Description

Technical Field

[0001] This utility model relates to the field of pulp molding technology, and in particular to a pulp mold cleaning device. Background Technology

[0002] In the pulp molding industry, mold surface cleaning is a crucial step in product manufacturing. Pulp molding uses raw materials such as pulp fibers to form various packaging products within a mold. After the product is formed, pulp fibers, impurities, and other stains remain on the mold surface. If these are not cleaned promptly and effectively, they will affect product quality and accelerate mold wear.

[0003] Currently, there are two main methods for cleaning mold surfaces in pulp molding production. The first is manual rinsing, where operators use water guns and other tools to wash the mold surface. However, this method is labor-intensive, requires equipment to be stopped, interrupts the production process, and reduces efficiency. Furthermore, the cleanliness depends heavily on the worker's skill level, with varying cleaning results between different workers, and the overall time commitment is also long. The second method is a fixed, mold-following cleaning device, which is fixedly linked to the mold and cleans as it moves. However, this method can only clean the mold under specific conditions, namely when the upper mold is moving. It cannot clean independently when the mold is stationary or under other complex conditions, lacking flexibility and failing to meet diverse production needs.

[0004] Existing cleaning technologies suffer from high costs, low efficiency, inconsistent cleaning results, and insufficient flexibility, making them unsuitable for the high-efficiency, high-quality production requirements of the modern pulp molding industry. Therefore, there is an urgent need for a new cleaning technology and device that can clean molds at any time without affecting other processes, allowing for multiple cleanings and ensuring a more uniform and thorough cleaning of the mold surface, thereby improving production efficiency and product quality. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a pulping mold cleaning device, including: a bracket, a spraying assembly, a connecting hose, and an inlet pipe;

[0007] The inlet pipe is fixedly connected to the bracket, and the spray assembly can be slidably connected to the bracket;

[0008] The inlet of the inlet pipe is used to connect high-pressure water or high-pressure air, the outlet of the inlet pipe is connected to the inlet of the connecting hose, the outlet of the connecting hose is connected to the inlet of the spray assembly, and the outlet of the spray assembly is used to clean the pulping mold.

[0009] Preferably, the pulping mold cleaning device further includes a three-pipe connection, wherein the first inlet of the three-pipe connection is connected to high-pressure water, the second inlet of the three-pipe connection is connected to high-pressure air, and the outlet of the three-pipe connection is connected to the inlet of the inlet pipe.

[0010] Preferably, the pulping mold cleaning device further includes a control component, a regulating water valve, and a regulating air valve. The regulating water valve is installed at the first inlet of the three-way connecting pipe, and the regulating air valve is installed at the second inlet of the three-way connecting pipe. The regulating water valve and the regulating air valve are electrically connected to the control component.

[0011] The water regulating valve is used to control the opening and closing of the water and to adjust the amount of flushing air. The air regulating valve is used to control the opening and closing of the air and to adjust the amount of flushing air.

[0012] Preferably, the bracket includes a fixing plate and a fixing member. The fixing member is fixedly connected to one end of the fixing plate. The fixing member includes a mounting plate, a connecting plate, and a support plate. The mounting plate, the connecting plate, and the support plate are perpendicular to each other and fixedly connected to each other.

[0013] Preferably, the pulping mold cleaning device further includes a guide rail and a fixed spray arm, the guide rail is fixedly connected to the fixed plate, and the spray assembly includes a sliding spray arm;

[0014] The sliding spray arm and the fixed spray arm are spaced apart along the extension direction of the guide rail. The sliding spray arm is slidably connected to the guide rail, and the fixed spray arm is fixedly connected to the fixed plate. The inlet of the fixed spray arm is used to connect high-pressure water or high-pressure air, and the outlet of the fixed spray arm is used to clean the pulping mold.

[0015] Preferably, the pulping mold cleaning device further includes a sliding plate, a sliding spray arm is fixedly connected to the sliding plate, and the sliding plate is fixedly connected to the guide rail.

[0016] Preferably, the pulping mold cleaning device further includes a cylinder, which is fixedly connected to a fixed plate, and the output shaft of the cylinder is connected to a sliding spray arm.

[0018] Preferably, the pulping mold cleaning device further includes a first rotary joint and a second rotary joint, the first rotary joint being installed between the outlet of the inlet pipe and the inlet of the connecting hose, and the second rotary joint being installed between the outlet of the connecting hose and the inlet of the spray assembly.

[0019] Compared with the prior art, the beneficial effects of the pulping mold cleaning device of this utility model embodiment are as follows:

[0020] (1) The spray assembly can be slidably connected to the bracket. The connecting hose, combined with the guide rail and sliding spray arm design, allows the spray assembly to move flexibly on the bracket, enabling comprehensive and multi-angle cleaning of the pulping mold, avoiding cleaning dead corners, and improving cleaning effect and efficiency.

[0021] (2) The sliding connection design of the spray assembly enables the cleaning process to be automated or semi-automated to a certain extent. Compared with traditional manual cleaning methods, this reduces the workload and labor intensity of manual operation.

This design allows the cleaning device to flexibly select the cleaning medium according to the specific conditions of the pulping mold. For some stubborn stains, high-pressure water can wash them away with its strong impact force; while for some sticky substances or situations requiring rapid drying, high-pressure air can remove moisture and impurities by blowing them dry. By flexibly switching the cleaning medium, it can better adapt to the cleaning needs of different molds and improve the cleaning effect. Attached Figure Description

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "vertical", "horizontal", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", and "outer" used to indicate the orientation or positional relationship 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.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figs. 1-2 As shown, a preferred embodiment of the present invention for cleaning a pulping mold includes: a support 1, a spray assembly 2, a connecting hose 3, and an inlet pipe 4;

[0032] The inlet pipe 4 is fixedly connected to the bracket 1, and the spray assembly 2 is slidably connected to the bracket 1;

[0033] The inlet of the inlet pipe 4 is used to connect high-pressure water or high-pressure air. The outlet of the inlet pipe 4 is connected to the inlet of the connecting hose 3. The outlet of the connecting hose 3 is connected to the inlet of the spray assembly 2. The outlet of the spray assembly 2 is used to clean the pulping mold.

[0034] Based on the above scheme, the spray assembly 2 can be slidably connected to the bracket 1. The connecting hose 3, in conjunction with the guide rail 7 and the sliding spray arm 21, allows the spray assembly 2 to move flexibly on the bracket 1, enabling comprehensive and multi-angle cleaning of the pulping mold, avoiding cleaning dead spots, and improving cleaning effect and efficiency. The sliding connection design of the spray assembly 2 allows the cleaning process to be automated or semi-automated to a certain extent. Compared with traditional manual cleaning methods, it reduces the workload and labor intensity of manual operation. In some large-scale pulping mold cleaning scenarios, this automated cleaning method can significantly improve production efficiency and reduce labor costs. At the same time, reducing human intervention also reduces the problem of unstable cleaning quality caused by human factors and improves the consistency of cleaning effect. The inlet of the inlet pipe 4 is used to connect high-pressure water or high-pressure air. This design allows the cleaning device to flexibly select the cleaning medium according to the specific situation of the pulping mold. For some stubborn stains, high-pressure water can wash away the stains with its strong impact force; while for some sticky substances or situations that require rapid drying, high-pressure air can remove moisture and impurities by blowing. By flexibly switching cleaning media, it is possible to better adapt to the cleaning needs of different molds and improve the cleaning effect.

[0035] Furthermore, the pulping mold cleaning device also includes a three-pipe connector 5, the first inlet of which is connected to high-pressure water, the second inlet of which is connected to high-pressure air, and the outlet of which is connected to the inlet of the inlet pipe 4.

[0036] Based on the above scheme, the three-way connector 5 is equipped with two inlets, one for high-pressure water and the other for high-pressure air. This allows the device to flexibly select either high-pressure water or high-pressure air as the cleaning medium when cleaning the pulping mold, depending on the actual contamination level and cleaning requirements of the mold. The design of the three-way connector 5 makes the cleaning device more convenient to operate. Operators can easily switch or combine cleaning media by simply adjusting the valves or connections on the three-way connector 5 according to the specific cleaning task, without the need for frequent changes of different cleaning equipment or pipeline connections as with traditional cleaning devices. This saves cleaning time and operating steps, and improves the efficiency of the cleaning work.

[0037] Furthermore, the pulping mold cleaning device also includes a control component, a regulating water valve 10 and a regulating air valve 6. The regulating water valve 10 is installed at the first inlet of the three-way pipe 5, and the regulating air valve 6 is installed at the second inlet of the three-way pipe 5. The regulating water valve 10 and the regulating air valve 6 are electrically connected to the control component.

[0038] The water regulating valve 10 is used to control the opening and closing of the water and to adjust the flushing air volume. The air regulating valve 6 is used to control the opening and closing of the air and to adjust the flushing air volume.

[0039] Based on the above scheme, the control component is electrically connected to the regulating water valve 10 and the regulating air valve 6, enabling the device to automatically adjust according to a preset program or the specific contamination status of the mold. For example, based on the degree of contamination in different areas of the mold, the control component can automatically adjust the opening of the water and air valves, eliminating the need for frequent manual operation, improving cleaning efficiency and stability, and reducing errors caused by human factors. Precise control of water and air flow rates avoids resource waste. For instance, water and air consumption can be reduced in lightly contaminated areas, while the flow rate can be appropriately increased in heavily contaminated areas. Simultaneously, a suitable flow rate ratio allows water and air to achieve the best cleaning effect, avoiding incomplete cleaning or damage to the mold due to improper flow rates, and extending the mold's service life.

[0040] Furthermore, the bracket 1 includes a fixing plate 12 and a fastener. The fastener is fixedly connected to one end of the fixing plate 12. The fastener includes a mounting plate 11, a connecting plate 15, and a support plate 13. The mounting plate 11, the connecting plate 15, and the support plate 13 are perpendicular to each other and fixedly connected to each other.

[0041] Based on the above scheme, the mounting plate 11, connecting plate 15, and support plate 13 are perpendicular to each other and fixedly connected to form a stable three-dimensional frame structure. The pulping mold cleaning device is subjected to various forces during the cleaning process, such as the impact force of water flow, gas pressure, and the weight of its own components. This mutually perpendicular and fixed structure can effectively disperse and bear these forces, making the support 1 more stable as a whole, less prone to deformation or shaking, thereby ensuring the stability and reliability of the entire cleaning device during operation.

[0042] Furthermore, the pulping mold cleaning device also includes a guide rail 7 and a fixed spray arm 8. The guide rail 7 is fixedly connected to the fixed plate 12, and the spray assembly 2 includes a sliding spray arm 21.

[0043] The sliding spray arm 21 and the fixed spray arm 8 are spaced apart along the extension direction of the guide rail 7. The sliding spray arm 21 is slidably connected to the guide rail 7, and the fixed spray arm 8 is fixedly connected to the fixed plate 12. The inlet of the fixed spray arm 8 is used to connect high-pressure water or high-pressure air, and the outlet of the fixed spray arm 8 is used to clean the pulping mold.

[0044] Based on the above scheme, the sliding spray arm 21 and the fixed spray arm 8 are spaced apart along the extension direction of the guide rail 7, and the sliding spray arm 21 is slidably connected to the guide rail 7. This allows the fixed spray arm 8 to stably clean specific areas of the mold during cleaning, while the sliding spray arm 21 can move along the guide rail 7 to clean different positions of the mold. Compared to a single spray arm, it can cover a larger cleaning range, avoid cleaning dead spots, and improve the comprehensiveness and effectiveness of cleaning. The sliding connection method of the sliding spray arm 21 gives the cleaning device greater flexibility. In the actual cleaning process, the position of the sliding spray arm 21 can be flexibly adjusted according to factors such as the specific shape of the mold and the distribution of stains. For example, for areas with more stains on the mold surface, the sliding spray arm 21 can be moved to that area for focused cleaning; for complex-shaped parts, the position of the spray arm can also be adjusted to achieve a better cleaning effect, making the cleaning process more in line with the actual situation of the mold.

[0045] Furthermore, the pulping mold cleaning device also includes a sliding plate, with the sliding spray arm 21 fixedly connected to the sliding plate, and the sliding plate fixedly connected to the guide rail 7.

[0046] Based on the above solution, the sliding spray arm 21 is connected to the guide rail 7 via a sliding plate. The sliding plate provides a larger contact area and a more stable connection structure. Compared to the sliding spray arm 21 being directly connected to the guide rail 7, the sliding plate can more evenly distribute the force on the sliding spray arm 21 during movement, reducing shaking or jamming caused by excessive local force. This allows the sliding spray arm 21 to slide more smoothly and steadily on the guide rail 7, ensuring the stability and continuity of the cleaning process and improving the consistency of the cleaning effect. The sliding plate also makes the installation and disassembly of the sliding spray arm 21 more convenient. In actual production and maintenance, when the sliding spray arm 21 needs to be inspected, repaired, or replaced, simply remove the sliding plate from the guide rail 7 to easily remove the sliding spray arm 21 along with it, without requiring complex operations on the guide rail 7.

[0047] Furthermore, the pulping mold cleaning device also includes a cylinder 9, which is fixedly connected to the fixed plate 12. The output shaft of the cylinder 9 is connected to the sliding spray arm 21, and the cylinder 9 is electrically connected to the control component.

[0048] Based on the above scheme, since cylinder 9 is controlled by the control component, the entire cleaning process can be automated. Before cleaning begins, the operator can set the motion parameters of cylinder 9, such as extension / retraction speed and stroke, in the control component according to the specific conditions of the pulping mold and the cleaning requirements. During the cleaning process, the control component automatically controls the extension / retraction of the output shaft of cylinder 9 according to the set program, driving the sliding spray arm 21 to clean according to the predetermined trajectory and rhythm. This not only improves cleaning efficiency but also reduces manual intervention, lowers cleaning errors caused by human factors, and ensures that the quality and effect of each cleaning are consistent. The electrical connection between cylinder 9 and the control component enables better coordination between the various components of the pulping mold cleaning device. The control component can adjust the movement of cylinder 9 in real time based on the working status and feedback information of other components. For example, when the water pressure or air pressure of the spray component 2 changes, the control component can adjust the extension / retraction speed of the output shaft of cylinder 9 accordingly to ensure that the movement of the sliding spray arm 21 matches the supply of the cleaning medium, thereby improving the cleaning effect. In addition, this connection method allows the device to better adapt to the cleaning needs of different types and sizes of pulping molds, and to achieve personalized cleaning solutions by adjusting control parameters.

[0049] Furthermore, the bracket 1 also includes a pipe fixing frame 14, which is spaced apart from the fixing plate 12. The connecting pipe 4 is fixedly connected to the pipe fixing frame 14 to connect to the bracket 1.

[0050] Based on the above solution, the pipe fixing bracket 14, as a supporting structure for the access pipe 4, can share the pressure and weight borne by the access pipe 4. Under the action of high-pressure water or high-pressure gas, the access pipe 4 will be subjected to certain impact forces and pressures. Without sufficient support, the access pipe 4 may be deformed or damaged. The reinforcement effect of the pipe fixing bracket 14 can effectively reduce the stress on the access pipe 4, improve its load-bearing capacity, and extend the service life of the access pipe 4.

[0051] Furthermore, the pulping mold cleaning device also includes a first rotary joint 101 and a second rotary joint 102. The first rotary joint 101 is installed between the outlet of the inlet pipe 4 and the inlet of the connecting hose 3, and the second rotary joint is installed between the outlet of the connecting hose 3 and the inlet of the spray assembly 2.

[0052] Based on the above scheme, the first rotary joint 101 is installed between the outlet of the inlet pipe 4 and the inlet of the connecting hose 3, and the second rotary joint 102 is installed between the outlet of the connecting hose 3 and the inlet of the spray assembly 2. During the cleaning process of the pulping mold, due to the cleaning action and the structural characteristics of the mold, relative rotation or angular changes may occur between the inlet pipe 4, the connecting hose 3, and the spray assembly 2. The first rotary joint 101 and the second rotary joint allow the connecting hose 3 to rotate freely within a certain range, effectively avoiding damage to the connecting hose 3 caused by relative movement, ensuring smooth flow of the cleaning medium, and improving the reliability and stability of the device.

[0053] The working process of this utility model is as follows: First, in the preparation stage, all components of the pulping mold cleaning device are installed and debugged, the lower forming mold and the upper forming mold are ready, and the high-pressure water and high-pressure air supply sources are connected to the pulping mold cleaning device. At the same time, the flushing water volume and air volume standards are set according to the degree of contamination of the pulp of different products. Next, the pulp scooping and product transfer stage begins. After the lower forming mold descends to the pulp tank to complete the pulp scooping, it rises again, and the upper forming mold immediately transfers the product to the hot pressing station. Subsequently, after the upper forming mold transfers the product, the pulping mold cleaning device starts to operate. The operator or control system adjusts the regulating water valve 10 and the regulating air valve 6 through the control components according to the severity of the contamination to control the opening and flow rate of water or air. If high-pressure water cleaning is used, water flows through the first inlet of the three-way connector 5, the inlet pipe 4, and the connecting hose 3 to the sliding spray arm 21 and is sprayed out. The water is then sprayed out through the fixed spray arm 8, where the first rotary joint 101 and the second rotary joint 102 ensure smooth water flow. If high-pressure air is used, air flows through the second inlet of the three-way connector 5, the inlet pipe 4, and the connecting hose 3 to the sliding spray arm 21 and is sprayed out through the fixed spray arm 8. Simultaneously with the water or air supply, the cylinder 9 drives the sliding plate to move along the extension direction of the guide rail 7, causing the sliding spray arm 21 to reciprocate and thoroughly clean the mold surface. After the spray connector assembly completes cleaning, the control component closes the regulating water valve 10 and the regulating air valve 6, stopping the water or air supply. The cylinder 9 then drives the sliding plate and the sliding spray arm 21 back to their initial positions. The lower and upper forming molds can then continue with the next round of production. The entire device is ready for the next cleaning task, and this cycle repeats continuously to ensure the surface of the pulping mold remains clean, guaranteeing product quality and production efficiency.

[0054] In summary, this utility model embodiment provides a pulping mold cleaning device. Its spray assembly 2 is slidably connected to the support 1. The connecting hose 3, in conjunction with the guide rail 7 and the sliding spray arm 21, allows the spray assembly 2 to move flexibly on the support 1, enabling comprehensive and multi-angle cleaning of the pulping mold, avoiding cleaning dead spots, and improving cleaning effect and efficiency. The sliding connection design of the spray assembly 2 allows the cleaning process to be automated or semi-automated to a certain extent. Compared with traditional manual cleaning methods, it reduces the workload and labor intensity of manual operation. In some large-scale pulping mold cleaning scenarios, this automated cleaning method can significantly improve production efficiency and reduce labor costs. At the same time, reducing human intervention also reduces the problem of unstable cleaning quality caused by human factors, improving the consistency of cleaning effect. The inlet of the inlet pipe 4 is used to connect high-pressure water or high-pressure air. This design allows the cleaning device to flexibly select the cleaning medium according to the specific conditions of the pulping mold. For some stubborn stains, high-pressure water can wash away the stains with its powerful impact; while for some sticky substances or situations requiring rapid drying, high-pressure air can remove moisture and impurities by blowing. By flexibly switching cleaning media, it is possible to better adapt to the cleaning needs of different molds and improve the cleaning effect.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
