Description

Technical Field

[0001] The invention belongs to the technical field of conveyor belt equipment, in particular to an antistatic and oil-resistant conveyor belt. Background Art

[0002] The conveyor belt is one of the important parts of the belt conveyor. It mainly realizes kinetic energy transfer and object transportation through friction. Due to the form of friction transmission, static electricity is easily generated. The conventional conveyor belt itself has a large resistance, which causes static electricity to accumulate on the surface of the conveyor belt. When transporting electronic devices and semiconductor materials, it is usually necessary to perform anti-static treatment on the surface of the conveyor belt.

[0003] In the antistatic treatment method of the conveyor belt, antistatic materials, conductive materials, and semiconductors are used to prepare antistatic coatings, and the coatings are coated and applied to the surface of the conveyor belt. After the charge is generated, the static charge can be conducted through the antistatic coating, and the static charge is dispersed or conducted to the ground, thereby avoiding the accumulation of static charge on the surface of the conveyor belt and reducing the probability of static breakdown when transporting objects.

[0004] The prior art discloses an antistatic PVC conveyor belt, with publication number CN1021985A. In this scheme, an antistatic agent coating and an antistatic coating layer are successively coated on the surface of the conveyor belt, and the conductive fibers, conductive resins, etc. contained in the coatings are utilized to reduce the surface impedance of the final conveyor belt, thereby avoiding the accumulation of a large amount of static charge. However, in actual application, it is found that during long-term use, when the coating on the surface of the conveyor belt is subjected to scratching and friction, the antistatic ability of the conveyor belt is easily weakened and the frequency of static electricity generation is increased. In view of this, the present invention proposes an antistatic and oil-resistant conveyor belt for solving the above-mentioned technical problems.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art.

[0016] The water vapor attachment assembly includes a water vapor box, a water tank and an ultrasonic atomizing nozzle;

[0017] The water vapor box is a cavity-type structure, and a through groove is formed on the water vapor box. The through groove is located on the movement path of the base belt, and the base belt extends to the inside of the water vapor box through the through groove.

[0018] A water tank is detachably mounted at the bottom of the water vapor box, an ultrasonic atomizing nozzle is mounted in the water vapor box, the ultrasonic atomizing nozzle extends into the water tank, and the ultrasonic atomizing nozzle draws water from the water tank and sprays it into the water vapor box after atomization.

[0019] Preferably, a brush is fixedly mounted on the steam box, and the brush is located on the movement path of the base belt. The brush is used to remove impurities on the surface of the modified sheet, and the modified sheet first contacts the brush and then enters the through groove.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 6 As shown, the antistatic and oil-resistant conveyor belt of the present invention comprises a base belt 1, and the base belt 1 is an annular structure;

[0037] It also includes a modification component, which is installed on the base belt 1 and is used to change the antistatic and oil-resistant properties of the surface of the base belt 1;

[0038] The modified component includes a modified sheet 2, a guide wire 21 and a connector 22;

[0039] The modified sheet 2 is installed on the surface of the base belt 1, and the surface of the modified sheet 2 is coated with an antistatic oil-resistant coating;

[0040] The modified sheet 2 is fixedly provided with uniformly distributed guide wires 21 in the length direction;

[0041] A connector 22 is fixedly mounted on the side of the modified sheet 2 that is not coated with the coating, and a connecting groove 23 is provided on the base belt 1, and the connecting groove 23 is engaged and connected with the connector 22;

[0042] When an antistatic and oil-resistant conveyor belt is used to transport objects, friction and scratches will occur between the objects and the surface of the conveyor belt. During long-term use, the surface coating of the conveyor belt may easily fall off or be damaged, thereby reducing the antistatic performance of the conveyor belt and increasing the probability of electrostatic breakdown during transportation. At this time, the conveyor belt itself is less damaged. In order to reduce the cost of maintaining the conveyor belt, it is usually necessary to re-spray the antistatic and oil-resistant coating to repair the antistatic and oil-resistant performance of the conveyor belt. Directly spraying the antistatic and oil-resistant coating on the entire conveyor belt not only requires disassembling the conveyor belt, but also the volume of the conveyor belt during spraying will hinder the spraying process. In the present invention, a modified component is provided on the base belt 1, and the loading and unloading of the base belt 1 and the modified component is utilized. When the antistatic and oil-resistant coating needs to be repaired, only the modified component needs to be removed and maintained without disassembling the conveyor frame structure.

[0043] Specifically, the modified component of the present invention is composed of a modified sheet 2, a guide wire 21 and a connecting piece 22, wherein the modified sheet 2 is a thin sheet structure with an antistatic oil-resistant coating sprayed on the surface, the guide wire 21 is embedded in the modified sheet 2, and the connecting piece 22 is fixedly installed on the modified sheet 2. When assembling the conveyor belt, the connecting piece 22 on the modified sheet 2 is aligned with the connecting groove 23 on the base belt 1, and the modified sheet 2 is fixed to the surface of the base belt 1 by the engagement of the connecting groove 23 and the connecting piece 22, and the guide wire 21 embedded in the modified sheet 2 connects the modified sheet 2 with the base belt. 1 is electrically connected. During the operation of the conveyor belt, the base belt 1 realizes transmission through friction, and static charge is generated on its surface. Since the base belt 1 itself has a high electrical impedance, the static charge is gathered on the base belt 1, and the modified sheet 2 is electrically connected to the base belt 1 through the guide wire 21, so that the static charge is conducted along the guide wire 21 to the antistatic oil-resistant coating on the surface of the modified sheet 2, thereby achieving the dispersion of the static charge and reducing the probability of static charge gathering. At the same time, during the operation of the conveyor belt, the static charge is finally conducted to the ground through the contact between the grounding wire and the conveyor belt.

[0044] The present invention arranges a modified sheet 2, sprays an antistatic oil-resistant coating on the modified sheet 2, and then installs the modified sheet 2 on the base belt 1 to form a conveyor belt together, so that the conveyor belt has a multi-layer structure. When maintaining the conveyor belt, it is only necessary to remove the modified sheet 2 on the surface of the conveyor belt and then perform re-spraying and other operations. Not only does it make the conveyor belt maintenance work simpler, but in the long-term use process, the conveyor belt can be refurbished by replacing the modified sheet 2, thereby effectively extending the service life of the conveyor belt.

[0045] As a preferred embodiment of the present invention, the modified sheets 2 are designed in plural, and two adjacent modified sheets 2 are provided with a snap-fit ​​groove 24 at one end close to each other. The two adjacent modified sheets 2 are connected end to end through the snap-fit ​​groove 24. By arranging multiple modified sheets 2, the multiple modified sheets 2 are snap-fitted and connected end to end through the snap-fit ​​groove 24, so that the surface of the base belt 1 can be fully covered, so that the base belt 1 and the modified sheets 2 are combined to form a conveyor belt. When used for a long time, when the surface coating of the local modified sheet 2 is damaged, it only needs to be removed for repair or replacement, thereby effectively reducing the difficulty of maintaining the conveyor belt and enhancing the convenience of conveyor belt maintenance.

[0046] As a preferred embodiment of the present invention, it also includes a water vapor attachment component, which cooperates with the base belt 1 and the modified sheet 2. The water vapor attachment component is used to eliminate the static charge on the base belt 1 and the modified belt. The water vapor attachment component includes a water vapor box 3, a water tank 31 and an ultrasonic atomizing nozzle 32. The water vapor box 3 is a cavity structure. A through groove 33 is opened on the water vapor box 3. The through groove 33 is located on the movement path of the base belt 1. The base belt 1 extends to the inside of the water vapor box 3 through the through groove 33. The water tank 31 is detachably installed at the bottom of the water vapor box 3. The water vapor box 3 is installed inside the water vapor box 3. An ultrasonic atomizing nozzle 32 is provided, and the ultrasonic atomizing nozzle 32 extends into the water tank 31. The ultrasonic atomizing nozzle 32 extracts water from the water tank 31, and sprays it into the water vapor tank 3 after atomization. It should be noted that in the present embodiment, the ultrasonic atomizing nozzle 32 at least includes a water pipe extending into the water tank 31, a water flow extraction and pumping component, and an ultrasonic atomizing component. After the ultrasonic atomizing nozzle 32 is started, it can automatically extract water from the water tank 31 and output water mist. In other embodiments of the present application, the ultrasonic atomizing nozzle 32 may also be other structures in the prior art that have water flow extraction and ultrasonic atomization injection.

[0047] During the use of the conveyor belt, in order to further enhance the conductivity of static charge, a water vapor attachment component is provided in the present invention. When the base belt 1 rotates under the drive of the driving device, the base belt 1 and the modified sheet 2 attached to the surface move synchronously. Since the through groove 33 provided on the water vapor box 3 is located on the movement path of the base belt 1, the base belt 1 and the modified sheet 2 enter the water vapor box 3 through the through groove 33. The ultrasonic atomizing nozzle 32 located inside the water vapor box 3 continuously extracts water from the water tank 31 and forms water mist under the action of ultrasonic oscillation. The water mist is sprayed and diffused in the water vapor box 3. During the movement of the base belt 1 and the modified sheet 2, water vapor is attached to the base belt 1 and the modified sheet 2. On the one hand, water is a conductor, and the presence of water vapor can effectively conduct and disperse the static charge gathered between the base belt 1 and the modified sheet 2. On the other hand, the attachment of water vapor increases the humidity on the surface of the conveyor belt, thereby effectively reducing the generation of frictional charging, thereby reducing the rate of static charge generation, and further enhancing the antistatic performance of the conveyor belt.

[0048] As a preferred embodiment of the present invention, a brush 4 is fixedly installed on the water vapor box 3, and the brush 4 is located on the movement path of the base belt 1. The brush 4 is used to remove impurities on the surface of the modified sheet 2, and the modified sheet 2 first contacts the brush 4 and then enters the through groove 33. The surface of the modified sheet 2 is cleaned by the brush 4, which can effectively reduce the adhesion of impurities on the modified sheet 2. On the one hand, it avoids the influence of impurities on the water vapor adhesion efficiency. On the other hand, during the long-term use of the conveyor belt, it can also effectively reduce the probability of the surface of the modified sheet 2 being scratched.

[0049] As a preferred embodiment of the present invention, the ultrasonic atomizing nozzle 32 is symmetrically designed, the gap between the base belt 1 and the modified sheet 2 is aligned with the output end of the ultrasonic atomizing nozzle 32, and a symmetrically designed guide sheet 5 is fixedly installed in the water vapor box 3. The guide sheets 5 are all triangular structures. The guide sheets 5 extend to the gap between the base belt 1 and the modified sheet 2. During the synchronous movement of the base belt 1 and the modified sheet 2, relative movement is generated between the base belt 1, the modified sheet 2 and the guide sheet 5. Under the obstruction of the guide sheet 5, the guide sheet 5 and the base belt 1 are in a state of being ... The gap of belt 1 is opened, and the ultrasonic atomizing nozzle 32 sprays water mist in the gap between base belt 1 and modified sheet 2. When base belt 1 and modified sheet 2 leave the range of guide sheet 5, base belt 1 and modified sheet 2 close again under the action of elasticity. At this time, the water mist filled between base belt 1 and modified sheet 2 can act as a coupling agent, so that the charge conduction ability between modified sheet 2 and base belt 1 is effectively enhanced, so that the static charge gathered on base belt 1 can be dispersed through water vapor and modified sheet 2, thereby enhancing the antistatic performance of the conveyor belt.

[0050] As a preferred embodiment of the present invention, a water mist groove 6 is provided on the side of the modified sheet 2 facing the base belt 1. The existence of the water mist groove 6 can fill more water mist in the gap between the modified sheet 2 and the base belt 1 when the water mist is sprayed and the modified sheet 2 and the base belt 1 are bonded again, and then the water mist is used to enhance the conductive performance of the modified sheet 2 and the base belt 1. The water mist grooves 6 on the multiple modified sheets 2 are connected at both ends, and the ultrasonic atomizing nozzle 32 extends into the water mist groove 6. During the continuous operation of the base belt 1 and the modified sheet 2, the ultrasonic atomizing nozzle 32 continuously sprays water mist into the water mist groove 6, and a part of the water mist The water mist diffuses in the water vapor box 3 through the gap between the base belt 1 and the modified sheet 2, so that the surfaces of the base belt 1 and the modified sheet 2 are evenly attached. Another part of the water mist flows through the water mist groove 6, so that after the modified sheet 2 and the base belt 1 are separated from the water vapor box 3, a certain amount of water mist can still be replenished through the water mist groove 6, thereby further enhancing the antistatic performance of the conveyor belt. It should be noted that, since the water mist in the present invention is generated by ultrasonic vibration, the particle size of the water after being atomized is about 5 microns. When the water mist is attached, a uniform water film is formed on the conveyor belt without generating obvious water droplets, and therefore the transported objects will not be wetted.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
