Description

TECHNICAL FIELD

[0001] The present application relates to the field of waste separation devices, in particular to a screw thread rolling machine waste separation device. BACKGROUND

[0002] The production process of a screw generally includes cold upsetting, punch, thread rolling and the like. Thread rolling is a process of manufacturing threads at the screw shaft, which is generally completed by a screw thread rolling machine. During the screw thread rolling process, the tolerance of the moving block of the machine is prone to be too large, which leads to unstable feeding and mismatching between the feeding speed and the thread rolling speed, thereby causing the screw head after thread rolling to be damaged, deformed or even broken. The screws with the above conditions are defined as defective screws because they do not meet the sales specifications. In order to reduce the defective rate of the sales screws, it is generally necessary to screen the screws after thread rolling by means of manual or machine, to obtain defective screws and good screws, and then to sell the good screws to ensure the sales quality.

[0003] Currently, an automatic screening method is used to screen the screws after thread rolling. A rack and two driving conveying units are provided. Each driving conveying unit includes a screw conveying member and a driving member for driving the screw conveying member. The two driving members drive the two screw conveying members to form a screw screening gap between them, thereby completing the screening of good screws and defective screws.

[0004] However, in actual production, since two driving members need to be driven at the same time to realize the precise cooperation of the two drivable screw conveying members and the screw screening function, the energy consumption is high, which increases the cost of screw production and manufacturing. In particular, in the continuous production process, long-time operation will significantly increase energy consumption, which is not conducive to the economic benefits and sustainable development of enterprises. CONTENT OF THE INVENTION

[0005] In order to reduce the energy consumption and production cost of screw production, the present application provides a screw thread rolling machine waste separation device.

[0006] To achieve the above purpose, the present application provides a screw thread rolling machine waste separation device, which comprises a rack and a screening mechanism arranged in the rack. The screening mechanism comprises a driving conveying unit and a screw guide. The screw guide is stationary relative to the rack. The driving unit comprises a screw conveying member for conveying screws and a driving member for driving the screw conveying member. A screw screening gap is provided between the screw conveying member and the screw guide. The driving member and the screw guide are both mounted on the rack.

[0007] By adopting the above technical solution, a single drive unit drives the screw conveyor, which, in conjunction with the screw guide, forms a screening gap. Based on a pre-set screw screening gap according to the screw head size, when a threaded screw falls into the screening gap, screws that do not completely pass through are considered good screws. The drive unit then drives the screw conveyor to transport these good screws to the good screw collection area. Screws that completely pass through the screening gap are considered defective screws and enter the defective screw collection area after passing through the gap. This process achieves the screening of threaded screws. In this process, only one drive unit is needed to drive the screw conveyor, working in conjunction with the screw guide to screen the threaded screws. Compared to simultaneously driving two drive units to drive two separate screw conveyors for screw screening, this method has the advantages of low energy consumption and low production cost.

[0008] Preferably, the screw screening gap has a spacing of a, the screw shaft diameter of b, and the screw head diameter of c. The screw screening gap satisfies the following condition b. <a<c。

[0009] By adopting the above technical solution, it is possible to ensure that the spacing of the screw screening gap is adapted to the case where the head diameter of the good screw is larger than the shaft diameter of the screw. This allows the good screw to be smoothly stuck in the screening gap during the conveying process, while the defective screw, due to its smaller head diameter, cannot be stuck and falls to the defective product collection point. This effectively improves screening efficiency and accuracy and reduces the defective product rate.

[0010] Preferably, the drive transmission unit further includes a connecting seat, the drive component is disposed on the connecting seat, and the connecting seat is mounted on the frame.

[0011] By adopting the above technical solution, the connector allows the drive component to be mounted more stably on the frame, ensuring the reliability and stability of the drive component's operation. At the same time, the connector design facilitates the maintenance and replacement of the drive component, improving the maintainability of the device.

[0012] Preferably, the connecting seat is further provided with an adjusting member for controlling the movement of the screw guide.

[0013] Based on reducing energy consumption and production costs in screw production, this application utilizes an adjusting component to effectively control the movement of the screw guide component, thereby adjusting the size of the screw screening gap. This facilitates the screening of screws of different specifications, further improving production efficiency and reducing production costs. At the same time, it also enables strict control over the quality of the screened screws.

[0014] Specifically, the adjusting mechanism on the connecting seat effectively controls the movement of the screw guide, ensuring that the screw screening gap is always maintained at its optimal state. This not only improves the accuracy of screw screening but also adapts to the production needs of screws of different specifications, avoiding product quality problems caused by improper equipment adjustment. Furthermore, the adjusting mechanism's design simplifies operation and reduces equipment maintenance costs and time.

[0015] Preferably, the adjusting component includes a sliding block and a bolt. The connecting seat has a sliding groove on the side near the screw guide and a through hole on the side away from the screw guide, and the through hole communicates with the sliding groove. The sliding block is slidably disposed in the sliding groove. The bolt passes through the through hole and is screwed to the sliding block. The sliding direction of the sliding block is perpendicular to the conveying direction of the screw conveyor. The sliding block is connected to the screw guide.

[0016] By adopting the above technical solution, the adjusting component allows for flexible adjustment of the position of the screw guide. Specifically, the sliding block can slide within the sliding groove in a direction perpendicular to the screw conveyor, thereby changing the size of the screw screening gap to accommodate screws of different specifications. When the bolt passes through the through hole and is screwed onto the sliding block, the position of the sliding block can be locked. This design not only improves the applicability of the equipment but also effectively reduces the debugging time caused by changes in screw specifications, improves production efficiency, and reduces production costs.

[0017] Preferably, the screw conveyor is a conveying screw, and the driving component drives the conveying screw.

[0018] By adopting the above technical solution, a transmission screw is used as the screw transmission component. The thread of the transmission screw has a certain friction force, which can prevent the screw from slipping on the transmission screw. When the driving component drives the transmission screw, the transmission screw drives the screw to move, realizing the efficient transmission of the screw.

[0019] Preferably, the screw transmission component is a steel wire rope, and the steel wire rope is connected to a driving component that drives the steel wire rope.

[0020] By adopting the above technical solution, the surface of the steel wire rope is rough, and a certain friction is formed between the steel wire rope and the coil, which can prevent the screw from slipping on the steel wire rope. When the driving component drives the steel wire rope, the steel wire rope drives the screw to move, thereby realizing the efficient transmission of the steel wire rope.

[0021] Preferably, the conveying direction of the screw conveyor forms an angle of less than 90° with the horizontal plane of the frame.

[0022] By adopting the above technical solution, the force exerted by the screws on the defective product collection point during the conveying process is increased, making them fall more accurately into the screening gap and improving the screening accuracy.

[0023] Preferably, the screening mechanism further includes a collection component located at the feed end of the screw screening gap. The guiding component includes a second guiding component and two first guiding components. The two first guiding components are respectively fixed to the inner walls on both sides of the frame. Each first guiding component forms an angle of less than 90° with the side wall of the frame toward the screw guide component. The second guiding component is installed on the frame and is located between the two first guiding components.

[0024] By adopting the above technical solution, the arrangement of two first and second guide components ensures that the screw is smoothly guided along a predetermined path before entering the screening gap, reducing jamming or misalignment caused by positional deviations and improving screening accuracy. Simultaneously, the angle design between the first guide component and the side wall of the frame helps guide the screw into the screening gap in the correct direction, further enhancing the equipment's working efficiency and reliability.

[0025] Preferably, the screening mechanism further includes a collection component located at the discharge end of the screw screening gap. The collection component includes: a defective product guide plate, a defective product collection box, a good product guide plate, and a good product collection box. Screws that completely pass through the screw screening gap enter the feed end of the defective product guide plate, while screws that do not completely pass through the screw screening gap are conveyed to the feed end of the good product guide plate. The discharge end of the defective product guide plate is connected to the feed end of the defective product collection box, and the discharge end of the good product guide plate is connected to the feed end of the good product collection box.

[0026] By adopting the above technical solution, the waste separation device for the screw rolling machine can effectively distinguish between good and defective screws. Specifically, when the screws after rolling pass through the screw screening gap, screws that do not completely pass through the gap are conveyed to the good product guide plate and eventually enter the good product collection box for collection; while screws that completely pass through the gap fall into the defective product guide plate and are eventually collected in the defective product collection box. This process achieves efficient collection of good and defective screws, reduces the need for manual intervention, and lowers production costs.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By using a single drive component to drive the screw conveyor and screw guide to form a screw screening gap, the screws are screened, reducing energy consumption and production costs;

[0029] 2. An adjustment component is added to adjust the gap between the screw guide and the screw conveyor, enabling the screening of screws of different specifications, thereby further improving production efficiency and reducing production costs. Attached Figure Description

[0034] The following further elaborates on this application Figures 1-3 in conjunction with the attached drawings.

[0035] Embodiment 1

[0036] An embodiment of this application discloses a waste separation device for a screw threading machine. Referring to Figure 1 and Figure 2 , it includes a frame 1 and a screening mechanism arranged inside the frame 1. The screening mechanism includes a driving and conveying unit 2, a screw guide 3, a material guiding component, and a collection component. The driving and conveying unit 2, the screw guide 3, the material guiding component, and the collection component are all installed on the frame 1. The frame 1 serves as the support structure of the entire device, and the driving and conveying unit 2, which is the power source of the screening mechanism, is located between the two side walls of the frame 1.

[0037] Among them, the driving and conveying unit 2 includes: a screw conveying part 21 and a driving part 22 for driving the screw conveying part 21 to convey. The driving part 22 is installed on the frame 1. The screw guide 3 and the screw conveying part 21 are arranged side by side in the horizontal direction between the two side walls of the frame 1. The edge of the screw guide 3 and the edge of the screw conveying part 21 are spaced apart in the length direction and enclose to form a screw screening gap 4. Specifically, the spacing of the screw screening gap 4 is a, the shaft diameter of the screw rod is b, and the head diameter of the screw is c, and the condition b < a < c needs to be satisfied, which can ensure that the spacing of the screw screening gap 4 can screen out defective screws.

[0038] The material guiding component is responsible for smoothly guiding the screws from the discharge port of the previous process into the screw screening gap 4. The non-defective screws and defective screws after screening respectively enter the collection component for collection, and finally the screening of the screws is completed.

[0039] Specifically, the drive transmission unit 2 also includes a connecting seat 23 mounted on the frame 1. The connecting seat 23 is used to mount the drive component 22 and provides a certain degree of protection for the drive component 22. The power source for the drive component 22 is an electric motor, a cylinder, or a hydraulic motor; in this embodiment, an electric motor is preferred. The screw transmission component 21 can be a transmission screw or a steel wire rope. The transmission screw has threads on its surface, while the steel wire rope has a rough surface, providing friction with the screw and enabling efficient transmission. In this embodiment, a transmission screw is preferred, as its installation is more convenient. Both can be connected to the drive component via a coupling to ensure stable transmission.

[0040] The conveying direction of the screw conveyor 21 forms an angle of less than 90° with the horizontal plane of the frame 1. The angle can be 15°, 30°, 45°, 60°, or 75°. In this embodiment, 30° is preferred, which helps to improve the screw screening effect.

[0041] The material guiding assembly includes a second material guiding component 7 and two first material guiding components 6. The two first material guiding components 6 are respectively fixed to the inner walls of both sides of the frame 1. Each first material guiding component 6 forms an angle of less than 90° with the side wall of the frame 1 towards the screw guide component 3. The angle can be 15°, 30°, 45°, 60°, or 75°, and is preferably 30° in this embodiment. The second material guiding component 7 is installed on the frame 1 and is located between the two first material guiding components 6. The two first material guiding components 6 and the second material guiding component 7 form a funnel-shaped discharge port. The screws fall from this discharge port into the screw screening gap 4. This structural design allows the screws to enter the screw screening gap 4 more smoothly, reducing the risk of blockage. Specifically, in this embodiment, both the first material guiding component 6 and the second material guiding component 7 are guide plates, because guide plates are simple in structure and readily available, effectively reducing costs.

[0042] The collection components include: a defective product guide plate 8 for collecting defective screws and a defective product collection box 9 connected to the outlet of the defective product guide plate 8; a good product guide plate 10 for collecting good product screws and a good product collection box 11 connected to the outlet of the good product guide plate 10. Defective screws that can completely pass through the screw screening gap 4 enter the defective product guide plate 8 and flow to the defective product collection box 9 for defective product collection. Screws that cannot pass through the screw screening gap 4 are good product screws. The head of the good product screws is stuck by the screw screening gap 4. With the cooperation of the screw conveyor 21 and the screw guide 3, the good product screws are conveyed to the good product guide plate 10 and then flow to the good product collection box 11 for good product collection.

[0043] The implementation principle of this embodiment is as follows: Compared to existing dual-drive schemes, such as those using dual drive components to drive screw conveyors, where defective screws fall through the screw screening gap between the two screw conveyors to separate defective and good screws, this embodiment uses only a single drive component 22 to drive the screw conveyor 21. A screw guide component 3 is added to guide the screw conveyor, forming a screw screening gap 4 in conjunction with the screw conveyor 21. Screws smoothly fall into the screw screening gap 4 through a funnel-shaped discharge port formed by the first guide component 6 and the second guide component 7. Guided by the screw guide component 3 and conveyed by the screw conveyor 21, good screws are conveyed to the good product guide plate 10 and flow to the good product collection box 11 for collection, while defective screws fall from the screw screening gap 4 to the defective product guide plate 8 and then flow to the defective product collection box 9 for collection, ultimately completing the screw screening. This reduces energy consumption and production costs.

[0044] Example 2

[0045] The difference between this embodiment 2 and the above embodiment 1 is that: (Refer to...) Figure 3 The connecting seat 23 is provided with an adjusting component 5, which includes a sliding block 51 and a bolt 52. The connecting seat 23 has a sliding groove on the side near the screw guide 3 and a through hole on the side away from the screw guide 3, and the through hole communicates with the sliding groove. The sliding block 51 is slidably disposed in the sliding groove, and the bolt 52 passes through the through hole and is screwed to the sliding block 51. The sliding direction of the sliding block 51 is perpendicular to the conveying direction of the screw conveyor 21. The sliding block 51 is connected to the screw guide 3 so that the screw guide 3 can slide along with the sliding block 51, thereby allowing the screw guide 3 to selectively move closer to or further away from the screw conveyor 21, thus making the spacing of the screw screening gap 4 adjustable (the rest is the same as in Embodiment 1).

[0046] The implementation principle of this embodiment is as follows: by rotating the bolt 52, the position of the sliding block 51 can be moved, thereby adjusting the position of the screw guide 3 to adjust the spacing of the screw screening gap 4, so as to meet the screening requirements of different types of screws, effectively reducing the debugging time caused by changes in screw specifications, improving production efficiency, and reducing production costs (the rest is the same as in Embodiment 1).

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
