Description

Technical Field

[0001] This utility model relates to the field of paper honeycomb sandwich technology, and in particular to a hot pressing mold for paper honeycomb sandwich structure. Background Technology

[0002] The paper honeycomb sandwich structure is a lightweight yet strong new material consisting of two layers of panels filled with a ring-shaped honeycomb core. This structure is typically made of aluminum, plastic, or paper, and can be square, louvered, or irregular in shape. The production of paper honeycomb sandwich structures usually involves using a thermoforming mold to heat and iron the structure.

[0003] After hot pressing the honeycomb sandwich structure with a thermoforming mold, the freshly processed honeycomb sandwich structure is still very hot. Manual unloading could result in burns. However, waiting for it to cool down before unloading would affect the feeding process of the thermoforming mold, thus impacting the overall efficiency of the mold. Therefore, how to automatically unload the processed honeycomb sandwich structure is a crucial problem that needs to be addressed in the design of the thermoforming mold for honeycomb sandwich structures. Utility Model Content

[0004] This invention addresses the problem of high temperatures in the processed honeycomb sandwich structure, which could lead to burns during manual unloading. It provides a hot-pressing mold for the honeycomb sandwich structure.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a hot pressing mold for a honeycomb sandwich structure of paper drum, including a support frame, and further comprising:

[0007] A pulling structure is provided on one side of the support frame;

[0008] The material receiving and heat dissipation structure is located on the other side of the support frame. The material receiving and heat dissipation structure receives the processed material while assisting in heat dissipation.

[0009] Preferably, a hydraulic cylinder is fixedly connected to the top inner wall of the support frame, the output bolt of the hydraulic cylinder is fixedly connected to the hot press upper mold, and a heating plate is fixedly connected to the bottom side wall of the hot press upper mold.

[0010] In this technical solution, the hydraulic cylinder descends, causing the upper hot pressing mold to descend, which in turn causes the second heating plate to descend, so that the second heating plate rests against the top of the placed paper honeycomb sandwich structure, and the second heating plate heats and irons the lower surface of the paper honeycomb sandwich structure.

[0011] Preferably, a support frame is fixedly connected to the bottom inner side wall of the support frame, one end of the hot pressing mold is rotatably connected to the side wall of the support frame, the other end of the hot pressing mold overlaps the top of the support frame, and a heating plate is fixedly connected to the top side wall of the hot pressing mold.

[0012] In this technical solution, the heating plate heats and irons the lower surface of a pair of paper honeycomb sandwich structures.

[0013] Preferably, the upper hot press mold faces the lower hot press mold.

[0014] Preferably, the pulling structure includes a first fixed rod, a second fixed rod, a first connecting rod, a second connecting rod, and a limiting rope. The first fixed rod is fixedly connected to the side wall of the upper hot press mold. The two ends of the first fixed rod are rotatably connected to one end of the first connecting rod. The other end of the first connecting rod is rotatably connected to one end of the second connecting rod. The other end of the second connecting rod is rotatably connected to the two ends of the second fixed rod. The second fixed rod is fixedly connected to the side wall of the lower hot press mold. One end of the limiting rope is fixedly connected to the side wall of the first connecting rod, and the other end of the limiting rope is fixedly connected to the side wall of the second connecting rod.

[0015] In this technical solution, the upper hot press mold drives the second connecting rod to rise, and the first connecting rod and the second connecting rod rotate and unfold. When the limiting rope is taut, the first connecting rod and the second connecting rod cannot continue to unfold. As the upper hot press mold continues to rise, the un-unfolded first connecting rod and the second connecting rod will pull one end of the lower hot press mold to rise. The lower hot press mold rotates upward and tilts after a certain distance.

[0016] Preferably, the material receiving and heat dissipation structure includes a material receiving frame, rollers, a limiting plate, and baffles. The material receiving frame is fixedly connected to the side wall of the support frame. Rollers are rotatably connected at equal intervals on the top side wall of the material receiving frame. Two baffles are fixedly connected to the top side wall of the material receiving frame. Limiting plates are fixedly connected to the ends of the material receiving frame and the baffles.

[0017] In this technical solution, the tilting of the hot-pressing mold causes the processed paper honeycomb sandwich structure to slide down onto the receiving rack under its own gravity, so that the paper honeycomb sandwich structure can be stored on the receiving rack.

[0018] Preferably, the top sidewall of the receiving rack is inclined, and the sidewall of the roller protrudes from the top sidewall of the receiving rack.

[0019] In this technical solution, the roller rotates during the sliding of the honeycomb sandwich structure, which can accelerate the sliding of the honeycomb sandwich structure.

[0020] Preferably, the highest point of the receiving rack is flush with the top side wall of the support frame.

[0021] Preferably, the material receiving and heat dissipation structure includes a ventilation duct, a dustproof net, and an exhaust fan. The ventilation duct is fixedly connected to the side wall of the baffle at equal intervals. An exhaust fan and two dustproof nets are fixedly connected to the inner side wall of the ventilation duct, and the two dustproof nets are located on both sides of the exhaust fan.

[0022] Preferably, the sidewall of the ventilation duct near the roller is flush with the sidewall of the baffle.

[0023] In this technical solution, the ventilation duct is prevented from protruding from the side wall of the baffle, thus avoiding affecting the downward movement of the processed honeycomb sandwich structure.

[0024] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0025] The positive and progressive effects of this utility model are as follows:

[0026] 1. The upper hot-pressing mold drives the second connecting rod to rise, causing the first and second connecting rods to rotate and unfold. When the limiting rope is taut, the first and second connecting rods cannot continue to unfold. As the upper hot-pressing mold continues to rise, the un-unfolded first and second connecting rods will pull one end of the lower hot-pressing mold to rise. The lower hot-pressing mold tilts, causing the processed paper honeycomb sandwich structure to slide onto the roller under its own weight. The roller rotates, accelerating the sliding of the paper honeycomb sandwich structure, which facilitates the automatic unloading of the processed paper honeycomb sandwich structure.

[0027] 2. After the paper-fed honeycomb sandwich structure is cut, it is placed on the receiving rack and stored. An exhaust fan blows air onto the finished paper-fed honeycomb sandwich structure to cool it down. During the cooling process, the paper-fed honeycomb sandwich structure can be loaded into the support frame. This facilitates better cooling of the unloaded paper-fed honeycomb sandwich structure during the loading process, preventing workers from getting burned and saving time. Attached Figure Description

[0034] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0035] like Figure 1-4 As shown, a hot-pressing mold for a honeycomb sandwich structure of paper drum includes a support frame 1, and further includes:

[0036] Pulling structure 4, which is disposed on one side of support frame 1;

[0037] Material receiving and heat dissipation structure 5 is located on the other side of support frame 1. The material receiving and heat dissipation structure 5 receives the processed material and assists in heat dissipation at the same time.

[0038] A hydraulic cylinder 7 is fixedly connected to the top inner wall of the support frame 1. The output bolt of the hydraulic cylinder 7 is fixedly connected to the hot press upper mold 2. A heating plate 6 is fixedly connected to the bottom side wall of the hot press upper mold 2.

[0039] The hydraulic cylinder 7 descends, causing the hot pressing upper mold 2 to descend. The hot pressing upper mold 2 then causes the heating plate 6 to descend, so that the heating plate 6 presses against the top of the placed paper honeycomb sandwich structure. The heating plate 6 heats and irons the lower surface of the paper honeycomb sandwich structure.

[0040] A support frame 9 is fixedly connected to the bottom inner side wall of the support frame 1. One end of the hot pressing mold 8 is rotatably connected to the side wall of the support frame 9. The other end of the hot pressing mold 8 overlaps the top of the support frame 9. A heating plate 3 is fixedly connected to the top side wall of the hot pressing mold 8.

[0041] Heating plate 3 heats and irons the lower surface of the honeycomb sandwich structure of the paper drum.

[0042] The upper hot press mold 2 is directly opposite the lower hot press mold 8.

[0043] The pulling structure 4 includes a first fixing rod 401, a second fixing rod 402, a first connecting rod 403, a second connecting rod 404, and a limiting rope 405. The first fixing rod 401 is fixedly connected to the side wall of the upper hot press mold 2. Both ends of the first fixing rod 401 are rotatably connected to one end of the first connecting rod 403. The other end of the first connecting rod 403 is rotatably connected to one end of the second connecting rod 404. The other end of the second connecting rod 404 is rotatably connected to both ends of the second fixing rod 402. The second fixing rod 402 is fixedly connected to the side wall of the lower hot press mold 8. One end of the limiting rope 405 is fixedly connected to the side wall of the first connecting rod 403, and the other end of the limiting rope 405 is fixedly connected to the side wall of the second connecting rod 404.

[0044] The upper hot press mold 2 drives the second connecting rod 404 to rise, and the first connecting rod 403 and the second connecting rod 404 rotate and unfold. When the limiting rope 405 is taut, the first connecting rod 403 and the second connecting rod 404 cannot continue to unfold. As the upper hot press mold 2 continues to rise, the un-unfolded first connecting rod 403 and the second connecting rod 404 will pull one end of the lower hot press mold 8 to rise. The lower hot press mold 8 rotates upward and tilts after a certain distance.

[0045] The material receiving and heat dissipation structure 5 includes a material receiving frame 501, rollers 502, a limiting plate 503, and baffles 504. The material receiving frame 501 is fixedly connected to the side wall of the support frame 1. Rollers 502 are rotatably connected at equal distances on the top side wall of the material receiving frame 501. Two baffles 504 are fixedly connected to the top side wall of the material receiving frame 501. The ends of the material receiving frame 501 and the baffles 504 are fixedly connected to the limiting plate 503.

[0046] The hot-pressing mold 8 tilts, causing the processed paper honeycomb sandwich structure to slide down onto the receiving rack 501 under its own gravity, so that the paper honeycomb sandwich structure can be stored on the receiving rack 501.

[0047] The top sidewall of the receiving rack 501 is inclined, and the sidewall of the roller 502 protrudes from the top sidewall of the receiving rack 501.

[0048] The roller 502 rotates during the sliding of the honeycomb sandwich structure, which can accelerate the sliding of the honeycomb sandwich structure.

[0049] The highest point of the receiving rack 501 is flush with the top side wall of the support frame 1.

[0050] The material receiving and heat dissipation structure 5 includes a ventilation duct 511, a dustproof net 512, and an exhaust fan 513. The ventilation duct 511 is fixedly connected to the side wall of the baffle 504 at equal distances. The exhaust fan 513 and two dustproof nets 512 are fixedly connected to the inner side wall of the ventilation duct 511. The two dustproof nets 512 are located on both sides of the exhaust fan 513.

[0051] The side wall of the ventilation duct 511 near the roller 502 is flush with the side wall of the baffle 504.

[0052] To prevent the ventilation duct 511 from protruding from the side wall of the baffle 504, which would affect the downward movement of the processed honeycomb sandwich structure of the paper drum.

[0053] In use, all electrical components mentioned in this application are externally connected to a power supply and control switch. The material coated with glue is placed on the heating plate 3. The hydraulic cylinder 7 descends, causing the upper hot pressing mold 2 to descend. The upper hot pressing mold 2 causes the heating plate 6 to descend, so that the heating plate 6 rests against the top of the placed paper honeycomb sandwich structure. The heating plate 3 heats and irons the lower surface of the paper honeycomb sandwich structure, and the heating plate 6 heats and irons the lower surface of the paper honeycomb sandwich structure. The fixing rod 401 descends in response to the descent of the upper hot pressing mold 2. The descent of the fixing rod 401 causes the connecting rod 404 to descend and rotate. The connecting rod 404 causes the connecting rod 403 to rotate. The connecting rod 403 and the connecting rod 404 are folded together and will not affect the hot pressing and ironing of the upper hot pressing mold 2 and the lower hot pressing mold 8.

[0054] After the honeycomb sandwich structure is hot-pressed, the hydraulic cylinder 7 drives the upper hot-pressing mold 2 to rise. The upper hot-pressing mold 2 drives the connecting rod 404 to rise. The connecting rod 403 and the connecting rod 404 rotate and unfold. When the limiting rope 405 is taut, the connecting rod 403 and the connecting rod 404 cannot continue to unfold. As the upper hot-pressing mold 2 continues to rise, the connecting rod 403 and the connecting rod 404 that cannot unfold will pull one end of the lower hot-pressing mold 8 to rise. The lower hot-pressing mold 8 rotates upward and tilts after a certain distance. The tilting causes the processed honeycomb sandwich structure to slide down onto the roller 502 under its own weight. The roller 502 rotates, accelerating the sliding of the honeycomb sandwich structure, so that the honeycomb sandwich structure falls onto the receiving rack 501 for storage, which facilitates the automatic unloading of the processed honeycomb sandwich structure.

[0055] The exhaust fan 513 draws air and blows it onto the processed paper honeycomb sandwich structure to cool it down. During the cooling process, the paper honeycomb sandwich structure can be loaded into the support frame 1, which facilitates better cooling of the unloading paper honeycomb sandwich structure during the loading process, avoiding burns to workers and saving time.

[0056] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
