Description

Technical Field

[0001] This utility model relates to the field of tobacco screening machine technology, and more specifically, to a tobacco screening machine with an easy-to-replace screen. Background Technology

[0002] Vibrating screens operate using reciprocating rotary vibrations generated by vibrators. When a large quantity of loose material of varying sizes and a mixture of coarse and fine particles enters the screen surface, only a portion of the particles come into contact with the screen. Due to the vibration of the screen box, the material layer on the screen is loosened, further widening the gaps between large particles. Small particles then pass through these gaps and are transferred to the lower layer or onto a conveyor. Because the gaps between small particles are small, large particles cannot pass through. Thus, the originally randomly arranged particle group separates, forming stratification according to particle size, resulting in a pattern where small particles are at the bottom and coarse particles are at the top. Fine particles that reach the screen surface, smaller than the screen openings, pass through the screen, ultimately achieving the separation of coarse and fine particles and completing the screening process.

[0003] To meet the screening needs of different materials, the screens of the vibrating screen need to be changed frequently. When changing the screen, the workers need to remove multiple fixing bolts one by one. This step requires a certain amount of time and effort because there are many bolts, and they may be rusted or tightened due to long-term use, which increases the difficulty of disassembly. Only after all the fixing bolts have been successfully removed can the top cover of the machine be removed. Only after the top cover of the machine is successfully removed can the screen inside the machine be accessed and disassembled. In the entire process of changing the screen, the disassembly and installation steps need to be repeated twice. The first disassembly is to remove the old screen, and then a similar operation is required when installing the new screen. This repetitive operation not only increases the labor intensity of the workers, but also greatly reduces the speed of screen replacement.

[0004] Therefore, how to provide a tobacco screening machine with easy screen replacement has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a tobacco screening machine that facilitates screen replacement.

[0006] According to a first aspect of the present invention, a tobacco screening machine that facilitates screen replacement is provided, comprising: a base plate, an elastic support, a vibrating box, a horizontal plate, a screen body, and an installation assembly;

[0007] The elastic brackets are set at the four corners of the base plate and are connected to the bottom of the vibration box. A suction fan is set on the base plate and is connected to the vibration box. An installation port is set on the side wall of the vibration box. The screen body passes through the installation port and is inserted into the interior of the vibration box. The horizontal plate covers the outside of the installation port and is connected to the side wall of the vibration box.

[0008] The first end of the mounting assembly is rotatably connected to the side wall of the vibration box, and the first end of the mounting assembly is connected to the horizontal plate. The mounting assembly is used to fix the horizontal plate.

[0009] Optionally, the mounting assembly includes a limiting plate, a positioning element, a fixing block, and a limiting spring. The limiting plate is movably connected to the side wall of the vibration box via a hinge, and the limiting plate abuts against the horizontal plate. The fixing block is fixed on the horizontal plate and located below the limiting plate. The two ends of the limiting spring are respectively connected to the fixing block and the positioning element. The positioning element is slidably disposed on the horizontal plate and engages with the limiting plate.

[0010] Optionally, the mounting assembly further includes two vertical rods, which are located on both sides of the positioning member. The first end of each vertical rod is connected to the positioning member, and the second end of each vertical rod passes through the fixing block and is slidably connected to the fixing block.

[0011] Optionally, the mounting assembly further includes a push block disposed on the outside of the positioning member.

[0012] Optionally, the horizontal plate is provided with a sliding groove, and the inner sidewall of the positioning member is provided with a slider, which is slidably disposed in the sliding groove.

[0013] Optionally, a pull ring is provided on the right side of the limiting plate.

[0014] Optionally, the horizontal plate is provided with two handles, which are respectively located near both ends of the horizontal plate, and the mounting assembly is located between the two handles.

[0015] Optionally, a reinforcing block is provided between the handle and the cross plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model allows the positioning component to be pulled down, compressing the limiting spring and separating it from the limiting plate. Once the limiting plate is no longer fixed, it can be rotated to separate from the horizontal plate. Pulling the horizontal plate to move it to the right causes the screen body to move to the right, and the screen body exits the vibrating box. During this process, no other parts need to be disassembled. The entire screen replacement process does not require the disassembly of other front-end components, and the screen can be directly disassembled and removed, thus improving the screen replacement speed.

[0018] 2. By setting up installation components, this utility model can fix the screen body, preventing it from loosening during use and causing it to shake, thus improving the screen body's performance.

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] like Figures 1 to 4 As shown, this utility model embodiment provides a tobacco screening machine that facilitates screen replacement, including a base plate 1, an elastic support 2, a vibrating box 3, a horizontal plate 5, a screen body 6, and an installation assembly 7.

[0031] Elastic supports 2 are set at the four corners of the base plate 1 and are connected to the bottom of the vibrating box 3. A suction fan 4 is set on the base plate 1 and is connected to the vibrating box 3. An installation port (not shown in the figure) is set on the side wall of the vibrating box 3. The screen body 6 passes through the installation port and is inserted into the interior of the vibrating box 3. The horizontal plate 5 covers the outside of the installation port and is connected to the side wall of the vibrating box 3.

[0032] Specifically, the horizontal plate 5 is slidably mounted on the mounting opening and moves laterally along the mounting opening.

[0033] The first end of the mounting component 7 is rotatably connected to the side wall of the vibration box 3, and the first end of the mounting component 7 is connected to the horizontal plate 5. The mounting component 7 is used to fix the horizontal plate 5.

[0034] This utility model fixes the screen body 6 by rotatably connecting the first end of the mounting component 7 to the side wall of the vibrating box 3 and connecting the first end of the mounting component 7 to the horizontal plate 5, thereby preventing the screen body 6 from loosening during use and causing the screen body 6 to shake, thus improving the performance of the screen body 6.

[0035] Furthermore, the elastic support 2 includes a fixed housing (not shown in the figure), a support spring (not shown in the figure), and a connecting rod (not shown in the figure). The fixed housing is fixedly installed on the four corners of the base plate 1. The support spring is located inside the fixed housing and is sleeved on the connecting rod. The first end of the connecting rod is provided with a support plate, which is connected to the inner wall of the fixed housing. The first end of the support spring is connected to the support plate, and the second end of the support spring is connected to the top of the inner wall of the fixed housing. Through the cooperation of the support spring and the connecting rod, the effect on the tobacco can be further improved during vibration, and the vibration box 3 can also be stably placed on the base.

[0036] In one embodiment of the tobacco screening machine of this utility model that facilitates screen replacement, such as... Figure 3As shown, the mounting assembly 7 includes a limiting plate 71, a positioning element 72, a fixing block 73, and a limiting spring 74. The limiting plate 71 is movably connected to the side wall of the vibration box 3 via a hinge, and the limiting plate 71 abuts against the horizontal plate 5. The fixing block 73 is fixed on the horizontal plate 5 and located below the limiting plate 71. The two ends of the limiting spring 74 are respectively connected to the fixing block 73 and the positioning element 72. The positioning element 72 is slidably disposed on the horizontal plate 5 and is engaged with the limiting plate 71.

[0037] Specifically, the first end of the limiting plate 71 is rounded, allowing it to rotate smoothly via a hinge. The second end of the limiting plate 71 extends onto the horizontal plate 5 and abuts against the positioning member 72. The positioning member 72 has a vertically placed Z-shaped structure, and its inner wall engages with the second end of the limiting plate 71, thus fixing the limiting plate 71 and preventing the screen body 6 from loosening during use, which would cause the screen body 6 to shake and improve its performance.

[0038] When a screen needs to be replaced, the operator applies force to the positioning element 72, causing it to move downwards. This downward movement compresses the limiting spring 74, separating the positioning element 72 from the limiting plate 71. Once the limiting plate 71 is no longer fixed, the operator can rotate it to separate it from the horizontal plate 5, thus pulling the horizontal plate 5 outwards. The horizontal plate 5 then moves the screen body 6 outwards, allowing it to exit the vibrating box 3. No other components need to be disassembled during this process. The entire screen replacement process does not require disassembling any other components; the screen can be directly removed, improving the screen replacement speed.

[0039] When the screen needs to be installed, the operator applies force to the limiting plate 71, causing it to rotate above the installation opening via a hinge. Then, the operator inserts the screen body 6 into the installation opening. Next, the operator applies force to the positioning member 72, causing it to move downwards. This downward movement compresses the limiting spring 74. At this point, the operator rotates the limiting plate 71, moving it to abut against the horizontal plate 5. Then, the operator releases the force on the positioning member 72, allowing it to return to its initial position under the action of the limiting spring 74. This causes the positioning member 72 to engage with the limiting plate 71, providing both limiting and fixing functions.

[0040] In one embodiment of the tobacco screening machine of this utility model that facilitates screen replacement, such as... Figure 3 As shown, the mounting assembly 7 also includes two vertical rods 8, which are located on both sides of the positioning member 72. The first end of the vertical rod 8 is connected to the positioning member 72, and the second end of the vertical rod 8 passes through the fixing block 73 and is slidably connected to the fixing block 73.

[0041] This utility model connects the first end of the vertical rod 8 to the positioning member 72, and the second end of the vertical rod 8 passes through the fixing block 73 and is slidably connected to the fixing block 73, so that the vertical rod 8 can stabilize the positioning member 72 during sliding, avoid the positioning member 72 from shaking during sliding and moving, and prevent the positioning member 72 from becoming loose, thereby improving the sliding stability of the positioning member 72.

[0042] In one embodiment of the tobacco screening machine of this utility model that facilitates screen replacement, such as... Figure 3 As shown, the mounting component 7 also includes a push block 9, which is disposed on the outside of the positioning member 72.

[0043] By setting the push block 9, this utility model can increase the contact area between the user and the positioning member 72, avoid the small contact area between the positioning member 72 and the user, and improve the pushing efficiency of the positioning member 72.

[0044] In one embodiment of the tobacco screening machine of this utility model that facilitates screen replacement, in order to increase the stability of the positioning component 72 moving on the horizontal plate 5, a sliding groove is provided on the horizontal plate 5, and a slider is provided on the inner side wall of the positioning component 72, and the slider is slidably disposed in the sliding groove.

[0045] In one embodiment of the tobacco screening machine of this utility model that facilitates screen replacement, such as... Figure 3 As shown, a pull ring 10 is provided on the right side of the limiting plate 71.

[0046] By providing a pull ring 10, this utility model makes it easier for users to pull the limiting plate 71 to move, avoiding the difficulty in gripping the limiting plate 71 during the movement process, which would make the limiting plate 71 difficult to pull, thus improving the control efficiency of the limiting plate 71.

[0047] In one embodiment of the tobacco screening machine of this utility model that facilitates screen replacement, such as... Figure 1 , Figure 2 and Figure 4 As shown, two handles 11 are provided on the horizontal plate 5. The two handles 11 are respectively located near the two ends of the horizontal plate 5, and the mounting component 7 is located between the two handles 11.

[0048] By providing a handle 11, this utility model makes it easier for users to pull the horizontal plate 5 to move, avoiding the difficulty in securing the horizontal plate 5 during movement, which would otherwise make it difficult to pull the horizontal plate 5, thus improving the operating efficiency of the horizontal plate 5.

[0049] In one embodiment of the tobacco screening machine of this utility model that facilitates screen replacement, such as... Figure 4 As shown, a reinforcing block 12 is provided between the handle 11 and the cross plate 5.

[0050] By setting a reinforcing block 12, this utility model can reinforce the connection between the handle 11 and the horizontal plate 5, prevent the handle 11 and the horizontal plate 5 from breaking during use, prevent the handle 11 and the horizontal plate 5 from not fitting together, and improve the use effect of the handle 11 and the horizontal plate 5.

[0051] The working principle and usage process of this utility model are as follows: Figures 1 to 4 As shown, when a screen needs to be replaced, the operator applies force to the positioning component 72, causing it to move downwards. This downward movement compresses the limiting spring 74, separating the positioning component 72 from the limiting plate 71. Once the limiting plate 71 is no longer fixed, the operator can rotate it to separate it from the horizontal plate 5, thus pulling the horizontal plate 5 outwards. The horizontal plate 5 then moves the screen body 6 outwards, allowing it to exit the vibrating box 3. No other components need to be disassembled during this process. The entire screen replacement process does not require disassembling any other components; the screen can be directly removed, improving the screen replacement speed.

[0052] When the screen needs to be installed, the operator applies force to the limiting plate 71, causing it to rotate above the installation opening via a hinge. Then, the operator inserts the screen body 6 into the installation opening. Next, the operator applies force to the positioning member 72, causing it to move downwards. This downward movement compresses the limiting spring 74. At this point, the operator rotates the limiting plate 71, moving it to abut against the horizontal plate 5. Then, the operator releases the force on the positioning member 72, allowing it to return to its initial position under the action of the limiting spring 74. This causes the positioning member 72 to engage with the limiting plate 71, providing both limiting and fixing functions.

[0053] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
