Description

Technical Field

[0001] This utility model relates to the field of round tube adhesive coating technology, and in particular to an adhesive collection device for round tube adhesive coating. Background Technology

[0002] When applying adhesive to the round tube of heat shrink sleeve, the inability to effectively control the hot melt adhesive at the tail end leads to severe adhesive overflow, resulting in excessive thickness and adhesive buildup. For products with adhesive buildup at the tail end, the excessively thick and adhesive-covered sections need to be cut off during slitting. Most products require a 3-5 cm trimming at the tail end, which wastes both substrate and adhesive. The cut products also require manual trimming, increasing both operational difficulty and labor costs. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a glue collection device for coating round tubes.

[0004] The purpose of this utility model is achieved through the following technical solution: a glue collection device for applying glue to a round tube, comprising a cylinder base, the cylinder base being disposed at the end of a three-way connector, the other end of the three-way connector being connected to the interior of a glue-applying rod, the other end of the glue-applying rod being provided with a connecting rod, the other end of the connecting rod being provided with a glue-applying head, the cylinder being mounted on the cylinder base, the piston rod on the cylinder being connected to a telescopic rod, and the telescopic rod passing through the cylinder base, the three-way connector and the glue-applying rod in sequence, the end of the telescopic rod being provided with a plug, and the plug being used to control the opening and closing of the through hole in the connecting rod.

[0005] Preferably, the connecting rod also has a receiving cavity, which is connected to the through hole, and the inner diameter of the receiving cavity is larger than the inner diameter of the through hole, and the diameter of the plug is the same as the inner diameter of the through hole.

[0006] Preferably, a sealing cavity is provided inside the cylinder base, and a sealing ring is provided inside the sealing cavity. The sealing ring is located outside the telescopic rod, and a sealing pressure plate is provided at one end of the cylinder base, with the pressing end of the sealing pressure plate located inside the sealing cavity.

[0007] This utility model has the following advantages: The utility model uses a cylinder to drive the end plug of the telescopic rod to move horizontally, thereby controlling the opening and closing of the through hole in the connecting rod through the plug, thus sealing the excess glue in the glue-applying rod, preventing glue overflow at the tail end when applying glue to the round tube, and ensuring that there is no excess glue on the glue-applying head when each round tube to be glued enters the glue-applying head, replacing the need for manual cutting in the later stage, reducing labor costs, and improving production efficiency.

[0017] In this embodiment, as Figure 1 As shown, a glue collection device for applying glue to a round tube includes a cylinder base 3, which is located at the end of a three-way connector 5. The other end of the three-way connector 5 is connected to the inside of a glue-applying rod 7. A connecting rod 8 is provided at the other end of the glue-applying rod 7, and a glue-applying head 11 is provided at the other end of the connecting rod 8. A cylinder 1 is mounted on the cylinder base 3, and the piston rod on the cylinder 1 is connected to a telescopic rod 6. The telescopic rod 6 passes through the cylinder base 3, the three-way connector 5, and the glue-applying rod 7 in sequence. A plug 10 is provided at the end of the telescopic rod 6, and the plug 10 is used to control the opening and closing of the through hole 9 in the connecting rod 8. The cylinder 1 drives the plug 10 at the end of the telescopic rod 6 to move horizontally, thereby controlling the opening and closing of the through hole 9 in the connecting rod 8. This seals the excess glue in the glue applicator 7, preventing glue overflow at the tail end when applying glue to the round tube. It also ensures that each round tube entering the glue applicator is free of excess glue, replacing manual cutting later, reducing labor costs, and improving production efficiency. In this embodiment, the glue applicator 11, glue applicator 7, and tee connector are all existing products, and no improvements have been made; therefore, they will not be described further.

[0018] Furthermore, such as Figure 2 As shown, the connecting rod 8 also has a receiving cavity 12, which is connected to the through hole 9. The inner diameter of the receiving cavity 12 is larger than the inner diameter of the through hole 9, and the diameter of the plug 10 is the same as the inner diameter of the through hole 9. Specifically, when adhesive needs to be applied, the worker first places the round tube onto the adhesive applicator 7 and starts the external adhesive supply machine (not shown in the figure). The adhesive is supplied into the adhesive applicator 7 through the three-way connector 5. At this time, the cylinder 1 drives the plug 10 to move forward, so that the plug 10 is located in the receiving cavity 12, opening the through hole 9. The adhesive in the adhesive applicator 7 flows into the adhesive applicator head 11 through the through hole 9, and finally flows out through the adhesive applicator head 11 to coat the inner wall of the round tube (during the adhesive application process, the worker pulls the round tube to make the adhesive applicator 7 exit the round tube, thereby applying adhesive to the inner wall of the round tube). When the adhesive reaches the end of the round tube, the cylinder 1 drives the plug 10 to move backward, so that the plug 10 is located in the through hole 9. Since the diameter of the plug 10 is the same as the inner diameter of the through hole 9, the through hole 9 can be sealed, thereby sealing the excess adhesive in the adhesive applicator 7 and preventing adhesive from overflowing from the end of the round tube.

[0019] Furthermore, a sealing cavity is provided inside the cylinder base 3, and a sealing ring 4 is provided inside the sealing cavity. The sealing ring 4 is located outside the telescopic rod 6, and a sealing pressure plate 2 is provided at one end of the cylinder base 3, with the pressing end of the sealing pressure plate 2 located inside the sealing cavity.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
