Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a packaging vacuum compressor. Background Art

[0002] Medical protective supplies need to be disinfected and aseptically packaged before leaving the factory to ensure aseptic state during use. Therefore, the packaging vacuum compressor plays an important role in the production process of medical protective supplies. The double-chamber vacuum compressor is a vacuum compression sealing machine with two vacuum chambers. The two vacuum chambers take turns to evacuate and seal, and take turns to pick up and place the products to be packaged, with strong practicability.

[0003] When manufacturers produce and manufacture packaging vacuum compressors, the products leaving the factory are all general-purpose equipment, and there is no specific product positioning mechanism for positioning. However, the nature of users is different, and the products to be vacuum-sealed are different. The most direct difference is the size of the products to be vacuum-sealed. Therefore, when putting the products to be vacuum-sealed, the first step is to put the products and place them preliminarily, and the second step is to adjust the position. It is necessary to ensure that the bag mouths of all the product packaging bags to be vacuum-sealed are close to parallel, and the distance between the bag mouths and the hot sealing head is almost the same. After determination, the pressure bar can be pressed to evacuate and seal, so as to ensure that the sealing position and angle are consistent and the product quality can be guaranteed.

[0004] However, since most of the existing double-chamber vacuum compressors do not have a product positioning mechanism, it is time-consuming and laborious to place and adjust the product position during operation, affecting the efficiency. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides a packaging vacuum compressor, which is used to solve the problem that most of the existing double-chamber vacuum compressors do not have a product positioning mechanism, resulting in time-consuming and laborious placement and adjustment of the product position during operation and affecting the efficiency.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A packaging vacuum compressor includes a chassis main body, a vacuum sealing cover and a movable connecting rod. The chassis main body is movably connected to the vacuum sealing cover through the movable connecting rod. Two hot sealing heads and two pressure bars are respectively installed in the two vacuum chambers of the chassis main body. Guide rails are longitudinally installed on both sides of the inner walls of the two vacuum chambers. The guide rails are located between the two pressure bars. Two baffles parallel to the pressure bars are slidably connected between the two guide rails in the same vacuum chamber. A shear fork is movably installed between the two baffles;

[0008] On the surfaces of two hinge rods on the same side of the articulated shaft of the scissors lift, sleeves are respectively movably sleeved. A connecting rod is hinged between the two sleeves. A push-pull rod is horizontally and fixedly connected to the side surface of the connecting rod. Positioning grooves are equidistantly arranged along the axial direction on the push-pull rod. One end of the push-pull rod away from the articulated shaft is fixedly connected with a push-pull handle. A guide sleeve is movably sleeved on the surface of the push-pull rod. The guide sleeve is fixedly installed in the vacuum chamber, and a ball head spring plunger with a ball head movably inserted into the positioning groove is installed on the guide sleeve.

[0009] Preferably, longitudinal guide sliders are fixedly connected to both ends of the baffle. The guide sliders are slidably connected to the guide rails.

[0010] Preferably, one ends of the two hinge rods of the scissors lift away from the push-pull handle are movably hinged to the baffle. One ends of the two hinge rods of the scissors lift close to the push-pull handle are movably hinged with a transverse slider. The transverse slider is slidably connected in a transverse chute arranged on the baffle.

[0011] Preferably, the connecting rod is perpendicular to the baffle, and the push-pull rod is parallel to the baffle.

[0012] Preferably, the push-pull rod is located on the transverse symmetry axis of the scissors lift, and the distances between the push-pull rod and the two pressure rods are equal.

[0013] Preferably, the push-pull handle is vertically arranged.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] By providing a baffle for adjusting and positioning the position of the product to be vacuumized and sealed, a scissors lift and a push-pull plate for adjusting the position of the baffle, before putting the product to be vacuumized and sealed, the push-pull rod is pulled outwards, so that the scissors lift folds to drive the two baffles to approach each other. When putting the product to be vacuumized and sealed, there is no need to pay special attention to the angle and position. Pushing the push-pull rod can drive the scissors lift to unfold. By driving the two baffles to move away from each other, the angles and positions of multiple products to be vacuumized and sealed can be adjusted respectively, so that the bottoms of the bags of multiple products to be vacuumized and sealed are parallel to the baffle at the same time. Thus, the positions and angles of multiple products to be vacuumized and sealed in the entire vacuum chamber can be adjusted at one time. The operation is simple, convenient and fast, and it is very suitable for popularization and use, solving the problem that most of the existing double-chamber vacuum compressors do not have a product positioning mechanism, resulting in time-consuming and laborious placement and adjustment of the product position during operation and affecting the efficiency.

Both ends of the baffle 7 are fixedly connected with longitudinal guide sliders 16, and the guide sliders 16 are slidably connected with the guide rails 6;

[0023] A scissors lift 8 is movably installed between the two baffles 7. One end of the two hinged rods of the scissors lift 8 away from the push-pull handle 13 is movably hinged to the baffle 7. One end of the two hinged rods of the scissors lift 8 close to the push-pull handle 13 is movably hinged with a horizontal slider 17, and the horizontal slider 17 is slidably connected in a chute horizontally arranged on the baffle 7;

[0024] Sleeve 9s are respectively movably sleeved on the surfaces of the two hinged rods of the scissors lift 8 on the same side of the hinge shaft. A connecting rod 10 is hinged between the two sleeve 9s. The connecting rod 10 is perpendicular to the baffle 7. The push-pull rod 11 is parallel to the baffle 7.
