Description

Technical Field

[0001] This utility model relates to the field of pulp injection molding, and in particular to an online forming device for pulp molding packaging. Background Technology

[0002] The pulp molding packaging online forming device is an automated equipment that uses waste paper, sugarcane pulp, and other raw materials to directly form environmentally friendly packaging products through online dewatering, molding, and drying processes. It can produce food trays, electronic product cushioning pads, medical device packaging, etc. It has advantages such as degradability, customizability, high efficiency and energy saving, and is widely used to replace plastic products and promote the green circular economy.

[0003] Existing online pulp molding packaging equipment lacks a scraper sealing function. Without this function, frequent machine shutdowns for cleaning and continuous pulp overflow can lead to reduced production efficiency and material waste.

[0004] Therefore, given that the existing online pulp molding packaging forming devices lack a scraper sealing function, require frequent shutdowns for cleaning, and constantly overflow pulp, resulting in reduced production efficiency and material waste, there is an urgent need to design a new type of online pulp molding packaging forming device. Utility Model Content

[0005] To overcome the problems of existing online pulp molding packaging equipment lacking a scraper sealing function, requiring frequent shutdowns for cleaning, and constantly overflowing pulp, which leads to reduced production efficiency and material waste.

[0006] The technical solution of this utility model is as follows: an online forming device for pulp molding packaging, including a base; it also includes a lifting frame, a motor, a screw, a sliding plate, a limiting rod, and a gate. An installation plate is installed at the middle of the upper end of the base, and a pulp outlet is opened at the middle of the front end of the installation plate. The lifting frame is installed at the middle of the upper end of the installation plate. The motor is installed on the right side of the upper end of the lifting frame. The output end of the motor passes through the upper end of the lifting frame and is connected to the screw. The lower end of the screw is rotatably connected to the lower end of the inner part of the lifting frame. One end of the sliding plate is threadedly connected to the outer surface of the screw. A limiting rod is installed on the left side of the upper inner part of the lifting frame. The other end of the sliding plate is slidably connected to the limiting rod. A gate is installed at the front end of the screw.

[0007] Preferably, a motor is installed. When the motor runs, it drives the screw to rotate. When the screw rotates, it limits the rotation of the slide plate through the limit rod, thereby driving the slide plate to move. When the slide plate moves, it drives the gate to move. When the injection molding is completed, the motor is started by the external controller to lower the gate. Since the gate and the mounting plate are in close contact, the gate will cut off the filaments between the pulp outlet and the injection molded product during the descent process. The gate will stay in front of the pulp outlet until the next injection begins, so that no pulp will overflow from the pulp outlet. This achieves the purpose of preventing filaments and pulp overflow, and solves the problem that the existing pulp molding packaging online forming device lacks the scraper sealing function. Without the scraper sealing function, there may be problems such as the need to stop the machine frequently for cleaning and continuous pulp overflow, resulting in reduced production efficiency and material waste.

[0008] Preferably, a storage bin is installed on the upper rear side of the base, a pipe is installed at the front end of the storage bin, the front end of the pipe is connected to the rear end of the mounting plate, a funnel is installed at the upper end of the storage bin, and a second motor is installed at the middle of the rear end of the storage bin. The output end of the second motor passes through the rear end of the storage bin and is connected to a screw feed rod.

[0009] Preferably, a support plate is installed on the upper front side of the base, and a hydraulic rod is installed at the middle of the front end of the support plate. The telescopic end of the hydraulic rod passes through the front end of the support plate and is connected to a pressure plate.

[0010] Preferably, a mounting groove is provided at the middle of the rear end of the support plate, and a knob is rotatably connected at the middle of the upper end of the pressure plate. The lower end of the knob passes through the upper end of the pressure plate and is connected to a two-way screw rod. The outer surface of the two-way screw rod is threaded with upper and lower symmetrical clamping plates.

[0011] Preferably, a rocker arm is mounted on the upper end of the knob, and a handle is rotatably connected to the front end of the upper end of the rocker arm.

[0012] Preferably, connecting plates are installed on both the upper left and right sides of the mounting plate, and a light rod is installed at the front end of each of the two connecting plates. Slider blocks are installed on both the upper left and right sides of the pressure plate, and the sliders are slidably connected to the light rods.

[0013] Preferably, the upper end of the base is provided with a material drop groove on the front side of the mounting plate, and a material receiving frame is provided at the bottom of the material drop groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up motor one, when motor one is running, it drives the screw to generate rotational motion. During the rotation of the screw, the rotational freedom of the slide plate is rigidly constrained by the limit rod, thereby pushing the slide plate to perform linear displacement. When the slide plate moves, it synchronously pulls the guillotine to generate a corresponding stroke. When the injection molding process ends, the external controller triggers motor one to start, driving the guillotine to descend vertically. Because the guillotine and the mounting plate are in a plane-fitted state, the guillotine directly cuts off the residual filaments between the pulp outlet and the injection molded product during the downward movement. Then the guillotine continues to stay at the front end of the pulp outlet until the next injection molding cycle starts. By physically blocking the flow of pulp from the pulp outlet, the purpose of preventing filaments from sticking and pulp overflow is achieved. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment: an online pulp molding packaging forming device, including a base 1; it also includes a lifting frame 4, a motor 5, a screw 6, a sliding plate 7, a limiting rod 8, and a gate 9. An mounting plate 2 is installed at the middle of the upper end of the base 1, and a pulp outlet 3 is opened at the middle of the front end of the mounting plate 2. The lifting frame 4 is installed at the middle of the upper end of the mounting plate 2. The motor 5 is installed on the upper right side of the lifting frame 4. The output end of the motor 5 passes through the upper end of the lifting frame 4 and is connected to the screw 6. The lower end of the screw 6 is rotatably connected to the lower inner end of the lifting frame 4. One end of the sliding plate 7 is threadedly connected to the outer surface of the screw 6. A limiting rod is installed on the upper left side of the inner end of the lifting frame 4. 8. The other end of the slide plate 7 is slidably connected to the limit rod 8. A gate 9 is installed at the front end of the screw 6. By setting a motor 5, the screw 6 is rotated when the motor 5 is running. When the screw 6 rotates, the limit rod 8 restricts the rotation of the slide plate 7, thereby driving the slide plate 7 to move. When the slide plate 7 moves, it drives the gate 9 to move. When the injection molding is completed, the motor 5 is started by the external controller to lower the gate 9. Since the gate 9 is in contact with the mounting plate 2, the gate 9 will cut off the filaments between the pulp outlet 3 and the injection molded product during the descent process. Before the next injection molding starts, the gate 9 will stay in front of the pulp outlet 3 to prevent pulp from overflowing from the pulp outlet 3, thereby achieving the purpose of preventing filaments and pulp overflow.

[0024] Please see Figures 1-4In this embodiment, a storage chamber 10 is installed on the upper rear side of the base 1, and a pipe 11 is installed on the front end of the storage chamber 10. The front end of the pipe 11 is connected to the rear end of the mounting plate 2. A funnel 12 is installed on the upper end of the storage chamber 10, and a second motor 13 is installed at the middle of the rear end of the storage chamber 10. The output end of the second motor 13 passes through the rear end of the storage chamber 10 and is connected to a screw feeder 14. By setting up the storage chamber 10, the pulp enters the storage chamber 10 from the funnel 12 for storage. Then, by setting up the second motor 13, the second motor 13 drives the screw feeder 14 to rotate, thereby sending the pulp along the thread of the screw feeder 14 from the storage chamber 10 through the pipe 11 to the pulp outlet 3, thus achieving the purpose of pulp injection molding. A support plate 15 is installed on the upper front side of the base 1, and a hydraulic rod 16 is installed at the middle of the front end of the support plate 15. The telescopic end of the hydraulic rod 16 passes through the front end of the support plate 15 and is connected to a pressure plate 1. 7. By setting up a hydraulic rod 16, the hydraulic rod 16 drives the pressure plate 17 to move when it runs. When the pressure plate 17 moves, it will bring the mold and the mounting plate 2 into contact, thereby performing injection molding. This achieves the purpose of moving the mold. The support plate 15 has a mounting groove 18 at the middle of its rear end. The upper middle of the pressure plate 17 is rotatably connected to a knob 19. The lower end of the knob 19 passes through the upper end of the pressure plate 17 and is connected to a double-acting screw 20. The outer surface of the double-acting screw 20 is threaded with symmetrical clamping plates 21. By setting up the knob 19, turning the knob 19 drives the double-acting screw 20 to rotate. When the double-acting screw 20 rotates, it restricts the rotation of the clamping plates 21 through the mounting groove 18, thereby driving the two clamping plates 21 to move relative to each other. When the two clamping plates 21 are close together, the mold can be clamped and fixed. Conversely, when the two clamping plates 21 are separated, the mold can be replaced, thereby achieving the purpose of installing and replacing the mold.

[0025] Please see Figures 1-5In this embodiment, a rocker arm 22 is mounted on the upper end of the knob 19, and a handle 23 is rotatably connected to the front end of the upper end of the rocker arm 22. By setting the rocker arm 22, the torque applied to the knob 19 can be increased. By setting the handle 23, the operator can have a grip point when turning the rocker arm 22, thereby achieving the purpose of easily turning the knob 19. Connecting plates 24 are mounted on the left and right sides of the upper end of the mounting plate 2, and a smooth rod 25 is mounted on the front end of each of the two connecting plates 24. Slider 26 is mounted on the left and right sides of the upper end of the pressure plate 17. The slider 26 is slidably connected to the smooth rod 25. Block 26, since the slider 26 is connected to the pressure plate 17, moves the slider 26 together with the pressure plate 17 when it moves. The slider 26 is restricted by the light rod 25, so that the pressure plate 17 will not deviate during movement, thus achieving the purpose of assisting the pressure plate 17 to move linearly. The upper end of the base 1 is provided with a material drop groove 27 on the front side of the mounting plate 2. The bottom of the material drop groove 27 is provided with a receiving frame 28. By setting the material drop groove 27, the injection molded product can fall directly from the material drop groove 27 into the receiving frame 28, thereby reducing the workload of the workers.

[0026] During operation, by setting knob 19, the rocker arm 22 is used to rotate knob 19 to open the two clamping plates 21, then the mold is placed inside. Knob 19 is then rotated in the opposite direction to clamp the mold between the two clamping plates 21. Then, the hydraulic rod 16, in conjunction with the guide rod 25 and the slider 26, is activated to stably drive the pressure plate 17 to bring the mold and mounting plate 2 into contact. After completion, hot pulp is poured from funnel 12 into storage bin 10. Then, motor 13 drives the screw feed rod 14 to rotate, causing the threads on the screw feed rod 14 to... Hot pulp is fed to the pulp outlet 3, and then the hot pulp is fed into the mold through the pulp outlet 3. Then the external vacuum pump is started to vacuum the hot pulp inside the mold and form it. After completion, the hydraulic rod 16 drives the mold to move backward. At the same time, the motor 5 starts to lower the gate 9, cuts off the hanging wire between the pulp outlet 3 and the molded part, and stops in front of the pulp outlet 3 to physically isolate the pulp outlet 3 to prevent pulp from overflowing. It rises again during the next injection molding. With the assistance of the staff, the molded part is peeled off and enters the receiving frame 28 through the drop trough 27.

[0027] Through the above steps, by setting up motor 5, after motor 5 starts, it drives screw 6 to rotate axially. When screw 6 rotates, it forms a locking effect on the circumferential movement of slide plate 7 through limit rod 8, forcing slide plate 7 to move along a straight path. During the movement of slide plate 7, the linkage gate 9 moves synchronously. When the injection cycle is completed, the external controller activates motor 5 to run, forcing gate 9 to cut downward along the mating surface of mounting plate 2, accurately cutting off the connecting filaments between the pulp outlet 3 and the molded product in the falling trajectory. Afterward, gate 9 always maintains a physical barrier in front of the pulp outlet 3, effectively preventing pulp from overflowing from the pulp outlet 3 before the subsequent injection process begins, thereby achieving the purpose of preventing filament hanging and pulp overflow. This solves the problem that the existing pulp molding packaging online forming device lacks the function of scraper sealing. Without the scraper sealing function, there may be a need to stop the machine frequently for cleaning and pulp may overflow continuously, resulting in reduced production efficiency and material waste.
