Description

Technical Field

[0001] This invention belongs to the field of packaging machinery, and specifically relates to a cheese slice filling machine. Background Technology

[0002] Cheese slices, also known as cheese chips, are a common dairy product, usually made from fermented milk. They have a rich milky aroma and abundant nutritional value. They are widely used in daily diets, serving as a ready-to-eat snack or as an ingredient in sandwiches, hamburgers, baked goods, and more.

[0003] A cheese slice filling machine is a food packaging device specifically designed for the automated production of cheese slices. It is widely used in dairy processing, food manufacturing, and other industries. Since cheese raw materials are mostly processed cheese or natural cheese, they need to be heated to a suitable temperature (usually 60–80°C) to reduce viscosity and facilitate pumping and shaping.

[0004] Currently, there are very few mature cheese slice filling machines on the market. Most of the filling equipment described in publicly available information pertains to cheese filling machines that use bottles or boxes for packaging. For example, CN120364207A discloses a filling machine for high-viscosity liquid cheese, which can fill high-viscosity liquid cheese into cheese boxes. This type of filling equipment can only fill cheese packaged in bottles or boxes; it cannot automatically form, fill, seal, and cut sliced ​​cheese. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cheese slice filling machine that can automatically form, fill, seal and cross-cut sliced ​​cheese slices with a high degree of automation and production efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution: A cheese slice filling machine includes a machine body with a unwinding mechanism for holding cheese slice packaging material rolls to be used. The machine body is characterized by having a forming and feeding device, a thickness adjustment device, an extrusion device, and a horizontal sealing device arranged sequentially from top to bottom in the middle of the machine body. These devices are used to perform forming and feeding, thickness adjustment, extrusion at the horizontal sealing position, and horizontal sealing of the cheese slice packaging material, respectively. A cross-cutting device is provided on the machine body at the end away from the unwinding mechanism. The cross-cutting device includes a mounting plate frame. On one side of the mounting plate frame, from top to bottom, there are a feeding mechanism, a cross-cutting mechanism, a discharging mechanism, and a breaking mechanism, which are used to cross-cut and break the cheese slices. The extrusion device includes a support plate frame, on which two sets of driven rollers and driving rollers are installed side by side. An extrusion belt is wound between each set of driven rollers and driving rollers. Multiple rectangular protrusions are evenly distributed on the outer edge of the extrusion belt. The rectangular protrusions on the two extrusion belts correspond one-to-one, and the center distance between two adjacent rectangular protrusions is equal to the center distance between two adjacent horizontal sealing positions on the cheese slice. Multiple vertically arranged adjusting shafts are evenly distributed on the support plate frame between each group of driven rollers and driving rollers. The adjusting shafts are eccentric shafts, and a rotatable tensioning roller is installed on the eccentric shaft section in the middle of each adjusting shaft to tension the extrusion belt to extrude the cheese slices. A first power source consisting of a servo motor and a reducer is provided on the rear side of the support plate frame. The output end of the power source is connected to one end of the central shaft of one of the active rollers, and the central shafts of the two active rollers are connected to each other to drive the two extrusion belts to run in opposite directions.

[0007] As a further preferred embodiment, the support plate frame includes a main upright plate and two secondary upright plates arranged in parallel. The two secondary upright plates are respectively fixed to the front side of the main upright plate by a connecting plate. Each set of driven rollers and driving rollers is installed between a secondary upright plate and the main upright plate. The front sides of the two secondary upright plates are detachably connected by a rectangular plate frame.

[0008] As a further preferred embodiment, a positioning plate is fixed on the inner side of each separate plate. Multiple positioning holes are evenly distributed on the positioning plate along the vertical direction. Each positioning hole is connected to an L-shaped notch and a locking screw is provided at the L-shaped notch. The front end of the adjusting shaft passes through the corresponding positioning hole and is locked by the locking screw to adjust the eccentricity of the adjusting shaft, thereby adjusting the extrusion gap between the two extrusion belts.

[0009] As a further preferred embodiment, the cross-cutting mechanism includes two support plates connected to each other by a connecting block. A rotatable cutting roller and a support roller are installed side by side between the two support plates. Rectangular grooves are evenly distributed along the circumferential direction on the outer edge of the middle part of the cutting roller. Cutters are held in the rectangular grooves by pressure plates. The cutters are held between the pressure plates and the inner wall of one side of the rectangular grooves. Adjusting screws are evenly screwed into the cutting roller on the other side and bottom surface of each pressure plate. The inner end of the adjusting screw rests against the other side and bottom surface of the corresponding pressure plate to adjust the position and parallelism of the cutter. Two notches are symmetrically provided on one side of the blade of each cutter to form two connecting ribs between two adjacent cheese slices during cross-cutting. On the other side of the mounting plate frame, there is a second power source consisting of a servo motor and a reducer. The output end of the second power source is coaxially connected to the corresponding end of the cutter roller.

[0010] As a further preferred embodiment, grooves are respectively opened at both ends of the support rollers on the outer side of the two support plates, and sliding seats are installed in the grooves through sliding gaps. The two ends of the support rollers are respectively installed in the corresponding sliding seats through bearings. A sealing strip is fixed at one end of the grooves on the two support plates, and a pressure spring is provided between the sealing strip and the corresponding sliding seat to make the support roller elastically abut against the outer edge of the cutter roller.

[0011] As a further preferred embodiment, the feeding mechanism and the discharging mechanism have the same structure, including a fixed belt conveyor mechanism and a floating belt conveyor mechanism arranged left and right. The floating belt conveyor mechanism includes two base plates connected to each other by two connecting rods, and two movable plates connected to each other by a connecting plate. One base plate is fixed to one side of the mounting frame. Guide blocks are fixed in the middle of one side of each of the two base plates. The outer ends of the guide blocks are respectively inserted into the slide grooves in the middle of the movable plates through clearance fit. A pressure spring is provided between the base plate and the corresponding movable plate. A drive roller and two pressure rollers are rotatably installed between the two base plates. Two passive rollers are arranged vertically between the two movable plates through bearings. A right conveyor belt is wound around the drive roller and the two passive rollers and rests against one side of the connecting plate. The pressure roller presses on the right conveyor belt to facilitate the elastic clamping, feeding, and discharging of the cheese slices.

[0012] As a further preferred embodiment, the breaking mechanism includes two fixed belt conveyor mechanisms arranged symmetrically on the left and right sides, and the operating speed of the two fixed belt conveyor mechanisms is slightly higher than the belt running speed of the discharge mechanism.

[0013] As a further preferred embodiment, the thickness adjustment device includes a support cube, on which a rotatable reference shaft and an adjustment shaft are mounted side by side. A reference roller and an adjustment roller are respectively mounted at one end of the reference shaft and the adjustment shaft. A third power source is provided on one side of the support cube, which is connected to the reference shaft and the adjustment shaft for driving the reference roller and the adjustment roller to rotate in opposite directions. An eccentric sleeve is mounted in the mounting hole of the adjustment shaft on the support cube through a bearing. The end of the eccentric sleeve away from the adjustment roller protrudes from one side of the support cube. The adjustment shaft is mounted through the eccentric hole of the eccentric sleeve through a bearing. A fourth power source consisting of a servo motor and a reducer is provided on one side of the supporting cube. The output end of the fourth power source is connected to one end of the eccentric sleeve for driving the adjusting shaft to rotate eccentrically, thereby adjusting the gap between the reference roller and the adjusting roller.

[0014] As a further preferred embodiment, a material level adjustment device is provided on the machine body between the forming and feeding device and the thickness adjustment device. The material level adjustment device includes a fixed base and a bushing fixed on the machine body. A rotary encoder is installed on the fixed base, and a rotatable transmission shaft is installed in the bushing. One end of the transmission shaft is connected to the central shaft of the rotary encoder through a synchronous belt mechanism. An L-shaped swing arm is fixed at the other end of the transmission shaft. One end of the short rod of the swing arm is inserted into the transmission shaft radially. The packaging material of the cheese slice rests against the long rod of the swing arm. This is used to control the swing arm to swing according to the amount of cheese slice fed, so as to automatically adjust the material level and accurately control the feeding speed.

[0015] As a further preferred embodiment, a sector-shaped window is provided on the large pulley of the synchronous belt mechanism, and a positioning pin is provided on the fixed seat. The positioning pin passes through the sector-shaped window to limit the rotation angle of the large pulley.

[0016] The beneficial effects of this invention are: 1. Because the forming and feeding device, thickness adjustment device, extrusion device, and horizontal sealing device are arranged sequentially from top to bottom in the middle of the machine body, the forming and feeding, thickness adjustment, horizontal sealing position extrusion, and horizontal sealing of cheese slice packaging materials can be realized respectively, thereby realizing continuous packaging and forming of cheese slices with uniform specifications; Because a horizontal cutting device is provided on the end of the machine body away from the unwinding mechanism, the horizontal cutting device includes a feeding mechanism, a horizontal cutting mechanism, a discharging mechanism, and a breaking mechanism arranged sequentially from top to bottom on one side of the mounting plate frame, the continuous horizontal cutting and breaking of cheese slices can be realized, which facilitates subsequent stacking and packaging, with a high degree of automation and production efficiency.

[0017] 2. Since the extrusion device drives two extrusion belts to run in opposite directions through a first power source consisting of a servo motor and a reducer, the rectangular bosses on the two extrusion belts can cooperate with each other to achieve continuous extrusion of the cheese slice at the horizontal sealing position. The cheese slice does not need to stop its stepping during extrusion and can move synchronously with other devices of the cheese slice filling machine, further improving production efficiency.

[0018] 3. Because multiple adjusting shafts are evenly distributed between each group of driven rollers and driving rollers on the support plate frame, and the adjusting shafts are eccentric shafts with rotatable tension rollers installed on their eccentric shaft sections, the extrusion belt can be tightened by rotating the adjusting shafts and tension rollers to achieve the extrusion of cheese slice packaging material at the horizontal sealing position. Therefore, the extrusion is clean, and there is no material residue at the horizontal sealing position of the cheese slice after extrusion, which can avoid affecting the subsequent horizontal sealing device and improve the subsequent horizontal sealing effect.

[0019] 4. Since the cross-cutting mechanism drives the cutting roller to rotate through the second power source located on the other side of the mounting plate, the cheese slices can be cross-cut through the cooperation of the support roller. By symmetrically providing two notches on one side of each cutting blade, two connecting ribs can be formed between two adjacent cheese slices during cross-cutting, thus ensuring continuous and stable cutting of cheese slices, high working efficiency and long service life.

[0020] 5. Because adjusting screws are evenly screwed into the other side and bottom surface of each pressure plate on the cutting roller, with the inner end of the adjusting screw pressing against the other side and bottom surface of the corresponding pressure plate, the position and parallelism of the cutter can be easily adjusted, resulting in a good cutting effect.

[0021] 6. Because a separation cylinder is provided on the upper part of the L-shaped bracket on the outer side of the lower clamping plate, the L-shaped bracket can be pushed when the machine stops, so that the longitudinal sealing block is away from the packaging material sleeved on the forming support body; this can prevent the longitudinal sealing block from burning the packaging material when the machine stops, and from tearing the packaging material when the machine is restarted. 7. Because a counterweight rod is fixed on the outer side of the lower end of the L-shaped bracket, and a counterweight sleeve is provided on the counterweight rod, the clamping force of the longitudinal sealing block on the packaging material can be adjusted by sliding the counterweight sleeve along the counterweight rod and fixing it with the set screw. The adjustment is convenient and the sealing is firm and beautiful. 8. Since the feed tube is clamped between the upper bracket and the upper clamping plate, and a quick-release assembly is provided between the front end of the upper bracket and the upper clamping plate to lock the upper bracket and the upper clamping plate, the feed tube can be quickly disassembled, which facilitates quick cleaning after the machine stops.

[0079] like Figures 1-3 As shown, the present invention relates to a cheese slice filling machine, including a machine body 1, which is composed of a frame and a mounting plate 101 fixed on the frame. A unwinding mechanism is provided on the mounting plate 101 of the machine body 1 near the right end for placing the cheese slice packaging material roll to be used.

[0080] The unwinding mechanism includes two unwinding shafts 14 symmetrically mounted on a mounting plate 101 via bearings. The rear ends of the two unwinding shafts 14 pass through bearing sleeves on the mounting plate 101 and are connected to reduction motors 19. Two rotatable first guide rollers 16 are mounted on the mounting plate 101 near the outer edge of each unwinding shaft 14. A pair of rotatable clamping rollers 20 are mounted on the mounting plate 101 below the two unwinding shafts 14 via a mounting bracket 17. Four rotatable second guide rollers 15, approximately rectangular in arrangement, are mounted on the mounting plate 101 to guide the cheese slice packaging rolls to the tensioning mechanism 13 above. Three rotatable fourth guide rollers 12 are mounted on the mounting plate 101 above the tensioning mechanism 13 to guide the packaging rolls to the forming and unloading device.

[0081] like Figures 4-5As shown, the tensioning mechanism 13 includes a tensioning plate frame 1301 fixed on the mounting plate 101. At least three third steering rollers 1303 are rotatably mounted on the tensioning plate frame 1301. Two guide shafts 1302 are fixed inside the tensioning plate frame 1301. A sliding plate frame 1304 is slidably mounted on the two guide shafts 1302 via a slider. Two vertically arranged floating steering rollers 1305 are mounted on the sliding plate frame 1304. A tensioning cylinder 1306 and a tensioning chain 1307 are provided at one end of the tensioning plate frame 1301. The other end of the tensioning chain 1307 is connected to the sliding plate frame 1304 after being turned by the intermediate wheel 1308 provided on the tensioning plate frame 1301. A top wheel is installed at one end of the piston rod of the tensioning cylinder 1306 and meshes with the tensioning chain 1307 to tighten the tensioning chain 1307, thereby tightening the packaging material roll through the floating steering roller 1305.

[0082] like Figure 1 As shown, a forming and feeding device 11, a thickness adjustment device 9, an extrusion device 8, and a horizontal sealing device 2 are arranged sequentially from top to bottom on the mounting plate 101 in the middle of the machine body 1. These are used to realize the forming and feeding of cheese slice packaging materials, thickness adjustment, extrusion at the horizontal sealing position, and horizontal sealing, respectively.

[0083] like Figures 41-47 As shown, the forming and feeding device 11 includes a vertical plate 1111. A T-shaped upper support 1114 and a lower support 1118 arranged vertically are fixed on the vertical plate 1111 by screws. An upper clamping plate 1123 is hinged to one side of the upper support 1114 by a pin. Corresponding clamping blocks 1113 are fixedly connected to the opposite surfaces of the upper support 1114 and the upper clamping plate 1123 respectively. Corresponding rectangular grooves are provided on the opposite surfaces of the clamping blocks 1113 respectively, and guide strips 1112 are fixed to the bottom of the rectangular grooves by screws. A feeding tube 1116 is clamped between two clamping blocks 1113. A positioning block 1121 is fixedly sleeved on the upper outer edge of the feeding tube 1116. The feeding tube 1116 is clamped between the guide strips 1112 in the rectangular grooves of the two clamping blocks 1113 by the positioning block 1121. A quick-release assembly 1115 is provided between the front end of the upper bracket 1114 and the upper clamping plate 1123 to lock the upper bracket 1114 and the upper clamping plate 1123, thereby clamping the feeding tube 1116.

[0084] A forming support body 1119 is fitted outside the feeding pipe 1116. The lower part of the forming support body 1119 is a rectangular flat tube and its length is greater than that of the longitudinal sealing block 1101. The middle and upper parts of the forming support body 1119 are two symmetrically arranged cylinders. The two cylinders are located on both sides of the feeding pipe 1116 and their upper ends are clamped between two clamping blocks 1113 for easy disassembly.

[0085] A forming device 1117 is fixed to the outside of the lower support 1118 by an L-shaped support plate. The forming device 1117 is made of stainless steel plate bent into shape. A waist-shaped forming sleeve with a hollowed-out outer wall is provided on one side of the forming device 1117 and is fitted outside the middle part of the forming support 1119 to facilitate the forming of the packaging material.

[0086] A lower clamping plate 1110 is hinged to one side of the lower bracket 1118 via a pin. A quick-release assembly 1115 is also provided between the front ends of the lower bracket 1118 and the lower clamping plate 1110 for locking the lower bracket 1118 and the lower clamping plate 1110. The molded support body 1119 passes through the space between the lower bracket 1118 and the lower clamping plate 1110, and the lower end of the molded sleeve is also inserted between the lower bracket 1118 and the lower clamping plate 1110.

[0087] An L-shaped bracket 1107 is hinged to the outside of the lower clamping plate 1110 via a pin 1109. A longitudinal sealing block 1101 is hinged to the lower end of the L-shaped bracket 1107 via a pin 1103 and two rectangular plates 1102. The two rectangular plates 1102 are bolted to both sides of the longitudinal sealing block 1101. The longitudinal sealing block 1101 is vertically arranged and its inner side rests against the forming support body 1119. A separation cylinder 1108 is fixed to the upper part of the L-shaped bracket 1107 on the outside of the lower clamping plate 1110. This cylinder is used to push the L-shaped bracket 1107 when the machine stops, causing the longitudinal sealing block 1101 to move away from the packaging material fitted onto the forming support body 1119.

[0088] A counterweight rod 1104 is fixed to the lower outer side of the L-shaped bracket 1107 by a threaded connection. A counterweight sleeve 1105 is provided on the counterweight rod 1104. The counterweight sleeve 1105 and the counterweight rod 1104 are fitted with a sliding clearance and fixed by a set screw. The longitudinal sealing block 1101 is pressed against the lower side of the molding support body 1119 under the action of the counterweight sleeve 1105, so as to adjust the pressing force of the longitudinal sealing block 1101 on the packaging material.

[0089] An adjusting bolt 1106 is inserted through the middle of the L-shaped bracket 1107. The inner end of the adjusting bolt 1106 is connected to the longitudinal sealing block 1101 by a thread. A pressure spring 1122 is sleeved on the adjusting bolt 1106 on the outside of the L-shaped bracket 1107 to facilitate fine adjustment of the clamping force of the longitudinal sealing block 1101 on the packaging material.

[0090] A longitudinal groove is provided on the inner side of the longitudinal sealing block 1101, and a stainless steel pressure strip 1124 is embedded and fixed in the groove to facilitate longitudinal sealing of the packaging material. An elongated hole is provided on the longitudinal sealing block 1101 near the inner edge, and an electric heating tube 1125 is inserted therein to heat the longitudinal sealing block 1101. A guide block 1120 is inserted into and fixed to the lower end of the longitudinal sealing block 1101 with bolts. The guide block 1120 is provided with a wire groove, and the power cord of the electric heating tube 1125 is led out from the wire groove.

[0091] The quick-release assembly 1115 includes a connecting screw and a locking nut. One end of the connecting screw is hinged to the inner front end of the upper bracket 1114 or the lower bracket 1118 through a bushing and a pin. A U-shaped notch is provided at the front end of the upper clamping plate 1123 and the lower clamping plate 1110. The other end of the connecting screw is inserted into the corresponding notch and locked by a plum blossom-shaped locking nut.

[0092] In use, the film packaging material rolled out from the packaging material enters the forming sleeve of the forming machine 1117 through the unwinding mechanism. The gap between the forming sleeve and the forming support 1119 causes the two edges of the packaging material to overlap and form a flat tube. The longitudinal sealing block 1101 is heated by an external power source connected to the electric heating tube 1125. Under the action of the counterweight sleeve, the longitudinal sealing block 1101 is pressed against the overlapping edges of the packaging material by the pressure strip 24, achieving longitudinal sealing. Simultaneously, the heated liquid cheese is introduced into the longitudinally sealed packaging material through an external injection pump connected to the feeding pipe 1116. When the machine stops, the controller of the cheese slice filling machine activates the separation cylinder 1108 to extend, pushing the L-shaped bracket 1107 away from the packaging material on the forming support 1119, thus preventing damage to the packaging material.

[0093] like Figures 33-36 As shown, the thickness adjustment device 9 includes a support cube 905 fixed on the machine body 1. Two mounting holes of different sizes are arranged side by side on the support cube 905, and a rotatable reference shaft 904 and an adjusting shaft 914 are respectively installed through the two mounting holes. The reference shaft 904 is installed in the corresponding mounting hole through two sets of bearings. A reference roller 906 and an adjusting roller 907 are respectively installed at one end of the reference shaft 904 and the adjusting shaft 914 by a key. A third power source 901 is provided on one side of the support cube 905. The output end of the third power source 901 is connected to the other end of the reference shaft 904 and the adjusting shaft 914 through a synchronous belt mechanism 902, which is used to drive the reference shaft 904 and the adjusting shaft 914 to rotate in opposite directions.

[0094] The third power source 901 is connected to a servo motor and a reducer, and is fixed to the body 1 of the cheese slice filling machine by a mounting bracket 903. An eccentric sleeve 910 is installed in the mounting hole of the adjusting shaft 914 on the supporting cube 905 via two sets of bearings. One end of the eccentric sleeve 910, away from the adjusting roller 907, protrudes from one side of the supporting cube 905. The adjusting shaft 914 is installed through the eccentric hole of the eccentric sleeve 910 via two sets of bearings, and two nested spacers 915 are provided between the two sets of bearings. The eccentricity of the eccentric hole in the eccentric sleeve 910 is 4mm.

[0095] A fourth power source 911 is provided on one side of the supporting cube 905. The fourth power source 911 is composed of a servo motor and a reducer, and is fixed to the body 1 of the cheese slice filling machine through another mounting bracket 903. The output end of the fourth power source 911 is connected to one end of the eccentric sleeve 910 through a synchronous belt assembly 909, which drives the eccentric sleeve 910 to rotate, thereby driving the adjusting shaft 914 to rotate eccentrically. The driven wheel of the synchronous belt assembly 909 is fixed to one end of the eccentric sleeve 910 by circumferentially distributed screws.

[0096] Bearing end caps 908 are fixed to the two ends of the mounting holes of the adjusting shaft 914 on both sides of the supporting cube 905 by screws. The bearing end caps 908 are fitted onto the eccentric sleeve 910 with clearance fit and abut against the corresponding bearing outer ring. Oil seals 917 are installed between the other end of the eccentric sleeve 910, the adjusting shaft 914 and the sealing seat.

[0097] Bearing end caps 908 are also fixed at both ends of the mounting holes corresponding to the reference shaft 904 on both sides of the supporting cube 905. The bearing end caps 908 are fitted on the reference shaft 904 and abut against the corresponding bearing outer ring.

[0098] A swing arm 913 is provided between the mounting brackets 903 of the third power source 901 and the fourth power source 911. The lower end of the swing arm 913 is hinged to the body 1 of the cheese slice filling machine via a short shaft. A rotatable pressure wheel 912 is mounted on the upper end of the swing arm 913 via a wheel axle and bearings. A torsion spring 916 is sleeved on the short shaft at the lower end of the swing arm 913. The two ends of the torsion spring 916 are respectively clamped on the wheel axle at the upper end of the swing arm 913 and one of the mounting brackets 903, for pressing the pressure wheel 912 tightly onto the synchronous belt of the synchronous belt mechanism 902.

[0099] During operation, the servo motor of the third power source 901 is started by the controller, and the reference shaft 904 and the adjusting shaft 914 are driven to rotate in opposite directions by the synchronous belt mechanism 902, thereby driving the reference roller 906 and the adjusting roller 907 to rotate in opposite directions at the same time, compressing the thickness of the cheese slice passing between the reference roller 906 and the adjusting roller 907 and pulling the cheese slice downward.

[0100] When the thickness of the cheese slice needs to be adjusted, the servo motor of the fourth power source 911 is started, and the eccentric sleeve 910 is rotated through the synchronous belt assembly, which in turn drives the adjusting shaft 914 to rotate eccentrically, thereby adjusting the gap between the adjusting roller 907 and the reference roller 906, so as to achieve the desired thickness of the extruded cheese slice.

[0101] A material level adjustment device 10 is provided on the machine body 1, located between the forming and feeding device 11 and the thickness adjustment device 9. For example... Figures 37-40As shown, the material level adjustment device 10 includes a fixed base 1009 and a bushing 1003 fixed on the machine body 1. The fixed base 1009 is fixed to the back of the mounting plate 101 of the machine body 1 by an L-shaped support plate 1011. A rotary encoder is installed on the fixed base. The bushing 1003 passes through the mounting plate 101 of the machine body 1. A rotatable transmission shaft is installed in the bushing through a bearing. One end of the transmission shaft is connected to the central shaft of the rotary encoder through a synchronous belt mechanism. An L-shaped swing arm is fixed at the other end of the transmission shaft. One end of the short rod of the swing arm is fixedly inserted into the transmission shaft radially. The packaging material of the cheese slice rests on the long rod of the swing arm. The swing arm is used to control the swing arm to swing according to the amount of cheese slice fed, so as to automatically adjust the material level and accurately control the feeding speed.

[0102] The synchronous belt mechanism consists of a large pulley 1007 fixed at one end of the transmission shaft 1002, a small pulley 1013 mounted on the central shaft of the rotary encoder 1010, and a synchronous belt 1012 connecting the large pulley 1007 and the small pulley 1013. The preferred transmission ratio of the synchronous belt mechanism is 1:6.

[0103] A sector-shaped window is provided on the large pulley 1007 of the synchronous belt mechanism. A positioning pin 1008 is fixed on the fixed base at the corresponding position of the sector-shaped window. The positioning pin 1008 passes through the sector-shaped window and is used to limit the rotation angle of the large pulley 1007, thereby limiting the swing angle of the swing arm 1001. When the short rod of the swing arm 1001 rotates to a 45-degree angle with the horizontal center line of the large pulley 1007 under the push of the cheese slice, the positioning pin 1008 is close to the upper edge of the sector-shaped window.

[0104] A sleeve 1004 is fitted on the drive shaft 1002 near the large pulley 1007 of the synchronous belt mechanism and fixed with screws. A screw hole is provided on the outer edge of the sleeve 1004 along the radial direction and a pressure rod 1005 is screwed in and fixed. The angle between the pressure rod 1005 and one end of the short rod of the swing rod 1001 is close to 90 degrees. A nut counterweight 1006 is fixed on the outer end of the pressure rod 1005 to control the swing rod 1001 to always rest on the packaging material of the cheese slice.

[0105] During operation, the sealed cheese slice packaging material adheres tightly to the long rod of the swing arm 1001 and enters the thickness adjustment device 9. As the cheese slice material is fed into the packaging, a certain amount of material accumulates before entering the thickness adjustment device 9, pushing the swing arm 1001 to rotate the drive shaft 1002 clockwise. The greater the amount of material accumulated, the larger the angle at which the swing arm 1001 drives the drive shaft 1002 to rotate. When the drive shaft 1002 rotates, it drives the central shaft of the rotary encoder 1010 to rotate via a synchronous belt mechanism. The rotary encoder 1010 outputs a signal to the controller of the cheese slice filling machine. The controller then controls the flow rate of the injection pump based on the received signal from the rotary encoder 1010, thereby controlling the material level within the cheese slice packaging material.

[0106] like Figures 28-32 As shown, the extrusion device 8 includes a support plate frame 801. Two sets of driven rollers 803 and driving rollers 809 are arranged side by side on the support plate frame 801. An extrusion belt 802 is wound between each set of driven rollers 803 and driving rollers 809. The extrusion belt is a synchronous belt and multiple rectangular bosses 8021 are evenly distributed on the outer edge of each extrusion belt 802. The rectangular bosses 8021 on the two extrusion belts 802 correspond one-to-one, and the center distance between two adjacent rectangular bosses 8021 is equal to the center distance between two adjacent horizontal sealing positions on the cheese slice.

[0107] The support plate frame 801 includes a rectangular main upright plate 8011 and two separate upright plates 8012 arranged in parallel. The two separate upright plates 8012 are respectively fixed to the front side of the main upright plate 8011 by a connecting plate 8013 and screws. Each set of driven rollers 803 and driving rollers 809 are respectively installed between a separate upright plate 8012 and the main upright plate 8011. The front side of the two separate upright plates 8012 is detachably connected by screws through a rectangular plate frame 8014. The rear side of the main upright plate 8011 is fixed to the machine body 1 by two symmetrically fixed connecting plates 8015.

[0108] The central shaft 810 of the drive roller 809 is mounted on the main upright plate 8011 and the corresponding split plate 8012 via two bearing sleeves 811 and bearings. The bearing sleeves 811 are inserted into the corresponding main upright plate 8011 or split plate 8012 and fixed with screws for easy assembly and disassembly. The drive roller 809 is mounted on the corresponding central shaft 810 via a key connection, and multiple grooves that mate with the extrusion belt 802 are evenly distributed on the outer edge of the drive roller 809. The two ends of the central shaft 804 of the driven roller 803 pass through oblong holes provided on the main upright plate 8011 and the split plate 8012 respectively and are fixed with nuts 812. The driven roller 803 is mounted on the corresponding central shaft 804 via two sets of bearings for easy assembly and disassembly.

[0109] Multiple vertically arranged adjusting shafts 807 are evenly distributed on the support plate frame 801 between each group of driven rollers 803 and driving rollers 809. In this embodiment, three adjusting shafts are used as an example. One end of the adjusting shaft 807 is inserted into the through hole on the main upright plate 8011 through clearance fit, and the other end passes through the through hole on the corresponding separate plate 8012 through clearance fit and exits through the inner cavity of the rectangular plate frame 8014. The adjusting shaft 807 is an eccentric shaft, and a rotatable tensioning roller 805 is installed on the eccentric shaft section in the middle of each adjusting shaft 807 through a bearing. Multiple grooves that cooperate with the extrusion belt 802 are evenly distributed on the outer edge of the tensioning roller 805 to tighten the extrusion belt 802 to extrude the cheese slices.

[0110] A rectangular positioning plate 808 is fixed to the inner side of each separate plate 8012 by screws. Multiple positioning holes are evenly distributed on the positioning plate 808 along the vertical direction. Each positioning hole is connected to an L-shaped notch and a locking screw 806 is provided at the L-shaped notch. The front end of the adjusting shaft 807 passes through the corresponding positioning hole and is locked by the locking screw 806 to adjust the eccentricity of the adjusting shaft 807, thereby adjusting the gap between the two extrusion belts 802.

[0111] A first power source, consisting of a servo motor 817 and a reducer 816, is located on the rear side of the support frame 801. This first power source is fixed to a motor bracket 818 and further fixed to the rear side of the machine body 1. The output end of the first power source is connected to one end of the central shaft of one of the drive rollers 809 via a synchronous belt mechanism 819. The central shafts 810 of the two drive rollers 809 are connected by a gear pair 820, which drives the two drive rollers 809 to rotate in opposite directions, thereby driving the two extrusion belts 802 to rotate in opposite directions. On the central shaft of the other drive roller 809, separate retaining sleeves 822 are fitted at both ends of the drive roller 809 and fixed with screws to facilitate adjustment of the axial position of the drive roller 809 on this central shaft, ensuring that the two drive rollers 809 are aligned with each other.

[0112] A proximity switch 815 is mounted on the machine body 1 on the driven pulley side of the synchronous belt mechanism 819 via a switch bracket 814. A cross-shaped switch baffle 821 is fixed to one end of the central shaft 810 of one of the driving rollers 809 by screws to trigger the proximity switch 815, thereby controlling the position reset of the servo motor 817 when the machine stops. A bearing seat 813 is mounted on the central shaft 810 of one of the driving rollers 809 near the driven pulley of the synchronous belt mechanism 819 via a bearing, and is mounted on the machine body 1 through the bearing seat 813 to assist in supporting the central shaft.

[0113] During operation, the servo motor 817 of the first power source is started by the controller. The synchronous belt mechanism 819 drives the central shaft of one of the drive rollers 809 to rotate at a low speed. Through the gear pair 820, the two drive rollers 809 rotate in opposite directions, thereby driving the two extrusion belts 802 to rotate in opposite directions. By adjusting the eccentric direction of the adjusting shaft 807, the gap between the two extrusion belts 802 can be adjusted by the tensioning roller 805. This allows the material accumulated inside the cheese slice packaging to be separated by the extrusion belts 802, that is, the material at the corresponding horizontal sealing position on the cheese slice packaging is squeezed out to facilitate subsequent horizontal sealing.

[0114] like Figures 6-9As shown, the horizontal sealing device 2 includes a support cube 201 fixed to the front of the machine body 1. A primary horizontal sealing assembly 203 and a secondary horizontal sealing assembly 202, arranged vertically, are mounted on the support cube 201. Both the primary and secondary horizontal sealing assemblies 203 and 202 include a drive shaft 211 and a driven shaft 213, respectively arranged side-by-side on the support cube 201 via two sets of bearings 228. A sealing sleeve 207 is keyed to one end of the drive shaft 211, and a heating sleeve 216 is keyed to one end of the driven shaft 213. The sealing sleeve 207... Sealing blocks 206 are evenly distributed around the outer circumference of the heating sleeve 216. Multiple electric heating tubes 225 are evenly inserted around the circumference of the heating sleeve 216. In this embodiment, four electric heating tubes are used as an example. Rectangular bosses 2161 are evenly distributed around the outer circumference of the heating sleeve 216. The rectangular bosses 2161 correspond to and fit with the sealing blocks 206 one by one to achieve primary and secondary horizontal sealing of the packaging material. Bearing seats 210 are fixed on one side of the supporting cube 201 at the positions corresponding to the active shaft 211 and the driven shaft 213, respectively. Radial bearings are also installed between the active shaft 211 and the driven shaft 213 and the bearing seats 210, respectively. The sealing sleeve 207 and heating sleeve 216 have approximately square cross-sections. Rectangular grooves are provided at the four corners of the square cross-section corresponding to the outer edge of the sealing sleeve 207. Preferably, four sealing blocks 206 are embedded in these rectangular grooves and fixed by set screws 208 on the sealing sleeve 207. A positioning plate 209 is keyed onto the drive shaft 211 near the support cube 201. The sealing sleeve 207 is fixed to one side of the positioning plate 209 by evenly distributed screws to achieve the installation and positioning of the sealing sleeve 207. Limiting plates 215 are respectively fitted onto the driven shaft 213 at both ends of the heating sleeve 216. The limiting plates 215 are connected to the heating sleeve 216 by evenly distributed screws. The sleeve 216 is fixedly connected. Four blind holes and four screw holes are evenly distributed around the circumference of one of the limiting plates 215, and four through holes are evenly distributed around the circumference of the other limiting plate 215. The two ends of the electric heating tube 225 are respectively inserted into the corresponding blind holes and through holes, and are positioned by the set screw 217 screwed into the screw hole. A spacer 226 is sleeved on the inner side of the limiting plate 215 located at the inner end of the heating sleeve 216 on the driven shaft 213. The spacer 226 is inserted into the bearing mounting hole on the support cube 201 and connected to the driven shaft 213 by a key. The spacer 226 is connected to the mounting sleeve 227, which is connected to the driven shaft 213 by a key and is used to install the bearing 228, by screws to realize the axial positioning of the heating sleeve 216.

[0115] A shaft head 224 is fitted at one end of the drive shaft 211 and the driven shaft 213 with a small clearance fit and fixed with an internal hexagon screw. The two shaft heads 224 pass through and are mounted on a connecting plate 223 through bearings; this ensures that the gap between the rectangular boss 2161 and the two ends of the sealing block 206 is consistent. The sealing block 206 is made of nylon material. The drive shaft 211 of the primary horizontal sealing assembly 203 and the driven shaft 213 of the secondary horizontal sealing assembly 202 are vertically opposite each other.

[0116] Four wiring grooves are evenly distributed along the circumference of the driven shaft 213 of the primary horizontal sealing assembly 203 and the secondary horizontal sealing assembly 202. Conductive slip rings 212 are installed at the other end of the driven shaft 213. The fixed rings of the two conductive slip rings 212 are connected to each other by a connecting plate 221 to facilitate the external power supply of the electric heating tube 225. A textured pattern is machined on the rectangular boss 2161 on the outer edge of the heating sleeve 216 of the secondary horizontal sealing assembly 202 to improve the sealing firmness.

[0117] Two fifth power sources are installed at the rear of the machine body 1 via motor brackets 218. The fifth power source is composed of a servo motor 220 and a reducer 219, and its output end is connected to the other end of the drive shaft 211 and driven shaft 213 of the corresponding primary horizontal sealing component 203 and secondary horizontal sealing component 202 through three gears 214 meshing in sequence. It is used to drive the drive shaft 211 and driven shaft 213 of the primary horizontal sealing component 203 and secondary horizontal sealing component 202 to rotate in opposite directions at the same time.

[0118] A photoelectric switch 204 is mounted on the motor bracket 218 via a switch bracket 205. A switch baffle 222 is fixed to the gear side of the output end of the reducer 219 by screws. This baffle is used to trigger the photoelectric switch 204 and send a signal to the controller to control the position reset of the servo motor 220.

[0119] During operation, the controller simultaneously starts the servo motor 220 of the fifth power source, driving the drive shaft 211 and driven shaft 213 of the primary horizontal sealing assembly 203 and the secondary horizontal sealing assembly 202 to rotate in opposite directions. This, in turn, drives the sealing sleeve 207 and the heating sleeve 216 to rotate in opposite directions. The packaging material after passing through the extrusion device 8 passes between the sealing sleeve 207 and the heating sleeve 216. By the one-to-one correspondence between the sealing block 206 and the rectangular boss 2161 during the rotation of the sealing sleeve 207 and the heating sleeve 216, the packaging material can be sealed horizontally twice. The primary horizontal sealing assembly 203 can repeatedly squeeze out any parts that were not completely squeezed out by the extrusion device 8, and then the secondary horizontal sealing assembly 202 performs a secondary horizontal seal.

[0120] A cooling device 4 is provided at the lower front end of the machine body 1 to cool the cheese slices after they have been horizontally sealed. Figures 12-15As shown, the cooling device 4 includes a rectangular water tank 401, which is formed by connecting a frame and a trough plate fixed in the frame. A water inlet connector 418 and a water outlet connector 419 are respectively provided on the bottom surface of the water tank 401 near its two ends. A rotatable floating roller and a fixed roller are respectively installed in the water tank near its two ends. Multiple retaining rings 410 are evenly distributed and fixed on the floating roller and the fixed roller along their axial direction. The floating roller and the fixed roller form multiple slots through the retaining rings 410, which are used to separate the cheese slices and wrap them between the floating roller and the fixed roller.

[0121] The floating roller 408 and the fixed roller 402 are respectively mounted on the corresponding central shafts by bearings. The central shaft of the fixed roller 402 is inserted into the water tank 401 and both ends are fixed to the water tank 401 by an L-shaped plate frame 403.

[0122] A suspension rod 406 is fixedly supported on the frame of the water tank 401 above the floating roller 408 by a pair of T-shaped supports 404. The two ends of the central shaft of the floating roller 408 are respectively fixed to a swing arm 407. The upper ends of the two swing arms 407 are respectively mounted on the suspension rod 406 via bearings. A top block 405 is fixed to one side of the support 404 by screws. A set screw is screwed into the top block 405 and presses against the corresponding swing arm 407, used to push the floating roller 408 to tighten the cheese slices to be cooled. A perforated plate 409 is inserted inside the water tank 401 near the water outlet 419 to block foreign objects and prevent them from entering the external water pump.

[0123] Rotatable guide rollers 412 are respectively provided inside the water tank 401 on the inner side of the floating roller 408 and the fixed roller 402, for guiding cheese slices out of the fixed roller 402 and into the floating roller 408, respectively. The guide rollers 412 are mounted on their central shaft by bearings, and one end of their central shaft is fixed to a bracket 417 and fixed to a frame on one side of the water tank 401 by a set screw.

[0124] Two sets of support rollers 414 are provided inside the water tank 401 between the floating roller 408 and the fixed roller 402. Each set of support rollers 414 consists of three rollers, which are arranged vertically and spaced apart between two support roller brackets 413 to separate the cheese slices wound between the floating roller 408 and the fixed roller 402. The two support roller brackets 413 are respectively hung on the frames on both sides of the water tank 401 and fixed by set screws.

[0125] Inside the water tank 401, an isolation frame 411 is fixed on the inner side of the floating roller 408 and the fixed roller 402 respectively. The two ends of the isolation frame 411 are hung on the frames on both sides of the water tank 401 and fixed by top screws. The isolation frame 411 has multiple isolation slots provided by evenly distributed vertical plates, which correspond one-to-one with the slots, and are used to separate the cheese slices wrapped between the floating roller 408 and the fixed roller 402.

[0126] A feeding bracket 416 is provided on one side of the water tank 401 near the inside of the floating roller 408. The feeding bracket 416 is trough-shaped and arranged perpendicular to the axial direction of the floating roller 408. The feeding bracket 416 is fixed to the frame on one side of the water tank 401 by two hangers 415 and top screws. It is used to hold the cheese slices that enter and guide them into the floating roller 408.

[0127] In use, the water outlet connector 419 is connected to the inlet of a water pump through a pipeline, the water pump outlet is connected to the inlet of a plate heat exchanger, and the plate heat exchanger outlet is connected to the water inlet connector 418 through a pipeline. The water tank 401 is then filled with cooling water, thus forming a closed-loop cooling circulation device with the water tank 401 as the main body.

[0128] During operation, the cheese slices, after being horizontally sealed by the horizontal sealing device 2, fall into the water tank 401 from the upper middle part of the tank. They then pass through the feeding bracket 416 and the corresponding isolation grooves on the isolation frame 411 near the floating roller 408, entering the innermost slot of the floating roller 408. The cheese slices then repeatedly wind between the slots on the floating roller 408 and the fixed roller 402, finally exiting through the innermost slot on the fixed roller 402 and entering the subsequent drying device 3. As the cheese slices reciprocate between the floating roller 408 and the fixed roller 402, they are immersed in cooling water within the water tank 401, which lowers the temperature of the horizontally sealed cheese slices to approximately 20 degrees Celsius, thus achieving shaping.

[0129] like Figures 1-3 As shown, a lifting device 6 and a drying device 3 are arranged vertically on the left side of the horizontal sealing device 2 in front of the mounting plate 101 on the machine body 1, for lifting and drying the cheese slices respectively. Rotatable guide wheels 7 are mounted on the machine body 1 below the drying device 3 and above the lifting device 6 via axles and bearings, respectively. Rotatable limiting rollers 21 are mounted on one side of the guide wheels 7, for guiding the cheese slices cooled by the cooling device 4 into the drying device 3, and guiding the cheese slices output by the lifting device 6 into the subsequent horizontal cutting device 5.

[0130] like Figure 10 and Figure 11As shown, the air-drying device 3 includes a housing 301, which is fixed to a mounting plate and has a door on the front. Rectangular elongated holes are provided on the top and bottom surfaces of the housing 301 for cheese slices to enter and exit. Three pairs of inclined air nozzles 302 are symmetrically arranged in the lower part of the housing 301 along the vertical direction. The air nozzles 302 are fixed to the mounting plate 101 by brackets and have long, flat air outlets for connecting compressed air to dry the water droplets on the cheese slices. Two pairs of vertically arranged air-blowing boxes 303 are symmetrically arranged in the upper part of the housing 301. One end of each air-blowing box is closed, and the other end is connected to an air inlet pipe 305. The air inlet pipe 305 passes through the mounting plate 101 on the body 1 and connects to the air inlet pipeline. Each pair of air-blowing boxes 303 has corresponding strip-shaped air outlets 306 on opposite sides for connecting an external fan to further dry the water droplets on the cheese slices. A pair of rotatable export rollers 304 are provided at the rectangular elongated hole on the top surface of the box 301 for exporting cheese slices.

[0131] like Figure 48 As shown, the lifting device 6 includes two sets of belt conveyor mechanisms 601 arranged symmetrically in the vertical direction for clamping and lifting cheese slices upwards; the driving rollers and driven rollers of the two sets of belt conveyor mechanisms 601 are respectively mounted on two support seats 602 arranged vertically via axles and bearings, and the two support seats 602 are respectively fixed in front of the mounting plate 101 of the machine body 1; a sixth power source 604 is fixed behind the mounting plate 101 of the machine body 1 via a motor bracket 603. The sixth power source 604 is composed of a servo motor and a reducer.

[0132] like Figures 16-27 As shown, a cross-cutting device 5 is provided on the machine body 1 at the end away from the unwinding mechanism. The cross-cutting device 5 includes a mounting plate frame 501 fixed on the machine body 1. From top to bottom, a feeding mechanism 505, a cross-cutting mechanism 504, a discharging mechanism 503, and a breaking mechanism 502 are arranged on one side of the mounting plate frame 501 to achieve cross-cutting and breaking of the cheese slices.

The fixed belt conveyor mechanism 513 includes two mounting plates 516 connected to each other by a connecting plate 526 and two connecting rods 524. One mounting plate 516 is fixed to one side of the mounting plate frame 501 by bolts. Between the two mounting plates 516, a driving roller 523 and two driven rollers 527 arranged in a triangle are installed by roller shafts and bearings respectively. A left conveyor belt 525 is wound around the driving roller 523 and the driven rollers 527 and rests against one side of the connecting plate 526. A pressure roller 528 is installed between the two mounting plates 516 by roller shafts and bearings. The two ends of the roller shaft are inserted into and fixed by screws in the slots on the two mounting plates 516 to press the left conveyor belt 525. A bearing end cap 515 is fixed on the outer side of the mounting plate 516 away from the mounting plate frame 501, corresponding to one end of the driving roller 523.

[0134] The floating belt conveyor mechanism 514 includes two base plates 518 connected to each other by two connecting rods 524, and two movable plates 517 connected to each other by a connecting plate 526. The two movable plates 517 are respectively located between the two base plates 518 and the two mounting plates 516 that fix the belt conveyor mechanism 513. One base plate 518 is fixed to one side of the mounting plate frame 501. Guide blocks 530 are respectively fixed to the middle part of one side of the two base plates 518 by screws. The outer ends of the guide blocks 530 are respectively inserted into the sliding grooves in the middle of the movable plates 517 through clearance fit. Two pressure springs 519 arranged vertically are provided between the two base plates 517. A drive roller 523 and two pressing rollers 528 arranged vertically are installed between the two base plates 518 via roller shafts and bearings. Two passive rollers 527 arranged vertically are installed between the two movable plates 517 via bearings. A right conveyor belt 529 is wound around the drive roller 523 and the two passive rollers 527 and rests against the side of the corresponding connecting plate 526. The pressing rollers 528 press on the right conveyor belt 529. A bearing end cap 515 is fixed on the outer side of the base plate 518 away from the mounting frame 501, corresponding to one end of the drive roller 523.

[0135] A connecting plate 520 is fixedly connected between the bearing end caps 515 of the fixed belt conveyor mechanism 513 and the floating belt conveyor mechanism 514 by screws to improve the stability of the structure. This allows the right conveyor belt 529 of the floating belt conveyor mechanism 514 to adhere to the left conveyor belt 525 of the fixed belt conveyor mechanism 513 under the action of the pressure spring 519, thereby tightly clamping the cheese slices and feeding them into the lower cross-cutting mechanism 504. A seventh power source 508 is mounted behind the mounting plate on the machine body 1 via a motor bracket 509. The power source 508 is composed of a servo motor and a reducer. One end of the drive roller 523 of the fixed belt conveyor mechanism 513 and the floating belt conveyor mechanism 514 passes through the mounting plate frame 501 and is connected to the drive shaft 522 through the bushing. The output end of the seventh power source 508 is connected to the drive shaft 522 connected to one end of the drive roller 523 of the fixed belt conveyor mechanism 513 and the floating belt conveyor mechanism 514 through the synchronous belt mechanism 521, which is used to drive the left conveyor belt 525 and the right conveyor belt 529 to run in opposite directions at the same time.

[0136] like Figures 25-27 As shown, the cross-cutting mechanism 504 includes two support plates 533. One support plate 533 is fixed to one side of the mounting frame 501 by bolts. The two support plates 533 are connected to each other at one end by a connecting block 538. The inner side of the connecting block 538 is arc-shaped. A rotatable cutter roller 539 and a support roller 534 are mounted side by side between the two support plates 533 via bearings. Four rectangular grooves are evenly distributed along the circumferential direction on the outer edge of the middle part of the cutter roller 539. A cutter 543 is clamped in each rectangular groove by a pressure plate 542. The cutter 543 is clamped between the pressure plate 542 and the rectangular groove. Between the inner walls of one side of the groove, three screw holes are evenly distributed on the other side and bottom surface of each pressure plate 542 on the cutter roller 539, and adjusting screws 544 are screwed in. The inner end of the adjusting screw 544 rests against the other side and bottom surface of the corresponding pressure plate 542 to facilitate the adjustment of the position and parallelism of the cutter 543. Positioning discs 537 are respectively sleeved on both ends of the middle part of the cutter roller 539 and fixed with screws to realize the axial positioning of the pressure plate 542 and the cutter 543. Two notches are symmetrically provided on one side of the blade of each cutter 543 to form two connecting ribs between two adjacent cheese slices when cutting horizontally. Bearing seats 540 are inserted into and fixed with screws at both ends of the cutter roller 539 on the outer side of the two support plates 533. The two ends of the cutter roller 539 are installed in the corresponding bearing seats 540 through bearings to facilitate quick disassembly and maintenance of the cutter 543. Slide grooves are opened at both ends of the support roller 534 on the outer side of the two support plates 533, and sliding seats 541 are installed in the slide grooves through sliding clearance. The two ends of the support roller 534 are installed in the corresponding sliding seats 541 through bearings. A sealing strip 532 is fixed on one end of the slide groove on the two support plates 533. A pressure spring 531 is provided between the sealing strip 532 and the corresponding sliding seat 541 to make the support roller 534 elastically abut against the outer edge of the cutter roller 539 to cut the cheese slice and protect the cutter 543.

[0137] A second power source 510 is installed behind the mounting plate of the machine body 1 via a support sleeve 535. The second power source 510 is composed of a servo motor and a reducer. A connecting shaft 536 is installed inside the support sleeve 535 via a bearing. One end of the connecting shaft 536 is inserted into the output shaft of the reducer and connected by a key, and the other end is inserted into the corresponding end of the cutter roller 539 and connected by a key.

[0138] like Figures 16-19 As shown, the discharge mechanism 503 has the same structure as the feeding mechanism 505 and shares a power source with the feeding mechanism 505. That is, the two drive rollers of the discharge mechanism 503 are also connected to the output end of the reducer of the seventh power source 508 through the transmission shaft and synchronous belt mechanism 546 connected to one end of it, so as to drive the left and right conveyor belts of the discharge mechanism 503 to run in opposite directions at the same time.

[0139] The pull-off mechanism 502 includes two fixed belt conveyor mechanisms 5021 arranged symmetrically on the left and right. The fixed belt conveyor mechanism 5021 has a basically the same structure as the fixed belt conveyor mechanism 513 in the feeding mechanism 505. The difference is that the two mounting plates of the fixed belt conveyor mechanism 5021 on the right side are connected to each other by two connecting rods 524, and no connecting plate is provided. In addition, the operating speed of the two fixed belt conveyor mechanisms 5021 is slightly higher than the belt running speed of the discharge mechanism.

[0140] An eighth power source 511 is mounted behind the mounting plate on the body 1 via a motor bracket 545. The eighth power source 511 is composed of a servo motor and a reducer. The output end of the reducer is connected to the two drive rollers of the pull-off mechanism 502 via a synchronous belt mechanism 512, which is used to drive the two conveyor belts of the pull-off mechanism 502 to run in opposite directions simultaneously.

[0141] On the mounting plate 501, above the feeding mechanism 505, two through-beam photoelectric switches 506 are symmetrically mounted on both sides via brackets 507. These switches are used to detect the horizontal sealing position of the cheese slice and send a signal to the controller of the cheese slice filling machine, thereby controlling the servo motor of the second power source 510 to start, ensuring that the cutter 543 of the horizontal cutting mechanism 504 cuts the cheese slice at the horizontal sealing position.

[0142] The working principle of the transverse cutting device 5 is as follows: The transverse sealing position of the cheese slice is detected by the through-beam photoelectric switch 506, and a signal is sent to the controller of the cheese slice filling machine, thereby controlling the start of the servo motors of each power source. After the servo motor of the seventh power source 508 starts, it drives the fixed belt conveyor mechanism 513 and the floating belt conveyor mechanism 514 of the feeding mechanism 505 to rotate simultaneously in opposite directions, clamping the cheese slice after the filling is transversely sealed and feeding it into the transverse cutting mechanism 504; after the servo motor of the second power source starts, it drives the cutter roller 539 and the support roller 534 to rotate simultaneously in opposite directions. The cutter 543 on the cutter roller 539, in cooperation with the support roller 534, can partially cut the transverse sealing position between two adjacent cheese slices, leaving two connecting ribs; the seventh... When the power source 508 starts, it drives the fixed belt conveyor and the floating belt conveyor of the discharge mechanism 503 to run in opposite directions at the same speed as the feeding mechanism 505, and feeds the transversely cut cheese slices into the tearing mechanism 502 below; after the servo motor of the eighth power source 511, it drives the two conveyor belts of the tearing mechanism 502 to run in opposite directions at a speed slightly higher than the running speed of the left and right conveyor belts of the discharge mechanism 503, thereby tearing the two connecting ribs of the cheese slices and pulling the adjacent cheese slices apart and outputting them downwards.

[0143] The cheese slice filling machine has a programmable controller inside the machine body 1 and is connected to a human-machine interface 18. The human-machine interface 18 is located at one end of the machine body 1 and is used to realize the automatic control and parameter setting of the whole machine.

[0144] The working principle of this cheese slice filling machine is as follows: 1. The cheese slice packaging rolls to be used are respectively installed on two unwinding shafts 14. The outer end of one of the packaging rolls passes through the corresponding first steering roller, a pair of clamping rollers, and four second steering rollers in sequence into the tensioning mechanism 13. Then, it passes through three third steering rollers 1303, two floating steering rollers 1305, and three fourth steering rollers in the tensioning mechanism 13 in sequence into the forming and unloading device 11. 2. The packaging material entering the forming and feeding device 11 passes through the gap between the forming sleeve of the forming device 1117 and the forming support 1119, causing the two sides of the packaging material to overlap and form a flat tube shape. After being connected to an external power source by the electric heating tube 1125, the longitudinal sealing block 1101 is heated. Under the action of the counterweight sleeve, the longitudinal sealing block 1101 is pressed against the overlapping edge of the packaging material by the pressure strip 24, so that the packaging material is longitudinally sealed. At the same time, the heated liquid cheese is introduced into the longitudinally sealed packaging material through the external injection pump connected to the feeding pipe 1116.

[0145] 3. After being longitudinally sealed, the cheese slice packaging material adheres tightly to the long rod of the swing arm 1001 and enters the thickness adjustment device 9. Before entering the thickness adjustment device 9, the material will form a certain amount of accumulation, which will push the swing arm 1001 to drive the transmission shaft 1002 to rotate clockwise. The more material accumulates, the greater the angle of rotation of the swing arm 1001 and the transmission shaft 1002. At the same time, the transmission shaft 1002 drives the central shaft of the rotary encoder 1010 to rotate through the synchronous belt mechanism, so that the rotary encoder 1010 outputs a signal to the controller of the cheese slice filling machine. The controller controls the flow rate of the liquid injection pump connected to the longitudinal sealing and feeding device according to the received signal from the rotary encoder 1010, thereby controlling the material level in the cheese slice packaging material.

[0146] 4. The cheese slices entering the thickness adjustment device 9 are started by the servo motor of the third power source 901. The synchronous belt mechanism 902 drives the reference roller 906 and the adjustment roller 907 to rotate in opposite directions at the same time, thereby compressing the thickness of the cheese slices passing between the reference roller 906 and the adjustment roller 907 and pulling the cheese slices downward, so that the cheese slice packaging material after feeding forms a thin strip and enters the extrusion device 8. 5. The first power source of the extrusion device 8 is started, which drives the two extrusion belts 802 to rotate in opposite directions. The rectangular protrusions 8021 on the two extrusion belts 802 can continuously squeeze out the material at the corresponding horizontal sealing position on the cheese slice packaging material, so as to facilitate the subsequent horizontal sealing.

[0147] 6. The cheese slices extruded by the extrusion device 8 enter the horizontal sealing device 2, passing between the sealing sleeve 207 and the heating sleeve 216. Simultaneously, the controller starts the servo motor 220 of the fifth power source, driving the drive shaft 211 and driven shaft 213 of the primary horizontal sealing assembly 203 and the secondary horizontal sealing assembly 202 to rotate in opposite directions. This causes the sealing sleeve 207 and the heating sleeve 216 to rotate in opposite directions. During rotation, the sealing block 206 and the rectangular boss 2161 correspond and adhere one-to-one, achieving two horizontal seals on the packaging material. The primary horizontal sealing assembly 203 can repeatedly extrude any areas not completely extruded by the extrusion device 8, and then the secondary horizontal sealing assembly 202 performs a second horizontal seal.

[0148] 7. After the cheese slice packaging is horizontally sealed, it enters the water tank below. As the cheese slice moves back and forth between the floating roller 408 and the fixed roller 402 in the water tank, it is immersed in the cooling water in the water tank 401, which can reduce the temperature of the horizontally sealed cheese slice to about 20 degrees Celsius and achieve shaping.

[0149] 8. After the cheese slices are shaped, they enter the drying device 3 through the guide wheel 7 below the drying device 3. After the water droplets on the cheese slices are dried by the drying device 3, they enter the cross-cutting device 5 through the lifting device 6 and the guide wheel 7 above.

[0150] 9. The cheese slices entering the cross-cutting device 5 are fed through the feeding mechanism. The controller starts the seventh power source 508, which drives the fixed belt conveyor mechanism 513 and the floating belt conveyor mechanism 514 to rotate in opposite directions, clamping the cheese slices and feeding them into the cross-cutting mechanism below. At the same time, the second power source 510 drives the cutter roller 539 to rotate through the connecting shaft 536. The cutter 543 on the cutter roller 539 cooperates with the support roller 534 to achieve continuous cross-cutting of the cheese slices. Since two notches are symmetrically provided on one side of the blade of each cutter 543, two connecting ribs will be formed at the cut between two adjacent cheese slices during cross-cutting.

[0151] 10. After being transversely sliced, the cheese slices enter the discharge mechanism. The seventh power source 508 simultaneously drives the fixed belt conveyor and the floating belt conveyor of the discharge mechanism 503 to run in opposite directions and at the same speed as the feeding mechanism 505, sending the transversely sliced ​​cheese slices into the tearing mechanism 502 below. At the same time, the servo motor of the eighth power source 511 starts, driving the two conveyor belts of the tearing mechanism 502 to run in opposite directions at a speed slightly higher than the speed of the left and right conveyor belts of the discharge mechanism 503, thereby tearing the two connecting ribs of the cheese slices and pulling the adjacent cheese slices apart to output them downward to the stacking device below for stacking.

[0152] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, any modifications, equivalent substitutions, or improvements made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
