Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an automatic material unloading and conveying device for injection molding machines. Background Art

[0002] When unloading materials from the discharge port of the injection molding machine, they are usually transported manually. Since the discharge port is relatively low, workers need to bend over to operate, which is time-consuming and labor-intensive, and inefficient. Therefore, a robot is used to replace manual labor. The setting of the robot is not only costly, but also incomplete and easy to miss. The missed finished products still need to be cleaned up manually.

[0003] Therefore, how to reduce costs and improve the efficiency of removing finished products from the discharge port of the injection molding machine has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In order to solve the technical problems in the background technology, the utility model discloses an automatic material unloading and conveying device for an injection molding machine.

[0005] The utility model provides an automatic material unloading and conveying device for an injection molding machine, comprising a material conveying cylinder installed at the outlet of the injection molding machine;

[0006] A conveyor is installed below the feeding cylinder;

[0007] The feeding tube is funnel-shaped, which accurately guides the finished product to the starting position of the conveyor;

[0008] The conveyor is arranged at an angle, transporting from bottom to top, allowing workers to fill while standing upright.

[0009] When the finished product falls from the outlet of the injection molding machine, it falls accurately onto the conveyor under the guidance of the feeding barrel; because the conveyor covers the outlet of the feeding barrel, the finished product can fall completely onto the conveyor without omission, thereby improving the efficiency of taking out the finished product; the structural setting of the conveyor can reduce the filling labor intensity of the workers. Compared with the traditional manipulator, the above structure is simple in structure and low in cost.

[0010] The specific structure of the feeding cylinder is as follows: it includes a guide tube and a flow tube connected to each other; the guide tube is in a prism shape, and its expanded end is connected to the outlet of the injection molding machine; the outlet of the flow tube is located just above the starting position of the conveyor.

[0011] When the finished products fall, there will be an impact, and some of the finished products will impact the guide tube and the flow tube in turn, thereby generating a large noise. Based on this, a further improvement is that the outlet area of ​​the guide tube is smaller than the inlet area of ​​the flow tube, and the inlet of the flow tube covers the outlet of the guide tube. This arrangement can reduce the amount of finished products that hit the flow tube, thereby reducing noise.

[0012] The conveyor relies on friction to transport finished products, and the finished products are easy to slide down and accumulate at the lower part of the conveyor, thereby reducing the conveying efficiency. Based on this, further improvements are: the conveyor includes a conveyor belt; a plurality of push plates are arranged on the conveyor belt to support the finished products and push the finished products to a higher place.

[0013] Since the conveyor generates vibrations when it is working, the finished products are easy to fall outward from both sides of the conveyor. Based on this, a further improvement is that baffles are installed on both sides of the conveyor to prevent the finished products from falling out from both sides of the conveyor.

[0014] The setting of the baffle requires that the lower part of the conveyor needs to provide sufficient space for the baffle to run, so an insertion hole is set at the lower part of the conveyor; when the baffle passes over the insertion hole and the next baffle has not yet run to the insertion hole position, the finished product behind the baffle that has passed the insertion hole will fall outward from the insertion hole. Based on this, a further improvement is that a flexible baffle is installed at the starting position of the conveyor, the upper end of which is fixedly connected to the frame of the conveyor, the lower end is against the conveyor belt, and is arranged at an angle under the conveying action of the conveyor belt, and the insertion hole is blocked to prevent the finished product from falling outward from the lower end of the conveyor.

[0015] Since different injection molding machines have different outlet heights, in order to make the utility model applicable to different injection molding machines, a further improvement is that a high-end leg is installed at the high end of the conveyor, and its height is adjustable. The specific adjustment structure is: the high-end leg includes a fixed leg and a floating leg; the floating leg is inserted into the fixed leg and fixed by bolts; the floating leg is provided with a plurality of threaded holes, and different threaded holes are connected by bolts to adjust the extension length of the floating leg, thereby adjusting the height of the high-end leg.

[0025] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0026] Embodiment 1:

[0027] like Figure 1 As shown, the utility model discloses an automatic material unloading and conveying device for an injection molding machine, comprising a material feeding cylinder 1 and a conveyor 3.

[0028] like Figure 2-5 As shown, the feed barrel 1 is funnel-shaped and consists of a guide tube 4 and a flow tube 5 connected to each other; the guide tube 4 is prism-shaped, and its expanded end is connected to the outlet of the injection molding machine 2; the outlet of the flow tube 5 is located directly above the starting position of the conveyor 3.

[0029] like Figure 6 As shown, the conveyor 3 is arranged obliquely, including a conveyor belt 6, which transports the finished products from bottom to top, so that workers can fill the products at the high end of the conveyor 3 while standing upright, which can reduce the workers' filling labor intensity.

[0030] A plurality of push plates 7 are provided on the conveyor belt 6 for supporting the finished products and stably conveying the finished products to a higher place.

[0031] Baffles 8 are also installed on both sides of the conveyor 3 to prevent finished products from falling from both sides of the conveyor 3 due to vibration.

[0032] The setting of the baffle 8 requires that sufficient space be provided for the operation of the baffle 8 at the lower part of the conveyor 3, so an insertion hole is set at the lower part of the conveyor 3; when the baffle 8 passes over the insertion hole and the next baffle 8 has not yet run to the insertion hole position, the finished product behind the baffle 8 that has passed the insertion hole will fall outward from the insertion hole, so the following design is made: a flexible baffle skin 9 is installed at the starting position of the conveyor 3, the upper end of which is fixedly connected to the frame of the conveyor 3, the lower end is against the conveyor belt 6, and is arranged at an angle under the conveying action of the conveyor belt 6, and the insertion hole is blocked to prevent the finished product from falling outward from the lower end of the conveyor 3.

[0033] When the finished product falls from the outlet of the injection molding machine 2, it accurately falls onto the conveyor 3 under the guidance of the feeding cylinder 1; since the conveyor 3 covers the outlet of the feeding cylinder 1, the finished product can fall completely onto the conveyor 3 without omission, thereby improving the efficiency of taking out the finished product. Compared with the traditional manipulator, the above structure is simple in structure and low in cost.

[0034] Embodiment 2:

[0035] Compared with the first embodiment, the difference is that when the finished products fall, there will be an impact force, and some of the finished products will impact the guide tube 4 and the flow tube 5 in turn, thereby generating a large noise, so the following design is made: the outlet area of ​​the guide tube 4 is smaller than the inlet area of ​​the flow tube 5, and the inlet of the flow tube 5 covers the outlet of the guide tube 4. This arrangement can reduce the amount of finished products that impact the flow tube 5, thereby reducing noise.

[0036] Embodiment three:

[0037] Compared with the first embodiment, the difference is that a high-end support leg 10 is installed at the lower end of the high end of the conveyor 3. Figure 7 As shown, the high-end leg 10 includes a fixed leg and a floating leg 12; the floating leg 12 is inserted into the fixed leg and is locked and fixed by a bolt 13; the floating leg 12 is provided with a plurality of threaded holes, and different threaded holes are connected by bolts 13 to adjust the extension length of the floating leg 12, thereby adjusting the height of the high-end leg 10. In this way, the utility model can be applied to injection molding machines 2 with different outlet heights, and is more practical.

[0038] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
