Description

Technical Field

[0001] This utility model relates to the field of tobacco processing machinery technology, and in particular to a nozzle positioning device. Background Technology

[0002] Currently, domestic tobacco companies generally use rehumidifiers, which heat and humidify materials through nozzles. Generally, steam is used to atomize water to form water atomized particles, which are then evenly sprayed onto the surface of tobacco leaves to achieve the purpose of heating and humidifying the tobacco leaves.

[0003] The nozzle used in the tobacco rehumidifier is a dual-media nozzle, mainly composed of a ejector pin 1, an ejector pin sleeve 2, a nozzle body 3, a clamping sleeve, and a fixing bracket 7. The nozzle body 3 has a steam inlet 31 and a water inlet 32. There is a gap between the ejector pin 1 and the ejector pin sleeve 2, and also a gap between the ejector pin sleeve 2 and the nozzle body 3. Water is ejected from the gap between the ejector pin 1 and the ejector pin sleeve 2 in an umbrella shape. Steam is ejected from the gap between the ejector pin sleeve 2 and the nozzle body 3, atomizing the water.

[0004] Since the main internal structure of the nozzle consists of the ejector pin 1 and the ejector pin sleeve 2, the gap between them determines the umbrella-like shape of the steam and water ejected from the nozzle. A reasonable gap can achieve a good umbrella-like shape and atomization effect, while an unreasonable gap often results in poor atomization. However, in the existing technology, the gap between the ejector pin 1 and the ejector pin sleeve 2 inside the nozzle is adjusted manually based on experience, which has a large error margin, and since each person's skill level is different, it often leads to poor nozzle atomization effect; at the same time, manual adjustment is time-consuming and inefficient.

[0005] Therefore, there is an urgent need for a nozzle positioning device to solve the above-mentioned technical problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] like Figure 1 As shown, this utility model relates to a nozzle positioning device. The nozzle positioning device is used to position a nozzle. The nozzle includes a ejector pin 1, an ejector pin sleeve 2, and a nozzle body 3. The ejector pin 1 passes through the ejector pin sleeve 2, and the ejector pin sleeve 2 passes through the nozzle body 3. The nozzle positioning device includes a mounting member 4 and a positioning member 5. The mounting member 4 is connected to the nozzle body 3, and the positioning member 5 is mounted on the mounting member 4.

[0032] Specifically, such as Figure 1 and Figure 2As shown, the positioning component 5 is provided with a first positioning surface 511 and a second positioning surface 521. The first positioning surface 511 can abut against the ejector pin 1, and the second positioning surface 521 can abut against the ejector pin sleeve 2, so that the distance between the ejector pin 1 and the ejector pin sleeve 2 and the distance between the ejector pin sleeve 2 and the nozzle body 3 reach preset values. This nozzle positioning device allows for nozzle adjustment, enabling precise setting of preset values ​​for the distance between the ejector pin 1 and the ejector pin sleeve 2 and the distance between the ejector pin sleeve 2 and the nozzle body 3. Compared to existing technologies, this reduces errors from manual adjustment, maintains good spraying performance, shortens adjustment time, and improves adjustment efficiency.

[0033] Preferably, such as Figure 3 As shown, the positioning component 5 includes a first positioning post 51 and a second positioning post 52. The diameter of the first positioning post 51 is smaller than the diameter of the second positioning post 52. The first positioning post 51 is installed on the end face of the second positioning post 52, and the first positioning post 51 and the second positioning post 52 are coaxially arranged. The end face of the first positioning post 51 is the first positioning surface 511, and the end face of the second positioning post 52 on the outer periphery of the first positioning surface 511 is the second positioning surface 521. The other end face of the second positioning post 52 is connected to the mounting component 4. Specifically, in this embodiment, the positioning element 5 consists of a first positioning post 51 and a second positioning post 52. The diameter of the first positioning post 51 is larger than the diameter of the outlet end of the ejector pin 1, and smaller than the diameter of the outlet end of the ejector pin sleeve 2, so that the ejector pin 1 can abut against the end face of the first positioning post 51, and the first positioning post 51 is not affected by the ejector pin sleeve 2. The diameter of the second positioning post 52 is larger than the diameter of the outlet end of the ejector pin sleeve 2, and smaller than the diameter of the outlet end of the nozzle body 3, so that the ejector pin sleeve 2 can abut against the end face of the second positioning post 52, and the second positioning post 52 is not affected by the nozzle body 3. The second positioning post and the mounting element... 4. Fixed connection to prevent the second positioning post 52 from moving; the first positioning post 51 and the second positioning post 52 are coaxially fixedly connected. The end face of the first positioning post 51 is the first positioning surface 511, and the end face of the second positioning post 52 on the outer periphery of the first positioning surface 511 is the second positioning surface 521. When the operator needs to adjust the distance between the ejector pin 1 and the ejector pin sleeve 2 and the distance between the ejector pin sleeve 2 and the nozzle body 3, the ejector pin 1 abuts against the first positioning surface 511, and the ejector pin sleeve 2 abuts against the second positioning surface 521. This allows the distance between the ejector pin 1 and the ejector pin sleeve 2 and the distance between the ejector pin sleeve 2 and the nozzle body 3 to reach the preset value, which is convenient and quick, and ensures that the nozzle maintains a good spraying effect. Of course, in some other embodiments, the structure of the positioning member 5 can be of any shape, and the abutting surfaces can be partially abutted or completely abutted, as long as the positioning of the ejector pin 1 and the ejector pin sleeve 2 is not affected. This will not be elaborated further here.

[0034] Optionally, the first positioning post 51 and the second positioning post 52 are integrated into one piece, which can increase the overall strength of the positioning component 5, prevent the first positioning post 51 and the second positioning post 52 from moving relative to each other, and ensure the accuracy of positioning of the ejector pin 1 and the ejector pin sleeve 2.

[0035] Preferably, such as Figures 1 to 4 As shown, the mounting component 4 is provided with a first mounting portion 41, which has an internal thread and can be threadedly connected to the nozzle body 3. Specifically, in this embodiment, the mounting component 4 is a sleeve with a first mounting portion 41 and an internal thread, which can be threadedly connected to the nozzle body 3, facilitating the installation and removal of the mounting component 4. Simultaneously, by coaxially aligning the mounting component 4 with the nozzle body 3, the ejector pin 1 and ejector pin sleeve 2 can be aligned with the positioning component 5, thereby ensuring accurate positioning of the ejector pin 1 and ejector pin sleeve 2. Of course, in other embodiments, the structure of the mounting component 4 can be other shapes, and the mounting component 4 and the nozzle body 3 can be connected by a snap-fit ​​mechanism, which will not be elaborated here.

[0036] Optionally, the outer periphery of the first mounting portion 41 is configured as a hexagonal structure. Specifically, in this embodiment, the outer periphery of the first mounting portion 41 is configured as a hexagonal structure, which can be gripped by a wrench, making it convenient for workers to install the first mounting portion 41 onto the nozzle body 3. Of course, in some other embodiments, the outer periphery of the first mounting portion 41 can be configured with other structures that facilitate wrench operation.

[0037] Preferably, the mounting component 4 is further provided with a second mounting part 42, which is mounted at one end of the first mounting part 41, and the second mounting part 42 is provided with an observation window 421. Specifically, the mounting component 4 also has a second mounting part 42, which is used to mount the positioning component 5. The second mounting part 42 is connected to the first mounting part 41, and the second mounting part 42 is provided with an observation window 421, through which the operator can observe the contact between the ejector pin 1 and the ejector pin sleeve 2 and the positioning component 5, ensuring that the ejector pin 1 and the ejector pin sleeve 2 abut against the positioning component 5.

[0038] Optionally, the second mounting portion 42 is provided with a plurality of observation windows 421, which are evenly distributed along the circumference of the second mounting portion 42. Specifically, in order to fully observe the contact between the ejector pin 1 and the ejector sleeve 2 and the positioning member 5, a plurality of observation windows 421 are evenly arranged along the circumference of the second mounting portion 42, which allows the operator to fully observe the contact between the ejector pin 1 and the ejector sleeve 2 and the positioning member 5, and prevents the ejector pin 1 and the ejector sleeve 2 from tilting.

[0039] Preferably, the nozzle positioning device further includes a fixing member 6, and the second mounting part 42 is provided with a fixing hole 422. The fixing member 6 can pass through the fixing hole 422 to connect the positioning member 5 to the second mounting part 42. Specifically, the nozzle positioning device is provided with a fixing member 6, and one end of the second mounting part 42 has a fixing hole 422. The fixing member 6 can pass through the fixing hole 422 and be detachably connected to the positioning member 5. By detachably connecting the fixing member 6 and the positioning member 5, different models of positioning members 5 can be replaced, thereby changing the distance between the ejector pin 1 and the ejector pin sleeve 2 and the distance between the ejector pin sleeve 2 and the nozzle body 3, thus obtaining different spray effects.

[0040] Optionally, the positioning element 5 is provided with a threaded hole 522, and the fixing element 6 can pass through the fixing hole 422 and be threadedly connected to the positioning element 5. Specifically, in this embodiment, the second positioning post 52 is provided with a threaded hole 522, and the fixing element 6 is a bolt. The fixing element 6 can pass through the fixing hole 422 and be threadedly connected to the second positioning post 52, which facilitates the replacement of the positioning element 5.

[0041] Preferably, the nozzle positioning device further includes a gasket disposed between the fixing member 6 and the second mounting portion 42. Specifically, in order to prevent the positioning member 5 from loosening, a gasket is provided between the fixing member 6 and the second mounting portion 42. The fixing member 6 passes through the gasket and the fixing hole 422 and is connected to the second positioning post 52, which can prevent the fixing member 6 from loosening with the positioning member 5.

[0042] Preferably, both the mounting component 4 and the positioning component 5 are made of steel. Specifically, the mounting component 4 and the positioning component 5 are made of stainless steel. Since liquid often remains inside the nozzle, it will flow onto the mounting component 4 and the positioning component 5 when adjusting the nozzle. To prevent the mounting component 4 and the positioning component 5 from rusting, using stainless steel for them can improve their service life, thereby improving the service life of the nozzle positioning device.

[0043] This utility model provides a nozzle positioning device that can position the ejector pin 1 and the ejector pin sleeve 2, ensuring that the distance between the ejector pin 1 and the ejector pin sleeve 2, and the distance between the ejector pin sleeve 2 and the nozzle body 3, reach preset values, thereby guaranteeing the spraying effect. The usage process of this device is as follows:

[0044] (1) Check the nozzle atomization effect. When it is necessary to readjust the nozzle atomization effect, use pipe wrenches to remove the nozzle clamping sleeve.

[0045] (2) Adjust the locking sleeve at the rear of the nozzle, loosen the ejector pin 1 and ejector pin sleeve 2, and screw them back to ensure that the nozzle and nozzle sleeve have enough space for the nozzle positioning device to be installed.

[0046] (3) Screw the first mounting part 41 of the nozzle positioning device into the nozzle thread, and tighten the first mounting part 41 with a hex wrench. Through the observation window 421, observe that the inside of the nozzle positioning device is completely pressed against the head of the nozzle.

[0047] (4) Twist the ejector pin 1 and ejector sleeve 2 forward until they can no longer be turned. At this time, the ejector pin 1 and ejector sleeve 2 will press against the first positioning surface 511 and the second positioning surface 521 of the nozzle positioning device.

[0048] (5) Tighten the locking sleeve at the end of the nozzle to fix the ejector pin 1 and ejector pin sleeve 2, disassemble the device and install the clamping sleeve.
