Description

Technical Field

[0001] The utility model relates to a wire lifting device, in particular to a device which can timely stop and separate wire rolls such as spandex wire from operation by wire lifting, and belongs to the technical field of textile machinery. Background Art

[0002] At present, in the spinning process, when the spinning breaks, it is necessary to detect and deal with it in time. For example, when processing core-spun yarn, since the processed core-spun yarn is prone to breakage during the winding process, when the wire breaks, it is necessary to stop the operation in time to prevent the core-spun yarn from failing to be wound and causing waste of materials. For this reason, Chinese patent CN202023333878.7 discloses "a core wire monitoring device applied to a ring spinning machine", which can use a rod body rotatably connected to the mounting part so that the rod body can collide with the core-spun yarn under the drive of the adapter. If the core-spun yarn breaks, the rod body can flip so that the patrolling staff can quickly find and deal with it, which greatly reduces the risk of project delays, reduces waste, and reduces the labor intensity of the staff; at the same time, the baffle arranged on the side wall of the mounting part can prevent the rod body from flipping excessively, resulting in a break that is not easy to be discovered by the staff.

[0003] However, the last device only served as a reminder. When the patrol staff did not patrol in time, the machine could not be shut down in time. Therefore, this patent invented a wire lifting device. When the wire breaks, the spandex wire roll is lifted by the wire lifting device, thereby achieving automatic emergency shutdown. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a wire lifting device, which can smoothly lift the spandex wire roll and the like off the transmission roller through the rising wire lifting bracket, thereby achieving the effect of rapid shutdown.

[0005] The purpose of the utility model is achieved in this way:

[0006] A wire lifting device comprises a shell, a power mechanism arranged in the shell drives a lifting bar to do lifting movement, and a wire lifting bracket is connected to one end of the lifting bar outside the shell, and a limit block is connected to one end of the lifting bar inside the shell.

[0007] Preferably, a lower limit micro switch and an upper limit micro switch are provided in the shell, and the lower limit micro switch and the upper limit micro switch are located at the lower part and the upper part of the shell, and are in contact with the limit block.

[0008] Preferably, the lifting bar is a wire lifting rack in the form of a rack, the power mechanism is a transmission motor, and a driving gear is mounted on the output shaft of the transmission motor, and the driving gear is meshed with the wire lifting rack.

[0009] Preferably, a guide slot is vertically arranged on the inner wall of the shell, and a guide bar slidably arranged in the guide slot is vertically arranged on the side wall of the wire lifting rack.

[0010] Preferably, a control box is inserted on the outer wall of the shell, a control circuit board is installed in the control box, and the broken wire detector is inserted on the control box.

[0011] Preferably, the wire lifting bracket is located between two transmission rollers, a spandex wire roll is driven between the two transmission rollers, and the wire lifting bracket is located below the transmission rollers.

[0012] Preferably, the top of the wire lifting bracket is an arc-shaped structure with an opening facing upward.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] After the utility model is used in conjunction with a broken wire detector (such as a single-spindle detector commonly sold on the market), when the broken wire detector detects that the spinning is broken, the transmission motor drives the wire lifting rack to rise and lift the spandex wire roll. At this time, the spandex wire is not continued to be fed and then automatically broken, thereby achieving the effect of automatic cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 This is a schematic diagram of the application status of a wire lifting device of the utility model.

[0017] in:

[0018] Housing 1, wire lifting rack 2, wire lifting bracket 3, driving gear 4, transmission motor 5, limit block 6, lower limit micro switch 7, upper limit micro switch 8;

[0019] Guide strip 2.1;

[0020] Control box 11, control circuit board 12, broken wire detector 13;

[0021] Transmission roller 21 and spandex yarn roll 22. DETAILED DESCRIPTION

[0022] See also Figure 1The utility model relates to a wire lifting device, in which a wire lifting rack 2 is vertically movably inserted in a shell body 1, and a wire lifting bracket 3 is connected to the end of the wire lifting rack 2 located outside the shell body 1, and the top of the wire lifting bracket 3 is an arc structure with an opening upward, so as to facilitate lifting the spandex wire roll 22, and the end of the wire lifting rack 2 located in the shell body 1 is connected to a limiting block 6, and in order to ensure the stability of the wire lifting rack 2 when it is lifted up and down, a guide groove is vertically arranged on the inner wall of the shell body 1, and a guide bar 2.1 in the guide groove is vertically arranged on the side wall of the wire lifting rack 2, so that the wire lifting rack 2 can be smoother and more stable during the up and down lifting process.

[0023] At the same time, the lifting power of the wire lifting rack 2 is provided by the transmission motor 5 installed in the housing 1. The output shaft of the transmission motor 5 is provided with a driving gear 4, which is engaged with the teeth on the wire lifting rack 2, thereby driving the wire lifting rack 2 to move up and down through the driving gear 4. In the process of the wire lifting rack 2 moving up and down, the role of the limit block 6 is to cooperate with the lower limit micro switch 7 and the upper limit micro switch 8 to achieve its rising and falling limit operation. Therefore, the lower limit micro switch 7 and the upper limit micro switch 8 are respectively installed at the upper and lower parts of the housing 1, and contact with the limit block 6 to achieve the rising and falling limit operation.

[0024] When in use, the wire lifting device also needs to cooperate with the broken wire detector 13 to realize broken wire detection. At this time, the broken wire detector 13 is installed in the control box 11, and a control circuit board 12 is arranged in the control box 11. The control circuit board 12 receives the signal of the broken wire detector 13, and the control circuit board 12 controls the transmission motor 5 of the wire lifting device.

[0025] See also Figure 2 When in use, the wire lifting device is installed between two transmission rollers 21 and is located below the spandex wire roll 22 between the two transmission rollers 21.

[0026] When the broken wire detector 13 detects that the spinning is broken, the transmission motor 5 drives the wire lifting rack 2 to rise and lift the spandex wire roll 22. At this time, the spandex wire will no longer be fed and will automatically break, achieving the effect of automatic cutting and stopping.

[0027] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
