Description

Technical Field

[0001] This utility model relates to the field of fiber drying technology, and in particular to a fiber drying production line. Background Technology

[0002] Fiber drying is a key process that removes moisture from fibers to meet the needs of subsequent processing or storage. Therefore, existing fiber drying equipment, such as the one disclosed in CN220135921U, involves closing the material hopper, connecting two handles, starting a hot air blower to raise the internal temperature to a specified value, and then allowing the fibers to be dried to enter the hopper through the feed pipe until the fibers are observed to reach a suitable height through the observation window. The motor is then started to rotate the hopper and the fibers. After drying, the motor is controlled to move the sliding door to the point closest to the drawer and stop rotating, deconnecting the two handles. Pushing the sliding door handle away from the other handle allows the fibers to leave the hopper and enter the drawer near the bottom of the hopper. The drawer is then pulled out, and the fibers are poured into a designated storage container.

[0003] However, existing equipment uses a single material hopper as the core component, with a fixed capacity, and can only process a fixed amount of fiber at a time. It cannot achieve uninterrupted processing of large quantities of fiber like a production line through continuous feeding and segmented drying. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a fiber drying production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fiber drying production line, comprising a belt conveyor for fiber feeding, a drying shell for fiber drying, and a receiving box for fiber discharge after drying. A guide channel extending into the drying shell is installed at the end of the belt conveyor frame. A coaxially distributed annular channel is rotatably connected to the drying shell near the belt conveyor. Several annularly arrayed discharge ports are opened on the side of the annular channel, and a drying cylinder is provided at each discharge port. The drying cylinders are arranged in an annular array around the central axis of the annular channel, and the central axis of the drying cylinders is parallel to the central axis of the annular channel. The drying cylinder wall is open, and a heat-insulating ring is rotatably connected to the drying cylinder wall. A feeding frame is fixedly installed through the surface of the heat-insulating ring. An insert plate is inserted into the feeding frame near the heat-insulating ring. A spring rod is provided between the insert plate and the feeding frame. The receiving box is located near the bottom of the drying shell, and several drying cylinders inside the drying shell pass through the receiving box sequentially. The receiving box is inserted through the surface of the drying shell, and the box wall is used to abut against the insert plate.

[0006] Preferably, a second toothed ring is fixedly installed on the outer wall of the annular channel, and a second gear is provided inside the drying shell, which is driven by a motor and meshes with the second toothed ring.

[0007] Preferably, both sides of the drying shell are hollowed out at the same height as the receiving box, and the two hollowed-out areas are respectively used for the receiving box and the insert plate to pass through. A lead screw is rotatably connected to the surface of the drying shell near the hollowed-out area of ​​the receiving box. The lead screw is arranged parallel to the central axis of the drying cylinder and is threadedly connected to the wall of the adjacent receiving box.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figures 1-5 As shown, a fiber drying production line includes a belt conveyor for fiber feeding, a drying shell for fiber drying, and a receiving box for dried fiber discharge. A guide channel extending into the drying shell is installed at the end of the belt conveyor frame. A coaxially distributed annular channel is rotatably connected inside the drying shell near the belt conveyor. A coaxially distributed second toothed ring is fixedly installed on the outer wall of the annular channel. A second gear, driven by a motor and meshing with the second toothed ring, is installed inside the drying shell. In actual use, the second gear is driven by a motor installed inside the drying shell, which in turn drives the meshing second toothed ring to rotate the annular channel. Because the guide channel extends into the annular channel, the fibers transported by the belt conveyor will directly enter the annular channel under the guidance of the guide channel. Figure 5As shown, the sides of the annular channel are set with bevels, so the fibers entering the annular channel will automatically slide towards the discharge port at the bottom of the annular channel; the sides of the annular channel have several discharge ports arranged in an annular array and each discharge port is equipped with a drying cylinder. The fibers accumulated at the bottom discharge port in the annular channel will automatically enter the corresponding connected drying cylinder for drying. Several drying cylinders are arranged in a circular array around the central axis of an annular channel, with the central axis of the drying cylinders parallel to the central axis of the annular channel. The cylinder walls are open, and heat-insulating rings are rotatably connected to the cylinder walls. A feeding frame is fixedly installed through the surface of the heat-insulating rings. An insert plate is inserted into the feeding frame near the heat-insulating ring. A spring rod is installed between the insert plate and the feeding frame. Under normal circumstances, the spring rod ensures that the insert plate is in the closed state of the feeding frame. Because the heat-insulating ring is rotatably connected to the cylinder wall, in conjunction with the weight of the feeding frame, as the annular channel drives the several drying cylinders to revolve, the heat-insulating ring on its surface will automatically rotate under the gravity of the feeding frame and always keep the feeding frame facing downward. The receiving box is located near the bottom of the drying shell, and several drying cylinders inside the drying shell pass through the receiving box sequentially. The receiving box is inserted through the surface of the drying shell, and the box wall is used to abut against the insert plate. Both sides of the drying shell, at the same height as the receiving box, are hollowed out, with two openings for the receiving box and the insert plate to pass through respectively. A lead screw is rotatably connected to the surface of the drying shell near the hollowed-out area containing the receiving box. The lead screw is parallel to the central axis of the drying cylinder and threadedly connected to the wall of the adjacent receiving box. In actual use, the lead screw is driven to rotate by a motor installed outside the drying shell, thus achieving the connection between the lead screw and the cylinder. The receiving box with the threaded connection is horizontally inserted into the drying shell. During the process of replenishing fibers into the drying cylinder located at the bottom of the drying shell, the fibers in the adjacent drying cylinder are dried. The receiving box is horizontally inserted into the drying shell and pushes the insert plate to move and open against the tension of the spring rod. The slid-open insert plate extends out of the drying shell through the hollowed-out part on the other side. The dried fibers in the drying shell fall into the receiving box through the opened insert plate of the feeding frame. The bottom of the receiving box is set with a slope, so the dried fibers that fall into the receiving box will slide out of the drying shell along the receiving box.

[0019] A fixed ring is rotatably connected to the inner wall of the annular channel on the side away from the belt conveyor. A discharge port is also opened at the bottom edge of the outer side of the fixed ring, and a fixed frame connected to the inner wall of the drying shell is fixedly installed on the inner side of the fixed ring. The fixed frame ensures that the fixed ring will not rotate. Since a discharge port is also opened at the bottom of the surface of the fixed ring, when the drying cylinder rotates to the discharge port that is detached from the surface of the fixed ring, the discharge port of the annular channel connected to the drying cylinder can be blocked by the fixed ring, preventing the fibers inside the drying cylinder from entering the annular channel from the discharge port during the rotation of the drying cylinder.

[0020] The drying cylinder includes connecting discs at both ends. One connecting disc is fixedly connected to the discharge port, and its center is offset from the discharge port. The two ends of the insulation ring are rotatably connected to the opposite ends of the two connecting discs. Several heating plates are fixedly mounted on the surface of the other connecting disc. A connecting frame is fixedly mounted on the side of the heating plates near the annular channel. The rotation of the annular channel drives the connected disc to rotate synchronously. The surface of the connecting frame is rotatably connected to the center of the connecting disc on the discharge port side. This rotational connection with the connecting frame drives the heating plates and the other connecting disc fixedly connected to the heating plates to rotate synchronously. This achieves the revolution of the two connecting discs as the annular channel rotates around the central axis of the drying shell. A first gear, coaxially distributed, is fixedly mounted on the center of the other connecting disc away from the annular channel. A similar gear is fixedly mounted on the inner wall of the drying shell. The first gear ring, which is distributed on the shaft and meshes with the first gear, and the other connecting disc, during their revolution, will rotate due to the rotational connection between the connecting frame and the connecting disc near the annular channel. Therefore, the heating plate connected to it will rotate around the central axis of the drying shell, thereby agitating the internal fibers. The heating plate used in this solution generates heat by means of a built-in electric heating wire. The extension of the other connecting disc is fitted with a connecting arm that is fixedly connected to the annular channel. The connecting arm ensures that the other connecting disc rotates synchronously around the central axis of the drying shell during the rotation of the annular channel. And because the connecting arm is fitted with the central extension of the other connecting disc, it will not affect its rotation during the revolution.

[0021] The method of using this utility model is as follows: The belt conveyor transports the fibers to be dried to the end of the frame. The fibers enter the rotating annular channel through the guide channel. The motor drives the second gear to rotate, and the meshing of the second gear ring drives the annular channel to rotate around the central axis. The inclined structure of the annular channel causes the fibers to slide towards the bottom discharge port. The fixing ring blocks the non-bottom discharge port, and the fibers automatically enter the drying cylinder corresponding to the bottom discharge port, completing the material distribution.

[0022] The annular channel drives several drying cylinders to revolve around its central axis. The heating plates of the drying cylinders are energized and generate heat. When the drying cylinders revolve, the first gear at its end meshes with the first toothed ring fixed to the inner wall of the drying shell, causing the drying cylinders to rotate. The heating plates agitate the internal fibers to achieve uniform drying. During this process, the heat preservation ring keeps the feeding frame facing downwards due to its own weight. The insert plate closes the feeding frame under the action of the spring rod to prevent fiber leakage. At the same time, the heat preservation ring reduces heat loss from the drying cylinders.

[0023] During the process of pouring fibers into the bottom drying cylinder, the motor drives the lead screw to rotate, causing the receiving box to be inserted horizontally into the drying shell. The wall of the receiving box abuts against the insert plate of the corresponding drying cylinder's feeding frame, overcoming the tension of the spring rod and pushing the insert plate open. The dried fibers fall into the receiving box through the feeding frame and slide out of the drying shell along the inclined surface of the receiving box. After the receiving box finishes discharging, it resets, and the annular channel continues to rotate. Subsequent drying cylinders pass through the receiving box in sequence to complete the discharge, while new fibers continuously enter the empty drying cylinders, achieving continuous drying.

[0024] The wiring diagrams of the belt conveyor, motor, and heating plate in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the belt conveyor, motor, and heating plate will not be explained in detail.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
