Description

Technical Field

[0001] The present invention relates to the technical field of embossing machines, and particularly to an adjusting mechanism for an embossing roller of an embossing machine. Background Art

[0002] As an important packaging surface treatment device, an embossing machine plays a key role in the production and processing of various packaging products such as cosmetic boxes, gift boxes, medicine boxes, cigarette boxes, wine boxes, tea boxes, and handbags. Its main function is to emboss the surfaces of these packaging products. By forming specific textures and patterns on the material surface, it can not only enhance the beauty and texture of the products, but also play a certain role in anti-counterfeiting and brand identification.

[0003] During the actual working process of the embossing machine, pressure is a crucial parameter, which directly determines the embossing effect and quality. Appropriate pressure can make the embossing pattern clear, uniform, and with a moderate depth, thus meeting the design requirements of different products. However, if the pressure is too large or too small, it may cause the embossing pattern to be blurred, deformed, or even damage the material, seriously affecting the appearance and quality of the products.

[0004] However, the existing embossing machines currently have certain limitations in pressure adjustment. Usually, the method adopted is to manually turn a threaded rod to adjust the gap size between two embossing rollers, thereby achieving pressure adjustment. Although this manual operation method is simple and direct, it has obvious drawbacks. Due to relying entirely on manual operation, it is very difficult to precisely control the parallelism of the two rollers. During the adjustment process, operators may, due to factors such as lack of experience, uneven operation force, or visual errors, cause the two rollers to fail to maintain an ideal parallel state. Once the parallelism of the rollers deviates, the pressure distribution on the material passing through the rollers will be uneven, thereby causing problems such as inconsistent embossing depth or unstable pressure. This will not only affect the appearance quality of the products, reduce the qualified rate of the products, but also may increase production costs and reduce production efficiency. Summary of the Invention

[0005] The object of the present invention is to solve the problem that the existing embossing machine has certain limitations in pressure adjustment. Usually, the method adopted is to manually turn the threaded rod to adjust the gap between the two embossing rollers, thereby achieving pressure adjustment. Although this manual operation method is simple and direct, it has obvious drawbacks. Since it completely relies on manual operation, it is very difficult to precisely control the parallelism of the two rollers. During the adjustment process, due to factors such as insufficient experience, uneven operation force, or visual error of the operator, the two rollers may not be able to maintain an ideal parallel state. Once the parallelism of the rollers deviates, the pressure distribution received by the material when passing through the rollers will be uneven, resulting in inconsistent embossing depth or unstable pressure. This will not only affect the appearance quality of the product, reduce the qualification rate of the product, but also may increase production costs and reduce production efficiency. Therefore, the proposed solution is put forward.

[0006] To achieve the above object, the present invention adopts the following technical solution: an adjustment mechanism for the embossing rollers of an embossing machine, which includes a frame body. The frame body includes a bottom plate and two support frames. A support column is connected between the two support frames. It also includes a rotation component and an adjustment component assembled on one side of the support frame. A detection component is installed on one side of the support frame. The detection component includes an inclined pressure rod fixedly installed at the bottom of the lower embossing roller in the adjustment component, and an extension rod fixedly connected to one side of the support frame. One side of the extension rod is fixedly connected with a mounting block. A chute is opened inside the mounting block. A slider is slidably connected to the inner wall of the mounting block. And one side of the slider is connected with a contact block that abuts against the inclined pressure rod. The slider and the chute are connected by an elastic member. A scale line is arranged on one side of the mounting block. The top of the slider is connected with a pointer. As the lower embossing roller descends, the inclined pressure rod presses against the contact block, causing the contact block to push the slider to slide, and at the same time driving the pointer to slide and point to the scale line.

[0007] As a further description of the above technical solution: The elastic member includes a positioning rod fixedly connected to the inner wall of the chute. One side of the slider is fixedly connected with a moving plate that slidably connects with the positioning rod. A telescopic spring is sleeved on the outer periphery of the positioning rod.

[0008] As a further description of the above technical solution: A pushing component is installed on one side of the slider. The pushing component includes a fixed frame fixedly connected to one side of the slider. An installation rod is fixedly connected to the inner wall of the fixed frame. The installation rod is rotatably connected with a rotating plate through a torsion spring sleeved on its outer periphery. An avoidance groove is opened on the side of the mounting block. A telescopic member that contacts the rotating plate is fixedly connected to the side of the mounting block.

[0009] As a further description of the above technical solution: The telescopic member includes an L-shaped plate fixedly connected to the bottom of the mounting block. A plurality of push rods are slidably connected to the inner wall of the L-shaped plate, and an arc-shaped plate is fixedly connected to one side of the plurality of push rods. A pressure spring is sleeved on the outer circumference of two of the push rods, and each push rod is connected to the contact plate through an extrusion member inside.

[0010] As a further description of the above technical solution: The elastic force of the torsion spring is greater than the elastic forces of the two pressure springs.

[0011] As a further description of the above technical solution: The extrusion member includes a groove opened inside the push rod. A moving rod connected to the contact plate is slidably connected to the inner wall of the groove. An extrusion spring is connected between the moving rod and the groove. A slot is penetrated through the outer circumference of the groove. A measuring rod extending out of the slot is fixedly connected to the outer circumference of the moving rod, and the measuring rod is slidably connected with the slot.

[0012] As a further description of the above technical solution: The rotating assembly includes a connecting cylinder fixedly connected to one side of the support frame. An installation frame is fixedly installed on the side of the connecting cylinder. A servo motor is installed on the side of the installation frame, and the servo motor is fixedly connected to a pulley through an output shaft. A rotating shaft is rotatably connected to the inner wall of the support frame, and a pulley is also fixedly connected to the outer circumference of the rotating shaft. The two pulleys are connected by a belt, and a patterned roller is fixedly connected to the outer circumference of the rotating shaft.

[0013] As a further description of the above technical solution: The adjusting assembly includes two hydraulic cylinders installed on the side of the support frame. The output end of the hydraulic cylinder passes through the support frame and is connected to a hydraulic rod. The hydraulic rod is connected to a pressing roller through a connecting sleeve at the bottom.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: By providing the adjusting assembly, the detecting assembly and the pushing assembly, in order to flexibly adjust the pressure between the patterned roller and the pressing roller, the hydraulic cylinder can be used to drive the hydraulic rod to move up and down. When the hydraulic rod rises, it drives the connecting sleeve and the pressing roller to rise synchronously, increasing the distance between the two, thereby reducing the pressure. On the contrary, when the hydraulic rod descends, it drives the pressing roller to descend, reducing the distance and increasing the pressure; At the same time, when the pressing roller descends, it will drive the inclined pressing rod to descend, push the abutting block, and push the slider to slide in the mounting block. When the slider moves, on the one hand, it drives the moving plate to slide on the outer circumference of the positioning rod and compresses the telescopic spring, and on the other hand, it drives the pointer to move so that it points to the scale line. The operator can judge whether the pressing roller is horizontal by observing whether the left and right pointers are on the same scale line. If it is found that the pressing roller is not horizontal, the corresponding hydraulic rod can be driven to rise and fall by starting different hydraulic cylinders to adjust the levelness of the pressing roller; After long-term embossing operation, the embossing roller may be deformed. At this time, the servo motor can be started to drive the embossing roller to rotate first, and then the hydraulic cylinder is started to drive the hydraulic rod to descend, so that the lower pressing roller descends. The descent of the lower pressing roller drives the inclined pressing rod to descend, presses against the abutting block, and pushes the slider to slide in the mounting block. The movement of the slider drives the fixed frame to move, and the fixed frame pushes the rotating plate to move through the mounting rod. At this time, the torsion spring is in a compressed state. When the limiting plate on one side of the abutting block contacts the mounting block, the slider cannot continue to slide, and the rotating plate just moves to one side of the avoidance groove and is no longer restricted by the mounting block. The torsion spring in the compressed state begins to rebound, driving the rotating plate to rotate 90 degrees. When the rotating plate rotates, it presses against the arc-shaped plate to move, and the arc-shaped plate drives a number of push rods to move in the L-shaped plate, and at the same time compresses the pressure spring. During the movement of the push rod, under the elastic force of the compression spring, the moving rod is driven to move, so that the moving rod drives the contact plate to move towards the embossing roller until it is attached to the embossing roller. If the rotating embossing roller is not deformed, a number of contact plates will not move. If the embossing roller is deformed, the deformed part will push the contact plate, causing the contact plate to drive the moving rod to move in the groove and press against the compression spring. At the same time, the moving rod will drive the measuring rod to move in the slot, and the operator can judge the degree of deformation and damage of the embossing roller by observing the movement of the measuring rod.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0018] As Figures 1 - 10 shown, an adjusting mechanism for a pressure roller of a embossing machine provided by the present invention includes a frame body 10. The frame body 10 includes a bottom plate 11 and two support frames 12. The two support frames 12 are fixedly connected to the top of the bottom plate 11. A support column 13 is connected between the two support frames 12. It further includes a rotating assembly 20 and an adjusting assembly 30 assembled on one side of the support frame 12.

[0019] As Figure 1 、 Figure 2 shown, the rotating assembly 20 includes a connecting cylinder 21 fixedly connected to one side of the support frame 12. A mounting bracket 22 is fixedly installed on the side surface of the connecting cylinder 21. A servo motor 23 is installed on the side surface of the mounting bracket 22. And the servo motor 23 is fixedly connected to a pulley 25 through an output shaft. The inner wall of the support frame 12 is rotatably connected to a rotating shaft 24. A pulley 25 is also fixedly connected to the outer periphery of the rotating shaft 24. The two pulleys 25 are connected by a belt 26. A pattern roller 27 is fixedly connected to the outer periphery of the rotating shaft 24; When performing embossing operations on the paper box, it is necessary to first start the servo motor 23. After the servo motor 23 starts, its output shaft begins to rotate, thereby driving the pulley 25 installed on the outer periphery of the output shaft to rotate together. As the pulley 25 rotates, the belt 26 connected to it moves accordingly. Under the driving action of the belt 26, the pulley 25 on the outer periphery of the rotating shaft 24 also starts to rotate. Driven by the pulley 25, the rotating shaft 24 rotates synchronously and further drives the embossing roller 27 connected to it to rotate. At this time, the embossing roller 27 cooperates with the lower pressing roller 34 in the adjusting assembly 30 to apply pressure to the paper box, thus completing the embossing operation of the paper box.

[0020] As Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, the adjusting assembly 30 includes two hydraulic cylinders 31 installed on the side of the support frame 12. The output end of the hydraulic cylinder 31 passes through the support frame 12 and is connected to the hydraulic rod 32. The hydraulic rod 32 is connected with a lower pressing roller 34 through a connecting sleeve 33 at the bottom, and the connecting sleeve 33 is fixedly connected to the lower pressing roller 34; To facilitate the flexible adjustment of the pressure between the embossing roller 27 and the lower pressing roller 34, the hydraulic cylinder 31 can be started. The hydraulic cylinder 31 will drive the hydraulic rod 32 to move upward. As the hydraulic rod 32 rises, the connecting sleeve 33 connected to it will also move synchronously. During the rising process of the connecting sleeve 33, it will drive the lower pressing roller 34 to rise together, thereby increasing the distance between the lower pressing roller 34 and the embossing roller 27. At this time, the pressure between the embossing roller 27 and the lower pressing roller 34 will decrease accordingly; Conversely, if it is necessary to increase the pressure, the hydraulic cylinder 31 is driven to drive the hydraulic rod 32 to move downward. When the hydraulic rod 32 descends, it will synchronously drive the connecting sleeve 33 to move downward. During the descending process of the connecting sleeve 33, it will pull the lower pressing roller 34 to descend, thereby reducing the distance between the lower pressing roller 34 and the embossing roller 27, and increasing the pressure between the embossing roller 27 and the lower pressing roller 34.

[0021] As Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown in the figure, a detection component 40 is installed on one side of the support frame 12. The detection component 40 includes an inclined pressure rod 41 fixedly installed at the bottom of the lower pressure roller 34 in the adjustment component 30, and an extension rod 42 fixedly connected to one side of the support frame 12. An installation block 43 is fixedly connected to one side of the extension rod 42. A chute 431 is formed inside the installation block 43. A slider 44 is slidably connected to the inner wall of the installation block 43. One side of the slider 44 is connected to a contact block 45 that abuts against the inclined pressure rod 41. A limiting plate is connected to one side of the contact block 45. The slider 44 and the chute 431 are connected by an elastic member. The elastic member includes a positioning rod 46 fixedly connected to the inner wall of the chute 431. A moving plate 461 slidably connected to the positioning rod 46 is fixedly connected to one side of the slider 44. A telescopic spring 462 is sleeved on the outer periphery of the positioning rod 46. A scale line 47 is arranged on one side of the installation block 43. A pointer 48 is connected to the top of the slider 44; When the lower pressure roller 34 descends, it will synchronously drive the inclined pressure rod 41 to descend together. During the descent of the inclined pressure rod 41, it will abut against the contact block 45, and then push the slider 44 to slide inside the installation block 43. As the slider 44 moves, on the one hand, it will drive the moving plate 461 to slide on the outer periphery of the positioning rod 46 and compress the telescopic spring 462, and on the other hand, it will drive the pointer 48 to move synchronously, so that the pointer 48 points to the scale line 47. At this time, the operator can judge whether the lower pressure roller 34 is in a horizontal state by observing whether the left and right pointers 48 are on the same scale line 47. If it is found that the lower pressure roller 34 is not in the same horizontal position, different hydraulic cylinders 31 can be started to drive the corresponding hydraulic rods 32 to rise and fall, so as to further adjust the levelness of the lower pressure roller 34; On the contrary, when the lower pressure roller 34 rises, it will synchronously drive the inclined pressure rod 41 to rise together. At this time, the previously compressed telescopic spring 462 starts to rebound, pushing the moving plate 461 to slide on the outer periphery of the positioning rod 46. As the moving plate 461 moves, it synchronously drives the slider 44 to move, so that the contact block 45 always remains in contact with the inclined pressure rod 41. At the same time, the movement of the slider 44 will also drive the pointer 48 to move synchronously, so that the pointer 48 points to the scale line 47. Similarly, the operator judges whether the lower pressure roller 34 is in a horizontal state by observing whether the left and right pointers 48 are on the same scale line 47.

[0022] Such as Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 、 Figure 10As shown in the figure, a pushing component 50 is installed on one side of the slider 44. The pushing component 50 includes a fixing frame 51 fixedly connected to one side of the slider 44. An installation rod 511 is fixedly connected to the inner wall of the fixing frame 51. The installation rod 511 is rotatably connected to a rotating plate 52 through a torsion spring 512 sleeved on the outer periphery. An avoidance groove 513 is formed on the side surface of the installation block 43. A telescopic component in contact with the rotating plate 52 is fixedly connected to the side surface of the installation block 43. The telescopic component includes an L-shaped plate 53 fixedly connected to the bottom of the installation block 43. A plurality of pushing rods 54 are slidably connected to the inner wall of the L-shaped plate 53. An arc-shaped plate 55 is fixedly connected to one side of the plurality of pushing rods 54. Pressure springs 56 are sleeved on the outer peripheries of two of the pushing rods 54. The elastic force of the torsion spring 512 is greater than the elastic forces of the two pressure springs 56. Each pushing rod 54 is connected to a contact plate 57 through an internal extrusion component. The extrusion component includes a groove 58 formed inside the pushing rod 54. A moving rod 582 connected to the contact plate 57 is slidably connected to the inner wall of the groove 58. An extrusion spring 584 is connected between the moving rod 582 and the groove 58. A slot 581 is formed through the outer periphery of the groove 58. A measuring rod 583 extending out of the slot 581 is fixedly connected to the outer periphery of the moving rod 582. The measuring rod 583 is slidably connected to the slot 581; After the pattern roller 27 performs embossing operations for a long time, deformation may occur. To facilitate the detection of the outer periphery of the pattern roller 27, the servo motor 23 needs to be started first. After the servo motor 23 is started, it drives the pattern roller 27 to rotate. Then, the hydraulic cylinder 31 is started to drive the hydraulic rod 32 to descend. As the hydraulic rod 32 descends, the connecting sleeve 33 moves synchronously, thereby driving the lower pressing roller 34 to descend. While the lower pressing roller 34 descends, it drives the inclined pressing rod 41 to descend together. When the inclined pressing rod 41 descends, it presses against the abutting block 45, pushing the slider 44 to slide within the installation block 43; During the movement of the slider 44, on the one hand, it drives the moving plate 461 to slide on the outer periphery of the positioning rod 46 and squeezes the telescopic spring 462. On the other hand, it drives the fixing frame 51 to move. The fixing frame 51 pushes the rotating plate 52 to move through the installation rod 511. At this time, the rotating plate 52 is within the installation block 43, and the torsion spring 512 is in a compressed state. When the limiting plate on one side of the abutting block 45 comes into contact with the installation block 43 as it moves, the slider 44 cannot continue to slide. At this time, the rotating plate 52 just moves to one side of the avoidance groove 513 and is no longer restricted by the installation block 43. The torsion spring 512 in the compressed state starts to rebound, driving the rotating plate 52 to rotate by ninety degrees; When the rotating plate 52 rotates, it will push the arc-shaped plate 55 to move. The arc-shaped plate 55 drives several push rods 54 to move within the L-shaped plate 53, and at the same time squeezes the compression spring 56. During the movement of the push rod 54, under the action of the elastic force of the compression spring 584, it drives the moving rod 582 to move, so that the moving rod 582 drives the contact plate 57 to move towards the pattern roller 27 until it is in contact with the pattern roller 27. If the rotating pattern roller 27 is not deformed, several contact plates 57 will not move. If the rotating pattern roller 27 is deformed, the deformed part will push the contact plate 57, causing the contact plate 57 to drive the moving rod 582 to move within the groove 58 and press against the compression spring 584. At the same time, the moving rod 582 will drive the measuring rod 583 to move within the slot 581. The operator can judge the degree of deformation and damage of the pattern roller 27 by observing the movement of the measuring rod 583; If it is not necessary to detect the pattern roller 27, the hydraulic cylinder 31 is started to drive the hydraulic rod 32 to rise. As the hydraulic rod 32 rises, the connecting sleeve 33 moves synchronously, and then drives the lower pressure roller 34 to rise. While the lower pressure roller 34 rises, it drives the inclined pressure rod 41 to rise together. At this time, the stretched spring 462 in the compressed state starts to rebound, pushing the moving plate 461 to slide on the outer periphery of the positioning rod 46, and then driving the slider 44 to move. When the slider 44 moves, it drives the abutting block 45 to always be in contact with the inclined pressure rod 41 and drives the fixed frame 51 to move together. The originally bent rotating plate 52 is pulled by the mounting rod 511 into the mounting block 43 and rotates to be in the same straight line as the slider 44, and at the same time squeezes the torsion spring 512. When the rotating plate 52 no longer abuts against the arc-shaped plate 55, the compression spring 56 in the compressed state starts to rebound, pushing the arc-shaped plate 55 to reset. The arc-shaped plate 55 pulls the push rod 54 to move together, and the push rod 54 pulls the moving rod 582 connected to the compression spring 584, so that the moving rod 582 drives the contact plate 57 away from the pattern roller 27.

[0023] Working principle: When performing embossing operation on the paper box, the servo motor 23 needs to be started first. After the servo motor 23 is started, its output shaft rotates, driving the pulley 25 installed on the outer periphery of the output shaft to rotate, and then moving the belt 26 connected to it. Under the driving action of the belt 26, the pulley 25 on the outer periphery of the rotating shaft 24 also starts to rotate, driving the rotating shaft 24 to rotate synchronously and driving the pattern roller 27 connected to it to rotate. At this time, the pattern roller 27 and the lower pressure roller 34 in the adjusting assembly 30 cooperate with each other to apply pressure to the paper box to complete the embossing operation; In order to flexibly adjust the pressure between the pattern roller 27 and the lower pressing roller 34, the hydraulic cylinder 31 can be started. The hydraulic cylinder 31 drives the hydraulic rod 32 to move upward, driving the connecting sleeve 33 connected to it to rise, and then the lower pressing roller 34 rises together, increasing the distance between the lower pressing roller 34 and the pattern roller 27. At this time, the pressure between the two decreases. Conversely, the hydraulic cylinder 31 drives the hydraulic rod 32 to move downward, and the connecting sleeve 33 drops accordingly, pulling the lower pressing roller 34 down, reducing the distance between the lower pressing roller 34 and the pattern roller 27, and increasing the pressure between the two. When the lower pressure roller 34 descends, it will synchronously drive the inclined pressure rod 41 to descend, abutting the abutment block 45, pushing the slider 44 to slide in the mounting block 43. When the slider 44 moves, on the one hand, it drives the movable plate 461 to slide around the periphery of the positioning rod 46, squeezing the telescopic spring 462, and on the other hand, it drives the pointer 48 to move synchronously so that it points to the scale line 47. The operator judges whether the lower pressure roller 34 is horizontal by observing whether the left and right pointers 48 are on the same scale line 47. If they are not at the same horizontal position, the operator can start different hydraulic cylinders 31 to drive the corresponding hydraulic rods 32 to move up and down to adjust the horizontality of the lower pressure roller 34. After a long period of embossing, the pattern roller 27 may be deformed. To facilitate the inspection of its peripheral condition, the servo motor 23 must be started first to drive the pattern roller 27 to rotate, and then the hydraulic cylinder 31 is started to drive the hydraulic rod 32 to descend, thereby lowering the connecting sleeve 33 and the lower pressing roller 34. At the same time, the inclined pressing rod 41 is driven downward to abut the abutment block 45, pushing the slider 44 to slide in the mounting block 43. During the movement of the slider 44, on the one hand, it drives the movable plate 461 to slide around the periphery of the positioning rod 46, squeezing the telescopic spring 462, and on the other hand, it drives the fixed frame 51 to move. The fixed frame 51 pushes the rotating plate 52 to move via the mounting rod 511. At this time, the rotating plate 52 is inside the mounting block 43, and the torsion spring 512 is in a squeezed state. When the limiting plate on the side of the abutment block 45 contacts the mounting block 43, the slider 44 cannot slide further, and the rotating plate 52 just moves to the side of the avoidance groove 513, no longer restricted by the mounting block 43. The squeezed torsion spring 512 rebounds, driving the rotating plate 52 to rotate 90 degrees. When the rotating plate 52 rotates, it presses against the arc-shaped plate 55 to move, driving a number of push rods 54 to move within the L-shaped plate 53, squeezing the compression spring 56. During the movement of the push rod 54, under the elastic force of the compression spring 584, it drives the moving rod 582 to move, causing the moving rod 582 to drive the contact plate 57 towards the pattern roller 27 until it is in contact with the pattern roller 27. If the rotating pattern roller 27 is not deformed, a number of contact plates 57 will not move. If deformation occurs, the deformed part will push the contact plate 57, causing the contact plate 57 to drive the moving rod 582 to move within the groove 58, pressing against the compression spring 584, and at the same time driving the measuring rod 583 to move within the slot 581. The operator can judge the degree of deformation and damage of the pattern roller 27 by observing the movement of the measuring rod 583.
