Description

Technical Field

[0001] The present application relates to the technical field of uncoiling equipment, and in particular to a glass fiber reinforced plastic uncoiling machine. Background Art

[0002] FRP is widely used due to its lightweight, high-strength, corrosion-resistant, and excellent thermal performance. Currently, there are two main methods for unwinding FRP: one is to manually pull the material, which is difficult to operate, labor-intensive, and poses a high risk of safety hazards. The other method uses a motor to drive a reducer to rotate the drive reel core, and the FRP coil is inserted into the drive reel core through a hollow position. This method drives the FRP coil to rotate to unwind. This method requires a crane to load and unload the FRP coil, which places high demands on workshop infrastructure, equipment costs, and energy consumption.

[0003] Therefore, for the uncoiling operation of glass fiber reinforced plastics, how to simplify the manual operation, ensure safety and reduce costs is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0026] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Due to the characteristics of FRP such as light weight, high strength, high corrosion resistance and good thermal performance, it is widely used. This embodiment provides a FRP uncoiler for uncoiling a FRP coil 5, wherein the FRP coil 5 is a roll structure formed by rolling a FRP plate 51. The FRP uncoiler can unwind the FRP coil 5 to form a FRP plate 51. Figure 1 As shown, the FRP uncoiler includes a discharge device 2 and a pulling device 1, wherein the discharge device 2 includes a discharge shaft 21, the discharge shaft 21 is used to place the FRP coil 5, and the pulling device 1 is used to provide tension to the FRP so that the FRP coil 5 rotates around the discharge shaft 21 and realizes uncoil.

[0028] Specifically, such as Figure 2 As shown, the pulling device 1 includes a driving member, a bracket 11 and a roller assembly, wherein the roller assembly is arranged on the bracket 11, and the roller assembly includes an upper roller 12 and a lower roller 13 arranged in parallel, the upper roller 12 is located above the lower roller 13, and the glass fiber reinforced plastic plate 5 can pass through the gap between the roller 12 and the lower roller 13, and the upper roller 12 and the lower roller 13 can clamp the glass fiber reinforced plastic plate 51 from the upper and lower sides respectively, so that the glass fiber reinforced plastic plate 51 is in a clamped state between the two.

[0029] The drive member is used to rotate the upper roller 12, the lower roller 13, or both. The friction between the surfaces of the rollers (the upper roller 12 and / or the lower roller 13) and the fiberglass sheet 51 pulls the fiberglass sheet 51, causing the fiberglass coil 5 to rotate about the unwinding shaft 21. The surfaces of the upper roller 12 and / or the lower roller 13 and the fiberglass sheet 51 both utilize rolling friction, resulting in a simple and reliable structure with minimal impact on the appearance and quality of the fiberglass coil 5.

[0030] Pulling the fiberglass sheet 51 to unwind the sheet using the pulling device 1 reduces labor intensity, simplifies the unwinding operation, and mitigates safety hazards. Furthermore, the upper and lower rollers 12 and 13, combined with the driving action of the drive element, provide pulling force, resulting in a simple overall structure, minimal requirements for workshop infrastructure, low equipment costs, and excellent economic efficiency.

[0031] like Figure 2 As shown, the FRP uncoiler further includes a connecting member 14 and an adjusting member 15, wherein the upper roller 12 is disposed on the connecting member 14, and the adjusting member 15 is disposed between the connecting member 14 and the bracket 11 and is used to adjust the spacing between the upper roller 12 and the lower roller 13, so that the upper roller 12 and the lower roller 13 can clamp the FRP sheet 51 from the upper and lower sides, respectively. Of course, in this embodiment, the connecting member 14 can also be directly fixed to the bracket 11, and the relative position of the upper roller 12 and the lower roller 13 cannot be adjusted. When the relative position of the upper roller 12 and the lower roller 13 can be adjusted by the adjusting member 15, the FRP uncoiler can be adapted to uncoil FRP sheets 51 of different thicknesses, and has good flexibility.

[0032] Specifically, a bearing is provided between the upper roller 12 and the connecting member 14, and a bearing is also provided between the lower roller 13 and the bracket 11 to ensure smooth rotation of the upper roller 12 and the lower roller 13 and avoid jamming.

[0033] Furthermore, in this embodiment, the adjusting member 15 is an elastic adjusting member 15. It is not difficult to understand that the elastic adjusting member 15 has a certain elasticity. The elastic adjusting member 15 can act between the connecting member 14 and the bracket 11. The setting of the elastic adjusting member 15 can ensure that after adjustment, the relative position between the upper roller 12 and the lower roller 13 still has a certain elasticity. In this way, while ensuring that the upper roller 12 and the lower roller 13 clamp the fiberglass plate 51, it can avoid damage to the equipment or the fiberglass plate 51 due to rigidity.

[0034] Specifically, the elastic adjustment member 15 includes a spring 151, a screw 152, and a nut 153. One end of the screw 152 is fixed to the bracket 11, while the other end passes through the connector 14 and engages with the nut 153. The spring 151 is sleeved around the screw 152 and sandwiched between the bracket 11 and the nut 153. Specifically, the spacing between the connector 14 and the bracket 11 can be adjusted by rotating the nut 153, thereby adjusting the gap between the upper roller 12 and the lower roller 13 to ensure that the upper roller 12 and the lower roller 13 can clamp the fiberglass reinforced plastic sheet 51 from both the upper and lower sides. Alternatively, one end of the screw 152 can be fixed to the connector 14, while the other end passes through the bracket 11 and engages with the nut 153, with the spring 151 sandwiched between the connector 14 and the nut 153.

[0035] There are two upper rollers 12 and two lower rollers 13. The two upper rollers 12 are arranged at intervals on the connecting piece 14, and the two upper rollers 12 are respectively arranged above the two lower rollers 13. That is to say, there is an upper roller 12 above each lower roller 13. If an upper roller 12 and a lower roller 13 form a group, the two groups of rollers are arranged at intervals, and the fiberglass plate 51 passes through the two groups of rollers in sequence and is unfolded.

[0036] The adjusting member 15 is located between the two upper rollers 12 and is connected to the bracket 11. It is not difficult to understand that the connecting member 14 is located at both ends of the axial length of the upper roller 12, and an adjusting member 15 is respectively provided between each side and the bracket 11. Such an arrangement can ensure the adjustment stability of the adjusting member 15. Specifically, the connecting member 14 can be an integral structure, and the two upper rollers 12 can be rotatably arranged on the connecting member 14. The connecting member 14 can also be a structure including two parts, which are respectively located at both ends of the upper roller 12, and each part is respectively connected to the two upper rollers 12.

[0037] The FRP uncoiler also includes a length measuring device (not shown), which is mounted on the support 11 and located between the two lower rollers 13. The device is used to measure the length of the FRP sheet 51. Since the FRP sheet 51 is in a straightened state between the two sets of rollers, measuring the length of the FRP sheet 51 here ensures accurate measurement.

[0038] In this embodiment, the driving member includes a motor, a sprocket 16, and a chain 17. The motor and the sprocket 16 are in driving connection, and the chain 17 is respectively engaged with the sprocket 16 and the lower drum 13. The motor drives the sprocket 16 to rotate, and the chain 17 drives the lower drum 13 to rotate, thereby providing power for pulling the glass fiber reinforced plastic sheet 51. Alternatively, in this embodiment, the driving member can be configured as a structure including a motor, a drive wheel, and a belt, wherein the motor drives the drive wheel to rotate, and the belt drives the lower drum 13 to rotate.

[0039] Alternatively, the chain 17 or the belt can also drive the upper roller 12 to rotate, and no specific limitation is made here. When the chain 17 or the belt drives the lower roller 13 to rotate, it is convenient for the overall arrangement of the driving member.

[0040] like Figure 3 As shown, the unloading device 2 further includes a support frame 22 and two support rollers 23. The two support rollers 23 are rotatably mounted on the support frame 22 and are located below the unloading shaft 21 to support the FRP coil 5. Alternatively, in this embodiment, only the unloading shaft 21 may be provided, and the FRP coil 5 may be sleeved thereon. The support rollers 23 provide support for the FRP coil 5. This reduces the requirements for the unloading shaft 21 and simplifies the overall structure of the unloading device 2.

[0041] Because the FRP sheet 51 has a low elastic modulus and low shear strength, its surface is easily scratched. Therefore, a rubber layer is provided on the surface of each roller (including the upper roller 12, the lower roller 13, and the support roller 23) to protect the surface of the FRP sheet 51 and prevent damage to the surface. The provision of the rubber layer also increases the friction between the lower roller 13 and the FRP sheet 51.

[0042] like Figure 1 As shown, the FRP uncoiler further includes a shearing mechanism 4 and a material spreading platform 3. The shearing mechanism 4 includes an upper cutting die 41 and a lower cutting die 42 for cutting the FRP sheet 51. The material spreading platform 3 is disposed between the pulling device 1 and the shearing mechanism 4. The material spreading device can provide support for the pulled FRP sheet 51, facilitating subsequent cutting operations. Specifically, the shearing mechanism 4 can be a common hydraulic shearing machine, which shears the FRP sheet 51 by shearing the upper cutting die 41 and the lower cutting die 42.

[0043] In this embodiment, the FRP uncoiler further includes a display screen and a controller. The controller is connected to the drive element and the length measuring device, respectively. Specifically, the controller controls the drive element based on the length measured by the length measuring device, thereby ensuring a uniform linear speed for the FRP sheet 51 during the uncoiling process, facilitating subsequent operations such as cutting the uncoiled FRP sheet 51. The display screen can be used to display various parameters during the uncoiling process, such as the length of the FRP sheet 51 measured by the length measuring device and the uncoiling time. The display screen can also be a touch screen and used for programming and opening and closing the drive element and shearing mechanism 4.

[0044] Specifically, the required material pulling length and shearing quantity can be set through the touch screen and controller, the speed and rotation amount of the lower roller 13 can be controlled by the motor, and the length of the closed loop material pulling can be detected by the length measuring device. When the material pulling length reaches the required material length, the controller sends a signal to the shearing mechanism 4 to enable the shearing mechanism 4 to realize shearing and unloading. After cutting the required number of materials, the system automatically enters the next unwinding and unloading operation with the set length and quantity of the glass fiber reinforced plastic plate 51.

[0045] In other words, the FRP uncoiler provided in this embodiment achieves automatic uncoiling and shearing of the FRP coil 5 while reducing investment costs, reducing personnel input and labor intensity, and improving production efficiency. Furthermore, it utilizes a simple and reliable controller and motor, and achieves closed-loop control of the uncoiling material size through a length measurement device, thus reducing investment costs for automation equipment.

[0046] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
