[0002] CNC band saw paper cutters are highly efficient and precise automated equipment widely used in a variety of industries, including paper processing, paper trading, paper mills, paper warehouses, and cardboard mills. Their operating principle is relatively simple and highly effective. First, the material to be cut is placed on an automatic loading and unloading paper hauler. A computer control system then automatically controls the operation, setting parameters such as cutting speed, angle, depth, and feed rate. These parameters depend on the type, thickness, and hardness of the material being cut. The control system then sends instructions to the mechanical components, moving the band saw along a predetermined path and within predetermined parameters, completing the cutting operation. The band saw is driven by a motor through a transmission mechanism, including pulleys and an electronic clutch. Finally, after cutting is complete, the machine automatically unloads the cut material, removing it from the work area for the next cut or packaging. The workflow of a CNC band saw paper cutter includes material loading, automatic positioning, setting processing parameters, the cutting process, unloading, and displaying the cut.

[0003] Deficiencies of existing technology: During the cutting process of the CNC band saw paper cutter, the band saw is driven by the band saw driving wheel. In order to facilitate timely replacement of the band saw on the band saw driving wheel, the band saw and the band saw driving wheel are fixed loosely, resulting in too little tension on the saw blade during cutting, which easily causes the saw blade to swing, affecting the paper cutting effect.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The CNC band saw paper cutter involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Reference Figure 1 The utility model provides a CNC band saw paper cutter, including a saw band tension device 1, a saw band cutting device 2 is connected to a rotating shaft on one side of the saw band tension device 1, and a paper feeding device 3 is fixedly connected to one side of the saw band cutting device 2.

[0022] What needs to be specifically explained in this embodiment is that the saw band tension device 1 increases the band saw tension of the saw band cutting device 2 when cutting paper materials. The specific structure and working principle of the above components will be described in detail later.

[0023] Reference Figure 2The saw band tensioning device 1 includes a saw band driving motor 101, the top of the saw band driving motor 101 is fixedly connected to a motor heat conductive block 102, one side of the motor heat conductive block 102 is fixedly connected to a saw wheel heat conductive pipe 103, one end of the saw wheel heat conductive pipe 103 is fixedly connected to a main wheel assembly shell 205, the back of the saw band driving motor 101 is bolted to a motor mounting plate 108, the top of the motor heat conductive block 102 is fixedly connected to the inner side of the top of the motor mounting plate 108, the top of the motor mounting plate 108 is fixedly connected to a thermal expansion air pipe 104, the top of the thermal expansion air pipe 104 is movably sleeved with a movable plunger 105, the top of the movable plunger 105 is threadedly connected to a band saw wheel connecting piece 106, and one side of the band saw wheel connecting piece 106 is fixedly connected to a band saw wheel shaft fixing piece 107.

[0024] What needs to be specifically explained in this embodiment is that the motor heat conductive block 102 transfers the heat generated by the saw belt driving motor 101 to the bottom of the heat expansion air pipe 104 to heat the heat expansion gas in the heat expansion air pipe 104. The effect of the saw wheel heat conductive pipe 103 is the same as 012. The saw wheel heat conductive pipe 103 transfers the heat in the main wheel assembly shell 205 to the motor heat conductive block 102. In addition, it should be emphasized that the heat expansion air pipe 104 and the movable plunger 105 are directly in a movable sleeve relationship and are sealed. The gas stored in the heat expansion air pipe 104 will not leak, and the saw belt is stretched. The overall effect of the force device 1 is to fill the air pipe with gas that is easily expanded when heated and connect it to a movable plunger. The heat generated by the friction between the motor-driven band saw and the band saw and the rotating wheel causes the gas to heat and expand, thereby pushing the movable plunger up to increase the tension of the band saw. This is beneficial to solving the problem that during the cutting process of the CNC band saw paper cutter, the band saw is driven by the band saw driving wheel, and in order to facilitate timely replacement of the band saw on the band saw driving wheel, the band saw and the band saw driving wheel are fixed loosely, resulting in too little tension on the saw blade during cutting, which easily causes the saw blade to swing and results in poor paper cutting effect.

[0025] Reference Figure 3 and Figure 4 The saw band cutting device 2 includes a motor drive wheel group 201, the back of the motor drive wheel group 201 is fixedly connected to the saw band drive motor 101, the back of one end of the motor drive wheel group 201 is fixedly connected to the band saw drive main wheel 202, the side of the band saw drive main wheel 202 is sleeved with a cutting band saw 203, the inner side of the top of the cutting band saw 203 is sleeved with a band saw drive auxiliary wheel 204, the front and back rotating shafts of the band saw drive main wheel 202 are connected to the main wheel assembly shell 205, the middle bolt on the top of the main wheel assembly shell 205 is connected to the paper tray 206, and the bottom bolt of the main wheel assembly shell 205 is connected to the placement base plate 207.

[0026] What needs to be specifically explained in this embodiment is that the motor drive wheel group 201 is composed of three gears, which are meshed with each other. The saw band drive motor 101 and the band saw drive main wheel 202 are respectively fixedly connected to the gears at both ends of the motor drive wheel group 201. The rotating shaft of the band saw drive auxiliary wheel 204 is fixed on the band saw wheel shaft fixing part 107. The tension is increased by raising the band saw drive auxiliary wheel 204. A slide rail is provided at the bottom of the paper tray 206 for placing the cut paper.

[0027] Reference Figure 5 The paper feeding device 3 includes a CNC machine tool 301, the top of the CNC machine tool 301 is movably connected to a reciprocating movable plate 302, the top of the reciprocating movable plate 302 is bolted to a feeding movable track 303, one end of the top of the feeding movable track 303 is electrically connected to a paper material clamp 304, and one end of the feeding movable track 303 is bolted to a feeding drive assembly 305.

[0028] What needs to be specifically explained in this embodiment is that the reciprocating movable plate 302 can move back and forth, the feeding movable track 303 can move back and forth horizontally, the paper material clamp 304 is used to clamp the paper material, and the specific control effect of the paper feeding device 3 is a conventional technical means known to those skilled in the art, so it will not be described in detail in this embodiment.

[0029] The working principle of the present invention is as follows: the motor heat conducting block 102 transfers the heat generated by the saw band driving motor 101 to the bottom of the heat expansion air pipe 104 to heat the heat expansion gas in the heat expansion air pipe 104. The effect of the saw wheel heat conducting pipe 103 is the same as 012. The saw wheel heat conducting pipe 103 transfers the heat in the main wheel assembly shell 205 to the motor heat conducting block 102. The overall effect of the saw band tensioning device 1 is to fill the air pipe with heated and easily expandable gas and connect it with a movable plunger. The heat generated by the motor-driven band saw and the friction between the band saw and the rotating wheel causes the gas to heat and expand, thereby pushing the movable plunger to rise to increase the tension of the band saw, which is beneficial to solving the problem that during the cutting process of the CNC band saw paper cutter, the band saw is driven by the band saw driving wheel, and in order to facilitate the timely replacement of the band saw on the band saw driving wheel, the band saw and the band saw driving wheel are fixed loosely, resulting in too little tension on the saw blade during cutting, which easily causes the saw blade to swing and causes poor paper cutting effect.
