[0010] In a preferred embodiment of an extrusion shaping device for wheat germ dough biscuit production, the shifting spindle arm slides up and down within a shifting limiting sleeve and rotates within the shifting limiting sleeve. The guide rail convex slide head slides within a corrugated guide rail groove. A shifting guide rail drive structure is formed between the guide rail convex slide head and the corrugated guide rail groove on the dough extrusion head shifting frame assembly of the wheat germ dough extrusion head assembly.

[0011] In a preferred embodiment of an extrusion shaping device for producing wheat germ biscuits, when the guide rail convex slide head is in the top positioning transition groove, the wheat germ dough extrusion end and the dough extrusion head form a directly facing splicing structure; when the guide rail convex slide head is in the bottom positioning transition groove, the wheat germ dough extrusion end and the dough extrusion head form a non-directly facing, to-be-replaced structure.

[0012] In a preferred embodiment of an extrusion shaping device for wheat germ biscuit production, the guide rail limiting protrusion on the edge of the bottom displacement frame slides vertically and vertically within the U-shaped groove vertical sliding arm on the bottom surface of the displacement limiting seat. Through the linear sliding limiting cooperation between the guide rail limiting protrusion and the U-shaped groove vertical sliding arm, the bottom displacement frame forms a vertically supporting base structure on the dough extrusion head displacement frame assembly.

[0013] In a preferred embodiment of an extrusion shaping device for producing wheat germ dough biscuits, the bottom of the extrusion head return spring abuts against the inner push arm platform, and the top of the extrusion head return spring abuts against the top groove of the bottom annular groove.

[0016] Compared with the prior art, the beneficial effects of the invention are as follows: The wheat germ dough extrusion head assembly is equipped with multiple wheat germ dough extrusion ends of different models. The wheat germ dough extrusion head assembly is mounted on a dough extrusion head changing frame assembly. The wheat germ dough extrusion head assembly forms a vertically displaced and rotating dough extrusion head changing structure on the dough extrusion head changing frame assembly. A cam drive structure is formed at the top of the dough extrusion head changing frame assembly to automatically change the position of the wheat germ dough extrusion head assembly. That is, each time the wheat germ dough extrusion head assembly is pressed once by the cam of the dough extrusion head changing frame assembly, the wheat germ dough on the wheat germ dough extrusion head assembly... The extrusion head moves downward and disengages from the dough extrusion head. At this time, the wheat germ dough extrusion head assembly rotates on the dough extrusion head changing frame assembly, realizing the rotational changing between two adjacent wheat germ dough extrusion heads. Then, after the cam pressing is completed, the wheat germ dough extrusion head assembly rotates and moves upward on the dough extrusion head changing frame assembly. At this time, the changed wheat germ dough extrusion head re-engages with the dough extrusion head, thus realizing the pressing-type rapid changing operation between different wheat germ dough extrusion heads. Its changing working principle is as follows: through the push of the extrusion head return spring, the pressing shaft end plate at the top of the changing spindle arm always abuts against the extrusion head. On the drive cam, when the drive cam rotates, the shifting spindle arm slides up and down within the shifting limit sleeve, and the shifting spindle arm rotates within the shifting limit sleeve. The guide rail convex slide head slides within the corrugated guide rail groove. Between the guide rail convex slide head and the corrugated guide rail groove, a shifting guide rail drive structure is formed on the dough extrusion head shifting frame assembly of the wheat germ dough extrusion head assembly. When the guide rail convex slide head is in the top positioning transition groove, a directly facing spliced ​​structure is formed between the wheat germ dough extrusion end and the dough extrusion head. When the guide rail convex slide head is in the bottom positioning transition groove, a non-directly facing shifting structure is formed between the wheat germ dough extrusion end and the dough extrusion head. Simultaneously, the bottom... A limiting ratchet is rotatably installed on the bottom end face of the displacement frame. A pushing spring is installed between the limiting ratchet and the pushing support plate. A limiting ratchet is fixedly installed at the bottom of the bottom rotating shaft. The bottom rod of the bottom rotating shaft is rotatably mounted on the bottom displacement frame through a bearing seat. By pushing the pushing spring, the front end of the limiting ratchet abuts against the limiting ratchet. Through the cooperation of the limiting ratchet and the limiting ratchet, the bottom rotating shaft can achieve unidirectional rotation on the wheat germ dough extruder assembly. The unidirectional rotation structure ensures that the wheat germ dough extruder assembly rotates in the same direction on the dough extruder head changing frame assembly every time it is pressed, avoiding rotational confusion during changing.

A push inner arm platform 110 is fixedly installed between the U-shaped groove vertical sliding arms 108, and an inner arm platform sliding hole 111 is opened on the push inner arm platform 110.

[0027] In a preferred embodiment, please refer to Figure 5 and Figure 6The wheat germ extrusion head assembly 200 includes a shifting spindle arm 201. A corrugated guide rail groove 205 is formed on the surrounding wall of the shifting spindle arm 201. A top positioning transition groove 204 is provided at the top of the corrugated guide rail groove 205, and a bottom positioning transition groove 206 is provided at the bottom of the corrugated guide rail groove 205. A bottom annular groove 215 and a bottom rotating shaft 210 are provided at the bottom of the shifting spindle arm 201. A bottom displacement platform 208 is fixedly provided at the bottom of the bottom rotating shaft 210. Guide rail limiting protrusions 207 are fixedly provided on the edge of the bottom displacement platform 208. A limiting ratchet 209 is fixedly provided at the bottom of the bottom rotating shaft 210. A pusher plate 216 is fixedly installed on the bottom end face of the bottom displacement frame 208, and a limiting ratchet 211 is rotatably installed on the bottom end face of the bottom displacement frame 208. A pusher spring 217 is installed between the limiting ratchet 211 and the pusher plate 216. An extrusion head reset spring 212 is installed inside the bottom annular groove 215. A main shaft arm top seat 202 is fixedly installed on the top of the shifting main shaft arm 201. A pressing shaft end seat 203 is rotatably installed on the main shaft arm top seat 202 through a shaft and a bearing seat. Multiple wheat germ extrusion ends 213 of different models are fixedly installed on the outer periphery of the shifting main shaft arm 201 through a Z-shaped support arm 214.

[0028] In this embodiment, the shifting spindle arm 201 slides up and down within the shifting limiting seat 106, and rotates within the shifting limiting seat 106, while the guide rail convex slide head 107 slides within the corrugated guide rail groove 205.

[0029] Secondly, please refer to it again. Figure 4 and Figure 5 The guide rail convex slide head 107 and the corrugated guide rail groove 205 form a shifting guide rail drive structure for the wheat germ dough extrusion head assembly 200 on the dough extrusion head shifting frame assembly 100. When the guide rail convex slide head 107 is at the top positioning transition groove 204, the wheat germ dough extrusion end 213 and the dough extrusion head 300 form a head-to-head splicing structure. When the guide rail convex slide head 107 is at the bottom positioning transition groove 206, the wheat germ dough extrusion end 213 and the dough extrusion head 300 form a non-head-to-head shifting structure.

[0030] Through the coordination of the above structures, the wheat germ dough extrusion head assembly 200 can move up and down on the dough extrusion head changing frame assembly 100. At the same time, while the wheat germ dough extrusion head assembly 200 moves up and down, the wheat germ dough extrusion head assembly 200 can rotate and change position on the dough extrusion head changing frame assembly 100.

[0031] Secondly, please refer to the following as well. Figure 4 and Figure 5 , Figure 6The guide rail limiting protrusion 207 on the edge of the bottom displacement frame 208 slides vertically and vertically within the U-shaped groove vertical sliding arm 108 on the bottom surface of the shifting limiting seat 106. Through the linear sliding limiting cooperation between the guide rail limiting protrusion 207 and the U-shaped groove vertical sliding arm 108, the bottom displacement frame 208 forms a straight-up and straight-down support frame structure on the preform extrusion head shifting frame assembly 100.

[0032] A limiting ratchet 211 is rotatably provided on the bottom end surface of the bottom displacement platform 208. A pushing spring 217 is provided between the limiting ratchet 211 and the pushing support plate 216. A limiting ratchet 209 is fixedly provided at the bottom of the bottom rotating shaft 210. The bottom rod of the bottom rotating shaft 210 is rotatably mounted on the bottom displacement platform 208 through a bearing seat.

[0033] In this embodiment, the front end of the limiting ratchet 211 engages with the limiting ratchet 209 through the pushing of the pushing spring 217. Through the cooperation of the limiting ratchet 211 and the limiting ratchet 209, the bottom rotating shaft 210 can rotate unidirectionally on the wheat germ extrusion head assembly 200.

[0034] In a preferred embodiment, please refer to Figure 4 and Figure 6 The bottom of the extrusion head return spring 212 abuts against the inner push arm platform 110, and the top of the extrusion head return spring 212 abuts against the top groove of the bottom annular groove 215. Through the push of the extrusion head return spring 212, the wheat germ dough extrusion head assembly 200 is in an upward push-abutting structure on the dough extrusion head changing frame assembly 100.

[0035] In this embodiment, the pressing shaft end plate 203 at the top of the shifting spindle arm 201 is always in contact with the drive cam 104 due to the pushing of the extrusion head return spring 212. Through the rotation of the drive cam 104, the wheat germ dough extrusion head assembly 200 forms a pressing structure that moves up and down on the dough extrusion head shifting frame assembly 100. When the protruding wheel of the drive cam 104 is in contact with the pressing shaft end plate 203 in the forward direction, the guide rail convex slide head 107 on the inner wall of the shifting limit seat 106 is located at the bottom positioning transition groove 206. When the protruding wheel of the drive cam 104 is in contact with the pressing shaft end plate 203 in the reverse direction, the guide rail convex slide head 107 on the inner wall of the shifting limit seat 106 is located at the top positioning transition groove 204.

[0036] In another embodiment of the present invention, both the bottom positioning transition groove 206 and the top positioning transition groove 204 have a certain depth. This ensures that the wheat germ dough extrusion head assembly 200 has a straight upward or straight downward trajectory when the dough extrusion head changing frame assembly 100 moves up and down. This ensures that the wheat germ dough extrusion end 213 and the bottom of the dough cake extrusion head 300 can better abut and engage.

[0037] The working principle of this invention is as follows: A wheat germ dough extrusion head assembly 200 is provided with multiple wheat germ dough extrusion ends 213 of different models. The wheat germ dough extrusion head assembly 200 is mounted on a dough extrusion head changing frame assembly 100. The wheat germ dough extrusion head assembly 200 forms a vertically displaced and rotating dough extrusion head changing structure on the dough extrusion head changing frame assembly 100. A cam drive structure is formed at the top of the dough extrusion head changing frame assembly 100 to drive the wheat germ dough extrusion head assembly 200 to automatically change position. That is, each time the wheat germ dough extrusion head assembly 200 is pressed once by the cam of the dough extrusion head changing frame assembly 100, the wheat germ dough extrusion ends 213 on the wheat germ dough extrusion head assembly 200... 13 moves downward and disengages from the dough extrusion head 300. At this time, the wheat germ dough extrusion head assembly 200 rotates on the dough extrusion head changing frame assembly 100, realizing the rotational changing between two adjacent wheat germ dough extrusion ends 213. Then, after the cam pressing is completed, the wheat germ dough extrusion head assembly 200 rotates and moves upward on the dough extrusion head changing frame assembly 100. At this time, the changed wheat germ dough extrusion end 213 re-connects and abuts with the dough extrusion head 300, thereby realizing the pressing-type rapid changing operation between different wheat germ dough extrusion ends 213. Its changing working principle is as follows: through the push of the extrusion head return spring 212, the pressing shaft end platform 203 at the top of the changing main shaft arm 201 is always The drive cam 104 is engaged with the shifting spindle arm 201. When the drive cam 104 rotates, the shifting spindle arm 201 slides up and down within the shifting limit sleeve 106, and the shifting spindle arm 201 rotates within the shifting limit sleeve 106. The guide rail convex slide head 107 slides within the corrugated guide rail groove 205. The guide rail convex slide head 107 and the corrugated guide rail groove 205 form a shifting guide rail drive structure for the wheat germ dough extrusion head assembly 200 on the dough extrusion head shifting frame assembly 100. When the guide rail convex slide head 107 is at the top positioning transition groove 204, the wheat germ dough extrusion end 213 and the dough cake extrusion head 300 form a facing splicing structure. When the guide rail convex slide head 107 is at the bottom positioning transition groove 206, the wheat germ dough extrusion end... The head 213 and the dough extrusion head 300 form a misaligned, interchangeable structure. Simultaneously, a limiting ratchet 211 is rotatably mounted on the bottom end face of the bottom displacement platform 208. A pushing spring 217 is positioned between the limiting ratchet 211 and the push plate 216. A limiting ratchet 209 is fixedly mounted at the bottom of the bottom rotating shaft 210. The bottom shaft 210 is rotatably mounted on the bottom displacement platform 208 via a bearing seat. Through the pushing of the push spring 217, the front end of the limiting ratchet 211 engages with the limiting ratchet 209. The engagement of the limiting ratchet 211 and the limiting ratchet 209 enables unidirectional rotation of the bottom rotating shaft 210 on the wheat germ dough extrusion head assembly 200. This unidirectional rotation structure ensures that each pressing...Both methods ensure that the wheat germ dough extruder assembly 200 rotates in the same direction on the dough extruder changing frame assembly 100, preventing rotational misalignment during changing.
