Description

Technical Field

[0001] This application relates to the technical field of bar stock inspection and processing, and in particular to an automated bar stock feeding device. Background Technology

[0002] Many industrial production processes require the use of short bars. These bars are generally formed by cutting equal-length segments from longer rods. After cutting, the bars need to undergo milling, electroplating, painting, and quality inspection. Because of their short length, the cut bars may be piled up haphazardly, affecting subsequent milling, electroplating, painting, and quality inspection processes. Therefore, to ensure the smooth operation of these processes, the bars need to be organized and transported one by one to the appropriate equipment.

[0003] Currently, the main method relies on manual labor to feed the bars into the equipment one by one. This method is too labor-intensive and the efficiency is difficult to guarantee. Furthermore, the placement accuracy of the bars cannot be guaranteed when they are placed manually. Therefore, this method needs to be improved. Summary of the Invention

[0004] The purpose of this application is to provide an automated bar stock feeding device, which can achieve precise automated bar stock feeding, effectively reduce labor costs, and ensure production efficiency.

[0005] The present application provides an automated bar stock feeding device, which adopts the following technical solution.

[0006] An automated bar stock feeding device includes:

[0007] The frame, which plays a major supporting and load-bearing role;

[0008] A material box is used to hold bar stock in batches. The lower end of the material box has a closable discharge port, through which the bar stock inside the material box can fall. The discharge port can only accommodate one bar stock at a time.

[0009] A material box positioning assembly is mounted on the frame and is used to drive the material box to perform horizontal positioning along the width direction.

[0010] A material box opening and closing assembly is disposed on one side of a material box positioning assembly, and the material box opening and closing assembly is used to control the opening and closing of the material discharge port at the lower end of the material box;

[0011] And a material distribution assembly, which is mounted on the frame, with the feeding end of the material distribution assembly close to the end of the material box positioning assembly, and the discharging end of the material distribution assembly connected to the equipment. The material distribution assembly is used to push the bar material falling from the material box into the equipment.

[0012] When the material box is installed on the material box positioning component, the material box's discharge port is located directly above the feeding end of the material distribution component. When the material distribution component (7) moves the bar material into the equipment, the material distribution component (7) blocks the material box's discharge port.

[0013] By adopting the above technical solution, during use, several bars are added to the material box, ensuring that the axes of each bar are parallel. The material box is then placed on the material box positioning component for horizontal positioning. The material box opening and closing component controls the opening of the dropping port at the bottom of the material box, allowing the bars inside the material box to fall one by one onto the feeding end of the material separating component under the action of gravity. Finally, the material separating component pushes the fallen bars one by one into the equipment, thereby achieving the requirement of automatic and equidistant feeding of the bars. Because the bars are fed at equidistant intervals, the feeding position of the bars is also precisely controlled.

[0014] Optionally, the material box includes:

[0015] The outer casing has an open upper end and a material discharge port at its lower end.

[0016] The inner box is detachably installed inside the outer shell. One long side of the inner box is open to facilitate the placement of bar stock. The lower end of the inner box has a discharge port that communicates with the material drop port.

[0017] And a material blocking mechanism, which is located inside the lower end of the inner box and is used to block the material outlet and the material drop outlet;

[0018] The inner box contains a guide plate, the upper end of which is connected to the inner wall of the inner box, and the lower end of which is located near the discharge port. The baffle mechanism is located between the guide plate and the bottom surface of the inner box.

[0019] By adopting the above technical solution, the inner box is placed horizontally with the open side facing upwards. At this time, the workers can place each bar vertically inside the inner box and then install the inner box into the outer shell, thus completing the material replenishment work of the material box. When the material box is upright, all the bars inside the inner box are in a horizontal state. At this time, the bar at the bottom of the inner box can slide down along the inclined direction of the guide plate, so that the bar at the bottom of the inner box can fall through the discharge port of the inner box. The material blocking mechanism can block the discharge port, thus preventing the bars inside the material box from falling directly through the discharge port when the material box is upright.

[0020] Optionally, the material stopping mechanism includes:

[0021] A fixing plate, the upper and lower ends of which are respectively connected to the bottom surface of the guide plate and the bottom of the inner box;

[0022] A baffle plate, which is L-shaped, has one end attached to the bottom surface of the inner box and can pass through the lower end of the guide plate to block the outlet. The other end of the baffle plate is close to the fixing plate.

[0023] A guide rod, one end of which is fixedly connected to a baffle plate, and the other end of which passes through a fixed plate;

[0024] And a reset spring, which is sleeved on the guide rod, with its two ends abutting against the fixed plate and the baffle plate respectively;

[0025] The outer casing has a waist-shaped groove on its side, and the material box opening and closing assembly can extend into the outer casing through the waist-shaped groove to move the baffle plate.

[0026] By adopting the above technical solution, when the material blocking mechanism is in use, by moving the material blocking plate away from the material discharge port, the material discharge port and the material discharge port can be connected, so that the bar material inside the inner box can fall through the material discharge port. When the force applied to the material blocking plate is released, the return spring resets and can drive the material blocking plate away from the fixed plate, so that the material blocking plate can block the material discharge port, thus preventing the bar material inside the inner box from falling through the material discharge port.

[0027] Optionally, the material box opening and closing assembly includes:

[0028] A support frame is fixedly installed on one of the long sides of the material box positioning assembly;

[0029] A translation plate, which is slidably mounted on a support frame, wherein the translation direction of the translation plate is set along the width direction of the material box positioning assembly;

[0030] The first translation cylinder is mounted on the support frame and is used to drive the translation plate to move.

[0031] A toggle element is mounted slidably on a translation plate, and the translation direction of the toggle element is set along the length direction of the material box positioning assembly;

[0032] And a second translation cylinder, which is mounted on the translation plate and is used to drive the actuating component to translate;

[0033] When the material box is fixed by the material box positioning component, the waist-shaped groove is located on the moving path of the actuating component.

[0034] By adopting the above technical solution, when the material box is fixed on the material box positioning component, the second translation cylinder drives the actuating component to translate, so that the actuating block can be aligned with the waist-shaped groove set on the material box. Then, the first translation drive drives the translation plate to translate, so that the actuating block can pass through the waist-shaped groove into the outer shell of the material box. Finally, the second translation cylinder drives the actuating component to translate in a direction away from the material outlet, thus achieving the effect of automatically actuating the baffle plate.

[0035] Optionally, the material box positioning assembly includes:

[0036] A support plate, which is liftably mounted on the frame, and is provided with several guide wheels;

[0037] A lifting cylinder is mounted on the frame and located below the support plate. The lifting cylinder is used to drive the support plate to lift.

[0038] A push plate is slidably mounted on one of the long sides of a support plate, and the direction of translation of the push plate is set along the width direction of the support plate.

[0039] A side baffle is fixedly mounted on the long side of the support plate away from the push plate.

[0040] And a horizontal push cylinder, which is mounted on a support plate and is used to push the push plate to move horizontally;

[0041] When the material box moves to the support plate, the material box is located between the push plate and the side baffle.

[0042] By adopting the above technical solution, the guide wheel can reduce friction and facilitate manual pushing of the material box along the length of the support plate. When the material box moves above the support plate, the translation cylinder drives the push plate to move towards the side baffle, so that the push plate can push the material box to move towards the side baffle at the same time. This allows the push plate and the side baffle to cooperate with each other to clamp and fix the material box, thereby achieving the clamping and positioning of the material box.

[0043] Optionally, the material separating assembly includes:

[0044] A gantry frame, which is fixed to the machine frame and located at the end of the material box positioning assembly;

[0045] A buffer roller is rotatably mounted on the upper end of the gantry frame, extending beyond the side of the gantry frame near the material box positioning assembly.

[0046] A material receiving platform is fixedly installed inside the lower end of the gantry frame. One end of the material receiving platform is located directly below the material box discharge port, and the other end of the material receiving platform is connected to the feed end of the equipment.

[0047] And a material feeding mechanism, which is installed inside the frame. The output end of the material feeding mechanism passes through the side of the material receiving platform near the material box positioning component. The output end of the material feeding mechanism can move back and forth in the direction of approaching or moving away from the material box positioning component.

[0048] By adopting the above technical solution, when the material box approaches the feeding assembly, the upper end of the material box abuts against the outer wall of the buffer roller, which can realize the horizontal positioning of the material box along the length of the frame. When the bar material inside the material box falls onto the receiving platform, the feeding mechanism pushes the bar material on the receiving platform toward the equipment to realize the automatic feeding of the bar material.

[0049] Optionally, the material separating assembly further includes:

[0050] A gripper cylinder is installed at the lower end of the gantry frame, and the gripper cylinder is located above the side of the material receiving platform away from the material box positioning assembly.

[0051] When the bar stock moves to the side of the support platform near the equipment, the bar stock is located between the two grippers of the gripper cylinder.

[0052] By adopting the above technical solution, the two jaws of the gripper cylinder can clamp and position the two ends of the bar stock, thereby achieving horizontal positioning of the bar stock along its own length.

[0053] Optionally, it also includes a trolley and a trolley positioning component, the trolley positioning component comprising:

[0054] A support frame is slidably mounted on the feed end of the frame, and the sliding direction of the support frame is set along the width direction of the frame;

[0055] A translation mechanism, which is mounted on the frame, is used to drive the support frame to translate.

[0056] And a clamping mechanism, which is mounted on the support frame and is used to clamp and fix the trolley to the support frame;

[0057] The support frame includes a connecting part and a supporting part. The connecting part is slidably mounted on the frame, and the supporting part is located at the lower end of the connecting part. When the trolley is connected to the support frame, the trolley is located at the supporting part.

[0058] By adopting the above technical solution, when the trolley needs to be connected to the frame, the trolley is pushed onto the support frame, and then the trolley is brought into contact with the side of the connecting part away from the frame. Then, the clamping mechanism is used to clamp the trolley onto the support frame, so that the trolley can be stably connected to the support frame. Then, the translation mechanism is used to drive the trolley to translate and adjust its position, so that multiple material boxes can be placed on the trolley. Then, the corresponding material box is selected for loading, avoiding frequent transportation of material boxes.

[0059] Optionally, the clamping mechanism includes:

[0060] A drive cylinder, comprising several components, is provided, with each drive cylinder evenly distributed on the two long sides of the connecting portion, and the drive cylinder is configured as a rotary clamping cylinder.

[0061] A pressure rod, one end of which is fixedly connected to the piston rod of the drive cylinder, and the other end of the pressure rod, near the frame, can be connected to a trolley.

[0062] By adopting the above technical solution, when the trolley rests against the connecting part, the end of the pressure rod driven by the drive cylinder is displaced, so that the end of the pressure rod away from the drive cylinder can exert force on the trolley in the direction of the frame, thereby achieving the effect of clamping and fixing the trolley on the support frame.

[0063] In summary, this application includes at least one of the following beneficial technical effects:

[0064] 1. It can achieve automatic and precise feeding of bar stock, effectively improving production efficiency while reducing labor costs;

[0065] 2. The replenishment cycle of bar stock can be extended, avoiding frequent replenishment of bar stock by staff and further reducing the workload of staff. Attached Figure Description

The trolley 2 is detachably mounted on the trolley positioning assembly 3 and is used to transfer the material box 4. The material box 4 can be transferred between the trolley 2 and the frame 1. The material box positioning assembly 5 is used to fix the material box 4 on the frame 1. The material box opening and closing assembly 6 is used to open the lower end of the material box 4 so that the bar stock inside the material box 4 can fall out of the material box 4 under the action of gravity. The material distribution assembly 7 is used to push the bar stock falling from the material box 4 into the equipment.

[0087] Reference Figure 2 and Figure 3The trolley 2 mainly includes a body 21, a handle 22, a first guide wheel mechanism 23, and a quick clamp 24. The body 21 is a frame structure composed of several profiles. The upper end of the body 21 has a panel.

Several quick clamps 24 are provided, and each quick clamp 24 is evenly distributed on one side of each group of first guide wheel mechanisms 23.

[0088] When the trolley 2 is needed to transport the material box 4, first place the material box 4 on the corresponding first guide wheel mechanism 23, then push the trolley 2 closer to the frame 1, and finally push the material box 4 from the trolley 2 onto the frame 1. During the movement of the trolley 2, to ensure that the material box 4 remains stable, the quick clamp 24 is used to clamp and fix the material box 4 on the first guide wheel mechanism 23; wherein, refer to Figure 3 A base plate 41 is provided at the bottom of the material box 4. The base plate 41 extends out of the material box 4. The material box 4 is connected to the guide wheel mechanism through the base plate 41. A pad 211 is provided on the trolley 2. A quick clamp 24 is installed on the pad 211, so that the clamping end of the quick clamp 24 can be higher than the base plate 41, thereby enabling the quick clamp 24 to apply clamping force to the part of the base plate 41 that extends out of the bottom of the material box 4.

[0089] Reference Figure 4 A second guide wheel mechanism 11 is provided on the frame 1. Several groups of the second guide wheel mechanism 11 are arranged side by side along the width direction of the frame 1. Each group of the second guide wheel mechanism 11 includes several guide wheels arranged along the length direction of the guide wheel mechanism.

[0090] Reference Figure 1 and Figure 4 The trolley positioning assembly 3 includes a support frame 31, a clamping mechanism 33, and a translation mechanism 32. The support frame 31 is slidably mounted on the feed end of the frame 1, and the sliding direction of the support frame 31 is set along the width direction of the frame 1. The translation mechanism 32 is mounted on the frame 1 to drive the support frame 31 to adjust its horizontal position along the width direction of the frame 1. The clamping mechanism 33 is mounted on the support frame 31 to fix the trolley 2 to the support frame 31.

[0091] The translation mechanism 32 is a lead screw adjustment mechanism for a motor 747. The lead screw structure of the translation mechanism 32 is threadedly connected to the support frame 31, so that the translation mechanism 32 can drive the support frame 31 to move when it is running. Multiple material boxes 4 can be placed on the trolley 2 at the same time. Then, the position of the trolley 2 can be adjusted by using the translation mechanism 32, so that the person in charge can selectively replenish the material boxes 4.

[0092] Reference Figure 5 The support frame 31 includes a connecting part 311 and a supporting part 312. The connecting part 311 is slidably mounted on the frame 1 and is located at the lower end of the supporting part 312. A guide slope is provided on the side of the supporting part 312 away from the connecting part 311. Side plates 313 are provided on one opposite side of the supporting part 312. A plurality of limiting plates 314 are provided on the side of the connecting part 311 away from the frame 1. The limiting plates 314 are evenly distributed on the side of the supporting part 311 away from the frame 1. On the two vertical sides of the connecting part 311, the end of each limiting plate 314 away from the connecting part 311 is bent in a direction away from the center of the connecting part 311. When the trolley 2 needs to dock with the frame 1, the trolley 2 is pushed onto the support part 312, so that the trolley 2 abuts against the side of the connecting part 311 away from the frame 1. When the trolley 2 approaches the connecting part 311, the trolley 2 will make a slight adjustment in horizontal position under the guidance of each limiting plate 314.

In this embodiment, the drive cylinder 331 is a rotary clamping cylinder. The cylinder body of the drive cylinder 331 is fixed on the side of the support frame 31 away from the machine frame 1. The piston rod of the drive cylinder 331 is oriented away from the machine frame 1. When the trolley 2 rests against the connecting part 311, the drive cylinder 331 drives one end of the pressure rod 332 to move, so that the end of the pressure rod 332 away from the drive cylinder 331 can exert force on the trolley 2 in the direction of the connecting part 311, thereby achieving the effect of fixing the trolley 2 on the support frame 31.

[0094] Reference Figure 6 and Figure 7The material box 4 includes an outer shell 42, an inner box 43, and a baffle mechanism 44. The upper end of the outer shell 42 is open and is mounted on a base plate 41. A discharge port communicating with the interior of the outer shell 42 is provided on the base plate 41. The discharge port is located on one of the short sides of the base plate 41 and can only allow one bar to pass through. The inner box 43 is detachably installed inside the outer shell 42. One of the long sides of the inner box 43 is open and the lower end of the inner box 43 has a discharge port. When the inner box 43 is installed inside the outer shell 42, the discharge port of the inner box 43 communicates with the discharge port of the base plate 41. The baffle is slidably installed inside the lower end of the inner box 43. The baffle mechanism 44 is used to separate the discharge port and the discharge port so that the bar inside the inner box 43 cannot fall under the action of gravity.

[0095] When the inner box 43 is placed horizontally, the open side of the inner box 43 faces upward. At this time, the workers can place each bar vertically inside the inner box 43 and then install the inner box 43 into the outer shell 42. When the material box 4 is erected, each bar inside the inner box 43 is in a horizontal state, and the axial direction of each bar is set along the width direction of the inner box 43.

The upper end of the guide plate 431 is connected to one of the short side walls of the inner box 43, and the lower end of the guide plate 431 is close to the bottom of the inner box 43 and is located near the discharge port. When the inner box 43 is placed vertically, the bar material at the bottom of the inner box 43 can slide down along the inclined direction of the guide plate 431, so that the bar material at the bottom of the inner box 43 can fall through the discharge port of the inner box 43.

[0097] Reference Figure 8 The material blocking mechanism 44 includes a fixed plate 441, a baffle plate 442, a guide rod 443, and a return spring 444. The upper and lower ends of the fixed plate 441 are fixedly connected to the bottom surface of the guide plate 431 and the bottom of the inner box 43, respectively. The baffle plate 442 is arranged in an "L" shape and is located below the guide plate 431. The baffle plate 442 is located on the side of the fixed plate 441 near the discharge port. The horizontal end of the baffle plate 442 is attached to the bottom of the inner box 43. The horizontal end of the baffle plate 442 can pass through the lower end of the guide plate 431 to block the discharge port. The vertical end of the baffle plate 442 is fixedly connected to the guide rod 443. The end of the guide rod 443 away from the baffle plate 442 passes through the fixed plate 441. The return spring 444 is sleeved on the guide rod 443 and its two ends abut against the fixed plate 441 and the baffle plate 442, respectively.

[0098] When the material blocking mechanism 44 is in use, by moving the material blocking plate 442 toward the direction closer to the fixed plate 441, the discharge port can be opened, allowing the bar stock inside the inner box 43 to fall through the discharge port; when the return spring 444 is reset, it can drive the material blocking plate to move away from the fixed plate 441, so that the material blocking plate can block the discharge port, thus preventing the bar stock inside the inner box 43 from falling through the discharge port; wherein, a waist-shaped groove 411 is provided on the side of the outer shell 42, and the material box opening and closing component 6 can extend into the outer shell 42 through the waist-shaped groove 411 to move the material blocking plate 442.

The second guide wheel mechanism 11 of each group is installed on each material box positioning component 5. The material box opening and closing components 6 are arranged in several groups, and each group of material box opening and closing components 6 is installed on each material box positioning component 5.

[0100] Reference Figure 10 and Figure 11 The material box positioning assembly 5 includes a support plate 51, a lifting cylinder 52, a side baffle 53, a horizontal pushing cylinder 54, and a push plate 55. The support plate 51 is mounted on the frame 1 in a height-adjustable manner. The second guide wheel mechanism 11 is mounted on the upper side of the support plate 51. The cylinder body of the lifting cylinder 52 is mounted on the frame 1, and the piston rod of the lifting cylinder 52 is fixedly connected to the bottom surface of the support plate 51, so that the lifting cylinder 52 can drive the support plate 51 to rise and fall. The side baffle 53 is located on one long side of the support plate 51, and the horizontal pushing cylinder 54 is located on the other long side of the support plate 51. The piston rod of the horizontal pushing cylinder 54 is positioned towards the side baffle 53, and the push plate 55 is fixedly connected to the piston rod of the horizontal pushing cylinder 54.

[0101] When the material box 4 moves above the support plate 51 via the second guide wheel mechanism 11, the push plate 55 is driven by the translation cylinder to move toward the side baffle 53, so that the push plate 55 can push the material box 4 to move toward the side baffle 53 in sync. Finally, the material box 4 can be clamped and fixed by the cooperation between the push plate 55 and the side baffle 53, thereby realizing the clamping and positioning of the material box 4.

[0102] Reference Figure 10 On both long sides of the bottom surface of the support plate 51, there are several lifting plates 511 arranged along the length of the support plate 51. On the frame 1, there are several connecting plates 12 that correspond one-to-one in number and position to each lifting plate 511. The lifting plates 511 and connecting plates 12 arranged opposite each other are parallel to each other, and the lifting plates 511 and connecting plates 12 arranged opposite each other are connected by slide rails and sliders to achieve directional sliding connection.

The material box opening and closing assembly 6 includes a support frame 61, a translation plate 62, a first translation cylinder 63, a toggle member 64, and a second translation cylinder 65. The support frame 61 is fixedly installed on the lifting plate 512. The translation plate 62 is movably installed on the support frame 61, and the direction of movement of the translation plate 62 is set along the length direction of the material box positioning assembly 5. The first translation cylinder 63 is installed on the support frame 61 to drive the translation plate 62 to move. The toggle member 64 is movably installed on the translation plate 62, and the direction of movement of the toggle member 64 is set along the width direction of the material box positioning assembly 5. The second translation cylinder 65 is installed on the translation plate 62 to drive the toggle member 64 to move.

[0105] Reference Figure 12 and Figure 14 One end of the translation plate 62 is fixedly connected to the piston rod of the first translation cylinder 63, and a mounting plate is vertically installed on the other end of the translation plate 62. The second translation cylinder 65 is fixedly installed on the upper end of the mounting plate. The actuating member 64 is arranged in an "L" shape when viewed from above, and the middle part of the actuating member 64 is slidably connected to the translation plate 62. One end of the actuating member 64 passes through the mounting plate. A first vertical plate is provided on the end of the actuating member 64 that passes through the mounting plate.

[0106] When the material box 4 is fixed on the material box positioning assembly 5, the second translation cylinder 65 drives the actuating member 64 to translate, so that the actuating block can be aligned with the waist-shaped groove 411 set on the material box 4. Then, the first translation drive drives the translation plate 62 to translate, so that the actuating block can move towards the material box 4 until the actuating block passes through the waist-shaped groove 411 and enters the outer shell 42 of the material box 4. Finally, the second translation cylinder 65 drives the actuating member 64 to translate again, and the actuating member 64 actuates the baffle plate 442 so that the material box 4's lower outlet is connected to the inner box 43.

[0107] Refer to 1 and Figure 15 The material distribution component 7 is located at the end of the material box positioning component 5. When the material box 4 is pushed onto the material box positioning component 5, the upper end of the material box 4 can abut against the upper end of the material distribution component 7, thereby achieving the positioning of the material box 4 along the length direction of the material box positioning component 5. Furthermore, when the material box 4 completes the horizontal positioning, the material drop port of the material box 4 is located directly above the feeding end of the material distribution component 7, so that the bar material falling from inside the material box 4 can directly fall into the feeding end of the material distribution component 7.

[0108] Reference Figure 15 and Figure 16 The material distribution assembly 7 includes a gantry frame 71, a buffer roller 72, a material receiving platform 73, a material distribution mechanism 74, and a gripper cylinder 75. The gantry frame 71 is fixed to the machine frame 1. The buffer roller 72 is rotatably mounted on the upper end of the gantry frame 71, extending beyond the side of the gantry frame 71 closest to the material box positioning assembly 5. When the material box 4 approaches the material distribution assembly 7, the upper end of the material box 4 abuts against the outer wall of the buffer roller 72, thereby positioning the material box 4. The material receiving platform 73 is fixedly installed inside the lower end of the gantry frame 71, with the end of the material receiving platform 73 furthest from the material box positioning assembly 5 connected to the feed end of the equipment. The feeding mechanism 74 is installed at the lower end of the gantry frame 71, and the feeding mechanism 74 is connected to the side of the receiving platform 73 near the material box positioning component 5. The part of the feeding mechanism 74 connected to the receiving platform 73 can move back and forth in the direction of approaching or moving away from the material box positioning component 5, thereby pushing the bar on the receiving platform 73 towards the equipment. The gripper cylinder 75 is installed at the lower end of the gantry frame 71, and the gripper cylinder 75 is located above the side of the receiving platform 73 away from the material box positioning component 5. The two grippers of the gripper cylinder 75 can clamp and position the two ends of the bar, thereby realizing the horizontal positioning of the bar along its own length.

[0109] Reference Figure 16 The material receiving platform 73 includes a water platform 731 and an inclined platform 732. The water platform 731 is installed on the frame 1. When the material box 4 is connected to the material distribution assembly 7, the water platform 731 is located directly below the material drop opening of the material box 4. The inclined platform 732 is located inside the lower end of the gantry frame 71 and is located directly below the gripper cylinder 75. The upper side of the inclined platform 732 is connected to the side of the water platform 731 away from the material distribution assembly 7, and the lower side of the inclined platform 732 is connected to the feed end of the equipment. When the material distribution rod moves to a position away from the material box 4, the material distribution rod is located directly below the material drop opening of the material box 4. When the material distribution rod moves toward the direction closer to the material box 4, the material distribution rod is located on the side of the material drop opening of the material box 4 away from the inclined platform 732.

[0110] Reference Figure 17 and Figure 18The feeding mechanism 74 includes a translation table 741, a lever 742, a cam drive 743, and an elastic reset member 744. The translation table 741 is movably mounted on the frame 1, and its translation direction is along the length of the material box positioning assembly 5. The translation table 741 is located directly below the horizontal platform 731. The lower end of the lever 742 is fixed to the translation table 741, and the upper end of the lever 742 passes through the translation table 741 and extends... Above the translation stage 741, a connecting rod 745 extending into the frame 1 is fixedly connected to the bottom surface of the translation stage 741. A bearing 746 is connected to the connecting rod 745. A cam drive 743 is located inside the frame 1. The cam drive 743 is used to apply a force toward the material box positioning assembly 5 to the bearing 746. An elastic reset member 744 is installed on the frame 1. The elastic reset member 744 is used to apply a force toward the feed end of the equipment to the translation stage 741.

[0111] The cam drive 743 includes a motor 747 and a cam 748. The motor 747 is fixed to the frame 1. The cam 748 is fixedly connected to the output shaft of the motor 747, and the outer wall of the cam 748 abuts against the outer wall of the bearing 746, so that the cam 748 can push the bearing 746 towards the material box positioning assembly 5 when it is driven. The elastic reset member 744 is a spring. The end of the spring away from the material box positioning assembly 5 is fixedly connected to the frame 1, and the end of the spring near the material box positioning assembly 5 is fixedly connected to the translation stage 741. When the translation stage 741 is pushed by the cam drive 743 and moves towards the material box positioning assembly 5, the spring is in a stretched state. When the cam drive 743 releases the thrust on the bearing 746, the spring can return to its original state by restoring the translation stage 741.

[0112] The implementation principle of this application embodiment is as follows:

[0113] In use, several bars are added to the material box 4, ensuring that the axes of each bar are parallel and horizontal. Then, several material boxes 4 are placed side by side on the trolley 2. The trolley 2 is connected to the frame 1 via the trolley positioning component 3. The horizontal position of the trolley 2 is then adjusted via the trolley positioning component 3, allowing the operator to selectively push the corresponding material box 4 onto the material box positioning component 5. The material box positioning component 5 is used to position the designated material box 4 horizontally. The material box opening and closing component 6 is used to control the material outlet at the bottom of the material box 4 to connect with the inside of the material box 4, allowing the bars inside the material box 4 to fall one by one onto the feeding end of the material distribution component 7 under the action of gravity. Finally, the material distribution component 7 pushes the fallen bars one by one into the equipment.
