Description

Technical Field

[0001] This invention relates to the field of tobacco product processing technology, and in particular to a calibration device and calibration method for paper cutting rollers of cigarette machines. Background Technology

[0002] The ZJ119 cigarette machine's paper cutting wheel assembly is driven by a servo motor. When the cutter roller is being aligned and the fastening screws are tightened, the paper cutting wheel and the cutter roller move in opposite directions due to the torque, making it impossible to effectively lock the paper cutting wheel. This poses a safety threat to maintenance personnel and is prone to misalignment, damage, and other issues with the paper cutting wheel and the cutter roller. Furthermore, there is a lack of dedicated auxiliary disassembly and assembly tools.

[0003] The current method involves two operators performing maintenance simultaneously. One operator holds the handle of the paper cutting roller while the other performs calibration and maintenance. However, since manual gripping cannot be maintained for a long time, problems such as misalignment, damage, and safety hazards may still occur during maintenance, making maintenance difficult. Furthermore, the above method is time-consuming and labor-intensive. It takes about one hour to disassemble and repair the paper cutting roller and blade roller of a cigarette machine, causing the equipment to be shut down for a long time and seriously affecting production efficiency.

[0004] In view of the above reasons, the present invention provides a calibration device and calibration method for a paper cutting wheel of a cigarette machine, which can lock the paper cutting wheel during disassembly, installation, maintenance and repair of the paper cutting wheel and its mating parts, so as to facilitate calibration. Summary of the Invention

[0005] The purpose of this invention is to provide a calibration device and method for the paper cutting roller of a cigarette machine, which can effectively lock the paper cutting roller when the cutter roller is being calibrated and tightened, thereby avoiding threats to the safety of maintenance personnel and improving maintenance efficiency.

[0006] On one hand, the present invention provides a calibration device for a paper cutting wheel of a cigarette machine, comprising: a connecting rod, one end of which is provided with a mounting hole, a first locking bolt passing through the mounting hole and threadedly connected to one end of the wheel axle of the paper cutting wheel, the other end of which is provided with a locking groove, one end of a brush shaft being installed in the locking groove and locked by a second locking bolt.

[0007] Preferably, a washer is provided between the head of the first locking bolt and the mounting hole, wherein the outer diameter of the washer is larger than the diameter of the mounting hole, and the diameter of the first locking bolt is smaller than the inner diameter of the washer.

[0008] Preferably, a keyway communicating with the inner wall of the mounting hole is provided.

[0009] Preferably, the length of the connecting rod is not less than the distance between the axes of the paper cutting wheel and the brush shaft.

[0010] Preferably, the locking groove is a circular groove with an opening on one side, through which one end of the brush shaft extends. Corresponding locking screw holes are provided on both sides of the opening of the locking groove, and the second locking bolt cooperates with the locking screw holes to lock one end of the brush shaft.

[0011] Preferably, the locking groove is a closed circular groove from which one end of the brush shaft extends. A locking screw hole is provided on the outer side wall of the locking groove, and the second locking bolt cooperates with the locking screw hole to lock one end of the brush shaft.

[0012] Preferably, the center distance between the mounting hole and the locking groove is equal to the distance between the axis of the paper cutting wheel and the axis of the brush shaft.

[0013] Preferably, the thickness of the connecting rod is not greater than the length of the protruding portion of the axle of the paper cutting wheel.

[0014] On the other hand, the present invention also provides a calibration method using the above-described calibration device, comprising the following steps: S1: Install the locking groove on the connecting rod into one end of the brush shaft; S2: Install the connecting rod by aligning the mounting hole with the axle of the paper cutting wheel; S3: Tighten the second locking bolt to lock the brush shaft; S4: Tighten the first locking bolt to lock it in place with the threaded connection of the paper cutting roller axle. At this time, the position of the paper cutting roller is precisely positioned. Rotate the blade roller to make any blade cut into the paper cutting roller and generate slight pressure. Tighten the positioning bolts of the blade roller to complete the calibration work.

[0015] Preferably, in step S4, the depth to which any blade cuts into the paper cutting wheel is 15mm ± 1mm.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The paper cutting wheel axle and the brush shaft are fixedly connected by the connecting rod and two slots, locking their position and allowing the cutter roller to cut into the paper cutting wheel, further preventing its rotation. This effectively solves the problems of displacement, misalignment, damage and unsafe factors that can easily occur during the daily maintenance and repair of the paper cutting wheel and cutter roller, such as the disassembly and installation of their parts. 2. Significantly improves maintenance and repair efficiency, shortens repair time, and reduces the overall repair time from about 1 hour to about 20 minutes to complete the calibration, greatly improving maintenance and repair efficiency; 3. It reduced the number of workers and equipment downtime, improved production efficiency, and ensured the completion of production tasks. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Example 1 like Figure 1-3 As shown, the present invention provides a calibration device for a paper cutting roller of a cigarette machine, comprising: a connecting rod 3, the length of which is not less than the distance between the axes of the paper cutting roller 2 and the brush shaft 1; a mounting hole 301 is provided at one end of the connecting rod 3; a first locking bolt 4 passes through the mounting hole 301 and is threadedly connected to one end of the axle of the paper cutting roller 2; a locking groove 302 is provided at the other end of the connecting rod 3; one end of the brush shaft 1 is installed in the locking groove 302 and locked by a second locking bolt 7; the above structure can fix the position of the paper cutting roller 2 during maintenance, preventing it from rotating, facilitating the calibration of the fastening screws on the cutter roller 5, and avoiding problems such as displacement, misalignment, damage, and safety hazards to the cutter roller and its components during disassembly and installation during maintenance.

[0023] Specifically, a washer 6 is provided between the head of the first locking bolt 4 and the mounting hole 301. The outer diameter of the washer 6 is larger than the diameter of the mounting hole 301, and the thread diameter of the first locking bolt 4 is smaller than the inner diameter of the washer 6. A keyway 303 communicating with the inner wall of the mounting hole 301 is provided. A key block is installed in the keyway 303 to prevent the first locking bolt 4 from slipping during use.

[0024] In this embodiment, the locking groove 302 is a circular groove with an opening on one side, and its diameter is slightly larger than the diameter of one end of the brush shaft 1. One end of the brush shaft 1 extends out from it. Corresponding locking screw holes are provided on both sides of the opening of the locking groove 302, and the two sides have a certain deformation capacity. The second locking bolt 7 is tightened in conjunction with the locking screw hole to lock one end of the brush shaft 1, ensuring that the brush shaft 1 and the paper cutting wheel 2 will not rotate relative to each other.

[0025] In this embodiment, the center distance between the mounting hole 301 and the locking groove 302 is equal to the distance between the axis of the paper cutting wheel 2 and the axis of the brush shaft 1. The thickness of the connecting rod 3 is not greater than the length of the protruding part of the axle of the paper cutting wheel 2.

[0026] In addition, the present invention provides a calibration method using the above-described calibration device, which includes the following steps: S1: Install the locking groove 302 on the connecting rod 3 into one end of the brush shaft 1, and insert one end of the second locking bolt 7 into the locking screw hole; S2: Install the connecting rod 3 with the axle of the paper cutting wheel 2, and install the washer 6 and the first locking bolt 4. S3: Tighten the second locking bolt 7 to lock the end of the brush shaft 1 in the locking groove 302; S4: Tighten the first locking bolt 4 to lock the threaded connection of the paper cutting wheel 2 to the wheel axle, so that the rotation position of the paper cutting wheel 2 is accurately positioned. This position is the initial calibration position. Install the blade roller 5, rotate the blade roller 5 so that any blade cuts into the cutting anvil of the paper cutting wheel 2 and generates slight pressure. Tighten each positioning bolt of the blade roller 5 to complete the calibration work.

[0027] In step S4 above, the depth to which any blade cuts into the paper cutting wheel 2 is 15mm ± 1mm. After the blade cuts into the paper cutting wheel 2, measure whether the point where the blade of the cutter roller 5 contacts the anvil of the paper cutting wheel 2 is 15mm from the near edge of the anvil. If not, loosen the bolts on the connecting rod 3, slightly rotate the paper cutting wheel 2 until the distance is 15mm, and then tighten the bolts on the connecting rod 3 and the paper cutting wheel 2 to completely fix the paper cutting wheel 2. At this time, the relative position phase between the cutter roller 5 and the paper cutting wheel 2 is correct. At this time, when tightening the bolts on the surface of the cutter roller 5, the paper cutting wheel 2 will not rotate relative to the blade. Then tightening the fixing bolts of the cutter roller 5 will complete the calibration work.

[0028] Example 2 The difference from Embodiment 1 is that in this embodiment, the locking groove 302 is a closed circular groove, one end of the brush shaft 1 extends out from it, and a locking screw hole is provided on the outer side wall of the locking groove 302, through which the second locking bolt 7 cooperates with the locking screw hole to lock one end of the brush shaft 1.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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 or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
