Description

Technical Field

[0001] The present application relates to the technical field of foam board processing equipment, and in particular to a foam board forming equipment. Background Art

[0002] In the process of rapid social development, the use of foam boards has also increased significantly; then the molding work of foam board production has also increased dramatically, and the technology of foam board foaming molding equipment also needs to be improved during use, which can not only meet the foaming molding needs of many foam boards, but also deal with various problems that arise in the molding and foaming work of foam boards.

[0003] The existing molding equipment includes a frame and a mold installed on the frame. The mold has a mold cavity inside and a material pipe for adding material to the mold cavity is installed on the mold. When the equipment is working, the material pipe adds material to the mold cavity and then heats the mold cavity to foam the material inside the mold cavity to form a foam board.

[0004] However, during the foaming process of the material in the mold cavity, the material may partially enter the discharge port of the material pipe; and after the foam board in the mold cavity is demolded, it may remain in the material pipe, causing the discharge port of the material pipe to be partially blocked, thereby affecting the speed of feeding the material into the mold cavity through the material pipe. Utility Model Content

[0005] Based on this, the present application provides a foam board forming device that maintains the speed of feeding the material into the mold cavity.

[0006] The foam board forming equipment provided in this application adopts the following technical solutions:

[0008] By adopting the above-mentioned technical solution, after using the equipment to make foam boards, the connection between the material pipe and the connecting pipe is cancelled by disassembling parts. At this time, the rotating pipe can be rotated so that the pipe mouth of the connecting pipe is exposed to the outside world, so that the staff can clean the pipe mouth of the connecting pipe and reduce the blockage in the connecting pipe, thereby increasing the speed of feeding the material pipe into the mold cavity.

[0009] Optionally, the connection position between the rotating rod and the mold is located below the connecting tube, and the mold is provided with a first positioning plate and a second positioning plate. When the rotating rod is in contact with the first positioning plate, the discharge port of the material tube and the feed port of the connecting tube are arranged opposite each other; when the rotating rod is in contact with the second positioning plate, the discharge port of the material tube and the feed port of the connecting tube are arranged offset.

[0010] By adopting the above-mentioned technical solution, when the rotating rod is abutted against the first positioning plate, the discharge port of the material pipe and the feed port of the connecting pipe are arranged opposite each other, so that the staff can connect the material pipe and the connecting pipe through the disassembly parts; when the rotating rod is abutted against the second positioning plate, since the connection point of the rotating rod and the mold is located below the connecting pipe, the rotating rod can abut against the second positioning plate by its own weight, reducing the situation where the rotating rod rotates freely when cleaning the pipe wall of the connecting pipe, thereby increasing the stability of the material pipe mounted on the second positioning plate.

[0011] Optionally, a torsion spring is provided between the rotating rod and the mold, and the elastic force of the torsion spring is used to drive the rotating rod to abut against the second positioning plate under normal conditions.

[0012] By adopting the above technical solution and setting a torsion spring, the rotating rod can be normally abutted against the second positioning plate, further increasing the stability of the material pipe mounted on the second positioning plate and reducing the situation where the rotating rod rotates freely when cleaning the pipe wall of the connecting pipe.

[0013] Optionally, the disassembly part includes a sleeve, the inner wall of the sleeve is provided with a first threaded portion, the outer wall of the material pipe is provided with a second threaded portion, and the outer wall of the connecting pipe is provided with a third threaded portion, and the first threaded portion is used to cooperate with the second threaded portion and the third threaded portion.

[0014] By adopting the above-mentioned technical solution, the first threaded portion of the inner wall of the sleeve cooperates with the second threaded portion of the outer wall of the material pipe and the third threaded portion of the connecting pipe at the same time, so that the connecting pipe and the material pipe can be connected, so that the material in the material pipe can pass into the mold cavity through the connecting pipe.

[0015] Optionally, a fourth threaded portion is provided on the outer wall of the connecting pipe, a mounting groove communicating with the mold cavity is provided in the mold cavity, a fifth threaded portion is provided on the inner wall of the mounting groove, and the fourth threaded portion and the fifth threaded portion cooperate with each other.

[0017] Optionally, the material pipe is equipped with a feed pipe and two groups of blowing pipes connected thereto, wherein the air outlet of one group of blowing pipes is arranged opposite to the feed inlet of the feed pipe, and the other group of blowing pipes is connected to one end of the material pipe away from the connecting pipe.

[0018] By adopting the above-mentioned technical solution, the air blowing pipe arranged opposite to the feed port of the feed pipe can ensure that the material entering the feed pipe can be evenly blown into the mold cavity, reducing the accumulation and blockage of the material in the material pipe, and ensuring the continuity and efficiency of the production process; and by installing another air blowing pipe at the end of the material pipe away from the mold, it is further ensured that all the material in the material pipe is pushed into the mold cavity, ensuring the purity of the material in the next operation.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a foam board forming device.

[0033] Reference Figure 1 A foam board forming device includes a frame 1, a material pipe 2, a mold 3 and a driving assembly 4. The material pipe 2 is used to add material to the mold 3; the mold 3 includes a left mold 31 and a right mold. The left mold 31 is fixed on the frame 1, and the frame 1 is provided with a slide rail 11. The right mold is slidably installed on the slide rail 11. The driving assembly 4 is configured as a first cylinder. The first cylinder is installed on the frame 1. The movable plug of the first cylinder is connected to the right mold. By driving the cylinder, the right mold can be moved closer to / away from the side of the left mold 31.

[0034] Reference Figure 2 and Figure 3The left mold 31 has a first cavity 33, and the right mold 32 has a second cavity 34. When the left mold 31 and the right mold are in contact with each other, the first cavity 33 and the second cavity 34 are connected to form a mold cavity 35; the inner walls of the first cavity 33 and the second cavity 34 are coated with a polyethylene coating. The polyethylene coating can reduce the adhesion between the material and the inner wall of the mold cavity 35, and reduce the damage to the product when the foam board is demolded, thereby improving the demolding efficiency.

[0035] Reference Figure 3 The first cavity 33 and the second cavity 34 are both provided with an ejection groove 36 on the side away from each other, and an ejection rod 5 is movably installed in the ejection groove 36; the frame 1 is installed with a second cylinder 51, and the movable plug of the second cylinder 51 is connected to all the ejection rods 5 of the left mold 31 / right mold; after the foam board is formed in the mold cavity 35, the ejection rod 5 can be used to eject the foam board from the first cavity 33 and the second cavity 34, thereby further improving the demolding efficiency of the foam board.

[0036] Reference Figure 3 A mounting groove 37 is provided on the side of the left film away from the right mold, and the mounting groove 37 is communicated with the second chamber 34; a connecting pipe 6 is provided in the mounting groove 37, and a fourth threaded portion 61 is provided on the outer wall of the connecting pipe 6, and a fifth threaded portion for cooperating with the fourth threaded portion 61 is provided on the inner wall of the mounting groove 37; the cooperation between the fourth threaded portion 61 and the fifth threaded portion can enable the connecting pipe 6 to be detachably installed on the left mold 31, so as to facilitate the inspection and replacement of the connecting pipe 6, thereby improving the service life of the connecting pipe 6.

[0037] Reference Figure 4 A rotating rod 7 is rotatably installed on the outer wall of the left mold 31, and the rotating rod 7 is connected to the left film through a rotating shaft 74; the rotating shaft 74 is located below the connecting tube 6, and the end of the rotating rod 7 away from the rotating shaft 74 is connected to the material tube 2; the left mold 31 is provided with a first positioning plate 71 and a second positioning plate 72; when the rotating rod 7 abuts against the first positioning plate 71, the discharge port of the material tube 2 and the feed port of the connecting tube 6 are arranged opposite each other, and at this time the material tube 2 is connected to the connecting tube 6 through the disassembly part 8; when the rotating rod 7 abuts against the second positioning plate 72, the discharge port of the material tube 2 and the feed port of the connecting tube 6 are staggered.

[0038] Reference Figure 4 A torsion spring 73 is provided between the rotating rod 7 and the left mold 31. The torsion spring 73 is sleeved on the outer wall of the rotating shaft 74. The elastic force of the torsion spring 73 is used to drive the rotating rod 7 to abut against the second positioning plate 72 under normal conditions; thereby increasing the stability of the material tube 2 mounted on the second positioning plate 72 and reducing the situation where the rotating rod 7 rotates freely when the tube wall of the connecting tube 6 is cleaned.

[0039] Reference Figure 4The disassembly part 8 includes a sleeve, a first threaded portion is provided on the inner wall of the sleeve (not shown in the figure), a second threaded portion 81 is provided on the outer wall of the material pipe 2, and a third threaded portion 82 is provided on the outer wall of the connecting pipe 6. The first threaded portion is used to cooperate with the second threaded portion 81 and the third threaded portion 82. In this embodiment, the thread direction of the third threaded portion of the connecting pipe is in the same direction as the thread direction of the second threaded portion, so as to reduce the situation where the connecting pipe is detached from the installation groove during the connection process of the sleeve and the connecting pipe.

[0040] To connect the connecting tube 6 to the feed pipe 2, first connect the sleeve to the second threaded portion 81 of the feed pipe 2. Then, use the rotating rod 7 to rotate the feed pipe 2 so that one side of the rotating rod 7 abuts the first positioning plate 71. At this point, the feed pipe 2 and the connecting tube 6 are facing each other. Then, rotate the sleeve toward the side of the connecting tube 6 so that the first threaded portion of the sleeve simultaneously mates with the third threaded portion 82 of the connecting tube 6, thus completing the connection between the connecting tube 6 and the feed pipe 2. This simple installation method makes it easy for workers to disassemble and assemble the feed pipe 2 and the connecting tube 6, and also facilitates cleaning of the connecting tube 6.

[0041] Reference Figure 4 In this embodiment, a rubber layer 21 is provided on the side of the connecting tube 6 close to the material tube 2. The rubber layer 21 is used to abut against the end of the material tube 2, thereby increasing the sealing effect between the connecting tube 6 and the material tube 2 and reducing the material in the material tube 2 from overflowing to the outside through the gap between the connecting tube 6 and the material tube 2.

[0042] The material pipe 2 is equipped with a feed pipe 22 and two groups of blowing pipes 23 connected thereto. The feed port of the feed pipe 22 is arranged opposite to the blowing port of one group of blowing pipes 23, and the other group of blowing pipes 23 is connected to the end of the material pipe 2 away from the connecting pipe 6; and the extension direction of the feed pipe 22 is staggered with the extension direction of the material pipe 2, so as to facilitate the passage of the material in the feed pipe 22 into the interior of the material pipe 2.

[0043] The blowing pipe 23 arranged opposite to the feed port of the feed pipe 22 can ensure that the material entering the feed pipe 22 can be evenly blown into the mold cavity 35, reducing the accumulation and blockage of the material in the material pipe 2, and ensuring the continuity and efficiency of the production process; and by installing another blowing pipe 23 at the end of the material pipe 2 away from the mold 3, it is further ensured that all the material in the material pipe 2 is pushed into the mold cavity 35, ensuring the purity of the material in the next operation.

[0044] The implementation principle of a foam board forming device in the embodiment of the present application is as follows:

[0045] After using the equipment for a long time, the connection between the material pipe 2 and the connecting pipe 6 is cancelled by rotating the sleeve. At this time, the rotating rod 7 is in contact with the second positioning plate 72 under the elastic force of the torsion spring 73. At this time, the discharge port of the material pipe 2 and the feed port of the connecting pipe 6 are staggered, so that the feed port of the connecting pipe 6 is exposed to the outside, so that the staff can clean the pipe port of the connecting pipe 6 and reduce the blockage in the connecting pipe 6, thereby increasing the speed of feeding the material pipe 2 into the mold cavity 35.

[0046] After the connecting tube 6 is cleaned, the rotating rod 7 is rotated so that the connecting tube 6 is arranged opposite the material tube 2, and the sleeve is used again to connect the material tube 2 and the connecting tube 6, so that the material in the material tube 2 can enter the mold cavity 35 through the connecting tube 6.

[0047] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
