Description

Technical Field

[0001] This invention relates to the field of enema twisting equipment technology, and more particularly to a twisting mechanism and enema twisting equipment. Background Technology

[0002] The sausage stuffing and twisting machine is a processing equipment used for stuffing sausages, cured sausages, ham sausages and other types of sausages. Its main function is to quickly and efficiently realize the production and processing of sausages.

[0003] Current sausage stuffing and twisting machines mainly consist of a filling mechanism and a twisting mechanism. The filling mechanism stores and outputs the filling material, while the twisting mechanism includes a conveying pipe and a twisting die. The conveying pipe is connected to the filling mechanism to receive the material output by the filling mechanism, and the twisting die is located at the output port of the conveying pipe. During sausage making, one open end of the casing is fitted onto the conveying pipe, and the knotted end of the casing is fitted onto the outlet of the conveying pipe. When the conveying pipe discharges material, it injects material into the casing. Once the casing has been filled to a predetermined length, the conveying pipe rotates synchronously with the casing. Due to the guide plate (which does not rotate) at the front end, the twisting process, with one stationary and one moving component, forms a twist. The guide wheel guides and conveys the sausage. The injection and twisting steps are then repeated. Generally, a section of casing material can be repeatedly injected and twisted to form multiple sausage sections.

[0004] However, for casings whose shape does not match the feeding tube, they are not tightly fitted to the feeding tube after being put on it, so that the casing cannot rotate synchronously with the feeding tube, resulting in the inability to twist. Summary of the Invention

[0005] In order to solve the technical problem in the prior art that the shape of the sausage casing does not match the conveying pipe, and the casing does not fit tightly with the conveying pipe after being put on, so that the casing cannot rotate synchronously with the conveying pipe, the present invention provides a twisting mechanism and an enema twisting device.

[0006] To address the aforementioned technical problems, in one respect, embodiments of the present invention provide a twisting mechanism connected to a filling mechanism, the twisting mechanism comprising:

[0024] The inner hole is configured such that the total distance from the center of the rotor to both sides of the hole wall along the radial direction of the rotor is the same as the length of the blade, so that the first end and the second end of the blade can remain in close contact with the hole wall during the rotation of the rotor.

[0025] In some embodiments, the hole wall includes a first curved wall surface, a first arcuate wall surface, a second curved wall surface, and a second arcuate wall surface connected in sequence;

[0028] In some embodiments, the blade further has a connecting portion, wherein the first end and the second end are connected to the two ends of the connecting portion, and the width of the connecting portion is smaller than the width of the first end and the second end, so that a notch is formed between the first end and the second end;

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0054] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] In this invention, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0056] One embodiment of the present invention, such as Figures 1 to 5 and Figure 9 As shown, a twisting mechanism is provided, which is connected to a filling mechanism. The twisting mechanism includes a feeding pipe 100, a driving mechanism 200, a twisting mold 300, and a clamping device 400.

[0057] The conveying pipe 100 has an inlet 110 and an outlet 120, with the inlet 110 connected to the filling mechanism. Material output from the filling mechanism enters the conveying pipe 100 through the inlet 110 and is then output into the casing through the outlet 120. Preferably, the conveying pipe 100 is a circular pipe.

[0058] The drive mechanism 200 drives the feed pipe 100 to rotate. Optionally, the drive mechanism 200 includes a drive unit 210 and a transmission mechanism 220, with the drive unit 210 connected to the feed pipe 100 via the transmission mechanism 220. Exemplarily, the drive unit 210 is a motor, and the transmission mechanism 220 includes a first pulley, a second pulley, and a transmission belt. The first pulley is connected to the output shaft of the motor, and the second pulley is connected to the first pulley via the transmission belt. The feed pipe 100 passes through and is connected to the second pulley. However, the transmission mechanism 220 in this invention is not limited to the above structure.

[0059] like Figure 1 and Figure 2As shown, the twisting mold 300 is disposed on the feed pipe 100 and located on the outer periphery of the output port 120. Specifically, the twisting mold 300 is mounted on the rotating arm 800, which has an extended position and a closed position. When the rotating arm 800 rotates to the extended position, the twisting mold 300 separates from the feed pipe 100, and the front end of the feed pipe 100 is exposed, so that the casing can be fitted onto the feed pipe 100 through the front end. When the rotating arm 800 rotates to the closed position, the twisting mold 300 is fitted onto the feed pipe 100.

[0060] like Figures 3 to 5 As shown, the clamping device 400 includes a cylindrical body 410 and a clamping member 420. The cylindrical body 410 is provided with a cavity 411 extending through its axial direction. The cylindrical body 410 is sleeved on the conveying pipe 100 through the cavity 411. The clamping member 420 is disposed in the cavity 411 and is coaxial with the cylindrical body 410. The clamping member 420 is provided with a first through hole 421 extending through its axial direction. The clamping member 420 is sleeved on the conveying pipe 100 through the first through hole 421, and a first annular gap 422 is formed between the first through hole 421 and the conveying pipe 100.

[0061] In use, one end of the casing opening 612 is fitted onto the feed pipe 100, and the knotted end of the casing is fitted onto the output port 120 of the feed pipe 100. Material is injected into the casing through the output port 120. The output port 120 of the output pipe cooperates with the twisting mold 300, allowing material to be injected into the casing located in front of the twisting mold 300, while preventing material from being injected into the casing located behind the twisting mold 300. The casing containing the injected material forms a sausage section, which extends between the two guide wheels 900 and protrudes forward.

[0062] In this process, after the sausage casing is inserted into the feed tube 100, the clamping device 400 is pushed, causing it to slide on the feed tube 100 until the sausage casing on the feed tube 100 passes through the first annular gap 422 and expands the clamping member 420, so that the sausage casing is clamped between the clamping member 420 and the feed tube 100. Preferably, the clamping member 420 is elastic and is made of an elastic polymer material, such as silicone. In this way, even if the shape of the sausage casing does not match the feed tube 100, clamping can still be achieved, thereby achieving a twist.

[0063] In some embodiments, such as Figures 3 to 5 As shown, the first through hole 421 is a first conical hole with a first opening 423 and a second opening 424. The diameter of the first opening 423 is larger than that of the second opening 424. A first annular gap 422 is formed between the second opening 424 and the conveying pipe 100. The casing passes through the first opening 423 and the second opening 424 in sequence and then through the first conical hole. The first conical hole guides the casing, allowing it to smoothly move into the first annular gap 422 and achieve a tight seal.

[0064] In some embodiments, such as Figures 3 to 5 As shown, in order to prevent the casing from springing back after the clamping member 420 clamps it, the clamping device 400 also includes a front fixing member 430, which is disposed in the cavity 411 and coaxial with the cylindrical body 410. The clamping member 420 is located behind the front fixing member 430, and the front fixing member 430 is provided with a second through hole 431 that penetrates its axial direction.

[0065] The second through hole 431 is a second conical hole with a third opening 432 and a fourth opening 433. The diameter of the third opening 432 is larger than that of the fourth opening 433. A second annular gap 434 is formed between the fourth opening 433 and the conveying pipe 100. The casing passes through the third opening 432 and the fourth opening 433 in sequence and then through the second conical hole. The second conical hole guides the casing to enter smoothly into the second annular gap 434.

[0066] When the sausage casing fitted on the conveying pipe 100 passes through the second annular gap 434, it opens the front fixing member 430 so that the sausage casing is tightly held between the front fixing member 430 and the conveying pipe 100.

[0067] In some embodiments, such as Figure 5 As shown, to match the shape of the first conical hole, the clamping member 420 has a conical outer surface 425, and the cavity 411 has a conical concave cavity 412. The clamping member 420 matches the conical concave cavity 412, thus constraining the clamping member 420 in the conical concave cavity 412.

[0068] In some embodiments, such as Figure 5 As shown, an annular groove 413 is provided on the inner wall of the cavity 411 along its circumference, and the edge of the front fixing member 430 is embedded in the annular groove 413. The annular groove 413 positions the front fixing member 430 and fixes it in the cavity 411.

[0069] In some embodiments, such as Figure 5 As shown, in order to connect the cavity 411 with the outside, the cylindrical body 410 is provided with a vent 414 that connects to the cavity 411.

[0070] In some embodiments, such as Figures 6 to 8 As shown, the twisting mechanism also includes a delivery pump 500, which is connected between the filling mechanism and the delivery pipe 100. The delivery pump 500 includes a stator 510, a rotor 520, and blades 530.

[0071] The stator 510 has an inner bore 511 and a first intake port 512 and a first exhaust port 513 communicating with the inner bore 511. The inner bore 511 has a bore wall 514. Optionally, the stator 510 is mounted in a housing 540. The housing 540 is used to house the stator 510, the rotor 520, and the blades 530. The housing 540 is provided with a second intake port 541 and a second exhaust port 542 communicating with the first intake port 512 and the first exhaust port 513, respectively.

[0072] The rotor 520 is eccentrically disposed in the inner hole 511 and configured to rotate about its rotation axis 550, which is specifically connected to the output shaft of the motor. The rotor 520 is provided with one or more mounting slots 521 arranged radially thereon, and the mounting slots 521 are rotationally symmetrical about the center of the rotor 520.

[0073] One or more blades 530 are slidably disposed in one or more mounting grooves 521. Each blade 530 has a first end 531 and a second end 532. The first end 531 and the second end 532 are respectively pressed against the hole wall 514 from both sides of the mounting groove 521.

[0074] The inner hole 511 is configured such that the total distance from the center of the rotor 520 to both sides of the hole wall 514 along the radial direction of the rotor 520 is the same as the length of the blade 530, so that the first end 531 and the second end 532 of the blade 530 can remain tightly abutting against the hole wall 514 during the rotation of the rotor 520. It should be noted that the term "same length" generally means equal length, but in order to allow the blade 530 to slide smoothly in the inner hole 511, the length of the blade 530 is slightly less than the total distance from the center of the rotor 520 to both sides of the hole wall 514 along the radial direction of the rotor 520.

[0075] The pump 500 relies on the force exerted by the bore wall 514 on the blades 530 to drive the blades 530 to slide within the mounting groove 521. When the first end 531 of the blade 530 is compressed back into the mounting groove 521 by one side of the bore wall 514, the second end 532 extends out of the mounting groove 521 to abut against the other side of the bore wall 514. Conversely, when the second end 532 of the blade 530 is compressed back into the mounting groove 521 by one side of the bore wall 514, the first end 531 extends out of the mounting groove 521 to abut against the other side of the bore wall 514. Even when the rotor 520 rotates at low speed and cannot generate sufficient centrifugal force, both the first end 531 and the second end 532 remain firmly abutted against the bore wall 514. Furthermore, even if material gets stuck in the slit, the force exerted by the bore wall 514 on the blades 530 prevents them from getting stuck, thus improving the operational stability of the mounting groove 521.

[0076] In some embodiments, such as Figures 6 to 8As shown, the hole wall 514 includes a first curved wall surface 5141, a first arc wall surface 5142, a second curved wall surface 5143, and a second arc wall surface 5144 connected in sequence; the second arc wall surface 5144 is eccentrically arranged relative to the first arc wall surface 5142, and the radius of the second arc wall surface 5144 is smaller than the radius of the first arc wall surface 5142; the second arc wall surface 5144 is concentrically arranged with the rotor 520; the side surface of the rotor 520 is separated from the first curved wall surface 5141, the first arc wall surface 5142, and the second curved wall surface 5143 to form a feeding area 515, a storage area 516, and a discharge area 517, respectively, and the side surface of the rotor 520 is also in close contact with the second arc wall surface 5144 to form a compression area 518.

[0077] When the rotor 520 rotates, a series of sealed working cavities are formed between the two blades 530, the stator 510 and the rotor 520. In the feeding zone 515, the first end 531 or the second end 532 of the blade 530 extends outward, and the volume of the sealed working cavity gradually increases, creating a vacuum, so that the material is drawn in through the first suction port 512.

[0078] In the discharge zone 517, the first end 531 or the second end 532 of the blade 530 retracts inward, the volume of the sealed cavity gradually decreases, and the material in the sealed working cavity is pressed out and output.

[0079] In the storage area 516, the first end 531 or the second end 532 of the blade 530 extends outward to its maximum length and maintains the extension length unchanged. At this time, the volume of the sealed working cavity gradually increases to its maximum.

[0080] In the compression zone 518, the first end 531 or the second end 532 of the blade 530 retracts inward until it is fully retracted and remains fully retracted, at which point the volume of the sealed working chamber gradually shrinks to its minimum.

[0081] In some embodiments, the blade 530 further includes a connecting portion 533, with a first end portion 531 and a second end portion 532 connected to both ends of the connecting portion 533. The width of the connecting portion 533 is smaller than the width of the first end portion 531 and the second end portion 532, forming a notch 534 between the first end portion 531 and the second end portion 532. The two blades 530 intersect, and the connecting portion 533 of one blade 530 is embedded in the notch 534 of the other blade 530. The notch 534 of one blade 530 provides a clearance function for the other blade 530, meaning the two blades 530 do not interfere with each other and can slide freely.

[0082] In another embodiment of the invention, such as Figure 9As shown, an enema twisting device is also provided, including a filling mechanism and a twisting mechanism, with the filling mechanism connected to the twisting mechanism. The specific structure of the twisting mechanism is as described in the above embodiments. Since this enema twisting device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0083] In some embodiments, such as Figures 9 to 11 As shown, the filling mechanism includes a container 600 and a hydraulic mechanism 700. The hydraulic mechanism 700 includes a hydraulic actuator 710 and a pump piston 720. The hydraulic actuator 720 drives the pump piston 710.

[0084] like Figures 12 to 15 As shown, container 600 includes a tank body 610, a cover 620, and connecting bolts 630. A cavity 611 is formed inside the tank body 610. A pump plug 720 is disposed within the cavity 611 and fits against the wall of the cavity 611. The cavity 611 has an opening 612. The tank body 610 has a discharge section 613 communicating with the cavity 611, and the discharge section 613 is connected to a twisting mechanism. Specifically, the discharge section 613 is a discharge pipe, which is connected to the conveying pump 500 of the twisting mechanism to convey materials to the conveying pipe 100 via the conveying pump 500.

[0085] An upwardly extending fastener 640 is provided on the outer side of the opening 612 on the can body 610, and the fastener 640 has a fastening notch 641. The cover 620 is sealed on the opening 612, and a pad 650 is provided on the periphery of the top surface of the cover 620. A limiting member 660 is provided on the cover 620 on one side of the pad 650.

[0086] A connecting bolt 630 passes through the cover 620 and is screwed to the can body 610. The connecting bolt 630 and the pad 650 are located at opposite ends of the cover 620. The cover 620 is fastened to the can body 610 by the connecting bolt 630, and the cover 620 rotates around the connecting bolt 630 to open or close the cover opening 612. When the cover 620 is in the position of closing the cover opening 612, the limiting member 660 abuts against the fastener 640, and the pad 650 is inserted into the fastening notch 641 so that the fastener 640 fastens the cover 620.

[0087] Compared to existing filling mechanisms that use a lifting method to open the cap 620, this filling container uses a rotation method to open or seal the opening 612 of the can body 610. For example, an operating handle 621 is provided on the cap 620 to open or close the cap. In this embodiment, viewed from a top angle, the opening direction of the cap 620 is clockwise. Conversely, the cap 620 rotates counterclockwise until the opening 612 is sealed. It should be understood that in another embodiment of the present invention, the opening direction of the cap 620 can also be counterclockwise.

[0088] Combination Figures 12 to 15 The working principle of this invention is explained in detail below: When opening the cover 620, loosen the connecting bolt 630. The end of the cover 620 connected to the connecting bolt 630 tilts upward, and the end of the cover 620 with the pad 650 is pressed down, allowing the pad 650 to disengage from the fastening notch 641. Then, rotate the cover 620 clockwise to open it. When sealing the opening 612, keep the connecting bolt 630 loose and rotate the cover 620 until the limiting member 660 abuts against the fastener 640, and the pad 650 is inserted into the fastening notch 641. At this time, the cover 620 stops rotating and seals the top of the opening 612. Then, tighten the connecting bolt 630 to securely connect the cover 620 and the can body 610. At the same time, the fastener 640 fastens the pad 650, thus securing the cover 620 to the can body 610. The cap 620 of the filling mechanism is opened by rotation, and the two ends of the cap 620 are fastened by connecting bolts 630 and pads 650. It features simple operation and a robust structure.

[0089] In some embodiments, the top surface of the pad 650 is provided with an inclined surface 651 and a first plane 652, the first plane 652 being connected to the top side of the inclined surface 651, the top side of the inclined surface 651 being located on the side of the inclined surface 651 near the limiting member 660. The top surface of the fastening notch 641 is provided with a second plane 642, and when the cover 620 is located in the position of sealing the opening 612, the second plane 642 is in close contact with the first plane 652.

[0090] When the cap opening 612 is closed, the pad 650 contacts the fastener 640 before the limiting member 660. That is, the bottom side of the inclined surface 651 is first inserted into the fastening notch 641. As the cap 620 rotates, the height of the contact position between the inclined surface 651 and the fastener 640 gradually increases. That is, the fastener 640, through the pad 650, gradually presses the cap 620 towards the can body 610. Finally, when the first plane 652 contacts the fastener 640, the degree to which the fastener 640, through the pad 650, presses the cap 620 towards the can body 610 reaches its maximum, so as to achieve gradual tightening.

[0091] In some embodiments, such as Figure 12 , Figure 14 and Figure 15 As shown, the lid 620 has a first protrusion 622 on its edge, and the can body 610 has a second protrusion 614. The first protrusion 622 and the second protrusion 614 fit together, and a connecting bolt 630 passes through the first protrusion 622 and is screwed to the second protrusion 614. The first protrusion 622 and the second protrusion 614 can prevent changes to the shape of the lid 620 and the can body 610. Generally, the cross-section of the cavity 611 of the can body 610 needs to remain circular. The first protrusion 622 and the second protrusion 614 support each other and stably support the lid 620 when it is open.

[0092] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
