Description
Technical Field
[0001] The utility model relates to the technical field of fireworks, in particular to a fireworks inner tube powder mixing device. Background Art
[0002] Fireworks are entertainment items that use pyrotechnic powder as raw materials and are used to produce effects such as sound, light, color, shape, and smoke. The process of loading the inner tube of fireworks has become the risk point with the highest probability of accidents in fireworks production. The fundamental reason is that the explosive powder used in fireworks production is much more sensitive to friction, impact, static sparks, heat, etc. than other pyrotechnic powders.
[0003] In order to solve the problem of high risk of charging in the inner tube of fireworks, a production technology is proposed, which is to first add the required oxidant, reductant and fireworks effect parts into the inner tube of the fireworks, and then mechanically shake the oxidant and reductant to mix into the required bursting charge in the inner tube of the fireworks, while the effect parts are evenly dispersed in the inner tube. This replaces the traditional production process of first mechanically mixing to make the bursting charge, and then manually loading the bursting charge and effect parts into the inner tube of the fireworks, effectively reducing the safety risks of the bursting charge during the preparation, transportation and loading of the bursting charge.
[0004] However, the current method of mixing drugs adopts the method of filling the drugs into the drug cake and mixing the drugs by shaking the drug cake left and right. The outstanding problem of this mixing method is that the shaking or shaking left and right action principle is unreasonable, and its movement trajectory determines that the mixing is insufficient and uneven. In addition, the movement degree of this movement method affects the mixing effect. A drug cake needs to be mixed by several mixing devices set up in sequence for continuous operation, which is difficult to meet the product design requirements. It not only increases the site requirements and investment costs, but also cannot meet the normal production needs of the enterprise; in particular, the work efficiency is low, which affects the normal production and operation of other processes, and the production efficiency is low, resulting in corresponding high production costs.

DETAILED DESCRIPTION
[0015] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

It uses a certain shaking frequency and stroke to form a certain angle along the axial direction of the inner cylinder to perform reciprocating linear shaking motion, and can use the irregular vibration generated by the direction change process in the reciprocating linear shaking motion, combined with the speed difference and inertia of the inner cylinder and the medicine in it during the back and forth process of the reciprocating linear shaking motion, so that the various materials in the inner cylinder form irregular shaking oscillations and tumbling, thereby achieving the purpose of fully and quickly mixing, and obtaining better medicine mixing effect and higher medicine mixing production efficiency.
[0017] The firework inner tube powder mixing device of the present invention comprises a conveyor or a workbench arranged on a bracket, and a mixing component etc. arranged on the bracket 401 corresponding to the workbench 402.
[0018] The first embodiment of the utility model
[0019] like Figure 1 and 2 As shown, in the first embodiment of the utility model, the mixing assembly 4 includes a clamping device, a shaking device, and the like.
[0020] The clamping device includes a clamping plate 411, a sealing plate 408, a movable connecting frame 409, and corresponding clamps connected to the clamping plate 411 and the sealing plate 408 through the movable connecting frame 409. The shaking device includes a telescopic shaker 403, and a telescopic reciprocating motion guide device. The clamp provided on the clamping plate is composed of two clamping cylinders 410, the clamp provided on the sealing plate 408 is composed of a sealing cylinder 413, and the telescopic shaker is composed of a shaking cylinder 403. The movable connecting frame is a gantry-type movable connecting frame 409.
[0021] The clamping plate includes two movable clamping plates 411 corresponding to opposite sides of the medicine cake 100 respectively, and the sealing plate 408 is arranged corresponding to the corresponding upper end surface of the medicine cake 100 or its inner tube 1001.
[0022] One end of the piston rod of the two clamping cylinders 410 arranged radially or transversely is respectively connected to the two movable clamping plates 411, and one end of the cylinder body of the other end of the two clamping cylinders 410 arranged radially or transversely is respectively fixedly connected to the opposite sides of the movable connecting frame 409. The radial and axial directions are arranged relative to the axis of the medicine cake or the inner cylinder therein.
[0023] One end of the axially arranged pressure-sealing cylinder 413 is fixedly connected to the pressure-sealing plate 408 , and the other end of the pressure-sealing cylinder 413 is fixedly connected to the top edge of the movable connecting frame 409 .
[0024] The telescopic reciprocating motion guide device of the shaking and mixing device includes four guide pillars 405, one end of which is respectively fixedly connected to the pressure sealing plate 408, and guide sleeves 406, etc. The other end of the guide pillars 405 is connected to the connecting plate 404, and each guide sleeve 406 is respectively sleeved on each guide pillar 405. The guide sleeve 406 can be fixedly connected to the bracket 401 through the mounting plate 407. One end of the shaking cylinder 403 is fixedly connected to the connecting plate 404, and the other end of the shaking cylinder 403 can be fixedly connected to the mounting plate 407, and the mounting plate 407 can be fixed to the wall under the workbench or the corresponding part of the bracket.
[0025] During operation, the medicine cake 100 is placed on the workbench 402 below the sealing plate 408, and the corresponding controller controls the start of the two clamping cylinders 410 to extend toward each other, driving the two movable clamping plates 411 to move toward each other until the medicine cake is clamped. When the clamping cylinder 410 is in place, the controller controls the sealing cylinder 413 to start, and the sealing cylinder 413 extends, driving the movable connecting frame 409 and the sealing plate 408 to move back to back, and the upper end of the medicine cake 100 clamped on the movable connecting frame 409 and on the workbench below the sealing plate and the anti-static rubber sealing pad on the lower wall of the sealing plate 408a are pressed against each other, so that the medicine loading ports of each inner cylinder of the medicine cake 100 are sealed by the antistatic rubber sealing pad, the controller controls the pressure sealing cylinder 413 to maintain, and at the same time controls the start of the shaking cylinder 403 to do up and down reciprocating motion at a higher frequency, and the connecting plate 404 connected to the piston rod end of one end of the shaking cylinder 403 drives the guide post 405 to slide up and down on the guide sleeve 406, so that the pressure sealing plate 408 connected to the other end of the guide post 405 and the clamped medicine cake 100 do up and down reciprocating shaking vibration, thereby making the medicine in the inner cylinder shake + vibrate + tumble evenly and quickly mix. Its shaking motion direction is the same as the inner cylinder axis, and is in the up and down direction. The lower limit of the stroke of the shaking cylinder can be based on touching the work surface or not touching the work surface. The stroke height is determined in combination with the shaking frequency, or determined by experiment, and this example can be 30-80cm.
[0026] The shaking cylinder of the utility model is a high-frequency cylinder, and its working frequency can be determined according to the actual mixing effect. The duration of shaking mixing by the shaking cylinder moving up and down can be determined by experiments according to different products, generally only 2-10s, and the interval between the medicine cake on the workbench and the sealing plate is small in the initial state.
[0027] Second embodiment
[0028] like Figure 3 As shown, the telescopic shaker of the shaking mixing device includes a shaking air motor 423 mounted on a bracket or its mounting plate 407, a rotating arm 421, and a telescopic output rod 425. The telescopic output rod 425 can be slidably sleeved on a connecting sleeve 424, and the connecting sleeve 424 is fixedly connected to the mounting plate 407. One end of the rotating arm 421 is fixedly connected to the output shaft of the shaking air motor 423. One end of the telescopic output rod 425 and the other end of the rotating arm 421 are movably hinged to each other through a swing rod 422. The other end of the telescopic output rod 425 is movably or fixedly connected to the connecting plate 404.
[0029] When the shaking and mixing device is working, the rotation of the output shaft of the shaking pneumatic motor 423 drives the rotating arm 421 to rotate, and the rotational motion of the rotating arm 421 is converted into a retractable output rod under the limit guide of the connecting sleeve 424 through the transmission of the swing rod 422 to perform reciprocating linear motion. Its reciprocating linear motion drives the guide column 405 to slide up and down on the guide sleeve 406 through the connecting plate 404, so that the pressure sealing plate 408 connected to the other end of the guide column 405 and the clamped medicine cake 100 perform up and down shaking and vibration motion, thereby making the medicine in the inner tube of the medicine cake shake + vibrate + tumble evenly, fully and quickly mixed. On the basis of ensuring safe and reliable operation, this example can obtain a wider medicine cake shaking speed through the higher movement frequency of the pneumatic motor to obtain a higher shaking frequency, further improving the mixing effect and production efficiency. The remaining components, connection structures and corresponding operating principles and modes of this example are similar to those of the above-mentioned embodiment 1.
[0030] In the third embodiment, the vibrator is a motor. The rest of the components, connection structure and corresponding operation principle of this embodiment are similar to those of the second embodiment.
[0031] The fourth embodiment, as Figure 4 and 5 Shown
[0032] In this example, the clamping plate of the clamping device includes a movable clamping plate 411 and a fixed clamping plate 411a respectively arranged on opposite sides of the medicine cake, the fixed clamping plate 411a is fixed to the inner wall surface of one side of the pressure sealing plate 408, and the movable clamping plate 411 is connected to the other side of the pressure sealing plate 408 through the clamping cylinder 410. During operation, the movable clamping plate 411 moves toward the fixed clamping plate 411a under the control of the clamping cylinder 410, and then the medicine cake 100 is pressed by the fixed and movable clamping plates. During specific installation, the movable clamping plate 411 can be connected to one end of the piston rod 410a of the clamping cylinder 410, and the cylinder body of the movable clamping plate can be fixedly connected to the corresponding side of the pressure sealing plate 408.
[0033] In this example, the shaking device only includes a shaker, and the shaker is only composed of a shaking cylinder 403 connected between the pressure sealing plate 408 and the bracket 401. One end of the cylinder body of the shaking cylinder 403 can be fixed on the bracket 401, and one end of the piston rod 403a of the shaking cylinder 403 is connected to the top edge of the pressure sealing plate 408. When specifically connected, the pressure sealing plate 408 constitutes a multifunctional movable frame component, and the shaking cylinder 403 also plays a multifunctional role of pressing and sealing the pressure sealing plate 408 and reciprocating telescopic shaking motion.
[0034] During operation, the medicine cake 100 is placed on the workbench 402 against the side wall of the fixed clamping plate 411a. The controller first starts the shaking cylinder 403, and first controls the shaking cylinder 403 to extend slightly so that the sealing plate 408 can press the medicine cake 100 into place. The controller then controls the clamping cylinder 410 to work, so that the movable clamping plate 411 moves to the side of the fixed clamping plate 411a to cooperate with the fixed clamping plate 411a to clamp the medicine cake into place. The controller then starts the shaking cylinder 403 to perform corresponding up and down telescopic reciprocating motion with a set stroke. The shaking cylinder 403 drives the sealing plate 408 and the medicine cake 100 to shake and vibrate up and down, and mix the medicine in the inner cylinder for a certain period of time. The structural principle of the medicine mixing in this example is relatively simple, reasonable, and energy-saving. It has high operational reliability, small maintenance and repair, and low construction cost.
[0035] Since the moving distance of the movable clamping plate is small, when the movable clamping plate moves and clamps the medicine cake, it utilizes the twisting deformation effect of the anti-static rubber sealing pad 408a of a certain thickness in the moving direction (i.e. the width or length direction of the anti-static rubber sealing pad), and its clamping device can reliably and stably clamp the clamped and sealed medicine cake.
[0036] The remaining components, connection structures and corresponding operating principles of this example are similar to those of any of the above embodiments.
[0037] For the utility model, the setting height of the fixed clamping plate and the movable clamping plate can be less than the corresponding height of the medicine cake, and after the medicine cake is tightly sealed by the sealing plate, the upper and lower end surfaces of the fixed clamping plate 411a and the movable clamping plate 411 can be slightly shorter than the upper and lower end surfaces of the medicine cake.
[0038] In the fifth embodiment, the lower end of the fixed clamping plate is fixedly connected with a convex edge in the form of a sheet that protrudes toward the moving clamping plate. After the sealing plate is pressed and sealed, the convex edge at the lower end of the fixed clamping plate contacts the work surface. During operation, the medicine cake is placed on the side of the work table close to the fixed clamping plate, and the convex edge at the lower end of the fixed clamping plate extends into a part of the bottom surface of the medicine cake. Generally, it can extend 0.5-5cm. It can achieve a stable clamping effect with a relatively small clamping force. The operation method and method of the clamping work of the medicine cake in this example can be similar to those of the above-mentioned third embodiment. The remaining component structure, connection structure and corresponding operation principle and method of this example can be similar to any of the above-mentioned embodiments.
[0039] In the sixth embodiment
[0040] The clamping plate of the clamping device in this example includes two movable clamping plates, which are respectively connected to the opposite sides of the pressure sealing plate 408 through clamping cylinders. That is, on the basis of the above-mentioned embodiment 3, the fixed clamping plates are changed into movable clamping plates.
[0041] During operation, first start the two clamping cylinders 410 to clamp the medicine cake, and then start the shaking cylinder 403 to perform telescopic shaking to mix the medicine. The rest of the corresponding components, connection structures, working principles and operating methods of this example are similar to any of the above-mentioned embodiments. During operation, first start the two clamping cylinders 410 to clamp the medicine cake, and then start the shaking cylinder 403 to perform telescopic shaking to mix the medicine. The rest of the corresponding components, connection structures, working principles and operating methods of this example are similar to any of the above-mentioned embodiments.
[0042] The seventh embodiment Figure 6 and 7 As shown, in this embodiment, the mixing assembly 4 is also connected to a tilting device. The tilting device includes a telescope, and the telescope includes a tilt angle adjustment cylinder 426, etc. The mixing assembly 4 is hinged to the base frame 428 through the tilt angle adjustment cylinder 426 in an angle-adjustable manner, and the support workbench can be fixedly set on a base plate. The angle between the base plate and the base frame 428 is the tilt angle a, and a hinge 427 is connected between one side of the base plate at the bottom of the bracket 401 of the mixing assembly 4 and the corresponding side of the base frame 428, and the two ends of the tilt angle adjustment cylinder 426 are respectively hinged to the other side of the base plate at the bottom of the bracket 401 and the other side of the base frame 428 through the hinge 427.
[0043] During operation, the tilt angle adjustment cylinder 426 is turned on, and the tilt angle adjustment cylinder 426 is extended, so that the mixing assembly 4 set on the support workbench is tilted to one side at an angle a relative to the horizontal plane. In this way, in the waiting state, the shaking and telescopic movement direction of the shaking cylinder 403 is consistent with the axial direction of the inner cylinder, and the inner cylinder is in a tilted state. The material level height of the medicine in the inner cylinder relative to the horizontal plane is different, and the material level on one side is high and the material level on the other side is low. When the shaking cylinder 403 is started to work, it forms a completely different shaking movement mixing mode for the medicine, which has a correspondingly better mixing effect. The tilt angle a can be in the range of 0-90 degrees.
[0044] The remaining components, connection structures and corresponding operating principles of this example are similar to those of any of the above embodiments.
[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
