[0004] 1. The structural design that uses a swing ring to drive the rotation and opening / closing of the flower-knitting knife and the knife edges of the flower-knitting knife are in point contact not only has a relatively large volume, but also is prone to generating knife-edge gaps. It is easy for dough to get stuck when the knife edges open and close, resulting in waste dough being generated inside the knife body and falling onto the biscuit embryo, affecting the forming quality of the product.

[0005] 2. The structural design of using a gear asynchronous drive cannot drive all the flower-knitting knives to move synchronously at the same time, the control is not precise enough, the production process is not smooth enough, and the flower-knitting efficiency is low.

[0006] Therefore, there is an urgent need to design a flower-knitting forming knife with a tight connection, not prone to generating dough scraps, and the synchronous opening and closing of multiple flower-knitting knife components, so as to improve the flower-knitting efficiency and the forming quality of the product, reduce the generation of waste, ensure a clean production process, and have a long service life.

The opening and closing of multiple sets of pinching knife assemblies are driven by multiple sets of connecting rods fixed on the linear shafts. Compared with the structure of a single connecting rod, the synchronous opening and closing of each set of pinching knife assemblies can be accurately controlled, and the force is evenly distributed during the opening and closing process, making the work smoother, greatly improving the pinching efficiency and reliability.

[0053] Next, in combination with the drawings and the specific implementation manner, the present invention will be further described:

[0054] As Figure 1-7 shown, a flower-knurling forming knife includes a bottom plate 1, a flower-knurling knife mechanism 4, a transmission mechanism 2 and a driving mechanism 3;

[0055] The bottom plate 1 is connected to an external bracket, and at least two groups of mutually parallel feed channels 110 are opened on the bottom plate 1, and the two side edges of the bottom plate 1 are arranged parallel to each other;

[0056] The feeding channel 110 includes at least two feeding ports 1a linearly distributed along the length direction of the bottom plate 1, and the feeding ports 1a of adjacent feeding channels 110 are arranged in a staggered manner;

[0057] As Figure 7 shown, the feeding port 1a is a regular hexagon, the side of the feeding port 1a close to the side of the bottom plate 1 is parallel to the side of the bottom plate 1, and a knurling knife mechanism 4 is arranged on each of the feeding ports 1a;

[0058] The knurling knife mechanism 4 includes a knife limiting component 5 and a knurling knife component 6;

[0059] The knurling knife component 6 includes six knurling knife bodies 61 circumferentially distributed around the axis of the feeding port 1a, and two connecting rods 62 arranged opposite to each other front and back. The knurling knife bodies 61 are arranged in one-to-one correspondence with the sides of the feeding port 1a;

[0060] As Figure 7 shown, one end of any of the knurling knife bodies 61 is in non-separable linear sliding connection with the corresponding side of the feeding port 1a, and the other end is provided with a sliding groove 61a that slidably fits with the cutting edge 61c of the adjacent knurling knife body 61. The angle between the knurling knife body 61 and the side with which it is slidably connected is 60 degrees. When any of the knurling knife bodies 61 slides linearly, its angular relationship with any other knurling knife body 61 remains unchanged;

[0061] As Figure 4 、 6 、7 shown, a through shaft hole 61b is provided at one end of the knurling knife body 61 away from the sliding groove 61a, and a rotatable pin shaft 7 is arranged on the shaft hole 61b. When the knurling knife body 61 slides, a knurling channel 100 that can be opened and closed is formed in the middle of the knurling knife component 6. The knurling channel 100 is in the shape of a regular hexagon in the open state;

[0062] As Figure 4 shown, the knife limiting component 5 is in close contact with the upper and lower surfaces of the knurling knife body 61, and the knife limiting component 5 is used to limit the freedom degree of the knurling knife body 61 moving up and down relative to the feeding port 1a when sliding;

[0063] The transmission mechanism 2 is arranged opposite to each other front and back on the outer side of the side of the bottom plate 1;

[0064] As Figure 1 、 2 、6、7 shown, the connecting rod 62 is located above the knurling knife component 6. One end of the connecting rod 62 is fixedly connected to the transmission mechanism 2, and the other end is connected to the end of the pin shaft 7 close to the side of the bottom plate 1.

Compared with the existing flower-knurling tool structure with a point contact at the cutting edge and a rotary opening and closing, it has a smaller volume and better cutting edge sealing performance. During the flower-knurling process, the dough is not easily introduced into the flower-knurling tool mechanism 4 between the tool limiting component 5 and the flower-knurling tool assembly 6 and between the flower-knurling tool bodies 61; thus, it is not easy to generate waste dough and dough scraps, improving the quality of the product's flower-knurling forming, reducing the generation of waste, and ensuring a clean production process.

[0068] In addition, in this embodiment, two link rods 62 arranged opposite to each other in the front and back and performing reciprocating linear motion are used to drive all the flower-knurling tool assemblies 6 to open and close synchronously. Compared with the structure of a single link rod 62, each group of flower-knurling tool assemblies 6 is symmetrically powered by two link rods 62, enabling each group of flower-knurling tool assemblies 6 to be evenly stressed during the opening and closing process, so that the work is smoother, greatly improving the flower-knurling efficiency and reliability.

[0069] In addition, in this embodiment, in order to save costs and reduce weight, a material-saving groove 62a is provided on the long-sized link rod 62.

[0070] Furthermore, as shown in Figure 1 、 2 、4, 6, and 7, in order to prevent the flower-knurling tool body 61 from detaching from the feed inlet 1a, and to improve the smoothness and tightness of the linear sliding of the flower-knurling tool body 61 at the feed inlet 1a; the tool limiting component 5 includes limiting plates 51 oppositely arranged above and below the feed inlet 1a;

[0071] The limiting plate 51 is detachably and fixedly connected to the bottom plate 1. A through hole 51a is provided in the middle of the limiting plate 51. Six linearly penetrating grooves 51b distributed in a circular pattern are provided in the area of the limiting plate 51 between the through hole 51a and the feed inlet 1a. The limiting plate 51 is in close fit with the flower-knurling tool body 61;

[0072] The linearly penetrating grooves 51b are arranged in one-to-one correspondence with the sides of the feed inlet 1a, and the linearly penetrating grooves 51b are arranged parallel to the sides of the feed inlet 1a corresponding to them; both ends of the pin shaft 7 pass through the linearly penetrating grooves 51b of the upper and lower limiting plates 51 respectively and are slidably connected to the linearly penetrating grooves 51b.

[0073] Furthermore, as shown in Figure 1 、2 As shown, the transmission mechanism 2 includes connecting plates 21 fixedly arranged at both ends of the bottom plate 1, and linear shafts 22 oppositely arranged on both sides of the bottom plate 1;

[0074] Sliding holes 21a are oppositely formed at both ends of the connecting plate 21. Both ends of the linear shaft 22 are slidably connected to the sliding holes 21a. One end of the connecting rod 62 far from the pin shaft 7 is fixedly connected to the middle of the linear shaft 22;

[0075] The driving mechanism 3 is located on the side of the connecting plate 21 away from the flower-knife mechanism. The driving ends of the driving mechanism 3 are respectively in transmission connection with the ends of the two linear shafts 22.

[0076] In this embodiment, the two connecting rods 62 of each flower-knife assembly 6 are respectively powered by symmetrically arranged linear shafts 22, so as to ensure that the two connecting rods 62 moving linearly and reciprocally in opposite directions are evenly stressed.

[0077] In this embodiment, in order to improve the smooth movement of the linear shaft 22, a bearing 8 is arranged between the linear shaft 22 and the sliding hole 21a.

[0078] Furthermore, as Figure 1 、 3 shown, the driving mechanism 3 includes a motor 31, an eccentric roller 32, a swing arm 33, a linkage rod 34, a rotary positioning plate 35 and a rotary shaft 36;

[0079] The motor 31 is located on the side of the connecting plate 21 away from the flower-knife mechanism, and the motor 31 is connected to the bottom plate 1;

[0080] The rotary shaft 36 is located between the motor 31 and the connecting plate 21. The axis of the rotary shaft 36 coincides with the symmetry line of the two linear shafts 22. The middle of the rotary shaft 36 is rotatably connected to the bottom plate 1. One end of the rotary shaft 36 is connected to the middle of the swing arm 33, and the other end is connected to the rotary positioning plate 35;

[0081] Two linkage rods 34 are provided and are oppositely arranged on both sides of the bottom plate 1. Both ends of the linkage rod 34 are respectively rotatably connected to the end of the swing arm 33 and the end of the linear shaft 22 through a rotating shaft;

[0082] A waist-shaped hole 35a is formed at one end of the rotary positioning plate 35 far from the rotary shaft 36;

[0083] One end of the eccentric roller 32 passes through the bottom plate 1 and is connected to the driving end of the motor 31, and the other end is provided with an eccentric shaft 9. The other end of the eccentric shaft 9 is movably arranged in the waist-shaped hole 35a of the rotary positioning plate 35.

[0084] In this embodiment, the eccentric roller 32 is driven to rotate by the motor 31 through deceleration. The rotation of the eccentric roller 32 drives the rotary positioning plate 35 to swing left and right reciprocally through the eccentric shaft 9, so as to synchronously drive the two ends of the swing arm 33 to swing left and right reciprocally through the rotation of the rotary shaft 36, thereby synchronously driving the linear shafts 22 on the left and right sides to move linearly reciprocally. Then, a plurality of connecting rods 62 fixed on the linear shafts 22 drive a plurality of flower - kneading knife assemblies 6 to open and close, so as to achieve the purpose of pinching off and closing the dough opening.

[0085] The above - mentioned eccentric - wheel - driven two - connecting - rod 62 synchronous - drive structure can accurately control the synchronous opening and closing of all the flower - kneading knife assemblies 6, ensuring the flower - kneading effect.

[0086] Furthermore, as Figure 6 shown, in order to improve the stable and firm connection between the limit plate 51 and the base; a plurality of connection holes 51c are opened around the outside of the linear through - groove 51b on the limit plate 51, locking screws are arranged on the connection holes 51c, and lock holes 1b corresponding to the connection holes 51c one by one are opened on the bottom plate 1; the limit plate 51 is fixedly connected to the bottom plate 1 by means of screwing.

[0088] Furthermore, as Figure 4 、 6 shown, in order to adjust the fitting clearance and buffer vibration and noise; an installation hole 62b is arranged at one end of the connecting rod 62 away from the linear shaft 22, the end of the pin shaft 7 is non - rotatably connected to the connecting rod 62 through the installation hole 62b, and a copper sleeve 10 is arranged between the end of the pin shaft 7 and the installation hole 62b; the copper sleeve 10 is pressed into the space between the end of the pin shaft 7 and the installation hole 62b as a replaceable bush to correct the machining error of the parts, eliminate the play between the shaft and the hole, realize the accurate control of the synchronous opening and closing of each flower - kneading knife assembly 6, and at the same time absorb mechanical vibration through the softness of copper and reduce the running noise.

[0089] Furthermore, as Figure 3 shown, in order to ensure that the motor 31 operates in the high - efficiency range, extend the service life of the equipment and adapt to the complex mechanical environment; the drive shaft of the motor 31 is connected to the eccentric roller 32 through a reducer 11 and a coupling 12.

[0090] Furthermore, as Figure 3 shown, in order to improve the ability of the rotary shaft 36 to bear radial loads and ensure the coaxial stability of rotation; a deep - groove ball bearing 13 is arranged between the rotary shaft 36 and the rotational connection of the bottom plate 1.

[0091] Further, as Figure 4 shown, in order to completely scrape off the dough residue adhering to the blade 61c during the process of pinching the flowers and prevent the dough residue from remaining on the blade 61c; the blade 61c in contact with the chute 61a is completely covered by the chute 61a.

[0092] Working principle of the present invention:

[0093] When the present invention works, the motor 31 drives the eccentric roller 32 to rotate at a reduced speed. The rotation of the eccentric roller 32 drives the rotary positioning plate 35 to swing left and right reciprocally through the eccentric shaft 9. The swing of the rotary positioning plate 35 synchronously drives the two ends of the swing arm 33 to swing left and right reciprocally through the rotary shaft 36, thereby synchronously driving the linear shafts 22 on the left and right sides to perform linear reciprocating motion; a plurality of connecting rods 62 fixed on the linear shafts 22 drive a plurality of flower pinching knife assemblies 6 to open and close synchronously, that is, drive a plurality of flower pinching knife bodies 61 to slide linearly, so that their blades 61c gather to cut the dough or separate to open the flower pinching channel 100, thereby realizing cutting a plurality of doughs at the same time at one time;

[0094] The present invention is generally applied to cookie production equipment such as a cookie machine. The feeding roller of the cookie machine rotates for feeding, and the dough is extruded from a plurality of extrusion ports through the extrusion of the material pump. The flower pinching knife assemblies 6 are arranged in one-to-one correspondence with the extrusion ports. At this time, a plurality of flower pinching knife assemblies 6 of the present invention are all in an open state, and a plurality of doughs enter the flower pinching channel 100. When the predetermined length of the cookie blank is reached, it is cut off by a plurality of flower pinching knife assemblies 6 synchronously, thereby completing the production of a plurality of cookie blanks at one time.

[0095] In another embodiment, in order to further improve the production efficiency and ensure the flower pinching effect, the flower pinching forming knife of the present invention can follow the speed at which the dough is extruded from the extrusion port while pinching the dough, and the bottom plate 1 is connected to a lifting mechanism (not shown in the figure) that can reciprocate up and down through an external support.

[0096] For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
