Description

Technical Field

[0001] This utility model relates to the field of aerated concrete technology, and in particular to an aerated concrete wire cutting machine. Background Technology

[0002] During the production of aerated concrete panels, cutting equipment is needed to divide the panels for easier use later.

[0003] Chinese utility model patent application No. 201820130599.4 discloses an aerated concrete wire cutting machine, which solves the problem that after the wire cutting machine is used, it is necessary to disassemble and clean the wire. Because the two ends of the wire are wrapped around swing seats one and two respectively, the wire cleaning process is complicated. The key points of the technical solution are: it includes two symmetrically arranged swing seats, a cutting wire fixedly connected to the swing seats, and a swing mechanism for driving the swing seats to swing. It also includes a cleaning box fixedly connected to the swing seats, a wire reel rotatably connected to the swing seats, and a rotating handle fixedly connected to the wire reel. The cleaning box has a through cleaning chamber, and a cleaning brush is provided in the cleaning chamber. The two ends of the cutting wire pass through the cleaning chamber and are wrapped and fixed to the wire reel. The cleaning chamber is connected to a water inlet pipe, which has the effect of quickly cleaning the wire.

[0004] However, when the equipment is in use, the residual water stains on the cleaned steel wire will generate mud on the aerated concrete blank after it is unwound and cut. This results in a lot of mud accumulating at the cut edges, and the mud solidifies, making it more difficult to break the board later. Utility Model Content

[0005] To address the above problems, this utility model provides an aerated concrete wire cutting machine. It uses two sets of winding and unwinding assemblies to wind and unwind the wire, and the drive unit drives the sliding sleeve to move. During winding, the hollow main shaft rotates and the water spray nozzle sprays water to clean the wire. During unwinding, the air spray nozzle dries the wire, thus keeping the wire dry and the aerated concrete blank at all times. This effectively prevents the generation of mud at the cutting edge and solves the cutting problem caused by water stains on the wire in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An aerated concrete wire cutting machine, comprising:

[0008] The frame is configured as a frame structure, with the aerated concrete billet passing through the middle;

[0009] A cutting mechanism, comprising several sets of cutting mechanisms distributed along the length of the frame and staggered at height, the cutting mechanism including two sets of cutting units symmetrically arranged on the frame and steel wire arranged between the two sets of cutting units and capable of being wound and unwound;

[0010] The cutting unit includes a cleaning assembly and a winding assembly mounted on the frame. The cleaning assembly includes a hollow main shaft that is rotatably mounted and can accommodate the passage of the steel wire, several sets of water spray nozzles and several sets of air spray nozzles that are arrayed along the length of the hollow main shaft and distributed circumferentially on the inner wall of the hollow main shaft, a sliding sleeve that is slidably mounted on the outside of the hollow main shaft and connected to an external water and air supply device, and a drive pair that drives the sliding sleeve to move. The movement of the sliding sleeve controls the alternating conduction of the water spray nozzles and air spray nozzles.

[0011] As an improvement, the cleaning assembly further includes bearing mounting seats installed on the front and rear sides of the frame column, a bearing correspondingly disposed on the bearing mounting seats for mounting the hollow spindle, a bearing pressure plate installed on the bearing mounting seats for pressing the outer ring of the bearing, a locking nut threadedly disposed on the rear side of the hollow spindle and abutting against the inner ring of the bearing on the rear side, a pressure ring disposed on the hollow spindle and abutting against the inner ring of the bearing on the front side, and a power pair for driving the hollow spindle to rotate.

[0012] As an improvement, the power pair includes a gear a coaxially connected to the hollow main shaft, a motor mounting plate a disposed on the frame column, a motor a disposed on the motor mounting plate a, and a gear b disposed on the motor a and meshing with the gear a.

[0013] As an improvement, the hollow spindle includes a spindle body, several sets of permeable holes a opened on the spindle body, two sets of blocks set at both ends of the spindle body, and through holes a and through holes b respectively opened on the corresponding blocks and coaxial with the spindle body. The through holes a are arranged facing the aerated concrete passage path, and the through holes b are arranged facing the winding and unwinding assembly.

[0014] As an improvement, the stop is arranged in a conical funnel shape facing the inner side of the main shaft body.

[0015] As an improvement, the through hole b is clearance-fitted with the steel wire, and the diameter of the through hole b is larger than the diameter of the through hole a.

[0016] As an improvement, the sliding sleeve includes a sliding sleeve body, a rotary joint rotatably mounted at both ends of the sliding sleeve body and respectively connected to an external water supply and air supply device, a water-permeable hole b opened on the sliding sleeve body, and a pipe disposed in the sliding sleeve body and connecting the water spray port and the air spray port and the corresponding rotary joint.

[0017] As an improvement, the extension direction of the water nozzle and air nozzle is consistent with the movement direction of the steel wire.

[0018] As an improvement, the drive pair includes a fixing bar circumferentially disposed on the sliding sleeve body, a mounting plate disposed on the side of the frame column, a slider rail pair disposed on the mounting plate, a shift fork disposed on the slider rail pair and locked on the fixing bar, a cylinder mounting seat disposed on the mounting plate, and a cylinder disposed on the cylinder mounting seat and whose power output end is connected to the shift fork.

[0019] As an improvement, the take-up and unwinding assembly includes a mounting platform installed on the outside of the frame column, a wheel that is rotatably mounted on the mounting platform via a bracket and can wind the steel wire, a motor mounting plate b disposed on the mounting platform, a motor b disposed on the motor mounting plate b, and a gear transmission unit that powerly connects the power output shaft of the motor b and the wheel.

[0020] The beneficial effects of this utility model are as follows:

[0021] (1) In this utility model, when the winding and unwinding assembly is winding, the drive pair drives the sliding sleeve to move so that the water nozzle sprays water onto the steel wire, and the hollow main shaft rotates to clean the steel wire. The water flow washes away the mud and dirt attached to the steel wire, thus cleaning the steel wire.

[0022] (2) When the winding and unwinding assembly of this utility model is unwinding, the drive pair drives the sliding sleeve to move so that the air jet nozzle sprays water onto the steel wire, and the hollow main shaft rotates to clean the steel wire. The airflow dries the water stains attached to the steel wire, thus achieving the drying of the steel wire and ensuring that the steel wire remains dry during cutting, preventing mud from being generated at the cutting edge of the aerated concrete.

[0023] (3) In this utility model, when the steel wire cuts the aerated concrete billet, the winding and unwinding components on both sides adopt a winding and unwinding form, which makes the cutting of the aerated concrete billet by the steel wire more efficient and faster.

[0024] In summary, this utility model has the advantages of simple structure, high cutting efficiency and good cutting effect, and is especially suitable for the field of aerated concrete production technology. Attached Figure Description

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Example:

[0036] like Figures 1 to 3 As shown, an aerated concrete wire cutting machine includes:

[0037] Frame 1, wherein the frame 1 is configured as a frame structure, and the middle is the passageway for the aerated concrete billet;

[0038] Cutting mechanism 2, several sets of cutting mechanisms 2 are distributed along the length direction of the frame 1 and are staggered in height. The cutting mechanism 2 includes two sets of cutting units 21 symmetrically arranged on the frame 1 and steel wire 22 arranged between the two sets of cutting units 21 and capable of being wound and unwound.

[0039] The cutting unit 21 includes a cleaning assembly 211 and a winding and unwinding assembly 212 mounted on the frame 1. The cleaning assembly 211 includes a hollow main shaft 2111 that is rotatably mounted and can accommodate the passage of the steel wire 22, a number of water spray nozzles 2112 and a number of air spray nozzles 2113 that are arrayed along the length of the hollow main shaft 2111 and are respectively circumferentially distributed on the inner wall of the hollow main shaft 2111, a sliding sleeve 2114 that is slidably mounted on the outside of the hollow main shaft 2111 and connected to an external water and air supply device, and a drive pair 2115 that drives the sliding sleeve 2114 to move. The movement of the sliding sleeve 2114 controls the alternating conduction of the water spray nozzles 2112 and the air spray nozzles 2113.

[0040] It should be noted that the frame 1 is a frame structure welded from square tubes. The aerated concrete billet passes through the middle of the frame 1, and the cutting mechanism 2 cuts the aerated concrete billet during the passage.

[0041] Furthermore, such as Figure 4As shown, the cleaning assembly 211 also includes bearing mounting seats 2116 installed on the front and rear sides of the column of the frame 1, bearings 2117 correspondingly disposed on the bearing mounting seats 2116 and used to install the hollow spindle 2111, bearing pressure plates 2118 installed on the bearing mounting seats 2116 and pressing the outer ring of the bearings 2117, locking nuts 2119 threadedly disposed on the rear side of the hollow spindle 2111 and abutting against the inner ring of the bearings 2117 on the rear side, pressure rings 21110 disposed on the hollow spindle 2111 and abutting against the inner ring of the bearings 2117 on the front side, and a power pair 2110 for driving the hollow spindle 2111 to rotate.

[0042] It should be noted that the bearing 2117 is a tapered roller bearing, and the cooperation of the two sets of bearings 2117 makes the rotation of the hollow main shaft 2111 more stable.

[0043] Furthermore, such as Figure 2 As shown, the power pair 2110 includes a gear a21101 coaxially connected to the hollow main shaft 2111, a motor mounting plate a21102 mounted on the column of the frame 1, a motor a21103 mounted on the motor mounting plate a21102, and a gear b21104 mounted on the motor a21103 and meshing with the gear a21101.

[0044] It should be noted that the rotational speed of the hollow main shaft 2111 driven by the motor a21103 is adapted to the moving speed of the steel wire 22, thereby ensuring that every position on the steel wire 22 can be covered by the water spray nozzle 2112 and the air jet nozzle 2113.

[0045] Furthermore, such as Figure 4 As shown, the hollow spindle 2111 includes a spindle body 21111, a plurality of permeable holes a21112 formed on the spindle body 21111, two sets of baffles 21113 set at both ends of the spindle body 21111, and through holes a21114 and b21115 respectively formed on the corresponding baffles 21113 and coaxial with the spindle body 21111. The through holes a21114 are arranged toward the aerated concrete passage path, and the through holes b21115 are arranged toward the winding and unwinding assembly 212.

[0046] Furthermore, the stop block 21113 is arranged in a conical funnel shape toward the inner side of the main shaft body 21111.

[0047] It should be noted that the shape of the baffle 21113 ensures that the water sprayed from the nozzle 2112 will not flow out from the through hole a21114 and the through hole b21115.

[0048] Furthermore, the through hole b21115 is clearance-fitted with the steel wire 22, and the diameter of the through hole b21115 is larger than the diameter of the through hole a21114.

[0049] It should be noted that when the cut steel wire 22 enters the spindle body 21111 after cutting, the steel wire 22 first passes through the through hole a21114. The through hole a21114 is relatively large, so even if the steel wire 22 is covered with a lot of dirt, it can still enter the spindle body 21111.

[0050] It should also be noted that when the steel wire 22 passes through the through hole b21115 after being cleaned inside the spindle body 21111, the through hole b21115 can scrape off the water stains on the steel wire 22.

[0051] Furthermore, such as Figure 5 As shown, the sliding sleeve 2114 includes a sliding sleeve body 21141, a rotating joint 21142 rotatably mounted at both ends of the sliding sleeve body 21141 and respectively connected to external water supply and air supply equipment, a water permeable hole b21143 opened on the sliding sleeve body 21141, and a pipe 21144 disposed in the sliding sleeve body 21141 and connecting the water spray nozzle 2112 and the air spray nozzle 2113 and the corresponding rotating joint 21142.

[0052] It should be noted that the rotary joint 21142 is connected to the external water and gas supply equipment through a rigid pipe, thereby ensuring that water and gas can smoothly enter the pipe 21144. Furthermore, the rotary joint 21142 is existing technology, and its structure and principle will not be described in detail here.

[0053] It should also be noted that when the sliding sleeve body 21141 moves, one of the pipes 21141 is connected to the water nozzle 2112, while the other pipe 21141 is not connected to the air nozzle 2113, and vice versa.

[0054] It is worth mentioning that the sliding sleeve body 21141 and the main shaft body 21111 are slidably sealed, and water in the main shaft body 21111 can be discharged through the water-permeable hole a21112 and the water-permeable hole b21143.

[0055] Furthermore, the extending directions of the water nozzle 2112 and the air nozzle 2113 are consistent with the moving direction of the steel wire 22.

[0056] It should be noted that during cutting, the steel wire 22 enters the hollow main shaft 2111 immediately after leaving the aerated concrete blank. The stains attached to it have not yet deeply adhered to the steel wire 22. At this time, it is more convenient to rinse the steel wire 22. Therefore, the water nozzle 2112 and the air nozzle 2113 do not need too much pressure, so the steel wire 22 will not shake.

[0057] It should also be noted that the shapes of the jet nozzle 2112 and the water nozzle 2113 are matched with the moving speed of the steel wire 22, so that all areas of the steel wire 22 can come into contact with the medium.

[0058] Furthermore, such as Figure 3 and Figure 6 As shown, the drive pair 2115 includes a fixing bar 21151 circumferentially disposed on the sliding sleeve body 21141, a mounting plate 21152 disposed on the side of the column of the frame 1, a slider slide rail pair 21153 disposed on the mounting plate 21152, a shift fork 21154 disposed on the slider slide rail pair 21153 and locked on the fixing bar 21151, a cylinder mounting seat 21155 disposed on the mounting plate 21152, and a cylinder 21156 disposed on the cylinder mounting seat 21155 and whose power output end is connected to the shift fork 21154.

[0059] It should be noted that the shift fork 21154 will not affect the rotation of the sliding sleeve body 21141 with the main shaft body 21111.

[0060] Furthermore, the winding and unwinding assembly 212 includes a mounting platform 2121 mounted on the outside of the column of the frame 1, a wheel 2122 rotatably mounted on the mounting platform 2121 via a bracket and capable of winding the steel wire 22, a motor mounting plate b2123 disposed on the mounting platform 2121, a motor b2124 disposed on the motor mounting plate b2123, and a gear transmission unit 2125 that powerly connects the power output shaft of the motor b2124 and the wheel 2122.

[0061] It should be noted that the motor b2124 drives the wheel 2122 to rotate through the gear transmission unit 2125, thereby enabling the winding or unwinding of the steel wire 22.

[0062] Work process:

[0063] The motors b2124 on both sides rotate in coordination, causing one set of wheel discs 2122 to wind up the steel wire 22 and the other set of wheel discs 2122 to unwind the steel wire 22. The aerated concrete billet is cut as it passes through the steel wire 22. The power pair 2110 drives the main shaft body 21111 to rotate. The drive pair 2115 on the winding side drives the sliding sleeve body 21141 to move. The corresponding pipe 21144 is connected to the water spray nozzle 2112. The drive pair 2115 on the unwinding side drives the sliding sleeve body 21141 to move. The corresponding pipe 21144 is connected to the air spray nozzle 2113. The steel wire 22 cut on the winding side enters the main shaft body 2 from the aerated concrete billet and is rinsed by the water spray nozzle 2112. The steel wire 22 on the unwinding side is dried by several sets of air spray nozzles 2113 and then cuts the aerated concrete billet.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
