Technical Field

[0001] The present invention relates to the technical field of cushion conveying, and particularly relates to a conveying device for high-speed rail cushion production. Background Art

[0002] High-speed rail, the full name of which is high-speed railway, is a railway system with high design standard grades and allows trains to run safely at high speeds. Its designed speed is usually between 250 km / h (inclusive) and 350 km / h (inclusive), and it operates EMU trains. The emergence of high-speed rail has greatly shortened the distance between cities, improved people's travel efficiency, and promoted regional economic development. High-speed rail cushions are the cushions provided for passengers under the seats of high-speed rail trains, mainly used to improve the riding comfort. High-speed rail cushions are usually made of materials such as fabrics, textiles or straw mats, and are filled with soft or elastic materials inside for passengers to sit and lie on. High-speed rail cushions mostly use plain weave fabrics or special fabrics, with a flat surface and not easy to accumulate dust. High-speed rail cushions are an important facility to enhance the passenger experience in high-speed rail services, and have the functions of comfort, cleanliness guarantee and basic services. The production of high-speed rail cushions includes multiple processing procedures, and a conveying device is required to convey the cushions and transport them to the designated processing area.

[0003] Most high-speed rail cushions have special-shaped structures. When conveying the cushions through a conveyor belt structure, it is inconvenient to fix the cushions. Moreover, the existing conveyor belt structure only has the function of conveying, with a single structural function, and the flexibility and versatility during use are relatively low. Summary of the Invention

[0004] Technical problems to be solved:

[0005] Aiming at the deficiencies of the prior art, the present invention provides a conveying device for high-speed rail cushion production. The negative pressure pump assembly extracts the air inside the negative pressure adsorption chamber of the conveying assembly through an air pipe. When the bottom of the cushion contacts the conveyor belt, the cushion is adsorbed and fixed by the negative pressure adsorption force of multiple groups of through holes. The distance between the first conveying assembly and the second conveying assembly is adjusted by the first adjustment assembly, and the conveying posture of the conveying device can be adjusted accordingly according to the position of the subsequent platform, improving the flexibility and versatility and solving the technical problems mentioned in the background art.

On the bidirectional lead screw, a first sliding seat and a second sliding seat are sleeved, and the sliding rod passes through the first sliding seat and the second sliding seat. Between the first sliding seat and the second sliding seat and the sliding rod, they are all slidably connected. When the second motor works, it drives the bidirectional lead screw at its one end to rotate, and then drives the first sliding seat and the second sliding seat to slide along the sliding rod, driving the first sliding seat and the second sliding seat to approach or move away from each other.

[0012] In a possible implementation, the first slide and the second slide are respectively located on both sides of the bidirectional lead screw. Both the first conveying assembly and the second conveying assembly include legs, and the legs are fixed to the outer side plates.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. A negative pressure adsorption chamber is formed between the outer side plate, the inner side plate of the conveying assembly of the present invention and the conveyor belt. When the cushion is conveyed, the negative pressure pump assembly extracts the air inside the negative pressure adsorption chamber through the air pipe, so that the negative pressure adsorption chamber is always in a negative pressure state, and then a negative pressure adsorption force is generated by multiple through holes on the conveyor belt.

[0034] In an embodiment of the present application, a conveying device for high-speed rail seat production is provided. The negative pressure pump assembly extracts the air inside the negative pressure adsorption chamber of the conveying component through the air pipe. When the bottom of the seat contacts the conveyor belt, the seat is adsorbed and fixed by the negative pressure adsorption force of multiple through holes. The distance between the first conveying component and the second conveying component is adjusted by the first adjusting component, and the conveying posture of the conveying device can be adjusted accordingly according to the position of the subsequent platform, improving flexibility and versatility, and solving the technical problems mentioned in the background art.

[0035] The technical solution in the embodiment of the present application is to solve the problems in the above background art, and the general idea is as follows:

[0036] Embodiment 1:

[0037] Please refer to Figures 1-10 , the present invention provides a technical solution: a conveying device for high-speed rail seat production, including a first conveying component 1 and a second conveying component 2. On both sides of the lower ends of the first conveying component 1 and the second conveying component 2, a first adjusting component 3 is provided. The first adjusting component 3 is used to adjust the distance between the first conveying component 1 and the second conveying component 2. The two first adjusting components 3 are connected by a driving frame 5. A second adjusting component 4 is provided at the lower end of the driving frame 5. The second adjusting component 4 is used to adjust the inclination angle of the first conveying component 1 and the second conveying component 2. Both the first conveying component 1 and the second conveying component 2 include an outer side plate 11 and an inner side plate 12. Multiple driving rollers 13 are arranged between the outer side plate 11 and the inner side plate 12. A conveyor belt 14 is arranged outside the driving rollers 13. The inner side plate 12 and the conveyor belt 14 are at the same horizontal height. When placing the seat, the bottom of the seat can contact the surface of the conveyor belt 14. Multiple through holes 141 are provided on the conveyor belt 14. The outer side plate 11 and the inner side plate 12 are fixedly connected by a connecting plate 110. A negative pressure pump assembly 16 is provided at the lower end of the connecting plate 110. A negative pressure adsorption chamber 18 is formed between the outer side plate 11, the inner side plate 12 and the conveyor belt 14. The negative pressure pump assembly 16 is connected to the negative pressure adsorption chamber 18 through an air pipe 17 to connect the air path through the air pipe 17.

[0038] The first conveying assembly 1 and the second conveying assembly 2 together constitute a conveying platform. When conveying the high-speed rail seat cushion, the seat cushion is placed between the first conveying assembly 1 and the second conveying assembly 2. One side of the lower part of the seat cushion contacts the conveyor belt 14 of the first conveying assembly 1, and the other side of the lower part of the seat cushion contacts the conveyor belt 14 of the second conveying assembly 2. The first conveying assembly 1 and the second conveying assembly 2 work synchronously to drive the conveyor belt 14 to move synchronously, and the seat cushion moves synchronously with the conveyor belt 14 to achieve the conveying of the seat cushion.

[0039] Adjust the distance between the first conveying assembly 1 and the second conveying assembly 2 according to the size and structure of the high-speed rail seat cushion. When placing the seat cushion, make one side of the lower part of the seat cushion just contact the conveyor belt 14 of the first conveying assembly 1, and make the other side of the lower part of the seat cushion just contact the conveyor belt 14 of the second conveying assembly 2. By adjusting the distance between the first conveying assembly 1 and the second conveying assembly 2, the flexibility and versatility of the conveying platform are improved. The conveying platform is applicable to seat cushions of different specifications and sizes, and can realize the conveying of various seat cushion structures.

[0040] In some examples, one end of a set of driving rollers 13 is connected to the output shaft of the first motor 15, and the first motor 15 is installed on the outer side plate 11. The driving rollers 13 are connected to both the outer side plate 11 and the inner side plate 12 through bearings, and the driving rollers 13 can rotate relative to the outer side plate 11 and the inner side plate 12.

[0041] When the first motor 15 works, it drives the driving roller 13 at one end to rotate. Through the transmission of the conveyor belt 14, it drives multiple sets of driving rollers 13 to rotate synchronously, thereby driving the conveyor belt 14 to move. The seat cushion structure is conveyed by the conveyor belt 14 during the movement process, and the first motor 15 is used as the power source of the conveying platform.

[0042] In some examples, one side edge of the conveyor belt 14 is in close contact with the inner side surface of the outer side plate 11 and is sealed with the outer side plate 11. The other side edge of the conveyor belt 14 is in close contact with the inner side surface of the inner side plate 12 and is sealed with the inner side plate 12.

[0043] When the first motor 15 works to drive the conveyor belt 14 to move relative to the outer side plate 11 and the inner side plate 12, one side edge of the conveyor belt 14 always maintains a sealed connection with the outer side plate 11, and the other side edge of the conveyor belt 14 always maintains a sealed connection with the inner side plate 12, thereby ensuring the sealing performance of the negative pressure adsorption chamber 18.

[0044] The negative pressure pump assembly 16 is internally provided with a negative pressure pump structure. When conveying the cushion, the negative pressure pump structure operates to extract the air inside the negative pressure adsorption chamber 18 through the air pipe 17, so that the negative pressure adsorption chamber 18 is always in a negative pressure state, that is, the multiple through holes 141 on the conveyor belt 14 are always in a negative pressure state. When the cushion is placed on the conveying platform and contacts the bottom of the conveyor belt 14, the cushion structure is adsorbed and fixed by the negative pressure adsorption force of the multiple through holes 141, and the cushion structure is adsorbed and fixed on the conveyor belt 14. The cushion structure moves smoothly along with the conveyor belt 14, effectively preventing the cushion from deviating from the specified movement trajectory or falling, and improving the stability during the cushion conveying process.

[0045] As Figure 7 shown, for the drive roller 13 at the rearmost end and the part of the conveyor belt 14 body in close contact with it, the multiple through holes 141 on this part of the belt body are not communicated with the negative pressure adsorption chamber 18. Therefore, the multiple through holes 141 on this part of the belt body do not generate negative pressure adsorption force. When the cushion is conveyed to the end by the conveying platform, the cushion structure automatically disengages from the conveyor belt 14 and enters the next production area, without the need to frequently switch the working state of the negative pressure pump assembly 16.

[0046] In some examples, the first adjustment assembly 3 includes a U-shaped seat 31. A second motor 32 is installed on one side surface of the U-shaped seat 31. The output shaft of the second motor 32 is fixedly connected to a bidirectional lead screw 33. The output shaft of the second motor 32 and the bidirectional lead screw 33 are fixedly connected through a coupling. A slide bar 34 is fixedly arranged on the U-shaped seat 31, and the slide bar 34 is located below the bidirectional lead screw 33. A first slide seat 35 and a second slide seat 36 are sleeved on the bidirectional lead screw 33, and the slide bar 34 passes through the first slide seat 35 and the second slide seat 36. The first slide seat 35 and the second slide seat 36 are both slidably connected to the slide bar 34.

[0047] Two sets of thread groove structures are arranged on the bidirectional lead screw 33, and the rotation directions of the two sets of threads are opposite. When the second motor 32 operates, it drives the bidirectional lead screw 33 at one end to rotate, thereby driving the first slide seat 35 and the second slide seat 36 to slide along the slide bar 34, driving the first slide seat 35 and the second slide seat 36 to approach or move away from each other. The positions of the first slide seat 35 and the second slide seat 36 are controlled by the rotation direction and the number of rotation turns of the output shaft of the second motor 32.

[0048] In some examples, the first slide seat 35 and the second slide seat 36 are respectively located on both sides of the bidirectional lead screw 33. Both the first conveying assembly 1 and the second conveying assembly 2 include support legs 19, and the support legs 19 are fixed on the outer side plate 11, and the support legs 19 and the outer side plate 11 are fixedly connected by welding.

[0049] In some examples, the first sliding seat 35 of the first adjusting component 3 is fixedly connected to the leg 19 of the first conveying component 1, and the second sliding seat 36 of the first adjusting component 3 is fixedly connected to the leg 19 of the second conveying component 2.

[0050] When the first sliding seat 35 slides along the sliding rod 34, the leg 19 of the first conveying component 1 slides synchronously along the sliding rod 34 following the first sliding seat 35. When the second sliding seat 36 slides along the sliding rod 34, the leg 19 of the second conveying component 2 slides synchronously along the sliding rod 34 following the second sliding seat 36. In this way, the first conveying component 1 and the second conveying component 2 are driven to slide along the sliding rod 34, and the first conveying component 1 and the second conveying component 2 are driven to approach or move away from each other, and the distance between the first conveying component 1 and the second conveying component 2 can be flexibly adjusted by the first adjusting component 3.

[0051] By adopting the above technical solution:

[0052] A negative pressure adsorption chamber 18 is formed between the outer plate 11, the inner plate 12 and the conveyor belt 14. When conveying the cushion, the negative pressure pump assembly 16 extracts the air inside the negative pressure adsorption chamber 18 through the air pipe 17, so that the negative pressure adsorption chamber 18 is always in a negative pressure state, and then a negative pressure adsorption force is generated by the multiple through holes 141 on the conveyor belt 14. When the bottom of the cushion contacts the conveyor belt 14, the cushion structure is adsorbed and fixed by relying on the negative pressure adsorption force of the multiple through holes 141, which is convenient for fixing the cushion.

[0053] The first conveying component 1 and the second conveying component 2 together constitute a conveying platform, and the distance between the first conveying component 1 and the second conveying component 2 can be correspondingly adjusted by the first adjusting component 3 according to the size structure of the cushion, improving the flexibility and versatility of the conveying platform and enabling the conveying of various cushion structures.

[0054] Embodiment 2:

[0055] Based on Embodiment 1, this embodiment introduces the specific structure of the second adjusting component 4 in a conveying device for high-speed rail cushion production. A first connecting seat 51 and a second connecting seat 52 are welded and fixed to the lower end of the driving frame 5, and both the first connecting seat 51 and the second connecting seat 52 are support connection points.

[0056] In some examples, the second adjusting component 4 includes a first support 41, a second support 42 and a hydraulic cylinder 43. The first connecting seat 51 is rotatably connected to the first support 41 through a rotating shaft, and the first connecting seat 51 can rotate relative to the first support 41. The cylinder body of the hydraulic cylinder 43 is rotatably connected to the second support 42 through a rotating shaft, and the cylinder body of the hydraulic cylinder 43 can rotate relative to the second support 42. The first connecting seat 51 takes the rotating shaft on the first support 41 as a base point and can make a circular motion within a certain range along this base point.

[0057] In some examples, one end of the push rod of the hydraulic cylinder 43 is fixedly connected with a connector 44.

[0058] In some examples, the connector 44 and the second connecting seat 52 are rotatably connected through a rotating shaft, and the second connecting seat 52 can rotate relative to the connector 44.

[0059] The hydraulic cylinder 43 is used as the power source of the second adjusting component 4. When the hydraulic cylinder 43 works, it drives its push rod to extend and retract. The push rod of the hydraulic cylinder 43 drives the connector 44, drives the second connecting seat 52 through the connector 44, drives the driving frame 5 through the second connecting seat 52, and the driving frame 5 drives the conveying structure on its upper part to move synchronously. At the same time, the first connecting seat 51 takes the rotating shaft on the first support 41 as the base point and rotates correspondingly along this base point. The cylinder block of the hydraulic cylinder 43 takes the rotating shaft on the second support 42 as the base point and rotates correspondingly along this base point. The connector 44 takes the rotating shaft on the second connecting seat 52 as the base point and rotates correspondingly along this base point to adjust the inclination angles of the upper first conveying component 1 and the second conveying component 2. The inclination angles of the first conveying component 1 and the second conveying component 2 are controlled by the extension and retraction stroke of the push rod of the hydraulic cylinder 43.

[0060] By adopting the above technical solutions:

[0061] It is possible to adjust the inclination angles of the first conveying component 1 and the second conveying component 2 through the second adjusting component 4 according to the actual use requirements, and then adjust the conveying angle and the conveying height, and adjust the conveying posture of the conveying device according to the position of the subsequent platform, improving the flexibility and versatility of the conveying platform.

[0062] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
