Description

Technical Field

[0001] This utility model relates to the technical field of belt cutting equipment, specifically a belt cutting machine. Background Technology

[0002] With the in-depth implementation of lean management throughout the mine, waste conveyor belt strips began to be used underground to replace single-column protective ropes. Due to the huge demand, the initial cutting was done manually with a paper cutter, which was not only time-consuming and labor-intensive, but also posed a safety risk of hand cuts. Subsequently, the process was improved, a special mold was made, and the belt was cut by pulling a tractor. The speed and tension of the tractor-pulled cutting method were difficult to keep constant, which easily led to the belt strips being of different widths and with uneven edges. Such products with unstable quality would have their protective performance and durability greatly reduced in actual use, and would not achieve the expected safety effect. Utility Model Content

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-4This utility model provides an embodiment of a belt cutting machine, including a placement platform 1, pressure rollers 3, adjusting devices 4, and a cutting frame 5. A drive unit is located on either side of the placement platform 1, and the output end of the drive unit is connected to a drive roller. The drive roller and the pressure roller 3 together transport the belt. Gears 8 and chains 9 form a synchronous transmission system, ensuring that the two drive rollers rotate completely synchronously and at the same speed in opposite directions. The chain drive has a precise transmission ratio and strong load-bearing capacity, ensuring the synchronization and stability of the traction force. A gear 8 is located at the input end of the drive roller, and the gears 8 on the two drive rollers are connected by chains 9. Pressure rollers 3 are spaced apart on the drive rollers, pressing the belt tightly against them from above. Friction prevents the belt from slipping during traction and cutting. Together with the drive rollers, this forms a reliable clamping mechanism, ensuring the stability of the belt feed during cutting. Adjusting devices 4 are respectively located on the two shaft ends of the pressure roller 3. The adjusting device 4 includes a fixed frame 401, a lead screw 402, and a slider 403. The fixed frame 401 is bolted to a connecting frame at the top of the drive roller. The fixed frame 401 is U-shaped, with a through hole on its lateral end. The lead screw 402 passes through the through hole, and its bottom end abuts against the fixed frame 401. A slider 403 is mounted on the lead screw 402. The slider 403 has an internal threaded hole that mates with the lead screw 402. Either end of the slider 403 is connected to the shaft end of the pressure roller 3. By rotating the lead screw 402, the slider 403 is driven to move up and down, thereby precisely adjusting the gap between the pressure roller 3 and the drive roller to accommodate belts of different thicknesses. A cutting frame 5 is provided between the two pressure rollers 3. The cutting frame 5 consists of an arc-shaped guide frame 501 and a blade box 502. The horizontal end of the arc-shaped guide frame 501 is connected to the support platform, and its arc-shaped surface fits against the inner surface of the belt, providing support at the cutting point. Its arc-shaped end contacts the bottom end of the belt. Blade boxes 502 are spaced at the top of the arc-shaped guide frame 501. Several cutting grooves are equally spaced on the blade box 502. The support platform has positioning grooves corresponding to the positions of the cutting grooves. Blades are installed in the cutting grooves and cut along the belt running direction. The blades are made of alloy steel. A removable cover plate is provided on the blade box 502 to facilitate the installation and removal of the blades located in the blade box 502, realizing modular and standardized installation of the blades. The cover plate design makes the replacement, cleaning and maintenance of the blades extremely convenient, greatly reducing the post-processing costs. To reduce maintenance costs and time, the blade extends downwards and inserts into the positioning groove. The cutting groove is used to fix the blade angle, and the positioning groove on the support platform is used to receive the bottom end of the blade, effectively preventing the blade from shaking, chipping, or breaking during cutting, greatly improving cutting quality and extending blade life. The contact ends of the lead screw 402 and the fixed frame 401 are equipped with bearing seats. The drive unit includes a drive motor 6 and a reducer 7. The output end of the drive motor 6 is connected to the input end of the reducer 7 through a transmission belt. The input end of the reducer 7 is coaxially connected to the gear 8 at the input end of any one of the drive rollers, providing the original power required for the cutting operation. The drive motor 6 converts electrical energy into rotational kinetic energy, and the reducer 7 reduces the speed and increases the output torque to provide sufficient force to pull and cut the belt, avoiding unstable power for manual or tractor traction. When using it, first place the belt to be cut between the pressure roller 3 and the drive roller, then install the blade in the cutting groove on the blade box 502, and insert the bottom end into the positioning groove. Then start the drive motor 6 to drive the reducer 7 to rotate. The personnel initially guide the belt to cut the head, and then guide the belt to the other end between the pressure roller 3 and the drive roller.

[0022] Example 2: Please refer to Figure 2 Based on Example 1, it also has the following structure: It also includes guide rollers 203, which constrain and guide the belt in the width direction before it enters the pressure roller 3 to prevent the belt from running off-center. They are slidably set in the grooves opened on the left and right sides of the top of the placement platform 1. The grooves are equipped with limiting devices 2, which are composed of fixing blocks 201 and insert plates 202. The fixing blocks 201 are equidistantly set at the front and rear ends of the grooves. The bottom end of the guide rollers 203 is provided with insert plates 202. The insert plates 202 are U-shaped. Their vertical ends are inserted into the limiting grooves formed between two adjacent fixing blocks 201, and their horizontal ends abut against the top of the fixing blocks 201. By inserting the U-shaped insert plates 202 between the fixing blocks 201 at different positions, the distance between the two guide rollers 203 can be quickly and steplessly adjusted to adapt to belts of various widths.
