Description

Technical Field

[0001] This utility model relates to the field of pulp molded products, specifically an environmentally friendly pulp molded product trimming device. Background Technology

[0002] Pulp molding is a papermaking technology that uses waste paper as raw material. It involves pulp preparation, adsorption molding, drying, and shaping processes, and has four major advantages: the raw material is waste paper, making it widely available; the production process is environmentally friendly and harmless; it is recyclable; and it is smaller in volume than foamed plastics, allowing for stacking and convenient transportation. Under the backdrop of plastic bans and dual-carbon policies, the pulp molding industry has experienced rapid development. Many countries have successively introduced regulations restricting single-use plastic products, driving demand for pulp molding as an alternative. At the same time, the utilization of agricultural waste such as crop straw has received significant attention, aligning with the development direction of the circular economy. In terms of technological innovation, the industry is moving towards raw material diversification, formula upgrades, and intelligent manufacturing processes.

[0003] Environmentally friendly pulp molding is affected by factors such as raw material sources and process characteristics. For example, when using vacuum adsorption molding, the fibers in the edge area tend to aggregate in a flocculent manner when the liquid pulp is deposited on the mold surface, forming irregular burrs. This is because the filter screen at the edge of the mold cannot completely control the orientation of the fibers, resulting in uneven edges after the product is demolded. Edge defects are unavoidable and need to be eliminated by trimming the edges to remove weak points in the fibers, improve the compressive strength of the product edges, and avoid overall structural failure due to edge tearing.

[0004] In the current process of trimming pulp molded products, the cut-off scraps often simply fall into the collection mechanism. Over a long period of trimming, the scraps accumulate and eventually block the scrap drop-off point, affecting the trimming effect. To address this, we propose an environmentally friendly trimming device for pulp molded products. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly pulp molding product trimming device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, an environmentally friendly pulp molding product trimming device includes a trimming table. A cylinder is fixedly installed at the upper end of the trimming table, and the movable end of the cylinder is fixedly installed on the top of the movable table. A cutting mechanism is fixedly installed on the lower side of the movable table. A slicing groove is formed on the surface of the trimming table below the cutting mechanism. A sorting mechanism is provided at one end of the trimming table. The sorting mechanism includes a collection unit and a driving unit. The collection unit is used to receive the trimmed scraps falling from the slicing groove, and the driving unit is used to push the collection unit to move laterally back and forth.

[0007] Furthermore: the collecting unit includes a collecting cavity, which is opened on the outer wall of the cutting table. A collecting box is provided inside the collecting cavity. A handle is fixedly connected to one end of the collecting box facing the outside of the collecting cavity. A ball bearing is provided at the bottom of the inner wall of the collecting cavity.

[0008] Furthermore: the drive unit includes a toothed plate, which is fixedly connected to the back of the movable table, and a toothed shaft is rotatably connected to the outer wall of the cutting table. The lower end of the toothed plate extends vertically downward and meshes with one end of the toothed shaft.

[0009] Furthermore: one end of the gear shaft extends laterally and a transmission belt is provided on its surface; the other end of the transmission belt is sleeved on the outside of the follower shaft; the follower shaft is rotatably connected to the outside of the cutting table via the transmission belt.

[0010] Furthermore: a rotating plate is fixedly connected to the outer end of the follower shaft, a crossbar is fixedly connected to the outer wall of the rotating plate, one end of the crossbar is movably connected to the inner side of the vertical frame, and the surface of the crossbar is a smooth surface.

[0011] Furthermore, the top of the handle is provided with a groove that matches the size of the vertical frame.

[0012] Furthermore: the cutting mechanism includes spring cylinders, a plurality of spring cylinders are fixedly installed on the lower surface of the movable table, the movable ends of the spring cylinders are all fixedly installed on the top of the pressure plate, and slices are fixedly installed on the upper side of the slicing groove on the lower surface of the movable table.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, when the movable platform descends, the toothed plate can move with the vertical movement of the movable platform. During the movement, the toothed plate meshes with the toothed shaft, driving the toothed shaft to rotate. The toothed shaft, through the transmission belt, also drives the follower shaft to rotate together. The follower shaft, through the rotating plate and the crossbar, controls the vertical frame to continuously drive the handle to move horizontally back and forth, so that the cut edges and scraps falling into the collection box are continuously vibrated and shaken evenly, and will not pile up too high under the slicing groove. The collection box can also be easily taken out from the collection cavity. 2. The toothed plate can move with the vertical movement of the moving table and only needs to be activated when performing edge cutting operations. No additional motor drive is required, making it more efficient and environmentally friendly than the usual sorting method. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Please see Figure 1-4 The figure shows a preferred embodiment of the present invention, an environmentally friendly pulp molding product trimming device, including a trimming table 1, a cylinder 2 fixedly installed at the upper end of the trimming table 1, the movable end of the cylinder 2 fixedly installed at the top of the movable table 3, a cutting mechanism 4 fixedly installed at the lower side of the movable table 3, a slicing groove 5 opened on the surface of the trimming table 1 at the lower side of the cutting mechanism 4, and a sorting mechanism 6 provided at one end of the trimming table 1, the sorting mechanism 6 including a collecting unit 7 and a driving unit 8, the collecting unit 7 is used to receive the trimmed scraps falling from the slicing groove 5, and the driving unit 8 is used to push the collecting unit 7 to move laterally back and forth.

[0018] Specifically, the collection unit 7 includes a collection cavity 9, which is located on the outer wall of the cutting table 1. A collection box 10 is installed inside the collection cavity 9. A handle 11 is fixedly connected to one end of the collection box 10 facing the outside of the collection cavity 9. A ball bearing is installed at the bottom of the inner wall of the collection cavity 9. The collection box 10 is used to collect the cut scraps. The ball bearing installed on the bottom surface of the collection cavity 9 allows the collection box 10 to move easily inside the collection cavity 9. The collection box 10 is equipped with casters, and the height of the casters does not affect the contact between the ball bearing and the bottom of the collection box 10.

[0019] It is understood that the drive unit 8 includes a toothed plate 12, which is fixedly connected to the back of the movable table 3. The outer wall of the cutting table 1 is rotatably connected to a toothed shaft 13. The lower end of the toothed plate 12 extends vertically downward and meshes with one end of the toothed shaft 13. The toothed plate 12 can move with the vertical movement of the movable table 3. During the movement, the toothed plate 12 meshes with the toothed shaft 13, driving the toothed shaft 13 to rotate. It should be noted that the teeth and gear teeth on the toothed plate 12 and the toothed shaft 13 are not shown in the figure.

[0020] One end of the gear shaft 13 extends laterally and is provided with a transmission belt 14 on its surface. The other end of the transmission belt 14 is sleeved on the outside of the follower shaft 15. The follower shaft 15 is rotatably connected to the outside of the cutting table 1 through the transmission belt 14. When the gear shaft 13 rotates through the transmission belt 14, it also drives the follower shaft 15 to rotate together.

[0021] To extend the moving distance of the collection box 10, a rotating plate 16 is fixedly connected to the outer end of the follower shaft 15. A crossbar 17 is fixedly connected to the outer wall of the rotating plate 16. One end of the crossbar 17 is movably connected to the inner side of the vertical frame 18. The surface of the crossbar 17 is a smooth surface to prevent the vertical frame 18 from being pushed upward when it contacts the vertical frame 18.

[0022] To ensure that the vertical frame 18 is stably positioned on the upper side of the handle 11, the top of the handle 11 is provided with a groove 19 that matches the size of the vertical frame 18.

[0023] The cutting mechanism 4 includes spring cylinders 20. Several spring cylinders 20 are fixedly installed on the lower surface of the movable table 3. The movable ends of the spring cylinders 20 are all fixedly installed on the top of the pressure plate 21. A slice 22 is fixedly installed on the upper side of the slicing groove 5 on the lower surface of the movable table 3. The lowest point of the pressure plate 21 is lower than the lowest point of the slice 22, so that the pulp molded product is lifted and pressed before the edge is cut, and finally the cutting is completed by the slice 22.

[0024] In this embodiment, the environmentally friendly pulp molded product to be trimmed is placed on the surface of the trimming table 1. After alignment, the cylinder 2 starts to drive the lower side of the movable table 3. Since the lowest point of the pressure plate 21 is lower than the lowest point of the slice 22, before trimming, the slice 22 is lifted to press down on the pulp molded product. After pressing down on the pulp molded product, the slice 22 can continue to move downward through the spring cylinder 20. Finally, the cutting is completed by the slice 22, and the trimmed scraps fall into the collection chamber 9 through the slice groove 5. When the movable platform 3 descends, the toothed plate 12 can move with the vertical movement of the movable platform 3. During the movement, the toothed plate 12 meshes with the toothed shaft 13, driving the toothed shaft 13 to rotate. The toothed shaft 13, through the transmission belt 14, also drives the follower shaft 15 to rotate together. The follower shaft 15, through the rotating plate 16 and the crossbar 17, controls the vertical frame 18 to continuously drive the handle 11 to move horizontally back and forth, so that the cut edges and scraps falling into the collection box 10 are continuously vibrated and shaken evenly, and will not pile up too high under the slicing trough 5.
