During the filling process, it is impossible to filter impurities in the polyurethane material, which can easily lead to clogging of the filling head, making it very inconvenient to use. Therefore, we have proposed an automatic filling device for polyurethane materials for coal mine reinforcement to solve the above problems. Utility Model Content

[0018] like Figure 1 As shown, in some embodiments, the left and right sides of the frame 1 are open structures, and an observation window 11 is hinged to the front side wall of the frame 1 near the left and right positions.

[0019] In this embodiment, the frame 1 facilitates the movement of the filling barrel on the conveyor belt assembly 2, and the observation window 11 facilitates the viewing of the filling process.

[0020] like Figure 3 As shown, in some embodiments, the guiding mechanism 3 includes a second electric telescopic rod 301 and a guide plate 302. The second electric telescopic rod 301 is respectively installed on the front and rear inner walls of the frame 1, and the guide plate 302 is fixedly installed on the side of the front and rear second electric telescopic rods 301 facing each other.

[0021] In this embodiment, the output shaft of the front and rear second electric telescopic rods 301 drives the front and rear guide plates 302 to move back and forth, adjusting the distance between the front and rear guide plates 302 so that the front and rear guide plates 302 guide the front and rear sides of the filling barrel.

[0022] like Figure 2 As shown, in some embodiments, the positioning mechanism 4 includes a slide rod 401, a rectangular sleeve 402, a locking bolt 403, and a sensing probe 404. The slide rod 401 is fixedly installed on the side of the guide plate 302. The rectangular sleeve 402 is movably sleeved on the slide rod 401, and the rectangular sleeve 402 is locked and fixed to the slide rod 401 by the locking bolt 403. The sensing probe 404 is installed on the upper surface of the front and rear rectangular sleeves 402.

[0023] In this embodiment, the locking bolt 403 is tightened or loosened, causing the rectangular sleeve 402 to move left and right on the slide rod 401. The rectangular sleeve 402 drives the sensing probe 404 to move left and right. The sensing probe 404 senses the position of the filling barrel and feeds the information back to the control mechanism 9. The control mechanism 9 controls the opening and closing of the conveyor belt assembly 2, so that the filling barrel on the upper surface of the conveyor belt assembly 2 moves accurately to directly below the filling head 8.

[0024] like Figure 4 As shown, in some embodiments, the filtering mechanism 6 includes a rectangular box 601, a filter screen sleeve 602, and a plug 603. The rectangular box 601 is installed on the lower surface of the output shaft of the first electric telescopic rod 5. The filter screen sleeve 602 is installed between the upper and lower side walls of the rectangular box 601. The filter screen sleeve 602 covers the upper surface of the filling head 8. Plugs 603 are threaded onto both the left and right ends of the rectangular box 601.

[0025] In this embodiment, the rectangular box 601 is used to move the polyurethane material, so that the polyurethane material flows into the filling head 8 through the filter screen 602, thereby achieving the effect of filtering impurities in the polyurethane material. The plug 603 is opened to facilitate cleaning and impurity removal inside the rectangular box 601.

[0026] like Figure 3As shown, in some embodiments, the extraction mechanism 7 includes an extraction pump 701, a hose 702, and a connecting pipe 703. The extraction pump 701 is installed on the rear side wall of the frame 1. The outlet of the extraction pump 701 is connected to the rectangular box 601 through the hose 702. The connecting pipe 703 is installed on the inlet of the extraction pump 701.

[0027] In this embodiment, the extraction pump 701 extracts the polyurethane material in the storage cylinder through the connecting pipe 703, so that the polyurethane material flows into the rectangular box 601 through the hose 702.

[0028] like Figure 3 As shown, in some embodiments, the control mechanism 9 includes an electronic flow meter 901, a solenoid valve 902, and a controller 903. The electronic flow meter 901 and the solenoid valve 902 are installed sequentially from bottom to top on the filling head 8, and the controller 903 is installed on the front side of the frame 1.

[0029] In this embodiment, the electronic flow meter 901 monitors the flow rate of the filling head 8 and feeds the information back to the controller 903. After the set flow rate is reached, the controller 903 closes the solenoid valve 902.

[0030] like Figure 3 As shown, in some embodiments, the collection mechanism 10 includes a third electric telescopic rod 101, a placement tray 102, and a collection tray 103. The third electric telescopic rod 101 is evenly installed on the rear inner wall of the frame 1. The placement tray 102 is fixedly installed between the front sides of the output shaft of the third electric telescopic rod 101. The collection tray 103 is placed on the upper surface of the placement tray 102.

[0031] In this embodiment, the output shaft of the third electric telescopic rod 101 drives the collection plate 103 on the upper surface of the placement plate 102 to move below the filling head 8 pair, so as to collect the liquid dripping from the filling head 8.

[0032] In use, the filling barrel to be filled is placed on the upper surface of the conveyor belt assembly 2. According to the specifications of the filling barrel, the output shaft of the front and rear electric telescopic rods 301 in the guiding mechanism 3 drives the front and rear guide plates 302 to move back and forth. The distance between the front and rear guide plates 302 is adjusted so that the front and rear guide plates 302 guide the front and rear sides of the filling barrel. Then, by tightening and loosening the locking bolts 403 in the positioning mechanism 4, the rectangular sleeve 402 moves left and right on the slide rod 401, so that the rectangular sleeve 402 drives the sensing probe 404 to move left and right. The sensing probe 404 senses the position of the filling barrel. The information is fed back to the controller 903 in the control mechanism 9. When the filling barrel detected by the sensor 404 moves to the set position, the controller 903 stops the conveyor belt assembly 2 and the filling barrel is positioned directly below the filling head 8. At this time, the output shaft of the third electric telescopic rod 101 in the collection mechanism 10 drives the collection tray 103 on the upper surface of the placement tray 102 to move backward. The collection tray 103 moves away from below the filling head 8. The output shaft of the first electric telescopic rod 5 drives the filling head 8 on the lower surface of the filter mechanism 6 to insert into the filling barrel. Then, the extraction pump 701 in the extraction mechanism 7 passes through the connecting pipe 703 to... Polyurethane material is extracted from the storage tank and flows through hose 702 into rectangular box 601 in filter mechanism 6. Impurities in the polyurethane material are filtered through filter screen 602. The filtered polyurethane material then flows through filter screen 602 into filling head 8, which injects it into filling container. During the filling process, electronic flow meter 901 monitors the flow rate of filling head 8 and feeds the information back to controller 903. When the set flow rate is reached, controller 903 closes the corresponding solenoid valve 902 of filling head 8. When all electronic flow meters 901 reach the set flow rate... When the set value is reached, the information is fed back to the controller 903. The controller 903 shuts down the extraction pump 701, and the output shaft of the first electric telescopic rod 5 drives the filling head 8 to reset upward. The output shaft of the third electric telescopic rod 101 in the collection mechanism 10 drives the collection plate 103 on the upper surface of the placement plate 102 to move below the filling head 8, so as to collect the dripping liquid from the filling head 8. This cycle is repeated to fill polyurethane material, thereby realizing automatic filling, higher filling dosage accuracy, and filtering of impurities during the filling process, effectively avoiding clogging of the filling head 8, greatly improving filling efficiency and facilitating use.

[0033] In summary, this automatic filling device for polyurethane materials used in coal mine reinforcement achieves automatic filling with higher dosage accuracy. During the filling process, it can filter impurities, effectively preventing clogging of the filling head 8, greatly improving filling efficiency. The filling barrel moves more stably and accurately, avoiding dripping from the filling head 8, which is beneficial for use.
