Description

Technical Field

[0001] This invention belongs to the field of material crushing technology, specifically relating to a roller press with side baffle wear detection function. Background Technology

[0002] Roller presses are mechanical devices used to crush products. During long-term use, they will experience significant wear, resulting in a reduction in the thickness of key structures, which poses a great risk to the safe operation of the equipment.

[0003] Chinese Patent CN 118287205 A discloses a retractable wear self-inspection side baffle for a roller press feeding device, which includes: a wear-resistant composite liner slidably fitted onto the outer periphery of a frame; a driving mechanism disposed within the cavity of the end-face sealing back plate, the driving mechanism being used to push the wear-resistant composite liner to move along the roller axis; and a detection module including a detection probe fixedly embedded on the side of the wear-resistant composite liner away from the driving mechanism; wherein, the driving mechanism, based on the wear amount detected by the detection module, drives the wear-resistant composite liner to move horizontally to fill the wear gap caused by wear.

[0004] However, the above-mentioned device has the following problems during use:

[0005] The drive mechanism can drive the wear-resistant composite liner to move horizontally to fill the wear gap caused by wear, so that the front of the wear-resistant composite liner is always blocked between the two rollers (equivalent to rollers). However, the side of the wear-resistant composite liner that is close to the rollers is also a major area of ​​wear. During the crushing process of the rollers, the material will squeeze the side of the wear-resistant composite liner. The side of the wear-resistant composite liner is prone to excessive gap between itself and the rollers due to wear, resulting in material leakage. Therefore, this application proposes a roller press with side baffle wear detection function. Summary of the Invention

[0006] The purpose of this invention is to provide a roller press with a side baffle wear detection function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a roller press with side baffle wear detection function, comprising a roller, a support device, an inner side plate, and an outer side plate;

[0008] The two ends of the roller are inserted into two support devices, and a working area is set between the two rollers;

[0009] The inner side plate is set on the outer side plate, and the inner side plate is located between the two rollers, with a gap between the inner side plate and the outer wall of the roller;

[0010] The inner side plate is provided with a side detection feeding unit, which includes two wear-resistant side plates. The two wear-resistant side plates are located on two sides of the inner side plate near the outer walls of the two rollers. The side detection feeding unit is used to detect the thickness of the wear-resistant side plates. After detecting that the thickness of the wear-resistant side plates has become thinner, the side detection feeding unit pushes the inner side plate to move closer to the rollers.

[0011] Preferably, it also includes a feeding frame and a track plate. The feeding frame is located above the working area and is set on the track plate. The track plate is set on the support device, and the outer plate is connected to a moving device for controlling the depth of the inner plate inserted between the two rollers.

[0012] Preferably, the side detection feed unit further includes a side detection module, and a side detector mounting slot is provided in the wear-resistant side plate. Multiple side detection modules are distributed and installed in the side detector mounting slot. The side detection module can be a thickness sensor.

[0013] Preferably, the wear-resistant side plate is connected to a side feeding device, which is used to push the wear-resistant side plate to move towards the side closer to the outer wall of the roller or away from the outer wall of the roller. The inner side plate is provided with a side groove, and the wear-resistant side plate is inserted into the side groove.

[0014] Preferably, the side detection module can also be an electromagnetic ultrasonic detection sensor, which is installed in the side detector mounting slot.

[0015] Preferably, the inner side plate is provided with a lower wear-resistant plate, an upper wear-resistant plate, and a replacement unit. Both the lower wear-resistant plate and the upper wear-resistant plate are provided with a front wall thickness detection module. Multiple front wall thickness detection modules are used to measure the wall thickness of the lower wear-resistant plate and the upper wear-resistant plate, respectively. When the front wall thickness detection module detects that the thickness of the lower wear-resistant plate is too thin, the replacement unit swaps the positions of the lower wear-resistant plate and the upper wear-resistant plate.

[0016] Preferably, the replacement unit includes a winding device, in which a connecting rope is provided. One end of the connecting rope is connected to the upper wear-resistant plate, and the other end of the connecting rope is connected to the inner frame.

[0017] Preferably, a first square frame and a second square frame are installed on the inner frame. A first square groove is provided in the first square frame, a first connecting rod is inserted in the first square groove, a first inclined plate is inserted into the first connecting rod, an intermediate shaft is inserted into the first inclined plate, a second inclined plate is inserted into the intermediate shaft, a second connecting rod is inserted into the top of the second inclined plate, the second connecting rod is inserted into the second square groove, the second square groove is located inside the second square frame, and the intermediate shaft is connected to a retraction power unit.

[0018] Preferably, a guide block is provided inside the upper wear-resistant plate, and a guide groove is provided inside the replacement unit, with the guide block and the guide groove cooperating.

[0019] Preferably, the inner frame is provided with a guide plate, the guide plate is connected to a slider, the slider is inserted into a guide rail, the guide rail is connected to an outer frame, and the guide groove is provided inside the outer frame.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] I. The side detection module of this invention can be an electromagnetic ultrasonic detection sensor. The electromagnetic ultrasonic detection sensor is installed in the side detector mounting slot. Multiple electromagnetic ultrasonic detection sensors can measure the wall thickness at multiple points on the wear-resistant side plate. Based on the measured data, the wear condition of the wear-resistant side plate is determined. If the wear exceeds the set value, the wear-resistant side plate can be moved closer to the outer wall of the roller through the side detection feeding unit, shortening the distance between the wear-resistant side plate and the outer wall of the roller. This allows the easily worn side to be compensated for distance according to the wear condition, extending the service life of the inner side plate.

[0022] Second, the retraction power unit in the replacement unit of this invention causes the lower wear-resistant plate to be converted to a retracted state. Then, the winding device is activated, and the connecting rope on it pulls the lower wear-resistant plate upward. The other end of the connecting rope is released, and the upper wear-resistant plate moves downward under the action of gravity. Finally, the upper wear-resistant plate falls to the original position of the lower wear-resistant plate. Then, the retraction power unit is activated, causing the lower wear-resistant plate to be converted to an unfolded state. At this time, the positions of the lower and upper wear-resistant plates are swapped. After the positions of the lower and upper wear-resistant plates are swapped, after a certain period of use, the overall wear degree of both is roughly the same. With the help of the moving device that can drive the lower and upper wear-resistant plates to move, the lower and upper wear-resistant plates can be kept in synchronous wear. In this way, the inner plate can be used for a longer period of time before replacement, which can extend the service life of the inner plate. Attached Figure Description

[0034] 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.

[0035] Reference Figures 1-3 A roller press with side baffle wear detection function includes a roller 1, a support device 2, a feeding frame 3, a track plate 4, an inner side plate 5, and an outer side plate 6.

[0036] The two ends of the roller 1 are inserted into the two support devices 2. A working area is set between the two rollers 1. The working area serves as the area for extruding materials. The two rollers 1 extrude materials in the working area to crush them. The feeding frame 3 is located above the working area and is set on the track plate 4. The track plate 4 is set on the support device 2.

[0037] The feeding frame 3 feeds the material into the components within the working area, causing the material to fall between the two rollers 1.

[0038] Reference Figure 4 , Figure 5 The inner side plate 5 is set on the outer side plate 6 and inserted between the two rollers 1. There is a gap between the inner side plate 5 and the outer wall of the roller 1. The gap is to avoid mutual wear between the inner side plate 5 and the rotating roller 1. The two inner side plates 5 are located on both sides of the working area to seal the working area and prevent the material from leaving the working area and thus being unable to be crushed by the roller 1.

[0039] The outer plate 6 is connected to a moving device 7 for controlling the depth of the inner plate 5 inserted between the two rollers 1. The moving device 7 can drive the outer plate 6 to move, thereby driving the inner plate 5 to move and adjusting the depth of the inner plate 5 inserted into the two rollers 1. This depth can be determined according to the amount of material entering the working area, so that the inner plate 5 can prevent the material from moving outward and allow the material to be crushed in the working area.

[0040] When the two rollers 1 crush the material, they compress the material. The compressed material wears against the inner side plate 5, causing the inner side plate 5 to thin and become unable to properly block the material. The areas where the inner side plate 5 is most prone to wear are usually on the side of the inner side plate 5 (i.e., the outer wall of the inner side plate 5 closest to the outer wall of the roller 1) and at the bottom area of ​​the front of the inner side plate 5 (i.e., the area where the distance between the two rollers 1 is narrowest, see reference). Figure 1 , Figure 3 (That is, the location of the lower wear-resistant plate 9.)

[0041] In order to detect the easily worn sides of the inner side plate 5 and to compensate for the worn sides of the inner side plate 5, a side detection feeding unit 8 is provided in the inner side plate 5. The side detection feeding unit 8 includes two wear-resistant side plates 801, which are located on two sides of the inner side plate 5 near the outer walls of the two rollers 1. The side detection feeding unit 8 is used to detect the thickness of the wear-resistant side plates 801. After detecting that the thickness of the wear-resistant side plates 801 has become thinner (due to wear with the material), the side detection feeding unit 8 pushes the inner side plate 5 to move closer to the rollers 1.

[0042] Specifically, the side detection feeding unit 8 also includes a side detection module 803, which can be a thickness sensor. The wear-resistant side plate 801 is provided with a side detector mounting slot 802, and multiple side detection modules 803 are distributed and installed in the side detector mounting slot 802. Specifically, the side detection module 803 can be an electromagnetic ultrasonic sensor, which is installed in the side detector mounting slot 802. Multiple electromagnetic ultrasonic sensors can measure the wall thickness at multiple points in the wear-resistant side plate 801. The electromagnetic ultrasonic sensor can withstand long-term online measurement at a high temperature of 100°C. Based on the measured data, the wear condition of the wear-resistant side plate 801 is judged. If the wear exceeds the set value, the side detection feeding unit 8 can push the wear-resistant side plate 801 to move closer to the outer wall of the roller 1, shortening the distance between the wear-resistant side plate 801 and the outer wall of the roller 1. At this time, the worn wear-resistant side plate 801 can still block the material in the working area.

[0043] Multiple electromagnetic ultrasonic testing sensors are connected to a four-channel thickness gauge. The four-channel thickness gauge processes and analyzes the data from the electromagnetic ultrasonic testing sensors to calculate the measured wall thickness. The four-channel thickness gauge is connected to the control system via RS485 and can be connected to a PLC. It can simultaneously upload thickness measurement and waveform data. The control system is equipped with a data server that displays the wall thickness and waveform results uploaded by the four-channel thickness gauge. The detection parameters of the thickness gauge can also be set via software to achieve accurate thickness measurement.

[0044] Electromagnetic ultrasonic testing devices mainly consist of three parts: a high-frequency coil, an external magnetic field, and the test specimen itself. Figure 4 As shown, when a high-frequency coil placed on the surface of a workpiece carries a high-frequency current, it generates eddy currents within the workpiece's skin layer. These eddy currents, under the influence of an external magnetic field, are subjected to mechanical force and produce high-frequency vibrations, forming an ultrasonic wave source. When receiving ultrasonic waves, the oscillations on the workpiece surface are also induced in the high-frequency coil under the influence of the external magnetic field, and are thus received by the instrument.

[0045] (1) The energy conversion of electromagnetic ultrasonic testing is carried out directly in the skin layer on the surface of the workpiece. Since the skin layer is the surface layer of the workpiece, the ultrasonic waves generated by electromagnetic ultrasonic testing do not require any coupling medium.

[0046] (2) Electromagnetic ultrasound does not require contact with the material in which the sound wave propagates to send and receive the returned ultrasonic waves. Therefore, no special cleaning is required for the surface of the workpiece being tested, and rougher surfaces can also be directly tested.

[0047] (3) One of the biggest advantages of electromagnetic ultrasound over conventional ultrasound is its non-contact nature. The temperature field of the heat body in space decays exponentially. As the probe moves away from the surface of the test piece, the ambient temperature of the probe drops significantly. Therefore, electromagnetic ultrasound can be used for the detection of high-temperature workpieces.

[0048] The vibration of the detection components over a long period of time may interfere with the detection data. The equipment filters out vibration interference from both the installation structure and the detection algorithm to ensure detection accuracy.

[0049] (1) Structural method: Set the sensor vibration filtering installation angle to reduce the impact of vibration.

[0050] (2) Algorithm: Through a professional filtering algorithm, noise interference caused by vibration is eliminated, the signal-to-noise ratio is improved, and the echo waveform is accurately identified.

[0051] (3) Thickness measurement data.

[0052] More specifically, the wear-resistant side plate 801 is connected to a side feeding device 804, which is used to push the wear-resistant side plate 801 to move towards the side closer to the outer wall of the roller 1 or away from the outer wall of the roller 1. In order to make the wear-resistant side plate 801 more stable when subjected to force, a side groove 501 is provided in the inner side plate 5, and the wear-resistant side plate 801 is inserted into the side groove 501.

[0053] Reference Figures 6-8 In order to inspect the narrowest area in the middle of the easily worn roller 1 and replace the worn lower wear plate 9 according to the inspection results, a lower wear plate 9, an upper wear plate 10, and a replacement unit 11 are provided on the inner side plate 5. The lower wear plate 9 is located in the area of ​​the narrowest distance between the two rollers 1.

[0054] Specifically, both the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are equipped with front wall thickness detection modules 12. Multiple front wall thickness detection modules 12 are used to measure the wall thickness of the lower wear-resistant plate 9 and the upper wear-resistant plate 10 respectively. Based on the wall thickness value, the thickness of the lower wear-resistant plate 9 and the upper wear-resistant plate 10 is determined. The front wall thickness detection module 12 can also use an electromagnetic ultrasonic detection sensor. The lower wear-resistant plate 9 is located in the area where the distance between the two rollers 1 is the narrowest. The lower wear-resistant plate 9 is worn much faster than the upper wear-resistant plate 10. When the front wall thickness detection module 12 detects that the thickness of the lower wear-resistant plate 9 is too thin (i.e., when the lower wear-resistant plate 9 is worn too much), the replacement unit 11 swaps the positions of the lower wear-resistant plate 9 and the upper wear-resistant plate 10. This causes the upper wear-resistant plate 10 to move to the area with the narrowest gap between the two rollers 1, while the lower wear-resistant plate 9 moves to the original position of the upper wear-resistant plate 10. In this way, the two wear-resistant plates share the work, making the wear degree of the upper and lower parts of the middle area of ​​the inner side plate 5 tend to be the same, so that the wear degree of the two wear-resistant plates tends to be the same. The two wear-resistant plates work separately in the severely worn area between the rollers 1, which extends the overall service life of the inner side plate 5. At the same time, after the two wear-resistant plates are worn, they can be moved to a deeper part of the working area by the moving device 7, and the material sealing work in the working area can still be carried out.

[0055] Specifically, the replacement unit 11 includes a winding device 1101, which is equipped with a connecting rope. One end of the connecting rope is connected to the upper wear-resistant plate 10, and the other end of the connecting rope is connected to the inner frame 1102. One end of the connecting rope moves downward and the other end moves upward.

[0056] More specifically, a first square frame 1103 and a second square frame are installed on the inner frame 1102. A first square groove is provided in the first square frame 1103. A first connecting rod is inserted in the first square groove. A first inclined plate 1104 is inserted into the first inclined plate 1104. An intermediate shaft 1106 is inserted into the first inclined plate 1104. A second inclined plate 1105 is inserted into the intermediate shaft 1106. A second connecting rod is inserted into the top of the second inclined plate 1105. The second connecting rod is inserted into a second square groove. The second square groove is located inside the second square frame. A retraction power unit 1107 is connected to the intermediate shaft 1106.

[0057] The retraction power unit 1107 can push the intermediate shaft 1106 to move up and down. When the intermediate shaft 1106 moves upward, the first inclined plate 1104 and the second inclined plate 1105 move around the intermediate shaft 1106 in a direction that approaches each other. The lower wear-resistant plate 9 is in a retracted state. At this time, the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are vertically offset. The retraction power unit 1107 pushes the intermediate shaft 1106 to move downward, so that the first inclined plate 1104 and the second inclined plate 1105 move around the intermediate shaft 1106 in a direction that moves away from each other. At this time, the lower wear-resistant plate 9 is in an unfolded state. At this time, the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are vertically aligned.

[0058] When the front wall thickness detection module 12 measures that the thickness of the lower wear-resistant plate 9 is less than a certain value than the thickness of the upper wear-resistant plate 10, the replacement unit 11 is activated, and the retraction power unit 1107 is activated, causing the lower wear-resistant plate 9 to switch to a retracted state. Then, the winding device 1101 is activated, and the connecting rope on it pulls the lower wear-resistant plate 9 upward. During the process, the other end of the connecting rope is released, and the upper wear-resistant plate 10 moves downward under the action of gravity. Finally, the upper wear-resistant plate 10 falls to the original position of the lower wear-resistant plate 9, while the lower wear-resistant plate 9 moves to the original height of the upper wear-resistant plate 10. Then, the retraction power unit is activated. Unit 1107 converts the lower wear plate 9 to an unfolded state. At this time, the positions of the lower wear plate 9 and the upper wear plate 10 are swapped, and the upper wear plate 10 is in the area with a faster wear rate. In this way, after the positions of the lower wear plate 9 and the upper wear plate 10 are swapped, the overall wear degree of the two is roughly the same. With the help of the moving device 7 that can move the lower wear plate 9 and the upper wear plate 10, the lower wear plate 9 and the upper wear plate 10 can be kept in synchronous wear. In this way, the inner plate 5 can be used for a longer period of time before replacement, which can extend the service life of the inner plate 5.

[0059] It should be noted that in order to keep the lower wear plate 9 and the upper wear plate 10 stable during the up and down movement, a guide block 1001 is provided in the upper wear plate 10, and a guide groove 1111 is provided in the replacement unit 11. The guide block 1001 and the guide groove 1111 cooperate.

[0060] A guide plate 1108 is provided on the inner frame 1102. A slider 1109 is connected to the guide plate 1108. A guide rail 1110 is inserted into the slider 1109. The guide rail 1110 is connected to the outer frame. A guide groove 1111 is provided inside the outer frame.

[0061] Working principle:

[0062] The side detection module 803 can be an electromagnetic ultrasonic detection sensor. The electromagnetic ultrasonic detection sensor is installed in the side detector mounting slot 802. Multiple electromagnetic ultrasonic detection sensors can measure the wall thickness at multiple points of the wear-resistant side plate 801. Based on the measured data, the wear condition of the wear-resistant side plate 801 can be judged. If the wear exceeds the set value, the wear-resistant side plate 801 can be pushed to move closer to the outer wall of the roller 1 through the side detection feeding unit 8, shortening the distance between the wear-resistant side plate 801 and the outer wall of the roller 1. At this time, the worn wear-resistant side plate 801 can still block the material in the working area.

[0063] When the front wall thickness detection module 12 measures that the thickness of the lower wear-resistant plate 9 is less than a certain value than the thickness of the upper wear-resistant plate 10, the replacement unit 11 is activated, and the retraction power unit 1107 is activated, causing the lower wear-resistant plate 9 to switch to a retracted state. Then, the winding device 1101 is activated, and the connecting rope on it pulls the lower wear-resistant plate 9 upward. The other end of the connecting rope is released, and the upper wear-resistant plate 10 moves downward under the action of gravity. Finally, the upper wear-resistant plate 10 falls to the original position of the lower wear-resistant plate 9. Then, the retraction power unit 1107 is activated, causing the lower wear-resistant plate 9 to... When the plate is switched to the unfolded state, the positions of the lower wear plate 9 and the upper wear plate 10 are reversed. At this time, the upper wear plate 10 is in the area with a faster wear rate. Thus, after the positions of the lower wear plate 9 and the upper wear plate 10 are reversed, the overall wear degree of the two is roughly the same. With the help of the moving device 7 that can move the lower wear plate 9 and the upper wear plate 10, the lower wear plate 9 and the upper wear plate 10 can be kept in synchronous wear. In this way, the inner plate 5 can be used for a longer period of time before replacement, which can extend the service life of the inner plate 5.
