Description

Technical Field

[0001] The invention relates to the technical field of dipping and drying, and in particular to a stacking system after shearing in a wide-width production line. Background Art

[0002] The impregnation and drying production line is a production line that unwinds, impregnates, dries, cuts and stacks the rolled base paper. With the development of technology and fierce market competition, impregnated paper manufacturers have also put forward higher requirements for equipment. The impregnation and drying production line dominated by high speed and wide width is increasingly favored by the market.

[0003] The width of the impregnated paper is usually 4x8 feet (paper width is 1220mm, length is 2440mm), so the width of the impregnation production line is usually 4 feet (roller length is 1500mm), and its cutting length is 2440mm. In order to greatly improve production efficiency and reduce production costs, assuming that the production line speed is the same as that of the 4-foot impregnation production line, a wide-width impregnation drying production line (roller length is 2700mm) is used, and the production efficiency will be doubled. When the user uses an 8-foot wide production line, in order to meet the 8-foot (2440) length of impregnated paper, it is necessary to use a center splitter to split the impregnated paper from the middle into two equal widths, and then cut and stack them. At this time, the width of the impregnated paper is 1220mm and the length is 2440mm.

[0004] The traditional wide-width production line does not have a stacking system after center-cutting. When the user needs to use the center-cutting function, two left and right paper stacks will be generated. The left and right paper sheets cut after center-cutting will not be automatically separated by a certain distance. In this way, when the impregnated paper is stacked separately, the user needs to manually raise the middle part of the two wooden pallets on the stacking lifting table to achieve the purpose of separate stacking. In this way, the impregnated paper will drift, get stuck, and stack unevenly during the stacking process; when the user uses a wide-width production line to produce narrow impregnated paper, a stacking table that is too wide will affect the convenience of manual packaging and operation.

[0044] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present invention and are not limited to the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the unspecified implementation conditions are usually the conditions in conventional experiments.

[0045] See also Figure 1 , is a structural schematic diagram of an embodiment of the present invention, which provides a stacking system after center shearing of a wide-width production line. The wide-width production line includes a center-dividing mechanism 1, a shearing mechanism 2, and a conveying mechanism 4 which are arranged in sequence.

[0046] Among them, the center-dividing mechanism 1 is the prior art, including the center-dividing upper knife, the center-dividing lower knife, the transmission rod, and the driving motor. The driving motor is connected to the transmission rod through a transmission belt, and the center-dividing upper knife is connected to the cylinder. The blades of the center-dividing upper knife and the center-dividing lower knife are tangent. When cutting, the cylinder lowers the center-dividing upper knife, and the driving motor drives the transmission rod to rotate through the transmission belt, and the center-dividing lower knife rotates accordingly to complete the center-dividing shearing. The shearing mechanism 2 is the prior art, including the shearing upper knife and the shearing lower knife, and the fixed-length shearing of the impregnated paper is completed by the shearing upper knife and the shearing lower knife. The conveying mechanism 4 is a belt conveyor in the prior art.

[0047] In order to facilitate the stacking after the center shearing, a lifting and stacking mechanism is provided at the discharge end of the conveying mechanism 4 , and an airflow guiding mechanism 5 is provided between the lifting and stacking mechanism and the conveying mechanism 4 .

[0048] Combination Figure 2 The lifting and stacking mechanism includes a stacking trolley 6 that rolls with a traveling track 10, and a lifting and stacking platform 7 disposed below the traveling track 10. In this example, the traveling track 10 is disposed on a factory floor 8, and the lifting and stacking platform 7 is disposed in a pit 8-1 below the floor 8.

[0049] See also Figure 4 The lifting stacking platform 7 includes a lifting platform body and a center-split ejection mechanism 7-4 arranged on the lifting platform body. The stacking trolley 6 includes a frame 6-1, a traveling assembly 6-2 arranged at the bottom of the frame 6-1, and a center-split bracket arranged above the frame 6-1. The traveling assembly 6-2 is a prior art and includes four traveling wheels, two of which are relatively arranged and connected to a driving motor, and the frame 6-1 is driven to travel by the driving motor. A through slot 6-1a is provided in the middle of the frame 6-1 for the center-split ejection mechanism 7-4 to extend out. The center-split bracket includes two upper table frames 6-3 arranged symmetrically with respect to the center line of the through slot 6-1a. The outer sides of the upper table frames 6-3 are hinged on the frame 6-1, and a gap is provided between the two upper table frames 6-3. The center-split ejection mechanism 7-4 extends into the through slot 6-1a of the frame 6-1, and arches the middle parts of the two upper table frames 6-3 to facilitate the stacking of impregnated paper on both sides.

[0050] See also Figure 3 The airflow guide mechanism 5 includes a blowing box 5-1, an air inlet interface 5-2 connected to the inside of the blowing box 5-1, and baffles 5-3 arranged on both sides of the blowing box 5-1 in the conveying direction. The upper end surface of the blowing box 5-1 is arranged downwardly from the middle to the baffle 5-3 and is provided with a plurality of air outlet holes 5-1b. The air inlet interface 5-2 is connected to the fan, and air is supplied into the blowing box 5-1 and discharged through the air outlet holes 5-1b to form an air cushion on the upper surface of the blowing box 5-1, eliminating the static electricity generated by the impregnated paper and the conveying mechanism 4, thereby guiding the impregnated paper.

[0051] In order to facilitate the guidance of the impregnated paper, the upper end surface 5-1a of the blowing box 5-1 is arranged to be inclined downward from the conveying mechanism 4 to the lifting and stacking mechanism.

[0052] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 The lifting platform body includes a lifting assembly 7-1, a main lifting platform 7-2 arranged at the upper end of the lifting assembly 7-1, and an upper lifting platform 7-3 arranged on the main lifting platform 7-2. The upper lifting platform 7-3 is hinged on the main lifting platform 7-2 at one end away from the airflow guide mechanism 5. The upper lifting platform 7-3 can be lifted and lowered on the main lifting platform 7-2 near the airflow guide mechanism 5. Specifically, a first driving component 7-5 is provided on the main lifting platform 7-2, and the upper lifting platform 7-3 is connected to the first driving component 7-5 near the airflow guide mechanism 5. The first driving component 7-5 adopts a cylinder, and the upper lifting platform 7-3 is driven by the first driving component 7-5 to move upward, so that the stacking trolley 6 above it is arranged at an angle, which is convenient for the impregnated paper to enter the stacking trolley 6 after passing through the airflow guide mechanism 5, thereby improving the stacking efficiency. Among them, the lifting assembly 7-1 can adopt the hydraulic lifting mechanism in the prior art, which will not be described in detail in the present invention.

[0053] In this example, the center ejection mechanism 7-4 includes a second driving component 7-4a installed on the upper lifting table 7-3, and a center ejection block 7-4b connected to the second driving component 7-4a. The center ejection block 7-4b moves up and down under the drive of the second driving component 7-4a, and the through groove 6-1a matches the center ejection block 7-4b. Specifically, the center ejection block 7-4b is in the shape of a long strip and extends along the conveying direction. Accordingly, the second driving component 7-4a is respectively arranged at both ends of the length direction of the center ejection block 7-4b. The second driving component 7-4a can be an oil cylinder. The second driving component 7-4a drives the center ejection block 7-4b to move upward and abut against the upper table frame 6-3, so that the middle of the two upper table frames 6-3 is arched, thereby facilitating the stacking of impregnated paper on both sides.

[0054] In order to further optimize the implementation effect of the present invention, a rotating swing arm mechanism 6-4 is provided on the outer side of the upper table frame 6-3. Figure 8The rotating swing arm mechanism 6-4 includes a third driving component 6-4a, a connecting rod 6-4b drivingly connected to the third driving component 6-4a, and a plurality of swing arms 6-4c hinged to the connecting rod 6-4b. The swing arm 6-4c is rotatably supported on the upper table frame 6-3. The connecting rod 6-4b moves along the conveying direction under the drive of the third driving component 6-4a. The third driving component 6-4a can be a cylinder, which drives the connecting rod 6-4b to move through the third driving component 6-4a to drive the plurality of swing arms 6-4c to swing, thereby increasing or decreasing the stacking width of the stacking trolley 6 (such as Fig. 9 to meet stacking requirements.

[0055] In this example, a supporting plate 6-5 is provided at the upper end of the upper lifting platform 7-3 for stacking the impregnated paper.

[0056] A flap mechanism 3 is provided between the shearing mechanism 2 and the conveying mechanism 4, and a temporary stacking platform 9 is provided below the conveying mechanism 4. When the impregnated paper on the left and right sides is full, that is, when the stack needs to be changed, the flap mechanism 3 is opened, and the impregnated paper is sent to the temporary stacking platform 9 for stacking through the guidance of the flap mechanism 3. The flap mechanism 3 is a prior art, including a flap and a cylinder driving the flap to rotate, and the flap is driven by the cylinder to rotate a certain angle so that the impregnated paper is transported to the temporary stacking platform 9.

[0057] The working principle of the present invention is:

[0058] When stacking begins, the walking assembly 6-2 of the stacking trolley 6 falls on the walking track 10 on the ground 8, and a stop block is arranged on the walking track 10 to position the stacking trolley 6. When wide impregnated paper needs to be stacked, the swing arm 6-4c on the outer side of the center bracket of the stacking trolley 6 is extended out under the drive of the third driving component 6-4a to increase the stacking width of the stacking trolley 6. A supporting plate 6-5 is placed on the center bracket, and the lifting stacking platform 7 drives the stacking trolley 6 to move upward so that the supporting plate 6-5 is slightly lower than the airflow guide mechanism 5. The upper lifting platform 7-3 is tilted at a certain angle under the drive of the first driving component 7-5 so that the left side of the supporting plate 6-5 on the stacking trolley 6 is at the same height as the right side of the blowing box 5-1 (see Figure 6 , Figure 7 ), which is convenient for the stacking of the impregnated paper. At the same time, driven by the second driving component 7-4a, the middle ejection block 7-4b lifts up the inner end of the upper table frame 6-3 on the stacking trolley 6, and the impregnated papers on both sides begin to be stacked separately. When the impregnated paper is fully stacked, the flap mechanism 3 is opened, and the impregnated paper is sent to the temporary stacking platform 9 for stacking through the guidance of the flap mechanism 3. At this time, the lifting stacking platform 7 drives the stacking trolley 6 to descend, so that the walking component 6-2 of the stacking trolley 6 falls on the walking track 10, and the stacking trolley 6 moves from the working position M to the stacking position N (such as Figure 1 As shown), a stacking cycle is completed after the full stack of impregnated paper is transferred.

[0059] When narrow width (1220 mm in width) impregnated paper needs to be stacked, the swing arm 6-4c is retracted, a single support plate 6-5 is placed on the center bracket, and the above stacking cycle is repeated.

[0060] Thus, the stacking system solves the problem of center-split stacking in the prior art, making the stacking of the impregnated paper after center-split shearing more reliable and more orderly, and greatly reducing the breakage rate of the impregnated paper during the stacking process, thereby greatly improving the automation level of the wide-width production line, comprehensively improving the reliability of the operation of the wide-width production line, and greatly improving the production efficiency; solving the problem that impregnated papers of different widths can be produced by a wide-width production line; the variable width design of the upper table of the stacking trolley solves the problem of inconvenient operation, inspection, and packaging of narrow-width (4-foot) impregnated paper produced on a wide-width production line (8-foot).
