Description

Technical Field

[0001] This utility model relates to a fabric inlet / outlet device for a dyeing machine. Background Technology

[0002] Chinese patent application publication number CN110453423A, entitled "An Automated Fabric Input / Output System for a Dyeing Machine," discloses a system for improving the liquid dyeing production process of a dyeing machine. The system uses a fabric fastener to connect the fabric head and tail. During operation, the fabric passes through a reverse-fastener gripper on a screw-nut nozzle, which is then locked onto a metal tube. When the fabric is pulled out of the fastener, the reverse-fastener grips it tightly, preventing it from slipping out. However, the fastener relies primarily on the reverse-fastener gripper to connect the fabric, which presents problems such as loose connections and the gripper tearing the fabric, leading to breakage. Therefore, the existing system needs further improvement. Summary of the Invention

[0003] This invention addresses the problems arising from existing technologies by providing a fabric inlet / outlet device for a dyeing machine, which can improve the tightness of the connected fabric and prevent fabric breakage.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fabric feeding and feeding device for a dyeing machine includes a feeder and several fabric fasteners. The feeder is a piece of fabric used to guide greige fabric into the dyeing machine for dyeing. The fabric fasteners include open and female fasteners that can be interlocked. The head and tail of the feeder are connected to the open fasteners, and the head and tail of the greige fabric are connected to the female fasteners. The open fastener includes a male connector, a male fastener gripper, and a male locking ring. The female fastener includes a female connector, a female fastener gripper, a female locking ring, and a locking device. Both the male and female connectors are tubular and each has a ring section with external threads, a mating section on both sides of the ring section, and a locking section. The male and female locking parts are annular, and each has several through grooves on its peripheral wall to form several locking claws that can deform radially. The locking claws are inserted into the locking section of the corresponding male or female connector. Both the male and female locking rings are provided with internal threads that are screwed into the external threads of the corresponding male or female connector to fix the male or female locking parts in the axial direction and at the same time make the locking claws of the male or female locking parts deform radially inward. After the male connector and the female connector are connected to each other, the locking device fixes and locks the male and female connectors in the axial direction.

[0006] The advantages of this invention are as follows: when in use, the beginning and end of the fabric and the greige fabric pass through the male or female locking ring and are then locked together by the male or female fastener, which not only improves the tightness of the connected fabrics but also avoids problems such as fabric breakage.

[0012] A fabric inlet / outlet device for a dyeing machine includes a guide fabric and several fabric fasteners. The guide fabric is a piece of fabric used to guide the greige fabric into the dyeing machine for dyeing. The fabric fasteners include an open fastener 1 and a female fastener 5 that can be interlocked together. The open fastener 1 is connected to the head and tail of the guide fabric, and the female fastener 5 is connected to the head and tail of the greige fabric. The fabric inlet / outlet device for a dyeing machine is described in the specification of Chinese patent application publication number CN110453423A, entitled "An Automated Fabric Inlet / Outlet System for a Dyeing Machine." This specification will not elaborate on the specific working process, but will only specifically describe the fabric fasteners.

[0013] As attached Figure 1 To be continued Figure 5 As shown, the buckle 1 includes a male connector 11, a male buckle gripper 12, and a male locking ring 13, while the female buckle 5 includes a female connector 51, a female buckle gripper 52, a female locking ring 53, and a locking device.

[0014] Both the male connector 11 and the female connector 51 are tubular bodies, and both have an annular section 21 with external threads, a mating section 22 and a locking section 23 located on both sides of the annular section 21.

[0015] The male latch 12 and the female latch 52 are annular, and each of them has several through grooves 31 on its peripheral wall to form several latch claws 32 that can be radially elastically deformed. The latch claws 32 are inserted into the locking section 23 of the corresponding male connector 11 or female connector 51.

[0016] Both the male locking ring 13 and the female locking ring 53 are provided with internal threads that are screwed into the external threads of the corresponding male connector 11 or female connector 51 to fix the male latching member 12 or female latching member 52 axially to the male connector 11 or female connector 51, while causing the latching claw 32 of the male latching member 12 or female latching member 52 to deform radially inward; the outer peripheral walls of both the male locking ring 13 and the female locking ring 53 are provided with several anti-slip protrusions.

[0017] After the male connector 11 and the female connector 51 are connected to the docking section 22, the locking device fixes the male connector 11 and the female connector 51 in the axial direction.

[0018] The locking device includes a locking sleeve 61, a spring 62, and several ball bearings 63; a groove 24 is provided circumferentially on the outer side wall of the mating section 22 of the male connector 11. The side wall of the mating section 22 of the female connector 51 has a flange 71, a threaded hole 72, and several through holes 73 spaced apart along the same circumference. A guide post 74 is threadedly connected to the threaded hole 72, and each through hole 73 is equipped with the ball bearing 63; the inner wall of the locking sleeve 61 has an abutment platform 66 and a drop platform 67 connected by an inclined surface 65. An abutment surface is formed on the side of the abutment platform 66 facing away from the inclined surface 65; the locking sleeve 61 is fitted onto the mating section 22 of the female connector 51, and the guide post 74 falls in the sliding groove 64, so that the locking sleeve 61 is circumferentially limited and can only slide and switch between a locked position and an unlocked position axially.

[0019] One end of the spring 62 abuts against the flange 71 and the other end abuts against the abutting surface. The abutting platform 66 causes the ball 63 to fall into the slot 24 of the male connector 11. In this state, the locking sleeve 61 is in the locked position, and the male connector 11 and the female connector 51 are connected together. When the locking sleeve 61 slides axially to switch to the unlocked position, the locking sleeve 61 overcomes the action of the spring 62, and the ball 63 is placed on the falling platform 67 via the inclined surface 65 and disengages from the slot 24 of the male connector 11. The male connector 11 and the female connector 51 can then be separated from each other.

[0020] There is only one spring 62, which is sleeved on the docking section 22 of the female connector 51, as shown in the attached drawings.

[0021] Because the fabric is connected to the beginning and end of the fabric and is quite heavy after dyeing, in order to avoid the failure of the ball 63 to fall into the slot 24 of the male connector 11 due to insufficient force of the spring 62, resulting in a failed connection, the spring 62 can also be a number of springs, evenly spaced with the axis of the female connector 51 as the central axis.

[0022] In use, the beginning and end of the lead fabric and the greige fabric pass through the male locking ring 13 or the female locking ring 53 and are then locked together by the male fastener 12 or the female fastener 52. This not only improves the tightness of the connected fabrics but also avoids problems such as fabric breakage.

[0023] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
