[0035] The following description provides specific application scenarios and requirements for this specification, intended to enable those skilled in the art to make and use the contents of this specification. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "longitudinal", "lateral", "radial", "length", "width", "thickness", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element or component to have a specific orientation, or to be constructed and operated in a specific orientation.

[0037] Secondly, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different components and should not be construed as limiting the embodiments of this application.

[0038] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two devices, components, or parts.

[0039] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.

[0041] like Figures 1 to 11 As shown in the figure, this specification provides a sheet forming machine for processing plastic granules into sheets, which includes a feeding device 1, a heating tube 2, a filtering device 3, a metering pump 4, a forming frame 5, a shaping device 6, a conveying frame 7, a cutting device 8, and a winding device 9.

[0042] The feeding device 1 is used to automatically feed plastic granules to the heating tube 2. Generally, a feeding device 1 commonly used in the art is adopted, such as a feeding funnel. As long as plastic granules are added into the feeding funnel, the feeding funnel can continuously convey plastic granules to the heating tube.

[0043] The heating tube 2 is used to plasticize the plastic particles. Plasticization refers to the entire process in which the plastic is heated in the barrel to reach a flowable state and has good plasticity.

[0044] like Figures 3 to 5 As shown, the filtration device 3 includes a housing 30, a filter frame 31, and a driver. The filter frame 31 is slidably disposed within the housing 30 and has at least two channels 32. An isolation part 33 is provided between adjacent channels 32. A filter cartridge 34 is disposed within each channel 32. Several positioning grooves 35 are provided circumferentially on the inner wall of the channel 32. Positioning blocks 36 are provided on the outer wall of the filter cartridge 34 corresponding to the positioning grooves 35. Preferably, three positioning grooves 35 are provided circumferentially on the inner wall of the channel 32. The end of the positioning groove 35 near the liquid inflow penetrates the channel 32, and the other end is closed. In this way, the filter cartridge 34 can be fixed within the channel 32 when the liquid flows. Openings 37 are provided on both sides of the housing 30 for replacing the filter cartridge 34.

[0045] The actuator drives the filter holder 31 to move, allowing each channel 32 to connect to the heating tube 2. During the switching process, the isolation part 33 seals the heating tube 2 to prevent leakage. When the heating tube 2 is connected to the channel 32, the filter cartridge 34 inside the channel 32 can filter the liquid plastic. Meanwhile, the channels 32 not connected to the heating tube 2 will be exposed at their openings. At this time, the filter cartridge 34 can be easily removed from the channel 32 for replacement or cleaning.

[0046] The driver can be a motor, cylinder, etc. Optionally, a slide rail and slider structure can be provided between the filter frame 31 and the housing 30.

[0047] In some embodiments, the filter cylinder 34 is provided with at least one filter screen along its axial direction, and if multiple filter screens are provided, the mesh size of each filter screen is different, for example, decreasing sequentially along the conveying direction, forming a graded filtration. Of course, they can also be of the same size, which can also achieve multiple filtration.

[0048] In some embodiments, the filtration effect of the filter cartridges 34 in different channels 32 is different. Generally, the filtration effect is distinguished according to the mesh size, so filter cartridges 34 with different filtration capabilities can be used for different plastic particles.

[0049] The metering pump 4 is used for flow regulation of liquid plastic, and it adopts the metering pump 4 commonly used in the prior art.

[0050] One end of the metering pump 4 is connected to the housing 30, and the other end is connected to the forming frame 5. The forming frame 5 is provided with a forming port 50. Both ends of the forming port 50 are provided with sliding adjustment blocks 51 and driving components for moving the sliding adjustment blocks 51. The length of the forming port 50 can be limited by the two sliding adjustment blocks 51, so that sheets of different widths can be output from the forming port 50.

[0051] Since the sheet output from the forming port 50 cannot guarantee a consistent thickness, a shaping device 6 is also required to shape the sheet and ensure its consistent thickness.

[0052] like Figures 6 to 8 As shown, the shaping device 6 includes a shaping frame 60, on which a first cooling roller 61, a second cooling roller 62, a third cooling roller 63, a conveying roller 64, and a drive assembly 65 for driving each roller to rotate are provided. Each cooling roller has a bearing seat 68 at both ends. The drive assembly 65 is mounted on the bearing seat to drive the corresponding cooling roller to rotate. The first cooling roller 61, the second cooling roller 62, and the third cooling roller 63 are each provided with a cooling channel along their respective axial direction. Each cooling channel is connected and externally connected to a cooling device. Coolant is circulated into each cooling channel through the cooling device.

[0053] The sheet material output from the forming port 50 is first extruded and shaped by the first cooling roller 61 and the second cooling roller 62, then extruded and shaped by the second cooling roller 62 and the third cooling roller 63, and then output to the conveyor frame 7 through the conveyor roller 64.

[0054] It is understandable that the structure of the cooling roller and its internal cooling channels can be based on commonly used conveyor rollers with good cooling effects.

[0055] The bottom of the forming frame 60 is provided with a slide rail structure 67, which allows it to adjust the distance between itself and the forming frame 5.

[0056] Both the first cooling roller 61 and the third cooling roller 63 are provided with a thickness adjustment mechanism 66 between themselves and the forming frame 60. The thickness adjustment mechanism 66 is used to adjust the distance between two adjacent cooling rollers. Specifically, the thickness adjustment mechanism 66 includes a guide rail 600, a sliding block 601, and a drive motor 602. Taking the first cooling roller 61 as an example, the sliding block 601 is located at the bottom of the bearing seats 68 at both ends of the first cooling roller 61, and the guide rail 600 is located on the forming frame 60. The forming frame 60 is provided with an adjustment driver for driving the bearing seats to move. The adjustment driver can be a cylinder, an electric push rod, etc. With this configuration, the sheet material is extruded and shaped to the required thickness according to user needs, and the thickness is kept uniform.

[0057] In some embodiments, the distance between the first cooling roller 61 and the second cooling roller 62, and the distance between the third cooling roller 63 and the second cooling roller 62, adjusted by the two thickness adjustment mechanisms 66, can be the same or different. If they are different, the distance between the first cooling roller 61 and the second cooling roller 62 needs to be greater than the distance between the third cooling roller 63 and the second cooling roller 62. By performing two shaping processes in a progressive manner, the shaping effect is better.

[0058] The cutting device 8 is mounted on the conveyor frame 7 and is used to cut the shaped sheet into the required width. The cutting device 8 includes a cutting frame 80, and both ends of the cutting frame 80 are provided with cutting components 81. The cutting component 81 includes an adjustment frame, a cutting blade 810 mounted on the adjustment frame, and a cutting motor that drives the cutting blade 810 to rotate. The distance between the two cutting blades 810 can be adjusted by the adjustment frame to cut the sheet into the required width. The adjustment frame can adopt a structure of cylinder combined with slider and slide rail.

[0059] Several conveying rollers are provided on both sides of the cutting device 8 on the conveying frame 7, and the sheet is conveyed above the conveying rollers.

[0060] The cutting frame 80 is provided with support roller assemblies 82 on both sides of the cutting blade 810. Each support roller assembly 82 includes an adjusting screw 820, a moving block 821, and a support roller 822. The cutting frame 80 is vertically provided with a slide groove 800. The moving block 821 slides along the slide groove 800. The support roller 822 is connected to the moving block 821. The adjusting screw 820 and the moving block 821 are threaded together. Rotating the adjusting screw 820 causes the moving block 821 to move up and down along the slide groove 800. The two support roller assemblies 82 can lift the sheet to a position that is conducive to cutting by the cutting blade 810.

[0061] The rear end of the conveyor frame 7 is provided with a traction assembly 70. The traction assembly 70 includes a traction frame 700, an upper traction roller 701, a lower traction roller 702, an adjustment assembly 703, and a traction motor. The lower traction roller 702 is rotatably disposed at the lower part of the traction frame 700, and one end is connected to the traction motor. The two ends of the traction frame 700 are vertically provided with slots above the lower traction roller 702. The adjustment assembly 703 includes a clamping cylinder and a fixed seat driven by it to slide along the slot. The upper traction roller 701 is rotatably disposed on the fixed seat.

[0062] The winding device 9 is mounted on the conveyor frame 7 and located behind the traction assembly 70. The winding device 9 includes a winding motor and a winding shaft.
