Description

Technical Field

[0001] The invention relates to the technical field of gypsum board conveying, and in particular to a gypsum board roller conveying system with a tooth skipping protection function. Background Art

[0002] During the production process of gypsum boards, the gypsum boards are transported through open rollers. The transmission method of the open roller is to drive the rollers to rotate and transport through a whole roller chain or a toothed chain.

[0003] A toothed chain is usually used in the transmission structure instead of a roller chain, and a separate supporting sprocket and tensioner are installed in the middle of the toothed chain. The independent spring support inside the tensioner tightens the toothed chain downward in real time to ensure a good tension of the chain, improve transmission efficiency, and reduce the misalignment of the chain and gear meshing. There is no need to manually adjust the roller position and chain length to ensure the tension of the chain.

[0004] However, when the existing chain transmission technology is used for a long time, the chain and gear may be misaligned. The misalignment of the chain and gear changes the interaction surface between the chain and the gear. The contact between different parts causes impact and wear between the chain and the gear, which not only affects the transmission work, but also causes irreversible damage to the chain and gear themselves. Summary of the invention

[0005] To this end, the present invention provides a gypsum board roller conveyor system with a tooth skipping protection function, which effectively solves the problem in the prior art that the misalignment of the chain and the gear causes impact wear between the chain and the gear, affects the transmission work, and causes damage to the chain and the gear themselves.

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] As Figure 1 shown, the present invention provides a gypsum board roller conveyor system with a skip tooth protection function, which has a tooth-shaped chain drive structure 1, a tooth-shaped chain limiting guide rail 2, a tooth retraction drive structure 3, and a support surface forming structure 4. The above structures are all arranged on the side of the roller conveyor device 5.

[0054] Among them, the tooth-shaped chain drive structure 1 is connected to the side of the roller conveyor device 5. The tooth-shaped chain drive structure 1 has a tooth-shaped chain 11 and a driving sprocket 12 arranged on the tooth-shaped chain 11. The driving sprocket 12 is used to drive the roller conveyor device 5 to rotate forward for transportation, and is in transmission connection with the adjacent conveyor roller 51 on the roller conveyor device 5 through the tooth-shaped chain 11.

[0055] The tooth-shaped chain limiting guide rail 2 is arranged on the tooth-shaped chain transmission structure 1. The tooth-shaped chain limiting guide rail 2 is used to limit a part of the tooth-shaped chain 11 that meshes with the transmission sprocket 12, so that a tightly fitting meshing surface is formed between the tooth-shaped chain 11 and the transmission sprocket 12.

[0056] The tooth retraction driving structure 3 is arranged on the transmission sprocket 12. The tooth retraction driving structure 3 is used to drive the meshing teeth 13 of the transmission sprocket 12 that mesh with the tooth-shaped chain 11 to retract into the transmission sprocket 12 and rotate at the same angular velocity of rotation as the transmission sprocket 12, so that the meshing teeth 13 remain relatively stationary with respect to the transmission sprocket 12 in the retracted state.

[0057] The support surface forming structure 4 is installed on the transmission sprocket 12. The support surface forming structure 4 is provided with a support follower 41. The support follower 41 faces the tooth-shaped chain 11 and forms a follower support surface. The support follower 41 moves outward during the retraction process of the meshing teeth 13 to drive the follower support surface to move to abut against the tooth-shaped chain 11, and the tooth end of the tooth-shaped chain 11 presses inward on the follower support surface to form a concave surface, so as to drive the support follower 41 to rotate synchronously through the tooth-shaped chain 11.

[0058] Among them, the tooth-shaped chain limiting guide rail 2 limits a part of the tooth-shaped chain 11 that meshes with the transmission sprocket 12, so that the tooth-shaped chain 11 maintains its original running track when the meshing teeth 13 retract, and the tooth-shaped chain 11 and the meshing teeth 13 move away from each other.

[0059] In the above-mentioned invention embodiment, by limiting a part of the tooth-shaped chain 11 that meshes with the transmission sprocket 12 through the tooth-shaped chain limiting guide rail 2, the situation of inaccurate meshing between the tooth-shaped chain 11 and the transmission sprocket 12 is reduced. And when the meshing between the tooth-shaped chain 11 and the transmission sprocket 12 is inaccurate, the tooth retraction driving structure 3 drives the meshing teeth 13 of the transmission sprocket 12 that mesh with the tooth-shaped chain 11 to retract into the transmission sprocket 12 to avoid the interaction between the transmission sprocket 12 and the tooth-shaped chain 11, and protects the transmission sprocket 12 and the tooth-shaped chain 11 when the meshing between the tooth-shaped chain 11 and the transmission sprocket 12 is inaccurate. In addition, the support follower 41 is also driven to move the follower support surface to abut against the tooth-shaped chain 11, and the tooth-shaped chain 11 drives the support follower 41 to rotate synchronously, so that the tooth-shaped chain 11 and the corresponding transmission sprocket 12 continue to move, avoiding affecting the transmission work.

[0060] In the present invention, it is transported by rotation through the third section roller conveyor device 5 of the tooth-shaped chain transmission structure 1. The tooth-shaped chain transmission structure 1 of the present invention adopts the following preferred embodiments, such as Figure 2As shown in the figure, the toothed chain drive structure 1 includes a drive shaft 14 provided on a conveying roller 51 and a tensioning sprocket 15 provided inside the toothed chain 11; a transmission sprocket 12 is coaxially connected to the drive shaft 14, adjacent transmission sprockets 12 are connected by the toothed chain 11, the tensioning sprocket 15 is provided inside the toothed chain 11, a rotating shaft bracket 16 and a mounting seat 17 are provided on the side of the tensioning sprocket 15, the rotating shaft bracket 16 is rotatably provided on the mounting seat 17, and the tensioning sprocket 15 is rotatably provided at the end of the rotating shaft bracket 16.

[0061] In the above embodiment, the rotation of the transmission sprocket 12 drives the toothed chain 11 to run forward, thereby driving the connected transmission sprockets 12 to rotate, driving the drive shaft 14 to rotate and thus driving the corresponding conveying roller 51 to rotate for transportation. In addition, the tensioning sprocket 15 plays a role in maintaining the tension of the toothed chain 11, and the toothed chain 11 always remains in a tensioned state during the transportation process, greatly reducing the situation of tooth skipping between the toothed chain 11 and the transmission sprocket 12.

[0062] The main structure of the toothed chain 11 in the present invention is as follows, as Figure 5 shown, the toothed chain 11 is composed of tooth link plates 111, connecting plates 112 and external meshing tooth plates 113; a plurality of tooth link plates 111, connecting plates 112 and external meshing tooth plates 113 are provided, adjacent tooth link plates 111 are connected by connecting plates 112, and a guide shaft 114 is provided at the connection, and the external meshing tooth plates 113 are provided outside the guide shaft 114.

[0063] Among them, the external meshing tooth plates 113 are meshed with the transmission sprockets 12, the forward transportation of the external meshing tooth plates 113 can drive the transmission sprockets 12 to rotate, and the transmission sprockets 12 can also drive the external meshing tooth plates 113 to transport forward. In addition, the toothed chain limiting guide rail 2 of the present invention mainly realizes the limitation of the toothed chain 11 by limiting the guide shaft 114.

[0064] In the present invention, the toothed chain limiting guide rail 2 limits the toothed chain 11. The toothed chain limiting guide rail 2 of the present invention mainly adopts the following preferred embodiments, as Figure 3 、 Figure 4 and Figure 6 shown, the toothed chain limiting guide rail 2 includes a limiting frame 21 provided on the side of the connection between the toothed chain 11 and the transmission sprocket 12, a transmission channel 22 provided inside the limiting frame 21, and limiting grooves 23 provided on the inner side walls of both sides of the transmission channel 22; the toothed chain 11 passes through the transmission channel 22, and the guide shaft 114 is slidably provided in the limiting grooves 23.

[0065] In the above embodiment, during the connection and transmission between the toothed chain 11 and the transmission sprocket 12, the toothed chain 11 passes through the transmission channel 22, and the guide rail 114 slides in the limiting grooves 23.

[0066] Since the internal structure of the toothed chain 11 is basically rotationally connected and relatively unstable, in order to enable the guide rail 114 to enter the limiting groove 23 at the beginning, the present invention also makes the following design, such as Figure 3 , Figure 4 and Figure 6 As shown, both ends of the guide shaft 114 are in contact with the inner wall of the limiting groove 23; an inlet groove 24 is provided at the inlet end of the limiting groove 23, the inlet groove 24 is communicated with the limiting groove 23, and the width of the inlet groove 24 is greater than the width of the limiting groove 23.

[0067] In the above embodiment, since the opening of the inlet groove 24 is relatively large, the guide shaft 114 can smoothly enter the inlet groove 24 and then gradually enter the limiting groove 23. During the process of the guide shaft 114 sliding in the limiting groove 23, the toothed chain 11 is limited. During this process, even if the meshing gear teeth 13 are disengaged from the toothed chain 11, the running track of the toothed chain 11 will not change. Therefore, the toothed chain limiting guide rail 2 limits the part of the toothed chain 11 meshing with the driving sprocket 12, so as to keep the toothed chain 11 in its original running track when the meshing gear teeth 13 retract, and to make the toothed chain 11 and the meshing gear teeth 13 move away from each other. When the meshing gear teeth 13 are disengaged from the toothed chain 11, the toothed chain 11 continues to perform the conveying action along the original track under the drive of another driving sprocket 12.

[0068] In order to install the tooth retraction driving structure 3 and the supporting follower component 41, the present invention also makes the following design. An installation embedding groove 18 is provided on the driving sprocket 12, and the meshing gear teeth 13 pass through the installation embedding groove 18; an installation clamping groove 19 is provided between adjacent installation embedding grooves 18, and the supporting follower component 41 is installed in the installation clamping groove 19.

[0069] The tooth retraction driving structure 3 of the present invention drives the meshing gear teeth 13 meshing with the toothed chain 11 on the driving sprocket 12 to retract into the driving sprocket 12 and rotate at the same rotational angular velocity as the driving sprocket 12, so that the meshing gear teeth 13 remain relatively stationary with respect to the driving sprocket 12 in the retracted state. The tooth retraction driving structure 3 of the present invention adopts the following preferred embodiments, such as Figure 7 and Figure 8 As shown, the tooth retraction driving structure 3 includes a connecting shaft seat 31 arranged inside the driving sprocket 12, a central shaft 32 arranged on the connecting shaft seat 31, a driving disk 33 rotatably arranged on the central shaft 32, and a retraction shaft 34 connected to the meshing gear teeth 13; the connecting shaft seat 31 is coaxially connected with the driving sprocket 12, and a sliding groove 35 is provided on the connecting shaft seat 31, and the retraction shaft 34 is slidably arranged in the sliding groove 35.

[0070] In the above embodiment, the retraction shaft 34 can move on the sliding groove 35. When the retraction shaft 34 moves inwards in the sliding groove 35, it drives the meshing gear teeth 13 to move inwards, and when the retraction shaft 34 moves outwards in the sliding groove 35, it drives the meshing gear teeth 13 to move outwards.

[0071] To drive the sliding of the retractable shaft 34 in the sliding groove 35, the present invention also makes the following design. A central groove 36 is provided inside the connecting shaft seat 31, and the sliding groove 35 communicates with the central groove 36. The end of the retractable shaft 34 is rotatably connected to a first rotating shaft 37, and the end of the first rotating shaft 37 is rotatably connected to the drive disk 33 away from the central axis through a connecting bolt 38. The first rotating shaft 37 is away from the sliding groove 35.

[0072] In the above embodiment, the rotation of the central shaft 32 drives the rotation of the drive disk 33, thereby driving the rotation of the first rotating shaft 37 and gradually moving away from the sliding groove 35. During this process, the end of the first rotating shaft 37 also drives the retractable shaft 34 to gradually move closer to the drive disk 33, thereby driving the retractable shaft 34 to move inward in the sliding groove 35. To drive the rotation of the central shaft 32, the present invention also makes the following design. A follower shaft seat 39 is disposed opposite to the side of the transmission sprocket 12. A first driving motor 310 is provided inside the follower shaft seat 39. The central shaft 32 is connected to the output end of the first driving motor 310. The follower shaft seat 39 is connected to the transmission sprocket 12 and rotates coaxially.

[0073] In the above embodiment, the retraction process of the meshing gear teeth 13 is as follows. The follower shaft seat 39 and the transmission sprocket 12 rotate synchronously, so the follower shaft seat 39 and the transmission sprocket 12 remain relatively stationary. The first driving motor 310 drives the rotation of the central shaft 32, thereby driving the rotation of the drive disk 33. The drive disk 33 drives the rotation of the first rotating shaft 37 and gradually moves away from the sliding groove 35. During this process, the end of the first rotating shaft 37 also drives the retractable shaft 34 to gradually move closer to the drive disk 33, thereby driving the retractable shaft 34 to move inward in the sliding groove 35. During the inward movement of the retractable shaft 34, the meshing gear teeth 13 are driven to move inward. Although they do not completely enter the interior of the transmission sprocket 12, they are away from the tooth-shaped chain 11, avoiding the interaction between the meshing gear teeth 13 and the transmission sprocket 12.

[0074] In the present invention, the support follower member 41 faces the tooth-shaped chain 11 and forms a follower support surface. The support follower member 41 can move outward during the retraction process of the meshing gear teeth 13 to drive the follower support surface to move to abut against the tooth-shaped chain 11, and the tooth end of the tooth-shaped chain 11 forms an inner concave surface by inward pressing on the follower support surface, so as to drive the support follower member 41 to rotate synchronously through the tooth-shaped chain 11. The support follower member 41 of the present invention adopts the following preferred embodiment, such as Figure 7 and Figure 8 As shown, the support follower member 41 includes a telescopic shaft seat 411 disposed in the installation card slot 19, a rubber outer seat 412 disposed on the outer end surface of the telescopic shaft seat 411, and a telescopic shaft rod 413 connected to the inner side of the telescopic shaft seat 411. The rubber outer seat 412 fits with the opening part of the installation card slot 19, and the movement directions of the telescopic shaft seat 411 and the retractable shaft 34 are opposite.

[0075] In the above embodiment, the telescopic shaft seat 411 is movable, and in the initial state, the outer rubber outer seat 412 and the meshing gear teeth 13 form a whole transmission sprocket 12, and the rubber outer seat 412 only contacts the outer meshing tooth plate 113 under normal transmission conditions. After the telescopic shaft seat 411 and the rubber outer seat 412 move outward, the rubber outer seat 412 is gradually squeezed onto the outer meshing tooth plate 113, and the outer meshing tooth plate 113 squeezes the inner concave surface on the rubber outer seat 412. Driven by the outer meshing tooth plate 113, the rubber outer seat 412 can also be driven to rotate at the same time. Therefore, the transmission sprocket 12 can also be driven to rotate as a whole through the toothed chain 11.

[0076] The support surface forming structure 4 of the present invention can drive the supporting follower component 41 to move outward during the retraction process of the meshing gear 13, so as to drive the follower supporting surface to move to abut against the toothed chain 11. Therefore, the support surface forming structure 4 of the present invention also includes the following designs, such as Figure 7 and Figure 8 As shown, a telescopic groove 42 is provided on the connecting shaft seat 31, and the telescopic groove 42 is connected to the central groove 36; the end of the telescopic shaft rod 413 is rotatably connected to the second rotating shaft, and the end of the second rotating shaft is rotatably connected to the driving disk 33 away from the central axis through the connecting bolt 38.

[0077] In the above embodiment, in order to make the telescopic shaft seat 411 move outward when the meshing gear 13 moves inward, it is necessary to rotate the driving plate 33 to drive the first rotating shaft 37 away from the sliding groove 35 and drive the second rotating shaft close to the telescopic groove 42.

[0078] Therefore, the outward movement process of the telescopic shaft seat 411 is that the first driving motor 310 drives the central shaft 32 to rotate, thereby driving the driving disk 33 to rotate, and the driving disk 33 drives the first rotating shaft 37 to rotate and gradually move away from the sliding groove 35. At the same time, the rotation of the driving disk 33 drives the second rotating shaft to rotate and approach the telescopic groove 42, driving the telescopic shaft rod 412 to move in and out of the telescopic groove 42, thereby driving the telescopic shaft seat 411 and the rubber outer seat 412 to move outward, forming extrusion with the external meshing gear plate 113.

[0079] In summary, the main implementation process of the present invention is:

[0080] The conveying roller 51 drives the gypsum board to be transported: the transmission sprockets 12 are driven by each other through the toothed chain 11, and the transmission sprocket 12 drives the conveying roller 51 to rotate through the driving shaft 14 to transport the gypsum board;

[0081] In the case of the chain sprocket of the toothed chain 11 and the driving sprocket 12 skipping teeth: The first driving motor 310 drives the central shaft 32 to rotate, thereby driving the driving disk 33 to rotate. The driving disk 33 drives the first rotating shaft 37 to rotate and gradually move away from the sliding groove 35. The end of the first rotating shaft 37 also drives the retracting shaft 34 to gradually move closer to the driving disk 33, thereby driving the retracting shaft 34 to move inward in the sliding groove 35. During the inward movement of the retracting shaft 34, the meshing gear teeth 13 are driven to move inward away from the toothed chain 11;

[0082] The supporting follower member 41 moves outward and presses against the toothed chain 11: While the first driving motor 310 is driving, the driving disk 33 rotates to drive the second rotating shaft to rotate and approach the telescopic groove 42, driving the telescopic shaft rod 412 to move outward in the telescopic groove 42, thereby driving the telescopic shaft seat 411 and the rubber outer seat 412 to move outward, forming a squeeze with the external meshing tooth plate 113. The transportation of the toothed chain 11 can continue to drive the overall transmission of the driving sprocket 12 through the supporting follower member 41.

[0083] The present invention is mainly applicable to the emergency adoption plan in the case of tooth skipping and cannot be used for a long time. When tooth skipping occurs, it is necessary to dispatch staff to check the corresponding toothed chain 11 and driving sprocket 12. In addition, in the actual application process, it is possible to judge whether tooth skipping occurs by setting a corresponding pressure sensor in the driving sprocket 12 and then analyzing the data of the pressure sensor.

[0084] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
