Description

Technical Field

[0001] The utility model relates to the technical field of heating tape processing, in particular to a length-metering type self-controlling temperature heating tape production reel. Background Art

[0002] Heating cables are electric heating devices used for heating. They typically consist of one or more heating wires or films, wrapped in insulation and a protective layer. They can be used in a variety of applications, such as pipe insulation, frost protection, heating, snow melting, and ice prevention.

[0003] Currently, heating cables are primarily manufactured by rolling them into a reel to facilitate transportation. Measuring the reel's length involves measuring the diameter of the reel with a tape measure, which provides a rough estimate of the total length. This process is cumbersome and can result in significant errors, impacting processing efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a reel for producing a length-metering self-regulating temperature heating tape. When the reel reels the self-regulating temperature heating tape through the reeling mechanism, the self-regulating temperature heating tape can drive the trigger wheel of the metering mechanism to rotate under the action of friction. At this time, the metering wheel rotates synchronously, thereby triggering the metering striker to hit the counter. Finally, the count value of the counter is converted into the length value of the self-regulating temperature heating tape through the control unit. The utility model is very convenient in application and effectively improves the processing efficiency of the self-regulating temperature heating tape.

[0005] In order to solve the above technical problems, the technical solution of the utility model is achieved as follows:

[0006] A length-metering, self-regulating, temperature-heating tape reel comprises a base, with a reeling mechanism and a metering mechanism mounted on both ends of the base, and a control unit mounted in the middle of the base for simultaneously controlling the operation of the reeling mechanism and the metering mechanism.

[0007] The metering mechanism includes a base, a trigger wheel is mounted on one side of the base, a metering wheel is concentrically connected to the bottom of the trigger wheel, the trigger wheel and the metering wheel are rotatably connected to an L-shaped push seat on a common rotating shaft, and the L-shaped push seat is slidably connected to a guide rod fixed to the base, and the guide rod is sleeved with a spring for pushing the L-shaped push seat toward the base.

[0008] A metering striker is also installed on the side of the base away from the trigger wheel. The metering striker is slidably connected to a second guide rod fixed on the base. The second guide rod is sleeved with a second spring that pushes the metering striker to move toward the base. Under the action of the second spring, the metering striker can pass through the base plate and contact the surface of the metering wheel.

[0009] A metering striker is fixed to the side of the metering striker away from the striker, and a counter electrically connected to the control unit is installed next to the metering striker. A protrusion is fixed on the metering wheel; when the protrusion contacts the metering striker, the needle of the metering striker can contact the switch of the counter; when the protrusion does not contact the metering striker, the needle of the metering striker cannot contact the switch of the counter.

[0010] The control unit includes a central processing unit and a display screen. The central processing unit stores a calculation program for converting the count value of the counter into the length value of the self-controlling temperature heating belt.

[0011] By adopting the above scheme, while the retractor rewinds the self-regulating temperature heating tape through the rewinding mechanism, the self-regulating temperature heating tape can drive the trigger wheel of the metering mechanism to rotate under the action of friction. At this time, the metering wheel rotates synchronously, thereby triggering the metering striker to hit the counter. Finally, the count value of the counter is converted into the length value of the self-regulating temperature heating tape through the control unit. It is very convenient in application and effectively improves the processing efficiency of the self-regulating temperature heating tape.

[0012] As a preferred embodiment of a length-metering self-regulating temperature heating tape retractor, the central processing unit's calculation program adopts "P=nπd"; where P is the length of the self-regulating temperature heating tape, n is the count value of the counter, and d is the diameter of the trigger wheel.

[0013] Using the above solution, in order to realize the conversion of the length value of the self-regulating temperature heating tape, the calculation program of the central processing unit uses "P=nπd" for conversion. By presetting the length value of the self-regulating temperature heating tape to be processed, when the count value of the corresponding counter is reached, the control unit will control the operation of the winding mechanism to stop.

[0014] As a preferred embodiment of a length-metering self-regulating temperature heating tape production retractor, the outer surface of the trigger wheel is provided with a plurality of anti-slip grooves distributed in a circumferential array.

[0015] By adopting the above solution, in order to increase the friction between the trigger wheel and the self-controlling temperature heating belt, anti-slip grooves are provided on the surface of the trigger wheel to increase the friction, thereby ensuring the accuracy of the measurement.

[0016] As a preferred embodiment of a length-metering self-regulating temperature heating tape production retractor, a bracket is fixed on the side of the base facing the trigger wheel, and the bracket is located at the height of the trigger wheel.

[0017] By adopting the above solution, in order to facilitate the placement of the self-regulating temperature heating tape, the self-regulating temperature heating tape is placed on the bracket. At this time, the trigger wheel is pushed by the elasticity of spring 1, and the trigger wheel will always be in contact with the self-regulating temperature heating tape. When the self-regulating temperature heating tape is retracted, the trigger wheel will rotate, thereby facilitating real-time measurement of the length of the self-regulating temperature heating tape.

[0018] As a preferred embodiment of a reel for length-metering self-controlling temperature heating tape production, the reeling mechanism includes a rotating seat, which is rotatably connected to an annular slide rail fixed on the machine base, and a motor for driving the rotating seat to rotate is fixed below the machine base, and the motor is electrically connected to the control unit; a vertically arranged reel is fixed directly above the rotating seat, and a vertically arranged reeling groove is provided in the middle of the reeling drum; a reeling tray mounted on the reeling drum is also placed above the rotating seat.

[0019] Using the above solution, in order to realize the reeling of the self-regulating temperature heating tape, one end of the self-regulating temperature heating tape is inserted into the reeling groove, and then the rotating seat is driven by the motor to rotate, and then the self-regulating temperature heating tape will be continuously reeled around the reeling drum, and the reeling drum can be rolled into a reel for easy transportation.

[0020] As a preferred embodiment of a reel for length-metering self-controlling temperature heating tape production, two mutually symmetrical limit blocks are fixed on the outside of the reeling drum, and two mutually symmetrical limit grooves are opened on the inside of the reeling tray, which can be limitedly assembled on the limit blocks.

[0021] By adopting the above solution, in order to facilitate the removal of the self-regulating temperature heating tape after winding, a winding tray is placed on the upper limit of the rotating seat. At this time, the self-regulating temperature heating tape will be wound on the winding tray. The winding tray is removed upward along the winding drum, and the wound self-regulating temperature heating tape can be removed together.

[0022] As a preferred embodiment of a length-metering self-regulating temperature heating tape production reel, the outer surface of the reel drum is provided with a plurality of anti-slip grooves distributed in a circumferential array.

[0023] By adopting the above solution, in order to improve the contact friction between the reel and the self-regulating temperature heating belt, anti-slip grooves are provided on the surface of the reel to improve the friction, thereby ensuring reliability during reeling.

[0024] As a preferred embodiment of a length-metering self-regulating temperature heating tape production reel, when the length direction of the reeling groove is perpendicular to the length direction of the bracket, this is the initial state of the reeling drum before reeling.

[0025] By adopting the above scheme, in order to ensure that the self-regulating temperature heating tape can be smoothly wound up following the winding drum, the length direction of the winding groove and the length direction of the bracket are arranged perpendicular to each other. Once the self-regulating temperature heating tape is bent and extended into the winding groove, the self-regulating temperature heating tape can be smoothly wound up following the winding drum.

[0026] After adopting the above technical solution, the beneficial effects of the utility model are:

[0027] 1. While the retractor rewinds the self-regulating temperature heating tape through the retracting mechanism, the self-regulating temperature heating tape can drive the trigger wheel of the metering mechanism to rotate under the action of friction. At this time, the metering wheel rotates synchronously, thereby triggering the metering striker to hit the counter. Finally, the count value of the counter is converted into the length value of the self-regulating temperature heating tape through the control unit. It is very convenient in application and effectively improves the processing efficiency of the self-regulating temperature heating tape.

[0028] 2. In order to realize the conversion of the length value of the self-regulating temperature heating tape, the calculation program of the central processing unit adopts "P=nπd" for conversion. By presetting the length value of the self-regulating temperature heating tape to be processed, when the count value of the corresponding counter is reached, the control unit will control the operation of the reeling mechanism to stop;

[0029] 3. To facilitate the placement of the self-regulating temperature heating tape, place the self-regulating temperature heating tape on the bracket. At this time, the trigger wheel will always be in contact with the self-regulating temperature heating tape under the elastic push of spring 1. When the self-regulating temperature heating tape is retracted, the trigger wheel will rotate, thereby facilitating real-time measurement of the length of the self-regulating temperature heating tape.

[0030] 4. In order to realize the reeling of the self-regulating temperature heating tape, one end of the self-regulating temperature heating tape is inserted into the reeling groove, and then the motor drives the rotating seat to rotate, and then the self-regulating temperature heating tape will be continuously reeled around the reeling drum, and the reeling drum can be rolled into a reel for easy transportation;

[0031] 5. In order to facilitate the removal of the self-regulating temperature heating tape after winding, place the winding tray on the upper limit of the rotating seat. At this time, the self-regulating temperature heating tape will be wound on the winding tray. Remove the winding tray upward along the winding drum, and the wound self-regulating temperature heating tape can be removed together;

[0032] 6. In order to ensure that the self-regulating temperature heating tape can be smoothly wound up following the winding drum, the length direction of the winding groove and the length direction of the bracket are set perpendicular to each other. Once the self-regulating temperature heating tape is bent and extended into the winding groove, the self-regulating temperature heating tape can be smoothly wound up following the winding drum.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figures 1 to 5As shown, a length-metering self-regulating temperature heating tape retractor for manufacturing includes a base 1, with a retracting mechanism 2 and a metering mechanism 3 mounted on both ends of the base 1, and a control unit 4 for simultaneously controlling the operation of the retracting mechanism 2 and the metering mechanism 3 mounted in the middle of the base 1;

[0046] The metering mechanism 3 includes a base 301, with a trigger wheel 302 mounted on one side of the base 301. A metering wheel 303 is concentrically connected to the bottom of the trigger wheel 302. The trigger wheel 302 and the metering wheel 303 are rotatably connected to an L-shaped push seat 304 about a common rotating shaft. The L-shaped push seat 304 is slidably connected to a guide rod 305 fixed to the base 301. The guide rod 305 is equipped with a spring 306 that pushes the L-shaped push seat 304 toward the base 301.

[0047] A metering ram 307 is mounted on the side of the base 301 away from the trigger wheel 302. The metering ram 307 is slidably connected to a second guide rod 308 fixed to the base 301. The second guide rod 308 is sleeved with a second spring 309 that pushes the metering ram 307 toward the base 301. Under the action of the second spring 309, the metering ram 307 can pass through the base plate and contact the surface of the metering wheel 303.

[0048] A metering striker 310 is fixed to the side of the metering striker 307 away from the striker. A counter 311 electrically connected to the control unit 4 is mounted next to the metering striker 310. A protrusion 312 is fixed to the metering wheel 303. When the protrusion 312 contacts the metering striker 307, the needle of the metering striker 310 can contact the switch of the counter 311. When the protrusion 312 does not contact the metering striker 307, the needle of the metering striker 310 cannot contact the switch of the counter 311.

[0049] The control unit 4 includes a central processing unit and a display screen. The central processing unit stores a calculation program for converting the count value of the counter 311 into the length value of the self-regulating temperature heating belt 5.

[0050] While the retractor rewinds the self-regulating temperature heating tape 5 through the retracting mechanism 2, the self-regulating temperature heating tape 5 can drive the trigger wheel 302 of the metering mechanism 3 to rotate under the action of friction. At this time, the metering wheel 303 rotates synchronously, thereby triggering the metering striker 310 to hit the counter 311. Finally, the count value of the counter 311 is converted into the length value of the self-regulating temperature heating tape 5 through the control unit 4. It is very convenient in application and effectively improves the processing efficiency of the self-regulating temperature heating tape 5.

[0051] like Figures 4 and 5As shown, the CPU's calculation program uses "P = nπd"; where P is the length of the self-regulating heating tape 5, n is the count value of the counter 311, and d is the diameter of the trigger wheel 302. To convert the length of the self-regulating heating tape 5, the CPU's calculation program uses "P = nπd" for conversion. By presetting the length of the self-regulating heating tape 5 to be processed, when the corresponding count value of the counter 311 is reached, the control unit 4 controls the winding mechanism 2 to stop.

[0052] like Figures 4 and 5 As shown, the outer surface of the trigger wheel 302 is provided with a plurality of anti-skid grooves distributed in a circumferential array. In order to increase the friction between the trigger wheel 302 and the self-regulating temperature heating belt 5, the anti-skid grooves are provided on the surface of the trigger wheel 302 to increase the friction and thus ensure the accuracy of the measurement.

[0053] like Figure 4 As shown, a bracket 313 is fixed to the side of the base 301 facing the trigger wheel 302, and the bracket 313 is located at the height of the trigger wheel 302. To facilitate the placement of the self-regulating temperature heating tape 5, the self-regulating temperature heating tape 5 is placed on the bracket 313. At this time, the trigger wheel 302 is pushed by the elastic force of the spring 1 306, and the trigger wheel 302 is always in contact with the self-regulating temperature heating tape 5. When the self-regulating temperature heating tape 5 is retracted, the trigger wheel 302 rotates, thereby facilitating real-time measurement of the length of the self-regulating temperature heating tape 5.

[0054] like Figures 6 to 9 As shown, the reeling mechanism 2 includes a rotating base 201, which is rotatably connected to an annular slide rail 202 fixed to the machine base 1. A motor 203 is fixed below the machine base 1 to drive the rotating base 201 to rotate. The motor 203 is electrically connected to the control unit 4. A vertically arranged reel 204 is fixed directly above the rotating base 201, and a vertically arranged reel groove 205 is defined in the middle of the reel 204. A reeling tray 206 is also placed above the rotating base 201 and is mounted on the reel 204. To reel the self-regulating temperature heating tape 5, one end of the self-regulating temperature heating tape 5 is inserted into the reel groove 205. The motor 203 then drives the rotating base 201 to rotate. The self-regulating temperature heating tape 5 is then continuously reeled around the reel 204. The reel 204 can be rolled into a reel for easy transportation.

[0055] like Figures 8 and 9As shown, two symmetrical limit blocks 207 are fixed to the outside of the take-up drum 204, and two symmetrical limit grooves 208 are formed on the inside of the take-up tray 206. The limit grooves 208 can be fixedly assembled on the limit blocks 207. In order to facilitate the removal of the reeled self-regulating temperature heating tape 5, the take-up tray 206 is placed in the upper limit position on the rotating seat 201. At this time, the self-regulating temperature heating tape 5 will be reeled on the take-up tray 206. The take-up tray 206 is removed upward along the take-up drum 204, and the reeled self-regulating temperature heating tape 5 can be removed together.

[0056] like Figure 8 As shown, the outer surface of the reel 204 is provided with a plurality of anti-slip grooves distributed in a circumferential array. In order to improve the friction between the reel 204 and the self-regulating heating tape 5, the anti-slip grooves are provided on the surface of the reel 204 to increase the friction and ensure the reliability of the reel.

[0057] like Figure 1 As shown, when the length of the reeling groove 205 is perpendicular to the length of the bracket 313, this is the initial state of the reeling drum 204 before reeling. To ensure that the self-regulating temperature heating tape 5 can smoothly follow the reeling drum 204 during reeling, the length of the reeling groove 205 is perpendicular to the length of the bracket 313. Once the self-regulating temperature heating tape 5 is bent and inserted into the reeling groove 205, it can smoothly follow the reeling drum 204 to complete reeling.

[0058] The working principle of this utility model:

[0059] During use, the self-regulating temperature heating belt 5 is first introduced onto the bracket 313. At this time, the trigger wheel 302 is pushed by the elasticity of the spring 1 306, and the trigger wheel 302 will always be in contact with the self-regulating temperature heating belt 5; then the self-regulating temperature heating belt 5 is bent and extended into the reeling groove 205.

[0060] When winding, the motor 203 is started, and then the motor 203 drives the rotating seat 201 to rotate, and then the self-controlling temperature heating tape 5 will be continuously wound around the winding drum 204, and the winding drum 204 can be rolled into a disk for easy transportation; while winding, since the self-controlling temperature heating tape 5 is moving when winding, the trigger wheel 302 will rotate, and then the metering wheel 303 will rotate synchronously. Every time the metering wheel 303 rotates one circle, the protrusion 312 will hit the metering striker 307 once, and then the metering striker 310 will hit the switch of the counter 311 once, and the counter 311 will continue to count; the length value of the self-controlling temperature heating tape 5 to be processed is preset on the control unit 4, and the calculation program of the central processing unit uses "P=nπd" for conversion. When the corresponding count value of the counter 311 is reached, the control unit 4 will control the stopping of the winding mechanism 2, which is very convenient in application and effectively improves the processing efficiency of the self-controlling temperature heating tape 5.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
