Description

Technical Field

[0001] This utility model relates to the field of sausage filling technology, specifically to a sausage filling device. Background Technology

[0002] Sausage stuffing machines are key pieces of equipment in meat processing, used to stuff minced meat into casings to make sausages. CN222692647U discloses a sausage stuffing machine that includes a cleaning mechanism consisting of scrapers, guide strips, and other components mounted on a rotating shaft inside the hopper. This mechanism can simultaneously scrape off the minced meat adhering to the inner wall of the hopper during the mixing process and guide it back to the mixing area, thus solving the problem of waste caused by raw material residue adhering to the inner wall of the hopper.

[0003] Existing sausage filling equipment has the following problems: the movement of the casing mainly depends on the thrust of the meat filling squeezed out of the filling tube and the passive traction of subsequent processes. In the actual filling process, the casing is prone to axial displacement, which leads to uneven thickness and irregular shape of the filled sausages. The speed of casing movement is difficult to keep in stable match with the filling speed: if the movement is too slow, the casing is prone to bursting; if the movement is too fast, it is prone to incomplete filling, air bubbles, or leakage of meat filling at the tube opening.

[0004] Based on the above situation, there is an urgent need for a sausage filling device to solve the problem that the speed of sausage casing movement is difficult to match with the speed of meat filling. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing sausage filling equipment relies mainly on the pushing force of the meat filling being squeezed out of the filling tube and the passive traction of subsequent processes for the movement of the casing. In actual filling, the casing is prone to axial displacement, resulting in sausages of uneven thickness and irregular shape. The speed of casing movement is difficult to match with the filling speed: too slow movement can cause the casing to burst; too fast movement can lead to incomplete filling, air bubbles, or leakage of meat filling at the tube opening. This invention solves the problem of the casing movement speed being difficult to match with the filling speed.

[0006] The technical solution of this utility model is as follows: An enema device, comprising: An enema mechanism, wherein the outlet of the enema mechanism is equipped with an enema pipe for discharging materials; The sausage casing traction mechanism includes at least two traction rollers disposed on the side of the enema tube, and a traction motor for driving the traction rollers to rotate; A clamping mechanism is connected to the traction roller and is used to drive the traction roller to press against or move away from the enema tube; The control unit is electrically connected to the traction motor and is used to control the linear speed of the traction roller to match the enema speed of the enema mechanism.

[0007] In existing sausage filling equipment, the movement of the casing mainly relies on the thrust of the meat filling squeezed out of the filling tube and the passive traction of subsequent processes. In actual filling, the casing is prone to axial displacement, resulting in sausages of uneven thickness and irregular shape. The speed of casing movement is difficult to keep in stable match with the filling speed: too slow movement can cause the casing to burst; too fast movement can lead to incomplete filling, air bubbles, or leakage of meat filling at the tube opening. In this solution, the speed of the traction motor is adjusted by the control unit, thereby matching the linear speed of the traction roller with the filling speed of the sausage filling mechanism. The traction roller drives the casing to move, effectively avoiding problems such as uneven filling, casing bursting, or leakage caused by casing displacement. This improves the stability and consistency of filling quality and solves the problem of the casing movement speed being difficult to match with the filling speed.

[0008] Furthermore, this solution is not limited to the specific structure of the pressing mechanism. One feasible solution is that the pressing mechanism includes a movable shaft seat connected to the traction roller, the movable shaft seat is connected to a linear drive member, and the linear drive member is mounted on the enema mechanism. When this solution is adopted, the linear drive member drives the traction roller to contact and press against the enema tube to facilitate the traction of the casing; the linear drive member drives the traction roller away from the enema tube to facilitate the replacement of the casing.

[0009] Furthermore, this solution does not exclusively limit the specific structure of the linear drive component. One feasible solution is that the linear drive component is a cylinder, an electric push rod, or a hydraulic cylinder. Using these standardized and mature linear drive components ensures that the clamping mechanism operates quickly, powerfully, and controllably. They can all provide stable and adjustable driving force, respond rapidly, and are easy to integrate with the electrical control system of the equipment to achieve automated control, making the entire clamping and separation process more reliable and efficient.

[0010] Furthermore, to facilitate the synchronous rotation of all the traction rollers, one feasible solution is to install friction wheels on the shaft of each traction roller, with friction wheel transmission between adjacent traction rollers. With this solution, the friction wheels can automatically adapt to the distance changes caused by the swinging or moving of adjacent traction rollers. Compared to gear or synchronous belt transmissions that require a fixed center distance, the structure is simpler and more reliable, avoiding jamming or wear problems caused by mechanical interference, achieving synchronous rotation of all the traction rollers, and improving the durability and fault tolerance of the mechanism.

[0011] Furthermore, to avoid scratching the casing during traction, one feasible solution is to cover the traction roller with an elastic layer. When this solution is adopted, the elastic layer can effectively protect the casing from being scratched due to its buffering effect, and also increases the static friction between the surface of the traction roller and the casing, preventing slippage.

[0012] Furthermore, this solution does not exclusively limit the specific structure of the enema mechanism. One feasible solution is as follows: the enema mechanism includes a feeding cylinder and a bracket for supporting the feeding cylinder. A screw is installed inside the feeding cylinder and the screw is connected to an enema motor. The enema motor is electrically connected to a control unit. When this solution is adopted, the enema motor drives the screw to rotate at a uniform speed, thereby keeping the filling speed stable and further improving the stability and consistency of the filling quality.

[0013] Compared with existing technologies, the beneficial effects of this utility model are: 1. By adjusting the rotation speed of the traction motor through the control unit, the linear speed of the traction roller is matched with the filling speed of the sausage filling mechanism. The traction roller drives the sausage casing to move, which effectively avoids problems such as uneven filling, casing rupture or leakage due to casing deviation, improves the stability and consistency of filling quality, and solves the problem that the casing moving speed is difficult to match with the meat filling speed. 2. Since the pressing mechanism includes a movable shaft seat connected to the traction roller, the movable shaft seat is connected to a linear drive component and the linear drive component is mounted on the enema mechanism, the linear drive component drives the traction roller to contact and press against the enema tube, so as to pull the casing; the linear drive component drives the traction roller away from the enema tube, so as to replace the casing. Third, since friction wheels are installed on the shaft of the traction roller and the transmission between two adjacent traction rollers is a friction wheel transmission, the friction wheels can automatically adapt to the distance changes caused by the swinging or moving of the two adjacent traction rollers. Compared with gear or synchronous belt transmission that requires a fixed center distance, the structure is simpler and more reliable, avoiding jamming or wear problems caused by mechanical interference, realizing the synchronous rotation of all the traction rollers, and improving the durability and fault tolerance of the mechanism.

Furthermore, the term "comprising" or any other variations thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0017] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0018] Example: Please refer to Figure 1 , Figure 2 and Figure 4 An enema device, comprising: Enema mechanism 1, the outlet of enema mechanism 1 is equipped with an enema pipe 11 for discharging materials; The sausage casing traction mechanism 2 includes at least two traction rollers 21 disposed on the side of the enema tube 11, and a traction motor 22 for driving the traction rollers 21 to rotate. The clamping mechanism 3 is connected to the traction roller 21 and is used to drive the traction roller 21 to press against or move away from the enema tube 11; The control unit is electrically connected to the traction motor 22 and is used to control the linear speed of the traction roller 21 to match the enema speed of the enema mechanism 1.

[0019] In existing sausage filling equipment, the movement of the casing mainly relies on the thrust of the meat filling squeezed out of the filling tube and the passive traction of subsequent processes. In the actual filling process, the casing is prone to axial displacement, which leads to uneven thickness and irregular shape of the filled sausages. It is also difficult to keep the speed of casing movement stable and matched with the filling speed of the meat filling: if the movement is too slow, the casing may be torn; if the movement is too fast, it may lead to incomplete filling, air bubbles, or leakage of meat filling at the tube opening. In this solution, the speed of the traction motor 22 is adjusted by the control unit, so that the linear speed of the traction roller 21 is matched with the filling speed of the sausage filling mechanism 1. The traction roller 21 drives the casing to move, which effectively avoids problems such as uneven filling, casing tearing, or leakage caused by casing displacement, improves the stability and consistency of filling quality, and solves the problem that the casing movement speed is difficult to match with the filling speed of the meat filling.

[0020] Optionally, the control unit includes a frequency converter and is electrically connected to the traction motor 22, which allows for convenient and quick adjustment of the speed of the traction motor 22.

[0021] Reference Figure 2 and Figure 4 This solution does not limit the specific structure of the pressing mechanism 3. One feasible solution is: the pressing mechanism 3 includes a movable shaft seat 31 connected to the traction roller 21. The movable shaft seat 31 is connected to a linear drive 32, and the linear drive 32 is mounted on the enema mechanism 1. When this solution is adopted, the linear drive 32 drives the traction roller 21 to contact and press against the enema tube 11 to facilitate the traction of the casing; the linear drive 32 drives the traction roller 21 away from the enema tube 11 to facilitate the replacement of the casing.

[0022] This solution does not limit the specific structure of the linear drive component 32. One feasible solution is that the linear drive component 32 is a cylinder, an electric push rod, or a hydraulic cylinder. Using these standardized and mature linear drive components ensures that the clamping mechanism operates quickly, powerfully, and controllably. They can all provide stable and adjustable driving force, respond quickly, and are easy to integrate with the electrical control system of the equipment to achieve automated control, making the entire clamping and separation process more reliable and efficient.

[0023] Reference Figure 4 To facilitate the synchronous rotation of all traction rollers 21, one feasible solution is to install friction wheels 23 on the shaft of the traction rollers 21 and to use friction wheel transmission between adjacent traction rollers 21. With this solution, the friction wheels 23 can automatically adapt to the distance changes caused by the swinging or moving of adjacent traction rollers 21. Compared with gear or synchronous belt transmission that requires a fixed center distance, the structure is simpler and more reliable, avoiding jamming or wear problems caused by mechanical interference, realizing the synchronous rotation of all traction rollers 21, and improving the durability and fault tolerance of the mechanism.

[0024] To avoid scratching the casing during traction, one feasible solution is to cover the traction roller 21 with an elastic layer. Specifically, the elastic layer can be a food-grade silicone layer, rubber layer, or polyurethane layer. When this solution is adopted, the cushioning effect of the elastic layer can effectively protect the casing from being scratched, and also increase the static friction between the surface of the traction roller 21 and the casing, preventing slippage.

[0025] Reference Figure 2 and Figure 5 This solution does not limit the specific structure of the enema mechanism 1. One feasible solution is as follows: the enema mechanism 1 includes a feeding cylinder 12 and a bracket 13 for supporting the feeding cylinder. The feeding cylinder 12 has an inlet 121. A screw 14 is installed inside the feeding cylinder 12 and the screw 14 is connected to an enema motor 15. The enema motor 15 is electrically connected to the control unit. When this solution is adopted, the screw 14 is driven to rotate at a uniform speed by the enema motor 15, thereby keeping the filling speed stable and further improving the stability and consistency of the filling quality.

[0026] Reference Figure 2 and Figure 3 Optionally, a gearbox 16 is installed between the enema motor 15 and the screw 14. With this option, the filling speed can be easily and quickly adjusted by adjusting the gearbox 16.

[0027] Optionally, the control unit is a PLC or a microcontroller controller, which receives the speed signal from the encoder of the enema motor 15 as enema speed feedback, calculates and outputs the control signal to the frequency converter of the traction motor 22 through the built-in PID algorithm, and then dynamically adjusts the speed of the traction motor 22 so that the linear speed of the traction roller 21 matches the enema speed.

[0028] Preferably, the movable shaft seat 31 is connected to two guide rods 33, and both guide rods 33 are slidably connected to the bracket 13. With this solution, the movable shaft seat 31 can move more smoothly under the guidance of the guide rods 33.

[0029] The working principle of this embodiment: Before filling begins, the operator places the sausage casing onto the filling tube 11. The control unit controls the linear drive component, which in turn drives the movable shaft seat 31 and the traction roller 21 mounted on it to move towards the filling tube 11 and press the sausage casing. After startup, the filling motor 15 drives the screw 14 to rotate at a uniform speed, extruding the meat filling in the feeding cylinder 12 from the filling tube 11 at a stable filling speed. The control unit synchronously controls the speed of the traction motor 22 according to the set filling speed, so that the linear speed of the traction roller 21 matches the filling speed. The active traction roller 21, through the friction between its elastic layer and the sausage casing, drives the sausage casing to move uniformly and stably along the axial direction of the filling tube. It also drives the driven traction roller 21 to rotate synchronously through the friction wheel transmission, together completing the traction of the sausage casing. After filling is completed, the linear drive component 32 drives the traction roller 21 away from the filling tube 11, making it easy to replace the next section of sausage casing.

[0030] To address the issue of matching the casing movement speed with the meat filling speed, this solution adjusts the rotational speed of the traction motor 22 via a control unit. This allows the linear speed of the traction roller 21 to match the filling speed of the sausage filling mechanism 1. The traction roller 21 then drives the casing to move, effectively preventing problems such as uneven filling, casing rupture, or leakage due to casing misalignment. This improves the stability and consistency of the filling quality and solves the problem of matching the casing movement speed with the meat filling speed.

[0031] To facilitate casing replacement, in this design, the clamping mechanism 3 includes a movable shaft seat 31 connected to the traction roller 21. The movable shaft seat 31 is connected to a linear drive 32, which is mounted on the enema mechanism 1. The linear drive 32 drives the traction roller 21 to contact and press against the enema tube 11, thus facilitating casing traction. The linear drive 32 also drives the traction roller 21 away from the enema tube 11, thus facilitating casing replacement.

[0032] To enable all traction rollers 21 to rotate synchronously, in this design, friction wheels 23 are installed on the shaft of the traction rollers 21, and friction wheel transmission is used between two adjacent traction rollers 21. The friction wheels 23 can automatically adapt to the distance changes caused by the swinging or moving of the two adjacent traction rollers 21. Compared with gear or synchronous belt transmission that requires a fixed center distance, the structure is simpler and more reliable, avoiding jamming or wear problems caused by mechanical interference, realizing synchronous rotation of all traction rollers 21, and improving the durability and fault tolerance of the mechanism.
