Description

Technical Field

[0001] The present invention relates to the field of tobacco machinery, and more particularly to a base rod compression amount adjusting device. Background Art

[0002] In recent years, with the strong competitive advantage and increasing popularity of new heat-not-burn tobacco products, especially granular heat-not-burn cigarette sticks, in the international market, such granular heat-not-burn cigarette sticks have gained more and more favor among the general public.

[0003] The structure of such granular heat-not-burn cigarette sticks is as Figure 1 shown. Its inner layer consists of a sealing layer 01, a granular section 02, a barrier section 03, a cooling section 04, a filtering section 05, and a cavity section 06. The outer shape is a cylindrical paper tube, and the outer surface of the shape is completely wrapped by a trademark paper of the same length as the paper tube. The sealing layer is formed by bonding a circular paper film to one end of the paper tube. The granular section is composed of flowing solid particles. The filtering section and the barrier section are cylindrical fasteners with different hardnesses. The cooling section can be in various forms such as a cavity, particles, and fasteners. The granular section, the barrier section, the cooling section, and the filtering section are sequentially filled into the paper tube from the cavity section of the paper tube as the inlet.

[0004] After the cigarette stick is wrapped, it is usually necessary to perform laser drilling on the circumferential surface of the cigarette stick to improve the draw resistance of the cigarette stick. During laser drilling, the center of the cigarette stick rolls from one suction slot on the drum to the next suction slot under the action of the cigarette pushing roller. The cigarette stick rotates on the outer surface of the drum, and laser drilling is completed during the rotation of the cigarette stick. During this process, the spatial position of the cigarette stick can remain stationary. However, the extrusion of the cigarette pushing roller and the drum on the cigarette stick during this process is inevitable. If the compression amount is too small, the movement delivery function between the suction slots of the cigarette stick cannot be normally completed. But if the compression amount is too large, the film at the sealing part will separate from the paper tube during the deformation of the cigarette stick paper tube, resulting in a breakage phenomenon. Thus, the particles inside the cigarette stick will leak out and stick firmly to the hub, further affecting the appearance of the cigarette stick, increasing the breakage rate and reject rate of the cigarette stick.

[0005] For those skilled in the art, how to keep the extrusion of the cigarette pushing roller and the drum on the cigarette stick within a suitable range and reduce the reject rate is a technical problem that needs to be solved currently. Summary of the Invention

[0038] Base rod 5. Specific embodiments

[0039] The core of the present invention lies in providing a base rod compression amount adjusting device, which keeps the extrusion of the base rod by the drum assembly and the smoke deflecting assembly within a suitable range, thereby reducing the rejection rate.

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the base rod compression amount adjusting device of the present invention will be introduced and described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Combined with Figures 2 to 5 As shown, the present invention provides a base rod compression amount adjusting device, which includes a drum assembly 1 and a smoke deflecting assembly 2. The drum assembly 1 and the smoke deflecting assembly 2 cooperate with each other to rotate the base rod 5. The base rod 5 has a cylindrical structure and is a semi-finished product for making cigarettes. For the convenience of description, the base rod can also be referred to as a cigarette.

[0042] The drum assembly 1 includes a transmission wheel 1.4 rotatably mounted on a wall panel 1.1. The wall panel 1.1 is a support structure, which is in the shape of a vertical plate or a frame structure and plays a main supporting role. The transmission wheel 1.4 can rotate relative to the wall panel 1.1, and the axis of the transmission wheel 1.4 extends along its length direction. A receiving groove for receiving the base rod 5 is provided on the outer surface of the transmission wheel 1.4. The receiving groove is a long strip-shaped groove structure, and the length direction of the receiving groove is arranged along the axis direction of the transmission wheel 1.4. The receiving groove forms a depression along the radial direction of the transmission wheel 1.4, and the depth of the receiving groove is less than the diameter of the base rod 5. The base rod 5 can be placed in the receiving groove. A rolling surface for the base rod 5 to roll is provided between adjacent receiving grooves. After the starting rail 2.2 pulls the base rod 5 out of the receiving groove, the base rod 5 can roll on the rolling surface, and the base rod 5 rotates circumferentially by itself. This process is self-rotation. A plurality of receiving grooves are provided on the transmission wheel 1.4. The base rod 5 is pulled out of one receiving groove and enters the next receiving groove. The base rod 5 rolls on the rolling surface between the two receiving grooves. During this process, the base rod 5 rotates circumferentially by itself. This process can be used for laser drilling on the surface of the base rod 5.

[0043] The cigarette pushing component 2 includes structures such as a cigarette pushing roller 2.1, a starting rail 2.2, a driving shaft 2.3, a support plate 2.7, a rolling driver 2.9, and a lifting driver 2.11. The cigarette pushing roller 2.1 is a columnar structure, and the axis direction of the cigarette pushing roller 2.1 is parallel to the axis direction of the transfer wheel 1.4. A plurality of starting rails 2.2 protrude from the outer surface of the cigarette pushing roller 2.1. The diameter of the cigarette pushing roller 2.1 is usually smaller than the diameter of the transfer wheel 1.4. The starting rail 2.2 is a structure protruding from the outer surface of the cigarette pushing roller 2.1. The starting rail 2.2 can be a whole long strip-shaped block structure extending along the axis direction of the cigarette pushing roller 2.1, or can adopt a group of separated convex blocks distributed along the axis direction of the cigarette pushing roller 2.1. This group of convex block structures can be regarded as a cigarette pushing roller 2.1. These specific setting forms should all be included in the protection scope of the present invention. At least one starting rail 2.2 is provided on one cigarette pushing roller 2.1, but usually two or more starting rails 2.2 are provided.

[0044] The starting rail 2.2 is used to push out the base rod 5 from the accommodation groove. The outer surface of the cigarette pushing roller 2.1 cooperates with the rolling surface to place the base rod 5; the depth of the accommodation groove is smaller than the diameter of the base rod 5, so a part of the base rod 5 necessarily protrudes outside the accommodation groove. Since the starting rail 2.2 protrudes from the outer surface of the cigarette pushing roller 2.1, when the cigarette pushing roller 2.1 drives the starting rail 2.2 to rotate and the starting rail 2.2 reaches the accommodation groove, the starting rail 2.2 contacts the base rod 5 and applies a force to the base rod 5, so that the base rod 5 is moved out of the accommodation groove. The base rod moved out of the accommodation groove contacts the outer surface of the cigarette pushing roller 2.1 and the outer surface of the transfer wheel 1.4 at the same time. The outer surfaces of the cigarette pushing roller 2.1 and the transfer wheel 1.4 form a certain degree of extrusion on the base rod 5 and cause the base rod 5 to rotate.

[0045] The cigarette pushing roller 2.1 is rotatably installed on the support plate 2.7 through the driving shaft 2.3. The output end of the rolling driver 2.9 is connected to the driving shaft 2.3 and drives the cigarette pushing roller 2.1 to rotate; the rolling driver 2.9 can adopt a motor. When the rolling driver 2.9 outputs rotation, it can drive the driving shaft 2.3 to rotate, and then the cigarette pushing roller 2.1 rotates synchronously. The rotation of the cigarette pushing roller 2.1 drives the starting rail 2.2 to rotate around the axis of the cigarette pushing roller 2.1. When the starting rail 2.2 contacts the base rod 5, it can push out the base rod 5 from the accommodation groove and cause the base rod 5 to roll on the surface of the cigarette pushing roller 2.1 and the surface of the transfer wheel 1.4, so as to realize the rotation of the base rod 5 itself.

[0046] The fixed part of the lifting drive 2.11 is installed on the wall panel 1.1. The output part of the lifting drive 2.11 is used to drive the support plate 2.7 to move, so as to change the distance between the smoke deflector roller 2.1 and the transfer wheel 1.4. The lifting drive 2.11 can adopt structures such as a servo electric cylinder or a lead screw. Since the smoke deflector roller 2.1 is installed on the support plate 2.7 through structures such as the drive shaft 2.3, when the support plate 2.7 is driven by the lifting drive 2.11, the drive shaft 2.3 can be moved. The moving direction of the support plate 2.7 is perpendicular to the axis direction of the smoke deflector roller 2.1. Therefore, the distance between the smoke deflector roller 2.1 and the transfer wheel 1.4 can be changed, and the distance between the smoke deflector roller 2.1 and the transfer wheel 1.4 can be increased or decreased.

[0047] When the smoke deflector roller 2.1 and the transfer wheel 1.4 rotate relative to each other and the base rod 5 rotates self, the distance between the smoke deflector roller 2.1 and the transfer wheel 1.4 is slightly smaller than the diameter of the base rod 5. The smoke deflector roller 2.1 and the transfer wheel 1.4 exert a certain degree of extrusion on the base rod 5. When the compression amount of the base rod 5 is too large, the base rod 5 is easily broken. When the compression amount of the base rod 5 is too small, the base rod 5 cannot punch holes normally or there is a phenomenon of flying smoke. The control unit controls the telescopic amount of the output part of the lifting drive 2.11, so as to adjust the distance between the smoke deflector roller 2.1 and the transfer wheel 1.4, and keep the distance between the smoke deflector roller 2.1 and the transfer wheel 1.4 within a reasonable range, which can not only meet the normal rotation of the base rod 5, but also avoid the base rod 5 being broken due to excessive compression amount. The control unit can adjust the lifting drive 2.11 in real time during the production process, so as to change the distance between the smoke deflector roller 2.1 and the transfer wheel 1.4 in real time and dynamically adjust the compression amount of the base rod 5. By using the base rod 5 compression amount adjusting device provided by the present invention, the extrusion of the smoke deflector roller 2.1 and the transfer wheel 1.4 on the base rod 5 can be kept within a suitable range, and the rejection rate can be reduced.

[0048] On the basis of the above technical solution, the smoke deflector assembly 2 provided by the present invention includes a slide rail 2.10. The support plate 2.7 is installed on the wall panel 1.1. The slide rail 2.10 is used to guide the moving direction of the support plate 2.7. By providing guidance to the support plate 2.7 through the slide rail 2.10, the support plate 2.7 is kept moving vertically to prevent the support plate 2.7 from deflecting laterally. Since the slide rail 2.10 provides guidance to the support plate 2.7, only one lifting drive 2.11 can be set to achieve the distance adjustment. In addition to setting the slide rail 2.10 to provide guidance, two or more lifting drives 2.11 can be set to drive synchronously to replace it.

[0049] In one embodiment, in combination with Figure 6As shown, an installation groove 2.21 for placing the starting rail 2.2 is provided on the outer periphery of the smoke deflector roller 2.1. The installation groove 2.21 is a long groove, and the length extension direction of the installation groove 2.21 is parallel to the axis of the smoke deflector roller 2.1. The installation groove 2.21 is recessed along the radial direction of the smoke deflector roller 2.1. The starting rail 2.2 is locked and installed in the installation groove 2.21 of the smoke deflector roller 2.1 through a set screw 2.13. The length direction of the set screw 2.13 is perpendicular to the surface of the starting rail 2.2. The set screw 2.13 is threadedly installed on the smoke deflector roller 2.1, and one end of the set screw 2.13 contacts the surface of the starting rail 2.2 to form a pressing force on the starting rail 2.2, thereby fixing the starting rail 2.2 on the smoke deflector roller 2.1. When the set screw 2.13 is loosened, the starting rail 2.2 can change the height protruding from the outer surface of the smoke deflector roller 2.1. After the height of the starting rail 2.2 protruding from the smoke deflector roller 2.1 is determined, the set screw 2.13 is re-pressed against the starting rail 2.2 to achieve locking. Each starting rail 2.2 of the present invention can independently adjust the height protruding from the smoke deflector roller 2.1.

[0050] In one embodiment, in combination with Figure 1 As shown, the smoke deflector assembly 2 includes a displacement sensor 2.4. The displacement sensor 2.4 can be installed on the support plate 2.7 or the wall panel 1.1. The displacement sensor 2.4 is used to detect the height of the smoke deflector roller 2.1, and the displacement sensor 2.4 can send a signal to the control unit to feedback the height of the smoke deflector roller 2.1, providing a basis for the adjustment of the smoke deflector roller 2.1. After the zero position of the displacement sensor 2.4 is corrected by combining with the support plate 2.7, the distance between the lower surface of the smoke deflector roller 2.1 and the upper surface of the transfer wheel 1.4 is judged.

[0051] In combination with Figure 5As shown in the figure, the drum wheel assembly 1 includes a transmission shaft 1.2, a drum wheel flange 1.3, an air chamber 1.5, a drum wheel bearing seat 1.6, and a gas distribution seat 1.7; the drum wheel bearing seat 1.6 is installed on the wall panel 1.1, and the drum wheel bearing seat 1.6 plays a supporting role. The transmission shaft 1.2 is installed on the drum wheel bearing seat 1.6 through a bearing. The transmission shaft 1.2 can rotate relative to the drum wheel bearing seat 1.6, and the axis of rotation is the axis of the transmission shaft 1.2. The gas distribution seat 1.7 is installed on the drum wheel bearing seat 1.6 through the drum wheel flange 1.3, and the connection is achieved through the drum wheel flange 1.3; the gas distribution seat 1.7 is installed inside the transfer wheel 1.4, and the air chamber 1.5 is used to generate negative pressure for the gas distribution seat 1.7, so that the transfer wheel 1.4 adsorbs the base rod 5. The gas distribution seat 1.7 is installed on the air chamber 1.5 and is connected in cooperation with the bearing seat 1.6. The negative pressure groove on the circumference of the gas distribution seat 1.6 can control the negative pressure of the transfer wheel 1.4 hub to adsorb the cigarette. The bearing seat 1.6 is internally lined with a sleeve bearing, and the transmission shaft 1.2 is installed at the center. The transmission shaft 1.2 can be driven to rotate by external transmission or direct drive by a motor. The transmission shaft 1.2 is fixedly connected to the flange 1.3 and the transfer wheel 1.4, so that the transfer wheel 1.4 rotates continuously, and then under the action of negative pressure on the transfer wheel 1.4 hub, the cigarette is transported in a circular motion.

[0052] Combined Figure 5 As shown in the figure, the cigarette pushing component 2 includes a first cigarette pushing bearing seat 2.5, a second cigarette pushing bearing seat 2.6, a cigarette pushing flange 2.8, a coupling 2.12, and a stop block 2.14; the second cigarette pushing bearing seat 2.6 is installed on the wall panel 1.1. The first cigarette pushing bearing seat 2.5 and the second cigarette pushing bearing seat 2.6 are two relatively independent structures. The first cigarette pushing bearing seat 2.5 is installed on the second cigarette pushing bearing seat 2.6, which is convenient for installation. The drive shaft 2.3 is installed on the first cigarette pushing bearing seat 2.5 and the second cigarette pushing bearing seat 2.6 through bearings, and the drive shaft 2.3 is supported by the first cigarette pushing bearing seat 2.5 and the second cigarette pushing bearing seat 2.6 respectively. The rolling driver 2.9 is installed on the support plate 2.7 through the cigarette pushing flange 2.8, and the rolling driver 2.9 can adopt a servo motor. The coupling 2.12 is used to connect the drive shaft 2.3 and the rolling driver 2.9. The stop block 2.14 is used to change the axial position on the drive shaft 2.3 to axially position the cigarette pushing roller 2.1. A stop block 2.14 is installed at each axial end of the drive shaft 2.3. The cigarette pushing roller 2.1 is installed on the stop block 2.14 through a pin shaft. Changing the axial position of the stop block 2.14 can adjust the axial position of the cigarette pushing roller 2.1, and the axial position of the cigarette pushing roller 2.1 is limited by the stop block 2.14.

[0053] Based on any of the above technical solutions and their combinations, the base rod compression amount adjusting device of the present invention further includes a detection module 4. The detection module 4 includes a bracket 4.1, a first adjusting block 4.2, a second adjusting block 4.3, and a detector 4.4. One end of the bracket 4.1 is fixedly arranged. The first adjusting block 4.2 can move relative to the bracket 4.1 and adjust the angle. The second adjusting block 4.3 can move relative to the first adjusting block 4.2 and adjust the angle. The detector 4.4 is installed on the second adjusting block 4.3, and the detector 4.4 can move relative to the second adjusting block 4.3 and adjust the angle. The detector 4.4 is used to detect the rupture of the base rod 5 during the self-rotation process with the central axis of the base rod 5 stationary.

[0054] In a specific embodiment, the bracket 4.1 is of a cylindrical structure. One end of the bracket 4.1 is fixed on the wall panel 1.1 or the air chamber 1.5, and the other end is matched with the hole of the first adjusting block 4.2 through a cylindrical surface. The first adjusting block 4.2 can adjust the axial position and the radial angular position on the cylindrical surface of the bracket 4.1, and the first adjusting block 4.2 is locked on the bracket 4.1 through a locking screw. The other end of the first adjusting block 4.2 is a shaft, and the hole of the second adjusting block 4.3 can be connected to the shaft of the first adjusting block 4.2. The axial and radial positions of the shaft and the hole can be changed and fixed with locking screws. Similarly, one end of the detector 4.4 is a hole that can be connected to the shaft at the other end of the second adjusting block 4.3 to adjust the axial and radial positions and fixed with locking screws. The other end of the detector 4.4 is cylindrical, with an imaging unit in the middle and a synchronous strobe light arranged at the outer circumferential end. Through the bracket 4.1, the first adjusting block 4.2, and the second adjusting block 4.3, the positions in the depth direction and the vertical direction can be changed, and the base rod 5 that does not move at the center and rotates can be subjected to on-line appearance detection at the desired position and angle. The base rod 5 is driven to rotate by the cigarette pushing roller 2.1 and the transfer wheel 1.4. The base rod 5 rolls relative to the outer surface of the cigarette pushing roller 2.1 and the outer surface of the transfer wheel 1.4 respectively. By controlling the rotation speeds of the cigarette pushing roller 2.1 and the transfer wheel 1.4, the base rod 5 makes a self-rotation movement with the spatial position of the central axis unchanged, and the position of the base rod 5 relative to the detector 4.4 remains unchanged for detection. The detection result of the detector 4.4 serves as the basis for judging the quality of the base rod and as the basis for adjusting the distance between the cigarette pushing roller 2.1 and the transfer wheel 1.4.

[0055] Furthermore, two sets of detection modules 4 are provided to respectively detect whether there is damage to the base rod 5 squeezed by the transfer wheel 1.4 and the cigarette pushing roller 2.1 from both sides. Figure 4 As shown in the figure, the detection modules 4 on the left and right sides detect the breakage condition of the cigarette at different angles and positions simultaneously. The detection accuracy of this method is higher than that of the traditional method, and when the breakage rate of a group of base rods is relatively high, a signal can be sent in real time and the height of the cigarette pushing roller 2.1 can be adjusted by the control unit.

[0056] The base rod compression amount adjusting device of the present invention further includes a laser drilling module 3. The laser drilling module 3 includes a drilling nozzle 3.1 and a laser channel 3.2. The drilling nozzle 3.1 faces the base rod 5 and is used to drill the base rod 5 that rolls between the transfer wheel 1.4 and the smoke deflecting roller 2.1. The transfer wheel 1.4 and the smoke deflecting roller 2.1 rotate simultaneously, and their speeds can be neutralized and offset, so that the base rod 5 can perform a self-rotation motion with a constant center on the common tangent of the transfer wheel 1.4 and the smoke deflecting roller 2.1. Since the center of the base rod 5 remains unchanged, the distance from the drilling nozzle 3.1 to the surface of the base rod 5 remains unchanged, and thus the focal length remains unchanged. There is a laser channel 3.2 on the left side of the base rod 5 to transmit a laser beam to the drilling nozzle 3.1, and then the drilling nozzle 3.1 focuses to perform an on-line drilling function on the rotating base rod 5.

[0057] To complete the drilling function, tangential frictional forces must exist above and below the base rod. Therefore, the gap between the smoke deflecting roller 2.1 and the transfer wheel 1.4 must be smaller than the diameter of the base rod, so that a compression amount is formed on the upper and lower sides of the base rod 5. However, since the sealed end of such a cigarette has a film, when compressed and deformed, it is extremely easy to cause the film to break between the film and the paper tube, thus forming a break, and the particles inside the cigarette leak out and remain on the hub, further affecting the compression amount of the cigarette. The cigarette particles stick to the cigarette and form waste cigarettes in the next inspection process, increasing the rejection rate. The height of the traditional smoke deflecting roller cannot be adjusted online, and thus the distance between the surfaces of the transfer wheel and the smoke deflecting roller cannot be adjusted. When manually adjusting the compression amount after each shutdown, it takes more than one hour, and it is not necessarily adjusted to a reasonable position, and the adjustment range is limited. For the traditional smoke deflecting roller, since the starting rails of multiple protrusions on the wheel are welded to the smoke deflecting roller wheel, the height of the protruding starting rails cannot be adjusted, and thus the height of the protrusions is not in the best reasonable position, and its adaptability to different materials is not high. The original appearance detection method cannot effectively detect cigarettes with tiny breaks, and increasing the resolution will also increase the generation of waste products.

[0058] The base rod compression amount adjusting device of the present invention can adjust the distance between the smoke deflecting roller 2.1 and the transfer wheel 1.4, so as to adjust the compression amount. It can change the height of the starting rail 2.2 protruding from the outer surface of the smoke deflecting roller 2.1, adjust the compression amount relative to the base rod 5, and can finely adjust the axial inclination angle, with higher adaptability to different materials. This device is designed with a detection module 4 to realize the on-line detection function, which can detect in real time during the drilling process, and the detection module 4 performs detection in the state where the base rod is compressed, and the detection accuracy is higher than that of the traditional method. When changing the specifications of cigarette accessories, this device can quickly adjust online and quickly obtain the optimal solution of the cigarette compression amount, and can detect even avoid broken cigarettes more accurately in a larger range, and perform precise rejection downstream, reducing the rejection rate.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
