Description

Technical Field

[0001] The utility model relates to the technical field of band sawing machines, in particular to an automatic feeding device for band sawing machines. Background Art

[0002] A band saw is a tool used to cut wood, metal or other materials. It achieves cutting by rotating a band saw blade. Band saws are commonly used in industrial production and can perform precise cutting work efficiently. They have a fast cutting speed and a smooth cutting surface and are suitable for materials of various shapes and sizes.

[0003] Band saw is a widely used cutting device, which is mainly used for cutting materials with long lengths. A loading device is needed for loading. For example, Chinese patent CN217166783U discloses a loading device for a band saw, which is provided with a lifting mechanism to lower the height of the upper end of the transport mechanism, so that workers can place bars on the transport mechanism, and start the lifting mechanism again to raise the height of the upper end of the transport mechanism so that the upper end of the transport mechanism is consistent with the height of the storage rack, thereby completing the loading and improving work efficiency; starting the driving mechanism, the driving mechanism drives the transport mechanism to approach the saw body, thereby transporting the bars to the storage rack, reducing the time of manual handling and improving work efficiency. However, when the device loads multiple bars, most of the bars are cylindrical, and the bars on the transport mechanism cannot be limited. The bars are easy to fall during transportation, which poses a safety hazard. Therefore, we propose an automatic loading device for a band saw. Utility Model Content

[0004] The utility model aims to provide an automatic feeding device for a band sawing machine, which has the effect of limiting the position of the bar material during the feeding process to prevent the bar material from falling during the feeding process.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an automatic loading device for a band saw, comprising a frame, a sawing machine body installed on the frame, and a loading rack fitted with the side of the frame, the loading rack consisting of a mounting frame and a transfer rack, a universal wheel is installed at the bottom of the mounting frame, the transfer rack is installed on the mounting frame through a telescopic assembly, a material transport assembly is installed on the transfer rack, a limiting assembly clamped on the outside of the material transport assembly is installed on the transfer rack, and a driving assembly for changing the blocking range of the limiting assembly is also provided on the transfer rack.

[0006] By adopting the above technical solution, the transfer frame is adjusted in height at the bottom of the mounting frame through the telescopic component. The rods to be processed are placed on the transfer frame and then the height is adjusted to be flush with the frame. Then the material transport component is started to drive the rods on the transfer frame toward the sawing machine body. During the material transport process of the material transport component, the limiting component blocks the rods to prevent them from falling. The driving component is started to change the blocking range of the limiting component. The blocking range can be changed according to the volume of the transported rods, which has higher applicability.

[0007] The utility model is further configured as follows: the telescopic assembly includes a mounting sleeve rod installed on the mounting frame, a connecting support rod movably installed in the mounting sleeve rod and having one end connected to the bottom of the transfer frame, and a hydraulic rod installed on the mounting sleeve rod.

[0008] The utility model is further configured as follows: the output end of the hydraulic rod is fixedly connected to the transfer frame.

[0009] By adopting the above technical solution, the hydraulic rod starts to push the transfer frame up and down on the top of the installation frame, changing the horizontal height of the transfer frame, making it convenient to align with the frame after the bars to be processed are installed, reducing the fatigue of manual handling. The transfer frame is movable up and down, and the connecting support rod moves up and down in the installation sleeve rod, making the transfer frame more stable.

[0010] The utility model is further configured as follows: the material transport assembly includes a plurality of transport rollers rotatably connected to the inner side of the transport frame and a transport motor installed on the transport frame.

[0011] The utility model is further configured as follows: the transfer rollers are distributed on the transfer frame at equal distances in the transverse direction, and the output shaft of the transfer motor is fixedly connected to the leftmost transfer roller.

[0012] By adopting the above technical solution, the transfer motor starts to drive the leftmost transfer roller to rotate. The leftmost transfer roller serves as a driving force, so that the bar material continuously approaches the sawing machine body on the other several transfer rollers, thereby completing the sawing of the bar material.

[0013] The utility model is further configured as follows: the limiting component includes two limiting transverse plates movable forward and backward inside the transfer frame, a limiting groove opened on the limiting transverse plates and adapted to the transfer roller, and a limiting block installed in the limiting groove.

[0014] By adopting the above technical solution, when the limiting cross plate moves back and forth inside the transfer frame, it is stuck on the outer side of the transfer roller through the limiting groove, thereby limiting the rods transferred on the transfer roller and preventing the rods from falling.

[0015] The utility model is further configured as follows: the limiting component further comprises a connecting vertical groove and an annular groove provided on the transfer roller, and a plurality of the annular grooves are provided and communicated with the connecting vertical grooves.

[0016] The utility model is further configured as follows: the bottom of the limiting block extends into the connecting vertical groove, and the distance between the left and right sides of the inner wall of the connecting vertical groove is equal to the distance between the front and rear sides of the inner wall of the annular groove.

[0017] By adopting the above technical solution, when the limiting block is in the connecting vertical groove, the driving component starts to change the distance between the two limiting transverse plates. After the distance is adjusted, the limiting block can rotate in the annular groove, which does not affect the rotation of the transfer roller and strengthens the connection between the limiting transverse plate and the transfer roller, thereby improving the blocking effect on the bar material.

[0018] The utility model is further configured as follows: the driving assembly includes a driving motor installed on the transfer frame, a bidirectional screw rotatably connected to the inner side of the transfer frame and fixedly connected to the output shaft of the driving motor, and two guide sliders threadedly connected to the outside of the bidirectional screw.

[0019] The utility model is further configured as follows: the guide sliding block is fixedly connected to the limiting transverse plate, and the highest point of the bidirectional screw and the highest point of the transfer roller are vertically displaced.

[0020] By adopting the above technical solution, the driving motor starts to drive the bidirectional screw to rotate. When the bidirectional screw rotates, the two guide sliders drive the two limiting cross plates to move closer to or away from each other, and the distance between the two limiting cross plates is changed. The blocking range can be changed according to the volume of the transported rods, and the applicability is higher. The bidirectional screw and the transfer roller are staggered up and down, so that the bidirectional screw will not contact the rods on the transfer roller when rotating, and will not affect the transportation of the rods.

[0021] The beneficial effects of the utility model are as follows: the transfer frame adjusts its height at the bottom of the mounting frame through the telescopic assembly, and after the bar to be processed is placed on the transfer frame, the height is adjusted to be flush with the frame, and then the material transport assembly is started to drive the bar on the transfer frame toward the sawing machine body. During the material transporting process of the material transporting assembly, the limiting assembly blocks the bar to prevent it from falling, and the driving assembly is started to change the blocking range of the limiting assembly. The blocking range can be changed according to the volume of the transported bar, and the applicability is higher. BRIEF DESCRIPTION OF THE DRAWINGS
