Description

Technical Field

[0001] The present application relates to the field of foam sheet cutting technology, and in particular to an EVA foam sheet cutting device. Background Art

[0002] EVA (ethylene-vinyl acetate copolymer) foam sheets have excellent cushioning, shock resistance, heat insulation, sound insulation and other properties. Usually, EVA foam sheets need to be precisely cut to meet different application requirements.

[0003] The traditional cutting device uses a set of rotating rollers to drive the foam sheet toward the blade of the cutting device, so that the foam sheet is passively cut into the required thickness. During the cutting process, the foam sheet needs to be manually passed to the rollers. The rollers contact the foam sheet and drive the foam sheet to pass through the rollers. In mass production, this operation mode consumes a lot of manpower and is inefficient, which is not conducive to mass production. Utility Model Content

[0004] In order to reduce the problems of high labor consumption and low efficiency in the foam sheet cutting process, the present application provides an EVA foam sheet cutting device.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses an EVA foam sheet cutting device. Figure 1 and Figure 2 The EVA foam sheet cutting device includes a frame 1, which serves as the basic supporting structure of the entire device and is made of solid metal material to ensure overall stability and load-bearing capacity. A guide frame 2 is provided on the top of the frame 1, and the guide frame 2 is composed of a bracket 21 and an inclined guide plate 23. The bracket 21 is fixedly connected to the frame 1, and its upper surface is flat, and is used to support the EVA foam sheet. The inclined guide plate 23 is installed above the front end of the bracket 21, at a certain inclination angle, so that the EVA foam sheet placed on the bracket 21 can be smoothly introduced into the cutting device 15.

[0033] The arm 12 is movably arranged on the frame 1. In order to control the movement of the arm 12, a control device is installed on the frame 1. The control device includes a slide 11 horizontally slidably arranged on the frame 1, and the slide 11 can move closer to or away from the cutting device 15. One end of the arm 12 is connected to the side wall of the frame 1 through a bearing or a similar mechanism, so that it can swing freely within a certain range. The frame 1 is provided with a driving component 3 for controlling the movement of the slide 11 and a flip component 4 for controlling the rotation of the arm 12.

[0034] The driving assembly 3 includes a motor 31 fixedly connected to the frame 1, a screw 32 coaxially fixedly connected to the output shaft of the motor 31, the screw 32 rotatably connected to the frame 1, and the screw 32 penetrates the slide 11 and is threadedly connected to the slide 11. The operator can drive the screw 32 to rotate by controlling the motor 31, thereby driving the slide 11 to move to a specified position along the axial direction of the screw 32.

[0035] like Figure 2 and Figure 3 The flip assembly 4 includes an electric cylinder 41 hinged on the slide 11, and the output shaft of the electric cylinder 41 is hinged on the support arm 12. The operator can control the extension and retraction of the output shaft of the electric cylinder 41 to control the flip angle of the support arm 12.

[0036] A clamping portion is provided at the end of the support arm 12 to fix the EVA foam sheet. In this embodiment, the clamping portion adopts a vacuum suction cup 13 structure, and negative pressure is generated by a vacuum pump to firmly adsorb the EVA foam sheet on the vacuum suction cup 13. In order to ensure the stability of the clamping, the number and distribution of the vacuum suction cups 13 are designed according to the size and shape of the EVA foam sheet to ensure that it can be fully covered and firmly adsorbed.

[0037] In order to further improve the feeding flexibility, the free end of the support arm 12 is also hinged with a connecting rod 14. The other end of the connecting rod 14 is connected to the clamping part, and an elastic component 5 is arranged between the two. The elastic component 5 includes a telescopic rod 51 hinged between the support arm 12 and the connecting rod 14, and a spring 52 is sleeved on the telescopic rod 51, and the spring 52 is used to push the support arm 12 and the connecting rod 14 to move away from each other.

[0038] When the support arm 12 moves to the specified position, the contact position and angle between the clamping part and the EVA foam sheet can be adjusted by controlling the swing angle of the support arm 12 to ensure the accuracy and stability of the clamping. At the same time, the presence of the elastic component 5 enables the clamping part to adapt to EVA foam sheets of different thicknesses, thereby improving the adaptability and practicality of the device.

[0039] In addition, in order to further improve the degree of automation of feeding, a conveyor belt 22 can be set on the bracket 21. The EVA foam sheet can be continuously and stably conveyed to the bottom of the guide frame 2. When the EVA foam sheet reaches the specified position, the control device is started, driving the support arm 12 and the clamping part to move above the EVA foam sheet, and the vacuum suction cup 13 adsorbs it and moves it to the bracket 21. Under the action of the conveyor belt 22, the EVA foam sheet is conveyed toward the guide plate and sent into the cutting device 15.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
