Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette making equipment, in particular to a quantitative bead planting system. BACKGROUND

[0002] In the technical field of cigarette making equipment, the explosion bead cigarette has become an important product type in the global tobacco market due to its rich taste levels. China is the largest explosion bead cigarette consumption market in the world. With the diversification of consumer demand, explosion bead products show significant diversification characteristics: on the one hand, the physical properties of explosion beads are continuously expanding, covering different sizes (such as 1.5mm-4mm in diameter), brittleness (from easy to break to high toughness), and shapes (circular, oval, etc.); on the other hand, filter rod structures are also evolving towards complexity, and new structures such as binary composite filter rods and ternary composite filter rods are gradually becoming mainstream.

[0003] However, the existing explosion bead adding equipment cannot meet the above diversified needs, and there are two major core pain points: 1. Insufficient production flexibility: Traditional explosion bead adding modules are mostly designed with fixed structures, supporting only single-bead or double-bead adding modes, and cannot flexibly adjust the number of explosion beads added (such as single-bead, double-bead, and triple-bead switching) according to production needs. If different specifications of explosion bead cigarettes need to be produced, the equipment needs to be disassembled and modified on a large scale, which not only is cumbersome to operate, but also causes the production line to be shut down for a long time, seriously affecting production efficiency.

[0004] 2. Conflict between production efficiency and precision: The production speed of existing equipment is generally limited to 3 meters per minute, which cannot meet the market demand for high output. At the same time, due to the lack of effective trajectory control means during the explosion bead conveying process, at high speed, explosion beads are easily affected by centrifugal force, inertia, and other factors, causing material falling deviation, reducing the accuracy of explosion bead planting in filter rods, and producing a large number of unqualified products, increasing production costs.

[0005] In addition, the existing equipment also has problems such as complex specification switching process and inconvenient cleaning and maintenance. For example, when changing the specification of explosion beads, multiple components such as feeding, conveying, and adding need to be adjusted one by one, which requires high skills of operating personnel; when the equipment is shut down for cleaning, residual explosion beads are difficult to quickly empty, which easily causes cross-contamination risk, further restricting the improvement of production efficiency and product quality. Therefore, developing a quantitative bead planting system with high flexibility, high efficiency, high precision, and easy maintenance has become a key requirement to solve the current industry pain points.

Precise control of explosion bead trajectory, greatly improving the material falling precision and system stability In view of the problem that the existing equipment is easy to deviate under the centrifugal force when the blasting bead is conveyed at high speed, the system innovatively designs an inclined adsorption hole structure on the planting bead disc of the conveying assembly: the axis of the adsorption hole is arranged at an acute angle with the radial line of the planting bead disc, and is accurately matched with the positive and negative pressure channels of the second air distribution disc. When the blasting bead rotates at high speed with the planting bead disc, the negative pressure stably adsorbs the blasting bead in the blasting bead groove through the adsorption hole; when the blasting bead is conveyed to the dropping position, the positive pressure blows out the blasting bead through the inclined adsorption hole, and the airflow direction can offset the inertia and centrifugal force of the blasting bead, so that the blasting bead is in a nearly free-fall motion and vertically falls into the adding hopper of the adding assembly.

[0017] The design effectively avoids the problem of blasting bead dropping deviation, and the blasting bead implanting accuracy and production rate can be significantly improved, which improves the efficiency and significantly reduces the rate of unqualified products.

[0019] Strong adaptability to multiple specifications: when different sizes and shapes of blasting beads need to be replaced, only the key components (all adopt quick-release structure, quickly fixed by hand screwing and locking screw) of the feeding disc of the feeding assembly, the planting bead disc of the conveying assembly and the adding hopper of the adding assembly need to be replaced, without adjusting the overall structure of the equipment, adapting to the expansion of the blasting bead diameter range, covering the existing mainstream blasting bead specifications.

[0020] 3. Strong structure adaptability and adjustability, simplifying specification switching and maintenance process Double adjustment of overall height and spacing, adapting to different host equipment: The lifting adjustment frame drives the lifting plate to vertically slide through the lifting cylinder, which can realize the overall height adjustment of the system, accurately dock different types of filter rod production host, without modifying the host, improving the universality of the equipment.

[0025] Efficient cleaning design: the blasting bead cabin of the feeding disc is provided with a positive pressure through hole, which can be connected with the positive pressure hole one of the first air distribution disc to blow away the small impurities in the blasting bead cabin during cleaning; at the same time, the acrylic cover outside the feeding disc is fixed by hand screw, which can be quickly disassembled, so that the inside of the feeding disc can be thoroughly cleaned, and the maintenance difficulty is reduced.

[0026] Real-time monitoring and early warning: the sensor assembly is fixedly installed at the bottom of the air distribution chamber of the first air distribution disc, which can detect the residual blasting beads in the blasting bead cabin in real time, and automatically issue a replenishment warning when the residual amount is lower than the preset threshold, so as to avoid the production line shutdown caused by lack of material and further improve the production continuity.

DETAILED DESCRIPTION

[0031] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the present application will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the drawings structure is only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained without creative labor. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application.

[0032] Embodiments: Please refer to the drawings as Figures 1-12As shown, the embodiment provides a quantitative bead planting system, which comprises a feeding assembly 1, a conveying assembly 2, an adding assembly 3 and a lifting adjusting frame 5, a lifting plate 51 is vertically slidably arranged in the lifting adjusting frame 5, a lifting cylinder 52 is fixedly installed at the bottom of the lifting adjusting frame 5, and the lifting plate 51 is driven to lift by the lifting cylinder 52; A distance adjusting plate 6 is vertically slidably arranged at the middle of the lifting plate 51, the adding assembly 3 is fixedly installed around the distance adjusting plate 6 and the lifting end of the lifting adjusting frame 5, the feeding assembly 1 and the conveying assembly 2 are both fixedly installed with the distance adjusting plate 6, and a distance adjusting structure 7 is arranged between the distance adjusting plate 6 and the lifting plate 51 to adjust the distance between the conveying assembly 2 and the adding assembly 3; The conveying assembly 2 comprises a bead planting disc 21, a gas distribution disc two 22 and a second driving assembly 25, the gas distribution disc two 22 is fixedly installed with the second driving assembly 25, and a transmission shaft 24 of the second driving assembly 25 is fixedly installed in the middle of the bead planting disc 21 through the gas distribution disc two 22; A plurality of blasting bead grooves 212 are uniformly arranged on the circumferential surface of the bead planting disc 21, a suction hole 211 is arranged on the inner wall of the blasting bead groove 212, one end of the suction hole 211 penetrates through the side surface of the bead planting disc 21, and the axis of the suction hole 211 is arranged at an acute angle with the radial line of the bead planting disc 21; The feeding assembly 1 transmits the blasting beads into the blasting bead groove 212, the blasting bead groove 212 is communicated with the negative pressure end of the gas distribution disc two 22 through the suction hole 211 to realize the adsorption of the blasting beads, and the blasting bead groove 212 is communicated with the positive pressure end of the gas distribution disc two 22 through the suction hole 211 to realize the blowing of the blasting beads in the opposite direction of the tangential motion of the bead planting disc 21, and the blasting beads fall into the adding assembly 3.

[0033] Specifically, as shown, Figures 1-5 The lifting plate 51 is slidably connected in the vertical direction in the lifting adjusting frame 5 through two groups of slide rail assemblies, and is driven to lift and drop by the lifting cylinder 52, so that the components installed on the lifting plate 51 can move up and down as a whole, so that the system can match different sizes of devices, and the universal performance of the system is improved; The distance adjusting plate 6 is slidably connected in the vertical direction on the front surface of the lifting plate 51 through two groups of slide rail assemblies, and the distance adjusting structure 7 is arranged between the two groups of slide rail assemblies, the distance adjusting plate 6 is driven to move up and down and then positioned by adjusting the distance adjusting structure 7, so that the distance between the conveying assembly 2 and the adding assembly 3 can be adjusted, so that the blasting beads can be accurately dropped into the adding assembly 3, and the failure of the blasting beads planting can be prevented; During the process of adding the popping beads to the addition component 3, the bead-planting disc 21 rotates rapidly under the drive of the second drive component 25. When the popping beads adsorbed at its circumference are blown away by the positive pressure gas output from the gas distribution disc 22, they will fall downwards due to centrifugal force and inertia, rather than falling vertically. This movement will cause the popping beads to not fall accurately into the addition component 3 and its corresponding addition hopper 34, resulting in the electronic control system being unable to accurately control the synchronization of the conveying component 2 and the addition component 3, thus causing frequent errors in popping bead implantation. Therefore, by opening an inclined adsorption hole 211 at the bottom of the popping bead groove 212, and by setting the adsorption hole 211 at an angle to the radial line of the bead-planting disc 21, the direction in which the positive pressure gas blows the popping beads out through the adsorption hole 211 is opposite to the direction in which the popping beads rotate with the bead-planting disc 21. This counteracts the inertia of the popping beads moving forward, allowing them to fall almost vertically, thereby improving the accuracy of the popping beads falling into the corresponding addition hopper 34 and accurately controlling the time of the popping beads falling, significantly improving the stability of this system.

[0034] The valve plate 22 is axially preload adjustable and installed inside the flange seat 23. The flange seat 23 is fixedly installed to the adjusting plate 6 by locking screws. The second drive assembly 25 is fixedly installed to the flange seat 23.

[0035] Specifically, such as Figure 4 As shown, by adopting a tensioning structure between the air distribution plate 22 and the flange seat 23, a constant preload is achieved, which improves the alignment accuracy between the air distribution plate 22 and the bead plate 21, ensures stable positive and negative pressure delivery to the bead plate 21, and optimizes the feeding stability. The tensioning structure includes a compression spring. Multiple identical, corresponding blind mounting holes are evenly distributed on the opposing circular surfaces of the valve plate 22 and flange seat 23. A pressure block is movably connected within the blind mounting holes of the flange seat 23. A set screw is threaded onto the outer circular surface of the flange seat 23, with one end of the set screw pressed against one end of the pressure block. The other end of the pressure block is inserted into one end of the compression spring, and the other end of the compression spring abuts against the blind mounting holes of the valve plate 22. Several countersunk holes are evenly distributed around the valve plate 22 near its axis, and connecting bolts are installed within these countersunk holes. The threaded portion of the connecting bolts is threadedly connected to the flange seat 23. This tensioning structure is a previously applied technology; it is only used here to illustrate the structural principle of this application.

[0036] A semi-circular negative pressure groove 221 is provided on one side of the air distribution plate 22 facing the bead planting plate 21. The two ends of the negative pressure groove 221 are located on the top and bottom sides of the air distribution plate 22. A positive pressure hole 222 is provided at the bottom of the air distribution plate 22 near the negative pressure groove 221. The negative pressure groove 221 is connected to the negative pressure device to generate negative pressure, which adsorbs the popping beads into the popping bead groove 212 through the adsorption hole 211. The positive pressure hole 222 is connected to the positive pressure device to generate positive pressure, which blows the popping beads out of the popping bead groove 212 and into the adding component 3 through the adsorption hole 211.

[0037] Specifically, as shown in Figures 4-6 The planting bead disc 21 is fixedly installed with the transmission shaft 24 of the second driving assembly 25. The planting bead disc 21 rotates clockwise through the rotation of the transmission shaft 24. The negative pressure device connects the negative pressure into the negative pressure groove 221. The positive pressure device connects the positive pressure into the positive pressure hole two 222. When the blasting beads rotate with the planting bead disc 21, the adsorption hole 211 on the planting bead disc 21 is affected by the negative pressure in the negative pressure groove 221, and the blasting beads are adsorbed in the blasting bead groove 212. When the planting bead disc 21 rotates to the lower side, the adsorption hole 211 on the planting bead disc 21 is aligned with the positive pressure hole two 222, the blasting beads are blown out of the blasting bead groove 212 by the positive pressure gas and fall into the adding assembly 3 below.

[0038] The adding assembly 3 includes a group of driving wheel assemblies 31, a group of tensioning wheel assemblies 4 and two groups of driven wheel assemblies 32 fixedly installed on the lifting plate 51.

The top material opening of the adding hopper 34 is located below the planting bead disc 21. The tensioning wheel assembly 4 tensions the synchronous chain 33.

[0039] Specifically, as shown in Figure 11 The driving wheel assembly 31 rotates under the driving of the servo motor, drives the synchronous chain 33 and the adding hopper 34 fixedly installed on the synchronous chain 33 to rotate. The synchronous chain 33 drives the driven wheel assembly 32 and the tensioning wheel assembly 4 to rotate.

[0040] The distance adjusting structure 7 includes an adjusting block 71, an adjusting screw 73 and two pulling blocks 72. The pulling block 72 is L-shaped.

The other end is T-shaped and clamped in the notch.

[0041] As shown in Figure 12 The six-hole head at the top of the adjusting screw 73 is rotated forward and backward, so that it moves upward relative to the adjusting block 71, so that the T-shaped head at the bottom is clamped with the two pulling blocks 72, so that the distance adjusting plate 6 moves up and down, the distance between the blasting bead groove 212 and the adding hopper 34 is adjusted, and the time and position of the blasting beads falling are further accurately controlled.

[0042] The feeding assembly 1 includes a first driving assembly 16. The front end of the first driving assembly 16 is fixedly installed with a gas distribution disc one 13. The output shaft 14 of the first driving assembly 16 is fixedly installed in the middle of the feeding disc 12 through the gas distribution disc one 13. The feeding disc 12 is provided with a acrylic cover 11 around the four circumferential surfaces of one side. The blasting beads in the feeding disc 12 are discharged through the blasting bead outlet at the bottom of the acrylic cover 11.

[0043] The acrylic cover 11 is uniformly provided with a plurality of groups of hand screws around the periphery, and the acrylic cover 11 is fastened and connected with the distance adjusting plate 6 through the plurality of groups of hand screws.

[0044] A plurality of blasting bead cabins 123 are uniformly and radially arranged on the periphery of the one side of the feeding disc 12, a positive pressure through hole 121 is arranged in the blasting bead cabin 123, and a recovery port 122 is arranged on the circumferential surface of the feeding disc 12 and communicates with the blasting bead cabin 123. The one side of the gas distribution disc 13 is concave to form a gas distribution chamber, the blasting bead cabin 123 and the recovery port 122 are arranged inside and outside the gas distribution chamber, a plurality of positive pressure holes 131 are uniformly arranged on the periphery of the gas distribution chamber, an inlet port 132 is arranged on one side of the gas distribution chamber and corresponds to the blasting bead cabin 123, a negative pressure hole 133 is arranged on one side of the bottom of the gas distribution disc 13 and corresponds to the recovery port 122, and the gas distribution disc 13 is fixedly installed with the distance adjusting plate 6.

[0045] The sensor assembly 15 is fixedly installed on the bottom of the gas distribution chamber of the gas distribution disc 13 and detects the remaining amount of the blasting beads in the blasting bead cabin 123.

[0046] Specifically, as shown in the figure, Figures 7-10 The first driving assembly 16 drives the rotation to drive the feeding disc 12 to rotate, the blasting beads enter the blasting bead cabin 123 of the feeding disc 12 through the inlet port 132 of the gas distribution disc 13, and the blasting beads quickly enter the blasting bead cabin 123 of the feeding disc 12 under the positive pressure of the positive pressure hole 131 of the gas distribution disc 13, and the blasting beads rotate in the acrylic cover 11 with the feeding disc 12 and are covered by the acrylic cover 11 to prevent the blasting beads from falling out, the blasting beads rotate to the lower end and the connecting position of the planting disc 21, fall into the blasting bead groove 212 of the planting disc 21 from the lower end of the acrylic cover 11, and when the recovery port 122 of the feeding disc 12 is aligned with the negative pressure hole 133 of the gas distribution disc 13, the blasting beads fall from the blasting bead groove 212 to the recovery port 122 due to the gravity, and the negative pressure hole 133 recycles the remaining blasting beads in the feeding disc 12, so that the blasting beads in the feeding disc 12 are quickly emptied.

[0047] The working principle of the quantitative planting bead system is as follows: after the system is fixed on the rack of the cavity blasting bead adding device, the overall height of the system is adjusted through the lifting cylinder 52, so that the discharging port is kept at a preset interval from the position of the smoke gun cloth belt cavity, and the blasting beads are accurately dropped into the filter rod cavity. After the host starts, the system synchronously starts with the host. The feeding disc 12 is driven to move counterclockwise, and the blasting beads are arranged in the blasting bead cabin 123 of the feeding disc 12 in a suspended state under the positive pressure blowing. The acrylic cover 11 coaxially arranged on the feeding disc 12 limits the blasting beads in the blasting bead cabin 123, and only the bead discharging port is arranged at the joint with the bead planting disc 21. After the blasting beads enter the blasting bead groove 212 on the bead planting disc 21, the adsorption hole 211 on the bead planting disc 21 is communicated with the negative pressure groove 221 on the gas distribution disc 2, and the negative pressure adsorbs the blasting beads in the blasting bead groove 212 to follow the bead planting disc 21 to move clockwise. When the bead planting disc 21 rotates to the lower side, the adsorption hole 211 on the bead planting disc 21 is communicated with the positive pressure hole 2 222 on the gas distribution disc 2, and the positive pressure blows the blasting beads to fall into the adding hopper 34 of the adding assembly 3. The blasting beads are free falling into the lower composite filter rod cavity section. The adding hopper 34 continues to move forward, and the above process is repeated to realize the adding of the blasting beads.

[0048] When the device is stopped or overhauled, the negative pressure hole 1 133 on the right side of the dosing disc 13 is communicated with the recycling port 122 of the feeding disc 12, so that the blasting beads in the feeding disc 12 can be quickly emptied into the recycling device by one key.

[0049] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not used to limit the protection scope of the present application.
