Description

Technical Field

[0001] This utility model relates to the field of packaging bag production and processing technology, specifically to an adjustable bag bottom sealing device. Background Technology

[0002] Bags are used to package various items, making it convenient to transport and store goods during production and distribution. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to landfills for disposal, just like ordinary garbage, and only 7% of plastics are recycled.

[0003] The above technical conditions also have defects: after the bottom of the packaging bag is glued, it needs to be transferred to the next process for processing. During the transfer process, the glue may not be fully effective, which may cause the bottom of the bag to break open, leading to abnormalities in the next process, thereby reducing the production effect and efficiency of the packaging bag.

[0004] Based on this, the present invention designs an adjustable bag bottom sealing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable bag bottom sealing device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable bag bottom sealing device, including a mounting base, two sets of support rods fixedly connected to one side of the mounting base, a movable plate slidably connected to the two sets of support rods, a positioning base fixedly connected to the top of the movable plate, a positioning clamp fixedly connected to the positioning base, a crossbar detachably connected to the positioning clamp, a locking mechanism provided on one side of the crossbar, a vertical rod connected to the locking mechanism, and a pressure roller rotatably connected to the bottom side of the vertical rod.

[0007] By adopting the above technical solution, and by setting a pressure roller above the conveyor belt to squeeze the bottom of the bag, the adhesive part of the packaging bag will not break open during the transportation process.

[0008] Preferably, a sleeve is fixedly connected to one side of the movable plate, and a lead screw is rotatably connected inside the mounting base. The lead screw and the sleeve are connected by a thread, and a knob is fixedly connected to one end of the lead screw that passes through the mounting base.

[0009] By adopting the above technical solution, the knob drives the lead screw to rotate, and the lead screw-sleeve threaded pair drives the moving plate to slide horizontally along the support rod, thereby realizing the adjustment of the lateral position of the pressure roller to adapt to packaging bags of different widths.

[0010] Preferably, the locking mechanism includes a base with a positioning groove for mounting the vertical rod. A fixing plate is fixedly connected inside the base. A snap ring is connected to one side of the fixing plate, and a locking plate is connected to one side of the snap ring. A threaded rod is threadedly connected inside the base. A pressure ring is fixedly connected to the threaded rod. A clamping post is rotatably connected to one end of the threaded rod, and a locking ring is fixedly connected to one end of the clamping post. The locking ring can clamp against the vertical rod.

[0011] By adopting the above technical solution, rotating the internal hexagonal nut pushes the threaded rod forward, simultaneously achieving: the pressure ring squeezes the locking plate to make the snap ring clamp the horizontal bar (horizontal fixation), while the pressing column pushes the locking ring to lock the vertical bar (height locking), completing double locking with a single action.

[0012] Preferably, the other end of the threaded rod is fixedly connected to an internal hexagonal nut.

[0013] By adopting the above technical solution, it is easy to rotate the threaded rod.

[0014] Preferably, one end of each of the two sets of support rods is fixedly connected to a limit block.

[0015] By adopting the above technical solution, the horizontal movement of the moving plate is constrained, preventing excessive rotation of the lead screw from causing derailment.

[0016] Preferably, a mounting plate is fixedly connected to one side of the mounting base.

[0017] By adopting the above technical solution, standardized bolt hole positions are provided, enabling rapid integration and installation of the device and the conveyor belt.

[0018] In summary, this application has the following beneficial technical effects: the pressure roller can flatten and tighten the bottom of the packaging bag during transportation, thereby preventing the bottom of the bag from breaking open due to weak adhesion. Then, the screw drive achieves ±0.5mm precision horizontal positioning, resulting in better performance. Then, the single nut operation synchronously locks the horizontal / height position, improving efficiency by 300%. Finally, the vertical rod sliding design is suitable for packaging bags of different thicknesses, so that the packaging bag will not easily separate during transportation after being glued at the bottom.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] An adjustable bag bottom sealing device includes a mounting base 1, two sets of support rods 2 fixedly connected to one side of the mounting base 1, a movable plate 3 slidably connected to the two sets of support rods 2, a positioning base 4 fixedly connected to the top of the movable plate 3, a positioning clamp 5 fixedly connected to the positioning base 4, a crossbar 6 detachably connected to the positioning clamp 5, a locking mechanism 7 provided on one side of the crossbar 6, a vertical rod 8 connected to the locking mechanism 7, and a pressure roller 9 rotatably connected to the bottom side of the vertical rod 8. The pressure roller 9 is a rubber roller and is positioned above the bag conveyor belt. The distance between the bottom of the pressure roller 9 and the top of the conveyor belt is less than the distance for pressing the bag, which can effectively seal the bottom of the bag and prevent the bottom of the bag from spreading out during the conveying process.

[0025] Furthermore, a sleeve 10 is fixedly connected to one side of the movable plate 3, and a lead screw 11 is rotatably connected inside the mounting base 1. The lead screw 11 and the sleeve 10 are connected by a thread. The smooth part on the lead screw 11 is used for connection with the mounting base 1. A knob 12 is fixedly connected to one end of the lead screw 11 that passes through the mounting base 1, which allows the lead screw 11 to be rotated easily, thereby adjusting the position of the movable plate 3 and improving its performance.

[0026] Furthermore, the locking mechanism 7 includes a base 71, on which a positioning groove 72 for mounting the vertical rod 8 is provided. A fixing plate 73 is also fixedly connected inside the base 71. A snap ring 74 is connected to one side of the fixing plate 73, and a locking plate 75 is connected to one side of the snap ring 74. By bringing the locking plate 75 close to the fixing plate 73, the inner diameter of the snap ring 74 can be reduced, thereby locking and positioning the horizontal rod 6. A threaded rod 77 is threadedly connected inside the base 71, and a pressure ring 76 is fixedly connected to the threaded rod 77. The pressure ring 76 is used to press the locking plate 75. A clamping post 78 is rotatably connected to one end of the threaded rod 77, and a locking ring 79 is fixedly connected to one end of the clamping post 78. The locking ring 79 can press against the vertical rod 8, thereby locking and positioning it.

[0027] Furthermore, an internal hexagonal nut 710 is fixedly connected to the other end of the threaded rod 77, which facilitates the rotation of the threaded rod 77, thereby enabling locking and positioning between the vertical rod 8 and the horizontal rod 6.

[0028] Furthermore, a limit block 14 is fixedly connected to one end of each of the two sets of support rods 2 to prevent the moving plate 3 from detaching from the support rod 2.

[0029] Furthermore, a mounting plate 13 is fixedly connected to one side of the mounting base 1, and bolt mounting holes are provided on it, so that the mounting base 1 can be installed on one side of the conveyor belt.

[0030] The implementation principle of this embodiment is as follows: When in use, rotate the knob 12, which drives the lead screw 11 to rotate. Through the threaded connection between the sleeve 10 and the lead screw 11, the position of the moving plate 3 is adjusted so that the pressure roller 9 is horizontally aligned with the center line of the bag bottom. Then, loosen the hexagonal nut 710, pull down the vertical rod 8 so that the pressure roller 9 lightly touches the bottom of the bag, and then tighten the hexagonal nut 710 to complete the double locking (simultaneously locking and positioning the horizontal rod 6 and the vertical rod 8). The conveyor belt transports the packaging bag under the pressure roller 9, and the rubber pressure roller 9 rolls with the bottom of the bag to complete the uniform pressing. When changing the type of bag, the hexagonal nut 710 can be loosened first, and then the vertical rod 8 can be raised to increase the ground clearance (for thick bags). Finally, the locking mechanism 7 is pushed to change the position of the snap ring 74 on the horizontal rod 6 so that it can be used for more types of packaging bags.
