The static grinding disc is generally installed on the upper cover through the static grinding disc frame. A tightening spring is provided between the static grinding disc frame and the upper cover. The adjusting screw nut on the gap adjustment hand wheel is engaged with the adjusting screw rod at the upper end of the static grinding disc frame. By rotating the gap adjustment hand wheel, the static grinding disc frame moves up and down relative to the upper cover, thereby adjusting the gap between the static grinding disc and the dynamic grinding disc to control the particle size of the bean dregs when the pulping machine is working.
[0003] However, during the gap adjustment process, the uneven circumferential pressure of the tightening spring causes uneven force on the static grinding disc frame, resulting in the static grinding disc and the dynamic grinding disc being non-parallel. After working for a long time, problems such as uneven slag particle size, low pulping rate, increased wear on the static grinding disc and the dynamic grinding disc are prone to occur, which directly affects the normal operation of the refiner.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0021] Please see attached Figure 1 In the prior art, the static grinding disc gap adjustment device 2 includes a static grinding disc frame 202 connected to the static grinding disc 102, and a gap adjustment hand wheel 201 is provided on the upper cover 1. The static grinding disc 102 of the existing pulping machine is generally installed on the upper cover 1 through the static grinding disc frame 202. A tightening spring 4 is provided between the static grinding disc frame 202 and the upper cover 1. An adjusting screw rod 5 is provided at the upper end of the static grinding disc frame 202. The adjusting nut on the gap adjustment hand wheel 201 is engaged with the adjusting screw rod 5 at the upper end of the static grinding disc frame 202. By rotating the gap adjustment hand wheel 201, the static grinding disc frame 202 moves up and down relative to the upper cover 1, thereby adjusting the gap between the static grinding disc 102 and the dynamic grinding disc 3 to control the particle size of the bean dregs when the pulping machine is working.
[0022] For the static grinding disc gap adjustment device 2 in the above-mentioned prior art, due to the uneven circumferential pressure of the tightening spring 4, the static grinding disc frame 202 is unevenly stressed, resulting in the grinding surface of the static grinding disc 102 being non-parallel to the grinding surface of the dynamic grinding disc 3. After working for a long time, problems such as uneven slag particle size, low pulping rate, and increased wear of the static grinding disc 102 and the dynamic grinding disc 3 are prone to occur, which directly affect the normal operation of the refiner. In addition, since the tightening spring 4 is compressed and the pressure is relatively high, it is difficult to assemble the refiner, and it is laborious to rotate and adjust the gap adjustment handwheel 201. At the same time, since the waterproofing of the refiner is generally achieved simply by using an oil seal 6, after running for a period of time, the oil seal 6 is damaged. When cleaning, it is easy to cause water to enter the bearing, damaging the bearing or even the motor. In order to solve the above problems, the present application proposes the following two embodiments.
[0023] Embodiment 1
[0024] See attached Figure 2 and attached Figure 3As shown, a gap adjustment device for a grinding assembly of a pulping machine comprises an upper cover 1 and a grinding barrel. A grinding assembly consisting of a moving grinding disc 3 and a static grinding disc 102 is arranged in the grinding barrel. The static grinding disc 102 is connected to the upper cover 1. A bearing seat 12 is arranged in the grinding barrel. The moving grinding disc 3 is mounted on the grinding barrel through the bearing seat 12 and the bearing. A static grinding disc gap adjustment device 2 is arranged on the upper cover 1. The static grinding disc gap adjustment device 2 includes a static grinding disc frame 202 connected to the static grinding disc 102, and at least three synchronous wheels 204 are provided on the upper cover 1 (three in this embodiment, evenly distributed along the circumference of the upper cover 1), and each synchronous wheel 204 is sleeved with a gap adjustment shaft 206, and at least one gap adjustment shaft 206 (one in this embodiment) is coaxially mounted with a gap adjustment worm wheel 203, and the external teeth on the gap adjustment worm wheel 203 are meshed with the external teeth on the gap adjustment handwheel 201 arranged on the upper cover 1, each gap adjustment shaft 206 is provided with an external thread and is threadedly connected to the static grinding disc frame 202, and each synchronous wheel 204 is surrounded by a synchronous belt 205 so that each synchronous wheel 204 is connected in series by the synchronous belt 205.
[0025] The utility model also includes a frame, on which an upper cover 1 and a power source (a motor in this embodiment) are installed. When the utility model is working, the motor is started, and the motor shaft drives the moving grinding disc 3 to rotate through the grinding shaft to make the grinding assembly work. The raw material (soaked soybeans in this embodiment) is poured into the grinding barrel through the feed hopper 101, and the liquid supply pump supplies liquid to the grinder from the liquid supply device of the grinder (pure water in this embodiment). Under the action of centrifugal force, the ground soybean milk and bean dregs are sent to the liquid collection device through the filter screen on the filter screen frame and the liquid outlet. The soybean milk in the liquid collection device is a high-concentration, high-quality raw soybean milk product, and the bean dregs are thrown out from the dregs outlet and collected for further processing.
[0026] When the gap between the moving grinding disc 3 and the static grinding disc 102 in the grinding assembly needs to be adjusted, as shown in FIG. Figure 3 As shown, the gap adjustment hand wheel 201 is rotated clockwise or counterclockwise, and the gap adjustment worm wheel 203 thereof rotates accordingly, and the synchronous wheel 204 and the gap adjustment shaft 206 on the gap adjustment worm wheel 203 also rotate accordingly, thereby driving other synchronous wheels 204 and gap adjustment shafts 206 to rotate through the synchronous belt 205, so that the static grinding disc frame 202 threadedly connected with each gap adjustment shaft 206 will move up and down, thereby driving the static grinding disc 102 installed on the static grinding disc frame 202 to move up and down, so as to achieve the function of changing the gap between the static grinding disc 102 and the dynamic grinding disc 3. Since the static grinding disc gap adjustment device 2 adopts a set of worm gear structures with a large speed ratio, the gap adjustment hand wheel 201 is relatively labor-saving when operating, and the gap adjustment precision is better controlled through the cooperation of the large speed ratio, the overall structure is compact and reasonable, and the durability of the gap adjustment mechanism is better guaranteed. At the same time, since the synchronous wheels 204 are evenly distributed along the circumference of the upper cover 1, the force distribution of the static grinding disc frame 202 is even, avoiding the problem of the static grinding disc 102 being tilted when moving up and down and causing it to be non-parallel with the dynamic grinding disc 3, thereby achieving the effect of stably adjusting the gap between the static grinding disc 102 and the dynamic grinding disc 3.
