It has the advantages of light weight, heat insulation, sound absorption, shock resistance, moisture resistance, corrosion resistance, etc. According to its cell structure, it can be divided into closed-cell, open-cell and reticulated foam plastics. After the foam plastic is produced and molded, a corresponding discharging device is needed to discharge it.

[0003] The current automatic discharging device for a plastic foam molding machine, as described in the patent with publication number CN218700718U, includes a connecting housing. An anti-accumulation mechanism is arranged inside the connecting housing. A through groove penetrating the rear end face is formed on the front end face of the connecting housing. The anti-accumulation mechanism includes a connecting shaft, and the outer surface of the connecting shaft near both ends is slidably connected to the inner wall of the through groove of the connecting housing.

[0025] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0026] Please refer to Figures 1-4 , an automatic discharging device for a plastic foam molding machine, including a conveying mechanism 1. The conveying mechanism 1 includes a belt conveyor 101. The belt conveyor 101 is arranged to convey and discharge the foam plastics that are discharged along with it when starting to work. Support columns 102 are fixedly connected to the four corners of the bottom of the belt conveyor 101. The support columns 102 can support the belt conveyor 101. Vertical plates 104 are fixedly connected to both sides of the belt conveyor 101. Adjusting screws 105 are rotatably connected inside the two groups of vertical plates 104. Sliding blocks 106 are threadedly connected to the outer sides of the two groups of adjusting screws 105. The two groups of sliding blocks 106 are respectively slidably connected to the two groups of vertical plates 104. A height limiting rod 107 is fixedly connected between the two groups of sliding blocks 106. The height limiting rod 107 can limit the height of the passing foam plastics, so as to reduce the foam plastics being discharged in a stacked manner. During the rotation of the adjusting screw 105, the sliding block 106 and the height limiting rod 107 can be driven to move up and down, so as to realize the adjustment of the height limiting height.

[0027] An isolation sleeve 108 is rotatably connected to the outer side of the height limiting rod 107. The isolation sleeve 108 can separate the height limiting rod 107 from the conveyed foam plastics, thereby reducing the probability of the height limiting rod 107 causing wear to the foam plastics. Worms 109 are fixedly connected to the upper sides of the outer parts of the two groups of adjusting screws 105. A worm 110 is meshed with one side of the two groups of worms 109. The worm 110 is rotatably connected to the two groups of vertical plates 104. The worm 110 can drive the two groups of worms 109 and the adjusting screws 105 to rotate synchronously when rotating, so as to realize the synchronous adjustment of the two groups of sliding blocks 106. A guiding mechanism 2, the guiding mechanism 2 includes a bottom plate 201 fixedly connected to one side of the bottom of the belt conveyor 101. Support plates 202 are symmetrically and fixedly connected to the bottom of the bottom plate 201. The bottoms of the two groups of support plates 202 are at the same height as the bottoms of the support columns 102. The support plates 202 can further support the bottom plate 201, thereby improving the stability of the bottom plate 201.

[0028] The top of the bottom plate 201 is symmetrically fixedly connected with a fixed plate 203, and a bidirectional screw 204 is rotatably connected between the two groups of fixed plates 203. A second stepper motor 211 is fixedly connected to one side of the fixed plate 203, and the output end of the second stepper motor 211 is fixedly connected to one end of the bidirectional screw 204. The second stepper motor 211 is configured to drive the bidirectional screw 204 to rotate when starting the work. The outer side of the bidirectional screw 204 is symmetrically threadedly connected with a connecting plate 206, and the bidirectional screw 204 is configured to drive the connecting plates 206 on both sides to move relative to or away from each other when rotating. A sliding rod 205 is symmetrically fixedly connected between the two groups of fixed plates 203, and the two groups of sliding rods 205 are slidably connected to the two groups of connecting plates 206. The configuration of the sliding rod 205 can guide the movement of the connecting plate 206. The bottoms of the two groups of connecting plates 206 are fixedly connected with right-angled trapezoidal plates 207 , and the four corners of the bottoms of the two groups of right-angled trapezoidal plates 207 are rotatably connected with belt rollers 209 . The setting of the right-angled trapezoidal plates 207 can support the belt rollers 209 .

[0029] The two groups of connecting plates 206 are symmetrically fixedly connected to the opposite sides with reinforcing rib plates 212, which are fixedly connected to the right-angled trapezoidal plates 207. The setting of reinforcing rib plates 212 can further connect and fix the connecting plates 206 and the right-angled trapezoidal plates 207, thereby improving the connection stability between the connecting plates 206 and the right-angled trapezoidal plates 207. The conveyor belt 210 is connected to the outer side of the four groups of belt rollers 209 on the same side, and the conveyor belt 210 is located at the top of the belt conveyor 101. The tops of the two groups of right-angled trapezoidal plates 207 are fixedly connected with the first stepper motor 208, and the output end of the first stepper motor 208 is fixedly connected to the belt roller 209. The first stepper motor 208 is set to drive the belt roller 209 and the conveyor belt 210 to rotate when starting the work. When rotating, the conveyor belt 210 can assist the belt conveyor 101 in conveying the foam plastic, and can also play a role in guiding and centering the foam plastic. Baffles 103 are fixedly connected to both sides of the top of the belt conveyor 101. The baffles 103 are located on one side of the conveyor belt 210. The setting of the baffles 103 can limit the foam plastic conveyed by the belt conveyor 101 to reduce the probability of the foam plastic detaching from the top of the belt conveyor 101.

[0030] In this embodiment, the belt conveyor 101 is a prior art and will not be described in detail herein.

[0031] During use, rotate the worm 110, so that when the worm 110 rotates, it can drive the two-sided worm wheels 109 and the two-sided adjusting screws 105 to rotate synchronously. When the two groups of adjusting screws 105 rotate synchronously, they can drive the two-sided sliding blocks 106 to move up and down synchronously, thereby driving the height-limiting rod 107 and the isolation sleeve 108 to move up and down accordingly, until the distance between the isolation sleeve 108 and the belt conveyor 101 is adjusted to be greater than the height of the foam plastic to be conveyed and lower than twice the height of the foam plastic to be discharged. Then, start the second stepping motor 211, so that the second stepping motor 211 can drive the bidirectional screw 204. When the bidirectional screw 204 starts to work, it can drive the two groups of connecting plates 206 and the conveyor belt 210 to move relatively, until the distance between the two groups of conveyor belts 210 is adjusted to be the same as the width of the foam plastic to be discharged. Then, start the belt conveyor 101, so that after the processed plastic foam falls onto the belt conveyor 101, it can be conveyed by the belt conveyor 101. During the conveying process, the two-sided first stepping motors 208 can be started, so that the two-sided first stepping motors 208 can drive the two-sided belt rollers 209 and the two-sided conveyor belts 210 to rotate relatively. At the same time, the rotation speed of the conveyor belt 210 is the same as the conveying speed of the belt conveyor 101. When the plastic foam passes through the bottom of the isolation sleeve 108, the isolation sleeve 108 can push down the stacked foam plastic to prevent the stacked conveying of the foam plastic. When the foam plastic passes between the two groups of conveyor belts 210, it can be centered by the guiding of the two groups of conveyor belts 210. At the same time, because the rotation speeds of the two groups of conveyor belts 210 are the same as the conveying speed of the belt conveyor 101, the two groups of conveyor belts 210 can assist in the conveying of the foam plastic.
