Description

Technical Field

[0001] The utility model relates to the technical field of EPS insulation module forming technology, in particular to an EPS insulation module forming machine. Background Art

[0002] The forming of EPS insulation modules goes through several processes such as preheating, mold closing, feeding, heating, cooling, and demolding. EPS insulation modules of different volumes require different amounts of raw materials. For example, an EPS insulation module forming machine disclosed in Chinese Patent Application No. CN201920383246.X has the following specific content: When in use, first connect the cylinder to an external compressed air source, and at the same time connect the hydraulic rod and the feeding hydraulic rod to the hydraulic system. At this time, the feeding hydraulic rod drives the feeding valve to descend, so that EPS foam particles enter the inside of the mold cavity housing through the feeding pipe. When the raw materials are sufficient, the feeding valve is reset by the feeding hydraulic rod. At this time, the air inlet valve and the air outlet valve are opened simultaneously, so that the external high-temperature steam can circulate and flow through the inside of the mold cavity housing. At this time, the EPS foam particles begin to expand and extrude into shape. When the forming is completed, the hydraulic rod drives the upper turning door to open, and at the same time the cylinder works, so that the discharging push block extends forward to push the formed EPS insulation module out of the inside of the mold cavity housing. It has the following technical problems:

[0003] When producing EPS insulation modules of different volumes, different amounts of raw materials are required. It is difficult to adjust the conveying amount of the raw materials by using a cylinder to convey the raw materials. Summary of the Utility Model

[0035] The preferred specific implementation modes for implementing the present utility model are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0036] Please refer to Figures 1-6 , the present utility model provides an EPS insulation module molding machine, which includes a molding frame 100. A sealing door 110 is movably installed at the left end of the molding frame 100. A cylinder 120 for pushing out the molded EPS insulation module is installed at the right end of the molding frame 100. After the EPS insulation module is molded, the sealing door 110 is opened, and the cylinder 120 is started. The push plate installed at one end of the cylinder 120 pushes the molded EPS insulation module out from the operation port at the left end of the sealing door 110.

[0037] Please refer to Figure 1 and Figure 2 , a blanking component 001 for facilitating the feeding of raw materials into the interior of the molding frame 100 is installed at the upper end of the molding frame 100. The blanking component 001 includes a blanking hopper 200. First gears 210 are installed on the inner walls at the front and rear ends below the blanking hopper 200. In this embodiment, four first gears 210 are provided, two of which are located on the inner wall at the front end of the blanking hopper 200, and the other two are located on the inner wall at the rear end of the blanking hopper 200.

[0038] Please refer to Figure 2 and Figure 3 , a rotating shaft 211 for driving the first gear 210 to rotate is fixedly installed in the middle of the first gear 210. The other end of the rotating shaft 211 extends out of the blanking hopper 200. The other end of the rotating shaft 211 is connected to a motor 220 for controlling the rotation of the rotating shaft 211. More specifically, a limiting frame 230 for fixing the motor 220 is installed on the outer wall of the blanking hopper 200.

[0039] In this embodiment, the motor 220 is fixed to the outer side of the limit frame 230, and the output shaft of the motor 220 is fixedly connected to the rotating shaft 211. Furthermore, a gear 212 is fixedly installed at the other end of the rotating shaft 211. Among them, the two gears 212 located at the front end of the lower hopper 200 are meshed with each other, and the two gears 212 located at the rear end of the lower hopper 200 are meshed with each other, and the gears 212 are located outside the lower hopper 200. One of the two gears 212 located at the front end of the lower hopper 200 is fixedly connected to the output end of the motor 220, and one of the two gears 212 located at the rear end of the lower hopper 200 is fixedly connected to the output end of the motor 220. In this way, the front end and the rear end of the lower hopper 200 can control the rotation of the two gears 212 through a motor 220, and synchronously drive the two gears 1 210 to rotate.

[0040] Furthermore, gear 212 is located between the limit frame 230 and the outer wall of the lower hopper 200, and is accommodated in the accommodating space between the limit frame 230 and the lower hopper 200, to prevent gear 212 from being caught in debris during rotation and causing abnormal machine operation, or even scratching or pinching the employee's body and causing personal injury.

[0041] When it is necessary to control the second adjustment component 500 to move up and down, the motor 220 is started, and the motor 220 drives the gear 2 212 to rotate, so that the two gears 212 rotate in opposite directions, and synchronously drive the rotating shaft 211 to rotate, and then the rotating shaft 211 drives the two gears 1 210 in the same direction to rotate in opposite directions, so as to control the second adjustment component 500 to move up and down.

[0042] See also Figure 1 and Figure 4 The inside of the material discharging component 001 is equipped with a quantitative component 002 for controlling the amount of raw materials to be put in. The quantitative component 002 includes a limiting column 300 for limiting the raw materials. The outer wall of the limiting column 300 is arranged in abutment with the inner wall of the lower hopper 200 and the limiting column 300 is fixed on the lower hopper 200. The limiting column 300 is provided with a first material hole 310 and a second material hole 320 for the circulation of raw materials through the upper and lower surfaces, and the first material hole 310 and the second material hole 320 are arranged at intervals at the left and right ends of the inner cavity of the lower hopper 200. The raw materials put into the lower hopper 200 are blocked by the limiting column 300, so that the raw materials can only fall into the inside of the forming frame 100 through the first material hole 310 and the second material hole 320.

[0043] See also Figure 4 and Figure 5, a first adjusting component 400 for opening and closing the first material passing hole 310 and the second material passing hole 320 is movably installed in the middle of the limiting column 300. The first adjusting component 400 includes a first sealing plate 410 for opening and closing the upper ends of the cavities of the first material passing hole 310 and the second material passing hole 320. One end of the first sealing plate 410 is fixedly installed with a first connecting block 411. One end of the first connecting block 411 is connected with a first limiting ring 412 for limiting the first connecting block 411. A plurality of first bolts 413 for cooperating with the lead screw nut 430 to limit the first sealing plate 410 are installed on the edge of the first limiting ring 412, and the first bolts 413 are installed at the upper end of the lead screw nut 430, so that when the lead screw nut 430 rotates, the first sealing plate 410 is synchronously driven to rotate.

[0044] The first adjusting component 400 further includes a second sealing plate 420 for opening and closing the lower ends of the cavities of the first material passing hole 310 and the second material passing hole 320. One end of the second sealing plate 420 is fixedly installed with a second connecting block 421. One end of the second connecting block 421 is connected with a second limiting ring 422 for limiting the second connecting block 421. A plurality of second bolts 423 for cooperating with the lead screw nut 430 to limit the second sealing plate 420 are installed on the edge of the second limiting ring 422, and the second bolts 423 are installed at the lower end of the lead screw nut 430, so that when the lead screw nut 430 rotates, the second sealing plate 420 is synchronously driven to rotate.

[0045] The first adjusting component 400 further includes a lead screw nut 430 for limiting the first sealing plate 410 and the second sealing plate 420. A limiting hole 431 is formed in the middle of the lead screw nut 430.

[0046] Please refer to Figure 6 , a second adjusting component 500 for controlling the rotation of the first adjusting component 400 is installed in the middle of the first adjusting component 400. The second adjusting component 500 includes a rack 510 for cooperating with the first gear 210 to control the up and down movement of the second adjusting component 500, and the rack 510 is located at the front and rear ends of the inner cavity of the feeding hopper 200. Tooth blocks 511 for meshing with the first gear 210 are convexly provided on both the left and right sides of the rack 510.

[0047] Please refer to Figure 5 and Figure 6 , the second adjusting component 500 includes a reciprocating lead screw 520 for cooperating with the limiting hole 431 to control the rotation of the lead screw nut 430. A sliding block for sliding in the middle spiral groove of the reciprocating lead screw 520 is arranged inside the cavity of the limiting hole 431, so that when the reciprocating lead screw 520 moves up and down, the lead screw nut 430 rotates in the middle of the limiting column 300. A connecting rod 521 for limiting the rack 510 is installed at the lower end of the reciprocating lead screw 520.

[0048] Two gears 210 are respectively engaged with the tooth blocks 511 on the left and right sides of the rack bar 510. When the gear 210 rotates, the tooth block 511 is used to drive the rack bar 510 to move up and down. Under the limitation of the connecting rod 521, the reciprocating lead screw 520 moves up and down synchronously, and the reciprocating lead screw 520 moves up and down in the cavity of the limiting hole 431, so that the lead screw nut 430 drives the first sealing plate 410 and the second sealing plate 420 to rotate synchronously. When the first sealing plate 410 rotates to the upper end of the first material passing hole 310 to close the feeding port of the first material passing hole 310, the second sealing plate 420 rotates to the lower end of the second material passing hole 320 to close the discharging port of the second material passing hole 320, so that the raw material in the first material passing hole 310 moves into the inner cavity of the molding frame 100, and the raw material at the upper end of the limiting column 300 falls into the cavity of the second material passing hole 320. When the lead screw nut 430 continues to rotate, the first sealing plate 410 moves to the upper end of the second material passing hole 320, so that the raw material in the second material passing hole 320 falls into the inner cavity of the molding frame 100, and the raw material at the upper end of the limiting column 300 falls into the cavity of the first material passing hole 310. Repeating this process, the amount of raw material falling into the inner cavity of the molding frame 100 each time is kept consistent.

[0049] By controlling the number of rotation cycles of the gear 210 through the motor 220, the length of the up and down movement of the rack bar 510 can be adjusted, and further the length of the up and down movement of the reciprocating lead screw 520 in the limiting hole 431 can be adjusted. The greater the length of the up and down movement of the reciprocating lead screw 520 in the cavity of the limiting hole 431, the more rotation cycles the lead screw nut 430 has, and the more times the first sealing plate 410 and the second sealing plate 420 open and close the first material passing hole 310 and the second material passing hole 320 respectively, and the more the amount of raw material conveyed into the inner cavity of the molding frame 100. On the contrary, the amount of raw material conveyed into the inner cavity of the molding frame 100 is less, and finally the purpose of adjusting the amount of raw material conveyed is achieved.

[0050] Based on the above content and the drawings, those skilled in the art can understand and implement the present utility model. In addition, any non-creative modification made to the present utility model by those skilled in the art without creative labor still falls within the protection scope of the present utility model.
