[0003] For the existing trimming of the remaining edges of rubber sleeves, the rubber sleeve to be trimmed is clamped and fixed on the workbench of the cutting equipment, and then the cutting frame is used to cut and trim the rubber sleeve. However, since the rubber sleeve is easily stuck on the cutting frame after cutting, it is not easy to discharge and collect the rubber sleeve, resulting in low efficiency in trimming the remaining edges of the rubber sleeve.

[0004] Therefore, a device for trimming the remaining edges of rubber sleeves is now developed, which can prevent the rubber sleeve after cutting from being stuck in the cutting frame, facilitate the collection of the rubber sleeve, and improve the efficiency of trimming the remaining edges of the rubber sleeve. Content of the Utility Model

[0005] In order to overcome the shortcomings that in the existing trimming of the remaining edges of rubber sleeves, the rubber sleeve is easily stuck on the cutting frame after cutting, it is not easy to discharge and collect the rubber sleeve, resulting in low efficiency in trimming the remaining edges of the rubber sleeve, the utility model provides a device for trimming the remaining edges of rubber sleeves, which can prevent the rubber sleeve after cutting from being stuck in the cutting frame, facilitate the collection of the rubber sleeve, and improve the efficiency of trimming the remaining edges of the rubber sleeve.

Detailed implementation mode

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and the specific implementation mode, but the protection scope and application scope of the present invention are not limited.

[0020] A trimming device for the surplus edge of a rubber sleeve, as Figure 1 and Figure 2 shown, includes a base 1, a rotating frame 2, a limiting block 3, a first pressure spring 4, a swing rod 5, an electric push rod 6, a cutting frame 7, an auxiliary mechanism 8 and a pressing mechanism 9. A rotating frame 2 is rotatably connected to the upper side of the middle part of the base 1. Four limiting blocks 3 are slidably connected to the rotating frame 2. The limiting blocks 3 are all arc-shaped, which is convenient for limiting the rubber sleeve. A first pressure spring 4 is connected between each limiting block 3 and the rotating frame 2. A swing rod 5 is rotatably connected between each limiting block 3 and the rotating frame 2. Electric push rods 6 are connected to the upper sides of the left and right parts of the base 1 respectively. A cutting frame 7 is connected between the telescopic ends of the electric push rods 6. An auxiliary mechanism 8 is arranged on the cutting frame 7, and a pressing mechanism 9 is also arranged on the cutting frame 7.

[0021] As Figure 1 and Figure 3 shown, the auxiliary mechanism 8 includes a fixed block 81, a sliding frame 82, a second pressure spring 83, a telescopic assembly 84 and a pressing block 85. Four fixed blocks 81 are connected to the cutting frame 7. Sliding frames 82 are slidably connected to the fixed blocks 81 respectively. Two second pressure springs 83 are connected between each sliding frame 82 and the adjacent fixed block 81. Telescopic assemblies 84 are connected to the lower parts of the sliding frames 82 respectively. Pressing blocks 85 are connected to the telescopic assemblies 84 respectively. The telescopic assembly 84 includes a telescopic rod and a telescopic spring. Two telescopic rods are slidably connected to each sliding frame 82 respectively. A telescopic spring is connected between each telescopic rod and the connected sliding frame 82. A pressing block 85 is connected between the adjacent telescopic rods.

[0022] When using the present utility model, first place the base 1 in the trimming area of the rubber sleeve's remaining edge, then rotate the rotating frame 2, causing the swing rod 5 to rotate, making the limit block 3 slide away from each other to open. The first compression spring 4 is compressed and contracted. Then place the rubber sleeve to be trimmed between the rotating frames 2 on the base 1, and then rotate the rotating frame 2 to reset, causing the swing rod 5 to rotate. The first compression spring 4 rebounds, causing the limit block 3 to slide on the rotating frame 2 and approach each other to clamp and limit the rubber sleeve. Then start the electric push rod 6, and make the telescopic end of the electric push rod 6 push downward, causing the cutting frame 7 to move downward to cut the remaining edge of the rubber sleeve. When the cutting frame 7 moves downward, the pressing block 85 moves downward to contact the rubber sleeve, causing the sliding frame 82 to slide upward. The second compression spring 83 is compressed and contracted, causing the pressing block 85 to press the remaining edge of the rubber sleeve. Then the cutting frame 7 contacts the rubber sleeve again to cut the remaining edge of the rubber sleeve. When the cutting frame 7 cuts to the bottom of the rubber sleeve, the cutting frame 7 squeezes the limit block 3 to move outward away from the rubber sleeve. At the same time, the cutting frame 7 squeezes the pressing block 85 to move outward. The telescopic rod in the telescopic assembly 84 slides outward, and the telescopic spring is compressed and contracted, causing the pressing block 85 to move away from the rubber sleeve, enabling the cutting frame 7 to completely cut the remaining edge of the rubber sleeve. Thus, when cutting the remaining edge of the rubber sleeve, the rubber sleeve can be pressed, facilitating the cutting by the cutting frame 7. The pressing mechanism 9 can eject and collect the cut rubber sleeve.

[0023] As Figure 1 and Figure 4 shown, it further includes a pressing mechanism 9. The pressing mechanism 9 includes a connecting rod 91, a top block 92, and a third compression spring 93. There are two left and right connecting rods 91 slidably connected to the cutting frame 7. A top block 92 is connected between the connecting rods 91. Third compression springs 93 are connected between the connecting rods 91 and the cutting frame 7 respectively. The diameter of the top block 92 is slightly smaller than the diameter of the rubber sleeve to be cut.

[0024] Using the pressing mechanism 9 of this device can eject the cut rubber sleeve. When the cutting frame 7 moves downward to cut the remaining edge of the rubber sleeve, the top block 92 moves downward to contact the rubber sleeve. The rubber sleeve squeezes the top block 92 to move upward, causing the connecting rod 91 to move upward. The third compression spring 93 is compressed and contracted. After the trimming of the remaining edge of the rubber sleeve is completed, start the electric push rod 6, causing the cutting frame 7 to move upward. The third compression spring 93 rebounds, causing the connecting rod 91 to move downward, causing the top block 92 to move downward to eject the rubber sleeve stuck in the cutting frame 7. Thus, it can prevent the cut rubber sleeve from getting stuck in the cutting frame 7, facilitating the collection of the rubber sleeve and improving the trimming efficiency of the remaining edge of the rubber sleeve.

[0025] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art.
