Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric manufacturing technology, specifically to an opening and feeding transfer device. Background Technology

[0002] Non-woven fabrics, due to their moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic, and odorless properties, are widely used in various fields, such as in the production of masks, surgical gowns, medical dressings, and sterilization wraps. Their non-toxic, odorless, and breathable characteristics make them important in medical supplies. In agriculture, non-woven fabrics are mainly used to protect the growth of vegetables, flowers, and other plants susceptible to weather conditions. They also possess heat-insulating properties, providing warmth in areas with large diurnal temperature variations. Furthermore, non-woven fabrics have good moisture retention capabilities, reducing the frequency of watering and lowering costs and labor. They also have wide applications in industry, decoration, and clothing.

[0003] The production of nonwoven fabrics requires different raw materials with varying proportions depending on the intended use, followed by a blending and opening process. The resulting fluffy raw material is then fed into the subsequent web-forming equipment. Because the opened fluffy raw material is almost fibrous, it is not suitable for open feeding, and therefore typically uses a closed-pipe suction conveying system. The conveyor requires a transfer structure to connect to the main feed pipe.

[0004] Existing opening and feeding transfer devices for nonwoven fabric manufacturing are prone to clogging, requiring manual opening of windows for unblocking. This allows external dust to easily enter the transfer device, reducing the quality of the finished product and increasing the labor intensity of workers. Therefore, in view of this, an opening and feeding transfer device is proposed to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes an opening and feeding transfer device to solve the technical problem mentioned in the background art, which is that existing opening and feeding transfer devices used for nonwoven fabric manufacturing are prone to blockage, requiring manual opening of windows for unblocking, which allows external dust to easily enter the transfer device, reducing the quality of the finished product and increasing the labor intensity of workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cotton opening and feeding adapter, comprising:

[0007] An adapter housing, wherein a connecting cylinder is provided at one end of the adapter housing and a connecting flange is provided at the other end;

[0008] There are two sets of gripping plates arranged opposite each other, and multiple sets of gripping hooks are provided on their opposite surfaces. Both sets of gripping plates are arranged in the adapter shell and can move in a circumferential direction, and the two sets of gripping plates move in opposite directions.

[0009] A crank handle, rotatably mounted on the adapter housing; and

[0010] A drive mechanism is disposed on the adapter housing and connected to the crank handle and the two sets of gripping plates to convert the movement of the crank handle into the simultaneous movement of the two sets of gripping plates.

[0011] Furthermore, the drive mechanism includes:

[0012] The mounting shafts are provided in at least four sets, and each set of the mounting shafts is rotatably mounted on the adapter housing. Each set of the mounting shafts is provided with a rocker arm.

[0013] The connecting sleeves, having the same number of sets as the mounting shafts, are all hinged to the ends of the rocker arm. Every two sets of the connecting sleeves are fixedly connected to one set of the gripping plates.

[0014] A linkage component is connected to two of the sets of mounting shafts to drive the two sets of mounting shafts to rotate in opposite directions.

[0015] Furthermore, each end of the mounting shaft is provided with a synchronous pulley, and the two sets of synchronous pulleys connected to each set of grippers are connected by a synchronous belt.

[0016] Furthermore, the linkage component includes two sets of gears, which are respectively fixedly installed at the bottom of a set of mounting shafts corresponding to the two sets of grippers, and the two sets of gears mesh with each other.

[0017] Furthermore, a sealing strip is also provided on one side of the connecting flange.

[0018] Furthermore, the adapter shell is provided with a transparent observation window.

[0019] Furthermore, the grab hooks on one side of the two sets of grab plates are arranged in a staggered manner.

[0020] Furthermore, the gripper plate is connected to the side wall of the adapter shell by a tension spring.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] When in use, the connecting cylinder is connected to the opening machine, and the connecting flange is connected to the main cotton feeding pipe. The lint after being opened by the opening machine is sucked and moved into the main cotton feeding pipe through the transfer shell. When the transfer shell is blocked, the crank handle can be turned. During the rotation of the crank handle, the drive mechanism controls two sets of gripping plates to move in opposite directions in a circular motion. Through the movement of the two sets of gripping plates and the opening and closing of multiple sets of hooks, the lint at the blockage in the transfer shell is grabbed and transported into the main cotton feeding pipe, thereby effectively preventing the transfer device from becoming blocked. It also eliminates the need for manual window opening for treatment, effectively preventing external dust from entering the transfer device and reducing the labor intensity of the workers.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0030] Example:

[0031] like Figure 1As shown, this utility model provides an opening and feeding transfer device, including a transfer shell 1, a connecting cylinder 2 at one end of the transfer shell 1, and a connecting flange 3 at the other end. A sealing strip 4 is also provided on one side of the connecting flange 3, and a transparent observation window 5 is provided on the transfer shell 1. In use, the connecting cylinder 2 can be connected to the opening machine, and the connecting flange 3 can be connected to the feeding pipe. The sealing strip 4 increases the sealing between the connecting flange 3 and the feeding pipe. The state of the fibrous material inside the transfer shell 1 can be observed through the observation window 5, and the blockage can be cleared in time.

[0032] like Figure 2 , 3 As shown, in this embodiment, there are also two sets of oppositely arranged gripping plates 12. The opposite surfaces of the two sets of gripping plates 12 are provided with multiple sets of gripping hooks 14. Both sets of gripping plates 12 are circumferentially movable inside the adapter shell 1, and the movement directions of the two sets of gripping plates 12 are opposite. A crank handle 11 is rotatably provided on the adapter shell 1. A drive mechanism connected to the crank handle 11 and the two sets of gripping plates 12 is provided on the adapter shell 1. The drive mechanism converts the movement of the crank handle 11 into driving the two sets of gripping plates 12 to move simultaneously.

[0033] The drive mechanism includes at least four sets of mounting shafts 6, which are rotatably mounted on the adapter housing 1. Each set of mounting shafts 6 is equipped with a rocker arm 7, and each set of gripping plates 12 is equipped with two sets of connecting sleeves 13, which are hinged to the ends of the rocker arms 7. The ends of the mounting shafts 6 are equipped with synchronous pulleys 8, and the two sets of synchronous pulleys 8 connected to each set of gripping plates 12 are connected by a synchronous belt 9.

[0034] When one set of mounting shafts 6 is rotated by shaking the handle 11, the other set of mounting shafts 6 is driven to rotate by the synchronous wheel 8. During the synchronous rotation of the two sets of mounting shafts 6, the rocker arm 7, mounting shafts 6 and gripper plate 12 can form a parallelogram structure, thereby controlling the gripper plate 12 to move in a parallel circumferential direction.

[0035] like Figure 2 , 3 As shown, in this embodiment, the drive mechanism further includes a linkage assembly connected to two sets of mounting shafts 6, which drives the two sets of mounting shafts 6 to rotate in opposite directions. The linkage assembly includes two sets of gears 10, which are respectively fixedly mounted at the bottom of a set of mounting shafts 6 corresponding to the two sets of gripping plates 12, and the two sets of gears 10 mesh with each other.

[0036] When one set of mounting shafts 6 rotates, it controls the other set of mounting shafts 6 to move in the opposite direction through the meshing of two sets of gears 10. This causes the hooks 14 in the two sets of gripping plates 12 to open and close relative to each other, so as to grab the lint and transport it into the cotton feeding pipe, thereby clearing the transfer device. The hooks 14 on one side of the two sets of gripping plates 12 are staggered to avoid collision. The gripping plates 12 are connected to the side wall of the transfer shell 1 by a tension spring 15. After clearing, the crank handle 11 is released, and the two sets of gripping plates 12 are reset and moved to both sides of the transfer shell 1 under the action of the tension spring 15. No manual reset is required, which prevents the gripping plates 12 from interfering with the transport of lint.

[0037] The specific usage and beneficial effects of this utility model are as follows:

[0038] When in use, the connecting cylinder 2 is connected to the opening machine, and the connecting flange 3 is connected to the main cotton feeding pipe. The lint after being opened by the opening machine is sucked and moved into the main cotton feeding pipe through the transfer shell 1. When the transfer shell 1 is blocked, the crank handle 11 can be turned. During the rotation of the crank handle 11, the two sets of gripping plates 12 are controlled by the drive mechanism to make opposite circumferential movements. Through the movement of the two sets of gripping plates 12 and the opening and closing of multiple sets of gripping hooks 14, the lint at the blockage in the transfer shell 1 is grabbed and transported into the main cotton feeding pipe, thereby effectively preventing the transfer device from being blocked. It also eliminates the need for manual window opening for treatment, effectively preventing external dust from entering the transfer device and reducing the labor intensity of the workers.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
