[0027] The automatic unloading machine 1 includes a turntable frame 1-1, a turntable 1-2 and a motor 1-3. The turntable 1-2 and the motor 1-3 are both installed on the turntable frame 1-1. The chain incoming material (the chain incoming material only includes the main chain link 7-1) is a coil, which is loaded on the turntable 1-2. The motor 1-3 drives the turntable 1-2 to rotate, thereby facilitating the chain to be transported to the next process.

[0028] The material discharging guide platform 2 includes a guide platform 2-1, a guide pulley 2-2, a guide slide 2-3, and a material discharging sensor 2-4. The guide pulley 2-2 and the guide slide 2-3 are arranged on the top of the guide platform 2-1 from left to right. The material discharging sensor 2-4 is arranged on the guide platform 2-1 at the lower side of the guide pulley 2-2, and is used to sense whether the chain of the guide pulley 2-2 has a chain, and transmit the signal to the controller 6; the guide pulley 2-2 is provided with a groove, and its width is adapted to the width of the main chain ring 7-1, and the guide slide 2-3 is transversely provided with a slide rail, and the width of the slide rail is also adapted to the width of the main chain ring 7-1. The setting direction of the slide rails in the guide pulley 2-2 and the guide slide 2-3 is consistent, so the two together constitute the slideway of the chain on the material discharging guide platform 2.

[0029] The slideway can be provided with multiple guide pulleys 2-2 according to the needs, and each slideway can be provided with multiple guide pulleys 2-2, such as Figure 5 As shown, two guide pulleys 2-2 are provided; the length of the guide rail of the guide slide 2-3 can also be set as required. The material discharge guide table 2 mainly plays a guiding role for the chain.

[0030] The controller 6 is installed on the guide stand 2-1 and is used to control the workflow of the entire equipment.

[0031] The injection molding machine 3 includes a feed brake end, an upper mold 3-1, a lower mold 3-2, and a discharge drive end, wherein the combination of the upper mold 3-1, the upper bracket 3-9 and the lower mold 3-2 is the upper mold 3-1 and the lower mold 3-2 of the central injection molding machine of the prior art. When the upper mold 3-1 and the lower mold 3-2 are closed, the injection molding machine 3 injects plastic to coat the chain to form a plug chain.

[0032] The feed brake end includes a front bottom plate 3-3, a chain cover plate 3-4, a front guide post 3-5, a side plate 3-6 and an upper cover plate 3-7; the upper cover plate 3-7 is connected to the upper die 3-1, and the front bottom plate 3-3 is connected to the lower die 3-2; the front guide post 3-5 sets the upper cover plate 3-7 on the upper part of the front bottom plate 3-3, and the front guide post 3-5 is provided with a front guide post 3-5 spring, so that the upper cover plate 3-7 is driven by the upper die 3-1 to move downward and then reset upward; the upper end of the side plate 3-6 is connected to the upper cover plate 3 -7, the lower end is connected to the chain cover 3-4, when the upper cover 3-7 moves downward, the side plate 3-6 is also driven to move downward, so that the side plate 3-6 can drive the chain cover 3-4 to move downward; a slideway for chain sliding is provided on the front end bottom plate 3-3, and a chain cover 3-4 is arranged above the slideway, so the chain moves between the chain cover 3-4 and the slideway of the front end bottom plate 3-3; a chain cover 3-4 spring is provided on the chain cover 3-4, which is used for resetting the chain cover 3-4 after it moves downward.

[0033] The discharging drive end includes a rear end bottom plate 3-8, an upper bracket 3-9, a rear guide column 3-10, a KK module 3-11, a servo motor 3-12, a material pulling cylinder 3-13, and a cylinder material pulling column; one end of the upper bracket 3-9 is connected to the upper mold 3-1, and the other end is connected to the servo motor 3-12, the rear end bottom plate 3-8 is connected to the lower mold 3-2, the rear guide column 3-10 sets the upper bracket 3-9 on the upper part of the rear end bottom plate 3-8, and the rear guide column 3-10 is provided with a rear guide column 3-10 spring, which is convenient for upper The bracket 3-9 rebounds upward; the upper bracket 3-9 is also provided with a slide bar, and the slide bar is provided with a KK module 3-11. The servo motor 3-12 drives the KK module 3-11 to slide forward and backward on the slide bar, and the KK module 3-11 drives the chain after injection molding to move along the slide bar to the discharge end; the pulling cylinder 3-13 is vertically arranged on the rear end bottom plate 3-8 through the cylinder bracket, and a cylinder pulling column is arranged at its lower end. The pulling cylinder 3-13 is connected to the air pipe (not shown in the figure), and its up and down movement is controlled by the air pipe. When the pulling cylinder 3-13 moves downward, it drives the cylinder pulling column to move downward, and the cylinder pulling column is inserted into the main chain ring 7-1 to limit it.

[0034] That is to say, both the feed brake end and the discharge drive end form floating channels that can move up and down. The feed brake end forms a feed floating channel, that is, a feed floating channel is formed between the front end base plate 3-3 and the chain cover plate 3-4, and the feed floating channel has a braking effect on the chain, while the discharge drive end forms a discharge floating channel, that is, a discharge floating channel is formed between the rear end base plate 3-8 and the upper bracket 3-9, and the discharge floating channel floats the chain and controls the discharge.

[0035] When the injection molding machine needs to inject, the pulling cylinder 3-13 moves downward, driving the upper bracket 3-9 to move downward, the upper bracket 3-9 drives the upper mold 3-1 to move downward, and the upper mold 3-1 drives the upper cover plate 3-7 at the feed brake end to move downward, thereby driving the chain cover plate 3-4 to move downward through the side plate 3-6, thereby clamping the chain between the slideway of the front bottom plate 3-3 and the chain cover plate 3-4, achieving the effect of chain braking; and the chain between the upper mold 3-1 and the lower mold 3-2 completes the injection molding process; at the same time, the cylinder pulling column at the discharge drive end is driven by the pulling cylinder 3-13 and inserted into the main chain ring 7-1. At this time, the KK module 3-11 is at the left end of the slide rod.

[0036] When the injection molding is completed, the pulling cylinder 3-13 moves upward, thereby driving the upper mold 3-1 to move upward, and then driving the chain cover 3-4 to move upward, and the brake limit of the chain at the feed brake end is removed; and the cylinder pulling column at the discharge drive end moves upward under the drive of the pulling cylinder 3-13, so that the KK module 3-11 drives the chain that has completed injection molding to move in the direction of collecting materials under the drive of the servo motor 3-12.

[0037] The structure of the receiving guide platform 4 is similar to that of the unloading guide platform 2, and the main difference is that there is no guide slide. The receiving guide platform 4 includes a receiving guide frame, a guide pulley, and an unloading sensor. The guide pulley is arranged on the top of the receiving guide frame, and the unloading sensor is arranged on the lower side of the guide pulley to detect whether there is a chain on the pulley and transmit the signal to the controller 6.

[0038] The structure of the automatic material receiving machine 5 is the same as that of the automatic material discharging machine 1 , and is used for receiving materials of the plug chain, which will not be described in detail here.

[0039] When loading, first manually pull the chain onto the unloading guide table 2. When the unloading sensor senses the chain, the automatic unloading machine automatically unloads the material. The chain is guided by the guide pulley 2-2 and the guide slide 2-3, and sent to the slideway at the feeding brake end. Through the slideway, it is sent between the upper mold 3-1 and the lower mold 3-2. The injection molding machine presses down to start injection molding. The feeding brake end has a brake positioning function for the chain, and the cylinder material-push column at the discharge drive end is inserted into the center space of the chain. When the injection molding is completed, the material-push cylinder 3-13 retracts, and the KK module 3-11 drives the material strip to the receiving guide table 4. When the receiving sensor of the receiving guide table 4 senses the chain, the automatic receiving machine 5 automatically receives the material. The entire production process is controlled by the controller 6.

[0040] The whole process of the plug chain being automatically buried in the forming mold is automatically transmitted, automatically collecting and releasing materials, without mold jamming, precise positioning production, no mold pressing, no burrs, and high production efficiency to achieve the purpose of fully automated production.
