The design of the device is not perfect, and there are mainly the following problems: 1) After the paper roll is cut into two parts by a cutter, since the paper layer part has a certain wrapping force on the core tube part, the paper layer part sometimes still adheres to the core tube part and cannot fall off from the core tube part as expected; 2) The paper roll cutting will generate a large amount of paper scraps, which are easy to accumulate on the guide rod and fill the gap between the core tube part and the guide rod, resulting in an increase in the movement resistance of the core tube part on the guide rod, and then causing the core tube part to move unsmoothly on the guide rod; 3) During the operation of the device, it is necessary to manually provide paper rolls to the device, which not only affects the work efficiency, but also consumes labor costs.

Figure 5 for Figure 2 Working principle diagram of the paper core separation mechanism for the middle roll paper. Figure 6 for Figure 2 A partial enlarged view of location B of the paper core separation mechanism for the middle roll paper. Figure 7 for Figure 1 Schematic diagram of the appearance structure of the paper core separation mechanism of the middle roll paper. Figure 2-Figure 7 As shown, the roll paper core separation mechanism 2 comprises: a roll paper feeding mechanism 21, a roll paper pushing mechanism 22, a roll paper cutting mechanism 23 and a core tube separation mechanism.

[0025] Among them, the paper roll feeding mechanism 21 is used to place the paper roll 4 to be separated from the paper core in a set manner on the paper roll support plate 211 so that the core barrel part 42 of the paper roll 4 is aligned with the front part of the guide rod 231 in the horizontal direction; the paper roll pushing mechanism 22 includes a reciprocating drive mechanism 221 and a push plate 222 connected to each other and is used to push the paper roll 4 located on the paper roll support plate 211 so that the core barrel part 42 is inserted into the guide rod 231; the paper roll cutting mechanism 23 includes a horizontally arranged guide rod 231 and a cutting device 232 located above the guide rod 231 and cutting the paper roll 4 inserted into the guide rod 231 in the horizontal direction; the core barrel separation mechanism is used to make the core barrel part 42 that moves to the rear of the guide rod 231 detach from the guide rod 231. The core tube separation mechanism specifically pushes the paper roll 4 from the head of the guide rod 231 along the guide rod 231 to the rear of the guide rod 231 continuously through the paper roll pushing mechanism 22 until the core tube part 42 of the paper roll 4 falls off from the rear of the guide rod 231, thereby achieving the detachment of the core tube part 42 that moves to the rear of the guide rod 231 from the guide rod 231.

[0026] In addition, the cutting device 232 includes a first cutting mechanism 233 and a second cutting mechanism 234 located at the rear side of the first cutting mechanism 233. During operation, the first cutting mechanism 233 first cuts the roll paper 4 located above the guide rod 231 into two halves, and then the second cutting mechanism 234 further expands the incision formed by the first cutting mechanism 233 laterally to cause the paper layer part 41 of the roll paper 4 to fall off the core tube part 42. During the above operation, the push plate 222, driven by the reciprocating drive mechanism 221, continuously pushes the roll paper 4 from the head of the guide rod 231 along the guide rod 231 to the rear of the guide rod 231.

[0027] The above-mentioned paper roll core separation mechanism, since the cutting device 232 includes a first cutting mechanism 233 and a second cutting mechanism 234 located at the side and rear of the first cutting mechanism 233, during the working process, the first cutting mechanism 233 first cuts the paper roll 4 located above the guide rod 231 into two pieces, and then the second cutting mechanism 234 further expands the incision formed by the first cutting mechanism 233 laterally to promote the paper layer part 41 of the paper roll 4 to fall off from the core tube part 42, thereby effectively solving the technical problem that the paper layer part cannot fall off in time after the paper roll is cut into two pieces. In addition, during the above-mentioned working process, the push plate 222 continuously pushes the paper roll 4 from the head of the guide rod 231 along the guide rod 231 to the rear of the guide rod 231 under the drive of the reciprocating drive mechanism 221, therefore, the push plate 222 continuously applies force to the paper roll 4 to move on the guide rod 231, thereby effectively solving the technical problem that the core tube part 42 does not move smoothly on the guide rod 231.

[0028] The specific structure and working principle of the roll paper feeding mechanism 21 are as follows: the roll paper 4 first moves forward in a single-layer flat posture on the transmission belt of the roll paper feeding mechanism 21, and a roll paper falling channel 212 is provided in front of the transmission belt (see Figure 3 ) so that the roll paper 4 running to the end of the transmission belt can fall from the transmission belt downward into the roll paper falling channel 212. The roll paper support plate 211 is just located at the bottom of the roll paper falling channel 212 to support the roll paper 4 falling into the roll paper falling channel 212. An inclined baffle 213 is provided at the end of the transmission belt (see Figure 2-Figure 3 ), the roll paper 4 that has run to the end of the transmission belt contacts the inclined baffle 213 and then rotates downward 90°. At this time, the roll paper 4 is adjusted from a flat posture to a sideways posture, and the roll paper falling channel 212 can maintain the sideways posture of the roll paper 4, so that the core tube part 42 is aligned with the front part of the guide rod 231 in the horizontal direction.

[0029] The specific structure and working principle of the roll paper pushing mechanism 22 are as follows: the reciprocating drive mechanism 221 adopts a belt transmission mechanism 223, which is mainly composed of a driving wheel, a driven wheel and a transmission belt connected between the driving wheel and the driven wheel. The driving wheel can rotate in both directions, so the transmission belt can move forward and backward. A push rod 224 is installed on the transmission belt, and the push rod 224 can be driven by the transmission belt to reciprocate forward and backward under the guidance of the guide mechanism. The push plate 222 is installed in front of the push rod 224. The reciprocating drive mechanism 221 is powered by the driving wheel of the belt transmission mechanism 223, so that the push plate 222 is driven to move forward and backward through the push rod 224. When the push plate 222 moves forward, the push plate 222 pushes the roll paper 4 on the roll paper support plate 211 so that the core barrel portion 42 is inserted into the guide rod 231. Thereafter, the push plate 222 continuously pushes the roll paper 4 from the head of the guide rod 231 along the guide rod 231 to the rear of the guide rod 231. Finally, the push plate 222 can be reset by reversing the driving wheel.

[0030] The above-mentioned reciprocating drive mechanism 221 can bring the following advantages in this application: 1) Controllable motion and stable thrust. The belt drive mechanism 223 uses a driving wheel to control the movement of the transmission belt, and the transmission belt drives the push rod 224 and the push plate 222 to move. Through the speed and steering control of the driving wheel, the propulsion speed, stroke and direction of the push plate 222 can be accurately adjusted, which is convenient for equipment debugging. At the same time, the transmission belt can provide stable and continuous thrust. 2) Simple structure and smooth transmission. Compared with other reciprocating drive forms such as hydraulic cylinders and cylinders, the structure of the belt drive mechanism is relatively simple, with low design and manufacturing difficulty and lower cost. The transmission belt moves smoothly and has low noise, which is very suitable for use in the paper roll paper core separation mechanism. 3) High transmission efficiency and easy maintenance. Belt drive has the advantages of high transmission efficiency and easy maintenance. The transmission belt and the driving wheel and the driven wheel are transmitted through friction, with high transmission efficiency, and the inspection, maintenance and replacement of the transmission belt are relatively convenient.

[0031] In a common embodiment, the first cutting mechanism 233 includes a blade rotation driving device and a rotating blade 233a installed on the rotating shaft of the blade rotation driving device, the rotating shaft is located above the guide rod 231 and is arranged perpendicular to the guide rod 231, and the surface of the guide rod 231 has an axial groove 231a for accommodating the blade of the rotating blade 233a. On this basis, the second cutting mechanism 234 includes a fixed blade 234a arranged at the rear side of the rotating blade 233a, and the cutting edge of the fixed blade 234a faces the front of the guide rod 231. The fixed blade 234a can be fixed on the mounting seat of the blade rotation driving device or the housing of the blade rotation driving device. The fixed blades 234a are usually two and distributed on both sides of the rotating blade 233a.

[0032] Furthermore, the cutting edge of the fixed blade 234a is an inclined cutting edge with the lower portion facing forward and the upper portion facing backward (eg Figure 3-Figure 4 As shown in the figure, the tip of the inclined blade is close to the upper surface of the guide rod 231 and the outer side of the rotating blade. After the blade of the fixed blade 234a is set to the above-mentioned inclined blade, the blade of the fixed blade 234a will gradually penetrate into the incision formed by the first cutting mechanism 233 as the roll paper 4 moves on the guide rod 231, so as to avoid the uneven width of the incision formed by the first cutting mechanism 233, which causes the blade of the fixed blade 234a to be unable to be fully inserted into the incision formed by the first cutting mechanism 233. In addition, since the inclined blade is set with the lower part forward and the upper part backward, the inclined blade first cuts into the central area of ​​the roll paper 4, and then gradually cuts into the upper edge area of ​​the roll paper 4, which is conducive to breaking the upper part of the roll paper 4 after the inclined blade cuts into the upper edge area of ​​the roll paper 4, so as to cause the paper layer part 41 of the roll paper 4 to fall off from the core tube part 42.

[0033] In addition, the guide rod 231 is provided with a material reduction groove 231b extending along the axial direction of the guide rod 231 at the lower side of the second cutting mechanism. When there are two fixed blades 234a and they are distributed on both sides of the rotating blade 233a, the guide rod 231 is provided with the material reduction groove 231b at the lower side of the two fixed blades 234a. Figure 4 As shown, in this embodiment, the cross section of the material reduction groove 231b is composed of a horizontal bottom surface and a vertical wall surface connected to the bottom surface. The combination of the horizontal bottom surface and the vertical wall surface is a relatively simple geometric structure, which can be processed by conventional processes such as milling and grinding, with high production efficiency and low processing cost.

[0034] The material reduction groove 231b is provided on the guide rod 231 mainly for the following functions: 1) Providing cutting space for the fixed blade 234a. The fixed blade 234a is located at the side and rear of the rotating blade 233a, and its cutting edge faces the front of the guide rod 231 and gradually cuts into the roll paper 4. The material reduction groove 231b extending along the axial direction is provided on the guide rod 231, which can provide space for the cutting edge of the fixed blade 234a to cut into the roll paper, avoiding the interference between the fixed blade 234a and the surface of the guide rod, which affects the cutting effect. 2) Reducing the contact area between the core barrel part 42 and the guide rod 231. The core barrel part 42 is sleeved on the guide rod 231 and moves along its axial direction. The material reduction groove 231b can reduce the contact area between the inner wall of the core barrel part 42 and the surface of the guide rod 231, thereby reducing the resistance of the core barrel part 42 to move on the guide rod 231, so that the core barrel part 42 can move forward more smoothly and improve the separation efficiency. 3) Avoid the influence of residual paper scraps. During the cutting process, the roll paper 4 will produce paper scraps, which are easy to adhere to the surface of the guide rod 231 and affect the advancement of the roll paper 4. The reduction groove 231b can collect some of the paper scraps in the groove, and then clean them up in a centralized manner to prevent the paper scraps from affecting the advancement of the roll paper 4. 4) It is convenient to install and adjust the fixed blade 234a. The reduction groove 231b is provided on the guide rod 231, which can facilitate the installation of the fixed blade 234a. By adjusting the position of the fixed blade 234a in the reduction groove 231b, the gap between the fixed blade 234a and the rotating blade 233a can also be fine-tuned to optimize the cutting effect.

[0035] like Figure 4 As shown, the upper part of the push plate 222 of the above-mentioned paper roll pushing mechanism 22 is provided with a first groove for accommodating the cutting part of the first cutting mechanism and the cutting part of the second cutting mechanism, and a second groove located at the bottom of the first groove and used to accommodate the guide rod, and a step structure adapted to the corresponding material reduction groove 231b is formed in the push plate 222 between the first groove and the second groove.

[0036] As a further improvement to the above scheme, Figure 6As shown, the core barrel separation mechanism also includes a compressed air blowing device 24, which is arranged on the push plate 222 and the nozzle 241 is arranged on the rear end surface of the step structure and tilted downward to point to the corresponding material reduction groove 231b. The compressed air blowing device 24 is arranged on the push plate 222, and its nozzle 241 is arranged on the rear end surface of the step structure and tilted downward to point to the corresponding material reduction groove 231b. When the roll paper 4 moves on the guide rod 231, the high-speed compressed air flow will blow to the cut of the roll paper 4, which can increase the opening angle of the cut on the one hand, and blow the peeled paper layer part 41 off the core barrel surface on the other hand. Under the dual effects of gravity and airflow, the paper layer part 41 will be separated from the core barrel part 42 faster and more thoroughly, thereby improving the paper core separation efficiency. The compressed air flow can also blow the paper scraps generated during the cutting process out of the material reduction groove 231b.

[0037] In addition, the core barrel separation mechanism may further include a paper core separation baffle 25 disposed at the lower rear portion of the guide rod 231, and the paper core separation baffle 25 is used to block the paper layer portion 41 from passing through and allow the core barrel portion 42 to pass through. The paper core separation baffle 25 disposed at the lower rear portion of the guide rod 231 can block the peeled paper layer portion 41 from continuing to move with the core barrel portion 42, and only allow the core barrel portion 42 to pass through. In this way, the paper layer portion 41 and the core barrel portion 42 are completely separated in front of the paper core separation baffle 25, and the core barrel portion 42 can smoothly pass through the paper core separation baffle 25 and be subsequently recycled, while the paper layer portion 41 will fall into the collection device under the blockage of the paper core separation baffle 25.

[0038] Figure 8 for Figure 1 Top view of the paper discharging mechanism for the middle roll. Figure 1 , Figure 8 As shown, the paper roll sorting and discharging mechanism 1 is used to lay out irregularly stacked paper rolls in a uniform and arranged manner for output, and comprises: a paper roll conveyor belt 11, a paper roll sorting roller 12 and a paper roll discharging baffle system 13.

[0039] The paper roll conveyor belt 11 is used to convey the paper roll 4 along the length direction, and the width of the paper roll conveyor belt 11 can simultaneously hold multiple rows of paper rolls 4; the paper roll material sorting roller 12 is installed above the paper roll conveyor belt 11 along the width direction of the paper roll conveyor belt 11 and is connected to a rotating drive mechanism, and a material sorting blade 121 is arranged along the paper roll material sorting roller 12, and the paper roll conveyor belt 11 forms a paper roll accumulation area and a paper roll discharge area in front and behind the paper roll material sorting roller 12 respectively, and the material sorting blade 121 is used to turn over the paper rolls whose height exceeds a set height among the paper rolls moving from the paper roll accumulation area to the paper roll discharge area so that these paper rolls pass through the paper roll material sorting roller in a single-layer flat posture; the paper roll discharge baffle system 13 is erected on the paper roll discharge area, so that the paper rolls on the paper roll discharge area are arranged and output in a set manner.

[0040] Specifically, the roll paper discharging baffle system 13 includes: a first roll paper discharging baffle 131 which is arranged in sequence according to the roll paper conveying direction, and the first roll paper discharging baffle 131 is used to gather multiple rows of roll paper in the roll paper discharging area into a first roll paper row; a roll paper height limiting guide rod 132, and the roll paper height limiting guide rod 132 is mounted at the first roll paper discharging outlet and is inclined to the roll paper conveying direction, and the roll paper height limiting guide rod is used to allow the roll paper with a height lower than the roll paper height limiting guide rod to pass through and guide the roll paper with a height higher than the roll paper height limiting guide rod to other directions; a second roll paper discharging baffle 133, and the second roll paper discharging baffle 133 is used to gather the roll paper passing through the roll paper height limiting guide rod into a second roll paper row; wherein, the setting height of the lower edge of the roll paper height limiting guide rod 132 is lower than the setting height of the lower edge of the roll paper sorting roller 12.

[0041] Furthermore, a guide roller 134 is provided at the edge of the first paper roll discharge outlet and is perpendicular to the paper roll placement plane of the paper roll conveyor belt.

[0042] The paper rolls in the paper roll stacking area are randomly and irregularly stacked. When these randomly and irregularly stacked paper rolls pass through the paper roll sorting roller 12, only the paper rolls placed in a single layer and flat posture can pass through the paper roll sorting roller, while the paper rolls placed in a flat posture with more than two layers and the paper rolls placed in a sideways posture will be turned over by the paper sorting blades because of their excessive height. In this way, it is ensured that the paper rolls pass through the paper roll sorting roller in a uniform single-layer flat posture; thereafter, these paper rolls placed in a single-layer flat posture are arranged and output by the paper roll discharge baffle system 13 in a set manner.

[0043] The above-mentioned paper roll sorting and discharging mechanism 1 is used to sort randomly stacked paper rolls into regularly arranged paper rolls and output them in a set manner. Its main advantages are as follows:

[0044] First, the paper roll posture is automatically corrected. The paper rolls are randomly placed in the paper roll stacking area, and may be placed flat, sideways, stacked, etc. By setting the paper roll sorting roller 12 and its sorting blade 121, the paper rolls that exceed the set height can be turned over to restore them to a single-layer flat posture. This process utilizes the center of gravity characteristics of the paper roll, and through external force disturbance, it naturally tends to a stable flat state, thereby realizing the automatic correction of the paper roll posture without manual intervention.

[0045] Second, improve the regularity of paper roll arrangement. After being processed by the paper roll sorting roller 12, the paper roll enters the paper roll discharging area in a single-layer flat posture. In the paper roll discharging area, the scattered paper rolls can be gathered into a regular paper roll row through the action of the paper roll discharging baffle system 13. Among them, the first baffle 131 of the paper roll discharging can gather multiple rows of paper rolls into one row, the paper roll height limiting guide rod 132 can remove over-high paper rolls, and the second baffle 133 of the paper roll discharging can gather the paper rolls again. Through this series of operations, the neatness and regularity of the paper roll arrangement can be ensured, which is convenient for subsequent transportation.

[0046] Third, the smoothness of paper roll conveying is increased. A guide roller 134 perpendicular to the conveyor belt plane is set at the edge of the first paper roll discharge outlet to play a supporting and guiding role. When the paper roll enters the paper roll height limiting guide rod 132 from the first discharge area, the guide roller 134 can reduce the friction between the paper roll and the outlet edge, allowing the paper roll to pass smoothly and avoid affecting the regularity of arrangement due to falling or jamming. At the same time, the guide roller 134 can also control the feeding speed of the paper roll to prevent the paper roll from being scattered and flying under the action of inertia, further improving the smoothness of paper roll conveying.

[0047] The above is a description of the relevant contents of the present invention. A person skilled in the art will be able to implement the present invention based on these descriptions. Based on the above contents of this specification, all other embodiments obtained by a person skilled in the art without making creative work should fall within the scope of the present invention.
