Description

Technical Field

[0001] This application relates to the field of vacuum feeders, and more specifically, to a vacuum feeder. Background Technology

[0002] Vacuum conveyors, also known as vacuum feeders, are dust-free, closed-loop conveying devices that use vacuum suction to transport granular and powdery materials. They utilize the pressure difference between the vacuum and the ambient air to create gas flow within the pipe, which in turn moves the material, thus completing the conveying process. They are widely used in various powder manufacturing industries.

[0003] Currently, vacuum feeders require periodic shutdowns to clean the filters during operation. To ensure the filter's effectiveness, regular cleaning of the deposits not only places high demands on the filter's performance within a given period, but also inevitably affects work efficiency if cleaned in the short term. Furthermore, the disassembly, replacement, and maintenance processes are quite troublesome. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a vacuum feeder, which aims to improve the problems mentioned in the background art.

[0005] This application provides a vacuum feeder feeding component and a switching component.

[0006] The feeding assembly includes a fixed tube, a limiting ring, a filter, a top cover, a clamping component, a connecting component, and a fastener. The limiting ring is disposed inside the fixed tube, the filter is placed through the limiting ring, the clamping component is disposed inside the top cover and abuts against the filter, the connecting component is disposed between the fixed tube and the top cover, and the fastener is disposed on the outside of the connecting component.

[0007] The switching assembly includes a Y-shaped hopper, a feed pipe, a baffle, a solenoid valve, and a suction pipe. Two sets of the feeding assembly are provided on the top of the Y-shaped hopper. The feed pipe is connected to the feed pipe. The baffle is rotatably disposed inside the Y-shaped hopper. The solenoid valve is connected to the top of the top cover. The suction pipe is connected to the solenoid valve.

[0008] In one specific implementation, a positioning block is provided on the side of the filter, and a positioning groove is provided on the limiting ring, the positioning groove being adapted to the positioning block.

[0009] In the above implementation process, by setting the positioning groove and positioning block to be compatible, the positioning block can be inserted into the positioning groove when the filter is installed, which restricts the rotation of the filter and performs positioning.

[0010] In one specific implementation, the clamping element includes a threaded rod and a threaded cap, the threaded rod being fixedly connected to the top cover, the threaded cap being threadedly sleeved on the bottom end of the threaded rod, and the threaded cap abutting against the positioning block.

[0011] In the above implementation process, by setting a threaded rod and a threaded cap, the threaded cap can be rotated so that it can move along the axial direction of the threaded rod to adjust the distance.

[0012] In one specific implementation, the filter is located inside the fixed tube, and a handle is provided on the top of the filter.

[0013] In the above implementation process, a handle is provided to facilitate the handling of the filter for easy removal and replacement.

[0014] In one specific implementation, the docking component includes a groove shell and an insert plate. The groove shell is fixedly connected to the fixed pipe, and the insert plate is fixedly connected to the top cover. The insert plate is slidably inserted into the groove shell.

[0015] In the above implementation process, by setting up a slot shell and an insert plate, and using the insert plate to insert into the slot shell, not only can the top cover be positioned and installed, but the rotation of the top cover can also be restricted, thereby improving the stability of the installation.

[0016] In one specific implementation, a motor is provided on the outside of the Y-shaped hopper, and the baffle is driven to the output end of the motor.

[0017] In the above implementation process, a motor is set up to drive the baffle to rotate and adjust its position.

[0018] In one specific implementation, a limiting block is provided on the inner wall of the Y-shaped hopper, and the baffle abuts against the limiting block.

[0019] In the above implementation process, a limit block is set to limit the rotation range of the baffle.

[0020] In one specific implementation, the bottom of the Y-shaped hopper is conical, and a connecting pipe is provided at the bottom of the Y-shaped hopper.

[0021] Beneficial effects: This application provides a vacuum feeder that, by setting a fixed pipe, a limit ring, a filter, a top cover, a clamping component, a docking component, and a buckle, allows for convenient and quick disassembly and assembly of the filter, improving the efficiency of disassembly, assembly, maintenance, and replacement. Furthermore, by setting a Y-shaped hopper, a feed pipe, a baffle, a solenoid valve, and a suction pipe, the feeder components can be switched between.

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Please see Figures 1-5 This application provides a vacuum feeder feeding assembly 100 and a switching assembly 200.

[0031] Please see Figure 1 , 23. The feeding assembly 100 includes a fixed tube 110, a limiting ring 120, a filter 130, a top cover 140, a clamping member 150, a docking member 160, and a buckle 170. The limiting ring 120 is disposed inside the fixed tube 110, the filter 130 is placed inside the limiting ring 120, the clamping member 150 is disposed inside the top cover 140 and abuts against the filter 130, the docking member 160 is disposed between the fixed tube 110 and the top cover 140, and the buckle 170 is disposed outside the docking member 160.

[0032] The filter 130 has a positioning block 131 on its side and a positioning groove 121 on the limiting ring 120. The positioning groove 121 and the positioning block 131 are adapted to each other. By setting the positioning groove 121 and the positioning block 131 to be adapted to each other, the positioning block 131 can be inserted into the positioning groove 121 when the filter 130 is installed, thereby restricting the rotation of the filter 130 and positioning it.

[0033] Specifically, the clamping component 150 includes a threaded rod 151 and a threaded cap 152. The threaded rod 151 is fixedly connected to the top cover 140, and the threaded cap 152 is threadedly sleeved on the bottom end of the threaded rod 151. The threaded cap 152 abuts against the positioning block 131. By setting the threaded rod 151 and the threaded cap 152, the threaded cap 152 can be rotated, so that the threaded cap 152 can move axially along the threaded rod 151 to adjust the distance.

[0034] In this embodiment, the filter 130 is located inside the fixed tube 110, and a handle 132 is provided on the top of the filter 130. By providing the handle 132, it is convenient to hold the handle 132 to pick up and put down the filter 130, and it is convenient to replace the filter 130.

[0035] In this embodiment, the docking component 160 includes a groove shell 161 and an insert plate 162. The groove shell 161 is fixedly connected to the fixed pipe 110, and the insert plate 162 is fixedly connected to the top cover 140. The insert plate 162 is slidably inserted into the groove shell 161. By setting the groove shell 161 and the insert plate 162, and using the insert plate 162 to insert into the groove shell 161, not only can the top cover 140 be positioned and installed, but the rotation of the top cover 140 can also be restricted, thereby improving the stability of the installation.

[0036] Please see Figure 1 , 2 4 and 5, the switching component 200 includes a Y-shaped hopper 210, a feed pipe 220, a baffle 240, a solenoid valve 250, and a suction pipe 260. The top of the Y-shaped hopper 210 is provided with two sets of feeding components 100. The feed pipe 220 is connected to the feed pipe 220. The baffle 240 is rotatably installed inside the Y-shaped hopper 210. The solenoid valve 250 is connected to the top of the top cover 140. The suction pipe 260 is connected to the solenoid valve 250.

[0037] Among them, a motor 270 is provided on the outside of the Y-shaped hopper 210, and the baffle 240 is connected to the output end of the motor 270. The motor 270 is used to drive the baffle 240 to rotate and adjust its position.

[0038] Specifically, the inner wall of the Y-shaped hopper 210 is provided with a limiting block 211, and the baffle 240 abuts against the limiting block 211. By setting the limiting block 211, the rotation range of the baffle 240 is limited.

[0039] In one specific implementation, the bottom of the Y-shaped hopper 210 is conical, and a connecting pipe 212 is provided at the bottom of the Y-shaped hopper 210.

[0040] The working principle of this vacuum feeder is as follows: First, open the solenoid valve 250 on one set of feeding components 100 to draw air through the suction pipe 260 connected to the air pump. Then, start the motor 270 to rotate the baffle 240 to the other side, allowing the Y-shaped hopper 210 to connect to the fixed pipe 110 in one set of feeding components 100 for use. After a period of use, close the solenoid valve 250 of the currently used set and open the solenoid valve 250 on the other set of feeding components 100. Simultaneously, control the motor 270 to rotate the baffle 240 to block the unused fixed pipe 110. The temporarily unused fixed pipe 110 can be cleaned and filtered by the backflushing device. The device 130 can be used in this way, allowing two sets of feeding components 100 to be used alternately without stopping the machine. This not only ensures work efficiency and extends the service life of a single filter 130, but also makes it easier to disassemble, repair, and replace the filter 130. Simply open the latch 170, remove the top cover 140, and take it out by the handle 132 for replacement. During installation, simply insert the filter 130 into the limit ring 120, with the positioning block 131 correspondingly inserted into the positioning groove 121. Then, close the top cover 140, insert the insert plate 162 into the groove shell 161, lock the latch 170, and press the threaded cap 152 to tighten the filter 130. This improves the efficiency of disassembly, assembly, repair, and replacement.

[0041] It should be noted that the specific model and specifications of motor 270 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0042] The power supply and principle of motor 270 are clear to those skilled in the art and will not be described in detail here.

[0043] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
