[0028] The present utility model provides a locking frame for preventing loosening of a sheet press, including;

[0029] The bottom plate 1 is a movable bottom plate;

[0030] Two pairs of moving wheels are rotatably installed on the lower end surface of the bottom plate 1, which can facilitate the transfer of the bottom plate 1;

[0031] The first N-shaped frame 2 is fixedly installed on the upper end surface of the bottom plate 1;

[0032] The first rotating roller 3 is rotatably installed in the first N-shaped frame 2;

[0033] A driving motor is fixedly installed on one side wall surface of the first N-shaped frame 2, and the output end of the driving motor is fixedly connected to one end of the first rotating roller 3, which can drive it to rotate;

[0034] The second N-shaped frame 4 is arranged in the first N-shaped frame 2 and is located above the first rotating roller 3;

[0035] The second rotating roller 5 is rotatably installed in the second N-shaped frame 4;

[0036] A cylinder is fixedly installed in the upper wall of the first N-shaped frame 2, and the telescopic end of the cylinder is fixedly connected to the upper end surface of the second N-shaped frame 4, which can drive the second N-shaped frame 4 and the second rotating roller 5 to rise or fall. When descending, it approaches the first rotating roller 3 and cooperates with the first rotating roller 3 to press the rubber sheet;

[0037] The locking device is arranged in the first N-shaped frame 2 and is used to lock the second N-shaped frame 4.

[0038] Specifically, the locking device includes;

[0039] A pair of first sleeves 6 are both fixedly installed in the upper wall of the first N-shaped frame 2;

[0040] The second sleeve 7 is slidably installed in the first sleeve 6, and the bottom end contacts the upper end surface of the second N-shaped frame 4;

[0041] The screw rod 8 is arranged in the first sleeve 6, one end of which is threadedly connected to the second sleeve 7, and the other end rotatably penetrates the upper wall of the first sleeve 6;

[0042] The rotation of the screw rod 8 can drive the second sleeve 7 to slide downward, and at the same time, its bottom end contacts the upper end surface of the second N-shaped frame 4, which can hold it against, preventing the telescopic end of the cylinder from contracting due to long-term use during the rubber sheet pressing by the first rotating roller 3 and the second rotating roller 5, resulting in the upward movement of the second N-shaped frame 4 and the rotating roller 5 and affecting the rubber sheet pressing effect;

[0043] The driving mechanism is arranged on the upper end surface of the first N-shaped frame 2 and is used to drive the screw rod 8 to rotate.

[0044] Specifically, the driving mechanism includes;

[0045] The fixing blocks 9, with a pair in number, are both fixedly installed on the upper end surface of the first N-shaped frame 2;

[0046] The worm 10 is rotatably installed between a pair of fixing blocks 9;

[0047] The worm gear 11 is fixedly installed at the top end of the screw rod 8 and is meshed with the worm 10;

[0049] The driving component 12 is a motor, and its rotating output end can drive the worm 10 to rotate. The rotation of the worm 10 can drive a pair of worm gears 11 to rotate simultaneously. The rotation of a pair of worm gears 11 can respectively drive a pair of screw rods 8 to rotate. At this time, the rotation of a pair of screw rods 8 can drive a pair of second sleeves 7 to slide out of the first sleeve 6, and at the same time, their bottom ends contact the upper wall surface of the second N-shaped frame 4.

[0050] Specifically, a limiting groove 13 is formed on the inner wall surface of the first sleeve 6, and a limiting block 14 slidably connected to the limiting groove 13 is fixedly installed on the outer surface of the second sleeve 7;

[0051] Under the action of the limiting groove 13 and the limiting block 14, the second sleeve 7 can be stably slid out of the first sleeve 6 to prevent the second sleeve 7 from rotating along with the screw rod 8 during the rotation of the screw rod 8.

[0052] Specifically, a sliding groove 15 is formed on the inner side wall surface of the first N-shaped frame 2, and a sliding block 16 slidably connected to the sliding groove 15 is fixedly installed on the outer side wall surface of the second N-shaped frame 4;

[0053] Under the action of the sliding groove 15 and the sliding block 16, the second N-shaped frame 4 can slide more stably within the first N-shaped frame 2.

[0054] Working principle: When it is necessary to press the rubber into sheets, the staff first start the cylinder. The telescopic end of the cylinder extends, which can drive the second N-shaped frame 4 and the second rotating roller 5 to move downward, making the second rotating roller 5 approach the first rotating roller 3. At the same time, the staff move the second rotating roller 5 to a predetermined position according to the required thickness of the rubber sheet. At this time, the staff start the driving component 12. The rotation of the output end of the driving component 12 can drive the worm 10 to rotate. The rotation of the worm 10 can drive a pair of worm wheels 11 to rotate simultaneously. The rotation of a pair of worm wheels 11 can drive a pair of screw rods 8 to rotate respectively. At this time, the rotation of a pair of screw rods 8 can drive a pair of second sleeves 7 to slide out of the first sleeve 6, and at the same time, their bottoms contact the upper wall surface of the second N-shaped frame 4, resisting the second N-shaped frame 4 and limiting its position. At this time, the staff start the driving motor. The rotation of the output end of the driving motor can drive the first rotating roller 3 to rotate. At this time, with the cooperation of the second rotating roller 5, the rubber can be processed into sheets, which brings convenience to people.
