Description

Technical Field

[0001] This utility model relates to the field of mold support frame technology, and in particular to an adjustable pulp molding mold support frame. Background Technology

[0002] Pulp molding die support frames are key devices used to fix and support the molds in the pulp molding production process. Their main function is to ensure that the molds maintain a stable position and posture during molding, drying, and other processes, thereby guaranteeing the dimensional accuracy and molding quality of the pulp molded products. This device is usually installed at the corresponding station of the pulp molding production equipment, working in conjunction with the mold to complete the entire production process. It is an important intermediate component connecting the production equipment and the mold.

[0003] The equipment related to pulp molding die support frames mainly includes pulp molding machines and molds. A pulp molding machine generally consists of a pulping structure, a molding structure, and a drying structure. The pulping structure processes waste paper and other raw materials into pulp, which is then transported to the molding structure via pipelines. Within the molding structure, the mold, fixed by the support frame, is immersed in the pulp or receives sprayed pulp, allowing the pulp to evenly adhere to the mold surface to form a wet preform. Subsequently, the mold with the wet preform is transported to the drying structure, where moisture is removed through heating or other methods, ultimately forming the pulp molded product. The mold is designed according to the shape and size of the product and typically consists of a molding mesh, a mold frame, and other structures. The precision of its fit with the support frame directly affects the production efficiency and quality of the product.

[0004] In existing technologies, the dimensions of pulp molding die support frames are mostly fixed. When it is necessary to change to different specifications of die, due to differences in die size, mounting hole positions, and other parameters, the fixed-size support frame cannot effectively match the new die. Operators need to replace the entire support frame or make complex modifications to continue production. This not only increases equipment replacement and time costs but also reduces production flexibility and continuity, adversely affecting the efficiency of pulp molding production. Therefore, an adjustable pulp molding die support frame is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable pulp molding die support frame, which aims to improve the problem of fixed support frame size and low adaptability to different molds in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable pulp molding die support frame includes a pulp tank and a support frame. The support frame is located inside the pulp tank. A running component is provided on the top of the pulp tank. A quick-release component is provided on the top of the support frame. Multiple fixing nuts are provided on the top of the support frame. A hydraulic rod is threaded to the bottom of each fixing nut. The bottoms of the multiple hydraulic rods are fixedly connected to the top of the inner wall of the pulp tank. An adjustable component is provided at the bottom of the support frame.

[0011] As a further description of the above technical solution:

[0012] The operating components include a frame and multiple hydraulic rods. The outer wall of the frame is fixedly connected to the top of the pulp tank, and the multiple hydraulic rods are slidably connected inside the frame. An upper mold is fixedly connected to the bottom of the multiple hydraulic rods.

[0013] As a further description of the above technical solution:

[0014] The quick-release assembly includes a locking block located at the top of the support frame. A lower mold is fixedly connected to the top of the locking block, and the locking block is slidably connected inside the sliding support plate.

[0015] As a further description of the above technical solution:

[0016] The card block is slidably connected to a card post inside, and the card post is slidably connected inside the sliding support plate. A limit plate is provided on one side of the card post.

[0017] As a further description of the above technical solution:

[0022] A spring is provided on one side of the button plate. One end of the spring is fixedly connected to the bottom of the button plate, and the other end of the spring is fixedly connected to a fixing plate.

[0023] This utility model has the following beneficial effects:

[0024] In this invention, the rotating rod drives the threaded rod to rotate, which can adjust the sliding support plate to a suitable position to adapt to molds of different sizes. When the mold size changes, there is no need to replace the support frame. Only the spacing needs to be adjusted to quickly switch the production state, which solves the problem of frequent support frame replacement that greatly reduces production efficiency in small-batch, multi-variety production scenarios.

[0025] In this invention, by controlling the engagement of the locking post and the locking block groove by pressing the plate, the mold can be disassembled and installed in a short time, which greatly shortens the mold change time and solves the problem that traditional molds are mostly fixed by fasteners such as bolts and nuts, and disassembly and installation require tightening them one by one, which is time-consuming and laborious.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-5 The present invention provides an embodiment of an adjustable pulp molding die support frame, comprising a pulp tank 1 and a support frame 6. The pulp tank 1 is used to contain pulp raw materials and provide molding space. The support frame 6 is used to support the die and provide support for the adjustable components. The support frame 6 is located inside the pulp tank 1. A running component is provided on the top of the pulp tank 1. A quick-release component is provided on the top of the support frame 6. Multiple fixing nuts 7 are provided on the top of the support frame 6. The fixing nuts 7 are used to connect hydraulic rods 9 and fix the support frame 6. Each fixing nut 7 is threaded to the bottom of a hydraulic rod 9. The hydraulic rods 9 are used to precisely control the lifting and lowering movement of the support frame 6. The bottoms of the multiple hydraulic rods 9 are fixedly connected to the top of the inner wall of the pulp tank 1. An adjustable component is provided at the bottom of the support frame 6.

[0037] The adjustable assembly includes multiple sliding support plates 8, which support the mold and allow for horizontal position adjustment. These plates are slidably connected to the outer wall of the support frame 6. Each sliding support plate 8 has a slider 13 fixedly connected to its bottom. The slider 13 connects the threaded rod 11 to the sliding support plate 8, serving a transmission function. The slider 13 has a threaded connection to the threaded rod 11, which converts rotational motion into linear motion. Fixed blocks 10 are rotatably connected to both ends of the threaded rod 11, fixing its position and maintaining it in a set position. The top of the fixed blocks 10 is fixedly connected to the bottom of the support frame 6. A rotating assembly, including a rotating rod, is located on one side of the threaded rod 11. 14. The rotating rod 14 is located on one side of the threaded rod 11. One end of the rotating rod 14 has an interface 16. One end of the threaded rod 11 is fixedly connected to a connector 12. The connector 12 fits inside the interface 16. The interface 16 is used to cooperate with the connector 12 to realize power transmission, while ensuring that the rotating rod 14 is detachable to avoid collision with the pulp tank 1 during the lifting and lowering of the support frame 6. One end of the rotating rod 14 is rotatably connected to a handle 15. The handle 15 is used to manually adjust the position of the sliding support plate 8. The running components include the frame 2 and multiple hydraulic rods 5. The outer wall of the frame 2 is fixedly connected to the top of the pulp tank 1. The multiple hydraulic rods 5 are slidably connected inside the frame 2. The bottom of the multiple hydraulic rods 5 is fixedly connected to the upper mold 3. The running components here are existing technologies and will not be described in detail.

[0038] Reference Figure 1 , Figure 6 and Figure 7The quick-release assembly includes a locking block 21, which connects the lower mold 4 and the sliding support plate 8. The block 21 has grooves on its surface for the locking post 20 to engage. The locking block 21 is located at the top of the support frame 6, and the lower mold 4 is fixedly connected to the top of the locking block 21. The lower mold 4 is used for pulp forming and cooperates with the upper mold 3 to form a wet mold. This is prior art. The locking block 21 is slidably connected inside the sliding support plate 8, and the locking post 20 is slidably connected inside the locking block 21. The locking post 20 is used to lock the position of the locking block 21. The locking post 20 is slidably connected inside the sliding support plate 8, and a limit plate 22 is provided on one side of the locking post 20. The limit plate 22 limits the range of movement of the locking post 20 and also limits the sliding direction of the pressing plate 19, so that the pressing plate 19 only... The sliding support plate 8 has a sliding groove 23 on its inner wall, which guides the movement trajectory of the limiting plate 22. The limiting plate 22 is slidably connected inside the sliding groove 23. A button plate 19 is fixedly connected to one side of the limiting plate 22. The button plate 19 is used to manually control the movement space of the locking post 20. A fixing plate 18 is fixedly connected to one side of the sliding support plate 8. The fixing plate 18 is used to fix the installation position of the spring 17. A spring 17 is provided on one side of the button plate 19. The spring 17 is used to provide the reset elastic force of the button plate 19, so that the button plate 19 and the limiting plate 22 fix the locking post 20 in the groove to play a locking role. One end of the spring 17 is fixedly connected to the bottom of the button plate 19, and the other end of the spring 17 is fixedly connected to the fixing plate 18.

[0039] Working principle: When supporting molds of different sizes, first activate hydraulic rod 29 to raise support frame 6 from inside pulp tank 1 for easy operation. Then align the interface 16 at the top of rotating rod 14 with connector 12 for installation. Next, hold handle 15 and rotate rotating rod 14, causing threaded rod 11 to rotate under the fixation of fixing blocks 10 at both ends. At this time, sliders 13 at both ends slide inward and outward, moving sliding support plate 8 to a suitable position to adapt to molds of different sizes. When the mold size changes, there is no need to replace the support frame. Only the spacing needs to be adjusted to quickly switch production status, solving the problem of frequent support frame replacement that greatly reduces production efficiency in small-batch, multi-variety production scenarios.

[0040] After the support frame is adjusted and the lower mold 4 is installed, first press down the press plate 19. Since the limiting plate 22 fixed to the press plate 19 is engaged in the slide groove 23, the press plate 19 can only move down in the vertical direction and compress the spring 17. At this time, the locking post 20 can leave the groove of the locking block 21, releasing the lock between the lower mold 4 and the sliding support plate 8, and the installation and disassembly of the lower mold 4 can be carried out. Then release the press plate 19. Under the reaction force of the spring 17, the press plate 19 will re-engage the locking post 20 in the locking block 21 and the sliding support plate 8. The mold disassembly and installation can be completed in a short time, greatly shortening the mold change time. This solves the problem that traditional molds are mostly fixed by bolts, nuts and other fasteners, and disassembly and installation require tightening one by one, which is time-consuming and laborious.
