Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a cutter disc maintenance workbench. Background Art

[0002] The knife disc is an important mechanism in the cigarette forming process. The stability and sharpness of the knife disc directly affect the neatness of the cigarette end and the consistency of the cigarette length. The accurate maintenance of the knife disc is crucial to ensure the continuity of the cigarette production line and product quality. The blade is prone to wear or damage when cutting tobacco sticks for a long time under high-speed rotation, resulting in inaccurate cutting. In addition, the insufficient machining accuracy of the knife disc will cause the blade position to shift, resulting in uneven cutting.

[0003] In order to solve the above problems, a special maintenance workbench is needed to maintain the cutter disc. When adjusting the cutter box to maintain parallelism, contact detection technology is used, that is, measurement is performed through a micrometer that is in direct contact with the blade surface. However, the thin blade (thickness is about 0.15mm) leads to large contact measurement errors. At the same time, in order to meet the parallelism and clearance requirements, manual repeated tapping adjustments are required. The force and angle are difficult to adjust, and maintenance uniformity is difficult to guarantee.

[0004] Therefore, there is an urgent need for a cutter head maintenance workbench to solve the above problems. Utility Model Content

[0043] like Figure 1-Figure 5As shown, in this embodiment, the cutter disc maintenance workbench includes a bracket 1, a fixing mechanism 3, a detection component 4 and an adjustment component 5. Among them, the bracket 1 is arranged on the workbench 2, and the bracket 1 is used to fix the cutter disc 100. The fixing mechanism 3 includes a fixing seat 31 and a tightening component. The fixing seat 31 is arranged on the workbench 2 and is opposite to the bracket 1 and is arranged at intervals. The tightening component is arranged on the fixing seat 31 and can be extended and retracted relative to the fixing seat 31 to tighten the cutter disc 100. The detection component 4 is arranged on the bracket 1, and the detection component 4 is used to detect the parallelism of the blades in the cutter disc 100. The adjustment assembly 5 includes two adjustment screws 51, a first clamping member 52 and a second clamping member 53. The first clamping member 52 and the second clamping member 53 are respectively arranged on both sides of the cutter disc 100. The first clamping member 52 is provided with a first connection hole, and the first clamping member 52 is provided with a second connection hole. The adjustment screw 51 is sequentially passed through the fixing mechanism 3 and the first connection hole and connected to the second connection hole. The two adjustment screws 51 are used to adjust the position of the cutter disc 100 so that the blades in the cutter disc 100 reach the parallelism reference. Specifically, one end of the bracket 1 is fixedly mounted on the bracket 1, and the other end is used to fix the cutter disc 100. The clearance between the knife box of the cutter disc 100 and the bracket 1 is required to be 0.1-0.15 mm. The cutter disc 100 is located between the fixing seat 31 and the bracket 1. The pressing assembly can be extended and retracted relative to the fixing seat 31 so that the pressing assembly presses the cutter disc 100, so that the cutter disc 100 can be fixed on the bracket 1, and the cutter disc 100 is fixed and locked along the extension direction of the pressing assembly. After the knife disc 100 is centered, it is necessary to fine-tune the knife disc 100. The first clamping member 52 and the second clamping member 53 are buckled from both sides of the knife disc 100, and then the two adjusting screws 51 are sequentially inserted into the first connecting holes corresponding to the fixing mechanism 3 and the first clamping member 52 and are threadedly connected to the second connecting holes corresponding to the second clamping member 53. During the adjustment process of the two adjusting screws 51, the number of turns of one adjusting screw 51 is different from the number of turns of the other adjusting screw 51, so that the degree of parallelism of one side plane of the knife disc 100 relative to the other side plane is adjusted, and the parallelism of the blade in the knife disc 100 is detected by using the detection component 4, and the knife disc 100 is precisely adjusted by the adjustment component 5 until the parallelism of the blade meets the requirements. The knife disc 100 locks and fixes the blade, changes the original adjustment method that requires manual knocking, enhances the control accuracy of the adjustment, and avoids the micro-movement of the knife box and the fluctuation of parallelism detection caused by position adjustment. After the adjustment, the parallelism of the blade meets the accuracy requirements, ensuring the cutting quality of tobacco.

[0044] Further, continue to refer to Figure 1-Figure 5The tightening assembly includes a push rod 32 and a locking piece 33. The fixed seat 31 is provided with a through hole and a mounting hole. The mounting hole is connected to the through hole. The push rod 32 is slidably passed through the through hole and can be tightened to the cutter disc 100. The locking piece 33 is rotatably set on the fixed seat 31, and the locking piece 33 can pass through the mounting hole and the through hole and abut against the outer peripheral surface of the push rod 32 to fix the push rod 32 relative to the fixed seat 31. Specifically, after the cutter disc 100 is fixed, the push rod 32 is pushed and the push rod 32 slides through the through hole, that is, the push rod 32 slides relative to the fixing seat 31 so that the push rod 32 can be pressed against the cutter disc 100. After the cutter disc 100 is determined to be positioned and fixed under the action of the bracket 1 and the push rod 32, the locking member 33 is rotated and connected to the mounting hole of the fixing seat 31 and extends into the mounting hole. Then the locking member 33 can abut against the outer peripheral surface of the push rod 32, so that the push rod 32 is fixed relative to the fixing seat 31, thereby ensuring the good fixation of the cutter disc 100.

[0045] Further, continue to refer to Figure 1-Figure 5 The jacking assembly further includes a return spring 34, which is sleeved on the push rod 32, and the two ends of the return spring 34 are respectively in contact with the fixing seat 31 and one end of the push rod 32 close to the cutter disc 100. Specifically, after the parallelism adjustment and maintenance of the cutter disc 100 are completed, the locking member 33 is unlocked, and the push rod 32 is separated from the cutter disc 100 under the action of the return spring 34, so that the cutter disc 100 can be removed conveniently.

[0046] Further, continue to refer to Figure 1-Figure 5 The push rod 32 includes a sliding portion 321 and a clamping portion 322. The clamping portion 322 is connected to the sliding portion 321. The sliding portion 321 is slidably disposed in the through hole. The clamping portion 322 can abut against the cutter disc 100, and the two ends of the clamping portion 322 can respectively clamp and fix the two ends of the cutter disc 100. Specifically, the clamping portion 322 is a U-shaped structure, that is, the two ends of the clamping portion 322 can clamp and fix the two ends of the cutter disc 100. The sliding portion 321 can slide along the through hole under the action of external force. The sliding portion 321 is slidably matched with the fixed seat 31. The clamping portion 322 can abut against the outer periphery of the cutter disc 100 and clamp the cutter disc 100, ensuring that the cutter disc 100 is fixed while being fixed. Under the clamping action of the clamping portion 322, the cutter disc 100 can be fixed along its own length direction.

[0047] Further, continue to refer to Figure 1-Figure 5The cutter disc maintenance workbench also includes a driving mechanism 6, which includes a fixing frame 61 and a cylinder 62. The fixing frame 61 is installed on the fixing seat 31, and the cylinder 62 is arranged on the fixing frame 61. The cylinder 62 can drive the push rod 32 to move along the axial direction of the through hole. Specifically, when the cylinder 62 is started, the telescopic end of the cylinder 62 can press the push rod 32 tightly, so that the push rod 32 is pressed against the cutter disc 100, and the cutter disc 100 is fixed by the constant force of the cylinder 62, ensuring the consistency of each clamping of the cutter disc 100 and the repeatability of the positioning accuracy during adjustment, which can effectively simulate the installation position of the actual cutter disc 100.

[0048] Further, continue to refer to Figure 1-Figure 5 The cutter head maintenance workbench also includes a protective cover 7, which is rotatably arranged on the fixed seat 31, and the protective cover 7 can be arranged on the driving mechanism 6. The protective cover 7 is rotatably connected to the top of the fixed seat 31 through a hinge, and the protective cover 7 plays a protective role on the driving mechanism 6.

[0049] Further, continue to refer to Figure 1-Figure 5 , the detection component 4 includes a displacement sensor 41, an adjustment frame 42 and a support seat 43. The support seat 43 is fixedly mounted on the bracket 1. The two ends of the adjustment frame 42 are respectively connected to the support seat 43 and the displacement sensor 41. The adjustment frame 42 is used to adjust the deflection angle of the emitting surface of the displacement sensor 41. Specifically, the displacement sensor 41 is configured as a laser displacement sensor. The support seat 43 is fixed to the bracket 1 by a number of bolts. The displacement sensor 41 is magnetically connected to the support seat 43 through its own magnet, which is convenient for disassembly and installation. After the cutter disc 100 is fixed by the bracket 1 and the tightening component, the displacement sensor 41 is adjusted by the adjustment frame 42 so that the emitting surface of the sensor is opposite to the blade end face of the cutter disc 100, so as to accurately measure the parallelism of the blade in the cutter disc 100 in a non-contact manner, avoid the detection component 4 from affecting the parallelism of the blade, thereby improving the accuracy and efficiency of parallelism detection.

[0050] Further, continue to refer to Figure 1-Figure 5The cutter disc maintenance workbench also includes a mobile trolley 8, and the bracket 1 and the fixed seat 31 are both arranged on the mobile trolley 8. Specifically, the cutter disc maintenance workbench can be moved to the position where the cutter disc 100 is placed by the mobile trolley 8, and the operator does not need to carry the cutter disc 100 for a long distance, which saves time and effort. Optionally, the cutter disc maintenance workbench adds a clamping member, and fixes the driven pressure roller through the clamping member to ensure the consistency of the adjustment position and angle of the conveying roller, ensure the uniformity of the feed amount of the two knife boxes, and ensure the stable operation of the cutter disc 100. The cutter disc maintenance workbench can effectively improve the progress of various adjustments during the maintenance of the cutter disc 100, improve the working efficiency, and ensure the consistency and standardization of the cutter disc 100 maintenance process through the adjustment component 5 and the displacement sensor 41, thereby stabilizing the maintenance quality of the cutter disc 100, improving the operating stability of the cutter disc 100, and ensuring the continuity of the equipment production operation.

[0051] Further, continue to refer to Figure 1-Figure 5 The cutter disc maintenance workbench also includes a clamping device 9, which is arranged on the workbench 2 and is used to fix the pressure roller. Specifically, the cutter box is composed of two half cutter boxes, each half cutter box has two pressure rollers for fixing the blade, and the height, angle and pressure of the two pressure rollers should be as consistent as possible. Therefore, the position of the pressure roller is fixed by the clamping device 9 to ensure the consistency of the adjustment position and angle of the conveying roller, ensure the uniformity of the feed amount of the two half cutter boxes, and ensure the stable operation of the cutter disc 100.
