Description

Technical field:

[0001] The present invention relates to the technical field of packaging bag processing equipment, in particular to a folding device for a single cup machine. Background technology:

[0002] The folding device is a common mechanism in the packaging paper bag production line, which is mainly used to fold the paper bag.

[0003] With the improvement of people's living standards and the strengthening of environmental awareness, the market is now in urgent need of a large number of small-sized paper bags with special specifications. The original paper bag machine is mainly used to weave paper bags of regular sizes. It generally uses a double template fixing beam, and the template fixing beam is the same length as the template to facilitate the fixing of the upper and lower templates. The front and rear six sets of rubbing wheels are of equal size. For paper bags with similar width and side width, the last two rubbing wheels will interfere with the template fixing frame. This structure is obviously unsuitable for weaving, so the folding device needs to be improved. Summary of the invention:

[0004] In response to the above problems, the present invention proposes a folding device for a single cup machine with good folding effect, stable wiping, good effect, high structural reliability, smooth transmission, convenient adjustment and high degree of automation.

[0005] The present invention is realized through the following technical scheme: a single cup machine folding device comprises a frame component and a template beam component, a rubbing wheel component, a rubbing wheel adjusting component and a thumb buckle component arranged on the frame component.

[0006] Furthermore, the frame component includes two vertical and parallel columns, two horizontal and parallel beams, a circular support, an upper support, and a fixed pin shaft. One end of the two beams is respectively connected to the two columns, the circular support is arranged between the two columns, the upper support is connected between the two columns through the fixed pin shaft and is located at the upper end of the columns, and the following guide plate bracket is connected to the upper support.

[0007] Furthermore, the frame component also includes two fixing plates, and the fixing plates are symmetrically connected to the columns on both sides.

[0008] The template beam component is used to cooperate with the following rubbing wheel component to complete the folding of paper bags, including a guide plate bracket, a template fixing frame, an upper template, and a lower template. The guide plate bracket is fixedly connected to the upper support of the frame component, and the template fixing frame is fixedly connected to the lower end of the guide plate bracket. The upper template and the lower template are respectively connected to the upper end face and the lower end face of the template fixing frame.

[0009] In order to improve the connection strength between the upper template and the lower template, the template beam component also includes a template pad, which is arranged at one end of the upper template and the lower template away from the thumb buckle component and connects the upper template and the lower template.

[0010] In order to fine-tune the position of the template beam component, the frame component also includes an upper support adjustment component, which can drive the upper support to swing around the fixed pin shaft, thereby driving the guide plate bracket to swing, and then fine-tune the position of the entire template beam component.

[0011] Furthermore, in order to make the structure more compact, preferably, the upper support adjustment assembly includes an adjustment block and a screw, the screw is screwed into the adjustment block, one end of which abuts against the upper support, and the upper support can be driven to swing around the fixed pin by screwing in or out the screw.

[0012] The rubbing wheel component is used to fold the paper bag, including two guide wheel fixing plates symmetrically arranged on both sides of the template fixing frame and several groups of rubbing wheel assemblies arranged on the guide wheel fixing plates. The rubbing wheel assembly includes a rubbing wheel, a guide wheel bushing, and a guide wheel shaft. The guide wheel shaft is connected to the guide wheel fixing plate. The guide wheel bushing is arranged on the upper end of the guide wheel shaft through a bearing sleeve and can rotate freely. The rubbing wheel is connected to the guide wheel bushing and can rotate with the guide wheel bushing. The rubbing wheels are symmetrically distributed on both sides of the template fixing frame and are located between the upper template and the lower template. The rubbing wheels on the two guide wheel fixing plates correspond to each other one by one.

[0013] In order to improve the folding effect, 6 groups of rubbing wheel assemblies are evenly distributed on each guide wheel fixing plate. Since the surface width and side width of the paper bag are almost the same, the rubbing wheels in the rubbing wheel assembly are gradually increasing in diameter and gradually becoming thinner in thickness in the direction away from the thumb buckle component. In order to avoid the rubbing wheels, the width of the template fixing frame gradually becomes smaller, that is, the two side surfaces of the template fixing frame are inclined.

[0014] The rubbing wheel adjustment component is used to adjust the gap between the rubbing wheels on both sides of the template fixing frame to adjust the rubbing depth, including an adjusting plate assembly and a screw. One end of the screw is connected to the guide wheel fixing plate through a fisheye joint, and the other end is connected to an adjusting handwheel. The screw is screwed into the adjusting plate assembly and can be rotated in and out of the adjusting plate assembly to drive the guide wheel fixing plate close to or away from the template fixing frame, thereby reducing or increasing the gap between the rubbing wheels on the guide wheel fixing plates on both sides to adjust the rubbing depth so as to obtain a paper bag with the required side width.

[0015] Furthermore, the adjustment plate assembly includes a vertical plate, a horizontal plate, an adjustment plate, and a sliding nut.

[0016] In order to adjust the height of the vertical plate so that the wiping wheel is always located between the upper template and the lower template to facilitate paper folding, a waist-shaped vertical plate mounting hole is opened on the vertical plate, and the vertical plate is connected to the crossbeam in an adjustable height through the vertical plate mounting hole, and the cross plate is connected to the upper end of the vertical plate.

[0017] In order to adjust the position of the adjustment plate relative to the template fixing frame, a waist-shaped adjustment plate mounting hole is opened on the adjustment plate. The adjustment plate is horizontally adjustable connected to the cross plate through the adjustment plate mounting hole and the sliding nut. The adjustment plate has a screw connection part, and the screw is screwed into the screw connection part.

[0018] In order to make the adjustment smoother, preferably, each guide wheel fixing plate is provided with two sets of the rubbing wheel adjustment components.

[0019] The thumb button component is used for cutting paper, and includes a rotating shaft, a circular knife seat, a circular knife, and a rotating shaft driving component. The rotating shaft is horizontally arranged on the frame component and can rotate freely. Specifically, the two ends of the rotating shaft are respectively arranged in the fixed plates on both sides through bearings. The rotating shaft driving component is connected to the rotating shaft and can drive the rotating shaft to rotate. The circular knife is connected to the rotating shaft through the circular knife seat and can rotate with the rotating shaft.

[0020] In order to avoid the circular knife, a square hole is opened on the lower template, and the square hole corresponds to the position of the circular knife.

[0021] In order to facilitate the control and adjustment of the paper cutting speed and make the structure more compact, as a preferred embodiment, the rotating shaft drive component includes a first synchronous pulley, a second synchronous pulley, a synchronous belt, a motor base, and a servo motor reducer. The servo motor reducer is connected to the fixed plate on one side through the motor base. The first synchronous pulley is mounted on the rotating shaft and can drive the rotating shaft to rotate. The second synchronous pulley is connected to the output shaft of the servo motor reducer. The synchronous belt is mounted on the first and second synchronous pulleys and can rotate with the rotation of the second synchronous pulley, thereby driving the first synchronous pulley to rotate, and then driving the rotating shaft and the circular knife on the rotating shaft to rotate. Other types of rotating shaft drive components can also be designed according to actual conditions.

[0022] The beneficial effects of the present invention are as follows: the folding device of the single-cup machine performs folding by designing 6 groups of rubbing wheels with gradually increasing outer diameters and gradually decreasing thicknesses, and cooperates with a template fixing frame with gradually decreasing width to improve the folding effect; by designing a horizontal adjustment component for the rubbing wheel, the rubbing depth can be adjusted to obtain a paper bag with a required side width, which greatly improves the flexibility and versatility of the folding device; by designing a height adjustment device for the rubbing wheel, it is ensured that the rubbing wheel is always located between the upper template and the lower template, thereby improving the convenience and reliability of paper folding; in addition, the folding device of the single-cup machine has a compact and reliable structure, high stability, and a high degree of automation, and is suitable for small-sized paper bags of special specifications.

The upper support block 14 can be driven to swing around the fixed pin shaft 15 by screwing in or out the screw 162, thereby driving the guide plate bracket 21 to swing, and then fine-tuning the position of the template beam component 2.

[0039] like Figure 8-10As shown, the rubbing wheel component 3 includes two guide wheel fixing plates 31 symmetrically arranged on both sides of the template fixing frame 22 and 6 groups of rubbing wheel assemblies 32 arranged on each of the guide wheel fixing plates 31. The rubbing wheel assembly 32 includes a rubbing wheel 321, a guide wheel sleeve 322, and a guide wheel shaft 323. The guide wheel shaft 323 is connected to the guide wheel fixing plate 31.

[0040] The rubbing wheels 321 are symmetrically distributed on both sides of the template fixing frame 22 and are located between the upper template 23 and the lower template 24. The rubbing wheels 321 on the two guide wheel fixing plates 31 correspond to each other one by one. In the direction away from the thumb buckle component 5, the rubbing wheels 321 are gradually larger in diameter and gradually thinner in thickness. Figure 7 As shown, the width of the template fixing frame 22 gradually decreases.

[0041] like Figure 11-12 As shown, the rubbing wheel adjustment component 4 is used to adjust the rubbing depth, including an adjustment plate assembly 41 and a screw 42.
