Description

Barrier explosion-proof material and preparation method thereof Technical Field

[0001] The present invention relates to the technical field of explosion-proof materials, and in particular to a barrier explosion-proof material and a preparation method and a production device thereof. Background Art

[0002] During the transportation and storage of some flammable and explosive products, explosion-proof materials are placed in the storage tanks to block flames and release energy in order to ensure the safety of transportation and storage. For example, barrier explosion-proof materials are placed in the oil tanks at oil depots and gas stations, the oil tanks of oil tank trucks, and the fuel tanks of various vehicles, as well as in hazardous chemical storage tanks. Existing barrier explosion-proof materials are generally columnar structures with equal cross-sections along their axial direction, such as polygonal or circular structures. In addition, the volume of the barrier explosion-proof material itself will occupy a lot of space in the tank, resulting in a limited amount of barrier explosion-proof material in the tank, reducing the explosion suppression effect of the tank. On the other hand, the barrier explosion-proof material will greatly compress the storage space in the tank, indirectly increasing the cost of use.

[0003] During the production of barrier and explosion-proof materials, the explosion-proof coils need to be subjected to various manual operations, which is time-consuming, labor-intensive, and inefficient. Therefore, how to achieve automated production of barrier and explosion-proof materials has become an urgent problem for researchers in this field.

The purpose of the process transfer device is to facilitate the transfer of intermediate products.

[0027] In one scheme of the present invention, the explosion-proof winding is arranged at the end of the frame, and the explosion-proof roll is transported by the conveying mechanism. At this time, the explosion-proof roll is unwound, and the explosion-proof roll passes through the conveying mechanism to form a flat explosion-proof material. During this process, the slitting mechanism acts on the explosion-proof material to cut the flat explosion-proof material to form strip-shaped explosion-proof material. The strip-shaped explosion-proof material passes through the extension mechanism to extend and stretch the explosion-proof material to form holes on the surface of the explosion-proof material. The strip-shaped explosion-proof material is then wound by the winding mechanism. At this time, multiple explosion-proof materials are synchronously wound on the winding mechanism, and the explosion-proof material is wound to form a columnar structure. The explosion-proof material is then cut by the cutting mechanism to separate the columnar structure and the strip-shaped explosion-proof material. Finally, the explosion-proof material is laterally pulled out of the winding mechanism by the robot, thereby realizing the automated winding, slitting and stretching of the explosion-proof material.

[0031] In this solution, multiple active conveyor belts are connected to the third bracket and rotate under the control of the motor. Spacers are placed between the two active conveyor belts to prevent the strip-shaped explosion-proof materials from interfering with each other during the extension process. The passive conveyor belt is set on the fourth bracket. Driven by the second cylinder, the passive conveyor belt is close to the active conveyor belt. The passive and active conveyor belts form a gap for the strip-shaped explosion-proof materials to move.

[0032] It should be noted that the rotation speed of the active conveyor belt is greater than the rotation speed of the active roller, so that the explosion-proof material can be stretched and extended.

[0035] How to fix the end of the explosion-proof material to the rotating shaft? The present invention adopts a rotating shaft comprising: a body, whose two ends are respectively connected to the fixed seat and the movable seat assembly; a clip, whose end is connected to the body near one end of the fixed seat; when the body and the clip are in a normal state, the body and the clip are tilted and form a gap for clamping the end of the explosion-proof material; the rotating shaft is composed of the body and the clip, and a gap is formed between the body and the clip for clamping the end of the explosion-proof material, thereby clamping the end of the explosion-proof material and the rotating shaft;

[0036] How to close the main body and the clip. The winding mechanism adopted by the present invention also includes: two partition plates, both sides of which are slidably connected to the frame and are located above or below the rotating shaft; a fourth cylinder, which is fixedly connected to the frame, and its output end is connected to the corresponding partition plate; an extrusion plate is provided on the side of the partition plate close to the rotating shaft, and an anti-channeling plate is protruded between the two extrusion plates; the two partition plates are driven by the fourth cylinder to approach or move away, and when approaching, the anti-channeling plate is inserted between the two columnar structures to prevent interference between the winding of the two, and the end of the anti-channeling plate acts on the main body or the clip, so that the main body or the clip closes and clamps the end of the explosion-proof material; the function of the extrusion plate is to limit the winding diameter of the columnar structure during the winding process of the columnar structure.

[0037] In order to illustrate the specific structure of the movable seat assembly in the winding mechanism, in a specific scheme, the present invention adopts a movable seat assembly including: a base, which is slidably arranged on the frame and moves perpendicular to the axial direction of the rotating shaft; a rotating shaft, which is controlled by the driving motor to be rotated and arranged on the base, and a clamping block is provided at its end; when the main body and the clip are closed, the end of the rotating shaft forms a groove for the insertion of the clamping block; the base moves linearly toward or away from the end of the rotating shaft, and the end of the rotating shaft rotatably arranged on the base is provided with a clamping block, which is driven by the movement of the base and is inserted into the groove formed at the end after the main body and the clip are closed, so that the rotating shaft rotates to realize the rotation of the rotating shaft; in this way, both ends of the rotating shaft are provided with a rotating force to realize the rotation of the rotating shaft; the base is movable, so that when the columnar structure is wound, the groove body and the clamping block are separated, and the columnar structure can be axially pulled out from the rotating shaft, which is convenient for moving the columnar structure to the next process.

[0038] In order to ensure that the rotational force at both ends of the rotating shaft is consistent, the present invention adopts a drive motor provided at the bottom of the frame; the rotational force of the drive motor is transmitted through a transmission shaft and then through both ends of the transmission shaft to the ends of the rotating shaft and the rotating shaft respectively;

[0039] In this solution, the transmission shaft is rotated and arranged at the bottom of the frame. The output end of the drive motor is connected to the transmission shaft through a synchronous belt. One end of the transmission shaft is connected to one end of the rotating shaft through a synchronous belt, and the other end is connected to the other end of the rotating shaft through a commutator and a synchronous belt. This ensures that the rotational force at both ends of the rotating shaft is consistent.

[0040] The advantages of the slitting and extending winding device are: the explosion-proof winding is arranged at the end of the frame, and the explosion-proof roll is transported by the conveying mechanism. At this time, the explosion-proof roll is unwound, and the explosion-proof roll passes through the conveying mechanism to form a flat explosion-proof material. In this process, the slitting mechanism acts on the explosion-proof material to cut the flat explosion-proof material to form strip-shaped explosion-proof material. The strip-shaped explosion-proof material passes through the extending mechanism to extend and stretch the explosion-proof material, forming holes on the surface of the explosion-proof material, and then the strip-shaped explosion-proof material is wound through the winding mechanism. At this time, multiple explosion-proof materials are synchronously wound on the winding mechanism, and the explosion-proof material is wound into a columnar structure. The explosion-proof material is then cut by the cutting mechanism to separate the columnar structure and the strip-shaped explosion-proof material. Finally, the explosion-proof material is laterally pulled out of the winding mechanism by the robot, realizing the automatic winding, slitting and extending of the explosion-proof material.

[0042] The columnar structure after winding is moved to the fixing mechanism of this device through the clamping hand, and the columnar structure is fixed to prevent expansion. The wire feeding mechanism moves from the upper rear side of the columnar structure to the upper front side and descends. At this time, the wire taking mechanism also moves from the lower rear side of the columnar structure to the lower front side and ascends. The wire taking mechanism clamps the end of the bundling wire transported by the wire feeding mechanism, and the wire feeding mechanism and the wire taking mechanism are reset. At this time, it is equivalent to the bundling wire being wrapped around the columnar structure once, and the end of the bundling wire and the bundling wire at the wire feeding mechanism are handed over to the knotting machine. At this time, the second cutting mechanism cuts the bundling wire, and the knotting machine works to wrap and fix the two ends of the bundling wire to prevent expansion. Finally, the fixing mechanism is released and handed over to the clamping hand for transportation to the next process, thus completing the automated bundling and packaging of the columnar structure.

After the handover of the tying wire end is completed, it is reset and then the tying wire is handed over to the knotting machine.

[0048] In order to illustrate the specific structure of the clamping block, the present invention adopts a notch provided on the inner side surface of the clamping block for clamping the binding wire; the end of the binding wire can be clamped and fixed through the notch.

Through the connecting rod connection, the upper hole body of the connecting rod is connected to the connecting protrusion on one of the slides, and the waist hole on the other end of the connecting rod is connected to the connecting protrusion on the other slide. In this way, when the twelfth cylinder is working, the outermost slide can be driven inward by the connecting piece so that multiple connecting protrusions are located on the same side of the waist hole. At this time, there is no gap between the multiple slides, or the outermost slide is driven outward so that multiple connecting protrusions are located on the other side of the waist hole. At this time, there are gaps between the multiple slides. In this state, interference between the column explosion-proof parts is avoided during the flipping of the clamp assembly.

[0056] In order to illustrate the specific structure of the rotating mechanism, in a specific scheme, the rotating mechanism adopted by the present invention includes: a rotating part, which is fixedly arranged at the end of the rotating shaft; a rotating protrusion, which is arranged at the end of the rotating part and is eccentrically arranged with the axis of the rotating shaft; a lifting part, a groove for accommodating the rotating protrusion is opened on the inner side of the lifting part; a thirteenth cylinder, which is fixedly arranged on the slide base plate, and its protruding end is connected to the lifting part; when the thirteenth cylinder is working, the linear motion of the lifting part is converted into the rotational motion of the rotating part through the rotating protrusion, thereby realizing the clockwise or counterclockwise rotation of the rotating shaft; the thirteenth cylinder drives the lifting part to perform lifting and lowering motion, the rotating protrusion of the rotating part is located in the groove, and the groove rises, realizing the clockwise or counterclockwise rotation of the rotating part, and then realizing the clockwise or counterclockwise movement of the rotating shaft, and then switching the spherical barrier explosion-proof material of the column from a horizontal state to a vertical state.

[0057] In order to illustrate the specific structure of the forming mechanism, in a specific scheme, the forming mechanism adopted by the present invention includes: a lifting frame, which is slidably connected to both sides of the support frame; a fourteenth cylinder, which is fixed on the base plate or the top of the support frame, and its protruding end is connected to the lifting frame; a motor, which is fixed on the lifting frame; a plurality of pressure rods, which are arranged correspondingly up and down, and are rotatably arranged on the lifting frame, and the ends of which are provided with the hemispherical groove structure; the motor drives the plurality of pressure rods to rotate synchronously; when the two fourteenth cylinders are working, the two lifting frames approach each other, and the two hemispherical groove structures synchronously extrude the vertical spherical barrier explosion-proof material, and during the extrusion process During the process, the motor starts, and the hemispherical groove structure rotates with the pressure rod, reducing the generation of burrs on the surface of the spherical barrier explosion-proof material; the lifting frame is provided with two upper and lower ones, and they are driven by the fourteenth cylinder to lean against each other, and the hemispherical groove structure at the end of the pressure rod squeezes the columnar spherical barrier explosion-proof material to fit the inner wall structure of the hemispherical groove structure; in the process of the pressure rod pressing down, the motor transmits the rotational force to each pressure rod in the form of synchronous wheels and synchronous belts, so that the pressure rod rotates during the downward process. In other words, the spherical barrier explosion-proof material is subjected to both the pressure and the rotational force of the hemispherical groove structure, which can reduce the generation of burrs on the surface of the spherical barrier explosion-proof material.

[0058] The advantage of the forming device in the present invention is that when the columnar structure is transported to the device by the clamping hand, the columnar structure is in a horizontal columnar state. The columnar structure is fixed by the clamp assembly, and the multiple clamp assemblies are separated by the adjustment structure to give the columnar spherical barrier explosion-proof material space to flip over. The columnar spherical barrier explosion-proof material is switched from a horizontal state to a vertical state by the rotating mechanism. Then, the two forming mechanisms act on the top and bottom of the columnar structure respectively to compress the columnar structure between the two hemispherical groove structures to form a spherical barrier explosion-proof material. After the compression is completed, the forming mechanism is reset, the clamp assembly is loosened and reset, and the spherical barrier explosion-proof material is loosened. At this time, the spherical barrier explosion-proof material is unloaded, achieving the purpose of squeezing the columnar spherical barrier explosion-proof material into a spherical barrier explosion-proof material.

[0059] To illustrate the specific structure of the process transfer device, in a specific embodiment, the process transfer device used in the present invention includes: a slide rail base; a sliding base slidably connected to the slide rail base and movable along the slide rail base in the Y-axis direction; a first slide plate slidably disposed on top of the sliding base and movable along the X-axis direction under the drive of a fifteenth cylinder; The support plate is vertically fixed on the end of the first slide; the first movable claw; it slides vertically on the end surface of the support plate, and is controlled by the sixteenth cylinder to move in the Z-axis direction, wherein the sixteenth cylinder is fixed on the top of the support plate; the second movable claw slides vertically on the end surface of the support plate, and is arranged relative to the first movable claw up and down, and is controlled by the seventeenth cylinder to move in the Z-axis direction, wherein the seventeenth cylinder is fixed on both sides of the support plate; the second slide plate is slidably arranged on the top of the first slide plate, and is controlled by the eighteenth cylinder to move in the X-axis direction; the third connecting rod is fixedly connected to the second slide plate, and a tightening plate is provided at its end through the support plate; when the second movable claw and the first movable claw are controlled by the corresponding cylinder to clamp the spherical barrier explosion-proof material, the tightening plate located between the second movable claw and the first movable claw moves in the X-axis direction to tighten the spherical barrier explosion-proof material.

[0060] In this way, under the control of the corresponding cylinder, the second movable claw and the first movable claw can realize three-axis linear motion and clamp the spherical barrier explosion-proof material. In order to make the spherical barrier explosion-proof material more firmly fixed between the second movable claw and the first movable claw, a tightening plate is provided between the second movable claw and the first movable claw along the X-axis direction. The tightening plate acts on a side surface close to the slide rail seat, which can fix the spherical barrier explosion-proof material more firmly.

[0061] In a specific solution, 10 pairs of second movable jaws and first movable jaws may be provided, and every two pairs of second movable jaws and first movable jaws can clamp a spherical barrier explosion-proof material.

[0062] The beneficial effects of the present invention are:

[0063] When the barrier explosion-proof material of the present invention is used, the material body is rolled into a structure with small ends and large middle by metal foil, and more material body is filled in a storage tank of the same volume. At the same time, the material body is a porous structure, which greatly increases the storage capacity of the storage tank and improves the explosion suppression effect of the material body, avoiding the problem that the volume of the existing barrier explosion-proof material itself takes up a lot of space in the tank, resulting in a limited amount of barrier explosion-proof material in the tank, reducing the explosion suppression effect of the tank body, and the surface barrier explosion-proof material greatly compresses the storage space in the tank, indirectly increasing the cost of use. The preparation method and production device of the barrier explosion-proof material provided by the present invention can quickly and automatically produce barrier explosion-proof materials on a large scale, which can save a lot of manpower and greatly improve production efficiency. The barrier explosion-proof material produced by the preparation method and production device of the barrier explosion-proof material provided by the present invention can realize the mechanized installation, removal and cleaning of the barrier explosion-proof material, completely solving the safety hazards caused by the confined space operation during the installation, removal and cleaning of the barrier explosion-proof material, and achieving intrinsic safety; in addition, the barrier explosion-proof material can be reused for a long time after cleaning, achieving the purpose of saving costs.

DETAILED DESCRIPTION

[0094] The present invention can be better understood according to the following examples. However, it is easy for those skilled in the art to understand that the contents described in the examples are only used to illustrate the present invention, and should not and will not limit the present invention described in detail in the claims.

[0095] The present invention is not limited to the following specific embodiments. Based on the disclosure of this invention, a person skilled in the art can adopt a variety of other specific embodiments to implement the present invention. Any simple changes or modifications made to the design structure and concept of this invention fall within the scope of protection of this invention. It should be noted that the embodiments and features of the embodiments of this invention can be combined with each other unless there is a conflict.

[0096] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0097] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0098] The explosion-proof material in the present invention generally refers to metal foil, which can be made of aluminum or aluminum alloy.

[0099] The material body of the present invention can be a sphere, a spheroid, an ellipsoid, a spherical table or a spherical table. For the sake of convenience, we also refer to the material body as a spherical barrier explosion-proof material.

[0100] The cross-section of the material body in the present invention refers to a cross-section along the center of the sphere when the material body constitutes a sphere, a spheroid, an ellipsoid, a spherical table or a spherical table. The middle of the cross-section is the middle of the columnar structure when the material body is formed, and the two ends of the cross-section are the two ends of the columnar structure. Therefore, the cross-sectional area of ​​the material body is larger in the middle and smaller at both ends. The two ends can be as small as a short line, or as small as the two ends combined to form a point or an arc.

[0101] As shown in Figures 23-25, a barrier explosion-proof material includes a material body 1. The material body 1 is rolled into a column by metal foil 2, and then a metal wire (i.e., a fixing ring 5) is wound around the column of the material body 1 by an external device. Then, another device presses the two ends of the column of the material body 1 into shape, that is, the cross-sectional area of ​​the material body 1 is larger in the middle and smaller at both ends.

[0102] The metal foil 2 has a honeycomb-like pore 3 structure and forms a porous structure on the formed material body 1. The honeycomb structure on the metal foil 2 is formed by multiple groups of slits 4 arranged in an array. Each group of slits 4 is composed of multiple spaced slits 4. The slits 4 between two adjacent groups of slits 4 are staggered and then formed by stretching the metal foil 2.

[0103] The shaping mechanism is a fixing ring 5 that is clamped on the material body 1. The fixing ring 5 is located at the large end of the cross section of the material body 1. The fixing ring 5 is a metal wire wound on the material body 1, which realizes the shaping mechanism to prevent the material body 1 from loosening.

[0104] In a specific embodiment, the diameter of the material body is 30-100 mm, the thickness of the metal foil is 0.05-0.075 mm, the length of the slit is 15-20 mm, and the single hole diameter of the honeycomb pore structure is 7-14 mm.

[0105] When the above-mentioned barrier explosion-proof material is in use, the material body 1 is placed in a storage tank. Since the material body 1 is large in the middle and thin at both ends, more material bodies 1 can be placed in the storage tank, thereby improving the explosion suppression effect of the storage tank. Moreover, the material body 1 itself has a porous structure, which has a good explosion suppression effect on the one hand, and does not affect the storage capacity of the storage tank on the other hand.

[0106] The barrier explosion-proof material prepared by the present invention was subjected to blasting equipment quality inspection, and the test results are as follows:

[0107] The present invention includes a method for preparing the above-mentioned barrier and explosion-proof material, which comprises: first cutting a plurality of strip-shaped pores spaced apart on a metal foil, then stretching and elongating the metal foil to form honeycomb-shaped pores on the surface of the metal foil, then winding it into a columnar structure, using a fixing ring to tie it in the middle of the columnar structure, and squeezing the two ends of the columnar structure to form a shape with a larger middle and smaller ends.

[0108] The present invention includes a more specific method for preparing a barrier explosion-proof material, which comprises: using a slitting, extending and winding device to unwind, slit, extend and wind an explosion-proof roll made of explosion-proof material metal foil to form a columnar structure; using a bundling mechanism to bundle a bundling wire in the middle of the columnar structure to form a fixed ring; and using a forming device to squeeze the two ends of the columnar structure to form a shape that is larger in the middle and smaller at both ends.

[0109] The present invention includes a production device for preparing the above-mentioned barrier explosion-proof material, which includes: a slitting, extending and winding device, which is suitable for unwinding, slitting, extending and winding the explosion-proof roll to form a columnar structure; a bundling mechanism, which is suitable for bundling the columnar structure; a forming device, which is suitable for extruding the columnar structure into a spherical structure and unloading it; a process transfer device, which is suitable for transporting the columnar structure from the slitting, extending and winding device to the bundling mechanism, or transporting the columnar structure at the bundling mechanism to the forming device.

[0110] The present invention is a device for producing barrier explosion-proof materials, comprising a slitting, extending and winding device 100, a bundling mechanism 200 and a forming device 300 which are arranged in sequence; the slitting, extending and winding device 100 is suitable for unwinding, slitting, extending and winding explosion-proof rolls to form a columnar structure; the bundling mechanism 200 is suitable for bundling the columnar structure; the forming device 300 is suitable for squeezing the columnar structure into a spherical barrier explosion-proof material and unloading it; the process transfer device 400 is suitable for transporting the spherical barrier explosion-proof material from the slitting, extending and winding device 100 to the bundling mechanism 200, or transporting the spherical barrier explosion-proof material at the bundling mechanism 200 to the forming device 300; the function of the process transfer device is to facilitate the transportation of spherical barrier explosion-proof materials.

[0111] To illustrate the structure of the slitting, extending and winding device, as shown in Figures 1-3 and 7, the slitting, extending and winding device 100 includes: a frame 101; an explosion-proof roll 102, which is wound with an explosion-proof material 103 and is mounted at the entrance end of the frame 101; a conveying mechanism 104, which is arranged on the frame 101 and is suitable for driving the explosion-proof material 103 to be flatly transported; a slitting mechanism 105, which is arranged at the conveying mechanism 104 and is suitable for cutting the explosion-proof material 103 into strip structures An extension mechanism 106 is provided on the frame 101 and is located behind the conveying mechanism 104, and is suitable for extending and stretching the explosion-proof material 103 after slitting; a winding mechanism 107 is provided at the exit of the frame 101, and is suitable for synchronously winding the strip-shaped explosion-proof material 103 to form a plurality of columnar structures 108; a cutting mechanism 109 is provided between the winding mechanism 107 and the extension mechanism 106, and is suitable for cutting the explosion-proof material 103;

[0112] In this solution, the explosion-proof winding is arranged at the end of the frame, and the explosion-proof roll is transported by the conveying mechanism. At this time, the explosion-proof roll is unrolled, and the explosion-proof roll passes through the conveying mechanism to form a flat explosion-proof material. During this process, the slitting mechanism acts on the explosion-proof material to cut the flat explosion-proof material to form strip-shaped explosion-proof material. The strip-shaped explosion-proof material passes through the extension mechanism to extend and stretch the explosion-proof material, forming holes on the surface of the explosion-proof material, and then the strip-shaped explosion-proof material is wound by the winding mechanism. At this time, multiple explosion-proof materials are synchronously wound on the winding mechanism, and the explosion-proof material is wound to form a columnar structure. The explosion-proof material is then cut by the cutting mechanism to separate the columnar structure from the strip structure explosion-proof material. Finally, the explosion-proof material is laterally pulled out of the winding mechanism by a robot arm (not shown in the figure), thereby realizing the automated winding, slitting and extension of the explosion-proof material.

[0113] As shown in Figures 1-3, in order to illustrate the specific structure of the conveying mechanism, the present invention adopts a conveying mechanism 105 including: a second bracket 110, which is fixedly arranged on the frame 101; a plurality of active rollers 111, which are rotatably arranged on the second bracket 110 and are controlled by a motor to rotate synchronously; a plurality of driven rollers 112, which are arranged above the active rollers 111 and are rotatably connected to the first bracket 113; a first cylinder 114, whose cylinder body is fixedly connected to the frame 101 and whose protruding end is connected to the first bracket 113; when the first cylinder 114 is working, the plurality of driven rollers 112 approach the active roller 111, and the driven rollers 112 and the active rollers 111 clamp the explosion-proof material 103 and drive the flattened explosion-proof material 103 to be transported;

[0114] The second bracket is fixed on the frame, and multiple active rollers are rotatably arranged in the second bracket. The first bracket is located above the second bracket and is controlled to rise and fall by the first cylinder. A driven roller is arranged on the second bracket. The action of the first cylinder drives the driven roller close to the active roller, and a gap is formed between the driven roller and the active roller for the explosion-proof material to pass through. The active roller is controlled to rotate by the motor, and driven by friction, it can flatly transport the explosion-proof material to the extension mechanism.

[0115] As shown in Figures 1-3, in order to illustrate the specific structure of the slitting mechanism, the present invention adopts a slitting mechanism 104 including: a plurality of cutters 115, which are arranged at the bottom of the first bracket 113; when the driven roller 112 approaches the active roller 111, the plurality of cutters 115 act on the flat explosion-proof material 103 to cut the explosion-proof material 103 into strip structures;

[0116] In this way, when the driven roller descends, the cutter descends synchronously and acts on the surface of the explosion-proof material. In this way, the cutter can cut the explosion-proof material during the movement of the flattened explosion-proof material and cut the explosion-proof material into a strip structure.

[0117] As shown in Figures 1 and 4, in order to illustrate the specific structure of the extension mechanism, the present invention adopts an extension mechanism 106 including: a third bracket 116, which is fixedly arranged on the frame 101; a plurality of active conveyor belts 117, which are rotated at intervals on the third bracket 116 and are controlled by a motor to rotate synchronously; a plurality of spacers 118, which are fixedly arranged on the third bracket 116 and are located between the two active conveyor belts 117; a fourth bracket 119, which is arranged above the third bracket 116, and has a plurality of passive conveyor belts 120 arranged thereon; a second cylinder 121, whose cylinder body is fixedly connected to the frame 101, and its protruding end is connected to the fourth bracket 119; when the second cylinder 121 works, it drives the passive conveyor belt 120 to approach the active conveyor belt 117, presses and transports the cut explosion-proof material 103, increases the speed of the active conveyor belt 117, and stretches and extends the explosion-proof material 103;

[0118] In this solution, multiple active conveyor belts are connected to the third bracket and rotate under the control of the motor. Spacers are placed between the two active conveyor belts to prevent the strip-shaped explosion-proof materials from interfering with each other during the extension process. The passive conveyor belt is set on the fourth bracket. Driven by the second cylinder, the passive conveyor belt is close to the active conveyor belt. The passive and active conveyor belts form a gap for the strip-shaped explosion-proof materials to move.

[0119] It should be noted that the rotation speed of the active conveyor belt is greater than the rotation speed of the active roller, so that the explosion-proof material can be stretched and extended.

[0120] As shown in FIG3 , in order to illustrate the specific structure of the cutting mechanism, the present invention adopts a cutting mechanism 109 comprising: a cutting blade 122, one side of which is hinged to the frame 101; a third cylinder 123, one end of which is hinged to the top of the frame 101 and the other end is connected to the cutting blade 122; when the third cylinder 123 is in operation, the cutting blade 122 rotates and acts on the explosion-proof material 103, thereby cutting the explosion-proof material 103;

[0121] In the process of the explosion-proof material being transported from the extension mechanism to the winding mechanism, a cutting mechanism is provided. When the explosion-proof material is wound to form an explosion-proof roll, the third cylinder works, the angle between the cutting knife and the frame decreases, the cutting knife acts on the explosion-proof material, and cuts off the explosion-proof material.

[0122] As shown in Figures 5-6, in order to illustrate the specific structure of the winding mechanism, the present invention adopts a winding mechanism 107 including: a fixed seat 124, which is fixed to the frame 101; a movable seat assembly 125, which is slidably arranged on the frame 101; a rotating shaft, whose two ends are respectively rotatably connected to the movable seat assembly 125 and the fixed seat 124, and the explosion-proof material 103 is wound thereon; a driving motor, which is connected to the rotating shaft at one end of the fixed seat 124;

[0123] The two ends of the rotating shaft are rotatably connected to the fixed seat and the movable seat assembly respectively. The driving motor drives the rotating shaft to rotate, fixes the end of the strip-shaped extended explosion-proof material to the rotating shaft, and rotates the rotating shaft to wind the explosion-proof material into a columnar structure.

[0124] As shown in FIG6 , how to fix the end of the explosion-proof material to the rotating shaft, the present invention adopts a rotating shaft comprising: a body 126, whose two ends are respectively connected to the fixed seat 124 and the movable seat assembly 125; a clip 127, whose end is connected to the body 126 near one end of the fixed seat 124; when the body 126 and the clip 127 are in a normal state, the body 126 and the clip 127 are tilted and form a gap 128 for clamping the end of the explosion-proof material 103;

[0125] The rotating shaft is composed of a body and a clip. A gap is formed between the body and the clip for clamping the end of the explosion-proof material, thereby clamping the end of the explosion-proof material and the rotating shaft.

[0126] As shown in FIG5 , how to close the body and the clip, the present invention adopts a winding mechanism 107 further comprising: two partition plates 129, both sides of which are slidably connected to the frame 101 and are located above or below the rotating shaft; a fourth cylinder 130, which is fixedly connected to the frame 101, and its output end is connected to the corresponding partition plate 129; a squeezing plate 130 is provided on the side of the partition plate 129 close to the rotating shaft, and an anti-channeling plate 131 is protruded between the two squeezing plates 130;

[0127] Driven by the fourth cylinder, the two partition plates move closer or farther away. When they move closer, the anti-channeling plate is inserted between the two columnar structures to prevent interference in their winding. The end of the anti-channeling plate acts on the main body or the clamp, so that the main body or the clamp closes and clamps the end of the explosion-proof material; the function of the extrusion plate is to limit the winding diameter of the columnar structure during the winding process.

[0128] As shown in FIG5 , in order to illustrate the specific structure of the movable seat assembly, the present invention adopts a movable seat assembly 125 comprising: a base 133, which is slidably disposed on the frame 101 and moves perpendicularly to the axis of the rotating shaft; a rotating shaft 134, which is controlled by the driving motor to rotate and is disposed on the base 133, and a clamping block 135 is provided at its end; when the body 126 and the clip 127 are closed, the end of the rotating shaft forms a groove 136 for inserting the clamping block 135;

[0129] The base moves linearly toward or away from the end of the rotating shaft. A clamping block is provided at the end of the rotating shaft rotatably arranged on the base. Driven by the movement of the base, the clamping block is inserted into the groove formed at the end of the body and the closed rear end of the clip. In this way, the rotating shaft rotates, which can realize the rotation of the rotating shaft. In this way, both ends of the rotating shaft are provided with a rotating force to realize the rotation of the rotating shaft.

The output end of the drive motor is connected to the transmission shaft through a synchronous belt. One end of the transmission shaft is connected to one end of the rotating shaft through a synchronous belt, and the other end is connected to the other end of the rotating shaft through a commutator and a synchronous belt.

It should also be noted that the binding roll is connected to the second vertical plate and moves synchronously with the second vertical plate. The power required for the binding wire on the binding roll is provided by the clamping block of the wire taking mechanism.

[0140] As shown in FIG12 , in order to illustrate the specific structure of the wire-taking mechanism, the wire-taking mechanism 208 of the present invention includes: a second sliding plate 224, which is slidably arranged on the second frame 201 and is controlled by the eighth cylinder 225 to slide along the X-axis direction; a ninth cylinder 226, which is fixed to the bottom of the second sliding plate 224; a lifting plate 227, which is arranged above the second sliding plate 224 and is controlled by the ninth cylinder 226 to move in the Z-axis direction; a vertical rod 228, which is arranged on the lifting plate 227, A clamping block 229 is hingedly provided at its top; a tenth cylinder 230, the cylinder body of which is hingedly connected to one side of the bottom of the vertical rod 228; a connecting rod 231, which is connected to the output end of the tenth cylinder 230, and its other end is hingedly connected to the clamping block 229; driven by the eighth cylinder 225 and the ninth cylinder 226, the vertical rod 228 can move in two axes in the Z-axis and X-axis directions; under the action of the tenth cylinder 230, the clamping block 229 can rotate towards or away from the vertical rod 228 to clamp or loosen the end of the binding wire;

[0142] It should be noted that when the end of the tying wire is handed over from the wire feeding mechanism to the wire taking mechanism, the two are in the upper and lower positions. After the end of the tying wire is handed over, it is reset and then handed over to the knotting machine.

[0143] As shown in FIG12 , in order to illustrate the specific structure of the clamping block, the present invention adopts a clamping block 229 with an inner side surface provided with a notch 232 for clamping the binding wire;

[0149] In this solution, 5 explosion-proof rolls can be bundled and packed synchronously, which improves the packaging efficiency.

[0150] To illustrate the specific structure of the forming device, as shown in Figures 15-16, a forming device 300 is used to extrude a columnar structure into a spherical, spheroidal, ellipsoidal, spherical table or spherical table-like spherical barrier and explosion-proof material. Taking the spherical explosion-proof barrier material as an example, the forming device 300 includes: a base plate 301; a support frame 302, which is fixed on the base plate 301; a plurality of clamp assemblies 303, which slide horizontally on the support frame 302, and are suitable for clamping the columnar structure 108; an adjustment mechanism, which is suitable for adjusting the plurality of clamp assemblies 303 to a gapless or gapped state; a rotation mechanism, which is suitable for switching the clamp assemblies 303 together with the columnar structure 108 between a horizontal or vertical state; two forming mechanisms 305, which are respectively arranged at the top and bottom of the support frame 302, and the protruding ends thereof are provided with a hemispherical groove structure 306; when the clamp assembly 303 drives the columnar structure 108 to switch to a gapped and vertical state, the two forming mechanisms 305 approach each other, and the hemispherical groove structure 306 acts on the top and bottom of the columnar structure 108 respectively, compressing the columnar structure 108 and forming a spherical structure;

[0151] In this solution, when the spherical barrier explosion-proof material with a columnar structure is transported to the device by the clamping hand, the spherical barrier explosion-proof material is in a horizontal columnar state. The columnar structure is fixed by the clamp assembly, and the multiple clamp assemblies are separated by the adjustment structure to give the columnar spherical barrier explosion-proof material space to flip over. The columnar spherical barrier explosion-proof material is switched from a horizontal state to a vertical state by the rotating mechanism. Subsequently, the two forming mechanisms act on the top and bottom of the spherical barrier explosion-proof material respectively to compress the spherical barrier explosion-proof material between the two hemispherical groove structures to form a spherical barrier explosion-proof material. After the compression is completed, the forming mechanism is reset, the clamp assembly is loosened and reset, and the spherical barrier explosion-proof material is loosened. At this time, the spherical barrier explosion-proof material is unloaded, thereby achieving the purpose of squeezing the columnar spherical barrier explosion-proof material into a spherical barrier explosion-proof material.

[0152] As shown in Figures 15-19, in order to illustrate the specific structure of the clamp assembly, the present invention adopts a clamp assembly 303 including: a slide base plate 307, which is fixed to the support frame 302; a slide 308, the bottom of which is slidably connected to the slide base plate 307; a rotating shaft 309, which is rotatably connected to the corresponding slide 308; a clamp body 310, which is connected to the end of the rotating shaft 309 and is provided with mutually adjacent claws 311;

[0153] In this solution, multiple slides are slidably arranged on the slide base plate, a rotating shaft is rotatably arranged on the slide, a clamp body is arranged at the end of the rotating shaft, and two claws are arranged at the end of the clamp body. The clamp body controls the approach of the two claws to clamp the cylindrical spherical barrier explosion-proof material.

[0154] As shown in Figures 17-18, to illustrate the specific structure of the adjustment mechanism, the present invention adopts an adjustment mechanism comprising: a twelfth cylinder 312, which is fixedly disposed at the bottom of the sliding base plate 307; a connecting member 313, which is connected to the protruding end of the twelfth cylinder 312 and passes through the sliding base plate 307 to connect to the bottom of one of the sliding seats 308; connecting protrusions 314, which are disposed on both sides of the top of each sliding seat 308; a plurality of connecting rods 315, which connect two adjacent connecting protrusions 314 on two adjacent sliding seats 308; wherein, a hole 316 is formed on one end of each connecting rod 315, and a waist hole 317 is formed on the other end.

[0155] In this way, the two adjacent connecting protrusions on the two adjacent slides are connected by a connecting rod, the upper hole of the connecting rod is connected to the connecting protrusion on one of the slides, and the waist hole on the other end of the connecting rod is connected to the connecting protrusion on the other slide. In this way, when the twelfth cylinder is working, the outermost slide can be driven inward by the connecting piece so that multiple connecting protrusions are located on the same side of the waist hole. At this time, there is no gap between the multiple slides, or the outermost slide is driven outward so that multiple connecting protrusions are located on the other side of the waist hole. At this time, there is a gap between the multiple slides. In this state, interference between the column explosion-proof parts is avoided during the flipping of the clamp assembly.

[0156] As shown in Figures 17-18, in order to illustrate the specific structure of the rotating mechanism, the rotating mechanism adopted by the present invention includes: a rotating member 318, which is fixedly arranged at the end of the rotating shaft 309; a rotating protrusion 319, which is arranged at the end of the rotating member 318 and is eccentrically arranged with respect to the axis of the rotating shaft 309; a lifting member 320, the inner side of which is provided with a long strip-shaped groove 322 for accommodating the rotating protrusion; a thirteenth cylinder 321, which is fixedly arranged on the slide base plate 307, and its protruding end is connected to the lifting member 320; when the thirteenth cylinder 321 is working, the linear motion of the lifting member 320 is converted into the rotational motion of the rotating member 318 through the rotating protrusion 319, thereby realizing the clockwise or counterclockwise rotation of the rotating shaft 309;

[0157] The thirteenth cylinder drives the lifting part to perform lifting movements. The rotating protrusion of the rotating part is located in the groove, and the groove rises, realizing the clockwise or counterclockwise rotation of the rotating part, and then realizing the clockwise or counterclockwise movement of the rotating shaft, and then switching the spherical barrier explosion-proof material of the column from a horizontal state to a vertical state.

[0159] There are two lifting frames, one above and one below, which are driven by the fourteenth cylinder to lean against each other, and the hemispherical groove structure at the end of the pressure rod squeezes the columnar spherical barrier explosion-proof material to fit the inner wall structure of the hemispherical groove structure; during the downward pressing process of the pressure rod, the motor transmits the rotational force to each pressure rod through the synchronous wheel and synchronous belt (not shown in the figure), so as to realize the rotation of the pressure rod during the downward process. In other words, the spherical barrier explosion-proof material is subjected to both the pressure and the rotational force of the hemispherical groove structure, which can reduce the generation of burrs on the surface of the spherical barrier explosion-proof material.

[0160] As shown in Figure 15, this solution can achieve synchronous compression of five spherical barrier explosion-proof materials. In Figure 1, in order to facilitate the understanding of the vertical and horizontal structures of the spherical barrier explosion-proof materials, in actual production, the states of multiple spherical barrier explosion-proof materials are synchronized;

[0161] In Figures 15, 16, and 19, the synchronous belt is omitted in order to show the synchronous wheel on the pressure rod.

[0162] As shown in Figures 20-21, in order to illustrate the specific structure of the process transfer device, the process transfer device 400 includes: a slide rail seat 401; a sliding seat 402, which is slidably connected to the slide rail seat 401 and moves along the slide rail seat 401 in the Y-axis direction; a first slide plate 403, which is slidably arranged on the top of the sliding seat 402 and moves along the X-axis direction under the drive of the fifteenth cylinder 404; a support plate 405, which is vertically fixed to the end of the first slide plate 403; a first movable claw 406; which slides vertically on the end surface of the support plate 405 and is controlled by the sixteenth cylinder 408 to move in the Z-axis direction, wherein the sixteenth cylinder 408 is fixed on the top of the support plate 405; a second movable claw 407, which slides vertically on the end surface of the support plate 405, and is arranged relatively to the first movable claw 406 in an upper and lower direction, and is controlled by the seventeenth cylinder 409 to move in the Z-axis direction, wherein the seventeenth cylinder 409 is fixed on both sides of the support plate 405; the second slide plate 410 is slidably arranged on the top of the first slide plate 403, and is controlled by the eighteenth cylinder 411 to move in the X-axis direction; the third connecting rod 412 is fixedly connected to the second slide plate 410, and its end passes through the support plate 405 and is provided with a tightening plate 413; when the second movable claw 407 and the first movable claw 406 are controlled by the corresponding cylinder to clamp the columnar structure 108, the tightening plate 413 located between the second movable claw 407 and the first movable claw 406 moves in the X-axis direction to tighten the columnar structure 108;

[0163] In this way, under the control of the corresponding cylinder, the second movable claw and the first movable claw can realize three-axis linear motion, and the spherical barrier explosion-proof material can be clamped. In order to make the spherical barrier explosion-proof material more firmly fixed between the second movable claw and the first movable claw, a tightening plate is provided between the second movable claw and the first movable claw along the X-axis direction, and the tightening plate acts on a side close to the slide rail seat, so that the spherical barrier explosion-proof material can be fixed more firmly; in this solution, as shown in Figures 20-21, 10 pairs of second movable claws and first movable claws are provided, and every two pairs of second movable claws and first movable claws can realize the clamping of a spherical barrier explosion-proof material.
