Description

Technical Field

[0001] The utility model relates to cigarette filter rod manufacturing equipment, and more specifically, to an ALM particle adding device used for filter rod production. Background Art

[0002] The ALM particle adding module is located between the opener and the forming machine. Its main function is to add 20-50 mesh activated carbon, kudzu root and other particles to the filter rod filament belt according to certain process standards during the filter rod production process to produce material rods with specific functions, fragrances or appearances. During production, the particles in the ALM module hopper fall vertically onto the conveyor belt and are transported to the end to be added to the moving filament belt. Some particles are wrapped by the filament belt and carried into the forming machine to be rolled into filter strips, and finally cut into material rods of equal length. The remaining particles fall into the collection bucket of the ALM particle adding module and are recycled. The particle content of the material rod is mainly controlled by the speed of the conveyor belt motor. The faster the motor speed, the more particles are transported per unit time, and the higher the particle content of the material rod.

[0003] The acetate fiber tow used in the production of filter rods is fully opened and has a mesh structure with a certain elasticity. The tow belt will produce slight shaking during high-speed operation. When the ALM particle adding module adds particles, the particles fall vertically on the moving tow belt in a "waterfall" shape. The shaking tow belt will eject the particles from different directions and fall into the collection bucket, resulting in a low particle content in the tow belt, and then produce material rods with unstable or substandard particle content. In order to ensure that the particle content of the material rod meets the process requirements, the addition amount of the ALM module is increased as much as possible to make more particles fall into the tow belt. However, as the addition amount increases, the particles that rebound and break away from the tow belt also increase, with little effect, and the particles in the hopper will be quickly consumed. The particles in the collection bucket will also increase rapidly. The recovery speed is much slower than the collection speed, resulting in particle accumulation, requiring operators to frequently stop the machine for processing, increasing the workload of operators, and reducing the production continuity and effective operation rate of the equipment. In addition, increasing the motor speed will cause problems such as excessive motor load and accelerated wear of the conveyor belt.

[0004] Therefore, in order to solve the problems of low particle content in the material rod due to particle rebound when adding particles to the ALM module, and little effect after increasing the amount of addition, which will lead to decreased equipment efficiency and increased motor load, it is urgent to design a device that can avoid or weaken the shaking of the wire belt and ensure that the particle content of the material rod is qualified and stable.

[0034] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0035] according to Figure 1 and Figure 2 As shown, the utility model provides an ALM particle adding device for filter rod production, comprising a vacuum suction cup 1, a hopper 2, an opener and a forming machine;

[0036] The opening machine is used to open the filter rod tow band, and the forming machine is used to roll the filter rod tow band wrapped with ALM particles into filter rods;

[0037] The hopper 2 is arranged above the filter rod tow belt between the opener and the forming machine, and is used for feeding and conveying the ALM particles; the vacuum suction cup 1 is arranged below the filter rod tow belt between the opener and the forming machine to support the filter rod tow belt and can vacuum absorb the fallen ALM particles so that the ALM particles are wrapped in the opened filter rod tow belt.

[0038] The vacuum suction cup 1 of the utility model mainly functions to stabilize the filter rod wire band in motion, reduce the shaking amplitude of the filter rod wire band, and at the same time control the rebounded particles to fall back into the filter rod wire band again, thereby realizing secondary distribution and ensuring that the filter rod wire band carries more particles into the molding process, thereby producing material rods with stable particle content and meeting the standards.

[0039] Furthermore, the vacuum suction cup 1 includes a box body 101, the back side of the box body 101 is connected to a fixing block 105 through a support rod 104, and the fixing block 105 is connected to the rear fuselage wall panel through a fixing screw 106; a positioning ring 109 is provided on the front side of the box body 101, and a positioning rod 110 is provided on the positioning ring 109, and the positioning rod 110 is connected to the front fuselage wall panel.

[0040] The upper surface of the box body 101 is provided with a negative pressure suction cover plate 102, and a plurality of negative pressure air vents 103 are provided on the negative pressure suction cover plate 102. The bottom of the box body 101 is provided with a negative pressure pipe interface 111 for connecting negative pressure equipment. The main function of the negative pressure suction cover plate 102 is to support the filter rod tow belt, and stabilize the filter rod tow belt through the adsorption force generated by the eight negative pressure air vents 103, reduce the vibration of the filter rod tow belt and the rebound of particles, and at the same time adsorb the particles on the filter rod tow belt and smoothly bring them into the molding process.

[0041] Furthermore, the box body 101 and the box bottom are sealed and connected by a plurality of butterfly screws 108 on the side. The function of the butterfly screws 108 is to facilitate the disassembly and assembly of the box body 101 and to clean the box body 101 and the box bottom.

[0042] Furthermore, a waist-shaped hole 107 in the vertical direction is provided on the fixing block 105, and a fixing screw 106 is connected in the waist-shaped hole 107 to adjust the height of the vacuum suction cup 1; and a handle 115 for easy holding is also provided on the front side of the box body 101. The vacuum suction cup 1 is installed between the two support rollers 4, supported and positioned by two support rods 104 and four positioning rings 109. The two support rods 104 are respectively fixed to the fuselage wall panel by two fixing blocks 105 and two fixing screws 106. The vacuum suction cup 1 can adjust the fixing screws 106 and the positioning rings 109 according to the position of the wire band to obtain a relatively parallel and close position to the filter rod wire band.

[0043] Furthermore, a negative pressure regulating valve 112 is provided on the pipeline between the negative pressure pipe interface 111 and the negative pressure device. The main function of the negative pressure regulating valve 112 is to adjust the pressure of the negative pressure suction so that the negative pressure suction can just stabilize the filter rod tow band and particles, avoid excessive or insufficient negative pressure suction, and display the negative pressure value to guide the pressure adjustment of the negative pressure suction. The negative pressure regulating valve 112 is installed on the side of the ALM module body to facilitate dynamic adjustment during production operation.

[0044] Furthermore, a particle rebound cover plate 113 is provided on the upper side of the box body 101, and the particle rebound cover plate 113 is arranged above the filter rod wire band, so that after the particles escape from the filter rod wire band, they hit the particle rebound cover plate 113 and are rebounded and fall back onto the filter rod wire band.

[0045] Furthermore, a plurality of ribs 114 are provided on the top surface of the particle rebound cover plate 113 away from the negative pressure suction cover plate 102. The function of the ribs 114 is to increase the strength of the particle rebound cover plate 113 and prevent it from deforming.

[0046] Furthermore, a conveyor 3 is provided below the hopper 2, and the conveying direction of the conveyor 3 is opposite to the moving direction of the filter rod tow belt. During implementation, the conveyor 3 reduces the impact force of the ALM particles falling on the filter rod tow belt, thereby preventing a large number of ALM particles from being rebounded by the filter rod tow belt. In addition, the falling ALM particles are uniformly conveyed by the conveyor 3, and the uniformed ALM particles are centrally conveyed to the filter rod tow belt that has just been loosened. At the same time, the contact path between the ALM particles and the filter rod tow belt is increased, thereby ensuring that most of the ALM particles can be wrapped by the filter rod tow belt that has just been loosened in time.

[0047] Furthermore, a collecting bucket is provided at the bottom of the vacuum suction cup 1, and the remaining particles fall into the collecting bucket for recycling.

[0048] During production operation, the tow belt fully loosened and glued by the opener enters the ALM module, and quickly passes between the vacuum suction cup 1 particle rebound cover plate 113 and the negative pressure suction cover plate 102. Under the action of the negative pressure suction of the vacuum suction cup 1, the negative pressure air outlet 103 generates an adsorption force to adsorb and stabilize the filter rod tow belt. The conveyor 3 transports the particles to the moving filter rod tow belt, and clings to the filter rod tow belt under the adsorption force. A small number of rebounded particles break away from the filter rod tow belt and hit the particle rebound cover plate 113, and then rebound and fall back to the filter rod tow belt, playing the role of secondary cloth. Under the adsorption force of the negative pressure suction cover plate 102 and the rebound effect of the particle rebound cover plate 113, the tow belt passes smoothly through the ALM module and carries enough particles to ensure that the particle content of the output material rod meets the standard and is stable. At the same time, the filter rod tow belt that is attached to the negative pressure suction cover plate 102 and runs will take away the particles that have fallen on the suction cover plate and the negative pressure air outlet 103, playing a role of continuous cleaning and avoiding particle accumulation or blockage. The vacuum suction cup 1 of the utility model effectively ensures that the particle content of the filter rod is qualified and stable, and can also effectively reduce the frequency of shutdown due to particle accumulation, the labor intensity of the staff, the load of the ALM module conveying motor, and reduce the wear of the conveying belt.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
