Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a semi-automatic device for vacuum packaging of pressed salted duck. Background Art

[0002] After the production and processing of pressed salted duck is completed, it needs to be packaged and then sold externally. When packaging, in order to extend the shelf life of the pressed salted duck, generally a vacuum packaging device is used to package the pressed salted duck in a relatively vacuum environment to ensure that the pressed salted duck has a sufficient shelf life and is convenient for transportation.

[0003] A Chinese patent with the publication number CN210175210U discloses a vacuum packaging device, which includes an operating table. A cavity communicating with the outside is arranged inside the operating table, and a vacuum pump is arranged in the cavity; a cushion block arranged along the width direction of the operating table is tightly welded on the surface of the operating table; a vertically arranged support plate is also tightly welded on the operating table. A horizontally arranged top plate is tightly welded on the front side of the support plate. The top plate is located above the cushion block, and a packaging sealing device is arranged on the top plate. The packaging sealing device includes a hydraulic cylinder arranged on the bottom surface of the top plate, and a heat sealing knife is tightly welded on the bottom surface of the fixing plate. The utility model saves time and effort, is simple and fast to operate, reduces the workload of staff, and improves the packaging efficiency.

[0004] In the above-mentioned prior art solution, the air in the packaging bag is sucked away by a suction plate, and then the opening of the packaging bag is placed in the cushion block. The hydraulic cylinder is pushed to move the hot air knife downward and press it on the surface of the packaging bag to perform the packaging and sealing operation. However, in the actual use process, in order to facilitate the placement of food, only one opening is left on the packaging bag. When performing the air extraction operation, the packaging bag needs to be bent so that the opening of the packaging bag wraps the suction plate, and then the packaging bag is taken out and placed on the cushion block, so that the packaging sealing device seals the packaging bag. However, during the movement of the packaging bag, external air easily flows back into the packaging bag, making the inside of the packaging bag not completely in a vacuum state. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a semi-automatic device for vacuum packaging of pressed salted duck. The air in the packaging bag is pumped away by an air extraction pump, and the heating rod rotates around the fixing plate through a linkage rod. Therefore, the side wall of the heating rod will fit with the side wall of the packaging bag, and the heating rod generates heat to heat the side wall of the packaging bag. The opening of the packaging bag is softened by heat and then adhered together to complete the sealing of the packaging bag, avoiding the situation that external air flows back into the inside of the packaging bag.

[0006] The technical solution for achieving the purpose of the present utility model is as follows: A semi-automatic device for vacuum packaging pressed ducks, including a base, on the side wall of the base, a support frame is fixedly installed, on the top wall surface of the support frame, a control device is fixedly installed, at the bottom of the control device, an air extraction assembly is provided, the air extraction assembly includes an air extraction pump arranged on the top of the base, on the bottom wall surface of the air extraction pump, a positioning rod is fixedly installed, on the bottom wall surface of the positioning rod, an air extraction plate is fixedly installed, outside the air extraction pump, a sealing assembly is provided, the sealing assembly includes a positioning plate fixedly installed on the top wall surface of the air extraction pump, the positioning plate is fixedly installed on the inner top wall surface of the control device, outside the air extraction pump, two heating rods are provided at the front and rear ends of the air extraction plate, on the side walls of the two heating rods, wires are electrically connected, on the top wall surfaces of the two heating rods, linkage rods distributed in a mirror image are fixedly installed, on the front and rear side walls of the positioning rod, two fixing plates are fixedly installed respectively, and the closer ends of the two linkage rods are respectively rotatably installed on the side walls of the closer fixing plates.

[0007] In some embodiments, the bottom end of the air extraction plate is trapezoidal, and the air extraction plate is communicated with the air extraction pump.

[0008] In some embodiments, on the side walls of the two linkage rods, movable grooves are respectively opened, on the front and rear side walls of the positioning plate, grooves are respectively opened, and fixed rods are arranged inside the two grooves on the positioning plate and the two movable grooves.

[0009] In some embodiments, on the side wall of the fixed rod, a fixed rotating shaft is fixedly installed, and the fixed rotating shaft is rotatably installed inside the closer side wall.

[0010] In some embodiments, on the closer side walls of the two fixed rods on the same side, adjusting bolts are threadedly connected.

[0011] In some embodiments, on the top wall surface of the base, two limiting strips distributed in a mirror image are fixedly installed, and the gap between the two limiting strips is aligned with the air extraction plate.

[0012] Compared with the prior art, the present utility model has the following remarkable advantages:

[0013] Firstly: In the present utility model, the air in the packaging bag is pumped away by the air extraction pump, and the heating rods rotate around the fixing plates through the linkage rods, so that the side walls of the heating rods will be attached to the side walls of the packaging bag. By controlling the control device to make the heating rods start to work, the heating rods generate heat to heat the side walls of the packaging bag, and the opening of the packaging bag is softened by heat and then adhered together to complete the sealing of the packaging bag, avoiding the situation that external air flows back into the interior of the packaging bag.

[0014] Second: In the present utility model, two fixing rods on the same side are connected together by adjusting bolts. When the air pump evacuates the air in the packaging bag, the air pump will extend downward. At this time, the packaging bag shrinks because the internal air is sucked away, enabling the air pump to more fully suck the air in the packaging bag. The positioning rod moves downward together with the air pump, and thus the two heating rods will rotate around the fixed plate and move closer to the center. When the air in the packaging bag is completely sucked out, the heating rods just fit against the side wall of the packaging bag, facilitating the sealing of the packaging bag.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a semi-automatic device for vacuum packaging of pressed duck through improvement. The technical solution of the present utility model is:

[0023] As Figure 1 - Figure 3As shown in the figure, a semi-automatic device for vacuum packaging salted ducks includes a base 1. A support frame 2 is fixedly installed on the side wall of the base 1. A control device 3 is fixedly installed on the top wall surface of the support frame 2. An air extraction assembly 5 is arranged at the bottom of the control device 3. The air extraction assembly 5 includes an air extraction pump 51 arranged on the top of the base 1. The air extraction pump 51 is electrically connected to the control device 3. A positioning rod 52 is fixedly installed on the bottom wall surface of the air extraction pump 51. A suction plate 53 is fixedly installed on the bottom wall surface of the positioning rod 52. The bottom end of the suction plate 53 is trapezoidal. The suction plate 53 is communicated with the air extraction pump 51. By setting the bottom end of the suction plate 53 to be trapezoidal, it is convenient to put the suction plate 53 into the inside of the packaging bag through the opening end of the packaging bag, and make the inner side wall of the packaging bag closely fit with the side wall of the suction plate 53, so that the air extraction pump 51 can suck the air inside the packaging bag when working. A sealing assembly 6 is arranged outside the air extraction pump 51. The sealing assembly 6 includes a positioning plate 66 fixedly installed on the top wall surface of the air extraction pump 51. The positioning plate 66 is fixedly installed on the inner top wall surface of the control device 3. Two heating rods 61 are arranged at the front and rear ends of the suction plate 53 outside the air extraction pump 51. Electric wires 62 are electrically connected to the side walls of the two heating rods 61. The electric wires 62 are electrically connected to the control device 3. Mirror-image distributed linkage rods 64 are fixedly installed on the top wall surfaces of the two heating rods 61. Two fixing plates 63 are fixedly installed on the front and rear side walls of the positioning rod 52. The adjacent ends of the two linkage rods 64 are respectively rotatably installed on the side walls of the adjacent fixing plates 63. By the air extraction pump 51 sucking the air in the packaging bag, the heating rods 61 rotate around the fixing plates 63 through the linkage rods 64, so that the side walls of the heating rods 61 will fit with the side walls of the packaging bag. By controlling the control device 3 to make the heating rods 61 start to work, the heating rods 61 generate heat to heat the side walls of the packaging bag, and the opening of the packaging bag is heated and softened and then adhered together to complete the sealing of the packaging bag, achieving the effect of improving the packaging efficiency.

[0024] As Figure 1 shown, in an embodiment, in order to ensure the stable position of the packaging bag, two mirror-image distributed limiting strips 4 are fixedly installed on the top wall surface of the base 1. The gap between the two limiting strips 4 is aligned with the suction plate 53. By placing the bottom end of the packaging bag to be packaged between the two limiting strips 4, the two limiting strips 4 clamp the bottom end of the packaging bag to ensure the stable position of the packaging bag and avoid the situation of packaging failure caused by the shaking of the packaging bag during the encapsulation process.

[0025] As Figure 3As shown, in one embodiment, in order to improve the encapsulation speed, movable slots 65 are provided on the side walls of both of the two linkage rods 64, grooves are provided on the front and rear side walls of the positioning plate 66, fixing rods 67 are provided inside the two grooves on the positioning plate 66 and the two movable slots 65, fixing rotating shafts 69 are fixedly installed on the side walls of the fixing rods 67, and the fixing rotating shafts 69 are rotatably installed inside the adjacent side walls. Adjusting bolts 68 are threadedly connected to the adjacent side walls of the two fixing rods 67 on the same side; the two fixing rods 67 on the same side are connected together by the adjusting bolts 68. When the air pump 51 pumps out the air in the packaging bag, the air pump 51 will extend downward. At this time, the packaging bag shrinks because the air inside is sucked away, enabling the air pump 51 to suck out the air in the packaging bag more fully. The positioning rod 52 moves downward together with the air pump 51, and thus the two heating rods 61 will rotate around the fixing plate 63 and move closer to the center. When the air in the packaging bag is completely sucked out, the heating rods 61 just fit against the side wall of the packaging bag, facilitating the completion of the encapsulation of the packaging bag. For packaging bags of different sizes, the adjusting bolts 68 can be rotated to adjust the distance between the two fixing rods 67 on the same side, adjust the movement range of the heating rods 61, improve the applicable range of the heating rods 61, and avoid the situation where the movement range of the heating rods 61 is too large or too small, which affects the encapsulation.

[0026] The specific working method is as follows: The air pump 51 pumps out the air in the packaging bag, and the heating rods 61 rotate around the fixing plate 63 through the linkage rods 64, so that the side walls of the heating rods 61 will fit against the side wall of the packaging bag. The control device 3 controls the heating rods 61 to start working, causing the heating rods 61 to generate heat and heat the side wall of the packaging bag. The opening of the packaging bag is heated and softened, and then adhered together to complete the sealing of the packaging bag, achieving the effect of improving the packaging efficiency; the two fixing rods 67 on the same side are connected together by the adjusting bolts 68. When the air pump 51 pumps out the air in the packaging bag, the air pump 51 will extend downward. At this time, the packaging bag shrinks because the air inside is sucked away, enabling the air pump 51 to suck out the air in the packaging bag more fully. The positioning rod 52 moves downward together with the air pump 51, and thus the two heating rods 61 will rotate around the fixing plate 63 and move closer to the center. When the air in the packaging bag is completely sucked out, the heating rods 61 just fit against the side wall of the packaging bag, facilitating the completion of the encapsulation of the packaging bag. For packaging bags of different sizes, the adjusting bolts 68 can be rotated to adjust the distance between the two fixing rods 67 on the same side, adjust the movement range of the heating rods 61, improve the applicable range of the heating rods 61, and avoid the situation where the movement range of the heating rods 61 is too large or too small, which affects the encapsulation.

[0027] The technical means disclosed by the solution of the present utility model are not limited to those disclosed by the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered by the present utility model are common general knowledge in the art.
