Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape pasting equipment, and more specifically to an automatic tape pulling and pasting device. Background Art

[0002] In the field of packaging technology, it is often necessary to use tape to seal the packaging film wrapped around the material. For example, when packaging a triangular cake, it is necessary to stick tape on the end surface of the folded packaging bag to prevent the folded packaging bag from being restored, which affects the packaging effect.

[0003] The current structure of the tape applying device is relatively mature and is widely used. For example, the authorization announcement date is July 1, 2022, the authorization announcement number is CN216863185U, and the utility model patent is named "A tape applying device". The utility model patent includes a feeding mechanism, which is used to install a whole roll of tape and lead out the free end of the tape roll; a pulling mechanism, which clamps the free end of the tape roll to pull the tape out to a set length; and an adsorption mechanism, which uses a negative pressure suction nozzle to adsorb on the pulled tape. on a smooth surface; a shearing mechanism, which cuts the pulled tape at a set position to form a tape segment of a specified length, and the tape segment is adsorbed on the negative pressure suction nozzle of the adsorption mechanism, and the adsorption mechanism then adheres the adsorbed tape segment to the junction between the wiring harness and the terminal set at the end of the wiring harness; a pressing mechanism, which presses the tape segment on the outer surface of the wiring harness through a pressing roller, and the adhesive surface of the tape segment is at least partially adhered to the outer surface of the terminal, and the terminal at the end of the wiring harness is pre-positioned at the corresponding end of the wiring harness through the tape segment.

[0004] The above-mentioned tape sticking device is used in the field of cables. The terminal to be crimped is pre-set on the end of the wire harness through the tape sticking device and temporarily positioned by the tape. The adsorption mechanism and the clamping mechanism in the above-mentioned tape sticking device are driven by the first linear module to move synchronously, and the pulling mechanism and the clamping mechanism are driven by the second linear module to move synchronously, that is, the adsorption mechanism and the pulling mechanism are realized by two different sets of linear modules, which has a high cost investment and is not suitable for the packaging of triangular cakes.

[0005] For another example, a utility model patent with the authorization announcement date of April 20, 2021, authorization announcement number of CN213025828U, and name of "Automatic Anti-Folding Mechanism for Wire Winding Machine". This utility model patent includes a tape retaining ring, a tongue pressing mechanism for clamping the tape, a tongue pressing cylinder for driving the tongue pressing mechanism, a tape clamping mechanism for clamping the tape, a tape pulling cylinder for driving the movement of the tape clamping mechanism, a vacuum adsorption mechanism for adsorbing the tape, a vacuum adsorption mechanism cylinder for driving the vacuum adsorption mechanism to move towards the workpiece, a scissor mechanism for cutting the tape, and a scissor cylinder for driving the scissor mechanism to cut. A tape is arranged on the tape retaining ring, and the tongue pressing mechanism and the tape clamping mechanism are sequentially arranged on the movement path of the tape. The vacuum adsorption mechanism and the scissor mechanism are arranged between the tongue pressing mechanism and the tape clamping mechanism.

[0006] In the above-mentioned automatic anti-folding mechanism for wire winding machine, the tape clamping mechanism is driven by the tape pulling cylinder, and the vacuum adsorption mechanism is driven by the vacuum adsorption mechanism cylinder. Its principle is similar to the above-mentioned tape sticking device. Both use two driving mechanisms to drive the tape clamping mechanism and the vacuum adsorption mechanism respectively. The two driving mechanisms need to cooperate with each other, resulting in relatively high control costs and equipment costs. Moreover, it uses a cylinder drive, and the working stroke of the cylinder is fixed. When the length of the tape pulled out changes, a cylinder that meets the tape size needs to be replaced, and its adaptability to changes in the length of the tape pulled out is relatively poor.

[0038] The technical solutions of the present utility model will be further elaborated in detail below in conjunction with the drawings of the specification. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] Refer to the attached drawings of the specification Figure 1 and the attached Figure 2 As shown, this embodiment discloses an automatic tape pulling and pasting device, which includes a feeding mechanism 1 for installing a tape roll 2 and leading out the free end 3 of the tape; a tape pulling mechanism 4 for clamping the free end 3 of the tape roll 2 and pulling out the tape by a set length; a tape pressing mechanism 5 for clamping the tape after the free end 3 of the tape roll 2 is pulled out by a set length; a tape suction cup mechanism 6, the tape suction cup mechanism 6 adsorbs on the smooth surface of the pulled-out tape through a tape suction cup 7; a shearing mechanism 8 for cutting the pulled-out tape at a set position to form a tape section of a specified length; the tape section is adsorbed on the tape suction cup 7 of the tape suction cup mechanism 6, and the tape suction cup mechanism 6 then pastes the adsorbed tape section onto the object to be pasted; it also includes a driving mechanism for driving the tape pulling mechanism 4 and the tape suction cup mechanism 6 to move; the driving mechanism includes a driving component 9 and a transmission component, the transmission component includes a transmission part 10, a first connecting rod 11 and a second connecting rod 12, the driving component 9 drives the transmission part 10 to rotate reciprocally, one end of the first connecting rod 11 is connected to the transmission part 10, and the other end is connected to the tape pulling mechanism 4; one end of the second connecting rod 12 is connected to the transmission part 10, and the other end is connected to the tape suction cup mechanism 6.

[0040] In this embodiment, a driving mechanism drives the tape pulling mechanism 4 and the tape suction cup mechanism 6 to move simultaneously, realizing the movement of the tape pulling mechanism towards the free end 3 of the tape roll 2, and after clamping the free end 3 of the tape roll 2, pulling out the tape by a set length; at the same time, it can realize the movement of the tape suction cup mechanism 6 towards the tape section, and after the tape suction cup 7 adsorbs on the smooth surface of the pulled-out tape, continue to move and paste the tape section onto the object to be pasted; after the pasting is completed, the tape suction cup mechanism 6 retracts and returns to its original position. This reduces the equipment cost and also makes the cooperation between the tape pulling mechanism 4 and the tape suction cup mechanism 6 smoother.

[0041] The working principle of this automatic tape pulling and pasting device is as follows: Assemble the tape roll 2 on the feeding mechanism 1, the feeding mechanism 1 is a rotatable tape chuck, then pull out the free end 3 of the tape, clamp the free end 3 of the tape with the tape pressing mechanism 5, and the free end 3 of the tape needs to protrude about 10 mm from the tape pressing mechanism 5 so that the tape pulling mechanism 4 can clamp the free end 3.

[0042] When this automatic tape pulling and pasting device is started, the driving component 9 is started to drive the transmission part 10 to rotate, and the tape pulling mechanism 4 and the tape suction cup mechanism 6 are respectively driven to move through the first connecting rod 11 and the second connecting rod 12 connected to the transmission part 10.

[0043] When the transmission member 10 rotates clockwise to the tape pulling state, the tape pulling mechanism 4 moves to the free end 3 of the tape clamped by the tape pressing mechanism 5. The tape pulling mechanism 4 clamps the free end 3 of the tape. At this time, the tape pressing mechanism 5 opens, and the transmission member 10 rotates counterclockwise to the tape sucking state. At this time, the tape pulling mechanism 4 moves away from the tape pressing mechanism 5, and the tape suction cup 7 moves towards the tape pulled out by the tape pulling mechanism. The tape suction cup 7 of the tape suction cup mechanism 6 sucks the smooth surface of the tape. The tape pressing mechanism 5 clamps the tape, and the shearing mechanism 8 cuts the pulled-out shorter tape. The tape pulling mechanism 4 releases the tape it clamps. The driving assembly 9 drives the transmission member 10 to continue rotating counterclockwise to the tape pasting state. At this time, the tape suction cup mechanism 6 continues to move with the movement of the transmission member 10, sucking the tape to press against the material so that the tape adheres to the material. The tape suction cup 7 closes, and the driving assembly 9 drives the transmission member 10 to rotate clockwise to start the next cycle. Repeat the above process to complete continuous operation.

[0044] As an example of this embodiment, referring to the attached drawings of the specification Figure 3 and 4 shown, the driving assembly 9 includes a servo motor assembly 14 and a synchronous belt assembly 13. The servo motor assembly 14 is drivingly connected to the transmission member 10 through the synchronous belt assembly 13 to drive the transmission member 10 to rotate reciprocally. In this example, a servo motor assembly 14 (servo motor + reducer) is used as the power source of the driving mechanism (i.e., the driving assembly 9), which can achieve program control. By program setting, the moving stroke of the tape pulling mechanism 4 and the tape suction cup mechanism 6 can be modified to adapt to the change in the tape pulling length.

[0045] As another example of this embodiment, the driving assembly 9 includes a servo motor assembly 14 and a chain drive assembly.

According to the requirements of different tape segment lengths, the positions where the first connecting rod 11 and the second connecting rod 12 are connected to the transmission disk can be adjusted, and the adjustment is more flexible, which is beneficial to the smoothness and coherence of the action coordination between the tape pulling mechanism 4 and the tape suction cup mechanism 6.
