Description

Technical Field

[0001] This invention belongs to the field of raw material mixing technology, and particularly relates to a raw material mixing device for canning. Background Technology

[0002] In the canning industry, raw material mixing is a crucial step affecting the taste and quality of the product. Traditional fruit pulp mixing devices mostly use high-speed stirring or static soaking methods, which have significant shortcomings:

[0003] Poor pulp integrity: Mechanical stirring can easily cause the pulp to break, affecting the texture of the canned fruit.

[0004] Uneven mixing of juices: Drinking water and fruit juice are difficult to mix fully, and separation is likely to occur.

[0005] Low extrusion efficiency: Existing roller pressing equipment cannot dynamically adjust the extrusion pressure. Excessive extrusion can easily damage the pulp structure, while light extrusion leads to insufficient juice yield.

[0006] Some improvement solutions attempt to optimize the mixing effect by adding extrusion rollers or guide holes, but limitations still exist:

[0007] The static extrusion mechanism cannot adapt to different pulp firmness, resulting in fluctuations in juice yield;

[0008] The lack of precise control over the rolling path of the fruit pulp increases the risk of pulp breakage due to localized stress concentration.

[0009] Therefore, there is an urgent need to develop a stirring device that can balance the integrity of the fruit pulp, efficient juice extraction, and uniform mixing, so as to improve the blending degree of the juice while ensuring that the shape of the fruit pulp particles meets the quality requirements of canned goods. Summary of the Invention

[0010] The purpose of this invention is to provide a raw material mixing device for canning, which aims to solve the problem that existing raw material mixing devices for canning lack precise control over the rolling path of fruit pulp, and that local stress concentration exacerbates the risk of fruit pulp breakage.

[0011] The present invention is implemented as follows: a raw material mixing device for canning includes an outer shell, a sleeve fixedly connected to the center of the outer shell, a conveying mechanism for vertically conveying fruit pulp is provided in the sleeve, a discharge port is provided near the upper end of the sleeve, a rotating sleeve is rotatably connected to the outside of the discharge port, and a mixing sleeve is connected to the rotating sleeve. The mixing sleeve can rotate horizontally under the drive of the conveying mechanism.

[0012] The mixing sleeve has several guide holes on both sides. The mixing sleeve also has movable sealing components on both sides that can partially cover the guide holes. The movable sealing components can move vertically along the surface of the mixing sleeve. The mixing sleeve is equipped with an extrusion mechanism and a limiting component. The extrusion mechanism is vertically inclined, and the bottom of the extrusion mechanism forms an angle with the limiting component that is smaller than the angle of the guide holes. The extrusion mechanism can roll the pulp by reciprocating horizontally relative to the limiting component. The mixing sleeve has a discharge port at its lower end.

[0013] In a further technical solution, the mobile enclosure assembly includes a second motor, a threaded shaft, and a baffle plate;

[0014] Both sides of the mixing sleeve are vertically slidably connected with baffles. The upper end of the mixing sleeve is fixedly connected with two No. 2 motors. The output shafts of the No. 2 motors are fixedly connected with threaded shafts, and the threaded shafts are threadedly connected to the baffles on one side.

[0015] A further technical solution is that the extrusion mechanism includes a sliding seat, a first electric telescopic rod, a third motor, an extrusion plate, and an extrusion strip;

[0016] The side of the mixing sleeve is provided with a sliding seat, and the sliding seat is fixedly connected to a first electric telescopic rod. The telescopic end of the first electric telescopic rod is fixedly connected to a third motor. The output shaft of the third motor is fixedly connected to an extrusion plate, and several extrusion strips are arranged side by side on the extrusion plate.

[0017] In a further technical solution, the sliding seat is slidably connected to the side of the mixing sleeve, and a retractable second electric telescopic rod is connected between the sliding seat and the mixing sleeve.

[0018] In a further technical solution, the limiting component includes a limiting plate, a limiting strip, and a through hole;

[0019] The limiting plate is fitted into the inner wall of the mixing sleeve. Several limiting strips are arranged side by side on the limiting plate. Several through holes are provided on the limiting plate, and all through holes coincide with the guide holes on the side of the mixing sleeve.

[0020] A pressure sensor is installed between the limiting plate and the inner wall of the mixing sleeve. The pressure sensor is electrically connected to the PLC controller and the data processor in sequence. The PLC controller is electrically connected to the conveying mechanism and the extrusion mechanism.

[0021] A further technical solution involves all extrusion strips being inclined relative to the vertical, and all limit strips being set vertically.

[0022] In a further technical solution, the conveying mechanism includes a No. 1 motor, a rotating shaft, and driving blades;

[0023] The No. 1 motor is fixedly connected to the bottom surface of the outer casing. The output shaft of the No. 1 motor is fixedly connected to a rotating shaft. The rotating shaft is provided with pushing blades in a vertical spiral. A connecting rod is fixedly connected between the rotating shaft and the upper end face of the mixing sleeve.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] The conveying mechanism transports the fruit pulp and drinking water from the bottom of the outer shell upwards along the sleeve. Then, the fruit pulp and drinking water enter the mixing sleeve through the rotating sleeve. In the mixing sleeve, due to the inclined setting of the extrusion mechanism, the fruit pulp is intercepted and squeezed by the extrusion mechanism. Under the extrusion action of the extrusion mechanism and the limiting component, the juice in the fruit pulp mixes with the drinking water to form fruit juice. In this way, the fruit pulp can be squeezed out of juice and fully mixed with drinking water. In this process, the integrity of the fruit pulp can be better maintained, and the taste of the canned food can be improved.

[0026] During the rotation of the mixing sleeve, the juice in the outer shell enters the mixing sleeve through the guide holes on the mixing sleeve. At this time, the moving sealing component on the front side of the mixing sleeve closes the guide holes on the lower side of the mixing sleeve, and the moving sealing component on the back side of the mixing sleeve closes the guide holes on the upper side of the mixing sleeve. Thus, the juice enters the mixing sleeve and is discharged from top to bottom. Under the hydraulic pressure of the juice, the squeezing force between the pulp and the squeezing mechanism and the limiting component can be increased, improving the squeezing effect of the pulp. Furthermore, the juice squeezed out by the pulp can be fully mixed with the remaining juice in the outer shell, improving the mixing effect of the juice.

[0027] Motor No. 3 drives the extrusion plate to rotate. At this time, the angle between the extrusion plate and the limiting component can be changed. When the angle between the extrusion plate and the limiting component is larger, the degree of compression of the pulp changes more within a unit distance of vertical movement. As a result, the pulp is subjected to greater changes in the degree of compression during the extrusion process. At this time, the pulp is extruded at a faster rate, but the pulp is easily crushed. Conversely, the extrusion rate of the pulp is slower, but the pulp remains more intact during the extrusion process. Therefore, by changing the angle between the extrusion plate and the limiting component, a balance can be achieved between the extrusion rate of the pulp and the integrity of the pulp output.

[0028] All the extrusion strips are set at an angle relative to the vertical, while all the limiting strips are set vertically. When the extrusion plate moves relative to the limiting plate, the extrusion plate drives all the extrusion strips to apply oblique extrusion force to the pulp. The pulp rolls obliquely back and forth along the surface of the limiting plate, which makes the outer surface of the pulp more evenly stressed, improving the juice yield of the pulp while enhancing the overall protection of the pulp.

[0037] 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 and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] like Figures 1-7 As shown, a raw material mixing device for canning provided in one embodiment of the present invention includes a shell 1, a sleeve 2 fixedly connected to the center of the shell 1, a conveying mechanism 3 for vertically conveying fruit pulp is provided in the sleeve 2, a discharge port 10 is provided near the upper end of the sleeve 2, a rotating sleeve 11 is rotatably connected to the outside of the discharge port 10, and a mixing sleeve 5 is connected to the rotating sleeve 11. The mixing sleeve 5 can rotate horizontally under the drive of the conveying mechanism 3.

[0040] The mixing sleeve 5 has several guide holes 9 on both its front and back sides. The mixing sleeve 5 also has movable sealing components 6 on both its front and back sides that can partially cover the guide holes 9. The movable sealing components 6 can move vertically along the surface of the mixing sleeve 5. The mixing sleeve 5 is provided with an extrusion mechanism 7 and a limiting component 8. The extrusion mechanism 7 is vertically inclined, and the bottom of the extrusion mechanism 7 forms an angle of less than 90 degrees with the limiting component 8. The extrusion mechanism 7 can roll the pulp by reciprocating horizontally relative to the limiting component 8. The mixing sleeve 5 has a discharge port 4 at its lower end.

[0041] In this embodiment, drinking water and fruit pulp are poured into the outer shell 1. At this time, the conveying mechanism 3 is activated, and the conveying mechanism 3 drives the mixing sleeve 5 to mix and stir in the outer shell 1. During this process, the conveying mechanism 3 conveys the fruit pulp and drinking water at the bottom of the outer shell 1 upward along the sleeve 2. Then, the fruit pulp and drinking water enter the mixing sleeve 5 through the rotating sleeve 11. In the mixing sleeve 5, due to the inclined setting of the extrusion mechanism 7, the fruit pulp is intercepted and extruded by the extrusion mechanism 7. Under the extrusion action of the extrusion mechanism 7 and the limiting component 8, the juice in the fruit pulp mixes with the drinking water to form fruit juice. When the fruit pulp is extruded and reduced to a certain volume, the fruit pulp is discharged from the discharge port 4 on the lower side of the mixing sleeve 5. In this way, the fruit pulp can be squeezed to extract juice and fully mixed with drinking water. In this process, the integrity of the fruit pulp can also be well maintained, and the taste of the canned food can be improved.

[0042] During the rotation of the mixing sleeve 5, the juice in the outer shell 1 enters the mixing sleeve 5 through the guide hole 9 on the mixing sleeve 5. At this time, the movable sealing component 6 on the front side of the mixing sleeve 5 closes the guide hole 9 on the lower side of the mixing sleeve 5, and the movable sealing component 6 on the back side of the mixing sleeve 5 closes the guide hole 9 on the upper side of the mixing sleeve 5. Thus, after the juice enters the mixing sleeve 5, it is discharged from top to bottom. Under the hydraulic pressure of the juice, the squeezing force between the pulp and the squeezing mechanism 7 and the limiting component 8 can be increased, improving the squeezing effect of the pulp. Moreover, the juice squeezed out by the pulp can be fully mixed with the remaining juice in the outer shell 1, improving the mixing effect of the juice.

[0043] like Figure 4 As shown, in a preferred embodiment of the present invention, the movable enclosure component 6 includes a second motor 61, a threaded shaft 62, and a baffle plate 63.

[0044] Both sides of the mixing sleeve 5 are vertically slidably connected with baffle plates 63. The upper end of the mixing sleeve 5 is fixedly connected with two second motors 61. The output shafts of the second motors 61 are fixedly connected with threaded shafts 62. The threaded shafts 62 are threadedly connected to the baffle plates 63 on one side.

[0045] In this embodiment, the second motor 61 is started, which drives the threaded shaft 62 to rotate. The threaded shaft 62 drives the baffle plate 63 to move vertically through the threaded transmission. The baffle plates 63 on both sides of the mixing sleeve 5 can shield the guide holes 9 on the two sides of the mixing sleeve 5. Specifically:

[0046] When the baffle plate 63 on the front side of the mixing sleeve 5 is located on the lower side of the mixing sleeve 5, and the baffle plate 63 on the back side of the mixing sleeve 5 is located on the upper side of the mixing sleeve 5, the juice in the outer shell 1 enters the mixing sleeve 5 and flows out from top to bottom. At this time, the hydraulic pressure of the juice can increase the squeezing force between the pulp and the squeezing mechanism 7 and the limiting component 8, thereby improving the pulp's liquid output effect.

[0047] When the baffle plate 63 on the front side of the mixing sleeve 5 is on the upper side of the mixing sleeve 5, and the baffle plate 63 on the back side of the mixing sleeve 5 is on the lower side of the mixing sleeve 5, when the juice in the outer shell 1 enters the mixing sleeve 5 from the lower side, under the guidance of the inclined extrusion mechanism 7, some of the juice flows upward. Under the push of hydraulic force, the extrusion pressure between the pulp and the extrusion mechanism 7 and the limiting component 8 is reduced, thus preventing the pulp from being excessively extruded and broken.

[0048] like Figure 6 As shown, in a preferred embodiment of the present invention, the extrusion mechanism 7 includes a sliding seat 71, a first electric telescopic rod 72, a third motor 73, an extrusion plate 74, and an extrusion strip 75.

[0049] The side of the mixing sleeve 5 is provided with a sliding seat 71, and the sliding seat 71 is fixedly connected to a first electric telescopic rod 72. The telescopic end of the first electric telescopic rod 72 is fixedly connected to a third motor 73. The output shaft of the third motor 73 is fixedly connected to an extrusion plate 74, and several extrusion strips 75 are arranged side by side on the extrusion plate 74.

[0050] In this embodiment, the telescopic part of the sliding seat 71 is activated to extend and retract, and the telescopic part of the sliding seat 71 drives the extrusion plate 74 to move horizontally back and forth. The extrusion plate 74 pushes the pulp to roll along the surface of the limiting component 8, thereby extruding the pulp.

[0051] When motor 73 is started, it rotates, driving the extrusion plate 74 to rotate. The angle between the extrusion plate 74 and the limiting component 8 can be changed. A larger angle results in greater variation in the degree of compression per unit distance the fruit pulp moves vertically, leading to faster juice extraction but also making the pulp more prone to breakage. Conversely, a smaller angle results in less variation in the degree of compression per unit distance the fruit pulp moves vertically, leading to slower juice extraction but better pulp integrity during extraction. Therefore, by changing the angle between the extrusion plate 74 and the limiting component 8, a balance can be achieved between the juice extraction speed and the integrity of the extracted pulp.

[0052] like Figure 6 As shown, in a preferred embodiment of the present invention, the sliding seat 71 is slidably connected to the side of the mixing sleeve 5, and a retractable second electric telescopic rod 13 is connected between the sliding seat 71 and the mixing sleeve 5.

[0053] In this embodiment, the second electric telescopic rod 13 is activated, which drives the extrusion plate 74 to move relative to the limiting component 8. At this time, the distance between the extrusion plate 74 and the limiting component 8 can be adjusted, thereby adjusting the volume of the pulp after extrusion.

[0054] like Figure 7 As shown, in a preferred embodiment of the present invention, the limiting component 8 includes a limiting plate 81, a limiting strip 82, and a through hole 83;

[0055] The limiting plate 81 is fitted into the inner wall of the mixing sleeve 5. Several limiting strips 82 are arranged side by side on the limiting plate 81. Several through holes 83 are provided on the limiting plate 81, and all through holes 83 coincide with the guide holes 9 on the side of the mixing sleeve 5.

[0056] A pressure sensor is provided between the limiting plate 81 and the inner wall of the mixing sleeve 5. The pressure sensor is electrically connected to the PLC controller and the data processor in sequence. The PLC controller is electrically connected to the conveying mechanism 3 and the extrusion mechanism 7.

[0057] In this embodiment, the pulp is squeezed by the cooperation of the limiting strip 82 and the squeezing strip 75. When the squeezing plate 74 moves back and forth parallel to the surface of the limiting plate 81, the limiting strip 82 on the limiting plate 81 pushes the pulp to roll between the squeezing strips 75, thereby squeezing the pulp.

[0058] When the pressure sensor indicates that the squeezing pressure between the pulp and the limiting plate 81 exceeds the pressure threshold of the data processor, the data processor controls the baffles 63 on both sides of the mixing sleeve 5 to change their positions via the PLC controller (so that the baffles 63 on the front side of the mixing sleeve 5 are on the upper side, and the baffles 63 on the back side of the mixing sleeve 5 are on the lower side). At this time, in the mixing sleeve 5, some juice flows upward along the space between the extrusion plate 74 and the limiting plate 81. Under the pressure of the juice, the squeezing pressure between the pulp and the limiting strip 82 and the extrusion strip 75 is reduced, thereby protecting the pulp. At this time, reducing the extension speed of the first electric telescopic rod 72 can change the extrusion speed of the extrusion strip 75 on the pulp, thereby quickly adjusting the extrusion pressure on the pulp after it is subjected to a large extrusion pressure, thus protecting the pulp and preventing it from being continuously squeezed and broken.

[0059] like Figure 6 and Figure 7 As shown, in a preferred embodiment of the present invention, all extrusion strips 75 are inclined relative to the vertical, and all limiting strips 82 are vertically arranged.

[0060] In this embodiment, since the bottom of the extrusion plate 74 and the limiting strip 82 form an angle of less than 90 degrees, if all the extrusion strips 75 are set vertically, when the extrusion plate 74 moves relative to the limiting plate 81, the extrusion strips 75 on the extrusion plate 74 push the pulp to roll back and forth in the horizontal direction. As a result, the bottom of the pulp is subjected to greater extrusion force, while the upper part of the pulp is subjected to less extrusion force. After continuous extrusion, the juice yield of the pulp is low and the pulp is easy to break.

[0061] In this embodiment, all the extrusion strips 75 are inclined relative to the vertical, while all the limiting strips 82 are vertically arranged. When the extrusion plate 74 moves relative to the limiting plate 81, the extrusion plate 74 drives all the extrusion strips 75 to apply oblique extrusion force to the pulp. The pulp rolls obliquely back and forth along the surface of the limiting plate 81, which makes the outer surface of the pulp more evenly stressed, improves the juice yield of the pulp and enhances the overall protection effect of the pulp.

[0062] like Figure 3 As shown, in a preferred embodiment of the present invention, the conveying mechanism 3 includes a primary motor 31, a rotating shaft 32, and a pushing blade 33;

[0063] The first motor 31 is fixedly connected to the bottom surface of the outer casing 1. The output shaft of the first motor 31 is fixedly connected to a rotating shaft 32. The rotating shaft 32 is provided with a pushing blade 33 in a vertical spiral. A connecting rod 12 is fixedly connected between the rotating shaft 32 and the upper end surface of the mixing sleeve 5.

[0064] In this embodiment, motor 31 is started, which drives shaft 32 to rotate. Shaft 32 drives blade 33 to vertically transport the pulp and juice at the bottom of the outer shell 1.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
