Description

Technical Field

[0001] This utility model relates to the field of static electricity removal equipment technology, specifically to a surface static electricity treatment device for manufacturing EPP buffer components. Background Technology

[0002] EPP cushioning components are cushioning parts made of expanded polypropylene (EPP) and are widely used in many fields. Due to their lightweight, high impact resistance, chemical corrosion resistance, and recyclability, EPP cushioning components are widely used in the protection of precision components in the automotive, electronics, and packaging industries. However, during the manufacturing process of EPP cushioning components, the material surface is prone to static electricity accumulation due to friction or environmental factors, which can lead to adsorption and contamination. Static electricity can also reduce the adhesion of subsequent processes (such as spraying, printing, or bonding), reduce production yield, and may cause discharge, posing a threat to sensitive electronic components or flammable environments.

[0003] Therefore, there is an urgent need for a surface electrostatic treatment device for manufacturing EPP buffer components. However, existing equipment cannot process in batches, has low processing efficiency, and lacks a fixed positioning for EPP buffer components, which makes them prone to movement during the electrostatic removal process, thus reducing the effectiveness of the electrostatic removal treatment. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a surface electrostatic treatment device for manufacturing EPP buffer components.

[0005] The technical solution of this utility model is: a surface electrostatic treatment device for manufacturing EPP buffer components, including a lower mounting platform, an upper mounting platform connected to the lower mounting platform at both ends by hydraulic cylinders, several fastening boxes disposed on the lower mounting platform with an open structure at the upper end, and a fastening cover disposed at the bottom end of the upper mounting platform and corresponding to each of the fastening boxes.

[0006] The fastening box includes a fixed base box and a movable base box whose bottom end extends into the fixed base box and can slide up and down along the inner wall of the fixed base box. The bottom end of the movable base box is provided with a metal frame.

[0007] The bottom periphery of the fastening cover is equipped with several electromagnetic chucks, and the bottom of the inside of the fastening cover is connected to a plasma spray gun via an electric telescopic rod.

[0008] Furthermore, the lower mounting platform has parallel adjusting vertical grooves on its upper left and right sides, and each adjusting vertical groove has a sliding mounting block slidably connected to it. The hydraulic cylinder is connected to the upper end of the corresponding sliding mounting block.

[0009] Note: When placing EPP buffers requiring electrostatic treatment in each snap-fit ​​box, to avoid obstruction by the upper mounting platform and its bottom components, the operator can push the upper mounting platform backward. At this time, the mounting sliding block at the bottom of the hydraulic cylinder slides backward in the adjusting vertical groove, ensuring the normal placement of the EPP buffers. This structure only needs to slide horizontally to free up operating space, without occupying additional vertical height, making it suitable for compact production environments.

[0010] Furthermore, the inner wall of the snap-fit ​​cover is provided with a dust collection cover, and the bottom of the upper mounting platform is provided with a dust collection box, which is connected to the dust collection cover via a connecting hose.

[0011] Instructions: When the snap-fit ​​cover abuts against the upper end of the corresponding snap-fit ​​box, the surface of the EPP buffer component is subjected to plasma antistatic treatment using a plasma spray gun. During the treatment, a large amount of dust is generated in the air. Air is introduced into the dust collection box through the dust collection hood and connecting hose for dust removal. The treated air is then discharged. The combination of the dust collection box, connecting hose, and dust collection hood effectively collects the large amount of dust generated during the antistatic treatment, preventing dust from spreading in the surrounding environment, maintaining the cleanliness of the work area, and reducing environmental pollution.

[0012] Furthermore, the bottom of the movable base box is provided with a limiting sliding frame that can slide up and down along the inner wall of the fixed base box, and the fixed base box and the limiting sliding frame are connected by several buffer springs.

[0013] Explanation: When the electromagnetic chucks at the bottom of the snap-fit ​​cover adsorb the metal frame at the top of the mobile base box, the hydraulic cylinder adjusts the placement space between the snap-fit ​​cover and the mobile and fixed base boxes to ensure that the EPP buffer can be fully enclosed within the placement space for surface plasma antistatic treatment. After the treatment is completed, the electromagnetic chucks are de-energized and separated from the mobile base box. At this time, the buffer springs buffer the gravity of the mobile base box as it slides downward, reducing the collision and impact between the mobile and fixed base boxes, and reducing the risk of wear and damage to equipment components. The limiting sliding frame allows the mobile base box to slide up and down along the inner wall of the fixed base box, avoiding shaking or displacement during movement and ensuring the stability of the equipment structure.

[0014] Furthermore, the lower mounting platform is provided with support legs at the four corners of its bottom, and each support leg is provided with a horizontal stabilizing plate at its bottom, and the bottom of the horizontal stabilizing plate is provided with an anti-slip pad.

[0015] Note: The horizontal stabilizing plate increases the contact area between the equipment and the ground, and the anti-slip mat can significantly increase the friction between the horizontal stabilizing plate and the ground, effectively preventing the equipment from sliding on the ground and making the equipment support more stable.

[0016] The beneficial effects of this utility model are:

[0017] This utility model discloses a surface electrostatic treatment device for manufacturing EPP buffer components. During use, several EPP buffer components are simultaneously positioned and restrained by various locking boxes, forming a relatively enclosed placement space with locking covers. This prevents the EPP buffer components from easily moving during the electrostatic removal process, thus avoiding a reduction in the treatment effect. It also ensures that the EPP buffer components are fully enclosed within the placement space for surface plasma electrostatic removal. Furthermore, during the treatment process, the combination of a dust collection box, connecting hose, and dust collection cover effectively collects the large amount of dust generated during the electrostatic removal process, preventing dust from spreading in the surrounding environment, maintaining the cleanliness of the work area, and reducing environmental pollution. Since the locking boxes and locking covers are fixedly connected by electromagnetic chucks, when it is necessary to adjust the height of the placement space according to different sizes of EPP buffer components, the extension and retraction of the hydraulic cylinder, combined with the sliding action of the movable base box along the inner wall of the fixed base box, achieves the purpose of adjusting the height of the placement space, thus adapting to the processing needs of EPP buffer components of different sizes.

Detailed Implementation

[0022] Example 1: As Figure 1 , 2 As shown, a surface electrostatic treatment device for manufacturing EPP buffer components includes a lower mounting platform 1, an upper mounting platform 2 connected to the lower mounting platform 1 at its left and right ends respectively by hydraulic cylinders 20, two fastening boxes 3 located on the lower mounting platform 1 with open structures at their upper ends, and fastening covers 4 located at the bottom of the upper mounting platform 2 and corresponding one-to-one with the fastening boxes 3. The hydraulic cylinders 20 adopt existing technology, such as Y-HG1 series hydraulic cylinders.

[0023] The snap-fit ​​box 3 includes a fixed base box 30 and a movable base box 31 whose bottom end extends into the fixed base box 30 and can slide up and down along the inner wall of the fixed base box 30. The bottom end of the movable base box 31 is provided with a metal frame 310, wherein the metal frame 310 adopts an existing rectangular frame structure and can be made of carbon steel.

[0024] The bottom periphery of the snap-fit ​​cover 4 is provided with 6 electromagnetic chucks 40, and the bottom of the snap-fit ​​cover 4 is connected to a plasma spray gun 42 via an electric telescopic rod 41. The electromagnetic chucks 40 and the plasma spray gun 42 both adopt existing technologies. For example, the electromagnetic chucks 40 can be the SDX-3 type electromagnetic chucks, and the plasma spray gun 42 can be the PSM-AJP-1K type plasma spray gun.

[0025] The lower mounting platform 1 has parallel adjusting vertical grooves 10 on its upper left and right sides. Each adjusting vertical groove 10 is slidably connected to a mounting sliding block 11. The hydraulic cylinder 20 is connected to the upper end of the corresponding mounting sliding block 11. When it is necessary to place EPP buffers that need to be electrostatically treated in each snap-fit ​​box 3, in order to avoid the obstruction of the upper mounting platform 2 and the components installed at its bottom, the operator can push the upper mounting platform 2 backward. At this time, the mounting sliding block 11 at the bottom of the hydraulic cylinder 20 slides backward in the adjusting vertical groove 10, ensuring the normal placement of the EPP buffers. This structure only needs to slide horizontally to free up operating space, without occupying additional vertical height, and is suitable for compact production environments. The hydraulic cylinder 20 adopts existing technology, such as the TFRH type hydraulic cylinder.

[0026] The inner wall of the snap-fit ​​cover 4 is provided with a dust collection cover 43, and the bottom of the upper mounting platform 2 is provided with a dust collection box 44. The dust collection box 44 is connected to the dust collection cover 43 through a connecting hose 45. When the snap-fit ​​cover 4 abuts against the upper end of the corresponding snap-fit ​​box 3, the surface of the EPP buffer is subjected to plasma antistatic treatment by a plasma spray gun 42. During the treatment, a large amount of dust will be generated in the air. The air is introduced into the dust collection box 44 through the dust collection cover 43 and the connecting hose 45 for dust removal treatment. The treated air is discharged. Through the combination of the dust collection box 44, the connecting hose 45 and the dust collection cover 43, a large amount of dust generated during the antistatic treatment can be effectively collected, preventing the dust from spreading in the surrounding environment, keeping the work area clean and hygienic, and reducing environmental pollution. The dust collection box 44 adopts existing technology, such as the existing cyclone dust collection box.

[0027] like Figure 3As shown, the bottom of the movable base box 31 is provided with a limiting sliding frame 311 that can slide up and down along the inner wall of the fixed base box 30. The fixed base box 30 and the limiting sliding frame 311 are connected by eight buffer springs 312. When each electromagnetic chuck 40 at the bottom of the snap-fit ​​cover 4 adsorbs the metal frame 310 at the top of the movable base box 31, the extension and retraction of the hydraulic cylinder 20 adjusts the placement space between the snap-fit ​​cover 4 and the movable base box 31 and the fixed base box 30, ensuring that the EPP buffer can be fully enclosed in the placement space for surface plasma antistatic treatment. After the treatment is completed, the electromagnetic chuck 40 is de-energized and separated from the movable base box 31. At this time, the buffer springs 312 buffer the gravity of the movable base box 31 when it slides down, reducing the collision and impact between the movable base box 31 and the fixed base box 30, reducing the risk of wear and damage to equipment components. The limiting sliding frame 311 allows the movable base box 31 to slide up and down along the inner wall of the fixed base box 30, avoiding shaking or displacement during movement and ensuring the stability of the equipment structure.

[0028] Support legs 12 are provided at the four corners of the bottom of the lower installation platform 1. Each support leg 12 is provided with a horizontal stabilizing plate 13 at its bottom end. The bottom end of the horizontal stabilizing plate 13 is provided with an anti-slip pad 130. The horizontal stabilizing plate 13 can increase the contact area between the equipment and the ground, and the anti-slip pad 130 can significantly increase the friction between the horizontal stabilizing plate 13 and the ground, effectively preventing the equipment from sliding on the ground, and making the support of the equipment more stable.

[0029] The method of using the surface electrostatic treatment equipment for manufacturing EPP buffer components according to this utility model includes the following steps:

[0030] S1. Place the EPP buffer to be processed into each fixed base box 30. Then, the worker can push the upper installation platform 2. At this time, the installation sliding block 11 at the bottom of the hydraulic cylinder 20 slides in the adjusting vertical groove 10, so that each fastening cover 4 is located at the top of the corresponding fixed base box 30.

[0031] S2. The hydraulic cylinder 20 drives the upper mounting platform 2 and the fastening cover 4 installed at the bottom of the upper mounting platform 2 to move downwards, and powers each electromagnetic chuck 40 and plasma spray gun 42. When each electromagnetic chuck 40 adsorbs the metal frame 310 at the upper end of the movable base box 31, the hydraulic cylinder 20 adjusts the placement space between the fastening cover 4 and the movable base box 31 and the fixed base box 30 to ensure that the EPP buffer can be fully enclosed in the placement space. The plasma spray gun 42 is used to remove static electricity from the surface of the EPP buffer.

[0032] S3. During the process, a large amount of dust will be generated in the air. The air is introduced into the dust collection box 44 through the dust collection hood 43 and the connecting hose 45 and the dust is removed. The treated air is then discharged.

[0033] S4. After processing is completed, the electromagnetic chuck 40 is de-energized and separated from the metal frame 310 at the upper end of the movable base box 31. At this time, the upper mounting platform 2 and the fastening cover 4 installed at the bottom of the upper mounting platform 2 are driven to move upward by the hydraulic cylinder 20. The buffer spring 312 buffers the gravity when the movable base box 31 slides downward. Finally, the processed EPP buffer can be taken out.
