Description

Technical Field

[0001] The present application relates to the technical field of anchor bolt production equipment, and in particular to an automatic screening and conveying equipment for square-bottom anchor rods. Background Art

[0002] There are different types of anchor bolts depending on their application. Some anchor bolts have a rectangular cross-section at the bottom end, which is used for special purposes. The expanded head of this type of anchor bolt is used for threaded connection with the anchor rod.

[0003] During the assembly process of this type of anchor rod after heat treatment, not only does it need to distinguish the bottom end's direction, but it also needs to be inserted into the corresponding barrel before the next assembly process of the end head and anchor rod. This barrel structure has a non-rotatable bottom plate that is slidably connected inside. A spring is installed under the bottom plate, and a square groove is opened on the upper surface of the bottom plate for the bottom end of the anchor rod to be inserted, thereby facilitating the threaded connection of the end head to the anchor rod.

[0004] In automated production, how to distinguish and regulate the orientation of the bottom end of the anchor rod and effectively insert the bottom end of the anchor rod into the square groove of the base plate is a design problem. Summary of the Invention

[0005] In order to realize the automatic screening and regularization of square bottom anchor rods and the insertion of the square bottom anchor rods into the square grooves of the bottom plate to improve the assembly efficiency of the square bottom anchor bolts, the present application provides an automatic screening and conveying device for square bottom anchor rods.

[0006] The present application provides an automatic screening and conveying device for square bottom anchor rods, which adopts the following technical solutions:

[0007] An automatic screening and conveying device for square bottom anchor rods, comprising

[0008] Push plate loader;

[0009] The screening plate is mounted at the end of the transmission belt of the push-plate loader, with a screening groove on the upper surface. The bottom wall of the screening groove is rotatably connected to a receiving plate. Sponge blocks are arranged on both sides of the receiving plate on the bottom wall of the screening groove. The sponge blocks are fixedly connected to the bottom of the receiving plate. Two extension plates are arranged diagonally on the upper surface of the receiving plate. Magnetic blocks are installed on the upper surface of the extension plates. A baffle is provided on the part of the screening plate away from the conveyor belt of the push-plate loader;

[0010] There are two feeding conveyor belts, which are set on both sides of the screening plate. They move in opposite directions and both move towards the bottom of the square bottom of the upper anchor rod. Both sides of the upper surface of the screening plate are inclined toward the feeding conveyor belts.

[0011] The screening cylinder is mounted above the screening plate, the piston rod is set downward and is installed with a lower pressure plate, the lower surface of the lower pressure plate is provided with lower pressure grooves at both ends, the lower pressure grooves are slidably connected with lower pressure blocks, and the upper surface of the lower pressure blocks is fixed with a lower pressure spring. When the anchor rod abuts against the baffle, one of the lower pressure blocks is located just above the square bottom of the lower end of the anchor rod, and the lower pressure block is in a natural state and extends out of the lower pressure groove;

[0012] The extension rod is arranged on the side wall of the lower pressure plate and is located just above the extension plate. A magnetic cylinder is fixedly provided at the end of the extension rod. The bottom of the magnetic cylinder is open and is slidably connected to a magnetic rod inside. The magnetic block is also fixed to the bottom end of the magnetic rod. A reset spring is fixedly provided at the top end of the magnetic rod. The top end of the reset spring is fixedly connected to the top end of the magnetic cylinder. A locking hole is provided inside the extension rod, and a locking rod is slidably connected to the locking hole. A locking spring is installed in the internal space of the extension rod. The locking spring can press the locking rod against the magnetic rod. A locking groove is provided on the side wall of the magnetic rod for the locking rod to be located therein. At this time, the reset spring is in a compressed state.

[0013] The locking rod is partially located in the lower pressing groove and abuts against the top wall of the lower pressing groove. The lower surface of the locking rod located in the lower pressing groove is inclined, and the upper surface of the lower pressing block corresponding to the locking rod is also inclined. When the lower pressing block abuts against the threaded portion of the anchor rod, the lower pressing block is completely located in the lower pressing groove. At this time, the inclined surface of the lower pressing block abuts against the inclined surface of the locking rod and drives the locking rod to disengage from the locking groove.

[0014] The magnetic rod can only make the corresponding two magnetic blocks attract each other after it pops out;

[0015] The end of the feeding conveyor belt is tilted downward and is provided with an anchor barrel. The top of the anchor barrel is trumpet-shaped, and the bottom ends of the anchor rods are stacked downward in the anchor barrel.

[0016] The initial conveyor belt is a chain conveyor belt equipped with a fixed cylinder. A bottom plate is slidably connected inside the fixed cylinder. The bottom plate is restricted from rotating by a sliding groove. A square groove is provided on the upper surface of the bottom plate. A spring is provided at the bottom of the bottom plate. An elastic film is provided on the top of the fixed cylinder to press against the anchor rod thread.

[0017] The bottom end of the anchor rod barrel is provided with a transfer assembly for inserting the anchor rod into the fixed barrel, and the initial conveyor belt is provided with an insertion assembly for inserting the bottom end of the anchor rod into the square groove.

[0018] Through the above technical solution, the anchor rod is pushed onto the conveyor belt on the push-plate loader and moves to the baffle, and abuts against the baffle after falling on the screening plate. Then the screening cylinder drives the lower pressure plate to move downward, and the lower pressure plate abuts against the anchor rod. The lower pressure block also abuts against the anchor rod. The lower pressure block abuts against the square bottom of the bottom end of the anchor rod is not completely located in the lower pressure groove, and the lower pressure block abuts against the threaded part of the anchor rod is completely located in the lower pressure groove. Then the lower pressure block abuts against the inclined surface of the locking rod through the inclined surface, driving the locking rod to disengage from the locking groove, so that the magnetic rod passes The two magnetic blocks are extended by their own gravity and elastic force, and attract each other. In the process of the screening cylinder driving the lower pressure plate to reset, the magnetic rod drives the receiving plate to rotate to one side through the attraction relationship, so that the anchor rod rolls on the feeding conveyor belt on one side. Then the two magnetic blocks separate from each other. The magnetic rod is pulled up by the reset spring and the locking rod is stuck in the locking groove during the upward movement, so that the magnetic rod is reset, and then the screening of the anchor rod is realized, so that the bottom ends of the anchor rods falling on the same feeding conveyor belt face the same direction. During the transportation of the anchor rod, it is sent to the anchor rod barrel through the tilt setting of the feeding conveyor belt and falls into the anchor rod barrel in a vertical state. It is then sent to the fixed barrel through the transfer component and inserted into the square groove of the bottom plate through the insertion component, so that the anchor rod is automatically screened and fixed in the fixed barrel.

[0019] Optionally, the transfer assembly includes side plates, a support plate, a transfer conveyor belt, and an insert plate;

[0020] The side plates are mounted on the bottom of the anchor barrel and extend toward the initial drive belt;

[0021] The support plate is fixed at the bottom of the side plate to support the anchor rod. The distance between the support plate and the anchor rod barrel is sufficient for one anchor rod to pass through in a vertical state.

[0022] The transfer conveyor belt is set on one side of the side plate, moves intermittently, and is a chain plate conveyor belt. Two plug plates are set in a group and are set on the chain plate. The interval is greater than the diameter of the anchor rod. When paused, there will be a group of plug plates located below the anchor rod tube and above the fixed tube. The support plate is provided with a drop hole above the fixed tube for the anchor rod to pass through.

[0023] Optionally, the transfer assembly further comprises a clamping cylinder which is mounted above the drop hole and which can move the top end of the anchor rod to below the insert plate after the piston rod is extended.

[0024] Optionally, the insertion assembly includes an insertion cylinder, a base frame, and an insertion frame;

[0025] The insertion cylinder is mounted above the initial conveyor belt, and the fixed cylinder for inserting the anchor rod will then come to rest below the insertion cylinder;

[0026] The insertion frame is fixedly connected to the bottom end of the piston rod of the insertion cylinder, and the top of the base frame is slidably connected to the insertion frame;

[0027] The bottom of the chassis is a supporting ring plate, which is used to abut against the surface of the initial transmission belt. The middle part of the chassis is a connecting rod, and the bottom end of the connecting rod abuts against the supporting ring plate. The top of the chassis is an outer ring plate and an inner ring shell. The bottoms of the outer ring plate and the inner ring shell are fixedly connected to the top of the connecting rod. The outer ring plate sleeves the inner ring shell therein, and a rotating ring is rotatably connected inside the inner ring shell. The inner and outer side walls of the inner ring shell are provided with ejection holes that are interconnected. The inner ring shell is provided with a plurality of clamping holes that are connected to the ejection holes. An ejection plate is slidably connected in the clamping hole, and an ejection spring is provided in the clamping hole so that the ejection plate only extends from the outside of the inner ring shell.

[0028] The bottom of the insertion frame is composed of multiple insertion plates, which are inserted between the outer ring plate and the inner ring shell. The insertion plates are provided with hook plates for lifting the bottom frame. The side wall and the lower surface of the insertion plates facing the inner ring shell are set in an arc transition and can abut against the ejection plate to press the ejection plate against the side wall of the anchor rod.

[0029] A guide block is fixed on the side wall of the ejector plate facing the hook plate, and a guide groove is opened on the side wall of the insert plate facing the inner ring shell. The bottom of the guide groove is vertically arranged and directly faces the guide block, and the top is inclined outward.

[0030] A top plate is fixed on the upper surface of the inner ring shell, and the bottom frame can use its own gravity to make the top plate push the anchor rod into the bottom plate to compress the spring.

[0031] Optionally, the inner ring shell is provided with a rotation torsion spring to enable the rotating ring to reset.

[0032] Optionally, a cross bar is provided between the connecting rods so that the insert plate can only slide vertically relative to the connecting rods.

[0033] Optionally, the extension plate is provided with a partially rotating connection arrangement for mounting the magnetic block.

[0034] Optionally, an anti-slip plate is provided at the bottom of the circumferential outer wall of the magnetic rod, and the anti-slip plate abuts against the inner bottom wall of the magnetic cylinder to separate the two magnetic blocks.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] The arrangement of the lower pressing plate, the lower pressing block and the magnetic rod can realize the flipping of the receiving plate by the popping out of different magnetic rods during the pressing and resetting process, thereby realizing the automatic screening of the orientation of the anchor rods, so that the bottom ends of the anchor rods falling on the same feeding conveyor belt are oriented in the same direction;

[0037] After the anchor rod falls from the anchor rod barrel to the support plate, it is located between a set of plug plates. Then, it moves to the top of the fixed barrel through the movement of the transfer belt and falls into the fixed barrel through the drop hole. Then, it is pushed downward by the piston rod of the compression cylinder, so that the anchor rod is more stably inserted into the fixed barrel and located under the plug plates.

[0038] The insertion cylinder drives the insertion frame and the base frame to move downward. During the process of the base frame and the initial transmission belt surface, the anchor rod is pressed down to the position where the spring under the base plate is compressed. Then the insertion plate moves down to abut against the ejection plate and drives the ejection plate to extend to clamp the anchor rod, and drives the rotating ring to rotate through the abutment relationship between the guide block and the guide groove, thereby driving the anchor rod to rotate. In this process, if the square groove of the anchor rod matches the square bottom of the bottom end of the anchor rod, the base plate moves up so that the bottom end of the anchor rod is located in the square groove of the base plate, realizing the automatic placement of the anchor rod in the fixed cylinder.

[0048] The following is combined with Figure 1-8 This application is described in further detail.

[0049] The embodiment of the present application discloses an automatic screening and conveying device for square-bottom anchor rods.

[0050] refer to Figure 1 and Figure 2The automatic screening and conveying equipment for square-bottom anchor rods includes a push-plate loader 1, a screening plate 2, a screening assembly 3, a feeding conveyor belt 4, an anchor rod barrel 5, a transfer assembly 6, an insertion assembly 7, an initial conveyor belt and a fixed barrel 91. The top of the push-plate loader 1 is a conveyor belt, and the screening plate 2 is mounted at the end position of the transmission belt of the push-plate loader 1. A screening groove 21 is provided on the upper surface, and a receiving plate 22 is rotatably connected to the inner bottom wall of the screening groove 21. Sponge blocks 223 are provided on both sides of the receiving plate 22 on the inner bottom wall of the screening groove 21, and the sponge blocks 223 are fixedly connected to the bottom of the receiving plate 22. The upper surface of the receiving plate 22 is an arc-shaped concave setting and is used to place an anchor rod. A baffle is provided on the part of the screening plate 2 away from the conveyor belt of the push-plate loader 1. There are two feeding conveyor belts, which are arranged on both sides of the screening plate 2. The moving directions are opposite and both are toward the direction of the square bottom of the upper anchor rod. The two sides of the upper surface of the screening plate 2 are inclined toward the feeding conveyor belt. The screening assembly 3 is set above the receiving plate 22 and is used to drive the receiving plate 22 to flip in different directions so that the anchor rods facing the same direction fall on the same feeding conveyor. The end of the feeding conveyor is tilted downward, and the anchor rod barrel 5 is mounted on the end of the feeding conveyor. The anchor rod barrel 5 is set vertically and has a trumpet-shaped top. The initial conveyor is a chain plate conveyor, equipped with a fixed barrel 91, and the fixed barrel 91 is connected to the bottom plate 92 (refer to Figure 7 The bottom plate 92 is restrained from rotating by a sliding groove. A square groove 921 is defined on its upper surface. A spring is installed at the bottom of the bottom plate 92, and an elastic film 93 is installed at the top of the fixing barrel 91 to tighten against the anchor rod threads. The transfer assembly 6 is positioned below the anchor rod barrel 5 and is used to move the anchor rod into the fixing barrel 91. The insertion assembly 7 is positioned above the initial transmission belt 9 and is used to insert the bottom end of the anchor rod into the square groove 921 of the bottom plate 92.

[0051] The anchor rods are loaded onto the push-plate loader 1 and moved onto the transmission belt, where they fall onto the receiving plate 22. The screening assembly 3 then screens the anchor rods, causing the receiving plate 22 to reverse in the corresponding direction and roll the anchor rods onto the corresponding feed conveyor belt 4, thereby ensuring that the anchor rods on the feed conveyor belt 4 face the same direction. The rods are then moved to the end of the feed conveyor belt 4, tilted downward, and sent to the anchor rod barrel 5. Through the trumpet-shaped guide, they are vertically inserted into the anchor rod barrel 5 and stacked. The lowest anchor rod is moved into the fixed barrel 91 via the transfer assembly 6, and the square bottom of the anchor rod is inserted into the square groove 921 via the insertion assembly 7, enabling automatic sorting of the anchor rods and insertion into the fixed barrel 91. This facilitates subsequent threaded connection of the anchor rods with the end caps, improving the efficiency of automated assembly of square-bottom anchor rods.

[0052] refer to Figure 2 and Figure 3The screening assembly 3 includes a screening cylinder 31, a lower pressure plate 32 and a magnetic rod 33. Two extension plates 221 are diagonally arranged on the upper surface of the receiving plate 22, and the extension plates 221 are tilted along the diagonal line. A magnetic block 222 is installed on the upper surface of the extension plate 221, and the part of the extension plate 221 on which the magnetic block 222 is installed is rotatably connected. The screening cylinder 31 is mounted above the screening plate 2, and the piston rod is downwardly arranged and fixedly connected to the lower pressure plate 32. A lower pressure groove 321 is provided at both ends of the lower surface of the lower pressure plate 32, and a lower pressure block 322 is slidably connected in the lower pressure groove 321. A lower pressure spring 3221 is fixedly provided on the upper surface of the lower pressure block 322, and the top end of the lower pressure spring 3221 is fixedly connected to the inner top wall of the lower pressure groove 321. When the anchor rod abuts against the baffle, one of the lower pressure blocks 322 is located directly above the square bottom of the lower end of the anchor rod, and the lower pressure block 322 extends out of the lower pressure groove 321 when it is in a natural state.

[0053] refer to Figure 3 and Figure 4 Two extension rods 323 are fixed at the corners of the side walls of the lower pressure plate 32, and the extension rods 323 are located directly above the extension plate 221. A magnetic cylinder 324 is fixed at the end of the extension rod 323, and the bottom of the magnetic cylinder 324 is opened. The magnetic rod 33 is vertically slidably connected in the magnetic cylinder 324 and extends from the bottom end. The magnetic block 222 is also provided at the bottom end of the magnetic rod 33 and can be attracted to the magnetic block 222 on the extension plate 221. A reset spring 333 is fixed at the top of the magnetic rod 33, and the top of the reset spring 333 is fixedly connected to the top of the magnetic cylinder 324. The extension rod 323 has a locking hole 3231 formed within it, to which a locking rod 3232 is slidably connected. A locking spring 3233 is mounted within the interior of the extension rod 323, securing the locking rod 3232 against the magnetic rod 33. A locking groove 332 is formed on the sidewall of the magnetic rod 33, allowing the locking rod 3232 to rest within it. In this state, the return spring 333 is compressed. The locking rod 3232 is partially positioned within the lower pressure groove 321 and abuts against the inner top wall of the lower pressure groove 321. The lower surface of the locking rod 3232 located within the lower pressure groove 321 is tilted, as is the upper surface of the lower pressure block 322 corresponding to the locking rod 3232. When the lower pressure block 322 abuts the threaded portion of the anchor rod, the lower pressure block 322 is completely located in the lower pressure groove 321. At this time, the inclined surface of the lower pressure block 322 abuts the inclined surface of the locking rod 3232, driving the locking rod 3232 to disengage from the locking groove 332. The magnetic rod 33 can only attract the corresponding two magnetic blocks 222 after it is ejected. An anti-slip plate 331 is provided at the bottom of the circumferential outer wall of the magnetic rod 33. When the anti-slip plate 331 abuts the inner bottom wall of the magnetic tube 324, the two magnetic blocks 222 are separated, and the return spring 333 is stretched to near its limit length.

[0054] After the anchor rod moves onto the receiving plate 22, it abuts against the baffle and stops moving. Then, the screening cylinder 31 drives the lower pressure plate 32 downward, and the lower pressure plate 32 is pressed tightly against the anchor rod. At this time, the lower pressure block 322 facing the square bottom of the anchor rod is not completely located in the lower pressure groove 321, and the lower pressure block 322 facing the threaded portion of the anchor rod is completely located in the lower pressure groove 321. Then, the inclined surface of the lower pressure block 322 abuts against the inclined surface of the locking rod 3232, driving the locking rod 3232 out of the locking groove 332. The magnetic rod 33 pops out under the action of its own weight and the elastic force of the reset spring 333, causing the two magnetic blocks 222 to attract each other. The lower pressure plate 32 then moves upward and resets. During this process, the magnetic rod 33 pulls on the extension plate 221, driving the receiving plate 22 to rotate to one side, causing the anchor rod to fall onto the feed conveyor belt on one side. When the magnetic rod 33 is pulled until the anti-slip plate 331 contacts the inner bottom wall of the magnetic cylinder 324, the two magnetic blocks 222 are pulled apart, and the magnetic rod 33 is reset under the tension of the reset spring 333. During the reset process, the locking rod 3232 is inserted into the locking groove 332 to fix the position of the magnetic rod 33. In this way, the different positions of the anchor rod bottom can effectively drive the receiving plate 22 to tilt in different directions, thereby realizing automatic screening of the anchor rod orientation.

[0055] refer to Figure 5 The transfer assembly 6 includes a side plate 61, a support plate 62, a transfer conveyor belt 63, an insert plate 64, and a clamping cylinder 65. The side plate 61 is mounted on the bottom of the anchor barrel 5 and extends above the initial transmission belt 9. The support plate 62 is fixed to the bottom of the side plate 61 to support the anchor rod. The distance between the support plate 62 and the anchor barrel 5 is sufficient for one anchor rod to pass through in an upright position. The transfer conveyor belt 63 is mounted on one side of the side plate 61 and moves intermittently. It is a chain plate conveyor belt. The chain plates of the transfer conveyor belt 63 are arranged vertically. The insert plates 64 are arranged in groups of two on the chain plates, with a spacing greater than the diameter of the anchor rod. When the transfer conveyor belt 63 stops, a group of insert plates 64 will be located below the anchor barrel 5 and above the fixed barrel 91. The support plate 62 is provided with a drop hole 621 above the fixed barrel 91 for the anchor rod to pass through. The clamping cylinder 65 is mounted above the drop hole 621. After the piston rod is extended, it can move the top of the anchor rod to the bottom of the insert plate 64.

[0056] The anchor rod falls onto the support plate 62 in the anchor rod barrel 5 and is located between a set of insert plates 64. The transfer belt then rotates, driving the anchor rod to move above the fixed barrel 91 through the insert plates 64, and stops above the fixed barrel 91. The anchor rod falls into the fixed barrel 91 through the drop hole 621. Finally, the piston rod of the clamping cylinder 65 is extended to press the anchor rod down into the fixed barrel 91, so that the anchor rod is located below the insert plates 64, thereby facilitating the movement of the insert plates 64 and improving the stability of the anchor rod inserted into the fixed barrel 91.

[0057] refer to Figure 6The insertion assembly 7 includes an insertion cylinder 71, an insertion frame 72, and a base frame 73. The insertion cylinder 71 is mounted above the initial transmission belt 9. The fixed cylinder 91 first passes under the drop hole 621 and then under the insertion cylinder 71. The insertion frame 72 is fixedly connected to the bottom end of the piston rod of the insertion cylinder 71, and the top of the base frame 73 is slidably connected to the insertion frame 72.

[0058] refer to Figure 7 and Figure 8 The base frame 73 includes a support ring plate 731, a connecting rod 732, an outer ring plate 733 and an inner ring shell 734. The support ring plate 731 is located at the bottom and is used to abut against the surface of the initial transmission belt 9. The outer ring plate 733 and the inner ring shell 734 are both located at the top, with the outer ring plate 733 located on the outside. A plurality of connecting rods 732 are vertically arranged to connect the outer ring plate 733, the inner ring shell 734 and the support ring plate 731. A rotating ring 8 is rotatably connected to the inner ring shell 734. The inner and outer side walls of the inner ring shell 734 are provided with ejection holes 7341 that are connected to each other, and the side wall of the rotating ring 8 is provided with a clamping hole 81 that is connected to the ejection hole 7341. An ejection plate 82 is slidably connected to the clamping hole 81, and an ejection spring 83 is provided in the clamping hole 81 so that the ejection plate 82 only extends from the outside of the inner ring shell 734. There are three ejector blocks, equidistantly spaced about the central axis of the rotating ring 8. A top plate 7342 is fixed to the upper surface of the inner ring shell 734, located at the center of the inner ring shell 734. The bottom frame 73, through its own weight, enables the top plate 7342 to push the anchor rod into the bottom plate 92, compressing the spring.

[0059] The bottom of the insertion frame 72 is composed of multiple insertion plates 721. In this embodiment, there are three insertion plates 721, which are equidistantly distributed around the central axis of the rotating ring 8. The insertion plates 721 can be inserted between the outer ring plate 733 and the inner ring shell 734, and abut against the circumferential inner wall of the outer ring plate 733. A hook plate 7211 is fixed to the bottom of the side wall of the insertion plate 721 away from the inner ring shell 734. The hook plate 7211 can abut against the lower surface of the outer ring plate 733 to lift the base frame 73. The position of the insertion plate 721 is opposite to that of the ejector plate 82. The side wall and lower surface of the insertion plate 721 facing the inner ring shell 734 are set in an arc transition. When the insertion plate 721 abuts against the ejector plate 82 toward the side wall of the inner ring shell 734, the ejector plate 82 extends to press the side wall of the anchor rod tightly. A guide block 821 is fixed to the side of the ejector plate 82 facing the hook plate 7211. A guide groove 7212 is defined on the side of the insert plate 721 facing the inner ring housing 734. The bottom of the guide groove 7212 is vertically aligned and faces the guide block 821, while the top is tilted outward. A torsion spring is installed in the inner ring housing 734 to reset the rotating ring 8. A crossbar is interposed between the connecting rods 732, ensuring that the insert plate 721 can only slide vertically relative to the connecting rods 732.

[0060] The insertion cylinder 71 moves downward, causing the insertion frame 72 and the base frame 73 to move downward together. During the downward movement of the base frame 73, the top plate 7342 contacts the top of the anchor rod, driving the anchor rod to continue to move downward. When the support bottom ring contacts the initial conveyor belt, the top plate 7342 presses the anchor rod downward until the spring below the base plate 92 is compressed. The insertion plate 721 then moves downward relative to the base frame 73, contacting the ejector plate 82 and driving the ejector plate 82 to extend toward the inner ring shell 734, causing the ejector plate 82 to clamp the anchor rod. Subsequently, as the guide block 821 contacts the inclined portion of the guide groove 7212, the rotating ring 8 rotates, causing the anchor rod to rotate. During this process, if the square bottom of the anchor rod aligns with the square groove 921, the base plate 92 pops out, positioning the square bottom within the square groove 921. After the guide block 821 separates from the guide groove 7212, the ejector plate 82 pops out and returns to its original position, releasing the anchor rod. Then, during the upward movement of the insert plate 721, the insert plate 721 separates from the side wall of the ejection plate 82 and the rotating ring 8 rotates to reset. Then, the insert plate 721 lifts the bottom plate 92 upward and resets it through the hook plate 7211. This effectively realizes the automated process of inserting the square bottom of the anchor rod into the square groove 921 of the bottom plate 92.

[0061] The implementation principle of the automatic screening and conveying equipment for square-bottom anchor rods in the embodiment of the present application is as follows: the anchor rods are loaded on the push-plate loader 1 and are intercepted by the baffle when they move to the receiving plate 22 along with the transmission belt. Subsequently, the lower pressure plate 32 moves downward to abut against the anchor rod. The lower pressure plate 32 opposite to the threaded portion of the anchor rod is completely located in the lower pressure groove 321 and abuts against the inclined surface of the locking rod 3232 through the inclined surface, driving the locking rod 3232 to separate from the locking groove 332. The magnetic rod 33 pops out to cause the two magnetic blocks 222 to engage. During the resetting process of the upper pressure plate, the receiving plate 22 is pulled by the magnetic rod 33 to flip over and move the anchor rod to the corresponding feeding conveyor, thereby realizing automatic screening of the square bottom orientation of the anchor rod. The anchor rod moves into the anchor rod barrel 5 on the feeding conveyor, is moved to the blanking hole by the insert plate 64, and is inserted into the fixed barrel 91, and is pressed into the fixed barrel 91 by the clamping cylinder 65. It then moves to the bottom of the insertion cylinder 71, and the insertion frame 72 drives the base frame 73 downward. The spring under the bottom plate 92 is compressed, and the insertion plate 721 then moves downward, driving the ejector plate 82 to extend and clamp the anchor rod. The guide block 821 then abuts against the guide groove 7212, driving the rotating ring 8 to rotate, thereby achieving rotation of the anchor rod. During this process, when the square groove 921 of the bottom plate 92 is aligned with the square bottom of the anchor rod, the bottom plate 92 pops out, positioning the square bottom within the square groove 921. The ejector plate 82 then resets, and as the insertion plate 721 moves upward, the rotating ring 8 resets, driving the bottom plate 92 upward and reset. This achieves automatic screening of square-bottom anchor rods and their insertion into the square groove 921 in the fixed cylinder 91, thereby improving the efficiency of square-bottom anchor rod assembly.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
