Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a roll wrapping device and method for cylindrical components. Background Technology

[0002] In the construction industry, wooden columns are commonly used as load-bearing components, primarily resisting axial pressure. To enhance the axial compressive load-bearing capacity of wooden columns, they are typically wrapped with carbon fiber cloth to provide circumferential restraint. The process involves first cutting the carbon fiber cloth, then securing one end of the cloth to the wooden column with quick-drying adhesive. Next, adhesive is applied to the cloth, and then one person tensions the cloth while another rotates the wooden column to wrap it around the column.

[0003] The above procedures are cumbersome and require at least two people to work together. They are complex and inefficient. Moreover, the tension of the carbon fiber cloth during the wrapping process has a significant impact on the load-bearing capacity of the component. The tension of the carbon fiber cloth in the above procedures is felt and controlled by people, making it difficult to control the tension of the carbon fiber cloth during the wrapping process and thus failing to guarantee the bonding quality of the carbon fiber cloth. Summary of the Invention

[0030] The advantages of the roll wrapping device and method for cylindrical components according to embodiments of the present invention compared with the prior art are as follows:

[0031] This invention discloses a roll wrapping device and method for cylindrical components. The cylindrical component is clamped and fixed using an adjusting component of a positioning structure and a torque sensor-type motor. The roll material is then sequentially wound around an unwinding roller, multiple conveying rollers, and the cylindrical component. The torque sensor-type motor drives the cylindrical component to rotate, thereby conveying the roll material and wrapping it around the component surface. A torque motor is installed at the unwinding roller to apply torque to the roll material. The torque sensor-type motor measures the tension of the roll material on the cylindrical component, ensuring that the tension applied by the torque motor meets the preset tension requirements, thus ensuring that the bonding quality of the roll material meets the design requirements of the cylindrical component.

[0040] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0042] It should be understood that the terms "first," "second," etc., are used in this invention to describe various types of information, but these terms are not limited to them; they are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0043] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] like Figure 1 As shown, a preferred embodiment of the present invention provides a roll wrapping device for cylindrical components, comprising a fixed frame 1, an unwinding roller 2 rotatably mounted at one end of the fixed frame 1, and a torque motor 3 for driving the unwinding roller 2 to rotate on the fixed frame 1; each conveying roller 4 is rotatably mounted in the middle of the fixed frame 1; an operating table 5 is located in the middle of the fixed frame 1 and is used to store adhesive; a scraping adhesive mechanism 6 is fixedly mounted on the fixed frame 1; and a positioning mechanism 7 includes an adjusting component 7a and a torque sensor motor 7b, which are used for detachably positioning the cylindrical component. One end of the cylindrical component abuts against the output end of the torque sensor motor 7b, and the other end of the cylindrical component abuts against the adjusting component 7a. The adjusting component 7a is used to adjust the clamping force required to clamp the cylindrical component, and the torque sensor motor 7b is used to drive the cylindrical component to rotate.

[0045] Among them, at least one conveying roller 4 near the operating table 5 has a gap reserved between it and the operating table 5 for the passage of the roll material. Along the roll material conveying direction, the roll material is sequentially wound around the unwinding roller 2, multiple conveying rollers 4 and cylindrical components.

[0046] In this process, the roll material passes through the gap, so that the adhesive on the operating table 5 is applied to the roll material, and the scraper of the adhesive scraping mechanism 6 is attached to the roll material after the adhesive is applied.

[0047] This invention discloses a roll wrapping device and method for cylindrical components. The cylindrical component is clamped and fixed by an adjusting member 7a of a positioning structure 7 and a torque sensor motor 7b. The roll material is then sequentially wound around an unwinding roller 2, multiple conveying rollers 4, and the cylindrical component. The torque sensor motor 7b drives the cylindrical component to rotate, thereby conveying the roll material and wrapping it around the component surface. A torque motor 3 is installed at the unwinding roller 2 to apply torque to the roll material. The torque sensor motor 7b measures the tension of the roll material on the cylindrical component, ensuring that the tension applied by the torque motor 2 meets the preset tension requirements, thus ensuring that the bonding quality of the roll material meets the design requirements of the cylindrical component. Multiple conveying rollers 4 are installed in the middle of the fixing frame 1 to support and convey the roll material, keeping it stable during conveying and avoiding problems such as uneven adhesive application or loose wrapping caused by roll material swaying. The fixing frame 1 is also equipped with an operating table 5, and an adhesive scraping mechanism 6 is installed on the upper part of the operating table 5. When the roll material passes through the operating table 5, adhesive is applied to the roll material. When it passes through the adhesive scraping mechanism 6, the adhesive scraping mechanism 6 scrapes the adhesive evenly on the roll material, avoiding adhesive accumulation or gaps, thereby improving the adhesion between the roll material and the cylindrical component. In addition, the adjusting member 7a in the positioning mechanism 7 can adjust the clamping force to adapt the positioning mechanism 7 to different cylindrical components, improving the versatility and flexibility of the wrapping device.

[0048] The embodiments of the present invention are simple and convenient to operate, with a high degree of automation. They not only improve work efficiency but also save a lot of manpower, avoid the impact of human factors on work quality, and solve the technical problems in the prior art where the process of wrapping wooden columns with carbon fiber cloth is complicated and inefficient, and it is difficult to control the tension of the carbon fiber cloth during the wrapping process, thus failing to guarantee the bonding quality of the carbon fiber cloth.

[0049] Specifically, such as Figure 1 As shown, in this embodiment of the invention, the fixing frame 1 includes a horizontally arranged base plate 1a and vertical plates 1b fixed to both sides of the base plate 1a. Both the base plate 1a and the vertical plates 1b are made of steel plates, and the vertical plates 1b are welded and fixed to the base plate 1a.

[0050] Furthermore, such as Figure 1 and Figure 4 As shown, a unwinding roller 2 is provided at the front end of the fixed frame 1 for unwinding the roll material. In order to meet the pre-tension requirements when wrapping the roll material, the right end of the unwinding roller 2 is rotatably connected to the vertical plate 1b through a rotating shaft bearing. A torque motor 3 is provided on the outside of the vertical plate 1b at the left end of the unwinding roller 2. The output shaft of the torque motor 3 passes through the vertical plate 1b and enters the fixed frame 1, and is detachably fixedly connected to the left end of the unwinding roller 2.

[0051] In order to achieve a detachable and fixed connection between the left end of the unwinding roller 2 and the output shaft of the torque motor 3, such as... Figure 4 and Figure 5As shown, the roll wrapping device for cylindrical components also includes a pin 11. The output shaft of the torque motor 3 has a notch at its end, and one end of the unwinding roller 2 has a connecting part that matches the notch. Both the output shaft at the notch and the connecting part have corresponding second pin holes. The pin 11 can be detachably passed through three second pin holes to allow the unwinding roller 2 and the output shaft of the torque motor 3 to be detachably and fixedly connected. Before unwinding, the torque motor 3 can be started to drive the unwinding roller 2 to rotate and wind the roll material onto the unwinding roller 2. Alternatively, the pin 11 at the connection between the unwinding roller 2 and the output shaft of the torque motor 3 can be pulled out, the unwinding roller 2 removed, the roll material wound onto the unwinding roller 2, and then the unwinding roller 2 with the wound roll material reinstalled.

[0052] Furthermore, such as Figure 1 and Figure 3 As shown, multiple conveying rollers 4 are arranged in the middle of the fixed frame 1, and the two ends of each conveying roller 4 are rotatably connected to the fixed frame 1 through a rotating shaft bearing. In this embodiment of the invention, there are 4 conveying rollers 4, of which 2 are arranged between the unwinding roller 2 and the operating table 5, 1 is arranged between the positioning mechanism 7 and the operating table 5 for supporting and transporting the roll material, and the remaining 1 is arranged above the operating table 5, with a gap reserved between it and the operating table 5 for the roll material to pass through. When the roll material moves through this gap, the glue on the operating table 5 is applied to the roll material.

[0053] Furthermore, such as Figure 1 and Figure 3 As shown, the operating table 5 is located in the middle of the base plate 1a of the fixed frame 1 and is used to store adhesive. The operating table 5 includes a first table surface 5a inclined downwards along the roll material conveying direction and a second table surface 5b inclined upwards along the roll material conveying direction. The lower ends of the first table surface 5a and the second table surface 5b are fixedly connected. A conveying roller 4 is provided above the connection between the first table surface 5a and the second table surface 5b, forming a gap for the roll material to pass through. The adhesive is stored in the groove formed by the first table surface 5a and the second table surface 5b. To enhance the stability of the first table surface 5a and the second table surface 5b mounted on the fixed frame 1, a connecting plate 12 is vertically provided at the front and rear ends of the operating table 5, respectively. The upper and lower ends of the connecting plate 12 are fixedly connected to the base plate 1a and each table surface of the operating table 5. In this embodiment of the invention, the first table surface 5a, the second table surface 5b, and the connecting plate 12 are directly bent from steel plates and fixedly connected by welding when mounted on the fixed frame 1.

[0054] Furthermore, such as Figure 1 and Figure 3As shown, to ensure even application of adhesive on the roll material, a scraping mechanism 6 is provided in the middle of the frame 1. The scraping mechanism 6 includes a scraper seat 6a and a scraper 6b fixedly connected to the scraper seat 6a. The scraper seat 6a is fixedly connected to the frame 1, and the edge of the scraper 6b abuts against the surface of the roll material. In this embodiment, the scraping mechanism 6 is positioned on the second surface 5b of the operating table 5, with the scraper 6b placed perpendicular to the second surface 5b. To facilitate replacement of the scraper 6b after wear, both the end of the scraper seat 6a and the frame 1 are provided with first pin holes. A fixing pin can be detachably passed through both first pin holes to detachably fix the scraper seat 6a to the frame 1.

[0055] Furthermore, such as Figure 1 and Figure 2 As shown, a positioning mechanism 7 is provided at the rear end of the fixing frame 1. The positioning mechanism 7 includes an adjusting component 7a and a torque sensor motor 7b. The adjusting component 7a and the torque sensor motor 7b are used to detachably position the cylindrical component, and the adjusting component 7a is used to adjust the clamping force required to clamp the cylindrical component. The adjusting component 7a includes an outer ring bearing 71a, an inner ring bearing 72a, and a lead screw 73a. The outer ring bearing 73a is fixedly connected to the fixing frame 1, and the outer ring bearing 71a is rotatably connected to the inner ring bearing 72a. In this embodiment of the invention, the outer ring bearing 71a and the inner ring bearing 72a can be directly selected as crossed roller bearings. The crossed roller bearing includes the outer ring bearing 71a and the inner ring bearing 72a that are rotatably connected. During installation, the outer periphery of the crossed roller bearing is fixedly connected to the vertical plate 1b of the fixing frame 1.

[0056] A lead screw 73a extends horizontally through an inner ring bearing 72a, which is threadedly connected to the lead screw 73a. A support 9 is fixedly installed on the side of the lead screw 73a near the cylindrical component. The support 9 is spaced apart from the output end of the torque sensor motor 7b, and both ends of the cylindrical component abut against the support 9 and the output end of the torque sensor motor 7b, respectively. In this embodiment of the invention, the support 9 is a rubber support, which is threadedly fixed to the end of the lead screw 9.

[0057] Furthermore, the adjusting member 7a also includes a bearing pin that can be detachably inserted into both the outer ring bearing 71a and the inner ring bearing 72a. In this embodiment of the invention, the bearing pin is a U-shaped rod 74a. The surfaces of both the outer ring bearing 71a and the inner ring bearing 72a of the crossed roller bearing are provided with multiple circular holes spaced apart along their circumference. When the lead screw 73a needs to move horizontally relative to the vertical plate 1b of the fixing frame 1, the inner ring bearing 72a needs to be fixed to restrict its rotation. Therefore, the two ends of the U-shaped rod 74a are inserted into the circular holes on the surfaces of the outer ring bearing 71a and the inner ring bearing 72a, respectively, so that the inner ring bearing 72a is fixedly connected to the outer ring bearing 71a, and the inner ring bearing 72a cannot rotate. After the cylindrical component is fixed, when the torque sensor motor 7b drives the cylindrical component to rotate and wrap the roll material, the U-shaped rod 74a is pulled out, causing the inner ring bearing 72a to rotate together with the torque sensor motor 7b.

[0058] Furthermore, such as Figure 2 As shown, to facilitate the rotation of the lead screw 73a, a handle 10 is fixedly provided at the end of the lead screw 73a away from the support 9. In this embodiment of the invention, the handle 10 is a wooden handle and is threadedly connected to the end of the lead screw 73a.

[0059] In this embodiment of the invention, the lead screw 73a can be adjusted and replaced according to the length of different cylindrical components. When replacing the lead screw 73a, firstly, the support 9 at the end of the lead screw 73a is rotated and removed. Then, the two ends of the U-shaped rod 74a are respectively inserted into the round holes of the outer ring bearing 71a and the inner ring bearing 72a. Then, the lead screw 73a is rotated to remove it from the inner ring bearing 72a. Then, the handle 10 at the other end of the lead screw 73a is rotated and removed. Then, a new lead screw 73a is replaced and the handle 10 is installed at the end of the lead screw 73a. Then, the lead screw 73a is rotated forward along the thread inside the inner ring bearing 72a. Finally, the support 9 is rotated and installed at the end of the lead screw 73a.

[0060] Furthermore, such as Figure 1 As shown, to facilitate cutting the roll material, a slicing rail 8 is provided between the operating table 5 and the positioning mechanism 7. The slicing rail 8 is fixedly installed on the fixing frame 1 and is used to cut the roll material. In this embodiment of the invention, the slicing rail 8 is made of steel strips, with both ends of the steel strips fixedly connected to the vertical plates 1b of the fixing frame 1. The steel strips are provided with grooves extending along their length, which are the tracks for the slicing blade to pass through. After the roll material of the cylindrical component is wrapped, the slicing blade is used to cut the roll material by slicing across the slicing rail 8, and then the last section of roll material is manually pasted onto the surface of the cylindrical component.

[0061] like Figures 1 to 4 As shown, an embodiment of a method for wrapping a cylindrical component with a roll material includes the following steps:

[0062] S1. Along the coil conveying direction, the coil is sequentially wound around the unwinding roller 2, multiple conveying rollers 4 and cylindrical components;

[0063] In S1, the roll material is first wound onto the unwinding roller 2. The unwinding roller 2 can be removed by pulling out the pin 11 to unwind the roll material, or the unwinding roller 2 can be driven to rotate and wind the roll material by using the torque motor 3. Then, the U-shaped rod 74a is inserted into the outer ring bearing 71a and the inner ring bearing 72a, and then the handle 10 is turned to make the lead screw 73a move the support 9 closer to and clamp the cylindrical component. After the roll material is wound onto the unwinding roller 2 and the cylindrical component is fixed, the roll material is then wound onto the unwinding roller 2, multiple conveying rollers 4 and the cylindrical component in sequence according to the designed conveying route.

[0064] S2. Adjust the output torque of the torque motor 3 and read the torque measured by the torque sensor motor 7b. Calculate the tension of the roll material using this torque to make the tension reach the preset tension range of the roll material.

[0065] In S2, the torque motor 3 is used to apply and gradually increase the output torque, while the torque reading of the torque sensor motor 7b is observed. The tension force is calculated based on the obtained torque reading. This tension force is the tension force when the roll material is wrapped on the cylindrical component. When the tension force of the roll material reaches the designed tension force, the torque motor 3 is stopped from being adjusted. The current output torque of the torque motor is the stall torque required for subsequent tensioning of the roll material.

[0066] S3. Pour glue onto the worktable 5, and apply the glue from the worktable 5 onto the roll as it passes through the gap.

[0067] In S3, the operating table 5 includes a first table surface 5a inclined downward along the roll material conveying direction and a second table surface 5b inclined upward along the roll material conveying direction. The lower end of the first table surface 5a is fixedly connected to the lower end of the second table surface 5b. A conveying roller 4 is provided above the connection between the first table surface 5a and the second table surface 5b, forming a gap for the roll material to pass through. After applying glue to the roll material behind the cylindrical member and the glue scraping mechanism 6, the glue is poured into the groove formed by the first table surface 5a and the second table surface 5b on the operating table 5. When the roll material passes through this gap, the glue is applied to the roll material.

[0068] S4, Torque sensor type motor 7b drives the cylindrical component to rotate;

[0069] In S4, the U-shaped rod 74a is pulled out and the torque sensor motor 7b is started to drive the cylindrical component to rotate. The roll material is wrapped around its surface as the cylindrical component rotates. At this time, the torque motor 3 is in a stalled state. The output shaft of the torque motor 3 is driven by the roll material to rotate in the opposite direction, that is, it rotates in the opposite direction of the torque output direction of the torque motor 3.

[0070] S5, the glue scraping mechanism 6 scrapes the glue on the roll material evenly;

[0071] In step S5, the adhesive application mechanism 6 includes a scraper seat 6a and a scraper 6b fixedly connected to the scraper seat 6a. The scraper seat 6a is fixedly connected to the fixing frame 1, and the edge of the scraper 6b abuts against the surface of the roll material. In this embodiment of the invention, the adhesive application mechanism 6 is disposed on the second table surface 5b of the operating table 5, and the scraper 6b is placed perpendicular to the second table surface 5b. To facilitate the replacement of the scraper 6b after wear, both the end of the scraper seat 6a and the fixing frame 1 are provided with first pin holes. The fixing pin can be detachably passed through both first pin holes to detachably fix the scraper seat 6a to the fixing frame 1. When the roll material passes through the scraper 6b, the scraper 6b evenly spreads the adhesive on the surface of the roll material, realizing the automatic adhesive application operation of the roll material.

[0072] S6. Roll material wrapping of cylindrical components.

[0073] In S6, after the roll of material for the cylindrical component is wrapped, the roll is cut by slicing along the slicing rail 8 with a slicing knife. Then, the last section of roll material is manually pasted onto the surface of the cylindrical component. Subsequently, the U-shaped rod 74a is inserted into the outer ring bearing 71a and the inner ring bearing 72a. The handle 10 is rotated to loosen the contact between the bracket 9 and the cylindrical component, and the cylindrical component with the rolled material wrapped is removed.

[0074] The working process of this invention is as follows: First, the roll material is wound on the unwinding roller 2. The unwinding roller 2 can be removed by pulling out the pin 11 to remove the roll material, or the unwinding roller 2 can be driven to rotate and wind the roll material by using the torque motor 3. Then, the U-shaped rod 74a is inserted into the outer ring bearing 71a and the inner ring bearing 72a. Then, the handle 10 is turned so that the lead screw 73a drives the support 9 to approach and clamp the cylindrical component. After the roll material is wound on the unwinding roller 2 and the cylindrical component is fixed, the roll material is wound on the unwinding roller 2, multiple conveying rollers 4 and the cylindrical component in sequence according to the designed conveying route.

[0075] Then, the torque motor 3 is used to apply and gradually increase the output torque, while the torque reading in the torque sensor motor 7b is observed. The tension force is calculated based on the obtained torque reading. This tension force is the tension force when the roll material is wrapped on the cylindrical component. When the tension force of the roll material reaches the designed tension force, the torque motor 3 is stopped from being adjusted. The current output torque of the torque motor is the stall torque required for subsequent tensioning of the roll material.

[0076] Next, the adhesive is evenly applied to the cylindrical component and the roll material after the adhesive scraping mechanism 6. Then, the adhesive is poured into the groove formed by the first table surface 5a and the second table surface 5b on the operating table 5. As the roll material passes through the gap, the adhesive is applied to the roll material. Then, the U-shaped rod 74a is pulled out, and the torque sensor motor 7b is started to drive the cylindrical component to rotate. The roll material is conveyed and wrapped around its surface as the cylindrical component rotates.

[0077] As the roll material passes through the scraper 6b, the scraper 6b evenly spreads the adhesive on the roll material surface, achieving automatic adhesive application. After the roll material is wrapped around the cylindrical component, the roll material is cut by slicing along the slicing rail 8. Then, the last section of roll material is manually pasted onto the surface of the cylindrical component. Subsequently, the U-shaped rod 74a is inserted into the outer ring bearing 71a and the inner ring bearing 72a, and the handle 10 is rotated to loosen the contact between the bracket 9 and the cylindrical component, allowing the rolled cylindrical component to be removed.

[0078] In summary, the present invention provides a roll wrapping device and method for cylindrical components. The cylindrical component is clamped and fixed using an adjusting component of the positioning structure and a torque sensor motor. The roll material is then sequentially wound around an unwinding roller, multiple conveying rollers, and the cylindrical component. The torque sensor motor drives the cylindrical component to rotate, thereby conveying the roll material and wrapping it onto the component surface. A torque motor is installed at the unwinding roller to apply torque to the roll material. The torque sensor motor measures the tension of the roll material on the cylindrical component, ensuring that the tension applied by the torque motor meets the preset tension requirements, thus ensuring that the bonding quality of the roll material meets the design requirements of the cylindrical component. Multiple conveying rollers are located in the middle of the fixing frame to support and convey the roll material, keeping it stable during conveying and avoiding problems such as uneven adhesive application or loose wrapping caused by roll material swaying. The fixed frame is also equipped with an operating table, and a glue scraping mechanism is installed on the upper part of the operating table. When the roll material passes through the operating table, glue is applied to the roll material. When it passes through the glue scraping mechanism, the glue scraping mechanism scrapes the glue on the roll material evenly, avoiding glue accumulation or missing glue, thereby improving the adhesion between the roll material and the cylindrical component.

[0079] Furthermore, the adjusting element in the positioning mechanism allows for adjustment of the clamping force, enabling the positioning mechanism to adapt to different cylindrical components, thus improving the versatility and flexibility of the wrapping device. A scribing rail is installed in the middle of the fixed frame, greatly simplifying the operation of cutting the roll material; the adhesive scraping mechanism is detachably fixed to the fixed frame via a fixing pin, further simplifying the scraper replacement process; in addition, the torque motor output end is detachably fixed to the unwinding roller via a pin, allowing the unwinding roller to be easily removed for roll material installation, further enhancing the ease of roll material installation.

[0080] The embodiments of the present invention are simple and convenient to operate, with a high degree of automation. They not only improve work efficiency but also save a lot of manpower, avoid the impact of human factors on work quality, and solve the technical problems in the prior art where the process of wrapping wooden columns with carbon fiber cloth is complicated and inefficient, and it is difficult to control the tension of the carbon fiber cloth during the wrapping process, thus failing to guarantee the bonding quality of the carbon fiber cloth.

[0081] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
