Description

Technical Field

[0001] This application relates to the field of prepreg production lines, and more particularly to a modular platform framework structure for a prepreg production line. Background Technology

[0002] Thermosetting prepreg production lines involve numerous units such as multiple unwinding and winding units, multiple pressing units, and laminating units. These various pieces of equipment are distributed across first and second-floor platforms, requiring high installation precision and strict tolerances for the parallelism and position of the guide rollers. Different users have different configurations; these are essentially customized equipment. While the basic structure of the unit machines is the same, the differences lie mainly in parameters such as roller diameter and width.

[0003] In typical production lines, individual machines are directly fixed to the ground using expansion bolts. Some lines use I-beams, first fixing them to the ground and then installing the individual machines onto them. However, the second-level platform is directly fixed to the ground using columns. This means the positional tolerances of the second-level platform cannot be guaranteed, resulting in lower installation accuracy and significantly increasing the workload for debugging.

[0004] In addition, after the pre-assembly and debugging are completed, each unit needs to be disassembled and transported to the user's factory for reassembly and debugging, which is time-consuming and labor-intensive. Utility Model Content

[0005] To facilitate assembly and improve assembly efficiency, this application provides a modular platform frame structure for a prepreg production line.

[0006] This application provides a modular platform frame structure for a prepreg production line, which adopts the following technical solution:

[0007] A modular platform frame structure for a prepreg production line includes a coating unit, multiple pressing units, and multiple take-up and unwinding units. It also includes a base and a second-level platform. The coating unit and multiple pressing units are fixed to the base, and the multiple take-up and unwinding units are fixed to the second-level platform. The outer sides of the coating unit and multiple pressing units are provided with protective wall panels. The bottom of each protective wall panel is fixed to the base, and the top of each protective wall panel is provided with a hoisting plate. The second-level platform can be detachably mounted on at least two hoisting plates.

[0008] Optionally, each of the lifting plates is provided with at least two heightening modules spaced apart along its own length.

[0009] Optionally, the lower end of the height-increasing module is provided with a lower connecting plate, and the upper end is provided with an upper connecting plate, wherein the lower connecting plate is fixedly connected to the hoisting plate.

[0010] Optionally, the lifting plate is provided with lifting rings.

[0011] Optionally, the height-increasing module includes a height-increasing screw sleeve and a height-increasing screw tube that are coaxially fixed. A connecting screw sleeve is fixed at the upper end of the lower connecting plate, and a connecting screw tube is fixed at the lower end of the upper connecting plate. The height-increasing screw tube is threadedly connected to the connecting screw sleeve, and the connecting screw tube is threadedly connected to the height-increasing screw sleeve.

[0012] Optionally, the heightening helical tube is threaded with a lower limiting ring, the bottom end of which abuts against the top end of the connecting threaded sleeve.

[0013] Optionally, the connecting screw is threaded with an upper limit ring, the bottom end of which abuts against the top end of the heightening screw sleeve.

[0014] Optionally, the outer wall of the height-increasing screw sleeve is provided with an outer reinforcing rib, and the inner wall of the height-increasing screw tube is provided with a first inner reinforcing rib.

[0015] Optionally, the outer wall of the connecting threaded sleeve is provided with a reinforcing rib, and the bottom end of the reinforcing rib is fixed to the lower connecting plate.

[0016] Optionally, the inner wall of the connecting screw tube is provided with a second reinforcing rib.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. This application integrates the laminating unit and multiple pressing units onto a single-layer base, and integrates multiple unwinding and winding units onto a second-layer platform. The second-layer platform is detachably mounted on a lifting plate. After pre-assembly and debugging, the second-layer platform can be removed, and the single-layer base and second-layer platform can be transported separately to the user's factory for assembly. Compared to disassembling each individual unit and then assembling and debugging them separately, this method saves assembly steps and improves installation efficiency.

[0019] 2. In this application, after the laminating unit and multiple pressing units on the first-layer base are modularly installed and fixed according to a preset functional sequence, the relative positions of each individual device remain relatively fixed. Similarly, the relative positions of each individual device in the multiple unwinding and winding units on the second-layer platform also remain relatively fixed. Thus, when transported to the user's factory for production line assembly, only the installation accuracy between the first-layer base and the second-layer platform needs to be ensured to guarantee the overall assembly accuracy of the production line.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail below.

[0026] Example 1:

[0027] Embodiment 1 of this application discloses a modular platform frame structure for a prepreg production line. (Refer to...) Figure 1 A modular platform frame structure for a prepreg production line includes a base 1, a platform 2, a coating unit 3, multiple pressing units 4, and multiple take-up and unwinding units 5. The coating unit 3 and the multiple pressing units 4 are fixed to the base 1, and the multiple take-up and unwinding units 5 are fixed to the platform 2. To improve safety and protect individual equipment, protective wall panels 6 are provided on the outer sides of the coating unit 3 and the multiple pressing units 4. The bottom of each protective wall panel 6 is fixed to the base 1, and the top of each protective wall panel 6 is fixed to a lifting plate 7. The platform 2 can be detachably mounted on at least two lifting plates 7.

[0028] This application integrates the laminating unit 3 and multiple pressing units 4 onto a single-layer base 1, and integrates multiple unwinding and winding units 5 onto a second-layer platform 2. The second-layer platform 2 is detachably mounted on a lifting plate 7. After pre-assembly and debugging, the second-layer platform 2 can be removed, and then the single-layer base 1 and the second-layer platform 2 can be transported separately to the user's factory for assembly. Compared to disassembling each individual unit and then assembling and debugging them separately, this saves assembly steps and improves installation efficiency.

[0029] Furthermore, after the laminating unit 3 and multiple pressing units 4 on the first-layer base 1 are modularly installed and fixed according to a preset functional sequence, the relative positions of each individual device can remain relatively fixed. Similarly, the relative positions of each individual device of the multiple unwinding and winding units 5 on the second-layer platform 2 also remain relatively fixed. Thus, when transported to the user's factory for production line assembly, only the installation accuracy between the first-layer base 1 and the second-layer platform 2 needs to be ensured to guarantee the overall assembly accuracy of the production line.

[0030] Reference Figure 1 Furthermore, the second-layer platform 2 has two installation methods. For narrow production lines, the second-layer platform 2 occupies less space and can be directly erected and fixed on the lifting plates 7 on top of two adjacent protective wall panels 6. It can be transported as a whole without dismantling. For wide production lines or when users need to reserve some space on the second-layer platform 2 for future expansion and renovation plans, each lifting plate 7 is equipped with at least two height-increasing modules 8 spaced apart along its own length. When using this installation method, the second-layer platform 2 occupies more space and needs to be dismantled for transportation. Moreover, since the actual height of each individual device on the first-layer base 1 is not consistent, the height of each protective wall panel 6 is also inconsistent. The height-increasing modules 8 can be used to adjust the height of each protective wall panel 6, which helps to compensate for the height difference between the protective wall panels 6, thereby ensuring that the platform surface of the second-layer platform 2 is in a horizontal position.

[0031] Reference Figure 1 The lower end of the height-increasing module 8 is fixed with a lower connecting plate 82, and the upper end is fixed with an upper connecting plate 81. The lower connecting plate 82 is fixed to the lifting plate 7 with bolts. In this way, the height-increasing module 8 is fixed to the lifting plate 7 through the lower connecting plate 82, and can be fixed to the second-level platform 2 through the upper connecting plate 81. This facilitates the flexible disassembly, assembly, and replacement of the height-increasing module 8, improving the assembly flexibility of the production line.

[0032] Reference Figure 1 To facilitate the overall transportation of the first-floor base 1, a lifting ring 71 is fixed to the top of the lifting plate 7. By connecting the hook or rope of the crane or other lifting equipment to the lifting ring 71, the first-floor base 1 can be lifted as a whole.

[0033] Example 2:

[0034] Embodiment 2 of this application discloses a modular platform frame structure for a prepreg production line. (Refer to...) Figure 2The difference between this second embodiment and the first embodiment is that the height-increasing module 8 includes a coaxial and integrally formed height-increasing sleeve 83 and a height-increasing tube 84. A connecting sleeve 821 is fixed to the upper end of the lower connecting plate 82, and a connecting tube 812 is fixed to the lower end of the upper connecting plate 81. The height-increasing tube 84 is threadedly connected to the connecting sleeve 821, and the connecting tube 812 is threadedly connected to the height-increasing sleeve 83. Compared to the fixed height of each height-increasing module 8 in the first embodiment, the height of the height-increasing module 8 in the second embodiment is adjustable. Therefore, the height of the second-floor platform 2 can be adjusted according to the specific spatial layout of the user's factory, thereby improving the flexibility of the second-floor platform 2 construction. This facilitates adaptive adjustments based on the actual vertical height of the user's factory and allows for subsequent adjustments to the production space layout, enhancing flexibility.

[0035] Reference Figure 2 To minimize the possibility of changes in the height of the height-adjusting module 8 during use, a lower limit ring 841 is threaded onto the height-adjusting screw tube 84, with its bottom end abutting against the top end of the connecting screw sleeve 821; an upper limit ring 8121 is threaded onto the connecting screw tube 812, with its bottom end abutting against the top end of the height-adjusting screw sleeve 83. After height adjustment, the lower limit ring 841 keeps the connecting screw sleeve 821 and the height-adjusting screw tube 84 relatively fixed, and the upper limit ring 8121 keeps the height-adjusting screw sleeve 83 and the connecting screw tube 812 relatively fixed, thereby ensuring the stability of the height of the height-adjusting module 8.

[0036] Reference Figure 2-4 To ensure the structural strength of the height-increasing module 8 in Embodiment 2 and improve its load-bearing capacity, the outer wall of the height-increasing screw sleeve 83 is integrally formed with an outer reinforcing rib 831; the inner wall of the height-increasing screw tube 84 is integrally formed with a first inner reinforcing rib 842; the inner wall of the connecting screw tube 812 is integrally formed with a second inner reinforcing rib 8122; and a reinforcing rib plate 822 is fixed to the outer wall of the connecting screw sleeve 821, with the bottom end of the reinforcing rib plate 822 fixed to the lower connecting plate 82.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
