[0001] The invention relates to the technical field of anchor bolt production equipment, and more particularly to an automatic feeding device for producing sleeve type expansion anchor bolts. Background Art

[0002] Anchor bolts refer to the general term for all post-anchoring components. According to different anchoring mechanisms, they can be divided into expansion anchor bolts, expansion hole anchor bolts and other types. The main material of the anchor bolt is the anchor bolt. In addition to the expansion structure, the anchor bolt is also equipped with at least a gasket and a nut. Some anchor bolts are also equipped with spring washers. Therefore, the production and processing of anchor bolts requires multiple links.

[0003] In the prior art, in the production of sleeve expansion anchors, a push plate loader is needed to load the anchors, transport the anchors to the feeding conveyor belt, and then transport the anchors through the feeding conveyor belt. When the push plate loader loads the anchors, the orientations of the anchors are inconsistent. During the transportation of the feeding conveyor belt, the orientations of the anchors need to be changed to make all the anchors in the same orientation, and then a line drawing mechanism is used to draw lines on the anchors. When changing the orientation and drawing lines, the anchors can only be operated one by one, and the feeding conveyor belt needs to stop working, resulting in low work efficiency and reduced production efficiency. In addition, when the push plate loader loads the anchors, the anchors are easily stacked together and the anchors are easily dropped from the push plate.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

Detailed implementation mode

[0016] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation mode of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0017] The embodiment of the present application provides an automatic feeding device for the production of sleeve expansion anchor bolts. Please refer to Figure 1-Figure 7 : It includes a push plate type loading machine 1 and a feeding conveyor belt 2. The push plate type loading machine 1 includes two movable push plates 3 and a fixed push plate 4. The movable push plates 3 and the fixed push plate 4 are assembled in a staggered stepped manner. An anchor bolt line drawing mechanism is provided on the push plate type loading machine 1, and an anchor bolt arranging and conveying mechanism is provided on the push plate type loading machine 1; The anchor bolt line drawing mechanism includes a fixed cavity 5, an inner groove 6, a drooping opening 7, a side opening 8, a line drawing part 9 and an extrusion ink application part 10. The fixed cavity 5 is arranged inside the fixed push plate 4. The inner groove 6 is opened on the surface of the fixed push plate 4. The drooping opening 7 communicates between the fixed cavity 5 and the inner groove 6. The side opening 8 is opened on both sides of the fixed push plate 4 and the push plate type loading machine 1. The line drawing part 9 positions and draws lines on the anchor bolts, and the extrusion ink application part 10 extrudes the line drawing part 9 and applies ink.

[0018] Specifically, in actual application, the top ends of the movable push plate 3 and the fixed push plate 4 are inclined backward. The anchor bolts are stored in the push plate type loading machine 1. The two movable push plates 3 lift. The front movable push plate 3 pushes the anchor bolts onto the fixed push plate 4. The anchor bolts on the fixed push plate 4 are then pushed onto the rear movable push plate 3. The rear movable push plate 3 pushes the anchor bolts onto the feeding conveyor belt 2 to convey the anchor bolts. The push plate type loading machine 1 is a prior art, so no detailed description will be given; After the front movable push plate 3 pushes the anchor bolt to the fixed push plate 4, the anchor bolt falls into the inner groove 6 at the top of the fixed push plate 4. The inner groove 6 prevents the anchor bolt from rolling backward. After the anchor bolt enters the inner groove 6, the screw part of the anchor bolt droops through the drooping opening 7, and the screw part of the anchor bolt passes through the drooping opening 7 and enters the fixed cavity 5. The head of the anchor bolt is located above the drooping opening 7, and the anchor bolt is in a vertically downward state. The extrusion ink application part 10 is squeezed against the line drawing part 9 for ink application, and the line drawing part 9 positions and draws a line on the anchor bolt.

[0019] Refer to the attached drawings of the specification Figure 1 , the attached drawings of the specification Figure 2 and the attached drawings of the specification Figure 4 , the line drawing part 9 includes fixed support plates 11 installed on both sides of the push plate type loader 1. The fixed support plates 11 are located below the side opening 8. A rotating shaft 12 is rotatably connected to the fixed support plates 11. An axial slot 13 is formed on the rotating shaft 12. A line drawing cotton strip 14 is arranged between the two rotating shafts 12. Both ends of the line drawing cotton strip 14 are located in the axial slot 13. The line drawing cotton strip 14 passes through the fixed cavity 5 through the side opening 8. A driving motor 15 is installed on one side of the fixed support plate 11, and the output end of the driving motor 15 is fixedly connected to the rotating shaft 12.

[0020] Specifically, in actual application, when the anchor bolt is in a vertically downward state, the screw part of the anchor bolt is located between the line drawing cotton strips 14. The driving motor 15 starts to work. The output end of the driving motor 15 drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 conveys the line drawing cotton strip 14. The line drawing cotton strip 14 is conveyed along the axial slot 13 on the rotating shaft 12 to prevent the line drawing cotton strip 14 from falling off the rotating shaft 12. The line drawing cotton strip 14 contacts the screw part of the anchor bolt. When the line drawing cotton strip 14 is conveyed, the line drawing cotton strip 14 can drive the anchor bolt to rotate. The line drawing cotton strip 14 applies ink to the screw part of the anchor bolt, which is convenient for drawing a line on the anchor bolt. Multiple anchor bolts can be drawn at the same time, the drawing position is accurate, the work efficiency is improved, and the production efficiency is improved.

[0021] Refer to the attached drawings of the specification Figure 4 , the attached drawings of the specification Figure 5 , the attached drawings of the specification Figure 6 and the attached drawings of the specification Figure 7 , the extrusion ink application part 10 includes fixed side plates 16 installed on both sides of the fixed support plate 11. A power push rod 17 is installed on the fixed side plates 16. Two U-shaped push plates 18 are arranged in the fixed cavity 5. The open ends of the two U-shaped push plates 18 face the line drawing cotton strip 14. The telescopic end of the power push rod 17 is fixedly connected to the U-shaped push plate 18. An ink absorbing sponge 19 is installed at the open end of the U-shaped push plate 18. The line drawing cotton strip 14 contacts the ink absorbing sponge 19. A storage ink cavity 20 is arranged in the U-shaped push plate 18. An ink absorbing cotton strip 21 is arranged in the storage ink cavity 20. One end of the ink absorbing cotton strip 21 is fixedly connected to the ink absorbing sponge 19.

[0022] Specifically, in actual applications, when the anchor bolt is in a vertically downward state, the power push rod 17 starts to work. The telescopic end of the power push rod 17 extends in to drive the C-shaped push plate 18 to move. The two C-shaped push plates 18 approach the drawing cotton strip 14. The C-shaped push plate 18 pushes the drawing cotton strip 14 close to the anchor bolt through the ink-absorbing sponge 19, so that the drawing cotton strip 14 contacts the anchor bolt, avoiding the generation of breakpoints during drawing, improving the drawing effect. The ink-absorbing cotton strip 21 absorbs the ink in the storage ink cavity 20. The ink-absorbing cotton strip 21 conveys the ink to the ink-absorbing sponge 19. The ink-absorbing sponge 19 is filled with ink. The drawing cotton strip 14 is stained with ink when contacting the ink-absorbing sponge 19, facilitating drawing. After drawing is completed, the power push rod 17 drives the C-shaped push plate 18 to reset.

[0023] Refer to the attached instructions Figure 2 and the attached instructions Figure 7 As shown in the attached drawings, the anchor bolt arrangement and conveying mechanism includes a multi-stage telescopic cylinder 22 installed in the fixed cavity 5. A lifting plate 23 is installed on the telescopic end of the multi-stage telescopic cylinder 22. Both ends of the lifting plate 23 penetrate through the side opening 8 and extend out of the push plate type feeder 1. A single-chain conveyor 24 is installed on the lifting plate 23. The chain of the single-chain conveyor 24 penetrates through the fixed cavity 5. L-shaped support plates 25 are installed on both sides of the push plate type feeder 1. The L-shaped support plates 25 are located above the side opening 8. A belt conveyor 26 is installed between the two L-shaped support plates 25. The belt of the belt conveyor 26 penetrates through the side opening 8. The belt of the belt conveyor 26 is located above the fixed push plate 4. A plurality of fixed拨动 plates 27 are installed on the surface of the belt of the belt conveyor 26. The plurality of fixed拨动 plates 27 are evenly distributed on the surface of the belt. The distance between the fixed拨动 plate 27 and the fixed push plate 4 is the same as the head diameter of the anchor bolt.

[0024] It should be noted that the term "拨动板" in Chinese is not very clear. I translated it as "拨动板" directly. If there is a more accurate English term for it, it can be adjusted accordingly.Specifically in practical applications, after the line is drawn, the multi-stage telescopic cylinder 22 starts to work. The telescopic extension of the multi-stage telescopic cylinder 22 drives the lifting plate 23 and the single-chain conveyor 24 to rise. At the same time, the single-chain conveyor 24 starts to work, and the chain on the single-chain conveyor 24 starts to convey. During the rising process, the chain of the single-chain conveyor 24 contacts the bottom end of the anchor bolt. During the conveying process of the chain of the single-chain conveyor 24, the bottom of the anchor bolt is tilted to the right side. Multiple anchor bolts can be tilted to the right simultaneously, enabling the heads of the anchor bolts to maintain the same orientation. There is no need to adjust the orientation of each anchor bolt one by one, and there is no need to stop the feeding conveyor belt 2 for feeding, which improves the production efficiency. After the anchor bolts have the same orientation, the lifting plate 23 and the single-chain conveyor 24 continue to rise, moving the entire anchor bolt out of the fixed cavity 5. The belt conveyor 26 starts to work, and the belt on the belt conveyor 26 drives the fixed shifting plate 27 to move. In the case of stacked anchor bolts, the upper anchor bolts are shifted to the right by the fixed shifting plate 27 to prevent the anchor bolts from stacking together and avoid the stacked anchor bolts from falling off the fixed push plate 4. After all the anchor bolts are laid flat, the lifting plate 23 and the single-chain conveyor 24 continue to rise, making the anchor bolts level with the top of the fixed push plate 4. After the movable push plate 3 at the rear end descends, the anchor bolts on the fixed push plate 4 roll onto the movable push plate 3 at the rear end, and the movable push plate 3 at the rear end pushes the anchor bolts onto the feeding conveyor belt 2 for conveying the anchor bolts.

[0025] Refer to the attached instruction manual Figure 3 On the surface of the inner groove 6, there are multiple anti-slip protrusions 28, and the multiple anti-slip protrusions 28 are evenly distributed on the surface of the inner groove 6.

[0026] Specifically in practical applications, when the anchor bolts are laid flat, the heads of the anchor bolts are located between adjacent anti-slip protrusions 28. When the fixed shifting plate 27 shifts the anchor bolts, it prevents the lower anchor bolts from shifting.

[0027] Refer to the attached instruction manual Figure 4 and the attached instruction manual Figure 5 On both sides of the U-shaped push plate 18, there are shaft brackets 29 installed. A guiding rotating shaft 30 is rotatably connected to the shaft brackets 29. The line-drawing cotton strip 14 contacts the guiding rotating shaft 30. On one side of the top of the U-shaped push plate 18, there is an ink filling port 31, and the ink filling port 31 is communicated with the storage ink cavity 20. The ink filling port 31 is located outside the push plate type loading machine 1.

[0028] Specifically in practical applications, when the line-drawing cotton strip 14 is conveyed, the line-drawing cotton strip 14 contacts the guiding rotating shaft 30, and the guiding rotating shaft 30 rotates to guide the line-drawing cotton strip 14, preventing the line-drawing cotton strip 14 from contacting the U-shaped push plate 18, reducing the wear of the line-drawing cotton strip 14, and improving the service life of the line-drawing cotton strip 14. The line-drawing cotton strip 14 is made of an elastic material, and the line-drawing cotton strip 14 can be stretched. It is convenient to add ink into the storage ink cavity 20 through the ink filling port 31.

[0029] Refer to the appended drawings of the specification Figure 4 、Refer to the appended drawings of the specification Figure 5 and the appended drawings of the specification Figure 6 The width of the lifting plate 23 is less than the width of the drooping opening 7, and the width of the lifting plate 23 is less than the distance between the two U-shaped push plates 18. The lifting plate 23 can pass through between the two U-shaped push plates 18, and the diameter of the rotating shaft 12 is larger than the width of the lifting plate 23.

[0030] Specifically, in actual application, the lifting plate 23 and the single-chain conveyor 24 can pass through between the drawn cotton strips 14 and rise, and the single-chain conveyor 24 can pass through the drooping opening 7.

[0031] Refer to the appended drawings of the specification Figure 2 The belt conveyor 26 uses an extremely narrow belt, and the width of the belt on the belt conveyor 26 is less than the width of the drooping opening 7.

[0032] Specifically, in actual application, the width of the belt on the belt conveyor 26 is less than the width of the drooping opening 7, and the belt conveyor 26 and the fixed拨动 plate 27 do not affect the movement of the anchor bolts towards the movable push plate 3.
