[0002] The window series filter rods have a crystal-clear appearance. The cigarettes rolled with them have a novel and unique appearance, with strong visual impact and rich smoking tastes. The series products have a high recognition in the consumer market. The window series filter rods are a new type of special composite rod. When compounding, a certain gap is left between the two base rods to form a cavity, and then particles are filled into the gap. Finally, it is wrapped and compounded with transparent forming paper to achieve a visible effect.

[0003] In order to achieve quantitative output of particles, a new quantitative discharging structure is needed. Content of the Utility Model

[0004] Aiming at the above problems, a quantitative discharging structure of a filter rod particle adding device is provided, aiming to solve the problems existing in the prior art.

[0005] The specific technical solutions are as follows:

[0006] A quantitative discharging structure of a filter rod particle adding device includes a frame, a material bin, a feeding assembly, a quantitative assembly and a discharging assembly. The material bin, the feeding assembly, the quantitative assembly and the discharging assembly are all arranged on the frame. The feeding assembly is communicated with the material bin. The output end of the feeding assembly is communicated with the feeding port of the quantitative assembly. The output end of the quantitative assembly is correspondingly communicated with the discharging assembly. A transmission assembly is arranged directly below the discharging assembly. The transmission assembly is used to convey the spaced filter rods forward. When the discharging assembly is opened, the particles in the discharging assembly just enter the gap between the filter rods. The quantitative assembly is used to receive the particle material output by the feeding assembly and periodically and quantitatively output the material into the discharging assembly to fill the particle material into the gap between the filter rods.

[0007] The quantitative discharging structure of the above-mentioned filter rod particle adding device further has the following characteristics. The quantitative assembly includes a quantitative disk, a transmission shaft, a cover plate, a proximity sensor, and a valve opening and closing part. The top of the quantitative disk is open, and the cover plate covers the opening of the quantitative disk to seal the opening. An inlet port is provided at the top of the cover plate, and the feeding assembly is communicated with the inlet port. The cover plate is fixedly connected to the feeding assembly. A through hole is provided at the center of the bottom of the quantitative disk. The lower end of the transmission shaft is in transmission connection with the driving mechanism in the frame, and the upper end of the transmission shaft is connected to the quantitative disk to drive the quantitative disk to rotate. The proximity sensor is arranged on the cover plate, and the acquisition end of the proximity sensor extends into the inner cavity of the quantitative disk. The bottom surface of the quantitative disk is recessed upward in the center, so that the internal cavity of the quantitative disk forms an annular cavity. A plurality of groups of material holes are evenly provided on the bottom wall of the annular cavity. The valve opening and closing part is arranged in the recess to control the opening or closing of the material holes, and the valve opening and closing part is connected to the frame.

[0008] The beneficial effects of the above solution: By using the rotation of the quantitative disk, the particles gather around the inner cavity of the quantitative disk under the action of centrifugal force. During the movement of the particles, the material holes will be filled. When the quantitative disk rotates to the corresponding position, the valve opening and closing part makes the material holes open, and the particles in the material holes fall.

[0009] The quantitative discharging structure of the above-mentioned filter rod particle adding device further has the following characteristics. The valve opening and closing part includes a cam disk, a baffle valve, and an elastic member. The cam disk is arranged in the recess and is connected to the frame. A plurality of radial slideways are evenly provided on the bottom wall of the quantitative disk. The baffle valve is arranged in the slideway. A through hole adapted to the material hole is provided on the baffle valve. The baffle valve is connected to the side wall of the slideway through an elastic member. One end of the baffle valve facing the recess extends into the recess. When the elastic member is in a natural state, the baffle valve will close the material hole. When one end of the baffle valve touches the convex part of the cam disk when the quantitative disk rotates, the baffle valve is pushed, and the through hole is aligned with the material hole to open it.

[0010] The beneficial effects of the above solution: Since the quantitative disk rotates continuously, but the cam disk remains stationary relative to the frame. When the baffle valve rotates to touch the convex part of the cam disk, the baffle valve is pushed, so that the through hole is aligned with the material hole. At this time, the material hole opens, and the particles therein fall into the blanking assembly under the action of gravity.

[0011] The quantitative discharging structure of the above-mentioned filter rod particle adding device further has the following characteristics. A baffle ring is further arranged in the quantitative disk. The baffle ring is located in the outermost circle of the annular inner cavity of the quantitative disk to guide some particles to the material holes.

[0012] Beneficial effects of the above solution: The function of the material baffle ring is to prevent the particles from completely aggregating at the outermost ring of the annular inner cavity of the metering disk, and can guide some particles to the material holes, so that the material holes are filled.

[0013] The metering and discharging structure of the above-mentioned filter rod particle adding device also has the following characteristics. A soft material deflecting piece is provided on the bottom wall of the cover plate. When the cover plate is closed at the opening of the metering disk, the deflecting piece obliquely extends into the annular cavity of the metering disk, and the lower end of the deflecting piece is close to the top surface of the material baffle ring.

[0014] Beneficial effects of the above solution: Since the cover plate does not rotate with the metering disk, as the metering disk rotates, the deflecting piece can continuously sweep off the particles aggregated on the material baffle ring, so that the particles can fill the material holes.

[0015] In summary, the beneficial effects of this solution are:

[0016] In the metering and discharging structure of the filter rod particle adding device provided by the present utility model, through the rotation of the metering disk, the particles in the metering disk move outward. During the moving process, the particles will fill the material holes until the material holes are opened, and the metered particles enter the next process. The metering and discharging structure of the filter rod particle adding device provided by the present utility model has the effect of metering and outputting particles. Description of the drawings

As Figures 1 - 5 shown, the quantitative discharging structure of the filter rod particle adding device provided in this embodiment includes a frame 1, a material bin 2, a feeding component 3, a quantitative component 4, and a discharging component 5. The material bin 2, the feeding component 3, the quantitative component 4, and the discharging component 5 are all arranged on the frame 1. The feeding component 3 is communicated with the material bin 2, the output end of the feeding component 3 is communicated with the feeding port of the quantitative component 4, the output end of the quantitative component 4 is correspondingly communicated with the discharging component 5, and a transmission component is arranged directly below the discharging component 5. The transmission component is used to convey the spaced filter rods forward. When the discharging component 5 is opened, the particles in the discharging component 5 just enter the gaps between the filter rods. The quantitative component 4 is used to receive the granular material output by the feeding component 3 and periodically and quantitatively output the material into the discharging component 5 to fill the granular material into the gaps between the filter rods.

[0027] It should be noted that the feeding component 3 is a negative pressure chamber, and the material in the material bin 2 is transferred to the quantitative disk 42 by negative pressure.

[0028] In the above embodiment, the metering component 4 includes a metering disk 42, a transmission shaft 45, a cover plate 41, a proximity sensor 43, and a valve opening and closing part. The top of the metering disk 42 is open, and the cover plate 41 is covered at the opening of the metering disk 42 to close the opening. A feed inlet is provided at the top of the cover plate 41, and the feeding component 3 is communicated with the feed inlet. The cover plate 41 is fixedly connected with the feeding component 3. A through hole is provided at the center of the bottom of the metering disk 42. The lower end of the transmission shaft 45 is in transmission connection with the driving mechanism in the frame 1, and the upper end of the transmission shaft 45 is connected with the metering disk 42 to drive the metering disk 42 to rotate. The proximity sensor 43 is arranged on the cover plate 41, and the acquisition end of the proximity sensor 43 extends into the inner cavity of the metering disk 42. The bottom surface of the metering disk 42 is recessed upward in the center, so that the internal cavity of the metering disk 42 forms an annular cavity. A plurality of groups of material holes 44 are uniformly provided on the bottom wall of the annular cavity. The valve opening and closing part is arranged in the recess to control the opening or closing of the material holes 44, and the valve opening and closing part is connected with the frame 1.

[0029] In the above embodiment, the valve opening and closing part includes a cam disk 46, a baffle valve 47, and an elastic member. The cam disk 46 is arranged in the recess and is connected with the frame 1. A plurality of radial sliding grooves are uniformly provided on the bottom wall of the metering disk 42. The baffle valve 47 is arranged in the sliding groove. A through hole adapted to the material hole 44 is provided on the baffle valve 47. The baffle valve 47 is connected with the side wall of the sliding groove through an elastic member. One end of the baffle valve 47 facing the recess extends into the recess. When the elastic member is in a natural state, the baffle valve 47 will close the material hole 44. When the metering disk 42 rotates to the position where one end of the baffle valve 47 contacts the convex part of the cam disk 46, the baffle valve 47 is pushed, and the through hole is aligned with the material hole 44 to open it.

[0030] In another preferred embodiment, the valve opening and closing part includes a cam disk 46 and a baffle valve 47. The cam disk 46 is arranged in the recess and is connected with the frame 1. A plurality of radial sliding grooves are uniformly provided on the bottom wall of the metering disk 42. The baffle valve 47 is arranged in the sliding groove. A through hole adapted to the material hole 44 is provided on the baffle valve 47. An annular groove is provided on the top surface edge of the cam disk, and the annular groove is not a standard circular ring. One end of the baffle valve 47 facing the cam disk 46 extends into the annular groove. When the metering disk 42 rotates, one end of the baffle valve 47 moves along the annular groove. When the baffle valve 47 rotates to the discharging position, the annular groove pulls the baffle valve 47 to make the through hole on it directly face the material hole. When the baffle valve 47 rotates beyond the discharging position, the annular groove pushes the baffle valve 47 to close the material hole.

[0031] In the above embodiment, a baffle ring 48 is further arranged in the metering disk 42. The baffle ring 48 is located at the outermost circle of the annular inner cavity of the metering disk 42 to guide some particles to the material holes 44.

[0032] In the above embodiment, a soft material pushing piece 49 is provided on the bottom wall of the cover plate 41. When the cover plate 41 is closed at the opening of the metering plate 42, the material pushing piece 49 obliquely extends into the annular cavity of the metering plate 42, and the lower end of the material pushing piece 49 is close to the top surface of the material blocking ring 48.

[0033] It should be noted that the blanking assembly 5 includes a driving wheel, a driven wheel, a transmission belt, an annular guide rail, and a plurality of receiving parts for receiving metered materials. The driving wheel and the driven wheel are both arranged on the frame 1. The transmission belt is sleeved on the driving wheel and the driven wheel. The driving wheel is in transmission connection with the driving structure in the frame 1. The plurality of receiving parts are evenly spaced and distributed on the transmission belt. The top of the back of the receiving part is fixedly connected to the transmission belt. The annular guide rail is arranged below the transmission belt, and the track of the annular guide rail is consistent with that of the transmission belt. The bottom of the back of the receiving part is engaged with the annular guide rail. When the driving wheel rotates, the transmission belt drives the receiving part to move along the annular guide rail.

[0034] It should be noted that the receiving part includes a hopper, a connecting body, a clamping body, and a material guiding groove. The hopper is arranged on the top of the material guiding groove and the two are communicated with each other. The opening of the hopper faces upward. An outlet is arranged at the bottom of the material guiding groove. The connecting body and the clamping body are both arranged on the back of the material guiding groove. The connecting body is above the clamping body. The connecting body is connected to the transmission belt. The clamping body is engaged with the annular guide rail. When the receiving part moves to the position for receiving materials, the clamping body closes the outlet. When the receiving part moves to the position for releasing materials, the clamping body opens the outlet.

[0035] It should be noted that the annular guide rail includes a first guide rail and a second guide rail. The first guide rail is closer to the metering assembly 4 than the second guide rail. The connection between the first guide rail and the second guide rail is a smooth transition. When the receiving part moves to the position for receiving materials, the clamping body reaches the second guide rail and contacts it. The second guide rail makes the clamping body move upward to close the outlet. When the receiving part moves to the position for releasing materials, the clamping body reaches the first guide rail and is in contact with it. The first guide rail makes the clamping body move downward to open the outlet.

[0036] It should be noted that the clamping body includes a socket cylinder and an extension slider. The extension slider is arranged on the back of the socket cylinder. The end of the extension slider away from the socket cylinder is adapted to the annular guide rail and can slide along the annular guide rail. The socket cylinder is sleeved on the outer periphery of the material guiding groove. The outlet of the material guiding groove is arranged in an inclined state. An inclined extension block is arranged on the inner side wall of the socket cylinder. When the socket cylinder moves upward to the limit, the inclined extension block completely fits the outlet of the material guiding groove to completely close it. When the socket cylinder moves downward, the inclined extension block is separated from the outlet, and the material slides down from the inclined extension block until it leaves from the lower end opening of the socket cylinder.

[0037] Working principle: The feeding component 3 uses negative pressure to convey the granular materials in the silo 2 to the metering plate 42. As the metering plate 42 rotates, the materials move towards the edge under the action of centrifugal force. During the movement, some materials will enter the material holes 44. When the material holes 44 rotate to the corresponding position, the baffle valve 47 is pushed by the protrusion of the cam disk 46, so that the through hole is communicated with the material holes 44, and the materials fall into the blanking component 5 under the action of their own gravity, achieving the effect of outputting materials at a constant speed and a fixed quantity.

[0038] The above is only a preferred embodiment of the present invention, and does not limit the implementation manners and protection scope of the present invention accordingly. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the content of the specification of the present invention should be included in the protection scope of the present invention.
