[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1 Reference Figures 1-10 This is the first embodiment of the present invention, which provides a rapid demolding device for pulp molding. The rapid demolding device for pulp molding includes a main body component 1 and a clamping component 2. The two work together to automatically remove the cup from the mold after the cup film is formed, effectively reducing the demolding time. The main component 1 includes a molding machine 11, a template 12 is provided on the molding machine 11, and a blanking plate 13 is provided below the template 12.

[0031] The molding machine 11 is used to perform molding operations on products such as cups. Through relevant processes, the raw materials are processed into products of a specific shape. The template 12 provides the corresponding shape and structural foundation for the molding of cups and assists in shaping the outline of the product. The blanking plate 13 is set below the template 12 to receive the cups that are initially formed from the template 12, which facilitates the subsequent processes.

[0032] The clamping assembly 2 is disposed on the unloading plate 13 and includes a clamping member 21. The clamping member 21 includes a movable frame 211. The movable frame 211 is hinged to the bottom of the unloading plate 13. A gripper 212 is provided on the top of the movable frame 211, and a guide bar 213 is provided below the gripper 212.

[0033] After the cup is molded, the template 12 is moved to be directly above the unloading plate 13. Then, the moving frame 211 moves to raise the unloading plate 13. At this time, the gripper 212 can hold the cup on the template 12. Then the unloading plate 13 is lowered. When the unloading plate 13 is lowered, the guide bar 213 moves to release the gripper 212 from the cup. Then the unloading plate 13 is lowered to the designated position and tilted so that the cup on the unloading plate 13 can slide into the collection frame on one side of the molding machine 11.

[0034] Example 2 Reference Figures 2-10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the clamping assembly 2 also includes a drive component 22, which includes a cylinder 221, and the cylinder 221 is fixed to the bottom of the movable frame 211.

[0036] The cylinder 221 is fixed to one side of the molding machine 11. By starting the cylinder 221, the moving frame 211 can be moved.

[0037] Specifically, a sliding frame 222 is fixed to the bottom of the feeding plate 13, and an extrusion rod 223 is slidably connected to the bottom of the sliding frame 222. An electric push rod 224 is fixed to the bottom of the extrusion rod 223, and the electric push rod 224 is fixed to the top of the movable frame 211.

[0038] When it is necessary to tilt the feeding plate 13, the electric push rod 224 is activated to extend and retract it. At this time, the electric push rod 224 can drive the extrusion rod 223 to extrude the sliding frame 222, thereby tilting the feeding plate 13 and guiding the cup on it into the collection frame on one side of the molding machine 11.

[0039] Specifically, a positioning plate 225 is hinged to the bottom of the gripper 212, and a positioning cover 226 is fixed to the bottom of the positioning plate 225. The positioning cover 226 is fixed to the top of the unloading plate 13.

[0040] The positioning disk 225 can support the gripper 212 and prevent the gripper 212 from shifting. The positioning cover 226 is used to support the positioning disk 225.

[0041] Specifically, a downward pressure rod 227 is hinged to one side of the gripper 212, and a connecting plate 228 is fixed to the bottom of the downward pressure rod 227.

[0042] When the feeding plate 13 is raised, the movable rod 229 can be moved to the bottom of the template 12. Then the feeding plate 13 continues to rise, which can squeeze the movable rod 229. The movable rod 229 drives the connecting plate 228 to move. The movement of the connecting plate 228 drives the downward pressing rod 227 to move, which can drive the gripper 212 to clamp the cup. Then the feeding plate 13 descends, separating the cup from the template 12 and releasing the squeezing of the movable rod 229. At this time, the return of the connecting plate 228 to its original position can release the gripper 212 from clamping the cup. Then the feeding plate 13 descends and tilts, so that the cup on it can slide into the collection frame.

[0043] Example 3 Reference Figures 1-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0044] Specifically, a movable rod 229 is fixed to the top of the connecting plate 228, and a first spring 2291 is fixed to the top of the connecting plate 228. One end of the first spring 2291 is fixed to the inner wall of the positioning plate 225.

[0045] When the movable rod 229 moves, it drives the connecting plate 228 to move, causing the gripper 212 to clamp the cup. At this time, a squeezing force can be applied to the first spring 2291. The rebound force of the first spring 2291 can drive the connecting plate 228 back to its original position, thereby releasing the gripper 212.

[0046] Specifically, the clamping assembly 2 also includes a movable component 23, which includes a connecting frame 231, which is disposed on one side of the guide bar 213.

[0047] Two grooves corresponding to the guide bar 213 are respectively provided on the connecting frame 231. One groove has an inclined groove. One end of the guide bar 213 is set as an inclined surface. When the connecting plate 228 descends, it can slide on the inclined groove. At this time, the inclined groove can limit the guide bar 213 in one direction, preventing the connecting plate 228 from rising due to the rebound force of the first spring 2291 and causing the gripper 212 to release. Then, after the gripper 212 clamps the cup, the guide bar 213 will move to the other groove through the guide of the connecting frame 231. It will stay briefly in the other groove, allowing the gripper 212 to remove the cup from the template 12. Then the guide bar 213 slides in the other smooth groove, so that the connecting plate 228 can rise due to the rebound force of the first spring 2291, thereby allowing the gripper 212 to release the cup.

[0048] Specifically, a stop 232 is hinged to the inner wall of the connecting frame 231, and a torsion spring 233 is fixed to one side of the stop 232. One end of the torsion spring 233 is fixed to the inner wall of the connecting frame 231.

[0049] When the guide bar 213 moves into another smooth groove, it will move to the side of the stop 232. Then, the torsion spring 233 can block the guide bar 213. After a certain period of time, the force of the first spring 2291 rebounding will overcome the force of the torsion spring 233 and open the stop 232, allowing the guide bar 213 to return to its original position. After the guide bar 213 separates from the stop 232, the force of the torsion spring 233 will drive the stop 232 to close for the next use. After the guide bar 213 moves to one end of the smooth groove, when it descends again, the guide frame 231 can guide it to slide into the groove with the inclined groove.

[0050] Specifically, a support box 234 is slidably connected to one side of the guide bar 213, and an insert rod 2391 is fixed inside the support box 234. A second spring 235 is fixed to one side of the guide bar 213, and one end of the second spring 235 is fixed to the inner wall of the support box 234.

[0051] When the guide bar 213 moves into the groove with the inclined groove, it can apply a pulling force to the second spring 235. When the guide bar 213 moves into the groove with the inclined groove, the rebound force of the second spring 235 can move the guide bar 213 into the smooth groove. When the guide bar 213 moves, it can move on the insertion rod 2391, thereby supporting the guide bar 213. The support box 234 is used to support the insertion rod 2391.

[0052] Specifically, a connecting post 236 is fixed on one side of the support box 234, a pressure plate 237 is sleeved on the outside of the connecting post 236, a third spring 238 is fixed on one side of the pressure plate 237, and a positioning sleeve 239 is movably connected to the outside of the connecting post 236, and the positioning sleeve 239 is fixed to one side of the connecting plate 228.

[0053] When the guide bar 213 slides on one side of the inclined groove, the inclined groove squeezes the guide bar 213. At this time, it can drive the support box 234 to move. The movement of the support box 234 drives the connecting column 236 to move. The movement of the connecting column 236 drives the pressure plate 237 to apply a squeezing force to the third spring 238. When the guide bar 213 moves to the next inclined groove, the rebound force of the third spring 238 can drive the guide bar 213 to engage with the next inclined groove. By repeating this process, the guide bar 213 can be unidirectionally limited. The third spring 238 is fixed to the inner wall of the positioning sleeve 239. The positioning sleeve 239 can support the third spring 238 and prevent the third spring 238 from shifting.

[0054] In use, after the molding machine 11 completes the cup molding, the template 12 moves the molded cup directly above the unloading plate 13. At this time, the cylinder 221 is activated to push the moving frame 211 to rotate. The moving frame 211 drives the unloading plate 13 to rise. During the rise of the unloading plate 13, the movable rod 229 first contacts the bottom of the template 12 and is squeezed, which drives the connecting plate 228 to compress the first spring 2291 and move it down. The connecting plate 228 drives the pressure rod 227 to rotate. The pressure rod 227 pushes the gripper 212 to rotate along the positioning plate 225. The gripper 212 can then clamp the cup, realizing automatic clamping without manual operation and shortening the demolding preparation time.

[0055] Then the unloading plate 13 descends, and the gripper 212 causes the cup to separate from the template 12, completing the demolding. Subsequently, the cylinder 221 drives the moving frame 211 to reset, the unloading plate 13 descends, and the guide bar 213 descends with the unloading plate 13, sliding along the inclined groove of the connecting frame 231. The inclined groove compresses the guide bar 213, causing the support box 234 to compress the second spring 235. At the same time, the connecting column 236 drives the pressure plate 237 to compress the third spring 238, and the guide bar 213 moves to the connecting frame. When the cup moves to the other slide, the guide bar 213 is briefly blocked by the stop gate 232 under the action of the torsion spring 233 to ensure that the cup is stably removed from the template 12. When the rebound force of the first spring 2291 overcomes the elastic force of the torsion spring 233, the stop gate 232 can be opened. At this time, the guide bar 213 slides along the smooth slide. The rebound force of the first spring 2291 drives the connecting plate 228 and the lowering rod 227 to reset, and the gripper 212 can release the cup, and the cup falls onto the feed plate 13.

[0056] Then, the electric push rod 224 is activated to drive the extrusion rod 223 to slide along the sliding frame 222. The extrusion rod 223 extrudes the sliding frame 222, causing the feeding plate 13 to tilt. The cup slides down the feeding plate 13 to the collection frame, completing the automatic feeding. This reduces the demolding time, fits the efficient production rhythm, improves the overall production efficiency, and promotes the smooth operation of the production process.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
