Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco equipment, in particular to a bead implanting mechanism with a frictionless negative pressure structure. Background Art
[0002] Most of the existing technologies use the single-bead straight-through molding process with double-disc synchronous belt drive manufactured by South Korea's Zhengguang Machinery. The speed cannot exceed 100m / min, and it is prone to problems such as broken beads in the hopper, flying beads, insufficient beads, and large phase deviation. Or the equipment produced by Germany's Hauni has a speed of 300m / min, but it is expensive and needs to be used in conjunction with the molding machine equipment produced by Hauni. It also has relatively high requirements for the raw material bead blasting. Most domestic bead blasting equipment is between 150m-200m / min, and the equipment structure is complex and the production performance stability is poor. Utility Model Content
[0003] In view of the above problems, a bead implanting mechanism with a frictionless negative pressure structure is now provided, aiming to solve the problems existing in the prior art.
[0004] The specific technical solutions are as follows:
[0005] A bead planting mechanism with a frictionless negative pressure structure comprises an air distribution disk and a bead planting disk, the air distribution disk is a cylindrical structure, the bead planting disk is a cylindrical structure closed at one end, and the bead planting disk can be sleeved on the air distribution disk, a negative pressure cavity is opened on the outer ring side wall of the air distribution disk, a negative pressure port connected with the negative pressure cavity is opened on the end face of the air distribution disk facing away from the bead planting disk, a positive pressure channel is also opened on the air distribution disk, a first opening of the positive pressure channel is located on the outer ring side wall of the air distribution disk, a second opening of the positive pressure channel extends to the end face of the air distribution disk facing away from the bead planting, an annular extension body is extended outwardly from the outer ring side wall of the bead planting disk, adsorption channels are uniformly and radially opened on the annular extension body, when the bead planting disk is sleeved on the air distribution disk, the adsorption channel on the same side as the negative pressure cavity is connected with the negative pressure cavity, and the adsorption channel facing the positive pressure channel is connected with the positive pressure channel.
[0006] The above-mentioned bead planting mechanism of the frictionless negative pressure structure also has the following characteristics: the outer ring side wall of the gas distribution disk is also provided with two annular grooves, and sealing rings are arranged in the annular grooves. The two annular grooves are respectively arranged on the front and rear sides of the negative pressure cavity and the first opening of the positive pressure channel. When the bead planting disk is mounted on the gas distribution disk, the inner ring side wall of the bead planting disk, the two sealing rings and the outer ring side wall of the gas distribution disk jointly form a sealed cavity.
[0007] The beneficial effects of the above solution are as follows: the two sealing rings are used to enhance the sealing effect and prevent the negative pressure in the negative pressure cavity from decreasing.
[0008] The bead implanting mechanism of the frictionless negative pressure structure mentioned above also has the characteristic that the length of the negative pressure chamber does not exceed half of the circumference of the outer ring of the gas distribution disk.
[0009] The beneficial effect of the above scheme is that the negative pressure chamber only needs to maintain a pressure in the sealed cavity that is sufficient to adsorb the explosive beads to the adsorption channel opening. An excessively long negative pressure chamber will lead to a decrease in negative pressure.
[0010] The above-mentioned frictionless negative pressure structure bead planting mechanism also has the following characteristics: the number of the negative pressure ports is three, the three negative pressure ports are evenly distributed on the end surface of the air distribution disk facing away from the bead planting disk, and the three negative pressure ports are all connected to the negative pressure cavity, and the three negative pressure ports are all connected to an external negative pressure device.
[0011] The beneficial effect of the above solution is that the multiple negative pressure ports are connected to the external negative pressure device, so that the negative pressure in the negative pressure cavity is sufficient to adsorb the explosive beads.
[0012] The above-mentioned frictionless negative pressure structure of the bead planting mechanism also has the following feature: an extension connector for connecting to an external driving device is provided on the side of the closed end of the bead planting plate facing the gas distribution plate, and the extension connector extends into the middle channel of the gas distribution plate. When the gas distribution plate is in a fixed state, the bead planting plate can be driven to rotate by an external driving device.
[0013] The beneficial effect of the above scheme is that the power output end of the external driving device passes through the middle channel of the gas distribution disk and is connected to the extended connecting body, so as to drive the bead planting disk to rotate while keeping the gas distribution disk fixed.
[0014] In summary, the beneficial effects of this scheme are:
[0015] In the bead implanting mechanism with a frictionless negative pressure structure provided by the utility model, the bursting beads are adsorbed through the adsorption channel at the edge of the bead implanting plate, and the negative pressure is much greater than the centrifugal force of its operation, ensuring that the bursting beads can be stably adsorbed on the edge of the bead implanting plate, ensuring that the bursting beads will not produce flying beads and broken beads, and when the adsorption channel rotates to face the positive pressure channel, the adsorption force disappears, and the bursting beads are driven to be implanted into the yarn bundle. The bead implanting mechanism with a frictionless negative pressure structure provided by the utility model has the effect of stably implanting the bursting beads into the yarn bundle.

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0023] The present invention will be further described below in conjunction with specific embodiments, but this is not intended to limit the present invention.

Figure 2 For this utility model Figure 1 The enlarged structural diagram at A in the middle, Figure 3 This is a front view structural diagram of the bead implanting mechanism of the frictionless negative pressure structure of the utility model. Figure 4 For this utility model Figure 3 The schematic diagram of the cross-sectional structure in the AA direction is as follows: Figure 1-Figure 4 As shown, the frictionless negative pressure structure bead planting mechanism provided in this embodiment includes an air distribution plate 1 and a bead planting plate 2, the air distribution plate 1 is a cylindrical structure, the bead planting plate 2 is a cylindrical structure closed at one end, and the bead planting plate 2 can be sleeved on the air distribution plate 1, a negative pressure cavity 3 is provided on the outer ring side wall of the air distribution plate 1, a negative pressure port 4 connected to the negative pressure cavity 3 is provided on the end surface of the air distribution plate 1 facing away from the bead planting plate 2, and a positive pressure channel 5 is also provided on the air distribution plate 1, and the first positive pressure channel 5 is provided with a positive pressure port 4 connected to the negative pressure cavity 3. One opening is on the outer ring side wall of the air distribution disk 1, and the second opening of the positive pressure channel 5 extends to the end face of the air distribution disk 1 facing away from the planting beads. The outer ring side wall of the bead planting disk 2 is extended outward to provide an annular extension body 6, and the annular extension body 6 is evenly and radially provided with adsorption channels 7. When the bead planting disk 2 is mounted on the air distribution disk 1, the adsorption channel 7 on the same side as the negative pressure chamber 3 is connected to the negative pressure chamber 3, and the adsorption channel 7 facing the positive pressure channel 5 is connected to the positive pressure channel 5.
[0025] It should be noted that when the bead planting plate 2 is mounted on the gas distribution plate 1, a gap is left between the inner ring side wall of the bead planting plate 2 and the outer ring side wall of the gas distribution plate 1. When the bead planting plate 2 rotates, there is no direct contact between the bead planting plate 2 and the gas distribution plate 1, thereby achieving the effect of reducing friction.
[0026] In the above embodiment, the outer ring side wall of the gas distribution disk 1 is also provided with two annular grooves, and sealing rings 8 are arranged in each of the annular grooves. The two annular grooves are respectively arranged on the front and rear sides of the negative pressure chamber 3 and the first opening of the positive pressure channel 5. When the bead planting plate 2 is mounted on the gas distribution disk 1, the inner ring side wall of the bead planting plate, the two sealing rings 8 and the outer ring side wall of the gas distribution disk 1 jointly form a sealed cavity.
[0027] In the above embodiment, the length of the negative pressure chamber 3 does not exceed half of the circumference of the outer ring of the gas distribution disk 1.
[0028] In the above embodiment, the number of negative pressure ports 4 is three, and the three negative pressure ports 4 are evenly distributed on the end surface of the gas distribution disk 1 facing away from the bead planting disk 2, and the three negative pressure ports 4 are all connected to the negative pressure cavity 3, and the three negative pressure ports 4 are all connected to the external negative pressure device.
[0029] In the above embodiment, an extension connector for connecting to an external driving device is provided on the side of the closed end of the bead planting plate 2 facing the gas distribution plate 1, and the extension connector extends into the middle channel of the gas distribution plate 1. When the gas distribution plate 1 is in a fixed state, the bead planting plate can be driven to rotate by the external driving device.
[0030] Working principle: after the bead taking plate completes the arrangement of the bursting beads, the bursting beads are transferred to the bead planting plate 2. The transfer process is that the bead taking plate throws out the bursting beads through centrifugal force, and the adsorption channel 7 on the edge of the bead planting plate 2 adsorbs the bursting beads when it is aligned with the bursting beads. As the bead planting plate 2 continues to rotate, the adsorption channel 7 adsorbed with the bursting beads rotates to face the positive pressure channel 5, the negative pressure in the adsorption channel 7 decreases, the adsorption force decreases, and the adsorbed bursting beads break away from the filament bundle to complete the bead planting. Moreover, since the bead planting plate 2 is not in direct contact with the gas distribution plate 1, there is no friction between the two when the bead planting plate 2 rotates, which makes the operation of the bead planting plate 2 smoother, improves the performance stability of the equipment and reduces the maintenance frequency.
[0031] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of the present invention specification should be included in the protection scope of the present invention.
