Description

Technical Field

[0001] The invention belongs to the technical field of material crushing, and in particular relates to a roller press with adjustable side baffles. Background Art

[0002] The roller press is a mechanical device that crushes products. During long-term use, it will produce obvious wear and tear, causing the thickness of key structures to be thinned, which will pose a great risk to the safe operation of the equipment. Among them, the side baffle of the high-pressure roller press is one of the structures that is most prone to wear; The side baffle is an important device to limit the material on both sides of the roller. It plays a vital role in reducing the leakage of materials on both sides, reducing the edge effect of the roller press, and improving the effective operation of the roller press. When the gap between the side baffle and the end face of the roller is small, the side baffle not only bears the scouring of the material, but also bears the outward squeezing force of the material between the rollers. Under such high stress wear conditions, the side baffle is very easy to wear, especially in the area with the smallest gap between the two rollers, where the wear is faster.

[0003] The side baffle is located between the two rollers. In order to crush the material, the distance between the rollers is small, which results in a small space for operators to operate when replacing the side baffles. Therefore, the replacement of the side baffles is mostly done when the rollers are repaired and disassembled, which results in untimely replacement of the side baffles and the easy leakage of materials at the worn side baffles. Therefore, the present application proposes a roller press with adjustable side baffles. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The roller press of the present invention includes two states: a side plate working state and a side plate replacement state. When the roller press is in the side plate replacement state, the worn inner side plate can be replaced. When replacing the worn inner side plate, the outer side plate is controlled by the displacement control unit to move to the side plate replacement area.

[0016] 2. The displacement control unit of the present invention can drive the inner plate to move and adjust the depth of the inner plate between the two rollers. When there is a lot of material, the inner plate can be moved away from the roller to reduce the pressure on the inner plate and extend the service life of the inner plate as much as possible.

[0017] 3. The side plate position locking assembly of the present invention can be stuck on the inner side of the feed frame after the inner side plate is inserted between the two rollers. At this time, the outer side plate is against the outer wall of the feed frame, so that the inner side plate cannot be moved at this time, and the upper end surface of the inner side plate is located directly below the outer wall of the feed frame. The feed frame can hinder the upward movement of the inner side plate, cooperate with each other, lock the position of the inner side plate, avoid the displacement of the inner side plate when it is squeezed by the material, and avoid the leakage of material during displacement.

[0033] Embodiment 2

[0034] Reference Figure 1-Figure 11 A roller press with adjustable side baffles, comprising a roller 1, a support device 2, an inner plate 3, an outer plate 4, a feed frame 5, and a side plate replacement bracket 9; a high-pressure roller press is a mechanical device for crushing products. During long-term use, it will produce obvious wear and tear, causing the thickness of key structures to be thinned, which will pose a great risk to the safe operation of the equipment. Among them, the side baffle (inner plate 3) of the high-pressure roller press is one of the structures that is most prone to wear; The side baffle (inner plate 3) is an important device for limiting the material on both sides of the roller. It plays a vital role in reducing the leakage of materials on both sides, reducing the edge effect of the roller press, and improving the effective operation of the roller press. When the gap between the side baffle (inner plate 3) and the end face of the roller is small, the side baffle (inner plate 3) not only bears the scouring of the material, but also bears the outward extrusion force of the material between the rollers. Under such high stress wear conditions, the side baffle (inner plate 3) is very easy to wear, especially in the area with the smallest gap between the two rollers, where the wear is faster.

[0035] Both rollers 1 are inserted into the supporting device 2. When the two rollers 1 are in the side plate working state, the inner plate 3 needs to be inserted between the two rollers 1, and the inner plate 3 is closer to the middle position of the roller 1 than the outer plate 4. The inner plate 3 directly contacts the material between the two rollers 1. The inner plate 3 is worn during use, while the outer plate 4 will not be directly worn. Therefore, only the inner plate 3 needs to be replaced.

[0036] It should be noted that the outer surface of the roller 1 is provided with a plurality of equally spaced mounting grooves, into which studs 101 are inserted. The studs 101 are made of hard alloy and can be used for a long time; In order to facilitate the assembly and disassembly between the inner panel 3 and the outer panel 4, a side panel combination rail 401 is provided on the outer panel 4, and a side panel combination groove is provided in the inner panel 3, the side panel combination groove cooperates with the side panel combination rail 401, and the side panel combination rail 401 and the side panel combination groove can only move up and down relative to each other. It should be mentioned that a bottom plate is provided at the bottom of the outer panel 4, and the bottom plate is used to prevent the inner panel 3 from moving further downward. It should be noted that since the gap between the two rollers 1 is generally large at the top and small at the bottom, the corresponding inner panel 3 needs to be set to a shape similar to the roller 1, so the side panel combination rail 401 includes three combination rails, two of the three combination rails are shorter and one is longer, and the longer one is located in the middle position of the outer panel 4, and the two shorter combination rails are located on both sides of the middle combination rail. This design can make the inner panel 3 and the outer panel 4 abut against each other in multiple directions, so that when the inner panel 3 is subjected to pressure, the pressure can be distributed to the outer panel 4.

[0037] The different speeds of the materials entering between the two rollers 1 and the different rotations between the two rollers 1 will lead to too much materials between the two rollers 1. The excessive materials will squeeze the inner plates 3 on both sides, which will cause greater damage to the inner plates 3. Therefore, a side plate displacement track 6 is provided on the feeding frame 5, and the outer plate 4 is slidably connected to the side plate displacement track 6, and the outer plate 4 is connected to a displacement control unit 7 for driving the outer plate 4 to move along the side plate displacement track 6. The side plate displacement track 6 is parallel to the roller 1, so that the inner plate 3 moves in a direction parallel to the roller 1, and the area between the two rollers 1 is the narrowest area between the roller 1 and the support device 2, and moves in a parallel direction, and will not touch other parts during the movement. The displacement control unit 7 can drive the inner plate 3 to move and adjust its depth of entry between the two rollers 1. When there is more material, the inner plate 3 is moved to the side away from the roller 1, which can reduce the pressure on the inner plate 3 and extend the service life of the inner plate 3 as much as possible.

[0038] When the two rollers 1 are working normally to crush materials, too much material will not be accumulated between the two rollers 1, so the inner plate 3 will not be squeezed too much. Therefore, the position of the inner plate 3 does not need to be adjusted at this time. In order to ensure the stability of the inner plate 3 when in use, the position of the inner plate 3 needs to be locked. Therefore, a side plate position locking component 8 is provided on the side of the inner plate 3 away from the side plate combination groove; The side plate position locking assembly 8 can be stuck on the inner side of the feed frame 5 after the inner side plate 3 is inserted between the two rollers 1, as shown in FIG. Figure 2 At this time, the outer plate 4 is against the outer wall of the feed frame 5, so the inner plate 3 cannot be moved at this time, and the upper end surface of the inner plate 3 is located directly below the outer wall of the feed frame 5, and the feed frame 5 can hinder the upward movement of the inner plate 3.

[0039] Specifically, refer to Figure 3-Figure 5 The side panel position locking assembly 8 includes a locking tongue 801 and a locking shell 802. The locking tongue 801 is inserted into the locking shell 802, and the locking tongue 801 and the locking shell 802 can only move relative to each other up and down. The bottom of the locking tongue 801 is connected to an upward push spring 807, and the upward push spring 807 can provide an upward elastic force, which is used to support the gravity of the locking tongue 801 and provide a force for the locking tongue 801 to move upward.

[0040] More specifically, a forward bevel 8011 is provided on the side of the lock tongue 801 away from the side plate combination groove, and a backward bevel 8012 is provided on the side of the lock tongue 801 close to the side plate combination groove. The height of the forward bevel 8011 in the vertical direction is higher than the height of the backward bevel 8012. The lock tongue 801 has a high-position locking state and a low-position passing state. When the lock tongue 801 is in the high-position locking state, the lowest height of the backward bevel 8012 is higher than the height of the lower end face of the feed frame 5, and the lowest height of the forward bevel 8011 is lower than the height of the lower end face of the feed frame 5. When the lock tongue 801 is in the low-position passing state, the lowest height of the backward bevel 8012 is lower than the height of the lower end face of the feed frame 5. In order to ensure that the lock tongue 801 can only move up and down, a guide plate 8013 is provided on the lock tongue 801, and the guide plate 8013 is connected to the lifting track in the locking shell 802. A guide groove 8014 is provided on one side of the lock tongue 801 parallel to the inner plate 3, and the guide groove 8014 is connected to the lifting frame 803. The lifting frame 803 includes a lifting shaft 8031 ​​and a transverse groove 8032. The lifting shaft 8031 ​​is plugged into the guide groove 8014, and the transverse groove 8032 is connected to the rotating plate 804. A connecting rod 8041 is installed at a non-center position on the rotating plate 804, and the connecting rod 8041 is inserted into the transverse groove 8032. It should be noted that a lifting slot is provided in the locking shell 802 , and the lifting frame 803 is inserted into the lifting slot. The height of the lifting slot is greater than the height of the guide slot 8014 , and the rotating plate 804 is connected to the driving motor 805 .

[0041] The driving motor 805 rotates, which can drive the rotating plate 804 to rotate. When the connecting rod 8041 on the rotating plate 804 moves along the transverse groove 8032 in the lifting frame 803, it will pull the lifting frame 803 to move up and down in the lifting groove. In this way, the lifting frame 803 can be driven to move up and down. When the lifting frame 803 moves, it will pull the lifting shaft 8031 ​​to move along the guide groove 8014. The height of the lifting groove is greater than the height of the guide groove 8014, so the lifting frame 803 descends. When it reaches the lowest height, it will squeeze the lock tongue 801, allowing the lock tongue 801 to fall, thereby converting the lock tongue 801 into a low-position passage state. At this time, the height of the lowest point of the retreating bevel 8012 is lower than the height of the lower end surface of the feed frame 5. When the displacement control unit 7 drives the outer plate 4 and the inner plate 3 to move, the thrust pulls the locking shell 802 to move, and the feed frame 5 squeezes the retreating bevel 8012, allowing the lock tongue 801 to be retracted into the locking shell 802, so that the inner plate 3 can move.

[0042] It should be noted that the two output shafts of the driving motor 805 are respectively connected to the rotating plate 804 and the locking plate 806, and the rotating plate 804 and the locking plate 806 are provided with a first material unloading locking groove 8042 and a second material unloading locking groove 8061. The first material unloading locking groove 8042 and the second material unloading locking groove 8061 are used to assist the unloading work of the inner plate 3; The side panel replacement bracket 9 is connected to an angle conversion unit 10 for driving the side panel replacement bracket 9 to rotate.

[0043] The roller press has a side panel working state and a side panel replacement state, and a side panel replacement area is provided in the roller press. When the roller press is in the side panel replacement state, the outer panel 4 is moved to the side panel replacement area via the control of the displacement control unit 7. Under the control of the angle conversion unit 10, the side panel replacement bracket 9 is vertically distributed, and the spare inner panel 19 on the side panel replacement bracket 9 and the inner panel 3 on the outer panel 4 are on the same plane.

[0044] Specifically, a lifting unit 11 is provided on the side plate replacement bracket 9, and the lifting unit 11 is connected to a displacement unit 12, and the lifting unit 11 is used to drive the displacement unit 12 to move up and down, and the displacement unit 12 is connected to a crossbeam 13, and the displacement unit 12 is used to drive the crossbeam 13 to move in a direction perpendicular to the roller 1; More specifically, a side panel replacement unit is provided on the crossbeam 13, and the side panel replacement unit moves together with the crossbeam 13. With the cooperation of the lifting unit 11 and the displacement unit 12, the side panel replacement unit is used to hook and release the worn inner panel 3 on the outer panel 4, and the worn inner panel 3 can be pulled out from the outer panel 4 from bottom to top in cooperation with the lifting unit 11 and the displacement unit 12; It should be noted that the side plate replacement unit includes a side plate replacement hook plate 14, and the side plate replacement hook plate 14 is provided with a hook material protrusion 1401 and a vertical rod. When the roller press is in the side plate replacement state, the side plate replacement hook plate 14 is aligned with the rotating plate 804 and the locking plate 806 in the side plate position locking assembly 8. The rotating plate 804 and the locking plate 806 have similar structures and are circular in overall design. The vertical rod and the rotating plate 804 do not interfere with each other, and the hook material protrusion 1401 can be hooked in the first material unloading locking groove 8042 in the rotating plate 804. Figure 7, the side panel replacement hook plate 14 moves downward to the locking plate 806, and the hook material protrusion 1401 is inserted into the second material removal locking groove 8061. At this time, the driving motor 805 drives the locking plate 806 to rotate, so that the second material removal locking groove 8061 in the locking plate 806 is pressed on the upper side of the hook material protrusion 1401, so that the two hook material protrusions 1401 respectively matched with the first material removal locking groove 8042 and the second material removal locking groove 8061 can hook the inner side plate 3. At this time, the lifting unit 11 drives it to move upward, and the inner side plate 3 can be hooked out from the outer side plate 4, that is, the side panel replacement hook plate 14 is used in conjunction with the side panel position locking assembly 8, and no additional power source is required for clamping and loosening the inner side plate 3; In a further embodiment, since the unloading locking groove is not located in the middle position of the inner plate 3, the inner plate 3 is easy to tilt when lifting, so a side plate unloading auxiliary track 18 is provided on the cross beam 13. When the roller press is in the side plate replacement state, the side plate unloading auxiliary track 18 is aligned up and down with the side plate combination groove in the inner plate 3.

[0045] In order to store the spare inner plate 19, a spare side plate storage plate 15 is provided on the cross beam 13, and the spare inner plate 19 is stored on the spare side plate storage plate 15. When the roller press is in the side plate replacement state, the spare inner plate 19 at the spare side plate storage plate 15 and the inner plate 3 on the outer plate 4 are on the same plane.

[0046] Specifically, a material unloading guide track is installed on the spare side panel storage plate 15. When the spare inner side panel 19 is located on the spare side panel storage plate 15, the height of the lowest point of the material unloading guide track is lower than the height of the spare inner side panel 19. The material unloading guide track and the spare inner side panel 19 can only move up and down relative to each other. Two blocking rods 16 are installed on the spare side panel storage plate 15. The two blocking rods 16 are respectively installed on two rotating disks 17. The rotating disk 17 is connected to a power unit for driving the rotating disk 17 to rotate. When the spare inner panel 19 is moved to the top of the outer panel 4 by the displacement unit 12, the lifting unit 11 is used to move it downward and align it with the outer panel 4, so that the spare inner panel 19 is partially inserted into the side panel combination track 401 in the outer panel 4, and then the rotating disk 17 is rotated to rotate the blocking rod 16 to a position that does not hinder the inner panel 3 from moving downward, so that the inner panel 3 falls into the outer panel 4, thus completing the replacement of the inner panel 3. At the same time, in order to allow the inner panel 3 to smoothly enter the outer panel 4, a corresponding pressing plate can also be provided on the side panel replacement bracket 9. When the roller press is in the side panel replacement state, the width of the pressing plate is greater than the width of the inner panel 3. The lifting unit 11 drives the pressing plate to move downward, and the pressing plate can be pressed into the outer panel 4. When the roller press is in the side plate working state, the lower end surface of the side plate replacement bracket 9 is pressed against the upper end surface of the shell of the supporting device 2.

[0047] As an alternative implementation, the side plate combined rail 401 may be an I-beam, and the side plate combined groove may be a connecting slide groove, which is slidably connected to the I-beam.

[0048] Working principle: The roller press includes two states: side plate working state and side plate replacement state. When the roller press is in the side plate working state, the inner side plate 3 is located between the two rollers 1 to prevent the material from leaking from the gap between the two rollers 1. When the roller press is in the side plate replacement state, the worn inner side plate 3 can be replaced.

[0049] When replacing the worn inner plate 3, the outer plate 4 is controlled by the displacement control unit 7 to move to the side plate replacement area. Under the control of the angle conversion unit 10, the side plate replacement bracket 9 is vertically distributed. Then, the side plate replacement hook plate 14 moves downward under the drive of the lifting unit 11, and the side plate replacement hook plate 14 moves to the locking plate 806, and the hooking protrusion 1401 is inserted into the second material removal locking groove 8061. At this time, the driving motor 805 drives the locking plate 806 to rotate, so that the second material removal locking groove 8061 in the locking plate 806 is pressed on the upper side of the hooking protrusion 1401, so that the two hooking protrusions 1401 respectively cooperating with the first material removal locking groove 8042 and the second material removal locking groove 8061 can hook the inner plate 3. At this time, the lifting unit 11 drives it to move upward, so that the inner plate 3 can be hooked out from the outer plate 4; Afterwards, the displacement unit 12 pulls the crossbeam 13 to move, and aligns the spare side panel storage plate 15 on the crossbeam 13 with the position of the outer panel 4. Then, the lifting unit 11 drives the crossbeam 13 to move downward, so that the spare inner panel 19 on the spare side panel storage plate 15 is aligned with the outer panel 4. Then, the rotating disk 17 is rotated to allow the spare inner panel 19 to move downward under the action of gravity, and finally the inner panel 3 falls onto the outer panel 4. Then, the replaced inner panel 3 is sent between the two rollers 1 through the displacement control unit 7, and the angle conversion unit 10 rotates the side panel replacement bracket 9 to the upper side of the support device 2.
