The extruding device is used for extruding the material at the corresponding transverse sealing position of the cheese slice, and cutting the accumulated material according to the length of the bag, so as to facilitate the subsequent transverse sealing.

[0003] The existing material level adjusting device comprises a fixed seat, an adjusting screw threadedly connected to the fixed seat, an activity plate connected to the front end of the adjusting screw, and a slot-shaped support on which the activity plate is slidingly installed. When adjusting, the position of the activity plate is adjusted by manually rotating the adjusting screw, and the material level in the cheese slice packaging material is adjusted by the cooperation of the activity plate and the slot-shaped support.

[0004] This cheese slice material level adjusting device needs to manually adjust the material level, which is not only inconvenient to adjust, but also inaccurate to adjust the material level, and is easy to cause the control system to react too slowly, resulting in too little weight of the cheese slice or the material discharging and material overflowing. SUMMARY

[0006] To solve the above problems, the present application adopts the following technical scheme: A cheese slice material level adjusting device comprises a fixed seat, a rotary encoder installed on the fixed seat, a shaft sleeve provided on one side of the fixed seat, a rotatable transmission shaft installed in the shaft sleeve through a bearing, a swing rod fixed to one end of the transmission shaft through a synchronous belt mechanism and a center shaft of the rotary encoder, and the swing rod is L-shaped and the short rod is inserted into the transmission shaft along the radial direction of the transmission shaft, and the packaging material of the cheese slice is placed on the long rod of the swing rod, and the swing rod is swung to drive the transmission shaft to rotate according to the discharging amount of the cheese slice. A fan-shaped window is provided on a large pulley of the synchronous belt mechanism, and a positioning pin is provided on the fixed seat, and the positioning pin passes through the fan-shaped window to limit the rotation angle of the large pulley.

[0007] As a further optimization, the synchronous belt mechanism is composed of a large pulley provided at one end of the transmission shaft, a small pulley provided on the center shaft of the rotary encoder, and a synchronous belt connecting the large pulley and the small pulley.

[0008] As a further preferred, the pressure rod is fixed by a sleeve near the large pulley of the synchronous belt mechanism on the transmission shaft, the included angle between the pressure rod and the swing rod is close to 90 degrees, and the swing rod is used to control the swing rod to always lean on the cheese slice packaging material.

[0009] As a further preferred, the transmission ratio of the synchronous belt mechanism is 1:6.

[0010] As a further preferred, the fixed seat is connected by screws by a rectangular mounting plate and an L-shaped support provided at one end of the mounting plate, and the rotary encoder is fixed on the mounting plate and the center shaft penetrates the mounting plate.

[0011] The beneficial effects of the present application are: 1. By the cheese slice packaging material leaning on the long rod of the swing rod, the swing rod can be controlled to swing according to the cheese slice discharge amount, thereby driving the transmission shaft to rotate, and then driving the center shaft of the rotary encoder to rotate through the synchronous belt mechanism, so that the rotary encoder can output a signal to the controller of the cheese slice filling machine, and the cheese slice discharge amount can be controlled, so that the material level can be automatically adjusted, and the discharge speed can be accurately controlled.

[0019] A shaft sleeve 3 is arranged on the side of the mounting plate 9 of the fixing base, the outer edge of the shaft sleeve 3 is stepped and arranged perpendicularly to the mounting plate 9, a rotatable transmission shaft 2 is arranged in the shaft sleeve 3 through two sleeve bearings, one end of the transmission shaft 2 is connected with the central shaft of the rotary encoder 10 through a synchronous belt mechanism, the other end of the transmission shaft 2 is fixed with a swing lever 1, the swing lever 1 is L-shaped and the short rod is inserted into the transmission shaft 2 radially and is fixed through a jackscrew arranged on the other end of the transmission shaft 2. The packaging material of the cheese slice is arranged along the vertical direction and is in close contact with the long rod of the swing lever 1, which is used to control the swing of the swing lever 1 according to the discharging amount of the cheese slice, so as to drive the transmission shaft 2 to rotate.

[0020] The synchronous belt mechanism is composed of a large pulley 7 fixed on one end of the transmission shaft 2, a small pulley 13 arranged on the central shaft of the rotary encoder 10, and a synchronous belt 12 connecting the large pulley 7 and the small pulley 13. The transmission ratio of the synchronous belt mechanism is preferably 1:6.

[0021] A sector window 701 is arranged on the large pulley 7 of the synchronous belt mechanism, and a positioning pin 8 is fixed on the mounting plate 9 of the fixing base corresponding to the sector window 701, the positioning pin 8 penetrates the sector window 701, which is used to limit the rotation angle of the large pulley 7, so as to limit the swing angle of the swing lever 1. When the short rod of the swing lever 1 is rotated to a 45-degree angle with the horizontal center line of the large pulley 7 under the pushing of the cheese slice, the positioning pin 8 is close to the upper edge of the sector window 701.
