Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of toner processing technology, and more specifically, to a rapid sampling device for toner production. Background Technology

[0002] In the early days, some companies used manual scooping to collect toner samples. Operators used a spoon-like tool to directly scoop samples from the toner production equipment's outlet. This method was not only inefficient, requiring a significant amount of time for each sampling, severely impacting production progress, but also made it difficult to guarantee the representativeness of the samples. Due to the randomness of manual operation, the sampling location might be singular, failing to comprehensively reflect the true quality of the entire batch of toner. This could lead to deviations in subsequent quality testing results. For example, if the toner was unevenly distributed within the production equipment, sampling from only a fixed location might yield toner with excessively high or low concentrations in certain areas. Using this as a basis for quality assessment would mislead the judgment of the overall product quality.

[0003] There are also some simple sampling devices that, while improving sampling efficiency to some extent, have significant deficiencies in sealing and screening functions. These devices cannot effectively prevent toner leakage during sampling, which not only wastes toner but also pollutes the working environment and poses potential health hazards to operators. Moreover, they lack a toner screening mechanism and cannot remove impurities and large particles from the toner, resulting in sampling results containing substandard components. This also affects the accurate assessment of toner quality. For example, when toner is mixed with impurities such as metal shavings from wear and tear of production equipment, unscreened samples can lead to misjudgments of toner quality, causing substandard products to enter the market and damaging the company's reputation.

[0004] With the continuous advancement of toner production technology, the requirements for product quality are becoming increasingly stringent. Traditional sampling methods and devices can no longer meet production needs. Enterprises urgently need a new type of sampling device that can quickly and accurately sample while possessing good sealing performance and screening functions to ensure the stability and reliability of toner quality and gain an advantage in fierce market competition. It is against this backdrop that this rapid sampling device for toner production has emerged, aiming to address the shortcomings of existing technologies and provide strong support for quality control in toner production. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a rapid sampling device for toner production, which solves the technical problem that the existing technology has obvious defects in sealing and screening functions. Such devices cannot effectively prevent toner leakage during the sampling process, which not only wastes toner but also pollutes the working environment and poses a potential hazard to the health of operators.

[0006] According to one aspect, at least one embodiment of this disclosure provides a rapid sampling device for toner production, comprising:

[0007] A feeding hood, wherein a sampling tube is provided at the lower end of the feeding hood;

[0008] A sealed sampling assembly is disposed at the lower end of the sampling tube;

[0009] An oscillating screening component is disposed inside the feed hood;

[0010] The sealed sampling assembly includes two connecting rings, which are disposed on the lower end face of the sampling tube. A connecting tube is provided between the two connecting rings. A discharge tube is provided on the lower end face of the sampling tube. A sealing plate is provided inside the connecting ring. A drive shaft is pin-connected to the sealing plate. One end of the drive shaft extends out of the connecting ring, and a drive handle is provided at the end of the drive shaft extending out of the connecting ring.

[0011] As a further technical solution, a connector is fitted onto the sealing plate, and a keyway is provided inside the connector. The drive shaft is inserted into the inside of the connector, and the drive shaft and the keyway are fixedly connected by a key pin.

[0012] As a further technical solution, the vibrating screening component includes a drive platform, which is disposed on the outer side wall of the feed hood. An output motor is disposed on the drive platform, and a drive cam is disposed at the output end of the output motor. A drive frame is disposed on the drive cam, and a linkage frame is disposed at the upper end of the drive frame. One end of the linkage frame is inserted into the interior of the feed hood, and a filter screen is disposed inside the feed hood.

[0013] As a further technical solution, the inner wall of the feed hood is provided with a connecting strip, the connecting strip is pin-connected to the filter screen, and the filter screen is pin-connected to the linkage frame.

[0014] As a further technical solution, the linkage frame is an inverted U-shaped structure, and the linkage frame and the drive frame are connected by a pin.

[0015] As a further technical solution, the feed hood is an inverted conical structure, and the feed hood is connected to the sampling tube.

[0016] As a further technical solution, the filter screen has a circular structure, the filter screen matches the structure of the feed hood, and the filter screen is attached to the inner wall of the feed hood.

[0017] As a further technical solution, a drive disk is provided at the end of the drive shaft, and the drive handle is screwed onto the side wall of the drive disk.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the device significantly shortens the sampling time through the coordinated operation of the sealed sampling component and the vibrating screening component. In the sealed sampling component, the operator only needs to rotate the drive handle to quickly control the opening and closing of the sealing plate, thereby opening and closing the sampling channel. Compared with the manual scooping method, the operation process is simpler and faster. At the same time, the vibrating screening component can quickly screen the toner before it enters the sampling stage, eliminating the need for additional manual screening operations and further saving time. The entire sampling process can be automated and accelerated, effectively improving production efficiency and reducing the impact of sampling operations on production progress, enabling enterprises to conduct toner quality testing more efficiently.

[0020] 2. In this disclosure, the oscillating screening component can accurately remove impurities and large particles from the toner. The output motor drives the drive cam to rotate, which in turn drives the filter screen to vibrate at high frequency, allowing the toner to move fully on the screen. Only toner particles that meet the requirements can pass through the screen and enter the sampling stage. This process ensures the purity and uniformity of the sample, effectively avoiding misjudgments in quality testing caused by impurities and large particles. In addition, the excellent sealing performance of the sealed sampling component prevents toner leakage during the sampling process and avoids contamination of the sample by external factors. This ensures that the quality of the sample does not change during the process from the production equipment to the sampling container, thus providing a real and reliable sample for subsequent quality testing. This helps companies to more accurately control toner quality and improve product quality stability and market competitiveness. Attached Figure Description

[0033] like Figures 1-4 As shown, a rapid sampling device for toner production according to this disclosure is illustrated, comprising:

[0034] Feed hood 1, with a sampling tube 2 installed at the lower end of feed hood 1;

[0035] Sealed sampling assembly 3 is located at the lower end of sampling tube 2;

[0036] Vibrating screening component 4 is installed inside the feed hood 1;

[0037] The sealed sampling assembly 3 includes two connecting rings 3-1. The two connecting rings 3-1 are located on the lower end face of the sampling tube 2. A connecting tube 3-2 is provided between the two connecting rings 3-1. A discharge tube 3-3 is provided on the lower end face of the sampling tube 2. A sealing plate 3-4 is provided inside the connecting ring 3-1. A drive shaft 3-5 is connected to the sealing plate 3-4 by a pin. One end of the drive shaft 3-5 extends out of the connecting ring 3-1. A drive handle 3-6 is provided on the end of the drive shaft 3-5 that extends out of the connecting ring 3-1.

[0038] The vibrating screening component 4 includes a drive platform 4-1, which is located on the outer wall of the feed hood 1. An output motor 4-2 is installed on the drive platform 4-1, and a drive cam 4-3 is installed at the output end of the output motor 4-2. A drive frame 4-4 is installed on the drive cam 4-3, and a linkage frame 4-5 is installed at the upper end of the drive frame 4-4. One end of the linkage frame 4-5 is inserted into the interior of the feed hood 1, and a filter screen 4-6 is installed inside the feed hood 1.

[0039] In some examples, during actual installation, the feed hood 1 needs to be securely installed near the outlet of the toner production equipment to ensure a tight connection between the inlet and outlet of the feed hood 1, preventing toner leakage. Simultaneously, the size and capacity of the feed hood 1 should be rationally designed according to the toner production flow rate and sampling frequency to meet the needs of efficient sampling. Two connecting rings 3-1 are tightly positioned on the lower end face of the sampling tube 2, and a connecting tube 3-2 is installed between the connecting rings 3-1 to ensure a firm and well-sealed connection, preventing toner leakage at the connection point. During installation, auxiliary materials such as sealant can be used to enhance the sealing. The sealing plate 3-4 is installed inside the connecting ring 3-1 and connected to the drive shaft 3-5 via a pin, allowing the sealing plate 3-4 to rotate around the pin. One end extends out through the connecting ring 3-1 for ease of operation. During assembly, ensure the pin is securely installed, the sealing plate 3-4 rotates freely, and the sealing performance between the sealing plate 3-4 and the connecting ring 3-1 is good. The operator rotates the drive handle 3-6 to drive the drive shaft 3-5, thereby controlling the opening and closing of the sealing plate 3-4. When installing the drive handle 3-6, ensure the threaded connection is tight to facilitate the operator's application of force. When sampling is required, the operator rotates the drive handle 3-6, and the drive shaft 3-5 drives the sealing plate 3-4 to rotate around the pin, opening the sampling channel. Toner flows out from the sampling tube 2 through the connecting tube 3-2 and the discharge tube 3-3 for sampling. After sampling, rotate the drive handle 3-6 in the opposite direction to close the sealing plate 3-4 and prevent toner leakage.

[0040] The drive platform 4-1 is installed on the outer wall of the feed hood 1. It should be securely installed and able to withstand the vibrations generated by the output motor 4-2 during operation. The output motor 4-2 is fixed to the drive platform 4-1, and its output end is connected to the drive cam 4-3, ensuring high coaxiality and smooth transmission. During installation, the output motor 4-2 should be adjusted to ensure correct rotation and sufficient output power for the drive requirements. The drive cam 4-3 is installed at the output end of the output motor 4-2, and the drive frame 4-4 engages with the drive cam 4-3. When the output motor 4-2 operates, the drive cam 4-3 rotates, pushing the drive frame 4-4 up and down. During assembly, ensure good contact and smooth movement between the drive cam 4-3 and the drive frame 4-4 to avoid jamming. Start the output motor 4-2, which drives the drive cam 4-3 to rotate. The drive cam 4-3 pushes the drive frame 4-4 to move up and down. The drive frame 4-4 drives the filter screen 4-6 to vibrate up and down inside the feed hood 1 through the linkage frame 4-5. After the toner enters from the feed hood 1, it is screened by the filter screen 4-6. Toner that meets the requirements passes through the screen and enters the sampling component below, while impurities that do not meet the requirements remain on the screen. This achieves the function of oscillating and screening the toner, improving the accuracy of sampling and the quality of the sample.

[0041] like Figures 1-4As shown, in this embodiment, a connector 3-7 is fitted onto the sealing plate 3-4. A keyway 3-8 is provided inside the connector 3-7. The drive shaft 3-5 is inserted into the inside of the connector 3-7. The drive shaft 3-5 and the keyway 3-8 are fixedly connected by a key pin.

[0042] In some examples, a connector 3-7 is fitted onto the sealing plate 3-4. A keyway 3-8 is provided inside the connector 3-7. The drive shaft 3-5 is inserted into the connector 3-7 and fixedly connected to the keyway 3-8 by a key pin. This connection method ensures that the drive shaft 3-5 can effectively drive the sealing plate 3-4 to rotate, while ensuring that the connection between the drive shaft 3-5 and the sealing plate 3-4 is stable and reliable during rotation. When installing the key pin, attention should be paid to the matching degree between its size and the keyway 3-8 to ensure a tight connection.

[0043] For example, such as Figure 2 As shown, the inner wall of the feed hood 1 is provided with a connecting strip 4-7, which is connected to the filter screen 4-6 by a pin, and the filter screen 4-6 is connected to the linkage frame 4-5 by a pin.

[0044] In some examples, a connecting strip 4-7 is provided on the inner wall of the feed hood 1, and the filter screen 4-6 is also connected to the connecting strip 4-7 by a pin. This connection method allows the filter screen 4-6 to vibrate up and down to screen toner under the drive of the linkage frame 4-5. During installation, it is necessary to ensure that each pin is firmly connected, the linkage frame 4-5 moves flexibly, and the filter screen 4-6 is installed flat and fits well with the inner wall of the feed hood 1 to ensure the screening effect.

[0045] For example, such as Figure 1 As shown, the linkage frame 4-5 has an inverted U-shaped structure, and the linkage frame 4-5 is connected to the drive frame 4-4 by a pin.

[0046] In some examples, the linkage frame 4-5 is an inverted U-shaped structure, with one end connected to the drive frame 4-4 via a pin to ensure flexible connection and accurate motion transmission. The other end of the linkage frame 4-5 is inserted into the feed hood 1 and connected to the filter screen 4-6 via a pin.

[0047] For example, such as Figure 2 As shown, the feed hood 1 is an inverted conical structure, and the feed hood 1 is connected to the sampling tube 2.

[0048] In some examples, the feed hood 1 adopts an inverted conical structure. This design helps to guide the toner to flow in a concentrated manner to the sampling tube 2 below, allowing the toner to enter the sampling area more smoothly under the action of gravity. The feed hood 1 and the sampling tube 2 are connected to ensure that the toner can smoothly enter the subsequent sampling components from the feed hood 1.

[0049] For example, such as Figure 2As shown, the filter screen 4-6 has a circular structure, and the filter screen 4-6 matches the structure of the feed hood 1. The filter screen 4-6 is attached to the inner wall of the feed hood 1.

[0050] In some examples, the filter screen 4-6 adopts a circular structure, the size of which matches the internal dimensions of the feed hood 1. This ensures that the filter screen 4-6 can fit tightly against the inner wall of the feed hood 1, preventing toner from passing through the gap between the screen and the feed hood 1 and affecting the screening effect. The mesh size of the filter screen 4-6 should be reasonably selected according to the particle size requirements of the toner to ensure that standard toner particles can be effectively screened out. When installing the filter screen 4-6, care should be taken to install it flat inside the feed hood 1. It is connected to the linkage frame 4-5 and the connecting bar 4-7 by pins to ensure its stability during vibration. The wear condition of the filter screen 4-6 should be checked regularly, and it should be replaced in time if there is any damage to ensure the normal operation of the screening function.

[0051] For example, such as Figure 1 As shown, a drive disc 5 is provided at the end of the drive shaft 3-5, and the drive handle 3-6 is screwed onto the side wall of the drive disc 5.

[0052] During use, after the toner is discharged from the outlet of the toner production equipment, it enters the inverted conical feed hood 1. Utilizing the special conical structure of the feed hood 1, the toner naturally converges under the action of gravity and flows downward to the sampling tube 2, completing the initial guidance and concentration, laying the foundation for subsequent screening and sampling. At the same time, the feed hood 1 is connected to the sampling tube 2 to ensure that the toner can smoothly enter the device without clogging or leakage.

[0053] When the toner enters the feed hood 1, the output motor 4-2 is started. The output motor 4-2 drives the drive cam 4-3 to start rotating. During the rotation of the drive cam 4-3, its special contour shape pushes the drive frame 4-4 to move up and down reciprocally. The drive frame 4-4 is connected to the linkage frame 4-5 through the pin shaft, which transmits the motion to the filter screen 4-6 inside the feed hood 1. Since the filter screen 4-6 is connected to the linkage frame 4-5 and the connecting strip 4-7 on the inner side wall of the feed hood 1 through the pin shaft, the filter screen 4-6 vibrates up and down inside the feed hood 1 under the drive of the linkage frame 4-5.

[0054] During the vibration of the filter screen 4-6, the toner continuously moves on the screen. Toner particles that meet the requirements pass through the mesh of the screen and fall below; while impurities and large toner particles that do not meet the requirements are intercepted on the screen, thereby achieving the screening of toner and ensuring that the toner entering the sampling stage is of uniform quality and meets the standards.

[0055] When the screened toner reaches the sampling tube 2, the sampling operation is achieved through the sealed sampling assembly 3. The operator rotates the drive handle 3-6, and the drive handle 3-6 drives the drive shaft 3-5 to rotate through the threaded drive disc 5. The drive shaft 3-5 is fixed to the insertion tube 3-7 on the sealing plate 3-4 by a key pin. Therefore, when the drive shaft 3-5 rotates, it will drive the sealing plate 3-4 to rotate around the pin shaft.

[0056] When the sealing plate 3-4 is rotated open, the sampling channel is unobstructed. Toner flows out from the sampling tube 2 through the connecting tube 3-2 and the discharge tube 3-3 and enters the sampling container to complete the sampling. After the sampling is completed, the operator rotates the drive handle 3-6 in the opposite direction to close the sealing plate 3-4, sealing the sampling channel to prevent toner from continuing to flow out and leak, and to ensure the sealing of the device in the non-sampling state.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
