DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] <Implementation 1> like Figure 1-Figure 10 As shown, the packaging bag clamping and bag holding mechanism provided in the embodiment of the present application includes a base 100, a turntable 200, a clamping arm group 300, a clamping arm and a wind knife 900, wherein the base 100 is the supporting part of the packaging bag clamping and bag holding mechanism. The base 100 can play the role of supporting, reducing vibration and noise, protecting equipment, and improving work efficiency by reducing vibration displacement. The specific form of the base 100 can be various, such as a bottom plate structure, a frame structure, a column support structure, etc. In this embodiment, a column support structure can be selected as the base 100 of the packaging bag clamping and bag holding mechanism. The column support structure has the characteristics of good structural stability, good rigidity, and better support when the load is evenly distributed.

[0022] The turntable 200 is a rotatable platform in the packaging clamping and bag-holding mechanism. The turntable 200 is rotatably arranged on the upper surface of the base 100, and the turntable 200 can rotate relative to the base 100. A turntable 210 is also fixedly arranged on the top of the turntable 200, and the turntable 210 can rotate simultaneously with the turntable 200. In addition, the outer diameter of the turntable 210 is larger than the size of the top surface 630 of the turntable 200. A plurality of packaging stations 220 are arranged on the outer edge of the turntable 210, and the plurality of packaging stations 220 are distributed along the circumferential direction of the turntable 210. Each packaging station 220 is an installation position of the components responsible for clamping and bag-holding in the packaging clamping and bag-holding mechanism.

[0023] In this embodiment, each packaging station 220 at the outer edge of the turntable 210 is provided with a clamping arm set 300 and a clamping portion 500, and the number of the clamping arm sets 300 and the number of the clamping portions 500 are equal to the number of the packaging stations 220. In other words, the clamping arm sets 300 and the clamping portions 500 are in a one-to-one correspondence with the packaging stations 220.

[0024] The clamping arm group 300 is a component composed of two clamping arms 400. The clamping arm 400 is a rod-shaped structure with a certain length. A single clamping arm 400 has a free end and a fixed end in the length direction. The fixed end of the clamping arm 400 is fixedly arranged at the outer edge of the turntable 210 and is located in one of the packaging stations 220. In addition, the free end of the clamping arm 400 extends toward the outside of the turntable 210 along the radial direction of the turntable 210. That is, the two clamping arms 400 in each clamping arm group 300 are arranged at the outer edge of the turntable 210 and extend in the surrounding direction.

[0025] like Figure 5-Figure 8 As shown, the free end of the clamping arm 400 is provided with a clamping portion 500 for clamping, and the clamping portion 500 mainly plays the role of outputting clamping force and transmitting motion. Among them, the clamping portion 500 is composed of a wedge block 600, a fixed clamping piece 700 and a movable clamping plate 800. The wedge block 600 is a clamp made of metal, one of the surfaces of the wedge block 600 is an inclined surface 620, and the wedge block 600 is fixedly connected to the free end surface of the clamping arm 400 through the plane 610 on the opposite side of the inclined surface 620, and the wedge block 600 and the clamping arm 400 are also in a one-to-one correspondence. The wedge blocks 600 fixed at the free ends of the two clamping arms 400 are in a symmetrical relationship with each other, and the end thickness of the two inclined surfaces 620 of each wedge block 600 is greater than the end thickness close to the center position of the two clamping arms 400.

[0026] A fixing clip 700 is also provided beside the clamp arm 400. The fixing clip 700 serves as a fixing structure of the clamping portion 500 and mainly provides stability for the clamping portion 500. Specifically, the fixing clip 700 is provided on the outer surface of the clamp arm 400 and is located beside the wedge block 600. At the same time, the fixing clip 700 is also located on the thinner side of the wedge block 600. In each clamp arm set 300, two fixing clips 700 are located between two clamp arms 400.

[0027] Continue as Figure 5-Figure 8 As shown, the movable clamping plate 800 is arranged on the inclined surface 620 of the wedge block 600 by means of sliding connection. The movable clamping plate 800, as the movable structure of the clamping part 500, mainly plays the function of clamping and fixing the packaging bag to be clamped between the fixed clamping pieces 700. The end of the movable clamping plate 800 is also provided with a tilting portion 810, which extends toward the position of the fixed clamping piece 700, and a preset angle is also set between the tilting portion 810 and the end of the movable clamping plate 800. In addition, in this embodiment, the outer surface of the tilting portion 810 and the clamping surface of the fixed clamping piece 700 are parallel to each other.

[0028] In this embodiment, the movable clamp 800 can slide along the inclined surface 620 of the wedge block 600, and can simultaneously control the tilting portion 810 to move toward the position of the fixed clamp 700, so that the packaging bag to be clamped can be clamped between the fixed clamps 700 through the tilting portion 810, and finally the packaging bag can be clamped and fixed.

[0029] A wind knife 900 is also provided at the packaging station 220 of the turntable 210. Specifically, the wind knife 900 is fixedly provided on the upper surface of the turntable 210 through a bracket 920. The wind knife 900 is located above the clamping arm group 300 and the clamping part 500. The wind knife 900 is a gasket-type structure formed by a stainless steel gasket. The wind knife 900 has a V-shaped end face. A gap-shaped air outlet 940 is provided at a narrow portion of the V-shaped end face. The gap-shaped air outlet 940 faces between the fixed plate of the clamping part 500 and the tilting part 810 of the movable clamping plate 800.

[0030] like Fig. 9 and Fig.10 As shown, an air duct 950 is plugged into the air inlet 910 of the air knife 900, and the other end of the air duct 950 is connected to a blower 930, which is placed on the base 100 of the packaging clamping and bag-supporting mechanism and is located beside the turntable 200. In actual use, the blower 930 can be started to inject air into the air knife 900 through the air duct 950, so as to blow air toward the bag opening of the clamped packaging bag through the air knife 900, thereby realizing the function of blowing and supporting the bag.

[0031] Below is the accompanying drawing of the specification Figure 1-Figure 10 The working principle and usage process of the packaging clamping and bag-supporting mechanism are described.

[0032] In the related art, an automatic bag taking mechanism is generally used in conjunction with a packaging clamping and bag holding mechanism. The packaging bag to be filled is placed in the bag bin of the automatic bag taking mechanism, and the packaging bag is grabbed by a mechanical claw, and then the packaging bag is moved to the packaging clamping and bag holding mechanism for clamping and bag holding. The specific structure, working principle and working process of the automatic bag taking mechanism are all technical contents well known to those skilled in the art, so they are not described in detail in this embodiment.

[0033] The mechanical claw takes out the packaging bag in the bag bin of the automatic bag taking mechanism according to the pre-set program. At the same time, the turntable 200 drives the turntable 210 to rotate relative to the base 100, and controls the turntable 210 to rotate one of the packaging stations 220 to a position that matches the mechanical claw. Then, the mechanical claw moves the packaging bag taken out from the bag bin to the vicinity of the clamping arm group 300 of the packaging station 220.

[0034] In the initial state, the movable clamping plate 800 and the tilting portion 810 of the clamping portion 500 are both located beside the fixed clamping piece 700, so that the fixed clamping piece 700 can be completely exposed to the outside, so that the mechanical claw can move the packaging bag to the fixed clamping piece 700. Specifically, the mechanical claw will clamp the bag opening of the packaging bag and move the two side edges of the packaging bag in the width direction to the two fixed clamping pieces 700 of the clamping arm group 300.

[0035] like Figure 3 As shown, when the mechanical claw moves the two side edges of the packaging bag in the width direction to the position of the fixed clip 700, the movable clamping plate 800 will drive the tilting portion 810 to slide toward the position of the fixed clip 700. Since the movable clamping plate 800 slides along the inclined surface 620 of the wedge block 600, and at the same time, the tilting portion 810 and the clamping surface of the fixed clip 700 are parallel to each other. Therefore, the tilting portion 810 will gradually slide in the direction close to the clamping surface of the fixed clip 700 until the two side edges of the packaging bag in the width direction are clamped between the fixed clips 700, thereby achieving the clamping process of the packaging bag.

[0036] Continue as Figure 3 As shown, after the clamping part 500 clamps and fixes the packaging bag, the blower 930 can be started to blow air into the wind knife 900 through the air guide 950, and the wind knife 900 will blow air downward through the gap-shaped air outlet 940 on its V-shaped end face. Since the wind knife 900 is located directly above the clamping part 500, the wind knife 900 will blow air toward the opening of the packaging bag. As more and more air is blown into the packaging bag, the packaging bag will bulge outward, and its two sides will be pulled toward the middle during the bulging process, thereby achieving the bag support treatment for the packaging bag.

[0037] In the packaging clamping and bag-supporting mechanism provided in the embodiment of the present application, the clamping portion 500 of the packaging clamping and bag-supporting mechanism is in an open state in the initial state, that is, the tilting portion 810 of the movable clamping plate 800 is located beside the fixed clamping piece 700, and the packaging bag to be packaged can be transported to the packaging station 220 at the outer edge of the turntable 210 by the automatic bag-taking mechanism. In other words, the automatic bag-taking mechanism can transport the packaging bag to the side of the fixed clamping piece 700. Then, the movable clamping plate 800 is driven to make the tilting portion 810 move along the inclined surface 620 of the wedge block 600 until it moves to the position of the fixed clamping piece 700, and the packaging bag is fixed between the tilting portion 810 and the fixed clamping piece 700. Since the wind knife 900 is located directly above the fixed clamping piece 700 and the movable clamping plate 800, the wind knife 900 can play a role in supporting the bag by starting the fan to make the wind knife 900 blow air to the opening of the packaging bag. By adopting the above structural design, the purpose of supporting the bag can be achieved by sending air to the opening of the packaging bag, thereby solving the disadvantage that the suction cup cannot support and open the bag due to surface wear and other problems in the traditional mode.

[0038] In some embodiments, Figure 5-Figure 8 As shown, the top surface 630 and the bottom surface 640 of the movable clamping plate 800 are both provided with a lap plate 820, and the movable clamping plate 800 is slidably connected with the wedge block 600 through the lap plate 820. Specifically, the lap plate 820 of the movable clamping plate 800 is in sliding contact with the top surface 630 and the bottom surface 640 of the wedge block 600, respectively.

[0039] Preferably, a magnet sheet 830 is provided on one side of the lap plate 820, a first limit plate 650 is provided at the end of the wedge block 600 close to the fixed clip 700, and the wedge block 600 is provided with an electromagnet 660 through the first limit plate 650. In the present embodiment, the electromagnet 660 is a cylindrical electromagnet 660, that is, an electromagnet 660 formed by winding a current-carrying wire around a cylindrical iron core. Specifically, an alternating current is connected in the current-carrying wire, and the magnetic poles at both ends of the electromagnet 660 can be changed by connecting the alternating current, so that the electromagnet 660 generates an attraction or repulsion force on the magnet sheet 830, thereby realizing the control of the movable clamping plate 800 to move.

[0040] Based on the above embodiment, the top surface 630 of the wedge block 600 is also provided with a second limiting plate 670, and the second limiting plate 670 is located on the opposite side of the first limiting plate 650 in the length direction. The first limiting plate 650 and the second limiting plate 670 can limit the movable clamping plate 800 therebetween to prevent the movable clamping plate 800 from sliding out of the wedge block 600 through the lap plate 820, thereby playing a limiting function.

[0041] In some embodiments, a roller 710 is provided at the clamping surface of the fixed clip 700, and the roller 710 can rotate on a fixed axis above the vertical reference plane, and the movable clamping plate 800 can clamp the two side edges of the packaging bag on the roller 710 side of the fixed clip 700 through the tilting portion 810. When the wind knife 900 is used to blow air into the inside of the packaging bag through the bag opening, the packaging bag will pull the two side surfaces toward the middle while bulging, so under the action of the roller 710, the above process can be carried out more smoothly, thereby improving the bag-supporting efficiency of the packaging bag.

[0042] In some embodiments, the bracket 920 connecting the wind knife 900 and the turntable 210 is an inverted L-shaped bracket 920, the wind knife 900 is arranged at the top of the inverted L-shaped bracket 920, and the bottom of the inverted L-shaped bracket 920 is fixedly arranged on the turntable 210. In addition, the air duct 950 connected to the wind knife 900 and the blower 930 respectively is distributed along the shape of the inverted L-shaped bracket 920, and the air duct 950 is fixedly arranged on the side of the inverted L-shaped bracket 920 through the clamp 960.

[0043] Preferably, a hook 921 is also provided on the lower surface of the top of the bracket 920 connected to the wind knife 900. Correspondingly, a ring 970 is also provided on the top of the wind knife 900. The ring 970 is located beside the air inlet 910 of the wind knife 900. The wind knife 900 is mounted on the hook 921 through the ring 970, and the hook 921 and the ring 970 are fixedly connected to the bracket 920 by interference fit.

[0044] On the basis of the above embodiment, a clamping pin 922 is further provided outside the hook 921, and the clamping pin 922 can be inserted along the radial direction of the hook 921. In actual use, the clamping pin 922 can be inserted beside the hanging ring 970, and the clamping pin 922 and the hanging ring 970 are abutted, so as to prevent the hanging ring 970 from being separated from the hook 921, so as to improve the structural stability of the wind knife 900 and the bracket 920.

[0045] In some embodiments, the movable clamp 800 and the tilting portion 810 can be a hinged structure. By changing the preset angle of the tilting portion 810 relative to the movable clamp 800, the tilting portion 810 can clamp and fix packaging bags of different thicknesses with the fixed clip 700, thereby greatly improving the scope of use of the packaging clamping bag support mechanism.

[0046] <Implementation 2> An embodiment of the present application provides a bag-feeding packaging machine, which includes the packaging clamping and bag-supporting mechanism in Embodiment 1, and further includes an automatic bag-taking mechanism, a bag-filling mechanism, a sealing mechanism and a transportation mechanism; wherein the automatic bag-taking mechanism is used to take out the packaging bag and transport it to the packaging clamping and bag-supporting mechanism; the bag-filling mechanism is used to pour the material to be packaged into the packaging bag; the sealing mechanism is used to seal the packaging bag containing the material; and the transportation mechanism is used to carry out directional transportation of the sealed packaging bag.
