Description

Technical Field

[0001] The present invention relates to the technical field of carton sealing machines, in particular to a semi-automatic carton sealing machine with automatic setting. Background Art

[0002] Carton sealing machine is a commonly used packaging machine, which is mainly used for sealing cartons or paper boxes. It uses BOPP adhesive tape (sealing tape) to seal cartons, and can seal the upper and lower sides of the carton at the same time. It has the characteristics of fast packaging speed, high efficiency and beautiful appearance. Cartons or paper boxes can be divided into three categories according to the sealing form, namely MP cartons, LNK cartons and airplane boxes. The sealing of MP cartons is located on the upper end surface with no gaps on both sides. The sealing of LNK cartons is located on the upper end surface with gaps on both sides. The sealing of airplane boxes is located at the connection between the two sides, and the sealing area is smaller.

[0048] The MP paper box will cause lateral movement during the clamping process. Since the items carried inside the MP paper box have a certain weight, the guide wheel body 403 that plays a supporting role will move with the MP paper box, causing the movable protrusion 405 to move linearly in the movable groove 404, causing the return spring 407 on one side to be compressed and the return spring 407 on the other side to be stretched.

[0049] Then start the screw motor 22 to drive the long screw 23 to rotate, causing the connecting arm 24 to descend along the long screw 23 (the screw nut sleeve 25 and the threads on the long screw 23 interact with each other), thereby driving the entire upper movement 30 to move downward, and using several sets of height measuring wheels 37 to abut against the upper end surface of the MP paper box to lock the height of the pressure seat 35 to ensure that the gluing height of the upper movement 30 is accurate. Then start the conveying motors in the two sets of box conveying seats 10 at the same time, and the rotation of the pulley 12 causes the anti-slip belt 13 to rotate, thereby driving the MP paper box in the clamping position to move in a straight line from left to right. When passing through the upper movement 30, the sealing operation at the opening of the upper end surface of the MP paper box is realized. When the MP paper box of the same size is sealed again, this machine can be used directly. Embodiment 2

[0050] like Figure 1-8 As shown, on the basis of the first embodiment, external brackets 40 are symmetrically installed on both sides of the first movement housing 31, and a second cylinder 50 is horizontally installed in one end of each set of external brackets 40, as shown in FIG. Figure 6 and 7 shown.

[0051] Specifically, a moving rod 51 is movably provided in the second cylinder 50 and extends outward. A connecting portion 52 is provided at the end of the moving rod 51. A connecting column 48 is horizontally welded to the side of the connecting portion 52. Figure 7 shown.

[0052] Furthermore, an extrusion chute 41 is provided through the outer side of the external bracket 40, and the extrusion chute 41 changes from a curve to a horizontal extension from left to right (including a curve track and a horizontal track), and an extrusion block 42 is movably provided outside the extrusion chute 41, and the right end of the extrusion block 42 acts on the edge gap of the LNK paper box, such as Figure 6 shown.

[0053] Among them, the inner side of the extrusion block 42 is horizontally welded with a positioning wheel shaft 43, and a pulley 44 acting on the extrusion chute 41 is installed on the positioning wheel shaft 43. The pulley 44 is stuck on the extrusion chute 41 and rolls. The inner side of the extrusion block 42 is provided with an inner curved groove 45 that matches the trajectory of the extrusion chute 41 at the left position, and the outer surface of the inner curved groove 45 is provided with a step 46, which plays a limiting role. Figure 7 and 8 shown.

[0054] Among them, a driving wheel 47 is movably provided in the inner curved groove 45, and the driving wheel 47 is sleeved on the end of the connecting column 48. When the pulley 44 is in the curved track at the upper position of the extrusion chute 41, the driving wheel 47 is located at the oblique lower end of the inner curved groove 45. At this time, the extrusion block 42 is slightly higher than the height of the gap at the edge of the LNK paper box. In the process of the moving rod 51 driving the extrusion block 42 to return, since the connecting column 48 moves in the oblique downward direction of the inner curved groove 45 during the horizontal movement, the reaction force is used to push the pulley 44 on the extrusion block 42 to just enter the curved track, as shown in FIG. Figure 7 and 8 shown.

[0055] In this embodiment, the LNK paper box needs to be measured in height according to the steps of Example 1 when it is used for the first time. Then, when the two sets of anti-slip belts 13 drive the LNK paper box to move linearly from left to right and pass through the upper movement 30, the sealing operation at the opening of the upper end surface of the LNK paper box is realized. At the same time, due to the existence of gaps on the left and right sides of the upper end surface of the LNK paper box, the gap on the right side can be directly sealed with tape through the squeezing gap action of the No. 1 front pressure wheel 32, but the gap on the left side needs to be started by starting the second cylinder 50, and the moving rod 51 extends outward. Through the traction action of the connecting column 48, the squeezing block 42 starts to move, and the pulley 44 comes down from the upper curved track position of the squeezing chute 41, and moves in the horizontal track position of the squeezing chute 41. During the movement, the right end of the squeezing block 42 is directly used to squeeze the gap on the left side of the LNK paper box to ensure that the gap on the left side is closed, which is convenient for the tape sealing of the upper movement 30.

[0058] Furthermore, a pre-pressing sheet 67 acting on the lower end surface of the aircraft box is fixedly installed on the side of the second front pressure wheel 63. The pre-pressing sheet 67 is higher than the height of the second front pressure wheel 63 and can move with the second front pressure wheel 63. Fig. 9 shown.

[0059] In this embodiment, the L-shaped movement 61 is first placed into the installation groove 60, and then the aircraft box is directly clamped by two sets of anti-skid belts 13 without measuring the height. The two sets of anti-skid belts 13 drive the aircraft box to move linearly from left to right. When passing through the L-shaped movement 61, the pre-pressing plate 67 first interacts with the aircraft box, causing the pre-pressing plate 67 to flip (so that the time and position of the contact between the No. 2 front pressure wheel 63 and the aircraft box are delayed), so that the No. 2 front pressure wheel 63 directly contacts the right position of the lower end surface of the aircraft box, and drags the tape to glue, and then cooperates with the pressing effect of the No. 2 rear pressure wheel 66 to achieve the sealing operation at the L-shaped corner opening of the aircraft box.

During one cycle of motion, the crank 77 uses the driving column 78 to move in the waist groove 81, and the two interact with each other, firstly causing the displacement seat 80 to move linearly to the right in the displacement limit groove, and using the push rod 82 to extend out of the guide port 91, The contact surface 84 of the inverted L-shaped pushing head 83 first contacts the edge of the paper box, and then pushes the paper box to the right, where it will contact one of the sets of curved guide plates 6 to correct the deviation of the paper box.

The outer cylindrical surface of the lifting column 103 is evenly welded with a plurality of spring rods 111 passing through the buffer waist holes 110 .
