Description

Technical Field

[0001] This utility model belongs to the field of tape application technology, specifically relating to an application mechanism and application equipment. Background Technology

[0002] Cardboard boxes are typically folded during transport. When in use, they need to be unfolded, items placed inside, and the opening sealed with tape. Existing tape-sealing mechanisms usually include a support platform with a tape-sealing notch and tape-sealing rollers within it. The tape is hung on these rollers. By sliding the cardboard box on the support platform, the tape is applied to the opening. A cutting component moves up and down within the tape-sealing notch. When the cardboard box slides a set distance and is detected by a sensor, the sensor transmits a signal to an industrial control computer. The computer then controls a lifting mechanism to raise the cutting component and cut the tape, thus controlling the tape cutting point and ensuring the tape length is appropriate. While this method accurately controls the tape cutting point, it requires sensors, an industrial control computer, and a lifting mechanism, resulting in a complex structure, high failure rate, and poor economic efficiency.

[0003] Therefore, how to avoid making the control of the tape cutting point too complicated is a technical problem that urgently needs to be solved in this field.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0012] In one optional embodiment, the ratio of the distance between the hinge axis of the support rod and the attachment plate to the rotation axis of the attachment plate to the distance between the hinge axis of the support rod and the clamping plate to the rotation axis of the clamping plate is 0.45-0.75.

[0013] In one optional embodiment, a second pin is provided on the side wall of the support plate. The second pin is connected to the clamping support plate through an elastic element, so that the clamping support plate always tends to drive the attachment support plate to stand up, thereby causing the attachment roller to reset and smooth the tape.

[0044] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] See Figures 1 to 8 An adhesive application mechanism is shown, comprising: a support plate 1 with a support wheel 11 on its side wall, the support wheel 11 being adapted to mount adhesive tape 15; an adhesive support plate 2 hinged to the side wall of the support plate 1, an adhesive roller 21 rotatably mounted on the side wall of the adhesive support plate 2, the adhesive tape 15 being hung on the adhesive roller 21; a support platform 3 disposed on the top of the support plate 1 and adapted to support a cardboard box 6, the support platform 3 having an adhesive notch 31, and the adhesive roller 21 initially protruding from the adhesive notch 31, the adhesive roller 21 being adapted to be pressed into the adhesive notch 31 and roll to complete the application of adhesive tape 15 when the cardboard box 6 slides past the adhesive roller 21; and a cutting assembly 4 disposed on the side wall of the support plate 1, the cut of the cutting assembly facing the adhesive notch 31, so that the adhesive tape 15 is applied to the side wall of the support plate 1; and a cutting component 4 disposed on the side wall of the support plate 1, the cut of the cutting component facing the adhesive notch 31, so that the adhesive tape 15 is applied to the side wall of the support plate 1. When the attaching roller 21 is pressed in, the attached tape 15 is cut. The side wall of the support plate 1 is provided with a hinge shaft 12, which is connected to the cutting component 4 to adjust the cutting position of the cutting component, so that the cutting position of the tape 15 is adjustable. In short, the roll of tape 15 is held on the support wheel 11 and wrapped around the guide wheel 55, with its end hanging on the attaching roller. When the cardboard box 6 slides past the attaching roller 21, the tape 15 is attached to the cardboard box 6 by the rotation of the attaching roller 21. At the same time, the attaching roller 21 is pressed into the attaching notch 31, and the uncut tape 15 is pressed down to contact the cutting component 4, thus completing the cutting of the tape 15. The cutting position of the tape 15 can be adjusted by the angle-adjustable cutting component 4, thereby adjusting the length of the tape 15. The structure is simple and reliable.

[0046] In some embodiments, the cutting assembly 4 includes a cutting base plate 41, a cutting support plate 42, and a cutting blade 43; the cutting blade 43 is disposed at the end of the cutting support plate 42, the cutting support plate 42 is disposed on the side wall of the cutting base plate 41, and the side wall of the cutting base plate 41 is connected to the hinge shaft 12; and, the side wall of the supporting plate 1 is provided with an adjusting ring groove 13, the adjusting ring groove 13 is coaxially disposed with the hinge shaft 12, and the adjusting ring groove 13 is fastened to the cutting base plate 41 by bolts to fix the position of the cutting blade 43; in short, the cutting base plate 41 is connected to the hinge shaft 12 so that the cutting assembly 4 is hinged, and the cutting base plate 41 is fastened to the adjusting ring groove 13 by bolts so that the cutting assembly 4 is fixed after the angle is adjusted, and the cutting support plate 42 and the cutting blade 43 are thus disposed on the cutting base plate 41.

[0047] In some embodiments, the cutting support plate 42 is provided with a waist-shaped groove 42a, which is connected to the cutting base plate 41 by bolts; and the waist-shaped groove 42a is arranged perpendicularly to the hinge shaft 12 to adjust the cutting head 43 to move closer to / away from the tape 15; in short, the cutting support plate 42 has a waist-shaped groove perpendicular to the hinge shaft 12 so that the cutting support plate 42 can move closer to / away from the tape 15 so that the tape 15 only contacts the cutting head 43 to cut after the attaching roller is fully pressed into the attaching notch 31.

[0048] In some embodiments, a receiving gap 42b is provided between the cutting support plate 42 and the supporting upright plate 1 to avoid interference between the attaching support plate 2 and the cutting support plate 42 when the attaching support plate 2 rotates; in short, when the attaching roller is pressed into the attaching notch 31, the attaching support plate 2 enters the receiving gap 42b.

[0049] In some embodiments, a clamping assembly 5 is further included, which is disposed on the side wall of the support plate 1. The clamping assembly 5 includes a first clamping plate 51 and a second clamping plate 52. The first clamping plate 51 is hinged and is always clamped to the second clamping plate 52 by an elastic member 56. The adhesive tape 15 passes between the first clamping plate 51 and the second clamping plate 52 and always extends outward. The second clamping plate 52 abuts against the attachment roller 21 in the initial state so that the protruding end of the adhesive tape 15 is hung on the attachment roller 21. In short, the first clamping plate 51 is always clamped to the second clamping plate 52 by the elastic member 56 to clamp the adhesive tape 15, so that after the adhesive tape 15 is cut, a section always remains hanging on the attachment roller, so that when the cardboard box 6 is close to the attachment roller, the exposed adhesive tape 15 can be attached to the cardboard box 6.

[0050] In some embodiments, the clamping assembly 5 further includes a clamping support plate 53, which is hinged to the side wall of the supporting plate 1. The first clamping plate 51 and the second clamping plate 52 are respectively disposed on the side wall of the supporting plate 1. A first pin 53a is provided on the side wall of the clamping support plate 53 to mount an elastic element 56. A support rod 54 is hinged between the clamping support plate 53 and the attaching support plate 2 to form a linkage structure, so that when the attaching roller 21 is pressed in, the clamping assembly 5 rotates accordingly, thereby causing the adhesive tape 15 to be... The cutting component cuts the tape. In short, the first clamping plate 51 and the second clamping plate 52 are set on the clamping support plate 53. A hook 51a is punched out on the first clamping plate 51. The clamping support plate 53 is provided with a first pin 53a to install the elastic element 56. The other end of the elastic element 56 is hung on the hook 51a so that the first clamping plate 51 always clamps the second clamping plate 52. The clamping support plate 53 and the attachment support plate 2 form a linkage structure through the support rod 54, so that the tape 15 can be pressed synchronously by the clamping component 5 towards the cutting component 4 to complete the cutting of the tape 15.

[0051] In some embodiments, the ratio of the distance between the hinge shaft 12 of the support rod 54 and the attachment plate 2 to the rotation axis of the attachment plate 2 and the distance between the hinge shaft 12 of the support rod 54 and the rotation axis of the clamping plate 53 is 0.45-0.75; in short, the distance between the hinge shaft 12 of the support rod 54 and the attachment plate 2 to the rotation axis of the attachment plate 2 (i.e., L1) is smaller than the distance between the hinge shaft 12 of the support rod 54 and the rotation axis of the clamping plate 53 (i.e., L2), so that the clamping plate 53 can rotate through more angles than the attachment plate 2, so that the tape 15 can be stably cut by the cutting assembly 4.

[0052] In some embodiments, a second pin 14 is provided on the side wall of the supporting plate 1. The second pin 14 is connected to the clamping support plate 53 through an elastic member 56, so that the clamping support plate 53 always tends to drive the attaching support plate 2 to stand up, so that the attaching roller 21 resets and smooths the tape 15. In short, by providing the second pin 14 and the elastic member 56, after the paper box 6 slides past the attaching roller, the clamping support plate 53 is driven to reset by the elastic member 56, and at the same time, the clamping support plate 53 drives the attaching support plate 2 to reset.

[0053] Secondly, this disclosure also provides an attachment device, comprising: a base 7 on which a linear conveyor pair 71 is disposed, the linear conveyor pair 71 being adapted to convey a cardboard box 6; the aforementioned attachment mechanism, disposed at the starting point of the linear conveyor pair 71, and the support platform 3 being at the same height as the linear conveyor pair 71; and a first attachment bracket 72, mounted above the attachment mechanism, the attachment bracket being provided with abutment rollers 73 and a pair of belt pairs 74, the abutment rollers 73 being adapted to abut the top of the cardboard box 6, so that... The cardboard box 6 is pressed against the top of the support platform 3. The belt pair 74 is adapted to clamp the cardboard box 6 and convey it to the linear conveyor pair 71 so that the cardboard box 6 can complete the application of the tape 15. In short, a pair of belt pairs 74 are slidably arranged on the first attachment bracket 72 to clamp and slide the cardboard box 6 toward the attachment roller to complete the sealing of the cardboard box 6. In order to prevent the cardboard box 6 from tilting, a retaining roller 73 is provided on the first attachment bracket 72 to press the cardboard box 6 downward. After the cardboard box 6 is sealed, it enters the linear conveyor pair 71 and is conveyed backward.

[0054] In some embodiments, a second attaching bracket 75 is provided at the end of the linear conveyor pair 71, and another attaching mechanism is invertedly provided on the top of the second attaching bracket 75. The attaching mechanism at the end is adapted to press the cardboard box 6 onto the linear conveyor pair 71. Also, another pair of belt pairs 74 are provided at the end of the linear conveyor pair 71. The belt pairs 74 are adapted to clamp the cardboard box 6 and slide the cardboard box 6 past the attaching mechanism located above, so that the top of the cardboard box 6 is covered with tape 15. In short, a second attaching bracket 75 is provided at the end of the linear conveyor pair 71, and another attaching mechanism is inverted on the second attaching bracket 75 to seal the top of the cardboard box 6, achieving same-side sealing of the cardboard box 6. Furthermore, a flipping mechanism 76 is provided on the linear conveyor pair 71 to control the direction of the cardboard box 6, allowing the cardboard box 6 to be sealed diagonally.
