Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and particularly to a spiral chain plate elevator and a using method thereof. Background Technique

[0002] A spiral chain plate elevator is a mechanical device used for conveying materials in a vertical or inclined direction. It combines the advantages of spiral conveying and chain plate conveying and can efficiently and stably transport various types of materials. This device is widely used in fields such as food processing, chemical industry, pharmaceutical industry, and agriculture, and is particularly suitable when materials need to be lifted from a lower place to a higher place.

[0003] When the existing spiral chain plate elevator lifts materials, the materials to be conveyed are placed above multiple chain plates. When the shapes of the materials to be conveyed are irregular and the mass distributions are uneven, the materials placed on the multiple chain plates will not be in complete contact with the multiple chain plates at the bottom, that is, one or more chain plates at the bottom of the materials cannot contact the materials. When the number of chain plates in contact with the materials is small, the frictional force exerted on the materials by the elevator will be small, and the materials are likely to slide on the chain plates during the conveying process.

[0004] Moreover, the positions of the chain plates in the existing elevator cannot rotate adaptively. When the materials are placed on the elevator, in fact, the materials are supported on multiple chain plates. When the materials are supported on multiple chain plates, the materials can only be in partial contact with the bottom chain plates, which results in that the positions of the chain plates directly below the materials cannot be in full contact with the materials, and further leads to a small contact area between the materials and the chain plates, so that the frictional force received by the materials is small, which also makes the materials likely to slide on the chain plates during the conveying process.

[0005] Therefore, the existing spiral chain plate elevator has the problems that the materials are not in complete contact with the bottom chain plates and the contact area with the chain plates is small, resulting in a small frictional force on the materials, and causing the materials to be likely to slide on the chain plates during the conveying process. For this reason, we propose a spiral chain plate elevator and a using method thereof. Summary of the Invention

[0020] Preferably, there is always a gap between two adjacent sleeve plates in the vertical direction.

[0021] A method for using a spiral chain plate elevator comprises the following steps:

[0022] S1. When in use, place the material on the chain plate assembly, and the chain plate assembly transports the material;

[0023] S2. The chain plate assembly supports the material, and the material generates pressure on each chain plate assembly it contacts. The pressure causes the anti-skid pad and the sleeve plate in the chain plate assembly to move downward, so that the material contacts the chain plate assembly that is not in contact. The pressure causes the anti-skid pad, sleeve plate and guide plate in the chain plate assembly to deflect on the guide seat, thereby increasing the contact area between the material and the chain plate assembly.

[0024] S3, when the anti-skid pad and the sleeve plate move downward, the clamping rod enters the through-hole and passes through the through-hole, and the clamping rod and the anti-skid pad collide with each other, so that the clamping rod supports the material through the anti-skid pad;

[0025] S4. After the material is transported, the pressure exerted on the anti-skid pad, sleeve plate, and guide plate disappears and they return to their original positions under elastic support.

[0026] The present invention has the following beneficial effects:

[0027] 1. In the present invention, a structure of a guide plate and a sleeve plate is provided. The guide plate elastically supports the sleeve plate. After the material is placed above the anti-slip pad on the sleeve plate, the material presses the contacted anti-slip pad and the sleeve plate downward, reducing the placement height of the material on the chain plate assembly. This enables the material to come into contact with the chain plate assembly that it couldn't originally touch at the bottom, and after the material contacts more chain plate assemblies, the friction area with the material is increased, thereby increasing the frictional force of the elevator on the material. As a result, during the process of conveying the material, the material will not slide on the chain plate, and the conveying of the material is more stable.

[0028] 2. In the present invention, a structure of a guide seat, a guide plate, an arc-shaped chute, and an arc-shaped abutting shaft is provided. After the material is placed above the anti-slip pad, the material will exert a lateral pressure on the anti-slip pad, the sleeve plate, and the guide plate, causing the guide plate to deflect on the guide seat and making the anti-slip pad and the sleeve plate rotate synchronously. After rotation, the anti-slip pad will come into contact with a larger area of the bottom of the material, ensuring sufficient contact between the material and the anti-slip pad. This greatly increases the friction area with the material, thereby increasing the frictional force of the elevator on the material. As a result, during the process of conveying the material, the material will not slide on the chain plate, and the conveying of the material is more stable. The setting of the arc-shaped chute facilitates the directional rotation of the guide plate, and the setting of the arc-shaped abutting shaft enables the guide plate in the device to automatically reset after the material conveying is completed.

[0029] 3. In the present invention, by setting a clamping rod on the guide plate in the inner cavity, when the material presses the anti-slip pad and the sleeve plate downward, the clamping rod will gradually come into contact with the anti-slip pad, and finally the clamping rod will support the material through the anti-slip pad. The clamping rod causes the anti-slip pad to deform. The greater the pressure of the material on the clamping rod, the greater the deformation amplitude of the anti-slip pad caused by the clamping rod. The deformed part of the anti-slip pad becomes uneven, increasing the friction coefficient of the deformed part of the anti-slip pad and thus increasing the frictional force of the anti-slip pad on the material, thereby improving the anti-slip ability of the chain plate assembly. The deformation amplitude of the anti-slip pad caused by the clamping rod is affected by the self-weight of the material. The lighter the material, the smaller the deformation amplitude of the anti-slip pad or even no deformation occurs, which plays a good protective role for the anti-slip pad and makes the anti-slip pad not easily damaged.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0044] Please refer to Figure 1 - Figure 10 As shown in the figure, a spiral chain plate elevator includes a base 1, a frame 2 fixedly installed above the base 1, a driving device 3 fixedly installed at the lower corner on one side of the frame 2, and a conveying device movably arranged inside the frame 2. The driving device 3 drives the conveying device. The conveying device is composed of a guide rail assembly 4 and a plurality of chain plate assemblies 5. The guide rail assembly 4 guides the chain plate assembly 5 to move along a predetermined path. The chain plate assembly 5 includes a positioning seat 51 arranged on the guide rail assembly 4, a guide seat 52 fixedly arranged above the positioning seat 51, a guide plate 53 arranged above the guide seat 52, a sleeve plate 54 sleeved above the guide plate 53, and an anti-slip pad 55 fixedly arranged above the sleeve plate 54;

[0045] An arc-shaped chute 8 adapted to the guide seat 52 is formed at the bottom of the guide plate 53. The guide seat 52 is movably arranged below the arc-shaped chute 8, and the guide plate 53 rotates above the guide seat 52; the guide plate 53 can rotate reciprocally on the guide seat 52.

[0046] A plurality of arc-shaped abutting shafts 6 are elastically connected to both sides of the guide seat 52 respectively. The arc-shaped abutting shafts 6 abut against the inner wall of the arc-shaped chute 8; the number of arc-shaped abutting shafts 6 on both sides of the guide seat 52 is the same and corresponds one by one. Without external force, the supporting forces of the arc-shaped abutting shafts 6 on both sides of the guide seat 52 on the guide plate 53 are the same. The pressure generated by the material on the sleeve plate 54 causes the sleeve plate 54 and the guide plate 53 to rotate on the guide seat 52. After removing the pressure of the material, the arc-shaped abutting shafts 6 reset the guide plate 53 on the guide seat 52 under elastic support.

[0047] The guide plate 53 and the sleeve plate 54 are elastically connected; the guide plate 53 elastically supports the sleeve plate 54, so that the sleeve plate 54 will move towards the guide plate 53 after being subjected to the material pressure.

[0048] There is an inner cavity 9 between the sleeve plate 54 and the guide plate 53, and a plurality of clamping rods 10 are fixedly arranged above the guide plate 53. A through hole 7 for the clamping rod 10 to penetrate the plate surface of the sleeve plate 54 is provided inside the sleeve plate 54. When the material presses the sleeve plate 54 downward, the anti-skid pad 55 and the sleeve plate 54 move downward, and the clamping rod 10 enters the through hole 7 and penetrates the through hole 7. The clamping rod 10 and the anti-skid pad 55 collide with each other, so that the clamping rod 10 supports the material through the anti-skid pad 55, and the friction between the anti-skid pad 55 and the material at the position where the clamping rod 10 collide is greatly increased, so that the material will not move on the anti-skid pad 55.

[0049] During the use of the device, materials are placed on multiple chain plate assemblies 5, and pressure is generated on each chain plate assembly 5 that contacts the materials. The pressure causes the anti-skid pads 55 and the sleeves 54 in the chain plate assemblies 5 to move downward, and causes the anti-skid pads 55, the sleeves 54, and the guide plates 53 in the chain plate assemblies 5 to deflect on the guide seat 52. During the downward movement of the anti-skid pads 55 and the sleeves 54, the clamping rod 10 passes through the opening 7, and the clamping rod 10 and the anti-skid pads 55 collide with each other, so that the clamping rod 10 supports the materials through the anti-skid pads 55. After the material is transported, the pressure of the materials on the anti-skid pads 55, the sleeves 54, and the guide plates 53 disappears, and they return to their original positions under the provided elastic structure.

[0050] When the existing spiral chain plate elevator is lifting materials, the materials are placed on multiple chain plates. Due to the irregular shape and uneven mass distribution of the materials, the materials will not be completely in contact with the multiple chain plates at the bottom, that is, there are chain plates at the bottom of the materials that cannot contact the materials. The materials are in contact with fewer chain plates, which will result in less friction on the materials, and the materials are easy to slide on the chain plates during transportation. In order to solve this problem, the elevator in this design optimizes the chain plate assembly 5 on the guide rail assembly 4, so that the height of the chain plate assembly 5 can be adaptively adjusted at its own height according to the pressure of the materials. By setting the structure of the guide plate 53 and the sleeve plate 54, the guide plate 53 elastically supports the sleeve plate 54. When the material is placed on the anti-skid pad 55 on the sleeve plate 54, the material is pressed downward by the contacting anti-skid pad 55 and the sleeve plate 54, so that the placement height of the material on the chain plate assembly 5 is reduced, and the material can contact the chain plate assembly 5 that was originally unable to contact the bottom. After the material contacts more chain plate assemblies 5, the friction area of ​​the material is increased, thereby increasing the friction force of the elevator on the material, so that the material will not slip on the chain plate during the material transportation process, and the material transportation is more stable.

[0051] When the existing spiral chain plate elevator is lifting materials, since the position of the chain plates in the existing elevator cannot rotate, when the material is placed on multiple chain plates, the material can only make partial contact with the bottom chain plate, and the position of the chain plate directly below the material cannot make full contact with the material, resulting in a small contact area between the material and the chain plate, and the friction force received by the material is small. This makes it easy for the material to slide on the chain plate during the conveying process. To solve this problem, the elevator in this design optimizes the chain plate assembly 5 on the guide rail assembly 4, enabling the chain plate assembly 5 to rotate to increase the contact area with the material. By setting up the structure of the guide seat 52, the guide plate 53, the arc-shaped chute 8, and the arc-shaped abutting shaft 6, when the material is placed above the anti-slip pad 55, the material will generate a lateral pressure on the anti-slip pad 55, the sleeve plate 54, and the guide plate 53, causing the guide plate 53 to deflect on the guide seat 52, making the anti-slip pad 55 and the sleeve plate 54 rotate synchronously. After rotation, the anti-slip pad 55 will make a larger area of contact with the bottom of the material, ensuring full contact between the material and the anti-slip pad 55. This greatly increases the friction area of the material, thereby increasing the friction force of the elevator on the material, ensuring that the material will not slide on the chain plate during the material conveying process and making the material conveying more stable. The setting of the arc-shaped chute 8 facilitates the directional rotation of the guide plate 53, and the setting of the arc-shaped abutting shaft 6 enables the guide plate 53 in the device to automatically reset after the material conveying is completed.

[0052] To further improve the anti-slip ability of the chain plate assembly 5, the device is provided with a clamping rod 10 on the guide plate 53 in the inner cavity 9. When the material presses the anti-slip pad 55 and the sleeve plate 54 downward, the clamping rod 10 will gradually come into contact with the anti-slip pad 55. Eventually, the clamping rod 10 will support the material through the anti-slip pad 55. The clamping rod 10 deforms the anti-slip pad 55. The greater the pressure of the material on the clamping rod 10, the greater the deformation amplitude of the anti-slip pad 55 caused by the clamping rod 10. The deformed part of the anti-slip pad 55 becomes uneven, increasing the friction coefficient of the deformed part of the anti-slip pad 55 and thus increasing the friction force of the anti-slip pad 55 on the material, thereby improving the anti-slip ability of the chain plate assembly 5. The deformation amplitude of the anti-slip pad 55 caused by the clamping rod 10 is affected by the self-weight of the material. The lighter the material, the smaller the deformation amplitude of the anti-slip pad 55 or even no deformation occurs, which plays a good protective role for the anti-slip pad 55 and makes the anti-slip pad 55 not easily damaged. The surface of the anti-slip pad 55 is a planar structure and is not easily damaged.

[0053] Among them, a threaded groove 11 is opened at the end of the guide plate 53, and a limiting rod 12 is threadedly connected inside the threaded groove 11. A limiting port 13 is opened on the side wall of the sleeve plate 54, and the limiting rod 12 is located inside the limiting port 13.

[0054] To prevent the sleeve plate 54 from falling off the guide plate 53, a limiting rod 12 is installed on the guide plate 53. The limiting rod 12 is stuck in the limiting opening 13. While the sleeve plate 54 moves on the guide plate 53, the limiting rod 12 limits the sleeve plate 54 to prevent the sleeve plate 54 from detaching from the guide plate 53.

[0055] Wherein, a baffle 14 is fixedly arranged below the end of the sleeve plate 54, and the baffle 14 is located at the end of the guide seat 52.

[0056] To prevent the guide plate 53 from moving along the guide seat 52 and prevent impurities from entering the inside of the arc-shaped chute 8, a baffle 14 is arranged below the end of the sleeve plate 54.

[0057] Wherein, a plurality of arc-shaped slot holes 15 are formed in the upper sides of the side walls on both sides of the guide seat 52. The number of the arc-shaped slot holes 15 is the same as that of the arc-shaped abutting shafts 6 and they are in one-to-one correspondence. A first spring 16 is arranged inside the arc-shaped slot holes 15. One end of the arc-shaped abutting shaft 6 extends into the inside of the arc-shaped slot holes 15 and is inserted into the first spring 16. A snap ring 17 is fixedly arranged on the side surface of the arc-shaped abutting shaft 6. The snap ring 17 is located inside the arc-shaped slot holes 15. The outer side surface of the snap ring 17 is attached to the side wall of the arc-shaped slot holes 15. One end of the first spring 16 abuts against one side of the snap ring 17, and the other end of the first spring 16 abuts against the inner wall deep inside the arc-shaped slot holes 15. There is a gap between the other side of the snap ring 17 and the shallow inner wall at the orifice of the arc-shaped slot holes 15.

[0058] After the material conveying is completed, to facilitate the reset of the guide plate 53 by the arc-shaped abutting shaft 6, in this design, the first spring 16 is used to support the snap ring 17, pushing the arc-shaped abutting shaft 6 to move outside the arc-shaped slot holes 15, and the arc-shaped abutting shaft 6 pushes the guide plate 53 to reset.

[0059] Wherein, a limiting shaft 27 is fixedly arranged on the inner wall deep inside the arc-shaped slot holes 15. The limiting shaft 27 is located inside the first spring 16. A limiting hole 18 is formed at one end of the arc-shaped abutting shaft 6 extending into the inside of the arc-shaped slot holes 15, and the limiting shaft 27 is movably arranged inside the limiting hole 18.

[0060] To prevent the first spring 16 from being twisted inside the arc-shaped slot holes 15, a limiting shaft 27 is arranged inside the first spring 16. The limiting shaft 27 prevents the first spring 16 from being twisted. The limiting shaft 27 moves inside the limiting hole 18 to limit the arc-shaped abutting shaft 6, making the movement of the arc-shaped abutting shaft 6 inside the arc-shaped slot holes 15 smoother.

[0061] Among them, a plurality of inner grooves 19 are formed above the guide plate 53. A second spring 20 is disposed inside each inner groove 19. One end of the second spring 20 abuts against the top wall of the sleeve plate 54, and the other end of the second spring 20 abuts against the bottom wall of the inner groove 19. A limiting sleeve 21 is fixedly arranged at the bottom of the inner groove 19. A connecting shaft 22 is inserted above the limiting sleeve 21. The connecting shaft 22 is fixedly connected to the top wall of the sleeve plate 54. Both the limiting sleeve 21 and the connecting shaft 22 are located inside the second spring 20.

[0062] To facilitate the elastic connection between the sleeve plate 54 and the guide plate 53, the second spring 20 is used to connect the sleeve plate 54 and the guide plate 53 respectively. The second spring 20 is in a compressed state to support the sleeve plate 54. The limiting sleeve 21 and the connecting shaft 22 are used to prevent the second spring 20 from deforming. The connecting shaft 22 slides inside the limiting sleeve 21.

[0063] Among them, a plurality of fixing plates 23 are evenly spaced above the guide plate 53. Each fixing plate 23 is fixedly connected to the guide plate 53. The clamping rods 10 are equally arranged above each fixing plate 23. The clamping rods 10 are evenly spaced above the fixing plates 23. A plurality of through holes 7 are formed inside the sleeve plate 54. The number of the through holes 7 is the same as that of the fixing plates 23 and they correspond to each other one by one. A retaining plate 24 is fixedly arranged inside each through hole 7. A plurality of through holes 25 are formed inside the retaining plate 24. The number of the through holes 25 on the retaining plate 24 is the same as that of the clamping rods 10 on the fixing plates 23 and they correspond to each other one by one. The length of the clamping rod 10 is greater than the depth of the through hole 25.

[0064] To prevent the clamping rod 10 from deforming under force when supporting an object, the retaining plate 24 is arranged inside the through hole 7. When the material presses down the sleeve plate 54, the clamping rod 10 extends into the inside of the through hole 25, and the retaining plate 24 protects the clamping rod 10.

[0065] Among them, a dust-proof sheet 26 is fixedly arranged on one side of the baffle 14. The dust-proof sheet 26 is attached to the guide seat 52.

[0066] Among them, there is always a gap between two adjacent sleeve plates 54 in the vertical direction, so that the two adjacent sleeve plates 54 do not interfere with each other when rotating.

[0067] A using method of a spiral chain plate elevator includes the following steps:

[0068] S1. During use, place the material above the chain plate assembly 5, and the chain plate assembly 5 conveys the material.

[0069] S2, the chain plate assembly 5 supports the material, and the material generates pressure on each chain plate assembly 5 that it contacts, and the pressure causes the anti-skid pad 55 and the sleeve plate 54 in the chain plate assembly 5 to move downward, so that the material contacts the chain plate assembly 5 that it has not contacted, and the pressure causes the anti-skid pad 55, the sleeve plate 54 and the guide plate 53 in the chain plate assembly 5 to deflect on the guide seat 52, thereby increasing the contact area between the material and the chain plate assembly 5;

[0070] S3, when the anti-skid pad 55 and the sleeve plate 54 move downward, the clamping rod 10 enters the through-port 7 and passes through the through-port 7, and the clamping rod 10 and the anti-skid pad 55 collide with each other, so that the clamping rod 10 supports the material through the anti-skid pad 55;

[0071] S4. After the material is conveyed, the pressure of the material on the anti-skid pad 55, the sleeve plate 54, and the guide plate 53 disappears, and they return to their original positions under elastic support.
