Description

Technical Field

[0001] This invention relates to the field of adhesive tape protection technology, specifically a process for applying adhesive tape to protect the welding surface. Background Technology

[0002] Spot welding tape is a synthetic rubber series based on EPDM, used to wrap and protect the welding area to prevent damage.

[0003] For example, the Chinese authorized patent CN113372830A (A Weldable Structural Tape and Its Preparation Method) includes 40-60% epoxy resin, 5-10% modified epoxy, 3-8% toughening agent, 2-8% solid rubber, 10-30% inorganic filler, 0.1-2% thixotropic agent, 1-5% multifunctional epoxy resin, 0.1-0.3% silane coupling agent, 1-5% carbon black, 1-10% curing agent, and 0.5-5% accelerator. This invention uses epoxy resin as the matrix and combines it with solid rubber to produce a tape with high adhesion, exhibiting good adhesion to steel plates coated with anti-rust oil. The addition of an appropriate amount of carbon black, a welding aid, ensures the colloid's conductivity does not affect welding. The various raw materials in the formula work together to allow the tape disclosed in this invention to be directly cured at high temperatures onto cold-rolled steel plates, with a foaming ratio not exceeding 50%, providing effective sealing and bonding without affecting welding.

[0004] However, when applying tape to protect the welding surface, most existing methods involve cutting the tape to the correct size before application, which easily leaves fingerprints on the bottom surface, resulting in poor adhesion and gaps or overlaps, leading to uneven adhesion. Therefore, this method does not meet the current requirements. To address this, we propose a new process for protecting the welding surface with tape. Summary of the Invention

[0005] The purpose of this invention is to provide a process for protecting the welded surface with tape, in order to solve the problems mentioned in the background art. In most cases, when applying tape to protect the welded surface, the tape is first cut to the correct size before being applied, which easily leaves fingerprints on the bottom surface, resulting in poor adhesion and gaps or overlaps, leading to uneven adhesion.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a process for protecting a welding surface with adhesive tape, comprising: a welding plate, wherein a welding surface is provided on the upper surface of the welding plate, and the welding surface is welded to the welding plate to form a welded surface;

[0007] Also includes:

[0008] A first-layer welding tape is disposed at the upper end of the welding surface, and the lower surface of the first-layer welding tape is adhesively connected to both the welding plate and the welding surface.

[0009] The double welding tape is disposed above the first welding tape, and half of the lower surface of the double welding tape is adhesively connected to the upper surface of the first welding tape, while the other half of the lower surface of the double welding tape is adhesively connected to the upper surface of the welding plate.

[0010] Preferably, the center of the double welding tape is a through-cavity.

[0011] Preferably, the process of applying adhesive tape to protect the welding surface includes the following steps:

[0012] Step 1: Wrap the produced welding tape around the outside of the tape take-up seat. When using it, take the exposed end and peel off the release paper located on the bottom of the welding tape.

[0013] Step 2: Attach the peeled-off side of the release paper to the welding plate on one side of the welding surface, and then pull it to the other side of the welding surface to ensure that the welding tape is flat and does not bend.

[0014] Step 3: Then press down on the welding tape, and tear the release paper back as far as possible before pressing down, until the welding tape is attached to the welding plate. Then use the blade on the tape take-up unit to cut the welding tape, and use the ball bearing to roll the upper surface and edges of the welding tape.

[0015] Step 4: Apply the welding tape with a through-cavity center onto the already fixed welding tape, with half of the welding tape with a through-cavity center in contact with the upper surface of the already fixed welding tape and the other half in contact with the welding plate.

[0016] The tape take-up holder includes a tape take-up ring, the inside of which is provided with a through groove, and the single-welded tape is wound around the outside of the tape take-up ring.

[0017] Preferably, a limiting round seat is provided inside the through groove, a bearing sleeve is provided inside the limiting round seat, a ball bearing is provided inside the bearing sleeve, and the outer wall of the ball bearing is tightly connected to the inner wall of the bearing sleeve. A movable column is provided inside the ball bearing, and the movable column is rotatably connected to the bearing sleeve through the ball bearing.

[0018] Preferably, the outer wall of the bearing sleeve is provided with a limiting moving block, and the limiting moving block and the bearing sleeve are an integral structure. The inner wall of the limiting round seat is provided with a limiting moving groove, and the limiting moving groove and the limiting round seat are an integral structure. The limiting moving block moves along the limiting moving groove.

[0019] Preferably, a connecting arm is provided on one side of the movable column, and the connecting arm and the movable column are integrally formed. A blade mounting bracket is provided on the outside of one end of the connecting arm. A blade is provided on one side of the blade mounting bracket. A round iron sheet is welded to one end of the blade. A magnet is provided at one end of the round iron sheet.

[0020] Preferably, the other end of the blade mounting bracket is provided with a rotating bearing, and the blade mounting bracket is welded to the rotating bearing. One end of the rotating bearing is provided with a connecting seat, and the connecting seat is welded to the connecting arm. The rotating bearing is rotatably connected to the connecting arm through the connecting seat.

[0021] Preferably, one end surface of the movable column is provided with a ball groove, and the ball groove and the movable column are integral structures. A ball is embedded inside the ball groove and rotates along the ball groove. The other end of the movable column is provided with a limit baffle, and the limit baffle and the movable column are integral structures.

[0022] Preferably, the outer walls of the limiting round seat are provided with elastic ropes, one end of which is wound and connected to the outer wall of the limiting round seat. One end of the elastic rope is provided with a fixed lifting ring. The fixed lifting ring has a lifting ring groove inside, and the lifting ring groove passes through the fixed lifting ring. One side surface of the fixed lifting ring is provided with a lifting ring threaded post, and the lifting ring threaded post is welded to the fixed lifting ring. The inner wall of the through groove is provided with a threaded connection groove, and the threaded connection groove and the tape winding ring are integral structures. The lifting ring threaded post is threadedly connected to the threaded connection groove.

[0023] Preferably, the front surface of the tape take-up coil is provided with a protective groove, and the protective groove and the tape take-up coil are an integral structure.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention involves attaching one side of the release paper to the welding plate on one side of the welding surface, and then pulling it to the other side of the welding surface. This ensures that the welding tape is flat and does not bend, and adheres to the welding surface. Thus, a first layer of welding tape is applied to the upper part of the welding surface, and a second layer of welding tape is applied above the first layer. The center of the second layer of welding tape has a through-cavity. Half of the lower surface of the second layer of welding tape is adhesively connected to the upper surface of the first layer of welding tape, and the other half of the lower surface of the second layer of welding tape is adhesively connected to the upper surface of the welding plate. The first layer of welding tape protects the welding surface, and the second layer of welding tape further protects the edges of the first layer, thereby preventing water ingress, improving the protective effect, and reducing the likelihood of the first layer of welding tape curling at the edges.

[0026] 2. By setting a limiting round seat inside the through groove of the tape take-up coil, and installing a bearing sleeve with ball bearings inside the limiting round seat, the moving column rotates through the ball bearing and the bearing sleeve. One end of the moving column is a connecting arm that fixes the blade. When it is necessary to cut the welded tape, the bearing sleeve moves back and forth along the limiting round seat, and is limited by the limiting baffle to prevent the bearing sleeve from falling off. The direction of the moving column is adjusted by the ball bearing, which also realizes the adjustment of the blade angle. The blade rotates by the rotating bearing and the connecting arm, and the angle is further adjusted, thus facilitating the cutting operation of the welded tape. This eliminates the need for external scissors. The integrated design is simple and convenient, preventing the welding tape from loosening and folding due to the lack of scissors. It improves the flatness of the fixation. When moving the limiting cylinder, it is fixed by four elastic cords. The pulling force during movement facilitates the cutting of the welding tape at different positions, improving flexibility and making it easy to quickly return to the initial position without falling off. After cutting, the roller at one end of the moving column is used to roll and compact the welding tape. The cutting and compaction steps are all done on the tape rewind loop, improving functionality and reducing the number of adhesive tools required, thus improving portability.

[0027] 3. By setting a protective groove on the front surface of the tape winding coil, setting a magnet on the bottom of the protective groove, and setting a round iron plate at one end of the blade mounting bracket, the blade mounting bracket is inserted into the protective groove, which protects the blade, prevents damage to the blade, and prevents injury, thus improving safety. The magnetic fixing method between the round iron plate and the magnet prevents the blade mounting bracket from automatically slipping out, improving the convenience of fixing.
