Description

Technical Field

[0001] The utility model belongs to the technical field of conveying devices, in particular to an active end supporting structure of a conveying line. Background Art

[0002] In automated production and manufacturing, conveyor lines are essential material transmission devices. Conveyor lines generally include brackets, drive mechanisms, and transmission mechanisms. Most drive mechanisms use motors, and there are many types of transmission mechanisms, such as synchronous pulleys with synchronous belt transmission, sprockets with chain output, etc. In synchronous belt conveyor lines, synchronous pulleys are generally set at both ends of the profile, and the ends of the profiles are separately provided with support structures for supporting synchronous pulleys. The synchronous belt is wound around two synchronous pulleys, one of which is actively rotated by the drive mechanism, and the other synchronous pulley is driven to rotate under the transmission of the synchronous belt, and the synchronous belt body is used for material transportation.

[0003] In the prior art, patent publication number CN202642712U discloses a synchronous pulley tensioning device for a solar photovoltaic module conveyor, wherein a first end plate and a second end plate are provided at the end of a profile, and the first end plate and the second end plate serve as supporting structures of the synchronous pulley assembly, and are metal sheet metal parts, so the cost is high; in addition, when a side panel is installed and fixed to the profile, four screws need to be locked, and two side panels need to be locked with eight screws. For a conveyor line with a larger conveying width, multiple profile brackets need to be arranged at intervals, and the above-mentioned synchronous pulley support structure needs to be arranged at both ends of each profile bracket. In this case, when installing the support structure on a conveyor line, a large number of screws need to be locked, and the installation cost is high. On the other hand, the installation is time-consuming and labor-intensive, and the efficiency is low.

[0004] The prior art patent publication number CN204938164U discloses an adjustable belt conveyor, whose active end is used to support the supporting structure of the active pulley assembly and is also made of metal sheet metal. Two side plates are respectively fixed to the profile bracket by four screws. When assembling the active pulley and the main shaft, it is necessary to first put one end of the synchronous belt on the active pulley, and then put the active pulley between the two side plates, and align the center hole of the synchronous pulley with the main shaft perforation on the side plate, and then pass the main shaft through the side plate perforation and the center hole of the active pulley. The assembly is inconvenient and inefficient. In addition, the return belt body of the synchronous belt and the synchronous belt at the end of the pulley are exposed to the outside, which poses a great safety hazard.

[0005] Therefore, it is necessary to provide a new active end support structure of a conveyor line to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0038] Embodiment 1:

[0039] Please refer to Figure 1-Figure 6, this embodiment is an active end support structure 100, which is an injection molding structure, replacing the original metal sheet metal parts to reduce the production cost.

[0040] The active end support structure 100 of this embodiment comprises a front side plate portion 4, a left side plate portion 1, a right side plate portion 2 and a bottom plate portion 9. The left side plate portion 1 and the right side plate portion 2 are arranged opposite to each other, the left side plate portion 4 is adjacent to the left side plate portion 1, and the right side is adjacent to the right side plate portion 2; the bottom plate portion 9 is arranged at the bottom and located between the left side plate portion 1 and the right side plate portion 2.

[0041] A spindle through hole 11 is provided on both the left plate portion 1 and the right plate portion 2. The spindle through hole 11 includes a hole seat 111 and an introduction slot 112. The hole seat 111 is used to support the spindle. The introduction slot 112 is recessed downward from the top of the side plate to the hole seat 111. The slot width of the introduction slot 112 is greater than the spindle diameter so that the spindle can be placed into the hole seat 111 through the introduction slot 112 from above, which is convenient for the installation of the spindle.

[0042] When the main shaft is installed in the hole seat 111 , in order to assist in limiting the main shaft in the up and down directions and improve the aesthetics of the active end support structure 100 , the active end support structure 100 further has two snap plugs 3 , which are installed in the introduction slots 112 .

[0043] In order to improve the position stability of the snap plug 3 in the introduction slot 112, on the one hand, the introduction slot 112 has a first section and a second section in sequence along the slot depth direction, the slot width of the first section is greater than the slot width of the second section, forming a step structure; the snap plug 3 is matched with a plugging portion 31 and a blocking portion 32, after the snap plug 3 is inserted into the introduction slot 112, the plugging portion 31 fills the space of the first section, the blocking portion 32 fills the space of the second section, and the plugging portion 31 is located on the step structure to achieve insertion depth positioning; on the other hand, a vertically extending limiting groove 113 is provided on the inner wall of the introduction slot 112 located in the second section, and a limiting convex strip 33 matching the limiting groove 113 is provided on the blocking portion 32 of the snap plug 3. Two limiting grooves 113 are provided, respectively located on the two slot wall surfaces of the introduction slot 112, and two corresponding limiting convex strips 33 are provided, respectively located on the front surface and the rear surface of the blocking portion 32. In another embodiment, a limiting convex strip structure may be provided on the two groove wall surfaces of the introduction groove 112 , and a limiting groove structure cooperating therewith may be provided on the blocking portion 32 .

[0044] At least four mounting holes 41 are provided on the front side plate 4, which correspond to the threaded holes at the ends of the conveyor profile bracket. The active end support structure 100 is locked and fixed on the conveyor profile bracket by screws passing through the mounting holes 41 and screwed into the threaded holes. The active end support structure 100 can be installed and fixed on the conveyor profile bracket with only four screws. Compared with the original two side plates that require a total of eight screws for assembly and fixation, the number of screws is reduced and the installation efficiency is improved.

[0045] In order to improve the installation efficiency of the active end support structure 100 and the conveyor line profile bracket, a plurality of positioning protrusions 42 are provided on the front side plate 4 to cooperate with the internal strip grooves of the conveyor line profile bracket to achieve rapid positioning.

[0046] A nut embedding groove 12 is also provided on the inner surface of the left plate portion 1 or the right plate portion 2, and a nut 13 is embedded in the nut embedding groove 12 to facilitate the fixed installation of the bearing seat.

[0047] The space between the left plate portion 1 and the right plate portion 2 forms a receiving cavity 5 for receiving the driving pulley assembly and for rotating the same. The bottom plate portion 9 constitutes the bottom enclosure of the receiving cavity 5, and the front side plate portion 4 constitutes the front side enclosure of the receiving cavity, which can prevent the bottom of the synchronous belt from being exposed when it is wound around the driving pulley assembly, thereby improving safety. A first opening 51 is formed on the surface of the active end support structure 100 to facilitate the active pulley assembly to enter the receiving cavity 5. The first opening 51 extends backward from the top surface of the active end support structure 100 near the front side plate portion 4 to the rear side surface of the active end support structure 100.

[0048] The active end support structure 100 is provided with a support plate portion 6 at the front end of the first opening 51 and a baffle plate portion 7 at the rear end. A holding block 8 is provided on the inner wall surface of the left plate portion 1 and the right plate portion 2 near the rear side of the support plate portion 6.

[0049] The support plate portion 6 can make up for the bottom support of the synchronous belt on the extension line of the conveyor line profile bracket, minimize the suspended section of the synchronous belt, avoid conveying bumps, and improve conveying stability.

[0050] In order to increase the service life of the synchronous belt and reduce wear, the conveyor line used in this embodiment is planned to set a steel belt under the synchronous belt conveyor belt body, and the holding block 8 is used to hold and fix the end of the steel belt to facilitate the fixed installation of the steel belt.

[0051] In order to facilitate the installation of the driving pulley assembly into the accommodating cavity 5, the present embodiment forms a first opening 51 on the driving end support structure 100. However, due to the setting of the first opening 51, when the synchronous belt bypasses the driving pulley assembly for the return trip, there will be a safety hazard at the lower outer part of the driving pulley assembly. The operator may be careless in operation and his fingers may be rolled into the driven end support member 23 from the bottom of the first opening 51 along with the synchronous belt, causing the fingers to be stuck on his hands. Therefore, in order to solve the above safety hazard problem, the present embodiment sets a baffle plate portion 7, which is used to reduce the opening size at the lower rear side of the driving pulley assembly to prevent the operator's fingers from being rolled in.

[0052] In order to facilitate the return belt body of the synchronous belt to enter the interior of the conveyor line profile bracket from the accommodating cavity 5, a second opening 43 is provided on the front side plate 4 for the synchronous belt to pass through. The second opening 43 allows the synchronous belt to enter and exit the accommodating cavity 5 on the one hand, and allows the return belt body of the synchronous belt to enter the accommodating cavity 5 from outside the active end support structure 100 on the other hand.

[0053] In one embodiment, the active end support structure 100 is an integral injection-molded structure.

[0054] In another embodiment, the active end support structure 100 can also be formed by assembling two plastic parts to form a plastic combination structure. For example, it includes a first plastic part and a second plastic part, and the right side plate part 2, the front side plate part 4, the support plate part 6 and the baffle plate part 7 are designed as an integrally formed plastic part structure to constitute the first plastic part; the left side plate part 1 constitutes the second plastic part; the first plastic part is provided with a plurality of threaded holes 14, and the second plastic part is assembled with the first plastic part by screwing into the threaded holes 14 to form the active end support structure 100. For another example, it includes a third plastic part and a fourth plastic part, and the left side plate part 1, the front side plate part 4, the support plate part 6 and the baffle plate part 7 are designed as an integrally formed plastic part structure to constitute the third plastic part; the right side plate part 2 constitutes the fourth plastic part; the third plastic part is provided with a plurality of third threaded holes (not marked in the figure), and the fourth plastic part is assembled with the third plastic part by screwing into the third threaded holes to form the active end support structure 100.

[0055] When the active end support structure 100 is an integral injection molding structure, the second opening 43 has a vertical belt passage 431 that vertically passes upward to the top of the front side plate, and the opening is upward. The return belt body of the synchronous belt can be placed downward from the opening (vertical belt passage 431) of the second opening 43 into the range of the second opening 43, and then one end of the return belt body is wound around the active pulley assembly, and the return belt body passes through the second opening 43 and the internal cavity of the conveyor line profile bracket and returns to the driven pulley assembly end.

[0056] When the active end support structure 100 is a plastic composite structure, the second opening 43 on the front side plate portion 4 is a U-shaped opening structure opening toward the right side plate portion 2 (when the right side plate portion 2 is the fourth plastic part) or a U-shaped opening structure opening toward the left side plate portion 1 (when the left side plate portion 1 is the second plastic part). The return belt body of the synchronous belt can move horizontally from the opening of the second opening 43 to the range of the second opening 43, and then pass through the second opening 43 longitudinally; when one end of the synchronous belt is wound around the active pulley assembly, its return belt body can pass through the second opening 43 and the internal cavity of the conveyor line profile bracket to return to the driven pulley assembly end.

[0057] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
