[0002] The rubber band machine is a mechanical device used to splice rubber bands. It is widely used in many industries such as textiles, clothing, and household goods.

[0003] Elastic band machines can be divided into various types according to their functions and uses, such as multi-needle machines, automatic elastic band splicing machines, ultrasonic elastic band splicing machines, etc. Among them, automatic elastic band splicing machines can automatically cut and tighten the elastic bands, and then splice the elastic bands into the required length and shape. They are used to make elastic bands for sports pants and casual pants, as well as shirt platoons and decorative strips. They can greatly reduce manual operations and improve production efficiency and product quality.

[0004] However, when using a traditional rubber band machine, the rubber band is only flattened by gravity and a positioning wheel. When the running speed is too fast, the rubber band will still be twisted and stuck, which greatly affects the feeding efficiency and further affects the processing efficiency of the rubber band splicing. Therefore, in order to solve the above problems, a rubber band machine with easy feeding is proposed. Utility Model Content

[0025] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] See also Figure 1-3 As shown, a rubber band machine that is easy to load includes a body 1, a loading rack 2, a rubber band 4 and a positioning mechanism 3. The loading rack 2 is fixedly mounted on the surface of the body 1 and is used to convey the rubber band 4;

[0028] The positioning mechanism 3 is provided on the surface of the loading rack 2 and is used for positioning the rubber band 4;

[0029] The positioning mechanism 3 includes a fixed block 5, which is fixedly mounted on the surface of the loading rack 2. A slide plate 6 is provided in the fixed block 5. Two slide plates 6 are provided, and a pair of slide plates 6 are symmetrically distributed about the central axis of the fixed block 5.

[0030] A pair of slide plates 6 are rotatably connected to a guide plate 11 and a guide plate 2 17 on their surfaces through connecting pieces, and a telescopic mechanism is provided between the guide plate 11 and the guide plate 2 17;

[0031] A pair of slides 6 are fixedly connected to the surface of the bracket 16, and a guide piece 15 is rotatably provided on the surface of the bracket 16;

[0032] During operation, the rubber band 4 is passed through the guide piece 15 and fitted on the telescopic mechanism, and then the rubber band 4 is fed into the machine, the rubber is precisely positioned by mechanical or electronic devices, and cut according to the set length, and finally the cut rubber segments are spliced ​​by the machine needle. When the rubber band 4 is fed, the rubber band 4 will rotate on the main rod 13 and the auxiliary rod 14, and at the same time drive the guide plate 11 and the guide plate 2 17 to rotate. Because the surfaces of the guide plate 11 and the guide plate 2 17 are both provided with bevels, the rubber band will be accurately stuck between the guide plate 11 and the guide plate 2 17. The rubber band can be flattened through the guide piece 15, and when passing through the guide plate 11 and the guide plate 2 17, there will be no twisting or jamming, which ensures the feeding efficiency and indirectly improves the processing efficiency of the splicing of the rubber band 4.

[0033] A cavity 10 is provided on the surface of the fixed block 5, and a limit column 12 is fixedly connected to the surface of each slide plate 6. The end of the limit column 12 away from the slide plate 6 passes through the side wall of the cavity 10 and is slidably connected by a spring. A pull rope 9 is fixedly connected to the side where the two slide plates 6 are close to each other. A fixing mechanism is provided on the pull rope 9. The connecting member is a ball bearing 18, which is used to reduce the friction generated when the guide plate 11, the guide plate 2 17 and the slide plate 6 rotate. The pull rope 9 is a rigid rope. The telescopic mechanism includes a main rod 13 and a sub-rod 14. The main rod 13 is fixedly connected to the surface of the guide plate 11, and the sub-rod 14 is fixedly connected to the surface of the guide plate 2 17. There are multiple main rods 13 and sub-rods 14, and they are comb-shaped. The main rod 13 and the sub-rod 14 are plugged into each other.

[0034] During operation, the knob 7 is turned to drive the rotating shaft 8 to rotate through the knob 7. At the same time, the rotating shaft 8 will stretch the pull rope 9 on the surface, so that the pull rope 9 drives the two slides 6 to rotate in the direction of approaching each other. When the slide 6 moves, the spring will be stretched to generate elastic force. When the slide 6 moves, it will drive the guide plate 11 and the guide plate 2 17 to approach each other, so that the main rod 13 and the auxiliary rod 14 are inserted into each other. Conversely, the knob 7 is loosened, so that the spring pulls the slide 6 to slide in the direction away from each other, so that the two guide plates move in the direction away from each other, and at the same time, the main rod 13 and the auxiliary rod 14 are driven to expand. Through the cooperation of the main rod 13 and the auxiliary rod 14, the positioning mechanism 3 can adapt to rubber belts of various widths, which greatly improves the practicality of the rubber band machine.

[0035] The fixing mechanism includes a rotating shaft 8, which is rotatably connected to the surface of the fixed block 5, and the end portion thereof passes through the cavity 10 for rotational connection. The other end of the rotating shaft 8 is fixedly connected to a knob 7, and an anti-slip groove is provided on the surface of the knob 7. The rotating shaft 8 is arranged in the middle position of the pull rope 9, and the pull rope 9 is fixedly connected to the surface of the rotating shaft 8. A protective cover 19 is provided on the surface of the rotating shaft 8. The end portion of the rotating shaft 8 located inside the protective cover 19 is fixedly connected to a bottom plate 20, and the bottom plate 20 and the protective cover 19 are connected by a spring. A shift block 21 is fixedly connected to the inner wall of the protective cover 19, and an extrusion block 22 is fixedly connected to the surface of the bottom plate 20. An oblique angle is provided at the position where the shift block 21 and the extrusion block 22 fit together. A sliding rod is fixedly connected to the surface of the protective cover 19, and the end of the sliding rod away from the protective cover 19 passes through the cavity 10 for sliding connection, and the cross section of the sliding rod is rectangular.

[0036] During operation, the rotation of the rotating shaft 8 will drive the bottom plate 20 to rotate, and the extrusion block 22 on the surface of the bottom plate 20 will squeeze the shift block 21. The direct inclined surfaces of the shift block 21 and the extrusion block 22 squeeze each other, causing the protective cover 19 to move upward. When the extrusion block 22 passes the shift block 21, the spring drives the protective cover 19 to reset, and cooperates with the rectangular slide bar to limit the rotating shaft 8 to prevent reversal, and then position the pull rope 9, and also position the width between the guide plate 11 and the guide plate 2 17. When the distance needs to be widened, the slide bar is directly pushed upward to disengage the shift block 21 and the extrusion block 22, and then, driven by the springs on both sides of the slide plate 6, the guide plate 11 and the guide plate 2 17 are pulled in the direction away from each other. The width between the guide plate 11 and the guide plate 2 17 can be quickly adjusted by the spring, the rotating rod, the extrusion block 22 and the shift block 21.

[0037] Example 2

[0038] See also Figure 4 As shown, compared with Example 1, as another embodiment of the present invention, notches 23 are provided on the surfaces of the main rod 13 and the auxiliary rod 14; during operation, the notches 23 provided on the surfaces of the main rod 13 and the auxiliary rod 14 can increase the friction between the rubber band 4 and the main rod 13 and the auxiliary rod 14, thereby avoiding the situation where the rubber band 4 only slides on the surfaces of the main rod 13 and the auxiliary rod 14, causing unnecessary wear.
