The front and rear ends of the waterproof box are provided with inlets for the paper-plastic shells to enter and exit. A water-blocking curtain is provided above each inlet. Longitudinal water pipes are symmetrically arranged on both sides of the inlets, and several transverse water pipes are arranged above the longitudinal water pipes along the conveying direction. Both the longitudinal and transverse water pipes are equipped with several nozzles for uniformly spraying water onto the paper-plastic shells. Both the longitudinal and transverse water pipes are fixed inside the waterproof box. Each paper-plastic positioning component includes four vertically positioned limiting posts fixed to the corresponding chains. The four limiting posts are rectangularly distributed and match the inner wall contour of the paper-plastic shell.

[0005] Furthermore, both ends of the frame are rotatably provided with shafts, and sprockets matching the corresponding chains are fixed on the shafts. One of the shafts is driven to rotate by a motor, which is fixed on the frame.

[0006] Furthermore, the top of the outer chain plate of the chain is integrally provided with a flat plate corresponding to the position of the limiting post, and the limiting post is bolted and fixed on the flat plate.

[0007] Furthermore, the limiting post is a nylon rod or a plastic rod.

[0008] Furthermore, a photoelectric sensor is provided on the outside of the material inlet at the front end of the waterproof box, and the photoelectric sensor is fixed on the frame.

[0009] Furthermore, a water receiving tray is provided inside the frame, and a return water pipe is connected to one end of the water receiving tray.

[0010] Furthermore, the nozzle of the longitudinal water pipe is horizontally aligned with the side of the paper-plastic shell.

[0011] Furthermore, there are three horizontal water pipes; the nozzle on the horizontal water pipe at the front end of the waterproof box is tilted towards the corresponding material inlet; the nozzle on the horizontal water pipe in the middle of the waterproof box faces downwards and directly towards the upper surface of the paper-plastic shell; and the nozzle on the horizontal water pipe at the rear end of the waterproof box is tilted towards the corresponding material inlet.

[0012] Furthermore, one end of both the longitudinal water pipe and the transverse water pipe is provided with a flange for fixing and connecting the waterproof box.

[0013] Furthermore, the two sides of the waterproof box are bolted and fixed to the frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the paper-plastic shell is positioned by the four limiting posts of the paper-plastic positioning component, and the paper-plastic shell is driven into the waterproof box by the chain. The longitudinal water pipe and the transverse water pipe in the waterproof box perform a uniform water spraying operation on the paper-plastic shell, thereby reducing costs and improving the pass rate of the paper-plastic shell.

[0021] Example

[0022] Please see Figures 1 to 3 This utility model provides an automatic water spraying device for paper-plastic shells, including a frame 1 and several paper-plastic positioning components 3. Two synchronously rotating chains 2 are arranged longitudinally inside the frame 1. A waterproof box 4 is fixed at the top of the frame 1. The front and rear ends of the waterproof box 4 are provided with material inlets for paper-plastic shells to enter and exit. A water curtain 5 is provided on the material inlet. Longitudinal water pipes 6 are symmetrically arranged on both sides of the material inlet. Several transverse water pipes 7 are arranged above the longitudinal water pipes 6 along the conveying direction. Both the longitudinal water pipes 6 and the transverse water pipes 7 are provided with several nozzles for uniform water spraying of the paper-plastic shells. Both the longitudinal water pipes 6 and the transverse water pipes 7 are fixed inside the waterproof box 4. The paper-plastic positioning components 3 include four vertical limiting posts 31 fixed on the corresponding chains 2. The four limiting posts 31 are rectangularly distributed and match the inner wall contour of the paper-plastic shell.

[0023] Specifically, both ends of the frame 1 are provided with rotating shafts 21, and sprockets 22 that match the corresponding chains 2 are fixed on the rotating shafts 21. One of the rotating shafts 21 is driven to rotate by a motor 23, which is fixed on the frame 1, so as to realize the synchronous rotation of the two chains 2.

[0024] As one embodiment of the present invention, the top of the outer chain plate of the chain 2 is integrally provided with a flat plate corresponding to the position of the limiting post 31, and the limiting post 31 is bolted and fixed on the flat plate to facilitate the installation of the limiting post 31.

[0025] The aforementioned limiting post 31 is preferably a nylon rod or a plastic rod.

[0026] As one embodiment of this utility model, a photoelectric sensor 8 is provided on the outside of the material inlet at the front end of the waterproof box 4. The photoelectric sensor 8 is fixed on the frame 1 so as to sense the paper-plastic shell and control the spraying of water from the longitudinal water pipe 6 and the transverse water pipe 7.

[0027] As one embodiment of this utility model, the frame 1 is also provided with a water receiving tray 9, one end of which is connected to a return water pipe 91, so as to facilitate wastewater collection and reuse and save costs.

[0028] In one embodiment of this utility model, the nozzle of the longitudinal water pipe 6 is horizontally facing the side of the paper-plastic shell. There are three transverse water pipes 7; the nozzle on the transverse water pipe 7 located at the front end of the waterproof tank 4 is angled towards the corresponding feed inlet; the nozzle on the transverse water pipe 7 located in the middle of the waterproof tank 4 faces downwards towards the upper surface of the paper-plastic shell; and the nozzle on the transverse water pipe 7 located at the rear end of the waterproof tank 4 is angled towards the corresponding feed inlet. Through the aforementioned positions of the longitudinal water pipes 6 and transverse water pipes 7, water can be automatically and evenly sprayed onto the upper surface and four sides of the paper-plastic shell.

[0029] In addition, both the longitudinal water pipe 6 and the transverse water pipe 7 can be equipped with flanges at one end for fixing the waterproof box 4, improving installation convenience. The two sides of the waterproof box 4 are bolted to the frame 1 for easy assembly and disassembly.

[0030] In use, the front-end employee of this invention picks up the paper-plastic shell and places it on the four limiting posts 31 of the paper-plastic positioning component 3. The chain 2 drives the paper-plastic shell to move longitudinally. When the photoelectric sensor 8 senses the paper-plastic shell, the longitudinal water pipe 6 and the transverse water pipe 7 automatically spray water onto the paper-plastic shell. The rear-end employee puts the paper-plastic shell into the turnover box for storage, thereby significantly improving work efficiency, saving manpower, and reducing costs; moreover, the water spray is uniform, and the yield of paper-plastic shells is further improved.

[0031] It should be noted that the end of the paper-plastic shell that enters the waterproof box 4 is the front end, and the end of the paper-plastic shell that leaves the waterproof box 4 is the rear end.
