Description

Technical Field

[0001] This utility model relates to the field of logistics sorting technology, and in particular to a high-speed narrow-strip sorting trolley. Background Technology

[0002] Sorting is the process of categorizing and stacking goods according to their type and the order in which they enter and leave the warehouse. Sorting is a preparatory step for improving and supporting delivery, and it is an inevitable extension of competition among different delivery companies to improve their own economic efficiency. Therefore, it can also be said that sorting is a necessary requirement for the development of delivery into more advanced forms.

[0003] A search revealed that Chinese Patent Publication No. CN221679804U discloses a narrow-belt sorting machine, relating to the field of logistics sorting technology. The machine includes a fixed frame, an internal drive shaft, an external belt, and an external push block. A fixed rod is fixedly connected to the outer surface of the drive shaft, a sliding frame is slidably connected to the outer surface of the fixed rod, and a fixed block is fixedly connected to the outer surface of the sliding frame. A fixed groove is formed inside the drive shaft, and a fixed bolt is threaded onto the outer surface of the fixed rod. Through the cooperation between the sliding frame, the fixed bolt, and the fixed block, when the belt needs to be replaced, the two sets of drive shafts can be separated from the middle. Then, the belt is fitted onto the drive shafts on both sides from the middle position. After installation, the fixed rod and fixed frame can be moved by the fixed bolt, allowing the drive shafts on both sides to be connected. This enables rapid belt replacement within the narrow-belt sorting machine.

[0004] While the above solution has the advantage of quick belt replacement, the belt may loosen over time, making it impossible to transport items. Furthermore, the solution does not include a cleaning mechanism to clean the belt surface, resulting in a poor working environment.

[0005] Therefore, there is an urgent need to provide a high-speed, narrow-band sorting cart to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the above-mentioned existing technology, such as the belt becoming loose during long-term use, which makes it impossible to transport items, and the lack of a cleaning structure to clean the belt surface, resulting in a poor working environment. The present invention provides a high-speed narrow belt sorting trolley.

[0007] To solve the above-mentioned technical problems, the present invention provides a high-speed narrow-belt sorting trolley, including a base plate, a conveyor roller disposed on the top of the base plate, and a narrow belt disposed on the outside of the conveyor roller. A tensioning component is disposed at the bottom of the narrow belt, and a cleaning component is disposed on the side of the tensioning component.

[0008] The tensioning assembly includes a movable frame movably disposed at the bottom of the base plate, a guide unit installed at the top of the movable frame, and an adjustment unit disposed at the bottom of the movable frame;

[0009] The cleaning assembly includes a fixed base installed on the inner side wall of the movable frame, a cleaning scraper disposed on the top of the fixed base, and a connector disposed between the cleaning scraper and the fixed base.

[0010] The present invention is further configured such that: a support rod is fixedly connected to the bottom corner of the base plate, and a caster wheel is movably connected to the bottom of each support rod.

[0011] The present invention is further configured such that: there are multiple narrow strips, which are equidistantly distributed on the top of the base plate, and the number of tensioning components is the same as the number of narrow strips.

[0012] The present invention is further configured such that: the guide unit includes a rotating shaft movably connected to the side wall of the movable frame and a guide wheel installed on the side of the rotating shaft, the bottom of the guide wheel being in contact with the surface of the narrow strip.

[0013] The present invention is further configured such that: the adjustment unit includes a connecting frame installed at the bottom of the movable frame, a support plate fixedly installed at the bottom of the connecting frame, a buffer portion installed between the support plate and the connecting frame, and a pressing portion installed on the outside of the support plate.

[0014] The present invention is further configured such that: there are two sets of buffer parts, and the two sets of buffer parts are arranged opposite to each other on the outside of the connecting frame;

[0015] The buffer section includes a slide rod installed at the bottom of the base plate, a slide sleeve movably disposed on the outside of the slide rod, and an elastic element disposed on the top of the slide sleeve. The slide sleeve is installed on the outer side of the connecting frame.

[0016] The present invention is further configured such that: the extrusion part includes a fixed frame installed at the bottom of the support plate, a threaded rod threaded to the bottom of the fixed frame, a threaded sleeve threaded to the outside of the threaded rod, a collar installed on the outer surface of the threaded sleeve, a guide rod movably disposed inside the collar, and a buffer disposed outside the guide rod, wherein a limit block is installed at the bottom of the guide rod.

[0017] The present invention is further configured as follows: an extension plate inside the connector and an extrusion member disposed at the bottom of the extension plate, and the cleaning scraper is installed on the top of the extension plate.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model, through the setting of a tensioning component, in conjunction with the rotation of the threaded rod, causes the threaded sleeve to slide along the length of the threaded rod under the action of the threaded pair. When the threaded sleeve slides, under the action of the limiting block and the buffer, the collar pulls the guide rod to move, thereby pulling the connecting frame to move and adjusting the position of the guide wheel, thereby changing the tension of the narrow belt, which facilitates the conveying of items. In addition, during the adjustment process, the elastic force of the sliding sleeve and the elastic element alleviates the adjustment force, avoiding excessive tension that could cause the narrow belt to break.

[0020] 2. The present invention, through the cleaning component, pushes the extension plate upward under the elastic squeezing action of the extruder during the rotation of the narrow belt, so that the end of the cleaning scraper is always in contact with the surface of the narrow belt, thereby cleaning the surface of the narrow belt. The cleaned impurities will fall into the connecting frame, which is convenient for subsequent cleaning and optimizes the working environment. Attached Figure Description

[0030] Each base plate 1 has a support rod 11 fixedly connected to its bottom corner, and each support rod 11 has a caster wheel 12 movably connected to its bottom.

[0031] There are multiple narrow bands 3, which are equidistantly distributed on the top of the base plate 1. The number of tensioning components 4 is the same as the number of narrow bands 3.

[0032] The guide unit 42 includes a rotating shaft 421 movably connected to the side wall of the movable frame 41 and a guide wheel 422 installed on the side of the rotating shaft 421. The bottom of the guide wheel 422 contacts the surface of the narrow belt 3. Preferably, there are multiple sets of guide units 42, which are equidistantly distributed on the side wall of the movable frame 41. By setting multiple sets of guide units 42, the narrow belt 3 is stably guided.

[0033] The adjustment unit 43 includes a connecting frame 431 installed at the bottom of the movable frame 41, a support plate 432 fixedly installed at the bottom of the connecting frame 431, a buffer portion 433 disposed between the support plate 432 and the connecting frame 431, and a pressing portion 434 disposed on the outside of the support plate 432.

[0034] There are two sets of buffer sections 433, and the two sets of buffer sections 433 are arranged opposite to each other on the outside of the connecting frame 431.

[0035] The buffer part 433 includes a slide rod 4331 installed at the bottom of the base plate 1, a slide sleeve 4332 movably disposed on the outside of the slide rod 4331, and an elastic element 4333 disposed on the top of the slide sleeve 4332. The slide sleeve 4332 is installed on the outer side of the connecting frame 431, and preferably the elastic element 4333 is a spring.

[0036] The compression part 434 includes a fixed frame 4341 installed at the bottom of the support plate 432, a threaded rod 4342 threaded to the bottom of the fixed frame 4341, a threaded sleeve 4343 threaded to the outside of the threaded rod 4342, a collar 4344 installed on the outer surface of the threaded sleeve 4343, a guide rod 4345 movably disposed inside the collar 4344, and a buffer 4346 disposed outside the guide rod 4345.

[0037] The connector 53 includes an extension plate 531 movably disposed inside the fixed base 51 and an extrusion member 532 disposed at the bottom of the extension plate 531. The cleaning scraper 52 is installed on the top of the extension plate 531. Preferably, the extrusion member 532 is a compression spring, and there are multiple extrusion members 532, which are equidistantly distributed at the bottom of the extension plate 531.

[0038] When the tension of the narrow band 3 needs to be adjusted, firstly, by rotating the threaded rod 4342, the threaded sleeve 4343 slides along the length of the threaded rod 4342 under the action of the threaded pair. When the threaded sleeve 4343 slides, the collar 4344 pulls the guide rod 4345 to move under the action of the limit block 4347 and the buffer 4346, thereby pulling the connecting frame 431 to move, thereby adjusting the position of the guide wheel 422, thereby changing the tension of the narrow band 3. During the adjustment process, the elastic force of the sliding sleeve 4332 and the elastic element 4333 relieves the adjustment force and avoids the narrow band 3 from breaking due to excessive tension.

[0039] As the narrow strip 3 rotates, under the elastic squeezing action of the extruder 532, it pushes the extension plate 531 upward, so that the end of the cleaning scraper 52 is always in contact with the surface of the narrow strip 3, thereby cleaning the surface of the narrow strip 3. The cleaned-off impurities will fall into the connecting frame 431 for easy subsequent cleaning.
