Description

Technical Field

[0001] This utility model mainly relates to the technical field of thermoforming processes, specifically to a vacuum adsorption device for thermoforming processes. Background Technology

[0002] Thermoforming is a special plastic processing method that processes thermoplastic sheets into various products. For some thermoformed workpieces, vacuum adsorption devices are required for gripping.

[0003] Currently, vacuum adsorption devices used in thermoforming processes often connect the vacuum pump and the vacuum adsorption chamber via a gas delivery hose. In this method, the gas delivery hose moves with the vacuum adsorption chamber, which makes the hose prone to collision and entanglement with the vacuum adsorption chamber, thus affecting the use of the vacuum adsorption device. Utility Model Content

[0004] This utility model mainly provides a vacuum adsorption device for thermoforming processes to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A vacuum adsorption device for thermoforming process includes a base, a support frame connected to the upper surface of the base, a linear screw module connected to the top of the inside of the support frame, an adsorption mechanism connected to the actuating end of the linear screw module, and the adsorption mechanism connected to a negative pressure mechanism, which is connected to the upper surface of the support frame.

[0007] The negative pressure mechanism includes a vacuum pump connected to the upper surface of the support frame. The output end of the vacuum pump is connected to the input end of the negative pressure mechanism through a gas supply pipe, and the gas supply pipe is connected to the tensioning assembly.

[0008] Furthermore, the adsorption mechanism includes a slider connected to a linear screw module, a translation frame connected to the slider, and an electric push rod connected to the frame of the translation frame. The output end of the electric push rod is connected to a vacuum adsorption chamber, which is connected to a gas supply pipe and is located at the bottom end of the translation frame.

[0009] Furthermore, the tensioning assembly includes a rotating frame connected to the upper surface of the support frame, and a take-up and release wheel rotatably connected inside the rotating frame, with the air supply pipe wound around the wheel body of the take-up and release wheel.

[0010] Furthermore, the tensioning assembly also includes an elongated hole at the top of the support frame, the hole of which is used for the passage of the gas pipeline.

[0011] Furthermore, the two ends of the elongated hole are rotatably connected to rotating rods, and the two ends of the rotating rods are connected to first sprockets. The two first sprockets on the same side are connected by a first chain.

[0012] Furthermore, the bottom end of the first chain is connected to a connecting block, and the two connecting blocks are connected to the upper surface of the translation frame.

[0013] Furthermore, a second sprocket is connected to the outer surface of the rotating rod near one end of the take-up and release wheel. The second sprocket is connected to a third sprocket via a second chain. The third sprocket is coaxially arranged with the take-up and release wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention uses a translation frame to drive a connecting block, which in turn drives a first chain. Since the second sprocket is connected to a rotating rod, it rotates along with the rod. The second sprocket is connected to a third sprocket via a second chain, which in turn drives the third sprocket. Because the third sprocket is coaxial with the take-up and release wheel, it also drives the take-up and release wheel to rotate. In this way, the system automatically follows the take-up and release gas pipeline as the vacuum adsorption chamber moves, facilitating the movement and use of the gas pipeline.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] For an example, please refer to the appendix. Figure 1-3 A vacuum adsorption device for thermoforming process includes a base 1, a support frame 2 connected to the upper surface of the base 1, a linear screw module 3 connected to the top of the inside of the support frame 2, an adsorption mechanism 4 connected to the actuating end of the linear screw module 3, and the adsorption mechanism 4 connected to a negative pressure mechanism 5, which is connected to the upper surface of the support frame 2.

[0025] The negative pressure mechanism 5 includes a vacuum pump 51 connected to the upper surface of the support frame 2. The output end of the vacuum pump 51 is connected to the input end of the negative pressure mechanism 5 through a gas supply pipe 52. The gas supply pipe 52 is connected to the tensioning component 53.

[0026] For details, please refer to the appendix. Figure 1 and 2 The adsorption mechanism 4 includes a slider 41 connected to the linear screw module 3, a translation frame 42 connected to the slider 41, and an electric push rod 43 connected to the frame of the translation frame 42. The output end of the electric push rod 43 is connected to a vacuum adsorption chamber 44, which is connected to a gas delivery pipe 52. The vacuum adsorption chamber 44 is located at the bottom end of the translation frame 42.

[0027] The tensioning assembly 53 includes a rotating wheel frame 531 connected to the upper surface of the support frame 2, and a take-up and release wheel 532 rotatably connected inside the rotating wheel frame 531, wherein the gas supply pipe 52 is wound around the wheel body of the take-up and release wheel 532.

[0028] The tensioning assembly 53 also includes an elongated hole 539 located at the top of the support frame 2, the hole of which is used for the gas pipeline 52 to pass through.

[0029] It should be noted that in this embodiment, the linear screw module 3 drives the slider 41 connected to it to translate, the slider 41 drives the translation frame 42, and the translation frame 42 drives the vacuum adsorption chamber 44, so that the vacuum adsorption chamber 44 can be moved to the top of the workpiece.

[0030] Furthermore, the rotating frame 531 provides support for the take-up and release wheel 532, and by winding the gas pipeline 52 around the wheel body of the take-up and release wheel 532, the take-up and release of the gas pipeline 52 is facilitated.

[0031] Furthermore, the elongated orifice 539 is provided to allow for the movement of the gas pipeline 52.

[0032] For details, please refer to the appendix. Figure 2 and 3 The two ends of the elongated hole 539 are rotatably connected to a rotating rod 5391. The two ends of the rotating rod 5391 are connected to a first sprocket 533. The two first sprockets 533 on the same side are connected by a first chain 534.

[0033] The bottom end of the first chain 534 is connected to a connecting block 535, and the two connecting blocks 535 are connected to the upper surface of the translation frame 42;

[0034] A second sprocket 536 is connected to the outer surface of the rotating rod 5391 near the take-up and take-down wheel 532. The second sprocket 536 is connected to a third sprocket 538 via a second chain 537. The third sprocket 538 is coaxially arranged with the take-up and take-down wheel 532.

[0035] It should be noted that in this embodiment, the rotating rod 5391 provides support for the first sprocket 533, so that when the first chain 534 moves, it drives the first sprocket 533 connected to the first chain 534 to rotate, thereby driving the rotating rod 5391 to rotate.

[0036] Furthermore, the translation frame 42 drives the connecting block 535, which in turn drives the first chain 534 to operate.

[0037] Furthermore, since the second sprocket 536 is connected to the rotating rod 5391, the second sprocket 536 rotates along with the rotating rod 5391. Since the second sprocket 536 is connected to the third sprocket 538 through the second chain 537, the third sprocket 538 is driven to rotate. Thus, the second sprocket 536 drives the third sprocket 538. Since the third sprocket 538 is coaxially arranged with the take-up and release wheel 532, the take-up and release wheel 532 is driven to rotate. In this way, as the vacuum adsorption chamber 44 moves, the take-up and release gas pipeline 52 automatically follows, facilitating the movement and use of the gas pipeline 52.

[0038] The specific operation method of this utility model is as follows:

[0039] When moving a thermoformed workpiece using a vacuum adsorption device, the linear screw module 3 drives the connected slider 41 to move horizontally, the slider 41 drives the translation frame 42, and the translation frame 42 drives the vacuum adsorption chamber 44, so that the vacuum adsorption chamber 44 can move to the top of the workpiece and adsorb it.

[0040] The translation frame 42 drives the connecting block 535, which in turn drives the first chain 534. Since the second sprocket 536 is connected to the rotating rod 5391, the second sprocket 536 rotates with the rotating rod 5391. Since the second sprocket 536 is connected to the third sprocket 538 through the second chain 537, the third sprocket 538 rotates. The second sprocket 536 drives the third sprocket 538. Since the third sprocket 538 is coaxially set with the take-up and release wheel 532, the take-up and release wheel 532 rotates. In this way, as the vacuum adsorption chamber 44 moves, the take-up and release gas pipeline 52 automatically follows, facilitating the movement and use of the gas pipeline 52.

[0041] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
