Abstract
Description
Technical Field
[0001] This utility model relates to a bag flipping device, belonging to the technical field of infusion bag conveying equipment. Background Technology
[0002] After sterilization, the infusion pouches need to be automatically leak-tested using a light inspection machine. However, the light inspection machine requires the pouches to be placed with the reverse side facing up, which is the opposite of the sterilization process's requirement of the front side facing up. To solve the problem of the mismatch in the orientation of the infusion pouches in the two processes, the current practice is to manually turn and arrange the bags before light inspection. However, manual bag turning is limited by manpower and is difficult to operate efficiently and stably, which not only increases labor costs but also seriously affects the overall efficiency of the production line. Utility Model Content

[0004] The present invention relates to a bag flipping device, comprising: a flipping cylinder for flipping infusion soft packs is clamped on a tray by a clamping device.
[0005] The side of the tray is hinged with a support arm and a telescopic adjustment rod. The other end of the adjustment rod is hinged to the support frame, and the adjustment rod can adjust the tilt angle of the tray.
[0006] The inverting tube includes a slide tube with a guide block inserted inside. A spiral groove runs through the guide block, and the spiral groove and the inner wall of the slide tube form an inverting cavity, through which the infusion pack can spirally pass. A flared guide cover is provided at the inlet of the slide tube.
[0007] Furthermore, one end of the guide block is provided with a connecting part, which is close to the inlet of the slide; a connecting roller is hinged on the connecting part, and one side of the connecting part smoothly transitions with the spiral groove of the guide block.
[0008] Furthermore, the adjusting rod includes an adjusting nut, on which are connected a first screw and a second screw with opposite thread directions. One end of the first screw is hinged to the support frame, and one end of the second screw is hinged to the support plate.
[0009] Furthermore, the clamping device includes: a gasket disposed on the tray, and a clamp fitted onto the slide; the slide is fitted onto the gasket, and the clamp can be fixedly connected to the tray.
[0010] Furthermore, the tray is perforated.
[0011] Furthermore, both the support frame and the support arm are fixedly connected to the overturned conveyor belt.
[0012] The inlet of the slide drum is connected to the output end of the conveyor belt before it is flipped via a connecting part.
[0013] The advantages of this utility model compared with the prior art are:
[0014] Batch of infusion soft packs can pass through the turning cylinder continuously and stably, and automatically turn over under the constraint of the turning chamber, avoiding the disadvantages of manual bag turning, and greatly improving the bag turning efficiency of infusion soft packs.

[0029] like Figures 1-4 As shown, this embodiment is achieved through the following technical solution: the bag flipping device is connected between the conveyor belt 8 before flipping and the conveyor belt 9 after flipping.
[0030] A bag flipping device includes a tray 2, on which a flipping cylinder 6 for flipping infusion soft packs is clamped by a clamping device.
[0031] The side of the tray 2 is hinged with a support arm 3 and a telescopic adjustment rod 7. The other end of the adjustment rod 7 is hinged to the support frame 1. The adjustment rod 7 can adjust the tilt angle of the tray 2.
[0032] The inverting cylinder 6 includes a slide cylinder 601, in which a guide block 602 is inserted; a spiral groove runs through the guide block 602, and the spiral groove and the inner wall of the slide cylinder 601 form an inverting cavity 605, through which the infusion soft pack can spirally pass. A flared guide cover 603 is provided on the inlet of the slide cylinder 601.
[0033] Specifically, one end of the guide block 602 is provided with a connecting part 6021, which is close to the inlet of the slide cylinder 601; a connecting roller 604 is hinged on the connecting part 6021, and one side of the connecting part 6021 smoothly transitions with the spiral groove of the guide block 602.
[0034] Specifically, the adjusting rod 7 includes an adjusting nut 702, on which a first screw 701 and a second screw 703 with opposite thread directions are connected. One end of the first screw 701 is hinged to the support frame 1, and one end of the second screw 703 is hinged to the support plate 2.
[0035] The adjusting nut 702 has two threads with opposite directions at both ends, which can be connected to the first screw 701 and the second screw 703. When the adjusting nut 702 is rotated, the first screw 701 and the second screw 703 can be screwed into the adjusting nut 702 at the same time, or screwed out of the adjusting nut 702 at the same time, so as to quickly complete the length adjustment of the adjusting rod 7.
[0036] Specifically, the clamping device includes: a gasket 4 set on the tray 2, and a clamp 5 sleeved on the slide cylinder 601; the slide cylinder 601 is fitted onto the gasket 4, and the clamp 5 can be fixedly connected to the tray 2.
[0037] Specifically, tray 2 is hollowed out.
[0038] Specifically, both the support frame 1 and the support arm 3 are fixedly connected to the overturned conveyor belt 9;
[0039] The inlet of the slide 601 is connected to the output end of the conveyor belt 8 before it is overturned via the connecting part 6021.
[0040] The specific working principle of this utility model is as follows:
[0041] After being output from the pre-turning conveyor belt 8, the infusion pack first smoothly transitions into the slide drum 601 via the connecting roller 604 of the connecting part 6021. The guide cover 603 provides guidance for the infusion pack, and further, the infusion pack enters the turning chamber 605 along the spiral groove of the guide block 602. With the relative spatial constraint between the slide drum 601 and the guide block 602, the infusion pack completes a 180° axial turn within the spiral turning chamber 605, and finally falls from the outlet end of the slide drum 601 onto the post-turning conveyor belt 9, thus entering the subsequent leak detection process of the light inspection machine.
[0042] During the commissioning phase, manual adjustment of the extension and retraction of the first screw 701, the second screw 703, and the adjusting nut 702 can be performed simultaneously by rotating the adjusting nut 702. This allows the pallet 2 to rotate around the hinge point of the support arm 3, thereby precisely adjusting the tilt angle of the pallet 2 and ensuring a suitable connection slope between the tilting drum 6 and the conveyor belts 8 and 9 before and after tilting. The clamp 5 and the gasket 4 on the hollow pallet 2 cooperate to form a detachable fixing structure, ensuring the positioning stability of the slide drum 601 and facilitating quick disassembly and assembly during maintenance. Throughout the process, the triangular support system formed by the support frame 1 and the support arm 3 effectively maintains the operational stability of the device.
[0043] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
