Description

Technical Field

[0001] The present application relates to the technical field of cable manufacturing, and particularly to an adjustable dryer. Background Art

[0002] When manufacturing cables, the extrusion process is used to wrap the cable inner core with an epidermis. Since the epidermis formed by extrusion has a relatively high temperature, it is necessary to first use a water tank to warm the epidermis, and then use a dryer to dry the water adhered to the epidermis before subsequent processing such as printing characters on the cable and spark withstand voltage testing for integrity can be carried out.

[0003] Existing dryers generally include an installation housing and a base for supporting the installation housing. A drying channel is provided on the installation housing, and the cable to be dried can directly pass through the drying channel and extend to the processing station for the dried cable. Drying holes leading to the inside of the drying channel are also provided on the installation housing, and a gas source can be connected to the drying holes through a pipeline and hot air can be transported through the pipeline and the drying holes to the inside of the drying channel to dry the cable in the drying channel; because cable production lines often produce cables of different thicknesses according to production requirements, multiple dryers with different drying channel widths need to be prepared on the production line.

[0004] However, since existing cable production lines generally adopt a continuous production method for the entire cable, and the installation housing is sleeved on the entire cable, when producing cables of different thicknesses and the dryer needs to be replaced, workers need to first cut off the entire cable at the part where the thickness changes, then collect the cut-off cable, and finally pull the cable left on the production line through the drying channel and subsequent cable processing stations in sequence, making the replacement process of existing dryers relatively cumbersome.

[0005] In view of this, an adjustable dryer is needed. Utility Model Content

[0006] In order to solve the problem that the existing dryer needs to cut off and re-pull the cable on the cable production line during replacement, and the replacement process is relatively cumbersome, the present application provides an adjustable dryer.

[0007] The present application provides an adjustable dryer, adopting the following technical solution: including a drying sleeve and a support base, the drying sleeve includes a first splicing member and a second splicing member, the first splicing member is disposed above the support base, the second splicing member is detachably connected to the first splicing member, and the second splicing member and the first splicing member can be spliced to form a drying channel therebetween, a cable can pass through the drying channel, a hot air channel is provided on the inner wall of the drying channel, the air outlet end of the hot air channel leads to the inside of the drying channel, and the air inlet end of the hot air channel is connected to a gas source capable of providing hot air through a pipeline.

[0008] By adopting the above technical solution, when it is necessary to change the thickness of the cable to produce cables of different specifications and it is necessary to replace the drying channels with different widths, the user can first remove the second fitting on the drying sleeve to be replaced and the drying sleeve to be used from the first fitting, then remove the cable from the first fitting on the drying sleeve to be replaced and place it on the first fitting on the drying sleeve to be used, and finally reinstall the second fitting on the drying sleeve to be used, thus completing the quick replacement of the adjustable air dryer. As a result, when replacing the adjustable air dryer, it is not necessary to cut off and re-tract the cable on the cable production line, and the replacement process is very fast and convenient.

[0009] Specifically, one side of the second fitting is hinged to the first fitting, a hook is provided on the other side of the second fitting, and a buckle adapted to the hook is provided on the first fitting.

[0010] By adopting the above technical solution, the hinged setting enables the side of the second fitting provided with the hook to rotate around the first fitting, and the settings of the hook and the buckle enable the second fitting to be connected to the first fitting by connecting the hook and the buckle.

[0011] Specifically, the hot air channel includes a first air storage cavity and a second air storage cavity. The first air storage cavity is arranged inside the first fitting, the second air storage cavity is arranged inside the second fitting. Air inlet holes and air outlet holes leading to the drying channel are formed on the inner walls of the first air storage cavity and the second air storage cavity. One side of the air inlet hole far from the drying channel is connected to the air source through a pipeline.

[0012] By adopting the above technical solution, the air source can blow hot air into the first air storage cavity and the second air storage cavity through the air inlet holes on the first air storage cavity and the second air storage cavity. These hot airs will first be dispersed into each air outlet hole and then leave the air outlet hole and blow into the drying channel to dry the cable in the drying channel.

[0013] Further, the inner part of the drying sleeve forms the drying channel. A plurality of air outlet holes are formed on the inner walls of the first air storage cavity and the second air storage cavity, and the air outlet holes are arranged at equal intervals around the central axis of the drying sleeve.

[0014] By adopting the above technical solution, the arrangement of the air outlet holes makes the hot air blown towards the cable from the air outlet holes arranged at equal intervals around the central axis of the drying sleeve, and then makes the wind force received by the whole body of the cable in the drying channel relatively stable, ensuring that the cable will not repeatedly jump in the drying channel.

[0015] Specifically, the support base includes a base and a support rod. A sliding sleeve is provided on the base. The bottom end of the support rod is inserted into the sliding sleeve and can slide in the vertical direction. The top end of the support rod is detachably connected to the first fitting.

[0018] By adopting the above technical solution, the limiting block can be inserted into the limiting groove and abut against the groove walls at both ends of the limiting groove, so as to limit the range of up and down movement of the support rod through the cooperation of the limiting block and the limiting groove.

[0019] Further, a positioning post is provided at the top of the support rod. A support surface is provided on the first fitting. A positioning hole adapted to the positioning post is formed in the support surface. The top of the support rod can abut against the support surface and stack the first fitting on the support rod, and the positioning post is inserted into the positioning hole.

[0020] By adopting the above technical solution, the user can directly remove the first fitting from the support rod or directly stack the first fitting on the support rod; the positioning post can cooperate with the positioning hole to position the stacking position of the first fitting, so as to facilitate the rapid placement of the first fitting.

[0021] Further, the first fitting includes a clamping block, a pull rod and a compression spring. A receiving groove is formed in the inner wall of the positioning hole. The clamping block is arranged in the receiving groove. A connecting hole leading to the outside is formed in the groove wall on one side of the receiving groove away from the groove opening. One end of the pull rod passes through the connecting hole and extends into the receiving groove and is connected to the clamping block.

When the positioning column is inserted into the positioning hole, the compression spring can apply a force to the clamping block to make it approach the clamping groove, and the clamping block is inserted into the clamping groove and abuts against the inner wall of the clamping groove.

[0023] By adopting the above technical solution, the clamping block can cooperate with the clamping groove to clamp the positioning column, so that the first assembled part is not easily detached from the support rod.

Detailed implementation mode

[0032] The following is further described with reference to the attached Figures 1-5 drawings:

[0033] Referring to Figure 1 and Figure 2 FIGS., an adjustable hair dryer provided by the present application includes a drying sleeve 1 and a support base 2. A drying channel 13 for passing a cable is formed inside the drying sleeve 1. The width of the drying channel 13 can be set according to the thickness of the cable to be dried. For example, the width of the drying channel 13 is set to 12 mm to adapt to a cable with a diameter of 10 mm. The drying sleeve 1 is divided into a first fitting 11 and a second fitting 12 by a horizontal plane along its own length direction. The cross-sections of the first fitting 11 and the second fitting 12 are both semi-circular. One side of the second fitting 12 is hinged above the first fitting 11. A hook 121 is provided on the other side of the second fitting 12. A buckle 111 adapted to the hook 121 is provided on the first fitting 11, so that the side of the second fitting 12 provided with the hook 121 can rotate around the first fitting 11 to open and close the drying channel 13, and the user can limit the rotation of the second fitting 12 by connecting the hook 121 with the buckle 111.

[0034] Referring to Figure 3 and Figure 4 FIGS., a hot air channel 14 is provided inside the drying sleeve 1. The hot air channel 14 includes a first air storage cavity 141 and a second air storage cavity 142. The first air storage cavity 141 is arranged inside the first fitting 11, and the second air storage cavity 142 is arranged inside the second fitting 12. Air inlet holes 143 and air outlet holes 144 leading to the drying channel 13 are formed on the inner walls of the first air storage cavity 141 and the second air storage cavity 142. One side of the air inlet hole 143 far from the drying channel 13 is connected to an air source 3 capable of providing hot air through a pipeline. The air source 3 can be a blast boiler, so as to be able to blow hot air into the first air storage cavity 141 and the second air storage cavity 142 through the blast boiler. These hot airs will first be dispersed into each air outlet hole 144, and then leave the air outlet hole 144 and enter the drying channel 13 to dry the cable in the drying channel 13.

[0035] Specifically, the number of air outlet holes 144 formed on the inner walls of the first air storage cavity 141 and the second air storage cavity 142 can be set according to the width of the drying channel 13. For example, for a drying channel 13 with a width of 30 mm, 3 air outlet holes 144 are provided, and for a drying channel 13 with a width of 50 mm, 4 air outlet holes 144 are provided; each air outlet hole 144 is arranged at equal intervals around the central axis of the drying sleeve 1, so that the hot air blown from the air outlet holes 144 to the cable is arranged at equal intervals around the central axis of the drying sleeve 1. Subsequently, the wind force received by the whole body of the cable in the drying channel 13 is relatively stable, ensuring that the cable will not repeatedly jump in the drying channel 13.

[0036] See Figure 1 and Figure 4 , the support base 2 includes a base 21 and a support rod 22. A sliding sleeve 211 is provided on the base 21. The bottom end of the support rod 22 is inserted into the sliding sleeve 211 and can slide in the vertical direction. A fixing screw hole leading to the inside of the sleeve is formed on the side wall of the sliding sleeve 211. A tightening bolt 2111 is screwed into the fixing screw hole. The tightening bolt 2111 can abut the rod body of the support rod 22 between the screw end of the tightening bolt 2111 and the inner wall of the sliding sleeve 211, so that the user can adjust the distance between the support rod 22 and the base 21 through the cooperation of the tightening bolt 2111 and the sliding sleeve 211, and then align the central axis of the drying sleeve 1 with the central axis of the cable; a limiting groove 221 is vertically formed on the rod body of the support rod 22, and a limiting block 2112 is provided on the inner wall of the sliding sleeve 211. The limiting block 2112 is inserted into the limiting groove 221 and can abut against the groove walls at the top and bottom of the limiting groove 221, so as to limit the amplitude of the up and down movement of the support rod 22 through the cooperation of the limiting block 2112 and the limiting groove 221.

[0037] See Figure 4 and Figure 5, a positioning post 222 is provided at the top of the support rod 22. The first fitting 11 includes a clamping block 112, a pull rod 113, and a compression spring 114. A support surface is provided horizontally at the bottom of the first fitting 11, and a positioning hole is opened on the support surface. The user can directly stack the drying sleeve 1 with drying channels 13 of different thicknesses on the top of the support rod 22, and quickly position the drying sleeve 1 by inserting the positioning post 222 into the positioning hole; a receiving groove is opened on the inner wall of the positioning hole, the clamping block 112 is arranged in the receiving groove, a connecting hole leading to the outside is opened on the side wall of the receiving groove away from the notch, one end of the pull rod 113 passes through the connecting hole and extends into the receiving groove to be connected with the clamping block 112, the compression spring 114 is arranged between the side of the clamping block 112 away from the positioning hole and the wall of the receiving groove, and a clamping groove is opened on the column body of the positioning post 222. When the positioning post 222 is inserted into the positioning hole, the compression spring 114 will apply a force to the clamping block 112 to move it closer to the clamping groove and make the clamping block 112 insert into the clamping groove, so that the drying sleeve 1 can be clamped with the support rod 22 through the cooperation of the clamping block 112 and the clamping groove, preventing the drying sleeve 1 from falling off the support rod 22 due to vibration; when it is necessary to disassemble the drying sleeve 1, the user can first pull the pull rod 113 to pull the clamping block 112 out of the clamping groove, and then remove the drying sleeve 1 from the support rod 22.

[0038] Preferably, an inclined surface can be provided at the top of the positioning post 222, and the inclined surface inclines downward and toward the direction close to the clamping groove, so that when the positioning post 222 is inserted into the positioning hole, the clamping block 112 can retract into the receiving groove along the inclined surface.

[0039] The using process of an adjustable hair dryer provided by the present application is as follows:

[0040] When it is necessary to change the thickness of the cable to produce cables of different specifications and it is necessary to replace the drying channels 13 with different widths, the user can first remove the buckles 111 on the drying sleeve 1 to be replaced and the drying sleeve 1 to be used from the hooks 121, then turn the second fitting 12 on the drying sleeve 1 to be replaced around the first fitting 11 to the open state and remove the cable from the opened drying channel 13, then pull the pull rod 113 on the first fitting 11 to pull the clamping block 112 out of the clamping groove and remove the first fitting 11 from the support rod 22, then install the drying sleeve 1 to be used on the support rod 22, then move the cable into this drying sleeve 1 and fasten the buckle 111 on the drying sleeve 1 to be used to the hook 121, and finally remove the pipeline of the air source 3 from the air inlet hole 143 on the drying sleeve 1 to be replaced and install it on the air inlet hole 143 on the drying sleeve 1 to be used, and the quick replacement of the adjustable hair dryer can be completed, so that the adjustable hair dryer does not need to cut off and re-tract the cable on the cable production line during replacement, and the replacement process is very fast and convenient.

[0041] The working principle of an adjustable hair dryer of the present application during use is specifically as follows:

[0042] When it is necessary to change the thickness of the cable to produce cables of different specifications and it is necessary to replace the drying channel 13 with a different width, the user can first remove the fastening buckle 111 on the drying sleeve 1 to be replaced and the drying sleeve 1 to be used from the hanging hook 121, then turn the second fitting 12 on the drying sleeve 1 to be replaced around the first fitting 11 to the open state and remove the cable from the opened drying channel 13, then pull the pull rod 113 on the first fitting 11 to pull out the clamping block 112 from the clamping groove and remove the first fitting 11 from the support rod 22, then install the drying sleeve 1 to be used on the support rod 22, then place the cable into this drying sleeve 1 and fasten the fastening buckle 111 on the drying sleeve 1 to be used to the hanging hook 121, and finally remove the pipeline of the air source 3 from the air inlet hole 143 on the drying sleeve 1 to be replaced and install it on the air inlet hole 143 on the drying sleeve 1 to be used, thus completing the rapid replacement of the adjustable hair dryer, so that there is no need to cut off and re-tract the cable on the cable production line during the replacement of the adjustable hair dryer, and the replacement process is very fast and convenient.
