Description

Technical Field

[0001] This utility model relates to the field of sealing roller technology, specifically a split-type sealing roller for a cotton collecting machine. Background Technology

[0002] The cotton collecting machine in a mineral wool production line operates in a relatively sealed space. Hot slag melt is centrifuged to form fibers, with 65% cotton fibers forming a primary felt. The high-speed centrifugal fiber-forming process produces some byproducts—slag balls. These slag balls have a particle size of 2-5mm, are vitreous, and have a Mohs hardness between 5-6.5. The standard cotton fiber-slag ball content is less than 10%. Both cotton fibers and slag balls are blown away from the centrifuge simultaneously. Because the slag balls are relatively denser than cotton fibers, the blowing distance is shorter. However, the triangular cotton collecting machine, to ensure maximum cotton collecting area, requires the sealing roller to be positioned as low as possible for slag and fiber separation. To ensure effective sealing, the two ends of the sealing roller must be placed outside the collecting machine casing, occupying a large space. Replacement requires extensive dismantling of surrounding structures, wasting labor time and increasing maintenance costs. Utility Model Content

[0003] The purpose of this invention is to provide a split-type sealing roller for a cotton collecting machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a split-type sealing roller for a cotton collecting machine, comprising:

[0005] A roller, which is a cavity with openings on both sides, has a fixing ring fixed to both sides of the inner wall of the roller, and a screw is fixed to one side of the fixing ring;

[0006] A roller shaft is placed inside the roller cylinder. A movable end face is detachably installed on the outer side of the roller shaft. The outer diameter of the movable end face is larger than the inner diameter of the fixed ring. The movable end face has a through hole that mates with a screw rod. One end of the screw rod passes through the through hole and is threadedly connected to a nut.

[0007] Preferably, bearing housings are installed at both ends of the roller.

[0008] Preferably, the roller shaft has a water conveying chamber 1 and a water conveying chamber 2 inside, and a water connection hole 1 is opened on the roller shaft at the position corresponding to the position of the water conveying chamber 1, and a water connection hole 2 is opened on the roller shaft at the position corresponding to the position of the water conveying chamber 2.

[0009] Preferably, a plurality of screws are fixedly connected to one side of the movable end face, a pressure plate is fixedly connected to the outside of the roller shaft, and one end of the screw passes through the middle of the pressure plate and is threadedly connected to a nut.

[0010] Preferably, a sealing gasket is installed on one side of the fixed ring and between the movable end face and the pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The roller and roller shaft are designed as separate units, eliminating the need for complete replacement when a local malfunction occurs. Only the damaged parts need to be repaired or replaced, reducing maintenance costs and equipment downtime, and improving maintainability and economy. During assembly, the roller is placed outside the roller shaft, and the movable end face is pushed inward from both sides of the roller shaft. After the screw passes through the through hole of the movable end face, the movable end face is fixed to the roller shaft via a key connection, and then locked with a nut. This assembly method is simple to operate, and the components are firmly connected, ensuring the stability of the equipment during operation. The screw on the movable end face side passes through the pressure plate and, in conjunction with the nut, tightly secures the movable end face, pressure plate, and fixing ring together, enhancing the overall structural strength and stability, and enabling it to withstand larger workloads.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , 2As shown in Figures 3 and 4, this utility model provides a technical solution: a split-type cotton collecting machine sealing roller, comprising: a roller 7, the roller 7 being a cavity with openings on both sides, a fixing ring 8 fixedly connected to both sides of the inner wall of the roller 7, and a screw 9 fixedly connected to one side of the fixing ring 8; a roller shaft 1 having a stepped shaft structure, the roller shaft 1 being placed inside the roller 7, and a movable end face 4 being connected to the outer side of the roller shaft 1 by a key, the outer diameter of the movable end face 4 being larger than the inner diameter of the fixing ring 8, the movable end face 4 having a through hole that mates with the screw 9, and a nut being threadedly connected to one end of the screw 9 through the through hole.

[0019] It should be noted that during assembly in this embodiment, the roller 7 is placed outside the roller shaft 1, and then the movable end face 4 is pushed inward from both sides of the roller shaft 1. When the screw 9 passes through the middle of the movable end face 4, the movable end face 4 moves to the corresponding boss structure and is connected to the roller shaft 1 by a key connection. This completes the connection between the movable end face 4 and the roller shaft 1, avoiding the need to replace the entire belt due to partial functional failure.

[0020] In one embodiment, bearing housings 11 are installed at both ends of the roller 1.

[0021] It should be noted that in this embodiment, the bearing housing 11 provides a solid support for the roller 1, ensuring that the roller 1 can rotate stably in its working environment without generating excessive vibration or deviation.

[0022] In one embodiment, the roller 1 has a water delivery chamber 10 and a water delivery chamber 12 inside. The roller 1 has a water connection hole 2 at the position corresponding to the water delivery chamber 10 and a water connection hole 3 at the position corresponding to the water delivery chamber 12.

[0023] It should be noted that, in this embodiment, both ends of the roller shaft 1 are provided with holes that communicate with the first water delivery chamber 10 and the second water delivery chamber 12. The roller shaft 1 is connected to both ends of the roller shaft 1 through a rotary joint, so that the liquid enters the roller 7 through the first water delivery chamber 10 and the first water connection hole 2. After the roller 7 is filled, it enters the second water delivery chamber 12 through the second water connection hole 3, and then exits through one end of the second water delivery chamber 12. In this way, cooling water can be circulated inside according to actual needs to reduce the roller surface temperature and delay the slagging on the roller surface.

[0024] In one embodiment, a plurality of screws 5 are fixedly connected to one side of the movable end face 4, and a pressure plate 6 is fixedly connected to the outside of the roller 1. One end of the screw 5 passes through the middle of the pressure plate 6 and is threadedly connected to a nut.

[0025] It should be noted that, in this embodiment, the end of the pressure plate 6 is a boss structure. Bolts for pressing and fixing are installed on the boss structure in a direction perpendicular to the roller shaft 1. The pressure plate 6 is fitted and installed on one side of the movable end face 4, so that both screw 5 and screw 9 pass through the middle of the pressure plate 6. Nuts are threaded onto the ends of both screw 5 and screw 9, thereby tightly fixing the movable end face 4, the pressure plate 6 and the fixing ring 8 together.

[0026] In one embodiment, a sealing gasket is installed on one side of the retaining ring 8 and between the movable end face 4 and the pressure plate 6.

[0027] It should be noted that in this embodiment, the sealing gasket effectively prevents fluid leakage under pressure or movement. It is located at the connection between the fixed ring 8 and the movable end face 4 and the pressure plate 6, ensuring the sealing of these components and guaranteeing that cooling water will not overflow.
