Technical Field

[0001] This utility model relates to the field of food processing technology, and more specifically, it relates to a multifunctional head liquid injection device. Background Technology

[0002] A liquid injection device is a device used to inject liquid material into another material. Its injection head varies depending on the application and is commonly used in industries such as pharmaceuticals, food, and chemicals.

[0003] In food processing, liquid injection devices are frequently used to dispense materials. However, the current method of replacing injection heads usually involves removing them separately and then replacing them, which is cumbersome. Furthermore, the replaced injection heads are easily lost. In addition, traditional injection devices generally use injection heads to draw up materials and then inject them, which is not convenient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multifunctional liquid injection device for injection heads that can improve the efficiency of injection head replacement and the feeding efficiency of injection device.

An injection cylinder is fixedly connected to the top of each support plate. A protective shell is fixedly connected to the bottom left side of the injection cylinder. A worm gear is rotatably connected to the inner wall of the bottom of the protective shell. A worm wheel is meshed with the outer wall of the worm gear. A rotating rod is fixedly connected to the inner wall of the worm wheel. A connecting plate is fixedly connected to the left end of the rotating rod. Several distribution plates are fixedly connected at equal intervals to the outer wall of the connecting plate. Several injection heads are fixedly connected to the left end of each distribution plate. A left connecting pipe is fixedly connected to the right end of each distribution plate.

[0008] The present invention is further configured such that: a feed pipe is fixedly connected to the top left side of the injection cylinder, and a valve is provided at the bottom of the feed pipe.

[0009] The present invention is further configured such that: a movable block is slidably connected to the top right side of the base plate, and a cylinder is fixedly connected to the top of the movable block.

[0010] The present invention is further configured such that: a push plug is fixedly connected to the left end of the telescopic part of the cylinder, and the outer wall of the rubber plug of the push plug is slidably connected to the inner wall of the injection cylinder.

[0011] The present invention is further configured such that: the inner wall of the movable block is threadedly connected to a threaded rod, and the outer walls on both sides of the threaded rod are rotatably connected to fixed blocks, and the bottom ends of the fixed blocks are fixedly connected to the top right side of the base plate.

[0012] The present invention is further configured such that: a right connecting pipe is fixedly connected to the middle of the left end of the syringe, and a sealing ring is fixedly provided on the outer wall of the right connecting pipe.

[0014] The advantages of this utility model are:

[0015] Several injection components are arranged together. When the injection head needs to be replaced, the worm gear is rotated to drive the worm wheel to rotate, which in turn drives the distribution plate to rotate. When the required injection head reaches the guide rail, the mounting ring is rotated to connect the left and right pipes. The sealing ring is used to enhance the sealing performance, which enables the replacement of the injection head. This facilitates the dispensing of materials into different materials or containers and is suitable for a variety of liquid materials, improving the material dispensing efficiency.

[0016] By placing the feed pipe on the top left side of the injection cylinder, opening the valve during feeding allows the cylinder to move the pusher to the right, drawing in the material and shortening the feeding time. The position of the cylinder can also be adjusted by rotating the threaded rod to move the moving block to the right, allowing the pusher to be completely pulled out of the inner wall of the injection cylinder for easy replacement and cleaning.

The sealing is strengthened by the sealing ring 19, so that the injection head 11 can be replaced. It is suitable for a variety of liquid materials. In addition, by setting the feed pipe 8 on the top left side of the injection cylinder 2, the valve 9 is opened when feeding, and the cylinder 3 drives the push plug 22 to move to the right to suck up the material. The position of the cylinder 3 can be adjusted by rotating the threaded rod 4 to drive the moving block 5 to move to the right, so as to completely pull the push plug 22 out of the inner wall of the injection cylinder 2 for easy replacement and cleaning.
