Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and specifically relates to a screw processing feeding mechanism. Background Technology

[0002] When screws are heat-treated, they need to be transported in an orderly manner. A feeding mechanism is needed when transporting screw blanks. There are various traditional feeding structures, among which the push plate step feeder is the most commonly used feeding equipment.

[0003] Currently, push-plate step feeders are designed with a clamping cavity structure to ensure orderly screw conveying and that the screw column is in a downward position. The screw head is clamped at the top of the clamping cavity, and the screw column is perpendicular to the inside of the cavity under the action of gravity. Although this achieves the purpose of conveying, there are still some problems in use. For example, the size of the clamping cavity of traditional push-plate step feeders cannot be adjusted. When processing different batches of different screws, if the width of the clamping cavity is smaller than the column part of the screw, the screw cannot pass through the middle groove of the clamping cavity and descend vertically. If the nut part of the screw is smaller than the middle groove of the clamping cavity, the screw will not be clamped and will fall downward. The traditional solution is to replace the clamping cavity, but this is troublesome and time-consuming. Utility Model Content

[0006] The above technical solution is adopted: This utility model has a connecting sleeve that is rotatably connected to the connecting plate and slidably engaged with the connecting shaft. When the adjusting bolt is rotated, the connecting sleeve on the connecting plate can be moved on the surface of the connecting shaft without affecting the rotation of the connecting shaft and the connecting sleeve. This achieves the purpose of adjusting the distance between the synchronous belts of the synchronous pulleys on the two connecting shafts and the synchronous belts on the two connecting sleeves. The distance between the two synchronous belts is adjustable, which makes it convenient for screw heads of different sizes to be clamped vertically onto the screw post without the need to directly replace the corresponding clamping cavity, thus improving convenience.

[0007] The present invention is further configured such that a limiting arm is rotatably connected to the surface of the connecting shaft, and the limiting arm is bolted to the hopper.

[0008] The above technical solution is adopted: the connecting shaft is rotated and fixed.

[0009] The present invention is further configured such that a drive motor is provided on one side of the hopper, the drive motor is fixedly connected to the limiting arm, and the output end of the drive motor is bolted to the connecting shaft.

[0010] The above technical solution facilitates the rotation of the connecting shaft.

[0011] The present invention is further configured such that a bracket is fixedly connected to the bottom of the hopper, a hydraulic cylinder is fixedly sleeved inside the bracket, and the output end of the hydraulic cylinder is fixedly connected to the bottom of the push block.

[0012] The above technical solution facilitates the reciprocating movement of the pusher block into the hopper, thereby achieving the purpose of pushing materials.

[0013] The present invention is further configured such that a sliding block is slidably engaged in the slot of the connecting plate, and a tensioning wheel is rotatably connected to the back of the sliding block via a rotating shaft.

[0014] The above technical solution allows the tensioning pulley to easily tension the synchronous belt.

[0015] The present invention is further configured such that an adjusting bolt is threadedly connected to the top of the connecting plate, and one end of the adjusting bolt passes through a slot on the connecting plate and is rotatably connected to the sliding block.

[0016] By adopting the above technical solution, when the adjusting bolt is rotated, the sliding block can be moved to the position of the sliding block in the slot on the connecting plate for adjustment, thereby achieving the purpose of adjusting the position of the tensioning wheel.

[0017] The present invention is further configured such that a support frame is provided at the bottom of the hopper, and the support end of the support frame is fixedly connected to the hopper.

[0018] The above technical solution is adopted to support the hopper.

[0019] In summary, this utility model has the following beneficial effects:

[0020] This invention features a connecting sleeve that is rotatably engaged with a connecting shaft on a connecting plate. When the adjusting bolt is rotated, the connecting sleeve on the connecting plate can move on the surface of the connecting shaft without affecting the rotation of the connecting shaft and the connecting sleeve. This allows for adjustment of the distance between the synchronous belts of the synchronous pulleys on the two connecting shafts and the synchronous belts on the two connecting sleeves. The adjustable distance between the two synchronous belts facilitates the vertical clamping of screw heads of different sizes onto the screw post without the need to directly replace the corresponding clamping cavity, thus improving convenience.

A pusher block 3 is provided at the bottom of the hopper 1, with its pushing end penetrating into the interior of the hopper 1 and slidably connected to the partition block 2. Connecting shafts 4 are provided on both sides of the hopper 1, and a connecting plate 5 is provided on the front of the hopper 1. Two connecting sleeves 6 are rotatably connected to the connecting plate 5 and are slidably engaged with the connecting shafts 4. Synchronous pulleys 7 are fixedly sleeved on the surfaces of the connecting shafts 4 and the connecting sleeves 6. A synchronous belt 8 is drivingly connected between the two synchronous pulleys 7. An adjusting bolt 9, which is rotatably connected to the outer wall of the hopper 1, is threaded onto the front of the connecting plate 5. A limiting guide rod 10 is symmetrically fixedly connected to the front of the connecting plate 5 and slidably connected to it. A connecting sleeve 6 is slidably engaged with the connecting shaft 4 on the connecting plate 5. When the adjusting bolt 9 is rotated, the connecting sleeve 6 on the connecting plate 5 can be moved on the surface of the connecting shaft 4 without affecting the rotation of the connecting shaft 4 and the connecting sleeve 6. This achieves the purpose of adjusting the distance between the synchronous belt 8 driven by the synchronous pulley 7 on the two connecting shafts 4 and the synchronous belt 8 on the two connecting sleeves 6. The distance between the two synchronous belts 8 is adjustable, which makes it convenient for screw heads of different sizes to be clamped vertically on the screw post without the need to directly replace the corresponding clamping cavity, thus improving convenience.

[0031] refer to Figure 1 A limiting arm 11 is rotatably connected to the surface of the connecting shaft 4. The limiting arm 11 is bolted to the hopper 1. By setting the limiting arm 11, the connecting shaft 4 is rotatably limited and fixed.

[0032] refer to Figure 1 A drive motor 12 is provided on one side of the hopper 1. The drive motor 12 is fixedly connected to the limiting arm 11. The output end of the drive motor 12 is bolted to the connecting shaft 4. By providing the drive motor 12, it is convenient to drive the connecting shaft 4 to rotate.

[0033] refer to Figure 1 and Figure 6 A bracket 13 is fixedly connected to the bottom of the hopper 1. A hydraulic cylinder 14 is fixedly sleeved inside the bracket 13. The output end of the hydraulic cylinder 14 is fixedly connected to the bottom of the push block 3. By setting the bracket 13 and the hydraulic cylinder 14, the push block 3 can move back and forth into the hopper 1 to achieve the purpose of pushing materials.

[0034] refer to Figure 1 , Figure 2 and Figure 4 A sliding block 15 is slidably engaged in the slot on the connecting plate 5. The back of the sliding block 15 is rotatably connected to the tension wheel 16 via a rotating shaft. By setting the sliding block 15 and the tension wheel 16, the tension wheel 16 can easily tension the synchronous belt 8.

[0035] refer to Figure 1 and Figure 2The top of the connecting plate 5 is threaded with an adjusting bolt 17. One end of the adjusting bolt 17 passes through the slot on the connecting plate 5 and is rotatably connected to the sliding block 15. By setting the adjusting bolt 17, when the adjusting bolt 9 is rotated, the sliding block 15 can be moved to the position of the sliding block 15 in the slot on the connecting plate 5 for adjustment, thereby achieving the purpose of adjusting the position of the tension wheel 16.

[0037] Brief description of the usage process: When the hydraulic cylinder 14 is activated, it drives the pusher block 3 to move up and down repeatedly. The pusher block 3 pushes the screw stored inside the hopper 1 to the inclined wall opening of the hopper 1. The screw slides to the synchronous belt 8 between the synchronous pulleys 7 on the two connecting shafts 4, and then slides to the synchronous belt 8 between the synchronous pulleys 7 on the two connecting sleeves 6. The two synchronous belts 8 lock the screw nut in place, and the screw stud is vertically downward under the action of gravity. As the two synchronous belts 8 rotate synchronously, the screw is conveyed. When the adjusting bolt 9 is rotated, the connecting sleeve 6 on the connecting plate 5 can be moved on the surface of the connecting shaft 4 without affecting the rotation of the connecting shaft 4 and the connecting sleeve 6. This achieves the purpose of adjusting the distance between the synchronous belt 8 driven by the synchronous pulleys 7 on the two connecting shafts 4 and the synchronous belt 8 on the two connecting sleeves 6. The distance between the two synchronous belts 8 is adjustable.

[0038] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
