[0027] It should be noted that, the hand wheel 45 is rotated to drive the first screw rod 41 on the right side to rotate. The first screw rod 41 is a bidirectional screw rod having two threads in opposite directions. The two first movable seats 42 or the second movable seats 43 are respectively threadedly connected to the threads in different directions. When the first screw rod 41 on the right side rotates, it drives the two first movable seats 42 to move in the reverse direction in the front-to-back direction, and only the two rubber mixing rollers 44 move in the reverse direction in the front-to-back direction.

[0028] like Figure 3 As shown, first sprockets 46 are fixedly connected to the outer walls of the two first screw rods 41 near the rear ends, and the outer sides of the first sprockets 46 are meshedly connected to the first chains 47 .

[0029] It should be noted that when the first screw rod 41 on the right side rotates, it drives the first sprocket 46 on the right side to rotate, and relies on the first chain 47 to drive the first sprocket 46 on the left side to rotate, so that the two first screw rods 41 rotate synchronously in the same direction, causing the second movable seat 43 and the first movable seat 42 on the same side to move synchronously in the same direction, so that the left and right sides of the rubber mixing roller 44 are subjected to balanced force.

[0030] like Figure 3 , Figure 4As shown, the left end axes of the two rubber mixing rollers 44 are fixedly connected with a rotating assembly 48, and the rotating assembly 48 includes a first gear 481, the right side of the first gear 481 is fixedly connected to the left axis of the rubber mixing roller 44, the upper side of the first gear 481 is meshedly connected with the second gear 482, the right side axis of the second gear 482 is rotatably connected to the upper side of the second moving seat 43 near the right side of the boss, the left side axis of the second gear 482 is fixedly connected with a first bevel gear 483, the side of the first bevel gear 483 away from each other is meshedly connected with the second bevel gear 484, the side of the second bevel gear 484 away from each other is rotatably connected to the upper side of the second moving seat 43 near the front side, the first motor 49 is fixedly connected to the boss located in the middle of the front side of the vertical plate 3 on the left side, the output end of the first motor 49 is fixedly connected with a transmission rod 410, and the outer wall of the transmission rod 410 is movably sleeved on the inner side of the second bevel gear 484.

Since the two second bevel gears 484 are located on the side away from the two first bevel gears 483, the two first bevel gears 483 rotate synchronously in the same direction, causing the two rubber mixing rollers 44 to rotate synchronously in the opposite direction.

[0032] like Figure 1 , Figure 5 As shown, the guiding mechanism 5 includes a second motor 51, the lower side of the second motor 51 is fixedly connected to the horizontal plate located at the upper rear side of the right side surface of the right vertical plate 3, the output end of the second motor 51 is fixedly connected to the second screw rod 52, the outer wall of the second screw rod 52 is rotatably connected to the inner side of the vertical plate 3 near the upper rear side near the left and right ends, the side of the vertical plates 3 close to each other is rotatably connected to the rotating rod 54 near the upper front side, the outer wall of the second screw rod 52 is threadedly connected to the guide frame 53, and the front side of the guide frame 53 is rotatably connected to the outer wall of the rotating rod 54.

[0033] It should be noted that the second motor 51 drives the second screw rod 52 to rotate. The second screw rod 52 is a reciprocating screw rod having two threads connected end to end. When the second screw rod 52 rotates, it drives the guide frame 53 to reciprocate in the left and right directions. The rotating rod 54 is used to limit the guide frame 53 to prevent the guide frame 53 from rotating when the second screw rod 52 rotates.

[0034] like Figure 5As shown, the second screw rod 52 and the outer wall of the rotating rod 54 are fixedly connected to the second sprocket 55 near the right end, the side of the second sprocket 55 is meshingly connected to the second chain 56, and the side of the guide frame 53 close to each other is rotatably connected to the rotating roller 57 near the front side, and the inner side of the rotating roller 57 is movably sleeved on the outer wall of the rotating rod 54.

[0035] It should be noted that when the second screw rod 52 rotates, it drives the second sprocket 55 located on the rear side to rotate, and relies on the second chain 56 to cause the second sprocket 55 located on the front side to rotate, causing the rotating rod 54 to rotate. The rotation direction of the rotating rod 54 is backward. A limiting groove is provided on the outer wall of the rotating rod 54, and a sliding bar is provided on the inner side of the rotating roller 57 and is slidably connected in the limiting groove, so that the rotating rod 54 drives the rotating roller 57 to rotate synchronously, so as to reduce the friction between the rubber and the rotating rod 54, so that the rubber can smoothly slide down from the inner side of the guide frame 53.

[0036] The working principle of the utility model is as follows: first, the hand wheel 45 is rotated to drive the first screw rod 41 located on the right side to rotate. The first screw rod 41 is a bidirectional screw rod, which contains two threads in opposite directions. The two first movable seats 42 or the second movable seats 43 are respectively threadedly connected with threads in different directions. When the first screw rod 41 on the right side rotates, the two first movable seats 42 are driven to move in the reverse direction in the front-to-back direction, and only the two rubber mixing rollers 44 move in the reverse direction in the front-to-back direction. When the first screw rod 41 on the right side rotates, the first sprocket wheel 46 on the right side is driven to rotate. The first chain 47 drives the first sprocket 46 on the left side to rotate, so that the two first screw rods 41 rotate synchronously in the same direction, causing the second moving seat 43 and the first moving seat 42 on the same side to move synchronously in the same direction, so that the forces on the left and right sides of the rubber mixing roller 44 are balanced. By turning the hand wheel 45, the two rubber mixing rollers 44 move in the reverse direction in the front and back directions, so that the distance between the two rubber mixing rollers 44 is adjusted, so that when facing the rubber mixing task of different rubber amounts, it can be adjusted, so that the rubber mixing efficiency is higher and the operation is convenient. Finally, the second motor 51 The second screw rod 52 is driven to rotate. The second screw rod 52 is a reciprocating screw rod having two threads connected end to end. When the second screw rod 52 rotates, it drives the guide frame 53 to reciprocate in the left and right directions. The rotating rod 54 is used to limit the guide frame 53 to prevent the guide frame 53 from rotating oppositely when the second screw rod 52 rotates. When the second screw rod 52 rotates, it drives the second sprocket wheel 55 located at the rear side to rotate. The second chain 56 causes the second sprocket wheel 55 located at the front side to rotate, causing the rotating rod 54 to rotate. The rotating direction of the rotating rod 54 is backward. The outer wall of the rotating rod 54 is provided with a The limiting groove is provided with a sliding bar on the inner side of the rotating roller 57 which is slidably connected in the limiting groove, so that the rotating rod 54 drives the rotating roller 57 to rotate synchronously to reduce the friction between the rubber and the rotating rod 54, so that the rubber can smoothly slide down from the inner side of the guide frame 53, and the pressed rubber wrapped on the rubber mixing roller 44 is gathered and passed through the guide frame 53, so that the pressed rubber is stacked together again, and at the same time, the second motor 51 drives the second screw rod 52 to rotate, so that the gathered rubber is spread flat at every place between the rubber mixing rollers 44, thereby increasing the rubber mixing efficiency and shortening the rubber mixing time.
