The reference shaft 4 is installed in the corresponding mounting hole through two sets of bearings. A reference roller 6 and an adjusting roller 7 are respectively installed at one end of the reference shaft 4 and the adjusting shaft 14 by a key connection. A first power source 1 is provided on one side of the support block 5. The output end of the first power source 1 is connected to the other end of the reference shaft 4 and the adjusting shaft 14 by a synchronous belt mechanism 2, for driving the reference shaft 4 and the adjusting shaft 14 to rotate in opposite directions.

[0020] The first power source 1 is connected by a servo motor and a reducer, and is fixed to the body of the cheese slice filling machine (not shown in the figure) by a mounting bracket 3. The synchronous belt mechanism 2 includes a driving pulley 201, an intermediate pulley 203, and two driven pulleys 204. The driving pulley 201 is installed at the output end of the reducer of the first power source 1. The two driven pulleys 204 are respectively located at the other end of the reference shaft 4 and the adjusting shaft 14. The intermediate pulley 203 is mounted on a wheel axle 205 by bearings and fixed to the body of the cheese slice filling machine by the wheel axle. The synchronous belt 202 is sequentially wound between the driving pulley, the intermediate pulley, and the two driven pulleys and is arranged in an S-shape between the intermediate pulley and the driven pulleys.

[0021] An eccentric sleeve 10 is installed in the mounting hole corresponding to the adjusting shaft 14 on the supporting cube 5 through two sets of bearings. The end of the eccentric sleeve 10 away from the adjusting roller 7 protrudes from one side of the supporting cube 5. The adjusting shaft 14 is installed through the eccentric hole of the eccentric sleeve 10 through two sets of bearings, and two nested spacers 15 are provided between the two sets of bearings. The eccentricity of the eccentric hole in the eccentric sleeve 10 is 4mm.

[0022] A second power source 11 is arranged on one side of the supporting cube 5, and is connected by a servo motor and a speed reducer and fixed on the body of the cheese slice filling machine (not shown in the figure) through a mounting bracket 3. The output end of the second power source 11 is connected with one end of the eccentric sleeve 10 through a synchronous belt assembly 9, and is used to drive the eccentric sleeve 10 to rotate, so as to drive the eccentric rotation of the adjusting shaft 14. The driven wheel 901 of the synchronous belt assembly 9 is fixed on one end of the eccentric sleeve 10 through the circumferentially distributed screws.

[0023] The bearing end cover 8 is fixed on both ends of the mounting hole corresponding to the adjusting shaft 14 on both sides of the supporting cube 5 through screws, and is sleeved on the eccentric sleeve 10 and abuts against the corresponding bearing outer ring through the clearance fit. The oil seal 17 is arranged between the other end of the eccentric sleeve 10, the adjusting shaft 14 and the sealing seat.

[0024] The bearing end cover 8 is also fixed on both ends of the mounting hole corresponding to the reference shaft 4 on both sides of the supporting cube 5, and is sleeved on the reference shaft 4 and abuts against the corresponding bearing outer ring.

[0025] The swing arm 13 is arranged between the mounting brackets 3 of the first power source 1 and the second power source 11, and the lower end of the swing arm 13 is hinged on the body of the cheese slice filling machine through a short shaft. The rotatable pressing wheel 12 is arranged on the upper end of the swing arm 13 through an axle and a bearing. The torsional spring 16 is sleeved on the short shaft of the lower end of the swing arm 13, and the two ends of the torsional spring 16 are clamped on the axle of the upper end of the swing arm 13 and one of the mounting brackets 3, and is used to tightly press the pressing wheel 12 on the synchronous belt of the synchronous belt mechanism 2.

[0026] In work, the supporting cube 5, the mounting bracket, the axle of the intermediate wheel and the short shaft of the lower end of the swing arm 13 of the device are fixed on the body of the cheese slice filling machine. The servo motor of the first power source 1 is started, the reference shaft 4 and the adjusting shaft 14 are driven to rotate towards each other through the synchronous belt mechanism 2, so as to drive the reference roller 6 and the adjusting roller 7 to rotate towards each other at the same time, and the thickness of the cheese slice between them is extruded and the cheese slice is pulled downward.

[0027] When it is necessary to adjust the thickness of the cheese slice, the servo motor of the second power source 11 is controlled to start, the eccentric sleeve 10 is driven to rotate through the synchronous belt assembly, so as to drive the eccentric rotation of the adjusting shaft 14, and then adjust the gap between the adjusting roller 7 and the reference roller 6, so as to realize the thickness of the extruded cheese slice.
