Description

Technical Field

[0001] The utility model relates to peripheral equipment of an extruder, specifically to a blowing device for connecting a cooling water tank of an extruder. Background Art

[0002] During the extrusion of wire and cable, the plastic is heated and plasticized at high temperature by the head screw, then wrapped on the surface of the cable core. After being fully cooled in the cooling water tank, the residual water droplets on the surface are dried before the surface marking and printing of the finished cable can be carried out. The marking should be clear, easy to identify, and resistant to rubbing.

[0003] However, the existing blowing device has a poor drying effect. It can only blow away the water droplets on the upper surface of the cable and cannot dry the cable 360 degrees in all directions, resulting in incomplete and unclear marking and printing, and water droplets dripping onto the ground, affecting the on-site environment.

In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Embodiment 1: The specific structure of the present invention is as follows:

[0029] Please refer to the attached Figures 1-3 , a blowing device for connecting the cooling water tank of an extruder of the present invention, comprising:

[0030] A box body, which is installed at the end of the cooling water tank 5 and has a channel for the linear product 11 to pass through. At this channel, there are a plurality of air outlets 10 with different blowing angles and all pointing to the path of the linear product. The air outlets 10 are communicated with the inner cavity of the box body. In this embodiment 1, the linear product 11 is taken as an example of a cable for illustration. The channel is a semi-circular channel, and the path of the cable is inside the semi-circular channel. Since the cable passes through the cooling water tank 5 after extrusion, water droplets and water stains will be carried on the surface of the cable, and these water droplets and water stains need to be removed;

[0031] An air inlet pipe communicated with the inner cavity of the box body, which is connected to the bottom of the box body and has a vertical pipeline 13 and a branch pipeline 14 connected to the vertical pipeline 13 on the side. The branch pipeline 14 is connected to the air source, and the vertical pipeline 13 is used for draining water. The water droplets on the cable are blown off and enter the groove surface formed by the upper arc plate 15 and the water retaining step 12, then flow into the inner cavity of the box body through the air outlet 10, and finally are discharged from the vertical pipeline 13. The branch pipeline 14 is connected to the air source, and the air source is a blower;

[0032] A plurality of threaded interfaces 9 communicated with the inner cavity of the box body are provided on both top planes of the box body. The threaded interfaces 9 are used to connect flexible air outlet nozzles. After the air outlet nozzles are adjusted in angle, the water droplets on the side and upper surface of the cable can be blown off, and the water stains on the surface of the cable can be dried. As Figure 1 shown, 3 threaded interfaces 9 are provided on each top plane, that is, six air outlet nozzles can be installed. The six air outlet nozzles are flexible nozzles. After their angles are adjusted, they cooperate with the two air outlets 10 to make the passing cable be covered by wind without dead angles, achieving the purpose of efficiently drying the cable.

[0033] A preferred technical solution of this embodiment: The box body is a semi - toroidal structure, its inner arc surface faces upward, and the space above the inner arc surface forms the channel.

[0034] The box body includes:

[0035] A bottom arc plate 1, which is formed by bending a plate body into a first arc panel. The bottom arc plate 1 is made by pressing and bending a 3 - mm - thick stainless - steel plate. There is a hole at its lower end, and the air inlet pipe is welded to this hole. The water inlet pipe is a stainless - steel pipe. Threaded holes are evenly arranged at the edge of the bottom arc plate 1;

[0036] Two side cover plates 2, both of which are semi - toroidal plates and are connected and fixed to the two arc edges on both sides of the bottom arc plate 1. There are steps on the two arc edges at the relative side surfaces of the side cover plates 2. The bottom arc plate 1 covers the lower bottoms of the two side cover plates 2 along the steps and is then fixed by screws 6;

[0037] An upper arc plate 15, which is formed by bending a plate body into a second arc panel. The second arc panel is connected to the inner arc edges of the two side cover plates 2 to form the inner arc surface. The two ends of the assembled body formed by the bottom arc plate 1, the two side cover plates 2, and the upper arc plate 15 form rectangular openings. The upper arc plate 15 is connected to the upper arc openings of the two side cover plates 2 and is fixed by screws 6;

[0038] Two cover plates 3, which are respectively connected to the two rectangular openings. The cover plates 3 are the top planes of the box body. The cover plates 3 are connected and fixed to the rectangular openings through gaskets 7 and bolts 8.

[0039] A preferred technical solution of this embodiment: There is a semi - toroidal rubber pad 4 between the facing connection surfaces of the box body and the cooling water tank 5. The box body and the cooling water tank 5 are also connected and fixed through gaskets 7 and bolts 8.

[0040] A preferred technical solution of this embodiment: There are two air outlets 10. The two air outlets 10 are arranged at an angle and symmetrically on the inner arc surface. The included angles between the two air outlets 10 and the horizontal plane are both 45 degrees. The two air outlets 10 both point to the cable. Therefore, the blown air points to the cable.

[0041] A preferred technical solution of this embodiment: On both arc edges of the inner arc surface, there are water - retaining steps 12 that are higher than the inner arc surface. A groove surface is formed between the water - retaining steps 12 and the inner arc surface to prevent the falling water from dropping onto the floor.

[0042] In summary, the blowing device of the present utility model is installed at the end of the cooling water tank. When the cable passes through this blowing device, it can achieve 360-degree all-round drying of the water stains on the surface of the cable and blowing off the water droplets on the surface of the cable, making the cable markings clear and easy to identify. The blowing device of the present utility model also has a water collection structure. The water droplets on the surface of the cable are blown off and fall into the trough body where the inner arc surface is located, then leak into the inner cavity of the box body through the air outlet holes, and finally are discharged through the vertical pipeline. This water collection structure protects the surrounding environment and prevents the floor from slipping. Multiple threaded interfaces are provided on the two top planes of the blowing device of the present utility model. The threaded interfaces are used to connect flexible air outlet nozzles. After the angle of the air outlet nozzles is adjusted, the water droplets on the side and upper surface of the cable can be blown off, and the water stains on the surface of the cable can be dried.
