[0026] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0027] This application provides a conveying and discharging device for paper tray production. This device is arranged in a paper tray production line and is used to transfer wet preform products produced by a forming machine. Figure 1-3 As shown, the conveying and discharging equipment 100 includes: a translation mechanism 10, a lifting mechanism 20, a conveyor 30, and a rotating mechanism 40. The lifting mechanism 20 is mounted on the translation mechanism 10, the rotating mechanism 40 is mounted on the lifting mechanism 20, and the conveyor 30 is mounted on the rotating mechanism 40. The conveyor 30 can rotate horizontally through the rotating mechanism 40 to switch the conveying direction. The lifting mechanism 20 can drive the conveyor 30 to move up and down to change the conveying height, and the translation mechanism 10 can drive the conveyor 30 to move back and forth to change the conveying position.

[0028] The translation mechanism 10 includes a translation base frame 1, a translation frame 2 slidably mounted on the translation base frame 1, and a translation cylinder 3 that is driven between the translation frame 2 and the translation base frame 1. The width of the translation frame 2 in the front-to-back direction is smaller than the width of the translation base frame 1 in the front-to-back direction, thereby enabling displacement on the translation base frame 1.

[0029] A sliding assembly 15 is provided between the translation base 1 and the translation frame 2. The sliding assembly 15 includes a slider 151 installed at the bottom of the translation frame 2 and a slide rail 152 installed on the translation base 1. The slider 151 cooperates with the slide rail 152, which extends in the front-back direction. The slider 151 can move back and forth along the slide rail 152. The translation frame 2 can move back and forth on the translation base 1 in the front-back direction under the drive of the translation cylinder 3 through the sliding engagement of the sliding assembly 15 at the bottom.

[0030] The bottom of the translation base frame 1 is equipped with several moving wheels 14. The translation base frame 1 drives the entire conveying and discharging equipment 100 to move on the ground through the moving wheels 14 at the bottom, so that it can move to a suitable work position to transfer the product.

[0031] The lifting mechanism 20 includes a lifting frame 4 located on the upper side of the translation frame 2 and a lifting cylinder 5 connected between the translation frame 2 and the lifting frame 4. The lifting cylinder 5 is used to drive the lifting frame 4 to move up and down relative to the translation frame 2 in the vertical direction, thereby changing the conveying height. It is suitable for production lines where there is a height difference between two adjacent workstations.

[0032] like Figure 2 , 4As shown in Figure 5, a guide assembly 16 is provided between the lifting frame 4 and the translation frame 2. The guide assembly 16 includes several guide posts 161 and several guide seats 162 that cooperate with each of the guide posts 161. Each guide post 161 extends vertically, and the top of each guide post 161 is connected to the lifting frame 4. The guide posts 161 are symmetrically arranged below the lifting frame 4 to ensure the balance of the lifting frame 4 during lifting. The guide seats 162 are installed on the translation frame 2, and each guide post 161 passes through the corresponding guide seat 162 and can move vertically relative to the guide seat 162. The cooperation between each guide post 161 and the corresponding guide seat 162 provides guidance for the vertical lifting of the lifting frame 4 and effectively prevents the lifting frame 4 from tilting during lifting.

[0033] The conveyor 30 is located above the lifting frame 4. The conveyor 30 includes a conveying frame 6 and a conveyor belt 7 that can be slidably engaged with the conveying frame 6. The conveying frame 6 includes a front end and a rear end that are arranged opposite each other. The conveyor belt 7 is taut on the conveying frame 6 and rotates between the front end and the rear end to transport workpieces back and forth relative to the conveying frame 6, thereby realizing automated workpiece transfer.

[0034] The conveyor frame 6 includes a pair of opposing rollers 61, which are parallel to each other and rotatably mounted at the front and rear ends of the conveyor frame 6, respectively. The conveyor belt 7 is taut between the pair of rollers 61 and is slidably engaged with the conveyor frame 6 via the pair of rollers 61.

[0035] like Figure 4-6 As shown, the rotating mechanism 40 is connected between the conveying frame 6 and the lifting frame 4 of the conveyor 30. The rotating mechanism 40 is used to drive the conveyor 30 to rotate relative to the lifting frame 4 about a center line X1 extending in the vertical direction.

[0036] The rotating mechanism 40 includes a toothed slewing bearing 8 with the center line X1 as the axis, a rack 9 meshing with the toothed slewing bearing 8, and a rotating cylinder 11 connected to the rack 9. The rotating cylinder 11 is used to drive the rack 9 to move back and forth along the tangential direction of the toothed slewing bearing 8, thereby causing the toothed slewing bearing 8 to rotate around the center line X1 by inter-tooth contact.

[0037] A fixed base plate 12, which is fixedly connected to the lifting frame 4, is installed on the lower side of the toothed slewing bearing 8, and a rotating top plate 17, which is fixedly connected to the conveying frame 6, is installed on the upper side. The toothed slewing bearing 8 is rotatably mounted on the fixed base plate 12 around the center line X1, and the rotating top plate 17 can rotate synchronously with the toothed slewing bearing 8. When the toothed slewing bearing 8 rotates around the center line X1 under the drive of the rotating cylinder 11, the conveyor 30 rotates around the center line X1 with the toothed slewing bearing 8 through the synchronous rotation of the rotating top plate 17.

[0038] A pair of proximity switches 13 are mounted on the fixed base plate 12, and the pair of proximity switches 13 are signal connected to the rotary cylinder 11. The pair of proximity switches 13 are located on the same horizontal plane on the fixed base plate 12, and there is a 90° central angle α between them. The rotating top plate 17 has a radially outward protrusion 171, which can trigger the pair of proximity switches 13. When either proximity switch 13 is triggered, the rotary cylinder 11 will drive the toothed slewing bearing 8 to reverse.

[0039] like Figure 1 , 2 As shown in Figure 6, one proximity switch 13 corresponds to the first position of the conveyor 30 when conveying in the forward and backward direction, and the other proximity switch 13 corresponds to the second position of the conveyor 30 when conveying in the left and right direction. The limiting cooperation between the pair of proximity switches 13 and the rotating top plate 17 controls the rotation of the conveyor 30 between the first and second positions with an included angle of 90°, ensuring that the conveyor belt 7 of the conveyor 30 can switch between forward and backward conveying and left and right conveying. The conveying direction can be adjusted according to the rotation of the received product, which can adapt to the transfer needs of different sites and discharge materials in a unified direction to facilitate subsequent stacking and placement by the robotic arm.

[0040] Each proximity switch 13 is also equipped with a hydraulic damper 18. The hydraulic damper 18 is used to abut against the protrusion 171 to block the continued rotation of the rotating top plate 17, and has a buffering effect to avoid violent collisions that could damage the equipment and products.

[0041] The working principle of the conveying and discharging equipment 100 is as follows: First, the lifting mechanism 20 of the conveying and discharging equipment drives the conveyor 30 to rise to receive the wet blank products produced by the molding machine; then, the conveyor 30 receiving the wet blank products descends and resets under the drive of the lifting mechanism 20; the translation cylinder 3 pushes the translation frame 2 forward, so that the conveyor 30 moves closer to the next station; the rotary cylinder 11 drives the conveyor 30 to rotate horizontally to align with the next station, and the conveyor belt 7 rotates under sliding friction to transfer the wet blank products to the next station; after the feeding is completed, the rotary cylinder 11 drives the conveyor 30 to rotate horizontally and reset; the translation cylinder 3 pushes the translation frame 2 backward to reset to the corresponding molding station of the molding machine to wait for the next wet blank product.

[0042] This application features a simple structure and stable performance, enabling it to adapt to the transfer needs of the production site. The unified discharge direction facilitates subsequent robotic palletizing and improves production efficiency.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
