Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to an automatic enema machine, particularly a quantitative mechanism for the automatic enema machine, and a method for using the automatic enema machine. Background Technology

[0002] Sausage is a way of preserving meat. The meat is cut into pieces or minced, seasoned and mixed evenly, and then stuffed into casings. Depending on the required length, the casings are twisted or divided into sections with string to form a cylindrical, tubular food.

[0003] Existing enema equipment, such as the enema and ligation integrated machine (CN 119111604A) disclosed in the Chinese Patent Database, includes: a housing with a groove, in which a vacuum vane metering pump is disposed, and a feeding unit located on the housing directly above the vacuum vane metering pump; a conveying unit disposed on the housing and cooperating with the vacuum vane metering pump, and including a conveying pipe; a twisting ligator disposed on one side of the housing and connected to the conveying pipe, and a thread guide rotatably connected to one side of the twisting ligator; a clamping nozzle segmenter disposed on one side of the twisting nozzle segmenter, and the clamping nozzle segmenter includes a housing and clamping nozzles symmetrically disposed on one side of the housing, the two clamping nozzles forming a shrinkage hole, and the thread on the thread guide passing through the shrinkage hole; the vacuum vane metering pump includes a cam and a rotating wheel rotatably connected in the groove, and the rotating wheel has blades arranged in a circumferential array that fit against the cam.

[0004] The aforementioned integrated machine uses a vacuum vane metering pump to achieve quantitative conveying of meat. However, the operation of this metering pump not only relies on external power equipment, but also the grooves and cams are matched through complex curves, resulting in a relatively complex structure of the entire metering pump, which affects the design and assembly. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a simple automatic enema machine quantitative mechanism and a method for using the quantitative mechanism.

[0006] This invention provides a quantitative mechanism for an automatic sausage enema machine, comprising a quantitative box with an internal cavity, an inlet and a outlet on the front and rear sides of the quantitative box, respectively. The cavity is racetrack-shaped, and its inner wall includes two symmetrically arranged arc surfaces. Two rotating shafts are vertically rotatable within the cavity, with their central axes collinear with the central axes of the two arc surfaces. A material passage is formed between the two rotating shafts, and the inlet and outlet are both directly opposite the material passage. The outer walls of both rotating shafts are fixed with... There is a ring of blades evenly spaced along the circumference of the corresponding rotating shaft. The blades are flat and vertically arranged. The lower ends of both rotating shafts extend out of the cavity. Gears are also fitted and fixed on both rotating shafts and mesh with each other. A circular grating disk is fitted and fixed on one of the rotating shafts. The outer edge of the grating disk has a vertical through groove. A slotted photoelectric switch is fixed on the bottom wall of the metering box. The outer edge of the grating disk is inserted into the detection groove of the slotted photoelectric switch. The slotted photoelectric switch is electrically connected to the controller.

[0007] During use, the meat is fed in through the inlet and pushed backward, eventually being discharged through the outlet. As the meat flows, it comes into contact with the blades and pushes them to rotate. At the same time, the two shafts rotate synchronously under the meshing of two gears. The grating disk rotates with the corresponding shaft. A pulse signal is generated after the meat enters the detection groove of the slotted photoelectric switch in each channel. The controller, which is electrically connected to the slotted photoelectric switch, counts the pulse signals. When the count value reaches the set value, the meat stops being pushed, and the quantitative output of meat is achieved.

[0008] In this application, the rotating shaft contacts the meat with blades and is rotated entirely by the meat, thus eliminating the need for an additional power source. At the same time, it uses a grating disk and a slotted photoelectric switch to count pulses to achieve quantitative output of meat. The structure is significantly simpler and has the advantages of low design difficulty and low cost.

[0009] In the aforementioned automatic sausage filling machine's quantitative mechanism, each rotating shaft has four blades. As the shafts rotate, the blades on both shafts alternately enter the material passage. This design achieves rapid quantitative discharge with a relatively small number of blades. This not only effectively shortens the distance between the two rotating shafts, making the entire quantitative mechanism more compact and reducing space occupation, but also significantly improves discharge efficiency.

[0010] In the above-mentioned automatic enema machine's quantitative mechanism, the length of the blade in the radial direction of the rotating shaft is slightly less than the distance between the two rotating shafts, in order to further shorten the distance between the two rotating shafts.

[0011] In the aforementioned automatic enema machine's quantitative mechanism, the length of the blade in the radial direction of the rotating shaft is slightly smaller than the radius of the arc surface.

[0012] In the above-mentioned automatic enema machine's quantitative mechanism, the length of the blade along the axis of rotation is slightly less than the cavity depth.

[0013] The blades are designed with the above dimensions to ensure full contact between the blades and the meat, thereby improving discharge efficiency and accuracy.

[0014] In the above-mentioned automatic enema machine's quantitative mechanism, the upper end of the rotating shaft extends out of the cavity, and both the upper and lower ends of the rotating shaft are rotatably engaged with the quantitative box through bearings; the top and bottom of the middle part of the rotating shaft are sealed with the inner wall of the quantitative box through sealing rings.

[0015] In the above-mentioned automatic enema machine quantitative mechanism, the grating disk includes a central tube sleeved on the corresponding rotating shaft and an annular body formed on the outer wall of the central tube, and the aforementioned through groove is formed on the outer edge of the annular body; the central tube is circumferentially engaged with the corresponding rotating shaft by a flat key, and the central tube is clamped and positioned between the corresponding gear and the inner ring of the corresponding bearing, so that the positioning of the grating disk does not require additional fasteners, thereby further simplifying the structure.

[0016] The present invention provides an automatic sausage filling machine quantitative mechanism, including a mixing device and a sausage filling device, characterized in that the automatic sausage filling machine quantitative mechanism is provided between the mixing device and the sausage filling device, and the inlet and outlet of the automatic sausage filling machine quantitative mechanism are respectively connected to the outlet of the mixing device and the inlet of the sausage filling device through pipelines.

[0017] The present invention provides a method for using an automatic enema machine, characterized by comprising the following steps: Step 1: Run the automatic sausage stuffer to obtain the first sausage section; Step 2: Obtain the weight of the first sausage segment mentioned above, and record it as the calibration weight; Step 3: Obtain the number of pulse signals received by the controller during the first stage of sausage production, and record it as the calibration weight pulse count; Step 4: Based on the actual required sausage weight, calculate the number of pulse signals received by the controller when producing that weight. This number of pulse signals is recorded as the required weight pulse count, which is calculated using the following formula: Required weight pulse count = Required weight × Calibration weight pulse count / Calibration weight; Step 5: Input the calculated required weight pulse count into the controller and restart the automatic sausage filling machine to begin production.

[0018] Compared with the prior art, the present invention has the following advantages: 1. In this application, the rotating shaft contacts the meat with the blades and is rotated entirely by the meat, thus eliminating the need for an additional power source. At the same time, it uses a grating disk and a slotted photoelectric switch to count pulses to achieve quantitative output of meat. The structure is significantly simpler and has the advantages of low design difficulty and low cost.

[0019] 2. The above design can achieve rapid quantitative discharge with a smaller number of blades. This not only effectively shortens the distance between the two rotating shafts, making the structure of the entire quantitative mechanism more compact and reducing space occupation, but also improves discharge efficiency.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] Example 1: As Figure 1 As shown, the automatic sausage filling machine includes a mixing device 1, a sausage filling device 2, and an automatic sausage filling metering mechanism disposed between the mixing device 1 and the sausage filling device 2. The mixing device 1 and the sausage filling device 2 are the same as the sausage filling machines sold on the market and are both existing technologies. Their specific structures will not be described in detail here.

[0028] The automatic sausage filling machine's quantitative mechanism includes a quantitative box 3 with an internal cavity. The quantitative box 3 has an inlet 3a and a discharge port 3b on its front and rear sides, respectively. The inlet 3a and the discharge port 3b are connected to the outlet of the mixing device 1 and the inlet of the sausage filling device 2 through pipes 4, respectively.

[0029] Specifically like Figure 2 and Figure 4As shown, the metering box 3 includes a box body 3c and a box cover 3d disposed on the top of the box body 3c, with the box body 3c and the box cover 3d forming the aforementioned cavity. The inlet 3a and the outlet 3b are both located on the side wall of the box body 3c. The box cover 3d is detachably fixed to the box body 3c by a ring of screws. An annular groove coaxial with the box body 3c is formed on the top wall of the box body 3c, with the ring of screws located outside the annular groove. An annular sealing gasket is provided within the annular groove, and the two ends of the annular sealing gasket contact and seal with the inner side of the top wall of the box cover 3d and the bottom wall of the annular groove, respectively, to form a stable seal between the box body 3c and the box cover 3d.

[0030] like Figures 2 to 5 As shown, the cavity is racetrack-shaped, and preferably the entire metering box 3 is racetrack-shaped. The inner wall of the cavity is formed by two arc surfaces 3e and two vertical planes 3f. The axes of the arc surfaces 3e extend vertically, and the two arc surfaces 3e are symmetrically arranged. Two rotating shafts 5 are vertically rotatable within the cavity, and the central axes of the two rotating shafts 5 are collinear with the central axes of the two arc surfaces 3e. The feed inlet 3a and discharge outlet 3b are respectively located on the two vertical planes 3f, forming a material passage between the two rotating shafts 5. Both the feed inlet 3a and discharge outlet 3b are directly opposite the material passage. A ring of evenly spaced blades 5a, flat and vertically arranged, is fixed to the outer wall of each rotating shaft 5. Both rotating shafts 5 have their lower ends extending into cavities. Gears 6 are fitted and fixed on both rotating shafts 5, and the two gears 6 mesh with each other. One of the rotating shafts 5 also has a circular grating disk 7 fitted and fixed on it. The outer edge of the grating disk 7 has a vertical through-groove 7a, and the through-groove 7a is evenly distributed around the circumference of the grating disk 7. A slotted photoelectric switch 8 is fixed on the bottom wall of the metering box 3, and the outer edge of the grating disk 7 is inserted into the detection groove 8a of the slotted photoelectric switch 8. The slotted photoelectric switch 8 is electrically connected to the controller.

[0031] Among them, the slotted photoelectric switch 8 is an existing product that can be purchased directly on the market, and the communication between the slotted photoelectric switch 8 and the controller is also a very conventional technology.

[0032] During use, the meat is fed into the inlet 3a and pushed backward, eventually being discharged through the outlet. During the flow, the meat comes into contact with the blades 5a and pushes the blades 5a to rotate. At the same time, the two rotating shafts 5 rotate synchronously under the meshing of the two gears 6. The grating disk 7 rotates with the corresponding rotating shaft 5. When the meat enters the detection groove 8a of the slotted photoelectric switch 8 in each through slot 7a, a pulse signal is generated. The controller, which is electrically connected to the slotted photoelectric switch 8, counts the pulse signals. When the count value reaches the set value, the meat stops being pushed, and at this time, the quantitative output of meat is achieved.

[0033] In this application, the rotating shaft 5 contacts the meat material with the blade 5a and is rotated entirely by the meat material, thus eliminating the need for an additional power source. At the same time, it uses the grating disk 7 and the slotted photoelectric switch 8 to count pulses to achieve quantitative output of meat material. The structure is significantly simpler and has the advantages of low design difficulty and low cost.

[0034] In this embodiment, The rotating shaft 5 and the blade 5a are an integral structure.

[0035] like Figure 4 As shown, each rotating shaft 5 has four blades 5a, meaning that adjacent blades 5a are arranged at 90 degrees on the same rotating shaft 5. As the rotating shaft 5 rotates, the blades 5a on the two rotating shafts 5 alternately enter the material passage. This design achieves rapid quantitative material discharge with a relatively small number of blades 5a. This not only effectively shortens the distance between the two rotating shafts 5, making the entire quantitative mechanism more compact and reducing space occupation, but also significantly improves discharge efficiency.

[0036] Preferably, the radial length of blade 5a on the rotating shaft 5 is slightly less than the distance between the two rotating shafts 5, to further shorten the distance between the two rotating shafts 5. The radial length of blade 5a on the rotating shaft 5 is slightly less than the radius of the arc surface 3e. The axial length of blade 5a on the rotating shaft 5 is slightly less than the cavity depth. With the above-mentioned dimensional design, blade 5a can fully contact the meat, improving discharge efficiency and accuracy.

[0037] like Figure 5 As shown, the rotating shaft 5 is installed as follows: the upper end of the rotating shaft 5 extends out of the cavity, and both the upper and lower ends of the rotating shaft 5 are rotatably engaged with the metering box 3 via bearings 9; the top and bottom of the middle part of the rotating shaft 5 are sealed to the inner wall of the metering box 3 via sealing rings 10. Specifically, the outer diameter of the middle part of the rotating shaft 5 is larger than the outer diameter of the end of the rotating shaft 5. Two stepped grooves 3g are provided on the top and bottom walls of the metering box 3. The vertical cross-section of the stepped grooves 3g is L-shaped, and the four stepped grooves 3g are respectively set opposite to the two ends of the two rotating shafts 5. Both ends of the rotating shaft 5 extend into the corresponding stepped grooves 3g. Each stepped groove 3g is provided with the aforementioned bearing 9. The bearing 9 is a ball bearing 9, which includes an inner ring and an outer ring. The outer ring of the bearing 9 is fixedly connected to the side wall of the corresponding stepped groove 3g, and the inner ring of the bearing 9 is fixedly connected to the corresponding rotating shaft 5. Annular grooves 2 are provided on the top and bottom walls of the middle part of the rotating shaft 5. The sealing rings 10 mentioned above are provided in the annular grooves 2. The two ends of the sealing rings 10 on the upper side are in contact with the inner side of the top wall of the metering box 3 and the bottom wall of the corresponding annular groove 2, respectively, and the two ends of the sealing rings 10 on the lower side are in contact with the inner side of the bottom wall of the metering box 3 and the bottom wall of the corresponding annular groove 2, respectively.

[0038] like Figure 3 and Figure 5As shown, the grating disk 7 is installed as follows: The grating disk 7 includes a central tube 7b fitted onto the corresponding rotating shaft 5 and an annular body formed on the outer wall of the central tube 7b, and the annular body and the central tube 7b are an integral structure. A through groove 7a is formed on the outer edge of the annular body; the central tube 7b is circumferentially engaged with the corresponding rotating shaft 5 via a flat key, and the central tube 7b is clamped and positioned between the inner ring of the corresponding gear 6 and the inner ring of the corresponding bearing 9. That is, at this time, the two end faces of the central tube 7b are respectively pressed against the inner ring of the corresponding gear 6 and the inner ring of the corresponding bearing 9, so that the positioning of the grating disk 7 does not require additional fasteners, further simplifying the structure.

[0039] In this embodiment, the method of using the automatic enema machine includes the following steps: Step 1: Run the automatic sausage stuffer to obtain the first sausage section; Step 2: Obtain the weight of the first sausage segment mentioned above, and record it as the calibration weight; Step 3: Obtain the number of pulse signals received by the controller during the first stage of sausage production, and record it as the calibration weight pulse count; Step 4: Based on the actual required sausage weight, calculate the number of pulse signals received by the controller when producing that weight. This number of pulse signals is recorded as the required weight pulse count, which is calculated using the following formula: Required weight pulse count = Required weight × Calibration weight pulse count / Calibration weight; Step 5: Input the calculated required weight pulse count into the controller and restart the automatic sausage filling machine to begin production.

[0040] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1, except that the method of using the automatic sausage enema machine includes the following steps: Step 1: Run the automatic sausage stuffer to obtain the first sausage section; Step 2: Obtain the length of the first sausage segment mentioned above, and record it as the calibration length; Step 3: Obtain the number of pulse signals received by the controller during the first stage of sausage production, and record it as the calibration length pulse count; Step 4: Based on the actual required sausage length, calculate the number of pulse signals received by the controller when producing that length. This number of pulse signals is recorded as the required length pulse count, which is calculated using the following formula: Required length pulse count = Required length × Calibration length pulse count / Calibration length; Step 5: Input the calculated required number of pulses into the controller and restart the automatic sausage enema machine to begin production.
