Description

Technical Field

[0001] The utility model relates to the technical field of composite board production, in particular to a prefabricated composite board production device. Background Art

[0002] The composite slab is a better structural form combining prefabrication and cast-in-place concrete. It is a prefabricated prestressed thin plate combined with the upper cast-in-place concrete layer into a whole. Among them, the prestressed main reinforcement of the thin plate is the main reinforcement of the composite slab. The upper cast-in-place concrete layer is only equipped with negative moment reinforcement and structural reinforcement. The prestressed thin plate is used as the bottom formwork of the cast-in-place concrete layer, and it is not necessary to support the formwork for the cast-in-place layer. Therefore, the composite slab has the advantages of cast-in-place floor slab integrity, high rigidity, good crack resistance, no increase in steel consumption, and saving of formwork.

[0003] However, it should be noted that before pouring concrete, it is necessary to clean the impurities on the thin plate and sprinkle water on the upper part of the thin plate to ensure that the surface of the thin plate is fully moistened. In most cases, this step is performed by workers holding water pipes and air ducts in sequence. Not only is the labor burden heavy and the efficiency low, but the workers also follow the experience of the supervisor to water the thin plate. The amount of water is difficult to control, and it is easy to over-water in some areas, resulting in a large amount of water on the surface of the thin plate, which requires additional cleaning, adding unnecessary burden.

[0004] To this end, the utility model provides a prefabricated composite board production device to improve the efficiency and uniformity of thin board cleaning and water immersion during the composite board production process. Utility Model Content

[0016] Preferably, the connecting parts of the two air outlets of the Y-shaped tube and the transition tube are both located between two adjacent diversion tubes.

[0017] Compared with the prior art, the utility model provides a prefabricated composite board production equipment, which has the following beneficial effects:

[0018] 1. When in use, the thin plate of the laminated board is placed directly under the bellows; the blower is started to draw outside air into the bellows, and then the air is ejected from the air outlet of the bellows to blow away the dust and debris on the surface of the thin plate. At the same time, the second motor is started, and the second lead screw drives the bracket to move along the base, so that the bellows continuously blows air along the thin plate to achieve comprehensive cleaning of the surface of the thin plate;

[0019] After the bracket reaches the end of the thread of the second screw, it starts to move to the initial position. At this time, the blower is connected to the water tank, so that the water in the water tank is pumped into the bellows, and then squeezed and sprayed out from the air outlet at the bottom of the bellows, forming a high-pressure water film that is sprayed on the surface of the thin plate to water and soak the surface of the thin plate.

[0023] 5. The inner wall of the bellows is surrounded by an electric heating tube, which sprays hot air when started to dry the unexpected surface water, further preventing the retention of surface water.

[0024] Other advantages, objectives and features of the present invention will be described in the following description to some extent; and will be apparent to those skilled in the art based on the following examination and study to some extent; or, may be taught from the practice of the present invention.

DETAILED DESCRIPTION

[0031] The following will be combined with the attached embodiment of the utility model Figure 1-5 , the technical solutions in the embodiments of the utility model are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0032] Embodiment 1, in order to solve the problems existing in the prior art, this embodiment provides a prefabricated composite panel production equipment, including a base 1, a second screw 4 is rotatably installed on the base 1, a bracket 3 is threadedly installed on the second screw 4, the bracket 3 is slidably installed on the base 1 along the length direction of the base 1, a first screw 2 is rotatably installed on the bracket 3, a mounting plate 5 vertically slidably connected to the bracket 3 is threadedly installed on the first screw 2, a plurality of blowers 6 are fixed at intervals on the upper end of the mounting plate 5, the air outlets of the plurality of blowers 6 are commonly connected to a bellows 7 fixed at the bottom end of the mounting plate 5, the bellows 7 is a closed-end design, the air outlet of the bellows 7 is located at the bottom end of the bellows 7, the air inlet of the blower 6 is connected to a three-way valve 8, and the other two joints of the three-way valve 8 are respectively connected to an air inlet pipe and a water tank 11.

[0033] The three-way valve 8 includes a valve body 801, which includes three joints a, b and c. The joint a is connected to the bellows 7, the joint b is connected to the water tank 11, and the joint c is connected to the air inlet pipe. A cylindrical valve cavity is provided in the valve body 801 at the connection point of the three joints a, b and c. A valve column 802 is rotatably installed in the valve cavity. The valve column 802 is driven by a motor fixed to the outer wall of the valve body 801. A hole A is provided at the bottom end of the valve column 802, and holes B and C are provided on the side wall. Holes B and C are on the horizontal cross-section at the center of the valve column 802, and holes B and C are 90 degrees apart. Hole A corresponds to joint a and is always connected to the bellows 7.

[0034] The first lead screw 2 is driven by a first motor fixed on the bracket 3, and the second lead screw 4 is driven by a second motor fixed on the base 1; the second lead screw 4 is a reciprocating lead screw, which has a reciprocating thread, and can realize the function of unidirectional rotation and drive the axial reciprocating movement of the connecting part; the first motor and the second motor are both servo motors, and both have self-locking properties; the threads on the first lead screw 2 and the second lead screw 4 are both self-locking, so that the bracket 3 and the mounting frame can stop at any time and remain stable in a static state.

[0035] The specific use process of this embodiment is as follows:

[0036] (1) The thin plate of the laminated board is placed in the middle of the base 1 and directly below the bellows 7;

[0037] (2) Starting the first motor to drive the mounting plate 5 to move vertically so that the air outlet of the bellows 7 is close to the upper end of the sealing plate;

[0038] (3) Start the blower 6. At this time, the C hole is aligned with the c joint so that the air inlet pipe is connected to the bellows 7. The B hole is blocked by the side wall of the valve cavity. The blower 6 is started to draw the outside air into the bellows 7. Since the bellows 7 is a closed-end design, the compressed air diffuses in the bellows 7 and is ejected from the air outlet of the bellows 7 to blow away the dust and debris on the surface of the thin plate. At the same time, the second motor is started, and the second screw 4 drives the bracket 3 to move slowly along the base 1, so that the bellows 7 blows air continuously along the thin plate to achieve comprehensive cleaning of the surface of the thin plate;

[0039] (4) After the bracket 3 reaches the threaded end of the second screw 4, it starts to move toward the initial position. At this time, the motor starts and drives the valve column 802 to rotate 90° counterclockwise, so that the B hole corresponds to the b joint. At this time, the water tank 11 is connected to the bellows 7, and the C hole is blocked by the side wall of the valve cavity. At this time, the blower 6 becomes a pump body, thereby pumping the water in the water tank 11 into the bellows 7, and then the water is squeezed and sprayed out by the air outlet at the bottom of the bellows 7, forming a high-pressure water film sprayed on the surface of the thin plate, watering and soaking the surface of the thin plate. The water spraying amount of the bellows 7 remains stable, and the moving speed of the bellows 7 is stable, so that water is evenly sprayed on the surface of the thin plate to avoid excessive local water spraying and the presence of clear water (clear water is water that is obviously in the form of puddles on the surface);

[0040] (5) After the bracket 3 is reset, the blower 6 is turned off, the motor drives the valve column 802 to reset, and the first motor rotates to drive the mounting plate 5 to rise, so that the bellows 7 can move the raw material thin plate, which is convenient for the transfer of the thin plate. After the equipment as a whole returns to its initial state, the thin plate is removed and replaced with the next thin plate for cleaning.

[0041] In Example 2, the air outlet of each blower 6 is connected to a Y-shaped tube, and multiple Y-shaped tubes are commonly connected to a transition tube. The bottom end of the transition tube is connected to multiple branch tubes, and the branch tubes are evenly spaced along the length direction of the bellows 7. The connecting parts between the two air outlets of the Y-shaped tube and the transition tube are located between two adjacent branch tubes, so that the compressed wind blown by the blower 6 can enter the bellows 7 more evenly and diffuse more evenly in the bellows 7, so that the wind pressure of the wind ejected from the wind box 7 is kept similar, and the problem of low local wind pressure and inability to completely treat the dust will not occur.

[0042] In Embodiment 3, dust and impurities blown away by the blower 6 will make the air in the workshop working environment polluted, which will not only affect the workers' vision, but also affect the workers' health after being inhaled. Therefore, in order to suppress the random dissipation of dust blown away from the surface of the thin plate as much as possible, in this embodiment, a bracket is fixed on the side of the bellows 7 facing the direction of travel, and a dust collector 13 is provided on the bracket. The dust collector 13 includes a dust box 1301 detachably mounted on the bracket, and a suction pump is detachably connected to the bottom end of the dust box 1301. A dust hood 1302 is connected to the bottom end of the suction pump. The dust hood 1302 is flared and tilted along the horizontal direction of the bellows 7. The dust blown away by the bellows 7 is sucked into the dust box 1301 from the dust hood 1302 through the suction pump, thereby reducing the dissipation of dust.

[0043] Preferably, a filter box 9 is embedded at the mouth of the air inlet pipe to filter the air entering the blower 6 from the outside, reduce the dust content of the air sprayed by the blower 6, and then reduce the amount of dust escape, and can also share the pressure of the suction pump to a certain extent.

[0044] Preferably, an air guide plate 14 is fixed at the air outlet at the bottom end of the bellows 7, so that the wind sprayed from the bellows 7 is inclined toward the dust collecting hood 1302, and then the dust blown off the surface of the thin plate is dispersed toward the dust collecting hood 1302, thereby improving the collection effect of the dust collecting hood 1302, and then improving the dust collection effect.

[0045] Embodiment 4, since the bracket 3 will move, and the water tank 11 is relatively fixed, in this embodiment, a hose 10 is connected to the side wall of the bottom end of the water tank 11, and the hose 10 is connected to the b joint of the three-way valve 8. The hose 10 can be bent, so that the bracket 3 can always ensure a stable water supply to the water tank 11 during the movement.

[0046] Preferably, a drag chain 12 is arranged on the base 1, and the hose 10 is divided into three parts in sequence, one part shuttles through the drag chain 12, one part is attached to the side of the bracket 3 with a structure such as a strap, and one part is suspended at the upper end of the bracket 3 as the vertical lifting margin of the mounting plate 5. The drag chain 12 restricts this part of the hose 10 during the reciprocating movement of the bracket 3, and can bend with the drag chain 12 without closing the folded part, thereby ensuring the permeability of the hose 10.

[0047] Embodiment 5, the inner wall of the bellows 7 is surrounded by an electric heating tube, and at this time, the bracket 3 reciprocates along the second lead screw 4 for two round trips as one cycle:

[0048] The first time, the water tank 11 is moved to spray air;

[0049] The first return to the water tank 11 sprays water;

[0050] During the second round trip, the electric heating tube starts to spray hot air to dry the unexpectedly existing clear water, further preventing the retention of clear water.

[0051] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
