A sausage threader

Abstract

This invention belongs to the technical field of food processing equipment, and particularly relates to a sausage untying device, comprising an inner sleeve, a take-up member, and a thread guide. The inner sleeve is hollow, with a discharge port and a feed port at each end. The take-up member and the thread guide extend away from the feed port and are exposed relative to the discharge port. Both the take-up member and the thread guide are eccentrically positioned relative to the inner sleeve. Multiple take-up members are spaced apart around the axis of the inner sleeve, and the distance from the axis of the thread guide to the axis of the inner sleeve is greater than the distance from the axis of the take-up member to the inner sleeve. This invention achieves untying and take-up functions by synchronously rotating the take-up member and the thread guide around the axis of the inner sleeve in a direction opposite to the winding direction of the binding thread, i.e., performing a revolution motion. This removes the binding thread from the sausage and winds it around the take-up member, greatly improving work efficiency and saving labor costs. The untying process does not contact the sausage body, and the sausage surface will not have indentations or tears after untying, significantly improving the finished product qualification rate.

Description

Technical Field

[0001] This invention belongs to the field of food processing equipment technology, and in particular relates to a sausage untying device. Background Technology

[0002] In the production and processing of sausages and other meat products, the filled sausages are usually segmented and tied with thread according to a certain length to form continuous sausages. After subsequent cooking and drying processes, the ties on the sausages need to be removed for packaging or further processing. The removal of sausage ties mostly relies on manual operation, requiring operators to untie the ties one by one. This is labor-intensive, inefficient, and the repetitive nature of the work can easily lead to operator fatigue, affecting production efficiency. Therefore, some sausage tying devices have appeared on the market to improve efficiency. Chinese invention patent CN107089548A discloses a sausage tying device and a sausage processing device using the same, including a frame and a power drive device, a take-up shaft, and a threading / disconnecting frame mounted on the frame. The threading / disconnecting frame has a first slot with a width greater than the diameter of the tying wire but smaller than the diameter of the sausage body. This first slot can be used to thread the wire and disconnect the sausage body. The take-up shaft is used to pull and wind the tying wire around the sausage body to gather the tying wire. The power drive unit can drive the take-up shaft to rotate, so that the binding thread of the sausage body passes through the first slot on the thread-separating frame and is gathered onto the take-up shaft under the traction of the take-up shaft. However, by applying a continuous linear traction force to the binding thread through the rotation of the take-up shaft to pull it out of the sausage, a large relative friction and tensile stress will be generated between the binding thread and the sausage body during the pulling process. Since the cooked sausage body is relatively soft and fragile, this pulling action can easily lead to problems such as tearing of the sausage skin, damage to the meat, or even complete breakage. Summary of the Invention

[0003] The purpose of this invention is to provide a sausage untying device that can solve the above-mentioned problems.

[0004] To achieve the above objectives, an embodiment of the present invention provides a sausage untying device, comprising an inner sleeve, a take-up member, and a thread guide tube. The inner sleeve is hollow and has an outlet and an inlet at its two ends, respectively. The take-up member and the thread guide tube extend away from the inlet and are exposed relative to the outlet. The take-up member and the thread guide tube are eccentrically arranged relative to the inner sleeve. Multiple take-up members are spaced apart around the axis of the inner sleeve. The distance from the axis of the thread guide tube to the axis of the inner sleeve is greater than the distance from the axis of the take-up member to the inner sleeve. The binding thread on the sausage can pass through the thread guide and be confined on one of the take-up members. The take-up member and the thread guide are configured to perform synchronous rotation about the axis of the inner sleeve in a direction opposite to the winding direction of the binding thread, so that the binding thread is wound around the take-up member.

[0005] Optionally, it also includes a first annular turntable and a second annular turntable, both of which are coaxially arranged with the inner sleeve. The first annular turntable is sleeved on the outside of the inner sleeve and rotatably connected to the inner sleeve.

The first spring is sleeved on the shaft, and its two ends abut against the adjusting member and the pressure plate, respectively.

[0008] Optionally, the second annular turntable is provided with a movable hole corresponding to the take-up member. One end of the take-up member near the feed inlet passes through the movable hole and is exposed. The take-up member is rotatably connected to the movable hole. The take-up member can swing inward along the radial direction of the inner sleeve so that the binding wire wrapped on the take-up member can be detached from the take-up member.

[0009] Optionally, it also includes a hollow knob, which is sleeved on the outside of the second annular turntable and rotatably connected to the second annular turntable. The knob can rotate from a first position to a second position around the axis of the inner sleeve. The inner side of the knob is provided with a limiting structure that cooperates with the take-up member. When the knob is in the first position, the limiting structure can limit the take-up member, so that the axis of the take-up member is parallel to the axis of the inner sleeve, or tilted outward along the radial direction of the inner sleeve. When the knob is in the second position, the take-up piece can swing radially inward along the inner sleeve.

[0010] Optionally, the limiting structure is an adjustment groove formed inside the knob, the adjustment groove having a limiting surface and a groove, the distance from the groove to the axis of the second annular turntable being greater than the distance from the limiting surface to the axis of the second annular turntable, and the limiting surface and the groove being connected by an inclined surface.

When the knob is in the first position, the limiting surface and the limiting groove correspond to each other and are in contact with the outer side of the rolling element to limit the swing of the take-up element; When the knob is in the second position, the groove corresponds to the limiting groove, and the two form an active space, allowing the rolling element to move in the direction of the groove.

[0011] Optionally, it also includes a floating ring, wherein the outlet end of the inner sleeve is provided with a connecting seat arranged around its circumference, the floating ring and the connecting seat are spaced apart along the passage direction of the sausage, the floating ring is arranged around the axis of the inner sleeve and is movably connected to the connecting seat through a guide structure, and the floating ring can move toward the connecting seat; A second spring is provided between the floating ring and the connecting seat, and the second spring is used to drive the floating ring to move away from the connecting seat; The connector is equipped with a sensing probe, and a gap is formed between the sensing end of the sensing probe and the floating ring.

[0012] Optionally, the first annular turntable is provided with a protrusion extending in a direction away from the feed inlet, and the extended end of the protrusion is provided with a stepped seat. The stepped seat and the protrusion form a cavity. The first annular turntable is provided with a through hole that passes through the protrusion and communicates with the cavity along its axial direction. A movable shaft is provided in the cavity. One end of the movable shaft extends into the through hole, and the other end passes through the cavity and is exposed. A swing plate perpendicular to its axis is provided at the exposed end of the movable shaft. The thread guide is installed at the end of the swing plate away from the movable shaft. A thread wheel is installed on the swing plate, and the binding thread enters the thread guide through the thread wheel. A limiting rod is provided on the movable shaft, and the limiting rod passes through the movable shaft radially. Two positioning grooves corresponding to the two ends of the limiting rod are opened on the inner wall of the through hole. The positioning grooves extend along the axial direction of the through hole, and the two ends of the limiting rod extend into the corresponding positioning grooves respectively. A support plate is provided on the movable shaft. The support plate is located in the cavity and close to the through hole. A third spring is installed in the cavity. The third spring is sleeved on the movable shaft, and its two ends abut against the support plate and the inner wall of the cavity near the swing plate, respectively.

[0013] Optionally, it also includes a drive mechanism for driving the first annular turntable to rotate about its own axis.

[0014] Compared with existing technologies, the advantages of this invention are: by synchronously rotating the take-up piece and the inner sleeve along their axis in the opposite direction to the winding direction of the binding thread, i.e., by performing a revolution motion, the binding thread on the sausage can be quickly removed, and the binding thread can be wound around the take-up piece, thus realizing the functions of untying and retrieving the thread. This greatly improves work efficiency and effectively saves labor costs. Furthermore, the untying process does not contact the sausage body, and the sausage surface will not have indentations or tears after untying, which can greatly improve the yield rate of finished products.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] like Figures 1 to 3 As shown, this embodiment of the invention provides a sausage untying device, including an inner sleeve 100, a take-up piece 200, a thread guide tube 300, a first annular turntable 400, a second annular turntable 500, a knob 600, a floating ring 700, a drive mechanism 800, and a mounting base 900.

[0035] The inner sleeve 100 is hollow and fixed to the mounting base 900. It has a discharge port 120 and a feed port 110 at its two ends. The sausage enters through the feed port 110 and exits through the discharge port 120. The take-up member 200 and the guide spool 300 extend away from the feed port 110 and are exposed relative to the discharge port 120. Both the take-up member 200 and the guide spool 300 are eccentrically positioned relative to the inner sleeve 100. It should be noted that the take-up member 200 can be parallel to the axis of the inner sleeve 100 or inclined outwards relative to the axis of the inner sleeve 100. Multiple take-up members 200 are spaced apart around the axis of the inner sleeve 100. The distance from the axis of the guide spool 300 to the axis of the inner sleeve 100 is greater than the distance from the axis of the take-up member 200 to the axis of the inner sleeve 100. The binding thread on the sausage can pass through the thread guide 300 and be positioned on one of the take-up parts 200. Specifically, the front end of the take-up part 200 has a V-shaped clamp 220, and one end of the binding thread is clamped and fixed in this clamp 220. The take-up part 200 and the thread guide 300 are configured to rotate synchronously around the axis of the inner sleeve 100 in the opposite direction to the winding direction of the binding thread, so that the binding thread is wound around the take-up part 200, thereby realizing the functions of unwinding and rewinding the thread. This method is highly efficient and can effectively save labor costs.

[0036] like Figure 3 and Figure 5 As shown, in order to achieve synchronous rotation of the thread guide 300 and the take-up piece 200, the sausage unwinding device is equipped with a first annular turntable 400 and a second annular turntable 500. The first annular turntable 400 and the second annular turntable 500 are both coaxially arranged with the inner sleeve 100. The thread guide 300 is installed on the first annular turntable 400, and the take-up piece 200 is installed on the second annular turntable 500 through a connecting shaft.

[0037] The first annular turntable 400 is sleeved on the outside of the inner sleeve 100 and rotatably connected to the inner sleeve 100 via bearings. The second annular turntable 500 is sleeved on the outside of the first annular turntable 400 and rotatably connected to the first annular turntable 400 via bearings. The first annular turntable 400 can drive the second annular turntable 500 to rotate synchronously via the transmission assembly 460. Specifically, the sausage untying device is equipped with a drive mechanism 800 for driving the first annular turntable 400 to rotate around its own axis. Preferably, the drive mechanism 800 includes a motor 810 and a drive gear 820. The drive gear 820 is mounted on the shaft of the motor 810. The outer side of the first annular turntable 400 is provided with a third tooth 480 arranged around its circumference. The drive gear 820 and the third tooth 480 are meshed together. The motor 810 drives the drive gear 820 to drive the first annular turntable 400 to rotate, resulting in high stability.

[0038] Furthermore, such as Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the transmission assembly 460 includes a first gear 461 and a second gear 462. The first gear 461 is eccentrically positioned relative to the first annular turntable 400. The first gear 461 has a shaft portion 4611 extending axially through the first annular turntable 400 and rotatably connected to it via a bearing. The outer side of the inner sleeve 100 has first teeth 130 arranged circumferentially therearound, which mesh with the first gear 461. The inner wall of the second annular turntable 500 has second teeth 530 arranged circumferentially therearound. The second gear 462 is rotatably positioned at the through end of the shaft portion 4611, meshing with the second teeth 530. When the first annular turntable 400 rotates, it can drive the first gear 461 to rotate. Since the first gear 461 meshes with the first tooth pattern 130 formed on the inner sleeve 100, the first gear 461 rotates on its own axis while revolving with the first annular turntable 400. In turn, it drives the second gear 462 to rotate synchronously through the shaft 4611. The second gear 462 then drives the second annular turntable 500 to rotate through the second tooth pattern 530, ensuring that the thread spool 300 and the take-up piece 200 rotate synchronously to complete the unwinding action.

[0039] The second gear 462 transmits torque to the first gear 461 via the overload protection component 470. For example... Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the overload protection assembly 470 includes a first brake pad 471, a second brake pad 472, a pressure plate 473, and a first spring 474. The first brake pad 471 is positioned on the side of the second gear 462 away from the first gear 461 and can rotate together with the second gear 462. The second brake pad 472 is fitted onto the shaft portion 4611 and abuts against the first brake pad 471, and the second brake pad 472 can move axially along the shaft portion 4611. The pressure plate 473 is arranged around the shaft portion 4611 and is located on the side of the second brake pad 472 away from the first brake pad 471. The inner side of the pressure plate 473 is provided with a first cut surface 4731, and the outer side of the shaft portion 4611 is provided with a second cut surface 4612 corresponding to the first cut surface 4731. The first cut surface 4731 and the second cut surface 4612 are in contact, so that the pressure plate 473 can rotate synchronously with the shaft portion 4611. At the same time, the pressure plate 473 can slide along the axial direction. The first cut surface 4731 and the second cut surface 4612 can prevent the pressure plate 473 from rotating.

[0040] The pressure plate 473 abuts against the second brake pad 472. An adjusting element 475 is provided at the end of the shaft 4611 away from the first gear 461. A first spring 474 is sleeved on the shaft 4611, with both ends abutting against the adjusting element 475 and the pressure plate 473 respectively. The adjusting element 475 is preferably a nut, and one end of the first spring 474 abuts against this nut, which is threadedly connected to the shaft 4611. The clamping force of the first spring 474 can be adjusted by adjusting the tightness of this bolt. During operation, when the resistance encountered by the second gear 462 is too great, that is, when the second annular turntable 500 rotates and drives the take-up piece 200 to wind the binding wire, it is subjected to a pulling force exceeding the predetermined limit. At this time, relative sliding occurs between the first brake pad 471 and the second brake pad 472. The power of the first gear 461 cannot be transmitted to the second gear 462, and the second gear 462 will rotate on its own. At this time, the second annular turntable 500 will not be driven to rotate by the second gear 462, thereby playing the role of overload protection and preventing the binding wire from being pulled apart.

[0041] like Figure 5 , Figure 10 and Figure 12 As shown, to facilitate the removal of the binding coil after the binding wire is wound, the second annular turntable 500 is provided with a movable hole 510 corresponding to the take-up member 200. One end of the take-up member 200 near the feed inlet 110 passes through the movable hole 510 and is exposed. The take-up member 200 and the movable hole 510 are rotatably connected by a pin, and the take-up member 200 can swing inward radially along the inner sleeve 100. When the take-up member 200 swings inward, the binding coil wound on it will automatically fall off due to radial contraction, achieving rapid unloading.

[0042] like Figure 5 As shown, to control the swing of the take-up piece 200, a hollow knob 600 is also installed on the sausage untying device. The knob 600 is sleeved on the outside of the second annular turntable 500 and rotatably connected to it. The knob 600 can rotate from a first position to a second position around the axis of the inner sleeve 100. A limiting structure that cooperates with the take-up piece 200 is provided on the inner side of the knob 600. When the knob 600 is in the first position, the limiting structure can limit the take-up piece 200, making its axis parallel to the axis of the inner sleeve 100, or inclined outward along the radial direction of the inner sleeve 100, to ensure that the take-up piece 200 can stably maintain its working posture during winding. When the knob 600 is in the second position, the limiting structure releases the limiting structure from the take-up piece 200, allowing it to swing inward along the radial direction of the inner sleeve 100 to facilitate the removal of the binding thread.

[0043] Specifically, such as Figure 5 , Figure 10 and Figure 12As shown, the limiting structure is an adjustment groove 610 formed inside the knob 600. A limiting surface 611 and a groove 612 are formed on the adjustment groove 610. The distance from the groove 612 to the axis of the second annular turntable 500 is greater than the distance from the limiting surface 611 to the axis of the second annular turntable 500. The limiting surface 611 and the groove 612 are connected by an inclined surface 613. An extension portion 520 extending radially outward is provided on the outer side of the second annular turntable 500. A movable hole 510 is formed on the extension portion 520. A limiting groove 540 corresponding to the movable hole 510 is provided on the outer side of the second annular turntable 500. A rolling element 210 corresponding to the limiting groove 540 is provided on the take-up member 200. Part of the rolling element 210 is accommodated within the limiting groove 540. The rolling element 210 is preferably a wheel or a ball bearing. When the knob 600 is in the first position, the limiting surface 611 corresponds to the limiting groove 540 and contacts the outer side of the rolling element 210. The limiting surface 611 presses the rolling element 210 into the limiting groove 540, thereby restricting the take-up element 200 from swinging radially along the inner sleeve 100. When the knob 600 is in the second position, the groove 612 corresponds to the limiting groove 540, and the two form a movable space. The rolling element 210 can move in the direction of the groove 612, that is, the take-up element 200 can swing freely inward under the action of the binding pressure. The inclined surface 613 allows the rolling element 210 to smoothly transition when the knob 600 switches between the first and second positions.

[0044] It should be noted that a roller 560 is provided on the rear side of the extension 520. Multiple rollers 560 are spaced circumferentially around the second annular turntable 500; in this embodiment, six are preferred. An arc-shaped groove 620 corresponding to the roller 560 is provided on the inner side of the knob 600. The roller 560 is in a rolling connection with the arc-shaped groove 620, allowing the knob 600 to rotate. The rotation range of the knob 600 is limited by the two inner sidewalls of the arc-shaped groove 620 in conjunction with the roller 560, corresponding to the first and second positions.

[0045] like Figure 7As shown, to ensure that the knob 600 can be reset, the sausage untying device is provided with a reset structure 630. Multiple reset structures 630 are spaced apart axially around the second annular turntable 500, preferably six. Specifically, the reset structure 630 includes a first force-bearing protrusion 631, a second force-bearing protrusion 632, and a fourth spring 633. The first force-bearing protrusion 631 is formed on the inner side of the knob 600, and the second force-bearing protrusion 632 is formed on the outer side of the second annular turntable 500. The two ends of the third spring 360 abut against the first force-bearing protrusion 631 and the second force-bearing protrusion 632, respectively. When the knob 600 is rotated from the first position to the second position, the first force-bearing protrusion 631 rotates towards the second force-bearing protrusion 632 and compresses the third spring 360. After the knob 600 is released, the third spring 360 pushes the first force-bearing protrusion 631 to reset the knob 600. Under the force of the third spring 360, the roller 560 can abut against the inner side wall of the arc groove 620. The second annular turntable 500 can drive the knob 600 to rotate through the cooperation between the first force-receiving protrusion 631, the second force-receiving protrusion 632, the third spring 360, the roller 560 and the arc groove 620.

[0046] like Figure 1 , Figure 3 , Figure 4 and Figure 13 As shown, the sausage untying device also includes a floating ring 700. A connecting seat 140 is provided at the outlet end of the inner sleeve 100, circumferentially arranged therearound it. The floating ring 700 and the connecting seat 140 are spaced apart along the direction the sausage passes through. The floating ring 700 is arranged around the axis of the inner sleeve 100 and is movably connected to the connecting seat 140 via a guide structure 720. Specifically, the guide structure 720 includes a guide post 721, a limiting piece 722, and a fastener 723. The guide post 721 is formed on the connecting seat 140 and extends along the axial direction of the inner sleeve 100. The floating ring 700 is provided with a guide hole 740 corresponding to the guide post 721. The guide hole 740 is U-shaped and its opening communicates with the outside. The guide post 721 passes through the guide hole 740, that is, the floating ring 700 can move back and forth towards the connecting seat 140 through the cooperation of the guide post 721 and the guide hole 740. The limiting piece 722 is fixed to the end of the guide post 721 by the fastener 723, which is a screw or bolt, etc. The limiting piece 722 abuts against the side of the floating ring 700 away from the connecting seat 140 to limit the floating ring 700 and prevent the floating ring 700 from falling off.

[0047] A second spring 710 is provided between the floating ring 700 and the connecting seat 140. The second spring 710 is used to drive the floating ring 700 to move away from the connecting seat 140, that is, to press the floating ring 700 against the limiting piece 722. A sensing probe 730 is provided on the connecting seat 140, and a gap is formed between the sensing end of the sensing probe 730 and the floating ring 700. During operation, the sausage passes through the inner sleeve 100 and exits from the floating ring 700. When the binding thread on the sausage is passed through the thread hole and fixed to the take-up piece 200, the binding thread will press against the floating ring 700. Due to the elastic force of the second spring 710, the floating ring 700 is held in a position away from the connecting seat 140, and the sensing probe 730 is not triggered. When the tension of the binding wire is too great during the untying process, the binding wire will push the floating ring 700 to overcome the elastic force of the second spring 710 and move towards the connecting seat 140. When the floating ring 700 approaches the sensing end of the sensing probe 730, the sensing probe 730 is triggered and sends a signal to the control system. The control system can control the rotation speed of the first annular turntable 400, that is, control the speed of the motor 810, thereby avoiding the occurrence of situations such as the binding wire being pulled off.

[0048] Furthermore, such as Figure 3 , Figure 11 and Figure 14 As shown, the first annular turntable 400 has a protrusion 410 extending away from the feed inlet 110. A stepped seat 420 is provided at the extended end of the protrusion 410. The stepped seat 420 and the protrusion 410 form a chamber 430. Specifically, grooves are formed on the opposing surfaces of the stepped seat 420 and the protrusion 410, and the chamber 430 is formed between the grooves on the stepped seat 420 and the protrusion 410. The stepped seat 420 is exposed relative to the front side of the first annular turntable 400. The first annular turntable 400 has a through hole 440 that extends through the protrusion 410 and communicates with the chamber 430 along its axial direction. A movable shaft 320 is provided inside the chamber 430, with one end extending into the through hole 440 and the other end extending through the chamber 430 and exposed. The exposed end of the movable shaft 320 is provided with a swing plate 330 perpendicular to its axis. Specifically, a gap is formed between the swing plate 330 and the exposed end of the take-up member 200. The thread guide 300 is installed at the end of the swing plate 330 away from the movable shaft 320 and is located on the side of the swing plate 330 facing the movable shaft 320. The take-up member 200 is located between the thread guide 300 and the movable shaft 320. A thread pulley 310 is installed on the swing plate 330. Specifically, the thread pulley 310 is located on the side of the swing plate 330 away from the movable shaft 320. The binding thread enters the thread guide 300 through the thread pulley 310, and the thread pulley 310 serves to guide and reduce friction.

[0049] A limiting rod 340 is provided on the movable shaft 320. The limiting rod 340 passes through the movable shaft 320 radially. Two positioning grooves 450 corresponding to the two ends of the limiting rod 340 are opened on the inner wall of the through hole 440. The positioning grooves 450 extend along the axial direction of the through hole 440. The two ends of the limiting rod 340 extend into the corresponding positioning grooves 450 respectively. This structure restricts the circumferential rotation of the movable shaft 320 and only allows it to slide axially. The two positioning grooves 450 form a group. In this embodiment, two groups are provided. The two groups of positioning grooves 450 are spaced apart around the axial direction of the through hole 440, so as to adjust the angle of the swing plate 330. A support plate 350 is provided on the movable shaft 320. The support plate 350 is located inside the chamber 430 and near the through hole 440. A third spring 360 is installed inside the chamber 430 and is sleeved on the movable shaft 320. Its two ends abut against the support plate 350 and the inner wall of the chamber 430 near the swing plate 330, respectively. Under the action of the third spring 360, the movable shaft 320 has a certain floating margin in the axial direction. When the thread spool 300 is subjected to the tension of the binding thread, it can adaptively adjust its position in the axial direction, which plays a buffering role and prevents the binding thread from breaking due to sudden tension changes.

[0050] Furthermore, such as Figure 1 As shown, the sausage untying device also includes a first annular panel 490 and a second annular panel 550. The first annular panel 490 is fixed to the front side of the first annular turntable 400 and has a waist-shaped hole corresponding to the take-up member 200 to facilitate the swinging of the take-up member 200. The second annular panel 550 is fixed to the second annular turntable 500, with the first annular panel 490 located inside the second annular panel 550, forming a gap between them. The second annular panel has a notch for mounting the step seat 420. The floating ring 700 is located inside the first annular panel 490, with a gap between them. The overall structure is neater and more aesthetically pleasing, improving safety and preventing contaminants from flowing into the sausage untying device.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
