Description

Technical Field

[0001] This invention relates to a stuffed food forming machine, and more particularly to a device that can automatically extrude edible fillings into strips and automatically wrap them with edible outer skin. Prior Technology

[0002] To increase production, modern food manufacturing typically employs specialized food processing machinery. This machinery uses conveyor belts to transport food to different processing locations, making the conveyor belts prone to food residue buildup, which is often difficult to clean. Furthermore, the need for cutting during food processing can generate significant noise from the metal-to-metal collisions of the cutting blades. Summary of the Invention

[0003] Therefore, the present invention proposes a stuffed food forming machine, comprising: A first support includes a first side portion and a second side portion; A first conveyor belt device, coupled to a first support and located between a first side and a second side, includes a fixed portion and a movable portion pivotally connected to the fixed portion. A first conveyor belt is wound around the outer sides of the fixed portion and the movable portion. The movable portion is pivotable relative to the fixed portion to a conveying position and a cleaning position. When the movable portion is in the conveying position, the first conveyor belt abuts against an upper surface of both the fixed portion and the movable portion. When the movable portion is in the cleaning position, the first conveyor belt is spaced apart from the upper surfaces of both the fixed portion and the movable portion. The first conveyor belt device is suitable for transporting an outer skin. A filling-forming device, combined with the first support and located on the first side and above the first conveyor belt device, is adapted to extrude edible lump filling into a strip of filling and stack it on the outer skin; A covering device, combined with the first conveyor belt device, the covering device includes a rotating wrapper roller, the wrapper roller being configured to abut against the surface of the outer wrapper, the wrapper roller rotating so that the strip filling is completely covered inside the outer wrapper when the first conveyor belt device moves the outer wrapper and the strip filling.

[0004] The movable part of the first conveyor belt device can be pivoted to the cleaning position so that the first conveyor belt is separated from the conveyor support, making cleaning and / or maintenance of the first conveyor belt device quite convenient.

[0005] In one embodiment, the stuffed food forming machine, wherein the first conveyor belt device further comprises: A mounting bracket is fixedly connected to the fixing part, the mounting bracket including two rails and two ears adjacent to the two rails; A drive wheel is rotatably coupled within the mounting frame and abuts against the first conveyor belt; rotation of the drive wheel drives the first conveyor belt to rotate around the fixed portion and the movable portion. A first conveyor belt driver is fixed on the mounting frame, and the first conveyor belt driver is connected to the drive wheel to rotate. A rotatable first tension wheel includes two tail ends, the two tail ends being movably engaged with two tracks of the mounting frame, the first tension wheel being able to press against the first conveyor belt; Two abutting members are screwed to the two ears and abut against the two tail ends. The rotation of the two abutting members changes the position of the first tension wheel to adjust the tension of the first conveyor belt. When the first tension wheel abuts against the first conveyor belt, the movable part remains in the conveying position. When the first tension wheel relaxes the first conveyor belt, the movable part is allowed to pivot from the conveying position to the cleaning position.

[0006] The movement of the first tension wheel of the first conveyor belt device can adjust the tension of the first conveyor belt. When the tension of the first conveyor belt is large, the movable part can remain in the conveying position. When the tension of the first conveyor belt is small, the movable part can easily pivot from the conveying position to the cleaning position, making cleaning and / or maintenance of the first conveyor belt device quite convenient.

[0007] In one embodiment, the first conveyor belt device of the stuffed food forming machine further includes: The movable part further includes two fixing members and two guide grooves formed at one end. The fixing part includes two pivots. The two pivot grooves of the movable part are pivotally connected to the two pivots. The two fixing members pass through the two guide grooves and are screwed to the fixing part. When the two fixing members are locked, the movable part is clamped and positioned.

[0008] When the movable part is in the clean position, the locking of the two fixing members can keep the movable part in the clean position, making cleaning and / or maintenance of the first conveyor belt device quite convenient.

[0009] In one embodiment, the stuffed food forming machine further includes: A feeding unit is constructed to extrude lumpy filling into strip-shaped filling; A feed hopper is connected in communication with the feed unit; A filling driver is coupled to the first support; An extrusion assembly is rotatably housed within the feed hopper. The extrusion assembly includes a rotating shaft and a feed member fixedly connected to the rotating shaft. When the extrusion assembly rotates, the feed member extrudes the lumpy filling into the feed unit. A fitting sleeve, which engages with the filling driver, the fitting sleeve comprising a fitting groove formed on an outer surface; A connector, rotatably sleeved with the extrusion assembly, is provided with a through hole corresponding to the fitting groove; A fitting is movably engaged with the perforation; A limiting ring, movably sleeved on the outside of the connector, includes an inner annular groove formed on its circumferential surface. When the limiting ring moves to a position where the inner annular groove is spaced apart from the fitting along the axial direction of the extrusion assembly, the fitting engages with the fitting groove, ensuring that the axial thrust generated by the extrusion assembly during operation does not cause the connector to separate from the fitting sleeve. When the limiting ring is displaced to a position where the inner annular groove aligns with the fitting, the fitting is allowed to disengage from the fitting groove, causing the connector to disengage from the fitting sleeve.

[0010] The extrusion assembly is rotatably connected to the fitting sleeve via the connector and the limiting ring. When the extrusion assembly is subjected to a reaction force along the axis parallel to the extrusion assembly, the limiting ring will not move, making it difficult for the extrusion assembly to separate from the fitting sleeve during operation, thus ensuring that the filling device can operate normally.

[0011] In one embodiment, the stuffed food forming machine further includes: A cutting device includes a tool driver fixed to a second side of a first support, the cutting device further including a tool that is displaced by the tool driver; A support frame, which is coupled to the second side of the first bracket and aligned with the cutter, includes a resilient buffer that is compressed when the cutter moves toward the support frame.

[0012] The cutting device has an elastic buffer below the blade, so that the support frame can support the stuffed food when the blade cuts the stuffed food, so that the soft stuffed food can be cut reliably and the buffer can reduce the noise of the blade operation.

[0013] In one embodiment, the support frame of the stuffed food forming machine further includes: A first portion, movably coupled to a second side portion, the first portion allowing for adjustment of the distance between itself and the cutting tool; A second part is fixed on the first part, the second part including a slot, the buffer being fitted into the slot.

[0014] Two symmetrical support frames are fixed to the second side of the first bracket. The two support frames are screwed to two adjusting screws. The two adjusting screws abut against the bottom surface of the support frame. Rotating the two adjusting screws can finely adjust and position the support frame so that the support frame can be located at an appropriate height, making the process of cutting the stuffed food smoother.

[0015] In one embodiment, the stuffed food forming machine further includes: A support frame is attached to the second side portion, the support frame being located between the support frame and the cutting tool; An adjusting screw is screwed to the support frame and abuts against a bottom surface included in the first part. Rotating the adjusting screw presses against the support frame to change the distance between it and the tool.

[0016] In one embodiment, the stuffed food forming machine further includes: A second support: A second conveyor belt assembly is fixed to the second support and adjacent to the second side of the first conveyor belt assembly, and the cutting device is located between the first conveyor belt assembly and the second conveyor belt assembly; A shaping device is fixed on the second conveyor belt device, the shaping device including two shaping rollers adjacent to the second conveyor belt device, the two shaping rollers being configured to adjust a plurality of filled food products cut by the cutting device into the desired shape.

[0017] The two movable units of the second conveyor belt device can be pivoted to the maintenance position, so that the second conveyor belt is separated from the fixed unit and the upper surface of the two movable units, making the maintenance and cleaning of the second conveyor belt device easier.

[0018] In one embodiment, the stuffed food forming machine, the second conveyor belt device further includes: A fixing unit is fixed to the second bracket, the fixing unit further including a spaced-apart end; A movable unit, pivotally connected to the end of the fixed unit, the movable unit allowing pivoting relative to the fixed unit to a transport position and a maintenance position; A second conveyor belt is wound around the outside of the fixed unit and the movable unit. When the movable unit is in the transport position, the second conveyor belt is abutted against an upper surface of each of the fixed unit and the movable unit. When the movable unit is in the maintenance position, the second conveyor belt is separated from the upper surfaces of the fixed unit and the movable unit.

[0019] In one embodiment, the stuffed food forming machine further includes: A second tension wheel includes two tail sections, the fixing unit includes two channels and two lugs adjacent to the two channels, the two tail sections are movably engaged with the two channels, and the second tension wheel can press against the second conveyor belt; Two pressing units are screwed to the two lugs and abut against the two tail sections. The rotation of the two pressing units changes the position of the second tension wheel to adjust the tension of the second conveyor belt. When the second tension wheel presses against the second conveyor belt, the movable unit remains in the transport position. When the second tension wheel releases the second conveyor belt, the movable unit is allowed to pivot from the transport position to the maintenance position.

[0042] The movable part 36 forms a pivot groove 48 on each side of one end of the two pivot parts 40. The movable part 36 further includes two guide grooves 50 adjacent to the two pivot grooves 48. A movable roller 46 is rotatably provided on the symmetrical side of the movable part 36 and the two pivot grooves 48.

[0043] The two pivot grooves 48 of the movable part 36 are pivotally connected to the two pivots 40 of the fixed part 34. The two fixing members 42 pass through the two guide grooves 50 and are screwed to the fixed part 34. In the state where the two fixing members 42 are loose, the movable part 36 is allowed to pivot to a conveying position and a cleaning position. When the movable part 36 is in the conveying position, an upper surface of the movable part 36 is tangent to and parallel to an upper surface of the fixed part 34 (as shown in Figures 1, 7, and 13). When the movable part 36 is in the cleaning position (as shown in Figure 16), the upper surface of the movable part 36 is not parallel to the upper surface of the fixed part 34.

[0044] The first conveyor belt device 30 further includes a mounting frame 52 fixed below the fixing part 34. The mounting frame 52 includes two tracks 56 formed on two symmetrical sides and two mounting holes 54 communicating with the two tracks 56. The mounting frame 52 further includes two ears 58 formed on the two sides and adjacent to the two tracks 56.

[0045] A drive wheel 60 is rotatably disposed within the mounting frame 52. A first conveyor belt driver 62 is fixedly disposed on the outer side of the mounting frame 52. The first conveyor belt driver 62 may be, but is not limited to, being an electric motor. The first conveyor belt driver 62 is coupled to the drive wheel 60, enabling the first conveyor belt driver 62 to drive the drive wheel 60 to rotate. The first conveyor belt device 30 further includes a first tension wheel 66. The first tension wheel 66 further includes two tail ends 68 extending outward from two outer ends. The first tension wheel 66 moves from the mounting hole 54 into the mounting frame 52, and the two tail ends 68 are movably coupled to two tracks 56. The two ears 58 are screwed to two abutment members 64. The two abutment members 64 may be, but is not limited to, being screws. The ends of the two abutment members 64 abut against the two tail ends 68 of the first tension wheel 66. Rotating the two abutment members 64 can cause the first tension wheel 66 to displace along the two tracks 56.

[0046] The outer periphery of the conveying bracket 32 ​​is rotatably connected to a first conveyor belt 70. The first conveyor belt 70 is attached to the inlet roller 44, the movable roller 46, the drive wheel 60, and the first tension wheel 66. The rotation of the drive wheel 60 is linked to the rotation of the first conveyor belt 70 around the conveying bracket 32.

[0047] The fixed part 34 of the first conveyor belt device 30 is fixedly connected to the first bracket 20, the entry end 37 is adjacent to the first side part 22, and the movable part 36 is adjacent to the second side part 26.

[0048] The stuffed food forming machine 10 further includes a set of rolling devices 273 fixed to the outside of the first side 22 of the first support 20. The rolling devices 273 are used to pivotally connect with two edible strip-shaped outer skins 277. The two strip-shaped outer skins 277 are preferably rolled into a cylindrical shape and pivotally connected to the rolling devices 273. The ends of the two strip-shaped outer skins 277 are attached to the surface of the first conveyor belt 70. When the first conveyor belt 70 rotates, the two strip-shaped outer skins 277 can be transported by the first conveyor belt 70 and laid flat on the first conveyor belt 70.

[0049] The stuffed food forming machine 10 further includes a filling device 72, which includes a feeding unit 72B and a feeding hopper 72A connected in communication with the feeding unit 72B. The feeding unit 72B includes a distribution pipe 72C and two discharge pipes 72D connected in communication with the distribution pipe 72C. The two discharge pipes 72D face the first conveyor belt 70. The feeding unit 72B is fixed to the upper end 24 of the first side 22 of the first support 20. The feeding unit 72B may, but is not limited to, have internally driven and rotatable extrusion rollers that can extrude an edible lump of filling 275A into the distribution pipe 72C and extrude it into two strips of filling 275B (as shown in Figure 10) by the discharge pipes 72D, which abut against the two outer skins 277.

[0050] The filling device 72 further includes a filling driver 74 located above the feed hopper 72A. The filling driver 74 is coupled to a transmission member 151, which is rotatably coupled to a fitting sleeve 137. The fitting sleeve 137 includes two symmetrical fitting grooves 139.

[0051] The feed hopper 72A rotatably houses an extrusion assembly 76, which includes a rotating shaft 78 with a first end 80 and a second end 82. The extrusion assembly 76 further includes a feed member 84 rotatably coupled with the rotating shaft 78. The feed member 84 is helical and located between the first end 80 and the second end 82. The feed member 84 is conical, with the side closer to the first end 80 being larger than the side closer to the second end 82. The second end 82 of the rotating shaft 78 is rotatably coupled to the feed unit 72B.

[0052] The extrusion assembly 76 further includes a support arm 86 and a scraper 92. The support arm 86 includes an inner end 88 and an outer end 90. The inner end 88 of the support arm 86 is rotatably coupled with the rotating shaft 78. The inner end 88 is located between the first end 80 and the feed member 84.

[0053] The scraper 92 includes a connecting portion 94 and an extension arm 96 extending outward from the connecting portion 94. The scraper 92 is connected to the outer end 90 of the support arm 86, and the extension arm 96 abuts against the support arm 86. The scraper 92 is located between the first end 80 and the feed member 84 along an axial direction parallel to the extrusion assembly 76.

[0054] The first end 80 of the rotating shaft 78 is rotatably connected with a linkage 98, the linkage 98 having a non-circular transverse cross-section. The linkage 98 is rotatably connected with a connector 111, the connector 111 including a sleeve hole 115 extending through along an axial direction parallel to the rotating shaft 78. The connector 111 further includes two through holes 117 extending from its outer peripheral surface to communicate with and be symmetrical to the sleeve hole 115. The connector 111 also includes a limiting groove 113 recessed from its outer peripheral surface. The limiting groove 113 is located circumferentially around the axis of the connector 111 between the two through holes 117. Two fittings 119 are movably accommodated in the two through holes 117. The two fittings 119 may, but are not limited to, be made of steel balls.

[0055] A limiting ring 131 is movably fitted onto the outer side of the connector 111. A limiting member 135 protrudes inward from the limiting groove 113 corresponding to the limiting ring 131. The limiting ring 131 also includes an inner annular groove 133 formed on its inner circumferential surface. The limiting ring 131 is fitted around the outer periphery of the connector 111, and the limiting member 135 is movably accommodated in the limiting groove 113. The limiting member 135 cooperates with the limiting groove 113 to prevent the limiting ring 131 from separating from the connector 111 along the axis of the connector 111 towards the feed member 84.

[0056] Referring to Figures 3 and 7-9, the extrusion assembly 76 is housed within the feed hopper 72A. When the limiting ring 131 is located between the inner ring groove 133 and the two through holes 117 along an axial direction parallel to the extrusion assembly 76, the fitting sleeve 137 is allowed to be fitted into the sleeve hole 115 of the connector 111, so that the two through holes 117 are aligned with the two fitting grooves 139.

[0057] When the limiting ring 131 is displaced until the inner ring groove 133 is misaligned with each of the perforations 117 along the axial direction parallel to the extrusion assembly 76, the two fitting members 119 can only remain in the position of fitting with the two fitting grooves 139. Thus, the extrusion assembly 76 cannot move along the axial direction parallel to the extrusion assembly 76 to separate the connecting member 111 and the fitting sleeve 137. It can be understood that when the filling driver 74 operates, the transmission member 151, the fitting sleeve 137, the limiting ring 131, the two fitting members 119, the connecting member 111, and the extrusion assembly 76 rotate together. Furthermore, the outer end of the scraper 92 abuts against the inner circumferential surface of the feed hopper 72A.

[0058] The stuffed food forming machine 10 further includes two covering devices 153 fixed on both sides of the fixed part 34. Each covering device 153 includes a rotatable and conical rolling roller 155. The two rolling rollers 155 are attached to the two outer skins 277. Referring to Figure 11, when the first conveyor belt 70 moves the two outer skins 277 through the two rolling rollers 155, the two rolling rollers 155 rotate so that the two outer skins 277 cover the outer circumference of the two strip-shaped fillings 275B.

[0059] The stuffed food forming machine 10 includes a cutting device 157 disposed on the second side 26. The cutting device 157 includes a cutter driver 159 fixed to the top end 28 of the second side 26. The cutter driver 159 may be, but is not limited to, a pneumatic cylinder or a hydraulic cylinder. The cutter driver 159 is coupled to a cutter 171, so that when the cutter driver 159 operates, the cutter 171 can be displaced.

[0060] The cutting device 157 further includes a support frame 177 movably disposed inside the second side portion 26. The support frame 177 includes a first part 179 and a second part 195. The first part 179 includes a bottom surface 193 and a mating groove 191 recessed from one side. The first part 179 is movably mated to the inside of the second side portion 26 and close to the top end 28. The first part 179 is also adjacent to the movable part 36 of the first conveyor belt device 30.

[0061] The second part 195 is detachably coupled to the coupling groove 191. The second part 195 further includes a slot 196, in which a flexible buffer 197 is embedded. The buffer 197 is aligned with the cutter 171. Referring to Figures 12-13, when the cutter 171 moves downward to the bottom, it will press against the buffer 197.

[0062] The stuffed food forming machine 10 of the present invention further includes a second support 199, a second conveyor belt device 200, and two shaping devices 257. The second conveyor belt device 200 includes a fixed unit 211 and two movable units 231 pivotally connected to the fixed unit 211. The fixed unit 211 includes two mutually spaced ends 213. The fixed unit 211 further includes two channels 219 formed on two symmetrical sidewalls and two receiving holes 217 communicating with the two channels 219. The fixed unit 211 also includes two shaft joints 215 and two lugs 220 formed on the two sidewalls. The two channels 219 are located between the two receiving holes 217 and the two lugs 220. The two lugs 220 are located between the two channels 219 and the two shaft joints 215. The two shaft joints 215 are located between the two lugs 220 and one of the ends 213.

[0063] The two movable units 231 include two pivot grooves 233 and two guide grooves 235 formed at one end, and the two movable units 231 further include a movable roller 232 rotatably disposed at the other end. The two movable units 231 are respectively disposed at the two ends 213 of the fixed unit 211. That is, the fixed unit 211 is located between the two movable units 231. The two pivot slots 233 of the two movable units 231 are pivotally connected to the two shaft connections 215, so that the two movable units 231 can pivot relative to the fixed unit 211 to a transport position (as shown in Figures 7 and 13) and a maintenance position (as shown in Figure 17). When the two movable units 231 are in the transport position, the upper surfaces of the two movable units 231 and the fixed unit 211 are parallel to each other and aligned. When the two movable units 231 are in the maintenance position, the upper surfaces of the two movable units 231 are not parallel to the upper surface of the fixed unit 211.

[0064] The second conveyor belt device 200 also includes four locking units 216. Two of the locking units 216 may, but are not limited to, be made of bolts. Each of the four locking units 216 passes through a corresponding guide groove 235 and is screwed to the fixed unit 211. It can be understood that when the four locking units 216 are locked, the two movable units 231 will be clamped by the four locking units 216 and will not easily pivot.

[0065] The second conveyor belt device 200 includes a second tension wheel 237 and two pressing units 240. The second tension wheel 237 includes two tail sections 239 extending outward from two outer ends. The second tension wheel 237 is inserted into the fixing unit 211 through one of the two receiving holes 217. The two tail sections 239 are movably connected to the two channels 219. The two pressing units 240 may be, but are not limited to, being constructed with bolts. The two pressing units 240 are screwed to the two lugs 220 and abut against the two tail sections 239, and can therefore be disengaged. Rotating the two pressing units 240 can change the position of the second tension wheel 237.

[0066] The second conveyor belt device 200 further includes an assembly frame 250, a second conveyor belt driver 251, a connecting wheel 253, and a second conveyor belt 255. The assembly frame 250 is fixed below the fixed unit 211. The connecting wheel 253 is rotatably connected to the assembly frame 250. The second conveyor belt driver 251 may be, but is not limited to, an electric motor. The second conveyor belt driver 251 is fixed on the assembly frame 250 and can drive the connecting wheel 253 to rotate. The second conveyor belt 255 is wound around the outside of the fixed unit 211 and the movable unit 231. The two movable rollers 232, the second tension wheel 237, and the connecting wheel 253 abut against the surface of the second conveyor belt 255. The connecting wheel 253 drives the second conveyor belt 255 to rotate around the fixed unit 211 and the two movable units 231. The second tension wheel 237 changes position to adjust the tension of the second conveyor belt 255. It can be understood that when the tension of the second conveyor belt 255 is large, the two movable rollers 232 are not easy to pivot from the conveying position to the maintenance position.

[0067] Each of the two shaping devices 257 includes a shaping driver 259, which may, but is not limited to, being an electric motor. Each shaping device 257 also includes two shaping rollers 271 that are driven to rotate by the shaping driver 259. The two shaping drivers 259 are straddling the fixed unit 211 and staggered from each other, and each shaping roller 271 is adjacent to the second conveyor belt 255.

[0068] The technical features of the stuffed food forming machine 10 of the present invention have been described in detail. The operation of the stuffed food forming machine 10 will be further described below. Referring to Figures 7 and 10, firstly, two rolls of edible outer skin 277 are pivotally mounted on the rolling device 273. The ends of the two rolls of edible outer skin 277 are attached to the first conveyor belt 70. The operation of the first conveyor belt 70 can continuously spread each outer skin 277 flat on the first conveyor belt 70 and transport it in the direction of the second conveyor belt device 200. An edible ball-shaped filling 275A is put into the feed hopper 72A of the filling device 72. When the extrusion assembly 76 rotates, the spiral feed member 84 can push the filling 275A along the axial direction parallel to the extrusion assembly 76. The lumpy filling 275A is squeezed into the interior of the feeding unit 72B. Further referring to Figure 11, it is worth noting that when the extrusion assembly 76 presses the lumpy filling 275A, the extrusion assembly 76 will bear a reaction force along an axis parallel to the extrusion assembly 76 toward the filling driver 74. In this state, because the inner ring groove 133 of the limiting ring 131 is misaligned with the two perforations 117 and the two fittings 119, the two fittings 119 remain engaged with the two fitting grooves 139, preventing the extrusion assembly 76 from separating from the fitting sleeve 137. This further allows the lumpy filling 275A to be continuously squeezed into the feeding unit 72B.

[0069] It is worth mentioning that the lumpy filling 275A located in the feed hopper 72A may stick to or remain on the inner surface of the feed hopper 72A. When the extrusion assembly 76 rotates, the scraper 92 also rotates together, so the filling 275 that sticks to or remains on the inner surface of the feed hopper 72A can be scraped off by the scraper 92.

[0070] The filling in the feeding unit 72B is further squeezed into the distribution pipe 72C by the rollers in the feeding unit 72B and extruded into two strip-shaped fillings 275B on the surface of the two outer skins 277 by the two discharge pipes 72D. Thus, the two strip-shaped fillings and the two outer skins 277 are transported by the first conveyor belt 70 through the two covering devices 153. The two rolling rollers 155 of the two covering devices 153 are in contact with the surface of the two outer skins 277, so the rotation of the two rolling rollers 155 is through the two outer skins 277 covering the outer surface of the two strip-shaped fillings 275B to form two continuous long strip-shaped filled food products 279 (as shown in Figure 12).

[0071] Two consecutive elongated filled food items 279 continue to be transported by the first conveyor belt 70 to the cutting device 157. Referring to Figures 13-14, when the two consecutive elongated filled food items 279 move below the cutting device 157, the blade driver 159 pushes the blade 171 to move towards the support frame 177, thereby cutting the two consecutive elongated filled food items 279, turning the filled food items 279 into a plurality of small segments (short in length). It is worth mentioning that the blade 171... When two consecutive elongated filled food items 279 are cut, the two consecutive elongated filled food items 279 are supported by the support frame 177, so that the cutter 171 can smoothly cut the two consecutive elongated filled food items 279. In addition, when the cutter 171 is in the lowest position, it is pressed into the elastic buffer 197, which not only ensures that the two consecutive elongated filled food items 279 are cut, but also reduces the noise of the cutter 171 (the noise generated by the cutter 171 colliding with other objects).

[0072] The stuffed food 279, cut into multiple segments, deforms at both ends (becomes flattened to a certain extent) due to the pressure from the blade 171. The cut multiple segments of stuffed food 279 move onto the second conveyor belt 255 of the second conveyor belt device 200. These cut multiple segments of stuffed food 279 continue to be moved by the second conveyor belt 255 between the two shaping rollers 271 of each of the two shaping devices 257. After passing through the two shaping devices 257, the two ends of each cut multiple segment of stuffed food 279 can be restored to a state that is not flattened (e.g., the transverse cross-sectional shape is circular).

[0073] As can be understood from the foregoing technical features of the present invention, the stuffed food forming machine 10 of the present invention includes at least the following advantages. For example, the movable part 36 of the first conveyor belt device 30 can pivot to the cleaning position so that the first conveyor belt 70 is separated from the conveyor support 32, making cleaning and / or maintenance of the first conveyor belt device 30 quite convenient.

[0074] The movement of the first tension wheel 66 of the first conveyor belt device 30 can adjust the tension of the first conveyor belt 70. When the tension of the first conveyor belt 70 is large, the movable part 36 can remain in the conveying position. When the tension of the first conveyor belt 70 is small, the movable part 36 can easily pivot from the conveying position to the cleaning position, making cleaning and / or maintenance of the first conveyor belt device 30 quite convenient.

[0075] When the movable part 36 is in the clean position, the two fixing members 42 lock in, which can keep the movable part 36 in the clean position, making it very convenient to clean and / or maintain the first conveyor belt device 30.

[0076] The extrusion assembly 76 is rotatably engaged with the fitting sleeve 137 via the connector 111 and the limiting ring 131. When the extrusion assembly 76 is subjected to a reaction force along the axial direction parallel to the extrusion assembly 76, the limiting ring 131 will not move, making it difficult for the extrusion assembly 76 to separate from the fitting sleeve 137 during operation, thus ensuring that the filling device 72 can operate normally.

[0077] The cutting device 157 provides an elastic buffer 197 below the blade 171, so that the support frame 177 can support the filled food 279 when the blade 171 cuts the filled food 279, so that the soft filled food 279 can be cut reliably and the buffer 197 can reduce the noise of the blade 171 operating.

[0078] Two symmetrical support frames 173 are fixed on the second side 26 of the first bracket 20. The two support frames 173 are screwed to two adjusting screws 175. The two adjusting screws 175 abut against the bottom surface 193 of the support frame 177. Rotating the two adjusting screws 175 can finely adjust and position the support frame 177 so that the support frame 177 can be located at an appropriate height, making the process of cutting the stuffed food 279 smoother.

[0079] The two movable units 231 of the second conveyor belt device 200 can be pivoted to the maintenance position, so that the second conveyor belt 255 is separated from the fixed unit 211 and the upper surface of the two movable units 231, making the maintenance and cleaning of the second conveyor belt device 200 easier.

[0080] The basic teachings of the present invention have been explained, and many extensions and variations will be apparent to those skilled in the art. For example, the stuffed food forming machine 10 may exclude the second conveyor belt device 200, the second support 199, and the two shaping devices 257, so that the plurality of stuffed foods 279 cut off are only flattened at both ends, but the plurality of stuffed foods 279 cut off are still edible.

[0081] Since the invention disclosed in the specification can be practiced in other specific forms without departing from the spirit or general characteristics of the invention, and some of these specific forms have been pointed out, the embodiments disclosed in the specification should be regarded as illustrative rather than limiting. The scope of the invention is defined by the appended claims, not by the foregoing description, and all changes in meaning and scope falling within the claims shall still be included within its scope.
