DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0017] like Figure 1-Figure 5 As shown, an extrusion molding device for food production provided by one embodiment of the present invention includes a workbench 1 and also includes: A pre-processing module 2, which is installed on the workbench 1 and is used to pre-extrude the food raw materials to be processed and make the extruded food raw materials into strips with a certain thickness; A molding processing module 3, wherein the molding processing module 3 comprises a second driving motor 31 installed on the workbench 1, wherein the output end of the second driving motor 31 is connected to a driving shaft 32, wherein two connecting frames 33 are symmetrically arranged on the driving shaft 32, wherein a plurality of molding dies 34 are arranged in a ring between the two connecting frames 33, wherein each of the molding dies 34 is provided with a plurality of molding cavities 341 equidistantly distributed along the axial direction of the driving shaft 32, and an adjustable pressing plate 35 is slidably installed in each of the molding cavities 341 along the radial direction of the driving shaft 32; A control module 4, wherein the control module 4 includes a plurality of adjustment slides 41 mounted in a ring on the drive shaft 32, and the number of the adjustment slides 41 is the same as the number of the forming molds 34, the adjustment slides 41 are slidably mounted on the drive shaft 32 along the axial direction of the drive shaft 32, the end of the adjustment slide 41 close to the second drive motor 31 is connected to the drive shaft 32 through a plurality of return springs 43, a plurality of adjustment connecting rods 42 are equidistantly mounted on the adjustment slide 41, and the number of the adjustment connecting rods 42 on one of the adjustment slides 41 is the same as the number of forming cavities 341 in a forming mold 34, one end of the adjustment connecting rod 42 is hinged on the adjustment slide 41, and the other end of the adjustment connecting rod 42 is hinged on the adjustable pressure plate 35, and the control module 4 also includes an adjustment unit arranged at the end of the drive shaft 32 away from the second drive motor 31, and the adjustment unit is used to push the adjustment slide 41 located at the bottom to perform a reciprocating motion along the axial direction of the drive shaft 32.

[0018] In the embodiment of the present invention, when in use, the food raw material to be processed is first extruded into a strip of a specified thickness through the pre-processing module 2, and the pre-extruded food raw material is transported to the molding processing module 3 for extrusion molding. When the food extrusion molding is to be performed, it is only necessary to start the second drive motor 31, the second drive motor 31 can drive the drive shaft 32 to rotate, and the drive shaft 32 can drive each molding mold 34 to rotate synchronously through the connecting frame 33. As each molding mold 34 rotates, the molding mold 34 located directly below will extrude the food raw material, so that the food raw material is pressed into the cross-sectional shape of the molding cavity 341. At the same time, the adjusting unit will push the adjusting slide plate 41 at the bottom to slide axially along the driving shaft 32. The adjusting slide plate 41 can drive the adjustable pressure plates 35 located directly below to slide synchronously in the corresponding forming cavity 341 through the return spring 43 arranged thereon, thereby squeezing the food raw materials in the forming cavity 341. The single displacement of the adjusting slide plate 41 can also be adjusted by the adjusting unit, and then the compression amount of the adjustable pressure plate 35 can be adjusted, so that the food raw materials in the forming cavity 341 can be squeezed to different degrees, so that the processed food has different firmness.

[0019] like Figure 1 and Figure 6 As shown, as a preferred embodiment of the present invention, the pre-processing module 2 includes a mounting frame 21 installed on the workbench 1, and a mounting plate 22 is slidably installed on the mounting frame 21 along the vertical direction, and a first telescopic member 23 for driving the mounting plate 22 to slide up and down is also provided on the top of the mounting frame 21, and a pressure roller 24 is rotatably installed on the bottom of the mounting plate 22, and a first driving motor 25 is also installed on the mounting plate 22, and the output end of the first driving motor 25 is connected to the pressure roller 24 through a transmission member.

[0020] In the embodiment of the present invention, the first telescopic member 23 may be an electric telescopic rod or a telescopic cylinder, etc., and the transmission member is a pulley belt mechanism. When in use, the first telescopic member 23 only needs to be controlled to be telescopic, so as to drive the mounting plate 22 to move up and down along the slide groove provided on the mounting frame 21, thereby driving the pressing roller 24 to move up and down synchronously through the mounting plate 22, and adjusting the distance between the bottom end of the mounting plate 22 and the upper surface of the workbench 1. Then the first drive motor 25 can be started, and the first drive motor 25 drives the pressing roller 24 to rotate synchronously through the pulley belt mechanism, so as to extrude the food raw material to be processed into a strip of a specified thickness, and transport the pre-extruded food raw material to the molding processing module 3 for extrusion molding.

[0021] like Figure 6As shown, as a preferred embodiment of the present invention, the pre-processing module 2 also includes a scraper 26 installed on the mounting plate 22, and the mounting plate 22 is arranged on the material incoming side of the pressure roller 24 (i.e., the side where the raw materials are put in) and abuts against the side wall of the pressure roller 24.

[0022] In an embodiment of the present invention, the scraper 26 can be used to scrape off the food raw materials attached to the pressing roller 24. The scraped raw materials will fall to the bottom and will be squeezed by the pressing roller 24 together with other food raw materials and then transported to the forming processing module 3, thereby effectively preventing excessive food raw materials from remaining on the pressing roller 24 and affecting the subsequent processing quality.

[0023] like Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, the adjusting unit includes a limiting triangle block 44 installed on the inner wall of the adjusting slide plate 41, and a second telescopic member 46 arranged on the workbench 1, the second telescopic member 46 can be linearly telescopic along the axial direction of the driving shaft 32, and the telescopic end of the second telescopic member 46 is connected to the adjusting lever 45.

[0024] In the embodiment of the present invention, the second telescopic member 46 is an electric telescopic rod. When in use, as the drive shaft 32 rotates, each adjustment slide plate 41 will rotate synchronously. When an adjustment slide plate 41 rotates to the bottom, the limiting triangle block 44 provided at its end will abut against the adjustment stop rod 45. Through the limiting effect of the adjustment stop rod 45 on the inclined surface of the limiting triangle block 44, as the drive shaft 32 rotates, the adjustment slide plate 41 will slide along the axial direction of the drive shaft 32. The adjustment slide plate 41 can drive each adjustable pressure plate 35 located directly below to slide synchronously in the molding cavity 341 through the reset spring 43 provided thereon, thereby squeezing the food raw materials in the molding cavity 341. By controlling the second telescopic member 46 to extend and retract, the contact position of the adjusting stop rod 45 and the limiting triangle block 44 can be controlled, thereby adjusting the single displacement of the adjustment slide plate 41, and then adjusting the compression of the adjustable pressure plate 35, so that the food raw materials in the molding cavity 341 can be squeezed to different degrees, so that the processed food has different compactness.

[0025] When the limiting triangle block 44 rotates to disengage from the adjusting stop rod 45, the elastic restoring force of the reset spring 43 will restore the adjusting slide plate 41 to the initial position, thereby causing the adjustable pressure plate 35 to simultaneously restore the initial position and wait for the next processing.

[0026] Working principle: When in use, first control the first telescopic member 23 to extend and retract, so as to drive the mounting plate 22 to move up and down along the slide groove provided on the mounting frame 21, thereby driving the pressing roller 24 to move up and down synchronously through the mounting plate 22, and adjusting the distance between the bottom end of the mounting plate 22 and the upper surface of the workbench 1. Then the first drive motor 25 can be started, and the first drive motor 25 drives the pressing roller 24 to rotate synchronously through the pulley belt mechanism, so as to extrude the food raw material to be processed into a strip of a specified thickness, and transport the pre-extruded food raw material to the molding processing module 3 for extrusion molding. Then start the second drive motor 31, and the second drive motor 31 can drive the drive shaft 32 to rotate, and the drive shaft 32 can drive each molding mold 34 to rotate synchronously through the connecting frame 33. As each molding mold 34 rotates, the molding mold 34 located directly below will extrude the food raw material, so that the food raw material is pressed into the cross-sectional shape of the molding cavity 341. At the same time, with the rotation of the drive shaft 32, each adjusting slide plate 41 will rotate synchronously. When an adjusting slide plate 41 rotates to the lowest position, the limiting triangle block 44 arranged at its end will abut against the adjusting stop rod 45. Through the limiting effect of the adjusting stop rod 45 on the inclined surface of the limiting triangle block 44, with the rotation of the drive shaft 32, the adjusting slide plate 41 will slide along the axial direction of the drive shaft 32. The adjusting slide plate 41 can drive the adjustable pressure plates 35 located directly below to slide synchronously in the molding cavity 341 through the return spring 43 arranged thereon, thereby squeezing the food raw materials in the molding cavity 341. By controlling the second telescopic member 46 to extend and retract, the contact position of the adjusting stop rod 45 and the limiting triangle block 44 can be controlled, thereby adjusting the single displacement of the adjusting slide plate 41, and then adjusting the compression amount of the adjustable pressure plate 35, so that the food raw materials in the molding cavity 341 can be squeezed to different degrees, so that the processed food obtains different firmness.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
