Description

Technical Field

[0001] This utility model belongs to the field of pulp molding product manufacturing technology, and specifically relates to a multi-station rotary table blank taking machine for pulp molding products. Background Technology

[0002] Pulp molding products are environmentally friendly packaging products made from renewable plant fibers such as waste paper and bagasse through processes such as pulping, pulping, molding, and drying. These products are widely used in food packaging, electronic device protection, and agricultural product transportation due to their renewable raw materials, low pollution during production, and biodegradable and recyclable properties, which aligns with the global trend of green packaging industry development.

[0003] In the production of pulp molded products, in order to avoid the wet blank from sticking to the mold, a release agent must be applied to the inner wall in advance, and then the pulp is injected and shaped by the pressure forming mechanism. In the current process, the release agent spraying, pulp injection, compaction and molding and blank removal are all concentrated in the same station, which means that only one pulp molded product can be produced in a single operation. Due to the superposition of station functions, there is redundant waiting time between processes, which makes it impossible to achieve continuous operation and seriously restricts the production line cycle time and overall efficiency. Utility Model Content

[0004] In view of the problem that multiple processes are concentrated in one station when producing pulp molded products, this utility model proposes a multi-station rotary blank taking machine for pulp molded products to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a multi-station rotary blank taking machine for pulp molding products, including a support frame. A rotating component is provided on the top of the support frame. A plurality of mold components are provided on the top of the rotating component. An extrusion injection component, a material taking component, and a brushing component are arranged sequentially on the outside of the rotating component. An elastic connecting component is provided at the bottom of the mold component. A guide component is provided on the top of the support frame corresponding to the elastic connecting component.

[0007] The rotating assembly is used to drive several mold assemblies to rotate intermittently, so that the mold assemblies pass through the extrusion injection assembly, the material taking assembly and the painting assembly in sequence. At the same time, the guide assembly can lift the mold assembly through the elastic connection assembly so that the pulp molded product moves to the upper side of the rotating assembly.

[0008] Furthermore, the rotating assembly includes a mounting cylinder, which is fixedly connected to the top of the support frame. A rotating ring is rotatably connected to the outer side of the mounting cylinder, and a rotating disk is fixedly connected to the top of the rotating ring. A drive motor is fixedly installed on the top of the inner wall of the mounting cylinder, and the output end of the drive motor passes through the mounting cylinder and is fixedly connected to the rotating disk.

[0009] Furthermore, the mold assembly includes a through groove, and multiple through grooves are arranged in a circumferential array on the top of the rotating disk. A box edge groove is formed on the top of the rotating disk corresponding to the through groove, and a mold box is movably connected inside the through groove.

[0010] Furthermore, the extrusion injection molding assembly includes a mounting frame, which is fixedly connected to a support frame. A hydraulic cylinder is fixedly mounted on the top of the mounting frame, and the output end of the hydraulic cylinder passes through the mounting frame and is fixedly connected to an extrusion box. An injection tube is fixedly connected to the top of the extrusion box.

[0011] Furthermore, the material handling assembly includes a first robotic arm, which is disposed on the outside of the support frame, and a vacuum suction cup is provided at the moving end of the first robotic arm.

[0012] Furthermore, the painting assembly includes a second robotic arm, which is disposed on the outside of the support frame. The moving end of the second robotic arm is provided with a conductive slide rail, and a conductive slider is movably connected to the outside of the conductive slide rail. A brush frame is fixedly connected to the bottom of the conductive slider. A connecting frame is fixedly connected to the outside of the support frame, and a material box is fixedly connected to one side of the connecting frame.

[0013] Furthermore, the elastic connection assembly includes a fixing frame, which is fixedly installed on the outside of the rotating disk. Multiple fixing frames are provided corresponding to the through slots. A T-shaped block is movably connected inside the fixing frame. The T-shaped block is fixedly installed at the bottom of the mold box. A T-shaped rod is fixedly connected to the bottom of the T-shaped block. The T-shaped rod passes through the fixing frame. A spring is fixedly connected between the bottom of the fixing frame and the bottom end of the T-shaped rod.

[0014] Furthermore, the guide assembly includes an arc-shaped guide plate, which is fixedly connected to the top of the support frame. The inner wall of the arc-shaped guide plate is provided with a spiral groove, and a guide rod is fixedly connected to the outer side of the T-shaped block.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model allows several mold components to rotate at a certain angle via a rotating component. The extrusion injection component, material handling component, and powder brushing component can correspond to one of the mold components. This arrangement enables the release agent spraying, product injection molding, and blank handling to be performed simultaneously at different positions, significantly shortening the equipment downtime in the pulp molding product production process, effectively improving the continuity of the production process, and thus greatly improving the overall production efficiency.

[0017] 2. This utility model uses a drive motor to rotate a rotating disk. The rotating disk can drive the mold box containing the molded pulp product to rotate towards the first robotic arm. During this process, the guide rod can move into the interior of the spiral groove, so that the spiral groove continuously pushes the mold box upward through the guide rod and the T-block. When the mold box rotates to the vacuum suction cup, the edge of the molded pulp product also completely moves out of the interior of the groove, so that the vacuum suction cup can complete the adsorption and demolding of the product through the edge of the box. The above setting realizes continuous operation of multiple stations through the linkage of rotation indexing and lifting, significantly reducing idle waiting between processes, while avoiding product deformation caused by manual intervention, and improving the automation level of the production line and product consistency.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figure 1 - Figure 7 As shown, this utility model is a multi-station rotary blank taking machine for pulp molding products, including a support frame 1. A rotating component 2 is provided on the top of the support frame 1. A plurality of mold components 3 are provided on the top of the rotating component 2. An extrusion injection component 4, a material taking component 5 and a powder brushing component 6 are arranged sequentially on the outside of the rotating component 2. An elastic connecting component 7 is provided at the bottom of the mold component 3. A guide component 8 is provided on the top of the support frame 1 corresponding to the elastic connecting component 7.

[0032] The rotating component 2 is used to drive several mold components 3 to rotate intermittently, so that the mold components 3 pass through the extrusion injection component 4, the material taking component 5 and the painting component 6 in sequence. At the same time, the guide component 8 can lift the mold components 3 through the elastic connecting component 7, so that the pulp molded product moves to the upper side of the rotating component 2.

[0033] The rotating component 2 drives several mold components 3 to rotate intermittently. When the mold component 3 rotates to a predetermined angle, the extrusion injection component 4 injects the slurry into the interior of the corresponding mold component 3 and extrudes the mold component 3. Meanwhile, the material grabbing component 5 grabs the pulp molded product formed inside the corresponding mold component 3 and transfers it. The powdering component 6 applies the release agent to the interior of the corresponding mold component 3. After all the above operations are completed, the rotating component 2 drives several mold components 3 to rotate again at a certain angle, and the above operations are repeated.

[0034] After the rotating component 2 drives several mold components 3 to rotate at a certain angle, the extrusion injection component 4, the material taking component 5, and the brushing component 6 can correspond to one of the mold components 3. This setting allows the release agent spraying, product injection molding, and blank taking actions to be carried out simultaneously at different positions, which significantly shortens the equipment downtime in the pulp molding product production process, effectively improves the continuity of the production process, and thus greatly improves the overall production efficiency.

[0035] In one embodiment, the rotating assembly 2 includes a mounting cylinder 201, which is fixedly connected to the top of the support frame 1. A rotating ring 202 is rotatably connected to the outer side of the mounting cylinder 201, and a rotating disk 203 is fixedly connected to the top of the rotating ring 202. A drive motor 204 is fixedly installed on the top of the inner wall of the mounting cylinder 201, and the output end of the drive motor 204 passes through the mounting cylinder 201 and is fixedly connected to the rotating disk 203.

[0036] The rotating disk 203 is driven by the drive motor 204, allowing it to rotate at the top of the mounting cylinder 201. When the rotating disk 203 rotates, the rotating ring 202 can rotate on the outside of the mounting cylinder 201. This arrangement ensures the stability of the rotating disk 203 during rotation. At the same time, the drive motor 204 drives the rotating disk 203 intermittently, allowing it to stop after rotating a certain angle. This enables the subsequent extrusion injection assembly 4, material handling assembly 5, and powder coating assembly 6 to simultaneously perform corresponding operations on the mold assembly 3.

[0037] In one embodiment, the mold assembly 3 includes a through groove 301, a plurality of through grooves 301 are arranged in a circular array on the top circumference of the rotating disk 203, and a box edge groove 302 is provided on the top of the rotating disk 203 corresponding to the through groove 301. A mold box 303 is movably connected inside the through groove 301.

[0038] The extrusion injection molding component 4 can inject slurry into the mold box 303 and the box edge groove 302. After the pulp molded product is formed inside the mold box 303 and the box edge groove 302, the mold box 303 can be pushed upward, so that the mold box 303 can move upward along the through groove 301. At the same time, the box edge part of the formed product can be moved out from inside the box edge groove 302. This setting makes it more convenient for the subsequent material handling component 5 to transfer the formed product.

[0039] In one embodiment, the extrusion injection molding assembly 4 includes a mounting frame 401, which is fixedly connected to a support frame 1. A hydraulic cylinder 402 is fixedly mounted on the top of the mounting frame 401. The output end of the hydraulic cylinder 402 passes through the mounting frame 401 and is fixedly connected to an extrusion box 403. An injection tube 404 is fixedly connected to the top of the extrusion box 403.

[0040] The injection tube 404 is connected to an external device for collecting the slurry. When one of the mold boxes 303 rotates to the bottom of the extrusion box 403 under the drive of the rotating disk 203, the hydraulic cylinder 402 drives the extrusion box 403 to move downward and cover the box edge groove 302 and the mold box 303. At this time, the slurry can be directly moved into the box edge groove 302 and the mold box 303 through the injection tube 404, so that the slurry is formed under the cooperation of the extrusion box 403, the box edge groove 302 and the mold box 303.

[0041] In one embodiment, the material handling component 5 includes a first robotic arm 501, which is disposed on the outside of the support frame 1, and a vacuum suction cup 502 is provided at the moving end of the first robotic arm 501.

[0042] As the rotating disk 203 drives the mold box 303 to rotate intermittently, when the mold box 303, which contains the molded pulp product, rotates to the vacuum suction cup 502, the vacuum suction cup 502 is moved to the top of the mold box 303 by the first robotic arm 501, so that the vacuum suction cup 502 can adsorb the molded pulp product, and at the same time, the molded pulp product moves out of the mold box 303 under the adsorption of the vacuum suction cup 502.

[0043] In one embodiment, the painting assembly 6 includes a second robotic arm 601, which is disposed on the outside of the support frame 1. The moving end of the second robotic arm 601 is provided with a conductive slide rail 602. A conductive slider 603 is movably connected to the outside of the conductive slide rail 602. A brush frame 604 is fixedly connected to the bottom of the conductive slider 603. A connecting frame 605 is fixedly connected to the outside of the support frame 1. A material box 606 is fixedly connected to one side of the connecting frame 605.

[0044] The material box 606 contains a release agent. When the mold box 303, which has finished picking up the material, rotates to the second robotic arm 601, the second robotic arm 601 moves the brush frame 604 from the inside of the material box 606 to the inside of the mold box 303. At this time, the brush tip of the brush frame 604 contacts the inner wall of the mold box 303. Then, the conductive slide rail 602 moves the brush frame 604 inside the mold box 303 through the conductive slider 603, so that the release agent on the brush frame 604 can be directly applied to the inside of the mold box 303.

[0045] In one embodiment, the elastic connection component 7 includes a fixing frame 701, which is fixedly installed on the outside of the rotating disk 203. Multiple fixing frames 701 are provided corresponding to the through slots 301. A T-shaped block 702 is movably connected inside the fixing frame 701. The T-shaped block 702 is fixedly installed on the bottom of the mold box 303. A T-shaped rod 703 is fixedly connected to the bottom of the T-shaped block 702. The T-shaped rod 703 passes through the fixing frame 701. A spring 704 is fixedly connected between the bottom of the fixing frame 701 and the bottom end of the T-shaped rod 703.

[0046] When the molded pulp product inside the mold box 303 is formed and rotated to the vacuum suction cup 502, it pushes the T-block 702 upward, causing the T-block 702 to press the spring 704 upward through the T-rod 703. At the same time, the mold box 303 can drive the molded pulp product to move upward, so that the edge of the molded pulp product moves out of the inside of the edge groove 302. The spring 704 can push the T-block 702 downward through the T-rod 703, so that the T-block 702 contacts the inner wall of the fixing frame 701. This arrangement prevents the mold box 303 from shaking randomly inside the groove 301 when performing other operations.

[0047] In one embodiment, the guide component 8 includes an arc-shaped guide plate 801, which is fixedly connected to the top of the support frame 1. The inner wall of the arc-shaped guide plate 801 is provided with a spiral groove 802, and a guide rod 803 is fixedly connected to the outer side of the T-shaped block 702.

[0048] After the mold box 303 containing the molded pulp product rotates to the predetermined position, the guide rod 803 can move into the spiral groove 802. At this time, as the mold box 303 continues to rotate, the spiral groove 802 squeezes the T-block 702 upward through the guide rod 803, so that the mold box 303 moves upward while rotating. When the mold box 303 rotates to the vacuum suction cup 502, the edge of the molded pulp product also moves completely out of the inside of the edge groove 302. After the molded pulp product is transferred out of the mold box 303, as the mold box 303 moves, the guide rod 803 can move out from the inside of the spiral groove 802. At this time, the spring 704 pulls the T-block 702 downward through the T-rod 703, so that the mold box 303 is reset under the action of the T-block 702.

[0049] Through the above technical solution, 1. After the rotating component 2 drives several mold components 3 to rotate at a certain angle, the extrusion injection component 4, the material handling component 5, and the brushing component 6 can correspond to one of the mold components 3. This setting allows the release agent spraying, product injection molding, and blank handling actions to be performed simultaneously at different positions, significantly shortening the equipment downtime in the pulp molded product production process, effectively improving the continuity of the production process, and thus greatly improving the overall production efficiency; 2. The drive motor 204 rotates the rotating disk 203, and the rotating disk 203 can drive the mold box 303 containing the molded pulp molded product to the first mechanical... The arm 501 rotates, during which the guide rod 803 can move into the interior of the spiral groove 802, thereby causing the spiral groove 802 to continuously push the mold box 303 upward through the guide rod 803 and the T-block 702. When the mold box 303 rotates to the vacuum suction cup 502, the edge of the pulp molded product also completely moves out of the interior of the edge groove 302, thereby allowing the vacuum suction cup 502 to complete the adsorption and demolding of the product through the edge of the box. The above settings, through the linkage of rotation indexing and lifting, realize multi-station continuous operation, significantly reduce idle waiting between processes, and avoid product deformation caused by manual intervention, thereby improving the automation level of the production line and product consistency.
