Description

Technical Field

[0001] This utility model relates to the field of packaging bag manufacturing, and in particular to a label pressing device for packaging bags. Background Technology

[0002] In recent years, with the development of the express delivery industry, the transmission of documents has become faster, and the production of document packaging bags has increased dramatically. During the production of packaging bags, various manufacturers will imprint their own trademark patterns on the packaging bags, but the existing labeling devices can only be adapted to single imprinting conveyor machines.

[0003] Therefore, it is necessary to design a highly adaptable labeling device for packaging bags. Utility Model Content

[0004] The technical problem to be solved by this utility model is that during the production of packaging bags, each manufacturer will imprint their own trademark pattern on the packaging bag, but the existing imprinting device can only be adapted to a single imprinting conveyor machine.

[0005] To solve the above-mentioned technical problems, the present invention provides a label pressing device for packaging bags, the label pressing device including a main shaft, telescopic rods inserted and slidably connected to both sides of the main shaft, a support rod fixedly connected to the other end of the telescopic rod, a support plate provided at the bottom of the support rod, a nut installed on the support plate, and a label pressing assembly installed on the main shaft.

[0006] The marking assembly includes a telescopic kit and a marking kit.

[0007] The telescopic assembly includes a fixed rod and a sliding rod. The sliding rod is slidably inserted into the fixed rod. A sliding groove is provided in the fixed rod, and a slider is slidably connected in the sliding groove. The sliding rod is connected to the bottom of the slider. The pressure mark assembly is connected to the other end of the sliding rod. An air pump is installed on the top of the main shaft. An air port is opened on the top of the fixed rod, and the output end of the air pump is connected to the air port.

[0008] The marking kit includes a marking crossbar, with shafts inserted on both sides of the bottom of the marking crossbar. A pull block is fixedly installed on the outer end of the shaft, and a tension spring is fixedly connected to the inner side of the pull block. The other end of the tension spring is fixedly connected to the outer wall of the shaft. A marking post is provided below the shaft, and an insertion hole is opened in the center of the marking post. The shaft is inserted into the insertion hole.

[0009] A spring is installed inside the fixed rod. One end of the spring is fixedly connected to the inner top of the fixed rod, and the other end of the spring is fixedly connected to the top of the sliding rod.

[0010] The beneficial effects of this utility model are as follows:

[0011] Equipped with a telescopic rod, sliding groove, and tension spring, the nut is tightened to connect it to the conveyor. The telescopic rod allows for adjustment of the distance between the support rods, thus adapting to various wide-distance conveyors. When the air pump is started, it pumps air into the fixed rod through the air inlet. The air pressure at the top of the fixed rod gradually increases, pushing the slider downwards, which in turn moves the sliding rod downwards, causing the marking assembly to move downwards as well. The tension spring constantly pulls the pull block towards the marking crossbar, causing the shaft to insert into the insertion hole. The marking column rotates axially about the shaft. When the pull block is pulled outwards, the shaft moves accordingly, disengaging from the insertion hole, allowing the marking column to be replaced. After the marking operation is completed, the air pump is turned off, and the spring pulls the slider upwards, automatically resetting the marking assembly. Attached Figure Description

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0019] Please see Figure 1-5 The marking device includes a main shaft 1, with telescopic rods 2 inserted and slidably connected to both sides of the main shaft 1. A support rod 3 is fixedly connected to the other end of the telescopic rod 2. A support plate 4 is provided at the bottom of the support rod 3, and a nut 5 is installed on the support plate 4. The marking assembly is installed on the main shaft 1. The nut 5 is screwed to connect it to the conveyor. Since the telescopic rod 2 can extend and retract, the distance between the support rods 3 can be adjusted, thus adapting to various wide-distance conveyors.

[0020] The marking assembly includes a telescopic kit and a marking kit.

[0021] The telescopic assembly includes a fixed rod 6 and a sliding rod 7. The sliding rod 7 is slidably inserted into the fixed rod 6. The fixed rod 6 has a sliding groove 8, and a slider 9 is slidably connected in the sliding groove 8. The sliding rod 7 is connected to the bottom of the slider 9. The pressure mark assembly is connected to the other end of the sliding rod 7. An air pump 10 is installed on the top of the main shaft 1. An air port 11 is opened on the top of the fixed rod 6. The output end of the air pump 10 is connected to the air port 11. When the air pump 10 is started, the air pump 10 will pump air into the fixed rod 6 through the air port 11. The air pressure in the upper part of the fixed rod 6 gradually increases, which will gradually push the slider 9 downward, thereby driving the sliding rod 7 downward, and the pressure mark assembly downward.

[0022] The label-pressing kit includes a label-pressing crossbar 12, with shafts 13 inserted into both sides of the bottom of the crossbar 12. Pull blocks 14 are fixedly installed on the outer ends of the shafts 13, and tension springs 15 are fixedly connected to the inner sides of the pull blocks 14. The other end of the tension springs 15 is fixedly connected to the outer wall of the shafts 13. A label-pressing post 16 is provided below the shafts 13, and an insertion hole 17 is opened in the center of the label-pressing post 16. The shafts 13 are inserted into the insertion holes 17. The tension springs 15 always pull the pull blocks 14 toward the side of the label-pressing crossbar 12, so that the shafts 13 are inserted into the insertion holes 17. The label-pressing post 16 rotates axially about the shafts 13. When the pull blocks 14 are pulled outward, the shafts 13 move accordingly and are pulled out of the insertion holes 17, so that the label-pressing post 16 can be replaced.

[0023] A spring 18 is installed inside the fixed rod 6. One end of the spring 18 is fixedly connected to the inner top of the fixed rod 6, and the other end of the spring 18 is fixedly connected to the top of the slide rod 7. After the marking operation is completed, the air pump 10 is turned off, and the spring 18 will pull the slider 9 up, so that the marking kit will automatically reset.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
