Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pellet detection, in particular to an online anti-pressing detection equipment for finished pellets. BACKGROUND

[0002] Pelletizing is a very important link in the production process of pellet, and the finished pellets produced are also called finished pellets. The finished pellets should have a certain anti-pressing capacity to prevent them from being broken during storage, transportation and other processes. Therefore, the anti-pressing strength is a key indicator for evaluating the quality of finished pellets.

[0003] At present, the detection means of the anti-pressing strength indicator of the finished pellets is usually that the staff takes a certain number of finished pellets just produced in the production site, then manually screens them using a screen, leaves the finished pellets meeting the test size as test balls, takes them to the detection room for determination by a pressure testing machine, slowly pressurizes the test balls, records the pressure value when they are broken, thereby obtaining the anti-pressing strength of a single test ball, and takes the average value of the pressure values when all the test balls are broken as the final anti-pressing strength indicator. However, from taking the test balls from the production site to determining the anti-pressing strength in the detection room, the overall time consumption is relatively long, and since the finished pellets just produced contain a certain amount of moisture, the screen holes are easily caked with material powder after each screening, causing the screen holes to be blocked, which needs to be cleaned in time, resulting in a large labor intensity of the staff and further reducing the detection efficiency.

[0004] The published patent CN 116165069 A discloses an online anti-pressing detection system and method for finished pellets, which still has the following defects in actual application: 1) the material taking assembly adopts an electromagnetic suction material taking mode, which is not suitable for the finished pellets made of materials with weak iron oxide magnetism or in the presence of iron impurities, easily leading to low suction efficiency of the material taking assembly and problems of interference in the working process; 2) the material separating assembly separates the pellets by lifting them from the material pile with a separating column, but since the finished pellets have a certain rolling property and the end area of the separating column is relatively small, the empty material is extremely easy to appear; 3) the detection unit does not consider that the finished pellets for detection may be interfered with the authenticity of the anti-pressing detection data due to surface cracks; 4) there is a lack of material discharge design, so that the remaining finished pellets picked up each time need to be manually removed, otherwise they will enter the detection unit in turn, resulting in low detection efficiency.

[0005] Therefore, it is necessary to further improve the online anti-pressing detection system for finished pellets to improve the working efficiency of the anti-pressing detection of the finished pellets. SUMMARY

[0044] The feeding slider 2-2 comprises an electric push rod and a slider; the slider is arranged at the starting end of the feeding channel 2-3 and located at the rear side of the ball outlet of the distributor 2-1; the electric push rod is horizontally fixed on the detection platform 8, and the movable rod end thereof is fixed on the rear end face of the slider, so as to drive the slider to push the finished ball to move along the feeding channel 2-3 by means of the electric push rod, so that the finished ball entering the feeding channel 2-3 reaches the lower pressing head at the terminal end along the feeding channel 2-3. As a preferred technical solution of the embodiment, in order to ensure that the finished ball can move to the central position of the lower pressing head, the front end of the slider has a V-shaped claw, so that the finished ball is pushed to the lower pressing head in a manner of being embedded in the V-shaped claw.

[0046] In the initial state, the moving block 2-1-2 is located in the middle of the box body 2-1-1, and the large-diameter front end of the T-shaped pin 2-1-3 is abutted against the top surface of the box body 2-1-1 and is arranged obliquely; when the electric push rod pushes the slider to move to the terminal end of the feeding channel 2-3, the rear push plate 2-5 is abutted against the front end of the T-shaped pin 2-1-3, and the T-shaped pin 2-1-3 is pushed to drive the moving block 2-1-2 to move forward synchronously until the front end of the box body 2-1-1 is reached, at this time, the finished balls fall from the dispenser 2-1 to the feeding channel 2-3, and the front end of the T-shaped pin 2-1-3 falls into the wedge-shaped groove and is separated from the rear push plate 2-5, the slider continues to push the finished balls to move forward, and the moving block 2-1-2 returns to the initial position under the spring return action between the moving block and the box body, that is, the T-shaped pin 2-1-3 leaves the wedge-shaped groove and returns to the state of abutting against the top surface of the box body 2-1-1; when the slider completes the feeding, the electric push rod can be retracted to the initial position, and the above process is repeated until the feeding action that meets the detection times is completed; since there are still residual finished balls in the collector 1-5 after the pressure detection is completed, the electric push rod continues to retract, the slider moves backward from the initial position, the front push plate 2-4 is abutted against the front end of the T-shaped pin 2-1-3, and the T-shaped pin 2-1-3 is pushed to drive the moving block 2-1-2 to move backward synchronously until the rear end of the box body 2-1-1 is reached, at this time, the ball inlet hole of the box body 2-1-1 is communicated with the ball discharge hole, and the residual finished balls in the collector 1-5 can be discharged through the ball inlet hole, the ball discharge hole and the third discharge port in sequence; then the slider moves to the initial position under the action of the electric push rod, and the moving block 2-1-2 also returns to the initial position under the spring return action between the moving block and the box body.

[0047] The feeding device 2 cooperates with the feeding device 1 to feed the finished balls to the detection system after the finished balls are screened according to the particle size, which not only considers the problem that the feeding device needs to adapt to the concentrated particle size range of the finished balls in the structural design to ensure that the feeding process does not appear the ball jamming phenomenon and improve the detection efficiency and speed of the finished balls; compared with the existing technology of using a separating column to separate the finished balls from the ball pile, the separator of the feeding device uses the rolling property of the finished balls to realize feeding, and there is no empty material problem.

[0048] Referring to Figure 6 The detection system 3 is arranged above the feeding channel 2-3 and includes a support frame arranged across the width direction of the feeding channel 2-3, and a detection camera 3-1 and a light source 3-2 fixed to the top of the support frame; the detection camera 3-1 is arranged in a manner that the lens faces downward, and the image acquisition range covers the entire feeding channel 2-3 to acquire images of the finished balls entering the feeding channel 2-3; the light source 3-2 is arranged in the same direction as the lens to provide supplementary light during image acquisition.

[0049] The pressure detection tester 4 is a commercially available product, which is matched with the surface detection system 3 to further improve the detection efficiency of the finished ball; wherein the finished ball is in a static state during the pressure application process of the compression detection instrument, and the surface crack of the finished ball will reduce the compression strength of the finished ball, wherein if the crack direction is the same as the pressure application direction, the compression detection data result will be significantly lower than the average value, which can be filtered and removed through the compression data result, but if the crack is short or the crack direction is perpendicular to the pressure application direction, the compression detection data result may be within the normal fluctuation range, which interferes with the detection result, therefore, in the application process of the device, first, the surface detection system 3 is used to detect whether the finished ball has surface cracks in the conveying process of the finished ball in a visual detection manner, so as to determine whether to drive the pressure detection tester 4 to perform compression detection, effectively avoiding the influence of the compression data of the cracked finished ball on the batch detection result, realizing the filtering and removal of the finished ball data of the aforementioned interference detection result, and further improving the compression detection accuracy of the finished ball.

[0050] Referring to Figure 7 and Figure 8 , the cleaning device 5 is arranged on the feeding channel 2-3, which includes a scraper 5-1 arranged on a sliding rail, a turnover mechanism, a positioning mechanism and a reset mechanism.

[0052] The scraper 5-1 is arranged below the sliding plate 5-6, and the two sides are fixed with rotating shafts which can be assembled in the upper strip-shaped through hole, and the shaft ends of the two rotating shafts are rotatably connected on the two sides of the sliding plate 5-6 and extend to the outside of the sliding plate 5-6; in the initial state, the scraper 5-1 is arranged in a way that the board surface on the side facing the pressure detection tester 4 is inclined upward, and the bottom side edge abuts on the groove bottom of the feeding channel 2-3, in a scraping state.

[0053] The turnover mechanism comprises two limiting pins 5-1-1, two front blocking pins 5-2 and two rear blocking pins 5-3. The two limiting pins 5-1-1 are symmetrically and vertically fixed on the plate surface on the side of the scraper 5-1 facing the pressure testing instrument 4. The two front blocking pins 5-2 are symmetrically and vertically fixed on the inner side of the two track plates 5-5 near the end of the feeding channel 2-3, so that when the scraper 5-1 moves to the position where the two limiting pins 5-1-1 and the two front blocking pins 5-2 abut against each other, the scraper 5-1 is turned upward due to the blocking of the front blocking pins 5-2, thereby leaving the feeding channel. The two rear blocking pins 5-3 are symmetrically and vertically fixed on the inner side of the two track plates 5-5 near the starting end of the feeding channel 2-3, so that when the scraper 5-1 moves to the position where the two limiting pins 5-1-1 and the two rear blocking pins 5-3 abut against each other, the scraper 5-1 is turned upward due to the blocking of the rear blocking pins 5-3, thereby returning to the initial scraping state.

[0054] The positioning mechanism comprises two first tension springs 5-7, two rotating blocks 5-8, two positioning pins 5-9 and two fixed pins 5-10. The two rotating blocks 5-8 are symmetrically sleeved and fixed on the shaft ends of the two rotating shafts, so that the rotating blocks 5-8 can rotate synchronously with the rotating shafts. A limiting column is arranged on the rotating block, which is initially vertically arranged on the top surface of the rotating block. The two positioning pins 5-9 are symmetrically and vertically fixed on the outer walls on both sides of the sliding plate 5-6 and located at the rear side of the rotating block 5-8, so that when the rotating block 5-8 rotates clockwise by 60° with the rotating shaft, the limiting column thereon can abut against the positioning pin 5-9. The two fixed pins 5-10 are symmetrically and vertically fixed on the outer walls on both sides near the rear end of the sliding plate 5-6. The two first tension springs 5-7 are respectively arranged on the two sides of the sliding plate 5-6, one end of each first tension spring 5-7 is fixed on the shaft end of the rotating shaft on the same side, and the other end is fixed on the fixed pin 5-10 on the same side. In the initial state, the scraper 5-1 is kept in the scraping state under the action of the two first tension springs 5-7, moves forward synchronously with the sliding plate 5-6, until the bottom side edge of the scraper 5-1 sweeps the pressure plate along the feeding channel 2-3 and reaches the end of the feeding channel 2-3. Then, the scraper 5-1 is turned upward by 60° under the action of the turnover mechanism, at this time, the two rotating blocks 5-8 synchronously rotate clockwise by 60°, so that the limiting column thereon is lapped on the positioning pin 5-9 to limit further turning, and at the same time, the two first tension springs 5-7 are twisted to keep the upward turning state, until the scraper 5-1 retreats to the position where the two rear blocking pins 5-3 are located. Under the opposite action of the rear blocking pin 5-3 and the limiting pin 5-1-1, the scraper 5-1 is turned upward counterclockwise by 60°, returning to the initial scraping state, at this time, the two rotating blocks 5-8 synchronously rotate counterclockwise with the scraper 5-1, returning to the initial state, and under the action of the two first tension springs 5-7, the scraper 5-1 is kept in the current turning state.

[0055] The reset mechanism is composed of two second fixing pins 5-11 and two second tension springs 5-4. The two second fixing pins 5-11 are symmetrically and vertically fixed on the two side outer walls near the front end of the sliding plate 5-6. The two second tension springs 5-4 are respectively arranged on the two sides of the sliding plate 5-6, and one end of each second tension spring 5-4 is fixed on the second fixing pin 5-11 on the same side, and the other end is fixed at the starting end of the feeding channel 2-3. In the initial state, the slider moves forward and abuts against the rear end of the sliding plate 5-6, so that the sliding plate 5-6 moves forward synchronously under the pushing of the slider. When the slider moves back to the initial position, the sliding plate 5-6 is pulled back to the initial position from the end of the feeding channel 2-3 under the action of the reset mechanism.

[0056] The cleaning device 5 is designed to be in action linkage with the feeding slider 2-2, so that the scraper 5-1 moves forward with the slider in front of the finished balls to sweep the waste and foreign matters on the feeding channel 2-3 and the pressing plate along the way. When reaching the end of the feeding channel, the scraper 5-1 is turned upward to leave the feeding channel 2-3, so that the finished balls on the rear side are smoothly pushed by the slider to the pressing plate for pressure detection. Then, when the slider retreats to the initial position, the scraper 5-1 also retreats to the initial position with the sliding plate 5-6, returning to the initial state.

[0057] The discharging device 6 includes a first discharging pipe, a second discharging pipe and a third discharging pipe, which are respectively arranged at the first discharging port, the second discharging port and the third discharging port of the detection platform 8, and the top end of the discharging pipe is connected with the discharging port, and the bottom end extends above the conveying belt and is arranged in a way that the port faces downward.
