Description

Technical Field

[0001] The present invention relates to the technical field of paper conveying equipment, and more specifically, to a paper conveying device and a gypsum board production system. Background Art

[0002] Paper-faced gypsum board is a lightweight building board made of gypsum board and facing paper as the main raw materials, mixed with water, foaming agent, coagulant, starch, fiber and other auxiliary materials. It has the characteristics of thermal insulation, light weight, sound insulation, fire resistance, good decorative performance, convenient construction, space saving, energy saving and environmental protection.

[0003] In the production process of gypsum board, the mixer discharges the gypsum slurry evenly onto the lower face paper of the vibrating platform and enters the molding machine, where the gypsum board of the required specifications is squeezed out. The upper and lower face papers are bonded at the edges of the gypsum board by adhesive glue, and then solidified on the solidification belt conveyor. During the gypsum board forming and solidification process, the face paper at different positions of the gypsum board has different water absorption, and the pre-expansion effect of the face paper is poor, resulting in uneven adhesion between the face paper and the gypsum board, resulting in small ripples, unevenness, and poor appearance quality of the gypsum board surface after forming. Summary of the invention

[0004] An embodiment of the present application provides a paper conveying device and a gypsum board production system. The paper conveying device of the present application includes a paper storage component, a water spray component and a paper picking component. The water spray component is used to spray water onto the paper. The paper storage function of the paper storage component can extend the pre-expansion time of the paper and water, ensuring uniform pre-expansion of the paper, thereby reducing the corrugation and unevenness of the board surface after the paper and the board are combined.

[0005] The technical solution of the embodiment of the present application is as follows:

[0006] A paper conveying device, comprising:

[0007] The paper storage assembly comprises a plurality of conveying rollers which are spaced apart from each other, and the plurality of conveying rollers are arranged to allow the paper to pass through in sequence;

[0008] a water spray assembly, arranged on the upstream side of the paper storage assembly along the conveying direction of the paper, and configured to spray water onto the paper; and

[0009] The paper picking assembly is located at the downstream side of the paper storage assembly along the conveying direction of the paper.

[0010] The technical effects of the paper conveying device of the embodiment of the present application are as follows:

[0011] The paper conveying device provided by the embodiment of the present application has a paper conveying direction starting from the water spraying component, passing through the paper storage component and transmitting to the paper picking component; the water spraying component can be used to spray water on the paper, so that the paper is wetted to achieve the effect of pre-expansion of the paper; the multiple conveying rollers of the paper storage component are arranged to allow the paper to bypass in sequence, so that the paper storage component plays the role of storing paper; the water spraying component is arranged on the upstream side of the paper storage component, and through the paper storage function of the paper storage component, the pre-expansion time of the paper and water can be extended, so that the paper is pre-expanded by water more evenly and the pre-expansion effect of the paper is better. Therefore, after the uniformly pre-expanded paper passes through the paper picking component, it can be relatively flatly attached to the plate, reducing the corrugation and unevenness of the plate surface after the plate and paper are combined.

[0012] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0019] Please refer to the attached Figure 1 To Attachment Figure 4 The structure diagram of the paper conveying device 100 of the embodiment of the present application is shown in FIG. Figure 1The embodiment of the present application shown provides a paper conveying device 100, including a paper storage assembly 1, a water spray assembly 2 and a paper pickup assembly 3. The paper storage assembly 1 includes a plurality of conveying rollers 11 distributed at intervals, and the plurality of conveying rollers 11 are configured to allow the paper 4 to pass through in sequence; along the conveying direction of the paper 4, the water spray assembly 2 is disposed on the upstream side of the paper storage assembly 1, and the water spray assembly 2 is configured to spray water on the paper 4; along the conveying direction of the paper 4, the paper pickup assembly 3 is located on the downstream side of the paper storage assembly 1.

[0020] Specifically, Figure 1 In the paper conveying device 100 shown, the conveying direction of the paper 4 is from the water spraying component 2, through the paper storage component 1 to the paper picking component 3. The paper conveying device 100 of the embodiment of the present application is arranged to include a water spraying component 2 and a paper storage component 1 on the upstream side of the paper picking component 3; the water spraying component 2 can be used to spray water on the paper 4, so that the paper 4 is wetted to achieve the effect of pre-expansion of the paper; the multiple conveying rollers 11 of the paper storage component 1 are arranged to allow the paper 4 to bypass in sequence, so that the paper storage component 1 plays the role of storing the paper 4; the water spraying component 2 is arranged on the upstream side of the paper storage component 1, and through the paper storage function of the paper storage component 1, the pre-expansion time of the paper 4 and water can be extended, so that the paper 4 is pre-expanded by water more evenly, and the pre-expansion effect of the paper 4 is better. Thus, after the uniformly pre-expanded paper 4 passes through the paper picking component 3, it can be relatively flatly attached to the board, reducing the corrugation and unevenness of the board surface after the paper 4 and the board are combined.

[0021] In an exemplary embodiment, Figure 1 As shown, a plurality of conveying rollers 11 are arranged into two rows, namely a first conveying roller group 12 and a second conveying roller group 13. The first conveying roller group 12 and the second conveying roller group 13 each include one conveying roller 11 or a plurality of conveying rollers 11 distributed at intervals. The conveying rollers 11 in the first conveying roller group 12 and the second conveying roller group 13 are parallel to each other and staggered.

[0022] The conveying rollers 11 in the first conveying roller group 12 and the second conveying roller group 13 are respectively arranged to allow the paper sheets 4 to pass around alternately in sequence, so that the paper sheets 4 are bent in a serpentine shape.

[0023] Specifically, the paper storage assembly 1 includes a first conveying roller group 12 and a second conveying roller group 13. The conveying rollers 11 in the first conveying roller group 12 and the second conveying roller group 13 are parallel to each other and staggered. The conveying rollers 11 in the first conveying roller group 12 and the second conveying roller group 13 are respectively arranged to allow the paper 4 to bypass alternately in sequence, so that the paper 4 is in a serpentine and circuitous shape. In this way, the paper 4 can be stored relatively flatly and regularly, so that the paper 4 output from the paper storage assembly 1 is relatively neat, the capacity for storing paper 4 is large, and it is also convenient for the arrangement and installation of the conveying rollers 11.

[0024] It is understood that the paper storage assembly 1 of the embodiment of the present application is not limited to Figure 1 The structural form shown.

[0025] In an exemplary embodiment, Figure 1 As shown, the paper storage assembly 1 also includes a support member 14, which includes a first support member 141 and a second support member 142. The first support member 141 and the second support member 142 are arranged opposite to each other, the first conveying roller group 12 is installed to the first support member 141, and the second conveying roller group 13 is installed to the second support member 142.

[0026] Specifically, the support member 14 is used to install and fix the conveying roller 11 .

[0027] In an exemplary embodiment, Figure 1 As shown, the support member 14 also includes a third support member 143 , the two ends of which are respectively connected to one end of the first support member 141 and the second support member 142 close to the water spray assembly 2 , and the water spray assembly 2 is installed to the side of the third support member 143 away from the conveying roller 11 .

[0028] Specifically, the third support member 143 has the function of installing and fixing the water spray assembly 2, so that the water spray assembly 2 is installed on the upstream side of the paper storage assembly 1. The third support member 143 is also used to connect and support the first support member 141 and the second support member 142. Figure 1 In the illustrated embodiment, the ends of the first support member 141 and the second support member 142 that are away from the water spray assembly 2 are also connected to a support member so as to stably and firmly fix the conveying roller 11 on the support member 14 .

[0029] In an exemplary embodiment, Figure 1 As shown, the water spray assembly 2 includes an atomizing device, which is configured to spray atomized water toward the paper 4 , and the sprayed atomized water can cover the width range of the paper 4 .

[0030] Specifically, the atomized water sprayed by the water spray assembly 2 can cover the width range of the paper 4. As the paper 4 is transported and moved, the entire range of the paper 4 passing through the water spray assembly 2 can be evenly wetted, so that the pre-expansion treatment of the paper 4 is more uniform.

[0031] In an exemplary embodiment, Figure 1 and Figure 2As shown, the paper picking assembly 3 includes a paper stabilizing assembly 31, which includes a driving device 311, a plurality of redirecting rollers 312, a first transmission member 313 and a second transmission member 314. The plurality of redirecting rollers 312 are configured to allow the paper 4 output from the paper storage assembly 1 to bypass in sequence, and the plurality of redirecting rollers 312 are connected via the second transmission member 314; the driving device 311 is connected to a redirecting roller 312 via the first transmission member 313, and is configured to drive the plurality of redirecting rollers 312 to rotate via the second transmission member 314 to convey the paper 4.

[0032] Specifically, Figure 2 The embodiment of the paper pickup assembly 3 shown includes three redirecting rollers 312, and the three redirecting rollers 312 are connected together by a second transmission member 314. It can be understood that the paper pickup assembly 3 of the embodiment of the present application can also include other numbers of redirecting rollers 312, and the second transmission member 314 and the first transmission member 313 can be designed as a chain or belt structure. Figure 1 As shown, the driving device 311 is connected to a redirecting roller 312 through a first transmission member 313, so that the driving device 311 can drive the redirecting roller 312 to rotate, and the redirecting roller 312 can drive other redirecting rollers 312 to rotate through a second transmission member 314, thereby achieving the purpose of synchronously rotating multiple redirecting rollers 312 to transport the paper 4. Figure 1 As shown, the paper picking assembly 3 may include a bracket, and the driving device 311 and the plurality of redirecting rollers 312 may be arranged to be mounted on the bracket.

[0033] It is worth noting that the paper picking assembly 3 transports the paper 4 according to a certain distribution position through multiple redirecting rollers 312, which can increase the friction between the paper 4 and the redirecting rollers 312 during the transportation of the paper 4, ensure the stable transmission of the paper 4, and reduce the corrugation and unevenness of the board surface after the paper 4 is combined with the board.

[0034] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the paper stabilizing assembly 31 also includes a pressure roller assembly 315, which cooperates with a redirecting roller 312 located on the downstream side along the conveying direction of the paper 4 among the multiple redirecting rollers 312, so that the paper 4 is output from between the pressure roller assembly 315 and the redirecting roller 312.

[0035] Specifically, the paper 4 is transported from between the pressure roller assembly 315 and a redirecting roller 312 located on the downstream side of the transport direction of the paper 4 among the plurality of redirecting rollers 312, so that the transport operation of the paper 4 can be stabilized. Figure 1 As shown, the pressure roller assembly 315 can cooperate with a redirecting roller 312 at the end of the downstream side of the conveying direction of the paper 4, which is beneficial to ensure the stable transmission of the paper 4. Figure 2As shown, the pressure roller assembly 315 can be configured to include a roller, a roller mounting seat, a connecting rod, etc. The paper picking assembly 3 can be configured to include a bracket, and the pressure roller assembly 315 is mounted to the bracket.

[0036] In an exemplary embodiment, Figure 1 and Figure 3 As shown, the paper picking assembly 3 further includes a speed measuring assembly 32 , which is configured to measure the conveying speed of the paper 4 so as to control the driving device 311 according to the conveying speed of the paper 4 .

[0037] Specifically, the speed measuring component 32 measures the conveying speed of the paper 4 and feeds back to the driving device 311, and the driving device 311 reasonably adjusts and controls the output driving force of the driving device 311 according to the actual conveying speed of the paper 4. In this way, the paper 4 can be conveyed more smoothly and stably, so that the corrugation and unevenness of the board surface after the board and the paper 4 are combined are less; the conveying speed of the paper 4 can also be adjusted to ensure that the conveying speed of the paper 4 matches the speed of the subsequent board production line.

[0038] In an exemplary embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the speed measuring component 32 includes a rocker arm 321, a counterweight 322, a swing conveying roller 323 and a measuring component 324. The counterweight 322 and the swing conveying roller 323 are respectively installed on both sides of the swing center 3211 of the rocker arm 321. The swing conveying roller 323 is configured to allow the paper 4 output from the paper stabilizing component 31 to bypass.

[0039] The measuring component 324 is configured to measure the swing angle of the swing rod 321 .

[0040] Specifically, the swing conveying roller 323 has the function of conveying the paper 4. Figure 1 As shown, as the transmission speed of the paper 4 fluctuates, the swing rod 321 can also swing around the swing center 3211, so that the swing rod 321 can drive the swing conveying roller 323 to swing to Figure 1 The measuring component 324 measures the swing angle of the swing rod 321, thereby obtaining the swing change of the swing rod 321, and indirectly obtaining the change of the transmission speed of the paper 4, so that the measuring component 324 can feed back the change of the transmission speed of the paper 4 to the driving device 311, so as to adjust the output driving force of the driving device 311, thereby changing the transmission speed of the paper 4 and stabilizing the transmission operation of the paper 4.

[0041] In an exemplary embodiment, Figure 3 and Figure 4As shown, the measuring component 324 includes an angular displacement sensor 3241, a third transmission member 3242 and a measuring member 3243. The measuring member 3243 is installed to the swing center 3211 of the pendulum 321 and swings synchronously with the pendulum 321. The angular displacement sensor 3241 and the measuring member 3243 are connected through the third transmission member 3242 to measure the swing angles of the measuring member 3243 and the pendulum 321.

[0042] Specifically, the angle position sensor 3241 swings and rotates synchronously with the measuring member 3243 and the rocker arm 321 through the third transmission member 3242. The angle position sensor 3241 measures the angle change of its own swinging rotation, and derives the swing angle change of the rocker arm 321 and the transmission speed deformation of the paper 4.

[0043] It is understandable that the measuring assembly 324 of the present application can also be configured in other structural forms. The third transmission member 3242 can be configured in a structural form such as a chain or a belt.

[0044] In an exemplary embodiment, Figure 3 and Figure 4 As shown, one end of the swing rod 321 is provided with a long first through hole 3212 extending along the length direction of the swing rod 321, the swing conveying roller 323 is installed to the first through hole 3212 through a first support shaft 3231, and the position of the first support shaft 323 in the first through hole 3212 is set to be slidably adjustable; and / or

[0045] The other end of the swing rod 321 is provided with a second strip-shaped through hole 3213 extending along the length direction of the swing rod 321 , the counterweight 322 is installed to the second through hole 3213 through a second support shaft 3221 , and the position of the second support shaft 3221 in the second through hole 3213 is set to be slidably adjustable.

[0046] Specifically, the swing conveying roller 323 and the counterweight 322 are both configured to be able to adjust their positions along the long strip hole extending in the length direction of the swing rod 321, so that when one side of the counterweight 322 of the swing rod 321 swings downward, the counterweight 322 can slide along the second through hole 3213 in a direction away from the swing center 3211, and the swing conveying roller 323 can slide in a direction close to the swing center 3211, thereby accelerating the swing speed of the swing rod 321. Similarly, when one side of the swing conveying roller 323 of the swing rod 321 swings downward, the swing conveying roller 323 can slide along the first through hole 3212 in a direction away from the swing center 3211, and the counterweight 322 can slide in a direction close to the swing center 3211, thereby accelerating the swing speed of the swing rod 321.

[0047] It can be seen that the above structural design of the speed measuring component 32 can make the swing arm 321 of the present application swing more sensitively and quickly as the transmission speed of the paper 4 changes. This structural design is conducive to the measuring component 324 to quickly measure the change of the swing angle of the swing arm 321.
