Description

Technical Field

[0001] This invention belongs to the field of extruder technology, specifically an automatic feeding mechanism for a graphite rod extruder. Background Technology

[0002] Graphite is an allotrope of carbon, a gray-black, opaque solid with stable chemical properties, corrosion resistance, and minimal reaction with acids and alkalis. During processing, graphite is typically extruded into rods using an extruder. Current extruders generally use a spindle to compress graphite into rods. To obtain longer rods, the spindle needs to retract, allowing new graphite material to be added through the feed hopper. However, the feed hopper is usually directly connected to the extruder's interior. Therefore, operators must wait until the spindle is fully retracted to create feeding space before adding the graphite material to the hopper, preventing it from contacting the side of the spindle. This necessitates a manual feeding operation each time graphite is added, as automatic feeding is not possible, and improvements are needed. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides an automatic feeding mechanism for a graphite rod extruder, which solves the problem of needing to manually add feed.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding mechanism for a graphite rod extruder, comprising...

[0007] The material control mechanism includes a feeding hopper, the bottom of which is fixedly connected to the top of the extruder housing. A cavity is provided in the lower part of the inside of the feeding hopper, and a material control plate is movably sleeved on the right end of the cavity. A circular hole is provided inside the material control plate, and the diameter of the feeding port is the same as that of the circular hole.

[0008] The moving mechanism is located below the control plate;

[0009] The thrust assembly is located inside the moving mechanism.

[0010] Preferably, the moving mechanism includes a slot, a mounting box, a movable block, and a locking block.

[0011] The slot is opened at the top of the main shaft. The mounting box is fixedly connected to the control plate. The inside of the mounting box is movably connected to the outside of the movable block. The bottom of the movable block is fixedly connected to the top of the locking block. The mounting box can move to the left, and the locking block can move upward.

[0012] Preferably, the thrust assembly includes a flexible spring, a groove, and a movable rod.

[0013] One end of the flexible spring is fixedly connected to the movable block, and the other end of the flexible spring is fixedly connected to the inner wall of the mounting box. The groove is opened inside the extruder housing. The movable rod is fixedly connected to the locking block. The flexible spring is in a compressed state, and the movable rod can move inside the groove.

[0014] Preferably, it further includes a lifting mechanism, which is disposed above the moving mechanism, and the lifting mechanism includes a fixed plate and a support plate.

[0015] The fixing plate is fixedly installed on the back of the feed hopper, and the fixing plate is movably connected to the support plate, allowing the support plate to slide upward on the back of the feed hopper.

[0016] Preferably, it further includes a transmission mechanism, which is disposed behind the material control plate. The transmission mechanism includes a round rod and a connecting shaft.

[0017] The round rod is fixedly connected to the control plate, the round rod is hinged to the connecting shaft, the connecting shaft is hinged to the support plate, and the round rod can move to the left.

[0018] Preferably, it further includes a discharge mechanism, which is disposed above the main shaft. The discharge mechanism includes a drive motor, a rotating shaft, and a spiral blade.

[0019] The drive motor is mounted on the top of the support plate. The output shaft of the drive motor is fixedly connected to the rotating shaft. The outside of the rotating shaft is fixedly connected to the inside of the spiral blade, and the rotating shaft can rotate.

[0020] Preferably, the left and right ends of the feed hopper are both fixedly connected to a fixing rod, and there are four fixing rods in total. The four fixing rods are arranged in pairs, and a movable plate is movably sleeved on the outside of each pair of fixing rods.

[0021] Preferably, it further includes an impact assembly disposed outside the feed hopper, the impact assembly comprising a rigid spring and an impact block.

[0022] One end of the rigid spring is fixedly connected to the feed hopper, and the other end of the rigid spring is fixedly connected to the moving plate. The impact block is fixedly connected to the moving plate, and the rigid spring is in a stretched state.

[0023] Preferably, it further includes a pushing mechanism disposed above the extruder housing, the pushing mechanism comprising a moving rod, a connecting plate, and a cam.

[0024] The moving rod is fixedly connected to the movable plate, and the moving rod is fixedly connected to the connecting plate. The inside of the cam is fixedly sleeved with the outside of the rotating shaft. The moving rod can move, and the cam can rotate.

[0025] Preferably, there are two moving rods, and the two moving rods are of different lengths, with the moving rod on the left being shorter than the moving rod on the right.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] This invention features a control plate, a circular hole, a slot, and a locking block. When the main shaft moves to the right, the bottom of the locking block can engage with the inside of the slot. Therefore, the movement of the main shaft can pull the control plate and the mounting box to the right, aligning the feed inlet with the circular hole. At this time, the graphite material inside the feed hopper can enter the extruder housing through the feed inlet and the circular hole, thus automatically feeding the material. Furthermore, the movement of the main shaft to the left can reset the feed inlet, preventing the graphite material from contacting the side of the main shaft.

[0028] This invention, by setting up a support plate, a connecting shaft, a drive motor, and a spiral blade, allows the support plate to move downwards when the control plate moves to the right via the connecting shaft. This enables the bottom of the spiral blade to move into the inside of the feed inlet. At this time, the operation of the drive motor will cause the spiral blade to rotate via the rotating shaft. The spiral blade can rotate and squeeze the graphite raw material inside the feed hopper into the inside of the extruder housing, thereby preventing the graphite raw material from clogging the feed inlet.

[0029] This invention incorporates a rigid spring, an impact block, a connecting plate, and a cam. When the shaft rotates, the cam rotates, causing the two connecting plates to lose the thrust of the cam. As a result, the rigid spring, which is in a stretched state, pulls the plates in opposite directions, causing the impact block to strike the feed hopper. As the cam rotates, it pushes the two connecting plates back to back, allowing the impact block to repeatedly strike the side of the feed hopper, causing it to vibrate. This makes it easier for the graphite raw material to enter the extruder housing. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 7 As shown, the present invention provides an automatic feeding mechanism for a graphite rod extruder, including an extruder housing 1, and a main shaft 2 is disposed inside the extruder housing 1;

[0040] Feed inlet 3 is located at the top of the extruder housing 1;

[0041] The material control mechanism includes a feeding hopper 4, the bottom of which is fixedly connected to the top of the extruder housing 1. A cavity 5 is provided in the lower part of the inside of the feeding hopper 4. A material control plate 6 is movably sleeved on the right end of the cavity 5. A round hole 7 is provided inside the material control plate 6. The diameter of the feeding port 3 is the same as that of the round hole 7.

[0042] The moving mechanism is located below the material control plate 6;

[0043] The thrust assembly is located inside the moving mechanism.

[0044] By adopting the above scheme and through the design of the material control mechanism, when the main shaft 2 moves to the right, the feeding operation can be carried out. At this time, the movement of the main shaft 2 can drive the material control plate 6 to move to the right through the moving mechanism, so that the feed port 3 and the round hole 7 are aligned. The material control plate 6 will release the obstruction effect on the graphite raw material, so that the graphite raw material can enter the interior of the extruder housing 1 through the feed port 3 and the round hole 7.

[0045] like Figure 3 and Figure 4 As shown, the moving mechanism includes a slot 8, a mounting box 9, a movable block 10, and a locking block 11.

[0046] The slot 8 is opened on the top of the main shaft 2. The mounting box 9 is fixedly connected to the control plate 6. The inside of the mounting box 9 is movably connected to the outside of the movable block 10. The bottom of the movable block 10 is fixedly connected to the top of the locking block 11. The mounting box 9 can move to the left, and the locking block 11 can move upward.

[0047] Using the above scheme, through the design of the moving mechanism, when the main shaft 2 moves to the right, the locking block 11 can move downward, so that its bottom end can be locked into the inside of the slot 8. At this time, the movement of the main shaft 2 will pull the control plate 6 and the mounting box 9 to the right through the locking block 11, so that the graphite raw material inside the feed hopper 4 can be added into the inside of the extruder housing 1. When the main shaft 2 moves to the rightmost end, the mounting box 9 will also move to the rightmost end.

[0048] like Figure 3 and Figure 4 As shown, the thrust assembly includes a flexible spring 12, a groove 27, and a movable rod 28.

[0049] One end of the flexible spring 12 is fixedly connected to the movable block 10, and the other end of the flexible spring 12 is fixedly connected to the inner wall of the mounting box 9. The groove 27 is opened inside the extruder housing 1. The movable rod 28 is fixedly connected to the locking block 11. The flexible spring 12 is in a compressed state, and the movable rod 28 can move inside the groove 27.

[0050] Using the above scheme, through the design of the thrust assembly, the flexible spring 12 can push the movable block 10, making it easier for the movable block 10 and the locking block 11 to move downwards. The groove 27 can limit the movable rod 28, preventing the movable rod 28 from moving upwards. Thus, when the main shaft 2 moves to the left, the locking block 11 can make the control plate 6 and the mounting box 9 move to the left.

[0051] like Figure 7 As shown, it also includes a lifting mechanism, which is located above the moving mechanism. The lifting mechanism includes a fixed plate 13 and a support plate 14.

[0052] The fixing plate 13 is fixedly installed on the back of the feed hopper 4. The fixing plate 13 is movably connected to the support plate 14, and the support plate 14 can slide upward on the back of the feed hopper 4.

[0053] By adopting the above scheme, through the design of the lifting mechanism, the fixed plate 13 can limit the support plate 14, so that the support plate 14 can only move upward or downward. The movement of the support plate 14 can prevent the rotating shaft 18 and the spiral blade 19 from interfering with the movement of the control plate 6, and can discharge the graphite raw material into the interior of the extruder housing 1 to prevent it from being blocked.

[0054] like Figure 5 As shown, it also includes a transmission mechanism, which is located behind the material control plate 6. The transmission mechanism includes a round rod 15 and a connecting shaft 16.

[0055] The round rod 15 is fixedly connected to the control plate 6, the round rod 15 is hinged to the connecting shaft 16, the connecting shaft 16 is hinged to the support plate 14, and the round rod 15 can move to the left.

[0056] Using the above scheme, through the design of the transmission mechanism, when the control plate 6 moves to the left, the flexible spring 12 will move to the left, and the movement of the round rod 15 can push the support plate 14 to move upward through the connecting shaft 16. When the control plate 6 moves to the right, the support plate 14 will move downward.

[0057] like Figure 4 As shown, it also includes a discharge mechanism, which is located above the main shaft 2. The discharge mechanism includes a drive motor 17, a rotating shaft 18, and a spiral blade 19.

[0058] The drive motor 17 is mounted on the top of the support plate 14. The output shaft of the drive motor 17 is fixedly connected to the rotating shaft 18. The outside of the rotating shaft 18 is fixedly connected to the inside of the spiral blade 19, and the rotating shaft 18 can rotate.

[0059] By adopting the above scheme, through the design of the discharge mechanism, when the drive motor 17 is running, the spiral blade 19 will rotate through the rotating shaft 18. The spiral blade 19 can rotate and squeeze the graphite raw material inside the feed hopper 4 into the extruder housing 1, thereby preventing the graphite raw material from blocking the feed port 3.

[0060] like Figure 4 As shown, the left and right ends of the feed hopper 4 are both fixedly connected with four fixing rods 20. The four fixing rods 20 are arranged in two groups, and each group of fixing rods 20 is movably sleeved with a movable plate 21.

[0061] By adopting the above scheme, through the design of the fixed rod 20 and the movable plate 21, the fixed rod 20 can limit the movable plate 21, so that the two movable plates 21 can only move to the left or right. When the movable plate 21 moves, it can cause the feed hopper 4 to vibrate.

[0062] like Figure 4 and Figure 6 As shown, it also includes an impact assembly, which is disposed outside the feed hopper 4. The impact assembly includes a rigid spring 22 and an impact block 23.

[0063] One end of the rigid spring 22 is fixedly connected to the feed hopper 4, and the other end of the rigid spring 22 is fixedly connected to the moving plate 21. The impact block 23 is fixedly connected to the moving plate 21, and the rigid spring 22 is in a stretched state.

[0064] Using the above scheme, through the design of the impact component, the rigid spring 22 can pull the moving plate 21, so that the two moving plates 21 can move towards each other, thereby allowing the impact block 23 to impact the side of the feed hopper 4, causing the feed hopper 4 to vibrate, thereby making the graphite raw material inside the feed hopper 4 move and more easily enter the interior of the extruder housing 1.

[0065] like Figure 4 As shown, it also includes a pushing mechanism, which is located above the extruder housing 1. The pushing mechanism includes a moving rod 24, a connecting plate 25, and a cam 26.

[0066] The moving rod 24 is fixedly connected to the moving plate 21, and the moving rod 24 is fixedly connected to the connecting plate 25. The inside of the cam 26 is fixedly sleeved with the outside of the rotating shaft 18. The moving rod 24 can move, and the cam 26 can rotate.

[0067] By adopting the above scheme and through the design of the pushing mechanism, when the rotating shaft 18 rotates, the cam 26 can rotate. At this time, the two connecting plates 25 will lose the thrust of the cam 26 and can be pulled by the rigid spring 22 to move in opposite directions. As the cam 26 rotates, the cam 26 can push the two connecting plates 25 to move in opposite directions again. The design of the connecting plates 25 enables the cam 26 to push the two connecting plates 25 to move in opposite directions when it moves downward.

[0068] like Figure 1 As shown, there are two moving rods 24, and the two moving rods 24 are of different lengths, with the left moving rod 24 being shorter than the right moving rod 24.

[0069] By adopting the above scheme, the design of the moving rod 24 allows the moving plate 21 and the connecting plate 25 to be integrated as a whole, so that the impact block 23 can reciprocate left and right to impact the feed hopper 4 and make it vibrate.

[0070] Working principle and usage process of this invention:

[0071] First, the operator can add graphite raw material into the feed hopper 4. When graphite raw material needs to be added into the extruder housing 1, the main shaft 2 will move to the right. At this time, the flexible spring 12 can push the movable block 10 downward, so that the bottom end of the locking block 11 is locked into the groove 8. At this time, the movement of the main shaft 2 will pull the control plate 6 and the mounting box 9 to the right through the locking block 11, and the movable rod 28 will move to the right inside the groove 27. The movement of the control plate 6 can make the feed port 3 and the round hole 7 aligned.

[0072] Afterwards, the movement of the control plate 6 can pull the support plate 14 downward through the connecting shaft 16, so that the bottom of the spiral blade 19 can move into the inside of the feed port 3, and the cam 26 can move between the two connecting plates 25. Then the operator can start the drive motor 17. The operation of the drive motor 17 will cause the spiral blade 19 and the cam 26 to rotate through the rotating shaft 18. The spiral blade 19 can rotate and squeeze the graphite raw material inside the feed hopper 4 into the inside of the extruder housing 1.

[0073] Then, the rotation of cam 26 will cause the two connecting plates 25 to lose thrust. At this time, the rigid spring 22 in the tension state will pull the two moving plates 21 to move towards each other, so that the impact block 23 will impact the feed hopper 4. As cam 26 rotates, cam 26 can push the two connecting plates 25 to move away from each other again, and the two moving plates 21 can move towards each other again. Therefore, the impact block 23 can repeatedly impact the side of the feed hopper 4, causing the feed hopper 4 to vibrate. When the main shaft 2 moves to the left after the feeding operation is completed, it will push the control plate 6 and the mounting box 9 to move to the left as a whole through the locking block 11. At this time, the support plate 14 will move upward until the control plate 6 moves to the leftmost end. The main shaft 2 continues to move and can push the locking block 11 upward, so that the movable rod 28 moves upward inside the groove 27, thereby preventing the control plate 6 from moving to the right.
