Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a memory elastic sorting device. Background Art

[0002] In the clothing industry, in order to increase the elasticity of clothes, many clothes will use rubber bands, such as the contraction force of rubber bands to achieve the tightening of collars and cuffs. The rubber band has a certain elasticity and can shrink after being stretched, and the elastic band after shrinking is the same as the original without deformation. This kind of rubber band is also called memory rubber band. The production process of rubber band rings usually uses bundles or rolls of rubber bands as raw materials, cuts them in sections, and sews them into rings through rubber band machines. In the batch production process, it is easy to have loose connections and easy to break, and the quality is not up to standard. This kind of memory rubber band is used on clothes, which will lead to unqualified situations. Therefore, it is necessary to sort the produced memory rubber bands one by one to ensure product quality. In this way, the labor intensity of workers is greatly increased, and the efficiency is relatively low. Therefore, the inventor proposes a sorting device for memory rubber bands, which improves the sorting efficiency of memory rubber bands and reduces the labor intensity of manual labor by batch sorting memory rubber bands.

[0003] In order to improve the sorting efficiency of rubber bands, the rubber bands are automatically detected, bundled and packaged. A Chinese patent (authorization announcement number: CN219771177U) discloses a rubber band sorting device for a rubber band joining machine. The utility model includes a grabbing table, a flat-laying table and a stacking area. The grabbing table is arranged at the sewing station of the rubber band joining machine. The grabbing table is provided with a first manipulator for grabbing the rubber band ring at the sewing station and a first moving mechanism for driving the first manipulator to move. The flat-laying table is provided with a second manipulator and a second moving mechanism for driving the second manipulator to move. The stacking area is arranged on one side of the flat-laying table. The flat-laying table is also provided with a flat-pushing mechanism for pushing the rubber band ring to the stacking area. The utility model grabs and moves the rubber band ring to the flat-laying table by a first mechanical claw, and then the second mechanical claw clamps the rubber band ring and lays it flat on the flat-laying table. Finally, the flat-pushing mechanism pushes the rubber band ring horizontally into the stacking area for neat stacking, thereby realizing the automatic stacking operation after the rubber band ring is sewn, without manual sorting, and with high efficiency.

[0004] This solution still has some shortcomings in application. Since memory rubber bands are mass-produced and usually in large quantities, if they are tested one by one, the detection efficiency is still too low and cannot meet production needs. Therefore, it is necessary to improve the structure of the memory rubber band sorting device so that it has an efficient sorting function and can sort memory rubber bands in batches to reduce the labor intensity of workers.

[0023] The specific implementation of the present utility model will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 7As shown in the figure, a sorting device for memory rubber bands includes a frame 1, a sorting device 2, and memory rubber bands 3. A plurality of multi-stage lifting cylinders 4 are provided at the bottom of the frame 1. Above the multi-stage lifting cylinders 4, there is a chassis groove 5. The chassis groove 5 is provided with a plurality of openings. At the top of the openings, there are telescopic rods 6. The sorting device 2 is installed at the top of the telescopic rods 6 and is drivingly connected to the multi-stage lifting cylinders 4. The sorting device 2 includes a base 21 and a moving needle 22. On the left and right sides inside the base 21, there are telescopic cylinders 23 installed, and a slide rail 24 is provided at the top. The moving needle 22 includes a left half needle 7 and a right half needle 8. The bottoms of the left half needle 7 and the right half needle 8 are respectively drivingly connected to the telescopic cylinders 23. The memory rubber bands 3 are sleeved on the moving needle 22 and can be stretched through the left half needle 7 and the right half needle 8.

[0025] Furthermore, the openings are arranged in a straight line. Below the openings, there is a "mountain"-shaped telescopic frame 9. The top of the telescopic frame 9 is arranged corresponding to the sorting device 2, and the middle bottom is connected to the multi-stage lifting cylinders 4.

[0026] Furthermore, the sorting device 2 can slide up and down through the multi-stage lifting cylinders 4, and the upward sliding height can be higher than the top of the chassis groove 5.

[0027] Furthermore, the top of the moving needle 22 is in a conical shape.

[0028] Furthermore, the left half needle 7 and the right half needle 8 can move symmetrically left and right along the slide rail 24 through the telescopic cylinders 23.

[0029] Furthermore, the base 21 is in a conical shape.

[0030] Furthermore, oscillators 10 are installed on the left and right sides inside the chassis groove 5.

[0031] [Embodiment]

[0032] First, pour the memory rubber bands into the chassis groove 5 in batches. At this time, the sorting device 2 is at the bottom of the chassis groove 5, and the moving needle 22 of the sorting device 2 is in a closed state. Then, the multi-section lifting cylinder 4 is started. The multi-section lifting cylinder 4 lifts the sorting device 2 upward through the "mountain"-shaped telescopic frame 9. The moving needle 22 of the sorting device 2 penetrates a plurality of memory rubber bands 3 during the rising process. The penetrated memory rubber bands 3 are lifted up. Since the base 21 is in a conical shape, the memory rubber bands that have not been penetrated will fall into the chassis groove 5 again. Finally, the telescopic cylinder 23 inside the base 21 is started. Through the telescopic cylinder, the memory rubber bands 3 are lifted up. 23 separates the left half needle 7 and the right half needle 8 to the left and right sides, and the memory rubber band 3 brought by the moving needle 22 is stretched to perform a stretching test. During the stretching process, the memory rubber band with poor quality breaks and falls into the chassis groove 5, and the unbroken memory rubber band 3 waits to be collected. Since there are several sorting devices 2 and one sorting device may insert several memory rubber bands 3 at a time, multiple memory rubber bands can be tested at one time. The sorting device 2 reciprocates and lifts the memory rubber band 3 through the multi-section lifting cylinder 4 to perform a stretching test. At the same time, each time it is lifted, the oscillators 10 on both sides of the chassis groove 5 are also started to vibrate the memory rubber band 3.

[0033] It can be seen from the above description of the utility model that, compared with the prior art, the advantages of the utility model are:

[0034] The utility model firstly arranges sorting devices corresponding to the openings of the chassis grooves, and the sorting devices can be lifted up and down by the multi-section lifting cylinders at the bottom of the chassis grooves. At the same time, the sorting device is composed of a conical base and a moving needle in the middle of the top of the base. The memory rubber band is cyclically inserted by the moving needle by lifting and lowering, so as to prepare for the next test; then, the moving needle is divided into a left half needle and a right half needle, and the left half needle and the right half needle are both connected to the telescopic cylinder drive and can be separated to the left and right sides, so that the memory rubber band inserted on the moving needle is stretched to realize the test. Since there are several sorting devices and the moving needle can insert multiple memory rubber bands at a time, multiple memory rubber bands can be tested at a time. Compared with the method of testing one by one, the testing efficiency of the scheme is significantly improved; finally, after taking the memory rubber band that can pass the stretching test, the left half needle and the right half needle are restored to their original state first, and then the sorting device is lowered downward, and the next batch of insertion and stretching tests are continued. The operation is simple and the practicability is strong. The utility model has a novel structure and an ingenious design, can improve the sorting efficiency of memory rubber bands, and is suitable for promotion.

[0035] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial improvement of the utility model using this concept should be regarded as an infringement of the protection scope of the utility model.
