Description

Technical Field

[0001] The present invention relates to the technical field of multi-process chamber transportation, and specifically provides a conveying device for achieving long-distance cross-sealed area transmission in a narrow space. Background Art

[0002] In existing article conveying systems, especially in the fields of industrial production and automation, long-distance article conveyance usually relies on mechanical devices such as cylinder pushing or scissor hinges. However, these traditional conveying technologies have significant limitations in practical applications. Firstly, the effective length of cylinder pushing is limited by the cylinder stroke, making it difficult to achieve long-distance article conveyance. In addition, the thrust during cylinder pushing is difficult to precisely control, easily resulting in unstable positions or increased errors of the conveyed objects.

[0003] Although the scissor hinge type conveying device can achieve a certain distance of pushing, due to its complex structure and susceptibility to friction, it is often difficult to ensure the smoothness and uniformity during the pushing process. Especially when crossing multiple process chambers or sealed areas, the application of this device becomes more difficult. The connection and deployment process of the scissor hinge is complex, not only increasing the maintenance cost but also possibly leading to frequent equipment failures. In addition, these devices are usually large in size, occupy a lot of space, and are not suitable for application scenarios in narrow spaces.

[0004] Therefore, those skilled in the art provide a conveying device for achieving long-distance cross-sealed area transmission in a narrow space to solve the problems raised in the above background art. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a conveying device for achieving long-distance cross-sealed area transmission in a narrow space, solving the problem that the conveying device in the prior art is too large in size to achieve long-distance cross-sealed area transmission in a narrow space.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A conveying device for achieving long-distance cross-sealed area transmission in a narrow space includes a processing chamber, on one side of the inner wall of the processing chamber is fixedly connected a chain chamber, on one side of the processing chamber is installed a motor, the output end of the motor is fixedly connected to a driving gear, on one side of the processing chamber is provided a flap valve, a one-way bending chain is slidably connected in a spiral shape on the inner wall of the chain chamber, on one side of the one-way bending chain is rotatably connected a cross plate, multiple chain tracks are arranged on the inner wall of the processing chamber, a cleaning component is arranged on the inner wall of the chain chamber, and an adjusting component is arranged on the inner wall of the cross plate;

[0007] The one-way bending chain includes outer chain plates, on the adjacent sides of two outer chain plates are provided rotating shafts, on both sides of the inner wall of the rotating shafts are provided inner chain plates, and one side of the rotating shaft is a right-angle side.

[0008] Preferably, the cleaning assembly includes a mounting block, a plurality of the mounting blocks are fixedly connected to one side of the inner wall of the chain bin, a spring is fixedly connected to the inner wall of the mounting block, and a brush plate is slidably connected to one side of the inner wall of the mounting block.

[0009] Preferably, the adjustment component includes an electric push rod, which is fixedly connected to the inner wall of the cross plate, the output end of the electric push rod is fixedly connected to a displacement block, the top side of the displacement block is fixedly connected to a push plate, and the inner wall of the displacement block is provided with a sliding block.

[0010] Preferably, the cross plate is slidably connected to the inner wall of the pushing plate, and the one-way bending chain is slidably connected to the inner wall of the chain track.

[0011] Preferably, the power gear is meshingly connected to the one-way curved chain.

[0012] Preferably, the sliding block is slidably connected to the outer wall of the cross-plate, and the outer wall of the cross-plate is provided with a limiting groove.

[0013] Preferably, a plurality of the brush plates are slidably connected to the upper and lower ends of the unidirectional bending chain.

[0014] Preferably, the unidirectional bending chain is composed of multiple sections of outer chain plates, a rotating shaft, and inner chain plates.

[0015] Working principle: When objects are transported over long distances through this conveying device, the materials first enter the inner wall of the processing bin at the top of the chain track, and then the motor is turned on. The power output of the motor drives the power gear and the one-way curved chain to engage with each other, and then the one-way curved chain is pushed out from the vortex placement groove inside the chain bin to contact the object through the push plate, and the displacement range of the object is controlled according to the control motor.

[0016] When an object enters the processing bin at one end from the processing bin at the other end, for different lengths of the spanning space, the electric push rod can be started to control the displacement block to extend as a whole, and in the process of crossing the spanning space, the outer chain pieces that make up the one-way bending chain have a right-angled edge design at the bottom. Therefore, with the support of the chain track, the one-way bending property of the one-way bending chain can be utilized. In the process of continuing to move forward beyond the chain track, the one-way bending chain can be pushed forward horizontally without bending downward, thereby achieving the goal of crossing the space that needs to be closed.

[0017] When the one-way bending chain is recovered, the one-way bending of the one-way bending chain can make the chain coiled in the spiral chain bin. The structure of the spiral chain bin enables the longer one-way bending chain to be stored in a smaller space, ensuring the maximum possible pushing and retracting length in a small space.

[0018] During the process of recycling or extrapolation, the unidirectional bending chain will pass through the contact positions of the two side brush plates, thereby achieving the cleaning and maintenance effect on the unidirectional bending chain.

[0019] The present invention provides a transmission device for achieving long-distance crossing of a closed area in a narrow space. It has the following beneficial effects:

[0020] 1. Through the design of the unidirectional bending chain and the spiral chain bin, the device realizes long-distance transmission in a narrow space. The chain can maintain a horizontal state, accurately control the displacement of the object, and is especially suitable for scenarios of crossing closed areas, effectively improving the transmission efficiency and space utilization rate.

[0021] 2. The device of the present invention uses a chain track to support the unidirectional bending chain to ensure the stability and direction control of the chain during operation. The flap valve ensures the sealing of the processing bin and prevents external interference, and is especially suitable for application scenarios with high requirements for the transmission environment, enhancing the safety of transportation.

[0022] 3. The cleaning component equipped with the present invention cleans the surface of the chain through brush plates, removes dust and dirt, and prolongs the service life of the chain. The continuous pressure provided by the spring ensures the cleaning effect, effectively reduces the maintenance requirements and costs, and improves the operation efficiency and stability of the system.

[0023] 4. The cross plate of the present invention is equipped with an adjustment component, which can adjust the length of the cross space as needed. The electric push rod accurately controls the displacement, adapts to different transmission distance requirements, improves the flexibility and application range of the equipment, helps to optimize the production line layout and reduces the adjustment time.

Specific embodiments

[0031] The technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0032] Embodiment:

[0033] Please refer to the attached Figure 1 - attached Figure 2 , an embodiment of the present invention provides a conveying device for realizing long-distance cross-sealed area transmission in a narrow space, including a processing bin 1, a chain bin 2 is fixedly connected to one side of the inner wall of the processing bin 1, a motor 4 is installed on one side of the processing bin 1, the output end of the motor 4 is fixedly connected to a driving gear 3, and the driving gear 3 is meshed with a one-way bending chain 6.

[0034] Specifically, the motor 4 outputs power to drive the driving gear 3 and the one-way bending chain 6 to be meshed, and then pushes the one-way bending chain 6 out of the spiral placement groove inside the chain bin 2 to contact the object through the pushing plate 8, and the displacement range of the object is controlled according to the control of the motor 4.

[0035] This design is especially suitable for application scenarios where objects need to be conveyed in narrow channels or between multi-process cabins. Through the one-way bending characteristic of the chain and the precise control system, the device can ensure the sealing performance while realizing stable long-distance item transmission.

[0036] Please refer to the attached Figure 1 , attached Figure 2 , attached Figure 6 , a flap valve 5 is arranged on one side of the processing bin 1, and the flap valve 5 is used to control the sealing between the processing bins 1. When the flap valve 5 is lifted, there will be a cross space between multiple chain tracks 9. The inner wall of the chain bin 2 is slidably connected with a one-way bending chain 6 in a spiral shape, one side of the one-way bending chain 6 is rotatably connected with a cross plate 7, and multiple chain tracks 9 are arranged on the inner wall of the processing bin 1;

[0037] Specifically, the structural design of the unidirectional bending chain 6 allows the chain to bend in only one direction. This feature ensures that the chain remains horizontal during the conveying process and does not sag downward. One side of the chain is connected to a cross plate 7, through which the conveyance of items across the enclosed area can be achieved. The inner wall of the processing bin 1 is provided with multiple chain tracks 9, and the chain tracks 9 provide the path and support for the chain to run, ensuring the stability and direction control of the chain during operation.

[0038] The unidirectional bending of the unidirectional bending chain 6 enables the chain to be coiled in the spiral chain bin 2. The structure of the spiral chain bin 2 allows the relatively long unidirectional bending chain 6 to be stored in a smaller space, ensuring the maximum possible length of the pushing and telescoping within a narrow space.

[0039] Please refer to the appendix Figure 5 , the unidirectional bending chain 6 is composed of multiple outer link plates 16, rotating shafts 17, and inner link plates 18. Rotating shafts 17 are provided on the adjacent sides of two outer link plates 16, and inner link plates 18 are provided on both sides of the inner wall of the rotating shafts 17. One side of the rotating shaft 17 is a right-angle side. The cross plate 7 is slidably connected to the inner wall of the pushing plate 8, and the unidirectional bending chain 6 is slidably connected to the inner wall of the chain track 9.

[0040] Specifically, the inwardly bent part of the outer link plate 16 adopts a concentric circle design to ensure free inward bending, and the outward part adopts a tangent right-angle side design to ensure that it cannot bend outward.

[0041] Please refer to the appendix Figure 2 - appendix Figure 3 , the inner wall of the chain bin 2 is provided with a cleaning component. The cleaning component includes mounting blocks 10. Multiple mounting blocks 10 are fixedly connected to one side of the inner wall of the chain bin 2. A spring 11 is fixedly connected to the inner wall of the mounting block 10. A brush plate 12 is slidably connected to one side of the inner wall of the mounting block 10. Multiple brush plates 12 are slidably connected to the upper and lower ends of the unidirectional bending chain 6.

[0042] Specifically, during the process of chain recycling or outward pushing, at the contact position of the unidirectional bending chain 6 with the brush plate 12, the bristles on the brush plate 12 can effectively remove dust, dirt, and other impurities on the surface of the chain. The elastic action of the spring 11 ensures that the brush plate 12 always adheres tightly to the chain, providing continuous cleaning pressure, thereby ensuring the cleaning effect.

[0043] This design can not only keep the chain clean, reduce chain wear caused by dust and impurities, but also extend the service life of the chain. By maintaining the good condition of the chain, the operating efficiency and stability of the entire conveying system are improved, especially during long-term operation or in a harsh environment

[0044] Please refer to the appendix Figure 4, an adjusting assembly is provided on the inner wall of the cross plate 7. The adjusting assembly includes an electric push rod 13 which is fixedly connected to the inner wall of the cross plate 7. The output end of the electric push rod 13 is fixedly connected with a displacement block 14. One side of the top of the displacement block 14 is fixedly connected with a pushing plate 8. A sliding block 15 is arranged inside the displacement block 14. The sliding block 15 is slidably connected to the outer wall of the cross plate 7, and a limiting groove is arranged on the outer wall of the cross plate 7.

[0045] Specifically, for different lengths of the cross space, the displacement block 14 can be controlled to extend integrally by starting the electric push rod 13. The limiting groove between the sliding block 15 and the cross plate 7 can ensure the stability of the displacement block 14 sliding in the chain track 9.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
