Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to a PCR modified plastic sheet turnover conveying device and a method thereof. Background Art

[0002] When PCR modified plastic sheets are being molded, the upper and lower surfaces of the sheets need to be rinsed and cleaned to ensure that the surface of the sheet is clean and tidy and to avoid contamination and damage by impurities. When cleaning the sheet, since the sheet is soft, it needs to be laid on a platform for single-sided cleaning, and then the sheet is turned over and the other side is cleaned. After the sheet is cleaned, it is transported to the molding machine for processing.

[0003] The existing publication number is CN118083534A, which is a PCR modified plastic sheet flipping and conveying device. By using two platforms to dock and flip the sheets between them, the PCR sheets can be protected while being flipped, thereby replacing manual flipping of the sheets and flipping the sheets in a flat state to avoid wrinkles. This device uses a mesh to adsorb the sheets to fix the sheets, but the sheets are a softer plastic structure. When they contact the adsorption surface, the mesh printing problem of the adsorption surface may cause mesh indentations on the outer surface of the sheet. Special marks are likely to appear during the subsequent lamination process, so improvement and optimization are needed. Summary of the Invention

[0004] In response to the problem of mesh printing pressure on the adsorption surface of the sheet in the prior art, the technical solution adopted by the present invention is: a PCR modified plastic sheet turning and conveying device, including a transmission belt, the inner cavity of the transmission belt is evenly provided with accommodating components, and the left and right sides of the inner wall of the transmission belt are symmetrically provided with power components, and the power components include a support base, the top of the support base is fixedly connected to a rotating motor, and the outer surface of the output shaft of the rotating motor is fixedly connected to a scanning shaft;

[0005] The containing component includes an internal pressure component, the outer surface of which is slidably connected to a side pressure component, and flipping devices are symmetrically arranged on the front and rear sides of the outer surface of the side pressure component. After the internal pressure component is separated from the side pressure component, water can enter the interior of the containing component through the top opening opened by the internal pressure component to flush the plastic sheet.

[0006] Furthermore, the side pressure component includes a parallel pressure plate, and a bracket motor is symmetrically fixed on the front and rear sides of the upper surface of the parallel pressure plate. The bracket motor adopts a waterproof shell, and the outer surface of the bracket motor output shaft is fixedly connected to the extrusion roller shaft. Side blocking components are symmetrically arranged on the left and right sides of the upper surface of the parallel pressure plate.

[0007] Furthermore, the internal pressure component includes a movable slide frame, the bottom of which is fixedly connected to a pressure-sensitive pad. Connecting plugs are evenly arranged on the upper portion of the pressure-sensitive pad's inner cavity, and the top of each connecting plug is fixedly connected to a waterproof display screen. Because the movable slide frame's inner cavity is slotted, its bottom is relatively thin, allowing it to transmit the squeezing force to the pressure-sensitive pad when squeezed. The outer surface of the movable slide frame is slidingly connected to the middle of the parallel pressure plate's inner cavity, and the side of the movable slide frame is rollingly connected to the outer surface of the squeezing roller. There are four bracket motors and two power components. The outer surface of the scanning shaft is rollingly connected to the inner wall of the transmission belt. The bottom of the support base is fixedly connected to the ground, and the outer surface of the scanning shaft, facing away from the support base, is slidingly connected to the outer surface of the transmission belt.

[0008] Furthermore, the side pressure component includes a side box shell, the top of the side box shell inner cavity is fixedly connected to a secondary pressure-sensitive plate, the lower surface of the secondary pressure-sensitive plate is evenly fixed with a connecting spring, the bottom end of the connecting spring is fixedly connected to a sliding gasket, and since the sliding gasket and the slide groove at the bottom of the side box shell inner cavity are adapted to each other, the upper area of ​​the sliding gasket can be approximately regarded as a relatively sealed space, the side of the side box shell inner cavity away from the movable slide frame is evenly fixed with a connecting through-tube, the end of the connecting through-tube away from the movable slide frame is fixedly connected to a hollow guide plate, the front and rear ends of the hollow guide plate are fixedly connected to a pressure control pump, and vertical sliding rods are evenly slid on the left and right sides of the parallel pressure plate inner cavity. The top end of the vertical sliding rod extends to the interior of the side box shell, and the top end of the vertical sliding rod and the lower surface of the sliding gasket are pressed against each other, the lower surface of the side box shell is fixedly connected to the outer surface of the parallel pressure plate, and the outer surface of the sliding gasket is slidably connected to the inner cavity of the side box shell.

[0009] Furthermore, the flipping device includes an outer disk shell and an external control ring. The inner turntable is rotatably connected to the inner wall of the outer disk shell at the axis center. The inner cavity of the inner turntable is fixedly connected to a traction slide at the axis center. Connecting slides are symmetrically provided on the upper and lower sides of the inner wall of the traction slide. The traction slide can control the sliding movement of the connecting slides on both sides through the traction components at both ends of the interior. The end of the connecting slide away from the traction slide is fixedly connected to a clamping rod. The inner cavity of the outer disk shell is fixedly connected to the axis center on the side away from the traction slide. The outer surface of the flipping motor is fixed in the inner cavity of the transmission belt. Small motors are evenly fixed on the front of the external control ring. The outer surface of the small motor output shaft is fixedly connected to an adapter roller, and the outer surface of the adapter roller is rollingly connected to the side of the inner turntable. The outer surface of the small motor is fixedly connected to the outer surface of the outer disk shell. The inner wall of the clamping rod is fixedly connected to the upper surface of the parallel pressure plate.

[0010] When placing the plastic sheet, the flipping device on the far left pulls apart the internal pressure components on the upper and lower sides of the containing component, and then places the plastic sheet on the upper surface of the lowermost internal pressure component. The flipping device then merges the internal pressure components on both sides and squeezes and fixes the internal plastic sheet. During the transfer work, the transmission belt rotates clockwise under the control of the power component to move the containing component to the cleaning device on the right. During the cleaning work, the cleaning device cleans the plastic sheet inside the internal pressure component. At this time, the bracket motor controls the extrusion roller to lift the upper internal pressure component, open the gap of the parallel pressure plate, and allow water to enter the internal pressure component to rinse the plastic sheet. After the plastic sheet is cleaned on one side, the internal pressure component is reset, and the flipping device twists the containing component to flip the containing component up and down, and then lifts the upper internal pressure component to rinse the other side of the plastic sheet. The cleaning work on both sides of the plastic sheet is completed, and the plastic sheet is transported back to the initial position to obtain the cleaned plastic sheet.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. Fixing the sheet by adsorbing the sheet through a mesh will cause the sheet to have a mesh indentation on the outer surface due to the mesh pressure problem of the adsorption surface. Special marks are likely to appear during the subsequent lamination process. The accommodating component of the device is made of two layers of upper and lower internal pressure components, and the internal pressure component on the inner side of the internal pressure component and the parallel pressure plate on the outer side can be separated from each other. Effective extrusion and fixation can be performed for sheets of different sizes, and the internal pressure component and the parallel pressure plate complement each other to form a smoother plane, thereby avoiding the problem of imprints on the sheet during extrusion.

[0013] 2. The containing component can be turned upside down by the flipping device, so that when the containing component is transported to the inside of the cleaning equipment, both sides of the plastic sheet can be effectively cleaned. During the cleaning process, the upper internal pressure component will slide upward relative to the side pressure component, thereby opening the top incision of the parallel pressure plate, allowing water to directly enter the containing component to rinse the outer surface of the plastic plate, so the actual processing time of the plastic sheet will be further shortened, thereby avoiding the problem that the relatively tightly wrapped plastic sheet is difficult to contact with the external water body.

[0014] 3. In order to ensure that the internal pressure component can effectively squeeze the plastic after sliding, a pressure-sensitive pad is set at the bottom of the inner cavity of the moving slide frame. When the lower surface of the moving slide frame contacts the plastic sheet, the reaction force of the plastic sheet on the bottom of the moving slide frame will press the pressure-sensitive pad, and then the pressure-sensitive pad is fed back to the waterproof display screen through the connecting plug board, thereby ensuring effective squeezing of the plastic sheet and avoiding the problem of excessive squeezing of the plastic sheet causing the plastic sheet to break.

[0015] 4. The pressure-control pumps on both sides can apply pressure to the inside of the slot where each vertical slide bar is located through the hollow guide plate, so that the vertical slide bar can quickly slide out from the inside of the side box shell, avoiding the problem that the vertical slide bar rebounds slowly and cannot keep up with the process of replacing the plastic sheet, resulting in the inability to limit the placement area of ​​the plastic sheet through the protruding vertical slide bar when placing the plastic sheet, and then the plastic sheet is squeezed by the vertical slide bar and indentations are caused.

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0027] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a PCR modified plastic sheet turnover conveying device, comprising a transmission belt 1, the inner cavity of the transmission belt 1 is evenly provided with accommodating components 3, the left and right sides of the inner wall of the transmission belt 1 are symmetrically provided with power components 2, the power component 2 includes a support base 21, the top end of the support base 21 is fixedly connected to a rotating motor 23, and the outer surface of the output shaft of the rotating motor 23 is fixedly connected to a scanning shaft 22;

[0028] The accommodating component 3 includes an internal pressure component 31, the outer surface of which is slidingly connected to a side pressure component 32, and a flipping device 4 is symmetrically arranged on the front and rear sides of the outer surface of the side pressure component 32. After the internal pressure component 31 is separated from the side pressure component 32, water can enter the interior of the accommodating component 3 through the top opening opened by the internal pressure component 31 to flush the plastic sheet.

[0029] The side pressure component 32 includes a parallel pressure plate 321, and a bracket motor 322 is symmetrically fixed on the front and rear sides of the upper surface of the parallel pressure plate 321. The bracket motor 322 adopts a waterproof shell, and the outer surface of the output shaft of the bracket motor 322 is fixedly connected to the extrusion roller 323. The side blocking components 5 are symmetrically arranged on the left and right sides of the upper surface of the parallel pressure plate 321.

[0030] The internal pressure component 31 includes a movable slide frame 311. A pressure-sensitive pad 312 is fixedly connected to the bottom of the inner cavity of the movable slide frame 311. Connecting plugs 313 are evenly arranged above the inner cavity of the pressure-sensitive pad 312. A waterproof display screen 314 is fixedly connected to the top of the connecting plugs 313. Because the inner cavity of the movable slide frame 311 is slotted, the bottom of the movable slide frame 311 is relatively thin. When squeezed, this can transmit the squeezing force to the pressure-sensitive pad 312. The outer surface of the movable slide frame 311 is slidingly connected to the middle of the inner cavity of the parallel pressure plate 321, and the side of the movable slide frame 311 is rollingly connected to the outer surface of the squeezing roller 323. There are four bracket motors 322 and two power components 2. The outer surface of the scanning shaft 22 is rollingly connected to the inner wall of the transmission belt 1. The bottom of the support base 21 is fixedly connected to the ground, and the outer surface of the scanning shaft 22, away from the support base 21, is slidingly connected to the outer surface of the transmission belt 1.

[0031] After moving into the cleaning equipment, the equipment sprays water on the containing part 3. At this time, the parallel pressure plate 321 moves the movable slide frame 311 upward through the squeezing roller 323 on the upper surface, opens the top opening of the parallel pressure plate 321, and allows external water to enter the containing part 3 to rinse the upper surface of the bottom plastic sheet. After the single-side flushing is completed, the movable slide frame 311 is reset through the squeezing roller 323 to re-press the plastic sheet, and then the flipping devices 4 on both sides twist the containing part 3 to swap the containing part 3 up and down, and then open the top opening of the parallel pressure plate 321 that has been transferred to the top to rinse the other side of the plastic sheet.

[0032] After the washing is completed, the plastic sheet is pressed tightly and transported back to its original position from the bottom area as the transmission belt 1 rotates, and the plastic sheet inside is taken out.

[0033] In order to ensure that the internal pressure component 31 can effectively squeeze the plastic after sliding, a pressure-sensitive pad 312 is provided at the bottom of the inner cavity of the movable slide frame 311. When the lower surface of the movable slide frame 311 contacts the plastic sheet, the reaction force of the plastic sheet on the bottom of the movable slide frame 311 will press the pressure-sensitive pad 312, and then the pressure-sensitive pad 312 is fed back to the waterproof display screen 314 through the connecting plug board 313, thereby ensuring that the plastic sheet is effectively squeezed and the problem of excessive squeezing of the plastic sheet causing the plastic sheet to break is avoided.

[0034] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: on the basis of Example 1, the side pressure component 32 includes a side box shell 51, and the top of the inner cavity of the side box shell 51 is fixedly connected to a secondary pressure-sensing plate 54, and the lower surface of the secondary pressure-sensing plate 54 is evenly fixed with a connecting spring 53, and the bottom end of the connecting spring 53 is fixedly connected to a sliding gasket 52. Since the sliding gasket 52 is adapted to the sliding groove at the bottom of the inner cavity of the side box shell 51, the upper area of ​​the sliding gasket 52 can be approximately regarded as a relatively sealed space, and a connecting through-tube 55 is evenly fixed on the side of the inner cavity of the side box shell 51 away from the movable slide frame 311, and the end of the connecting through-tube 55 away from the movable slide frame 311 is fixedly connected to a hollow drainage plate 56, and the front and rear ends of the hollow drainage plate 56 are fixedly connected to a pressure control pump 57, and vertical sliding rods 58 are evenly slid on the left and right sides of the inner cavity of the parallel pressure plate 321. The top end of the vertical slide rod 58 extends to the interior of the side box shell 51, and the top end of the vertical slide rod 58 and the lower surface of the sliding gasket 52 are squeezed against each other. The lower surface of the side box shell 51 is fixedly connected to the outer surface of the parallel pressure plate 321, and the outer surface of the sliding gasket 52 is slidingly connected to the inner cavity of the side box shell 51.

[0035] The flipping device 4 includes an outer disk shell 41 and an external control ring 47. The inner turntable 42 is rotatably connected to the axis of the inner wall of the outer disk shell 41, and the traction slide 43 is fixedly connected to the axis of the inner cavity of the inner turntable 42. Connecting slides 44 are symmetrically arranged on the upper and lower sides of the inner wall of the traction slide 43. The traction slide 43 can control the sliding movement of the connecting slides 44 on both sides through the traction parts at both ends of the interior. The end of the connecting slide 44 away from the traction slide 43 is fixedly connected to the clamping rod 45. The inner cavity of the outer disk shell 41 is fixedly connected to the axis on the side away from the traction slide 43. The outer surface of the flipping motor 46 is fixed in the inner cavity of the transmission belt 1. A small motor 48 is evenly fixed on the front of the external control ring 47, and the outer surface of the output shaft of the small motor 48 is fixedly connected to the adapter roller 49, and the outer surface of the adapter roller 49 is rollingly connected to the side of the inner turntable 42. The outer surface of the small motor 48 is fixedly connected to the outer surface of the outer disk shell 41, and the inner wall of the clamping rod 45 is fixedly connected to the upper surface of the parallel pressure plate 321.

[0036] There is a certain distance between the parallel pressure plates 321 on the upper and lower sides, and this distance is much larger than the thickness of the plastic sheet. Therefore, when the vertical slide bars 58 on the upper and lower sides are connected, the flipping device 4 will continue to control the parallel pressure plates 321 on both sides to approach each other, so that the lower surface of the parallel pressure plates 321 presses the plastic sheet. At this time, the vertical slide bar 58 will shrink inside the side box shell 51 and squeeze the secondary pressure-sensing plate 54 through the connecting spring 53. When the parallel pressure plates 321 on both sides are loose, the extrusion force on the secondary pressure-sensing plate 54 will also be reduced, thereby judging whether the plastic sheet has been effectively squeezed and clamped, and preventing the plastic sheet from loosening and sliding out from the inside of the accommodating component 3.

[0037] The pressure-control pumps 57 on both sides can apply pressure to the inside of the slot where each vertical slide bar 58 is located through the hollow guide plate 56, so that the vertical slide bar 58 can quickly slide out from the inside of the side box shell 51, thereby avoiding the problem that the vertical slide bar 58 rebounds slowly and cannot keep up with the process of replacing the plastic sheet, resulting in the inability to limit the placement area of ​​the plastic sheet by the protruding vertical slide bar 58 when placing the plastic sheet, and then the plastic sheet is squeezed by the vertical slide bar 58 and an indentation occurs.

[0038] The flipping device 4 controls the parallel pressure plates 321 on both sides to slide through the traction slide 43 of the inner turntable 42. When flipping the parallel pressure plates 321 on both sides, the flipping motor 46 on the back can directly twist the outer dish shell 41 so that the upper and lower parallel pressure plates 321 can be swapped. However, the flipping motor 46 can only flip the outer dish shell 41 with low precision. The container 3 is prone to tilt after being flushed with water. At this time, when the container 3 is opened, the plastic sheet may slide out along the tilted parallel pressure plates 321. Therefore, the external control ring 47 can further twist the inner turntable 42 on the inner side of the outer dish shell 41 through the adaptive roller 49, so that the inner turntable 42 and the outer dish shell 41 rotate relative to each other, thereby correcting the offset angle of the container 3 and making the container 3 always maintain a horizontal state. After flushing with water, the flipping motor 46 and the external control ring 47 can twist the container 3 to a vertical state and repeatedly rotate the container 3 so that the container 3 can dry out the water stains inside and reduce the residual water stains inside.

[0039] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
