Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of logistics conveying equipment, especially to an easy-to-position split cantilever conveying chain. BACKGROUND

[0002] The conveying mode of small materials (strip, block, rod) is commonly belt conveying, synchronous belt conveying and conveying chain plate conveying, wherein the conveying chain plate is composed of chain links and chain plates, and the rollers of most conveying chain plates cannot actually roll. In simple straight conveying conditions with a short distance, the conveying is relatively stable, but in conveying with a long distance, especially in the process of conveying in a curve, the conveying of the conveying chain plate will be unstable, and the materials will climb due to the fast or slow conveying speed, wherein the main reason is that the frictional resistance between the chain plate of the conveying chain plate and the supporting track is too large. The structure of the conveying chain plate is usually that the chain plate is located directly above the chain link, and in the process of material conveying, since the width of the existing conveying chain plate is smaller than the material conveying width, especially when other conveying mechanisms need to be cooperated to complete the conveying, the prior art completes the transition through a Y-shaped part, the two sides of the Y-shaped part are located at the two sides of the chain plate, although the Y-shaped part can complete the handover or transfer of the materials, but for some special equipment that cannot be completely conveyed by the ordinary conveying chain plate, when the conveying chain plate cooperates with other conveying mechanisms to handover or transfer the materials, for example, when the conveying chain plate can only be conveyed by the side or the conveying chain plate can only be conveyed by the single cantilever, the handover or transfer of the materials cannot be completed perfectly and smoothly.

[0003] The prior art cantilever conveying chain plate is completed by three ordinary rollers (bearings) cooperating with three guide rail surfaces, as shown in the accompanying drawings Figure 1 of the specification, and this technology has a problem that the guide rail groove composed of the three guide rail surfaces is a dark groove, the machining difficulty is large, the cost is high, and in addition, when conveying in the case that the conveying distance is long or there is a curve, the conveying chain plate will be unstable or the materials will climb, and finally the materials cannot be smoothly handed over or transferred.

[0008] As a further description of the above technical scheme:

[0009] The clamping groove roller is in the form of a solid body or a bearing, and the cross-sectional shape is designed as a double-sided or single-sided shape, which is matched with the protrusion in the guide rail to realize quick positioning of the clamping groove roller.

[0010] As a further description of the above technical scheme:

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] As Figures 1-5As shown, the easy-to-position split cantilever conveying chain provided by the embodiment includes a guide rail 10 and a plurality of chain links connected end to end and rollingly assembled inside the guide rail 10, and a chain plate placed on the lower bottom surface of each chain link. Each chain link includes a link seat body 11, a vertical pin shaft 112 provided in a vertical shaft sleeve 111 at one end of the link seat, a horizontal pin shaft 114 provided on a horizontal fork 113 at the other end of the link seat, and the guide rail 10 is one of a straight guide rail or an arc-shaped guide rail. The horizontal pin shaft 114 is inserted into the vertical pin shaft 112 to achieve end-to-end splicing of two adjacent link seat bodies 11. The plurality of link seat bodies 11 spliced end to end can splice the plurality of chain links into a conveying chain structure, so that the conveying chain structure can slide in the straight guide rail or the arc-shaped guide rail.

[0030] In further detail, Figure 2 As shown, the link seat body 11 is provided with two roller bodies 12 in vertical height. The roller body 12 includes a roller shaft 121 mounted on the link seat body 11, a clamping groove roller 122 mounted on the roller shaft 121, and a locking screw 123 fixed to the clamping groove roller 122 through the end face thread connection. The roller shaft 121 serves as a fulcrum to facilitate the rotation of the clamping groove roller 122 around it, and the locking screw 123 limits the clamping groove roller 122 on the roller shaft 121.

[0031] In further detail, a bushing 115 and a bushing shaft 116 are installed in the middle groove of the link seat. The bushing 115 is installed in the middle groove of the link seat body 11, which provides a stable support surface to ensure that the roller body 12 can be firmly mounted on the side of the link seat body 11. At the same time, the bushing shaft 116 cooperates with the roller shaft 121 to further ensure the accurate positioning of the roller body 12 on the link seat body 11, preventing it from shifting or shaking during work. During the operation of the conveying chain, the roller body 12 will constantly contact and roll with the guide rail 10. Without the support of the bushing 115 and the bushing shaft 116, the direct friction between the roller shaft 121 and the link seat body 11 will cause serious wear and tear, affecting the service life of the conveying chain.

[0032] The use of the bushing 115 and the bushing shaft 116 can effectively reduce such friction and wear, prolonging the service life of the conveying chain. During the operation of the conveying chain, due to the change of the weight of the material and the conveying speed, a certain impact and vibration will be generated. The bushing 115 and the bushing shaft 116 have a certain elasticity, which can absorb and alleviate these impacts and vibrations, thereby protecting other components of the conveying chain from damage.

[0033] In addition, the design of the bushing 115 and the bushing shaft 116 makes them relatively easy to remove and replace from the link seat body 11. When they cannot continue to be used due to wear or damage, new bushings 115 and bushing shafts 116 can be conveniently replaced, thereby ensuring the normal operation of the conveying chain.

[0034] As Figures 6-10 shown, the card slot roller 122 is in the form of a solid or with rolling bearings, and its cross-sectional shape adopts a double-sided or single-sided design, which forms a concave-convex corresponding fit with the protrusion in the guide rail 10, realizing the quick positioning of the card slot roller 122; by setting two card slot rollers 122 on one side of the segment seat, when the roller card slot is matched with the supporting guide rail 10, the cantilever conveying chain is stably supported, so that the supporting guide rail 10 changes from the original dark groove which is difficult to process into the easy-to-process open groove. Not only makes the cantilever conveying chain easy to position, but also greatly reduces the machining difficulty of the guide rail 10 groove, and greatly saves the processing cost.

[0035] Among them, the cross-sectional shape of the card slot roller 122 is one of V-shaped cross-section 1224, circular arc cross-section 1225 or rectangular cross-section 1226. The design of V-shaped cross-section 1224 is mainly to provide stronger guidance and stability. In the conveying process, the V-shaped cross-section 1224 can form a closer fit with the guide rail surface, reduce lateral shaking, and ensure that the conveying chain can run smoothly in straight and curved conveying; improve the guidance and stability of the conveying chain, reduce the material climbing phenomenon, and is suitable for conveying scenes that need accurate control and positioning.

[0036] The design of the circular arc cross-section 1225 is mainly to reduce the friction and wear between the roller and the guide rail 10. The circular arc shape can provide a smoother rolling contact surface, reduce rolling resistance, and prolong the service life of the roller. Mainly reduce the friction and wear between the roller and the guide rail surface, improve the conveying efficiency. Suitable for long-distance, high-speed or heavy-load conveying scenes.

[0037] The design of the rectangular cross-section 1226 is mainly to provide stronger structural support and stability. The rectangular shape can withstand greater radial and axial loads, ensuring that the conveying chain can operate normally in harsh working conditions. Mainly improve the structural strength and carrying capacity of the conveying chain. Suitable for heavy-load, impact or large-vibration conveying scenes.

[0038] In addition, the design of two single-sided card slot rollers 122 is mainly to provide sufficient guidance and stability while reducing processing cost and complexity. Single-sided card slot roller 122 can more easily form a concave-convex corresponding fit with the guide rail 10, reducing the processing difficulty. Provide stable guidance and support, ensure smooth operation of the conveying chain. Reduce processing cost and complexity, improve conveying efficiency.

[0039] The design of one single-sided and one double-sided clamping groove roller 122 is mainly to provide more flexibility and adaptability while meeting the guiding and stability. The double-sided clamping groove roller 122 can provide stronger structural support and positioning capability, while the single-sided clamping groove roller 122 is more easily adapted to different guide rail 10 shapes and sizes. Combining the advantages of single-sided and double-sided clamping groove rollers 122, stronger stability and flexibility are provided. It is suitable for complex and variable conveying scenarios, and improves the adaptability and reliability of the conveying chain.

[0040] The above merely describes a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, within the technical range disclosed by the present application, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or changes, which should be covered within the protection scope of the present application.
