[0002] Fireproof mud is a fireproof sealing material used in places such as cable conduits, cable trays, and cable trenches.

[0003] During the continuous extrusion of the fireproof mud from the extrusion device, a cutting device is required to cut the long strips of fireproof mud. The existing cutting method cuts the fireproof mud by moving a thin steel cable up and down.

[0048] The mineral insulated cable fireproof mud preparation device includes the following working steps:

[0049] S1: conveying, the conveyor belt 1 transports the fireproof mud to the workbench 3;

[0050] S2: Extrusion and shaping: moving the pressing plate 5, the longitudinal extrusion block 6 and the transverse extrusion block 7 to extrude the fireproof mud to shape the fireproof mud;

[0051] S3: weighing, the fireproof mud after shaping is weighed by the intelligent weighing system inside the supporting plate 501;

[0052] S4: feeding and packaging, the push plate 503 pushes the weighed fireproof mud to make the fireproof mud enter the packaging mechanism 2 for packaging.

[0053] The working steps of this embodiment are:

[0054] After the fireproof mud is extruded from the existing extrusion device, the fireproof mud extruded into long strips is cut according to the set length by the existing cutting device, and the cut fireproof mud is placed flat on the conveyor belt 1 and transported to the workbench 3 by the conveyor belt 1.

[0055] As the conveyor belt 1 is transported, the right end of the fireproof mud will gradually rest on the pressing plate 5 of the workbench 3 until the fireproof mud can no longer be pushed by the conveyor belt 1. At this time, most of the right side of the fireproof mud is located on the workbench 3, while another small part rests on the conveyor belt 1, and the fireproof mud as a whole is located at the lower right of the left transverse extrusion block 7. The first electric slider 102 is controlled to drive the fixed block 4, the second slide rail 301, the second electric slider 302, the connecting block 401, the supporting block 402 and the transverse extrusion block 7 to move downward together until the transverse extrusion block 7 on the left is located on the left side of the fireproof mud. The second electric slider 302 is then controlled to drive the transverse extrusion block 7 to move to the right, so that the transverse extrusion block 7 slowly approaches the left end of the fireproof mud, and gradually pushes the fireproof mud to the right until the fireproof mud is located in the middle of the pressing plate 5.

[0056] When the fireproof mud is located in the middle of the pressing plate 5, the first electric slider 102 is continuously controlled to drive the fixed block 4 and the pressing plate 5 located above to move downward, and squeeze the upper side of the fireproof mud below, until the upper pressing plate 5 reaches the set position, the pressing plate 5 stops moving downward, and then the two power parts 201 are controlled to respectively drive the adjacent longitudinal extrusion blocks 6 to move toward one side of the fireproof mud, and squeeze the front and rear sides of the fireproof mud respectively, until the longitudinal extrusion block 6 moves to the set distance, the longitudinal extrusion block 6 stops moving, at this time, the pressing plate 5 and the longitudinal extrusion block 6 are pressed. The upper and lower sides and the front and rear sides of the fireproof mud are squeezed respectively to deform the fireproof mud. It should be noted that at this time, the two longitudinal extrusion blocks 6 are located between the upper and lower pressing plates 5. Finally, the second electric slider 302 is controlled to drive the adjacent connecting blocks 401 and the transverse extrusion blocks 7 to move to one side of the fireproof mud, and the left and right sides of the fireproof mud are squeezed. At this time, the two transverse extrusion blocks 7 are located between the front and rear longitudinal extrusion blocks 6 and the upper and lower pressing plates 5, and the fireproof mud is located in the rectangular cavity formed by the pressing plates 5, the longitudinal extrusion blocks 6 and the transverse extrusion blocks 7, as shown in FIG. Fig. 9 As shown, the device can extrude and shape the fireproof mud into a rectangular shape, ensuring that the shape and size of the fireproof mud are consistent, which is convenient for standardized production and packaging. At the same time, fireproof mud with consistent shape will be more convenient to use, and construction workers can quickly take and use it without the need for trimming and other operations, thereby improving construction efficiency.

[0057] When the fireproof mud is shaped, it is manually placed on the packaging mechanism 2 for packaging, thereby realizing the packaging of the fireproof mud. At the same time, the first electric slider 102, the power part 201 and the second electric slider 302 are controlled to drive the pressing plate 5, the longitudinal extrusion block 6 and the transverse extrusion block 7 back to the initial position respectively. Then, with the transportation of the conveyor belt 1, the right end of the next fireproof mud will gradually rest on the pressing plate 5 of the workbench 3, and then repeat the above operation to shape the fireproof mud in turn.

[0058] In the above process, after the fireproof mud is shaped, since the temperature of the fireproof mud is high when it is extruded from the extrusion device, there is a risk of burns when the shaped fireproof mud is manually placed in the packaging mechanism 2. At the same time, the shaped fireproof mud has not been completely solidified and still has the ability to deform. It is difficult to control the strength during the manual picking process, so it is easy to damage the shaped fireproof mud and affect the overall appearance. In order to solve the above problem, when the fireproof mud is shaped, the third electric slider 602 is controlled to drive the support plate 501, the support table 502 and the fireproof mud on the pressing plate 5 to move downward, so that the fireproof mud enters the feed port 3 of the workbench 3. 002, until the upper surface of the pressing plate 5 is flush with the lower side of the discharge port 3003 on the right side of the workbench 3, and then the fourth electric slider 604 is controlled to drive the push plate 503 to move toward the side of the discharge port 3003, thereby pushing the fireproof mud to move toward the discharge port 3003, until the fireproof mud is pushed out of the workbench 3, the fireproof mud will be placed on the packaging mechanism 2 on the right, and the packaging shaping paper wrapped on the winding roller 2001 on the packaging mechanism 2 drives the fireproof mud to continue to move to the right to the packaging area, and finally completes the packaging, so that there is no need for manual labor to personally pick up the fireproof mud that has just been shaped, which reduces the risk of scalding and reduces the workload of manual labor.

[0059] It should be noted that before the fireproof mud is packaged, it is usually necessary to manually place the fireproof mud on an electronic scale and weigh the fireproof mud to ensure that the weight of each piece of fireproof mud is consistent and to ensure the standardization and consistency of the product. However, manual weighing is inefficient and the fireproof mud is easily damaged during the picking process. To solve the above situation, the fireproof mud is weighed through the intelligent weighing system inside the support plate 501 after the fireproof mud is shaped, and the weight data of the fireproof mud is transmitted to the touch screen 504 for display. The fireproof mud is manually judged based on the data on the touch screen 504 to see whether it meets the standards. If it does not meet the standards, it will be taken out and placed in a special recycling device for unified processing. The fireproof mud that meets the standards will be transported to the packaging mechanism 2, so there is no need to manually pick up and weigh them one by one, thereby improving product production efficiency.

[0060] At the same time, different construction scenarios and needs require fireproof mud of different shapes. For example, rectangular fireproof mud is suitable for scenarios such as cable trenches and cable wells. The regular shape is convenient for filling irregular spaces to ensure the sealing effect. The cylindrical fireproof mud is suitable for scenarios such as cable pipes and cable joints. It matches the circular cross-section and will provide good sealing and fire protection. In order to improve the adaptability of the device, when the user needs to shape the fireproof mud into a cylindrical shape, when the fireproof mud is located in the middle of the pressing plate 5, the first electric slider 102 is controlled to drive the fixed block 4 and the pressing plate 5 located above to move downward to the set position, so that the pressing plate 5 located above squeezes the upper side of the fireproof mud, and then all the first driving members 701 are controlled to drive the bending blocks 702 to move toward one side of the fireproof mud, so that the bending blocks 702 squeeze the adjacent pressing plates 5 respectively, so that the pressing plates 5 gradually deform, and finally the pressing plates 5 are bent into a semi-ring shape. At this time, the two pressing plates 5 are attached to each other and form a complete cylindrical tube, such as Figure 8 As shown, the fireproof mud between the two pressing plates 5 is squeezed and shaped into a regular long strip.

[0061] At this time, the left and right ends of the fireproof mud are still irregular shapes, and the second electric sliders 302 on the left and right sides are controlled to drive the connecting block 401, the supporting block 402, the spring telescopic rod 403 and the transverse extrusion block 7 to move toward one side of the fireproof mud. Taking the transverse extrusion block 7 on the right as an example, the transverse extrusion block 7 will gradually approach the right side of the cylindrical pressing plate 5 until the transverse extrusion block 7 is squeezed by the right sides of the two pressing plates 5. It should be noted that the diameter of each circular plate 7001 is consistent with the inner diameter of the cylinder composed of the upper and lower pressing plates 5. At this time, the second electric slider 302 continues to drive the supporting block 402 to move to the left. 7001 is slidably connected to the transverse extrusion block 7, and the circular plate 7001 is fixedly connected to the support block 402 through a round rod. Therefore, after the transverse extrusion block 7 is squeezed by the right side of the pressing plate 5 combined in a cylindrical shape, it will drive the spring telescopic rod 403 to contract, so that the transverse extrusion block 7 and the telescopic end of the spring telescopic rod 403 move to the right together, and the circular plate 7001 enters the interior of the cylinder composed of the two pressing plates 5, so that the two circular plates 7001 squeeze the left and right sides of the fireproof mud respectively, so that the fireproof mud is shaped into a cylinder, thereby meeting the needs of product diversification and improving the adaptability and convenience of the device.

[0062] At the same time, it should be noted that the pressing plate 5, the longitudinal extrusion block 6 and the transverse extrusion block 7 are all detachable, and their sizes can be changed according to user needs, thereby further improving the adaptability and convenience of the device.

[0063] When the fireproof mud is shaped, the first driving member 701 is controlled to drive the bending block 702 to return to the initial position, so that the pressing plate 5 returns to a straight state, and then the above-mentioned feeding steps are repeated to transport the shaped fireproof mud to the packaging mechanism 2.

[0064] Example 2

[0065] On the basis of Example 1, Figure 1 , Figure 2 , Fig.10 and Fig.11 As shown, it also includes a second driving member 801 and a connecting strip 802; each support block 402 is fixedly connected to two front-to-back symmetrical second driving members 801, and the second driving member 801 is an electric push rod; each circular plate 7001 is slidably connected to a connecting strip 802 through a round rod, and each connecting strip 802 is fixedly connected to the telescopic end of the adjacent second driving member 801; each connecting strip 802 is provided with four thin plates 80201, and each thin plate 80201 passes through the adjacent circular plates 7001.

[0066] Each thin plate 80201 on the connecting bar 802 is distributed in a vertical state.

[0067] Each thin plate 80201 is made of stainless steel.

[0068] It also includes an air outlet pipe 901; a plurality of air outlet pipes 901 are fixedly connected to the workbench 3, and each air outlet pipe 901 is connected to an external pump.

[0069] The working steps of this embodiment are:

[0070] It should be noted that in the process of preparing the fireproof mud, mixing and stirring are required. During the mixing and stirring, external gas will be brought in, resulting in bubbles inside the fireproof mud after it is extruded from the extrusion device. The presence of bubbles will affect the sealing of the fireproof mud. In order to improve the above situation, in the process of the pressing plate 5, the longitudinal extrusion block 6 and the transverse extrusion block 7 extruding and shaping the fireproof mud, the gas inside the fireproof mud after extrusion will be discharged. In order to improve the effect of discharging the gas inside the fireproof mud, when the second electric slider 302 drives the corresponding connecting block 401, the supporting block 402 and the transverse extrusion block 7 to approach the left and right sides of the fireproof mud respectively, as shown in FIG. Fig.10As shown, taking the right transverse extrusion block 7 as an example, the thin plate 80201 of the connecting strip 802 will contact the right side of the fireproof mud before the transverse extrusion block 7. Therefore, before the transverse extrusion block 7 is about to reach the set position and extrude the right side of the fireproof mud, the thin plate 80201 will gradually insert into the fireproof mud. After the transverse extrusion block 7 is about to reach the set position, the second driving member 801 is controlled to drive the connecting strip 802 to move rightward, so that the connecting strip 802 drives the thin plate 80201 to gradually detach from the fireproof mud, until the left side of each thin plate 80201 fits with the left side of the adjacent transverse extrusion block 7 and stops moving. At this time, the inside of the fireproof mud is filled with thin plates 80201 due to the thin plates 80201. 1 is inserted to form several exhaust channels, and then the power piece 201 is controlled to drive the adjacent longitudinal extrusion blocks 6 to extrude the front and rear sides of the fireproof mud, so that the gas inside the fireproof mud is directly discharged outward through the exhaust channels, thereby improving the gas exhaust effect. At the same time, with the movement of the longitudinal extrusion block 6, the exhaust channels inside the fireproof mud will also be gradually compacted, and the fine plates 80201 are distributed in a vertical state, so that the exhaust channels are also in a vertical state, and the extrusion force of the longitudinal extrusion block 6 in the front and rear directions is used to quickly compact the exhaust channels, thereby improving the compaction effect of the longitudinal extrusion block 6 on the exhaust channels, and preventing large holes from existing inside the fireproof mud and affecting subsequent use.

[0071] When the fireproof mud is shaped, since it has not been completely solidified when it is just squeezed out, it still has the ability to deform. In order to further avoid damage to the fireproof mud after shaping, when the third electric slider 602 drives the support plate 501, the support platform 502 and the fireproof mud on the pressing plate 5 to move downward, the external pump is started to make the air outlet pipe 901 blow air toward one side of the fireproof mud, accelerate the flow of air, enhance the cooling effect of the fireproof mud, thereby improving the curing efficiency of the fireproof mud, and preventing the push plate 503 from damaging the shaped fireproof mud when pushing the fireproof mud, thereby improving the aesthetics of the product.
