Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] Water-soluble fertilizer packaging bags are generally made of plastic or aluminum foil. There are generally two sealing methods for these bags. For larger capacity bags, a sealing line is often used, while for smaller water-soluble fertilizer granules and smaller quantities, heat fusion sealing is often used. The inventors discovered that the packaging equipment used in mass production lines in factories is large and requires integration with other production equipment, making it costly for small factories or individual users. For example, individual users often leave opened but unused water-soluble fertilizers open or use simple folding methods to seal them, resulting in poor sealing and easy for the fertilizer to absorb moisture and become ineffective. If there were a portable sealing device that could be used immediately, it would improve the sealing efficiency of water-soluble fertilizer packaging bags for small factories or individual users.

[0028] First embodiment:

[0029] like Figure 1 As shown, the packaging device for water-soluble fertilizer production provided by this utility model includes: a hand-held part 10 and a sealing part 20 installed on the hand-held part 10 for sealing the water-soluble fertilizer packaging bag;

[0030] Specifically, the handheld part 10 is similar to the handheld part of a conventional electric drill, including a handle 11 for gripping, the handle 11 being shaped as follows: Figure 1As shown, the upper part of the handle 11 is the housing 12, and the housing 12 has a cavity inside. The lower end of the handle 11 is the battery 13. This device adopts a heat-sealing method. The battery 13 provides power to the first heating strip 211 and the second heating strip 221 to raise their dimensions, thereby providing conditions for melting the bag opening. The specific structure of the first heating strip 211 and the second heating strip 221 will be described in detail below.

[0031] like Figure 1 , Figure 2 As shown, the sealing part 20 includes an upper shell 21 and a lower shell 22. Both the upper shell 21 and the lower shell 22 are square boxes with internal cavities. A connecting plate 23 is vertically installed between the upper shell 21 and the lower shell 22 to connect and fix them. The upper end of the connecting plate 23 is fixedly installed on the lower surface of the upper shell 21, and its lower end is fixedly installed on the upper surface of the lower shell 22. The upper shell 21 is partially fixedly connected to the housing 12, and the lower shell 22 is partially connected to the housing 12 via a connecting rod 14, thus forming a closed structure. Sealing components are installed inside both the upper shell 21 and the lower shell 22. Figure 2 As shown, the sealing assembly includes an insulation box 212 fixedly installed at the lower end of the upper shell 21. The insulation box 212 is a square box structure made of ceramic material, and an electric heating wire (not shown in the figure) is arranged inside it. The battery 13 provides power to the electric heating wire, and the electric heating wire converts the power into heat energy. On the other hand, a slot is opened at the lower end of the insulation box 212. The first heating strip 211 made of metal material that matches the size of the slot is fixed in the slot by an interference fit. Its installation direction is parallel to the movement direction when sealing the mouth of the water-soluble fertilizer bag. The second heating strip 221 located on the lower shell 22 has the same structure as the first heating strip 211. At the same time, the connection method with the lower shell 22 is the same as the connection method between the first heating strip 211 and the upper shell 21. It will not be described again here. It should be noted that the first heating strip 211 and the second heating strip 221 are directly opposite each other, and there is a strip between them that presses down on the water-soluble fertilizer packaging bag and passes through the slit.

[0032] In use, battery 13 provides power to heating wire. After the heating wire is powered on, it heats up and then heats the first heating strip 211 and the second heating strip 221 nearby. Then, the packaging bag is placed between the first heating strip 211 and the second heating strip 221. The handheld device slides from one end of the packaging bag opening to the other end. After the packaging bag comes into contact with the heated first heating strip 211 and the second heating strip 221, it melts and the two sides of the bag opening fuse together. After cooling, it is fixed together to complete the seal.

[0033] The device achieves a sealing effect on water-soluble fertilizer packaging bags by setting up a hand-held part 10 and a sealing part 20. Compared with the existing assembly line sealing method, the device is lightweight and flexible, can be used in a variety of environments, and is suitable for sealing small batches of packaging bags.

[0034] Second embodiment:

[0035] like Figure 2 As shown, the lower end of the upper shell 21 has a through hole for the mounting base 213 to pass through, and the heat preservation box 212 is glued and fixed to the lower end of the mounting base 213. The upper end of the mounting base 213 is fixed with a sliding plate 214 that slides along the inner wall of the upper shell 21. In this way, when the sliding plate 214 moves upward, it drives the heat preservation box 212 and the first heating strip 211 to move upward synchronously. A baffle 218 is horizontally fixed to the inner wall of the upper shell 21 above the sliding plate 214. A rod is provided between the baffle 218 and the sliding plate 214. Spring 215, wherein the upper end of spring 215 is fixed on baffle 218 and the lower end is fixed on slide plate 214. In order to prevent spring 215 from bending laterally, a cylindrical guide seat 216 is fixedly installed on baffle 218 and slide plate 214, which is sleeved around spring 215. Spring 215 is always in a compressed state. That is to say, the first heating strip 211 and the second heating strip 221 are in contact with each other in the initial state. The connection method between the second heating strip 221 and the lower shell 22 is the same as that in the first embodiment.

[0036] When using, such as Figure 2 As shown, first turn on the power, the first heating strip 211 and the second heating strip 221 heat up, then push the mounting base 213 upward to move the first heating strip 211 upward so that it separates from the second heating strip 221, and finally clamp the first heating strip 211 and the second heating strip 221 at the mouth of the water-soluble fertilizer packaging bag and slide the device to complete the sealing.

[0037] By setting spring 215 and other related components, the distance between the first heating strip 211 and the second heating strip 221 can be adjusted, making it easy for the bag opening to be clamped between the two.

[0038] Third embodiment:

[0039] like Figure 3 , Figure 4 As shown, the first heating strip 211 and the second heating strip 221 are replaced with circular rollers 217. The lower end of the heat preservation box 212 is open and hollow inside. The rollers 217 are rotatably installed at the lower end of the heat preservation box 212. Similarly, the upper end of the lower shell 22 is fixedly provided with a mounting base 213, and the heat preservation box 212 is fixedly installed on the mounting base 213. The upper end of the heat preservation box 212 is open, and a metal roller 217 is rotatably installed at the upper end of the heat preservation box 212. Its structure is consistent with and symmetrical to the structure of the mounting base 213 of the upper shell 21.

[0040] By setting roller 217, the frictional resistance with the packaging bag can be reduced, making operation easier.

[0041] Fourth embodiment:

[0042] like Figure 2As shown, a pull rod 24 is fixedly installed on the mounting base 213. The other end of the pull rod 24 passes through the baffle 218 and the hole in the inner wall of the upper shell 21 for it to pass through. The upper end is located outside the upper shell 21. Pulling the pull rod 24 upward can drive the mounting base 213 on the upper shell 21 to move upward, which facilitates the separation of the first heating strip 211 and the second heating strip 221.

[0043] Fifth embodiment:

[0044] like Figure 1 As shown, heat dissipation windows 25 are provided on the outer walls of the upper shell 21 and the lower shell 22, and excess heat generated inside the device can be released to the outside through the heat dissipation windows 25.

[0045] Working principle: Battery 13 provides power to the heating wire. When energized, the heating wire heats up, thereby heating the nearby first heating strip 211 and second heating strip 221. The packaging bag is then positioned between the first heating strip 211 and second heating strip 221. A handheld device slides from one end of the packaging bag opening to the other. Upon contact with the heated first heating strip 211 and second heating strip 221, the packaging bag melts, fusing the two sides of the bag opening. After cooling, the bags are fixed together to complete the seal. The above embodiment is only one preferred embodiment of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not substantial in nature, but which still solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
