Description

Technical Field

[0001] The invention relates to the technical field of continuous feeding, in particular to a continuous feeding device for gypsum boards. Background Art

[0002] In the production process of building materials, gypsum board has become a key material for various building partition walls, ceilings and other structures due to its light weight, high strength, thinness, easy processing, and good sound insulation, heat insulation and fire resistance. With the vigorous development of the construction industry, more stringent requirements have been put forward for the output and quality of gypsum board, which requires continuous optimization and upgrading of each step in the production process. Among them, the feeding device is a key link in the start of production, and its performance directly affects the subsequent production efficiency and product quality.

[0003] At present, in the production of gypsum board, the importance of loading link is self-evident. The continuous loading device is responsible for stably and efficiently transporting the gypsum board to the subsequent processing procedures, accurately transferring it from the initial board stacking area to each key production station such as drying, cutting, and packaging.

[0004] During the continuous loading process, the roller often has a red spot phenomenon when conveying the gypsum board. The essence of this phenomenon is the insufficient friction between the roller surface and the gypsum board. It is impossible to ensure that the gypsum board is always in close contact with the roller during the conveying process, resulting in unstable board conveying. Summary of the invention

[0005] In view of the problems in the prior art, the present invention provides a continuous feeding device for gypsum board, and the specific technical scheme is as follows:

[0006] The continuous feeding device of the paper-faced gypsum board of the present application comprises:

[0007] Two side panels, both of which are vertically arranged and spaced apart;

[0008] Several transmission rollers, several groups of transmission rollers are rotatably arranged between two side plates and laid at equal distances along the length of the side plates;

[0009] and a bottom plate connected between the two side plates and arranged below the driving roller;

[0010] When the plate is transmitted, two adjacent transmission rollers can cooperate with the plate on the top and the bottom plate to form a sealed space, and a negative pressure space connected to the sealed space is arranged in the bottom plate.

[0011] As a further technical solution of the present invention, a negative pressure channel is opened in the bottom plate, and the negative pressure channel includes a main channel and several branch channels. One end of the main channel extends outward to form an opening and is connected to a negative pressure pump. The branch channels start from the main channel and extend into the sealed space.

[0012] As a further technical solution of the present invention, a recessed portion corresponding to the transmission roller is formed on the bottom plate, and a raised portion is formed between two adjacent recessed portions.

[0013] As a further technical solution of the present invention, the driving roller includes a roller body and a rubber sleeve wrapped around the roller body.

[0014] As a further technical solution of the present invention, the rubber sleeve is a wave-shaped structure in the circumferential direction, and the rubber sleeve includes alternating wave crest sections and wave trough sections, and there is a cavity between the wave crest section and the roller body.

[0015] As a further technical solution of the present invention, the recessed portion includes an inner concave area corresponding to the rubber sleeve and an outer concave area corresponding to the roller body; the inner diameter of the outer concave area is smaller than the inner diameter of the inner concave area

[0016] As a further technical solution of the present invention, it also includes a transmission assembly, which includes a plurality of sprockets and chains. The plurality of sprockets are respectively connected to one end of the transmission roller, and the plurality of sprockets are connected through chain transmission.

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) In the present application, a negative pressure space is formed between two adjacent transmission rollers, and the negative pressure space is used to provide an attraction to the board conveyed on the transmission roller. The attraction can make the gypsum board tightly adhere to the surface of the transmission roller, thereby increasing the positive pressure between the board and the transmission roller, thereby effectively preventing slipping and ensuring a stable feeding process; at the same time, the adsorption effect can also keep the gypsum board flat during the transportation process, reducing feeding interruptions or position deviations caused by shaking or offset.

[0019] (2) In the present application, a rubber sleeve with a corrugated structure is provided, and the corrugated structure increases the contact area between the rubber sleeve and the gypsum board. In addition, during the transportation process, the flexibility of the corrugated structure enables it to fit tightly against the transmission roller and the surface of the gypsum board. That is to say, even if there is a certain degree of unevenness on the surface of the board, it can effectively prevent outside air from entering the negative pressure space, maintain a stable negative pressure state, and reduce the shaking and deviation of the board.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Figure 1 The overall structural schematic diagram of the continuous feeding device of the gypsum board is shown; Figure 1 In the embodiment, the continuous feeding device of the paper-faced gypsum board comprises two side panels 100, a plurality of transmission rollers 200, a bottom plate 300 and a transmission assembly 400; the two side panels 100 are vertically arranged and arranged at intervals, a plurality of groups of transmission rollers 200 are rotatably arranged between the two side panels 100 and equidistantly laid along the length of the side panels 100, and the bottom plate 300 is connected between the two side panels 100 and arranged below the transmission rollers 200; when the plate is transmitted on the transmission rollers 200, the two adjacent transmission rollers 200 can cooperate with the plate on the top and the bottom plate 300 to form A sealed space 500, which is a negative pressure space, is used to provide an attraction to the board conveyed on the driving roller 200. The attraction can make the gypsum board tightly adhere to the surface of the roller, thereby increasing the positive pressure between the board and the driving roller 200. When the friction coefficient remains unchanged, the positive pressure increases and the friction force also increases, thereby effectively preventing slipping and ensuring a stable feeding process. At the same time, the adsorption effect can also keep the gypsum board flat during transportation, reducing feeding interruptions or position deviations caused by shaking or offset.

[0030] Figure 2 shows a schematic structural diagram of the base plate 300; Figure 2 In the figure, a recessed portion 310 corresponding to the driving roller 200 is opened on the bottom plate 300, and a protruding portion 320 is formed between two adjacent recessed portions 310; that is, along the length of the bottom plate 300, the recessed portions 310 and the protruding portions 320 are alternately arranged; the arrangement of the recessed portions 310 can ensure that the driving roller 200 can rotate, and can also ensure the sealing effect of the sealing space 500.

[0031] Figure 3 A schematic structural diagram of the negative pressure channel 330 is shown; Figure 4 The schematic diagram of the structure of the gypsum board during the transmission process is shown; Figure 3 and Figure 4 In the figure, a negative pressure channel 330 is opened in the bottom plate 300, and the negative pressure channel 330 includes a main channel 331 and a plurality of branch channels 332. One end of the main channel 331 extends outward to form an opening and is connected to the negative pressure pump; the branch channel 332 starts from the main channel 331 and extends into the sealed space 500. The branch channel 332 is used to connect the plurality of sealed spaces 500 to the main channel 331, thereby forcing the pressure in the sealed space 500 to decrease to form a negative pressure, so that the gypsum board is only attached to the transmission roller 200.

[0032] Figure 5 shows a schematic structural diagram of the transmission assembly 400; Figure 5 In the figure, the transmission assembly 400 includes a plurality of sprockets 410 and a chain 420, and the plurality of sprockets 410 are respectively connected to one end of the transmission roller 200, and the plurality of sprockets 410 are transmission-connected through the chain 420; all the sprockets 410 are transmission-connected together by the chain 420, and the sprocket 410 and the transmission roller 200 are coaxially connected so that the plurality of transmission rollers 200 rotate synchronously for conveying the paper-faced gypsum board; in actual use, the output end of the motor is transmission-connected to any sprocket 410 to provide power for the present application, which will not be elaborated herein.

[0033] Figure 6 A schematic structural diagram of the transmission roller 200 is shown; Figure 7 A schematic diagram of the structure of the peak section 221 and the trough section 222 is shown; Figure 6In the embodiment, the driving roller 200 includes a roller body 210 and a rubber sleeve 220 wrapped around the roller body 210; on the one hand, the rubber itself has a high friction coefficient. When the rubber sleeve 220 is wrapped around the surface of the roller body 210, the friction between the rubber sleeve 220 and the gypsum board can be significantly increased. When the gypsum board contacts the rubber, this high friction characteristic makes the board less likely to slip during transportation, thereby improving the stability of feeding; on the other hand, the rubber has good elasticity. During transportation, when it is arranged between the gypsum board and the driving roller 200, it can prevent the board from slipping. The material may have scratches, indentations and other defects on the surface due to hard collision; the rubber sleeve 220 is a corrugated structure in the circumferential direction, and the rubber sleeve 220 includes alternating crest sections 221 and trough sections 222, and there is a cavity between the crest section 221 and the roller body 210; the corrugated structure increases the contact area between the rubber sleeve and the paper-faced gypsum board, and during the transportation process, the ups and downs of the waveform can form a closer fit with the surface of the board; when the board moves on the rotating roller, the crest section 221 of the rubber sleeve 220 will produce more friction points with the surface of the board, further increasing the friction force and effectively preventing slipping. During the transportation process, the board will compress the rubber sleeve 220, forcing the rubber sleeve 220 to deform, that is, the peak section 221 is pressed toward the space where the trough section 222 is located, and the space inside the peak section 221 is compressed, giving the peak section 221 a larger deformation space. In other words, when the peak section 221 is compressed, it will have a larger contact area with the gypsum board; the flexibility of the waveform enables it to fit tightly against the drive roller 200 and the surface of the gypsum board. In other words, even if there is a certain degree of unevenness on the surface of the board, it can effectively prevent outside air from entering the negative pressure space, maintain a stable negative pressure state, and reduce the shaking and deviation of the board.

[0034] Figure 2 Combination Figure 7 The recessed portion 310 includes an inner recessed area 311 corresponding to the rubber sleeve 220 and an outer recessed area 312 corresponding to the roller body 210; the inner diameter of the outer recessed area 312 is smaller than the inner diameter of the inner recessed area 311; the outer recessed area 312 is used to ensure the sealing of the roller body 210 during partial rotation, while the inner recessed area 311 is used to realize the rotational sealing of the rubber sleeve 220, that is, it can ensure that the transmission roller 200 is sealed during the rotation process and maintain the sealing state of the sealing space 500.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
