Description

Technical Field

[0001] The invention relates to the technical field of PVC foam profile cutting equipment, in particular to a PVC foam profile cutting equipment. Background Art

[0002] PVC foam profiles account for a large proportion in the building materials industry. They can be divided into soft PVC foam profiles and hard PVC foam profiles according to their softness and hardness. They can be divided into PVC crust foam boards and PVC free foam boards according to the production process. They can be divided into PVC transparent boards and PVC foam profiles according to transparency and opacity.

[0003] PVC foam profiles are made from PVC and feature a honeycomb mesh structure. They are waterproof, flame-retardant, acid- and alkali-resistant, insect-resistant, lightweight, heat-insulating, sound-insulating, and shock-absorbing.

However, existing PVC foam cutting equipment can only cut finished PVC foam profiles and cannot be applied to PVC foam profile production lines, making them difficult to meet the demands of continuous production.

[0044] The present invention provides a PVC foam profile cutting device. To make the objectives, technical solutions, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention.

[0045] like Figure 1 and Figure 2 As shown, the present invention provides a PVC foam profile cutting device, comprising a traction device 1, a cutting device 2 and a blanking device 3 which are sequentially arranged along the traveling direction of the PVC foam profile.

[0046] The traction device 1 provides traction for the PVC foam profiles throughout the PVC foam profile production line. In practice, the traction device 1 can be installed adjacent to the PVC foam profile cooling device (not shown) in existing PVC foam profile production lines. The PVC material extruded from the extruder is shaped into a PVC foam profile by a shaping machine. After cooling in the PVC foam profile cooling device, the shaped PVC foam profile is continuously drawn to the traction device 1, which then draws it to the cutting device 2 for cutting.

[0047] Among them, the cutting device 2 includes a cutting platform 201, a first driving mechanism 202 for driving the cutting platform 201 to move back and forth along the traveling direction of the PVC foam profile, a lifting saw blade 203 that can shuttle on the cutting platform 201, a second driving mechanism 204 for driving the lifting saw blade 203 to move up and down, and a third driving mechanism 205 for driving the lifting saw blade 203 to rotate at high speed.

[0048] Specifically, the height of the cutting platform 201 is the same as the height of the traction surface of the traction device 1, so that the PVC foam profile on the traction device 1 can be continuously pulled onto the cutting platform 201 for cutting. Furthermore, a mounting plate 4 for mounting the third drive mechanism 205 can be provided below the cutting platform 201. In a specific implementation, a drive motor can be used as the third drive mechanism 205, so that the lifting saw blade 203 can be directly mounted on the output shaft of the third drive mechanism 205.

[0049] The lifting saw blade 203 is used to cut the continuously produced PVC foam profiles so that the PVC foam profiles can be cut into specified lengths according to usage requirements. Furthermore, in order to enable the lifting saw blade 203 to extend upward from the cutting platform 201 during the cutting operation, a second drive mechanism 204 can be fixed below the cutting platform 201, and the second drive mechanism 204 can be a telescopic cylinder. When the second drive mechanism 204 is a telescopic cylinder, the extended end of the piston rod of the second drive mechanism 204 is connected to the bottom of the mounting plate 4. In this way, when the second drive mechanism 204 is in operation, the mounting plate 4 can move up and down, thereby allowing the lifting saw blade 203 connected to the output shaft of the third drive mechanism 205 to extend upward from the cutting platform 201 during the cutting operation.

[0050] Furthermore, the bottom of the cutting platform 201 is also connected to a mounting frame 5 for installing the second drive mechanism 204, so that the second drive mechanism 204 and the mounting plate 4 connected to the second drive mechanism 204 can move together with the cutting platform 201, thereby ensuring that the high-speed rotating lifting saw blade 203 can move with the cutting platform 201 during operation.

[0051] Furthermore, the first drive mechanism 202 can be a telescopic cylinder, with the piston rod of the first drive mechanism 202 extending horizontally outward and connected to the cutting platform 201. During the cutting operation, the first drive mechanism 202 can pull the cutting platform 201, so that the cutting platform 201 and the lifting saw blade 203 in the process of cutting can move at the same speed as the PVC foam profile, allowing the lifting saw blade 203 to successfully cut the PVC foam profile at the designated location. After completing a round of cutting, the cutting platform 201 returns to its initial position.

[0052] The unloading device 3 includes an unloading platform 301 , a fifth driving mechanism 302 for driving the unloading platform 301 to rotate, two first travel switches 303 for detecting whether the PVC foam profile is in place, and a material receiving platform 304 arranged below the unloading platform 301 .

[0053] Specifically, the height of the unloading platform 301 is the same as that of the cutting platform 201, so that the cut PVC foam profile can be smoothly moved to the unloading platform 301 under the boosting effect of the uncut PVC foam profile (the boosting force is provided by the traction device 1).

[0054] Furthermore, the unloading device 3 also includes a bracket 6 for installing the unloading platform 301. In a specific implementation, the two ends of the unloading platform 301 can be rotatably connected to the bracket 6, and the fifth driving mechanism 302 can be a driving motor, so that the motor can directly drive the unloading platform 301 to rotate relative to the bracket 6.

[0055] Furthermore, the first travel switch 303 is arranged above the unloading platform 301 along the traveling direction of the PVC foam profile, and the first travel switch 303 can be fixed on the bracket 6, so that when the unloading platform 301 rotates, the first travel switch 303 will not rotate with the unloading platform 301, thereby simplifying the installation structure of the first travel switch 303.

[0056] Furthermore, among the two first travel switches 303 , the one close to the cutting device 2 is the first travel switch A, and the one far away from the cutting device 2 is the first travel switch B.

[0057] After each cutting operation by the lifting saw blade 203, the cut PVC foam profile, propelled by the uncut PVC foam profile, moves onto the unloading platform 301. As the cut PVC foam profile moves on the unloading platform 301, its front end first contacts the first travel switch A. Once the front end of the cut PVC foam profile contacts the first travel switch A, the first travel switch A is triggered, causing the first drive mechanism 202, the second drive mechanism 204, and the third drive mechanism 205 to simultaneously receive operating signals, thereby enabling the lifting saw blade 203 to perform the next round of cutting operations on the continuously produced PVC foam profile. Furthermore, to ensure that the length of the PVC foam profile remains consistent after each cut, when the cutting platform 201 returns to its initial position, the lateral spacing between the contacts of the first travel switch A and the lifting saw blade 303 should be the length of the cut PVC foam profile.

[0058] During the next round of cutting operation of the lifting saw blade 203, the rear end of the PVC foam profile obtained by the previous round of cutting is in contact with the rear end of the PVC foam profile that has not been finished cutting, so the PVC foam profile obtained by the previous round of cutting can still continue to move. When its front end contacts another first travel switch 303 (for the sake of convenience of description, the first travel switch 303 is recorded as the first travel switch B), the first travel switch B is triggered, and the fifth drive mechanism 302 can receive the working signal, so that the unloading platform 301 rotates, and the cut PVC foam profile on the unloading platform 301 falls onto the receiving platform 304, thereby realizing the unloading of the PVC foam profile. Furthermore, the distance between the two contacts of the first travel switch 303 is smaller than the length of the cut PVC foam profile. In this way, before a new round of PVC foam profile cutting operation is carried out, the cut PVC foam profile can be unloaded first, and the front end of the uncut PVC foam profile will contact the first travel switch A and trigger the first travel switch A, thereby enabling the cutting length of the PVC foam profile to be accurately controlled.

[0059] The present invention is provided with a cutting device 2 that works in conjunction with the traction device 1. When the cutting device 2 is working, the cutting platform 201 and the saw blade can move together with the PVC foam profile continuously pulled out by the traction device 1. While successfully completing the cutting of the specified position of the PVC foam profile, the continuously produced PVC foam profile can also be cut, thereby meeting the needs of continuous production operations of PVC foam profiles. The present invention is also provided with a blanking device 3. When the blanking device 3 is working, the blanking platform 301 can rotate and complete the unloading of the cut PVC foam profile. At the same time, by using the first stroke switch set on the blanking device 3 and triggering the first stroke switch by the cut PVC foam profile, the cutting operation and the unloading operation of the PVC foam profile can be coordinated with each other, without manual operation, and the degree of automation of the production operation is higher. Moreover, since the PVC foam profile can be automatically unloaded after cutting, the production efficiency of the PVC foam profile can be significantly improved.

[0060] like Figure 3 、 Figure 4 、 Figure 6 as well as Figure 7 As shown, in another preferred embodiment of the present invention, multiple fifth drive mechanisms 302 are provided, and the fifth drive mechanism 302 is a telescopic cylinder. Furthermore, the unloading device 3 also includes a side frame 7 (which can be part of the aforementioned bracket 6), and a support plate 8 is provided on the side frame 7. When the unloading platform 301 is not rotating, the bottom of one side of the unloading platform 301 contacts the support plate 8, while the bottom of the other side of the unloading platform 301 is supported by the piston rod of the fifth drive mechanism 302. The fifth drive mechanism 302 is tilted and parallel to the bottom of the unloading platform 301. This allows the unloading platform 301 to remain stable and horizontal when not rotating, allowing the cut PVC foam profile to move smoothly onto the unloading platform 301.

[0061] like Figure 6 and Figure 7 As shown, in order to enable the unloading platform 301 to rotate and unload materials during the unloading operation of the unloading device 3, in the specific implementation of this embodiment, the extended end of the piston rod of the fifth drive mechanism 302 is simultaneously hinged upward to the bottom of the unloading platform 301, and the lower end of the fifth drive mechanism 302 is simultaneously hinged to the lower portion of the side frame 7. In this way, when the piston rod of the telescopic cylinder is extended or retracted, the unloading platform 301 can rotate relative to the side frame 7. After the piston rod of the telescopic cylinder is retracted, the unloading platform 301 in a horizontal state can rotate toward the side where the receiving platform 304 is located, so that the PVC foam profile on the unloading platform 301 falls onto the receiving platform 304, thereby realizing the unloading of the PVC foam profile.

[0062] like Figure 6As shown, further, a support frame 9 for supporting the material receiving platform 304 is provided under the material receiving platform 304, and a buffer pad 10 is provided on the contact surface between the support frame 9 and the bottom of the material receiving platform 304, so as to improve the impact resistance of the material receiving platform 304 and avoid the cut PVC foam profile falling on the material receiving platform 304 and causing deformation of the material receiving platform 304.

[0063] like Figure 7 As shown, further, a magnetic seat 12 is provided on the upper part of the side frame 7, and the magnetic seat 12 is used to install the first limit switch 303. The selection of the magnetic seat 12 is convenient for the operator to adjust the distance between the two first limit switches 303 and the lateral distance between the first limit switch 303 and the lifting saw blade 203 according to production operation requirements.

[0064] Furthermore, the magnetic seat 12 includes a seat body 121 arranged on the upper part of the side frame 7, a vertical rod 122 arranged on the seat body 121, a sleeve body 123 movably sleeved on the vertical rod 122, and a mounting rod 124 horizontally movably penetrated through the sleeve body 123.

[0065] Among them, the first travel switch 303 is set at one end of the mounting rod 124 above the unloading platform 301. After the mounting rod 124 passes through the sleeve 123, it can move in a direction perpendicular to the moving direction of the PVC foam profile, so that the position of the first travel switch 303 can be adjusted according to the width of the PVC foam profile; and the sleeve 123 can move up and down along the vertical pole 122, so that when the mounting rod 124 with the first travel switch 303 is fixed on the sleeve 123, the height of the first travel switch 303 can be adjusted so that when the PVC foam profile moves to the first travel switch 303, the first travel switch 303 can be triggered smoothly.

[0066] Furthermore, the first travel switch 303 is a roller travel switch, and the rotating arm of the roller travel switch is arranged downward and connected to a stopper 13. When the cut PVC foam profile passes through the first travel switch 303, the front end of the PVC foam profile pushes the stopper 13, causing the rotating arm to rotate, thereby quickly triggering the first travel switch 303.

[0067] like Figure 3 and Figure 4 As shown, in a specific embodiment of the present invention, the PVC foam profile cutting device further includes a housing 11. The traction device 1 and the cutting device 2 are disposed within the housing 11, thereby reducing production safety hazards. Furthermore, first openings 14 suitable for passage of PVC foam profiles are provided on both sides of the housing 11. Therefore, the arrangement of the housing 11 does not affect the production of PVC foam profiles, nor does it affect the normal cutting and blanking operations.

[0068] like Figure 4 As shown, the pulling end of the traction device 1 is further provided with a PVC foam profile guide mechanism, which is arranged on the chassis 11 where the first opening 14 is located. Specifically, the guide mechanism includes two guide rollers 15 with adjustable distance. Through the guidance of the guide rollers 15, the cooled PVC foam profile can enter the traction device 1 in the correct direction of travel.

[0069] like Figure 4 、 Figure 5 as well as Figure 8 As shown, further, the traction device 1 includes an upper traction device and a lower traction device; the upper traction device and the lower traction device both include a sixth driving mechanism 101, an active roller 102 transmission-connected to the sixth driving mechanism 101, a driven roller 103 arranged parallel to the active roller 102, and a traction crawler 104 with large traction force wound around the active roller 102 and the driven roller 103.

[0070] like Figure 8 As shown, in a specific implementation, the sixth drive mechanism 101 is selected to be a drive motor, and a transmission mechanism is also provided between the drive mechanism and the driving rollers 102 of the upper and lower traction devices. This transmission mechanism specifically includes a driving sprocket 105 coaxially arranged with the output shaft of the sixth drive mechanism 101, a driven sprocket 106 coaxially arranged with the driving roller 102, and a transmission chain 107 wound around the driving sprocket 105 and the driven sprocket 106. Compared to other transmission methods, the chain transmission has a higher load capacity, especially for large traction devices 1, and can ensure the traction device 1 can perform normally.

[0071] like Figure 8 As shown, the upper traction device further includes a frame 108 for mounting the active roller 102 and the driven roller 103; a seventh drive mechanism 16 is connected to both ends of the frame 108; the seventh drive mechanism 16 is used to drive the upper traction device to rise and fall. In a specific implementation, the seventh drive mechanism 16 can be a telescopic cylinder, and the extended end of the piston rod of the seventh drive mechanism 16 is downwardly connected to the frame 108. In this way, the height of the upper traction device can be adjusted by extending and retracting the telescopic cylinder, so that the distance between the traction track 104 at the bottom of the upper traction device and the traction track 104 at the top of the lower traction device can be set according to the thickness of the PVC foam profile, so that the PVC foam profile can be pulled onto the cutting device 2 under the pressure of the traction tracks 104 on both sides.

[0072] like Figure 4 、 Figure 5 and Figure 8As shown, further, sliders 17 connected to the seventh drive mechanism 16 are provided at both ends of the frame 108. In a specific embodiment, the top of the slider 17 is connected to the extended end of the piston rod of the seventh drive mechanism 16, and a partition plate 18 located within the chassis 11 is fixed between the traction device 1 and the cutting device 2. The partition plate 18 and the chassis 11 can be used to fix the seventh drive mechanism 16, so that the upper traction device can be flexibly suspended above the lower traction device via the seventh drive mechanism 16 on both sides. Furthermore, the partition plate 18 and the chassis 11 are both provided with slides 19 that cooperate with the slider 17, so that the upper traction device can be smoothly raised and lowered during height adjustment.

[0073] like Figure 9 As shown, further, rollers 20 are provided on both sides of the bottom of the cutting platform 201, and guide rails 21 are fixed on both sides of the interior of the chassis 11 to cooperate with the rollers 20. Preferably, the guide rails 21 can be provided with guide grooves that cooperate with the rollers 20, so that the cutting platform 201 can move smoothly under the action of the first driving mechanism 202, thereby ensuring that the cutting effect of the PVC foam profile is not deteriorated and the cross-section of the PVC foam profile after cutting can be flat.

[0074] like Figure 4 and Figure 9 As shown, further, a transition platform 22 is provided between the cutting platform 201 and the unloading platform 301, and the transition platform 22 is fixedly connected to the cutting platform 201, and the height of the transition platform 22, the cutting platform 201 and the unloading platform 301 are the same. When the lifting saw blade 203 cuts the PVC foam profile, the transition platform 22 fixedly connected to the cutting platform 201 can be extended from the first opening 14 and approach the unloading platform 301 under the action of the first driving mechanism 202. This can ensure that the cut PVC foam profile is supported by a sufficient distance during the movement, so that the PVC foam profile can smoothly move to the unloading platform 301.

[0075] like Figures 9 to 12 As shown, in other preferred embodiments provided by the present invention, the cutting device 2 also includes a swing plate 23 arranged below the cutting platform 201, which has the same function as the aforementioned mounting plate 4, and can be used to install the third drive mechanism 205 and enable the high-speed rotating lifting saw blade 203 to be lifted and lowered.

[0076] like Figure 9 、 Figure 11 and Figure 12 As shown, specifically, the third driving mechanism 205 is fixed at the bottom of the swing plate 23, and the first shaft cylinder 24 and the second shaft cylinder 25 are fixed at both ends of the swing plate 23 respectively.

[0077] A fixed shaft 27 is disposed within the first shaft cylinder 24, and a vertical plate with a bearing seat 26 is connected to the bottom of the cutting platform 201. In a specific implementation, both ends of the fixed shaft 27 can be rotatably connected to the bearing seat 26, thereby causing the swing plate 23 to swing when the second shaft cylinder 25 moves up and down.

[0078] The second shaft cylinder 25 is provided with a rotating shaft 28 that is in transmission connection with the third drive mechanism 205. The lifting saw blade 203 is mounted on the rotating shaft 28. When the third drive mechanism 205 is in operation, the rotating shaft 28 and the lifting saw blade 203 are rotated by a belt drive. In addition, the second drive mechanism 204 is disposed below and connected to the second shaft cylinder 25. When the second drive mechanism 204 is in operation, the second shaft cylinder 25 can move up and down under the action of the telescopic cylinder, thereby enabling the lifting saw blade 203 to move up and down.

[0079] Since both ends of the fixed shaft 27 can be rotatably connected to the aforementioned bearing seat 26 respectively, when the second shaft cylinder 25 moves up and down, the swing plate 23 can swing.

[0080] like Figure 11 As shown, further, in this preferred embodiment, the second drive mechanism 204 can be installed on the aforementioned mounting frame 5, and the mounting frame 5 is provided with a second limit switch 29. The second limit switch 29 is arranged above the swing plate 23 and can be used to prevent the swing plate 23 from swinging upward excessively. When the swing plate 23 swings upward and triggers the second limit switch 29, the second limit switch 29 can promptly feedback a signal to the second drive mechanism 204, so that the second drive mechanism 204 no longer performs the lifting operation.

[0081] like Figure 12 As shown, the cutting platform 201 is further provided with a second opening 30 suitable for the passage of the lifting saw blade 203; the PVC foam profile cutting device also includes a fourth drive mechanism 31 fixed above the second opening 30. The fourth drive mechanism 31 can be a telescopic cylinder, and a pressing mechanism 32 is provided below the fourth drive mechanism 31.

[0082] The pressing mechanism 32 includes a pressing rod 321 arranged in parallel and a connecting rod 322 connected to the pressing rod 321 , and the connecting rod 322 is connected to the piston rod of the fourth driving mechanism 31 .

[0083] Furthermore, the lifting saw blade 203 is relatively positioned between the two lower pressure rods 321. During actual operation, when the front end of the uncut PVC foam profile triggers the aforementioned first travel switch A, the fourth drive mechanism 31 can also receive a working signal, causing the lower pressure mechanism 32 to move downward and compress the PVC foam profile via the lower pressure rod 321. In this way, when the lifting saw blade 203 extends upward from the second opening 30 to perform the cutting operation, the PVC foam profile will not move freely relative to the cutting platform 201 (while under the action of the traction device 1 and the first drive mechanism 202, the PVC foam profile and the cutting platform 201 still move together), thereby improving the cutting effect of the PVC foam profile and ensuring that the cut surface of the PVC foam profile is smooth and free of obvious burrs.

[0084] Furthermore, the height of the connecting rod 322 is higher than the height of the lifting saw blade 203 when performing cutting operations, which ensures that there is enough space for the lifting saw blade 203 to cut the PVC foam profile after it moves upward.

[0085] like Figure 9 and Figure 12 As shown, the cutting platform 201 is further provided with an upper shield 33; the fourth drive mechanism 31 is disposed on the top of the upper shield 33, and openings 34 for passing the PVC foam profile are formed on both sides of the upper shield 33. Furthermore, curtains 35 are provided at the openings 34 to confine dust generated by the cutting operation within the upper shield 33, thereby improving the working environment.

[0086] like Figure 9 、 Figure 11 and Figure 12 As shown, in addition, a lower shield 36 corresponding to the upper shield 33 is provided at the bottom of the cutting platform 201. The lifting saw blade 203 is located in the lower shield 36, and an air inlet is provided at the bottom of the lower shield 36, and an air duct 37 is installed at the air inlet. In this way, the dust generated by the cutting operation can be introduced into the dust removal system through the air duct 37, further improving the working environment of the workshop.

[0087] like Figure 9 and Figure 10As shown, further, a limiting assembly 38 for limiting the position of the PVC foam profile is symmetrically provided on the cutting platform 201. The limiting assembly 38 is arranged on the cutting platform 201 between the upper baffle 33 and the partition plate 18, and includes a limiting piece 381 and a first adjustment plate 382 with a U-shaped hole; the limiting piece 381 can contact the two side surfaces of the PVC foam profile, so that when the PVC foam profile passes through, the PVC foam profile can be limited and will not deviate from the normal straight path during the movement, thereby ensuring that the PVC foam profile can be correctly cut; the first adjustment plate 382 is connected to the limiting piece 381, and a positioning rod 39 is provided on the cutting platform 201 to cooperate with the U-shaped hole of the first adjustment plate 382, ​​so that the first adjustment plate 382 and the limiting piece 381 can move, so that the distance between the limiting assemblies 38 can be adjusted according to the width of the PVC foam profile to be produced.

[0088] like Figure 3 and Figure 8 As shown, further, a sensing probe 40 is provided on the partition plate 18. Among existing PVC foam profile products, there is a type of plastic-aluminum co-extruded PVC foam profile. The aluminum in the plastic-aluminum co-extruded PVC foam profile is usually evenly spaced in the PVC substrate. The sensing probe 40 can sense the aluminum in the PVC substrate. Once the sensing probe 40 senses the aluminum, it transmits a signal to the control system of the device, causing the control system to count down. After the countdown ends, the cutting device 2 is controlled to perform the cutting operation. Thus, one machine has multiple uses, allowing the cutting device 2 to cut different types of PVC foam profiles produced continuously.

[0089] In addition, the countdown time can be set according to the travel speed and cutting requirements of the PVC foam profile, so that the length and structure of the plastic-aluminum co-extruded PVC foam profile remain the same after each cutting.

[0090] like Figure 8 As shown, the partition plate 18 is further provided with a height adjustment assembly 41, which includes two parallel second adjustment plates 411 and a mounting transverse plate 412 disposed below and fixedly connected to the second adjustment plates 411. The aforementioned sensing probe 40 is mounted on the mounting transverse plate 412. The second adjustment plates 411 and the first adjustment plate 382 operate under the same adjustment principle. Thus, by moving the second adjustment plates 411, the height of the sensing probe 40 can be adjusted according to the thickness of the PVC foam profile.

[0091] In summary, the present invention provides a PVC foam profile cutting device, which is provided with a cutting device that works in conjunction with a traction device. When the cutting device is working, the cutting platform and the saw blade can move together with the PVC foam profile continuously pulled out by the traction device. While successfully completing the cutting of the specified position of the PVC foam profile, the continuously produced PVC foam profile can also be cut, thereby meeting the needs of continuous production operations of PVC foam profiles. The present invention is also provided with a blanking device. When the blanking device is working, the blanking platform can rotate and the cut PVC foam profile is completed. At the same time, by using the limit switch set on the blanking device and triggering the limit switch by the cut PVC foam profile, the cutting operation and the blanking operation of the PVC foam profile can be coordinated with each other, without manual operation, and the degree of automation of the production operation is higher. Moreover, since the PVC foam profile can be automatically blanked after cutting, the production efficiency of the PVC foam profile can be significantly improved.

[0092] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the claims attached to the present invention.
