Abstract
Description
Technical Field
[0001] This application relates to the field of fireproof board production equipment, and more specifically to a quantitative conveying switch. Background Technology
[0002] In the production of fireproof boards, the conveying of foamed granules is crucial. Traditional conveying methods have several shortcomings. On the one hand, it is difficult to precisely control the amount of foamed granules conveyed, which may lead to inaccurate material ratios during production, affecting the quality of the fireproof boards. On the other hand, due to the special texture of foamed granules, they are prone to mutual compression and accumulation during conveying, causing poor conveying or even blockages, reducing production efficiency. In addition, traditional equipment may lack effective means to flexibly adjust the conveying volume and solve the problem of granule accumulation, failing to meet diverse production needs.
[0003] Therefore, a quantitative conveying switch is needed that can accurately control the amount of foamed particles conveyed, solve the problem of accumulation during the conveying process, and be easy and flexible to operate, so as to improve the quality and efficiency of fireproof board production. Summary of the Invention
[0004] To address the aforementioned technical problems, this application solves the issues of inaccurate control of the conveying volume of fireproof foam granules during transportation, and the difficulty in smooth transportation due to mutual compression and accumulation during transport.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a quantitative conveying switch, comprising a conveying pipe, wherein a mounting rod and an upper connecting ring are fixedly mounted on the conveying pipe, an outer control ring, an inner control ring and a lower connecting ring are rotatably mounted on the mounting rod, an iris component is provided on both the outer control ring and the upper connecting ring, an outer connecting ring is rotatably mounted on the conveying pipe, a fan is fixedly mounted on the outer connecting ring, an external threaded rod is provided on the fan, a hollow groove is provided on the external threaded rod, an inner control rod is rotatably mounted on the hollow groove, and four fans are provided on the external threaded rod, one of which is threadedly connected to the external threaded rod.
[0006] An outer slide rod is fixedly installed on the fan near the outer connecting ring. The outer slide rod has a hollow groove, and a spring is fixedly installed on the hollow groove. An inner slide rod is slidably installed on the end of the outer slide rod away from the outer connecting ring. Another outer slide rod is slidably installed on the end of the inner slide rod away from the outer connecting ring. This outer slide rod also has a spring installed on it. A fan is also fixedly installed on the end of this outer slide rod away from the outer connecting ring. A fan is fixedly installed on the inner slide rod. A fan is fixedly installed in the middle of the outer slide rod near the outer connecting ring.
[0007] To better realize this application, the four fans are further provided with two adjustment components, each including two outer slide rods, two springs and one inner slide rod, with the two outer slide rods and springs respectively located at both ends of the inner slide rod.
[0008] To better realize this application, the outer control ring is further fixedly connected to the external threaded rod, the inner control ring is fixedly connected to the inner control rod, the iris assembly on the inner control ring is rotatably connected to the inner control ring, the inner control ring is rotatably connected to the outer control ring, and the outer control ring is rotatably connected to the outer connecting ring.

[0013] The technical solution provided in this application has the following advantages compared with the prior art:

Detailed Implementation
[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0031] like Figures 1 to 9 As shown, a quantitative conveying switch includes a conveying pipe 101. A mounting rod 102 and an upper connecting ring 105 are fixedly mounted on the conveying pipe 101. An outer control ring 103, an inner control ring 104, and a lower connecting ring 113 are rotatably mounted on the mounting rod 102. An iris component 114 is provided on both the outer control ring 103 and the upper connecting ring 105. An outer connecting ring 108 is rotatably mounted on the conveying pipe 101. A fan 109 is fixedly mounted on the outer connecting ring 108. An external threaded rod 107 is provided on the fan 109. The external threaded rod 107 has a hollow groove. An inner control rod 106 is rotatably mounted on the hollow groove. Four fans 109 are provided on the external threaded rod 107, one of which is threadedly connected to the external threaded rod 107.
[0032] An outer slide rod 110 is fixedly installed on the fan 109 near the outer connecting ring 108. The outer slide rod 110 has a hollow groove, and a spring 111 is fixedly installed on the hollow groove. An inner slide rod 112 is slidably installed on the end of the outer slide rod 110 away from the outer connecting ring 108. Another outer slide rod 110 is slidably installed on the end of the inner slide rod 112 away from the outer connecting ring 108. A spring 111 is also installed on this outer slide rod 110. A fan 109 is also fixedly installed on the end of this outer slide rod 110 away from the outer connecting ring 108. A fan 109 is fixedly installed on the inner slide rod 112. A fan 109 is fixedly installed in the middle of the outer slide rod 110 near the outer connecting ring 108.
[0033] When in use, the hoisting device of this application is used for quantitative control of the conveying of fireproof foam granules. It is connected to the front-end conveying pipe through the upper connecting ring 105 and the rear-end feed port through the lower connecting ring 113, or directly aligned with the mixing chamber.
[0034] In use, the upper connecting ring 105 is opened by controlling the inner control rod 106 while keeping the lower connecting ring 113 closed. This allows the material in the conveying pipe to fall onto the lower connecting ring 113 and fill the conveying pipe 101. Once filled, the upper connecting ring 105 is closed to block the conveying pipe at the front end, thus achieving quantitative distribution of the foamed particles. Then, the lower connecting ring 113 is opened, and the foamed particles fall through the lower end of the lower connecting ring 113 by gravity and enter the mixing chamber. During this process, the external threaded rod 107 and the external connecting ring 108 are rotated synchronously, causing multiple fans 109 to rotate inside the conveying pipe 101. This agitates the foamed particles in each layer of the conveying pipe 101 and pushes them downwards, preventing accumulation and suspension due to mutual compression, and ensuring that the foamed particles are conveyed cleanly.
[0035] like Figures 2 to 4 As shown, the four fans 109 are equipped with two adjustment components. The adjustment components include two outer slide rods 110, two springs 111, and one inner slide rod 112. The two outer slide rods 110 and the springs 111 are respectively located at both ends of the inner slide rod 112.
[0036] Specifically, such as Figure 3 As shown, the lowest fan 109 and the outer connecting ring 108 are at the same horizontal height, and the lower end face of the outer slide rod 110 below the two adjustment components is fixedly connected to the upper end face of the fan 109. The lower end face of the uppermost fan 109 is fixedly connected to the upper end face of the outer slide rod 110 on the two adjustment components. The distance between the fan 109 in the middle of the spring 111 and the two outermost fans 109 is the same. The distance from the fan 109 on the lower outer slide rod 110 to the lower fan 109 is less than the distance of the middle fan 109.
[0037] When it is necessary to control the capacity of the foamed particles conveyed in the conveying pipe 101, the outer connecting ring 108 is fixed, and the external threaded rod 107 is controlled to rotate. This fixes the lowermost fan 109 through the outer connecting ring 108. The three upper fans 109 are connected to the lower fan 109 through the adjusting component, thus restricting the rotation of all four fans 109. The rotation of the external threaded rod 107 drives the uppermost fan 109 to move up and down on the external threaded rod 107 through the thread. This causes the uppermost fan 109 to drive the iris assembly 114, crossbar 115, and guide plate 116 in the upper connecting ring 105 to slide up and down on the upper connecting ring 105 and the conveying pipe 101 through the connecting rod, thereby changing the capacity between the upper and lower iris assemblies 114.
[0038] When the uppermost fan 109 moves, it drives the outer slide bar 110 above the adjusting assembly to move. This causes the outer slide bar 110 to slide on the inner slide bar 112, and through the spring 111, pushes the inner slide bar 112 to slide on the lower outer slide bar 110, compressing the spring 111 inside the lower outer slide bar 110. This changes the horizontal height of the fan 109 on the inner slide bar 112, adjusting the spacing between the multiple fans 109. The distance between the lowermost fan 109 and the fan 109 on the lower outer slide bar 110 of the adjusting assembly remains constant. As the foaming particle conveying capacity changes, the horizontal heights of the middle and uppermost fans 109 also change, thus fully driving the foaming particles within the conveying pipe 101.
[0039] like Figure 5 and Figure 6 As shown, the outer control ring 103 is fixedly connected to the external threaded rod 107, the inner control ring 104 and the inner control rod 106 are fixedly connected, the iris assembly 114 on the inner control ring 104 is rotatably connected to the inner control ring 104, the inner control ring 104 is rotatably connected to the outer control ring 103, and the outer control ring 103 is rotatably connected to the outer connecting ring 108.
[0040] Specifically, the rotation of the external threaded rod 107 is controlled by the outer control ring 103, which in turn controls the movement of the fan 109 and the upper iris assembly 114, thereby changing the capacity. The rotation of the inner control rod 106 is controlled by the inner control ring 104, which in turn controls the opening and closing of the upper iris assembly 114, thereby feeding the foamed particles. The opening and closing of the port of the inner control ring 104 is controlled by the iris assembly 114, thereby controlling the discharge of the foamed particles.
[0041] like Figure 2 , Figure 6 and Figure 9 As shown, a guide disk 116 for guiding the movement of logistics is fixedly installed on the iris component 114.
[0042] Specifically, the guide plate 116 is provided with a conical slope, which guides the foam particles and prevents the foam particles from accumulating on the side of the outlet of the iris component 114 for a long time.
[0043] like Figures 5 to 7 As shown, an iris assembly 114 is provided on the inner control ring 104, and a control lever is provided on the iris assembly 114. A groove for rotating the lever is provided on the lower connecting ring 113.
[0044] Specifically, the iris assembly 114 on the inner control ring 104 is opened and closed by a lever, thereby controlling the discharge of foam particles.
[0045] like Figure 2 , Figure 8 and Figure 9 As shown, an iris assembly 114 is slidably disposed on the upper connecting ring 105, and a crossbar 115 for controlling opening and closing is fixedly installed on the iris assembly 114.
[0046] Specifically, the iris component 114 on the upper connecting ring 105 is fixedly connected to the inner control rod 106 via the crossbar 115. The rotation of the inner control rod 106 drives the crossbar 115 to rotate, thereby controlling the opening and closing of the iris component 114 and controlling the foamed particles in the front-end conveying pipe to enter the conveying pipe 101 for quantitative control.
[0047] like Figure 2 , Figure 5 and Figure 6 As shown, a switching ring 117 is slidably disposed on the outer control ring 103. Multiple convex shafts are disposed on the switching ring 117. The convex shafts pass through the grooves of the outer control ring 103. The outer connecting ring 108 is provided with a groove corresponding to the convex shaft. A reset spring 118 is sleeved on the convex shaft. The reset spring 118 is fixedly connected to the outer control ring 103.
[0048] Specifically, when it is necessary to adjust the height of the fan 109 and the iris module 114, the switching ring 117 is manually slid downwards on the outer control ring 103, compressing the return spring 118. This causes the shaft on the switching ring 117 to disengage from the outer connecting ring 108. Then, the outer connecting ring 108 is fixed using a locking block. At this point, the operator can control the outer control ring 103 to rotate on the outer connecting ring 108, thereby driving the external threaded rod 107 to rotate, thus adjusting the fan 109 and the iris module 114 and regulating the volume of the foaming particles. After adjustment, the switching ring 117 is released, and the return spring 118 is used to insert the shaft on the switching ring 117 into the outer connecting ring 108. The locking block on the outer connecting ring 108 is then released. When the pre-quantified foamed granules need to be conveyed, the lever on the inner control ring 104 is rotated to open the lower port of the iris assembly 114. Then, the foamed granules fall by gravity. The outer control ring 103 is rotated, and the shaft of the switching ring 117 drives the outer connecting ring 108 to rotate. The fan 109 at the bottom drives the other fans 109 through the adjustment component. In turn, the external threaded rod 107 and the fans 109 rotate synchronously to agitate the foamed granules at each layer, accelerate the conveying of the foamed granules and avoid residue.
[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
