Description

Technical Field

[0001] The present application relates to the technical field of overlock machines, and in particular to a material arrangement mechanism and an overlock machine. Background Art

[0002] Overlocking is also called lock edge, a term in the clothing industry. In the process of producing clothing, since the materials used, such as polyester, are generally synthetic fibers with relatively hard texture, after cutting, the silk threads at the seams of the cut clothes will spread out due to their high hardness, so overlocking is required. A special overlocking machine is used to overlock a circle of edges at the seams to prevent the silk threads in the fabric from spreading out, which also serves to make the clothes look beautiful.

[0003] In the process of overlocking, the uneven edges of the fabric are often cut off, resulting in some scraps. If these scraps are not cleaned up in time, they will accumulate around the overlocking machine, which is easy to hinder the fabric products in the process of overlocking. In the existing process, a discharge port is generally opened through the machine, and the bottom of the discharge port is connected to a discharge channel, and the cut scraps are discharged from the discharge channel. Since the discharge port is located on the side of the cutting head of the overlocking machine, in order to prevent the discharge channel from affecting the operation of the workers (the workers sit next to the machine with their feet under the machine), the discharge channel is generally set at an angle. During the cutting process, the scraps are gradually cut. The overlapping ends slide down in the discharge channel by their own gravity. Since the cloth is cut at a fast speed and some cloth is light in material, there is a certain friction resistance when the cloth is overlapped with the discharge channel. When the cutting is too fast, the scraps are produced quickly and are longer, so that the scraps cannot fall quickly, and are bent and twisted under the stress generated by the gradual lengthening and placed horizontally on the workbench, so that they cannot be discharged smoothly through the discharge channel. The staff needs to manually push them to fall, which affects the processing efficiency. At the same time, when too much scraps are placed on the workbench, it also affects the normal work of the overlocking. Therefore, the present application proposes a discharge mechanism and an overlocking machine. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0008] The discharge channel has an inclined channel and a vertical channel that are connected to each other. The inclined channel is connected to the discharge port. The bottom of the vertical channel is connected to a collecting box. The inner bottom wall of the discharge channel is connected to a shell. Transmission rollers are rotatably passed through the opposite sides of the inner walls at both ends of the shell. The end of one of the transmission rollers is connected to a motor arranged on the shell. Conveyor belts are driven and wound around the two transmission rollers. The upper transmission surface of the transmission belt is flush with the inner bottom wall of the inclined channel.

[0009] Furthermore, an exhaust pipe is connected to a side of the vertical channel away from the inclined channel, an exhaust fan is arranged in a free end of the exhaust pipe, and a filter is arranged in a connecting port between the exhaust pipe and the vertical channel.

[0010] Furthermore, a vertical rod is movably inserted at the top of the vertical track, a scraper overlapped with the filter screen is arranged at the bottom of the vertical rod, and a linkage is arranged on the vertical track.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 5As shown, a discharge mechanism proposed in an embodiment of the present application includes: a machine table 1, on the top of which a discharge port 2 is provided; a discharge channel 3, which has an inclined channel 301 and a vertical channel 302 connected to each other, the inclined channel 301 is connected to the discharge port 2, and the bottom of the vertical channel 302 is connected to a collection box 4, the discharge channel 3 includes the connected inclined channel 301 and the vertical channel 302, which is not only convenient for the discharge of scraps, but also does not affect the workers' sitting, and the bottom of the machine table 1 is convenient for the workers' feet to rest, and the collection box 4 is a box body A collection frame is movably inserted and pulled out on one side of the box body, and the inner bottom wall of the discharge channel 3 is connected to a shell body 5. Transmission rollers 6 are rotatably penetrated on opposite sides of the inner walls at both ends of the shell body 5. One end of one of the transmission rollers 6 is connected to a motor 7 arranged on the shell body 5. A transmission belt 8 is wound around the two transmission rollers 6. The upper transmission surface of the transmission belt 8 is flush with the inner bottom wall of the inclined channel 301. Preferably, the motor 7 adopts a micro motor. When overlocking, one end of the cut scraps will slide through the discharge port 2 and overlap in the inclined channel 301. The end will overlap on the conveyor belt 8, the motor 7 works, and its output shaft drives one of the conveyor rollers 6 to rotate, and with the cooperation of the other conveyor roller 6, the conveyor belt 8 is driven to transmit. When the conveyor belt 8 transmits, it will drive the scraps placed on it to slide down quickly obliquely, thereby driving the scraps into the vertical track 302. When the scraps are in the vertical track 302, they fall quickly by their own gravity and fall into the collection box 4. Through the set conveyor belt 8, the auxiliary transmission of the conveyor belt 8 is used to make the cloth When the material is being cut, even if the cutting speed is fast and scraps are produced quickly, the scraps can slide down quickly due to the transmission of the conveyor belt 8, so that they will not stay due to the friction generated by the contact with the inner wall of the inclined path 301. When the scraps slide down quickly, they will not be placed horizontally on the table due to the stress caused by the lengthening of the cutting. There is no need to manually fiddle with the scraps too much later, thereby improving the processing efficiency. At the same time, as the cutting proceeds, the work table will not retain too much scraps, and will not affect the normal work of the overlocking, thereby improving practicality.

[0026] like Figure 2 and Figure 5As shown, in some embodiments, the side of the vertical channel 302 away from the inclined channel 301 is connected to an exhaust pipe 9. Preferably, the exhaust pipe 9 is coaxially arranged with the inclined channel 301, and an exhaust fan 10 is arranged in the free end of the exhaust pipe 9. A filter screen 11 is arranged in the connecting port between the exhaust pipe 9 and the vertical channel 302. When the cloth is overlocked and the cloth is cut, some thread debris will be generated, and some thread debris will slide toward the discharge port 2 with the scraps, but some thread debris will remain on the table 1 and at the overlock head of the overlock machine. When too much thread is left, it will affect the normal operation of the overlock. An exhaust duct 9 is connected to the conveyor belt, in which an exhaust fan 10 is arranged. When the overlocking is performed, the exhaust fan 10 works to discharge the airflow in the inclined channel 301 to the outside, so that the airflow in the inclined channel 301 can circulate quickly, so that the inclined channel 301 and the discharge port 2 have suction. Through the suction, the thread ends and debris generated by the overlocking cutting can be effectively absorbed, and then discharged to the collection box 4 through the discharge channel 3. At the same time, the suction can also accelerate the sliding speed of the scraps, thereby improving the practicality. The filter 11 is arranged to block the thread ends and debris to prevent them from being drawn into the exhaust fan 10.

[0027] like Figure 5 As shown, in some embodiments, a vertical rod 12 is movably inserted at the top of the vertical channel 302, and a scraper 13 overlapping the filter 11 is provided at the bottom end of the vertical rod 12. A linkage 14 is provided on the vertical channel 302. When one of the transmission rollers 6 rotates, the linkage 14 drives the vertical rod 12 to slide back and forth up and down. Since the exhaust fan 10 generates suction, the thread ends of lighter materials are easily attached to the filter 11 under the action of suction, thereby affecting the air volume and reducing the suction. By sliding the vertical rod 12 and the scraper 13, when the transmission roller 6 rotates, the linkage 14 is used to drive the vertical rod 12 to slide back and forth up and down, so that the scraper 13 scrapes the filter 11, effectively scraping off the thread ends attached to the filter 11 due to the suction, thereby improving practicality.

[0028] like Figure 5 As shown, in some embodiments, the linkage 14 includes a rotating shaft 1401 rotatably arranged at the top of the vertical track 302, a rack 1402 is arranged on the vertical rod 12, a half gear 1403 meshing with the teeth of the rack 1402 is fixedly arranged on the rotating shaft 1401, and a pulley assembly 1404 is connected between the rotating shaft 1401 and one of the transmission rollers 6. When the transmission roller 6 rotates, the rotating shaft 1401 is driven to rotate synchronously through the pulley assembly 1404, thereby driving the half gear 1403 to rotate, and utilizing the meshing of the teeth of the half gear 1403 and the rack 1402 to drive the vertical rod 12 to slide. Since the outer peripheral side of the half gear 1403 has only half of the teeth, after the half gear 1403 rotates half a circle, it drives the vertical rod 12 to slide upward, and it automatically disengages from the rack 1402, and then the vertical rod 12 falls by its own gravity, thereby realizing the effect of reciprocating sliding up and down.

[0029] like Figure 1 and Figure 4 As shown, in some embodiments, the discharge port 2 is constructed as a conical expansion port, and one end of the inclined channel 301 away from the vertical channel 302 is embedded in the inner wall of the discharge port 2. The design of the conical expansion port allows the cut scraps to fall into the discharge port 2 more quickly. The inclined channel 301 is partially embedded in the discharge port 2, so that when the scraps fall into the discharge port 2, they can contact the conveyor belt 8 more quickly, thereby further improving the discharge efficiency of the scraps.

[0030] like Figure 4 As shown, in some embodiments, a plurality of convex strips 15 are constructed in an array along the transmission surface of the conveyor belt 8. The plurality of convex strips 15 are constructed to increase the friction between the scraps and the conveyor belt 8, so that the conveyor belt 8 can drive the scraps to fall off more quickly during transmission.

[0031] like Figure 3 As shown, in some embodiments, the end of the shell 5 with a lower inclination is connected to the vertical channel 302. When the thread end slides in the inclined channel 301, part of the thread end will fall into the shell 5. Since the shell 5 is inclined, the end of the shell 5 with a lower inclination is connected to the vertical channel 302. Therefore, the thread end that falls into the shell 5 can slide into the vertical channel 302 and will not remain in the shell 5, thereby improving practicality.

[0032] like Figure 1 and Figure 2 As shown, the overlock machine proposed in one embodiment of the present application also includes a machine head 16, which is arranged on the top surface of the machine table 1, and the overlock head of the machine head 16 is located on one side of the discharge port 2. The machine head 16 is used to overlock the cloth and cut the scraps. The overlock head is located on one side of the discharge port 2, so that the scraps produced by the overlock cutting can fall into the discharge port 2 more quickly.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
