[0017] 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.

[0018] This application provides a rotary drum hot pressing shaping device, which is used to continuously hot press and shape irregular products after drying and trim them. It can automatically complete the hot pressing shaping, storage and sorting of products, effectively reducing manual labor, reducing the difficulty of operation and improving production efficiency.

[0019] like Figure 1 , 2As shown, the rotary drum hot pressing shaping equipment 100 includes: a hot press 10, a rotary drum device 20 installed below the hot press 10, an elevator 30 installed on the rear side of the rotary drum device 20, and a material handling machine 40 installed on the rear side of the elevator 30.

[0020] like Figure 1-4 As shown, the hot press 10 includes an upper mold 1 that can move up and down and a drive device 2 that is connected to the upper mold 1 in a transmission. The upper mold 1 has a rising position and a pressing position below the rising position in the vertical direction. The drive device 2 is used to drive the upper mold 1 to move back and forth between the rising position and the pressing position.

[0021] The hot press 10 also includes multiple guide pillars 3 extending in the vertical direction, an upper plate 4 mounted on top of the guide pillars 3, and a middle plate 5 movably mounted on the guide pillars 3 in the vertical direction. An upper mold 1 is mounted on the middle plate 5, and a drive device 2 is mounted on the upper plate 4. Driven by the drive device 2, the middle plate 5 moves the upper mold 1 up and down. A foldable linkage mechanism 6 is connected between the upper plate 4 and the middle plate 5. When the drive device 2 moves the middle plate 5, the linkage mechanism 6 acts as a buffer and prevents it from falling, effectively ensuring the safe operation of the equipment.

[0022] like Figure 1 , 2 As shown in Figures 5 and 6, the drum unit 20 includes a frame 7 supported on the ground, a drum machine 8 rotatably mounted on the frame 7, and a drive motor 9 for driving the drum machine 8 to rotate. The drum machine 8 has a centerline X1 extending in the left-right direction and multiple mounting stations 81 arranged sequentially around the centerline X1. Each mounting station 81 is detachably equipped with a lower mold 11. The drum unit 20 has a hot pressing station 201 located directly below the upper mold 1 and a unloading station 202 located directly below the drum machine 8. When the drive motor 9 drives the drum machine 8 to rotate around the centerline X1, the multiple lower molds 11 rotate with the drum machine 8 around the centerline X1 and enter the hot pressing station 201 in sequence. When the upper mold 1 descends to the pressing position, the lower mold 11 in the hot pressing station 201 presses against the upper mold 1 to perform hot pressing shaping on the product on the lower mold 11.

[0023] The bottom of the multiple guide columns 3 of the hot press 10 is fixedly installed on the top of the frame 7 to reduce the floor space of the hot press shaping equipment 100.

[0024] In this embodiment, the drum machine 8 has six mounting stations 81, meaning that six lower molds 11 are mounted on the drum machine 8. The drive motor 9, which is connected to the drum machine 8, is a servo motor. The servo motor is highly responsive and can drive the drum machine 8 to rotate in a rhythmic manner according to control commands. In other embodiments, the drive motor can also be a stepper motor. Stepper motors drive the drum machine to rotate in a rhythmic manner and are low in cost.

[0025] like Figure 5-7 As shown, during the pressing process between the upper mold 1 and the lower mold 11 in the hot pressing station 201, a positioning structure is provided between the frame 7 and the drum machine 8 to ensure the accuracy and stability of the pressing.

[0026] The positioning structure includes a pair of positioning cylinders 12 mounted on the top of the frame 7 and multiple pairs of positioning components 13 mounted on the drum machine 8. The pair of positioning cylinders 12 are located on the left and right sides of the drum machine 8, respectively. Each installation station 81 is equipped with a limit component 13 on the left and right sides, and each limit component 13 includes a pair of oppositely arranged limit blocks 131. A limit groove 132 is formed between the pair of limit blocks 131 for the end of the air rod of the positioning cylinder 12 to be inserted. When one of the lower molds 11 enters the hot pressing station 201, the air rods of the pair of positioning cylinders 12 extend and are respectively inserted into the limit groove 132 corresponding to the installation station 81 where the lower mold 11 is installed, so as to prevent the drum machine 8 from rotating during the pressing process of the upper mold 1 and the lower mold 11, thus ensuring the hot pressing efficiency and shaping effect.

[0027] When the lower mold 11 rotates to the unloading station 202 with the product, under the influence of gravity and the blowing action of the lower mold 11, the product falls downward from the corresponding lower mold 11 at the unloading station 202.

[0028] like Figure 2 , 8 As shown, the elevator 30 includes a receiving end 14 located below the unloading station 202 and an output end 15 located behind the drum device 20, with the output end 15 located above the receiving end 14. The elevator 30 also includes a support frame 16, a conveyor belt 17 rotatably mounted on the support frame 16, and a partition assembly 18 mounted on the support frame 16. The partition assembly 18 is located above the conveyor belt 17 and includes a plurality of partition plates 181 spaced apart in a left-right direction. Two adjacent partition plates 181 and the conveyor belt 17 define a conveying channel 301. In this embodiment, the partition assembly 18 and the conveyor belt 17 define two left-right opposing conveying channels 301.

[0029] The receiving end 14 receives the product 200 falling from the unloading station 202 at the unloading station 202. The conveyor belt 17 reciprocates from the receiving end 14 to the output end 15, transporting the product 200 received from the unloading station 202. The elevator 30 eliminates the height difference between the unloading station 202 and the sorting machine 40, transporting the product 200 from the lower unloading station 202 upwards to the rear sorting machine 40. On the other hand, it arranges and transports the products sequentially in the longitudinal direction through two conveying channels 301, facilitating the subsequent sorting of the products by the sorting machine 40.

[0030] like Figure 1 , 2As shown in Figures 8 and 9, the feeder 40 is located behind the output end 15 and is used to receive the products 200 transported by each conveyor channel 301 at the output end 15. The feeder 40 includes a stacking platform 19 and a pushing mechanism 21 located at the front end of the stacking platform 19. The pushing mechanism 21 is configured to transfer the products 200 output from each conveyor channel 301 to the stacking platform 19.

[0031] The pushing mechanism 21 includes at least one rotating pusher plate 211, and the stacking platform 19 has the same number of stacking stations 191 as the conveying channel 301. The two stacking stations 191 are arranged opposite each other, and the rotating pusher plate 211 is arranged between the output end 15 and the stacking platform 19.

[0032] like Figure 10 , 11 As shown, the feeding mechanism 21 also includes a rotating shaft 212 extending in the left-right direction and a rotary cylinder 213 tractively connected to the rotating shaft 212. At least one rotary pusher plate 211 is mounted on the rotating shaft 212 and configured to rotate with the rotating shaft 212. The rotary cylinder 213 drives the rotating shaft 212 to rotate about its own axis, causing the rotary pusher plate 211 mounted on the rotating shaft 212 to rotate back and forth between a first position near the output end and a second position near the two stacking stations.

[0033] like Figure 9-11 As shown, the front end of the stacking platform 19 is equipped with multiple backing plates 214 spaced apart in the left-right direction, all of which are perpendicular to the rotating shaft 212. A pair of backing plates 214 is configured between each stacking station 191 and its corresponding conveyor channel 301. In the left-right direction, the distance between the pair of backing plates 214 is the same as the width of the corresponding conveyor channel 301. During the rotation of the rotating push plate 211 from the first position to the second position, the products 200 on the rotating push plate 211 are precisely fed into the corresponding stacking station 191 along the pair of backing plates 214. The pair of backing plates 214 configured in front of each stacking station 191 effectively prevents products from falling off the rotating push plate 211.

[0034] Each stacking station 191 is equipped with a brush, which is positioned at least on the left and right sides of the stacking station 191, all facing inwards. The brush bristles are flexible, providing a cushioning effect for the products 200 entering the stacking station 191, effectively reducing direct collisions between the products and the stacking station 191, and preventing surface damage or deformation of the products. Simultaneously, the flexible bristles are suitable for products of different sizes and shapes, ensuring that the products are stably placed and arranged sequentially during the stacking process, effectively enhancing positioning accuracy. The brushes work in conjunction with the corresponding rotating push plate 211 and a pair of backing plates 214 to improve stacking efficiency and effect, aligning the products longitudinally for easy subsequent manual transfer.

[0035] like Figure 5 , 6 As shown, the rotary drum hot pressing shaping equipment 100 also includes a control device, which is connected to the hot press 10, the rotary drum equipment 20, the elevator 30, and the feeder 40 to control the operation of each device. The control device also includes a control panel 22 mounted on the frame 7. Operators can obtain the operating parameters of each device through the control panel 22, and can also input commands through the control panel 22 to control the operation of each device.

[0036] like Figure 1 , 2 As shown, the working principle of this application is as follows: the rotary drum machine 8 rotates the lower mold 11 containing the product to be shaped to the hot pressing station 201. A pair of positioning cylinders 12 lock the position of the rotary drum machine 8. The upper mold 1 of the hot press machine 10 descends from the rising position to the pressing position to press the product on the lower mold 11 of the hot pressing station 201 for hot pressing shaping. At the same time, in the rotation direction of the rotary drum machine 8, the operator can add products to be shaped in the lower mold 11 upstream of the hot pressing station 201 to wait for the rotary drum machine 8 to rotate one installation station 81 for the next hot pressing shaping. When the lower mold 11 downstream of the hot pressing station 201 rotates to the unloading station 202, air is blown. The shaped product falls from the lower mold 11 to the receiving end 14 of the elevator 30 below. The product that falls on the receiving end 14 is conveyed by the conveyor belt 17 and moves backward and upward along the corresponding conveyor channel 301. At the output end 15, it falls onto the corresponding rotating push plate 211 along the corresponding pair of back plates 214. The rotating push plate 211 is driven by the rotating cylinder 213 to rotate from the first position to the second position, sending the product into the corresponding stacking station 191. The operator takes away the stacked product in the stacking station 191.

[0037] The rotary drum equipment of this application, in conjunction with a hot press, allows operators to feed materials onto the lower mold and automatically unload shaped products from the lower mold while hot pressing and shaping, effectively saving time and labor. The elevator and the material sorting machine work together to receive the products unloaded from the rotary drum equipment in a timely manner and stack the products longitudinally for easy subsequent manual transfer.

[0038] 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.
