DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a kneading machine for silica gel production, the kneading machine for silica gel production includes a kneading machine case 1, and also includes a case cover 2 hinged to the kneading machine case 1, a sealing ring 201 is fixedly connected to the case cover 2, and a plurality of limit seats 3 are connected to the side of the case cover 2 away from the hinge, the limit seats 3 are used to tighten and limit the case cover 2 and the kneading machine case 1, and a driving mechanism 4 for driving the limit seats 3 to move is installed on the case cover 2.

[0028] In the above technical scheme, when the box cover 2 is rotated to close with the kneading chassis 1, the sealing ring 201 fits with the opening table surface of the kneading chassis 1. When the limiting mechanism 4 is operated to drive each limiting seat 3 to move synchronously, the limiting seat 3 can bite and limit the box cover 2 and the kneading chassis 1 to achieve multi-point limiting and improve the sealing effect.

[0029] The driving mechanism 4 includes a driving rod 401 rotatably connected to the box cover 2, and a driving frame 403 is drivingly connected to the driving rod 401. Both ends of the driving frame 403 are hinged with a second connecting rod 406 through a first connecting rod 405. The second connecting rod 406 is used to drive the limit seat 3 to move.

[0030] In the above technical solution, when the driving rod 401 is rotated, the driving frame 403 can be driven to move horizontally. The driving frame 403 drives the connecting rod 2 407 to move horizontally through the connecting rod 1 406, so that the connecting rod 2 407 can drive the limit seat 3 to move, so that the limit seat 3 can bite the box cover 2 and the kneading chassis 1.

[0031] The limit seat 3 is in a U-shaped structure, and a slope 1 301 and a slope 2 302 are provided on both symmetrical sides of the limit seat 3, and a driving rod 303 is rotatably connected to the limit seat 3. The slope 1 301 has a large slope, which is convenient for the limit seat 3 to contact the edge of the box cover 2 and the kneading chassis 1 when the inner cavity of the limit seat 3 is docked with the box cover 2 and the kneading chassis 1. Then, when the limit seat 3 continues to bite with the box cover 2 and the kneading chassis 1, the box cover 2 and the kneading chassis 1 are gradually brought into close contact through the gently inclined slope 2 302.

[0032] A limit frame 404 is fixedly connected to the box cover 2, the driving frame 403 is slidably connected to the limit frame 404, and a fixed rod 402 is fixedly connected to the driving rod 401, the fixed rod 402 is slidably connected to the driving frame 403, the limit frame 404 limits the movement of the driving frame 403, and when the driving rod 401 rotates, the fixed rod 402 slides in the through hole of the driving frame 403 and drives the driving frame 403 to translate.

[0033] The fixing rod 402 is disposed on one side of the driving rod 401 close to the rotation part, so that when the driving rod 401 rotates and drives the fixing rod 402 to move, it is a labor-saving lever movement, which is convenient for driving the driving frame 403 to move.

[0034] The connecting rod 406 is slidingly connected to the box cover 2, and racks 407 are fixedly connected on both symmetrical sides of the connecting rod 406, and a gear 408 is meshedly connected to one side of the rack 407. The gear 408 is rotationally connected to the box cover 2, and the gear 408 is fixedly connected to the driving rod 303. The two connecting rods 407 are driven away from each other, so that the rack 407 drives the gear 408 to rotate, and the gear 408 and the driving rod 303 cooperate to drive the limit seat 3 to move toward the side close to the box cover 2 and the kneading chassis 1 until the limit seat 3 is engaged with the box cover 2 and the kneading chassis 1.

[0035] In some embodiments, reference Figure 4The moving direction of the connecting rod 407 is perpendicular to the moving direction of the driving frame 403. Fixed plates fixedly connected to the box cover 2 are provided on both sides of the connecting rod 407, and a guide wheel is connected to the side of the connecting rod 407 that rotates toward the fixed plate. The guide wheel is in rolling contact with the fixed plate, thereby improving the smoothness of the connecting rod 407 when moving.

[0036] A spring 1 409 is elastically connected between the two connecting rods 406. When the two connecting rods 407 move away from each other, the spring 1 409 is stretched. When the driving rod 401 rotates in the opposite direction, the spring 1 409 contracts to help drive the two connecting rods 407 to return to their original positions.

[0037] During use, after the box cover 2 rotates to drive the sealing ring 201 to fit the table top of the kneading chassis 1, the driving rod 401 is manually rotated clockwise, and the fixed rod 402 drives the driving frame 403 to move to the side of the connecting rod 2 407, and the driving frame 403 drives the connecting rod 2 407 to translate through the connecting rod 1 406. The two connecting rods 407 move away from each other, and the rack 407 drives the gear 408 to rotate. The gear 408 cooperates with the driving rod 303 to drive the limiting seat 3 to engage with the box cover 2 and the kneading chassis 1, and multiple limiting seats 3 cooperate to make the box cover 2 and the kneading chassis 1 fit tightly.

[0038] Example 2

[0039] Reference Figure 5 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the movable end of the driving rod 401 is slidably connected with the positioning rod 5, a spring 2 501 is elastically connected between the positioning rod 5 and the driving rod 401, a positioning seat 6 is fixedly connected to the box cover 2, and the positioning rod 5 and the positioning seat 6 are plugged together.

[0040] In the above technical solution, one end of the positioning rod 5 close to the positioning seat 6 is round-headed, and the positioning seat 6 has a symmetrical clearance surface on the side facing the positioning rod 5. When the round head end of the positioning rod 5 contacts the clearance surface, the positioning rod 5 slides into the driving rod 401 and compresses the spring 2 501. When the axis of the positioning rod 5 coincides with the axis of the positioning hole opened on the positioning seat 6, the spring 2 501 extends and drives the positioning rod 5 to move to connect with the positioning seat 6, thereby limiting the rotation of the driving rod 401.

[0041] By pushing the positioning rod 5 toward one side of the driving rod 401 , when the positioning rod 5 is not plugged into the positioning seat 6 , the rotation restriction on the driving rod 401 can be cancelled, and the driving rod 401 can be driven to rotate again.

[0042] The remaining structures are the same as those of Example 1.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
