DETAILED DESCRIPTION

[0050] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0052] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0054] Example 1

[0055] Reference Figure 1 to Figure 6 , which is a rapid switching device for forming equipment for producing filter rods of multiple specifications proposed by the present invention, including a tow supply device 7, a filter paper supply device 8, a filter rod forming device 9, a filter rod cutting device 10 and a filter rod collecting device 11, the filter rod cutting device 10 includes: a chassis 1001; a knife disc 12 rotatably arranged in the chassis 1001. The knife disc 12 is used to cut the filter rod; a telescopic member 1 has a connecting end 1022 and a moving end 1033, the connecting end 1022 is located in the chassis 1001, and the moving end 1033 is located outside the chassis 1001; an adjusting plate 2, the connecting end 1022 is hinged to the middle part of the adjusting plate 2, and the adjusting plate 2 is used to adjust the deflection angle of the knife disc 12.

[0056] In the above scheme, the tow supply device 7 conveys the fiber tow to the filter rod forming device 9, and the filter paper supply device 8 provides filter paper. In the filter rod forming device 9, the tow is loosened, evenly coated with plasticizer and wound into a filter rod prototype. The formed filter rod is pushed by the filter rod feeding member 13 to the top of the cutter disc 12 located in the chassis 1001. A rotatable cutter disc 12 is installed in the chassis 1001, and a blade 14 is arranged on the circumferential side wall of the cutter disc 12. An adjustment mechanism for adjusting the deflection angle of the cutter disc 12 is arranged below the cutter disc 12. The adjustment mechanism includes a telescopic member 1 and an adjustment plate 2. The connecting end 1022 of the telescopic member 1 is located in the chassis 1001 and is hinged to the middle part of the adjustment plate 2. The adjustment plate 2 can contact the side wall of the cutter disc 12 to change the angle of the cutter disc 12. By changing the angle of the cutter disc 12, the length of the cut filter rod can be changed to meet the production of filter rods of different specifications. The movable end 1033 of the telescopic member 1 is located outside the chassis 1001 for easy operation.

[0057] Specifically, firstly, the filter rod cutting device 10 of the filter rod forming equipment significantly improves the operational safety. In the traditional filter rod cutting equipment, when it is necessary to produce filter rods of different length specifications and manually adjust the deflection angle of the cutter disc 12, the operator needs to be in close contact with the operating parts of the equipment, which poses a great safety hazard. However, the present device uses the adjustment plate 2 in the chassis 1001 and the telescopic part 1 outside the chassis 1001 to change the angle of the cutter disc 12. The operator does not need to directly touch the cutter disc 12, which effectively avoids the risk of personal injury caused by misoperation or accidental start-up of the equipment.

[0058] Secondly, the production efficiency is greatly improved. In the past, manual adjustment of the cutter disc 12 often required long downtime to ensure the accuracy of the adjustment and the safety of the operator, which would cause production interruptions and reduce overall production efficiency. The device enables the deflection angle of the cutter disc 12 to be quickly adjusted with only a short downtime during the filter rod production process, reducing production interruption time and making the production process more continuous and smooth, thereby effectively increasing the filter rod output per unit time.

[0059] Finally, it helps to ensure the stability and consistency of the filter rod cutting quality. The interaction between the adjustment plate 2 and the cutter disc 12 and the precise control of the adjustment plate 2 by the telescopic member 1 can more accurately adjust the deflection angle of the cutter disc 12, thereby ensuring that the length error of each filter rod cut is controlled within a very small range, which can effectively reduce product quality problems caused by inconsistent filter rod lengths and improve the overall product qualification rate and market competitiveness.

[0060] Reference Figure 2It should be noted that the left side of the cutter disc 12 of the present invention is a driving device, which is driven by a rotating shaft, and the right side of the cutter disc 12 is a ball joint to limit the moving direction of the cutter disc 12. Specifically, when the cutter disc 12 is unlocked, the present invention is not only applicable to the traditional method of locking the driving device with the center of the cutter disc through a locking nut. When adjusting this method, only the locking nut needs to be manually loosened. Similarly, after adjustment, only the locking nut needs to be tightened. The present invention adds a limit clamp, refer to Figure 2 The parts on the left side of the middle blade have eliminated the traditional locking nut. Figure 6 The output end of the cutter disc and the driver are hinged. When the cutter disc is working, the limit clamping claw of the drive device of the present invention slides against the outer wall of the cutter disc. When the cutter disc needs to be adjusted, the limit clamping claw can follow the cutter disc to move and adjust by gripping the cutter disc. Secondly, the limit clamping claw can also realize emergency locking brake.

[0061] Furthermore, the telescopic member 1 includes: a box body 101 is arranged on the side wall of the chassis 1001; the gear part 105 is arranged in the middle of the box body 101; the first rod body 102 is slidably arranged at one end of the box body 101, the connecting end 1022 is located on the first rod body 102, the first rod body 102 has a first rack part 1021, and the first rack part 1021 is engaged with the gear part 105 for transmission; the second rod body 103 is slidably arranged at the other end of the box body 101, the moving end 1033 is located on the second rod body 103, the second rod body 103 has a second rack part 1031, the second rack part 1031 is engaged with the gear part 105 for transmission, and after the second rod body 103 moves, the gear part 105 drives the first rod body 102 to move.

[0062] In the above scheme, the bent box body 101 is fixedly installed on the side wall of the chassis 1001, and the box body 101 is fixedly arranged vertically with the side wall of the chassis 1001. It can be understood that the box body 101 takes the bending point as the midpoint, half of the box body 101 is inside the chassis 1001, and the other half is outside the chassis 1001, which is convenient for adjustment. The bending angle is the same as the initial deflection angle of the blade 12. For example, the initial deflection angle of the blade 14 is capable of cutting a filter rod with a length of 10 mm.

[0063] Working process: When the mobile end 1033 of the second rod body 103 is pushed, the second rack part 1031 drives the semi-arc gear 1052 to rotate. Due to the meshing relationship of the gears, the semi-arc gear 1052 simultaneously drives the first rod body 102 where the first rack part 1021 is located to move. The displacement of the connecting end 1022 of the first rod body 102 is transmitted to the adjustment plate 2, so that the adjustment plate 2 rotates to change the angle of the cutter disc 12. Through a simple meshing transmission structure of the rod body and the gear part 105, the purpose of controlling the movement of the adjustment plate 2 in the chassis 1001 by operating the mobile end 1033 outside the chassis 1001 is achieved. By using the semi-arc gear 1052 in conjunction with the staggered rack part, a relatively stable and precise transmission can be achieved in a limited space, which effectively ensures the reliability and accuracy of the angle adjustment of the cutter disc 12, and helps to improve the filter rod cutting quality and the overall operation stability of the equipment.

[0064] Furthermore, the box body 101 is bent, and the box body 101 is arranged perpendicular to the side wall of the chassis 1001 . The bending angle of the box body 101 is the same as the initial deflection angle of the cutter disc 12 .

[0065] In the above solution, the box body 101 is bent, one end of the box body 101 is vertically connected to the side wall of the chassis 1001, and the bending angle matches the deflection angle of the cutter head 12 when it is initially installed.

[0066] Working process: When the angle of the cutter disc 12 is adjusted, the linear motion of the moving end 1033 of the second rod 103 is converted into a displacement of the connecting end 1022 of the first rod 102 in a suitable direction under the guidance of the bent structure of the box body 101 and the transmission of the gear part 105. The displacement acts on the cutter disc 12 through the adjustment plate 2, so that the cutter disc 12 can be deflected in a predetermined direction. During the adjustment process, the bent box body 101 can better guide the direction of force transmission, reduce unnecessary force and friction, improve transmission efficiency, and help maintain the stability and coordination of the internal structure of the equipment, so that the angle adjustment process of the cutter disc 12 is smoother and more accurate.

[0067] Furthermore, the gear portion 105 includes: a fixed shaft 1051 disposed at a bend in the middle of the box body 101; a semi-arc gear 1052 disposed on the fixed shaft 1051, and the semi-arc gear 1052 is meshed with the first rack portion 1021 and the second rack portion 1031 respectively.

[0068] In the above scheme, when the second rod body 103 moving end 1033 is pushed to move the second rack portion 1031, the semi-arc gear 1052 rotates around the fixed axis 1051, driving the first rod body 102 where the first rack portion 1021 is located to move in the opposite direction. This meshing relationship makes the transmission and conversion of force more stable during the adjustment process, and there will be no jamming or jumping. The structure of the semi-arc gear 1052 enables transmission adjustment in a larger angle range within the limited space of the box body 101 to meet the requirements of different deflection angles of the cutter disc 12. The staggered meshing cooperation with the first rack portion 1021 and the second rack portion 1031 improves the accuracy and reliability of the transmission, reduces the transmission error caused by tooth surface wear or uneven force, ensures the accuracy of the angle adjustment of the cutter disc 12, and thus improves the consistency of the filter rod cutting length.

[0069] Furthermore, the first rack portion 1021 and the second rack portion 1031 are staggered.

[0070] In the above scheme, when adjusting the angle of the cutter disc 12, the movement of the moving end 1033 of the second rod body 103 is transmitted to the semi-arc gear 1052 through the second rack portion 1031, and the semi-arc gear 1052 rotates to drive the first rack portion 1021 and the first rod body 102 to move. Due to the staggered arrangement, the first rod body 102 and the second rod body 103 do not interfere with each other during the movement, and can more stably transmit the force to the adjustment plate 2. This staggered arrangement avoids the collision and interference between the first rod body 102 and the second rod body 103 during the movement, and improves the operational reliability and stability of the telescopic member 1. At the same time, the movement of the adjustment plate 2 can be more accurately controlled, thereby improving the accuracy of the angle adjustment of the cutter disc 12, which is conducive to the production of filter rods with more accurate length specifications and reducing product quality problems caused by cutting length errors.

[0071] Furthermore, it also includes: a fixed plate 3 is arranged in the chassis 1001, and the fixed plate 3 is located below the blade disc 12; the column 4 is slidably arranged on the fixed plate 3, and the adjustment plate 2 is rotatably arranged on the column 4, and the middle part of the adjustment plate 2 has a hinged end 201, and the hinged end 201 is hinged to the first rod body 102.

[0072] In the above scheme, when the connecting end 1022 of the first rod body 102 moves, the adjusting plate 2 is pulled or pushed by the connecting rod 104 to rotate around the axle pin at the top of the column 4. Driven by the screw motor 6, the column 4 can slide along the guide rail on the fixed plate 3, so that the contact position and angle between the adjusting plate 2 and the cutter disc 12 can be adjusted, so that the adjusting plate 2 can better act on the cutter disc 12, and the precise adjustment of different positions and angles of the cutter disc 12 can be achieved. The sliding connection structure between the column 4 and the fixed plate 3 increases the adjustment flexibility of the adjusting plate 2, and can adapt to the angle adjustment requirements of different parts of the cutter disc 12. By driving the column 4 by the screw motor 6, automatic position adjustment can be achieved, which improves the intelligence level of the equipment. In addition, this structure enables the adjusting plate 2 to contact and transmit force with the cutter disc 12 more stably, ensures the accuracy and reliability of the angle adjustment of the cutter disc 12, and is conducive to improving the cutting quality and production efficiency of the filter rod.

[0073] Furthermore, it also includes: a suction cup 5 is arranged on the side of the adjustment plate 2 away from the hinge end 201, there are a plurality of suction cups 5, and the plurality of suction cups 5 are respectively arranged at the two ends of the adjustment plate 2, and the suction cups 5 are used to abut against the side wall of the cutter disc 12.

[0074] In the above scheme, suction cups 5 are respectively installed at both ends of the side of the adjustment plate 2 away from the hinge end 201 of the adjustment plate 2 and the first rod body 102. The suction cups 5 are electromagnetic suction cups. When the adjustment plate 2 rotates and approaches the cutter disc 12, the suction cups 5 contact the side walls of the cutter disc 12. During the angle adjustment process of the cutter disc 12, the adjustment plate 2 rotates to make the suction cups 5 abut against the side walls of the cutter disc 12. Due to the adsorption effect of the suction cups 5, they can be quickly adsorbed on the side of the cutter disc 12, and when adjusting the angle of the cutter disc 12, the cutter disc 12 can be pushed to rotate more stably, thereby improving the adjustment accuracy. The provision of the suction cups 5 enhances the control ability of the adjustment plate 2 over the cutter disc 12, effectively reduces the shaking and displacement of the cutter disc 12 during the adjustment process, and improves the stability of the operation of the cutter disc 12.

[0075] Furthermore, it also includes: one end of the connecting rod 104 is hinged on the connecting end 1022, and the other end is hinged on the hinge end 201; the screw motor 6 is arranged on the fixed plate 3, and the column 4 is arranged on the screw motor 6, and the screw motor 6 is used to drive the column 4 to slide along the fixed plate 3.

[0076] In the above solution, the function of the connecting rod 104 is to cooperate with the movement of the column 4 on the fixed plate 3 to ensure that the suction cup 5 can be away from the cutter disc 12 when not adjusted.

[0077] Furthermore, the second rod body 103 has a scale mark 1032 , and the end surface of the box body 101 close to the second rod body 103 is a measuring surface.

[0078] In the above scheme, when the operator adjusts the angle of the cutter disc 12 to change the cutting length of the filter rod, he first determines the corresponding scale position according to the production process requirements, and then pushes the movable end 1033 of the second rod body 103 to move it to the specified scale position. At this time, through the internal transmission of the telescopic member 1, the connecting end 1022 of the first rod body 102 produces a corresponding displacement, driving the adjustment plate 2 to adjust the angle of the cutter disc 12. The setting of the scale mark 1032 provides an intuitive quantitative basis for adjusting the angle of the cutter disc 12. The operator can quickly and accurately move the second rod body 103 to the desired position, reducing the trial and error and adjustment time during the adjustment process. It improves the convenience of operation and production efficiency of the equipment, and also helps to ensure the consistency and accuracy of the filter rod cutting length, thereby improving product quality.

[0079] Furthermore, it also includes: a filter rod feeder 13 is arranged in the chassis 1001 and located above the cutter disc 12, and the filter rod feeder 13 is used to transport the formed filter rod to the cutting position; a blade 14 is arranged on the circumferential side wall of the cutter disc 12, and the blade 14 is used to cut the filter rod after the cutter disc 12 rotates; a sharpener 15 is arranged on one side of the cutter disc 12, and the sharpener 15 is used to grind the blade 14.

[0080] In the above scheme, the filter rod feeder 13 is installed in the chassis 1001 and is located above the cutter disc 12, and stably transports the formed filter rod to the cutting position above the cutter disc 12. The blade 14 is fixed to the circumferential side wall of the cutter disc 12 by welding or other means, and the sharpener 15 is installed on one side of the cutter disc 12, and adopts an electric or pneumatic driving method to make the whetstone contact with the blade 14 for grinding.

[0081] Working process: The formed filter rod moves to the top of the cutter disc 12 at a uniform speed under the action of the filter rod feeder 13. The cutter disc 12 rotates at a high speed, and the blade 14 cuts the filter rod into the required length. During the cutting process or when the equipment is shut down, the sharpener 15 starts to grind the blade 14 to maintain the sharpness of the blade 14. The filter rod feeder 13 can stably and accurately transport the filter rod to the cutting position, ensuring the accuracy and continuity of the cutting. The sharp blade 14 helps to improve the quality of the cut surface of the filter rod and reduce burrs and deformation. The setting of the sharpener 15 extends the service life of the blade 14, reduces the reduction in cutting quality due to wear of the blade 14 and the frequency of equipment shutdown to replace the blade 14, and improves the overall operating efficiency and production stability of the equipment.

[0082] Example 2

[0083] like Figure 7 As shown, a rapid adjustment method for filter rod forming equipment proposed by the present invention is applied to the rapid switching device for forming equipment for producing filter rods of multiple specifications in Example 1, specifically, comprising the following steps:

[0084] Step 1: Determine the desired deflection angle of the cutter head 12;

[0085] Step 2: The screw motor 6 drives the column 4 to move toward the cutter disc 12, and the suction cup 5 is adsorbed on the side wall of the cutter disc 12;

[0086] Step 3: The cutter head 12 and the output shaft of the driving device are unlocked;

[0087] Step 4: Move the second rod 103 outside the chassis 1001 to the desired scale, the second rod 103 drives the semi-arc gear 1052 to deflect, the semi-arc gear 1052 drives the first rod 102 to move linearly, the first rod 102 drives the adjustment plate 2 to deflect along the column 4, and the suction cup 5 drives the cutter disc 12 to deflect to the desired position;

[0088] Step 5: The cutter head 12 is locked with the driving device again;

[0089] Step 6: The screw motor 6 drives the column 4 to move away from the cutter disc 12, the suction cup 5 is disengaged from the cutter disc 12, and the angle adjustment of the cutter disc 12 is completed.

[0090] Specifically, it should be noted that the detailed working process of the filter rod forming device is as follows:

[0091] When the filter rod forming equipment is working, the rolled tow first enters the opening process, and the tight tow fibers are disassembled through mechanical tearing and fine combing to make them loose and uniform; then, the conveying mechanism strictly controls the conveying speed and tension of the tow, so that it moves forward to the next stage continuously, evenly and regularly, and prevents the accumulation and breakage of the tow, which interferes with the forming quality.

[0092] When the tow reaches the application stage, the plasticizer or curing agent prepared according to the performance requirements of the filter rod is finely sprayed through the spray nozzle, or the tow is immersed in the solution tank to complete the impregnation. The precise metering pump and the regulating valve work together to firmly lock the dosage of the agent, so that the tow absorbs evenly and appropriately, fully meeting the subsequent processing requirements.

[0093] Then, the appropriate glue is selected based on the filter rod material and usage scenario. When the coating roller is gluing, it rotates at a constant speed and steadily lays a thin and uniform layer of glue on the surface of the tow; in the spray gluing mode, the atomizing nozzle turns the glue into fine droplets, which penetrate the interior of the tow in all directions. The operator flexibly adjusts the coating roller speed, the contact pressure of the rubber roller, the spray volume and other parameters to achieve precise control of the amount of glue applied.

[0094] The glued tow moves forward to the forming die, where it is extruded and constrained, gradually outlining the prototype of the filter rod. Some devices also use heat sources such as steam, hot air or infrared rays to focus on the forming die and precisely heat the tow, helping the glue to solidify quickly, accelerating the filter rod forming process and stabilizing the filter rod structure.

[0095] The formed filter rods are continuous and long strips are formed. The cutter disc in the cutting device carries a high-speed rotating tool, which rotates and cuts according to the established feed speed and cutting angle, and accurately cuts the continuous filter rods into the specified length. Relying on advanced cutting control algorithms and fine-tuned equipment parameters, it is fully guaranteed that the length of each filter rod is accurate, and the incision is flat and smooth without burrs.

[0096] After cutting is completed, the filter rod collecting device can transport and collect the segmented filter rods, which is convenient for the production process.
