Description

Technical Field

[0001] This utility model relates to the field of sealing equipment technology, specifically a sealing machine for wet wipe cardboard boxes. Background Technology

[0002] When packing cardboard boxes, they usually need to be sealed. Existing sealing equipment consists of two parts: a tape sealer and tape. Typically, the cardboard box is pressed down manually, and then the tape sealer applies the tape. While this method is simple, operator error can easily cause the tape to wrinkle, affecting the appearance of the packing. This is especially true for larger cardboard boxes; lifting the tape and re-applying it can damage the box. Furthermore, manually handling large quantities of cardboard boxes can cause physical discomfort for the operator.

[0003] However, existing cardboard box sealing machines, as proposed in a published patent (publication number: CN216916532U), include an adhesive tape holder that attaches tape to the top of the box, and a flattening mechanism that smoothly adheres the tape to the box. However, this method only seals the top of the box and cannot secure the lower sides of the top, resulting in a weak seal. Furthermore, it requires manual cutting of the tape. Therefore, this application provides a sealing machine for wet wipe cardboard boxes to solve the problems mentioned in the background. Utility Model Content

[0018] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0019] refer to Figure 1 This is a structural diagram of the mounting frame 1. A conveyor belt 2 is arranged between the mounting frames 1, and a box 21 is placed on the conveyor belt 2. A support frame 3 is fixedly installed at the front end of the mounting frame 1. A lifting mechanism is provided on the support frame 3. The lifting mechanism includes a lifting platform 31 slidably connected to the rear end of the support frame 3. The front end of the lifting platform 31 extends into the interior of the support frame 3. A lead screw 32 is rotatably connected inside the support frame 3. The upper end of the lead screw 32 passes through the top of the support frame 3. A crank handle is fixedly connected to the upper end of the lead screw 32. The lower end of the lead screw 32 passes through the lifting platform 31 and is threadedly connected to the lifting platform 31. An mounting plate 33 is fixedly installed at the rear end of the lifting platform 31. An adhesive tape 34 is fixedly installed at the rear end of the mounting plate 33 through a mounting column. A portion of the adhesive tape 34 extends downward. The lifting platform 31 is raised or lowered by rotating the lead screw 32. The lifting platform 31 drives the mounting plate 33 synchronously when it rises or falls.

[0020] like Figure 2 , Figure 3As shown, a holding mechanism is provided at the rear end of the mounting plate 33. The holding mechanism includes two main rotating frames 4 connected by rotation and are C-shaped. The lower end of the main rotating frame 4 is rotatably connected to a first roller 41. The right end face of the first roller 41 is in contact with the non-adhesive surface of the extended portion of the tape 34. The left end of the main rotating frame 4 is rotatably connected to a support rod 47 via a rotating shaft. The support rod 47 is T-shaped. An inclined plate 42 is fixedly installed on the lower rear end of the mounting plate 33. Guide rods 43 are provided on the front and rear sides of the right end of the inclined plate 42. There are two guide rods 43. The guide rods 43 slide through the inclined plate 42 to the left and are slidably connected. The lower end of each guide rod 43 is fixedly installed with a support spring 44 via a fixing plate. The left end of the support spring 44 is fixedly installed with the inclined plate 42 and is sleeved on the guide rod 43. A cutter head 45 is fixedly installed at the lower end of the guide rod 43. The cutter head 45 is non-contactly connected to the lower end of the first roller 41. Each guide rod 43 is fixedly mounted with a push rod 46, the right end of which is fixedly connected to the main rotating frame 4 via a crossbar. The conveyor belt 2 drives the box 21 to move to the left, and the left end face of the box 21 contacts the right end face of the first roller 41. The first roller 41 sticks the tape 34 to the left end of the box 21. As the box 21 continues to move to the left, the force of the box 21 causes the main rotating frame 4 to rotate clockwise through the first roller 41 until the first roller 41 moves to the top of the box 21 and stops rotating. The first roller 41 rotates on the box 21, pressing the adhesive surface of the tape 34 onto the box 21 while rotating. The upper end of box 21 is sealed. While the main rotating frame 4 rotates clockwise, it pushes the push rod 46 upwards and to the left, and the push rod 46 pushes the guide rod 43 upwards. During the upward and leftward movement of the guide rod 43, the fixed plate and inclined plate 42 compress the support spring 44. Simultaneously, the guide rod 43 drives the cutter head 45 to move synchronously, preventing the cutter head 45 from cutting the box 21 when the first roller 41 rotates at the upper end of the box 21. When the right end of the box 21 separates from the first roller 41, the support spring 44 returns to its original position to the lower right, driving the cutter head 45 through the guide rod 43. The cutter head 45 then cuts the taut tape 34.

[0021] like Figure 1 , Figure 4As shown, a protruding plate 5 is fixedly installed on the rear end of the mounting plate 33. A limiting rod 51 is fixedly installed on the left end of the protruding plate 5. An auxiliary structure is fixedly installed on the left side of the rear end of the mounting plate 33. The auxiliary structure includes a secondary rotating frame 6, which is rotatably connected to the mounting plate 33 via a rotating shaft. The secondary rotating frame 6 is C-shaped and symmetrically distributed with the main rotating frame 4. A second roller 61 is rotatably connected to the lower end of the secondary rotating frame 6. A sleeve rod 62 is provided on the right end of the secondary rotating frame 6. The sleeve rod 62 is T-shaped, and its left end is rotatably connected to the secondary rotating frame 6. The right end of the sleeve rod 62 is hollow. The left end of the sleeve rod 62 is sleeved on the limiting rod 51, and the left end of the limiting rod 51 is slidably connected inside the sleeve rod 62. The lower end of the sleeve rod 62 is rotatably connected to the left end of the support rod 47 via a fixed plate and a rotating shaft. When the main rotating frame 4 rotates clockwise, it pushes the support rod 47 to the left. As the support rod 47 moves to the left, it pushes the sleeve rod 62 to the left and slides on the limit rod 51. Since the upper end of the second roller 61 is rotatably connected to the mounting plate 33, when the sleeve rod 62 moves to the left, it causes the second roller 61 to rotate clockwise with its upper end as the axis. This causes the lower end of the auxiliary rotating frame 6 to rise and roll the tape 34 on the upper end of the housing 21 again. Simultaneously, because the two ends of the guide rod 43 are rotatably connected, and the left end of the sleeve rod 62 is rotatably connected to the auxiliary rotating frame 6, the force is prevented from being lost due to changes in angle during rotation. When the main rotating frame 4 is not in contact with the top of the box 21, because the auxiliary rotating frame 6 is rotatably connected to the upper end of the box 21, the main rotating frame 4 and the auxiliary rotating frame 6 move synchronously, thus preventing the main rotating frame 4 from moving downwards. The auxiliary rotating frame 6 is separated from the upper end of the box 21. The main rotating frame 4 and the auxiliary rotating frame 6 rotate counterclockwise and move downwards, cutting the tape 34 through the cutter head 45. At the same time, the second roller 61 at the lower end of the auxiliary rotating frame 6 sticks the cut tape 34 to the right end of the box 21, thereby sealing the upper end and both sides of the box 21.

[0022] Working principle: The height of the mounting plate 33 is adjusted by the lead screw 32 so that the height of the first roller 41 is lower than the top of the housing 21. The conveyor belt 2 driven by the motor transports the housing 21 to the left. As the housing 21 moves to the left, the first roller 41 pushes the main rotating frame 4 to the left, causing the main rotating frame 4 to rotate clockwise. At the same time, the first roller 41 attaches the extended adhesive tape 34 to the left end of the housing 21. As the main rotating frame 4 rotates clockwise, the first roller 41 attaches the adhesive tape 34 to the upper end of the housing 21. Simultaneously, the main rotating frame 4, while rotating clockwise, pushes the guide rod 43 upward, compressing the spring support spring 44, and the cutter head 45 moves upward synchronously. At the same time, the support rod 47 and the sleeve rod 62 push the auxiliary rotating frame 6, causing it to rotate clockwise synchronously with the main rotating frame 4. When the main rotating frame 4 and the auxiliary rotating frame 6 are simultaneously separated from the housing 21, the support spring 44 resets and moves the cutter head 45, the main rotating frame 4 and the auxiliary rotating frame 6 downward through the guide rod 43. After the cutter head 45 moves downward, it cuts the tape 34. At the same time, the cut tape 34 is pressed tightly against the right end of the housing 21 by the second roller 61.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
