[0002] For the packaging of liquid food, especially in the field of packaging of dairy products and beverages, six-layer composite paper composed of paper, aluminum and plastic is usually used for packaging. This type of six-layer composite paper has good water barrier properties, gas barrier properties, light barrier properties, high stiffness and printability, and can effectively guarantee the quality of dairy products and beverages, and has a long product shelf life, thereby achieving high packaging efficiency and convenience and safety for consumers. In the specific production process, the packaging material is often sealed as a whole by means of horizontal sealing and vertical sealing. For example, when performing vertical sealing, the packaging material will form a paper tube, and it needs to be longitudinally sealed at the center seam overlap before filling to enhance the joint strength of the vertical seal and prevent liquid seepage. In other words, the vertical sealing effect plays a key role in the quality of the product. Currently, the strips in the longitudinal sealing strip system are all operated under the action of traction. However, since the traction force it is subjected to constantly changes during the entire operation process, the strips often have problems with deformation or breakage, which causes frequent wheel jumping and entanglement. Ultimately, the packaging material is not sealed tightly, the sealing is interrupted, or the equipment needs to be shut down for processing. This not only causes production interruptions and cost losses, but also the poor sealing can cause serious quality problems. Therefore, how to ensure that the longitudinal sealing strip supply device can be highly compatible with the filling machine equipment, and ensure that the strip operation and consumption are smooth, ensure the effective sealing of the packaging material, and reduce the cost losses caused by frequent wheel jumping and strip entanglement are currently problems that need to be solved by people in this field.

[0026] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0027] like Figure 1-Figure 3 As shown, this embodiment provides a longitudinal sealing strip supply device, including a supply body 100 and a roller group 200. The supply body 100 is provided with a strip roll 11, and at least one spare strip roll 12 is provided. The strips on the strip roll 11 can be guided to the fifth guide wheel 300 by the roller group 200 so as to be heat-sealed with one side of the subsequent packaging material. The strips on the spare strip roll 12 can be spliced with the end of the strip on the strip roll 11 and then guided to the fifth guide wheel 300 via the roller group 200. A bracket 20 is provided under the strip roll 11 and the spare strip roll 12. The roller group 200 can move in a vertical direction relative to the supply body 100 through a slider 70, and a counterweight block 60 is provided on the roller group 200.
[0028] Specifically, in this embodiment, the provision of the spare strip roll 12 and the technical means by which the spare strip roll 12 can be spliced with the strip roll 11 can effectively ensure the smooth operation and consumption of the strips and ensure the sustainability of production. Furthermore, a bracket 20 is provided below the strip roll 11 and the spare strip roll 12, which can effectively prevent the strips from being entangled after the wheels jump. Accordingly, the strips can be guided to the longitudinal sealing strip of the packaging material by multiple rollers, so as to achieve a high degree of matching with the filling machine equipment and ensure the continuity of production, and the roller group 200 can move in the vertical direction relative to the supply body 100 under the action of the slider 70, so as to cooperate with the splicing process of the strips and ensure smooth splicing. Furthermore, a linear bearing is provided on the roller group 200, and the baffle 50 is located above the linear bearing. During the splicing operation, the linear bearing will not fall off under the limiting action of the baffle 50. Furthermore, a counterweight block 60 is provided on the roller assembly 200, which can effectively ensure that the force on the roller assembly 200 is uniform, thereby maintaining overall balance during lifting and moving, and avoiding failure in splicing the strips.
[0029] The specific structure of the longitudinal sealing strip supply device in this embodiment is described below.
[0030] like Figure 1 and Figure 3As shown, in this embodiment, the longitudinal sealing strip supply device includes a supply body 100 and a roller group 200, so as to ensure the supply of strips for subsequent heat-sealing on one side of the packaging material. Specifically, the supply body 100 is provided with a strip roll 11, a spare strip roll 12, a bracket 20, a splicing structure 30, a cutting structure 40 and a slider 70, and the roller group 200 is provided with a plurality of guide wheels, and is provided with a baffle 50 and a counterweight 60. Optionally, the strip roll 11 and the spare strip roll 12 can both provide strips, and can be guided to the fifth guide wheel 300 under the guidance of the roller group 200, so as to facilitate heat-sealing with one side of the subsequent packaging material to complete the longitudinal sealing effect of the product packaging. Furthermore, the bracket 20 is arranged below the strip roll 11 and the spare strip roll 12 to avoid the strip from breaking or otherwise becoming entangled and affecting the operation of the entire device. For example, a splicing station is provided on the supply body 100, and the splicing structure 30 and the cutting structure 40 are both provided at the splicing station, so that the spare strip roll 12 and the strip roll 11 can be spliced to improve production efficiency. Furthermore, the slider 70 is provided on the supply body 100 in a sliding manner in the vertical direction, and the roller assembly 200 is fixed to the slider 70, so that under the action of the slider 70, the roller assembly 200 can move in the vertical direction relative to the supply body 100 to cooperate with the splicing operation and avoid the strip breakage. In other embodiments, the movement of the slider 70 or the roller assembly 200 in the vertical direction on the supply body 100 can also be achieved by other means, such as a lead screw nut, etc., which will not be repeated here. Furthermore, a linear bearing is provided on the roller assembly 200, and the baffle 50 is located above the linear bearing, so that when the roller assembly 200 moves up and down relative to the supply body 100, that is, during the splicing operation, the linear bearing will not fall off under the limiting action of the baffle 50. Likewise, the roller assembly 200 is provided with a counterweight 60 to ensure that the roller assembly 200 is subjected to balanced force when moving up and down, and the roller will not jump.
[0031] like Figure 1 and Figure 2As shown, specifically, in this embodiment, there is one sticker roll 11 and at least one spare sticker roll 12, thereby ensuring that there are at least two sticker inventory locations in the entire device, ensuring the effect of continuous production, improving production efficiency, and avoiding the waste of time such as shutdown and replacement. By way of example, in other embodiments, the number and position of the spare sticker roll 12 can also be set as needed, which is not limited here. By way of example, in this embodiment, the sticker roll 11 and the spare sticker roll 12 are arranged relative to each other, and the directions in which the stickers on the two are rotated and exported are opposite, thereby improving the overall space utilization of the supply body 100 and ensuring the smooth splicing of the sticker roll 11 and the spare sticker roll 12 at the splicing station. Specifically, in this embodiment, the strips on the strip roll 11 can be guided by the roller assembly 200 to the fifth guide wheel 300 for subsequent heat-sealing of the packaging material on one side. The strips on the spare strip roll 12 can be spliced with the end of the strips on the strip roll 11 and then guided to the fifth guide wheel 300 by the roller assembly 200. This ensures a continuous supply of longitudinal sealing strips and achieves the purpose of continuous production. For example, the strips on the strip roll 11 and the spare strip roll 12 are both configured as MPM sealing strips.
[0032] like Figure 1 and Figure 2 As shown, the supply body 100 is further provided with a first guide wheel 101, a second guide wheel 102, a first sensor 103, and a second sensor 104. Optionally, the strips on the strip roll 11 can be guided to the splicing station via a plurality of first guide wheels 101, and the strips on the spare strip roll 12 can be guided to the splicing station via a plurality of second guide wheels 102, thereby achieving smooth guidance of the strips. Exemplarily, at least three first guide wheels 101 and two second guide wheels 102 are provided, thereby ensuring that the strips on the strip roll 11 and the spare strip roll 12 can be smoothly guided to the splicing station within the limited space of the supply body 100. Furthermore, a first sensor 103 is provided above the strip roll 11, and a second sensor 104 is provided above the spare strip roll 12, and the first sensor 103 is used to detect whether the strips on the strip roll 11 are exhausted and the time point when they are exhausted, and the second sensor 104 is used to detect whether the strips on the spare strip roll 12 are exhausted and the time point when they are exhausted, so as to indicate the splicing time point and corresponding cutting operation at the subsequent splicing station. For example, in this embodiment, the first guide wheel 101 and the second guide wheel 102 are both configured as widened guide wheels, and their wheel width can be set to 6.5cm, so as to greatly increase the activity space of the strips during the rotation process, thereby avoiding the friction problem between the strips and the guide wheel after its high-speed rotation, and the situation where the strips slip out of the guide wheel. Optionally, the first sensor 103 and the second sensor 104 are both configured near the strip roll 11 and the spare strip roll 12, so as to capture the time point of exhaustion as early as possible, so as to facilitate the transmission of information to the splicing station.
[0033] Combine Figure 1 and Figure 2 As shown, in this embodiment, a bracket 20 is provided below both the strip roll 11 and the spare strip roll 12. In this embodiment, the bracket 20 is configured as an arc-shaped structure, and its curvature is adapted to the curvature of the strip roll 11 and the spare strip roll 12. Furthermore, the gaps between the bracket 20 and the strip roll 11 and the spare strip roll 12 are adjustable. This not only prevents the strip from becoming entangled after it breaks, but also ensures that the strip will not continue to fall off and become entangled after it breaks or is exhausted and jumps off the wheel through adjustment of its position.
[0034] like Figure 1 As shown, in this embodiment, the splicing station is mainly used for splicing the strips on the strip roll 11 and the spare strip roll 12. Optionally, when splicing is not performed, the strips on the strip roll 11 can be guided to the fifth guide wheel 300 by the roller group 200 after passing through the splicing station, and the head end of the spare strip roll 12 can be snapped into the splicing station to wait for subsequent splicing with the strips on the strip roll 11. Specifically, a splicing structure 30 and a cutting structure 40 are provided at the splicing station, and the head end of the spare strip roll 12 can be snapped into the cutting structure 40. When the strip roll 11 is used up, the splicing structure 30 can splice the head end of the spare strip roll 12 to the end of the strip roll 11, and the excess part of the strip splicing is cut off by the cutting structure 40, so as to ensure that there are no problems with the subsequent guidance and bonding of the strips. For example, the first sensor 103 and the second sensor 104 are both communicatively connected to the splicing structure 30 and the cutting structure 40 , so as to realize their automatic identification and operation, and avoid manual intervention affecting continuous production.
[0035] Furthermore, a third guide wheel is provided between the splicing station and the roller group 200, and a fourth guide wheel 105 is provided between the roller group 200 and the fifth guide wheel 300. Thus, under the action of the third guide wheel, the strips passing through the splicing station can be guided to the roller group 200, and under the action of the fourth guide wheel 105, the strips guided by the roller group 200 can be guided to the fifth guide wheel 300. Accordingly, the number and position of the third guide wheel and the fourth guide wheel 105 can be set as needed. Figure 1 and Figure 3 As shown, in this embodiment, the slider 70 is provided on the supply body 100 , and under the action of the slider 70 , the roller assembly 200 can move in the vertical direction relative to the supply body 100 , so as to cooperate with the splicing station.
[0036] like Figure 3As shown, a baffle 50 is provided on the roller assembly 200 and is located above the linear bearing, so as to prevent the bearing inside the roller assembly 200 from moving during the splicing and lifting process, causing the lifting to be blocked, thereby causing the splicing to fail. For example, in this embodiment, the baffle 50 is set to 1.5cm*5cm, and in other embodiments it can be set as needed. Furthermore, a 70g counterweight block 60 is provided on the roller assembly 200, so that the weight can be equipped according to the lifting conditions of different splicing, avoiding uneven force on the roller assembly 200, thereby reducing the wheel jumping phenomenon, and allowing the splicing operation to proceed smoothly.
[0037] Working process: When the splicing operation is not performed, the strips on the strip roll 11 are first guided to the splicing station by the first guide wheel 101 under the traction of the packaging material, and after passing through the splicing station, they are guided to the roller group 200 under the action of the third guide wheel. After being guided by the roller group 200, they are wound around the fourth guide wheel 105, and finally reach the fifth guide wheel 300. After passing through multiple rollers, the strips are guided to the longitudinal sealing strip of the packaging material, thereby completing the heat sealing and bonding on one side of the packaging material. When performing the splicing operation, the head end of the spare strip roll 12 is first clamped on the cutting structure 40 in the splicing station and waits for splicing. Then, when the first sensor 103 senses that the strip roll 11 is exhausted, the splicing time is accurately determined. At the same time, the roller group 200 is raised to a certain height as a whole through the slider 70. Then, at the splicing time, the head end of the spare strip roll 12 and the end of the strip roll 11 are spliced through the splicing structure 30. Then, the excess strip part at the splicing point is cut off through the cutting structure 40 to complete the splicing and proceed with subsequent production. Therefore, the longitudinal sealing strip supply device in this embodiment can smoothly operate the strip consumption and stably splice and convert, avoiding the problems of wheel jumping and strip entanglement, ensuring the efficient and high-quality function of the longitudinal sealing strip of the filling machine packaging material, greatly reducing cost losses, and improving production efficiency and product integrity.

Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
