DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 6 The present invention provides a technical solution: a food processing crushing device, comprising a food crushing bin 1 with a feed hopper 2, a leak plate 101 installed inside the food crushing bin 1, a collecting box 3 slidably connected inside the food crushing bin 1, a discharge pipe 4 connected to the side wall of the food crushing bin 1, a first rotating shaft 5 and a second rotating shaft 7 rotatably connected inside the feed hopper 2, a first crushing roller 6 is fixedly sleeved on the outside of the first rotating shaft 5, a second crushing roller 8 is fixedly sleeved on the outside of the second rotating shaft 7, and a filter plate 9 is movably installed inside the food crushing bin 1;

[0032] It should be noted that a leakage plate 101 is installed inside the food crushing bin 1, and a collecting box 3 is placed under the leakage plate 101 to slide. During processing, the filtered raw materials can leak into the collecting box 3 through the leakage plate 101, and the collecting box 3 can be slid out to facilitate the staff to take the raw materials after crushing.

[0033] Also includes:

[0034] A moving member, used for driving the first crushing roller 6 to move horizontally;

[0035] A driving member, used for driving the first rotating shaft 5 and the second rotating shaft 7 to rotate;

[0036] The vibrating member is used to drive the filter plate 9 to vibrate.

[0037] In this embodiment, Figure 5 As shown, the moving parts include:

[0038] The screw 63 is rotatably connected to the inside of the feed hopper 2, a support shaft 61 is fixed to the side wall of the feed hopper 2, the outside of the support shaft 61 is rotatably sleeved with the support shaft 61, the outside of the support shaft 61 is rotatably sleeved with a knob 62, the inside of the knob 62 is provided with an external thread that matches the thread of the screw 63, the bottom of the screw 63 is rotatably connected to a slider 64, and the second rotating shaft 7 is placed in the slider 64 for rotational movement.

[0039] In this embodiment, Figure 1 As shown, the side wall of the feed hopper 2 is provided with a slide groove 201 for facilitating the sliding of the slider 64 , and a limit plate 65 is fixed to the inner wall of the slide groove 201 , and the slider 64 is slidably sleeved with the limit plate 65 .

[0040] It should be noted that the knob 62 is internally installed with an external thread that cooperates with the thread of the screw rod 63. Therefore, when it rotates, the screw rod 63 inside it cooperates with it and moves horizontally, so that the slider 64 placed in the slide groove 201 slides and then drives the second crushing roller 8 installed through the second rotating shaft 7 to move, so that the distance between the second crushing roller 6 and the first crushing roller 6 is adjusted.

[0041] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the drive member includes:

[0042] The motor 72 and the side wall of the food crushing bin 1 are fixed with a fixing plate 71 , the motor 72 is fixed above the fixing plate 71 , the output end of the motor 72 is fixedly connected to the first rotating shaft 5 , and the first rotating shaft 5 and the second rotating shaft 7 are connected through a transmission assembly.

[0043] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transmission assembly includes:

[0044] The first gear 73 is fixedly sleeved on the coaxial outside of the first rotating shaft 5, the upper end of the first gear 73 is meshed with the second gear 74, the end side of the second gear 74 is meshed with the third gear 75, the bottom of the third gear 75 is meshed with the fourth gear 77, and the fourth gear 77 is fixedly connected to the second rotating shaft 7.

[0045] It should be noted that the third gear 75 is meshed with the fourth gear 77. Since the spacing gap of the second crushing roller 8 is not large, the fourth gear 77 is always meshed with the third gear 75 during the movement, so transmission can be achieved.

[0046] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, two pillars 76 are fixed to the side wall of the feed hopper 2, and the second gear 74 and the third gear 75 are rotatably sleeved with the two pillars 76 respectively.

[0047] In this embodiment, Figure 1 , Figure 2 ,and Figure 6 As shown, a mounting plate 91 is fixed to the side wall of the food crushing bin 1 , a spring 92 is fixed to the top of the mounting plate 91 , and the spring 92 is fixedly connected to the filter plate 9 .

[0048] It should be noted that two springs 92 are installed at the bottom of the filter plate 9 so that the filter plate 9 will not be unstable during vibration and can be reset by the elastic properties of the springs 92 .

[0049] In this embodiment, Figure 6 As shown, the vibration element includes:

[0050] A transmission rod 96 is rotatably connected to the side wall of the food crushing bin 1, a second pulley 95 is fixedly sleeved on the outside of the transmission rod 96, a first pulley 93 is fixedly sleeved on the outside of the first rotating shaft 5, a belt 94 is wound around the outside of the first pulley 93 and the second pulley 95, a cam 97 is fixedly sleeved on the outside of the transmission rod 96, and the cam 97 is in the same vertical plane as the filter plate 9.

[0051] It should be noted that the specific model and specifications of the motor 72 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0052] The use method and advantages of the present invention: When the food processing crushing device is working, the working process is as follows:

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when the crushing device is used to crush food, the spacing between the first crushing roller 6 and the second crushing roller 8 is first adjusted according to the particle size of the food to be crushed, and the knob 62 is manually rotated to rotate around the support shaft 61. When the knob 62 rotates, it is threadedly engaged with the screw 63 inside it. The screw 63 is driven by the force to drive the slider 64 to move horizontally along the limit plate 65 in the slide groove 201, and then the position of the second crushing roller 8 is adjusted, so that the spacing between the crushing rollers can be adjusted according to the particle size of the food to be crushed, thereby improving the flexibility of use. At the same time, during the movement, the fourth gear 77 on the end side of the slider 64 rotates and meshes with the third gear 75 to avoid separation between the two and affect the subsequent stable use;

[0054] After the adjustment is completed, the motor 72 is started to drive the first rotating shaft 5 to rotate, and the first gear 73 outside the first rotating shaft 5 rotates and meshes with the second gear 74, and the third gear 75 also meshes with it, and the second gear 74 and the third gear 75 rotate around the support shaft 61, and at the same time, the fourth gear 77 is also synchronously meshed to drive the second rotating shaft 7 placed in the slider 64 to rotate, so that the first crushing roller 6 outside the first rotating shaft 5 and the second crushing roller 8 outside the second rotating shaft 7 rotate synchronously to grind the food raw materials, and the crushed food raw materials leak into the filter plate 9;

[0055] At this time, the first pulley 93 outside the first rotating shaft 5 also rotates synchronously, and drives the second pulley 95 to rotate through the transmission of the belt 94, and the transmission rod 96 in the middle drives the cam 97 to rotate. When the cam 97 rotates to its bottom and contacts the filter plate 9, it will collide with it. The filter plate 9 is pressed down by the spring 92. When the cam 97 rotates continuously, it will intermittently reciprocate to hit the filter plate 9. Combined with the elastic performance of the spring 92, the filter plate 9 vibrates and then the evenly crushed raw materials pass through the mesh of the filter plate 9 into the collection box 3 below. The large particles of raw materials that are not evenly crushed are vibrated and sent out through the discharge pipe by the vibration of the filter plate 9. The staff collects them by placing an external collection container, so that the large particles of raw materials that are not evenly crushed can be automatically selected and collected during the crushing process, so that they can be crushed again for the second time, which not only improves the work efficiency but also reduces the labor intensity of the workers.

[0056] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.
