Description

Technical Field

[0001] The invention relates to the technical field of splicing devices, in particular to a splicing device for processing PE plates. Background Art

[0002] PE sheets are sheets made of plastic. Plastic is a synthetic polymer compound that can change its shape and style freely. With the continuous development of society, the application of plastic sheets is increasing, so there are more and more plastic sheet splicing equipment. However, some plastic sheet splicing equipment may have some defects when used. Therefore, in the process of PE sheet processing and production, when the required sheet size is larger than the size of a single PE sheet, the required specific size can be achieved by splicing sheets. By splicing small pieces of PE sheets, material waste can be reduced and each piece of material can be fully utilized.

[0003] Currently, in the process of PE sheet processing, when two sheets need to be spliced, a splicing device is required to connect them. Since most of the existing PE sheets are directly connected by the splicing device, before splicing, the sheets are simply laid on the workbench without cleaning their surfaces, resulting in dust and other dirt on the surface of the PE sheets. The dirt interferes with the contact between the sheets, isolates the contact surface of the PE sheets, and causes poor bonding in the welding area, thereby reducing the overall welding strength, resulting in insufficient welding strength, resulting in loose splicing, and further reducing the working efficiency of the PE sheet processing splicing device.

[0004] Therefore, we propose a splicing device for PE sheet processing to solve the above problems. Summary of the invention

A conveyor belt 205 is rotatably sleeved between the outer surfaces of each set of limiting shafts 204, and a sponge sleeve 206 is arranged on the outer surface of each conveyor belt 205. The tops of the two fixing frames 202 are fixed with support frames 209, and one end of the two support frames 209 is fixed with a hollow column 210. The bottoms of the two hollow columns 210 are provided with a plurality of air outlet pipes 211, and the other two fixing frames 202 are fixed with a support frame 209, and a hollow column 210 is fixed with a hollow column 210. The bottoms of the two hollow columns 210 are provided with a plurality of air outlet pipes 211. The top of the fixed frame 202 is fixedly installed with a collection box 212, the top of the two collection boxes 212 is fixedly installed with a mounting plate 213, the outer surface of one side of the two mounting plates 213 is provided with an air pump 214, the output ends of the two air pumps 214 are fixedly connected with a drainage pipe 215, the input ends of the two air pumps 214 are fixedly connected with an air intake pipe 216, the bottoms of the two roller conveyors 201 are fixedly connected to the top of the bottom plate 1, and the bottoms of the four fixed frames 202 are fixedly connected to the top of the bottom plate 1, and two of them are fixedly connected to the bottom plate 1. The outer surface of the connecting plate 203 is fixedly installed with a connecting block 207, and the outer surfaces of the two connecting blocks 207 are provided with a driving motor 208. The output ends of the two driving motors 208 are respectively fixedly connected to one end of two of the limit shafts 204, and the outer surfaces of the other sides of the two mounting plates 213 are respectively fixedly connected to one end of the two hollow columns 210, and the bottom ends of the two drainage pipes 215 respectively penetrate into the interior of the two collecting boxes 212, and the bottom ends of the two air inlet pipes 216 respectively penetrate into the interior of the two hollow columns 210.

[0035] In this embodiment, during the processing of the PE sheet, when two PE sheets need to be spliced, in order to ensure the uniform and tight connection of the sheets, one of the PE sheets is first placed away from the splicing assembly 4, so that the sheet is located between the roller conveyor 201 and the sponge sleeve 206, wherein the roller conveyor 201 is composed of a plurality of rollers arranged side by side, a frame, a driving device and a supporting structure, etc. The roller is mounted on an axis and can rotate freely. The roller is driven to rotate by a motor, and the PE sheet is placed above the roller conveyor 201. The material slides along the direction of the roller conveyor 201. The friction between the roller and the material enables the material to slide smoothly along the roller on the conveying equipment, and then the roller is started. The wheel conveying device 201 and the driving motor 208 make the roller inside the roller conveying device 201 and the sponge cover 206 rotate in the same direction, so that the PE sheet moves forward under the action of friction. At the same time, the sponge cover 206 rubs and wipes the PE sheet, thereby wiping off the dirt retained on the PE sheet. At the same time, the roller conveying device 201 and the sponge cover 206 squeeze the surface of the PE sheet to make it flat and prevent wrinkles. When the sponge cover 206 in contact with the PE sheet rotates to the lower part of the hollow column 210, the air pump 214 is started to drive the air inlet pipe 216 to extract gas into the interior of the hollow column 210, so that the interior of the hollow column 210 is in a negative pressure state, wherein, as Figure 4 As shown, the air inlet pipe 216 is composed of multiple branches, and its purpose is to make the gas entering the hollow column 210 evenly dispersed. When the interior of the hollow column 210 is in a negative pressure state, the external gas is driven to enter the interior of the hollow column 210 along the multiple air outlet pipes 211 under the action of the pressure difference, so that the dirt retained on the surface of the sponge cover 206 is sucked into the interior of the hollow column 210 under the action of the pressure difference, and finally enters the interior of the collection box 212 through the drainage pipe 215 to achieve the cleaning of the sponge cover 206. By cleaning the sponge cover 206, the cleaning efficiency of the dirt on the surface of the PE sheet is further improved. Through the action of the pretreatment component 2, the PE sheet splicing device can automatically clean and flatten the sheet surface before splicing the sheets, thereby improving the work efficiency of sheet splicing, and solving the problem in the prior art that when the sheet splicing device is used to splice PE sheets, the sheet surface is not pretreated, which easily leads to poor splicing effect.

[0036] like Figure 1-Figure 8As shown, the flip assembly 3 includes a connecting frame 301, the bottom of the connecting frame 301 is fixedly connected to the top of the bottom plate 1, an auxiliary block 302 is fixed to the outer surface of one side of the connecting frame 301, and a first forward and reverse motor 303 is arranged on the top of the auxiliary block 302. The relative inner walls of the connecting frame 301 are movably embedded with connecting shafts 304, one end of one connecting shaft 304 is fixedly connected to the output shaft of the first forward and reverse motor 303, and a positioning frame 305 is fixedly installed between one ends of the two connecting shafts 304. A positioning groove 306 is provided on the outer surface of one side of the positioning frame 305, and a plurality of support rods 308 are movably embedded in the relative inner walls of the positioning frame 305, and each two of the plurality of support rods 308 form a group, and each group of support rods 30 An eccentric shaft 307 is fixedly installed between one end of each of the support rods 308, and multiple support rods 308 are divided into two groups, one end of each of the support rods 308 in one group is fixed with a first gear 309, the outer surfaces of the multiple first gears 309 are meshed and connected with second gears 311, the outer surfaces of the multiple second gears 311 are fixed with positioning shafts 310, the outer surfaces of the multiple positioning shafts 310 are connected to the internal rotation of the positioning frame 305, and the outer surface of the other side of the positioning frame 305 is provided with a second forward and reverse motor 312, the output shaft of the second forward and reverse motor 312 is fixed with a rotating rod 313, and one end of the rotating rod 313 is fixedly installed with a driving gear 314, and the outer surface of the driving gear 314 is meshed and connected with the outer surface of one of the first gears 309.

[0037] In this embodiment, in order to further improve the cleaning of the surface of the PE sheet, when the PE sheet is removed from the roller conveyor 201 away from the splicing assembly 4, it enters the interior of the positioning frame 305 along the positioning groove 306 under the rotation of the roller, and then the second forward and reverse motor 312 is started to drive the rotating rod 313 to rotate, thereby driving the driving gear 314 to rotate, so that the first gear 309 rotates, and then drives the multiple second gears 311 to rotate, thereby driving the multiple eccentric shafts 307 to rotate upward, and then the PE sheet is squeezed and fixed. When the sheet is fixed, , start the first forward and reverse motor 303, drive the two connecting shafts 304 to rotate, and then drive the positioning frame 305 to rotate, thereby driving the PE sheet to rotate 170°, so that the PE sheet tilts downward, and then start the second forward and reverse motor 312 again, drive the rotating rod 313 to rotate in the opposite direction, and then drive the multiple first gears 309 to rotate in the opposite direction, so that the multiple eccentric shafts 307 rotate to a position away from the positioning groove 306, so that the sheet slides downward under the action of its own gravity and enters the top of the roller conveyor 201 near the position of the splicing component 4, wherein, as Figure 1As shown, the roller conveyor 201 far away from the splicing component 4 is higher than the roller conveyor 201 close to the splicing component 4. The purpose is to facilitate the transportation of the PE sheet. When the PE sheet moves to the top of the roller conveyor 201 close to the splicing component 4, the drive motor 208, the air pump 214 and the first forward and reverse motor 303 matching the PE sheet are started to clean the other side of the PE sheet. By flipping the PE sheet, double-sided cleaning of the sheet is achieved, which further improves the cleanliness of the sheet surface and improves the subsequent welding strength of the PE sheet.

[0038] like Figure 1 and Figure 9-11 As shown, the splicing component 4 includes a mounting seat 401, the bottom of the mounting seat 401 is fixedly connected to the top of the base plate 1, a mounting groove 402 is provided on the top of the mounting seat 401, a stepper motor 403 is arranged on the inner bottom surface of the mounting groove 402, the output shaft of the stepper motor 403 is fixedly connected to an auxiliary shaft 404, a turntable 405 is fixed to the top of the auxiliary shaft 404, two positioning rods 406 are fixed near the center of the top of the turntable 405, a rubber strip 407 is arranged inside the turntable 405, rectangular grooves 408 are provided on the outer surfaces of the two positioning rods 406, multi-stage electric telescopic rods 409 are provided on the inner walls of the two rectangular grooves 408, a moving frame 410 is fixed to one end of the two multi-stage electric telescopic rods 409, the outer surfaces of the two moving frames 410 are respectively slidably connected to the inner walls of the two rectangular grooves 408, and a welding joint is arranged between the outer surfaces of the two moving frames 410 Gun 411, a carrier frame 412 is arranged at the top of the turntable 405 near the edges on both sides, the bottoms of the two carrier frames 412 are fixedly connected to the top of the turntable 405, the outer surfaces of the two carrier frames 412 are fixedly installed with servo motors 413 near the top by screws, the output shafts of the two servo motors 413 are fixed with screw rods 415, the inner top surfaces of the two carrier frames 412 are provided with limiting grooves 414, the two ends of the two screw rods 415 are respectively movable and penetrate to the opposite outsides of the two carrier frames 412, the insides of the two limiting grooves 414 are slidably connected with sliders 416, the insides of the two sliders 416 are respectively threadedly connected to the outer surfaces of the two screw rods 415, cylinders 417 are arranged at the bottom of the two sliders 416, pressing plates 418 are fixedly installed at the bottoms of the two cylinders 417, and protective pads 419 are arranged at the bottoms of the two pressing plates 418.

[0039] In this embodiment, after both sides of the PE sheet are cleaned and flattened, the stepper motor 403 is started to drive the auxiliary shaft 404 to rotate, thereby driving the turntable 405 to rotate. Fig. 9As shown, two rectangular grooves are provided on the top of the turntable 405, and the purpose is to limit the PE sheet. When one of the rectangular grooves rotates to a position corresponding to the output end of the roller conveyor 201, the PE sheet moves to the top of the rectangular groove under the action of the roller. When the PE sheet is moved, the stepper motor 403 is started again to rotate the other rectangular groove to a position corresponding to the roller conveyor 201, so that the other PE sheet is moved to the inside of the corresponding rectangular groove. When both sheets are moved to the rectangular groove located at the top of the turntable 405, the two cylinders 417 are started respectively to extend them, driving the two pressing plates 418 to move downward, so that the two protective pads 419 press the two sheets respectively, wherein, as shown in FIG. Fig.11 As shown, a plurality of strip-shaped protrusions are provided at the bottom of the protective pad 419, the purpose of which is to increase the friction between it and the plate. At the same time, the rubber strip 407 used for welding is placed inside the turntable 405, and then the two servo motors 413 are started to drive the two screw rods 415 to rotate respectively, thereby driving the two pressing plates 418 to move toward the directions of the two positioning rods 406 respectively, wherein the limiting groove 414 limits the slider 416, and the movement of the pressing plate 418 drives the two PE plates to move toward the center position of the turntable 405 respectively, until the outer surfaces of the two plates move to the opposite outer surfaces of the rubber strip 407 respectively, and then the two multi-stage electric telescopic rods 409 can be started, and the welding gun 411 is started at the same time, wherein the welding gun 41 The high temperature is generated by the electric heating element, and the air is heated and ejected through the nozzle of the welding gun 411. The high-temperature air will rapidly heat the rubber strip 407 and the PE sheet to reach the melting point, so that the rubber strip 407 melts at the joint, and the PE sheet and the rubber strip 407 are fully mixed, and a uniform weld is formed by spot welding. This process ensures that the PE sheet and the rubber strip 407 are in contact and fused, thereby realizing the splicing of the sheets. The two multi-stage electric telescopic rods 409 drive the welding gun 411 to move. When the welding gun 411 moves to the top of the rubber strip 407, the rubber strip 407 can be melted and the two PE sheets can be fixed. By automatically positioning and pressing the two PE sheets, manual intervention is reduced, and the working efficiency of the PE sheet splicing device is further improved.

[0040] The use method and working principle of the device: During the processing of PE sheets, when two PE sheets need to be spliced, in order to ensure that the sheets are evenly and tightly connected, one of the PE sheets is first placed away from the splicing assembly 4 so that the sheet is located between the roller conveyor 201 and the sponge sleeve 206. Then, the roller conveyor 201 and the drive motor 208 are started so that the roller inside the roller conveyor 201 and the sponge sleeve 206 rotate in the same direction, thereby moving the PE sheet forward under the action of friction, and at the same time, the sponge sleeve 206 rubs and wipes the PE sheet, thereby wiping away the dirt trapped on the PE sheet. At the same time, the surface of the PE sheet is flattened by the extrusion of the roller conveyor 201 and the sponge sleeve 206 to prevent wrinkles. When the sponge sleeve 206 in contact with the PE sheet rotates to the lower part of the hollow column 210, the air pump 214 is started to drive the air inlet pipe 216 to extract gas into the interior of the hollow column 210, so that the interior of the hollow column 210 is in a negative pressure state. When the interior of the hollow column 210 is in a negative pressure state, the external gas is driven to enter the interior of the hollow column 210 along the multiple air outlet pipes 211 under the action of the pressure difference, so that the dirt retained on the surface of the sponge sleeve 206 is sucked into the interior of the hollow column 210 under the action of the pressure difference. Afterwards, it enters the interior of the collection box 212 through the drainage tube 215 to clean the sponge sleeve 206. By cleaning the sponge sleeve 206, the cleaning efficiency of the dirt on the surface of the PE sheet is further improved, so that the PE sheet splicing device can automatically clean and flatten the surface of the sheet before splicing the sheets. When the PE sheet is moved out from the roller conveyor 201 away from the splicing component 4, it enters the interior of the positioning frame 305 along the positioning groove 306 under the rotation of the roller, and then the second forward and reverse motor 312 is started to drive the rotating rod 313 to rotate, and then drive the driving gear 314 to rotate, so that the first gear 309 rotates, and then drives the plurality of second gears 311 to rotate, so that The plurality of eccentric shafts 307 are driven to rotate upward, thereby squeezing and fixing the PE sheet. When the sheet is fixed, the first forward and reverse motor 303 is started to drive the two connecting shafts 304 to rotate, thereby driving the positioning frame 305 to rotate, thereby driving the PE sheet to rotate 170°, so that the PE sheet tilts downward, and then the second forward and reverse motor 312 is started again to drive the rotating rod 313 to rotate in the opposite direction, thereby driving the plurality of first gears 309 to rotate in the opposite direction, thereby causing the plurality of eccentric shafts 307 to rotate to a position away from the positioning groove 306, thereby causing the sheet to slide downward under the action of its own gravity and enter the top of the roller conveyor 201 near the position of the splicing component 4, wherein, as Figure 1As shown, the roller conveyor 201 far away from the splicing component 4 is higher than the roller conveyor 201 near the splicing component 4, which is for the convenience of conveying the PE sheet. When the PE sheet moves to the top of the roller conveyor 201 near the splicing component 4, the driving motor 208, the air pump 214 and the first forward and reverse motor 303 matching the PE sheet are started to clean the other side of the PE sheet. When both sides of the PE sheet are cleaned and flattened, the stepper motor 403 is started to drive the auxiliary shaft 404 to rotate, thereby driving the turntable 405 to rotate, wherein, as shown in FIG. Fig. 9 As shown, two rectangular grooves are provided on the top of the turntable 405, and the purpose is to limit the PE sheet. When one of the rectangular grooves rotates to a position corresponding to the output end of the roller conveyor 201, the PE sheet can be moved to the top of the rectangular groove under the action of the roller. When the PE sheet is moved, the stepper motor 403 is started again to rotate the other rectangular groove to a position corresponding to the roller conveyor 201, so that the other PE sheet is moved to the inside of the corresponding rectangular groove. When both sheets are moved to the rectangular groove located at the top of the turntable 405, the two cylinders 417 are started respectively to extend them, driving the two pressing plates 418 to move downward, so that the two protective pads 419 press the two sheets respectively, and at the same time, the rubber strip 407 for welding is placed on the turntable 405. , and then start the two servo motors 413, which respectively drive the two screw rods 415 to rotate, and then drive the two pressing plates 418 to move in the directions of the two positioning rods 406, wherein the limiting groove 414 limits the slider 416, and the movement of the pressing plate 418 drives the two PE plates to move toward the center position of the turntable 405, until the outer surfaces of the two plates move to the opposite outer surfaces of the rubber strip 407, and then the two multi-stage electric telescopic rods 409 can be started, and the welding gun 411 is started at the same time to form a uniform weld by spot welding. This process ensures that the PE plate and the rubber strip 407 are in contact and fusion, thereby realizing the splicing of the plates, and the two multi-stage electric telescopic rods 409 drive the welding gun 411 to move, and when the welding gun 411 moves to the top of the rubber strip 407, the rubber strip 407 can be melted to fix the two PE plates.
