[0023] 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.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, this is the first embodiment of the utility model, which provides an automated double cone extrusion tablet press, including an extrusion mechanism 1, a frame 3 on the top of the extrusion mechanism 1, a conveying mechanism 2 on the top of the frame 3, a pneumatic cutter mechanism 4 on the outside of the frame 3, a sheet extrusion assembly 5 connected inside the frame 3, an adjusting structure 6 on the top of the frame 3, a glue-blocking assembly 7 located outside the sheet extrusion assembly 5 on the outside of the frame 3, and a pneumatic cylinder 8 on the top of the extrusion mechanism 1, with the outside of the pneumatic cylinder 8 connected to the frame 3.

[0026] The extrusion mechanism 1 includes a placement frame 101, a variable frequency motor 102 is provided on the top of the placement frame 101, a conical groove 103 is provided on the top of the placement frame 101 outside the variable frequency motor 102, a conical screw 105 is provided inside the conical groove 103, there are two conical screws 105, and gears 104 are provided on the outer side of each of the two conical screws 105. The ends of the conical screws 105 are connected to the outer side of the variable frequency motor 102, and a slide rail 106 is provided on the top of the extrusion mechanism 1.

[0027] The sheet extrusion assembly 5 includes a second variable frequency motor 501. The bottom of the second variable frequency motor 501 is connected to the top of the frame 3. The second variable frequency motor 501 drives a fixed roller 502. A movable roller 503 located on top of the fixed roller 502 is provided inside the frame 3. Both the movable roller 503 and the fixed roller 502 are provided with meshing gears on their outer sides.

[0028] When the operator processes the rubber and plastic compound, the material is placed inside the conical groove 103, and then the two conical screws 105 knead the material, turning it from powder and granules into a ball. At the same time, the two conical screws 105 push the material forward to the space between the fixed roller 502 and the movable roller 503, and then the rotation of the fixed roller 502 and the movable roller 503 presses the material into a sheet. The pneumatic cutting mechanism 4, the pitch adjustment structure 6 and the glue blocking assembly 7 process the material into sheets of the required size. Since the whole process is automated and does not require manual intervention, it reduces the workload of the operator and brings convenience to the operator.

[0029] By segmenting the process, the torque required by variable frequency motor 102 and variable frequency motor 501 is reduced, thereby reducing power consumption and significantly lowering energy costs.

[0030] Example 2

[0031] like Figures 2 to 5 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the conveying mechanism 2 includes a conveyor belt 201, the bottom of the conveyor belt 201 is connected to the top of the frame 3, and a pressure roller 202 is provided on the top of the conveyor belt 201.

[0032] The conveyor belt 201 facilitates the return of sheet materials with slightly different glue properties from the first dispensing to the conical groove 103, which is used to achieve multiple mixing to make the material more uniformly mixed and achieve the required performance standards, thereby improving product quality and reducing the workload of operators. The pressure roller 202 prevents the returned sheet materials from falling off the conveyor belt 201.

[0033] Among them, the frame 3 includes a connecting frame 301, and a pulley 302 is provided at the bottom of the connecting frame 301. The outer surface of the pulley 302 is adapted to the inside of the slide rail 106.

[0034] When the pneumatic cylinder 8 is activated, it drives the connecting frame 301 to move as a whole, and the pulley 302 moves inside the slide rail 106. The slide rail 106 limits the connecting frame 301 as a whole to prevent it from shifting position. This ensures that the sheet extrusion assembly 5 and the extrusion mechanism 1 can accurately merge and separate, so that a small amount of material that is not sticky enough may remain at this point. This makes it easier to clean up the residual material and brings convenience to the operator.

[0035] The frame 3 also includes a waste box 303, the bottom of which is connected to the top of the placement rack 101;

[0036] The waste box 303 facilitates the collection of residual material at the connection between the sheet extrusion assembly 5 and the extrusion mechanism 1 during cleaning, and also collects the cut-off scraps, making it convenient to clean up residual material during maintenance and cleaning.

[0037] The pneumatic cutting mechanism 4 includes a connecting plate 401 and a roller 404. The inner side of the connecting plate 401 is connected to the outer side of the frame 3. A movable block 402 is provided on the outer side of the connecting plate 401. A cutter 403 is provided at the bottom of the movable block 402. The inner side of the roller 404 is connected to the outer side of the frame 3. The roller 404 is located below the cutter 403.

[0038] The material is extruded into sheets by the sheet extrusion assembly 5. The extruded sheets are wound around the rollers 404 and cut at both ends by the cutter 403 to achieve the required size. By adjusting the distance between the cutters 403, it is easy to cut sheets of different widths. The material can be cut at the time of sheet output, which can save a process in the production of some materials, thereby improving production efficiency and saving costs.

[0039] Among them, the adjusting structure 6 includes a screw 601, the outer surface of the screw 601 is threadedly connected to the inside of the frame 3, a rotating rod 602 is provided at the top of the screw 601, and the bottom of the screw 601 is movably connected to the inside of the movable roller 503.

[0040] By rotating the rotary rod 602, the screw 601 is driven to rotate, thereby adjusting the distance between the movable roller 503 and the fixed roller 502, making it easier to extrude sheets of different thicknesses and improving the applicability of the equipment.

[0041] The adhesive blocking assembly 7 includes a mounting bracket 701, the inner side of which is connected to the outer side of the frame 3. A screw 702 is threaded inside the mounting bracket 701. A baffle 703 is provided inside the screw 702. A connecting rod 704 that penetrates the outside of the mounting bracket 701 is provided outside the baffle 703. A pressure plate 705 located above the mounting bracket 701 is provided on the outer side of the frame 3.

[0042] By rotating the screw 702, the baffle 703 is moved on the mounting frame 701, adjusting the distance between the baffle 703 and the movable roller 503 and the fixed roller 502, so that it can be used to extrude sheets of different lengths. The pressure plate 705 prevents the material extruded by the extrusion mechanism 1 from overflowing from the space between the baffles 703, which brings convenience to the operator.

[0043] Both variable frequency motor 102 and variable frequency motor 2501 are equipped with pressure sensors.

[0044] Through communication transmission via pressure sensors, the equipment automatically adjusts the speed of variable frequency motor 102 and variable frequency motor 501 according to the pressure level, without the need for manual intervention, saving labor costs. Furthermore, with pressure data control, the density of the material can also be increased.

[0045] Working principle and usage process of this utility model:

[0046] First, when the operator is mixing the materials, the materials are placed inside the conical groove 103, and then the variable frequency motor 102 is started. The gear 104 causes the two conical screws 105 to move relative to each other. As the two conical screws 105 rotate, the materials are kneaded from powder and granules into a ball, and the materials are kneaded tightly. The materials are pushed between the fixed roller 502 and the movable roller 503. At the same time, the start of the variable frequency motor 501 also drives the rotation of the fixed roller 502 and the movable roller 503. Then, the fixed roller 502 and the movable roller 503 press the materials into sheets. The sheets are cut by the cutter 403 at the sheet exit, which can save a process in the production of some materials, improve production efficiency and save costs. Thus, the whole process can be run automatically without manual intervention, which reduces the workload of the operators.

[0047] Furthermore, when it is necessary to clean the residual material on the equipment, the pneumatic cylinder 8 is activated, which drives the connecting frame 301 to move along the slide rail 106 via the pulley 302, thereby separating the frame 3 and the extrusion mechanism 1 as a whole, expanding its operating space, and thus facilitating the cleaning of residual material.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. 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.
