Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a negative pressure adsorption pneumatic feeding device. Background Technology

[0002] A pneumatic feeding device is a device that uses compressed air as power to automatically convey and feed materials (such as powders, granules, and small lumps). Its core function is to replace manual handling and improve feeding efficiency and automation level.

[0003] An existing pneumatic feeding device, with publication number CN210619550U, uses an operable gate to control the size of the feed inlet, thereby adjusting the number of particles fed. An airflow generator further controls the air pressure and speed through the inlet, thus controlling the number of particles fed per unit time. However, current pneumatic feeding devices typically require operators to calculate pressure and flow rate before adjusting the gas velocity and flow rate via regulating valves. This increases the adjustment time required and makes the device inconvenient for operators. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a negative pressure adsorption pneumatic feeding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A negative pressure adsorption pneumatic feeding device includes a worktable, a housing, an air amplifier, an air inlet, a chute, a slider, a locking bolt, baffles, sealing plugs, a guide plate, a collection box, scales, a feed inlet, a rubber pad, a slide rail, and an opening. The upper surface of the worktable is machined with a chute, which is slidably connected to the slider. The surface of the slider is threadedly connected to the locking bolt, and the lower end of the locking bolt abuts against the chute. The slider is fixedly connected to two baffles, both of which are slidably connected to the housing and inserted into the housing. Multiple air inlets are machined on the two surfaces of the housing, each corresponding to a baffle. Two scales are mounted on the upper surface of the worktable, each scale contacting a baffle.

[0006] Preferably, the upper end of the workbench is fixedly connected to the box body, and the side wall of the box body is machined with a feed port.

[0007] Preferably, a rubber pad is adhered to the inner wall of the feed inlet, and the rubber pad is in contact with the sealing plug.

[0008] Preferably, an air amplifier is installed at one end of the housing.

[0009] Preferably, the upper surface of the workbench is fixedly connected to the guide plate, the lower inner surface of the guide plate is machined to be inclined, and the bottom end of the lower inner surface is the low side near the box body.

[0010] Preferably, the lower surface of the workbench has two slides, both of which are slidably connected to the collection box.

[0011] Preferably, the surface of the workbench has an opening, and the position of the collection box corresponds to the position of the opening.

[0012] The beneficial effects of this utility model are as follows: 1. With the set worktable, chute, slider, locking bolt, baffle, air inlet, and scale, when the adsorption speed of the material needs to be adjusted, the operator first loosens the locking bolt, then pushes the slider to slide in the chute. The slider drives the two baffles to move. The operator can know the distance the baffles have moved through the scale. When the two baffles move to the appropriate position in the box, the operator stops moving the slider and tightens the locking bolt to fix the position of the two baffles. In this way, the baffles can be easily moved to the appropriate position, so that the baffles block part of the air inlet. This changes the airflow rate, thereby adjusting the speed at which the material is adsorbed into the box. Moreover, the operator does not need to convert values ​​such as pressure and flow rate. They only need to observe the change in flow rate when the baffles move and know the distance the baffles have moved through the scale. This allows for different levels of adjustment of the gas flow rate of the air amplifier, making it convenient for the operator to use this pneumatic feeding device. 2. With the help of the guide plate, worktable, and collection box, when the material is placed on the guide plate and moves to the inlet of the box, the lower end of the guide plate is inclined and the lower end is located near the side of the box. Therefore, the material will move towards the inlet of the box surface as it slides down. This allows the inlet to absorb more material. When the material passes the inlet and is not absorbed, it will slide along the guide plate to the opening on the worktable and fall into the collection box below. When the collection box has collected a lot of material and the guide plate no longer has any material falling, the operator can remove the collection box from the slide on the worktable and recycle the material in the collection box. This improves the working efficiency of the feeding device. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1, referring to Figures 1 to 5A negative pressure adsorption pneumatic feeding device includes a workbench 1, a housing 2, an air amplifier 3, an air inlet 4, a chute 5, a slider 6, a locking bolt 7, a baffle 8, a sealing plug 9, a guide plate 10, a collection box 11, a scale 12, a feed inlet 13, a rubber pad 14, a slide rail 15, and an opening 16. The upper surface of the workbench 1 is machined with a chute 5, which is slidably connected to the slider 6. The slider 6 slides within the chute 5. The surface of the slider 6 is threadedly connected to the locking bolt 7, which fixes the position of the slider 6. The lower end of the locking bolt 7 abuts against the chute 5. The slider 6 is fixedly connected to two baffles 8, and the slider 6 drives the baffles. The two baffles 8 are slidably connected to the housing 2 and slide inside the housing 2. Both baffles 8 are inserted into the housing 2. Multiple air inlets 4 are machined on the two surfaces of the housing 2. The air inlets 4 allow gas to enter the housing 2. The position of each air inlet 4 corresponds to the position of the corresponding baffle 8. The baffle 8 can partially block the position of the air inlet 4, thereby controlling the gas flow. Two scales 12 are installed on the upper surface of the workbench 1. The scales 12 make it easy for the operator to know the moving distance of the baffle 8, thereby better controlling the gas flow. Each scale 12 is in contact with the baffle 8. When the adsorption speed of the material needs to be adjusted, the operator first loosens the locking bolt 7, then pushes the slider 6 to slide in the groove 5. The slider 6 drives the two baffles 8 to move. The operator can use the scale 12 to know the distance the baffles 8 have moved. When the two baffles 8 have moved to the appropriate position in the box 2, the operator stops moving the slider 6 and tightens the locking bolt 7 to fix the position of the two baffles 8. In this way, the baffles 8 can be easily moved to the appropriate position, so that the baffles 8 block part of the air inlet 4. This changes the airflow rate, thereby adjusting the speed at which the material is adsorbed into the box 2. Moreover, the operator does not need to convert values ​​such as pressure and flow rate. They only need to observe the change in flow rate when the baffles 8 move and know the distance the baffles 8 have moved through the scale 12. This allows for different levels of adjustment of the gas flow rate of the air amplifier 3, making it convenient for the operator to use the pneumatic feeding device.

[0017] In this embodiment, the upper end of the workbench 1 is fixedly connected to the housing 2, and the housing 2 is installed on the workbench 1. A feed inlet 13 is machined on the side wall of the housing 2, allowing material to enter the housing 2. A rubber gasket 14 is adhered to the inner wall of the feed inlet 13, allowing the sealing plug 9 to be inserted into the housing 2. The rubber gasket 14 contacts the sealing plug 9. An air amplifier 3 is installed at one end of the housing 2. The model of the air amplifier 3 is selected according to actual needs, choosing one that meets the operational requirements. The upper surface of the workbench 1 is fixedly connected to the guide plate 10, which is installed on the workbench 1. The lower inner surface of the guide plate 10 is machined into an inclined shape. The workbench 1 is slanted, and the bottom of the lower surface of the inner surface is lower on the side near the box 2. This allows the material to move towards the side near the feed inlet 13 when it moves on the guide plate 10, making it easier for the feed inlet 13 to absorb and feed more material. The lower surface of the workbench 1 has two slides 15, both of which are slidably connected to the collection box 11. The collection box 11 can slide out from under the workbench 1. The surface of the workbench 1 has an opening 16, which allows the material to fall directly into the collection box 11 without manual collection. The position of the collection box 11 corresponds to the position of the opening 16 to prevent the material from falling to other positions.

[0018] The working principle of this embodiment is as follows: In use, first connect the external power supply to the air amplifier 3 to start it. The air amplifier 3 compresses air, which is then ejected at high speed through a special internal annular nozzle, creating a low-pressure zone around the nozzle. This low-pressure zone will "absorb" air. The ambient air mixes with the input compressed air, and finally outputs a total airflow several times the input volume from the other end, thus enabling negative pressure adsorption feeding of materials. The operator removes the sealing plug 9 from the box 2, and then places the material on the guide plate 10. When it moves to the feed inlet 13 of the box 2, because the lower end of the guide plate 10 is inclined and the lower end is located closer to the side of the box 2, the material will move closer to the feed inlet 13 on the surface of the box 2 as it slides down. This allows the air amplifier 3 to adsorb more material through the feed inlet 13. When the material passes through the feed inlet 13 and is not adsorbed, the material will slide along the guide plate 10 to the opening 16 on the workbench 1, and fall into the collection box 11 below through the opening 16. When the collection box 11 has collected a large amount of material and the guide plate 10 no longer receives material, the material is collected. When the material is collected, the operator can remove the collection box 11 from the slide rail 15 on the workbench 1 to collect the material in the collection box 11. When it is necessary to adjust the adsorption speed of the material, the operator first loosens the locking bolt 7, and then pushes the slider 6 to slide in the slide groove 5. The slider 6 drives the two baffles 8 to move. The operator can use the scale 12 to know the distance the baffles 8 have moved. When the two baffles 8 have moved to the appropriate position in the box 2, the operator stops moving the slider 6 and tightens the locking bolt 7 to fix the position of the two baffles 8. In this way, the baffles 8 can be easily moved to the appropriate position, so that the baffles 8 block part of the air inlet 4. This changes the airflow and thus adjusts the speed at which the material is adsorbed into the box 2 without stopping the machine. This makes it convenient for the operator to use the negative pressure adsorption pneumatic feeding device.
