They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] Please see Figures 1-8 The automatic stacking and receiving device for PVC flooring production shown includes a frame 1, a conveying device 2, a stacking device 3, and a supporting device 4. The conveying device 2 is mounted on the frame 1 to transfer the boards to the stacking device 3. The stacking device 3 is mounted at one end of the conveying device 2 to stack the boards and transfer them to the supporting device 4. The supporting device 4 is used to receive the boards transferred from the stacking device 3.

[0037] The stacking device 3 includes a set of symmetrically arranged first guide rods 301. The two ends of the first guide rods 301 are connected to the two sides of the frame 1. A set of material-picking components 302 is provided on each side of the first guide rods 301, and the two material-picking components 302 are symmetrically arranged on the first guide rods 301. By movably setting the material-picking components 302 on the first guide rods 301, the distance between the two material-picking components 302 can be adjusted, making it suitable for collecting materials of different widths and improving the versatility of the equipment.

[0038] Specifically, the material handling assembly 302 includes a cylinder bracket 3021, a material handling cylinder 3022, a first connecting rod 3023 with a V-shaped structure, a first connecting rod seat 3024, a second connecting rod 3025, a second connecting rod seat 3026, a material handling plate 3027, and a vertical plate 3028.

[0039] The vertical plate 3028 is connected to the first guide rod 301 via a linear bearing. The cylinder bracket 3021 has an inverted "L"-shaped structure. The base of the picking cylinder 3022 is movably connected to the cylinder bracket 3021. One end of the first connecting rod 3023 is movably connected to the telescopic rod of the picking cylinder 3022. The bottom end of the first connecting rod 3023 is movably connected to the first connecting rod seat 3024. The end of the first connecting rod 3023 near the second connecting rod 3025 is movably connected to the second connecting rod 3025. The second connecting rod 3025 is movably connected to the second connecting rod seat 3026. The second connecting rod seat 3026 is fixedly set in the middle position of the picking plate 3027. Both ends of the picking plate 3027 are connected to the side of the vertical plate 3028 via bearing hinges. The picking plate has a long strip structure with a V-shaped cross section.

[0040] When material is being picked up, the picking cylinder 3022 is activated, and its telescopic rod extends to push the first connecting rod 3023 downward. The first connecting rod 3023 rotates, which in turn pulls the second connecting rod 3025 to rotate. The second connecting rod 3025 pulls the picking plate 3027 to flip upward, thereby catching the plate coming from the conveying device 2. Then, the telescopic rod of the picking cylinder 3022 retracts, and the first connecting rod 3023 is driven to rotate in the opposite direction, thereby pushing the second connecting rod 3025 to flip the picking plate 3027 downward, so as to drop the plate onto the supporting device 4.

[0041] The supporting device 4 includes a lead screw drive pair 401, a lead screw motor 402, two second guide rods 403 arranged symmetrically on the left and right, two support plates 404 arranged symmetrically on the frame 1, a connecting plate 405, and a material support arm 406. The lead screw motor 402 is mounted on the frame 1 and is connected to the lead screw on the lead screw drive pair 401 via a coupling to provide rotational power to the lead screw on the lead screw drive pair 401. The lead screw nut seat on the lead screw drive pair 401 is connected to the middle of the connecting plate 405. The two ends of the connecting plate 405 are connected to the second guide rods 403 respectively via linear bearings. The two ends of the two second guide rods 403 are connected to the two support plates 404. A set of material support arms 406 is symmetrically arranged to support stacked plates.

[0042] When the number of plates stacked on the stripping arm 406 reaches a certain amount, the lead screw 402 is activated, which drives the lead screw transmission pair 401 to rotate, thereby causing the stripping arm 406 set on the connecting plate 406 to move downward and drop the stacked plates onto the transfer car.

[0043] Specifically, the conveying device 2 includes a first roller 201, a drive motor 202, auxiliary wheels 203, a connecting shaft 204, and a synchronous belt 205. The first roller 201 and the second roller 202 are both connected to the side of the frame 1 through bearings. There are multiple first rollers 201, and each first roller 201 has a first pulley 206 on the end near the drive motor 202. There are multiple auxiliary wheels 203, and each auxiliary wheel 203 is connected to the connecting shaft 204 through bearings. The connecting shaft 204 is connected to the end of the frame 1 near the drive motor 202. The multiple first pulleys 206 are connected to each other through the synchronous belt 205. One of the multiple first pulleys 206 also has a sprocket 207 on its outer side. The shaft of the drive motor 202 is connected to the sprocket 207 through the sprocket and chain connection.

[0044] In this embodiment, the conveying device drives multiple first rollers 201 to rotate together via a drive motor 202 and a synchronous belt 205, thereby achieving the purpose of conveying the sheet material.

[0045] Specifically, the conveying device 2 also includes an extrusion conveying assembly 208, which includes an upper extrusion roller 2081, a lower extrusion roller 2082, an adjusting frame 2083, and a slider 2084 that can be adjusted up and down in the adjusting frame 2083. The slider 2084 is bolted to the upper frame of the adjusting frame 2083. The adjusting frame 2083 has a set of rollers symmetrically arranged on both sides of the frame 1. The two ends of the upper extrusion roller 2081 are connected to the slider 2084 through bearings. The two ends of the lower extrusion roller 2082 are connected to both sides of the frame 1 through bearings. The lower extrusion roller 2082 has a second pulley 2085 at one end near the drive motor 202. The second pulley 2085, the first pulley 206, and the auxiliary wheel 203 are connected by a synchronous belt 205.

[0046] In this embodiment, the extrusion conveying component 208 is designed to stably input the sheet material onto the material taking component 302, avoiding the situation where the sheet material cannot smoothly enter the material taking component 302 due to vibration.

[0047] Specifically, the frame 1 has a material picking area on the side near the support device 4. A transfer vehicle is provided in the material picking area, and the frame 1 has limit blocks 5 on both sides of the bottom of the transfer vehicle. Each limit block 5 is equipped with a rolling shaft 6, and the rolling shaft 6 is movably connected to the limit block 5.

[0048] In this implementation scheme, in order to allow the transfer vehicle to accurately enter the material picking area, a limit block 5 is set to restrict the position of the transfer vehicle, and a rolling shaft 6 is set to prevent the side of the transfer vehicle from causing excessive impact on the frame 1.

[0049] Specifically, an open-type fixing clip 3029 is provided on one side of the linear bearing that connects the vertical plate 3028 to the first guide rod 301. The fixing clip 3029 is set on the first guide rod 301.

[0050] In this implementation scheme, the vertical plate 3028 is fixed by the fixing bracket 3029 to prevent it from moving easily, thus serving as a limit.

[0051] Working principle: First, the sheet material is transferred to the conveyor 2 of this device via the front-end conveying equipment. Multiple first rollers 201 on the conveyor 2 rotate, moving the sheet material onto the extrusion conveying assembly 208 of this device. The extrusion conveying assembly 208 smoothly conveys the sheet material towards the material-taking assembly 302. Simultaneously, the two material-taking assemblies 302 operate concurrently. Specifically, the material-taking cylinder 3022 on the material-taking assembly 302 operates, extending the telescopic rod and pressing the first connecting rod 3024 downwards. The first connecting rod 3024 pulls the second connecting rod 3025 to rotate in the direction of the first connecting rod 3024, thereby pulling the material-taking plate 3027 upwards and flipping it over. The sheet material conveyed by the extrusion conveying assembly 208 falls onto the material-taking plate 3027. Then, the telescopic rod of the picking cylinder 3022 retracts, pulling the first connecting rod 3023 upward. The first connecting rod 3023 is pushed back by the pulled-out second connecting rod 3025, thereby flipping the picking plate 3027 downward, so that the board falls onto the support arm 406 on the unloading device 4. The picking component 302 repeats its work to stack multiple boards onto the support arm 406. When a certain number of boards have been stacked, the lead screw motor 402 operates, driving the lead screw transmission pair 401 to work, driving the connecting plate 405 downward, thereby placing the stacked boards onto the transfer car, thus achieving the purpose of automatic stacking and receiving.
