Description

Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and particularly relates to a spraying mechanism. Background Art

[0002] Packaging materials refer to the materials used for manufacturing packaging containers, packaging decoration, packaging printing, packaging transportation, etc., which meet the requirements of product packaging.

[0003] Sterilization of packaging materials can be carried out by using sterilizing liquid or light sterilization. Among them, sterilization with sterilizing liquid can be divided into two methods: soaking and spraying. The spraying mechanism is a commonly used device for spraying sterilizing liquid. The spraying mechanism uses a nozzle to spray sterilizing liquid towards the packaging materials. In the spraying mechanism, multiple nozzles are often arranged on a spraying pipe. The nozzles far from the water inlet end often have insufficient spraying amount of sterilizing liquid due to insufficient water inlet pressure, resulting in incomplete sterilization. Summary of the Invention

[0004] Aiming at the disadvantages of poor spraying sterilization effect on packaging materials in the prior art, the utility model provides a spraying mechanism, which can ensure the spraying amount of the nozzles far from the liquid inlet end, thereby ensuring the sterilization effect.

[0005] The invention purpose of the utility model is realized by the following technical scheme: a spraying mechanism, including a water inlet pipe, several spraying pipes communicated with the water inlet pipe are arranged on the water inlet pipe, multiple nozzles are arranged on the spraying pipes along the length direction of the spraying pipes, and the inner diameter of the spraying pipe gradually decreases from the end close to the water inlet pipe to the other end.

[0006] Preferably, the number of the spraying pipes is an even number, and every two spraying pipes form a spraying unit. The two spraying pipes in the same spraying unit are parallel to each other, and the nozzles on the two spraying pipes are arranged oppositely.

[0007] Preferably, the spraying pipes are arranged horizontally and all the spraying pipes are located in the same plane, and the nozzles are arranged at the bottom of the spraying pipes.

[0008] Preferably, the central line of the nozzle is perpendicular to the central line of the spraying pipe, the central line of the nozzle is inclined relative to the vertical direction, and the spraying direction of the nozzle is inclined upwards.

[0009] Preferably, the nozzle includes a connecting pipe and a nozzle body. The connecting pipe is fixedly arranged on the spraying pipe, and the nozzle body is screwed to the connecting pipe.

[0010] Preferably, a nut is fixedly arranged on the nozzle body, and the central line of the nut coincides with the central line of the nozzle body.

[0011] Preferably, the opening of the nozzle is a V-shaped structure.

[0012] Preferably, a switch for controlling the opening and closing of the spraying pipe is provided on the spraying pipe, and the spray head and the water inlet pipe are respectively located on both sides of the switch.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In this application, through the structural optimization of the inner diameter of the spraying pipe, a better water pressure is also provided at the position far from the water inlet pipe, so that the spray heads far from the water inlet pipe can also have sufficient spraying pressure, thus ensuring the spraying sterilization effect;

[0015] 2. In the same spraying unit, the spray heads on different spraying pipes are arranged oppositely, so that the sterilizing liquid can be sprayed on both sides of the coil passing through the spraying unit at the same time, which can significantly improve the sterilization efficiency;

[0016] 3. The spraying direction of the spray head is inclined, which can make the spray head inclined relative to the conveying direction of the coil, so as to improve the flushing effect of the sprayed sterilizing liquid on the packaging material and is beneficial to flushing the dust on the surface of the packaging material.

[0022] The following further describes the utility model in conjunction with the embodiments shown in the drawings: Embodiment

[0023] As Figures 1 - 4As shown in the figure, a spraying mechanism includes a water inlet pipe 1. There are three spraying units 2 on the water inlet pipe 1. Each spraying unit 2 includes two spraying pipes 3 that are connected to the water inlet pipe 1 and are parallel to each other. There are six nozzles 4 arranged along the length direction of the spraying pipe 3. The nozzles 4 on the two spraying pipes 3 are arranged opposite to each other. The inner diameter of the spraying pipe 3 gradually decreases from the end close to the water inlet pipe 1 to the other end. The spraying pipes 3 are arranged horizontally and all the spraying pipes 3 are located in the same plane. The nozzles 4 are arranged at the bottom of the spraying pipes 3. The center line of the nozzle 4 is perpendicular to the center line of the spraying pipe 3. The center line of the nozzle 4 is inclined relative to the vertical direction and the spraying direction of the nozzle 4 is inclined upward. The number of spraying units 2 and the number of nozzles 4 can be adjusted according to the actual sterilization requirements of the packaging material.

[0024] The nozzle 4 includes a connecting pipe 5 and a nozzle 6. The connecting pipe 5 is fixedly arranged on the spraying pipe 3. The nozzle 6 is screwed to the connecting pipe 5. With this arrangement, the connection between the nozzle 6 and the connecting pipe 5 is detachable. When the nozzle 6 is blocked, it is convenient to repair or replace the nozzle 6. A nut 7 is fixedly arranged on the nozzle 6. The center line of the nut 7 coincides with the center line of the nozzle 6. A wrench can be used to turn the position of the nut 7, which is convenient for disassembling and assembling the nozzle 6. The opening of the nozzle 6 is of a V-shaped structure, which is convenient for the sterilization liquid sprayed by the nozzle 6 to spread, and can improve the spraying range of the nozzle 4.

[0025] A switch 8 for controlling the opening and closing of the spraying pipe 3 is arranged on the spraying pipe 3. The nozzle 4 and the water inlet pipe 1 are located on both sides of the switch 8 respectively. Whether the nozzle 4 works can be controlled through the switch 8.

[0026] In this application, in order to prevent the difference in pressure at different positions in the spraying pipe 3 from causing too large a difference in the flow rate of the sterilization liquid sprayed by each nozzle 4, the inner cavity of the spraying pipe 3 is designed to be conical. The water flow rate is smaller at the place in the inner cavity of the spraying pipe 3 that is farther away from the water inlet pipe 1, and the diameter is smaller at the place in the inner cavity of the spraying pipe 3 that is farther away from the water inlet pipe 1. In this way, the nozzles 4 far from the water inlet pipe 1 can also ensure the spraying volume. When this application is used, the end of the water inlet pipe 1 can be connected to a water pump (not shown in the drawings) and other structures for transporting the sterilization liquid into the water inlet pipe 1, so that the nozzles 4 can spray the sterilization liquid. When using this application to spray and sterilize the packaging material with the sterilization liquid, it is only necessary to make the packaging material pass between the two spraying pipes 3 in the spraying unit 2. The nozzles 4 on the two spraying pipes 3 can spray and sterilize the packaging material from both sides of the packaging material.
