DETAILED DESCRIPTION

[0044] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0045] like Figure 1-Figure 3 As shown, in the first aspect, an embodiment of the present application provides a cross-screen roller spacing adjustment mechanism, which includes a bearing seat 1, a connecting plate 2, a first tightening assembly 3 and a second tightening assembly 4.

[0046] The bearing seat 1 is used to be fixedly connected to the ground or other fixed devices to carry the screen roller 7.

[0047] The connecting plate 2 may be constructed as a rectangular plate-shaped structure, and the connecting plate 2 is used for slidably connecting the bearing seat 5 of the screen roller 7 , wherein the bearing seat 5 can slide along the length direction of the connecting plate 2 .

[0048] The first clamping component 3 is connected to the connecting plate 2, and the first clamping component 3 has a movable first clamping end for contacting one side of the bearing seat 5, that is, the first clamping end can contact one side of the bearing seat 5 in an active state. For example, when the position of the bearing seat 5 on the connecting plate 2 changes, the first clamping end can contact one side of the bearing seat 5 after being movable.

[0049] The second tightening component 4 is connected to the connecting plate 2, and the second tightening component 4 and the first tightening component 3 can be arranged at intervals along the length direction of the connecting plate 2, wherein the spacing between the second tightening component 4 and the first tightening component 3 is greater than the width of the bearing seat 5, and the bearing seat 5 can slide between the first tightening component 3 and the second tightening component 4 along the length direction of the connecting plate 2, and the second tightening component 4 has a movable second tightening end for contacting the other side of the bearing seat 5, that is, the second tightening end can contact the other side of the bearing seat 5 in an active state, for example, when the position of the bearing seat 5 on the connecting plate 2 changes, the second tightening end can contact the other side of the bearing seat 5 after being movable.

[0050] When the first tightening end and the second tightening end contact both sides of the bearing seat 5 at the same time, the first tightening component 3 and the second tightening component 4 clamp and fix the bearing seat 5, thereby realizing the positioning of the bearing seat 5 on the connecting plate 2, and further realizing the positioning of the screen roller 7.

[0051] The cross screen roller spacing adjustment mechanism provided in the present application is that after the screen roller 7 is slidably connected to the connecting plate 2 through the bearing seat 5, the position of the screen roller 7 relative to the connecting plate 2 is adjustable, so that when the screen rollers 7 wear each other, the screen rollers 7 can slide on the connecting plate 2 to adjust the spacing between the screen rollers 7, thereby ensuring the screening effect; wherein, after the position of the bearing seat 5 on the connecting plate 2 is adjusted, the bearing seat 5 is clamped and clamped by the first tightening assembly 3 and the second tightening assembly 4 to ensure the stability of the position of the bearing seat 5, thereby ensuring that the screening operation can be stably performed after the position of the screen roller 7 is adjusted.

[0052] In some optional embodiments, a sliding bar hole 21 is constructed on the connecting plate 2, and the length direction of the sliding bar hole 21 is parallel to the length direction of the connecting plate 2. The sliding bar hole 21 is used to cooperate with the connecting bolt 6 of the bearing seat 5; in actual implementation, the connecting bolt 6 on the bearing seat 5 is passed through the sliding bar hole 21 and then connected and cooperated with the bearing seat 5. The connecting bolt 6 plays a guiding role, and the bearing seat 5 can slide along the length direction of the connecting plate 2 under the guiding action of the connecting bolt 6. When the position of the bearing seat 5 in the length direction of the connecting plate 2 is adjusted into place, the bearing seat 5 and the connecting plate 2 can be relatively fixed by locking the connecting bolt 6. The clamping effect of the first tightening component 3 and the second tightening component 4 can make the position of the bearing seat 5 on the connecting plate 2 more stable, thereby ensuring the stability of the position and posture of the screen roller 7.

[0053] In some optional embodiments, the first tightening assembly 3 includes a first tightening seat 31 and a tightening bolt 32; the first tightening seat 31 is connected to the connecting plate 2, the first tightening seat 31 can be constructed as a block and welded to the connecting plate 2, a tightening screw hole is constructed on the first tightening seat 31, and the axis of the tightening screw hole is parallel to the length direction of the connecting plate 2; the tightening bolt 32 is threadedly matched with the first tightening seat, so that when the tightening bolt 32 is rotated, the tightening bolt 32 as a whole can move in the length direction of the connecting plate 2, and then the head of the tightening bolt 32 as the first tightening end can contact one side of the bearing seat 5. Preferably, the tightening bolt 32 can be configured as a hexagon socket bolt.

[0054] In some optional embodiments, the second tightening assembly 4 includes a second tightening seat 41, a tightening piece 42 and an operating piece 43; the second tightening seat 41 is connected to the connecting plate 2, and the second tightening seat 41 can also be constructed as a block and welded to the connecting plate 2; the tightening piece 42 is slidably connected to the second tightening seat 41, and the sliding direction of the tightening piece 42 is parallel to the length direction of the connecting plate 2, and the second tightening end is located at the tightening piece 42; the operating piece 43 is movably connected to the second tightening seat 41 and connected to the tightening piece 42; wherein, when the operating piece 43 is controlled to move, it can drive the tightening piece 42 to slide on the second tightening seat 41.

[0055] In some optional embodiments, the operating member 43 may include an operating rod 431 and a tightening wedge 432; the operating rod 431 is threadedly connected to the second tightening seat 41, and the length direction of the operating rod 431 is orthogonal to the length direction of the connecting plate 2; the tightening wedge 432 is connected to the operating rod 431 and contacts the tightening member 42 through the wedge surface, so that when the tightening wedge 432 and the tightening member 42 slide relative to each other, the tightening member 42 can move in the length direction of the connecting plate 2, and then the second tightening end on the tightening member 42 can contact the other side of the bearing seat 5; wherein the tightening member 42 is elastically slidably connected to the second tightening seat 41.

[0056] In the implementation of this application, the second tightening assembly 4 is located between the two bearing seats 5. Since the two screen rollers 7 are arranged crosswise, the spacing between the two bearing seats 5 is small, and the operating space for the staff in the length direction of the connecting plate 2 is small. Through the setting of the operating rod 431 and the tightening wedge block 432, the staff can operate from above the second tightening seat 41, the operating space is larger, and the operation is more convenient.

[0057] In some optional embodiments, the wedge surfaces on the top tightening wedge block 432 are configured to be two, the two wedge surfaces face opposite to each other, the number of the top tightening members 42 is configured to be two, and the two wedge surfaces are in contact with the two top tightening members 42 respectively. Therefore, when the top tightening wedge block 432 is driven to move by the operating rod 431, the two top tightening members 42 can move simultaneously in the length direction of the connecting plate 2, and the midpoint position of the two second top tightening ends remains unchanged, so that the centering of the two screen rollers 7 after adjustment can be ensured, that is, the axes of the two screen rollers 7 can always be symmetrical about the proposed center line. At the same time, the number of the second top tightening assembly 4 can be configured to be one.

[0058] In some optional embodiments, the top tightening wedge block 432 can be configured as a conical top block.

[0059] In some optional embodiments, the tightening wedge 432 may be rotatably connected to the operating rod 431. That is, the tightening wedge 432 does not have to rotate with the operating rod 431. In this case, the tightening wedge 432 may be formed by machining a wedge surface structure with a square block, and a square cavity for sliding the tightening wedge 432 is constructed on the corresponding second tightening seat 41, wherein the ends of the two tightening members 42 are located in the square cavity to contact the tightening wedge 432.

[0060] In some optional embodiments, the end of the tightening member 42 that contacts the tightening wedge block 432 is constructed as a wedge surface structure, which will facilitate the relative sliding of the tightening wedge block 432 and the tightening member 42.

[0061] In some optional embodiments, the tightening member 42 cooperates with the axial hole of the second tightening seat 41 , and a compression spring is connected between the tightening member 42 and the second tightening seat 41 .

[0062] In the second aspect, the present application provides a screening machine, comprising the above-mentioned cross screen roller spacing adjustment mechanism and a screen roller 7; two screen rollers 7 are arranged crosswise; wherein the bearing seat 5 of the screen roller 7 is connected to the cross screen roller spacing adjustment mechanism, and the bearing seat 5 is located between the first tightening component 3 and the second tightening component 4. Specifically, the second tightening component 4 is located between the two bearing seats 5, and the two first tightening components 3 are located on both sides of the cross screen roller as a whole, that is, two first tightening components 3 and one second tightening component 4 are connected to the connecting plate 2.

[0063] The screening machine provided in the present application, by providing a cross screen roller spacing adjustment mechanism, does not need to be replaced when the screen roller 7 is worn, thus reducing maintenance costs and simplifying the maintenance process, thereby reducing the labor intensity of maintenance personnel.
