Description

Technical Field

[0001] This utility model specifically relates to the field of adhesive application technology for packaging box cushioning materials, and more specifically to an adhesive application device for plastic cushioning materials used in packaging cartons. Background Technology

[0002] Packaging boxes are containers used to package products for transportation, storage, and sale. To protect the goods inside the packaging boxes, plastic cushioning materials are usually placed inside. During transportation and storage, the plastic cushioning materials can absorb impact and prevent the goods from being damaged by collisions and vibrations. Plastic cushioning materials are generally made of foam plastic that has been cut and pasted together. Therefore, after the plastic cushioning materials are cut, they need to be glued using a dispensing machine and then pasted manually.

[0003] However, in practice, it has been noted that existing dispensing machines require manual application of glue. Workers place the plastic buffer material under the dispensing valve and then manually control the valve to dispense the glue. This is not only inefficient, but also prone to glue separation at the joints when manually stacking plastic buffer materials, affecting the bonding quality. Automatic dispensing machines still require manual positioning and clamping of the plastic buffer material, which takes time and reduces dispensing efficiency. Furthermore, positioning affects dispensing accuracy. Therefore, it is impossible to simultaneously position the plastic buffer material and improve dispensing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a plastic cushioning material dispensing device for packaging cartons. The material conveyor belt and edge positioner work together to simultaneously prevent and position the plastic cushioning material. Furthermore, the Y-axis moving module, X-axis linear motor, and Z-axis lifting module work together to control the glue control valve for automatic dispensing, eliminating the need for manual operation, reducing labor intensity, and ensuring dispensing accuracy. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A plastic cushioning material dispensing device for packaging cartons includes a frame body, with Y-axis moving modules symmetrically fixedly connected to the top of the frame body.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-10 This utility model provides a plastic cushioning material dispensing device for packaging cartons, including a frame body 2. The top of the frame body 2 is symmetrically fixedly connected with Y-axis moving modules 11. Each Y-axis moving module 11 is provided with a protective plate 10 on its side. The protective plate 10 is C-shaped and fixedly connected to the frame body 2.

[0033] An X-axis linear motor 13 is movably connected between the two Y-axis moving modules 11. A Z-axis lifting module 14 is movably connected to the side of the X-axis linear motor 13. An adhesive control valve 15 is fixedly connected to the front of the Z-axis lifting module 14.

[0034] In this embodiment, an outer frame 3 is fixedly connected to the frame body 2, and a material conveyor belt 4 is movably connected to the outer frame 3. An edge locator 5 is provided at the end of the outer frame 3, and a buffer plate 9 is also provided at the end of the outer frame 3 away from the edge locator 5.

[0035] In this embodiment, the edge locator 5 includes a U-shaped slide 53 that is slidably connected to the end of the outer frame 3, and a locking knob is threadedly connected to the side of the U-shaped slide 53. The end of the locking knob passes through the U-shaped slide 53 and fits against the outer frame 3.

[0036] In this embodiment, the inner side of the U-shaped slide 53 is also provided with a positioning protrusion 54 corresponding to the outer side of the outer frame 3, and a limiting frame 51 is fixedly connected above the U-shaped slide 53, and the limiting frame 51 is located above the material conveyor belt 4.

[0037] In this embodiment, the side of the limiting frame 51 is provided with a groove 52, and a guide belt 55 is movably connected in the groove 52. The inner side of the guide belt 55 is provided with a plurality of support rollers 551 in a rectangular array, and each of the support rollers 551 is movably connected to the limiting frame 51.

[0038] In this embodiment, an electric cylinder 8 is fixedly connected above the buffer plate 9, and a rear frame 7 is fixedly connected to the outside of the electric cylinder 8. The rear frame 7 is fixedly connected to the end of the outer frame 3, and the buffer plate 9 is located above the material conveyor belt 4.

[0039] In this embodiment, the buffer plate 9 includes a plate seat 91 fixedly connected to the end of the electric cylinder 8. The bottom of the plate seat 91 is provided with positioning grooves 92 in a rectangular array, and a magnet 93 is embedded in each positioning groove 92.

[0040] In this embodiment, two side limiting plates 94 are symmetrically arranged at the bottom of the pressure plate seat 91. Each side limiting plate 94 is fixedly connected with a number of metal adsorption plates 95 corresponding to the magnet 93. The metal adsorption plates 95 are placed inside the positioning groove 92 and are in contact with the magnet 93.

[0041] By adopting the above technical solution, the plastic buffer is placed on the material conveyor belt 4, and the side of the plastic buffer is in contact with the guide belt 55. The material conveyor belt 4 is rotated by the servo motor, so that the plastic buffer moves to the bottom of the glue control valve 15. Then, through the cooperation of the Y-axis moving module 11, the X-axis linear motor 13 and the Z-axis lifting module 14, the glue control valve 15 performs glue dispensing operation on the plastic buffer according to a specific program. The whole process does not require manual operation, reducing labor intensity. The plastic buffer continues to move to the bottom of the buffer plate 9, and the buffer plate 9 and the electric cylinder 8 cooperate to press the plastic buffers together, preventing the phenomenon of gaps at the joint after manual pasting and improving the quality of plastic buffer pasting.

[0042] In this embodiment, a controller 1 is fixedly connected to the side of the frame 2. A control screen is embedded at the end of the controller 1. A control module is installed inside the controller 1. The control module is electrically connected to the Y-axis moving module 11, the X-axis linear motor 13, the Z-axis lifting module 14, and the glue control valve 15.

[0043] The control module receives instructions via the control panel. The control module then controls the Y-axis moving module 11, the X-axis linear motor 13, and the Z-axis lifting module 14 to move according to the instructions. This controls the position of the glue control valve 15, allowing the glue control valve 15 to apply glue to the plastic buffer material according to the instructions.

[0044] In this embodiment, a horizontal plate is fixedly connected above the buffer plate 9, and an electric cylinder 8 is fixedly connected to the horizontal plate. The end of the electric cylinder 8 passes through the horizontal plate and is fixedly connected to the pressure plate seat 91 below by bolts. The electric cylinder 8 pushes the pressure plate seat 9 to move downward, and the pressure plate seat 9 applies pressure to the plastic buffer material that is attached together, thereby compacting the plastic buffer material and preventing gaps from appearing at the connection position.

[0045] In this embodiment, the side of the side limiting plate 94 is tapered. When the pressure plate seat 91 moves downward, the side limiting plate 94 slowly inserts into the groove of the plastic buffer to position the plastic buffer and prevent sliding displacement during the application of pressure.

[0046] The cooperation between the metal adsorption sheet 95 and the magnet 93 allows for easy and quick adjustment of the position of the side limiting plate 94 based on the groove position of the plastic buffer.

[0047] In this embodiment, the Y-axis moving module 11 includes a slide rail, a slide table, and a threaded screw. The slide rail and the slide table are slidably connected, and the slide table is fixedly connected to both ends of the X-axis linear motor 13. The two ends of the threaded screw are movably connected to the slide rail, and the threaded screw is threadedly engaged with the slide table.

[0048] Through the threaded engagement between the lead screw and the slide, when the lead screw rotates, the slide can drive the X-axis linear motor 13 to slide back and forth on the slide rail, and a transmission gear is fixedly connected to the end of the lead screw.

[0049] In this embodiment, a corner bracket 6 is fixedly connected to the end of the slide rail, and a transmission link 12 is movably connected to the corner bracket 6. Both ends of the transmission link 12 are connected to bevel gears 121, and the bevel gears 121 mesh with the transmission gear at the end of the threaded screw.

[0050] In this embodiment, the end of the transmission link 12 extends into the controller 1, a drive motor is installed inside the controller 1, and the end of the drive motor is connected to the transmission link 12 in a transmission connection.

[0051] The drive motor drives the transmission link 12 to rotate. The transmission link 12 drives the threaded screws in the two Y-axis moving modules 11 to rotate simultaneously through the meshing between the bevel gear 121 and the transmission gear, thereby driving the X-axis linear motor 13 to move as a whole.

[0052] The working principle of this utility model is as follows: In use, first, place the plastic buffer material onto the material conveyor belt 4, ensuring the side of the plastic buffer material is in contact with the guide belt 55 to position it. The position of the limiting frame 51 can also be adjusted as needed. Loosen the threaded knob on the side of the U-shaped slide 53, causing the U-shaped slide 53 to slide above the material conveyor belt 4. Adjusting the position of the limiting frame 51 causes the material conveyor belt 4 to move the plastic buffer material, and the guide belt 55 rotates with the plastic buffer material to prevent it from shifting due to friction during movement. The system moves to the area below the glue control valve 15. The control module, according to instructions, controls the Y-axis moving module 11, the X-axis linear motor 13, and the Z-axis lifting module 14 to work together to drive the glue control valve 15 to perform automatic glue dispensing. After dispensing, the material conveyor belt 4 moves the plastic buffer material. During the movement, the worker places the upper layer of plastic buffer material to be pasted onto the processed plastic buffer material. The two layers of plastic buffer material move to the area below the buffer material pressure plate 9. The electric cylinder 8 pushes the pressure plate seat 91 downward to compact the plastic buffer material and prevent gaps from appearing at the joint. This effectively reduces the intensity of manual labor.
