Description

Technical Field

[0001] The invention relates to the technical field of paper box cutting equipment, and in particular to a paper scrap removing blade and a paper box cutting mechanism thereof. Background Art

[0002] In traditional paper cutters, when the upper circular knife cuts with the lower circular knife, the circular knife mechanism will vibrate to a certain extent. Especially when the cutting speed reaches a certain level, the entire knife holder and the two circular knives begin to vibrate, and part of the paper will have "threads", or seem to be broken, or "burrs". And when the mechanical wallboard resonates, the paper cutter cannot complete the paper cutting operation, and in serious cases, the cutter will be damaged.

[0003] At present, the paper box cutting mechanism is not perfect and cannot meet the requirements of manufacturers. It has the following disadvantages: 1. When the circular knife mechanism cuts the paper box, it is easy to have burrs and other undesirable phenomena; 2. Excess paper scraps are easily generated between the two circular paper cutting knives. The paper scraps cannot be discharged in time and will interfere with the operation of the machine.

[0004] In view of the shortcomings of the above-mentioned conventional paper box cutting mechanism, the applicant adheres to the spirit of research innovation and excellence, combines production practice, and uses professional and scientific methods to propose a practical solution, and therefore files this application. Summary of the invention

[0005] The purpose of the present invention is to provide a paper scrap removing blade and a paper box cutting mechanism thereof in view of the existing technical status, which can lift up the paper surface to be cut by picking up the paper piece, and then quickly cut it by the upper blade and the lower blade.

[0006] A paper scrap removing blade comprises: an upper blade and a lower blade, a paper picking piece, a rotating shaft, and a blade fixing seat, wherein the upper blade and the lower blade are mounted on the rotating shaft and the rotating shaft drives the upper blade and the lower blade to rotate, the rotating shaft is mounted on the blade fixing seat and connected to a driving device, the paper picking piece located between the upper blade and the lower blade is mounted on the blade fixing seat, and the paper picking angle of the paper picking piece extends to the contact surface between the upper blade and the lower blade and the cutting object.

[0007] Specifically, a paper scrap baffle is provided between the upper blade and the lower blade, and a passage for discharging paper scraps is formed between the paper scrap baffle and the paper picking member. Paper scraps generated after cutting can be discharged through the passage to prevent paper scraps from getting stuck inside the mechanical equipment.

[0008] Specifically, one end of the paper scrap baffle is fixed on the blade fixing seat, and the rotating shaft passes through the other end of the paper scrap baffle. The side of the paper scrap baffle close to the paper picking piece is provided with an outer arc chamfer, and the side of the paper picking piece close to the paper scrap baffle is an inner arc chamfer. The outer arc chamfer and the inner arc chamfer cooperate with each other to form a channel with an arc guide rail, and cooperate with the rotation direction of the circular upper and lower blades to throw the paper scraps out of the channel.

[0009] Specifically, the upper blade and the lower blade are symmetrically installed on the rotating shaft, and both the upper blade and the lower blade are circular blades. The blade of the upper blade is set at the edge of the upper surface, and the blade of the lower blade is set at the edge of the lower surface. The inner sides of the upper blade and the lower blade are flat, and the paper scrap baffle is clamped between the two planes of the upper blade and the lower blade. The paper scrap baffle plays a role in guiding paper scraps, thereby quickly discharging paper scraps and preventing paper scraps from interfering with the rotation of the upper blade and the lower blade and the operation of the equipment.

[0010] Specifically, the top of the paper lifting corner extends from one side to the other side of the cutting point between the upper blade and the lower blade and the cutting object, and the paper lifting corner preferentially contacts the cutting point of the cutting object and props up the cutting surface of the cutting object, and then the upper blade and the lower blade cut the cutting surface.

[0011] Specifically, the blade fixing seat described in the paper box cutting mechanism is installed on one side of the conveyor belt, and limit rails are provided on the left and right sides of the conveyor belt. The limit rail located on one side of the blade fixing seat is provided with a width adjustment strip. The upper blade and the lower blade both pass through the gap between the width adjustment strips, and the paper picking piece passes through the gap. The driving device drives the upper blade and the lower blade to rotate through the rotating shaft.

[0012] Specifically, the rotation direction of the upper blade and the lower blade is the same as the direction in which the conveyor belt transports the paper box, the paper picking angle of the paper picking member is opposite to the direction in which the conveyor belt transports the paper box, and the paper picking member and the paper scrap baffle are located in a horizontal plane.

[0013] Specifically, the channel formed between the paper scrap baffle and the paper picker is on the same parallel horizontal plane as the gap, the gap is located at the same height as the cutting line of the paper box, and the upper blade, the lower blade and the paper picker are perpendicular to the cutting surface of the paper box.

[0014] Specifically, the width adjustment strip is arranged on one side of the blade fixing seat, and two adjustment blocks are arranged on the other side of the blade fixing seat. The width adjustment strip is placed on one side of the blade fixing seat, and two adjustment blocks are arranged on the inner side of the width adjustment strip on the blade fixing seat.

[0015] The beneficial effects of the present invention are:

[0016] 1. This device first props up the outer wrapping paper of the paper box through the paper picking corner of the paper picking part, and then the upper blade and the lower blade rotate at high speed to cut the outer wrapping paper of the paper box. This design uses the paper picking corner to prop up the outer wrapping paper first, playing an important supporting and guiding role, ensuring that the upper blade and the lower blade can accurately contact and cut the outer wrapping paper, and ensuring the neatness of the cutting line of the outer wrapping paper.

[0017] 2. The paper picking part and the paper scrap baffle form a channel to ensure the continuous high-speed operation of the device and timely discharge the paper scraps. Moreover, the paper picking part and the paper scrap baffle are arranged between the upper and lower blades, maintaining sufficient stability during the high-speed rotation process, avoiding excessive turbulence between the upper and lower blades, resulting in an uneven cutting line.

[0018] 3. Traditional mechanical designs require short pauses to discharge paper scraps to prevent them from getting stuck in the mechanical equipment. Therefore, the transportation speed of the paper box is a variable, resulting in unstable cutting of the paper box by the circular knife. The cutting paper box mechanism of the present invention, in cooperation with the paper scrap removing blade, can operate continuously at high speed and stably, and its accuracy has also increased significantly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The drawings are only for illustrative purposes and should not be construed as limitations on this patent; for better illustration of this embodiment, some components in the drawings may be omitted, enlarged or reduced, and do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The positional relationships described in the drawings are only for illustrative purposes and should not be construed as limitations on this patent.

[0025] There are many types of cigarette cases on the market, and their structures are becoming increasingly complex. Therefore, the manufacturing equipment for cigarette cases also needs to be improved according to requirements. An anti-paper debris blade and its cigarette case cutting mechanism are developed for the cutting step of a specific outer packaging paper of a cigarette case. The above cigarette case has an inner and an outer layer, and the two layers have an opening function. After the outer packaging paper is covered on the outer surface of the cigarette case, the outer packaging paper needs to be cut at a specified position to facilitate the opening of the two-layer cigarette case. One end of the position to be cut is connected to the side packaging paper, while the other end is open and not connected to the side packaging paper.

[0026] Please refer to Figures 1 to 4 shown in the structural schematic diagram of the present invention. An anti-paper debris blade includes: an upper blade, a lower blade, a paper picking member, a rotating shaft, and a blade fixing seat. The upper blade and the lower blade are installed on the rotating shaft, and the rotating shaft drives the upper blade and the lower blade to rotate. The rotating shaft is installed on the blade fixing seat and connected to a driving device. The paper picking member located between the upper blade and the lower blade is installed on the blade fixing seat, and the paper picking angle of the paper picking member extends to the contact surface between the upper blade and the lower blade and the object to be cut. The paper picking angle preferentially enters the cutting surface through the gap on the open side of the cigarette case, and then the outer packaging paper is cut by the upper blade and the lower blade.

[0027] In the above solution, a paper debris baffle is provided between the upper blade and the lower blade. A channel for discharging paper debris is formed between the paper debris baffle and the paper picking member. One end of the paper debris baffle is fixed on the blade fixing seat, and the rotating shaft penetrates the other end of the paper debris baffle. An outer arc chamfer is provided on the side of the paper debris baffle close to the paper picking member, and an inner arc chamfer is provided on the side of the paper picking member close to the paper debris baffle. The outer arc chamfer and the inner arc chamfer cooperate with each other to form a channel with an arc guide rail. The arc guide rail facilitates the paper debris to be thrown out of the channel. The front section of the channel is an arc guide rail, while the rear section of the channel is a straight guide rail. The outside of the paper picking member abuts against the side plate of the blade fixing seat and is fixed on the blade fixing seat by bolts. Since the paper picking member is thin and needs to pick up the outer packaging paper while the cigarette case moves forward, the paper picking member needs a certain supporting force to avoid bad phenomena such as tool withdrawal, jumping, and bending of the paper picking member, and to extend the service life of the paper picking member.

[0028] In the above solution, the upper blade and the lower blade are symmetrically installed on the rotating shaft. Both the upper blade and the lower blade are circular blades. The cutting edge of the upper blade is provided at the edge of the upper surface, and the cutting edge of the lower blade is provided at the edge of the lower surface. The inner sides of the upper blade and the lower blade are flat surfaces. The paper debris baffle is clamped between the two flat surfaces of the upper blade and the lower blade. The paper picking member and the paper debris baffle are kept in the same horizontal plane, and the upper and lower blades can remain stable during high-speed operation, so as to ensure the neatness of the cutting line.

[0029] In the above solution, the top end of the paper picking corner extends from one side to the other side of the cutting point of the upper blade and the lower blade with the cutting object. The paper picking corner is aligned with the gap at the bottom of the inner and outer layers of the cigarette case, and the outer wrapping paper is lifted up, and then cut by the upper and lower blades. The inner and outer layers of the cigarette case also play a certain role in guiding the paper picking part to prevent the paper picking part from bending and breaking.

[0030] A cutting carton mechanism with a paper scrap removing blade. The blade fixing seat is installed on one side of the conveyor belt. Limit rails are provided on both the left and right sides of the conveyor belt. A width adjusting strip is provided on the limit rail on one side of the blade fixing seat. The upper blade and the lower blade both pass through the gap between the width adjusting strips, and the paper picking part passes through the gap. The driving device drives the upper blade and the lower blade to rotate through a rotating shaft. The conveyor belt is driven by a motor, a rotating shaft and a gear set. The cigarette case is sequentially conveyed to each process through the conveyor belt. The driving device generally uses a motor, and another motor is used to separately control the rotation of the rotating shaft, and the rotating shaft drives the upper and lower blades to rotate at high speed.

[0031] In the above solution, the rotating directions of the upper blade and the lower blade are the same as the direction of the conveyor belt transporting the carton. The paper picking corner of the paper picking part is opposite to the direction of the conveyor belt transporting the carton. The paper picking part and the paper scrap baffle are in a horizontal plane. The channel formed between the paper scrap baffle and the paper picking part is in the same parallel horizontal plane as the gap. The gap is at the same height as the cutting line of the carton. The upper blade, the lower blade and the paper picking part are perpendicular to the cutting surface of the carton. The extending direction of the paper picking corner is opposite to the transporting direction of the carton, so that the paper picking corner can smoothly enter from the open side of the carton. The upper blade and the lower blade cut the outer wrapping paper by rotating at high speed, and the rotational speed of the blade is related to the moving speed of the cigarette case and can be increased proportionally at the same time, thereby improving the production efficiency of the equipment.

[0032] In the above solution, the width adjusting strip is arranged on one side of the blade fixing seat. Two adjusting blocks are installed on the other side of the blade fixing seat. The width adjusting strip abuts against one side of the blade fixing seat, and the inner position of the width adjusting strip is where the two adjusting blocks are installed on the blade fixing seat. The adjusting bolts pass through the adjusting blocks and respectively abut against the width adjusting strip and the blade fixing seat. By rotating the adjusting bolts, the width adjusting strip and the blade fixing seat are pushed out, so as to adjust the distance between the width adjusting strip and the blade fixing seat and the limit rail on the other side, which can be applicable to cigarette cases of any size.

[0033] The conveyor belt of the carton cutting mechanism transports a number of cigarette cartons in one direction, and they move forward neatly within the limit rails on both sides. The open side of the bottom of the cigarette carton moves to the paper picking part, and the paper picking corner of the paper picking part preferentially inserts into the gap between the bottom of the cigarette carton and the outer wrapping paper. Since the paper picking corner slightly lifts the outer wrapping paper. At this time, the upper blade and the lower blade come into contact with the outer wrapping paper on both sides of the paper picking corner. The conveyor belt continues to drive the cigarette carton to move forward. While the upper blade and the lower blade are cutting, a piece of paper is also cut out from the outer wrapping paper. Since both the upper blade and the lower blade keep rotating at high speed, this inertia is used to make a piece of paper enter the linear guide from the arc guide rail section of the channel, so as to quickly discharge the paper and avoid the paper interfering with the rotation of the upper blade and the lower blade and the operation of the equipment.

[0034] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
