Description

Technical Field

[0001] This utility model relates to the field of aluminum profile production technology, and in particular to an aluminum rod conveying device for an aluminum rod cutting machine. Background Technology

[0002] In the aluminum rod processing industry, the aluminum rod cutting machine is a key piece of equipment, and the performance of its supporting conveying mechanism directly affects production efficiency and product quality. Traditional aluminum rod cutting production lines typically use gravity conveying, guiding the cut aluminum rods to a collection device via inclined conveyor troughs. However, existing conveying methods have revealed many technical problems that urgently need to be solved in practical applications.

[0003] In the prior art, Chinese patent with patent number CN201921141502.0 discloses an aluminum rod conveying trough for an aluminum rod cutting machine, including a support base plate and an aluminum rod conveying trough disposed on one side of the support base plate. A cylinder is disposed above the support base plate and an aluminum rod placement trough disposed on one side of the cylinder for receiving aluminum rods. The aluminum rod conveying trough is used to receive aluminum rods falling from the aluminum rod placement trough. The aluminum rod conveying trough includes a main base plate for supporting aluminum rods and side plates disposed on the left and right sides of the main base plate. The cylinder is used to impact the aluminum rod placement trough.

[0004] While the aforementioned existing technologies have solved the problem of the narrow conveying trough being inconvenient for conveying aluminum bars, the following shortcomings still exist in practical use: First, the cylinder directly impacts one side of the placement trough, causing it to easily shake during unloading, especially when handling large-diameter or long aluminum bars, where this instability is more pronounced. Second, the aluminum bar conveying trough only conveys aluminum bars through an inclined base plate, resulting in low conveying efficiency and poor stability during the conveying process, easily leading to tilting and further affecting conveying efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, such as poor stability of aluminum rod conveying and the tendency of aluminum rods to tilt, and to provide an aluminum rod conveying device for an aluminum rod cutting machine.

[0006] This utility model is achieved through the following technical solution: an aluminum rod conveying device for an aluminum rod cutting machine, comprising a frame body, on which a conveyor for conveying aluminum rods is provided; an aluminum rod placement groove is provided at one end of the frame body near the feed end of the conveyor, and a discharge port is provided on the side of the aluminum rod placement groove near the conveyor; a door is provided at the discharge port, the bottom end of the door is rotatably connected to the bottom end of the discharge port by a hinge, and a latch for fixing the door is provided on the aluminum rod placement groove; a connecting shaft is provided above the discharge end of the conveyor, and two support mechanisms are respectively connected to the two ends of the connecting shaft, and the two support mechanisms are respectively installed on the frame body on both sides of the conveyor; a plurality of spaced blocking rollers are provided on the connecting shaft, and the wheel surface of the blocking rollers is close to the conveying surface of the conveyor.

[0007] The aluminum rod placement slot described in this utility model is used for temporary storage of aluminum rods. The door and latch design facilitates control of the aluminum rods feeding onto the conveyor. The discharge can be flexibly opened or closed according to production needs, achieving orderly feeding. The blocking rollers can block and buffer the aluminum rods conveyed on the conveyor, correcting the rods and preventing them from tilting. They also prevent the rods from rushing out of the conveyor due to inertia or excessive conveying speed, ensuring the safety and stability of the aluminum rod conveying process.

[0008] A further improvement of this utility model is that support rods are respectively provided on both sides of the bottom end of the aluminum rod placement groove near the door, and the top of the support rods is rotatably connected to the aluminum rod placement groove, while the bottom end of the support rods is fixedly connected to the frame body; a lifting cylinder is provided at the bottom end of the aluminum rod placement groove away from the door, and the top of the lifting cylinder is rotatably connected to the aluminum rod placement groove through a connecting mechanism, while the bottom end of the lifting cylinder is fixed to the frame body.

[0009] The support rod provides stable support for the aluminum rod placement slot, ensuring its structural stability. The lifting cylinder can adjust the tilt angle of the aluminum rod placement slot by extending and retracting. When unloading is required, the lifting cylinder rises to tilt the aluminum rod placement slot, allowing the aluminum rods to smoothly pass through the door and enter the conveyor. The unloading process is more efficient and smoother, and the tilt angle can be adjusted according to the characteristics of the aluminum rods and the conveying requirements.

[0010] A further improvement of this utility model is that the connecting mechanism includes a slider, the bottom end of which is rotatably connected to the top end of the lifting cylinder via a hinge; the bottom end of the aluminum rod placement groove is provided with a groove corresponding to the slider, and the slider is disposed inside the groove and slidably connected to the groove.

[0011] The cooperation between the slider and the groove allows the aluminum rod placement groove to tilt relatively smoothly during the extension and retraction of the lifting cylinder, avoiding jamming or shaking. This sliding connection method can adapt to the positional changes of the aluminum rod placement groove during the tilting process, ensuring that the force of the lifting cylinder can be effectively transmitted to the aluminum rod placement groove, thereby achieving smooth angle adjustment.

[0012] A further improvement of this utility model is that the support mechanism includes a fixed frame installed on the frame body, a movable plate is provided inside the fixed frame, the two ends of the movable plate are slidably connected to the inner walls on both sides of the fixed frame, and the side of the movable plate near the connecting shaft is rotatably connected to the end of the connecting shaft through a bearing; a lead screw is screwed into the center of the movable plate through a threaded through hole, the lead screw passes through the movable plate, and the top end of the lead screw rotates through the top end of the fixed frame through a bearing and is connected to a handle, and the bottom end of the lead screw is rotatably connected to the inner bottom end of the fixed frame through a bearing.

[0013] By turning the handle, the lead screw rotates, and the threaded engagement between the lead screw and the moving plate causes the moving plate to move up and down within the fixed frame, thereby adjusting the height of the connecting shaft and the blocking rollers. The position of the blocking rollers can be flexibly adjusted according to the diameter of the aluminum rod and the conveying requirements, improving the adaptability of the conveying mechanism to aluminum rods of different specifications and enhancing the controllability of the conveying process.

[0014] A further improvement of this invention is that the support mechanism also includes a base, with the fixed frame fixed to the base. The base is detachably mounted on the frame body via bolts. This detachable installation method facilitates the installation, disassembly, and maintenance of the support mechanism. When the support mechanism malfunctions or requires adjustment, it can be quickly removed from the frame body, facilitating repair and replacement of parts, thus improving the maintainability and service life of the equipment.

[0015] A further improvement of this utility model is that a support shaft is provided on the frame body between the aluminum rod placement groove and the feed end of the conveyor. The support shaft is used to support the open door so that the open door can maintain an inclined state.

[0016] The support shaft provides support for the opened door, maintaining its stable tilt and ensuring that the aluminum bars can smoothly slide from the aluminum bar placement slot through the door onto the conveyor. This prevents the door from wobbling or deforming during the aluminum bar's descent, ensuring the smoothness and stability of the aluminum bar conveying process.

[0017] A further improvement of this utility model is that the two ends of the support shaft are respectively connected to the fixing brackets, the two fixing brackets are located on both sides of the door opening, and the fixing brackets are detachably installed on the frame body by bolts.

[0018] The mounting bracket is detachably mounted to the frame body via bolts, facilitating the installation and removal of the support shaft. This allows for quick operation when maintenance, replacement, or repositioning of the support shaft is required, improving the maintainability and flexibility of the equipment. Furthermore, the mounting bracket's location on both sides of the door opening provides better fixation of the support shaft, ensuring its effective support for the door.

[0019] A further improvement of this utility model is that side baffles are provided on both sides of the door, and the inner wall of the side baffles slides in contact with the outer wall of the aluminum rod placement groove.

[0020] The side baffle prevents the aluminum rods from falling to either side as they slide down the aluminum rod placement slot through the door, serving as a guide and limiting element. The inner wall of the side baffle slides in contact with the outer wall of the aluminum rod placement slot, ensuring smooth operation of the door during rotation and enhancing the seal between the door and the aluminum rod placement slot, reducing the risk of jamming or blockage during unloading.

[0021] A further improvement of this utility model is that baffles are provided on both sides of the conveyor, and the baffles are installed on the frame body.

[0022] The baffle plate prevents aluminum bars from falling from both sides during conveyor transport, ensuring stable transport and improving safety and reliability. Simultaneously, the baffle plate also guides the aluminum bars, ensuring they are transported in a predetermined direction. A further improvement of this invention is that a guide chute is provided at the other end of the frame body near the conveyor outlet, and an aluminum bar collection chute is located below the guide chute.

[0023] The feed chute guides the aluminum bars conveyed by the conveyor to fall accurately into the aluminum bar collection trough, preventing the bars from scattering or shifting during discharge, thus improving the efficiency and accuracy of aluminum bar collection. The aluminum bar collection trough is used to centrally collect aluminum bars, facilitating subsequent processing and transportation.

[0024] As can be seen from the above technical solutions, the beneficial effects of this utility model are: 1. This utility model adjusts the tilt angle of the aluminum bar placement slot using a lifting hydraulic cylinder, and works in conjunction with a support shaft to stabilize the tilt state of the opening, allowing the aluminum bars to smoothly and orderly enter the conveyor from the placement slot, avoiding jamming and shaking. Simultaneously, the inclusion of blocking rollers, baffles, and side baffles prevents the aluminum bars from rushing out, falling, or shifting during conveying, ensuring efficient and stable conveying.

[0025] 2. The support mechanism described in this utility model can adjust the height of the blocking roller by rotating the handle, and can be flexibly adjusted according to the diameter of the aluminum rod and the conveying requirements, thereby enhancing the adaptability of the conveying mechanism to aluminum rods of different specifications.

[0026] 3. The base and the fixing frame of the support shaft of the bracket mechanism described in this utility model are both installed by bolts, which facilitates the installation, disassembly and maintenance of the equipment. In case of failure, parts can be quickly repaired or replaced, thus improving the maintainability and service life of the equipment. Attached Figure Description

[0034] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0035] Please refer to the attached document. Figure 1 , 25. In conjunction with specific embodiments, the following description is provided: The aluminum rod conveying device for an aluminum rod cutting machine according to this utility model includes a frame body 1, on which a conveyor 2 for conveying aluminum rods is provided; an aluminum rod placement groove 3 is provided at one end of the frame body 1 near the feeding end of the conveyor 2, and a discharge port is provided on the side of the aluminum rod placement groove 3 near the conveyor 2; a door 4 is provided at the discharge port, and the bottom end of the door 4 is rotatably connected to the bottom end of the discharge port through a hinge, and a latch for fixing the door 4 is provided on the aluminum rod placement groove 3; a connecting shaft 801 is provided above the discharge end of the conveyor 2, and two support mechanisms 9 are respectively connected to the two ends of the connecting shaft 801, and the two support mechanisms 9 are respectively installed on the frame body 1 on both sides of the conveyor 2; a plurality of spaced blocking rollers 8 are provided on the connecting shaft 801, and the wheel surface of the blocking rollers 8 is close to the conveying surface of the conveyor 2.

[0036] In the working scenario of the aluminum rod cutting machine, the aluminum rods to be cut are first placed in the aluminum rod placement slot 3. When it is necessary to transport the aluminum rods to the conveyor 2, the latch on the door 4 is opened, causing the door 4 to rotate around its bottom hinge and open, allowing the aluminum rods to roll from the discharge port onto the conveyor 2. The conveyor 2 starts, driving the aluminum rods towards the discharge end. During the conveying process, the blocking roller 8 located on the connecting shaft 801 above the discharge end of the conveyor 2, utilizing its wheel surface close to the conveying surface of the conveyor 2, acts as a barrier and buffer for the aluminum rods. During the conveying process, the aluminum rods do not pass directly; when the aluminum rods come into contact with the blocking roller 8, they pause slightly, correcting any tilting phenomenon, thus eliminating the tilting. Since the height difference between the blocking roller 8 and the conveying surface of the conveyor is not too great, only a small force is needed to push them through to overcome gravity; that is, the arrival of subsequent aluminum rods will push the preceding aluminum rods through the blocking roller 8.

[0037] This design effectively solves the problems of aluminum bars potentially slid out of the conveyor due to inertia or excessive speed in traditional conveying methods, as well as the tendency for aluminum bars to tilt, thus improving the safety and stability of the aluminum bar conveying process. Simultaneously, the placement of the aluminum bar slot 3 and the door 4 allows for flexible control of the aluminum bar conveying according to production needs, achieving orderly feeding and avoiding the impact of disorderly accumulation of aluminum bars on conveying efficiency.

[0038] For details, please refer to the appendix. Figure 1 Support rods 5 are respectively provided on both sides of the bottom end of the aluminum rod placement groove 3 near the door 4, and the top of the support rods 5 are rotatably connected to the aluminum rod placement groove 3, and the bottom end of the support rods 5 is fixedly connected to the frame body 1; a lifting cylinder 6 is provided at the bottom end of the aluminum rod placement groove 3 away from the door 4, and the top of the lifting cylinder 6 is rotatably connected to the aluminum rod placement groove 3 through a connecting mechanism, and the bottom end of the lifting cylinder 6 is fixed on the frame body 1.

[0039] When aluminum bars need to be unloaded from the aluminum bar placement trough 3 to the conveyor 2, the lifting cylinder 6 starts to work, and its piston rod extends upward. Since the top of the lifting cylinder 6 is rotatably connected to the aluminum bar placement trough 3 through a connecting mechanism, and the bottom is fixed to the frame body 1, and the top of the support rods 5 near the opening 4 on both sides of the bottom of the aluminum bar placement trough 3 is rotatably connected to the aluminum bar placement trough 3, and the bottom is fixedly connected to the frame body 1, the extension of the lifting cylinder 6 will cause the aluminum bar placement trough 3 to rotate around the top of the support rods 5, thereby making the aluminum bar placement trough 3 form a certain tilt angle.

[0040] This design overcomes the problem of uneven unloading caused by the instability of the placement trough in traditional unloading methods. By adjusting the extension and retraction of the lifting cylinder 6, the tilt angle of the aluminum rod placement trough 3 can be flexibly adjusted according to the characteristics of the aluminum rod and the conveying requirements, so that the aluminum rod can slide more smoothly from the placement trough onto the conveyor 2, improving unloading efficiency and ensuring the stability of the unloading process.

[0041] For details, please refer to the appendix. Figure 3 The support mechanism 9 includes a fixed frame 901 mounted on the frame body 1. A movable plate 904 is provided inside the fixed frame 901. The two ends of the movable plate 904 are slidably connected to the inner walls on both sides of the fixed frame 901, and the side of the movable plate 904 near the connecting shaft 801 is rotatably connected to the end of the connecting shaft 801 through a bearing. A lead screw 903 is screwed into the center of the movable plate 904 through a threaded through hole. The lead screw 903 passes through the movable plate 904, and the top end of the lead screw 903 is rotatably connected to the top end of the fixed frame 901 through a bearing and then connected to a handle 905. The bottom end of the lead screw 903 is rotatably connected to the inner bottom end of the fixed frame 901 through a bearing.

[0042] When the height of the blocking roller 8 needs to be adjusted according to the diameter of the aluminum rod and the conveying requirements, the operator turns the handle 905, which drives the lead screw 903 to rotate. Since the lead screw 903 is screwed to the moving plate 904 through a threaded through-hole, and both ends of the moving plate 904 are slidably connected to the inner walls of both sides of the fixed frame 901, the rotation of the lead screw 903 causes the moving plate 904 to move up and down within the fixed frame 901. The moving plate 904 is rotatably connected to the end of the connecting shaft 801 via a bearing, thereby driving the connecting shaft 801 and the blocking roller 8 to move up and down.

[0043] This adjustable design improves the adaptability of the conveying mechanism to aluminum bars of different specifications. Compared with the traditional fixed-height blocking structure, the position of the blocking rollers 8 can be flexibly adjusted according to the actual situation, better blocking and buffering the aluminum bars, and further enhancing the controllability and stability of the conveying process.

[0044] For details, please refer to the appendix. Figure 4A support shaft 10 is provided on the frame body 1 between the aluminum rod placement groove 3 and the feeding end of the conveyor 2. The support shaft 10 is used to support the open door 4 so that the open door 4 can be kept in an inclined state.

[0045] When the door 4 is opened, it rotates around its hinge at the bottom until it rests against the support shaft 10. The support shaft 10 is located on the frame body 1 between the aluminum rod placement slot 3 and the feed end of the conveyor 2, providing support for the opened door 4 and keeping it in a stable tilted state.

[0046] This design ensures that the aluminum rod can smoothly slide down from the aluminum rod placement groove 3 onto the conveyor 2 along the open door 4, avoiding the door 4 from shaking or deforming during the sliding of the aluminum rod, ensuring the smoothness and stability of the aluminum rod conveying, and reducing the problem of aluminum rod jamming or blockage caused by the instability of the door 4.

[0047] For details, please refer to the appendix. Figure 1 and 2 At the other end of the frame body 1, near the discharge end of the conveyor 2, there is a guide trough 11, and below the guide trough 11, there is an aluminum rod collection trough 12.

[0048] When the aluminum bars are conveyed to the discharge end by the conveyor 2, they enter the guide chute 11. The guide chute 11 guides the aluminum bars accurately into the aluminum bar collection chute 12 below, achieving centralized collection of the aluminum bars.

[0049] This design prevents aluminum rods from scattering or shifting during the discharge process, improving the efficiency and accuracy of aluminum rod collection. The aluminum rod collection trough 12 centrally collects the aluminum rods, facilitating subsequent processing and transportation, and reducing the workload and time costs associated with manual collection.

[0050] In one embodiment, reference is made to the appendix. Figure 1 and 2 The connecting mechanism includes a slider 7, the bottom end of which is rotatably connected to the top end of the lifting cylinder 6 via a hinge; the bottom end of the aluminum rod placement groove 3 is provided with a groove corresponding to the slider 7, and the slider 7 is disposed inside the groove and slidably connected to the groove.

[0051] During the tilting process of the aluminum rod placement groove 3 caused by the extension and retraction of the lifting cylinder 6, the slider 7 in the connecting mechanism slides in the groove at the bottom of the aluminum rod placement groove 3. The bottom end of the slider 7 is rotatably connected to the top end of the lifting cylinder 6 through a hinge, so that the slider 7 can adapt to the change of the movement direction of the lifting cylinder 6, and at the same time, the sliding in the groove ensures a smooth transition of the aluminum rod placement groove 3 during the tilting process.

[0052] This design effectively avoids the jamming or shaking that may occur when adjusting the angle in traditional connection methods, ensuring that the force of the lifting cylinder 6 can be effectively transmitted to the aluminum rod placement slot 3, achieving smooth angle adjustment, and thus ensuring the smoothness and stability of the aluminum rod unloading process.

[0053] In one embodiment, reference is made to the appendix. Figure 3 The support mechanism 9 also includes a base 902, and a fixing frame 901 is fixed on the base 902. The base 902 is detachably mounted on the frame body 1 by bolts.

[0054] When it is necessary to install, disassemble or maintain the support mechanism 9, simply unscrew the bolts to separate the base 902 from the frame body 1, and then operate the entire support mechanism 9.

[0055] This detachable installation method greatly improves the maintainability of the equipment. When the support mechanism 9 malfunctions or needs adjustment, it can be quickly removed from the frame body 1, facilitating maintenance and replacement of parts, reducing equipment maintenance time and costs, and extending the service life of the equipment.

[0056] In one embodiment, reference is made to the appendix. Figure 4 The two ends of the support shaft 10 are respectively connected to the fixing brackets. The two fixing brackets are located on both sides of the door 4, and the fixing brackets are detachably installed on the frame body 1 by bolts.

[0057] When it is necessary to install, disassemble, maintain or adjust the position of the support shaft 10, simply unscrew the bolts to remove the fixing bracket from the frame body 1, and then perform the corresponding operation on the support shaft 10.

[0058] This detachable connection method improves the flexibility and maintainability of the equipment. When the support shaft 10 is damaged or its position needs to be adjusted according to different production requirements, it can be operated quickly and easily, reducing equipment downtime and improving production efficiency.

[0059] In one embodiment, reference is made to the appendix. Figure 1 and 2 Side baffles are provided on both sides of the door 4, and the inner wall of the side baffles slides in contact with the outer wall of the aluminum rod placement groove 3.

[0060] As the aluminum rod slides down from the aluminum rod placement slot 3 through the opening door 4, the side baffles on both sides of the opening door 4 serve as guides and limiters. The inner wall of the side baffle slides in contact with the outer wall of the aluminum rod placement slot 3, ensuring the smoothness of the opening door 4 during rotation, while restricting the direction of movement of the aluminum rod, so that it can only slide down along the direction of the opening door 4.

[0061] This effectively prevents the aluminum bars from falling to the sides during the sliding process, avoiding loss of aluminum bars and damage to the equipment. The sliding contact design between the side baffle and the outer wall of the aluminum bar placement groove 3 ensures the normal rotation of the door 4, enhances the sealing between the door 4 and the aluminum bar placement groove 3, and further improves the smoothness of aluminum bar unloading.

[0062] In one embodiment, reference is made to the appendix. Figure 1 and 2 Conveyor 2 has baffles on both sides, which are mounted on the frame body 1.

[0063] During the conveyor 2's transport of aluminum bars, baffles installed on the frame body 1 are located on both sides of the conveyor 2, serving to block and guide the aluminum bars. When the aluminum bars may shift to either side during transport, the baffles will prevent them from falling and guide them to continue transporting in the predetermined direction.

[0064] This design improves the safety and reliability of aluminum bars being transported on conveyor 2, preventing safety hazards and production interruptions caused by aluminum bars falling from the sides of the conveyor. The guiding effect of the baffles allows the aluminum bars to be transported more accurately to the designated position, improving conveying efficiency and accuracy.

[0065] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily 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 is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
