Description

Technical Field

[0001] This invention belongs to the field of food processing technology, specifically relating to an integrated processing device for cutting and spreading skewered stick-shaped food. Background Technology

[0002] Gluten skewers and ham sausages are common skewered barbecue snacks on the market. Before grilling, these skewers generally need to be sliced ​​or cut in half to increase their thorough cooking. The half-cutting method involves creating staggered cuts on both sides of the skewer. Current staggered cutting methods for skewers involve placing the stick-shaped food on a simple cutting device and slicing it one by one. The center of the sliced ​​food is then manually skewered. During the slicing process, each stick is manually placed in and the cutting blades on both sides of the device are operated. After each slice, the cut stick is removed before the next skewer can be cut. After slicing, the stick is then manually stretched along the skewer to a certain length.

[0003] Cutting and unfolding are two important steps in the processing of stick-shaped foods. The existing two-step processing method with manual positions has problems such as high labor requirements, low production efficiency, and unstable forming quality. Therefore, it is necessary to design a device that can perform cutting and unfolding in one machine after stick-shaped foods are skewered. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated processing equipment for cutting and spreading skewered stick-shaped food that can save labor, improve production efficiency, and ensure the quality of forming.

[0005] The above-mentioned objective of this invention is achieved through the following technical solution:

[0006] A cutting and unfolding integrated processing device for skewered stick-shaped food products enables the cutting of the stick material and its subsequent unfolding from front to back, resulting in the output of the shaped stick material. The device includes a feeding mechanism, a frame, a cutting mechanism, and an unfolding mechanism. The unfolding and cutting mechanisms are mounted on the frame in an vertical arrangement. The cutting mechanism includes a left cutting blade assembly, a right cutting blade assembly, and a blade-closing drive mechanism. The left and right cutting blade assemblies are symmetrically arranged. Each assembly consists of a cutting blade support, a cutting blade shaft, and multiple sets of cutting blade units arranged sequentially. The cutting blade shaft is fixedly supported on the frame along the front-to-back direction. The cutting blade support is rotatably connected to the cutting blade shaft, and the upper part of each cutting blade unit is connected to the cutting blade support. The blade-closing drive mechanism drives the left and right cutting blade assemblies to rotate synchronously around their corresponding cutting blade shafts, achieving blade closure. The cutting blade units of the left and right cutting blade assemblies correspond one-to-one and are unfolded sequentially from front to back via the unfolding mechanism.

[0007] The feeding mechanism is located at the rear of the frame and includes a material support part and a pusher part. The material support part is used to support the bar stock; the pusher part is used to clamp the rear end of the center tag of the bar stock and push the tagged bar stock to the center position of the cut. After the bar stock is cut, the bar stock is unfolded from front to back in sequence by pushing the tag forward and the cutting unit.

[0008] Furthermore, the frame is composed of a front side plate, a rear side plate, and a bottom plate; the cutter shaft is rotatably supported on the front and rear side plates; the cutter bracket is provided with shaft mounting holes along the front-rear direction, and the cutter bracket is fixedly connected to the cutter shaft through the shaft mounting holes; the cutter bracket is composed of multiple cutter arm support blocks arranged front and rear, each cutter arm support block corresponding to a set of cutter units, and each cutter arm support block is provided with a cutter arm slot; each set of cutter units includes a cutter arm, a cutter seat, and a cutter body, and the cutter body is provided with a V-shaped cut; the upper end of the cutter arm is inserted into and fixedly connected to the cutter arm slot of the corresponding cutter arm support block; the lower end of the cutter arm is engaged with the cutter seat in a vertically movable and rotatable manner, and the cutter body is fixedly installed on the inner side of the cutter seat; the multiple cutter units on the left cutter assembly and the multiple cutter units on the right cutter assembly are arranged one-to-one with the V-shaped cuts facing each other;

[0009] Furthermore, the blade closing drive mechanism includes two sets of horizontal drive units, left and right; each set of horizontal drive units includes a blade closing drive cylinder and a blade closing push plate; the blade closing push plate is located on the outside of the cutter seat, the blade closing drive cylinder is located on the outside of the blade closing push plate, and the cylinder rod end of the blade closing drive cylinder is drivenly connected to the outside of the blade closing push plate.

[0010] Furthermore, the blade unfolding mechanism includes a cam group, a cam group drive mechanism, a slider group, and a slider guide support frame. The cam group consists of multiple unfolding cams arranged coaxially front and rear, with their cam heights staggered along the circumferential direction. These cams are fixed to the same camshaft. The camshaft is rotatably supported on the front and rear side plates of the frame via bearings and is driven to rotate by the cam group drive mechanism.

[0012] 1. This invention uses a feeding structure to push the tagged bar stock to the center of the cutting process. At the center, the bar stock is cut by the combined action of multiple sets of cutting units on the left and right. After the bar stock is cut, the unfolding mechanism drives multiple sets of cutting units to open sequentially from front to back. With the forward push of the tagged bar, the cut bar stock is unfolded sequentially from front to back, realizing integrated cutting and unfolding of the bar stock. Compared with the existing manual processing method, this saves manpower, greatly improves processing efficiency, and ensures the uniformity of bar stock unfolding, achieving better product processing quality.

[0019] The structure of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that these embodiments are descriptive and not limiting.

[0020] Please see the following: A cutting and spreading integrated processing equipment for skewered stick-shaped food products. Figures 1-5 Its invention is to realize the cutting of bar stock and the unfolding after cutting, and finally realize the output of shaped bar stock.

[0021] It mainly includes a frame 1, a left cutting blade assembly 3.2, a right cutting blade assembly 3.1, a blade closing drive mechanism 4, a blade unfolding mechanism 2, and a feeding mechanism 5. The left cutting blade assembly and the right cutting blade assembly constitute the cutting mechanism 3, which, together with the blade closing drive mechanism, constitutes the cutting mechanism.

[0022] The blade spreading mechanism and the cutting mechanism are mounted on the frame in an up-down arrangement. The feeding mechanism is located at the rear of the frame and includes a material supporting part and a pusher part. The material supporting part is used to support the bar stock and can adopt, but is not limited to, the material supporting groove structure formed by the material supporting curved plate 5.1 shown in the attached figure. The material supporting curved plate is fixed to the support rod 5.2 along the front-to-back direction, and the support rod is fixed to the frame. The pusher part can adopt, but is not limited to, a gear and rack mechanism, including a pusher rear end clamping component 5.3, a pusher rack 5.4, and a pusher gear 5.5. The gear is driven by a pusher motor (not shown in the attached figure). The pusher gear meshes with the pusher rack, which is mounted on a rack guide frame. The front end of the pusher rack is connected to the pusher rear end clamping component. The pusher rear end clamping component can adopt a pneumatic gripper or other structure that can clamp the end of the stick.

[0023] The frame is mainly composed of a front side plate 1.1.1, a rear side plate 1.1.2, and a bottom plate 1.1.3. The left and right cutter assemblies are symmetrically arranged. Both the left and right cutter assemblies consist of a cutter bracket 3.1.2, a cutter shaft 3.1.1, and multiple cutter units. The cutter shaft is fixedly supported on the front and rear side plates. The cutter bracket is provided with a shaft mounting hole along the front-rear direction, and the cutter bracket is rotatably connected to the cutter shaft through the shaft mounting hole. The cutter bracket is composed of multiple cutter arm support blocks arranged front and rear, each cutter arm support block corresponding to a set of cutter units, and each cutter arm support block is provided with a cutter arm slot. Each cutter unit includes a cutter arm 3.1.3, a cutter seat 3.1.4, and a cutter body 3.1.5, and the cutter body is provided with a V-shaped cut. The upper end of the cutter arm is inserted and assembled with the cutter arm slot of the corresponding cutter arm support block to form a fixed connection. The lower end of the cutter arm engages with the cutter holder in a vertically movable and rotatable manner. Specifically, the lower end of the cutter arm can have a round head. A vertical slot is provided on the cutter holder, the width of which matches the diameter of the round head of the cutter arm. The round head of the cutter arm is inserted into the vertical slot in a vertically movable and rotatable manner. The cutter body is fixedly installed on the inner side of the cutter holder. Multiple cutter units on the left cutter assembly correspond one-to-one with multiple cutter units on the right cutter assembly in a V-shaped cut. Guide plates 4.1 are provided on the front and rear sides of the cutter holders of the left and right cutter units to guide the cutter holders.

[0024] The blade-closing drive mechanism drives multiple sets of cutting blade units on the left to rotate counterclockwise around their corresponding cutting blade axes and multiple sets of cutting blade units on the right to rotate clockwise around their corresponding cutting blade axes. The V-shaped cuts on both sides intersect, achieving blade closing. During blade closing, the bar stock positioned in the middle is cut. The blade-closing drive mechanism includes two sets of horizontal drive units; each set includes a blade-closing drive cylinder 4.3 and a blade-closing push plate 4.2. The blade-closing push plate is located on the outside of the cutting blade holder, and the blade-closing drive cylinder is located on the outside of the blade-closing push plate. The cylinder rod end of the blade-closing drive cylinder is connected to the outside of the blade-closing push plate. By extending the cylinder rods of the two blade-closing drive cylinders, the corresponding blade-closing push plate is pushed inward, which in turn pushes the cutting blade holder inward, ultimately pushing the cutting blade itself inward to achieve the cutting of the bar stock.

[0025] The blade unfolding mechanism is used to synchronously and sequentially open the left and right cutting units from the front end to the rear end. During the opening process, it cooperates with the feeding rack of the pre-cutting feeding mechanism to push the skewer in the center of the bar stock forward, realizing the sequential unfolding of the cut bar stock from front to back. The blade unfolding mechanism mainly includes a cam group 2.4, a cam group drive mechanism, a slider group 2.7, and a slider guide support frame. The cam group consists of multiple unfolding cams arranged coaxially front and rear, with the cam heights staggered along the circumferential direction. The multiple unfolding cams are fixed on the same camshaft. The camshaft is rotatably supported on the front and rear side plates of the frame by bearings and is driven to rotate by the cam group drive mechanism. The cam group drive mechanism consists of a cam drive motor 2.1 and transmission gears. The cam drive motor is fixed to the front or rear side plate, and a transmission gear 2.2 is fixedly installed at the output end of the cam drive motor. Another transmission gear 2.3 is fixedly installed at one end of the camshaft, and the two transmission gears mesh with each other. The slider assembly is located directly below the cam assembly. The slider assembly consists of multiple sliders arranged front and rear, each corresponding to a cam for deployment. The slider guide support frame is fixed between the front and rear side plates of the frame, located below the cam assembly. It consists of an upper guide bracket 2.5 and a lower guide bracket 2.6. Slider guide grooves are arranged opposite each other on the upper and lower guide brackets. The upper and lower ends of the multiple sliders are slidably inserted into the slider guide grooves, providing guidance and support for the sliders.

[0026] Multiple sliders are arranged in a one-to-one correspondence with the cutter arm support blocks on both sides in the left-right direction. Each slider has meshing teeth on both the left and right sides, and the cutter arm support blocks on both sides have meshing teeth on the inner side. The meshing teeth on both sides of the slider mesh with the meshing teeth on the cutter arm support blocks at the corresponding positions.

[0027] Both the left and right cutter bodies are supported on the base plate of the frame. To prevent the cutter bodies from swaying during movement and thus ensure cutting quality, an upper limit plate 7 and a lower limit plate 8 are provided. The upper end of the upper limit plate is fixed to a horizontal fixing plate 6 located below the lower guide bracket. The horizontal fixing plate is fixed horizontally between the front and rear side plates of the frame. The lower end of the upper limit plate has limiting teeth that insert into the gaps between the left and right cutter bodies, limiting the upper part of the cutter body and eliminating gaps between them. The lower end of the lower limit plate is vertically fixed to the base plate of the frame, and the upper end of the lower limit plate has limiting teeth that insert into the gaps between the left and right cutter bodies, limiting the lower part of the cutter body and eliminating gaps between them.

[0028] The working principle of this invention is as follows:

[0029] This integrated processing equipment for skewering and cutting stick-shaped food can be used as a standalone unit or as a rear-end unit in a fully automatic stick-shaped food forming machine. Combined with the front skewering equipment, it forms an integrated processing unit for skewering, cutting, and unfolding the stick-shaped food. During the cutting process, the skewered sticks are fed to the center of the cutting position via a feeding mechanism. Simultaneously, the cylinder rods of the two-sided blade drive cylinders extend, driving the left and right cutting units to rotate inwards (closer to the cutting center) around their corresponding axes, cutting the stick-shaped food. After cutting, the feeding mechanism pushes the rear of the skewer forward, and the cam drive motor starts, driving the cam assembly to rotate. From front to back, the highest point of the cam contacts the corresponding slider below, pushing the slider downwards. The slider, through tooth meshing, transmits power to the cutting units on both sides, causing them to swing outwards simultaneously, opening the stick-shaped food. As the cutting units open, the skewer moves the opened portion of the stick-shaped food forward, unfolding the food.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
