Description

Technical Field

[0001] The utility model belongs to the technical field of transport belt maintenance, and in particular relates to a belt bonding and stripping tool. Background Art

[0002] In metallurgical enterprises, mines, power plants and other units, material transport belt conveyors are the most important equipment, which runs through the entire conveying system. Therefore, the belt is a key component of the conveyor. It runs through the entire length of the conveyor, is used in large quantities, is expensive, and accounts for about 50% of the cost of the conveyor. During operation, the conveyor belt often suffers from abnormal wear or damage, or even breaks, which means that the quality of the belt interface bonding directly affects the normal operation of the entire transportation system.

[0003] At present, the cutting and stripping of the step platform of the belt joint are all manual operations. The strength and feel of the operator's knife determine the quality of the belt joint. The current operating standard is that the depth of the mistaken cutting of the lower belt core during stripping shall not exceed 50% of the belt core thickness, and the length of the mistaken damage of each step shall not exceed 10% of the total length. This operation can only be completed by people with many years of experience. In order to avoid failures caused by insufficient strength of the newly made rubber joints of the belt, various factories and mines generally increase the safety factor of the conveyor belt in the design to compensate. Therefore, a belt bonding cutting and stripping tool is designed, which can fully guarantee the cutting depth of the step wire core body, thereby ensuring the quality of the bonding head, reducing the difficulty of getting started, improving the quality of maintenance, and effectively avoiding hidden internal defects in the belt bonding head. Utility Model Content

[0004] The utility model provides a belt bonding and stripping tool to solve the problem that belt cutting needs to rely on experienced operators, which is time-consuming and labor-intensive, and has large manual operation errors.

[0005] The technical scheme of the utility model is: a belt bonding and stripping tool, characterized in that it comprises a tool handle, a tool groove is provided on the tool handle, a belt cutting blade is movably connected in the tool groove, a blade limit scale is provided on the side of the tool handle, and a pulley is connected to the bottom of the tool handle.

[0006] As a further improvement of the utility model, a locking screw is threadedly connected to the front side of the tool handle, and the end of the locking screw is pressed against the belt cutting blade to adjust the extension length of the belt cutting blade.

[0007] As a further improvement of the utility model, a presser foot is provided at the bottom of the tool handle, and an observation hole is opened on the side of the presser foot. The observation hole is opened to the front end of the knife groove, so that the real-time position of the belt cutting blade can be observed, which is convenient for adjustment.

[0008] As a further improvement of the present invention, a plurality of cutting limit points are provided on the blade limit scale for quickly pushing the blade to the cutting position.

[0009] As a further improvement of the utility model, a blade viewing window is provided on the outer surface of the tool handle, and the blade viewing window is closely connected with the blade limit scale.

[0010] The beneficial effects of the utility model are as follows: the utility model uses the tool limit scale and observation hole to enable the belt cutting blade to accurately adjust the cutting size and depth along the scale when cutting, so as to achieve precise operation, and no longer need to rely entirely on experienced masters to operate as before, which greatly improves the working efficiency and safety of the conveyor; through the presser foot and pulley, the tool can be cut along the line simply and labor-saving, avoiding manual operation errors, improving the alignment accuracy, effectively ensuring the cutting thickness accuracy, thereby ensuring the quality of the bonding head, and effectively improving the transportation level of the entire conveyor. The utility model has a simple structure, is easy to use, easy to operate, and has great adaptability and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] like Figure 1 — Figure 3 As shown, a belt bonding and stripping tool is characterized in that it includes a tool handle 1, a tool groove 8 is provided on the tool handle 1, a belt cutting blade 2 is movably connected in the tool groove 8, a blade limit scale 5 is provided on the side of the tool handle 1, and a pulley 6 is connected to the bottom of the tool handle 1.

[0018] The front side of the tool handle 1 is connected with a locking screw 4 through a thread, and the end of the locking screw 4 is pressed against the belt cutting blade 2 for adjusting the belt cutting blade 2 .

[0019] A presser foot 3 is provided at the bottom of the tool handle 1, and an observation hole 7 is opened on the side of the presser foot 3. The observation hole 7 is opened to the front end of the knife groove 8. When in use, the real-time position of the belt cutting blade 2 can be observed for easy adjustment.

[0020] The blade limit scale 5 is provided with a plurality of cutting limit points, and the corresponding limit points can be selected according to the rubber surface or canvas surface to be cut, so as to facilitate the adjustment of the length of the belt cutting blade 2.

[0021] A blade viewing window 9 is provided on the outer surface of the tool handle 1 , and the blade viewing window 9 is closely connected to the blade limit scale 5 .

[0022] When in use, according to the thickness of the rubber layer or canvas layer to be cut, select a suitable limit point on the blade limit scale 5, adjust the extension size of the belt cutting blade 2, tilt the tool handle 1, make the presser foot 3 fit and position with the rubber surface or canvas surface of the belt, observe through the observation hole 7 whether the belt cutting blade 2 cuts into the belt rubber layer and does not "overcut" the rubber surface canvas layer, slightly adjust the position of the belt cutting blade 2 according to the actual situation, and use the locking bolt 4 to lock the belt cutting blade 2. When cutting, drag the tool handle 1 to move the roller 6 along the cutting line, and observe through the observation port 7 so that the belt cutting blade 2 can cut along the line.
