Description

Technical Field

[0001] This utility model relates to the field of profile production technology, and in particular to a frame profile cutting device and a frame profile pultrusion production line. Background Technology

[0002] The main production method for frame profiles is pultrusion. The raw materials are combed and then reach the pultrusion mold. Under certain pressure and temperature conditions, they are cured and formed. The formed frame products are continuously pulled out by the power provided by the traction machine, and then cut to a fixed length by the cutting machine according to the measured length signal.

[0003] In a currently disclosed cutting machine, the cutting mechanism mainly uses a downward-pressing cylinder to clamp and limit the frame profile from top to bottom. Insufficient clamping force can cause the frame profile to slip, leading to deviations in the cutting length and problems with the cutting blade getting stuck when it descends after cutting. Furthermore, if the straightness of the frame profile is severely deviated, the contact area between the cylinder and the frame will decrease, making the slippage even more severe, and in some cases, the frame may not be clamped at all.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution: In some embodiments of this application, a frame profile cutting device is provided, comprising: A cutting table, wherein a first limiting part is provided on the cutting table; A side-pressing portion is configured to move the frame line from the side of the frame profile toward the first limiting portion, so that the frame profile abuts against the first limiting portion; A pressing portion, configured to press the frame profile downward toward the cutting table; A cutting section is disposed below the cutting table, the cutting section includes a cutting blade, and the cutting table is provided with an opening for the cutting blade to be exposed; A lifting motion unit, wherein the cutting part is disposed on the lifting motion unit, and the lifting motion unit is configured to drive the cutting part to move up and down; A lateral movement unit, wherein the lifting movement unit is disposed on the lateral movement unit, and the lateral movement unit is configured to drive the cutting table to move along the length direction of the frame profile.

[0007] In some embodiments of this application, two first limiting parts are provided on the cutting table, and the two first limiting parts are arranged at intervals along the conveying direction of the frame profile. Two side pressing parts are provided, and the two first limiting parts and the two side pressing parts are arranged in a one-to-one correspondence.

[0008] In some embodiments of this application, the side pressure portion includes a side pressure drive member and a side pressure plate, wherein the side pressure drive member drives the side pressure plate to move toward or away from the first limiting portion.

[0009] In some embodiments of this application, the first limiting portion includes a first limiting plate, which extends along the length direction of the frame profile. The side pressure plate is disposed opposite to the first limiting plate, and the side pressure plate pushes the frame profile toward the first limiting plate.

[0010] In some embodiments of this application, the first limiting portion further includes a first inclined plate, which extends inclinedly toward the frame profile along the conveying direction of the frame profile. The cutting table is provided with a second limiting part, which includes a second inclined plate. Along the conveying direction of the frame profile, the second inclined plate extends inclinedly toward the frame profile, and the first inclined plate and the second inclined plate are arranged opposite to each other.

[0011] In some embodiments of this application, the pressing part includes a pressing drive and a pressing plate, and the pressing drive drives the pressing plate to move toward or away from the cutting table.

[0012] In some embodiments of this application, a protective cover is provided on the cutting table, the protective cover is directly opposite the opening, and the pressing part is provided on the protective cover.

[0013] In some embodiments of this application, the lateral movement part includes a lateral drive member and a lateral movement member. The lateral drive member drives the lateral movement member to move along the length direction of the frame profile. A guide post is provided between the lateral movement member and the cutting table. The lifting motion unit includes a lifting drive and a lifting motion component. The lifting motion component is slidably connected to the guide column. The lifting drive drives the lifting motion component to move up and down. The cutting part is disposed on the lifting motion component.

[0014] In some embodiments of this application, the bottom of the lifting drive component is rotatably connected to the lateral moving component, and the power output end of the lifting drive component is connected to the lifting moving component through a flange floating joint.

[0015] In some embodiments of this application, a frame profile pultrusion production line is also provided, including the frame profile cutting device described above.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are: The cutting device disclosed in this application uses a dual clamping design of lateral and downward pressure to stably limit the frame profile during the cutting process, completely eliminating slippage and laying the foundation for subsequent precision control of cutting length and smooth movement of the cutting blade.

[0017] During the cutting process, the double clamping action of the side pressure part and the downward pressure part covers the front and rear ends of the frame profile cutting point. Both the uncut profile segment and the cut profile segment are pressed by the side pressure and downward pressure points. This structure can ensure that the frame profiles at both ends remain in a fixed position after cutting and will not shift or warp due to loss of constraint, thus avoiding contact between the cutting blade and the frame profile when it descends.

[0018] After cutting is completed, when the lifting motion unit drives the cutting unit to descend, the cutting blade can smoothly fall back to the bottom of the cutting table from the opening because the positions of the frame profiles at both ends are stable and do not interfere with the cutting blade. This completely eliminates jamming, extends the service life of the cutting blade, reduces the risk of equipment failure caused by jamming, and improves the safety and continuity of cutting operations.

[0029] In some embodiments of this application, a frame profile pultrusion production line is provided. Raw materials are combed and fed to a pultrusion die, where they are cured and molded under specific pressure and temperature conditions. Power provided by a traction machine continuously pulls out the molded frame products, which are then cut to a fixed length by a cutting device based on measured length signals. The frame profile 10 can be a photovoltaic frame, bracket, door and window profile, etc.

[0030] In some embodiments of this application, a frame profile cutting device is provided. Figure 1 This is a structural diagram of a cutting device. Figure 2 This is a side view of the cutting device. Figure 3 This is a top view of the cutting device.

[0031] The cutting device includes a cutting table 410, on which the frame profile 10 to be cut is conveyed. A first limiting part 471 is provided on the cutting table 410. Two first limiting parts 471 are provided at intervals along the length direction of the frame profile 10.

[0032] The cutting device also includes a side pressing part 420. Two side pressing parts 420 are provided at intervals on the cutting table 410 along the length direction of the frame profile 10. The side pressing parts 420 and the first limiting part 471 are arranged opposite each other in the horizontal direction.

[0033] The side-pressing portion 420 is configured to move the frame wire from the side of the frame profile 10 toward the first limiting portion 471, causing the frame profile 10 to abut against the first limiting portion 471. One side of the frame profile 10 abuts against the first limiting portion 471, and the other opposite side abuts against the side-pressing portion 420, clamping and limiting the frame profile 10 between the first limiting portion 471 and the side-pressing portion 420. The cooperation of the first limiting portion 471 and the side-pressing portion 420 restricts the horizontal movement of the frame profile 10.

[0034] The cutting device also includes a pressing part 430, which is configured to press the frame profile 10 downwards toward the cutting table 410. The pressing part 430 is located between two first limiting parts 471. The bottom of the frame profile 10 abuts against the cutting table 410, and the top abuts against the pressing part 430, clamping and limiting the frame profile 10 between the cutting table 410 and the pressing part 430. The vertical movement of the frame profile 10 is restricted by the cooperation between the pressing part 430 and the cutting table 410.

[0035] The pressing part 430 has a plurality of parts, for example two, and the plurality of pressing parts 430 are spaced apart along the length direction of the frame profile 10.

[0036] The cutting device also includes a cutting section 440, which is disposed below the cutting table 410. The cutting section 440 includes a cutting blade 441 and a cutting drive motor 442, which drives the cutting blade 441 to rotate. The cutting table 410 has an opening (not shown) for the cutting blade 441 to be exposed. The frame profile 10 is located above the opening, and the cutting blade 441 is exposed from the opening to cut the frame profile 10.

[0037] A first protective cover 411 is provided on the outer side of the cutting disc 441. Figure 2 The first protective shield 411 is omitted.

[0038] Taking two pressing parts 430 as an example, the opening is located between the two pressing parts 430.

[0039] The cutting device also includes a lifting motion unit 450, and a cutting unit 440 is mounted on the lifting motion unit 450. Specifically, a cutting drive motor 442 is mounted on the lifting motion unit 450. The lifting motion unit 450 is configured to drive the cutting unit 440 to move up and down. When cutting is required, the lifting motion unit 450 drives the cutting unit 440 to rise, and the cutting blade 441 protrudes from the opening to cut the frame profile 10. When cutting is not required, the lifting motion unit 450 drives the cutting unit 440 to descend, and the cutting blade 441 disengages from the frame profile 10.

[0040] The cutting device also includes a lateral movement unit 460, and a lifting movement unit 450 is disposed on the lateral movement unit 460. The lateral movement unit 460 is configured to drive the cutting table 410 to move along the length direction of the frame profile 10.

[0041] The operation process of the cutting device is as follows: When no cutting is being performed, the cylinder of the transverse motion unit 460 extends, driving the cutting table 410 to move toward the direction of the pultrusion die. The frame is provided with a limiting structure for the transverse motion unit 460. After the transverse motion unit 460 contacts the limiting structure, the cutting device reaches the initial position. The frame profile 10 continues to extend backward under the action of the front-end traction machine. After the frame profile 10 reaches the specified length, the cutting device starts to operate. The side pressing part 420 moves toward the first limiting part 471 to clamp and limit the frame profile 10 between the first limiting part 471 and the side pressing part 420, thereby achieving positioning of the frame profile 10 in the width direction. The cylinder of the lateral movement part 460 retracts, putting the entire cutting device in a free state. Due to the friction between the first limiting part 471 and the side pressing part 420 clamping the frame profile 10, the entire cutting device moves to the rear end under the action of the front traction machine, ensuring that the relative position between the cutting device and the frame profile 10 remains unchanged. The pressing part 430 presses down on the frame profile 10, further increasing the clamping force on the frame profile 10. The dual action of side pressing and downward pressing makes the frame profile 10 in close contact with the cutting mechanism, ensuring the clamping effect on the frame profile 10. The lifting motion unit 450 is started, driving the cutting unit 440 to rise, the cutting drive motor 442 is started, and the cutting blade 441 extends out of the opening to cut the frame profile 10; After cutting is completed, the lifting motion unit 450 drives the cutting unit 440 to descend, the cutting blade 441 descends, and the cutting drive motor 442 stops working.

[0042] By employing a dual action of side pressure and downward pressure, after cutting, both the front and rear end frame profiles 10 (one frame profile is uncut, and the other is cut) are subjected to side pressure and downward pressure. Compared with the traditional single-point pressure, the two-point pressure provides a better clamping effect for the frame profiles 10, ensuring that the front and rear end frame profiles 10 do not slip and that the end frame profiles 10 do not contact the cutting blade 441 when it descends. This solves the problem of the cutting blade 441 getting stuck when it descends.

[0043] After the cutting blade 441 descends to the bottom, the side pressing part 420 and the downward pressing part 430 reset, releasing the clamping of the frame profile 10. The cylinder of the lateral movement part 460 extends again, and the entire cutting device returns to the initial position under the action of the lateral movement part 460.

[0044] The cutting device disclosed in this application has two side-pressing portions 420 spaced apart along the length of the frame profile 10, forming a horizontal opposing clamping with the first limiting portion 471 on the cutting table 410. The side-pressing portions 420 apply force from the side of the profile, causing one side of the profile to abut against the first limiting portion 471 and the other side to abut against the side-pressing portions 420, completely restricting the profile's deviation in the width direction. Even if the straightness deviation of the frame profile 10 is severe, the two spaced-apart side-pressing portions 420 can still ensure sufficient clamping contact area through multi-point contact, avoiding the problem of insufficient pressure on the frame or reduced contact area leading to increased slippage in traditional structures.

[0045] The cutting device disclosed in this application employs multiple (e.g., two) pressing portions 430 spaced apart along the length of the frame profile 10, with the pressing portions 430 located between two first limiting portions 471. This structure ensures that the bottom of the profile is tightly pressed against the cutting table 410 and the top is stably pressed by the pressing portions 430, resulting in a more uniform distribution of clamping force. This, combined with the lateral pressure in the horizontal direction, significantly enhances the overall clamping force.

[0046] The cutting device disclosed in this application uses a dual clamping design of lateral and downward pressure to stably limit the frame profile 10 during the cutting process, completely eliminating slippage and laying the foundation for subsequent precision control of cutting length and smooth movement of the cutting blade 441.

[0047] The cutting device disclosed in this application, after the frame profile 10 reaches the specified length, first performs horizontal clamping by the side pressure part 420, achieving precise positioning in the width direction of the profile and avoiding deviation in the length measurement reference caused by horizontal offset of the profile. After the side pressure part 420 clamps, the cylinder of the transverse movement part 460 retracts, putting the cutting device in a free state. Due to the clamping friction between the side pressure part 420 and the first limiting part 471 on the frame profile 10, the cutting device can move synchronously to the rear end with the frame profile 10 under the drive of the front traction machine. During this process, there is no relative sliding between the cutting device and the frame profile 10, and the cutting position of the cutting part 440 always remains consistent with the preset specified length position, realizing follow-up cutting.

[0048] During the cutting process, the double clamping action of the side pressure part 420 and the downward pressure part 430 covers both ends of the cut edge of the frame profile 10. Both the uncut profile segment and the cut profile segment are clamped by the side pressure and downward pressure points. Compared with the traditional single-point clamping, this structure can ensure that the frame profiles 10 at both ends remain in a fixed position after cutting, and will not shift or warp due to loss of constraint, thus preventing the cutting blade 441 from contacting the frame profile 10 when it descends.

[0049] After cutting is completed, when the lifting motion unit 450 drives the cutting unit 440 to descend, since the positions of the two end frame profiles 10 are stable and do not interfere with the cutting blade 441, the cutting blade 441 can smoothly fall back from the opening to below the cutting table 410, completely eliminating jamming, extending the service life of the cutting blade 441, reducing the risk of equipment failure caused by jamming, and improving the safety and continuity of cutting operations.

[0050] In some embodiments of this application, the cutting table 410 is provided with two first limiting parts 471, which are arranged at intervals along the conveying direction of the frame profile 10. Two side pressing parts 420 are provided, with each of the two first limiting parts 471 corresponding to one of the two side pressing parts 420. Two pressing parts 430 are located between the two first limiting parts, with their openings located between the two pressing parts 430.

[0051] In some embodiments of this application, the side pressure part 420 includes a side pressure drive member 421 and a side pressure plate 422. The side pressure drive member 421 drives the side pressure plate 422 to move toward or away from the first limiting part 471. For example, the side pressure drive member 421 is a cylinder. The side pressure drive member 421 is fixedly mounted on the cutting table 410.

[0052] In some embodiments of this application, the first limiting part 471 includes a first limiting plate 4711, which extends along the length direction of the frame profile 10. A side pressure plate 422 is disposed opposite to the first limiting plate 4711, and the side pressure plate 422 pushes the frame profile 10 toward the first limiting plate 4711.

[0053] The first limiting part 471 also includes a mounting plate 4713, which is fixed to the cutting table 410 by bolts or other connecting parts. The first limiting plate 4711 is fixed to the mounting plate 4713 and is a vertical plate.

[0054] The mounting plate 4713 is provided with an elongated hole 4714 through which bolts pass. The extension direction of the elongated hole 4714 is perpendicular to the frame profile 10, and the position of the first limiting part 471 can be adjusted through the elongated hole 4714.

[0055] In some embodiments of this application, a mounting block 4731 is fixedly provided on the cutting table 410, a screw 4733 is passed through the mounting block 4731, and a limiting block 4732 is provided at the end of the screw 4733. The limiting block 4732 abuts against the mounting plate 4713, and the mounting plate 4713 is limited by the screw 4733 to ensure that the first limiting part 471 will not move under the pressing action of the side pressing part 420.

[0056] In some embodiments of this application, the first limiting part 471 further includes a first inclined plate 4712, which extends inclinedly toward the side profile 10 along the conveying direction of the side profile 10.

[0057] A second limiting part 472 is provided on the cutting table 410. The second limiting part 472 is disposed opposite to the first limiting part 471, and a gap is formed between them for the frame profile 10 to pass through. The second limiting part 472 and the side pressing part 420 are located on the same side of the frame profile 10, and along the conveying direction of the frame profile 10, the side pressing part 420 is located downstream of the second limiting part 472.

[0058] The second limiting part 472 includes a second inclined plate 4721. Along the conveying direction of the frame profile 10, the second inclined plate 4721 extends inclinedly towards the frame profile 10. The first inclined plate 4712 is disposed opposite to the second inclined plate 4721. In other words, the first inclined plate 4712 and the second inclined plate 4721 form a funnel-shaped gap structure, which guides the frame profile 10 and prevents the frame profile 10 from contacting the side pressure part 420 during conveying.

[0059] In some embodiments of this application, the pressing part 430 includes a pressing drive 431 and a pressing plate 432, wherein the pressing drive 431 drives the pressing plate 432 to move toward or away from the cutting table 410. For example, the pressing drive 431 is a cylinder.
