Description

Technical Field

[0001] The utility model relates to the technical field of paper separators, and in particular to a paper separator used for producing paper corner protectors. Background Art

[0002] Paper corner protector, also known as edge protector, is a kind of packaging material, which is mainly used to protect the edges and corners of goods from being damaged during transportation and storage. It is usually made of kraft paper, corrugated cardboard or other high-strength paper materials, with good compression resistance and impact resistance. The use of paper corner protector can effectively prevent damage caused by collision during transportation of goods, and improve the safety and integrity of goods.

[0003] Paper corner protectors are usually made of multiple rolls of paper strips pressed together during production, and finally formed into a whole long strip, which needs to be cut into different lengths for easy use. However, in the current production line, the length of the cut is usually controlled by controlling the time when the cutter falls. In actual production, multiple tests are required to confirm the length of the cut, which will cause material waste and increase production costs. Utility Model Content

[0004] The utility model provides a paper splitter for the production of paper corner protectors, which solves the problem that the method of controlling the cutting length by controlling the falling time of the cutter in the related technology requires multiple tests to confirm the final cutting length in actual production, which causes material waste during the test and debugging period and increases the production cost.

[0005] The technical solution of the utility model is as follows:

[0006] A paper splitter for producing paper corner protectors, used for cutting off a whole piece of pressed paper corner protectors, comprising:

[0007] A support, wherein the support has a working surface;

[0009] A cutter is lifted and arranged on the bracket, and the cutter enters or leaves the cutting slot after being lifted and lowered;

[0010] A stopper, slidably disposed in the cutting slit, and used to close or open the cutting slit after the stopper slides;

[0011] A protection block is arranged on a side of the cutter close to the carrying roller, and after the stopper closes the cutting slit and the cutter descends, the protection block abuts against the stopper.

[0012] Optionally, the bearing roller is shuttle-shaped, and has a plane and an inclined surface, the inclined surface is used to receive the paper corner protector, and the cutting seam is located on the plane and the inclined surface.

[0013] Optionally, the carrying roller has a plurality of mounting grooves, and further comprises:

[0014] There are several mounting blocks, which are slidably arranged on the stopper. After the stopper slides, it enters or leaves the mounting groove. After the mounting block enters the mounting groove, the mounting block restricts the stopper from sliding in the cutting slot.

[0015] Optionally, it also includes:

[0016] The first rotating driving member is arranged on the bracket, and the first rotating driving member has a first driving end, and the first driving end is connected to the bearing roller, and the first rotating driving member is used to drive the bearing roller to rotate.

[0017] Optionally, also include:

[0018] The first telescopic member is arranged on the bracket, the first telescopic member has a first telescopic end, the first telescopic end is connected to the cutter, and the first telescopic member is used to drive the cutter to rise and fall.

[0026] In the utility model, the bracket is used to bear the weight of other components and paper corner guards on the paper separator to ensure that the paper separator can operate accurately. The bearing roller is used to bear the paper corner guard to ensure the stability of the conveying of a whole piece of paper corner guard that has been pressed. When the cutter descends, the cutter will gradually enter the cutting slit. At this time, the paper corner guard located on the bearing roller will be cut by the cutter. Since the gap of the cutting slit is similar to the thickness of the cutter, the paper corner guard will still be carried by the bearing roller during cutting, thereby ensuring the flatness of the cutting surface and improving the quality of the product. The stopper is arranged in the cutting slit to close the cutting slit. When the cutting slit is closed, after the cutter falls, since the position of the protection block is higher than the cutter, the protection block will first contact the stopper to prevent the cutter from further descending. At this time, the paper corner guard will not be cut. The protection block can not only prevent the paper corner guard from being cut, but also prevent the cutter from directly contacting the stopper, thereby ensuring the sharpness of the cutter blade and improving the quality of the product and the service life of the entire equipment. When cutting, by controlling whether there are blocks at different positions to close the cutting seam, the paper corner protector can be cut into different lengths while keeping the cutting speed unchanged, and precise control of the length can be achieved without any other debugging of the equipment.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0034] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0035] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes a paper splitter for the production of paper corner protectors, which is used to cut off the entire pressed paper corner protector, including a support 1 with a working surface 110; a supporting roller 2 is rotatably set on the support 1, and the side wall of the supporting roller 2 abuts against the paper corner protector, and the supporting roller 2 has a plurality of cutting slits 210, and the plurality of cutting slits 210 are circumferentially spaced on the supporting roller 2; a cutter 3 is lifted and set on the support 1, and the cutter 3 enters or leaves the cutting slit 210 after being lifted and lowered; a stopper 220 is slidably set in the cutting slit 210, and the stopper 220 is used to close or open the cutting slit 210 after sliding; a protective block 310 is set on the side of the cutter 3 close to the supporting roller 2, and the stopper 220 closes the cutting slit 210 and after the cutter 3 is lowered, the protective block 310 abuts against the stopper 220.

[0037] In this embodiment, the bracket 1 is used to bear the weight of other components and paper corner protectors on the paper separator to ensure that the paper separator can operate accurately. The bearing roller 2 is used to bear the paper corner protectors to ensure the stable transportation of a whole piece of pressed paper corner protectors. When the cutter 3 descends, the cutter 3 will gradually enter the cutting slit 210. At this time, the paper corner protectors on the bearing roller 2 will be cut by the cutter 3. Since the gap of the cutting slit 210 and the thickness of the cutter 3 are similar, the paper corner protectors will still be supported by the bearing roller 2 during cutting, thereby ensuring the flatness of the cutting surface and improving the quality of the product. The block 220 is set in the cutting slit 210 to close the cutting slit 210. When the cutting seam 210 is closed, after the cutter 3 falls, since the position of the protective block 310 is higher than that of the cutter 3, the protective block 310 will first contact the block 220 to prevent the cutter 3 from further falling. At this time, the paper corner protector will not be cut off. The protective block 310 can not only prevent the paper corner protector from being cut off, but also prevent the cutter 3 from directly contacting the block 220, thereby ensuring the sharpness of the blade of the cutter 3 and improving the quality of the product and the service life of the entire equipment. When cutting, by controlling whether there are blocks 220 at different positions to close the cutting seam 210, the paper corner protector can be cut into different lengths while the cutting speed remains unchanged, and precise control of the length can be achieved without other adjustments to the equipment.

[0038] Furthermore, the carrying roller 2 is shuttle-shaped and has a plane 201 and an inclined surface 202 . The inclined surface 202 is used to receive the paper corner protector, and the cutting seam 210 is located on the plane 201 and the inclined surface 202 .

[0039] In this embodiment, the supporting roller 2 is shuttle-shaped, and the position of the supporting roller 2 with the largest cross-sectional area is used to support the paper corner protector. The shuttle-shaped supporting roller 2 can just support the paper corner protector at ninety degrees, ensuring that the supporting roller 2 can fit perfectly with the paper corner protector during transportation and cutting, thereby ensuring the quality and efficiency of cutting.

[0040] In this embodiment, the stopper 220 is slidably set in the cutting seam 210. The user can choose whether to close the corresponding cutting seam 210 by sliding the stopper 220. When installing, the operator does not need to find or move the stopper 220 to other locations, thereby improving the speed and quality of the cutting operation.

[0041] Furthermore, the supporting roller 2 has a plurality of mounting grooves 230 , and also includes: a plurality of mounting blocks 221 slidably arranged on the stop block 220 , the stop block 220 slides into or leaves the mounting groove 230 , and after the mounting block 221 enters the mounting groove 230 , the mounting block 221 limits the stop block 220 from sliding in the cutting seam 210 .

[0042] In this embodiment, there are two mounting grooves 230, which are divided into upper and lower layers. When the mounting block 221 is located in the mounting groove 230 of the upper layer, the block 220 can completely close the cutting slit 210, and the cutter 3 cannot cut the paper corner protector here. When the mounting block 221 is installed in the mounting groove 230 of the lower layer, the block 220 will enter the cutting slit 210, and the cutting slit 210 will be exposed. The cutter 3 can enter the cutting slit 210 here for cutting. The double-layer mounting groove 230 design simplifies the installation process, makes the opening and closing of the cutting slit 210 simpler, and improves the efficiency of sorting. When the cutting slit 210 is cutting, paper scraps and the like will enter the cutting slit 210, and will accumulate in the cutting slit 210 after a long time. By changing the position of the block 220, the paper scraps or dust that originally entered the cutting slit 210 can be taken out under the movement of the block 220, preventing the blocking of the cutting slit 210 and improving the quality of production.

[0043] Furthermore, it also includes: a first rotating driving member 4 is arranged on the bracket 1, the first rotating driving member 4 has a first driving end 410, the first driving end 410 is connected to the bearing roller 2, and the first rotating driving member 4 is used to drive the bearing roller 2 to rotate.

[0044] In this embodiment, the first rotating drive member 4 is a motor, and may also be a motor or a hydraulic pump or other parts that can realize the rotation of the supporting roller 2 itself. The use of the motor can ensure that the rotation process and speed of the supporting roller 2 are smoother, and the rotation condition and speed of the supporting roller 2 can also be controlled, thereby improving the quality and efficiency of production.

[0045] Furthermore, it also includes: a first telescopic member 5 is arranged on the bracket 1, the first telescopic member 5 has a first telescopic end 510, the first telescopic end 510 is connected to the cutter 3, and the first telescopic member 5 is used to drive the cutter 3 to rise and fall.

[0046] In this embodiment, the first telescopic member 5 is a hydraulic cylinder, and may also be a pneumatic cylinder or other workpiece that performs the same function as a hydraulic cylinder. Through the design of the first telescopic member 5, the cutter 3 can be made to fall more stably and naturally, and can still stably cut even when encountering paper corner protectors of different thicknesses, thereby ensuring the cutting quality.

[0047] Furthermore, it also includes: a receiving bucket 6 is detachably arranged on the bracket 1, the receiving bucket 6 is located below the carrying roller 2, and the receiving bucket 6 is used to receive the dust and powder cut off by the cutter 3.

[0048] In this embodiment, powder and dust will be generated during cutting. Some of the dust will enter the cutting seam 210 and some will gradually fall down. The dust in the cutting seam 210 will also fall to the bottom of the bracket 1 when the supporting roller 2 rotates. The dust will eventually fall into the receiving bucket 6 to ensure the cleanliness of the bottom of the bracket 1, reducing the cleaning time.

[0049] Furthermore, it also includes: a limiting member 7 is arranged on the bracket 1, and a limiting space 710 is formed between the bracket 1 and the limiting member 7.

[0050] In this embodiment, the paper corner protector is located in the limiting space 710. The design of the limiting member 7 can ensure that the paper corner protector will not separate from the supporting roller 2 and the bracket 1 during the transportation process, ensure that the paper separator can operate stably, and ensure that no waste occurs.

[0051] Furthermore, it also includes: a collecting bucket 8 is arranged on the bracket 1, and the collecting bucket 8 is used to collect the paper corner protectors after cutting.

[0052] In this embodiment, the collection bucket 8 is used to collect the paper corner protectors after cutting is completed, which simplifies the collection process and does not require operators to sort them out bit by bit. The material discharging operation is only required after a certain batch of cutting is completed, which reduces the difficulty of production.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
