Description

Technical Field

[0001] The present invention relates to the field of coil protection, and particularly to a coil protection paper pad and a paper pad stacking device.

Background Art

[0002] After the coil is processed, it needs to be annealed as a finished product. The product is in a soft state after annealing, which is extremely likely to cause defects such as flattened tubes, spraying damage, and scratching. After the coil annealing, the copper packing straps left by the rewinding and finishing process need to be removed, and male and female straps are added. After the copper tubes are stacked, the male and female straps need to be removed. A paper pad is placed at the bottom of the copper tubes to protect the coil. However, when removing the male and female straps, the bottom of the tubes will be rubbed or squeezed, affecting the use of the tubes.

[0003] The prior art discloses some paper pads that can protect tubes. However, when these paper pads are used, it is difficult to accurately place the coil in the designated area.

Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a coil protection paper pad, which solves the problem that it is difficult to accurately place the coil in the designated area when the coil is placed on the protective paper pad.

[0005] To solve the above technical problem, the present invention adopts the following technical solutions:

[0006] The coil protection paper pad includes a circular bottom plate, four through grooves arranged on the bottom plate and extending from the edge of the bottom plate towards the center of the circle. On the upper surface of the bottom plate, there are multiple pairs of positioning components spaced circumferentially along the bottom plate. The positioning components include a first positioning block and a second positioning block. The first positioning block and the second positioning block are arc-shaped structures with the center of the bottom plate as the center of the circle. When the coil is placed on the bottom plate, the coil is located between the first positioning block and the second positioning block, and the straps for bundling the coil are located between the through grooves.

[0007] The whole coil is annular. Therefore, making the bottom plate for carrying the coil circular is sufficient to support the coil, which can save the manufacturing materials of the coil protection paper pad;

[0008] The straps for bundling the coil are located in the through grooves. When placing the coil, the straps will not dig into the coil and cause the surface of the coil to sink. When removing the straps, the straps can also be cut short and then pulled out from the through grooves;

[0009] The first positioning block and the second positioning block can limit the position of the coil placed on the bottom plate, so that the coil is placed as much as possible in the central position of the bottom plate, which is convenient for adjusting the straps into the through grooves without contacting the bottom plate, making the pressure received by the bottom plate more uniform, extending the service life of the bottom plate, and being able to better protect the coil.

[0010] Furthermore, the angle formed by connecting the centers of two adjacent said through slots and the center line of the bottom plate is between 89° and 91°. The intervals between multiple through slots are nearly equal, and the intervals between the straps on the coiled pipe are also nearly equal, which will result in better fixing and packaging effects; the main function of the through slots is to facilitate the extraction of the straps. Therefore, the position of the through slots does not require particularly high precision, and a certain error is allowed, which will be more convenient during processing.

[0011] Furthermore, each group of said positioning components is located between two adjacent through slots. The positioning components are evenly distributed on the surface of the bottom plate, and their positioning effect on the coiled pipe will be better.

[0012] Furthermore, the distance between the two side edges of the through slot is W1, and the width of the strap used for bundling the coiled pipe is W2, and W1 ≥ W2 + 5 cm. Only when the width of the through slot is greater than the width of the strap can the strap be located within the through slot, and the quality of the coiled pipe will not be affected when extracting the strap; if W1 ≥ W2 + 5 cm, a 5 cm gap can be left to facilitate the placement of the coiled pipe.

[0013] Furthermore, multiple pairs of positioning slots adapted to the positioning components are provided on the bottom end face of the bottom plate, and the depth of the positioning slots is greater than the heights of the first positioning block and the second positioning block to achieve the stacking of multiple layers of coiled pipe protection paper pads. The completed coiled pipe protection paper pads need to be stored. However, due to the presence of the positioning components on the upper surface, it is not flat. After setting the positioning slots, the stacking of multiple layers of coiled pipe protection paper pads can be achieved, and after stacking, the cooperation between the positioning components and the positioning slots can limit the relative movement between the coiled pipe protection paper pads, making the overall stacked structure more stable.

[0014] Furthermore, the thickness of the bottom plate is 7 to 10 mm. When the thickness of the bottom plate is less than 7 mm, the protective effect of the coiled pipe protection paper pad on the coiled pipe is not good; when the thickness is greater than 10 mm, it is unnecessary, as the protective ability will not increase, and it will waste too much raw material and increase the production cost.

[0015] Furthermore, the radian of the first positioning block and the second positioning block is between π / 4 and π / 3; or, the sides of the first positioning block and the second positioning block are flush with the sides of the through slot. Multiple pairs of positioning components are arranged at intervals, and there are through slots between two adjacent pairs of positioning components. When placing the coiled pipe on the bottom plate, the strap needs to be aligned with the through slot. After the positioning components are arranged between two adjacent through slots, when placing the coiled pipe, first adjust the coiled pipe to adjust the position of the strap between two adjacent pairs of positioning components. After lowering the coiled pipe a certain distance, make fine adjustments to align the strap with the through slot, and finally complete the placement of the coiled pipe, reducing the contact between the strap and the bottom plate during the placement process, thereby preventing the extrusion or friction of the pipe material.

[0016] If the sides of the first positioning block and the second positioning block are flush with the side of the through groove, the blocking effect of the positioning component will be better. Moreover, during production, two annular bodies can be produced on the surface of the base plate, and the positioning component can be directly produced when cutting the through groove.

[0017] The paper pad stacking device includes a circular base, a star shaft arranged at the central position of the base, and the above-mentioned coiled pipe protection paper pads. A through hole is provided at the central position of the base plate. A plurality of pairs of limit blocks whose shapes are adapted to the positioning grooves are provided on the upper surface of the base. When the multi-layer coiled pipe protection paper pads are stacked on the base, the star shaft passes through a plurality of through holes to radially position the multi-layer coiled pipe protection paper pads, and the limit blocks are inserted into the positioning grooves to limit the rotation of the multi-layer coiled pipe protection paper pads.

[0018] The paper pad stacking device is used to place the stacked multi-layer coiled pipe protection paper pads and facilitate the transportation of the paper pads; the star shaft and the limit blocks can radially position the multi-layer coiled pipe protection paper pads to prevent the coiled pipe protection paper pads from moving on the base, and the limit blocks can also prevent the coiled pipe protection paper pads from rotating, so that the coiled pipe protection paper pads can be stable on the base and will not be scattered during transportation; the circular base is not easy to hurt people during hoisting, and can save materials and reduce production costs.

[0019] Furthermore, the paper pad stacking device further includes a cover plate and a fixing member. The cover plate includes a circular plate body, a first groove provided at the bottom end face of the plate body and adapted to the star shaft, and an insertion hole provided at the upper end face of the plate body and communicating with the first groove. The threaded shaft on the fixing member passes through the insertion hole and is in threaded cooperation with the star shaft to fix the cover plate on the star shaft. The fixing member can fix the cover plate on the star shaft. After stacking the coiled pipe protection paper pads on the base, using the cover plate can limit the axial displacement of the coiled pipe protection paper pads. Thus, during transportation, even if the paper pad stacking device is overturned, the coiled pipe protection paper pads will not be scattered; the first groove can be inserted into the star shaft, making the connection between the cover plate and the star shaft more stable.

[0020] Furthermore, a plurality of pairs of limit grooves adapted to the positioning component are provided at the bottom end face of the plate body. After the coiled pipe protection paper pads are stacked on the base, when the cover plate is installed, the limit grooves are inserted into the positioning component and the first groove is inserted into the star shaft, which can make the whole body stable.

[0021] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0041] Refer to Figure 1 and 2The present invention proposes a coil protection paper pad, which solves the problem that the coil is easily damaged when the binding tape is extracted, and the coil is difficult to be accurately placed in the designated area when placed on the protective paper pad. The coil protection paper pad includes a circular bottom plate 100, four through grooves 110 arranged on the bottom plate 100 and extending from the edge of the bottom plate 100 toward the center of the circle, and the upper surface of the bottom plate 100 is provided with a plurality of pairs of positioning components 200 distributed along the circumference of the bottom plate 100 at intervals. The positioning component 200 includes a first positioning block 210 and a second positioning block 220. The first positioning block 210 and the second positioning block 220 are arc structures with the center of the bottom plate 100 as the center. When the coil is placed on the bottom plate 100, the coil is located between the first positioning block 210 and the second positioning block 220, and the binding tape for binding the coil is located between the through grooves 110.

[0042] The coil is in an annular shape as a whole, so the bottom plate 100 used to support the coil can be made into a circular shape to be sufficient to support the coil, which can save the manufacturing materials of the coil protection paper pad;

[0043] The binding belt for binding the coil is located in the through groove 110. When placing the coil, the binding belt will not hit the coil and cause the surface of the coil to dent. When removing the binding belt, the binding belt can also be cut short and pulled out from the through groove 110.

[0044] The first positioning block 210 and the second positioning block 220 can limit the position of the coil on the base plate 100, so that the coil is placed in the center of the base plate 100 as much as possible, so as to facilitate the adjustment of the strap to the through groove 110 without contacting the base plate 100, so that the pressure on the base plate 100 is more uniform, the service life of the base plate 100 is extended, and the coil can be better protected.

[0045] The angle between the center of two adjacent through grooves 110 and the center line formed by connecting the center of the bottom plate 100 is between 89° and 91°, the intervals between the multiple through grooves 110 are almost equal, and the spacing between the binding bands on the coil is also almost equal, so the fixing and packaging effects will be better; the main function of the through groove 110 is to facilitate the extraction of the binding band, so the position of the through groove 110 does not require to be particularly accurate, and a certain error is allowed, which will be more convenient during processing.

[0046] In order to facilitate the placement of the coil, in one embodiment of the present invention, the spacing between the two sides of the through groove 110 is W1, and the width of the strap used to bind the coil is W2, W1≥W2+5cm. Only when the width of the through groove 110 is greater than the width of the strap can the strap be located in the through groove 110, and the quality of the coil will not be affected when the strap is removed; if W1≥W2+5cm, a gap of 5cm can be left to facilitate the placement of the coil.

[0047] In addition, each set of positioning components 200 is located between two adjacent through grooves 110. The radian of the first positioning block 210 and the second positioning block 220 is between π / 4 and π / 3. The positioning components 200 are evenly distributed on the surface of the bottom plate 100, and the positioning effect on the coiled pipe will be better. Multiple pairs of positioning components 200 are arranged at intervals, and the through groove 110 is located between two adjacent pairs of positioning components 200. When placing the coiled pipe on the bottom plate 100, the binding strap needs to be aligned with the through groove 110. After the positioning components 200 are arranged between two adjacent through grooves 110, when placing the coiled pipe, first adjust the coiled pipe to adjust the position of the binding strap between two adjacent pairs of positioning components 200. After lowering the coiled pipe by a certain distance, make fine adjustments, align the binding strap with the through groove 110, and finally complete the placement of the coiled pipe, reducing the contact between the binding strap and the bottom plate 100 during the placement process, thereby preventing extrusion or friction of the pipe material.

[0048] Refer to Figure 3 , of course, the sides of the first positioning block 210 and the second positioning block 220 can also be flush with the sides of the through groove 110. In this way, the blocking effect and positioning function of the positioning component 200 will be better. Moreover, during production, two annular bodies can be produced on the surface of the bottom plate 100, and the positioning component 200 can be directly formed when cutting the through groove 110.

[0049] The thickness of the bottom plate 100 is between 7 and 10 mm. When the thickness of the bottom plate 100 is less than 7 mm, the protective effect of the coiled pipe protection paper pad on the coiled pipe is not good; when the thickness is greater than 10 mm, it is unnecessary, as the protective ability will not increase, and it will waste too much raw material, increasing the production cost.

[0050] Refer to Figure 4 , in an embodiment of the invention, a structure for facilitating the stacking of the coiled pipe protection paper pads is proposed. A plurality of pairs of positioning grooves 230 adapted to the positioning components 200 are provided on the bottom end surface of the bottom plate 100. The depth of the positioning grooves 230 is greater than the heights of the first positioning block 210 and the second positioning block 220 to enable the multi-layer coiled pipe protection paper pads to be stacked on top of each other. After stacking, the cooperation between the positioning components 200 and the positioning grooves 230 can limit the relative movement between the coiled pipe protection paper pads, making the overall stacked structure more stable and facilitating the storage of the coiled pipe protection paper pads.

[0051] Refer to Figures 5 to 7, the present invention also provides a paper pad stacking device for placing the stacked multi-layer coil pipe protection paper pads and facilitating the transportation of the paper pads. The paper pad stacking device includes a circular base 300, a star shaft 310 arranged at the central position of the base 300, and the above-mentioned coil pipe protection paper pads. A through hole 120 is provided at the central position of the bottom plate 100. A plurality of pairs of limiting blocks 320 whose shapes are adapted to the positioning grooves 230 are provided on the upper surface of the base 300. When the multi-layer coil pipe protection paper pads are stacked on the base 300, the star shaft 310 passes through a plurality of through holes 120 to radially position the multi-layer coil pipe protection paper pads, and the limiting blocks 320 are inserted into the positioning grooves 230 to limit the rotation of the multi-layer coil pipe protection paper pads.

[0052] The star shaft 310 and the limiting blocks 320 can radially position the multi-layer coil pipe protection paper pads to prevent the coil pipe protection paper pads from moving on the base 300. The limiting blocks 320 can also prevent the coil pipe protection paper pads from rotating, so that the coil pipe protection paper pads can be stable on the base 300 and will not be scattered during transportation; the circular base 300 is not easy to hurt people during hoisting, and can save materials and reduce production costs.

[0053] The paper pad stacking device further includes a cover plate 400 and a fixing member 500. The cover plate 400 includes a circular plate body 410, a first groove 420 arranged at the bottom end face of the plate body 410 and adapted to the star shaft 310, and a jack 430 arranged on the upper end face of the plate body 410 and communicated with the first groove 420. The fixing member 500 includes a rotating disk 510 and a threaded shaft 520 arranged at the bottom of the rotating disk 510. A threaded hole 440 is provided at the end of the star shaft 310. After the coil pipe protection paper pads are stacked on the base 300, the threaded shaft 520 is passed through the jack 430 and then threadedly engaged with the threaded hole 440, and the cover plate 400 can be fixed on the star shaft 310 to limit the axial displacement of the coil pipe protection paper pads. Thus, during transportation, even if the paper pad stacking device is overturned, the coil pipe protection paper pads will not be scattered; the first groove 420 can be inserted into the star shaft 310, making the connection between the cover plate 400 and the star shaft 310 more stable.

[0054] A circular groove (not marked in the figure) is provided on the rotating disk 510. The bottom of the groove is connected with a rotating disk 530. There is a gap between the rotating disk 530 and the circumferential inner wall of the groove to facilitate a finger to extend into the groove to hold the rotating disk 530 and rotate, so as to threadedly engage the fixing member 500 with the star shaft 310 or release the matching relationship between the fixing member 500 and the star shaft 310.

[0055] In addition, a second groove 450 is also provided on the upper end face of the cover plate 400, and the second groove 450 is adapted to the rotating disk 510. When the threaded shaft 520 is gradually engaged with the threaded hole 440, the rotating disk 510 will enter the second groove 450, making the fixing member 500 not easy to loosen and maintaining a firm connection.

[0056] A plurality of pairs of limiting grooves 460 adapted to the positioning assembly 200 are provided on the bottom end surface of the plate body 410. After the coil protection paper pads are stacked on the base 300, the cover plate 400 is installed. The insertion of the limiting grooves 460 into the positioning assembly 200 and the insertion of the first grooves 420 into the star shafts 310 can keep the whole stable.

[0057] The diameter of the bottom plate 100 is the same as that of the cover plate 400 and is larger than the diameter of the bottom plate 100. During transportation, the paper pad stacking device can be turned over so that the edges of the bottom plate 100 and the cover plate 400 contact the ground, and it can be moved in a rolling manner. The multi-layer coil protection paper pads on the star shafts 310 will not contact or rub against the ground.

[0058] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
