Description

Technical Field

[0001] This application relates to the field of transportation technology, and more specifically, to a positioning device, transportation system, and filling machine equipment for dual-chain push. Background Technology

[0002] In related fields, chains are widely used due to their high efficiency and high load capacity. In situations where precise positioning is required, positioning accessories or pallets need to be installed on the chains to achieve stable material transport.

[0003] When transporting material buckets, a lever is typically added to the chain to move the bucket. The chain drives the lever, allowing it to stably push the bucket within a limited space. The lever is usually connected to the chain using a hollow pin, secured with rivets. However, when pushing an object, the shoulder of the lever-chain connection experiences repeated tangential forces, making the hollow pin prone to fatigue fracture. Furthermore, the four rivets securing the lever and chain prevent quick disassembly and maintenance. Replacing the lever with a new one can easily cause the pin to expand, resulting in an overly tight fit between the pin and chain, preventing proper rotation and causing transmission failure.

[0004] Therefore, how to improve the stability of material pushing by dual chains has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a positioning device for dual-chain pushing, so as to improve the stability of dual-chain pushing of materials.

[0006] Another objective of this application is to provide a transportation system having the aforementioned positioning device.

[0007] Another objective of this application is to provide a filling machine device having the above-mentioned transportation system.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] A positioning device for dual-chain pushing, comprising:

[0010] A lever assembly, comprising a lever and a connecting shaft, wherein the connecting shaft is rotatably mounted on the lever, and there are multiple connecting shafts, one of which is movable on the lever along the transmission direction of the chain;

[0011] A connector is provided for fixing to the chain, and both ends of the connecting shaft are respectively used for detachable connection to the connectors on two parallel chains, so that the lever is located between the two chains.

[0012] Optionally, in the above positioning device, the connector includes a first connecting portion and a second connecting portion disposed perpendicular to the first connecting portion. The first connecting portion of the connector is used to connect with the chain. The end of the connecting shaft is provided with a slot that mates with the second connecting portion of the connector. The second connecting portion of the connector is inserted into the slot and fixed by fasteners.

[0013] Optionally, in the above positioning device, the slot extends from the end face of one end of the connecting shaft toward the other end of the connecting shaft.

[0014] Optionally, in the above positioning device, two mounting notches extending toward the slot are symmetrically arranged on the outer peripheral surface of the end of the connecting shaft, and a first mounting hole that can penetrate into the slot is provided at the position of the two mounting notches. The second connecting part of the connector is provided with a second mounting hole that mates with the first mounting hole, and the fastener is respectively inserted into the first mounting hole and the second mounting hole.

[0015] Optionally, in the above positioning device, the mounting notch has a contact surface that abuts against the fastener, and the contact surface is a plane.

[0016] Optionally, in the above positioning device, the first connecting part of the connector is a gourd-shaped structure adapted to the chain, and the first connecting part of the connector is fixedly connected to the chain by rivets.

[0017] Optionally, in the above positioning device, the lever includes a push-block part for pushing materials and a movable part arranged perpendicular to the push-block part. The movable part is respectively provided with a fixing hole for mounting the connecting shaft and a waist-shaped hole for the connecting shaft to move along the transmission direction of the chain.

[0018] Optionally, in the above positioning device, a limiting snap ring is provided at the connection position between the connecting shaft and the lever to restrict the axial movement of the connecting shaft.

[0019] A transportation system includes two parallel chains and a positioning device for pushing the two chains as described in any of the preceding claims, wherein multiple positioning devices are spaced apart along the transmission direction of the chains.

[0020] A filling machine includes a transport system as described above.

[0021] The positioning device for dual-chain pushing provided in this application rotatably mounts multiple connecting shafts on a lever, one of which can move along the chain's transmission direction to compensate for displacement changes when passing through the sprocket. Simultaneously, both ends of the connecting shaft are detachably connected to connectors on two chains, thereby enabling the chain to drive the lever assembly to move, allowing the lever assembly's lever to push material transport. As can be seen from the above example, the positioning device for dual-chain pushing provided in this application, with the connecting shaft rotatably connected to the lever, reduces the tangential force at the shoulder where the lever connects to the chain, lowering the risk of breakage at the shoulder. Furthermore, the lever assembly can be quickly replaced by disassembling the connection between the connecting shaft and the connector, improving the stability of dual-chain material pushing.

[0032] The core of this application is to provide a positioning device for dual-chain pushing, so as to improve the stability of dual-chain pushing of materials.

[0033] Another core aspect of this application is to provide a transportation system having the aforementioned positioning device.

[0034] Another core aspect of this application is to provide a filling machine with the aforementioned transportation system.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] In related fields, chains are widely used due to their high efficiency and high load capacity. In situations where precise positioning is required, positioning accessories or pallets need to be installed on the chains to achieve stable material transport.

[0037] In the filling machine system, the material barrels are transported on the production line by a chain motor system, so that the material barrels can accurately stop at the filling station, capping station and weighing station, thereby ensuring the realization of each process on the production line.

[0038] When transporting material buckets, a lever is typically added to the chain to move the bucket. The chain drives the lever, allowing it to stably push the bucket within a limited space. The lever is usually connected to the chain using a hollow pin, secured with rivets. However, when pushing an object, the shoulder of the lever-chain connection experiences repeated tangential forces, making the hollow pin prone to fatigue fracture. Furthermore, the four rivets securing the lever and chain prevent quick disassembly and maintenance. Replacing the lever with a new one can easily cause the pin to expand, resulting in an overly tight fit between the pin and chain, preventing proper rotation and causing transmission failure.

[0039] Therefore, such as Figure 1 As shown in the figure, this application discloses a positioning device for dual-chain pushing, including a lever assembly 10 and a connector 20. The lever assembly 10 is rotatably connected to the lever 11 via a connecting shaft 12, which reduces the tangential force at the shoulder where the lever 11 connects to the chain 30, thus reducing the risk of breakage at the shoulder. Furthermore, the lever assembly 10 can be quickly replaced by disassembling the connection between the connecting shaft 12 and the connector 20, improving the stability of the dual-chain pushing of materials.

[0040] The following will combine Figures 1 to 5 The positioning device for dual-chain push disclosed in the embodiments of this application will be explained and described in detail.

[0041] Among them, such as Figure 1 As shown, the lever assembly 10 may include a lever 11 and a connecting shaft 12. Multiple connecting shafts 12 may be used, for example, two connecting shafts 12. Each connecting shaft 12 is rotatably mounted on the lever 11 to reduce the tangential force at the shoulder where the lever 11 connects to the chain 30, thus reducing the risk of breakage at the shoulder. Simultaneously, one of the connecting shafts 12 can move along the transmission direction of the chain 30 on the lever 11 to compensate for displacement changes when the lever assembly 10 passes through the sprocket. Furthermore, as... Figure 2 As shown, the connector 20 can be fixed to the chain 30, and both ends of the connecting shaft 12 are detachably connected to the connectors 20 on the two parallel chains 30, respectively, enabling quick replacement of the lever assembly 10 and allowing the lever 11 to be positioned between the two chains 30, as shown. Figure 3 As shown, this enables the chain 30 to drive the lever assembly 10 to move, so that the lever 11 of the lever assembly 10 can push the material transport, thereby improving the stability of the double chain 30 pushing the material.

[0042] In some embodiments, such as Figure 2 As shown, the connector 20 can adopt an approximately L-shaped structure, and the connector 20 may include a first connecting portion 21 and a second connecting portion 22 disposed perpendicular to the first connecting portion 21. The first connecting portion 21 of the connector 20 can be connected to the chain 30, and simultaneously... Figure 1 As shown, a slot 121 is provided at the end of the connecting shaft 12 to mate with the second connecting portion 22 of the connector 20, so that the second connecting portion 22 of the connector 20 can be inserted into the slot 121 and fixed by fasteners 13 such as fixing pins, thereby realizing quick assembly and disassembly between the lever assembly 10 and the chain 30. Figure 3 and Figure 4 As shown. It should be noted that fastener 13 can also be used with bolts and nuts to achieve quick assembly and disassembly between the lever assembly 10 and the chain 30, which is not limited here.

[0043] In some embodiments, such as Figure 1 As shown, the slot 121 can extend from the end face of one end of the connecting shaft 12 toward the other end of the connecting shaft 12, and the slot 121 can be radially through the end face of one end of the connecting shaft 12, so that the second connecting part 22 of the connector 20 can be inserted into the slot 121.

[0044] In some embodiments, such as Figure 1 and Figure 4 As shown, two mounting notches 122 extending toward the slot 121 are provided on the outer peripheral surface of the end of the connecting shaft 12, and the two mounting notches 122 are symmetrically arranged about the slot 121. At the same time, a first mounting hole 1221 that can pass through the slot 121 is opened at the position of the two mounting notches 122, and as shown... Figure 2 As shown, the second connecting part 22 of the connector 20 may have a second mounting hole 221 that mates with the first mounting hole 1221, so that the fastener 13 can be inserted into the first mounting hole 1221 and the second mounting hole 221 to achieve the connection and fixation between the lever assembly 10 and the chain 30.

[0045] In some embodiments, such as Figure 1 and Figure 4 As shown, the mounting notch 122 has a contact surface 1222 that abuts against the fastener 13, and the contact surface 1222 is flat to ensure the reliability of the fastener 13 connecting the lever assembly 10 and the chain 30.

[0046] In the above embodiments, fasteners 13 such as fixing pins with different diameters and strengths can be set for different loads to enhance the strength of the lever assembly 10. If a fixing pin or other fastener 13 breaks, it can be replaced individually, saving on later maintenance costs. At the same time, the breakage of a single fixing pin or other fastener 13 will not cause the entire chain to break, thereby avoiding the risk of escalation in equipment operation.

[0047] In some embodiments, such as Figure 2 As shown, the first connecting part 21 of the connector 20 can adopt a gourd-shaped structure adapted to the chain 30, and the first connecting part 21 of the connector 20 can be fixedly connected to the inner side of the chain 30, that is, the opposite side of the two chains 30, by rivets, so as to ensure that the chain 30 passes smoothly through the sprocket and avoid interference from the first connecting part 21 of the connector 20.

[0048] In some embodiments, such as Figure 1As shown, the lever 11 can be composed of a push-block part 111 capable of pushing materials and a movable part 112 arranged perpendicularly to the push-block part 111. The movable part 112 is provided with a fixing hole 1121 and a slotted hole 1122, and one of the connecting shafts 12 can pass through the fixing hole 1121 and rotate within it. Axial limiting is achieved by a limiting spring 14 to prevent the connecting shaft 12 from dislodging from the fixing hole 1121. Figure 5 As shown, another connecting shaft 12 can pass through the waist-shaped hole 1122 and move along the transmission direction of the chain 30 to compensate for the displacement change of the lever assembly 10 when passing through the sprocket. At the same time, it can rotate within the waist-shaped hole 1122 and can be axially limited by the limiting snap ring 14 to prevent the connecting shaft 12 from coming out of the waist-shaped hole 1122.

[0049] The positioning device for dual-chain pushing disclosed in this application embodiment has multiple connecting shafts 12 rotatably arranged on the lever 11, and one of the connecting shafts 12 can move along the transmission direction of the chain 30 on the lever 11 to compensate for the displacement change when passing through the sprocket. At the same time, the two ends of the connecting shaft 12 are detachably connected to the connecting parts 20 on the two chains 30 respectively, so that the chain 30 drives the lever assembly 10 to move, so that the lever 11 of the lever assembly 10 can push the material transport.

[0050] The positioning device for pushing the double chain 30 disclosed in this application embodiment is rotatably connected to the lever 11 via the connecting shaft 12. This reduces the tangential force at the shoulder where the lever 11 connects to the chain 30, thereby reducing the risk of breakage at the shoulder where the lever 11 connects to the chain 30. At the same time, the lever assembly 10 can be quickly disassembled and assembled by disassembling the connection between the connecting shaft 12 and the connector 20, thus improving the stability of the double chain 30 pushing materials.

[0051] This application also discloses a transportation system, including two parallel chains 30 and a positioning device for dual-chain pushing as disclosed in the above embodiment. Therefore, this transportation system possesses all the technical effects of the aforementioned positioning device, which will not be repeated here. Multiple positioning devices can be spaced apart along the transmission direction of the chains 30 to simultaneously push multiple materials, thereby improving the transportation efficiency of the system.

[0052] This application also discloses a filling machine, which includes the transportation system disclosed in the above embodiments. Therefore, the filling machine has all the technical effects of the above transportation system, and will not be described again here.

[0053] The terms "first" and "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.
