Description

Technical Field

[0001] This utility model relates to the field of logistics conveying equipment technology, specifically a flow bar with a deceleration connector. Background Technology

[0002] In the processing industry, raw materials or semi-finished products often need to be transported to the next workstation due to process changes. To save manpower, materials are often placed on slide rails equipped with multiple rollers for transport. Because they allow materials to move smoothly, they are collectively called flow rails.

[0003] According to a public notice (No. CN222820703U) regarding a corrosion-resistant flow strip, the aforementioned application improves the corrosion resistance of the rollers by setting a corrosion-resistant electroplating layer. The drain hole facilitates the drainage of liquids falling into the concave track, preventing liquids from corroding the flow strip and affecting its use. Through the setting of the cleaning component, the operator can push the slider, which drives the cleaning brush to move, thereby cleaning up the debris, dust, and liquids that have fallen into the concave track, preventing these debris from corroding the flow strip and affecting the rollers' rolling. It eliminates the need for disassembly and cleaning, improving work efficiency and enhancing the practicality of the corrosion-resistant flow strip.

[0004] However, in actual use, the flow rails of the above-mentioned equipment often experience damage due to the increasing speed of the goods. Therefore, in order to prevent the goods from falling off the flow rails and causing impact damage due to excessive speed, the flow rails often need to reduce their speed according to the actual situation when transporting heavier goods. In view of this, we propose a flow rail with a deceleration connector. Utility Model Content

[0015] Compared with the prior art, this utility model provides a flow bar with a deceleration connector, which has the following beneficial effects:

[0016] 1. The flow bar with a deceleration connector, through the deceleration mechanism, in conjunction with the linkage and meshing transmission of the first toothed plate, the first rotating gear, the double-sided toothed plate, the second rotating gear and the second toothed plate, efficiently converts the vertical displacement of the guide wheel connecting seat into the lateral reciprocating motion of the second toothed plate and the connecting plate. When the guide wheel descends due to carrying an item, the mechanism can precisely drive the deceleration plate at the end of the connecting plate to be inserted laterally into the friction groove on the side wall of the guide wheel, thereby achieving an instantaneous, controllable and uniform deceleration effect on the rotation of the guide wheel.

[0017] 2. The flow bar with deceleration connector, through the setting of deceleration mechanism, together with the auxiliary mechanism below the first tooth plate, significantly improves the responsiveness and durability of the system. The telescopic spring is sleeved on the outside of the telescopic rod, providing a continuous upward reset elastic force for the first tooth plate. When the guide wheel carries the item and presses down, this elastic force provides a buffer; when the item is removed and the guide wheel is lifted and reset, the spring force can quickly and reliably pull the first tooth plate and the entire deceleration mechanism connected to it back to the initial position, thereby causing the deceleration plate to completely disengage from the friction groove of the guide wheel.

[0023] like Figures 1-4As shown, this utility model provides a technical solution: a flow bar with a deceleration connector, including a main frame 1, a fixed seat 11 fixedly connected to the lower surface of the main frame 1, a guide wheel 2 abutting against the side wall of the main frame 1, an outer wall of a bearing 21 fixedly connected to the inner wall of the guide wheel 2, a connecting shaft 22 fixedly connected to the inner wall of the bearing 21, a friction groove 23 formed on the inner surface of the guide wheel 2, a connecting seat 24 fixedly connected to the end of the connecting shaft 22 away from the guide wheel 2, and a deceleration mechanism 3 provided on the lower surface of the connecting seat 24. The deceleration mechanism 3 includes: a first toothed plate 31, a first rotating gear 32, a fixed shaft 33, a bidirectional toothed plate 34, a second rotating gear 35, a second toothed plate 36, a connecting plate 37, a deceleration plate 38, and a sliding groove 39.

[0024] In one embodiment of this utility model, the lower surface of the first toothed plate 31 is fixedly connected to the lower surface of the connecting seat 24. The tooth ends of the first toothed plate 31 mesh with the outer surface of the first rotating gear 32. A fixed shaft 33 is rotatably connected through the center of the first rotating gear 32. When the guide wheel 2 causes the connecting seat 24 to descend due to the weight, it will synchronously drive the first toothed plate 31 to move vertically, thereby enabling the first rotating gear 32 to start rotating. The outer surface of the first rotating gear 32 meshes with a bidirectional toothed plate 34. The end of the bidirectional toothed plate 34 away from the first toothed plate 31 is fixedly connected to the outer surface of the second rotating gear 35. The outer surface of the first rotating gear 32 meshes with one end of the bidirectional toothed plate 34. At this time, the bidirectional toothed plate 34 will move vertically at the same time.

[0025] Furthermore, the outer surface of the second rotating gear 35 meshes with the other end of the bidirectional gear plate 34, enabling the second rotating gear 35 to rotate. A fixed shaft 33 is rotatably connected through the center of the second rotating gear 35. The lower surface of the second gear plate 36 meshes with the outer surface of the second rotating gear 35. As the second rotating gear 35 rotates, it simultaneously pushes the second gear plate 36 to move. A connecting plate 37 is fixedly connected to one end of the second gear plate 36 near the guide wheel 2. A speed reducer 38 is detachably connected to one end of the connecting plate 37 near the guide wheel 2. The connecting plate 37 pushes the speed reducer 38 to rub against the friction groove 23 for deceleration. A sliding groove 39 is provided on the side wall of the main frame 1 near the guide wheel 2, allowing the connecting seat 24 sufficient movement space. A slot matching the size of the connecting plate 37 is provided on the side wall of the main frame 1 near the guide wheel 2. The size of the speed reducer 38 matches the size of the friction groove 23. Through the slot, the speed reducer 38 can have a larger... The friction area is large, resulting in better deceleration. The movable dimensions of the first toothed plate 31 and the second toothed plate 36 are matched, so that the movement of the guide wheel 2 matches the movement of the decelerator 38, resulting in better synchronization. The side wall of the bidirectional toothed plate 34 is slidably connected to a limit rod, which can limit the position of the bidirectional toothed plate 34 and prevent it from shifting. There are two sets of fixed shafts 33. The main frame 1 is provided with an installation groove, and the deceleration mechanism 3 is located inside the main frame 1. The ends of the fixed shafts 33 are fixedly connected to the two ends of the installation groove. The fixed shafts 33 can provide position support for the first rotating gear 32 and the second rotating gear 35. The end of the second toothed plate 36 away from the guide wheel 2 is provided with a limit groove, and the end of the installation groove near the limit groove is fixedly connected to a limit post. The limit post and the limit groove can limit the relative position of the second toothed plate 36 and prevent it from shifting.

[0026] In addition, an auxiliary mechanism 4 is provided on the lower surface of the first toothed plate 31. The auxiliary mechanism 4 includes a telescopic rod 41. The ends of the telescopic rod 41 are fixedly connected to the bottom surface of the mounting groove and the bottom surface of the first toothed plate 31, respectively. A telescopic spring 42 is sleeved on the outer surface of the telescopic rod 41. One end of a protective sleeve 43 is fixedly connected to the bottom surface of the mounting groove. The other end of the protective sleeve 43 is fixedly connected to the lower surface of the first toothed plate 31. When the guide wheel 2 bears a heavy object, the telescopic rod 41 and the telescopic spring 42 will provide reactive support. After the object is moved away, the telescopic spring 42 and the telescopic rod 41 will support the first toothed plate 31 to rebound, further promoting the guide wheel 2 to reset, so as to eliminate the deceleration effect caused by the deceleration mechanism 3 in time.

[0027] In this embodiment of the invention, the outer surface of the friction groove 23 is provided with grooves, which are distributed in a circumferential array on the outer surface of the friction groove 23. These grooves enable the friction groove 23 to have a better deceleration effect. Furthermore, when the deceleration plate 38 is rubbing, air can be embedded into the interior of the deceleration plate 38 and the friction groove 23 through the grooves, creating a cooling effect on the friction groove 23 and the deceleration plate 38. The shapes of the connecting plate 37 and the deceleration plate 38 match the shape of the friction groove 23. This matching of the shapes of the connecting plate 37, the deceleration plate 38, and the friction groove 23 allows the deceleration plate 38 to better conform to the surface of the friction groove 23, improving the friction effect. The deceleration mechanism 3... The guide wheel 2 is equipped with multiple sets of deceleration mechanisms 3, with each pair of deceleration mechanisms 3 distributed symmetrically on both sides of the guide wheel 2 in a mirror image. The multiple sets of deceleration mechanisms 3 ensure that each set of guide wheels 2 has a deceleration effect, which can better guarantee the effect of transporting heavy objects. The main frame 1 and the fixed seat 11 are set in a U-shape. The size of the guide wheel 2 matches the size of the recess formed by the main frame 1 and the fixed seat 11. A rubber ring is fixedly connected to the outer surface of the guide wheel 2. The U-shaped main frame 1 and the fixed seat 11 can make the guide wheel 2 have a better rotation effect. By fixing the rubber ring to the outer surface of the guide wheel 2, damage to the transported items can be prevented while increasing the friction between the guide wheel 2 and the transported items.

[0028] In this invention, when the weight of an object presses on the guide wheel 2, the guide wheel 2 drives the connecting seat 24 below to move downwards via the connecting shaft 22. The connecting seat 24 drives the first toothed plate 31 fixed to it to move downwards. The first toothed plate 31 meshes with and drives the first rotating gear 32 to rotate. The first rotating gear 32 then drives the bidirectional toothed plate 34 meshing with it to move. The bidirectional toothed plate 34 then drives the second rotating gear 35 to rotate. The second rotating gear 35 meshes with and pushes the second toothed plate 36 to move horizontally. The second toothed plate 36 drives the deceleration plate 38 at its end to be pushed horizontally into the friction groove 23 opened on the side wall of the guide wheel 2 via the connecting plate 37. The friction generates resistance, thereby realizing the deceleration and braking of the guide wheel 2. When the weight of the object is reduced or removed, the auxiliary mechanism 4 helps the first toothed plate 31 to reset, driving the entire mechanism to move in the opposite direction, so that the deceleration plate 38 disengages from the friction groove 23, and the guide wheel 2 resumes free rotation.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
