Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, and more particularly to a sandwich panel cutting device with a circular saw blade. Background Technology

[0002] Sandwich panels, also known as composite panels or sandwich panels, are a typical composite building material. As the name suggests, it resembles a sandwich, consisting of two metal panels on the top and bottom, and a core material in the middle, bonded together with a high-strength adhesive and cured under high temperature and pressure. After manufacturing, sandwich panels are generally cut into multiple sections according to the target dimensions. Cutting with a circular saw blade generates a significant amount of heat. The polymer core material (such as polyurethane or polystyrene) melts and burns when heated, producing toxic fumes and viscous molten substances. These molten substances adhere to the cut surfaces of the sandwich panels, sometimes even flowing back out and contaminating the surface, making them extremely difficult to clean and severely affecting the appearance and subsequent processing (such as sealing and bonding). Furthermore, the vibration, heat, or mechanical stress generated during cutting can damage the adhesive layer between the panels and the core material, leading to localized "delamination" or "separation" near the cut line. This not only affects the appearance of the produced sandwich panels but also severely weakens the overall strength and rigidity of the material. Air cooling is typically used to dissipate heat from the circular saw blade and the panels, but the cooling effect is poor and dust is easily generated. Summary of the Invention

[0003] In view of this, the present invention provides a sandwich panel cutting device that can directly contact the panel surface at the cut seam of the sandwich panel for cooling, thereby improving cooling efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solutions.

[0005] 1. A sandwich panel cutting device, comprising: Sandwich panel conveyor line, used to transport sandwich panels; The cutting mechanism is equipped with a circular saw blade for cutting sandwich panels; The clamping cooling mechanism includes two cooling clamps that can move up and down. The two cooling clamps are symmetrically arranged on both sides of the cut of the sandwich panel, and each cooling clamp is a rectangular cavity structure. After the sandwich panel conveyor line transports the sandwich panel to the cutting position, two cooling fixtures move down and fit against both sides of the sandwich panel cut. Coolant is introduced into the cooling fixtures. Then the cutting mechanism cuts the sandwich panel, and the heat of the sandwich panel is transferred to the cooling fixtures to reduce the temperature at the sandwich panel cut.

[0006] The clamping and cooling mechanism of this application not only compresses the two sides of the sandwich panel at the cut seam when the circular saw blade cuts the sandwich panel, reducing the probability that the adhesive layer between the metal panel and the core material will be damaged by vibration, heat, or mechanical stress generated during cutting, thus preventing local "delamination" or "separation" near the cut seam, but also, because it is attached to the two sides of the sandwich panel cut seam and uses a circulating coolant, it can directly and rapidly cool the surface of the sandwich panel, preventing the core material in the middle from melting and burning when heated, and producing toxic fumes and viscous melts, which would affect the quality of the sandwich panel after cutting.

[0007] 2. In addition to technical solution 1, it also includes: The clamp conveyor line is used to transport the clamping and cooling mechanism; After the sandwich panel is cut, the sandwich panel conveyor line transports the sandwich panel, and the clamping and cooling mechanism is driven by the clamping and cooling mechanism to move synchronously with the sandwich panel in order to extend the cooling time of the sandwich panel cut.

[0008] 3. Based on technical solution 2, the fixture conveying line includes: The annular slide groove includes an upper transverse slide groove, a right vertical slide groove, a lower transverse slide groove, and a left vertical slide groove that are connected in sequence. Four linear actuators are provided, each corresponding to one of the four grooves of the annular slide, and are used to drive the clamping and cooling mechanism to slide within the corresponding groove. When the sandwich panel conveyor line transports the sandwich panel, the linear driver corresponding to the lower transverse slide groove drives the clamping and cooling mechanism to move along the lower transverse slide groove until the clamping and cooling mechanism moves to the intersection of the lower transverse slide groove and the left vertical slide groove. The clamping and cooling mechanism releases the sandwich panel. The linear driver corresponding to the left vertical slide groove drives the clamping and cooling mechanism to move along the left vertical slide groove until the clamping and cooling mechanism moves to the intersection of the left vertical slide groove and the upper transverse slide groove. The linear driver corresponding to the upper transverse slide groove drives the clamping and cooling mechanism to move along the upper transverse slide groove, and so on, so that the clamping and cooling mechanism returns to the initial position and continues to clamp and cool the lower seam of the sandwich panel.

[0009] 4. Based on technical solution 2, two clamping and cooling mechanisms are provided. When one clamping and cooling mechanism moves with the sandwich panel, the other clamping and cooling mechanism is driven by the clamp conveyor line to return to the position of the sandwich panel to be cut, so that the clamping and cooling mechanism clamps and cools the lower cut seam of the sandwich panel. This cycle is repeated to speed up the cutting efficiency of the sandwich panel.

[0010] 5. Based on technical solution 2, two clamping and cooling mechanisms are provided, which are symmetrically arranged on the upper and lower sides of the sandwich panel; the sandwich panel conveying line is provided with a clearance roller conveyor for conveying the cut sandwich panel, which includes multiple rollers arranged in rows and movable up and down; when the clearance roller conveyor conveys the sandwich panel, the rollers move down in sequence along the conveying direction to avoid the clamping and cooling mechanisms that move synchronously with the sandwich panel.

[0011] 6. Based on technical solution 1, the clamping cooling mechanism further includes: A fixture cleaning assembly, including a cleaning brush, for cleaning the lower surface of a cooling fixture; As the cooling fixture moves away from the surface of the sandwich panel, the cleaning brush moves along the lower surface of the cooling fixture to clean the condensate and dust that have condensed on the lower surface of the cooling fixture.

[0012] 7. Based on technical solution 6, the clamping cooling mechanism further includes: The protective cover has two openable and closable half-covers; When the cleaning brush cleans the cooling fixture, the two half-covers close and cover the outside of the cooling fixture to keep out the dust; when the cooling fixture cools the sandwich panel, the two half-covers open to allow the cooling fixture to extend out of the protective cover.

[0013] 8. In addition to technical solution 1, it also includes: Saw blade cooling mechanism, used to cool the circular saw blade; After the circular saw blade finishes cutting the sandwich panel, the saw blade cooling mechanism cools the circular saw blade to reduce its temperature.

[0014] 9. Based on technical solution 8, the saw blade cooling mechanism includes: The cooling plate has a cooling chamber filled with coolant; The drive cylinder is connected to the cooling plate and is used to drive the cooling plate to move. When the circular saw blade returns to its original position, the drive cylinder drives the cooling plate to fit against the surface of the circular saw blade, so that the cooling plate can remove the heat from the circular saw blade.

[0015] 10. In addition to technical solution 9, it also includes: The saw blade braking mechanism includes a brake caliper and a brake pad. The brake pad is connected to the circular saw blade and can rotate with the circular saw blade. When the circular saw blade returns to its original position, the brake caliper stops the brake pad to stop the circular saw blade before the cooling plate cools it down. Attached Figure Description

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See Figure 1 and Figure 2 The sandwich panel cutting device in this embodiment is mainly used to cut sandwich panels and cool the cut seams to improve the quality of the cut sandwich panels. Combined with... Figure 1 The sandwich panel cutting device includes a support frame 1, a sandwich panel conveying line 2, a cutting mechanism 3, a clamping and cooling mechanism 4, a clamping and conveying line 5, a saw blade cooling mechanism 6, and a saw blade braking mechanism 7. The sandwich panel 8 is laid flat on the sandwich panel conveying line 2, which is used to transport the sandwich panel 8. The support frame 1 spans the sandwich panel conveying line 2. The cutting mechanism 3 is mounted on the support frame 1 and is equipped with a circular saw blade 34 for cutting the sandwich panel 8. Figure 10 After cutting, a slit a is formed between two adjacent sandwich panels 8. A clamping and cooling mechanism 4 is mounted on the support frame 1 to clamp and cool the slit a of the sandwich panels 8. A clamping conveyor line 5 is mounted on the support frame 1 to drive the clamping and cooling mechanism 4 to move synchronously with the sandwich panels 8. A saw blade cooling mechanism 6 is mounted on the support frame 1 and located at the starting point of the circular saw blade 34 to cool the circular saw blade 34. A saw blade braking mechanism 7 is positioned opposite the saw blade cooling mechanism 6 to stop the rotating circular saw blade 34.

[0029] When the sandwich panel conveyor line 2 transports the sandwich panel 8 to the cutting position, it stops transporting. The clamping and cooling mechanism 4 moves towards the panel surface of the sandwich panel 8 and presses the two sides of the panel 8 at the cutting position. After the circular saw blade 34 cuts the sandwich panel 8, it returns to the initial position. The saw blade braking mechanism 7 stops the rotating circular saw blade 34, and then the saw blade cooling mechanism 6 cools the circular saw blade 34 to prevent heat accumulation and high temperature. At the same time, the sandwich panel conveyor line 2 continues to transport the sandwich panel 8, and the clamping and cooling mechanism 4 moves synchronously with the sandwich panel 8 to extend the cooling time for the cut a. When the clamping and cooling mechanism 4 reaches its position, the clamping and cooling mechanism 4 returns to the initial position to clamp and cool the next cut a of the sandwich panel 8.

[0030] The clamping and cooling mechanism 4 in this embodiment can not only compress the two sides of the sandwich panel 8 at the cut a when the circular saw blade 34 cuts the sandwich panel, reducing the probability that the adhesive layer between the metal panel and the core material will be damaged by the vibration, heat or mechanical stress generated during cutting, thus preventing local "delamination" or "separation" near the cut a, but also rapidly cool the two sides of the sandwich panel 8 at the cut a, preventing the core material in the middle from melting and burning when heated, and producing toxic fumes and viscous melts, which would affect the quality of the cut sandwich panel.

[0031] See Figure 5 and Figure 6 In this embodiment, a set of two clamping and cooling mechanisms 4 is provided. These two clamping and cooling mechanisms 4 are symmetrically arranged on the upper and lower sides of the sandwich panel 8 and can move up and down. Using two clamping and cooling mechanisms 4 allows for simultaneous compression of the upper and lower surfaces of the sandwich panel 8, achieving the clamping purpose and reducing the vibration force experienced at the cut seam a during cutting. This further reduces the probability of localized "delamination" or "separation" of the sandwich panel 8 during cutting. Furthermore, both the upper and lower surfaces are cooled, lowering the temperature of the sandwich panel 8 and further improving the processing quality of the sandwich panel 8.

[0032] To avoid interference between the clamping and cooling mechanism 4, located below the sandwich panel conveyor line 2, and the sandwich panel conveyor line 2 during the movement of the sandwich panel 8, in conjunction with... Figure 2 and Figure 3 In this embodiment, the sandwich panel conveying line 2 is provided with a clearance roller conveyor 21 for conveying the cut sandwich panels. The clearance roller conveyor 21 includes a plurality of clearance roller assemblies arranged in rows. Each clearance roller assembly includes a clearance drive cylinder 212 and a roller 211. The clearance drive cylinder 212 is mounted on the support frame 1, and the roller 211 is connected to the telescopic rod of the clearance drive cylinder 212. When the clearance roller conveyor 21 conveys the sandwich panel 8, the clearance drive cylinder 212 drives the roller 211 to move downwards sequentially along the conveying direction to avoid the clamping and cooling mechanism 4 that moves synchronously with the sandwich panel 8.

[0033] See Figure 5 and Figure 6 The clamping and cooling mechanism 4 in this embodiment includes a clamp support 41, a clamp drive cylinder 42, and a cooling clamp 43. The clamp support 41 is located directly above the cut a of the sandwich panel 8, and a slit 411 is provided on the clamp support 41 to avoid the circular saw blade 34. Two cooling clamps 43 are provided, and the two cooling clamps 43 are symmetrically arranged on the left and right sides of the cut a of the sandwich panel. Each cooling clamp 43 is connected to the clamp support 41 through a set of clamp drive cylinders 42. Each cooling clamp 43 is a rectangular cavity structure filled with coolant. The cooling clamp 43 is provided with an inlet 431 and an outlet 432. The inlet pipe (not shown in the figure) can pass through the through hole on the clamp support 41 and connect to the inlet 431, and the outlet pipe (not shown in the figure) can pass through the through hole on the clamp support 41 and connect to the outlet 432.

[0034] After the sandwich panel conveyor line 2 transports the sandwich panel 8 to the cutting position, the two sets of clamp drive cylinders 42 respectively drive the two cooling clamps 43 to move down and fit against both sides of the cut a of the sandwich panel. Coolant is introduced into the cooling clamps 43 through the liquid inlet pipe, and the coolant flows out from the liquid outlet 432 of the cooling clamps 43. Subsequently, the circular saw blade 34 cuts the sandwich panel 8. During the cutting process, the heat of the sandwich panel 8 is transferred to the cooling clamps 43. The coolant in the cooling clamps 43 circulates continuously, improving the heat exchange efficiency of the sandwich panel 8 and ensuring that the temperature at the cut a of the sandwich panel does not become too high. In this embodiment, the cooling clamps 43 are designed as cavities and are filled with circulating coolant, which can directly cool the cut a of the sandwich panel 8, resulting in a better cooling effect compared to air cooling.

[0035] To prevent dust from adhering to the surface of the cooling fixture 43 due to condensation, combined with... Figure 5 and Figure 6 The clamping and cooling mechanism 4 in this embodiment also includes a protective cover drive cylinder 44, a protective cover 45, and a clamp cleaning assembly. The protective cover 45 is composed of two symmetrically arranged half-covers 451 on both sides of the clamp support 41. Each half-cover 451 is an L-shaped plate structure, and the clamp support 41 is a U-shaped structure. The two half-covers 451 and the clamp support 41 form a nearly closed cavity. Two protective cover drive cylinders 44 are provided and symmetrically installed on the clamp support 41. Each protective cover drive cylinder 44 corresponds to one half-cover 451 and can drive the corresponding half-cover 451 to move left and right. The two half-covers 451 are opened and closed under the drive of the protective cover drive cylinders 44. The clamp cleaning assembly is provided on the clamp support 41 and is used to clean the lower surface of the cooling clamp 43.

[0036] Among them, combined Figure 6 The clamp cleaning assembly of this embodiment includes a second linear actuator 46 and a cleaning brush 47. Two second linear actuators 46 are provided and symmetrically arranged on the left and right sides of the two cooling clamps 43. The second linear actuators 46 are preferably lead screw and nut pairs. The cleaning brush 47 is driven by the two second linear actuators 46 and can be driven by the two second linear actuators 46 to move along the length direction of the cooling clamp 43. The cleaning brush 47 can be a sponge cleaning brush.

[0037] Before the cooling fixture 43 cools the sandwich panel 8, two half-covers 451 close and enclose the cooling fixture 43 with the fixture support 41. When the sandwich panel 8 moves into place, the protective cover drive cylinder 44 drives the two half-covers 451 to open, and the fixture drive cylinder 42 drives the cooling fixture 43 to extend out of the protective cover 45. After the sandwich panel 8 is cut, the fixture drive cylinder 42 drives the cooling fixture 43 to move away from the sandwich panel 8. The protective cover drive cylinder 44 drives the two half-covers 451 to close, so that the protective cover 45 and the fixture support 41 enclose the cooling fixture 43 again. Two second linear actuators 46 synchronously drive the cleaning brush 47, which moves against the lower surface of the cooling fixture 43 to clean away condensate and adhering dust. This prevents excessive dust accumulation on the lower surface of the cooling fixture 43 from affecting the cooling effect of the sandwich panel at the cut seam a. This also prevents accumulated dust from getting trapped between the sandwich panel 8 and the cooling fixture 43, which could cause dents or scratches on the surface of the sandwich panel 8. Furthermore, it prevents dust and condensation from falling back onto the sandwich panel 8, increasing the difficulty of cleaning.

[0038] See Figure 2 and Figure 3 In this embodiment, the clamp conveying line 5 is provided in two sets and is respectively set on the upper and lower sides of the sandwich panel conveying line 2. Each set is provided with two clamp conveying lines 5 and is installed on the support frame 1 opposite to each other. The two ends of each clamping cooling mechanism 4 are connected to the two opposite clamp conveying lines 5.

[0039] Combination Figure 7 , Figure 8 and Figure 9 In this embodiment, each clamp conveyor line 5 includes an annular chute 51 and a third linear drive. Combined with... Figure 3 and Figure 8 The annular slide groove 51 is installed on the support frame 1. Each annular slide groove 51 is a rectangular annular groove structure, specifically including an upper transverse slide groove 511, a right vertical slide groove 512, a lower transverse slide groove 513, and a left vertical slide groove 514 connected in sequence. Simultaneously, the annular slide groove 51 has an inner slide groove 515 and an outer slide groove 516 arranged from the inside to the outside. Figure 8 There are four third linear actuators, each corresponding to one of the four grooves of the annular slide 51, used to drive the clamping cooling mechanism 4 to slide within the corresponding groove. Specifically, in conjunction with... Figure 8The third linear actuators corresponding to the upper transverse slide groove 511 and the lower transverse slide groove 513 are both lead screw and nut pairs, including a second drive motor 52, a second lead screw shaft 56, a clamping block 53, an insert block 54, and a guide wheel 55. The second lead screw shaft 56 is arranged along the transverse slide groove and rotatably mounted in the inner slide groove 515 at the transverse slide groove. The motor shaft of the second drive motor 52 is connected to the second lead screw shaft 56 and can drive the second lead screw shaft 56 to rotate. The clamping block 53 has a threaded hole and is threadedly connected to the second lead screw shaft 56. The clamping block 53 is slidably connected to the inner slide groove 515 at the transverse slide groove, and the clamping block 53 has a clamping opening 531. Figure 5 , Figure 6 and Figure 7 The insert block 54 is connected to the clamp bracket 41 and can be inserted into the clamping opening 531 of the clamping block 53. Four guide wheels 55 are provided and evenly distributed around the insert block 54. The four guide wheels 55 are slidably connected to the outer sliding groove 516. Figure 3 and Figure 8 The third linear actuator corresponding to the right vertical slide 512 and the left vertical slide 514 is a drive cylinder. The drive cylinder corresponding to the left vertical slide 514 is the upper drive cylinder 57, which is located at the lower left corner of the annular slide 51. The drive cylinder corresponding to the right vertical slide 512 is the lower drive cylinder 58, which is located at the upper right corner of the annular slide 51.

[0040] After the sandwich panel 8 is cut, the second drive motor 52, which is located in the lower transverse slide groove 513, drives the clamping block 53 to move through the second lead screw shaft 56. The clamping block 53 drives the plug 54 and the clamping cooling mechanism 4 connected to it to move along the lower transverse slide groove 513 of the annular slide groove 51. When the clamping cooling mechanism 4 moves into place, the clamping block 53 and the plug 54 are exactly at the lower left corner of the annular slide groove 51 (the intersection of the left vertical slide groove 514 and the lower transverse slide groove 513). The telescopic rod of the upper drive cylinder 57 extends and squeezes the plug 54 so that the plug 54 is separated from the clamping block 53. At this time, the clamping cooling mechanism 4 is separated from the third linear actuator at the lower transverse slide groove 513. The upper drive cylinder 57 continues to drive the insert block 54 and moves the insert block 54 upward along the inner slide groove 515 in the left vertical slide groove 514; when the insert block 54 moves to the upper left corner of the annular slide groove 51 (the intersection of the left vertical slide groove 514 and the upper horizontal slide groove 511), the upper drive cylinder 57 drives the insert block 54 to insert into the clamping port 531 of the clamping block 53 at the upper horizontal slide groove 511, thereby realizing the connection between the clamping cooling mechanism 4 and the third linear actuator at the upper horizontal slide groove 511. The second drive motor 52 at the upper transverse slide 511 drives the clamping and cooling mechanism 4 to move along the upper transverse slide 511. When the clamping block 53 and the insert block 54 move to the upper right corner of the annular slide 51 (the intersection of the right vertical slide 512 and the upper transverse slide 511), the telescopic rod of the lower drive cylinder 58 extends and squeezes the insert block 54 to separate from the clamping block 53 again. At this time, the clamping and cooling mechanism 4 separates from the third linear actuator at the upper transverse slide 511. The lower drive cylinder 58 continues to drive the insert block 54 and moves it downward along the inner slide 515 in the right vertical slide 512 until it moves to the lower right corner of the annular slide 51. At this time, the clamping and cooling mechanism 4 returns to its initial position and can continue to clamp and cool the sandwich panel.

[0041] As can be seen, this embodiment uses four independently configured third linear actuators to drive the clamping cooling mechanism 4 to move within the annular slide 51. In the longer transverse slide, a lead screw and nut pair is used as the linear actuator, while in the vertical slide, a cylinder structure is used. This design ensures the support strength of the clamping cooling mechanism 4 provided by the clamping conveyor line 5, and also allows for smooth reversal and movement into the next slide with the cooperation of the extension rod of the drive cylinder, the clamping block 53, and the insertion block 54.

[0042] To avoid a decrease in the processing efficiency of the sandwich panel 8 due to the movement of the clamping and cooling mechanism 4 along with the sandwich panel 8, combined with... Figure 2 and Figure 3In this embodiment, the clamping and cooling mechanism 4 is provided in two sets. The two sets of clamping and cooling mechanisms 4 can be used alternately and cyclically. When one set of clamping and cooling mechanisms 4 moves with the cut sandwich panel 8, the other set of clamping and cooling mechanisms 4 can return to the cutting position of the sandwich panel 8 under the drive of the clamping conveyor line 5, so as to clamp and cool the next cut of the sandwich panel 8, thereby avoiding reducing the cutting speed of the sandwich panel 8 and extending the processing cycle.

[0043] See Figure 1 and Figure 2 The cutting mechanism 3 in this embodiment includes a first linear driver, a circular saw blade 34, and a circular saw blade drive assembly (not shown in the figure). The first linear driver is mounted on the support frame 1 and connected to the circular saw blade drive assembly, and can drive the circular saw blade drive assembly to move along the cutting direction of the sandwich plate 8. The circular saw blade drive assembly is drivenly connected to the circular saw blade 34 and can drive the circular saw blade 34 to rotate.

[0044] Among them, combined Figure 2 and Figure 3 The first linear actuator in this embodiment includes a first drive motor 31, a first lead screw 32, a first nut (not shown in the figure), and a first guide slider 33. The first drive motor 31 is mounted on the support frame 1. One end of the first lead screw 32 is fixedly connected to the motor shaft of the first drive motor 31, and the other end extends in the cutting direction of the sandwich plate 8 and is rotatably mounted on the support frame 1. The first nut is screwed onto the first lead screw 32, and the first guide slider 33 is sleeved on the first nut and slidably connected to the support frame 1.

[0045] When the first drive motor 31 drives the first lead screw shaft 32 to rotate, the first nut, under the limiting position of the first guide slider 33, drives the first guide slider 33 to move along the cutting direction of the sandwich panel. The first guide slider 33 drives the circular saw blade drive assembly and the circular saw blade 34 to move. The circular saw blade drive assembly drives the circular saw blade 34 to rotate, so that the circular saw blade 34 cuts the sandwich panel 8. After the circular saw blade 34 finishes cutting, the first drive motor 31 drives the first lead screw shaft 32 to rotate in the opposite direction, so that the circular saw blade 34 returns to its original position. In this embodiment, the circular saw blade drive assembly can be a DC brushless motor or a synchronous belt drive.

[0046] See Figure 2 and Figure 3The saw blade cooling mechanism 6 in this embodiment includes a cooling plate 61 and a drive cylinder (not shown in the figure). The drive cylinder is mounted on the support frame 1, and its extension rod is connected to the cooling plate 61. The cooling plate 61 is a circular cavity structure filled with coolant. After the circular saw blade 34 finishes cutting and returns to its initial position, the drive cylinder drives the cooling plate 61 to adhere to the surface of the circular saw blade 34, and coolant is introduced into the cooling plate 61 and circulated, thereby removing the heat from the circular saw blade 34, cooling the circular saw blade 34, and preventing excessive heat accumulation on the circular saw blade 34 from affecting the processing quality of the sandwich panel 8.

[0047] See Figure 2 , Figure 3 and Figure 10 The saw blade braking mechanism 7 in this embodiment includes a brake caliper 71 and a brake pad 72. The brake caliper 71 is mounted on the support frame 1, and the brake pad 72 is connected to the circular saw blade 34 and can rotate with the circular saw blade 34. When the circular saw blade 34 finishes cutting and returns to its initial position, the brake caliper 71 clamps the brake pad 72 to stop the circular saw blade 34. This avoids friction between the cooling disc 61 and the circular saw blade 34, which would affect the quality of the circular saw blade 34 and generate heat, thus affecting the cooling effect of the circular saw blade 34. It should be noted that the brake caliper 71 and brake pad 72 in this embodiment operate on the same principle as automobile brakes, and will not be described in detail here.

[0048] The following further explains the working process of the present invention to further demonstrate its working principle and advantages: When the sandwich panel conveyor line 2 transports the sandwich panel 8 to the cutting position, it stops transporting. The cover drive cylinder 44 drives the two half-covers 451 to open, and the two sets of clamp drive cylinders 42 respectively drive the two cooling clamps 43 to move down and fit against both sides of the sandwich panel cut a. Coolant is introduced into the cooling clamps 43 through the liquid inlet pipe, and the coolant flows out from the liquid outlet 432 of the cooling clamps 43. The first drive motor 31 of the cutting mechanism 3 drives the first lead screw shaft 32 to rotate. The first nut drives the first guide slider 33 to move along the cutting direction of the sandwich panel 8 under the limit of the first guide slider 33. The first guide slider 33 drives the circular saw blade drive assembly and the circular saw blade 34 to move. The circular saw blade drive assembly drives the circular saw blade 34 to rotate so that the circular saw blade 34 cuts the sandwich panel. During the cutting process, the heat of the sandwich panel 8 is transferred to the cooling fixture 43. The coolant in the cooling fixture 43 circulates continuously, which improves the heat exchange efficiency at the cut a of the sandwich panel 8 and ensures that the temperature at the cut a of the sandwich panel will not be too high.

[0049] After the sandwich panel 8 is cut, the clearance roller conveyor 21 transports the cut sandwich panel 8. The second drive motor 52, located in the lower transverse slide 513, drives the clamping block 53 to move via the second lead screw shaft 56. The clamping block 53 drives the connected insert block 54 and the clamping cooling mechanism 4 to move along the lower transverse slide 513 of the annular slide 51. At the same time, the rollers 211 move down sequentially along the conveying direction to avoid the clamping cooling mechanism 4, which moves synchronously with the sandwich panel 8.

[0050] When the clamping cooling mechanism 4 moves into position, the clamping block 53 and the insert block 54 are exactly at the lower left corner of the annular slide groove 51. The telescopic rod of the upper drive cylinder 57 extends and presses the insert block 54 to separate the insert block 54 from the clamping block 53. At this time, the clamping cooling mechanism 4 is separated from the third linear actuator at the lower transverse slide groove 513. The upper drive cylinder 57 continues to drive the insert block 54 and moves it upward along the inner slide groove 515 in the left vertical slide groove 514. When the insert block 54 moves to the upper left corner of the annular slide groove 51, the upper drive cylinder 57 drives the insert block 54 to insert into the clamping port 531 of the clamping block 53 at the upper transverse slide groove 511, thereby realizing the connection between the clamping cooling mechanism 4 and the third linear actuator at the upper transverse slide groove 511. The second drive motor 52 at the upper transverse slide 511 drives the clamping cooling mechanism 4 to move along the upper transverse slide 511. When the clamping block 53 and the insert block 54 move to the upper right corner of the annular slide 51, the telescopic rod of the lower drive cylinder 58 extends and squeezes the insert block 54 to separate it from the clamping block 53 again. At this time, the clamping cooling mechanism 4 separates from the third linear actuator at the upper transverse slide 511. The lower drive cylinder 58 continues to drive the insert block 54 and moves it downward along the inner slide 515 in the right vertical slide 512 until it moves to the lower right corner of the annular slide 51. At this time, the clamping cooling mechanism 4 returns to its initial position and can continue to clamp and cool the sandwich panel. During this process, the two sets of clamping drive cylinders 42 drive the two cooling clamps 43 to move upward and reset. The protective cover drive cylinder 44 drives the two half-covers 451 to close, so that the protective cover 45 and the clamping bracket 41 enclose the cooling clamps 43 again. Two second linear actuators 46 synchronously drive the cleaning brush 47, which moves in contact with the lower surface of the cooling clamp 43 to clean away condensation and adhering dust from the lower surface of the cooling clamp 43.

[0051] After the circular saw blade finishes cutting and returns to its initial position, the brake caliper 71 clamps the brake pad 72 to stop the circular saw blade 34. The drive cylinder drives the cooling plate 61 to adhere to the surface of the circular saw blade 34, and coolant is introduced into the cooling plate 61 and circulated, thereby removing the heat from the circular saw blade 34 and cooling it down.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions created by the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions created by the present invention without departing from the essence and scope of the technical solutions created by the present invention.
