Description

Technical Field

[0001] The utility model relates to the technical field of open mixing mills, in particular to an adjustable roller assembly of an open mixing mill. Background Art

[0002] A mixing mill is a rubber mixing machine with exposed rollers used in rubber factories to prepare plasticized rubber, mixed rubber, or for hot mixing and molding. The roller assembly of the mixing mill is used to calender and cut the roller part of rubber blocks or rubber mixtures.

[0003] The Chinese patent "A direct-connected open refining" authorization announcement number "CN217257493U" adjusts the distance between the two rollers through a rotating rod, a wheel disc, and an adjusting rod. The operation of adjusting the distance between the two rollers is simple.

[0004] However, when adjusting through the rotating rod, the wheel disc and the adjusting rod, the staff needs to repeatedly rotate the two rotating rods according to experience to adjust the position of the corresponding rollers, so as to adjust the distance between the two rollers, which makes the debugging process very cumbersome.

[0005] Therefore, an adjustable roller assembly of an open mixing mill is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an adjustable roller assembly for an open mixing mill in order to solve the above problems, thereby improving the problem of repeatedly rotating two rotating rods to adjust the positions of corresponding rollers.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: an adjustable roller assembly of an open mixing mill is used to be arranged on a workbench of the open mixing mill, and the adjustable roller assembly comprises a screw rod and a debugging mechanism.

[0008] Both sides of the inner wall of the workbench are rotatably connected to the screw rod;

[0009] The above-mentioned debugging mechanism is used to adjust the distance between the two rollers, and the debugging mechanism is arranged on the surface of the workbench;

[0010] Wherein, the debugging mechanism includes a gear fixedly connected to one end of the screw rod, the surface of the gear is meshingly connected with a rack, and the surface of the workbench is provided with a debugging component.

[0011] Preferably, the debugging component includes a connecting frame fixedly connected to the bottom of the rack, and a pulling block is fixedly connected to one side of the connecting frame. The movement of the pulling block drives the gear to rotate through the connecting frame and the rack. The rotation of the gear drives the roller on the mixing mill to move through the screw rod, which makes it more convenient to adjust the spacing of the roller assemblies of the mixing mill, and avoids the tediousness of repeatedly driving the two screw rods to rotate to adjust the spacing of the roller assemblies.

[0012] Preferably, a limiting rod is provided on one side of the rack, and a limiting block is fixedly connected to one side of the rack. The inner wall of the limiting block is slidably connected to the surface of the limiting rod. The limiting block and the limiting rod limit the moving rack to prevent the rack from deviating during movement.

[0013] Preferably, the surface of the limit rod is provided with positioning grooves distributed in equal rows, and a positioning rod is clamped on the inner wall of one of the positioning grooves, and the front end of the limit block is fixedly connected to a positioning cylinder, the surface of the positioning rod is slidably connected to the inner wall of the positioning cylinder, one end of the positioning rod passes through and extends out of the surface of the limit block, and one end of the positioning rod is fixedly connected to a spring, and one end of the spring is fixedly connected to one end of the inner wall of the positioning cylinder. The elastic force of the spring pushes the positioning rod to move in the limit block and clamp it into the corresponding positioning groove, thereby positioning the limit block at the corresponding position on the limit rod to ensure the stability of the rack on the gear.

[0014] Preferably, one end of the positioning rod is fixedly connected to a moving rod, and one end of the moving rod passes through the positioning tube and is fixedly connected to a moving frame. The movement of the moving frame drives the two moving rods to move simultaneously, and the movement of the moving rod drives the positioning rod to move, thereby making the positioning rod move away from the corresponding positioning groove, and the operation of releasing the positioning state of the limit block on the limit rod is simple.

[0015] Preferably, one end of the limit rod is fixedly connected to a support block, and the rear end of the support block is fixedly connected to the front end of the workbench. The support block is used to support and limit the limit rod and to limit the moving limit block to prevent the limit block from detaching from the limit rod during movement.

[0016] The beneficial effects of the utility model are:

[0017] 1. Pull the moving frame, and the moving frame moves by driving the positioning rod to move away from the corresponding positioning groove, thereby releasing the positioning state of the limit block on the limit rod, and pulling the pull block. The pull block moves up and drives the two screws to rotate simultaneously through the connecting frame, rack and gear. The two screws rotate simultaneously to drive the corresponding rollers to move to the appropriate position on the workbench, which makes it more convenient to adjust the roller assembly spacing of the mixing mill, avoiding the tediousness of repeatedly driving the two screws to rotate to adjust the roller assembly spacing;

[0018] 2. The elastic force of the spring pushes the positioning rod to move, so that the positioning rod moves in the limit block and is snapped into the corresponding positioning groove, thereby positioning the limit block at the corresponding position of the limit rod, ensuring the stability of the rack on the gear and improving the stability of the roller at the corresponding position of the workbench.
