[0002] Paper roll glue spraying tail sealing device is provided with glue spraying mechanism and the unfolding mechanism that is unfolded paper tail for glue spraying mechanism. The unfolding mechanism is unfolded paper tail of paper roll by the air current that the air blower blows. Glue is sprayed by glue spraying mechanism to unfolded paper tail. Since the position of paper tail end of every paper roll sent to unfolding mechanism in the circumferential direction of paper roll is random, and cannot guarantee that the air blower can unfold paper tail (for example, paper tail end may just press on the bottom of paper roll), when paper roll is sent to unfolding mechanism, the air blower cannot immediately unfold paper tail, and must first rotate paper roll, and adjust paper tail to the position that can be blown up by the air blower. This increases the time of glue spraying mechanism waiting for paper tail to unfold. Therefore, the existing paper roll glue spraying tail sealing device has the problem of low work efficiency.

[0025] In order to facilitate the understanding of the present application, the present application will be described more comprehensively through the embodiments. The embodiments give the implementation manners of the present application. However, the present application can be realized in many different forms and is not limited to the implementation manners described in the embodiments.
[0026] It should be noted that the "first" and "second" in the present application are only used for name distinction and do not represent the specific quantity and order. Embodiment one
[0027] Referring to Figure 1 , the paper roll glue spraying and tail sealing device is provided with a rotating roller 1, a circulating walking drive belt 2, a second air blowing nozzle 4 and a sensor 5. As shown in Figure 2 , the drive belt 2 and the rotating roller 1 together clamp the paper roll 3 and drive the paper roll 3 to rotate in place around the axis of the paper roll 3. The drive belt 2 and the rotating roller 1 constitute the driving part of the embodiment for driving the paper roll to rotate in place around the axis of the paper roll 3. As shown in Figure 3 , the second air blowing nozzle 4 blows air towards the paper roll 3 rotating in place so as to unwind the paper tail 3a of the paper roll 3. Whether the paper tail of the paper roll rotating in place has been unwound is sensed by the sensor 5. The driving part, the second air blowing nozzle 4 and the sensor 5 constitute the tail-seeking mechanism of the embodiment for determining the position of the paper tail of the paper roll.
[0028] Referring to Figure 1 , the paper roll glue spraying and tail sealing device is provided with a groove 6 and a first air blowing nozzle 7. The groove 6 and the first air blowing nozzle 7 constitute the unwinding mechanism of the embodiment. As shown in Figure 5As shown, the paper roll 3 is supported by the groove 6, and the paper roll 3 stopped at the groove 6 when rolling to the unwinding mechanism. As shown Figure 5 , the first air blowing nozzle 7 blows air towards the paper roll 3 in the groove 6, so that the paper tail 3a of the paper roll 3 is unwound.
[0029] As shown Figure 1 , the paper roll glue spraying and tail sealing device is provided with a glue spraying mechanism 8 for spraying glue towards the unwound paper tail of the unwinding mechanism. When the glue spraying mechanism 8 finishes spraying glue towards the paper tail, as shown Figure 6 , the groove 6 is turned upward so that the paper roll 3 rolls out of the groove 6. The groove 6 can be driven by a pneumatic cylinder, a motor or other means.
[0030] As shown Figure 1 , a supporting table 9 is arranged between the tail searching mechanism and the unwinding mechanism. As shown Figure 4 , the transmission belt 2 is pressed on the top of the paper roll 3, so as to drive the paper roll 3 to roll along the supporting table 9. The supporting table 9 and the transmission belt 2 constitute a paper roll rolling mechanism of the embodiment for driving the paper roll to roll from the tail searching mechanism to the unwinding mechanism. In fact, the tail searching mechanism and the paper roll rolling mechanism of the embodiment share the same transmission belt 2. The path of the paper roll 3 from the tail searching mechanism to the unwinding mechanism is set to a specific length, which makes the paper tail of the paper roll 3 be in a position that can be unwound by the air flow blown by the first air blowing nozzle 7 of the unwinding mechanism when the paper roll 3 rolls to the unwinding mechanism and stops, as shown Figure 5 .
[0031] The working principle of the embodiment will be further described in detail below with reference to the drawings. As shown Figure 2 , the paper rolls 3 to be sealed are sent to the tail searching mechanism one by one by a paper roll distributor 10 (or an upstream device). When the paper roll 3 rolls to a position clamped between the transmission belt 2 and the rotating roller 1, the transmission belt 2 and the rotating roller 1 drive the paper roll 3 to rotate in place around its own axis. While the paper roll 3 rotates in place, the second air blowing nozzle 4 blows air towards the paper roll 3. No matter whether the paper tail of the paper roll is in a position that can be unwound by the air flow blown by the second air blowing nozzle 4 when the paper roll enters the air flow range of the second air blowing nozzle 4, the paper tail will eventually rotate to the position that can be unwound by the air flow blown by the second air blowing nozzle 4 with the rotation of the paper roll. When the sensor 5 detects the unwound paper tail 3a, it means that the tail searching mechanism determines the position of the paper tail. As shown Figure 3 , when the sensor 5 detects the unwound paper tail 3a, the speed of the transmission belt 2 is greater than the outer circular line speed of the rotating roller 1 (the rotating speed of the rotating roller 1 can be zero), so that the transmission belt 2 drives the paper roll 3 to roll along the supporting table 9, and the paper roll 3 falls into the groove 6 of the unwinding mechanism and stops rolling, as shown Figure 4 to Figure 5 . The path of the paper roll 3 from the tail searching mechanism to the unwinding mechanism, that is, the paper roll 3 rolls from the Figure 3 position shown to the Figure 5The path traversed by the indicated position is set to a specific length, such that when the paper roll 3 rolls to the unfolding mechanism and stops rolling, the tail of the paper roll 3 is already in a position where it can be unfolded by the airflow blown out by the first air nozzle 7. Therefore, the tail-finding mechanism determines the position of the paper roll's tail and the process of the paper roll rolling from the tail-finding mechanism to the unfolding mechanism, thus adjusting and unifying the position of the paper roll's tail. This ensures that the tail of each paper roll that rolls to the unfolding mechanism is necessarily in a position where it can be unfolded by the airflow blown out by the first air nozzle 7 of the unfolding mechanism. As long as the paper roll 3... Figure 5 As shown, once the paper roll rolls to the unfolding mechanism, the first air nozzle 7 immediately unfolds the paper tail 3a, eliminating the need for the unfolding mechanism to rotate the paper roll and improving its efficiency. When the unfolding mechanism... Figure 5 As shown, after the paper roll 3 is unrolled, glue is immediately sprayed onto the unrolled paper tail 3a by the glue spraying mechanism 8. The glue spraying mechanism 8 travels parallel to the paper roll axis while spraying glue, ensuring that the unrolled paper tail 3a is covered with glue across the entire width of the paper. Then, as... Figure 6 As shown, the groove 6 of the unfolding mechanism flips upward, causing the paper roll 3 to roll out of the groove 6. The paper roll 3, which rolls out of the groove 6, rolls over the paper tail that has been glued, and the paper tail sticks to the paper roll 3, thus completing the paper roll sealing work.
[0032] The above-described process applies only to a single roll of paper. In a continuous production process, after the previous roll leaves the tail-finding mechanism, the roll distributor (or upstream equipment) can send the next roll to be sealed to the tail-finding mechanism. Furthermore, the tail-finding mechanism's action of determining the tail position of the next roll can be performed simultaneously with the glue spraying mechanism's action of spraying glue towards the tail of the previous roll. This effectively shortens the time required to adjust the tail position of the next roll, thereby improving the overall efficiency of the paper roll glue spraying and sealing device.
[0033] The above-described process can be further optimized. When sensor 5... Figure 3 After sensing the unfolded paper tail 3a, the paper roll is not immediately rolled out of the tail-finding mechanism. Instead, the drive unit of the tail-finding mechanism continues to rotate the paper roll 3 around its own axis, causing the unfolded paper tail 3a to rewind. The second air nozzle should ideally stop blowing air when the paper tail 3a rewinds. When sensor 5... Figure 7 When the end 3b of the rewinding paper tail just passes the sensor 5, the drive unit continues to rotate the paper roll 3 around its own axis, causing the unfolded paper tail to continue rewinding until the unfolded paper tail is completely rewinded and the end of the paper tail has just rotated to the predetermined position in the circumferential direction of the paper roll. Only then does the operation begin. Figure 4 to Figure 5The action of driving the paper roll from the tail searching mechanism to the unrolling mechanism is shown. After the improvement, the utility model can flexibly adapt to paper rolls with different diameters. When producing different batches of paper rolls with different diameters, only the predetermined position of the tail end of the paper roll in the circumferential direction of the paper roll needs to be adjusted in the tail searching mechanism to ensure that the tail of the paper roll rolled to the unrolling mechanism is necessarily in the position that can be unrolled by the air flow blown by the first blowing nozzle of the unrolling mechanism, without the need to change the path length from the tail searching mechanism to the unrolling mechanism due to the change of the diameter of the paper roll. This effect can be illustrated as follows. Figure 8 Suppose that for the paper roll 3 with the diameter shown in Figure 8 (a), the tail searching mechanism needs to rotate the tail end of the paper roll to the predetermined position M1 in the circumferential direction of the paper roll, as shown in Figure 8 (a), so that the tail of the paper roll rolled to the unrolling mechanism is just in the position N that can be unrolled by the air flow blown by the first blowing nozzle, then for the paper roll 3 with a different diameter shown in Figure 8 (b), the predetermined position of the tail end of the paper roll in the circumferential direction of the paper roll can be changed by the tail searching mechanism, for example, the tail end of the paper roll is rotated to the position M2 shown in Figure 8 (b), so that the tail of the paper roll rolled to the unrolling mechanism in 8(b) is still in the same position N as in Figure 8 (a), without the need to change the path length from the tail searching mechanism to the unrolling mechanism due to the change of the diameter of the paper roll. The position of the sensor in the device is determinable, and the rotation angle of various rotating parts including the rotating roller is a conventional setting in the electric control system of the paper roll glue spraying and tail sealing device. Therefore, it is very convenient to change the predetermined position of the tail end of the paper roll in the circumferential direction of the paper roll in the tail searching mechanism at any time through the man-machine exchange interface of the electric control system.
[0034] The above-mentioned optimization scheme has another advantage: only the predetermined position of the tail end of the paper roll in the circumferential direction of the paper roll needs to be changed in the tail searching mechanism to change the length of the unrolled tail of the paper roll rolled to the unrolling mechanism, and the distance between the glue spraying mechanism and the unrolling mechanism is unchanged, so that the distance between the glue sprayed on the tail of the paper roll by the glue spraying mechanism and the tail end of the paper roll can be conveniently adjusted.
[0035] As a simplified scheme of the above-mentioned optimization scheme, when the sensor 5 senses that the tail end 3b of the paper roll in the unrolling mechanism just passes through the sensor 5, as shown in Figure 7 , the action of driving the paper roll from the tail searching mechanism to the unrolling mechanism is immediately performed, as shown in Figure 4 to Figure 5 . Embodiment Two
[0036] Referring to Figure 7One difference between this embodiment and Embodiment 1 is that the drive belt 2 of the tail-finding mechanism and the drive belt 11 of the paper roll rolling mechanism are two independently operating drive belts. The two drive belts 2 and 11 are driven in a cyclical motion by drive pulleys 12 and 13, respectively. The driven pulleys 14 and 15 of the two drive belts 2 and 11 are mounted on the same rotating shaft and can rotate freely. See also... Figure 7 Another difference between this embodiment and Embodiment 1 is that the unfolding mechanism is omitted. Figure 1 The groove 6 is shown. See also... Figure 8 When the drive belt 11 drives the paper roll 3 to roll to the unfolding mechanism, the drive belt 11 stops running but still presses down on the top of the paper roll 3. After the glue spraying mechanism 8 finishes spraying glue towards the unfolded paper tail 3a, the drive belt 11 resumes operation, driving the paper roll 3 to roll over the glued paper tail 3a, so that the paper tail 3a sticks to the paper roll 3. For details not described in this embodiment, please refer to Embodiment 1. Example 3
[0037] See Figure 9 The difference between this embodiment and Embodiment 1 is that neither the tail-finding mechanism nor the paper roll rolling mechanism uses a drive belt. The drive unit of the tail-finding mechanism consists of two parallel rotating rollers 16 and 17. The two rotating rollers 16 and 17 together support the paper roll 3 and drive the paper roll 3 to rotate in place around its own axis. The paper roll rolling mechanism in this embodiment is provided with a pusher 18 that pushes the paper roll 3 from the tail-finding mechanism to the support platform 9. After the two rotating rollers 16 and 17 unfold the paper tail 3a of the paper roll 3 to a predetermined length, the pusher 18 immediately... Figure 10 The paper roll 3 is flipped upwards, pushing it to roll onto the support platform 9. The paper roll 3 continues to roll on the support platform 9 due to inertia until it falls into the groove 6 of the unfolding mechanism and stops rolling. It should be noted that the action of the pusher 18 is not limited to upward flipping; for example, it can be horizontal translation. The pusher 18 can be driven by a cylinder, a motor, or other means. For details not described in this embodiment, please refer to Embodiment 1.
[0038] It should be noted that the sensor described in this invention may be, but is not limited to, a photoelectric sensor; the rotating roller, transmission belt, first air nozzle, second air nozzle, and groove described in this invention may be arranged in multiple ways along the length of the paper roll; the support platform described in this invention may not be a single flat plate, for example, it may be composed of multiple strips arranged at certain intervals; the rotating roller described in this invention is not limited to a single cylinder, for example, it may be composed of multiple coaxially mounted discs. The transmission belt described in this invention may be, but is not limited to, a belt.
[0039] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent protection scope. It should be pointed out that for ordinary skilled person in the art, without departing from the concept of the utility model, several modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
