The end of the sleeve rod away from the sleeve is fixedly connected to the support plate. A slider is slidably connected to the inner side of the sleeve, and one side of the slider is fixedly connected to the sleeve rod.

[0009] Preferably, the elastic connecting member further includes a spring. The spring is sleeved on the inner side of the sleeve. One end of the spring abuts against the slider, and the other end of the spring abuts against the inner wall of the sleeve.

[0010] Preferably, the driving mechanism includes a motor. The motor is fixedly installed on the outer side of the thread rolling machine body. The output shaft of the motor is fixedly connected to a first belt pulley. One end of the first rotating shaft is fixedly connected to a second belt pulley.

[0014] The working principle and beneficial effects of the present utility model are as follows:

[0015] 1. The driving mechanism can drive the first rotating shaft to rotate, which makes the first rotating rod rotate synchronously, so that all the elastic connecting members drive the corresponding support plates to rotate circumferentially. When one of the support plates abuts against the screw, sliding friction occurs between the support plate and the screw, which makes the screw slide outward under the action of the frictional force. When the next support plate abuts against the screw, the screw slides outward again. In this way, the screw can be drawn out under the repeated action of different support plates to achieve blanking. The whole process does not require complex operations, can realize the automatic blanking of the screw, and greatly improves the processing efficiency of the screw;

[0016] 2. When the screw is withdrawn, it will fall onto the material receiving seat. The incomplete gear is driven to rotate by the motor. When the incomplete gear meshes with the gear, the gear will drive the worm to rotate, which causes the worm wheel to drive the second rotating shaft to rotate, and then causes the second rotating rod to rotate. As a result, the material receiving seat rotates with the second rotating rod and transfers the screw into the storage box. This process can achieve catching and transferring the withdrawn screw, and the whole process does not require manual participation, greatly improving the processing efficiency of the screw.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0026] As Figures 1 to 6As shown in the figure, this embodiment proposes a material receiving device for a thread rolling machine, which includes a thread rolling machine body 1. A blanking mechanism 3 is arranged on one side of the thread rolling machine body 1. The blanking mechanism 3 includes a mounting base 31. The mounting base 31 is fixedly connected to one side of the thread rolling machine body 1. A first rotating shaft 32 is rotatably connected to the inner side of the mounting base 31. A first roller 33 is fixedly connected to the middle of the first rotating shaft 32. A number of elastic connecting pieces 34 are fixedly connected to the outer side of the first roller 33. One end of each of the number of elastic connecting pieces 34 is fixedly connected to a support plate 35. The support plate 35 can rotate through the first roller 33 and abut against the screw 2. The support plate 35 is of an arc structure, and the diameter of the support plate 35 is larger than the diameter of the screw 2. A driving mechanism 4 for driving the first rotating shaft 32 to rotate is arranged at the bottom of the thread rolling machine body 1. A material receiving mechanism 5 for receiving the screw 2 is arranged below the first roller 33. A transmission mechanism 6 for driving the material receiving mechanism 5 to rotate intermittently by the drive of the driving mechanism 4 is arranged on one side of the material receiving mechanism 5.

[0027] The driving mechanism 4 can drive the first rotating shaft 32 to rotate, which makes the first roller 33 rotate synchronously, so that all the elastic connecting pieces 34 drive the corresponding support plates 35 to rotate circumferentially. When one of the support plates 35 abuts against the screw 2, sliding friction occurs between the support plate 35 and the screw 2, which makes the screw 2 slide outwards under the action of the frictional force. When the next support plate 35 abuts against the screw 2, the screw 2 slides outwards again. In this way, the screw 2 can be drawn out under the repeated action of different support plates 35 to achieve blanking. The whole process does not require complex operations, and the automatic blanking of the screw 2 can be realized, which greatly improves the processing efficiency of the screw 2.

[0028] Further, the elastic connecting piece 34 includes a sleeve 341. One end of the sleeve 341 is fixedly connected to the first roller 33. The other end of the sleeve 341 is slidably connected with a sleeve rod 342. The end of the sleeve rod 342 away from the sleeve 341 is fixedly connected to the support plate 35. A slider 343 is slidably connected to the inner side of the sleeve 341. One side of the slider 343 is fixedly connected to the sleeve rod 342. A spring 344 is sleeved on the inner side of the sleeve 341. One end of the spring 344 abuts against the slider 343, and the other end of the spring 344 abuts against the inner wall of the sleeve 341.

[0029] The elastic performance of the spring 344 itself can make the support plate 35 and the screw 2 in elastic contact, which can avoid the problem of jamming caused by excessive frictional force between the support plate 35 and the screw 2.

[0030] Further, the driving mechanism 4 includes a motor 41 fixedly installed outside the thread rolling machine body 1. One end of the output shaft of the motor 41 is fixedly connected with a first belt pulley 42. One end of the first rotating shaft 32 is fixedly connected with a second belt pulley 43. The second belt pulley 43 is connected to the first belt pulley 42 through belt transmission. By starting the motor 41 to drive the first belt pulley 42 to rotate, the second belt pulley 43 rotates synchronously under the transmission of the belt, which causes the first rotating shaft 32 to rotate, and then the first roller 33 drives the support plate 35 to rotate circumferentially, so that the support plate 35 pulls out the screw rod 2.

[0031] Further, the material receiving mechanism 5 includes a second rotating shaft 51 rotatably connected outside the thread rolling machine body 1. The middle part of the second rotating shaft 51 is fixedly connected with a second roller 52. A plurality of material receiving seats 53 are fixedly connected to the outside of the second roller 52 and are evenly distributed around the second roller 52 at equal angles. A storage box 7 for storing the screw rod 2 is arranged below the second roller 52. The storage box 7 is fixedly connected to the outside of the thread rolling machine body 1. The transmission mechanism 6 includes a worm gear 61 fixedly connected to the middle part of the second rotating shaft 51. A worm 62 meshing with the worm gear 61 is rotatably connected to the outside of the thread rolling machine body 1. One end of the worm 62 is fixedly connected with a gear 63. The output shaft of the motor 41 is also fixedly connected with an incomplete gear 64. The incomplete gear 64 intermittently meshes with the gear 63.

[0032] When the screw rod 2 is pulled out, it will fall onto the material receiving seat 53. By driving the incomplete gear 64 to rotate through the motor 41, when the incomplete gear 64 meshes with the gear 63, the gear 63 will drive the worm 62 to rotate, which causes the worm gear 61 to drive the second rotating shaft 51 to rotate, and then the second roller 52 rotates, so that the material receiving seat 53 rotates with the second roller 52 and transfers the screw rod 2 into the storage box 7. This process can catch and transfer the pulled-out screw rod 2, and the whole process does not require manual participation, greatly improving the processing efficiency of the screw rod 2.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
