Specifically, the fixed pulleys are provided with a plurality of fixed pulleys, the use functions of the fixed pulleys at different positions can be different, and with reference to fig. 2 and 3, the fixed pulleys comprise a first fixed pulley 432 corresponding to the upper part of the output pulley 431, the conveyor belt 41 passes around the inner side of the first fixed pulley 432, and the conveyor belt 41 is guided to extend in a direction away from the output pulley 431 by the first fixed pulley 432; a second fixed belt wheel 433 is arranged on one side of the tensioning wheel 434, which is close to the output belt wheel 431, so that the conveyor belt 41 can bypass the tensioning wheel 434, and the length of the conveyor belt 41 can be adjusted by the transversely sliding tensioning wheel 434, so that the aim of adapting to the lifting of the ejection mechanism 20 is fulfilled; a third fixed pulley 435 is provided at both ends near the top side of the track plate 10, respectively, and the conveyor belt 41 is tensioned by the two third fixed pulleys 435 so that the conveyor belt 41 can be disposed parallel to the upper edge of the track plate 10.

In existing conveyor track structures, the track plate body is typically a steel base plate that is perforated with holes and slots to meet the installation requirements of the jacking mechanism, belt conveyor mechanism, and other components. Although the steel substrate has the advantages of high hardness, high strength and good durability, the steel substrate also has the defects of heavy weight, difficult processing and the like, and further the problems of high processing cost, low efficiency and the like of the existing track plate main body are caused.

In order to overcome the above technical problems, as shown in fig. 7-12, the present embodiment provides a track plate 10, which is particularly applicable to the aforementioned conveying track, and the track plate 10 can be used as a support for other necessary devices or apparatuses on the conveying track, so that each device or apparatus can cooperate to realize the functions of conveying and positioning the workpieces 50 of the aforementioned conveying track.

In the track slab 10 of the present embodiment, the base profile of the main body structure (i.e. the main body 11) of the track slab 10 is made of a soft metal material, and the hardness of the base profile itself is low, so that the processing difficulty of forming holes, grooves and other structures on the profile is obviously lower, and the lower processing difficulty is obviously beneficial to reducing the processing cost and improving the processing efficiency. Therefore, the structure of the track plate 10 of the present embodiment can solve the problems of high processing cost, low efficiency, and the like of the conventional track plate body.

However, due to the defects of the main plate 11, such as soft texture and low strength, the workpiece 50 moving relative to the track plate 10 is easy to collide and rub, so that the main plate 11 is easy to wear and deform in practical use, which is why the track plate 10 is generally manufactured only from steel with high strength and hardness, rather than aluminum alloy with easier processing and lighter weight.

In order to overcome the negative problems of the main plate 11 itself, referring to fig. 4 and 7-9, the track plate 10 structure of the present embodiment further includes a guide block 12, and the main plate 11 has a first end 1111 and a second end 1112 opposite to each other; the first end 1111 and/or the second end 1112 are respectively mounted with a guide block 12, and the guide block 12 guides the entered workpiece 50 so that the main plate body 11 is not impacted by the entered workpiece 50.

Specifically, the inventors have found that during actual use, when the workpiece 50 is transferred from the previous station to the transfer rail, impact abrasion is likely to occur between the workpiece 50 and the end of the rail plate 10 during the process of entering and exiting the transfer rail due to the change of the transfer rail, and when the workpiece 50 completely enters the transfer rail, friction between the workpiece 50 and the transfer rail is not obvious due to the matching of the plate entering distance of the transfer rail and the width dimension of the workpiece 50.

In this embodiment, the independent guide blocks 12 are mounted at the first end 1111 and/or the second end 1112 of the main board 11, and specifically, in practical application, when the first end 1111 is fixedly set as the input end of the conveying track and the second end 1112 is set as the output end of the conveying track, the guide blocks 12 may be disposed only at the first end 1111; when the first end 1111 is fixedly set as an output end of the transfer rail and the second end 1112 is set as an input end of the transfer rail, the guide block 12 may be provided only at the second end 1112; when the input and output ends of the transfer track can be exchanged between the first end 1111 and the second end 1112, guide blocks 12 can be provided on the first end 1111 and the second end 1112, respectively.

Based on the structure of the track plate 10 with the guide blocks 12 in the embodiment, when the workpiece 50 enters between the two track plates 10, the guide blocks 12 are contacted first, and smoothly enter between the two conveying tracks under the guiding action of the guide blocks 12; compared with the whole main board body 11, the guide block 12 has small volume and less material consumption, so the manufacturing cost is lower, and even if the guide block 12 is impacted to deform or wear in the use process, the guide block 12 can be independently replaced with a new guide block, thereby greatly reducing the maintenance cost and the maintenance difficulty of later use. In addition, the guide block 12 with higher hardness can be adopted to improve the impact resistance and the wear resistance of the guide block, so that the guide block 12 has longer service life.

In an embodiment, a guiding inclined plane is disposed on one side of the guiding block 12 located on the first installation side, and the workpiece 50 can smoothly enter between the guiding blocks 12 on two sides by using the guiding inclined plane, and meanwhile, the direction of the workpiece 50 is adjusted, so that two side edges of the workpiece can be kept parallel to one side of the main board 11 located on the first installation side, and friction between the workpiece 50 and the surface of the main board 11 is avoided.

In summary, according to the track board 10 structure of the present embodiment, the guide blocks 12 are respectively disposed at two ends of the main board 11, so as to avoid impact abrasion of the main board 11 by the entered workpiece 50, and achieve the effect of reducing the later maintenance cost, for example, the guide blocks 12 with higher hardness can be adopted to improve the impact resistance and abrasion resistance, or when the guide blocks 12 are worn and deformed seriously, the guide blocks 12 can be replaced independently. Based on the setting of avoiding the mainboard body 11 by the work piece 50 impact wearing and tearing of entering based on the guide block 12, can adopt the softer metallic material of texture to make the mainboard body 11, obviously, for traditional high strength, high rigidity's steel base plate, the processing degree of difficulty of the weaker mainboard body 11 of texture is with low, so can improve the machining efficiency of track board 10 and reduce processing cost.

In one embodiment, referring to fig. 9, the first end 1111 and/or the second end 1112 are provided with a slot 113 corresponding to the guide block 12, and the guide block 12 is inserted into the slot 113.

Specifically, only be provided with draw-in groove 113 at the tip of installing guide block 12, provide draw-in groove 113 installation guide block 12, can realize the quick counterpoint installation of guide block 12, reduce the installation degree of difficulty of guide block 12. Furthermore, the side wall of the guide block 12 can be limited by the clamping groove 113, so that the mounting stability of the guide block 12 is improved.

In this embodiment, the guiding block 12 mainly serves to provide guiding for the workpiece 50 entering between the conveying tracks, and at the same time avoid the workpiece 50 striking the main plate 11, so the height of the guiding block 12 is required to ensure a plate thickness capable of covering the workpiece 50 entering into the conveying tracks. Therefore, it is preferable that the card slot 113 is opened at the top side of the main board body 11, and when the card slot 113 on the main board body 11 is opened, it is necessary to ensure that the bottom surface of the card slot 113 is not higher than the top surface of the conveyor belt 41 installed later.

In an embodiment, referring to fig. 9, a threaded hole 1131 is formed in the bottom side of the main board 11 located at the clamping groove 113, a positioning hole 121 is correspondingly formed in the guide block 12, and a screw 122 penetrates the positioning hole 121 and is in threaded connection with the threaded hole 1131 so as to fix the guide block 12 in the clamping groove 113.

The guide block 12 is locked on the main board body 11 by the screw 122, and the fixing mode has the advantages of simplicity in disassembly and assembly and good fixing reliability.

In one embodiment, referring to fig. 2, 3, 6 and 7, the top of the main board 11 is provided with a wear-resistant strip 13, the wear-resistant strip 13 is disposed parallel to the conveying direction of the workpiece 50, and the wear-resistant strip 13 is used for contacting the workpiece 50 to avoid the main board 11 from being rubbed by the workpiece 50.

Specifically, although the friction between the edge of the workpiece 50 and the inner side of the track plate 10 is slight after the workpiece 50 enters the inner side of the track plate 10, if the workpiece 50 directly contacts the friction main plate 11, obvious grinding marks are easily generated on the inner side of the track plate 10 after long-term use due to the soft texture of the main plate 11. In order to avoid the problem, the scheme sets the wear-resistant strip 13 on the top side of the main board body 11, and the wear-resistant strip 13 is used for contacting the edge of the workpiece 50, so that the workpiece 50 in the conveying process is prevented from directly contacting the friction main board body 11, and the problem of friction damage of the main board body 11 can be avoided.

Preferably, the wear strip 13 is a steel strip that is fastened to the main plate body 11 by screws.

In one embodiment, the main board 11 is made of aluminum alloy by extrusion molding. The aluminum alloy material has the advantages of soft texture and extrusion processing, and the extrusion processing has the advantages of rapid molding and low molding cost, and accords with the concept of reducing the cost of the embodiment. In addition, the aluminum alloy material has the advantages of light weight, low cost and the like.

In one embodiment, the hardness of the guide block 12 is not less than 60HRB.

Through multiple experiments by the inventor, the hardness of the guide block 12 is controlled to be above 60HRB, so that the requirement of resisting the impact of the workpiece 50 can be basically met, namely, after the workpiece 50 is impacted for multiple times, the guide block 12 is not easy to deform and cannot generate obvious abrasion. Preferably, the guide block 12 is made of stainless steel, such as 304 stainless steel, 312 stainless steel, etc., and the stainless steel has the advantages of high hardness, low cost, etc.

In one embodiment, referring to fig. 6-11, a through slot 114 is provided in the main board 11, which extends in the same direction as the length direction of the main board 11.

Specifically, the through groove 114 is formed in the main board body 11, so that the processing consumable of the main board body 11 can be effectively reduced, and the effects of reducing the material cost, reducing the weight and the like are achieved. Importantly, the through groove 114 of the scheme can be directly formed by one-step extrusion in the extrusion process, namely, the extruded profile is provided with the through groove 114, and the through groove 114 does not need to be grooved in a later period, so that the method has the advantage of rapid forming.

In one embodiment, referring to fig. 11, the sidewall thickness d of the through slot 114 is not less than 3mm.

That is, the material thickness of each position of the main plate body 11 is controlled to 3mm or more, which ensures that the main plate body 11 has sufficient strength, and ensures durability and stability of the entire track plate 10.

In one embodiment, referring to fig. 11, the main plate body 11 includes a base portion 116 and a main support plate portion 115, the main support plate portion 115 is located at a top side of the base portion 116, and the main support plate portion 115 has a height of not less than 80mm and a thickness of not more than 25mm; the thickness c of the base portion 116 is greater than the thickness of the main support plate portion 115.

The base portion 116 having a larger thickness is provided, so that the strength of the main plate body 11 can be effectively enhanced.

Importantly, if the base portion 116 protrudes at the second mounting side relative to the main support plate portion 115, in practice the total width of the two co-operating track plates 10, i.e. the distance between the surfaces of the two base portions 116 at the second mounting side; in order to reduce the occupied space of the whole conveying equipment as much as possible and improve the utilization rate of the factory building space, the base part 116 of the scheme is only protruded relative to the main supporting plate part 115 at the first installation side, and the base part 116 and the main supporting plate part 115 are flush at the second installation side, so that the outer surface distance of the two track plates 10 which are operated together can be minimized, namely the occupied space of the whole conveying equipment is reduced to the greatest extent in practical application. Particularly when multiple transports are first placed side by side, the main support plate portions 115 of two adjacent track plates 10 in two lines can be brought into close proximity, and the compactness of the installation between the transfer tracks as a whole is more pronounced.

The thickness of the main supporting plate portion 115 is controlled to be within 25mm, so that the occupied space of the conveying apparatus can be minimized in practical use. In order to avoid the problem, the height of the main supporting plate portion 115 is controlled to be more than 80mm, so that the workpiece 50 can be supported to be high enough, a sufficient distance can be kept between the workpiece 50 and the base portion 116, and the conveying requirement of most of the workpieces 50 can be basically met.

In one embodiment, the through slot 114 includes a first through slot 1141 and a second through slot 1142 that are disposed in the main supporting plate portion 115 at an upper-lower interval, and a connecting rib 117 is formed between the first through slot 1141 and the second through slot 1142; a sliding groove 1121 for mounting the tension pulley 434 is provided on one side of the main plate body 11, and the sliding groove 1121 is provided on the connecting rib plate 117.
