Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing devices, in particular to a hot pressing device for a hemp fiberboard. Background Art

[0002] Hemp fiberboard is a board material made of hemp stalk fiber. It is lightweight and environmentally friendly, so it is widely used in construction, furniture manufacturing and other fields. During the processing of hemp fiberboard, it is first pre-pressed and then further pressed by a hot pressing device, which can reduce the thickness of the fiberboard and increase its compactness and hardness.

[0003] Traditional hot pressing devices are usually equipped with conveying components to perform hot pressing while conveying longer hemp fiber boards. However, the traditional conveying component drive device and the hot pressing component drive device are often two independent units, which work independently and do not interfere with each other. Although this design simplifies the structure of the equipment to a certain extent, it brings operational inconvenience. In the actual production process, the conveying component may still work during hot pressing. In this case, the hemp fiber board is not only subjected to hot pressing, but also to the thrust of the conveying component, which can easily cause the board to bend, deform and other problems. This not only affects the quality of the hemp fiber board, but may also lead to increased production costs and waste of resources. Therefore, it is necessary to develop a hemp fiber board hot pressing device. Utility Model Content

[0028] See also Figure 1-Figure 5 , shows a schematic diagram of the structure of a hemp fiberboard hot pressing device of the utility model, please refer to Figure 1-Figure 5 , a hemp fiberboard hot pressing device is introduced in detail.

[0029] A hemp fiberboard hot pressing device comprises a mounting plate 100, a lifting plate 110 is lifted and arranged between two mounting plates 100, an upper electric heating plate 120 is arranged below the lifting plate 110, a lower electric heating plate 130 is arranged at the top of the lower mounting plate 100 directly below the upper electric heating plate 120, a lifting block 140 is arranged on the front side wall of the lifting plate 110, mounting blocks 150 are arranged on the upper and lower sides of the lifting block 140 on the front side walls of the two mounting plates 100, a vertical reciprocating screw rod 160 is rotatably arranged between the two mounting blocks 150, and the rod body of the reciprocating screw rod 160 is transmitted through the upper and lower walls of the lifting block 140;

[0030] The right side of the mounting plate 100 is symmetrically provided with mounting frames 200, and a longitudinal row of rotating rods 210 are rotatably provided at equal intervals at the lower part between the two mounting frames 200, and a conveying cylinder 220 is sleeved on the outer side of the rod body of each rotating rod 210, and all the rotating rods 210 and the reciprocating screw rod 160 are driven simultaneously by the driving assembly;

[0031] The driving assembly includes a fixing frame 300, which is arranged in front of the mounting plate 100 and the mounting frame 200. A horizontal driving rod 310 is rotatably provided through the side wall of the fixing frame 300. A worm gear 330 is provided at the front end of each rotating rod 210. A worm 320 meshing with each worm gear 330 is provided on the rod body of the driving rod 310. A follower bevel gear 340 is provided at the lower end of the reciprocating screw rod 160. An active bevel gear 350 meshing with the follower bevel gear 340 is provided at the left end of the driving rod 310. The left side of the active bevel gear 350 is connected to the output end of the servo motor 360.

[0032] Furthermore, vertical guide support rods 170 are arranged between the two mounting plates 100. There are four guide support rods 170 in total and they are respectively located near the top corners of the mounting plates 100. The rod bodies of the four guide support rods 170 respectively slide through the positions of the lifting plates 110 at the top corners, and linear bearings are arranged on the inner sides of the penetration positions of the lifting plates 110. The inner sides of the linear bearings are slidably connected with the rod bodies of the guide support rods 170. The guide support rods 170 are staggered with the upper heating plate 120 and the lower heating plate 130. When the lifting plate 110 is lifted or lowered, the guide support rods 170 play a role of limiting and guiding the lifting plate 110, and the linear bearings arranged will also reduce the friction between the lifting plate 110 and the guide support rods 170.

[0033] Furthermore, a vertical row of slide bars 230 are slidably arranged at equal intervals on the top of the two mounting frames 200, a fixed rod 240 is fixedly arranged between the lower ends of the front and rear slide bars 230, a cylindrical rotating drum 250 is arranged on the outer side of the rod body of the fixed rod 240 for rotation, the rotating drum 250 is located directly above the conveying drum 220, and the position and number of the rotating drum 250 correspond to the position and number of the conveying drum 220, and the outer side of the rod body of each slide bar 230 is sleeved on the inner side of the vertical spring 260 The upper and lower ends of the spring 260 are respectively fixed to the top wall of the mounting frame 200 and the top of the fixing rod 240. A pull plate 270 is provided at the top of each sliding rod 230. A handle 280 is provided at the top of the pull plate 270. The spring 260 will push the fixing rod 240 to properly press down the hemp fiberboard, thereby playing a proper flattening function, which is beneficial to the later hot pressing process of the hemp fiberboard. Since the fixing rod 240 is rotatably connected to the rotating drum 250, it will not hinder the transportation of the hemp fiberboard.

[0034] Furthermore, a shell 370 is provided in front of the mounting plate 100 and the mounting frame 200. The shafts of the reciprocating screw 160 and the rotating rod 210 both pass through the side wall of the shell 370. The inner cavity of the shell 370 accommodates the driving component to prevent the driving component from being exposed to the outside.

[0035] Furthermore, a mounting frame 400 is provided on the left side of the mounting plate 100, and an inlet and outlet 410 are opened on the left and right side walls of the mounting frame 400, and heat dissipation nets 430 are provided on the upper and lower front and rear side walls of the inlet and outlet 410, and a plurality of cooling fans 420 are provided on the bottom of the lower heat dissipation net 430 and the top of the upper heat dissipation net 430. After hot pressing, the hemp fiberboard enters the interior of the mounting frame 400 through the inlet and outlet 410, and the cooling fan 420 is started to cool it down for easy shaping.

[0036] In the specific use process, firstly, the handle 280 is used to pull the pull plate 270 to drive all the slide bars 230 to rise, so that the rotating drum 250 and the conveying drum 220 are separated, and then the hemp fiber board to be heat-treated is placed between the conveying drum 220 and the rotating drum 250. After the handle 280 is released, the spring 260 will push the fixing rod 240 to appropriately press down the hemp fiber board to play a proper flattening function, and then the servo motor 360 is started to drive the driving rod 310 to rotate, and the worm 320 and the worm gear 330 are used to make all the rotating rods 210 rotate, so that the hemp fiber board is gradually sent between the lower electric heating plate 130 and the upper electric heating plate 120. At the same time, the driving rod 310 is driven by the active bevel gear The wheel 350 and the follower bevel gear 340 drive the reciprocating screw rod 160 to rotate, so that the lifting plate 110 gradually descends. When the lifting plate 110 presses the hemp fiber board between the upper electric heating plate 120 and the lower electric heating plate 130, the servo motor 360 is stopped, and at the same time, the conveying cylinder 220 also stops rotating and conveying, and then the upper electric heating plate 120 and the lower electric heating plate 130 are started to hot-press the hemp fiber board to avoid the conveying components still working during hot pressing, which causes the hemp fiber board to bend. After the hot pressing is completed, the servo motor 360 is started again, the lifting plate 110 gradually rises, and the conveying cylinder 220 then delivers the hot-pressed hemp fiber board into the inlet and outlet 410, and drives the cooling fan 420 to cool it.

[0037] It should be noted that the length of the hemp fiber board hot-pressed by the upper electric heating plate 120 and the lower electric heating plate 130 each time is a unit length of the hemp fiber board, and when the unit length of the hemp fiber board is conveyed by the conveying cylinder 220, the left edge of the unit length of the hemp fiber board moves from the rightmost end position of the lower electric heating plate 130 to the leftmost end of the lower electric heating plate 130, which is recorded as a unit stroke, and the unit stroke is the stroke of the lifting block 140 reciprocating along the reciprocating screw rod 160 once, and the left end of the hemp fiber board The edge is initially placed at the left edge of the lower electric heating plate 130, and the initialization position of the lifting plate 110 is that the lifting block 140 is located at the bottom of the transmission position of the reciprocating screw rod 160. When the unit length of the hemp fiberboard is transported by a unit stroke, the lifting block 140 moves from the lowest point to the highest point, and then moves from the highest point to the lowest point, thereby restarting the upper electric heating plate 120 and the lower electric heating plate 130 to heat-press the hemp fiberboard, thereby reducing the area where the hemp fiberboard is not hot-pressed and is directly transported.

[0038] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
