Description

Technical Field

[0001] This invention relates to the field of rice packaging technology, and in particular to a rice shaping vacuum packaging machine. Background Technology

[0002] A rice shaping vacuum packaging machine is a specialized device for quantitatively shaping and vacuum packaging rice. By removing air from the packaging, it can significantly slow down the rate of rice oxidation and deterioration, prevent insect pests and mold growth, effectively extend the shelf life of rice, and maintain its freshness and original flavor. The workflow typically includes steps such as quantitative packaging, shaping, and vacuum packaging. Quantitative packaging involves setting the weight of rice for each package as needed. Shaping involves shaping the rice and packaging into a fixed shape for easy packaging and storage. Vacuum packaging involves removing the air from the packaging bag to achieve a vacuum or near-vacuum state, and then sealing the packaging.

[0003] Currently, in the shaping and vacuum packaging process, fixed molds are typically used to shape the rice and packaging bags. When the packaging size needs to be changed, the mold needs to be disassembled and replaced, which reduces the practicality and flexibility of the equipment and requires the preparation of multiple mold sizes, increasing production costs. Secondly, existing shaping and vacuum packaging machines usually use a vibration platform to drive the mold, packaging bag, and rice inside the packaging bag to vibrate. The continuous slight vibration helps the rice grains to be arranged more tightly together and effectively expel air. However, for different varieties of rice, different vacuuming requirements, and different grain density requirements, a single vibration platform cannot perform targeted shaping operations, resulting in less than ideal air expulsion and shaping effects.

[0004] Therefore, in order to improve the practicality and flexibility of the equipment, and to improve the exhaust and shaping effects, this invention provides a rice shaping vacuum packaging machine. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art, and to propose a rice shaping vacuum packaging machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rice shaping vacuum packaging machine, comprising a packaging machine body, the packaging machine body being composed of left and right guide rails and left and right symmetrically installed support panels, and a drive mechanism and a feeding platform being respectively arranged on the guide rails from front to back, a vacuum cover being slidably assembled between the two support panels, and two left and right symmetrical size adjustment mechanisms and shaping mechanisms being arranged on the drive mechanism.

[0007] The size adjustment mechanism includes two length shaping plates that are symmetrically arranged front to back for adjusting the shaping length and a width shaping component that is symmetrically arranged left to right for adjusting the shaping width. Both the length shaping plates and the width shaping component are provided with auxiliary plate components. The auxiliary plate components include three vertically distributed sliding seats 1 that are slidably connected front to back on the length shaping plates, and three sliding seats 2 that are slidably connected left to right on both the fixed shaping plate and the sliding shaping plate, and are corresponding to the height of the sliding seats 1. Shaping components are slidably connected left to right on the sliding seats 1, and shaping components are slidably connected front to back on the sliding seats 2.

[0008] The shaping mechanism includes a shaping drive assembly and a locking assembly. The locking assembly switches between two shaping modes by changing the combination of the shaping components: vertical stepped amplitude vibration shaping and vertical uniform amplitude vibration shaping. The left and right opposite support panels are connected to a spiral-shaped pressure plate that slides vertically.

[0009] In the aforementioned rice shaping vacuum packaging machine, the drive mechanism includes a support slide that is slidably connected to the guide rail via an electric slider, and front and rear drive frames are slidably connected to the support slide. Left and right drive frames, which are staggered with the front and rear drive frames, are slidably connected to the support slide. The front and rear drive frames and the left and right drive frames are all U-shaped with their openings facing upwards. Vibration motors are installed on the horizontal sections of the front and rear drive frames and the left and right drive frames.

[0010] In the above-mentioned rice shaping vacuum packaging machine, a mounting plate is installed on the top wall of the support carriage via a rubber pad. The front length shaping plate is slidably connected to the top wall of the mounting plate via an electric slider, and the rear length shaping plate is fixedly connected to the top wall of the mounting plate. The width shaping component includes two loop frames. One loop frame is slidably connected between the two corresponding length shaping plates via an electric slider, and the front part of the other loop frame is slidably connected to the front length shaping plate, and the rear part is fixedly connected to the rear length shaping plate.

[0011] In the above-mentioned rice shaping vacuum packaging machine, a fixed shaping plate is fixedly connected to the U-shaped frame, and a sliding groove is opened in the fixed shaping plate. A sliding shaping plate is slidably connected in the sliding groove through a spring. The front and rear corresponding length shaping plates and the left and right corresponding width shaping components together form a frame structure.

[0012] In the above-mentioned rice shaping vacuum packaging machine, the length shaping plate and the sliding seat are connected by a spring, and the fixed shaping plate and the sliding shaping plate are connected by a spring to the sliding seat.

[0013] In the above-mentioned rice shaping vacuum packaging machine, sliding seat one is connected to the corresponding shaping part by spring three in a left-right sliding connection, sliding seat two is connected to the corresponding shaping part in a front-back sliding connection by spring three, and the inside of the shaping part is connected to the connecting block by spring four in a vertical sliding connection. The upper and lower adjacent connecting blocks fit together, and the upper end of the uppermost connecting block is located outside the frame structure. The shaping part is provided with a positioning groove on the side near the center of the frame structure.

[0014] In the aforementioned rice shaping vacuum packaging machine, the shaping drive assembly includes a support plate corresponding to the front and back of the length shaping plate and the left and right of the width shaping component. The length shaping plate is slidably connected to a connecting piece group that is staggered vertically with the shaping component via spring five. The fixed shaping plate and the sliding shaping plate are slidably connected to corresponding connecting piece groups via spring five. Each connecting piece group includes two symmetrically distributed connecting pieces. A support rod is fixedly connected to the side of the connecting piece group away from the corresponding length shaping plate and the width shaping component. The support plate is slidably connected to the corresponding support rod via spring six.

[0015] In the above-mentioned rice shaping vacuum packaging machine, the support plate has protrusions distributed vertically on one side near the corresponding length shaping plate and width shaping component, and a shock-absorbing spring 1 is installed on the support plate above the protrusions. A shock-absorbing spring 2 is installed on the upper protrusion, and the thickness of the lower protrusion is greater than the thickness of the upper protrusion.

[0016] In the above-mentioned rice shaping vacuum packaging machine, the locking component includes upper and lower sliding rods, and the upper and lower sliding rods are slidably connected inside the support plate by spring seven. A positioning block corresponding to the positioning groove is slidably connected to the support plate along its thickness direction by spring eight. A wedge block two is fixedly connected to the positioning block, and the upper side wall of the wedge block two is inclined. A wedge block one corresponding to the wedge block two is fixedly connected to the upper and lower sliding rods, and the lower side wall of the wedge block one is inclined to match the wedge block two.

[0017] In the above-mentioned rice shaping vacuum packaging machine, the U-shaped lower pressure plate corresponds to the connecting block and the upper and lower sliding rods, the front and rear drive frames correspond to the front and rear distributed support plates, and the left and right drive frames correspond to the left and right distributed support plates.

[0018] Compared with existing technologies, the advantages of this invention are: 1. By cooperating with the length shaping plate, the width shaping component and the auxiliary plate component, the distance between the two width shaping components is changed to adjust the width of the packaged rice, and the distance between the two length shaping plates is changed to adjust the length of the packaged rice, thereby improving the flexibility of rice packaging size changes, eliminating the need to prepare molds of multiple sizes, and saving costs.

[0019] 2. Through the coordinated use of the drive mechanism, size adjustment mechanism, and shaping mechanism, this system minimizes the amount of air inside the packaging and optimizes the arrangement and density of grains, especially for rice with higher requirements for vacuuming and grain compactness. When the support plate vibrates, it drives the shaping components from bottom to top to vibrate in a step-like manner, from strong to weak. This results in the shaping components performing a step-like shaping operation on the packaging bag and the rice inside the bag, with the lower part being stronger and the upper part being weaker. The higher vibration frequency ensures that the bottom layer of rice is tightly arranged, and the step-like shaping operation ensures that the rice in the packaging is evenly distributed.

[0020] 3. Through the cooperation of the drive mechanism, size adjustment mechanism and shaping mechanism, for rice that is hard and sharp and easily punctures the packaging, and for rice with low requirements for grain density, the downward movement of the U-shaped pressure plate drives multiple vertically distributed shaping parts to connect into a whole. At the same time, the support plate connects with the corresponding shaping parts to form a whole. The support plate pushes the multiple shaping parts that have become a whole to vibrate synchronously, and performs synchronous vibration shaping operation on the packaging bag and the rice inside the packaging bag from four directions: front, back, left and right, to quickly arrange the rice grains. The shaping effect can be changed by changing the combination of auxiliary plate components. Attached Figure Description

Detailed Implementation

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 2 A rice shaping vacuum packaging machine includes a packaging machine body 1, which consists of left and right guide rails and left and right symmetrically installed support panels. A drive mechanism 2 and a feeding table 6 are respectively arranged between the guide rails from front to back. A vacuum cover 5 is slidably assembled between the two support panels. The drive mechanism 2 is provided with two left and right symmetrical size adjustment mechanisms 3 for rapid size change and a shaping mechanism 4 for shaping the packaging bag and the rice inside the packaging bag.

[0034] The initial position of the drive mechanism 2 is located at the front of the guide rail, so that the packaging bag is fed by the bagging mechanism (existing equipment, not shown in the figure, and will not be described in detail here). The rice is fed into the packaging bag by the feeding mechanism (existing equipment, not shown in the figure, and will not be described in detail here). The drive mechanism 2, the size adjustment mechanism 3 and the shaping mechanism 4 work together to shape the rice in the packaging bag by vibration, so that it and the packaging bag become a regular rectangle. The drive mechanism 2 moves the rice and the packaging bag to the bottom of the vacuum hood 5 for shaping. The vacuum hood 5 performs vacuuming and sealing operations on the rice and packaging (using existing technology, which will not be described in detail here). Finally, the vacuum-packed rice is moved to the unloading platform 6 for unloading.

[0035] Reference Figures 1 to 3The drive mechanism 2 includes a support slide 21 that is slidably connected to the guide rail via an electric slider. Front and rear drive frames 22 are slidably connected to the support slide 21. Left and right drive frames 23, which are slidably connected to the support slide 21 and are staggered with the front and rear drive frames 22, are also slidably connected to the support slide 21. The front and rear drive frames 22 and the left and right drive frames 23 are all U-shaped with their openings facing upwards. Vibration motors 24 are installed on the horizontal sections of the front and rear drive frames 22 and the left and right drive frames 23.

[0036] Vibration motors 24 mounted on the front and rear drive frames 22 drive the front and rear drive frames 22 to vibrate back and forth, and vibration motors 24 mounted on the left and right drive frames 23 drive the left and right drive frames 23 to vibrate left and right. The impact of vibration on other structures can be reduced by installing vibration isolation pads; the specific installation location will be determined according to actual needs.

[0037] Reference Figure 1 , Figure 4 and Figure 5 The size adjustment mechanism 3 includes two length shaping plates 31 that are symmetrically arranged front and back for adjusting the length of the rice packaging and a width shaping component 32 that is symmetrically arranged left and right for adjusting the width of the rice packaging. Both the length shaping plates 31 and the width shaping component 32 are provided with auxiliary plate components 33 for performing shaping operations. The top wall of the support slide 21 is equipped with an installation plate through a rubber pad. The front length shaping plate 31 is slidably connected to the top wall of the installation plate through an electric slider, and the rear length shaping plate 31 is fixedly connected to the top wall of the installation plate.

[0038] Reference Figures 5 to 6 The width shaping component 32 includes a loop frame 321. One loop frame 321 is slidably connected between two corresponding length shaping plates 31 via an electric slider (the loop frame 321 can slide back and forth relative to the length shaping plates 31, and can also slide left and right relative to the length shaping plates 31). The front part of the other loop frame 321 is slidably connected to the corresponding length shaping plate 31 on the front side, and the rear part is fixedly connected to the corresponding length shaping plate 31 on the rear side. A fixed shaping plate 322 is fixedly connected to the loop frame 321. A sliding groove is provided in the fixed shaping plate 322. A sliding shaping plate 323 is slidably connected to the sliding groove via a spring (not shown in the figure). The corresponding length shaping plates 31 on the front and back and the corresponding width shaping components 32 on the left and right together form a frame structure.

[0039] The size adjustment mechanism 3 can adjust the size of the packaged rice. The specific operation is as follows: the electric slider drives the slidingly connected loop frame 321 to slide on the corresponding length shaping plate 31 to another loop frame 321. The distance between the two width shaping components 32 changes to adjust the width of the packaged rice. The electric slider drives the front length shaping plate 31 to slide to the rear length shaping plate 31. The distance between the two length shaping plates 31 changes to adjust the length of the packaged rice. The length shaping plate 31 pushes the sliding shaping plate 323 to slide into the corresponding fixed shaping plate 322 to make adaptive changes, improve the flexibility of rice packaging size changes, and eliminate the need to prepare molds of multiple sizes, saving costs.

[0040] Reference Figures 5 to 7 The auxiliary plate assembly 33 includes a shaping component 331. Three sliding seats 1, evenly distributed vertically, are slidably connected to the length shaping plate 31 via spring 2 (not shown in the figure). Three sliding seats 2, corresponding to the height of the sliding seats 1, are slidably connected to the fixed shaping plate 322 and the sliding shaping plate 323 via spring 2. The corresponding shaping component 331 is slidably connected to the sliding seat 1 via spring 3. The corresponding shaping component 331 is slidably connected to the sliding seat 2 via spring 3 (not shown in the figure). The interior of each shaping component 331 is slidably connected to a connecting block 332 via spring 4 (not shown in the figure). The upper and lower adjacent connecting blocks 332 fit together, and the uppermost connecting block 332 is located outside the frame structure. The shaping component 331 is provided with a positioning groove 333 on the side near the center of the frame structure.

[0041] Reference Figures 4 to 5 The shaping mechanism 4 includes a shaping drive assembly 41 and a locking assembly 42. The shaping drive assembly 41 is used to drive the auxiliary plate assembly 33 to perform operations. The locking assembly 42 changes the shaping effect by changing the combination of the auxiliary plate assembly 33. The left and right opposite support panels are connected to the spiral-shaped pressure plate 43 by an electric slider.

[0042] Reference Figure 5 , Figure 7 , Figure 8 and Figure 9The shaping drive assembly 41 includes a support plate 411 corresponding to the front and back of the length shaping plate 31 and to the left and right of the width shaping assembly 32. A connecting member group 413, which is vertically staggered with the shaping member 331, is slidably connected to the length shaping plate 31 via a spring (not shown in the figure). Corresponding connecting member groups 413 are slidably connected to the fixed shaping plate 322 and the sliding shaping plate 323 via springs. Each connecting member group 413 includes two symmetrically distributed connecting members, with the connecting member group 413 located away from the corresponding length shaping member. Support rods are fixedly connected to one side of both the length shaping plate 31 and the width shaping component 32. The support plate 411 is slidably connected to the corresponding support rod by a spring six (not shown in the figure). Protrusions 412 are distributed vertically on the side of the support plate 411 near the corresponding length shaping plate 31 and width shaping component 32. A shock-absorbing spring one is installed on the support plate 411 above the protrusion 412. A shock-absorbing spring two is installed on the upper protrusion 412. The thickness of the lower protrusion 412 is greater than the thickness of the upper protrusion 412.

[0043] Reference Figure 2 , Figure 8 , Figure 9 and Figure 10 The locking assembly 42 includes an upper and lower sliding rod 421. The upper and lower sliding rod 421 is slidably connected to the inside of the support plate 411 by a spring seven (not shown in the figure). The support plate 411 is slidably connected to a positioning block 424 corresponding to the positioning groove 333 by a spring eight (not shown in the figure) along its thickness direction. A second wedge 423 is fixedly connected to the positioning block 424. The upper side wall of the second wedge 423 is inclined. A first wedge 422 corresponding to the second wedge 423 is fixedly connected to the upper and lower sliding rod 421. The lower side wall of the first wedge 422 is inclined to match the second wedge 423. The U-shaped lower pressure plate 43 corresponds to the connecting block 332 and the upper and lower sliding rod 421. The front and rear drive frames 22 correspond to the front and rear distributed support plates 411. The left and right drive frames 23 correspond to the left and right distributed support plates 411.

[0044] By cooperating with the drive mechanism 2, the size adjustment mechanism 3 and the shaping mechanism 4, it is possible to accurately shape different varieties of rice with different shaping requirements.

[0045] For rice varieties with high stickiness, such as glutinous rice, or lighter or smaller rice varieties, stricter moisture-proof measures are required during storage. Higher vacuuming standards and tighter grain density are also necessary. The specific shaping operation is as follows: the front and rear drive frames 22 and the left and right drive frames 23 push the corresponding support plate 411 to vibrate as a whole. The upper part of the support plate 411 is in contact with the upper shaping component 331 via a shock-absorbing spring 1. The middle part of the support plate 411 is in contact with the middle shaping component 331 via a shock-absorbing spring 2 and a protrusion 412. The lower part of the support plate 411 is in contact with the protrusion 412. 412 is attached to the lower shaping component 331. When the support plate 411 vibrates, it drives the shaping component 331 from bottom to top to vibrate from strong to weak. Thus, the shaping component 331 performs a step-like shaping operation on the packaging bag and the rice inside the packaging bag with strong vibration at the bottom and weak vibration at the top. Since the air is more difficult to expel from the lower layer of rice than the upper layer of rice, a higher vibration frequency is used to ensure that the bottom layer of rice is tightly arranged. The step-like shaping operation ensures that the rice in the packaging is evenly distributed, minimizes the amount of air in the packaging, and optimizes the arrangement and compactness of the grains.

[0046] For rice that is hard and sharp, easily punctures packaging, or rice with low grain density requirements, the specific shaping operation is as follows: The electric slider drives the U-shaped lower pressure plate 43 to move downward relative to the support panel. The downward movement of the U-shaped lower pressure plate 43 drives the connecting block 332 to move downward in the corresponding shaping component 331. The upper connecting block 332 pushes the middle connecting block 332 downward, and the middle connecting block 332 pushes the lower connecting block 332 downward until the upper connecting block 332 connects the upper shaping component 331 and the middle shaping component 331, and the middle connecting block 332 connects the middle shaping component 331 and the lower shaping component 331, thereby connecting the three vertically distributed shaping components 331 into a whole.

[0047] Simultaneously, the downward movement of the U-shaped pressure plate 43 drives the downward movement of the upper and lower sliding rods 421. The downward movement of the upper and lower sliding rods 421 causes the first wedge 422 to approach the second wedge 423. The inclined surface of the first wedge 422 gradually presses against the inclined surface of the second wedge 423 and pushes the second wedge 423 and the positioning block 424 to slide closer to the corresponding shaping component 331 from inside the support plate 411 until the positioning block 424 engages with the corresponding positioning groove 333, thereby connecting the support plate 411 and the corresponding shaping component 331 into a whole. When the front and rear drive frames 22 and the left and right drive frames 23 push the corresponding support plate 411 to vibrate as a whole, the support plate 411 pushes the multiple shaping components 331, which are now a whole, to vibrate synchronously. The packaging bag and the rice inside the packaging bag are simultaneously vibrated and shaped from four directions: front, rear, left, and right. The upper and lower layers of rice are subjected to the same intensity. By controlling the vibration intensity of the vibration motor, the air in the rice inside the packaging bag is not completely expelled, and the rice is not compressed too tightly, which increases the risk of rice grains puncturing the packaging.

[0048] The upper connecting block 332 and the top wall of the upper and lower sliding rods 421 can reduce the friction between the upper connecting block 332 and the bottom wall of the lower sliding plate 43 during vibration by installing ball bearings.

[0049] The specific operating steps of this rice shaping vacuum packaging machine are as follows: the distance between the two width shaping components 32 is changed by the electric slider to adjust the width of the packaged rice, and the distance between the two length shaping plates 31 is changed to adjust the length of the packaged rice, thereby improving the flexibility of rice packaging size changes.

[0050] The front and rear drive frames 22 and the left and right drive frames 23 drive the corresponding support plates 411 to vibrate as a whole. For rice with higher vacuum requirements and higher grain density requirements, the shaping component 331 performs a stepped shaping operation on the packaging bag and the rice inside the packaging bag with stronger bottom and weaker top. The stepped shaping operation ensures that the rice in the packaging is evenly distributed and minimizes the amount of air in the packaging. For rice that is harder and sharper, easily punctures the packaging, or has lower grain density requirements, the U-shaped lower pressure plate 43 moves down to drive the connecting block 332 and the upper and lower sliding rods 421 to move down. After the multiple vertically distributed shaping components 331 are connected into a whole, the support plate 411 and the corresponding shaping component 331 are connected into a whole. The support plate 411 drives the multiple shaping components 331 that have become a whole to vibrate synchronously, so that the rice in the packaging is evenly distributed over a large area.

[0051] Vacuum hood 5 performs vacuuming and sealing operations on rice and packaging, and finally moves the vacuum-packed rice to unloading platform 6 for unloading.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
