Description

Technical Field

[0001] This invention belongs to the field of wire drawing machine technology, and specifically relates to a film slitting blade holder mechanism for a wire drawing machine. Background Technology

[0002] The wire drawing machine uses polypropylene and high-density ethylene as raw materials. After heating, extrusion, slitting, and stretching, flat filaments are formed and then wound up for circular loom weaving. Wire drawing machines have generally undergone multiple improvements and can use recycled materials, powders, or granules to draw flat filaments. A plastic extruder is used to first form a film of a certain width through the action of the die head. Then, as needed, the film is cut into the required width using a slitting tool device, and then used after heating and stretching.

[0003] The existing film slitting blade holder mechanism of the wire drawing machine has the same contact point between the blade and the slitting material. Therefore, it is necessary to frequently adjust the position of the blade holder manually so that the blade can slit the film at several positions within the usage length range. However, the utilization rate of the blade still needs to be improved, and impurities may adhere to the blade after long-term use, resulting in poor subsequent slitting effect or blockage of the structure.

[0004] Based on the above-mentioned situation, we found that the existing film slitting blade holder structure of wire drawing machine is difficult to avoid the above problems at the same time. Therefore, we propose a film slitting blade holder mechanism for wire drawing machine that can improve the utilization rate of the blade and facilitate the cleaning of the structure. Summary of the Invention

[0005] The purpose of this invention is to address an existing film slitting blade holder mechanism for a wire drawing machine, which has the advantages of improving blade utilization and facilitating cleaning of the structure.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a film slitting knife holder mechanism for a wire drawing machine, including a main frame, a base frame provided on the rear side of the main frame, a transmission component provided on the right side of the main frame, an inner frame rotatably connected to the inner side of the main frame, a knife holder movably connected to the bottom of the inner frame, and a knife movably connected to the inner side of the knife holder;

[0007] The transmission assembly includes a geared motor, which is bolted to the right side of the main frame. A cam is bolted to the output end of the geared motor. A connecting rod is rotatably connected to the left side of the cam. A rotating shaft is rotatably connected to the bottom of the connecting rod. A pusher is bolted to the bottom of the rotating shaft. The bottom of the pusher is bolted to the inner frame.

[0008] A cutting board is movably connected to the top of the base frame. The top of the cutting board is used in conjunction with a knife. A structural groove is formed on the inner side of the cutting board. A cleaning pad is slidably connected to the inner side of the structural groove. The outer side of the cleaning pad is slidably connected to the cutting board. A branch pipe is installed on the inner side of the cutting board. A nozzle is installed at the top of the branch pipe. A suction pump is installed at the bottom of the base frame. The drain end of the suction pump is connected to the nozzle. A contact wheel is rotatably connected to the front side of the inner side of the cutting board. A matching rod is bolted to the rear side of the cutting board. The bottom of the matching rod is movably connected to the base frame.

[0009] By adopting the above technical solution, the main frame and base frame are set up to facilitate the installation of the structure. The geared motor drives the cam to rotate, and the cam drives the push frame and the inner frame connected to it to swing back and forth inside the main frame through the connecting rod and the rotating shaft. Under the drive of the geared motor, the inner frame and the structure connected to it swing inside the main frame. All positions within the working length range of the blade can be used evenly, increasing the blade's working time, improving cutting efficiency, reducing the number of times the machine stops to replace the blade, and achieving the effect of increasing production and reducing costs. The structural groove set inside the cutting board provides space for the structure installation. At the same time, during the slitting operation, the blade inevitably produces some waste and other impurities, which can fall inside the cutting board. After the operation, the cleaning plate can be slid along the inside of the structural groove as needed to scrape the impurities along the inside of the cutting board for easy discharge. The set extraction pump can easily extract cleaning fluid from the external environment and spray the cleaning fluid onto the blade surface in contact with it through branch pipes and nozzles to achieve a cleaning effect.

[0010] The present invention is further configured such that: a crossbeam is bolted to both the front and rear sides of the main frame, a limiting roller is rotatably connected to the inner side of the crossbeam, and a pressure roller is provided on the top of the front limiting roller.

[0011] By adopting the above technical solution, the material to be cut can be conveniently limited by setting a cross frame and a limiting roller, and the pressure roller is used to flatten the material before cutting.

[0012] The present invention is further configured such that: a transverse groove is provided on the inner side of the inner frame, and the inner side of the transverse groove is slidably connected to the tool holder.

[0013] By adopting the above technical solution, when the position of the tool needs to be moved, the tool holder can be moved horizontally inside the inner frame along the horizontal groove.

[0014] The present invention is further configured such that: a back rod is bolted to the rear side of the knife holder, and the front side of the back rod is bolted to the cutting board.

[0015] By adopting the above technical solution and setting a back bar, it is easy to connect the knife holder and the cutting board. When the knife holder needs to be moved, the cutting board can be moved together, so that the movement of the structure is synchronized.

[0016] The present invention is further configured such that: a limiting strip is bolted to the top of the inner frame, and the inner side of the limiting strip is slidably connected to the tool holder.

[0017] By adopting the above technical solution and setting a limit bar, the tool holder can be easily limited when it moves, thus preventing the structure from tilting or other issues.

[0018] The present invention is further configured such that: the inner side of the tool holder is threaded with a mounting screw, and the inner side of the mounting screw is movably connected to the tool.

[0019] By adopting the above technical solution, the tool holder and the tool can be easily connected or disassembled by setting the mounting screw. Alternatively, the tool can be easily removed for replacement by removing the mounting screw.

[0020] The present invention is further configured such that: a pressure plate is bolted to the rear side of the top of the inner frame, and a fastening screw is threaded to the inner side of the knife holder, and the rear side of the fastening screw is movably connected to the pressure plate.

[0021] By adopting the above technical solution, and by setting a pressure plate in conjunction with a fastening screw, the tool holder can be pressed against the front side of the pressure plate, preventing it from shifting during operation and thus fixing the position of the structure.

[0022] The present invention is further configured such that: an inclined block is bolted to the front side of the inner side of the cutting board, and the bottom of the inclined block is slidably connected to the cleaning sheet.

[0023] By adopting the above technical solution, the inclined block can be set to limit the cleaning plate so that it can slide. When the cleaning plate passes the inclined block, it can be easy to scrape off and guide the impurities on its surface.

[0024] The present invention is further configured such that: a tension spring is bolted to the front side of the cutting board, the tension spring is disposed on the outside of the cleaning sheet, and the front side of the tension spring is bolted to the front protrusion of the cleaning sheet.

[0025] By adopting the above technical solution and setting a tension spring, the cleaning plate can be easily installed, and the spring can store force when the cleaning plate is pulled, so that it can remain in its original position when the cleaning plate is not pulled.

[0026] The present invention is further configured such that: a sub-frame is bolted to the top of the cross frame, an adjusting screw is threaded to the inner side of the sub-frame, a roller frame is rotatably connected to the bottom of the adjusting screw, and the inner side of the roller frame is rotatably connected to the pressure roller.

[0027] By adopting the above technical solution and setting up a sub-frame, it is easy to move the roller frame vertically in conjunction with the adjusting screw, so as to control the vertical drop or rise of the connected pressure roller.

[0028] In summary, the present invention has the following beneficial effects:

[0029] By setting up a main frame and base frame, the structure can be easily installed. The geared motor drives the cam to rotate, and the cam drives the push frame and the inner frame connected to it to swing back and forth inside the main frame through the connecting rod and the rotating shaft. Driven by the geared motor, the inner frame and the structure connected to it swing inside the main frame. All positions within the working length range of the blade can be used evenly, increasing the blade's working time, improving cutting efficiency, reducing the number of times the machine stops to change blades, and achieving the effect of increasing production and reducing costs. The structural groove on the inner side of the cutting board provides space for the structure installation. At the same time, during the slitting operation, the blades inevitably produce some waste and impurities, which can fall on the inner side of the cutting board. After the operation, the cleaning blade can be slid along the inner side of the structural groove as needed to scrape away the impurities along the inner side of the cutting board for easy removal. The pump can easily draw cleaning fluid from the external environment and spray the cleaning fluid onto the blade surface in contact with it through branch pipes and nozzles for a cleaning effect.

The push frame 305 and the inner frame 4 connected thereto are driven by the connecting rod 303 and the rotating shaft 304 to swing back and forth inside the main frame 1. The knife holder 5 is driven by the reduction motor 301, and the inner frame 4 and the structure connected thereto swing inside the main frame 1.

The structural groove 14 located inside the cutting board 7 provides space for structural installation.

[0042] like Figure 1 As shown, a crossbeam 20 is bolted to both the front and rear sides of the main frame 1. A limit roller 21 is rotatably connected to the inner side of the crossbeam 20. A pressure roller 22 is provided on the top of the front limit roller 21. By setting the crossbeam 20 in conjunction with the limit roller 21, it is convenient to limit the material that needs to be cut. The pressure roller 22 is used to flatten the material before cutting.

[0043] like Figure 3 As shown, a transverse groove 8 is provided on the inner side of the inner frame 4. The inner side of the transverse groove 8 is slidably connected to the tool holder 5.

[0049] Brief description of the usage process: When in use, the main frame 1 and the base frame 2 can be used to install the structure in the working position. The geared motor 301 can drive the cam 302 to rotate. The cam 302 drives the push frame 305 and the inner frame 4 connected to it to swing back and forth inside the main frame 1 through the connecting rod 303 and the rotating shaft 304. Under the drive of the geared motor 301, the inner frame 4 and the structure connected to it swing inside the main frame 1 to cut the material. At the same time, the cutting position of the cutter 6 is constantly changed. All positions of the cutter 6 within the working length range can be used evenly. As needed, the cutter 5 can also be moved along the transverse groove 8 to move the position of the cutter 6. The cutter 5 can be fixed along the pressure plate 12 by the fastening screw 13.

[0050] Example 2:

[0051] refer to Figure 1-7 A film slitting blade holder mechanism for a wire drawing machine includes a cutting board 7 movably connected to the top of a base frame 2. The top of the cutting board 7 cooperates with a blade 6. A structural groove 14 is formed on the inner side of the cutting board 7, and a cleaning sheet 15 is slidably connected to the inner side of the structural groove 14. The outer side of the cleaning sheet 15 is slidably connected to the cutting board 7.

The bottom of the matching rod 28 is movably connected to the base frame 2. When the cutting action is performed, the blade 6 will generate waste residue and other impurities, which can fall on the inner side of the cutting board 7. After the operation, the cleaning plate 15 can also be slid along the inner side of the structural groove 14 as needed, so that it can scrape the impurities along the inner side of the cutting board 7 to facilitate the discharge of the impurities. The extraction pump 18 can easily extract the cleaning liquid from the external environment, and spray the cleaning liquid onto the surface of the blade 6 in contact with it through the branch pipe 16 and the nozzle 17 to achieve the cleaning effect.

[0052] like Figure 7 As shown, an inclined block 23 is bolted to the front side of the inner side of the cutting board 7. The bottom of the inclined block 23 is slidably connected to the cleaning sheet 15. By setting the inclined block 23, the cleaning sheet 15 can be limited so that it can slide.

[0054] Brief description of the usage process: After the operation, the cleaning plate 15 is slid along the inner side of the structural groove 14 as needed. At this time, the tension spring 24 is charged, and the cleaning plate 15 scrapes the impurities along the inner side of the cutting board 7. The cleaning plate 15 moves along the inclined block 23, and when it passes the inclined block 23, the impurities are scraped off so that they can be discharged. The pump 18 can easily draw the cleaning liquid from the external environment, and spray the cleaning liquid onto the surface of the knife 6 in contact with it through the branch pipe 16 and the nozzle 17 to spray and clean it.
