[0025] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0026] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0028] An embodiment of this utility model provides a detachable filter assembly device, such as... Figure 1-7 As shown, it includes:

[0029] The filter structure 100 includes a mounting box 110, which has an inlet 101, an outlet, and a first feeding channel communicating with the inlet 101 and the outlet. The filter structure 100 also includes a filter 120 that can slide along the mounting box 110, and the filter 120 includes a detachable filter screen 130. The filter structure 100 has a working state and a replacement state. When the filter 120 slides into the mounting box 110, the filter screen 130 is connected to the first feeding channel, and the filter structure 100 is in the working state. When the filter 120 slides to the outside of the mounting box 110, the filter structure 100 is in the replacement state.

[0030] The discharge device 200 is connected to the discharge port.

[0031] The mounting box 110 has an inlet 101, an outlet 101, and a first feeding channel, which are interconnected. The filter structure 100 includes the mounting box 110 and a filter 120. The filter 120 can slide within the mounting box 110 and includes a removable filter screen 130. In some embodiments, the filter 120 is provided with a sealing ring. When the filter 120 is inserted into the mounting box 110, the sealing ring can seal the gap between the filter 120 and the mounting box 110, thereby preventing adhesive from leaking from the gap between the filter 120 and the mounting box 110. The interior of the mounting box 110 has a cavity for accommodating the filter 120 and the filter screen 130. One side of the filter 120 has an opening. When the filter 120 slides into the mounting box 110, the opening aligns with the first feeding channel, so that the filter screen 130 is connected to the first feeding channel. In some embodiments, the outer side of the filter 120 has a handle to facilitate the operator to push the filter 120 to slide. The filter screen 130 is installed by a detachable connection. This detachable connection method can be a magnetic connection, where the filter screen 130 has magnetic material and the filter 120 has a corresponding magnetic base. When the filter screen 130 is close to the magnetic base, it can be attracted and fixed. Alternatively, it can be a snap-fit ​​connection, where the filter screen 130 has snap-fit ​​edges and the filter 120 has slots that mate with the snap-fits. Simply snap the snap-fits of the filter screen 130 into the slots to fix it in place. Because the filter screen 130 is easy to replace, downtime caused by filter screen replacement is reduced, thereby improving the overall production efficiency of the dispensing unit.

[0032] The discharge device 200 is connected to the discharge port of the filter structure 100 and is used to discharge the filtered material. The discharge device 200 can be one or more dispensing pipes, each equipped with a control valve. By controlling the opening and closing of the valves, the dispensing flow rate and dispensing time of the material can be controlled, achieving precise dispensing. For example, in adhesive dispensing, the discharge device 200 can dispense the adhesive into different packaging containers, such as plastic buckets and glass bottles, as needed.

[0033] The filter structure 100 has two operating states:

[0034] Operating status: When the filter 120 slides into the mounting box 110 and closes the first feeding channel, the filter screen 130 connects with the first feeding channel. At this time, the material enters from the inlet 101, is filtered by the filter screen 130, and flows out from the outlet. The filter structure 100 is in normal operating condition and plays the role of filtering materials.

[0035] Replacement status: When it is necessary to replace the filter 130, slide the filter 120 until the filter 130 is located outside the mounting box 110. At this time, the filter structure 100 is in the replacement status, which facilitates the disassembly and replacement of the filter 130.

[0036] For example, during the adhesive dispensing process, filter 130 may become clogged with solid impurities in the adhesive, requiring replacement. First, the operator closes the valves at the inlet 101 and outlet to stop material transport. Then, the operator manually slides filter 120 to the replacement position, exposing filter 130 to the outside of the mounting box 110. Next, the operator removes the old filter 130 and installs the new one. After installation, filter 120 is slid back to the operating position, the valve is opened, and the adhesive dispensing operation continues. The entire process is simple to operate, greatly improving the maintenance and production efficiency of the dispensing unit.

[0037] In some embodiments, a removable filter 130 disassembly device further includes a drive device 300 for driving the filter 120 to slide along the mounting box 110.

[0038] The main function of the drive unit 300 is to drive the filter 120 to slide along the mounting box 110, thereby switching the filter structure 100 between the use state and the replacement state. Specifically:

[0039] In use: the drive unit 300 can accurately push the filter 120 into the mounting box 110 and ensure the seal between the filter 120 and the mounting box 110, so that the filter screen 130 can effectively connect the inlet 101 and the outlet, ensuring the normal filtration of materials.

[0040] When changing states: the drive unit 300 can pull out the filter 120, so that the filter screen 130 is located outside the mounting box 110, making it convenient for operators to disassemble and replace the filter screen 130.

[0041] The drive unit 300 can be electrically driven, pneumatically driven, or manually driven. For example, a pneumatic drive uses a cylinder as the actuator, using air pressure to push the filter 120 to slide. The advantages of a pneumatic drive are its simple structure, fast response speed, and low maintenance cost, making it suitable for applications where high precision is not required. An automated or semi-automated drive unit 300 reduces the tedium of manual operation, especially in situations where the filter 130 needs frequent replacement, significantly improving work efficiency.

[0042] Furthermore, the drive unit 300 is a cylinder, and the power output end of the cylinder is connected to the filter 120.

[0043] The cylinder operates simply and directly; operators can control the sliding of the filter 120 with a simple button or switch, without the need for complex mechanical operations.

[0044] When the drive device 300 uses a cylinder, the cylinder push rod extends into the mounting box 110 and is connected to the filter 120. The extension and retraction of the cylinder push rod drives the filter 120 to slide relative to the mounting box 110. A sealing ring can be fitted on the cylinder push rod. When the filter 120 is inserted into the mounting box 110, the sealing ring can abut against the inner wall of the first feeding channel in the mounting box 110 to seal the gap between the mounting box 110 and the push rod.

[0045] In some embodiments, the filter 120 is provided with a second feeding channel 140, and the second feeding channel 140 is provided with a mounting portion 150 for placing the filter screen 130.

[0046] The second feeding channel 140 is a channel for material to flow inside the filter 120. It is connected to the first feeding channel to ensure that the material can pass smoothly through the filter 120. The second feeding channel 140 is provided with a mounting portion 150 for placing the filter screen 130. This mounting portion 150 is the fixed position for the filter screen 130, ensuring that the filter screen 130 is stably installed inside the filter 120 during the filtration process. The mounting portion 150 can be designed as a groove, slot, or threaded structure for fixing the filter screen 130. For example, the filter screen 130 can be fixed to the mounting portion 150 by clips, screws, or clamping devices to ensure that the filter screen 130 does not loosen during the filtration process. In some embodiments, the mounting portion 150 is an annular structure. By providing the mounting portion 150 in the second feeding channel 140, the installation of the filter screen 130 is more stable, reducing the risk of the filter screen 130 loosening or shifting during the filtration process and improving the stability of the filtration effect. The installation and replacement of filter screen 130 is simple and quick, allowing operators to easily replace it, reducing downtime and improving production efficiency. In some embodiments, when the mounting part 150 is a groove, the material to be filtered exerts pressure on filter screen 130 as it passes through filter 120, thereby firmly fixing filter screen 130 within filter 120.

[0047] Furthermore, the mounting section 150 is stepped, and the mounting section 150 divides the second feeding channel 140 into a third feeding channel 141 and a fourth feeding channel 142. The width of the third feeding channel 141 is greater than the width of the fourth feeding channel 142.

[0048] The stepped mounting section 150 provides a stable support surface for the filter screen 130, ensuring that the filter screen 130 does not loosen or shift during filtration. The mounting section 150 divides the second feeding channel 140 into a third feeding channel 141 and a fourth feeding channel 142. This division optimizes the material flow path and improves filtration efficiency. The third feeding channel 141 is wider and primarily accommodates the filter screen 130, ensuring sufficient space for installation and fixation. The fourth feeding channel 142 is narrower and primarily facilitates the flow of filtered material. The narrower width increases the material flow rate within the channel, improving filtration efficiency, while simultaneously reducing the material's residence time within the channel and minimizing impurity accumulation.

[0049] In some embodiments, the filter 120 is cylindrical.

[0050] The cylindrical structure allows the filter 120 to distribute stress more evenly under pressure, reducing localized stress concentration and improving its strength and durability. The cylindrical shape of the filter 120 also allows for a smooth sliding fit with the inner wall of the mounting box 110. The inner wall of the mounting box 110 can be designed to be cylindrical, matching the outer diameter of the filter 120, ensuring smooth sliding of the filter 120.

[0051] In some embodiments, a removable filter 130 dispensing device further includes a heating device for heating the material to be dispensed located within the filter structure 100 and the discharge device 200.

[0052] For some high-viscosity materials, such as adhesives, heating can reduce their viscosity and improve their flowability, allowing them to pass more smoothly through the filter structure 100 and the discharge device 200. In some cases, materials need to be packaged at specific temperatures to ensure their quality and stability. Heating devices can ensure that the materials are kept within a suitable temperature range during the packaging process. For some easily solidified materials, heating can prevent them from solidifying during packaging, ensuring the smooth progress of the packaging process.

[0053] In some embodiments, the heating device may employ electric heating or steam heating. For example, heating elements such as heating wires, heating tubes, or heating films may be used and installed at appropriate locations in the filter structure 100 and the discharge device 200. Alternatively, steam pipes may be provided on the outer walls of the filter structure 100 and the discharge device 200 to heat the material using the heat of steam.

[0054] Furthermore, the discharge device 200 includes a discharge head and a discharge head housing disposed outside the discharge head, forming a first heating channel between the discharge head and the discharge head housing. The filter structure 100 also includes a first feeding pipe 160, a second feeding pipe 170, and a mounting box housing disposed outside the mounting box 110, forming a second heating channel between the mounting box 110 and the mounting box housing. The first feeding pipe 160 is used to connect the inlet 101 and the first feeding channel, and the second feeding pipe 170 is used to connect the discharge outlet and the first feeding channel. A third heating channel is provided between the inner and outer walls of the first feeding pipe 160, and a fourth heating channel is provided between the inner and outer walls of the second feeding pipe 170. The first heating channel, the second heating channel, the third heating channel, and the fourth heating channel are all connected. The heating device includes a heater for heating the heat source and a circulating pump. The circulating pump is used to drive the heat source to flow between the first heating channel, the second heating channel, the third heating channel, the fourth heating channel, and the heater.

[0055] The discharge head is used to discharge the filtered material. The discharge head housing is located outside the discharge head, forming a first heating channel between the discharge head and the discharge head. The first heating channel heats the material inside the discharge head, ensuring the material maintains a suitable temperature during discharge. The first feeding pipe 160 connects the inlet 101 and the first feeding channel, used to introduce material into the filter structure 100. The second feeding pipe 170 connects the outlet and the first feeding channel, used to discharge the filtered material from the filter structure 100. The mounting box housing is located outside the mounting box 110, forming a second heating channel between the mounting box 110 and the mounting box 110. The second heating channel heats the material inside the mounting box 110, ensuring the material maintains a suitable temperature during filtration. The third heating channel is located between the inner and outer walls of the first feeding pipe 160, used to heat the material entering the filter structure 100. The fourth heating channel is located between the inner and outer walls of the second feeding pipe 170, used to heat the filtered material. The first, second, third, and fourth heating channels are all interconnected, forming a complete heating system together with the heater. The heating device includes a circulation pump, which drives the heating source to flow between these heating channels. The heating source is such as hot water, steam or hot oil. The heating source flows between the heating channels to ensure that the material in the entire device is heated evenly. After the heating source completes one flow, it flows back into the heater to be reheated, and then flows back into the first heating channel, the second heating channel, the third heating channel and the fourth heating channel.

[0056] The working principle of this embodiment is as follows:

[0057] A heating source (such as hot water, steam, or hot oil) circulates between various heating channels through a piping system. The temperature of the material can be precisely controlled by adjusting the temperature of the heating source using heaters. By incorporating heating channels at multiple locations in the discharge device 200 and the filter structure 100, the material is ensured to remain within a suitable temperature range throughout the dispensing process, improving dispensing efficiency and material quality. The circulation of the heating source between the various heating channels ensures uniform heating of the material, preventing localized overheating or underheating.

[0058] Furthermore, the heating source is heated oil.

[0059] Heating oil has high thermal stability and can maintain stable physical and chemical properties over a wide temperature range, making it suitable for applications requiring high-temperature heating.
