Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a surface coating equipment for antistatic corrugated cardboard boxes. Background Technology

[0002] In the existing technology, the coating process of antistatic corrugated boxes refers to covering the surface of corrugated cardboard with a layer of conductive coating material, so that it has the ability to dissipate static electricity. The purpose of coating is to enhance the antistatic properties of corrugated cardboard boxes, prevent problems such as spark discharge and dust adsorption caused by static electricity accumulation, and make the surface of corrugated cardboard boxes glossy and beautiful, making them convenient to sell.

[0003] In existing technologies, coating of corrugated cardboard boxes is generally performed while the box is still in its cardboard state. This makes coating more convenient and efficient. After coating, the cardboard needs to be dried and cured to ensure coating stability and prevent subsequent dust accumulation or damage. The common curing method in existing technologies is hot air convection drying. However, hot air convection drying has obvious drawbacks: the area with the strongest airflow often has the highest temperature, resulting in uneven drying. In addition, the distance between the air outlet and the cardboard means that heat transfer is not direct. Therefore, an improved surface coating equipment for anti-static corrugated cardboard boxes is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a surface coating device for antistatic corrugated cardboard boxes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface coating device for antistatic corrugated cardboard boxes, comprising a fixed frame, wherein a coating device for coating corrugated cardboard boxes is provided on one side inside the fixed frame, the coating device comprising a first coating roller and a second coating roller, the first coating roller being movably mounted on one side inside the fixed frame via a bearing, the second coating roller being movably mounted on the first coating roller inside the fixed frame via a rotating shaft, and a drying mechanism for rapidly drying and curing coatings being provided on one side of the fixed frame, the drying mechanism comprising a drying roller and a heating sleeve, the drying roller being movably mounted on one side inside the fixed frame via a bearing, and the heating sleeve being fixedly mounted inside the drying roller, wherein the heating sleeve of this device is simply a conductor with high resistance, which can be heated by current when energized, and the drying roller is provided with a power supply mechanism for supplying power to the heating sleeve.

[0006] Preferably, the power supply mechanism includes a conductive ring, a sliding groove, a conductive chamber, a graphite electrode, and a conductive sheet. Conductive rings are fixedly installed at both ends of the drying roller. A sliding groove is provided on one side of the conductive ring on the inner sidewall of the fixed frame. A conductive chamber is movably installed inside the sliding groove via a slider. A graphite electrode is movably engaged inside the conductive chamber. A conductive sheet is fixedly installed on the outer side of the conductive chamber. The graphite electrode is connected to the conductive chamber and the conductive sheet via an electrical wire. Since this device utilizes a continuously rotating drying roller and a heating sleeve to heat, dry, and cure the coating, rotational power supply is required. The power supply mechanism of this application is designed to meet the need for rotating power supply to the heating sleeve. The device uses graphite electrodes tightly attached to the outer surface of the conductive rings, thus connecting the two conductive rings and the heating sleeve in series. Power is supplied to the continuously rotating heating sleeve simply by applying voltage through the conductive sheet and the two graphite electrodes, thereby meeting the heating and drying requirements of the heating sleeve.

[0007] Preferably, a spring is fixedly installed on one side of the slide groove, and one end of the spring is fixedly connected to the conductive chamber. The spring can push the conductive chamber to move so that the graphite electrode can be tightly attached to the outer surface of the conductive ring. The graphite electrode of this device is a consumable and will gradually wear down with the use of the device. The spring can ensure that the graphite electrode can still be attached to the conductive ring after it wears down. When the graphite electrode wears down to its limit, the conductive chamber is pushed to move inside the slide groove so that the conductive chamber is away from the conductive ring, and then a new graphite electrode can be inserted and removed.

[0008] Preferably, a transfer roller is movably disposed inside the fixed frame between the second coating roller and the drying roller via a bearing. The transfer roller can play an auxiliary role in the transfer, ensuring that the paperboard can be correctly transferred into the drying roller.

[0009] Preferably, there are two first coating rollers arranged symmetrically at the top and bottom. A first storage box is fixedly installed inside the fixed frame at the lower end of the first coating rollers. The first storage box can be used to store the coating material required for antistatic coating. The lower end of the first coating rollers is immersed in the coating material in the first storage box. In this way, as the first coating rollers rotate, the coating work can be completed on the lower end of the cardboard passing between the two first coating rollers.

[0010] Preferably, there are two second coating rollers arranged symmetrically at the top and bottom. Inside the fixed frame, a first material transfer roller is movably mounted on one side of the upper second coating roller via a bearing. The outer surface of the second coating roller is in contact with the outer surface of the first material transfer roller. Inside the fixed frame, a second material transfer roller is movably mounted on one side of the first material transfer roller via a rotating shaft. The outer surfaces of the first material transfer roller and the second material transfer roller are in contact with each other. Inside the fixed frame, a second material storage box is provided at the lower end of the second material transfer roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. After coating, the cardboard can be directly placed between the drying rollers. The drying rollers generate heat through the internal heating sleeve. The cardboard is then dried, cured, and shaped by the method of bonding the cardboard with the heating rollers. The heating roller drying method has good bonding and uniform heating area. Unlike hot air drying, the main area blown by the airflow will have a high temperature. This results in a good drying and curing effect and improves product quality.

[0012] 2. This utility model utilizes a continuously rotating drying roller and a heating sleeve to heat, dry, and cure the coating. This requires a rotating power supply, and the power supply mechanism in this application is designed to meet the need for powering the rotating heating sleeve. The device uses graphite electrodes tightly attached to the outer surface of the conductive rings, thus connecting the two conductive rings and the heating sleeve in series. Power can be supplied to the continuously rotating heating sleeve simply by applying voltage through the conductive sheet and the two graphite electrodes, thereby meeting the heating and drying requirements of the heating sleeve.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a surface coating device for antistatic corrugated cardboard boxes, including a fixed frame 1. A coating device for coating corrugated cardboard boxes is installed on one side inside the fixed frame 1. The coating device includes a first coating roller 2 and a second coating roller 3. The first coating roller 2 is movably mounted on one side inside the fixed frame 1 via a bearing. The second coating roller 3 is movably mounted on the first coating roller 2 inside the fixed frame 1 via a rotating shaft. A drying mechanism for rapidly drying and curing the coating is provided on one side of the fixed frame 1. The drying mechanism includes a drying roller 4 and a heating sleeve 5. The drying roller 4 is movably mounted on one side inside the fixed frame 1 via a bearing. The heating sleeve 5 is fixedly mounted inside the drying roller 4. The heating sleeve 5 in this device is simply a conductor with high resistance; it can be heated by applying current. The drying roller 4 is equipped with a power supply mechanism to supply power to the heating sleeve 5.

[0017] The power supply mechanism includes a conductive ring 6, a sliding groove 7, a conductive chamber 8, a graphite electrode 9, and a conductive sheet 10. Conductive rings 6 are fixedly installed at both ends of the drying roller 4. A sliding groove 7 is provided on one side of the conductive ring 6 on the inner sidewall of the fixed frame 1. A conductive chamber 8 is movably installed inside the sliding groove 7 via a slider. A graphite electrode 9 is movably engaged inside the conductive chamber 8. A conductive sheet 10 is fixedly installed on the outer side of the conductive chamber 8. The graphite electrode 9 is connected to the conductive chamber 8 and the conductive sheet 10 by an electrical wire. Since this device uses a continuously rotating drying roller 4 and a heating sleeve 5 to heat, dry, and cure the coating, rotational power supply is required. The power supply mechanism in this application is designed to meet the need for rotating power supply to the heating sleeve 5. The device uses graphite electrodes 9 tightly attached to the outer surface of the conductive rings 6, thus connecting the two conductive rings 6 and the heating sleeve 5 in series. Power is supplied to the continuously rotating heating sleeve 5 simply by applying voltage through the conductive sheet 10 and the two graphite electrodes 9, thereby meeting the heating and drying requirements of the heating sleeve 5. A spring 11 is fixedly installed on one side of the slide groove 7. One end of the spring 11 is fixedly connected to the conductive chamber 8. The spring 11 can push the conductive chamber 8 to move so that the graphite electrode 9 can be tightly attached to the outer surface of the conductive ring 6. The graphite electrode 9 of this device is a consumable and will gradually wear down with the use of the device. The spring 11 can ensure that the graphite electrode 9 can still be attached to the conductive ring 6 after it wears down. When the graphite electrode 9 wears down to its limit, the conductive chamber 8 is pushed to move inside the slide groove 7 so that the conductive chamber 8 is away from the conductive ring 6, and then a new graphite electrode 9 can be inserted and removed. Inside the fixed frame 1, a transfer roller 12 is movably arranged between the second coating roller 3 and the drying roller 4 via bearings. The transfer roller 12 can play an auxiliary role in the transfer, ensuring that the paperboard can be correctly transferred into the drying roller 4. There are two first coating rollers 2, which are arranged symmetrically at the top and bottom. A first storage box 13 is fixedly installed inside the fixed frame 1 at the lower end of the first coating rollers 2. The first storage box 13 can be used to store the coating required for antistatic coating. The lower end of the first coating rollers 2 is immersed in the coating in the first storage box 13. Thus, as the first coating rollers 2 rotate, the coating work can be completed on the lower end of the cardboard passing between the two first coating rollers 2. Two second coating rollers 3 are provided, arranged symmetrically vertically. Inside the fixed frame 1, a first transfer roller 14 is movably mounted on one side of the upper second coating roller 3 via a bearing. The outer surface of the second coating roller 3 is in contact with the outer surface of the first transfer roller 14. Inside the fixed frame 1, a second transfer roller 15 is movably mounted on one side of the first transfer roller 14 via a shaft. The outer surfaces of the first transfer roller 14 and the second transfer roller 15 are in contact with each other. The fixed frame 1 is located at the lower end of the second transfer roller 15. A second storage box 16 is provided (the second storage box 16 and the first storage box 13 store the same antistatic coating). The first coating roller 2 of this device is responsible for coating the lower end of the cardboard, while the second coating roller 3 is responsible for coating the upper end of the cardboard. In order to ensure that the second coating roller 3 can be continuously supplied with coating and to prevent coating leakage and waste, the first transfer roller 14 and the second transfer roller 15 are used to supply the coating inside the second storage box 16 to the outer surface of the second coating roller 3 by rotation.

[0018] Working principle: When using this device, the cardboard that needs to be coated with antistatic coating passes through the first coating roller 2, the second coating roller 3, the transfer roller 12, and the drying roller 4 in sequence. The first coating roller 2 can coat the lower end of the cardboard, while the second coating roller 3 is responsible for coating the upper end of the cardboard. After coating, the cardboard can directly enter the drying roller 4. At this time, the drying roller 4 generates heat through the internal heating sleeve 5, and then uses the heating roller to adhere to the cardboard for drying, curing and shaping. The heating roller drying method has good adhesion and uniform heating area, unlike hot air drying, where the temperature of the main area blown by the airflow is high. Thus, the drying and curing effect is good, improving product quality. This device utilizes a continuously rotating drying roller 4 and a heating sleeve 5 to heat, dry, and cure the coating. This requires a power supply for rotation, and the power supply mechanism in this application is designed to meet the need for powering the heating sleeve 5. The device uses graphite electrodes 9 tightly attached to the outer surface of the conductive rings 6, thus connecting the two conductive rings 6 and the heating sleeve 5 in series. Power can be supplied to the continuously rotating heating sleeve 5 simply by applying voltage through the conductive sheet 10 and the two graphite electrodes 9, thereby meeting the heating and drying requirements of the heating sleeve 5.
