Description

Technical Field

[0001] The utility model generally relates to the technical field of lithium batteries. More specifically, the utility model relates to a long-distance conveying device. Background Art

[0002] A preheating tunnel furnace is an industrial heating device mainly used for continuously heating materials, which is commonly found in multiple industries such as electronic product manufacturing, food processing, printing, and coating curing. Its working principle is to use heat sources such as electric heating, gas, or infrared rays to uniformly heat the products on the conveyor belt through a tunnel-shaped furnace cavity to meet the predetermined temperature requirements. The preheating process can improve production efficiency and ensure the stability of product quality.

[0003] The lithium battery preheating tunnel furnace is used for preheating the bare battery cells after winding before hot pressing and shaping, so that hot pressing can quickly achieve the shaping effect and improve the single-line production capacity. The preheating tunnel furnace mainly consists of an automatic feeding module, an air circulation baking module, a conveying fixture module, a dust removal module, a control module, etc. Its working principle is as follows: the battery cells move step by step on the conveyor line in the constant-temperature baking furnace. The air circulation fan drives the air, which is heated by the heating tube and passes through the high-efficiency filter, and then is conveyed to the surface of the battery cells to heat the battery cells to achieve the purpose of preheating the battery cells. Among them, the battery cell conveyor line often adopts a sprocket and chain structure. Due to the long conveying distance of the conveyor line of the tunnel furnace, the problem of chain detachment occurs frequently.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Now, embodiments will be described with reference to the drawings. It should be understood that, for simplicity and clarity of illustration, where considered appropriate, reference numerals may be repeated in the drawings to indicate corresponding or similar elements. Additionally, the present utility model sets forth numerous specific details in order to provide a thorough understanding of the embodiments described herein. However, those of ordinary skill in the art will understand that the embodiments described herein may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the embodiments described herein. Moreover, this description should not be regarded as limiting the scope of the embodiments described herein.

[0025] According to an embodiment of the present utility model, a long-distance conveying device is provided, including: two fixed support frames arranged in the left-right direction, any one of the fixed support frames having an upper support portion 11 and a lower support portion 12, the end of one upper support portion 11 being fixedly connected to the end of the lower support portion 12 located below it, a fixed seat being provided at the end, a sprocket 13 and a driving device 14 for rotating the sprocket 13 being assembled on the fixed seat, further including an ear chain 15 and a tray 16, the ear chain 15 meshing with the sprocket 13 and being laid along the upper surfaces of the upper support portion 11 and the lower support portion 12 respectively, first limiting portions and second limiting portions for restricting the left-right displacement of the ear chain 15 being provided at the upper surfaces of the upper support portion 11 and the lower support portion 12 respectively, and the left and right ends of the tray 16 being fixedly connected to the two ear chains 15 located above the two fixed support frames respectively.

[0026] Here, a connecting member can be used to fixedly connect the end of one upper support portion 11 to the end of the lower support portion 12 located below it. The connecting member can be arranged on one side in the conveying direction or the laying direction of the ear chain 15, such as the left side or the right side, so as to avoid interference with the ear chain 15 or the tray 16.

[0027] In one embodiment, the upper support portions 11 of the two fixed support frames are sequentially connected by multiple sections of hollow square tubes. For example, along the conveying direction, multiple sections of hollow square tubes are sequentially bolted together.

[0028] In one embodiment, in the conveying direction, the upper support portion 11 has a notch 31 that penetrates up and down at every preset length. The notch 31 is used to accommodate a guiding gear 32. The guiding gear 32 is located between the upper support portion 11 and the lower support portion 12. Each guiding gear 32 meshes with the ear chain 15 on the upper surface of the upper support portion 11. There is a gap between each guiding gear 32 and the ear chain 15 on the upper surface of the lower support portion 12. A guiding gear mounting seat is provided at the notch 31, and the guiding gear mounting seat is adjustably arranged relative to the notch 31.

[0029] The position of the notch 31 here can be set anywhere on the upper support portion 11. If the upper support portion 11 is connected by multiple sections of hollow square tubes, it is preferably to avoid the connection part of two adjacent hollow square tubes.

[0030] In the above embodiment, the preset length is 1 - 2 meters. That is, a notch 31 can be set every about 1 - 2 meters, so that the interval between adjacent guiding gears 32 is the same as the interval between adjacent notches 31.

[0031] In the above embodiments, the first limiting portion is a first chute 51 provided on the upper surface of the upper support portion 11. The lug chain 15 located on the upper surface of the upper support portion 11 is located within the first chute 51. The first chute 51 has an opening corresponding to the position of the notch 31 of the upper support portion 11 and having the same size.

[0032] The material of the first chute 51 can be nylon. In terms of structure, it can be a U-shaped groove in a U shape. Since the lug chain 15 is laid within the first chute 51, and the first chute 51 is placed on the upper surface of the upper support portion 11, when the guiding gear 32 passes through the notch 31 to engage with the lug chain 15, the first chute 51 also needs to have an opening corresponding to the position of the notch 31 and having the same size. The opening should at least not be smaller than the notch 31.

[0033] In addition to limiting the lug chain 15 located on the upper support portion 11 through the first limiting portion, a second limiting portion is also provided to limit the lug chain 15 on the lower support portion 12. In one embodiment, the second limiting portion includes a second chute 71 provided on the outer side of the upper surface of the lower support portion 12, and a plurality of stoppers 72 spaced apart and provided on the inner side of the upper surface of the lower support portion 12. The lug chain 15 located on the upper surface of the lower support portion 12 is located within the second chute 71 and has a preset gap with any one of the stoppers 72. The lowest point of each stopper 72 is higher than the highest point of the lug chain 15 located within the second chute 71.

[0034] In the above embodiments, the second chute 71 is an L-shaped groove. The bottom of the L-shaped groove is used for laying the lug chain 15. The side portion of the L-shaped groove and the stopper 72 jointly limit the displacement of the lug chain 15 in the left and right directions.

[0035] The stopper 72 can be fixed by using an inverted U-shaped bracket 91. One side of the U-shaped bracket 91 is fixedly connected to the lower support portion 12. The inner side of the bottom of the U-shaped bracket 91 is located directly above the lower support portion 12, and the inner side of the bottom is higher than the lug chain 15 provided on the upper surface of the lower support portion 12. The stopper 72 is fixedly provided inside the U-shaped bracket 91. Thus, the left and right sides and the bottom of the lug chain 15 are respectively surrounded by the inverted U-shaped bracket 91 and the L-shaped groove, effectively preventing the occurrence of the problem of falling off.

[0036] In some embodiments, it further includes an adjusting gear for adjusting the tension of the lug chain 15. The adjusting gear is provided on an adjusting gear mounting seat. The adjusting gear mounting seat is adjustably provided relative to the upper support portion 11 or the lower support portion 12 to adjust the tension of the lug chain 15 as needed.
