Description

Technical Field

[0001] This invention relates to the field of cement pole processing technology, specifically to a centrifugal feeding device for a cement pole production line. Background Technology

[0002] The centrifugal feeding device in cement pole production is a key piece of equipment in the production line. It is mainly used to evenly distribute concrete in a high-speed rotating steel mold and compact the concrete through centrifugal force. During the molding stage, the rotation speed is mainly divided into three stages: the first stage, with a mold speed of 100-150 rpm, can eliminate large air bubbles; the second stage, with a speed of 200-250 rpm, can refine the pores; and the third stage, with a speed of 300-400 rpm, can form a dense structure. Finally, the cement pole is cured by drying or steaming.

[0003] While existing fabric-laying devices can remove some air bubbles by changing the rotation speed, the effect of removing air bubbles is not ideal. It often requires increasing the centrifugal rotation time, which increases the production cycle of cement poles and affects production quality and efficiency.

[0004] Therefore, we propose a centrifugal feeding device for cement pole production lines. Summary of the Invention

[0005] The purpose of this invention is to provide a centrifugal feeding device for a cement pole production line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a centrifugal feeding device for a cement pole production line, comprising a base, wherein a mold for processing cement poles is provided on the upper outer surface of the base, and a driving device is provided between the two.

[0007] An ultrasonic component, comprising an ultrasonic transmitter head disposed on one outer surface of a mold and aligned with the mold via a crossbar, the crossbar being fixedly connected to a base, the ultrasonic transmitter head being fixedly connected to the crossbar, and a guide tube for spraying coupling agent being provided at the contact position between the ultrasonic transmitter head and the mold;

[0008] The drive assembly, located at the end of the mold, utilizes the rotation of the mold to force the coupling agent to flow towards the probe, making full use of the kinetic energy of the mold rotation and improving the efficiency of coupling agent delivery.

[0009] The crossbar has an infusion tube fixedly connected to its outer surface. The length of the infusion tube is the same as the length of the mold. The guide tube is fixedly connected to the annular outer surface of the infusion tube and is aligned with each group of ultrasonic transmitters, pointing to the connection between the ultrasonic transmitter and the mold. The number of ultrasonic transmitters is the same as the number of guide tubes, which is several groups.

[0010] The crossbar is fixedly connected to a fluid exchanger, which is a cylindrical shell. A piston plate is slidably connected to the inner surface of the fluid exchanger, and a piston rod is fixedly connected to the flat surface of the piston plate. A circulation pipe and a delivery pipe are fixedly connected to the annular outer surface of the fluid exchanger. The circulation pipe is a U-shaped structure, and its annular outer surface is fixedly connected to the infusion pipe. There are two sets of delivery pipes, which are located near the two ends of the fluid exchanger. A storage tank is fixedly connected to the end of the delivery pipe away from the fluid exchanger.

[0011] The two ends of the circulation pipe are located at the two ends of the fluid exchanger, and a one-way valve is fixedly connected inside each end of the circulation pipe. A one-way valve is fixedly connected inside the delivery pipe.

[0012] Specifically, the first check valve allows the liquid to flow from the exchange fluid to the circulation pipe, and the second check valve allows the liquid to flow from the storage tank to the exchange fluid.

[0013] The drive assembly includes a drive disk one and a drive disk two. The outer surface of the drive disk one is provided with a support frame, and the two are rotatably connected. The drive disk one and the drive disk two are fixedly connected by a through rod. The through rod is fixed at a non-central area of ​​the drive disk one and the drive disk two. The annular outer surface of the through rod is rotatably connected to a connecting rod through a bearing. The other end of the connecting rod is rotatably connected to a piston rod. The drive disk two is connected to the mold.

[0014] The mold is divided into an upper mold and a lower mold, which are fixedly connected by bolts. A connecting plate is embedded between them. A movable friction plate is provided at the end of the connecting plate away from the mold. A guide rod is fixedly connected to the center of the friction plate. A guide groove is opened at the corresponding position of the connecting plate and the guide rod, and the guide rod is located inside the guide groove. A spring is fixedly connected between the connecting plate and the friction plate.

[0015] The outer surface of the connecting plate is provided with a sliding groove, and the friction plate is provided with a sliding groove at the corresponding position of the sliding groove. A sliding plate is slidably connected inside the sliding groove. A slider matching the sliding groove is fixedly connected to the end of the sliding plate. A counterweight plate is fixedly connected to the end of the sliding plate away from the slider. A reserved groove is provided at the corresponding position of the friction plate and the counterweight plate. The sliding groove is designed with an M-shaped structure.

[0016] The sliding groove has a T-shaped constraint block fixedly connected inside, and the sliding plate has a constraint groove on its surface into which the constraint block is embedded.

[0017] The slider is designed as a plate and has a certain degree of elasticity.

[0018] This invention has at least the following beneficial effects:

[0019] By using ultrasonic components and low-frequency ultrasound to eliminate air bubbles in cement, the quality of cement rods can be improved while increasing production efficiency. Using a coupling agent as an intermediate medium in conjunction with the ultrasonic transmitter head can achieve the effect of eliminating air bubbles with ultrasound while reducing the number of ultrasonic transmitter heads. At the same time, it can ensure the versatility of the mold and eliminate the need for excessive modification of the mold.

[0020] By setting the drive component, it can be matched with the rotation speed of the mold. When the mold is in the low-speed stage, the cement slurry is in a plastic state and air bubbles can migrate freely. By utilizing the ultrasonic cavitation effect, the slurry can be uniformly penetrated and the air bubbles can be eliminated. When the mold is in the high-speed stage, the centrifugal force makes the cement slurry layered and dense. At this time, the drive component will disconnect from the mold to avoid the continuous action of sound waves causing cement segregation and stratification. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-10 The present invention provides a technical solution: a centrifugal feeding device for a cement pole production line, including a base 1, wherein a mold 2 for processing cement poles is provided on the upper outer surface of the base 1, and a driving device is provided between the two (mainly composed of a motor and a gearbox, which are existing technologies and will not be described in detail here).

[0034] The ultrasonic component 3 includes an ultrasonic transmitter 30, which emits ultrasonic waves of 20-100kHz to eliminate air bubbles inside the cement through cavitation. The ultrasonic transmitter 30 is disposed on one outer surface of the mold 2 and is aligned with the mold 2 by a crossbar 11. The crossbar 11 is fixedly connected to the base 1, and the ultrasonic transmitter 30 is fixedly connected to the crossbar 11. A guide pipe 31 for spraying coupling agent is provided at the contact position between the ultrasonic transmitter 30 and the mold 2 to reduce the loss of sound wave energy transmission by spraying coupling agent.

[0035] The drive assembly 5 is located at the end of the mold 2. By utilizing the rotation of the mold 2, the torque amplification effect of the motor and gearbox cooperation is fully utilized at low speed, forcing the coupling agent to flow to the ultrasonic transmitter head 30. This fully utilizes the kinetic energy of the rotation of the mold 2 and improves the efficiency of coupling agent delivery.

[0036] Please see Figure 2 , 3An infusion tube 32 is fixedly connected to the outer surface of the crossbar 11. The length of the infusion tube 32 is the same as the length of the mold 2. The guide tube 31 is fixedly connected to the annular outer surface of the infusion tube 32 and is aligned with each group of ultrasonic transmitters 30 and points to the connection between the ultrasonic transmitters 30 and the mold 2. The number of ultrasonic transmitters 30 is the same as that of the guide tubes 31, which is several groups. This can effectively ensure the penetration efficiency of ultrasound and eliminate bubbles more evenly.

[0037] Please see Figure 4 , 5 The end of the crossbar 11 is fixedly connected to a fluid exchanger 34, which is a cylindrical shell design. A piston plate 35 is slidably connected to the inner surface of the fluid exchanger 34, and a piston rod 36 is fixedly connected to the flat surface of the piston plate 35. A circulation pipe 33 and a delivery pipe 39 are fixedly connected to the annular outer surface of the fluid exchanger 34. The circulation pipe 33 is a U-shaped structure design, and its annular outer surface is fixedly connected to the infusion pipe 32. There are two sets of delivery pipes 39, which are located near the two ends of the fluid exchanger 34. A storage tank is fixedly connected to the end of the delivery pipe 39 away from the fluid exchanger 34. The piston plate 35 and the piston rod 36 slide along the slidable direction to press out the coupling agent inside the fluid exchanger 34. The U-shaped circulation pipe 33 cooperates with the one-way valve 38 and the two-way valve 40 to reduce the gap in liquid transmission and make the transmission of coupling agent smoother.

[0038] Please see Figure 5 The two ends of the circulation pipe 33 are respectively located at the two ends of the fluid exchanger 34. One-way valve 38 is fixedly connected inside both ends of the circulation pipe 33. One-way valve 40 is fixedly connected inside the delivery pipe 39. One-way valve 38 allows the liquid to flow from the fluid exchanger 34 to the circulation pipe 33. One-way valve 40 allows the liquid to flow from the storage tank to the fluid exchanger 34. Through the design of the above structure, when the piston plate 35 moves, coupling agent always enters the delivery pipe 32 and the fluid exchanger 34, thereby improving the delivery efficiency of the coupling agent.

[0039] Please see Figure 4 , 5The drive assembly 5 includes a drive disk 1 50 and a drive disk 2 51. The outer surface of the drive disk 1 50 is provided with a support frame 10, and the two are rotatably connected. The drive disk 1 50 and the drive disk 2 51 are fixedly connected by a through rod 52. The through rod 52 is fixed at a non-central area of ​​the drive disk 1 50 and the drive disk 2 51. The annular outer surface of the through rod 52 is rotatably connected to a connecting rod 37 via a bearing. The other end of the connecting rod 37 is rotatably connected to a piston rod 36. The drive disk 2 51 is connected to the mold 2. When the mold 2 rotates, it will drive the drive disk 1 50 and the drive disk 2 51 to rotate, thereby effectively pushing the coupling agent to be sprayed onto the surface of the mold 2. The drive disk 1 50, the drive disk 2 51, and the through rod 52 are fixedly connected and have a U-shaped cross-section, which is conducive to the rapid rotation of the connecting rod 37.

[0040] Please see Figure 10 The mold 2 is divided into an upper mold 20 and a lower mold 21, which are fixedly connected by bolts. A connecting plate 53 is embedded between them. Corresponding grooves can be opened on the surface of the connecting plate 53 to make the connection more stable. A movable friction plate 64 is provided at the end of the connecting plate 53 away from the mold 2. The contact surfaces of the friction plate 64 and the driving plate 51 are both provided with a composite friction coating to ensure that sufficient friction can be provided when in contact. A guide rod 61 is fixedly connected to the center of the friction plate 64. A guide groove 62 is opened at the corresponding position of the connecting plate 53 and the guide rod 61, and the guide rod 61 is located inside the guide groove 62. A spring is fixedly connected between the connecting plate 53 and the friction plate 64 to enhance the stability of the friction plate 64 when sliding.

[0041] Please see Figure 7-9The outer surface of the connecting plate 53 is provided with a sliding groove 54. The friction plate 64 is provided with a sliding groove 60 at a position corresponding to the sliding groove 54. A sliding plate 55 is slidably connected inside the sliding groove 60. A slider 59 matching the sliding groove 54 is fixedly connected to the end of the sliding plate 55. A counterweight plate 56 is fixedly connected to the end of the sliding plate 55 away from the slider 59. A reserved groove 63 is provided at a position corresponding to the counterweight plate 56 on the friction plate 64. The sliding groove 54 is designed with an M-shaped structure. When the mold 2 is in the starting stage, the connecting plate 53 will drive the friction plate 64 to rotate synchronously. At this time, the friction plate 64 is not in contact with the driving plate 51. As the rotation speed of the mold 2 increases, but the overall rotation speed is still in a low speed range, the centrifugal force on the counterweight plate 56 gradually increases. At this time, the counterweight plate 56 will pull the sliding plate 55 to drive the slider 59. Sliding along the sliding groove 60, the slider 59 moves along the sliding groove 54, thereby pushing the friction disk 64 towards the drive disk 51 until they are fully engaged. At this time, the friction disk 64 drives the drive assembly 5 to rotate and complete the power transmission. At low speeds, the drive assembly 5 is activated in conjunction with the ultrasonic transmitter 30 to effectively eliminate air bubbles. As the rotation speed of the mold 2 continues to increase, the counterweight plate 56 continues to pull the sliding plate 55 along the sliding groove 60. The M-shaped sliding groove 54 loses its obstruction of the slider 59. At this time, under the traction of the spring, the friction disk 64 disengages from the drive disk 51 and disconnects. The ultrasonic transmitter 30 loses the coupling agent as a conductive medium and cannot act on the cement interior, preventing the time effect of the sound wavelength from causing segregation and stratification of the concrete. As the rotation speed of the mold 2 increases, the ultrasonic transmitter 30 can be turned off to achieve energy saving.

[0042] Please see Figure 8 The sliding groove 60 is fixedly connected to a T-shaped constraint block 58, and the sliding plate 55 has a constraint groove 57 embedded in the constraint block 58 on its surface, which restricts the movement direction of the sliding plate 55 and increases the stability of the overall structure.

[0043] Please see Figure 8 The slider 59 has a plate-like structure and a certain degree of elasticity. When subjected to centrifugal force, the slider 59 contacts the groove 54 to form an interference fit, which increases the stability of the structure. At the same time, when the mold 2 decelerates, the centrifugal force on the counterweight plate 56 gradually decreases, which can prevent the slider 59 from resetting and prevent the drive disk from reconnecting. When the slider 59 needs to be reset, it can be manually reset.
