Description

Technical Field

[0001] The utility model relates to the technical field of ultrafine fiber powder production, and particularly relates to a self-shaking screening machine for ultrafine fiber powder. Background Art

[0002] Ultrafine fiber powder, as the name implies, is a powdery substance with extremely fine fiber diameter, usually derived from various fiber materials through fine processing. After retrieval, the patent with the patent publication number CN207951961U discloses a self-shaking screening machine for wood fiber powder. Although the device can perform double-layer screening on wood fiber powder by setting a sieve frame in the inner cavity of the screening box and a driving motor on the upper side of the left end of the base during use, when the device is in use, the powdery raw materials will cause dust during shaking and feeding, resulting in a poor production environment. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a self-shaking screening machine for ultrafine fiber powder, which solves the problems raised in the background art.

[0004] The solution of the utility model to the above technical problems is as follows:

[0005] A self-shaking screening machine for ultrafine fiber powder, comprising a bracket, and a machine body is installed on the bracket;

[0006] Buffer modules are arranged on both sides of the machine body. The machine body is mounted on the bracket through the buffer modules. The machine body is provided with a sieve frame, a sieve plate is installed in the sieve frame, a guide plate is arranged on the sieve frame, and the guide plates are distributed alternately on the sieve frame. Fixed plates are arranged on both sides of the sieve frame, and vibration motors are installed on the fixed plates. A feeding port is opened at one end of the sieve frame, and a guide block is arranged at one end of the sieve plate close to the feeding port;

[0007] A first feeding module is installed on the bracket at the end of the machine body where the feeding port is opened, and a second feeding module is installed at the bottom end of the machine body.

[0008] Based on the above technical solutions, the utility model can be further improved as follows.

[0009] Further, the guide blocks are symmetrically distributed on the sieve frame, and the guide blocks guide the materials screened and retained on the sieve frame to the feeding port for feeding.

[0010] The beneficial effects of adopting the above further scheme are:

[0011] The symmetrically distributed guiding blocks can ensure the uniform distribution of materials within the sieve frame, enabling the materials to flow evenly towards the discharge opening throughout the entire sieve frame. This uniform guiding helps reduce the accumulation and uneven distribution of materials within the sieve frame, avoiding blockage phenomena during the screening process. The guiding blocks effectively guide the materials within the sieve frame to the discharge opening, ensuring that the materials can smoothly pass through the discharge opening and be discharged. This guiding mechanism reduces the stagnation and backlog of materials, improves the overall discharging efficiency, and reduces the need for operator intervention during the discharging process.

[0012] Furthermore, the first discharging module is provided with a guiding hopper, which is inserted and installed on a fixing block, and the fixing block is fixed on the crossbeam of the support.

[0013] The beneficial effect of adopting the above further solution is:

[0014] The fixing block is fixed on the crossbeam of the support, which can provide stable support and keep the guiding hopper in a fixed position during operation. This design can prevent the guiding hopper from shifting or shaking during the operation of the equipment, thus ensuring the stability of the discharging process.

[0015] Furthermore, the second discharging module is provided with a discharging hopper, and the bottom end of the discharging hopper is provided with a discharge opening, and negative ion generators are installed on both sides of the discharge opening.

[0016] The beneficial effect of adopting the above further solution is:

[0017] The negative ion generators can release negative ions, which combine with dust particles in the air, increasing their weight and accelerating sedimentation, thereby effectively reducing the suspension of dust. By installing negative ion generators on both sides of the discharge opening, the dust diffusion during the discharging process can be significantly reduced, improving the air quality of the working environment.

[0018] Furthermore, the negative ion generators are connected with probes through connecting wires, and the probes are inserted into the discharging hopper.

[0019] The beneficial effect of adopting the above further solution is:

[0020] By effectively reducing dust, the negative ion generators can improve the air quality of the working environment, reducing the respiratory irritation and health risks of operators. This helps improve the work comfort and safety of employees. By reducing the dust concentration, the dust accumulation inside and around the equipment is reduced, which can lower the cleaning and maintenance frequency of the equipment and reduce the workload of manual maintenance.

[0021] Furthermore, the buffer module is provided with a connecting seat, which is installed on the machine body, and a spring is connected between the connecting seat and the support.

[0022] The beneficial effect of adopting the above further solution is:

[0023] The spring plays a buffering role between the connecting seat and the bracket, effectively absorbing and reducing the vibration of the machine body during the vibration process. This reduces the impact of vibration on the equipment structure and its internal components, thereby protecting the long-term stability of the equipment. The buffering effect of the spring helps to keep the machine body stable on the bracket, reducing the displacement and shaking caused by vibration. This can ensure the stability and reliability of the equipment during operation, avoiding structural loosening or damage caused by vibration.

[0024] Furthermore, a connecting column is provided at the bottom end of the connecting seat, and the spring is limit-mounted at the bottom end of the connecting seat through the connecting column.

[0025] The beneficial effects of adopting the above further solution are as follows:

[0026] The design of the connecting column ensures the fixed position of the spring at the bottom end of the connecting seat. The design of the connecting column can provide accurate spring positioning, ensuring that the spring works at a predetermined position. It improves the assembly accuracy and helps the equipment to maintain good performance and consistency during operation. This stable installation method can prevent the spring from shifting or falling off during the working process, thus maintaining the stability and reliability of the entire system.

[0027] The utility model provides a self-shaking type screening machine for ultrafine fiber powder. It has the following

[0028] beneficial effects:

[0029] A sieve plate is installed in the sieve frame of the screening machine, and the powdery material is effectively screened through the sieve plate. The guide plates provided on the sieve frame are arranged in a staggered manner, increasing the residence time of the material on the sieve plate. This design can ensure that the material fully contacts and is screened on the sieve plate, improving the screening accuracy and reducing the waste of the material. At one end of the sieve frame, close to the feeding port, guide blocks are installed. These guide blocks are symmetrically distributed on the sieve frame and can effectively guide the unscreened material to the position of the feeding port. This design not only ensures the timely feeding of the material but also further improves the screening effect, making the screened material more uniform. The guide blocks not only help the material move smoothly to the feeding port but also prevent the material from stagnating in the sieve frame. This design ensures that the screened material can be discharged in a timely manner, avoiding the problem of material accumulation during the screening process. The reasonable design of the feeding port and the feeding hopper enables the material to be discharged smoothly from the sieve frame, reducing the obstruction and jamming phenomena during the feeding process.

[0030] The machine body is mounted on the bracket through a buffer module. A connecting seat is arranged in the buffer module, and the connecting seat is connected to the bracket by a spring. This spring connection method enables the machine body to achieve self-shaking when the vibration motor is working. This self-shaking function helps to prevent the blockage of materials during the screening process and avoid the accumulation of materials on the sieve plate, thus ensuring the stability of the screening efficiency. Vibration motors are installed on both sides of the sieve frame, and the vibration of the motors makes the sieve frame and the sieve plate generate high-frequency vibrations, enhancing the dispersion of materials and the screening efficiency. The combination of the self-shaking design and the vibration motor further improves the overall performance of the screening machine.

[0031] In the second blanking module, a negative ion generator is installed. The negative ion generator can release a large number of negative ions, which can combine with dust particles in the air, make the dust particles heavier and accelerate sedimentation, thus effectively reducing the diffusion of dust during the blanking process. This not only improves the working environment during the blanking process, but also reduces the wear and pollution of the equipment by dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Please refer to Figures 1 to 4 as shown in the figure, the embodiments provided by the present utility model are as follows:

[0042] Embodiment 1

[0043] A self-swaying screening machine for ultrafine fiber powder includes a support 2, on which a body 1 is mounted. Buffer modules 4 are provided on both sides of the body 1, which is supported on the support 2 via the buffer modules 4. The buffer modules 4 include a connecting seat 402, which is mounted on the body 1. A spring 403 is connected between the connecting seat 402 and the support 2. The spring 403 acts as a buffer between the connecting seat 402 and the support 2, effectively absorbing and reducing vibrations of the body 1 during vibration. This reduces the impact of vibration on the device structure and its internal components, thereby protecting the long-term stability of the device. The buffering effect of the spring 403 helps maintain the stability of the body 1 on the support 2, reducing displacement and shaking caused by vibration. This ensures the stability and reliability of the device during operation and prevents structural loosening or damage caused by vibration. A connecting post 401 is provided at the bottom end of the connecting post 401, and the spring 403 is fixed to the bottom end of the connecting post 401. The design of the connecting post 401 ensures that the spring 403 is fixed in place at the bottom end of the connecting post 402. The design of the connecting column 401 can provide accurate positioning of the spring 403, ensuring that the spring 403 works at the predetermined position. The assembly accuracy is improved, which helps the equipment maintain good performance and consistency during operation. This stable installation method can prevent the spring 403 from being displaced or falling off during operation, thereby maintaining the stability and reliability of the entire system. The body 1 is provided with a screen frame 107, and a screen plate 101 is installed in the screen frame 107. The powdered material is screened by the screen plate 101. The screen frame 107 is provided with a guide plate 102, and the guide plates 102 are staggered on the screen frame 107. The guide plates 102 increase the residence time of the material on the screen plate 101 so that the material is fully screened. Fixed plates are provided on both sides of the screen frame 107. Plate 103, a vibration motor 104 is installed on the fixed plate 103, a discharge port 106 is opened at one end of the screen frame 107, and a guide block 105 is provided at the end of the screen plate 101 near the discharge port 106. The guide blocks 105 are symmetrically distributed on the screen frame 107. The guide blocks 105 guide the material retained on the screen frame 107 to the discharge port 106 for discharge. The symmetrically distributed guide blocks 105 can ensure the uniform distribution of the material in the screen frame 107, so that the material flows evenly to the discharge port 106 in the entire screen frame 107. This uniform guidance helps to reduce the accumulation and uneven distribution of materials in the screen frame 107, avoiding blockage during the screening process. The guide blocks 105 effectively guide the material in the screen frame 107 to the discharge port 106, ensuring that the material can be discharged smoothly through the discharge port 106. This guiding mechanism reduces the stagnation and backlog of materials, improves the overall discharge efficiency, and reduces the need for operator intervention during the discharge process.

[0044] Example 2

[0045] In order to facilitate the collection of screened materials and prevent the materials from raising dust, for example, Figures 1 to 4As shown in the figure, the present invention further includes: a first blanking module 3 is installed at one end of the bracket 2 where the blanking port 106 is opened on the body 1. The first blanking module 3 is provided with a guiding hopper 301, and the guiding hopper 301 is inserted and installed on the fixing block 302. The fixing block 302 is fixed on the cross beam of the bracket 2. The fixing block 302 fixed on the cross beam of the bracket 2 can provide stable support, so that the guiding hopper 301 maintains a fixed position during operation. This design can prevent the guiding hopper 301 from shifting or shaking during the operation of the equipment, thereby ensuring the stability of the blanking process. A second blanking module 5 is installed at the bottom end of the body 1. The second blanking module 5 is provided with a blanking hopper 504. The bottom end of the blanking hopper 504 is provided with a discharge port 502. Negative ion generators 501 are installed on both sides of the discharge port 502. The negative ion generators 501 can release negative ions. These negative ions combine with dust particles in the air, making them increase in weight and accelerate sedimentation, thereby effectively reducing the suspension of dust. By installing the negative ion generators 501 on both sides of the discharge port 502, the dust diffusion during the blanking process can be significantly reduced, and the air quality of the working environment can be improved. The negative ion generators 501 are connected with probes through connecting wires 503, and the probes are inserted into the blanking hopper 504. By effectively reducing dust, the negative ion generators 501 can improve the air quality of the working environment, reduce the respiratory irritation and health risks of operators. This helps to improve the work comfort and safety of employees. By reducing the dust concentration, the dust accumulation in the equipment and the surrounding environment is reduced. This can reduce the cleaning and maintenance frequency of the equipment and reduce the workload of manual maintenance.

[0046] Working principle:

[0047] First, the material is put into the inside of the sieve frame 107. A sieve plate 101 is installed in the sieve frame 107. The sieve plate 101 conducts preliminary particle size separation on the material through its aperture. Smaller particles will fall through the aperture of the sieve plate 101, while larger particles will be retained on the sieve plate 101.

[0048] Next, vibration motors 104 are installed on both sides of the sieve frame 107. The vibration motors 104 generate high-frequency vibrations during operation. This vibration is transmitted to the sieve frame 107, causing the material to continuously move on the sieve plate 101, thereby improving the screening efficiency of the material. At the same time, the body 1 is erected on the bracket 2 through the buffer module 4. The buffer module 4 includes a spring 403 and a connecting seat 402. When the vibration motor 104 works, the spring 403 will deform due to the vibration, causing the body 1 to produce a self-shaking effect. This self-shaking can prevent the material from accumulating on the sieve plate 101 and make the material more evenly distributed on the sieve plate 101.

[0049] Inside the sieve frame 107, guide plates 102 are arranged in a staggered distribution. The function of the guide plates 102 is to extend the residence time of the material on the sieve plate 101, so that it can be fully screened on the sieve plate 101. As the screening process progresses, some larger particle materials that do not pass through the screening will be guided by the guide blocks 105 to the discharge port 106. The reasonable design of the guide blocks 105 ensures that the material can be discharged smoothly and avoids the occurrence of blockage.

[0050] On the bracket 2 of the screening machine, a first discharging module 3 is installed near the discharge port 106. The guide hopper 301 in this module is used to receive the material discharged from the discharge port 106 to ensure that the material can fall smoothly. At the bottom end of the machine body 1, a second discharging module 5 is also installed. Here, a discharging hopper 504 is provided to receive the fine particle materials after screening. The bottom of the discharging hopper 504 is provided with a discharge port 502, and the fine particle materials are finally discharged through the discharge port 502.

[0051] To solve the dust problem, negative ion generators 501 are installed on both sides of the discharging hopper 504. When the material enters the discharging hopper 504, the negative ion generators 501 will release negative ions. These negative ions combine with the dust particles in the air, causing the dust to settle faster, thus effectively reducing the environmental pollution caused by the dust and ensuring that the equipment can maintain a good working environment under different working conditions.
