Description

Technical Field

[0001] The utility model relates to a transmission shaft anti-entanglement device, in particular to a transmission shaft anti-entanglement device for a conveyor belt of a cocoon peeling machine. Background Art

[0002] Cocoon peeling is the process of removing the cocoon skin in the silk production process. The cocoon skin is a loose and messy layer of silk on the outside of the cocoon. The fiber is thin and fragile, and the sericin content is high. It cannot be reeled. Removing this part of the cocoon skin before reeling is beneficial to cocoon selection, cocoon boiling and reeling, and improves the quality of raw silk. The cocoon with the cocoon skin is called a hair cocoon, and the cocoon without the cocoon skin is called a bare cocoon. The existing cocoon peeling machine mostly uses two interconnected conveyor belts. With the assistance of the limit baffle, the cocoon is rubbed in the gap between the two conveyor belts with different speeds, causing the cocoon skin to peel off. The peeled cocoons are transferred to the next production link, and the peeled cocoon skin is collected by the conveyor belt. When the cocoon skin is accumulated too much on the conveyor belt, it is easy to stick out of the edge of the conveyor belt and get involved in the transmission shaft of the conveyor belt, which requires frequent cleaning and maintenance, affecting production efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an anti-entanglement device for the transmission shaft of the conveyor belt of a cocoon peeling machine.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: an anti-entanglement device for the transmission shaft of the conveyor belt of a cocoon peeling machine is installed on a frame provided with a cocoon peeling device, the cocoon peeling device includes a conveyor belt for adhering and peeling cocoon husks, and the frame is provided with cocoon husk guiding and cleaning strips on both sides of the conveyor belt, and the ends of the cocoon husk guiding and cleaning strips are pressed against the edges on both sides of the conveyor belt surface.

[0005] As a preferred technical solution, the cocoon guiding and cleaning strip is arc-shaped, the plane where the cocoon guiding and cleaning strip is located forms an angle with the surface of the conveyor belt, and the extension direction of the end of the cocoon guiding and cleaning strip forms an acute angle with the running direction of the conveyor belt.

[0006] As a preferred technical solution, the frame is provided with bolts and screw holes that cooperate with each other, the head of the cocoon guide cleaning strip is provided with a mounting ring, and the bolts pass through the mounting ring and the screw holes in sequence to be connected to the frame.

[0007] As a preferred technical solution, the mounting ring forms a certain angle with the plane where the cocoon casing guide cleaning strip is located.

[0008] Due to the adoption of the above technical scheme, when the cocoon peeling machine is in operation, when the conveyor belt surface with the peeled cocoon skins adhered to it passes through the cocoon skin guiding and cleaning strips, the ends of the cocoon skin guiding and cleaning strips squeeze and scrape the conveyor belt surface, so that the cocoon skin residues are kept away from the edge of the conveyor belt surface, thereby preventing them from winding around the driving shaft of the conveyor belt, effectively reducing the maintenance frequency and alleviating the maintenance burden.

[0013] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0014] like Figure 1 and Figure 2 As shown, the anti-entanglement device of the transmission shaft of the conveyor belt 2 of the cocoon peeling machine is installed on a frame 1 provided with the cocoon peeling device, and the cocoon peeling device includes a conveyor belt 2 for adhering and peeling cocoon husks, and the frame 1 is provided with cocoon husk guiding and cleaning strips 3 on both sides of the conveyor belt 2, and the ends of the cocoon husk guiding and cleaning strips 3 are pressed tightly against the edges on both sides of the surface of the conveyor belt 2.

[0015] When the cocoon peeling machine is running, when the surface of the conveyor belt 2 with the peeled cocoon skins adhered to it passes through the cocoon skin guiding and cleaning strips 3, the ends of the cocoon skin guiding and cleaning strips 3 squeeze and scrape the surface of the conveyor belt 2, so that the cocoon skin residues are away from the edge of the conveyor belt 2 surface, thereby preventing them from winding around the driving shaft of the conveyor belt 2, effectively reducing the maintenance frequency and alleviating the maintenance burden.

[0016] like Figure 1 and Figure 2 As shown, the cocoon casing guiding and cleaning strip 3 is arc-shaped, the plane where the cocoon casing guiding and cleaning strip 3 is located forms an angle with the surface of the conveyor belt 2, and the extension direction of the end of the cocoon casing guiding and cleaning strip 3 forms an acute angle with the running direction of the conveyor belt 2.

[0017] Through the elasticity of the cocoon lining guide cleaning strip 3 and the angle between the strip and the surface of the conveyor belt 2, the cocoon lining guide cleaning strip 3 is always in close contact with the surface of the conveyor belt 2 during the operation of the conveyor belt 2 to clean the cocoon lining residual silk; at the same time, the cocoon lining guide cleaning strip 3 and the conveyor belt 2 are prevented from being scratched and damaged during operation due to rigid contact without buffering room. The angle between the extension direction of the contact part of the end of the cocoon lining guide cleaning strip 3 with the conveyor belt 2 and the running direction of the conveyor belt 2 is less than ninety degrees. When the conveyor belt 2 is running, the cocoon lining residual silk on both sides of the guide is gathered from the outside to the inside along the cocoon lining guide cleaning strip 3.

[0018] The end of the cocoon casing guiding and cleaning strip 3 points to the conveyor belt 2, and bends in the opposite direction after contacting the conveyor belt 2, so that a side section of the arc-shaped cocoon casing guiding and cleaning strip 3 rests on the conveyor belt 2, always maintaining a large area of ​​round and blunt contact surface, avoiding the end directly poking into the conveyor belt 2 to form point contact and cause damage.

[0019] like Figure 1 As shown, the frame 1 is provided with bolts 4 and screw holes that cooperate with each other, the head of the cocoon lining guide cleaning pressure strip 3 is provided with a mounting ring 5, and the bolt 4 passes through the mounting ring 5 and the screw hole in sequence to be connected to the frame 1. The cocoon lining guide cleaning pressure strip 3 is fixedly connected to the frame 1 by pressing the mounting ring 5 with the bolt 4.

[0020] like Figure 1 and Figure 2 As shown, the mounting ring 5 is at a certain angle to the plane where the cocoon guide cleaning layer 3 is located. By loosening the bolt 4 and rotating the mounting ring 5 with the bolt 4 as the axis, the contact surface size, contact angle and contact pressure between the cocoon guide cleaning layer 3 and the conveyor belt 2 can be changed. When the cocoon guide cleaning layer 3 is made of a metal material with strong plasticity, the mounting ring 5 can be directly formed by bending and surrounding the cocoon guide cleaning layer 3 itself.

[0021] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
