Description

Technical Field

[0001] This utility model belongs to the field of transportation equipment technology, and specifically relates to a chain machine with an externally mounted roller lifting and transfer device. Background Technology

[0002] With the rapid development of new energy vehicles, energy storage systems, and portable electronic devices, the demand for secondary batteries such as lithium-ion batteries has exploded. The battery manufacturing process requires placing lithium battery packs onto pallets for transport, and subsequently connecting them with packaging machines to complete the packaging of the lithium batteries.

[0003] In current lithium battery raw material packaging, packaging machines need to pack the battery raw materials into ton bags. These ton bags are then placed on pallets and transported to designated storage locations via a chain conveyor and a chain conveyor. The chain conveyor works in conjunction with the packaging machine to transport the packaged battery ton bags. However, the pallets need to make a 90° turn during transport, resulting in a mismatch between the conveyor and chain conveyor heights; the conveyor is lower than the chain conveyor. Furthermore, the space between the powered ends of the packaging machine and the conveyor is very limited. In practice, only a short powered conveyor can be placed in between to support the pallet, leading to insufficient space. Therefore, a lifting and transfer device is needed to extend the powered section of the chain conveyor, ensuring the pallet can always be supported and effectively solving the space and cost issues. Thus, a transition lifting and transfer device is required between the chain conveyor and the conveyor to rotate the pallet on the chain conveyor 90° and transfer it to the conveyor for further transport.

[0004] In the actual processing and production process, the transition lifting and transfer device includes a non-powered conveyor section and a lifting device. The non-powered conveyor section is responsible for receiving the pallets conveyed by the chain conveyor, and the lifting device is responsible for changing the height of the pallets to match the height of the conveyor, so that the pallets can be connected with the subsequent conveyors, thereby completing the transfer of the pallets from the packaging machine to the conveyor.

[0005] However, such transition devices occupy a large space, have a complex structure, are costly, and are prone to interference due to space constraints, which is detrimental to the transfer and transport of pallets and results in low work efficiency. Therefore, in the field of lithium battery transport, there is a need to develop a device that is compact in structure, occupies little space, is easy to install, and is less prone to interference during the transport and transfer process. Utility Model Content

[0006] This utility model proposes an externally mounted roller lifting and transfer device for chain conveyors, which solves the problems of existing lifting and transfer devices in transferring battery trays from packaging machines to conveyors, such as complex structure, large size, difficulty in installation under insufficient space, and easy interference with roller conveyors.

[0007] The technical solution of this utility model is implemented as follows:

[0008] The chain conveyor is equipped with an externally mounted roller lifting and transfer device, which includes a frame, a lifting frame movably connected to the top of the frame, and two cylinders installed at the bottom of the frame. The piston rods of the two cylinders are connected to the lifting frame in a transmission manner, and the cylinders push the lifting frame to move up and down.

[0009] The top of the lifting frame is rotatably connected to several parallel and spaced rollers. A motor is installed at the bottom of the lifting frame. A drive gear is fixedly fitted on the output shaft of the motor. Gears D are fixedly fitted on the same end of each roller. The drive gear and gears D are connected by several chains. The motor drives several rollers to rotate.

[0010] The top of the lifting frame has a groove, and several rollers are asymmetrically distributed on the left and right sides of the groove.

[0011] Through the above technical solution, the groove design ensures that when the entire lifting and transferring device works with the chain conveyor to carry the pallet, the chain of the chain conveyor is located in the groove, which does not interfere with the rotation of the rollers, thus not interfering with the transfer and transportation of the pallet. A single motor can synchronously drive the rotation of multiple rollers, thereby controlling the transfer of the pallet. Two cylinders work together to move the lifting frame up and down, allowing the lifting frame to flexibly adapt to the height of the chain conveyor and the conveyor, thereby transferring the pallet from the chain conveyor to the conveyor. The overall structure is compact, and the vertical structure results in a small footprint and easy installation.

[0012] Optionally, the top of the frame is rotatably connected to two parallel and spaced-apart rotating shafts, which are located below the lifting frame. The four bottom corners of the lifting frame are hinged to the ends of the two rotating shafts. The piston rod ends of the two cylinders are each hinged to two parallel and spaced-apart connecting plates, which are sleeved and fixed on the outside of the same rotating shaft.

[0013] Through the above technical solution, the rotating shaft is used to cooperate with the cylinder to drive the lifting frame to move up and down flexibly.

[0014] Optionally, bearing seats A are fitted onto both the left and right ends of the rotating shaft, and the bearing seats A are fixedly connected to the frame.

[0015] Through the above technical solution, bearing housing A can improve the stability of shaft rotation.

[0016] Optionally, each of the four bottom corners of the lifting frame is hinged with two parallel, spaced right-angle plates. The right-angle ends of the two right-angle plates are sleeved and fixed to the rotating shaft. One acute-angle end of the two right-angle plates is hinged to the bottom of the lifting frame, and the other acute-angle end of the two right-angle plates is set downwards. Two parallel, spaced connecting rods are movably connected between the two rotating shafts, and the end of each connecting rod is hinged to the acute-angle end of the right-angle plate that is set downwards.

[0017] Through the above technical solution, the cooperation between the right-angle plate and the connecting rod enables the two cylinders to drive the four corners of the lifting frame to move up and down synchronously, thereby improving the stability of the lifting frame's up and down movement.

[0018] Optionally, a drive shaft is rotatably connected to the bottom of the lifting frame, a driven gear is sleeved on the outside of the drive shaft, a chain A is sleeved and meshed between the driving gear and the driven gear, a gear A is rotatably connected to one end of the drive shaft, and the gear A and the gear D are connected by a number of chains.

[0019] Through the above technical solution, the drive shaft acts as a transition, transmitting the driving force of the motor to gears A and D, thereby causing the drum to rotate.

[0020] Optionally, gears B and C are rotatably connected to the side of the lifting frame, with gear C located between gear A and gear B. A chain B is fitted and meshed between gear A and gear B, and gear C meshes with the outer side of chain B.

[0021] A chain C is fitted between each pair of adjacent gears D. A chain C is not fitted between the gears D located at the left and right ends of the groove. A gear D located at one end of the groove is fitted with a chain D and engaged with gear B. A chain C located at the other end of the groove is fitted with gear A.

[0022] Through the above technical solution, the coordination between gears A, B, C, and D, and chains C and D, enables a single motor to simultaneously drive multiple rollers to rotate, resulting in a more compact structure, smaller footprint, and lower cost. Gear C is used to maintain tension on chain B.

[0023] Optionally, bearing seats B are fitted onto both ends of the drive shaft, and the bearing seats B are fixedly connected to the lifting frame.

[0024] Through the above technical solution, bearing housing B can improve the stability of the drive shaft rotation.

[0025] Optionally, limit switches are installed at both ends of one side of the lifting frame to sense the position of the tray.

[0026] Optionally, the frame is equipped with feet at the four bottom corners.

[0027] After adopting the above technical solution, the beneficial effects of this utility model are:

[0028] The lifting and transferring device of this invention has a compact structure, occupies little space, and is low in cost. It allows for free and flexible adjustment of the lifting frame height, thus flexibly matching the height of the chain conveyor and the conveyor. Without interference from the chain conveyor chains, it can receive pallets from the chain conveyor and turn the pallets 90°, while also matching the height of the conveyor. The rotation of multiple rollers requires only one motor to drive it. Using multiple chains and gears in coordination, it does not occupy additional space and does not interfere with the roller conveying, making it highly practical. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model embodiment discloses an externally mounted roller lifting and transfer device for chain machines.

[0038] Example

[0039] according to Figures 1 to 5 As shown, the chain machine is equipped with an externally mounted roller lifting and transfer device, which includes a frame 1. The top of the frame 1 is rotatably connected to two parallel and spaced rotating shafts 5. Bearing seats A14 are fitted on both the left and right ends of the rotating shafts 5, and the bearing seats A14 are fixedly connected to the frame 1.

[0040] A lifting frame 2 is mounted on the top of the frame 1, located above the rotating shaft 5. Several rollers 6 are rotatably mounted parallel to each other on the top of the lifting frame 2. A groove 3 is formed on the top of the lifting frame 2, increasing the distance between two rollers 6. One end of the lifting frame 2 is installed at the point where the pallet conveyed by the chain conveyor 25 needs to make a 90° turn. The initial height of the lifting frame 2 is lower than the height of the chain conveyor 25, and the conveying direction of the lifting frame 2 is at a 90° angle to the conveying direction of the chain conveyor 25.

[0041] Two right-angle plates 7 are hinged to each of the four corners of the bottom of the lifting frame 2. The two right-angle plates 7 are arranged in parallel and spaced apart. The right-angle ends of the two right-angle plates 7 are sleeved and fixed to the rotating shaft 5. One acute-angle end of the two right-angle plates 7 is hinged to the bottom of the lifting frame 2, and the other acute-angle end of the two right-angle plates 7 is set downward. Two parallel and spaced connecting rods 26 are arranged between the two rotating shafts 5. The connecting rods 26 are set at 90° with the rotating shaft 5. The two ends of each connecting rod 26 are respectively hinged to the acute-angle end of the right-angle plate 7 that is set downward.

[0042] Two cylinders 9 are mounted at the bottom of the frame 1. Each cylinder 9 has two parallel, spaced-apart connecting plates 8 hinged to its piston rod end. The ends of the two connecting plates 8 furthest from the cylinder 9 are fitted and fixed to the outside of the same rotating shaft 5. When the piston rod of the cylinder 9 extends, it drives the connecting plate 8 to rotate. Simultaneously, the connecting plate 8 drives the lifting frame 2 at this end to move upwards. At the same time, the connecting plate 8 drives the rotating shaft 5 to rotate. As the rotating shaft 5 rotates, it drives the connecting rod 26 to move horizontally via a right-angle plate 7. During this horizontal movement, the connecting rod 26 pushes the right-angle plate 7 at the other end. This right-angle plate 7 drives another rotating shaft 5 to rotate, and the rotation of this shaft 5 simultaneously drives the right-angle plate 7 to rotate, thus achieving the upward movement of the lifting frame 2 at the other end.

[0043] A motor 10 is installed at the bottom of the lifting frame 2, located between two cylinders 9. A drive gear 11 is mounted on the output shaft of the motor 10. A drive shaft 13 is rotatably connected to the bottom of the lifting frame 2. Bearing seats B15 are fitted at both ends of the drive shaft 13, and the bearing seats B15 are fixedly connected to the lifting frame 2. A driven gear 12 is fitted on the outer side of the drive shaft 13. A chain A20 meshes between the drive gear 11 and the driven gear 12. A gear A16 is rotatably connected to one end of the drive shaft 13. Gears B17 and C18 are rotatably connected to the side of the lifting frame 2. Gear C18 is located between gears A16 and B17. A chain B21 meshes between gears A16 and B17, and gear C18 meshes with the outer side of chain B21.

[0044] Gears D19 are fixedly fitted onto the same end of two adjacent rollers 6. Chains C22 mesh between adjacent gears D19. Chains C22 do not mesh between the two gears D19 located at the left and right ends of the groove 3. One gear D19 at one end of the groove 3 meshes with gear B17 via chain D23. One chain C22 at the other end of the groove 3 meshes with gear A16. The rotation of gear A16 can drive gear B17 to rotate via chain B21, and also drive roller 6 to rotate via the meshing chain C22. The rotation of gear B17 can drive the connected roller 6 to rotate via chain D23.

[0045] Limit switches 24 are installed at both ends of one side of the lifting frame 2 to sense the position of the tray. Support legs 4 are installed at the four corners of the bottom of the frame 1, and the upper ends of the support legs 4 are threaded to the bottom of the frame 1.

[0046] Working principle:

[0047] In this utility model, the lifting and transferring device is located below the chain machine 25. The conveying direction of the roller 6 of the lifting and transferring device is set at 90° with the conveying direction of the chain machine 25. One of the chains of the chain machine 25 is located in the groove 3 at the top of the lifting frame 2.

[0048] The lifting frame 2 is moved up and down by two cylinders 9 as follows: When the two cylinders 9 are activated, their piston rods extend. Simultaneously, the piston rods drive the rotating shaft 5 (which is fixedly connected to the connecting plate 8) to rotate via the connecting plate 8. This rotation of the shaft 5 causes the right-angle plate 7, which is fixedly connected to it, to rotate clockwise. As the right-angle plate 7 rotates, it simultaneously moves the end of the lifting frame 2 upwards and the connecting rod 26 horizontally. Simultaneously, the connecting rod 26 causes the right-angle plate 7, which is away from the piston rods of the cylinders 9, to rotate clockwise. This rotation of the right-angle plate 7 simultaneously drives the rotating shaft 5 to rotate synchronously and also causes the end of the lifting frame 2 to move upwards. Thus, the entire lifting frame 2 moves upwards. When the lifting frame 2 needs to move downwards, the piston rods of the cylinders 9 retract, and the above movements are reversed, thus achieving the downward movement of the lifting frame 2.

[0049] The process of motor 10 driving drum 6 to rotate is as follows: the output shaft of motor 10 drives the drive gear 11 to rotate, the drive gear 11 drives the driven gear 12 to rotate through chain A20, the driven gear 12 drives the transmission shaft 13 to rotate at the same time, the transmission shaft 13 drives the gear A16 to rotate during the rotation, the gear A16 drives the gear B17 and gear C18 to rotate through chain B21 during the rotation, the gear B17 drives the gear D19 (the gear D19 that meshes with chain D23) to rotate through chain D23 during the rotation, the gear D19 drives the adjacent gear D19 to rotate through chain C22, thereby realizing the rotation of drum 6. During its rotation, gear A16 drives the chain C22, which meshes with it, to rotate, thereby causing the remaining gear D19 and chain C22 to rotate, and thus the remaining rollers 6 to rotate. This achieves the technical effect of one motor 10 driving multiple rollers 6. Moreover, motor 10 is located at the bottom of lifting frame 2, which does not occupy the space of the entire device. The multiple chains that drive gear D19 are located on the side of lifting frame 2, which will not interfere with the movement of the rollers 6 conveying the pallets. The two cylinders 9 are located at the bottom of frame 1. Lifting frame 2 and frame 1 are distributed vertically, which will not occupy additional space. The entire device has a compact structure and does not occupy additional space. The transmission between multiple chains and multiple gears is also centrally and uniformly installed on the side of the entire device, which will not interfere with the subsequent conveying of the pallets by rollers 6.

[0050] When a pallet (containing battery packs) needs to be received from the packaging machine, two cylinders 9 drive the lifting frame 2 upward until it matches the height of the chain conveyor 25. As the lifting frame 2 moves upward to receive the pallet, the groove 3 is designed so that one of the chains of the chain conveyor 25 is precisely engaged in the groove 3, preventing interference between the chain of the chain conveyor 25 and the roller 6. The roller 6 of the lifting frame 2 can then smoothly receive the pallet. The motor 10 is then started, driving the roller 6 to rotate. After the roller 6 has conveyed the pallet to the point of disengagement from the chain conveyor 25, the two cylinders 9 reset, and the lifting frame 2 moves the pallet downward, matching its height to that of the conveyor, thus transferring the pallet onto the conveyor and completing the subsequent pallet transport.

[0051] Because the conveying direction of the roller 6 of the lifting frame 2 is set at 90° to the conveying direction of the chain conveyor 25, the 90° turn of the pallet is completed when the lifting frame 2 receives the pallet from the chain conveyor 25 and the pallet is detached from the chain conveyor 25. The lifting and transferring device in this utility model has a compact structure and occupies little space. It can not only carry the pallet from the chain conveyor 25, but also turn the pallet 90° without chain interference, and can also change the height to match and connect with the conveyor.
