Description

Technical Field

[0001] This utility model relates to the field of open mill technology, specifically to an open mill pressing device for producing barbell plates for fitness equipment. Background Technology

[0002] The open mill mainly consists of rollers, a frame, a gap adjustment device, and a transmission device. Material is drawn into the gap between two counter-rotating rollers at different linear velocities under the action of friction. The material passing through the roller gap undergoes intense shearing and compression, causing the material temperature to rise and its plasticity to increase, thus achieving the purpose of rubber compounding. It is used for plasticizing, mixing, tableting, and hot refining operations.

[0003] Most modern open mixing mills require workers to manually mix and tumble the materials. Workers' hands are easily caught in the rotating rollers, posing a safety hazard. Furthermore, feeding is also done manually, which also poses a safety hazard to workers. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a pressing device for a two-roll mill used in the production of barbell plates for fitness equipment, including a base 1, a workbench 101 on the top of the base 1, movable holes 104 on both sides of the workbench 101, a fixing block 106 at the front end of the movable hole 104, a motor 201 installed in the left fixing block 106, a fixing plate 102 fixedly connected to the outside of the motor 201, a front roller 2 connected to the front output shaft of the motor 201, a tilting plate 7 connected to the outside of the front roller 2, a sliding rod 701 at the front end of the tilting plate 7, and a slide rail 10 at the end of the sliding rod 701 away from the tilting plate 7. 3. A movable block 105 is installed at the rear end of the movable hole 104. A motor 301 is installed inside the movable block 105 on the right side. The output shaft of the motor 301 is connected to the rear roller 3. A movable plate 107 is fixedly connected to the outside of the motor 301. A slide rail 108 is connected to the end of the movable plate 107 away from the motor 301. A hydraulic device 6 is provided at the rear end of the worktable 101. A limit plate 4 is fixedly connected to the front end of the hydraulic device 6. Movable holes 401 are opened at the front ends of both sides of the limit plate 4. Fixed holes 402 are opened at the rear ends of both sides of the limit plate 4. An installation hole 403 is opened at the top of the limit plate 4. A feed hopper 5 is installed in the installation hole 403.

[0022] Furthermore, the rear end of the limiting plate 4 is a structure of two non-concentric semicircles, and both semicircles are tangent to the bottom inner side of the worktable 101.

[0023] The above technical solution ensures that the material is confined between the worktable 101 and the limiting plate 4 during the pressing process, and no overflow occurs.

[0024] Furthermore, the output shaft of motor 201 passes through movable hole 401, and the output shaft of motor 301 passes through fixed hole 402.

[0025] Through the above technical solution, the hydraulic device 6 can drive the motor 301 and the rear roller 3 to move together when pushing the limit plate 4, without causing the front roller 2 to move.

[0026] Furthermore, the slide rail 2 108 and the movable hole 2 401 provide the same displacement distance for the movable plate 107 and the motor 2 301, respectively.

[0027] The above technical solution ensures that the movable plate 107 and the motor 301 will not be unable to move due to insufficient length of either the slide rail 108 or the movable hole 401.

[0028] Furthermore, the rear end of the flipping plate 7 has a semi-circular structure, and the arc surface of the semi-circular structure coincides with the surface of the front roller 2.

[0029] The above technical solution makes it easy for the material turning plate 7 to squeeze all the material on the front roller 2 together during the material turning process, so that no material is left out.

[0030] Working principle: First, start motor 201 and motor 301. Motor 201 and motor 301 drive the front roller 2 and rear roller 3 to rotate. Then, the material is poured into the limiting plate 4 through the feed hopper 5. The front roller 2 and rear roller 3 continuously squeeze the material within the limiting plate 4. During the squeezing process, different materials can be added through the feed hopper 5. When it is necessary to turn the material over, the two turning plates 7 on both sides can be moved to squeeze the material. After squeezing, the material continues to be squeezed by the front roller 2 and rear roller 3 to fuse the different materials. Then, the distance between the front roller 2 and rear roller 3 can be reduced by the hydraulic device 6 to provide greater pressure to the material so that the different materials can be more fully fused. After all the materials have been squeezed and fused, they can be taken out.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
