Description

Technical Field

[0001] This invention relates to the field of conveyor belt cleaning technology, and more specifically to a gypsum board forming belt cleaner. Background Technology

[0002] Currently, gypsum board is typically shaped on a forming conveyor belt. A shaping roller is positioned above the belt, and the gypsum board is shaped by passing between the belt and the roller to achieve the desired thickness. During the shaping process, a hydration reaction occurs within the gypsum slurry. Excess water from this reaction exists in a free state within the gypsum board and overflows onto the forming conveyor belt during transport. Some existing forming conveyors are made of black rubber. The excess water from the hydration reaction adheres to the belt under the heat released during the reaction, dissolving with the black rubber on the belt surface to produce a black, viscous stain that easily contaminates the facing paper during transport.

[0003] Therefore, the existing method of using forming belts and shaping rollers to shape and transport gypsum boards has the problem that free water may react with the black rubber material under the action of heat to produce black and sticky stains, which can easily stain the protective paper. Summary of the Invention

[0004] The purpose of this invention is to provide a gypsum board forming belt cleaner to solve the technical problem in the prior art where free water may react with the black rubber material under the action of heat to produce black and sticky stains, which easily stain the protective paper.

[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0006] A gypsum board forming belt cleaner, comprising:

[0007] A cleaning mechanism is provided below the conveyor belt. The cleaning mechanism is equipped with a roller brush, which can clean the dirt on the surface of the conveyor belt.

[0008] A rinsing mechanism having a nozzle and a cleaning brush, wherein the nozzle is capable of spraying cleaning fluid onto the roller brush, and the cleaning brush is installed at the lower end of the roller brush and contacts the surface of the roller brush.

[0009] The rinsing mechanism sprays cleaning fluid onto the roller brush through the nozzle. The cleaning fluid can cover the surface of the conveyor belt with the roller brush to dissolve the stains. The roller brush cleans the dissolved stains and rolls to contact the cleaning brush to brush off the wastewater. It then rotates and circulates to brush the conveyor belt.

[0010] A drying mechanism is used to dry the surface of the conveyor belt to remove water stains from the surface of the conveyor belt.

[0011] In a preferred embodiment of the present invention, the cleaning mechanism is provided with a bracket, and the roller brush is mounted on the bracket. The bracket can support the roller brush to abut against the conveying surface of the conveyor belt.

[0012] As a preferred embodiment of the present invention, the roller brush has a brush sweeping roller frame and a brush sweeping belt. The brush sweeping roller frame is mounted on the bracket and has a plurality of brush sweeping rollers. The brush sweeping belt is mounted around the brush sweeping rollers.

[0013] The roller brush rotates in the opposite direction to the conveyor belt, and the brush has bristles on its surface.

[0014] In a preferred embodiment of the present invention, the rinsing mechanism has a rinsing groove, which is mounted on the bracket and located at the lower end of the roller brush. The nozzle is mounted on the upper end of one side of the rinsing groove, and the cleaning brush is disposed inside the rinsing groove.

[0015] When the nozzle sprays the cleaning fluid, the overflowing cleaning fluid and the cleaning fluid squeezed out by the roller brush can flow downward into the rinsing tank.

[0016] In a preferred embodiment of the present invention, the return section of the roller brush passes through the rinsing tank, the cleaning brush is installed at the bottom of the rinsing tank, and the shape of the cleaning brush matches the bottom shape of the roller brush, with both ends of the cleaning brush extending to the opening of the rinsing tank.

[0017] The cleaning brush contacts the surface of the brush belt. After the brush belt sweeps, it rotates back into the rinsing tank, where it can contact the cleaning brush to remove the stains from the surface of the brush belt and dissolve the stains with the cleaning solution.

[0018] As a preferred embodiment of the present invention, a liquid storage tank is provided on one side of the rinsing tank, a liquid pump is installed on the liquid storage tank, and the nozzle is connected to the liquid pump through a pipe to pump cleaning liquid through the liquid pump;

[0019] The nozzle of the spray head faces the upper end of the roller brush, is close to the downstream of the conveyor belt in the conveying direction, and its spraying direction is the opposite of the conveyor belt running direction, so as to repeatedly spray cleaning liquid to wet the roller brush after it has been brushed by the cleaning brush.

[0020] As a preferred embodiment of the present invention, four lifting cylinders are installed below the bracket, and the four lifting cylinders can drive the bracket to lift and adjust.

[0021] The lifting cylinder can raise the bracket so that the roller brush contacts the conveyor belt surface upward, or lower the bracket so that the roller brush leaves the conveyor belt surface.

[0022] As a preferred embodiment of the present invention, the drying mechanism includes a drying air duct and a hot air blower. The blower is installed below the drying air duct and can blow hot air into the drying air duct. The drying air duct is installed below the conveyor belt and can rectify the hot air so that the hot air is evenly blown onto the surface of the conveyor belt.

[0023] The drying mechanism is installed downstream of the cleaning mechanism along the direction of the conveyor belt.

[0024] As a preferred embodiment of the present invention, the drying air duct runs vertically through the interior and has an inclined guide plate inside. The air outlet of the hot air blower is connected to the air inlet installed at the lower end of the drying air duct, and the air outlet of the drying air duct faces the surface of the conveyor belt.

[0025] The guide plate is inclined in the opposite direction to the conveyor belt's conveying direction.

[0026] As a preferred embodiment of the present invention, the drying air duct is provided with an upward-facing soft brush at the end near the downstream end of the conveyor belt in the conveying direction. The soft brush contacts the surface of the conveyor belt and is used to brush away the floating dust on the surface of the conveyor belt.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] This invention, by setting up a roller brush and a nozzle, allows the nozzle to spray cleaning liquid onto the roller brush, thereby wetting the roller brush. The roller brush then cleans the conveyor belt by rolling. While brushing and softening the stains, the cleaning liquid can fully contact the stains, thereby emulsifying and dissolving the sticky components of the stains, thus achieving a thorough cleaning of the conveyor belt.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1 As shown, the present invention provides a gypsum board forming belt cleaner, including a sweeping mechanism 1, a rinsing mechanism 2, and a drying mechanism 3. The following will provide further explanation in conjunction with specific embodiments:

[0039] The cleaning mechanism 1 is located below the conveyor belt and is equipped with a roller brush 11, which can clean the dirt on the surface of the conveyor belt.

[0040] The relative movement between the conveyor belt and the roller brush 11 brushes off softened stains. However, softened stains from the rubber belt tend to adhere to the surfaces of both the conveyor belt and the roller brush 11. Direct brushing can further contaminate the conveyor belt surface and cause some stains to accumulate on the roller brush 11. Therefore, a cleaning solution is needed to dissolve the stains, such as existing specialized alkaline or solvent-based belt cleaners, which can emulsify or dissolve the grease and sticky components in the stains, reducing the probability of stains adhering to the conveyor belt. Therefore, the following solution is provided.

[0041] In this embodiment, as Figure 2 As shown, the rinsing mechanism 3 has a nozzle 21 and a cleaning brush 22. The nozzle 21 can spray cleaning fluid onto the roller brush 11, and the cleaning brush 22 is installed at the lower end of the roller brush 11 and contacts the surface of the roller brush 11.

[0042] The rinsing mechanism 3 sprays cleaning fluid onto the roller brush 11 through the nozzle 21. The cleaning fluid can cover the surface of the conveyor belt 1 with the roller brush 11 to dissolve the stains. The roller brush 11 cleans the dissolved stains and rolls to contact the cleaning brush 22 to brush off the sewage. It then rotates and circulates to brush the conveyor belt 1.

[0043] The roller brush 11 is moistened by the nozzle 21, and the sewage containing dissolved stains is brushed off by the cleaning brush 22 after cleaning. When dissolving stains, a certain reaction time is usually required. Therefore, it is necessary to extend the contact time between the cleaning solution and the softened stains to improve the dissolving effect.

[0044] like Figure 2 As shown, the cleaning mechanism 1 is provided with a bracket 12, and the roller brush 21 is installed on the bracket 12. The bracket 12 can support the roller brush 21 to abut against the conveying surface of the conveyor belt.

[0045] The roller brush 11 has a brush roller frame 111 and a brush belt 112. The brush roller frame 111 is mounted on the bracket 12. The brush roller frame 111 has a plurality of brush rollers 113. The brush belt 112 is mounted around the brush rollers 113.

[0046] The roller brush 11 rotates in the opposite direction to the running direction of the conveyor belt 1, and the surface of the brush belt 112 has bristles.

[0047] Specifically, the brush and sweeping belt 112 is supported by the brush and sweeping roller 113 to form a conveyor belt-type cleaning device. Compared with conventional cylindrical rollers, it can effectively increase the contact area and contact time between the roller brush 11 and the conveyor belt.

[0048] In addition, the drive device for the brush roller 113 can be set on the side of the bracket 12, such as a motor and a drive belt connecting the machine shaft and the roller shaft. The motor is installed on one side of the bracket 12 and drives the connecting machine shaft and the roller shaft through the drive belt.

[0049] During the brushing process, the pressure between the brushing belt 112 and the conveyor belt may cause the cleaning fluid to overflow. When the cleaning brush 22 brushes the roller brush 11, it may also cause the cleaning fluid to overflow. Therefore, in order to collect the cleaning fluid and avoid pollution of the working environment, the following preferred embodiment is provided.

[0050] like Figure 2 As shown, the rinsing mechanism 2 has a rinsing tank 23, which is mounted on the bracket 12 and located at the lower end of the roller brush 11. The nozzle 21 is mounted on the upper side of the rinsing tank 23, and the cleaning brush 22 is disposed inside the rinsing tank 23.

[0051] When the nozzle 21 sprays the cleaning fluid, the overflowing cleaning fluid and the cleaning fluid squeezed out by the roller brush 11 can flow downward into the rinsing tank 23.

[0052] The return section of the roller brush 11 passes through the rinsing tank 23. The cleaning brush 22 is installed at the bottom of the rinsing tank 23, and the shape of the cleaning brush 22 matches the bottom shape of the roller brush 11. The two ends of the cleaning brush 22 extend to the opening of the rinsing tank 23.

[0053] The cleaning brush 22 contacts the surface of the brush belt 112. After the brush belt 112 brushes, it rotates back into the rinsing tank 23, where it can contact the cleaning brush 22 to brush off the stains on the surface of the brush belt 112 and dissolve the stains with the cleaning solution.

[0054] The cleaning solution can be collected through the rinsing tank 23 to avoid contamination. In order to ensure the dissolving effect, the cleaning solution is usually in excess. The cleaning solution accumulated at the bottom of the rinsing tank 23 is in an unsaturated state. When the brush belt 112 brushes the stains, some stains may stick to the brush bristles due to the pressure. Therefore, the return section below the roller brush 11 can dissolve the sticky stains a second time through the unsaturated cleaning solution. Together with the cleaning brush 22, the stains are brushed off. After the roller brush 11 leaves the liquid surface, the wastewater is removed by the side pressure of the cleaning brush 22. After the roller brush 11 leaves the rinsing tank 23, most of the stains can be removed, ensuring the subsequent cleaning effect.

[0055] In addition, the surface of the roller brush 11 may not be fully wetted with cleaning fluid at the beginning of brushing, and there may not be enough cleaning fluid in the rinsing tank 23. Therefore, cleaning fluid can be pre-wetted at the bottom of the rinsing tank 23 to make it easier for the nozzle 21 to replenish the cleaning fluid. Furthermore, in order to prevent the cleaning fluid from overflowing in the rinsing tank 23, a drain port can be opened at the upper end of the side wall of the rinsing tank 23, and a sewage tank can be set to collect sewage. The height of the drain port should ensure that the return section of the roller brush 11 can be submerged in the rinsing fluid.

[0056] The degree of compression between the cleaning brush 22 and the roller brush 11 can be manually determined to ensure the brushing effect. After compression, the roller brush 11 needs to be replenished with cleaning fluid. Therefore, the spraying work of the nozzle 21 should be carried out after the cleaning brush 22 has been squeezed and brushed. Therefore, the following preferred embodiment is provided.

[0057] like Figure 2 As shown, a liquid storage tank 211 is provided on one side of the rinsing tank 23. A liquid pump 212 is installed on the liquid storage tank 211. The nozzle 21 is connected to the liquid pump 212 through a pipe so that the cleaning liquid can be pumped by the liquid pump 212.

[0058] The nozzle 21 faces the upper end of the roller brush 11, close to the downstream of the conveyor belt 1 in the conveying direction, and its spraying direction is the opposite of the running direction of the conveyor belt 1, so as to repeatedly spray cleaning liquid to wet the roller brush 11 after it has been brushed by the cleaning brush 22.

[0059] After passing the cleaning brush 22, the cleaning fluid in the storage tank 211 of the roller brush 11 is pumped to the nozzle 21 by the liquid pump 212 and sprayed out, thereby wetting the roller brush 11.

[0060] During the process of conveying and molding gypsum board, depending on the intensity of the hydration reaction, softened black stains will usually appear on the conveyor belt after several hours or days of conveying. Normal conveyor belts will also be damaged when in contact with cleaning liquid for a long time. Therefore, in this embodiment, it is necessary to rinse and brush the softened stains when they are found, and maintain the normal operation of the conveyor belt after cleaning.

[0061] In this embodiment, such as Figure 2 As shown, four lifting cylinders 211 are installed below the bracket 12, and the four lifting cylinders 121 can drive the bracket 12 to be raised and lowered for adjustment.

[0062] The lifting cylinder 121 can raise the bracket 12 so that the roller brush 11 contacts the surface of the conveyor belt 1 upwards, or lower the bracket 12 so that the roller brush 11 leaves the surface of the conveyor belt 1.

[0063] When softened stains appear, the support 12 can be raised by the lifting cylinder 121 so that the roller brush 11 can contact the conveyor belt. After brushing is completed, the support 12 can be lowered by the lifting cylinder 121 to separate the roller brush 11 from the conveyor belt. At the same time, the roller brush 11 and the liquid pump 212 can be turned off.

[0064] The conveyor belt surface is relatively damp after brushing. If it is not dried, it may cause dirt to accumulate on the gypsum board paper and may even seep back into the gypsum board, disrupting the hydration process. Therefore, in this embodiment, if... Figure 3 As shown, the drying mechanism 3 includes a drying air duct 31 and a hot air blower 32. The blower 32 is installed below the drying air duct 31 and can blow hot air into the drying air duct 31. The drying air duct 31 is installed below the conveyor belt 1 and can rectify the hot air so that the hot air is evenly blown onto the surface of the conveyor belt 1.

[0065] The drying mechanism 3 is installed downstream of the cleaning mechanism 2 along the running direction of the conveyor belt 1.

[0066] The drying air duct 31 runs vertically through the interior and has an inclined guide plate 311 inside. The air outlet of the hot air blower 32 is connected to the air inlet installed at the lower end of the drying air duct 31. The air outlet of the drying air duct 31 faces the surface of the conveyor belt 1.

[0067] The guide plate 311 is inclined in the opposite direction to the conveyor belt 1. In addition, water from the gypsum board may remain when the conveyor belt is working normally, so the hot air fan 32 can be turned on to dry the conveyor belt as needed.

[0068] The hot air can be uniformly delivered to the surface of the conveyor belt through the hot air blower 32 and the drying air duct 31, thereby drying the conveyor belt.

[0069] The droplets on the conveyor belt surface may contain suspended particles, which can easily form floating dust on the conveyor belt surface after drying. In this embodiment, such as... Figure 3 As shown, an upward-facing soft brush 33 is provided at the downstream end of the drying duct 3 near the conveyor belt 1 in the conveying direction. The soft brush 33 contacts the surface of the conveyor belt 1 and is used to brush away the floating dust on the surface of the conveyor belt. After drying, the soft brush 33 can brush away the floating dust and keep the surface of the conveyor belt flat.

[0070] In this embodiment, when softened stains appear, the support 12 is raised by the lifting cylinder 121 so that the upper surface of the roller brush 11 comes into contact with the conveyor belt. The roller brush 11 and the liquid pump 212 are turned on, and the nozzle 21 sprays out cleaning liquid to wet the roller brush 11. After the upper surface of the roller brush 11 brushes the conveyor belt, it moves downward to the rinsing tank 23. The cleaning brush 22 brushes and squeezes the roller brush 11 to squeeze out the sewage on the roller brush 11. After the surface of the roller brush 11 leaves the cleaning brush 22, it can be wetted again by the nozzle 21 and repeatedly brushes the conveyor belt. After the conveyor belt passes the roller brush 11, it runs to the drying mechanism 3. The drying air duct 31 rectifies and delivers the hot air from the hot air fan 32 to the surface of the conveyor belt for drying. After drying, the surface of the conveyor belt is brushed by the soft brush 33. After cleaning, the support 12 is lowered by the lifting cylinder 121 to separate the roller brush 11 and the conveyor belt, and the roller brush 11 and the liquid pump 212 are turned off.

[0071] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
