Description

Technical Field

[0001] The utility model relates to the technical field of conveying, in particular to a lightweight V-shaped conveying chain. Background Art

[0002] V-shaped conveyor chain is a common conveyor carrier structure. Based on the characteristics of its V-shaped surface, it can stably convey cylindrical objects, such as paper rolls in paper mills and paper packaging factories. The V-shaped plate connected to the top of the chain is used to carry the paper roll. When working, the cylindrical surface of the paper roll lies on the symmetrical inclined surfaces on both sides of the V-shaped plate. Because the center of gravity of the paper roll theoretically coincides with the central symmetry plane of the V-shaped plate, it can always lie stably on the chain and be conveyed to the designated position when running or stationary.

[0003] The current V-type conveyor chain still has the problems of heavy weight, high consumables, difficult processing of some parts, high manufacturing cost and long production cycle. Specifically,

[0004] The V-shaped plate of the V-shaped conveyor chain is made of 8-12mm steel plate, which is heavy, consumes a lot of materials and has low rigidity. Due to the low rigidity, it deforms greatly when subjected to vertical heavy loads, resulting in insufficient contact between the outer rings of the bearings on both sides and the track, reducing the service life of the load-bearing bearings on both sides, thereby reducing the service life of the entire chain.

[0005] The sleeve of the V-type conveyor chain adopts a long sleeve (as shown in the Chinese utility model patent with announcement number CN206827479U), and rollers are arranged at both ends of the sleeve. This long sleeve and the structure with rollers at both ends have many consumables and large deformation of the sleeve during heat treatment. During processing, each sleeve needs to be tested for the cylindricity of the inner circle with a core rod. If the cylindricity is unqualified, it must be calibrated until it is qualified to ensure the smooth operation of the subsequent V-type conveyor chain, resulting in low production efficiency.

[0006] Therefore, it is of great significance to optimize the design of a new type of lightweight V-shaped conveyor chain to replace the V-shaped conveyor chain in the existing technology, thereby reducing costs, improving cost performance, reducing operating energy consumption, and adapting to market demand.

[0009] The sleeve is set in a short size, the sleeves at both ends of the V-shaped plate are independent of each other, and at least two inner chain plates are connected to the sleeve on one side of the V-shaped plate to support each side of the V-shaped plate through two supporting points.

[0010] Furthermore, the V-shaped plate includes a V-shaped portion, a horizontal portion and a bending portion, the bending portion is located at the two side edges of the V-shaped plate, the horizontal portion is located between the V-shaped portion and the bending portion, the inner link plate includes a first inner link plate and a second inner link plate, the first inner link plate is connected to the horizontal portion of the V-shaped plate, the second inner link plate is connected to the V-shaped portion of the V-shaped plate, and the outer link plate is connected to the horizontal portion.

[0026] Embodiment 1:

[0027] like Figure 1 As shown, embodiment 1 of the utility model provides a lightweight V-shaped conveyor chain, including a conveyor chain consisting of a V-shaped plate 1, an inner chain plate 2, an outer chain plate 3, a sleeve 4, a pin 5 and a bearing 6. Among them, the V-shaped plate 1, the inner chain plate 2, and the sleeve 4 are welded together in sequence to form an inner chain link, and the V-shaped plate 1 is welded with the outer chain plate 3 to form an outer chain link. The sleeve 4 of the inner chain link and the outer chain plate 3 of the outer chain link are both sleeved on the pin 5 so as to be able to rotate relative to the pin 5. The bearing 6 is arranged at the end of the pin 5, including a bearing inner ring and a bearing outer ring. The bearing inner ring and the pin 5 are fixed by interference fit or other means. The bearing outer ring can rotate relative to the bearing inner ring, and the bearing outer ring is in rolling contact with the support surface, so that the entire conveyor chain can move.

[0028] A plurality of the above-mentioned inner chain links and outer chain links are alternately assembled in the form of hinged connection to form an integral conveyor chain. In this embodiment, this conveyor chain is further improved as follows:

[0029] The sleeve 4 is of short size, and the sleeves 4 at both ends of the V-shaped plate 1 are independent of each other, rather than of integral long size. Correspondingly, at least two inner link plates 2 are connected to the sleeve 4 on one side, and preferably distributed at both ends of the sleeve 4, so as to support each V-shaped portion 101 of the V-shaped plate 1 through two supporting points, thereby improving the supporting strength and further preventing the deformation of the V-shaped plate 1. It can be understood that since the V-shaped portions 101 on both sides of the V-shaped plate 1 are inclined, the heights of the inner link plates 2 are set to be different.

[0030] In a specific implementation of this embodiment, the V-shaped plate 1 includes a V-shaped portion 101, a horizontal portion 102 and a bent portion 103. The bent portion 103 is located at the two end edges of the V-shaped plate 1, and the horizontal portion 102 is located between the V-shaped portion 101 and the bent portion 103. Correspondingly, the inner link plate 2 includes a first inner link plate 201 and a second inner link plate 202, the first inner link plate 201 is connected to the horizontal portion 102 of the V-shaped plate 1, and the second inner link plate 202 is connected to the V-shaped portion 101 of the V-shaped plate 1. The outer link plate 3 is also connected to the horizontal portion 102 to form a more stable support for the end of the V-shaped plate 1.

[0031] The scheme of using the short-size sleeve 4 can achieve the same or better effect as the long-size sleeve 4. The inner diameter and outer diameter of the short-size sleeve 4 are exactly the same as the long-size one. The length of the short-size sleeve 4 is about 15% of the long-size one, and the two short-size sleeves 4 are 30% of the length of the long-size one. Obviously, the short-size sleeve 4 saves 70% of the material and 70% of the heat treatment energy consumption compared with the long-size one, and the weight is reduced by 70%, and the processing difficulty and coaxiality inspection difficulty of the long-size sleeve 4 due to the large deformation during heat treatment are avoided.

[0032] At the same time, through the setting of the short-size sleeve 4, the thickness of the four inner chain plates 2 of each inner chain link can be 1 / 2 to 2 / 3 of the inner chain plates 2 of the existing V-type conveyor chain, and the number is twice the inner chain plates 2 of the existing V-type conveyor chain. When the outer circle of the sleeve 4 is engaged with the sprocket teeth, the bending resistance of the sleeve 4 is significantly improved compared with the long size, which fully meets the performance requirements of the V-type conveyor chain and saves costs.

[0033] Furthermore, by setting the short-size sleeve 4, the V-shaped plate 1 can also be improved in light weight. In this embodiment, the V-shaped plate 1 is made of a sheet metal process by forming a thin steel plate in one step, and is called a sheet metal V-shaped plate 1. Compared with the V-shaped plate 1 made of thick steel plates in the existing similar chains, it can save 40% to 50% of raw materials while ensuring strength, further reducing costs. Of course, it should be noted that the solution adopted in this embodiment is also applicable to the existing V-shaped plate 1 made of thick steel plates, such as Figure 2 As shown, it only has a V-shaped portion 101 and a horizontal portion 102 , and does not include a bent portion 103 .

[0034] The lightweight V-shaped conveyor chain provided in this embodiment can be used as Figure 3 shown.

[0035] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
