Description

Technical Field

[0001] This application relates to the field of foamed cotton production machinery, and particularly to an exhaust device for a foaming machine. Background Art

[0002] Foamed cotton is a material with small density containing air holes, having better heat insulation and sound insulation and shock absorption properties, and is widely used in the field of civilian products. Foamed cotton is produced by a foaming machine. During the production of foamed cotton, by injecting the foamed cotton material into a mold, the foamed cotton can be shaped in the cavity of the mold, and then foamed cotton of different shapes can be made.

[0003] Related foamed cotton molds include an upper template and a lower template. Cavities are provided on both the upper template and the lower template. The upper template and the lower template are abutted against each other to form a space of a specific shape surrounded by the cavities. Feed holes and air holes are provided on the templates. Both the feed holes and the air holes are communicated with the cavities of the templates. The foaming machine can fill the foamed cotton material into the cavities through the feed holes, and the air in the cavities is discharged through the air holes. The foamed cotton material can expand and fill the cavities, and finally form a foamed cotton product with the same shape as the cavities.

[0004] The above-mentioned related technical solutions have the following defects: During the production of foamed cotton, the foamed cotton is prone to expand and block the air holes, thereby preventing the air in the cavities from being discharged, causing the foamed cotton to not fully fill the cavities after expansion, resulting in the shape of the foamed cotton product not meeting the predetermined requirements and poor production quality. Content of the Utility Model

[0005] In order to improve the production quality of foamed cotton products, this application provides an exhaust device for a foaming machine.

[0006] An exhaust device for a foaming machine provided by this application adopts the following technical solution:

[0007] An exhaust device for a foaming machine includes a frame, an upper template and a lower template. The frame includes a base frame, a cover plate and shaft seats. The shaft seats are respectively fixed on the base frame and the cover plate. The base frame and the cover plate are rotatably connected. The upper template is installed on the cover plate, and the lower template is installed on the base frame. A cavity one is provided on the upper template, an air hole two is provided on the upper template, an air hole one is provided on the cover plate, and the air hole one and the air hole two are communicated. A cavity two is provided on the lower template, and a feed hole is provided on the lower template. The feed hole is communicated with the cavity two. A pressure sensor is arranged inside the upper template.

[0008] By adopting the above technical solution, a lower template is arranged on the chassis, and an upper template is arranged on the cover plate. The user rotates the cover plate, so that the upper template can rotate with the cover plate and press on the lower template, and then the foam material can be formed in the cavity. By arranging a pressure sensor in cavity one, the pressure sensor can detect the air pressure in cavity one. When the foam material blocks air hole one and air hole two, the air in the cavity cannot be discharged, so that the pressure in the cavity increases. The pressure sensor can send an electrical signal. The user inserts a tool into the air hole and extrudes the foam according to the reading of the pressure sensor, so that the air in the cavity can be discharged from the air hole, improving the production quality of the foam product.

[0009] Optionally, a clamping strip is arranged on the chassis, and the clamping strip is used for clamping on the outer side wall of the lower template.

[0010] By adopting the above technical solution, by arranging a clamping strip on the chassis, the clamping strip forms a semi-surrounding frame body, and the lower template is arranged in the semi-surrounding frame body. The clamping strip plays a positioning role, enabling the lower template to maintain a stable position on the chassis and keeping the positions of cavity one and cavity two stable, improving the production quality of the foam.

[0011] Optionally, a plurality of upper locking parts are installed on the cover plate, and a plurality of lower locking parts are arranged on the chassis. The upper locking parts and the lower locking parts are detachably connected.

[0012] By adopting the above technical solution, by arranging upper locking parts on the cover plate and lower locking parts on the chassis, the upper locking parts and the lower locking parts can be detachably connected. When the upper template and the lower template are mutually attached, the user connects the upper locking parts and the lower locking parts to each other, which can make the upper template and the lower template closely attached, thereby reducing the probability of the foam material oozing out between the upper template and the lower template.

[0013] Optionally, an exhaust mechanism is arranged on the upper template. The exhaust mechanism includes an exhaust pipe and a pressing plate. The pressing plate is arranged in cavity one. The exhaust pipe includes a horizontal part and a vertical part. The horizontal part is arranged at one end of the cover plate far from the upper template, and the vertical part is inserted into air hole one and air hole two and connected to the pressing plate. A through hole is formed on the pressing plate, and the through hole is communicated with the exhaust pipe. The vertical part is used for sliding and rotating in air hole one.

[0014] By adopting the above technical solution, by arranging an exhaust pipe on the cover plate and connecting the end of the exhaust pipe to the pressing plate, the user can press the pressing plate through the horizontal part, so that the pressing plate can press the foam material in the cavity, and then the air in the cavity is discharged. The user can rotate the horizontal part to make the pressing plate rotate in the cavity, so that the pressing plate can extrude different positions of the foam, completely exhausting the air in the cavity and further improving the production quality of the foam.

[0015] Optionally, a receiving groove is formed on the inner bottom surface of the first cavity. The shape of the receiving groove is the same as that of the pressing plate. When the pressing plate is arranged in the receiving groove, the surface of the pressing plate is flush with the inner bottom surface of the first cavity.

[0016] By adopting the above technical solution, a receiving groove is formed in the first cavity, so that the pressing plate can slide into the receiving groove, and then the inner bottom surface of the first cavity is kept flat. When the foamed cotton material is shaped in the cavity, the upper surface of the foamed cotton can be kept flat, improving the production quality.

[0017] Optionally, a plurality of side air holes are formed in the vertical portion. The side air holes penetrate through the exhaust pipe, and the side air holes are located on one side of the vertical portion close to the pressing plate.

[0018] By adopting the above technical solution, by forming side air holes in the vertical portion, the side air holes on the vertical portion are located in the second air hole. When the user presses the pressing plate on the foamed cotton material, the foamed cotton material blocks the through holes on the pressing plate, and it is difficult for the air in the cavity to be discharged through the exhaust pipe. By forming side air holes, the air in the cavity can enter the exhaust pipe through the side air holes, which is convenient for use.

[0019] Optionally, a convex circle is arranged on the vertical portion, and a return spring is sleeved on the vertical portion. One end of the return spring abuts against the convex circle, and the other end abuts against the cover plate.

[0020] By adopting the above technical solution, by arranging a convex circle on the vertical portion, one end of the return spring abuts against the convex circle, and the other end abuts against the cover plate. The return spring can support the exhaust pipe and the pressing plate, so that the pressing plate always abuts against the inner bottom surface of the first cavity.

[0021] Optionally, an indicating needle is arranged on the convex circle. The length direction of the indicating needle coincides with the length direction of the pressing plate, and an indicating groove is formed on the cover plate. The length direction of the indicating groove coincides with the length direction of the receiving groove.

[0022] By adopting the above technical solution, by arranging an indicating needle on the convex circle, the user can rotate the horizontal portion according to the positions of the indicating needle and the indicating groove, so that the pressing plate can be received in the receiving groove, which is convenient for use.

[0023] In summary, the beneficial technical effects of the present application are as follows:

[0024] 1. By setting a lower template on the chassis and an upper template on the cover plate, the user can rotate the cover plate, enabling the upper template to rotate with the cover plate and press on the lower template. As a result, the foam material can be formed in the cavity. By installing a pressure sensor in cavity one, the pressure sensor can detect the air pressure in cavity one. When the foam material blocks air holes one and two, the air in the cavity cannot escape, causing the pressure in the cavity to rise. The pressure sensor can send an electrical signal, and the user can insert a tool into the air hole and squeeze the foam according to the reading of the pressure sensor, allowing the air in the cavity to escape from the air hole and improving the production quality of the foam product.

[0025] 2. By setting an upper locking part on the cover plate and a lower locking part on the chassis, the upper and lower locking parts can be detachably connected. When the upper and lower templates are in contact with each other, the user can connect the upper and lower locking parts, enabling the upper and lower templates to fit tightly, thereby reducing the probability of the foam material leaking out between the upper and lower templates.

[0026] 3. By setting an exhaust pipe on the cover plate and connecting the end of the exhaust pipe to the pressure plate, the user can press the pressure plate through the horizontal part, causing the pressure plate to press the foam material in the cavity, thereby discharging the air in the cavity. By rotating the horizontal part, the user can make the pressure plate rotate in the cavity, enabling the pressure plate to squeeze different positions of the foam and completely evacuating the air in the cavity, further improving the production quality of the foam.

Detailed implementation manners

[0033] The following further elaborates on the present application in conjunction with the accompanying drawings.

[0034] The embodiment of the present application discloses an exhaust device for a foaming machine. Refer to Figure 1 and Figure 2 , which includes a frame 1, an upper template 2 and a lower template 3. The frame 1 includes a chassis 11, a cover plate 12 and a plurality of shaft seats 13. The chassis 11 is horizontally arranged, and the shaft seats 13 are respectively fixed on the chassis 11 and the cover plate 12. The chassis 11 and the cover plate 12 are rotationally connected through the shaft seats 13. The lower template 3 is detachably connected to the chassis 11, and the upper template 2 is detachably connected to the cover plate 12. The cover plate 12 is used to drive the upper template 2 to rotate so that the upper template 2 can cover the lower template 3. A cavity I 21 is formed on the upper template 2, and a cavity II 31 is formed on the lower template 3. When the upper template 2 abuts against the lower template 3, the cavity I 21 and the cavity II 31 form a closed space. A feed hole 32 is formed on the lower template 3, and the feed hole 32 communicates with the cavity II 31. The foaming machine can fill the foaming cotton material into the cavity II 31 through the feed hole 32, so that the foaming cotton can be shaped in the cavity I 21 and the cavity II 31.

[0035] Refer to Figure 2 , Figure 3 and Figure 4 , an air hole II 22 is formed on the upper template 2, and the air hole II 22 communicates with the cavity I 21. An air hole I 122 is formed on the cover plate 12. When the upper template 2 is fixed on the cover plate 12, the air hole I 122 communicates with the air hole II 22. During the production of the foaming cotton, the air in the cavity I 21 and the cavity II 31 is discharged through the air hole I 122 and the air hole II 22, so that the foaming cotton can completely fill the cavity I 21 and the cavity II 31, and the shape of the foaming cotton after forming meets the requirements.

[0036] Refer to Figure 1 and Figure 2, a pressure sensor is provided on the upper template 2. The pressure sensor is installed in the cavity one 21. A wire is connected to the pressure sensor, and the wire extends outside the upper template 2 through the air hole one 122 and the air hole two 22. The pressure sensor can be an air pressure sensor. By monitoring the pressure in the cavity one 21, it can be judged whether the air in the cavity one 21 is completely emptied. When there is air in the cavity one 21 and the foam cotton blocks the air hole two 22, the air cannot be discharged from the cavity one 21. At this time, the reading of the pressure sensor is relatively large. The user can insert a tool into the air hole one 122 and the air hole two 22 and squeeze the foam cotton according to the reading of the pressure sensor, so that the air in the cavity one 21 can be discharged through the air hole two 22.

[0037] Refer to Figure 1 , a clamping strip 111 is provided on the chassis 11. The clamping strip 111 is set as a semi-surrounding frame structure. When the lower template 3 is set on the chassis 11, the clamping strip 111 is clamped on the side wall of the lower template 3 and plays a role in fixing the lower template 3, enabling the upper template 2 and the lower template 3 to fit together. A plurality of relief grooves 112 are formed on the clamping strip 111. The relief grooves 112 are formed on the side of the clamping strip 111 that abuts against the lower template 3. A plurality of handles 33 are provided on the lower template 3. The handles 33 are fixed on the outer side wall of the lower template 3. The user can lift and move the lower template 3 through the handles 33. After the user lifts the lower template 3, a tool such as a crowbar can be inserted through the relief grooves 112 to pry up the lower template 3, which is convenient for the user to set lower templates 3 of different shapes on the chassis 11.

[0038] Refer to Figure 1 and Figure 2 , a plurality of lower locking parts 113 are provided on the chassis 11, and a plurality of upper locking parts 121 are provided on the cover plate 12. The positions of the lower locking parts 113 and the upper locking parts 121 correspond one by one. When the cover plate 12 is covered on the chassis 11, the upper locking part 121 is connected to the lower locking part 113, so that the upper template 2 and the lower template 3 are closely attached, reducing the chance of the foam cotton material overflowing from the gap between the upper template 2 and the lower template 3.

[0039] Refer to Figure 1, an exhaust mechanism 4 is provided on the cover plate 12. The exhaust mechanism 4 includes an exhaust pipe 41 and a pressing plate 42. The exhaust pipe 41 includes a horizontal portion 411 and a vertical portion 412, and the horizontal portion 411 and the vertical portion 412 are connected and perpendicular. The vertical portion 412 is inserted into the first air hole 122 and the second air hole 22, and the horizontal portion 411 is located on the side of the cover plate 12 away from the upper template 2. The pressing plate 42 is arranged in the first cavity 21 and fixedly connected to the lower end of the vertical portion 412. The pressing plate 42 is of a flat plate structure and parallel to the bottom surface of the first cavity 21. By rotating the horizontal portion 411, the user can rotate the pressing plate 42 in the first cavity 21. By pressing the horizontal portion 411, the user can make the vertical portion 412 slide on the cover plate 12 along the length direction of the vertical portion 412, so that the pressing plate 42 can extrude the foam in the first cavity 21.

[0040] Refer to Figure 3 , through holes are formed in the pressing plate 42, and the through holes are communicated with the channels of the exhaust pipe 41. In the natural state, air can be discharged through the exhaust pipe 41 during the process of the foam filling the first cavity 21.

[0041] Refer to Figure 3 and Figure 4 , a plurality of side air holes 415 are formed in the vertical portion 412. The opening direction of the side air holes 415 is perpendicular to the length direction of the vertical portion 412. The side air holes 415 are located on the side of the vertical portion 412 close to the pressing plate 42, and the side air holes 415 are communicated with the internal channels of the exhaust pipe 41. When the pressing plate 42 is in contact with the inner wall of the first cavity 21, the side air holes 415 are located in the second air hole 22, so that the air in the first cavity 21 can be discharged through the through holes on the pressing plate 42. When the user presses the exhaust pipe 41, the pressing plate 42 abuts against the foam. At this time, the foam blocks the through holes on the pressing plate 42, and the air in the first cavity 21 can be discharged through the side air holes 415.

[0042] Refer to Figure 5 , a convex circle 413 is fixed on the vertical portion 412. The convex circle 413 is located on the side of the cover plate 12 away from the upper template 2. A return spring 43 is sleeved on the vertical portion 412. One end of the return spring 43 is fixed on the convex circle 413, and the other end abuts against the cover plate 12. In the natural state, the return spring 43 supports the convex circle 413, so that the pressing plate 42 is kept in contact with the bottom of the first cavity 21. When the user presses the exhaust pipe 41, the return spring 43 contracts. After the user completes the exhaust work in the cavity, the return spring 43 can drive the pressing plate 42 to move upward automatically.

[0043] Refer to Figure 4, a receiving groove 23 is formed on the inner bottom surface of the first cavity 21, and the shape of the receiving groove 23 is the same as that of the pressing plate 42. When the pressing plate 42 is attached to the inner bottom of the first cavity 21, the pressing plate 42 can be received into the receiving groove 23, so that the surface of the pressing plate 42 is flush with the inner bottom of the first cavity 21, thereby making the upper surface of the foam cotton flat after shaping.

[0044] Referring to Figure 5 , an indicating needle 414 is provided on the convex circle 413, and the length direction of the indicating needle 414 coincides with the length direction of the pressing plate 42. An indicating groove is formed on the surface of the cover plate 12, and the length direction of the indicating groove coincides with the length direction of the receiving groove 23. The user can rotate the exhaust pipe 41 according to the indicating needle 414, so that the pressing plate 42 can be rotated to a state where it fits with the position of the receiving groove 23, and at this time the pressing plate 42 can be received into the receiving groove 23.

[0045] The implementation principle of the embodiment of the present application is as follows: By providing the lower template 3 on the chassis 11 and the upper template 2 on the cover plate 12, the upper template 2 can be rotated through the cover plate 12 and attached to the lower template 3, so that the foam cotton can be shaped in the space formed by the first cavity 21 and the second cavity 31. By providing the first air holes 122 on the cover plate 12 and the second air holes 22 on the upper template 2, the air in the cavity can be discharged through the air holes. The user can use tools to squeeze the foam cotton according to the data of the pressure sensor, so that the air holes remain unblocked and the air in the cavity can be discharged.

[0046] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
