Description

Technical Field

[0001] The present invention relates to the technical field of tape sticking equipment, and in particular to a material tape feeding mechanism of a tape sticking machine. Background Art

[0002] Carton-packaged products, barreled products, and purified water packaged with heat shrink film are large daily necessities that are troublesome and laborious to carry when in use. In the prior art, a solution of adding a plastic pull ring at the bottle mouth is designed for barreled products. This solution is costly and the plastic pull ring itself increases pollution. Therefore, designing a degradable handle on these packages has become an effective and environmentally friendly solution. How to design an automated device that improves these difficult-to-carry product packages to facilitate lifting and carrying is the problem that the inventor wants to solve. It is very important to transport the handle roll because the tension problem needs to be considered during the transportation of the handle roll. Summary of the invention

[0003] In view of the deficiencies in the prior art, the main purpose of the present invention is to provide a feeding structure of a tape attaching machine that can buffer the material tape.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a material tape feeding mechanism of a tape sticking machine, comprising a fixed frame, on which a first tape loosening mechanism, a transmission mechanism and a second tape loosening mechanism are arranged, the first tape loosening mechanism comprises a first linear fixed tension roller group and a first movable tension roller group, an angle is formed between the first fixed tension roller group and the first movable tension roller group, the first fixed tension roller group and the first movable tension roller group both comprise a plurality of tension rollers, the first movable tension roller group comprises a first movable plate and a first power assembly capable of driving the first movable plate to move, a plurality of tension rollers are arranged on the first movable plate, the first power assembly comprises a rotating shaft arranged on the fixed frame, one end of the rotating shaft is connected to the end of the first movable plate, the other end of the rotating shaft is connected to a connecting rod capable of driving the rotating shaft to rotate, the rotating shaft is connected to a first cylinder capable of driving the connecting rod to rotate; the transmission mechanism comprises a motor, a transmission roller connected to the motor and a first cylinder arranged on the The transmission roller is below the transmission roller and contacts with the transmission roller; the second belt loosening mechanism includes a linear second fixed tension roller group and a second movable tension roller group, an angle is formed between the second fixed tension roller group and the second movable tension roller group, the second fixed tension roller group and the second movable tension roller group each include a plurality of tension rollers, the second movable tension roller group includes a second movable plate and a second power assembly capable of driving the second movable plate to move, a plurality of tension rollers are arranged on the second movable plate, the second power assembly includes a rotating shaft arranged on a fixed frame, one end of the rotating shaft is connected to the end of the second movable plate, the other end of the rotating shaft is connected to a connecting rod capable of driving the rotating shaft to rotate, the rotating shaft is connected to a second cylinder capable of driving the connecting rod to rotate, the material belt crosses around the tension rollers on the first fixed tension roller group and the first movable tension roller group and then enters between the transmission roller and the transmission roller, and then crosses around the tension rollers on the second fixed tension roller group and the second movable tension roller group and then leaves.

[0005] Preferably, a limiting column capable of blocking the connecting rod is arranged above the rotating shaft.

[0006] Preferably, a positioning bracket is provided below the fixing bracket, and a positioning block through which the feeding belt passes is provided on the positioning bracket.

[0007] Preferably, a fixing plate is provided on the fixing frame.

[0008] Compared with the prior art, the present invention has the following advantages: the material belt first enters from the first belt loosening mechanism, then enters the transmission mechanism and the second belt loosening mechanism, and finally enters the tape taping part. Since the tape taping part will generate tension on the material belt during tape taping, the second belt loosening mechanism is set to buffer the tension on the material belt. When tape taping is not required normally, the angle between the second movable tension roller group and the second fixed tension roller group is the largest, and the material belt is taut between the second movable tension roller group and the second fixed tension roller group. If the tape taping part needs to taped, the material belt will be pulled. At this time, the second cylinder is actuated, the piston rod of the second cylinder drives the connecting rod to rotate, the connecting rod drives the rotating shaft to rotate, and the rotating shaft drives the second movable plate toward the second fixed plate. The fixed tension roller group moves, and the material belt between the second belt loosening mechanism is loosened. In this way, when the tape part pulls the material belt, the tension of the material belt will not be very large, and the material belt will be pulled calmly. After the material belt is pulled, the transmission mechanism starts to move. The function of the first belt loosening mechanism is to temporarily store the material belt. When the material belt of the second belt loosening mechanism is pulled, the transmission mechanism needs to replenish the material belt. The motor drives the transmission roller to rotate. The material belt between the transmission roller and the transfer roller will be continuously pulled to the second belt loosening mechanism under the action of friction. At this time, the second movable cylinder drives the second movable tension roller group to reset. The action and principle of the first belt loosening mechanism are the same as those of the second belt loosening mechanism. The first belt loosening mechanism is to buffer the pulling force of the transmission mechanism. The first cylinder and the second cylinder are both fixed to the fixed frame by pins, so that the direction of the piston rod can be changed during the movement, so that the connecting rod can rotate.

The material belt crosses around the tension roller 7 on the first fixed tension roller group 5 and the first movable tension roller group 6, and then enters between the transmission roller 13 and the transfer roller 14, and then crosses around the tension roller 7 on the second fixed tension roller group 15 and the second movable tension roller group 16 before leaving.

[0014] Preferably, a limiting column 19 capable of blocking the connecting rod 10 is arranged above the rotating shaft 9. In this way, the rotating angle of the rotating shaft 9 can be ensured to be fixed.

[0017] The material belt feeding mechanism of a tape attaching machine of the present invention has a material belt running path as shown in the attached Figure 1 As shown by the lines of the tension roller 7 wound around it, its working principle is that the material strip first enters from the first loosening mechanism 2, then enters the transmission mechanism 3 and the second loosening mechanism 4, and finally enters the taping part. Since the taping part will generate tension on the material strip during taping, the second loosening mechanism 4 is set to buffer the tension on the material strip.

When the material belt of the second belt loosening mechanism 4 is pulled, the transmission mechanism 3 needs to replenish the material belt. The motor 12 drives the transmission roller 13 to rotate. The material belt between the transmission roller 13 and the transfer roller 14 will be continuously pulled to the second belt loosening mechanism 4 under the action of friction. At this time, the second movable cylinder drives the second movable tension roller group 16 to reset. The action and principle of the first belt loosening mechanism 2 are the same as those of the second belt loosening mechanism 4. The first belt loosening mechanism 2 is to buffer the pulling force of the transmission mechanism 3.
