Description

Technical Field

[0001] The utility model belongs to the technical field of heat shrink sleeves, and in particular relates to a device structure for pasting a plastic film inside a heat shrink tube. Background Art

[0002] The heat shrink sleeve generally needs to be a structure of a base layer plus an internal composite adhesive layer. When heated and installed, the base layer shrinks radially while the internal composite adhesive layer melts and tightly wraps around the patch. Together with the base layer, it forms a solid anti-corrosion body outside the pipe, which has excellent wear resistance, corrosion resistance, impact resistance, and good resistance to ultraviolet and light aging. The inside of the heat shrink sleeve is a composite adhesive layer. There is an internal glue coating operation during manufacturing. The traditional method is to heat the glue liquid at high temperature and melt it before coating. At this time, the internally coated glue liquid is in liquid state. Artificial coating has problems such as high temperature and generation of harmful gases. In addition, it is not easy to control the thickness of the glue liquid during coating. The thickness of the glue liquid coated once is relatively thin, and multiple coatings are required. This will affect the life safety and health of production personnel for a long time. Therefore, the improved process adopts the method of pasting the adhesive layer to form a composite adhesive layer. After heating the base layer of the heat shrink sleeve, it is pasted together with the heated adhesive layer. Therefore, it is necessary to design a constant temperature heating and expansion device to achieve the internal adhesive film of the heat shrink tube. Utility Model Content

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0024] Example:

[0025] like Figure 1-Figure 3 As shown, a device structure for pasting a film inside a heat shrink tube. It includes a fixed constant temperature pressure tube 1, a lifting constant temperature pressure tube 2 and a movable pressure tube 3. The fixed constant temperature pressure tube 1, the lifting constant temperature pressure tube 2 and the movable pressure tube 3 are arranged in parallel and form a triangular layout. The triangular layout can well support the base layer, and at the same time, it can leave a large space inside the base layer to facilitate personnel operation. The front end position of the fixed constant temperature pressure tube 1 is kept fixed and a support structure 4 for easy rotation is arranged at the end. The fixed constant temperature pressure tube 1 is connected to a rotating motor 6; one end of the lifting constant temperature pressure tube 2 is installed on the lifting mechanism and the other end is installed on the lifting support structure 5; both ends of the movable pressure tube 3 are movably installed on the movable mechanism In the groove 801 of the moving part 8, a roller 10 is arranged in the groove 801 for easy rotation. Of course, this is only a more suitable method. Its main purpose is to fix the constant temperature pressure tube 1 and the lifting constant temperature pressure tube 2 on the head 7 by fixing the front end. The head 7 itself can rotate to a certain extent to separate from the support structure 4 at the end to facilitate the installation of the base layer. The base layer generally relies on workers to lift the two ends of the moving pressure tube 3 and lift the base layer together to pass the base layer through the fixed constant temperature pressure tube 1 and the lifting constant temperature pressure tube 2, and then pass the moving pressure tube 3 through the base layer and place it in the groove 801 of the moving part 8, so as to realize the initial installation of three constant temperature pressure tubes passing through the base layer.

[0026] The fixed constant temperature pressure tube 1 and the lifting constant temperature pressure tube 2 both adopt constant pressure tubes. The length of the pressure tube can be set to a corresponding length according to needs. The mobile pressure tube 3 is selectively used. Generally speaking, the mobile pressure tube 3 is shorter for easy lifting. The constant temperature pressure tube includes a rotating joint, an inner water inlet tube, and a pressure tube. The rotating joint is provided with a water inlet, which is connected to the front end of the inner water inlet tube. The inner water inlet tube is sleeved in the pressure tube. The front end of the pressure tube is connected to the rotating body of the rotating joint so that the pressure tube can rotate relative to the rotating joint. The outer surface of the pressure tube is covered with an anti-sticking layer, and the rear end of the pressure tube is closed. In this scheme, the fixed constant temperature pressure tube 1 is connected to a motor to realize active rotation, and the lifting constant temperature pressure tube 2 adopts passive rotation. The rotating joint connects the water supply pipe and the water outlet pipe. The water in the water supply pipe is constant temperature water, and the rotating joint facilitates the rotation of the pressure tube.

[0027] The fixed thermostatic pressure tube 1 and the lifting thermostatic pressure tube 2 are installed on the same machine head 7, and the lower end of the machine head 7 is rotatably installed on the table 9. The fixed thermostatic pressure tube 1 is rotatably installed at the front end through the mounting seat, and the guide rod 702 and the screw rod 701 are installed at the upper end of the mounting seat. The slider 703 is installed on the guide rod 702 and the screw rod 701. The slider 703 is engaged with the screw rod 701 and is driven to rise and fall by the rotation of the screw rod 701. The front end of the lifting thermostatic pressure tube 2 is rotatably installed on the slider 703. Of course, this is only a relatively simple machine head 7 structure that can be realized, and other structures can be used to realize it. The main purpose is to realize the fixing and active rotation of the fixed thermostatic pressure tube 1 and the lifting and lowering of the lifting thermostatic pressure tube 2. At the same time, there must be a support structure 4 at both ends of the fixed thermostatic pressure tube 1 and the lifting thermostatic pressure tube 2 to avoid the instability and sagging of the thermostatic pressure tube rotation, and the end of the lifting thermostatic pressure tube 2 must be able to maintain the ability to not sag after being separated from the support at the end.

[0028] The rotating motor 6 is mounted on the housing of the machine head 7, and the rotating shaft of the rotating motor 6 is connected to the front end of the fixed constant temperature pressure tube 1 through a pulley. The motor is only used to drive the mobile pressure tube 3 to rotate, and its structure can be diverse.

[0029] The support structure 4 of the fixed constant temperature pressure tube 1 and the lifting support structure 5 of the lifting constant temperature pressure tube 2 are arranged on the same support column. A support mechanism for receiving the fixed constant temperature pressure tube 1 is arranged at a corresponding height at the lower end of the support column, and the lifting support structure 5 is installed at the upper end of the support column. The lifting support structure 5 is actually a structure that relies on manual lifting. The lifting constant temperature pressure tube 2 is fixed in height during the production process for products of the same specification, and the base layer can be tightened by moving the pressure tube 3.

[0030] The support mechanism and the mobile support mechanism are side groove structures, and rollers 10 arranged up and down are provided in the grooves. When the head 7 rotates, the fixed constant temperature pressure tube 1 and the lifting constant temperature pressure tube 2 are separated from or enter the support mechanism and the mobile support mechanism. The roller 10 is mainly used to support the pressure tube after the base layer is tightened. The roller 10 can be implemented in the form of a wheel or a bearing, and its specific installation position can be installed according to the force trend of the pressure tube after tightening.

[0031] The moving mechanism is installed at the bottom of the table 9, and parallel grooves are opened on both sides of the table 9. The moving parts 8 of the moving mechanism are installed in the grooves accordingly, that is, the main body of the moving mechanism is arranged at the bottom of the table 9, and the moving parts 8 on both sides keep the same movement.

[0032] The movable part 8 is a thin sheet with a groove on the top of the sheet. The groove is arranged in an arc shape on the side away from the fixed constant temperature pressure tube 1 and the arc shape faces the fixed constant temperature pressure tube 1. A roller 10 is arranged on the side of the groove arc, and the upper groove facilitates the placement of the movable pressure tube 3.

[0033] There are two rollers 10, and the movable pressing tube 3 is located in the depression between the two rollers 10. A groove is formed between the two rollers 10, so it is convenient to place the pressing tube.

[0034] The fixed constant temperature pressure pipe 1 and the lifting constant temperature pressure pipe 2 are located in the same vertical plane, which can facilitate the installation of the base layer.
