Description

Technical Field

[0001] This utility model relates to the field of coated white-faced kraft paper production technology, specifically to a coated white-faced kraft paper production equipment. Background Technology

[0002] Coated white-faced kraft paper is increasingly becoming a widely used packaging material due to its high strength, high single-sided whiteness, and good printability. It is mainly used to make high-end cardboard boxes, and its production technology is relatively advanced compared to other packaging materials.

[0003] The fibers used in the production of coated white-faced kraft paper need to be pulped. Unpulped fibers are stiff, have poor interlacing power, and are not usable. Pulping can improve the hydrophilicity and plasticity of the fibers and improve the quality of the paper. After pulping, the degree of freeness of the pulp needs to be tested.

[0004] Chinese utility model patent CN215678394U discloses a device for detecting the pulp beating effect in the production of white-faced kraft paper. It can directly observe the pulp quality. However, during sampling, on the one hand, the sampling tubes at different positions will obtain pulp at different heights in the water tank; on the other hand, the sampling tubes at different positions will leave the pulp surface at different times, resulting in different pulp contents in each sampling tube during testing. Ultimately, this leads to errors in the test results and low accuracy. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a production equipment for coating white-faced kraft paper, which can more accurately detect the beating degree of the pulp.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a production equipment for coating white-faced kraft paper, including a water tank, and further comprising:

[0007] A support assembly, comprising a horizontal plate and two support plates, wherein the horizontal plate is disposed above the water tank and the two support plates are disposed on the ground and respectively fixedly connected to both ends of the horizontal plate;

[0008] A lifting assembly includes a vertical pole, a top plate, a movable plate, a lead screw, and a motor. The vertical pole is fixedly mounted longitudinally on the horizontal plate, the top plate is fixedly mounted on the top of the vertical pole, the movable plate is disposed on the vertical pole and slidably connected to the vertical pole, the lead screw passes longitudinally through the movable plate and is threadedly connected to the movable plate, and both ends of the lead screw are rotatably connected to the top plate and the horizontal plate, respectively. The motor is used to control the rotation of the lead screw.

[0009] A fixing plate is fixedly installed at the bottom of the horizontal plate;

[0010] The detection assembly includes at least two detection assemblies on the movable plate and at least one detection assembly on the fixed plate. Each detection assembly includes a detection cylinder and a filter screen. The detection cylinder is fixedly installed longitudinally on the movable plate or the fixed plate. The detection cylinder is a hollow tubular structure. The filter screen is fixedly installed on the lower part of the inner wall of the detection cylinder.

[0011] A water-adding assembly is used to simultaneously add water to all the detection cylinders.

[0012] Furthermore, the sealing assembly also includes a sealing plug and a baffle. The sealing plug is disposed below the filter screen and maintains a seal with the inner wall of the detection cylinder. The baffle is disposed below the detection cylinder and is fixedly connected to the sealing plug.

[0013] Furthermore, the sealing assembly also includes a stop bar, which is laterally fixedly mounted on the baffle plate;

[0014] A push-down assembly is provided on the horizontal plate. The push-down assembly includes a guide rod, a mounting plate, a lifting plate, a push rod, and a cylinder. The guide rod is fixedly installed on the horizontal plate longitudinally. The mounting plate is fixedly installed on the top of the guide rod. The lifting plate is disposed on the guide rod and slidably connected to the guide rod. The push rod is fixedly installed on the lifting plate and contacts the top of the stop rod. The cylinder is used to control the up and down movement of the lifting plate.

[0015] Furthermore, the number of detection components is three, with two of the detection components disposed on the movable plate and the other detection component disposed on the fixed plate.

[0016] Furthermore, the support plate contacts the outer side of the water tank, and limit plates are respectively provided on both sides of the support plate. The limit plates are fixedly connected to the water tank and contact the support plate.

[0017] Furthermore, it also includes a water filling assembly, which includes a water tank, a water distribution pipe, a water pump, and three water outlet pipes. The water tank is fixedly installed on the horizontal plate, the water distribution pipe is fixedly installed on the top plate, the water inlet of the water pump is connected to the water tank, the water outlet of the water pump is connected to the water distribution pipe, and the three water outlet pipes correspond one-to-one with the three detection cylinders. All three water outlet pipes are connected to the water distribution pipe.

[0018] The beneficial effects of this utility model are as follows: This utility model provides a production equipment for coating white-faced kraft paper. First, pre-dried, qualified pulp is loaded into a testing cylinder on a fixed plate. Then, a lifting component loads the pulp from a water tank into a testing cylinder on a movable plate. Water is then simultaneously added to all testing cylinders via a water-adding component. By comparing the filtration speed of different testing cylinders, the pulp quality can be directly observed. Because the sampling cylinders on the movable plate collect pulp at the same height from the water tank during operation, and the sampling cylinders on the movable plate leave the pulp surface at the same time, this equipment provides more accurate detection of pulp freeness.

[0028] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0029] like Figures 1-5 As shown, this utility model provides a production equipment for coating white-faced kraft paper, including a water tank 10 and a control cabinet. The water tank 10 contains pulp, and the water tank 10 and the control cabinet are existing technologies. It also includes a support assembly 20, a lifting assembly 30, a fixing plate 70, a detection assembly 40, and a water supply assembly 60.

[0030] The support assembly 20 includes a horizontal plate 21 and two support plates 22. The horizontal plate 21 is positioned above the pool 10, and the two support plates 22 are both positioned on the ground and are fixedly connected to both ends of the horizontal plate 21.

[0031] The lifting assembly 30 includes a vertical pole 31, a top plate 32, a movable plate 33, a lead screw 34, and a motor 35. The vertical pole 31 is fixedly mounted longitudinally on the horizontal plate 21. The top plate 32 is fixedly mounted transversely on the top of the vertical pole 31. The movable plate 33 is L-shaped and is transversely mounted on the vertical pole 31, and slidably connected to it. The lead screw 34 passes longitudinally through the movable plate 33 and is threadedly connected to it; both ends of the lead screw 34 are rotatably connected to the top plate 32 and the horizontal plate 21, respectively. The motor 35 is fixedly mounted on the top plate 32 and electrically connected to the control cabinet; the motor 35 controls the rotation of the lead screw 34.

[0032] The fixing plate 70 is fixedly installed at the bottom of the horizontal plate 21.

[0033] At least two detection components 40 are provided on the movable plate 33, and at least one detection component 40 is provided on the fixed plate 70. The detection component 40 includes a detection cylinder 41 and a filter screen 42. The detection cylinder 41 is fixedly installed longitudinally on the movable plate 33 or the fixed plate 70, and the detection cylinder 41 is a hollow tubular structure. The filter screen 42 is fixedly installed on the lower part of the inner wall of the detection cylinder 41.

[0034] The water filling assembly 60 is used to simultaneously add water to all the detection cylinders 41.

[0035] In the initial state, the staff fills the test cylinder 41 on the fixed plate 70 with dried and qualified pulp, and the test cylinder 41 on the movable plate 33 and the test cylinder 41 on the fixed plate 70 are at the same height.

[0036] The specific working process of this equipment is as follows:

[0037] First, the staff controls the motor 35 to start through the control cabinet. The motor 35 drives the lead screw 34 to rotate. Under the action of the upright 31, the movable plate 33 will move down into the water tank 10 until the pulp in the water tank 10 fills the detection cylinder 41 on the movable plate 33.

[0038] Then, the staff once again controlled the motor 35 to start through the control cabinet. The motor 35 drove the lead screw 34 to reverse until the movable plate 33 was reset.

[0039] Finally, after a short while, the staff simultaneously added water to all the testing cylinders 41 through the water adding component 60. By comparing the filtration speed of different testing cylinders 41, the quality of the pulp could be visually observed, and its qualification could be determined. Because the sampling cylinders on the movable plate 33 enter the water tank 10 synchronously during operation, they will obtain the same height and amount of pulp in the water tank 10. Furthermore, the sampling cylinders on the movable plate 33 will leave the pulp surface at the same time. Therefore, this equipment is more accurate in detecting the freeness of the pulp.

[0040] In one embodiment, the detection assembly 40 further includes a sealing plug 43 and a baffle 44. The sealing plug 43 is disposed below the filter screen 42 and maintains a seal with the inner wall of the detection cylinder 41. The baffle 44 is disposed below the detection cylinder 41 and is fixedly connected to the sealing plug 43.

[0041] In the initial state, the sealing plug 43 seals the bottom of the detection cylinder 41.

[0042] After the test cylinder 41 on the movable plate 33 is filled with pulp from the water tank 10 and reset, the staff removes all the baffles 44 and sealing plugs 43 at the same time. A moment later, water is added to all the test cylinders 41 simultaneously through the water adding component 60.

[0043] The design of the sealing plug 43 and the baffle 44 can prevent leakage from the detection cylinder 41 on the movable plate 33 during the resetting process after the pulp in the water tank 10 is filled, thereby avoiding errors in the subsequent comparison process.

[0044] In one embodiment, the detection component 40 further includes a stop bar 45, which is laterally fixedly mounted on the baffle 44.

[0045] A push-down assembly 50 is provided on the horizontal plate 21. The push-down assembly 50 includes a guide rod 51, a mounting plate 52, a lifting plate 53, a push rod 54, and a cylinder 55. The guide rod 51 is fixedly mounted on the horizontal plate 21 longitudinally. The mounting plate 52 is fixedly mounted on the top of the guide rod 51 transversely. The lifting plate 53 is transversely disposed on the guide rod 51 and slidably connected to the guide rod 51. The push rod 54 is transversely fixedly mounted on the lifting plate 53 and contacts the top of the stop rod 45. The cylinder 55 is longitudinally disposed and electrically connected to the control cabinet. The cylinder body of the cylinder 55 is fixedly connected to the mounting plate 52, and the piston rod of the cylinder 55 is fixedly connected to the lifting plate 53. The cylinder 55 is used to control the up and down movement of the lifting plate 53.

[0046] When the detection cylinder 41 on the movable plate 33 is filled with pulp in the water tank 10, the movable plate 33 resets. The operator controls the piston rod of the cylinder 55 to extend via the control cabinet. At this time, the lifting plate 53 will drive the push rod 54 to move downward. The push rod 54 will simultaneously push all the stop rods 45 downward, thus allowing all the stop plates 44 and sealing plugs 43 to be removed at the same time, further facilitating the operator's operation.

[0047] In one embodiment, the number of detection components 40 is three, with two detection components 40 disposed on the movable plate 33 and the other detection component 40 disposed on the fixed plate 70.

[0048] The movable plate 33 has two detection components 40, which can avoid the single detection and further improve the accuracy of the equipment in detecting the beating degree of pulp.

[0049] In one embodiment, the support plate 22 contacts the outer side of the water tank 10, and limit plates 11 are respectively provided on both sides of the support plate 22. The limit plates 11 are fixedly connected to the water tank 10 and contact the support plate 22.

[0050] The design of the limiting plate 11 can prevent the support plate 22 and the horizontal plate 21 from shaking, thereby improving the stability of the equipment.

[0051] In one embodiment, a water supply assembly 60 is also included, comprising a water tank 61, a water distribution pipe 62, a water pump 63, and three water outlet pipes 64. The water tank 61 is fixedly mounted on the horizontal plate 21. The water distribution pipe 62 is fixedly mounted on the top plate 32. The water pump 63 is electrically connected to the control cabinet; its inlet is connected to the water tank 61, and its outlet is connected to the water distribution pipe 62. Each of the three water outlet pipes 64 corresponds to one of the three detection cylinders 41, and all three water outlet pipes 64 are connected to the water distribution pipe 62.

[0052] When the water filling component 60 is working, the control cabinet controls the water pump 63 to start. The water pump 63 will simultaneously add water from the water tank 61 to the corresponding detection cylinder 41 through the water distribution pipe 62 and the water outlet pipe 64, which further facilitates the operation of the staff.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
