Description

Technical Field

[0001] The present invention relates to the technical field of cement foamed board processing, and particularly relates to a multi-station production and processing equipment for cement foamed boards. Background Art

[0002] The basic principle of the cement foamed board is to utilize the incombustibility of cement and a large number of closed pores in the concrete to achieve the effects of fire prevention, light weight, and heat preservation. It is the most ideal material for wall heat preservation and wall heat preservation and fire isolation belts at present. Its main production processes are feeding, mixing, stirring, injection molding, foaming, initial curing, demolding, cutting, and packaging.

[0003] At present, the production equipment for cement foamed boards still adopts single-station operation along the production line; especially for the foaming material injection equipment, the existing injection equipment only injects foaming material into one set of molds at a time; since the curing time after the cement foamed board is injected with slurry is relatively long, while the time for injecting material into the mold is relatively short; therefore, there is a phenomenon that the foaming material injection equipment waits for the mold, resulting in mismatched production capacities among various process sections; in the existing workshops, a low production line speed production method is mostly adopted; in this way, the manufacturing cost is relatively high, the process is cumbersome, and the efficiency is low. Summary of the Invention

[0030] The preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various different forms. Therefore, the present invention is not limited to the embodiments described below. In addition, in order to describe the present invention more clearly, the components not connected to the invention will be omitted from the drawings;

[0031] The technical solution in the embodiments of this application aims to solve the problems in the above background technology, and the general idea is as follows:

[0032] As Figure 1 shown, this embodiment introduces the specific structure of a multi-station production and processing equipment for cement foamed boards, including a feeding device 1. On the left and right sides of the feeding device 1, there are a left conveyor line 2 and a right conveyor line 3 respectively; on the left conveyor line 2 and the right conveyor line 3, there are foaming molds 4; the left conveyor line 2 and the right conveyor line 3 carry the foaming molds 4 and convey them towards each other at the same speed; the left conveyor line 2 carries the empty foaming molds 4 and conveys them counterclockwise around the feeding device 1. When the empty foaming mold 4 passes by the feeding device 1, the feeding device 1 starts to inject foaming raw materials into the foaming mold 4; as the left conveyor line 2 runs, when the foaming mold 4 is filled with materials, it disengages from the feeding device 1; then pressure-holding foaming starts; after the foaming is completed, the mold is opened to obtain a cement foamed board blank; finally, the blank is cut to obtain a cement foamed board;

[0033] Similarly, the right conveyor line 3 carries the empty foaming molds 4 and conveys them clockwise around the feeding device 1. When the empty foaming mold 4 passes by the feeding device 1, the feeding device 1 starts to inject foaming raw materials into the foaming mold 4; as the right conveyor line 3 runs, when the foaming mold 4 is filled with materials, it disengages from the feeding device 1; then pressure-holding foaming starts; after the foaming is completed, the mold is opened to obtain a cement foamed board blank; finally, the blank is cut to obtain a cement foamed board; According to Figure 1 it can be known that the upper line end of the empty foaming mold 4 on the left conveyor line 2 intersects with the lower line end of the opened mold of the foaming mold 4 on the right conveyor line 3; in this way, the empty foaming mold 4 that is taken off the line when the mold is opened on the right conveyor line 3 can be transferred to the head of the left conveyor line 2 at the shortest distance; this greatly saves the material transfer time; further, the foaming mold 4 is fed by multiple stations on the left and right of the feeding device 1; this also greatly improves the production efficiency;

[0034] As Figure 7 shown, as an implementable manner, the foaming mold 4 includes a lower mold 41 and an upper mold 42; the lower mold 41 forms constraints on the bottom surface and three side surfaces of the foamed blank; the upper mold 42 forms constraints on the top surface and one side surface of the foamed blank; in this way, after the upper mold 42 is demolded, the foamed blank can still be located on the lower mold 41; during secondary demolding, only the lower mold 41 needs to be flipped 90 degrees towards the side without constraints, so that the foamed blank can just be located on the conveyor line; thus facilitating the demolding of the lower mold 41;

[0035] The top of the upper mold 42 has a suspension rod 421, and the suspension rod 421 is convenient for lifting the upper mold 42 during demolding;

[0036] The side of the upper mold 42 has a feeding port 422, which facilitates the injection of foaming material into the mold by the feeding device 1; a one-way valve is also provided inside the feeding port 422 to prevent the foaming material from overflowing when the foaming mold 4 is under pressure holding;

[0037] As Figure 2 shown, the feeding device 1 includes a base 11, a feeding head 12, a flow distribution device 13, and a indexing plate 14;

[0038] One side below the base 11 is provided with a pump feeding pipe 111, and the pump feeding pipe 111 is connected to a pump, and the stirred and mixed raw materials can be transported into the interior of the base 11 through the pump;

[0039] As Figure 3 shown, a limiting plate 112 and a limiting column 113 are respectively fixedly connected to the middle and upper parts of the base 11; the flow distribution device 13 is rotatably connected to the top of the base 11;

[0040] As Figure 5 shown, the flow distribution device 13 includes a flow distribution ring 131, and an assembly groove 1311 is opened in the middle of the bottom of the flow distribution ring 131 for sleeving on the top of the base 11; the assembly groove 1311 communicates with the pump feeding pipe 111 of the base 11;

[0041] A plurality of valve cores 1312 are arranged around the assembly groove 1311 at the bottom of the flow distribution ring 131; a plurality of connecting pipes 132 are arranged around the flow distribution ring 131; the connecting pipes 132 control the flow rate through the valve cores 1312 and communicate with the assembly groove 1311;

[0042] The number of the connecting pipes 132 corresponds to that of the valve cores 1312 one by one;

[0043] Under the rotational constraint of the limiting column 113, the valve core 1312 can control the opening and closing of the valve;

[0044] The top of the flow distribution device 13 is fixedly connected to the indexing plate 14 through a connecting rod 141; a plurality of card slots 142 are opened around the indexing plate 14; the number of the card slots 142 is the same as that of the connecting pipes 132; the card slots 142 match the suspension rods 421; when the foaming mold 4 moves on the conveying line, when the foaming mold 4 is about to approach the indexing plate 14, the suspension rod 421 of the upper mold 42 is preferentially engaged with the card slot 142, so that the movement of the foaming mold 4 can drive the indexing plate 14 to rotate; further facilitating the positioning of the feeding head 12 with respect to the feeding port 422;

[0045] As Figure 6 shown, the outer end of the connecting pipe 132 is sleeved with a feeding head 12; a limiting rod 121 is arranged below the feeding head 12, and under the rotational constraint of the limiting plate 112, the limiting rod 121 can perform telescopic movement;

[0046] As an implementable mode, a first chute 1121 is formed on the upper surface of the limit disk 112; the path of the first chute 1121 is a closed shuttle shape; the trajectories on both sides of the first chute 1121 close to the left conveyor line 2 and the right conveyor line 3 are far from the center of the base 11, and the other two sides are close to the center of the base 11; when the limit rod 121 slides on the first chute 1121 through the ball head at the lower end, since the trajectories close to the conveyor line are far from the center of the base 11, when the displacements are synthesized, the injection head 12 gradually approaches the foaming mold 4; this facilitates the insertion of the injection head 12 into the injection port 422 of each foaming mold 4 passing through the injection device 1.

[0047] As an implementable mode, a second chute 1131 is formed around the limit post 113; the valve core 1312 is slidably connected to the second chute 1131 through the slide base 1313; the path of the second chute 1131 is an unfolded wavy curve; the trajectory lines on both sides close to the left conveyor line 2 and the right conveyor line 3 are closer to the lower end of the limit post 113 (valley); the other two trajectories are close to the lower end face of the limit post 113 (peak); thus, when the valve core 1312 rotates left, right, and down on the indexing disk 14, it slides along the second chute 1131 during this process. When passing through the left conveyor line 2 and the right conveyor line 3, the valve core 1312 gradually moves downward, and the valve is in an open state during this time; thus, when each foaming mold 4 passes through the injection device 1, the valve core 1312 of the flow distribution device 13 opens, and during this time, the injection head 12 just inserts into the injection port 422 of the foaming mold 4; thereby realizing the injection of foaming material into the mold without stopping the machine. When the injection is completed, as the foaming mold 4 gradually moves away from the injection device 1; the injection head 12 gradually retracts under the action of the first chute 1121, and the valve core 1312 gradually moves upward under the action of the second chute 1131 to close the valve; finally, when the suspension rod 421 on the foaming mold 4 is completely disengaged from the card slot 142 of the indexing disk 14 and enters the foaming mold clamping and pressure maintaining state; at this time, the next empty mold on the same conveyor line will continue to engage with the card slots 142 of other workstations; subsequently, the above process will be repeated for injection; so on and so forth; realizing continuous injection of foaming material into the foaming mold 4 without stopping the machine.

[0048] Working principle:

[0049] Since the left conveyor line 2 and the right conveyor line 3 are in production simultaneously, the production process of the right conveyor line 3 is taken as an example here; First, transfer the foaming mold 4 after demolding from the left conveyor line 2 to the end of the right conveyor line 3; Place the foaming molds 4 at equal intervals on the right conveyor line 3; As the right conveyor line 3 runs, the foaming molds 4 move gradually. When the hanging rod 421 on the foaming mold 4 engages with the card slot 142 of the indexing plate 14, at this time, the foaming mold 4 will push the indexing plate 14 to move together; Since the indexing plate 14 rotates, the flow distribution device 13 below it will rotate together; When the valve core 1312 rotates left and right and down under the indexing plate 14, it slides along the second chute 1131 during this period. When the foaming mold 4 enters the injection station, the valve core 1312 gradually moves downward, and the valve is in an open state; In this way, when each foaming mold 4 passes through the injection device 1, the valve core 1312 of the flow distribution device 13 opens. During this process, the limit rod 121 slides on the first chute 1121. Since the trajectory close to the conveyor line is far from the center of the base 11, when the displacements are synthesized, the injection head 12 gradually approaches the foaming mold 4; In this way, the injection head 12 is inserted into the injection port 422 of each foaming mold 4 passing through the injection station; Thus, the foaming material can be injected into the mold continuously without stopping the machine.

[0050] After the injection is completed, as the foaming mold 4 gradually moves away from the injection device 1; The injection head 12 gradually retracts under the action of the first chute 1121, and the valve core 1312 gradually moves upward under the action of the second chute 1131 to close the valve; Finally, when the hanging rod 421 on the foaming mold 4 is completely disengaged from the card slot 142 of the indexing plate 14 and enters the foaming mold clamping and pressure maintaining state; At this time, the next empty mold on the same conveyor line will continue to engage with the card slot 142 of other workstations; Subsequently, the above process will be repeated for injection; In this cycle; The foaming mold 4 can be continuously injected with foam without stopping the machine.

[0051] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
