Description

Technical Field

[0001] This utility model belongs to the field of copper tube processing technology, specifically relating to a copper tube annealing conveyor system. Background Technology

[0002] Annealing is a crucial process in copper tube production. Its main purpose is to recrystallize the internal grains of the copper tube by heating and holding it at a specific temperature, eliminating work hardening, and improving the mechanical properties of the copper tube, such as increasing plasticity and reducing hardness, making it easier to process and shape in subsequent steps. During annealing, the copper tube is placed in a specific annealing furnace and heated, held, and cooled according to a predetermined heating curve to complete the annealing process.

[0003] After annealing, copper tubes need to be transported from the annealing furnace to a designated placement location for subsequent processing or storage. Currently, a material rack is commonly used to transport the annealed copper tubes. The material rack is equipped with multiple sets of conveyor rollers arranged side by side at intervals. These conveyor rollers are driven by a motor to rotate, thereby transporting the annealed copper tubes along the axial direction of the conveyor rollers. For example, an automatic loading and unloading rack for copper tube annealing disclosed in Chinese Utility Model Patent No. CN221940575U includes a fixed frame, an annealing furnace installed at the upper end of the fixed frame, a conveyor rack running through the interior of the annealing furnace, a conveying mechanism installed inside the conveyor rack, a guide plate at the tail end of the conveyor mechanism, and a collection box below the guide plate. The conveyor mechanism transports the annealed copper tubes along the corresponding guide plates to the collection box, realizing the collection of copper tubes.

[0004] In actual production, due to the numerous processing steps involved in copper tube manufacturing, the equipment for each step is mostly arranged side-by-side, occupying a significant amount of horizontal space in the factory. This results in the tail end of the aforementioned conveying mechanism being close to the edge of the factory wall, necessitating the placement of the copper tube collection structure on the side. The conveying mechanism cannot directly transport the annealed copper tubes to the collection structure. In this situation, to place the copper tubes at the target location, workers must manually move them from the racks. Manual handling has several drawbacks: First, it is inefficient, requiring workers to frequently travel between the racks and the target location, consuming considerable time and energy. Second, it is physically demanding, with prolonged handling work easily leading to worker fatigue and increasing the risk of workplace injuries. Third, manual handling may cause scratches, collisions, and other damage to the copper tube surface, affecting its quality. Finally, this method makes it difficult to automate and intelligentize the production process, contradicting the modern industrial production trend towards high efficiency and precision. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a copper tube annealing conveying rack system to solve the technical problems of low copper tube transfer efficiency and high manual labor intensity caused by the inability to directly transport annealed copper tubes to the target location when the existing copper tube annealing rack encounters unreasonable factory planning or limited factory space.

[0006] To solve the above problems, the copper tube annealing conveyor system provided by this utility model adopts the following technical solution:

[0007] A copper tube annealing conveyor system includes a base and a feeding rack, a transfer rack, and a feeding rack mounted on the base.

[0008] The unloading rack is equipped with multiple conveying rollers arranged side by side at intervals in the left and right direction. The conveying rollers are used to transport copper tubes after they have been annealed in the annealing furnace.

[0009] The transfer rack is used to transfer the copper tube to the feeding rack. It includes multiple support beams arranged side by side and spaced apart to support the copper tube. The transfer rack is provided with a lifting drive unit connected to the support beams to realize the lifting of the support beams. The base is provided with a transfer drive unit connected to the transfer rack to drive the transfer rack to move in the front and back direction. The support beams are used to move back and forth in the gap space between two adjacent conveying rollers.

[0010] The feeding rack is located on the rear side of the unloading rack. The feeding rack has clearance space for the support beam to pass through. The feeding rack is also equipped with a feeding and conveying mechanism for transporting the copper pipes on the transfer rack to the copper pipe collection structure.

[0011] Furthermore, the transfer rack includes a base frame and multiple sets of transfer columns arranged at left and right intervals on the base frame. Each set of transfer columns corresponds to a support beam, and the support beam guides and cooperates with the corresponding set of transfer columns in the vertical direction. The lifting drive components are fixed in groups on the base frame, and each set of lifting drive components corresponds to a support beam. The output end of the lifting drive component is connected to the corresponding support beam.

[0012] Furthermore, both ends of the support beam are connected to guide columns, and the transfer columns are provided with guide grooves extending in the vertical direction. Guide columns are connected to guide crossbars that extend into the guide grooves.

[0013] Furthermore, the support beam gradually tilts upward from front to back, and the feeding and conveying mechanism gradually tilts downward from front to back.

[0014] Furthermore, the base is provided with a track, and the base frame is provided with track wheels that cooperate with the track.

[0015] Furthermore, both the lifting drive and the transfer drive are hydraulic cylinders.

[0016] Furthermore, the feeding rack includes multiple sets of feeding columns arranged at intervals along the left-right direction, and feeding inclined beams fixed to the top of each set of feeding columns. The feeding inclined beams gradually slope downwards from front to back. Each feeding inclined beam is equipped with the feeding conveying mechanism. The gap between two adjacent feeding inclined beams forms the clearance space. Two adjacent feeding inclined beams are connected by multiple reinforcing beams arranged at intervals in the front-back direction. The reinforcing beam located at the frontmost side forms a limiting beam for limiting the movement of the transfer rack.

[0017] Furthermore, the feeding and conveying mechanism is a belt conveying mechanism, including pulleys rotatably mounted at both ends of the feeding inclined beam, a feeding belt connected between the two pulleys, and a feeding motor fixed at one end of the feeding inclined beam. The feeding belt is wrapped in a loop around the corresponding feeding inclined beam.

[0018] Furthermore, the feeding column is provided with a support rod for supporting the feeding belt.

[0019] Furthermore, multiple feeding racks are arranged at intervals in the left-right direction, and the clearance space is formed between any two adjacent feeding racks.

[0020] The beneficial effects of this utility model's copper tube annealing conveyor system are:

[0021] This utility model sets up a feeding rack on the rear side of the unloading rack, and uses a transfer rack to transfer the annealed copper tubes on the unloading rack to the feeding rack, which then delivers them to the copper tube collection structure. This does not occupy the horizontal space of the factory building. At the same time, the reasonable layout avoids the manual handling of copper tubes, realizing the automated transportation of copper tubes in a limited space, reducing labor intensity and saving labor costs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0029] An embodiment of the copper tube annealing conveyor system provided by this utility model:

[0030] like Figure 1 As shown, the copper tube annealing conveyor system 3 includes a base and a feeding rack 1, a transfer rack 2, and a feeding rack 3 mounted on the base. The feeding rack 1 is used to convey copper tubes after annealing in the annealing furnace; the feeding rack 3 is located behind the feeding rack 1; the transfer rack 2 can move back and forth between the feeding rack 1 and the feeding rack 3 to transfer the copper tubes on the feeding rack 1 to the feeding rack 3; the feeding rack 3 then conveys the copper tubes to the copper tube collection structure 6.

[0031] Specifically, the unloading rack 1 is equipped with multiple conveyor rollers 11 arranged side-by-side at intervals in the left-right direction via bearing seats and bearings. Each pair of adjacent conveyor rollers 11 has a corresponding sprocket connected to its roller shaft, and a chain connects the two corresponding sprockets. The roller shaft of the rightmost conveyor roller 11 is connected to a drive motor. Through the cooperation of the sprocket and the chain, each conveyor roller 11 rotates, thereby conveying the annealed copper tube.

[0032] like Figure 2As shown, the transfer rack 2 includes a base frame 21, multiple sets of transfer columns 22 arranged at intervals in the left-right direction on the base frame 21, and support beams 23 corresponding to the top of each set of transfer columns 22. The support beams 23 are arranged side-by-side at intervals in the left-right direction. The support beams 23 gradually slope upwards from front to back. A set of lifting drive components 4 is fixed on the base frame 21 at the position corresponding to each set of transfer columns 22. Each set of lifting drive components 4 consists of two components, arranged at intervals in the front-back direction. The output ends of the two lifting drive components 4 in each set are connected to the corresponding support beam 23, thereby realizing the lifting and lowering of the support beam 23. To ensure the stability of the lifting and lowering of the support beam 23, the support beam 23 is guided and cooperates with the corresponding set of transfer columns 22 in the vertical direction. Specifically, guide columns 24 are welded to both the front and rear ends of the support beam 23. The transfer columns 22 have guide grooves extending in the vertical direction, and guide crossbars 25 extending into the guide grooves are connected to the guide columns 24.

[0033] like Figure 1 and Figure 2 As shown, the base 7 is provided with a track 71 extending in the front-to-back direction, and the base frame 21 is provided with track wheels 26 that cooperate with the track 71. The base 7 is also provided with a transfer drive component 5. In this embodiment, both the transfer drive component 5 and the lifting drive component 4 are hydraulic cylinders. One end of the transfer drive component 5 is fixed to the base 7, and the other end is connected to the base frame 21, which is used to drive the transfer rack 2 to move back and forth. The support beam 23 is located in the gap between two adjacent conveying rollers 11, and will not interfere with the unloading rack 1 and its structure during the front-to-back movement.

[0034] The feeding rack 3 includes multiple sets of feeding columns 37 spaced apart in the left-right direction, and feeding inclined beams 31 fixed to the top of each set of feeding columns 37. The feeding inclined beams 31 gradually slope downward from front to back. Each feeding inclined beam 31 is equipped with a feeding conveying mechanism, which also causes the feeding conveying mechanism to gradually slope downward from front to back. The space between two adjacent feeding inclined beams 31 forms a clearance space, allowing the support beam 23 to pass through. Two adjacent feeding inclined beams 31 are connected by multiple reinforcing beams 36 spaced apart in the front-back direction. The reinforcing beam 36 located at the foremost position forms a limiting beam for limiting the movement of the transfer rack 2, meaning that when the transfer rack 2 moves in the front-back direction, it can only move to the position of the foremost reinforcing beam 36 at most.

[0035] In this embodiment, as Figure 3As shown, the feeding and conveying mechanism is a belt conveyor mechanism, including pulleys 34 rotatably mounted at both ends of the feeding inclined beam 31, a feeding belt 32 connected between the two pulleys 34, and a feeding motor 33 fixed to one end of the feeding inclined beam 31. The feeding belt 32 is wrapped in a loop around the corresponding feeding inclined beam 31. Because the feeding inclined beam 31 is relatively long, a support rod 35 is also provided on the feeding column to support the feeding belt 32 in order to prevent the feeding belt 32 from sagging.

[0036] A copper tube collection structure 6 is set at the end of the feeding rack 3, and the annealed copper tubes are then transferred to the copper tube collection structure 6 through the feeding rack 3.

[0037] The specific working process of the copper tube annealing conveyor rack system 3 of this utility model is as follows:

[0038] Initially, each support beam 23 is located in the gap between two adjacent conveyor rollers 11 and below them. The annealed copper tube is conveyed from right to left by the conveyor rollers 11. When it reaches the position near the left end of the unloading rack 1, each lifting drive 4 extends upward, driving each support beam 23 to rise until the copper tube is lifted to the position where it is separated from the conveyor rollers 11. Then, the transfer drive 5 extends, causing the transfer rack 2 to move backward as a whole. Although the support beams 23 tilt upward from front to back, the tilt is very small. The copper tube will slowly fall under its own weight. When the transfer rack 2 stops with the aforementioned limiting beam, the lifting drive 4 retracts, and the support beams 23 descend until the copper tube falls onto the feeding belt 32 and is conveyed to the copper tube collection structure 6 by the running feeding belt 32. It should be noted that, since the inclination direction of the support beam 23 is opposite to that of the inclination direction of the feeding beam 31, there will be a buffer when the copper tube falls from the support beam 23 onto the feeding belt 32, and then it will be conveyed obliquely downward by the feeding belt 32 to the copper tube collection structure 6.

[0039] In other embodiments, the feeding and conveying mechanism may also take the form of multiple conveying rollers 11 arranged side by side. In this case, the feeding and conveying mechanism does not need to be inclined and can achieve the conveying operation of copper tubes even when arranged horizontally.

[0040] In other embodiments, the lifting drive 4 and the transfer drive 5 may also be cylinders.

[0041] In other embodiments, multiple transfer racks 2 can be arranged side by side in the left and right directions. Each transfer rack 2 can be moved back and forth by a single transfer drive 5. Alternatively, multiple transfer racks 2 can be connected together and moved back and forth as a whole by a single transfer drive 5.

[0042] In other embodiments, the inclination direction of the support beam 23 may be the same as that of the feeding and conveying mechanism, both inclining downwards from front to back.

[0043] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "back," "left," and "right," which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not imply that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as a limitation on the present invention.

[0044] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
