DETAILED DESCRIPTION

[0023] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clear and obvious, the utility model will be further described in detail below in combination with drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0024] Thus, one feature described in the specification can be used to explain one embodiment of the application, but not necessarily every embodiment of the application. Moreover, it should be noted that the specification describes many features. Although certain features can be combined together in one embodiment, these features can also be used in other embodiments that do not explicitly mention the combination. Thus, unless otherwise noted, the described combination is not intended to be limiting.

[0025] The principles of the present application will be described in detail below with reference to the accompanying drawings and examples.

[0026] The utility model provides a desktop screw aligner, including the box body 1 with the inner chamber, the inner chamber is suspendedly arranged with a conveying chain 2, the top wall of box body 1 is provided with skylight 11 in conveying chain 2 front section upper side, and the periphery of conveying chain 2 rear section is equipped with a roller 3;Conveying chain 2 is composed of a plurality of conveying units 4 front and rear hinged string connection, and each conveying unit 4 is equipped with aligning hole 41, and the cylinder wall of roller 3 is equipped with stirring plate 31. Desktop screw aligner is small in size and can be placed on the workbench, after pouring screws from skylight 11, the screw is constantly poured on conveying chain 2 by roller 3, and individual screw can be inserted into the aligning hole 41 of conveying unit 4 to realize alignment, and then the screw is conveyed to the front end one by one for taking. The back of box body 1 is equipped with support 12, the support 12 is equipped with roller motor 5, the back of roller 3 is drivingly connected with the rotating shaft of roller motor 5, and is driven to rotate by roller motor 5.

[0027] In the embodiment, 6 stirring plates 31 are arranged around the conveying chain 2, 3 of which are provided with a brush 32 for brushing off the screws, the brush 32 is arranged at the front end of the stirring plate 31 and extends in the same direction as the conveying chain 2. With the rotation of the roller 3, the 6 stirring plates 31 take turns to bring the screws at the bottom to the top of the conveying chain 2 and pour them on the conveying chain 2, increasing the probability of the screws being inserted into the aligning hole 41. When the conveying unit 4 moves away from the roller 3, the brush 32 sweeps off the screws that are not inserted into the aligning hole 41 but left on the conveying chain 2.

[0028] In the embodiment, one side of the top of the conveying unit 4 in the left-right direction is provided with a convex strip 42. The convex strip 42 makes the conveying side higher, and if the screw falling onto the convex strip 42 does not directly slide off, it will tilt to the other side of the conveying unit 4, making it easier for the screw to be inserted into the aligning hole 41.

[0029] The front part of the conveying chain 2 is in transmission connection with the driving gear 21, and the rear part is in transmission connection with the driven gear 22. The driving gear 21 is in transmission connection with the chain motor 23 installed outside the box body 1 for driving the driving gear 21 through a shaft rod penetrating out of the box body 1. The first baffle 24 is arranged on one side of the conveying chain 2 in the left-right direction, and the second baffle 25 is arranged on the other side. The front ends of the first baffle 24 and the second baffle 25 are fixedly connected with the front inner wall of the box body 1. The driving gear 21 and the driven gear 22 are rotatably arranged between the first baffle 24 and the second baffle 25. The first baffle 24 and the second baffle 25 support the conveying chain 2, so that the conveying chain 2 is arranged in a suspended manner and avoids blocking the rotation of the stirring plate 31 and the brush 32. In addition, the first baffle 24 and the second baffle 25 also prevent the screws from entering the conveying chain 2 from the side and causing the conveying chain 2 to be stuck.

[0030] In the embodiment, the front part of the skylight 11 is provided with the taking hole 6. The side of the taking hole 6 is provided with the vertically extending guide plate 7. The front part of the guide plate 7 is provided with a pair of guide strips 71. The guide plate 7 and the pair of guide strips 71 surround a bucket-shaped groove 72. The bottom of the bucket-shaped groove 72 is opposite to the taking hole 6. When the user takes the screw, the screwdriver is inserted into the taking hole 6 to take the screw. The bucket-shaped groove 72 guides the screwdriver to smoothly enter the taking hole 6.

[0031] In the embodiment, the bottom of the inner cavity is provided with the slope surface 13 which is high in front and low in back, so as to guide the screw brushed off by the brush 32 to roll back into the roller 3.

[0032] The above only describes the preferred embodiments of the utility model and does not limit the utility model. Any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
