Description

Technical Field

[0001] The utility model belongs to the technical field of plastic color mixing machines, and particularly relates to an automatic feeding device for a plastic color mixing machine. Background Art

[0002] The process of feeding the plastic color mixer involves feeding plastic pellets of different colors or types into the machine, and then mixing them evenly together by stirring or mixing, mixing plastic pellets of different colors or types together to create plastic products that meet specific needs.

[0003] At present, when loading plastic color mixers, usually the bagged plastic particles are manually moved to the plastic color mixer, and the packaging bags are opened before feeding. Since general plastic color mixers are relatively high, manual feeding requires the plastic particles to be lifted, and the unpacking and feeding process takes a certain amount of time. During this time, the plastic particles need to be continuously lifted. If the operator makes an operating error or has poor physical strength, the plastic particles will be spilled or transferred into the plastic color mixer together with the packaging bags, reducing the feeding efficiency of the plastic particles. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic feeding device for a plastic color mixer, which can place plastic particles at a lower position and use a cutting component to cut the packaging bag, so as to facilitate the conveying of the plastic particles to the plastic color mixer and improve the feeding efficiency.

[0007] The cutting assembly includes a connecting plate arranged in the inner cavity of the movable cylinder, the side wall of the connecting plate is equipped with a blade, the side wall of the connecting plate away from the blade is fixedly connected to a movable rod, the other end of the movable rod passes through the movable cylinder and is movably connected to it, the other end of the movable rod is fixedly connected to a pressure plate, and the side wall of the movable rod is equipped with a spring.

[0011] A shielding curtain is movably connected to both sides of the movable cylinder in the through slot, and two ends of the shielding curtain are fixedly connected to the movable cylinder and the side wall of the through slot respectively.

[0012] The technical effects achieved by this utility model are:

[0013] The utility model discloses an automatic feeding device for a plastic color mixing machine. Through the mutual cooperation among a mixing box, a feeding hopper, a conveying pipe, a mounting plate and a cutting component, an operator does not need to lift the plastic particles during feeding, but can directly place the plastic particles together with the packaging bag on the filter plate, and use the cutting component to cut the packaging bag to make the plastic particles fall into the feeding hopper, and cooperate with the spiral blade to feed the materials, which effectively reduces the feeding accidents caused by fatigue of traditional manual lifting, thereby improving its feeding efficiency.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-Figure 5 As shown, an automatic feeding device for a plastic color mixing machine includes a mixing box 1 and a feeding hopper 2. A feeding barrel 3 is fixedly connected to the side wall of the feeding hopper 2, and the feeding barrel 3 is communicated with the mixing box 1. A spiral blade 4 is rotatably connected in the feeding barrel 3. A filter plate 5 is fixedly connected to the inner wall of the feeding hopper 2 near the top, and a mounting plate 6 is fixedly connected to the top end face of the feeding hopper 2. The mounting plate 6 is U-shaped, and two through grooves 7 are symmetrically provided on the side wall of the mounting plate 6. A movable barrel 8 is slidably connected in the through groove 7, and the side wall of the movable barrel 8 close to the feeding hopper 2 is open, and a cutting component is provided in the inner cavity of the movable barrel 8.

[0023] Among them, the mixing method of the mixing box 1 and the driving method of the spiral blade 4 are both existing mature technologies, so they are not described in detail in this solution. The main focus of this solution is on convenient loading.

[0024] like Figure 3 and Figure 5 As shown, the cutting assembly includes a connecting plate 9 arranged in the inner cavity of the movable cylinder 8, the side wall of the connecting plate 9 is equipped with a blade 10, the side wall of the connecting plate 9 away from the blade 10 is fixedly connected to a movable rod 11, the other end of the movable rod 11 passes through the movable cylinder 8 and is movably connected thereto, the other end of the movable rod 11 is fixedly connected to a pressure plate 13, and the side wall of the movable rod 11 is equipped with a spring 12.

[0025] Among them, the installation method of the blade 10 and the connecting plate 9 can adopt other detachable methods such as bolts and clamping to facilitate the replacement of the blade 10; and the movement of the blades 10 on both sides can be controlled simultaneously according to actual conditions to cut both sides of the packaging bag at the same time, thereby accelerating the falling speed of the plastic particles, and by setting the filter plate 5, the packaging bag can be prevented from falling into the feed hopper 2 and causing entanglement of the spiral blade 4.

[0026] like Figure 5 As shown, movable wheels 14 are respectively installed on the upper and lower side walls of the movable cylinder 8, and limiting grooves 15 are respectively provided on the upper and lower side walls of the through slot 7, and the movable wheels 14 are movably connected to the limiting grooves 15. The movable wheels 14 can limit the blade 10 on the one hand, and reduce the friction between the movable cylinder 8 and the through slot 7 on the other hand, so that the blade 10 can cut the packaging bag more smoothly.

[0027] like Figure 3 As shown, the top surface of the mounting plate 6 is fixedly connected with a fence 16. The fence 16 is U-shaped and is mainly used to protect the plastic particles to prevent the packaging bags from falling or falling when they are placed.

[0028] like Figure 5 As shown, two protective pads 17 are symmetrically fixedly connected to the inner wall of the movable cylinder 8 near the opening.

[0029] A shielding curtain 18 is movably connected to both sides of the movable cylinder 8 in the through groove 7, and two ends of the shielding curtain 18 are fixedly connected to the movable cylinder 8 and the side wall of the through groove 7 respectively.

[0030] Specifically, the protective pad 17 and the shielding curtain 18 mainly play the role of shielding plastic particles. On the one hand, they prevent the plastic particles from splashing into the through groove 7 or the movable cylinder 8 during the falling process when the packaging bag is cut, and on the other hand, they reduce the waste caused by the plastic particles flowing to the outside.

[0031] The working principle of the utility model is as follows: when it is necessary to feed the plastic particles, the plastic particles are first packaged and placed on the filter plate 5, and then the pressing plate 13 is pressed to drive the blade 10 to be inserted into the packaging bag, while the spring 12 is compressed, and then the pressing plate 13 is pushed to drive the blade 10 to move through the movable cylinder 8, so that the blade 10 cuts through the packaging bag, making it easy to shake the plastic particles into the feed hopper 2, and then the feeding cylinder 3 is operated by an external motor to transport the plastic particles into the mixing box 1, and plastic particles of different colors are mixed, which effectively reduces the feeding accidents caused by fatigue of traditional manual lifting, thereby improving its feeding efficiency.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
