[0041] Example

[0042] Snow pear paper, also known as copy paper, was named snow pear paper because it was usually used to pack snow pears in the beginning. Snow pear paper is a high-grade cultural industrial paper with high production difficulty. The product has high physical strength, excellent uniformity and transparency, and good surface properties. It is delicate, flat, smooth, free of bubble sand, and has good printability. Up to now, the use of snow pear paper has been very wide, and it can be used for fruit packaging, clothing, shoes, hardware packaging, craft packaging, seal carving art, etc.

[0043] In the battery production process, pear paper can also play an important role. For example, when cutting electrode sheets, it can be placed between the cut electrode sheets to facilitate the subsequent separation of the two electrode sheets from the position of the pear paper.

[0044] When using pear paper, you need to tear it off manually for later use. It is easy to tear the pear paper off-center if you tear it directly. If you use a knife to cut it, or fold it in half and then tear it along the crease, the tearing speed is slower and there is also a risk of tearing it off-center.

[0045] This embodiment provides a snow pear paper cutting device, such as Figure 1-6 As shown,

[0046] A Sydney paper cutting device, characterized in that it comprises a bracket 1, a placement shaft 2, a clamping rod, a pedal device, a sliding connecting rod 5, a cutting knife 6 and a support plate 7, wherein the placement shaft 2 is fixedly arranged on the bracket 1, and two ends of the clamping rod are respectively connected to two sliding connecting rods 5;

[0047] The support plate 7 is fixedly arranged on the bracket 1, and the support plate 7 is arranged close to the clamping rod, and there is a gap between the support plate 7 for the snow pear paper to pass through;

[0048] Furthermore, the side of the clamping rod close to the support plate is in an arc shape;

[0049] The cutting knife 6 is fixedly mounted on the bracket 1 and is arranged in front of the side of the support plate 7 facing the clamping rod. The snow pear paper passes through between the clamping rod and the support plate 7 and then passes through the cutting knife 6 area for cutting.

[0050] Sliding sleeves 8 are respectively provided on both sides of the bracket 1, and the sliding connecting rod 5 is arranged in the sliding sleeve 8 and is slidably connected to the bracket 1. The sliding connecting rod abuts against the bracket 1 through a first spring 11, and the first spring 11 pushes the clamping rod away from the support plate 7;

[0051] The pedal device is fixedly connected to one end of the two sliding connecting rods 5 away from the clamping rod.

[0052] The Sydney paper roll sleeve is arranged on the placement shaft 2, and the paper goes around the clamping rod and extends to the cutting knife 6. The cutting length is controlled by dragging the paper. After determining the cutting length, the worker steps on the pedal device. Since the pedal device is fixedly connected to the sliding connecting rod 5, the pedal device 4 will drive the sliding connecting rod 5 to move downward. The first spring 11 is in a compressed state, and the sliding connecting rod 5 drives the clamping rod to move downward until the roller 3 abuts the support plate 7, and the side of the clamping rod close to the support plate is set in an arc shape to avoid scratching the Sydney paper. At this time, the paper is pressed on the support plate 7 by the clamping rod and cannot move. The worker holds the end of the paper to be cut, places the cutting surface on the cutting knife 5, drags it downward to complete the cutting operation, and then releases the foot to start the next cutting. The whole process is convenient to operate, and there is no need to manually hold the two ends of the paper for cutting. The worker only needs to repeat the three actions of dragging-stepping on the pedal-cutting to complete the Sydney paper cutting operation, and the cutting part is horizontal and uniform, and the process is simple.

[0053] As an optional embodiment, the pedaling device is a pedal rod 41 , both ends of which are fixedly connected to the sliding connecting rods 5 on both sides, and the worker can step on the pedal rod with one foot to achieve the abutment between the clamping rod and the support plate 7 .

[0054] As an optional embodiment, the pedaling device further includes a pedal 4, one end of which is overlapped on a side of the pedal rod close to the clamping rod, and the other end of the pedal is hinged to the bottom of the bracket.

[0055] When in use, the worker steps on the pedal 4 to achieve the rotation movement of the pedal 4, thereby driving the sliding connecting rod 5 to move downward, and then achieving the abutment between the clamping rod and the support plate 7. Compared with the method of directly stepping on the pedal rod 41, the pedal has a larger area and the foot can be placed at any position of the pedal 4. There is no need to find the position of the pedal rod 41 when stepping on it. The following embodiments are further described by taking the pedal 4 as an example.

[0056] Preferably, the clamping rod is a roller 3, and the roller 3 is rotationally connected to the sliding connecting rod 5. When the paper passes around the roller 3 and the paper is pulled, the roller 3 continues to rotate to reduce the friction between the roller 3 and the paper, further avoiding damage to the snow pear paper. The following embodiments are further described by taking the roller 3 as an example.

[0057] Preferably, the placement shaft 2 also includes a fixed baffle 21 and a movable baffle 9, the fixed baffle is fixedly sleeved on the placement shaft 2, the movable baffle 9 is sleeved on the placement shaft 2 and fixed by bolts, and the position for placing snow pear paper is between the fixed baffle 21 and the movable baffle 9.

[0058] An adjustable snow pear paper placement position is formed between the movable baffle plate 9 and the fixed baffle plate 21 for clamping snow pear paper rolls of different widths.

[0059] Preferably, the cutting knife 6 has cutting teeth, and when the snow pear paper is pulled down, the cutting teeth are more convenient to pierce the snow pear paper, so as to cut accurately and quickly.

[0060] Preferably, a strip mesh support 10 is provided between the cutting knife 6 and the support plate 7, and the setting direction of the strip groove of the strip mesh support 10 is parallel to the length direction of the clamping rod. Thinner snow pear paper is easily adsorbed on the flat support plate and is difficult to pick up. When the cutting operation is completed once, the remaining part of the paper to be cut can be freely carried on the strip mesh support 10, avoiding the workers to use their hands to find the flat support plate to pick up the head of the snow pear paper every time the operation is restarted. The groove opened parallel to the length direction of the roller is perpendicular to the pulling direction of the snow pear paper. After the finger passes through the strip groove, it can move in the length direction of the strip groove to enter the bottom of the snow pear paper and quickly grab the snow pear paper.

[0061] Preferably, the strip mesh support 10 has an arc surface, which is arched toward the top of the bracket and parallel to the length direction of the clamping rod. Compared with a flat support, when a finger is inserted into the arc support, the angle between the finger and the support surface is closer to 90 degrees, so that the strip mesh support 10 with an arc surface is easier for workers to pass through, and it is more convenient to clamp paper.

[0062] Preferably, the sliding connecting rod 5 of the bracket 1 includes a accommodating cavity 12 fixed at the top thereof, a slider 13 and a slide groove are provided in the accommodating cavity 12, and the slider 13 can slide in the slide groove;

[0063] The roller 3 is provided with bearings at both ends, and is rotatably connected to the slider 13 through the bearings;

[0064] Two anti-skid columns 15 are arranged on the sliding link 5 , and the anti-skid columns 15 can move with the sliding link 5 to contact the surface of the roller to limit the rotation of the roller.

[0065] When the roller 4 is in contact with the support plate 7, the absolute position of the roller 4 is fixed and locked. The downward force on the pedal 4 is continued, and the sliding link 5 will drive the accommodating chamber 12 to continue to move downward. At this time, the movement of the slider 13 in the slide groove relative to the accommodating chamber 12 is upward, and the accommodating chamber 12 continues to move downward until the two anti-skid columns 15 abut and lock the roller 3, so that the roller 3 can no longer rotate. At this time, the paper and the roller 3 will be completely locked during the cutting operation; because the roller 3 is rotatable, even if the roller 3 is abutted and locked with the support plate 7, it is inevitable that the roller 3 will be driven to rotate during cutting due to the force applied to drag the paper. The design of this preferred embodiment further locks the rotational freedom of the roller when the roller 3 abuts with the support plate 7 to avoid the movement of the paper during cutting.

[0066] Furthermore, a second spring 14 is provided between the slider 13 and the top of the inner cavity of the accommodating cavity 12 , and the second spring 14 pushes the slider 13 to a side close to the supporting plate 7 .

[0067] The sliding setting of the slider in the accommodating cavity realizes the locking of the roller through the anti-skid column. However, when the roller and the support plate are initially in contact, the sliding of the slider cannot immediately provide pressure to the support plate. The anti-skid column needs to abut against the surface of the roller to transmit the downward pressure of the sliding link to the roller to limit the rotation of the roller. There is a delay from the initiation of the pedaling action to the clamping response, which cannot be clamped in time and also affects the cut length.

[0068] In this solution, the second spring pushes the slider toward one side of the support plate, that is, pushes the roller toward one side of the support plate, so that when the roller contacts the support plate, the sliding link that continues to press downward can transmit a certain force to the roller to press against the support plate to initially clamp the snow pear paper. When the downward pressure continues, the sliding link continues to move, compressing the second spring until the anti-slip bar contacts the roller and locks the roller.

[0069] When a technician in this field or an operator implements the specific implementation, first, the snow pear paper roll is placed on the placement shaft 1 and fixed, one end of the snow pear paper is extended, passed around the roller 3 and overlapped on the cutting knife 6, the cutting length is determined, and the pedal 4 is pressed. Driven by the downward movement of the sliding connecting rod 5, the roller 3 is driven to abut against the support plate 7, and further pressure is applied to the pedal 4, so that the anti-skid column 15 on the accommodating cavity 12 locks the rotational freedom of the roller 3, and the paper is completely fixed. At this time, the snow pear paper is held and dragged and pressed downward to complete the cutting. After the cutting is completed, the pedal 4 is released and the above operation is repeated. The whole process can be completed by one person, and the operation is convenient and the cutting is accurate.

[0070] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
