DETAILED DESCRIPTION

[0017] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many 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 the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0018] An embodiment of the present application provides a rotary drum hot pressing and shaping equipment, which is used to continuously perform hot pressing and trimming on irregular products after sun drying, and can automatically complete the hot pressing and shaping, material storage and material sorting of the products, effectively reducing labor, lowering operating difficulty, 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 sorting 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 driving device 2 that is transmission-connected to the upper mold 1. The upper mold 1 has an ascending position in the up and down directions and a descending position below the ascending position. The driving device 2 is used to drive the upper mold 1 to move back and forth between the ascending position and the descending position.

[0021] The hot press 10 also includes a plurality of guide posts 3 extending in the vertical direction, an upper plate 4 mounted on top of the guide posts 3, and a middle plate 5 mounted vertically and movably on the guide posts 3. The upper mold 1 is mounted on the middle plate 5, and the drive device 2 is mounted on the upper plate 4. The middle plate 5 drives the upper mold 1 to move up and down under the drive device 2. A foldable connecting rod mechanism 6 is connected between the upper plate 4 and the middle plate 5. When the drive device 2 drives the middle plate 5 to move, the connecting rod mechanism 6 acts as a buffer and prevents the middle plate 5 from falling, effectively ensuring the safe operation of the equipment.

[0022] like Figure 1 、 2 As shown in Figures 5 and 6, the drum device 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 an axis X1 extending in the left-right direction and a plurality of mounting stations 81 arranged in sequence along the circumference of the axis X1. Each mounting station 81 is detachably mounted with a lower mold 11. The drum device 20 has a hot pressing station 201 located directly below the upper mold 1 and a blanking station 202 located directly below the drum machine 8. When the drive motor 9 drives the drum machine 8 to rotate around the axis X1, the plurality of lower molds 11 rotate along with the drum machine 8 around the axis X1 and enter the hot pressing station 201 in sequence. When the upper mold 1 descends to the pressing position, the lower molds 11 in the hot pressing station 201 are pressed together with the upper mold 1 to perform hot pressing and shaping on the product on the lower mold 11.

[0023] The bottoms of the multiple guide pillars 3 of the hot pressing machine 10 are fixedly mounted on the top of the frame 7 to reduce the floor space occupied by the hot pressing shaping device 100 .

[0024] In the embodiment of the present application, the drum machine 8 has six mounting stations 81, i.e., six lower molds 11 are mounted on the drum machine 8. The drive motor 9, which is in transmission connection with the drum machine 8, is a servo motor. The servo motor is highly responsive and can drive the drum machine 8 to rotate rhythmically according to control commands. In other embodiments, the drive motor can also be a stepper motor, which can drive the drum machine to rotate rhythmically and is low-cost.

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

[0026] The positioning structure includes a pair of positioning cylinders 12 installed on the top of the frame 7 and multiple pairs of positioning assemblies 13 installed on the drum machine 8. A pair of positioning cylinders 12 are respectively located on the left and right sides of the drum machine 8. A limiting assembly 13 is respectively configured on the left and right sides of each installation station 81. Each limiting assembly 13 includes a pair of relatively set limiting blocks 131. A limiting groove 132 is formed between the pair of limiting blocks 131 for the end of the gas rod of the positioning cylinder 12 to be inserted. When one of the lower molds 11 enters the hot pressing station 201, the gas rods of the pair of positioning cylinders 12 extend and are respectively inserted into the limiting grooves 132 corresponding to the installation station 81 where the lower mold 11 is installed, thereby preventing the drum machine 8 from rotating during the pressing process of the upper mold 1 and the lower mold 11, thereby ensuring the hot pressing efficiency and shaping effect.

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

[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 on the rear side of 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 the left-right direction. Two adjacent partition plates 181 and the conveyor belt 17 define a conveying channel 301. In the embodiment of the present application, the partition assembly 18 and the conveyor belt 17 define two conveying channels 301 that are opposite to each other.

[0029] The receiving end 14 receives the products 200 dropped from the unloading station 202 at the unloading station 202, and the conveyor belt 17 reciprocates and transports the products 200 received from the unloading station 202 from the receiving end 14 to the output end 15. The elevator 30, on the one hand, eliminates the height difference between the unloading station 202 and the material sorter 40, and transports the products 200 from the lower unloading station 202 upward to the material sorter 40 at the rear. On the other hand, the two conveying channels 301 arrange the products in sequence in the longitudinal direction for transportation, facilitating subsequent product sorting by the material sorter 40.

[0030] like Figure 1 、 2As shown in Figures 8 and 9, the material sorter 40 is located at the rear side of the output end 15 and is used to receive the products 200 transported by each conveying channel 301 at the output end 15. The material sorter 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 by each conveying channel 301 to the stacking platform 19.

[0031] The pushing mechanism 21 includes at least one rotating push plate 211 . The coding platform 19 has coding stations 191 whose number is the same as the conveying channels 301 . The two coding stations 191 are arranged opposite to each other on the left and right. The rotating push plate 211 is arranged between the output end 15 and the coding platform 19 .

[0032] like Figure 10 、 11 As shown, the pushing mechanism 21 further includes a rotating shaft 212 extending in the left-right direction and a rotating cylinder 213 drivingly connected to the rotating shaft 212. At least one rotating push plate 211 is mounted on the rotating shaft 212 and is configured to rotate with the rotating shaft 212. The rotating cylinder 213 is used to drive the rotating shaft 212 to rotate about its own axis, so that the rotating push plate 211 mounted on the rotating shaft 212 rotates 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 support plates 214 spaced apart in the left-right direction. Each support plate 214 is perpendicular to the rotating shaft 212. A pair of support plates 214 is positioned between each stacking station 191 and the corresponding conveying channel 301. The distance between the support plates 214 in the left-right direction corresponds to the width of the corresponding conveying channel 301. As the rotating push plate 211 rotates from the first position to the second position, the products 200 on the rotating push plate 211 are precisely fed along the pair of support plates 214 into the corresponding stacking station 191. The pair of support plates 214 positioned 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, located at least on the left and right sides of the station 191, and facing inward. The flexible bristles of the brush provide a cushioning effect on 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. Furthermore, the flexible bristles accommodate products of varying sizes and shapes, ensuring stable placement and sequential alignment during the stacking process, effectively enhancing positioning accuracy. The brushes work in conjunction with the corresponding rotating push plates 211 and a pair of support plates 214 to improve stacking efficiency and effectiveness, aligning the products longitudinally for easy manual transfer.

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

[0036] like Figure 1 、 2 As shown, the working principle of the present 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 locks the position of the rotary drum machine 8, and the upper mold 1 of the hot pressing machine 10 descends from the ascending position to the descending position to press the product on the lower mold 11 with 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 the product 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 to an installation station 81 for the next hot pressing shaping; and the lower mold 11 downstream of the hot pressing station 201 is blown when it is rotated to the unloading station 202, and the shaped product falls from the lower mold 11 to the receiving end 14 of the elevator 30 below. The products dropped on the receiving end 14 move backward and upward along the corresponding conveying channel 301 under the conveyance of the conveyor belt 17, and fall on the corresponding rotating push plate 211 along the corresponding pair of support plates 214 at the output end 15. The rotating push plate 211 is driven by the rotating cylinder 213 to rotate from the first position to the second position, and the products are sent to the corresponding coding station 191. The operator takes away the coded products in the coding station 191.

[0037] The rotary drum equipment of the present application cooperates with the hot press, and can allow the operator to discharge the material onto the lower mold and automatically unload the shaped product from the lower mold during hot pressing and shaping, effectively saving time and labor; the elevator and the material sorting machine cooperate to promptly receive the products unloaded by the rotary drum equipment, and stack the products in the longitudinal direction to facilitate subsequent manual transportation.

Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes.
