Description

Technical Field

[0001] The utility model relates to the technical field of screw feeders, in particular to a high-efficiency feeding device for a screw feeder. Background Art

[0002] The roller screw feeder is a device that can continuously feed screws. When the roller screw feeder is in operation, the screws are intermittently dropped onto the retaining pieces through the feeding plate on the roller, and the screws are aligned on the retaining pieces and fed into the track. However, the retaining pieces on the existing roller screw feeders are only simple inclined plates. The screws will fall off from between the two retaining pieces before they are aligned, reducing the efficiency of screw feeding. At the same time, although some screws will enter the track, they will be in a tilted state, affecting the unloading of the roller screw feeder and even causing the roller screw feeder to work abnormally.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 5 As shown, in the present embodiment, a high-efficiency feeding device for a screw feeder comprises a roller screw feeder body 1, a vibration motor 2 is fixedly installed inside the roller screw feeder body 1, a distributor 3 is fixedly installed at the discharging position of the roller screw feeder body 1, a roller 4 is installed at the feeding position of the roller screw feeder body 1, a track 5 for sequentially feeding the screws is fixedly installed in the middle of the roller screw feeder body 1, adjustment plates 6 for positioning the screws from dispersion to aggregation are symmetrically fixedly installed on both sides of the feeding end of the track 5, the middle part of the adjustment plate 6 is stepped and narrowed, and a push-off block 7 for pushing down the crooked screws is installed on the top outer side of the track 5, and the vertical screw can pass through the middle part of the push-off block 7.

[0022] like Figures 1 to 5 As shown, an inclined sloping plate 8 is integrally fixedly mounted on the top of the adjustment plate 6 .

[0023] The amount by which the screw enters between the adjustment plates 6 can be increased.

[0024] like Figures 1 to 5 As shown, vertical plates 9 are fixedly installed in an equidistant manner in the middle of the adjustment plate 6, and two vertical plates 9 adjacent to each other are staggered.

[0025] The area occupied by the screw sliding down can be gradually reduced to push the crooked screw to move to the middle.

[0026] like Figures 1 to 5 As shown, the connection between the plurality of vertical plates 9 is provided with rounded corners 10 .

[0027] Place screws to clamp the joints between the vertical plates 9.

[0028] like Figures 1 to 5As shown, a triangle plate 11 is integrally fixed to the bottom of the adjustment plate 6, the bottom of the triangle plate 11 is horizontally arranged, the lower surface of the triangle plate 11 is in contact with the lower surface of the track 5, and the distance between the lowest ends of the two triangle plates 11 is slightly larger than the diameter of the screw head.

[0029] When the screw falls to the triangular plate 11 , the position of the screw can be finally positioned, and the screw rod of the screw can be limited to the track 5 .

[0030] like Figures 1 to 5 As shown, a limit rod 12 is symmetrically fixedly installed on one side of the push-off block 7, a mounting block 13 is fixedly installed on one side of the track 5, a limit hole 14 is opened in the middle of the mounting block 13, the limit rod 12 is slidably connected to the limit hole 14, a return spring 15 is sleeved on the outer side of one end of the limit rod 12 away from the push-off block 7, one end of the return spring 15 is fixedly connected to the end of the limit rod 12 away from the push-off block 7, the other end of the return spring 15 is fixedly connected to one side of the mounting block 13, and a groove 16 is opened in the middle of the top end of the push-off block 7.

[0031] When the screw enters the track 5 and passes through the push-off block 7, the push-off block 7 will push the screw on the surface of the track 5 or the screw that has entered the track 5 but is not stably upright, that is, the screw that has not passed the middle of the push-off block 7 will be pushed, and the screw can be pushed out of the track 5. The vibrating return spring 15 and the push-off block 7 can push the skewed screw and slide it out of the track 5, so as to prevent the screw from getting stuck on the track 5.

[0032] like Figures 1 to 5 As shown, an inclined stripping plate 17 is fixedly mounted on one side of the push-off block 7 close to the limiting rod 12 , and the stripping plate 17 is arranged below the upper surface of the track 5 .

[0033] The screw that has fallen off can be slid down along the stripper plate 17 to prevent it from being stuck in the return spring 15 .

[0034] The utility model provides a high-efficiency feeding device for a screw feeder, and the specific working principle is as follows:

[0035] When the device is in use, the screws are poured into the feeding position of the roller 4, and the roller 4 is driven to rotate. The screws dug by the inclined U groove on the roller 4 will enter the adjustment plate 6. Under the action of gravity, the screws between the two adjustment plates 6 will slide and fall between the inclined plates 8. When passing between the staggered vertical plates 9, the steps formed by the vertical plates 9 will gradually push the screws, and slowly push the intricate screws to the middle position. The inclined screws are placed in the center, and under the action of the screw's own gravity, the screw rod of the screw will be at the bottom and the screw head of the screw will be at the top, which can increase the number of screws entering the track 5 and improve the feeding efficiency of the screws.

[0036] After the screw enters the track 5, the vibration of the track 5 by the vibration motor 2 will drive the screw to move forward. When passing through the push-off block 7, the push-off block 7 will push the screw on the surface of the track 5 or the screw that has entered the track 5 but is not stably upright, that is, the screw that has not passed the middle of the push-off block 7 will be pushed, which can push the screw to swing or push the screw that cannot swing out of the track 5. When the track 5 vibrates, the reset spring 15 and the push-off block 7 can also vibrate, and the vibrating push-off block 7 will facilitate the pushing of the screw. The vibration of the reset spring 15 can reciprocate and drive the push-off block 7 to move, which is used to push the crooked screw and slide out of the track 5. The screw moves forward to the distributor 3 for distribution and falls into the air pipe to complete the operation.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
