Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a tool for peeling off the adhesive layer of a steel strip reinforced polyethylene (PE) spiral corrugated pipe. Background Technology

[0002] Steel-reinforced polyethylene (PE) spiral corrugated pipe is a double-walled spiral corrugated pipe with high-density polyethylene (PE) as the base material, steel strips coated with adhesive resin forming a waveform as the main support structure, and polyethylene material wound and compounded together to form a whole.

[0003] After the steel-reinforced polyethylene (PE) spiral corrugated pipe is produced, it is necessary to sample and test the peel strength of the polyethylene adhesive layer on the outside of the steel strip. The traditional testing method is to use a utility knife to cut open the corrugated pipe sample at the crest and lift up a strip of adhesive. Then, a force gauge is used to clamp the movable end of the adhesive strip, and force is applied to drag the movable end of the adhesive strip and tear it away from the steel strip layer to perform the peel strength test.

[0004] The wider the adhesive strip that is cut and lifted, the larger the contact area between the strip and the steel strip, and the greater the peeling force required. Therefore, when cutting the adhesive layer, workers need to use a ruler to measure the required width of the lifted adhesive strip at the crest of each corrugated pipe sample and mark it before using a utility knife to cut and lift the strip, ensuring that the measured width is consistent. However, in mass production, a large number of samples need to be inspected, and this method of measuring and marking each sample individually presents a problem of high labor intensity. Utility Model Content

[0005] In view of the above problems, this utility model provides a peeling tool for the adhesive layer of steel strip reinforced polyethylene (PE) spiral corrugated pipe.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A peeling tool for steel-reinforced polyethylene (PE) spiral corrugated pipe is provided, comprising a mounting frame. Two parallel first tool holders are horizontally slidably mounted on the mounting frame, each holding a first blade. A second tool holder is vertically slidably mounted on one side of the two first tool holders, holding a second blade perpendicular to the first blades. The mounting frame includes a first driving member for moving the two first tool holders to adjust the distance between the two first blades, and a second driving member for moving the second tool holder.

[0008] Furthermore, the first driving component includes a bidirectional screw, which is parallel to the direction of movement of the first tool holder and rotatably mounted on the mounting bracket. The two first tool holders are respectively threaded onto the two threaded sections of the bidirectional screw, and a first handle is connected to one end of the bidirectional screw.

[0009] Furthermore, one side of the mounting bracket is provided with a scale line for marking the distance between the two first blades, and each of the two first blade holders is provided with a pointer.

[0010] Furthermore, connecting components are provided between the first blade and the first tool holder, and between the second blade and the second tool holder. The connecting components include a limiting pin. The first tool holder and the second tool holder are respectively provided with mounting grooves for accommodating the first blade and the second blade. First through holes are provided through both sides of the mounting grooves. Second through holes are provided through both the first blade and the second blade. A stop block is integrally fixed to one end of the limiting pin. An abutment block is linearly slidably provided on the outer wall of the limiting pin, and the distance between the abutment block and the stop block is adapted to the first tool holder / second tool holder. A sliding groove is provided on the outer wall of the limiting pin for the abutment block to slide, and an elastic element is provided in the sliding groove for driving the abutment block to move out of the sliding groove. After the limiting pin passes through the first through hole and the second through hole, the abutment block and the stop block respectively contact the side walls of the first tool holder / second tool holder.

[0011] Furthermore, the first tool holder / second tool holder is embedded with an electric heating rod for heating the first blade / second blade.

[0012] Furthermore, the mounting bracket is equipped with a handle, and a third through hole is provided on the handle for a person's hand to pass through.

[0013] The beneficial effects of this utility model are as follows: According to the required width of the rubber strip for testing, the operator can adjust the distance between the two first blades through the first drive component, and then cut two slits at the crest of the corrugated pipe through the two first blades. Next, the second blade cuts the rubber strip between the two slits, and then the movable end of the rubber strip is lifted up so that the force gauge can hold it, which has the effect of reducing the labor intensity of the operator.

Detailed Implementation

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a peeling tool for a steel-reinforced polyethylene (PE) spiral corrugated pipe, referring to... Figure 1 , Figure 2 and Figure 3 The device includes a mounting frame 1, on which two parallel first tool holders 2 are horizontally and linearly slidably arranged. Each first tool holder 2 is provided with a first blade 3. A second tool holder 4 is vertically and slidably arranged on one side of the two first tool holders 2 on the mounting frame 1. Each second tool holder 4 is provided with a second blade 5, which is perpendicular to the first blade 3. The mounting frame 1 is provided with a first driving member 6 for driving the two first tool holders 2 to move to adjust the distance between the two first blades 3. The mounting frame 1 is also provided with a second driving member 7 for driving the second tool holder 4 to move.

[0021] In this embodiment, based on the required adhesive strip width for testing, the operator can adjust the distance between the two first blades 3 using the first drive unit 6. Then, the two first blades 3 cut two slits at the crest of the corrugated pipe. Next, the second blade 5 cuts the adhesive strip between the two slits, and then the movable end of the adhesive strip is lifted for clamping by the force gauge. The height of the second blade 5 can be adjusted using the second drive unit 7 to prevent the second blade 3 from scraping the adhesive layer when cutting the slits. This adhesive strip peeling tool for steel-reinforced polyethylene (PE) spiral corrugated pipe requires only a single adjustment of the distance between the two first blades 3 to peel the adhesive strip from multiple samples, effectively reducing the labor intensity of the operator.

[0022] Specifically, the first driving component 6 includes a bidirectional screw 61, which is parallel to the direction of movement of the first tool holder 2 and is rotatably mounted on the mounting bracket 1. The two first tool holders 2 are respectively threadedly connected to the two threaded sections of the bidirectional screw 61, and a first handle 62 is welded to one end of the bidirectional screw 61.

[0023] In this embodiment, rotating the bidirectional screw 61 can drive the two first cutter holders 2 to move in opposite directions and adjust the distance between the two first blades 3 so that they can cut out strips of corresponding width.

[0024] The second driving component 7 includes a screw, which is parallel to the moving direction of the second tool holder 4 and threaded onto the mounting bracket 1. One end of the screw is rotatably connected to the second tool holder 4, and the other end of the screw is welded to a second handle. A guide rod parallel to the screw is also welded onto the second tool holder 4, and the guide rod moves through the mounting bracket 1. Rotating the screw drives the second tool holder 4 to move, thereby adjusting the height of the second blade 5.

[0025] To facilitate the adjustment of the distance between the two first blades 3 by the staff, a scale line 8 for marking the distance between the two first blades 3 is provided on one side of the mounting bracket 1, and a pointer 9 is welded on each of the two first blade holders 2.

[0026] Reference Figure 4 Connectors are provided between the first blade 3 and the first tool holder 2, and between the second blade 5 and the second tool holder 4. Each connector includes a limiting pin 10. The first tool holder 2 and the second tool holder 4 are respectively provided with mounting grooves for accommodating the first blade 3 and the second blade 5. First through holes 40 are provided through both sides of the mounting grooves, and second through holes are provided through the first blade 3 and the second blade 5. A stop block 101 is integrally fixed to one end of the limiting pin 10. An abutment block 102 is linearly slidably provided on the outer wall of the limiting pin 10, and the distance between the abutment block 102 and the stop block 101 is adapted to the first tool holder 2 / second tool holder 4. A sliding groove 103 is provided on the outer wall of the limiting pin 10 for the sliding of the abutment block 102, and an elastic element 104 is provided within the sliding groove 103 to drive the abutment block 102 out of the sliding groove 103. After the limiting pin 10 passes through the first through hole 40 and the second through hole, the abutting block 102 and the stop block 101 respectively contact the two side walls of the first tool holder 2 and the second tool holder 4.

[0027] In this embodiment, the elastic element 104 is a spring, with its two ends abutting against the abutment block 102 and the inner bottom wall of the slide groove 103, respectively. After the first blade 3 / second blade 5 is inserted into the mounting groove, the operator can pass the limiting pin 10 through the first through hole 40 and the second through hole. Under the elastic force of the spring, the abutment block 102 moves out of the slide groove 103 and contacts the side walls of the first blade holder 2 / second blade holder 4 with the stop block 101, thus preventing the limiting pin 10 from disengaging from the first blade holder 2 / second blade holder 4. When disassembling the first blade 3 / second blade 5, the operator only needs to apply force to press the abutment block 102 back into the slide groove 103 to pull out the limiting pin 10. This specifically improves the ease of disassembly and assembly of the first blade 3 / second blade 5.

[0028] To facilitate the cutting of the rubber layer of the corrugated pipe, the first cutter holder 2 / second cutter holder 4 is equipped with an electric heating rod 20 for heating the first blade 3 / second blade 5.

[0029] In this embodiment, activating the electric heating rod 20 can heat the first blade holder 2 / second blade holder 4 and conduct heat to the first blade 3 / second blade 5, which improves the ease of cutting the adhesive layer.

[0030] Furthermore, the mounting bracket 1 is provided with a handle 30, and a third through hole 301 for a person's hand to pass through is provided on the handle 30.

[0031] In this embodiment, workers with larger hands can grip the outer wall of the handle 30 to use the knife, while workers with smaller hands can pass their hands through the third through hole 301 to grip the handle 30. Furthermore, this method of gripping the handle 30 by passing the hands through the third through hole 301 also prevents workers with less strength from dropping the knife due to unstable force application.

[0032] The principle of the adhesive stripping tool for steel-reinforced polyethylene (PE) spiral corrugated pipes in this application is as follows: Based on the required adhesive strip width for testing, the operator can adjust the distance between the two first blades 3 using the first drive component 6. Then, the two first blades 3 cut two slits at the crest of the corrugated pipe. Next, the second blade 5 cuts the adhesive strip between the two slits, and then the movable end of the adhesive strip is lifted for clamping by a force gauge. This adhesive stripping tool for steel-reinforced polyethylene (PE) spiral corrugated pipes only requires adjusting the distance between the two first blades 3 once to peel the adhesive strip from multiple samples, thus reducing the labor intensity of the operator.
