[0002] Screws, also known as screws, are a common fastener that is widely used in machinery, electrical appliances and construction industries. They are generally made of metal or plastic and are cylindrical. They are fixed to other objects through the threads on their surface.

Under the action of the smooth connection between the elastic bands 64 and the U-shaped conveying frame 311, the screws can slide to the surface of the elastic bands 64, and the elastic bands 64 have appropriate elasticity, so that the screws can avoid hindering the rotation of the U-shaped conveying frame 311 when sliding onto the elastic bands 64.

[0031] The present invention provides a screw thread rolling device through improvement, and its working principle is as follows; First, when using the device, first place the device in the working area, and then connect the device to an external power supply to provide the device with the power required for work, so that the screws to be threaded are placed inside the box 2, and under the action of the second guide hopper 314, the screws are accumulated at a position close to the conveying disc 35, and the driving motor 32 is started by the controller. The operation of the driving motor 32 drives the first rotating shaft 33 to rotate, and then drives the conveying disc 35 to rotate. During the rotation, the conveying disc 35 drives the semi-arc scraper 36 in a circular array to rotate synchronously, so that the screws on the second guide hopper 314 are shoveled to the inside of the semi-arc scraper 36, and as the conveying disc 35 rotates, the semi-arc ring 37 is set to facilitate shoveling more screws and prevent the shoveled screws from falling. After the semi-arc scraper 36 rotates to an appropriate height, that is, when the inclination angle of the semi-arc scraper 36 is appropriate, the screws inside the semi-arc scraper 36 will slide along the inside of the semi-arc scraper 36 to the inside of the first guide hopper 38. The first guide hopper 38 The first guide hopper 38 is arranged obliquely, and the first guide hopper 38 is located directly above the U-shaped conveying frame 311. After the screw falls on the first guide hopper 38, it slides along the inside of the first guide hopper 38 and falls on the U-shaped conveying frame 311. During the downward movement of the screw, the screw will randomly fall on the U-shaped conveying frame 311, and the end of the screw will fit the surface of the U-shaped conveying frame 311. The rod of the screw is located inside the U-shaped conveying frame 311. If the position where the screw falls is just right, it can be stuck on the U-shaped conveying frame 311 and fail to fall. The screws on the U-shaped conveyor frame 311 slide along the surface of the second guide hopper 314 and fall to a position close to the conveying disc 35, so as to repeat the above process. The conveying disc 35 drives the semi-arc scraper 36 to rotate by the operation of the driving motor 32, so as to scoop up the screws inside the box body 2. After the semi-arc scraper 36 rotates to a suitable angle with the conveying disc 35, the screws fall into the first guide hopper 38. Under the guidance of the first guide hopper 38, the screws fall into the U-shaped conveyor frame 311. Second, the operation of the driving motor 32 drives the conveying disc 35 to rotate through the first rotating shaft 33. The rotation of the first rotating shaft 33 drives the dial plate 49 to rotate synchronously. When the dial plate 49 rotates to fit the inner wall of the rectangular frame 47, a force is applied to the rectangular frame 47, so that the rectangular frame 47 moves upward. The movement of the rectangular frame 47 drives the tooth plate 45 to fit the inner wall of the L-shaped block 46 and slide. The movement of the tooth plate 45 drives the gear 44 meshing with it to rotate, and then drives the second rotating shaft 41 to rotate. When the dial plate 49 rotates When the second rotating shaft 41 is in a vertically upward state, the second rotating shaft 41 rotates a certain angle. When the dial plate 49 continues to rotate with the first rotating shaft 33, the rectangular frame 47 moves downward under the action of the gravity of the counterweight 48, causing the second rotating shaft 41 to rotate in the opposite direction until the rectangular frame 47 fits the surface of the first rotating shaft 33. At this time, the second rotating shaft 41 stops rotating. The rotation of the second rotating shaft 41 drives the connecting plate 42 to rotate, thereby causing the connecting plate 42 to intermittently swing at a certain angle. The rotation of 42 drives the brush plate 43 to rotate synchronously. During the intermittent swinging of the brush plate 43, when the brush portion of the brush plate 43 moves to the position of the U-shaped conveying frame 311, it can fit with the upper surface of the U-shaped conveying frame 311. During the up and down movement of the screw, the position where the screw falls is just right, and it can be stuck on the U-shaped conveying frame 311. The screw that falls on the U-shaped conveying frame 311 but is not stuck inside the U-shaped conveying frame 311 can be stuck to the U-shaped conveying frame 311 during the rotation of the brush plate 43. The screws brushed off slide along the surface of the second guide hopper 314 and slide to a position close to the conveying disc 35, and the above process is repeated, which is conducive to making the screws that have not fallen on the U-shaped conveying frame 311 slide along the surface of the second guide hopper 314 and slide to a position close to the conveying disc 35. During the intermittent rotation of the brush plate 43, the screws that are not stuck on the U-shaped conveying frame 311 are brushed off, so as to avoid the situation that the screws cannot be orderly placed in the U-shaped conveying frame 311 for transportation and affect the subsequent thread rolling process. Third, during the intermittent rotation of the second rotating shaft 41, the rotation of the second rotating shaft 41 drives the rotating disk 55 to rotate synchronously, and the rotation of the rotating disk 55 drives the isosceles triangle block 56 to rotate synchronously. Under the action of the inclination of both sides of the isosceles triangle block 56, the triangular cone plate 53 can be lifted up, and the triangular cone plate 53 moves downward after being lifted up. During the vertical movement of the triangular cone plate 53, the top plate 54 is driven to move synchronously, and then the U-shaped conveying frame 311 is driven to reciprocate and shake around the rotating pin 313 as the axis through the side rod 52. The reciprocating shaking of the U-shaped conveying frame 311 can make the screws inside the U-shaped conveying frame 311 move in the U-shaped conveying frame The screws in the box body 2 are transported to the inside of the U-shaped transport frame 311, and the screws in the U-shaped transport frame 311 can be moved toward the direction of the first wash plate 61 due to the tilting of the U-shaped transport frame 311. Since the second rotating shaft 41 rotates intermittently, the rotating disk 55 drives the isosceles triangle block 56 to rotate intermittently, so that the U-shaped transport frame 311 intermittently shakes, so that the screws in the U-shaped transport frame 311 are transported and the screws in the box body 2 are inserted into the inside of the U-shaped transport frame 311, thereby avoiding the situation where the screws are inserted into the inside of the U-shaped transport frame 311 with a low accuracy due to the continuous shaking of the U-shaped transport frame 311. Fourth, when the screw slides along the inside of the U-shaped conveyor frame 311 to a position close to the first rubbing plate 61, the screw can slide to the surface of the elastic belt 64 under the action of the smooth connection between the elastic belt 64 and the U-shaped conveyor frame 311, and the elastic belt 64 has appropriate elasticity, so that the screw avoids hindering the rotation of the U-shaped conveyor frame 311 when sliding on the elastic belt 64. The screw slides between the two elastic belts 64 to the inside of the discharge chute 65 and slides to fit the surface of the second rubbing plate 62. At this time, the electric hydraulic push rod 66 is started, and the operation of the electric hydraulic push rod 66 drives the second rubbing plate 62 to slide along the surface of the transverse guide rail 63. Under the action of the first rubbing plate 61 and the second rubbing plate 62, the thread rolling process can be realized for the screw that fits the surface of the second rubbing plate 62. In the process of moving the second rubbing plate 62, the elastic potential energy of the spring 610 can make the square plate 611 fit the second rubbing plate 62 and move a distance. The movement of the square plate 611 drives the triangular plate 612 to move synchronously. The triangular plate 612 During the movement, the screws attached to the surface of the second rubbing plate 62 can be pushed to move while blocking the material trough 65 to prevent the screws inside the material trough 65 from slipping out of the material trough 65. After the thread rolling is completed, the second rubbing plate 62 moves toward the mounting plate 67 to reset. When the surfaces of the second rubbing plate 62 and the square plate 611 are attached, the second rubbing plate 62 drives the square plate 611 to move toward the fixing plate 68, thereby moving the triangular plate 612 away from the position of the material trough 65, and the U-shaped seat 3 12 Under the thrust of the internal screw, the screw inside the feed chute 65 moves to fit with the surface of the second rubbing plate 62, and the above process is repeated to roll another screw again. This is beneficial for rolling the screw that fits the surface of the second rubbing plate 62. The triangular plate 612 pushes the screw that fits the surface of the second rubbing plate 62 to move while blocking the feed chute 65, so as to prevent the screw inside the feed chute 65 from slipping out of the feed chute 65 and affecting the screw rolling effect when the previous screw is not rolled.
