Description

Technical Field

[0001] The present application relates to the field of wire drawing rollers, and in particular to a wire drawing roller with uniform heating and a wire drawing machine using the wire drawing roller. Background Art

[0002] Wire drawing machine, also called wire drawing machine, is a widely used mechanical equipment in industrial applications. It is widely used in machinery manufacturing, hardware processing, petrochemical, plastic, bamboo and wood products, wire and cable and other industries. According to its use, wire drawing machine can be divided into metal wire drawing machine (used for pre-processing of metal products such as standard parts), plastic wire drawing machine (used in the plastic products industry to produce various hollow, solid round wires or flat wires for deep processing with polyester, nylon, polyethylene, polypropylene, polyester chips, etc. as raw materials), bamboo and wood wire drawing machine (used in the bamboo and wood products industry to make chopsticks, toothpicks, barbecue sticks, etc., and pull out bamboo and wood wires for reprocessing) and so on. Plastic wire drawing machine uses polypropylene and high-density ethylene as raw materials, and forms flat wires through heating, extrusion, wire splitting and stretching, which are wound up and woven by circular looms.

[0003] A Chinese patent with announcement number CN202072822U discloses a hot roller for a plastic extrusion lawn monofilament drawing unit, including a hot roller shaft, a double-layer sleeve structure is arranged outside the hot roller shaft, and a spiral guide vane is arranged between the double-layer sleeve structure. The double-layer sleeve structure includes an outer cylinder and an inner cylinder, and a spiral guide vane is arranged between the outer cylinder and the inner cylinder.

[0004] The inventors found that the heat roller in the above scheme adopts a spiral flow channel, which makes the contact between the heat transfer oil and the heat transfer roller more complete, thereby improving the heat exchange effect. However, during the flow of the heat transfer oil, the heat will gradually be lost, resulting in a temperature difference at different points along the axis of the heat roller, resulting in uneven shrinkage of the drawn silk thread. Summary of the invention

[0005] In order to improve the problem of unequal temperatures at various locations of the hot roller along its own axis, the present application provides a wire drawing roller with uniform heating and a wire drawing machine using the wire drawing roller.

[0006] In the first aspect, the present application provides a uniformly heated wire drawing roller, which adopts the following technical solution:

[0007] A wire drawing roller with uniform heating comprises a roller, wherein a plurality of heating modules are sequentially arranged inside the roller along its own axial direction, a heating area is formed between each heating module and the inner wall of the roller, and each heating module is provided with a temperature measuring component for monitoring the temperature of the heating area and controlling the opening and closing of the heating module.

[0008] By adopting the above technical scheme, multiple heating modules form multiple heating areas in the roller, and each heating area is monitored by a group of temperature measuring components. When the temperature of the heating area is too high, the temperature measuring component controls the heating module to turn off; when the temperature of the heating area is too low, the temperature measuring component controls the heating module to turn on, so that the temperature of each heating area is always almost equal, thereby improving the uniformity of the overall heating of the roller, and thereby making the wire drawn by the wire drawing machine shrink evenly; at the same time, the heating module is used for heating. Compared with introducing a heat source, there is no need to accidentally set up a heating device in the wire drawing machine, which reduces the cost of use.

[0009] Optionally, it also includes a roller shaft, the roller is coaxial with the roller shaft, the roller shaft is located inside the roller, and the roller shaft is rotatably connected to the roller, and the heating module and the temperature measuring component are both arranged on the roller shaft.

[0010] By adopting the above technical solution, the roller is fixed. Compared with installing on a roller, it is more convenient to install the heating module and the temperature measuring component on the roller, which can improve the assembly efficiency.

[0011] Optionally, a heat insulation plate is provided on the inner wall of the roller, a plurality of the heat insulation plates are provided along the axial direction of the roller, and the heat insulation plates are provided between adjacent heating areas.

[0012] By adopting the above technical solution, the insulation board can easily separate adjacent heating areas, so that the heat flow in the heating area is less, thereby making the temperature monitoring more accurate. At the same time, the insulation board can also improve the strength of the roller and reduce the possibility of deformation of the roller during the long wire drawing process.

[0013] Optionally, the heating module includes a mounting frame and a heating tube, the mounting frame includes a mounting tube and a mounting ring, the mounting tube is coaxial with the roller shaft and is sleeved on the roller shaft, the mounting ring is relatively arranged at two ends of the mounting tube along its axial direction, the heating tube is arranged between the two mounting rings, and multiple heating tubes are arranged along the circumference of the roller.

[0014] By adopting the above technical solution, the combination of the mounting tube and the mounting ring facilitates the installation and protection of the heating tube, thereby improving the heating efficiency.

[0015] Optionally, the temperature measuring component includes an infrared sensor, which is fixedly connected to the side wall of the roller shaft, and the infrared sensor is arranged between adjacent heating tubes. The mounting tube is provided with an avoidance hole for the infrared sensor to pass through, and the sensing end of the infrared sensor is arranged toward the heating area.

[0016] By adopting the above technical solution, the infrared sensor is installed on the side wall of the roller shaft, which is easier to install and disassemble than installing it inside the roller shaft, thereby improving the efficiency of assembly and maintenance of operators.

[0017] Optionally, heat dissipation holes are provided at both ends of the roller along its axial direction.

[0018] By adopting the above technical solution, the heat dissipation holes are beneficial to the heat dissipation of the roller, so that the roller heating temperature can be quickly reduced to the set value when it is too high.

[0019] In a second aspect, the present application also provides a wire drawing machine, which adopts the following technical solution:

[0020] A wire drawing machine comprises a frame, wherein the roller is horizontally fixedly connected to the frame, and the frame is provided with a driving device for driving the roller to rotate.

[0021] By adopting the above technical scheme, the roller shaft and roller in the above scheme are used. During the working process, the roller shaft is fixed, and the roller rotates. The roller shaft plays a good supporting role on the roller, reducing the vibration of the roller during rotation; on the other hand, by adopting a self-heating heating module and a corresponding temperature measuring component, it is possible to achieve independent temperature measurement and temperature control in multiple areas, improve the accuracy of temperature control, and then improve the overall thermal uniformity of the roller, so that the wire drawn by the wire drawing machine shrinks evenly.

[0022] Optionally, a support frame is provided at one end of the roller away from the frame, a connecting rod is fixedly connected to the support frame, and one end of the connecting rod away from the support frame is fixedly connected to a pin.

[0023] By adopting the above technical solution, the support rod and the connecting frame are convenient for supporting the roller shaft, and cooperate with the frame to improve the stability of the roller shaft fixation, thereby reducing the possibility of jumping when the roller rotates.

[0024] Optionally, a blowing assembly is rotatably connected to the connecting rod, the blowing assembly is fixedly connected to the roller, and the airflow generated by the blowing assembly being driven by the roller flows toward the roller shaft.

[0025] By adopting the above technical solution, when the roller rotates, it drives the blowing assembly to rotate, generating a strong airflow flowing toward the roller shaft to cool the roller, thereby reducing the possibility that the roller temperature is difficult to drop even if the heating module is not working due to the difficulty in heat dissipation of the roller, thereby facilitating the control of the roller temperature and improving the overall thermal uniformity of the roller; at the same time, the roller drives the blowing assembly to rotate, and no other driving source is required, thereby reducing energy consumption.

[0026] Optionally, an end of the roller shaft facing the support frame is provided with an air guide sleeve for guiding the airflow generated by the blowing assembly into the roller shaft, and an end of the pin shaft facing the support frame is provided with a ventilation hole for the airflow to pass through.

[0027] By adopting the above technical solution, the inside of the roller is an area with less heat flow and difficult to dissipate heat. The air guide sleeve guides the airflow generated by the blowing assembly into the inside of the roller, which can accelerate the heat flow inside the roller and facilitate the temperature control of the roller.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The setting of the heating module and the temperature measuring component can improve the uniformity of the overall heating of the roller, so that the wire drawn by the wire drawing machine can shrink evenly;

[0030] 2. The setting of the support frame and the connecting rod can improve the stability of the roller shaft and reduce the vibration of the roller;

[0031] 3. Through the setting of the blowing assembly and the air guide sleeve, the rotation of the roller accelerates the heat dissipation speed inside the roller shaft, reduces energy waste, and facilitates the temperature control of the roller. At the same time, the structure is compact, no additional fan is required, and the production cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-12 This application is described in further detail.

[0046] In a first aspect, an embodiment of the present application discloses a wire drawing roller with uniform heating.

[0047] Reference Figure 1 and Figure 2A wire drawing roller with uniform heating includes a roller shaft 1 and a roller 2, wherein the roller shaft 1 is fixed, the roller 2 is coaxially sleeved on the roller shaft 1, and the roller 2 is rotatably connected to the roller shaft 1 through a rotating assembly 21. A plurality of heating modules 3 are arranged on the roller shaft 1 along its axial direction, and the heating modules 3 may be three or four. A heating area 22 is formed between each heating module 3 and the roller 2, and a temperature measuring assembly 4 is also arranged in each heating module 3, which is used to monitor the temperature of the corresponding heating area 22 and control the opening and closing of the heating module 3. The heating module 3 generates heat, which is dissipated to the heating area 22 to heat the roller 2, and the roller 2 then heats the wire passing through the roller 2; at this time, the temperature measuring assembly 4 monitors the temperature of the heating area 22, and if the temperature of the heating area 22 is too high, the heating module 3 is controlled to be turned off, and if the temperature of the heating area 22 is too low, the heating module 3 is controlled to be turned on, so that the temperature of the heating area 22 is always kept at a fixed value, thereby making the wire passing through the roller 2 shrink uniformly.

[0048] Reference Figure 1 , heat dissipation holes 24 are provided on the end faces of both ends of the roller 2 along its axial direction, and there are multiple heat dissipation holes 24 arranged in a circumferential array along the roller 2, which are convenient for heat dissipation, so that when the temperature of the heating area 22 of the roller 2 is too high, it can be quickly reduced to the set value. A support block 11 is also provided in the roller shaft 1, and the support block 11 is relatively arranged at both ends of the roller shaft 1 along the axial direction of the roller shaft 1. A support rod 111 is welded to the circumference of the support block 11, and a plurality of support rods 111 are arranged in an axial array along the roller shaft 1. One end of the support rod 111 away from the support block 11 is welded to the inner wall of the roller shaft 1. The support block 11 cooperates with the support rod 111 to support the roller shaft 1, increase the strength of the roller shaft 1, and reduce the possibility that the roller 2 is difficult to rotate or jumps too much due to the deformation of the roller shaft 1.

[0049] Reference Figure 3 and Figure 4The rotating assembly 21 includes a first pulley 211 and a second flange 212. The first pulley 211 is sleeved on the roller shaft 1. A first rolling groove 2121 is provided at one end of the first pulley 211 away from the roller 2. A first bearing 2124 is interference fit in the first rolling groove 2121. A first shoulder 2122 is also provided on the roller shaft 1. The inner ring of the first bearing 2124 abuts against the first shoulder 2122 at one end away from the roller 2. The end of the first pulley 211 facing the roller 2 is fixedly connected to the second flange 212 by bolts, and the end of the second flange 212 away from the first pulley 211 is threadedly connected to the roller 2 by bolts. A first bearing section 2123 is integrally formed at one end of the first shoulder 2122 facing the roller 2, which is used for interference fit with the inner ring of the first bearing 2124. The diameter of the first bearing section 2123 is slightly larger than the overlapped portion of the roller shaft 1 and the roller 2, so that the first bearing 2124 can pass through the overlapped portion of the roller shaft 1 and the roller 2 when being installed. Since the processing requirements for the first bearing segment 2123 are relatively high, the length of the first bearing segment 2123 is set to be relatively short, and may be slightly larger or slightly smaller than the width of the first bearing 2124 .

[0050] Reference Figure 3 and Figure 5 The rotating assembly 21 further includes a third flange 212, and the end of the roller 2 away from the first shoulder 2122 is fixedly connected to the third flange 212 by bolts. A second rolling groove 2131 is provided at the end of the third flange 212 away from the roller 2, and a second bearing 2136 is interference-fitted in the second rolling groove 2131. A second shoulder 2132 is also provided on the roller shaft 1, and the second shoulder 2132 is arranged at the end of the roller 2 away from the first shoulder 2122, and the inner ring of the second bearing 2136 is in contact with the second shoulder 2132 at the end facing the roller 2. A second bearing section 2133 is integrally formed at the end of the second shoulder 2132 away from the roller 2. The diameter of the second bearing section 2133 is slightly smaller than the diameter of the portion where the roller shaft 1 and the roller 2 overlap, and is used for interference fit with the inner ring of the second bearing 2136. A retaining ring groove 2134 is opened on the side wall of the second bearing section 2133 along its circumference, and an elastic retaining ring 2135 is clamped in the retaining ring groove 2134. The elastic retaining ring 2135 abuts against the end of the inner ring of the second bearing 2136 away from the roller 2.

[0051] During installation, first fit the first bearing 2124 into the first rolling groove 2121, then slip the second flange 212 onto the roller shaft 1, and make the inner ring of the first bearing 2124 have an interference fit with the first bearing section 2123. Next, slip the roller 2 onto the roller shaft 1, and fixedly connect the second flange 212 and the roller 2 with bolts. Subsequently, install the second bearing 2136 into the second rolling groove 2131, then slip the third flange 212 onto the roller shaft 1, make the inner ring of the second bearing 2136 have an interference fit with the second bearing section 2133, then snap the elastic retaining ring 2135 into the retaining ring groove 2134, and finally fixedly connect the third flange 212 and the roller 2 with bolts to complete the connection between the roller 2 and the roller shaft 1, facilitating relative rotation between the roller 2 and the roller shaft 1.

[0052] Refer to Figure 2 and Figure 6 As shown in FIGS. Figure 2 and Figure 6 , the heating module 3 includes a mounting frame 31 and heating tubes 32. The mounting frame 31 includes an integrally formed mounting cylinder 311 and mounting rings 312. The mounting cylinder 311 is coaxial with the roller shaft 1 and is sleeved on the roller shaft 1. The mounting rings 312 are oppositely arranged at both ends of the mounting cylinder 311 along its axial direction. The heating tubes 32 are fixedly connected between the two mounting rings 312 and are arranged in a circumferential array along the roller 2. The heating tubes 32 can be quartz heating tubes 32 or electric heating tubes 32. To facilitate fixing the mounting cylinder 311 and the mounting rings 312 on the roller shaft 1, the mounting cylinder 311 and the mounting rings 312 can adopt a split structure. The two parts split along the axis of the mounting ring 312 are fixed with bolts, and the two split parts are clamped with each other and then fixed on the roller shaft 1.

[0053] Refer to Figure 6 and Figure 7 As shown in FIGS. Figure 6 and Figure 7 , the temperature measuring component 4 includes an infrared sensor 41 and a mounting sleeve 42. The sensing end of the infrared sensor 41 faces the heating area 22, facilitating monitoring the temperature of the heating area 22. The mounting sleeve 42 is welded to the side wall of the roller shaft 1. One end of the mounting sleeve 42 along its own axial direction penetrates into the roller shaft 1. A connecting plate 43 is provided in the inner hole of the roller shaft 1. The connecting plate 43 is in a U shape and includes a first cross plate 431, a vertical plate 433, and a second cross plate 432 that are integrally formed in sequence. The first cross plate 431 is parallel to the second cross plate 432. The first cross plate 431 is penetrated by the end of the mounting sleeve 42 located inside the roller shaft 1. A locking sleeve 44 is threadedly connected to the end of the mounting sleeve 42 that penetrates the first cross plate 431. The end of the locking sleeve 44 facing the first cross plate 431 abuts against the first cross plate 431. The locking sleeve 44 is located between the first cross plate 431 and the second cross plate 432. The infrared sensor 41 is threadedly connected to the second cross plate 432, facilitating adjusting the distance between the infrared sensor 41 and the heating area 22 to improve the detection accuracy. During detection, the light of the infrared sensor 41 passes through the mounting sleeve 42 and shines on the heating area 22.

[0054] Reference Figure 6 and Figure 7 The installation tube 311 is provided with an escape hole for escaping the installation sleeve, so as to facilitate the installation of the installation sleeve. The infrared sensor 41 is electrically connected to the controller of the heating tube 32. When the infrared sensor 41 detects that the temperature of the heating area 22 is too high, the infrared sensor 41 transmits an electrical signal to the controller of the heating tube 32 to control the heating tube 32 to stop heating; when the infrared sensor 41 detects that the temperature of the heating area 22 is too low, the infrared sensor 41 transmits an electrical signal to the controller of the heating tube 32 to control the heating tube 32 to heat, thereby keeping the temperature of the heating area 22 relatively stable.

[0055] Reference Figure 2 , a heat insulation board 23 is welded on the inner wall of the roller 2, and a plurality of heat insulation boards 23 are arranged along the axial direction of the roller 2, and the heat insulation boards 23 are ring-shaped along the axial direction of the roller 2. The heat insulation boards 23 are arranged between adjacent heating areas 22 to reduce the possibility of temperature instability in the heating area 22 due to heat transfer between adjacent heating areas 22. The inner diameter of the heat insulation board 23 is larger than the outer diameter of the mounting ring 312 to reduce the possibility of interference between the heat insulation board 23 and the mounting ring 312 when the roller 2 is sleeved on the roller shaft 1. The heat insulation board 23 can also extend between adjacent mounting rings 312, but when this method is used, the roller 2 and the heat insulation board 23 need to adopt a split structure to facilitate the installation of the roller 2.

[0056] The implementation process of a wire drawing roller with uniform heating in the embodiment of the present application is as follows: when the wire drawing roller is working, the roller 2 rotates relative to the roller shaft 1, driving the wire to be transmitted, and at the same time the heating tube 32 generates heat, and the heat fills the heating area 22. At this time, the infrared sensor 41 monitors the temperature of the heating area 22. When the infrared sensor 41 detects that the temperature of the heating area 22 is too high, the infrared sensor 41 transmits an electrical signal to the controller of the heating tube 32 to control the heating tube 32 to stop heating; when the infrared sensor 41 detects that the temperature of the heating area 22 is too low, the infrared sensor 41 transmits an electrical signal to the controller of the heating tube 32 to control the heating tube 32 to heat, thereby keeping the temperature of the heating area 22 relatively stable.

The first flange 12 abuts against the end of the fixing ring 522 away from the frame 5. The first flange 12 and the fixing ring 522 are fixedly connected by bolts. The cooperation of the bushing 521, the fixing ring 522 and the first flange 12 makes the fixation between the roller shaft 1 and the frame 5 more stable.

[0064] Reference Fig.11 and Fig.12A first fixing hole is formed at one end of the first fixing rod 547 toward the fixing plate 534, a second fixing hole is formed at one end of the second fixing rod 548 toward the fixing plate 534, a first connecting hole 5347 and a second connecting hole 5348 are formed on the fixing plate 534, the first connecting hole 5347 is coaxial with the first fixing hole and has the same diameter, the second connecting hole 5348 is coaxial with the second fixing hole and has the same tangent diameter, and the insertion block 5344 is compatible with both the first fixing hole and the second fixing hole. When it is necessary to connect the fixing plate 534 with the first fixing rod 547 or the second fixing rod 548, pinch the limit block 5345, pull the insertion rod 5343 in the direction of the fixing plate 534 away from the roller 2, and then rotate the rotating shaft 5341 to insert the insertion block 5344 into the first connecting hole 5347 or the second connecting hole 5348 until the insertion block 5344 abuts against the bottom of the first fixing hole or the second fixing hole. At this time, the first fixing rod 547 or the second fixing rod 548 rotates to drive the fixing plate 534 to rotate, and then drives the fan blade 5322 to rotate to generate airflow. The compression spring 5346 can reduce the possibility of the insertion block 5344 being separated from the first fixing hole or the second fixing hole. The cooperation between the insertion block 5344 and the first fixing hole or the second fixing hole can switch the different rotation speeds of the fan blades 5322. When the insertion block 5344 is inserted into the first fixing hole, the rotation of the roller 2 drives the fan blades 5322 to rotate; when the insertion block 5344 is inserted into the second fixing hole, the planetary gear 543 revolves to drive the fan blades 5322 to rotate, thereby generating different rotation speeds.

Ventilation holes are formed between adjacent support rods 111 to facilitate airflow. The airflow generated by the rotation of the fan blade 5322 flows toward the roller 2, flows into the interior of the roller 1 along the air guide sleeve 533, and cools the interior of the roller 1.

[0066] The implementation process of a wire drawing machine in the embodiment of the present application is as follows: when the wire drawing machine is working, the driving motor 511 drives the second pulley 512 to rotate, and the second pulley 512 drives the first pulley 211 to rotate through the conveyor belt 513, and then drives the roller 2 to rotate to transmit the wire. The rotation of the roller 2 drives the planetary gear and the second fixed rod to rotate, and then drives the fixed plate to rotate through the first fixed rod or the second fixed rod, and then drives the fan blade to rotate, generating airflow to flow into the air guide sleeve 533, and flows into the roller shaft 1 along the air guide sleeve 533 to cool the inside of the roller shaft 1.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
