Detailed Description

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in fig. 1 and 2, the head of the cookie dough forming machine disclosed by the invention comprises a machine body 8, wherein a hopper 1, a spiral extruding mechanism and a continuous forming mechanism are fixedly arranged on the machine body 8 from top to bottom in sequence. The screw type extrusion mechanism comprises an extrusion roller 2 which is horizontally installed, a helical blade 4 which is arranged along the axial direction of the extrusion roller 2 and a stepping motor 5 which is used for driving the helical blade 4. Helical blade 4 fixed mounting is on pivot 3, and the one end of pivot 3 is rotated with the left side of squeeze roll 2 and is connected, and behind the right-hand member baffle of squeeze roll 2, the other end of pivot 3 runs through, and is coaxial fixed with step motor 5's output shaft. The helical blade 4 is driven by a stepping motor 5 through a rotating shaft 3 to rotate inside the squeezing roller 2.

The feed inlet has been seted up to the upside that squeeze roll 2 is close to step motor 5, and the discharge opening 11 intercommunication feed inlet of 1 lower extreme of hopper to 1 lower extreme of hopper is sealed through the sealing washer with squeeze roll 2, avoids mixing the raw materials and leaks. A set of discharge gate has been seted up along the axial to the bottom of squeeze roll 2, and the equal threaded connection of each discharge gate has a mould ware 6, and the space between two adjacent flights of helical blade 4 is all aimed at to each discharge gate, also is the transfer passage of discharge gate intercommunication helical blade 4. In operation, a flow of mixed material is fed into the hopper 1 and flows into the squeeze roller 2 via the discharge opening 11 of the hopper 1 and the feed opening of the squeeze roller 2. Under the drive of the stepping motor 5, the helical blades 4 gradually fill the mixed material into the extrusion drum 2 and increase the pressure of the mixed material in the extrusion drum 2. After being conveyed and extruded by the helical blades 4, the mixed raw materials are extruded into and out of the material outlets and finally extruded into a die 6 connected with each material outlet for forming.

The above process is also a substantial process of extrusion molding of cookie dough. Wherein, the helical blade 4 not only plays the role of conveying mixed raw materials, but also plays the role of increasing extrusion force. In fig. 1, when the mixed raw material is conveyed from the inlet side to the outlet side, the mixed raw material is in a state of being flow-extruded at all times, and the mixed raw material is mixed and stirred once again, which is one of the functions of the helical blade 4. The cookie dough is extruded in the die 6 into a certain shape, and thus the die 6 substantially determines the shape of the cookie dough. Therefore, in the above structure, the mold device 6 is screwed with the discharge port, so that the mold device 6 can be conveniently replaced, and the shape of the cookie blank can be conveniently changed by replacing different mold devices 6.

The cookie dough, after being formed by the molder 6, needs to be cut to be finally formed. As shown in fig. 1 and 2, the continuous forming mechanism in this case includes a conveying assembly composed of a conveyor belt 91 and a conveyor wheel 92, and an elastic support assembly, wherein the conveyor belt 91 is sleeved on a transmission wheel 92, and the transmission assembly is similar to a belt transmission mechanism or a chain transmission mechanism. It should be noted that: the transmission combination includes a micro motor for driving the transmission wheel 92 to rotate and a mounting bracket 97, the transmission wheel 92 and the motor are both mounted on the mounting bracket 97, and the transmission wheel and the motor belong to the prior art, which are not further described in this specification for avoiding redundancy. In this embodiment, the outer surface of the upper half of the conveyor belt 91 is used to close the outlet at the lower end of the mold 6 and support the cookie blanks. Therefore, the conveying belt 91 in the scheme can be a transmission chain formed by hinging a plurality of stainless steel blocks or a wide belt made of food-grade silica gel leather, and meanwhile, the outer belt surface of the upper half part of the conveying belt 91 is always attached to the outlet at the lower end of the mould device 6 in the initial state, and the lower half part of the conveying belt 91 is suspended and does not contact cookie blanks.

The transmission assembly in this embodiment is fixed to the body 8 through the elastic support member. The method specifically comprises the following steps: the resilient support assembly includes a telescoping pole 94 and an electromagnetic module. The telescopic rod 94 is composed of a lower rod 941 and an upper rod, and the upper portion of the lower rod 941 is inserted into the inner cavity of the upper rod along the axial direction, i.e., the lower rod 941 can extend and retract along the axial direction of the upper rod. The upper end of the upper rod body is fixedly connected with the mounting frame 97, and the lower end of the lower rod body 941 is fixedly connected with the machine body 8. A pressure spring 95 is sleeved on the lower rod body 941, the upper end of the pressure spring 95 is abutted with the lower end of the upper rod body, and the lower end of the pressure spring 95 is abutted with the machine body 8 or an annular boss at the lower end of the lower rod body 941. The electromagnetic module comprises an electromagnet 93, an iron block 96 and a PLC controller, and the electromagnet 93 is electrically connected with the PLC. The electromagnet 93 is fixedly installed on the upper portion of the inner cavity of the upper rod body, and the iron block 96 is fixedly installed on the upper end of the lower rod body 941.

In the present case, the continuous forming mechanism further comprises a cutting assembly. As shown in fig. 2, the cutting assembly includes two sets of cutting assemblies disposed on both sides of the conveyor belt 91, the two sets of cutting assemblies being symmetrical in the conveying direction of the conveyor belt 91. Each set of cutting assembly comprises a single-edge cutter 101, a first rack 102, a second rack 104 and a transition gear 103, wherein the single-edge cutter 101 is in horizontal sliding fit with the machine body 8, the knife surface of the single-edge cutter 101 is flush with the outer belt surface of the upper half belt body of the conveyor belt 91 in the initial state, and the cutting edge of the single-edge cutter 101 faces the mold device 6. The first rack 102 is horizontally and fixedly installed on one side of the single-edge cutter 101 far away from the cutting edge, and the second rack 104 is vertically and fixedly installed on the installation frame 97. The transition gear 103 is a follower gear and is rotatably connected to the machine body 8, and the transition gear 103 is engaged with the first rack 102 and the second rack 104, respectively. As shown in fig. 1 and 2, when the transfer assembly moves down, the second rack 104 moves down in synchronization in the vertical direction while driving the transition gear 103 to rotate. The transition gear 103 rotates while the single-edge cutter 101 is driven by the first rack 102 to slide toward the die 6. The extruded cookie blanks are continuously extruded downwards from an outlet at the lower end of the die device 6, at the moment, two single-edge cutters 101 at two sides of the conveyor belt 91 quickly cut the extruded cookie blanks tangentially to complete cutting, and then the formed cookie blanks are obtained. At this time, the conveyor belt 91 is continuously conveyed, so that when the conveyor belt 91 rises, the two single-edge cutters 101 synchronously retreat, and the outer belt surface of the conveyor belt 91 is continuously attached to block the outlet at the lower end of the mold device 6. In the above structure, it is also possible to provide a set of cutting combinations on one side of the conveyor belt 91, but in the preferred embodiment, a set of cutting combinations is provided on each side of the conveyor belt 91. This is because: two sets of cutting combinations are arranged, and the advancing distance of the single-edge cutter 101 is short under the condition that the cutting stroke is fixed; under the condition that the rotation angle of the transition gear 103 is fixed, the time required for oppositely cutting and retracting the two single-edge cutters 101 is shorter, namely the descending distance of the conveying combination is shorter, so that high-frequency cutting can be realized, and the production efficiency of cookie blanks is improved. It should be noted that the cutting edge of the cutter in this case is very thin, and thus the illustration is only given as an example. A protective net 7 is fixedly arranged on the machine body 8, and the protective net 7 is used for protecting workers by extending a handle into a working area of the single-edge cutter 101 in a manner of misoperation.

In the present case, in the initial state, the supporting force of the elastic supporting component is equal to the gravity of the conveying assembly, and at this time, the outer belt surface of the upper half portion of the conveying belt 91 is always attached to the outlet at the lower end of the mold 6 in the initial state, and the two single-edge cutters 101 are retracted and located at the maximum distance. When the cookie dough is extruded from the die device 6, since the inner diameter of the die device 6 is fixed, the weight of the cookie dough is proportional to the thickness of the cookie dough, and the weight of the cookie dough is converted into the downward movement displacement of the conveying assembly, which is converted into the extending power and distance of the single-edged cutter 101 through the transition gear 103, the first rack 102 and the second rack 104. At this time, the height of the conveying assembly is lowered due to the increase in the weight of the cookie dough, and the two single-edged cutters 101 are moved toward each other from both sides of the conveyor belt 91. Before the device leaves a factory, size parameters can be set; when the cookie dough reaches the designed thickness dimension, the two single-edge cutters 101 come into contact and just cut off the cookie dough. Of course, two screws may be fixedly disposed side by side on the top surface of the first rack 102 along the length direction, and a strip-shaped hole, which is a countersunk hole, is disposed on the single-edge cutter 101 along the length direction. The cover is equipped with lock nut after the screw passes the bar hole on the single-edge cutter 101, and this lock nut sinks into the head in bar hole, just so can the extension length under the quick adjustment single-edge cutter 101 initial condition to conveniently adjust the cutting thickness of cookie biscuit as required. In the scheme, a first position sensor 50 is arranged on the machine body 8, and the first position sensor 50 is used for detecting whether two single-edge cutters 101 contact or not and synchronously feeding back and controlling the stepping motor 5 and the PLC controller according to detection data. When the two single-edge cutters 101 are contacted, the stepping motor 5 is stopped, so that the cookie blanks are not extruded in the mould device 6; meanwhile, the PLC controller controls the electromagnet 93 to start power supply work, the electromagnet 93 generates attraction force on the iron block 96, and further the telescopic rod 94 is enabled to contract, so that the conveying combination moves downwards by 0.5-1mm, and the top surface of the cut cookie blank is separated from the outlet at the lower end of the mould device 6 and the bottom surface of the single-edge cutter 101. After the conveying assembly moves down to the right position, the position collision block 51 on the mounting frame 97 contacts the second position sensor 52 on the machine body 8, the detection data of the second position sensor 52 controls the micro motor to work in a feedback mode, the micro motor drives the conveying belt 91 to work, and cut cookie blanks are conveyed away so as to be convenient for the next processing procedure. And, the operating time of the electromagnet 93 is set in advance according to the time for which the cookie blanks are conveyed. After the cookie biscuit is completely conveyed away, the electromagnet 93 is powered off, the conveying combination moves upwards to reset, the position collision block 51 is separated from the contact with the second position sensor 52 on the machine body 8, and the conveying belt 91 stops rotating; after the conveying assembly moves upwards to the maximum position, the two single-edge cutters 101 retract to the maximum distance, and the outer belt surface of the upper half belt body of the conveying belt 91 is attached to the outlet at the lower end of the mold device 6. At this time, after the third position sensor 53 on the machine body 8 receives the position signal of the upper half belt body of the conveyor belt 91, the stepping motor 5 is controlled to start up, and the cookie blank raw material is extruded into the die device 6 again.

It should be particularly noted that the cutting process of the cookie blanks and the process of moving up and resetting the conveying assembly in the case are very rapid, and continuous production can be realized. When the mold tool 6 needs to be replaced, the transition gear 103 is first removed, and then the continuous molding mechanism is removed.

The above description is only exemplary of the present invention and should not be taken as limiting, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
