[0001] This utility model relates to a bag lifting and limiting device for a valve bag packaging machine, belonging to the field of valve bag packaging machines. Background Technology

[0002] Powder material valve packaging machine is an automated equipment that integrates filling and sealing. Currently, the filling port position of the filling mechanism of the packaging machine is fixed, while the bag size of the packaging bag is different. There will inevitably be shortcomings during filling. Specifically, the position of the packaging bag is not suitable, which leads to uneven pressure when filling powder materials, affecting the filling effect. In severe cases, it may be impossible to fill accurately into the packaging bag. Therefore, it is urgent to improve the structure of the packaging bag placement. Utility Model Content

[0003] The purpose of this invention is to provide a bag lifting and limiting device for a valve bag packaging machine, which can effectively solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] It includes a frame and a mounting frame disposed on the frame, wherein a pallet device and a lifting device for controlling the pallet device to be raised and lowered are disposed on the mounting frame;

[0006] The lifting device includes a first fixed plate and a second fixed plate located above the first fixed plate. A motor is provided at the lower end of the first fixed plate, and a screw is connected to the output end of the motor. A lifting plate is threaded onto the screw, and a limit hole is provided on the lifting plate. A limit rod is provided in the limit hole. The lower end of the limit rod is fixed to the first fixed plate, and the upper end of the limit rod is fixed to the second fixed plate. The upper end of the screw is rotatably mounted on the second fixed plate.

[0007] Furthermore: the pallet device is fixed to the lifting plate by a connecting plate. The pallet device includes a pallet and a flipping device for driving the pallet to flip. The flipping device includes a vertically arranged mounting plate. The pallet is hinged to the upper surface of the mounting plate, and a mounting groove is provided in the middle of the mounting plate. A flipping cylinder is provided in the mounting groove. The flipping cylinder is rotatably mounted on the mounting plate by a hinge seat. The piston end of the flipping cylinder is rotatably connected to the pallet by a connecting rod.

[0008] Furthermore, the mounting frame is also provided with a clamping device, which includes a side plate on the mounting frame, a mounting rod on the side plate, a clamping cylinder on the mounting rod, and a clamping plate at the output end of the clamping cylinder.

[0009] Furthermore, the clamping plate is provided with an extension plate by means of a sliding structure. The sliding structure includes a first sliding groove provided on the clamping plate, a second sliding groove provided on the extension plate, and a clamping bolt installed in the first sliding groove and the second sliding groove.

[0010] Furthermore, an inclined plate is provided on one side of the extension plate.

[0011] Furthermore, a stop plate is also provided between the side plates. The stop plate consists of a first vertical plate, a horizontal plate disposed on the upper surface of the first vertical plate, a second vertical plate disposed on the upper surface of the horizontal plate, and a folded plate disposed on the upper surface of the second vertical plate.

[0012] The beneficial effects are:

[0013] The filling port of this packaging machine is fixed, but the height of the packaging bag can be controlled by the lifting device, thereby adjusting the vertical position of the packaging bag. At the same time, the horizontal position of the packaging bag can be adjusted by the clamping device.

[0014] Meanwhile, an extension plate is installed in the clamping device. For a small number of large-sized packaging bags, the clamping plate cannot completely cover the packaging bag due to its excessive size, thus failing to clamp it properly. The extension plate solves this problem.

[0015] An inclined plate is provided on one side of the extension plate. Since the packaging bag is not a regular object with a certain shape, the two ends of the packaging bag will form an arc after filling. The inclined plate is mainly designed to match this arc. Attached Figure Description

[0029] See Figure 1-6 This is one embodiment of a bag lifting and limiting device for a valve bag packaging machine according to the present invention.

[0030] This device is mainly used for filling flour. In actual use, the packaging bag is placed on the pallet device 3, and then the filling mechanism on the frame 1 is operated to fill the packaging bag. The filling mechanism proposed in this application is a well-known technology in the field. However, since the packaging bags are of different sizes and the filling port position of the filling mechanism is fixed, it is necessary to adjust the position of the packaging bag. The adjustment is divided into vertical adjustment and horizontal adjustment.

[0031] See Figure 1 , Figure 2 The adjustment of the vertical position mainly relies on the lifting device 4;

[0032] The mounting frame 2 for mounting the lifting device 4 is fixed on the frame 1, and the lifting device 4 is mounted on the mounting frame 2. The lifting device 4 includes a first fixing plate 41 and a second fixing plate 42 located above the first fixing plate 41. A motor 43 is provided at the lower end of the first fixing plate 41. A screw 44 is connected to the output end of the motor 43. A lifting plate 45 is threadedly connected to the screw 44. The screw 44 is rotatably mounted on a threaded hole in the middle position of the lifting plate 45. Two limiting holes are provided on the lifting plate 45. The two limiting holes are symmetrically arranged on both sides of the threaded hole. A limiting rod 46 is provided in the limiting hole. The lower end of the limiting rod 46 is fixed on the first fixing plate 41, and the upper end of the limiting rod 46 is fixed on the second fixing plate 42. The upper end of the screw 44 is rotatably mounted on the second fixing plate 42.

[0033] When the lifting device 4 is in use, the motor 43 is started, which drives the screw 44 to rotate. The screw 44 then drives the lifting plate 45 to move. When the lifting plate 45 moves, it can move up and down due to the setting of the limit rod 46. This allows for adjustment of the up and down position of the pallet device 3. When the size of the packaging bag is small, the lifting plate 45 can be raised to align the opening of the packaging bag with the filling mechanism. When the size of the packaging bag is large, the lifting plate 45 can be lowered to ensure that the powder is accurately filled into the bag.

[0034] Simultaneously, after filling is completed, the packaging bag needs to be sealed. The specific sealing structure is also set on the frame 1, which is not described in this application document, but integrating the sealing equipment on the frame 1 is a well-known technology in the art. After sealing, the packaged bag also needs to be removed from the pallet device 3. This device is equipped with an automated structure that can automatically remove the packaging bag located on the pallet 31. The specific structure is as follows:

[0035] See Figure 3 , Figure 5The pallet device 3 is fixed to the lifting plate 45 by the connecting plate 5. The pallet device 3 includes a pallet 31 and a flipping device 32 for driving the pallet 31 to flip. The flipping device 32 includes a vertically arranged mounting plate 321. The pallet 31 is hinged to the upper end face of the mounting plate 321, and a mounting groove 322 is provided in the middle of the mounting plate 321. A flipping cylinder 323 is provided in the mounting groove 322. The flipping cylinder 323 is rotatably mounted on the mounting plate 321 by the hinge seat 324. The piston end of the flipping cylinder 323 is rotatably connected to the pallet 31 by a connecting rod 325.

[0036] After sealing is completed, the flipping cylinder 323 operates, and the piston pushes the connecting rod 325. The connecting rod 325 then drives the pallet 31, which is hinged to the mounting plate 321, to rotate. At this time, the pallet 31 tilts, and the packaging bag on the pallet 31 slides down in the direction of the tilt, completing the automatic unloading of the packaging bag. In this device, the mounting plate 321 is mainly used to install the structure that realizes the flipping. At the same time, in order for the flipping cylinder 323 to work normally, the flipping cylinder 323 is rotatably mounted on the mounting plate 321 through the hinge seat 324. In addition, in order to achieve a high degree of equipment integration, a mounting groove 322 is set in the middle of the mounting plate 321. The purpose is to provide installation space for the flipping cylinder 323. At the same time, the installation position of the flipping cylinder 323 can be used to increase the force transmission and realize the flipping of the pallet 31.

[0037] The left and right position adjustment in this device mainly relies on the clamping device 6, the specific structure of which is as follows:

[0038] See Figure 3 , Figure 4 The mounting frame 2 is also provided with a clamping device 6, which includes a side plate 61 on the mounting frame 2, a mounting rod 62 on the side plate 61, a clamping cylinder 63 on the mounting rod 62, and a clamping plate 64 at the output end of the clamping cylinder 63.

[0039] Two clamping cylinders 63 are used to control the relative movement of two clamping plates 64, thereby clamping the packaging bag and adjusting its left and right position. When clamping the packaging bag, if the bag is not in the center of the pallet 31, the force exerted by the different clamping plates 64 will vary, thus correcting the bag to be in the center of the pallet 31. The side plate 61 extends outwards to provide installation space for the clamping cylinders 63, as the clamping cylinders 63 need to push the clamping plates 64. 4. The clamping plate 64 needs to clamp a packaging bag of a certain length, so the clamping cylinder 63 needs to be located in the middle of the packaging bag. The side plate 61 is used to fix the position of the clamping cylinder 63. At the same time, a mounting rod 62 is provided on the side plate 61. The main function of the mounting rod 62 is to bear the reaction force from the clamping cylinder 63 and prevent the entire side plate 61 from bending due to the reaction force. The mounting rod 62 can absorb part of the reaction force, and even if the mounting rod 62 bends, the replacement cost is much lower than that of the side plate 61.

[0040] An extension plate 65 is provided on the clamping plate 64 via a sliding structure 66. The sliding structure 66 includes a first sliding groove 661 on the clamping plate 64, a second sliding groove 662 on the extension plate 65, and a clamping bolt 663 installed in the first sliding groove 661 and the second sliding groove 662.

[0041] The main function of the extension plate 65 in this device is to facilitate clamping large-sized packaging bags. Most flour packaging bags do not use the extension plate 65, but there are still a small number of large-sized packaging bags that are too large for the clamping plate 64 to completely cover, thus making it impossible to clamp them well. The extension plate 65 solves this problem.

[0042] Meanwhile, in order for the clamping plate 64 and the extension plate 65 to perfectly fit the size of the packaging bag, the sliding structure 66 can be used to adjust the length of the extension plate 65. This can be achieved by tightening or loosening the clamping bolt 663.

[0043] An inclined plate 67 is provided on one side of the extension plate 65.

[0044] Since the packaging bag is not a regular object with a certain shape, the two ends of the packaging bag will form an arc after filling. The inclined plate 67 is mainly set to match this arc.

[0045] See Figure 6 A stop plate 7 is also provided between the side plates 61. The stop plate 7 is composed of a first vertical plate 71, a horizontal plate 72 provided on the upper end surface of the first vertical plate 71, a second vertical plate 73 provided on the upper end surface of the horizontal plate 72, and a folding plate 74 provided on the upper end of the second vertical plate 73.

[0046] The abutment 7 of this device is mainly for providing better force to the ends of the packaging bag.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
