Description

Technical Field

[0002] The spraying process has existed for a long time, but it is mostly used for knitted products and arts and crafts. In the commonly used spraying process, the thin and short wool lines are vertically erected on the sprayed material by discharging and utilizing the attraction of positive and negative charges at a narrow distance. Of course, before spraying, glue must be sprayed on the sprayed material according to the set pattern, and then the spray is sprayed on the pulp molded product (three-dimensional or flat). Especially three-dimensional pulp molded products are difficult to place and move in a flat surface because of their three-dimensional shape. The first step of gluing cannot be achieved by a printing machine. The spacing and movement of the spraying need to be monitored in real time to ensure the quality rate. The existing technology cannot monitor the spraying process, resulting in low production efficiency and high defective rate. Summary of the invention

Excess glue falls on the conveyor belt 102 and seeps from the glue leakage holes of the conveyor belt 102. During the operation of the conveyor belt 102, it is scraped off by the scraper 105 and collected in the liquid infusion pipe 109, and finally collected in the glue storage box 110 from the liquid infusion pipe 109. The above-mentioned insulation sleeve 107 and the electric heating pipe 108 are used to keep the temperature in the liquid infusion pipe 109 within a suitable range, so that the excess glue can flow back to the glue storage box 110 from the liquid infusion pipe 109.

[0032] Optionally, in the embodiment of the present application, the end of the scraper 105 is arranged close to the lower surface of the conveyor belt 102.

[0033] Optionally, in the embodiment of the present application, an infrared distance sensor is installed above the glue collecting hopper 106, and the infrared distance sensor is connected to the single-chip microcomputer through a data line, and the single-chip microcomputer is respectively connected to the delivery pump and the conveyor belt control unit through the data line, and the glue spraying unit 104 is connected to the delivery pump through a connecting pipe, and the delivery pump is connected to the glue storage unit through a connecting line. In actual use, the conveyor belt control unit controls the movement of the conveyor belt 102, and the movement of the conveyor belt 102 drives the pulp molded product to move. When the infrared distance sensor senses that the pulp molded product moves to the gluing position, the single-chip microcomputer issues a control command, and then the conveyor belt control unit stops running the conveyor belt 102. At the same time, the single-chip microcomputer controls the delivery pump to run, and then the glue in the glue storage unit is transported to the glue spraying unit 104, and the glue spraying unit 104 sprays the glue onto the pulp molded product, thereby realizing the automatic gluing function.

At the same time, when the conveyor belt 102 moves, the scraper 105 passes through The friction force scrapes off the glue liquid adhering to the lower surface of the conveyor belt 102, and it falls into the glue collecting bucket 106. At the same time, the guide ramp collects the glue liquid into the infusion tube 109. Then, the circuit on the electric heating tube 108 is turned on by the control switch. The electric heating tube 108 converts electrical energy into thermal energy and transmits the thermal energy to the infusion tube 109.
