Description

Technical Field

[0001] This utility model relates to the field of sawing technology, specifically a sawing machine with an auxiliary unloading device. Background Technology

[0002] A band saw is a saw with a saw blade tensioned and mounted on two saw wheels, which drive the saw blade to cut. There are two types of band saws: vertical and horizontal.

[0003] A patent search revealed a document titled "Saw with Auxiliary Material Discharge Device" (publication number "CN220698403U"). This document describes a device that clamps the material using pressure rollers, but the clamping state is limited by springs, meaning the rollers can only provide a soft clamping. During cutting, the moving saw blade causes vibrations in the material. While the operator can hold the uncut area to position the material, this method easily leads to significant dimensional errors, affecting the precision of material processing. Therefore, this invention designs a saw with an auxiliary material discharge device to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a saw with an auxiliary unloading device to solve the problems mentioned in the background art.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, a saw with an auxiliary unloading device includes a saw 1, a saw blade 2, and a controller 3. First electric push rods 4 are fixed on the left and right sides inside the saw 1. A clamping plate 5 is fixed on the output end of the first electric push rods 4. A frame 6 is fixed on the rear end of the saw 1. A discharge assembly 7 is provided inside the saw 1. The discharge assembly 7 includes a first motor 701 fixed on the middle side of the rear end inside the saw 1. A rotating sleeve 702 is fixed on the rear end of the first motor 701. A placement groove 703 is integrally provided inside the rotating sleeve 702. There are three placement grooves 703. The angle between each pair of placement grooves 703 is 120 degrees. A discharge hole 704 is integrally provided on the lower left side inside the frame 6. A guide plate 705 is fixed inside the discharge hole 704. A box 706 is provided on the left side of the frame 6.

[0025] The first motor 701 is a stepper motor with a self-locking function. The first motor 701 stops running after rotating 120 degrees. The first motor 701 and the first electric push rod 4 are connected to the controller 3 through wires. The operator first places the round bar at the lower end of the saw blade 2, so that the cutting area of ​​the round bar coincides with the saw blade 2. At this time, the front end of the cutting area of ​​the round bar is positioned between two clamping plates 5, while the rear end of the cutting area of ​​the round bar is in the placement groove 703 at the top of the rotating sleeve 702. The operator then activates the first electric push rod 4, which pushes the clamping plates 5 to clamp and fix the front end of the round bar. The operator then uses the sawing machine 1 to move the running saw blade 2 along the direction of the round bar to cut it. After cutting, the operator activates the first motor 701, which drives the rotating sleeve 702 to rotate 180 degrees counterclockwise and then stops. At this time, the cut round bar falls into the box 706 through the discharge hole 704 and is guided by the guide plate 705. Example 2

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a second electric push rod 8 is fixedly installed at the top center of the frame 6, and a special-shaped rod 9 is fixedly installed at the bottom of the second electric push rod 8. The special-shaped rod 9 slides through the frame 6. The cross-section of the special-shaped rod 9 is designed in a Y-shape. The second electric push rod 8 is connected to the controller 3 through a wire. A pressure plate 10 is fixedly installed at the bottom of the special-shaped rod 9. A rotating shaft 11 is rotatably connected to the front and rear ends inside the pressure plate 10. A pulley 12 is fixedly sleeved on the outside of the rotating shaft 11. A toothed belt 13 is tightly fitted on the outside of the pulley 12 and meshes with its teeth. The toothed belt 13 is sleeved on the outside of the pressure plate 10. The front left side of the pressure plate 10 is... A second motor 14 is fixedly installed. The second motor 14 has a self-locking function. The output end of the second motor 14 is fixedly connected to the rotating shaft 11 at the front end. Infrared beam sensors 15 are fixedly installed on the upper left and right sides inside the frame 6. The infrared beam sensors 15 are connected to the controller 3 through wires. The infrared beam sensors 15 and the rotating sleeve 702 are offset from each other. Support rods 16 are fixedly installed on the front and rear sides at the bottom inside the frame 6. An arc plate 17 is fixedly installed on the top of the support rod 16. The inner wall of the arc plate 17 fits against the outer wall of the rotating sleeve 702. The center of the arc plate 17 is concentric with the center of the rotating sleeve 702.

[0027] According to the operation method in Embodiment 1, when the clamping plate 5 clamps the front end of the round bar, the operator can activate the second electric push rod 8. This causes the second electric push rod 8 to control the shaped rod 9 to drive the pressure plate 10, along with the toothed belt 13, to clamp and fix the rear end of the round bar. In this way, the positions of the beginning and end of the round bar cutting area are fixed, ensuring the stability of the round bar during subsequent cutting. After the round bar is cut, the operator first activates the second motor 14. The second motor 14 drives the rotating shaft 11 to rotate the pulley 12 in conjunction with the toothed belt 13. At this time, the rotating toothed belt 13 pushes the cut round bar along... The second motor 14 moves backward in the direction of the placement slot 703 until the infrared beam sensor 15 no longer detects the round bar. In this way, the cut round bar is moved into the frame 6 to prevent it from colliding with the saw 1 when it is dropped. The operator then resets the first electric push rod 4 and the second electric push rod 8 by using the controller 3, which eliminates the clamping state of the clamping plate 5 and the pressure plate 10 on the round bar. Then, by using the first motor 701, the dropping operation of the round bar can be realized. In addition, the arc plate 17 supports the rotating sleeve 702 to ensure the stability of the rotating sleeve 702 when it rotates.
