DETAILED DESCRIPTION
[0021] The utility model will be further described in combination with the drawings. These drawings are all simplified schematic views, and only illustrate the basic structure of the utility model in a schematic manner, so that only the structures related to the utility model are shown, and the directions and references (such as up, down, left, right, etc.) can only be used to help the description of the features in the drawings. Therefore, the following detailed description is not in a limiting sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalents.
[0022] As shown in Figures 1-3 A floating material blocking mechanism of a coffee bean grinder, the grinder comprises at least two press rollers 1 which can move towards or away from each other and vertical plates 2 for mounting the press rollers 1, the number of the vertical plates 2 is two and they are distributed on both sides of the press rollers 1 in the axial direction for inserting the end portions of the press rollers 1, the grinder further comprises a floating material blocking mechanism and a fixed material blocking mechanism which enclose a grinding chamber for grinding coffee beans, the fixed material blocking mechanism comprises a lower roller plate 13 below the press rollers 1 and a side roller plate 14 outside the press rollers 1, the lower roller plate 13 and the side roller plate 14 are fixed with the vertical plates 2, coffee beans are generally poured from above and from the middle of the two press rollers 1, coffee beans reaching the position of the side roller plate 14 are less, and coffee beans reaching the position of the lower roller plate 13 are generally all ground, so there is no need to consider the problem of direct leakage without grinding.
[0023] The floating material blocking mechanism is floatingly arranged above the press rollers 1, in the embodiment, the number of the press rollers 1 is two and they are arranged transversely side by side, when the two press rollers 1 move towards or away from each other under the action of a cam, the press rollers 1 will move longitudinally during transverse movement due to the characteristics of the cam itself, and the floating material blocking mechanism can move synchronously with the press rollers 1 during the movement of the press rollers 1.
[0024] The floating material blocking mechanism comprises upper roller plates 3 inside the vertical plates 2, the number of the upper roller plates 3 is two and they correspond to the two vertical plates 2 one by one, the upper roller plates 3 protrude towards the vertical plates 2 and form slide columns 4, the slide columns 4 are located at the central portions of the upper roller plates 3, the vertical plates 2 form longitudinal slide grooves 6 inside for the slide columns 4 to slide, and elastic members 5 are arranged between the slide columns 4 and the groove walls of the slide grooves 6, the elastic members 5 can be springs.
[0025] Coffee beans are added from above the press rollers 1 and then ground between the two press rollers 1 during grinding, and the coffee beans will be scattered around under the extrusion of the press rollers 1, if the distance between the upper roller plates 3 and the press rollers 1 is too large, part of the coffee beans will not be ground or not be completely ground and directly discharged, the upper roller plates 3 in the embodiment have a certain floating space by using the slide grooves 6 and the elastic members 5, when the press rollers 1 move transversely and longitudinally, the upper roller plates 3 can displace under the pushing action of the press rollers 1, so as to avoid that the fixed upper roller plates 3 either interfere with the movement of the press rollers 1 or have too large a gap with the press rollers 1, causing a large amount of coffee beans which are not ground or not completely ground to leak out and waste.
[0026] In some examples, the vertical plate 2 is provided with a slot slider 7 rotatingly arranged inside, and the sliding slot 6 is arranged inside the slot slider 7. When the two compression rollers 1 are respectively connected with a cam to realize the distance adjustment, the two cams are not necessarily arranged symmetrically, and thus the movement strokes of the two compression rollers 1 are not completely the same. It is possible that one of the compression rollers 1 is synchronously moved upward in the horizontal movement process, and the other compression roller 1 is synchronously moved downward in the horizontal movement process. At this time, the upper roller plate 3 needs to be inclined to avoid interference with the compression roller 1. In the embodiment, the rotatingly arranged slot slider 7 can allow the upper roller plate 3 to slightly rotate while floating up and down to realize the inclined state.
[0027] In some examples, the vertical plate 2 is provided with a through slot 8 for installing the slot slider 7. The through slot 8 penetrates through the end faces of the two ends of the vertical plate 2, and the upper roller plate 3 is arranged on one side of the axial direction of the through slot 8 for plugging the side to limit the slot slider 7 from being taken out from the side of the through slot 8. The other side of the through slot 8 is provided with a limiting piece for limiting the slot slider 7 from being taken out. The limiting piece can be a cover of the grinder, or can be a mounting bracket. The mounting bracket can be used to install a driving mechanism for driving the cam to rotate.
[0028] In some examples, a sliding block 9 is slidingly installed in the sliding slot 6. The sliding block 9 is fixed with the sliding column 4, and an accommodation slot 10 for accommodating one end of the elastic piece 5 is arranged at the end of the sliding block 9 away from the sliding column 4. The other end of the elastic piece 5 abuts against the upper slot wall of the sliding slot 6, and the wall surface of the upper slot wall is a plane. The upper slot wall with the plane structure can improve the connection strength with the elastic piece 5. The sliding block 9 is substantially a T-shaped structure, and the end surface of the sliding block 9 close to the sliding column 4 is an arc surface matched with the outer peripheral wall of the sliding column 4.
[0029] In some examples, as shown in Figure 4 and Figure 5 At least two fixing plates 11 are arranged between the two vertical plates 2. The fixing plates 11 and the vertical plates 2 are crossed with each other to fix the two vertical plates 2. The at least two fixing plates 11 are distributed on the two sides of the upper roller plate 3 to limit the upper roller plate 3. There is a gap between the fixing plate 11 and the upper roller plate 3 in the horizontal state to allow the upper roller plate 3 to slightly rotate. The lower roller plate 13 is attached to the fixing plate 11 at the two ends.
[0030] In some examples, as shown in Figure 6 The upper roller plate 3 has an arc-shaped matching surface 12 matched with the shape of the outer peripheral wall of the compression roller 1. In the embodiment, the number of the compression rollers 1 is two, and thus each upper roller plate 3 has two arc-shaped matching surfaces 12. Each lower roller plate 13 also has two arc-shaped matching surfaces 12.
[0031] Working principle:
[0032] When the cam drives the compression roller 1 to move to adjust the spacing, the compression roller 1 moves longitudinally while moving transversely, the arc-shaped matching surface 12 of the upper roller plate 3 is pushed by the compression roller 1, the slide column 4 of the upper roller plate 3 slides in the slide groove 6 and is matched with the elastic member 5 to drive the upper roller plate 3 to move synchronously, so that the fixed upper roller plate 3 is not interfered with the movement of the compression roller 1 due to being attached to the compression roller 1, or a large amount of coffee beans that are not ground or not completely ground leaks out due to the large gap between the compression roller 1 and the upper roller plate 3.
[0033] With the above ideal embodiments of the present application as the inspiration, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
