Description

Technical Field

[0001] This utility model relates to the field of EVA material processing, and in particular to a sheet material extraction device. Background Technology

[0002] EVA is an ethylene-vinyl acetate copolymer material. It is a non-toxic, odorless, transparent thermoplastic with excellent elasticity, flexibility, transparency, insulation, low-temperature flexural properties, weather resistance, and chemical resistance. It is widely used in the manufacture of wire and cable materials, films and other molded products and blends, automotive parts, adhesives, coatings, etc. An EVA material extraction device is a device for gripping and conveying EVA material.

[0003] In existing technologies, some sheet EVA material extraction devices require the sheet EVA material to be placed on a placement rack first. Then, the cylinder is activated to move the vacuum nozzle down through the hollow frame until the vacuum nozzle adheres to the topmost sheet EVA material. Next, the vacuum generator is activated to create negative pressure inside the vacuum nozzle, which can then grasp the EVA material. However, because the vacuum nozzle is fixed in position on the surface of the hollow frame, it is difficult to adapt to sheet EVA materials of different sizes. This results in some vacuum nozzles being idle when grasping small-sized materials, while the edge suction force of the vacuum nozzle is insufficient when grasping large-sized materials, affecting the grasping effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a sheet material extraction device to solve the problems mentioned in the background art. Due to the fixed position of the vacuum nozzle on the surface of the hollow frame, some sheet EVA material extraction devices are difficult to adapt to sheet EVA materials of different sizes. This results in some vacuum nozzles being idle when grasping small-sized materials, while the edge suction force of the vacuum nozzles is insufficient when grasping large-sized materials, thus affecting the grasping effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sheet material extraction device, including a base; A movable seat is set at the top of the base. A bidirectional lead screw is rotatably connected to the inner wall of the movable seat.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a sheet material extraction device, comprising: a base 1, a movable seat 2 at the top of the base 1, a bidirectional lead screw 201 rotatably connected to the inner wall of the movable seat 2, a guide rod 202 fixedly connected to one side of the bidirectional lead screw 201 on the inner wall of the movable seat 2, a connecting seat 203 threadedly connected to the surface of the bidirectional lead screw 201, a lifting cylinder 204 fixedly connected to the top of both the movable seat 2 and the connecting seat 203, a first adsorption seat 205 fixedly connected to the telescopic end of the lifting cylinder 204, a second adsorption seat 206 slidably connected inside the first adsorption seat 205, a driving component 207 engaged on one side of the second adsorption seat 206, a vacuum generator 208 fixedly connected to the top of the movable seat 2, and suction pipes 209 fixedly connected between the vacuum generator 208 and the first adsorption seat 205, and between the first adsorption seat 205 and the second adsorption seat 206; and a placement platform 3 fixedly installed on the surface of the base 1.

[0017] Rotating the bidirectional lead screw 201 causes it to rotate within the movable seat 2. Due to the constraint of the guide rod 202, the connecting seat 203 will move along the bidirectional lead screw 201, thereby driving the first adsorption seat 205 to move via the lifting cylinder 204. This allows the spacing between the first adsorption seats 205 to be adjusted to fit the width of the sheet EVA material. Rotating the drive component 207 causes it to rotate, thereby driving the two second adsorption seats 206 that mesh with it to slide back and forth along the inner wall of the first adsorption seat 205. This allows the spacing between the second adsorption seats 206 to be adjusted to fit the width of the sheet EVA material. The device adapts to the length of sheet EVA material, enabling it to grasp sheet EVA material of different sizes, thus improving its applicability. Activating the lifting cylinder 204 causes the first adsorption seat 205 to move downwards until the bottom ends of the first adsorption seat 205 and the second adsorption seat 206 are in contact with the topmost sheet EVA material placed on the placement platform 3. Then, the vacuum generator 208 will be activated and air will be drawn through the suction pipe 209 to create negative pressure inside the first adsorption seat 205 and the second adsorption seat 206, thereby grasping the EVA material.

[0018] Furthermore, a first adjusting motor 210 is fixedly connected to one end of the bidirectional lead screw 201. The first adjusting motor 210 is fixedly connected to the movable seat 2. A support frame 211 is fixedly connected to the top of the first adsorption seat 205 on one side of the second adsorption seat 206. A second adjusting motor 212 is fixedly connected to the top of the support frame 211.

[0019] The first adjusting motor 210 installed on one side of the movable base 2 can drive the bidirectional lead screw 201 to rotate, and the second adjusting motor 212 installed on the top of the support frame 211 can drive the drive component 207 to rotate.

[0020] Preferably, the extraction pipe 209 is a corrugated pipe, and the extraction pipe 209 is made of a material with a certain degree of elasticity.

[0021] The exhaust pipe 209 is a corrugated pipe, which allows it to extend and retract as the first adsorption seat 205 and the second adsorption seat 206 move.

[0022] Optionally, the base 1 has several through holes 103 on its surface, and the through holes 103 are circular.

[0023] The device can be fixed to the designated position by inserting a bolt into the through hole 103.

[0024] Please see Figure 3 and Figure 4 The present invention provides a technical solution: a sliding groove 301 is provided at the top of the placement platform 3, and a locking hole 302 is provided at the outer side of the sliding groove 301 at the top of the placement platform 3. A limiting plate 303 is slidably connected in the sliding groove 301, and a locking rod 304 is slidably connected in the limiting plate 303. A return spring 305 is sleeved on the surface of the locking rod 304.

[0025] Pull the locking rod 304 upward to make it slide along the limiting plate 303 and squeeze the return spring 305. While keeping the locking rod 304 stationary, pull the limiting plate 303 to make it slide along the slide groove 301. After the limiting plate 303 moves to the appropriate position, release the locking rod 304. The locking rod 304 will be inserted into the locking hole 302 under the action of the return spring 305, so that sheet EVA materials of different sizes can be fixed.

[0026] Furthermore, there are two chutes 301, which are arranged in a cross shape at the top of the placement platform 3, and the vertical cross section of the chutes 301 is T-shaped.

[0027] The vertical cross section of the slide 301 is T-shaped to prevent the limiting plate 303 from disengaging from the slide 301.

[0028] Furthermore, the locking rod 304 is U-shaped, and a stop plate 3041 is fixedly connected to the surface of the locking rod 304.

[0029] The locking lever 304 is U-shaped to facilitate pulling.

[0030] Please see Figure 1 The present invention provides a technical solution: a guide rail 101 is fixedly installed on the top of the base 1 on the outside of the movable seat 2, the movable seat 2 and the guide rail 101 are slidably connected, and a movable cylinder 102 is fixedly installed on the top of the base 1 on one side of the guide rail 101, the telescopic end of the movable cylinder 102 is fixedly connected to the movable seat 2.

[0031] After the first adsorption seat 205 and the second adsorption seat 206 grasp the sheet EVA material, the moving cylinder 102 will be activated and drive the moving seat 2 to slide along the guide rail 101, so that the sheet EVA material can be transported to the designated position.
