Description

Technical Field

[0001] This utility model relates to a hand-cranked screw sorter. Background Technology

[0002] Bolts are important mechanical components and are widely used in the machinery industry. In the production, processing and daily use of bolts, such as in laboratories, workshops and repair shops, bolts usually need to be screened in order to classify bolts of different specifications for use. Currently, most bolt screening is done manually, which is slow, time-consuming and labor-intensive, and prone to errors. Utility Model Content

[0003] The purpose of this invention is to provide a hand-cranked screw sorter to solve the technical problem of time-consuming and laborious manual sorting.

[0004] The technical solution of this utility model is as follows: The hand-cranked screw sorter includes:

[0005] Storage mechanism for storing screws to be screened;

[0006] The feeding mechanism, which connects with the storage mechanism, includes a fixed step plate and a movable step plate. The fixed step plate includes multiple fixed plates arranged at intervals in sequence. The upper ends of each fixed plate and each movable plate increase in height from upstream to downstream. The movable step plate includes a transmission block and multiple movable plates fixed at intervals on the transmission block. The movable plates and fixed plates slide in a cross-sliding fit. The transmission block is driven by a cam mechanism to move linearly back and forth in the vertical direction. The movable plate has a lower station for material to fall onto its upper end surface and an upper station for making its upper end surface higher than the upper end surface of the adjacent fixed plate so that the material falls from the movable plate onto the fixed plate. The upper end surfaces of both the fixed plate and the movable plate are inclined surfaces that slope downwards towards the downstream direction.

[0007] The screening mechanism, which is connected to the feeding mechanism, includes multiple screening units spaced apart in the vertical direction. Each screening unit includes a screening inclined slide that is inclined downwards and downstream. The screening inclined slide has a feeding channel. The width of the feeding channel is smaller than the diameter of the corresponding screw head and larger than the outer diameter of the next level screw head. The width of the feeding channel of each screening unit decreases from top to bottom.

[0008] The collection mechanism includes collection chambers that correspond one-to-one with the screening units, and the upper openings of the collection chambers are positioned vertically and vertically corresponding to the outlets of the corresponding screening inclined slides.

[0009] The beneficial effects of this technical solution are as follows: When using the hand-cranked screw sorter, the screws to be sorted are poured into the storage mechanism. Some screws fall onto the upper surface of the first movable plate of the feeding mechanism and are blocked by the first fixed plate. After the cam mechanism is activated, it drives the movable step plate to move linearly back and forth in the vertical direction. When the first movable plate moves the screws on it upwards and passes the adjacent first fixed plate, due to the slope of the movable plate, the screws automatically fall onto the upper surface of the fixed plate and are blocked by the second movable plate. As the second movable plate falls, when it is lower than the first fixed plate, due to the slope of the upper surface of the first fixed plate, the screws fall onto the second movable plate and are blocked by the second fixed plate. A fixed plate blocks the flow, and the above process is repeated sequentially, causing the material to be quantitatively conveyed upwards until it reaches the inlet of the screening mechanism. The material falls into the top-level screening unit of the screening mechanism. Materials with a diameter smaller than the feeding channel fall, while screws with a diameter larger than the width of the feeding channel are retained. Due to their own weight and the screening inclined slide, the screws will lean on the screening inclined slide with their screw heads and slide down it, then fall into the collection bin corresponding to the screw size. The screws falling from the feeding channel of the first-level screening unit are screened again by the feeding channel of the second-level screening unit, retaining the screws of the corresponding size, while the remaining screws with smaller diameters continue to fall. The same principle as the first-level screening unit is used to achieve the step-by-step screening of screws by diameter. Therefore, this technical solution can screen and store screws according to their diameter. The entire process relies on the width of the feeding channel for automatic screening. The feeding process adopts a "staircase" method for quantitative conveying, avoiding the problem of clogging caused by screening too many at once. The structure of the feeding channel and the screening inclined slide, which is similar to a "T" cross-section, allows the screws to slide along it in the same posture. This solution has the advantages of simple structure, convenient operation, high screening efficiency, and high screening quality.

[0010] Based on the above scheme, the following improvements are made: the material storage mechanism includes a discharge ramp that slopes downward from upstream to downstream.

[0011] The beneficial effect of this technical solution is that it ensures that materials can automatically flow to the first movable plate.

[0012] Based on the above scheme, the following improvements are made: the screening unit includes two symmetrically spaced baffles, and inclined steps are respectively opened on the opposite surfaces of the two baffles to form the screening inclined slide.

[0013] Based on the above scheme, the following improvement is made: the upper surface of the baffle is an inclined surface that slopes downward toward the inward side.

[0014] Based on the above scheme, the following improvements are made: the transmission block has a rectangular groove, and the cam mechanism includes a rotating shaft, a cam, and a crank handle. The cam is located in the rectangular groove, and when the crank handle is rotated, it drives the rotating shaft and the cam to rotate.

[0015] Based on the above scheme, the following improvement is made: the exit of the inclined slide is selected to be a rectangular opening. Attached Figure Description

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0025] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0026] A specific embodiment of the hand-cranked screw sorter of this utility model is as follows: Figures 1-5 As shown, the hand-cranked screw sorter includes a storage mechanism 2, a feeding mechanism 3, a screening mechanism 4, and a collection mechanism 5 arranged sequentially from upstream to downstream.

[0027] The storage mechanism 2 is used to store screws to be screened. It has a drawer-like shape and a bottom plate that slopes downwards from upstream to downstream. This ensures that the material can automatically flow to the first movable plate 322.

[0028] The feeding mechanism 3 is connected to the storage mechanism 2. The feeding mechanism 3 includes a fixed step plate and a movable step plate 32. The fixed step plate includes multiple fixed plates 311 arranged at intervals. In this embodiment, there are three movable plates 322 and two fixed plates 311. The upper ends of each fixed plate 311 and each movable plate 322 increase in height from upstream to downstream. The movable step plate 32 includes a transmission block 321 and multiple movable plates 322 fixed at intervals on the transmission block 321. The movable plates 322 and the fixed plates 311 slide in a cross-sliding manner. The thickness of each movable plate 322 and the fixed plate 311 is the same, and the spacing between adjacent plates is consistent. The transmission block 321 is connected by a convex... The wheel mechanism 33 drives the material to reciprocate linearly in the up-down direction. The movable plate 322 has a lower station for material to fall onto its upper surface and an upper station for material to fall from the movable plate 322 onto the fixed plate 311, with its upper surface higher than the upper surface of the adjacent fixed plate 311. The upper surfaces of both the fixed plate 311 and the movable plate 322 are inclined surfaces sloping downwards towards the downstream direction. The transmission block 321 has a rectangular groove 3211. The cam mechanism 33 includes a rotating shaft 332, a cam 333, and a crank handle 331. The cam 333 is located in the rectangular groove 3211. When the crank handle 331 rotates, it drives the rotating shaft 332 and the cam 333 to rotate. The outlet of the screening inclined slide 4112 is a rectangular opening 4114.

[0029] The screening mechanism 4 is connected to the feeding mechanism 3 and includes a multi-stage screening unit 41 arranged at intervals along the vertical direction. In this embodiment, there are four stages. The screening unit 41 includes a screening inclined slide 4112 arranged downwards and downstream. The screening inclined slide 4112 has a feeding channel 4113. The width of the feeding channel 4113 is smaller than the diameter of the corresponding screw head and larger than the outer diameter of the next level screw head. The width of the feeding channel 4113 of each screening unit 41 decreases from top to bottom. The screening unit 41 includes two baffles 411 arranged symmetrically at intervals. Inclined steps 4111 are respectively opened on the opposing surfaces of the two baffles 411 to form the screening inclined slide 4112. The upper surface of the baffle 411 is an inclined surface that slopes downwards towards the inward side.

[0030] The collection mechanism 5 includes a collection chamber 51 that corresponds one-to-one with the screening unit 41. The upper opening of the collection chamber 51 is vertically aligned with the outlet of the corresponding screening inclined slide 4112.

[0031] When using the hand-cranked screw sorter, the screws to be sorted are poured into the storage mechanism 2. Some screws fall onto the upper surface of the first movable plate 322 of the feeding mechanism 3 and are blocked by the first fixed plate 311. After the cam mechanism 33 is activated, the cam mechanism 33 will drive the movable step plate 32 to move linearly back and forth in the up and down direction. When the first movable plate 322 moves the screws on it upwards and passes the adjacent first fixed plate 311, due to the slope of the movable plate 322, the screws on it automatically fall onto the upper surface of the fixed plate 311 and are blocked by the second movable plate 322. As the second movable plate 322 falls, when the second movable plate 322 is lower than the first fixed plate 311, due to the slope of the upper surface of the first fixed plate 311, the screws will fall onto the second movable plate 322 and be blocked by the second fixed plate. 311 is blocked, and then the above process is repeated in sequence, so that the material is quantitatively conveyed upward until it moves to the inlet of the screening mechanism 4. The material falls into the screening unit 41 of the uppermost level of the screening mechanism 4. The material with a diameter smaller than the feeding channel 4113 falls, and the screw with a diameter larger than the width of the feeding channel 4113 is left. Due to its own weight and the screening inclined slide 4112, the screw will rely on the screw head to support the screening inclined slide 4112 and slide down it, and then fall into the collection bin 51 corresponding to the screw of that specification. The screws falling from the feeding channel 4113 of the first-level screening unit 41 are screened again by the feeding channel 4113 of the second-level screening unit 41, retaining the screws of the corresponding specification, and the remaining screws with smaller diameter specifications continue to fall. The same principle as the first-level screening unit 41 is used to achieve the step-by-step screening of screws by diameter. Therefore, this technical solution can screen and store screws according to their diameter. The entire process relies on the width of the feeding channel 4113 for automatic screening. The feeding process adopts a "staircase" method for quantitative conveying, avoiding the problem of blockage caused by screening too many at once. The structure of the feeding channel 4113 and the screening inclined slide 4112 forming a "T"-shaped cross-section allows the screws to slide along it in the same posture. This solution has the advantages of simple structure, convenient operation, high screening efficiency, and high screening quality.
