Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum feeding machine technology, specifically to a vacuum feeding machine for conveying powder particles. Background Technology
[0002] A vacuum conveyor is a dust-free, closed-loop pipeline transport device that uses vacuum suction to transport granular and powdered materials. It utilizes the pressure difference between the vacuum and the ambient space to create gas flow within the pipeline, thereby moving the granular or powdered materials and completing the conveying process. Through continuous improvement and refinement, vacuum conveyors are now widely used in various light and heavy industrial sectors, including chemical, pharmaceutical, food, metallurgy, building materials, and agricultural products.
[0003] For example, Chinese patent CN217675556U discloses a vacuum feeder for powder production, relating to the field of powder production technology. It includes a machine body, with a feed pipe connected to one side and a mixing tank at one end. A connecting hose is connected to one side of the mixing tank, and a suction pipe is installed at one end of the connecting hose. This vacuum feeder, when powder needs to be suctioned, allows personnel to activate an electric telescopic rod, which pushes the suction pipe, moving it through the connecting hose to adjust its position and allow it to suction the powder. The electric telescopic rod also supports the suction pipe, eliminating the need for personnel to handle it, saving time. To remove the suction pipe, personnel can remove the fixing bolts from the fixing block, then remove the second fixing ring from the first fixing ring, and finally remove the suction pipe from the fixing ring, completing the disassembly of the suction pipe.
[0004] However, the vacuum feeder for powder production provided by the above patent has the following problems: (1) The height of the existing vacuum feeder for powder production is fixed and the machine body does not have the function of height adjustment. This also leads to the problem that the vacuum feeder cannot adjust its own height according to the height of the material conveying to meet the feeding requirements when working, which indirectly reduces the practicality of the vacuum feeder and makes it difficult to promote; (2) The existing vacuum feeder for powder production will generate high-frequency slight vibration during the working process. However, since the vibration damping effect of the vacuum feeder itself is not particularly ideal, the vacuum feeder is prone to loosening and falling off of its internal parts when facing high-frequency slight vibration for a long time, which indirectly increases the maintenance cost and cannot meet the usage requirements. Utility Model Content
[0005] The purpose of this invention is to address the problems of existing vacuum feeders for powder production, such as the inability to adjust the height and the susceptibility of parts to loosening and falling off due to high-frequency slight vibrations during use, resulting in high maintenance costs. This invention provides a vacuum feeder for powder conveying, which solves the above problems.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0007] This utility model provides a vacuum feeder for conveying powder and granules, which includes the following structural configuration:
[0008] A base plate having opposing first and second surfaces;
[0009] A height adjustment mechanism is fixedly mounted on the first surface of the base plate;
[0010] The vacuum feeder body is mounted on the height adjustment mechanism and its height is adjusted by the height adjustment mechanism.
[0011] And several shock-absorbing structures are disposed on the second surface of the base plate to provide shock absorption for the vacuum feeder.
[0012] Specifically, this invention relates to a vacuum conveyor for powder and granule conveying. By incorporating a height adjustment mechanism, the height of the vacuum conveyor body can be adjusted, thus solving the problem that existing vacuum conveyors have a fixed height and lack height adjustment functionality, preventing them from adjusting their height to meet material feeding requirements during operation. Furthermore, this invention utilizes several shock-absorbing structures to address the issue of insufficient shock absorption in existing vacuum conveyors, which can lead to loosening and dislodging of internal components under prolonged exposure to high-frequency, slight vibrations, thereby avoiding increased maintenance costs.
[0013] Furthermore, a vacuum feeder for conveying powder particles includes a height adjustment mechanism comprising:
[0014] A height adjustment frame is vertically disposed on the first surface. The interior of the height adjustment frame is provided with a first mounting groove along the height adjustment direction, and the side of the height adjustment frame is provided with a height adjustment groove communicating with the first mounting groove along the height adjustment direction.
[0015] A drive motor is disposed in the first mounting slot;
[0016] A fixing block is disposed in the first mounting slot, and the fixing block and the drive motor are disposed at opposite ends of the first mounting slot;
[0017] A lead screw is disposed therein along the height adjustment direction of the first mounting groove, with one end of the lead screw connected to the drive motor and the other end rotatably connected to the fixed block;
[0018] A height adjustment seat is threadedly connected to the lead screw to form a lead screw structure (the height adjustment seat and the lead screw cooperate to form a lead screw structure);
[0019] The vacuum feeder body is mounted on the height adjustment plate, which is connected to the height adjustment seat and is driven by it to move up and down.
[0020] Furthermore, a vacuum feeder for conveying powder particles includes a height adjustment mechanism that further comprises a connecting block, one end of which is connected to the height adjustment seat, and the other end of which passes through the height adjustment groove and is connected to the height adjustment plate (i.e., the height adjustment plate is connected to the height adjustment seat through the connecting block).
[0021] Furthermore, a vacuum feeder for conveying powder particles: a second mounting groove is provided on the height adjustment plate, and the body of the vacuum feeder is disposed in the second mounting groove.
[0022] This design allows the vacuum feeder body to be mounted more stably on the height adjustment plate, thereby improving the vibration resistance of the vacuum feeder body.
[0023] Furthermore, a vacuum feeder for conveying powder particles includes the following shock-absorbing structure:
[0024] A shock-absorbing seat is fixedly mounted on the second surface of the base plate, and the shock-absorbing seat is provided with a first shock-absorbing groove with an opening facing away from the second surface.
[0025] A shock absorber block is movably disposed in the first shock absorber groove, and the shock absorber block is provided with a plurality of second shock absorber grooves;
[0026] Several elastic balls are respectively disposed in the second shock-absorbing groove;
[0027] Several limiting blocks are respectively movably disposed in the second shock-absorbing groove and located at the top of the elastic ball;
[0028] Several damping rods, one end of which extends into the second damping groove and is fixedly connected to the limiting block, and the other end is used to abut against the damping seat;
[0029] And several damping springs, which are disposed in the first damping groove and one end is connected to the damping block, and the other end is used to abut against the damping seat.
[0030] Furthermore, in a vacuum feeder for conveying powder particles, the shock-absorbing spring is sleeved on the damping rod. The shock-absorbing spring is mounted on the shock-absorbing block by welding one end, and the dimensions of the shock-absorbing spring are adapted to the dimensions of the damping rod.
[0031] Furthermore, a vacuum feeder for conveying powder particles includes a shock-absorbing structure that further comprises a buffer elastic block; the buffer elastic block is located in the first shock-absorbing groove and is disposed between the shock-absorbing seat and the shock-absorbing block.
[0032] Furthermore, in a vacuum feeder for conveying powder particles, the buffer elastic block is made of rubber and is connected to the shock-absorbing block. Specifically, the buffer elastic block is installed on the shock-absorbing block by adhesive bonding.
[0033] Furthermore, a vacuum feeder for conveying powder particles: the elastic balls are arranged in an elliptical structure, and a plurality of the elastic balls are arranged in a rectangular array at the bottom of the second shock-absorbing groove.
[0034] The beneficial effects of this utility model are:
[0035] (1) The vacuum feeder for powder conveying designed in this utility model has a height adjustment mechanism. When the vacuum feeder needs to adjust the height, the drive motor can be started to drive the lead screw to rotate, thereby driving the height adjustment seat to rise and fall. The height adjustment seat drives the height adjustment plate and the vacuum feeder body set on it to rise and fall along the height adjustment groove, thereby adjusting the height of the vacuum feeder body to meet the feeding height requirements. This structural design of this utility model enables the vacuum feeder to have a height adjustment function, solving the problem that the vacuum feeder cannot adjust its own height according to the height of the material conveying to meet the feeding requirements when it is working. This indirectly improves the practicality of the vacuum feeder and facilitates its widespread use.
[0036] (2) The vacuum feeder for conveying powder and granules designed in this utility model can weaken and reduce the impact force and amplitude of high-frequency slight vibration during operation by setting a shock-absorbing structure, thereby improving the shock absorption effect of the vacuum feeder itself. This structural design avoids the problem that the vacuum feeder is prone to loosening and falling off its internal parts when it is exposed to high-frequency slight vibration for a long time due to the less-than-ideal shock absorption effect of the vacuum feeder itself, thereby indirectly reducing the maintenance cost and meeting the usage requirements.

[0045] Example 1
[0046] like Figures 1-4 As shown, this embodiment 1 provides a vacuum feeder for conveying powder particles, which includes the following specific structural configuration:
[0047] The base plate 1 has opposing first surfaces 11 and second surfaces 12;
[0048] The height adjustment mechanism 2 includes a height adjustment frame 21, a drive motor 22, a fixing block 23, a lead screw 24, a height adjustment seat 25, a connecting block 26, and a height adjustment plate 27. The height adjustment frame 21 is vertically disposed on the first surface 11, and a first mounting groove 211 is provided inside the height adjustment frame 21 along the height adjustment direction. A height adjustment groove 212 communicating with the first mounting groove 211 is provided on the side of the height adjustment frame 21 along the height adjustment direction. The drive motor 22 (model 60ST-M01330) is disposed in the first mounting groove 211. The fixing block 23 is disposed in the first mounting groove 211, and the fixing block 23 is separate from the drive motor 22. The height adjustment plate 27 is located at both ends of the first mounting groove 211; the lead screw 24 is disposed in the first mounting groove 211 along the height adjustment direction, with one end of the lead screw 24 connected to the drive motor 22 and the other end rotatably connected to the fixing block 23; the height adjustment seat 25 is threadedly connected to the lead screw 24 (the height adjustment seat 25 and the lead screw 24 form a lead screw structure); one end of the connecting block 26 is connected to the height adjustment seat 25, and the other end passes through the height adjustment groove 212 and is connected to the height adjustment plate 27; the height adjustment plate 27 is connected to the height adjustment seat 25 through the connecting block 26 and is driven by it to rise and fall, and the height adjustment plate 27 is also provided with a second mounting groove 271;
[0049] The vacuum feeder body 3 is installed in the second mounting slot 271 on the height adjustment plate 27, and the height of the vacuum feeder body 3 is adjusted by the height adjustment mechanism 2.
[0050] The system includes several damping structures 4, comprising a damping seat 41, a damping block 42, several elastic balls 43, several limiting blocks 44, several damping rods 45, several damping springs 46, and a buffer elastic block 47; wherein, the damping seat 41 is fixedly disposed on the second surface 12, and the damping seat 41 is provided with a first damping groove 411 with an opening facing away from the second surface 12; the damping block 42 is movably disposed in the first damping groove 411, and the damping block 42 is provided with several second damping grooves 421; the elastic balls 43 are generally elliptical and are arranged in a rectangular array at the bottom of the second damping grooves 421; the limiting blocks 44 are movably disposed in the second damping grooves 421 and located at the top of the elastic balls 43; the damping rods 45, 46, and 47 are respectively located at the bottom of the second damping grooves 421; the damping blocks 45 are respectively located at the top of the second damping grooves 421; the damping rods 46, 47, and 48 are respectively located at the bottom of the second damping grooves 421; the damping blocks 46 are respectively located at the bottom of the second damping grooves 421; the damping blocks 47 ... One end of the 5 extends into the second damping groove 421 and is fixedly connected to the limiting block 44, while the other end is used to abut against the damping seat 41; the damping spring 46 is disposed in the first damping groove 411 and one end is connected to the damping block 42 by welding, while the other end is used to abut against the damping seat 41, and the damping spring 46 is sleeved on the damping rod 45; the buffer elastic block 47 is located in the first damping groove 411 and is disposed between the damping seat 41 and the damping block 42. The buffer elastic block 47 is made of rubber and is connected to the damping block 42 by adhesive bonding. Through the elasticity of the buffer elastic block 47, the impact force and vibration amplitude generated by high-frequency slight vibration can be further reduced, thereby improving the damping effect of the vacuum feeder itself.
[0051] Specifically, in embodiment 1, the top end of the lead screw 24 is fixedly connected to the drive motor 22, and the bottom end of the lead screw 24 passes through the height adjustment seat 25 and is rotatably connected to the fixed block 23. There are two sets of lead screws 24, which are arranged correspondingly to each other in the middle of the base plate 1, which facilitates the installation and support of the lead screws 24 and improves the stability of the lead screws 24 when rotating. The connecting block 26 is fixedly connected to the height adjustment seat 25. The connecting block 26 can move up and down in the height adjustment groove 212, which facilitates the vacuum feeder body 3 to move vertically along the length direction of the height adjustment groove 212 by following the rotation direction of the lead screw 24 through the height adjustment seat 25, thereby realizing the adjustment of the height of the vacuum feeder to meet the feeding height requirements.
[0052] Meanwhile, in this embodiment 1, the elastic balls 43 are arranged in an elliptical structure, and the number of elastic balls 43 is set to several groups. The elastic balls 43 are arranged in a rectangular array, which facilitates the weakening and reduction of the impact force and vibration amplitude generated by high-frequency slight vibration through the elasticity of the elastic balls 43, thereby improving the vibration reduction effect of the vacuum feeder itself; the damping rod 45 is fixedly connected to the limiting block 44. The size of the limiting block 44 is adapted to the size of the second damping groove 421, which facilitates the limiting of the damping rod 45 and prevents it from falling out of the second damping groove 421. The damping spring 46 is welded onto the damping block 42. The size of the damping spring 46 is matched with the size of the damping rod 45, so that the damping rod 45 and the damping spring 46 can cooperate to weaken and reduce the impact force and amplitude of high-frequency slight vibration, thereby improving the damping effect of the vacuum feeder itself. The buffer elastic block 47 is made of rubber and is installed on the damping block 42 by adhesive connection, which facilitates the installation and fixation of the buffer elastic block 47 and improves the stability of the buffer elastic block 47.
[0053] The working principle and usage process of the vacuum feeder for powder conveying in this embodiment 1 are as follows: When the height needs to be adjusted, the drive motor 22 in the height adjustment mechanism 2 drives the lead screw 24 to rotate, causing the height adjustment seat 25 to move up and down, thereby driving the height adjustment plate 27 to move up and down, which in turn drives the vacuum feeder body 3 on the height adjustment plate 27 to move up and down, thus realizing the height adjustment function of the vacuum feeder body 3 to meet the needs of different feeding heights. This structural design in Example 1 enables the vacuum feeder to have height adjustment capabilities, avoiding the problem that the vacuum feeder cannot adjust its height to meet the feeding requirements according to the material conveying height during operation. When faced with high-frequency slight vibrations generated during operation, the damping seat 41 in the damping structure 4 presses the damping spring 46 on the outer surface of the damping rod 45 and the buffer elastic block 47 on the damping block 42, thereby driving the limiting block 44 connected to the damping rod 45 to press the elastic ball 43 in the second damping groove 421. At the same time, the elastic force of the elastic ball 43, the damping spring 46 and the buffer elastic block 47 reacts to the damping seat 41, thereby weakening and reducing the impact force and vibration amplitude generated by high-frequency slight vibrations, thus improving the damping effect of the vacuum feeder itself. This design of the damping structure 4 avoids the problem that the vacuum feeder's internal components are prone to loosening and falling off due to the vacuum feeder's own less-than-ideal damping effect when facing high-frequency slight vibrations for a long time.
[0054] In summary, the vacuum conveyor for powder conveying designed in this utility model, through the cooperation of the base plate 1, height adjustment frame 21, drive motor 22, fixing block 23, lead screw 24, height adjustment seat 25, connecting block 26, height adjustment plate 27, and height adjustment groove 212, enables the vacuum conveyor body 3 to have a height adjustment function, avoiding the problem that the vacuum conveyor cannot adjust its own height to meet the feeding requirements according to the height of the material being conveyed during operation. At the same time, this utility model improves the vibration reduction effect of the vacuum conveyor itself through the cooperation of the vibration damping seat, vibration damping block, elastic ball, limit block, damping rod, vibration damping spring, and buffer elastic block in the vibration damping structure, avoiding the problem of loosening and falling off of internal components when the vacuum conveyor is exposed to high-frequency slight vibration for a long time.
[0055] The above-described preferred embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of this utility model. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
