Description

Technical Field

[0002] In the industrial processing of sausage strings, the shearing machine is the key equipment to separate the sausages from each other. Its core work is to accurately cut the knots on the sausage string. The existing shearing machine mainly adopts a double scissors mechanism to separate the sausages by cutting the front and back ends of the knot.

[0003] However, in actual production scenarios, after the sausage string is processed and formed, the two ends of the sausage are very likely to deform. When the shearing machine detects the front and rear ends of the nodule, the position detected by the sensor often deviates from the deformed part due to the deformation of the two ends of the sausage. As a result, the scissors mechanism frequently mistakenly cuts the deformed part of the sausage when performing the cutting action, resulting in knife jamming or the nodule cannot be cut smoothly, seriously affecting the continuity of production and affecting work efficiency. Moreover, if it is in this abnormal working state for a long time, the scissors mechanism will be subjected to additional impact and wear, which greatly shortens its service life and increases the equipment maintenance cost.

[0045] like Figures 1 to 8 As shown, an embodiment of the present invention provides a cutting device, including a conveying mechanism, a cutter 200, a scissors mechanism 300, an adjustment mechanism 400 and a second motor 500. The cutting device also includes a mounting frame 600, and the scissors mechanism 300 and the adjustment mechanism 400 are both arranged on the mounting frame 600.

[0046] like Figure 1 and 2 As shown, the conveying mechanism includes two belt conveying assemblies 100 spaced apart from each other, and a conveying channel 800 is formed between the two belt conveying assemblies 100. The conveying channel 800 is used to convey the sausage string. The sausage string includes a plurality of sausages 700 and nodules 720. Both ends of the sausages 700 have deformation portions 710, and the deformation portions 710 on the opposite ends of two adjacent sausages 700 are connected by a nodule 720.

[0047] Three conveying mechanisms are arranged at intervals along the conveying direction of the sausage string 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] Among them, the cutter 200 corresponds to the first gap 810, and its axial direction is parallel to the conveying direction of the sausage string. Part of the cutter 200 can extend into the first gap 810, and the cutter 200 can rotate around its axial direction to cut the partial deformed portion 710 connected to the rear end of the nodule 720. Specifically, the second motor 500 is arranged on the second mounting seat 510, and its output shaft is fixedly connected to the cutter 200 to drive the cutter 200 to rotate around its axial direction.

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

[0050] It should be understood that the cutting device is also provided with a detection device (not shown in the figure), such as a light sensor or a visual detection device, and the 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-off position of the nodule 720. Since the detection device is easily affected by the deformation part 710 connected thereto when detecting the rear end of the nodule 720, the detection position deviates to the deformation part 710, and 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 nodule 720 is separated from the sausage 700, which can avoid the occurrence of situations such as knife jamming or uncutting. The setting of the cutting position can prevent the scissors mechanism 300 from shearing the deformed portion 710 connected to the front end of the nodule 720. The cooperation of the cutter 200 and the scissors mechanism 300 can make the overall structure of the cutting device simpler, the manufacturing cost lower, and can reduce the waste of raw materials, which can greatly improve work efficiency and increase service life.

[0051] In one embodiment, if Figure 3 As shown, the scissors mechanism 300 includes a blade 310, a blade seat 320, a drive assembly 340 and a transmission structure 350, wherein the two blade seats 320 are cross-arranged up and down, and the intersection of the two blade seats 320 is connected by a rotating shaft 332. Specifically, the scissors mechanism 300 also includes a fixed seat 330, a mounting hole 331 is provided on the fixed seat 330, and the rotating shaft 332 is arranged at the mounting hole 331. The two first mounting seats 410 pass through the mounting hole 331 and are rotatably connected with the rotating shaft 332. More specifically, the fixed seat 330 is fixed to one side of the mounting frame 600.

[0052] A blade 310 is detachably provided at one end of the knife holder 320 to facilitate replacement and maintenance of the blade 310 and reduce the use cost of the equipment. Specifically, limiting grooves 131 (not shown in the figure) are provided on the opposite surfaces of the two knife holders 320, and 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 is convenient for subsequent disassembly, maintenance and replacement.

[0053] The other end of each knife holder 320 is connected to a transmission structure 350. The driving assembly 340 can drive the two transmission structures 350 to drive the corresponding knife holders 320 to move up and down crosswise, so that the two blades 310 can shear 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 are opened, the sausage 700 can pass through the open space.

[0054] Furthermore, two blades disposed up and down and facing each other are arranged on the back sides of the two blades 310, so that the two blades 310 can both perform shearing when they move crosswise up and down, thereby improving work efficiency.

[0055] In one embodiment, if 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, wherein the middle portion 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 knife seat 320 and one end of the second connecting rod 353 respectively.

[0056] Furthermore, the driving 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 rotatably connected to corresponding second connecting rods 353 , and the two eccentric shafts 343 are symmetrical about the axis of the crankshaft 342 .

[0057] That is, the crankshaft 342 is driven to rotate by the first motor 341, and the two eccentric shafts 343 on the crankshaft 342 further drive the corresponding second connecting rod 353 to drive the corresponding first connecting rod 352 to move up and down crosswise, so as to drive the corresponding knife holder 320 to move up and down crosswise, so that the movement of the blade 310 is more stable and reliable, and the cutting accuracy and effect are guaranteed.

[0058] In one embodiment, if Figure 5 As shown, blocking bars are provided on both sides of the conveying channel 800 to limit the position of the sausage 700 and ensure the stability of the conveying of the sausage 700.

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

[0060] In certain specific embodiments, such as Figure 5As shown, the adjustment mechanism 400 includes a vertically arranged screw rod 420, wherein the screw rod 420 can rotate around its axis, and has two thread layers 421 with opposite spiral directions spaced apart above and below, and the thread layers 421 are matched with nut seats 430, and the two belt conveyor assemblies 100 are respectively connected to the corresponding nut seats 430, that is, the belt conveyor assemblies 100 on the two nut seats 430 are driven by the rotation of the screw rod 420 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 certain specific embodiments, such as Figure 5 As shown, the adjustment mechanism 400 also includes a spring 441 and a vertically arranged guide rod 440, wherein the guide rod 440 passes through the two nut seats 430 and is movably connected to the nut seats 430. Specifically, two guide rods 440 are arranged at intervals along the conveying direction. The arrangement of the guide rod 440 can improve the stability of the movement of the belt conveyor assembly 100.

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

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

[0064] The handle 450 is disposed at the upper end of the screw rod 420 , that is, the user can adjust the distance between the two belt conveyor assemblies 100 by operating the handle 450 , which is convenient to operate.

[0065] A socket 431 is provided on the side of the nut seat 430 facing the belt conveyor assembly 100, and an insertion rod 111 matching the socket 431 is provided on the belt conveyor assembly 100. Specifically, at least two sockets 431 are provided to ensure the stability of the belt conveyor assembly 100. The cooperation between the socket 431 and the insertion rod 111 facilitates the disassembly and assembly of the belt conveyor assembly 100, so as to facilitate the cleaning of the belt conveyor assembly 100 and improve the cleaning efficiency.

[0066] In one embodiment, if Figure 6 and7 As shown, the belt conveyor assembly 100 includes a frame 110, a belt pressure roller 120 and a conveyor belt 130. It should be noted that the insertion rod 111 is arranged on the frame 110. Furthermore, the two belt pressure rollers 120 are arranged at both ends of the frame 110. The conveyor belt 130 is surrounded by the two belt pressure rollers 120. A connecting shaft 121 is arranged on the side of one of the belt pressure rollers 120 facing the nut seat 430. A connecting head 432 corresponding to the connecting shaft 121 is rotatably arranged on the nut seat 430. A square connecting hole 433 is arranged on one end of the connecting head 432 facing the connecting shaft 121, and one end of the connecting shaft 121 facing the connecting head 432 is adapted to the connecting hole 433.

[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 through a bearing.
