Automatic bag-opening upright heat-sealing device

Abstract

The utility model provides an automatic bag opening upright heat sealing device which comprises a machine frame, a conveying belt, a bag opening mechanism, a canning mechanism, a heat sealing mechanism, a supporting mechanism and a guiding mechanism. During use, a packaging bag can be correspondingly inserted into the first vertical crack, the second vertical crack and the horizontal crack, then when the packaging bag moves to the bag opening mechanism, an extrusion plate driven by a horizontal air cylinder extrudes the packaging bag to open the packaging bag, then a vertical air cylinder moves downwards, air is blown to the packaging bag through an air nozzle, and therefore the packaging bag is further opened; and subsequent filling is facilitated. Due to extrusion of an extrusion plate, the edge of a packaging bag originally clamped in a second vertical crack is separated from the second vertical crack, stability of the packaging bag is not facilitated, and due to the arrangement of a guide rod, a movable clamp can be gradually close to the packaging bag in the subsequent movement process till the edge of the packaging bag is clamped in the second vertical crack again; therefore, the stability in the subsequent filling and heat sealing processes is ensured.

[0029] A plurality of support mechanisms 6 for supporting packaging bags are provided at equal intervals on the surface of the conveyor belt 2. The support mechanism 6 includes a support seat 61, a fixed clamp 62 and a movable clamp 63. The support seat 61 is in an elongated shape and is arranged perpendicular to the movement direction of the conveyor belt 2. The fixed clamp 62 is fixed at one end of the support seat 61, and the movable clamp 63 is slidably arranged at the other end of the support seat 61. The opposite sides of the fixed clamp 62 and the movable clamp 63 are respectively provided with a first vertical slit 621 and a second vertical slit 631. The upper surface of the support seat 61 is provided with a horizontal slit 611 facing the first vertical slit 621 and the second vertical slit 631.

[0030] The guide mechanism 7 is arranged on one side of the movable clamp 63, and is used to push and guide the movable clamp 63, and the guide mechanism 7 is adjacent to the support mechanism 6 and penetrates the canning mechanism 4 and the heat sealing mechanism 5; the guide mechanism 7 includes a guide rod 71 and an adjustment frame, the guide rod 71 is installed on the outer side of the movable clamp 63 through the adjustment frame, and the guide rod 71 is arranged parallel to the moving direction of the conveyor belt 2; the guide rod 71 includes an arc segment 712 and a straight segment 711 connected in sequence along the moving direction of the conveyor belt 2, and the distance between the guide rod 71 and the fixed clamp 62 from the arc segment 712 to the straight segment 711 first gradually decreases and then remains unchanged;

[0031] The bag-supporting mechanism 3 includes a first bracket 31, a horizontal cylinder 32, an extrusion plate 33, a second bracket 34, a vertical cylinder 35, a mounting frame 36 and an air nozzle 37; the first bracket 31 is arranged on a side where the movable clamp 63 is arranged, and a horizontal cylinder 32 is arranged on the first bracket 31, and the end of the telescopic rod of the horizontal cylinder 32 is connected to the extrusion plate 33; the second bracket 34 is arranged opposite to the first bracket 31, and a vertical cylinder 35 is arranged on the second bracket 34, and the lower end of the telescopic rod of the vertical cylinder 35 is connected to the mounting frame 36, and a plurality of air nozzles 37 are arranged on the mounting frame 36, and the distance between two adjacent air nozzles 37 is equal to the distance between two adjacent support mechanisms 6.

[0032] Exemplarily, the upper surface of one end of the support seat 61 where the movable clamp 63 is disposed is provided with a groove 612, a slider 614 is slidably provided in the groove 612, and a spring 613 is also connected between the slider 614 and the inner wall of the groove 612; the top of the groove 612 is covered with a removable cover plate 616, and the cover plate 616 is provided with a slit 617 connected to the horizontal slit 611; the top of the slider 614 is also connected to a connecting strip 615 that can pass through the slit 617, and the connecting strip 615 is fixedly connected to the movable clamp 63.

[0037] More specifically, there are two air nozzles 37 , corresponding to two supporting mechanisms 6 respectively.

[0038] The working principle of the device is as follows: when in use, the packaging bag can be inserted into the first vertical slit, the second vertical slit and the horizontal slit respectively, which supports the packaging bag; then when the packaging bag moves to the bag-supporting mechanism, the squeezing plate of the horizontal cylinder squeezes the packaging bag to make it open, and then the vertical cylinder moves down and blows air into the packaging bag through the air nozzle, thereby further propping up the packaging bag for subsequent filling. Due to the squeezing of the squeezing plate, the edge of the packaging bag originally clamped in the second vertical slit is separated from the second vertical slit, which is not conducive to the stability of the packaging bag. The setting of the guide rod can make the movable clamp gradually approach the packaging bag in the subsequent movement process until the edge of the packaging bag is stuck in the second vertical slit again, thereby ensuring stability in the subsequent filling and heat sealing process.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
