Description

Technical Field

[0001] The invention relates to the technical field of table spoon production, in particular to a disposable and degradable table spoon production device. Background Art

[0002] Degradable plastic refers to plastic materials that can be decomposed by microorganisms in the natural environment under certain conditions and can be degraded into non-toxic and harmless substances. Compared with traditional plastics, degradable plastics exist in the environment for a shorter time and can reduce the impact on the environment. With the enhancement of people's environmental awareness and the increasingly prominent problem of plastic pollution in the surrounding environment, the market prospects for degradable tableware are very broad. Especially for industries such as catering, they use more degradable tableware. Although most industries use more disposable degradable tableware, restaurants and other places will also choose to provide non-disposable degradable tableware for customers to use. Compared with disposable degradable tableware, non-disposable degradable tableware can be recycled multiple times in an economical environment, effectively extending its service life, thereby reducing the waste of raw material resources.

[0003] The tableware used for holding food and facilitating eating is made of biodegradable raw materials including bamboo fiber and polylactic acid. Bamboo fiber is made from bamboo, which is fiberized by chemical or mechanical treatment to obtain cellulose fiber. The bamboo fiber is combined with polylactic acid to form a mixture for a biodegradable table spoon. The biodegradable mixture is then added to an injection molding machine, which melts the biodegradable mixture and injects it into a molding mold. When the melted biodegradable mixture fills the molding mold, the cooling system is controlled to cool and solidify the product in the molding mold, thereby obtaining the desired biodegradable plastic table spoon.

[0004] The existing injection mold for dinner spoons is inlaid with multiple mold cavities in a circular array, and each mold cavity can be injection-molded to form a dinner spoon. The circular array of plastic dinner spoons can effectively utilize the space of the injection mold and improve the manufacturing efficiency of the finished dinner spoons. The handles of the multiple dinner spoons in the circular array are interconnected, which makes it convenient to take out all the dinner spoons in the mold after injection molding. However, these redundant connecting parts need to be removed separately later and the dinner spoons need to be cut off before packing. This undoubtedly greatly affects the production efficiency of degradable dinner spoons and increases work intensity. In view of this, we propose a disposable degradable dinner spoon production device to solve the above problems. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a disposable and degradable dinner spoon production device, which has the effect of cutting off the connecting part of the spoon handle before the finished dinner spoon is demoulded and collecting it separately.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a disposable degradable dinner spoon production device, comprising an injection molding machine body, an injection molded part, a first mold body and a second mold body, wherein a plurality of mold cavities are opened on the surface of the second mold body, and the second mold body comprises an outer mold body and an inner mold body, wherein;

[0007] The inner mold body is in a truncated cone shape, a mounting groove is provided inside the inner mold body, a cutting assembly is provided inside the mounting groove, the cutting assembly comprises a first electric push rod fixedly installed on the inner wall of the mounting groove, a push plate is fixedly installed on the output end of the first electric push rod, a connecting groove connected to the mounting groove is also provided on the surface of the inner mold body, a cutting knife extending into the connecting groove is fixedly installed on the side of the push plate away from the first electric push rod, a collecting box is fixedly installed on one side of the second mold body, a first cylinder is fixedly installed on the inner wall of the collecting box, and the output end of the first cylinder is fixed to the inner mold body;

[0008] The surface of the injection molding machine body is also provided with a collecting groove for collecting dropped dinner spoon molds.

[0009] Furthermore, the flow channels on the surfaces of the outer mold body and the inner mold body are connected together, and the side of the cutter away from the push plate is flush with the inner bottom wall of the flow channel.

[0010] Furthermore, a sealing gasket is fixedly mounted on the inner wall of the connecting groove, and the cutting knife is slidably connected to the inner wall of the sealing gasket.

[0011] Furthermore, the connecting groove and the cutting knife are both arranged in an annular shape, and the inner wall of the outer mold body on one side close to the inner mold body is in a truncated cone shape.

[0012] Furthermore, the outer mold body is provided with an annular groove inside, and a demoulding component for improving demoulding efficiency is provided inside the groove.

[0013] Furthermore, the demoulding assembly includes a second electric push rod fixedly installed inside the slot, a movable plate is fixedly installed on the output end of the second electric push rod, and a plurality of top film rods are fixedly installed on the side of the movable plate away from the output end of the second electric push rod.

[0014] Furthermore, the top film rod extends into the interior of the mold cavity, and one end of the top film rod away from the movable plate is flush with the inner wall of the mold cavity.

[0015] Furthermore, a box door is hinged on the surface of the collection box, and an observation glass is embedded on the surface of the box door.

[0016] Furthermore, a collecting door is hingedly connected to the surface of the injection molding machine body and located outside the collecting tank. A driving member for driving the first mold body to move toward the second mold body is also provided on the surface of the injection molding machine body.

[0017] Compared with the prior art, the present invention provides a disposable and degradable table spoon production device, which has the following beneficial effects:

[0018] 1. The disposable degradable spoon production device divides the second mold body into an outer mold body and an inner mold body. After the degradable spoon is cooled and formed, the first electric push rod drives the cutter to cut the connecting part at the handle of the spoon. After cutting, the first cylinder automatically moves the inner mold body to the inside of the collection box. At this time, the formed connecting part will slide into the inside of the collection box for separate collection. After the first mold body is separated from the second mold body, the spoon mold will fall into the inside of the collection tank for collection, thereby completing the cutting and separate collection of the spoon and its connecting part, reducing the work intensity of the staff to cut the connecting part separately, and improving the production efficiency of the spoon.

[0019] 2. The disposable biodegradable spoon production device starts the second electric push rod to drive the ejector rod to move into the mold cavity through the demoulding component. The ejector rod can eject the cooled and formed spoon, making it less likely to get stuck in the mold cavity, thereby improving the demoulding efficiency of the spoon.

[0020] 3. The disposable degradable dinner spoon production device ensures the flatness and sealing of the flow channels on the surfaces of the inner mold body and the outer mold body by arranging a sealing gasket inside the connecting groove, so that the molten material is not easy to deviate from the flow channel from the connecting groove, thereby ensuring the integrity of the dinner spoon mold.

The surface of the second mold body 4 is provided with a plurality of mold cavities 5. The second mold body 4 includes an outer mold body 401 and an inner mold body 402.

[0031] It is worth noting that the injection molding machine body 1 is an injection molding machine in the prior art, and the injection molded part 2 , the first mold body 3 and the second mold body 4 are all components of the injection molding machine body 1 .

[0032] See also Figure 3 , Figure 4 and Figure 5 The inner mold body 402 is truncated cone-shaped, and a mounting groove 6 is provided inside the inner mold body 402. A cutting assembly is provided inside the mounting groove 6. The cutting assembly includes a first electric push rod 7 fixedly installed on the inner wall of the mounting groove 6. A push plate 8 is fixedly installed on the output end of the first electric push rod 7. A connecting groove 21 connected to the mounting groove 6 is also provided on the surface of the inner mold body 402. A cutter 9 extending into the connecting groove 21 is fixedly installed on the side of the push plate 8 away from the first electric push rod 7. A collecting box 10 is fixedly installed on one side of the second mold body 4. A first cylinder 11 is fixedly installed on the inner wall of the collecting box 10. The output end of the first cylinder 11 is fixed to the inner mold body 402. A collecting groove 19 for collecting spoon molds that fall off is also provided on the surface of the injection molding machine body 1.

[0033] In addition, by dividing the second mold body 4 into an outer mold body 401 and an inner mold body 402, after the degradable dinner spoon is cooled and formed, the first electric push rod 7 drives the cutter 9 to cut the connecting part at the handle of the dinner spoon. After the cutting is completed, the first cylinder 11 is started to drive the inner mold body 402 to move toward the inside of the collection box 10. At this time, the cut connecting part will fall into the inside of the collection box 10 to complete the collection, and then the first cylinder 11 will drive the inner mold body 402 to reset, and at the same time, the driving member drives the first mold body 3 and the second mold body 4 to separate, and most of the formed degradable dinner spoons will fall into the inside of the collection tank 19, thereby completing the cutting and separate collection of the dinner spoon and its connecting part, reducing the workload of the staff in cutting the connecting part alone, and improving the production efficiency of the dinner spoon.

[0034] In addition, the flow channels on the surfaces of the outer mold body 401 and the inner mold body 402 are connected together, and the side of the cutter 9 away from the push plate 8 is flush with the inner bottom wall of the flow channel.

[0035] See also Figure 6 In this embodiment, a sealing gasket 16 is fixedly mounted on the inner wall of the connecting groove 21 , and the cutter 9 is slidably connected to the inner wall of the sealing gasket 16 .

[0036] Among them, by arranging a sealing gasket 16 inside the connecting groove 21, the flatness and sealing of the flow channels on the surfaces of the inner mold body 402 and the outer mold body 401 are ensured, so that the molten material is not easy to deviate from the flow channel from the connecting groove 21, thereby ensuring the integrity of the spoon mold.

[0037] In this embodiment, the connecting groove 21 and the cutter 9 are both annularly arranged, and the interior of the outer mold body 401 is also provided with an annularly arranged slot 12, and the interior of the slot 12 is provided with a demoulding component for improving demoulding efficiency.

[0038] The inner wall of the outer mold body 401 on one side close to the inner mold body 402 is in a truncated cone shape, thereby facilitating the cut connecting part to slide into the interior of the collection box 10 .

[0039] See also Figure 7 In this embodiment, the demolding assembly includes a second electric push rod 13 fixedly installed inside the groove 12, a movable plate 14 is fixedly installed at the output end of the second electric push rod 13, and a plurality of top film rods 15 are fixedly installed on the side of the movable plate 14 away from the output end of the second electric push rod 13.

[0040] The top film rod 15 extends into the interior of the mold cavity 5 , and one end of the top film rod 15 away from the movable plate 14 is flush with the inner wall of the mold cavity 5 .

[0041] In addition, by setting up the demolding assembly, the second electric push rod 13 is started to drive the top film rod 15 to move into the mold cavity 5. The top film rod 15 can be used to push out the cooled and formed dinner spoon, making it less likely to get stuck in the mold cavity 5, thereby improving the demolding efficiency of the dinner spoon.

[0042] In this embodiment, a box door 17 is hinged on the surface of the collection box 10, and an observation glass 20 is embedded on the surface of the box door 17. A collection door 18 is also hinged on the surface of the injection molding machine body 1 and located outside the collection tank 19. The surface of the injection molding machine body 1 is also provided with a driving component for driving the first mold body 3 to move toward the second mold body 4.

[0043] The cut connecting parts can be cleaned by opening the box door 17, and the demoulding spoons can be collected by opening the collection door 18.

[0044] In addition, the observation glass 20 is provided to facilitate the staff to observe the collection of waste materials at the connection of the spoon inside the collection box 10, so that the staff can clean it up in time.

[0045] When the present embodiment is in use, the first mold body 3 and the second mold body 4 are fitted together by the driving member, and the molten material is injected into the mold cavity 5 on the surface of the second mold body 4 through the injection molding member 2. After the molten material is cooled and formed, the first electric push rod 7 is started to cut the connecting part at the handle of the dinner spoon. After the cutting is completed, the first cylinder 11 is started to drive the inner mold body 402 to move to the inside of the collection box 10. At this time, the cut connecting part will fall into the inside of the collection box 10 to be collected, and then the inner mold body 402 is reset by the first cylinder 11. At the same time, the first mold body 3 and the second mold body 4 are driven by the driving member. The molded body 4 is separated, and most of the molded biodegradable spoons will fall into the collecting tank 19. By starting the second electric push rod 13, the top film rod 15 is driven to move toward the inside of the mold cavity 5. The cooled and molded spoons can be pushed out by the top film rod 15, so that they are not easily stuck in the mold cavity 5, thereby improving the demoulding efficiency of the spoons. After the production work is completed, the box door 17 can be opened to clean the cut connecting parts, and the collection door 18 can be opened to collect the demoulded spoons, thereby reducing the workload of the staff for cutting the connecting parts alone and improving the production efficiency of the spoons.
