Description

Technical Field

[0001] The invention relates to the technical field of water-based adhesive coating, in particular to water-based adhesive coating equipment with a temperature control mechanism. Background Art

[0002] Water-based adhesive is a type of adhesive that uses water as a solvent. It is mainly used to enhance the bonding strength between various substrates and adhesive materials. It is widely used in construction, decoration, packaging and other fields. Water-based adhesive coating refers to applying the water-based adhesive evenly to the back of the substrate to enhance its bonding performance with the adhesive.

[0003] To complete the application of water-based adhesive, appropriate water-based adhesive coating equipment is required. To ensure the consistency of the water-based adhesive coating during use, the equipment is generally equipped with appropriate storage facilities. The ideal storage temperature for water-based adhesive is between 5°C and 35°C. Within this temperature range, the adhesive's performance and adhesion can be maintained at their optimal state. If the temperature is too low, the adhesive may freeze, causing its physical state to change and rendering it inoperable. If the temperature is too high, the moisture in the adhesive may evaporate too quickly, affecting its performance. Currently, most electric heating tubes are used to handle heating issues caused by low temperatures. This process can cause the temperature to gradually rise, easily exceeding the optimal storage temperature.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the water-based adhesive coating device with a temperature control mechanism not only improves the temperature control effect, but also improves the position adjustment capability and protection capability of the coating device;

[0016] (1) By assembling the temperature sensor inside the storage box, the driving motor is started to drive the stirring rod to rotate during storage, so as to improve the fluidity during storage. At the same time, the storage temperature is monitored by the temperature sensor. The annular cooling pipe is placed at the bottom of the storage box, and a hoop is set above the annular cooling pipe. The inner curvature of the hoop is adapted to the annular cooling pipe, so that the hoop can be just clamped on the outside of the annular cooling pipe, and is protected by a protective pad when in contact. And mounting plates are fixed on both sides of the hoop. After the hoop is assembled, the mounting plates are fixed to the bottom surface of the storage box with bolts. The temperature is monitored in real time by a temperature sensor, and the signal is converted and fed back to the control unit. The control unit receives the data of the temperature sensor, compares it with the preset temperature threshold, and sends a control signal to the relay when the temperature is low. After receiving the signal, the relay closes the circuit and turns on the power, and the electric heating tube is energized for heating. After the temperature is heated, the electric heating tube is stopped immediately after the temperature reaches the range, and cooling water is introduced at one pipe mouth to reach the position of the annular cooling pipe until the temperature drops to the appropriate range. The cooling water can be discharged at the other pipe mouth, thereby better improving the overall temperature control effect during the operation.

[0017] (2) By opening the first groove in the top of the bottom plate, the first electric push rod can push the guide column along the first rod body after it works, so as to change the left and right position of the shell. The shell itself is equipped with a servo motor, a screw, a slide and other components. Therefore, after the servo motor works, it can drive the screw to rotate. At this time, the screw and the slide cooperate with linear adjustment to change the front and back position of the processing table. When coating is required, the workpiece to be coated is placed on the table of the processing table. At this time, the second electric push rod can be started to push the clamping plate to move, and the clamping plate is used to clamp the workpiece. Then, the front and back, left and right positions of the processing table are adjusted according to the processing requirements to fully adapt to the spray pipe, thereby improving the overall adjustment ability;

[0018] (3) By fixing fixed columns on the top of the shell, there are two fixed columns in total, which are respectively located in the front and rear directions when the processing table moves linearly, and the front and rear end surfaces of the slide or processing table can fix the first baffle, and the second baffle is telescopically sleeved in the first baffle, and the tail end of the second baffle is fixed on the fixed column. Therefore, during the movement of the processing table, the two sets of first baffles and second baffles cooperate to extend and contract. When the first baffle and the second baffle in one direction cooperate to stretch to the maximum position, the processing table moves to the maximum displacement at this time, and at the same time, the other first baffle and the second baffle are fully recovered and compressed. The two sets of first baffles and the second baffle cooperate to shield the screw. Based on the design of the first curved surface and the second curved surface, the dripping colloid can be discharged to both sides along the first curved surface and the second curved surface, thereby improving the protection effect on the working of the screw.

Then, a threaded hole is provided in the slide for threaded connection with the screw 29. At the same time, the guide rod runs through the slide for limited sliding.

[0061] It should also be noted that in order to ensure the normal movement of the processing table 14, the processing table 14 and the entire area below it are located on the side of the support frame 4 without obstruction or restriction. At the same time, the empty space below the processing table 14 or the spray pipe 15 can be equipped with a position sensor to facilitate the acquisition of the position information of the processing table 14.

[0062] Working principle: First, place the workpiece to be coated on the table top of the processing table 14. At this time, the second electric push rod 24 can be started to push the clamp 31 to move, and the workpiece can be clamped by the clamp 31. Then, the front and back, left and right positions of the processing table 14 can be adjusted according to the processing requirements to fully adapt to the spray pipe 15. After starting the pump body 8, the water-based adhesive in the storage box 1 is extracted, and then drained through the first drainage pipe 18 to reach the position of the connecting valve 17 for adjusting the direction. After the connecting conduit 16 is connected to the spray pipe 15, the spray pipe 15 is used to carry out the coating work after the connecting conduit 16 diverts the flow.
