Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0028] Reference Figures 1 to 3 The utility model provides a belt-type cable tail pressing device, comprising a base unit 1, a mobile unit 2, a bracket unit 3 and a Y-shaped belt unit 4. The mobile unit 2 is connected to the base unit 1, and the base unit 1 serves as a fixed support for other units. The mobile unit 2 is connected to the bracket unit 3. The Y-shaped belt unit 4 is connected to the front end of the bracket unit 3. The Y-shaped belt unit 4 is provided with a belt 41 capable of pressing the cable tail.

[0029] The moving unit 2 can drive the bracket unit 3 to move in the front and rear directions, and the bracket unit 3 can drive the Y-belt unit 4 to move synchronously. After the Y-belt unit 4 moves into position toward the cable tail, the cable tail can be compressed by the belt 41. Since the belt 41 itself has a certain coverage range in both the length and width directions, it has a larger contact area when in contact with the cable tail than the traditional tail-pressing wheel. The cable tail can be firmly surrounded by the expanded contact surface, maintaining the stability of the cable tail trajectory, avoiding the cable tail from falling, and reducing the probability of failure. At the same time, by adjusting the position of the Y-belt unit 4, the device can cope with cables of different specifications and meet diverse product requirements.

[0030] As an optional embodiment, the base unit 1 includes a base fixing plate 11 and support legs 12, and several support legs 12 are connected to the bottom of the base fixing plate 11.

[0031] As an optional embodiment, the moving unit 2 includes a moving base plate 21, a tail-pressing cylinder 22, a guide rail 23 and a slider 24;

[0032] The movable bottom plate 21 and the base fixing plate 11 are detachably connected and their relative positions in the front-to-back direction can be adjusted to cope with cables of different specifications and to perform flexible adjustments when necessary. Preferably, elongated adjustment holes are provided on the movable bottom plate 21 and the base fixing plate 11, and after being moved into position, they are fastened by bolts to form a fixed position.

[0033] The cylinder seat of the tail-pressing cylinder 22 is connected to the top of the movable base plate 21 through a fixed frame, and the piston rod of the tail-pressing cylinder 22 is connected to the bracket unit 3. The tail-pressing cylinder 22 is the key actuator of the cable pressing action;

[0034] The guide rail 23 is connected to the top of the movable base plate 21 , and the guide rail 23 is parallel to the moving direction of the bracket unit 3 and the Y-belt unit 4 . The slider 24 is connected to the bottom of the bracket unit 3 and is slidably connected to the guide rail 23 .

[0035] When the bracket unit 3 and the Y-belt unit 4 need to be moved, the tail cylinder 22 can be started to drive the bracket unit 3 to move relative to the guide rail 23 with the assistance of the slider 24, so that the bracket unit 3 and the Y-belt unit 4 can be moved conveniently and quickly.

[0036] As an optional embodiment, the bracket unit 3 includes a bracket moving base plate 31, a vertical plate 32 and a buffer unit 33. The bracket moving base plate 31 is respectively connected to the piston rod of the tail pressure cylinder 22 and the slider 24.

The buffer unit 33 is connected to the upper part of the vertical plate 32 and is connected to the Y-type belt unit 4. When the Y-type belt unit 4 contacts the cable tail, the buffer unit 33 can play a buffering role to keep the Y-type belt unit 4 and the cable tail tightly pressed.

[0037] As an optional embodiment, the buffer unit 33 includes a linear bearing 331, a linear bearing rod 332, a fixed block 333, a compression spring 334 and a moving frame 335;

[0038] At least two linear bearings 331 are connected to the vertical plate 32 through their bearing seats, and the two linear bearings 331 are arranged in sequence in the vertical direction;

[0039] The two ends of the linear bearing rod 332 are connected to the linear bearing 331 and the fixed block 333 respectively. The compression spring 334 is sleeved on the linear bearing rod 332 and its two ends are respectively in contact with the bearing seat of the linear bearing 331 and the fixed block 333;

[0040] The movable frame 335 and the fixed block 333 are detachably connected. The relative positions of the movable frame 335 and the fixed block 333 can be adjusted in the vertical direction. Preferably, an elongated adjustment hole is provided on the movable frame 335 and a fixing hole is provided on the fixed block 333. After being moved into position, the movable frame 335 and the fixed block 333 are fastened by bolts to form a fixed position.

[0041] The Y-belt unit 4 is connected to the movable frame 335. The movable frame 335 can drive the Y-belt unit 4 to move synchronously when adjusting its position, thereby realizing the position adjustment of the Y-belt unit 4 in the vertical direction to flexibly cope with cables of different specifications.

[0042] When the Y-belt unit 4 compresses the cable tail, the reaction force is transmitted in sequence through the movable frame 335 and the fixed block 333, and then to the linear bearing 331, the linear bearing rod 332 and the compression spring 334. The linear bearing 331, the linear bearing rod 332 and the compression spring 334 can produce a buffering and compressing effect, and cooperate with the Y-belt unit 4 to achieve a double buffering effect. The belt 41 can squeeze and contact the cable tail well, effectively preventing the cable tail from falling out, and reducing the failure rate of the equipment.

[0043] As an optional embodiment, the Y-belt unit 4 further includes a Y-shaped base plate 42, a roller 43, a buffer cylinder 44 and a connecting member 45;

[0044] The rear end of the Y-shaped base plate 42 is connected to the movable frame 335, and the two are preferably fastened by bolts to achieve synchronous movement. The front end of the Y-shaped base plate 42 is movably connected to two rollers 43, and the two rollers 43 are symmetrically arranged.

[0045] The buffer cylinder 44 is connected to the middle of the top of the Y-shaped base plate 42. The piston rod of the buffer cylinder 44 is connected to the top of the connecting member 45. The bottom of the connecting member 45 is movably connected to the third roller 43. The third roller 43 is located behind the two rollers 43. The connecting member 45 is preferably a combination structure of a locking nut and a connecting screw.

[0046] The Y-shaped bottom plate 42 is provided with an adjustment hole 421 along the front-to-back direction at a position corresponding to the connecting member 45 , so that the connecting member 45 and the third roller 43 can move relative to each other at the adjustment hole 421 ;

[0047] The belt 41 is connected to the outside of the three rollers 43. The tightness of the belt 41 can be adjusted by changing the relative position of the third roller 43. When the belt 41 contacts the cable tail, the belt 41 can move with the assistance of the three rollers 43 with rotation function.

[0048] In this embodiment, the roller 43 preferably adopts a cam structure, wherein the middle portion is more protruding than the ends, so as to maintain a positional relationship with the belt 41 when used in conjunction with the belt 41, thereby preventing the belt 41 and the roller 43 from slipping or separating;

[0049] Before the action, the buffer cylinder 44 and the tail pressure cylinder 22 are both in the starting position. At this time, the belt 41 can be in a tensioned state with the assistance of the buffer cylinder 44. After the tail pressure cylinder 22 is executed, the Y-belt unit 4 can be pushed to the front end through the guide rail 23 and the slider 24. The belt 41 contacts and squeezes the cable, and the buffer cylinder 44 will be pulled forward, so that the belt 41 has a certain degree of loosening to offset the length loss caused by the belt 41 after surrounding the cable. When the air pressure is adjusted, it plays a good buffering role. The length direction of the adjustment hole 421 is the buffering path. The buffer cylinder 44 becomes the key component for tightening the cable tail and tensioning the belt. With the mutual cooperation of the above structures, the cable compression action can be performed on cables with different ring diameters.

[0050] As an optional embodiment, it also includes a sensing unit 5, which includes a sensor 51 and a sensing movable plate 52. The sensing movable plate 52 is connected to the top of the fixed block 333, and the sensing movable plate 52 can move synchronously with the fixed block 333. The sensor 51 is connected to the top of the vertical plate 32, and the sensor 51 can move synchronously with the vertical plate 32. When the Y-belt unit 4 compresses the cable tail, the sensing movable plate 52 will move relative to the fixed block 333 toward the sensor 51. Therefore, the sensor 51 can sense the compression operation state of the Y-belt unit 4 through the position change of the sensing movable plate 52, which is convenient for the control of the control system.

[0051] As an optional embodiment, it further includes a limiting unit 6, which includes a fixed limiting bottom plate 61 and an adjustable limiting bottom plate 62;

[0052] The fixed limiting bottom plate 61 is detachably connected to the vertical plate 32. The relative position of the fixed limiting bottom plate 61 and the vertical plate 32 can be adjusted in the vertical direction. Preferably, a long adjustment hole is provided on the fixed limiting bottom plate 61, and a fixing hole is provided on the vertical plate 32. After being moved into place, they are fastened by bolts to form a fixed position.

[0053] The adjustable limiting base plate 62 is detachably connected to the fixed limiting base plate 61.
