Technical Field

[0001] This utility model relates to the field of sawing technology, and more specifically, to a bar blanking detection device. Background Technology

[0002] Bar sawing is typically done using a sawing machine. After sawing, the bars are unloaded from the saw, and then their weight and length need to be measured, and they are marked with information onto the surface of the bars. Traditional methods require multiple machines, reducing efficiency and increasing equipment costs. Chinese patent application number 2021116031758 discloses an automatic metal tube / bar unloading mechanism, adaptable to various lengths of metal tubes / bars, integrating material feeding, laying, and distribution into one unit; during material collection, it can not only gather metal tubes / bars together but also stack them in an aligned manner. However, it cannot perform bar measurement and marking operations; the measurement and marking of bar weight and length still require multiple machines, reducing efficiency and increasing equipment costs. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a bar blanking detection device, which can measure the weight and length of the bar and mark it.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a bar feeding detection device, including a frame, a loading frame installed on the frame, a weighing sensor installed between the loading frame and the frame, a loading groove provided on the loading frame, the bar being loaded in the loading groove, a laser marking machine installed on the frame, the laser marking machine emitting a laser towards the surface of the bar for marking, and a distance sensor installed on the loading frame, the distance sensor detecting the distance between itself and the end of the bar.

[0005] After the bar stock is cut on the saw, it is transferred to the unloading device, where the loading frame supports the bar stock. The bar stock is loaded stably and reliably in the loading slot, and the weight of the bar stock is measured by a weighing sensor. A distance sensor detects the distance between itself and the end of the bar stock, thereby calculating the length of the bar stock. A laser marking machine emits a laser beam towards the surface of the bar stock to mark various information onto the surface. The bar stock unloading and detection device of this patent application can measure the weight and length of the bar stock, and mark the bar stock information onto the surface of the bar stock using a laser marking machine. A single device realizes multiple operation actions, which helps to improve work efficiency and reduce equipment investment.

[0006] Preferably, the loading slot has a V-shaped structure.

[0007] The V-shaped loading groove serves to position the bar stock, ensuring the accuracy and reliability of the loading position.

[0008] Preferably, distance sensors are installed at both ends of the loading frame, with the two distance sensors facing the two ends of the bar respectively.

[0009] The length of the rod is calculated by measuring the distance to both ends of the rod using two distance sensors, making the measurement operation convenient.

[0010] Preferably, a mounting base is provided at the bottom of the loading frame, and a positioning groove is provided on the mounting base. The mounting base is connected to a transverse limit plate. A connecting base is installed on the frame, and a load cell is installed on the connecting base. The weighing end of the load cell is placed in the positioning groove and supported on the mounting base. The transverse limit plate is abutted against the side of the connecting base.

[0011] The lateral movement limit plate restricts the lateral movement of the loading frame. The weighing end of the load cell is placed in the positioning slot, which restricts the longitudinal movement of the loading frame and ensures stable support of the bar stock by the loading frame.

[0012] Preferably, the frame includes a frame body and a side panel, with the side panel connected to the perimeter of the frame body. The side panel surrounds the loading frame to limit the lateral and longitudinal movement of the loading frame.

[0013] The surrounding panels limit the lateral and longitudinal movement of the loading frame, further ensuring its stability.

[0014] Preferably, the frame includes several pillars and a support frame. The support frame includes crossbeams and longitudinal beams, which are connected together to form a frame structure. The pillars are fastened to the support frame, and the loading frame is supported on the support frame.

[0015] The support frame supports the entire loading frame, and the uprights support the support frame, thus ensuring the stability of the frame and the loading frame.

[0016] Preferably, the loading rack includes a base plate and several upright plates, which are connected to the base plate at intervals. The upright plates are connected to flat plates and inclined plates to form a loading groove.

[0017] The loading rack is lightweight, has good structural strength, and strong load-bearing capacity.

[0018] Preferably, both ends of the loading frame are fastened with U-shaped protective plates, with the openings of the two protective plates facing each other.

[0019] Protective plates are installed at both ends of the loading frame to protect the bars and prevent them from slipping off the loading frame.

[0020] Preferably, a buffer plate is installed on the loading frame, a buffer spring is installed between the buffer plate and the loading frame, and a clearance groove is provided on the loading frame, through which the buffer plate passes and protrudes from the upper surface of the loading frame.

[0021] When the bars are loaded onto the loading rack, they first come into contact with the buffer plate, which provides support and cushions the bars, preventing damage from impacts during their descent. The bars are then supported on the bottom of the loading trough, facilitating subsequent measurement and marking.

[0022] Preferably, a lifting seat is installed on the frame, a lifting slide rail is provided on the lifting seat, a linear slide is fastened to the laser marking machine, the linear slide is slidably connected to the lifting slide rail, a lifting screw is installed on the lifting seat, a lifting block is fastened to the laser marking machine, the lifting block is threadedly connected to the lifting screw, and the rotation of the lifting screw drives the laser marking machine to move up and down.

[0023] Rotating the lifting screw allows the laser marking machine to move up and down, thus adjusting the laser marking height to accommodate marking operations on different bar materials. During the lifting and moving motion, the linear slide moves along the lifting rail, ensuring the smoothness and precision of the laser marking machine's movement.

[0024] Compared with the prior art, the beneficial effects of this utility model are: (1) The bar material feeding detection device can measure the weight and length of the bar material, and mark the bar material information on the surface of the bar material by laser marking machine. A single device realizes multiple operation actions, which is conducive to improving work efficiency and reducing equipment investment; (2) When the bar material is loaded onto the loading frame, it can buffer and absorb energy to prevent the bar material from being damaged by collision during the falling process.

A support 33 is mounted on loading frame 2, and the distance sensors 32 are mounted on the support 33. U-shaped protective plates 40 are fastened to both ends of loading frame 2, with the openings of the two protective plates 40 facing each other. Windows 41 are provided on the protective plates 40, and the two distance sensors 32 are positioned facing the windows 41, through which the laser beam emitted by the laser marking machine 31 passes.

[0056] A lifting seat 34 is installed on the frame 1, and a lifting slide rail 35 is provided on the lifting seat 34. A linear slide 36 is fastened to the laser marking machine 31. The linear slide 36 is slidably connected to the lifting slide rail 35. A lifting screw 37 is installed on the lifting seat 34. A rotating handle 38 is connected to the upper end of the lifting screw 37. A lifting block 39 is fastened to the laser marking machine 31. The lifting block 39 is threadedly connected to the lifting screw 37. The rotation of the lifting screw 37 drives the laser marking machine 31 to move up and down.

[0057] Rotating the lifting screw 37 enables the laser marking machine 31 to move up and down, thereby adjusting the laser marking height to accommodate marking operations on different bar materials. During the lifting and lowering movement of the laser marking machine 31, the linear slide 36 moves along the lifting rail 35, ensuring the stability and precision of the laser marking machine 31's movement.

[0058] After the bar stock is cut on the saw, it is transferred to the unloading device, where the loading frame 2 supports it. The bar stock is loaded stably and reliably in the loading slot 18, and its weight is measured by the weighing sensor 13. The distance sensor 32 detects the distance between itself and the end of the bar stock, thereby calculating the length of the bar stock. The laser marking machine 31 emits a laser beam towards the surface of the bar stock to mark various information onto its surface. The bar stock unloading and detection device of this patent application can measure the weight and length of the bar stock, and mark the bar stock information onto its surface using the laser marking machine 31. A single device performs multiple operations, which helps to improve work efficiency and reduce equipment investment.

[0059] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
