The existing staggered cutting method of skewered food is: first, the stick-shaped food is placed on a simple cutting device and cut one by one, and the center of the cut food is manually put on a skewer. During the cutting process, it is generally necessary to manually put the stick-shaped food one by one, and operate the cutting knives on both sides of the cutting device.

DETAILED DESCRIPTION

[0050] The structure of the present invention is further described below with reference to the accompanying drawings and by way of examples. It should be noted that the present examples are descriptive rather than restrictive.

[0051] A fully automatic forming and processing equipment for string-shaped food, see Figure 1-Figure 10 The invention point is: it includes a frame, a sign feeding mechanism 5, a sign straightening mechanism 4, a loading mechanism 10, a bar clamping mechanism 3, a bar transfer mechanism 8, a pre-cutting and unfolding material receiving and feeding mechanism 11, a cutting and unfolding integrated mechanism 2, a sign feeding distance detection mechanism 6 and a bar length detection mechanism 7.

[0052] The frame is the basic component of the processing equipment, and its specific structural form is not limited. The upper end of the frame forms a mounting platform for realizing the centralized installation of the above-mentioned functional mechanisms. The frame is not shown in the accompanying drawings.

[0053] The stick feeding mechanism, the stick straightening mechanism, the bar material clamping mechanism and the cutting and unfolding integrated mechanism are arranged in a front-to-back manner.

[0054] The stick delivery mechanism is used to push the stick to the center position of the clamping part of the bar clamping mechanism, and to correct the stick through the stick straightening mechanism before sending it to the center position of the bar clamping mechanism to ensure that the center of the stick is aligned with the center of the bar. The stick delivery mechanism cooperates with the bar clamping mechanism to realize the stick threading operation.

[0055] The stick delivery detection mechanism is used to control the front end position of the stick to ensure the distance between the front end of the stick and the front end of the bar material.

[0056] The feeding mechanism is used to continuously convey the bar materials to the clamping position of the bar material clamping mechanism, and is arranged on the left side of the bar material clamping mechanism.

[0057] The bar material transfer mechanism is used to clamp the exposed rear end part of the skewer after being threaded, and remove the threaded bar from the bar material clamping mechanism by rotating 180° counterclockwise (the bar material clamping mechanism is in an open state at this time), and the bar material length is detected at this position by the bar material length detection mechanism; then the rod material is rotated 180° in the same direction to convey the rod material to a position aligned with the feed port of the integrated cutting and unfolding mechanism, and the threaded bar is unloaded from the bar material transfer mechanism through the pre-expanding and cutting feeding mechanism.

[0058] The pre-cutting and spreading material receiving and feeding mechanism is used to unload the threaded bars on the bar transfer mechanism and convey the bars to the cutting position of the cutting and spreading integrated mechanism.

[0059] The integrated cutting and spreading mechanism is used to realize the bisection of the bar material 9 and the spreading after bisection, and finally realize the output of the formed bar material.

[0060] The above functional mechanisms can specifically adopt the following structural forms:

[0061] The visa agency

[0062] The sign delivery mechanism mainly includes a sign bin and a sign pushing mechanism. The sign bin 5.3 is used to store signs. The sign bin is supported and fixed to the upper end of the support plate 5.1 of the material platform as a whole. It is mainly composed of a storage section located at the upper part and a vertical feeding channel located at the lower part. The storage section can be composed of, but not limited to, a shell with an open left end and two vertical baffles vertically and parallelly fixed to the left opening position of the shell as shown in the attached figure. The vertical feeding channel can be a flat vertical channel composed of four sides, namely, the front, rear, left and right sides, as shown in the attached figure. A feeding port is provided at the bottom of the vertical feeding channel. The width of the feeding port is slightly larger than the diameter of the sign, ensuring that only one sign can pass through at a time. Since there are a large number of signs in the sign bin, an accumulation is formed in the sign bin, in order to ensure that the signs are smoothly discharged from the feeding port according to the set production efficiency. A stick loosening mechanism is provided on the left side of the vertical feeding channel near the upper position to prevent the upper sticks from exerting too much squeezing force on the lower sticks and preventing the sticks from falling smoothly. At the same time, an auxiliary stick lowering mechanism is provided on the right side of the vertical feeding channel near the lower position to exert downward force on the sticks near the lower part. The cooperation between the stick loosening mechanism and the auxiliary stick lowering mechanism ensures the smooth feeding of the sticks.

[0063] The above-mentioned stick release mechanism adopts two coaxially arranged stick release wheels 5.2, and teeth are arranged on the outer circumferential surface of the stick release wheels. The stick release wheels are driven by a stick release motor 5.7 and a chain transmission mechanism to drive the two stick release wheels to rotate counterclockwise, and the teeth exert an upward pushing force on the sticks in the aligned position to loosen the sticks.

[0064] The auxiliary stick-feeding mechanism uses a plurality of coaxial stick-feeding wheels 5.6. The stick-feeding wheels and the stick-releasing wheels can use the same set of driving mechanisms, and the driving mechanisms drive the plurality of stick-feeding wheels to rotate counterclockwise, exerting a downward pushing force on the sticks near the feeding port.

[0065] The stick pushing mechanism is used to receive the sticks that fall from the discharge port of the vertical discharge channel, and push the sticks forward, so that the sticks are straightened by the stick straightening mechanism, and then enter the center position of the clamping part of the bar material clamping mechanism and stop at the set position. The stick pushing mechanism adopts a gear rack transmission mechanism, including a stick pushing rack 5.5, a rack guide support frame, and a stick pushing gear 5.4. The stick pushing gear is arranged below the stick pushing rack, and the stick pushing gear is driven by a stick pushing motor. The upper part of the stick pushing gear is meshed with the teeth arranged at the lower part of the stick pushing rack. The stick pushing rack is driven to move forward and backward by the rotation of the stick pushing gear. The stick pushing rack is slidably supported on the rack guide support frame in the front-to-back direction. Specifically, the rack guide support frame can adopt a square support frame with a slot in the middle of the upper end. The rack guide support frame is fixed on the silo support plate in the front-to-back direction at a position below the silo discharge port. The rack for pushing the sign is embedded in the inner cavity of the rack guide support in a manner that the upper end thereof extends out from the slot at the upper end of the rack guide support frame. Several groups of guide rollers arranged front and back are vertically installed on the left and right sides of the rack for pushing the sign. The guide rollers cooperate with the inner cavity of the rack guide support frame to form a guide support along the front-back direction, which realizes the supporting function of the rack for pushing the sign on the one hand and the front-back guiding function of the rack for pushing the sign on the other hand. A lower concave surface is arranged at the front end of the upper end of the rack for pushing the sign, and the sign pushed forward is supported by the lower concave surface, and the previous pushing force is applied to the sign by the rear side surface of the lower concave surface (in the present invention, the rear side surface is preferably an inclined surface), so that the sign and the rack for pushing the sign move forward synchronously.

It mainly includes an upper clamping component 3.2, a lower clamping component 3.3, a clamping drive mechanism 3.4 and a clamping base 3.1. The clamping base is used to realize the centralized assembly of the upper clamping component, the lower clamping component and the clamping drive mechanism according to the designed position, and to realize the installation of the entire bar material clamping mechanism on the frame.

The V-shaped clamping opening on the upper clamping head and the V-shaped clamping opening on the lower clamping part are arranged in an upward and downward manner. When the upper clamping member and the lower clamping member move relative to each other to a closed position, the centering clamping of the bar material is achieved through the upper and lower V-shaped clamping openings. The clamping length of the upper clamping assembly and the lower clamping assembly for the bar material should reach the length covering the entire bar material. In addition, in order to achieve a larger clamping area for the bar material, the upper clamping head and the lower clamping head both adopt a combined structure. Specifically, they both include an intermediate clamping head piece integrally formed with the corresponding clamping arm and one or more front clamping pieces connected to the front side by bolts and one or more rear clamping pieces connected to the rear side. The multiple clamping heads at the lower end of each clamping arm are arranged in the opposite direction of the V-shaped clamping opening. The V-shaped clamping openings of the multiple clamping pieces on the upper clamping member and the V-shaped clamping openings of the multiple clamping pieces on the corresponding lower clamping member are arranged in an opposite direction one by one.

[0075] The clamping drive mechanism is used to drive the upper clamping assembly and the lower clamping assembly to move in opposite directions to achieve clamping of the bar. The clamping drive assembly adopts a gear rack meshing mechanism driven by a cylinder, and mainly includes a clamping drive cylinder 3.4.1, a push plate 3.4.5, a rod guide plate 3.4.2 and multiple groups of clamping drive units. Each group of clamping drive units mainly includes a first rack

[0076] 3.4.8, a second rack 3.4.7, two transmission gears 3.4.9, a connecting block 3.4.6, a vertical guide rod 3.4.3 and a compression spring 3.4.4. The first rack and the second rack are respectively arranged on the inner side of the upper clamping arm and the inner side of the lower clamping arm, and can be formed in an integral structure with the corresponding clamping arm, or a split fixed combination structure. The two transmission gears are arranged between the two racks in an upper and lower manner, and both form tooth meshing with the two racks. The connecting block is fixedly connected to the lower clamping arm in the horizontal direction, and a vertical through hole is arranged on the right side of the lower clamping arm on the connecting block, and the vertical guide rod is limited upward and is installed in the vertical through hole in a clearance fit manner. The compression spring is sleeved on the vertical guide rod, and a spring limiting portion is arranged in the upper middle position of the vertical guide rod, which contacts the upper end of the compression spring to limit the upper end of the compression spring.

[0077] A cylinder bracket 3.1.2 is fixed to the right upper end of the clamping base, and the clamping drive cylinder is vertically fixed on the cylinder bracket with the cylinder rod facing downward. The lower cylinder rod end of the clamping drive cylinder is fixedly connected to the upper end of the push plate, which is used to drive the push plate to move up and down. A plurality of rod holes are arranged on the lower horizontal plate portion of the cylinder push plate along the front-to-back direction, and the cylinder push plate is respectively connected with the vertical guide rods of multiple groups of clamping drive units through the plurality of rod holes, and the lower horizontal plate portion of the cylinder push plate is arranged between the bottom of the compression spring and the top of the plurality of connecting blocks, and contacts with the lower end of the compression spring to limit the lower end of the compression spring.

[0078] When the rod of the clamping drive cylinder is extended, the connecting block is pressed down by the push plate, and the connecting block transmits power to the lower clamping part, and the lower clamping part moves downward. Through the meshing of the second rack-gear-first rack, the power is transmitted to the upper clamping part at the same time, and the upper clamping part is synchronously driven upward to realize the opening of the bar clamping mechanism. In the open state, the loading mechanism can be used to load the material. When the rod of the clamping drive cylinder is retracted, the pressure of the spring drives the lower clamping part upward and the upper clamping part downward. In this way, according to the cross-sectional dimensions of different parts of the bar, the upper clamping parts and the lower clamping parts at various locations can realize the shape-conforming centering clamping, which can meet the clamping of bars of the same diameter and bars of different diameters at various parts, and can achieve a better clamping effect.

[0079] The bar material transfer mechanism

[0080] It is used to rotate the stick-shaped food on the skewer counterclockwise 180° from the clamping position to the rod length detection mechanism position to detect the length of the rod. It mainly includes a rotating drum 8.1, an elastic clamping block 8.4, and a rotating drum driving mechanism. The front end of the rotating drum is rotatably supported on the front supporting plate of the rotating drum, and the rear end of the rotating drum is rotatably supported on the rear supporting plate 8.5 of the rotating drum. The rotating drum driving mechanism is arranged on the rear side of the rear supporting plate of the rotating drum. The rotating drum driving mechanism can adopt a meshing transmission mechanism of a small gear 8.8 and a large gear 8.7 driven by a servo motor 8.6. The small gear is driven by a servo motor, and the servo motor is fixedly installed on the motor mounting plate on the rear side of the rear supporting plate of the rotating drum. The large gear is coaxially fixedly connected to the rear end of the rotating drum. Two front and rear support plates are coaxially fixed on the drum at the front side of the rear support plate of the drum, which are marked as 8.2 and 8.3 in the attached drawings respectively. Two elastic clamping blocks are fixed radially outward at two positions set at 180° near the edge of the front and rear support plates, and the two elastic clamping blocks on the front support plate correspond to the two elastic clamping blocks on the rear support plate one by one along the front-to-back direction, and each corresponding two elastic clamping blocks constitute a group of clamping components. The elastic clamping blocks are radially processed with an S-shaped bending elastic arm part 8.4.1 and a hook-shaped fixed arm part 8.4.2, and an elastic clamping groove 8.4.3 with a hole opening to one side is formed between the outer end of the elastic clamping arm and the hook fixed arm. When a group of clamping components rotates to the top position, the two clamping blocks are respectively located at the front and rear positions of the upper and lower straightening blocks with a set gap, and the clamping grooves of the two clamping blocks are aligned with the straightening channels on the straightener. When the stick feeding mechanism pushes the stick forward, the stick passes through the clamping groove through the front part. When the stick is pushed forward and in place, the back part of the stick is clamped by the clamping grooves of the two clamping blocks. As the drum rotates, the stick and the bar material on the stick are transferred from the stick insertion position to the bar length detection position in sequence. The bar length detection mechanism detects the bar length, and then rotates 180°. During the rotation, the material is unloaded.

[0081] The feeding mechanism before cutting and spreading mainly includes a material receiving bent plate 11.1, a material receiving bent plate swinging drive mechanism, a rear end clamping block 11.3, a feeding rack 11.4, a feeding gear 11.9, a feeding drive motor 11.5, a material unloading cam 11.8, a material unloading swing arm 11.7, etc.

[0082] The material receiving bent plate is used to hold the bar material at the front end of the feeding port of the integrated expansion and cutting mechanism, and is driven to swing at a certain angle by the material receiving bent plate swing driving mechanism, and the material receiving bent plate driving mechanism includes a driving rod 11.2, a transmission chain 11.12, a first transmission sprocket 11.10, a second transmission sprocket 11.11, a driving swing arm 11.13 and a driving cam 11.14. The front end of the driving rod is fixedly connected with the upper part of the material receiving bent plate, and the rear part of the driving rod is installed on the rear support plate at the rear of the drum and is located on the right side of the large gear at the rear of the drum. The first transmission sprocket is fixedly installed at the rear end of the driving rod, and the second transmission sprocket is installed on the rear side of the rear support plate. The driving cam is coaxially installed with the large gear, and the upper end of the driving swing arm is hinged to the rear side of the rear support plate, and the right side of the driving swing arm contacts the outer surface of the driving cam.

[0083] The rear end clamping block 11.3 of the skewer is composed of a clamping block body 11.3.1 and two clamping pieces 11.3.2 embedded in the front end of the clamping block body and symmetrically arranged on the left and right. The two clamping pieces are arranged in an eight-shaped shape with the wide mouth facing backwards. A clamping groove 11.3.4 is formed between the two clamping pieces, an upper stopper 11.3.3 is arranged at the upper part of the clamping groove, and an eight-shaped guide opening is arranged at the lower part of the clamping groove to guide the rear end of the skewer into the upper clamping groove. The clamping block structure ensures that the rod material for the skewer can only be transported to the front end. The upper end of the rear end clamping block of the skewer is fixedly connected to the front end of the feed rack, and the feed rack passes through the rear support plate and meshes with the lower part of the feed gear, and the feed gear is driven by the feed drive motor.

[0084] The unloading cam is fixedly installed on the rotating drum and is located on the front side of the rear support plate. The upper end of the unloading swing arm is connected to the bottom of the straightening block bracket through an elastic hinge 11.6. The left side of the unloading swing arm is in contact with the outer surface of the unloading cam. A unloading stop convex is provided on the right side of the unloading swing arm. The unloading stop convex applies a downward force to the rear end of the skewer close to the rod material, so that the rod material can fall smoothly after being threaded through the skewer.

[0085] When the rod material is passed through the skewer, the upper end of the skewer is guided into the clamping groove by the action of the upper end stop block in the clamping groove, and the rear end of the skewer falls off from the opening position of the elastic clamping groove on the rear elastic clamping block under the action of the unloading swing arm, and the position of the skewer close to the rod material falls off from the opening position of the elastic clamping groove on the front elastic clamping block, so that the skewer rod material is unloaded from the rod material transfer mechanism as a whole, and the unloaded rod material is received by the rod material receiving bent plate; then, as the feeding rack moves forward, the skewer rod material is pushed to the center position of the cutting material.

[0086] The delivery distance detection mechanism:

[0087] Used to control the distance that the pick is pushed forward, see the figure, mainly including the first guide rod 6.6, the detection rod 6.8, the first sensor fixing frame 6.5, the first magnetic block 6.2, the first sensor 6.4, the first detected part 6.3 and the detection transmission rack 6.1. The first guide rod is guided and supported on the vertical plate below the front end of the material table support plate and the first guide rod bracket fixed on the upper end of the frame in the front-to-back direction. The front end of the first guide rod is fixed with an upward support plate 6.7, and a detection rod extending backward is fixed at the upper end of the support plate in the front-to-back direction. The rear end of the detection rod is the detection contact end. The rear end of the first guide rod is fixedly installed with the first sensor fixing frame. The first sensor fixing frame adopts a metal frame. The first sensor is fixed at the lower part of the first sensor fixing frame in the front-to-back direction. The detection distance of the first sensor is 1-2mm. The first magnetic block is fixedly installed on the side of the detection transmission rack and is arranged opposite to the front and back of the upper part of the first sensor fixing frame. The detection transmission rack is slidably mounted on the rack guide rail in the front-to-back direction, and the rack guide rail is fixedly mounted on the support frame below the material table support plate in the front-to-back direction. The detection transmission rack is provided with meshing teeth on the upper part, which mesh with the lower part of the push-sign gear through the meshing teeth. The first detected part is fixedly mounted below the first magnetic block and aligned with the detection head of the first sensor in the front-to-back direction.

[0088] In the initial state of pushing the stick, the entire stick distance detection mechanism is in the front end position. At this time, the first magnetic block and the first sensor fixing frame are attracted, and the distance between the first sensor and the first detected part is within the distance detection range of the first sensor. In the process of pushing the stick, in the front stage of pushing the stick, the detection transmission rack drives other structural parts to move backward under the action of the stick pushing gear. When the rear end of the detection rod contacts the front end of the bar material, it is subjected to the resistance of the bar material and overcomes the suction between the first sensor fixing frame and the first magnetic block. The first guide long rod, the detection rod, the first sensor fixing frame and the first sensor stop moving backward, while the first magnetic block and the first detected part continue to move backward under the drive of the detection transmission rack, resulting in the disappearance of the detection signal of the first sensor. The control system of the processing equipment calculates the distance between the front end of the stick and the front end of the bar material from the moment when the signal of the first sensor disappears, and controls the number of revolutions of the stick pushing motor through the distance to realize the detection of the stick distance. When the front end of the bamboo stick reaches the front end of the bar material, the bar material clamping mechanism is released, and the stick is pushed forward continuously until the stick is completely out of the bin.

[0089] The bar length detection mechanism:

[0090] It is used to detect the length of the bar material, and mainly includes a second guide rod 7.1, a second sensor fixing frame 7.4, a second magnetic block 7.6, a second sensor 7.5, a second detection member 7.7, a detection transmission rack, a front baffle 7.2 and a rear baffle 7.3. The detection transmission rack is the same as the detection transmission rack of the above-mentioned delivery distance detection mechanism.

[0091] The second long guide rod is guided and supported along the front-to-back direction on the vertical plate below the front end of the material table support plate and on the second guide rod bracket fixed at the upper end of the frame. On the second long guide rod, an upward front baffle and a rear baffle are vertically fixedly installed at a set distance in front and back. The rear end of the second long guide rod is fixedly installed with the second sensor fixing frame. The second sensor fixing frame adopts a metal frame. The second sensor is fixed along the front-to-back direction at the lower part of the second sensor fixing frame. The detection distance of the second sensor is 1-2mm. The second magnetic block is fixedly installed on the side of the transmission rack for detection, and is arranged front and back opposite to the upper part of the second sensor fixing frame. The second detected part is fixedly installed below the second magnetic block, and is aligned front and back with the detection head of the second sensor.

[0092] In the initial state, the entire bar length detection mechanism is at the front end position. At this time, the second magnetic block is attracted to the second sensor fixing frame, and the distance between the second sensor and the second detected part is within the distance detection range of the second sensor. At this time, the front end of the bar that has been pierced with the sign and rotates to the bottom with the drum is located behind the front baffle, and the rear end of the sign contacts the front end surface of the rear baffle; as the sign feeding mechanism enters the sign pushing process, driven by the detection transmission rack, the entire bar length detection mechanism moves backward. Under the action of the front baffle, the pierced bar moves backward as a whole. When the rear end of the bar contacts the front end of the elastic clamping block on the front side of the corresponding position, the bar is limited, causing the second guide rod, the second sensor fixing frame, the second sensor, the front baffle and the rear baffle to stop moving backward, while the second magnetic block and the second detected part continue to move backward under the drive of the detection transmission rack. Subsequently, in the process of the push rack moving backward and resetting, the detection transmission rack moves forward in the opposite direction, pushing the rear end of the sign through the rear baffle, so that the bar at the rod length detection position moves forward and resets.

[0093] The detected value of the bar length is used by the control system to control the cutting position of the bar and the movement process of the unfolding after calculation.

Specifically, the lower end of the cutter arm can adopt a round head, and a vertical slot is provided on the cutter seat. The width of the vertical slot matches the diameter of the round head of the cutter arm, and the round head of the cutter arm is inserted into the vertical slot in a manner that it can move and rotate up and down.

The slider guide support plate frame is fixed between the front side plate and the rear side plate of the cutting and unfolding part support frame and is located below the cam group. It is composed of an upper guide bracket 2.5.5 and a lower guide bracket 2.5.6. The upper guide bracket and the lower guide bracket are provided with slider guide grooves in an upward and opposite manner. The upper ends and lower ends of the plurality of sliders are respectively inserted into the slider guide grooves in a manner of being slidable up and down, so as to play a guiding and supporting role for the sliders.
