Description

[0001] This application is a divisional application of the Chinese patent application submitted to the China Patent Office on July 17, 2024, with application number 202410959673.3 and invention name "Pipeline laying process based on heating blanket". Technical Field

[0002] The present invention relates to the technical field of heating blanket processing, and in particular to a pipeline laying process based on a heating blanket. Background Art

[0003] A heating blanket provides warmth and consists of an upper blanket, a lower blanket, and the wiring between them. Heating blankets are categorized as either electric or water-heated. The wiring in electric blankets consists of heating wires, which release heat when energized. In water-heated blankets, the wiring consists of water pipes, which release heat through hot water. To create a heating blanket, the wiring is first laid on the lower blanket. The upper and lower blankets are then joined together, sandwiching the wiring between them.

[0004] In the existing technology, the lower blanket is usually laid first. Then, from the bottom of the lower blanket, many positioning pins are passed upward through the lower blanket. The pipelines are then passed around the positioning pins and hooked on them. After the pipelines are placed, all the positioning pins are lowered, and then the upper blanket is laid. The disadvantages of this method are that the positioning pins can easily cause the lower blanket to deform when passing through them. Moreover, during the laying process, the pipelines are only hooked on the positioning pins, and they often become detached from the positioning pins, requiring workers to repair them. This operation is cumbersome and inefficient. Summary of the Invention

[0005] The present invention provides a pipeline laying process based on a heating blanket, so as to solve the technical problems in the prior art that the lower blanket is easily deformed and the pipeline is easily separated from the positioning needle.

[0006] To solve the above problems, according to a first aspect of the present invention, the present invention provides a pipeline laying process based on a heating blanket, which adopts the following technical solution: the pipeline laying process based on a heating blanket comprises the following steps: S1, applying glue on the outside of the pipeline to be laid; S2, laying the glued pipeline along the set route and pressing it on the lower blanket so that the pipeline is bonded to the lower blanket.

[0007] According to a second aspect of the present invention, a pipeline laying process is provided, wherein a pipeline is laid and fixed on a lower blanket according to a set route, comprising the following steps: S1, while the pipeline to be laid is laid on the lower blanket according to the set route, glue is applied to the outside of the pipeline to fix it on the lower blanket; S2, while applying glue to the outside of the pipeline to fix it on the lower blanket, the glued pipeline is laid along a set route and compacted on the lower blanket so that the pipeline is bonded to the lower blanket.

[0008] The beneficial effect is that the pipeline is fixed to the lower blanket by first applying glue to the outside of the pipeline and then pressing it onto the lower blanket, or by applying glue while laying the line and compacting it, and the connection between the pipeline and the lower blanket is ensured by the viscosity of the glue itself. Compared with the prior art method of inserting positioning pins into the lower blanket and hanging the pipeline on the positioning pins, the pipeline laying process of the present invention will not cause damage or deformation to the lower blanket. At the same time, the bonding method is relatively strong, and the pipeline will not move. Workers do not need to perform remedial work, which saves remedial time and improves the efficiency of pipeline laying. In the pipeline laying process of the present invention, it is only necessary to apply glue to the pipeline, and there is no need to apply glue to the entire lower blanket. The amount of glue used is also relatively small.

[0009] Furthermore, in S1, glue is sprayed toward one side of the pipeline through a glue spraying head, and in S2, the glue-sprayed side of the pipeline is pressed onto the lower blanket.

[0010] Furthermore, in S2, the pipeline is pressed onto the lower blanket by a pressure wheel having a wheel groove, and the pipeline is inserted into the wheel groove of the pressure wheel. The pipeline is laid on the lower blanket by driving the pressure wheel to rotate and reverse around an axis extending up and down and driving the pressure wheel to move according to the set route.

[0011] Furthermore, the glue spray head and pressure roller are mounted on the bottom of the same wiring head. The wiring head is rotatably mounted on a mounting base around an axis extending vertically. The wiring head has a through-hole extending vertically, through which the pipeline extends from top to bottom. The wiring head is driven to rotate, thereby driving the pressure roller to rotate and reverse direction as it moves along the set route. The mounting base is driven up and down by a drive mechanism to press the pressure roller onto the lower carpet. At the same time, the mounting base is driven to move in a horizontal plane by the drive mechanism, thereby causing the pressure roller to move along the set route. The glue spray head and pressure roller are mounted on the bottom of the same wiring head, and the pipeline extends downward through the through-hole of the wiring head. By rotating the wiring head, the overall direction of the glue spray head and pressure roller can be reversed, so that the glue spray head is always located in front of the pressure roller during use, and the glue is sprayed first and then the pipeline is pressed.

[0012] Furthermore, the driving mechanism includes a telescopic component connected to the mounting seat, the telescopic component drives the mounting seat to move up and down, and the driving mechanism also includes a translation component that drives the telescopic component to move in the horizontal direction.

[0013] Furthermore, the telescopic component is mounted on the translation component in an adjustable manner in the up and down directions.

[0014] Furthermore, the translation component includes a slide that can move in the horizontal direction, a C-shaped seat is fixed on the slide, the telescopic component is assembled on the C-shaped seat in an up and down sliding direction, and the C-shaped seat is also provided with a screw rod for driving the telescopic component to rise and fall.

[0015] Furthermore, an annular groove is provided on the outer peripheral surface of the wiring head, a glue outlet channel connecting the annular groove and the glue spraying head is provided in the wiring head, and a glue inlet channel connected to the annular groove is provided in the mounting seat. The glue inlet channel, the annular groove and the glue outlet channel are used to ensure that the glue spraying head can spray glue after rotating and reversing.

[0016] Furthermore, after the pipeline passes through the wiring head and before entering the pressure wheel, the pipeline is guided by the guide wheel, which is located above the pressure wheel and has a wheel groove for the pipeline to enter.

[0017] Furthermore, a limiting block is arranged above the pressure wheel, and a limiting groove is provided in the limiting block. After the pipeline passes through the wiring head, it first enters the limiting groove of the limiting block and then enters the wheel groove of the pressure wheel. The limiting groove limits the pipeline in the axial direction of the pressure wheel, so that the pipeline enters the wheel groove of the pressure wheel accurately.

[0018] In the second aspect of the present invention, the process efficiency is greatly improved due to the simultaneous gluing, routing and compacting. A standard-sized electric blanket can be laid in less than one minute.

[0019] In the second aspect of the present invention, since the fully automated operation of gluing, routing and compacting is achieved, personalized design can be carried out according to different needs, and the same machine tool can be used to achieve the personalized design. For example, the same machine tool can be used to produce heating blankets for adults and heating blankets for children, and it is only necessary to design the routing path to meet the needs of various models.

[0020] In the second aspect of the present invention, since the simultaneous gluing, routing and compacting can be personalized according to different needs, a DIY routing pattern paving path can be achieved.

[0021] In the second aspect of the present invention, since the glue is applied, the lines are laid, and the compaction is carried out at the same time, there is no need to apply full glue on the lower carpet surface, which greatly saves the amount of glue used. Compared with the full glue coating mode, the possibility of glue seeping into the skin is greatly reduced.

[0022] In the second aspect of the present invention, since the glue is applied, the wire is routed and the compaction is carried out simultaneously, the wire entanglement and wire jumping phenomena that are often formed in existing machine tools will not occur. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0028] Figure 1 Schematic diagram of the structure of the pipeline laying device used in the pipeline laying process based on the heating blanket of the present invention; Figure 2 、 Figure 3 The three-dimensional and front views of the wiring mechanism, cylinder, and first C-shaped seat are shown respectively. Figure 4 This is a partial enlarged view of the glue spray head. Figure 5 A cross-sectional view of its fixing seat and wiring head.

[0029] In a specific embodiment of the present invention, the pipeline laying process of the present invention may use the following Figures 1 to 5 The pipeline laying device includes a routing mechanism 200 and a drive mechanism 100. The routing mechanism 200 applies glue to the pipeline 300 and presses the glued pipeline 300 onto the underlying carpet. The drive mechanism 100 drives the routing mechanism 200 and the pipeline 300 horizontally along a set route and simultaneously drives the routing mechanism 200 up and down. When descending, the routing mechanism 200 presses the pipeline 300 onto the underlying carpet.

[0030] The driving mechanism 100 includes a translation component and a telescopic component. The translation component includes a frame, and two mutually parallel first guide rails 101 are provided on the frame. For the convenience of description, the first guide rails 101 are defined as extending in the front-to-back direction, and the two first guide rails 101 are arranged at intervals in the left-to-right direction. The driving mechanism 100 also includes a second guide rail 102 extending in the left-to-right direction. The second guide rail 102 is mounted on the two first guide rails 101 and can slide in the front-to-back direction. The driving mechanism also includes a slide 103 slidably assembled on the second guide rail 102 in the left-to-right direction. Among them, the method of driving the second guide rail 102 and the slide 103 to slide can adopt common methods such as a screw-nut mechanism, which will not be repeated here.

[0031] A first C-shaped seat 104 is fixedly mounted on the slide 103. The opening of the first C-shaped seat 104 faces the horizontal side. A lead screw 105 is rotatably mounted inside the seat. A guide rod 106 is also fixedly mounted thereon. The lead screw 105 and the guide rod 106 are parallel to each other and extend vertically. A first servo motor 108 is also mounted above the first C-shaped seat 104. The first servo motor 108 is connected to the lead screw 105 to drive the lead screw 105 to rotate.

[0032] The telescopic component includes a slider 107 that is sleeved on the outside of the screw rod 105 and the guide rod 106. The screw rod 105 is threadedly engaged with the slider 107 to drive the slider 107 to slide up and down. A cylinder 109 is fixedly mounted on the slider 107. The cylinder 109 includes a cylinder body mounted on the slider 107 and a piston rod extending upward.

[0033] like Figures 2 to 5 As shown, the wiring mechanism 200 includes a mounting base fixed to the piston rod. The mounting base includes an L-shaped base 201. The L-shaped base 201 comprises a horizontal plate and a vertical plate fixedly connected to each other. The horizontal plate is directly connected to the piston rod, and the vertical plate is located below the horizontal plate. A reinforcing plate 215 is also fixedly mounted on the bottom of the horizontal plate. The reinforcing plate 215 is mounted on the outside of the cylinder body in a vertically sliding direction. The cooperation between the reinforcing plate 215 and the cylinder body can improve the stability of the mounting base 201 during lifting and lowering.

[0034] The mounting base also includes a mounting base 207 fixedly mounted on the side of the vertical plate facing away from the horizontal plate. A central hole extending vertically through the mounting base 207 is formed, and a wiring head 209 is rotatably mounted in the central hole. The wiring head 209 is rotatable about an axis extending vertically. A reversing drive component is mounted on the mounting base to drive the wiring head 209. Specifically, the wiring head 209 includes a small-diameter portion located at the top and a large-diameter portion located at the bottom. The small-diameter portion is inserted into the central hole of the mounting base 207, and the upper end of the small-diameter portion is inserted through the upper end of the mounting base 207. The reversing drive component includes a second U-shaped seat 202 installed on the horizontal plate, and the opening of the second U-shaped seat 202 faces the fixed seat 207; the reversing drive component includes a second servo motor 203 fixedly installed on the top of the second U-shaped seat 202, and the motor shaft of the second servo motor 203 passes through the second U-shaped seat 202, and a first pulley 204 is fixedly installed on the motor shaft, and a second pulley 205 is fixedly installed on the upper end of the small diameter part of the wiring head 209, and the first pulley 204 and the second pulley 205 are connected by a synchronous belt 206, so that the second servo motor 203 can drive the wiring head 209 to rotate.

[0035] A through hole 220 is formed at the center of the wiring head 209 and passes through the through hole 220 from top to bottom.

[0036] A pressure roller 213 is rotatably mounted at the lower end of the wiring head 209. The axis of rotation of the pressure roller 213 extends horizontally, and a groove is defined in the center of the pressure roller 213 for the pipeline 300 to fit into. Specifically, lugs 210 are mounted on either side of the large-diameter portion of the wiring head 209, and the pressure roller 213 is rotatably mounted between the two lugs 210. A guide roller 212 is also rotatably mounted between the two lugs 210. The guide roller 212 is located above the pressure roller 213 and has a groove in the center for the pipeline 300 to fit into. In actual use, bearings are mounted on the lugs 210, and the central axes of the pressure rollers 213 and guide rollers 212 are inserted into the bearings. Both the pressure roller 213 and the guide roller 212 are unpowered driven wheels. When the wiring mechanism 200 is driven horizontally by the drive mechanism 100, if the pressure roller 213 presses against the lower carpet, the pressure roller 213 will rotate.

[0037] After passing downward through the wiring head 209, the pipeline 300 passes through the guide wheel 212 and the pressure wheel 213 in sequence. The pressure wheel 213 presses the pressure wheel 213 toward the lower carpet as it moves. To limit the position of the pipeline 300 entering the pressure wheel 213 in the axial direction, a limit block 214 is fixedly installed between the two ear plates 210. The limit block 214 has a limit groove 216 extending vertically therethrough. The limit groove 216 has two side walls. The pipeline 300 passes downward through the limit groove 216, and the two side walls form a stop for the pipeline 300.

[0038] The wiring mechanism 200 also includes a glue spray head 211 mounted at the bottom of the wiring head 209. The glue spray head 211 sprays glue onto the side of the pipeline 300, which is used to press against the lower carpet. The glue spray head 211 rotates with the wiring head 209. The glue spray head 211 is located on one side of the perforation 220. The glue spray head 211 is generally arranged from top to bottom and tilted toward the pipeline 300, capable of spraying glue onto the pipeline 300. The glue spray head 211 is located above the pressure wheel 213, so that the pipeline 300 is first sprayed with glue and then pressed against the lower carpet by the pressure wheel 213, where it is bonded and fixed to the lower carpet. In other words, in a preferred embodiment of the present invention, glue is sprayed onto the exterior of the pipeline 300.

[0039] An annular groove 217 is formed on the outer circumference of the small-diameter portion of the wiring head 209. A glue outlet channel 218 is formed within the wiring head 209, connecting the glue dispenser 211 with the annular groove 217. The glue outlet channel 218 can be an inclined channel or formed by connecting multiple straight channels. A glue inlet channel 219 is formed on the fixing base 207, connecting to the annular groove 217. The glue inlet channel 219 extends horizontally, allowing the glue in the glue inlet channel 219 to enter the annular groove 217 even if the wiring head 209 rotates relative to the fixing base 207.

[0040] A pneumatic valve 208 is mounted on one side of the mounting base 207. The outlet of the pneumatic valve 208 is connected to the glue inlet passage 219, and the inlet of the pneumatic valve 208 is connected to the rubber hose. Compressed air can open or close the pneumatic valve 208, thereby controlling whether glue enters the glue inlet passage 219. In actual use, a pump is installed on the rubber hose to pressurize the glue liquid.

[0041] During use, the pipeline 300 passes through the through-hole 220 of the wiring head 209 from top to bottom, passes around the guide wheel 212 and the pressure wheel 213 in sequence, and then extends to the bottom of the pressure wheel 213. In S1, the glue spraying head 211 sprays glue onto the pipeline 300. In S2, the pressure wheel 213 is driven by the drive mechanism 100 to press the pipeline 300 onto the lower layer of carpet. When reversing is required, the second servo motor 203 is activated, driving the wiring head 209, the glue spraying head 211, the guide wheel 212, and the pressure wheel 213 to reverse direction together. The pressure wheel 213 clamps the pipeline 300 to reverse direction, achieving continuous laying.

[0042] In the above embodiment, glue is sprayed onto the exterior of the pipeline 300 using the glue spray head 211. This is to form a layer of glue on the exterior of the pipeline 300 before the pipeline 300 is pressed onto the lower blanket. To achieve this, other methods such as roller coating or dip coating can be used in other embodiments. For example, a container storing glue is provided, and the pipeline passes through the container, whereupon the exterior is coated with glue before being pressed onto the lower blanket by a pressing roller.

[0043] In the above embodiment, the pipeline 300 is pressed against the lower blanket using a pressure wheel 213. The pressure wheel 213 is driven to move by the drive mechanism 100, and the reversal of the pressure wheel 213 ensures that the pipeline 300 is first coated with glue and then pressed. In other embodiments, the pipeline layout and downward pressure can be arranged on two devices. The downward pressure device can be implemented in the following manner: a robot is arranged on one side of the lower blanket, and a pressure plate is mounted on the robot's mechanical arm. The pressure plate moves along the pipeline laying route. During pipeline laying, the glued pipeline extends below the pressure plate, and the pressure plate presses the pipeline and then moves, pressing the pipeline against the lower blanket as it moves.

[0044] The above is a detailed explanation of the pipeline laying device used in the pipeline laying process based on the heating blanket in the specific embodiment of the present invention. The pipeline laying process of the present invention will be described in detail below in combination with specific embodiments. Those skilled in the art understand that although the present invention is described using a heating blanket as an example, the process can actually be used for laying pipelines in water heating blankets or other similar application scenarios. The electric blanket mentioned in the present invention refers to a similar item in a broad sense that requires laying pipelines including electric heating wires on a layer including the blanket surface. The present invention is not limited to the specific embodiment.

[0045] Example 1

[0046] Figure 6 The figure is a process flow chart of the pipeline laying process based on the heating blanket of the present invention.

[0047] like Figure 6As shown, the purpose of the pipeline laying process based on the heating blanket of the present invention (hereinafter referred to as the pipeline laying process) is to lay and fix the pipeline on the lower blanket according to a set route, ensuring that the pipeline and the lower blanket are reliably fixed together.

[0048] The heating blanket can be either an electric blanket or a water heating blanket, and the corresponding pipeline can be either an electric heating wire or a water pipe.

[0049] The pipeline laying process includes the following steps: S1. While the pipeline 300 to be laid is laid on the lower carpet according to a set route using a routing mechanism, a glue spraying mechanism is used to apply glue to the outer portion of the pipeline where it contacts the lower carpet to secure it to the lower carpet. In this first embodiment, the routing mechanism is routing mechanism 200, and the glue spraying mechanism is implemented by a glue spraying head 211 disposed on routing mechanism 200. While the simultaneous actions described herein are most preferably performed strictly simultaneously, this also includes the glue spraying being performed slightly before the laying action, or completing the glue spraying action immediately before the laying action. However, it is best to ensure that the glue spraying action is performed no later than the laying action. Even if the glue spraying action is delayed by 0.01 seconds, it may result in undesirable glue smearing, causing the pipeline to be laid loose and shift.

[0050] In a preferred embodiment, assuming that the initial laying point of the pipeline 300 on the lower carpet is recorded as P0, glue spraying starts at point PO, and the laying points at the next moment are recorded as P1, P2..., and so on. The laying point at a certain moment t is recorded as Pt, then the position of the glue spraying point at any of the above moments t almost coincides with the position of the above laying point, which is also Pt. In a more preferred embodiment, the adjacent intervals between P1, P2..., Pt are equal. In a further preferred embodiment, the adjacent intervals between P1, P2..., Pt tend to zero, that is, the glue spraying action realizes continuous glue dispensing.

[0051] S2: While applying glue to the exterior of the pipeline 300 to secure it to the lower blanket, the glued pipeline is laid along a predetermined path and compacted onto the lower blanket using the pressing wheel 213, ensuring that the pipeline 300 is firmly bonded to the lower blanket. This adhesive bonding secures the pipeline 300 to the lower blanket, preventing separation between the lower blanket and the pipeline 300 and preventing deformation of the lower blanket.

[0052] After the pipeline 300 is laid, coated and compacted, the upper blanket surface is pressed onto the lower blanket surface to form a finished heating blanket.

[0053] In this embodiment, the glue applied is not particularly limited, as long as it can firmly secure the pipeline to the underlying blanket. In a preferred embodiment, the glue is heat-resistant. For electric blankets, the heating wires, which serve as pipelines, continuously heat up during operation, causing the pipeline temperature to rise. Using heat-resistant glue can significantly increase the stability of the glue points, thereby extending the lifespan of the electric blanket. In a further preferred embodiment, the glue is colorless and odorless. It is worth noting that, given the increasing consumer demand for environmental protection, the glue is environmentally friendly.

[0054] In this embodiment, the process efficiency is greatly improved because the glue is applied, the line is laid, and the compaction is carried out simultaneously. A standard-sized electric blanket can be laid in less than one minute.

[0055] In this embodiment, since the fully automated operation of gluing, routing and compacting is achieved, personalized design can be carried out according to different needs, and the same machine tool can be used to achieve the personalized design. For example, the same machine tool can be used to produce heating blankets for adults and heating blankets for children, and it is only necessary to design the routing path to meet the needs of various models.

[0056] In this embodiment, since the simultaneous gluing, routing, and compacting can be personalized according to different needs, a DIY routing pattern paving path can be achieved.

[0057] In this embodiment, since glue is applied, wired, and compacted simultaneously, there is no need to apply full glue on the lower carpet surface, which greatly saves the amount of glue used. Compared with the full glue coating mode, the possibility of glue seepage and contact with the skin is greatly reduced (from 100% to 0.1%), providing a full skin-friendly experience.

[0058] In this embodiment, because glue is applied, wires are routed, and compacted simultaneously, the wire tangles and jumpers common in existing machine tools are eliminated. These problems, which require machine shutdown and time-consuming wiring head removal, are eliminated. Voltage instability is common during machine operation, but with the process of this embodiment, even with voltage instability, wire tangles and jumpers have never occurred.

[0059] Example 2

[0060] The pipeline laying process includes the following steps: S1. While the pipeline 300 to be laid is laid on the lower carpet according to a predetermined route using a routing mechanism, a roller coating mechanism is used to apply glue to the outer portion of the pipeline where it contacts the lower carpet to secure it to the lower carpet. In this first embodiment, the routing mechanism is routing mechanism 200, and the roller coating mechanism is implemented using a roller (not shown) mounted on routing mechanism 200. While the simultaneous operation described herein is most preferably performed simultaneously with the laying and roller coating, it is also possible to perform the roller coating slightly before the laying, or to complete the roller coating immediately before the laying. However, it is best to ensure that the roller coating is no later than the laying operation. Even if the glue spraying operation is delayed by 0.01 seconds, it may result in undesirable glue slurry, causing the pipeline to be laid loose and shift.

[0061] In a preferred embodiment, it is assumed that the initial laying point of the pipeline 300 on the lower carpet is recorded as P0, and gluing begins at point PO. The laying points at the next moment are recorded as P1, P2..., and so on. The laying point at a certain moment t is recorded as Pt. Then the position of the gluing point at any of the above moments t almost coincides with the position of the above laying point, which is also Pt. In a more preferred embodiment, the adjacent intervals between P1, P2..., Pt are equal. In a further preferred embodiment, the adjacent intervals between P1, P2..., Pt tend to zero, that is, the gluing action realizes continuous gluing.

[0062] S2: While applying glue to the exterior of the pipeline 300 to secure it to the lower blanket, the glued pipeline is laid along a predetermined path and compacted onto the lower blanket using the pressing wheel 213, ensuring that the pipeline 300 is firmly bonded to the lower blanket. This adhesive bonding secures the pipeline 300 to the lower blanket, preventing separation between the lower blanket and the pipeline 300 and preventing deformation of the lower blanket.

[0063] After the pipeline 300 is laid, coated and compacted, the upper blanket surface is pressed onto the lower blanket surface to form a finished heating blanket.

[0064] Example 3

[0065] The pipeline laying process includes the following steps: S1. While using a wiring mechanism to lay the pipeline 300 to be laid on the lower blanket according to a set route, a dipping mechanism is used to dip glue on the outside of the pipeline to fix it on the lower blanket. In this embodiment 1, the wiring mechanism adopts the wiring mechanism 200, and the dipping mechanism is implemented by a dipping machine provided on the wiring mechanism 200.

[0066] S2: While the exterior of the pipeline 300 is being dipped in glue to secure it to the lower blanket, the press roller 213 is used to lay the dipped pipeline along a predetermined path and compact it onto the lower blanket, firmly adhering the pipeline 300 to the blanket. This adhesive bonding secures the pipeline 300 to the blanket, preventing separation between the lower blanket and the pipeline 300 and preventing deformation of the blanket.

[0067] After the pipeline 300 is laid, impregnated and compacted, the upper blanket surface is pressed onto the lower blanket surface to form a finished heating blanket.
