[0002] At present, most of the woven bags on the market are sealed by sewing, which cannot achieve a sealing effect. In order to solve this problem, the market achieves a sealing effect by sticking tape on the outside of the seam line. However, the external tape on the market is currently achieved by sticking a hot-melt tape substrate on the outside of the seam line. The hot-melt tape substrate is a kraft paper tape, and the seam line is sealed by heating and melting the surface adhesive of the paper tape. In outdoor or humid environments, the sealing strip is easily melted after contacting water, resulting in failure to seal.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0022] See also Figure 1-5 The figure shows a packaging machine for sealing with folding and sewing transparent tape. The packaging machine includes a frame 1, on which are sequentially arranged a packaging bag front end introduction mechanism 2, a packaging bag folding mechanism 3, a packaging bag sewing mechanism 4 and a control part 7. The packaging bag front end introduction mechanism 2, the packaging bag folding mechanism 3, the packaging bag sewing mechanism 4 and the control part 7 are prior arts, and these parts are not related to the technical problem to be solved by this application, so they are not elaborated in detail in this embodiment. The packaging machine also includes a tape part 5, which is provided at the end of the packaging bag sewing mechanism 4. The tape part 5 includes a tape conveying mechanism 51 and a tape forming side sticking mechanism 52. There are two tape conveying mechanisms 51, which respectively stick the conveyed tape 6 to the seam lines on both sides of the packaging bag. The tape forming side sticking mechanism 52 includes a mounting plate 521, a tape guide mechanism 522 installed on the mounting plate 521, and a tape cutting mechanism 523. The tape 6 is led out from the tape conveying mechanism 51, and then passes through the tape guide mechanism 522 to enter the sticking position and stick to the packaging bag. After the sticking is completed, the tape 6 is cut by the tape cutting mechanism 523 to complete the tape side sticking.

[0023] To facilitate the introduction of the adhesive tape and / or packaging bag into the taping position, the adhesive tape forming side-taping mechanism 52 in this embodiment further includes an active connecting rod assembly 524 for pressing the adhesive tape 6 against the packaging bag. The adhesive tape guide mechanism 522 of the adhesive tape forming side-taping mechanism 52 includes a fixed rubber wheel 5221 and a movable rubber wheel 5222, wherein the movable rubber wheel 5222 is connected to the active connecting rod assembly 524, and the two rubber wheels are driven to move away from or closer to each other by the active connecting rod assembly 524. When the two rubber wheels are apart, the introduction of the adhesive tape and packaging bag can be facilitated. When taping is applied, the packaging bag passes between the two rubber wheels, and the adhesive tape also passes between the two rubber wheels. When the two rubber wheels are close to each other, the adhesive tape on both sides of the packaging bag is pressed against the packaging bag to ensure that the adhesive tape can fully adhere to the seam line of the packaging bag, reduce or avoid problems such as wrinkles or loose fit between the adhesive tape and the packaging bag, and ensure a good sealing effect.

[0024] The active connecting rod assembly 524 described in this embodiment includes an active connecting rod 5241, an active connecting rod seat 5242, a movable rubber wheel 5222 installed on the active connecting rod 5241 and moving together with the active connecting rod 5241, and a connecting rod cylinder 5243 that drives the active connecting rod 5241 to move. The movable rubber wheel 5222 is coaxially provided with a driven wheel 5244, and a driving wheel 5245 that is transmission-connected to the driven wheel 5244 is installed on the mounting plate 521. The driving wheel 5245 is connected to a driving source, which is a motor. The mounting plate 521 is also provided with a leveling mechanism 525 for leveling the bag opening of the packaging bag. The leveling mechanism 525 is provided on both sides of the packaging bag running channel, and includes a fixed leveling device and a movable leveling device, wherein the fixed leveling device includes a fixed leveling wheel 5251 mounted on the mounting plate, and the fixed leveling wheel 5251 is rotatably connected to the mounting plate 521, and the movable leveling device includes a leveling link 5252 movably mounted on the mounting plate 521, and a movable leveling wheel 5253 mounted on the leveling link 5252 and moving together with the leveling link 5252, and the leveling link 5252 is mounted on the mounting plate 521 through a leveling link shaft seat 5254, wherein the leveling link 5252 is connected to the active link 5241 through a connecting plate 526, so that when the active link 5241 moves, it can drive the leveling link 5252 to move together. Tape guides 522 are installed on both sides of the bag passageway. These guides include several steering wheels 5223 and transition wheels 5224, arranged at different angles. When the bag opening is sensed to enter the rubber wheel, the connecting rod cylinder 5243 of the active connecting rod assembly drives the movable rubber wheel 5222 and the movable leveling wheel 5253 toward the fixed rubber wheel 5221, closing them. The movable leveling wheel 5253 and the fixed leveling wheel 5251 level the bag opening, and the rubber wheels feed the transparent tape to the bag opening, securing it. The tape cutting mechanism then cuts the tape, completing the process.

[0025] The tape conveying mechanism 51 in this embodiment includes a tape reel 511, a tape reel 512, and a tape roller 513. The tape reels 512 of the two tape conveying mechanisms 51 are fixed to a mounting plate 521. The tape reel 511 passes through the tape roller 513 and the tape reel 512 and is connected to a locking nut 514 at its end, securing the tape roller 513 to one side of the tape reel 512. The tape roll 515 is sleeved onto the tape roller 513. A plurality of locking blocks 516 are arranged in a circular array around the tape roller 513, and the locking blocks 516 collectively elastically support the tape roll 515. In this embodiment, the tape roller 513 is axially provided with a retaining groove 5131. The locking blocks 516 are retained in this groove and can move radially therein. A spring 517 is provided between the locking block 516 and the inner wall of the groove to push the locking block outward. The locking block 516 is a T-shaped structure with a narrow mouth and a T-shaped structure. After the locking block 516 is inserted into the slot, it can move radially in the slot. After the spring is installed on the back of the locking block 516, it can push the locking block so that the three locking blocks elastically support the tape roll 515 to fix the tape roll 515 and the locking block 516. A compression spring is connected to the outer surface of the tape reel, one end of the compression spring abuts on the tape roller, and the other end abuts on the locking nut. The pressure and friction of the compression spring generate damping to act as a brake. In this way, after the tape roll 515 is put on the tape roller 513, the tape roller will not rotate without external force. When the external force pulls the tape to overcome the damping force of the compression spring, the tape roll rotates.

[0026] The tape cutting mechanism 523 described in this embodiment includes a cutter 5231, a cutter mounting seat 5232, a tape cutting cylinder 5233 for driving the cutter, and a cutter baffle 5234, wherein the cutter baffle 5234 is provided with a socket 52341 for inserting the cutter, and the tape passes between the cutter 5231 and the cutter baffle 5234. The tape cutting cylinder 5233 drives the cutter mounting seat 5232 to move as a whole toward the side of the cutter baffle 5234 to complete the tape cutting. In this embodiment, a slide rail 5236 is fixed on the cutter mounting seat 5232, and it also includes a slider seat 5235 fixed on the mounting plate 521. A slider 5237 is fixed on the slider seat 5235. The slide rail 5236 can move relative to the slider 5237. When the cutting cylinder 5233 drives the cutter mounting seat 5232 to move, the slide rail 5236 slides on the slider 5237. In this embodiment, one end of the cutting cylinder 5233 is mounted on the mounting plate 521.

[0027] In this embodiment, a first pressing member 5238 and a second pressing member 5239 are respectively provided on the cutter mounting base 5232 on the front and rear sides of the cutter 5231. When cutting the tape, both the first and second pressing members elastically press against the sides of the cutter baffle to compress the tape. The arrangement of these two pressing members ensures that the tape does not shift forward or backward with the cutter during cutting. In this embodiment, the first pressing member is a rubber-surfaced pressure wheel, and the second pressing member is a rubber-surfaced pressure plate.
