Description

Technical Field

[0001] This utility model relates to the field of plywood production technology, and in particular to a plywood veneer stacking device. Background Technology

[0002] In plywood production, veneer preparation is a crucial step. Logs are processed into veneers only 0.5-3mm thick through rotary cutting and slicing. The veneers then undergo drying and shearing to meet quality requirements. The processed veneers must be neatly stacked to facilitate subsequent processes such as plywood assembly and hot pressing. This stacking process not only affects production efficiency but also the final quality of the plywood.

[0003] However, existing plywood veneer stacking methods have many problems. Due to their thinness and poor rigidity, veneers are prone to deviating from the conveyor belt during stacking. This is especially true when transporting veneers at an angle upwards, where the deviation is more severe due to factors such as gravity and airflow disturbances. Once a veneer deviates from the conveyor track, it not only leads to chaotic stacking and uneven piles, affecting subsequent processes, but may also cause equipment malfunctions, increase downtime maintenance costs, and reduce production efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to provide a plywood veneer stacking device that can stably transport plywood veneers and reduce deviations during the veneer transport process.

[0006] To achieve the above objectives, this utility model proposes a plywood veneer stacking device, comprising a conveyor belt, conveyor support arms, and an adsorption positioning assembly. Two conveyor support arms are provided, with a feed roller and a discharge roller positioned between them. The conveyor belt is wound around the feed roller and the discharge roller. Two conveyor belts are provided, parallel to each other and located at the two common ends of the feed roller and the discharge roller, respectively. The adsorption positioning assembly is positioned between the two conveyor support arms and includes a slide rail, a tray, and a suction cup. The slide rail is respectively mounted on the two conveyor support arms, and both ends of the tray are connected to the two slide rails. The suction cup is mounted on the tray.

[0007] Furthermore, the pallet is provided with a lifting push rod, the suction cup is mounted on the output shaft of the lifting push rod, the bottom of the suction cup is provided with an air nozzle, and the bottom of the suction cup is provided with a transmission valve connected to the air nozzle.

[0008] Furthermore, a feed roller support is provided at the bottom of the feed roller, and the two ends of the feed roller support are rotatably connected to the two ends of the feed roller. An adjustable feed support is also provided on the feed roller.

[0009] Furthermore, the bottom of the discharge roller is provided with a discharge height adjustment rod, the top of the discharge height adjustment rod is rotatably connected to the end of the discharge roller, and the discharge roller is provided with a discharge support with an adjustable discharge angle.

[0010] Furthermore, the discharge height adjusting rod includes a hydraulic push rod or an electric telescopic rod, and there are two discharge height adjusting rods, which are located at both ends of the discharge roller, and a discharge support base is provided at the bottom of the discharge height adjusting rod.

[0012] Furthermore, both ends of the feed roller and the discharge roller are provided with rotating seats, and the rotating seats are connected to the transmission support arm.

[0013] Beneficial effects: This utility model places plywood veneers on two parallel conveyor belts, with the middle of the veneer being attracted by a suction cup.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The plywood veneer stacking device of this utility model is described below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, the plywood veneer stacking device provided in this embodiment of the present invention includes a conveyor belt 3, a conveyor support arm 5, and an adsorption positioning component 4. There are two conveyor support arms 5, and a feed roller 2 and a discharge roller 7 are arranged between the two conveyor support arms 5. The conveyor belt 3 is wound around the feed roller 2 and the discharge roller 7. There are two conveyor belts 3, which are parallel to each other and are located at the two common ends of the feed roller 2 and the discharge roller 7, respectively. A rotating seat 21 is provided at both ends of the feed roller 2 and the discharge roller 7, and the rotating seat 21 is connected to the conveyor support arm 5.

[0024] The adsorption positioning component 4 is disposed between the two transmission support arms 5. The adsorption positioning component 4 includes a slide rail 43, a tray 41 and a suction cup 42. The slide rail 43 is disposed on the two transmission support arms 5 respectively. The slide rail 43 is an electrically driven rail. The speed of the slide rail 43 is the same as the speed of the transmission belt 3. The two ends of the tray 41 are connected to the two slide rails 43 respectively. The suction cup 42 is disposed on the tray 41.

[0025] Specifically, in use, the plywood veneer stacking device of this application first places the plywood veneers on two parallel conveyor belts 3, and the middle position of the veneer is attracted by the suction cup 42 to reduce the possibility of slippage or deviation during the veneer's transport. Then, the feed roller 2 and the discharge roller 7 drive the conveyor belts 3 to move continuously, while the slide rail 43 drives the pallet 41 and the suction cup 42 to move at the same speed as the conveyor belts 3, continuously conveying the plywood veneers on the conveyor belts 3 upwards.

[0026] In one embodiment of this utility model, such as Figures 1-4As shown, a lifting push rod 45 is provided on the support plate 41, and a suction cup 42 is provided on the output shaft of the lifting push rod 45. An air nozzle 441 is provided at the bottom of the suction cup 42, and a transmission air valve 44 connected to the air nozzle 441 is provided at the bottom of the suction cup 42. The transmission air valve 44 is connected to the air passage to control the air in and out of the suction cup 42.

[0027] Specifically, after the board enters the two conveyor belts 3, as the board moves, when the board passes above the suction cup 42, the lifting push rod 45 drives the suction cup 42 to move upward, thereby causing the suction cup 42 to contact the lower surface of the board (ensuring that the suction cup 42 and the tail of the board in the conveying direction are adsorbed, so that the board is stably and completely transferred out of the discharge roller 7). Then the air nozzle 441 and the conveying air valve 44 quickly draw air, so that the suction cup 42 is firmly adsorbed to the board. Then the slide rail 43 drives the suction cup 42 to move synchronously with the conveyor belt 3.

[0028] Additionally, when the single board is conveyed to the discharge roller 7, air is reintroduced into the suction cup 42, the suction cup 42 separates from the single board, and then the lifting push rod 45 drives the suction cup 42 to retract downwards, so that the single board can be smoothly discharged.

[0029] In one embodiment of this utility model, such as Figure 1 As shown, a feed roller bracket 6 is provided at the bottom of the feed roller 2. The two ends of the feed roller bracket 6 are rotatably connected to the two ends of the feed roller 2. An adjustable feed support 1 is also provided on the feed roller 2 for guiding the single board onto the conveyor belt 3.

[0030] The bottom of the discharge roller 7 is equipped with a discharge height adjustment rod 9. The top of the discharge height adjustment rod 9 is rotatably connected to the end of the discharge roller 7. The discharge roller 7 is equipped with a discharge support 8 that can adjust the discharge angle of the single board. The discharge height adjustment rod 9 includes a hydraulic push rod or an electric telescopic rod. There are two discharge height adjustment rods 9, located at both ends of the discharge roller 7. The bottom of the discharge height adjustment rod 9 is equipped with a discharge support base 10.

[0031] Specifically, after the board enters the conveyor belt 3, the discharge height is adjusted by extending and retracting the discharge height adjustment rod 9 to support the lifting height of the end of the discharge roller 7. Furthermore, when the conveyor belt 3 is conveyed at a large angle, the suction cup 42 stably adheres to the board, effectively preventing the board from slipping off the conveyor belt 3.

[0032] To clearly illustrate the above embodiments, refer to Figures 1-4The specific working principle of the plywood veneer stacking device of this utility model is as follows: When using the plywood veneer stacking device of this application, the plywood veneer is first transferred upward through the feed tray 1 to the conveyor belt 3. The conveyor belt 3 is driven by the feed roller 2 and the discharge roller 7, which continuously transfers the veneer upward. When the veneer passes above the suction cup 42, the lifting push rod 45 drives the suction cup 42 to move upward, thereby causing the suction cup 42 to contact the lower surface of the veneer (ensuring that the suction cup 42 and the tail of the veneer are adsorbed in the transmission direction, so that the veneer on the conveyor belt 3 is stably and completely transferred out from the discharge roller 7), reducing the possibility of slippage or deviation during the transmission of the veneer.

[0033] Subsequently, the feed roller 2 and discharge roller 7 drive the conveyor belt 3 to move continuously, while the slide rail 43 drives the pallet 41 and suction cup 42 to move at the same speed as the conveyor belt 3, continuously conveying the plywood veneer on the conveyor belt 3 upwards.

[0034] When the board is conveyed to the discharge roller 7, it is transferred to the designated position via the discharge support 8. Air is reintroduced into the suction cup 42, and the suction cup 42 separates from the board. Then, the lifting push rod 45 drives the suction cup 42 to retract downwards, allowing the board to be smoothly discharged. Subsequently, the slide rail 43 drives the suction cup 42 to quickly return to its initial position.

[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
