Description

Technical Field

[0001] This utility model relates to the field of filter paper processing and production technology, and in particular to a filter paper slitting machine. Background Technology

[0002] Filter paper is typically made of cotton fibers and is manufactured using different methods depending on its intended use. Because it is a fibrous material, its surface has countless tiny pores that allow liquid particles to pass through, while larger solid particles cannot. This property allows for the separation of mixed liquid and solid substances.

[0003] Filter paper needs to be slit using a slitting machine during production and processing. A slitting machine is a mechanical device that cuts wide-width paper, mica tape, or film into multiple narrow strips of material. It is commonly used in papermaking machinery, wire and cable mica tape, and printing and packaging machinery. Slitting machines are mainly used for slitting non-woven fabrics, mica tape, paper, insulating materials, and various film materials. They are particularly suitable for slitting narrow strips (non-woven fabrics, paper, insulating materials, mica tape, and film, etc.).

[0004] Traditional slitting machines can usually only cut filter paper of a certain width, which is not very adaptable. If filter paper of different widths needs to be cut, the cutting blades need to be changed frequently. However, changing the cutting blades of a slitting machine is quite troublesome, as it requires disassembling the surrounding parts of the cutting blade, which is time-consuming and laborious, prolonging the downtime of the slitting machine and hindering the increase in output. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a filter paper slitting machine. The specific technical solution is as follows: A filter paper slitting machine includes a slitting machine body, a feeding mechanism installed at the feeding end of the slitting machine body for conveying filter paper, a slitting mechanism installed inside the slitting machine body for slitting the filter paper, a waste collection box slidably disposed at the bottom of the inner side of the slitting machine body for collecting the scrap material generated after slitting the filter paper, and a control mechanism installed on the outer side of the slitting machine body. The slitting mechanism includes a support plate rotatably disposed in the middle of the inner side of the slitting machine body for supporting the filter paper, multiple hydraulic cylinders fixedly installed at the top of the inner side of the slitting machine body, and multiple slitting blades disposed at the bottom of the hydraulic cylinders for slitting the filter paper on the support plate.

[0006] The slitting blade includes a mounting plate fixedly mounted on the bottom of the hydraulic cylinder and several precision blades fixedly mounted on the bottom of the mounting plate. The precision blades of the multiple sets of slitting blades are staggered. An inclined electric push rod is rotatably provided between one side of the inner wall of the slitting machine body and the bottom of the support plate.

[0007] By adopting the above technical solution, multiple hydraulic cylinders can extend and retract to drive multiple component cutters to lift and lower accordingly, thereby cutting the filter paper. Furthermore, due to the staggered arrangement of the precision blades among the multiple component cutters, the operator can adjust the spacing of the precision blades during cutting by extending and retracting the corresponding hydraulic cylinders to adapt to the cutting of filter paper of different widths, thus exhibiting strong adaptability.

[0008] Optionally, the feeding mechanism includes a drive wheel and a driven wheel rotatably mounted on the feeding end of the slitting machine body for conveying filter paper. A motor for driving the drive wheel to rotate is fixedly installed on the feeding end of the slitting machine body. Two meshing gears are fixedly provided on the outer wall of one end of the drive wheel and the driven wheel.

[0009] By adopting the above technical solution, the motor will drive the drive wheel to rotate after it runs. After the drive wheel rotates, it will drive the driven wheel to rotate through two meshing gears. The rotated drive wheel and driven wheel can smoothly feed the filter paper into the slitting machine body for slitting, thereby improving the stability of the filter paper during slitting.

[0010] Optionally, the waste collection box is located directly below the support plate, and the width of the waste collection box is greater than the width of the support plate. The control mechanism includes a PLC control cabinet fixed on the outer wall of the slitting machine body for controlling the motor, hydraulic cylinder and electric push rod.

[0011] By adopting the above technical solution, the control mechanism can automatically control the slitting machine, which is convenient and practical.

[0012] Optionally, a fixed plate is fixed on one side of the inner wall of the slitting machine, located above the waste collection box. A corrugated pipe is fixed between the top of the fixed plate and the bottom of the bearing plate. An air guide pipe is fixed inside the fixed plate to discharge some air from the corrugated pipe and blow off the residual paper pieces on the top of the bearing plate when the electric push rod is shortened.

[0013] By adopting the above technical solution, the electric push rod can be extended and retracted to drive the bearing plate to rotate. When the bearing plate is tilted, the paper scraps generated after the top part is cut can be poured into the waste collection box. When the bearing plate rotates and compresses the corrugated pipe, some air inside the corrugated pipe will be discharged through the air guide pipe to form wind. The wind can blow the paper scraps remaining on the top of the bearing plate into the waste collection box, thereby improving the cleaning effect of the bearing plate.

[0014] Optionally, the fixing plate has a cleaning hole for cleaning the inside of the bellows, and a plug is threaded inside the cleaning hole of the fixing plate, and a handle is fixedly provided in the middle of the bottom surface of the plug.

[0015] By adopting the above technical solution, staff can remove the blocking plate and clean and maintain the inside of the corrugated pipe through the cleaning hole. The cleaned paper scraps can be directly discharged into the waste collection bin.

[0016] In summary, this utility model has at least one of the following beneficial effects:

[0017] 1. By extending and retracting multiple hydraulic cylinders, the multi-component cutting blades can be raised and lowered accordingly to cut the filter paper. Due to the staggered design of the precision blades among the multi-component cutting blades, the operator can adjust the spacing of the precision blades during cutting by extending and retracting the corresponding hydraulic cylinders to adapt to the cutting of filter paper of different widths. It has strong adaptability. The control mechanism can automatically control the slitting machine, which is convenient and practical.

[0018] 2. The electric push rod extends and retracts, causing the support plate to rotate. When the support plate is tilted, the paper scraps produced after the top is cut can be poured into the waste collection box. When the support plate rotates and compresses the corrugated pipe, some air inside the corrugated pipe will be discharged through the air duct, creating wind. The wind can blow the paper scraps remaining on the top of the support plate into the waste collection box, thereby improving the cleaning effect of the support plate. In addition, the staff can remove the blocking plate later and clean and maintain the inside of the corrugated pipe through the cleaning hole. The cleaned paper scraps can be directly discharged into the waste collection box, which is convenient for operation. Attached Figure Description

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0026] This utility model discloses a filter paper slitting machine, referring to... Figure 1-2 The slitting machine includes a slitting machine body 1, a feeding mechanism, a slitting mechanism, a waste collection box 4, and a control mechanism. The slitting machine body 1 can support the feeding mechanism and other components. The feeding mechanism is installed at the feeding end of the slitting machine body 1 and is used to transport wide-width filter paper into the slitting machine body 1. The discharge end of the slitting machine body 1 can be equipped with components such as traction rollers that can pull and transport the slitting filter paper. The traction rollers and other conveying components are common structures of existing slitting machines and belong to the disclosed technology, so they will not be described in detail here.

[0027] Reference Figure 1-3 The feeding mechanism includes a drive wheel 2 and a driven wheel 21 rotatably mounted at the feeding end of the slitting machine body 1 for conveying filter paper. A motor 22 for driving the drive wheel 2 to rotate is fixedly installed at the feeding end of the slitting machine body 1. Two meshing gears 23 are fixedly provided on the outer wall of one end of the drive wheel 2 and the driven wheel 21. After the motor 22 runs, it will drive the drive wheel 2 to rotate. After the drive wheel 2 rotates, it will drive the driven wheel 21 to rotate through the two meshing gears 23. The rotated drive wheel 2 and driven wheel 21 can smoothly feed the filter paper into the slitting machine body 1 for slitting, improving the stability of filter paper slitting.

[0028] Reference Figure 2 and Figure 4 The slitting mechanism includes a support plate 3 rotatably mounted in the middle of the inner side of the slitting machine body 1, the support plate 3 being used to support filter paper, multiple hydraulic cylinders 31 fixedly mounted on the top of the inner side of the slitting machine body 1, and a multi-group slitting blade located at the bottom of the hydraulic cylinders 31 for slitting the filter paper on the support plate 3. The slitting blade includes a mounting plate 32 fixedly mounted at the bottom of the hydraulic cylinder 31, and a number of precision blades 33 fixedly mounted at the bottom of the mounting plate 32. The precision blades 33 of the multi-group slitting blades are staggered. An inclined electric push rod 34 is rotatably provided between one side of the inner wall of the slitting machine body 1 and the bottom of the support plate 3. The hydraulic cylinder 31 can be a servo hydraulic cylinder driven by an existing servo motor. The mounting plate 32 can connect the precision blades 33 to the hydraulic cylinder 31.

[0029] The support plate 3 can support the filter paper during slitting, and the electric push rod 34 can support the support plate 3. One end of the support plate 3 is fitted against the inner middle of the slitting machine body 1, thereby ensuring the stability of the support plate 3 and the filter paper during slitting. Combined with the slitting of the precision blade 33, the slitting accuracy can be improved.

[0030] Reference Figure 2 and Figure 4The hydraulic cylinder 31 can extend and retract to drive the mounting plate 32 and precision blade 33 to rise and fall. After the precision blade 33 descends, it can cut the filter paper on the bottom support plate 3, cutting the wide filter paper into narrow filter paper. By controlling the extension and retraction of the corresponding hydraulic cylinder 31, some groups of slitting blades move upward and others move downward. With the staggered setting between the precision blades 33, the spacing of the precision blades 33 in each group of slitting blades can be changed after they move downward to adapt to the cutting of filter paper of different widths, which has strong adaptability.

[0031] Reference Figure 1-2 The waste collection box 4 is slidably installed at the bottom of the inner side of the matching slitting machine body 1. The waste collection box 4 is used to collect the scraps generated after slitting the filter paper. The waste collection box 4 is located directly below the support plate 3. The width of the waste collection box 4 is greater than the width of the support plate 3, so that the scraps of the filter paper after slitting can fall from the narrower support plate 3 to the wider waste collection box 4 at the bottom, which facilitates the centralized collection of waste. A door is provided on one side of the slitting machine body 1, which makes it convenient for staff to open the door to take out the waste in the waste collection box 4 and to carry out inspection and maintenance of the slitting machine body 1.

[0032] Reference Figure 1-2 The control mechanism includes a PLC control cabinet 11 fixedly mounted on the outer wall of the slitting machine body 1 for controlling the motor 22, hydraulic cylinder 31 and electric push rod 34. The PLC control cabinet 11 is an existing LC control cabinet with a built-in touch screen interface, which can support parameter setting, fault diagnosis and other functions. It is a public technology. The motor 22, hydraulic cylinder 31, electric push rod 34 and PLC control cabinet 11 are all common existing equipment. Their internal principles and circuit connections have been disclosed and will not be elaborated here. The slitting machine can be automatically controlled through the programming inside the PLC control cabinet 11.

[0033] Reference Figure 2 and Figure 5 A fixed plate 5 is fixed on one side of the inner wall of the slitting machine body 1, located above the waste collection box 4. A corrugated pipe 51 is fixed between the top of the fixed plate 5 and the bottom of the bearing plate 3. An air guide pipe 52 is fixed inside the fixed plate 5 to expel some air from the corrugated pipe 51 and blow off the residual paper pieces on the top of the bearing plate 3 when the electric push rod 34 is shortened. The fixed plate 5 can support the corrugated pipe 51. After the electric push rod 34 extends and retracts, it will drive the bearing plate 3 to rotate. After the bearing plate 3 rotates, it will stretch or compress the corrugated pipe 51. After the corrugated pipe 51 is compressed, some air inside will be discharged through the air guide pipe 52 to form wind. The wind can blow the paper pieces remaining on the top of the bearing plate 3 into the waste collection box 4, thereby improving the cleaning effect of the bearing plate 3.

[0034] Reference Figure 2 and Figure 5The fixed plate 5 has a cleaning hole for cleaning the inside of the corrugated pipe 51. The cleaning hole of the fixed plate 5 has a threaded plug plate 53. The bottom center of the plug plate 53 has a handle 54 fixedly installed. When the corrugated pipe 51 is stretched, it will suck the shredded paper from the outside into the corrugated pipe 51 through the air guide pipe 52. The staff can periodically remove the plug plate 53 and clean and maintain the inside of the corrugated pipe 51 through the cleaning hole. The cleaned shredded paper can be directly discharged into the waste collection box 4 below, which is convenient to operate. The staff can rotate the plug plate 53 through the handle 54.

[0035] The implementation principle of a filter paper slitting machine according to an embodiment of this utility model is as follows:

[0036] When in use, the control system will turn on the motor 22. After the motor 22 runs, it will drive the drive wheel 2 to rotate. After the drive wheel 2 rotates, it will drive the driven wheel 21 to rotate through two meshing gears 23. The rotated drive wheel 2 and driven wheel 21 can smoothly feed the filter paper into the slitting machine body 1 for slitting.

[0037] Next, the control mechanism controls the extension and retraction of the hydraulic cylinder 31. After the hydraulic cylinder 31 extends and retracts, it can drive the mounting plate 32 and the precision blade 33 to rise and fall. After the precision blade 33 descends, it can cut the filter paper on the bottom support plate 3, cutting the wide filter paper into narrow filter paper. By controlling the extension and retraction of the corresponding hydraulic cylinder 31, some groups of slitting blades move upward and others move downward. With the staggered setting between the precision blades 33, the spacing of the precision blades 33 in each group of slitting blades can be changed after they move downward to adapt to the cutting of filter paper of different widths. It has strong adaptability. Then, the narrow filter paper after slitting is pulled out of the slitting machine by the external traction equipment.

[0038] When the support plate 3 needs to be cleaned, the control mechanism will control the electric push rod 34 to extend and retract. After the electric push rod 34 extends and retracts, it will drive the support plate 3 to rotate. When the support plate 3 is tilted, the paper pieces generated after the top is cut can be poured into the waste collection box 4. After the support plate 3 rotates, it will stretch or compress the corrugated pipe 51. After the corrugated pipe 51 is compressed, some of the air inside will be discharged through the air guide pipe 52 to form wind. The wind can blow the paper pieces remaining on the top of the support plate 3 into the waste collection box 4, thereby improving the cleaning effect of the support plate 3.
