Description

Technical Field

[0001] The utility model generally relates to the technical field of fiber material production, and more specifically relates to a fiber roller cleaning device and fiber material production equipment. Background Art

[0002] At present, there are various methods for preparing continuous fiber reinforced thermoplastic unidirectional prepreg tapes, including melt impregnation, solution impregnation, powder impregnation, fiber blending, in-situ polymerization impregnation, fiber-film hot pressing, etc. Among them, melt impregnation is the most widely used and most industrially realized manufacturing method. This process mainly involves the glass fiber drawn out from the yarn spreading system, which comes into contact with the high-temperature thermoplastic resin extruded from the impregnation die head device, and then undergoes heating impregnation, pressurization, cooling, slitting, winding and other process processes to compound the fiber and resin into a thermoplastic prepreg unidirectional tape with a certain thickness and smooth surface.

[0003] In this process, whether the glass fiber can be evenly and stably unfolded is an important factor affecting the quality of the thermoplastic prepreg unidirectional tape. Since the glass fiber raw yarn used is composed of hundreds or even thousands of monofilaments, the diameter of the monofilament is several microns to more than twenty microns. Due to the presence of waste silk in the glass fiber bundle and the high specific surface energy of the monofilament, these monofilaments are easily entangled on the roller during the unfolding process, causing the glass fiber bundle to unfold unevenly or even break, so tools are needed to clean the entangled glass fiber. Generally, when glass fiber entanglement occurs, it is mainly through workers cutting it off section by section with sharp tools such as blades, and then cleaning the glass fiber by hand, which is not only time-consuming and labor-intensive, inefficient, but also poses a safety hazard.

[0048] Figure 1A cleaning device for a fiber over-roller 110 is shown. The cleaning device includes a fixing frame 120, a cutting knife 130, and a wire winding assembly 140. The cutting knife 130 is movably arranged relative to the fixing frame 120 in a first direction D1 parallel to the axial direction of the fiber over-roller 110, and the cutting knife 130 is used to abut against the fiber over-roller 110. The wire winding assembly 140 includes a rubber roller 141, and the rubber roller 141 is rotatably arranged relative to the fixing frame 120 around a first rotation axis AX1 parallel to the first direction D1, and the rubber roller 141 is used to abut against the fiber over-roller 110.

[0049] According to the cleaning device for the fiber over-roller 110 of the present utility model, when the cutting knife 130 moves in the first direction D1, it can cut the fiber 100 wound on the fiber over-roller 110, and then the rubber roller 141 adsorbs and collects the fiber 100 on the fiber over-roller 110, thereby realizing the cleaning of the impurity fiber 100 on the fiber over-roller 110. The cleaning efficiency is high, and there is no need for manual cleaning, and the safety is high.

[0050] As Figure 1 can be seen, the fiber 100 in normal production bypasses the fiber over-roller 110 from below the fiber over-roller 110, and the fiber over-roller 110 can rotate along a third rotation axis AX3, so as to guide and convey the bypassed fiber 100. And the cutting knife 130 is arranged above the fiber over-roller 110, so that the cutting knife 130 can be prevented from cutting the fiber 100 in normal production.

[0051] Optionally, referring to Figure 1 , the cleaning device further includes a reciprocating driving assembly 150. The reciprocating driving assembly 150 is arranged on the fixing frame 120 and connected to the cutting knife 130 to make the cutting knife 130 reciprocate in the first direction D1, so that the cutting knife 130 can cut the fiber 100 on the fiber over-roller 110. In addition, by using the reciprocating driving assembly 150 to drive the cutting knife 130, the fiber 100 on the fiber over-roller 110 can be fully cut, preventing the omission of fiber 100 impurities.

[0052] Optionally, referring to Figure 1 , the fixing frame 120 includes a first frame body 121, a second frame body 122, and an elastic member 127 (not shown in the figure). The first frame body 121 is connected to the reciprocating driving assembly 150. Along a second direction D2 perpendicular to the first direction D1, the second frame body 122 is fixed relative to the fiber over-roller 110. The elastic member 127 is arranged between the first frame body 121 and the second frame body 122, and the elastic member 127 is configured to apply an elastic force towards the fiber over-roller 110 to the first frame body 121 along the second direction D2, so that the cutting knife 130 connected to the first frame body 121 through the reciprocating driving assembly 150 has an acting force towards the fiber over-roller 110, so that the cutting knife 130 can effectively cut the impurity fiber 100 on the fiber over-roller 110 and improve the cutting success rate of the cutting knife 130.

[0053] Further, referring to Figure 1 , along the second direction D2 (i.e., the vertical direction), the first frame 121 is movably connected to the second frame 122 between the avoidance position and the working position. The cutter 130 on the first frame 121 at the avoidance position is spaced apart from the fiber roller 110. As Figure 1 shown, the cutter 130 on the first frame 121 at the working position abuts against the fiber roller 110. The fixing frame 120 further includes a first fastener 123, and the first fastener 123 is respectively connected to the first frame 121 and the second frame 122, and is used to fix the first frame 121 at the avoidance position relative to the second frame 122. Then, after the second frame 122 is installed, the first fastener 123 can be removed to release the first frame 121, so that the cutter 130 can abut against the fiber roller 110 to more effectively cut the fiber 100.

[0054] Specifically, the first fastener 123 passes through the second frame 122. The first frame 121 is provided with two fastening holes at intervals along the second direction D2 corresponding to the avoidance position and the working position. When the first frame 121 is movably connected to the second frame 122 between the avoidance position and the working position, the first fastener 123 is threadedly connected to the corresponding two fastening holes to fix the first frame 121 and the second frame 122 together.

[0055] Furthermore, the fixing frame 120 further includes a base 125 and a second fastener 124. The base 125 is arranged at the bottom end of the second frame 122. The second fastener 124 passes through the base 125 and is used to connect the base 125 to structures such as the frame of the fiber material production equipment or the factory building foundation, so as to realize the installation of the fixing frame 120. In the actual installation of the fixing frame 120, first fix the first fixing frame 120 and the second fixing frame 120 through the first fastener 123. At this time, the elastic member 127 is in the maximum compression state. Then, fix the base 125 through the second fastener 124 so that the cutter 130 abuts against the fiber roller 110. Finally, remove the first fastener 123 so that the cutter 130 has a force towards the fiber roller 110, thereby realizing the installation of the fixing frame 120 and ensuring the cutting effect of the cutter 130 on the fiber 100.

[0056] Optionally, the first frame body 121 and the second frame body 122 are in a sleeve structure. A sleeve groove 126 with an upward opening is provided in the second frame body 122. The bottom end of the first frame body 121 penetrates into the sleeve groove 126, so that the first frame body 121 is connected to the second frame body 122 in a penetrating manner along the second direction D2, and thus the first frame body 121 is movably arranged relative to the second frame body 122. The elastic member 127 is arranged in the sleeve groove 126. The upper end of the elastic member 127 is connected to the bottom end of the first frame body 121, and the lower end of the elastic member 127 is connected to the inner bottom surface of the sleeve groove 126, thereby reducing the interference of the external environment and making the performance of the fixing frame 120 more stable.

[0057] Optionally, the elastic member 127 can be a spring or an elastic element such as a rubber block.

[0058] Optionally, the cleaning device includes two fixing frames 120. The two fixing frames 120 are spaced apart along the first direction D1, and the cleaning roller is arranged between the two fixing frames 120.

[0059] Further, referring to Figure 1 , the reciprocating driving assembly 150 includes a moving block 151, a driving member 152, and a driving rod 153. The moving block 151 is connected to the cutting knife 130. The driving member 152 is arranged on the fixing frame 120. Specifically, the driving member 152 is arranged on the first frame body 121. The driving rod 153 is connected to the moving block 151 along the first direction D1 and is connected to the driving member 152. The driving rod 153 is configured to be driven by the driving member 152 to drive the moving block 151 to reciprocate along the first direction D1, so as to drive the cutting knife 130.

[0060] Optionally, the reciprocating driving assembly 150 further includes a guide rod 154. The guide rod 154 is fixed to the fixing frame 120 and penetrates into the moving block 151 along the first direction D1, so that the moving block 151 can move relative to the fixing frame 120 along the first direction D1. The driving rod 153 is configured as a reciprocating lead screw and penetrates into the moving block 151. The driving rod 153 is threadedly connected to the moving block 151. The driving member 152 is configured as a motor. Therefore, when the driving member 152 drives the driving rod 153 to rotate, the moving block 151 moves along the first direction D1 under the spiral propulsion of the driving rod 153, so that the cutting knife 130 can move along the first direction D1, and the transmission is stable, and the cutting knife 130 can be effectively driven.

[0061] As an alternative solution, the driving rod 153 is fixed to the moving block 151, and the driving member 152 is configured as a linear driving element. For example, the driving member 152 is a hydraulic pipe or an electric push rod. Therefore, when the driving member 152 drives the driving rod 153, it can directly push the moving block 151 to move along the first direction D1, and can also drive the cutting knife 130.

[0062] Optionally, the take-up assembly 140 further includes a rotating frame 142. The rotating frame 142 is rotatably connected to the fixed frame 120 about a second rotation axis AX2 parallel to the first direction D1 and is disposed above the fiber passing roller 110. The rubber roller 141 is rotatably connected to the rotating frame 142 about the first rotation axis AX1. Thus, the rubber roller 141 is pressed against the fiber passing roller 110 under the action of gravity. The electrostatic adsorption effect on the roller surface of the rubber roller 141 can collect the fibers 100 cut and broken on the fiber passing roller 110, eliminating the need for manual collection, ensuring high safety, and preventing the fibers 100 from falling, thus maintaining the cleanliness of the processing environment.

[0063] The present utility model also provides a fiber material production device, including a fiber passing roller 110 and a cleaning device for the fiber passing roller 110 as described above. According to the fiber material production device of the present utility model, impurities on the fiber passing roller 110 can be efficiently cleaned, and the safety is high.
