Description

Technical Field

[0001] This utility model relates to the technical field of paper tray processing devices, and more specifically, it relates to a paper tray feeding structure. Background Technology

[0002] The production of paper trays involves multiple processes, including feeding, thermoforming, and unloading. The unloading process refers to removing the formed paper trays from the mold and transferring them to the next workstation or collection area. Traditional unloading methods often use manual handling or simple pneumatic suction cups, which suffer from low efficiency, inaccurate positioning, and easy damage to the product.

[0003] Currently, paper tray unloading commonly uses an air-blowing method, which involves using compressed air to blow the formed paper trays off the mold or directly to the collection area. However, this air-blowing unloading method has several drawbacks: First, the airflow direction is difficult to control precisely, and the paper trays are prone to deflection or drifting under the influence of the airflow, failing to fall accurately into the predetermined position, leading to difficulties in positioning subsequent processes; second, unstable or excessively high air pressure can easily break or deform the paper trays, affecting product quality; third, when multiple workstations are producing simultaneously, the airflow from each workstation may interfere with each other, causing the paper trays to fail to detach from the mold properly or fall into the wrong position; in addition, the air-blowing method generates significant noise and easily stirs up dust, affecting the working environment and the health of operators.

[0004] Therefore, there is an urgent need for a compact paper tray feeding structure that can achieve compound motion and has a low cost, in order to improve the overall automation level and production efficiency of the rotary processing device production line. Utility Model Content

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0028] A paper tray unloading structure includes a base 1. A feeding component 2, a processing component 3, and a transport component 4 are mounted on the base 1. The transport component 4 moves the raw material from the feeding component 2 to the processing component 3 for processing. A moving component is also mounted on the base 1 for removing the formed paper tray from the processing component 3 and transferring it to the next workstation.

[0029] The movable assembly includes a movable base 5 fixed to the base 1. A movable rod 51 is rotatably mounted on the movable base 5, and a rotating disk 52 is fixed to the movable rod 51. A gripping rod 53 is connected to the rotating disk 52. Several suction elements 54 are provided at the end of the gripping rod 53 away from the rotating disk 52. A first half-gear 55 is also formed on the movable rod 51. Lifting blocks 56 are also provided at both ends of the first half-gear 55 on the movable base 5. Each lifting block 56 is provided with an adjusting block 59 and a second half-gear 57. The second half-gear 57 meshes with both ends of the first half-gear 55. The adjusting block 59 is elliptical, and its upper end abuts against the rotating disk 52, for driving the rotating disk 52 to move axially along the movable rod 51.

[0030] When the moving rod 51 rotates, the first half gear 55 drives the second half gears 57 on both sides to rotate synchronously, which in turn drives the elliptical adjusting block 59 to rotate. As the major and minor axes of the adjusting block 59 change alternately, its top end causes the rotating disk 52 to rise and fall periodically, thereby driving the gripping rod 53 to achieve lifting and lowering motion while rotating. That is, the gripping rod 53 can swing in the horizontal plane and move up and down at the same time, realizing a compound motion.

[0031] The moving assembly also includes a speed reducer connected to the drive unit. The speed reducer is positioned between the drive unit and the moving rod 51 and is used to adjust the rotational speed and torque of the moving rod 51. Through the speed reduction and torque amplification effect of the speed reducer, the gripping rod 53 achieves a smoother operating speed during rising, rotating, and falling, preventing the paper tray from shaking or falling off due to excessive speed or insufficient torque. Simultaneously, the speed reducer ensures more precise positioning of the gripping rod 53 when swinging to the next station, facilitating accurate placement of the paper tray and effectively improving the stability and reliability of the unloading process.

[0032] like Figure 2 As shown, the suction component 54 includes a suction sleeve 541. The suction sleeve 541 is fixed to the gripping rod 53. A suction head 543 is provided inside the suction sleeve 541, and one end of the suction head 543 forms a suction end for gripping the paper tray. A connecting channel 544 for connecting an air valve is also formed inside the suction sleeve 541, and a suction hole 545 that mates with the connecting channel 544 is formed on the gripping rod 53. During operation, the external air valve controls the vacuum adsorption of the suction end through the connecting channel 544 and the suction hole 545 to realize the gripping and release of the paper tray.

[0033] exist Figure 1 and Figure 3 As shown, the feeding assembly 2 includes a support frame 6 and a feeding section. The support frame 6 includes a fixing rod 61 fixed to the base 1, and a feeding plate 62 is provided on the fixing rod 61. A discharge hole 63 is formed on the feeding plate 62. Positioning members are also provided on the feeding plate 62, and at least four positioning members are provided around the discharge hole 63 (eight in this embodiment), with gaps between each positioning member for placing raw materials. When the paper tray raw materials are stacked on the feeding plate 62, the four positioning members limit their movement circumferentially to prevent displacement.

[0034] The positioning component includes a positioning block 64 and a positioning post 65. A locking hole is formed at one end of the positioning block 64, and the positioning post 65 is fixed within the locking hole. An adjustment gap is formed at the end of the positioning block 64 away from the locking hole, allowing the positioning block 64 to have a certain adjustment capability, enabling fine-tuning of the radial position of the positioning post 65 according to the thickness or diameter of the raw material. A flexible hose 7 is also provided on the base 1, located between the positioning posts 65, providing elastic cushioning during raw material stacking. A bend 653 is formed at the end of the positioning post 65 away from the loading plate 62, the bend 653 bending outwards to facilitate the insertion of raw materials.

[0035] like Figure 1As shown, the processing component 3 includes a lower mold 9 fixed to the base 1. A driving component and an upper mold 91 are also provided on the base 1. The driving component connects to the upper mold 91 and drives the upper mold 91 to move towards the lower mold 9. A moving block 92 connected to the upper mold 91 is also provided on the base 1. The moving block 92 has an adjustment gap, and an adjustment protrusion fixed within the adjustment gap is formed on the upper mold 91. Through the cooperation of the adjustment gap on the moving block 92 and the adjustment protrusion, the installation position of the upper mold 91 can be finely adjusted to ensure precise alignment between the upper mold 91 and the lower mold 9.

[0036] like Figure 1 As shown, the transport component 4 includes a moving track 42 and a suction cup 43. The suction cup 43 is located at the bottom of the loading component 2 and is connected to a movable rod 44. A lifting part connected to the movable rod 44 is provided on the base 1 for driving the suction cup 43 to rise and fall. A driving component is also provided on the base 1, which is connected to and drives the moving track 42 to move. The driving component includes a driving cylinder 45 and a driving rod 46. When picking up material, the driving cylinder 45 drives the moving track 42 to move directly below the suction cup 43, the lifting part drives the suction cup 43 to rise, and picks up a sheet of raw material from the discharge hole 63 of the loading plate 62; after the suction cup 43 picks up the raw material, the lifting part drives the suction cup 43 to fall and place the raw material on the moving track 42; the moving track 42 then transfers the raw material to the lower mold 9 position of the processing component 3.

[0037] Reference Appendix Figure 1 After the paper tray is processed, the moving rod 51 rotates, and through the meshing of the first half gear 55 and the second half gear 57, the elliptical adjusting block 59 rotates, pushing the rotating disk 52 and the gripping rod 53 to rotate and rise simultaneously, so that the suction end of the suction element 54 contacts the paper tray and adsorbs it. Then the moving rod 51 rotates in the opposite direction, the gripping rod 53 descends and swings to the next station or collection area, and the paper tray is released. The above cycle is repeated to achieve automated feeding. The use of a suction element to replace the air blowing method completely solves the problems of paper tray drifting, breakage, and inaccurate positioning in air blowing feeding, improving efficiency and product quality.
