Description

Technical Field

[0001] This application relates to the field of industrial automation technology, specifically to a plate chain conveyor device. Background Technology

[0002] Plate chain conveyors are mainly used for material handling and conveying. They consist of several key components, including a motor, drive shaft, rollers, and tensioning device. The plate chain conveyor is powered by a series of racks and pinions fixed to a traction chain, using metal plates as the load-bearing structure to transport materials.

[0003] Specifically, the basic working principle of a chain conveyor is that the power of the motor is transmitted to the transmission system, which drives the rollers and sprockets to drive the rack in a cyclical motion, thereby pushing the metal plate fixed on the rack to move and realize the horizontal or inclined conveying of materials.

[0004] However, after prolonged operation, the racks in a plate chain conveyor system can lose tension and become loose. Loose racks may then detach or break during operation, causing the entire conveying system to suddenly stop, thus affecting production continuity and efficiency. Due to the loose racks, transmission capacity and traction will decrease, leading to a reduction in material transport speed, and in severe cases, even transport may stall. Utility Model Content

Detailed Implementation

[0030] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application.

[0031] Plate chain conveyors are mainly used for material handling and conveying. They consist of several key components, including a motor, drive shaft, rollers, and tensioning device. The plate chain conveyor is powered by a series of racks and pinions fixed to a traction chain, using metal plates as the load-bearing structure to transport materials.

[0032] Specifically, the basic working principle of a chain conveyor is that the power of the motor is transmitted to the transmission system, which drives the rollers and sprockets to drive the rack in a cyclical motion, thereby pushing the metal plate fixed on the rack to move and realize the horizontal or inclined conveying of materials.

[0033] However, after prolonged operation, the racks in a plate chain conveyor system can lose tension and become loose. Loose racks may then detach or break during operation, causing the entire conveying system to suddenly stop, thus affecting production continuity and efficiency. Due to the loose racks, transmission capacity and traction will decrease, leading to a reduction in material transport speed, and in severe cases, even transport may stall.

[0034] To address the problem of low material transport efficiency caused by loose racks in plate chain conveyors, see [reference needed]. Figure 1 This application provides a plate chain conveyor device, comprising:

[0035] 1. Housing; 2. Motor; 3. Rack; 4. First connecting shaft; 5. First gear; 6. Second gear; 7. Third gear; 8. Plate chain guide plate; 9. Limiting part.

[0036] The plate chain guide plates 8 are symmetrically arranged on both sides of the housing 1; the rack 3 is sleeved on the plate chain guide plates 8;

[0037] like Figure 2 As shown, the output end of motor 2 is connected to the first gear 5, and the first gear 5 meshes with the second gear 6; the second gear 6 is connected to the first connecting shaft 4.

[0038] The two ends of the first connecting shaft 4 are respectively inserted into the plate chain guide plate 8, and the two ends of the first connecting shaft 4 are respectively connected to the third gear 7, and the third gear 7 meshes with the rack 3;

[0039] like Figure 5 As shown, the plate chain guide plate 8 is provided with a guide groove 81 along its periphery, and the rack 3 includes a plurality of sub-chains 31. Each sub-chain 31 includes a second connecting shaft 311. The two ends of the second connecting shaft 311 are inserted into the guide groove 81 so that the sub-chain 31 is slidably connected to the plate chain guide plate 8.

[0040] The rack 3 is provided with several limiting parts 9 at equal intervals.

[0041] When motor 2 starts, its output drives the first gear 5 to rotate. Since the first gear 5 meshes with the second gear 6, the rotation of the first gear 5 drives the second gear 6 to mesh as well. The shaft hole of the second gear 6 has a notch. When the first connecting shaft 4 is inserted into the shaft hole, the protrusion on the first connecting shaft 4 aligns with the notch, locking the second gear 6. When the second gear 6 rotates, it drives the first connecting shaft 4 to rotate. The rotation of the first connecting shaft 4 then drives the third gear 7 to rotate, which in turn drives the rack 3 to move. When the limiting part 9 is loaded with an object to be transported, the movement of the rack 3 achieves the function of transporting the object.

[0042] During the transportation of objects, if the rack 3 wobbles, the object may fall off the limiting part 9 or its position may change. Therefore, in this embodiment, if... Figure 4 As shown, the rack 3 is configured as several individual sub-chains 31, and the plate chain guide plate 8 is provided with guide grooves 81. The second connecting shaft 311 of the sub-chain 31 is inserted into the guide groove 81, so that the sub-chain 31 slides along the guide groove 81. Several sub-chains 31 are arranged in sequence so that each sub-chain 31 abuts against each other. During the transportation of objects, each sub-chain 31 slides along the guide groove 81, so that the rack 3 does not shake during the movement, thereby solving the problem of low material transportation efficiency caused by the loosening of the rack 3 in the plate chain conveyor.

[0043] Meanwhile, in order to facilitate the movement of the sub-chain 31 within the guide groove 81, bearings can be installed at both ends of the second connecting shaft 311. When the sub-chain 31 moves, the bearings rotate to reduce the friction between the second connecting shaft 311 and the guide groove 81.

[0044] In some embodiments, a support plate 10 is further included, which is disposed on both sides of the motor 2. The two ends of the first connecting shaft 4 pass through the support plate 10 and are connected to the chain guide plate 8. The support plate 10 is mainly used to support the first connecting shaft 4 and provide a support point for the first connecting shaft 4. In order to reduce the wear of the first connecting shaft 4 during rotation, a bearing can be provided at the connection between the support plate 10 and the first connecting shaft 4 to facilitate the rotation of the first connecting shaft 4.

[0045] In some embodiments, such as Figure 7As shown, it also includes a connecting piece 11, which has a connecting hole 111 and several first screw holes 112. The first connecting shaft 4 passes through the connecting hole 111 and connects to the connecting piece 11. The connecting piece 11 fits against the support plate 10, and the connecting piece 11 is connected to the support plate 10 through the first screw holes 112. The first screw holes 112 on the connecting piece 11 are for fixing the connecting piece 11 to the support plate 10 together using screws or other fasteners. The first screw holes 112 can be located at the edge of the connecting piece 11, and there can be multiple first screw holes 112 so that when the connecting piece 11 and the support plate 10 fit together, they can be securely locked together by screws.

[0046] At the same time, the connecting piece 11 and the supporting piece can fit together completely. This provides a larger contact area, thereby increasing the stability and load-bearing capacity of the connection.

[0047] In some embodiments, such as Figure 3 As shown, the sub-chain 31 also includes a connecting plate 312, which has several grooves 3121. Any two adjacent connecting plates 312 mesh with each other. By providing grooves 3121 in the connecting plate 312 and ensuring that any two adjacent connecting plates 312 mesh with each other, the third gear 7 can drive the sub-chain 31 to move when it rotates. At the same time, the two connecting plates 312 mesh with each other through the grooves 3121, and there is a certain gap between the two connecting plates 312. The gear of the third gear 7 can be inserted into the gap between the two connecting plates 312, thereby driving the sub-chain 31 to move by rotating the third gear 7.

[0048] In some embodiments, such as Figure 6 As shown, the limiting part 9 includes a claw 91 and a fixing part 92. The claw 91 and the fixing part 92 are detachably connected. The fixing part 92 is provided with a second screw hole at the end away from the claw 91. The fixing part 92 is connected to the connecting plate 312 through the second screw hole.

[0049] The jaw 91 is the part that directly contacts the object being transported, and its shape is adapted to the size and shape of the object. As a clamping element, the jaw 91 is used to directly fix or restrict the movement of the object.

[0050] The jaw 91 is detachably connected to the fixing part 92. For example, the fixing part 92 is provided with a threaded hole, and one end of the jaw 91 is provided with a bolt post. By aligning the bolt post with the threaded hole, the jaw 91 can be rotated to screw the bolt post into the fixing part 92. The detachable connection between the jaw 91 and the fixing part 92 not only facilitates maintenance and replacement, but also allows for the replacement of jaws 91 of different shapes or sizes according to different usage requirements, increasing the flexibility and applicability of the plate chain conveyor.

[0051] The fixing part 92 serves as a support structure for the claw 91. Its function is to stabilize the position of the claw 91 and bear the force transmission from the claw 91. The fixing part 92 and the claw 91 are connected by a detachable method, such as screw fixing or plug-in mating. This design allows the fixing part 92 to be quickly assembled or disassembled with the claw 91 as needed, improving the maintainability and adjustability of the limiting part 9.

[0052] The second screw hole on the fixing part 92 is for connecting the fixing part 92 to the connecting plate 312, and for adjusting the distance between the two fixing parts 92 according to the items to be transported.

[0053] In some embodiments, a collection rack 12 is also included, which is inserted into the end of the housing 1 away from the motor 2. Positioning the collection rack 12 away from the motor 2 provides operators with more operating space and a safer working environment. Moving parts such as the motor 2 and transmission system often pose a certain degree of danger; positioning the collection rack 12 away from these parts reduces the operator's chances of contact with the moving parts, thereby lowering safety risks. Because the collection rack 12 has an insert design, it can be easily disassembled and replaced. The insert design also makes routine maintenance and cleaning of the collection rack 12 simpler and faster. When the collection rack 12 needs cleaning or repair, workers can easily remove it from the housing 1 without requiring extensive disassembly of the entire device.

[0054] Furthermore, different production lines and production tasks may require collection racks 12 of different sizes and shapes. By setting the collection rack 12 at the end furthest from the motor 2, the collection rack 12 can be easily adjusted or replaced according to specific production needs. This allows the plate chain conveyor to adapt to various complex production environments and meet changing production requirements.

[0055] In some embodiments, a roller 13 is provided at the end of the housing 1 away from the plate chain guide plate 8. The roller 13 is a caster wheel. The roller 13 is provided at the bottom of the housing 1, and the caster wheel 13 is a caster wheel, which facilitates the movement of the plate chain transport device.

[0056] As can be seen from the above technical solution, this application provides a plate chain conveying device, including: a housing 1, a motor 2, a rack 3, a first connecting shaft 4, a first gear 5, a second gear 6, a third gear 7, a plate chain guide plate 8, and limiting parts 9; the plate chain guide plate 8 is symmetrically arranged on both sides of the housing 1; the rack 3 is sleeved on the plate chain guide plate 8; the output end of the motor 2 is connected to the first gear 5, and the first gear 5 meshes with the second gear 6; the second gear 6 is connected to the first connecting shaft 4, and both ends of the first connecting shaft 4 are respectively inserted into the plate chain guide plate 8, and both ends of the first connecting shaft 4 are respectively connected to the third gear 7, and the third gear 7 meshes with the rack 3; the plate chain guide plate 8 is provided with a guide groove 81 along its periphery, the rack 3 includes a plurality of sub-chains 31, each sub-chain 31 includes a second connecting shaft 311, and both ends of the second connecting shaft 311 are inserted into the guide groove 81 so that the sub-chains 31 are slidably connected to the plate chain guide plate 8; the rack 3 is provided with a plurality of limiting parts 9 at equal intervals. Sub-chain 31 is slidably connected to plate chain guide plate 8 via guide groove 81, so that each sub-chain 31 is in contact with plate chain guide plate 8. Pushing any one sub-chain 31 to move will cause the other sub-chains 31 to move in sequence, thus preventing the rack 3 from becoming loose and solving the problem of low material transportation efficiency caused by the loose rack 3 of the plate chain conveyor.
