Abstract
Description
Technical Field
[0001] The invention relates to the technical field of plastic sheet production, in particular to a production method of a plastic sheet with a fastener. Background Art
[0002] Suge pad is a polymer flexible material, mainly used for pipeline repair and urban waterlogging control. It combines the flexibility, ductility and corrosion resistance of thermoplastics with the high strength and rigidity of concrete, which can effectively prevent the deterioration of concrete structures, extend the service life of buildings, and prevent leakage and penetration. Suge pad has significant tensile and tear resistance, can adapt to the deformation of the pipeline, and ensure that the repair structure layer can still function normally under deformation.
[0003] When installing the speed grid pad, it needs to be fixed to the wall or other structures by bolts, but the bolts cannot be driven directly into the speed grid pad. Therefore, it is necessary to drill a hole in the speed grid pad, and then weld a fastener at the hole, usually a hot melt sheet, on which there is a through hole for the bolt to pass through. Finally, the speed grid pad is connected to other structures by bolts passing through the hot melt sheet, thereby realizing the installation of the speed grid pad. In the prior art, when the staff drills holes in the speed grid pad or a similar plastic sheet with a special-shaped anchoring structure, the staff needs to hold a hole expander to drill holes in the speed grid pad, and then hold a hot melt gun to weld. The efficiency of drilling and welding is low, and the quality is difficult to guarantee. Summary of the invention
[0004] In order to improve the efficiency and quality of punching holes in a plastic sheet and welding fasteners, the present application provides a method for producing a plastic sheet with fasteners.

[0018] The driving assembly drives the feed frame to feed, so that the nth part to be processed enters the welding station of the welding mechanism, and at the same time, the n+1th part to be processed is fed to the punching station of the punching mechanism;
[0019] The fastener is welded to the nth position to be processed by the welding mechanism, and the n+1th position to be processed is punched by the punching mechanism.
[0020] Optionally, in step S2, when the punching mechanism is punching, the punching limit gate is in a descending state, limiting the displacement of the plastic sheet in its feeding direction.
[0021] Optionally, in step S2, after the punching mechanism completes punching, the punching limit gate remains in a descending state, the driving component drives the feed frame to feed to the welding station of the welding mechanism, and feeds the punched part to be processed to the welding station of the welding mechanism; at the same time, the next part to be processed is fed to the punching station of the punching mechanism; then, the punching limit gate is switched to a raised state, detached from the plastic sheet, the driving component drives the feed frame to retreat to the next part to be processed, and the punching limit gate is switched to a descending state.
[0022] Optionally, in step S2, when the punching mechanism punches the part to be processed, the first piston rod of the punching cylinder is first extended to punch a hole in the plastic sheet; the second piston rod of the trimming cylinder is then extended to trim the edge of the hole punched by the first piston rod.

[0026] Optionally, in step S, the hot melt gun is driven away from the hot melt sheet by a third lifting component before and after welding; when the hot melt gun is welding, it is first driven close to the hot melt sheet by the third lifting component, and then hot melt welding is performed on the hot melt sheet and the part to be processed.

[0047] Please refer to Figure 1-14 The method for producing a plastic sheet with fasteners of the present invention is based on a device for punching and welding a plastic sheet with a special-shaped anchoring structure. The device comprises: a frame 1, a feeding mechanism, a punching mechanism, a welding mechanism, a feeding mechanism and a limiting mechanism.
[0048] First of all, it should be explained that the speed pad is a type of plastic sheet 01 with a special-shaped anchoring structure 02. On one side of the speed pad in the thickness direction, there are special-shaped anchoring structures 02 densely distributed in a matrix shape. The longitudinal section of the special-shaped anchoring structure 02 is V-shaped and protrudes from the surface of the speed pad, which is used to improve the firmness of the speed pad combined with other structures. There are gaps between two rows of special-shaped anchoring structures 02 spaced apart along the width direction of the speed pad and between two rows of special-shaped anchoring structures 02 spaced apart along the length direction of the speed pad. The object of the production method of the plastic sheet 01 with fasteners of the present invention is the speed pad, and various plastic sheets 01 similar to the speed pad, with special-shaped anchoring structures 02 densely distributed in a matrix shape on the surface.
[0049] When installing, the plastic sheet 01 needs to be fixed to a structure such as a wall by bolts, but in order to avoid damage to the plastic sheet 01, the bolts cannot be driven directly into the plastic sheet 01. Therefore, it is necessary to first punch a hole in the plastic sheet 01, then weld a fastener at the hole, and finally pass the bolt through the fastener to connect with other structures, thereby achieving the installation of the plastic sheet 01. In this embodiment, the fastener is a hot melt sheet 03 as an example for explanation. The hot melt sheet 03 includes a sheet material made of plastic such as PE, which can be welded by heating and melting. Other materials that have similar functions to the hot melt sheet 03 and can be hot-melt welded with the plastic sheet 01 are all covered within the scope of the fastener described in the present invention.
[0050] A working surface is formed on the frame 1. The working surface is horizontal and is used to place the plastic sheet 01. The rolled plastic sheet 01 is unrolled onto the working surface and begins to be fed by the feeding mechanism. After each feeding distance, the punching mechanism punches holes in the plastic sheet 01. The feeding direction of the plastic sheet 01 is consistent with the length direction of the plastic sheet 01. The frame 1 includes a frame body 11 and a plurality of beams 12. The length direction of each beam 12 is parallel to the feeding direction of the plastic sheet 01. The plurality of beams 12 are evenly spaced on the frame body 11 along the width direction of the plastic sheet 01.
[0051] Please refer to Figure 1-3 The frame 11 is a rectangular parallelepiped frame for supporting the crossbeams 12. The width direction of the frame 11 is consistent with the width direction of the plastic sheet 01, and the length direction is parallel to the feeding direction of the plastic sheet 01. The crossbeams 12 are mounted on the frame 11 by welding, and the upper surfaces of each crossbeam 12 are flush, thereby forming a working surface. The number of crossbeams 12 is appropriately selected according to the width of the plastic sheet 01. In this embodiment, when punching a plastic sheet 01 with a width of 3m and a length of 50m, the number of crossbeams 12 is six.
[0052] The feeding mechanism includes a feeding frame 2, a lifting assembly and a driving assembly 3. The lifting assembly includes a punching limit gate 4 and a first lifting component 5. The punching limit gate 4 and the first lifting component 5 are arranged on the feeding frame 2 and are both located above the plastic sheet 01. The punching limit gate 4 has a descending state and a rising state. When in the descending state, the punching limit gate 4 extends into the space between two adjacent rows of special-shaped anchoring structures 02 on the plastic sheet 01 along the feeding direction of the plastic sheet 01, limiting the feeding of the plastic sheet 01. When in the rising state, the punching limit gate 4 withdraws from the space between two adjacent rows of special-shaped anchoring structures 02 on the plastic sheet 01 along the feeding direction of the plastic sheet 01, and no longer limits the feeding of the plastic sheet 01. The first lifting component 5 is used to drive the punching limit gate 4 to rise and fall, so that the punching limit gate 4 switches between the descending state and the rising state. The feeding frame 2 is slidably arranged on the frame 1. The driving assembly 3 is arranged on the frame 1, and is used to drive the feeding frame 2 to slide back and forth along the feeding direction of the plastic sheet 01, and drive the plastic sheet 01 to be fed when the first lifting component 5 is in a descending state.
[0053] The working principle of the feeding mechanism is as follows: when the plastic sheet 01 is being punched, the punching limit gate 4 is in a descending state, limiting the movement of the plastic sheet 01 in its feeding direction, which helps to ensure the quality of the punching. When the plastic sheet 01 has completed punching at the current position, the punching limit gate 4 is still in a descending state, and the driving component 3 drives the feeding frame 2 to feed a certain distance. When it reaches the next position to be punched, the punching limit gate 4 switches to a raised state and detaches from the plastic sheet 01. The driving component 3 drives the feeding frame 2 to retreat to the next position to be punched, and then the punching limit gate 4 switches to a descending state, and the punching mechanism performs the next punching.
[0054] The feeding frame 2 includes a slider 21, a punching mounting rod 22 and a connecting rod 23. A guide component 14 is provided on each side of the frame 1 along the width direction of the plastic sheet 01. The guide component 14 is used to guide the connecting rod 23 to move along the feeding direction of the plastic sheet 01. There are two sliders 21. Both ends of the punching mounting rod 22 and the connecting rod 23 are respectively connected to the two sliders 21, and the connecting rod 23 is located below the punching mounting rod 22. Both ends of the connecting rod 23 are respectively connected to the two guide components 14. The lifting mechanism and the punching mechanism are both arranged on the punching mounting rod 22. The driving assembly 3 is in transmission connection with the connecting rod 23, and can move back and forth along the feeding direction of the plastic sheet 01 under the drive of the driving assembly 3.
[0055] The connecting rod 23 includes a crossbar 231 and a longitudinal rod 232. The length direction of the crossbar 231 is consistent with the width direction of the plastic sheet 01. The length direction of the longitudinal rod 232 is parallel to the feeding direction of the plastic sheet 01. On the frame 11 of the frame 1, located below the crossbeam 12, a plurality of guide rods 15 are arranged along the width direction of the plastic sheet 01. The length direction of the guide rod 15 is parallel to the feeding direction of the plastic sheet 01. Each guide rod 15 passes through the crossbar 231 to guide the crossbar 231 to slide along the feeding direction of the plastic sheet 01. One longitudinal rod 232 is connected to each end of the crossbar 231. Two sliders 21 are respectively mounted on the upper sides of the two crossbars 231. A guide hole 141 is opened on the guide component 14 along the feeding direction of the plastic sheet 01, and a sliding rod 142 is arranged in the guide hole 141 along the axial direction of the guide hole 141. One end of the sliding rod 142 is connected to the longitudinal rod 232 adjacent thereto.
[0056] The driving component 3 can be an air cylinder, an oil cylinder, a stepper motor, etc. In this embodiment, the driving component 3 is an air cylinder, and is recorded as the first air cylinder. The cylinder body of the first air cylinder is arranged on the frame body 11 of the frame 1, and is located upstream of the connecting rod 23 in the feeding direction of the plastic sheet 01. The piston rod of the first air cylinder is horizontal, and the telescopic direction is parallel to the feeding direction of the plastic sheet 01. The end of the piston rod of the first air cylinder is connected to the middle part of the connecting rod 23. Through the telescopic movement of the piston rod of the first air cylinder, the connecting rod 23 can be driven to move along the feeding direction of the plastic sheet 01, thereby driving the feeding frame 2 as a whole to move along the feeding direction of the plastic sheet 01.
[0057] The number of the perforated mounting rods 22 can be one or more. When the number of the perforated mounting rods 22 is more than one, the stability of the components mounted thereon is better. Preferably, in this embodiment, the number of the perforated mounting rods 22 is two, and the two perforated mounting rods 22 are spaced apart from each other and are parallel to the width direction of the plastic sheet 01.
[0058] Please continue to refer to Figure 1-3 , two connecting blocks 221 are arranged at intervals on the punching mounting rod 22. Each connecting block 221 is slidably connected to the two punching mounting rods 22, so that the position of the connecting block 221 on the punching mounting rod 22 is adjustable, and each connecting block 221 can be limited by a pin or a bolt. A mounting plate 222 is connected between the two side surfaces of the two connecting blocks 221 located upstream and downstream in the feeding direction of the plastic sheet 01. A first lifting component 5 and a punching limiting gate 4 are installed on each mounting plate 222. On the two mounting plates 222, the first lifting component 5 and the punching limiting gate 4 are installed in the same manner.
[0059] The first lifting component 5 can be a cylinder, an oil cylinder, a motor, or other components. In this embodiment, the first lifting component 5 is a cylinder, and is recorded as a second cylinder. The cylinder body of the second cylinder is arranged on the upper side of the mounting plate 222, and the piston rod is extended and retracted in the vertical direction. The end of the second cylinder piston rod passes through the mounting plate 222 and is connected to the punching limit gate plate 4, thereby driving the punching limit gate plate 4 to rise and fall in the vertical direction.
[0060] The punching limit gate plate 4 is in the shape of a trapezoidal plate, which is arranged vertically, and its length gradually increases from top to bottom. The upper bottom of the punching limit gate plate 4 (corresponding to the shorter bottom side of the trapezoid) is fixedly connected to the end of the piston rod of the second cylinder. In addition, a plurality of weight-reducing holes 109 are provided on the punching limit gate plate 4 to reduce the weight of the punching limit gate plate 4. The punching limit gate plate 4 is arranged in a trapezoidal shape, and the length of the lower bottom is longer, which is used to extend between the special-shaped anchoring structures 02 to limit the plastic sheet 01, thereby ensuring the limiting effect. The length of the upper bottom is shorter, which is used to connect to the second cylinder, and cooperates with the weight-reducing holes 109 to reduce the weight of the punching limit gate plate 4, reduce the inertia of the punching limit gate plate 4, and make the lifting and lowering of the punching limit gate plate 4 faster and more accurate.
[0061] In other embodiments of the present invention, if one mounting plate 222 and the second cylinder and the punching limiting gate 4 thereon can well limit the plastic sheet 01, any one of the two mounting plates 222 can be retained.
[0062] Please refer to Figure 3-5 , the punching mechanism is arranged on the feed rack 2, and is used to punch holes on the plastic sheet 01 in the vertical direction. The punching mechanism can adopt various standard and non-standard punching equipment. As a preferred embodiment, in this embodiment, the punching mechanism includes a punching cylinder 6 and a trimming cylinder 7. The piston rod of the punching cylinder 6 is hollow. The punching cylinder 6 includes a first cylinder body 61 and a first piston rod 62. The first cylinder body 61 is installed on two punching mounting rods 22. The first piston rod 62 is telescopic in the vertical direction in the first cylinder body 61 and is hollow. A punching tool is arranged at the end of the first piston rod 62. The trimming cylinder 7 includes a second cylinder body 71 and a second piston rod 72. The second cylinder body 71 is arranged at the upper end of the first cylinder body 61. The second piston rod 72 penetrates into the first piston rod 62 and can extend from the end of the first piston rod 62 in the vertical direction. A trimming tool is arranged at the end of the second piston rod 72.
[0063] In order to limit the movement of the plastic sheet 01 in the width direction and improve the accuracy of the punching position of the punching mechanism and the quality of the punching, the first cylinder body 61 is provided with punching limit plates 63 on both sides of the plastic sheet 01 in the width direction. The punching limit plates 63 are arranged vertically, and the length direction or width direction is consistent with the feeding direction of the plastic sheet 01. The thickness of the punching limit plate 63 is less than the interval between two adjacent rows of special-shaped anchoring structures 02 along the width direction of the plastic sheet 01. During the process of punching and feeding the plastic sheet 01, the punching limit plate 63 is always located between the two adjacent rows of special-shaped anchoring structures 02 along the width direction of the plastic sheet 01, thereby limiting the movement of the plastic sheet 01 in the width direction.
[0064] There may be multiple punching mechanisms, which are set according to the number of holes that need to be punched in the width direction of the plastic sheet 01, and the installation method of each punching mechanism is the same.
[0065] It should be noted that when the first piston rod 62 and the second piston rod 72 are extended or retracted, they always pass between any two adjacent cross beams 12 of the frame 1 without interfering with the cross beams 12 .
[0066] When the punching mechanism is working, the piston rod of the punching cylinder 6 first moves vertically downward, and the punching tool is used to punch holes in the plastic sheet 01. After the punching is completed, the piston of the punching cylinder 6 contracts, and the piston of the trimming cylinder 7 moves vertically downward again, and the trimming tool is used to correct the edge of the hole punched by the punching tool, thereby ensuring the quality of the punching of the punching mechanism.
[0067] Furthermore, the punching device for the plastic sheet 01 with the special-shaped anchoring structure 02 of the present invention further includes a waste hopper (not shown in the figure). The waste hopper can be any suitable open container, which is arranged just below the punching mechanism and is used to collect waste generated when the punching mechanism punches holes, which is conducive to the cleanliness of the production site and the recycling of waste.
[0068] The limiting mechanism includes a rotating shaft 8 and a limiting wheel 81. The rotating shaft 8 is mounted on the frame 1 along the width direction of the plastic sheet 01. There are multiple limiting wheels 81, which correspond to the crossbeams 12 one by one. Each limiting wheel 81 is located above the corresponding crossbeam 12, and a gap is reserved between the corresponding crossbeam 12 for the plastic sheet 01 to pass through. In addition, each limiting wheel 81 is located between two rows of adjacent special-shaped anchoring structures 02 on the plastic sheet 01 along the width direction of the plastic sheet 01. The limiting wheel 81 can contact with the plastic sheet 01, and when the plastic sheet 01 is fed, the limiting wheel 81 rotates with the feeding of the plastic sheet 01. It is also possible not to contact with the plastic sheet 01, and only penetrate into the plastic sheet 01 between two rows of adjacent special-shaped anchoring structures 02 on the plastic sheet 01 along the width direction of the plastic sheet 01.
[0069] The limiting mechanism also includes a feed limiting gate plate 9 and a second lifting component 91. The feed limiting gate plate 9 and the second lifting component 91 are both arranged on the frame 1 and are located upstream or downstream of the feeding mechanism in the feeding direction of the plastic sheet 01. The second lifting component 91 is used to drive the feed limiting gate plate 9 to rise and fall, so that the feed limiting gate plate 9 extends into between two adjacent rows of special-shaped anchoring structures 02 on the plastic sheet 01 along the feeding direction of the plastic sheet 01, or withdraws from between two adjacent rows of special-shaped anchoring structures 02 on the plastic sheet 01 along the feeding direction of the plastic sheet 01.
[0070] The frame 1 also includes a gantry 13, which is fixed on the frame body 11 and is in a C-shape with an opening downward, and the width is the same as the width of the frame body 11. The second lifting component 91 can be a cylinder, and is recorded as a third cylinder. The cylinder body of the third cylinder is arranged on the upper side of the gantry 13, and the piston rod is retracted in the vertical direction, and is connected to the feed limit gate 9 after passing through the gantry 13. The shape of the feed limit gate 9 is a trapezoid similar to the shape of the punching feed limit gate 9, and the length direction is parallel to the width direction of the plastic sheet 01. The upper bottom (shorter length) of the feed limit gate 9 is connected to the feed limit gate 9, and the lower bottom can be extended into between two adjacent rows of special-shaped anchoring structures 02 along the feeding direction of the plastic sheet 01 under the drive of the third cylinder to limit the feeding of the plastic sheet 01. Moreover, the distance between the feed limit gate plate 9 and the punching mechanism is farther than that between the feed limit gate plate 9 and the punching mechanism, and the feed limit gate plate 9 only serves to limit the feeding of the plastic sheet 01 . Therefore, the feed limit gate plate 9 is shorter than the punching mechanism to save materials.
[0071] There are multiple feed limit gates 9 and second lifting components 91 in one-to-one correspondence. The corresponding feed limit gates 9 and second lifting components 91 are located upstream and / or downstream of the feeding mechanism in the feeding direction of the plastic sheet 01. By arranging multiple feed limit gates 9 and second lifting components 91 on the feeding route of the plastic sheet 01, the movement of the plastic sheet 01 in its feeding direction can be more reliably limited, thereby improving the quality of the punching mechanism and the accuracy of the punching position.
[0072] The welding mechanism includes a blanking assembly, a pressing assembly 102 and a welding component 103. The blanking assembly includes a receiving box 101. The receiving box 101 is arranged on the frame 1 and is located above the plastic sheet 01 with the special-shaped anchoring structure 02. Fig. 9 As shown, the two welded mounting rods 16 of the frame 1 both pass through the receiving box 101 , thereby achieving the installation of the receiving box 101 .
[0073] Please refer to Figure 7-9 , a blanking hole 1011 is provided on the containing box 101 in the vertical direction. The diameter of the blanking hole 1011 matches the diameter of the hot melt sheet 03, and a hot melt sheet 03 can be passed through. The lower side opening of the blanking hole 1011 faces the plastic sheet 01. It should be noted that the blanking hole 1011 and the hole for the welding mounting rod 16 to pass through the containing box 101 do not interfere with each other. The clamping assembly 102 includes a telescopic component. The telescopic component is arranged on the containing box 101, and can pass through the blanking hole 1011 in the vertical direction to press the hot melt sheet 03 onto the plastic sheet 01 with the special-shaped anchoring structure 02. The welding component 103 includes a hot melt gun. The hot melt gun is arranged on the frame 1 and is located below the plastic sheet 01, and is used to heat the hot melt sheet 03 so that the hot melt sheet 03 is welded to the plastic sheet 01.
[0074] The feeding mechanism includes a feeder 104 and a silo 105. The feeder 104 includes a shell 1041, a material pushing component and a connecting component 1045. The shell 1041 is in a rectangular shape, fixedly connected to the containing box 101 through the connecting component 1045, and a feeding channel 10411 is formed inside. The silo 105 is used to store the hot melt sheet 03, which is connected to the shell 1041 and communicated with the feeding channel 10411. A discharge port 10417 is formed on the side of the shell 1041 facing the welding mechanism, and the discharge port 10417 is the end of the feeding channel 10411. The connecting component 1045 is arranged between the shell 1041 and the containing box 101, and connects the discharge port 10417 with the blanking hole 1011. The material pushing component is used to push the hot melt sheet 03 in the feeding channel 10411 so that it enters the blanking hole 1011 from the feeding channel 10411.
[0075] Before welding, the part of the plastic sheet 01 to be welded is placed under the blanking hole 1011 of the receiving box 101, and a hot melt sheet 03 in the hopper 105 falls into the feeding channel 10411. The pushing component pushes the hot melt sheet 03 into the blanking hole 1011, and then falls to the part of the plastic sheet 01 to be welded. After the telescopic component passes through the blanking hole 1011, the hot melt sheet 03 is pressed against the plastic sheet 01. Finally, the hot melt gun heats the hot melt sheet 03 under the plastic sheet 01 to melt the hot melt sheet 03, and the welding is completed after the hot melt sheet 03 cools down.
[0076] Specifically, the shape of the hot melt sheet 03 can be circular, square or other shapes, but in actual use, the circular hot melt sheet 03 is welded most evenly and is more secure after welding. Therefore, as a preferred embodiment, the silo 105 is cylindrical, and a cylindrical storage space is formed therein. The diameter of the storage space matches the diameter of the hot melt sheet 03. The hot melt sheets 03 are allowed to be stacked in the thickness direction of the hot melt sheet 03 in the storage space. After the lower end of the silo 105 is connected to the housing 1041, the storage space is connected to the feeding channel 10411, so that the hot melt sheets 03 in the silo 105 can fall into the feeding channel 10411 due to gravity.
[0077] The number of hot melt sheets 03 stored in the silo 105 is related to the thickness of a single hot melt sheet 03 and the height of the silo 105. The higher the height of the silo 105 and the thinner the thickness of a single hot melt sheet 03, the more hot melt sheets 03 can be stored in the storage space. The number of hot melt sheets 03 stored in the silo 105 of the feeder 104 should be sufficient to meet the welding needs of at least one roll of plastic sheet 01.
[0078] like Fig.10As shown, when there is only one silo 105, a connection port is provided on the upper side of the housing 1041, which is recorded as the first connection port 10413. The silo 105 is connected to the first connection port 10413. The vertical projection of the first connection port 10413 in the housing 1041 falls in the feed channel 10411. The push assembly pushes the hot melt sheet 03 in the feed channel 10411 to push the hot melt sheet 03 out of the discharge port 10417.
[0079] like Fig.11 As shown, when there are two silos 105, two connection ports are provided on the upper side of the housing 1041, which are respectively recorded as the first connection port 10413 and the second connection port 10414. The vertical projections of the first connection port 10413 and the second connection port 10414 in the housing 1041 both fall within the material supply channel 10411, and the second connection port 10414 is located between the first connection port 10413 and the material outlet 10417. Hot melt sheets 03 fall from both the first connection port 10413 and the second connection port 10414. When the push assembly pushes the hot melt sheet 03 below the first connection port 10413, the hot melt sheet 03 below the second connection port 10414 will be pushed out of the material outlet 10417. When the hot melt sheet 03 in the material bin 105 on the first connection port 10413 is completely consumed, the material pushing component directly pushes the hot melt sheet 03 below the second connection port 10414 until the hot melt sheet 03 in the material bin 105 on the second connection port 10414 is completely consumed.
[0080] like Fig.12 As shown, when there are two silos 105, there is another situation: two connection ports are opened on the upper side of the shell 1041, which are respectively recorded as the second connection port 10414 and the third connection port 10415. The feed channel 10411 is extended to either side of the feed direction to form a bypass channel 10412. The orthographic projection of the second connection port 10414 in the shell 1041 along the vertical direction falls within the feed channel 10411. The orthographic projection of the third connection port 10415 in the shell 1041 along the vertical direction falls within the bypass channel 10412. At this time, the pushing component first pushes the hot melt sheet 03 below the second connection port 10414. After the hot melt sheet 03 in the material bin 105 on the second connection port 10414 is consumed, the pushing component first pushes the hot melt sheet 03 below the third connection port 10415 to below the second connection port 10414, and then pushes it out of the discharge port 10417 until the hot melt sheet 03 in the material bin 105 on the third connection port 10415 is consumed.
[0081] Since the length of a roll of plastic sheet 01 is usually 50m or longer, two silos 105 are difficult to meet the supply of hot melt sheet 03. Fig.13In a preferred embodiment of the present invention, the number of silos 105 is four. The feed channel 10411 expands to either side of the feed direction to form a bypass channel 10412. Four connection ports are provided on the upper side of the shell 1041, and the four connection ports are arranged in a square. The four connection ports are the first connection port 10413, the second connection port 10414, the third connection port 10415 and the fourth connection port 10416. The orthographic projections of the first connection port 10413 and the second connection port 10414 in the shell 1041 along the vertical direction are located in the feed channel 10411, and the second connection port 10414 is located between the first connection port 10413 and the discharge port 10417. The orthographic projections of the third connection port 10415 and the fourth connection port 10416 in the shell 1041 along the vertical direction are both located in the bypass channel 10412, and the third connection port 10415 is closer to the discharge port 10417. The pushing component can push the hot melt sheet 03 below the first connection port 10413 and the second connection port 10414 to the discharge port 10417 along the feeding direction, and can also push the hot melt sheet 03 below the third connection port 10415 to below the second connection port 10414 and push the hot melt sheet 03 below the fourth connection port 10416 to below the first connection port 10413 along a direction horizontally and perpendicular to the feeding direction.
[0082] In actual use, the hot melt sheet 03 in the material bin 105 on the second connection port 10414 is consumed first, and then the hot melt sheets 03 in the material bins 105 on the first connection port 10413 , the third connection port 10415 , and the fourth connection port 10416 are consumed in sequence.
[0083] The number of silos 105 may be more than four, and the working principle is similar to the case where there are four silos 105, which will not be described again here.
[0084] It should also be noted that the heights of the feed channel 10411 and the bypass channel 10412 are the same, and both are greater than the thickness of one hot melt sheet 03. If the heights of the feed channel 10411 and the bypass channel 10412 are sufficient to accommodate two or more stacked hot melt sheets 03, although feeding can be performed, it is easy for the hot melt sheet 03 to be blocked in the feed channel 10411 or the bypass channel 10412 due to the tilt of the hot melt sheet 03, affecting the efficiency of welding. Therefore, in a preferred embodiment of the present invention, the heights of the feed channel 10411 and the bypass channel 10412 are both greater than the thickness of one hot melt sheet 03, and less than the thickness of two stacked hot melt sheets 03. At this time, the feed channel 10411 and the bypass channel 10412 also have the function of limiting the hot melt sheet 03 in the height direction, ensuring the feeding efficiency of the feeder 104, and thus helping to ensure the efficiency of the welding operation.
[0085] The material pushing component can be an electric push rod, a cylinder, a hydraulic cylinder, etc. Since the electric push rod has the advantages of small size, high precision and easy installation, in this embodiment, the material pushing component adopts an electric push rod.
[0086] Please refer to Fig.13 , the number of silos 105 is four, and if Fig.13 When arranged in the manner shown. There are three electric push rods, namely the first electric push rod 1042, the second electric push rod 1043 and the third electric push rod 1044. Among them, the push rod of the first electric push rod 1042 extends into the feeding channel 10411 along the feeding direction, and is used to push the hot melt sheet 03 below the first connection port 10413, and then push the hot melt sheet 03 below the second connection port 10414 out of the discharge port 10417, or directly push the hot melt sheet 03 below the first connection port 10413 out of the discharge port 10417. The push rod of the second electric push rod 1043 extends into the bypass channel 10412 in a direction horizontally and perpendicular to the feeding direction, and is used to push the hot melt sheet 03 below the fourth connection port 10416 to below the first connection port 10413. The push rod of the third electric push rod 1044 extends into the bypass channel 10412 in a direction horizontally and perpendicular to the feeding direction, and is used to push the hot melt sheet 03 below the third connecting port 10415 to below the second connecting port 10414 .
[0087] Through the cooperation of the electric push rod and the material bin 105, the hot melt sheet 03 in the material bin 105 can be quickly input into the welding mechanism, thereby improving the efficiency of the welding operation.
[0088] Please continue to Figure 7-9 , the containing box 101 is in the shape of a rectangular parallelepiped. The blanking hole 1011 is opened in the middle of the containing box 101 along the vertical direction. The connecting component 1045 is in the shape of a rectangular parallelepiped, and a connecting channel 10451 is formed inside. One side opening of the connecting channel 10451 is connected to the discharge port 10417, and the other side opening is connected to the blanking hole 1011 at the middle position of the inner wall of the blanking hole 1011. After the hot melt sheet 03 is pushed out from the discharge port 10417, the push rod of the electric push rod continues to push the hot melt sheet 03, so that the hot melt sheet 03 enters the blanking hole 1011, and finally falls from the blanking hole 1011 to the position where the plastic sheet 01 needs to be welded under the action of gravity.
[0089] The clamping assembly 102 may be a clamping oil cylinder, the cylinder body of which is disposed on the upper side of the receiving box 101, the piston rod of which extends vertically into the blanking hole 1011, and its stroke is sufficient to clamp the hot melt sheet 03 onto the surface of the plastic sheet 01. In some other embodiments of the present invention, the clamping assembly 102 may also be a cylinder, a motor screw, or other suitable components.
[0090] Please refer to Figure 7 , Fig.14The hot melt gun adopts the form of electric heating. By connecting to a power source, its upper end can generate high temperature, thereby melting the hot melt sheet 03 and the plastic sheet 01 to achieve welding. When the hot melt sheet 03 and the plastic sheet 01 are melted to a degree sufficient for welding, the hot melt gun should stop heating to prevent the hot melt sheet 03 or the plastic sheet 01 from being damaged by excessive heating. However, after the hot melt gun is powered off, there is still residual temperature at the upper end, and heating cannot be stopped immediately. Therefore, in order to avoid excessive heating of the hot melt sheet 03 or the plastic sheet 01, the welding mechanism also includes a third lifting component 106. The third lifting component 106 includes a lifting cylinder. The cylinder body of the lifting cylinder is arranged on the frame 1, and the piston rod is retracted in the vertical direction. The end of the piston rod of the lifting cylinder is fixedly connected to the hot melt gun to drive the hot melt gun to move closer to or away from the hot melt sheet 03.
[0091] When the hot melt sheet 03 and the plastic sheet 01 are welded, the lifting cylinder drives the hot melt gun to rise, so that the upper end of the hot melt gun is close to the hot melt sheet 03 and the plastic sheet 01 for welding. After the hot melt sheet 03 and the plastic sheet 01 are melted to a sufficient degree for welding, the lifting cylinder drives the hot melt gun to descend, away from the hot melt sheet 03 and the plastic sheet 01, to avoid damage to the hot melt sheet 03 or the plastic sheet 01 due to excessive melting. In this way, the welding quality of the hot melt sheet 03 can be further improved.
[0092] Furthermore, if the plastic sheet 01 needs to be welded with multiple hot melt sheets 03 at intervals in the width direction thereof, multiple welding mechanisms are arranged at intervals on the frame 1 along the width direction of the plastic sheet 01 with the special-shaped anchoring structure 02. Multiple feeding mechanisms and welding mechanisms are arranged at intervals on the frame 1 along the width direction of the plastic sheet 01 in a one-to-one correspondence. In order to ensure the efficiency of welding, each feeding mechanism and welding mechanism operates synchronously. Figure 6 , Figure 7 The figure shows the situation when the number of the feeding mechanisms and the number of the welding mechanisms are both six.
[0093] Please refer to Figure 7-9 If the position of the plastic sheet 01 is offset during the welding process between the hot melt sheet 03 and the plastic sheet 01, the welding quality will be deteriorated or even the welding will fail. In order to reduce the position offset of the plastic sheet 01 during the welding operation, the device of the present invention also includes a limit assembly. The limit assembly includes a welding limit plate 107, a driving component 110 and a welding limit gate 108.
[0094] The welding limit plate 107 is vertically arranged and is arranged on one or both sides of the containing box 101 in the width direction of the plastic sheet 01 with the special-shaped anchoring structure 02. The length direction of the welding limit plate 107 is consistent with the length direction of the plastic sheet 01, and extends between two adjacent rows of special-shaped anchoring structures 02 of the plastic sheet 01 along its width direction to limit the displacement of the plastic sheet 01 in its width direction. However, the welding limit plate 107 does not contact the surface of the plastic sheet 01 and does not affect the displacement of the plastic sheet 01 along its length direction.
[0095] The driving component 110 is arranged on the telescopic component and connected to the welding limit gate 108, and is used to drive the welding limit gate 108 to rise and fall in the vertical direction. In this embodiment, the driving component 110 adopts a driving cylinder. When the number of the feeding mechanism is one, the driving cylinder is provided on both sides of the containing box 101 along the length direction of the plastic sheet 01. When the number of the feeding mechanism is multiple, a mounting plate 222 is installed on both sides of the two adjacent containing boxes 101 near the middle of the plastic sheet 01 along the length direction of the plastic sheet 01. The driving cylinder is installed on each of the two mounting plates 222. The piston rod of the driving cylinder rises and falls in the vertical direction.
[0096] The welding limit gate 108 is vertically arranged, and its length direction is consistent with the width direction of the plastic sheet 01. The welding limit gate 108 can extend between two adjacent rows of special-shaped anchoring structures 02 on the plastic sheet 01 along its length direction to limit the displacement of the plastic sheet 01 with the special-shaped anchoring structures 02 in its length direction.
[0097] One welding limit gate 108 is provided on each of the two driving cylinders, and the two welding limit gates 108 are installed in the same manner. Specifically, the welding limit gate 108 is a trapezoidal plate, one side of which is the upper bottom of the trapezoid and is connected to the end of the corresponding driving cylinder piston rod, and one side of which is the lower bottom of the trapezoid and extends between two rows of adjacent special-shaped anchoring structures 02 on the plastic sheet 01 along its length direction. In order to reduce the weight of the welding limit gate 108 and enable the welding limit gate 108 to move more quickly and accurately, a number of weight-reducing holes 109 can also be opened on the welding limit gate 108.
[0098] When the plastic sheet 01 is placed at a predetermined position for welding, the two driving cylinders drive the two welding limit gates 108 to fall down respectively, limiting the displacement of the plastic sheet 01 along its length direction, which helps to improve the quality of the welding operation. After the welding operation is completed, when it is necessary to change the workstation or remove the plastic sheet 01, the two driving cylinders drive the two welding limit gates 108 to rise up respectively.
[0099] Please refer to Fig.15Based on the above-mentioned device for punching and welding plastic sheets with special-shaped anchoring structures, the present invention discloses a method for producing plastic sheets with fasteners, which method comprises the following steps:
[0100] S1, placing the plastic sheet 01 on the working surface of the equipment frame 1 used for punching and welding the plastic sheet 01 with the special-shaped anchoring structure 02, with the side with the special-shaped anchoring structure 02 facing upward;
[0101] S2, driving the feeding frame 2 to feed by the driving component 3, so that the part to be processed on the plastic sheet 01 passes through the punching mechanism and the welding mechanism in sequence;
[0102] When the part to be processed reaches the punching station of the punching mechanism, the punching mechanism punches holes in the plastic sheet 01; when the part to be processed reaches the welding station of the welding mechanism, the welding mechanism welds the fasteners to the holes punched by the punching mechanism;
[0103] S3. Repeat step S2 until all the parts to be processed on the plastic sheet 01 are processed.
[0104] By using the above method, compared with the prior art, plastic sheets with fasteners can be produced efficiently and with high quality.
[0105] When the intervals between two adjacent rows of parts to be processed on a plastic sheet along the feeding direction are different, although the production efficiency and quality can be improved compared with the prior art, the punching mechanism and the welding mechanism cannot work at the same time because one row of parts to be processed is at the welding station of the welding mechanism, while the adjacent row of parts to be processed located upstream in the feeding direction is not at the punching station of the punching mechanism.
[0106] Therefore, as a preferred embodiment, in this embodiment, along the feeding direction of the plastic sheet 01, the parts to be processed are the first part to be processed, the second part to be processed, ..., the nth part to be processed in sequence; the interval between the punching station of the punching mechanism and the welding station of the welding mechanism is the same as the interval between two adjacent parts to be processed;
[0107] Step S2 specifically includes:
[0108] The driving assembly 3 drives the feeding frame 2 to feed, so that the first part to be processed enters the welding station of the welding mechanism, and at the same time, the second part to be processed is fed to the punching station of the punching mechanism.
[0109] The fastener is welded to the first part to be processed by a welding mechanism, and the second part to be processed is punched by a punching mechanism.
[0110] The driving assembly 3 drives the feeding frame 2 to feed, so that the second part to be processed enters the welding station of the welding mechanism, and at the same time, the third part to be processed is fed to the punching station of the punching mechanism.
[0111] The fastener is welded to the second part to be processed by the welding mechanism, and the third part to be processed is punched by the punching mechanism.
[0112] …
[0113] The driving assembly 3 drives the feeding frame 2 to feed, so that the nth part to be processed enters the welding station of the welding mechanism, and at the same time, the n+1th part to be processed is fed to the punching station of the punching mechanism.
[0114] The fastener is welded to the nth position to be processed by the welding mechanism, and the n+1th position to be processed is punched by the punching mechanism.
[0115] It should be noted that in step S3, n is a natural number greater than or equal to 2. After the welding of the nth part to be processed is completed, if the nth part to be processed is the last part to be processed, it means that this is the tail end of the plastic sheet 01, and there is no n+1th part to be processed subsequently, so the punching mechanism does not need to work anymore.
[0116] When the welding mechanism is welding, the hot melt sheet 03 required for welding is provided through the material bin 105. The process is as follows: when the part to be processed enters the welding station of the welding mechanism, one or more of the first electric push rod 1042, the second electric push rod 1043 and the third electric push rod 1044 push the hot melt sheet 03 in the feeding channel 10411 of the housing 1041 into the blanking hole 1011 of the receiving box 101, and the hot melt sheet 03 falls along the blanking hole 1011 to the part to be processed due to gravity. The pressing assembly 102 presses the hot melt sheet 03 on the part to be processed. Subsequently, the hot melt gun performs hot melt welding on the hot melt sheet 03 and the part to be processed.
[0117] Furthermore, in step S2, based on the number of fasteners required to weld a fastener at each to-be-processed portion of the plastic sheet 01, the number of bins 105 is one or more. The number of bins 105 being one, two, or four is fully described in the description of the above-mentioned device for punching and welding the plastic sheet 01 with the special-shaped anchoring structure 02, and can be appropriately selected when implementing step S2.
[0118] On the other hand, in order to ensure the quality of punching and welding, the plastic sheet 01 needs to be limited during the process of punching by the punching mechanism and welding by the welding mechanism.
[0119] Specifically, in step S2, when the punching mechanism is punching, the punching limit gate 4 is in a descending state, limiting the displacement of the plastic sheet 01 in its feeding direction. After the punching mechanism completes the punching, the punching limit gate 4 remains in a descending state, and the driving component 3 drives the feed frame to feed to the welding station of the welding mechanism, and feeds the punched part to be processed to the welding station of the welding mechanism. At the same time, the next part to be processed is fed to the punching station of the punching mechanism. Then, the punching limit gate 4 switches to a raised state, detaches from the plastic sheet 01, and the driving component 3 drives the feed frame to retreat to the next part to be processed, and the punching limit gate 4 switches to a descending state.
[0120] When the welding mechanism welds the fastener to the part to be processed, the welding limit gate 108 is in a descending state, limiting the displacement of the plastic sheet 01 in its feeding direction.
[0121] In addition to the punching limit gate 4 and the welding limit gate 108, the feed limit gate 9 is in a descending state during the punching mechanism and the welding mechanism, limiting the displacement of the plastic sheet 01 along its feeding direction. When the driving component 3 drives the feed frame to feed, the feed limit gate 9 is in a raised state, releasing the plastic sheet 01.
[0122] Through the cooperation of the punching limit gate 4, the welding limit gate 108 and the feed limit gate 9, the displacement of the plastic sheet 01 along the feed direction of the plastic sheet 01 during the punching and welding process can be limited, and the quality of the punching and welding operations can be well guaranteed.
[0123] In order to further improve the quality of the punching and welding operations, when the punching mechanism punches the part to be processed, the first piston rod 62 of the punching cylinder 6 is extended first to punch a hole in the plastic sheet 01. The second piston rod 72 of the trimming cylinder 7 is then extended to trim the edge of the hole punched by the first piston rod 62. In this way, the edge of the hole punched by the punching mechanism can be ensured to be neat and evenly melted, and then firmly welded with the hot melt sheet 03.
[0124] In addition, the hot melt gun is driven away from the hot melt sheet 03 by the third lifting component 106 before and after welding. When the hot melt gun is welding, it is first driven close to the hot melt sheet 03 by the third lifting component 106, and then the hot melt sheet 03 and the part to be processed are hot-melted. This avoids damage to the hot melt sheet 03 or the plastic sheet 1 due to excessive melting, and can further improve the welding quality of the hot melt sheet 03.
[0125] In summary, the method for producing a plastic sheet with fasteners of the present invention can produce the plastic sheet with fasteners efficiently and with high quality by using equipment for punching and welding plastic sheets with special-shaped anchoring structures.
[0126] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
