Description

Technical Field

[0001] This utility model relates to the field of foam clamping technology, and in particular to a clamping device for processing foam plastic products. Background Technology

[0002] In modern industrial production, foamed plastic products are widely used in many fields such as packaging, construction, home furnishing, and aerospace due to their excellent properties such as light weight, heat insulation, sound insulation, and shock absorption. For example, in the packaging of electronic products, foamed plastics can effectively buffer vibrations and impacts during transportation, protecting the products from damage. In the construction industry, foamed plastics can be used as thermal insulation materials to improve the energy efficiency of buildings. As the application scope of foamed plastic products continues to expand, the requirements for their processing precision and quality are also increasing. In the processing of foamed plastics, such as cutting, carving, and molding, it is necessary to clamp the foamed plastic products stably and reliably to ensure the smooth progress of processing operations and the realization of processing precision.

[0003] Existing clamping devices for processing foam plastic boards have the disadvantage of poor clamping effect, which makes it easy for the foam plastic boards to deviate during processing, resulting in the inability to effectively process the foam plastic boards, the inability to guarantee the quality of the foam plastic boards, inconvenience in use, and reduced efficiency of the clamping device and the effect of the foam plastic boards. Therefore, a clamping device for processing foam plastic boards is proposed to solve the above-mentioned problems.

[0004] An existing patent (publication number: CN210968600U) discloses a clamping device for processing foam plastic boards, including a clamping box. A motor box is fixedly connected to the right side of the clamping box, and a drive motor is fixedly connected to the right side wall of the motor box. This clamping device for processing foam plastic boards uses the drive motor to rotate a drive rod. During the rotation of the drive rod, a threaded rod rotates, causing a threaded block and a movable block to move relative to or away from each other. This, in turn, causes a moving plate and a movable plate to move relative to each other, sequentially moving an electric push rod, a fixed clamping plate, and a rubber pad left and right. When the rubber pad moves above the foam plastic board, the electric push rod sequentially moves the fixed clamping plate and the rubber pad up and down. During the up-and-down movement of the rubber pad, the foam plastic board is clamped, achieving the purpose of clamping the foam plastic board and effectively processing it.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, most existing clamping devices are mechanical clamping structures, which can easily lead to product damage due to excessive clamping or product displacement during processing due to excessive clamping. Furthermore, during the clamping process, there is a lack of a structure to remove static electricity from the foam plastic products, causing the surface of the foam plastic products to attract a large amount of dust and debris due to static electricity, thereby reducing the clamping effect of the clamping device on the foam plastic products.

[0006] Therefore, a clamping device for processing foam plastic products is proposed. Utility Model Content

[0018] 1.

This allows the ion air bars to work stably, improves the static elimination effect, and extends the service life of the equipment. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A clamping device for processing foam plastic products includes a workbench 1, a clamping mechanism 2 fixedly connected to the top of the workbench 1, and an antistatic mechanism 3 fixedly connected to the top of the clamping mechanism 2.

[0030] The clamping mechanism 2 includes a lower electromagnet plate 21, a connecting block 22, a limiting post 23, two upper electromagnet plates 24, a limiting shell 25, a slider 26, a lead screw 27, a limiting rod 28, and a servo motor 29. The lower electromagnet plate 21 is fixedly connected to the top of the worktable 1, the connecting block 22 is fixedly connected to both sides of the lower electromagnet plate 21, the limiting post 23 is fixedly connected to the top of the connecting block 22, the upper electromagnet plates 24 are slidably connected to the surface of the limiting post 23, the limiting shell 25 is fixedly connected to both sides of the top of the worktable 1, the lead screw 27 is rotatably connected to the inside of the left limiting shell 25, the limiting rod 28 is fixedly connected to the inside of the right limiting shell 25, and the servo motor 29 is fixedly connected to the bottom of the worktable 1. The output end of the top of the servo motor 29 passes through the worktable 1 and is fixedly connected to the bottom of the lead screw 27.

[0031] In this embodiment: the workbench 1 supports and limits the clamping mechanism 2 and the static elimination mechanism 3. The lower electromagnet plate 21 generates electromagnetic force when energized, which cooperates with the upper electromagnet plate 24 to adsorb and clamp the foam plastic product. Compared with the traditional mechanical clamping method, electromagnetic clamping is more uniform, reduces damage to the surface of the foam plastic, and provides a stable clamping force to prevent product displacement during processing. The connecting block 22 connects the lower electromagnet plate 21 and the limiting post 23, ensuring the accurate installation position of the limiting post 23, so that the upper electromagnet plate 24 can... The upper electromagnet plate 24 slides stably on the limiting post 23 and evenly transmits the force of the lower electromagnet plate 21, enhancing the overall structural strength of the clamping mechanism 2. The limiting post 23 provides guidance and limitation for the sliding of the upper electromagnet plate 24, ensuring that the upper electromagnet plate 24 maintains linear motion when moving horizontally, thus improving the clamping accuracy and stability. The upper electromagnet plate 24 and the lower electromagnet plate 21 cooperate to generate electromagnetic force to clamp the foam plastic product. The two upper electromagnet plates 24 can slide on the limiting post 23. By adjusting the height of the upper electromagnet plates 24, it can accommodate foams of different thicknesses. The use of plastic components improves the versatility of the device. Simultaneously, the rear sides of the two upper electromagnet plates 24 are connected by a connecting rod, allowing them to move synchronously up and down via the rotation of the lead screw 27. The limiting housing 25 provides mounting support for the lead screw 27 and the limiting rod 28. The left slider 26 is threadedly connected to the lead screw 27, and the right slider 26 is slidably connected to the limiting rod 28, converting the rotational motion of the lead screw 27 into the linear motion of the upper electromagnet plate 24, thus achieving height adjustment of the upper electromagnet plate 24. The lead screw 27 rotates under the drive of the servo motor 29, moving via the threaded connection with the left slider 26... In coordination, the upper electromagnet plate 24 on the left moves, and works in conjunction with the limiting rod 28 on the right and the slider 26 on the right to enable the two upper electromagnet plates 24 to move up or down synchronously. The limiting rod 28 is slidably connected to the slider 26 on the right, which guides and limits the movement of the upper electromagnet plate 24 on the right, ensuring that the upper electromagnet plate 24 on the right remains parallel to the upper electromagnet plate 24 on the left during the movement. The servo motor 29 can drive the lead screw 27 to rotate, thereby enabling the upper electromagnet plates 24 to move up and down, meeting the clamping requirements of foam plastic products of different thicknesses.

[0032] Specifically, such as Figure 2 , Figure 3 As shown, the left slider 26 is fixedly connected to the left side of the left upper electromagnet plate 24, and the right slider 26 is fixedly connected to the right side of the right upper electromagnet plate 24. The left slider 26 is threadedly connected to the surface of the lead screw 27, and the right slider 26 is slidably connected to the surface of the limit rod 28.

[0033] Specifically, such as Figure 4 , Figure 5As shown, the static elimination mechanism 3 includes two ion air bars 31, a high-voltage generator 32, a diverter pipe 33, a connecting hose 34, a support base 35, an oil-water separator 36, an air pipe 37, and an air compressor 38. The left side of the ion air bar 31 is fixedly connected to the top of the upper electromagnet plate 24 on the left side.

[0034] Specifically, such as Figure 4 , Figure 5 As shown, the right side of the ion bar 31 is fixedly connected to the top of the upper electromagnet plate 24 on the right side, the high voltage generator 32 is fixedly connected to the right side of the top of the support base 35, the connecting wire of the ion bar 31 passes through the workbench 1 and is fixedly connected to the output end of the top of the high voltage generator 32, the shunt pipe 33 is fixedly connected to the left side of the ion bar 31, and the connecting hose 34 is fixedly connected to the bottom of the shunt pipe 33.

[0035] In this embodiment: by setting the ion bar 31 to generate ions with opposite charges through the high voltage provided by the high voltage generator 32, these ions are blown onto the surface of the foam plastic product to neutralize the static electricity on the surface, thereby eliminating electrostatic adsorption and ensuring the cleanliness and quality of the product. The high voltage generator 32 provides high voltage to the ion bar 31 to enable it to generate ions. The distributor 33 evenly distributes the compressed air generated by the air compressor 38 into the ion bar 31, ensuring that the ion bar 31 can obtain a stable airflow, so that the ions can be effectively blown onto the surface of the foam plastic product, improving the static elimination effect. The connecting hose 34 connects to the diverter 33 and the oil-water separator 36, enabling the transmission of compressed air. The support base 35 supports and limits the oil-water separator 36, the air compressor 38, and the high-pressure generator 32. The oil-water separator 36 purifies the compressed air generated by the air compressor 38, removing impurities such as oil and water to ensure that the air entering the ion bar 31 is clean. The air pipe 37 connects the oil-water separator 36 and the air compressor 38 to transmit compressed air. The air compressor 38 generates compressed air to power the ion bar 31, enabling ions to be blown onto the surface of the foam plastic product.

[0036] Specifically, such as Figure 4 , Figure 5 As shown, the support base 35 is fixedly connected to the bottom of the workbench 1, the oil-water separator 36 is fixedly connected to the top left side of the support base 35, the bottom of the connecting hose 34 passes through the workbench 1 and is fixedly connected to the left side of the oil-water separator 36, the air pipe 37 is fixedly connected to the right side of the oil-water separator 36, the air compressor 38 is fixedly connected to the top right side of the support base 35, and the right side of the air pipe 37 is fixedly connected to the output end on the left side of the air compressor 38.

[0037] Specifically, such as Figure 5 As shown, a limiting ring 4 is fixedly connected to the top of the limiting post 23, and the surface of the limiting ring 4 is coated with an anti-corrosion coating.

[0038] In this embodiment: by setting a limiting ring 4, the upper electromagnet plate 24 can be prevented from accidentally detaching during the sliding process along the limiting post 23. By setting an anti-corrosion coating, it can effectively resist corrosive substances that may exist in the working environment and extend the service life of the limiting ring 4.

[0039] Specifically, such as Figure 1 As shown, rubber pads 5 are fixedly connected to the top of the lower electromagnet plate 21 and the bottom of the upper electromagnet plate 24. The surface of the rubber pads 5 is engraved with anti-slip texture.

[0040] Specifically, such as Figure 6 As shown, a sealing ring 6 is fixedly connected at the connection between the connecting hose 34 and the oil-water separator 36, and the surface of the sealing ring 6 is coated with an anti-corrosion coating.

[0041] In this embodiment: by setting the rubber pad 5, it can closely adhere to the surface of the foam plastic product when in contact, increasing the contact area and thus increasing the friction. By setting the anti-slip texture, the smoothness between the contact surfaces is further disrupted, significantly improving the friction and effectively preventing the foam plastic product from sliding during clamping. By setting the sealing ring 6, a good sealing effect is achieved, which can effectively prevent compressed air from leaking from the connection during transmission. By setting the anti-corrosion coating, the sealing ring 6 can be protected from the erosion of oil, water and other corrosive substances that may be carried in the compressed air.

[0042] Working principle: First, the user installs the workbench 1 in a suitable working position. Then, the user places the foam plastic product to be processed on top of the lower electromagnet plate 21. Next, the user powers on and starts the static elimination mechanism 3. At this time, the air compressor 38 starts to operate, generating compressed air. This compressed air is transported to the oil-water separator 36 through the air pipe 37. The oil-water separator 36 purifies the compressed air, removing impurities such as oil and water. Then, the purified compressed air is introduced into the connecting hose 34, which then transmits the compressed air to the distribution pipe 3. 3. The diverter pipe 33 guides compressed air to flow to the two ionizer bars 31. Under the high voltage provided by the high voltage generator 32, the ionizer bars 31 generate a large number of ions. At the same time, with the help of the compressed air, these ions are blown downwards to the surface of the foam plastic product, quickly neutralizing the static charge on its surface, thereby eliminating static electricity from the foam plastic product. Then, the user turns on the power and starts the servo motor 29. The drive screw 27 of the servo motor 29 begins to rotate. As the screw 27 rotates, the left slider 26, which is threaded to it, moves up and down on the screw 27. Because the left slider 26 is fixedly connected to the left upper electromagnet plate 24, the movement of the left slider 26 will synchronously drive the left upper electromagnet plate 24 to move up and down. Since the left upper electromagnet plate 24 and the right upper electromagnet plate 24 are connected at the rear by a connecting rod, the right upper electromagnet plate 24 will move synchronously with the left upper electromagnet plate 24. When the two upper electromagnet plates 24 move downwards to make close contact with the top of the foam plastic product, the user turns off the servo motor 29, stopping the movement of the upper electromagnet plates 24. Then, the user moves the lower electromagnet plate 21 and the two upper electromagnet plates... When plate 24 is energized, the two upper electromagnet plates 24 and the lower electromagnet plate 21 generate a strong magnetic force, which stably and firmly clamps the foam plastic product. At this point, the user can begin to perform various processing operations on the foam plastic product. Finally, when the processing task is completed, the user first turns off the power to the static elimination mechanism 3, the lower electromagnet plate 21 and the two upper electromagnet plates 24, and then restarts the servo motor 29. The servo motor 29 drives the two upper electromagnet plates 24 to reset upwards and return to the initial position. At this point, the user can remove the processed foam plastic product from the device.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
