[0001] The utility model belongs to the technical field of injection molding machines, in particular to a feed anti-blocking structure for injection molding machines. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is an industrial equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastic plastics or thermosetting plastics. Its working principle is similar to that of a syringe used for injections. Through the thrust of the screw (or plunger), the plasticized molten state (i.e. viscous flow state) is injected into the closed mold cavity, and the product is obtained after solidification and shaping. Injection molding machine is one of the important equipment that is indispensable in modern industrial production. Its high precision, high efficiency and high consistency of production characteristics make it widely used in various fields.

[0003] The problem with the existing technology is that during operation, the existing injection molding machine usually does not have an anti-blocking structure in its hopper, so that the plastic in the hopper is easily accumulated and blocked when flowing and falling, thereby affecting the working efficiency.

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown, the embodiment of the utility model provides a feed anti-blocking structure for an injection molding machine, which includes a chassis 1, an injection molding body 2 and a hopper 3. The injection molding body 2 is arranged above the chassis 1 and is fixedly connected to the chassis 1. The hopper 3 is arranged at the upper end of the injection molding body 2 and is fixedly connected to the injection molding body 2. An anti-blocking device 4 is arranged inside the hopper 3, and a transmission assembly 5 is arranged on the left side of the anti-blocking device 4. The transmission assembly 5 is fixedly connected to the injection molding body 2.

[0023] The above solution is adopted: by setting an anti-blocking device 4, it is used to prevent the plastic in the hopper 3 from being blocked, and to avoid the plastic poured into the hopper 3 from being blocked at the lower end of the hopper 3 during operation. At the same time, it also has the function of clearing the blockage.

[0024] refer to Figure 2 and Figure 3 The flow control component 41 includes a rotating rod 411, a roller 412 and a material distribution trough 413. The rotating rod 411 is arranged inside the hopper 3, and the left and right ends extend out of the hopper 3 and are rotatably connected to the hopper 3. The roller 412 is sleeved on the surface of the rotating rod 411 and fixedly connected to the rotating rod 411. There are several material distribution troughs 413, which are evenly arranged on the surface of the roller 412. The two ends of the rotating rod 411 are opposite to the two ends of the slapping component 42.

[0025] The above solution is adopted: by setting a flow control component 41, it is used to control the flow rate of the plastic in the hopper 3, and at the same time, the plastic in the hopper 3 is turned over, thereby controlling the flow and preventing blockage.

[0026] refer to Figure 2 and Figure 4 The slapping assembly 42 includes a rotating seat 421, a fixed rod 422, a clapper 423 and a tension spring 424. There are two rotating seats 421, which are respectively fixedly connected to the left and right side surfaces of the hopper 3 and correspond to the positions of the two ends of the rotating rod 411. The fixed rod 422 is arranged between the two rotating seats 421, and both left and right ends are rotatably connected to the rotating seat 421. The upper end of the clapper 423 is sleeved on the surface of the rotating rod 411 and fixedly connected to the rotating rod 411. There are two tension springs 424, which are respectively arranged on the left and right sides of the rear surface of the clapper 423. The front and rear ends of the two tension springs 424 are respectively fixedly connected to the rear surface of the clapper 423 and the front surface of the hopper 3.

[0027] The above solution is adopted: by setting a slapping component 42, which is used to slap the hopper 3, slapping the hopper 3 to generate vibration and thereby increase the flow rate of the plastic to avoid blockage, and has the function of slapping to clear the blockage.

[0028] refer to Figure 2 and Figure 4 The linkage assembly 43 includes an extrusion wheel 431 and a connecting member 432. The extrusion wheel 431 is sleeved on the surface of the rotating rod 411 extending out of one end of the hopper 3 and is fixedly connected to the rotating rod 411. The front end of the connecting member 432 is fixedly connected to the clapper 423, and the rear end corresponds to the position of the extrusion wheel 431.

[0029] The above solution is adopted: by setting a linkage component 43 to drive the slapping component 42, it has the function of linking the slapping component 42 while the flow control component 41 is running.

[0030] refer to Figure 1 and Figure 2 The transmission assembly 5 includes a motor 51, a pulley 1 52 and a pulley 2 53. The motor 51 is arranged at the lower left side of the hopper 3, and the rear end is fixedly connected to the injection molding machine body 2. The pulley 1 52 is fixedly connected to the output end of the motor 51, and the pulley 2 53 is fixedly connected to the left end of the rotating rod 411. The pulley 2 53 is connected to the pulley 1 52 through a belt.

[0031] The above solution is adopted: by setting a transmission component 5 to drive the flow control component 41, it has the function of controlling and driving the entire anti-blocking device 4.

[0032] refer to Figure 4 A rubber block 6 is provided at the lower end of the rear surface of the clapper 423 , and the rubber block 6 is fixedly connected to the clapper 423 .

[0033] The above solution is adopted: by arranging a rubber block 6 at the lower end of the rear surface of the clapper 423, the hopper 3 is directly clashed, thereby avoiding damage to the hopper 3 during the clapping process.

[0034] During use, when the plastic is poured into the hopper 3, the plastic will fall into the distributing trough 413 in the upper part of the roller 412, and some plastic will fall downward from both sides of the roller 412. The motor 51 is controlled to start, and the motor 51 drives the pulley 1 52 to rotate. While the pulley 1 52 rotates, the belt drives the pulley 2 53 to rotate through the belt. While the pulley 2 53 rotates, it drives the rotating rod 411 to rotate. The rotation of the rotating rod 411 drives the roller 412 to rotate, and the plastic in the upper part of the distributing trough 413 is rotated to the bottom and falls from the distributing trough 413. Then, the distributing trough 413 is rotated to take out the material to control the flow rate of most plastics, and at the same time, the plastic is turned over to prevent blockage. The clapper 423 is blocked by the rubber block 6, and the connecting member 432 is squeezed and released by the rotation of the extrusion wheel 431, so that the clapper 423 is driven to rotate. The rotation of the clapper 423 will rotate around the rotating seat 421 through the fixed rod 422, and the tension spring 424 will be stretched. After the extrusion wheel 431 rotates to stop squeezing the connecting member 432, the tension spring 424 will rebound and pull the clapper 423 back. At the same time, the clapper 423 drives the rubber block 6 to slap the hopper 3, and then the connecting member 432 is squeezed and released by the rotation of the extrusion wheel 431, thereby driving the clapper 423 to slap back and forth to prevent blockage.

[0035] To sum up: the injection molding machine uses a feed anti-blocking structure, which solves the problem that the existing injection molding machine usually has no anti-blocking structure in its hopper during operation, by setting a chassis 1, an injection molding body 2, a hopper 3, an anti-blocking device 4, a flow control component 41, a rotating rod 411, a roller 412, a material distribution trough 413, a slapping component 42, a rotating seat 421, a fixed rod 422, a clapper 423, a tension spring 424, a linkage component 43, an extrusion wheel 431, a connector 432, a transmission component 5, a motor 51, a pulley 1 52, a pulley 2 53 and a rubber block 6. In this way, the plastic in the hopper is easily accumulated and blocked when it flows and falls, thereby affecting the work efficiency.
