Description

Technical Field

[0001] The invention relates to the technical field of fireworks and firecrackers production devices, and more specifically to a forward and reverse bidirectional synchronous rolling fireworks and firecrackers medicine mixing and screening device. Background Art

[0002] Fireworks and firecrackers need to stir the explosives during the production process. For example, the existing publication number is CN217646328U, and the name is an explosives mixer for fireworks and firecrackers. When in use, a person starts the motor. When the motor rotates, the stirring rod can stir the explosives through the transmission of the first gear and the second gear. The explosives can be thrown out of the circular hole into the stirring tank through high-speed rotation, which solves the problem that when stirring the explosives, it may not be stirred more evenly due to the excess of explosives, which will cause unnecessary trouble in the process of fireworks manufacturing and cause problems in the overall production efficiency.

[0003] However, the applicant found that the motor and the explosives feeding port in the above-mentioned explosive mixer are both located above the mixing tank, and the distance between the two is relatively close. Since the motor is an electrical device, sparks may be generated during its operation. When explosive powder is added through the feeding port, there is a safety hazard of explosion when the sparks encounter the explosive powder. In addition, due to the provision of a stirring rod, the above-mentioned explosive mixer is not only complex in structure and large in size, which is inconvenient to transport, but also the stirring and mixing effect of the explosive after one stirring by the stirring rod is not very ideal.

[0004] Therefore, how to provide a forward and reverse bidirectional synchronous rolling fireworks and firecrackers medicine mixing and screening device that is safe to use, simple in structure, small in size, easy to transport, and has good stirring effect is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides a forward and reverse bidirectional synchronous rolling fireworks and firecrackers medicine mixing and screening device which is safe to use, simple in structure, small in size, easy to transport and has good stirring effect.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] The invention discloses a forward and reverse bidirectional synchronous rolling fireworks and firecrackers medicine mixing and screening device, comprising:

[0008] Driving parts;

[0009] An inner rotating shaft, one end of which is fixedly connected to the driving member, and a first bevel gear is sleeved on the inner rotating shaft;

[0010] An outer rotating shaft, the outer rotating shaft is sleeved on the inner rotating shaft, and a second bevel gear is sleeved on the outer rotating shaft;

[0011] A first outer sleeve, wherein the first outer sleeve is sleeved on the outer shaft, a support is fixed on the first outer sleeve, an intermediate shaft is arranged on the support, an intermediate bevel gear is sleeved on one end of the intermediate shaft, and the intermediate bevel gear is meshed and transmission-connected with the first bevel gear and the second bevel gear;

[0012] An inner screen barrel, wherein the inner screen barrel is fixedly connected to the shaft end of the inner rotating shaft away from the driving member, the inner space of the inner screen barrel is a primary mixing chamber, a plurality of screen holes connected to the primary mixing chamber are arranged on the barrel wall of the inner screen barrel, and a first feed port connected to the primary mixing chamber is arranged on one side of the inner screen barrel;

[0013] An outer sieve barrel, the outer sieve barrel is covered on the outside of the inner sieve barrel, and the gap between the two forms a secondary mixing chamber, the outer sieve barrel is fixedly connected to the shaft end of the outer rotating shaft away from the driving member, a plurality of discharge holes connected to the secondary mixing chamber are provided on the barrel wall of the outer sieve barrel, and a second feed port connected to the secondary mixing chamber is provided on one side of the outer sieve barrel, and the second feed port is arranged corresponding to the position of the first feed port;

[0014] Wherein, the inner screen barrel and the outer screen barrel rotate in opposite directions.

[0015] It can be known from the above technical scheme that compared with the prior art, the present invention discloses a forward and reverse bidirectional synchronous rolling fireworks and firecrackers medicine mixing and screening device. When in use, the explosive is put into the primary mixing chamber of the inner screen barrel through the second feeding port and the first feeding port, and the driving member drives the inner rotating shaft to rotate in the first direction, thereby causing the inner screen barrel to rotate in the first direction, and the explosive is continuously rolled up and down and mixed in the primary mixing chamber. At the same time, the first bevel gear on the inner rotating shaft drives the middle bevel gear to rotate, and the middle bevel gear drives the second bevel gear to rotate, thereby causing the outer rotating shaft to rotate in the second direction (whose direction is opposite to the first direction), thereby causing the outer screen barrel to rotate in the second direction. In this way, the transmission through the bevel gear can make the rotation direction of the outer screen barrel opposite to that of the inner screen barrel, that is, the inner screen barrel and the outer screen barrel are synchronously rolled forward and reversely, so that when the explosive stirred in the primary mixing chamber enters the secondary mixing chamber through the sieve hole, the explosive can be continuously rolled and mixed again in the secondary mixing chamber, thereby realizing the secondary mixing, stirring and screening of the explosive, and finally the evenly stirred explosive is discharged through the discharge hole.

[0016] Therefore, the device uses a single driving component to synchronously drive the nested inner and outer sieve barrels to rotate in both forward and reverse directions, which not only makes the overall structure simple, small in size, and easy to transport, but also can realize two synchronous stirring and screening of explosives, which not only improves the uniformity of explosive stirring, but also the sieve holes and discharge holes can perform secondary (or double) screening of larger impurities or larger material particles in the explosives, greatly reducing the degree of impurities in the explosives and improving the explosion effect.

[0017] Furthermore, the driving member includes:

[0018] Pedestal;

[0019] A driving motor is fixed on the base, and an output shaft of the driving motor is fixedly connected to one end of the inner rotating shaft; or, the inner rotating shaft is rotatably arranged on the base, and the driving member is a rotating wheel, and the rotating wheel is fixedly connected to one end of the inner rotating shaft.

[0020] The beneficial effects of adopting the above technical solution are: the device can automatically drive the inner rotating shaft to rotate through the driving motor to realize the automatic driving of the inner sieve barrel and the outer sieve barrel, without manual participation, improving production safety and the degree of automation of the device, and reducing labor costs. Moreover, the driving motor of the device is connected to the inner sieve barrel through a longer inner rotating shaft, so that the distance between the feed port and the driving motor is increased, which can reduce the probability of explosive powder floating to the position of the driving motor and reduce the risk of explosion. Of course, the device can also use a rotating wheel to manually drive the inner rotating shaft to rotate, so as to realize the manual driving of the inner sieve barrel and the outer sieve barrel. This manual driving method is safer to use, but it is more suitable for small batches of explosives mixing, screening operations, or as an experimental tool.

[0021] Furthermore, the first outer sleeve is fixedly connected to the base via a support rod.

[0022] The beneficial effect of adopting the above technical solution is: supporting the device to prevent the device from collapsing.

[0023] Furthermore, the support member includes:

[0024] A supporting connecting rod, one end of which is fixedly connected to the wall of the first outer sleeve;

[0025] The second outer sleeve has a wall fixedly connected to the other end of the supporting connecting rod, and the second outer sleeve is sleeved on the intermediate rotating shaft.

[0026] The beneficial effect of adopting the above technical solution is: the intermediate rotating shaft can be placed between the first bevel gear and the second bevel gear through the support member, so that the intermediate bevel gear can be synchronously meshed and connected with the first bevel gear and the second bevel gear, so that the inner rotating shaft can synchronously drive the outer rotating shaft to rotate in the clockwise and counterclockwise directions, and finally the inner screen barrel and the outer screen barrel can be synchronously rotated in the clockwise and counterclockwise directions to achieve the effect of secondary stirring and screening mixing uniformity of the explosives.

[0027] Furthermore, bearings are provided between the first outer sleeve and the outer rotating shaft, and between the second outer sleeve and the intermediate rotating shaft.

[0028] The beneficial effect of adopting the above technical solution is: improving the smoothness of the rotation of the outer rotating shaft and the intermediate rotating shaft.

[0029] Furthermore, a bearing is provided between the inner rotating shaft and the outer rotating shaft.

[0030] The beneficial effect of adopting the above technical solution is: improving the rotation smoothness between the inner rotating shaft and the outer rotating shaft.

[0031] Furthermore, a bearing is provided between the outer sieve barrel and the inner rotating shaft.

[0032] The beneficial effect of adopting the above technical solution is: improving the rotation smoothness between the outer screen barrel and the inner rotating shaft, avoiding the danger of sparks caused by frictional rotation.

[0033] Furthermore, the outer sieve barrel and the inner sieve barrel are both flat waist-drum shaped, and a plurality of discharge holes are provided at the waist-drum position of the outer sieve barrel.

[0034] The beneficial effect of adopting the above technical solution is that both the inner sieve barrel and the outer sieve barrel are flat waist drum-shaped, so that they are small in size, light in weight and easy to transport. BRIEF DESCRIPTION OF THE DRAWINGS
