Description

Technical Field

[0001] This invention relates to the technical field of heating blanket manufacturing, and more specifically to a pipeline laying device for heating blankets. Background Technology

[0002] A heating blanket is used for warmth and consists of an upper blanket, a lower blanket, and tubing located between the upper and lower blankets. Heating blankets are divided into electric blankets and water-heated blankets. In electric blankets, the tubing is made of heating wires that release heat when energized; in water-heated blankets, the tubing is made of water pipes through which hot water flows to release heat. During the manufacturing process, the tubing is first laid on the lower blanket, and then the upper and lower blankets are combined, with the tubing sandwiched between the two layers during the bonding process.

[0003] In existing technology, the lower layer of carpet is typically laid first, then numerous hanging pins are passed upwards from the bottom of the lower layer. The tubing is routed around and hung on the hanging pins. After the tubing is in place, all the hanging pins descend, and then the upper layer of carpet is laid. The drawbacks of this method are that the hanging pins can easily deform the lower layer of carpet as they pass through; moreover, during the laying process, the tubing is only hung on the hanging pins, and it frequently detaches from the pins, requiring workers to make corrections, which is cumbersome and inefficient. Summary of the Invention

[0004] This invention provides a pipeline laying device for heating blankets to solve the technical problems of easy deformation of the lower layer of blanket and easy detachment of pipeline from the hanging pin in the prior art.

[0005] To solve the above problems, the heating blanket pipeline laying device provided by the present invention adopts the following technical solution: a heating blanket pipeline laying device, comprising:

[0006] The wiring mechanism includes a mounting base, in which a wiring head is rotatably mounted about an axis extending vertically. The wiring head has a through hole that allows the conduit to pass through. The bottom of the wiring head has a spray nozzle for spraying adhesive onto the conduit. The bottom of the wiring head also has a grooved pressure roller located below the spray nozzle. The conduit passes around the pressure roller and extends downward. The pressure roller is used to press the adhesive-sprayed conduit onto the lower layer of blanket. The mounting base also has a reversing drive component, which is connected to the wiring head and drives the wiring head and the pressure roller to rotate about the axis extending vertically to change direction.

[0007] A drive mechanism, connected to the mounting base, is used to drive the mounting base to move horizontally along a set route. The drive mechanism is also used to drive the mounting base downward to press the pipeline onto the lower blanket.

[0008] The beneficial effects are as follows: By applying adhesive to the outside of the pipeline before pressing it onto the lower blanket, the pipeline is fixed to the lower blanket, relying on the adhesive's own strength to ensure the connection between the pipeline and the lower blanket. Compared to the existing method of threading pins through the lower blanket and hanging the pipeline on the pins, the pipeline laying device of this invention does not damage or deform the lower blanket. Furthermore, the bonding method is more secure, preventing pipeline movement and eliminating the need for worker intervention, saving time and improving pipeline laying efficiency. In this invention, only adhesive needs to be applied to the pipeline; there is no need to apply adhesive to the entire lower blanket, and the amount of adhesive used is also less. The pipeline laying device of this invention mounts the adhesive spray head and pressure roller on the same wiring head, allowing the spray head and pressure roller to rotate synchronously and ensure that the spray head is always in front of the pressure roller's direction of travel, achieving the function of spraying adhesive first and then pressing the pipeline. Since the pipeline laying device of the present invention does not rely on hanging pins, the laying path of the pipeline can be changed arbitrarily as needed, and it can adapt to the switching of various sizes, making it more adaptable and versatile.

[0009] Furthermore, the outer circumferential surface of the wiring head is provided with an annular groove, and the wiring head is provided with a dispensing channel connecting the annular groove and the glue spray head. The mounting base is provided with a glue inlet channel communicating with the annular groove, allowing glue to enter. The annular groove, glue inlet channel, and glue dispensing channel ensure that the glue dispensing from the glue spray head will not be affected no matter how the wiring head rotates, while also ensuring that the external glue tube will not become tangled.

[0010] Furthermore, the mounting base is equipped with a pneumatic valve that communicates with the glue inlet channel.

[0011] Furthermore, two ear plates are fixedly installed at the bottom of the wiring head, and the pressure roller is rotatably installed between the two ear plates; the two ear plates are also provided with limiting blocks, and the limiting blocks are provided with limiting grooves for the pipeline to pass through. The limiting grooves have groove walls on both sides of the extension direction of the pressure roller axis, and the groove walls are used to block and limit the pipeline.

[0012] Furthermore, grooved guide wheels are rotatably mounted on both ear plates, with the guide wheels located above the pressure rollers, allowing the pipeline to pass around and guide the pipeline.

[0013] Furthermore, the wiring head includes a small-diameter portion that passes through the mounting base, and a large-diameter portion located below the mounting base, with the pressure roller and the glue spraying head both located on the large-diameter portion.

[0014] Furthermore, the reversing drive component includes a motor mounted on the mounting base, with pulleys on both the output shaft of the motor and the upper end of the wiring head. The reversing drive component also includes a synchronous belt that passes over the two pulleys, and the wiring head is driven to rotate and reverse by the rotation of the motor.

[0015] Furthermore, the drive mechanism includes a telescopic component connected to the mounting base, which drives the mounting base to rise and fall; the drive mechanism also includes a translational component that drives the telescopic component to move in the horizontal direction.

[0016] Furthermore, the telescopic component is mounted on the translational component in an adjustable manner along the vertical direction.

[0017] Furthermore, the translational component includes a slide that can move in the horizontal direction, a C-shaped seat is fixed on the slide, the telescopic component is slidably assembled on the C-shaped seat in the vertical direction, and the C-shaped seat is also provided with a lead screw for driving the telescopic component to rise and fall.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

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

[0028] Embodiment 1 of the heating blanket pipeline laying device provided by the present invention:

[0029] like Figures 1 to 5 As shown, the pipeline of the present invention can be either the heating wire 300 in an electric blanket or the water pipe in a water-heated blanket. This embodiment will be illustrated by laying the heating wire 300 in an electric blanket.

[0030] The heating blanket piping laying device (hereinafter referred to as the laying device) includes a wiring mechanism 200 and a drive mechanism 100. The function of the wiring mechanism 200 is to apply adhesive to the heating wire 300 and press the adhesive-coated heating wire 300 onto the lower blanket. The function of the drive mechanism 100 is to drive the wiring mechanism 200 and the heating wire 300 to move horizontally along a set route, and simultaneously drive the wiring mechanism 200 to rise and fall. When descending, the wiring mechanism 200 can press the heating wire 300 onto the lower blanket.

[0031] The drive mechanism 100 includes a translational component and a telescopic component. The translational component includes a frame with two parallel first guide rails 101 mounted on it. For ease 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 spaced apart in the left-to-right direction. The drive mechanism 100 also includes a second guide rail 102 extending in the left-to-right direction, mounted on the two first guide rails 101, and capable of sliding in the front-to-back direction. The drive mechanism also includes a slide block 103 slidably mounted on the second guide rail 102 in the left-to-right direction. The method of driving the second guide rail 102 and the slide block 103 to slide can employ common methods such as a lead screw and nut mechanism, which will not be elaborated further here.

[0032] A first C-shaped seat 104 is fixedly mounted on the slide 103. The opening of the first C-shaped seat 104 faces horizontally, and a lead screw 105 is rotatably mounted inside. A guide rod 106 is also fixedly mounted inside. 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 and drives the lead screw 105 to rotate.

[0033] The telescopic component includes a slider 107 sleeved around the lead screw 105 and guide rod 106. The lead screw 105 and slider 107 are threaded together, causing 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 an upwardly extending piston rod. In other embodiments, a hydraulic cylinder or an electric actuator can be used instead of a cylinder.

[0034] 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 seat 201, which includes a horizontal plate and a vertical plate fixedly connected together. 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 installed at the bottom of the horizontal plate. The reinforcing plate 215 is slidably assembled on the outside of the cylinder body in the vertical direction. Through the cooperation between the reinforcing plate 215 and the cylinder body, the stability of the mounting base 201 during lifting and lowering can be improved.

[0035] The mounting base also includes a fixing seat 207 fixedly installed on the side of the vertical plate opposite to the horizontal plate. The fixing seat 207 has a through-hole, and a wiring head 209 is rotatably installed in the through-hole. The wiring head 209 can rotate about an axis extending vertically. A reversing drive component for driving the rotation of the wiring head 209 is installed on the mounting base. Specifically, the wiring head 209 includes a small-diameter portion at the top and a large-diameter portion at the bottom. The small-diameter portion passes through the through-hole of the fixing seat 207, and the upper end of the small-diameter portion protrudes from the upper end of the fixing seat 207. The reversing drive component includes a second C-shaped seat 202 mounted on the horizontal plate, with the opening of the second C-shaped seat 202 facing the fixed seat 207; the reversing drive component includes a second servo motor 203 fixedly mounted on the top of the second C-shaped seat 202, the motor shaft of the second servo motor 203 passing through the second C-shaped seat 202, a first pulley 204 fixedly mounted on the motor shaft, and a second pulley 205 fixedly mounted on the upper end of the small diameter portion of the wiring head 209; 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.

[0036] A through hole 220 is provided at the center of the wiring head 209, and the heating wire 300 passes through the through hole 220 from top to bottom.

[0037] A pressure roller 213 is rotatably mounted on the lower end of the wiring head 209. The rotation axis of the pressure roller 213 extends horizontally, and the pressure roller 213 has a groove in the middle into which the heating wire 300 can be inserted. Specifically, ear plates 210 are mounted on both sides of the large-diameter portion of the wiring head 209, and the pressure roller 213 is rotatably mounted between the two ear plates 210. A guide roller 212 is also rotatably mounted between the two ear plates 210, located above the pressure roller 213, and also has a groove in the middle into which the heating wire 300 can be inserted. In actual use, bearings are mounted on the ear plates 210, and the central axes of the pressure roller 213 and the guide roller 212 pass through the bearings. Here, both the pressure roller 213 and the guide roller 212 are driven wheels without driving force. When the wiring mechanism 200 is driven by the drive mechanism 100 to move horizontally, if the pressure roller 213 presses on the lower blanket, the pressure roller 213 will rotate.

[0038] The heating wire 300 passes downward through the wiring head 209 and then passes sequentially around the guide roller 212 and the pressure roller 213. During its movement, the pressure roller 213 presses down onto the lower layer of blanket. To limit the heating wire 300 entering the pressure roller 213 along its axial direction, a limiting block 214 is fixedly installed between the two ear plates 210. The limiting block 214 has a vertically penetrating limiting groove 216 with two side walls. The heating wire 300 passes downward through the limiting groove 216, and the side walls block and limit the heating wire 300.

[0039] 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 heating wire 300, which is the side of the heating wire 300 used to press onto the lower blanket. 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, and the glue spray head 211 is generally arranged from top to bottom and inclined towards the heating wire 300, which can spray glue onto the heating wire 300. The glue spray head 211 is located above the pressure roller 213, so that the heating wire 300 is first sprayed with glue and then pressed onto the lower blanket by the pressure roller 213, and then bonded and fixed to the lower blanket.

[0040] An annular groove 217 is formed on the outer circumferential surface of the small-diameter portion of the wiring head 209. An adhesive dispensing channel 218, connecting the adhesive spray head 211 and the annular groove 217, is formed inside the wiring head 209. The adhesive dispensing channel 218 can be an inclined channel or formed by connecting multiple straight channels. An adhesive inlet channel 219, communicating with the annular groove 217, is formed on the mounting base 207. The adhesive inlet channel 219 extends horizontally, allowing adhesive to enter the annular groove 217 even when the wiring head 209 rotates relative to the mounting base 207.

[0041] A pneumatic valve 208 is installed on one side of the mounting base 207. The outlet of the pneumatic valve 208 is connected to the glue inlet channel 219, and the inlet of the pneumatic valve 208 is connected to the glue hose. The pneumatic valve 208 can be opened or closed by compressed gas, thereby controlling whether glue enters the glue inlet channel 219. In actual use, a pump is installed on the glue hose to pressurize the glue.

[0042] In use, the heating wire 300 passes through the through hole 220 of the wiring head 209 from top to bottom, passes around the guide roller 212 and the pressure roller 213 in sequence, and extends to the bottom of the pressure roller 213. The glue spraying head 211 sprays glue onto the heating wire 300. The pressure roller 213 is driven by the drive mechanism 100 to press the heating wire 300 onto the lower blanket. When it is necessary to change direction, the second servo motor 203 starts, driving the wiring head 209, glue spraying head 211, guide roller 212, and pressure roller 213 to change direction together. The pressure roller 213 holds the heating wire 300 in place for changing direction, realizing continuous wiring.

[0043] In other embodiments of the present invention, to achieve adjustable position of the telescopic component on the translational component in the vertical direction, the following method can be adopted: a vertically extending groove is formed on the slide block, a slider extending into and engaging with the groove is fixedly installed on the telescopic component, multiple bolt holes are formed at intervals in the vertical direction at the bottom of the groove, and a threaded hole is formed on one side of the slider. The slider can be fixed in the groove by bolts, and the height of the cylinder can be adjusted by using different bolt holes corresponding to the threaded holes.

[0044] In this embodiment, the purpose of using the translational and telescopic components is to drive the wiring mechanism to move up and down as well as to move it horizontally. To achieve this purpose, in other embodiments of the invention, the driving mechanism can be a robot with a robotic arm that grasps the mounting base of the wiring mechanism and drives the mounting base to move and move up and down.

[0045] In this embodiment, the reversing drive component includes two pulleys, a synchronous belt, and a motor. To drive the wiring head to rotate, in other embodiments of the invention, the reversing drive component may include two sprockets, a chain, and a motor.

[0046] In this embodiment, a guide wheel is arranged above the pressure roller, and the pipeline first enters the groove of the guide wheel, and then enters the groove of the pressure roller. In other embodiments of the present invention, the guide wheel can be omitted.

[0047] In this embodiment, an annular groove is provided on the outer circumferential surface of the wiring head, an adhesive dispensing channel is provided inside the wiring head, and an adhesive inlet channel is provided inside the mounting base. In other embodiments of the present invention, the adhesive spray head is fixedly installed at the bottom of the wiring head, and the adhesive spray head is directly connected to the adhesive tube, which supplies adhesive, meaning the adhesive no longer passes through the interior of the wiring head.

[0048] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0049] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
