Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing equipment, in particular to a device for uniformly applying particles to a tobacco filter rod. Background Art

[0002] In the tobacco processing industry, currently, composite filter rods containing functional particles are used more and more widely in cigarette products. The particle-containing filter rod is formed by spraying particles on a fiber tow by a device and then rolling. When rolling the particle filter rod, the uniform application of particles is crucial for the product quality of the filter rod. Since the raw materials of various functional particles are different, some are fragile and some are sticky. If the particle application device cannot be well adapted to various particles and the application process is not smooth, it will cause the particles contained in the particle filter rod to be uneven, seriously affecting the product quality. At the same time, it is also necessary to frequently stop the machine to clean the application device or reduce the speed of operation to adapt to different particles, which affects the operation efficiency of the equipment. It can be seen that effectively solving the adaptability of the particle application device to various particles and the uniformity of application plays an important role in the quality of the particle filter rod and the operation efficiency of the equipment.

[0026] The present utility model provides a device 100 for uniformly applying particles to a tobacco filter rod.

[0027] As Figures 1 - 3As shown, in an embodiment of the present utility model, the tobacco filter rod particle uniformly applying device 100 includes a housing 10, a connecting platform 30, and a particle bin 20. The connecting platform 30 is installed on the top of the housing 10, and the particle bin 20 is installed on the top of the connecting platform 30. A buffer channel 31 is provided in the connecting platform 30, and the buffer channel 31 communicates the interior of the housing 10 with the particle bin 20. A metering drum 40 is provided in the housing 10. After being buffered by the buffer channel 31, the particles fall into the grooves on the surface of the metering drum 40. The particles fall when the metering drum 40 rotates to a preset position. A blowing pipe 60 is provided on one side of the metering drum 40 to blow off the particles adhering to the metering drum 40.

[0028] In this embodiment, a gate plate 50 is provided on the connecting platform 30. The gate plate 50 separates the discharge port of the particle bin 20 from the buffer channel 31. An air cylinder 51 is provided outside the connecting platform 30, and the air cylinder 51 is connected to the gate plate 50. The control of the gate plate 50 is driven by the solenoid valve to control the air cylinder 51, and is synchronously controlled with the start and stop of the equipment for opening the gate plate 50. Among them, the particle bin 20 is in an overall shape of a bamboo hat with a wider top and a narrower bottom. The particle bin 20 and the gate plate 50 are made of smooth-surface metal plates with a thickness of 1.0 mm. The volume of the bin is about 0.3 cubic meters. The width of the bottom discharge port of the particle bin 20 is 120 mm, and the length is 300 mm. The length and width of the gate plate 50 are the same as those of the discharge port of the particle bin 20.

[0029] The connecting platform 30 is made of smooth-surface metal plates with a thickness of 1.0 mm. Among them, the buffer channel 31 is wavy, the width of the channel is 120 mm, and the length is 300 mm. Two pneumatic vibrators 52 are installed on both sides of the outer wall of the connecting platform 30 to ensure that the particles can fall from the buffer channel 31 into the metering drum 40.

[0030] In an embodiment of the present utility model, a boss 11 is provided in the housing 10. The boss 11 fits the surface of the metering drum 40. A plastic cover plate 12 is provided on the boss 11. The plastic cover plate 12 fits the surface of the metering drum 40 and covers a quarter of the outer arc of the metering drum 40.

[0031] In this embodiment, a driving motor 41 is provided outside the housing 10. The driving motor 41 is connected to the metering drum 40 and is used to drive the metering drum 40 to rotate. The driving motor 41 is an adjustable-speed servo motor; the metering drum 40 is made of a metal material, with a drum diameter of 150 mm, a length of 300 mm, and 100 groove positions evenly distributed on the drum surface. Each groove has a width of 5 mm and a depth of 2 mm; the plastic cover plate 12 is made of PVC plastic, with a thickness of 0.5 mm, a length of 80 mm, and a width of 300 mm.

[0032] It can be understood that the plastic cover plate 12 covers a quarter of the outer arc of the metering drum 40, which can ensure that the particles do not fall prematurely when the metering drum 40 rotates. When the metering drum 40 rotates a quarter of a circle, the grooves on the surface of the metering drum 40 face downward, and the particles fall. The amount of particles falling into each groove is the same, realizing uniform application. When it is necessary to change the amount of particle application, it can be adjusted by changing the speed of the metering drum 40.

[0033] In an embodiment of the present invention, the air blowing pipe 60 is provided on the side where the plastic cover plate 12 is provided. A number of air blowing holes 62 are opened on the air blowing pipe 60. An air pressure regulating valve 61 is provided outside the housing 10. The air pressure regulating valve 61 is connected to the air blowing pipe 62 and is used to regulate the air pressure.

[0034] In the embodiment, the air blowing pipe 60 has a diameter of 8 mm. There is a row of straight and dense small holes on the air blowing pipe 60, with a hole diameter of 1.5 mm. The air blowing pipe 60 is connected to the equipment air source distribution valve through an air pipe, and cooperates with the pressure regulating valve 61 to regulate the pressure. The air blowing position is aligned with the outlet at the end of the plastic cover plate 12. The angle of the air blowing holes 62 is inclined downward to ensure that the particles adhering to the grooves of the metering drum 40 can be effectively blown off after leaving the plastic cover plate 12. The air volume of the air blowing pipe 60 is controlled by the regulating valve.

[0035] A tow plate 70 is provided at the bottom of the housing 10. The tow plate 70 gradually narrows with the tow 80 and is triangular in shape. Baffles 71 are provided on both sides of the tow plate 80. The height of the baffles 71 is 20 mm. The function of the tow plate 70 is to prevent the particles from penetrating through the tow 80 and falling off, which affects the amount of particle application.

[0036] Working principle: When the device is running, the cylinder 51 is automatically opened, and the gate 50 between the granular material bin 20 and the buffer channel 31 is opened. Granules fall freely from the discharge port of the granular material bin 20 into the buffer channel 31. The buffer channel 31 is designed in a wavy shape to slow down the crushing of granules caused by weight extrusion. The pneumatic vibrator 52 ensures that the granules fall into the grooves of the metering roller 40. The function of the grooves is to control the application amount of granules. The granules fall into and fill the grooves. The plastic cover plate 12 covers about one-fourth of the arc outside the metering drum 40 to ensure that the granules do not fall prematurely when the metering drum 40 rotates. When the metering drum 40 rotates one-fourth of a turn, the grooves face downward and the granules fall. At the same time, the air blown out by the air blowing pipe 60 effectively blows off the granules adhering to the grooves of the metering drum 40. The granules are blown onto the unfolded tow 80. The tow support plate 70 at the bottom of the tow 80 can prevent the granules from penetrating the tow 80 and falling off, which affects the application amount of granules.

[0037] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
