DETAILED DESCRIPTION

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figure 1 As shown, this utility model provides an automatic detection and feeding device, including a drying mechanism 1 and an injection molding mechanism 2 arranged vertically and vertically, and a conveying pipe 3 connecting the two respectively. In this embodiment, the drying mechanism 1 and the injection molding mechanism 2 can be placed on different floors, while the conveying pipe 3 passes through the floor slab and connects the two. Similarly, the drying mechanism 1 can also be set above the injection molding mechanism 2 in the form of a fixed frame. The bottom of the drying mechanism 1 is provided with a discharge port 15 communicating with the conveying pipe 3. A control component 4 is provided between the discharge port 15 and the conveying pipe 3. The control component 4 is used to control the flow of material 5 in the drying mechanism 1, that is, to control the flow of the discharge port 15 and the conveying pipe 3. The control component 4 includes a first driving member 41 and a blocking member 42 corresponding to the discharge port 15. The output end of the first driving member 41 is connected to the blocking member 42 to control the movement of the blocking member 42 to seal or open the discharge port 15. The first driving member 41 is preferably a cylinder or a hydraulic cylinder.

[0032] Among them, a detection chamber 7 is provided between the conveying pipe 3 and the injection molding mechanism 2. The detection chamber 7 is provided with a detection component 71 for detecting the condition of the material 5 in the detection chamber 7. The detection component 71 is electrically connected to the control component 4 and cooperates to control the on and off of the conveying of the material 5.

[0033] Preferably, the conveying pipe 3 is a flexible pipe or a telescopic pipe. That is, during the up and down movement of the injection molding mechanism 2 during mold closing and opening, the setting of the flexible pipe or telescopic pipe enables the drying mechanism 1 to adapt to the changes in the up and down movement distance of at least part of the structure of the injection molding mechanism 2, and to provide a more stable feeding environment for the injection molding mechanism 2.

[0034] Before the injection molding operation begins, the material 5 is placed in the drying mechanism 1 and dried at high temperature before entering the waiting state for feeding.

[0035] After the injection molding work starts, the injection molding mechanism 2 works, the first driving part 41 in the control assembly 4 drives the blocking part 42 to move transversely so that the discharge port 15 is in communication with the conveying pipeline 3. At this time, the material 5 enters the conveying pipeline 3 under the action of gravity and is conveyed to the injection molding mechanism 2 after passing through the detection chamber 7. When the material 5 in the injection molding mechanism 2 is gradually accumulated towards the detection chamber 7, that is, when the detection assembly 71 detects that the material 5 in the detection chamber 7 is saturated, the detection assembly 71 sends an electric signal to the control assembly 4 to stop. After receiving the electric signal, the control assembly 4 drives the first driving part 41 and drives the blocking part 42 to move transversely in the opposite direction, so that the discharge port 15 is closed to block the conveying of the material 5. Correspondingly, as the injection molding work continuously and orderly proceeds, the material 5 in the detection chamber 7 moves downward, and when the detection assembly 71 detects that the detection chamber 7 lacks material 5, it will send an electric signal to the control assembly 4 to start again, and the discharge port 15 is in communication with the conveying pipeline 3 again to feed material;

[0036] By arranging the drying mechanism 1 and the injection molding mechanism 2 in a top-down manner and using gravity feeding, the feeding cost of the injection molding equipment is effectively reduced, and the conveying efficiency is high. At the same time, through the electrical connection and cooperation of the detection chamber 7, the detection assembly 71 and the control assembly 4, efficient linkage of the drying mechanism 1 and the injection molding mechanism 2 is realized, and the stability and timeliness of the conveying of the material 5 are further improved.

[0037] Specifically, the detection chamber 7 is in a cylindrical structure and the peripheral wall is made of transparent material, preferably glass or high-temperature-resistant material. Through the transparent arrangement of the peripheral wall of the detection chamber 7, workers can more intuitively judge the amount of the material 5 in the detection chamber 7, which is convenient for manual intervention in the conveying of the material 5 and troubleshooting of the feeding blockage problem.

[0038] Further, the detection assembly 71 is an infrared induction switch, which is convenient to install and has low cost, which is conducive to improving the detection stability of the detection assembly 71 and reducing the assembly cost of the detection assembly 71.

[0039] Further, since the output end of the detection chamber 7 is in communication with the injection molding mechanism 2, there may be a situation that the signal transmission of the detection assembly 71 and the control assembly 4 is not timely, which may easily cause the injection molding mechanism 2 to lack material. In order to better solve this technical problem, in the embodiment, a connecting pipe 72 is further arranged between the detection chamber 7 and the injection molding mechanism 2, and the connecting pipe 72 extends downwardly and obliquely.

[0040] Specifically, in the feeding process, when the material 5 in the injection mechanism 2 is saturated, the material 5 will continue to accumulate in the connecting pipe 72 and finally accumulate in the detection chamber 7. When the detection assembly 71 detects that the material 5 in the detection chamber 7 is saturated, the control assembly 4 is blocked to stop the delivery of the material 5. When the material 5 in the detection chamber 7 is insufficient, and when the detection assembly 71 and the control assembly 4 signal transmission are not timely, the material 5 in the connecting pipe 72 plays the role of standby material 5, further improves the cooperation fault tolerance of the control assembly 4 and the detection assembly 71, and provides a stable feeding environment for the injection mechanism 2.

[0041] Specifically, the drying mechanism 1 comprises a barrel 11 and a drying pipe 12. The top of the barrel 11 is provided with a feeding port 111 for inputting the material 5 and a pressure relief hole 112 for reducing the internal pressure of the barrel 11. One end of the drying pipe 12 is provided with a fan 13, and the other end extends into the barrel 11.

[0042] In use, the material 5 is loaded into the barrel 11 from the feeding port 111. Under the action of the fan 13, dry gas enters the inside of the barrel 11 through the drying pipe 12 and blows the material 5 to dry. The dried gas and moisture are discharged from the pressure relief hole 112.

[0043] Further, in order to effectively improve the drying capacity of the drying mechanism 1, a heater 14 for heating gas is further provided on the drying pipe 12. That is, the gas discharged from the fan 13 is heated by the heater 14 before flowing into the barrel 11, thereby further improving the drying efficiency of the drying mechanism 1.

[0044] Further, one end of the drying pipe 12 extending into the barrel 11 is provided with an exhaust head 121. The exhaust head 121 is provided with a plurality of exhaust holes 122. The diameter of the exhaust holes 122 is smaller than the diameter of the material 5 to prevent the material 5 from falling into the drying pipe 12. At the same time, the exhaust head 121 is arranged in the barrel 11 and close to one side of the discharge port 15, so that the hot gas stream discharged from the exhaust head 121 can fully contact the material 5 in the barrel 11, thereby improving the drying effect of the drying mechanism 1.

[0045] Specifically, after the injection mechanism 2 completes injection and opens the mold, an injection product 21 is formed in the mold cavity of the injection mechanism 2. The top of the injection product 21 is provided with a sprue rod 211 corresponding to an injection pipe (not shown). A material taking mechanism 6 is further arranged on one side of the injection mechanism 2 for taking out the injection product 21.

[0046] The taking mechanism 6 comprises a taking rack 61, a sliding block 62 is slidably connected to the taking rack 61, a second driving part 63 for driving the sliding block 62 to move, a clamping jaw 64 corresponding to the sprue rod 211 is arranged on the sliding block 62, after mold opening, the sliding block 62 is driven by the second driving part 63 to move transversely towards the injection molded product 21, so that the clamping jaw 64 abuts against the sprue rod 211 and clamps the sprue rod 211, after successful clamping, the second driving part 63 drives the sliding block 62 and the injection molded product 21 to move transversely in the opposite direction, so that the injection molded product 21 is demolded from the injection mechanism 2 and discharged.

[0047] Further, in the embodiment, the injection molded product 21 further comprises a main body part 212 arranged at the bottom of the sprue rod 211, the main body part 212 is in the shape of a transversely arranged strip, during discharging, the main body part 212 is in an incomplete cooling and setting state and the two ends of the main body part 212 are prone to bending deformation, which may cause quality problems of the injection molded product 21, therefore, a supporting rod 65 for supporting the bottom of the injection molded product 21 is arranged on the same side of the sliding block 62 and located at the same side of the clamping jaw 64, the supporting rod 65 is arranged below the clamping jaw 64, during discharging, the clamping jaw 64 clamps the sprue rod 211 of the injection molded product 21, the supporting rod 65 is inserted into the bottom of the injection molded product 21 and supports the injection molded product 21 to prevent the main body part 212 of the injection molded product 21 from bending deformation, thereby further improving the product yield of the injection molded product 21 and the discharging efficiency.

[0048] The utility model discloses an innovation lies in that the drying mechanism and the injection mechanism are arranged in an upper-lower corresponding mode, so that the material in the drying mechanism can be conveyed into the injection mechanism under the action of gravity, the feeding process is simple and efficient, and the production cost is effectively reduced.
