Description

Technical Field

[0001] The invention relates to the technical field of cardboard processing, in particular to an automatic cardboard stripping device. Background Art

[0002] Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into single-corrugated cardboard and double-corrugated cardboard. Corrugated paper has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and easy storage and transportation. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0003] When making packaging boxes with corrugated paper, the corrugated paper needs to be folded into the required shape. However, during use, due to wear and tear or force during transportation, the folds of the corrugated paper are prone to cracking, resulting in the packaged products being exposed, which is not conducive to transportation and sales. Summary of the Invention

[0004] In order to solve the problem that corrugated paper is easily broken at the folds, the present application provides an automatic cardboard stripping device.

[0005] The above-mentioned invention object of the present invention is achieved through the following technical solutions: a cardboard automatic stripping device, comprising

[0006] Bracket,

[0007] The roller is rotatably mounted on the bracket and is used to support and transport the cardboard;

[0008] A turret is rotatably connected to the bracket, the turret is located on the upstream side of the roller conveying the paperboard, and the rotation axis of the turret is parallel to the rotation axis of the roller;

[0009] A tape roller is rotatably connected to the rotating frame, the tape is fixed on the tape roller, and the rotation axis of the tape roller is parallel to the rotation axis of the supporting roller; and

[0010] The first fixing member is used to fix the rotating frame and the bracket relative to each other.

[0011] By adopting the above technical solution, the cardboard is supported and conveyed by the rollers, and the tape on the tape roller is adhered to the fold of the cardboard. As the cardboard is conveyed, the tape will be pulled and adhered to the cardboard, and the tape roller will be driven to rotate at this time; the distance between the tape roller and the cardboard can be adjusted by the rotating frame, thereby changing the pulling angle between the free end of the tape and the tape roll when the tape is pulled out, and the pulling force required for unwinding the tape can be changed. At the same time, the noise generated when the tape is pulled can also be adjusted, and the position of the tape roller can be adjusted according to actual conditions. By sticking the tape on the fold of the cardboard, the fold of the cardboard can be strengthened, making the fold less likely to break.

[0012] Preferably, a pressing roller is further included, and the pressing roller is located above the supporting roller and is used to press the cardboard onto the supporting roller.

[0013] By adopting the above technical solution, the adhesive tape attached to the cardboard can be pressed tightly against the cardboard by the pressing roller, thereby preventing the adhesive tape and the cardboard from delaminating during subsequent use.

[0014] Preferably, the pressure roller includes a plurality of pressure wheels, which are evenly distributed along the rotation axis of the roller, and accommodating gaps are formed between adjacent pressure wheels.

[0015] By adopting the above technical solution, since there may be bulges or depressions at the creases, when the tape is pressed against the cardboard, the creases may be crushed or the tape may not be completely pressed against the cardboard. By pressing the pressing wheels on both sides of the creases, the creases are just located within the accommodating gaps. In this way, the tape can be pressed tightly against the cardboard without damaging the creases on the cardboard.

[0016] Preferably, at least two tape rollers are provided, and the tape rollers are distributed on the rotating frame in a circle with the rotating center of the rotating frame as the center of the circle.

[0017] By adopting the above technical solution, the tape on the tape roller needs to be replaced with a new tape after it is used up. By using at least two tape rollers, multiple tapes can be installed at one time. When one roll of tape is used up, the rotating frame is immediately rotated so that the other tape can be quickly connected, reducing the time loss when changing the tape and improving production efficiency.

[0018] Preferably, the rotating frame is provided with:

[0019] A movable frame, wherein the movable frame is rotatably connected to the turret with the rotation center of the turret as a rotation axis, and the tape roller is rotatably connected to the movable frame;

[0020] A first magnetic member is located on the movable frame; and

[0021] a second magnetic member located on the rotating frame, the second magnetic member being configured to be attracted to the first magnetic member, and the first magnetic member being separated from the second magnetic member when the force acting on the first magnetic member and the second magnetic member exceeds a specified value;

[0022] The bracket is rotatably provided with:

[0023] A pre-tensioning frame, movably connected to the bracket, wherein the pre-tensioning frame is provided with a support member, the support member is used to place and support the free end of the tape on the tape roller, and when the movable frame rotates, the tape roller can be in contact with the support member; and

[0024] The second fixing piece is used to fix the pre-tensioning frame to the bracket.

[0025] By adopting the above technical solution, the end of an unused roll of tape on the tape roll is pulled apart and placed on the support. At this time, the adhesive surface of the tape will face away from the support. When the tape on the tape roll in use is used up, due to the relatively large adhesion force between the tape and the tape roll, the movable frame will be pulled to separate the first magnetic member and the second magnetic member. At this time, the movable frame will rotate to make the tape roll fit the support. At this time, the tape on the support will be adhered to the tape on the used tape roll, and then as the cardboard is conveyed, the used tape is separated from the tape roll. Since the new tape is adhered to the end of the previous roll of used tape, the new tape will be pulled and the new tape roll will rotate, so that the new tape is continuously unwound and adhered to the cardboard, completing the automatic tape replacement.

[0026] Preferably, the rotating frame is located below the roller, and the supporting member includes:

[0027] An articulated frame is rotatably connected to the pre-tensioned frame, and the rotation axis of the articulated frame is parallel to the rotation axis of the movable frame;

[0028] A first supporting roller is rotatably connected to the articulated frame, and a rotation axis of the first supporting roller is parallel to a rotation axis of the supporting roller;

[0029] The second support roller is rotatably connected to the articulated frame, and the rotation axis of the second support roller is parallel to the rotation axis of the supporting roller. The first support roller is located on one side of the rotation axis of the articulated frame, and the second support roller is located on the other side of the rotation axis of the articulated frame. The distance between the second support roller and the rotation axis of the articulated frame is not less than the distance between the first support roller and the rotation axis of the articulated frame. The second support roller is located on the side of the articulated frame away from the supporting roller.

[0030] By adopting the above technical solution, the end of the new tape can be pressed against the end of the tape to be used by the first supporting roller and the second supporting roller, thereby completing the replacement of the tape.

[0031] Preferably, when the movable frame rotates, the tape roller can fit with the second support roller, and the articulated frame is provided with an elastic member at the end of the second support roller, and the elastic member is located between the articulated frame and the pre-tensioning frame. When the tape roller 4 contacts the second support roller, the articulated frame rotates, the elastic member will be compressed, and the first support roller will fit with the tape roller.

[0032] By adopting the above technical solution, when the tape roller is in contact with the second support roller, the tape roller will push the second support roller to rotate the hinged frame, thereby allowing the first support roller to gradually approach the tape roller and contact the tape roller. At this time, the tapes on the first support roller and the second support roller will be pressed tightly and adhered to the tape on the tape roller. When the tape is replaced, it is not easy for the new tape to stick to the previous roll of used tape.

[0033] Preferably, the articulated frame is detachably provided with a cutter on the side of the second support roller. When the movable frame rotates, the tape roller can be fitted with the first support roller. When the first support roller contacts the tape wheel, it can push the articulated frame to rotate and allow the blade of the cutter to contact the tape wheel. A passage for the tape to pass through is provided between the cutter and the articulated frame.

[0034] By adopting the above technical solution, when the tape roll is in contact with the first support roller, the tape roll will push the first support roller to rotate the hinged frame, thereby allowing the second support roller to gradually approach the tape roll, and at the same time, the cutter will gradually approach the tape roll and contact the tape roll, so that the tape on the tape roll that is about to be used up is cut off. At the same time, the tape on the first support roller and the second support roller will be pressed tightly and adhered to the tape on the tape roll. When the tape that is about to be used up is cut off, the new tape has been attached to the old tape, and the new tape can be directly transitioned to use, avoiding the deformation of the tape when the tape is pulled off the tape roll, resulting in the tape becoming narrower and having a poor cardboard protection effect. The tape that is about to be used up can be directly cut off by the cutter.

[0035] Preferably, the first magnetic member includes a fitting surface for being attracted to the second magnetic member, and a buffer pad is provided on the fitting surface.

[0036] By adopting the above technical solution, a buffering effect can be achieved when the first magnetic part and the second magnetic part are attracted to each other, thereby avoiding damage after the two collide. At the same time, the size of the attraction force between the first magnetic part and the second magnetic part can be adjusted by the thickness of the buffer pad, so that the tape can pull the movable frame to rotate when needed.

[0037] Preferably, there are multiple rotating racks distributed along the rotation axis of the roller.

[0038] By adopting the above technical solution, multiple folds on the cardboard can be used for reinforcement.

[0039] In summary, the present invention includes at least one of the following beneficial technical effects:

[0040] 1. By sticking tape on the crease of the cardboard, the cardboard can be strengthened at the crease after folding, making it less likely to break at the crease;

[0041] 2. During use, multiple rolls of tape can be kept in reserve, and the next roll of tape can be quickly replaced after the previous roll is used up, which increases production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The present invention will be further described in detail below with reference to the accompanying drawings.

[0051] Example 1:

[0052] Reference Figure 1 、 2 , which is an automatic cardboard stripping device disclosed by the present invention, includes a bracket 1, a roller 2 and a rotating frame 3. The roller 2 and the rotating frame 3 are both rotatably connected to the bracket 1. The rotation axes of the roller 2 and the rotating frame 3 are parallel. The top of the roller 2 is used to place the cardboard. When the roller 2 rotates, it can drive the cardboard to be transported. A pressure roller 6 is also provided above the roller 2. The pressure roller 6 is also rotatably fixed on the bracket 1. The cardboard passes between the pressure roller 6 and the roller 2. In use, cardboards of different thicknesses can be transported by changing the distance between the roller 2 and the pressure roller 6.

[0053] Among them, the pressing roller 6 includes several pressing wheels 61, and there are several pressing wheels 61 distributed along the axial direction of the roller 2. An accommodating gap 62 is formed between adjacent pressing wheels 61. When the cardboard passes between the pressing roller 6 and the roller 2, the position of the cardboard is adjusted so that the fold position on the cardboard is exactly at the accommodating gap 62.

[0054] Reference Figure 1 、 2In this embodiment, the rotating frame 3 is located on the bracket 1 below the roller 2. A movable frame 7 is rotatably connected to the rotating frame 3. The movable frame 7 rotates coaxially with the rotating frame 3. The number of rotating frames 3 can be adjusted according to the number of folds on the cardboard. In this embodiment, there are two rotating frames 3, which are spaced apart along the axial direction of the roller 2. A first fixing member 5 is provided between the bracket 1 and the rotating frame 3. The first fixing member 5 can be used to fix the rotating frame 3 to the bracket 1, so that the rotating frame 3 cannot rotate. In this embodiment, the first fixing member 5 is a bolt, which is threadedly connected to the bracket 1. When the bolt is rotated, it can be tightened against the rotating frame 3, thereby fixing the rotating frame 3. Turning the bolt to separate the bolt from the rotating frame 3 allows the rotating frame 3 to rotate again.

[0055] Among them, the movable frame 7 is rotatably connected to the tape roller 4. In this embodiment, there are three tape rollers 4, which are evenly distributed on the movable frame 7 around the rotation center axis of the movable frame 7. The rotation axis of the tape roller 4 is parallel to the rotation axis of the roller 2. During use, the tape is fixed to the tape roller 4. When the end of the tape is pulled, the tape roller 4 will drive the tape to rotate, thereby unwinding the tape. When the tape needs to be adhered to the cardboard, the worker will lead the end of the tape from one of the tape rollers 4 and apply it to the cardboard. When the cardboard drives the tape through the space between the roller 2 and the pressure roller 6, the tape is pressed tightly against the cardboard, completing the continuous taping work.

[0056] In the initial state, if Figure 1 As shown, one of the tape rollers 4 is located at the top, while the other two tape rollers 4 are located at the left and right sides of the bottom. When in use, the tape on the upper tape roller 4 is first pulled and stuck to the cardboard. As the cardboard is conveyed, the tape on the upper tape roller 4 will be gradually used; and the tapes on the other two tape rollers 4 are reserved so that they can be quickly replaced when the tape on the upper tape roller 4 is used up.

[0057] Reference Figure 3 、 4In order to achieve the purpose of automatically replacing the tape on the lower left tape roller 4 after the tape on the upper tape roller 4 is used, a first magnetic member 8 is provided on the movable frame 7, and a second magnetic member 9 is provided on the rotating frame 3. In use, the first magnetic member 8 is located above the second magnetic member 9. The first magnetic member 8 and the second magnetic member 9 can attract each other when they are close to each other. When the movable frame 7 is rotated, the first magnetic member 8 and the second magnetic member 9 are attached and attracted together; wherein, the first magnetic member 8 includes a bonding surface 81. When the first magnetic member 8 and the second magnetic member 9 are attracted, the bonding surface 81 is located between the first magnetic member 8 and the second magnetic member 9. In order to avoid excessive impact force during the attraction process of the first magnetic member 8 and the second magnetic member 9, a buffer pad 14 is provided on the bonding surface 81. The buffer pad 14 is a rubber pad. By adjusting the thickness of the buffer pad 14, the size of the attraction force between the first magnetic member 8 and the second magnetic member 9 can be adjusted. In this embodiment, the first magnetic member 8 and the second magnetic member 9 are permanent magnets.

[0058] Reference Figure 2 、 3 At the same time, a pre-tensioned frame 10 is rotatably mounted on the bracket 1. A support member 11 is mounted on the pre-tensioned frame 10. The pre-tensioned frame 10 is rotatably connected to the bracket 1, and a second fixing member 12 is disposed between the pre-tensioned frame 10 and the bracket 1. The position of the pre-tensioned frame 10 can be adjusted by the second fixing member 12, thereby changing the relative position between the support member 11 and the tape roller 4. In this embodiment, the pre-tensioned frame 10 is located on the bracket 1 between the roller 2 and the movable frame 7. The pre-tensioned frame 10 is hinged to the bracket 1, and the second fixing member 12 is a bolt located between the pre-tensioned frame 10 and the bracket 1. When the position of the pre-tensioned frame 10 needs to be adjusted, the bolt is loosened for adjustment. After adjustment, the pre-tensioned frame 10 can be fixed by tightening the bolt.

[0059] Reference Figure 2 、 3 , wherein the support member 11 includes an articulated frame 111, a first support roller 112 and a second support roller 113. The first support roller 112 is rotatably connected to one end of the articulated frame 111, and the second support roller 113 is rotatably connected to the other end of the articulated frame 111. The articulated frame 111 is hinged on the pre-tensioned frame 10, and the distance from the articulated frame 111 to the pre-tensioned frame 10 at the hinge point is the same as the distance from the first support roller 112 and the second support roller 113, that is, the middle part of the articulated frame 111 is articulated to the pre-tensioned frame 10, and the rotation axis of the first support roller 112 and the second support roller 113 is parallel to the rotation axis of the roller 2.

[0060] During use, the second support roller 113 is located close to the rotating frame 3, and the first support roller 112 is located away from the rotating frame 3, and then the tape on the lower left tape roller 4 is pulled and placed on the first support roller 112 and the second support roller 113. At this time, under the action of the gravity of the tape, the horizontal height of the second support roller 113 is smaller than the horizontal height of the first support roller 112, so that the adhesive surface of the tape on the first support roller 112 and the second support roller 113 faces upward.

[0061] Reference Figure 2 、 3 An elastic member 16 is connected between the articulated frame 111 and the pre-tensioned frame 10. The elastic member 16 is a spring. One end of the elastic member 16 is connected to the pre-tensioned frame 10, and the other end of the elastic member 16 is connected to the articulated frame 111. The elastic member 16 makes the height of the second support roller 113 smaller than the height of the first support roller 112 and keeps it in a fixed position. The elastic member 16 can support the second support roller 113 in a suitable position.

[0062] When the adhesive tape on the upper tape roller 4 is used up, the adhesive tape between the adhesive tape and the tape roller 4 is larger, and thus the movable frame 7 is subjected to a rotational force greater than the magnetic force between the first magnetic member 8 and the second magnetic member 9, so that the movable frame 7 breaks away from the fixation of the first magnetic member 8 and the second magnetic member 9 and rotates counterclockwise. Due to the effect of inertia, the upper tape roller 4 hits the second support roller 113. At this time, the second support roller 113 drives the hinged frame 111 to rotate and press the elastic member 16. At the same time, the adhesive tape on the second support roller 113 will stick to the adhesive tape on the upper tape roller 4; and when the hinged frame 111 rotates, the first support roller 112 will drive the adhesive tape to adhere to the adhesive tape pulled out from the upper tape roller 4, and finally make the adhesive tape on the first support roller 112 stick to the adhesive tape on the upper tape roller 4. With the transmission of the cardboard, the adhesive tape will be pulled and gradually drive the adhesive tape on the lower left tape roller 4 to gradually unwind. During this process, the tape on the upper tape roller 4 will be used up and stop rotating, so that the end of the tape on the upper tape roller 4 and the head of the tape on the lower left tape roller 4 are automatically connected, thereby completing the purpose of automatically replacing the tape.

[0063] The worker can adjust the position of the rotating frame 3 according to the time and replenish the tape. After the tape is automatically replaced, the worker needs to allow the first magnetic member 8 and the second magnetic member 9 to attract each other, then release the first fixing member 5, and then rotate the rotating frame 3 counterclockwise so that the tape roller 4 at the lower left rotates to the upper position, and the tape roller 4 at the lower right rotates to the lower left, and the upper tape roller 4 rotates to the lower right. Then, the rotating frame 3 is fixed by the first fixing member 5 so that the rotating frame 3 no longer rotates, and then the new tape is replenished at the lower right position, and the tape is pulled out from the lower left tape roller 4 and placed on the first support roller 112 and the second support roller 113, so as to prepare for the next automatic replacement of the tape. By allowing the tape to be replaced automatically, the time interval for workers to replace the tape can be extended, and the labor intensity of workers can be reduced.

[0064] Example 2:

[0065] Reference Figure 5 、 6 , a cardboard automatic stripping device, the difference from the embodiment 1 is that the hinge frame 111 is located on the side of the second support roller 113 and is detachably provided with a cutter 13, and a through hole 15 for the tape to pass through is provided between the cutter 13 and the hinge frame 111 (refer to Figure 7 ), and no elastic member 16 is provided between the articulated frame 111 and the pre-tensioned frame 10. Before use, the position of the pre-tensioned frame 10 is adjusted so that the pre-tensioned frame 10 is tilted and the second support roller 113 is placed above the first support roller 112. During use, the tape on the tape roller 4 on the lower left is pulled through the through-hole 15 and placed on the first support roller 112 and the second support roller 113.

[0066] When the tape on the upper tape roll 4 is exhausted and the movable frame 7 is rotated, the tape roll 4 will collide with the first support roller 112. At this time, the first support roller 112 will drive the tape on the lower left tape roll 4 to fit the tape on the upper tape roll 4. At the same time, it will push the hinge frame 111 to rotate. The hinge frame 111 will drive the second support roller 113 and the cutter 13 to move to the upper right until the cutter 13 first contacts the upper tape roll 4 and cuts the tape on the tape roll 4. At the same time, the second support roller 113 will then drive the tape on the lower left tape roll 4 to fit the cut tape, thus completing the tape joint replacement work. During this process, the tape on the upper tape roll 4 is directly cut, thereby avoiding the situation where the end of the tape on the upper tape roll 4 is stretched and thinned during the process of tearing off the tape on the upper tape roll 4, and can also prevent the tape with changed quality from being attached to the cardboard.

[0067] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
