Description

Field of the Invention

The present invention relates to a processing equipment for explosion-proof material, in particular to a processing equipment for explosion-proof filling material installed in storage/transport vessel of combustible and explosive chemicals and a rolling-cutting and mesh-pulling synchronization control unit thereof.

Description of the Prior art

It is necessary to install explosion-proof filling materials in the storage-transport vessels for combustible and explosive liquid and/or gaseous chemicals, so as to prevent the medium stored in such vessels from combustion or explosion triggered by unexpected accidents such as static electricity, naked flame and gunshot etc. The manufacturing procedures for such explosion-proof material are described as follows: cutting the aluminum alloy foil material into a grid, gradually stretching both sides of such material outward to form a high porosity lamellar material; with a end of such high porosity lamellar material as center rolling it along the direction perpendicular to this end to get a multilayer cylindrical explosion-proof material body. The conventional processing equipment has been related in the Description of invention patent ZL02117070.3. The rolled up aluminum alloy foil material used in the conventional equipment is set on the material roll bracket at the upper part of a chassis. The material roll adopted for such equipment weights about 50 kilogram, which is a big load and leads to certain difficulty in manual installation and disassembly of the material roll. For conventional equipment, nonsynchronization of the rotation speeds of the rolling cutter drive motor of the cutting mechanism and the rotation speed of the mesh-pulling stretching drive motor of the mesh-pulling mechanism often occurs in the process of operating. While processing the explosion-proof material, the motor speed often changes making it necessary to regulate the motor frequently, which seriously restrain the production progress and the quality of finished products. During continuous cutting process of the conventional equipment, dust and material particles on the surface of aluminum foil are liable to block the cutting blade and blunt the blade, which in turn affects the cutting quality. In addition, the conventional equipment is provided with a manual cutter for cutting mesh material, so that it is difficult to control the roll size of finished material roll. Furthermore, after cutting the material roll, it is required to take out the material manually, which is inefficient and requires intense physical labor, and it even jeopardizes the potential safety of the operator.
To sum up, the conventional equipment has many defects such as low automation control level, low working efficiency, inferior product quality, high labor intensity and big potential safety hazard. Thus it needs to be improved.
CN 2 354 687 Y discloses a processing equipment for a new type of meshed material according to the pre-characterizing portion of claim 1. This equipment, however, does not comprise sufficient means for obtaining an end product whose quality is good enough.
WO 95/05 254 A1 discloses a device for producing homogenous spheres from so-called stretch material. An aluminum foil 1 is conveyed onto the processing device via a feeding reel 2. The foil 1 is cut by a cutting unit 6 and stretched by a stretching unit 5 and then rolled up by an end reel 7. The end reel 7 is directly driven by a motor 10 and it functions as the driving wheel, whereas the feeding reel 2 functions as a driven wheel with tensioning rollers 8, 9 arranged therebetween. In order to ensure a smooth running and continuous operation, the speed of the motor 10 is controlled. The control of the motor 10 is carried out in the following way: The tensioning rollers 8, 9 mounted between the cutting unit 6 and the stretching unit 5 are designed as sliding, non-driven rollers movable in approximately vertical guides between upper sensors 11, 11' and lower sensors 12, 12'. The weight of the tensioning rollers 8, 9 is selected depending on the material, the solidity and the thickness of the foil. The speed of the rotation of the motor 10 is regulated such that it is slowed down when the tensioning rollers 8, 9 reach the upper sensors 11, 11', whereas it is increased when the tensioning rollers 8, 9 reach the lower sensors 12, 12', in a manner that the tensioning rollers 8, 9 keep their positions between the sensors 11, 11' and 12, 12', respectively.

Detailed Description of the Preferred Embodiments

Embodiment 1

Figure 1 is the overall structural scheme of a preferred embodiment 1 of present invention. As shown in Figure 1, the present invention provides a processing equipment of explosion-proof material comprising a chassis 1, wherein, from one end to the other end of the chassis 1, a raw material roll bracket 2, a guide mechanism 3, a rolling-cutting mechanism 4 and a mesh-pulling mechanism 5 are respectively fixed in sequence and at intervals. A cutting and material-receiving mechanism 6 is fixed on the other end of the chassis 1. This equipment is mainly designed for the following manufacturing procedures for explosion-proof material: cutting the aluminum alloy foil material into grid shape by means of rolling-cutter mechanism 4, then, in the mesh-pulling mechanism, gradually stretching both sides of such material outward to form a high porosity lamellar material; with a end of such high porosity lamellar material as center, rolling it along the direction being perpendicular to this end to get a multilayer cylindrical explosion-proof material body.
With respect to the rolling-cutting mechanism of conventional equipment, since nonsynchronization of the rotation speed of rolling cutter drive motor 41 and he rotation speed of the mesh-pulling stretching drive motor 51 of the mesh-pulling mechanism often occurs in the process of operation, it is necessary to perform debugging after the equipment has operated for a short time. Especially in the manufacturing procedure, the motor speed changes frequently, so that it is necessary to make adjustment continually, which seriously confines the production progress and the quality of finished products. Therefore, as shown in Figure 1, in the present invention, a synchronization control unit 7 for the rolling-cutter drive motor and meshing-pulling device drive motor is set on the chassis between rolling cut mechanism 4 and the mesh-pulling mechanism 5. This synchronization control unit 7 is electrically connected with the regulating control box (not shown in the Figure) and inputs control signal to the regulating control box. The regulating control box is electrically connected with the rolling-cutter drive motor 41 and mesh-pulling stretching drive motor 51 and inputs control signals to regulate their rotation speeds so as to achieve synchronized operation of them.
Figure 2 is the local structural scheme of the synchronization control unit of embodiment 1 of present invention. As shown in Figure 2, the synchronization control unit 7 comprises a buffer roller frame 71 fixed on the chassis. This buffer roller frame 71 is composed of a pair of "T"-shaped vertical frames 711 and 712, between the corresponding top ends on each of them is installed a roller shaft (not shown in the Figure), on which is mounted a buffer sleeve 72. A locating slot 73 is set on the inner side of the upright column of the "T"-shaped vertical frame. A buffer rod 74 is set in this locating slot 73 and can slide up and down in this locating slot 73. A sensor 75 is set on the upright column of "T"-shaped vertical frames to detect the position of the buffering rod and can be installed on the outside surface of the upright column of "T" shaped vertical frame, the output end of sensors 75 being electrically connected with the input end of regulating control box. To achieve more accurate detection, a plurality of sensors 75 are respectively set on the upper, middle and lower positions of the upright column of "T"-shaped vertical frame. In general, XTFJ - R12 sensors can be adopted. When the equipment is in operation of processing the explosion-proof material, the buffering rod 74 is attached onto the upper surface of the processed material. In case of nonsynchronization of the rotation speeds of the rolling-cutter drive motor 41 and the mesh-pulling stretching drive motor 51, the stretching force applied on the materials on the buffer roller frame 71 varies, and the tension of the material varies accordingly. The buffer rod 74 attached onto the material slide up and down in the locating slot 73. When the buffering rod 74 is on the upper position of the buffer roller frame 71, the buffering rod 74 blocks the sensors 75 on the upper position of the buffer roller frame 71; When the buffer rod is on the lower position of the buffer roller frame 71, the buffer rod 74 blocks the sensors on the lower position of the buffer roller frame 71. The blocked sensors will output the sensing signals to the regulating control box, and the regulating control box will output the control signals, and by means of PLC regulating control system in the regulating control box, the rotation speeds of the rolling-cutter drive motor 41 and the mesh-pulling stretching drive motor 51 can be regulated, and so the synchronization can be achievable. By this time, the equipment should be in the optimum operation condition, and the buffer rod 74 should be located on the middle position. Since the synchronization control unit 7 achieves the synchronized operation of the drive motors, reliability of the equipment operation is greatly enhanced and the product quality is also improved.
As shown in Figure 1, the rolling cutter 42 in the rolling-cutting mechanism 4 is composed of a pair of slits-cutting rollers (namely upper and lower rollers). The upper roller is composed of multiple disk cutters, on each of which there is a blade and a groove. The lower roller is designed with corresponding discs. During the continuous cutting, the dust and material particles on the surface of aluminum foil are liable to block the cutter blade, so that the blades become blunt and the cutting quality is seriously affected. Figure 3 is the local structural scheme of the brush and oil dripping cup of embodiment 1 of present invention. As shown in Figure 3 in combination with Figure 1, to keep the cleanness and sharpness of rolling-cutter 42, a brush 43 is set at the upper portion of rolling-cutter roller bracket of the rolling-cutting mechanism 4 and can be used for removing dust and particles. To maintain the sharpness of blade, an oil dripping cup 44 is set above brush 43, with the oil-dripping hole of the oil dripping cup extending to the brush handle 45. An oil storage tank 46 is set inside the brush handle 45. A plurality of oil-dripping holes (not shown in the Figure) is set in the lower part of the oil storage tank 46 and connected with the brush. Along with the movement of brush 43, the cleansing oil in oil-dripping cup 44 provides dripping lubrication for the cutter through oil-dripping holes. In this way, the brush can conveniently remove the dust and material particles deposited on rolling cutter and keep the slits grid to be cut even and consistent.
Figure 4 is the local structural scheme of the synchronization control unit of embodiment 1 of present invention. As shown in Figure 4, a control valve is set in the oil dripping cup 44 for regulating or controlling the oil amount. This control valve comprises a valve core 442 connected with a rotation handle 441, the rotation handle 441 being set above the oil dripping cup 44 and extends out of the oil dripping cup 44. The end of valve core 442 is set corresponding to the position of oil-dripping hole outlet 443; The clearance between the end of core valve 442 and the oil-dripping hole outlet 443 can be regulated by turning the rotation handle 441, so that the oil output amount flowing from the oil dripping cup 44 into the brush handle is changed.
Meanwhile, as shown in Figures 1 and 3, to effectively remove the material particles generated by the rolling-cutting mechanism in the manufacturing procedure, a dust hood 47 is also set over the rolling-cutter 42 of the rolling-cutting mechanism 4, and this dust hood is connected with the external vacuum dust collector. During the processing of the raw aluminum alloy foil material, this dust hood 47 connected with the vacuum can effectively prevent the aluminum powder on aluminum foil from flying about and remove them so as to keep the working environment clean.
Figure 5 is the overall planform of the equipment of embodiment 1 of present invention. As shown in Figure 5 in combination with Figure 1, in the processing equipment provided in the present invention, the cutting and material-receiving mechanism 6 comprises a platform 611 fixed on the horizontal plane at the top of the chassis 1. A pneumatic sliding sleeve 613 and a sliding guide track 617 are mounted on the brackets 612 on both ends of the platform, wherein the pneumatic sliding sleeve is interconnected with the slipper 614, under which a supporting rod 615 is set; and a disk-shaped cutter 616 is mounted on the supporting rod 615. The pneumatic sliding sleeve and the sliding track are connected to a high-pressure gas source. A sliding part (not shown in the Figure) is set in the slipper 614. Under the action of high-pressure gas stream, the sliding part enables the slipper 614 to reciprocate along the sliding guide sleeve and sliding track. The slipper 614 drives the disc-shaped cutter 616 to roll on and cut off the finished product of mesh material. In general, the high-pressure gas filled in the pneumatic sliding sleeve has pressure of 7.5 KPa and gas flow rate of 0.22 M³ / minute. The pipe joint is a barbed joint with diameter of 8mm.
The operation mode of the conventional equipment is as follows: After manual cutting, the material should be manually taken out from the shaft of rolling mechanism. This operation mode involves high labor intensity and potential safety hazard. Figures 6, 7 and 8 are local structural schemes of the pneumatic pusher mechanism of embodiment 1 of present invention observed from three different views of. As shown in Figures 6-8 in combination with Figures 1 and 5, a supporting plate 621 is mounted under the platform outside of the end of chassis 1, a material-receiving reel 622 is threaded on the supporting plate 621. This material-receiving reel 622 is connected with the output shaft of rolling-up motor 624 on chassis 1 through a chain 623. The formed reticular material is wound on the material-receiving reel 622, and thus the multilayer cylindrical material body is obtained. A pneumatic material pusher mechanism 63 is set on said material-receiving reel 622, and it comprises a pneumatic sliding sleeve 631 and a sliding guide track 632 that are fixed under the platform 611. The pneumatic sliding sleeve 631 is interconnected with the slipper 633, the slipper 633 is connected with a pushing plate 634 fitted on the material receiving reel 622. A groove which is larger than the material-receiving reel 622 is fit on the front end of pushing plate 634 without contact with the shaft. The pneumatic sliding sleeve 631 is connected with the high-pressure gas source, and a sliding part (not shown in the Figure) is set inside the slipper 633. Under the action of high-pressure gas stream, this sliding part enables the slipper 633 to move along the sliding guide track 632, and the slipper 633 drives the pushing plate 634 to push the multilayer cylindrical explosion-proof material off the material-receiving reel 622. The high-pressure gas has pressure of 7.5 KPa and gas flow of 0.22 M³ / minute.
In the manufacturing procedures for explosion-proof material, the control on the pneumatic cutting, rolling and automatic material-pushing is performed according to the pre-setting of the counter installed on the shaft of slits-cutting roller. When the motor rotates for a circle, the counter records a pulse count. After the counts add up to the preset value, for example, 100 impulses, a roll of material is formed. After the material-receiving reel 622 has wound up a required roll of finished product, the regulating control box sends an instruction such as to stop the running of rolling-cutter drive motor 41 and the mesh-pulling stretching drive motor 51. Then, the relay starts the gas source for gas supplying, which drives the disc cutter of the rolling-cutting mechanism to cut off the roll of reticular explosion-proof material. Finally the pneumatic material pusher mechanism is activated, and it pushes off the explosion-proof material wound around the material-receiving reel, thus completing the processing of a roll of finished product material.
In addition, the roll of raw aluminum alloy material in the conventional equipment is set on the roll bracket at the upper part of the chassis, with the weight of a roll of raw foil material being about 20 kg. The rolled material of raw aluminum alloy foil material used at present has weight about 50kg, so that the working strength is very high in case of transporting or lifting the rolled material. Therefore, as shown in Figure 1 in combination with Figure 5, the roll bracket is set at the bottom of the chassis in the present invention, to be specific, the raw material roll bracket 2 is fixed under the outside of one end of chassis 1, so as to facilitate the loading and unloading of raw material roll. This raw material roll bracket 2 extends two long arms 21 outward, and bearing sleeves being set on the arm ends. The aluminum foil material with reel is placed on the forked standard of bearing. A friction assembly is installed on one side of forked standard of bearing, with the structure of this friction assembly being designed as identical to that of shaft brake assembly of bicycle, so that the unrolling procedure of rolled material is limited evenly and has certain damping. Through said improvements, the processing equipment of explosion-proof material provided by the present invention may reduce labor intensity and enhance working efficiency.

As shown in Figure 9, the structure of the pneumatic pusher mechanism set on the material receiving reel in this embodiment is different from embodiment 1 in some aspects. This pneumatic pusher mechanism 64 comprises a baffle 641 set on one end of the chassis. A cylinder 642 is fixed on the baffle 641, and a telescopic push rod 643 is set in the cylinder 642 passing through the baffle and connecting with a annular plate 644. This annular plate 644 is fitted above the material-receiving reel 622 and does not contact with the reel. The annular plate 644 is also connected with a guide bar 645 that passes through the baffle 641. The inlet pipe and outlet pipe of high-pressure gas are attached onto the cylinder 642 and are connected with gas source through high pressure-resistant hose. The high-pressure gas in the cylinder enables the telescopic push rod 643 move telescopically and drives the annular plate 644 to move on the material-receiving reel 622 along the guide bar 645, so as to push the multilayer cylindrical explosion-proof material body off the material-receiving reel, thus completing the material processing.
The other technical characteristics of this preferred embodiment are the same as those of embodiment 1. For the detailed content, refer to embodiment 1, and unnecessary details will no longer be provided herein.
