Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production equipment, in particular to a guard plate device arranged between a cutting wheel and a separating wheel. Background Art

[0002] The function of the cutting wheel in a cigarette making machine is to align the double-length cigarette rod transmitted by the cigarette receiving wheel in the middle of the puff, and then a cutting knife arranged outside the cutting wheel cuts the double-length cigarette into two halves towards the middle of the cutting wheel; the separating wheel is used to receive the two cut cigarette rods and further separate and transfer them to the next packaging process; therefore, the cutting wheel and the separating wheel are usually installed close to each other in the cigarette making machine.

[0003] In order to prevent the cutting wheel and the separating wheel from splashing glue scale and tobacco dust towards each other during operation, resulting in the cutting wheel and / or the separating wheel getting stuck in rotation, technicians usually set up a protective plate for isolation at the corresponding position between the cutting wheel and the separating wheel. By making the protective plate extend into the cigarette cutting groove of the cutting wheel and block one side of the separating wheel, an effective isolation and protection is formed, and the cigarette rod on the cutting wheel is also guided to prevent the cigarette rod from falling, ensuring its smooth transportation between the cutting wheel and the separating wheel.

[0004] However, since the existing isolation protective plates are usually directly fixedly installed, when maintenance personnel perform maintenance on the cutting wheel and the separating wheel of the cigarette making machine each time, they first need to manually remove the two guard plates and the cutting wheel cleaning piece located between the cutting wheel and the separating wheel, and then the separating wheel and the cutting wheel can be removed in sequence; after the two drums are maintained and installed, the two guard plates and the cutting wheel cleaning piece need to be reinstalled in place. The entire installation process is rather cumbersome, and the guard plates often tilt during installation, resulting in the guard plates being inconsistent with their original positions, affecting the production schedule. Content of the Utility Model

[0005] The utility model provides a guard plate device arranged between a separating wheel and a cutting wheel. By enabling the guard plate assembly to move up and down, it is not necessary to remove the guard plate when maintaining the separating wheel and the cutting wheel, reducing the labor intensity of technicians and preventing the position deviation of the guard plate assembly after disassembly and reinstallation; moreover, technicians only need to lift the guard plate assembly away from the cutting wheel and the separating wheel to wipe and clean the guard plate assembly, and there is no need to remove the guard plate either, so as to solve the above technical problems.

[0006] The technical solution of the present utility model to solve the above problems is: to provide a guard plate assembly disposed between a slitting wheel and a separating wheel, including a guard plate device, a lifting cylinder, a sliding seat, and a first base. The lifting cylinder is fixedly installed at the upper end of the first base, the sliding seat is installed at the output telescopic shaft end of the lifting cylinder, the guard plate device is installed on the sliding seat, and the lifting cylinder drives the guard plate device to move up and down through the sliding seat to move away from or extend into the space between the slitting wheel and the separating wheel.

[0007] Further, the guard plate assembly includes a front guard plate, a scraper, a rear guard plate, and a mounting main shaft. The mounting main shaft is horizontally and fixedly installed on the side wall of the sliding seat. The front guard plate, the scraper, and the rear guard plate are axially and sequentially fixedly arranged on the mounting main shaft. Both the front guard plate and the rear guard plate are used to extend into the space between the slitting wheel and the separating wheel to prevent cigarette rods from falling out from the surface of the wheels, and the scraper is used to contact the side surface of the circular cutting knife of the slitting wheel to clean the adhesive scale and tobacco dust on the surface of the cutting knife.

[0008] Further, the lifting cylinder is a magnetic coupling cylinder.

[0009] Further, it further includes a second substrate fixedly installed on one side of the first base, and a control switch installed on the second substrate for controlling the operation or shutdown of the lifting cylinder.

[0010] Further, a limit end plate for controlling the stroke of the sliding seat is provided at the lower end of the first base.

[0011] Further, a detection sensor for detecting the position of the sliding seat is further provided on the corresponding end surface of the limit end plate for contacting the sliding seat.

[0012] Further, the control switch is also electrically connected to the detection sensor, and the control switch controls the shutdown of the lifting cylinder according to the detection signal of the detection sensor.

[0013] Further, the detection sensor is a pressure sensor.

[0014] The beneficial effects of the present utility model:

[0015] For a guard plate device of the present utility model disposed between a slitting wheel and a separating wheel, by installing the guard plate assembly at the output telescopic shaft end of the lifting cylinder, the guard plate assembly can correspondingly move downward under the drive of the lifting cylinder to extend into the gap between the slitting wheel and the separating wheel, thereby separating and protecting the slitting wheel and the separating wheel. The guard plate assembly can also move upward under the drive of the lifting cylinder to move away from the slitting wheel and the separating wheel, thus facilitating technicians to disassemble and install the slitting wheel and the separating wheel.

[0016] In addition, on the basis that the guard plate assembly can be lifted and moved, the utility model also installs a detection sensor on the upper end face of the limit end plate and connects the detection sensor with the control switch. As a result, each time the guard plate assembly descends to the lower limit end plate, it can be accurately detected by the detection sensor, and the control switch can correspondingly control the guard plate assembly to hover in time, so that the guard plate assembly can hover at the same position each time, thus avoiding the problem of inaccurate position when the guard plate assembly extends between the slitting wheel and the separating wheel again.

[0020] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may accordingly change depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0021] Please refer to Figure 1, a guard plate device provided between a slitting wheel and a separating wheel in a specific embodiment of the present utility model, includes a guard plate assembly 1, a lifting cylinder 2, a sliding seat 3, and a first base 4. The first base 4 is fixedly installed on the body structure of the cigarette making machine through a horizontally arranged fixed shaft body. The first base 4 is a vertically arranged plate body. The lifting cylinder 2 is fixedly installed at the upper end of the front side wall of the first base 4. The output telescopic shaft of the lifting cylinder 2 is vertically downward. The sliding seat 3 is installed at the end of the output telescopic shaft of the lifting cylinder 2. The guard plate assembly 1 is fixedly installed on the front side wall of the sliding seat 3 by bolts. In this regard, the guard plate assembly 1 can vertically move up and down under the drive of the lifting cylinder 2. When it is necessary to disassemble, maintain, and service the slitting wheel and the separating wheel, technicians can first control the guard plate assembly 1 to rise away from the slitting wheel and the separating wheel through the lifting cylinder 2, so that technicians can perform operations such as disassembling, maintaining, and installing the separating wheel and the slitting wheel without disassembling the guard plate assembly 1. In addition, after maintaining the separating wheel and the slitting wheel, technicians can again control the guard plate assembly 1 to vertically move downward to a predetermined position through the lifting cylinder 2, so that the guard plate assembly 1 can function normally.

[0022] In this embodiment, the guard plate assembly 1 includes a front guard plate 11, a scraper 12, a rear guard plate 13, and a mounting main shaft. One end of the mounting main shaft is fixedly installed on the side wall of the sliding seat 3 through a flange structure. The mounting main shaft is also horizontally arranged. The rear guard plate 13, the scraper 12, and the front guard plate 11 are fixedly installed on the mounting main shaft in sequence. In addition, although the specific positions of the front guard plate 11, the scraper 12, and the rear guard plate 13 on the mounting main shaft will change due to the structural dimensions of the slitting wheel, it can be determined that when the guard plate assembly 1 is working normally, both the front guard plate 11 and the rear guard plate 13 extend downward between the slitting wheel and the separating wheel, and part of the plate bodies of both the front guard plate 11 and the rear guard plate 13 also extend above the smoke grooves of the slitting wheel to prevent cigarette rods from falling out of the wheel surface. The scraper 12 is located on the side of the circular cutting knife of the slitting wheel and contacts it, so as to clean the adhesive scale and tobacco dust on the surface of the cutting knife.

[0023] In this embodiment, the lifting cylinder 2 is a magnetic coupling cylinder; however, in other embodiments, the lifting cylinder 2 can also be an ordinary cylinder.

[0024] Further, please refer to Figure 1 , in this embodiment, a second base plate 5 is further provided at the rear of the right side of the first base 4. The second base plate 5 is an L-shaped plate body. A control switch 6 is installed on the second base plate 5. The control switch 6 has both a manual control module and an electric control module. The control switch 6 is used to control the operation or shutdown of the lifting cylinder 2.

[0025] Specifically, the manual control module of the control switch 6 has three control potentials. One potential is used to control the shortening of the lifting cylinder 2, one potential is used to control the extension of the lifting cylinder 2, and one potential is used to control the lifting cylinder 2 to stop. Technicians can manually move the electric rod to the corresponding potential position to correspondingly control the extension, shortening, and stopping of the lifting cylinder 2, so as to drive the guard plate assembly 1 to move downward, upward, and hover.

[0026] In addition, in order to enable the guard plate assembly 1 to descend to the same height position each time, a limit end plate 7 is provided at the lower end of the front side of the first base 4, and a detection sensor 8 is provided on the upper end surface of the limit end plate 7. The detection sensor 8 is also electrically connected to the electric control module of the control switch 6 correspondingly.

[0027] Therefore, whenever the sliding seat 3 moves downward to the position where it contacts the limit end plate 7, the detection sensor 8 correspondingly generates an electrical signal by contacting the sliding seat 3 and transmits the electrical signal to the control switch 6. The electric control module in the control switch 6 only has one potential for controlling the lifting cylinder 2 to stop. The electrical signal sent by the detection sensor 8 to the control switch 6 is correspondingly used to control the lifting cylinder 2 to stop, so that the sliding seat 3 and the guard plate assembly 1 can hover at the limit end plate 7 each time, so that the guard plate assembly 1 hovers at the established height position each time, so as to ensure that the guard plate assembly 1 extends between the slitting wheel and the separating wheel at the same position as the previous extension each time.

[0028] In this embodiment, the detection sensor 8 is a pressure sensor.

[0029] For those not mentioned above, the prior art is applicable.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
