In order to facilitate the sealing of packaging boxes, automatic and semi-automatic sealing machines are gradually used to seal the packaging boxes, which can save labor costs and improve packaging efficiency. Existing sealing machines usually include conveyor belt groups respectively arranged on both sides, and a movement arranged between the two conveyor belt groups for sealing operations. However, during use, the tape often falls off or moves during use, resulting in the inability to operate the sealing operation normally. The tape needs to be re-adjusted for the sealing operation, resulting in low operating efficiency. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: As shown in the attached Figures 1 to 3 The movement of a carton sealing machine shown in the figure comprises a front baffle 1 and a connected rear baffle 2, wherein a first roller 3, a second roller 4, a cutter assembly 5 and a third roller 8 are sequentially arranged between the front baffle 1 and the rear baffle 2, a movable connecting rod 9 is hingedly arranged between the second roller 4 and the cutter assembly 5, a tape pressing wheel 10 is arranged on one side of the first roller 3 on the front baffle 1, a fixed bracket 11 is elastically connected to one side of the tape pressing wheel 10 (the tape pressing wheel 10 and the tape fixing bracket 11 are connected by a tension spring for adjusting the tension of the tape), an anti-slip base 12 is arranged on the fixed bracket 11, a limit assembly 13 is arranged on the anti-slip base 12, and the limit assembly 13 comprises a plurality of movable panels 14 (specifically 3 to 4 groups) arranged in a ring array, an elastic member 15 and a locking member 16 The locking member 16 (specifically a bolt) passes through the movable panel 14 and is tightened on the anti-slip base 12. The elastic member 15 is sleeved on the locking member 16 and the two ends thereof are respectively pressed against one side of the movable panel 14 and the anti-slip base 12. After being squeezed by the tape, the movable panel 14 shrinks and gives way to the side of the anti-slip base 12, and at the same time presses against the inner circumference of the tape to form a clamping force. During the installation of the tape, the outer circumference of the movable panel 14 is squeezed by the inner circumference. At this time, the movable surface shrinks toward the side of the positioning groove 18 and squeezes the elastic member 15 at the same time. When the tape is installed, the elastic member 15 continuously releases the contraction pressure and acts on the movable panel 14, so that the movable panel 14 can continue to squeeze the tape. The friction flange 26 on the movable panel 14 increases the friction of the tape, which can prevent the tape from falling off and improve the working efficiency.

[0018] As attached Figure 2 As shown, the movable panel 14 is provided with a plurality of through holes 17 (specifically, two are provided), the anti-detachment base 12 is provided with a positioning groove 18 matched with the movable panel 14, and a positioning column 19 (an integrated structure) corresponding to the through hole 17 is arranged in the positioning groove 18, and the tightening member includes a nut 20 and a screw rod 21 (an integrated structure), and a threaded inner wall 23 matched with the screw rod 21 is provided on the positioning column 19, the nut 20 is connected to the screw rod 21 and passes through the through hole 17 and is tightened on the threaded inner wall 23, and the movable panel 14 is limitedly installed by the tightening member, so that the movable panel 14 can be in an up and down movable state in the positioning groove 18, and the tightening member tightened on the positioning column 19 can prevent the movable panel 14 from falling off from one side.

[0019] As attached Figure 3As shown, the movable panel 14 is provided with a limiting groove 24 (corresponding to the number of the positioning posts 19) on one side facing the positioning post 19, and one end of the elastic member 15 (specifically a pressure spring, the number of which corresponds to the positioning post 19) is sleeved on the positioning post 19 and pressed against the bottom of the positioning groove 18, and the other end extends toward one side of the limiting groove 24 and presses against it, thereby limiting and pressing the two ends of the elastic member 15 to prevent deformation of the two ends of the elastic member 15 during the contraction operation.

[0020] As attached Figure 3 As shown, the outer diameter of the limiting groove 24 is larger than the outer diameter of the positioning column 19, and the outer diameter of the through hole 17 is smaller than the outer diameter of the limiting groove 24. The outer diameter of the limiting groove 24 is larger than the outer diameter of the positioning column 19, which facilitates the movable panel 14 to play a role of giving way when the movable panel 14 is retracted, thereby increasing the telescopic distance of the movable panel 14.

[0021] As attached Figure 3 As shown, a clearance opening 25 is opened on one side of the through hole 17, and the nut 20 is installed in the clearance opening 25 and is tightly arranged on the through hole 17 to prevent the nut 20 from scratching the inner wall of the tape.

[0022] As attached Figure 1 As shown, the two ends of the movable panel 14 are respectively provided with a first chamfered surface 27 and a second chamfered surface 28, which facilitates the installation of the adhesive tape and can avoid structural interference between the adhesive tape and the movable panel 14 during installation.

[0023] As attached Figure 1 As shown, some arrays of the movable panel 14 are provided with a plurality of friction flanges 26 , and a gap is provided between two adjacent friction flanges 26 . The plurality of friction flanges 26 are used to increase the friction effect with the inner wall of the tape.
