Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a device for verifying the parallelism of the blades of a tobacco package slicing machine. Background Technology

[0002] In the tobacco slicing process of tobacco production, the parallelism of the slicer blades directly affects the quality and consistency of the sliced ​​tobacco. The blades are mounted on a blade mounting frame, which is slidably mounted on the frame of the slicer at both ends via rollers. The rollers at the ends of the blade mounting frame can slide vertically along the slide rails of the frame, and are driven by two sets of chain mechanisms to raise and lower the left and right ends of the blade mounting frame on the frame, thereby adjusting the blade mounting position.

[0003] During long-term operation, tobacco slicing machines are prone to unevenness in the left and right ends of the blade mounting bracket due to factors such as mechanical vibration, blade wear, loose blade holder, and natural attenuation of installation accuracy. This unevenness causes the mounting bracket to tilt, resulting in tilted blades. Traditional detection methods rely heavily on manual observation or rough measurement with measuring tools, making it difficult to accurately quantify blade parallelism errors. Furthermore, the lack of efficient and accurate adjustment methods leads to low equipment maintenance efficiency, significant product quality fluctuations, and an inability to meet the stringent requirements of high precision and high quality in modern tobacco production. Therefore, developing an efficient, accurate blade parallelism calibration device for tobacco slicing machines that requires no major equipment modifications is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for verifying the parallelism of tobacco slicing machine blades, so as to achieve accurate and efficient verification of the parallelism of the slicing machine blades and ensure that the slicing machine blades maintain a good parallelism state.

[0005] This utility model is achieved through the following technical solution: A parallelism calibration device for a cigarette pack slicing machine blade is disclosed. The blade is mounted on a blade mounting frame, and the left and right ends of the blade mounting frame are respectively mounted on the left and right columns of the slicing machine frame. The lower section of the columns is provided with a mounting step. The calibration device includes a mounting plate detachably mounted on the mounting step, and a calibration body is provided on the mounting plate. The top surface of the calibration body is a horizontal calibration surface. A vertically extending groove is opened on the top of the calibration body, and a measuring plate is slidably arranged in the groove. The vertical dimension of the groove is greater than the height of the measuring plate. A horizontally extending indicator needle is provided on one side of the measuring plate, and a clearance groove is opened on one side of the calibration body for the indicator needle to extend out. The indicator needle can slide vertically in the clearance groove. A scale is provided on the calibration body next to the clearance groove, and the scale has vertical graduation lines.

[0006] As a preferred embodiment of the above-mentioned cigarette pack slicing machine blade parallelism verification device, the mounting plate has several through holes, which correspond one-to-one with several buffer rubber pad mounting holes on the mounting step. The mounting plate and the mounting step are connected by passing bolts through the through holes and buffer rubber pad mounting holes in sequence and tightening nuts.

[0007] As a preferred embodiment of the above-mentioned cigarette pack slicing machine blade parallelism verification device, the indicator needle is located on one side of the bottom end of the measuring plate.

[0008] As a preferred embodiment of the above-mentioned cigarette pack slicing machine blade parallelism verification device, the zero point of the vertical scale line on the scale is set close to the bottom of the scale. When the indicator needle of the measuring plate is aligned with the zero point of the scale, the top surface of the measuring plate is exactly flush with the verification surface of the verification body.

[0009] This invention has the following advantages over the prior art: This utility model provides a parallelism verification device for cigarette pack slicing machine blades. The device verifies the height of the left and right ends of the blade mounting frame by means of the verification surface on the top of the verification body. When the height of the left and right ends of the blade mounting frame is found to be inconsistent, the height difference between the left and right ends of the blade mounting frame can be directly read by sliding the measuring plate and relying on the indicator needle on the measuring plate and the measuring ruler. This serves as the basis for subsequent adjustments, achieving accurate, efficient, and rapid verification of the parallelism of the blades installed on the blade mounting frame. This ensures that the slicing machine blades maintain a good parallelism state, thereby ensuring the stability of its working state. Attached Figure Description

[0013] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0014] See Figures 1 to 2This embodiment discloses a parallelism calibration device for a cigarette pack slicing machine blade. The blade 1 is mounted on a blade mounting frame 2. The left and right ends of the blade mounting frame 2 are respectively mounted on the left and right columns 3 of the slicing machine frame. The lower section of the column 3 is provided with a mounting step 4. The calibration device includes a mounting plate 5 that is detachably mounted on the mounting step 4. The mounting plate 5 has several through holes 6, which correspond one-to-one with several buffer rubber pad mounting holes on the mounting step 4. The mounting plate 5 and the mounting step 4 are connected by bolts passing through the through holes 6 and buffer rubber pad mounting holes in sequence and tightening the nuts.

[0015] The mounting plate 5 is provided with a calibration body 7, the top surface of which is a horizontal calibration surface 8. A vertically extending groove 9 is opened on the top of the calibration body 7, and a measuring plate 10 is slidably disposed in the groove 9. The vertical dimension of the groove 9 is greater than the height of the measuring plate 10. A horizontally extending indicator needle 11 is provided on one side of the measuring plate 10. In this embodiment, the indicator needle 11 is located on the bottom side of the measuring plate 10. A clearance groove 12 is opened on one side of the calibration body 7 for the indicator needle 11 to extend out. The indicator needle 11 can slide vertically in the clearance groove 12. A scale 13 is provided on the calibration body 7 next to the clearance groove 12, and the scale 13 has vertical scale lines 14. The zero point of the vertical scale line 14 on the scale 13 is set close to the bottom of the scale 13. When the indicator needle 11 of the measuring plate 10 is aligned with the zero point of the scale 13, the top surface of the measuring plate 10 is exactly flush with the verification surface 8 of the verification body 7, so that the extension of the measuring plate 10 above the verification surface 8 of the verification body 7 can be directly read from the scale 13.

[0016] When the slicer is working normally, buffer rubber pads are installed on the mounting steps 4 of the two uprights 3 on the left and right sides of the frame. The two buffer rubber pads provide cushioning support for the bottom surfaces of the left and right ends of the descending blade mounting frame 2. The buffer rubber pads are installed by passing bolts through the buffer rubber pads and the mounting holes of the buffer rubber pads and tightening the nuts to install the buffer rubber pads on the mounting steps 4.

[0017] When it is necessary to verify the parallelism of blade 1, first remove the two rubber buffer pads and install the two sets of verification devices on the mounting steps 4 of the two columns 3 respectively. Control the left and right ends of the blade mounting frame 2 to descend slowly at the same time. If the left and right ends of the blade mounting frame 2 simultaneously contact the verification surface 8 at the top of the verification block of the left and right sets of verification devices, it means that the left and right heights of the blade mounting frame 2 are consistent and no adjustment is needed. If one end of the left and right ends of the blade mounting frame 2 contacts the verification surface 8 of the corresponding side verification block, while the other end of the left and right ends of the blade mounting frame 2 does not contact the verification surface 8 of the corresponding side verification block and is not in a suspended state, it means that the left and right heights of the blade mounting frame 2 are inconsistent and the suspension distance of the suspended end needs to be measured. The measurement method is as follows: push the measuring plate 10 upward so that the measuring plate 10 extends upward above the calibration surface 8 of the calibration body 7 until the measuring plate 10 contacts the bottom surface of the suspended blade mounting bracket 2. At this time, the extension amount of the measuring plate 10 can be quickly and intuitively read through the scale 13. This extension amount is the height difference between the two ends of the blade mounting bracket 2, which serves as the basis for subsequent adjustment of the position of the two ends of the blade mounting bracket 2.

[0018] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
