Description

Technical Field

[0001] The present invention relates to the technical field of double-speed chain, and particularly relates to a liftable double-layer double-speed chain conveying system. Background Art

[0002] A double-speed chain conveyor line generally refers to an assembly line composed of double-speed chains, abbreviated as a double-speed line. A double-speed line is generally assembled from a guide rail, a support frame, a double-speed chain, a motor, a sprocket rod, a double-speed sprocket, a stopper, and a tooling plate;

[0003] During the use of the double-speed chain, since the double-speed chain keeps moving, when supporting heavy objects, it will also increase the friction between the double-speed chain and the support frame. Therefore, lubrication during the use of the double-speed chain is particularly important; usually, in order to lubricate each position of the double-speed chain more precisely, it is necessary to manually apply oil to the surface of the chain regularly with an oil can or a brush, and observe the lubrication condition of the surface of the double-speed chain in time during the lubrication process. However, this lubrication method has low efficiency. Summary of the Invention

[0004] Technical Problem to be Solved

[0005] In view of the above-mentioned drawbacks of the prior art, the present invention provides a liftable double-layer double-speed chain conveying system, which can effectively solve the problem that in the prior art, in order to lubricate each position of the double-speed chain more precisely, it is necessary to manually apply oil to the surface of the chain regularly with an oil can or a brush, and observe the lubrication condition of the surface of the double-speed chain in time during the lubrication process. However, this lubrication method has low efficiency.

[0006] Technical Solution

[0007] To achieve the above object, the present invention is realized through the following technical solutions:

[0008] The present invention provides a liftable double-layer double-speed chain conveying system, including a frame. An elevator platform is installed inside the frame in a liftable manner. A double-speed chain is arranged on the elevator platform. One end of the elevator platform is used to be docked with two groups of double-speed chain conveyor lines distributed vertically and horizontally respectively. A lifting motor is fixedly installed at the bottom of the frame. Lifting drag chains for driving the elevator platform to move up and down are respectively arranged on both sides inside the frame. Both sides of the lifting motor are respectively connected to the lifting drag chains in a transmission manner;

[0009] The system further includes a plurality of double-speed chain transmission components. Every two of the double-speed chain transmission components are fixedly installed on one side of each end of the elevator platform. Every two of the double-speed chain transmission components are used to drag both ends of a double-speed chain. A conveying motor for driving the double-speed chain transmission component is fixedly installed on the side surface of each double-speed chain transmission component. An installation box is detachably installed below the double-speed chain transmission component. The inside of the installation box is used to lubricate and clean the double-speed chain.

[0010] Further, an output shaft is provided on the conveying motor. A driving gear and a first limiting roller are rotatably mounted on the speed chain transmission assembly. The output shaft passes through the center of the driving gear to drive the driving gear to rotate. The speed chain is sleeved on the driving gear, and the first limiting roller is used to limit the moving position of the speed chain.

[0011] Further, a partition is fixedly installed inside the installation box. The partition divides the interior of the installation box into a cleaning space and a lubricating space.

[0012] Further, a limiting gear is rotatably mounted inside the lubricating space. The limiting gear is used to guide the movement of the speed chain. The limiting gear is located directly below the driving gear. A second limiting roller is rotatably mounted on the side away from the middle of the lifting table between the limiting gear and the driving gear. The second limiting roller is used to adjust the conveying angle of the speed chain. The second limiting roller is located directly below the first limiting roller.

[0013] Further, a storage box is slidably mounted up and down at the bottom of the lubricating space. The storage box is used to store lubricating grease. A brush roller is rotatably mounted on the side of the limiting gear facing the middle of the lifting table. Multiple rows of bristles are arranged in a circular array on the outer peripheral surface of the brush roller. The bristles are used to clean the excess lubricating grease on the speed chain.

[0014] Further, a transmission belt is sleeved on the output shaft. The other end of the transmission belt is sleeved on one end of the brush roller. The output shaft drives the brush roller to rotate through the transmission belt.

[0015] Further, a cross plate is provided on the side of the partition away from the limiting gear. An installation through hole is provided on the cross plate. A blower is fixedly installed inside the installation through hole. The blower is used to absorb the residual dust or debris on the speed chain. A filter box for collecting dust and debris is provided below the blower. The filter box is detachably connected to the bottom of the installation box.

[0016] Further, the partition includes an inclined portion at the upper end and a vertical portion at the lower end. The inclined portion is used to guide the dust or debris on the speed chain to move obliquely downward.

[0017] Further, it further includes a blocking cylinder. The blocking cylinder is fixedly installed at both ends of the lifting table. The blocking cylinder is used to control the moving position of the material.

[0018] Beneficial Effects

[0019] The technical solution provided by the present invention has the following beneficial effects compared with the known public technologies:

[0020] 1. In the present invention, a lifting motor is provided in the middle below the frame, and lifting drag chains are respectively arranged on both sides of the lifting motor. When it is necessary to adjust the up and down height of the lifting table and dock it with two sets of double-speed chain conveyor lines with different up and down distributions at different heights, the lifting motor rotates to conveniently drive the lifting drag chains to move, so that the height of the lifting table can be adjusted conveniently. Compared with the traditional hydraulic drive, there is no need to regularly replace hydraulic oil, seals or clean the oil circuit, reducing the downtime and maintenance costs. Controlled by a servo motor or a stepper motor, a positioning accuracy of millimeter level or even micron level can be achieved. In addition, by arranging an installation box below the double-speed chain transmission component, during the transmission process of the lifting drag chain, the double-speed chain can be conveniently lubricated and cleaned, making the maintenance method of the double-speed chain more convenient.

[0021] 2. In the present invention, by arranging a partition inside the installation box, the interior of the installation box can be divided into a cleaning space and a lubricating space. Before lubricating the double-speed chain, the double-speed chain is first cleaned, which can reduce the sundries on the surface of the double-speed chain and make the lubricating grease more evenly attached to the double-speed chain. By arranging a second limiting roller between the limiting gear and the driving gear, the moving direction of the double-speed chain can be restricted, causing the double-speed chain to bend during movement, so that the remaining sundries or dust on the double-speed chain can be exposed and can be more easily cleaned off.

[0022] 3. In the present invention, a storage box is arranged below the installation box for storing lubricating grease. During the movement of the double-speed chain, the double-speed chain will move into the interior of the storage box for lubrication. When the double-speed chain moves out of the storage box, the brush on the brush roller can dial down the excess lubricating grease from the double-speed chain, and at the same time, the brush can also make the lubricating grease attached to the double-speed chain more evenly distributed. In addition, since the brush roller rotates synchronously with the output shaft through a transmission belt, there is no need to additionally set a driving device. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. 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.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] For this reason, the embodiments of the present invention provide a liftable double-speed chain conveying system, the purpose of which is at least that by arranging a mounting box 6 below the double-speed chain drive assembly 5, during the transmission of the lifting drag chain 11, the double-speed chain 21 can be lubricated and cleaned conveniently, and the maintenance method of the double-speed chain 21 can be made more convenient.

[0038] Embodiment: A liftable double-speed chain conveying system, as Figure 1 - Figure 4As shown, it includes a frame 1, a lifting platform 2 is installed inside the frame 1 for lifting, a double-speed chain 21 is arranged on the lifting platform 2, one end of the lifting platform 2 is used to dock with two groups of double-speed chain conveyor lines distributed up and down, a lifting motor 12 is fixedly installed at the bottom of the frame 1, and lifting drag chains 11 (referring to mechanical transmission chains or synchronous chains) for driving the lifting platform 2 to move up and down are respectively arranged on both sides of the frame 1, and both sides of the lifting motor 12 are respectively connected to the lifting drag chains 11 for transmission;

[0039] It also includes multiple speed chain transmission assemblies 5, each two of which are fixedly mounted on one side of the two ends of the lifting platform 2, and each two of which are used to drag the two ends of a speed chain 21. A conveying motor 3 for driving the speed chain transmission assembly 5 is fixedly mounted on the side of the speed chain transmission assembly 5, and an installation box 6 is detachably mounted below the speed chain transmission assembly 5, and the interior of the installation box 6 is used to lubricate and clean the speed chain 21.

[0040] In the present invention, a lifting motor 12 is arranged in the lower middle part of the frame 1, and a lifting drag chain 11 is respectively arranged on both sides of the lifting motor 12. When it is necessary to adjust the upper and lower heights of the lifting platform 2 to connect with two groups of double-speed chain conveyor lines distributed up and down at different heights, the lifting drag chain 11 can be conveniently driven to move by the rotation of the lifting motor 12, so that the height of the lifting platform 2 can be conveniently adjusted. Compared with the traditional hydraulic drive, there is no need to regularly replace the hydraulic oil, seals or clean the oil circuit, thereby reducing downtime and maintenance costs. Through the control of the servo motor or stepper motor, the positioning accuracy of millimeter level or even micron level can be achieved; in addition, by arranging the installation box 6 below the double-speed chain transmission assembly 5, the double-speed chain 21 can be conveniently lubricated and cleaned during the transmission process of the lifting drag chain 11, so that the maintenance method of the double-speed chain 21 can be more convenient.

[0041] Furthermore, if Figure 4 and Figure 5 As shown, the conveying motor 3 is provided with an output shaft 31, and the speed chain transmission assembly 5 is rotatably installed with a driving gear 51 and a first limiting roller 52. The output shaft 31 passes through the center of the driving gear 51 to drive the driving gear 51 to rotate, and the speed chain 21 is sleeved on the driving gear 51, and the first limiting roller 52 is used to limit the moving position of the speed chain 21.

[0042] Among them, by setting a driving gear 51 on the double-speed chain transmission assembly 5, the double-speed chain 21 can be driven accurately. At the same time, a first limiting roller 52 is set on the side of the driving gear 51, which can conveniently limit the moving position of the double-speed chain 21 and ensure that the double-speed chain 21 is meshed and driven with the driving gear 51.

[0043] Further, as shown in Figure 5 and Figure 6 , a partition plate 63 is fixedly installed inside the installation box 6. The partition plate 63 divides the interior of the installation box 6 into a cleaning space and a lubricating space. A limiting gear 61 is rotatably installed inside the lubricating space. The limiting gear 61 is used to guide the movement of the double-speed chain 21. The limiting gear 61 is located directly below the driving gear 51. A second limiting roller 62 is rotatably installed on the side away from the middle of the lifting platform 2 between the limiting gear 61 and the driving gear 51. The second limiting roller 62 is used to adjust the conveying angle of the double-speed chain 21. The second limiting roller 62 is located directly below the first limiting roller 52.

[0044] Among them, by arranging the partition plate 63 inside the installation box 6, the interior of the installation box 6 can be divided into a cleaning space and a lubricating space. Before lubricating the double-speed chain 21, the double-speed chain 21 is first cleaned, which can reduce the debris on the surface of the double-speed chain 21 and make the lubricating grease more evenly attached to the double-speed chain 21. By arranging the second limiting roller 62 between the limiting gear 61 and the driving gear 51, the moving direction of the double-speed chain 21 can be restricted, causing the double-speed chain 21 to bend during movement, so that the remaining debris or dust on the double-speed chain 21 can be exposed and can be more easily cleaned off.

[0045] Further, as shown in Figure 6 and Figure 7 , a storage box 64 is slidably installed up and down at the bottom of the lubricating space. The storage box 64 is used to store lubricating grease. A brush roller 66 is rotatably installed on the side of the limiting gear 61 facing the middle of the lifting platform 2. Multiple rows of bristles are arranged in a circular array on the outer peripheral surface of the brush roller 66. The bristles are used to clean the excess lubricating grease from the double-speed chain 21. A transmission belt 32 is sleeved on the output shaft 31. The other end of the transmission belt 32 is sleeved on one end of the brush roller 66. The output shaft 31 drives the brush roller 66 to rotate through the transmission belt 32.

[0046] Among them, by arranging the storage box 64 below the installation box 6 to store the lubricating grease, during the movement of the double-speed chain 21, the double-speed chain 21 will move into the storage box 64 for lubrication. When the double-speed chain 21 moves out of the storage box 64, the bristles on the brush roller 66 can scrape the excess lubricating grease off the double-speed chain 21 downward. At the same time, the bristles can also make the lubricating grease attached to the double-speed chain 21 more evenly distributed. In addition, since the brush roller 66 rotates synchronously with the output shaft 31 through the transmission belt 32, there is no need to set up an additional driving device.

[0047] Further, as shown in Figure 6 and Figure 7As shown, on the side of the partition plate 63 away from the limit gear 61, there is a cross plate 631. An installation through hole is provided on the cross plate 631, and a blower 632 is fixedly installed inside the installation through hole. The blower 632 is used to absorb the dust or debris remaining on the double-speed chain 21. Below the blower 632, there is a filter box 65 for collecting the dust and debris. The filter box 65 is detachably connected to the bottom of the installation box 6; the partition plate 63 includes an inclined part at the upper end and a vertical part at the lower end. The inclined part is used to guide the dust or debris on the double-speed chain 21 to move downward obliquely.

[0048] Among them, by arranging the cross plate 631 on the side of the partition plate 63 and installing the cross plate 631 at the connection between the cleaning part and the vertical part, when adsorbing the debris or dust on the surface of the double-speed chain 21, the inclined part of the partition plate 63 can guide the dust or debris, so that the dust or debris can be smoothly sucked into the interior of the filter box 65 by the blower 632.

[0049] Further, as Figure 1 shown, it further includes a blocking cylinder 4. The blocking cylinder 4 is fixedly installed at both ends of the lifting table 2. The blocking cylinder 4 is used to control the moving position of the material, which can more conveniently limit the material placed on the lifting table 2 and convey the material more accurately.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
