Abstract
Description
Technical Field
[0001] This utility model relates to the field of reel equipment technology, and in particular to a follow-up reel device. Background Technology
[0002] Reeling devices are widely used for winding and packaging materials such as cables, hoses, and LED strips. However, traditional reeling devices typically separate the reel's movement from the movement of other mechanisms, resulting in sluggish reel movement and making operation inconvenient. Furthermore, separating the reel's movement from other mechanisms means that at least two operators are required, leading to high labor costs. Utility Model Content
[0003] Therefore, it is necessary to provide a follow-up reel device that can accurately synchronize the movement of other mechanisms and reduce labor costs.
[0004] A follow-up reel device includes a base frame, a reel body, a hydraulic motor, a first one-way solenoid valve, a second one-way solenoid valve, a pressure relief valve, and a load-sensitive proportional multi-way valve. The shaft of the reel body is rotatably mounted on the base frame. The reel body has a winding section circumferentially arranged along its shaft for winding and storing linear material. The load-sensitive proportional multi-way valve has an inlet port P, a return port R, a first working port A, a first working port B, a second working port A, and a second working port B. The first working port A is connected to the inlet port of the hydraulic motor. One end of the first one-way solenoid valve is connected to the first working port B, and the other end is connected to the return port of the hydraulic motor and one end of the second one-way solenoid valve, respectively. The other end of the second one-way solenoid valve is connected to one end of the pressure relief valve. The other end of the pressure relief valve is connected to an oil tank. The second working port A and the second working port B are respectively connected to the inlet and return ports of the drive motors of other motion mechanisms.
[0005] The aforementioned follow-up reel device has three states: stationary, unloading, and rewinding. In the stationary state, the external motion mechanism is also stationary. The linear material is retracted and wound into the winding section. At this time, the hydraulic motor, the first one-way solenoid valve, the second one-way solenoid valve, and the load-sensitive proportional multi-way valve are all inactive. Because of the presence of the first and second one-way solenoid valves, the oil in the oil circuit of the follow-up reel device does not flow, so the reel body naturally does not rotate.
[0006] When in the unloading state, the first and second one-way solenoid valves are opened while the external motion mechanism is moving. The reel body is in a retractable and unloading state. At this time, the load-sensitive proportional multi-way valve and the hydraulic motor are not working. The external motion mechanism drives the reel body to unload. At this time, the reel body will drive the output shaft of the hydraulic motor to rotate in the opposite direction, which will cause the internal oil circuit of the follow-up reel device to form a back pressure state, generating a reverse retraction force to ensure that the reel body always maintains the same speed as the external motion mechanism and will not over-unload.
[0007] When in the take-up state, both the first and second one-way solenoid valves are inactive, while the hydraulic motor and the load-sensitive proportional multi-way valve are active. As the external motion mechanism moves, the load-sensitive proportional multi-way valve drives the hydraulic motor, which in turn drives the reel body to begin take-up. Simultaneously, the pressure relief valve senses the internal pressure in the internal oil circuit of the follow-up reel device. When the internal pressure reaches a preset value, the pressure is released, thereby controlling the take-up force generated by the hydraulic motor and preventing excessive take-up force from causing the external motion mechanism to move.
[0008] Therefore, the aforementioned follow-up reel device solves the problem of motion lag in traditional reel devices, realizes the follow-up function, and can move in precise synchronization with external motion mechanisms. Thus, the control operation can be integrated into an external control system, enabling single-person operation and effectively reducing labor costs. Attached Figure Description

[0020] Please see Figures 1 to 3 Please see Figure 1 The following reel device 100 in the preferred embodiment of this utility model includes a base frame 110, a reel body 120, a hydraulic motor 130, a first one-way electromagnetic switch valve 140, a second one-way electromagnetic switch valve 150, a pressure relief valve 160, and a load-sensitive proportional multi-way valve 170.
[0021] Please refer to the following: Figure 4 The reel body 120 has its shaft 122 rotatably mounted on the base frame 110. The reel body 120 has a winding section 121 circumferentially arranged along its shaft 122 for winding and storing linear material 10. The load-sensitive proportional multi-way valve 170 has an inlet port P 171, a return port R 172, a first working port A 173, a first working port B 174, a second working port A 175, and a second working port B 176. The first working port A 173 is connected to the inlet port of the hydraulic motor 130. One end of the first one-way solenoid valve 140 is connected to the first working port B 174, and the other end is connected to the return port of the hydraulic motor 130 and one end of the second one-way solenoid valve 150. The other end of the second one-way solenoid valve 150 is connected to one end of the pressure relief valve 160. The other end of the pressure relief valve 160 is connected to the oil tank 30. The second working port A 175 and the second working port B 176 are used to connect to the oil inlet and return ports of the drive motor 20 of other motion mechanisms, respectively. Specifically, the oil inlet port P 171 is used to connect to the output port of an external delivery pump, and the oil return port R 172 is used to connect to the oil tank 30. The linear material 10 can be a hose, cable, wire rope, water hose, etc., and the other motion mechanisms can be a winch device, etc.
[0022] The aforementioned follow-up reel device 100 has three states: stationary, unloading, and rewinding. In the stationary state, the external motion mechanism is also stationary. The linear material 10 is retracted and wound into the winding section 121. At this time, the hydraulic motor 130, the first one-way solenoid valve 140, the second one-way solenoid valve 150, and the load-sensitive proportional multi-way valve 170 are all inactive. Due to the installation of the first one-way solenoid valve 140 and the second one-way solenoid valve 150, the oil in the return oil circuit of the hydraulic motor 130 does not flow. Therefore, the reel body 120 can only perform the rewinding action, and the unloading action is prohibited to ensure that the follow-up reel device 100 will not release the linear material 10 in the stationary state. The entire machine is in a state where unloading is prohibited.
[0023] When in the unloading state, while the external motion mechanism is moving, the first one-way solenoid valve 140 and the second one-way solenoid valve 150 are energized and opened, and the reel body 120 is in a retractable and unloading state. At this time, the load-sensitive proportional multi-way valve 170 and the hydraulic motor 130 are both in a non-working state. At this time, the external motion mechanism can drive the reel body 120 to perform unloading work. During the unloading process, the reel body 120 will drive the output shaft of the hydraulic motor 130 to rotate in the opposite direction, thereby causing the internal oil circuit of the follow-up reel device 100 to form a back pressure state, generating a reverse reloading force to ensure that the reel body 120 always maintains the same speed as the external motion mechanism and will not over-unload.
[0024] When in the material receiving state, both the first one-way solenoid valve 140 and the second one-way solenoid valve 150 are inactive, while the hydraulic motor 130 and the load-sensitive proportional multi-way valve 170 are active. As the external motion mechanism moves, the load-sensitive proportional multi-way valve 170 drives the hydraulic motor 130 to work, which in turn drives the reel body 120 to start the material receiving process. At the same time, the pressure relief valve 160 senses the internal pressure in the internal oil circuit of the follow-up reel device 100. When the internal pressure reaches the preset pressure value, the pressure is released, thereby controlling the material receiving force generated by the hydraulic motor 130 and preventing the material receiving force from being too large and causing the external motion mechanism to move.
[0025] Therefore, the aforementioned follow-up reel device 100 solves the problem of motion lag in traditional reel devices, realizes the follow-up function, and can move in precise synchronization with external motion mechanisms. Thus, the control operation can be integrated into an external control system, enabling single-person operation and effectively reducing labor costs.
[0026] In some embodiments, the reel body 120, hydraulic motor 130, first one-way solenoid valve 140, second one-way solenoid valve 150, and pressure relief valve 160 are multiple units that correspond one-to-one with each other. The first working port A 173 and the second working port B 176 are multiple units that correspond one-to-one with each other. The multiple hydraulic motors 130 are respectively connected to the rotating shafts 122 of the multiple reel bodies 120 in a corresponding manner. The oil inlets of the multiple hydraulic motors 130 are respectively connected to the multiple first working ports A 173 in a corresponding manner. The multiple first working ports B 174 are respectively connected to one end of the multiple first one-way solenoid valves 140 in a corresponding manner. The other end of each first one-way solenoid valve 140 is respectively connected to the oil return port of the corresponding hydraulic motor 130 and one end of the corresponding second one-way solenoid valve 150. The other end of each second one-way solenoid valve 150 is connected to one end of the corresponding pressure relief valve 160.
[0027] Thus, multiple hydraulic motors 130, multiple first one-way solenoid valves 140, multiple second one-way solenoid valves 150, multiple pressure relief valves 160, and a load-sensitive proportional multi-way valve 170 together constitute multiple control oil circuits for separately controlling the movement of multiple reel bodies 120, thereby realizing the follow-up function of multiple reel bodies 120. In practical applications, by controlling the opening and closing of all or part of the hydraulic motors 130, first one-way solenoid valves 140, and second one-way solenoid valves 150 in the control oil circuit, the feeding, unloading, and take-up operations of all or part of the reel bodies 120 can be selected.
[0028] In some embodiments, the first one-way solenoid valve 140, the second one-way solenoid valve 150, and the pressure relief valve 160 are all integrated into the valve block 180 to obtain an integrated electromagnetic hydraulic lock valve block 190. The surface of the valve block 180 has a third working port A 181, a third working port B 182 connected to one end of the first one-way solenoid valve 140, a return port T 183 connected to the other end of the pressure relief valve 160, a fourth working port A 184 connected to the other end of the first one-way solenoid valve 140 and one end of the second one-way solenoid valve 150, and a fourth working port B 185 connected to the third working port A 181. The third working port A 181 and the third working port B 182 are connected to the first working port A 173 and the first working port B 174, respectively. The return port T 183 is used to connect to the oil tank 30. The fourth working port A 184 and the fourth working port B 185 are connected to the oil inlet and oil return port of the hydraulic motor 130, respectively.
[0029] In this way, the first one-way solenoid switch valve 140, the second one-way solenoid switch valve 150, and the pressure relief valve 160 are all integrated into a valve block 180 to obtain an electromagnetic hydraulic lock integrated valve block 190. This not only reduces the space occupied by the hydraulic oil circuit in the follow-up reel device 100, but also simplifies the manufacturing process of the follow-up reel device 100.
[0030] Please refer to it again. Figure 1 In some embodiments, the follow-up reel device 100 further includes a transmission assembly 201. The transmission assembly 201 includes a first sprocket 2011, a second sprocket 2012, and a transmission chain 2013. The first sprocket 2011 and the second sprocket 2012 are respectively connected to the output shaft of the hydraulic motor 130 and the rotating shaft 122 of the reel body 120. One end of the transmission chain 2013 is sleeved on the outside of the first sprocket 2011 and engages with it, while the other end is sleeved on the outside of the second sprocket 2012 and engages with it.
[0031] Thus, the hydraulic motor 130 and the rotating shaft 122 of the reel body 120 are connected by chain drive, which ensures the precise control of the hydraulic motor 130 on the movement of the reel body 120, making the synchronization of the follow-up reel body 120 with other motion mechanisms more precise.
[0032] In other embodiments, the output shaft of the hydraulic motor 130 can also be connected to the rotating shaft 122 of the reel body 120 via belt drive, gear drive, or other means.
[0033] Please refer to the following: Figure 5 In some embodiments, the base frame 110 includes a base 111 and two support frames 112. The two support frames 112 are axially spaced on the base 111 along the pivot 122 of the reel body 120. Mounting holes 1121 are provided on the support frames 112. The reel body 120 is located between the two support frames 112, and both ends of its pivot 122 are rotatably mounted in the mounting holes 1121. Thus, by positioning the reel body 120 between the two support frames 112 and above the base 111, the follow-up reel device 100 can remain stable throughout the entire winding and unwinding process.
[0034] Please refer to it again. Figure 4 In some embodiments, the reel body 120 includes a rotating shaft 122 and two protective structures 123. The two protective structures 123 are fixed to the rotating shaft 122 at circumferential intervals. The two protective structures 123 and the sidewalls of the rotating shaft 122 form a winding portion 121. In this way, the reel body 120 is divided into three parts: the rotating shaft 122 and the two protective structures 123, and formed separately, thereby reducing the processing difficulty of the reel body 120, reducing material waste during processing, and lowering processing costs.
[0035] Please refer to the following: Figure 6 Furthermore, in some embodiments, the protective structure 123 includes an outer ring 1231, an inner ring 1232 located within the outer ring 1231, and a plurality of spokes 1233 connecting the outer ring 1231 and the inner ring 1232. The plurality of spokes 1233 are arranged radially along the circumference of the inner ring 1232. The inner ring 1232 is fitted onto and fixed to the rotating shaft 122. Of course, in other embodiments, the protective structure 123 can also be a single plate or other structures. Specifically, the outer ring 1231 and the inner ring 1232 are concentrically arranged. Of course, in other embodiments, the outer ring 1231 and the inner ring 1232 can be non-axial or non-concentric, as long as the inner ring 1232 is within the outer ring 1231.
[0036] Thus, spaces are formed between the outer ring 1231, the inner ring 1232, and the two adjacent spokes 1233. Therefore, the protective structure 123 is a hollow frame structure, which ensures that the protective structure 123 can protect and limit the linear material 10 while also making the protective structure 123 strong, stable, and lightweight. This helps to reduce the weight of the reel body 120, thereby making it easier for the follow-up reel device 100 to perform material feeding and unloading operations.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
