Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, and more specifically to a vacuum feeding machine. Background Technology

[0002] A vacuum feeder is a device that uses the principle of vacuum adsorption to automate the feeding of materials. It is typically used to adsorb and transport bulk, granular, or powdered materials from the storage area to the feeding port of the working area or processing equipment, thereby improving the automation level and production efficiency of the production line.

[0003] According to patent publication number CN217577392U, published on October 14, 2022, a vacuum feeder is disclosed, including a vacuum feeder body and a feeding hose of the vacuum feeder body. The lower end of the feeding hose is fixedly connected to a functional tube; a bottom tube is slidably connected to the lower part of the outer side of the functional tube; a top tube is slidably connected to the upper part of the outer side of the functional tube; both the bottom tube and the top tube are provided with tightening bolts; a motor is installed on the outer side of the bottom tube; a support rod is fixedly connected to the output end of the lower end of the motor; a frame is rotatably connected to the outer side of the top tube through a rotating shaft; an angle bolt that cooperates with the top tube is provided on the frame; and telescopic devices are installed on both the left and right ends of the frame.

[0004] In the prior art, including the aforementioned patents, the use of a feeding hose in vacuum conveyors typically employs the aforementioned method. The flexibility of the feeding hose facilitates manual handling and movement, allowing for insertion or removal based on the location of the goods and specific circumstances, thus greatly facilitating material loading. However, the common installation method for this feeding hose is direct fixation to the feeding port of the vacuum conveyor body. To reduce resistance and impact from the loading path, the feeding port of the vacuum conveyor body is relatively short. In actual operation, the feeding hose mostly hangs naturally over the feeding port, which is relatively rigid. With repeated swinging and twisting, the feeding hose is prone to compression against the feeding port, and prolonged use can lead to cracks at the compression points. Therefore, the feeding hose lacks adequate support and protection. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 This utility model provides a technical solution, including the following embodiments:

[0027] Example 1

[0028] Combination Figure 4 and Figure 5 As shown, in this embodiment, the driving mechanism for the flipping of multiple support plates 5 is solved, so that the multiple support plates 5 can be flipped synchronously to support the bellows 6.

[0029] Specifically, the drive tube 4 is threaded and rotatably mounted on the outer wall of the feed tube 11, and a hinge rod 13 is fixedly welded to the hinge platform 12. The hinge platform 12 is fixedly welded to the outer wall of the feed tube 11, and the support plate 5 passes through the hinge rod 13. The torsion spring 53 is sleeved on the hinge rod 13, and both ends of the torsion spring 53 are fixedly installed on the support plate 5 and the hinge rod 13, respectively. In the default state, the torsion spring 53 keeps the support plate 5 away from the bellows 6. The protrusion 52 and the support plate 5 are an integral structure, and the protrusion 52 is located on one side of the convex edge 41. A rotating ring 43 is fixedly welded to the drive tube 4. By rotating the rotating ring 43, the convex edge 41 pushes the protrusion 52. At this time, due to the internal pushing of the protrusion 52, the flexible pads 51 of the support plate 5 relative to one end of the protrusion 52 move closer to clamp the bellows 6, and so on. Figure 3 As shown, the integral protrusions 54 on the flexible pads 51 are embedded in the corrugated portions 61, thereby utilizing the engagement between the support plate 5 and the protrusions 54 and the corrugated pipe 6 to achieve tension and fixation of the corrugated pipe 6, thus improving the tension stability of the corrugated pipe 6. Similarly, when multiple flexible pads 51 simultaneously approach and clamp the corrugated pipe 6, the hinge rod 13 deforms and stores force. Then, when the drive tube 4 resets to release the squeezing of the protruding edge 41, the hinge rod 13 releases the stored force to allow the support plate 5 to move away from the corrugated pipe 6 again, thus facilitating subsequent disassembly and replacement of the corrugated pipe 6.

[0030] Example 2

[0031] Combination Figure 3 , Figure 4 and Figure 5 As shown, this embodiment details how to further improve the fixation of the bellows 6 and its quick disassembly and locking. Specifically, by inserting the bellows 6 into the feed pipe 11 and positioning it on one side of the pressure block 3, and then flipping the pressure block 3 towards the bellows 6, multiple pressure blocks 3 press the bellows 6 against the inner wall of the feed pipe 11 to achieve pressure-fitting fixation of the bellows 6. To improve the smoothness between the bellows 6 and the inner wall of the feed pipe 11, such as... Figure 3 As shown, when multiple pressure blocks 3 flip and compress the bellows 6, the hook portion 31 on the pressure block 3 pushes the rolled edge portion 21, causing the insulating pad 2 to be stretched and deformed. The rolled edge portion 21 then deforms and adheres to the bellows 6, making the insulating pad 2 a transition section. Thus, the insulating pad 2 provides shielding and protection for the pressure blocks 3 and improves the smoothness between the bellows 6 and the inner wall of the feed pipe 11. Simultaneously, the rubber material of the rolled edge portion 21 provides a certain sealing effect. Furthermore, the flipping of multiple pressure blocks 3 enables rapid pushing and fixing of the bellows 6, facilitating subsequent disassembly and replacement operations.

[0032] Example 3

[0033] Combination Figure 3 , Figure 4 and Figure 5 As shown, this embodiment further proposes, based on the above two implementation methods, that the curved part 32 provided on the pressure block 3 is located on the moving path of the second end of the drive tube 4. Then, when the drive tube 4 is threaded and rotated on the outer wall of the feed tube 11, the protruding part 52 is pushed by the convex edge 41. At this time, the flexible pads 51 of the support plate 5 at one end relative to the protruding part 52 simultaneously approach and clamp the corrugated tube 6. The integral protrusions 54 provided on the flexible pads 51 are embedded in the corrugated part 61, achieving the effect of pulling, fixing, and supporting the corrugated tube 6.

[0034] Meanwhile, as the drive tube 4 rotates and pushes the protrusion 52, the second end of the drive tube 4 gradually pushes the curved part 32, thereby simultaneously driving multiple pressure blocks 3 to flip. When the multiple pressure blocks 3 flip, they can squeeze the bellows 6 respectively, and the hook part 31 on the pressure block 3 pushes the rolled edge part 21, so that the insulating pad 2 is stretched and deformed. Then, the rolled edge part 21 is deformed and attached to the bellows 6, so that the insulating pad 2 serves as a transition section, thereby achieving the effect of quickly pushing and fixing the bellows 6, as well as the effect of the multiple support plates 5 flipping to synchronously support the bellows 6.

[0035] Example 4

[0036] Combination Figure 3 and Figure 5 As shown, in this embodiment, in order to further improve the sealing effect between the feed pipe 11 and the bellows 6, based on the above-mentioned linkage and the fixing and support of the bellows 6, so as to avoid problems such as air leakage during vacuum suction, it can be seen from the above description that when the drive pipe 4 moves into place, the sealing rubber gasket 42 fixedly installed on the inner wall of the drive pipe 4 covers the through groove 14, thereby using the sealing rubber gasket 42 to further improve the sealing effect of the feed pipe 11 and prevent air leakage from affecting the use of the vacuum feeder.

[0037] Working principle: The corrugated pipe 6 is inserted into the feed pipe 11, and then the drive pipe 4 is threaded onto the feed pipe 11. The drive pipe 4 pushes the protrusion 52, thereby causing multiple support plates 5 to flip and clamp the corrugated pipe 6 simultaneously, increasing the support range for the corrugated pipe 6. The flexible pad 51 also acts as a buffer and reduces the problem of breakage and compression. Furthermore, during the movement of the drive pipe 4, the drive pipe 4 pushes multiple pressure blocks 3 to flip and compress the corrugated pipe 6, thereby achieving rapid pushing and fixing of the corrugated pipe 6. This achieves rapid fixing of the corrugated pipe 6 and improves the protection and support effect of the corrugated pipe 6, reducing damage to the corrugated pipe 6.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
