DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 10The present invention provides a technical solution: an insulating sleeve opening device, comprising a support frame 1, a motor 2, and a mounting plate group 3, wherein the motor 2 is mounted in the support frame 1, the mounting plate group 3 is fixedly mounted on the top of the support frame 1, a rotating shaft 4 is arranged on the mounting plate group 3, a cam 5 is arranged at the end of the rotating shaft 4, and symmetrical opening structures 6 are arranged on both sides of the cam 5, and the cam 5 can drive the opening structures 6 on both sides to help the insulating sleeves 100 on both sides to complete the opening; The opening structure 6 includes a movable shaft 61 and an opening tool 62. The movable shaft 61 can be driven by the cam 5 to move laterally. The opening tool 62 is installed on the movable shaft 61 and can move with the movable shaft 61. Limiting frames 7 are provided on both sides of the opening tool 62. The opening tool 62 is driven by the movable shaft 61 to squeeze the opening of the insulating sleeve 100 from the outside of the insulating sleeve 100 and enter the insulating sleeve 100 to open the opening; The limiting frame 7 is installed on the mounting plate group 3, and a placing frame 8 is provided above the limiting frame 7. The placing frame 8 is used to place the insulating sleeve 100 and ensure that the insulating sleeve will not deviate in the vertical direction; The placement rack 8 is installed on the mounting plate group 3 , and the placement rack 8 is used to place the insulating sleeve 100 .

[0020] In this embodiment, the motor 2 is connected to the rotating shaft 4 via a pulley set, and the motor 2 drives the rotating shaft 4 to rotate, thereby driving the cam 5 to rotate.

[0021] In this embodiment, the mounting plate group 3 includes a front plate 31, a rear plate 32 and a connecting plate 33. The front plate 31 and the rear plate 32 are arranged side by side and in parallel. The connecting plate 33 is installed between the front plate 31 and the rear plate 32. The connecting plate 33 has a connecting function and also a supporting function.

[0022] In this embodiment, the cam 5 includes a protruding portion 51 and a recessed portion 52. The protruding portion 51 is symmetrically arranged on both sides of the recessed portion 52 and the edge is higher than the recessed portion 52. A paddle structure 53 is provided on the cam part of the cam 5. The protruding portion 51 can contact with the movable shaft 61 to reduce the contact area.

[0023] In this embodiment, the paddle structure 53 includes a mounting seat 531, a paddle 532 and a fixing screw 533. The mounting seat 531 is installed in a corresponding groove on the cam 5, and the paddle 532 is fixedly installed in the mounting seat 531. The side of the mounting seat 531 is locked in the cam 5 by the fixing screw 533. The paddle 532 driven by the rotation of the cam 5 can intermittently paddle the rocker 614.

[0024] In this embodiment, the movable shaft 61 is installed in the guide block 1 63 and the guide block 2 64 arranged side by side. The movable shaft 61 is provided with a spring 65. The spring 64 is arranged between the guide block 1 63 and the retaining ring 66. The retaining ring 66 is fixedly installed on the movable shaft 61. The end of the movable shaft 61 is provided with a friction surface 611 and a toggle pin 612. The position of the friction surface 611 corresponds to the protrusion 51. The toggle pin 612 can contact with the paddle 532. The guide block 2 64 is provided with a guide slope 641. The guide slope 641 contacts the lower end opening of the insulating sleeve 100. The spring 65 is used to help the movable shaft 61 to reset. The friction surface 611 provides a surface in contact with the protrusion 51, and lubricating oil is applied thereon to make the operation smoother.

[0025] In this embodiment, an elastic pad 613 is provided under the toggle pin 612, and a rocker arm 614 is fixedly connected to the toggle pin 612. A support shaft 615 is provided on the rocker arm 614, and the support shaft 615 is installed on the movable shaft 61. The other end of the rocker arm 614 is connected to the bottom of the opening tool 62. When the paddle 532 toggles the toggle pin 612, the rocker arm 614 will swing around the support shaft 615, thereby realizing the swing of the rocker arm 614.

[0026] In this embodiment, a sliding shaft 621 is provided at the bottom of the opening tool 62, and the sliding shaft 621 is connected to the movable shaft 61 by sliding up and down. A sliding pin 622 is provided on the sliding shaft 621, and the sliding pin 622 is connected to the rocker arm 614. When the rocker arm 614 swings, it will cause the opening tool 62 to vibrate up and down. Because the tool is in the insulating sleeve 100, it will drive the insulating sleeve 100 to vibrate up and down, so that the glue applied to the opening of the insulating sleeve 100 from the top flows downward under the action of vibration, and fills the glue groove on the insulating sleeve 100, so as to help to seal the insulating sleeve 100 with glue later.

[0027] In this embodiment, the limit frame 7 is connected to the sliding rail 72 through the connecting frame 71. The limit frame 7 is provided with a blade protection groove. The sliding rail 72 is installed on the support frame 1. The sliding rail 72 facilitates the adjustment of the position of the limit frame 7. The second limit frame 7 is used to limit the position of the opening tool 62.

[0028] In this embodiment, the placement rack 8 includes a limiting side plate 1 81 and a limiting side plate 2 82. The limiting side plate 1 81 is higher than the insulating sleeve 100. The placement rack 8 is fixedly installed on the support frame 1 through a base 83. The limiting side plate 1 81 and the limiting side plate 2 82 clamp the insulating sleeve to prevent it from swinging left and right and affecting the opening.

[0029] Working principle: install the insulating sleeve 100 in the placement rack 8, and then start the motor 2 to drive the cam 5 to rotate. The cam part of the cam 5 squeezes the movable shaft 61, so that the movable shaft 61 brings the opening tool 62 to force open the opening of the insulating sleeve 100, and the higher limiting side plate 81 can provide better supporting force. Glue is dripped on the top of the opening of the opened insulating sleeve 100. When the paddle 532 moves the paddle pin 612, the opening tool 62 vibrates the insulating sleeve 100 in the vertical direction, so that the glue flows under the action of gravity and inertia and covers the entire opening. Subsequently, the opening tool 62 is moved out of the insulating sleeve and passed through the cable, etc., thereby completing the opening, threading, and gluing and sealing of the insulating sleeve.

[0030] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
