Description

Technical Field

[0001] This utility model relates to the technical field of magnetic tile manufacturing, and in particular to an automatic powder feeding device. Background Technology

[0002] In modern industrial production, powdered materials are important raw materials, widely used in many fields such as chemicals, building materials, and food. Currently, for ease of transportation and storage, powders are usually transported in bags. However, in actual factory production processes, when bagged powders need to be added to mixers for mixing, the traditional manual operation method is still largely relied upon.

[0003] However, existing powder feeding methods have the following shortcomings in practical application: workers need to manually move bags of powder from the storage area to the mixer and then manually open the bags to complete the feeding. From a cost perspective, this frequent manual handling and feeding requires a large labor input, resulting in high labor costs, especially given the current rising labor costs, which are putting increasing pressure on enterprises' production and operating costs. In terms of efficiency, manual operation is far less fast and continuous than automated equipment. Not only is each feeding time longer, but workers are also prone to fatigue after long hours of work, leading to a further decline in work efficiency. This makes it difficult to meet the needs of large-scale, continuous production, seriously affecting production progress and capacity improvement. In view of this, an automatic powder feeding device is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic powder feeding device for automatically feeding bagged powder, thereby improving work efficiency and reducing labor costs.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An automatic powder feeding device is used to feed bagged powder located on a conveyor belt into a mixing tank, comprising:

[0007] Frame; and

[0008] The feeding assembly includes a cutter, a central column, a first drive unit, a second drive unit, and several hooks. The first drive unit is mounted on the frame and located above the conveyor belt. The second drive unit is mounted on the frame. The central column is rotatably mounted on the frame and connected to the output shaft of the second drive unit. Each hook slides vertically on the central column and is equidistantly distributed. The cutter is adjustablely slidable on the frame and located above the mixing tank. The cutter is used to cut open bagged powder. When the second drive unit drives the central column to rotate relative to the frame, each hook circulates through the output shaft of the first drive unit and the cutter. When a hook is connected to the output shaft of the first drive unit, the first drive unit drives the hook to hook the bagged powder from the conveyor belt.

[0009] Optionally, the hook claw includes a stud, a slide block, and a toothed block. The stud is rotatably mounted on the central column, the slide block is slidably mounted on the central column, and the slide block is screwed to the stud. The toothed block is disposed on one end of the stud and is used to engage with the first driving member.

[0010] Optionally, the hook component further includes a claw rod and a pull rod, one end of the claw rod and the pull rod being rotatably connected to the slide block, and the other end of the pull rod being slidably engaged with the claw rod.

[0011] Optionally, the claw bar has a waist-shaped hole, and the pull rod has a protrusion that slides within the waist-shaped hole.

[0012] Optionally, the hook and claw component further includes a plurality of cone blocks, each of which is disposed on the claw bar.

[0013] Optionally, the feeding assembly further includes a support ring, which is disposed on the frame, and a locking block is provided on the slide block, which is slidably engaged with the support ring.

[0014] Optionally, the support ring includes a triangular seat and a retaining ring. The triangular seat is disposed on the frame, and the retaining ring is disposed on the triangular seat. The retaining block is slidably engaged with the retaining ring.

[0015] Optionally, the retaining ring is a ring structure with an opening.

[0016] Optionally, the card block has a slot, the width of which is greater than the thickness of the retaining ring.

[0017] Optionally, the retaining ring is provided with a vibration groove.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] This utility model discloses an automatic powder feeding device. A second driving component rotates a central column, causing each hook sliding on the central column to connect to a first driving component in turn. This allows the first driving component to move one hook upwards to hook up bagged powder, moving the powder above the mixing tank and close to the cutter to puncture the bag and allow the powder to fall into the mixing tank. Simultaneously, the central column causes the hook to disengage from the support ring, allowing it to slide downwards so that the waste hopper can collect discarded bags, facilitating cyclical operation. This achieves automatic, continuous, and cyclical feeding, improving work efficiency and reducing labor costs. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0040] like Figures 1 to 8 As shown, in one embodiment, an automatic powder feeding device 1 is used to feed bagged powder located on a conveyor belt 10 into a mixing tank 11. It includes a frame 20 and a feeding assembly 30. The feeding assembly 30 includes a cutter 31, a central column 32, a first driving member 33, a second driving member 34, and several hook members 35. The first driving member 33 is mounted on the frame 20 and is located above the conveyor belt 10. The second driving member 34 is mounted on the frame 20. The central column 32 is rotatably mounted on the frame 20 and is connected to the output shaft of the second driving member 34. Next, each hook 35 slides vertically on the central column 32, and each hook 35 is equidistantly distributed. The cutter 31 slides adjustablely on the frame 20, and the cutter 31 is located above the mixing tank 11. The cutter 31 is used to cut open the bagged powder. When the second drive member 34 drives the central column 32 to rotate relative to the frame 20, each hook 35 circulates through the output shaft of the first drive member 33 and the cutter 31. When the hook 35 is connected to the output shaft of the first drive member 33, the first drive member 33 drives the hook 35 to hook the bagged powder from the conveyor belt 10.

[0041] It should be noted that the conveyor belt 10 and the mixing tank 11 are located on both sides of the frame 20, the first drive unit 33 is located above the frame 20, the second drive unit 34 is located below the frame 20, and the central column 32 is rotatably mounted on the frame 20, with the bottom end of the central column 32 connected to the output shaft of the second drive unit 34. For example, the bottom end of the central column 32 can be connected to the output shaft of the second drive unit 34 via a belt, or the bottom end of the central column 32 can be connected to the output shaft of the second drive unit 34 via a chain, so that the second drive unit 34 drives the central column 32 to rotate relative to the frame 20. Furthermore, when the second drive member 34 drives the central column 32 to rotate relative to the frame 20, each hook member 35 sequentially passes through the first drive member 33 and the cutter 31. Specifically, since each hook member 35 is equidistantly distributed along the circumference of the central column 32, when the central column 32 rotates, each hook member 35 rotates around the axis of the central column 32. The first drive member 33 and the cutter 31 are located on both sides of the central column 32, thus allowing the hook members 35 to pass through the first drive member 33 and the cutter 31 in turn. Furthermore, when any hook member 35 is connected to the first drive member 33, the first drive member 33 drives the hook member 35 to move up and down relative to the central column 32. Specifically, the bagged powder is laid flat on the conveyor belt 10. When the conveyor belt 10 moves the bagged powder close to the central column 32, one end of the bagged powder will extend from one end of the conveyor belt 10. Thus, when the hook 35 slides upward, it can hook the bag and lift the bagged powder. Further, after the first drive member 33 drives the hook 35 to hook the bagged powder, the second drive member 34 continues to drive the central column 32 to rotate so that the bagged powder rotates closer to the mixing tank 11 and is located above the mixing tank 11. The cutter 31 is also located above the mixing tank 11. Thus, when the bagged powder rotates closer to the mixing tank 11, the cutter 31 cuts the bag, allowing the powder to fall into the mixing tank 11.

[0042] like Figures 3 to 4 , Figures 6 to 7 As shown, in one embodiment, the hook claw 35 includes a stud 350, a slide 351, and a toothed block 352. The stud 350 is rotatably mounted on the central column 32, the slide 351 is slidably mounted on the central column 32, and the slide 351 is screwed to the stud 350. The toothed block 352 is mounted on one end of the stud 350 and is used to engage with the first driving member 33.

[0043] It should be noted that the central column 32 has several sliding grooves 320, each groove 320 being opened along the axial direction of the central column 32, and each groove 320 being equidistantly distributed circumferentially around the axis of the central column 32. Each hook member 35 slides correspondingly within each groove 320. The stud 350 is rotatably mounted on the central column 32, and the stud 350 is located within the groove 320, with one end of the stud 350 extending from the end of the central column 32 closest to the first driving member 33. The toothed block 352 is located at the end of the stud 350 closest to the first driving member 33. The slide block 351 slides within the groove 320, and the slide block 351 is screwed to the stud 350. Furthermore, a gear is provided on the output shaft of the first driving member 33. When the hook 35 is connected to the output shaft of the first driving member 33, the toothed block 352 meshes with the gear. In this way, the first driving member 33 can drive the stud 350 to rotate through the toothed block 352. When the stud 350 rotates, it can drive the slide 351 to slide up and down relative to the central column 32. Both the first driving member 33 and the second driving member 34 are motor structures.

[0044] like Figures 3 to 4 , Figures 6 to 7 , Figures 13 to 14 As shown, in one embodiment, the hook claw 35 further includes a claw bar 354 and a pull rod 355. One end of the claw bar 354 and the pull rod 355 are rotatably connected to the slide block 351, and the other end of the pull rod 355 is slidably engaged with the claw bar 354.

[0045] It should be noted that one end of both the claw rod 354 and the pull rod 355 is rotatably connected to the side of the slide block 351 away from the slide groove 320. The claw rod 354 is located at the end of the slide block 351 away from the first driving member 33, and the pull rod 355 is located at the end of the slide block 351 close to the first driving member 33. There is a gap between the claw rod 354 and the pull rod 355. Furthermore, the claw rod 354 has an oblong hole 3540, with both ends of the oblong hole 3540 facing the two ends of the claw rod 354. A protrusion is provided on the end of the pull rod 355 away from the slide block 351. The diameter of the protrusion matches the diameter of the oblong hole 3540, allowing the protrusion to slide within the oblong hole 3540. Specifically, since the pull rod 355 is located above the claw rod 354, when the protrusion slides to the end of the oblong hole 3540 near the slide block 351, the end of the claw rod 354 away from the slide block 351 extends relative to the slide block 351, and an obtuse angle is formed between the claw rod 354 and the slide block 351. When the protrusion slides to the end of the oblong hole 3540 away from the slide block 351, the section of the claw rod 354 away from the slide block 351 retracts relative to the slide block 351, and an acute angle is formed between the claw rod 354 and the slide block 351. Thus, when the stud 350 drives the slide 351 to slide downwards and approach the conveyor belt 10, the side of the claw bar 354 away from the pull rod 355 comes into contact with the bagged powder on the conveyor belt 10, thereby causing the end of the claw bar 354 away from the slide 351 to rotate and approach the central column 32, so that the slide 351 drives the claw bar 354 to slide over the bagged powder. When the slide 351 drives the claw bar 354 to slide to the bottom surface of the bagged powder, under the action of gravity, the end of the claw bar 354 away from the slide 351 will swing and extend to approach the bottom surface of the bagged powder. At this time, when the first driving member 33 drives the slide 351 to slide upwards, the end of the claw bar 354 away from the slide 351 hooks the bagged powder upwards.

[0046] like Figures 13 to 14 As shown, in one embodiment, the hook claw 35 further includes a plurality of cone blocks 356, each cone block 356 being disposed on the claw bar 354.

[0047] It should be noted that the claw bar 354 has a T-shaped structure, and the end of the claw bar 354 away from the slide block 351 has an inclined surface, which is located on the side of the claw bar 354 away from the slide block 351. Each cone 356 is spaced apart on the inclined surface. Thus, when the claw bar 354 is away from the central column 32 relative to the slide block 351 and is located on the bottom surface of the bagged powder, each cone 356 is tilted towards the bagged powder, so that when the slide block 351 drives the claw bar 354 to slide upward, each cone 356 can hook the bagged powder.

[0048] like Figure 1 , Figures 4 to 11As shown, in one embodiment, the feeding assembly 30 further includes a support ring 36, which is disposed on the frame 20. A locking block 353 is disposed on the slide block 351, and the locking block 353 is slidably engaged with the support ring 36.

[0049] It should be noted that a support platform 21 is provided on the frame 20, located on the end face of one end of the frame 20. The support platform 21 tends to be U-shaped, creating a gap between the support platform 21 and the frame 20. A bracket ring 36 is provided on the frame 20, and the bracket ring 36 is located within the gap between the support platform 21 and the frame 20. Furthermore, a circular hole is provided on the frame 20, located on the end face of the frame 20 near the support platform 21, and the bracket ring 36 is coaxially aligned with the circular hole. Furthermore, a first driving member 33 is provided on the support platform 21, and the output shaft of the first driving member 33 extends into the gap between the support platform 21 and the frame 20. One end of the central column 32 passes through the circular hole and extends into the gap between the end faces of the frame 20 and the support platform 21. Thus, when the central column 32 drives each hook member 35 to rotate relative to the frame 20, each hook member 35 can pass through the output shaft of the first driving member 33 in turn. Furthermore, when any one of the hook claws 35 is connected to the first driving member 33, the first driving member 33 drives the slide block 351 to slide upward relative to the central column 32 through the stud 350. The frame 20 has a through hole. When the sliding groove 320 of the slide block 351 is close to the end of the round hole, the end of the locking block 353 away from the slide block 351 passes through the through hole and extends into the gap between the support platform 21 and the frame 20 to engage with the bracket ring 36. Specifically, when the first driving member 33 drives the slide block 351 to slide upward via the stud 350, thereby causing the claw bar 354 to hook the bagged powder and lift it upward to the end of the central column 32 near the first driving member 33, the locking block 353 approaches the support ring 36. At this time, when the second driving member 34 continues to drive the central column 32 to rotate, the central column 32 will drive the locking block 353 to slide and engage along the circumference of the support ring 36, thereby causing the hook claw 35 to move the hooked bagged powder from the side of the frame 20 near the conveyor belt 10 to the side of the frame 20 near the mixing tank 11, and position it above the mixing tank 11. Further, the cutter 31 is located above the mixing tank 11. When the central column 32 drives the hook claw 35 that hooks the bagged powder to pass above the mixing tank 11, the cutter 31 horizontally slices across the bagged powder, thereby causing the cutter 31 to cut open the bag of powder and let the powder fall into the mixing tank 11.

[0050] like Figures 9 to 10 As shown, in one embodiment, the support ring 36 includes a triangular base 360 ​​and a retaining ring 361. The triangular base 360 ​​is disposed on the frame 20, and the retaining ring 361 is disposed on the triangular base 360. The retaining block 353 is slidably engaged with the retaining ring 361.

[0051] It should be further noted that the triangular base 360 ​​is mounted on the frame 20 and located within the gap between the support platform 21 and the frame 20. The retaining ring 361 is mounted on the triangular base 360, and the retaining ring 361 and the circular hole are coaxially aligned. Furthermore, the retaining ring 361 is an annular structure with an opening, and the retaining block 353 has a retaining slot 3530 located on the side of the retaining block 353 closest to the retaining ring 361, with the width of the retaining slot 3530 greater than the thickness of the retaining ring 361. When the first driving member 33 drives the locking block 353 to extend from the frame 20 and approach the retaining ring 361, the locking block 353 is positioned at the locking slot 3530 of the retaining ring 361, thus aligning the locking slot 3530 with the opening. Meanwhile, when the central column 32 drives the hook pawl 35 to rotate and disengage from the output shaft of the first driving member 33, the locking slot 3530 engages circumferentially with the retaining ring 361. This allows the hook pawl 35 to hook the bagged powder and rotate it circumferentially along the retaining ring 361 to the top of the mixing tank 11. Furthermore, the arc length of the opening is greater than the angle between two adjacent sliding grooves 320, and one end of the opening is close to the output shaft of the first driving member 33. For example, three hook claws 35 are provided, and the arc length of the opening is greater than the angle between any two adjacent hook claws 35. For ease of description, the three hook claws 35 are defined as the first hook claw, the second hook claw, and the third hook claw, respectively. When the first hook claw engages with the first drive member 33, the first hook claw hooks up the bagged powder and lifts it upward, and the locking block 353 on the first hook claw aligns with the locking ring 361. The central column 32 drives the first hook claw to continue rotating, so that the locking block 353 on the first hook claw engages with the locking ring 361, and at the same time disengages from the first drive member 33. Since the locking block 353 on the first hook claw engages with the locking ring 361, the first hook claw can still maintain the state of lifting the bagged powder after disengaging from the first drive member 33, and can make the bagged powder rotate along the locking ring 361, thereby moving the bagged powder to the top of the mixing tank 11 and being cut by the cutter 31, so that the powder falls into the mixing tank 11. As the central column 32 continues to rotate to move the first hook claw away from the mixing tank 11, since the retaining ring 361 has an open structure, when the first hook claw rotates away from the mixing tank 11, the retaining block 353 on the first hook claw disengages from the retaining ring 361, and then the first hook claw slides downward under the action of gravity, so that the claw bar 354 on the first hook claw comes into contact with the bagged powder on the conveyor belt 10. In this way, during the intermittent rotation of the central column 32, the three hook claws 35 can pass over the first drive member 33 and the mixing tank 11 in turn, thereby realizing the automatic feeding of bagged powder into the mixing tank 11, thereby improving work efficiency and reducing labor costs.

[0052] like Figures 10 to 11 As shown, in one embodiment, the retaining ring 361 has a shaking groove 3610.

[0053] It should be noted that a shaking groove 3610 is provided on the side of the retaining ring 361 away from the frame 20. There is a height difference between the inner bottom wall of the shaking groove 3610 and the side of the retaining ring 361 away from the frame 20, which causes the central column 32 to drive the retaining block 353 to slide into / out of the shaking groove 3610. During this sliding in / out process, the hook claw 35 slides in a wave-like manner, which causes the hook claw 35 to shake. In this way, the hook claw 35 moves the bagged powder to the top of the mixing tank 11, and after the bag is cut open by the cutter 31 and the powder falls into the mixing tank 11, the hook claw 35 shakes the bag so that the powder falls completely into the mixing tank 11, thereby improving the utilization rate of the bagged powder.

[0054] like Figures 1 to 2 , Figure 6 As shown, in one embodiment, a T-shaped rail is provided on the side of the frame 20 near the mixing tank 11. The cutter 31 includes a cutter holder 310, a blade 311, a clamping block 312, and a butterfly screw 313. A T-shaped groove is formed on one side of the cutter holder 310, which engages with the T-shaped rail, allowing the cutter holder 310 to slide on the frame 20. The clamping block 312 and the cutter holder 310 are tightened together by screws to clamp the blade 311. The butterfly screw 313 passes through the clamping block 312 and the cutter holder 310, and is screwed to the cutter holder 310, thus making the sliding position of the cutter holder 310 adjustable.

[0055] like Figure 4 , Figure 6 As shown, in one embodiment, the feeding assembly 30 further includes a waste hopper 37, which tends to have an arc-shaped structure and is set at an inclined angle on the frame 20. The upward end of the waste hopper 37 is close to the direction of the hook claw 35, and the waste hopper 37 is located below the support ring 36. Thus, when the locking block 353 on any hook claw 35 disengages from the locking ring 361, the hook claw 35 will cause the bag to slide downwards. During this process, the waste bag after the bagged powder is fed will fall into the waste hopper 37. Since the claw bar 354 on the hook claw 35 is rotatably set on the slide block 351, when the slide block 351 drives the claw bar 354 to slide downwards and abut against the waste hopper 37, the waste hopper 37 will push the claw bar 354 back towards the central column 32, causing the claw bar 354 to disengage from the waste bag. The waste bag is then released from the locking of the claw bar 354, allowing the waste bag to slide out of the waste hopper 37. In this way, each hook 35 passing through the waste hopper 37 can detach the waste bag during the descent, so that each hook 35 can take turns approaching the conveyor belt 10 for automatic feeding.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
