Description

Technical Field

[0001] This utility model relates to the field of resin profile processing technology, specifically to a resin profile cutting and blanking device. Background Technology

[0002] With the rapid development of industries such as construction, furniture, and electronics, resin profiles are increasingly widely used in the manufacturing of various products and engineering construction due to their advantages such as lightweight, corrosion resistance, and good insulation.

[0003] In the current resin profile cutting process, existing cutting devices often have insufficient clamping stability when fixing the profiles. Some devices fix the profiles only through a single or a few contact points, which is difficult to adapt to resin profiles with different cross-sectional shapes and diameters. This causes the profiles to easily shift or vibrate during the cutting process. This unstable clamping state not only causes deviations in the profile cutting dimensions, but also produces obvious burrs on the cut surface, and may even cause local cracking due to uneven stress on the profiles, seriously affecting the processing quality of resin profiles. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a resin profile cutting and blanking device, which has the advantages of stable clamping of resin profiles to reduce displacement vibration during cutting, and can also assist in cooling and chip removal. This solves the problems of unstable clamping in existing cutting devices, which leads to dimensional deviations in profile cutting and burr cracks on the cut surface.

[0005] To achieve the above objectives, this utility model employs the following technical solution: a resin profile cutting and blanking device, comprising a support frame, a feeding mechanism being provided at the top of the support frame near one end, an L-shaped mounting rod being fixedly installed on the side of the support frame near the other end, a hydraulic rod being fixedly installed at the other end of the L-shaped mounting rod, the hydraulic rod being disposed at the top of the support frame, an mounting block being fixedly installed at the output end of the hydraulic rod, a first motor being fixedly installed on the side of the mounting block near the feeding mechanism, the output end of the first motor passing through the mounting block, a saw blade being fixedly installed at the output end of the first motor, two clamping assemblies for clamping both ends of the resin profile being symmetrically arranged at the top of the support frame near the hydraulic rod, the two clamping assemblies being respectively disposed on both sides of the saw blade, a control unit being provided on the side of the mounting block away from the L-shaped mounting rod, the control unit connecting the two clamping assemblies together, the clamping assembly being composed of an annular block and a top rod.

[0006] As a preferred technical solution of this utility model, the clamping assembly includes a base, which is fixedly installed on the top of the support frame near the L-shaped mounting rod. An annular block is fixedly installed on the top of the base, and a mounting hole is provided on one side of the annular block. An movable hole is provided on the inner side of the mounting hole.

[0007] As a preferred embodiment of this utility model, the clamping assembly further includes a movable ring, which is rotatably installed inside the mounting hole. An arc-shaped guide hole is provided on one side of the movable ring, and a connecting rod is fixedly installed on the outer side of the movable ring. The connecting rod passes through the movable hole and is used in conjunction with the control unit.

[0008] As a preferred technical solution of this utility model, the clamping assembly further includes an annular cover plate, which is fixedly installed on the side of the annular block near the mounting hole. The annular cover plate is provided with a plurality of sliding grooves at equal intervals on the circumference of the side away from the annular block, and a sliding hole is provided on one side of the inner side of the sliding groove.

[0009] As a preferred technical solution of this utility model, the clamping assembly further includes several push rods, which are movably installed inside the slide groove. A guide rod is fixedly installed on the side of the push rod near the slide hole. The guide rod is movably installed inside the slide hole. The other end of the guide rod is movably sleeved inside the arc-shaped guide hole. An arc-shaped clamping plate is fixedly installed on the end of the push rod near the center of the annular cover plate.

[0010] As a preferred embodiment of this utility model, the control unit includes a rectangular rod, which is fixedly installed on the side of the mounting block away from the L-shaped mounting rod. L-shaped rods are fixedly installed on both sides of the rectangular rod. A rectangular groove is provided on the side of the L-shaped rod away from the rectangular rod, and limit grooves are symmetrically provided on both sides of the interior of the rectangular groove.

[0011] As a preferred technical solution of this utility model, the control unit further includes a slider, which is movably installed inside the rectangular groove. Limiting blocks are symmetrically fixedly installed on both sides of the slider, and the limiting blocks are movably sleeved inside the limiting groove. A spring is fixedly installed on the top of the slider, and the other end of the spring is fixedly installed to the inner top surface of the rectangular groove. One side of the slider is rotatably installed to one side of the connecting rod.

[0012] As a preferred technical solution of this utility model, a base two is fixedly installed on the top of the support frame near the saw blade end, and an annular hollow tube is fixedly installed on the top of the base two. Several nozzles are fixedly installed at equal intervals around the annular hollow tube on the side near the saw blade, and an air inlet pipe is fixedly installed on the outer side of the annular hollow tube near the L-shaped mounting rod.

[0013] The beneficial effects of this utility model are as follows: This invention uses a support frame as a base, a feeding mechanism to transport profiles to the cutting position, and a hydraulic rod on an L-shaped mounting rod to drive the mounting block, which in turn drives the first motor and saw blade to move and complete the cutting. The clamping components on both sides of the saw blade, relying on the annular block, movable ring, top rod and arc-shaped clamping plate, can clamp the profiles from the circumferential direction. At the same time, the control unit linked to the mounting block can drive the clamping components to tighten before cutting, so as to avoid profile displacement and uniformly clamp the profiles to reduce profile vibration, thus solving the problems of unstable clamping and easy burr cracking in traditional devices.

[0014] The annular hollow tube on the support frame is connected to an external air pump through an outer air inlet pipe. The air pump can deliver high-pressure airflow into the annular hollow tube, and then spray it evenly onto the cutting contact surface between the saw blade and the profile through circumferentially distributed nozzles. The high-pressure airflow can not only remove the heat generated by cutting in real time, preventing the resin from melting and sticking to the saw blade due to high temperature and producing burrs, but also blow away cutting debris in time to prevent debris accumulation from affecting cutting accuracy. Combined with the stable clamping structure, it effectively reduces burrs and cracking problems when cutting resin profiles, taking into account both material feeding stability and processing quality.

[0017] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0018] Figures 1-12 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 12 The present invention will be further described below.

[0019] A resin profile cutting and blanking device includes a support frame 1. A feeding mechanism 2 is provided on the top of the support frame 1 near one end. An L-shaped mounting rod 3 is fixedly installed on the side of the support frame 1 near the other end. A hydraulic rod 4 is fixedly installed on the other end of the L-shaped mounting rod 3. The hydraulic rod 4 is located on the top of the support frame 1. A mounting block 5 is fixedly installed on the output end of the hydraulic rod 4. A first motor 6 is fixedly installed on the side of the mounting block 5 near the feeding mechanism 2. The output end of the first motor 6 passes through the mounting block 5. A saw blade 7 is fixedly installed on the output end of the first motor 6. Two clamping assemblies for clamping both ends of the resin profile are symmetrically arranged on the top of the support frame 1 near the top of the hydraulic rod 4. The two clamping assemblies are respectively located on both sides of the saw blade 7. A control unit is provided on the side of the mounting block 5 away from the L-shaped mounting rod 3. The control unit connects the two clamping assemblies together. The clamping assembly consists of an annular block 14 and a top rod 23.

[0020] In this embodiment, a support frame 1 provides a stable mounting position for the feeding mechanism 2, the L-shaped mounting rod 3, and the clamping assembly. A rectangular mounting slot is provided on the top of the support frame 1 to provide space for the installation of the screw in the feeding mechanism 2, ensuring stable assembly and orderly conveying of the resin profile. The feeding mechanism 2 includes a rectangular mounting slot, a second motor, a screw, a rectangular block, a fixing block, a discharge hole, a threaded hole, a threaded rod, an extrusion plate, and a handwheel. The rectangular mounting slot is located on the top of the support frame 1, providing space for the screw to move and restricting its rotation trajectory. In use, the resin profile is first passed through the discharge hole on one side of the fixing block. Then, the handwheel is turned to move the threaded rod downwards along the threaded hole. The extrusion plate at the bottom of the threaded rod moves downwards accordingly, engaging with the inner wall of the discharge hole to clamp and fix the profile. Subsequently, the second motor starts, driving the screw to rotate within the rectangular mounting slot. The rectangular block, threaded to the outside of the screw, moves the top fixing block and the fixed profile towards the saw blade 7, achieving automatic feeding of the profile. The L-shaped mounting rod... 3. One end is fixed to the side of the support frame 1 near the other end, and the other end is fixedly installed with a hydraulic rod 4. The hydraulic rod 4 is mounted on the top of the support frame 1 through its own L-shaped structure, so that the output end of the hydraulic rod 4 can be accurately aligned with the cutting area. The output end of the hydraulic rod 4 is fixed to the mounting block 5, which can provide driving force for the up and down movement of the mounting block 5, the first motor 6 and the saw blade 7. The mounting block 5 provides a stable mounting platform for the first motor 6, avoiding the shaking of the motor during operation and affecting the rotational stability of the saw blade 7. The first motor 6 provides power for the high-speed rotation of the saw blade 7. By stabilizing the output speed, it ensures that the rotation speed of the saw blade 7 is uniform, ensuring cutting efficiency and the flatness of the cutting surface. The clamping assembly consists of an annular block 14 and a top rod 23, which are symmetrically arranged on both sides of the saw blade 7 and fixed to the top of the support frame 1 near the hydraulic rod 4. It is used to clamp the two ends of the resin profile before cutting. The control unit is located on the side of the mounting block 5 away from the L-shaped mounting rod 3 and connects the two clamping assemblies together. It can drive the clamping assembly to move synchronously with the up and down movement of the mounting block 5.

[0021] Specifically, the clamping assembly includes a base 13, which is fixedly installed on the top of the support frame 1 near the L-shaped mounting rod 3. An annular block 14 is fixedly installed on the top of the base 13. A mounting hole 15 is provided on one side of the annular block 14, and a movable hole 16 is provided on the inner side of the mounting hole 15.

[0022] In this embodiment, by fixing the base 13 to the top of the support frame 1 near the L-shaped mounting rod 3, the clamping assembly can be stably assembled on the support frame 1, ensuring the positional correspondence between the clamping assembly and the saw blade 7, and ensuring that the cutting ends of the resin profile can be accurately clamped subsequently. The annular block 14 is fixed to the top of the base 13, and the mounting hole 15 on one side provides rotational mounting space for the movable ring 17, which can limit the range of motion of the movable ring 17 and ensure that the movable ring 17 can only rotate stably within the mounting hole 15. At the same time, the movable hole 16 on one side inside the mounting hole 15 can be used for the connecting rod 19 to pass through, providing an active channel for the connecting rod 19, so that the connecting rod 19 can drive the movable ring 17 to move synchronously.

[0023] Specifically, the clamping assembly also includes a movable ring 17, which is rotatably installed inside the mounting hole 15. An arc-shaped guide hole 18 is provided on one side of the movable ring 17, and a connecting rod 19 is fixedly installed on the outer side of the movable ring 17. The connecting rod 19 passes through the movable hole 16 and is used in conjunction with the control unit.

[0024] In this embodiment, the movable ring 17 is rotatably installed inside the mounting hole 15. The arc-shaped guide hole 18 on one side of the movable ring 17 can cooperate with the guide rod 24. When the movable ring 17 rotates, it can drive the guide rod 24 to move through the arc-shaped guide hole 18, thereby driving the top rod 23 to move closer to the profile to achieve clamping. When the L-shaped rod 9 in the control unit moves downward with the mounting block 5, it can push the connecting rod 19 downward to drive the movable ring 17 to rotate stably in the mounting hole 15.

[0025] Specifically, the clamping assembly also includes an annular cover plate 20, which is fixedly installed on the side of the annular block 14 near the mounting hole 15. The annular cover plate 20 has several grooves 21 equidistantly spaced on the circumference of the side away from the annular block 14, and a sliding hole 22 is provided on one side of the inner side of the groove 21.

[0026] In this embodiment, by fixing the annular cover plate 20 to the side of the annular block 14 near the mounting hole 15, its primary function is to shield and protect the movable ring 17 inside the mounting hole 15, preventing debris generated during resin profile cutting from entering the mounting hole 15 and preventing debris from jamming the movable ring 17 and affecting its rotational flexibility. Simultaneously, several equidistant sliding grooves 21 are provided on the circumference of the side away from the annular block 14, providing a stable installation and movement space for the push rod 23. This restricts the movement direction of the push rod 23, ensuring that it can only move radially along the sliding grooves 21. This, in turn, ensures that the push rod 23 drives the arc-shaped clamping plate 25 to clamp the profile precisely without deviation. The sliding hole 22 slides... Hole 22 is opened inside one side of the slide groove 21 and communicates with the mounting hole 15 on the other side of the annular cover plate 20. It is mainly used for the guide rod 24 to pass through, providing a movable channel for the guide rod 24. One end of the guide rod 24 can be movably fitted into the arc-shaped guide hole 18 of the movable ring 17, and the other end can be fixedly connected to the top rod 23 in the slide groove 21. Thus, the guide rod 24, driven by the arc-shaped guide hole 18, drives the top rod 23 to move along the slide groove 21 along the slide hole 22. The slide hole 22 can limit the range of motion of the guide rod 24, prevent the guide rod 24 from deviating during power transmission, and ensure that the guide rod 24 can stably convert the rotational motion of the movable ring 17 into the radial movement of the top rod 23.

[0027] Specifically, the clamping assembly also includes several push rods 23, which are movably installed inside the slide groove 21. A guide rod 24 is fixedly installed on the side of the push rod 23 near the slide hole 22. The guide rod 24 is movably installed inside the slide hole 22. The other end of the guide rod 24 is movably sleeved inside the arc-shaped guide hole 18. An arc-shaped clamping plate 25 is fixedly installed on the end of the push rod 23 near the center of the annular cover plate 20.

[0028] In this embodiment, the push rod 23 is movably installed inside the slide groove 21, and a guide rod 24 is fixed on the side of the push rod 23 near the slide hole 22. The guide rod 24 can receive the driving force from the arc-shaped guide hole 18. When the guide rod 24 moves along the slide hole 22, the push rod 23 can move radially and stably along the slide groove 21. At the same time, an arc-shaped clamping plate 25 is fixed at the end of the push rod 23 near the center of the annular cover plate 20, which can drive the arc-shaped clamping plate 25 to move closer to or away from the profile. When multiple sets of push rods 23 converge towards the center along the slide groove 21, the profile can be clamped together by the arc-shaped clamping plate 25. Since the movement trajectory of the push rod 23 along the slide groove 21 is fixed, it can ensure that the position of the arc-shaped clamping plate 25 is accurate when it contacts the profile, avoid profile deviation, and ensure clamping stability.

[0029] Specifically, the control unit includes a rectangular rod 8, which is fixedly installed on the side of the mounting block 5 away from the L-shaped mounting rod 3. L-shaped rods 9 are fixedly installed on both sides of the rectangular rod 8. A rectangular groove 10 is opened on the side of the L-shaped rod 9 away from the rectangular rod 8. Limiting grooves are symmetrically opened on both sides inside the rectangular groove 10.

[0030] In this embodiment, by fixing the rectangular rod 8 to the side of the mounting block 5 away from the L-shaped mounting rod 3, and fixing the L-shaped rods 9 on both sides, the movement of the mounting block 5 can be synchronously transmitted to the L-shaped rods 9 on both sides. At the same time, the structure itself provides stable support for the L-shaped rods 9, ensuring that the L-shaped rods 9 will not wobble or deviate when moving up and down with the mounting block 5. The rectangular groove 10 is opened on the side of the L-shaped rod 9 away from the rectangular rod 8, and the limiting grooves are symmetrically opened on both sides inside. It is mainly used to install the slider 12, provide the slider 12 with the trajectory for up and down movement, limit the range of motion of the slider 12, and ensure that the slider 12 can only move in a straight line along the rectangular groove 10. The limiting grooves are symmetrically opened on both sides inside the rectangular groove 10, and are used to cooperate with the limiting blocks on both sides of the slider 12 to limit the movement trajectory of the slider 12 in the rectangular groove 10, and prevent the slider 12 from deviating to the left or right or falling off during the up and down movement.

[0031] Specifically, the control unit also includes a slider 12, which is movably installed inside the rectangular groove 10. Limiting blocks are symmetrically fixedly installed on both sides of the slider 12, and the limiting blocks are movably fitted inside the limiting groove. A spring 11 is fixedly installed on the top of the slider 12, and the other end of the spring 11 is fixedly installed to the inner top surface of the rectangular groove 10. One side of the slider 12 is rotatably installed to one side of the connecting rod 19.

[0032] In this embodiment, the slider 12 is movably installed inside the rectangular groove 10, with one side rotatably mounted to the connecting rod 19 of the clamping assembly. When the mounting block 5 moves downward under the action of the hydraulic rod 4, the L-shaped rod 9 moves downward accordingly, causing the slider 12 to move downward synchronously. The slider 12 drives the movable ring 17 to rotate through the connecting rod 19, thereby driving the top rod 23 of the clamping assembly to clamp the profile with the arc-shaped clamping plate 25. After the profile is clamped and fixed, the connecting rod 19 can no longer move, and the slider 12 and the connecting rod 19 remain in fixed positions. At this time, the L-shaped rod 9 continues to move downward with the mounting block 5, and the slider 12 remains stationary relative to the L-shaped rod 9, providing conditions for the compression of the spring 11. After cutting is completed, the L-shaped rod 9 moves upward. After the spring 11 returns to its initial state, the L-shaped rod 9 drives the slider 12 to move upward. The slider 12 drives the movable ring 17 to rotate in the opposite direction through the connecting rod 19, realizing the release of the clamping assembly. In addition to fixing the profile, the entire clamping and cutting action is connected to ensure that the two work together. One end of the spring 11 is fixed to the top of the slider 12 and the other end is fixed to the top surface inside the rectangular groove 10. When the mounting block 5 drives the L-shaped rod 9 to move down, the slider 12 first drives the connecting rod 19 to complete the clamping. After the connecting rod 19 can no longer move, the L-shaped rod 9 continues to move down, and the spring 11 is compressed, providing stroke space for the L-shaped rod 9 to drive the first motor 6 and the saw blade 7 to move down for cutting. This ensures that the saw blade 7 can still move down normally to complete the cutting after clamping and fixing. When the L-shaped rod 9 moves up after cutting, the spring 11 gradually returns to its initial state. At this time, the slider 12 does not move. After the spring 11 has fully recovered, the L-shaped rod 9 can continue to move up to drive the slider 12 to move up. The elastic deformation of the spring 11 realizes the connection between the cutting stroke and the clamping stroke, avoiding interference between the two movements.

[0033] Specifically, a base 2 is fixedly installed on the top of the support frame 1 near the saw blade 7. An annular hollow tube is fixedly installed on the top of the base 2. Several nozzles are fixedly installed at equal intervals around the annular hollow tube on one side near the saw blade 7. An air inlet pipe is fixedly installed on the outer side of the annular hollow tube near the L-shaped mounting rod 3.

[0034] In this embodiment, the base 2 is fixedly installed on the top of the support frame 1 near the saw blade 7, serving as the basic mounting carrier for the annular hollow tube. Through its stable connection with the support frame 1, the annular hollow tube is stably supported at a designated position around the saw blade 7, ensuring that the annular hollow tube and nozzles will not shift due to vibration or airflow impact during the cutting operation. The annular hollow tube has a hollow internal structure, which can serve as an airflow delivery channel, evenly distributing the high-pressure airflow from the air inlet pipe to several nozzles installed at equal intervals around the circumference. At the same time, the annular structure allows the nozzles to be evenly distributed around the saw blade 7, ensuring that the airflow can act on the cutting area from multiple directions, avoiding dead zones in cooling or chip removal, improving the cooling and chip removal effect on the saw blade 7 and the cutting surface, and ensuring cutting quality. An air pump is connected to the air inlet pipe to introduce high-pressure airflow into the annular hollow tube, providing a continuous and stable airflow source for the nozzles.

[0035] In summary: When using this utility model, the resin profile to be cut is manually passed through the discharge hole on one side of the fixed block in the feeding mechanism 2. One end of the resin profile is placed inside the discharge hole. The handwheel is manually turned, which drives the threaded rod to move down along the threaded hole at the top of the fixed block. The extrusion plate at the bottom of the threaded rod moves down accordingly, cooperating with the inner wall of the discharge hole to clamp and fix the resin profile. Then, the first motor 6 and the second motor are both connected to external power. The second motor is started, and the output end of the second motor drives the screw to rotate in the rectangular mounting groove at the top of the support frame 1. The rectangular block threaded to the outside of the screw drives the top fixed block and the fixed resin profile to move towards the saw blade 7, realizing automatic feeding of the resin profile until the profile to be cut is moved below the saw blade 7 and located between the two... Between the clamping components, the hydraulic rod 4 is activated. The output end of the hydraulic rod 4 pushes the mounting block 5 downward. The mounting block 5 drives the first motor 6 and the saw blade 7 to move downward synchronously. On the other hand, it drives the rectangular rod 8 and the L-shaped rods 9 on both sides of the control unit to move downward synchronously. When the L-shaped rods 9 move downward, they push the slider 12 in the rectangular groove 10 downward. The slider 12 drives the movable ring 17 to rotate in the mounting hole 15 of the annular block 14 through the connecting rod 19 rotatably connected on one side. When the movable ring 17 rotates, the arc-shaped guide hole 18 on one side drives the guide rod 24 to move along the sliding hole 22 of the annular cover plate 20. The guide rod 24 drives the top rod 23 to converge towards the center along the sliding groove 21 of the annular cover plate 20. The arc-shaped clamping plate 25 at the end of the top rod 23 simultaneously approaches and clamps the resin profile. After the profile is fully clamped at both ends, the connecting rod 19 can no longer move, the slider 12 and the connecting rod 19 remain fixed in position, the L-shaped rod 9 continues to move down with the mounting block 5, the slider 12 remains stationary relative to the L-shaped rod 9, the spring 11 in the rectangular groove 10 is compressed, and the first motor 6 is started at the same time. The output end of the first motor 6 drives the saw blade 7 to rotate at high speed. As the mounting block 5 continues to move down, the high-speed rotating saw blade 7 contacts the resin profile and cuts it. During the cutting process, an air pump is connected to the air inlet pipe. The high-pressure airflow generated by the air pump enters the annular hollow tube through the air inlet pipe, and then is evenly sprayed onto the cutting contact surface between the saw blade 7 and the profile through several nozzles on the side of the annular hollow tube near the saw blade 7, which removes the cutting heat and blows away the debris in real time. After the cutting is completed, the first motor 6 is turned off and the control is activated. Hydraulic rod 4 drives mounting block 5 to move upward, and L-shaped rod 9 moves upward accordingly. Spring 11 in rectangular groove 10 gradually returns to its initial state. During this process, slider 12 does not move. After spring 11 has fully returned to its initial state, L-shaped rod 9 continues to move upward, driving slider 12 to move upward. Slider 12 drives movable ring 17 to rotate in the opposite direction through connecting rod 19. Movable ring 17 drives top rod 23 and arc-shaped clamping plate 25 away from profile through arc-shaped guide hole 18 and guide rod 24, releasing the clamping of profile. The second motor is started again, causing feeding mechanism 2 to move resin profile toward clamping assembly again, pushing the cut resin profile out of clamping assembly. When resin profile moves between the two clamping assemblies again, the next clamping and cutting action can be performed.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
