular pipe is detachably connected inside the annular groove. An adjusting valve is fixedly connected to the end of the annular pipe away from the three-way pipe. Two control valves are symmetrically installed on the bottom side of the three-way pipe.

[0006] According to the technical solution provided in the embodiments of this application, the inner wall of the three-way pipe is provided with a slot, the inner bottom wall of the slot is provided with a limiting groove, the outer side of the annular pipe is fixedly connected with a limiting block, the outer side of the annular pipe is fixedly connected with an annular block, the side of the annular block near the three-way pipe is provided with a sliding groove, the inside of the sliding groove is slidably connected with an insert, the inside of the sliding groove is provided with a connecting rod, and the outside of the connecting rod is sleeved with a spring.

[0007] According to the technical solution provided in the embodiments of this application, one end of the connecting rod is fixedly connected to the insert block, the other end of the connecting rod passes through the annular block and extends to the outside of the annular block, and a carrying plate is fixedly connected to the other end of the connecting rod.

[0008] According to the technical solution provided in the embodiments of this application, one end of the spring is fixedly connected to the insert block, and the other end of the spring is fixedly connected to the inner wall of the slide groove.

[0009] According to the technical solution provided in the embodiments of this application, an annular sealing gasket one is fixedly connected to the inner bottom wall of the annular groove, and an annular sealing gasket two is provided on the outer side of the annular tube, and the annular sealing gasket two is fixedly connected to the annular block.

[0010] According to the technical solution provided in the embodiments of this application, the inner wall of the slide groove is provided with a sliding groove, and a sliding block adapted to the sliding groove is fixedly connected to the insert block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. If one of the regulating valves is damaged, close the control valve closest to it and open the other control valve. This will allow the other control valve to work in conjunction with the three-way valve to ensure normal operation and avoid prolonged downtime of the device when repairing or replacing the regulating valve, which would otherwise affect work efficiency.

[0013] 2. Pull the handle outwards. The movement of the handle moves the connecting rod, which in turn moves the insert block. This causes the insert block to move from the inside of the slot to the inside of the slide. Then, rotate the regulating valve to rotate the limit block to the inside of the slot. Then, move the regulating valve outwards to remove the limit block from the inside of the slot. This allows the regulating valve to be quickly removed and replaced. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] As mentioned in the background section, when the control valve in the existing technology is damaged after long-term use, the machine needs to be shut down for a long time when it needs to be repaired or disassembled and replaced, which affects the work process and efficiency.

[0023] Example:

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a fully automatic vacuum feeder with adjustable suction, comprising a main tank 1, a secondary tank 2 located outside the main tank 1, a connecting pipe 4 connecting the main tank 1 and the secondary tank 2, a material sensing sensor located in the connecting pipe 4, a suction pipe located on the back side of the main tank 1, and a vacuum pipe 3 located on the secondary tank 2. It also includes a controller. A three-way pipe 5 is fixedly connected to the bottom of the secondary tank 2. Both ends of the three-way pipe 5 have annular grooves 12. An annular pipe 10 is detachably connected inside the annular grooves 12. A regulating valve 6 is fixedly connected to the end of the annular pipe 10 away from the three-way pipe 5. Two control valves 7 are symmetrically installed on the bottom side of the three-way pipe 5. Each control valve... The control valve 7 corresponds to a regulating valve 6. If one of the regulating valves 6 is damaged, the control valve 7 closest to this regulating valve 6 will be closed, and the other control valve 7 will be opened. Thus, the other control valve 7, in conjunction with the three-way pipe 5, ensures normal operation and avoids prolonged downtime of the device when the regulating valve 6 is repaired or disassembled and replaced, thereby affecting work efficiency. The regulating valve 6, main tank 1, auxiliary tank 2, connecting pipe 4, material sensing sensor, vacuum tube 3, suction pipe, and controller in this application are all prior art. Their structure and working principle are based on a vacuum suction machine with publication (announcement) number CN218370499U, and will not be described in detail here.

[0025] Please see Figure 2 , Figure 3 and Figure 4 The inner wall of the T-pipe 5 has a slot 11, with the slot opening facing the inside of the T-pipe 5. One end of the slot 11 is open and the other end is closed. The length direction of the slot 11 is parallel to the length direction of the T-pipe 5. A limiting groove 19 is formed on the inner bottom wall of the slot 11, extending circumferentially along the T-pipe 5. A limiting block 15 is fixedly connected to the outer side of the annular pipe 10. The limiting block 15 is located on the outer wall of the annular pipe 10 near the end of the T-pipe 5, and its shape matches the shape of the slot 11. An annular block 13 is also fixedly connected to the outer side of the annular pipe 10. A sliding groove 17 is formed on the side of the annular block 13 near the T-pipe 5, with its length direction parallel to the length direction of the annular pipe 10. The interior of the sliding groove 17... A sliding block 14 is provided, which can slide out of the slide groove 17. When the block 14 slides out to the outside of the annular block 13, it is located on one side of the limiting block 15 and can be close to the limiting block 15. A connecting rod 8 is provided inside the slide groove 17. One end of the connecting rod 8 is fixedly connected to the block 14, and the other end of the connecting rod 8 passes through the annular block 13 and extends to the side of the annular block 13 away from the limiting block 15. A carrying plate 9 is fixedly connected to the other end of the connecting rod 8. The carrying plate 9 is located outside the annular block 13. A spring 18 is sleeved on the outside of the connecting rod 8. One end of the spring 18 is fixedly connected to the block 14, and the other end of the spring 18 is fixedly connected to the inner wall of the slide groove 17. When the spring 18 is in its natural state, the block 14 is located outside the annular block 13.

[0026] In use, the limiting block 15 is aligned with the slot 11, and the annular tube 10 is inserted into the annular groove 12. During the insertion process, the insert 14 is pressed into the slide groove 17 by the end face of the three-way tube 5 and presses the spring 18. The spring 18 is compressed and stores force until the limiting block 15 is inserted into the slot 11 and the limiting block 15 contacts the inner bottom wall of the slot 11. At this time, the end face of the annular block 13 contacts the end face of the three-way tube 5. Then, the annular block 13 is rotated to rotate the limiting block 15 into the limiting groove 19. At this time, the insert 14 is exactly aligned with the slot 11. Due to the pushing force generated by the reset of the spring 18, the insert 14 moves and inserts into the slot 11, thereby limiting the limiting block 15, thus completing the installation of the regulating valve 6.

[0027] Please see Figure 2 An annular sealing gasket 1 (not shown in the figure) is fixedly connected to the inner bottom wall of the annular groove 12. The annular sealing gasket 1 seals the inner bottom wall of the annular groove 12 and the annular pipe 10. An annular sealing gasket 2 16 is provided on the outer side of the annular pipe 10. The annular sealing gasket 2 16 is fixedly connected to the annular block 13. The annular sealing gasket 2 16 seals the annular block 13 and the tee pipe 5. The annular sealing gasket 1 and the annular sealing gasket 2 16 form a two-stage seal to improve the sealing effect.

[0028] Please see Figure 3 The inner wall of the slide groove 17 is provided with a sliding groove. A sliding block that matches the sliding groove is fixedly connected to the insert block 14. The cooperation between the sliding block and the sliding groove limits the position of the insert block 14. When the insert block 14 moves, the insert block 14 drives the sliding block to move inside the sliding groove.

[0029] Working principle: If one of the regulating valves 6 is damaged, the control valve 7 closest to this regulating valve 6 will be closed, and the other control valve 7 will be opened. In this way, the other control valve 7, together with the three-way pipe 5, will be used to ensure normal operation and avoid long downtime of the device when the regulating valve 6 is repaired or disassembled and replaced, which would affect the working efficiency.

[0030] When in use, pull the handle 9 outwards. The movement of the handle 9 moves the connecting rod 8, which in turn moves the insert 14, causing the insert 14 to move from the inside of the slot 11 to the inside of the slide groove 17. Then, rotate the regulating valve 6 to rotate the limiting block 15 to the inside of the slot 11. Then, move the regulating valve 6 outwards to remove the limiting block 15 from the inside of the slot 11, so that the regulating valve 6 can be quickly disassembled and replaced.

[0031] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
