A feeding device for a drying oven

Abstract

This application relates to a feeding device for a drying oven, including a frame and two rotating rollers. Each rotating roller is fitted with a water-absorbing layer for contacting the fabric. In use, the fabric passes through the gap between the two rotating rollers, and the water-absorbing layer contacts the fabric surface, absorbing moisture from the fabric surface. This reduces the moisture content of the fabric when it enters the drying oven, thereby reducing the drying time and energy consumption, and improving drying efficiency.

Description

Technical Field

[0001] This application relates to the field of drying equipment, and more particularly to a feeding device for a drying oven. Background Technology

[0002] Rayon fabric refers to artificial cotton, scientifically known as viscose fiber, which belongs to the category of man-made fibers. In the dyeing and finishing process of rayon fabric, color fixing is a key step to ensure the color stability of the fabric. Currently, the industry generally uses a wet steaming process for color fixing of rayon fabric.

[0003] After the wet steaming and color-fixing process, a large amount of moisture (including residual moisture from the process and washing) will adhere to the surface of the rayon fabric. A washing process is necessary to remove residual dyes, auxiliaries, and impurities from the fabric surface to prevent contamination and odor problems during subsequent processing or use. After washing, the fabric is usually dried in a drying oven. Before drying, the fabric is typically squeezed using a wringer to initially remove moisture.

[0004] While the aforementioned technologies address this issue, roller pressing can only remove some moisture, leaving a significant amount remaining in the fabric. When this type of fabric enters the dryer directly, more heat energy is required to evaporate the residual moisture, resulting in a significantly longer drying time and reduced drying efficiency. Utility Model Content

[0005] In order to reduce the moisture in the fabric and improve the drying efficiency, this application provides a feeding device for a drying box.

[0006] The feeding device for a drying oven provided in this application adopts the following technical solution: A feeding device for a drying oven includes a frame and two rotating rollers. The two rotating rollers are spaced apart by a gap for the fabric to pass through. The rotating rollers are rotatably connected to the frame. Each rotating roller is fitted with an absorbent layer for contacting the fabric.

[0007] By adopting the above technical solution, when in use, the fabric passes through the gap between the two rotating rollers, and the absorbent layer contacts the fabric surface to absorb the moisture on the fabric surface, thereby reducing the moisture content of the fabric when it enters the drying box, reducing the drying time and energy consumption, and improving drying efficiency.

[0008] Optionally, a squeezing roller is provided on the side of the rotating roller away from the fabric. The squeezing roller is connected to a pusher, which is used to push the squeezing roller against the absorbent layer.

[0009] By adopting the above technical solution, during use, the pusher pushes the squeezing roller to continuously press against the absorbent layer, squeezing out the water absorbed by the absorbent layer, thereby reducing the water in the absorbent layer and improving the water absorption effect of the absorbent layer.

[0010] Optionally, the frame is connected to a movable block, and the squeezing roller is connected to the frame through the movable block. The movable block has a sliding hole. The pushing component includes a spring and a slider. One end of the spring is connected to the inner wall of the sliding hole. The squeezing roller is connected to the slider. The spring drives the slider to slide and drives the squeezing roller to press against the water absorption layer.

[0011] By adopting the above technical solution, when in use, the spring drives the slider to move and drives the squeezing roller to press against the water-absorbing layer. In this way, the squeezing pressure can be adaptively adjusted according to the thickness change of the water-absorbing layer after water absorption, so as to avoid excessive squeezing pressure damaging the water-absorbing layer. At the same time, the contact area between the squeezing roller and the water-absorbing layer is increased, thereby improving the water squeezing effect.

[0012] Optionally, an installation sleeve is provided inside the absorbent layer, the absorbent layer is sleeved outside the installation sleeve, the installation sleeve is slidably sleeved on the rotating roller, and the rotating roller is connected to a locking member, the locking member being used to lock the installation sleeve to the rotating roller.

[0013] By adopting the above technical solution, when the absorbent layer ages or becomes sticky with impurities after long-term use, the installation sleeve and absorbent layer can be removed and replaced by releasing the locking part when disassembling the absorbent layer, thus facilitating the cleaning and replacement of the absorbent layer.

[0014] Optionally, a limiting groove is formed on the circumference of the rotating roller, the length direction of the limiting groove is consistent with the length direction of the rotating roller, a limiting block is connected to the inner wall of the mounting sleeve, the limiting block is inserted into the rotating roller through the limiting groove, and the limiting block slides along the length direction of the rotating roller and fits into the inner wall of the limiting groove.

[0015] By adopting the above technical solution, when in use, the limiting block and the limiting groove cooperate to restrict the circumferential rotation of the mounting sleeve, so that the periphery of the absorbent layer is in full contact with the fabric, thereby improving the water absorption effect.

[0016] Optionally, the locking component includes a fixing plate and a connecting plate. The fixing plate is connected to one end of the rotating roller along its length, and the connecting plate is threaded to the other end of the rotating roller. The mounting sleeve is fitted between the connecting plate and the fixing plate, and both ends of the absorbent layer are in contact with the connecting plate and the fixing plate, respectively.

[0017] By adopting the above technical solution, when in use, the mounting sleeve and the absorbent layer are located between the fixed plate and the connecting plate. Tightening the connecting plate can lock them in place. When disassembling, rotate the connecting plate and remove it from the rotating roller, and the mounting sleeve can be removed from the rotating roller, which facilitates the cleaning and replacement of the absorbent layer.

[0018] Optionally, a collection box is provided below the squeezing roller, the collection box is connected to the moving block, the length direction of the collection box is consistent with the length direction of the squeezing roller, and the top of the collection box is provided with an opening.

[0019] By adopting the above technical solution, the water squeezed out by the squeezing roller falls directly into the collection box below during use, minimizing water dripping and contaminating the equipment and workshop environment, and reducing subsequent cleaning workload.

[0020] Optionally, the movable block is slidably fitted to the frame, which is connected to a drive unit for moving the movable block and driving the squeezing roller and the collection box away from the rotating roller.

[0021] By adopting the above technical solution, when replacing the absorbent layer, the driving component moves the moving block, so that the squeezing roller and the collection box are away from the rotating roller, providing sufficient space for operation, thereby facilitating the disassembly and assembly of the absorbent layer.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, the fabric passes through the gap between the two rotating rollers, and the absorbent layer contacts the fabric surface to absorb the moisture on the fabric surface, thereby reducing the moisture content of the fabric when it enters the drying box, reducing the drying time and energy consumption, and improving drying efficiency. 2. During use, the pusher pushes the squeezing roller to continuously press against the absorbent layer, squeezing out the water absorbed by the absorbent layer, thereby reducing the water in the absorbent layer and improving the water absorption effect of the absorbent layer; 3. When in use, the mounting sleeve and the absorbent layer are located between the fixed plate and the connecting plate. Tightening the connecting plate will lock them in place. To disassemble, rotate the connecting plate and remove it from the rotating roller. The mounting sleeve can then be removed from the rotating roller, making it easier to clean and replace the absorbent layer. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a feeding device for a drying oven. (Refer to...) Figure 1 and Figure 2 A feeding device for a drying oven includes a frame 100 and rotating rollers 200. The rotating rollers 200 are rotatably connected to the frame 100, and their length direction is aligned with the fabric width direction. Two rotating rollers 200 are provided, and they are horizontally spaced apart on the frame 100 to form a gap for the fabric to pass through. A water-absorbing layer 210 is fitted onto the rotating roller 200, with its central axis collinear with the central axis of the rotating roller 200. The water-absorbing layer 210 is used to contact the fabric. A squeezing roller 300 is provided on the side of the rotating roller 200 that is horizontal and away from the fabric, and its length direction is aligned with the length direction of the rotating roller 200. The squeezing roller 300 is connected to the frame 100 via a moving block 500, with one end of its length direction connected to the moving block 500. The squeezing roller 300 is used to squeeze the water-absorbing layer 210. The absorbent layer 210 absorbs water from the fabric surface, reducing the fabric's moisture content and improving drying efficiency.

[0029] Reference Figure 2 and Figure 3 A mounting sleeve 220 is slidably fitted onto the rotating roller 200. The length direction of the mounting sleeve 220 is consistent with the length direction of the rotating roller 200, and the central axis of the mounting sleeve 220 is collinear with the central axis of the rotating roller 200. The absorbent layer 210 is connected to the rotating roller through the mounting sleeve 220 and is fixedly fitted onto the outside of the mounting sleeve 220. A limiting block 221 is connected to the inner wall of the mounting sleeve 220, and the length direction of the limiting block 221 is consistent with the length direction of the rotating roller 200. A limiting groove 230 is formed on the circumference of the rotating roller 200, and the length direction of the limiting groove 230 is consistent with the length direction of the rotating roller 200. The limiting block 221 is inserted into the rotating roller 200 through the limiting groove 230, and the limiting block 221 slides along the length direction of the rotating roller 200 and is fitted into the inner wall of the limiting groove 230.

[0030] Reference Figure 1 and Figure 2 The rotating roller 200 is connected to a locking element 400, which includes a fixing plate 410 and a connecting plate 420. The fixing plate 410 is sleeved on one end of the rotating roller 200 along its length. The connecting plate 420 is threaded onto the other end of the rotating roller 200. A mounting sleeve 220 is located between the connecting plate 420 and the fixing plate 410, with both ends of the mounting sleeve 220 contacting the connecting plate 420 and the fixing plate 410 respectively along its length. During disassembly, rotating the connecting plate 420 and removing the disassembly plate from the rotating roller 200 allows the mounting sleeve 220 and the absorbent layer 210 to be removed from the rotating roller 200 for cleaning or replacement.

[0031] Reference Figure 1 and Figure 2The frame 100 has a movable hole 110 for the movable block 500 to be inserted into, and the length direction of the movable hole 110 is consistent with the horizontal direction. The movable block 500 slides along the length direction of the movable hole 110 and engages with the inner wall of the movable hole 110. The frame 100 is connected to a driving component, which is a first cylinder 120. The length direction of the first cylinder 120 is consistent with the length direction of the movable hole 110. The cylinder body of the first cylinder 120 is connected to the frame 100, and the piston rod of the first cylinder 120 is connected to the movable block 500.

[0032] Reference Figure 1 and Figure 2 The movable block 500 has a sliding hole 510, the length of which is aligned with the length of the movable hole 110. A pusher 600 is installed inside the sliding hole 510. The pusher 600 includes a spring 610 and a slider 620. The length of the spring 610 is aligned with the length of the sliding hole 510. One end of the spring 610 is connected to the inner wall of the sliding hole 510, and the other end is connected to the slider 620. One end of the squeezing roller 300 is rotatably connected to the slider 620. The spring 610 drives the slider 620 to slide within the sliding hole 510, thereby causing the squeezing roller 300 to press against the absorbent layer 210. The spring 610 drives the squeezing roller 300 closer to the absorbent layer 210, allowing the squeezing roller 300 to adaptively adjust the squeezing pressure according to the thickness change of the absorbent layer 210 after water absorption, thus improving the squeezing effect.

[0033] Reference Figure 1 and Figure 2 A collection box 520 is connected below the squeezing roller 300. The length of the collection box 520 is the same as that of the squeezing roller 300, and the top of the collection box 520 is open. The collection box 520 is connected to the moving block 500. The top of the collection box 520, along its width and near the rotating roller 200, contacts the absorbent layer 210, and the top of the inner wall of the collection box 520 near the rotating roller 200 is inclined towards the side closest to the rotating roller 200. When the squeezing roller 300 squeezes the absorbent layer 210, the squeezed water is guided into the collection box 520 by the inner wall of the collection box 520, reducing the possibility of the squeezed water being reabsorbed by the absorbent layer 210.

[0034] The principle of the feeding device of the drying oven in this application embodiment is as follows: When in use, the fabric passes through the gap between the two rotating rollers 200, the water-absorbing layer 210 contacts the fabric surface, the water-absorbing layer 210 absorbs the moisture on the fabric surface, reduces the moisture content of the fabric, thereby reducing the time and energy consumption required for drying and improving drying efficiency.

[0035] Furthermore, when the absorbent layer 210 absorbs water from the fabric, the squeezing roller 300, under the action of the spring 610, presses against the absorbent layer 210, squeezing out the water in the absorbent layer 210, thereby reducing the water content in the absorbent layer 210 and improving the water absorption effect. The water squeezed out by the squeezing roller 300 falls into the collection box 520, thereby minimizing pollution to the surrounding environment.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
