Compared with the prior art, the beneficial effects of the document are: simple structure, convenient control, and meeting the requirements of automatic control.

[0004] However, the gripper of the document can only play a simple role of clamping the packaging bag. The position of the gripper is fixed and cannot adapt to packaging bags of different specifications. It also cannot better open the packaging bags that are difficult to open, and the reliability of clamping and opening the packaging bag cannot be ensured. Summary of the invention

[0005] The present invention provides a swing clamping bag feeding type packaging machine, which is equipped with a clamping bag opening device so that the position of the clamping device can be adjusted, thereby being able to adapt to packaging bags of different specifications and being able to pre-open the packaging bags, thereby facilitating subsequent packaging of materials and having good reliability.

[0006] To achieve the above-mentioned purpose, a swing clamping bag-feeding packaging machine includes a frame, a turntable is provided at the center of the frame, and more than one clamping mechanism is provided on the turntable. On the frame, a bag-feeding device for conveying the packaging bag to the clamping mechanism, an opening device for opening the packaging bag, a feeding device for conveying materials into the packaging bag, and a bag sealing device for sealing the packaging bag are arranged in a ring in sequence around the turntable and corresponding to the clamping mechanism; the turntable drives the clamping mechanism to pass through the opening device, the feeding device and the bag sealing device in sequence.

[0007] The clamping mechanism includes a first hand clamping device, a second hand clamping device, a bag clamping and opening device, and a hand clamping and releasing device. The first hand clamping device and the second hand clamping device are arranged below the turntable through the bag clamping and opening device, and the bag clamping and opening device drives the first hand clamping device and the second hand clamping device to move closer to and away from each other. A hand clamping and releasing device corresponding to the hand clamping device is provided below the turntable; the first hand clamping device and the second hand clamping device clamp both sides of the packaging bag respectively; when the bag clamping and opening device drives the first hand clamping device and the second hand clamping device to move closer to each other, the opening of the packaging bag is opened.

[0008] The first gripper device comprises a first gripper driving cam, a first gripper fixing plate, and a first gripper movable plate. The gripper releasing device drives the first gripper driving cam to rotate so that the first gripper fixing plate and the first gripper movable plate are arranged away from each other. When the first gripper fixing plate and the first gripper movable plate are close to each other, the first gripper driving cam returns to the dead point position.

[0009] The above structure is provided with a turntable on the frame, and a clamping mechanism is provided on the turntable, thereby the packaging bag is conveyed to the clamping mechanism by the bag feeding device, and then the packaging bag is clamped and fixed by the clamping mechanism, and the opening of the packaging bag is opened when the first clamping device and the second clamping device are driven to approach each other by the clamping bag opening device, thereby the packaging bag is pre-opened, so as to facilitate the subsequent packaging of the material, and when the opening of the packaging bag is opened, the packaging bag can be fully opened by the opening device, thereby ensuring that the feeding device can better convey the material into the packaging bag, and when the material conveying is completed, the packaging bag can be sealed by the bag sealing device, thereby the packaging process of the material can be automated, so that the packaging efficiency is high, and the first clamping driving cam is driven to rotate by the clamping and releasing device so that the first clamping fixed plate and the first clamping movable plate are separated from each other to realize opening, and then when the first clamping fixed plate and the first clamping movable plate are arranged in parallel, the first clamping driving cam returns to the dead point position, and the first clamping driving cam will not move, thereby realizing the clamping of the packaging bag, so that the reliability of clamping and releasing is good.

[0010] Furthermore, the first gripper device also includes a first gripper mounting plate, a first gripper driving rod, a first gripper connecting block and a first gripper reset spring, the first gripper mounting plate being arranged on the clamping and bag opening device, the first gripper driving cam being swingably arranged on one end of the first gripper mounting plate through the first gripper cam shaft, one end of the first gripper driving rod being hinged on one end of the first gripper driving cam, one end of the first gripper connecting block being hinged to the other end of the first gripper driving rod, and the other end of the first gripper connecting block being hinged to the other end of the first gripper mounting plate, and a first gripper fixing plate being also provided at the other end of the first gripper mounting plate, the first gripper movable plate being arranged on the first gripper connecting block, a packaging bag being clamped between the first gripper movable plate and the first gripper fixing plate, one end of the first gripper reset spring being arranged on the first gripper mounting plate, the other end of the first gripper reset spring being connected to one end of the first gripper driving cam, a gripper driving pulley being provided on the other end of the first gripper driving cam, the gripper driving pulley being in contact with and connected to the gripper releasing device, and the second gripper device has the same structure as the first gripper device.

[0011] The above arrangement, by setting the first gripper driving cam, the position between the hinge point of the first gripper driving cam and the first gripper driving rod, the intersection point of the first gripper driving rod and the first gripper connecting block and the intersection point of the first gripper connecting block and the other end of the first gripper mounting plate is located at the dead point position of the cam mechanism, thereby the first gripper driving rod and the first gripper connecting block are stuck at the dead point position of the cam mechanism, so that the first gripper driving rod and the first gripper connecting block cannot move without the influence of external force, and further the connection between the first gripper movable plate and the first gripper fixed plate will not loosen, thereby clamping the packaging bag.

[0012] Furthermore, the gripper releasing device includes a gripper releasing mounting frame, a gripper releasing cylinder, a gripper releasing connecting plate and a gripper releasing driving plate. The gripper releasing mounting frame is arranged below the turntable, and a gripper releasing cylinder is arranged on the gripper releasing mounting frame. The gripper releasing connecting plate is arranged on the piston rod of the gripper releasing cylinder. The gripper releasing driving plate is arranged on the gripper releasing connecting plate. The front end of the gripper releasing driving plate is provided with an inclined surface which is inclined to both sides and extends to the rear end of the gripper releasing driving plate. The gripper driving pulleys of the first gripper device and the second gripper device are respectively in contact and connected with the inclined surfaces on both sides of the gripper releasing driving plate.

[0013] The gripper release cylinder drives the gripper release driving plate to move forward and contact and connect with the gripper driving pulley. When the gripper release driving plate continues to move forward, it drives the gripper driving pulley to swing outward. Since the first gripper driving cam is set on the first gripper mounting plate through the first gripper cam shaft swing, when the other end of the first gripper driving cam swings outward, one end of the first gripper driving cam swings in the opposite direction, thereby driving the first gripper driving rod to swing along. When the first gripper driving rod swings, it drives the first gripper connecting block to swing. When one end of the first gripper driving cam swings, it also drives the first gripper reset spring to stretch. Therefore, the first gripper movable plate can be moved away from the first gripper fixed plate, thereby realizing the release of the first gripper device. The packaging bag is transported to the position of the clamping mechanism through the bag feeding device so that the side of the packaging bag is located between the first gripper movable plate and the first gripper fixed plate. When the gripper is released When the cylinder drives the gripper to release the driving plate and move backward, the rebound force of the first gripper reset spring drives one end of the first gripper driving cam to swing and reset, so that the first gripper driving rod drives the first gripper movable plate to approach the first gripper fixed plate and clamp the side of the packaging bag. When the first gripper reset spring resets the first gripper driving cam, the position between the hinge point of the first gripper driving cam and the first gripper driving rod, the intersection point of the first gripper driving rod and the first gripper connecting block, and the intersection point of the first gripper connecting block and the other end of the first gripper mounting plate are located at the dead point position of the cam mechanism. As a result, the first gripper driving rod and the first gripper connecting block are stuck at the dead point position of the cam mechanism, so that the first gripper driving rod and the first gripper connecting block cannot move without the influence of external force, and then the connection between the first gripper movable plate and the first gripper fixed plate will not loosen, thereby clamping the packaging bag.

[0014] The above arrangement drives the gripper release drive plate to move forward through the gripper release cylinder and contact and connect with the gripper drive pulley. When the gripper release drive plate continues to move forward, it drives the gripper drive pulley to swing outward, thereby driving the first gripper drive cam to swing, thereby destroying the dead point of the cam mechanism, thereby loosening the first gripper movable plate and the first gripper fixed plate, thereby facilitating the clamping and loosening of the packaging bag.

[0015] Furthermore, the clamping and opening bag device includes a bag opening motor, a first bag opening screw rod, a second bag opening screw rod, a first bag opening slider and a second bag opening slider, one end of the first bag opening screw rod is arranged on the turntable through the first bag opening screw rod bearing seat, one end of the second bag opening screw rod is arranged on the turntable through the second bag opening screw rod bearing seat, the other ends of the first bag opening screw rod and the second bag opening screw rod are connected to each other, a bag opening motor is provided on the turntable at one end of the first bag opening screw rod, a driving shaft of the bag opening motor is connected to the first bag opening screw rod, a first bag opening slider is provided on the first bag opening screw rod, and a second bag opening slider is provided on the second bag opening screw rod, and a bag opening through hole is provided on the turntable below the first bag opening screw rod and the second bag opening screw rod, the first bag opening slider extends through the bag opening through hole to the bottom of the turntable and is connected to the first hand clamping device, the second bag opening slider extends through the bag opening through hole to the bottom of the turntable and is connected to the second hand clamping device, and the thread spiral directions of the first bag opening screw rod and the second bag opening screw rod are opposite.

[0016] According to the above arrangement, the first bag opening screw rod is driven to rotate by the bag opening motor. Since the screw threads of the first bag opening screw rod and the second bag opening screw rod have opposite directions, the first bag opening slider and the second bag opening slider can be driven to approach or move away from each other, thereby adjusting the distance between the first hand clamping device and the second hand clamping device according to the specifications of the packaging bag. At the same time, the first hand clamping device and the second hand clamping device can also be controlled to approach each other to pre-open the packaging bag.

[0017] Furthermore, the bag feeding device includes a bag feeding bracket, a bag feeding swing motor, a bag feeding swing base plate, a bag feeding adjusting cylinder, a bag feeding clamping component and a bag feeding clamping plate.

The stretching lifting module drives the stretching base to move downward so that the first stretching plate and the second stretching plate extend into the opening of the packaging bag. The stretching cylinder extends the retracted piston rod so that the first stretching connecting rod and the second stretching connecting rod swing with the hinge point of the stretching mounting seat as the fulcrum so that the first stretching plate and the second stretching plate move away from each other to stretch the opening of the packaging bag; the adsorption component is located at the front and rear end of the packaging bag, and when the stretching component stretches the opening of the packaging bag, the adsorption component respectively adsorbs the front and rear end of the packaging bag and moves them away from each other so that the opening of the packaging bag is fully opened.

[0020] With the above arrangement, the opening of the packaging bag is opened by the opening component, and then the front and rear ends of the packaging bag are adsorbed and moved away from each other by the adsorption component so that the opening of the packaging bag is completely opened, thereby facilitating subsequent material transportation.

The first adsorption cylinder and the second adsorption cylinder respectively drive the first adsorption connecting rod and the second adsorption connecting rod to move away from each other so that the opening of the packaging bag is fully opened.

DETAILED DESCRIPTION

[0041] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1-11 As shown, a swing clamping bag-feeding packaging machine comprises a frame 1, a turntable 10 is provided at the center of the frame 1, one or more clamping mechanisms 2 are provided on the turntable 10, and a bag-feeding device 3 for conveying a packaging bag (not shown in the figure) to the clamping mechanism 2, an opening device 4 for opening the packaging bag, a feeding device 5 for conveying materials into the packaging bag, and a bag-sealing device 6 for sealing the packaging bag are arranged in a circular manner in sequence around the turntable 10 on the frame 1 and corresponding to the clamping mechanism 2; the turntable 10 drives the clamping mechanism 2 to pass through the opening device 4, the feeding device 5 and the bag-sealing device 6 in sequence from the position of the bag-feeding device 3.

[0043] like Figure 2 and Figure 3 As shown, the clamping mechanism 2 includes a first hand clamping device 21, a second hand clamping device 22, a clamping and bag opening device 23 and a clamping and releasing device 24. The first hand clamping device 21 and the second hand clamping device 22 are arranged below the turntable 10 through the clamping and bag opening device 23, and the clamping and bag opening device 23 drives the first hand clamping device 21 and the second hand clamping device 22 to move closer to or away from each other. A clamping and releasing device 24 corresponding to the first hand clamping device 21 and the second hand clamping device 22 is provided below the turntable 10; the first hand clamping device 21 and the second hand clamping device 22 clamp both sides of the packaging bag respectively; when the clamping and bag opening device 23 drives the first hand clamping device 21 and the second hand clamping device 22 to move closer to each other, the opening of the packaging bag is opened.

[0044] The gripping and releasing device is located between the first gripping device 21 and the second gripping device 22, and the gripping and releasing device drives the first gripping device and the second gripping device to release the gripping of the packaging bag.

[0045] like Figure 4 As shown, the first gripper device 21 includes a first gripper mounting plate 211, a first gripper driving cam 212, a first gripper driving rod 213, a first gripper connecting block 214, a first gripper fixing plate 215, a first gripper movable plate 216 and a first gripper reset spring 217. The first gripper mounting plate 211 is arranged on the bag clamping and opening device 23. The first gripper driving cam 212 is swingably arranged on one end of the first gripper mounting plate 211 through a first gripper cam shaft 218. One end of the first gripper driving rod 213 is hinged to one end of the first gripper driving cam 212. One end of the first gripper connecting block 214 is hinged to the other end of the first gripper driving rod 213. The other end of the first gripper connecting block 214 is hinged to On the other end of the first gripper mounting plate 211, a first gripper fixing plate 215 is also provided on the other end of the first gripper mounting plate 211, the first gripper movable plate 216 is arranged on the first gripper connecting block 214, a packaging bag is clamped between the first gripper movable plate 216 and the first gripper fixing plate 215, one end of the first gripper reset spring 217 is arranged on the first gripper mounting plate 211, the other end of the first gripper reset spring 217 is connected to one end of the first gripper driving cam 212, a gripper driving pulley 219 is provided on the other end of the first gripper driving cam 212, the gripper driving pulley 219 is in contact and connected with the gripper releasing device 24, and the second gripper device 22 has the same structure as the first gripper device 21.

[0046] like Figure 6As shown, the gripper releasing device 24 includes a gripper releasing mounting frame 241, a gripper releasing cylinder 242, a gripper releasing connecting plate 243 and a gripper releasing driving plate 244. The gripper releasing mounting frame 241 is arranged below the turntable 10, and a gripper releasing cylinder 242 is arranged on the gripper releasing mounting frame 241. The gripper releasing connecting plate 243 is arranged on the piston rod of the gripper releasing cylinder 242. The gripper releasing driving plate 244 is arranged on the gripper releasing connecting plate 243. The front end of the gripper releasing driving plate 244 is provided with an inclined surface which is inclined to both sides and extends to the rear end of the gripper releasing driving plate 244. The gripper driving pulleys 219 of the first gripper device 21 and the second gripper device 22 are respectively in contact and connected with the inclined surfaces on both sides of the gripper releasing driving plate 244.

[0047] The gripper release cylinder 242 drives the gripper release drive plate 244 to move forward and contact and connect with the gripper drive pulley 219. When the gripper release drive plate 244 continues to move forward, it drives the gripper drive pulley 219 to swing outward (such as Figure 5 As shown in the direction of the middle arrow α, since the first gripper driving cam 212 is swingably arranged on the first gripper mounting plate 211 through the first gripper cam shaft 218, when the other end of the first gripper driving cam 212 swings outward, one end of the first gripper driving cam 212 swings in the opposite direction (as shown in the direction of the middle arrow α). Figure 5 As shown in the direction of the arrow β in the middle), the first gripper driving rod 213 is driven to follow the swing (as shown in the direction of the arrow β in the middle). Figure 5 As shown in the direction of the arrow γ in the middle, the first gripper driving rod 213 swings while driving the first gripper connecting block 214 to swing (as shown in the direction of the arrow γ in the middle). Figure 5 As shown in the direction of the arrow δ in the middle, while one end of the first gripper driving cam 212 swings, it also drives the first gripper reset spring 217 to stretch, thereby moving the first gripper movable plate 216 away from the first gripper fixed plate 215 (as shown in the direction of the arrow δ in the middle). Figure 5215), and the first gripper device 21 is released. The packaging bag is transported to the position of the clamping mechanism 2 through the bag feeding device 3 so that the side of the packaging bag is located between the first gripper movable plate 216 and the first gripper fixed plate 215. When the gripper release cylinder 242 drives the gripper release drive plate 244 to move backward so that the gripper release drive plate 244 is not in contact with the gripper drive pulley 219, the rebound force of the first gripper reset spring 217 drives one end of the first gripper drive cam 212 to swing and reset, so that the first gripper drive rod 213 drives the first gripper movable plate 216 to approach the first gripper fixed plate 215 and clamp the side of the packaging bag. When the first gripper reset spring 217 resets the first gripper drive cam 212, the first gripper drive cam 212 and the first gripper drive cam 212 are in contact. The position between the hinge point of the first gripper drive rod 213, the intersection point of the first gripper drive rod 213 and the first gripper connecting block 214, and the intersection point of the first gripper connecting block 214 and the other end of the first gripper mounting plate 211 is located at the dead point of the cam mechanism. The dead point of the cam mechanism is the position when the cam mechanism no longer rotates when the first gripper fixed plate 215 and the first gripper movable plate 216 are parallel under the action of the first gripper reset spring 217. As a result, the first gripper drive rod 213 and the first gripper connecting block 214 are stuck at the dead point of the cam mechanism, so that the first gripper drive rod 213 and the first gripper connecting block 214 cannot move without the influence of external force, and further, the connection between the first gripper movable plate 216 and the first gripper fixed plate 215 will not loosen, thereby clamping the packaging bag. The gripper release cylinder 242 drives the gripper release drive plate 244 to move forward and contact and connect with the gripper drive pulley 219. When the gripper release drive plate 244 continues to move forward, it drives the gripper drive pulley 219 to swing outward, thereby driving the first gripper drive cam 212 to swing, thereby destroying the dead point of the cam mechanism, thereby loosening the first gripper movable plate 216 and the first gripper fixed plate 215, thereby facilitating the clamping and loosening of the packaging bag.
