Description

Technical Field

[0001] The invention belongs to the technical field of liquid flow battery electrolyte container molding equipment, and in particular relates to a double-axis rotating frame structure for liquid flow battery electrolyte container molding. Background Art

[0002] Liquid flow energy storage battery is a new type of electrochemical long-term energy storage technology, which is mainly composed of three parts: battery stack system, electrolyte storage system and electronic control system. It has the advantages of high safety, large capacity, long life, environmental friendliness, fast response speed and freedom of site selection.

[0003] Liquid flow energy storage batteries require a dedicated large-capacity storage container for liquid flow battery electrolyte, which is compatible with the liquid flow battery electrolyte storage system. Large-capacity storage containers require molding machines for production and preparation. Conventional medium and large-sized dual-axis molding machines have limited finished product sizes, so the molds are relatively light and adopt a single fulcrum + counterweight structure. This structural design cannot bear the weight of large molds and the impact vibration caused by the flow of materials in the mold during rotation, and occupies a large space. In conventional molding machines, the connection between the mold and the molding machine is fixed to the mold spider web frame with a simple U-shaped screw clip. The spider web frame of the rotary molding machine cannot meet the problem of bearing the heavy weight of super-large workpieces. In addition, there is also the problem of effective and safe fixation of the spider web frame and the super-large workpiece. During the rotary molding heating process, the mold needs to switch the forward and reverse rotation of the secondary shaft at regular intervals, so rotary braking is required. The braking of the secondary shaft of the existing medium and large dual-axis rotary molding machine relies on the electromagnetic power-off brake of the secondary shaft power motor. However, when the weight of the workpiece is large, the electromagnetic power-off brake cannot effectively brake. In extreme cases, it will cause the secondary shaft to stall and reverse, causing chain breakage and gear breakage.

[0004] Therefore, how to provide a dual-axis rotating frame structure for forming a liquid flow battery electrolyte container suitable for the preparation of large workpieces is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides a dual-axis rotating frame structure for forming a liquid flow battery electrolyte container, which can adapt to the production and preparation of super-large molded containers, solve the problem of the molding machine bearing the heavy weight of super-large workpieces, and avoid the vibration and impact problems caused by the flow of materials in the mold during rotation. It is safe and reliable to use and meets the production and preparation needs of super-large workpieces.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: a double-axis rotating frame structure for forming an electrolyte container of a flow battery, comprising:

[0007] A mobile base, wherein both sides of the mobile base are fixed with vertical frames, and an outer frame rotating motor and an inner frame rotating motor are fixed on the vertical frame on one side;

[0008] A rotating outer frame, the rotating outer frame is located between two vertical frames, the middle parts of the two side ends of the rotating outer frame are respectively connected with a rotating shaft and a hollow shaft, the rotating shaft and the hollow shaft are respectively rotatably mounted on the vertical frames through bearings, the hollow shaft is close to a vertical frame on one side where the motor is arranged, the hollow shaft is transmission-connected with the output end of the rotating motor of the outer frame and causes the rotating outer frame to rotate; a power connection shaft is rotationally arranged on the inner side of the hollow shaft, and the power connection shaft is transmission-connected with the output end of the rotating motor of the inner frame;

[0009] A rotating inner frame, the rotating inner frame is located inside the rotating outer frame, two ends of the rotating inner frame are rotatably connected to two ends of the rotating outer frame through support shafts, the rotating direction of the rotating inner frame is perpendicular to the rotating direction of the rotating outer frame, and a plurality of fixing seats for mounting molds are provided on the rotating inner frame;

[0010] A worm gear transmission mechanism is installed on the rotating outer frame, the worm wheel in the worm gear transmission mechanism rotates synchronously with the support shaft, and the worm in the worm gear transmission mechanism is drivingly connected to the power connection shaft.

[0011] The technical effect produced by the present invention is: the movable base and the bracket provide a supporting foundation for the rotating outer frame, and are also convenient for the transportation and use of the equipment. The two upright frames provide double supporting points, which jointly bear the rotation of the rotating outer frame, so that the rotating outer frame is stable and reliable during the rotation process, and the load capacity of the rotating outer frame is improved. The rotating inner frame is rotatably connected to the inner side of the rotating outer frame, and the rotation directions of the two are perpendicular and do not interfere with each other. The mold is fixed on the rotating inner frame, and the cooperation of the rotating outer frame and the rotating inner frame realizes the continuous rotation process of the mold along two mutually perpendicular axes. After the molding material in the mold is melted, it is evenly coated and melt-adhered to the inner surface of the mold under the action of gravity and heat to form a product of desired shape. The present invention realizes the rotation and braking control of the rotating inner frame through a worm gear transmission mechanism. Based on the self-locking property of the worm gear transmission, it can be effectively controlled when the mold brakes and reverses the rotation, avoiding damage to the transmission components and improving the usability and reliability of the equipment.

[0012] Preferably, a motor seat is fixed on the stand on one side, the outer frame rotating motor and the inner frame rotating motor are arranged in upper and lower layers and fixed on the motor seat respectively, and a double-row chain transmission is adopted between the output shaft of the outer frame rotating motor and the hollow shaft.

[0013] The resulting technical effect is: in specific implementation, the motor seat is a double-layer motor seat, which can respectively fix the outer frame rotating motor and the inner frame rotating motor. Due to the load and deadweight issues of the equipment, a double-row chain drive is adopted with strong transmission capacity, thereby realizing the rotation process of the rotating outer frame.

[0014] Preferably, one end of the power connection shaft is coaxially fixedly connected to the output shaft of the inner frame rotating motor, and a sprocket is connected to the outer side wall of the other end of the power connection shaft, and a transmission chain is connected to the sprocket, and the transmission chain is connected to the worm gear transmission.

[0015] The resulting technical effect is: the power connecting shaft is used to drive the inner frame rotating motor and the worm gear transmission mechanism, the transmission chain can make up for the space limitation, and a smaller driving force can meet the driving requirements of the worm gear transmission mechanism.

[0016] Preferably, there are two groups of worm gear transmission mechanisms and they are respectively arranged on the outside of the two ends of the rotating outer frame, and there are two groups of sprockets. The two groups of sprockets are respectively connected to the worm gear transmission at the corresponding ends through transmission chains, and the two groups of worm gear transmission mechanisms simultaneously act on the rotation or braking process of the rotating inner frame.

[0017] The resulting technical effect is: due to the deadweight of the equipment, two sets of worm gear transmission mechanisms are arranged at both ends of the rotating outer frame. The rotation process of the rotating inner frame is simultaneously acted on by the two sets of worm gear transmission mechanisms. Based on the self-locking property of the worm gear, the stability of the transmission mechanism can be guaranteed when the rotating inner frame rotates and reverses, avoiding damage to components. The transmission effect at both ends can also improve the rotation controllability of the rotating inner frame.

[0018] Preferably, there are multiple groups of fixing seats arranged on the inner circumference of the rotating inner frame, the fixing seat is provided with a side U-shaped support plate, a locking plate is fixed on the U-shaped support plate, an arc groove for locking the mold branch pipe is provided on the locking plate, bolt holes are provided on the bottom wall of the U-shaped support plate and on both sides of the locking plate, U-shaped screws are connected in the bolt holes, and the mold branch pipe is fixed to the locking plate by multiple U-shaped screws.

[0019] The resulting technical effect is: the fixed seat is used to support the fixed mold, the positioning plate on the fixed seat can realize the positioning support of the mold branch pipe, and rely on the arc groove of the positioning plate to bear most of the weight of the mold, reducing the load force of the U-shaped screw, thereby improving the connection reliability between the mold and the rotating inner frame. It can be understood that the mold is side-entry installed on multiple fixed seats, and most of the load is directly transferred from the fixed seat to the rotating inner frame, avoiding large load forces on the connecting parts and extending their service life.

[0020] Preferably, the rotating outer frame and the rotating inner frame are both square frame structures.

[0021] The resulting technical effect is that the equipment does not require a counterweight structure, and the rotating outer frame and the rotating inner frame give full play to the space advantage, which can realize the installation and positioning of super-large molds, thereby realizing the molding of super-large workpieces, and greatly reducing the space size of the rotational molding machine.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See the attached Figures 1 to 5 According to an embodiment of the present invention, a dual-axis rotating frame structure for forming an electrolyte container of a flow battery comprises:

[0030] A mobile base 1, with vertical frames 2 fixed on both sides of the mobile base 1, an outer frame rotating motor 3 and an inner frame rotating motor 4 fixed on the vertical frame on one side, the two power sources drive the outer frame and the inner frame to rotate respectively without interfering with each other;

[0031] Rotating outer frame 5, rotating outer frame 5 is located between two vertical frames, and the middle parts of the two side ends of rotating outer frame 5 are respectively connected with rotating shaft 6 and hollow shaft 7, rotating shaft 6 and hollow shaft 7 are respectively rotatably mounted on vertical frame 2 through bearings, and two-point support can provide a more stable rotation basis of outer frame, and can also improve the load capacity of outer frame, and adapt to the production and manufacturing needs of super-large workpieces, and hollow shaft 7 is close to one side vertical frame where motor is arranged, and hollow shaft 7 is transmission connected with the output end of outer frame rotating motor 3 and promotes the rotating outer frame 5 to rotate; the inner side of hollow shaft 7 is rotated with power connecting shaft 8, and power connecting shaft 8 is transmission connected with the output end of inner frame rotating motor 4, and it should be noted that the rotation of power connecting shaft and the rotation of hollow shaft do not affect each other, thereby realizing the independent driving effect of rotating outer frame 5 and rotating inner frame 9 respectively;

[0032] The rotating inner frame 9 is located inside the rotating outer frame 5. The two ends of the rotating inner frame 9 are rotatably connected to the two ends of the rotating outer frame 5 through the support shaft 10. The rotation direction of the rotating inner frame 9 is perpendicular to the rotation direction of the rotating outer frame 5. The purpose is to realize the continuous rotation process of the mold along two mutually perpendicular axes, thereby completing the rotational molding production process. The rotating inner frame 9 is provided with four fixing seats 11 for installing the mold 17. These fixing seats realize the fixed assembly of the mold 17 and the rotating inner frame 9.

[0033] The worm gear transmission mechanism 12 is installed on the rotating outer frame 5. The worm wheel 121 in the worm gear transmission mechanism 12 rotates synchronously with the support shaft 10. The worm 122 in the worm gear transmission mechanism 12 is connected to the power connection shaft 8. Based on the self-locking property of the worm gear transmission, the rotating inner frame 9 can be effectively braked, and the commutation process of the rotating inner frame is further facilitated. Another advantage of the worm gear transmission mechanism is that only a small driving force is required to obtain a large torque output effect, which can reduce the specification requirements of the inner frame rotating motor and reduce power consumption and cost.

[0034] In other embodiments, a motor base 13 is fixed on the stand 2 on one side, and the outer frame rotating motor 3 and the inner frame rotating motor 4 are arranged in upper and lower layers and fixed on the motor base 13 respectively, or they can be arranged in parallel. The specific arrangement forms are various and can be selected according to the actual installation environment. A double-row chain drive is adopted between the output shaft of the outer frame rotating motor 3 and the hollow shaft 7, which can provide a large torque transmission force to meet the power requirement for rotating the outer frame.

[0035] In some other embodiments, one end of the power connection shaft 8 is coaxially fixedly connected to the output shaft of the inner frame rotating motor 4, and a sprocket is connected to the outer wall of the other end of the power connection shaft 8, and a transmission chain 14 is connected to the sprocket. The transmission chain 14 is connected to the worm 122 for transmission. The sprocket chain transmission can reduce spatial limitations and adapt to harsh transmission environments.

[0036] In some other specific embodiments, there are two groups of worm gear transmission mechanisms 12 and they are respectively arranged on the outer sides of the two ends of the rotating outer frame 5, there are two groups of sprockets, and the two groups of sprockets are respectively connected to the worm 122 at the corresponding ends through the transmission chain 14, and the two groups of worm gear transmission mechanisms 12 simultaneously act on the rotation or braking process of the rotating inner frame 9. It can be understood that the rotation of the rotating inner frame is achieved by relying on the worm gear transmission mechanisms at both ends. The transmission mode driven at both ends is reliable, which can improve the controllability of the rotating inner frame and also has a more stable braking effect during rotation reversal.

[0037] In other embodiments, there are four groups of fixing seats 11 and they are arranged on the inner circumference of the rotating inner frame 9; a side U-shaped support plate 111 is provided on the fixing seat 11; a locking plate 112 is fixed on the U-shaped support plate 111; an arc-shaped groove 113 for locking the mold branch pipe 16 is provided on the locking plate 112; bolt holes are provided on the bottom wall of the U-shaped support plate 111 and on both sides of the locking plate 112; U-shaped screws 15 are connected to the bolt holes; the mold branch pipe 16 is fixed to the locking plate 112 by a plurality of U-shaped screws; when the mold is installed, the mold branch pipe is embedded in the arc-shaped groove of the locking plate; most of the mold load is directly transferred from the fixing seat to the rotating inner frame, which can reduce the load of the screw connector and improve the installation reliability of the mold.

[0038] In some other embodiments, the rotating outer frame 5 and the rotating inner frame 9 are both square frame structures.

[0039] This device does not require a counterweight structure, which greatly reduces the space size of the rotational molding machine. The mobile base makes it easy for the entire equipment to enter the heating chamber to complete the rotational molding production process. The double-point support effect of the rotating outer frame is achieved through the double brackets, which can improve the load capacity of the frame and the vibration resistance of the frame to meet the molding production requirements of super-large workpieces. The stable support can also avoid the vibration impact problem on the equipment caused by the flow of materials in the mold during the rotation, thereby ensuring the long-term use and reliability of the molding equipment.

[0040] As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0041] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
