Description

Technical Field

[0001] This utility model relates to the field of textile cutting technology, specifically to an automatic headband cutting machine. Background Technology

[0002] The automatic headband cutting machine is a specialized automated device for efficiently and precisely cutting headbands such as medical headbands, sports headbands, and industrial protective headbands. By integrating advanced mechanical structures, sensor technology, servo control systems, and a human-machine interface, this equipment achieves automatic feeding, positioning, cutting, and collection of headbands, significantly improving production efficiency and reducing labor costs.

[0003] A search of existing technology reveals a "fabric cutting machine" with publication number "CN222412390U". This device can adjust the length of each segment of fabric being cut by adjusting the speed of the reciprocating stroke through the reciprocating cutting component, thus enabling precise control of the length of the cut fabric segments. However, during the cutting operation, the head straps of the batch cut fabric are prone to deviation during the conveying process due to their strip shape, and they may become entangled with adjacent head straps, affecting the conveying effect.

[0004] Based on this, the present invention designs an automatic headband cutting machine to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic headband cutting machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic headband cutting machine includes a positioning frame, a servo motor fixedly connected to one side of the positioning frame, the output shaft of the servo motor extending through the inner side of the positioning frame, and a cutting mechanism disposed inside the positioning frame, the surface of the cutting mechanism extending above the positioning frame, the output shaft of the servo motor being connected to the surface of the cutting mechanism; wherein, the cutting mechanism includes a guide conveying assembly installed inside the positioning frame, the surface of the guide conveying assembly being connected to the output shaft of the servo motor, a cutting assembly being connected to the surface of the guide conveying assembly, the surface of the cutting assembly extending above the guide conveying assembly.

[0008] Furthermore, the guiding and conveying assembly includes a connecting frame fixedly connected to the inner side of the positioning frame. A support plate is fixedly connected to the upper end of the connecting frame. A drive shaft rotatably connected to the surface of the positioning frame is provided on the side of the connecting frame near the servo motor. A push roller is fixedly connected to the surface of the drive shaft. One end of the drive shaft is fixedly connected to the output shaft of the servo motor. A rotating shaft rotatably connected to the surface of the positioning frame is provided on the side of the drive shaft away from the connecting frame. Multiple airbags are sleeved on the surface of the rotating shaft.

[0009] Furthermore, the support plate has multiple guide grooves fixedly connected to the side near the drive shaft, and multiple comb-shaped strips fixedly connected to the bottom wall of the guide grooves, with the other end of the comb-shaped strips extending to the inner bottom wall of the support plate.

[0010] Furthermore, the surface of the actuating roller is provided with multiple annular grooves, and the interior of the actuating roller is provided with multiple grooves. The grooves are distributed in a ring shape along the surface of the actuating roller, and the grooves are connected to the annular grooves.

[0011] Furthermore, a connecting bracket is fixedly connected to the surface of the rotating shaft, and the inner side of the connecting bracket is fixedly connected to the surface of the airbag.

[0012] Furthermore, the surface of the airbag is fixedly connected with multiple rubber protrusions, and the surface of the rubber protrusions is in contact with the inner wall of the annular groove.

[0013] Furthermore, the cutting assembly includes a mounting bracket fixedly connected to the surface of the connecting frame. Two electro-hydraulic actuators are fixedly connected to the upper end of the mounting bracket. The lower end of the electro-hydraulic actuators extends through the inner side of the mounting bracket. The telescopic end of the electro-hydraulic actuator extends through the inner side of the support plate and is fixedly connected to a connecting block. Two guide rods are slidably connected to the inner wall of the connecting block. A rubber plate is fixedly connected to the lower end of the guide rods. A cutting blade is fixedly connected to the lower end of the connecting block.

[0014] Furthermore, the lower end of the connecting block has a circular hole, and a spring is sleeved on the surface of the guide rod, with the upper end of the spring fixedly connected to the inner top wall of the circular hole.

[0015] Furthermore, the lower end of the rubber plate contacts the inner bottom wall of the support plate, and the horizontal cross-section of the rubber plate is rectangular.

[0016] Furthermore, the lower end of the mounting bracket is fixedly connected to two partitions, which are fixedly connected to the inner bottom wall of the support plate.

[0017] Beneficial effects

[0018] The aforementioned automatic headband cutting machine uses the contact between the annular groove of the agitator roller and the rubber protrusions on the surface of the airbag to provide an auxiliary clamping effect for the cut headbands. When the airbag and the agitator roller rotate, it ensures stable conveying of the headbands. The guide groove enables directional conveying of the cut headbands. The comb-shaped strips help prevent the headbands from shifting during the conveying process after cutting, ensuring the stability of the headband conveying, reducing the likelihood of shifting after batch cutting, reducing the occurrence of headband shifting and entanglement, and ensuring the conveying effect.

[0019] The device uses a partition at the lower end of the mounting frame to separate the head straps, drives the telescopic end of the electro-hydraulic actuator to move downward, and causes the connecting block to move the cutting blade downward as well. The cutting blade cuts the head straps, and during the cutting operation, the rubber plate contacts the head straps first. At the same time, the rubber plate and the head straps are vertically staggered, so that the two rubber plates press and position the head straps on both sides of the cut.

It is a cutting equipment in the production line or an intelligent cutting workstation. Its core functions include precise length control, continuous cutting and material positioning. In the production of headbands in the fields of medical and sports protective gear, the headband material to be cut is printed, hot-pressed, and laminated, and the surface of the headband is free of wrinkles, stains or damage. It will then be conveyed to the cutting mechanism 3 for cutting operation.

[0031] In some embodiments, such as Figure 1-3As shown, in a preferred embodiment of the present invention, the guide conveying assembly 31 includes a connecting frame 311 fixedly connected to the inner side of the positioning frame 1.

The grooves are distributed in a ring along the surface of the actuating roller 314 and are connected to the annular grooves. The surface of the rotating shaft 315 is fixedly connected to the connecting bracket 316. The inner side of the connecting bracket 316 is fixedly connected to the surface of the airbag 317. The surface of the airbag 317 is fixedly connected to multiple rubber protrusions, and the surface of the rubber protrusions is in contact with the inner wall of the annular groove.

[0033] In this embodiment of the invention, the device uses a servo motor 2 to drive the drive shaft 313 to rotate synchronously.
