Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, in particular to a PCR modified plastic sheet overturning conveying equipment 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, 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 adopting the method of docking and flipping two platforms to flip the sheets between them, the PCR sheets can be protected while achieving the purpose of flipping, thereby replacing manual flipping of the sheets and flipping the sheets in a flat state to avoid wrinkles. This device fixes the sheets by mesh adsorption. However, the sheets are a softer plastic structure. When contacting 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 view of 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, comprising a transmission belt, the inner cavity of the transmission belt is evenly provided with accommodating components, the left and right sides of the inner wall of the transmission belt are symmetrically provided with power components, 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 rinse 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 the inner cavity of the movable slide frame is fixedly connected to a pressure-sensitive pad, the upper part of the inner cavity of the pressure-sensitive pad is evenly provided with connecting plugs, and the top of the connecting plug is fixedly connected to a waterproof display screen. Since the inner cavity of the movable slide frame is slotted, the bottom of the movable slide frame is thinner, and when subjected to squeezing, the squeezing force can be transmitted to the pressure-sensitive pad. The outer surface of the movable slide frame is slidably connected to the middle of the inner cavity of the parallel pressure plate, and the side of the movable slide frame is rollingly connected to the outer surface of the squeezing roller. The number of the bracket motors is four, the number of the power components is two, 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 side of the outer surface of the scanning shaft away from the support base is slidably connected to the outer surface of the transmission belt.

[0008] Further, the side pressure component includes a side box shell, the top of the inner cavity of the side box shell is fixedly connected with 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 with a sliding gasket, and since the sliding gasket and the slide groove at the bottom of the inner cavity of the side box shell are mutually adapted, the upper area of ​​the sliding gasket can be approximately regarded as a relatively sealed space, the side of the inner cavity of the side box shell away from the movable sliding frame is evenly fixed with a connecting through pipe, the end of the connecting through pipe away from the movable sliding frame is fixedly connected with a hollow drainage plate, the front and rear ends of the hollow drainage plate are fixedly connected with a pressure control pump, and the left and right sides of the inner cavity of the parallel pressure plate are evenly slid with vertical sliding rods. The top end of the vertical sliding rod extends to the inside 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] Further, the flipping device includes an outer disk shell and an external control ring, the inner disk is rotatably connected to the inner wall of the outer disk shell at the axis center, the inner cavity of the inner disk is fixedly connected to a traction slide, the upper and lower sides of the inner wall of the traction slide are symmetrically provided with connecting slides, the traction slide can control the connecting slides on both sides to slide through the traction parts at both ends of the interior, the connecting slide is fixedly connected to a clamping rod at one end away from the traction slide, the inner cavity of the outer disk shell is fixedly connected to a flipping motor at the axis center away from the traction slide, and 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 output shaft of the small motor is fixedly connected to an adapting roller, and the outer surface of the adapting roller is rollingly connected to the side of the inner disk, the outer surface of the small motor is fixedly connected to the outer surface of the outer disk shell, and 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 open the internal pressure components on the upper and lower sides of the containing component here, and then places the plastic sheet on the upper surface of the lowest internal pressure component. Then the flipping device merges the internal pressure components on both sides, squeezes and fixes the internal plastic sheet. During the transfer work, the transmission belt rotates clockwise under the control of the power component, and runs the containing component to the cleaning device on the right. During the cleaning work, the cleaning equipment 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 plastic sheet is cleaned on both sides 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 it through a mesh will cause mesh indentations on the outer surface of the sheet due to the mesh pressure on the adsorption surface. This may easily lead to special marks during the subsequent lamination process. The accommodating component of the device is made of two layers of 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 marks 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 device, both sides of the plastic sheet can be effectively cleaned. During the cleaning process, the upper internal pressure component will slide up 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 provided 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 pressurize the inside of the slot where each vertical slide bar is located through the hollow drainage 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 an indentation occurs.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] Example 1, please refer to Figure 1-Figure 6 The present invention provides a technical solution: a PCR modified plastic sheet turning and 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 comprises a support base 21, the top of the support base 21 is fixedly connected with a rotating motor 23, and the outer surface of the output shaft of the rotating motor 23 is fixedly connected with a scanning shaft 22;

[0028] The containing component 3 includes an internal pressure component 31, the outer surface of which is slidably connected to a side pressure component 32, and flipping devices 4 are 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 containing component 3 through the top opening opened by the internal pressure component 31 to rinse 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 component 5 is 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, a connecting plug plate 313 is evenly arranged on the upper part of the inner cavity of the pressure-sensitive pad 312, and a waterproof display screen 314 is fixedly connected to the top of the connecting plug plate 313. Since the inner cavity of the movable slide frame 311 is slotted, the bottom of the movable slide frame 311 is relatively thin, and when subjected to squeezing, the squeezing force can be transmitted to the pressure-sensitive pad 312. The outer surface of the movable slide frame 311 is slidably 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, 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 side of the outer surface of the scanning shaft 22 away from the support base 21 is slidably connected to the outer surface of the transmission belt 1.

[0031] After moving into the cleaning device, the device 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-sided flushing is completed, the movable slide frame 311 is reset through the squeezing roller 323 to re-tighten the plastic sheet, and then the flipping devices 4 on both sides twist the containing part 3 to switch 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 the 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 avoiding the problem of excessive squeezing of the plastic sheet causing the plastic sheet to break.

[0034] Example 2, please refer to Figure 1-Figure 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 with 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 with a sliding gasket 52. Since the sliding gasket 52 and the sliding groove at the bottom of the inner cavity of the side box shell 51 are adapted to each other, the upper area of ​​the sliding gasket 52 can be approximately regarded as a relatively sealed space, and a connecting through pipe 55 is evenly fixed on the side of the inner cavity of the side box shell 51 away from the movable sliding frame 311, and a hollow drainage plate 56 is fixedly connected at one end of the connecting through pipe 55 away from the movable sliding frame 311, and a pressure control pump 57 is fixedly connected to the front and rear ends of the hollow drainage plate 56, 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 pressed 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 slidably 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 wall of the outer disk shell 41 is rotatably connected to an inner turntable 42 at the axis center. The inner cavity of the inner turntable 42 is fixedly connected to a traction slide 43 at the axis center. 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 connecting slides 44 on both sides to slide through the traction parts at the internal ends. The end of the connecting slide 44 away from the traction slide 43 is fixedly connected to a clamping rod 45. A flipping motor 46 is fixedly connected to the axis center of the inner cavity of the outer disk shell 41 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 plate 54 through the connecting spring 53. When the parallel pressure plates 321 on both sides are loose, the squeezing force on the secondary pressure 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 of 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 plate 43 of the inner rotating disk 42. When flipping the parallel pressure plates 321 on both sides, the flipping motor 46 on the back can directly twist the outer disk shell 41 to exchange the positions of the parallel pressure plates 321 on the upper and lower sides. However, the flipping motor 46 can only perform low-precision flipping work on the outer disk shell 41. The containing part 3 is easy to tilt after being flushed with water. At this time, when the containing part 3 is opened, the plastic sheet may slide out along the inclined parallel pressure plates 321. Therefore, the external control ring 47 can further twist the inner rotating disk 42 on the inner side of the outer disk shell 41 through the adapter roller 49, so that the inner rotating disk 42 and the outer disk shell 41 rotate relative to each other, thereby correcting the offset angle of the containing part 3, so that the containing part 3 always remains in a horizontal state. After being flushed with water, the flipping motor 46 and the external control ring 47 can twist the containing part 3 to a vertical state, and repeatedly rotate the containing part 3, so that the containing part 3 can dry the water stains inside and reduce the residual water stains inside.

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