DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5 In the embodiment of the utility model, a feeding device of a thread rolling machine for bolt production includes a body 1 of the thread rolling machine, a universal wheel is provided at the bottom of the body 1 for transporting the thread rolling machine, a feeding unit and a purification unit are provided at the top of the body 1, and the feeding unit includes a placement plate 2 and a storage box 3 fixedly provided at the top of the body 1;

[0025] Furthermore, a box cover is provided on the top of the storage box 3, a handle is provided on the top of the box cover, and an anti-slip pattern is provided on the inner side of the handle. The storage box 3 is fixedly connected to the top of the main body 1 through four support columns, a flexible pad is provided on the top of the placement plate 2, and the material discharged through the discharge pipe 4 is buffered by the flexible pad. An empty bin is provided at the bottom of the main body 1, and easily damaged parts of the main body 1 can be placed inside the empty bin for easy replacement at any time;

[0026] Furthermore, a discharge pipe 4 is provided at the bottom of the storage box 3, and the discharge pipe 4 is provided with a first opening 5 and a second opening 6. The top of the placement plate 2 is rotatably connected with a gear 7 and a rod 8, and a clamping block 9 is fixedly provided at one end of the rod 8. A vertical shaft 10 is fixedly provided at the top of the gear 7, and a first baffle 11 and a second baffle 12 are fixedly provided outside the vertical shaft 10. In the initial state, the clamping block 9 is located outside the gear 7 to position the gear 7 to prevent it from rotating arbitrarily. Since the first baffle 11 is located inside the first opening 5 in the initial state, the storage box 3 will enter the inside of the discharge pipe 4 and be located on the top of the first baffle 11;

[0027] It should be noted that a motor 13 is fixedly installed on the top of the main body 1, and the motor 13 is located at the bottom of the placement plate 2. The output end of the motor 13 is fixedly connected to a rotating shaft 14 that passes through the placement plate 2. A single-tooth column 15 is fixedly arranged on the outside of the rotating shaft 14, and a push rod 16 is fixedly arranged on the outside of the single-tooth column 15. Bristles 17 are arranged on the outside of the top of the rotating shaft 14. When feeding is required, the motor 13 is started to drive the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 drives the single-tooth column 15 and the push rod 16 to rotate. When the push rod 16 rotates, it will push the rod 8 to make it rotate. A reset spring is fixedly arranged on the top of the main body 1 One end of the reset spring is fixedly connected to the rod 8. When the push rod 16 is not in contact with the rod 8, the reset spring brings the rod 8 back to its original position. When the rod 8 rotates, the block 9 leaves the outside of the gear 7 to facilitate the subsequent rotation of the gear 7. When the single-tooth column 15 rotates, it drives the gear 7 to rotate. The above operation can realize the intermittent rotation of the gear 7. Then the gear 7 drives the first baffle 11 and the second baffle 12 to rotate intermittently through the vertical shaft 10. The purpose of the intermittent rotation is to make the first baffle 11 slowly leave the first opening 5, and then the material between the first opening 5 and the second opening 6 slowly falls from the discharge pipe 4.

[0028] Next, the purification unit includes a filter box 18 fixedly arranged on the top of the body 1, a through port 19 arranged on the top of the filter box 18, an exhaust port arranged on the back of the filter box 18, a spring 20 arranged on the top of the inner cavity of the filter box 18, a filter screen 21 arranged on the top of the spring 20, and the filter screen 21 is an activated carbon filter screen;

[0029] In addition, a hollow column 22 is fixedly provided inside the top of the filter box 18, a cylinder 23 is fixedly installed on the top of the hollow column 22, the output end of the cylinder 23 is located inside the hollow column 22 and a dual-purpose air pump 24 is fixedly provided, a hard rod 25 is fixedly provided at the bottom of the air pump 24, an air bag 26 that can be inflated after being inflated is provided on the outside of the hard rod 25, the air pump 24 is provided with an air pipe 27 and the end of the air pipe 27 is connected to the air bag 26, a circular opening 28 is provided at the bottom of the hollow column 22, a pressure block 29 is provided inside the hollow column 22, a slot 30 is provided at the center of the pressure block 29, the pressure block 29 hits the top of the filter screen 21, and the filter screen 21 is rebounded reciprocally under the action of the spring 20, and the waste debris blocking the filter screen 21 is ejected by the rebound action.

[0030] Working principle: open the box cover and put a batch of materials to be processed into the storage box 3. The bottom of the storage box 3 is tilted and the tilt angle is located at the position of the discharge pipe 4, which is conducive to the movement of the materials in the storage box 3 toward the discharge pipe 4 and into the inside of the discharge pipe 4. Since the first baffle 11 is located inside the first opening 5 in the initial state, the storage box 3 will enter the inside of the discharge pipe 4 and be located on the top of the first baffle 11. The first baffle 11 and the second baffle 12 are the same size and shape.

[0031] When feeding is needed, the motor 13 is started to drive the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 drives the single-tooth column 15 and the push rod 16 to rotate. When the push rod 16 rotates, it will push the rod 8 to make it rotate. A reset spring is fixedly provided on the top of the main body 1 and one end of the reset spring is fixedly connected to the rod 8. When the push rod 16 is not in contact with the rod 8, the reset spring brings the rod 8 to reset. When the rod 8 rotates, the block 9 leaves the outside of the gear 7 to facilitate the subsequent rotation of the gear 7. When the single-tooth column 15 rotates, it drives the gear 7 to rotate. The above operation can realize the intermittent rotation of the gear 7, and then the gear 7 drives the first baffle 11 and the second baffle 12 to rotate intermittently through the vertical shaft 10. The purpose of the intermittent rotation is to make the first baffle 11 slowly move from the second baffle 12 to the first baffle 11. The material between the first opening 5 and the second opening 6 slowly falls from the discharge pipe 4, which is beneficial to reducing the speed and frequency of material discharge. Because the thread rolling machine needs waiting time when working, it is necessary to control the speed and frequency of material discharge. After the first baffle 11 leaves the first opening 5, the second baffle 12 will enter the second opening 6, which is beneficial to block the discharge pipe 4 to prevent endless material discharge. The material can be transported to the main body 1 through the discharge mechanism to complete the feeding purpose. By placing a batch of materials into the storage box 3 and then using the discharge mechanism to automatically discharge the materials, the workload of the workers is reduced and the feeding efficiency is improved. The rotating shaft 14 can drive the brush 17 to rotate when rotating, and the brush 17 can clean the impurities on the material.

[0032] When the thread rolling machine is working, metal scrap particles will be generated, and these particles will be mixed with the air. An exhaust fan is installed on the back of the filter box 18. The suction nozzle of the exhaust fan is located at the bottom of the filter screen 21, which is used to draw air from the position of the opening 19 into the filter box 18. The air entering the filter box 18 will pass through the filter screen 21 to filter the metal scraps in the air, which is conducive to filtering the air and preventing workers from inhaling air with metal scraps.

[0033] However, the filter screen 21 may be clogged after being used for a period of time. The solution is as follows: the air cylinder 23 drives the air pump 24 to descend. When the air pump 24 descends, the hard rod 25 and the air bag 26 enter the interior of the slot 30. At this time, the air pump 24 discharges air into the interior of the air bag 26 through the air pipe 27, and then the air bag 26 expands to fill the slot 30 to complete the connection between the hard rod 25 and the pressing block 29. Since the slot 30 is filled, when the air pump 24 rises, it will drive the pressing block 29 to rise, and the pressing block 29 begins to Finally, it rises and falls in the circular opening 28, and then the air pump 24 draws out the air in the airbag 26. At this time, the airbag 26 shrinks and then the pressing block 29 falls in the circular opening 28 and hits the filter screen 21. Under the action of the spring 20, the filter screen 21 rebounds back and forth, and the waste debris blocking the filter screen 21 is ejected through the rebound action. A vacuum cleaner is installed on the side of the filter box 18. The vacuum cleaner is provided with a forked straw, which is located at the top and bottom of the filter screen 21. When the waste debris is ejected, the forked straw sucks the waste debris.
