Description

Technical Field

[0001] This utility model relates to the field of optical cable manufacturing technology, specifically a constant temperature blowing-off drool device. Background Technology

[0002] When optical cables are extruded for sheathing, due to poor plasticization of the material or impurities, external material and impurities may accumulate at the extrusion port. If these impurities are not removed in time, they may cause sheath bulging or sheath tearing.

[0003] Chinese patent CN212554962U discloses a constant-temperature drool removal device, including a blowing mechanism and an air supply assembly. The blowing mechanism includes an air chamber, multiple air holes communicating with the air chamber, and a through hole for the outer sheath of an optical cable to pass through. The air supply assembly supplies air to the air chamber, and the air holes are inclined and blow air onto the outer sheath passing through the through hole. This utility model's drool removal device at the mold exit, by setting up a blowing mechanism and an air supply assembly to supply air to the blowing mechanism, and by setting an air chamber and air holes on the blowing mechanism, can blow air onto the surface of the outer sheath through the air holes, thereby blowing away the drool located on the surface of the outer sheath, achieving automatic drool removal and improving the production quality of the outer sheath.

[0004] However, existing devices have drawbacks in practical applications. Some sheath materials have insufficient fluidity due to insufficient plasticizer, which causes the blowing surface to become dull due to sudden temperature drop during blowing. In addition, the blowing range cannot be controlled, resulting in poor blowing effect. Therefore, a constant temperature blowing device is needed to remove drool. Utility Model Content

[0005] The purpose of this invention is to provide a constant temperature blowing-off drooling device to solve the problems of uneven surface caused by sudden temperature drop during blowing in existing devices, and damage to the outer sheath caused by uncontrollable blowing range.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature drool removal device, comprising an extruder head, wherein a drool removal mechanism is provided on the extruder head; the drool removal mechanism comprises two slides, which are respectively fixedly installed on the upper and lower sides of the extruder head, and positioning bolts are rotatably installed on the slides, and a connecting frame is slidably installed in the middle of the slides, an air blowing pipe is fixedly installed on the upper connecting frame, and an air suction pipe is fixedly installed on the lower connecting frame, a booster air blowing pump and a booster air suction pump are respectively fixedly installed on the air blowing pipe and the air suction pipe, a heating grid is fixedly installed on the output end of the booster air blowing pump, and a filter plug is fastened to one end of both the air blowing pipe and the air suction pipe.

[0007] Preferably, the connecting bracket is threaded onto the positioning bolt, and the connecting bracket is slidably mounted on the slide block.

[0008] Preferably, the front ends of both the blowing pipe and the suction pipe are composed of semi-circular arc tubes, and the semi-circular arc tubes are on the same straight line as the center of the extruder head.

[0009] Preferably, the blowing pipe and the suction pipe are fixedly connected to the booster blowing pump and the booster suction pump via high-temperature resistant hoses.

[0010] Preferably, the air blowing pipe is provided with an air adjustment mechanism, which includes a plurality of air cylinders and an air groove. The plurality of air cylinders are fixedly installed on the lower side of the air blowing pipe, and the air groove is opened on the upper side of the air intake pipe. An extension pipe is fixedly installed at one end of the air cylinder, and a threaded plate is fixedly installed at one end of the extension pipe. A threaded shank is threadedly installed on the threaded plate, and a rubber stopper is fixedly installed at one end of the threaded shank.

[0011] Preferably, several of the air cylinders are fixedly installed at equal intervals on the air blowing pipe, and the air cylinders are fixedly installed on the air blowing pipe in a protruding manner.

[0012] Preferably, a strip-shaped groove is provided on one side of the air cylinder, the strip-shaped groove is oriented toward the center of the front end of the air pipe, and the rubber plug is adapted to the strip-shaped groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) This constant temperature blowing-off device moves the connecting frame in the slide by controlling the positioning bolts, thereby changing the distance between the blowing pipe and the suction pipe and the center position of the extruder head. This ensures that gas of a certain pressure is blown out through the blowing pipe and the air cylinder, breaking up the drool at the front end of the extruder head and further drying it into fragments, which are then sucked into the suction pipe through the air groove. In use, the gas is blown out by the booster blowing pump and heated to a constant temperature by the heating grid before being sprayed out. Under the action of the booster suction pump, the drool fragments at the outlet of the head are extracted, achieving the effect of blowing off drool from the optical cable sheath. 2) This constant temperature drool removal device uses several air cylinders fixedly installed at equal intervals on the lower side of the air blowing pipe, and an extension tube fixedly installed at one end of the air cylinder. The rubber plug moves inside the air cylinder and the extension tube under the support of the threaded handle, thereby changing the size of the air outlet on the air cylinder and changing the air outlet range of the air cylinder. When in use, the efficiency of drool removal by adjusting the size of the air outlet on the air cylinder can be improved. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] Combination Figures 1-3 A constant temperature drool removal device includes an extruder head 1, on which a drool removal mechanism 2 is provided. The drool removal mechanism 2 includes two slides 201, which are fixedly installed on the upper and lower sides of the extruder head 1, respectively. A positioning bolt 202 is rotatably installed on the slides 201, and a connecting frame 203 is slidably installed in the middle of the slides 201. An air blowing pipe 204 is fixedly installed on the upper connecting frame 203, and an air suction pipe 205 is fixedly installed on the lower connecting frame 203. A booster air blowing pump 206 and a booster air suction pump 207 are fixedly installed on the air blowing pipe 204 and the air suction pipe 205, respectively. A heating grid 208 is fixedly installed on the output end of the booster air blowing pump 206, and a filter plug 209 is fastened to one end of the air blowing pipe 204 and the air suction pipe 205.

[0022] The connecting frame 203 is threaded onto the positioning bolt 202 and is also slidably mounted on the slide block 201, allowing it to move up and down along the slide block 201 under the control of the positioning bolt 202. The front ends of both the air blowing pipe 204 and the air suction pipe 205 are composed of semi-circular arc tubes, and these semi-circular arc tubes are aligned with the center of the extruder head 1, ensuring that the distance between the air blowing pipe 204 and the air suction pipe 205 at the center of the extruder head 1 is the same. 5. Both the booster air pump 206 and the booster air intake pump 207 are fixedly connected by high-temperature resistant hoses, so that the hot air generated by the heating grid 208 in conjunction with the booster air pump 206 can flow between the air blowing pipe 204 and the air intake pipe 205. During use, the filter plug 209 can be removed periodically for cleaning. The filter plug 209 is only a simple illustration here. Existing tubular filters are preferred, but they can also be made by adding a filter screen to a suitable tube. They can intercept large particulate impurities and debris in the air. Example 2

[0023] See Figure 4 and Figure 5 An air conditioning mechanism 3 is provided on the air blowing pipe 204. The air conditioning mechanism 3 includes several air cylinders 301 and air grooves 302. Several air cylinders 301 are fixedly installed on the lower side of the air blowing pipe 204. The air grooves 302 are opened on the upper side of the air intake pipe 205. An extension pipe 303 is fixedly installed on one end of the air cylinder 301. A threaded plate 304 is fixedly installed on one end of the extension pipe 303. A threaded shank 305 is threadedly installed on the threaded plate 304. A rubber plug 306 is fixedly installed on one end of the threaded shank 305.

[0024] Several air cylinders 301 are fixedly installed at equal intervals on the air blowing pipe 204, and the air cylinders 301 are fixedly installed on the air blowing pipe 204 in a protruding manner. A strip-shaped groove is opened on one side of the air cylinder 301, and the strip-shaped groove faces the center position of the front end of the air blowing pipe 204. The strip-shaped groove is used to spray hot air to the front end of the extruder head 1. The rubber plug 306 is adapted to the strip-shaped groove. By controlling the threaded handle 305, the rubber plug 306 can be moved in the air cylinder 301, thereby changing the exposed length of the strip-shaped groove and changing the air flow rate of the air cylinder 301.

[0025] In actual operation, the connecting frame 203 moves within the slide 201 by controlling the positioning bolt 202, thereby changing the distance between the air blowing pipe 204 and the suction pipe 205 and the center position of the extruder head 1. This ensures that the air blowing pipe 204 blows air into the extruder head 1 and the suction pipe 205 draws air out. During use, the booster air pump 206 blows out gas at a certain pressure, which is then heated to a constant temperature by the heating grid 208 and sprayed out. This can break up the drool at the front end of the extruder head and further dry it into fragments. Under the action of the booster suction pump 207, the drool fragments at the outlet of the extruder head are extracted. Most of the drool fragments are drawn to the filter plug 209, and a small part remains in the suction pipe 205. During use, the filter plug 209 can be removed periodically for cleaning, thus achieving the effect of blowing away drool from the optical cable sheath. By fixing several air cylinders 301 at equal intervals on the lower side of the air blowing pipe 204, and fixing an extension pipe 303 at one end of the air cylinder 301, the rubber plug 306 moves within the air cylinder 301 and the extension pipe 303 under the support of the threaded handle 305, thereby changing the size of the air outlet on the air cylinder 301 and changing the air outlet range of the air cylinder 301. In use, by adjusting and changing the size of the air outlet on the air cylinder 301, the efficiency of the sheath in blowing away drool can be improved.
