Description

Technical Field

[0001] This utility model relates to the field of tableware production technology, and more specifically to a biodegradable tableware pressing device. Background Technology

[0002] As an important alternative to traditional disposable plastic tableware, biodegradable tableware has seen explosive growth in market demand. Plant fibers such as sugarcane pulp and bamboo pulp are ideal raw materials for producing environmentally friendly tableware due to their wide availability, renewability, complete biodegradability, and harmless degradation products. They are especially suitable for making products such as lunch boxes, plates, knives, forks, and spoons.

[0003] Currently, the mainstream molding process for plant fiber tableware is wet molding. The general process is as follows: plant fiber raw materials are mixed with water and additives to make pulp, wet blanks are formed by the suction action of molding molds, and then the finished products are obtained by high temperature and high pressure hot pressing and subsequent drying. The core molding and shaping steps rely on specialized wet molding equipment.

[0004] Nowadays, when tableware is pressed and formed using molds, the temperature of the pressed tableware is relatively high, and the tableware is prone to sticking to the bottom of the upper mold. Removing it wastes processing time. Furthermore, it is impossible to fully observe the mold during the pressing and forming process, which is not conducive to adjusting the forming process. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a biodegradable tableware pressing device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a biodegradable tableware pressing device, including a lower mold, a pressing die fixedly connected to the top of the lower mold, an upper mold above the pressing die, a pressing punch fixedly connected to the bottom of the upper mold, a material discharge and cooling mechanism connected to both sides inside the upper and lower molds, and a detection mechanism fixedly connected to the bottom of the upper mold; the material discharge and cooling mechanism includes a rack fixedly connected to the lower mold, a connecting gear meshing on the side of the rack, a connecting shaft fixedly connected inside the connecting gear, a synchronizing gear fixedly connected to the side of the connecting shaft away from the connecting gear, an output gear meshing at the bottom of the synchronizing gear, an output shaft fixedly connected inside the output gear, a blade assembly fixedly connected to the side of the output shaft, a conical cylinder provided on the side of the blade assembly, a connecting pipe fixedly connected to the side of the conical cylinder away from the blade assembly, and an exhaust pipe fixedly connected to the side of the connecting pipe near the pressing die.

[0007] Furthermore, the outlet of the material feeding and cooling mechanism is located above the pressing die, the position of the pressing punch corresponds to the position of the pressing die, and guide sleeve assemblies are fixedly connected to both sides of the top of the lower die, with the top of the guide sleeve assembly fixedly connected to the bottom of the upper die.

[0008] Furthermore, the exhaust pipe is inclined downwards at ten degrees from the connecting pipe side to the pressing die side, and there are four exhaust pipes, which are evenly distributed above the pressing die.

[0009] Furthermore, a fixing plate is fixedly connected to the top of the conical cylinder, and the top of the fixing plate is fixedly connected to the bottom of the upper mold. Support plates are movably connected to the sides of the connecting shaft and the output shaft away from the conical cylinder, and the top of the support plates is fixedly connected to the bottom of the upper mold.

[0010] Furthermore, the detection mechanism includes a supportable limiting box, a movable plate is movably connected inside the limiting box, a detection head is fixedly connected to the bottom end of the movable plate, and a threaded rod is threadedly connected inside the movable plate.

[0011] Furthermore, a rotating wheel is fixedly connected to the top of the threaded rod, a slider is fixedly connected to the top of the side of the movable plate, and a groove is provided on the side of the limiting box for the slider to move.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model is equipped with a connecting gear, a rack, an output gear, and a blade assembly. During the pressing and molding process, the mold is formed. When the mold is opened after molding, the upper mold moves upward, which drives the connecting gear to move upward. When the connecting gear moves upward, it meshes with the rack, so the connecting gear will rotate. When the connecting gear rotates, it drives the output gear to rotate faster through the synchronous gear. When the output gear rotates, it drives the blade assembly to rotate. When the blade assembly rotates, it blows gas into the mold and then sprays it downward. The gas blows to the bottom of the pressing punch, blows off the tableware stuck to the pressing punch, and cools it down.

[0014] 2. This utility model is equipped with a rotating wheel, a threaded rod, a detection head, and a moving plate. When the rotating wheel is rotated, it drives the threaded rod to rotate. When the threaded rod rotates, it causes the moving plate to move up and down. When the moving plate moves up and down, it drives the detection head to move up and down. Therefore, the detection head can monitor different positions, thereby understanding the state of the pressing punch and pressing die when they are pressed together, and thus can be adjusted in time.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 and Figure 2 This utility model provides a biodegradable tableware pressing device, including a lower mold 1, a pressing die 2 fixedly connected to the top of the lower mold 1, an upper mold 3 above the pressing die 2, a pressing punch 4 fixedly connected to the bottom of the upper mold 3, a material discharge and cooling mechanism 6 connected to both sides inside the upper mold 3 and the lower mold 1, a detection mechanism 7 fixedly connected to the bottom of the upper mold 3, the outlet of the material discharge and cooling mechanism 6 being located above the pressing die 2, the position of the pressing punch 4 corresponding to the position of the pressing die 2, and guide sleeve assemblies 5 fixedly connected to both sides of the top of the lower mold 1, the top of the guide sleeve assembly 5 being fixedly connected to the bottom of the upper mold 3.

[0023] In this embodiment, the outlet of the material cooling mechanism 6 is located above the pressing die 2. Therefore, when the material cooling mechanism 6 is running instead of blowing out gas, the blown gas will blow to the top of the pressing die 2, which facilitates the demolding of the pressing punch 4 from the tableware and can cool the pressing punch 4 to avoid damage.

[0024] Reference Figure 3 and Figure 4 The material unloading and cooling mechanism 6 includes a rack 601 fixedly connected to the lower mold 1. A connecting gear 602 meshes with the side of the rack 601. A connecting shaft 603 is fixedly connected inside the connecting gear 602. A synchronizing gear 604 is fixedly connected to the side of the connecting shaft 603 away from the connecting gear 602. An output gear 605 meshes with the bottom end of the synchronizing gear 604. An output shaft 606 is fixedly connected inside the output gear 605. A blade assembly 607 is fixedly connected to the side of the output shaft 606. A conical cylinder 609 is provided on the side of the blade assembly 607. A conical cylinder 609 is fixedly connected to the side of the blade assembly 607 away from the blade assembly 607. There is a connecting pipe 610, and an exhaust pipe 611 is fixedly connected to the side of the connecting pipe 610 near the pressing die 2. The exhaust pipe 611 is inclined downward at ten degrees from the side of the connecting pipe 610 towards the side of the pressing die 2, and there are four exhaust pipes 611. The four exhaust pipes 611 are evenly distributed above the pressing die 2. A fixing plate 612 is fixedly connected to the top of the tapered cylinder 609. The top of the fixing plate 612 is fixedly connected to the bottom of the upper mold 3. A support plate 608 is movably connected to the side of the connecting shaft 603 and the output shaft 606 away from the tapered cylinder 609. The top of the support plate 608 is fixedly connected to the bottom of the upper mold 3.

[0025] In this embodiment, when the mold is opened after pressing, the upper mold 3 moves upward, driving the connecting gear 602 to move upward. When the connecting gear 602 moves upward, it meshes with the rack 601 and rotates. When the connecting gear 602 rotates, it drives the output gear 605 to rotate faster through the synchronous gear 604. When the output gear 605 rotates, it drives the blade group 607 to rotate. When the blade group 607 rotates, it blows gas into 309, and then sprays it downward through 311. The gas blows to the bottom of the pressing punch 4, blowing off the tableware stuck to the pressing punch 4 and cooling it. The exhaust pipe 611 is inclined downward to ensure the cooling and material dropping effect. The support plate 608 and the fixing plate 612 can connect and support the entire material dropping and cooling mechanism 6.

[0026] Reference Figure 5 The detection mechanism 7 includes a support limit box 701. A movable plate 702 is movably connected inside the limit box 701. A detection head 704 is fixedly connected to the bottom end of the movable plate 702. A threaded rod 705 is threadedly connected inside the movable plate 702. A rotating wheel 706 is fixedly connected to the top end of the threaded rod 705. A slider 703 is fixedly connected to the top end of the side of the movable plate 702. A groove is provided on the side of the limit box 701 for the slider 703 to move.

[0027] The working principle of this utility model is as follows: When the tableware is pressed and formed, the raw material enters between the upper mold 3 and the pressing punch 4. At this time, when the mold is closed, the upper mold 3 moves downward. When the upper mold 3 moves downward, it drives the connecting gear 602 to move downward through the support plate 608. When the connecting gear 602 moves downward, the side of the connecting gear 602 meshes with the rack 601. Therefore, the connecting gear 602 will rotate when it moves. When the connecting gear 602 rotates, it drives the synchronous gear 604 to rotate through the connecting shaft 603. When the synchronous gear 604 rotates, it drives the output gear 605 to rotate faster. When the output gear 605 rotates, it drives the blade group 607 to rotate through the output shaft 606. When the blade group 607 rotates, it draws air into the conical cylinder 609. At this time, it will not affect the upper mold 3 and the pressing punch 4.

[0028] When the mold is opened after pressing, the upper mold 3 moves upward. At this time, the connecting gear 602 reverses, which causes the blade group 607 to reverse. When the blade group 607 reverses, air is blown into the blade group 607. The air blown into the blade group 607 will enter the exhaust pipe 611 and be blown downward through the exhaust pipe 611 on the side of the exhaust pipe 611. Therefore, when the mold is opened, if the tableware is stuck to the bottom of the pressing punch 4, the exhaust pipe 611 can blow the stuck tableware off. When the exhaust pipe 611 blows air downward, it will cool down the tableware and prevent it from being damaged by contact with the workpiece.

[0029] When monitoring the pressing process of the upper mold 3 and the pressing punch 4, if it is necessary to adjust the monitoring position, rotate the rotating wheel 706 and drive the threaded rod 705 to rotate. When the threaded rod 705 rotates, the moving plate 702 moves up and down. When the moving plate 702 moves up and down, it drives the detection head 704 to move up and down. Therefore, the detection head 704 can monitor different positions.

[0030] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
