Description

Technical Field

[0001] The present application relates to the technical field of conveying equipment, and in particular to a sprocket transmission mechanism. Background Art

[0002] Chain conveyors use chains as traction and carriers to transport materials. The chains can be ordinary sleeve roller conveyor chains or various other special chains (such as accumulation chains, double-speed chains). Chain conveyors have large conveying capacity and are mainly used to convey pallets, large turnover boxes, etc. The conveyor chain has various structural forms and a variety of accessories, which makes it easy to achieve accumulation and conveying. It can be used as an assembly production line or for material storage and transportation.

[0003] In the process of cargo transmission, the chain-driven conveyor mainly transmits the goods through the chain device. The chain is meshed on the sprocket. Some sprocket structures will be connected to the reduction box, which is used to adjust the running speed of the sprocket structure. When the reduction box is connected to the conveyor chain, it is easy to offset and wear for a long time. Normal wear will gradually stretch the chain, and it is easy to jump teeth and lose teeth, resulting in the disconnection between the reduction box and the chain. Summary of the invention

[0004] In order to improve the above problems, the present application provides a sprocket transmission mechanism.

[0005] The sprocket transmission mechanism provided in this application adopts the following technical solution:

[0006] A sprocket transmission mechanism comprises a connecting track, a cross chain, a reduction gearbox and a conveying chain; the cross chain is slidably connected to the connecting track, and the cross chain is confined within the connecting track; the conveying chain is connected to the reduction gearbox, and a plurality of connecting members are provided on the conveying chain; a plurality of the connecting members are installed on the conveying chain at preset intervals and plugged into the connecting track; the connecting members cooperate with the cross chain so that the conveying chain pushes the cross chain to move along the connecting track through the connecting members when moving.

[0007] By adopting the above technical solution, the conveying chain is driven to rotate through the reduction box, and the connecting piece on the conveying chain is inserted from the bottom of the connecting track into the connecting track. As the conveying chain drives the connecting piece to rotate, the connecting piece and the cross chain are pressed tightly and pushed when pressed tightly. The cross chain is limited by the connecting track and cannot be separated from the connecting track. When driven by the connecting piece, the cross chain moves along the connecting track and cannot be separated from the connecting track during the movement, so that derailment or tooth disengagement will not occur.

[0008] Optionally, the cross chain includes a plurality of cross chains, there is a spacing distance between adjacent cross chains, and the connecting member is located within the spacing distance.

[0009] By adopting the above technical solution, the spacing distance between adjacent cross chains allows the connector to be inserted into the spacing, and multiple connectors can be inserted into multiple spacings respectively, so that the cross chain is pushed by multiple connectors at the same time during transportation, making the movement more stable.

[0010] Optionally, the size of the connecting member matches the spacing distance between adjacent cross chains.

[0011] By adopting the above technical solution, the connecting piece can be inserted into the interval, so that no matter when the connecting piece is driven by the conveying chain to push the cross chain in any direction, it can provide a more stable pushing effect.

[0012] Optionally, an arc groove is provided on the connecting member, and the arc groove matches the surface shape of the cross chain.

[0013] By adopting the above technical solution, the cross chain can be extended into the arc groove. When the connecting part is driven by force to move the cross chain, the deviation of the cross chain can be reduced, so that the movement stability is stronger and the phenomena of tooth disengagement and derailment can be further reduced.

[0014] Optionally, the connecting member includes a first connecting segment, a second connecting segment and a sliding portion; the sliding portion is connected to the conveying chain; the first connecting segment and the second connecting segment are separated, and the first connecting segment and the second connecting segment are both slidably connected to the sliding portion; an adjusting member is provided between the first connecting segment and the second connecting segment.

[0015] By adopting the above technical solution, when the cross chain becomes worn, loose or stretched, the adjustment member is used to adjust the distance between the first connecting segment and the second connecting segment and the chain for the loose or stretched part, so that the first connecting segment and the second connecting segment can provide support for the chain, reduce the chain from further stretching, reduce looseness, and thus extend the service life.

[0016] Optionally, a first thread groove is provided on the first connecting section; a second thread groove is provided on the second connecting section; an external thread is provided on the adjusting member, and the directions of the external threads at both ends of the adjusting member are opposite; the adjusting member is threadedly connected to the first thread groove and the second thread groove, and the thread directions of the first thread groove and the second thread groove are opposite.

[0017] By adopting the above technical solution, when it is necessary to adjust the position of the first connecting segment and the second connecting segment, the external thread on the adjusting segment rotates along with the first thread groove and the second thread inner groove by rotating the adjusting member. During the rotation, the first connecting segment and the second connecting segment are driven to move along the sliding portion due to the threaded connection, thereby adjusting the position of the first connecting segment and the second connecting segment to adapt to the distance between adjacent cross chains of the cross chain.

[0018] Optionally, a rotating portion is arranged in the middle of the adjusting member.

[0019] By adopting the above technical solution, the rotating part is used to provide a fulcrum for the rotating adjustment member, so that the adjustment method of the adjustment member is easier and more convenient.

[0020] Optionally, the rotating part is provided with anti-slip grooves.

[0021] By adopting the above technical solution, the anti-skid pattern provides an anti-skid effect, which can increase the friction of the rotating part, so as to avoid hand slipping when the rotating part rotates the adjusting member.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The conveyor chain is driven to rotate by the reduction box, and the connector on the conveyor chain is inserted from the bottom of the connecting track into the connecting track. As the conveyor chain drives the connector to rotate, the connector and the cross chain are pressed tightly and pushed when pressed tightly. The cross chain is limited by the connecting track and cannot be separated from the connecting track. When driven by the connector, the cross chain moves along the connecting track and cannot be separated from the connecting track during the movement, so there will be no derailment or tooth loss.

[0024] 2. The spacing between adjacent cross chains allows the connector to be inserted into the spacing, and multiple connectors can be inserted into multiple spacings respectively, so that the cross chain is pushed by multiple connectors at the same time during transportation, making the movement more stable;

[0025] 3. The connector can be inserted into the gap, so that no matter the connector is driven by the conveyor chain and pushes the cross chain in any direction, it can provide a more stable pushing effect;

[0026] 4. When the cross chain becomes worn, loose or stretched, use the adjusting piece to adjust the distance between the first connecting section and the second connecting section and the chain for the loose or stretched part, so that the first connecting section and the second connecting section can provide support for the chain, reduce the chain from further stretching, reduce looseness, and thus extend the service life.

In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0039] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0040] The embodiment of the present application discloses a sprocket transmission mechanism.

[0041] A sprocket transmission mechanism, reference Figure 1 and Figure 2 As shown, it includes a connecting track 1, a cross chain 2, a reduction box 3 and a conveying chain 4; the cross chain 2 is connected to the external transport equipment, and the cross chain 2 is used to drive the external water conveying equipment to operate. The cross chain 2 is slidably connected to the connecting track 1, and the cross chain 2 is restricted in the connecting track 1, so that when the cross chain 2 is driven, it moves along the connecting track 1 and drives the external conveying equipment to move along the connecting track 1, wherein the bottom of the connecting track 1 is provided with an insertion port (reference Figure 2 as shown).

[0042] In the figure, the connecting track 1, the cross chain 2 and the reduction box 3 are separated from each other for clear observation.

[0043] The conveyor chain 4 is connected to the reduction box 3, and a number of connecting parts 5 are arranged on the conveyor chain 4. The reduction box 3 is used to provide drive for external conveying equipment. A box body is arranged outside for protection (the box body is hidden), and a motor and a reduction structure are arranged inside. The reduction structure is connected to the conveyor chain 4, so that the motor drive can utilize the reduction structure to drive the conveyor chain 4 to rotate.

[0044] The connecting member 5 can be a connecting protrusion connected to the conveying chain 4. Several connecting members 5 are installed on the conveying chain 4 at preset intervals, so that when the conveying chain 4 is driven to rotate by the reduction box 3, it can drive several connecting members 5 to rotate.

[0045] The connector 5 is plugged into the connecting track 1 so that the connector 5 can cooperate with the cross chain 2, that is, the connector 5 can extend into the connecting track 1 from the insertion opening at the bottom of the connecting track 1, so that the conveying chain 4 pushes the cross chain 2 to move along the connecting track 1 through the connecting protrusion when moving.

[0046] Specifically, the conveying chain 4 is driven to rotate by the reduction gear box 3, and the connecting piece 5 on the conveying chain 4 is inserted from the bottom of the connecting track 1 into the connecting track 1. As the conveying chain 4 drives the connecting piece 5 to rotate, the connecting piece 5 is pressed against the cross chain 2 and pushed when pressed. The cross chain 2 is limited by the connecting track 1 and cannot be separated from the connecting track 1. When driven by the connecting piece 5, the cross chain 2 moves along the connecting track 1, and cannot be separated from the connecting track 1 during the movement, so that derailment or tooth disengagement will not occur.

[0047] Among them, the reduction box 3 has a spring adjustment structure, that is, the elasticity of the spring is used to tighten the conveying chain 4, thereby reducing the loss of the conveying chain 4 during long-term operation, so that the connecting part 5 can move more stably with the conveying chain 4 to provide stable driving operation of the cross chain 2.

[0048] For further reference, Figure 3 and Figure 4 As shown, there is a spacing distance between adjacent cross chains 21 of the cross chain 2, and the connecting member 5 is located within the spacing distance. The cross chain 2 is composed of a plurality of connecting columns, a pin shaft, and a cross-shaped chain that are movably connected to each other. Therefore, the cross chain 2 includes a plurality of chains. Through the spacing distance between adjacent cross chains 2, the connecting member 5 can be inserted into the spacing, and a plurality of connecting members 5 can be respectively inserted into a plurality of spacings, so that the cross chain 2 is pushed by a plurality of connecting members 5 at the same time during transportation, making the movement more stable.

[0049] Further, refer to Figure 5 As shown, the size of the connecting member 5 matches the spacing distance between adjacent cross chains 21 of the cross chain 2, that is, the length of the connecting member 5 is the same or approximately the same as the spacing distance between adjacent cross chains 21, so that the connecting member 5 can be inserted into the spacing just right, so that no matter whether the connecting member 5 is driven by the conveying chain 4 to push the cross chain 21 in any direction, it can provide a more stable pushing effect.

[0050] At the same time, when the adjacent cross chain 21 is pushed, the force of the previous chain can resist one end of the connecting member 5, so that the force of the chain is balanced, the pulling phenomenon is reduced, the chain wear is caused, and the elongation and the like are avoided.

[0051] Further, refer to Figure 5 or Figure 6As shown, an arc groove 51 is provided on the connecting member 5, and the arc groove 51 is matched with the surface shape of the cross chain 21. The surface corners of the cross chain 21 are chamfered and have an arc shape. Therefore, the arc groove 51 is provided on the surface of the connecting member 5 so that the cross chain 21 can extend into the arc groove 51. When the connecting member 5 is driven by force to move the cross chain 21, the deviation of the cross chain 21 can be reduced, so that the movement stability is stronger, and the phenomena of tooth stripping and derailment are further reduced.

[0052] In some embodiments, reference Figure 6 As shown, the connecting member 5 includes a first connecting segment 52, a second connecting segment 53 and a sliding portion 54. The first connecting segment 52 and the second connecting segment 53 are separated, and the first connecting segment 52 and the second connecting segment 53 are both slidably connected to the sliding portion 54. The sliding portion 54 is connected to the conveying chain 4. A sliding block can be used, and a limiting groove can be set on the sliding block. The first connecting segment 52 and the second connecting segment 53 are both provided with a limiting protrusion. The limiting protrusion and the limiting groove are used to make the first connecting segment 52 and the second connecting segment 53 move along the sliding portion 54, and the first connecting segment 52 and the second connecting segment 53 are separately set, so that the first connecting segment 52 and the second connecting segment 53 can each move along the sliding portion 54 without being affected by each other.

[0053] An adjusting member 6 is provided between the first connecting segment 52 and the second connecting segment 53 , and the adjusting member 6 is used to adjust the distance between the first connecting segment 52 and the second connecting segment 53 to adapt to the distance between adjacent cross chains 21 of different cross chains 2 .

[0054] At the same time, when the cross chain 21 is worn, loosened or stretched, the adjustment member 6 can be used to adjust the distance between the first connecting segment 52 and the second connecting segment 53 and the chain for the loosened or stretched part, so that the first connecting segment 52 and the second connecting segment 53 can provide support for the chain, reduce the chain from further stretching, reduce looseness, and thus extend the service life.

[0055] Furthermore, a first thread groove 521 is provided on the first connecting section 52; a second thread groove 531 is provided on the second connecting section 53, and an external thread is provided on the adjusting member 6, which is threadedly connected to the first thread groove 521 and the second thread groove 531 by means of the external thread, and the external threads at both ends of the adjusting member 6 are in opposite directions, and the thread directions of the first thread groove 521 and the second thread groove 531 are in opposite directions, and are adapted to the external threads at both ends of the adjusting member 6.

[0056] The adjusting member 6 can adopt a threaded column, and the threads at both ends of the threaded column are opposite, so that when the adjusting member 6 rotates along the first thread groove 521 and the second thread groove 531, it can push or retract the first connecting section 52 and the second connecting section 53 to the two sides of the sliding part 54, thereby adjusting the position of the first connecting section 52 and the second connecting section 53.

[0057] Specifically, when it is necessary to adjust the position of the first connecting segment 52 and the second connecting segment 53, the adjusting member 6 is rotated so that the external thread on the adjusting member 6 rotates along with the first thread groove 521 and the second thread inner groove. During the rotation, the first connecting segment 52 and the second connecting segment 53 are driven to move along the sliding portion 54 due to the threaded connection, thereby adjusting the position of the first connecting segment 52 and the second connecting segment 53 to adapt to the distance between adjacent cross chains 21 of the cross chain 2 and improve adaptability.

[0058] Furthermore, a rotating portion 61 is provided in the middle of the adjusting member 6. The rotating portion 61 can be a rotating ring or a rotating wheel. The rotating ring or the rotating wheel provides a fulcrum for rotating the adjusting member 6, making the adjustment of the adjusting member 6 easier and more convenient.

[0059] Among them, reference Figure 6 As shown, a plurality of anti-skid grooves are provided on the rotating ring, which provide an anti-skid effect and can increase the friction of the rotating part 61, so that the rotating part 61 can avoid hand slipping when the adjusting member 6 is rotated, especially when the chain is lubricated with lubricating oil or other items.

[0060] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
