Detailed Implementation

[0021] 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.

[0022] Example 1

[0023] like Figures 1 to 5 As shown, this is the first embodiment of the utility model, providing a compact 18-inch open mill, including a frame 1, a roller assembly 2 on the top of the frame 1, a brake mechanism 3 located outside the roller assembly 2 on the top of the frame 1, an adjusting structure 4 on the top of the frame 1 connected to the roller assembly 2, a cover plate 5 on the top of the frame 1, rubber-blocking assemblies 6 on both sides of the cover plate 5, a material-turning structure 9 on the top of the cover plate 5, a cutting assembly 7 located below the roller assembly 2 on the inner side of the frame 1, a temperature control display screen 8 on the outer side of the cover plate 5, and an electrical box 10 on the outer side of the frame 1.

[0024] The roller assembly 2 includes a drive motor 201, the bottom of which is connected to the top of the frame 1. The drive motor 201 drives a brake disc 202. The shaft end of the brake disc 202 is connected to a gearbox 203 located on the right side of the top of the frame 1. The top of the frame 1 is provided with two rollers 204. The two rollers 204 are movably connected to the inner wall of the frame 1 and fixedly connected to the inner wall, respectively. The shaft ends of the two rollers 204 are provided with mutually meshing gears 205. The shaft ends of the rollers 204 are connected to the gearbox 203.

[0025] By placing the drive motor 201 and brake mechanism 3 behind the gear 205, the overall footprint of the open mill is reduced. At the same time, by starting the drive motor 201, the brake disc 202 is rotated, and the rotation speed is adjusted by the gearbox 203, so that the sheet production efficiency can be reasonably controlled. Meanwhile, the output shaft of the gearbox 203 is connected to the fixed roller 204, and through the meshing between the gears 205, the two rollers 204 are driven to move towards each other, which facilitates the pressing of the mixed material between the two rollers 204 into sheets, thus completing the sheet processing. Therefore, by compactly designing and assembling the drive motor 201 and brake mechanism 3, the length of the machine and the floor space are reduced, the utilization rate of the workshop area is improved, and the workshop layout is easier to plan.

[0026] Both rollers are made of chilled cast iron centrifugally cast on the outer side, which has high strength and wear resistance, effectively enhancing the shear force and friction on the material and promoting rapid and uniform mixing of the material.

[0027] Example 2

[0028] like Figure 2 and Figure 4 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the brake mechanism 3 includes a protective box 301. The bottom of the protective box 301 is connected to the top of the frame 1. A brake assembly 302 located outside the brake disc 202 is provided inside the protective box 301.

[0029] When a hazard occurs during the operation of the open mill, the brake assembly 302 is activated. The brake assembly 302 brakes the rotating brake disc 202, causing the roller 204 to stop rotating quickly. This prevents injury to the operator and avoids the inability to stop the equipment immediately due to inertia, thus preventing greater damage and improving the safety of the operator.

[0030] Among them, the adjustable distance structure 4 includes a power motor 401, the outside of which is connected to the outer wall of the frame 1, the power motor 401 drives the internal threaded pipe 402, the internal threaded pipe 402 is threaded with a threaded rod 403, and the other end of the threaded rod 403 is connected to the outside of the roller 204.

[0031] By starting the power motor 401, the internal threaded tube 402 is rotated, and then the movable roller 204 is moved away from the roller 204 fixed on the frame 1 through the thread between the internal threaded tube 402 and the threaded rod 403. This creates a larger gap between the two rollers 204, which makes it easier for the operator to process sheets of different thicknesses and brings convenience to the operator.

[0032] Among them, the glue-blocking assembly 6 includes a second cylinder 601, the inner side of the second cylinder 601 is connected to the outer side of the cover plate 5, the inner side of the second cylinder 601 passes through the cover plate 5 and is provided with a baffle 602, and the bottom of the baffle 602 is movably connected to two rollers 204.

[0033] By activating cylinder 601, the baffle 602 is moved between the two rollers 204, thereby adjusting the position of the baffle 602 on the rollers 204. This allows for the production and processing of sheet materials of different widths. The baffle 602 and the adjusting structure 4 also improve the practicality of the equipment.

[0034] Among them, a limiting rod 603 is provided on the outer side of the baffle 602, the limiting rod 603 passes through the cover plate 5 and extends to the outside, and a protective plate 604 is provided on the inner side of the cover plate 5 above the two rollers 204.

[0035] When the baffle 602 moves, it drives the limiting rod 603 to move inside the cover plate 5. The limiting rod 603 is used to limit the baffle 602 to prevent it from shifting position. At the same time, when the material is pressed into tablets, the protective plate 604 prevents the material from entering the shaft ends on both sides of the two rollers 204, so as to avoid the material affecting the operation of the two rollers 204. One set of protective plates 604 is fixed inside the cover plate 5, and the other set of protective plates 604 is movably set on the cover plate 5 so that it can move with the moving rollers 204 and always provide protection.

[0036] The cutting assembly 7 includes a cutting blade structure 701, the outer side of which is connected to the inner wall of the frame 1. A waste hopper 702 located below the two rollers 204 is provided on the top of the frame 1, and a collection box 703 is provided at the bottom of the waste hopper 702.

[0037] The cutting structure 701 is used to cut the sheet material extruded by the two rollers 204, so that the processed sheet material is of regular size. At the same time, the cut material falls into the waste hopper 702. After processing, it is neatly placed into the collection box 703, so that the operator can collect and process the cut material.

[0038] Among them, the outside of the electrical box 10 is provided with a rocker arm, which is connected to the cover plate 5;

[0039] The rocker arm on the outside of the electrical box 10 makes it easy for operators to position the electrical box 10 and facilitates its operation. At the same time, the electrical box 10 is equipped with a photoelectric monitoring system, which can monitor the operation in real time. When there is a danger or safety risk from the operation, the equipment can automatically stop, which improves the safety of the operators. In addition, the temperature control display screen 8 is used to monitor the temperature of the roller 204 in real time to avoid the roller 204 from overheating or the temperature not meeting the standard, so as to prevent the processing quality of the sheet material from being affected.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0041] 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.
