Description

Technical Field

[0001] This utility model relates to the field of packaging coding technology, and in particular to a coding device installed on a fertilizer product packaging line. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material foundations of agricultural production. They mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional energy-concentrated organic fertilizers.

[0003] Printing production batch numbers on woven bag packaging is essential for every product. Traditionally, a certificate of conformity is placed inside the packaging bag, which is not only inconvenient but also difficult to find when mixed with the product. Now, the code is printed on the packaging bag. However, when the coding device is coding the packaging bag, it is easy to cause unclear coding or missing coding due to wrinkles in the packaging bag. To solve this problem, a coding device that can be installed on fertilizer product packaging lines is provided. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a coding device installed on a fertilizer product packaging line, comprising:

[0005] A material hopper, wherein a receiving port is fixedly provided at the bottom of the material hopper, and a placement groove is provided on the outside of the receiving port;

[0006] The clamping mechanism is set on both sides of the receiving port. The clamping mechanism includes a pair of long boxes and a pair of clamping plates. The pair of long boxes are respectively located on both sides of the receiving port and are mirrored. Each long box is rotatably provided with a double-headed threaded rod. Each long box is slidably provided with a pair of sliders. The sliders are threadedly connected to the double-headed threaded rods. The pair of clamping plates are fixedly connected to the sliders.

[0007] A flattening mechanism is installed on the clamping mechanism. The flattening mechanism includes a pair of rotating rods and a pair of extension rods. One end of each extension rod is hinged to the upper surface of the clamping plate. The other end of each extension rod is slidably disposed inside the rotating rod. The other ends of the pair of extension rods are hinged together. A pull rod is provided at the joint of the hinged ends of the pair of extension rods. A knob is threaded on the pair of rotating rods. The threaded end of the knob passes through the rotating rod and presses against the extension rod. A coding device is fixedly installed on a long box.

[0008] As an improvement to the above technical solution, a support frame is fixedly provided on the outside of the material hopper, and two pairs of fixing rods are fixedly provided at the bottom of the support frame, with the other end of each fixing rod being fixedly connected to the long box.

[0009] As an improvement to the above technical solution, a synchronous pulley is fixedly provided at one end of each of the double-ended threaded rods, a synchronous belt is fitted on a pair of synchronous pulleys, a motor is fixedly provided on the side of one end of the long box of the fixed rod, and the output end of the motor is fixedly connected to a synchronous pulley.

[0010] As an improvement to the above technical solution, the coding device includes a mounting plate, which is fixedly disposed in the middle of the upper surface of a long box. A coding machine slides on the mounting plate, and an electric push rod is fixedly disposed inside the mounting plate. The piston rod end of the electric push rod is fixedly connected to the bottom of the coding machine.

[0011] As an improvement to the above technical solution, the coding device and the flattening mechanism are located on opposite sides of the receiving port, the flattening mechanism and the placement groove are located on the same side, and the pull rod and the placement groove are located on a horizontal line.

[0012] The beneficial effects of this utility model are:

[0013] By using the clamping mechanism, rotating rod, extension rod, and pull rod in combination, when the packaging bag is placed on the receiving port, the clamping plate of the clamping mechanism will move towards the middle of the receiving port. When the clamping plate moves towards the middle, it can push the pull rod away from the receiving port through the rotating rod and extension rod. After the pull rod moves away, the opening of the packaging bag is flattened, so that the packaging bag fits against the outer wall of the receiving port when clamped by the clamping plate. This prevents the bag opening from being too large and wrinkles from forming during clamping, which would affect the coding of the coding machine. Attached Figure Description

[0020] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0021] Printing the production batch number on woven bag packaging is necessary for every product. The traditional practice was to place a prepared certificate of conformity inside the packaging bag, which was not only troublesome but also difficult to find when mixed with the product. Now, the code is printed on the packaging bag. However, when the coding device is coding the packaging bag, it is easy to cause unclear coding or missing coding due to wrinkles in the packaging bag.

[0022] To resolve this issue, please refer to Figure 1-5 A coding device installed on a fertilizer product packaging line includes: a material hopper 1, a material inlet 11 fixedly provided at the bottom of the material hopper 1, and a placement groove 12 opened on the outside of the material inlet 11;

[0023] The clamping mechanism 2 is provided on both sides of the receiving port 11. The clamping mechanism 2 includes a pair of long boxes 22 and a pair of clamping plates 28. The pair of long boxes 22 are mirrored on both sides of the receiving port 11. Each long box 22 is rotatably provided with a double-headed threaded rod 23. Each long box 22 is slidably provided with a pair of sliders 24. The sliders 24 are threadedly connected to the double-headed threaded rods 23. The pair of clamping plates 28 are fixedly connected to the sliders 24.

[0024] The flattening mechanism 4 is installed on the clamping mechanism 2. The flattening mechanism 4 includes a pair of rotating rods 41 and a pair of extension rods 42. One end of the extension rods 42 is hinged to the upper surface of the clamping plate 28, and the other end of the extension rods 42 is slidably installed in the rotating rods 41. The other ends of the pair of extension rods 42 are hinged together. A pull rod 43 is provided at the hinged end of the pair of extension rods 42. A knob 44 is threaded on the pair of rotating rods 41. The threaded end of the knob 44 passes through the rotating rod 41 and presses against the extension rod 42. A coding device 3 is fixedly installed on a long box 22.

[0025] In use, open the clamping mechanism 2 so that the pull rod 43 is in the placement groove 12. Place the opening of the packaging bag over the receiving port 11 so that the pull rod 43 is inside the packaging bag. Rotate the double-headed threaded rod 23. The double-headed threaded rod 23 drives the clamping plate 28 to move towards the receiving port 11 through the slider 24. The clamping plate 28 moves towards the center. The clamping plate 28 adjusts the rotating rod 41 to rotate. The rotating rod 41 drives the pull rod 43 to move away from the receiving port 11 through the extension rod 42. The pull rod 43 moves away from the receiving port 11. By pulling the opening of the packaging bag with the pull rod 43, the wrinkles at the joint between the packaging bag and the receiving port 11 are flattened. Then, the clamping plate 28 clamps and fixes the packaging bag on the receiving port 11 for fertilizer packaging. During the packaging process, the coding device 3 is used to code the packaging bag. Rotating the knob 44 can release the pressure on the extension rod 42, allowing it to be stretched or shortened inwards into the rotating rod 41, thereby adjusting the distance the pull rod 43 moves.

[0026] A support frame 13 is fixedly installed on the outside of the material hopper 1. Two pairs of fixing rods 14 are fixedly installed at the bottom of the support frame 13. The other end of each fixing rod 14 is fixedly connected to the long box 22.

[0027] In use, the material hopper 1 is supported by the support frame 13 to make it stand up, and the fixing rod 14 fixes the long box 22 to both sides of the receiving port 11.

[0028] One end of the double-threaded rod 23 is fixedly equipped with a synchronous pulley 25, and a synchronous belt 26 is fitted on the pair of synchronous pulleys 25. A motor 27 is fixedly installed on the side of one end of the long box 22 of a fixed rod 14, and the output end of the motor 27 is fixedly connected to a synchronous pulley 25.

[0029] In use, the motor 27 drives the double-threaded rod 23 to rotate through the synchronous pulley 25, and the synchronous belt 26 makes the pair of double-threaded rods 23 rotate synchronously. The synchronous rotation of the double-threaded rods 23 drives the clamping plate 28 through the slider 24 to clamp and fix the packaging bag on the docking port 11.

[0030] The coding device 3 includes a mounting plate 31, which is fixedly installed in the middle of the upper surface of a long box 22. A coding machine 32 slides on the mounting plate 31. An electric push rod 33 is fixedly installed inside the mounting plate 31, and the piston rod end of the electric push rod 33 is fixedly connected to the bottom of the coding machine 32.

[0031] In use, after the packaging bag is flattened and clamped and fixed in the receiving port 11, the electric push rod 33 is started. The electric push rod 33 drives the coding machine 32 to move towards the receiving port 11, so that the inkjet nozzle of the coding machine 32 is in contact with the surface of the packaging bag fitted in the receiving port 11 for coding. After coding, the electric push rod 33 drives the coding machine 32 back to its original position.

[0032] The coding device 3 and the flattening mechanism 4 are located on opposite sides of the receiving port 11. The flattening mechanism 4 and the placement groove 12 are located on the same side. The pull rod 43 and the placement groove 12 are located on the horizontal line.

[0033] When in use, the flattening mechanism 4 and the coding device 3 are located on opposite sides so that when the pull rod 43 pulls the opening of the packaging bag, the packaging bag on the side of the coding device 3 is flat, which makes it convenient for the coding machine 32 to code. When the clamping plate 28 separates to both sides, the pull rod 43 is moved into the placement groove 12 by the rotating rod 41 and the extension rod 42, which makes it convenient for the packaging bag to be put on the receiving port 11.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
