Description

Technical Field

[0001] This application relates to the technical field of wire processing, and particularly to a drying device for wire processing. Background Art

[0002] In wire processing, wires are extruded by an extruder. The extruded wires need to be cooled by a water-cooled chassis, and then the cooled wires are transported to the next process for processing (directly wound into coils or cut into masterbatch).

[0003] The wire materials processed by the water-cooled chassis are directly transported to the next process. The outer surface of the wire is in a wet state, which makes it easy for foreign matters to adhere to the outer surface of the wire during transportation. Therefore, further improvement is needed. Utility Model Content

[0004] In order to reduce the possibility of foreign matters adhering to the outer surface of the cooled wire, this application provides a drying device for wire processing.

[0005] A drying device for wire processing provided by this application adopts the following technical solutions:

[0006] A drying device for wire processing includes a drying rack arranged on one side of the discharge end of the water-cooled chassis. The drying rack is provided with a hot air pipe for spraying hot air on the surface of the wire. The outer peripheral wall of the hot air pipe is provided with hot air outlet holes communicating with the inner cavity. There are multiple hot air outlet holes and they are distributed along the axial direction of the hot air pipe. The drying rack is provided with an air supply component for delivering hot air into the inner cavity of the hot air pipe.

[0007] By adopting the above technical solutions, the air supply component continuously delivers hot air into the inner cavity of the hot air pipe. The hot air in the hot air pipe is sprayed out through the hot air outlet holes, so as to spray hot air on the surface of the cooled wire, thereby drying the residual moisture on the wire surface and reducing the possibility of foreign matters adhering to the outer surface of the cooled wire.

[0008] Preferably, the air supply component includes a heating air box, an air supply pipe with one end connected to the heating air box and the other end connected to the hot air pipe, a heater built in the heating air box for heating the gas, and a hot air blower for blowing the hot air into the hot air pipe.

[0009] By adopting the above technical solutions, the hot air blower blows the hot air in the heating air box into the hot air pipe, and the hot air is sprayed out through the hot air outlet holes, so as to spray hot air on the surface of the cooled wire, thereby drying the residual moisture on the wire surface.

[0010] Preferably, the drying rack includes a pair of mounting plates spaced apart from each other. The hot air duct is located between the two mounting plates. An installation pipe fixedly passing through the mounting plates coaxially is fixed to the end face of the hot air duct. An inner pipe is coaxially rotatably connected to the inner cavity of the hot air duct. The outer peripheral wall of the inner pipe abuts against the inner peripheral wall of the hot air duct. Through holes for communicating with the outside of the hot air duct are formed through the pipe wall of the inner pipe. The through holes and the hot air outlet holes are arranged corresponding to each other. The mounting plate is provided with a driving member for driving the inner pipe to rotate about its own axis.

[0011] By adopting the above technical solution, the inner pipe is driven to rotate by the driving member, so as to adjust the overlapping amount of the through holes and the hot air outlet holes, that is, to adjust the pore size of the hot air outlet holes, thereby adjusting the air volume of the hot air outlet holes and achieving the effect of controlling the drying rate. When the through holes and the hot air outlet holes are in a completely overlapping state, the air volume of the hot air outlet holes is the largest. When the through holes and the hot air outlet holes are in a completely misaligned state, the hot air outlet holes are closed.

[0012] Preferably, the installation pipe communicates with the inner cavity of the hot air duct. One end of the inner pipe is closed, and the other end of the inner pipe is open. The two outer end faces of the inner pipe respectively abut against the inner end faces of the hot air duct. The driving member includes a driving rod coaxially fixedly connected to the closed end face of the inner pipe and coaxially rotatably passing through the installation pipe. The end of the driving rod is exposed outside the mounting plate.

[0013] By adopting the above technical solution, one end of the inner pipe is closed and the other end is open, which is convenient for the hot air conveyed by the air supply assembly to enter the inner cavity of the inner pipe from the open end of the inner pipe. When the inner pipe is driven to rotate, the inner pipe is synchronously driven to rotate by rotating the driving rod.

[0014] Preferably, the installation pipe / mounting plate is provided with a limiting member for restricting the rotation of the driving rod in a damping manner.

[0015] Preferably, a limiting plate is convexly fixed on the outer wall of the mounting plate. The limiting member includes a limiting set screw threadedly passing through the limiting plate. The end of the limiting set screw abuts against the outer peripheral wall of the driving rod.

[0016] By adopting the above technical solution, after the driving rod is rotated and adjusted, by tightening the limiting set screw, the end of the limiting set screw abuts against the outer peripheral wall of the driving rod, thereby restricting the rotation of the driving rod in a damping manner.

[0017] Preferably, the limiting member is an anti-slip rubber ring coaxially fixedly embedded in the inner wall of the installation pipe. The driving rod passes through the anti-slip rubber ring, and the inner peripheral wall of the anti-slip rubber ring abuts against the outer peripheral wall of the driving rod.

[0018] By adopting the above technical solution, a resistance-increasing rubber ring is added. The inner peripheral wall of the resistance-increasing rubber ring abuts against the outer peripheral wall of the driving rod, thereby increasing the rotational friction force between the installation pipe and the driving rod. When the driving rod needs to be rotated, the operator needs to apply a large torque to the rotating rod to make the driving rod rotate.

[0019] Preferably, the drying rack is provided with a wire guide roller. The wire guide roller is located between the hot air pipe and the discharging end of the water-cooled machine box. A guiding wire groove for the wire to be embedded and passed through is circumferentially formed on the outer peripheral wall of the wire guide roller. There are a plurality of guiding wire grooves and they are distributed along the axial direction of the wire guide roller.

[0020] By adopting the above technical solution, a wire guide roller is added. The guiding wire grooves on the wire guide roller limit the wire, so that multiple wires are neatly arranged.

[0021] Preferably, the drying rack is provided with an electrostatic eliminator for eliminating the static electricity of the dried wire.

[0022] Preferably, the electrostatic eliminator is an ion air bar.

[0023] By adopting the above technical solution, the ion air bar generates a large amount of airflows with positive and negative charges, which are blown out at high speed by compressed air to neutralize the charges carried on the wire, thereby eliminating the static electricity on the wire and further reducing the possibility of foreign matters adhering to the outer surface of the wire.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. The air supply component continuously conveys hot air into the inner cavity of the hot air pipe. The hot air in the hot air pipe is ejected through the hot air outlet holes, thereby spraying hot air on the surface of the wire after cooling, so as to dry the residual moisture on the surface of the wire and reduce the possibility of foreign matters adhering to the outer surface of the wire after cooling;

[0026] 2. The driving part drives the inner pipe to rotate, thereby adjusting the overlapping amount of the through hole and the hot air outlet hole, that is, adjusting the pore size of the hot air outlet hole, thereby adjusting the air volume of the hot air outlet hole, achieving the effect of controlling the drying rate. When the through hole and the hot air outlet hole are in a completely overlapping state, the air volume of the hot air outlet hole is the largest. When the through hole and the hot air outlet hole are in a completely misaligned state, the hot air outlet hole is closed;

[0027] 3. The ion air bar generates a large amount of airflows with positive and negative charges, which are blown out at high speed by compressed air to neutralize the charges carried on the wire, thereby eliminating the static electricity on the wire and further reducing the possibility of foreign matters adhering to the outer surface of the wire.

Detailed implementation manners

[0033] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings.

[0034] Embodiment 1:

[0035] This application embodiment discloses a drying device for wire processing. Referring to Figure 1 , it includes a drying rack arranged on one side of the discharging end of the water-cooled machine case. The drying rack includes a pair of mounting plates 1 distributed along the width direction of the water-cooled machine case. In this embodiment, the mounting plate 1 is fixedly connected to the discharging end of the water-cooled machine case.

[0036] Referring to Figure 2 , a hot air pipe 2 for spraying hot air on the surface of the wire is arranged between the two mounting plates 1. Specifically, the hot air pipe 2 is located below the wire. A plurality of hot air outlet holes 21 communicating with the inner cavity are formed in the outer peripheral wall of the hot air pipe 2, and the hot air outlet holes 21 are arranged along the axial direction of the hot air pipe 2. An end face of the hot air pipe 2 is coaxially fixedly provided with a mounting pipe 22 fixedly penetrating through the mounting plate 1, and the mounting pipe 22 communicates with the inner cavity of the hot air pipe 2. An inner pipe 3 is coaxially rotatably connected in the inner cavity of the hot air pipe 2. The outer peripheral wall of the inner pipe 3 abuts against the inner peripheral wall of the hot air pipe 2. A through hole 31 for communicating with the hot air pipe 2 is formed through the outer peripheral wall of the inner pipe 3, and the through hole 31 and the hot air outlet hole 21 are correspondingly arranged.

[0037] One end of the inner pipe 3 is closed, and the other end of the inner pipe 3 is open. The two outer end faces of the inner pipe 3 respectively abut against the inner end faces of the hot air pipe 2. The mounting plate 1 is provided with a driving member for driving the inner pipe 3 to rotate around its own axis. The driving member includes a driving rod 32 coaxially fixedly connected to the closed end face of the inner pipe 3 and coaxially rotatably penetrating through the mounting pipe 22. The end of the driving rod 32 is exposed outside the mounting plate 1. A knob 33 externally disposed on the mounting plate 1 is coaxially fixedly connected to the end of the driving rod 32.

[0038] The installation pipe 22 / installation plate 1 is provided with a limiting member 12 that limits the rotation of the driving rod 32 in a damping manner. In this embodiment, a limiting plate 11 is fixedly protruded from the outer wall of the installation plate 1. The limiting plate 11 is located above the driving rod 32. The limiting member 12 includes a limiting set screw threadedly passing through the limiting plate 11, and the end of the limiting set screw abuts against the outer peripheral wall of the driving rod 32.

[0039] Referring to Figure 1 , the drying rack is provided with an air supply assembly 4 that conveys hot air into the inner cavity of the hot air pipe 2. The air supply assembly 4 includes a heating air box 41, an air supply pipe 42 with one end connected to the heating air box 41, a heater built in the heating air box 41 for heating the gas, and a hot air blower 43 for blowing the hot air into the hot air pipe 2. The air supply pipe 42 communicates with the installation pipe 22 on one side close to the open end of the inner pipe 3. A wire guide roller 5 is fixedly connected between the two installation plates 1. The wire guide roller 5 is located between the hot air pipe 2 and the discharge end of the water-cooled machine box. A plurality of wire guiding grooves for the wire to be embedded and passed through are circumferentially formed on the outer peripheral wall of the wire guide roller 5, and the wire guiding grooves are arranged in the axial direction of the wire guide roller 5.

[0040] The implementation principle of a drying device for wire processing in an embodiment of the present application is as follows: The hot air blower 43 blows the hot air in the heating air box 41 into the hot air pipe 2. The hot air sequentially enters the inner pipe 3 through the air supply pipe 42 and the installation pipe 22, and then sprays out through the through holes 31 and the hot air outlet holes 21, so as to spray hot air on the surface of the wire after cooling, thereby drying the residual moisture on the surface of the wire.

[0041] When it is necessary to adjust the air output of the hot air pipe 2, unlock the limiting set screw, drive the driving rod 32 to rotate by rotating the knob 33, thereby driving the inner pipe 3 to rotate, so as to adjust the overlapping amount of the through holes 31 and the hot air outlet holes 21, that is, adjust the pore size of the hot air outlet holes 21, thereby adjusting the air output of the hot air outlet holes 21 and achieving the effect of controlling the drying rate. When the through holes 31 and the hot air outlet holes 21 are in a completely overlapping state, the air output of the hot air outlet holes 21 is the largest. When the through holes 31 and the hot air outlet holes 21 are in a completely misaligned state, the hot air outlet holes 21 are closed.

[0042] Embodiment 2:

[0043] The difference from Embodiment 1 is that, referring to Figure 3 , the limiting member 12 is an increased-resistance rubber ring coaxially and fixedly embedded in the inner wall of the installation pipe 22. The driving rod 32 passes through the increased-resistance rubber ring, and the inner peripheral wall of the increased-resistance rubber ring abuts against the outer peripheral wall of the driving rod 32, increasing the sealing performance between the installation pipe 22 and the driving rod 32 and at the same time increasing the rotational friction force between the installation pipe 22 and the driving rod 32. When it is necessary to rotate the driving rod 32, the operator needs to apply a relatively large torque to the rotating rod to make the driving rod 32 rotate.

[0044] Embodiment 3:

[0045] The difference from Embodiment 1 is that, with reference to Figure 4 , on one side of the mounting plate 1 away from the discharge end of the cooling chassis, a fixing plate 13 is convexly fixedly connected. The fixing plate 13 is fixedly connected with an electrostatic eliminator for eliminating the static electricity of the dried wire. The electrostatic eliminator is an ion air bar 6 located above the wire. The ion air bar 6 generates a large amount of airflows with positive and negative charges and is blown out at high speed by compressed air to neutralize the charges carried on the wire, thereby eliminating the static electricity on the wire and further reducing the possibility of foreign matters adhering to the outer surface of the wire.

[0046] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
