Description

Technical Field

[0001] This utility model relates to the field of sheet processing technology, specifically to a guiding device for processing modified PP polypropylene sheets. Background Technology

[0002] Modified PP polypropylene sheets are made from polypropylene as the base material. By adding toughening agents, fillers, and antioxidants, the impact resistance, high temperature resistance, and aging resistance of polypropylene sheets can be improved, making them suitable for different application scenarios. The processing of polypropylene sheets usually involves melting and plasticizing the modified PP raw material in an extruder, then extruding it into sheets through a mold. Subsequent secondary processing, such as cutting, bending, or welding, is carried out according to requirements. They are widely used in packaging, building materials, and automotive interiors.

[0003] Existing technologies often have the following problems when used: The positioning and guiding mechanisms in modified polypropylene sheet processing equipment are mostly fixed designs, usually only suitable for sheets of a single specification. They are difficult to apply to the processing of polypropylene sheets of different widths or thicknesses, resulting in poor versatility of the positioning and guiding mechanisms in the processing equipment. In addition, polypropylene is prone to jamming or slipping during the process of being transported to the processing point, which prevents the polypropylene sheet from accurately reaching the processing point and thus affects the subsequent processing quality of the polypropylene sheet. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a guiding device for processing modified PP polypropylene sheets. This device effectively solves the problems of existing positioning and guiding mechanisms being difficult to apply to processing polypropylene sheets of different widths or thicknesses, resulting in poor versatility of the positioning and guiding mechanism, and the tendency for polypropylene sheets to jam or slip during transport before processing, thus affecting the subsequent processing quality of the polypropylene sheets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a guiding device for processing modified PP polypropylene sheets, comprising: A frame, wherein a processing platform is fixedly connected to the inner side of the frame, and two support side plates are fixedly connected to the top of the frame, and multi-directional positioning components are provided on the two support side plates; The multi-directional positioning component includes limiting sliding holes formed on two support side plates. Each of the two limiting sliding holes is slidably connected to a sliding frame. Each of the two sliding frames has a short-axis electric push rod fixedly mounted on its upper end face. Each of the two short-axis electric push rods has a connecting bracket fixedly connected to its telescopic end. Each of the two connecting brackets has an abutment plate fixedly connected to its end near the processing platform. A lateral adjustment component is fixedly connected to the bottom end of the frame. The lateral adjustment component is used to adjust the distance between the two abutment plates. An auxiliary material conveying assembly is rotatably connected to the side wall of the frame.

[0006] Furthermore, the lateral adjustment component includes two fixed brackets fixedly connected to the bottom end of the frame. The lower ends of the two fixed brackets are rotatably connected to ball screws. The threads on the two ball screws are in opposite directions, and the outer peripheral walls of the two ball screws are threaded with sliders. The two sliders are respectively fixedly connected to the bottom ends of the two sliding frames.

[0007] Furthermore, the lateral adjustment component also includes a dual-axis motor fixedly installed on the lower end face of the frame, and the two output ends of the dual-axis motor are respectively fixedly connected to the ends of two ball screws through couplings.

[0008] Furthermore, the auxiliary material conveying assembly includes several rotating rods rotatably connected to the side wall of the frame, each of the rotating rods having a guide conveying roller fixedly connected to its outer peripheral wall, and each of the rotating rods having a transmission gear fixedly connected to its end. A linear electric push rod is fixedly installed on the outer wall of the frame, and a toothed plate is fixedly connected to the telescopic end of the linear electric push rod. Each of the transmission gears meshes with the toothed plate for transmission.

[0009] Furthermore, several strip-shaped silicone strips are fixedly connected to the outer peripheral wall of the guide conveyor roller.

[0010] Furthermore, the lower end of the abutment plate is configured in an inverted L-shape, and a buffer pad is fixedly connected to the outer surface of the abutment plate.

[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: This invention incorporates a multi-directional positioning component. By driving two sliding frames to move in opposite directions, the two abutment plates gradually approach the side of the polypropylene sheet. Simultaneously, the lower ends of the abutment plates are driven to move closer to the side of the polypropylene sheet, ensuring that the lower ends of the two abutment plates fully abut and fix the side of the polypropylene sheet. This allows for precise positioning and guidance of polypropylene sheets of different widths or thicknesses, effectively improving the versatility of the positioning and guidance of the polypropylene processing device.

[0012] This invention includes an auxiliary material conveying component. Several guide conveying rollers rotate counterclockwise synchronously in the same direction to help move the polypropylene sheet closer to the processing platform and prevent the polypropylene sheet from getting stuck or slipping during conveying. This ensures that the polypropylene can accurately reach the processing point and helps guarantee the subsequent processing quality of the polypropylene sheet. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] Example: Refer to Figures 1 to 3 A guide device for processing modified PP polypropylene sheets includes: a frame 1, a processing platform 2 fixedly connected to the inner side of the frame 1, and two support side plates 3 fixedly connected to the top of the frame 1, with multi-directional positioning components provided on the two support side plates 3. The multi-directional positioning component includes limiting sliding holes 4 opened on two support side plates 3. Sliding frames 5 are slidably connected to both limiting sliding holes 4. Short shaft electric push rods 6 are fixedly installed on the upper end face of both sliding frames 5. The short shaft electric push rods 6 adopt the model DT50-50-500. Connecting brackets 7 are fixedly connected to the telescopic ends of both short shaft electric push rods 6. Abutting plates 8 are fixedly connected to the ends of both connecting brackets 7 near the processing platform 2. The lower end of the abutting plate 8 is set in an inverted L-shaped structure, and a buffer pad is fixedly connected to the outer surface of the abutting plate 8. A lateral adjustment component is fixedly connected to the bottom of the frame 1. The lateral adjustment component is used to adjust the distance between the two abutment plates 8. The lateral adjustment component includes two fixed brackets 9 fixedly connected to the bottom of the frame 1. A ball screw 10 is rotatably connected to the lower end of each of the two fixed brackets 9. The threads on the two ball screws 10 are in opposite directions, and the outer peripheral walls of the two ball screws 10 are threaded with sliders 11. The two sliders 11 are fixedly connected to the bottom ends of the two sliding frames 5 respectively. The lateral adjustment component also includes a dual-axis motor 12 fixedly installed on the lower end face of the frame 1. The dual-axis motor 12 adopts the model 6SL3120-2TE15-0AD0. The two output ends of the dual-axis motor 12 are fixedly connected to the ends of the two ball screws 10 respectively through couplings. Specifically, the threads on the two ball screws 10 are in opposite directions. When driving the two ball screws 10 to rotate synchronously in the same direction, the two sliders 11 respectively rotate with the threads of the two ball screws 10 and move in opposite or opposite directions along the axial direction of the two ball screws 10. Specifically, when driving the two sliders 11 to move in opposite directions or back directions, since the sliding frame 5 slides at the limiting sliding hole 4, that is, the sliding frame 5 can slide and cooperate with the support side plate 3 through the limiting sliding hole 4, the horizontal movement of the sliding frame 5 and the slider 11 as a whole can be limited, ensuring the linearity and stability of the two abutting plates 8 moving in opposite directions. By driving the two sliding frames 5 to move in opposite directions, the two abutting plates 8 gradually approach the side of the polypropylene sheet. At the same time, the lower end of the abutting plate 8 is driven to move closer to the side of the polypropylene sheet, so that the lower end of the two abutting plates 8 can fully abut and fix the side of the polypropylene sheet. This allows for precise positioning and guidance of polypropylene sheets of different widths or thicknesses, effectively improving the versatility of the positioning and guidance of the polypropylene processing device.

[0018] An auxiliary material conveying assembly is rotatably connected to the side wall of the frame 1. The auxiliary material conveying assembly includes several rotating rods 13 rotatably connected to the side wall of the frame 1. Guide conveying rollers 14 are fixedly connected to the outer peripheral walls of the rotating rods 13. Several strip-shaped silicone strips are fixedly connected to the outer peripheral walls of the guide conveying rollers 14. Transmission gears 15 are fixedly connected to the ends of the rotating rods 13. A linear electric push rod 16 is fixedly installed on the outer wall of the frame 1. The linear electric push rod 16 adopts the model RM-SLA-08-30-1. A toothed plate 17 is fixedly connected to the telescopic end of the linear electric push rod 16. The several transmission gears 15 mesh with the toothed plate 17 for transmission. Specifically, when assisting in the conveying of subsequent polypropylene sheets, after the previous polypropylene sheet is conveyed, that is, after the corresponding polypropylene sheet has arrived on the processing platform 2, the guide conveying rollers 14 are in a freely rotatable state (no polypropylene sheet is in contact with the guide conveying rollers 14). The telescopic end of the linear electric push rod 16 is controlled to retract, thereby driving the guide conveying rollers 14 to rotate in the opposite direction and reset. After the next polypropylene sheet comes into contact with the guide conveying rollers 14, the guide conveying rollers 14 can be driven to rotate counterclockwise and move the polypropylene sheet, so as to facilitate the conveying of subsequent polypropylene sheets. Several guide conveyor rollers 14 are driven to rotate counterclockwise synchronously in the same direction. When the guide conveyor rollers 14 rotate, the strip-shaped silicone strips on their outer peripheral walls will contact the bottom surface of the polypropylene sheet. Through friction, the polypropylene sheet is moved closer to the processing platform 2 and moved stably, avoiding jamming or slippage of the polypropylene sheet during conveying. This ensures that the polypropylene can accurately reach the processing point, which is beneficial to ensuring the subsequent processing quality of the polypropylene sheet.

[0019] The working principle of this utility model is as follows: In use, the polypropylene sheet to be processed is conveyed to the processing platform 2 via the auxiliary feeding assembly. The two connecting brackets 7 are driven to move downward by controlling the two short-shaft electric push rods 6, so that the lower ends of the two abutment plates 8 are close to the parallel position of the top of the polypropylene sheet. Then, the dual-shaft motor 12 is controlled to run, and the dual-shaft motor 12 drives the two ball screws 10 to rotate, so that the two ball screws 10 move and drive the two sliding frames 5 to move in opposite directions, so that the two abutment plates 8 gradually approach the side of the polypropylene sheet. At the same time, the two short-shaft electric push rods 6 continue to run, so that the two short-shaft electric push rods 6 continue to drive the lower ends of the abutment plates 8 to move closer to the side of the polypropylene sheet, so that the lower ends of the two abutment plates 8 fully abut and fix the side of the polypropylene sheet. When the polypropylene sheet to be processed is transported to the processing platform 2 by the auxiliary feeding assembly, the polypropylene sheet can be placed above several guide conveyor rollers 14. The extension end of the linear electric push rod 16 is extended and operated. The extension end of the linear electric push rod 16 drives the toothed plate 17 to move. Several transmission gears 15 mesh with the toothed plate 17 to drive several rotating rods 13 and several guide conveyor rollers 14 to rotate counterclockwise in the same direction. When the several guide conveyor rollers 14 rotate, the strip silicone strip on their outer peripheral wall will contact the bottom surface of the polypropylene sheet. Through friction, the polypropylene sheet is moved closer to the processing platform 2 and moved stably, and finally accurately reaches the processing point above the processing platform 2.

[0020] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
