Technical Field

[0001] The present application relates to the field of plastic processing, and in particular to a corrugated plate processing production line. Background Art

[0002] Corrugated panels are often used in interior decoration to enhance the aesthetics of buildings.

[0003] The existing corrugated plate processing production line includes a corrugated forming machine, which is used to process a specific corrugated shape on the processed semi-molten soft plastic plate; specifically, the corrugated forming machine includes a mounting frame, and the mounting frame is provided with a plurality of groups of corrugated processing components in the horizontal direction, and the corrugated extrusion component includes a first motor fixed on the mounting frame, and a first corrugated roller rotatably connected to the mounting frame is coaxially detachably connected to the output shaft of the first motor; a second motor fixed on the mounting frame is provided directly below the first motor, and a second corrugated roller rotatably connected to the mounting frame is coaxially detachably connected to the output shaft of the second motor; the first corrugated roller and the second corrugated roller are arranged in parallel, and a gap is left between the two for the semi-molten soft plastic plate to pass through; when the semi-molten soft plastic plate passes through the gap, the first corrugated roller and the second corrugated roller in each group of corrugated processing components can press out a specific corrugated shape on the upper and lower surfaces of the semi-molten soft plastic plate.

[0004] In the process of implementing the present application, it was found that the above technology has at least the following problems: the corrugated plates are processed in batches, and the several corrugated plates processed in each batch are often required to have different wave shapes; when processing corrugated plates with different wave shapes by the existing technology, it is necessary to frequently and synchronously switch the wave rollers on the first motor and the second motor, so as to realize the processing of corrugated plates with different wave shapes in the same batch; since there are a large number of wave rollers in the corrugated setting machine, frequently switching the wave rollers on the first motor and the second motor is time-consuming and labor-intensive, which will seriously affect the production efficiency of each batch of corrugated plates. Summary of the invention

[0005] In order to improve the production efficiency of each batch of corrugated plates, the present application provides a corrugated plate processing production line.

[0006] The present application provides a corrugated plate processing production line adopting the following technical solution:

[0007] A corrugated plate processing production line includes a feeding device for processing semi-molten plastic strips, a waveform shaping device for instantly converting wave processing components is provided on one side of the feeding device, a shearing machine is provided on one side of the waveform shaping device, and the shearing machine is used to shear the corrugated strips processed by the waveform shaping device into corrugated plates.

[0008] By adopting the above technical scheme, semi-molten plastic strips are processed by the feeding equipment and transmitted to the corrugated forming device. When different wave patterns need to be processed on the semi-molten plastic strips, the wave processing components are instantly converted by the corrugated forming device. In this way, the staff does not need to frequently switch the wave rollers, which helps to improve the production efficiency of each batch of corrugated plates.

[0009] In a specific possible implementation scheme, the waveform shaping device includes a track arranged on one side of the discharge port of the feeding equipment, and a plurality of displacement components are connected to the track, each of the displacement components is connected to a mounting frame, and the mounting frame is provided with the wave processing component, and the wave processing components on different mounting frames are used to extrude different wave shapes.

[0010] By adopting the above technical solution, by using a displacement component to drive the mounting frame to move on the track, different mounting frames can be placed at the discharge port of the feeding equipment, so that the wave processing components on different mounting frames can extrude different wave shapes. In this way, frequent manual switching of wave rollers can be avoided by overall movement, thereby improving the production efficiency of each batch of wave plates.

[0011] In a specific feasible implementation scheme, the waveform shaping device includes a mounting frame arranged on one side of the discharge port of the feeding equipment, and the wave processing component is connected to the mounting frame; the wave processing component includes a displacement member installed on the mounting frame, and the displacement member is provided with a first motor, and the first motor is connected to a first rotating rod, and the first rotating rod is connected to a first wave roller and a second wave roller; the mounting frame is also provided with another wave processing component used in conjunction with the wave processing component.

[0012] By adopting the above technical scheme, a wave shape can be extruded from a semi-molten plastic strip by the first wave roller in one wave processing component and the first wave roller in another wave processing component together; when the next wave shape needs to be extruded, the second wave roller can be installed on the first rotating rod respectively during the extrusion of the previous wave shape, and after the previous wave shape is pressed, the left and right adjacent wave processing components are first separated by the displacement member, so as to make space for the first rotating rod to rotate the second wave roller, and then the next wave shape is extruded from the semi-molten plastic strip by the second wave rollers in the two corresponding wave processing components, so that it is convenient to realize the continuous operation of the waveform shaping device, thereby improving the production efficiency of each batch of wave plates.

[0013] In a specific feasible implementation scheme, the wave shaping device includes a mounting frame arranged on one side of the discharge port of the feeding equipment, and the wave processing component is connected to the mounting frame; the wave processing component includes a first motor installed on the mounting frame, and the first motor is connected to a rotating roller, and the rotating roller is detachably connected to a wave cylinder, and the wave cylinder is used to extrude a wave shape on the semi-molten plastic strip.

[0014] By adopting the above technical solution, different wave shapes can be extruded by replacing different wave cylinders on the rotating roller before extruding another wave shape; and since replacing the wave cylinder is easier and more convenient than replacing the entire wave roller, the production efficiency of each batch of wave plates can be improved.

[0015] In a specific possible implementation manner, the mounting frame is provided with a guide pressing wheel set for pressing the side edges of the semi-molten plastic strip.

[0016] By adopting the above technical solution, the guiding and pressing wheel group can not only guide the semi-molten plastic strip being pressed, but also prevent the side edges of the semi-molten plastic strip from bulging during the pressing process, thereby facilitating improving the production quality of the corrugated board.

[0017] In a specific possible implementation scheme, the feeding equipment includes a raw material mixing device, which is used to mix different types of plastic raw materials; a cooling and molding device is provided at the discharge port of the raw material mixing device, which is used to cool the molten mixed plastic produced by the raw material mixing device into plastic strips; an oven is provided at the discharge port of the cooling and molding device, which is used to soften the plastic strips into semi-molten plastic strips.

[0018] By adopting the above technical scheme, different plastic raw materials are first mixed to produce a molten mixed plastic, and then the processed mixed plastic is cooled to make it cool into a plastic strip, and finally the plastic strip is heated to make the plastic strip become a semi-molten plastic strip, so as to facilitate the subsequent wave forming process.

[0019] In a specific possible implementation scheme, the oven includes an oven body, a conveyor belt for conveying the plastic board is provided in the oven body, and a first heating tube assembly for heating the plastic strip is also provided in the oven body; the first heating tube assembly is composed of a plurality of the first heating tubes, and the first heating tubes located in the middle area of ​​the first heating tube assembly are less than the first heating tubes in its side areas.

[0020] By adopting the above technical scheme, since the heat at the edge of the heated plastic strip is easy to dissipate, while the heat in the middle is not easy to dissipate, the first heating tube in the middle of the first heating tube assembly is less than the first heating tube at its side, which can make the temperatures of various parts of the entire plastic strip basically the same when heated, so that various parts of the plastic strip are heated synchronously to become semi-molten plastic strips, thereby improving the quality of uniformly pressing out wave shapes at various locations on the semi-molten plastic strip.

[0021] In a specific possible implementation manner, the oven body is further provided with a plurality of transverse heating tubes and a plurality of longitudinal heating tubes arranged perpendicular to the transverse heating tubes.

[0022] By adopting the above technical solution, after the plastic strip is preliminarily heated by the first heating tube assembly, the plastic strip can be further heated by the transverse heating tube and the longitudinal heating tube, thereby improving the efficiency of heating the plastic strip into a semi-molten plastic strip.

[0023] In a specific possible implementation mode, a trimming device is further provided between the wave-forming device and the shearing machine, and the trimming device is used to cut off the protruding portion of the edge of the corrugated strip.

[0024] By adopting the above technical solution and cutting out the protruding portion of the edge of the corrugated strip, the quality of the processed corrugated strip is improved.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 2. It is convenient to improve the production quality of corrugated boards;

[0028] 3. It is convenient to improve the quality of uniformly pressing out the wave shape on the semi-molten plastic strip. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-10 This application is described in further detail.

[0041] The embodiment of the present application discloses a corrugated plate processing production line. Figure 1 and Figure 2The corrugated plate processing production line includes a feeding device 1 for processing semi-molten plastic plates. A corrugated shaping device 2 is provided at the discharge port of the feeding device 1 for the semi-molten plastic plates. The corrugated shaping device 2 is used to press a specific corrugated shape on the semi-molten plastic plate to form a corresponding corrugated strip plate. A trimming device 3 is provided at the outlet of the corrugated shaping device 2. The trimming device 3 is used to cut off the protruding edge of the corrugated strip plate. A corrugated traction machine 4 is provided at the outlet of the trimming device 3. The corrugated traction machine 4 is used to traction the corrugated strip plate after trimming. A shearing machine 5 is provided at the discharge port of the corrugated traction machine 4. The shearing machine 5 is used to shear the corrugated strip plate after trimming into a plurality of corrugated plates. A stacking table 6 for stacking corrugated plates is provided at the discharge port of the shearing machine 5.

[0042] Specifically, refer to Figure 2 The feeding equipment 1 includes a raw material mixing device 11. Specifically, the raw material mixing device 11 includes a first raw material feeding component 111 and a second raw material feeding component 112. A raw material mixing component 113 is provided at the discharge port of the first raw material feeding component 111 and the second raw material feeding component 112. In this embodiment, the first raw material feeding component 111 is used to convey TPU to the raw material mixing component 113, and the second raw material feeding component is used to convey PU to the raw material mixing component 113. The raw material mixing device 11 is used to mix TPU and PU to obtain a molten mixed plastic.

[0043] The discharge port of the raw material mixing device 11 is arranged downwards for discharging the molten mixed plastic; a cooling and molding device 12 is arranged directly below the discharge port of the raw material mixing device 11, the cooling and molding device 12 is arranged for receiving the molten mixed plastic and further cooling the molten mixed plastic into plastic strips, and an oven 13 is arranged at the discharge port of the cooling and molding device 12, the oven 13 is arranged for further heating the plastic strips in the discharged and cooled state into semi-molten plastic strips.

[0044] Reference Figure 4 and Figure 5 The oven 13 includes an oven body 131, in which a conveyor belt 132 for conveying plastic strips is provided, and a first heating tube assembly 133 is provided below the conveyor belt 132 and near the feed port of the oven body 131; specifically, the first heating tube assembly 133 is composed of a plurality of first heating tubes connected side by side in the oven body 131; the number of first heating tubes in the middle area of ​​the first heating tube assembly 133 along the conveying direction is less than the number of first heating tubes in the two side areas of the first heating tube assembly 133, and the gap between the coaxial first heating tubes in the middle area of ​​the first heating tube assembly 133 along the conveying direction gradually increases.

[0045] It should be noted that the temperature of the two side areas of the plastic strip board after preliminary heating by the first heating tube assembly 133 is easy to lose, while the temperature of the middle area is not easy to lose; what the oven 13 wants to achieve is to make the temperature at each position of the strip board after rising converge.

[0046] During implementation, the conveyor belt 132 conveys the plastic strip to the first heating tube assembly 133 for heating. Since there are a large number of first heating tubes in the areas on both sides of the first heating tube assembly 133, the temperature on both sides of the plastic strip rises quickly, but the temperature also loses quickly; there are a small number of first heating tubes in the middle area of ​​the first heating tubes, and there are gaps between some coaxial first heating tubes, so the temperature in the middle area of ​​the plastic strip rises slowly, but the temperature loses slowly; as the heating time increases, the first heating tube assembly 133 can make the temperature of each position of the entire plastic strip converge after rising.

[0047] Continue to refer to Figure 4 and Figure 5 Along the conveying direction of the plastic strips, one side of the first heating tube assembly 133 is also sequentially provided with a transverse heating tube assembly 134 and a longitudinal heating assembly 135 connected to the oven 13; specifically, the transverse heating tube assembly 134 includes a plurality of transverse heating tubes evenly arranged side by side, and the first heating tube and the transverse heating tube are vertically arranged in the horizontal direction; the longitudinal heating tube assembly includes a plurality of longitudinal heating tubes evenly arranged side by side, and the longitudinal heating tube and the transverse heating tube are vertically arranged in the horizontal direction.

[0048] In practice, under the transmission of the first transmission belt, the plastic strips heated by the first heating tube assembly 133 are heated by the transverse heating tube assembly 134 and the longitudinal heating tube assembly in sequence, so as to reach a preset heating temperature.

[0049] Continue to refer to Figure 4 and Figure 5 A plurality of auxiliary heating tubes 136 are provided in the oven 13 and above the conveyor belt 132 for auxiliary heating of the plastic strips to improve the efficiency of the oven 13 in softening the plastic strips into semi-molten plastic soft strips.

[0050] Reference Figure 1 A waveform shaping device 2 is provided at the outlet of the oven 13 .

[0051] It should be noted that the waveform shaping device 2 performs waveform processing on a batch of semi-molten plastic soft strips each time, and each batch of semi-molten plastic soft strips contains several semi-molten plastic soft strips. According to actual practical needs, different semi-molten plastic soft strips need to have different waveform shapes processed. For example, different semi-molten plastic soft strips need to have different wave peak distances processed. However, each waveform shaping device 2 can only complete the processing of one waveform shape.

[0052] In one embodiment, referring to Figure 6 and Figure 7 The wave shaping device 2 includes a track 21 arranged below the outlet of the oven 13, the length direction of the track 21 is perpendicular to the conveying direction of the semi-molten plastic soft strip, and a plurality of groups of displacement components 22 are rotatably connected to the track 21, each group of displacement components 22 is connected to a mounting frame 23, and each group of displacement components 22 is used to drive the corresponding mounting frame 23 to move on the track 21; each mounting frame 23 is provided with a plurality of wave processing components 24 for processing a wave shape on the semi-molten plastic soft strip; specifically, the wave processing components 24 are sequentially arranged along the conveying direction of the semi-molten plastic soft strip; taking one of the wave processing components 24 as an example for explanation, combined with Figure 7 The wave processing assembly 24 includes a first motor 241 fixed on the mounting frame 23, and a first wave roller 242 is coaxially connected to the output shaft of the first motor 241. Figure 6 A second motor 243 is provided below the first motor 241, and a second wave roller 244 is coaxially connected to the output shaft of the second motor 243. A gap is left between the first wave roller 242 and the second wave roller 244 for the semi-molten plastic soft strip to pass through.

[0053] In implementation, the first wave roller 242 and the second wave roller 244 jointly drive the semi-molten plastic soft strip plate to move under the drive of the first motor 241 and the second motor 243. During the movement, the first wave roller 242 and the second wave roller 244 also synchronously process a wave shape on the upper and lower walls of the semi-molten plastic soft strip plate, thereby obtaining a wave strip plate.

[0054] In another embodiment, referring to Figure 8 The corrugated shaping device 2 includes a mounting frame 23 placed at the discharge port of the oven 13, and an upper and lower row of corrugated processing components 24 are arranged on the mounting frame 23 along the conveying direction of the semi-molten plastic soft strip. The corrugated processing components 24 in the upper and lower rows correspond to each other, have the same structure, and are symmetrically arranged.

[0055] Specifically, taking one row of wave processing components 24 as an example, the wave processing component 24 includes a displacement member 25 arranged along the conveying direction of the semi-molten plastic soft strip, and a first motor 241 is provided on the displacement member 25. The displacement member 25 is used to move the first motor 241 back and forth along its length direction. A first rotating rod 26 is coaxially connected to the output shaft of the first motor 241, and a first wave roller 242 placed directly above it is rotatably connected to the first rotating rod 26. The first wave roller 242 is driven by a preset second motor 243, and is also rotatably connected to a second wave roller 244 placed directly below it, and the second wave roller 244 is driven by a preset second motor 243; it should be noted that the wave shapes processed on the semi-molten plastic soft strip by the first wave roller 242 and the second wave roller 244 are different; another group of wave processing components 24 corresponding to the wave processing component 24 is placed directly below the wave processing component 24, and a gap is left between the two corresponding wave processing components 24 for the semi-molten plastic soft strip to pass through.

[0056] During implementation, when it is necessary to process the wavy shape processed by the first wave roller 242 on the semi-molten plastic soft strip, the displacement member 25 is first used to drive the first motors 241 away from each other, thereby leaving space for the first motor 241 to drive the first wave roller 242 and the second wave roller 244 to rotate around the first rotating rod 26; then the first motor 241 drives the first wave roller 242 to move to the position closest to the gap, so that the two first wave rollers 242 are closest to the gap; then the first motor 241 is reset again by the displacement member 25, and finally the corresponding first wave roller 242 is driven by the second motor 243 to process the wavy shape on the semi-molten plastic soft strip.

[0057] When it is necessary to process the semi-molten plastic soft strip into a wave shape processed by the second wave roller 244, the method of processing the wave shape processed by the first wave roller 242 can be referred to, and it will not be repeated here.

[0058] In other embodiments, reference Fig. 9 The wave shaping device 2 includes a wave processing component 24 arranged along the conveying direction of the semi-molten plastic soft strip. Specifically, the wave processing component 24 includes two upper and lower rows of first motors 241 fixed on the mounting frame 23. The first motors 241 in the two rows of first motors 241 correspond to each other in the vertical direction. A rotating roller 27 is coaxially connected to the output shaft of each first motor 241. A wave cylinder 28 can be detachably clamped on each rotating roller 27. The wave cylinder 28 is used to extrude a wave shape on the semi-molten plastic strip.

[0059] During implementation, when it is necessary to process a corresponding wave shape on a semi-molten plastic strip, the corresponding wave cylinder 28 is pre-clamped on the rotating roller 27, and then the semi-molten plastic strip is passed through the gap between the upper and lower rows of wave cylinders 28, so that the corresponding wave shape is processed on the corresponding semi-molten plastic strip; when it is necessary to process the next wave shape on the semi-molten plastic strip, the original wave cylinder 28 is removed from the corresponding rotating roller 27, and then the wave cylinder 28 corresponding to the next wave shape is replaced; since the wave cylinder 28 is connected to the corresponding rotating roller 27 in a clamping manner, compared with the method of directly replacing the entire wave roller in the prior art, the use of a detachable wave cylinder 28 that can be clamped on the rotating roller 27 can shorten the replacement time, thereby achieving an improvement in the production efficiency of each batch of wave plates.

[0060] Reference Fig.10 In the above three embodiments, a guide pressing wheel group 29 for pressing the two side edges of the semi-molten plastic strip can also be set on the corresponding mounting frame 23, and each side edge corresponds to a guide pressing wheel group 29 set along it, and each guide pressing wheel group 29 is composed of a plurality of guide pressing wheel groups 29 installed on the mounting frame 23.

[0061] It should be noted that when the corrugated roller or corrugated cylinder 28 presses against the semi-molten plastic strip, the side of the semi-molten plastic strip will bulge outwards, and the bulging part is not required by the finally processed corrugated plate.

[0062] During implementation, when the wave roller or wave drum 28 presses the semi-molten plastic strip, the protrusions generated on the side of the semi-molten plastic strip enter into the gap between adjacent guide pressing wheels; however, driven by the wave roller or wave drum 28, the semi-molten plastic strip will be conveyed along a preset direction, and during the conveying process, the guide pressing wheel group 29 located on both sides of the semi-molten plastic strip will guide the semi-molten plastic strip; and during the conveying process, the protruding parts entering the gap between adjacent guide pressing wheels will also return to the semi-molten plastic strip under the squeezing action of the guide pressing wheels, thereby producing no protruding parts on the semi-molten plastic strip.

[0063] Replay Figure 1 and Figure 2 The trimming device 3 located at the discharge port of the corrugated shaping device 2 includes a side trimming device 31, a cooling bracket 32, and an end trimming device 33 in sequence; the side trimming device 31 is used to cut off the burrs and possible protrusions reserved on the side of the semi-molten plastic strip; the cooling bracket 32 ​​is used to naturally cool the corrugated strip produced from the corrugated shaping device 2; the end trimming device 33 cuts off the burrs and possible protrusions reserved on the end of the semi-molten plastic strip.

[0064] A corrugated tractor 4 is provided at the discharge port of the trimming device 3, and the corrugated tractor 4 is used to continue to pull the corrugated strips transmitted from the trimming device 3; and further transmit the corrugated strips to the shearing machine 5 located behind it, so that the single corrugated strip is cut into several corrugated plates by the shearing machine 5; finally, the corrugated plates are placed on the stacking table 6 in sequence by manual or mechanical arms.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
