[0034] like Figure 1 As shown, the utility model provides a plasticizing and cutting machine, comprising:

[0035] Rack 100;

[0036] A squeezing roller group 200, wherein the squeezing roller group 200 comprises two squeezing rollers 210, and the two squeezing rollers 210 are rotatably arranged on the frame 100 in parallel and at intervals;

[0037] A double-roller cutting mechanism 300, the double-roller cutting mechanism 300 comprises two cutting rollers 310 parallel to the squeezing roller 210, the two cutting rollers 310 are detachably rotatably arranged on the frame 100, and the two cutting rollers 310 are correspondingly located below the two squeezing rollers 210; the roller surfaces of the two cutting rollers 310 are each provided with a plurality of annular cutters 320 arranged at intervals, and the annular cutters 320 of the two cutting rollers 310 correspond one to one;

[0038] The driving assembly 400 is connected to the squeezing roller group 200 and the double-roller cutting mechanism 300 in a transmission manner to drive the two squeezing rollers 210 to rotate inwardly toward each other and to drive the two cutting rollers 310 to rotate inwardly toward each other.

[0039] In actual application, the prepared raw materials are fed between the two squeezing rollers 210, so that the components in the raw materials enter the space occupied by other components without chemical changes, and are evenly distributed in the matrix polymer, ensuring that the properties of each part of the rubber material are consistent, thereby forming a sheet of rubber material. After the sheet of rubber material is formed, it can be placed in the double-roller cutting mechanism 300 under the squeezing roller group 200, and the annular cutters 320 on the two cutting rollers 310 will cut the sheet of rubber material into a film of the required width. Among them, the width of the film depends on the interval between adjacent annular cutters 320 on the same cutting roller 310.

[0040] In the utility model, by arranging a double-roller cutting mechanism 300 under the extrusion roller group 200, the raw materials can be extruded and plasticized into sheet-like rubber materials, and the sheet-like rubber materials can be cut into required films. There is no need to transport the extruded and plasticized materials to other workshops or workstations for cutting, which effectively improves production efficiency.

[0041] In addition, the double-roller cutter mechanism 300 is assembled on the frame 100 in a detachable connection mode, so that the double-roller cutter mechanism 300 is replaceable. In this way, when a film of another width is needed, the double-roller cutter mechanism 300 on the frame 100 can be replaced, thereby improving the practicality of this device.

[0042] Specifically, the rack 100 includes two bracket portions 110 disposed at intervals, and a mounting slot 111 is provided on the same side of the two bracket portions 110; specifically, in some optional embodiments, such as Figure 1 As shown, the two bracket parts 110 are in a plate-shaped structure, and the two squeezing rollers 210 and the two cutting rollers 310 are between the two bracket parts 110 .

[0043] The double-roller cutting mechanism 300 further includes two plug-in parts 330, one end of the two cutting rollers 310 is rotatably connected to one of the plug-in parts 330, and the other end of the two cutting rollers 310 is rotatably connected to the other plug-in part 330;

[0044] The two plug-in parts 330 are installed in the installation slots 111 on the corresponding side and are detachably connected to the bracket part 110 on the corresponding side.

[0045] In this embodiment, the double-roller cutter mechanism 300 can be installed on the frame 100 by inserting its plug-in portion 330 into the installation slot 111. When the double-roller cutter mechanism 300 needs to be disassembled, the plug-in portion 330 is pulled out from the installation slot 111, and the double-roller cutter mechanism 300 can be completely removed from the frame 100. The disassembly and assembly of the double-roller cutter mechanism 300 is convenient, and the replacement of the double-roller cutter mechanism 300 is also convenient.

[0046] Preferably, if Figure 2 As shown, the bracket portion 110 is provided with a slope surface 112 at the bottom of the slot of the installation slot 111. In this way, the slot of the installation slot 111 becomes larger, so that the plug-in portion 330 can be inserted into the installation slot 111.

[0047] Specifically, the frame 100 also includes an installation locking assembly 120, which includes a gasket 121 and a top screw 122. The gasket 121 is connected to a first vertical portion 1211, an inclined portion 1212, and a second vertical portion 1213 in sequence from top to bottom. The inclined portion 1212 is fitted and abutted against the slope surface 112. The first vertical portion 1211 is abutted against the plug-in portion 330. The second vertical portion 1213 is abutted against the side wall of the bracket portion 110. The top screw 122 passes through the second vertical portion 1213 and is threadedly fixed to the bracket portion 110 to lock the second vertical portion 1213.

[0048] In this embodiment, after the plug-in portion 330 is inserted into the installation slot 111, the first vertical portion 1211 of the gasket 121 is used to abut the plug-in portion 330, the inclined portion 1212 of the gasket 121 abuts against the slope surface 112, and the second vertical portion 1213 of the gasket 121 abuts against the side wall of the bracket portion 110. Then, the top screw 122 is passed through the reserved through hole of the second vertical portion 1213 and is threadedly connected to the bracket portion 110 to fix the gasket 121, so that the plug-in portion 330 is clamped in the installation slot 111. When the plug-in portion 330 needs to be removed, the plug-in portion 330 can be removed by removing the top screw 122 and the gasket 121, so that the double-roller cutting mechanism 300 can be taken out for replacement. In this embodiment, the double-roller cutter mechanism 300 is clamped and limited by the gasket 121 and the top screw 122, so that the double-roller cutter mechanism 300 can be easily disassembled and assembled, and then replaced.

[0049] like Figure 3 As shown, the driving assembly 400 includes a driving motor, a first double gear 410, a first gear 420, a second double gear 430 and a second gear 440; the first double gear 410 is arranged at the end of the rotating shaft of the squeezing roller 210; the first gear 420 is arranged at the end of the rotating shaft of the other squeezing roller 210; the first gear 420 is meshed with the pinion part of the first double gear 410; specifically, the ends of the rotating shafts on the same side of the two squeezing rollers 210 pass through the bracket part 110 and are connected to the corresponding first double gear 410 and the first gear 420. The second double gear 430 is arranged at the end of the rotating shaft of one of the cutting rollers 310; the second gear 440 is arranged at the end of the rotating shaft of the other cutting roller 310; specifically, the ends of the rotating shafts on the same side of the two cutting rollers 310 pass through the plug-in part 330 and are connected to the corresponding second double gear 430 and the second gear 440. The second gear 440 is meshed with the small gear portion of the second double gear 430; the large gear portion of the first double gear 410 is meshed with the large gear portion of the second double gear 430, wherein the first double gear 410 and the second double gear 430 are diagonally distributed, and the first gear 420 and the second gear 440 are diagonally distributed; the output end of the drive motor is connected to the rotating shaft of any one of the squeezing rollers 210 or the rotating shaft of any one of the cutting rollers 310.

[0050] Specifically, refer to Figure 3In one embodiment shown, a driving motor is connected to a squeezing roller 210 equipped with a first double gear 410 to drive the squeezing roller 210 to rotate in a clockwise direction. Since the pinion of the first double gear 410 meshes with the first gear 420, the first gear 420 rotates in a counterclockwise direction. In this way, the two squeezing rollers 210 rotate inwardly toward each other, thereby squeezing the raw material between the two squeezing rollers 210. Since the large gear of the first double gear 410 meshes with the large gear of the second double gear 430, the second double gear 430 rotates in a counterclockwise direction. At the same time, the second double gear 430 drives the second gear 440 to rotate in a clockwise direction through the pinion. In this way, the two cutting rollers 310 rotate inwardly toward each other, thereby cutting the film passing through. In this embodiment, only one driving motor is needed to drive the two squeezing rollers 210 and the two cutting rollers 310 to rotate, which can effectively reduce the cost of the device.

[0051] Optionally, the device further comprises a material discharge mechanism, the material discharge end of which is located above the extrusion roller set 200. Thus, the material discharge mechanism directly delivers the material to the extrusion roller set 200 for extrusion and plasticization. In some optional embodiments, the material discharge mechanism may be a hopper.

[0052] Specifically, the unloading mechanism includes an unloading plate 500, which is tilted and arranged on the top of the frame 100, and the bottom edge of the unloading plate 500 is parallel to the axial direction of the extrusion roller group 200; the bottom edge of the unloading plate 500 is located directly above the two extrusion rollers 210. In a specific implementation, when the raw material falls on the unloading plate 500, the raw material rolls along the tilted unloading plate 500 to between the two extrusion rollers 210, thereby being extruded and plasticized. In this way, the raw material achieves a certain degree of dispersion effect when rolling on the tilted unloading plate 500, so that the raw material falls evenly in the extrusion rollers 210.

[0053] Preferably, both side edges of the blanking plate 500 are provided with a material blocking side plate 510, and the material blocking side plate 510 is arranged to be raised relative to the blanking plate 500. In this way, the raw material is effectively prevented from falling from both sides of the blanking plate 500, so that the raw material can fall smoothly between the two squeezing rollers 210.

[0054] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
