Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing technology, and in particular to a flexible half clamp for applying adhesive to heat shrink tubing. Background Technology

[0002] For corrosion protection of gas transmission steel-plastic conversion joints, heat shrink sleeves are used. Currently, a clamping mechanism is generally used to clamp the end of the round pipe, as shown in the existing patent 202021847569.9. However, the disadvantage of this mechanism is that the expansion claw needs to be inserted axially when the round pipe is placed, and it also needs to be moved out axially when the part is removed, which makes the operation inconvenient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flexible half clamp for coating heat shrink tubes.

[0004] The purpose of this utility model is achieved through the following technical solution: a flexible half clamp for applying adhesive to heat shrink tubing, comprising an inner groove, on which a plurality of mounting grooves are provided, a silicone strip is installed in the mounting groove, and the end of the silicone strip protrudes from the mounting groove, the inner groove is located on the outside of the round tube, and a pressure ring is installed on the outer surface of the inner groove by locking bolts, the pressure ring is provided with mounting holes, and the locking bolts are located on both sides of the mounting holes.

[0005] Preferably, there are two inner grooves.

[0006] Preferably, both pressure rings are installed on the placement plate and the pressure plate respectively by locking bolts b, and the pressure plate is connected to the piston rod of the cylinder. The cylinder and the placement plate are both installed on the mounting frame. The mounting frame is slidably set on the worktable, and an adhesive applicator is provided on one side of the worktable.

[0007] This utility model has the following advantages: By placing one end of the round tube in the inner groove of the placement plate, and then using a cylinder to drive the inner groove above the round tube to move downward, the silicone strip is brought into contact with the outer surface of the round tube to generate friction, thereby moving the round tube to complete the gluing process. This avoids the need for the round tube to be inserted into the expanding claw to clamp it, thus improving the convenience of operation. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] In this embodiment, as Figure 1 and Figure 2 As shown, a flexible half-clamp for applying adhesive to heat shrink tubing includes an inner groove 1, preferably two inner grooves 1. Several mounting grooves 3 are formed on the inner groove 1, and silicone strips 4 are mounted on the mounting grooves 3, with the ends of the silicone strips 4 protruding from the mounting grooves 3. The inner groove 1 is located outside the round tube 14. A pressure ring 2 is mounted on the outer surface of the inner groove 1 via locking bolts 5. Mounting holes 6 are formed on the pressure ring 2, and the locking bolts 5 are located on both sides of the mounting holes 6. By placing one end of the round tube 14 into the inner groove 1 on the placement plate 22, and then moving the inner groove 1 above the round tube 14 downwards via a cylinder 19, the silicone strips 4 adhere to the outer surface of the round tube 14, generating friction. This causes the round tube 14 to move and complete the adhesive application, avoiding the need for the round tube 14 to be inserted into the expanding claw for clamping, thus improving the ease of operation.

[0019] Furthermore, such as Figure 3As shown, both pressure rings 2 are installed on the placement plate 22 and pressure plate 20 respectively by locking bolts b21, and the pressure plate 20 is connected to the piston rod of the cylinder 19. The cylinder 19 and the placement plate 22 are both installed on the mounting frame 18. The mounting frame 18 is slidably mounted on the worktable 16, and a glue applicator 7 is provided on one side of the worktable 16. Specifically, a placement rack a12 is also provided on the workbench 16, and a baffle 17 is provided on one side of the placement plate 22. The baffle 17 is also installed on the mounting rack 18. The operator first installs the two inner tanks 1 on the placement plate 22 and the pressure plate 20 respectively by locking bolts b21. Then, the two ends of the round tube 14 to be coated are placed on the lower inner tank 1 and the placement rack a12 respectively, and the ends of the round tube 14 are made to contact the baffle 17. Then, the cylinder 19 is activated to drive the upper inner tank 1 to move down, so that the silicone strip 4 is attached to the outer surface of the round tube 14 to generate friction. Then, the mounting rack 18 is moved along the workbench 16 so that the round tube 14 is fitted on the outside of the coating mechanism 7, waiting for the coating. In this embodiment, the glue application mechanism 7 and the movable mounting bracket 18 along the worktable 16 are existing structures and have not been modified. The specific structure is as follows: The glue application mechanism 7 includes a glue pump 8, a glue application rod 9, and a glue application head 10. That is, the glue pump 8 and the glue application head 10 are respectively installed at both ends of the glue application rod 9. The glue pump 8 is then connected to an external glue tank (not shown in the figure). The worktable 16 is provided with a ball screw 13 and a slide rail. The ball screw 13 is driven by an existing motor (not shown in the figure). A slider 15 is threaded on the ball screw 13. The two ends of the slider 15 are slidably installed on the slide rail, and the mounting bracket 18 is installed on the upper surface of the slider 15. That is, the motor drives the ball screw 13 to rotate forward and backward, thereby driving the slider 15 to reciprocate along the slide rail, thereby making the round tube 14 move synchronously. In other words, after the silicone strip 4 is attached to the outer surface of the round tube 14, the motor drives the ball screw 13 to rotate, thereby causing the slider 15 to move closer to the glue applicator 10, so that the round tube 14 is fitted over the glue applicator 9. After it moves into place, the glue pump 8 starts, and the glue in the glue tank overflows sequentially through the glue applicator 9 and the glue applicator 10, thereby applying glue to the inner wall of the round tube 14. During the glue application process, the motor drives the ball screw 13 to rotate in the opposite direction, thereby causing the slider 15 to move away from the glue applicator 10. Due to the friction generated by the attachment of the silicone strip 4 to the outer surface of the round tube 14, the round tube 14 will move synchronously, reducing the overlapping area between the round tube 14 and the glue applicator 9, thus completing the glue application.

[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.
