Abstract
Description
Technical Field
[0001] This utility model relates to the field of plywood processing technology, specifically to an automatic feeding device for plywood processing. Background Technology
[0002] Plywood is a sheet material consisting of three or more layers of sheet material, made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It typically uses an odd number of veneer layers, with the grain direction of adjacent veneers perpendicular to each other. Automatic feeding is one of the processing steps in plywood manufacturing. Existing automatic feeding devices for plywood rely on a clamping structure combined with a lifting structure. However, using clamping to feed plywood has two drawbacks: firstly, the clamping force can easily damage the plywood surface; secondly, when the plywood is thin, clamping can be inconvenient, leading to drops and damage during clamping, increasing costs. Therefore, there is a need for an automatic feeding device that can solve the above-mentioned technical shortcomings and improve efficiency. Utility Model Content
[0003] The purpose of this utility model is to provide an automatic feeding device for plywood processing, in order to solve the problems mentioned in the background art. Existing automatic feeding devices for plywood processing rely on a clamping structure in conjunction with a lifting structure. However, when feeding plywood by clamping, on the one hand, the clamping force can easily cause damage to the surface of the plywood. On the other hand, when the plywood thickness is small, it is easy to cause inconvenience in clamping, resulting in falling and damage during clamping, which increases costs.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model relates to an automatic feeding device for plywood processing, comprising:
[0006] A lifting structure, comprising a support frame, a drive motor being installed through one side of the top of the support frame, a ball screw being fixed to the output end of the drive motor, and a support block being fixed to the movable end of the ball screw;
[0007] An automatic feeding structure includes a feeding frame fixedly connected to one end of a support block. A hydraulic cylinder is provided through the top end of the feeding frame, and threaded tubes are fixed at equal intervals at the bottom end of the feeding frame. Threaded columns are threaded inside the threaded tubes, and a connecting frame is rotatably connected to the top of the threaded columns. Guide wheels are rotatably connected at equal intervals on the upper inner side of the connecting frame.
[0008] Furthermore, the lifting structure also includes a rotating motor, the output end of which is fixed to the lower end of the bracket.
[0009] Furthermore, a positioning block is fixed to the lower end of the rotating motor, and a support plate is connected to the lower end of the positioning block by bolt thread. One end of the support plate is snapped into the lower part of the front of the plywood processing table.
[0010] Furthermore, the bracket is C-shaped, with an opening through the middle of the bracket, and a bearing seat is fixed to the lower end of the inner wall of the bracket, with the middle of the bearing seat sleeved with the lower end of the ball screw.
[0011] Furthermore, it also includes an auxiliary guiding structure, which includes a set of symmetrical threaded connecting rods on one side of the front and rear ends of the feeding frame. One end of one of the connecting rods passes through a movable motor, and the output end of the movable motor is fixed with a movable block. A protrusion is fixed on the lower inner side of the movable block, and the upper end of the protrusion and the inner side of the movable block are in contact with the plywood.
[0012] Furthermore, one end of the other connecting rod is provided with a bearing, and the output end of the rotating motor passes through the other connecting rod and extends into the middle of the bearing.
[0013] This utility model has the following beneficial effects:
[0014] This invention utilizes a drive motor to rotate a ball screw, thereby raising and lowering the loading frame. After the loading frame descends to its lowest position, the plywood to be processed, transported by a conveyor belt, is transferred to the inner side of the loading frame and guided by multiple guide wheels to reduce transmission friction and improve loading efficiency. Then, a controlled hydraulic cylinder applies pressure to maintain the stability of the structure. The output end of the hydraulic cylinder is fitted with a rubber sleeve, which, while ensuring the stability of the plywood loading structure, also prevents surface damage and helps reduce costs.
[0015] Based on the aforementioned beneficial effects, during the feeding of plywood to be processed, the inner side of the movable block and its contact with the plywood can guide and limit its movement, ensuring that the plywood inside the feeding frame is in a central position and easily maintains a stable state during feeding. After being transferred to the processing table, the movable block can be forcefully applied by a controlled rotating motor, which, together with the protrusion, lifts one end of the plywood. This allows for convenient manual control, multi-functional applicability, meets various needs, and is easy to use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0025] Please see Figure 1-4 As shown, this utility model is an automatic feeding device for plywood processing, comprising:
[0026] The lifting structure includes a support 14, a drive motor 15 is provided through one side of the top of the support 14, a ball screw 16 is fixed at the output end of the drive motor 15, and a support block 17 is fixed at the movable end of the ball screw 16.
[0027] The bracket 14 is mounted on the drive motor 15. The drive motor 15 provides the rotational power source. The ball screw 16 is used to convert the curvilinear motion into linear motion. The force is then transmitted with the help of the support block 17, which can meet the height adjustment of the feeding frame 21.
[0028] The lifting structure also includes a rotary motor 13, the output end of which is fixed to the lower end of the bracket 14;
[0029] The rotating motor 13 can apply rotational force to the bracket 14 to meet the multi-position conversion of the feeding frame 21.
[0030] A positioning block 12 is fixed to the lower end of the rotating motor 13, and a support plate 11 is connected to the lower end of the positioning block 12 by bolt thread. One end of the support plate 11 is snapped into the lower part of the front of the plywood processing table.
[0031] The positioning block 12 connects the support plate 11 to the rotating motor 13, and the connection between the support plate 11 and the plywood processing table satisfies the structural fixation of the entire device.
[0032] The bracket 14 is C-shaped and has an opening through the middle of the bracket 14. The lower end of the inner wall of the bracket 14 is fixed with a bearing 18, and the middle of the bearing 18 is sleeved with the lower end of the ball screw 16.
[0033] The opening allows the support block 17 to move up and down, and the bearing seat 18 supports the ball screw 16 and reduces rotational friction.
[0034] The automatic feeding structure includes a feeding frame 21 fixedly connected to one end of the support block 17. A hydraulic cylinder 22 is provided through the top end of the feeding frame 21, and threaded tubes 23 are fixed at equal intervals at the bottom end of the feeding frame. Threaded tubes 23 have threaded posts 24 inside, and a connecting frame 25 is rotatably connected to the top end of the threaded posts 24. Guide wheels 26 are rotatably connected to the upper end of the inner side of the connecting frame 25.
[0035] The feeding frame 21 provides an installation environment. The threaded pipe 23 supports the threaded post 24 and can be extended and adjusted up and down. The guide wheel 26 is installed with the connecting frame 25. The guide wheel 26 guides the plywood being fed and reduces the friction generated during the guidance. The upper end of the plywood is acted on by the controlled hydraulic cylinder 22 to ensure the stability of the plywood structure.
[0036] Working principle: The angle of the bracket 14 is adjusted by the controlled rotary motor 13, and the rotational force is applied to the ball screw 16 by the controlled drive motor 15, so that the loading frame 21 moves down. After the loading frame 21 moves down to the lower end and is level with the external feeding conveyor belt, the plywood driven by the conveyor belt is pushed to the inside of the loading frame 21 and guided by multiple guide wheels 26 to move smoothly to the inside of the loading frame 21. At this time, the output end is moved down by the controlled hydraulic cylinder 22. A rubber sleeve is fitted at the lower end of the output end. With the help of the resistance applied to the upper end of the plywood, the drive motor 15 and the rotary motor 13 are reversed, so that the loading frame 21 moves to the top of the plywood processing table and moves down again.
[0037] This solution ensures the structural stability of the plywood during the feeding process and avoids damage to its surface, which helps reduce costs, facilitates use, and meets requirements.
[0038] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:
[0039] It also includes an auxiliary guiding structure, which includes a set of symmetrical threaded connecting rods 31 on one side of the front and rear ends of the feeding frame 21. One end of a connecting rod 31 passes through a movable motor 32, and the output end of the movable motor 32 is fixed with a movable block 33. The lower inner part of the movable block 33 is fixed with a protrusion 34, and the upper end of the protrusion 34 and the inner side of the movable block 33 are in contact with the plywood.
[0040] The connecting rod 31 accommodates the installation of the movable motor 32 and the bearing seat 18. The controlled movable motor 32 provides the power source required for the rotation of the movable block 33. The movable block 33 limits the position of the plywood being fed, ensuring that the plywood is in the center of the inner side of the feeding frame 21. On the other hand, it works with the protrusion 34 to lift one end of the plywood to facilitate structural control.
[0041] One end of the other connecting rod 31 is provided with a bearing, and the output end of the rotating motor 13 passes through the other connecting rod 31 and extends into the middle of the bearing;
[0042] The bearing supports the output end of the movable motor 32 and can reduce rotational friction.
[0043] Working principle: When the plywood is loaded onto the inside of the loading frame 21, the loading is limited by the contact between the inside of the movable block 33 and the plywood in the loading process. After the plywood is loaded onto the processing table, the movable block 33 can be forced by the controlled movable motor 32, and the protrusion 34 can be rotated in conjunction, so that one end of the plywood can be lifted up to facilitate subsequent manual unloading.
[0044] This solution meets the requirements for loading and unloading plywood, facilitates multi-functional use, and improves the applicability of the structure.
