DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1

[0030] A papermaking machine with adjustable pulp concentration, such as Figure 1-Figure 4As shown, it includes a base 1, a mounting frame 2, a slurry mixing cylinder 3, a closing plate 31, a drying conveyor 4, a liquid storage mechanism 5 and an adjusting mechanism 6. The mounting frame 2 is bolted to the rear of the base 1, the slurry mixing cylinder 3 is bolted to the upper part of the mounting frame 2, the front part of the lower side of the slurry mixing cylinder 3 is connected with a closing plate 31 through a bearing, a torsion spring is connected between the closing plate 31 and the slurry mixing cylinder 3, the front part of the base 1 is bolted to the drying conveyor 4, the drying conveyor 4 is located on the lower side of the closing plate 31, a liquid storage mechanism 5 is provided on the left part of the base 1, the liquid storage mechanism 5 can store clean water, the liquid storage mechanism 5 is provided with an adjusting mechanism 6, and the adjusting mechanism 6 can adjust the water supply to change the slurry concentration.

[0031] When using the device, the clean water used to dilute the pulp is stored through the liquid storage mechanism 5, and then the staff puts the pulp into the pulp mixing tube 3. After placing it, the staff controls the water in the liquid storage mechanism 5 to flow into the pulp mixing tube 3 through the regulating mechanism 6, and adjusts the water intake into the pulp mixing tube 3 according to the required dilution degree. After a certain amount of water enters the pulp mixing tube 3, the staff controls the water in the liquid storage mechanism 5 to stop conveying through the regulating mechanism 6, and the pulp and water are mixed into slurry in the pulp mixing tube 3. Then the staff opens the closing plate 31, the torsion spring is deformed, and the slurry in the pulp mixing tube 3 flows into the drying conveyor 4 for papermaking. When the slurry in the pulp mixing tube 3 flows out, the staff pushes the closing plate 31 to rotate upward and close, and the torsion spring is reset.

[0032] like Figure 1 and Figure 3 As shown, the liquid storage mechanism 5 includes a support plate 51, a liquid storage cylinder 52 and a water outlet pipe 53. The support plate 51 is installed on the left part of the base 1 by bolts, and the liquid storage cylinder 52 is bolted on the upper part of the support plate 51. The liquid storage cylinder 52 can store clean water for diluting pulp. The upper rear part of the liquid storage cylinder 52 is connected to a water inlet pipe, and the water outlet pipe 53 is connected between the right side of the liquid storage cylinder 52 and the left side of the pulp mixing cylinder 3.

[0033] like Figure 2 and Figure 4 As shown, the adjustment mechanism 6 includes a guide block 61, a baffle 62, a connecting plate 63 and an electric push rod 64. The guide block 61 is welded to the front right side of the liquid storage cylinder 52, and the baffle 62 is slidably connected to the guide block 61. The rear part of the baffle 62 blocks the left side of the water outlet pipe 53. The electric push rod 64 is bolted to the upper right side of the liquid storage cylinder 52, and the connecting plate 63 is welded to the extended end of the electric push rod 64. The lower part of the connecting plate 63 is connected to the baffle 62.

[0034] When using the device, the staff guides clean water into the liquid storage cylinder 52 through the water inlet pipe for storage. After the pulp is put into the pulp mixing cylinder 3, the staff controls the electric push rod 64 to extend. The extension of the electric push rod 64 drives the connecting plate 63 to move forward. The connecting plate 63 moves forward and drives the baffle 62 to slide forward on the guide block 61. After the baffle 62 slides forward, it no longer blocks the left side of the water outlet pipe 53. At this time, the clean water in the liquid storage cylinder 52 can flow into the pulp mixing cylinder 3 through the water outlet pipe 53 to dilute the pulp. When the pulp in the pulp mixing cylinder 3 is diluted to a suitable concentration, the staff controls the electric push rod 64 to shorten. The shortening of the electric push rod 64 drives the connecting plate 63 to move backward. The connecting plate 63 moves backward and drives the baffle 62 to slide backward and re-block the left side of the water outlet pipe 53, thereby stopping the addition of water to the pulp mixing cylinder 3. In this way, the concentration of the pulp in the pulp mixing cylinder 3 can be adjusted as needed.

[0035] Example 2

[0036] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes a suction mechanism 7, which can suck pulp. The suction mechanism 7 includes a mounting seat 71, a suction pump 72, a suction pipe 73, an arc plate 74 and a suction frame 75. The mounting seat 71 is installed on the right part of the base 1 by bolts, and a suction pump 72 is bolted on the upper part of the mounting seat 71. The suction pump 72 can provide power for sucking pulp. The front side of the suction pump 72 is connected to a suction pipe 73, and the suction pipe 73 can transport the pulp into the pulp mixing cylinder 3. The left part of the suction pipe 73 is located above the rear part of the pulp mixing cylinder 3. An arc plate 74 is welded on the right part of the base 1, and a suction frame 75 is welded on the upper part of the arc plate 74. The right end of the suction pipe 73 is connected to the suction frame 75.

[0037] When the device is used, pulp is transported from an external conveying device to the device, and then the staff starts the suction pump 72. The suction pump 72 operates to suck air, and the pulp on the external conveying device is sucked into the suction pipe 73 through the arc plate 74. The pulp is transported into the pulp mixing tube 3 through the suction pipe 73. After a certain amount of pulp is sucked, the staff turns off the suction pump 72. In this way, the pulp can be automatically transported into the pulp mixing tube 3.

[0038] like Figure 1 and Figure 6 As shown, it also includes a mixing mechanism 8, which can mix the slurry. The mixing mechanism 8 includes a driving motor 81 and a stirring rod 82. The driving motor 81 is bolted to the front upper part of the slurry mixing cylinder 3, and the stirring rod 82 is connected to the output shaft of the driving motor 81. The stirring rod 82 can mix the slurry, and the stirring rod 82 is located in the slurry mixing cylinder 3.

[0039] When using the device, after a certain amount of clean water enters the slurry mixing tube 3, the staff starts the drive motor 81. The output shaft of the drive motor 81 rotates to drive the stirring rod 82 to rotate. The rotation of the stirring rod 82 can stir the slurry in the slurry mixing tube 3, so that the clean water and pulp are mixed more evenly. When the slurry is mixed evenly, the staff turns off the drive motor 81.

[0040] like Figure 1 and Figure 7 As shown, a protective mechanism 9 is also included, which can prevent foreign matter from entering the slurry mixing cylinder 3. The protective mechanism 9 includes a guide rod 91, a protective plate 92 and a handle 93. The guide rod 91 is welded to the left rear part of the upper side of the slurry mixing cylinder 3, and a protective plate 92 is slidably connected to the guide rod 91. The protective plate 92 can shield and protect the inside of the slurry mixing cylinder 3, and a handle 93 is welded to the left rear part of the protective plate 92.

[0041] When it is necessary to absorb pulp, the staff pushes the handle 93 to move backward, and the handle 93 moves backward to drive the protective plate 92 to slide backward on the guide rod 91. After the protective plate 92 slides backward, the pulp mixing tube 3 is opened. At this time, the suction pipe 73 can transport the pulp into the pulp mixing tube 3. When the pulp is added, the staff pushes the handle 93 to move forward. The handle 93 moves forward to drive the protective plate 92 to slide forward to block the upper side of the pulp mixing tube 3, thereby preventing foreign matter from entering the pulp mixing tube 3 during pulp mixing and affecting the pulp quality.

[0042] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a pulling mechanism 10, which can automatically open the closing plate 31. The pulling mechanism 10 includes a pulling plate 101, a rotating plate 102 and a cross bar 103. The pulling plate 101 is welded to the left front part of the protective plate 92, the rotating plate 102 is welded to the lower side of the closing plate 31, and the cross bar 103 is welded to the rotating plate 102. The front end of the pulling plate 101 contacts the left part of the cross bar 103.

[0043] When the device is used, the protective plate 92 slides backward and drives the pulling plate 101 to move backward. The pulling plate 101 moves backward and squeezes the cross bar 103 to move backward. The cross bar 103 moves backward and drives the rotating plate 102 to rotate backward. The closing plate 31 rotates downward and opens accordingly, and the torsion spring is deformed. When the slurry flows out, the staff can check the outflow of the slurry through the upper side of the slurry mixing cylinder 3. When the protective plate 92 slides forward, the pulling plate 101 moves forward accordingly and no longer squeezes the cross bar 103. Under the action of the torsion spring resetting, the closing plate 31 rotates upward and closes accordingly. In this way, the closing plate 31 can be automatically opened for discharging while the protective plate 92 is opened.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
