Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, and in particular relates to a cutting device and a shearing machine. Background Technology

[0002] In the industrial processing of sausage skewers, the cutting machine is a key piece of equipment for separating the sausages from each other. Its core function is to precisely cut off the knots on the sausage skewer. Existing cutting machines mainly use a double-scissor mechanism, which separates the sausages by cutting the front and rear ends of the knots.

[0003] However, in actual production scenarios, after the sausage skewers are processed and shaped, both ends of the sausage are prone to deformation. When the cutting machine detects the position of the two ends before and after the knots, the sensor often deviates from the deformed part due to the deformation of the sausage ends. This causes the scissors mechanism to frequently cut into the deformed part of the sausage during the cutting action, resulting in blade jamming or the knots not being cut off smoothly, seriously affecting the continuity of production and work efficiency. Moreover, being in this abnormal working state for a long time will subject the scissors mechanism to additional impact and wear, greatly shortening its service life and increasing equipment maintenance costs. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a cutting device, comprising:

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0044] In this embodiment of the invention, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part of a structure. They can be mechanical or electrical connections. They can be direct connections or indirect connections through an intermediate medium, and can represent the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention based on the specific circumstances.

[0045] like Figures 1 to 8 As shown, this utility model embodiment provides a cutting device, including a conveying mechanism, a cutter 200, a scissor mechanism 300, an adjusting mechanism 400, and a second motor 500. The cutting device also includes a mounting frame 600, on which the scissor mechanism 300 and the adjusting mechanism 400 are both mounted.

[0046] like Figure 1 and 2 As shown, the conveying mechanism includes two belt conveyor assemblies 100 arranged at an upper and lower interval, and a conveying channel 800 is formed between the two belt conveyor assemblies 100. The conveying channel 800 is used to convey sausage skewers. The sausage skewers include multiple sausages 700 and knots 720. Both ends of the sausages 700 have deformable portions 710. The deformable portions 710 on the opposite ends of two adjacent sausages 700 are connected by knots 720.

[0047] The conveying mechanism is provided in three intervals along the conveying direction of the sausage skewer to form a first gap 810 and a second gap 820. Specifically, the first gap 810 is located upstream of the second gap 820.

[0048] The cutter 200 corresponds to the first gap 810, and its axis is parallel to the conveying direction of the sausage string. A part of the cutter 200 can extend into the first gap 810. The cutter 200 can rotate around its axis to cut the deformed part 710 connected to the rear end of the knot 720. Specifically, the second motor 500 is mounted on the second mounting base 510, and its output shaft is fixedly connected to the cutter 200 to drive the cutter 200 to rotate around its axis.

[0049] The scissor mechanism 300 corresponds to the second gap 820. The output end of the scissor mechanism 300 extends into the second gap 820. The nodule 720 has a cutting position for the scissor mechanism 300 to cut. The distance between the cutting position and the front end of the nodule 720 is 2mm to 5mm.

[0050] It should be understood that the cutting device is also equipped with a detection device (not shown in the figure), such as a light sensor or a vision detection device. These two detection devices correspond to the first gap 810 and the second gap 820, respectively. The detection device corresponding to the first gap 810 is used to detect the rear end of the nodule 720, and the detection device corresponding to the second gap 820 is used to detect the cut position of the nodule 720. Because the detection device is easily affected by the deformable part 710 connected to it when detecting the rear end of the nodule 720, the detection position may deviate from the deformable part 710. The high-speed rotation of the cutter 200 can directly cut off part of the deformed portion 710, so that the rear end of the knot 720 is separated from the sausage 700, avoiding situations such as blade jamming or incomplete cutting. The cutting position setting can prevent the scissor mechanism 300 from cutting the deformed portion 710 connected to the front end of the knot 720. The cooperation between the cutter 200 and the scissor mechanism 300 can make the overall structure of the cutting device simpler, reduce manufacturing costs, reduce waste of raw materials, greatly improve work efficiency, and extend service life.

[0051] In one embodiment, such as Figure 3 As shown, the scissor mechanism 300 includes a blade 310, a blade holder 320, a drive assembly 340, and a transmission structure 350. The two blade holders 320 are arranged vertically and crosswise, and the intersection of the two blade holders 320 is connected by a rotating shaft 332. Specifically, the scissor mechanism 300 also includes a fixed base 330, which is provided with mounting holes 331. The rotating shaft 332 is located at the mounting holes 331, and the two first mounting seats 410 pass through the mounting holes 331 and are rotatably connected to the rotating shaft 332. More specifically, the fixed base 330 is fixed to one side of the mounting bracket 600.

[0052] One end of the tool holder 320 is detachably provided with a blade 310 to facilitate the replacement and maintenance of the blade 310 and reduce the operating cost of the equipment. Specifically, a limiting groove 131 (not shown in the figure) is provided on the opposite surface of the two tool holders 320. The blade 310 is limited in the limiting groove 131 by a fastener (not shown in the figure). The fastener is preferably a bolt. The blade 310 is fixed by the cooperation of the limiting groove 131 and the fastener, which facilitates subsequent disassembly, assembly, maintenance and replacement.

[0053] Each blade holder 320 is connected to a transmission structure 350 at the other end. The drive assembly 340 can drive the two transmission structures 350 to drive the corresponding blade holder 320 to move up and down in a cross motion, so that the two blades 310 can cut the cutting position on the nodule 720. It should be noted that the front end of the blade 310 extends into the first gap 810. When the two blades 310 open, the sausage 700 can pass through the open space.

[0054] Furthermore, the two blades 310 are provided with two opposing cutting edges on their opposite sides, so that both blades 310 can perform cutting when moving up and down in a cross motion, thereby improving work efficiency.

[0055] In one embodiment, such as Figure 1 and 3 As shown, the transmission structure 350 includes a connecting seat 351, a first connecting rod 352 and a second connecting rod 353. The middle part of the first connecting rod 352 is rotatably connected to the connecting seat 351, and the two ends are rotatably connected to the other end of the tool holder 320 and one end of the second connecting rod 353, respectively.

[0056] Furthermore, the drive assembly 340 includes a first motor 341 and a crankshaft 342, wherein the crankshaft 342 is connected to the output shaft of the first motor 341, and the crankshaft 342 has two eccentric shafts 343 that are rotatably connected to corresponding second connecting rods 353, and the two eccentric shafts 343 are symmetrical about the crankshaft 342.

[0057] That is, the crankshaft 342 is driven to rotate by the first motor 341, and the corresponding second connecting rod 353 is driven by the two eccentric shafts 343 on the crankshaft 342 to drive the corresponding first connecting rod 352 to move up and down in a cross motion, so as to drive the corresponding tool holder 320 to move up and down in a cross motion, making the movement of the blade 310 more stable and reliable, and ensuring the cutting accuracy and effect.

[0058] In one embodiment, such as Figure 5 As shown, baffles are provided on both sides of the conveying channel 800 to limit the movement of the sausage 700 and ensure the stability of the conveying of the sausage 700.

[0059] In one embodiment, such as Figure 1 and 5 As shown, each conveying mechanism is connected to an adjustment mechanism 400. The adjustment mechanism 400 can drive the two belt conveyor assemblies 100 to move in opposite or opposite directions, thereby adjusting the distance between the two belt conveyor assemblies 100, that is, adjusting the height of the conveying channel 800, so as to adapt to the conveying of sausages 700 of different sizes.

[0060] In some specific embodiments, such as Figure 5As shown, the adjustment mechanism 400 includes a vertically arranged lead screw 420, which can rotate around its axial direction. Two threaded layers 421 with opposite helical directions are arranged on the lead screw 420 at intervals. Nut seats 430 are matched on the threaded layers 421. The two belt conveyor assemblies 100 are respectively connected to the corresponding nut seats 430. That is, the rotation of the lead screw 420 drives the belt conveyor assemblies 100 on the two nut seats 430 to move relative to or away from each other, so as to realize the adjustment of the height of the conveying channel 800, which has the advantage of high precision.

[0061] In some specific embodiments, such as Figure 5 As shown, the adjustment mechanism 400 also includes a spring 441 and a vertically arranged guide rod 440. The guide rod 440 passes through the two nut seats 430 and is movably connected to the nut seats 430. Specifically, there are two guide rods 440 spaced apart along the conveying direction. The arrangement of the guide rods 440 can improve the stability of the belt conveyor assembly 100 movement.

[0062] Furthermore, spring 441 is sleeved on guide rod 440. Spring 441 can drive one nut seat 430 to move towards the other nut seat 430. That is, by utilizing the elastic force of spring 441, one of the belt conveyor components 100 can have a certain clamping force, which can avoid damage to sausage 700 and improve conveying efficiency.

[0063] In some specific embodiments, such as Figure 5 As shown, the adjustment mechanism 400 also includes a first mounting base 410 and a handle 450. The two ends of the lead screw 420 are rotatably connected to the first mounting base 410, and the two ends of the guide rod 440 are fixedly connected to the first mounting base 410 to ensure the stability of the installation of the lead screw 420 and the guide rod 440. The upper end of the spring 441 abuts against the third fixed base 330, and the lower end abuts against the nut seat 430 located above, so that the belt conveyor assembly 100 above has a certain clamping force.

[0064] The handle 450 is located at the upper end of the lead screw 420, which means that the user can adjust the distance between the two belt conveyor assemblies 100 by operating the handle 450, making operation convenient.

[0065] The nut seat 430 has a socket 431 on the side facing the belt conveyor assembly 100. The belt conveyor assembly 100 has a plug rod 111 that matches the socket 431. Specifically, there are at least two sockets 431 to ensure the stability of the belt conveyor assembly 100. The cooperation between the socket 431 and the plug rod 111 facilitates the disassembly and assembly of the belt conveyor assembly 100, which is convenient for cleaning the belt conveyor assembly 100 and improves cleaning efficiency.

[0066] In one embodiment, such as Figure 6 and7 As shown, the belt conveyor assembly 100 includes a frame 110, pressure rollers 120, and a conveyor belt 130. It should be noted that the insertion rod 111 is set on the frame 110. Furthermore, the two pressure rollers 120 are respectively set at both ends of the frame 110, and the conveyor belt 130 surrounds the two pressure rollers 120. One of the pressure rollers 120 has a connecting shaft 121 on the side facing the nut seat 430. The nut seat 430 is rotatably set with a connector 432 corresponding to the connecting shaft 121. The end of the connector 432 facing the connecting shaft 121 has a square connecting hole 433. The end of the connecting shaft 121 facing the connector 432 is adapted to the connecting hole 433.

[0067] Furthermore, the other end of the connector 432 is connected to a coupling 140. Specifically, the coupling 140 is a telescopic universal coupling 140, so that the two belt conveyor assemblies 100 can still work after being adjusted up and down.

[0068] Furthermore, the other end of the coupling 140 is connected to a transmission rod 150, which passes through the mounting frame 600 and is rotatably connected to the mounting frame 600 via a bearing. A transmission wheel 160 is provided at the end of the transmission rod 150 away from the coupling 140. The conveying mechanism also includes a third motor 180, which is mounted on the mounting frame 600. A drive wheel 181 is provided on the output shaft of the third motor 180. The drive wheel 181 is connected to the transmission wheel 160 on each belt conveyor assembly 100 via a transmission belt 170, so that the third motor 180 can drive each conveyor belt 130 to rotate synchronously.

[0069] It should be further explained that a limiting groove 131 is provided in the middle of the conveyor belt 130 along its winding path. The limiting groove 131 is adapted to the sausage 700 to further limit the sausage 700 and improve the stability of the conveying.

[0070] This utility model also provides a cutting machine, including the cutting device in any of the above embodiments.

[0071] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
