Fiber cloth sizing and drying equipment

Abstract

This utility model provides a fiber cloth sizing and drying device, including a drying box. One end of the drying box has an inlet, and the other end has an outlet. The fiber cloth enters the drying box through the inlet and exits through the outlet. Guide wheels are provided on the inner sides of both the inlet and outlet. Two vertically opposing moving mechanisms are symmetrically arranged inside the drying box. An upper moving seat and a lower moving seat, which move vertically respectively, are driven and mounted on the upper and lower moving seats inside the drying box. By providing vertically opposing upper and lower moving seats inside the drying box, and installing an upper roller mechanism and a lower roller mechanism on them respectively, when it is necessary to thread the cloth, the upper and lower moving seats can be controlled to move towards each other through a drive mechanism, creating a gap between the upper and lower roller mechanisms for the fiber cloth to pass horizontally. This eliminates the need for manual winding of the cloth between the upper and lower rollers, avoiding the difficulty of threading cloth using traditional fixed rollers.

Description

Technical Field

[0001] This utility model relates to the field of fiber cloth processing, and in particular to a fiber cloth sizing and drying equipment. Background Technology

[0002] In the production and processing of fiber cloth, sizing and drying are key processes, especially for high-performance fiber materials such as diabase fiber cloth. Their surfaces need to be uniformly coated with sizing agent and thoroughly dried to enhance subsequent processing performance and the mechanical properties of the final product. To ensure drying effectiveness, existing drying equipment typically employs multiple rollers arranged alternately inside the drying chamber. This allows the fiber cloth to travel through the chamber in a multi-folded pattern, thereby extending its residence time in the high-temperature environment and improving heat exchange efficiency and drying uniformity.

[0003] However, in practical applications, most of these rollers are fixed structures, requiring the fiber cloth to be routed around each upper and lower roller individually during the fabric threading process, which is extremely inconvenient. Especially when changing batches or re-threading the fabric after maintenance, manual traction and positioning of the fiber cloth segment by segment is required, which is not only time-consuming and labor-intensive but also prone to wrinkling, shifting, or even damage due to improper tension control, affecting production efficiency and product quality. Therefore, a fiber cloth sizing and drying device is proposed to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a fiber cloth sizing and drying equipment to solve the problem of time-consuming and labor-intensive fiber cloth passing through the upper and lower rollers in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a fiber cloth sizing and drying device, including a drying box, with an inlet at one end and an outlet at the other end. The fiber cloth enters the drying box through the inlet and exits through the outlet. Guide wheels are provided on the inner sides of both the inlet and outlet. Two vertically opposing moving mechanisms are symmetrically arranged inside the drying box. Upper and lower moving seats that move vertically are respectively mounted on the upper moving mechanisms. Multiple upper roller mechanisms located below the fiber cloth are arranged between the two upper moving seats, and multiple lower roller mechanisms located above the fiber cloth are arranged between the two lower moving seats. The lower roller mechanisms and the upper roller mechanisms are arranged alternately. Through the vertical movement of the upper and lower roller mechanisms, the fiber cloth that passes horizontally through the drying box is bent into a multi-folded shape. A drive mechanism for simultaneously driving the two vertically opposing moving mechanisms is also provided on the top of the drying box.

[0006] In the preferred embodiment, the upper and lower opposing moving mechanism includes a rotatable forward and reverse threaded rod and two limiting slide rods. The back of both the upper moving seat and the lower moving seat is provided with an internal threaded sleeve and two limiting slide sleeves. The internal threaded sleeve is threaded onto the corresponding threaded section, and the two limiting slide sleeves are slidably fitted onto the two limiting slide rods respectively.

[0007] In the preferred embodiment, the lower roller mechanism has the same structure as the upper roller mechanism and is symmetrically distributed vertically with the fiber cloth as the central axis. Specifically, it includes two L-shaped extension frames, and rollers are rotatably arranged between the ends of the two L-shaped extension frames.

[0008] In the preferred embodiment, the L-shaped extension frame is provided with a movable groove, in which an elastic tension part is installed, and rollers are rotatably arranged between the elastic tension parts.

[0009] In a preferred embodiment, the elastic tension part includes a movable seat movably mounted in the movable groove. The movable seat has sliding grooves on both sides and slides with the side wall of the movable groove. The movable seat is equipped with a bearing for rotating the mounting roller. The bottom of the movable seat is provided with a screw that movably extends out of the movable groove. A telescopic spring is fitted on the outside of the screw between the movable seat and the bottom wall of the movable groove. A nut is threaded onto the protruding end of the screw.

[0010] In the preferred embodiment, the drive mechanism includes two support shaft seats located on the top of the drying chamber. A transmission rod is rotatably mounted in each of the two support shaft seats. A transmission bevel gear is mounted at the disjoint end of each of the two transmission rods. Driven bevel gears are mounted on the top of the positive and negative threaded rods of the two opposing vertical moving mechanisms, passing through the drying chamber. The driven bevel gears mesh with the corresponding transmission bevel gears. A drive motor is also located on the top of the drying chamber. A dual-output reducer is driven and connected to the output shaft of the drive motor. The two output shafts of the dual-output reducer are respectively connected to the two transmission rods.

[0011] In the preferred embodiment, a plurality of heating tubes are connected to one side of the drying oven. The heating tubes are Y-shaped, with two parallel air outlets connected to the drying oven and the other air inlet connected to a hot air output device.

[0012] In the preferred embodiment, the top of the drying oven is equipped with multiple exhaust vents.

[0013] In the preferred embodiment, the drying oven is also equipped with an opening and closing door on the side.

[0014] This invention provides a fiber cloth sizing and drying device. It features an upper and lower movable seat that can move vertically in opposite directions inside the drying chamber, with an upper roller mechanism and a lower roller mechanism installed on each. When cloth needs to be threaded through, a drive mechanism controls the upper and lower movable seats to move in opposite directions, creating a gap between the upper and lower roller mechanisms for the fiber cloth to pass horizontally. This eliminates the need for manual winding of the cloth between the rollers, allowing the diabase fiber cloth to pass through the drying chamber quickly and smoothly, significantly improving threading efficiency and reducing the labor intensity of operators. The drive mechanism moves the upper and lower movable mechanisms in opposite directions, causing the upper and lower roller mechanisms to move in coordination, bending the horizontally threaded fiber cloth into a multi-folded shape. This avoids the difficulty of threading cloth using traditional fixed rollers, extending the cloth's running path and dwell time within the drying chamber, improving the heat exchange efficiency between hot air and the fiber cloth, ensuring uniform drying, and allowing for adjustment of the degree of bending.

[0025] like Figure 1-8 As shown, a fiber cloth sizing and drying device includes a drying chamber 1. One end of the drying chamber 1 is provided with a feed inlet 2, and the other end is provided with a discharge outlet 3. The fiber cloth enters the drying chamber 1 through the feed inlet 2 and exits through the discharge outlet 3. Guide wheels 4 are provided on the inner side of both the feed inlet 2 and the discharge outlet 3. The guide wheels 4 play a limiting and guiding role after the fiber cloth is bent in the drying chamber 1, preventing it from directly contacting the feed inlet 2 or the discharge outlet 3. The guide wheels 4 are specifically set on the upper or lower side of the feed inlet 2 or the discharge outlet 3 according to the bending situation of the fiber cloth. This is a common technical means in the field, so it will not be described in detail here.

[0026] Furthermore, two vertically opposing moving mechanisms 6 are symmetrically arranged inside the drying chamber 1. Upper moving seats 8 and lower moving seats 7, which move vertically, are driven and mounted on the vertically opposing moving mechanisms 6 respectively. Multiple upper roller mechanisms 10, located below the fiber cloth, are arranged between the two upper moving seats 8, and multiple lower roller mechanisms 9, located above the fiber cloth, are arranged between the two lower moving seats 7. In this embodiment, there are two upper roller mechanisms 10 and two lower roller mechanisms 9, which are arranged alternately with the upper roller mechanisms 10. Through the vertical movement of the upper roller mechanisms 10 and lower roller mechanisms 9, the fiber cloth horizontally passing through the drying chamber 1 is bent into a multi-folded shape. The initial state of the upper roller mechanisms 10 and lower roller mechanisms 9 is visible. Figure 8 As shown, a gap is formed between the two to allow the fiber cloth to pass through horizontally. The top of the drying box 1 is also provided with a drive mechanism 11 for simultaneously driving the two vertically opposing moving mechanisms 6, thereby ensuring that the two vertically opposing moving mechanisms 6 can operate synchronously.

[0027] This design allows the fiber cloth to pass through the drying box 1 in a horizontal state. After the fiber cloth posture is determined, the fiber cloth is bent into a multi-fold line shape by the up and down movement of the upper roller mechanism 10 and the lower roller mechanism 9, as well as the cooperation of the take-up and put-out devices at both ends of the drying box 1, thereby realizing the automatic bending of the fiber cloth.

[0028] In the preferred embodiment, the upper and lower opposing moving mechanism 6 includes a rotatable forward and reverse threaded rod 601 and two limiting slide rods 602. The forward and reverse threaded rod 601 is located between the two limiting slide rods 602 and is rotatably mounted in the drying chamber 1 via bearings. The back of both the upper moving seat 8 and the lower moving seat 7 is provided with an internal threaded sleeve 802 and two limiting slide sleeves 801. The internal threaded sleeve 802 is threaded onto the corresponding threaded section, and the two limiting slide sleeves 801 are slidably mounted on the two limiting slide rods 602 respectively.

[0029] With this design, the upper moving seat 8 and the lower moving seat 7 can be moved toward opposite or opposite sides by rotating the forward and reverse threaded rods 601 and limiting the two limiting slide rods 602.

[0030] In the preferred embodiment, the lower roller mechanism 9 has the same structure as the upper roller mechanism 10 and is symmetrically distributed vertically with the fiber cloth as the central axis. Specifically, it includes two L-shaped extension frames 901. Through the shape characteristics of the L-shaped extension frames 901, the rollers 902 can be located on the upper and lower sides of the fiber cloth respectively. The rollers 902 are rotatably arranged between the ends of the two L-shaped extension frames 901, so that the rollers 902 can move upward or downward under the action of the upper moving seat 8 and the lower moving seat 7, thereby bending the fiber cloth into a multi-fold line shape.

[0031] Furthermore, the L-shaped extension frame 901 is provided with a movable groove 903, in which an elastic tension part 904 is installed. The roller 902 is rotatably disposed between the elastic tension parts 904. By providing the elastic tension parts 904, the rigid stretching of the fiber cloth during the bending process can be avoided, thus preventing unnecessary damage to the cloth.

[0032] In a preferred embodiment, the elastic tension part 904 includes a movable seat 9040 movably mounted in the movable groove 903. Sliding grooves 9041 are provided on both sides of the movable seat 9040 and slide in cooperation with the side wall of the movable groove 903, thereby enabling the movable seat 9040 to slide stably up and down. A bearing 9042 for rotating the mounting roller 902 is installed in the movable seat 9040. A screw 9043 is provided at the bottom of the movable seat 9040, extending movably through the movable groove 903. A through hole is provided at the bottom of the movable groove 903 for the screw 9043 to pass through. A telescopic spring 9044 is fitted around the screw 9043 between the movable seat 9040 and the inner bottom wall of the movable groove 903. A nut 9045 is threaded onto the protruding end of the screw 9043.

[0033] This design utilizes the elasticity provided by the telescopic spring 9044 to buffer the roller 902 during contact with the fiber cloth, preventing rigid tension during bending and thus avoiding unnecessary damage to the fiber cloth. In addition, the range and elasticity of the movable seat 9040 can be adjusted by the cooperation of the nut 9045 and the screw 9043.

[0034] In the preferred embodiment, the drive mechanism 11 includes two support shaft seats 1105 disposed on the top of the drying chamber 1. A transmission rod 1103 is rotatably disposed in both support shaft seats 1105. A transmission bevel gear 1104 is disposed at the disjoint ends of the two transmission rods 1103. The tops of the positive and negative threaded rods 601 of the two vertically opposing moving mechanisms 6 pass through the drying chamber 1 and are equipped with driven bevel gears 603. The driven bevel gears 603 mesh with the corresponding transmission bevel gears 1104. A drive motor 1101 is also disposed on the top of the drying chamber 1. A dual-output reducer 1102 is driven and connected to the output shaft of the drive motor 1101. The two output shafts of the dual-output reducer 1102 are respectively connected to the two transmission rods 1103.

[0035] With this design, the power output of the drive motor 1101 and the dual-output reducer 1102 can be used to drive the two transmission rods 1103 to rotate synchronously with the two transmission bevel gears 1104 respectively. Then, through the meshing relationship with the driven bevel gear 603 respectively, the synchronous adjustment of the two positive and negative threaded rods 601 can be achieved.

[0036] It should be noted that a protective housing may be provided on the outside of the drive mechanism 11.

[0037] In the preferred embodiment, a plurality of heating tubes 12 are connected to one side of the drying chamber 1. The heating tubes 12 are Y-shaped, with two parallel air outlets connected to the drying chamber 1 and another air inlet connected to a hot air output device. A flange for connection is provided on the air inlet. The hot air output device can be composed of a fan and a heating wire box. This is prior art in the field and will not be described in detail here. This achieves multi-point hot air supply inside the drying chamber 1.

[0038] In addition, the top of the drying chamber 1 is provided with multiple exhaust ports 13 for discharging the dried air.

[0039] In the preferred embodiment, the side of the drying oven 1 is also provided with an opening and closing door 14. The opening and closing door 14 is installed by a hinge, and a sealing strip is provided on the connection surface between the door and the drying oven 1. The opening and closing door 14 is also provided with a corresponding door lock. The drying oven 1 can be opened from the side through the opening and closing door 14, which facilitates the initial horizontal penetration of the fiber cloth and also facilitates the maintenance of the equipment inside.

That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
