Description

Plasticine strip preparation device and preparation method

Technical Field

The invention relates to a plasticine strip preparation device and a preparation method.

Background

In the blade production process in the field of wind power generation, the bonding width and the bonding thickness of the blades during die assembly and bonding are of great importance, and the reliability of the blades is concerned. Therefore, trial mold clamping is performed before the mold clamping and bonding process is performed, mold clamping gaps (bonding thicknesses) between the blade shell and the web and between the blade shell and the bonding angle are detected by using the rubber clay strips, and then the amount of structural adhesive required when mold clamping and bonding are performed is determined according to the detection result.

At present, in the field of wind power, the preparation method of the plasticine strip for detecting the closing gap of the blade is mainly purely manual processing molding or extrusion molding. The problems of poor size consistency, low efficiency, time and labor waste exist in the pure manual processing and forming. Extrusion molding ensures dimensional consistency in thickness during extrusion, but the extruded elongated cylinders are spirally stacked and need to be manually assembled into the required size for segmentation. Therefore, there is still a problem of dimensional inconsistency in the length of the plasticine strip.

When the size consistency of the manufactured plasticine strip is poor, the measurement precision of the mold closing gap is influenced. In addition, the extruded plasticine strip is cylindrical and is easy to slide when placed in the bonding area, which affects the measurement accuracy of the mold clamping gap.

Further, taking the case where the blade length is about 60m as an example, the amount of the rubber band required for one trial mold of one blade at the time of bonding is at least 360. The larger the blade size, the more strips of plasticine are required. For pure manual forming, the amount of the plasticine strip required for one blade to test the mold at a time needs to be invested in about 12 man-hours. If the detected die closing gap does not meet the requirement, repeated trial die closing is needed, the number of the needed plasticine strips is multiplied, and the man-hour required to be invested is also multiplied. However, the manual preparation has a problem of low efficiency, and the increase in labor time also leads to an increase in cost.

In addition, the plasticine strip is required to be wrapped by a plastic film whether the plasticine strip is processed and formed by pure hands or extruded. However, since the plastic film is easy to fall off, when the mold closing gap is detected, the plasticine strip is extruded by the blade mold, and the plasticine overflows the plastic film and adheres to the adhesion area of the blade shell or adheres to the plastic film, so that the plasticine strip is difficult to clean. Not only causes additional work load, but also results in non-recyclable plasticine strips and wrapping material.

Detailed Description

In order that those skilled in the art will better understand the present invention, specific embodiments thereof will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 8, a plasticine strip preparation apparatus and a preparation method according to an embodiment of the present invention will be described in detail.

The plasticine strip preparation apparatus according to the embodiment of the present invention includes: a plasticine forming module 10, in the shape of a box, having a chamber for forming a block of plasticine; and the cutting tool is used for cutting the blocky plasticine in the horizontal direction and the vertical direction so as to obtain the plasticine strip. The plasticine strip manufactured by the plasticine strip preparation device can be used for detecting the blade mold closing gap.

Referring to fig. 3 to 5, the plasticine-forming module 10 according to the embodiment of the present invention may be an assembled frame mold, forming a cavity in a regular hexahedron shape by assembling a plurality of plates. The desired mass of plasticine may be formed after filling and compacting the plasticine in the chamber.

By way of example, a board according to an embodiment of the present invention may be a wooden board. Embodiments are not so limited and any other lightweight, easily machined, and low cost plate may be used.

The plasticine forming module 10 may have a multi-layer structure in the vertical direction (height direction T) to make a plurality of plasticine strips in a batch at a time. An example of a plasticine forming module 10 having a three layer structure is shown in figure 3. The embodiment is not limited thereto but may be formed in a structure of one layer, two layers, four layers, five layers or more.

The thickness of each layer of the plasticine forming module 10 may be the same as the thickness of the plasticine strip 70. In an embodiment of the present invention, each layer of the plasticine forming module 10 can be surrounded by four plates of the same height to form the plasticine making area S. Thereafter, a plurality of layers may be sequentially stacked from bottom to top, thereby forming the plasticine-forming module 10 having a multi-layer structure.

By way of example, the plates of the same layer of the plasticine forming module 10 may be connected by a "criss-cross" connection.

Referring to fig. 4 and 5, in the same layer of the plasticine forming module 10, four plates cross-connected to each other surround to form a plasticine making area S. The four plates include two first plates 11 arranged in parallel and two second plates 12 perpendicular to the two first plates 11. As shown in fig. 4 and 5, the four plates may include two first plates 11 disposed in a length direction (L direction) and two second plates 12 disposed in a width direction (W direction).

First and second card slots 111 and 121 may be formed at the cross-connection of the first plate 11 disposed in the length direction and the second plate 12 disposed in the width direction to each other, respectively. The first card slot 111 of the board 11 disposed in the length direction may be opened upward, and the second card slot 121 of the second board 12 disposed in the width direction may be opened downward. Therefore, in the case where the first and

second plates

11 and 12 cross each other, the "cross-slotted cross" type connection of the first and

second plates

11 and 12 can be achieved by bringing the first and second card slots 111 and 121 facing each other close to each other and bringing the groove bottoms of the first and second card slots 111 and 121 into contact with each other.

The width of the first card slot 111 may be the same as the thickness of the second plate 12, and the depth of the first card slot 111 may be half the height of the second plate 12. Similarly, the width of the second card slot 121 may be the same as the thickness of the first plate 11, and the depth of the second card slot 121 may be half the height of the first plate 11. Therefore, when the first and second card slots 111 and 121 facing each other are gradually brought close to each other and the slot bottoms are brought into contact, the first card slot 111 can be perfectly engaged with the second board 12, and the second card slot 121 can be perfectly engaged with the first board 11, so that the first board 11 and the second board 12 can be stably engaged and fixed with each other.

However, the depth dimensions of the first card slot 111 and the second card slot 121 are not limited thereto as long as the sum of the depths of the first card slot 111 and the second card slot 121 is equal to the height of the board. Although fig. 5 illustrates a manner in which the first board 11 and the second board 12 are connected by a card slot, embodiments of the present invention are not limited thereto, and the first board 11 and the second board 12 may be connected to each other by other suitable manners.

As an example of the manner of assembly between the various layers of the plasticine forming module 10, a "mortise and tenon" connection may be employed.

Referring to fig. 5, the first plate 11 disposed in the width direction may have at least one groove 122 formed on an upper surface thereof, i.e., a mortise and tenon joint, and at least one protrusion 123 formed on a lower surface thereof, i.e., a tenon in the mortise and tenon joint, 11. The positions and sizes of the grooves 122 and the protrusions 123 of the respective first plates 11 may correspond to each other. Therefore, when a plurality of first plates 11 are arranged in the vertical direction, the first plate 11 positioned at the upper layer and the first plate 11 positioned at the lower layer can be stably connected by the protrusions 123 and the grooves 122 (tenon and mortise work) corresponding to each other.

An example in which three grooves 122 are formed on the upper surface of the first plate 11 and three protrusions 123 are formed on the lower surface of the first plate 11 is shown in fig. 5.

However, the embodiment is not limited thereto, and a protrusion may be formed on the upper surface of the first plate 11 and a groove may be formed on the lower surface of the first plate 11. Further, the number of the projections and the grooves is not limited to three, and may be one, two, four, five or more. In addition, protrusions and grooves may also be formed on the second plate 12.

The connection method between the layers is not limited to the above connection method, and other connection methods such as pin connection and roban lock may be used.

By way of example, grips, such as the first and second through-

holes

114, 124, may be formed at both ends of each plate to facilitate the operator's picking the plates when assembling and disassembling the plasticine molding module 10. The edges of the first and second through

holes

114 and 124 may be rounded to prevent cutting of the worker's hands.

Although this embodiment shows the grip in the form of a through hole, the present invention is not limited thereto, and the grip may be formed by forming a groove or otherwise installing a handle on the end surfaces of both ends of the first and

second plates

11 and 12.

Referring to fig. 1 and 2, the plasticine strip preparing apparatus may further include a plasticine flattening apparatus 20 to press the plasticine after filling the plasticine in the plasticine forming module 10, thereby forming a block-shaped plasticine. However, the embodiment is not limited thereto, and the plasticine may be manually flapped, compacted, and flattened using a flat bottom stone hammer.

The plasticine flattening apparatus 20 according to the present invention may include a base plate 21 as a main body frame, a top plate 23, and a flattening member 24. The plasticine moulding module 10 may be mounted on the base plate 21. The top plate 23 may be supported above the plasticine forming module 10, for example, the top plate 23 may be supported by the side plates 22. The flattening member 24 may be plate-shaped, interposed between the top plate 23 and the plasticine molding module 10, and the flattening member 24 may be driven by a driving device to directly flap, flatten and compact the plasticine when molding a lump of plasticine.

By way of example, the platen 24 may be driven by a motor and crankshaft. Referring to fig. 1 and 2, the plasticine-flattening apparatus 20 may further include a motor 25 and a crankshaft link mechanism on the upper surface of the top plate 23. The axis of the crankshaft 26 of the crankshaft linkage may be disposed in a horizontal plane. One end of the crankshaft 26 may be connected to the motor 25, and the other end may be connected to the piston 27.

Alternatively, the piston 27 may have a substantially cylindrical appearance. The lower portion of the piston 27 is vertically insertable into a through hole formed in the top plate 23 to be connected to the flattening member 24. As the crankshaft 26 is eccentrically driven, the piston 27 and the flattening member 24 are reciprocated up and down in the vertical direction to flap, compact and flatten the plasticine.

Although fig. 1 and 2 show the flattening member 24 driven by the motor 25 and the crankshaft 26, the present invention is not limited thereto, and the flattening member 24 may be reciprocated up and down by other eccentric transmission means such as a cam.

Referring to fig. 2, a pressure sensor 241 may be disposed at a corner of the pressing member 24 to sense a force applied to the pressing member 24 during the tapping, compacting and pressing operations, and convert the pressure signal into a usable output signal such as an electrical signal, so as to balance and control the impact force of tapping and the force of compacting and pressing according to the sensed force applied to the pressing member 24. As an example, the pressure sensors 241 may be provided at four corners of the pressing member 24 to uniformly measure the pressure over the entire surface.

The cutter according to the embodiment of the present invention can cut the block-shaped plasticine in the horizontal direction and the vertical direction to obtain a plasticine strip having a rectangular parallelepiped shape.

As an example, the cutting tool according to an embodiment of the present invention may include a horizontal cutting tool 30 and a vertical cutting tool 40.

The horizontal cutting tool 30 may include a cutting portion and handle portions at both ends of the cutting portion. Referring to fig. 6, the length D of the cutting portion may be equal to or greater than the width D of the block-shaped plasticine 50 to be cut, and the horizontal cut 30 may be cut in the direction a when cutting the block-shaped plasticine 50.

The vertical cutting blade 40 may include a plurality of cutting blades arranged in parallel with each other. The interval between two cutters adjacent to each other among the plurality of cutters of the vertical cutter 40 may be the same as the width of the plasticine strip 70 to ensure that the size of the cut plasticine strip 70 meets the condition.

Referring to fig. 7, both ends of the plurality of cutting blades of the vertical cutting blade 40 may be connected with a support frame 41 to secure structural stability. As an example, the support frame 41 may have a rectangular shape, but the embodiment is not limited thereto, and may also have a square, oval, or other shape.

Handles 42 are provided on the outer sides of the support frames 41 facing away from each other to facilitate the operation of the vertical cutting blade 40 by the operator.

The plurality of cutting blades and handles 42 of the vertical cutting blade 40 may be welded, for example, to the inner and outer surfaces of the support frame 41, respectively.

As another alternative, the horizontal cutter 30 and the vertical cutter 40 may be integrated into one mechanical control device. Specifically, the horizontal cutting tool 30 and the vertical cutting tool 40 are positioned in the same coordinate system, and when cutting is performed, the horizontal cutting tool 30 and the vertical cutting tool 40 are respectively controlled by the control device to cut plasticine along a preset path, so that a reference surface does not need to be manually controlled, the accuracy is high, and the operation efficiency is high.

A method for manufacturing a plasticine strip according to an embodiment of the present invention will be described in detail below with reference to the above-described plasticine strip manufacturing apparatus.

The preparation method of the plasticine strip can comprise the following steps: preparing blocky plasticine; the block-shaped plasticine is cut in the horizontal direction and the vertical direction, thereby obtaining a plasticine strip.

By way of example, a block of plasticine may be prepared using the plasticine forming module 10 described above. In the preparation of a slab of plasticine, the cavities or cavities of the plasticine forming module 10, in particular the dead corners of the cavities, can be filled, for example by manual operation. In addition, the filling amount of the plasticine can be 1-2 cm higher than the upper edge of the plasticine forming module 10, so that the plasticine in the plasticine forming module 10 can still fully fill the cavity of the plasticine forming module 10 after the plasticine is compacted and flattened.

After the filling is completed, the plasticine can be flapped, compacted and flattened by the flattening piece 24, and the flattening piece 24 can be provided with a pressure sensor 241 to sense the stress condition of the flattening piece 24 during the flapping, compacting and flattening operation, and the impact force of the flapping and the force of the compacting and flattening can be controlled in a balanced manner according to the sensed stress condition.

When the plasticine is sufficiently pressed so that the plasticine becomes equal in height to the plasticine molding block 10, a block-shaped plasticine having a predetermined size can be obtained.

The horizontal cross-sectional dimension of the prepared blocky plasticine can correspond to the dimension of the plasticine strip. For example, the length of the prepared block plasticine may be the same as the length of the plasticine strip, and the width of the prepared block plasticine may be an integer multiple of the width of the plasticine strip.

The individual sheets that make up the plasticine forming module 10 need to be removed prior to performing the cutting operation.

Taking cutting the plasticine in the first layer of the plasticine forming module 10 as an example, the first plate 11 in the length direction of the first layer of the plasticine forming module 10 is removed first, and then the second plate 12 in the width direction of the first layer of the plasticine forming module 10 is removed, thereby exposing plasticine corresponding to the size of the inner cavity of the first layer of the plasticine forming module 10. Subsequently, a cutting operation may be performed on the exposed plasticine.

In performing the cutting operation, first, horizontal cutting is performed along the upper edges of the first plate 11 and the second plate 12 of the second layer located below the first layer using the horizontal cutting tool 30, resulting in a flat plasticine block having the same thickness as that of the plasticine strip. Subsequently, the resulting flat plasticine block may be subjected to vertical cutting with a vertical cutting blade 40, thereby obtaining a plasticine strip of a suitable size. Figure 8 schematically shows a finished plasticine strip 70 placed on the flat plate 60.

The same horizontal and vertical cutting steps as described above can be repeated for the remainder of the block of plasticine, eventually cutting the entire block of plasticine layer by layer into a plurality of plasticine strips 70.

After the preparation of the plasticine strips is completed, the prepared finished plasticine strips 70 can be neatly placed in a storage box, so that the subsequent wrapping of the plasticine strips 70 can be conveniently carried out.

The subsequent wrapping method of the plasticine strip 70 will be described in detail with reference to fig. 9 to 11.

The wrapping method of the plasticine strip 70 may include: preparing a release film 90 with the release film 90 facing upward; preparing a double-sided pressure-sensitive adhesive tape 80, and sticking one surface of the double-sided pressure-sensitive adhesive tape 80 to one corner of the anti-adhesive film surface of the anti-adhesive film 90; horizontally placing the rubber mud strip 70 on the anti-sticking film surface of the anti-sticking film 90; the anti-sticking film 90 is wrapped on the plasticine strip 70 from the other corner opposite to the one corner, and the tightness is moderate and is not easy to be over-tightened or over-loosened when wrapping; when the release film 90 is wrapped to the position of the double-sided pressure-sensitive adhesive tape 80, the release film 83 of the double-sided pressure-sensitive adhesive tape 80 is peeled off, and the other surface of the double-sided pressure-sensitive adhesive tape 80 is stuck to the base material surface of the release film 90.

After the wrapping step is completed, the wrapped plasticine strips 70 can be neatly placed in a storage box to be used for detecting the die closing gap.

When the plasticine strip 70 is placed, the plasticine strip 70 is placed in the center of the anti-sticking film 90, and the placing direction of the plasticine strip 70 can be perpendicular to the direction from the other corner to the corner along which the anti-sticking film 90 is wrapped, so as to obtain a better wrapping effect.

The size of the release film 90 may be determined according to the size of the mastic strip 70. As an example, in the case where the release film 90 has a square shape, the diagonal distance of the release film 90 is preferably 2 times the length of the mastic strip 70 to ensure that the mastic strip 70 is sufficiently wrapped. Also, in the case where the anti-sticking film 90 has a square shape, the mastic strip 70 may be placed along the diagonal of the square shape.

Although the case where the release film 90 has a square shape is shown above, the present invention is not limited thereto, and the release film 90 may have other shapes. For example, the release film 90 may be a rectangular film, in which case a plaster strip 70 may be placed along the long side of the rectangle, and the double-sided pressure-sensitive adhesive tape 80 may be stuck to the long side of the rectangular film, and then wrapping of the plaster strip may be performed. As another example, a rectangular film sleeve may also be used to wrap the plasticine strip 70.

Both the release film 90 and the double-sided pressure-sensitive adhesive tape 80 according to the embodiment of the present invention employ a pressure-sensitive adhesive. Pressure sensitive adhesives are a special type of adhesive that can be adhesively bonded by finger pressure without the need for heat, solvents, or other means. In general, pressure-sensitive adhesives are not used directly for adhesion, but are applied to a tape-shaped substrate to produce various pressure-sensitive adhesive products.

The release film 90 according to an embodiment of the present invention may include a plastic substrate 91 of polyester or the like, a single layer of pressure-sensitive adhesive 92, and a release film 93 coated with a silicone coating 94 on one side, which are sequentially stacked, the lower surface of the plastic substrate 91 of polyester or the like constituting a substrate surface that is easily adhered, and the silicone coating 94 constituting a release film surface that is not easily adhered.

The single layer of pressure sensitive adhesive 92 is primarily intended to be non-reinforced with respect to the substrate, and is conformable and permanent. The silicone coating 94 has the characteristics of low viscosity, weak surface tension, small surface energy and strong film forming capability, and the low surface tension and the low surface energy enable the silicone coating to have the characteristics of hydrophobicity, adhesion resistance and lubrication. Therefore, the anti-sticking film 90 can solve the problem that the plasticine is extruded by external force and is not easy to remove when being bonded with the plastic film.

In addition, in practical use, the plastic base materials 91 such as polyester and the anti-sticking film 93 can be distinguished by adopting two different colors, so that an operator can conveniently identify the anti-sticking film surface during wrapping operation, and the plasticine is attached to the anti-sticking film surface.

The double-sided pressure-sensitive adhesive tape 80 according to an embodiment of the present invention may include a pressure-sensitive adhesive 81, a plastic substrate 82 of polyester or the like, a pressure-sensitive adhesive 81, and a release film 83 coated with a silicone coating on both sides, which are sequentially stacked.

Pressure-sensitive adhesives are the most important components of pressure-sensitive adhesive tapes, and serve to provide pressure-sensitive adhesive properties to the tapes. The pressure-sensitive adhesive tape may further include a primer and a back-surface treatment agent, etc. The primer can be used for increasing the bonding strength of the pressure-sensitive adhesive and the base material. When the pressure-sensitive adhesive tape is used, the protective film is torn off, and the pressure-sensitive adhesive tape can be bonded with the surface of an adherend by lightly pressing the pressure-sensitive adhesive tape by utilizing the pressure-sensitive adhesive property of the pressure-sensitive adhesive. In addition, when the pressure-sensitive adhesive tape is torn off, the problem that the adhesive pollutes the surface of an adherend does not occur.

The double-layer pressure-sensitive adhesive 81 adopted by the invention mainly has the function of reinforcing a base material and has good stripping performance. The organic silicon coating has the characteristics of hydrophobicity, adhesion resistance and lubrication. Therefore, with the double-sided pressure-sensitive adhesive tape 80, not only the finger-pressure bonding but also the anti-sticking and lubricating effects can be achieved.

Referring to fig. 12, a process flow of applying the plasticine strip obtained by the plasticine strip manufacturing method according to the embodiment of the present invention to mold clamping gap detection will be described in detail, taking a blade having a length of 60m as an example.

For a blade with the length of 60m, the bonding width of a web bonding area is generally 100-110 mm, the bonding width of a front edge bonding area is generally 90-130 mm, and the bonding width of a rear edge bonding area is 150-220 mm.

Generally, the width of the rubber band 70 is preferably 30mm and the height thereof is preferably 20 mm. With the above blade bonding width dimension requirements, two length dimensions of the plasticine strip 70 can be determined: 150 mm. times.30 mm. times.20 mm and 230 mm. times.30 mm. times.20 mm (length. times.width. times.height).

The rubber clay strips with the size of 150mm multiplied by 30mm multiplied by 20mm can meet the detection requirements of a web bonding area, a front edge bonding area and a part of a rear edge bonding area. A rubber-plastered strip of dimensions 230mm x 30mm x 20mm may suffice for the remaining trailing-edge bonding area. The plasticine strips with the two sizes can be manufactured by adopting the preparation method of the plasticine strip.

The production of the plasticine strip of steps S01 to S05 can refer to the production method described above, and the description is not repeated here.

In step S06, a rubber blanket is set, and the obtained rubber blanket is set at a designated position in accordance with a process Standard Operating Program (SOP). Specifically, when the daub strips are used for detecting the die closing gaps between the blade shell and the web and between the blade shell and the bonding angle, the daub strips are required to be placed every other meter in a die closing bonding area, and the width of each daub strip is consistent with that of the bonding area. In the rear edge bonding area, one end of the plasticine strip needs to exceed the inner edge of the blade mould by not less than 20mm, and the other end of the plasticine strip needs to reach the edge of the core material. In the front edge bonding area of the blade mold, one end of the plasticine strip is pressed on the outer edge of the blade mold, and the other end of the plasticine strip exceeds the front edge bonding angle by 10-20 mm. In the bonding area of the web plate of the blade, two ends of the plasticine strip need to exceed the bonding flange of the web plate by 10-20 mm. A25 cm-long rubber clay strip is placed on each lightning arrester (comprising aluminum, copper columns and copper plates), and two 25 cm-long rubber clay strips are placed on each counterweight box.

In step S07, the trial mold clamping detection is performed to detect the mold clamping gap and is performed in accordance with the mold clamping detection request of the process SOP. Specifically, the thickness of the plasticine strip at each position was measured with a vernier caliper and recorded. Generally, the thickness of the glue layer is required to be 0.5-8 mm. And processing the excessive thickness area according to a relevant finishing flow.

In step S08, the used rubber band is collected, and after the mold clamping gap detection is completed, the rubber band placed in the adhesion area is collected in a storage box.

In step S09, the used plasticine strip/anti-sticking film is recovered, and the used plasticine strip and anti-sticking film are recovered for recycling.

And step S10, storing the recovered plasticine strips, hermetically wrapping the recovered plasticine strips by using a preservative film, and storing in dark to prevent the recycled plasticine strips from being air-dried and unusable.

In conclusion, according to the plasticine strip preparation method and the plasticine strip preparation device, the workload required for preparing the plasticine strip can be obviously reduced, the operation efficiency is improved, the operation period is shortened, the time and the labor are saved, and the cost is reduced. Meanwhile, the plasticine strip manufactured by the preparation method and the preparation device of the plasticine strip have higher size consistency. In addition, the plasticine strip manufactured by the preparation method and the preparation device of the plasticine strip can be applied to blade mold closing gap detection. The rubber clay strip has higher size consistency, so that the detection precision of the die closing gap of the blade can be ensured. In addition, the plasticine strip preparation method and the plasticine strip preparation device can be used for preparing the cuboid plasticine strip, so that the problem that the cylindrical plasticine strip is easy to slip from the bonding area in the prior art is solved. In addition, according to the preparation method of the plasticine strip, the problems that the wrapping material falls off, the plasticine overflowing by extrusion is stuck to the blade bonding area and the wrapping material is not easy to clean can be solved, the problem that the plasticine and the wrapping material are recycled can be solved, and the manufacturing cost is further effectively reduced.
