Description

TECHNICAL FIELD

[0001] The utility model relates to winding packaging technical field, concretely relates to a self -rotation subassembly, winding mechanism and winding machine for adhesive tape winding. BACKGROUND

[0002] In the packaging technical field, it is extremely important to use adhesive tape to wind and package objects. Non-integer winding of adhesive tape can achieve sealing of the wound objects (such as cartons, turnover boxes, and certain shaped packaged objects, etc.), while integer winding can increase the sealing strength or enhance the strength of the entire packaged object, which helps to ensure the integrity of the wound object during transportation and storage, preventing the object from scattering or being damaged. With the vigorous development of the logistics industry and the increasing demand for product packaging, higher requirements are placed on the performance and efficiency of adhesive tape winding equipment.

[0003] The common automatic winding machine on the market is usually installed with an adhesive tape mounting plate on a toothed ring / turntable / rotating wheel that can rotate by itself. As the toothed ring / turntable rotates, it drives the adhesive tape on the adhesive tape mounting plate to wind around the packaging box.

[0004] For example, the winding packaging machine shown in patent announcement No. CN216806058U uses a gear and toothed ring meshing drive method to rotate the adhesive tape mounting plate. This driving method has significant advantages, which can ensure the stable rotation of the adhesive tape mounting plate with the toothed ring, and thus ensure the stability of the adhesive tape during winding, so that the adhesive tape can be evenly and tightly wound on the surface of the packaging box, greatly improving the quality and effect of packaging. However, the gear and toothed ring meshing method also has some disadvantages that cannot be ignored. Due to the complex manufacturing process of gears and the high precision requirement, the cost is high. This not only increases the initial purchase cost of the equipment, but also greatly increases the maintenance and replacement cost in the later stage, which brings a large economic burden to the enterprise and limits the wide application of this technology in the market field which is sensitive to cost.

[0005] In order to reduce the cost, some adhesive tape winding equipment has borrowed from other transmission methods, such as the belt drive method used in patent announcement No. CN216836483U and CN207157624U. In the automatic adhesive tape winding machine of CN216836483U, the driving motor is connected with the belt transmission mechanism to rotate the turntable, realizing the rotation of the adhesive tape to wind the adhesive tape; the waterproof roll packaging machine of CN207157624U uses a driving wheel to rotate the rotating wheel through a belt, thereby realizing the winding of the protective film. Compared with the gear and toothed ring meshing method, the belt drive method has obvious advantages in cost, with relatively simple structure, low manufacturing and maintenance cost, which greatly reduces the overall cost of the equipment and improves the market competitiveness of the product.

[0006] But in the actual application process, the belt drive mode also exposed the problem, in the belt drive mode, winding mechanism exists abnormal sound, this abnormal sound is related to the different speed of pulling out when winding, and is related to the different position of the belt movement and the different pressure of the auxiliary wheel (also called supporting wheel) supporting the rotating disc.

The driving machine 11 is fixedly installed on the machine frame 10, and a front mounting plate 101 and a rear mounting plate 102 are fixedly installed on the machine frame 10. The front mounting plate 101 and the rear mounting plate 102 are fixedly connected by a plurality of connecting columns / connecting blocks 103 to form a cage frame. All the supporting wheels 13 and the sets of pressing wheels 14 are located between the front mounting plate 101 and the rear mounting plate 102. The supporting wheels 13 are rotatably connected to the front and rear mounting plates.

[0042] In this embodiment, there are four supporting wheels 13. The driving machine 11 drives the rotating wheel 12 to rotate through a belt drive. In this embodiment, there are three sets of pressing wheels 14. Each set of pressing wheels 14 comprises a pressing arm 141, a pressing roller 142 and a first elastic member 143. The pressing roller 142 is rotatably connected to the pressing arm 141. The first elastic member 143 is connected between the pressing arm 141 and the machine frame 10. The first elastic member 143 is used to press the pressing roller 142 towards the rotating wheel 12. The pressing roller 142 is located above the supporting wheel 13 and is located with the supporting wheel 13 outside the periphery of the rotating wheel 12. The rotating wheel 12 is supported by the supporting wheel 13 and rotates within the enclosed area of the supporting wheel 13 and the pressing roller 142. The rotating wheel 12 and the supporting wheel 13 are in concave-convex cooperation at the contact part. The rotating wheel 12 and the pressing roller 142 are also in concave-convex cooperation at the contact part (as shown in FIG. 6). In this embodiment, a groove is provided on the periphery of the rotating wheel 12. The supporting wheel 13 and the pressing roller 142 are both sunk into the groove 121 of the rotating wheel 12. In this embodiment, the first elastic member 143 is a spring. Figure 2

[0043] In combination Figure 3 and Figure 4 In one of the schemes of the set of pressing wheels 14, the pressing arm 141 is located between the front mounting plate 101 and the rear mounting plate 102 and is rotatably connected to the front and rear mounting plates.

[0045] The pressing wheel set 14 of the embodiment has simple structure, and adjusts the pressing force of the pressing roller 142 on the rotating wheel 12 under the swing of the pressing arm 141 or realizes the adjustment of the pressing force on the rotating wheel 12 under the sliding of the pressing arm 141 relative to the frame 10. Whether the swing mode or the linear sliding mode can meet the requirement of the floating pressing force on the rotating wheel 12. Under the floating pressing force, even if the pulling-out speed of the rubber belt is inconsistent during the winding process, the pressure on each pressing roller 142 / support wheel 13 is inconsistent due to the uneven force on the rotating wheel 12, the elastic force of the first elastic member 143 can ensure that the rotating wheel 12 is always in contact with the plurality of pressing rollers 142 and support wheels 13, thereby ensuring the stable rotation of the rotating wheel 12, greatly reducing or even avoiding the situation that the rotating wheel 12 impacts the pressing roller 142 / support wheel 13 to emit abnormal sound due to the uneven circumferential force on the rotating wheel 12 during the winding process of the rubber belt, reducing the noise of the winding mechanism during winding. In addition, the contact between the pressing wheel set 14 and the rotating wheel 12 can be adaptively adjusted, thereby reducing or even avoiding the noise and abnormal sound while reducing the machining precision requirement of the rotating wheel 12.

[0046] In addition, the front mounting plate 101 and the rear mounting plate 102 are provided, so that the force on the rotating wheel 12 is transmitted to the front and rear mounting plates through the support wheel 13 and the pressing wheel set 14, thereby ensuring the stability and uniformity of the force on the rotating wheel 12; in addition, the front and rear mounting plates can be thin plates, thereby reducing the machining cost and manufacturing cost.

[0047] In combination with Figure 3The first tensioning wheel set 15 is arranged on the rack 10 and used for controlling the tensioning force of the transmission belt, and comprises a first tensioning arm 151, a first tensioning roller 152 and a second elastic member 153.

The first tensioning roller 152 is used for contacting the belt. The second elastic member 153 enables the first tensioning roller 152 to abut against the belt. In the embodiment, the second elastic member 153 is a spring.

[0048] The output wheel of the driving machine 11 is sleeved with the belt. The belt directly drives the rotating wheel 12 to rotate. The belt is clamped between the supporting wheel 13 / the pressing roller 142 and the surface of the rotating wheel 12. After the driving machine 11 is started, the rotating wheel 12 is directly driven to rotate by the belt. During the rotation process, the supporting wheel 13 and the pressing roller 142 are rolled and limit the rotating wheel 12 from the top and bottom positions.

[0049] In the embodiment, the first tensioning wheel set 15 with the first tensioning roller 152 and the second elastic member 153 is arranged to adjust the tensioning force of the belt transmission of the driving machine 11, so as to ensure the stability and reliability of the belt transmission.

The adhesive tape mounting rack 200 is provided with a second tensioning wheel set 21 and a sound-eliminating wheel set 22. The adhesive tape on the adhesive tape mounting rack 200 passes through the sound-eliminating wheel set 22, then passes through the guide roller on the adhesive tape mounting rack 200, and then passes through the second tensioning wheel set 21 for winding.

[0052] The second tensioning wheel set 21 comprises a second tensioning arm 211, a second tensioning roller 212 and a third elastic member 213. The second tensioning roller 212 is rotatably connected to the second tensioning arm 211. The third elastic member 213 is connected between the second tensioning arm 211 and the tape mounting rack 200. The second tensioning roller 212 is used to contact the pulled-out tape.

The third elastic member 213 adjusts the tensioning force of the pulled-out tape, and ensures that the tape is always kept in a straight state during winding.

[0053] In combination Figure 7 In one scheme of the second tensioning wheel set 21, the second tensioning arm 211 is rotatably connected to the tape mounting rack 200. The second tensioning roller 212 is rotatably connected to a cantilever section of the second tensioning arm 211. One end of the third elastic member 213 is connected to the tape mounting rack 200, and the other end is connected to the cantilever section of the second tensioning arm 211. The third elastic member 213 enables the second tensioning arm 211 to swing.

[0054] In combination Figure 8 In one scheme of the second tensioning wheel set 21, the second tensioning arm 211 is slidably connected to the tape mounting rack 200. The third elastic member 213 is in the sliding direction of the second tensioning arm 211. The third elastic member 213 enables the second tensioning arm 211 to slide.

[0055] The muffling wheel set 22 comprises a muffling arm 221, a muffling roller 222 and a fourth elastic member 223. The muffling roller 222 is rotatably connected to the muffling arm 221. The fourth elastic member 223 is connected between the muffling arm 221 and the tape mounting rack 200. The muffling roller 222 is used to contact the pulled-out tape.

The fourth elastic member 223 is in the sliding direction of the muffling arm 221. The fourth elastic member 223 enables the muffling arm 221 to slide away from or close to the film.

[0058] The presence of the noise-silencing roller assembly 22 with the fourth elastic element 223 and the noise-silencing roller 222 ensures that when the tape is pulled out of the film roll, the fourth elastic element 223 always exerts a force on the noise-silencing roller 222 to pull the tape away from the film roll. When the pulling speed is too low, the noise-silencing roller assembly 22 cooperates with the second tensioning roller assembly 21 to slow down the tape pulling speed while keeping it taut. When the pulling speed needs to be increased, the tension of the tape will be automatically adjusted by the second tensioning roller assembly 21 and the noise-silencing roller assembly 22 to ensure that the tape is not too taut while also avoiding the hissing and piercing sound of instantaneous rapid pulling, thus reducing abnormal noise during the tape wrapping process.
