Description

Technical Field

[0002] This invention relates to the field of material conveying technology, and more specifically, to a continuous material conveying mechanism for fire door filling equipment. Background Technology

[0004] Fire doors can prevent the spread of fire for a certain period of time and ensure the evacuation of personnel. In order to ensure the fire resistance performance of fire doors, it is necessary to use grouting equipment to fill the installation gaps between the fire doors and the building, thereby improving the reliability and tightness of the installation between the fire doors and the building. In actual construction, in order to improve construction efficiency, cement mortar is mixed on the construction site. During this process, it is often necessary to use a conveying mechanism to introduce the mortar into the mixing box of the equipment to prepare the fireproof materials.

[0005] Intelligent suspended feeding mechanisms generally consist of a suspended track, a conveyor chain, and a suspended hopper. The chain, driven by a motor and transmission device, circulates on the track. The hopper, suspended on the chain, moves with the chain, continuously transporting mortar to the workstation above the fire door filling equipment to complete the material conveying. However, traditional clamping mechanisms use clamping mechanisms to fix the material frame and drive it to flip (such as spring or pneumatic clamping). When the material frame is fully loaded with mortar and moves to the corresponding position of the filling equipment, it is guided by flipping downwards. The mortar directly impacts the receiving filling equipment, and the instantaneous impact force can easily cause deformation of the relevant structure and parts of the filling equipment, affecting subsequent use. It can also cause mortar to splash, resulting in material loss and pollution of the operating environment. Summary of the Invention

[0007] This invention provides a continuous material guiding mechanism for fire door filling equipment, which solves the technical problem in related technologies where mortar directly impacts the receiving filling equipment when the material frame flips downward to guide the material. The instantaneous impact force can easily cause deformation of the relevant structure and parts of the filling equipment, affecting subsequent use, and also causing mortar to splash, resulting in certain material loss and pollution of the operating environment.

[0008] This invention provides a continuous feeding mechanism for a fire door filling equipment, comprising:

[0009] The suspended track, conveyor chain, double sets of rollers, clamping and turning mechanism, material frame and guide track, together with the intelligent suspended conveyor, guide the mortar material to the working area of ​​the fire door filling equipment;

[0010] The conveying and guiding module includes a connecting vertical plate and a pair of semi-arc grooves. The semi-arc grooves on both sides are symmetrically installed on the outer wall of the connecting vertical plate. A U-shaped plate is rotatably connected to the lower center of the connecting vertical plate. Sleeves are fixedly connected to the middle of both sides of the material frame. The sleeves on both sides are slidably connected to the inner wall of the semi-arc grooves on both sides. A docking tooth plate is slidably connected to the lower sides of both sides of the connecting vertical plate. The unloading action of the material frame is flipped downward by the clamping and flipping mechanism. The movement trajectory of the sleeves on both sides is coordinated with the docking tooth plate on both sides to form a docking. The docking tooth plate is pushed close to the suspension track, so that the U-shaped plate changes from the original horizontal state to the downward tilted state, which assists in the guiding and conveying of mortar material.

The hollow cylinders and piston rods on both sides are rotatably connected to the middle of the connecting vertical plate and the U-shaped plate, respectively. The outer wall of the piston rod is slidably connected to the inner wall of the hollow cylinder. While the U-shaped plate guides and conveys the mortar material to achieve buffer protection, it also forms a suction action for lubricating oil. The output spray is located at the position where the double set of rollers contact the suspension track, ensuring the continuous and smooth conveying process.

[0014] As a further optimization of the present invention, a pair of guide rods are fixedly connected to both sides of the inner wall of the connecting plate, and the mating tooth plates on both sides are slidably connected to the outer walls of the guide rods on both sides.

[0015] As a further optimization of the present invention, a compensation spring is sleeved on the outer wall of the guide rods on both sides. One end of the compensation spring is fixedly connected to the connecting vertical plate, and the other end of the compensation spring is fixedly connected to the mating tooth plate.

[0016] As a further optimization of the present invention, the bottom of the transmission gears on both sides are fixedly connected with irregularly shaped levers, and the lower left and right sides of the connecting plate are fixedly connected with sleeves, and the inner wall of the sleeves is slidably connected with convex cylinders.

[0017] As a further optimization of the present invention, the inner walls of the convex cylinder are fixedly connected to both sides of the connecting blocks, the irregular-shaped lever passes through the sleeve and extends into the interior of the convex cylinder, and the bottom outer wall of the irregular-shaped lever is slidably connected to the outer walls of the connecting blocks on both sides.

[0018] As a further optimization of the present invention, a connecting spring is sleeved on the outer wall of the irregularly shaped lever, and the two ends of the connecting spring are fixedly connected to the sleeve and the convex cylinder respectively. The bottom ends of the convex cylinders on both sides are fixedly connected to the top of the U-shaped plate.

[0019] As a further optimization of the present invention, the cyclic maintenance module further includes:

[0020] An injection tee is fixedly installed at the bottom of the two hollow cylinders. A conveying tee is fixedly connected to the top of the two hollow cylinders. Output tee pipes are symmetrically arranged on both sides of the outer wall of the double rollers. The end of the injection tee pipe away from the two hollow cylinders passes through and extends into the interior of the output tee pipe.

[0021] As a further optimization of the present invention, multiple atomizing nozzles are fixedly installed on both sides of the top of the output three-way pipe from left to right in the horizontal direction, and the output direction of the atomizing nozzles is directly facing the outer walls of the two sets of rollers.

[0022] As a further optimization of the present invention, the conveying chain is rotatably connected to the outer wall of the suspension track, the double set of rollers is fixedly connected to the conveying chain and rotates along the trajectory of the suspension track, the clamping and flipping mechanism is fixedly connected to the bottom of the double set of rollers, the material frame is clamped and disposed in the middle of the clamping and flipping mechanism, the guide track is fixedly connected to the lower part of the outer wall of the suspension track, and a ball bearing is fixedly connected to the lower middle part of the inner wall of the connecting plate, and the ball bearing is slidably connected to the inner wall of the guide track.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The continuous material guiding mechanism for a fire door filling device described in this invention uses a clamping and flipping mechanism to fix and transport the material frame to the fire door filling device and flip it downwards to pour out the mortar. Compared with the prior art, the rotating trajectory of the material frame is firstly guided and limited by a semi-arc groove, which improves the stability and accuracy of the material frame during the flipping process and avoids deviation or shaking during rotation. After the material frame rotates downwards by 180 degrees, the centrifugal impact of the rotation is converted into a horizontal displacement change, and the original centrifugal force is converted into a rotational force in the perpendicular direction. This further drives the top of one end of the U-shaped plate to be lifted to a certain height and tilted, so that while the material frame is rotating and guiding the material, the U-shaped plate can be adjusted to the position in a downward tilted state to connect with the filling device, forming a connection path between the material frame and the filling device, and assisting in the uniform and continuous delivery of mortar into the filling device.

[0025] 2. The continuous material guiding mechanism for fire door filling equipment described in this invention, corresponding to the above-mentioned upward flipping and resetting of the material frame, converts the original lifting force applied to the U-shaped plate into a downward pushing force, so that the U-shaped plate returns to its original horizontal state. During the subsequent suspension and conveying of mortar, it forms a support at the bottom, and recovers the mortar that is offset and swayed by centrifugal force during the suspension and conveying process, especially during the arc rotation stage, thus avoiding dripping into the working environment and causing pollution, and reducing the waste of mortar raw materials. The U-shaped plate, in conjunction with the flipping action of the material frame, realizes the switching between horizontal and inclined states, completes the conversion of raw material recovery and connecting material guiding functions, and further improves the efficiency of filling material conveying.

[0026] 3. The continuous material guiding mechanism for fire door filling equipment described in this invention, in conjunction with the state switching of the U-shaped plate, assists in the continuous guiding and conveying of mortar. The material frame rotates and is conveyed on the suspended track. When the U-shaped plate returns to the horizontal state in the previous stage, the upward movement of its bottom provides an upward pulling force for the piston rod, further drawing the lubricating oil into the interior of the hollow cylinder for temporary storage. In the next stage, during the downward tilting of the U-shaped plate to guide the material, a pushing force is generated on the piston rod, pushing the lubricating oil to the double set of rollers for output. As the double set of rollers move, the lubricating oil is evenly covered on the outer wall of the suspended guide rail, forming a low-resistance conveying path for the movement of the material frame.

[0027] 4. The continuous material guiding mechanism for fire door filling equipment described in this invention achieves the switching between horizontal and inclined states through the flipping action of the U-shaped plate and the material frame, completing the conversion of raw material recycling and material guiding functions. At the same time, while triggering the extraction of lubricating oil to maintain the conveying path of the material frame, the piston rod and the hollow cylinder sleeve cooperate with the bottom of the U-shaped plate to provide support, further buffering and protecting the U-shaped plate conveying mortar material, reducing vibration interference caused by impact during material guiding.

[0051] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0052] like Figures 1 to 14 As shown in the embodiment of the present invention, a continuous material guiding mechanism for a fire door filling equipment includes:

[0053] The suspended track 1, conveyor chain 2, double rollers 3, clamping and turning mechanism 4, material frame 5, and guide track 6, together with the intelligent suspended conveyor, guide and transport the mortar material to the working area of ​​the fire door filling equipment.

[0054] The conveying and guiding module 7 includes a connecting vertical plate 701 and a pair of semi-arc grooves 702. The two semi-arc grooves 702 are symmetrically installed on both sides of the outer wall of the connecting vertical plate 701. A U-shaped plate 713 is rotatably connected to the lower center of the connecting vertical plate 701. A sleeve 703 is fixedly connected to the middle of both sides of the material frame 5. The sleeve 703 is T-shaped. The two sleeves 703 are slidably connected to the inner wall of the two semi-arc grooves 702. A docking tooth plate 704 is slidably connected to the lower sides of the connecting vertical plate 701. After the sleeve 703 rotates downward into place, it is on the same straight line as the docking tooth plate 704. The material frame 5 is unloaded by the downward flipping action of the clamping and flipping mechanism 4. The movement trajectory of the two sleeves 703 and the docking tooth plate 704 on both sides form a docking. The docking tooth plate 704 is pushed close to the suspension rail 1, so that the U-shaped plate 713 changes from the original horizontal state to the downward tilting state, which assists in the guiding and conveying of mortar material.

[0055] The circulating maintenance module 8 includes a pair of hollow cylinders 801 and piston rods 802. The hollow cylinders 801 and piston rods 802 on both sides are rotatably connected to the middle of the connecting vertical plate 701 and the U-shaped plate 713, respectively. The outer wall of the piston rod 802 is slidably connected to the inner wall of the hollow cylinder 801. While the U-shaped plate 713 guides and conveys the mortar material, it achieves buffer protection and forms a suction action for lubricating oil. The output spray is at the position where the double set of rollers 3 contacts the suspension track 1, ensuring the continuous and smooth conveying process.

[0056] The conveyor chain 2 is rotatably connected to the outer wall of the suspension track 1. The double set of rollers 3 are fixedly connected to the conveyor chain 2 and rotate along the trajectory of the suspension track 1. The clamping and flipping mechanism 4 is fixedly connected to the bottom of the double set of rollers 3. The material frame 5 is clamped and set in the middle of the clamping and flipping mechanism 4. The clamping and flipping mechanism 4 plays a role in fixing and flipping adjustment of the material frame 5. The guide track 6 is fixedly connected to the lower outer wall of the suspension track 1. The ball bearing 9 is fixedly connected to the lower middle part of the inner wall of the connecting vertical plate 701. The ball bearing 9 is slidably connected to the inner wall of the guide track 6.

[0057] It should be noted that the material frame 5 rotates and moves around the outer wall of the suspension track 1 as the conveyor chain 2 rotates, and stops at the position corresponding to the fire door filling equipment. The material frame 5 is adjusted to rotate downward by 180 degrees by the clamping and flipping mechanism 4 to guide and transport the mortar material. During the flipping process, the material frame 5 rotates along the inner wall of the two semi-arc grooves 702 through the two side sleeves 703, and slides from the original upper position to the lower symmetrical position.

[0058] like Figure 7 - Figure 12 As shown, the conveying and guiding module 7 also includes:

[0059] A pair of transmission gears 705 are rotatably connected to the middle of the two sides of the connecting plate 701. The two transmission gears 705 are meshed with the two mating tooth plates 704. A pair of guide rods 706 are fixedly connected to both sides of the inner wall of the connecting plate 701. The two guide rods 706 are symmetrically arranged with respect to the center of the mating tooth plate 704. The two mating tooth plates 704 are slidably connected to the outer wall of the two guide rods 706. A compensating spring 707 is sleeved on the outer wall of the two guide rods 706. One end of the compensating spring 707 is fixedly connected to the connecting plate 701, and the other end of the compensating spring 707 is fixedly connected to the mating tooth plate 704.

[0060] It should be noted that the material frame 5 generates a certain impact force during the downward flipping process, and the sleeves 703 on both sides contact the mating teeth 704 on both sides in the rotation path, transmitting the impact force to the mating teeth 704 so that it slides along the outer wall of the guide rods 706 on both sides in the horizontal direction and generates a certain displacement. The compensation spring 707 provides a certain buffer support and protection for its movement process. During the movement, the mating teeth 704 contacts the meshing transmission gear 705 and causes it to rotate.

[0061] Both sides of the transmission gear 705 are fixedly connected to the bottom of the irregularly shaped lever 708. The irregularly shaped lever 708 is composed of a rod body and two symmetrically arranged arc-shaped fins. Both sides of the connecting plate 701 are fixedly connected to the lower left and right sides of the sleeve 709. The inner wall of the sleeve 709 is slidably connected to the convex cylinder 710. Both sides of the inner wall of the convex cylinder 710 are fixedly connected to the docking block 711. The irregularly shaped lever 708 passes through the sleeve 709 and extends into the interior of the convex cylinder 710. The outer wall of the bottom end of the irregularly shaped lever 708 is slidably connected to the outer wall of the docking block 711 on both sides. The outer wall of the irregularly shaped lever 708 is fitted with a connecting spring 712. The two ends of the connecting spring 712 are fixedly connected to the sleeve 709 and the convex cylinder 710 respectively. The bottom ends of both sides of the convex cylinder 710 are fixedly connected to the top of the U-shaped plate 713.

[0062] It should be noted that as the transmission gear 705 rotates, it further drives the irregularly shaped lever 708 to rotate inside the sleeve 709. During the rotation, the arc-shaped fins on both sides of the irregularly shaped lever 708 come into contact with the docking blocks 711 on both sides. Under the cooperation of the arc surface of the arc-shaped fins, the convex cylinder 710 moves upward along the inner wall of the sleeve 709, generating a squeezing force on the connecting spring 712 inside the sleeve 709, causing it to deform and accumulate a certain elastic potential energy. As the convex cylinder 710 moves upward, it can drive one end of the U-shaped plate 713 to move upward synchronously, thereby changing the U-shaped plate 713 from its original horizontal state to a downward tilting state. This changes the original function of the U-shaped plate 713 from hanging and conveying the spilled slurry to docking and guiding the material, forming a connection path between the material frame 5 and the filling equipment, and assisting in the uniform and continuous delivery of mortar to the inside of the filling equipment.

[0063] Correspondingly, after the mortar material in the material frame 5 is transported to this stage, the clamping and flipping mechanism 4 flips the material frame 5 upward to adjust and reset it. The force applied by the sleeves 703 on the docking tooth plate 704 disappears. Under the action of the elastic potential energy generated by the compression of the compensating springs 707 on both sides, the docking tooth plate 704 moves in the opposite direction to return to its original position. During this process, the transmission gear 705 is subjected to a reverse rotational force, which causes the irregular lever 708 to rotate in the opposite direction. With the elastic potential energy accumulated by the connecting spring 712, the convex cylinder 710 slides out from the inner wall of the sleeve 709, generating a downward pushing force on the U-shaped plate 713. This causes the U-shaped plate 713 to return from a downward tilted state to its original horizontal state, thus serving as a support for the subsequent transport of mortar material in the material frame 5 and preventing the mortar from dripping into the filling environment of the fire door.

[0064] like Figure 6 - Figure 7 , Figure 9 and Figure 14 As shown, the cyclic maintenance module 8 also includes:

[0065] An injection tee 803 is fixedly installed at the bottom of the two hollow cylinders 801. The end of the injection tee 803 away from the two hollow cylinders 801 can be flexibly connected to the inside of the lubricating oil storage container (not shown in the figure). A delivery tee 804 is fixedly connected to the top of the two hollow cylinders 801. Output tee 805s are symmetrically arranged on both sides of the outer wall of the double rollers 3. The end of the injection tee 803 away from the two hollow cylinders 801 extends through and into the inside of the output tee 805. Multiple atomizing nozzles 806 are fixedly installed horizontally from left to right on both sides of the top of the output tee 805. The output direction of the atomizing nozzles 806 is directly facing the two sides of the outer wall of the double rollers 3.

[0066] It should be noted that, in conjunction with the state switching of the U-shaped plate 713, the mortar material is continuously guided and conveyed. The material frame 5 rotates and is conveyed on the suspension track 1. When the U-shaped plate 713 is reset to the horizontal state in the previous stage, the upward movement of its bottom provides an upward pulling force for the piston rod 802, which draws the lubricating oil into the hollow cylinder 801 through the injection three-way pipe 803 for temporary storage. In the next stage, when the U-shaped plate 713 tilts downward to guide the material, it generates a pushing force on the piston rod 802. The lubricating oil is pushed to the double rollers 3 through the conveying three-way pipe 804 and finally output by the atomizing nozzles 806 set in the middle of the output three-way pipe 805. As the double rollers 3 move, the lubricating oil is evenly covered on the outer wall of the suspension track 1, forming a low-resistance conveying path for the movement of the material frame 5.

[0067] Furthermore, during the switching between horizontal and inclined states achieved by the flipping action of the U-shaped plate 713 in conjunction with the material frame 5, and the conversion of raw material recycling and material guiding functions, while triggering the extraction of lubricating oil to maintain the conveying path of the material frame 5, the piston rod 802 and the hollow cylinder 801 are sleeved together to support the bottom of the U-shaped plate 713, which further buffers and protects the U-shaped plate 713 conveying mortar material, reducing vibration interference caused by impact during material guiding.

[0068] Working principle: First, the mortar used for filling the fire door is injected into the inside of the material frame 5 by the relevant preparation device. Then, the material frame 5 moves around the outer wall of the suspension track 1 with the rotation of the conveyor chain 2 and stops at the position corresponding to the placement of the fire door filling equipment (this is the existing technology of intelligent suspension conveyor, which will not be described in detail here). The material frame 5 is adjusted to rotate downward by 180 degrees by the clamping and flipping mechanism 4 to guide and transport the mortar. During the flipping process, the material frame 5 rotates along the inner wall of the two semi-arc grooves 702 through the sleeves 703 on both sides, and slides from the original upper position to the lower symmetrical position.

[0069] During the downward flipping process, the material frame 5 generates a certain impact force. In the rotation path, the sleeves 703 on both sides contact the mating teeth 704 on both sides, transmitting the impact force to the mating teeth 704. This causes the teeth 704 to slide horizontally along the outer wall of the guide rods 706 on both sides, generating a certain displacement. The compensating springs 707 provide buffering and support protection during this movement. During the movement, the mating teeth 704 contact the meshing transmission gears 705, causing them to rotate. This further drives the shaped lever 708 to rotate inside the sleeve 709. During rotation, the arc-shaped fins on both sides of the shaped lever 708 contact the mating blocks 71 on both sides. 1. When contact occurs, the arc surface of the arc-shaped fins drives the convex cylinder 710 to move upward along the inner wall of the sleeve 709, generating a squeezing force on the connecting spring 712 inside the sleeve 709, causing it to deform and accumulate a certain elastic potential energy. As the convex cylinder 710 moves upward, it can drive one end of the U-shaped plate 713 to move upward synchronously, thereby changing the U-shaped plate 713 from its original horizontal state to a downward tilted state. This changes the original function of the U-shaped plate 713 from hanging and conveying the spilled slurry to the function of docking and guiding the material, forming a connection path between the material frame 5 and the grouting equipment, and assisting in the uniform and continuous delivery of mortar to the inside of the grouting equipment.

[0070] Correspondingly, after the mortar material in the material frame 5 is transported to this stage, the clamping and flipping mechanism 4 flips the material frame 5 upward to adjust and reset it. The force applied by the sleeves 703 on the docking tooth plate 704 disappears. Under the action of the elastic potential energy generated by the compression of the compensating springs 707 on both sides, the docking tooth plate 704 moves in the opposite direction to return to its original position. During this process, the transmission gear 705 is subjected to a reverse rotational force, which causes the irregular lever 708 to rotate in the opposite direction. With the elastic potential energy accumulated by the connecting spring 712, the convex cylinder 710 slides out from the inner wall of the sleeve 709, generating a downward pushing force on the U-shaped plate 713. This causes the U-shaped plate 713 to return from the downward tilted state to the original horizontal state, which serves as a support for the subsequent transport of mortar material in the material frame 5 and prevents the mortar from dripping into the filling environment of the fire door.

[0071] In conjunction with the state switching of the U-shaped plate 713, the mortar material is continuously guided and conveyed. The material frame 5 rotates and is conveyed on the suspension track 1. When the U-shaped plate 713 is reset to the horizontal state in the previous stage, the upward movement of its bottom provides an upward pulling force for the piston rod 802, which draws the lubricating oil into the hollow cylinder 801 through the injection three-way pipe 803 for temporary storage. In the next stage, when the U-shaped plate 713 tilts downward to guide the material, it generates a pushing force on the piston rod 802. The lubricating oil is pushed to the double set of rollers 3 through the conveying three-way pipe 804 and finally output by the atomizing nozzles 806 set in the middle of the output three-way pipe 805. As the double set of rollers 3 moves, the lubricating oil is evenly covered on the outer wall of the suspension track 1, forming a low-resistance conveying path for the movement of the material frame 5.

[0072] Furthermore, during the switching between horizontal and inclined states achieved by the U-shaped plate 713 in conjunction with the flipping action of the material frame 5, and the conversion of raw material recycling and material guiding functions, while triggering the extraction of lubricating oil to maintain the conveying path of the material frame 5, the piston rod 802 and the hollow cylinder 801 are sleeved together to support the bottom of the U-shaped plate 713, which further buffers and protects the U-shaped plate 713 conveying mortar material, reduces the vibration interference caused by the impact force during the material guiding process, and ensures the continuous stability of the mortar material guiding and conveying process.

[0073] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
