It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] Reference Figures 1 to 8 As shown, the utility model provides a straightening mechanism for thin linear cross-belt sorting equipment, comprising: a driven shaft 1 and a supporting wheel disc 2.

[0027] The straightening mechanism for thin linear cross belt sorting equipment of the utility model is mainly used for thin linear cross belt sorting equipment. The specific structure of the thin linear cross belt sorting equipment is the prior art, and the specific structure is not repeated here. For details, please refer to the Chinese patent with publication number CN218144028U.

[0028] The utility model provides two sets of straightening mechanisms for thin linear cross-belt sorting equipment, which are respectively installed at the opposite ends of the thin linear cross-belt sorting equipment.

[0029] Specifically, the number of driven shafts 1 in each set of the straightening mechanism is two. Two driven shafts 1 are installed at each end of the support frame 3 of the thin linear cross-belt sorting device. The driven shaft 1 is arranged on the outside of the outer arc surface of the guide long rail 6 of the thin linear cross-belt sorting device. The two driven shafts 1 are arranged at the upper and lower ends of the outer arc surface of the guide long rail 6 in the arc direction. The driven shaft 1 is transmission-connected to the driving motor 7 of the thin linear cross-belt sorting device. The two driven shafts 1 rotate in the same direction. The rotation direction of the driven shaft 1 is opposite to the rotation direction of the sprocket 5 of the thin linear cross-belt sorting device.

[0030] The supporting wheel disc 2 is coaxially mounted on the driven shaft 1. A plurality of notches are formed on the outer edge of the supporting wheel disc 2. The plurality of notches are arranged at intervals along the circumferential direction of the supporting wheel disc 2. The supporting wheel discs 2 on the two driven shafts 1 are arranged in a staggered manner.

[0031] After one end of the front roller 41 of the non-flipping sorting trolley 4 (in this embodiment, the non-flipping sorting trolley can be a common sorting trolley) of the thin linear cross-belt sorting device slides to the top of the arc top of the guide long rail 6, a notch of the supporting wheel disc 2 above the guide long rail 6 is sleeved on the other end of the roller to limit the roller. The two supporting wheel discs 2 rotate synchronously to make the other end of the roller slide out of a notch at the arc top of the guide long rail 6, and at the same time, another notch of the supporting wheel disc 2 below the guide long rail 6 is sleeved on the other end of the roller at the arc top of the guide long rail 6 to continue to limit the roller. After the roller slides to the bottom of the arc top of the guide long rail 6, it disengages from the other notch.

[0032] Figure 4 The figure shows the state of the rollers of the non-flip sorting trolley (especially the rollers on the front side of the non-flip sorting trolley) before entering the slide groove of the guide long rail. Figure 5 It shows that when the roller of the non-flipping sorting trolley enters above the arc top of the slide groove of the long guide rail, a notch of the supporting wheel disc above the long guide rail just receives the state of being sleeved on the roller. Figure 6 What is shown is the state where the rollers of the non-tip sorting trolley reach the arc top of the slide groove of the guide long rail. At this time, a notch of the supporting wheel disc above the guide long rail and another notch of the supporting wheel disc below the guide long rail are aligned with the rollers of the non-tip sorting trolley, and the two supporting wheel discs complete the handover of the rollers at the arc top of the slide groove of the guide long rail. Figure 7 When the roller of the non-turnover sorting trolley reaches below the arc top of the slide groove of the guide long rail in another notch of the supporting wheel disc below the roller guide long rail, the roller is about to leave the other notch of the supporting wheel disc.

[0033] In this embodiment, the running track of a notch of the supporting wheel disc above the long guide rail coincides with a circular arc above the arc top of the chute of the long guide rail; the running track of another notch of the supporting wheel disc below the long guide rail coincides with a circular arc below the arc top of the chute of the long guide rail. The notches of the two supporting wheel discs intersect at the arc top of the chute of the long guide rail and complete the handover of the roller.

[0034] See also Figure 3 As shown, a driving motor 7 is installed at one end of the support frame. The driving motor drives the driving shaft 71 through a chain. The driving shaft drives the sprocket 5 to rotate through the chain, and at the same time, the driving shaft drives the driven shaft below the guide long rail through the chain. The driven shaft below the guide long rail is connected to the rotation of the driven shaft above the guide long rail through a transmission rack.

[0035] See also Figure 1 As shown, the two ends of the driven shaft 1 are respectively equipped with supporting wheel discs 2. The supporting wheel discs 2 are arranged on the side of the guide long rail 6 facing the non-turning sorting trolley 4.

[0036] In this embodiment, the roller 41 is rotatably connected to an axle. The axle is connected to the non-turning sorting trolley 4. The axle sleeve is provided with a shaft sleeve. After one end of the roller on the front side of the non-turning sorting trolley 4 of the thin straight cross belt sorting device slides to the top of the arc top of the guide long rail 6, a notch is sleeved on the shaft sleeve.

[0037] In this embodiment, the length of the notch gradually decreases from the outer edge of the supporting wheel disc 2 to the center of the supporting wheel disc 2 .

[0038] Continue reading Figure 3 As shown, the support frame 3 is installed with an assembly vertical plate 87. The long guide rail 6 is movably arranged on the inner side of the assembly vertical plate 87. Shock absorbers 8 are respectively installed between the upper and lower ends of the long guide rail 6 and the assembly vertical plate 87.

[0039] As a preferred implementation, the shock absorber 8 includes a base 81 , a first spring 83 , and a second spring 84 .

[0040] For details, see Figure 8 As shown, there are two bases 81 in each shock absorber. The two bases are arranged opposite to each other. The bases are installed on the inner side of the mounting vertical plate 87. The bases 81 are provided with through holes. The guide cross bars 82 are movably penetrated in the through holes of the two bases 81.

[0041] The middle part of the guide crossbar 82 and the two bases 81 are respectively connected with a first spring 83. In this embodiment, the guide crossbar is a variable diameter rod. The outer diameter of the middle part of the guide crossbar is greater than the outer diameter of the end of the guide crossbar. The end of the guide crossbar can be movably inserted into the through hole of the base. The first spring can be movably sleeved on the end of the guide crossbar. The two ends of the first spring are respectively pressed against the end surface of the support and the middle part of the guide crossbar.

[0042] The second spring 84 is connected to the sliding sleeve and the guide long rail 6. The second spring 84 is arranged vertically with the sliding sleeve.

[0043] In this embodiment, the long guide rail 6 is mounted on the inner lining plate 86. The inner lining plate 86 is attached to the inner side of the mounting vertical plate 87. The end of the inner lining plate 86 is connected with a guide vertical rod 85. The guide cross bar 82 is provided with a plug hole. The end of the guide vertical rod 85 can be movably inserted into the plug hole. The second spring 84 is connected between the inner lining plate 86 and the guide cross bar 82.

[0044] The outer diameter of one end of the guide vertical rod away from the inner lining plate is smaller than the dimension of the other end of the guide vertical rod close to the inner lining plate. The second spring is movably sleeved outside the other end of the guide vertical rod.

[0045] The upper and lower guide rails are respectively subjected to shock absorption treatment by shock absorbers, so as to improve the running stability of the non-flipping sorting trolley 4 and avoid damaging the components such as the axle of the roller.

[0046] The utility model discloses a straightening mechanism for thin linear cross-belt sorting equipment, which limits the upper roller entering the arc top of the guide long rail through the notches of two supporting wheel discs rotating in the same direction and synchronously, and connects at the arc top of the guide long rail, and then limits the lower roller sliding to the arc top of the guide long rail through the supporting tray below the guide long rail, and limits the upper and lower rollers sliding to the arc top of the guide long rail in turn through the two supporting wheel discs, so that the non-flipping sorting trolley sliding to or hovering at the arc top of the guide long rail is overturned or turned over, ensuring that the non-flipping sorting trolley will not turn over and runs smoothly.

[0047] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
