Description

Technical Field

[0001] This utility model relates to the field of double-conducting copper foil tape technology, and in particular to a double-conducting copper foil tape with good adhesion performance. Background Technology

[0002] Double-conductive copper foil tape is a type of tape with two conductive copper foil layers, usually containing an adhesive or protective film. This tape is conductive and is mainly used in the electronics industry. It can be used as the grounding conductive part of the anti-static system in computer rooms, ensuring that static electricity can be effectively guided to the ground through the highly conductive copper foil layers, avoiding damage to equipment and personnel.

[0003] Chinese patent discloses a double-sided conductive copper foil tape (authorization announcement number CN215101225U). This patented technology includes a copper foil tape with an inner wheel on its inner side, an outer circular edge on one side of the inner wheel, a tape head on one side of the tape, and a serrated edge on one side of the tape head. A tear-resistant protective film is located at the top of the inner side of the copper foil tape, a first release paper layer is located at the bottom of the tear-resistant protective film, a first conductive adhesive layer is located at the bottom of the first release paper layer, a copper foil layer is located at the bottom of the first conductive adhesive layer, a second conductive adhesive layer is located at the bottom of the copper foil layer, and a second release paper layer is located at the bottom of the second conductive adhesive layer. This double-sided conductive copper foil tape, through its inner wheel and outer circular edge, provides convenient wrapping points; the serrated edge facilitates easy opening; the tear-resistant protective film prevents easy tearing during use; and the easy-tear lines allow for segmentation and easy tearing at desired points, making it easy to use.

[0004] This patented technology has the advantage of being easy to tear and break during use, but it still has shortcomings in the process of use. Because it needs to be adhered to the ground, if the ground is not cleaned properly, dust or particles will remain, which will reduce the adhesion between the double-conducting copper foil tape and the ground. This can easily lead to bumps, bubbles or gaps between the adhesive layer and the ground, reducing the antistatic effect and EMI shielding performance of the double-conducting copper foil tape. Therefore, those skilled in the art have provided a double-conducting copper foil tape with good adhesion performance to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a double-guided copper foil tape with good adhesion performance, including a main structure, including a shell, an installation shaft rotatably installed inside the shell, a roll sleeved on the outside of the installation shaft, a double-guided copper foil tape wound on the outer wall of the roll, the double-guided copper foil tape having a copper foil layer, an adhesive layer and a release paper arranged longitudinally, and a shell cover located at one end of the shell.

[0007] The adhesive structure includes a miniature fan and a battery located at one end of the housing and electrically connected, an installation tube connected to the output end of the miniature fan, and a nozzle connected to the installation tube and installed at an angle downwards.

[0008] The installation structure includes a bearing bracket two fixed at one end of the housing, a pressure roller rotatably installed inside the bearing bracket two, and a material inlet at one end of the housing.

[0009] Furthermore, one end of the housing is provided with symmetrically distributed bearing brackets, a rotating shaft is rotatably mounted inside the bearing brackets, and a connecting block is provided on the outer wall of the rotating shaft to connect with the outer wall of the housing.

[0010] Specifically, the bearing bracket has a pair of rotating shafts that rotate the bearings. When the shafts rotate, they drive the housing cover to move through the connecting block.

[0011] Furthermore, symmetrically distributed torsion springs are sleeved on the outer side of the rotating shaft, and the two ends of the torsion springs are respectively connected to the bearing bracket and the outer wall of the rotating shaft;

[0012] Specifically, when the shaft rotates, torsional elasticity is applied to the torsion spring, thereby providing elastic support to the casing and maintaining elastic positioning after the opening at one end of the casing is closed.

[0013] Furthermore, the front end of the casing is provided with an outer shell, one end of the outer shell is provided with a stroke groove, a cutter is provided inside the outer shell, and one end of the cutter is provided with a pull handle that is slidably installed inside the stroke groove;

[0014] Specifically, the cutter is housed in the outer casing to prevent injury to the user, and a push-pull force is applied to the cutter by moving the handle inside the stroke groove.

[0015] Furthermore, a fixing block is provided on the outer wall of the outer casing, and a spring connected to the fixing block is provided at one end of the pull handle;

[0016] Specifically, the fixing block provides elastic support for the first spring, allowing the cutter located inside the housing to be elastically positioned through the connection between the handle and the first spring.

[0017] Furthermore, a limiting roller located on one side of the material inlet is rotatably installed on the inner wall of the housing, and an installation frame is provided inside the lower end of the material inlet, and a tensioning roller is rotatably installed inside the installation frame;

[0018] Specifically, the limiting roller presses the upper end of the double-guide copper foil tape extending from the feed port, and the tensioning roller supports the lower end of the double-guide copper foil tape passing through the feed port.

[0019] Furthermore, the lower end of the mounting frame is provided with a second spring that is connected to the inner wall of the lower end of the material outlet. The second spring is provided with a slidably inserted positioning rod and a positioning cylinder. One end of the positioning rod is connected to the mounting frame, and one end of the positioning cylinder is connected to the inner wall of the lower end of the material outlet.

[0020] Specifically, when the tension roller supports the lower end of the double-guide copper foil tape, the lower end of the double-guide copper foil tape is elastically supported by spring two. When spring two extends or retracts, it slides inside the positioning cylinder through the positioning rod to limit spring two and ensure the stable lifting and lowering of the tension roller.

[0021] Beneficial effects:

[0022] Compared with existing technologies, the advantages of this utility model are:

[0023] In this invention, the double-guided copper foil tape is installed inside the housing by rotating the drum. During the process of the double-guided copper foil tape adhering to the ground, the double-guided copper foil tape is rolled by the rotating pressure roller, which improves the adhesion between the double-guided copper foil tape and the ground.

[0024] Meanwhile, the airflow delivered by the fan is conveyed through the installation pipe and nozzle. The jet airflow acts on the ground to be bonded with the double-guided copper foil tape, which can effectively remove tiny particles, dust and debris from the ground, ensuring that the ground surface is thoroughly clean. This is beneficial to the adhesion of the material during the bonding process and avoids the formation of air bubbles, gaps or foreign objects during the bonding process, which would affect the adhesion between the adhesive layer and the ground. This ensures the anti-static effect and EMI shielding performance of the double-guided copper foil tape. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] Please see Figures 1-6As shown, this embodiment is a double-conductor copper foil tape with good adhesion performance, comprising:

[0042] The main structure 100 includes a housing 101, a mounting shaft 107 rotatably installed inside the housing 101, a roll 108 sleeved on the outside of the mounting shaft 107, a double-guided copper foil tape 109 wound on the outer wall of the roll 108, the double-guided copper foil tape 109 having a copper foil layer 110, an adhesive layer 111 and a release paper 112 arranged longitudinally in sequence, and a cover 102 located at one end of the housing 101.

[0043] The applicator structure 300 includes a miniature fan 301 and a battery 302 located at one end of the housing 101 and electrically connected, an installation tube 303 connected to the output end of the miniature fan 301, and a nozzle 304 connected to the installation tube 303 and installed at an angle downwards.

[0044] One end of the housing 101 is provided with symmetrically distributed bearing brackets 105. A rotating shaft 104 is rotatably installed inside the bearing brackets 105. A connecting block 103 is provided on the outer wall of the rotating shaft 104 to connect with the outer wall of the housing 102.

[0045] Symmetrically distributed torsion springs 106 are sleeved on the outer side of the rotating shaft 104, and the two ends of the torsion springs 106 are connected to the bearing bracket 105 and the outer wall of the rotating shaft 104, respectively.

[0046] Use of the main structure 100;

[0047] The double-guided copper foil tape 109 is wound up by a sleeve. During the laying process on the ground, the sleeve of the wound double-guided copper foil tape 109 is sleeved on the outside of the mounting shaft 107. One end of the double-guided copper foil tape 109 extends to the outside through the feed port 202. The release paper 112 attached to the adhesive layer 111 is peeled off. First, the ground is cleaned. The ground size is measured according to actual needs, and the laying position of the double-guided copper foil tape 109 is planned. The release paper 112 in the tape is peeled off step by step to expose the adhesive layer 111. The adhesive layer 111 is adhered to the laying position on the ground.

[0048] The micro fan 301 operates, delivering airflow into the installation pipe 303 and spraying it onto the ground to be laid through nozzles 304. The airflow effectively removes tiny particles, dust, and debris from the ground, ensuring a thoroughly clean surface. This airflow cleaning method does not require contact with the ground, avoiding damage or contamination caused by direct physical contact and maintaining the original state of the ground. The cleaned ground is flat and free of impurities, which increases the contact area between the adhesive layer 111 and the ground, improving the adhesion performance of the double-guided copper foil tape 109 adhesive layer 111. Since the computer room environment may have high temperatures, the selected adhesive needs to have high-temperature resistance to ensure that it can maintain adhesion under various working conditions. The adhesive layer 111 is an acrylic series adhesive, which can enhance the adhesion performance of the double-guided copper foil tape 109 and ensure its long-term stable use in the computer room anti-static system.

The tension roller 211 does not directly contact the cross, but directly contacts the release paper 112. The release paper 112 is pulled on one side of the tension roller 211 and then separated from the adhesive layer 111. The user grasps the shell 101 and the cover 102. The shell 101 is adhered to the ground directly below and the adhesive layer 111. The double-guided copper foil tape 109 on the ground is triangular in shape. The bonded double-guided copper foil tape 109 is rolled and pressed by the pressure roller 201 to improve the adhesion of the adhesive layer 111. After the double-guided copper foil tape 109 is laid to the designated position, the pull handle 209 is pulled down to cut the double-guided copper foil tape 109. After use, the cutter 206 is stored in the housing by the elastic force of the spring 208 to protect the cutter 206 and the user and prevent accidental hand contact with the cutter 206 during use.
