Description

Technical Field

[0001] The utility model relates to the field of vacuum packaging auxiliary components for prepared dishes, in particular to vacuum packaging equipment for prepared dishes. Background Art

[0002] Pre-prepared meals generally refer to semi-finished products made from various agricultural, livestock, poultry, and aquatic products as raw materials, supplemented with seasonings and other auxiliary materials, and processed through pre-selection, modulation and other processes. Usually, pre-prepared meals need to be stored or transported under cold chain conditions for consumers to eat after simple heating or cooking. Specifically in the processing of pre-prepared meals, a vacuum packaging machine is needed to vacuum-pack the pre-prepared meals, so as to evacuate and seal the packaging bags of the pre-prepared meals, so as to achieve the purpose of long-term preservation. During the specific work, it only needs to press the vacuum cover to automatically complete the vacuuming, preservation, and freshness preservation to extend the storage period of the product, seal, and after vacuum packaging, it can automatically pull out the package. The packaged food can prevent mildew.

[0003] However, in the specific design of the current vacuum packaging machine, when vacuum packaging the packaging bag, the packaging bag is usually placed flat on the operating table. As a result, when packaging the pre-prepared food, the pre-prepared food is easily out of the bag opening. At the same time, if the pre-prepared food contains soup, the soup will directly spill out. The vacuum packaging operation is very inconvenient, and the operator is often required to manually stand up the pre-prepared food packaging bag so that the bag opening is at the top, and then adapt the top bag opening to the vacuum packaging machine to complete the vacuum packaging by turning it horizontally. This has low efficiency and a large workload. Utility Model Content

The purpose of this arrangement is to firstly allow the pre-prepared food packaging bag to be placed upright in the storage box body 3 by the push-stop plate 408 and the card plate 403 of the bag body anti-falling assembly 4 from the outside to limit the pre-prepared food packaging bag, thereby replacing the bag anti-falling method of the operator manually holding the pre-prepared food packaging bag by hand. At the same time, the distance between the push-stop plate 408 and the inner surface of the storage box body 3 can be adjusted by adjusting the stud 406 in the forward and reverse directions, thereby being able to limit the bag anti-falling of pre-prepared food packaging bags of different thicknesses, thereby achieving the bag anti-falling restriction of pre-prepared food packaging bags of different specifications.

[0034] See also Figures 1-4As shown, the top surface of the operating table 101 is equipped with quick-release assembly components 2 at the front and rear positions of the storage box body 3, and the storage box body 3 is detachably fixed to the top surface of the operating table 101 through the quick-release assembly components 2. Specifically, the quick-release assembly components 2 include an L-shaped mounting bracket 201 and a limiting plug rod 205. The top surface of the operating table 101 is fixedly equipped with L-shaped mounting brackets 201 at the front and rear positions of the storage box body 3, and the storage box body 3 is stuck in the vertical part of the L-shaped mounting bracket 201 at the front and rear positions in a vertical sliding fit manner. The vertical parts of the L-shaped mounting brackets 201 at the front and rear positions are provided with mounting holes 206 in the longitudinal direction, and the front and rear positions of the storage box body 3 are provided with limited position holes 207 in the longitudinal direction, and the limited position holes 207 are longitudinally coaxially matched with the mounting holes 206, and the mounting holes 206 are coaxially inserted with the limited position rods 205 in a longitudinal sliding manner, and the inner ends of the limit rods 205 at the front and rear positions close to each other are longitudinally slidably matched with the corresponding limit holes 207, and the limit rods 205 at the front and rear positions are longitudinally slidably matched. The outer ends away from each other extend outward from the outer end faces of the vertical parts of the corresponding L-shaped mounting bracket 201 and are coaxially fixed with handles 203. The portion of the limiting rod 205 located between the corresponding handle 203 and the outer end faces of the vertical parts of the L-shaped mounting bracket 201 is coaxially fitted with a spring 204, and the two ends of the spring 204 are respectively fixedly connected to the corresponding handle 203 and the outer end faces of the vertical parts of the L-shaped mounting bracket 201. The effect of this arrangement is to make the storage box body 3 stuck in the front and rear positions by means of vertical sliding fit. After being positioned between the L-shaped mounting brackets 201, the storage box body 3 can be detachably fixed to the top surface of the operating table 101 by means of the longitudinal sliding cooperation of the limiting rod 205 and the limiting hole 207. At the same time, the limiting rod 205 only needs to be pulled out of the limiting hole 207 to allow the storage box body 3 to slide away from between the front and rear L-shaped mounting brackets 201 in a vertical sliding cooperation manner and be detached from the top surface of the operating table 101. The fixing, assembly and disassembly of the storage box body 3 on the top surface of the operating table 101 are simple and easy to achieve.

[0035] See also Figures 1-4As shown, the bag anti-fall assembly 4 and the quick-release assembly 2 have been optimized as follows. Specifically, with respect to the bag anti-fall assembly 4, the clamping plates 403 are randomly placed between the corresponding clamping slots 402 on both sides of each group in a vertical friction fit manner. The top surfaces of the clamping plates 403 are not lower than the top surface of the storage box 3 and are fixedly installed with pull rings 404 for easy grasping. This arrangement facilitates the adjustment of the spacing between adjacent clamping plates 403 by vertically cooperating with the clamping slots 402 at different positions, thereby enabling the bag anti-falling restriction of pre-prepared food packaging bags of different widths. Optionally, the push-stop plates 408 are rectangular long strips arranged vertically in the longitudinal direction, and the front and rear end surfaces of the push-stop plates 408 are close to the inner surface of the storage box 3 but do not contact it. This arrangement facilitates the push-stop plates 408 to have sufficient length for use, thereby ensuring that pre-prepared food packaging bags of different sizes can be straightened and prevented from falling. Further optionally, the inner end of the adjusting screw 406 is coaxially fixed to the inner ring of the rotary bearing built into the bearing seat 4010, and the bearing seat 4010 is fixed to the side end face corresponding to the push plate 408, so that the adjusting screw 406 and the push plate 408 can be rotatably connected together through the bearing seat 4010.

[0036] More specifically, the locking nut 405 is a hand-tightened knurled nut, and a handle 407 is fixedly mounted on the outer end of the adjusting stud 406 for easy gripping. This arrangement facilitates firstly the locking nut 405 to be directly tightened or loosened by hand, and at the same time, the adjusting stud 406 can be easily twisted by gripping the handle 407. Further, optionally, the storage box body 3 is provided with guide holes 409 in the transverse direction before and after the adjusting stud 406. The guide holes 409 are coaxially inserted with guide rods 401 in a transverse sliding manner, and the inner ends of the guide rods 401 are fixed to the corresponding side end surfaces of the push plate 408. This arrangement facilitates the lateral movement of the push plate 408 by the guide rods 401 sliding along the guide holes 409 when the adjusting stud 406 drives the push plate 408 to move laterally, thereby preventing the push plate 408 from being misaligned as the adjusting stud 406 rotates. Specifically speaking of the quick-release assembly 2, the storage box body 3 is a long rectangular box body vertically in the longitudinal direction, and the bottom surface of the storage box body 3 is in contact with the top surface of the operating table 101, and the four corners of the horizontal part of the L-shaped mounting frame 201 are vertically opened with connecting holes 202. The advantage of this arrangement is that, first, during the vertical sliding of the storage box body 3 along the L-shaped mounting frame 201 in the front and rear positions, when the limiting plug hole 207 slides vertically with the storage box body 3 to be longitudinally coaxial with the limiting plug rod 205, an obvious prompt can be given by the way that the bottom surface of the storage box body 3 is in contact with the top surface of the operating table 101. At the same time, since the horizontal part of the L-shaped mounting frame 201 is opened with the connecting hole 202, the L-shaped mounting frame 201 can be fixed on the top of the operating table 101 by installing screws to the top surface of the operating table 101 through the connecting hole 202.

[0037] The above structure is adopted, specifically in the process of vacuum packaging of pre-prepared food packaging bags, since a storage box 3 is provided on the top surface of the operating table 101 of the vacuum packaging machine body 1, and a bag body anti-falling component 4 is provided in the storage box 3, the pre-prepared food packaging bag can be placed upright in the storage box 3 by means of the push plate 408 and the clamping plate 403 of the bag body anti-falling component 4 from the outside, replacing the operator's manual bag body anti-falling method of the pre-prepared food packaging bag, reducing the operator's workload, and being conducive to improving the vacuum packaging efficiency of the pre-prepared food packaging bag. The vertical cooperation between the card slots 402 and the different positions of the card plates 403 can adjust the distance between the adjacent card plates 403, and then the bag anti-falling restriction can be performed on the pre-prepared food packaging bags of different widths. At the same time, by adjusting the forward and reverse rotation of the studs 406, the distance between the push plate 408 and the inner surface of the storage box body 3 can be adjusted, and then the bag anti-falling restriction can be performed on the pre-prepared food packaging bags of different thicknesses, thereby realizing the bag anti-falling restriction of pre-prepared food packaging bags of different specifications, enriching the general use range of the bag anti-falling component 4, and improving the use flexibility of the bag anti-falling component 4. When the storage box body 3 is assembled and disassembled on the top surface of the operating table 101, since the top surface of the operating table 101 is equipped with quick-release assembly components 2 at the front and rear positions of the storage box body 3, the storage box body 3 is clamped between the L-shaped mounting brackets 201 at the front and rear positions by vertical sliding cooperation, the storage box body 3 can be detachably fixed to the top surface of the operating table 101 by longitudinally sliding cooperation of the limiting plug rod 205 and the limiting plug hole 207. The fixed combination method of the storage box body 3 on the top surface of the operating table 101 is simple and easy to implement, and then it is convenient to quickly fix the storage box body 3. The top surface of the operating table 101 of the vacuum packaging machine body 1 is fixed to prevent the pre-prepared food packaging bags from falling over. When disassembling, it is only necessary to hold the handles 203 at the front and rear positions and pull them outwards. The limit rods 205 are all disengaged from the limit holes 207 by the stretching of the springs 204. Then, the storage box body 3 can be slid away from the L-shaped mounting frames 201 at the front and rear positions in a vertical sliding manner and disassembled from the top surface of the operating table 101. The disassembly method of the storage box body 3 on the top surface of the operating table 101 is simple and easy to implement, and then it is convenient to disassemble the storage box body 3 from the top surface of the operating table 101 for subsequent maintenance and cleaning.
