Description

Technical Field

[0001] This invention belongs to the field of printing technology, and in particular relates to a flatbed die-cutting and creasing machine for paper boxes. Background Technology

[0002] Printing is a technology that mass-produces original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials by transferring ink to the surface of materials such as paper, textiles, plastics, leather, PVC, and PC through processes such as plate making, inking, and pressing. Printing is the process of transferring approved printing plates onto the substrate using printing machinery and specialized inks.

[0003] Currently, the printing process involves multiple steps to cut and creasing the printed paperboard to facilitate subsequent production. Therefore, different types of machinery and equipment are often used to form a production line. However, most printing production lines are composed of multiple independent pieces of equipment, including die-cutting and creasing. Due to the poor overall connectivity of the equipment, this semi-automatic die-cutting and creasing method is not only complicated, labor-intensive, and inefficient, but also extremely dangerous. This outdated production process is no longer suitable for the needs of modern mechanized mass production.

[0004] Existing technologies, such as Chinese Patent Publication No. CN105799216A, disclose a flatbed paper box die-cutting and creasing machine. This solves the problem that current flatbed paper box printing production processes require step-by-step die-cutting and creasing operations, making it unsuitable for modern mechanized mass production. Specifically, it involves a flatbed paper box die-cutting and creasing machine, which is a key part of a paper box production line. The main equipment includes a pre-stamping section, an automatic paper feeding section, the die-cutting and creasing body, and the machine base. The paper receiving section and the electrical section set on the main body of the equipment are included. The automatic paper feeding section is connected to the output end of the pre-stamped paper section and is electrically driven. The output end of the automatic paper feeding section is connected to the creasing and die-cutting section. The die-cutting and creasing section is provided with an upper pressure plate and a lower pressure plate. The upper pressure plate is provided with a die-cutting knife for die-cutting and a creasing knife for creasing. The lower pressure plate is provided with a creasing strip. The creasing strip corresponds vertically to the creasing knife. The present invention has a simple structure and low cost. By adjusting the equipment group, the production speed and efficiency can be greatly improved.

[0005] However, during the die-cutting and creasing operations of the aforementioned flatbed carton die-cutting and creasing machine in the printing process, the die-cutting blade is constantly performing up and down die-cutting operations. Therefore, during the long-term die-cutting operation, the die-cutting blade itself generates heat due to friction, resulting in a high temperature. Furthermore, when the die-cutting blade cuts the corrugated paper, paper scraps are easily generated at the edges of the corrugated paper. These paper scraps may burn upon contact with the high temperature of the die-cutting blade, or the edges of the corrugated paper may become charred under the high temperature contact with the die-cutting blade, affecting the appearance of the product. Therefore, a flatbed carton die-cutting and creasing machine is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a flatbed die-cutting and creasing machine for paper boxes. By setting up a cleaning and contact mechanism, a transmission mechanism, and a reciprocating heat dissipation mechanism, it solves the problems of existing flatbed die-cutting and creasing machines, such as the high temperature of the die-cutting blade due to frictional heat during use, and the easy generation of paper scraps at the edges of the corrugated paper when the die-cutting blade is cutting the corrugated paper. These paper scraps may burn when they come into contact with the high temperature of the die-cutting blade.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0009] The cleaning mechanism includes a transmission rod movably mounted on the surface of the frame via a bearing, a swing plate connected to the surface of the transmission rod, and a cleaning plate.

[0011] A reciprocating heat dissipation mechanism, comprising a sleeve fixed to the frame near a fixed plate, a sliding rod horizontally sliding inside the sleeve, and a heat dissipation fan connected to one end of the sliding rod;

[0012] The top of the cooling fan is equipped with a transmission seat that is connected to the height adjustment mechanism via a torque component;

[0013] The transmission mechanism, connected to the height adjustment mechanism, is used to drive the cleaning and anti-collision mechanism and the reciprocating heat dissipation mechanism.

[0014] Furthermore, the cleaning contact mechanism also includes a contact mechanism, which includes an arc-shaped cover that is slidably sleeved on the top of the swing plate and a contact block fixed to one side of the fixed plate. The bottom of the contact block has a contact slope for forming a contact engagement with the top of the arc-shaped cover.

[0015] Furthermore, the transmission mechanism includes a first bevel gear fixed coaxially with the transmission rod, a second bevel gear meshing with one side of the first bevel gear, and a transmission gear fixed coaxially with the second bevel gear;

[0016] One side of the transmission gear is engaged with a toothed plate that slides with the frame, and the transmission rod is located at the bottom of the first bevel gear and is also equipped with an intermittent transmission mechanism.

[0017] Furthermore, the intermittent transmission mechanism includes a drive gear fixed to the bottom of the transmission rod and an incomplete gear meshing with one side of the drive gear, wherein the incomplete gear is fixedly engaged with the sleeve.

[0018] Furthermore, the transmission mechanism also includes a protective side plate, which is located on one side of the transmission gear and sleeved on the surface of the transmission gear.

[0019] Furthermore, the height adjustment mechanism includes an electric push rod fixed to the top of the frame, a suspension frame fixed to the output end of the electric push rod, and an auxiliary rod slidably disposed on both sides of the surface of the suspension frame and fixedly engaged with the frame. The die-cutting knife and the creasing knife are respectively fixed on both sides of the lower surface of the suspension frame. The height adjustment mechanism also includes a connecting frame fixed to the outside of the suspension frame. The transmission seat and the toothed plate are both fixedly engaged with the connecting frame.

[0020] Furthermore, the cleaning plate includes a first plate and a second plate, the first plate and the second plate are symmetrically arranged about the bottom of the swing plate, and the bottom of the first plate and the second plate form a height gap with the frame under the elastic force of the resisting spring.

[0021] Both the first plate and the second plate have curved chamfers on their outer sides.

[0022] Furthermore, the torque component includes a housing fixedly disposed at the bottom of the transmission seat and arc-shaped springs symmetrically disposed on both sides of the housing. The free ends of the arc-shaped springs are jointly fixedly provided with connecting columns, and one end of the connecting column is slidably engaged with the housing, while the other end is fixedly engaged with the top of the cooling fan.

[0023] Furthermore, a guide plate is provided on the other side of the frame, and the guide plate is set at a 45-degree angle to the outer side of the frame.

[0024] Furthermore, both sides of the upper surface of the frame are located near the transmission mechanism and are housed in the protective housing, and the surface of the transmission gear is provided with an L-shaped support frame that penetrates the protective housing and is fixedly engaged with the frame.

[0025] The present invention has the following beneficial effects:

[0026] 1. Through the set cleaning and contact mechanism, during the downward pressing operation of the die-cutting knife and creasing knife driven by the height adjustment mechanism, the connecting frame synchronously drives the swing plate to swing through the transmission mechanism. During the swinging process on the surface of the flat cardboard box, the debris on the flat cardboard box can be pre-cleaned, reducing the possibility of spontaneous combustion of debris due to the high temperature of the die-cutting knife. At the same time, when the die-cutting knife is performing the die-cutting operation, the swing plate swings to the other side of the die-cutting groove without affecting the die-cutting operation. Meanwhile, after the die-cutting knife has pre-cleaned the die-cutting position of the flat cardboard box during the swinging process, the arc-shaped cover on the swing plate will abut against the surface of the contact block. Through the abutting action of the contact block, the contact mechanism is pressed against the surface of the flat cardboard box, so that the flat cardboard box can remain more stable during the creasing process, and it is not easy to deviate, which is conducive to more precise die-cutting and creasing operations.

[0027] 2. Through the set cleaning and intermittent transmission mechanism, during the downward pressing operation of the die-cutting blade and creasing blade driven by the height adjustment mechanism, the intermittent transmission mechanism can drive the cooling fan to swing back and forth. The cooling fan can blow air to cool the surface of the die-cutting blade. In addition, through the cooperation of the transmission seat, the heat dissipation fan can move synchronously with the die-cutting blade, thereby achieving a better heat dissipation effect. This greatly reduces the possibility of the die-cutting blade scorching at the edge of the flat cardboard box due to its own high temperature, which is beneficial to the aesthetics of the printed products.

[0028] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0050] Example 1

[0051] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the present invention is a flatbed carton die-cutting and creasing machine, including a frame 10, a height adjustment mechanism 20 installed on the top of the frame 10, a die-cutting blade 101 and a creasing blade 102 respectively disposed on both sides of the lower surface of the height adjustment mechanism 20, a conveyor 103 connected to one side of the frame 10, a die-cutting groove 104 and a creasing block 105 respectively opened on both sides of the upper surface of the frame 10 and corresponding to the die-cutting blade 101 and the creasing blade 102, and fixed plates 106 symmetrically disposed on both sides of the upper surface of the frame 10. It also includes a cleaning and contact mechanism 30, a reciprocating heat dissipation mechanism 50 and a cleaning and contact mechanism 30.

[0052] A guide plate 107 is provided on the other side of the frame 10, and the guide plate 107 is set at a 45-degree angle to the outer side of the frame 10.

[0053] The height adjustment mechanism 20 includes an electric push rod 201 fixed to the top of the frame 10, a suspension frame 202 fixed to the output end of the electric push rod 201, and an auxiliary rod 203 slidably disposed on both sides of the surface of the suspension frame 202 and fixedly engaged with the frame 10. The die-cutting knife 101 and the creasing knife 102 are respectively fixed on both sides of the lower surface of the suspension frame 202. The height adjustment mechanism 20 also includes a connecting frame 204 fixed to the outside of the suspension frame 202.

[0054] Specifically, during the conveying process of the flattened paper box after printing on the output machine 103, the flattened paper box can be moved horizontally to the surface of the frame 10. When it moves to the designated position, the electric push rod 201 is activated to drive the suspension frame 202 and the die-cutting knife 101 and creasing knife 102 on it to move downward synchronously. During the movement, through the cooperation of the transmission mechanism 40, the cleaning and contacting mechanism 30 swings to clean the surface of the flattened paper box, thereby cleaning the debris on it and reducing the possibility of spontaneous combustion of the die-cutting knife due to high temperature and debris.

[0055] At the same time, the transmission mechanism 40 can drive the reciprocating heat dissipation mechanism 50 to swing intermittently, so that both sides of the die-cutting blade 101 can be blown to dissipate heat, which greatly reduces the possibility of the die-cutting blade burning on the edge of the flat cardboard box due to its own high temperature, and is beneficial to the aesthetics of the printed products.

[0056] Example 2

[0057] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown,

[0058] The cleaning mechanism 30 includes a transmission rod 301 movably mounted on the surface of the frame 10 via a bearing, a swing plate 302 connected to the surface of the transmission rod 301, and a cleaning plate 303.

[0059] Among them, the swing plate 302 slides through the fixed plate 106 and is slidably engaged with the cleaning plate 303, and the surface of the cleaning plate 303 is fitted with an anti-spring 304 that is fixedly engaged with the bottom of the swing plate 302.

[0060] Specifically, when the cleaning and resisting mechanism 30 is driven by the transmission mechanism 40, the swing plate 302 can swing inside the fixed plate 106, so that the cleaning plate 303 on it can clean the debris on the flat cardboard box. Before die cutting, one end of the cleaning plate 303 is on the other side of the die cutting groove 104, so as not to obstruct the die cutting operation of the die cutting knife 101.

[0061] As a further optimization of this embodiment: the cleaning contact mechanism 30 also includes a contact mechanism 310. The contact mechanism 310 includes an arc-shaped cover 311 slidably sleeved on the top of the swing plate 302 and a contact block 312 fixed on one side of the fixed plate 106. The bottom of the contact block 312 is formed with a contact slope 313 for forming a contact engagement with the top of the arc-shaped cover 311. When the swing plate 302 and the cleaning plate 303 swing and clean, the arc-shaped cover 311 will gradually contact the contact slope 313 and eventually form a contact state. After the arc-shaped cover 311 is contacted, it will slide on the surface of the swing plate 302 to contact the surface of the cleaning plate 303 and then contact the surface of the flat-pressed paper box. Thus, when the flat-pressed paper box is about to be die-cut and creasing, it forms a contact fixation on the flat-pressed paper box, making it less likely to move on its own, thereby ensuring the accuracy of die-cutting and creasing.

[0062] As a further optimization of this embodiment: the cleaning plate 303 includes a first plate 3031 and a second plate 3032. The first plate 3031 and the second plate 3032 are symmetrically arranged about the bottom of the swing plate 302. The bottom of the first plate 3031 and the second plate 3032 forms a height gap with the frame 10 under the elastic force of the anti-spring 304. This height gap facilitates the insertion of the flat-pressed paper box. The outer sides of the first plate 3031 and the second plate 3032 are both formed with arc chamfers 3033. During the swing cleaning process of the swing plate 302, the first plate 3031 and the second plate 3032 will swing synchronously. During the swing, the bottom of the plate can contact the surface of the flat-pressed paper box through the elastic force of the anti-spring 304, thereby achieving better cleaning of the debris on it.

[0063] Example 3

[0064] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown,

[0065] The reciprocating heat dissipation mechanism 50 includes a sleeve 501 fixed to the frame 10 near the fixed plate 106, a sliding rod 502 that slides horizontally up and down inside the sleeve 501, and a cooling fan 503 connected to one end of the sliding rod 502.

[0066] Among them, the top of the cooling fan 503 is provided with a transmission seat 504 that is in transmission cooperation with the height adjustment mechanism 20 via a torque component;

[0067] The torque component includes a housing 505 fixedly disposed at the bottom of the transmission seat 504 and an arc spring 506 symmetrically disposed on both sides of the housing 505. The free ends of the arc springs 506 are jointly fixedly provided with a connecting post 507, and one end of the connecting post 507 is slidably engaged with the housing 505, and the other end is fixedly engaged with the top of the cooling fan 503.

[0068] Specifically, when the height adjustment mechanism 20 drives the die-cutting blade 101 and the creasing blade 102 to perform a downward pressing operation, the transmission mechanism 40 can drive the reciprocating heat dissipation mechanism 50 to rotate reciprocally, thereby blowing air to dissipate heat on both sides of the die-cutting blade 101, which greatly reduces the possibility of the die-cutting blade easily scorching at the edge of the flat cardboard box due to its own high temperature, and is beneficial to the aesthetics of the printed products.

[0069] Example 4

[0070] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown,

[0071] The transmission mechanism 40 is connected to the height adjustment mechanism 20 to drive the cleaning and anti-collision mechanism 30 and the reciprocating heat dissipation mechanism 50.

[0072] The transmission mechanism 40 includes a first bevel gear 401 fixed coaxially with the transmission rod 301, a second bevel gear 402 meshing with one side of the first bevel gear 401, and a transmission gear 403 fixed coaxially with the second bevel gear 402.

[0073] One side of the transmission gear 403 is meshed with a toothed plate 404 that slides with the frame 10, and the transmission rod 301 is located at the bottom of the first bevel gear 401 and is also provided with an intermittent transmission mechanism 410.

[0074] The upper surface of the frame 10 is provided with protective housings 108 on both sides near the transmission mechanism 40, and the surface of the transmission gear 403 is provided with an L-shaped support frame that passes through the protective housing 108 and is fixedly engaged with the frame 10. The transmission seat 504 and the tooth plate 404 are fixedly engaged with the connecting frame 204. The surface of the protective housing 108 is provided with a through groove to facilitate the movement of the tooth plate 404.

[0075] Specifically, in Embodiment 2, when the cleaning resistance mechanism 30 is driven to perform swing cleaning, the output end of the electric push rod 201 drives the suspension frame 202 to move down, causing the connecting frame 204 on it to drive the toothed plate 404 connected to it to move down, so that the toothed plate 404 and the meshing transmission gear 403 form a meshing transmission, and the transmission gear 403 drives the second bevel gear 402 on it to rotate, so that the second bevel gear 402 and the first bevel gear 401 form a meshing rotation, and the first bevel gear 401 drives the transmission rod 301 to rotate;

[0076] During rotation, the transmission rod 301 synchronously drives the swing plate 302 to swing and clean. When the electric push rod 201 moves down to a suitable height and is about to contact the surface of the flat cardboard box for die-cutting and creasing, the swing plate 302 has already swung to the other side of the die-cutting groove 104. During its swing, it does not obstruct the movement of the die-cutting knife and creasing knife. Furthermore, through the setting of the abutting inclined surface 313, the cleaning plate 303 forms abutment and fixation against the flat cardboard box, which facilitates more stable die-cutting and creasing operations. After die-cutting and creasing, the electric push rod 201 resets, and synchronously, through the cooperation of the transmission mechanism 40, the cleaning abutment mechanism 30 on it returns to its original position. Figure 1 The position status shown;

[0077] As a further optimization of this embodiment: the intermittent transmission mechanism 410 includes a drive gear 411 fixed to the bottom of the transmission rod 301 and an incomplete gear 412 meshing with one side of the drive gear 411. The incomplete gear 412 is fixedly engaged with the sleeve 501. During the die-cutting and creasing operation when the electric push rod 201 is pressed down, the rotating transmission rod 301 drives the drive gear 411 to rotate, causing the incomplete gear 412 meshing with it to rotate. When the incomplete gear 412 rotates, it drives the sliding rod 502 to rotate through the sleeve 501, causing the sliding rod 502 to drive the diffuser... The heat fan 503 rotates, and during the rotation of the heat fan 503, it drives the connecting column 507 on it to rotate, causing the arc spring 506 inside the housing 505 to be compressed. When the incomplete gear 412 does not mesh with the driving gear 411, the elastic force of the arc spring 506 can make the connecting column 507 rotate again, driving the heat fan 503 and the sleeve 501 on it to rotate and reset, so that the driving gear 411 can mesh with the incomplete gear 412 again during the rotation. This process is repeated to achieve heat dissipation for the die-cutting blade 101, and also to achieve a more comprehensive heat dissipation operation.

[0078] At the same time, the movable connecting frame 204 can synchronously drive the transmission seat 504 to rise and fall in height, so that the cooling fan 503 on it can move synchronously with the movement of the die-cutting blade 101, thereby improving the heat dissipation effect of the die-cutting blade 101 and greatly reducing the possibility of the die-cutting blade 101 easily scorching the edge of the flat cardboard box due to its own high temperature, which is beneficial to the aesthetics of the printed products.

[0079] As a further optimization of this embodiment, the transmission mechanism 40 also includes a protective side plate 405. The protective side plate 405 is located on one side of the transmission gear 403 and is sleeved on the surface of the transmission gear 403. By setting the protective side plate 405, protection can be formed on one side of the transmission gear 403, which is conducive to better meshing and transmission of the transmission gear 403.
