Description

Technical Field

[0001] This utility model relates to the field of pipe joint technology, specifically a pull-out pipe joint for cylindrical paper packaging boxes. Background Technology

[0002] Paper box packaging achieves product protection and transportation convenience through diverse structural designs, including three core forms: portable, habitual, and single-use small packaging. Among them, cylindrical paper packaging boxes have a round structure and are commonly seen in instant noodle tubs and cylindrical takeout boxes.

[0003] After processing, cylindrical paper packaging boxes are often transported to the stacking and packing area via a pull-out pipe joint and an overhead pipe. The pull-out pipe joint uses Bernoulli's principle to pull the cylindrical paper packaging box from the pallet and move it along the pipe. However, currently, pull-out pipe joints generally only have an air inlet channel on one side, which makes it easy for the cylindrical paper packaging box to become tilted and stuck when it is pulled out. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Summary of the Invention

[0004] The purpose of this utility model is to provide a pull-out pipe joint for cylindrical paper packaging boxes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pull-out pipe connector for a cylindrical paper packaging box, comprising a cylindrical body and a bottom pressure ring. A thickened platform is provided at the lower part of the cylindrical body. An air inlet channel is provided on one side of the thickened platform. An annular groove is provided inside the thickened platform. The bottom of the annular groove is connected to the outside of the thickened platform, and one side of the annular groove is connected to the air inlet channel. Several guide air channels are provided inside the thickened platform at the top of the annular groove. The guide air channels are all arranged obliquely and distributed in a ring within the thickened platform. The distance between adjacent guide air channels is the same. The guide air channels are all connected to the interior of the cylindrical body. An annular protrusion is provided on the upper surface of the bottom pressure ring. The bottom pressure ring is located at the bottom of the cylindrical body and connected to the thickened platform. The annular protrusion is inserted into the annular groove.

[0006] Preferably, the present invention provides a pull-out pipe joint for a cylindrical paper packaging box, wherein a reinforcing boss is provided on the outer surface of the cylinder along the circumferential direction.

[0007] Preferably, the present invention provides a removable pipe joint for a cylindrical paper packaging box, wherein a connecting sleeve is provided on the outer surface of the thickened platform at the air inlet channel.

[0008] Preferably, in the pull-out pipe joint for cylindrical paper packaging boxes provided by this utility model, the inner diameter of the bottom pressure ring is not less than the inner diameter of the cylinder.

[0009] Preferably, the present invention provides a pull-out pipe joint for a cylindrical paper packaging box, wherein the inner and outer sides of the upper surface of the annular boss are chamfered.

[0010] Preferably, the present invention provides a pull-out pipe joint for a cylindrical paper packaging box, wherein the cylindrical body is provided with connecting plates on both sides of the thickened platform.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The lower surface of the thickened platform at the bottom of the cylinder has an annular groove. The annular groove is sealed by the annular protrusion of the bottom pressure ring. Several guide air channels are extended from the top of the annular groove in a ring. This method of blowing air evenly into the cylinder has a better conveying effect than the traditional single-sided air intake structure, and avoids the situation where cylindrical paper packaging boxes get stuck.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a pull-out pipe connector for a cylindrical paper packaging box, including a cylindrical body 1 and a bottom pressure ring 2. A thickened platform 3 is provided at the lower part of the cylindrical body 1. An air inlet channel 4 is opened on one side of the thickened platform 3. An annular groove 5 is opened inside the thickened platform 3. The bottom of the annular groove 5 is connected to the outside of the thickened platform 3, and one side of the annular groove 5 is connected to the air inlet channel 4. A connecting sleeve 9 is provided on the outer surface of the thickened platform 3 at the air inlet channel 4 to connect with an external air inlet pipe. Several guide air ducts are opened at the top of the annular groove 5 inside the thickened platform 3. The guide air channels 6 are arranged obliquely and distributed in a ring within the thickened platform 3. The distance between adjacent guide air channels 6 is the same. The guide air channels 6 are all connected to the interior of the cylinder 1. The bottom pressure ring 2 is provided with an annular protrusion 7 on its upper surface. The bottom pressure ring 2 is located at the bottom of the cylinder 1 and connected to the thickened platform 3. The inner diameter of the bottom pressure ring 2 is not less than the inner diameter of the cylinder 1 to ensure that the cylindrical paper packaging box can pass smoothly through the bottom pressure ring 2. The annular protrusion 7 is inserted into the annular groove 5. The inner and outer sides of the upper surface of the annular protrusion 7 are chamfered to facilitate the insertion of the annular protrusion 7 into the annular groove 5. The outer surface of the cylinder 1 is also provided with a reinforcing boss 8 along the circumferential direction to ensure the structural strength and stability of the cylinder 1. The cylinder 1 is provided with connecting plates 10 on both sides of the thickened platform 3, which facilitates connection and support with the external support.

[0016] Installation Method and Operating Principle: A cylinder body 1 and a bottom pressure ring 2 are fabricated. An annular groove 5 is formed on the lower surface of the thickened platform 3 of the cylinder body 1. Then, several oblique guide air channels 6 are formed inside the thickened platform 3, located on the inner side of the upper end of the annular groove 5. Next, an air inlet channel 4 is formed on the side wall of the thickened platform 3, and the air inlet channel 4 is connected to one side of the annular groove 5. Simultaneously, an air inlet interface is welded to the outside of the thickened platform 3, located at the air inlet channel 4, completing the fabrication of the cylinder body 1. Finally, the annular protrusion 7 of the bottom pressure ring 2 is inserted into the annular groove 5 of the thickened platform 3, and hammered with a tool until the upper surface of the bottom pressure ring 2 is tightly connected to the thickened platform 3 at the bottom of the cylinder body 1, completing the assembly. Before use, two connecting plates 10 are welded to both sides of the thickened platform 3. During use, the connecting plates 10 are connected to the bracket, and the upper end of the cylinder body 1 is fitted with a plastic pipe. The connecting sleeve 9 is connected to the hose, and the other end of the hose is connected to the air compressor. When the air compressor generates continuous high-pressure gas, the high-pressure gas enters the annular groove 5 from the air inlet channel 4, and then is blown out obliquely from the inside of the cylinder 1 through various guide air channels 6. After the cylindrical paper packaging box is pressed against the bottom plate, it is lifted by the tooling and enters the cylinder 1. Using Bernoulli's principle, the cylindrical paper packaging box will be blown from the cylinder 1 into the plastic pipe and transported along the plastic pipe to the stacking and packaging area. This utility model has a reasonable structure. The lower surface of the thickened platform 3 at the bottom of the cylinder 1 is provided with an annular groove 5. The annular groove 5 is sealed by the annular protrusion 7 of the bottom pressure ring 2. Several guide air channels 6 are provided at the top of the annular groove 5 in a ring distribution. This method of blowing air evenly into the cylinder 1 has a better conveying effect than the traditional single-sided air inlet structure and avoids the cylindrical paper packaging box from getting stuck.
