Description

Technical Field

[0001] This application relates to the field of screw processing equipment technology, specifically a waste separation mechanism for a screw thread rolling machine. Background Technology

[0002] In the screw manufacturing process, thread rolling is a crucial step. A thread rolling machine uses a specific mold to extrude and shape the screw blank, forming the desired thread shape at its head. However, to ensure the integrity and quality of the screw thread, one end of the screw blank is usually cut to remove excess material; this removed material is called head-cutting waste. Therefore, after the thread rolling process is completed, a large number of thread-rolled screws and head-cutting waste are generated simultaneously.

[0003] However, in practical applications, traditional screening methods have many drawbacks, resulting in low separation efficiency and poor results. In particular, during the thread rolling process, the screw end has a specific groove structure, and the cut-off part, due to its shape and material characteristics, can easily get stuck in the groove at the screw end. This causes the interlocking screw and cut-off part to move as a whole, making it difficult to separate them effectively in the expected way. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a waste separation mechanism for screw thread rolling machines, which has advantages such as improving the separation efficiency of screws and cut head waste, and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a waste separation mechanism for a screw thread rolling machine, comprising a base, a screening cylinder above the base, a separation groove on the outer surface of the middle part of the screening cylinder, a ring gear fixedly connected to the outer surface of the screening cylinder, a mounting base fixedly connected to the upper surface of the base, a servo motor fixedly mounted on the inner side of the mounting base, a transmission gear fixedly connected to the output end of the servo motor, the transmission gear meshing with the ring gear, two semi-circular baffles fixedly connected to the inner wall of the screening cylinder, the two semi-circular baffles being symmetrically and staggered, and a collection box placed on the inner wall of the base.

[0006] The above scheme, through the interaction of the ring gear, servo motor, and transmission gear, enables the screening cylinder to rotate stably, thereby separating the screws and cut-off waste materials fed into the screening cylinder. Furthermore, the two symmetrically and staggeredly placed semi-circular baffles reduce the flow speed of the screws and cut-off materials, allowing the cut-off materials more time and opportunity to fall through the separation groove. At the same time, the rotating screening cylinder, in conjunction with the semi-circular baffles, helps to break the jamming state between the cut-off materials and the screw end grooves, greatly improving the separation efficiency of the cut-off waste materials and ensuring the stability of product quality.

[0007] Furthermore, two fixing rings are fixedly connected to the outer surface of the screening cylinder, and a support base is fixedly connected to the upper surface of the base. The outer surfaces of the two fixing rings are slidably connected to the inner wall of the support base.

[0008] Through the above scheme, the support base can provide stable support for the screening cylinder, and the fixed ring can make the screening cylinder rotate stably, ensuring the separation of materials.

[0009] Furthermore, wear-resistant pads are fixedly connected to both outer sides of the screening cylinder, and two symmetrical first supports are fixedly connected to the upper surface of the base. A first abutting wheel is rotatably installed on one side of each of the two first supports, and the outer surfaces of the two first abutting wheels are in contact with the outer surface of one of the wear-resistant pads. Two symmetrical second supports are fixedly connected to the upper surface of the base, and a second abutting wheel is rotatably installed on one side of each of the two second supports, and the outer surfaces of the two second abutting wheels are in contact with the outer surface of the other wear-resistant pad.

[0010] Through the above scheme, the cooperation between the wear-resistant pad, the first support, the first abutting wheel, the second support, and the second abutting wheel can provide auxiliary support for the screening cylinder, thereby ensuring stable support of the screening cylinder. Furthermore, the first abutting wheel and the second abutting wheel can reduce the pressure on the screening cylinder, thereby allowing the screening cylinder to rotate stably and ensuring that the screening cylinder can rotate stably to separate the materials.

[0011] Furthermore, a processing table is fixedly installed on one side of the base, a mounting frame is fixedly installed on the upper surface of the processing table, a fixed thread rolling plate is fixedly connected to one side of the mounting frame, a guide rail is fixedly connected to the upper surface of the base, and a sliding plate is slidably arranged on the inner wall of the guide rail.

[0012] The above solution, through the interaction between the fixed thread rolling plate and the sliding plate, enables the thread rolling process of the conveyed screws, thereby improving the efficiency of screw processing.

[0013] Furthermore, a drive motor is provided above the processing table. The drive motor is fixedly installed on the upper surface of the processing table by a bracket. A turntable is fixedly connected to the output end of the drive motor, and a fixing column is fixedly connected to the outer surface of the turntable.

[0014] With the above solution, the drive motor is stably fixed on the processing table by the bracket, thereby ensuring that the drive motor can drive the turntable to rotate stably.

[0015] Furthermore, a connecting rod is rotatably connected to the outer surface of the fixed column, and one end of the connecting rod away from the outer surface of the fixed column is hinged to the inner wall of the sliding plate.

[0016] With the above solution, the fixed column moves in a circular motion driven by the turntable, and the sliding plate can stably perform thread rolling on the screws under the drive of the connecting rod, thus improving the practicality of the device.

[0017] Furthermore, a vibratory feeder is installed on the outer surface of the processing table, and a conveying track is fixedly installed on the outer surface of the vibratory feeder. The end of the conveying track away from the vibratory feeder is fixedly connected to the outer surface of the fixed tooth rolling plate.

[0018] The above scheme, through the use of a vibratory feeder and conveyor track, allows screws to be properly arranged and stably conveyed into a fixed thread rolling plate. This enables accurate screw processing, reduces thread processing errors caused by irregular screw posture, and improves the processing accuracy and quality of screws.

[0019] Furthermore, a guide plate is fixedly connected to the outer surface of the processing table.

[0020] The above solution, by setting up a guide plate, can guide the screws in the thread-rubbing process, allowing them to fall stably into the screening cylinder for separation, thereby improving production efficiency.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This screw thread rolling machine waste separation mechanism, through the interaction of a ring gear, servo motor, and transmission gear, can stably rotate the screening cylinder, thereby separating the screws and cut head waste materials conveyed into the screening cylinder. Furthermore, two symmetrically and staggeredly placed semi-circular baffles can reduce the flow speed of screws and cut heads, allowing the cut heads more time and opportunity to fall through the separation groove. At the same time, the rotating screening cylinder, in conjunction with the semi-circular baffles, helps to break the jamming state between the cut heads and the screw end grooves, greatly improving the separation efficiency of cut head waste materials and ensuring the stability of product quality.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 4 and Figure 5This embodiment of a screw thread rolling machine waste separation mechanism includes a base 1, with a screening cylinder 2 positioned above the base 1. The screening cylinder 2 is inclined, allowing the screws inside to be discharged from the lower opening of the screening cylinder 2 under their own weight. A separation groove 3 is formed on the outer surface of the middle part of the screening cylinder 2, and the groove opening of the separation groove 3 allows the cut-off head to be discharged and the retained screws to be efficiently separated after thread rolling. A ring gear 4 is fixedly connected to the outer surface of the screening cylinder 2, and a mounting base 5 is fixedly connected to the upper surface of the base 1. The mounting base 5 supports a servo motor 6, thereby ensuring that the transmission gear 7 is stably meshed with the ring gear 4. The servo motor 6 is fixedly mounted on the inner side of the mounting base 5, and the output end of the servo motor 6 is fixedly connected to the transmission gear 7. The transmission gear 7 and the ring gear are... The four-phase meshing system consists of two semi-circular baffles 8 fixedly connected to the inner wall of the screening cylinder 2. Through the action of the ring gear 4, servo motor 6, and transmission gear 7, the screening cylinder 2 can rotate stably, thereby separating the screws and cut-off waste materials fed into the screening cylinder 2. The two symmetrically and staggeredly placed semi-circular baffles 8 reduce the flow speed of the screws and cut-off materials, allowing the cut-off materials more time and opportunity to fall through the separation groove 3. At the same time, the rotating screening cylinder 2, in conjunction with the semi-circular baffles 8, helps to break the jamming state between the cut-off materials and the screw end grooves, greatly improving the separation efficiency of the cut-off waste materials and ensuring the stability of product quality. The two semi-circular baffles 8 are symmetrically and staggeredly placed. A collection box 9 is placed on the inner wall of the base 1. The collection box 9 can collect the separated screws, making it convenient for personnel to handle.

[0032] Please see Figure 1 , Figure 2 and Figure 4Two fixing rings 10 are fixedly connected to the outer surface of the screening cylinder 2, and a support base 11 is fixedly connected to the upper surface of the base 1. The outer surfaces of the two fixing rings 10 are slidably connected to the inner wall of the support base 11. The support base 11 provides stable support for the screening cylinder 2 and allows the screening cylinder 2 to rotate stably under the action of the fixing rings 10, ensuring the separation of materials. Wear-resistant pads 12 are fixedly connected to the outer surfaces of both ends of the screening cylinder 2. Two symmetrical first supports 13 are fixedly connected to the upper surface of the base 1. A first abutment wheel 14 is rotatably mounted on one side of each of the two first supports 13. The outer surfaces of the two first abutment wheels 14 are in contact with the outer surface of one of the wear-resistant pads 12. The upper surface of the base 1 is fixedly connected to two symmetrical second supports 15. Each of the two second supports 15 has a second abutment wheel 16 rotatably mounted on one side. The outer surfaces of the two second abutment wheels 16 are in contact with the outer surface of another wear-resistant pad 12. The cooperation between the wear-resistant pad 12, the first support 13, the first abutment wheel 14, the second support 15, and the second abutment wheel 16 can provide auxiliary support for the screening cylinder 2, thereby ensuring the stable support of the screening cylinder 2. Furthermore, the action of the first abutment wheel 14 and the second abutment wheel 16 can reduce the pressure on the screening cylinder 2, thereby allowing the screening cylinder 2 to rotate stably and ensuring that the screening cylinder 2 can rotate stably to separate the material.

[0033] Please see Figure 1 , Figure 2 and Figure 3A processing table 17 is fixedly mounted on one side of the base 1. A mounting bracket 18 is fixedly mounted on the upper surface of the processing table 17. A fixed thread rolling plate 19 is fixedly connected to one side of the mounting bracket 18. A guide rail 20 is fixedly connected to the upper surface of the base 1. A sliding plate 21 is slidably arranged on the inner wall of the guide rail 20. Through the action of the fixed thread rolling plate 19 and the sliding plate 21, the screws being fed can be thread rolled, improving the efficiency of screw processing. A drive motor 22 is provided above the processing table 17. The drive motor 22 is fixedly mounted on the upper surface of the processing table 17 by a bracket. A turntable 23 is fixedly connected to the output end of the drive motor 22. A fixed column 24 is fixedly connected to the outer surface of the turntable 23. The drive motor 22 is stably fixed on the processing table 17 by the bracket, thereby ensuring that the drive motor 22 can drive the turntable 23 to rotate stably. A connecting rod 25 is rotatably connected to the outer surface of the fixed column 24. The end of the connecting rod 25 away from the outer surface of the fixed column 24 is hinged. On the inner wall of the sliding plate 21, the aforementioned fixed column 24 moves in a circular motion under the drive of the turntable 23. Driven by the connecting rod 25, it can stably drive the sliding plate 21 to perform thread rolling on the screws, improving the practicality of the device. A vibratory plate 26 is installed on the outer surface of the processing table 17, and a conveying track 27 is fixedly installed on the outer surface of the vibratory plate 26. The end of the conveying track 27 away from the vibratory plate 26 is fixedly connected to the outer surface of the fixed thread rolling plate 19. Through the function of the vibratory plate 26 and the conveying track 27, the screws can be sorted and stably conveyed into the fixed thread rolling plate 19, thereby accurately processing the screws, reducing thread processing errors caused by irregular screw posture, and improving the processing accuracy and quality of the screws. A guide plate 28 is fixedly connected to the outer surface of the processing table 17. Through the function of the guide plate 28, the thread-rolling screws can be guided and stably fall into the interior of the screening cylinder 2 for separation, thereby improving production efficiency.

[0034] In this embodiment, a waste separation mechanism for a screw thread rolling machine, through the interaction of a ring gear 4, a servo motor 6, and a transmission gear 7, can stably rotate the screening cylinder 2, thereby separating the screws and cut-off waste materials fed into the screening cylinder 2. Furthermore, two symmetrically and staggeredly placed semi-circular baffles 8 can reduce the flow speed of the screws and cut-off materials, allowing the cut-off materials more time and opportunity to fall through the separation groove 3. At the same time, the rotating screening cylinder 2, in conjunction with the semi-circular baffles 8, helps to break the jamming state between the cut-off materials and the screw end grooves, greatly improving the separation efficiency of the cut-off waste materials and ensuring the stability of product quality.

[0035] The working principle of the above embodiment is as follows: First, the screws inside the vibratory plate 26, after being tidied by it, can be stably conveyed to the fixed thread-rubbing plate 19 under the conveying rail 27. Then, the drive motor 22 can drive the turntable 23 to rotate and drive the fixed column 24 to perform circumferential motion. At this time, under the transmission of the connecting rod 25, the sliding plate 21 can slide on the inner wall of the guide rail 20. At this time, the sliding plate 21, in conjunction with the fixed thread-rubbing plate 19, can rub the screws. Then, the rubbed screws and the cut waste are guided by the guide plate 28 and conveyed to the inside of the screening cylinder 2. Subsequently, the servo motor 6 drives the transmission gear 7 to rotate, and the meshing with the ring gear 4 stably drives the screening cylinder 2 to rotate, so that the bolts inside the screening cylinder 2 are in a continuous state of motion. This helps to break the jamming state between the cut head and the screw end slot. In addition, the two symmetrical and staggered semi-circular baffles 8 further reduce the flow speed of the screw and the cut head, allowing the cut head more time and opportunity to fall through the separation groove 3, thereby improving the separation effect of screw and cut head waste. After that, the separated finished screws fall into the collection box 9 for centralized collection.
