Description

Technical Field

[0001] This utility model relates to the technical field of equipment for fiber profile forming, and in particular to a cutting and blanking equipment for fiber-reinforced polyurethane profiles. Background Technology

[0002] The molding process for fiber-reinforced resin composite profiles uses fiber yarn, resin, and felt as raw materials. The fiber yarn is impregnated with resin and then fed into a heated molding die along with the felt. The profiles are then produced through a pultrusion and heat curing process, followed by traction and cutting into finished lengths. To facilitate fixed-length cutting, cutting equipment has been developed. However, existing cutting equipment can only handle single profiles, requiring a separate employee for handling, which is time-consuming and labor-intensive.

[0003] This utility model, authorized by announcement number CN221233132U, discloses a fiber-reinforced composite profile cutting and blanking device, comprising: a support; a cutting device slidably connected to the support; a guide assembly mounted on the support on the feeding side of the cutting device; and a blanking conveyor disposed on the discharge side of the cutting device, slidably connected to the support, and fixedly connected to the cutting device via a connector. When the cutting device slides along the support, the blanking conveyor slides synchronously. The blanking conveyor is equipped with a positioning component that can move along its conveying direction. This utility model can perform fixed-length cutting of fiber-reinforced resin composite profiles, and after the profiles are cut, they can be automatically unloaded by the blanking conveyor. However, this device can only transport and unload single profiles after cutting; it cannot accumulate the cut profiles together before unloading. Utility Model Content

[0028] Cutting platform 1;

[0029] Lower cutting component 3, which is movable up and down and connected within the cutting platform 1;

[0030] A clamping structure 6 is installed on the upper side of the lower cutting assembly 3;

[0031] The movable structure 7 is mounted on the cutting platform 1 on the right side of the lower cutting assembly 3;

[0034] The feeding conveyor is equipped with a flipping component for feeding the cut profiles, and the feeding and discharging sides of the pressing structure 6 are both equipped with guide and limiting plates 9.

[0035] Specifically, the lower cutting component 3, the clamping structure 6, and the moving structure 7 constitute a cutting device. The specific structure and working principle of the cutting device are existing technologies. For details, please refer to the cutting device in a fiber-reinforced composite profile cutting and blanking equipment disclosed in authorization announcement number CN221233132U (see paragraphs

[0043] to

[0054] of the specification and appendix of the specification). Figure 1 and appendix Figure 2 (This will not be elaborated upon here;)

[0036] The positioning component 17 can adopt the structure of a positioning component in a fiber-reinforced composite profile cutting and blanking device disclosed in patent announcement number CN221233132U, or it can adopt the following structure, including a slider 1701, a support frame 1702 fixed on the slider 1701, a first cylinder 1703 fixed on the support frame 1702, a support rod 1704 fixed to the lower part of the power output end of the first cylinder 1703, and a first cylinder 1704 hinged to the output rod of the first cylinder 1703. The components include a connecting rod 1705, a slanted rod portion 1706 hinged to the end of the first connecting rod 1705 away from the first cylinder 1703, a vertical rod portion 1707 integrally formed on the end of the slanted rod portion 1706 away from the first connecting rod 1705, an abutment plate 1708 fixed to the lower end of the vertical rod portion 1707, and a limit switch 1709 mounted on the abutment plate 1708. The connecting section between the slanted rod portion 1706 and the vertical rod portion 1707 is hinged to the end of the support rod 1704 away from the first cylinder 1703.

[0037] like Figure 4 As shown, the unloading conveyor includes a support leg 10, an upper support square steel 12 fixedly connected to the upper end of the support leg 10, and a second slide rail 13 fixedly connected to the upper support square steel 12. A movable square steel 14 is slidably connected to the second slide rail 13. A guide rail 16 fixedly connected to the movable square steel 14 extends to the cutting platform 1, and the guide rail 16 is fixed to the cutting platform 1 by bolts.

[0038] Specifically, the number of support legs 10 is three and they are inverted T-shaped structures. Support legs 11 are provided at both ends of the support legs 10. The upper part of the support legs 11 is a threaded rod, and the threaded rod of the support leg 11 passes through the support leg 10. Bolts are provided on the upper and lower sides of the support leg 10 corresponding to the threaded rod. The height of the material conveying frame can be adjusted by adjusting the bolts on the upper and lower surfaces of the support leg 10. The length of the profile is determined by fixing the distance fixing component 17 in the corresponding position. By setting the guide rail 16, the distance fixing component 17 can be moved to a fixed distance according to the cutting length.

[0039] like Figure 1As shown, a lower support square steel 18 is fixedly connected to the inner side of the support leg 10. There are two lower support square steels 18, which are horizontally fixed between the two support legs 10. A flipping component is provided on the side of the lower support square steel 18. There are two flipping components, which are located between the two support legs 10. By setting the flipping components, the cut profile can be automatically unloaded.

[0040] Specifically, when the moving mechanism of the cutting device moves, it drives the top plate of the cutting device to move. The top plate drives the guide rail 16 fixed on it to move. The guide rail 16 drives the moving square steel 14 to move. The moving square steel 14 drives the L-shaped plate 19 to move. The slider on the L-shaped plate 19 slides along the guide rail on the lower support square steel 18. The slider on the moving square steel 14 moves along the second slide rail 13. The lower support square steel 18 is provided with a guide rail. The L-shaped plate 19 is provided with a slider on the side facing the support square steel 18.

[0041] like Figure 5 and Figure 6 As shown, the flipping assembly includes an L-shaped plate 19 fixed on the lower support square steel 18, a third cylinder 20 with one end hinged to the L-shaped plate 19, and a transmission plate 2 hinged to the other end of the third cylinder 20. The transmission plate 2 is hinged to the support leg 10.

[0042] Specifically, the upper end of the L-shaped plate 19 is welded to the outer side of the movable square steel 14. A hinged base 23 is fixedly connected to the horizontal plate on the L-shaped plate 19. The bottom end of the third cylinder 20 is hinged to the hinged base 23. The extended end of the third cylinder 20 is connected to a connector 21. The other end of the connector 21 is hinged to the fixed plate 22 at the bottom of the transmission plate 2. In the initial state, the extended end of the third cylinder 20 is in an extended state, and the transmission plate 2 is in a horizontal state. When unloading is required, the extended end of the third cylinder 20 is shortened, and the transmission plate 2 gradually tilts until the cut profile falls off.

[0043] like Figure 5 and Figure 6 As shown, a placement rack for placing cut profiles is provided on the upper surface of the lower support square steel 18. The placement rack includes a crossbar 24 fixed to the upper side of the lower support square steel 18 and a baffle 25 fixed to the end of the crossbar 24. The crossbar 24 is perpendicular to the lower support square steel 18, and there are four crossbars 24. Each flipping component is fixedly connected to both sides of the crossbar 24. By setting the crossbar 24, the cut profiles can be placed. In order to prevent too many profiles from falling to the ground, the baffle 25 is fixedly connected to the edge of the crossbar 24.

[0044] It should be noted that, in specific implementation of this utility model, the first cylinder 1703, the second cylinder of the moving structure 7, the limit switch 170, the cutting motor of the lower structure component 3, and the fourth cylinder that drives the cutting motor to lift are electrically connected to the PLC controller of the production line.

[0045] The working process of the fiber-reinforced polyurethane profile cutting and blanking equipment provided by this utility model is as follows:

[0046] In the initial state, the lower cutting assembly 3 is located at the leftmost end of the cutting platform 1, the saw blade 306 in the lower cutting assembly 3 is located on the lower side of the upper panel of the cutting platform 1, the lower pressure plate on the pressing structure 6 is located at the highest position, and the horizontal distance from the saw blade 306 to the contact plate 1708 when it is in the vertical state is measured according to the required cutting length of the profile and fixed.

[0047] After the profile is transferred from the previous station to the cutting and blanking equipment, the end of the profile abuts against the contact plate 1708 and triggers the limit switch 1709. After the PLC controller of the production line receives the signal from the limit switch 1709, the PLC controller simultaneously sends a running command to the clamping structure 6. The clamping structure 6 moves downward, and finally the lower pressure plate cooperates with the cutting platform 1 to clamp and fix the profile. The lower cutting component 3 moves upward, and the saw blade 15 cuts the profile.

[0048] The fixed-distance component 17 flips upward, and the moving structure 7 drives the lower cutting component and the unloading conveyor to move together with the profile. After the second cylinder of the moving structure 7 retracts to its shortest state, the PLC controller controls the second cylinder to extend. At the same time, the operator uses their hand or other tools to fix the cut profile. In this way, after the unloading conveyor returns to its original position, the cut profile is still in the position to be conveyed. That is, at this time, the cut profile falls completely on the transmission plate 2. Then the PLC controller controls the extension end of the third cylinder 20 to shorten, and the transmission plate 2 gradually tilts. The cut profile falls onto the crossbar 24. Then the PLC controller controls the third cylinder 20 to extend again, and the transmission plate 2 returns to the horizontal state. Then the above actions are repeated to complete the cutting and unloading of the next section of profile.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
