Description

Technical Field

[0001] This invention belongs to the field of cutting tool technology, specifically a continuous feeding cutting device for processing plastic steel profiles. Background Technology

[0002] In the field of PVC profile processing in industries such as construction and home furnishing, cutting equipment is a key production equipment. Its adaptability and feeding efficiency directly determine the production capacity and product quality of the production line. As the market demand for personalized and diversified PVC profiles increases, the specifications and parameters of the profiles are becoming more and more abundant, which puts forward higher requirements for processing accuracy and the continuity of mass production.

[0003] Most devices employ manual feeding or simple conveyor belt transport, lacking effective profile straightening mechanisms. Manual feeding is heavily influenced by operator experience and pace, making it difficult to ensure the neatness and tightness of profile arrangement. This often results in disordered phenomena such as profile stacking and misalignment, hindering subsequent pushing and cutting processes and requiring additional manual reorganization, increasing labor costs and production cycles. Even with less automated conveyor belt transport devices, the lack of precise limiting and guiding structures makes the profiles susceptible to deviation due to vibration and friction during transport, preventing them from forming a tightly packed transport state. This disordered and loose feeding mode not only reduces feeding efficiency but also leads to significant length errors in the cut profiles, affecting the accuracy of subsequent assembly processes and wasting raw materials. Therefore, this application designs a continuous feeding cutting device for processing PVC profiles to solve the above problems. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing technologies and proposes a continuous feeding cutting device for processing PVC profiles; this invention is achieved through the following technical solution:

A height-adjustable pusher plate is connected to the side of the pusher slider near the support feeding seat. A discharge limiting component is provided on the support feeding seat, and a pusher arranging component is provided on the transfer feeding seat. The pusher arranging component includes a lifting feeding block slidably connected to the transfer feeding seat. A first electric pusher plate is provided at the upper end of the lifting feeding block, and multiple rubber columns are equidistantly spaced at the top of the first electric pusher plate. Support shafts that abut against and support the lifting feeding block are provided at both ends of the rubber columns. Friction shafts are provided at the side ends of the support shafts. A second electric pusher plate is installed in the lifting feeding block, and a friction abutment block that cooperates with the friction shaft is provided at the top of the second electric pusher plate.

[0006] Furthermore, a sliding groove is provided on the conveyor feeding seat, and multiple rollers are provided at equal intervals on the bottom of the lifting feeding block. The rollers abut against the bottom surface of the sliding groove, and a contact power supply groove that cooperates with the lifting feeding block is provided in the sliding groove; multiple sliding electric wheels are symmetrically provided on both sides of the lifting feeding block.

[0007] Furthermore, the discharge limiting assembly consists of a limiting support rod and an adjusting threaded rod. The end of the adjusting threaded rod is rotatably snapped onto the limiting support rod, and the adjusting threaded rod is threaded through the supporting feeding seat. The limiting support rod is provided with a sliding guide rod, which slides through the supporting feeding seat.

[0008] Furthermore, a limiting stop is slidably provided on the limiting support rod, and multiple pin holes are spaced apart on the limiting stop.

A sliding guide hole is vertically opened on the adjusting slider, and a first guide rod that cooperates with the sliding guide hole is provided on the push slider.

[0010] Furthermore, a linear motor sliding seat that mates with the slide rail is installed on the push slider.

[0011] Furthermore, a clamping seat is provided between the cutting box and the support mechanism, and a guide groove that matches the feed port of the cutting box is horizontally opened in the middle of the clamping seat.

[0012] Furthermore, multiple first electric push rods are equidistantly installed at the upper end of the feed chute, and the ends of the first electric push rods are provided with anti-slip rubber pads. Multiple second electric push rods are provided at the side end of the feed chute, and the ends of the multiple second electric push rods are provided with an anti-slip support plate.

[0015] The beneficial effects of this invention compared to the prior art are as follows:

[0016] 1. This invention utilizes the cooperation of a support feeding seat and a transmission feeding seat. Multiple support feeding seats are spaced apart to form a continuous conveying path. The lifting feeding block of the transmission feeding seat moves smoothly with the help of sliding electric wheels and rollers, thereby realizing the function of continuous profile feeding. Furthermore, through the linkage of the push slider and the discharge limiting component, the push plate of the push slider can be adjusted to adapt to profiles of different widths via the first transmission screw. The limiting stop bar of the discharge limiting component can adjust the spacing to limit profile deviation. At the same time, the rubber column achieves the switching between fixed support and rotational pushing through the cooperation of friction abutment and friction shaft, which facilitates the neat arrangement and precise conveying of profiles, thereby realizing the function of adapting and orderly conveying multiple specifications of profiles.

[0017] 2. This invention utilizes the cooperation between the clamping seat and the cutting saw table. The first and second electric push rods of the clamping seat fix the profile from the top, bottom, and sides. The pneumatic telescopic rod of the cutting saw table is further limited by rubber abutment blocks. The saw kerf groove provides a stable movement path for the cutting saw blade, adapting to the cutting needs of different profile specifications and improving the accuracy of cutting positioning, thereby achieving high-precision cutting. Furthermore, through the cooperation between the first transmission seat and the discharge inclined plate, the cut profile can be smoothly transported to the discharge area, and automatic discharge can be achieved with the help of the inclined structure. The etching table can pre-mark the cutting position to ensure cutting consistency, improving the continuity of overall processing and discharge, thereby achieving efficient continuous processing. Ultimately, this invention solves the problems of limited compatibility with existing plastic steel profile cutting devices and disordered and insufficient compactness of material feeding.

The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0031] See Figures 1 to 11This embodiment proposes a continuous feeding cutting device for processing PVC profiles, including a cutting box 1 and a support mechanism. The support mechanism consists of multiple spaced-apart support feeding seats 3, with a transfer feeding seat 5 installed between two adjacent support feeding seats 3. A clamping seat 2 is provided between the cutting box 1 and the support mechanism. A slide rail 4 is provided on one side of the support mechanism, and a push slider 6 is provided on the slide rail 4. A linear motor sliding seat that cooperates with the slide rail 4 is installed on the push slider 6.

The inner side of the discharge port of the cutting box 1 is provided with a first transmission seat 10, and the inner side of the inlet of the cutting box 1 is provided with a second transmission seat 12. A discharge ramp 9 is installed at an inclination between the first transmission seat 10 and the cutting saw table 8. A discharge groove is opened at the end of the discharge ramp 9 and located at the cutting box 1. The supporting feeding seat 3 is provided with a discharge limiting component, and the conveying feeding seat 5 is provided with a pushing and arranging component. Multiple supporting feeding seats 3 and conveying feeding seats 5 cooperate with each other to realize continuous feeding of profiles. The pushing slider 6 can move along the slide rail 4 to push the profile into the cutting box 1. The etching stage 11 can be pre-marked for cutting. The placement of the material discharge ramp 9 and the discharge chute enables automatic material discharge after cutting, effectively improving the continuity and efficiency of processing. A saw kerf groove 13 is provided in the middle of the cutting saw table 8, and two pneumatic telescopic rods are horizontally mounted on the cutting saw table 8, with rubber abutment blocks at the ends of the pneumatic telescopic rods. The saw kerf groove 13 provides movement space for the cutting saw blade, and the pneumatic telescopic rods are fixed to the profile by the rubber abutment blocks to prevent cutting deviation. Both the first transmission seat 10 and the second transmission seat 12 are equipped with motor-driven rotating feeding rollers, and multiple support rollers are rotatably mounted at intervals on the supporting feeding seat 3. The feeding rollers and the support... The support rollers reduce friction during profile conveying, ensuring smooth transmission. The clamping seat 2 has a horizontally opened guide groove in the middle that matches the feed inlet of the cutting box 1. Multiple first electric push rods 24 are installed at equal intervals at the upper end of the guide groove. The ends of the first electric push rods 24 are provided with anti-slip pads. Multiple second electric push rods 25 are provided at the side end of the guide groove. The ends of the multiple second electric push rods 25 are provided with an anti-slip support plate. The first electric push rods 24 press the profile from above, and the second electric push rods 25 are positioned from the side through the anti-slip support plate. The double fixation ensures that the profile is accurately positioned when it enters the cutting box 1, avoiding cutting deviation.

[0032] As a preferred option, such as Figures 4 to 9As shown, a drive motor 23 is installed in the push slider 6. A first drive screw 14 is provided on the motor shaft of the drive motor 23. The first drive screw 14 is coaxially fixed to the motor shaft. An adjusting slider 16 is threaded through the first drive screw 14. A sliding guide hole is vertically opened on the adjusting slider 16. A first guide rod 15 that cooperates with the sliding guide hole is provided on the push slider 6. A push plate 17 is bolted to the side end of the adjusting slider 16. The drive motor 23 drives the first drive screw 14 to move the adjusting slider 16 along the first guide rod 15. The position of the push plate 17 can be adjusted according to the width of the profile to adapt to the pushing requirements of different specifications of profiles. The drive motor 23 is a Panasonic MSMD series servo motor.

[0033] The material discharge limiting assembly consists of a limiting support rod 7 and an adjusting threaded rod 18. The end of the adjusting threaded rod 18 is rotatably snapped onto the limiting support rod 7, and the adjusting threaded rod 18 is threaded through the supporting feeding seat 3. The limiting support rod 7 is provided with a sliding guide rod 19, which slides through the supporting feeding seat 3. Rotating the adjusting threaded rod 18 can adjust the lateral position of the limiting support rod 7. With the guiding action of the sliding guide rod 19, the position of profiles of different lengths can be limited to prevent the profiles from shifting during feeding. Two limiting stops 20 are slidably provided on the limiting support rod 7. Multiple pin holes 22 are spaced apart on each limiting stop 20. Limiting pins 21 that match the pin holes 22 are inserted into the limiting support rod 7. The limiting stops 20 slide along the limiting support rod 7 and are fixed by the limiting pins 21. The initial feeding position can be adjusted according to the profile width to achieve stable alignment of the profiles and feeding them into the cutting box 1.

[0034] As a preferred option, such as Figures 9 to 11As shown, the pushing and arranging assembly includes a lifting feeding block 26. A sliding groove is provided on the conveying and loading seat 5, and the lifting feeding block 26 slides within the sliding groove. Multiple rollers 34 are equidistantly arranged at the bottom of the lifting feeding block 26, and the rollers 34 abut against the bottom surface of the sliding groove. An abutment power supply groove is provided in the sliding groove to cooperate with the lifting feeding block 26. Multiple sliding electric wheels 27 are symmetrically arranged on both sides of the lifting feeding block 26. The rollers 34 and sliding electric wheels 27 reduce the moving resistance of the lifting feeding block 26, and the abutment power supply groove ensures continuous power supply during its movement, achieving stable transmission and lifting of the profile. A first electric push plate 28 is provided at the upper end of the lifting feeding block 26, and the top of the first electric push plate 28 is equidistantly spaced... There are multiple rubber columns 29; the first electric push plate 28 can lift the profile to adjust its height, and the rubber columns 29 avoid rigid contact with the profile to prevent surface damage, while increasing friction to prevent slippage; the two ends of the rubber columns 29 are provided with support shafts 30 that abut against the lifting feeding block 26, and the side ends of the support shafts 30 are provided with friction shafts 31. The lifting feeding block 26 is equipped with a second electric push plate 33, and the top of the second electric push plate 33 is provided with a friction block 32 that cooperates with the friction shaft 31; the second electric push plate 33 pushes the friction block 32 to contact the friction shaft 31, and controls the rotation of the rubber columns 29 through friction, thereby achieving stable support of the rubber columns 29 in the fixed state and pushing and unloading of the rubber columns 29 in the rotating state. During the push, the alignment force between the profiles pushes the end profile away from the lifting feeding block 26, which can realize the close arrangement and conveying of the profiles, which is convenient for subsequent feeding and transmission and clamping and fixing during cutting; the first electric push plate 28 and the second electric push plate 33 are both variant components with electric push rods on the inner side. The electric push rods are all Limtech LAP series electric push rods, and the sliding electric wheel 27 is a 100U type drive wheel.

[0035] In this embodiment, the present invention also proposes a method for using a continuous feeding cutting device for processing PVC profiles, comprising the following steps:

[0036] Step 1: First, assemble the components according to requirements and install the corresponding control consoles for each component. Then, connect the power supply to the device. Before operation, the operator precisely adjusts the discharge limiting component according to the width and length specifications of the plastic steel profile to be processed: rotate the adjusting threaded rod 18, and under the guiding and limiting action of the sliding guide rod 19, drive the limiting support rod 7 to move laterally along the supporting feeding seat 3 until it reaches the preset position suitable for the profile length. Then slide the two limiting stops 20 to match the spacing with the profile width, insert the limiting pin 21 and fix it with the corresponding pin hole 22 to form a regular feeding channel and prevent the profile from shifting or misaligning during transmission. After placing the profiles to be processed in batches on the support rollers of the supporting feeding seat 3, start the drive system of the transmission feeding seat 5. The lifting feeding block 26 moves smoothly along the sliding groove under the drive of the sliding electric wheels 27 on both sides, and the bottom roller 34 is significantly lowered to the bottom surface of the sliding groove. The frictional resistance ensures smooth movement; the contact power supply groove in the sliding groove is in continuous contact with the conductive contact of the lifting feeding block 26 to ensure a stable power supply during movement; when the lifting feeding block 26 moves to the bottom of the profile, the first electric push plate 28 lifts upward, causing the top rubber column 29 to make close contact with the bottom of the profile; at this time, the second electric push plate 33 pushes the friction block 32 to fit tightly with the friction shaft 31 on the side of the support shaft 30, locking the rubber column 29 through frictional force, so that it is in a fixed state, achieving stable support for the profile; after the profile is supported in place, the second electric push plate 33 drives the friction block 32 to disengage from the friction shaft 31, and the rubber column 29 returns to a free rotation state. At this time, the profiles conveyed subsequently continue to move forward, generating a thrust (i.e., alignment blocking force) on the profiles supported in front. Under the action of this thrust, the profiles in front disengage from the lifting feeding block 26 and fit tightly on the transmission path of the support feeding seat 3, completing the material loading and alignment;

[0037] Step two: After the profile is shaped, it enters the pushing and positioning stage. This stage uses an automated adjustment and double-fixing mechanism to ensure the profile accurately enters the cutting area. Driven by a linear motor sliding seat, the pushing slider 6 moves along the slide rail 4 towards the profile, while simultaneously adaptively adjusting according to the profile width. The drive motor 23 starts and drives the first drive screw 14 to rotate. The adjusting slider 16 moves laterally along the screw under the guidance of the first guide rod 15, causing the bolt-connected pushing plate 17 to adjust to a position perfectly matching the profile width. Subsequently, the pushing slider 6 continues to move, smoothly pushing the neatly arranged profile into the guide groove of the clamping seat 2 via the pushing plate 17. The guide groove serves as the entry point for the profile into the cutting area. The transition channel of the cutting box 1 enables multi-dimensional positioning and fixing of the profile: multiple first electric push rods 24 at the upper end of the guide groove extend synchronously, and the anti-slip pads at the ends of the first electric push rods 24 are in close contact with the upper surface of the profile, pressing the profile firmly from the vertical direction to prevent it from moving up and down; multiple second electric push rods 25 at the side end of the guide groove work together to push the anti-slip support plate, pressing the profile firmly from the horizontal direction to ensure that the profile axis is consistent with the cutting direction; the double fixing structure effectively offsets the inertial force during the pushing process and the vibration during subsequent cutting, preventing the profile from shifting position and providing a guarantee for precise cutting; after positioning, the guide groove of the clamping seat 2 is precisely connected with the feed port of the cutting box 1, preparing the profile to enter the cutting area;

[0038] Step 3: After positioning and fixing, the profile enters the cutting box 1, and the cutting system is started for automated cutting. First, the motor on the second transmission seat 12 drives the feeding roller to rotate, smoothly conveying the profile to the preset cutting position on the cutting saw table 8. The two pneumatic telescopic rods on the cutting saw table 8 extend synchronously, and the rubber abutment blocks at their ends symmetrically abut against the profile from both sides. The rubber material avoids scratching the profile surface and enhances friction, preventing the profile from shifting during the cutting process. At the same time, the etching stage 11 at the top of the cutting box 1 starts, accurately marking the cutting line on the profile surface according to the preset cutting parameters, providing a clear cutting reference for the cutting saw blade, and further improving the cutting accuracy. Precision: The cutting saw blade moves along the saw kerf groove 13 in the middle of the cutting saw table 8. The length and width of the saw kerf groove 13 are adapted to the movement trajectory of the saw blade, ensuring that the saw blade is not interfered with during the cutting process. During the cutting process, the saw blade rotates at high speed and moves smoothly along the cutting line to complete the precise cutting of the profile. During this process, the feeding roller of the second transmission seat 12 slowly conveys the profile according to the cutting progress to ensure the continuity of the cutting. The debris generated by the cutting falls into the bottom of the cutting box 1 through the saw kerf groove 13, and the staff can clean the debris in the box regularly. After the cutting is completed, the pneumatic telescopic rod is retracted and the rubber abutment block is detached from the profile, preparing for the discharge of the cut profile.

[0039] Step four: After cutting, the profiles enter the discharge and collection stage, realizing automated output of finished products and equipment cycle operation; the motor on the first transmission seat 10 drives the feeding roller to rotate, conveying the cut profiles from the cutting saw table 8 to the discharge ramp 9; the discharge ramp 9 is inclined, using gravity to guide the profiles to slide downwards along the plate surface, and the wear-resistant coating on the surface of the ramp reduces friction between the profiles and the plate surface, avoiding surface scratches; after the profiles slide to the end of the discharge ramp 9, they are discharged to the outside of the equipment through the discharge chute opened in the cutting box 1. Operators can place a collection box under the discharge chute to achieve centralized collection of finished products; discharge is complete. Afterwards, all components of the equipment automatically reset: the push slider 6 returns to its initial position along the slide rail 4, the first electric push rod 24 and the second electric push rod 25 retract, and the clamping seat 2 is released from fixation; the cutting saw blade returns to the initial position of the saw kerf groove 13, and the pneumatic telescopic rod retracts; the lifting feeding block 26 returns to the feeding area, ready for the lifting and transmission of the next batch of profiles; at the same time, the discharge limit component maintains its current adjustment state, and if it is necessary to switch the processing profile specifications, the adjustment steps in the feeding preparation stage can be repeated; the entire equipment achieves continuous production through the coordinated reset and cyclic operation of each component, greatly improving processing efficiency and reducing the time loss caused by manual intervention.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
