Description

Technical Field

[0001] This invention relates to the field of pyrophyllite production technology, specifically to a pyrophyllite pressing and molding device. Background Technology

[0002] Pyrophyllite has the advantages of fine texture, soft and oily feel, good machinability, white powder, high oil absorption, and good covering power. Its uses are closely related to its properties. It is mainly used as a refractory material, ceramic material, and carving raw material; secondly, it is also used as a filler and carrier in rubber products, cosmetics, pesticides, etc.

[0003] Pyrophyllite blocks are widely used in industrial production due to their properties of pressure retention, pressure transmission, sealing, heat resistance, insulation, and good electrical insulation. Pyrophyllite blocks have a cuboid structure and are mainly composed of dolomite rings and pyrophyllite blocks. Pyrophyllite blocks are generally obtained by pressing pyrophyllite raw materials and dolomite rings into shape.

[0004] During the production stage, the pressed pyrophyllite blocks are usually removed manually from the mold by workers. The workers reach into the pressing point in the middle of the machine to remove the pressed parts. This process of manually removing the pyrophyllite blocks from the mold is not very safe in production and is prone to safety hazards. It is also laborious for workers to repeat this process, which reduces work efficiency, increases the risk of danger, and increases labor costs, which is not conducive to the production development of enterprises.

[0005] Therefore, it is necessary to design a pyrophyllite block pressing and molding device with a pushing function to overcome the shortcomings of the existing technology. Summary of the Invention

[0006] The purpose of this invention is to provide a pyrophyllite block pressing and molding device to solve the problems mentioned in the background art, which state that in the production stage, the pressed pyrophyllite blocks are generally manually removed from the mold by workers who reach their hands into the pressing point in the middle of the machine to remove the pressed parts. This process of manually removing the pyrophyllite blocks from the mold is unsafe in production, prone to safety hazards, and requires workers to repeat the process, which is laborious, reduces work efficiency, is dangerous, increases labor costs, and is detrimental to the production development of enterprises.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a pyrophyllite block pressing and molding device, comprising a main frame and a pushing component, wherein a first motor is provided on the left side of the main frame, a first transmission shaft is fixedly connected to the output end of the first motor, a transmission belt is sleeved on the outer wall of the first transmission shaft, and the pushing component for conveying the blocks is located at the end of the transmission belt away from the first transmission shaft.

[0008] The pushing assembly includes a second drive shaft, a second lead screw, a second slider, a first bearing, a push rod, a third slider, a second limiting rod, and a stop block. The second lead screw is fixedly connected to the outer wall of the second drive shaft, and the second slider is sleeved on the outer wall of the second lead screw. The second slider has first bearings on both sides, and the first bearings are rotatably connected to the second lead screw. The first bearings are fixedly connected to the outer wall of the main frame. The push rod is fixedly connected to the outer wall of the second slider, and the third slider is located at the end of the push rod away from the second slider. The second slider and the third slider are at the same horizontal height. The third slider has a second limiting rod in the middle, and the second limiting rod has stop blocks at both ends. The stop blocks are fixedly connected to the outer wall of the main frame.

[0009] Furthermore, a sliding assembly for controlling lifting motion is provided on the side of the first drive shaft away from the first motor. The sliding assembly includes a first lead screw, a first slider, a guide plate, and a track groove. The first slider is sleeved on the outer wall of the first lead screw, and the guide plate is provided on the outer wall of the first slider. The track groove is opened at the position corresponding to the first slider on the guide plate.

[0010] Furthermore, the sliding assembly also includes a limiting plate, a first limiting rod, and a limiting groove. The limiting plate is fixedly connected to the front side of the first slider, the first limiting rod is provided on the front side of the limiting plate, and the limiting groove is provided at the corresponding position of the limiting plate and the first limiting rod.

[0011] Furthermore, the sliding assembly also includes a first connecting rod and a sleeve. The first connecting rod is sleeved on the outer wall of the first limiting rod, and the first connecting rod is a hollow rod-shaped structure welded to a solid rod body. The first connecting rod has a T-shaped structure design, and a sleeve is provided on the outer wall of the first connecting rod. A connecting piece is fixedly connected to the rear side of the sleeve, and the sleeve is fixedly connected to the guide rail plate.

[0012] Furthermore, a mold is fixedly connected to one end of the first limiting rod away from the limiting plate, and a base plate is provided below the mold, with the base plate being fixedly connected to the main frame.

[0013] Furthermore, a hydraulic press is fixedly connected to the top of the inner wall of the main frame, and a hydraulic rod is provided at the output end of the hydraulic press. The hydraulic rod is arranged in the same vertical line as the mold.

[0014] Furthermore, the hydraulic press has a discharge hopper on its left side, and a feeding port is provided on the outer wall of the discharge hopper.

[0015] Furthermore, the discharge hopper is equipped with a spiral blade inside, and a second motor is provided on the left side of the discharge hopper, with the output end of the second motor fixedly connected to the spiral blade.

[0017] This invention provides a device for pressing and molding pyrophyllite blocks, which has the following beneficial effects:

[0018] 1. This invention drives a first motor to control the push rod of the pushing component to move horizontally left and right on the top surface of the substrate. After the hydraulic press finishes pressing the pyrophyllite blocks in the mold, the formed pyrophyllite blocks can be pushed to the discharge point. During this process, the first motor can also drive the sliding component, so that the mold is raised and lowered to complete the pushing process. This eliminates the need for workers to manually remove the pyrophyllite blocks from the mold during actual production, saving labor costs, improving production efficiency, and enhancing production safety.

[0019] 2. This invention uses a sliding component to control the lifting and lowering of the first limit rod to drive the lifting and lowering of the mold. In conjunction with the pressing work of the hydraulic press, after the hydraulic rod completes the pressing task, the hydraulic rod first lifts the mold and then lifts up. By controlling the time difference between the lifting and lowering of the mold and the lifting and lowering of the hydraulic rod, the problem of pyrophyllite blocks sticking to the mold after pressing is solved. At the same time, it also cooperates with the pushing component to push the material, improving work efficiency and saving time costs.

[0020] 3. By adding a spiral blade to the discharge hopper, the second motor drives the spiral blade to add material to the mold, which can realize automatic material addition during the pressing and molding of pyrophyllite blocks, eliminating the need for manual material addition to the mold, reducing labor costs, and indirectly improving production efficiency.

[0030] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 , Figure 4 and Figure 6 A pyrophyllite block pressing and molding device includes a main frame 1 and a pushing component 7. A first motor 2 is provided on the left side of the main frame 1. A first transmission shaft 3 is fixedly connected to the output end of the first motor 2. A transmission belt 6 is sleeved on the outer wall of the first transmission shaft 3. The pushing component 7 for conveying the blocks is located at the end of the transmission belt 6 away from the first transmission shaft 3.

[0032] The specific operation is as follows: First, drive the first motor 2 to rotate, which drives the first transmission shaft 3 to rotate, and drives the push component 7 to rotate through the transmission belt 6. Through a set of power mechanisms, the sliding component 4 and the push component 7 can be operated simultaneously.

[0033] Please see Figure 1-8As shown, the pushing component 7 includes a second drive shaft 701, a second lead screw 702, a second slider 703, a first bearing 704, a push rod 705, a third slider 706, a second limiting rod 707, and a stop block 708. The second drive shaft 701 is fixedly connected to the outer wall of the second lead screw 702. The second slider 703 is sleeved on the outer wall of the second lead screw 702. The second slider 703 is provided with first bearings 704 on both sides. The first bearings 704 are rotatably connected to the second lead screw 702. The first bearings 704 are fixedly connected to the outer wall of the main frame 1. The push rod 705 is fixedly connected to the outer wall of the second slider 703. The end of the push rod 705 away from the second slider 703 is provided with the third slider 706. The second slider 703 and the third slider 706 are at the same horizontal height. The third slider 706 is provided with the second limiting rod 707 in the middle. The second limiting rod 707 is provided with stop blocks 708 at both ends. The stop blocks 708 are fixedly connected to the outer wall of the main frame 1.

[0034] The specific operation is as follows: the first motor 2 is driven to rotate, which drives the first transmission shaft 3 to rotate. The transmission belt 6 drives the second transmission shaft 701 to rotate. At this time, the second lead screw 702, which is fixed to the second transmission shaft 701, also rotates inside the first bearing 704. That is, the second slider 703, which is sleeved on the outer wall of the second lead screw 702, moves horizontally left and right along the second lead screw 702. At this time, the push rod 705, which is fixed to the second lead screw 702, also moves accordingly. That is, after the hydraulic press 8 finishes pressing the pyrophyllite block in the mold 5, the mold 5 and the hydraulic rod 9 are raised, and the pyrophyllite block formed on the top surface of the substrate 17 is pushed to the left and right discharge points. This invention controls the push rod 705 to move horizontally left and right on the top surface of the substrate 17 by setting the push component 7, which can push the formed pyrophyllite block to the discharge point. This eliminates the need for workers to manually remove the pyrophyllite block from the mold 5 in actual production, saving labor costs, improving production efficiency, and enhancing production safety.

[0035] Among them, the third slider 706 and the second slider 703 are at the same horizontal height, the second limiting rod 707 and the second lead screw 702 are in corresponding positions, the stop block 708 limits the third slider 706, and the first bearing 704 limits the second slider 703.

[0036] Please see Figure 2 , Figure 3 , Figure 5 and Figure 7 The first drive shaft 3 is provided with a sliding assembly 4 for controlling the lifting motion on the side away from the first motor 2. The sliding assembly 4 includes a first lead screw 401, a first slider 402, a guide plate 403 and a track groove 404. The first slider 402 is sleeved on the outer wall of the first lead screw 401, and the guide plate 403 is provided on the outer wall of the first slider 402. The track groove 404 is opened at the corresponding position of the guide plate 403 and the first slider 402.

[0037] The specific operation is as follows: the first motor 2 drives the first transmission shaft 3 to rotate, and the first transmission shaft 3 drives the first lead screw 401 to rotate. At this time, the first slider 402, which is sleeved on the outer wall of the first lead screw 401, slides left and right in the track groove 404 inside the guide plate 403.

[0038] Please see Figure 5-7 As shown, the sliding assembly 4 also includes a limiting plate 405, a first limiting rod 406, and a limiting groove 407. The limiting plate 405 is fixedly connected to the front side of the first slider 402. The first limiting rod 406 is provided on the front side of the limiting plate 405. The limiting groove 407 is provided at the corresponding position of the limiting plate 405 and the first limiting rod 406. The sliding assembly 4 also includes a first connecting rod 408 and a sleeve 409. The first connecting rod 408 is sleeved on the outer wall of the first limiting rod 406. The first connecting rod 408 is a hollow rod structure welded to a solid rod body. The first connecting rod 408 has a T-shaped structure design. The sleeve 409 is provided on the outer wall of the first connecting rod 408. A connecting piece is fixedly connected to the rear side of the sleeve 409. The sleeve 409 is fixedly connected to the guide rail plate 403. A mold 5 is fixedly connected to the end of the first limiting rod 406 away from the limiting plate 405. A base plate 17 is provided below the mold 5. The base plate 17 is fixedly connected to the main frame 1.

[0039] The specific operation is as follows: the limiting plate 405, which is fixed to the first slider 402, also moves accordingly. At this time, the first limiting rod 406, under the action of the limiting groove 407, begins to perform intermittent lifting and lowering motion. The first connecting rod 408 and the sleeve 409 make the first limiting rod 406 vertically stable. At this time, the mold 5, which is fixed to the first limiting rod 406, also performs intermittent lifting and lowering motion. This invention controls the lifting and lowering of the mold 5 through the sliding component 4, and cooperates with the pressing work of the hydraulic press 8. The time difference between the lifting and lowering of the hydraulic rod 9 solves the problem of the pyrophyllite block sticking to the mold 5 after pressing and forming. It also cooperates with the pushing work of the pushing component 7, improving work efficiency and saving time costs.

[0040] When the mold 5 needs to be filled and pressed, the first limiting rod 406 drives the mold 5 to be pressed against the top surface of the substrate 17. After pressing, the mold 5 rises before the hydraulic rod 9. The limiting groove 407 on the outer wall of the limiting plate 405 is a parallelogram structure. When the first limiting rod 406 moves to the upper and lower track positions, it is in a stable state. When it moves to the left and right track grooves 404, it is in a lifting state. That is, the first limiting rod 406 makes intermittent lifting movements when it moves in the limiting groove 407.

[0041] The inner wall of the transmission belt 6 has a toothed structure design, and gears are set near the first transmission shaft 3, the second transmission shaft 701 and the corresponding position of the transmission belt 6. Therefore, the driving of the transmission belt 6 will cause the second transmission shaft 701 to drive synchronously.

[0042] Please see Figure 1 , Figure 2 and Figure 8 A hydraulic press 8 is fixedly connected to the top of the inner wall of the main frame 1. A hydraulic rod 9 is provided at the output end of the hydraulic press 8. The hydraulic rod 9 is arranged in the same vertical line as the mold 5. A discharge barrel 13 is provided on the left side of the hydraulic press 8. A feeding port 14 is opened on the outer wall of the discharge barrel 13. A spiral blade 12 is provided inside the discharge barrel 13. A second motor 11 is provided on the left side of the discharge barrel 13. The output end of the second motor 11 is fixedly connected to the spiral blade 12. An observation window 10 is opened on the outer wall of the main frame 1. A second connecting rod 16 is provided on the outer wall above the second motor 11. A discharge port 15 is opened on the side of the discharge barrel 13 away from the second motor 11.

[0043] The specific operation is as follows: First, open the feeding port 14 to add material into the discharge barrel 13. After this step is completed, drive the second motor 11 to rotate the spiral blade 12. At this time, the processed material inside the discharge barrel 13 is discharged from the discharge port 15 into the mold 5. After the material is added into the mold 5, the second motor 11 stops running. At this time, the hydraulic press 8 runs, and the hydraulic rod 9 presses the processed material inside the mold 5. After pressing and forming, the hydraulic rod 9 rises, and the pressed pyrophyllite block is sent away by the push rod 705. Then, this operation process is repeated. By adding the spiral blade 12 to the discharge barrel 13, automatic material addition can be achieved during the pressing and forming of the pyrophyllite block, eliminating the need for manual material addition to the mold 5, reducing labor costs, and indirectly improving production efficiency.

[0044] The second motor 11 and the discharge bucket 13 are respectively fixedly connected to the second connecting rod 16, and the centers of the second motor 11 and the discharge bucket 13 are at the same horizontal height, so that the staff can observe them through the observation window 10 throughout the production process.

[0045] The feeding port 14 of the discharge hopper 13 can be connected to an external feeding box to achieve uninterrupted material supply.

[0046] Working principle: First, the feeding port 14 is opened to fill the discharge barrel 13 with material. After this step, the second motor 11 is driven to rotate the spiral blade 12. At this time, the processed material inside the discharge barrel 13 is discharged from the discharge port 15 into the mold 5. After the material is filled into the mold 5, the second motor 11 stops running. At this time, the hydraulic press 8 runs, and the hydraulic rod 9 presses the processed material inside the mold 5. After pressing and forming, the hydraulic rod 9 rises, simultaneously driving the first motor 2 to rotate the first transmission shaft 3. The first transmission shaft 3 then drives the second motor 8 to rotate the spiral blade 12. When the lead screw 401 rotates, the first slider 402, which is sleeved on the outer wall of the first lead screw 401, slides left and right in the track groove 404 inside the guide plate 403. The limiting plate 405, which is fixed to the first slider 402, also moves accordingly. At this time, the first limiting rod 406, under the action of the limiting groove 407, begins to perform intermittent lifting and lowering motion. The first connecting rod 408 and the sleeve 409 make the first limiting rod 406 vertically stable. At this time, the mold 5, which is fixed to the first limiting rod 406, also performs intermittent lifting and lowering motion. Before the hydraulic rod 9 rises... The mold 5 first rises away from the surface of the substrate 17, driving the first motor 2 to rotate, and simultaneously driving the second transmission shaft 701 to rotate via the transmission belt 6. At this time, the second lead screw 702, which is fixed to the second transmission shaft 701, also rotates inside the first bearing 704. That is, the second slider 703, which is sleeved on the outer wall of the second lead screw 702, moves laterally along the second lead screw 702. At this time, the push rod 705, which is fixed to the second lead screw 702, also moves accordingly, and the third slider 706 is at the same horizontal height as the second slider 703. The limiting rod 707 and the second lead screw 702 are in corresponding positions. The stop block 708 limits the third slider 706, and the first bearing 704 limits the second slider 703. That is, after the hydraulic press 8 finishes pressing the pyrophyllite block in the mold 5, the push rod 705 pushes the pyrophyllite block formed on the top surface of the substrate 17 to the left and right discharge points. The subsequent production repeats the production process of first adding material to the mold 5, then pressing the pyrophyllite block into shape by the hydraulic press 8, then raising the mold 5, and finally pushing the material with the push rod 705.

[0047] This technical solution uses a push assembly 7 with a push rod 705, and a corresponding sliding assembly 4 to work together. Without using a simple mechanical structure, the pressing and automatic pushing of the workpiece can be completed, which effectively improves production efficiency and makes it more convenient to use.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
