Description

Technical Field

[0001] This utility model relates to the field of mixing machine technology, and in particular to a mixing machine for injection molding of plastic cups. Background Technology

[0002] Most milk tea cups currently on the market are produced using injection molding, primarily using food-grade PP particles. Before being fed into the injection molding machine to form the plastic cups, the two-color plastic particles need to be mixed by a mixing device to ensure uniform material distribution. Traditional mixing equipment has its own power input, resulting in significant energy consumption for the mixing equipment integrated into the injection molding machine. If this mixing equipment could be modified to have no active power input, energy savings could be achieved, making it more energy-efficient and environmentally friendly. Therefore, this invention proposes a mixing machine for plastic cup injection molding production.

[0003] Chinese utility model patent CN221089602U discloses a mixing machine for cup injection molding production, including a mixing cylinder with a discharge nozzle at the bottom and an open top. An upper partition is provided inside the mixing cylinder, and two symmetrically arranged arc-shaped baffles are provided on the upper partition. Both ends of the arc-shaped baffles are connected to the mixing cylinder, forming a feed inlet between the arc-shaped baffles and the mixing cylinder. Several horizontally extending partitions are provided between the two arc-shaped baffles, with both ends of the horizontal partitions connected to the arc-shaped baffles. Several transverse feeding troughs are formed on the upper partition, arranged front-to-back and located inside the mixing cylinder between the two feed inlets. One of two adjacent transverse feeding troughs has a left opening on the arc-shaped baffle at its left end, and the other transverse feeding trough has a right opening on the arc-shaped baffle at its right end. A first diversion hole is arranged at the bottom of the transverse feeding trough. This mixing machine features no power input, energy saving and environmental protection, complete overall functions, and strong practicality.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the above-mentioned device mixes two types of plastic particles by injecting different colored plastic particles into two feed ports respectively. However, in actual use, when the operator injects plastic particles into the two feed ports respectively, some plastic particles have already begun to move into the horizontal feeding trough, resulting in poor uniformity of mixing of the two types of plastic particles and a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a mixing machine for plastic cup injection molding production.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mixing machine for injection molding of plastic cups, comprising a mixing cylinder with an open top, a stirring device provided on the side wall of the mixing cylinder, a discharge port provided at the bottom of the mixing cylinder, a partition plate provided at the upper end of the side wall of the mixing cylinder, the partition plate having evenly distributed diversion holes, baffles provided on both sides of the upper surface of the partition plate, a connecting groove provided at the lower end of the side wall of the baffle plate, a connecting plate being installed on the side walls of the two baffles that are close to each other, and a closing component for closing the connecting groove being provided on the baffle plate.

[0007] By adopting the above technical solution, when workers need to produce plastic cups, they must thoroughly mix two types of plastic particles. At this point, workers need to open the sealing component to close the connecting groove. Further, workers need to inject different colored plastic particles into both ends of the mixing drum, allowing the different colored plastic particles to gradually accumulate between the side walls of the two baffles and the inner wall of the mixing drum. Subsequently, workers need to close the sealing component, separating the first sliding plate from the connecting groove. This allows the plastic particles from both sides of the mixing drum to converge towards the center of the mixing drum through the connecting groove and flow into the mixing drum through the diversion hole, increasing the probability of the same amount of different colored plastic particles converging in the center of the mixing drum, thereby improving the uniformity of the mixed plastic particles. Furthermore, workers only need to turn on the stirring device to mix the plastic particles in the mixing drum.

[0008] Furthermore, a first sliding groove is provided on the inner top wall of the connecting groove, and a second sliding groove is provided on the upper surface of the baffle that communicates with the first sliding groove. The closing component includes a first sliding plate that is slidably disposed in the first sliding groove and a second sliding plate that is fixed to the first sliding plate. The second sliding plate is slidably connected to the second sliding groove.

[0009] By adopting the above technical solution, when the staff injects plastic particles of different colors into both ends of the mixing drum, when the staff needs to slide the second slide plate upward, multiple first slide plates can move upward simultaneously with the second slide plate, thereby separating the first slide plates from the connecting groove, so that the plastic particles can converge towards the center of the partition through the connecting groove, thereby increasing the probability that the same number of different colored plastic particles converge in the center of the mixing drum.

[0010] Furthermore, the upper surface of the second skateboard is provided with a grip to reduce the difficulty for workers to slide the second skateboard.

[0011] Furthermore, a first magnet block is embedded in the bottom surface of the first slide plate, and a second magnet block is embedded in the upper surface of the partition plate, which is directly opposite the first magnet block. The first magnet block and the second magnet block attract each other.

[0012] By adopting the above technical solution, when the staff slides the second slide down, the first slide follows the second slide down, which causes the first magnet to gradually approach and eventually attract each other to the second magnet, thereby improving the stability of the second slide and thus improving the staff's user experience.

[0013] Furthermore, a PTFE film is provided on the upper surface of the second magnet block.

[0014] By adopting the above technical solution, the sliding friction coefficient of the PTFE membrane is relatively small, thereby reducing the probability that the second magnet block will block the plastic particles when they pass through the connecting groove, thus improving the user experience for staff.

[0015] Furthermore, an inclined plate is provided on the side wall of the baffle, and the side wall of the inclined plate away from the baffle is flush with the inner wall of the mixing cylinder.

[0016] By adopting the above technical solution, the inclined plate increases the probability that plastic particles move towards the center of the mixing drum, thereby improving the user experience for staff.

[0017] Furthermore, the upper surface of the baffle is provided with a receiving groove, and a limiting piece is provided in the receiving groove. The side wall of the second slide plate is provided with a limiting groove that matches the limiting piece.

[0018] Furthermore, the upper surface of the limiting piece is provided with fixing bolts.

[0019] By adopting the above technical solution, the limiting plate reduces the probability of the second slide plate separating from the baffle, thereby improving the stability of the device. When the operator needs to install the limiting plate, the operator only needs to connect the limiting plate to the receiving groove and connect the fixing bolt to the limiting plate to keep the limiting plate stable, thereby reducing the difficulty for the operator to disassemble and assemble the limiting plate.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, when workers need to produce plastic cups, they need to thoroughly mix two types of plastic particles. At this time, workers need to open the sealing component to close the connecting groove. Further, workers need to inject different colored plastic particles into both ends of the mixing drum, allowing different colored plastic particles to gradually accumulate between the side walls of the two baffles and the inner wall of the mixing drum. Subsequently, workers need to close the sealing component, separating the first sliding plate from the connecting groove. This allows the plastic particles on both sides of the mixing drum to converge towards the center of the mixing drum through the connecting groove and flow into the mixing drum through the diversion hole, thereby increasing the probability of the same number of different colored plastic particles converging in the center of the mixing drum, thus improving the uniformity of the mixed plastic particles. Furthermore, workers only need to turn on the stirring device to mix the plastic particles in the mixing drum.

[0022] 2. In this application, when the operator injects plastic particles of different colors into both ends of the mixing drum, when the operator needs to slide the second slide plate upward, multiple first slide plates can move upward simultaneously with the second slide plate, thereby separating the first slide plates from the connecting groove, so that the plastic particles converge towards the center of the partition through the connecting groove, thereby increasing the probability that the same number of different colored plastic particles converge in the center of the mixing drum.

[0023] 3. In this application, when the staff slides the second slide down, the first slide slides down with the second slide, thereby causing the first magnet to gradually approach and eventually attract each other with the second magnet, thus improving the stability of the second slide and improving the staff's user experience.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-6 As shown in the embodiment of this application, a mixing machine for injection molding of plastic cups is disclosed, including a mixing cylinder 1, a stirring device 11, a partition 21, a connecting plate 41, a sealing component 5, a handle 6, a first magnet block 61, a second magnet block 7, a PTFE membrane 71, an inclined plate 8, a limiting piece 82, and fixing bolts 9. The upper end of the mixing cylinder 1 is open, and the stirring device 11 is disposed on the side wall of the mixing cylinder 1. The discharge port 2 is disposed at the bottom of the mixing cylinder 1. The partition 21 is a plate-shaped structure and is disposed on the upper end of the side wall of the mixing cylinder 1, and the partition 21 has evenly distributed diversion holes 3. The baffle 31 is a rectangular plate-shaped structure, and there are two baffles 31 respectively disposed on both sides of the upper surface of the partition 21, and the lower end of the side wall of the baffle 31 has a connecting groove 4. The connecting plate 41 is a plate-shaped structure, and there are multiple connecting plates 41 which are installed together on the side walls of two baffles 31 that are close to each other.

[0033] A first sliding groove 42 is formed on the inner top wall of the connecting groove 4, and a second sliding groove 43, which communicates with the first sliding groove 42, is formed on the upper surface of the baffle 31. A closing component 5 is disposed on the baffle 31 to close the connecting groove 4. The closing component 5 includes a first sliding plate 51 and a second sliding plate 52. The first sliding plate 51 is a rectangular plate structure and is slidably disposed in the first sliding groove 42. The second sliding plate 52 is a rectangular plate structure and is fixed to the first sliding plate 51, and is slidably connected to the second sliding groove 43.

[0034] When the staff injects plastic particles of different colors into both ends of the mixing drum, when the staff slides the second slide plate 52 upward, multiple first slide plates 51 will move upward simultaneously with the second slide plate 52, thereby separating the first slide plates 51 from the connecting groove 4. This allows the plastic particles to converge towards the center of the partition plate 21 through the connecting groove 4, thus increasing the probability that the same number of different colored plastic particles converge in the center of the mixing drum 1.

[0035] To reduce the difficulty for workers to slide the second slide plate 52, a handle 6 is provided on the upper surface of the second slide plate 52. The first magnet block 61 is a block structure and is embedded in the bottom surface of the first slide plate 51. The second magnet block 7 is a block structure and is embedded in the upper surface of the partition 21. The second magnet block 7 is directly opposite the first magnet block 61, and the first magnet block 61 and the second magnet block 7 attract each other.

[0036] When the staff slides the second slide plate 52 downwards, the first slide plate 51 follows the second slide plate 52 downwards, causing the first magnet 61 to gradually approach and eventually attract the second magnet 7, thereby improving the stability of the second slide plate 52 and thus improving the staff's user experience.

[0037] To improve the user experience, a PTFE film 71 is provided on the upper surface of the second magnet block 7. The PTFE film 71 has a low coefficient of sliding friction, which reduces the probability that the second magnet block 7 will block the plastic particles when they pass through the connecting groove 4, thereby improving the user experience.

[0038] The inclined plate 8 is a plate-shaped structure, which is set on the side wall of the baffle 31, and the side wall of the inclined plate 8 away from the baffle 31 is flush with the inner wall of the mixing cylinder 1. The inclined plate 8 increases the probability that the plastic particles move towards the center of the mixing cylinder, thereby improving the user experience for the operators.

[0039] The upper surface of the baffle 31 is provided with a receiving groove 81. The limiting piece 82 is a sheet-like structure and is disposed in the receiving groove 81. The side wall of the second sliding plate 52 is provided with a limiting groove 83 that matches the limiting piece 82. The fixing bolt 9 is disposed on the upper surface of the limiting piece 82 and is used to fix the limiting piece 82.

[0040] The limiting plate 82 reduces the probability of the second slide plate 52 separating from the baffle 31, thereby improving the stability of the device. When the operator needs to install the limiting plate 82, the operator only needs to connect the limiting plate 82 to the receiving groove 81 and connect the fixing bolt 9 to the limiting plate 82 to keep the limiting plate 82 stable, thereby reducing the difficulty for the operator to disassemble and install the limiting plate 82.

[0041] The operating principle of the mixing machine for plastic cup injection molding in this embodiment is as follows: When the operator needs to produce plastic cups, they need to thoroughly mix two types of plastic particles. At this time, the operator needs to open the sealing component 5 to close the connecting groove 4. Further, the operator needs to inject different colored plastic particles into both ends of the mixing drum, allowing different colored plastic particles to gradually accumulate between the side walls of the two baffles 31 and the inner wall of the mixing drum. Subsequently, the operator needs to close the sealing component 5, separating the first sliding plate 51 from the connecting groove 4. This allows the plastic particles on both sides of the mixing drum 1 to converge towards the center of the mixing drum 1 through the connecting groove 4 and flow into the mixing drum through the diversion hole 3, thereby increasing the probability of the same number of different colored plastic particles converging in the center of the mixing drum 1, thus improving the uniformity of the mixed plastic particles. Further, the operator only needs to turn on the stirring device 11 to mix the plastic particles in the mixing drum 1.

[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
