Description

TECHNICAL FIELD

[0001] The patent relates to the technical field of tobacco filtration, and particularly relates to a non-contact air supply type blasting bead implanting device. BACKGROUND

[0002] The current air supply mode of the blasting bead implanting device is a contact air supply mode based on surface sealing. The implanting mechanism of the device is composed of an implanting disc, a base plate, a friction ring, an air supply ring, a speed reducer and a driving motor. The friction ring and the base plate have air holes corresponding to the blasting bead positions of the implanting disc. The friction ring directly contacts the air supply disc to form a sealed cavity through surface sealing. When the equipment is running, the sealed cavity is given a negative pressure, and the friction ring, the base plate and the implanting disc rotate relative to the air supply disc. The implanting disc rotates to the expected position through the formed negative pressure to adsorb the blasting bead and complete the blanking.

[0003] The contact air supply structure of the traditional device relies on the surface sealing of the friction ring and the air supply disc to form a negative pressure cavity. The core problem is derived from the design principle of “contact friction”. The friction ring and the air supply disc have a severe surface wear during high-speed relative rotation (matching the cigarette production speed), and the average service life is only 3-5 months. The spare parts need to be frequently replaced, which increases the equipment maintenance cost and downtime. Secondly, the break-in time is long, and the production efficiency is low. In order to ensure the sealing effect, a thickness allowance of 0.1-0.2 mm needs to be reserved when the new friction ring is processed. After installation, the break-in needs to be forced for 8 hours (one production shift), during which the equipment cannot produce normally, which seriously affects the production progress. Finally, the compatibility is poor, and the replacement is difficult. The sizes and adsorption parameters of different types of blasting beads are different. When the production type is changed, the implanting disc, the base plate and the friction ring need to be replaced simultaneously, and the replacement needs to be re-broken-in after replacement. The replacement process takes more than 4 hours, which is difficult to adapt to the production demand of multiple varieties and small batches. SUMMARY

[0004] The purpose of the patent is to improve the efficiency of implanting blasting beads into the filter section of a tobacco product. To solve the technical problem: The patent provides a non-contact air supply type blasting bead implanting device, which comprises an air supply disc, a bead implanting disc and a negative pressure source. The bead implanting disc comprises radially arranged air holes for adsorbing blasting beads. The air supply disc comprises a negative pressure part located at the outer periphery, which communicates with the air holes to enable the air holes to adsorb blasting beads. The negative pressure source is connected to the air supply disc and provides negative pressure in the negative pressure part. The outer side wall of the air supply disc and the inner side wall of the bead implanting disc are gap-fitted and form a fitting gap, and the fitting gap has a gap airflow.

[0005] Further, the width of the fitting gap in the radial direction is 0.01mm-0.05mm, 0.05mm-0.10mm or 0.10mm-0.30mm.

[0006] Furthermore, the gauge pressure within the negative pressure section relative to standard atmospheric pressure is not less than -0.35 to -0.48 bar, -0.48 to -0.60 bar, or -0.60 to -1.00 bar.

[0007] Furthermore, the negative pressure fluctuation is no greater than 0.10 bar, 0.05 bar, or 0.01 bar; the negative pressure fluctuation is the gauge pressure fluctuation within the negative pressure section relative to standard atmospheric pressure caused by the interstitial airflow.

[0008] Furthermore, the negative pressure section is opened along the circumference of the air distribution plate, and the maximum circumferential length of the negative pressure section does not exceed 1 / 4, 1 / 3 or 1 / 2 of the outer circumference of the air distribution plate.

[0009] Furthermore, it includes a rotating mechanism for driving the bead-planting disc to rotate, and the rotating mechanism is fixedly connected to the air distribution disc.

[0010] Furthermore, when the bead-planting disc rotates, the speed of the bead-planting disc is not less than 150 m / min, 150 m / min, or 300 m / min.

[0011] Furthermore, the bead-planting tray also includes a central hole, and the air distribution plate also includes a central hole. The bead-planting tray has a first protrusion extending towards the air distribution plate near the outer periphery of the central hole; the first protrusion is inserted into the central hole of the air distribution plate; the outer side wall of the first protrusion forms a clearance fit with the inner side wall of the central hole of the air distribution plate; the first protrusion is connected to the rotating mechanism.

[0012] Furthermore, the non-contact gas distribution method bead implantation device also includes a bead implantation disc gasket, which is disposed on the surface of the bead implantation disc away from the gas distribution disc, and is used to seal the hole in the bead implantation disc.

[0013] Furthermore, the valve plate has a second extension near the outer periphery of the central hole of the valve plate, extending in the direction of the rotating mechanism; the second extension is connected to the rotating mechanism.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This patented capsule implantation device generates almost no friction between the gas distribution plate and the capsule implantation plate, making it a highly efficient capsule implantation device that improves the efficiency of capsule implantation into the filter section of tobacco products. When the negative pressure in the negative pressure section is appropriate and the gap between the gas distribution plate and the capsule implantation plate is appropriate, the relative rotational motion of the gap-fitted gas distribution plate and the capsule implantation plate generates almost no friction, resulting in a very small gap airflow. The negative pressure formed in the air holes is sufficient to meet the capsule delivery requirements. At the same time, the non-strictly sealed transmission structure of sealing / transmission components such as frictionless rings and sealing rings avoids the problems caused by contact friction during the relative rotational motion of the gas distribution plate and the capsule implantation plate in the prior art, including: component wear, break-in time, and difficulty in changing models.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] like Figure 1 , 2 This patent provides an embodiment of a non-contact gas distribution method for implanting explosive beads, including a gas distribution plate 200, a bead implantation plate 100 and a negative pressure source (not shown in the figure); the bead implantation plate 100 includes radially opened air holes 110, which are used to adsorb explosive beads.

[0028] The valve plate 200 includes a negative pressure section 210 located on the outer periphery; a negative pressure source is connected to the valve plate 200 and provides negative pressure within the negative pressure section 210.

[0029] The working principle of the vent 110 and the negative pressure section 210 is basically the same as that of the bead-planting mechanism in the prior art. That is, when the vent 110 is directly facing the negative pressure section 210, there is also a negative pressure inside the vent 110, which adsorbs the popping beads and makes it difficult for the popping beads to detach from the vent 110. When the bead-planting plate 100 rotates relative to the air distribution plate 200 so that the vent 110 is no longer directly facing the negative pressure section 210, there is no longer a negative pressure inside the vent 110, and the popping beads easily detach from the vent 110.

[0030] Optionally, the air distribution plate 200 may also include a positive pressure section for providing positive pressure to the air hole 110 to remove the burst bead from the air hole 110.

[0031] The outer wall of the air distribution plate 200 and the inner wall of the bead planting plate 100 are fitted together to form a fitting gap 211, and there is a gap airflow in the fitting gap 211.

[0032] The applicant discovered that when the negative pressure within the negative pressure section 210 is appropriate and the gap between the air distribution plate 200 and the bead-planting plate 100 is suitable, the relative rotational motion of the air distribution plate 200 and the bead-planting plate 100 with the gap fit generates almost no friction, resulting in a very small gap airflow. The negative pressure formed in the air hole 110 is sufficient to meet the conveying requirements of the popping beads. Simultaneously, the non-strictly sealed transmission structure with frictionless rings, sealing rings, and other sealing / transmission components can avoid the problems caused by contact friction during the relative rotational motion of the air distribution plate 200 and the bead-planting plate 100 in the prior art, including: component wear, break-in time, and difficulty in changing models.

[0033] The radial width of the mating clearance is 0.01mm~0.05mm, 0.05mm~0.10mm, or 0.10mm~0.30mm. Preferably, it is 0.05mm~0.10mm. If this width is too large, the mating clearance will be too large, resulting in excessive airflow and negative pressure loss, leading to unstable adsorption of the beads. If the clearance is too small, the bead-planting disc 100 and the air distribution disc 200 will be difficult to assemble, failing to achieve the technical effect of shortening the break-in time and changeover time. It will also lead to unplanned wear and leakage due to machining errors in the bead-planting disc 100 or the air distribution disc 200, and will result in excessively high component processing costs.

[0034] The gauge pressure within the negative pressure section 210 relative to standard atmospheric pressure is not less than -0.35 to -0.48 bar, -0.48 to -0.60 bar, or -0.60 to -1.00 bar. Preferably, it is -0.35 to -0.60 bar.

[0035] The gauge pressure in the negative pressure section 210 relative to standard atmospheric pressure is related to the speed of the bead reel 100. For example, based on the speed of the bead reel 100, the gauge pressure in the negative pressure section 210 relative to standard atmospheric pressure is approximately -0.35 bar at a production speed of 200 m / min, approximately -0.48 bar at a production speed of 250 m / min, and approximately -0.55 to -0.60 bar at a production speed of 300 m / min.

[0036] Furthermore, temperatures below -1.00 bar may cause the capsules to deform, while temperatures above -0.35 bar may result in insufficient adsorption, leading to capsule flying at high speeds. It is particularly important to note that the optimal energy efficiency ratio is achieved in the -0.48 to -0.60 bar range.

[0037] For example, when the clearance between the air distribution plate and the planter plate is set to 15 to 24 micrometers, the tolerance on one side is 7 to 12 micrometers. During the experimental debugging process, it was found that under this condition, the negative pressure value of the planter plate was in the range of (0.2~0.3) kPa, resulting in poor adsorption of the popping beads and causing the beads to fly away. When the tolerance was improved to 9 to 15 micrometers and the tolerance on one side was adjusted to 5 to 8 micrometers, the air pressure was significantly improved and stabilized in the range of (0.4~0.5) kPa. The popping beads were firmly adsorbed, and the flying beads phenomenon did not occur, thus meeting the design requirements of sufficient negative pressure and good process performance of the mechanism.

[0038] In one embodiment, the vehicle speed is 300 m / min and the adsorption pressure is -0.50 bar. The burst bead implantation device uses a negative pressure adsorption method to transfer the burst beads. The burst bead picking plate has air holes 110 evenly distributed at angles to adsorb the burst beads one by one, and the burst beads are driven to rotate by a servo motor. The force analysis of the burst beads shows that the burst beads are subjected to gravity G, centripetal force F, negative pressure Fnegative, and air resistance is negligible.

[0039] At this point, according to the pressure calculation formula F=ps, where p is the pressure and s is the area of ​​contact. Based on the negative pressure gauge data, p=0.05MPa, s=3.14 1 1mm 2

[0040] Fnegative = 0.05 10 6 3.14 10 -6 =157 10 -3 N

[0041] According to the centripetal force calculation formula, substituting the vehicle speed v = 300 m / min = 5 m / s, the radius of rotation r = 0.112 m, and m = 0.023g = 23, we get... 10 -6 kg yields: F direction = 23 10 -6 52 / 0.112=5 10 -3 N G=0.23 10 -3 N Ultimately, it can be calculated that Fnegative > Fdirective + G, and Fsum = 151.7. 10 -3 N < burst pressure 16.5N. From Fnegative > Fpositive + G, we can conclude that the burst beads are firmly adsorbed by the negative pressure on the plant plate, preventing any flying beads; from Ftotal = 151.7 10 -3 Since N < burst pressure 16.5N, there is no risk of the bursting bead rupturing, and the negative pressure adsorption structure meets the usage requirements.

[0042] Negative pressure fluctuations are no greater than 0.10 bar, 0.05 bar, or 0.01 bar. Negative pressure fluctuations are the gauge pressure fluctuations within the negative pressure section relative to standard atmospheric pressure caused by interstitial airflow. Negative pressure fluctuations directly affect adsorption stability and also indicate that the size of the interstitial airflow is within an appropriate range. Excessive negative pressure fluctuations indicate that the interstitial airflow is too large and unstable, suggesting that the mating clearance 211 is too large.

[0043] Preferably, the negative pressure section 210 is opened along the circumference of the air distribution plate 200, and the maximum circumferential length of the negative pressure section 210 does not exceed 1 / 4, 1 / 3 or 1 / 2 of the outer circumference of the air distribution plate 200.

[0044] Preferably, the non-contact gas distribution method for implanting beads further includes a rotating mechanism for driving the bead-implanting disc 100 to rotate, and the rotating mechanism is fixedly connected to the gas distribution disc 200. The rotating mechanism includes a reducer 300 and a power source 400. In the prior art, a transmission device is usually required to transmit the power of the rotating mechanism to the bead-implanting disc.

[0045] Since there is almost no friction between the bead-planting disc 100 and the air distribution disc 200, the rotating mechanism can drive the bead-planting disc 100 to rotate with high precision while being fixedly connected to the air distribution disc 200. At the same time, it saves transmission steps, has higher transmission efficiency, lower material costs, more reliable transmission, and a more compact machine structure.

[0046] For example, the reducer model is FAD090 system. When the bead-planting disc rotates, the speed of the bead-planting disc 100 is not less than 150 m / min, 200 m / min, or 300 m / min. In the embodiments of this patent, the negative pressure adsorption force provided by the bead-planting disc 100 is sufficient to meet the high-speed requirements.

[0047] Specifically, the bead-planting tray 100 also includes a bead-planting tray central hole 120, and the air distribution tray 200 also includes an air distribution tray central hole 220. The bead-planting tray 100 has a first protrusion 130 extending into the air distribution tray 200 near the outer periphery of the bead-planting tray central hole 129. The first protrusion 130 is inserted into the air distribution tray central hole 220, and the outer wall of the first protrusion 130 forms a clearance fit with the air distribution tray central hole 220. The first protrusion 130 is connected to the rotating mechanism. This connection structure is relatively compact and reliable.

[0048] Preferably, it also includes a bead-planting tray gasket 500, which is disposed on the surface of the bead-planting tray 100 away from the air distribution plate 200. The bead-planting tray gasket 500 is used to seal the first central hole to prevent foreign objects from entering.

[0049] Specifically, the valve plate 200 has a second extension 230 extending towards the rotating mechanism near the outer periphery of the valve plate central hole 220; the second extension 230 is connected to the rotating mechanism. This connection structure is relatively compact and reliable.

[0050] Industrial applicability

[0051] like Figure 3 As shown, the non-contact gas distribution method capsule implantation device 1000 of this patent is an important component of the capsule mouthpiece production system. For example, a capsule mouthpiece production system includes the non-contact gas distribution method capsule implantation device 1000, a capsule supply device 1100, a filament supply device 2000, a mouthpiece forming device 3000, and a mouthpiece conveying device 4000. When this system produces capsule mouthpieces, the filament supply device 2000 supplies filament to the mouthpiece forming device 3000, while the capsule supply device 1100 supplies capsules to the capsule implantation device 1000. The capsule implantation device 1000 implants the capsules into the filament during the forming process. Through the above process, a mouthpiece containing capsules is formed at the outlet of the mouthpiece forming device 3000 and then conveyed to the subsequent station by the mouthpiece conveying device 4000.

[0052] In summary, this patent, referencing the non-contact gas distribution structure of a smoke distribution wheel, designs a micro-gap non-contact fit between the bead-planting tray and the gas distribution tray. It utilizes negative pressure airflow to stably adsorb the burst beads, avoiding wear and contamination caused by mechanical friction. By optimizing the gas path layout and sealing structure, it improves negative pressure stability and response speed, ensuring precise and controllable adsorption and release of the burst beads. This design not only extends the equipment's service life but also reduces maintenance frequency and operating noise, achieving efficient, clean, and stable continuous production, laying the technical foundation for subsequent compatible switching between multiple burst bead specifications.
