Description

Technical Field

[0001] The utility model relates to the technical field of rubber band machines, and particularly refers to a material arranging device for a rubber band machine. Background Art

[0002] In the production of rubber bands, the usual production process is to use bundled or rolled rubber bands as raw materials, cut them into sections and sew them into circles. In this production process, it is usually completed by manual operation or separate operation of multiple single machines with different functions.

[0003] Before the rubber band enters the feeding device for transportation from the material pile, due to problems such as initial stacking and uneven material of the rubber band, the rubber band is uneven, wrinkled, creased, etc. Therefore, it is necessary to straighten and smooth the rubber band through a material arranging device.

[0004] For example, an automatic rubber band machine disclosed in Chinese Patent CN201920429727.X has a fixed plate arranged at the lower end of the first frame, an induction frame arranged at the lower end of the fixed plate, and a laser sensor arranged at the upper end of the induction frame, using the laser sensor to sense the feeding and position of the rubber band material; however, there are some deficiencies in this method. Since the rubber band is blown by the wind and triggers the sensor, the machine continuously feeds the material, resulting in excessive feeding and stacking of the rubber band, affecting the flatness of the rubber band; at the same time, when the rubber band gets stuck, the machine will continue to run, causing the rubber band to be pulled and deformed or even broken, affecting the yield rate of the rubber band after sewing into a rubber band circle. Summary of the Invention

[0005] The purpose of the utility model is to provide a material arranging device for a rubber band machine, which realizes the start and stop control of the rubber band machine by the contact between the induction part at the rear end of the material guiding rod and the first induction area and the second induction area of the induction device, and improves the problem that the induction device is accidentally triggered and continuously feeds the material.

Detailed Embodiments

[0040] The following further elaborates on the specific implementation manners of the present utility model in conjunction with the accompanying drawings. Refer to Figure 1 and Figure 2 .

[0041] A material arranging device of an elastic band machine, comprising: a material arranging frame 21; a shaping plate assembly 22, which is installed in the material arranging frame 21, and a shaping channel 221 is vertically arranged in the shaping plate assembly 22; a material pushing component 23, which is arranged at the upper end of the material arranging frame 21 and is used to send the elastic band to the upper end of the shaping channel 221; a driving pressure wheel assembly 24, which is arranged on the material arranging frame 21 below the shaping channel 221; a material guiding rod 25, the middle part of which is rotatably arranged on the material arranging frame 21 below the driving pressure wheel assembly 24, and a material guiding opening 251 for the elastic band to pass through is provided at the front end of the material guiding rod 25, and an induction part 250 is provided at the rear end of the material guiding rod 25; an induction device 26, which is arranged on the material arranging frame 21 corresponding to the movement track of the induction part 250, and the induction device 26 has a first induction area 261 and a second induction area 262; the middle part of the material guiding rod 25 is hinged to the material arranging frame 21 through a hinge seat. When the material guiding rod 25 rotates, the induction part 250 will rotate around the hinge seat to form the movement track of the induction part 250, and the induction device 26 is arranged on the material arranging frame 21, and both the first induction area 261 and the second induction area 262 are located on the movement track of the induction part 250, so that the first induction area 261 and the second induction area 262 can sense the induction part 250.

[0042] When the material guiding rod 25 rotates, the induction part 250 cooperates with the first induction area 261 or the second induction area 262 to control the start and stop of the elastic band machine; when the elastic band is conveyed by the feeding device 3, since the length of the elastic band between the feeding device 3 and the driving pressure wheel assembly 24 gradually decreases, the elastic band will lift the material guiding opening 251 at the front end of the material guiding rod 25, so that the material guiding rod 25 rotates, and the induction part 250 is placed in the first induction area 261. After the induction device 26 senses the induction part 250 through the first induction area 261, it will make the material pushing component 23 work to push the elastic band, so as to realize the feeding of the elastic band. Only after the first induction area 261 senses the induction part 250, will the material pushing component 23 work to feed the elastic band.

[0043] When the elastic band is stuck due to reasons such as not being straightened, the length of the elastic band further decreases due to untimely supply, resulting in the induction part 250 being placed in the second induction area 262. After the induction device 26 senses the induction part 250 through the second induction area 262, it will make the whole machine stop working. At this time, after the elastic band is straightened manually, the induction part 250 disengages from the second induction area 262, and the induction device 26 makes the elastic band machine work again; the induction device 26 can feed the elastic band in time, and can also prevent the elastic band from being broken when the machine is still running after the elastic band is stuck, ensuring the safety and stability of the feeding.

[0044] The material shifting assembly 23 includes: a connecting frame 231, which is installed on the upper end of the material sorting frame 21; a triangular rotating wheel 232, which is rotatably connected to the connecting frame 231; a second driving member 233 (a motor or a rotary cylinder), which is installed on the connecting frame 231 and is used to drive the triangular rotating wheel 232 to rotate; a smoothing rod 1 234, which is installed on the connecting frame 231; a smoothing rod 235, which is installed on the connecting frame 231; when the rubber band moves between the smoothing rod 1 234 and the smoothing rod 235 through the triangular rotating wheel 232, the smoothing rod 1 234 presses against the upper end surface of the rubber band, and the smoothing rod 2 235 presses against the lower end surface of the rubber band, so as to smooth the rubber band.

[0045] The second straightening rod 235 is provided with two limiting members 236 for limiting the elastic band from being separated from the second straightening rod 235 .

[0046] A roller three 252 is sleeved on one side edge of the material outlet 251. When the elastic band moves, the roller three 252 rotates, thereby reducing the friction between the elastic band and the edge of the material outlet 251, avoiding deformation of the elastic band caused by pulling the elastic band.

[0047] The shaping plate assembly 22 includes: a shaping plate 1 222, which is vertically mounted on the material sorting frame 21; a shaping plate 223, which is vertically movably connected to the material sorting frame 21, and a shaping channel 221 is formed between the shaping plate 223 and the shaping plate 1 222; wherein, a guide hole 211 is opened on the material sorting frame 21, and a guide rod 224 is passed through the guide hole 211, and the end of the guide rod 224 is connected to the side end of the shaping plate 223; a driving member 3 225 (a cylinder or a linear motor) is arranged on the material sorting frame 21, and the driving end of the driving member 3 225 is movably connected to the shaping plate 223, which is used to adjust the width of the shaping channel 221, and the rubber band is squeezed by the shaping plate 1 222 and the shaping plate 2 223 respectively to make the rubber band flat, thereby ensuring the beauty of the rubber band after sewing.

[0048] The driving pressure wheel assembly 24 includes: a rotating frame 241, a middle part of which is hinged on the material sorting frame 21; a roller 1 242, which is rotatably connected to the front end of the rotating frame 241; a roller 243, which is rotatably connected to the material sorting frame 21 and movably abuts against the roller 1 242; a driving member 4 244 (a rotating cylinder or a motor), which is arranged on the rotating frame 241 and is used to drive the roller 2 243 to rotate.

[0049] A connecting rod 245 is provided on the material sorting frame 21. A tension spring is connected between the connecting rod 245 and the rear end of the rotating frame 241 to enable the roller 1 242 to movably abut against the roller 2 243, thereby ensuring that when the roller 2 243 rotates, it can drive the rubber band to move.

[0050] Two limit members four 246 are provided on the rotating frame 241 to prevent the rubber band from detaching between the first roller 242 and the second roller 243.
