Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to a spiral chain plate elevator and a use method thereof. Background Art

[0002] The spiral chain elevator is a mechanical device used to transport materials in a vertical or inclined direction. It combines the advantages of spiral conveying and chain conveying, and can efficiently and stably transport various types of materials. This equipment is widely used in food processing, chemical, pharmaceutical, agricultural and other fields, especially when materials need to be lifted from low to high.

[0003] When the existing spiral chain plate elevator is lifting materials, the materials to be transported are placed on multiple chain plates. When the materials to be transported are irregular in shape and uneven in mass distribution, the materials placed on multiple chain plates will not be completely in contact with the materials and the multiple chain plates at the bottom, that is, there will be one or more chain plates at the bottom of the materials that cannot contact the materials. When the materials contact fewer chain plates, the friction force on the materials on the elevator will be small, and the materials are easy to slide on the chain plates during transportation.

[0004] In addition, the position of the chain plates in the existing elevators cannot rotate adaptively. When the materials are placed on the elevator, they are actually placed on multiple chain plates. When the materials are placed on multiple chain plates, the materials can only partially contact the bottom chain plate, which results in the chain plate located directly below the materials not being able to fully contact the materials, which in turn results in a small contact surface between the materials and the chain plates, resulting in a small friction force on the materials, which also makes it easy for the materials to slip on the chain plates during transportation.

[0005] Therefore, the existing spiral chain plate elevator has the problem of incomplete contact between the material and the bottom chain plate, and the problem of small contact surface with the chain plate, which makes the friction force on the material small and causes the material to easily slide on the chain plate during the conveying process. To this end, we propose a spiral chain plate elevator and a method for using the same. Summary of the invention

[0015] Preferably, there is always a gap between two adjacent sleeve plates in the vertical direction.

[0016] A method for using a spiral chain plate elevator comprises the following steps: S1. When in use, place the material on the chain plate assembly, and the chain plate assembly transports the material; 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. 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; 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.

[0017] The present invention has the following beneficial effects: 1. The present invention is provided with a structure of a guide plate and a sleeve plate, and the guide plate is used to elastically support the sleeve plate. When the material is placed above the anti-skid pad on the sleeve plate, the material is pressed downward by the anti-skid pad and the sleeve plate that it contacts, so that the placement height of the material on the chain plate assembly is reduced, and the material and the bottom that originally could not contact the chain plate assembly are brought into contact. After the material is brought into contact with more chain plate assemblies, 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 slide on the chain plate during the material transportation process, and the material transportation is more stable.

[0018] 2. The present invention is provided with a guide seat, a guide plate, an arc-shaped chute, and an arc-shaped abutment structure. When the material is placed on the anti-skid pad, the material will generate lateral pressure on the anti-skid pad, the sleeve plate, and the guide plate, causing the guide plate to deflect on the guide seat, causing the anti-skid pad and the sleeve plate to rotate synchronously. After the anti-skid pad rotates, it will contact the bottom of the material with a larger area, so that the material and the anti-skid pad are in full contact, which greatly increases the friction area of ​​the material, thereby increasing the friction force of the elevator on the material, so that during the material conveying process, the material will not slide on the chain plate, and the material conveying 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 abutment allows the guide plate in the device to automatically reset after the material conveying is completed.

[0019] 3. The present invention sets a clamping rod on the guide plate in the inner cavity. When the material presses the anti-skid pad and the sleeve plate downward, the clamping rod will gradually contact the anti-skid pad. Finally, the clamping rod will support the material through the anti-skid pad. The clamping rod deforms the anti-skid pad. The greater the pressure of the material on the clamping rod, the greater the deformation amplitude of the anti-skid pad caused by the clamping rod. The deformation part of the anti-skid pad becomes uneven, which increases the friction coefficient of the deformation part of the anti-skid pad and the friction force of the anti-skid pad on the material, thereby improving the anti-skid ability of the chain plate assembly. The deformation amplitude of the anti-skid pad caused by the clamping rod is affected by the weight of the material. The lighter the material, the smaller the deformation amplitude of the anti-skid pad or even no deformation occurs. This has a good protective effect on the anti-skid pad and makes the anti-skid pad not easy to be damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0024] See also Figure 1 - Fig.10As shown, a spiral chain plate elevator comprises a base 1, a frame 2 fixedly mounted above the base 1, a driving device 3 fixedly mounted at a lower corner of 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 comprises 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; The bottom of the guide plate 53 is provided with an arc-shaped slide groove 8 matched with the guide seat 52 . The guide seat 52 is movably arranged below the arc-shaped slide groove 8 . The guide plate 53 rotates above the guide seat 52 . The guide plate 53 can reciprocate on the guide seat 52 .

[0025] A plurality of arc-shaped abutting shafts 6 are elastically connected to both sides of the guide seat 52, and the arc-shaped abutting shafts 6 abut against the inner wall of the arc-shaped slide groove 8; the number of the arc-shaped abutting shafts 6 on both sides of the guide seat 52 is the same and corresponds to each other. When no external force is applied, the arc-shaped abutting shafts 6 on both sides of the guide seat 52 have the same supporting force on the guide plate 53. The pressure exerted 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 the pressure of the material is removed, the arc-shaped abutting shafts 6 reset the guide plate 53 on the guide seat 52 under elastic support.

[0026] 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 moves toward the guide plate 53 after being subjected to the pressure of the material.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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 partially contact the bottom chain plate. The chain plate is located directly below the material and cannot fully contact the material, resulting in a small contact area between the material and the chain plate, which makes the friction force on the material small. This makes it easy for the material to slip on the chain plate 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 chain plate assembly 5 can increase the contact area with the material by rotating. By setting the guide seat 52, the guide plate 53, the arc chute 8, and the arc abutment 6 structure, when the material is placed on the anti-skid pad 55, the material will generate lateral pressure on the anti-skid pad 55, the sleeve 54 and the guide plate 53, so that the guide plate 53 deflects on the guide seat 52, and the anti-skid pad 55 and the sleeve 54 rotate synchronously. After the anti-skid pad 55 rotates, a larger area of ​​contact will be made with the bottom of the material, so that the material and the anti-skid pad 55 are in full contact, which greatly increases the friction area of ​​the material, thereby increasing the friction force of the elevator on the material, so that the material will not slide on the chain plate during the material transportation process, and the material transportation is more stable. The setting of the arc chute 8 facilitates the directional rotation of the guide plate 53, and the setting of the arc abutment 6 makes the guide plate 53 in the device automatically reset after the material transportation is completed.

[0031] In order to further improve the anti-skid 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-skid pad 55 and the sleeve plate 54 downward, the clamping rod 10 will gradually contact the anti-skid pad 55. Finally, the clamping rod 10 will support the material through the anti-skid pad 55. The clamping rod 10 causes the anti-skid pad 55 to deform. The greater the pressure of the material on the clamping rod 10, the greater the deformation amplitude of the anti-skid pad 55 caused by the clamping rod 10. The deformation part of the anti-skid pad 55 becomes uneven, which increases the friction coefficient of the deformation part of the anti-skid pad 55 and increases the friction force of the anti-skid pad 55 on the material, thereby improving the anti-skid ability of the chain plate assembly 5. The deformation amplitude of the anti-skid pad 55 caused by the clamping rod 10 is affected by the weight of the material. The lighter the material, the smaller the deformation amplitude of the anti-skid pad 55 or even no deformation occurs, which plays a good protective role on the anti-skid pad 55 and makes the anti-skid pad 55 not easy to be damaged. The surface of the anti-slip pad 55 is a flat structure and is not easily damaged.

[0032] A thread groove 11 is formed at the end of the guide plate 53 , and the inner thread of the thread groove 11 is connected to a limit rod 12 . A limit opening 13 is formed on the side wall of the sleeve plate 54 , and the limit rod 12 is located inside the limit opening 13 .

[0033] In order to prevent the sleeve plate 54 from falling off the guide plate 53, a limit rod 12 is installed on the guide plate 53, and the limit rod 12 is stuck in the limit opening 13. When the sleeve plate 54 moves on the guide plate 53, the limit rod 12 limits the sleeve plate 54 to prevent the sleeve plate 54 from falling off the guide plate 53.

[0034] A baffle plate 14 is fixedly disposed below the end of the sleeve plate 54 , and the baffle plate 14 is located at the end of the guide seat 52 .

[0037] After the material is conveyed, in order to facilitate the arc-shaped shaft 6 to reset the guide plate 53, the design uses a first spring 16 to support the retaining ring 17, pushing the arc-shaped shaft 6 to move outside the arc-shaped slot 15, and the arc-shaped shaft 6 pushes the guide plate 53 to reset.

[0038] Among them, a limit shaft 27 is fixedly set on the deep inner wall of the arc slot 15, and the limit shaft 27 is located inside the first spring 16. A limit hole 18 is opened at one end of the arc-shaped abutment shaft 6 extending into the arc slot 15, and the limit shaft 27 is movably set inside the limit hole 18.

[0039] In order to prevent the first spring 16 from twisting in the arc-shaped slot 15, a limiting shaft 27 is provided in the first spring 16 to prevent the first spring 16 from twisting. The limiting shaft 27 moves in the limiting hole 18 to limit the arc-shaped abutting shaft 6, so that the arc-shaped abutting shaft 6 moves more smoothly in the arc-shaped slot 15.

[0040] Among them, a plurality of inner grooves 19 are opened above the guide plate 53, and a second spring 20 is arranged inside each inner groove 19.

[0041] In order 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 in the limiting sleeve 21.

When in use, place the material on the chain plate assembly 5, and the chain plate assembly 5 transports the material; 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; 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; S4.
