Description

Technical Field

[0001] The utility model relates to the technical field of detecting the characteristics of bursting beads, in particular to a measuring instrument for the strength of bursting bead particles. Background Art

[0002] In order to meet the needs of consumers, China Tobacco has increased the intensity of industrial upgrading and developed many new products such as bursting bead cigarettes and new cigarettes. Among them, bursting bead cigarettes are deeply loved by consumers because of their diverse flavors, and their production capacity is also increasing. During the smoking process of bursting bead cigarettes, the cigarette capsules wrapped in the filter rod, that is, "bursting bead particles", need to be pinched to taste the special flavor. Due to different production processes of bursting beads, the quality of bursting beads is also different.

[0003] Since the bursting beads need to achieve the sensory effect of being pinched and burst by hand, the bursting beads must meet the requirements of appropriate breaking strength and appropriate deformation. The strength and deformation of the bursting beads are important indicators that comprehensively reflect the comfort level of the hand feeling when the capsule is pinched. Among them, the strength of the bursting beads needs to be controlled within a certain range, and the strength value cannot be too low or too high: if the strength is too low, the processability during rod making is low and the capsule is easily broken; if it is too high, consumers cannot easily pinch it and the user experience is poor. These data are crucial for evaluating the taste release effect, pressure resistance performance and product quality stability of the bursting beads, and are important bases for tobacco manufacturers to optimize the formula and improve product quality.

[0004] At present, there are mainly two types of similar equipment on the market. The first is manual measurement, which uses manual placement of bursting beads and measures the bursting force by rotating the screw to apply pressure.

[0054] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the drawings.

[0055] Please refer to Figures 1 to 6 A specific embodiment of a bead particle strength measuring instrument shown. The bead particle strength measuring instrument realizes compatibility with multiple specifications of beads by setting at least one hopper assembly. After sampling the beads by the hopper assembly, the beads are transported to the pressing assembly by the conveyor and dividing assembly. The pressing assembly presses the beads to measure the strength of the beads, and the accurate data obtained by the measurement is displayed through an industrial computer, solving the problems that the existing equipment has uncontrollable transportation process, is easy to damage the beads, and the operation is cumbersome and the efficiency is low when changing the types of beads.

[0056] As Figures 1 to 6As shown, in this embodiment, the bead particle strength measuring instrument includes a body 1 with a workbench 11, at least one hopper assembly 2 disposed on the body 1 and having one end located on the workbench 11, a conveying and distributing assembly 3 disposed on the body 1 and cooperating with the hopper assembly 2, and a pressing assembly 4 located downstream of the conveying and distributing assembly 3 during operation; the hopper assembly 2 includes a hopper tray 21 located on the workbench 11 and a driving assembly 22, the hopper tray 21 is connected to the driving end of the driving assembly 22, and the hopper tray 21 is used for taking material based on the drive of the driving assembly 22; the conveying and distributing assembly 3 includes a guide rail 32, a receiving cylinder 33, and a power control member 34, the receiving cylinder 33 is slidably disposed on the guide rail 32 and moves to the discharging position of the hopper tray 21 based on the drive of the power control member 34, and a receiving hole 331 is provided on the receiving cylinder 33 for receiving material; the receiving cylinder 33 moves to the pressing assembly 4 through the guide rail 32, and the pressing assembly 4 is used for pressing and measuring.

[0057] Specifically, as Figure 1 shown, one side of the body 1 forms a workbench 11 for placing a plurality of hopper trays 21. Workers put beads of different specifications into the corresponding hopper trays 21. The hopper trays 21 take samples of the placed beads. The receiving cylinder 33 in the conveying and distributing assembly 3 slides along the guide rail 32 back and forth between the hopper assembly 2 and the pressing assembly 4 based on the drive of the power control member 34. The receiving cylinder 33 in the conveying and distributing assembly 3 is used to receive the beads falling from the hopper tray 21, and the beads are limited and fixed through the receiving hole 331 on the conveying and distributing assembly 3 to prevent the beads from rolling. The conveying and distributing assembly 3 that has received the beads moves along the guide rail 32 and places them into the pressing assembly 4. The pressing assembly 4 presses the beads to measure their strength. The conveying and distributing assembly 3 conveys the beads through the receiving cylinder 33, and adopts flexible lifting and conveying, which greatly avoids the problem that the traditional equipment damages the beads by conveying them through pipes, resulting in inaccurate measurement results.

[0058] It can be understood that the body 1 uses a profile frame 17 as the overall support structure. By installing a bottom plate 12, side plates 13, a top plate 14, a rear plate 16, and a front panel 15 on the profile frame 17, the body 1 is enclosed. A workbench 11 convenient for workers to operate is concavely provided at the top or convexly provided at the bottom of the front panel 15 of the body 1. Workers put beads of different specifications into the hopper trays 21 provided on the workbench 11. The driving assembly 22 connected to the bottom of the hopper tray 21 is located inside the workbench 11 to drive the hopper tray 21 to work. A waste box 18 is also provided inside the body 1 for recycling waste.

[0059] Specifically, as Figure 2As shown in the figure, the hopper plate 21 includes a cylinder body 211 and a material distribution plate 213 coaxially arranged inside the cylinder body 211. The bottom of the material distribution plate 213 is connected to the driving end of the driving assembly 22. The material distribution plate 213 rotates along the cylinder body 211 based on the drive of the driving assembly 22. Leakage holes 2131 are provided on the top edge side of the material distribution plate 213, and a blanking port 2121 is provided at the bottom of the cylinder body 211. When the material distribution plate 213 rotates, the leakage holes 2131 communicate with the blanking port 2121 correspondingly. When the leakage holes 2131 correspond to the blanking port 2121, the bursting beads roll out of the cylinder body 211 through the channel formed by the leakage holes 2131 and the blanking port 2121, and the falling bursting beads are received by the receiving cylinder 33. The receiving hole 331 on the receiving cylinder 33 is aligned with the blanking port 2121 to restrict the rolling of the bursting beads falling on the receiving cylinder 33 and prevent the bursting beads from rolling off the receiving cylinder 33.

[0060] Exemplarily, as Figure 2 shown in the figure, the cylinder body 211 can be set as a cylinder with openings at both ends and installed on the workbench 11. The bottom of the cylinder body 211 is detachably connected with a chassis 212. The chassis 212 is attached to the bottom of the material distribution plate 213. The blanking port 2121 penetrates through the chassis 212, and the radial position of the blanking port 2121 along the axis of the cylinder body 211 coincides with the radial position of the leakage holes 2131 along the axis of the cylinder body 211, so that the leakage holes 2131 communicate with the blanking port 2121 correspondingly. The detachable connection between the cylinder body 211 and the chassis 212 facilitates disassembly and cleaning. The chassis 212 is attached to the bottom of the material distribution plate 213 to prevent the bursting beads from falling between the chassis 212 and the material distribution plate 213 and falling through the blanking port 2121. And the fitting of the two makes it possible to pass only one bursting bead when the leakage holes 2131 communicate with the blanking port 2121 correspondingly, completing one sampling operation and avoiding taking too many bursting beads at one time, which affects the measurement accuracy. Preferably, the thickness of the material distribution plate 213 can be equal to the diameter of the bursting bead, which is convenient for individual sampling operation, and the diameter of the leakage holes 2131 is adjusted according to the diameter of the bursting bead.

[0061] It should be noted that the driving assembly 22 includes a first stepping servo motor 221, a motor seat 222 for fixing, a coupling 223 connected to the driving end of the first stepping servo motor 221. The coupling is connected with a rotating shaft 224. The rotating shaft 224 extends through the chassis 212 and is connected to the bottom of the material distribution plate 213. A hole is provided at the center of the chassis 212 for the rotating shaft 224 to pass through and be connected to the material distribution plate 213. The first stepping servo motor 221 drives the coupling 223 to drive the rotating shaft 224 to rotate, and the material distribution plate 213 connected to the rotating shaft 224 rotates inside the cylinder body 211. The driving assembly 22 is not limited to the stepping servo motor, and other components for providing power can also be used.

[0062] Specifically, as Figure 2 and Figure 3As shown in the figure, the hopper tray 21 further includes a diversion block 214 and a positioning block 215. The diversion block 214 is arranged inside the cylinder body 211 and is located on the side of the material leakage hole 2131 for diversion. One side of the positioning block 215 is fixedly connected to the cylinder body 211, and one end of the positioning block 215 is connected to the workbench 11. The center of the material distribution plate 213 protrudes upward along the axis of the cylinder body 211 for diversion. A diversion wall 2141 is formed on one side wall of the diversion block 214. The diversion wall 2141 is a vertically inclined arc surface. Preferably, the center of the material distribution plate 213 protrudes upward to make the whole shape like a frustum of a cone or a conical frustum. The diversion block 214 is arranged inside the cylinder body 211. When the staff puts a large number of bursting beads into the hopper tray 21, the bursting beads will accumulate inside the cylinder body 211. Therefore, it is necessary to set the diversion block 214 to divert the bursting beads. In addition, the diversion wall 2141 of the diversion block 214 for guiding the bursting beads is set as an inclined wall so that the bursting beads can cross the diversion block 214 to prevent the bursting beads from accumulating on the diversion block 214 and causing blockage.

[0063] Specifically, as Figure 4 shown, the conveying and distributing assembly 3 further includes a plate body 31 arranged inside the machine body 1, a pulley assembly 35 installed on the plate body 31, a synchronous belt 36 matched with the pulley assembly 35, a guide rail 32 arranged on the plate body 31, and a power control member 34 controlling the movement of the synchronous belt 36. A connecting piece 311 is arranged on the synchronous belt 36. The connecting piece 311 is connected with a power unit 342, and the power unit 342 is connected with a material receiving cylinder 33. The movement of the synchronous belt 36 drives the material receiving cylinder 33 to move back and forth between the material falling port 2121 and the pressing assembly 4. The plate body 31 is vertically arranged inside the machine body 1. The guide rail 32 and the pulley assembly 35 are both fixedly installed on the plate body 31. The power control member 34 provides power to drive the synchronous belt 36 to move along the pulley assembly 35. The material receiving cylinder 33 and the power unit 342 connected with the synchronous belt 36 through the connecting piece 311 slide on the guide rail 32 together, so that the material receiving cylinder 33 moves back and forth between the material falling port 2121 and the pressing assembly 4. The power unit 342 is set as a lifting cylinder for controlling the up and down movement of the material receiving cylinder 33 to be close to the material falling port 2121 and the pressing assembly 4.

[0064] It should be noted that the power control member 34 is a second stepping servo motor 341 and a power unit 342. The power unit 342 is set as a lifting cylinder. The second stepping servo motor 341 is used to provide power to drive the pulley assembly 35 and then drive the material receiving cylinder 33 and the lifting cylinder to move. The pulley assembly 35 includes a tension pulley group 351 and an idler pulley group 352. The tension pulley group 351 is used to tension the synchronous belt 36 to make the synchronous belt 36 in a T shape. The idler pulley group 352 is respectively arranged at both ends of the guide rail 32. The synchronous belt 36 is set as a T-shaped synchronous belt 36. The synchronous belt 36 is sleeved on the idler pulley groups 352 at both ends and is connected to the driving end of the second stepping servo motor 341 downward after passing through the tension pulley group 351.

[0065] Specifically, asFigure 4 As shown, the bead receiving cylinder 33 is provided with a telescopic lever, which cooperates with the bead receiving hole 331 to receive and place the beads. The bead receiving cylinder 33 picks up the beads falling from the blanking port 2121 through the bead receiving hole 331 and fixes them. The telescopic cylinder rod 332 extends to clamp the beads when the bead receiving cylinder 33 picks up the beads. When the bead receiving cylinder 33 moves to the pressing assembly 4, the bead receiving cylinder 33 retracts the cylinder rod 332 to place the beads on the pressing assembly 4.

[0066] Preferably, as Figure 5 shown, the pressing assembly 4 includes a bracket 41 disposed in the machine body 1, a control unit 42 installed on the bracket 41, a pressing head 43 that moves vertically along the bracket 41 driven by the control unit 42. A pressing block plane is formed on one side of the bracket 41 near the bottom, and the control unit 42 drives the pressing head 43 to move downward to apply pressure to the pressing block plane.

[0067] Specifically, as Figure 5 shown, the pressing assembly 4 further includes a preloading guide rail 44 vertically disposed on the bracket 41, a grinding lead screw 45 connected to the driving end of the control unit 42; a weighing sensor 46 disposed at the bottom of the pressing block plane; a switch bracket 47 formed on the bracket 41 and a transmitter (not shown in the figure) that collects the data obtained by the weighing sensor 46. The pressing head 43 is connected to the grinding lead screw 45, and the pressing head 43 slides vertically along the preloading guide rail 44 to the pressing block plane. The data is collected by the weighing sensor 46 and transmitted to the transmitter for measuring the strength of the beads. The bracket 41 is vertically disposed in the machine body 1, and the driving unit is located at the top of the bracket 41. The driving unit is set as a stepping servo motor, the driving end of the stepping servo motor is connected to the grinding lead screw 45, the bottom of the grinding lead screw 45 is connected to the pressing head 43, the preloading guide rail 44 is vertically fixed on the bracket 41, and the pressing head 43 moves downward along the preloading guide rail 44 to apply pressure to the beads placed on the pressing block platform by the bead receiving cylinder 33. The weighing sensor 46 located at the bottom of the pressing block platform collects the data, records the pressure curve and transmits it to the transmitter, and the transmitter transmits the data to the upper computer through a specified protocol.

[0068] Specifically, as Figure 6 shown, it further includes an industrial host computer assembly 5 disposed on the machine body 1. The industrial host computer assembly 5 includes a computer bracket 52 installed on the machine body 1 and an industrial computer 51 disposed on the computer bracket 52. The computer bracket 52 is provided with an adjustment handle 521 for adjusting the pitching angle. When the pressing assembly 4 measures the beads, the weighing sensor 46 collects the data, records the pressure curve and transmits it to the transmitter. The transmitter transmits the data to the upper computer through a specified protocol. The upper computer completes the data processing through the large model processing data system and displays it item by item on the industrial computer 51. This bead particle strength measuring instrument can be equipped with a fully automatic thermal printer, supporting data printing and USB interface data output.

[0069] Combination Figures 1 to 6 As shown in the figure, the present utility model also provides a method for using the above-mentioned bursting bead particle strength measuring instrument, including the following steps:

[0070] Step S1: Place the bursting beads to be measured into the corresponding hopper tray 21 according to the corresponding specifications. After setting the corresponding parameters, start the instrument. The driving component 22 drives the hopper tray 21 to rotate. When the leakage hole 2131 corresponds to the blanking port 2121, the bursting beads fall from the blanking port 2121 to complete the sampling operation;

[0071] Step S2: The receiving cylinder 33 reaches the position of the blanking port 2121, and the bursting beads fall into the receiving port. The power control member 34 drives the receiving cylinder 33 to move to the pressing block plane. The receiving cylinder 33 retracts the lever to place the bursting beads on the pressing block plane, and the receiving cylinder 33 returns to the position of the blanking port 2121 to complete the conveying and distributing operation;

[0072] Step S3: The control unit 42 controls the grinding lead screw 45 to drive the pressure head 43 downward to press the bursting beads located on the pressing block plane. The weighing sensor 46 collects data and transmits it to the transmitter. The transmitter transmits the data to the upper computer. The upper computer completes data processing through the model processing data system and displays the items through the industrial computer 51 to complete the pressure measurement operation.

[0073] Working principle:

[0074] As Figures 1 to 6As shown in the figure, when the bead strength measuring instrument is in use, the measuring personnel only need to place the bead to be measured into the corresponding hopper tray 21 according to the corresponding specifications, then check the brand, set the corresponding parameters, and click the start button. The bead strength measuring instrument will automatically measure. The first stepping servo motor 221 connected to the hopper tray 21 rotates, drives the rotating shaft 224 through the rigid coupling 223, and drives the material distributing plate 213 to rotate. During the rotation, the beads fall into the material leakage holes 2131. When the material leakage holes 2131 correspond to the material dropping ports 2121 on the chassis 212, a sampling action is completed. The beads fall into the material receiving holes 331 on the material receiving cylinder 33 waiting at the designated position. The second stepping servo motor 341 rotates through the control instruction of the upper computer and moves through the movement of the T-shaped synchronous belt 36. A connecting piece 311 is arranged above the synchronous belt 36 to drive the lifting cylinder and the material receiving cylinder 33 to move above the pressing block plane of the pressing mechanism. The lifting cylinder descends to reduce the gap between the material receiving cylinder 33 and the pressing block plane. The material receiving cylinder 33 retracts the cylinder rod 332 to release the bead and place it on the pressing plane 411. Then the lifting cylinder ascends to drive the material receiving cylinder 33 away from the pressing block plane. The material receiving cylinder 33 moves to the waiting position below the material dropping port 2121 of the hopper tray 21, waiting for the next instruction. After the beads are transported to the pressing block plane through the conveying and material distributing assembly 3, the control unit 42 obtains the instruction from the upper computer and drives the pressing head 43 to press downward through the grinding lead screw 45. The weighing sensor 46 collects data, records the pressure curve and transmits it to the transmitter. The transmitter transmits the data to the upper computer through the specified protocol. The upper computer completes the data processing through the large model processing data system and displays it item by item on the industrial computer 51.

[0075] As described above, it is only the preferred embodiment of the present invention, and there is no limitation to the present invention in any form. Those skilled in the art make some simple modifications, equivalent changes or decorations using the disclosed technical content above, and all fall within the protection scope of the present invention.
