[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 and 2 As shown, a narrow-band sorting trolley based on a profile body includes a trolley body 1, a belt conveyor mechanism 2, a tensioning and locking assembly 3, and two supporting link assemblies 4 respectively installed at both ends of the trolley body 1. The trolley body 1 is made of aluminum alloy profile. The length direction of the trolley body 1 is parallel to the extrusion direction of the aluminum alloy profile; using aluminum alloy profile as the trolley body 1 helps to simplify the structural complexity of the narrow-band sorting trolley and can improve the overall structural strength of the narrow-band sorting trolley with a smaller width. At the same time, the weight of the aluminum profile is reduced, which helps to improve the stability of the sorting machine operation and reduce energy consumption.

[0026] The top surface of the trolley body 1 is provided with a plurality of limiting grooves 1-1 extending along the length direction of the trolley body 1. The limiting grooves 1-1 are arranged in sequence at equal intervals along the width direction of the trolley body 1. The front and rear sides of the trolley body 1 are both provided with T-shaped grooves 1-2 with a larger inner side and a smaller outer side. The limiting grooves 1-1 and the T-shaped grooves 1-2 are both directly obtained during the extrusion molding of the aluminum alloy profile.

[0027] like Figure 3 As shown, the supporting link assembly 4 includes a roller side plate 4-1, a supporting guide plate 4-2, a link frame 4-3, a wheel axle, a walking roller 4-4 and a link bearing 4-6. The two roller side plates 4-1 are respectively arranged on the front and rear sides of the end of the trolley body 1. The through holes on the roller side plates 4-1 are fixed to the T-slots 1-2 on the side of the trolley body 1 by bolts and nuts. Since the nut can adjust the position in the T-slot 1-2, the connection position between the supporting link assembly 4 and the trolley body 1 is flexible and adjustable, which reduces the processing accuracy requirements of the trolley body 1.

[0028] The bottom of the roller side plate 4-1 is provided with a connection structure protruding inward. The two ends of the inner side surface of the support guide plate 4-2 are fixed to the connection structure at the bottom of the two roller side plates 4-1 by bolts respectively. The support guide plate 4-2 is parallel to the travel direction of the narrow-band sorting trolley.

[0029] The support guide plate 4-2 is provided with a horizontal mounting plate formed by bending a sheet metal. The horizontal mounting plate is rotatably connected to a guide roller 4-5 with a vertical axis. The wheel axle is fixed to the bottom of the support guide plate 4-2 and penetrates the support guide plate 4-2. The walking roller 4-4 is rotatably connected to the wheel axle and is located outside the support guide plate 4-2.

[0030] The link frame 4-3 is fixed to the inner side of the support guide plate 4-2 by bolts. The link bearing 4-6 is fixed to the end of the link frame 4-3. The link bearing 4-6 and the wheel axle are respectively arranged at the two ends of the support link assembly 4. Specifically, the link bearing 4-6 is connected to the link frame 4-3 through a connecting column and a bearing seat. The connecting column is in the shape of an arched column (i.e., the cross section is arched). The cross-sectional profile shape of the connecting column matches the cross-sectional profile shape of the mounting groove provided at the end of the link frame 4-3, so that the mounting groove can provide circumferential positioning for the connecting column. The bearing seat and the end of the connecting column are integrally formed. The link bearing 4-6 is installed in the bearing seat and is axially positioned by a retaining spring. In this embodiment, the link bearing 4-6 adopts a rotating bearing.

[0031] In the narrow-band sorting machine using the utility model, the inner ring of the link bearing 4-6 in the front narrow-band sorting trolley is sleeved on the axle in the rear narrow-band sorting trolley to realize the link between two adjacent narrow-band sorting trolleys.

[0032] The belt conveyor mechanism 2 includes a conveying roller and a conveyor belt 2-3. The two conveying rollers are respectively installed on two supporting link assemblies 4. Specifically, the two ends of the conveying roller are respectively connected to the two roller side plates 4-1 in the corresponding supporting link assembly 4. The two rollers are respectively the active roller 2-1 and the driven roller 2-2. The active roller 2-1 and the driven roller 2-2 are connected by transmission through the conveyor belt 2-3. The active roller 2-1 adopts an electric roller. The inner side surface of the conveyor belt 2-3 is provided with a plurality of limiting ribs extending along its own length direction. The limiting ribs on the inner side surface of the conveyor belt 2-3 are equal in number and correspond one to one to the limiting grooves 1-1 on the top surface of the trolley body 1. Each limiting rib extends into the corresponding limiting groove 1-1, so that the limiting groove 1-1 can prevent the conveyor belt 2-3 from deflecting during the conveying process.

[0033] like Figure 4 As shown, the conveying roller includes a roller shaft 2-4 and a cylinder body. The cylinder body is coaxially connected to the roller shaft 2-4; two tensioning and locking components 3 are respectively installed on two roller side plates 4-1 of one of the supporting link components 4, and are used to tension and lock the roller shaft 2-4 installed on the conveying roller on the supporting link component 4. The tensioning and locking component 3 includes a tensioning bolt 3-1 and a locking bolt 3-2.

[0034] In the support link assembly 4 for installing the tension locking assembly 3, a slide groove 3-3 is provided on the inner side surface of the roller side plate 4-1. The length direction of the slide groove 3-3 is parallel to the length direction of the trolley body 1. The end of the slide groove 3-3 away from the trolley body 1 is open, and the end close to the trolley body 1 is closed. A locking hole 3-4 parallel to the vertical direction is provided on the roller side plate 4-1. The bottom end of the locking hole 3-4 is connected to the closed end of the slide groove 3-3. The locking hole 3-4 is a stepped hole structure, and the hole section at the bottom is a threaded hole. Guide planes are provided at both ends of the roller shaft 2-4. The guide planes at both ends of the roller shaft 2-4 are slidably connected to the slide grooves 3-3 on the inner sides of the two roller side plates 4-1 respectively. A first threaded through hole is provided on the roller shaft 2-4. The axis of the first threaded through hole is perpendicular to the axis of the roller shaft 2-4 and parallel to the guide plane at the end of the roller shaft 2-4. The tensioning bolt 3-1 is threadedly connected to the first threaded through hole at the end of the roller shaft 2-4. The end of the tensioning bolt 3-1 is a bare rod section without threads; the end face of the bare rod section abuts against the closed end of the slide groove 3-3 of the roller side plate 4-1; by rotating the tensioning bolt 3-1, the roller shaft 2-4 can be driven to slide and the tensioning degree can be adjusted. The locking bolt 3-2 is threadedly connected to the internal thread in the locking hole 3-4, and the bottom end abuts against the side of the bare rod section of the tensioning bolt 3-1, thereby locking the tensioning bolt 3-1 to prevent the tensioning bolt 3-1 from rotating due to vibration during the operation of the narrow-belt sorting trolley.

[0035] In the supporting link assembly 4 where the tension locking assembly 3 is not installed, both ends of the roller shaft 2 - 4 of the conveying roller are fixed to the two roller side plates 4 - 1 respectively.

[0036] In this embodiment, the supporting link assembly 4 with the tension locking assembly 3 installed corresponds to the driven roller 2-2. The supporting link assembly 4 without the tension locking assembly 3 installed corresponds to the active roller 2-1.

[0037] The installation process of the narrow-band sorting trolley provided in this embodiment is as follows: first, the active roller 2-1 is installed between the two roller side plates 4-1, and after the conveyor belt 2-3 is inserted, the two roller side plates 4-1 corresponding to the active roller 2-1 are installed together with the active roller 2-1 on one end of the trolley body 1.

[0038] After the driven roller 2-2 is inserted through the conveyor belt 2-3, it is pushed in through the open end of the slide groove 3-3 left by the corresponding roller side plate 4-1. The two roller side plates 4-1 corresponding to the driven roller 2-2 are installed together with the driven roller 2-2 at the other end of the trolley body 1. The tightness of the conveyor belt 2-3 is adjusted by rotating the tension bolt 3-1; after the tightness is adjusted, the locking bolt 3-2 is installed in the locking hole 3-4 to lock the tension bolt 3-1 to prevent it from loosening.

[0039] When the tightness of the conveyor belt 2-3 needs to be adjusted, loosen the locking bolt 3-2, adjust the position of the conveyor roller by the tensioning bolt 3-1, and adjust the tightness of the conveyor belt 2-3. After the adjustment is completed, tighten the locking bolt 3-2.

[0040] In this embodiment, a secondary board 5 and an electrical installation board 6 are also installed on the trolley body 1. The electrical installation board 6 is used to install electrical components such as motor drivers, and can also be used to install a wire collection arm. The secondary board 5 and the electrical installation board 6 are both connected to the T-slot 1-2 on the side of the trolley body 1 through an L-shaped plate or a U-shaped plate. The vertical section of the L-shaped plate or the U-shaped plate is fixed to the T-slot 1-2 on the side of the trolley body 1 by bolts and nuts. In this way, the position of the secondary board 5 and the electrical installation board 6 can be freely adjusted along the length direction of the trolley body 1, making the installation of the narrow-band sorting trolley more flexible.

[0041] In some embodiments, a limit buckle is provided on the upper end surface of the roller side plate 4-1 to facilitate docking with the link frame 4-3 and the support guide plate 4-2, thereby improving installation accuracy and ensuring installation consistency.

[0042] In some embodiments, the vehicle body is made of profiles with compact structure and good rigidity; a shock-absorbing groove is set in the trolley body 1 of the aluminum profile to provide buffering and vibration absorption when the package falls.

[0043] In some embodiments, accordion covers can be connected to both sides of the narrow-band sorting trolley, so that the gaps between adjacent narrow-band sorting trolleys on the sorting machine are covered by the accordion covers to avoid the situation where goods are stuck at corners.
