Description

Technical Field

[0001] The present invention relates to the technical field of powder material conveying, and in particular to a conveying device for processing powder raw materials. Background Art

[0002] Screw conveyors are commonly used to transport powdered raw materials during processing. Screw conveyors primarily use rotating screw blades to transport raw materials. However, for some viscous raw materials, the raw materials can easily stick to the screw blades during conveying, affecting the conveying process. Therefore, the stuck raw materials need to be cleaned.

[0003] Patent document CN117566351B discloses an anti-caking screw conveyor, comprising a conveying cylinder, a support base fixedly mounted at the bottom of the conveying cylinder, and a discharge port at the bottom thereof; a cylinder cover fixedly mounted at the top of the conveying cylinder, and an inlet port at one end of the cylinder cover; a reduction motor fixedly mounted on one side of the conveying cylinder, a rotating shaft fixedly connected to the output end of the reduction motor, and spiral blades fixedly mounted on the outer surface of the rotating shaft; a servo motor mounted on one side of the cylinder cover, and a first threaded rod fixedly connected to the conveying end of the servo motor. A cleaning block and a cleaning strip that cooperate with the inner wall of the conveying cylinder are mounted on the first threaded rod, and a nozzle is disposed within the conveying cylinder. The cleaning block, cleaning strip, and nozzle are used to clean the inner wall of the conveying cylinder and the spiral blades.

[0004] However, this solution also has the following problems: the conveying cylinder conveys the powdered raw materials through the rotation of the spiral blades. When using the nozzle to clean the raw materials stuck to the spiral blades, the raw materials in the conveying cylinder must be completely discharged and the machine must be stopped for operation. The raw materials stuck to the spiral blades cannot be cleaned during conveying. In addition, the raw materials will gradually stick to the spiral blades during conveying, causing the sticky raw materials to affect the conveying process. In severe cases, it may cause blockage and reduce the conveying efficiency. Summary of the Invention

[0005] The present invention provides a conveying device for processing powder raw materials, aiming to solve the problem in the related art that the machine needs to be stopped to clean the sticky raw materials, which affects the conveying efficiency.

[0006] The conveying equipment for processing powder raw materials of the present invention comprises: a main shaft rotatably assembled in a cylinder, a spiral piece on the main shaft, a driving member connected to the main shaft and driving the main shaft to rotate, and a cleaning component and a transmission component are provided on the cylinder;

[0007] The cleaning assembly includes: a cleaning rod arranged in a spiral shape around the main shaft, and a cleaning plate connected to the side of the cleaning rod. The cleaning rod is rotatably assembled on the main shaft and has the same pitch as the spiral plate. A plurality of cleaning plates are arranged along the length direction of the cleaning rod.

[0008] The transmission assembly connects the cleaning rod and the main shaft;

[0009] When the spiral slice rotates to transport raw materials, the transmission assembly drives the cleaning rod to rotate relative to the main shaft and approach the spiral slice. The cleaning rod rotates relative to the main shaft to clean the main shaft, and the cleaning plate rotates to abut against the spiral slice to clean the spiral slice.

[0010] The effect is that the driving member drives the main shaft to rotate, and the main shaft drives the spiral blades to rotate in the cylinder to transport the raw materials in the cylinder. At the same time, the driving member drives the cleaning rod to rotate with the main shaft through the transmission component. In addition, under the action of the transmission component, the cleaning rod can rotate relative to the main shaft while rotating with the main shaft. When the cleaning rod rotates relative to the main shaft, the raw materials adhered to the main shaft can be scraped off to clean the main shaft. At the same time, the cleaning rod drives the cleaning plate to move to abut against the spiral blades to clean the raw materials adhered to the spiral blades, thereby realizing continuous cleaning of the raw materials adhered to the main shaft and the spiral blades through the cleaning rod and the cleaning plate while transporting the raw materials, so as to reduce the phenomenon of raw material blockage and improve the transportation efficiency.

[0011] Preferably, the transmission assembly includes: a transmission sleeve, a main gear, an intermediate gear, and a slave gear. The transmission sleeve is connected to the cleaning rod and is rotatably assembled on the outside of the main shaft. The main gear is coaxially connected to the main shaft. The intermediate gear is rotatably assembled on the outside of the cylinder. The slave gear cooperates with the transmission sleeve. The intermediate gear is located between the main gear and the slave gear and meshes with both.

[0012] The effect is that when the main shaft rotates, it drives the main gear to rotate synchronously, the main gear drives the slave gear to rotate through the intermediate gear, and the transmission sleeve is driven to rotate through the slave gear, thereby driving the cleaning rod to rotate with the main shaft.

[0013] Preferably, the intermediate gear includes: a first gear meshing with the main gear, a second gear meshing with the slave gear, and the diameter of the first gear is smaller than the diameter of the main gear, so that the speed of the cleaning rod is greater than the speed of the main shaft and gradually approaches the spiral sheet.

[0014] The effect is that the diameter of the first gear is set to be smaller than the diameter of the main gear, so that the rotation speed of the cleaning rod is greater than the rotation speed of the main shaft. When the main shaft rotates, there is a speed difference between the cleaning rod and the main shaft. The cleaning rod can rotate relative to the main shaft, thereby driving the cleaning plate to move close to the spiral sheet while cleaning the main shaft to clean the spiral sheet.

[0015] Preferably, the second gear is an incomplete gear, and when the second gear is disengaged from the slave gear, the spiral piece rotates away from the cleaning plate.

[0016] The effect is that when the second gear is disengaged from the gear, the spiral piece rotates away from the cleaning plate, and at the same time, due to the self-rotation of the spiral piece, the other side thereof gradually approaches the cleaning plate, so that the cleaning plate can clean the other side of the spiral piece.

[0017] Preferably, an elastic member connected to the slave gear is provided on the outside of the transmission sleeve, and the slave gear is rotatably assembled on the outside of the transmission sleeve. The slave gear drives the transmission sleeve to rotate through the elastic member. A limiting component is provided on the cylinder, and the limiting component is connected to the slave gear so that the slave gear stops rotating after disengaging from the second gear. Then the elastic member drives the cleaning plate to rotate in the opposite direction and abut against the other side of the spiral sheet to clean that side.

[0018] The effect is that the transmission sleeve is driven to rotate by the elastic member from the gear until the cleaning plate abuts against the spiral piece. During the process, the elastic member is deformed by the force and accumulates force. After the second gear is disengaged from the slave gear, the limit assembly cooperates with the slave gear to limit the slave gear. Then the elastic member drives the cleaning rod and the cleaning plate to rotate in the opposite direction, and assists in driving the cleaning plate to abut against the other side of the spiral piece.

[0019] Preferably, a ratchet is coaxially and fixedly provided on the slave gear, the slave gear is connected to the elastic member through the ratchet, a pawl that cooperates with the ratchet is rotatably provided on the cylinder, when the second gear is engaged with the slave gear, the ratchet rotates relative to the pawl, and when the second gear is disengaged from the slave gear, the pawl engages with the ratchet.

[0020] The effect is that when the second gear is disengaged from the slave gear, the slave gear no longer rotates with the main shaft. At this time, the pawl is engaged with the ratchet wheel to prevent the slave gear from rotating in the opposite direction, so that the subsequent elastic member can drive the cleaning rod to move in the opposite direction.

[0021] Preferably, the cleaning plate is rotatably assembled on the cleaning rod, and the rotation axis of the cleaning plate is perpendicular to the main shaft. After the cleaning plate rotates to the spiral piece, the side surface of the cleaning plate abuts against the spiral piece and then gradually rotates to fit the spiral piece.

[0022] The effect is that after the cleaning plate rotates to the spiral plate, the side of the cleaning plate first abuts against the spiral plate, and then the cleaning plate rotates, and its side slides relative to the spiral plate until the cleaning plate and the spiral plate are completely abutted. During the process, the raw materials adhered to the spiral plate can be scraped off, thereby improving the cleaning effect of the spiral plate.

[0023] Preferably, a rotating member is provided at the rotating shaft of the cleaning plate, and the rotating member is connected to the cleaning rod to drive the cleaning plate to rotate, so that the cleaning plate is in an inclined state relative to the spiral sheet when it rotates to the spiral sheet.

[0024] The effect is that the rotating member causes the cleaning plate to be in an inclined state when it rotates to the spiral slice, so that the side of the cleaning plate first contacts the spiral slice, and as the cleaning plate continues to move, the side of the cleaning plate can move relative to the spiral slice to scrape the raw materials on the spiral slice. In addition, after the cleaning plate separates from the spiral slice, the rotating member can drive the cleaning plate to rotate to the original state so that the spiral slice can be cleaned again.

[0025] Preferably, the rotating sleeve on the main shaft is provided with a stabilizing sleeve, and the stabilizing sleeve is connected to the end of the cleaning rod away from the transmission sleeve.

[0026] The effect is that the stabilizing sleeve and the transmission sleeve respectively support the two ends of the cleaning rod, thereby improving the stability of the cooperation between the cleaning rod and the main shaft.

[0027] Preferably, a plurality of pawls are arranged at intervals around the ratchet wheel, and a torsion spring is provided at the rotating shaft of the pawl for driving the pawl to rotate toward the ratchet wheel.

[0028] The effect is that multiple pawls are provided to improve the stability of the cooperation between the pawls and the ratchet wheel.

[0029] Beneficial effects:

[0030] The present invention provides a cleaning rod on the main shaft and a cleaning plate on the cleaning rod. When the raw materials are conveyed, the cleaning rod can rotate relative to the main shaft to scrape off the raw materials adhered to the main shaft, and at the same time drive the cleaning plate to move to abut against the side of the spiral sheet to clean the raw materials adhered to the spiral sheet, thereby achieving the goal of cleaning the adhered raw materials while conveying the raw materials, thereby improving the conveying efficiency of the raw materials.

[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0042] like Figures 1 to 8 As shown, the conveying equipment for processing powder raw materials of the present invention includes a base 1, a conveying assembly, a cleaning assembly 6, and a transmission assembly 7. The conveying assembly is arranged on the base 1 for conveying raw materials, the cleaning assembly 6 is arranged inside the conveying assembly, and the transmission assembly 7 is connected to the cleaning assembly 6. When the conveying assembly conveys raw materials, the transmission assembly 7 drives the cleaning assembly 6 to clean the raw materials adhered to the conveying assembly during conveyance.

[0043] Reference Figure 1 、 Figure 2 、 Figure 3 The conveying assembly includes: a cylinder 2, a main shaft 3, a spiral blade 4, and a driving member 5. The cylinder 2 is placed horizontally, the main shaft 3 is coaxially arranged in the cylinder 2, and the main shaft 3 is rotatably assembled in the cylinder 2. The spiral blade 4 is arranged on the side of the main shaft 3 and is arranged in a spiral shape along the length direction of the main shaft 3. The driving member 5 is arranged on the machine base 1. The driving member 5 is configured as a motor, and the output end of the driving member 5 is connected to the main shaft 3. A feed hopper 21 and a discharge pipe 22 are respectively provided on the cylinder 2 and are connected to the interior thereof. The feed hopper 21 and the discharge pipe 22 are respectively provided near the two ends of the cylinder 2. The feed hopper 21 is provided above the cylinder 2, and the discharge pipe 22 is provided below the cylinder 2.

[0044] The raw materials enter the barrel 2 through the feed hopper 21 , the driving member 5 drives the main shaft 3 to rotate, and the rotation of the main shaft 3 drives the spiral piece 4 to rotate, thereby conveying the raw materials, and finally discharged through the discharge pipe 22 .

[0045] Reference Figure 2 、 Figure 3The cleaning assembly 6 includes a cleaning rod 61 and a cleaning plate 62. The cleaning rod 61 is arranged on the side of the main shaft 3 and is spirally arranged around the main shaft 3. The cleaning rod 61 has the same shape as the spiral plate 4, that is, the cleaning rod 61 and the spiral plate 4 have the same pitch. The cleaning rod 61 is rotatably assembled on the main shaft 3, that is, the inner side of the cleaning rod 61 is in sliding contact with the outer side of the main shaft 3. The cleaning plate 62 is connected to the cleaning rod 61, and a plurality of cleaning plates 62 are arranged along the length direction of the cleaning rod 61. The transmission assembly 7 connects the cleaning rod 61 and the main shaft 3.

[0046] When the driving member 5 drives the main shaft 3 and the spiral plate 4 to rotate, the cleaning rod 61 is driven to rotate along with the main shaft 3 through the transmission assembly 7. At the same time, under the action of the transmission assembly 7, the cleaning rod 61 rotates relative to the main shaft 3. At this time, the cleaning rod 61 cleans the raw materials adhered to the main shaft 3. At the same time, the cleaning rod 61 drives the cleaning plate 62 to move. Since the pitch of the cleaning rod 61 is the same as the pitch of the spiral plate 4, the cleaning rod 61 can rotate to fit the spiral plate 4, and at the same time drive the cleaning plate 62 to move to abut against the spiral plate 4, removing the raw materials adhered to the spiral plate 4, and cleaning the spiral plate 4 through the cleaning plate 62.

[0047] Reference Figure 3 、 Figure 8 The cleaning plate 62 is rotatably assembled on the cleaning rod 61 , and the rotation axis of the cleaning plate 62 is perpendicular to the main shaft 3 .

[0048] When the cleaning plate 62 rotates to the spiral piece 4 along with the cleaning rod 61 , the cleaning plate 62 can rotate and gradually abut against the spiral piece 4 to scrape off the raw materials adhered to the spiral piece 4 .

[0049] At the same time, when the raw materials are being transported, the cleaning plate 62 turns the raw materials to reduce the agglomeration of the raw materials during transportation. And when the raw materials need to be dried during transportation, the turning of the raw materials can lift the raw materials accumulated at the bottom of the cylinder 2, so that the hot drying air can fully contact the raw materials, thereby improving the drying effect of the raw materials.

[0050] Reference Figure 2 、 Figure 3 In addition, multiple cleaning plates 62 are provided, and a gap is left between each two cleaning plates 62. The cleaning plates 62 can screen out the agglomerated raw materials when rotating. When the cleaning plates 62 are close to the spiral plates 4, the agglomerated raw materials collide with and are squeezed on the spiral plates 4, so as to crush the agglomerated raw materials.

[0051] Reference Figure 2 、 Figure 8A rotating member 621 is provided at the rotating shaft of the cleaning plate 62, and the rotating member 621 is configured as a torsion spring. The torsion spring is used to drive the cleaning plate 62 to rotate, so that when the cleaning plate 62 rotates to the spiral piece 4, it is in an inclined state relative to the spiral piece 4, so that the side of the cleaning plate 62 cooperates with the spiral piece 4, so that the cleaning plate 62 can rotate to abut against the spiral piece 4.

[0052] Reference Figure 4 、 Figure 5 The transmission assembly 7 includes: a transmission sleeve 71, a main gear 72, an intermediate gear 73, and a slave gear 74. The transmission sleeve 71 is rotatably assembled on the outside of the main shaft 3, and one end of the transmission sleeve 71 is connected to the cleaning rod 61, and the other end extends to the outside of the cylinder 2. The main gear 72, the intermediate gear 73, and the slave gear 74 are all arranged on the outside of the cylinder 2. The main gear 72 is coaxially connected to the main shaft 3, and the intermediate gear 73 is rotatably assembled on the cylinder 2. The slave gear 74 cooperates with the transmission sleeve 71. The intermediate gear 73 is arranged on one side of the slave gear 74 and the main gear 72, and the intermediate gear 73 is meshed with the main gear 72 and the intermediate gear 73 at the same time.

[0053] Reference Figure 4 、 Figure 5 、 Figure 6 The intermediate gear 73 includes: a first gear 731 and a second gear 732. The first gear 731 and the second gear 732 are coaxially arranged, and the first gear 731 and the second gear 732 rotate synchronously. The first gear 731 is engaged with the main gear 72, and the second gear 732 is engaged with the slave gear 74. The diameter of the first gear 731 is smaller than the diameter of the main gear 72.

[0054] When the main shaft 3 rotates, the main gear 72 drives the first gear 731 and the second gear 732 to rotate, and the second gear 732 drives the slave gear 74 and the transmission sleeve 71 to rotate synchronously, thereby driving the cleaning rod 61 to rotate along with the main shaft 3. In addition, by setting the diameter of the first gear 731 to be smaller than the diameter of the main gear 72, the transmission ratio between the main gear 72 and the first gear 731 is adjusted, so that the rotation speed of the transmission sleeve 71 is greater than the rotation speed of the main shaft 3, thereby achieving the rotation of the cleaning rod 61 relative to the main shaft 3, so that the cleaning rod 61 moves close to the spiral plate 4 to clean it.

[0055] Reference Figure 6 The second gear 732 is set as an incomplete gear, that is, as the second gear 732 rotates, the second gear 732 will disengage from the slave gear 74. At this time, the transmission sleeve 71 and the cleaning rod 61 lose driving force, and the main shaft 3 drives the spiral piece 4 to rotate continuously, so that the spiral piece 4 gradually moves away from the cleaning plate 62. When the second gear 732 engages with the slave gear 74 again, it drives the cleaning plate 62 to move closer to the spiral piece 4 again, thereby achieving the effect of reciprocating cleaning of the spiral piece 4.

[0056] Reference Figure 3 、 Figure 4 、 Figure 5 The transmission sleeve 71 is provided with an elastic member 8 on its exterior. The elastic member 8 is configured as a torsion spring and is provided along the length of the transmission sleeve 71. The slave gear 74 is rotatably assembled on the exterior of the transmission sleeve 71. The elastic member 8 is connected to the transmission sleeve 71 and the slave gear 74, respectively. A limit assembly 9 is provided on the cylinder 2. The limit assembly 9 cooperates with the slave gear 74 to limit the rotation direction of the slave gear 74, so that the slave gear 74 can only rotate in the same direction as the rotation of the main shaft 3. That is, after the second gear 732 is disengaged from the slave gear 74, the limit assembly 9 fixes the slave gear 74.

[0057] When the second gear 732 is engaged with the slave gear 74, the second gear 732 rotates with the main shaft 3, driving the slave gear 74 to rotate. The slave gear 74 rotates outside the transmission sleeve 71. The slave gear 74 drives the transmission sleeve 71 to rotate through the elastic member 8, thereby driving the cleaning plate 62 to abut against the spiral plate 4. During this process, the elastic member 8 is deformed by the force. After the second gear 732 is disengaged from the slave gear 74, the limit assembly 9 fixes the slave gear 74, and the spiral plate 4 continues to rotate away from the cleaning plate 62. At the same time, the transmission sleeve 71 rotates in the opposite direction to the spiral plate 4 under the action of the elastic member 8. At this time, the cleaning rod 61 rotates on the main shaft 3 in the opposite direction relative to the main shaft 3 until the cleaning plate 62 rotates to abut against the other side of the spiral plate 4, thereby cleaning the raw materials adhered to the other side of the spiral plate 4.

[0058] After cleaning the other side of the spiral sheet 4, the second gear 732 rotates again to engage with the slave gear 74, and the above operation is repeated, so that the cleaning plate 62 abuts against both sides of the spiral sheet 4 back and forth to clean the bonded raw materials of the spiral sheet 4.

[0059] Reference Figure 4 、 Figure 5 、 Figure 7 The limiting assembly 9 includes a ratchet 91 and a pawl 92. The ratchet 91 is coaxially connected to the slave gear 74 and rotates synchronously with the slave gear 74. That is, the ratchet 91 is also rotatably sleeved on the outside of the transmission sleeve 71. The pawl 92 is rotatably arranged on the outside of the cylinder 2 and can be rotated to engage with the ratchet 91. A plurality of pawls 92 are arranged at intervals around the ratchet 91. A torsion spring is provided at the rotation axis of the pawl 92 to drive the pawl 92 to engage with the ratchet 91. The end of the pawl 92 facing away from the ratchet 91 is tilted in the direction of rotation away from the ratchet 91.

[0060] When the second gear 732 is engaged with the slave gear 74, the ratchet 91 rotates past the pawl 92. When the second gear 732 is disengaged from the slave gear 74, the pawl 92 is engaged with the ratchet 91 under the action of the torsion spring, restricting the ratchet 91 and reducing the reverse rotation of the ratchet 91, so that the cleaning rod 61 can be driven by the spring 8 to rotate in the reverse direction to clean the other side of the spiral plate 4.

[0061] Reference Figure 2 A stabilizing sleeve 31 is provided on the main shaft 3, and the stabilizing sleeve 31 is arranged at one end of the cleaning rod 61 away from the transmission sleeve 71. The cleaning rod 61 is supported by the transmission sleeve 71 and the stabilizing sleeve 31, thereby improving the stability of the cooperation between the cleaning rod 61 and the main shaft 3.

[0062] The implementation principle of the present invention is: when conveying raw materials, the main gear 72 rotates synchronously with the main shaft 3, and at the same time drives the first gear 731 and the second gear 732 to rotate synchronously. During this process, the second gear 732 engages and disengages with the slave gear 74 reciprocatingly.

[0063] When the second gear 732 is engaged with the slave gear 74, the slave gear 74 is driven to rotate synchronously. Under the action of the elastic member 8, the slave gear 74 drives the transmission sleeve 71 and the cleaning rod 61 to rotate along with the main shaft 3. At the same time, the elastic member 8 undergoes elastic deformation, and under the action of the transmission ratio of the first gear 731 and the main gear 72, the rotation speed of the cleaning rod 61 is greater than the rotation speed of the main shaft 3, so that the cleaning rod 61 rotates relative to the main shaft 3 and drives the cleaning plate 62 to move to abut against the spiral piece 4, thereby cleaning the raw materials adhered to the main shaft 3 and the spiral piece 4.

[0064] The second gear 732 is an incomplete gear. When the gear portion of the second gear 732 is separated from the slave gear 74 , the second gear 732 is disengaged from the slave gear 74 .

[0065] When the second gear 732 is disengaged from the gear 74, the pawl 92 is engaged with the ratchet 91, and the elastic member 8 drives the cleaning rod 61 to rotate in the opposite direction through the transmission sleeve 71. At the same time, the rotation direction of the spiral piece 4 remains unchanged, and it continues to rotate away from the cleaning rod 61, so that the other side gradually approaches the cleaning rod 61, and under the action of the elastic member 8, drives the cleaning rod 61 to rotate in the opposite direction until the cleaning rod 61 and the cleaning plate 62 move to the other side of the spiral piece 4, and the raw materials adhered to the other side of the spiral piece 4 are cleaned.

[0066] By providing the cleaning rod 61 and the cleaning plate 62, the cleaning rod 61 cleans the main shaft 3 and the cleaning plate 62 cleans both sides of the spiral sheet 4 while the raw materials are being conveyed, thereby reducing blockage and improving the efficiency of conveying the raw materials.

[0067] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
