Description

Technical Field

[0001] The utility model belongs to the technical field of elastic band machines, and particularly relates to a material receiving mechanism of a new type of elastic band machine. Background Art

[0002] Elastic bands, also known as stretch bands, can be used as the bottom line of clothing accessories when they are thinner. They are especially suitable for the production of clothing products such as underwear, trousers, baby clothes, sweaters, sportswear, dance costumes, wedding dresses, T-shirts, hats, bras, masks, etc.

[0003] For the automated production of elastic loops, generally, bundled or rolled elastic bands are used as raw materials. The elastic bands are cut into fixed-length elastic band segments by a fixed-length cutting device, and then the elastic band segments are wound into loops by a coiling device. Then, the coiled elastic band segments are conveyed to a sewing device, and the sewing device is used to sew and seal the edges of the elastic band segments to finally obtain a circular elastic band. After the circular elastic band is formed, it needs to be unloaded. In the prior art, generally, a material receiving tray is used to complete the unloading of the elastic band. A plurality of receiving rods are arranged around the material receiving tray. During the rotation of the receiving rods around the material receiving tray, the circular elastic band is collected and unloaded by directly falling into the receiving rods. The material receiving tray is usually integrally arranged on the elastic band machine, and during the assembly process, the material receiving tray needs to be separately installed on the elastic band machine, which is a rather troublesome process, inconvenient to install, and has a low material receiving efficiency.

And one end of the movable support 402 away from the blanking swing rod 403 extends through the movable slot 301 to the lower side of the turntable 3 to form a pushing part 404. The fixed support 401 is installed on the turntable 3 by means of threaded fixation and is placed corresponding to the movable slot 301. It is mainly used to fix the movable support 402 and play a limiting role, enabling the movable support 402 to rotate within the movable slot 301 through the fixed support 401, and driving the blanking swing rod 403 thereon to expand outwards to the sewing position 1001 through the rotation of the movable support 402.

[0042] The driving cylinder 5 is installed within the material receiving base 1. The pushing end of the driving cylinder 5 extends out of the upper surface of the material receiving base 1.

[0046] A limiting portion is formed on one side of the fixed support 401 away from the rotating groove 405 to prevent the movable support 402 from deviating inwardly. The movable support 402 is rotated in the fixed support 401 via a pin shaft.

[0047] The upper surface of the movable support 402 is provided with a mounting hole, and the unloading swing rod 403 is fixed on the movable support 402 through the mounting hole.

[0048] A guide head is provided at the upper end of the material discharge swing rod 403. In this embodiment, when the annular elastic band is sewn at the sewing position 1001, its opening is arranged in the left-right direction. When the annular elastic band is pushed out of the sewing position 1001 by the external push auxiliary device 9, the material receiving mechanism is in the material receiving state. At this time, the upper end of the material discharge swing rod 403 is located at one side of the sewing position 1001. After the annular elastic band falls downward, it will enter the material discharge swing rod 403 through the guide head.

[0049] like Figure 1 As shown: the material receiving base 1 includes an outer frame 101, a mounting plate 102 and a bottom plate 103. The mounting plate 102 and the bottom plate 103 are respectively fixed at the upper and lower ends of the outer frame 101. The mounting plate 102 is provided with a first through hole for the output end of the driving motor 2 to pass through and a second through hole for the driving end of the driving cylinder 5 to pass through. The material receiving base 1 is cylindrical and has a small overall volume for easy movement. A support leg is formed under the bottom plate 103. The outer frame 101 is used to protect the internal driving motor 2 and the driving cylinder 5.

[0050] The first through hole is provided with a base motor plate for fixing the driving motor 2, and a bearing assembly is also provided on the upper end of the base motor plate, and the turntable 3 is connected to the driving motor 2 through the bearing assembly. The bearing assembly includes a turntable bearing shaft fixed to the lower surface of the turntable 3 and a turntable bearing sleeve fixed to the mounting plate 102, the turntable bearing sleeve is sleeved outside the turntable bearing shaft, and the turntable bearing shaft is connected to the output end of the driving motor 2 through the transmission, and a sensor for positioning the swing arm mechanism 4 is also provided on the base motor plate.

[0051] like Figures 4-5 As shown: The push-out assist device includes:

[0052] Mounting plate 901, mounted on the head of sewing machine 10;

[0053] A driving source is mounted on the mounting plate 901 and is located on one side of the sewing position 1001;

[0054] The pushing block is linked to the driving source.

[0055] As Figure 5 shown: The driving source includes a first air cylinder 902 and second air cylinders 903 arranged on the front and rear sides of the first air cylinder 902. Among them, the pushing block linked to the first air cylinder 902 is the first pushing block 904, and the pushing block linked to the second air cylinder 903 is the second pushing block 905. The first pushing block 904 is used to push the upper side of the annular elastic band, and the two second pushing blocks 905 are used to push the front and rear sides of the annular elastic band respectively.

[0056] The working principle of the external pushing auxiliary device 9: After the sewing head 10 finishes sewing the interface of the annular elastic band, the first air cylinder 902 and the second air cylinders 903 work together. The first air cylinder 902 drives the first pushing block 904 to push the upper side of the annular elastic band, and the second air cylinders 903 drive the two second pushing blocks 905 to push the front and rear sides of the annular elastic band respectively, so as to push the annular elastic band away from the sewing position 1001.

[0057] The working principle and process of the present utility model are as described below:

[0058] When material collection is required, the driving air cylinder 5 works. The pushing end of the driving air cylinder 5 jacks up the pushing part 404 of the movable support 402 located at the lower end of the movable groove 301, so that the movable support 402 rotates outward relative to the movable groove 301 through the fixed support 401, which can drive the blanking swing rod 403 fixed on the movable support 402 to rotate synchronously. When the pushing end of the driving air cylinder 5 drives the movable support 402 to move back and forth, the blanking swing rod 403 switches back and forth between the material receiving state and the material collection state, so as to continuously collect the annular elastic band falling from the sewing position 1001 onto the blanking swing rod 403. After a sufficient number of annular elastic bands are placed on the blanking swing rod 403, the driving air cylinder 5 stops working; then, the driving motor 2 works, and the output end of the driving motor 2 starts to rotate, that is, drives the turntable 3 fixed on the output end to rotate synchronously, and moves another blanking swing rod 403 that has not received material to the position corresponding to the sewing position 1001 for the next round of material collection. The present utility model is provided with a material collection base 1. The material collection base 1 can be placed at any position without being fixedly installed on the rubber band machine frame. When in use, it only needs to be placed beside the rubber band machine frame so that one of the blanking swing rods 403 corresponds to the sewing position 1001. And when a sufficient number of annular elastic bands are placed on one of the blanking swing rods 403, by rotating the turntable 3 with the driving motor 2, another blanking swing rod 403 can be moved to the sewing position 1001 to continuously collect the annular elastic band, thereby increasing the material collection efficiency and solving the technical problems of inconvenient installation of the material collection mechanism of the existing rubber band machine and low material collection efficiency.

[0059] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
