Description

Technical Field

[0001] The invention relates to the technical field of composite rod production, in particular to a variable-diameter yarn bundle constraint control mechanism for a composite rod production line. Background Art

[0002] Composite poles have many advantages such as light weight, high structural strength, good corrosion resistance and good insulation performance, and are widely used in fields such as power grid construction.

[0003] In the current production process of composite poles, the glass fiber bundles must first be fully impregnated with glue and then wound and laid on the pole mold. Traditional glass fiber bundles are usually wound and laid on the pole mold in a small angle cone. The entire set of laying and winding equipment is extremely complex, troublesome to maintain, and expensive. In addition, the efficiency of continuous production of composite poles is low.

[0004] In addition, for the composite material rod itself, since its traditional production process adopts a small-angle conical winding, the axial force of each glass fiber bundle cannot be fully utilized, resulting in low tension of the glass fiber bundle and large deflection of the composite material rod after molding. In order to solve the problem of large deflection of the composite material rod after molding, it is necessary to increase the number of winding layers of the glass fiber bundle in advance during production to reduce the deflection index. However, increasing the number of winding layers of the glass fiber bundle will increase the overall raw material consumption and the total weight of the product after molding, thereby increasing production costs and transportation costs.

[0005] Based on the above background, the inventor has designed a variable diameter yarn bundle constraint control mechanism for a composite rod production line to solve at least one of the above problems, and thus proposed the present application. Summary of the invention

[0006] The purpose of the present application is to provide a variable diameter yarn bundle constraint control mechanism for a composite material rod production line, which is used to solve the problem of low tension of glass fiber bundles after laying and winding in the prior art.

[0009] Optionally, the movable end and the fixed end are detachably connected to two ends of the elastic shrink rod respectively; The cross-sectional shape of the elastic shrinkable rod is any one of a circle, an ellipse, and an oval.

[0010] Optionally, the shape of the inner ring of the static disk is: an N-pointed star with N convex corners, or: a combination of N convex corners and a circle, and the N convex corners are evenly distributed along the circumference of the circle; Wherein: N is a natural number greater than 3.

[0011] Optionally, the number of the constraint unit assemblies is N groups, and the number of the constraint unit assemblies is the same as the number of the outer convex corners of the inner ring of the static disk; The moving carrier plate is provided with N glue tank installation grooves evenly distributed along its circumference and used for installing glue storage tanks, and the glue tank installation grooves are all arranged close to the outer convex corners of the inner ring of the static plate; A glue lowering port is also provided at the folded corner of the outward convex folded corner.

[0012] Optionally, it also includes a glue storage tank for collecting glue dripping during the winding and laying process of the yarn bundle; The glue storage tank is inserted into the glue tank installation slot; The glue storage tank comprises a tank body with an internal cavity, and a glue connection port provided on the side wall thereof and protruding outward, wherein the glue connection port is adapted to a lower glue port provided at the corner of the convex corner; The shape of the glue tank installation groove is adapted to the cross-sectional shape of the glue storage tank.

[0013] Optionally, the glue storage tank also includes a partition plate disposed in the tank body and used to divide its internal cavity into a glue storage chamber and a glue inlet chamber. The A end of the partition plate is disposed close to the glue connection port, and there is a distance between the B end of the partition plate and the inner circumferential wall of the tank body.

[0014] Optionally, the tank body is cylindrical; It also includes a glue blocking plate fixed to the B end of the partition plate and extending toward one end close to the glue storage cavity.

[0015] Optionally, the inner ring of the static disk is circular in shape; The size of the inner ring of the moving disk is larger than the diameter of the inner ring of the static disk; A baffle is also provided on the moving carrier plate to prevent the glue from flowing out of the inner ring of the moving plate.

[0016] Optionally, it also includes a mounting seat arranged parallel to the carrier assembly, and the static carrier is fixedly connected to the mounting seat; The driving assembly includes a driving motor, a driving gear and a driven rack, wherein: The driving motor is fixed on the mounting seat, the driving gear is fixed on the output shaft of the driving motor, the driven rack is fixed on the outer peripheral wall of the dynamic carrier plate, and the driving gear and the driven rack are meshed with each other.

[0017] Beneficial effects of the present invention: 1. The present application uses a carrier plate assembly, a constraint unit assembly and a driving assembly, and can drive the dynamic carrier plate of the carrier plate assembly to rotate through the driving assembly, thereby causing relative rotation between the dynamic carrier plate and the static carrier plate. Since one end of the constraint unit assembly is fixed on the dynamic carrier plate, and the other end is connected to the static carrier plate along the radial sliding direction of the carrier plate assembly, when the dynamic carrier plate rotates relative to the static carrier plate and causes the distance between the two ends of the constraint unit assembly to change, the constraint unit assembly will be elastically deformed, and several groups of constraint unit assemblies symmetrically distributed along the circumferential direction of the carrier plate assembly can form an inner ring structure for constraining the yarn bundle. The size of the inner ring structure changes linearly after the elastic deformation of the constraint unit assembly occurs, and the distance between the yarn bundle located inside it and the surface of the pole mold can be constrained and controlled, thereby improving the uniformity, density and yarn bundle tension of the yarn bundle laying, and effectively solving the problems of the prior art.

[0018] 2. In the present application, the shape of the inner ring of the static disk is an N-pointed star with N convex corners, or a combination of N convex corners and a circle, so that when the constraint unit assembly of the present application is constraining the yarn bundle, the glue dripping from the yarn bundle due to pressure can flow into the groove formed by the convex corner under the action of gravity, which is convenient for collecting and cleaning the glue.

[0019] 3. The elastic shrinkage rod that plays a shrinkage constraint role in the constraint unit assembly of the present application is in the shape of a rod, which can increase the constraint force on the one hand, and on the other hand, a single shrinkage rod can also have a constraint effect on multiple yarn bundles, so that multiple yarn bundles can be constrained and controlled by multiple elastic shrinkage rods at the same time, thereby ensuring the stability of the yarn bundle constraint; In addition, due to the special material of the yarn bundle, the rod-shaped structure can be selected to avoid shear force on the yarn bundle during the constraint process, which may cause it to break. At the same time, the elastic shrinkage rod with the rod-shaped structure is convenient for regular cleaning of glue and maintenance.

[0020] 4. The present application also provides a glue storage tank on the static load plate, which can conveniently collect the glue that flows into the groove formed by the convex corner, thereby reducing the maintenance frequency of the entire device. A partition plate and a glue blocking plate are also provided in the glue storage tank, so that the glue storage tank can collect the glue that drips into the groove at the convex corner only when it is located in the lower area of ​​the static load plate. When it is located in the upper area of ​​the static load plate, the glue cannot flow back out of the glue storage tank, so that when performing maintenance, it is only necessary to pull out and replace the new glue storage tank.

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed", "opened", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a variable diameter yarn bundle constraint control mechanism for a composite material pole production line, comprising a carrier assembly 1, the carrier assembly 1 comprising a dynamic carrier 11 and a static carrier 12 arranged parallel to each other and rotatably connected, and a plurality of groups of constraint unit assemblies for constraining and controlling the distance between the axial yarn bundle and the outer wall of the pole mold, wherein: The dynamic loading plate 11 is provided with a dynamic plate inner ring 111, and the static loading plate 12 is provided with a static plate inner ring 121; Several groups of constraint unit assemblies are symmetrically distributed along the circumference of the carrier assembly 1, one end of the constraint unit assembly is slidably connected to the dynamic carrier 11 along the radial direction of the carrier assembly 1, and the other end is fixedly connected to the dynamic carrier 11 through the dynamic plate inner ring 111 and the static plate inner ring 121; It also includes a driving assembly 2 for driving the dynamic loading plate 11 to rotate on the static loading plate 12.

[0034] In this embodiment, through the carrier plate assembly 1, the constraint unit assembly and the driving assembly 2, the driving assembly 2 can drive the dynamic carrier plate 11 of the carrier plate assembly 1 to rotate, so that relative rotation occurs between the dynamic carrier plate 11 and the static carrier plate 12. Since one end of the constraint unit assembly is fixed on the dynamic carrier plate 11, and the other end is connected to the static carrier plate 12 along the radial sliding direction of the carrier plate assembly 1, when the dynamic carrier plate 11 rotates relative to the static carrier plate 12 and causes the distance between the two ends of the constraint unit assembly to change, the constraint unit assembly will be elastically deformed, and several groups of constraint unit assemblies symmetrically distributed along the circumferential direction of the carrier plate assembly 1 can form an inner ring structure for constraining the yarn bundle. The size of the inner ring structure changes linearly after the elastic deformation of the constraint unit assembly occurs, and the distance between the yarn bundle located inside it and the surface of the pole mold can be constrained and controlled, thereby improving the uniformity, density and yarn bundle tension of the yarn bundle laying, effectively solving the problems of the prior art.

[0035] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the constraint unit assembly includes an elastic shrink rod 31 which is arc-shaped and elastic, and a movable end 32 and a fixed end 33 fixed at both ends of the elastic shrink rod 31; The movable carrier plate 11 is provided with a strip-shaped sliding hole 112 arranged along its radial direction, and the movable end head 32 is slidably connected in the strip-shaped sliding hole 112; The fixed end 33 is fixedly connected to the static load plate 12. In this embodiment, the elastic shrink rod 31 is made of a metal material with relatively good elastic properties such as spring steel and titanium alloy to ensure durability.

[0036] In this embodiment, Figure 1 and Figure 2 As shown, there are 8 groups of constraint unit assemblies, and the 8 groups of constraint unit assemblies are evenly distributed along the circumference of the carrier body.

[0037] In this embodiment, the inner ring 111 of the moving plate and the inner ring 121 of the stationary plate are both circular in structure and have the same size.

[0038] In this embodiment, Figure 1 and Figure 2 As shown, the movable end 32 and the fixed end 33 are detachably connected to the two ends of the elastic contraction rod 31, respectively, so that the elastic contraction rod 31 can be easily removed for cleaning, maintenance, and replacement, thereby improving ease of use; The cross-sectional shape of the elastic shrink rod 31 is any one of circular, elliptical, and oval. In the present embodiment, the cross-sectional shape of the elastic shrink rod 31 is circular. The technicians can also set the cross-sectional shape of the elastic shrink rod 31 to other shapes without edges, such as elliptical and oval, as needed, to avoid the edges of the elastic shrink rod 31 cutting the yarn bundle. Other specific shapes are not given examples here.

[0039] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, it also includes a mounting seat 4 arranged parallel to the carrier plate assembly 1, and the static carrier plate 12 is fixedly connected to the mounting seat 4; The driving assembly 2 includes a driving motor 21, a driving gear 22 and a driven rack 23, wherein: The driving motor 21 is fixed on the mounting seat 4 , the driving gear 22 is fixed on the output shaft of the driving motor 21 , and the driven rack 23 is fixed on the outer peripheral wall of the dynamic carrier plate 11 . The driving gear 22 and the driven rack 23 are meshed with each other.

[0040] In this embodiment, the driven rack 23 is in the shape of an elongated strip, and is detachably fixedly connected to the circumferential end surface of the static load plate 12 to form a circular ring as a whole. Since the rotation angle of the static load plate 12 is usually less than 360°, technicians can also set the length of the driven rack 23 as needed, so that the driven rack 23 is in the shape of an arc as a whole after installation, thereby reducing equipment costs.

[0041] Embodiment 2: On the basis of the above-mentioned embodiment 1, Figures 3 to 5 As shown, in this embodiment, the shape of the stator inner ring 121 is: an N-pointed star with N convex corners, or: a combination of N convex corners and a circle, and the N convex corners are evenly distributed along the circumference of the circle; Wherein: N is a natural number greater than 3.

[0042] In this embodiment, the shape of the static disk inner ring 121 is: an 8-pointed star with 8 convex corners. In this embodiment, the number of constraint unit assemblies is 8 groups, and the movable end 32 and the fixed end 33 of the constraint unit assembly are staggered with the convex corners of the static disk inner ring 121.

[0043] The technicians may also set the shape of the inner ring 121 of the static disk to a combination of N convex corners and a circle as needed. In the present embodiment, since the yarn bundle needs to be sprayed with glue or dipped in glue before laying and winding, the yarn bundle has a large amount of glue. When the constraint unit assembly is constraining the yarn bundle, part of the glue attached to the yarn bundle will drip. In the present embodiment, the shape of the inner ring 121 of the static disk is set to be an 8-pointed star, so that the glue can flow into the groove formed by the convex corner after dripping and gather, which is convenient for maintenance personnel to clean.

[0044] The rest of the structure of this embodiment is the same as that of the above-mentioned embodiment 1 and will not be described again here.

[0045] Embodiment 3: Based on the above-mentioned embodiment 1 or embodiment 2, in this embodiment, if Figure 6 and Figure 7 As shown, the number of the constraint unit assemblies is N groups, and the number of the constraint unit assemblies is the same as the number of the outer convex corners of the inner ring 121 of the static disk; The moving carrier plate 11 is provided with N glue tank installation grooves 113 evenly distributed along its circumference and used to install the glue storage tank 5, and the glue tank installation grooves 113 are all arranged close to the outer convex corners of the inner ring 121 of the static plate; A glue lowering port is also provided at the corner of the convex corner. In the present embodiment, after the glue drips, it flows into the groove formed by the convex corner and gathers. Then, under the action of gravity, it can drip into the glue tank mounting groove 113 through the glue lowering port. A glue storage tank 5 is provided in the glue tank mounting groove 113, and the glue storage tank 5 has a glue connecting port 52 protruding outward and adapted to the glue lowering port. Therefore, the glue can directly flow into the glue storage tank 5 for temporary storage, and the glue in the glue storage tank 5 can be replaced after a certain amount of glue is collected.

[0046] Specifically, in this embodiment, if Figure 6 and Figure 7 As shown, it also includes a glue storage tank 5 for collecting glue dropped during the winding and laying process of the yarn bundle; The glue storage tank 5 is inserted into the glue tank installation groove 113; The glue storage tank 5 comprises a tank body 51 having an internal cavity, and a glue connection port 52 provided on the side wall thereof and protruding outward, wherein the glue connection port 52 is adapted to a lower glue port provided at the corner of the convex corner; The shape of the glue tank installation groove 113 is adapted to the cross-sectional shape of the glue storage tank 5 .

[0047] In this embodiment, the tank body 51 of the glue storage tank 5 is cylindrical in shape, and the glue connection port 52 extending from the tank body 51 can not only play a role in glue connection, but also play a role in accurate positioning, which is convenient for operators to install.

[0048] Specifically, in this embodiment, if Figure 6 and Figure 7 As shown, the glue storage tank 5 also includes a partition plate 53 arranged in the tank body 51 and used to divide its internal cavity into a glue storage chamber 511 and a glue inlet chamber 512. The A end of the partition plate 53 is arranged close to the glue connecting port 52, and there is a distance between the B end of the partition plate 53 and the inner peripheral wall of the tank body 51.

[0049] In this embodiment, by providing a partition plate 53, the cavity inside the tank body 51 can be divided into a glue storage cavity 511 and a glue inlet cavity 512. Figure 7 , the A end of the partition plate 53 is arranged near the glue connection port 52, and there is a distance between the B end of the partition plate 53 and the inner peripheral wall of the tank body 51, so that when the glue storage tank 5 is in the lower area of ​​the dynamic carrier plate 11, a part of the glue flowing into the glue storage tank 5 is located in the glue inlet cavity 512, and the other part is located in the glue storage cavity 511. At this time, the partition plate 53 is in a tilted downward state. As the dynamic carrier plate 11 rotates, the position of the glue storage tank 5 gradually rises, and the glue in the glue inlet cavity 512 will flow into the glue storage cavity 511. At this time, there is no longer a large amount of glue remaining in the glue inlet cavity 512. At this time, the partition plate 53 is in a horizontal or tilted upward state, and the glue cannot enter the glue inlet cavity 512 due to the obstruction of the partition plate 53. As the position of the glue storage tank 5 continues to rise, when the glue storage tank 5 is in the upper area or even the top area of ​​the dynamic carrier plate 11, the B end of the partition plate 53 is located above the A end, and the glue is blocked by the partition plate 53 and cannot enter the glue inlet cavity 512. 12, it is also impossible for the glue to flow out through the glue connection port 52 set on the tank body 51, and with the rotation of the dynamic carrier 11, when the position of the glue storage tank 5 moves downward from the top area of ​​the dynamic carrier 11, the position of the glue connection port 52 on the tank body 51 will gradually rise, and when the partition plate 53 is in a horizontal state or tilted downward, the position of the glue connection port 52 has risen to a higher state. At this time, the glue inside the tank body 51 cannot flow back. Therefore, in this embodiment, the partition plate 53 is designed to separate the cavity inside the tank body 51 into a glue inlet cavity 512 and a glue storage cavity 511. After the glue enters the tank body 51, after the dynamic carrier 11 is rotated, the partition plate 53 is in different inclination states at different positions, so that the glue storage cavity 511 of the tank body 51 on the dynamic carrier 11 forms a storage space that can only enter but not exit, which is convenient for glue collection and can also try to avoid the glue from dripping onto the yarn bundle again, affecting the overall performance of the composite material rod after molding.

[0050] Specifically, in this embodiment, if Figure 6 and Figure 7 As shown, the tank body 51 is cylindrical; It also includes a glue blocking plate 54 fixed to the B end of the partition plate 53 and extending toward one end close to the glue storage cavity 511 . The cross-sectional shape of the glue blocking plate 54 is an arc shape. A glue inlet channel 513 is defined between the glue blocking plate 54 and the inner peripheral wall of the tank body 51 .

[0051] The technicians can also set the tank body 51 into a triangular prism, a quadrangular prism, a hexagonal prism, etc. according to the needs, and no further examples are given here.

[0052] In this embodiment, a glue blocking plate 54 is also provided. When the glue storage tank 5 moves from the top area or the upper area to the lower area of ​​the driven carrier 11, and the partition gradually changes from an inclined upward state to a horizontal state and an inclined downward state, as much glue as possible can be retained in the glue storage cavity 511, thereby reducing the risk of glue overflowing from the glue connecting port 52.

[0053] Specifically, in this embodiment, Figure 6 and Figure 7 As shown, the shape of the inner ring 121 of the static disk is circular; The size of the moving disc inner ring 111 is larger than the diameter of the static disc inner ring 121; The moving carrier plate 11 is also provided with a baffle plate for preventing the glue from flowing out of the moving plate inner ring 111, so as to ensure that the glue is located in the moving plate inner ring 111 as much as possible. In this embodiment, the end surface of the glue storage tank 5 is also provided with a detachably connected end cover to facilitate pouring the glue from the tank body 51.

[0054] The rest of the structure of this embodiment is the same as that of the above-mentioned embodiment 1 or embodiment 2, and will not be described again here.

[0055] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
