Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carton production devices, in particular to auxiliary production equipment for waterproof cartons. Background Art
[0002] Waterproof cartons are specialized cartons designed to prevent water intrusion and protect their contents from moisture. Highly waterproof, they can withstand immersion in water without debonding, making them suitable for use in a variety of humidity environments, particularly high humidity conditions such as refrigerated and frozen storage. The manufacturing process for waterproof cartons involves spraying waterproof adhesive, waxing, and bonding waterproof plastic layers. Spraying waterproof adhesive is widely used in this field due to its relatively low cost, high quality, and high production efficiency.
[0003] In the prior art, the production method of spraying waterproof glue to prepare waterproof cartons is generally that an electric glue pump extracts the waterproof glue from the glue box and pressurizes it, and then enters the spray gun. The staff holds the spray gun and sprays the mist glue through the nozzle of the spray gun, and performs full coverage spraying on the surface of the carton board that has not been assembled into a carton. After spraying the glue, the carton board is dried by a drying equipment, and then the carton board is processed into a finished waterproof carton. Although the existing production method of spraying waterproof glue to prepare waterproof cartons meets production needs to a certain extent, it is limited by equipment and still has the following technical disadvantages. Specifically, since the staff holds the spray gun and approaches the carton board to spray glue, after spraying one end of the carton board, the staff is also required to turn the carton board over (spraying glue on the original lower side). The above-mentioned manual operation method will bring inconvenience to the staff and increase production costs. More importantly, because the staff is too close to the spraying point for a long time, the staff will breathe in the harmful components in the glue, which will more or less have an adverse effect on their health. Utility Model Content
[0004] In order to overcome the drawbacks of the existing production method of preparing waterproof cartons by spraying waterproof glue, which exists in the manual glue spraying operation on the carton board due to the lack of a practical equipment, the utility model provides an auxiliary production equipment for waterproof cartons under the joint action of relevant mechanisms. The staff only needs to clamp the two sides of the carton board to a fixed work station, and the nozzle can automatically move back and forth and left and right to spray glue on the entire surface of the carton board. After the upper end of the carton board is sprayed, the staff can rotate the lower end of the carton board to the upper end to continue the glue spraying operation through a simple power switch operation, thereby bringing convenience to the staff and correspondingly improving the work efficiency.

The control circuit includes three time controllers W2, W3, and W4 and power switches AS2, S3, and S5, connected via circuit board wiring. The power input pins 1 and 2 of the power switches AS2 and AS5 are connected in series with the power input pins 1 and 2 of the three time controllers W2, W3, and W4 via power switch AS3. The handles of power switches AS2, AS3, and AS5, and power switches S, S1, and S4 are located outside the front opening of component box 8.

Power module W1's power output terminal 3 is connected to the power input terminals of pressure switch T and power switch S4 via wires. Power module W1's power output terminals 3 and 4 are connected to the control circuit's power input terminal, time controller W4, and power switches S and S1's power input terminals 1 and 2, respectively, via wires. The power output terminal of the first power switch S4, the power output terminal of pressure switch T, and the negative power output terminal 4 of power module W1 are connected to the power input terminals of the two solenoid valves DC1 and DC2, respectively, via wires. Power output terminals 3, 4, and pins 5, 6 of the second and third power switches S1 are connected to the positive and negative, and negative and positive, power input terminals of the motor reducers M of the two electric linear slides M1 and the two electric clamping and flipping mechanisms, respectively, via wires.

[0019] Figure 1-Figure 2 As shown in FIG, after AC 220V power enters the power input terminal of power module W1, pins 3 and 4 of power module W1 output stable DC 24V power to the control circuit and power switch S as well as the power input terminals of S1, S4, and S3. Before operation, the left and right sides of the carton board to be glued are fixedly clamped horizontally in the clamping jaws 41 of two sets of electric clamping and flipping mechanisms. Then, multiple manual bolts 42 are tightened to start the glue spraying operation (the carton board is in a horizontal state). The staff can adjust the height of the carton board as needed. After turning the handle of the power switch S1 to the left or right, the 1 and 2 pins and the 3 and 4 pins or the 5 and 6 pins of the power switch S1 are connected respectively. In this way, the positive and negative or negative and positive power input terminals of the two sets of electric linear slides M1 will be energized. After the positive and negative power input terminals of the two sets of electric linear slides M1 are energized, their sliding blocks will drive the carton board to an upward height. After the negative and positive power input terminals of the two sets of electric linear slides M1 are energized, their sliding blocks will drive the carton board to a lower height. After the height is reached, turn off the power switch S1, so that the carton board is located at a suitable position at the lower end of the nozzle 1 (the purpose of adjusting the height can also make the clamps 41 of the two sets of electric clamping and flipping mechanisms drop in height before and after spraying, so as to facilitate the flipping of the carton board).
[0020] Figure 1-Figure 2As shown, when the pressure in glue tank 2 falls below a certain level (e.g., below 0.1 MPa), the internal contacts of pressure switch T close, energizing the solenoid valve DC2 and opening the valve core, allowing compressed air from the air compressor to enter glue tank 2. When the pressure in glue tank 2 rises above a certain level (e.g., above 0.1 MPa), the internal contacts of pressure switch T open, de-energizing the valve core of solenoid valve DC2 and closing the valve core, preventing compressed air from entering the glue tank. This allows the new system to maintain a constant pressure in the glue tank during operation, with the high-pressure compressed air driving the glue out through the nozzle at the lower end of nozzle 1. When the operator turns on power switch S4, solenoid valve DC1 opens, and the pressurized air in glue tank 2 drives the glue inside through flexible hose 7 and into the inlet hose 6. The glue is then sprayed downward through the nozzle of the nozzle in a mist-like form. The process for this automatic spraying system is as follows (turn on power switch AS3). (1) Pins 3 and 4 of the time controller W2 output 8 seconds of power (time adjustable) to the positive and negative power input terminals of the electric linear slide M3. Then, the electric linear slide M3 drives the spray gun head to move from left to right to spray glue on the upper end surface of the carton board. (2) Pins 3 and 4 of the time controller W4 (time adjustable) output 3 seconds of power to the positive and negative power input terminals of the two sets of electric linear slides M2. Then, the electric linear slide M2 drives the spray gun head to move from front to back to the right to the next spraying point to spray glue on the upper end surface of the carton board and the back side of the sprayed surface. (3) The time controller W3 (time adjustable) outputs 8 seconds of power from its 3rd and 4th pins to the positive and negative power input terminals of the electric linear slide M3, so that the electric linear slide M3 drives the spray gun head to move from right to left to spray glue on the upper end surface of the carton board; (4) The time controller W4 (time adjustable) outputs 3 seconds of power from its 3rd and 4th pins to the positive and negative power input terminals of the two sets of electric linear slides M2, so that the electric linear slide M2 drives the spray gun head to move from front to back to the right to the next spraying point to continue spraying glue on the upper end surface of the carton board and the back side of the sprayed surface. (5) The above processes (1) to (4) are continuously circulated, and the mist glue sprayed by the nozzle can automatically spray glue on the front, back, left and right of the carton board surface.(6) After the glue spraying is completed on the upper surface of the carton board, the staff turns off the power switch AS3. After the staff turns the handle of the power switch S1 to the right, the negative and positive power input terminals of the two sets of electric linear slides M1 are energized and their sliding blocks will drive the carton board to descend. After the height is reached, the power switch S1 is turned off. Then, the staff can turn the handle of the power switch S to the left or right by hand, and the 1, 2 feet and 3, 4 feet or 5, 6 feet of the power switch S are connected respectively. In this way, the positive and negative or negative or positive terminals of the motor reducer M of the two sets of electric clamping and flipping mechanisms are connected. The positive and negative power input terminals of the two motor reducers M are energized, and the shafts thereof drive the carton board to rotate clockwise and flip over. The shafts thereof drive the carton board to rotate counterclockwise and flip over. When the lower side of the carton board flips to the level of the upper side, the power switch S is turned off. The staff member turns the handle of the power switch S1 to the left, and when the negative and positive power input terminals of the two electric linear slides M1 are energized, the sliding blocks thereof drive the carton board to rise to a certain height. When the height is reached, the power switch S1 is turned off. (7) The staff member turns on the power switch AS2, and the negative and positive power input terminals of the two electric linear slides M2 are energized, and the sliding blocks thereof drive the electric linear slide M3 and the nozzle to move forward to the stop point, and then the power switch AS2 is turned off (and the power switch AS5 is turned on, and the negative and positive power input terminals of the electric linear slide M3 are energized, and the sliding blocks thereof drive the nozzle to move to the left stop point, and then the power switch AS4 is turned off). (8) Turn on the power switch AS3, and the glue spraying operation can be carried out on the original lower side end (now located at the upper end) of the carton board in the same manner as the above (1) to (4). This new type brings convenience to the staff and correspondingly improves work efficiency.
