Description

Technical Field

[0001] This utility model relates to the field of sausage filling technology, and in particular to a clamping structure and a sausage filling device. Background Technology

[0002] Sausages, a popular food, rely on a series of automated equipment for industrial production, including filling, twisting, and segmentation. Among these, the performance of the equipment used in the tying and twisting process after filling directly determines the product's quality, appearance, and production efficiency.

[0003] Currently, sausage filling equipment on the market generally suffers from the following problems in the twisting process: Traditional clamping structures have poor adaptability when dealing with casings of different materials, thicknesses, or filler consistency. Due to structural limitations, the clamping force is often not precisely controlled, and the synchronization of the movement of the two clamping nozzles is difficult to guarantee. This leads to problems in actual production, such as insufficient clamping and ineffective twisting for sausages with a thinner filling; while for delicate casings, excessive clamping force or uneven force can easily cause them to break, resulting in product scrap and raw material waste.

[0004] Therefore, how to solve the problems of poor synchronization of the clamping mouthpiece and easy damage to the casing is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a clamping structure to solve the problems of poor clamping synchronization and easy damage to the casing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A clamping structure for a sausage filling device, comprising: frame; The clamping assembly includes a first clamping mouth and a second clamping mouth. The first end of the first clamping mouth and the first end of the second clamping mouth are both rotatably mounted on the frame. The second end of the first clamping mouth and the second end of the second clamping mouth are respectively provided with a first clamping part and a second clamping part.

The second end of the first swing arm is rotatably disposed in the middle of the first clamping mouth, and the second end of the second swing arm is rotatably disposed in the middle of the second clamping mouth. In this process, based on the rotation of the rotating drive component, the first swing arm and the second swing arm drive the first clamp and the second clamp to rotate along the first direction and the second direction respectively. The first direction and the second direction are opposite to each other, so as to realize the closing and opening of the clamping space.

[0010] Optionally, in the above-mentioned clamping structure, the first clamping mouth and the second clamping mouth are respectively provided with a first arc-shaped guide groove and a second arc-shaped guide groove, and the frame is provided with a first guide block that slides with the first arc-shaped guide groove and a second guide block that slides with the second arc-shaped guide groove.

[0011] A sausage filling apparatus, comprising: A rotary filling mechanism is used to fill raw materials into sausage casings; The clamping structure, as described above, is located at the discharge end of the rotary filling structure and is used to clamp the filled sausage. The winding device is mounted on the frame of the clamping structure and located between the frame and the clamping assembly of the clamping structure. It is used to wind the sausage after it has been clamped by the clamping structure. The segmented traction structure is located on the side of the clamping assembly of the clamping structure away from the winder, and is used to segment and traction transport the wound sausage.

[0012] Optionally, in the above-mentioned sausage filling device, the rotary filling structure includes: A support frame and a rotating plate, wherein the rotating plate is rotatably mounted on the support frame; At least two filling tubes are arranged sequentially along the circumference of the rotating plate and extend along the axial direction of the rotating plate; A rotary drive unit is mounted on a support frame, and the rotation output end of the rotary drive unit is connected to a rotary plate to drive the rotary plate to rotate intermittently so that each filling tube rotates to the filling station in sequence. A fixed precision tube, with its outlet end corresponding to the filling station and its inlet end connected to the feed pump, is used to seal and connect with the inlet end of the filling tube when the filling tube rotates to the filling station. A moving drive is used to drive the rotating plate to move along its axial direction so that the filling tube rotated to the filling station can be docked or separated from the precision tube.

[0013] Optionally, in the sausage filling device described above, the rotary filling structure further includes a return pipe and a pushing mechanism; The return pipe is connected to the precision pipe and is used to temporarily store the residual raw materials in the precision pipe after filling is completed; The material pushing mechanism is located on the return slurry pipe and is used to push the residual raw materials in the return slurry pipe into the precision pipe.

[0014] Optionally, in the sausage filling device described above, the feeding mechanism includes a push rod and a piston. The piston can slide inside the return pipe under the push of the push rod.

[0015] Optionally, in the sausage filling device described above, the segmented traction structure includes a segmented base plate, a pair of segmented belts, a pair of segmented adjustment plates, a segmented drive assembly, and a segmented adjustment assembly; Each segmented belt is set on the segmented base plate by its corresponding segmented adjustment plate.

[0016] This utility model provides a clamping nozzle structure, which has the following advantages compared with the prior art: In the clamping structure provided by this utility model, a rotating drive (such as a motor) drives the first and second swing arms to reciprocate. Since the first and second swing arms are respectively hinged to the middle of the first and second clamping mouths, the swing of the swing arms is directly converted into the two clamping mouths rotating in opposite directions or in opposite directions around their rotation fulcrum, thereby realizing the closing and opening of the clamping space and completing the clamping and releasing of the sausage. When the rotating drive rotates in the forward direction, the first and second clamping mouths rotate in opposite directions, the first clamping mouth rotates counterclockwise and the second clamping mouth rotates clockwise, and the clamping space opens, allowing the sausage to pass through. When it is necessary to clamp the sausage, the rotating drive rotates in the reverse direction. Driven by the two swing arms, the first clamping mouth rotates clockwise and the second clamping mouth rotates counterclockwise, closing the clamping space to clamp the sausage located in the clamping space. At the same time, in conjunction with the operation of the winding device, the clamped sausage can be wound with thread. After the winding is completed, the clamps open under the drive of the rotating drive component to allow the sausage to proceed to the next process.

[0017] The opening and closing degree of the clamping nozzle can be controlled by controlling the output angle of the rotary drive, thereby controlling the clamping force. This allows it to adapt to casings of different materials, thicknesses, and meat consistency, ensuring a firm grip while completely eliminating the risk of tearing the casing. Furthermore, since the same rotary drive is used to drive the two clamping nozzles, it ensures that the two clamping nozzles move synchronously when closed.

[0018] The sausage filling device provided by this utility model has the above-mentioned clamping structure, and therefore has all the technical effects of the above-mentioned clamping structure, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0021] The present invention will be described below through specific embodiments. Those skilled in the art will understand that the specific embodiments below are merely illustrative and do not limit the scope of the present invention in any way. Furthermore, in the following embodiments, unless otherwise specified, the reagents and equipment used are commercially available. If specific processing conditions and methods are not explicitly described in the later embodiments, conditions and methods known in the art can be used for processing.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. The embodiments of this application are only examples, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper," "lower," "top surface," "bottom surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] like Figure 1As shown, this utility model discloses a clamping structure for a sausage filling device, comprising: a frame 101; a clamping assembly, the clamping assembly including a first clamping nozzle 102 and a second clamping nozzle 103, the first ends of the first clamping nozzle 102 and the first ends of the second clamping nozzle 103 being rotatably mounted on the frame 101, and the second ends of the first clamping nozzle 102 and the second clamping nozzle 103 respectively having a first clamping portion and a second clamping portion, forming a clamping space between the first clamping portion and the second clamping portion for sausages to pass through; and a driving assembly, the driving assembly including a rotation driving member 104, a first swing arm 105 and a second swing arm 106. The first end of the first swing arm 105 and the first end of the second swing arm 106 are rotatably mounted on the rotation drive member 104 and are symmetrically mounted on both sides of the rotation drive member 104. The second end of the first swing arm 105 is rotatably mounted in the middle of the first clamping mouth 102, and the second end of the second swing arm 106 is rotatably mounted in the middle of the second clamping mouth 103. Based on the rotation of the rotation drive member 104, the first swing arm 105 and the second swing arm 106 drive the first clamping mouth 102 and the second clamping mouth 103 to rotate along the first direction and the second direction, respectively. The first direction and the second direction are opposite to each other, so as to realize the closing and opening of the clamping space.

[0025] In the clamping structure provided by this utility model, the rotation drive 104 (such as a motor) drives the first swing arm 105 and the second swing arm 106 to reciprocate. Since the first swing arm 105 and the second swing arm 106 are respectively hinged to the middle of the first clamping mouth 102 and the second clamping mouth 103, the swing of the swing arm is directly converted into the two clamping mouths rotating towards or away from each other around their rotation fulcrum, thereby realizing the closing and opening of the clamping space and completing the clamping and releasing of the sausage. When the rotation drive 104 rotates in the forward direction, the first clamping mouth 102 and the second clamping mouth 103 rotate in the first direction and the second direction, which are opposite to each other. The first clamping mouth 102 rotates counterclockwise and the second clamping mouth 103 rotates clockwise, opening the clamping space, which allows the sausage to pass through. When it is necessary to clamp the sausage, the drive unit 104 rotates in the opposite direction. Driven by the two swing arms, the first clamp 102 rotates clockwise and the second clamp 103 rotates counterclockwise, closing the clamping space to clamp the sausage located in the clamping space. At the same time, in conjunction with the operation of the winding device 200, the clamped sausage can be wound with thread. After the winding is completed, driven by the renewed forward rotation of the drive unit 104, the clamps open to allow the wound sausage to proceed to the next process.

[0026] The opening and closing degree of the clamping nozzle can be controlled by controlling the output angle of the rotating drive 104, thereby controlling the magnitude of the clamping force. This allows it to adapt to casings of different materials, thicknesses, and meat consistency, ensuring a firm grip while completely eliminating the risk of tearing the casing. Furthermore, since the same drive unit is used to drive the two clamping nozzles, it ensures that the two clamping nozzles can move synchronously when closed.

[0027] To optimize the above technical solution, based on the same rotating drive 104 driving the two clamping jaws to ensure synchronous movement of the clamping jaws, a synchronization component is provided, including: a first clamping jaw pulley 107 disposed at one end of the first clamping jaw 102 near the first clamping part; a second clamping jaw pulley 108 disposed at one end of the second clamping jaw 103 near the second clamping part; and a rotating output wheel 110 disposed on the frame 101 near the first end of the first clamping jaw 102 and the first end of the second clamping jaw 103, with the rotating output wheel 110 arranged on the first... Between the clamping mouth 102 and the second clamping mouth 103; a tensioning wheel 111 is slidably disposed on the frame 101, the sliding direction of the tensioning wheel 111 is from the clamping space toward the rotary output wheel 110, and the tensioning wheel 111 is connected to the frame 101 through an elastic element so that the tensioning wheel 111 always has the tendency to tension the tensioning belt 109; the tensioning belt 109 is sequentially wound around the first clamping mouth pulley 107, the tensioning wheel 111, the second clamping mouth pulley 108 and the rotary output wheel 110 to form a closed-loop transmission system.

[0028] When the rotation drive assembly drives the two clamps to open and close, the distance between the first clamp pulley 107 and the second clamp pulley 108 set on the two clamps will change. The tension pulley 111 will slide automatically under the action of the elastic element to compensate for this distance change in real time, ensuring that the tension belt 109 is always in a taut state, thereby forcing the two clamp pulleys to rotate synchronously and in opposite directions, ensuring the synchronicity of the clamp movement.

[0029] Furthermore, a tension adjustment plate is provided on the tension wheel 111, and an installation groove is provided on the frame 101. The tension adjustment plate is slidably disposed in the installation groove of the frame 101, and an elastic element is disposed between the tension adjustment plate and the inner wall of the installation groove, so that the tension wheel 111 always has a tendency to move close to the rotating output wheel 110.

[0030] exist Figure 1 In this configuration, the tension adjusting plate on the tension wheel 111 is subjected to an upward pulling force from the tension belt 109 and a downward elastic force from the elastic element. When the clamping space needs to be opened to allow the sausage to pass through, the rotating drive 104 drives the first swing arm 105 and the second swing arm 106 to swing, causing the first clamp 102 and the second clamp 103 to rotate in opposite directions. This movement drives the tension wheel 111 upward through the tension belt 109 (i.e., towards the clamping space), overcoming the elastic force of the elastic element and compressing the elastic element between the inner wall of the mounting groove and the adjusting plate. This movement allows the first clamp 102 and the second clamp 103 to rotate in opposite directions, thereby opening the clamping space.

[0031] When the sausage needs to be clamped, the first clamp 102 rotates clockwise and the second clamp 103 rotates counterclockwise. The distance between the two clamp pulleys shortens, and the belt tends to loosen. At this time, the elastic force exerted on the adjusting plate by the elastic element compressed between the inner wall of the mounting groove and the adjusting plate is greater than the tension of the belt on the adjusting plate. Under the elastic force of the elastic element, the adjusting plate moves downward, i.e., towards the direction closer to the rotating output wheel 110. It should be noted that in order to maintain the elastic element always exerting a downward force on the adjusting plate and to ensure that the tensioning wheel 111 always tends to tension the tensioning belt 109, the elastic element is always in a compressed state between the adjusting plate and the inner wall of the mounting groove.

[0032] In the actual sausage production process, it is necessary not only to clamp the sausage but also to twist it. In one embodiment of this utility model, a rotating output wheel 110 is rotatably mounted on the frame 101, and the rotation of the rotating output wheel 110 drives the tension belt 109 to rotate. After the two clamps clamp the sausage, the rotating output wheel 110 can be driven to rotate by an external motor. The rotating output wheel 110 synchronously drives the first clamp pulley 107 and the second clamp pulley 108 to rotate through the tension belt 109. Because the sliding direction of the tension wheel 111 is from the clamping space toward the rotating output wheel 110, the tension wheel 111, the rotating output wheel 110, and the sausage clamped in the clamping space are on the same straight line. When the clamping space is closed, the outer circumferential surface of the tension belt 109 directly contacts and clamps the sausage passing through the clamping space. The rotation of the rotating output wheel 110 drives the sausage to roll, thus achieving the twisting of the sausage.

[0033] This embodiment creatively sets the clamping nozzle structure to be rotatable and integrates synchronization and twisting drive, so that the structure can immediately drive the sausage to rotate and twist after completing the clamping action, without the need for sausage transfer or activation of additional complex mechanisms. It achieves efficient integration and seamless connection of the two major functions of "clamping" and "twisting" in the same simple structure, which greatly optimizes the process flow, shortens the operation cycle, and improves the overall production efficiency.

[0034] To ensure the smoothness and precision of the gripper assembly during rotation, a first arc-shaped guide groove 112 and a second arc-shaped guide groove 113 are respectively formed on the first gripper 102 and the second gripper 103. A first guide block and a second guide block, which slide in conjunction with the arc-shaped guide grooves, are fixed on the frame 101. This structure precisely constrains the rotation trajectory of the gripper assembly, preventing it from swaying. The design of the guide grooves and guide blocks ensures the stability of the gripper's movement and prevents deviation. This is particularly important in production, as it reduces wear and failure rates.

[0035] This embodiment provides a sausage filling device, which mainly includes a rotary filling structure 300, a clamping structure, a winding device 200, and a segmented traction structure 400, the positional relationship of which is as follows: Figure 4As shown. The rotary filling structure 300 is used to continuously and residue-free fill raw materials into sausage casings; the clamping structure is set at the discharge end of the rotary filling structure 300 and is used to clamp and twist the filled sausages; the winding device 200 is set on the frame 101 of the clamping structure and is located between the frame 101 and the clamping assembly, and is used to tie the twisted sausages with thread; the segmented traction structure 400 is set on the side of the clamping assembly of the clamping structure away from the winding device 200, and is used to segment and traction the tied sausages to form the final product.

[0036] In the entire sausage filling device, the clamping nozzle structure, as the clamping execution component, works in conjunction with the continuous feeding of the rotary filling structure 300, the precise wire binding of the winding device 200, and the fixed-length conveying of the segmented traction structure 400 to form a complete automated production line, thereby improving the automation level and production adaptability of the whole machine.

[0037] The rotary filling structure 300 mainly includes a support frame 303, a rotating plate 304, at least two filling tubes 301, a rotary drive unit 302, a precision tube 307, and a moving drive component (such as a cylinder). The rotating plate 304 is rotatably mounted on the support frame 303 via bearings. At least two filling tubes 301 are evenly arranged circumferentially along the rotating plate 304 and extend axially (i.e., in the filling direction). The rotary drive unit 302 (such as a motor with a reducer) has its rotation output end connected to the rotating plate 304, driving the rotating plate 304 to rotate intermittently, causing each filling tube 301 to rotate sequentially to a fixed filling position. The precision tube 307 is fixed, with its inlet end connected to a feed pump (such as a vacuum vane metering pump) and its outlet end precisely corresponding to the filling position.

[0038] A moving drive unit is used to drive the rotating plate 304 to move axially. When a filling tube 301 rotates to the filling station, the moving drive unit pushes the rotating plate 304, causing the inlet end of the filling tube 301 to seal and connect with the outlet end of the precision tube 307, after which filling can begin. After filling is completed, the moving drive unit pulls the rotating plate 304 back to its original position, separating the filling tube 301 from the precision tube 307. Then, the rotation drive unit 302 operates, causing another filling tube 301 to rotate to the filling station to continue the filling process. This design allows for continuous production by having one filling tube 301 be casingd while another is in the stop position.

[0039] Furthermore, a return pipe 305 and a pushing mechanism are provided, with the return pipe 305 connected to the feed end of the precision tube 307. When the filling pipe 301 separates from the precision tube 307, the raw material remaining in the precision tube 307 and the connecting pipe will flow into the return pipe 305 for temporary storage due to gravity or backflow, preventing it from solidifying and clogging inside the precision tube 307. The remaining material is then pushed back into the precision tube 307 by the pushing mechanism to participate in a new round of filling, avoiding material waste.

[0040] Specifically, the feeding mechanism includes a push rod 306 and a piston. The piston, connected to the output end of the push rod 306, extends into the return pulp pipe 305. The piston has a tapered portion and at least one sealing groove to enhance sealing. Before the next filling begins, the push rod 306 pushes the piston upwards within the return pulp pipe 305, pushing the temporarily stored residual meat back into the precision pipe 307, thus achieving raw material recycling and keeping the pipeline clean.

[0041] like Figure 3 As shown, the segmented traction structure 400 is used for segmenting and conveying shaped sausages. Its channel width can be precisely and conveniently adjusted, offering wide adaptability. It mainly includes a segmented base plate 404, a pair of segmented belts 401, a pair of segmented adjusting plates 402, a segmented drive assembly (such as a motor), and a segmented adjusting assembly. The two segmented belts 401 are each mounted on the segmented base plate 404 via a segmented adjusting plate 402, and are symmetrically arranged along a preset plane on the segmented base plate 404, forming a segmented channel for the sausage to pass through. The segmented drive assembly drives the segmented belts 401 to rotate, thereby pulling the sausage forward by friction.

[0042] The segmented adjustment assembly is the core component for adjusting the channel width, and it includes an adjustment handle 403 and an adjustment screw. The adjustment handle 403 is fixedly mounted on the end of the adjustment screw to facilitate the operator's application of force. The adjustment screw is connected to two segmented adjustment plates 402 via a screw-nut pair. Specifically, the adjustment screw has two sections of threads with opposite directions of rotation (e.g., one left-handed and one right-handed), which respectively engage with the nuts fixed on the two segmented adjustment plates 402. The extension direction of the adjustment screw is parallel to the direction in which one of the pair of segmented belts 401 points to the other, that is, parallel to the width direction of the segmented channel.

[0043] When the adjusting handle 403 is rotated, the rotational motion is converted into linear motion via the lead screw and nut pair. This drives the two segmented adjusting plates 402 to move synchronously towards or away from each other along the guide structure on the segmented base plate 404, thereby causing the two segmented belts 401 to move closer or further apart, thus adjusting the width of the segmented channel. This design allows the structure to quickly adapt to the production of sausages of different diameters, effectively preventing "sausage bursting" due to insufficient gaps or segment failure due to excessive gaps, greatly enhancing the versatility of the equipment and the stability of product quality.

[0044] The filling device provided by this utility model improves filling efficiency. The dual-tube rotation enables uninterrupted filling, reducing downtime and improving product quality. The direct filling and return pipe ensure accurate filling weight and prevent clogging. The combination of the clamping structure and the segmented traction structure 400 reduces the risk of sausage breakage and enhances the adaptability of the device. The clamping force of the clamping nozzle is adjustable, and the segment spacing is adjustable, making it suitable for various casings and meat materials.

[0045] It should be noted that the above-mentioned elastic element can be a spring, torsion spring, or other structure with elastic function. In this embodiment of the present invention, the above-mentioned elastic element is a spring.

[0046] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
