Description

Technical Field

[0001] This invention relates to the technical field of plastic sheet production, and in particular to a method for producing plastic sheets with fasteners. Background Technology

[0002] Suge pads are a type of flexible polymer material primarily used for pipe repair and urban flood control. They combine the flexibility, ductility, and corrosion resistance of thermoplastics with the high strength and rigidity of concrete, effectively preventing the deterioration of concrete structures, extending the service life of buildings, and preventing leaks and seepage. Suge pads possess significant tensile and tear strength, adapting to pipe deformation and ensuring that the repaired structural layer continues to function normally even under deformation.

[0003] When installing a slug pad, it needs to be fixed to a structure such as a wall using bolts. However, bolts cannot be directly driven into the slug pad. Therefore, it is necessary to first drill holes in the slug pad, and then weld a fastener, usually a thermoplastic sheet, to the holes. The thermoplastic sheet has through holes for the bolts to pass through. Finally, the bolts are passed through the thermoplastic sheet to connect with other structures, thus achieving the installation of the slug pad. In existing technology, when workers drill holes in slug pads or similar plastic sheets with irregularly shaped anchoring structures, they need to use a hole expander to drill the holes and then use a thermoplastic torch to weld them. Both drilling and welding are inefficient, and the quality is difficult to guarantee. Summary of the Invention

[0004] To improve the efficiency and quality of drilling and welding fasteners on plastic sheets, this application provides a method for producing plastic sheets with fasteners.

[0005] The method for producing plastic sheets with fasteners provided by this invention adopts the following technical solution:

[0006] A method for producing a plastic sheet with fasteners, the method comprising the following steps:

[0007] S1. Place the plastic sheet on the working surface of the equipment frame for drilling and welding the plastic sheet with the irregular anchoring structure, with the side with the irregular anchoring structure facing upwards.

[0008] S2. The feed frame is driven by the drive assembly to feed the plastic sheet so that the parts to be processed pass through the punching mechanism and the welding mechanism in sequence.

[0009] When the part to be processed reaches the punching station of the punching mechanism, the punching mechanism punches a hole in the plastic sheet; when the part to be processed reaches the welding station of the welding mechanism, the welding mechanism welds the fastener to the hole punched by the punching mechanism.

[0010] S3. Repeat step S2 until all the parts to be processed on the plastic sheet are completed.

[0011] Optionally, along the feeding direction of the plastic sheet, the parts to be processed are sequentially the first part to be processed, the second part to be processed, ..., the nth part to be processed; the interval between the punching station of the punching mechanism and the welding station of the welding mechanism is the same as the distance between two adjacent parts to be processed.

[0012] Step S2 specifically includes:

[0013] The drive assembly drives the feed frame to feed, so that the first part to be processed enters the welding station of the welding mechanism, and at the same time feeds the second part to be processed to the drilling station of the drilling mechanism.

[0014] The fasteners are welded to the first part to be processed by the welding mechanism, and the second part to be processed is punched by the drilling mechanism.

[0015] The drive assembly drives the feed frame to feed, so that the second part to be processed enters the welding station of the welding mechanism, and at the same time feeds the third part to be processed to the drilling station of the drilling mechanism.

[0016] The fastener is welded to the second part to be processed by the welding mechanism, and a hole is punched in the third part to be processed by the drilling mechanism.

[0017] ...

[0018] The drive component 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 feeds the (n+1)th part to be processed to the punching station of the punching mechanism.

[0019] The fastener is welded to the nth part to be processed by the welding mechanism, and a hole is punched at the (n+1)th part to be processed by the drilling mechanism.

[0020] Optionally, in step S2, when the punching mechanism is punching, the punching limit gate is in a descending state, restricting the displacement of the plastic sheet in its feed direction.

[0021] Optionally, in step S2, after the punching mechanism completes punching, the punching limit gate remains in a lowered state, and the drive assembly drives the feed frame to feed to the welding station of the welding mechanism, feeding 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 switches to the raised state, detaches from the plastic sheet, the drive assembly drives the feed frame to retreat to the next part to be processed, and the punching limit gate switches to the lowered state.

[0022] Optionally, in step S2, when the drilling mechanism drills a hole in the part to be processed, the first piston rod of the drilling cylinder extends first to drill a hole in the plastic sheet; then the second piston rod of the trimming cylinder extends to trim the edge of the hole drilled by the first piston rod.

[0023] Optionally, in step S2, during the process of the welding mechanism welding the fastener to the part to be processed, the welding limit gate is in a descending state, which restricts the displacement of the plastic sheet in its feed direction.

[0024] Optionally, in step S2, the number of hoppers may be one or more, based on the number of fasteners required to weld a fastener to each of the processing locations on the plastic sheet.

[0025] Optionally, the fastener includes a hot melt sheet; in step S2, when the part to be processed enters the welding station of the welding mechanism, one or more of the first electric push rod, the second electric push rod, and the third electric push rod push the hot melt sheet in the housing feeding channel into the discharge hole of the receiving box, and the hot melt sheet falls down along the discharge hole onto the part to be processed due to gravity; the clamping assembly presses the hot melt sheet onto the part to be processed; subsequently, the hot melt gun performs hot melt welding on the hot melt sheet and the part to be processed.

[0026] Optionally, in step S, before or after welding, the hot melt gun is driven away from the hot melt sheet by the third lifting component; when welding, the hot melt gun is driven closer to the hot melt sheet by the third lifting component, and then the hot melt sheet and the part to be processed are hot melt welded.

[0027] Optionally, in step S2, during the drilling process of the drilling mechanism and the welding process of the welding mechanism, the feed limit gate is in a lowered state to restrict the displacement of the plastic sheet along its feed direction; when the drive assembly drives the feed frame to feed, the feed limit gate is in an raised state to release the plastic sheet.

[0028] As described above, the method for producing plastic sheets with fasteners according to the present invention has at least the following beneficial effects: the method for producing plastic sheets with fasteners according to the present invention can produce plastic sheets with fasteners efficiently and with high quality by using equipment for drilling and welding plastic sheets with irregular anchoring structures.

[0047] Please refer to Figure 1-14 The present invention provides a method for producing plastic sheets with fasteners based on an apparatus for drilling and welding plastic sheets with irregularly shaped anchoring structures. The apparatus includes: a frame 1, a feeding mechanism, a drilling mechanism, a welding mechanism, a material feeding mechanism, and a limiting mechanism.

[0048] First, it should be noted that the fastener pad is one type of plastic sheet 01 with irregularly shaped anchoring structures 02. One side of its thickness direction has a matrix of densely distributed irregularly shaped anchoring structures 02. The longitudinal section of each irregularly shaped anchoring structure 02 is V-shaped, protruding from the surface of the fastener pad to improve the firmness of the fastener pad's connection with other structures. There are gaps between two rows of irregularly shaped anchoring structures 02 spaced apart along the width direction of the fastener pad and between two rows of irregularly shaped anchoring structures 02 spaced apart along the length direction of the fastener pad. The production method of the plastic sheet 01 with fasteners of the present invention is applied to the fastener pad, as well as various plastic sheets 01 similar to the fastener pad, whose surfaces are densely covered with irregularly shaped anchoring structures 02 in a matrix pattern.

[0049] When installing the plastic sheet 01, it needs to be fixed to a structure such as a wall using bolts. However, to avoid damage to the plastic sheet 01, bolts cannot be directly driven into it. Therefore, holes need to be drilled in the plastic sheet 01 first, then a fastener is welded to the hole, and finally, bolts are passed through the fastener to connect it to other structures, thus achieving the installation of the plastic sheet 01. In this embodiment, a hot-melt sheet 03 is used as an example of a fastener. The hot-melt sheet 03 is a sheet material made of plastics such as PE, which can be welded by heating and melting. Other materials with similar functions to the hot-melt sheet 03 that can be hot-melted and welded to the plastic sheet 01 are all included within the scope of the fasteners described in this invention.

[0050] A working surface is formed on the frame 1. The working surface is horizontal and used to place the plastic sheet 01. The rolled plastic sheet 01 is unwound onto the working surface and fed by the feeding mechanism. Every certain distance is fed, and 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 multiple crossbeams 12. The length direction of each crossbeam 12 is parallel to the feeding direction of the plastic sheet 01. The multiple crossbeams 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 frame used to support the crossbeams 12. The width of the frame 11 is consistent with the width of the plastic sheet 01, and its length is parallel to the feed direction of the plastic sheet 01. The crossbeams 12 are welded onto the frame 11, with the upper surfaces of each crossbeam 12 flush, thus 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 drilling holes in a plastic sheet 01 with a width of 3m and a length of 50m, six crossbeams 12 are used.

[0052] The feeding mechanism includes a feeding frame 2, a lifting assembly, and a drive 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 mounted on the feeding frame 2 and are both located above the plastic sheet 01. The punching limit gate 4 has a lowered state and a raised state. In the lowered state, the punching limit gate 4 extends between two adjacent rows of irregular anchoring structures 02 along the feeding direction of the plastic sheet 01, restricting the feeding of the plastic sheet 01. In the raised state, the punching limit gate 4 retracts from between the two adjacent rows of irregular anchoring structures 02 along the feeding direction of the plastic sheet 01, no longer restricting 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 lowered state and the raised state. The feeding frame 2 is slidably mounted on the frame 1. The drive assembly 3 is mounted on the frame 1 and is used to drive the feed frame 2 to slide back and forth along the feeding direction of the plastic sheet 01. When the first lifting component 5 is in the lowering state, it drives the plastic sheet 01 to feed.

[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 lowered state, restricting the movement of the plastic sheet 01 in its feeding direction, which helps to ensure the quality of the punching. After the plastic sheet 01 is punched at the current position, the punching limit gate 4 is still in a lowered state. The drive assembly 3 drives the feed 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, disengaging from the plastic sheet 01. The drive assembly 3 drives the feed frame 2 to retreat to the next position to be punched, and then the punching limit gate 4 switches to a lowered state, and the punching mechanism performs the next punching operation.

[0054] The feed 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 guides the connecting rod 23 to move along the feed 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 connected to the two sliders 21 respectively, and the connecting rod 23 is located below the punching mounting rod 22. Both ends of the connecting rod 23 are connected to the two guide components 14 respectively. The lifting mechanism and the punching mechanism are both mounted on the punching mounting rod 22. The drive assembly 3 is connected to the connecting rod 23 and can move back and forth along the feed direction of the plastic sheet 01 under the drive of the drive assembly 3.

[0055] The connecting rod 23 includes a crossbar 231 and a longitudinal bar 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 bar 232 is parallel to the feed direction of the plastic sheet 01. On the frame 11 of the machine frame 1, below the crossbeam 12, multiple guide rods 15 are mounted along the width direction of the plastic sheet 01. The length direction of the guide rods 15 is parallel to the feed direction of the plastic sheet 01. Each guide rod 15 passes through the crossbar 231 to guide the crossbar 231 to slide along the feed direction of the plastic sheet 01. One longitudinal bar 232 is connected to each end of the crossbar 231. Two sliders 21 are respectively installed on the upper side of the two crossbars 231. A guide hole 141 is opened on the guide component 14 along the feed 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 adjacent vertical rod 232.

[0056] The drive assembly 3 can be a cylinder, hydraulic cylinder, stepper motor, etc. In this embodiment, the drive assembly 3 is a cylinder, referred to as the first cylinder. The cylinder body of the first cylinder is mounted on the frame 11 of the frame 1, located upstream of the connecting rod 23 in the feeding direction of the plastic sheet 01. The piston rod of the first cylinder is horizontal, and its extension and retraction direction is parallel to the feeding direction of the plastic sheet 01. The end of the piston rod of the first cylinder is connected to the middle of the connecting rod 23. By extending and retracting the piston rod of the first cylinder, the connecting rod 23 can be driven to move along the feeding direction of the plastic sheet 01, thereby driving the entire feed frame 2 to move along the feeding direction of the plastic sheet 01.

[0057] The number of perforated mounting rods 22 can be one or more. When there is more than one perforated mounting rod 22, the stability of the component installed on it is better. Preferably, in this embodiment, there are two perforated mounting rods 22, which 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 spaced apart on the drilling mounting rod 22. Each connecting block 221 is slidably connected to the two drilling mounting rods 22, making the position of the connecting block 221 on the drilling mounting rod 22 adjustable, and each connecting block 221 can be limited by a pin or bolt. A mounting plate 222 is connected between the two upstream and downstream sides of the plastic sheet 01 in the feeding direction of each connecting block 221. A first lifting component 5 and a drilling limit gate 4 are mounted on each mounting plate 222. The first lifting component 5 and the drilling limit gate 4 are installed in the same way on both mounting plates 222.

[0059] The first lifting component 5 can be a cylinder, hydraulic cylinder, motor, or other similar components. In this embodiment, the first lifting component 5 is a cylinder, referred to as the second cylinder. The cylinder body of the second cylinder is located on the upper side of the mounting plate 222, and the piston rod extends and retracts vertically. The end of the piston rod of the second cylinder passes through the mounting plate 222 and connects to the perforated limit gate 4, thereby driving the perforated limit gate 4 to move up and down vertically.

[0060] The perforated limiting gate 4 is trapezoidal in shape and vertically positioned, with its length gradually increasing from top to bottom. The upper base of the perforated limiting gate 4 (corresponding to the shorter base of the trapezoid) is fixedly connected to the end of the piston rod of the second cylinder. Furthermore, the perforated limiting gate 4 has several weight-reducing holes 109 to reduce its weight. By making the perforated limiting gate 4 trapezoidal, with a longer lower base, it is used to extend into the irregular anchoring structure 02 to limit the plastic sheet 01, ensuring the limiting effect. The shorter upper base is used to connect to the second cylinder. Combined with the weight-reducing holes 109, this reduces the weight of the perforated limiting gate 4, decreases its inertia, and allows for faster and more accurate raising and lowering of the perforated limiting gate 4.

[0061] In other embodiments of the invention, if a mounting plate 222 and the second cylinder and the perforated limiting gate 4 thereon can effectively limit the plastic sheet 01, either of the two mounting plates 222 can be retained.

[0062] Please refer to Figure 3-5 A drilling mechanism is mounted on the feed frame 2 and is used to drill holes in the plastic sheet 01 vertically. The drilling mechanism can employ various standard and non-standard drilling equipment. Preferably, in this embodiment, the drilling mechanism includes a drilling cylinder 6 and a trimming cylinder 7. The piston rod of the drilling cylinder 6 is hollow. The drilling cylinder 6 includes a first cylinder body 61 and a first piston rod 62. The first cylinder body 61 is mounted on two drilling mounting rods 22. The first piston rod 62 extends and retracts vertically within the first cylinder body 61 and is hollow. A punching tool is provided 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 located at the upper end of the first cylinder body 61. The second piston rod 72 passes into the first piston rod 62 and can extend vertically from the end of the first piston rod 62. A trimming tool is provided at the end of the second piston rod 72.

[0063] To limit the movement of the plastic sheet 01 in its width direction and improve the accuracy of the drilling position and the quality of the drilling, the first cylinder 61 is provided with drilling limiting plates 63 on both sides of the plastic sheet 01 in the width direction. The drilling limiting plates 63 are vertically arranged, and their length or width direction is consistent with the feed direction of the plastic sheet 01. The thickness of the drilling limiting plates 63 is less than the interval between two adjacent rows of irregular anchoring structures 02 along the width direction of the plastic sheet 01. During the drilling and feeding of the plastic sheet 01, the drilling limiting plates 63 are always located between two adjacent rows of irregular anchoring structures 02 along the width direction of the plastic sheet 01, thereby limiting the movement of the plastic sheet 01 in its width direction.

[0064] The number of punching mechanisms can also be multiple, depending on the number of holes that need to be punched in the width direction of the plastic sheet 01. Each punching mechanism is installed in the same way.

[0065] It should be noted that when the first piston rod 62 and the second piston rod 72 extend or retract, they always pass between any two adjacent crossbeams 12 of the frame 1 without interfering with the crossbeams 12.

[0066] When the punching mechanism is working, the piston rod of the punching cylinder 6 moves vertically downwards first, and punches holes in the plastic sheet 01 using a punching tool. After punching is completed, the piston of the punching cylinder 6 retracts, and the piston of the trimming cylinder 7 moves vertically downwards again, and the trimming tool corrects the edge of the hole punched by the punching tool, thereby ensuring the quality of the punching mechanism.

[0067] Furthermore, the punching device of the present invention for the plastic sheet 01 with irregular anchoring structure 02 also includes a waste hopper (not shown in the figure). The waste hopper can be any suitable open container, which is set directly below the punching mechanism to collect the waste generated during punching, which is beneficial to the cleanliness of the production site and also to the recycling and reuse of waste.

[0068] The limiting mechanism includes a rotating shaft 8 and limiting wheels 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, each corresponding to a crossbeam 12. Each limiting wheel 81 is located above its corresponding crossbeam 12, and a gap is maintained between the limiting wheel 81 and the corresponding crossbeam 12 for the plastic sheet 01 to pass through. Furthermore, each limiting wheel 81 is located between two adjacent rows of irregularly shaped anchoring structures 02 along the width direction of the plastic sheet 01. The limiting wheel 81 can contact the plastic sheet 01, rotating as the plastic sheet 01 is fed. Alternatively, it can not contact the plastic sheet 01, but simply pass between two adjacent rows of irregularly shaped anchoring structures 02 along the width direction of the plastic sheet 01.

[0069] The limiting mechanism also includes a feed limiting gate 9 and a second lifting component 91. Both the feed limiting gate 9 and the second lifting component 91 are mounted 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 drives the feed limiting gate 9 to move up and down, so that the feed limiting gate 9 extends between two adjacent rows of irregularly shaped anchoring structures 02 along the feeding direction of the plastic sheet 01, or exits from between two adjacent rows of irregularly shaped anchoring structures 02 along the feeding direction of the plastic sheet 01.

[0070] The frame 1 also includes a gantry 13, which is fixed to the frame 11 and is C-shaped with its opening facing downwards. The width of the gantry 13 is the same as the width of the frame 11. The second lifting component 91 can be a cylinder, referred to as the third cylinder. The cylinder body of the third cylinder is located on the upper side of the gantry 13, and the piston rod extends and retracts vertically, passing through the gantry 13 and connecting to the feed limit gate 9. The feed limit gate 9 is trapezoidal in shape, similar to the shape of the perforation feed limit gate 9, and its length direction is parallel to the width direction of the plastic sheet 01. The upper bottom (shorter in length) of the feed limit gate 9 is connected to the feed limit gate 9, and the lower bottom, driven by the third cylinder, can extend into the space between two adjacent rows of irregularly shaped anchoring structures 02 along the feed direction of the plastic sheet 01, thus restricting the feed of the plastic sheet 01. Furthermore, the distance between the feed limit gate 9 and the drilling mechanism is greater than that between the drilling feed limit gate 9 and the drilling feed limit gate 9. It only serves to restrict the feeding of the plastic sheet 01. Therefore, its length is shorter than that between the drilling feed limit gate 9 to save materials.

[0071] There are multiple feed limit gates 9 and two lifting components 91, each corresponding to a specific one. 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 setting multiple feed limit gates 9 and second lifting components 91 along the feeding path of the plastic sheet 01, the movement of the plastic sheet 01 in its feeding direction can be more reliably restricted, thereby improving the drilling quality and accuracy of the drilling position of the drilling mechanism.

[0072] The welding mechanism includes a feeding assembly, a clamping assembly 102, and a welding component 103. The feeding assembly includes a receiving box 101. The receiving box 101 is mounted on the frame 1, located above the plastic sheet 01 with the irregular anchoring structure 02. Figure 9 As shown, both welded mounting rods 16 of the frame 1 pass through the housing 101, thereby realizing the installation of the housing 101.

[0073] Please refer to Figure 7-9 The receiving box 101 has a vertically oriented drop hole 1011. The diameter of the drop hole 1011 matches the diameter of the hot melt sheet 03, allowing one hot melt sheet 03 to pass through. The lower opening of the drop hole 1011 faces the plastic sheet 01. It should be noted that the drop hole 1011 does not interfere with the hole through which the welding mounting rod 16 passes through the receiving box 101. The clamping assembly 102 includes a telescopic component. The telescopic component is provided on the receiving box 101 and can pass vertically through the drop hole 1011 to clamp the hot melt sheet 03 onto the plastic sheet 01 with the irregular anchoring structure 02. The welding component 103 includes a hot melt gun. The hot melt gun is provided on the frame 1 and located below the plastic sheet 01, for heating the hot melt sheet 03 to weld the hot melt sheet 03 to the plastic sheet 01.

[0074] The feeding mechanism includes a feeder 104 and a hopper 105. The feeder 104 includes a housing 1041, a pushing component, and a connecting component 1045. The housing 1041 is rectangular and is fixedly connected to the receiving box 101 via the connecting component 1045, forming a feeding channel 10411 inside. The hopper 105 stores the hot melt sheet 03, is connected to the housing 1041, and communicates with the feeding channel 10411. A discharge port 10417 is formed on the side of the housing 1041 facing the welding mechanism, and the discharge port 10417 is the end of the feeding channel 10411. The connecting component 1045 is disposed between the housing 1041 and the receiving box 101, communicating the discharge port 10417 with the discharge hole 1011. The pushing component pushes the hot melt sheet 03 in the feeding channel 10411, causing it to enter the discharge hole 1011 from the feeding channel 10411.

[0075] Before welding, the part of the plastic sheet 01 to be welded is placed below the material drop hole 1011 of the receiving box 101. 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 material drop hole 1011, and then falls to the part of the plastic sheet 01 to be welded. After the telescopic component passes through the material drop hole 1011, it presses the hot melt sheet 03 firmly onto the plastic sheet 01. Finally, the hot melt gun heats the hot melt sheet 03 from below the plastic sheet 01, melting the hot melt sheet 03. After the hot melt sheet 03 cools, the welding is completed.

[0076] Specifically, the hot melt sheet 03 can be circular, square, or other shapes. However, in practical applications, circular hot melt sheets 03 weld most evenly and are more robust after welding. Therefore, as a preferred embodiment, the hopper 105 is cylindrical, forming a cylindrical storage space within it. The diameter of the storage space matches the diameter of the hot melt sheet 03. The storage space allows the hot melt sheets 03 to be stacked along their thickness direction. After the lower end of the hopper 105 is connected to the outer casing 1041, the storage space communicates with the feeding channel 10411, allowing the hot melt sheets 03 in the hopper 105 to fall into the feeding channel 10411 due to gravity.

[0077] The number of hot melt sheets 03 stored in the hopper 105 is related to the thickness of each hot melt sheet 03 and the height of the hopper 105. The higher the hopper 105 and the thinner the individual hot melt sheets 03, the more hot melt sheets 03 can be stored in the storage space. The number of hot melt sheets 03 stored in the hopper 105 of the feeder 104 should be sufficient to meet the welding needs of at least one roll of plastic sheet 01.

[0078] like Figure 10As shown, when there is only one hopper 105, a connection port, designated as the first connection port 10413, is provided on the upper side of the outer casing 1041. The hopper 105 is connected to the first connection port 10413. The vertical projection of the first connection port 10413 into the outer casing 1041 falls within the feeding channel 10411. The pushing assembly pushes the hot melt sheet 03 within the feeding channel 10411, thus pushing the hot melt sheet 03 out of the discharge port 10417.

[0079] like Figure 11 As shown, when there are two hoppers 105, two connection ports are opened on the upper side of the outer casing 1041, which are respectively referred to 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 into the outer casing 1041 both fall within the feeding channel 10411, and the second connection port 10414 is located between the first connection port 10413 and the discharge port 10417. Hot melt sheets 03 fall at both the first connection port 10413 and the second connection port 10414. When the pushing assembly pushes the hot melt sheet 03 below the first connection port 10413, it will push the hot melt sheet 03 below the second connection port 10414 out of the discharge port 10417. When the hot melt sheet 03 in the hopper 105 on the first connection port 10413 is consumed, the pushing component directly pushes the hot melt sheet 03 below the second connection port 10414 until the hot melt sheet 03 in the hopper 105 on the second connection port 10414 is consumed.

[0080] like Figure 12 As shown, when there are two hoppers 105, another scenario exists: two connection ports are opened on the upper side of the outer casing 1041, denoted as the second connection port 10414 and the third connection port 10415, respectively. The feeding channel 10411 extends to either side of its feeding direction to form a bypass channel 10412. The orthographic projection of the second connection port 10414 along the vertical direction within the outer casing 1041 falls within the feeding channel 10411. The orthographic projection of the third connection port 10415 along the vertical direction within the outer casing 1041 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 hopper 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 hopper 105 on the third connection port 10415 is consumed.

[0081] Since a roll of plastic sheet 01 is typically 50m or longer, two hoppers 105 are insufficient to supply the hot melt sheet 03. Therefore, please refer to... Figure 13In a preferred embodiment of the present invention, there are four hoppers 105. The feeding channel 10411 extends to either side of its feeding direction to form a bypass channel 10412. Four connection ports are provided on the upper side of the outer casing 1041, arranged in a square pattern. The four connection ports are a first connection port 10413, a second connection port 10414, a third connection port 10415, and a fourth connection port 10416. The vertical projections of the first connection port 10413 and the second connection port 10414 within the outer casing 1041 are located within the feeding channel 10411, with the second connection port 10414 located between the first connection port 10413 and the discharge port 10417. The vertical projections of the third connection port 10415 and the fourth connection port 10416 within the outer casing 1041 are both located within the bypass channel 10412, with the third connection port 10415 being 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. It can also push the hot melt sheet 03 below the third connection port 10415 to the bottom of the second connection port 10414 and the hot melt sheet 03 below the fourth connection port 10416 to the bottom of the first connection port 10413 in a direction that is horizontal and perpendicular to the feeding direction.

[0082] In practical applications, the hot melt sheet 03 in the hopper 105 on the second connection port 10414 is consumed first, and then the hot melt sheet 03 in the hopper 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 hoppers 105 can be more than four. Their working principle is similar to that of the case where there are four hoppers 105, and will not be repeated here.

[0084] It should also be noted that the heights of the feeding 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 feeding channel 10411 and the bypass channel 10412 are sufficient to accommodate two or more stacked hot melt sheets 03, feeding can still be performed, but the hot melt sheets 03 may become obstructed in the feeding channel 10411 or the bypass channel 10412 due to tilting, affecting welding efficiency. Therefore, in a preferred embodiment of the present invention, the heights of the feeding 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. In this case, the feeding 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 pushing component can be an electric actuator, a pneumatic cylinder, a hydraulic cylinder, or other similar components. Since electric actuators have advantages such as small size, high precision, and ease of installation, this embodiment uses an electric actuator as the pushing component.

[0086] Please refer to Figure 13 There are four in silo 105, and as Figure 13 In the arrangement shown, there are three electric actuators: a first electric actuator 1042, a second electric actuator 1043, and a third electric actuator 1044. The first electric actuator 1042 extends into the feeding channel 10411 along the feeding direction to push the hot melt sheet 03 below the first connection port 10413, thereby pushing the hot melt sheet 03 below the second connection port 10414 out of the discharge port 10417, or directly pushing the hot melt sheet 03 below the first connection port 10413 out of the discharge port 10417. The second electric actuator 1043 extends into the bypass channel 10412 in a horizontal direction perpendicular to the feeding direction, and pushes the hot melt sheet 03 below the fourth connection port 10416 below the first connection port 10413. The push rod of the third electric push rod 1044 extends into the bypass channel 10412 in a horizontal direction and perpendicular to the feeding direction, and is used to push the hot melt sheet 03 below the third connection port 10415 to below the second connection port 10414.

[0087] By cooperating with the electric actuator and the hopper 105, the hot melt sheet 03 in the hopper 105 can be quickly fed into the welding mechanism, thereby improving the efficiency of the welding operation.

[0088] Please continue to participate. Figure 7-9 The receiving box 101 is rectangular in shape. A material discharge hole 1011 is vertically located in the middle of the receiving box 101. The connecting component 1045 is also rectangular in shape, with a connecting channel 10451 formed inside. One side opening of the connecting channel 10451 communicates with the discharge port 10417, and the other side opening is located in the middle of the inner wall of the material discharge hole 1011 and communicates with the discharge hole 1011. After the hot melt sheet 03 is pushed out from the discharge port 10417, the push rod of the electric actuator continues to push the hot melt sheet 03, causing it to enter the material discharge hole 1011. Finally, under the action of gravity, it falls from the material discharge hole 1011 to the position where the plastic sheet 01 needs to be welded.

[0089] The clamping assembly 102 can be a clamping cylinder, with the cylinder body positioned on the upper side of the receiving box 101. The piston rod extends vertically into the material discharge hole 1011, and its stroke is sufficient to clamp the hot melt sheet 03 onto the surface of the plastic sheet 01. In other embodiments of the present invention, the clamping assembly 102 may also be a suitable component such as a cylinder or a motor lead screw.

[0090] Please refer to Figure 7 , Figure 14The hot melt gun uses electric heating. By connecting to a power source, its upper end generates high temperatures, 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 sufficiently melted for welding, the hot melt gun should stop heating to prevent overheating and damage. However, even after the power is turned off, the upper end of the hot melt gun retains residual heat, preventing immediate cessation of heating. Therefore, to avoid overheating 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 mounted on the frame 1, and the piston rod extends and retracts vertically. The end of the piston rod of the lifting cylinder is fixedly connected to the hot melt gun to move the hot melt gun 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 raises the hot melt gun, bringing its upper end close to the hot melt sheet 03 and the plastic sheet 01 for welding. Once the hot melt sheet 03 and the plastic sheet 01 have melted sufficiently for welding, the lifting cylinder lowers the hot melt gun away from the hot melt sheet 03 and the plastic sheet 01, preventing damage due to over-melting. This further improves the welding quality of the hot melt sheet 03.

[0092] Furthermore, if multiple hot melt sheets 03 need to be welded to the plastic sheet 01 at intervals along its width direction, multiple welding mechanisms are spaced apart on the frame 1 along the width direction of the plastic sheet 01 with the irregular anchoring structure 02. Multiple feeding mechanisms and welding mechanisms are also spaced apart on the frame 1 along the width direction of the plastic sheet 01, corresponding one-to-one. To ensure welding efficiency, each feeding mechanism and welding mechanism operates synchronously. Figure 6 , Figure 7 The diagram shows the case where both the feeding mechanism and the welding mechanism have six components.

[0093] Please refer to Figure 7-9 If the position of the plastic sheet 01 shifts during the welding process between the hot melt sheet 03 and the plastic sheet 01, the welding quality will deteriorate, or even the welding will fail. To reduce the positional shift of the plastic sheet 01 during the welding operation, the device of the present invention further includes a limiting assembly. The limiting assembly includes a welding limiting plate 107, a driving component 110, and a welding limiting gate 108.

[0094] The welding limiting plate 107 is vertically positioned and disposed on one or both sides of the receiving box 101 along the width direction of the plastic sheet 01 with the irregular anchoring structure 02. The length direction of the welding limiting plate 107 is consistent with the length direction of the plastic sheet 01, and extends between two adjacent rows of irregular anchoring structures 02 along the width direction of the plastic sheet 01, restricting the displacement of the plastic sheet 01 in its width direction. However, the welding limiting 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] A drive component 110 is mounted on the telescopic component and connected to the welding limit gate 108, used to drive the welding limit gate 108 to move up and down vertically. In this embodiment, the drive component 110 is a drive cylinder. When there is only one feeding mechanism, one drive cylinder is provided on each side of the receiving box 101 along the length of the plastic sheet 01. When there are multiple feeding mechanisms, one mounting plate 222 is installed on each side of two adjacent receiving boxes 101 near the middle of the plastic sheet 01 along the length of the plastic sheet 01. One drive cylinder is installed on each of the two mounting plates 222. The piston rod of the drive cylinder moves up and down vertically.

[0096] The welded limiting gate 108 is vertically arranged, and its length direction is consistent with the width direction of the plastic sheet 01. The welded limiting gate 108 can extend into the plastic sheet 01 between two adjacent rows of irregular anchoring structures 02 along its length direction, limiting the displacement of the plastic sheet 01 with irregular anchoring structures 02 in its length direction.

[0097] One welding limit gate 108 is installed on each of the two drive cylinders, and the two welding limit gates 108 are installed in the same way. Specifically, the welding limit gate 108 is a trapezoidal plate, with one side serving as the upper base of the trapezoid connected to the end of the piston rod of the corresponding drive cylinder, and the other side serving as the lower base of the trapezoid extending into the space between two adjacent rows of irregularly shaped anchoring structures 02 along the length of the plastic sheet 01. 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, several weight-reducing holes 109 can also be opened on the welding limit gate 108.

[0098] When the plastic sheet 01 is placed in the predetermined position for welding, the two drive cylinders respectively drive the two welding limit gates 108 to fall, limiting the displacement of the plastic sheet 01 along its length, which helps to improve the quality of the welding operation. After the welding operation is completed, when it is necessary to change positions or remove the plastic sheet 01, the two drive cylinders respectively drive the two welding limit gates 108 to rise.

[0099] Please refer to Figure 15Based on the aforementioned equipment for drilling and welding plastic sheets with irregular anchoring structures, this invention discloses a method for producing plastic sheets with fasteners, the method comprising the following steps:

[0100] S1. Place the plastic sheet 01 on the working surface of the equipment frame 1 for drilling and welding the plastic sheet 01 with the irregular anchoring structure 02, with the side with the irregular anchoring structure 02 facing upwards.

[0101] S2. Drive the feed frame 2 through the drive component 3 to feed the plastic sheet 01 so that the parts to be processed pass 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 a hole in the plastic sheet 01; when the part to be processed reaches the welding station of the welding mechanism, the welding mechanism welds the fastener to the hole punched by the punching mechanism.

[0103] S3. Repeat step S2 until all the parts to be processed on the plastic sheet 01 are completed.

[0104] Compared with existing technologies, the above methods can produce plastic sheets with fasteners more efficiently and with higher quality.

[0105] When the spacing between two adjacent rows of parts to be processed along the feed direction on a plastic sheet is not the same, although it can improve production efficiency and quality compared with the existing technology, the drilling mechanism and the welding mechanism cannot work at the same time because when one row of parts to be processed is at the welding station of the welding mechanism, the adjacent row of parts to be processed upstream in its feed direction is not at the drilling station of the drilling mechanism.

[0106] Therefore, in this preferred embodiment, along the feeding direction of the plastic sheet 01, the parts to be processed are sequentially the first part to be processed, the second part to be processed, ..., the nth part to be processed; the interval between the punching station of the punching mechanism and the welding station of the welding mechanism is the same as the distance between two adjacent parts to be processed.

[0107] Step S2 specifically includes:

[0108] The drive assembly 3 drives the feed 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 feeds the second part to be processed to the drilling station of the drilling mechanism.

[0109] The fastener is welded to the first part to be processed by the welding mechanism, and a hole is punched in the second part to be processed by the drilling mechanism.

[0110] The drive assembly 3 drives the feed 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 feeds the third part to be processed to the drilling station of the drilling mechanism.

[0111] The fastener is welded to the second part to be processed by the welding mechanism, and a hole is punched in the third part to be processed by the drilling mechanism.

[0112] ...

[0113] The drive assembly 3 drives the feed 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 feeds the (n+1)th part to be processed to the punching station of the punching mechanism.

[0114] The fastener is welded to the nth part to be processed by the welding mechanism, and a hole is punched at the (n+1)th part to be processed by the drilling mechanism.

[0115] It should be noted that in step S3, n is a natural number greater than or equal to 2. After the nth part to be processed is welded, if the nth part to be processed is the last part to be processed, it means that this is the end of the plastic sheet 01, and there is no (n+1)th part to be processed. Therefore, the drilling mechanism does not need to work anymore.

[0116] During welding, the hot melt sheet 03 required for welding is supplied through the material hopper 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 actuator 1042, the second electric actuator 1043, and the third electric actuator 1044 push the hot melt sheet 03 in the material supply channel 10411 of the housing 1041 into the discharge hole 1011 of the receiving box 101. The hot melt sheet 03 falls onto the part to be processed due to gravity along the discharge hole 1011. The clamping assembly 102 clamps the hot melt sheet 03 onto 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, the number of hoppers 105 can be one or more, based on the number of fasteners required to weld one fastener to each processing location on the plastic sheet 01. The cases where the number of hoppers 105 is one, two, or four are all described in detail in the above description of the equipment for drilling and welding the plastic sheet 01 with the irregular anchoring structure 02; the appropriate selection can be made when implementing step S2.

[0118] On the other hand, in order to ensure the quality of drilling and welding, the plastic sheet 01 needs to be limited during the drilling process of the drilling mechanism and the welding process of the welding mechanism.

[0119] Specifically, in step S2, when the punching mechanism is punching, the punching limit gate 4 is in a lowered state, restricting the displacement of the plastic sheet 01 in its feed direction. After the punching mechanism completes punching, the punching limit gate 4 remains in the lowered state, and the drive assembly 3 drives the feed frame to the welding station of the welding mechanism, feeding 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 the raised state, disengaging from the plastic sheet 01, and the drive assembly 3 drives the feed frame to retreat to the next part to be processed, and the punching limit gate 4 switches to the lowered state.

[0120] During the process of welding the fastener to the part to be processed, the welding limit gate 108 is in a descending state, which restricts the displacement of the plastic sheet 01 in its feed direction.

[0121] Except for the drilling limit gate 4 and the welding limit gate 108, during the drilling process of the drilling mechanism and the welding process of the welding mechanism, the feed limit gate 9 is in a lowered state, restricting the displacement of the plastic sheet 01 along its feed direction. When the drive assembly 3 drives the feed frame to feed, the feed limit gate 9 is in a raised state, releasing the plastic sheet 01.

[0122] By cooperating with the drilling 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 drilling and welding process can be restricted, thus ensuring the quality of the drilling and welding operations.

[0123] To further improve the quality of drilling and welding operations, when the drilling mechanism drills holes in the area to be processed, the first piston rod 62 of the drilling cylinder 6 extends first to drill holes in the plastic sheet 01. Then, the second piston rod 72 of the trimming cylinder 7 extends to trim the edges of the holes drilled by the first piston rod 62. This ensures that the edges of the holes drilled by the drilling mechanism are neat, allowing for uniform melting and thus a firm weld to the hot melt sheet 03.

[0124] Furthermore, before and after welding, the hot melt gun is driven away from the hot melt sheet 03 by the third lifting component 106. When welding, the hot melt gun is first driven closer 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 melt welded. 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 plastic sheets with fasteners of the present invention, by using equipment for drilling and welding plastic sheets with irregular anchoring structures, can produce plastic sheets with fasteners efficiently and with high quality.

[0126] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
