Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a sleeve feeding mechanism. Background Technology

[0002] Flexible plastic tubing is widely used in industries such as power and water conservancy. For example, plastic tubing can be used to transport liquid substances or as a sheathing layer for power cables. Flexible plastic tubing is cut to a fixed length according to different application scenarios. Existing tubing cutting devices mainly include mechanical cutting devices and laser cutting devices. However, regardless of the type of cutting device, the tubing needs to be continuously fed into the cutting device. Currently, the commonly used feeding device is a forward-pushing structure. This type of feeding structure is only suitable for tubing of a specific diameter. If the tubing diameter is too large or too small, the feeding mechanism may not be able to effectively clamp the tubing, leading to feeding failure. Therefore, designing a feeding mechanism suitable for tubing of different diameters is a problem that needs to be considered. Utility Model Content

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A sleeve feeding mechanism includes: a base plate, a first motor, a second motor, a first roller mounting base, a second roller mounting base, a first driving roller, a second driving roller, a first driven roller, a second driven roller, a sliding assembly, a baffle, and an elastic element;

[0006] The first driving roller and the first driven roller are rotatably mounted on the first roller mounting base, and the second driving roller and the second driven roller are rotatably mounted on the second roller mounting base.

[0007] The first driving roller cooperates with the first driven roller, and the second driving roller cooperates with the second driven roller; the sleeve is conveyed forward sequentially through the middle position between the first driven roller and the second driven roller, and then through the middle position between the first driving roller and the second driving roller; the output end of the first motor is connected to the lower end of the first driving roller, and the output end of the second motor is connected to the lower end of the second driving roller; the housing of the first motor is fixedly connected to the first roller mounting base; the baffle is fixedly connected to the housing of the first motor, one end of the spring is connected to the baffle, and the other end of the spring is connected to the housing, and the spring is normally in a compressed state; under the action of the spring, the first driving roller moves close to the first driven roller to its limit position.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes: a feed plate; the feed plate is disposed on the front side of the first driven roller and the second driven roller, and the feed plate is fixed on the base plate;

The sleeve feeding mechanism also includes a sliding assembly, a baffle, and springs. Under the action of the springs, the first driving roller moves close to the first driven roller to its limit position, achieving automatic clamping of the sleeve by the first and second driving rollers. When it is necessary to change to a sleeve of a different diameter, simply pull the baffle back to further compress the spring, increasing the distance between the first and second driving rollers and the distance between the first and second driven rollers.
