Description

Technical Field

[0001] The invention relates to the technical field of sponge processing equipment, in particular to a sponge cutting machine host and a sponge cutting machine. Background Art

[0002] The existing sponge cutting machine has a knife belt installed around the driving wheel and the passive wheel. The rotation of the driving wheel and the passive wheel drives the knife belt to rotate at high speed to cut the sponge. When the position of the knife belt needs to be adjusted, the installation position of the driving wheel and the passive wheel is usually manually adjusted to achieve the position adjustment of the knife belt. The adjustment process is time-consuming and labor-intensive, which reduces production efficiency; after the knife belt is adjusted, the cutting accuracy cannot be guaranteed, and the equipment operation is unstable.

[0003] Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0004] In view of the above technical problems, the present invention provides a sponge cutting machine host and a sponge cutting machine, which can adjust the position of the knife belt by automatically adjusting the position of the knife holder seat as a whole, saving time and effort and improving the production efficiency of the equipment; the knife belt has high adjustment accuracy, which ensures the cutting accuracy of the sponge and improves the product quality; after the knife belt is adjusted, the force is evenly applied when cutting the sponge, which avoids the stress concentration of the knife belt and causes breakage, thereby extending the service life of the knife belt.

[0005] To achieve the above object, the technical solution of the present invention is:

[0006] A sponge cutting machine host comprises a frame, on which a knife holder device, a knife box assembly and a knife holder forward and backward moving mechanism are arranged;

[0007] The tool holder device comprises a tool holder seat, a knife belt, a driving wheel assembly and a passive wheel assembly, wherein the driving wheel assembly and the passive wheel assembly are respectively arranged on the tool holder seat, and the knife belt is arranged between the driving wheel assembly and the passive wheel assembly in an upper and lower manner;

[0008] The lower part of the knife belt is located in the knife box assembly, and the part thereof extending out of the knife box assembly is the cutting part;

[0009] The tool holder seat is arranged on the tool holder forward and backward moving mechanism, and the tool holder forward and backward moving mechanism drives the tool holder seat to move forward and backward, and automatically adjusts the extension length of the knife belt in the knife box assembly.

[0010] The main machine of the sponge cutting machine can adjust the position of the knife belt by automatically adjusting the position of the knife holder seat as a whole, without the need for manual adjustment, thus saving time and effort; the adjustment process does not require shutdown and does not interrupt production, thus improving the production efficiency of the equipment.

[0011] The extended length of the knife belt in the alloy knife box directly affects the cutting depth. The position of the knife belt is adjusted by the forward and backward moving mechanism of the knife holder. The cutting depth can be flexibly controlled according to the thickness of the sponge or process requirements to ensure uniform slicing.

[0012] The knife belt will gradually wear during high-speed cutting, resulting in reduced cutting efficiency. By adjusting the extended length of the knife belt by moving it back and forth, the unworn part can be extended to the cutting position, reducing the frequency of frequent replacement of the knife belt and reducing the cost of use.

DETAILED DESCRIPTION

[0088] The present invention will be further described in detail below with reference to the embodiments in the accompanying drawings.

[0089] like Figures 1 to 14 As shown, the sponge cutting machine host of the present invention is a specific embodiment.

[0090] like Figure 1 As shown, the main body of the sponge cutting machine of this embodiment includes a frame 100, on which a knife holder device 200, a knife box assembly 300 and a knife holder forward and backward moving mechanism 400 are arranged;

[0091] The tool holder device 200 includes a tool holder seat 210, a knife belt 220, a driving wheel assembly 230 and a driven wheel assembly 240. The driving wheel assembly 230 and the driven wheel assembly 240 are respectively arranged on the tool holder seat 210, and the knife belt 220 is arranged between the driving wheel assembly 230 and the driven wheel assembly 240 in an up-and-down manner.

[0092] The lower part of the knife belt 220 is located in the knife box assembly 300, and the part thereof extending out of the knife box assembly 300 is the cutting part;

[0093] The knife holder seat 210 is arranged on the knife holder forward and backward moving mechanism 400, and the knife holder forward and backward moving mechanism 400 drives the knife holder seat 210 to move forward and backward, and automatically adjusts the extension length of the knife belt 220 in the knife box assembly 300;

[0094] The drive motor 290 is fixed on the knife holder seat 210 , and the drive motor 290 is connected to the driving wheel assembly 230 through a belt and a pulley transmission to drive it to rotate, thereby driving the knife belt 220 to rotate at a high speed, and the lower part of the knife belt 220 cuts the sponge S. Figure 1 and Figure 3 The direction of the middle arrow indicates the moving direction of the sponge S. Figure 8 It is a structural stereogram of the tool holder seat 210.

[0095] The main machine of the sponge cutting machine can adjust the position of the knife belt by automatically adjusting the position of the knife holder seat as a whole, without the need for manual adjustment, thus saving time and effort; the adjustment process does not require shutdown and does not interrupt production, thus improving the production efficiency of the equipment.

[0096] The extended length of the knife belt in the alloy knife box directly affects the cutting depth. A photoelectric sensor can be set to determine the position of the knife belt. The position of the knife belt can be adjusted by rotating the servo motor of the knife holder forward and backward moving mechanism. The cutting depth can be flexibly controlled according to the thickness of the sponge or process requirements to ensure uniform slicing.

[0107] One end surface of the top knife plate 340 is pressed against the rear end surface of the knife belt 220, and the other end surface opposite thereto is fixedly connected to the top knife rod 350, and the top knife rod 350 is transmission-connected to the top knife forward and backward moving mechanism 360;

[0108] The top knife forward and backward moving mechanism 360 drives the top knife rod 350 to drive the top knife plate 340 to move forward and backward synchronously with the knife belt 220.

[0109] The top blade plate 340 is pressed against the rear end surface of the knife belt 220 to ensure that the knife belt 220 will not retreat due to resistance during cutting, thereby avoiding cutting interruption or deviation; the top blade plate 340 cooperates with the knife belt 220 to move forward and backward synchronously to maintain the stability of the cutting process.

[0117] The knife holder angle adjustment mechanism drives the knife holder seat to rotate and automatically adjust the cutting angle between the knife belt and the sponge, so that the contact surface between the knife belt and the sponge is more closely fitted, reducing the cutting resistance and avoiding deformation or tearing of the sponge. A reasonable knife belt angle can reduce cutting vibration, ensure a smooth and flat cut surface, meet product thickness requirements, and reduce subsequent finishing processes. Dynamic adjustment of the knife belt angle can avoid excessive wear on one side of the knife belt and extend the overall service life of the knife belt.
