Description

Technical Field

[0001] This utility model belongs to the field of bar processing technology, specifically relating to a negative pressure bar dewatering machine. Background Technology

[0002] During the production process, the mixed raw materials need to be extruded into strips of plastic material by a screw extruder. Since the temperature of the masterbatch after extrusion by the screw extruder is very high and the strips are in a high-temperature state, they need to be cooled and cured by a cooling water tank.

[0003] Some strip-shaped materials (hereinafter referred to as strips) require a water-cooling process during shaping. During water cooling, the strips need to be in full contact with water, resulting in a significant amount of water adhering to them. To facilitate subsequent winding and storage, the water on the strips needs to be separated. Currently, most methods rely on vibration during strip movement to detach the strips from the water, and water tanks are used to collect water dropped during movement. However, some water adhering to the strips exists as a water film on the strip surface, which is difficult to separate from the strip. This results in water stains remaining on the wound strips. Therefore, this application proposes a negative pressure strip dewatering machine. Utility Model Content

[0004] The purpose of this invention is to provide a negative pressure strip dewatering machine to solve the problem mentioned in the background art. Currently, most existing methods rely on vibration during the movement of the strip to separate it from the water, and a water tank is set up to collect the water that falls off the strip during the movement. However, some water adhering to the strip will exist on the surface of the strip in the form of a water film, which is not easy to separate from the strip. This results in water stains still adhering to the strip after it is wound up.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure strip dewatering machine, including a filter tank and a guide unit installed on the filter tank for guiding the movement of the strip. A protective unit is provided at the filter tank. When the strip moves, the protective unit presses on the upper side of the strip above the guide unit to prevent the strip from detaching from the guide unit. The filter tank is located below the material bar; A suction pipe is installed above the filter tank. The suction pipe is perpendicular to the direction of travel of the material strip. A duckbill tube is installed at the suction pipe to align with the material strip. The suction tube is provided with a main pipe that is connected to the main pipe and an air extraction device that is connected to the main pipe and used to provide suction force for the duckbill tube to extract gas.

[0006] Preferably, two guide units are provided, and the two guide units are distributed in parallel on the water filter tank.

[0007] Preferably, the guide unit includes a round rod and a mounting base that rotatably engages with the round rod, the mounting base being installed on the water filter tank.

[0008] Preferably, the round rod is provided with a plurality of limiting rings, and a limiting groove for the feed bar to pass through is formed between two adjacent limiting rings.

[0009] Preferably, the limiting ring and the round rod can be fixed by welding.

[0010] Preferably, the limiting ring and the round rod are connected by a thread.

[0011] Preferably, the protective unit includes a support frame installed on the water filter tank, a support base installed on the support frame, and an opening and closing plate that rotates with the support base. A rotating shaft is inserted into the support base and is fixedly connected to the opening and closing plate. A power motor is installed on the support frame, and the output shaft of the power motor is connected to the rotating shaft. The power motor is installed on the support frame, and the output shaft of the power motor and the rotating shaft are connected by a coupling.

[0012] Preferably, there are two suction pipes, and the two suction pipes are symmetrically distributed.

[0013] Preferably, the filter pool is inclined downward along the direction of material movement, and the end of the filter pool is provided with a guide port that tapers inward. A water storage pool is provided at the bottom of the filter pool, and the guide port is aligned with the water storage pool.

[0014] Preferably, the air extraction device includes a drain outlet connected to a water storage tank.

[0015] Beneficial effects: I. The present invention provides a negative pressure strip dewatering machine, which guides the movement of the strip through a guiding unit. A protective unit is set at the filter tank. The power motor in the protective unit can drive the rotating shaft and the opening and closing plate to rotate, which in turn drives the pressure plate to rotate. When the pressure plate presses on the strip, it can press on the top of the limiting groove, blocking the channel for the strip to detach from the limiting groove. This allows the strip to move only along the limiting groove, thus preventing the strip from detaching from the guiding unit during the conveying process.

[0016] 2. The suction device can provide suction to the suction pipe to draw in gas. At the end of the suction pipe, a duckbill tube is set, which is aligned with the material strip and distributed perpendicular to the direction of the material strip's movement. This forms an airflow that moves towards the suction pipe. The opening of the duckbill tube is smaller than the internal channel of the suction pipe. Therefore, the wind speed at the duckbill tube is increased. The increase in wind speed can accelerate the rate at which water vapor on the material strip is removed and accelerate the drying rate of the material strip. Attached Figure Description

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1-5 As shown in the figure, the present invention provides a negative pressure strip dewatering machine, including a water filter tank 4 and a guide unit 2 installed on the water filter tank 4 for guiding the movement of the strip 1. After the strip 1 is water-cooled and formed, water adheres to its outer surface. The water filter tank 4 is located on the path of the strip 1 and is used to collect the water that falls on the surface of the strip 1 during its movement. The guide unit 2 is used to guide the movement of the strip 1, so that the strip 1 can move within a specified range and avoid misalignment of the strip 1.

[0021] It should be noted that there are two guide units 2, and the two guide units 2 are distributed in parallel on the water filter tank 4.

[0022] Specifically, the guide unit 2 includes a round rod 201 and a mounting base that rotatably engages with the round rod 201. The mounting base is installed on the water filter tank 4. The round rod 201 is provided with several limiting rings 202. A limiting groove 203 for the feed bar 1 to pass through is formed between two adjacent limiting rings 202. In one specific embodiment, the limiting rings 202 and the round rod 201 can be fixed by welding. In another embodiment, the limiting rings 202 and the round rod 201 are connected by threads. The limiting rings 202 can be rotated, and the position of the limiting rings 202 can be adjusted through the threads. This allows for fine-tuning according to the movement path of the feed bar 1, enabling the guide to adapt to various paths of the feed bar 1.

[0023] To prevent the material strip 1 from falling off the guide unit 2 during movement, a protective unit 3 is installed at the water filter tank 4. The protective unit 3 includes a support frame 301 installed on the water filter tank 4, a support base 302 installed on the support frame 301, and an opening and closing plate 303 that rotatably engages with the support base 302. A rotating shaft is inserted into the support base 302 and is fixedly connected to the opening and closing plate 303. A power motor is installed on the support frame 301, and the output shaft of the power motor is connected to the rotating shaft. The power motor is installed on the support frame 301, and the output shaft of the power motor is connected to the rotating shaft through a coupling. The power motor can drive the rotating shaft and the opening and closing plate 303 to rotate, thereby driving the pressure plate 304 to rotate. When the pressure plate 304 presses on the material strip 1, it can press on the top of the limiting groove 203, blocking the channel for the material strip 1 to detach from the limiting groove 203. This allows the material strip 1 to move only along the limiting groove 203, thus preventing the material strip 1 from detaching from the guide unit 2 during the conveying process.

[0024] At the same time, the opening and closing plate 303 can rotate in the opposite direction with the power motor, so that the pressure plate 304 and the limiting groove 203 can be separated. In this way, during the initial wire guiding process of the material strip 1, the upper limiting groove 203 opens to facilitate the entry of the material strip 1 and facilitate the wire guiding operation.

[0025] It should be noted that the water filter tank 4 is located below the material bar 1.

[0026] During the movement of the material strip 1, some of the water on it will fall into the filter tank 4, but some will still adhere to the outer surface of the material strip 1. In order to remove this water, a suction pipe 5 is installed above the filter tank 4. The suction pipe 5 is perpendicular to the direction of travel of the material strip 1. A duckbill pipe 6 is installed at the suction pipe 5 to align with the material strip 1. There are two suction pipes 5, and the two suction pipes 5 are symmetrically distributed.

[0027] Specifically, the suction pipe 5 is equipped with a main pipe 7 and an air extraction device 8 connected to the main pipe 7 and used to provide suction force to the duckbill tube 6 to draw gas. The air extraction device 8 can provide suction force to the suction pipe 5 to draw gas. At the end of the suction pipe 5, the duckbill tube 6 is provided, aligned with the material strip 1 and distributed perpendicular to the direction of travel of the material strip 1, forming an airflow that travels towards the suction pipe 5. The opening of the duckbill tube 6 is smaller than the internal channel of the suction pipe 5. Therefore, the wind speed at the duckbill tube 6 is increased. The increase in wind speed can accelerate the speed at which water vapor on the material strip 1 is removed and accelerate the drying speed of the material strip 1.

[0028] In order to collect the water that falls into the filter tank 4, the filter tank 4 is inclined downward along the direction of material bar 1, and the end of the filter tank 4 is provided with a guide port that tapers inward. The bottom of the filter tank 4 is provided with a water storage tank 9, and the guide port is aligned with the water storage tank 9.

[0029] It should be noted that the air extraction device 8 includes a drain outlet, which is connected to the water storage tank 9. This allows the moisture on the material strip 1 to be separated, facilitating subsequent recycling.

[0030] In summary, this utility model embodiment provides a negative pressure strip dewatering machine. The guide unit 2 guides the movement of the strip 1. A protective unit 3 is set at the filter tank 4. The power motor in the protective unit 3 can drive the rotating shaft and the opening and closing plate 303 to rotate, which in turn drives the pressure plate 304 to rotate. When the pressure plate 304 presses on the strip 1, it can press on the top of the limiting groove 203, blocking the channel for the strip 1 to detach from the limiting groove 203. This allows the strip 1 to move only along the limiting groove 203, thus preventing the strip 1 from detaching from the guide unit 2 during the conveying process.

[0031] The suction device 8 can provide suction to the suction pipe 5 to draw in gas. At the end of the suction pipe 5, a duckbill tube 6 is provided, which is aligned with the material strip 1 and distributed perpendicular to the direction of travel of the material strip 1, forming an airflow that travels toward the suction pipe 5. The opening of the duckbill tube 6 is smaller than the internal channel of the suction pipe 5. Therefore, the wind speed at the duckbill tube 6 is increased. The increase in wind speed can accelerate the speed at which water vapor on the material strip 1 is removed and accelerate the drying speed of the material strip 1.

[0032] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
