In the accompanying drawings, the same reference numerals generally represent the same components or steps.
[0029] Figure 1 The invention discloses a flow chart of the steps of producing small-size digital roll paper by a rewinding machine. DETAILED DESCRIPTION
[0030] In order to make the purpose, technical solution and advantages of the present disclosure more obvious, the exemplary embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described here.
[0031] As the technical problem pointed out in the background technology, the main reason why small-sized paper rolls cannot be directly produced by high-speed rewinders is that the width of small-sized paper rolls is relatively small, usually between 300 mm and 450 mm. When small-sized paper rolls are directly produced by rewinders, due to the small width, their center of gravity is unstable and they are easy to fall over during movement. Once the paper roll falls over, it will cause irreversible damage to the edge of the paper, and once the paper roll falls over, it is difficult to lift it up without damaging the paper. In the actual production process, the fallen paper rolls are usually re-copied into pulp, which increases the loss of the paper rolls.
[0032] In order to solve the above problems, the present invention proposes a method for producing small-sized digital roll paper by a rewinding machine, please refer to Figure 1 , which includes the following steps:
[0033] S1, cutting the base paper roll into a first paper roll group, a second paper roll group and a third paper roll group. In specific implementation, the first paper roll group, the second paper roll group and the third paper roll group are arranged in sequence. The first paper roll group includes at least two first paper rolls, the second paper roll group includes at least one second paper roll with a width greater than 600 mm, and the third paper roll group includes at least two third paper rolls; the widths of the first paper roll and the third paper roll are both no greater than 450 mm; the total widths of the first paper roll group and the total widths of the third paper roll are both no less than 800 mm; and the second paper roll group is located between the first paper roll group and the third paper roll group.
[0034] In practical applications, the purpose of setting up the second paper roll group is to facilitate the connection of the first paper roll group and the third paper roll group into a whole. The number of first paper rolls in the first paper roll group can be guaranteed according to actual needs, but at the same time, the following conditions must be met: the total length of the first paper roll group is not less than 800 mm, and the length of a single first paper roll is not more than 600 mm. For example, when the length of a single first paper roll is 350 mm, the number of first paper rolls in the first paper roll group should be at least 3.
[0035] The number of second paper rolls in the second paper roll group can be single or multiple, and the specific number is determined according to actual production requirements. When the demand for small-sized digital roll paper is large in the production task, the second paper roll in the second paper roll group can be set to one.
[0036] The number of third paper rolls in the third paper roll group can be guaranteed according to actual needs, but at the same time the following conditions must be met: the total length of the third paper roll group is not less than 800 mm, and the length of a single third paper roll is not more than 600 mm. For example, when the length of a single third paper roll is 350 mm, the number of third paper rolls in the third paper roll group should be at least 3. In practical applications, the number of the third paper roll group and the first paper roll group can be equal to or different from the number of first paper rolls in the first paper roll group. Although the first paper roll and the third paper roll are both small-sized digital rolls, their specifications are not necessarily the same. For example, the width of the first paper roll can be 300 mm, and the width of the third paper roll can be 400 mm. On the other hand, the widths of different first paper rolls in the same first paper roll group can also be different, such as the widths of two first paper rolls in a first paper roll group are 400 mm and 450 mm, respectively. Similarly, the widths of different third paper rolls in the same third paper roll group may also be different. For example, the widths of three third paper rolls in a third paper roll group are 300 mm, 350 mm and 400 mm respectively.
[0037] In actual applications, in order to monitor the information of the paper roll itself and produce logistics information, labels are generated when the original paper roll is cut into the first paper roll group, the second paper roll group and the third paper roll group; wherein each of the first paper roll, each of the second paper roll and each of the third paper roll corresponds to a label respectively.
[0038] S2, move out the second paper roll group; in specific implementation, multiple paper stoppers can be set to keep the positions of the first and third paper roll groups unchanged and move the second paper roll group. For example, the first paper stopper is used to ensure that the positions of the first and third paper roll groups remain unchanged, and the second paper roll group is rolled to the second paper stopper. In this way, sufficient space can be maintained between the first and third paper roll groups for subsequent operations. Since the second paper roll group is moved, the second paper roll is longer and less likely to fall over, which can ensure safer and more convenient operation.
[0039] S3, connecting all first paper rolls of the first paper roll group and connecting all third paper rolls of the third paper roll group.
[0040] The step of connecting all the first paper rolls of the first paper roll group includes step S31 and step S32. The step of connecting all the third paper rolls of the third paper roll group includes step S33 and step S34.
[0041] S31, insert the first tube core into the central hole of the first paper roll and pass through all the first paper rolls; specifically, the first tube core includes a first tube body and a first plug, the first tube body can be inserted into the inner hole of the first paper roll and pass through all the first paper rolls of the first paper roll group; at least one of the first plugs is detachably connected to the first tube body; one end of the first plug is connected to the first tube body, and the diameter of the other end is not less than the aperture of the inner hole of the first tube body. When the number of the first plug is one, a limiting structure should be provided at one end of the first tube body to cooperate with the first plug so that both ends of the first tube body can be fixed to the corresponding first paper roll.
[0042] S32, lock the first tube core and all the first paper rolls. After the first tube body passes through the first paper roll, insert the first plug into the two ends of the first tube body, and squeeze the first tube core against the inner wall of the first paper roll, so that the first tube core is pressed against the first paper rolls at both ends, thereby preventing the first paper rolls from detaching and falling over during the movement of the first paper roll group. In this way, a plurality of small-width paper rolls are combined into a large-width first paper roll group, which is helpful to prevent the first paper rolls from falling over during the rolling process and the transportation on the chain plate. In some implementations, the first plug and the first tube body are fitted in an interference fit, and in other implementations, they can also be threaded fit. As long as the first plug can press the first tube body against the inner wall of the first paper roll, it will be sufficient.
[0043] S33, insert the second tube core into the central hole of the third paper roll and penetrate all the third paper rolls; specifically, the second tube core includes a second tube body and a second plug, the second tube body can be inserted into the inner hole of the third paper roll and penetrate all the third paper rolls of the third paper roll group; at least one second plug is detachably connected to the second tube body; one end of the second plug is connected to the third tube body, and the diameter of the other end is not less than the aperture of the inner hole of the second tube body. When the number of the second plug is one, a limiting structure should be provided at one end of the second tube body to cooperate with the second plug so that both ends of the second tube body can be fixed to the corresponding third paper roll.
[0044] S34, lock the second tube core and all the third paper rolls. After the second tube body passes through the third paper roll, the second plug is inserted into the two ends of the second tube body, and the second tube core is squeezed against the inner wall of the third paper roll, so that the second tube core is pressed against the third paper rolls at both ends, thereby preventing the third paper rolls from detaching and falling during the movement of the third paper roll group. In this way, a plurality of small-width paper rolls are combined into a large-width third paper roll group, which is conducive to preventing the third paper rolls from falling during the rolling process and the transportation process on the chain plate. In some implementations, the cooperation between the second plug and the second tube body is an interference fit, and in other implementations, it can also be a threaded fit. As long as the second plug can press the second tube body against the inner wall of the third paper roll. In specific implementations, the first tube body and the second tube body are both paper tubes. In some implementations, the first plug and the second plug can be metal or hard plastic.
[0045] After all the first paper rolls of the first paper roll group are connected, the labels corresponding to all the first paper rolls in the first paper roll are pasted to one end of the first paper roll group, and one of the labels is determined to be the first main label; and the information corresponding to all the labels corresponding to the first paper roll group is synchronized to the first main label. In this way, the information of all the first paper rolls is merged. Similarly, the labels corresponding to all the third paper rolls in the third paper roll are pasted to one end of the third paper roll group, and one of the labels is determined to be the second main label; and the information corresponding to all the labels corresponding to the third paper roll group is synchronized to the second main label.
[0046] S4, respectively moving the connected first paper roll group and the connected third paper roll group to the chain plate for packaging. After the first paper roll group and the third paper roll group are respectively connected, the first paper roll group and the third paper roll group each form a whole, and the corresponding width becomes larger, which can avoid tipping over during rolling or moving through the plate chain, thereby reducing loss.
