Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to an aluminum profile conveying equipment. Background Technology

[0002] Chain conveyors are a common type of material handling machinery, widely used in industrial production, logistics, and other fields. They mainly consist of chains, sprockets, drive units, and conveying troughs, and continuously transport materials through the cyclical movement of the chain.

[0003] The main characteristics of chain conveyor equipment are high load-bearing capacity, long conveying distance, and stable and reliable operation. Based on different chain structures, it can be divided into plate chains, roller chains, and engineering plastic chains. Plate chains are suitable for conveying heavy materials, roller chains have low running resistance and are suitable for long-distance conveying, while engineering plastic chains have corrosion resistance. Maintenance requires regular checks of chain tension, lubrication, and wear. Compared to belt conveyors, chain conveyor equipment is more resistant to high temperatures and impacts.

[0004] The authorization announcement number CN111285015B discloses an adjustable chain storage conveyor belt. According to its instruction manual and drawings, the positioning mechanism and the chain conveyor belt (conveyor mechanism) are integrated into one unit, which is applicable to a wide variety of products and is easy to adjust. The use of handwheel, T-type screw and T-type nut allows for simultaneous control of two tracks and makes it easier to adjust the width of the two tracks.

[0005] However, the solution has certain limitations: 1. The tension adjustment of the chain is inconvenient, which affects the speed of subsequent equipment maintenance and reduces the repair speed; 2. When the equipment is conveying large aluminum profiles, the profiles are prone to falling during the conveying process, which poses a safety hazard during use. Summary of the Invention

[0006] This invention addresses the problems encountered during the maintenance and material conveying of chain conveyor equipment. It provides an aluminum profile conveying device where users can adjust the tension using a second tensioning gear based on chain wear or load changes to ensure the chain is always in optimal working condition. During the conveying of aluminum profiles, the gap between adjacent conveying limit plates prevents the conveyed material from slipping off the chain surface.

[0007] The objective of this invention is achieved through the following technical solution: an aluminum profile conveying device, comprising several conveying support frames arranged in parallel, a chain for conveying materials on the conveying support frame, a tensioning mechanism below the conveying support frame for tensioning the chain, the tensioning mechanism being able to adjust the tension of the chain, and a driving element for driving the tensioned chain to move inside the tensioning mechanism, and limiting mechanisms for preventing the conveyed materials from slipping off the chain on both sides of the conveying support frame.

[0008] Preferably, each of the conveying support frames is provided with a plurality of rotatable guide wheels inside, and a chain pad is placed on the surface of the conveying support frame. The chain is wound around the surface of the guide wheels and is slidably mounted on the surface of the chain pad.

[0009] Preferably, each tensioning mechanism includes a gear support plate, a first tensioning gear, a second tensioning gear, and a third tensioning gear. Gear support plates are provided on both sides of each conveying support frame. The first tensioning gear and the second tensioning gear are provided inside the conveying support frame. A third tensioning gear is rotatably provided on an adjacent gear support plate. The first tensioning gear and the second tensioning gear are located above the third tensioning gear. A waist-shaped through hole is provided on both sides of the conveying support frame. When the second tensioning gear slides inside the waist-shaped through hole, it adjusts the tension of the chain.

[0010] Preferably, each conveying support frame has several screw support plates on its inner and outer walls, and a support screw is provided between adjacent screw support plates. The support screw is provided with several locking nuts, and each second tension gear has a tension support shaft inside. The through holes at both ends of the tension support shaft are installed between the locking nuts on the surface of the support screw.

[0011] Preferably, a drive support plate is provided between adjacent gear support plates, and the drive element is a drive motor. The end of the drive motor shaft is provided with a drive long shaft connected to the inside of the third tension gear. This arrangement is to enable the drive of the second tension gear.

[0012] Preferably, the limiting mechanism includes a first limiting base, a first support column, a second support column, and a conveying limiting plate. Each outer wall of the conveying support frame is provided with a plurality of first limiting bases. The surface of each first limiting base is provided with a first support column and a second support column perpendicular to the first support column. The end of each second support column is connected to a conveying limiting plate. The gap between adjacent conveying limiting plates can restrict the conveyed material from slipping off the surface of the chain.

[0013] Preferably, each of the conveying support frames is further provided with a number of second limiting bases on its outer side wall, and a third support column is installed on the side of each second limiting base. After the top of each third support column is obliquely cut off, an oblique guide plate is provided. The distance between the oblique guide plates on different conveying support frames is greater than the distance between adjacent conveying support frames. This setting is to enable the aluminum profile to be conveyed according to the set trajectory during the conveying process.

[0014] Preferably, the bottom of the conveying support frame is equipped with an equipment support frame composed of several metal profiles, and the side of the adjacent third support column is provided with a reinforcing plate to enhance the stability of the inclined guide plate. This arrangement is to achieve higher support strength and less bending of the inclined guide plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Users can adjust the tension using the second tension gear according to the wear of the chain or changes in load to ensure that the chain is always in the best working condition and to prevent material blockage, chain skipping or falling off. It should be noted that the adjustment should be made when the equipment is stopped to effectively avoid the safety hazards of adjusting during operation.

[0017] 2. During the conveying of aluminum profiles, the gap between adjacent conveying limit plates can prevent the conveyed material from slipping off the surface of the chain, so that the aluminum profiles move along the set trajectory, thereby improving the safety level during the conveying process.

[0018] 3. During the movement, the chain can slide on the surface of the chain pad. Several protrusions on the surface of the chain pad can hold the chain in place and prevent it from shifting to the sides, thus making the chain more accurate during the conveying process.

[0028] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, an aluminum profile conveying device includes several conveying support frames 1 arranged side by side. Each conveying support frame 1 is equipped with a chain 2 for conveying materials. A device support frame 10 composed of several metal profiles is installed at the bottom of each conveying support frame 1. Each conveying support frame 1 has several rotatable guide wheels 11 inside. Chain pads 12 are placed on the surface of each conveying support frame 1. The chain 2 is wound around the surface of the guide wheels 11 and is slidably mounted on the surface of the chain pads 12.

[0030] During movement, chain 2 can slide on the surface of chain pad 12. Several protrusions on the surface of chain pad 12 can hold chain 2 in place, preventing it from shifting to either side. Guide wheel 11 plays a supporting and guiding role during the movement of chain 2. After placing a large aluminum profile on the surface of chain 2, the aluminum profile can be simultaneously transported to the designated position as chain 2 moves.

[0031] Please continue to refer to this. Figure 3 and Figure 5 Below the conveying support frame 1 is a tensioning mechanism 3 for tensioning the chain 2. The tensioning mechanism 3 can adjust the tension of the chain 2. The tensioning mechanism 3 is also provided with a drive element 4 for driving the tensioned chain 2 to move.

[0032] In this embodiment, each tensioning mechanism 3 includes a gear support plate 31, a first tensioning gear 32, a second tensioning gear 33, and a third tensioning gear 34. Each conveying support frame 1 has a gear support plate 31 on its inner and outer sides. The first tensioning gear 32 and the second tensioning gear 33 are provided inside the conveying support frame 1. The third tensioning gear 34 is rotatably provided on the adjacent gear support plate 31. The first tensioning gear 32 and the second tensioning gear 33 are located above the third tensioning gear 34. The conveying support frame 1 has waist-shaped through holes 6 on both sides.

[0033] like Figure 5 As shown, with this setup, chain 2 first wraps around the upper part and left side of the first tension gear 32, then pulls chain 2 down to wrap around the lower side and left side of the third tension gear 34, then pulls chain 2 up to wrap around the right side and upper part of the second tension gear 33, and then the leftmost and rightmost ends of chain 2 wrap around the surface of the guide wheel 11 respectively.

[0034] The third tensioning gear 34, driven by the driving element 4, primarily drives the movement of the entire chain 2. The first tensioning gear 32 mainly guides and supports the chain 2 before tensioning. The second tensioning gear 33 adjusts the tension of the chain 2 by sliding inside the oblong through hole 6.

[0035] Users can adjust the tension in real time according to the wear of chain 2 or changes in load to ensure that chain 2 is always in the best working condition and to prevent material blockage, chain skipping or falling off. It should be noted that the adjustment should be made when the equipment is stopped to effectively avoid the safety hazards of adjusting during operation.

[0036] To enable adjustment of the second tensioning gear 33, each conveying support frame 1 has a screw support plate 13 on its inner and outer surfaces, and a support screw 14 is provided between adjacent screw support plates 13. The support screw 14 is provided with several locking nuts 15, and each second tensioning gear 33 has a tensioning support shaft 35 inside. The through holes at both ends of the tensioning support shaft 35 are installed between several locking nuts 15 on the surface of the support screw 14.

[0037] When the position of the second tensioning gear 33 needs to be adjusted, adjust the adjacent locking nut 15 to increase the gap, then push the tensioning support shaft 35 to change its position on the surface of the support screw 14. At this time, the second tensioning gear 33 moves with the movement of the support screw 14. After adjusting to the specified position, tighten the locking nut 15 again to clamp the end of the support screw 14.

[0038] Please refer to Figure 6As shown, a drive support plate 36 is provided between adjacent gear support plates 31. The drive element 4 is a drive motor, and the end of the drive motor's shaft is provided with a drive long shaft 41 connected inside the third tension gear 34. When the drive motor's shaft rotates, it drives the drive long shaft 41 to rotate, and the drive long shaft 41 simultaneously drives the third tension gear 34 to rotate, thereby providing a driving force source for the entire chain 2.

[0039] Please continue to refer to this. Figure 3 and Figure 5 The conveying support frame 1 is further provided with limiting mechanisms 5 on both sides to prevent the conveyed material from slipping off the chain 2. The limiting mechanism 5 includes a first limiting base 51, a first support column 52, a second support column 53, and a conveying limiting plate 54. Each outer wall of the conveying support frame 1 is provided with a plurality of first limiting bases 51. The surface of each first limiting base 51 is provided with a first support column 52 and a second support column 53 perpendicular to the first support column 52. The end of each second support column 53 is connected to the conveying limiting plate 54.

[0040] With this setup, the aluminum profile to be transported is placed on the surface of the chain 2 by hoisting. During the transport of the aluminum profile, the gap between adjacent transport limit plates 54 can restrict the transported material from slipping off the surface of the chain 2, so that the aluminum profile moves along the set trajectory, improving the safety level during the transport process.

[0041] Each of the conveying support frames 1 is also provided with a number of second limiting bases 55 on its outer side wall. Each of the second limiting bases 55 is provided with a third support column 56 on its side. Each of the third support columns 56 is provided with an inclined guide plate 57 after its top is cut off at an angle. The distance between the inclined guide plates 57 on different conveying support frames 1 is greater than the distance between adjacent conveying support frames 1. The sides of adjacent third support columns 56 are provided with reinforcing plates 58 for enhancing the stability of the inclined guide plates 57.

[0042] Because there is a slight sway when the aluminum profile is placed onto the surface of the chain 2 during hoisting, the inclined guide plate 57 can limit the deviation of the sway during the downward movement of the aluminum profile and guide the aluminum profile during the descent, so that the aluminum profile can be gradually placed into the gap between the adjacent conveyor limit plates 54, effectively improving the accuracy of material placement.

[0043] Working principle and usage of this utility model:

[0044] First, several conveying devices of this embodiment are placed end to end. Then, the aluminum profiles to be conveyed are lifted by a hoisting device and moved to the gap between adjacent conveying limit plates 54 and continuously lowered. During the descent, the tilting guide plate 57 can limit the swaying deviation and guide the aluminum profiles during descent, so that the aluminum profiles can be gradually placed into the gap between adjacent conveying limit plates 54.

[0045] Then, when the drive motor shaft rotates, it drives the drive shaft 41 to rotate, which in turn drives the third tension gear 34 to rotate. The third tension gear 34 drives the movement of the entire chain 2. During the movement, the chain 2 can slide on the surface of the chain pad 12. Several protrusions on the surface of the chain pad 12 can hold the chain 2 in place, preventing it from shifting to either side. The guide wheel 11 plays a supporting and guiding role during the movement of the chain 2. After a large aluminum profile is placed on the surface of the chain 2, the aluminum profile can be simultaneously transported to the designated position during the movement of the chain 2.

[0046] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
