Description

Technical Field

[0001] The present invention relates to the technical field of foam board production, and particularly relates to a foam board production conveyor line. Background Art

[0002] Polystyrene foam board - also known as foam board, EPS board - is a white object formed by heating expandable polystyrene beads containing volatile liquid foaming agents in a mold after pre-expansion by heating. It has the structural characteristics of fine closed pores and is mainly used for building walls, roof insulation, composite board insulation, insulation of cold storages, air conditioners, vehicles, and ships, floor heating, decorative carving, etc., with very wide applications.

[0003] When the currently used polystyrene foam board is produced, it generally needs to go through processes such as sheet extrusion, foaming, extrusion and leveling, cooling, and cutting. After the foam board is extruded and leveled, it is usually sent to a conveyor line for transportation and cooled by natural cooling, or a water curtain is set between the leveling machine and the conveyor line to cool the foam board. The former has a long cooling time, while the latter cannot cool the foam board evenly, easily causing uneven stress during the forming and solidifying process of the foam board, and thus resulting in a low qualified rate of the formed foam board.

Detailed implementation manners

[0031] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0032] See Figures 1-10, a foam board production and conveying line provided by an embodiment of the present invention includes a support frame 1 and conveying rollers 11. A plurality of conveying rollers 11 are rotatably connected to the support frame 1. A water storage tank 5 is arranged at the bottom of the support frame 1, and a horizontal protection box 2 is fixedly connected to the top of the support frame 1. A steam conveying channel 3 is fixedly connected to the top of the horizontal protection box 2. The water storage tank 5 is connected to one end of a water passing tank 14 through a first conveying pipe 6. The water passing tank 14 is fixedly connected inside the support frame 1. The other end of the water passing tank 14 is connected to one end of a heat conduction copper pipe 4 through a second conveying pipe 7. The other end of the heat conduction copper pipe 4 is connected to the water inlet end of a delivery pump 10 through a third conveying pipe 8. The water outlet pipe of the delivery pump 10 is connected to a water spray head 18 through a fourth conveying pipe 9. The delivery pump 10 is fixedly connected to the front and rear sides of the horizontal protection box 2. The water spray head 18 is arranged inside the horizontal protection box 2. The heat conduction copper pipe 4 is fixedly embedded on the steam conveying channel 3. A T-shaped connecting rod 21 is fixedly connected to the inner top of the horizontal protection box 2, and a plurality of movable blades 17 are movably connected to the lower side of the T-shaped connecting rod 21. The movable blades 17 are located above the support frame 1. The water spray head 18 is arranged on the front and rear sides of the movable blades 17.

[0033] A plurality of conveying rollers 11 are provided, and the front and rear ends of the plurality of conveying pipes pass through the support frame 1 and are connected to a synchronous conveying gear 13. The synchronous conveying gear 13 is arranged inside a synchronous conveyor belt 12, and the synchronous conveying gear 13 is meshed and connected to the synchronous conveyor belt 12 through gear teeth.

[0034] During the use of the present invention, after the foam board is extruded by an extruder and leveled by a leveling machine, the foam board enters between the conveying rollers 11 and the horizontal protection box 2. The conveying rollers 11 are connected to an external driving motor, and the driving motor is operated to rotate the conveying rollers 11. The synchronous conveyor belt 12 and the synchronous conveying gear 13 are used to drive the plurality of conveying rollers 11 to rotate synchronously and convey the foam board smoothly. At the same time, a plurality of delivery pumps 10 operate to drive the cleaning water to flow. Then the cleaning water sequentially passes through the first conveying pipe 6, the second conveying pipe 7, the third conveying pipe 8, and the fourth conveying pipe 9 and enters the water spray head 18, and the water spray head 18 flushes the foam board. At the same time, a cleaning brush 15 under the foam board brushes the foam board. Then the hot steam moves from left to right in the steam conveying channel 3, heating the cleaning water, achieving the purpose of gradually cooling the foam board from left to right while conveying and cleaning the foam board, ensuring the stability of the foam board during the cooling and solidification process, with high forming stability and high qualification rate of the foam board. At the same time, blowing the foam board with steam also achieves the purpose of blowing and drying the foam board.

[0035] Such as Figures 2-4As shown in the figure, there are multiple water passing tanks 14, and the multiple water passing tanks 14 and the multiple conveying rollers 11 are arranged in an alternating manner. Both the front and rear ends of the water passing tank 14 are integrally connected with connecting pipe heads 141, and the connecting pipe heads 141 are embedded and fixed inside the support frame 1. The water storage tank 5 is connected to one end of the first conveying pipe 6, and the other end of the first conveying pipe 6 is connected to one of the connecting pipe heads 141, and the other connecting pipe head 141 is connected to one end of the second conveying pipe 7.

[0036] A plurality of cleaning brushes 15 are arranged on the upper side of the water passing tank 14. The cleaning brushes 15 are rotatably connected to the water passing tank 14 through sealed bearings. The lower ends of the cleaning brushes 15 pass through the water passing tank 14 and extend into the interior of the water passing tank 14, and are fixedly connected to the rotating impeller 16 inside the water passing tank 14. The upper surface of the cleaning brush 15 is 1 cm higher than the flat section at the highest point of the conveying roller 11.

[0037] The bristles on the cleaning brush 15 are selected from any one of nylon, PBT, PP, PET, and PVC. The bristles are selected to be soft and deformable, which is convenient for the bristles to deform and brush the lower surface of the foam board.

[0038] During the use of the present invention, the operation of the delivery pump 10 drives the cleaning water in the water storage tank 5 to start flowing. Then, the cleaning water enters the water passing tank 14 through the first conveying pipe 6. Then, the cleaning water flows in the water passing tank 14 and drives the rotating impeller 16 to rotate. The rotation of the rotating impeller 16 drives the cleaning brush 15 to rotate and cleans the bottom surface of the passing foam board. At the same time, the cleaning water leaves from the other side of the water passing tank 14 and sequentially enters the second conveying pipe 7, the heat-conducting copper pipe 4, and the third conveying pipe 8, and passes through the delivery pump 10. Then, it is sprayed out through the fourth conveying pipe 9 and the spray head 18, so as to wash the upper surface of the passing foam board. Then, the cleaning water passes through the support frame 1 and the conveying roller 11 and falls back into the water storage tank 5.

[0039] As Figures 7-9 As shown in the figure, the left side surface of the movable blade 17 is welded and fixed with ear plates 171, and the two ear plates 171 are respectively arranged on the front and rear sides of the T-shaped connecting rod 21 and are rotatably connected through a rotating shaft. The lower side surface of the movable blade 17 is adhesively fixed with a cleaning felt 19.

[0040] A V-shaped groove 172 and a diversion groove 173 are formed on the right side surface of the movable blade 17, and the V-shaped groove 172 and the diversion groove 173 are arranged in an alternating manner and are connected together. The bottom of the diversion groove 173 extends to the bottom of the movable blade 17 and is in contact with the cleaning felt 19.

[0041] During the use of the present invention, the movable blade 17 rotates around the T-shaped connecting rod 21 through a rotating shaft. When the foam board passes under the movable blade 17, the rightward movement of the foam board drives the movable blade 17 to rotate at this time. Then the movable blade 17 is arranged on the upper side of the foam board in an inclined state, and the foam board is pressed by the self-weight of the movable blade 17. Then, the rotation of the conveying roller 11 facilitates the smooth conveyance of the foam board. Then, when the water sprayed by the water spray head 18 falls on the movable blade 17, the inclined water converges along the V-shaped groove 172 at this time and is shunted through the diversion groove 173. Then, the cleaning water is evenly distributed to the bottom of the movable blade 17 and wets the cleaning felt 19. Then, the upper surface of the foam board is cleaned by the cleaning felt 19, improving the cleaning effect on the foam board.

[0042] As Figures 5-7 Shown in the figure, a steam inlet pipe 33 is fixedly connected to the left side of the steam conveying channel 3, and the steam inlet pipe 33 is communicated with an external steam generating source. A steam outlet pipe 31 is fixedly connected to the right side of the steam conveying channel 3, and the other end of the steam outlet pipe 31 is fixedly connected to a baffle and passes through the baffle and extends into the horizontal protection box 2. The baffle is fixedly connected to the right side surface of the horizontal protection box 2.

[0043] A plurality of steam outlets 32 are provided on the lower side surface of the steam conveying channel 3 and the upper side surface of the horizontal protection box 2. The steam outlets 32 on the steam conveying channel 3 correspond to the steam outlets 32 on the horizontal protection box 2 one by one and are communicated with each other. The steam outlets 32 on the steam conveying channel 3 are located at the right part of the steam conveying channel 3, and the steam outlets 32 on the horizontal protection box 2 are located at the right part of the horizontal protection box 2.

[0044] During the use of the present invention, hot steam enters the steam conveying channel 3 through the steam inlet pipe 33. Then the hot steam moves from left to right in the steam conveying channel 3 in turn. Then the hot steam comes into contact with a plurality of heat conduction copper tubes 4 respectively. Then, under the action of heat and cold exchange, the cleaning water passing through the heat conduction copper tubes 4 is heated. Then the heated cleaning water is sprayed out through the water spray head 18, thereby cleaning the foam board and gradually cooling it. At the same time, when the hot steam passes from left to right, due to the heat and cold exchange with a plurality of heat conduction copper tubes 4, the hot steam will be gradually cooled when moving from left to right. Finally, the hot steam is respectively sent into the horizontal protection box 2 through the steam outlets 32 and the steam outlet pipe 31, thereby blowing and drying the cleaned foam board. It realizes that the foam board is extruded by an extruder and leveled by a leveling machine and then sent into the horizontal protection box 2 for conveyance. It realizes that during the conveyance process, the foam board is gradually cooled, cleaned and dried, ensuring the qualified rate of the foam board during the cooling process, and also realizing the purpose of automatic cleaning and drying.

[0045] As Figure 10As shown in the figure, a plurality of sealed heat insulation plates 51 are fixedly connected inside the water storage tank 5, and the water storage tank 5 is divided into a plurality of water troughs. The plurality of first conveying pipes 6 are grouped in pairs of two, and are respectively arranged on the front side and the rear side of the water troughs, and a group of conveying pipes corresponds to one water trough. Through the sealed heat insulation plates 51, the cleaning water in the water storage tank 5 is separated, so as to ensure that the cleaning water in the water troughs at different positions has different water temperatures, and the water temperature decreases sequentially from left to right.

[0046] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
