Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder technology, specifically a screw vibratory feeder with variable limit spacing. Background Technology

[0002] A vibratory feeder is a common automated device primarily used for the orientation and sorting of workpieces. It typically consists of a circular disc with spiral grooves and a vibration source. By adjusting the vibration frequency and amplitude, the workpieces can be moved in a specific direction and sequence. Vibratory feeders are widely used in industries such as electronics, hardware, toys, and pharmaceuticals for the sorting and conveying of parts on automated assembly lines.

[0003] Existing vibratory feeders can only screen screws of a fixed size in order to better screen screws. If you want to screen screws of different sizes, you have to choose other types of vibratory feeders. Therefore, they cannot adjust the screening spacing to screen screws of different sizes, and cannot meet the different needs of users. Utility Model Content

[0004] The purpose of this invention is to provide a screw vibratory feeder with variable limit spacing, so as to solve the problem mentioned in the background art that the currently used vibratory feeders cannot screen screws of different sizes by adjusting the screening spacing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw vibratory feeder with variable limit spacing, comprising: a vibratory feeder body and a discharge plate, wherein a motor housing is installed at the bottom of the vibratory feeder body, a base is installed at the bottom of the motor housing, and the discharge plate is connected to one side of the vibratory feeder body;

[0006] A fixed frame is installed on the top of the discharge tray. A guide block is connected through the middle of the fixed frame via a sliding groove. A guide plate is connected to the bottom of the guide block. Top blocks are connected through both sides of a set of guide blocks. A connecting block is connected to one side of the top block. A first telescopic block is connected to the bottom of the connecting block.

[0007] Preferably, a locking block that penetrates the guide block is connected to one side of the first telescopic block, and a movable spring is connected between the two sets of the first telescopic blocks.

[0008] Preferably, the locking block is engaged with a rack in the groove of a set of fixing frames.

[0009] Preferably, a connecting shaft is connected between the bottom of the motor housing and the top groove of the base, and an internal gear ring is sleeved on the outer side of the connecting shaft.

[0010] Preferably, a pull rod is connected through one side of the base, one end of the pull rod is connected to a rotating block, and a second telescopic block is provided on both sides of the rotating block.

[0011] Preferably, the second telescopic block is internally connected to a telescopic spring, and movable blocks are provided on both sides of the rotating block, with a limit block connected to one end of each movable block.

[0012] Preferably, a fixed block is sleeved on the outer side of the movable block, and a compression spring is connected between the movable block and the fixed block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the screw vibratory feeder with variable limit spacing is in use, it can squeeze the top block according to the size of the screw. When the top block moves towards the guide block, it will cooperate with the connecting block and the first telescopic block to pull the locking block to move, so that the locking block does not limit the rack in the slide groove of the fixed frame. At this time, the guide block can drive the bottom guide plate to slide. By adjusting the position between the two sets of guide plates, it can guide screws of different sizes, thereby facilitating the screening of screws of different sizes. This is the usage feature of the screw vibratory feeder with variable limit spacing.

[0014] 1. In use, the screw vibratory feeder with variable limit spacing can press the top block into the guide block according to the size of the screw. The movement of the top block will cause the locking block to retract into the guide block through the connecting block and the first telescopic block, and separate from the rack in the slide groove of the fixed frame. At this time, the guide block can drive the guide plate to slide along the fixed frame. By adjusting the distance between the two sets of guide plates, the guide plate can guide screws of different sizes, thereby meeting the different usage needs of users.

[0015] 2. In use, the screw vibratory feeder with variable limit spacing can be operated by pulling the lever according to the screw discharge angle, which causes the lever to drive the rotating block to rotate. When the rotating block rotates, it does not squeeze the moving block. Then, under the reset action of the compression spring, the limit block separates from the internal gear ring. At this time, the motor box and the vibratory feeder body can be rotated, so as to easily adjust the direction of the discharge plate according to the needs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a screw vibratory feeder with variable limiting distance, comprising: a vibratory feeder body 1 and a discharge plate 4, a motor box 2 is installed at the bottom of the vibratory feeder body 1, a base 3 is installed at the bottom of the motor box 2, and the discharge plate 4 is connected to one side of the vibratory feeder body 1.

[0026] A fixed frame 5 is installed on the top of the discharge plate 4. A guide block 6 is connected through the middle of the fixed frame 5 via a sliding groove. A guide plate 7 is connected to the bottom of the guide block 6. Top blocks 8 are connected through both sides of a set of guide blocks 6. A connecting block 9 is connected to one side of the top block 8. A first telescopic block 10 is connected to the bottom of the connecting block 9. A locking block 11 that passes through the guide block 6 is connected to one side of the first telescopic block 10. A movable spring 12 is connected between the two sets of first telescopic blocks 10. A rack 13 is engaged between the locking block 11 and the groove of a set of fixed frames 5. Two sets of racks 13 are symmetrically installed about the center line of the fixed frame 5.

[0027] In practical implementation, when the spacing of the guide plate 7 needs to be adjusted, the top blocks 8 on both sides of the middle guide block 6 are simply pressed inward. When the top blocks 8 retract into the guide block 6, they will cause the locking blocks 11 to retract into the guide block 6 through the connecting block 9 and the first telescopic block 10. At the same time, the two sets of first telescopic blocks 10 will press the middle movable spring 12. When the locking blocks 11 retract into the guide block 6, they will separate from the rack 13 in the slide groove of the fixed frame 5. Without the locking blocks 11 engaging with the rack 13 in the slide groove of the fixed frame 5, the guide block 6 can slide along the slide groove that runs through the middle of the fixed frame 5. When the guide block 6 slides, it will drive the bottom guide plate 7 to slide, and the guide plate 7 will cause the guide blocks 6 on both sides to slide along the corresponding fixed frame 5. At this time, the position of the guide plate 7 can be adjusted. By adjusting the guide plate 7, screws of different sizes can be guided and conveyed.

[0028] When the guide plate 7 is adjusted to the appropriate position, the top block 8 can be released. At this time, the movable spring 12 will reset and drive the locking block 11 to reset through the first telescopic block 10, so that the locking block 11 reconnects with the rack 13 in the slide groove of the fixed frame 5. Due to the limiting effect of the locking block 11 and the rack 13, the guide block 6 can be fixed. At this time, the guide plate 7 can no longer slide along the fixed frame 5.

[0029] See Figures 1-5 It can be seen that during use, the top block 8 can be pressed into the guide block 6 as needed, so that the locking block 11 is separated from the rack 13 in the groove of the fixing frame 5. Without the limiting effect of the locking block 11 and the rack 13, the guide block 6 can drive the guide plate 7 to slide along the fixing frame 5. By adjusting the position of the guide plate 7, it can guide screws of different sizes, thereby meeting the different usage needs of users.

[0030] A connecting shaft 14 is connected between the bottom of the motor housing 2 and the top groove of the base 3. An internal gear ring 15 is sleeved on the outside of the connecting shaft 14. A pull rod 16 is connected through one side of the base 3. A rotating block 17 is connected to one end of the pull rod 16. A second telescopic block 18 is provided on both sides of the rotating block 17. A telescopic spring 19 is connected inside the second telescopic block 18. A movable block 20 is provided on both sides of the rotating block 17. A limit block 21 is connected to one end of the movable block 20. A fixed block 22 is sleeved on the outside of the movable block 20. A compression spring 23 is connected between the movable block 20 and the fixed block 22. The center of the rotating block 17 is connected to the groove of the base 3 through a rotating shaft.

[0031] In practical implementation, when the discharge direction of the entire vibratory feeder needs to be adjusted, the pull rod 16 on one side of the base 3 can be pulled, causing the pull rod 16 to drive the rotating block 17 to rotate. Movable blocks 20 are provided on both sides of the rotating block 17, and fixed blocks 22 are sleeved on the outer side of the movable blocks 20. A limit block 21 is also installed on one side of the movable block 20. When the rotating block 17 rotates, it does not compress the movable block 20, but instead compresses the second telescopic blocks 18 on both sides of the rotating block 17, thus... The second telescopic block 18 retracts and squeezes the internal telescopic spring 19. At this time, the rotating block 17 does not squeeze the movable block 20. Under the reset action of the compression spring 23, the movable block 20 will move along the fixed block 22. At the same time, the limiting block 21 on one side of the movable block 20 will separate from the groove of the internal gear ring 15. Without the limiting block 21 and the internal gear ring 15 limiting the connecting shaft 14, the motor box 2 at the top and the vibrating plate body 1 can be rotated through the connecting shaft 14. At this time, the discharge direction can be adjusted.

[0032] Conversely, the pull rod 16 can be released, and under the reset action of the telescopic spring 19 and the second telescopic block 18, the rotating block 17 will rotate in the opposite direction. When the rotating block 17 rotates in the opposite direction, it will squeeze the movable block 20. At this time, the movable block 20 will push the limiting block 21 to engage with the internal gear ring 15. Due to the limiting action of the limiting block 21 and the internal gear ring 15 on the connecting shaft 14, the connecting shaft 14 can not rotate, thereby ensuring the stability of the motor box 2 and the vibratory plate body 1.

[0033] See Figure 1 , Figure 6 and Figure 7 As can be seen, when in use, the lever 16 can be pulled according to the usage requirements, so that the lever 16 drives the rotating block 17 to rotate. When the rotating block 17 rotates, the internal gear ring 15 is not limited by the movable block 20 and the limiting block 21. Then the motor box 2 and the vibrating plate body 1 can be rotated, so that the direction of the discharge plate 4 can be adjusted according to the requirements without having to move the motor box 2 back and forth to adjust the direction.

[0034] In summary: When using this variable limit spacing screw vibratory feeder, the motor housing 2 can be placed in a stable position using the base 3. The screws to be screened are poured into the vibratory feeder body 1, and then the motor in the motor housing 2 is started. At this time, the motor will drive the vibratory feeder body 1 to rotate. When the vibratory feeder body 1 rotates, it will continuously convey the screws. At this time, screws that are too large or too small cannot be conveyed. The qualified screws after screening will fall into the collection box at the bottom through the discharge plate 4, thus facilitating the collection of screws. This is the characteristic of the use of the variable limit spacing screw vibratory feeder. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
