Description

Technical Field

[0001] The invention relates to the technical field of reconstituted tobacco production equipment, and more specifically to a device for assisting the installation of a reconstituted tobacco cutting knife roller. Background Art

[0002] Reconstituted tobacco refers to the recycled products in sheet or filament form made from the discarded tobacco stems, tobacco dust and broken tobacco flakes in the process of cigarette processing, which are used as cigarette fillers. Reconstituted tobacco plays an important role in cigarette production, not only reducing the cost of cigarettes, but also improving the intrinsic quality of cigarettes.

[0003] The shredding of reconstituted tobacco leaves is an important part of the process of reconstituted tobacco leaves. The shredding knife roller assembly is the main functional component for shredding. Due to aging and wear of the knife roller, it is generally necessary to regularly repair and replace the knife roller. In this process, adjusting the knife distance between the two knife rollers is a very critical step. If the knife distance is too large, it will cause the tobacco leaves to be shredded continuously. If the knife distance is too small, it will cause accelerated wear between the knife rollers. The adjustment of the knife distance is often made by experienced staff through experience. There is no standard adjustment process, which makes the process very time-consuming and labor-intensive. In addition, the optimal knife distances corresponding to knife rollers of different specifications are slightly different.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the present application, the X direction, the Y direction, and the Z direction are shown in the drawings.

[0035] The core of the present invention is to provide a device for assisting the installation of a reconstituted tobacco leaf cutting roller, which can assist the staff in installing the knife roller 01 and adjusting the spacing of the knife roller 01 when replacing and installing the knife roller 01, thereby improving the accuracy of adjusting the spacing of the knife roller 01, and can also reduce the labor intensity of the staff and increase the safety of work.

[0036] Please refer to Figure 1 A device for assisting the installation of a reconstituted tobacco leaf cutting roller comprises a tooling frame 1, a control device 2, a moving module 3 and a laser ranging component 4.

[0037] Specifically, a control device 2 is provided on the tooling frame 1, and a mobile module 3 is provided on the tooling frame 1. The tooling frame 1 provides an installation and support foundation for the mobile module 3 and the control device 2. The mobile module 3 includes a support structure 31 for supporting the knife roller 01, and the knife roller 01 whose spacing is to be adjusted is supported by the support structure 31. It also includes a driving device for driving the supporting structure 31 to move in two directions perpendicular to each other in a plane. The driving device is connected to the control device 2 by signal, and the control device 2 controls the operation of the driving device so that the supporting structure 31 moves perpendicular to each other in a plane. The laser distance measuring component 4 is arranged on the mobile module 3 and is connected with the control device 2 by signal. The laser distance measuring component 4 is used to measure the distance between the two knife rollers 01 in real time, and send the real-time measurement result to the control device 2. The control device 2 determines the spacing of the knife rollers 01. When the control device 2 determines that the spacing of the knife rollers 01 is adjusted, the control drive device stops running.

[0038] The tool frame 1 is the overall frame of the device, and a locking structure for fixing the control device 2 is provided on the tool frame 1. The bottom of the tool frame 1 is also provided with retractable universal wheels to adapt to different working scenes.

[0039] The device for assisting the installation of the reconstituted tobacco leaf cutting roller set up in the above manner controls the operation of the entire device through the control device 2 to achieve precise adjustment of the spacing between the rollers 01 of different lengths. Compared with the existing manual spacing adjustment method, the accuracy of the spacing adjustment can be improved, the labor intensity of the staff can be reduced, the safety of the work can be increased, and the work efficiency can be improved.

[0040] In the above embodiment, the driving device includes two groups of first driving modules 32 and two groups of second driving modules 33 arranged on the tooling frame 1. The top surface of the tooling frame 1 is the mounting surface. The first driving module 32 extends along the X direction of the mounting surface, and the second driving module 33 extends along the Y direction of the mounting surface. The second driving module 33 is movably arranged on the first driving module 32, and the supporting structure 31 is movably arranged on the second driving module 33.

[0041] It should be noted that the second drive module 33 drives the support structure 31 fixed thereon to move, thereby driving the adjustable knife roller 01 to move and thus adjusting the knife distance. The first drive module 32 drives the second drive module 33 to move to change the width between the two groups of second drive modules 33, thereby adapting to the replacement and installation of cutting knife rollers 01 of different length specifications.

[0042] Please refer to Figure 2The first driving module 32 includes two first guide rails 321 extending along the X direction, and the two first guide rails 321 are arranged in a line. The first guide rails 321 are each provided with a first slider 322 sliding along the first guide rails 321. The first slider 322 is driven by a first motor 323 at one end of the first guide rail 321. The first motor 323 is connected to the control device 2 by signal. A limit plate 34 is provided at the other end of the first guide rail 321. The second driving module 33 includes a second guide rail 331 extending along the Y direction. Both ends of the second guide rail 331 are fixed on the first slider 322.

[0043] It can be understood that the first motor 323 is controlled by the control device 2 to drive the slider on the first guide rail 321 to slide along the first guide rail 321, thereby driving the second guide rail 331 on the first slider 322 to move along the X direction, thereby changing the distance between the two second guide rails 331, thereby adapting to the replacement and installation of the shredding knife roller 01 of different length specifications.

[0044] Furthermore, the second guide rail 331 is provided with a second slider 332 that slides along the second guide rail 331. The second slider 332 is driven by a second motor 333 at one end of the second guide rail 331. The second motor 333 is connected to the control device 2 by signal. A limit plate 34 is provided at the other end of the second guide rail 331. A fixed block 334 is also provided on the second guide rail 331. The fixed block 334 is arranged close to the limit plate 34. A support structure 31 is provided on both the second slider 332 and the fixed block 334.

[0045] It should be noted that the second motor 333 is controlled by the control device 2 to drive the second slider 332 on the second guide rail 331 to slide along the Y direction, driving the support structure 31 on the second slider 332 to move toward or away from the fixed block 334, thereby changing the distance between the two knife rollers 01 and adjusting the knife spacing of the knife roller 01.

[0046] Among them, the fixed block 334 on the second guide rail 331 is fixed, and the second slider 332 on the second guide rail 331 is slidable, that is, the knife roller 01 supported by the support structure 31 on the fixed block 334 on the two second guide rails 331 is fixed, and the knife roller 01 supported by the support structure 31 on the second slider 332 on the two second guide rails 331 is movable. Therefore, the second motor 333 is controlled by the control device 2 to drive the second slider 332 to move, drive the support structure 31 on the second slider 332 to move, and thus drive the knife roller 01 to move, so as to adjust the knife distance.

[0047] In the above embodiment, the support structure 31 includes a support block for supporting the rotating shaft of the knife roller 01, and a circular bracket is provided on the top of the support block, and the top of the support block is located above the center of the circular bracket.

[0048] It is understandable that the support block is arranged on the fixed block 334 and the second slider 332, and its circular bracket can hold the central axis of the knife roller 01, thereby driving the knife roller 01 to move and adjust the knife distance. It is preferred to set the top of the support block to a position higher than the center of the circular bracket, so as to increase the support of the support block to the knife roller 01.

[0049] Among them, in this embodiment, the support block is fixedly connected to the fixed block 334 and the second slider 332, but in actual application, it can also be set to a detachable connection mode, by replacing the support block with circular brackets of different specifications to adapt to the installation of knife rollers 01 of different specifications.

[0050] On the basis of the above embodiment, at least two circular brackets with different diameters are provided on the support block, and at least two circular brackets are arranged in parallel.

[0051] It should be noted that, by providing two or more circular brackets with different diameters on a support block, it is possible to adjust the distance of knife rollers 01 of various specifications.

[0052] In the above embodiment, the laser ranging assembly 4 includes a laser rangefinder 41 and a baffle plate 42. The laser rangefinder 41 is arranged on the second slider 332, and the baffle plate 42 is arranged on the fixed block 334. The laser rangefinder 41 and the baffle plate 42 are arranged on the same second guide rail 331, and one end of the laser rangefinder 41 emitting the laser beam is directed toward the baffle plate 42.

[0053] It can be understood that the laser rangefinder 41 is set on the second slider 332 and moves with the second slider 332, the baffle plate 42 is set on the fixed block 334, and the laser rangefinder 41 can measure the distance between the laser rangefinder 41 and the baffle plate 42 in real time and transmit the data to the control device 2.

[0054] As a preferred embodiment, at least two laser rangefinders 41 are provided, and the at least two laser rangefinders 41 are respectively disposed on the corresponding second sliders 332 , and two shielding plates 42 are correspondingly provided and disposed on the corresponding fixing blocks 334 .

[0055] It should be noted that at least two laser rangefinders 41 are provided, which are respectively arranged on the corresponding second sliders 332 to improve the measurement accuracy.

[0056] In the above case, a sensor connected to the control device 2 by signal is also included, and the sensor is used to detect the distance between the two second sliding blocks 332 in real time.

[0057] It can be understood that the distance between the two second sliders 332 is detected in real time by the sensor, and the detected distance data is sent to the control device 2, and the control device 2 further controls the operating state of the first motor 323 to adjust the distance between the two second sliders 332, and then adjust the distance between the support blocks used to support the knife roller 01, so as to be suitable for the adjustment of knife rollers 01 of different lengths.

[0058] In the above embodiment, the control device 2 includes an operation screen for inputting instructions and displaying detection results, and also includes a control board for receiving input instructions and receiving signals from the laser ranging component 4 and the sensor, and the operation screen is connected to the control board.

[0059] It should be noted that the length value and the blade spacing value of the knife roller 01 to be adjusted are input through the operation screen. After the control panel receives the input numerical signal, it issues a control instruction to control the operation of the first motor 323 to adjust the distance between the two second guide rails 331. At the same time, the distance between the two second guide rails 331 is detected by the sensor, and the detected data signal is sent to the control panel. The operation state of the first motor 323 is controlled by the control panel until the second guide rail 331 moves to the input distance, and the knife roller 01 is placed on the support block on the second guide rail 331. The operation of the second motor 333 is controlled by the control panel to drive the knife roller 01 on the second slider 332 to move, thereby adjusting the distance between the two knife rollers 01. At the same time, the distance between the laser rangefinder 41 and the baffle 42 is measured in real time by the laser rangefinder 41, and the data is transmitted to the control panel and the operation screen. The operation state of the second motor 333 is controlled by the control panel until the blade spacing of the knife roller 01 is consistent with the input value.

[0060] The laser rangefinder 41 can measure the distance between the laser rangefinder 41 and the shielding plate 42 in real time, and transmit the data to the operation screen. Generally, there are different optimal values ​​for the spacing between the knife rollers 01 of different specifications. The staff inputs different knife roller parameters on the operation screen, and the first drive module 32 automatically adjusts the width. After the staff hoist the two knife rollers 01 to the circular bracket of the support block, the second drive module 33 works to adjust the knife spacing between the two knife rollers 01 to the optimal value, and then the staff installs the side plate 02 of the slitting knife roller 01. Figure 3 As shown, automatic adjustment of the tool distance is achieved.

[0061] The operation screen is arranged on the tooling frame 1, and can display the distance between the laser rangefinder 41 and the shielding plate 42. The auxiliary installation of the knife roller 01 and the automatic adjustment of the knife distance can be realized by inputting the parameters of the knife roller 01 of different specifications. An emergency stop button is also arranged on the operation screen, which is used to quickly stop the movement of all the mobile modules 3 in an emergency.

[0062] In summary, the device for assisting the installation of the reconstituted tobacco leaf cutting roller provided by the present invention can assist the staff in installing the cutting roller 01 and adjusting the blade spacing when the cutting roller 01 is replaced and installed, thereby reducing the labor intensity of the staff and increasing the safety of work. At the same time, it can adapt to the replacement and installation of cutting rollers 01 of different length specifications, greatly improving work efficiency.

[0063] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0064] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
