Description

Technical Field

[0001] This utility model relates to the field of raw material tape technology, and in particular to an oil removal device for raw material tape production and processing. Background Technology

[0002] PTFE tape, also known as raw material tape, is an auxiliary product commonly used in the installation of liquid pipelines. It is mainly used at pipe joints to enhance the airtightness of the pipe joints. During the production of raw material tape, it is necessary to perform degreasing treatment. In the degreasing treatment, the raw material tape is generally passed through a heating roller area. The heating roller heats the raw material tape, causing the grease in it to evaporate, thus achieving the degreasing effect. However, as the oil evaporates, it cools and collects on the top wall of the device. Over time, this accumulation can cause oil to fall onto the raw material tape. Since the outer shell of the device is usually one piece, it is not convenient to clean, which can easily affect the degreasing effect. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing devices, where the outer shell is generally one piece, making cleaning difficult and affecting the degreasing effect. Therefore, this invention proposes a degreasing device for raw material tape production and processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an oil removal device for raw material tape production and processing, including a housing, with multiple heating rollers rotatably connected to the housing via bearings, a sealing strip connected to the upper opening of the housing, a cover abutting against the sealing strip, the cover moving via a moving mechanism, a suction fan fixedly connected to the cover, a connecting cylinder connected to the suction fan, and multiple ventilation pipes connected to the connecting cylinder, the multiple ventilation pipes communicating with the cover.

[0006] Preferably, the sealing strip is made of nitrile rubber.

[0007] Preferably, the moving mechanism includes a hydraulic rod, which is fixedly connected to the housing, and the cover is fixedly connected to the hydraulic rod. A slider is provided at the lower end of the hydraulic rod, and the slider is slidably mounted on a slide rail, which is fixedly connected to the housing.

[0008] Preferably, a threaded rod is threaded through the slider, and the threaded rod is rotatably connected to the housing via a bearing.

[0009] Preferably, the plurality of heating rollers are electric heating rollers.

[0010] Preferably, a collection tank is fixedly connected to the cover, and a return oil pipe is connected to the collection tank. A connecting cover is provided inside each of the plurality of ventilation pipes. The connecting cover and the ventilation pipe form a drip-proof cavity, and the drip-proof cavity is connected to the return oil pipe.

[0011] Preferably, the collection tank is equipped with a valve.

[0012] The present invention proposes an oil removal device for raw material strip production and processing, which has the following advantages: the cover is moved periodically by a moving mechanism to expose the lower surface of the cover, thereby cleaning the oil droplets on the cover and preventing the oil droplets from accumulating and dripping onto the raw material, thus ensuring the oil removal effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1: Refer to Figure 1-3 An oil removal device for raw material tape production and processing includes a housing 13. Multiple heating rollers 9 are rotatably connected to the housing 13 via bearings. The multiple heating rollers 9 are electric heating rollers. The heating rollers 9 evaporate the oil on the raw material tape passing through, thereby achieving the function of oil removal. A conveying roller 10 is rotatably connected to the housing 13 via bearings. The raw material tape is wound up by a winding device, thereby driving the raw material tape to move through the heating area.

[0020] A sealing strip is connected to the opening at the upper end of the housing 13. The sealing strip forms a rectangular structure and abuts against the cover 1. The cover 1 is moved by a moving mechanism. A suction fan 4 is fixedly connected to the cover 1. A connecting cylinder 2 is connected to the suction fan 4. Multiple ventilation pipes 3 are connected to the connecting cylinder 2 and are connected to the cover 1. By using the suction fan 4, the gas containing oil fumes is extracted. When it is necessary to clean the top wall of the housing, the cover 1 is periodically moved by the moving mechanism to expose the lower surface of the cover 1, thereby cleaning the oil droplets on the cover 1 and preventing the oil droplets from accumulating and dripping onto the raw material, thus ensuring the oil removal effect.

[0021] The sealing strip is made of nitrile rubber, which has good oil resistance.

[0022] The moving mechanism includes a hydraulic rod 5, which is fixedly connected to the housing 13. A cover 1 is fixedly connected to the hydraulic rod 5. A slider 8 is provided at the lower end of the hydraulic rod 5. The slider 8 is slidably mounted on a slide rail 6, which is fixedly connected to the housing 13. A threaded rod 7 is threaded through the slider 8. The threaded rod 7 is rotatably connected to the housing 13 via a bearing. When the hydraulic rod 5 extends, the threaded rod 7 is rotated, causing the slider 8 to slide on the slide rail 6, thereby moving the position of the cover 1 and opening the device.

[0023] Example 2: Refer to Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, a collection tank 12 is fixedly connected to the cover 1, and an oil return pipe 11 is connected to the collection tank 12. A connecting cover 14 is provided in each of the multiple ventilation pipes 3. The connecting cover 14 and the ventilation pipe 3 form an anti-drip cavity. The anti-drip cavity is connected to the oil return pipe 11. Oil droplets sliding down from the inner wall of the ventilation pipe 3 will enter the anti-drip cavity. By using the oil return pipe 11, the oil can be recovered and enter the collection tank 12 for recycling and reuse.

[0024] A valve is connected to the collection tank 12 so that it can be opened to drain the oil.

[0025] During operation, the heating roller 9 evaporates the oil, and the suction fan 4 extracts the oil-containing gas. When cleaning is required, the hydraulic rod 5 extends, the threaded rod 7 rotates, and the slider 8 slides on the slide rail 6, thereby moving the position of the cover 1 and opening the device to clean the lower surface of the cover 1.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
