Description

Technical Field

[0001] The present invention relates to the technical field of packaging cardboard drying, and in particular to a packaging cardboard drying, shaping and conveying production line and a production method. Background Art

[0002] Packaging board is a general term for paperboard used for packaging. It includes whiteboard, yellowboard, kraftboard, and corrugated board. It is generally required to have strong folding resistance and good bendability. It is made from raw materials such as wood and rice straw, pulped using various methods, and then produced on a paperboard machine. It is primarily used to make packaging cartons, but is also used as packaging and printing materials.

[0003] The production process of packaging paperboard primarily includes raw material preparation, pulping, papermaking, and processing. After the pulp is formed and pressed, it needs to be dried to remove excess moisture from the paperboard and ensure that the paperboard meets quality requirements.

[0004] In the prior art, packaging cardboard is typically dried by conveying it via a conveyor belt into a drying chamber equipped with a heater. This chamber utilizes the heat generated by the heater to dry the cardboard. Because each surface of the cardboard receives varying degrees of heat, this uneven drying speed varies at different points on the cardboard. This can lead to surface warping and warping on some parts of the cardboard, severely impacting its quality and significantly reducing the yield rate of cardboard production.

[0005] Summary of the invention,

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a packaging cardboard drying, shaping and conveying production line and production method.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0016] Optionally, two fourth sliding blocks are symmetrically installed inside the fourth sliding groove, and a cleaning brush is installed on the top of the two fourth sliding blocks.

[0017] Optionally, a production method for drying and shaping packaging paperboard includes the above-mentioned conveying production line, and the production method further includes the following steps:

[0018] Step 1: Start the drying equipment preset in the drying box, place the packaging cardboard on the corresponding placement plates in sequence, and as the conveyor belt slowly rotates, the placement plates are driven to enter the drying box in sequence for drying. As the placement plates rotate downward to the bottom of the drying box in sequence, the dried packaging cardboard can be discharged from the corresponding placement plates in sequence;

[0019] Step 2: Place the packaging cardboard on top of the placement plate, control the two first double-headed screws to drive the two second mounting seats and the shaping rollers to move away from each other, control the cover plate to drive the two shaping rollers to be located at both ends of the packaging cardboard to be dried, control the two first double-headed screws to reverse, drive the two shaping rollers to move towards each other, push the two ends of the packaging cardboard, and correct the position of the packaging cardboard on the top of the placement plate;

[0020] Step 3: While the packaging cardboard is being slowly dried by the high temperature inside the drying box, the two first double-headed screws are controlled to rotate, driving the two shaping rollers to move away from each other. With the help of the cover plate rotating downward, the two shaping rollers are respectively located at the two ends of the packaging cardboard. The two shaping rollers are controlled to move toward each other, so that the two shaping rollers clamp the two ends of the packaging cardboard. As the cover plate rotates upward and resets, the packaging cardboard is driven to transfer from the top of the placement plate to the top of the cover plate, so that the bottom of the packaging cardboard can be quickly dried.

[0021] Step 4: Transfer and reset the packaging cardboard after the above-mentioned flipping process to the top of the placement plate, rotate the cover plate downward to drive the two shaping rollers to move above the placement plate, control the two rotating rods to drive the two shaping rollers to tightly contact the top of the packaging cardboard, and control the two groups of second sliders to move towards and away from each other inside the corresponding second slide grooves, driving the two shaping rollers to crush and shape the packaging cardboard.

[0022] The beneficial effects of the present invention are:

[0023] 1. In this invention, when the packaging cardboard enters the drying box for drying, the shaping mechanism provided can, on the one hand, drive the packaging cardboard to be turned over, so that the packaging cardboard is dried evenly and the occurrence of deformation and warping problems is reduced; on the other hand, when some packaging cardboards have problems such as shape and warping, these packaging cardboards can be rolled and shaped to reduce the deformation of the surface of the packaging cardboard after drying, which may affect its own quality.

[0024] 2. In the present invention, if the packaging cardboard needs to be trimmed at both ends after drying so that its length meets the standards for subsequent processing, the two shaping rollers complete the shaping of the surface of the packaging cardboard, the rotating plate is controlled to reset, and the two shaping rollers are controlled to be located at both ends of the packaging cardboard, and the two shaping rollers can press the two ends of the packaging cardboard respectively. The two rotating shafts are controlled to drive the corresponding cutting knives to rotate and extend. As the third slider moves inside the third slide groove, the two cutting knives are driven to automatically cut the excess parts at both ends of the packaging cardboard. There is no need to use corresponding cutting equipment to cut the two ends of the dried packaging cardboard in sequence, thereby improving the production efficiency of the packaging cardboard.

[0025] 3. In this invention, after the two cutting knives cut off the excess parts at both ends of the packaging cardboard, the two rotating rods are controlled to rotate and reset, thereby driving the two shaping rollers to rotate to a horizontal state. Then, the telescopic end of the electric telescopic rod can be controlled to extend, driving the rectangular plate and the two cleaning brushes to move downward together, so that the two cleaning brushes abut against the top of the packaging cardboard. As the electric telescopic rod rotates, the two cleaning brushes are driven to rotate together, and the two cleaning brushes are controlled to adaptively move and reset in directions away from each other, so that the two cleaning brushes can rotate and clean the top and cut parts of the packaging cardboard comprehensively.

[0026] 4. In this invention, after the surface of the packaging cardboard is cleaned, the conveyor belt drives multiple placement plates to be moved out of the drying box in sequence. At this time, the two shaping rollers can be controlled to move in opposite directions to push the cut waste out from the top ends of the placement plates, avoiding the problem of collecting the waste together with the packaging cardboard when it is subsequently taken out from the inside of the placement plates, and then having to sort it out.

[0048] The relevant driving devices, driving motors and servo motors appearing in this embodiment are all high-temperature motors or other driving mechanisms that can operate stably in a high-temperature environment, thereby achieving the rotation adjustment effect of the relevant components in this embodiment; and the length of the conveyor belt 2 and the drying box 3 in this embodiment during actual use is greater than the length shown in the drawings, so as to facilitate continuous drying of multiple packaging cardboards and ensure that the drying effect of the packaging cardboards meets the requirements.

[0049] As a technical optimization solution of the present invention, a production method for drying and shaping packaging paperboard includes the above-mentioned conveying production line, and the production method further includes the following steps:

[0050] Step 1: Control the drying equipment preset in the drying box 3 to start, and place the packaging cardboard in the corresponding placement plates 5 in sequence. As the conveyor belt 2 slowly rotates, the multiple placement plates 5 can be driven to enter the drying box 3 in sequence for drying. As the multiple placement plates 5 rotate downward to the bottom of the drying box 3 in sequence, the dried packaging cardboard can be discharged from the corresponding placement plates 5 in sequence.

[0051] Step 2: Place the packaging cardboard on top of the placement plate 5, control the two first double-headed screws 18 to drive the two second mounting seats 21 and the shaping roller 10 to move away from each other, control the cover plate 6 to drive the two shaping rollers 10 to be located at both ends of the packaging cardboard to be dried, control the two first double-headed screws 18 to reverse, drive the two shaping rollers 10 to move towards each other, push the two ends of the packaging cardboard, and correct the position of the packaging cardboard on the top of the placement plate 5;

[0052] Step 3: When the packaging cardboard is slowly dried by the high temperature inside the drying box 3, the two first double-headed screws 18 are controlled to rotate, driving the two shaping rollers 10 to move away from each other. With the help of the cover plate 6 rotating downward, the two shaping rollers 10 are respectively located at the two ends of the packaging cardboard. The two shaping rollers 10 are controlled to move towards each other, so that the two shaping rollers 10 clamp the two ends of the packaging cardboard. As the cover plate 6 rotates upward and resets, the packaging cardboard is driven to transfer from the top of the placement plate 5 to the top of the cover plate 6, so that the bottom of the packaging cardboard can be quickly dried.

[0053] Step 4: The packaging cardboard after the above-mentioned turning-over process is transferred and reset to the top of the placement plate 5, and the cover plate 6 rotates downward to drive the two shaping rollers 10 to move above the placement plate 5, and the two rotating rods 16 are controlled to drive the two shaping rollers 10 to tightly abut against the top of the packaging cardboard. As the two groups of second sliders 15 are controlled to move toward and away from each other inside the corresponding second slide grooves 13, the two shaping rollers 10 are driven to crush and shape the packaging cardboard.

[0054] In the present invention, when the user uses the device, he first controls the preset drying equipment inside the drying box 3 to start, so that the temperature inside the drying box 3 reaches the drying temperature specified for the packaging cardboard, and then places the packaging cardboard to be dried in turn inside the corresponding placement plates 5. As the conveyor belt 2 slowly rotates, it drives multiple placement plates 5 to enter the drying box 3 from the opening at the left end of the drying box 3 in turn for drying. After drying, the packaging cardboard placed on the top of the multiple placement plates 5 can be discharged from the opening at the right end of the drying box 3 in turn, and as the multiple placement plates 5 rotate downward to the bottom of the drying box 3 in turn, the dried packaging cardboard can be discharged from the corresponding placement plates 5 in turn.

[0055] After the packaging cardboard to be dried is placed on the top of the placement plate 5, the packaging cardboard will be skewed on the top of the placement plate 5. In order to facilitate other subsequent operations, the two first double-headed screws 18 can be controlled to rotate first, driving the two second mounting seats 21 and the shaping roller 10 to move in opposite directions to a position that matches the length of the placement plate 5. Then, the cover plate 6 is controlled to drive the rotating plate 7 and other components on its top to rotate 180 degrees in the direction close to the placement plate 5, so that the two shaping rollers 10 are respectively located at the two ends of the packaging cardboard to be dried, and are rotated downward inside the corresponding first mounting seats 9 with the help of the two rotating rods 16, thereby driving the two shaping rollers 10 to abut against the top of the placement plate 5. As the two first double-headed screws 18 are controlled to reverse , driving the two shaping rollers 10 to move in the direction of approaching each other, and pushing the two ends of the packaging cardboard so that the position of the packaging cardboard on the top of the placement plate 5 is corrected; after the positions of the two ends of the packaging cardboard are corrected, the cover plate 6 can be controlled to rotate upward and reset, and the two shaping rollers 10 can be controlled to move in the direction of approaching each other. After resetting, the rotating plate 7 is controlled to rotate 90 degrees, and then the cover plate 6 is controlled to rotate downward 180 degrees, so that the two shaping rollers 10 are now located at the other two ends of the packaging cardboard, and the first mounting seat 9 is driven to move in the direction of approaching by means of the two sets of second sliders 15, and the two shaping rollers 10 are driven to continue to move in the direction of approaching, and the other two ends of the packaging cardboard are corrected so that the packaging cardboard is located in the center of the placement plate 5, which is convenient for subsequent other processing.

[0056] When the packaging cardboards placed on the top of the multiple placement plates 5 are slowly dried by the high temperature inside the drying box 3, the bottom of the packaging cardboard is in contact with the placement plates 5, which makes the drying speed of the bottom of the packaging cardboard slower. In order to improve the drying efficiency of the packaging cardboard, after the top of the packaging cardboard is dried for a period of time, the two first double-headed screws 18 are controlled to rotate, driving the two shaping rollers 10 to move in a direction away from each other, and then the cover plate 6 is used to rotate downward 180 degrees, so that the two shaping rollers 10 are respectively located at the two ends of the packaging cardboard, and the two rotating rods 16 are used to rotate on the corresponding first mounting seat 9. The interior rotates downward, driving the two shaping rollers 10 to abut against the top of the placement plate 5. At this time, the two shaping rollers 10 are controlled to move in a direction close to each other, so that the soft pads on the outer walls of the two shaping rollers 10 can tightly abut against the two ends of the packaging cardboard, achieving the effect of clamping and fixing the two ends of the packaging cardboard. As the cover plate 6 rotates upward and resets, the packaging cardboard is driven to transfer from the top of the placement plate 5 to the top of the horizontal cover plate 6, achieving the effect of turning the packaging cardboard over and drying it, thereby facilitating the rapid drying of the bottom of the packaging cardboard and improving the drying efficiency of the packaging cardboard.

[0057] After the packaging cardboard is dried, the moisture inside it is dried and removed, so that some of the packaging cardboard surfaces will have problems such as deformation and warping. In order to make the appearance quality of the packaging cardboard meet the standards after drying, the packaging cardboard that has been turned over can be transferred and reset to the top of the placement plate 5. By controlling the two rotating rods 16 to rotate upward at a certain angle inside the corresponding first mounting seat 9, the two shaping rollers 10 are driven to move upward together to a position flush with the top of the packaging cardboard, and then the two shaping rollers 10 are controlled to move in a direction close to each other, so that the two shaping rollers 10 move together to the packaging cardboard. The two shaping rollers 10 are driven to contact the top of the packaging cardboard by controlling the rotation of the two rotating rods 16. As the two sets of second sliders 15 are controlled to move toward and away from each other in the corresponding second chutes 13, the two shaping rollers 10 are driven to crush and shape the packaging cardboard. The first slider 11 is synchronously controlled to move back and forth in the first chute 8, driving the two shaping rollers 10 to further expand the shaping range of the packaging cardboard, thereby achieving the effect of fully shaping the packaging cardboard and reducing the problem of surface deformation of the packaging cardboard after drying, which affects its own quality.

[0058] If the dried packaging cardboard needs to be trimmed at both ends so that its length meets the standards for subsequent processing, the two shaping rollers 10 have completed the shaping process on the surface of the packaging cardboard, and the rotating plate 7 needs to be controlled to reset, and the two shaping rollers 10 are controlled to be located at both ends of the packaging cardboard respectively, and the two shaping rollers 10 can press the two ends of the packaging cardboard respectively, and the spacing between the two shaping rollers 10 is adjusted as required. Then, the two rotating shafts can be controlled to drive the corresponding cutting knives 26 to rotate and extend, so that the sharp parts of the two cutting knives 26 can respectively contact the parts to be cut of the packaging cardboard. As the third slider 23 moves inside the third slide 22, the two cutting knives 26 are driven to automatically cut the excess parts at both ends of the packaging cardboard. There is no need to use corresponding cutting equipment to cut the two ends of the dried packaging cardboard in sequence, thereby improving the production efficiency of the packaging cardboard.

[0059] After the two cutting knives 26 cut off the excess parts at both ends of the packaging cardboard, the cut waste is still pressed by the two shaping rollers 10. The two shaping rollers 10 can be controlled to move in opposite directions to push the cut waste in the direction away from the packaging cardboard, and then the two rotating rods 16 are controlled to rotate and reset, thereby driving the two shaping rollers 10 to rotate to a horizontal state. Then the telescopic end of the electric telescopic rod 27 can be controlled to extend, driving the rectangular plate 12 and the two cleaning brushes 30 to move downward together, so that the two cleaning brushes 30 abut against the top of the packaging cardboard. As the electric telescopic rod 27 rotates, the rectangular plate 12 and the two cleaning brushes 30 are driven to rotate together, and while the rectangular plate 12 and the two cleaning brushes 30 rotate, the two cleaning brushes 30 are controlled to adaptively move in opposite directions and reset, so that the two cleaning brushes 30 can comprehensively rotate and clean the top and cut parts of the packaging cardboard.

[0060] After the surface of the packaging cardboard is cleaned, the conveyor belt 2 drives multiple placement plates 5 to be moved out of the drying box 3 in sequence. At this time, the two shaping rollers 10 can be controlled to move in opposite directions to push the cut waste out from the top ends of the placement plates 5, so as to avoid the problem of collecting the waste together when the packaging cardboard is taken out from the inside of the placement plates 5, and then having to sort it out.

[0061] If during the use of the production line, the conveyor belt 2 fails, resulting in the inability to drive the multiple placement plates 5 to move, then the packaging cardboard being dried inside the drying box 3 cannot be driven to move out of the drying box 3. In order to avoid the packaging cardboard being unable to be discharged from the drying box 3 for a long time, resulting in excessive drying of the packaging cardboard and affecting subsequent use, the multiple cover plates 6 inside the drying box 3 can be controlled to rotate downward 180 degrees, and the packaging cardboard can be transferred from the top of the placement plate 5 to the top of the cover plate 6 with the help of two corresponding shaping rollers 10. The two shaping rollers 10 are controlled to move away from each other and reset to release the clamping fixation on both ends of the packaging cardboard. At this time, the control The cutting knives 26 arranged on the outer wall of one side close to the two second mounting seats 21 are both rotated upward to a vertical state, so that the two cutting knives 26 are both located at one end of the packaging cardboard. As the two third sliders 23 are controlled to move inside the corresponding third slide grooves 22, the two cutting knives 26 are driven to push the packaging cardboard between the two shaping rollers 10, and push the packaging cardboard on the top of the left end cover 6 to the right end in turn until the multiple packaging cards inside the drying box 3 are transferred to the outside of the drying box 3, thereby achieving the effect of assisting the automatic removal of the multiple packaging cards inside the drying box 3, avoiding the problem of over-drying of the multiple packaging cards at this time, and greatly improving the applicability of multiple components such as the cover 6.

[0062] After the drying and shaping of the packaging cardboard is completed, Figure 3 As shown, the two rotating rods 16 can be controlled to drive the shaping roller 10 to rotate to the top of the rotating plate 7 in turn, and with the help of the rotation of the first double-headed screw 18, the shaping roller 10 is driven to move to contact the top of the two cleaning brushes 30, and the two fourth sliders 29 are controlled to move back and forth inside the fourth slide 28, and the two cleaning brushes 30 are driven to brush the outer wall of the shaping roller 10 back and forth to clean up the paper scraps attached to the outer wall of the shaping roller 10. In conjunction with the rotation of the shaping roller 10 itself, the outer wall of the shaping roller 10 is conveniently cleaned comprehensively to facilitate the subsequent use of the shaping roller 10.
