Description

Technical Field

[0001] The utility model relates to the field of flame arrester equipment production, and more specifically to a flame arrester core production equipment. Background Art

[0002] Flame arrester is a safety device used to prevent the spread of flames of flammable gases and flammable liquid vapors. It is generally installed in pipelines that transport flammable gases or on ventilated tanks to prevent the spread of flames (deflagration or detonation). It consists of a flame arrester core, a flame arrester shell and accessories.

[0003] Commonly used are metal mesh filter elements and corrugated filter elements. Metal mesh filter elements are made of stainless steel or copper mesh with a diameter of 0.23 to 0.315 mm, and are composed of multiple layers. Domestic flame arresters usually use 16 to 22 mesh metal mesh, which is 4 to 12 layers. Its working principle: One of the necessary conditions for combustion is to reach a certain temperature, that is, the ignition point. Below the ignition point, the combustion will stop. According to this principle, as long as the temperature of the burning material is reduced below its ignition point, the spread of the flame can be prevented. When the flame passes through many small channels on the fire-retardant core, it will become several small flames. The pipe wall on the fire-retardant core contacts the small flame, strengthens the heat transfer, and reduces the flame temperature below the ignition point, thereby preventing the flame from spreading.

[0004] According to different pipe diameter requirements, multiple fire-retardant cores can be stacked to meet the design requirements. Figure 1 As shown in the figure, the structure of the fire-blocking core is: the core shaft, the spacer and the corrugated belt are alternately wound into a circle. The small channel formed between the corrugated belt and the spacer is to take away the heat of the flame and thus reduce the combustion temperature to achieve the effect of fire blocking and extinguishing.

[0005] In the prior art, the fire-blocking core is produced by manually winding spacer tape and corrugated tape. This production method has the following defects:

[0006] 1. Low production efficiency;

[0007] 2. The product precision is low, especially in the outer diameter of the fire-retardant core. Due to manual winding, the dimensional processing precision of the outer diameter of the fire-retardant core is low;

[0008] 3. The winding pressure between the spacer belt and the corrugated belt is inconsistent, resulting in looseness between the spacer belt and the corrugated belt, which in turn causes uneven small channels and poses a safety hazard. Utility Model Content

[0035] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0036] In the description of the present utility model, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meaning of the terms can be understood according to the specific circumstances.

[0037] like Figure 2 and Figure 3 As shown, the fire-blocking core production equipment described in the utility model includes: a frame 1, a first unwinding mechanism 2, a second unwinding mechanism 3, a forming mechanism 4, a tension mechanism 5, a detection mechanism 6 and a winding mechanism 7. The first unwinding mechanism 2 and the second unwinding mechanism 3 are arranged at one end of the frame 1, the forming mechanism 4 is installed on one side of the second unwinding mechanism 3, at least one group of tension mechanisms 5 are installed on the side of the forming mechanism 4 away from the second unwinding mechanism 3, the winding mechanism 7 is arranged on the side of the tension mechanism 5 away from the forming mechanism 4, the detection mechanism 6 is arranged on the winding mechanism 7, and a plurality of transition wheels 8 are distributed between the first unwinding mechanism 2, the second unwinding mechanism 3, the forming mechanism 4, the tension mechanism 5, the detection mechanism 6 and the winding mechanism 7. The spacer tape is unwound by the first unwinding mechanism 2, the corrugated tape to be processed is unwound by the second unwinding mechanism 3, the optical tape is directly processed into a corrugated tape that meets the requirements by the forming mechanism 4, the tension of the corrugated tape is adjusted by the tension mechanism 5 to ensure that the finished product is tightly wound and not loose, the winding of the corrugated tape on one side of a layer of optical tape of the fire-blocking core is achieved by the winding mechanism 7, and the size parameters of the fire-blocking core are accurately controlled by the detection mechanism 6.

[0038] In the prior art, the winding pressure between the spacer and the corrugated belt is inconsistent, resulting in looseness between the spacer and the corrugated belt, which in turn leads to uneven fine channels, thus posing a safety hazard. The reason for the safety hazard is that the channels that should be fine in the design requirements become fine gaps due to insufficient pressure during winding, which reduces the absorption of heat and may pose a safety hazard. On the other hand, since the spacer and the corrugated belt are wound loosely, the entire surface will sink in an arc during transportation or use. If the entire spacer and the corrugated belt fall out, they are essentially unusable.

[0039] The structure of the first unwinding mechanism 2 is the same as that of the second unwinding mechanism 3. The first unwinding mechanism 2 and the second unwinding mechanism 3 are arranged in parallel. The stainless steel strip raw material is unwound by the first unwinding mechanism 2 and the second unwinding mechanism 3.

[0040] like Figure 4 As shown, the first unwinding mechanism 2 includes: a first support plate 21, a fixed shaft 22, a pressing sleeve 23, a connecting sleeve 24, a first connecting seat 25, a connecting rod 26, a second connecting seat 27 and a supporting block 28. The bottom of the first support plate 21 is installed on the top of the frame 1 through a bearing, and the first support plate 21 can rotate on the top of the frame 1. The fixed shaft 22 vertically installs the center of the first support plate 21. The outer wall of the fixed shaft 22 is provided with a thread. The pressing sleeve 23 is provided with an internal thread and meshes with the external thread on the fixed shaft 22. The connecting sleeve 24 is installed on the bottom of the fixed sleeve. The first connecting seat 25 is provided with at least 2 and is installed on the outer wall of the connecting sleeve 24. The supporting block 28 is provided with at least 2. The second connecting seat 27 is installed on the inner side of the supporting block 28. One end of the connecting rod 26 is hinged to the first connecting seat 25, and one end of the connecting rod 26 is hinged to the second connecting seat 27. Through the threaded connection between the pressing sleeve 23 and the fixed shaft 22 , the pressing sleeve 23 is rotated to enable the support block 28 to move toward or away from the fixed shaft 22 , thereby achieving the fixing and unwinding of the stainless steel coil.

[0041] The first connecting seat 25 and the second connecting seat 27 are both U-shaped, and the ends of the connecting rod 26 are inserted into the first connecting seat 25 and the second connecting seat 27 and are hinged to the first connecting seat 25 and the second connecting seat 27 through a rotating shaft.

[0042] During use, when the stainless steel coil is installed, the support block 28 is close to the fixed shaft 22, which is convenient for the installation of the stainless steel coil. In this state, the axial angle between the connecting rod 26 and the fixed shaft 22 is small; after the stainless steel coil is placed, the pressing sleeve 23 is rotated to drive the connecting sleeve 24 to move downward, and then the axial angle between the connecting rod 26 and the fixed shaft 22 gradually increases, so that the end of the connecting rod 26 is away from the fixed shaft 22, and finally drives multiple support blocks 28 away from the fixed shaft 22 to contact and fix with the inner roll of the stainless steel coil.

[0043] The number of the first connecting seat 25, the connecting rod 26, the second connecting seat 27 and the supporting block 28 is the same, and the outer side of the supporting block 28 is an arc supporting surface. The multiple supporting blocks 28 facilitate better fixation with the stainless steel coil, and the contact area between the arc supporting surface and the stainless steel coil is larger. In the implementation process, the number of the first connecting seat 25, the connecting rod 26, the second connecting seat 27 and the supporting block 28 is optimally set to 4, and the uniform distribution facilitates the force when supporting and fixing.

[0044] like Figure 5As shown, the forming mechanism 4 includes: a moving part 41, a first forming wheel 42, a second forming wheel 43 and a driving part 44. The first forming wheel 42 is installed below the moving part 41, and the second forming wheel 43 is installed at the output end of the driving part 44. The moving part 41 drives the first forming wheel 42 to move closer to and away from the second forming wheel 43. The distance between the first forming wheel 42 and the second forming wheel 43 is controlled by the moving part 41 to control the size of the small channel, and the stainless steel is driven by the driving part 44 to move to realize the processing of stainless steel with corrugations.

[0045] The moving part 41 includes: a first motor 411, a first linear rail 412, a first slider 413, a screw rod 414, a nut seat 415 and a sliding plate 416. The output end of the first motor 411 is connected to the screw rod 414, the first linear rail 412 is arranged on both sides of the screw rod 414, the first slider 413 is sleeved on the first linear rail 412, the nut seat 415 is sleeved on the screw rod 414, the sliding plate 416 connects the first slider 413 and the nut seat 415, and the first forming wheel 42 is installed at one end of the sliding plate 416 away from the first motor 411. The sliding plate 416 is driven by the first motor 411 to reciprocate on the first linear rail 412 to control the distance between the first forming wheel 42 and the second forming wheel 43. A mounting seat is arranged on the sliding plate 416 to set the first forming wheel 42, and it is necessary to ensure that the first forming wheel 42 rotates smoothly.

[0046] The driving part 44 is a second motor, the outer wall of the first forming wheel 42 has concave-convex straight teeth, the outer wall of the second forming wheel 43 has concave-convex straight teeth, the first forming wheel 42 is meshed with the second forming wheel 43, and the first motor 411 and the second motor are both servo motors. The stainless steel belt is pressed into a tooth shape through the concave-convex straight teeth on the surface to form a small channel. After the fire-blocking core is assembled, the corrugation contacts the spacer belt to form a triangular small channel.

[0047] like Figure 6 As shown, the tension mechanism 5 includes: a third motor 51, a first slide slot 52, a second slide slot 53, a second linear rail 54, a second slider 55 and a mounting plate 56. The first slide slot 52 and the second slide slot 53 are arranged in parallel on the frame 1. The second linear rail 54 is installed on the back of the frame 1. The second linear rail 54 is arranged between the first slide slot 52 and the second slide slot 53 and is parallel to the first slide slot 52 and the second slide slot 53. The second slider 55 is sleeved on the second linear rail 54. The mounting plate 56 is fixedly connected to the second slider 55. The third motor 51 is connected to the mounting plate 56 through a belt; the mounting plate 56 is pulled by the rotation of the third motor 51 to ensure the tension during winding.

[0048] A first guide wheel 57 is installed at one end of the mounting plate 56, and a second guide wheel 58 is installed at the other end of the mounting plate 56. The first guide wheel 57 is arranged in the first slide groove 52 and can reciprocate in the first slide groove 52, and the second guide wheel 58 is arranged in the second slide groove 53 and can reciprocate in the second slide groove 53;

[0049] A transition wheel 8 is provided at one end of the first slide groove 52, and a transition wheel 8 is provided at one end of the second slide groove 53; during actual use, the formed corrugated belt passes through the first guide wheel 57, the transition wheel 8 at the end of the first slide groove 52, the second guide wheel 58, the transition wheel 8 at the end of the second slide groove 53 in sequence, and then extends to the winding mechanism 7 through the transition wheel 8 on the side of the winding mechanism 7.

[0050] The third motor 51 is a servo motor. The third motor 51 and the belt pull the mounting plate 56 to ensure that the tension is consistent, so that the corrugated belt has a certain tension when winding, and the finished fire-blocking core is tightly wound. In the specific implementation process, the winding speed of the winding mechanism 7 and the pushing speed of the forming mechanism 4 cannot be completely consistent. The winding speed of the winding mechanism 7 is too fast to ensure the tension of the corrugated belt. Therefore, the third motor 51 does not run. If the winding speed of the winding mechanism 7 is lower than the pushing speed of the forming mechanism 4, it will inevitably cause the tension of the corrugated belt to be too small and the finished product to be loose. At this time, the sensor monitors the position of the mounting plate 56 and feeds back to the control panel, and then the third motor 51 runs to ensure the tension of the corrugated belt.

[0051] like Figure 7 As shown, the winding mechanism 7 includes: a pressing part 71, a second supporting plate 72, a reel 73 and a fourth motor 74. The bottom of the second supporting plate 72 is mounted on the top of the frame 1. A mounting hole 75 is arranged at the center of the second supporting plate 72. The fourth motor 74 is mounted on the back of the frame 1. The reel 73 passes through the mounting hole 75 and is connected to the output end of the fourth motor 74. The fourth motor 74 drives the reel 73 to rotate, and the pressing part 71 is close to the reel 73.

[0052] The pressing part 71 includes: a mounting shaft 711, a driving member 712, a connecting arm 713 and a pressing wheel 714. The bottom of the fixed shaft 22 is mounted on the frame 1. One end of the connecting arm 713 is connected to the top of the mounting shaft 711. The other end of the connecting arm 713 is connected to the reel 73. The pressing wheel 714 is arranged at the output end of the driving member 712 and the driving pressing wheel 714 is close to the reel 73.

[0053] The driving member 712 is a cylinder or a spring, and the pressing wheel 714 is arranged in the track inside the connecting arm 713 through a mounting member. The pressing wheel 714 is pressed against the reel 73 and rotates on the surface of the reel 73 through the cylinder or the spring. The fourth motor 74 is a servo motor.

[0054] The fourth motor 74 is connected to the reel 73 through a speed reducer. The tension of the spacer belt and the corrugated belt is consistent and not loose when the pressing part 71 is corrected during winding, and the fourth motor 74 drives the reel 73 to rotate to realize the winding of the spacer belt and the corrugated belt to form a finished fire-retardant core.

[0055] The detection mechanism 6 includes: a mounting bar 61 and a distance sensor 62. The mounting bar 61 is arranged on the top of the frame 1. The distance sensor 62 is arranged on the mounting bar 61, and the distance sensor 62 is aligned with the reel 73. The distance sensor 62 can accurately detect the winding thickness of the spacer tape and the corrugated tape during the winding process, so as to meet the requirement of high dimensional accuracy of the finished fire-blocking core.

[0056] In the actual operation process of the utility model, a control panel is arranged to set and control the parameters of the forming mechanism 4, the tension mechanism 5, the detection mechanism 6 and the winding mechanism 7 through a programmable controller.

[0058] S1: Place the stainless steel coil on the first unwinding mechanism 2, rotate the pressing sleeve 23 to drive the connecting sleeve 24 to move downward, and then the axial angle between the connecting rod 26 and the fixed shaft 22 gradually increases, so that the end of the connecting rod 26 is away from the fixed shaft 22, and finally drives the multiple support blocks 28 away from the fixed shaft 22 to contact and fix with the inner roll of the stainless steel coil;

[0059] S2: Place the stainless steel coil on the second unwinding mechanism 3, rotate the pressing sleeve 23 to drive the connecting sleeve 24 to move downward, and then the axial angle between the connecting rod 26 and the fixed shaft 22 gradually increases, so that the end of the connecting rod 26 is away from the fixed shaft 22, and finally drives the multiple support blocks 28 away from the fixed shaft 22 to contact and fix with the inner roll of the stainless steel coil;
