Description

Technical Field

[0001] This utility model relates to the field of transportation machinery technology, and in particular to an anti-wear positioning device and a train alignment arm. Background Technology

[0002] In the automation of beverage production and packaging, beverage cartons are typically transported onto conveyor belts in a stacked or scattered manner. Due to the high conveying speed, uneven friction, or slight differences in the shape of the cartons, the stacks of beverage cartons are prone to skewing, misalignment, or uneven stacking during transport. This not only affects the accuracy of subsequent processes such as boxing, palletizing, or inspection, but may also cause jamming, collisions, or even machine shutdowns, thereby reducing production efficiency and increasing maintenance costs. To solve these problems, production lines are usually equipped with a aligning mechanism. The aligning arm guides and pushes the stacks of beverage cartons, rearranging the scattered stacks into a neat queue, ensuring that the materials remain stable and orderly during high-speed transport.

[0003] Traditional alignment arms are driven by chains. However, chain drives require a positioning device to rotate the alignment arms so that they fit the chain and reduce the space they occupy. However, the positioning device will cause friction when it comes into contact with the alignment arms. If the friction time is too long, the entire positioning device needs to be replaced, which can easily lead to waste. Utility Model Content

[0021] In traditional beverage carton alignment systems, the contact surface between the positioning device and the alignment arm experiences structural wear due to long-term friction, leading to gradual material loss in the positioning groove area. When the wear depth exceeds the allowable tolerance, the positioning device can no longer effectively constrain the rotation trajectory of the alignment arm. If this problem is not addressed, the structural wear of the positioning device will trigger a chain reaction of transmission system failures. Please refer to [reference needed]. Figures 1-3 This utility model provides a wear-resistant positioning device, including: a positioning arm 100, on one side of which a first connecting hole 110 and a second connecting hole 120 are provided along its length; a wear-resistant component 200 is detachably disposed on the positioning arm 100 via a detachable connector and located between the first connecting hole 110 and the second connecting hole 120. Further, the positioning arm 100 refers to a long strip-shaped structural component used to support and install other components, specifically made of metal or high-strength engineering plastic, serving to support the wear-resistant component 200 and transmit mechanical force. The first connecting hole 110 refers to the first fixing hole opened along the length of the positioning arm 100, specifically using a circular or elliptical hole structure, used for connection and positioning with external components. The second connecting hole 120 refers to the second fixing hole opened along the length of the positioning arm 100. The wear-resistant component 200 refers to a functional component used to reduce frictional wear, specifically made of high-hardness alloy, ceramic material, or wear-resistant nylon, and its detachable design allows for individual replacement after wear, avoiding the scrapping of the entire structure. A detachable connector refers to a mechanical structure that enables a non-fixed connection between the wear-resistant part 200 and the positioning arm 100. Specifically, it can be implemented using bolts, which facilitates quick disassembly and maintenance.

[0022] This application uses modular design of the detachable wear-resistant part 200 to separate the easily worn parts from the main body of the positioning arm 100, which significantly reduces maintenance costs while ensuring the positioning function and avoids the waste of resources caused by replacing the whole due to local wear in traditional solutions.

[0023] In this embodiment, the detachable connector includes a positioning groove on one side of the positioning arm 100. A countersunk through hole (not shown in the figure) is provided at the bottom of the positioning groove, penetrating the side of the positioning arm 100 away from the positioning groove. A threaded hole (not shown in the figure) is provided on the side of the wear-resistant component 200 facing the positioning groove (not shown in the figure). Furthermore, the positioning groove is formed on the surface of the positioning arm 100 that contacts the wear-resistant component 200, serving to accommodate part of the structure of the wear-resistant component 200. The countersunk through hole is located at the center of the bottom of the positioning groove, and its diameter is larger than the bolt head diameter, so that the bolt head, after being inserted, is flush with the bottom surface of the positioning groove and extends from the bottom of the positioning groove to the other side of the positioning arm 100, forming a through channel. Specifically, the positioning groove provides an installation reference surface for the wear-resistant part 200. Through the engagement of the countersunk through-hole and the connecting through-hole, the bolt passes through the positioning arm 100 and screws into the threaded hole of the wear-resistant part 200. The countersunk through-hole design ensures the bolt head is fully embedded in the positioning groove, preventing exposed structures from interfering with adjacent components. The threaded hole and the bolt end form a threaded engagement, and tightening the bolt secures the wear-resistant part 200 within the positioning groove. Disassembly only requires loosening the bolt to separate the wear-resistant part 200 without damaging the positioning arm 100 structure.

[0024] In this embodiment, the alignment arm includes an anti-wear positioning device and a first alignment rod body 300. One end of the first alignment rod body 300 is provided with a mounting plate 310, one end of which is detachably connected to the first alignment rod body 300, and the other end of which is connected to the positioning arm 100. Furthermore, the mounting plate 310 adopts a split structure; one end is detachably connected to the first alignment rod body 300 via bolts or clips, and the other end is fixed to the surface of the positioning arm 100. Positioning holes are provided on both sides of the mounting plate 310, and the end of the first alignment rod body 300 is machined with a protrusion structure matching the positioning holes, enabling rapid positioning via pin insertion.

[0025] In this embodiment, the mounting plate 310 is provided with a connecting post 311 connected to the first connecting hole 110 and an eighth connecting hole 450 adapted to the countersunk through hole. Further, the axis of the connecting post 311 coincides with the axis of the first connecting hole 110, and the diameter of the connecting post 311 forms a clearance fit or an interference fit with the inner diameter of the first connecting hole 110. In some embodiments, the end of the connecting post 311 may be provided with an external thread structure to form a threaded fastening connection with the internal thread of the first connecting hole 110.

[0026] In this embodiment, a connecting cylinder 400 is included, along with a connecting sleeve 410 sleeved on the end of the connecting cylinder 400 away from the mounting plate 310. The connecting sleeve 410 has a third connecting hole 420, the connecting cylinder 400 has a fourth connecting hole 430, the mounting plate 310 has a fifth connecting hole 312, and the alignment rod has a sixth connecting hole (not shown in the figure) corresponding to the third connecting hole 420. The third connecting hole, fourth connecting hole 430, fifth connecting hole 312, and sixth connecting hole combine to form a connecting channel. Furthermore, the third connecting hole 420 and the fourth connecting hole 430 respectively penetrate the sidewalls of the connecting sleeve 410 and the connecting cylinder 400, the fifth connecting hole 312 is located on the side of the mounting plate 310 near the connecting cylinder 400, and the sixth connecting hole is located at the end of the alignment rod that contacts the connecting sleeve 410. The central axes of the third connecting hole 420, the fourth connecting hole 430, the fifth connecting hole 312, and the sixth connecting hole coincide, forming a continuous channel that passes through the connecting sleeve 410, the connecting cylinder 400, the mounting plate 310, and the entire row of rods. Bolts or pins can be inserted into the connecting channel to achieve a rigid connection between multiple components through threaded fastening or interference fit.

[0027] In this embodiment, a first drive chain 500 and a second drive chain 510 disposed beside the first drive chain 500 are included. The alignment rod is mounted on the first drive chain 500 via a rotating assembly 600. Further, the rotating assembly 600 includes a pin 610 and a sleeve 620 fitted outside the pin 610. The sleeve 620 is fixedly connected to a link of the first drive chain 500, and the end of the pin 610 is rotatably connected to the mounting plate 310 of the alignment rod.

[0028] Specifically, the alignment rod rotates around the axis of the first transmission chain 500 through the cooperation of the shaft pin 610 and the bushing 620. When the chain moves, the alignment rod can automatically adjust its angle according to the transmission path to avoid rigid collision with the beverage box stack.

[0029] In this embodiment, the assembly component 600 includes a pin 610 and a sleeve 620 fitted outside the pin 610. The sleeve 620 is disposed within the second connecting hole 120. The other end of the pin 610 is rotatably connected to a U-shaped block 630. The top of the U-shaped block 630 is provided with a seventh connecting hole 640. The U-shaped block 630 is connected to the first transmission chain 500 through the cooperation of the seventh connecting hole and the connecting member. Furthermore, the cooperation structure between the pin 610 and the sleeve 620 forms a rotating pair. The sleeve 620 is embedded in the second connecting hole 120 of the positioning arm 100, and the U-shaped block 630 is fixed to the chain link through the seventh connecting hole 640. The rotatable connection between the end of the pin 610 and the U-block 630 allows the entire arm to rotate around the axis of the pin 610. The bushing 620 is made of wear-resistant material. Bolts or pins are inserted into the seventh connecting hole 640. The U-block 630 is aligned with the mounting hole of the chain and then tightened.

[0030] In this embodiment, a second alignment rod 700 is included, which is disposed on the second drive chain 510. The second alignment rod 700 is used to maintain the distance between the beverage carton stacks. Further, the second alignment rod 700 is assembled to the second drive chain 510 via a U-shaped block 630. The second drive chain 510 and the first drive chain 500 are parallel and driven by independent gear sets. A phase difference is formed between the second alignment rod 700 and the first alignment rod body 300 during transmission.

[0031] In this embodiment, the first transmission chain 500 is driven by the first gear set 520, and the second transmission chain 510 is driven by the second gear set 530. Furthermore, the second alignment rod 700 moves synchronously with the transmission direction of the second transmission chain 510, and the end of the second alignment rod 700 is provided with a guide surface that contacts the side of the beverage carton stack.

[0032] In this embodiment, the first transmission chain is provided with an L-shaped positioning block 540 that acts on the wear-resistant component 200 to cause the first row of rods body 300 to rotate. Further, the L-shaped positioning block 540 is fixed at a specific position on the chain, and its shape is designed to have a vertical section and a horizontal section, with the horizontal section extending in the same direction as the chain's movement. The wear-resistant component 200 is connected to the positioning arm 100 through a threaded hole and is located between the positioning groove and the countersunk through hole. When the vertical section of the L-shaped positioning block 540 contacts the wear-resistant component 200, the chain movement pushes the wear-resistant component 200 to move, thereby causing the row of rods to rotate around the pivot pin 610.
