[0019] Embodiment 1

[0020] Figure 1 The utility model is shown as a front structural schematic diagram of the paper-plastic tableware forming machine with the feeding mechanism hidden. Figure 2 The top view of the paper-plastic tableware forming machine of the utility model is shown. Figure 1 and Figure 2 A paper-plastic tableware forming machine includes a pulp suction mold 3, a bidirectional moving mechanism 5 and a forming mechanism 4. The pulp suction mold 3 is arranged upward, and the bottom surface is connected to a telescopic component 31. The telescopic component 31 can be a telescopic structure known in various types of technologies. For example, the telescopic component 31 can be a cylinder, which extends to push the pulp suction mold 3 to fit the first upper mold 41 or the second upper mold 42. Or the telescopic component 31 retracts to drive the pulp suction mold 3 away from the first upper mold 41 or the second upper mold 42 until the pulp suction mold is immersed in the pulp pool 2 to replenish the pulp in the pulp tank (not marked in the figure) of the pulp suction mold.

[0021] The bidirectional moving mechanism 5 includes a first moving component 51 and a second moving component 52 which are arranged in parallel above the slurry suction mold 3. The molding mechanism 4 includes a first upper mold 41, a second upper mold 42 and at least two molding lower molds 43. The molding lower mold 43 is a heating lower mold. The first upper mold 41 and the second upper mold 42 are respectively connected to the first moving component 51 and the second moving component 52. The first upper mold 41 and the second upper mold 42 are allowed to move independently of each other, and can be respectively attached to the slurry suction mold 3 to dehydrate the pulp. When the first upper mold 41 and the slurry suction mold 3 are dehydrated and the drying process is carried out, the second upper mold 42 can be seamlessly connected with the slurry suction mold to carry out the dehydration process, which greatly improves the utilization rate and production efficiency of the equipment.

[0022] The molding lower mold 43 is arranged below the bidirectional moving mechanism 5. The first upper mold 41 and the second upper mold 42 are connected with the telescopic assembly 31. When the first upper mold 41 or the second upper mold 42 moves above the molding lower mold 43, the telescopic assembly 31 drives the first upper mold 41 or the second upper mold 42 downward to fit the molding lower mold 43 to perform the drying and shaping process. Alternatively, the molding lower mold 43 is connected with the telescopic assembly 31. When the first upper mold 41 or the second upper mold 42 moves above the molding lower mold 43, the telescopic assembly 31 drives the molding lower mold 43 upward to fit the first upper mold 41 or the second upper mold 42 to perform the drying and shaping process.

[0023] The specific structures of the forming mechanism 4, the bidirectional moving mechanism 5 and the unloading mechanism 6 are described below:

[0024] Figure 3 The three-dimensional structure diagram of the paper-plastic tableware forming machine of the utility model is shown. Figure 1 , Figure 2 and Figure 3 , air holes 431 are respectively provided on the first upper mold 41, the second upper mold 42 and the forming lower mold 43. After the pulp is dehydrated, the slurry suction mold 3 moves downward, and the air holes 431 of the first upper mold 41 or the second upper mold 42 that completes the pulp dehydration process generate negative pressure to absorb the dehydrated pulp. After the pulp is dried, the air holes 431 on the forming lower mold 43 that completes the arch rod process generate negative pressure to absorb the pulp that completes the arch rod shaping process, which is convenient for subsequent unloading. The air holes 431 at various locations cooperate with each other to automatically transport materials.

[0025] The first moving assembly 51 is a first lead screw, and the second moving assembly 52 is a second lead screw. The first lead screw and the second lead screw are respectively connected to a driving motor (not shown in the figure). The first upper mold 41 is driven by the first lead screw, and the second upper mold 42 is driven by the second lead screw, so that the movement of the first upper mold 41 and the second upper mold 42 can be independently controlled. The transmission efficiency, accuracy and load capacity of the lead screw drive are very good, and it has a strong self-locking performance. In special circumstances such as power failure, it can also maintain the position unchanged and is not easy to slide or retreat. Enhance the safety of the equipment. The unloading mechanism 6 includes a material tray 62 and a slide rail 61 connected to the material tray 62. Drive the material tray 62 to slide along the slide rail 61 to perform the unloading action.

[0026] The specific structure of the pulp pool 2 and the pulp suction mold 3 is described below:

[0027] Please refer to Figure 1 , and also includes a pulp pool 2, in which a pulp suction mold 3 is arranged. Correspondingly, a telescopic component 31 connected to the pulp suction mold 3 is also arranged in the pulp pool 2. The pulp suction mold 3 is driven to immerse in the pulp pool 2 or to perform a dewatering process through the telescopic component 31. The telescopic component 31 is extended and retracted and the pulp suction mold 3 moves in the pulp pool 2, which also stirs the pulp in the pulp pool 2, so that the fibers of the pulp are evenly distributed, thereby ensuring product quality.

[0028] A pulp groove is provided above the pulp suction mold 3, and the bottom surface of the pulp groove is in contact with the lower surface of the first upper mold 41 and the second upper mold 42. The pulp groove contains pulp, and when the pulp groove is immersed in the pulp pool 2, the pulp in the pulp groove is automatically replenished, and the pulp is subsequently dehydrated.

[0029] The specific structure of the gas source and the frame 1 is described below:

[0030] Please refer to Figure 3 , and also includes an air source (not shown in the figure), which is connected to the molding mechanism 4 through an air pipeline 7. The air source is integrated into the device to avoid external air supply equipment, save cumbersome connection steps and cable layout, and facilitate the use of the device in different places. It also includes a frame 1, and the molding mechanism 4 is slidably connected to the frame 1 to increase the stability of the molding mechanism 4 during movement.

[0031] Embodiment 2

[0032] Based on the first embodiment, the second embodiment discloses a paper-plastic tableware forming machine in which there is a horizontal height difference between the first upper mold 41 and the second upper mold 42. Specifically, the end of the first upper mold 41 away from the second upper mold 42 is connected to the first moving assembly 51, and the end of the second upper mold 42 away from the first upper mold 41 is connected to the second moving assembly 52. ​​The first upper mold 41 and the second upper mold 42 are slidably connected to the frame 1 to ensure the stability and load of the first upper mold 41 and the second upper mold 42. The first upper mold 41 and the second upper mold 42 are arranged up and down to increase the range of travel that does not interfere with each other during the movement of the first upper mold 41 and the second upper mold 42, thereby increasing the flexibility of the equipment. For example, when the first upper mold 41 is above the second upper mold 42, the first upper mold 41 is at the pulp dewatering station. If the pulp dewatering action of the second upper mold 42 and the pulp suction mold is to be performed, the first upper mold 41 does not need to move its position, and the second upper mold 42 can be directly moved to the pulp dewatering station.

[0033] Embodiment 3

[0034] Based on the first and second embodiments, the third embodiment discloses a paper-plastic tableware forming machine in which a slider 53 is respectively provided between the first upper mold 41 and the first moving assembly 51, and between the second upper mold 42 and the second moving assembly 52. ​​Specifically, the slider 53 is connected to the first moving assembly 51 and the second moving assembly 52 and is driven, and the first upper mold 41 and the second upper mold 42 are slidably connected to the bottom of the slider 53. When adjusting and maintaining the equipment, the position of the slider 53 where the first upper mold 41 and the second upper mold 42 are slidably connected can be directly adjusted without adjusting the bidirectional motion mechanism, so as to facilitate equipment calibration.

[0035] The specific working process of the utility model is as follows:

[0036] For example, the molding lower mold 43 is connected to the telescopic assembly 31 , and the first upper mold 41 and the second upper mold 42 are not connected to the telescopic assembly 31 .

[0037] In the first action, the first moving component 51 drives the first upper mold 41 to move to the top of the pulp pool 2, and the telescopic component 31 drives the pulp suction mold 3 to extend, and the pulp suction mold extends from the pulp pool 2 and fits the first upper mold 41 to perform the pulp dewatering action. After the dewatering is completed, the air source controls the air holes 431 on the first upper mold 41 to generate negative pressure to absorb the dehydrated pulp. The telescopic component 31 drives the pulp suction mold 3 to retract until the pulp suction mold is immersed in the pulp pool 2. The first moving component 51 drives the first upper mold 41 to move to the top of the forming lower mold 43. The forming lower mold 43 is driven upward by the telescopic component 31 until the forming lower mold 43 fits the first upper mold 41 to perform the drying and shaping action. After the drying and shaping is completed, the air source controls the air holes 431 on the forming lower mold 43 to generate negative pressure to absorb the dried and shaped pulp. The forming lower mold 43 is driven by the telescopic assembly 31 connected thereto to move down to the unloading station, and the first upper mold 41 waits for the second upper mold 42 to complete the pulp dehydration action and leave the pulp dehydration station, and then the first upper mold 41 moves to the pulp dehydration station to perform the pulp dehydration action. The material tray 62 moves along the slide rail 61 to the unloading station, clamps the material and moves out of the unloading station along the slide rail 61, and the first action is completed.

[0038] In the second action, after the first upper mold 41 moves out of the pulp dewatering station, the second moving assembly 52 drives the second upper mold 42 to move to the pulp dewatering station above the pulp pool 2. The telescopic assembly 31 drives the pulp suction mold 3 to extend, and the pulp suction mold extends from the pulp pool 2 and fits the second upper mold 42 to perform the pulp dewatering action. After the dewatering is completed, the air source controls the air holes 431 on the second upper mold 42 to generate negative pressure to absorb the dewatered pulp. The telescopic assembly 31 drives the pulp suction mold 3 to retract until the pulp suction mold is immersed in the pulp pool 2. The second moving assembly 52 drives the second upper mold 42 to move to the top of a forming lower mold 43. The forming lower mold 43 is driven upward by the telescopic assembly 31 until the forming lower mold 43 fits the second upper mold 42 to perform the drying and shaping action. After the drying and shaping is completed, the air source controls the air holes 431 on the forming lower mold 43 to generate negative pressure to absorb the dried and shaped pulp. The forming lower mold 43 is driven by the telescopic assembly 31 connected thereto to move down to the unloading station, and the second upper mold 42 waits for the first upper mold 41 to complete the pulp dehydration action and leave the pulp dehydration station, and then the second upper mold 42 moves to the pulp dehydration station to perform the pulp dehydration action. The material tray 62 moves along the slide rail 61 to the unloading station, clamps the material and moves out of the unloading station along the slide rail 61, and the second action is completed.

[0039] The first action and the second action are performed alternately to repeat the forming process.

[0040] It can be seen that in the above-mentioned paper-plastic tableware forming machine, the first upper mold 41 and the second upper mold 42 move independently of each other and can be respectively attached to the pulp absorption mold 3 to dehydrate the pulp. When the first upper mold 41 and the pulp absorption mold 3 are dehydrated and the drying process is performed, the second upper mold 42 can be seamlessly connected with the pulp absorption mold to perform the dehydration process, which greatly improves the utilization rate and production efficiency of the equipment.

[0041] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
