Description

Technical Field

[0001] This invention relates to the field of aluminum composite panel production technology, specifically to a hot-press forming device for preventing aluminum composite panels from sticking. Background Technology

[0002] Aluminum-plastic composite panels (APCs) are three-layer composite panels with a plastic core and aluminum on both sides, covered with a decorative and protective coating or film. Existing APC thermoforming equipment requires placing the core layer between the aluminum sheets before thermoforming. After forming, the APC is cut for use. However, due to misalignment between the core layer and the aluminum sheets, the core layer is often exposed around the edges of the aluminum sheet. This causes the exposed plastic core layer to extend outwards under pressure during thermoforming, sticking to the external equipment and making the formed APC difficult to remove. Therefore, a device is urgently needed to solve these problems. Summary of the Invention

The first hydraulic cylinders are symmetrically arranged on the support plate, and the bottom end of the first hydraulic cylinder is rotatably mounted inside the upper end of the support plate. The upper end of the first hydraulic cylinder is rotatably connected to the outer end of the guide adjustment plate. The fixed frame is fixedly connected to the inner end of the guide conveyor frame. The second hydraulic cylinders are uniformly fixedly mounted on the fixed frame. The extrusion pusher plate is fixedly connected to the front end of the second hydraulic cylinder.

[0005] Preferably, the feeding alignment device includes a first centering feeding device, a second centering feeding device, a third centering feeding device, and a guiding support frame. The first centering feeding device, the second centering feeding device, and the third centering feeding device are all slidably engaged inside the guiding support frame, and the first centering feeding device, the second centering feeding device, and the third centering feeding device have the same structure.

[0006] Preferably, the first, second, and third centering feeding devices each include a control unit, a fixed frame rod, a connecting horizontal plate, a feeding plate, and a mounting groove. The control unit is distributed on both sides of the feeding plate, the mounting groove is formed inside the feeding plate, the connecting horizontal plate is fixedly connected to both ends of the feeding plate, and the fixed frame rod is fixedly connected to the upper part of both sides of the feeding plate.

[0007] Preferably, the control unit includes a partition limiting plate, a sliding block, a limiting placement groove, a first adjusting toothed plate, an adjusting toothed column, a motor, a synchronous rotating belt, a rotating wheel, and a second adjusting toothed plate. The second adjusting toothed plate is disposed above the first adjusting toothed plate. There are three adjusting toothed columns, which are distributed between the first adjusting toothed plate and the second adjusting toothed plate. The adjusting toothed columns are meshed with the second adjusting toothed plate and the first adjusting toothed plate. The rotating wheel is fixedly connected to the middle of the outer end of the adjusting toothed column. The synchronous rotating belt is rotatably engaged between the rotating wheels. The motor is fixedly mounted on the fixed frame rod, and the front end of the motor is fixedly connected to the middle of the outer end of the rotating wheel.

[0008] Preferably, the guiding part includes a feeding frame, a fixed upright frame, a fixed connecting frame, a third hydraulic cylinder, and a partition block. The partition block is uniformly and fixedly installed on the upper outer side of the feeding frame. The feeding frame is fixedly installed inside the fixed upright frame through the partition block. The fixed upright frame is fixedly installed inside the fixed connecting frame. The third hydraulic cylinder is uniformly and symmetrically fixedly installed on the fixed connecting frame, and the third hydraulic cylinder is located below the fixed upright frame.

[0009] Preferably, rotating guide rollers are rotatably installed on both sides of the bottom bend of the feeding frame.

[0010] Preferably, the end of the fixed connection frame is fixedly connected to the outer end of the material guide support frame, the front end of the third hydraulic cylinder is fixedly connected to the connecting horizontal plate, and the material replenishment frame is arranged in a trapezoidal shape.

[0011] Preferably, the upper inner end of the guide conveyor frame is fixedly connected to the bottom of the electric heating plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] I. This invention utilizes the guide parts at both ends and the side of the feeding alignment device to automatically and neatly feed aluminum plates and plastic cores into the third, second, and first central feeding devices. This allows the third, second, and first central feeding devices to automatically and neatly transport and add the hot-pressed aluminum plates and plastic cores to the center of the guide support frame. The aluminum plates are distributed on both sides of the plastic core. Because the plastic core can be neatly fed to the middle of the two aluminum plates, and the feeding plate in the first central feeding device is slightly smaller than the feeding plates in the second and third central feeding devices, the added plastic core is slightly smaller than the aluminum plate. This prevents the plastic core from overflowing between the aluminum plates and sticking to the outside during hot pressing.

[0014] Second, the present invention can control the feeding plate to slide out from the inside of the guide support frame to the bottom of the replenishment frame through the third hydraulic cylinder. The replenishment frame is trapezoidal in shape, and rotating guide rollers are rotatably arranged on both sides inside the replenishment frame, so that the added aluminum plate or plastic core can fall neatly in the middle of the feeding plate after passing through the replenishment frame, and the four corners are located on the limiting placement groove and are stably supported.

[0015] Third, the present invention utilizes a control unit to ensure that the aluminum plate and plastic core, which are conveyed to the middle of the material guide support frame and are neatly aligned, fall directly above the electric heating plate from the middle of the material guide support frame. During the falling process, the aluminum plate is neatly distributed on both sides of the plastic core by the limiting and blocking of the guide adjustment plate. Since the plastic core is slightly smaller than the aluminum plate, the plastic core will not be squeezed out between the aluminum plates and come into contact with and stick to the external device during the hot pressing process.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This invention provides an embodiment of a thermoforming device for preventing sticking of aluminum composite panels, comprising a supporting column 2, a fixed supporting base 3, a forming section 4, a feeding and alignment device 5, and a guiding section 6. The fixed supporting base 3 is fixedly connected to the bottom outer end of the forming section 4, the feeding and alignment device 5 is fixedly connected to the upper end of the forming section 4, the supporting column 2 is fixedly connected to the outer end of the fixed supporting base 3, and three guiding sections 6 are provided, distributed outside the feeding and alignment device 5. The bottom end of the guiding section 6 is fixedly connected to the upper end of the supporting column 2. The forming section 4... The system includes a guide conveyor frame 7, a first hydraulic cylinder 8, a guide adjusting plate 9, a support plate 10, an electric heating plate 11, a fixed frame 12, a second hydraulic cylinder 13, and a pressing and pushing plate 14. The electric heating plate 11 is fixedly connected to the bottom inner end of the guide conveyor frame 7. The support plate 10 is fixedly connected to both sides of the inner end of the guide conveyor frame 7. The guide adjusting plate 9 is rotatably mounted on the upper inner end of the guide conveyor frame 7. The first hydraulic cylinders 8 are symmetrically arranged on the support plate 10, and the bottom end of the first hydraulic cylinder 8 is rotatably mounted inside the upper end of the support plate 10. The upper end of the first hydraulic cylinder 8 rotates... Connected to the outer end of the guide adjustment plate 9, the fixed frame 12 is fixedly connected to the inner end of the guide conveying frame 7. The second hydraulic cylinder 13 is evenly fixedly installed on the fixed frame 12. The extrusion push plate 14 is fixedly connected to the front end of the second hydraulic cylinder 13. Through the guide parts 6 provided at both ends and the guide parts 6 provided at the side ends of the feeding alignment device 5, aluminum plates and plastic cores can be automatically and neatly fed into the third centering feeding device 17, the second centering feeding device 16, and the first centering feeding device 15. Thus, the third centering feeding device 17 and the second centering feeding device 15 are used to automatically and neatly feed aluminum plates and plastic cores into the interior of the third centering feeding device 17, the second centering feeding device 16, and the first centering feeding device 15. The material feeding device 16 and the first central feeding device 15 can neatly and automatically convey and add the hot-pressed material aluminum plate and plastic core to the middle of the guide support frame 18. The aluminum plate is distributed on both sides of the plastic core. Since the plastic core can be neatly conveyed to the middle position of the two aluminum plates, and the feeding plate 22 in the first central feeding device 15 is slightly smaller than the feeding plate 22 in the second central feeding device 16 and the third central feeding device 17, the added plastic core is slightly smaller than the aluminum plate, so that the plastic core will not overflow from between the aluminum plates and stick to the outside during hot pressing.

[0028] Please see Figure 5 The feeding alignment device 5 includes a first centering feeding device 15, a second centering feeding device 16, a third centering feeding device 17, and a guiding support frame 18. The first centering feeding device 15, the second centering feeding device 16, and the third centering feeding device 17 are all slidably engaged inside the guiding support frame 18. The first centering feeding device 15, the second centering feeding device 16, and the third centering feeding device 17 have the same structure.

[0029] Please see Figure 6The first, second, and third centered feeding devices 15, 16, and 17 each include a control unit 19, a fixed frame rod 20, a connecting horizontal plate 21, a feeding plate 22, and a mounting groove 23. The control unit 19 is distributed on both sides of the feeding plate 22, the mounting groove 23 is opened inside the feeding plate 22, the connecting horizontal plate 21 is fixedly connected to both ends of the feeding plate 22, and the fixed frame rod 20 is fixedly connected to the upper part of both sides of the feeding plate 22. The control unit 19 allows the aluminum plate and plastic core, which are neatly aligned in the middle of the guide support frame 18, to fall from the middle of the guide support frame 18 directly above the electric heating plate 11. During the falling process, the aluminum plate is neatly distributed on both sides of the plastic core by the limiting and blocking of the guide adjustment plate 9. Since the plastic core is slightly smaller than the aluminum plate, the plastic core will not be squeezed out between the aluminum plates and come into contact with and stick to the external device during the hot pressing process.

[0030] Please see Figure 7 The control unit 19 includes a partition limit plate 24, a sliding block 25, a limit placement groove 26, a first adjusting tooth plate 27, an adjusting tooth column 28, a motor 29, a synchronous rotating belt 30, a rotating wheel 31, and a second adjusting tooth plate 32. The second adjusting tooth plate 32 is located above the first adjusting tooth plate 27. There are three adjusting tooth columns 28, which are distributed between the first adjusting tooth plate 27 and the second adjusting tooth plate 32. The adjusting tooth columns 28 are meshed with the second adjusting tooth plate 32 and the first adjusting tooth plate 27. The rotating wheel 31 is fixedly connected to the middle of the outer end of the adjusting tooth column 28. The synchronous rotating belt 30 is rotatably engaged between the rotating wheels 31. The motor 29 is fixedly installed on the fixed frame rod 20. The front end of the motor 29 is fixedly connected to the middle of the outer end of the middle rotating wheel 31.

[0031] Please see Figure 8 and Figure 9 The guiding unit 6 includes a feeding frame 33, a fixed upright frame 34, a fixed connecting frame 35, a third hydraulic cylinder 36, and a baffle block 37. The baffle block 37 is evenly and fixedly installed on the upper outer side of the feeding frame 33. The feeding frame 33 is fixedly installed inside the fixed upright frame 34 through the baffle block 37. The fixed upright frame 34 is fixedly installed inside the fixed connecting frame 35. The third hydraulic cylinder 36 is evenly and symmetrically fixedly installed on the fixed connecting frame 35, and the third hydraulic cylinder 36 is located below the fixed upright frame 34. The third hydraulic cylinder 36 can control the feeding plate 22 to slide out from inside the guiding support frame 18 to below the feeding frame 33. The feeding frame 33 is trapezoidal in shape, and rotating guiding rollers 38 are rotatably installed on both sides inside the feeding frame 33, so that the added aluminum plate or plastic core can fall neatly and centrally into the middle of the feeding plate 22 after passing through the feeding frame 33, and the four corners are stably supported and lifted by the limiting placement groove 26.

[0032] Please see Figure 9Rotating guide rollers 38 are installed inside the two sides of the bottom bend of the feeding frame 33. By rotating the guide rollers 38, the aluminum plate or plastic core that slides down along the feeding frame 33 can slide smoothly.

[0033] The end of the fixed connection frame 35 is fixedly connected to the outer end of the guide support frame 18, the front end of the third hydraulic cylinder 36 is fixedly connected to the connecting horizontal plate 21, and the feeding frame 33 is set in a trapezoidal shape, which plays the role of feeding material in the center.

[0034] The upper inner end of the guide conveyor frame 7 is fixedly connected to the bottom of the electric heating plate 11. By activating the electric heating plate 11, the aluminum plate and plastic core at the upper end of the electric heating plate 11 can be heated, thus enabling the hot pressing to be completed smoothly.

[0035] Working principle: The third hydraulic cylinder 36 in the three guiding parts 6 is activated synchronously. The third hydraulic cylinder 36 pulls the connecting horizontal plate 21, causing the feeding plates 22 in the first central feeding device 15, the second central feeding device 16, and the third central feeding device 17 to slide outward along the guiding support frame 18 to directly below the replenishing frame 33. At this time, aluminum plates are added into the replenishing frames 33 distributed at both ends of the feeding alignment device 5, and plastic cores are added into the replenishing frames 33 outside the feeding alignment device 5. Since the replenishing frames 33 are trapezoidal, the aluminum plates and plastic cores that slide down from the replenishing frames 33 can fall centrally and be discharged in the middle of the corresponding feeding plate 22. The four corners of the falling aluminum plates and plastic cores are limited and placed. The groove 26 supports and lifts the filter element, and then the third hydraulic cylinder 36 is activated simultaneously to make the three feeding plates 22 slide and reset. At this time, the plastic filter element is located between the two aluminum plates. The feeding plate 22 in the first central feeding device 15 is slightly smaller than the feeding plate 22 in the second central feeding device 16 and the third central feeding device 17, so that the added plastic core is slightly smaller than the aluminum plate. Then, the motor 29 in the second central feeding device 16 is activated first. The motor 29 drives the central adjusting gear 28 and the rotating wheel 31 to rotate. The rotating adjusting gear 28 and the rotating wheel 31 can rotate synchronously through the synchronous rotating belt 30. The rotating first adjusting gear 27 can control the first adjusting gear 27 and the second adjusting gear 32 to slide along both sides of the mounting groove 23, so that the sliding... Block 25 slides along the mounting groove 23 towards both ends of the feeding plate 22. At this time, the portion of the sliding block 25 with the limiting placement groove 26 retracts into the mounting groove 23. The end frame of the aluminum plate is not supported by the limiting placement groove 26, causing the aluminum plate to fall from the center of the guide support frame 18. During the fall, the two sides of the aluminum plate contact the inner walls of the symmetrically distributed guide adjustment plates 9. The limiting effect of the guide adjustment plates 9 ensures the aluminum plate lands centered on the top of the electric heating plate 11. By controlling the plastic core and another aluminum plate to fall, and activating the first hydraulic cylinder 8 to control the rotation of the guide adjustment plates 9 when the plastic core falls, the guiding and limiting angles of the guide adjustment plates 9 are adjusted and controlled, allowing plastic plates with a length and width slightly smaller than the aluminum plate to accurately fall onto the aluminum plate. In the middle, the plastic core is precisely and neatly positioned between the two aluminum plates. At this point, the aluminum plates and plastic core are heated by the electric heating plate 11. After 30 seconds, the external extrusion device presses down onto the aluminum plates through the middle of the guide support frame 18. The molten plastic core then adheres to the aluminum plates, completing the hot pressing process. Because the plastic core and aluminum plates are neatly arranged, and the plastic core is slightly smaller than the aluminum plates, the plastic core will not be squeezed out between the aluminum plates and come into contact with the external device during the hot pressing process. Furthermore, during the hot pressing process, the first hydraulic cylinder 8 controls the guide adjustment plate 9 to rotate outwards, ensuring that even if molten plastic core material is squeezed out from both sides of the aluminum plates during the hot pressing process, it will not come into contact with the inside of the guide adjustment plate 9, facilitating the unloading of the aluminum-plastic composite sheet.After hot pressing, the aluminum-plastic composite sheet is pushed by the second hydraulic cylinder 13, along with the extrusion pusher 14, onto the guide conveyor frame 7 and discharged. During operation, this device automatically feeds plastic cores, slightly smaller in width and length than the aluminum sheet, ensuring the cores are precisely positioned in the center of the aluminum sheet. This prevents the plastic cores from overflowing and sticking during hot pressing due to pressure from the sides of the sheet. Furthermore, the device automatically and precisely completes feeding and discharging during hot pressing, improving efficiency.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
