Description

Technical Field

[0001] This application relates to the field of wire mesh welding technology, specifically to a material feeding and positioning device, a material feeding device, and a wire mesh welding machine. Background Technology

[0002] In the automated production process of steel mesh, the precise arrangement of longitudinal bars is the core link to ensure the welding quality of the mesh. The existing technology uses a stepless longitudinal bar mesh machine, which uses a feeding system to lower a single longitudinal bar onto a mobile platform trolley, and a magnetic platform is set on the trolley to attract and fix the longitudinal bar. Finally, the arranged longitudinal bars are transferred as a whole to the welding station for welding of the transverse bars.

[0003] However, after the longitudinal ribs fall freely from the high-level unloading bin of the feeding system, they will hit the hard surface of the magnetic platform, causing them to bounce and deviate from the preset landing position. This affects the accuracy of the longitudinal rib arrangement, making the arrangement of the longitudinal ribs not meet the processing requirements of the wire mesh machine, thus affecting production efficiency. Utility Model Content

[0004] In view of this, this application provides a material dropping and positioning device, a material dropping device, and a wire mesh welding machine to solve the problem that the longitudinal reinforcement falls off the preset dropping point, affecting the accuracy of the longitudinal reinforcement arrangement, causing the longitudinal reinforcement arrangement to fail to meet the processing requirements of the wire mesh machine, thereby affecting production efficiency.

[0005] In a first aspect, this application provides a material unloading and positioning device, disposed below the unloading hopper and corresponding to a receiving platform. The unloading hopper discharges a workpiece. The material unloading and positioning device includes a receiving component and a driving component. The receiving component includes a receiving member having a first side facing the unloading hopper, and a limiting portion provided on the first side of the receiving member. The limiting portion corresponds to the unloading hopper and is adapted to restrict the movement of the workpiece along a first direction. A driving component is connected to the receiving member and is adapted to drive the receiving member to move along a second direction to release the workpiece within the limiting portion to the receiving platform.

[0006] Beneficial effects: The receiving component is set below the feeding bin opening. After the workpiece falls from the feeding bin opening, it is received and limited by the limiting part on the receiving component. Under the action of the driving component, the receiving component moves the workpiece to the preset landing point position on the receiving platform and then releases it, avoiding the workpiece from falling directly to the receiving platform and causing collision and bouncing. This prevents the workpiece from leaving the preset landing point position, improves the accuracy of workpiece arrangement, and meets the processing requirements of the mesh machine.

[0007] Optionally, the receiving component is configured as a first receiving component, which is rotatably configured relative to the discharge hopper opening. The receiving component further includes a first support base, with the first receiving component rotatably engaged with the first support base. The fixed end of the driving component is hinged to the first support base, and the telescopic end of the driving component is hinged to the first receiving component.

[0008] Beneficial effects: The first receiving component adopts a rotating movement method in the height direction to send the received workpiece to the receiving platform, thereby preventing the workpiece from falling off the preset landing position, improving the accuracy of the longitudinal rib arrangement, and meeting the processing requirements of the mesh machine.

[0009] Optionally, the receiving component is configured as a second receiving component, which is linearly movable relative to the discharge hopper opening. The receiving component also includes a second support base, with the fixed end of the driving component fixed to the second support base and the telescopic end of the driving component fixed to the second receiving component.

[0010] Beneficial effects: The second receiving component adopts a linear movement method in the height direction to send the received workpiece to the receiving platform, thereby preventing the workpiece from falling off the preset landing position, improving the accuracy of the longitudinal rib arrangement, and meeting the processing requirements of the mesh machine.

[0011] Optionally, multiple receiving components are provided, and the multiple receiving components are arranged at intervals along the axial direction of the workpiece.

[0012] Beneficial effects: Multiple support components can support the workpiece simultaneously, improving support stability and accurately delivering the workpiece to the preset landing position.

[0013] Optionally, the receiving assembly further includes a connecting frame, with the plurality of receiving parts fixed to the connecting frame, and the connecting frame connected to the driving component.

[0014] Beneficial effects: By using a connecting frame to fix multiple receiving parts, and connecting the driving parts to the connecting frame, the number of driving parts can be reduced, and multiple receiving parts can move synchronously to accurately deliver the workpiece to the preset landing position.

[0015] Optionally, the limiting part is configured as a V-groove formed on the first side of the receiving member.

[0016] Beneficial effects: The limiting part adopts a V-groove structure, which makes it easy for the workpiece to fall into the V-groove, and also makes the limiting part suitable for limiting workpieces of different diameters. In addition, it also makes it easy for the workpiece to be released from the limiting part onto the receiving platform.

[0017] Optionally, when the limiting part is in the position of releasing the workpiece to the receiving platform, the workpiece is provided on the front side of the receiving member along the moving direction of the receiving platform, and the workpiece is not provided on the rear side of the receiving member.

[0018] Beneficial effects: The receiving component moves the workpiece and releases the workpiece in the limiting part to the receiving platform. When the receiving platform moves in the moving direction, the receiving component does not obstruct the workpiece on the receiving platform, ensuring the normal movement of the receiving platform.

[0021] Optionally, the material feeding device includes a longitudinal rib feeding frame, and the receiving component and the driving component are both mounted on the longitudinal rib feeding frame.

[0022] Beneficial effect: By mounting both the receiving components and the driving components on the longitudinal rib blanking frame, the overall structure becomes compact.

[0023] Thirdly, this application provides a wire mesh welding machine, including the material feeding device described in any one of the above-mentioned methods.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Please refer to Figures 1-5 In a first aspect, embodiments of this application provide a material unloading and positioning device, disposed below a material unloading hopper 100 and corresponding to a receiving platform 200. A workpiece 300 is discharged from the material unloading hopper 100. The material unloading and positioning device includes a receiving component 1 and a driving component 2. The receiving component 1 includes a receiving member having a first side facing the material unloading hopper 100. A limiting portion 12 is provided on the first side of the receiving member, corresponding to the material unloading hopper 100, and adapted to restrict the workpiece 300 from moving along a first direction. The driving component 2 is connected to the receiving member and adapted to drive the receiving member to move along a second direction, thereby releasing the workpiece 300 within the limiting portion 12 to the receiving platform 200.

[0037] Specifically, refer to Figure 1 , Figure 2 , Figure 3The workpiece 300 has longitudinal ribs. A limiting part 12 is provided on the first side of the receiving part facing the unloading hopper 100. When the workpiece 300 is discharged from the unloading hopper 100, the workpiece 300 falls into the limiting part 12 of the receiving part after leaving the unloading hopper 100. The workpiece 300 is restricted by the limiting part 12 to move in the first direction. Then the driving part 2 works to drive the receiving part to move relative to the unloading hopper 100. The receiving part drives the workpiece 300 on it to move. When the workpiece 300 moves to the receiving platform 200, the workpiece 300 is released, so that the workpiece 300 is in the preset landing position.

[0038] It should be noted that the first direction mentioned above refers to a direction roughly parallel to the extension direction of the receiving component. That is, when the workpiece 300 is located within the limiting part 12, when the driving part 2 drives the receiving component to move, the workpiece 300 cannot detach from the limiting part 12, preventing relative displacement between the workpiece 300 and the receiving component, thus ensuring that the workpiece 300 is delivered to the preset landing position. The second direction mentioned above refers to the height direction. That is, when the driving part 2 drives the receiving component to move, the receiving component moves in the height direction, thereby moving the workpiece 300 on the receiving component from a higher position to a lower position, thus preventing the workpiece 300 from freely falling onto the receiving platform 200.

[0039] It should be noted that, referring to Figure 3 The aforementioned discharge hopper 100 is a conventional structure of the material discharge device. The receiving platform 200 can be optionally configured as a magnetic suction platform. A mobile trolley is provided below the magnetic suction platform, which can drive the magnetic suction platform to move.

[0040] In this embodiment, with the cooperation of the driving component 2, the receiving component and the limiting part 12, the receiving component can drive the workpiece 300 to the preset landing position on the receiving platform 200 and then release it, so as to prevent the workpiece 300 from falling directly to the receiving platform 200 and causing collision and bouncing, thereby preventing the workpiece 300 from leaving the preset landing position, improving the arrangement accuracy of the workpiece 300 and meeting the processing requirements of the mesh machine.

[0041] Optionally, refer to Figure 2 , Figure 3 , Figure 4 The receiving component is configured as a first receiving component 11, which is rotatably configured relative to the discharge port 100. The receiving component 1 also includes a first support base 13, with the first receiving component 11 and the first support base 13 rotatably engaged. The fixed end of the driving component 2 is hinged to the first support base 13, and the telescopic end of the driving component 2 is hinged to the first receiving component 11.

[0042] Specifically, the receiving member can be configured as a first receiving member 11, and the first support base 13 is used to support the first receiving member 11 and the driving member 2. When the telescopic end of the driving member 2 is working, the telescopic end of the driving member 2 can drive the first receiving member 11 to rotate relative to the first support base 13. The limiting part 12 is disposed on the first receiving member 11, and the rotation of the first receiving member 11 causes the limiting part 12 to change its position in height.

[0043] When the first receiving component 11 receives the workpiece 300 falling from the unloading hopper 100, the limiting part 12 on the first receiving component 11 is in a high position and close to the unloading hopper 100. After the workpiece 300 falls to the limiting part 12, the driving component 2 works to drive the first receiving component 11 to rotate, so that the workpiece 300 moves from the high position to the low position. When the limiting part 12 moves to below the receiving platform 200, the workpiece 300 on the limiting part 12 is received and fixed by the receiving platform 200, so that the limiting part 12 is separated from the workpiece 300, and the receiving and transfer of the workpiece 300 is completed.

[0044] With this configuration, the first receiving component 11 moves by rotating in the height direction to deliver the received workpiece 300 to the receiving platform 200, thereby preventing the workpiece 300 from falling directly onto the receiving platform 200 and causing collision and bouncing. This also prevents the workpiece 300 from leaving the preset landing position, improves the accuracy of the longitudinal rib arrangement, and meets the processing requirements of the mesh machine.

[0045] In one specific implementation, refer to Figure 4 The first receiving component 11 includes a first plate segment 111 and a second plate segment 112 connected to each other. The first plate segment 111 and the second plate segment 112 are arranged perpendicularly to each other. The first plate segment 111 and the first support base 13 are rotatably engaged. The telescopic end of the driving component 2 is connected to the first plate segment 111 in a transmission manner. The limiting part 12 is provided on the second plate segment 112. In this way, by the movement of the telescopic end of the driving component 2, the first plate segment 111 can be rotated relative to the first support base 13, which in turn drives the second plate segment 112 to rotate, thereby changing the height of the limiting part 12 on the second plate segment 112 and completing the receiving and transfer of the workpiece 300.

[0046] Of course, in addition to the above-mentioned configuration, the first receiving part 11 can also adopt other structures. The core function of the first receiving part 11 is to enable the first receiving part 11 to rotate under the action of the driving part 2 and to drive the limiting part 12 to change its position in height.

[0047] Optionally, refer to Figure 5 The receiving component is configured as a second receiving component 15, which is linearly movable relative to the discharge port 100. The receiving component 1 also includes a second support base 14, the fixed end of the driving component 2 is fixed to the second support base 14, and the telescopic end of the driving component 2 is fixed to the second receiving component 15.

[0048] Specifically, in addition to being configured as the first receiving member 11, the receiving member can also be configured as the second receiving member 15. The second support base 14 is used to support the driving member 2. When the telescopic end of the driving member 2 is working, the telescopic end of the driving member 2 can drive the first receiving member 11 to move linearly up and down relative to the first support base 13. The limiting part 12 is disposed on the second receiving member 15. The up and down movement of the second receiving member 15 changes the position of the limiting part 12 in terms of height.

[0049] When receiving the workpiece 300 falling from the unloading hopper 100, the limiting part 12 on the second receiving part 15 is in a high position and close to the unloading hopper 100. After the workpiece 300 falls to the limiting part 12, the driving part 2 works to drive the first receiving part 11 to descend, so that the workpiece 300 moves from a high position to a low position. When the limiting part 12 moves to below the receiving platform 200, the workpiece 300 on the limiting part 12 is received and fixed by the receiving platform 200, so that the limiting part 12 is separated from the workpiece 300, and the receiving and transfer of the workpiece 300 is completed.

[0050] With this configuration, the second receiving component 15 moves in a straight line in the height direction to deliver the received workpiece 300 to the receiving platform 200, thereby preventing the workpiece 300 from falling directly to the receiving platform 200 and causing collision and bouncing. This also prevents the workpiece 300 from deviating from the preset landing point, improves the accuracy of the longitudinal rib arrangement, and meets the processing requirements of the mesh machine.

[0051] In one specific implementation, refer to Figure 5 The second receiving component 15 includes a third plate segment 151 and a fourth plate segment 152 connected to each other. The third plate segment 151 and the fourth plate segment 152 are arranged perpendicularly to each other. The third plate segment 151 is connected to the telescopic end of the driving component 2, and the limiting part 12 is provided on the fourth plate segment 152. In this way, by the movement of the telescopic end of the driving component 2, the third plate segment 151 can be driven to descend in the height direction, which in turn drives the fourth plate segment 152 to descend in the height direction, thereby changing the height of the limiting part 12 on the second plate segment 152 and completing the receiving and transfer of the workpiece 300.

[0052] Of course, in addition to the above-mentioned configuration, the second receiving part 15 can also adopt other structures. The core function of the second receiving part 15 is to enable the second receiving part 15 to move up and down in a straight line under the action of the driving part 2, and to drive the limiting part 12 to change its position in height.

[0053] Optionally, regardless of whether the receiving part is set as the first receiving part 11 or the second receiving part 15, the driving part 2 can be set as one of the following: telescopic cylinder, telescopic electric cylinder, telescopic hydraulic cylinder or screw nut drive motor assembly.

[0054] Optionally, refer to Figure 4 There are multiple receiving components, which are arranged at intervals along the axial direction of the workpiece 300.

[0055] Specifically, multiple support members are arranged along the axial direction of the workpiece 300, i.e. the length direction of the longitudinal rib. The support member can be a first support member 11 or a second support member 15. The multiple support members work together to support the longitudinal rib, and the limiting part 12 on each support member works together to limit the longitudinal rib. The arrangement of multiple support members can improve the stability of the support for the longitudinal rib and accurately deliver the workpiece 300 to the preset landing position.

[0056] Optionally, the receiving component 1 also includes a connecting frame, with multiple receiving parts fixed to the connecting frame, and the connecting frame connected to the driving component 2.

[0057] With this setup, multiple receiving components are fixed by a connecting frame, and the driving component 2 is connected to the connecting frame. This reduces the number of driving components 2 required and facilitates the synchronous movement of multiple receiving components, accurately delivering the workpiece 300 to the preset landing position.

[0058] In one specific implementation, refer to Figure 4 Taking the first receiving component 11 as an example, the connecting frame is set as the first connecting frame 3. The first connecting frame 3 is a U-shaped frame structure. Multiple first support seats 13 are set. The first support seats 13 are respectively set on both sides and the top of the first connecting frame 3.

[0059] The first connecting frame 3 includes a horizontal plate 31 and folded edges 32 fixed at both ends of the horizontal plate 31. Each of the two folded edges 32 is provided with a first receiving member 11, and the first plate segment 111 of the folded edge 32 and the first receiving member 11 are fixed together. The two first receiving members 11 are rotatably engaged with the first support seats 13 on both sides. The fixed end of the driving member 2 is hinged to the first support seat 13 located above, and the telescopic end of the driving member 2 is hinged to the end face of the horizontal plate 31 away from the folded edge 32.

[0060] By adopting the above configuration, multiple first receiving parts 11 are installed on the first connecting frame 3, and the first connecting frame 3 is moved by a driving part 2, thereby moving multiple first receiving parts 11 in the height direction.

[0061] In another specific implementation, refer to Figure 5 Taking the second receiving component 15 as an example, the connecting frame is set as the second connecting frame 4. The second connecting frame 4 is connected to the telescopic end of the driving component 2, and multiple second receiving components 15 are installed on the second connecting frame 4. This configuration can also drive the second connecting frame 4 to move through one driving component 2, thereby driving multiple second receiving components 15 to move in the height direction.

[0062] Optionally, refer to Figure 4 , Figure 5 The limiting part 12 is configured as a V-shaped groove opened on the first side of the receiving part.

[0063] Specifically, when the receiving component is set as the first receiving component 11, the V-groove is formed on the second plate segment 112. When the receiving component is set as the second receiving component 15, the V-groove is formed on the fourth plate segment 152.

[0064] With this configuration, the limiting part 12 adopts a V-groove structure, which on the one hand facilitates the workpiece 300 to fall into the V-groove, and on the other hand makes the limiting part 12 suitable for limiting workpieces 300 of different diameters. In addition, it also facilitates the release of the workpiece 300 from the limiting part 12 onto the receiving platform 200.

[0065] Of course, in addition to the V-groove structure mentioned above, the limiting part 12 can also be other structures or devices that can restrict the movement of the workpiece 300 relative to the receiving part.

[0066] Optionally, refer to Figure 3 When the limiting part 12 is in the position of releasing the workpiece 300 to the receiving platform 200, the workpiece 300 is provided on the front side of the receiving part along the moving direction of the receiving platform 200, and the workpiece 300 is not provided on the rear side of the receiving part.

[0067] Specifically, when the receiving component moves the limiting part 12 downward and the workpiece 300 comes into contact with the receiving platform 200, due to the structure of the receiving component, a part of the receiving component is located below the receiving platform 200 or at the same horizontal plane as the receiving platform 200. When the receiving platform 200 moves subsequently, in order to avoid the position of the receiving component affecting the workpiece 300 that has been arranged on the receiving platform 200, the front side of the receiving component is limited to having a workpiece 300, and the rear side of the receiving component is not provided with a workpiece 300.

[0068] With this configuration, the receiving component moves the workpiece 300 and releases the workpiece 300 in the limiting part 12 to the receiving platform 200. When the receiving platform 200 moves in the moving direction, the receiving component does not obstruct the workpiece 300 on the receiving platform 200, thus ensuring the normal movement of the receiving platform 200.

[0069] In one specific embodiment, the discharge port 100 has a first side facing the moving direction of the receiving platform 200 and a second side facing away from it. When the receiving member is set as a first receiving member 11, the first receiving member 11 is located on the second side of the discharge port 100. In this way, there is no workpiece 300 behind the first receiving member 11, ensuring the normal movement of the receiving platform 200.

[0070] In another specific embodiment, when the receiving member is configured as the second receiving member 15, the fourth plate segment 152 is disposed on the side of the third plate segment 151 facing the moving direction of the receiving platform 200. This ensures that there is no workpiece 300 behind the second receiving member 15, guaranteeing the normal movement of the receiving platform 200.

[0071] Secondly, this application provides a material unloading device, including the material unloading positioning device described above.

[0072] In this embodiment, the material feeding device has the aforementioned material feeding positioning device, which improves the material feeding accuracy of the material feeding device and meets production requirements.

[0073] Optionally, the material feeding device includes a longitudinal rib feeding frame 400, on which the receiving component 1 and the driving component 2 are both mounted.

[0074] Specifically, the receiving component is selected as either the first receiving component 11 or the second receiving component 15 according to actual needs. When the receiving component is set as the first receiving component 11, the first support seat 13 is installed on the longitudinal rib blanking rack 400. When the receiving component is set as the second receiving component 15, the second support seat 14 is installed on the longitudinal rib blanking rack 400. Of course, in some cases, the first support seat 13 and the second support seat 14 can be removed, and the first receiving component 11 or the second receiving component 15 can be directly installed on the longitudinal rib blanking rack 400.

[0075] With this configuration, both the receiving component 1 and the driving component 2 are installed on the longitudinal rib blanking rack 400, making the overall structure compact.

[0076] Thirdly, this application provides a wire mesh welding machine, including the material feeding device of any one of the above.

[0077] In this embodiment, the wire mesh welding machine has the above-mentioned unloading device, which enables the workpieces 300 to be precisely arranged during the unloading process, thereby improving the processing quality and efficiency of the wire mesh machine.

[0078] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
