Description

Technical Field

[0001] This invention belongs to the technical field of filter rod production equipment, specifically relating to a filter rod bursting bead adding device. Background Technology

[0002] Adding flavor capsules involves continuously and spacedly inserting one or more easily breakable functional flavor capsules during the production process of the filter rod (i.e., cigarette filter). This allows smokers to controllably release unique flavors or add moisture and other functions during smoking, thereby enhancing the smoker's experience.

[0003] The invention patent with application number 202310083339.1 discloses a filter rod with non-composite burst beads of different sizes and its burst bead implantation system and method. It uses the negative pressure of the evenly distributed bead-collecting protrusions on the outer periphery of the bead-collecting disc to adsorb burst beads in the hopper and transfer the adsorbed burst beads to the bead-planting disc for feeding. However, it can only complete the addition of burst beads for one filter rod at a time and cannot achieve batch addition of burst beads for filter rods. In addition, since each bead-collecting protrusion of the bead-collecting disc needs to adsorb and transfer burst beads, each bead-collecting protrusion needs to be equipped with an independently controlled adsorption component so that when one bead-collecting protrusion is transferring burst beads, the burst beads on the other bead-collecting protrusions will not fall off. This greatly increases the difficulty of controlling the transfer of burst beads. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a filter rod bursting bead adding device, which has axial suction holes and a first axial blowing hole that are not interconnected in the support shaft, and uses the rotation of the bead picking cylinder to switch the rows of bead picking holes on the bead picking cylinder between an angular position one that connects to the discharge port and an angular position two that connects to the first axial blowing hole, effectively reducing the control difficulty of loading and unloading bursting beads.

[0005] To achieve the above and other related objectives, the present invention provides a filter rod bead adding device, comprising a vertical plate, a hopper, and a support shaft; the hopper and the support shaft are fixed on the same side of the vertical plate, and the support shaft is located below the hopper; the top of the hopper is provided with a feed inlet, and the bottom of the hopper is provided with a discharge outlet; a bead-collecting cylinder that rotatably connects to the discharge outlet is sealed outside the support shaft; multiple rows of bead-collecting holes are evenly opened on the outer periphery of the bead-collecting cylinder, and each row of bead-collecting holes includes multiple bead-collecting holes arranged along the axial direction of the bead-collecting cylinder; the support shaft is provided with an axial suction hole and a first axial blowing hole, the axial suction hole and the first axial blowing hole are not connected to each other, and the first axial blowing hole is located below the axial suction hole; the outer wall of the support shaft is provided with...

Each first air outlet is connected to a first axial blowing port, and the number and spacing of the first air outlets are matched with the number and spacing of the bead-taking holes in each row. When the bead-taking cylinder rotates, each row of bead-taking holes sequentially loads popping beads at one angle position connected to the discharge port and unloads popping beads at another angle position connected to the first axial blowing port. The air inlet is not connected to the bead-taking hole at the second angle position. This invention only requires controlling the rotation angle of the bead-taking cylinder to sequentially complete the loading and unloading of each row of popping beads, which not only reduces the control difficulty of loading and unloading popping beads but also allows for the addition of popping beads to batch filter rods, improving the production efficiency of composite filter rods.

[0006] Preferably, a bead-transfer block is provided below the support shaft, and the top surface of the bead-transfer block is an arc-shaped surface that fits against the outer wall of the bead-taking cylinder; the arc-shaped surface is provided with vertical direct bead holes corresponding to each of the first air outlet holes; the vertical direct bead holes are connected to the corresponding first air outlet holes through the bead-taking holes at two angle positions; the present invention uses the vertical direct bead holes of the bead-transfer block to guide the unloaded popping beads, so as to ensure that the unloaded popping beads can fall accurately into the filter rod, thereby improving the accuracy of popping bead addition.

[0007] Preferably, the bead transfer block is provided with multiple sensor mounting holes, and each sensor mounting hole is connected to each vertical bead transfer hole in a one-to-one correspondence; a popping bead sensor is provided in the sensor mounting hole, and the popping bead sensor is used to detect whether popping beads have passed through the corresponding vertical bead transfer hole, so as to confirm whether a new filter rod needs to be replaced to add popping beads.

[0008] Preferably, the support shaft is provided with a second axial blowing hole; the second axial blowing hole is located below the axial suction hole, and the second axial blowing hole is not connected to either the first axial blowing hole or the axial suction hole; the outer wall of the support shaft is provided with a plurality of second air outlet holes arranged along the axial direction of the support shaft, each second air outlet hole is connected to the second axial blowing hole, and the number and spacing of the second air outlet holes are adapted to the number and spacing of the bead-taking holes in each row of bead-taking holes; a receiving box is fixed to one side of the bead-transferring block; the receiving box is provided with a material receiving box that is aligned with the outer wall of the bead-taking cylinder. The bead-collecting port fits snugly; when the bead-collecting cylinder rotates, each row of bead-collecting holes switches between angle position one connecting to the outlet, angle position two connecting to the first axial air blowing hole, and angle position three connecting to the second axial air blowing hole; the second air outlet connects to the receiving port through the bead-collecting hole at angle position three; the suction port does not connect to the bead-collecting hole rotated to angle position three; this invention can transfer the popping beads that have not been successfully unloaded to the bead-transfer block to the receiving box for secondary unloading, so as to ensure that each bead-collecting hole can cycle through the loading and unloading of popping beads, thereby improving the utilization rate of the bead-collecting holes.

[0009] Preferably, the bead-removing tube includes a rotating cylinder and a bead-removing tube body sleeved on the rotating cylinder; the bead-removing tube body is detachably fixed on the rotating cylinder to facilitate separate cleaning and unblocking of the bead-removing tube body.

[0010] Preferably, the upright plate is provided with a feeding block whose vertical position is adjustable, and the feeding block is provided with a feeding pipe that corresponds one-to-one with each vertical bead hole. The feeding pipe is connected to the corresponding vertical bead hole through a flexible tube so as to add the bursting beads to different height positions of the filter rod.

[0011] Preferably, the feeding pipe is provided with an installation block; the installation block is fixed to the feeding block by a position locking mechanism; the position locking mechanism includes a locking bolt, multiple through holes on the feeding block and threaded holes on the installation block; the bolt shank of the locking bolt passes through different through holes and is threadedly connected to the threaded holes of the installation block; the bolt head of the locking bolt cannot pass through the through holes; by simply passing the locking bolt through different through holes and threading it to the installation block, the installation block can be locked at different positions, so as to meet the requirements for adding burst beads to the filter rod at different positions.

[0012] Preferably, the feeding block is provided with a sliding groove parallel to the axial direction of the support shaft, and the mounting block is slidably installed in the sliding groove; the multiple through holes in the position locking mechanism are interconnected to form a clearance groove for the clearance bolt rod, and the extension direction of the clearance groove is consistent with the extension direction of the sliding groove; in this way, the position adjustment of the mounting block can be easily achieved by simply loosening the locking bolt.

[0014] Preferably, the rotating assembly includes a rotary motor, which drives the bead-picking cylinder to rotate via a transmission assembly.

[0016] This application features non-interconnected axial suction holes and a first axial blowing hole on the support shaft, and a bead-collecting cylinder is rotatably sleeved outside the support shaft. The rotation of the bead-collecting cylinder allows each row of rotating bead holes to switch between forming a suction channel and a first blowing channel, thus eliminating the need for frequent control of the start and stop of suction and achieving automatic loading and unloading of the beads, effectively reducing the difficulty of loading and unloading the beads. In addition, the second axial blowing hole on the support shaft can also connect with the receiving box through the rotating rows of bead-collecting holes, allowing unloaded beads to be transferred to the receiving box for re-unloading, thereby reducing the frequency of downtime to clear the bead-collecting holes and improving the production efficiency of the composite filter rod.

Detailed Implementation

[0031] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0032] Please see Figures 1 to 12 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the scope of the invention and therefore have no substantial technical significance.

[0033] For ease of description, this application defines the axial direction of the support shaft 30 as the front-back direction and the height direction of the support shaft 30 as the up-down direction. Therefore, the direction perpendicular to both the front-back and height directions can be defined as the left-right direction. Figure 3 The top and bottom sides of the paper are the up and down directions, respectively; the left and right sides are the left and right directions, respectively; and the outer and inner sides are the front and back directions, respectively.

[0034] Example 1

[0035] like Figures 1 to 3As shown, this embodiment provides a filter rod bead adding device, including a vertical plate 10, a hopper 20, a support shaft 30, and a bead-taking cylinder 41 that is sealed and rotates outside the support shaft 30; wherein, the hopper 20 and the support shaft 30 are both fixed on the same side of the vertical plate 10, and the support shaft 30 is located below the hopper 20; the top and bottom of the hopper 20 are respectively provided with a feed inlet and a discharge outlet; the top of the hopper 20 is provided with a cover plate 21 for opening or closing the feed inlet, and a handle can be formed on the cover plate 21 for convenient operation; the outer wall of the bead-taking cylinder 41 is fitted and connected to the discharge outlet of the hopper 20.

[0036] Multiple rows of bead-collecting holes are evenly distributed around the outer periphery of the bead-collecting cylinder 41, and each row of bead-collecting holes includes multiple bead-collecting holes 42 arranged along the axial direction of the bead-collecting cylinder; the support shaft 30 is provided with an axial suction hole 31 and a first axial blowing hole 32 that are not interconnected, and the first axial blowing hole 32 is located below the axial suction hole 31; the outer wall of the support shaft 30 is provided with a suction port 311 that communicates with the axial suction hole 31 and multiple first air outlet holes 321 that are spaced apart along the axial direction of the support shaft; the suction port 311 is located at the discharge port of the hopper 20 to ensure that when any row of bead-collecting holes is rotated to angle position one (i.e., between the discharge port and the suction port 311), the suction port 311 can generate a negative pressure suction force for each bead-collecting hole 42 in that row of bead-collecting holes to adsorb the popping beads at the discharge port and complete the popping bead loading; each first air outlet hole 321 is connected to the first axial blowing hole 32, and each first air outlet hole The number and spacing of 321 must be consistent with the number and spacing of the bead-taking holes 42 in each row of bead-taking holes, so as to ensure that when any row of bead-taking holes rotates to angle position two, each bead-taking hole 42 in that row can be connected to the first axial blowing hole 32 through the corresponding first air outlet 321. In this way, when the bead-taking cylinder 41 rotates, each row of bead-taking holes can load popping beads at one angle position connected to the discharge port and unload popping beads at angle position two connected to the first axial blowing hole 32, so as to complete the loading and unloading of popping beads in each row in a cycle. In order to ensure the smooth unloading of popping beads, the suction port 311 must not be connected to the bead-taking hole 42 rotated to angle position two. In this embodiment, for the same row of bead-taking holes, the multiple bead-taking holes 42 can be arranged at equal intervals or unequal intervals, which is not limited. This embodiment preferably adopts the method of equal interval arrangement.

[0037] It should be noted that, in order to prevent the loaded popping beads from falling before reaching angle position two, the air intake 311 must always remain connected to the bead removal hole 42, which is loaded with popping beads before reaching angle position two.

[0038] Specifically, when the bead-collecting cylinder 41 rotates to rotate a row of bead-collecting holes to angle position one, the suction port 311, which is connected to the axial suction port 31, can connect with the receiving port through the row of bead-collecting holes, thereby completing the adsorption of popped beads in that row of bead-collecting holes; as the bead-collecting cylinder 41 continues to rotate, the row of bead-collecting holes 41 can always be connected with the suction port 311 before rotating to angle position two, so as to ensure sufficient adsorption force and prevent the popped beads loaded on them from falling off; when the row of bead-collecting holes rotates to angle position two, each bead-collecting hole 42 in the row of bead-collecting holes can be connected to each of the first blowing holes 321 one by one, thereby realizing the unloading of popped beads under the action of blowing, and the unloaded popped beads will fall into the corresponding filter rod, completing the addition of popped beads to the batch filter rods.

[0039] like Figure 2 As shown, each end of the bead-retrieving cylinder 41 has a stepped bearing mounting hole. A sealing ring (not shown) and a bearing 81 are installed in each bearing mounting hole, with the sealing ring located inside the corresponding bearing 81. Simultaneously, bearing caps 82 are bolted to both ends of the support shaft 30. The bearing caps 82 restrict the axial movement of the corresponding bearing 81. Thus, the bead-retrieving cylinder 41 can be rotatably mounted outside the support shaft 30 via two bearings 81, thereby restricting the axial movement of the bead-retrieving cylinder 41 while allowing it to rotate freely. Furthermore, one of the bearing caps... The cover 82 needs to be hollow, and a suction pipe 821 connected to the suction device is formed at the end away from the support shaft 30. In this way, a continuous suction force can be provided to the axial suction hole 31 in the support shaft 30. Of course, the other bearing cover 82 also needs to be equipped with an air inlet that is connected to the first axial blowing hole 32. In this way, the air from the air supply device can be continuously sent into the axial blowing hole through the air inlet to ensure the smooth unloading of the bursting beads. This arrangement can ensure that the air supply device and the suction device can be located at the two ends of the support shaft 30 respectively, effectively avoiding the problem of interference between the air supply device and the suction device.

[0040] Furthermore, such as Figure 1 , Figure 2 and Figure 11 As shown, a bead transfer block 50 is provided below the support shaft 30; the top surface of the bead transfer block 50 is an arc-shaped surface that fits against the outer wall of the bead taking cylinder 41, and the arc-shaped surface is provided with vertical direct bead holes 51 that correspond one-to-one with each of the first air outlet holes 321; in this way, the vertical direct bead holes 51 can be connected to the corresponding first air outlet holes 321 through the bead taking holes 41 at two angle positions, so as to ensure that the unloaded popping beads can smoothly enter the filter rod below through the vertical direct bead holes 51, thereby improving the accuracy of popping bead addition.

[0041] like Figure 1 and Figure 11As shown, the bead transfer block 50 is provided with multiple sensor mounting holes 52, and each sensor mounting hole 52 is connected to each vertical bead transfer hole 51 in a one-to-one correspondence; a popping bead sensor 53 is provided in the sensor mounting hole 52, and the popping bead sensor 53 is used to detect whether a popping bead has passed through the corresponding vertical bead transfer hole 51, so that the operator can understand the popping bead addition status; the popping bead sensor 53 can be a through-beam photoelectric sensor or a reflective photoelectric sensor (when no signal is received, it indicates that a popping bead has passed through), and there is no limitation on this. In this embodiment, the popping bead sensor 53 is preferably a through-beam photoelectric sensor.

[0042] Furthermore, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12 As shown, the support shaft 30 is provided with a second axial blowing hole 33; the second axial blowing hole 33 is located below the axial suction hole 31, and the second axial blowing hole 33 is not connected to the first axial blowing hole 32 and the axial suction hole 31; the outer wall of the support shaft 3 is provided with a plurality of second air outlet holes 331 arranged along the axial direction of the support shaft, each second air outlet hole 331 is connected to the second axial blowing hole 33, and the number and spacing of the second air outlet holes 331 must be consistent with the number and spacing of the bead picking holes 42 in each row of bead picking holes; a receiving box 60 is fixed to one side of the bead transfer block 50, and the receiving box 60 is provided with a receiving port that fits against the outer wall of the bead picking cylinder. The position of the receiving port must be close to all the second air outlet holes 311 so that any When a row of bead-collecting holes rotates to angle position three, each second air outlet 311 can connect with the receiving port through the corresponding bead-collecting hole 42 in that row of bead-collecting holes. Thus, when the bead-collecting cylinder 41 rotates, each row of bead-collecting holes can rotate from angle position one connecting to the discharge port to angle position two connecting to the first axial blowing hole 32, and then to angle position three connecting to the second axial blowing hole 33. At this time, the second air outlet 331 connects with the receiving port through the bead-collecting hole 42 at angle position three, so as to re-unload the bursting beads that were not successfully unloaded at angle position two, so as to reduce or avoid the impact caused by the blockage of the bead-collecting hole 42. The suction port 311 should not connect with the bead-collecting hole 42 rotated to angle position three, so as to avoid affecting the re-unloading of the bursting beads.

[0043] The secondary unloading function can effectively reduce the risk of the bead-removing hole 42 failing due to bead bursting blockage, thereby effectively reducing the frequency of disassembling and cleaning the bead-removing cylinder 41 and shortening the bead bursting addition cycle of batch composite filter rods.

[0044] like Figure 3 , Figure 8 and Figure 9As shown, the bead-retrieving cylinder 41 includes a rotating cylinder 411 and a bead-retrieving cylinder body 412 sleeved outside the rotating cylinder 411. The bead-retrieving cylinder body 412 is detachably fixed to the rotating cylinder 411 by bolts, strong magnets, or other means. The bead-retrieving hole 42 of the bead-retrieving cylinder 41 consists of a bead-suction hole 42b and an air passage hole 42a that are interconnected. The bead-suction hole 42b is located on the outer wall of the bead-retrieving cylinder body 412, and the air passage hole 42a is located on the outer wall of the rotating cylinder 411. The bead-suction hole 42b is a stepped hole or a conical hole, and the bead-suction hole 42b is close to the bead-retrieving cylinder body. The diameter of one end of the center line of the body 412 is smaller than the diameter of the end of the bead suction hole 42b that is far from the center line of the bead-removing cylinder body 412, so as to prevent the popping beads sucked in by the bead suction hole 42b from entering the support shaft 30 through the corresponding air passage 42a. Since the bead-removing cylinder 41 is composed of a separate rotating cylinder 411 and a bead-removing cylinder body 412, when the popping beads enter the bead suction hole 42b and cannot be unloaded, it is not necessary to disassemble the entire bead-removing cylinder 41. Only the bead-removing cylinder body 412 needs to be disassembled for bead cleaning, which effectively reduces the number of disassembly and assembly parts involved in bead cleaning and shortens the bead cleaning cycle.

[0045] Of course, the bead-removing tube 42 can also be integrally formed. In this case, the bead-removing hole 42 is a stepped hole or a conical hole, and the diameter of the end of the bead-removing hole 42 near the center line of the bead-removing tube 41 is smaller than the diameter of the end of the bead-removing hole 42 away from the center line of the bead-removing tube 41, so as to prevent the adsorbed popping beads from entering the support shaft 30.

[0046] like Figure 1 and Figure 10 As shown, the upright plate 10 is provided with a rotating assembly for driving the bead-retrieving cylinder 41 to rotate. The rotating assembly includes a rotating motor 91, which drives the bead-retrieving cylinder 41 to rotate through a transmission assembly. The transmission assembly includes a driving wheel 92 fixed on the motor shaft of the rotating motor 91 and a driven wheel 93 fixed on the bead-retrieving cylinder 41. The driving wheel 92 and the driven wheel 93 are connected by gear teeth, a synchronous belt, or a synchronous chain.

[0047] Furthermore, such as Figure 1 As shown, the vertical plate 10 is provided with a feeding block 71 whose vertical position is adjustable. The feeding block 71 is provided with a feeding pipe 72 that corresponds one-to-one with each vertical direct bead hole 51. The feeding pipe 72 is connected to the corresponding vertical direct bead hole 51 through a flexible tube. Since the feeding block 71 can drive the feeding pipe 72 to move up and down, it is convenient to add the bursting beads to different height positions of the filter rod to better meet the needs of users.

[0048] Preferably, the vertical position adjustment of the drive unloading block 71 is achieved by a lifting assembly. The lifting assembly can be an automatic lifting device such as a cylinder, hydraulic cylinder, or electric push rod. Alternatively, the unloading block 71 can be fixed at different height positions on the upright plate 10 by bolts. There is no limitation on this. In this embodiment, the lifting assembly is preferably a cylinder.

[0049] Furthermore, such as Figure 1 As shown, the feeding tube 72 is provided with a mounting block 73. The mounting block 72 is preferably a clamping block to reduce the difficulty of disassembly and assembly. The mounting block 73 is fixed to the feeding block 71 by a position locking mechanism. The position locking mechanism includes a locking bolt 74, multiple through holes on the feeding block and threaded holes on the mounting block 73. The bolt shank of the locking bolt 74 passes through different through holes and is threadedly connected to the threaded holes of the mounting block 73. The bolt head of the locking bolt 74 cannot pass through the through holes. In this way, the horizontal position of the feeding tube 72 can be adjusted as needed.

[0050] Preferably, such as Figure 1 As shown, the feeding block 71 is provided with a sliding groove 711 parallel to the axial direction of the support shaft, and the mounting block 73 is slidably installed in the sliding groove 711; multiple through holes in the position locking mechanism are interconnected to form a clearance groove for the clearance bolt rod, and the extension direction of the clearance groove is consistent with the extension direction of the sliding groove 711; thus, the position of the feeding tube 72 can be easily adjusted by simply loosening the locking bolt 74 to meet the needs of adding burst beads with different filter rod spacing.

[0051] Example 2

[0052] The only difference between this embodiment and Embodiment 1 is the way the bead-receiving cylinder 41 and the support shaft 30 are matched.

[0053] Specifically, the bead-retrieving cylinder 41 is directly mounted on the support shaft 30 and two retaining rings are installed on the support shaft 30 to restrict the axial movement of the bead-retrieving cylinder 41. In this way, the bead-retrieving cylinder 41 can be freely rotated but not axially moved while mounted on the support shaft 30. To ensure sealing, two sealing rings can be configured on the support shaft 30. The two sealing rings are located between the two retaining rings and at both ends of the bead-retrieving cylinder 41.

[0054] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
