DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] See also Figure 1-5 The present invention provides a technical solution: a novel automatic doffing device for a spinning machine, comprising a doffing machine 1 and a motor box 2 slidably arranged thereon, the motor box 2 having a crank contact port 21 and a lifting motor 22 connected to the crank contact port 21 arranged inside, a lifting device 4 connected to the lifting motor 22 is installed on the upper surface of the motor box 2, a photoelectric proximity switch 3 is arranged on one side of the upper surface of the motor box 2 close to the crank contact port 21, and the photoelectric proximity switch 3 is connected to the lifting motor 22;

[0025] A steel collar plate 5 is arranged on the top of the lifting device 4, a support frame 6 is fixedly connected to the steel collar plate 5, and a clamping assembly 7 for clamping the spun yarn tube 10 is arranged on the support frame 6;

[0026] A buzzer 9 connected to the photoelectric proximity switch 3 is provided at the end of the doffing vehicle 1 .

[0027] In this embodiment, the lifting motor 22 is started when the yarn doffing car 1 starts, and the lifting motor 22 provides power to the lifting device 4 and enables the lifting device 4 to start working, so that the lifting device 4 drives the steel collar plate 5 to rise to the starting spinning position, and then the main machine starts. At this stage, the operator uses the crank handle to shake the lifting motor 22 to raise the steel collar plate 5 in order to reduce the end breakage rate. If the operator works for a long time and sometimes loses concentration, he may mistakenly insert the crank handle into the crank handle contact port 21 before the lifting motor 22 starts. At this time, the crank handle enters the working range of the photoelectric proximity switch 3, and the photoelectric proximity switch 3 forcibly stops the lifting motor 22 from rotating. At the same time, the photoelectric proximity switch 3 controls the buzzer 9 to sound an alarm, thereby avoiding the problem of safety accidents caused by the crank handle rotating at high speed with the lifting motor 22 and causing injuries, and can also remind the staff.

[0028] Furthermore, a first slide groove 11 is provided on the upper surface of the yarn doffing vehicle 1, and second slide grooves 12 connected to the first slide groove 11 are respectively provided on the front and rear surfaces of the yarn doffing vehicle 1, and a first slider 23 slidably matched with the first slide groove 11 is provided on the lower surface of the motor box 2, and a second slider 24 slidably matched with the second slide groove 12 is provided on the front and rear surfaces of the first slider 23.

[0029] In this embodiment, when the horizontal position of the spun yarn tube 10 needs to be adjusted, the motor box 2 can be moved, and the motor box 2 performs horizontal linear motion on the upper surface of the doffing vehicle 1. Preferably, at least one of the first slider 23 and the second slider 24 is a slider provided with damping.

[0030] Furthermore, the support frame 6 includes a first vertical plate 61 fixedly connected to the upper surface of the collar plate 5 , a horizontal plate 62 integrally provided at the top of the first vertical plate 61 , and a second vertical plate 63 integrally provided at an end of the horizontal plate 62 away from the first vertical plate 61 .

[0031] In this embodiment, the first vertical plate 61 , the horizontal plate 62 and the second vertical plate 63 are integrally arranged to form an inverted concave-shaped support frame 6 , and a part of the clamping assembly 7 is arranged in the concave portion of the support frame 6 .

[0032] Furthermore, the clamping assembly 7 includes a rotating motor 71 installed on the first vertical plate 61, the output end of the rotating motor 71 passes through the first vertical plate 61, a bidirectional screw 72 is rotatably connected between the first vertical plate 61 and the second vertical plate 63, the bidirectional screw 72 is fixedly connected to the output end of the rotating motor 71, and a sliding rod 73 is fixedly connected between the first vertical plate 61 and the second vertical plate 63 and respectively located on both sides of the bidirectional screw 72, and two clamping plates 74 arranged opposite to each other are passed through the bidirectional screw 73, and each clamping plate 74 slides through the sliding rod 73.

[0033] In this embodiment, the bidirectional screw 72 has two equal-length and opposite-direction threads. When the spun yarn tube 10 is to be clamped, the output end of the rotating motor 71 rotates, driving the bidirectional screw 72 to rotate. The bidirectional screw 72 drives the two clamping plates 74 to move toward or away from each other. When the two clamping plates 74 move toward each other, the movement is stopped until the two clamping plates 74 clamp the spun yarn tube 10.

[0034] Furthermore, the opposite surfaces of the two clamping plates 74 are each provided with a clamping groove 75 , and the clamping groove 75 is filled with foam material.

[0035] In this embodiment, the foam material can increase the friction between the clamping plate 74 and the spun yarn tube 10 to prevent the spun yarn tube 10 from falling.

[0036] Furthermore, rubber pads are sleeved or embedded on the opposite surfaces of the two clamping plates 74 .

[0037] In this embodiment, the rubber pad can protect the spun yarn tube 10 from being damaged by the clamping plate 74.

[0038] Furthermore, a reinforcing device 8 is included. The reinforcing device 8 includes reinforcing studs 81 respectively arranged on the first vertical plate 61 and the collar plate 5 , and the two reinforcing studs 81 are connected by a connecting rod 82 .

[0039] In this embodiment, the connecting rod 82 fixes the two reinforcing studs 81 , thereby increasing the supporting stability of the first vertical plate 61 .

[0040] Furthermore, both ends of the connecting rod 82 have holes for the reinforcing studs 81 to pass through. When the connecting rod 82 is connected between two reinforcing studs 81 , the free end of each reinforcing stud 81 is also threadedly connected with a reinforcing nut 83 .

[0041] In this embodiment, the holes on the connecting rod 82 are correspondingly inserted into the reinforcing stud 81, and then screwed into the reinforcing nut 83 for locking.

[0042] Furthermore, the lifting device 4 is an electric push rod.

[0043] In this embodiment, the electric push rod is a product that is relatively easy to obtain on the market and has low cost.

[0044] The working principle and use process of the present invention are as follows: After the present invention is installed, the lifting motor 22 is started when the yarn dropping car 1 starts, and the lifting motor 22 provides power to the lifting device 4 and enables the lifting device 4 to start working, so that the lifting device 4 drives the steel collar plate 5 to rise to the starting spinning position, and then the main machine starts. At this stage, the operator uses the crank handle to shake the lifting motor 22 to raise the steel collar plate 5 in order to reduce the end breakage rate. If the operator works for a long time and sometimes loses concentration, he may mistakenly insert the crank handle into the crank handle contact port 21 before the lifting motor 22 starts. At this time, the crank handle enters the working range of the photoelectric proximity switch 3, and the photoelectric proximity switch 3 forcibly prevents the lifting motor 22 from rotating. At the same time, the photoelectric proximity switch 3 controls the buzzer 9 to emit an alarm sound, thereby avoiding the problem of safety accidents caused by the crank handle rotating at high speed with the lifting motor 22 and causing injuries, and can also remind the staff.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
