[0017] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings in conjunction with the embodiments. DETAILED DESCRIPTION

[0018] The invention provides a tower-mounted vacuum high-speed tape wrapping machine.

[0019] Reference Figure 1-2 , Figure 1 FIG. 1 is a schematic diagram of an overall cross-sectional structure of an embodiment of the present invention. Figure 2 FIG. 1 is a control principle diagram of an embodiment of the present invention.

[0020] like Figure 1-2 As shown, in an embodiment of the present invention, the tower-mounted vacuum high-speed tape wrapping machine includes: a machine body 100, on which a vacuum chamber 200 is rotatably provided, in which a tower-mounted wrapping tape roll 300 coaxially therewith is rotatably provided, and a cable 400 to be wrapped coaxially passes through the vacuum chamber 200 and the tower-mounted wrapping tape roll 300.

[0021] Specifically, in this embodiment, the vacuum chamber 200 includes: a left chamber 210 and a right chamber 220 that are butted and sealed against each other. When the wrapping machine is working, the left chamber 210 and the right chamber 220 are sealed and connected together. When loading and unloading, the external driving mechanism drives the right chamber 220 to separate the left chamber 210 and the right chamber 220 to facilitate loading and unloading.

[0022] A first sleeve 211 coaxial with the left cavity 210 is connected to the outer wall thereof, and a third sleeve 310 coaxial with the left cavity 210 is connected to one side wall of the tower-mounted wrapping tape reel 300. The third sleeve 310 penetrates the first sleeve 211, and the first sleeve 211 is rotatably disposed on the third sleeve 310 via a third bearing 311a, and the cable 400 to be wrapped coaxially penetrates the third sleeve 310. A bearing seat 110 is provided on the machine body 100, and the first sleeve 211 is rotatably disposed in the bearing seat 110 via a first bearing 211a.

[0023] The outer wall of the right cavity 220 is provided with a coaxial end cap 221, and the body 100 is provided with a second sleeve 120. The second sleeve 120 passes through the end cap 221, and the cable 400 to be wrapped coaxially passes through the second sleeve 120, and the end cap 221 is rotatably arranged on the second sleeve 120 through the second bearing 221a.

[0024] In this embodiment, both the first bearing 211 a and the second bearing 221 a are high-speed precision bearings to adapt to the high-speed rotation of the vacuum chamber 200 during operation.

[0025] A deflection correction guide wheel 230 is provided on the inner wall of the vacuum chamber 200 . The other end of the wrapping tape 320 on the tower-mounted wrapping tape reel 300 is wound around the cable 400 to be wrapped, and the deflection correction guide wheel 230 presses the wrapping tape 320 tightly.

[0026] The wrapping machine further includes: a first driver 130, a second driver 410, a vacuum pump 140 and a controller 150. The first driver 130 is used to drive the vacuum chamber 200 to rotate, the second driver 410 is used to drive the cable 400 to be wrapped to move axially, the vacuum pump 140 is connected to the inside of the vacuum chamber 200 through a vacuum pipe 141, and is used to vacuum the inside of the vacuum chamber 200, and the controller 150 is used to control the first driver 130, the second driver 410, and the vacuum pump 140 to work. In this embodiment, the controller 150 is a PLC controller.

[0027] Specifically, in this embodiment, a tension sensor 231 is provided on the deviation correction guide wheel 230, and a magnetic powder brake 160 is also provided on the machine body 100. The tension sensor 231 and the magnetic powder brake 160 are both connected to the controller 150 by signal, and the magnetic powder brake 160 is connected to the third sleeve 310 by transmission. The tension sensor 231 monitors the tension of the wrapping tape 320 in real time, and feeds back the monitored tension signal to the controller 150. The controller 150 receives the monitored tension signal and compares it with the tension preset by the controller 150. If there is a deviation, a control signal is sent to the magnetic powder brake 160, so as to control the magnetic powder brake 160 to brake to adjust the rotation force of the tower-mounted wrapping tape roll 300, thereby controlling the tension of the wrapping tape 320, and realizing real-time adjustment of the tension of the wrapping tape 320.

[0028] Since the vacuum chamber 200 is evacuated, when the wrapping tape 320 wraps the cable 400 to be wrapped in the vacuum chamber 200, the tension of the wrapping tape 320 eliminates the influence of air resistance, and the tension of the wrapping tape 320 almost entirely comes from the braking force of the magnetic powder brake 160. Therefore, in this embodiment, the tension of the wrapping tape 320 adjusted by controlling the braking force of the magnetic powder brake 160 is constant and precise, which can ensure the consistent roundness of the cable after wrapping.

[0029] The wrapping machine adopts a high-speed rotating vacuum chamber 200. The wrapping belt in the vacuum chamber 200 greatly reduces the air resistance during operation, so that the wrapping speed can reach up to 5000 rpm, which is 3 times higher than that of traditional open wrapping machines.

[0030] The wrapping process of the wrapping machine is carried out in a vacuum chamber 200. Since the wrapping process is not affected by air resistance, the operating noise ratio can be lower than 40 decibels, which greatly reduces noise compared to traditional open wrapping machines.

[0031] Specifically, in this embodiment, a first transmission wheel 211b is provided on the first sleeve 211, and the first driver 130 is connected to the first transmission wheel 211b through a first synchronous belt 211c. When the wrapping machine is working, the first driver 130 drives the first sleeve 211 to rotate at a high speed, thereby driving the left cavity 210 and the right cavity 220 sealed and connected together to rotate at a high speed.

[0032] Specifically, in this embodiment, the third sleeve 310 is provided with a second transmission wheel 312, and the magnetic powder brake 160 is connected to the second transmission wheel 312 through a second synchronous belt 312a. When the controller 150 controls the magnetic powder brake 160 to brake, the magnetic powder brake 160 generates resistance to the rotation of the tower-mounted wrapping tape roll 300 on the third sleeve 310 through the second synchronous belt 312a, thereby increasing the tension of the wrapping tape 320 on the tower-mounted wrapping tape roll 300 during wrapping, and vice versa, reducing the tension of the wrapping tape 320 during wrapping.

[0033] Specifically, in this embodiment, in order to achieve precise control over the high-speed rotation of the vacuum chamber 200 and the axial movement speed of the cable 400 to be wrapped, both the first driver 130 and the second driver 410 use servo motors.

[0034] Specifically, in this embodiment, in order to facilitate the vacuuming process inside the vacuum chamber 200 , the second sleeve 120 is provided with a vacuum channel 121 communicating with the inside of the vacuum chamber 200 , and the vacuum pump 140 is communicated with the vacuum channel 121 through a vacuuming pipe 141 .

[0035] Specifically, in this embodiment, in order to monitor the vacuum degree inside the vacuum cavity 200 in real time and to perform vacuum treatment on the inside of the vacuum cavity 200 in real time, a pressure detector 240 is provided on the inner wall of the vacuum cavity 200, and the pressure detector 240 is connected to the controller 150 by signal. When the wrapping machine is working, if the vacuum degree value inside the vacuum cavity 200 is lower than the vacuum degree value preset by the controller 150, the controller 150 controls the vacuum pump 140 to perform vacuum treatment on the vacuum cavity 200 to ensure the vacuum environment inside the vacuum cavity 200.

[0036] In this embodiment, in order to facilitate the straightening and wrapping of the cable 400 to be wrapped, the body 100 is further provided with a first guide cylinder 170 and a second guide cylinder 180. The first guide cylinder 170 passes through the third sleeve 310 and the tower-mounted wrapping tape reel 300, and the cable 400 to be wrapped passes through the first guide cylinder 170 into the vacuum chamber 200, and passes through the second guide cylinder 180 after wrapping.

[0037] The wrapping machine adopts a tower-mounted wrapping tape reel 300 for feeding, and can supply wrapping tape raw materials with a length of not less than 10,000 meters at a time, greatly reducing the frequency of material changes.

[0038] In this embodiment, in order to extend the length of the cable 400 to be wrapped that can be processed at one time, each time the material is loaded, a spare tower-mounted wrapping tape roll 300 is also loaded on the second guide cylinder 180. If the current tower-mounted wrapping tape roll 300 is about to run out, the operator only needs to connect the spare tower-mounted wrapping tape roll 300 to the current tower-mounted wrapping tape roll 300, without taking the cable 400 to be wrapped out of the vacuum chamber 200 before loading and unloading, thereby saving downtime and further improving production efficiency.

[0039] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
