Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of circular knife die cutting machine equipment, in particular to a roller pressing, peeling and hot pressing integrated device. Background Art
[0002] After the circular die-cutting machine completes the die-cutting operation on the material strip, the waste generated by the die-cutting needs to be peeled off in time to facilitate the subsequent production process of the product. Before peeling off the waste, a layer of support film needs to be pressed on the bottom or top of the material strip to prevent the material strip from falling off.
[0003] The main problem with the existing die-cutting device is that the knife holder is only equipped with a heated rubber roller for hot pressing the material strip, and the rolling and peeling mechanisms can only be installed on a separate knife holder. This not only lengthens the product production line and causes the equipment to occupy a relatively large space, but also the manufacturing cost of the knife holder is very high, resulting in very high equipment cost investment in production.
[0004] Therefore, a rolling peeling and hot pressing integrated device is needed to solve the above problems. Utility Model Content
[0005] The utility model provides a rolling, peeling and hot pressing integrated device, which integrates rolling, peeling and hot pressing into one device, shortens the production line length of the product, reduces the volume of the equipment, and greatly reduces the cost investment of the equipment.
[0006] The technical solution of the utility model is achieved in this way:
[0007] The roller-pressing and hot-pressing integrated device comprises a pair of vertical plates fixed to one side of a knife seat, a horizontally arranged lower pressure roller is rotatably mounted on the two vertical plates, an upper pressure roller is arranged directly above the lower pressure roller, and a spacing fine-tuning mechanism is arranged between the two ends of the upper pressure roller and the corresponding vertical plates, and the spacing fine-tuning mechanism is used to fine-tune the vertical movable distance of the upper pressure roller, a material guide roller is arranged above the upper pressure roller, and the material guide roller is extended along the axial direction of the lower pressure roller, and the two ends of the material guide roller are respectively rotatably mounted on the corresponding vertical plates;
[0008] A stripping knife is arranged on the discharge side of the upper pressure roller, both ends of the stripping knife are connected to the vertical plate through a mounting frame, an angle adjustment mechanism is arranged between the stripping knife and the mounting frame, and the angle adjustment mechanism is used to adjust the inclination angle of the stripping knife.
[0009] As a preferred technical solution, the angle adjustment mechanism includes a horizontal axis installed on the mounting frame, the horizontal axis extending along the axial direction of the lower pressure roller, a pair of sleeves slidably installed on the horizontal axis, each sleeve is provided with an opening clip, each opening clip is sleeved on the horizontal axis, both ends of each opening clip are locked by a locking bolt, and both ends of the stripping knife are fixedly installed on the corresponding sleeve.
[0010] As a preferred technical solution, each of the spacing fine-tuning mechanisms includes an axle seat, both ends of the upper pressure roller are rotatably mounted on the corresponding axle seat, each of the axle seats is slidably mounted on the corresponding vertical plate along the vertical direction, a return spring is commonly installed between the bottom of each axle seat and the corresponding vertical plate, a limiting screw is arranged directly above each axle seat, and each of the limiting screws is mounted on the corresponding vertical plate along a vertical thread.
[0011] As a preferred technical solution, the mounting frame includes two oppositely arranged support arms, each of the support arms is arranged on the outer side of the corresponding vertical plate, one end of each of the support arms is installed on the corresponding vertical plate, and the other end of each of the support arms is fixedly connected to the horizontal axis.
[0012] As a preferred technical solution, each of the vertical plates is provided with a vertically arranged guide groove, the position of each guide groove corresponds to the position of the axle seat, each axle seat is slidably installed in the guide groove, and the lower end of each limit screw extends into the guide groove.
[0013] By adopting the above technical solution, the beneficial effects of the utility model are as follows:
[0014] Since the integrated rolling, stripping and hot pressing device includes a knife seat and a vertical plate, an upper pressing roller, a lower pressing roller and a stripping knife are installed on the vertical plate. In the utility model, the upper pressing roller, the lower pressing roller and the stripping knife are hung on the feed side of the knife seat through the vertical plate, and a heating rubber roller for hot pressing the material strip is installed on the knife seat. The utility model integrates the rolling, stripping and hot pressing work into one knife seat to complete, and no additional knife seat is required to install the upper pressing roller and the lower pressing roller, thereby reducing the number of knife seats in the production line and reducing the cost investment of equipment in the production line; and in the traditional stripping process, the stripping knife is far away from the rolling and hot pressing stations, resulting in the need to set the knife arm of the stripping knife to be very long, which occupies a relatively large space, while the stripping knife in the utility model is tightly arranged between the knife seat and the pressure roller, effectively shortening the production line length of the product production.
[0015] Since the upper and lower pressure rollers are arranged up and down, a stripping knife is arranged on the discharge side of the lower pressure roller, and a material guide roller is arranged above the upper pressure roller. In the utility model, the material belt and the support film pass through the rolling gap between the upper and lower pressure rollers at the same time, and the material belt and the support film are rolled so that the support film fits the bottom of the material belt. After passing through the rolling gap, the material belt and the support film continue to move forward and pass through the heated rubber roller on the knife holder, and the waste on the material belt will bypass the stripping knife for waste stripping, thereby avoiding the situation that the waste is difficult to separate from the material belt after hot pressing, thereby realizing the integrated setting of rolling, stripping and hot pressing, and the rolling, stripping and hot pressing processes can be completed on one knife holder, thereby shortening the production line length of the product production, and then greatly reducing the size of the equipment.
[0016] Since a spacing fine-tuning mechanism is provided between the upper pressure roller and the vertical plate, the spacing fine-tuning mechanism includes a shaft seat, a return spring and a limit screw. In the utility model, the spacing fine-tuning mechanism can fine-tune the movable range of the upper pressure roller in the vertical direction, so that the upper pressure roller can move slightly in the vertical direction. Since the thickness of the material strip is not the same at different places after the previous processing, the movable upper pressure roller can roll both the thicker and thinner positions on the material strip. At the same time, the staff can adjust the screw-in length of the limit screw according to the thickness size at the thickest position of the material strip. The setting of the return spring ensures that the upper pressure roller is always tightly pressed against the upper surface of the material strip.
[0017] Since an angle adjustment mechanism is provided between the stripping knife and the mounting frame, in the utility model, the setting of the angle adjustment mechanism can adjust the inclination angle of the stripping knife, and the force of the stripping knife pressing on the material belt can be adjusted by adjusting the inclination angle, so that the utility model is suitable for the waste stripping work of different types of materials, which avoids the situation that the material belt is damaged due to excessive stripping force, and also avoids the situation that the waste stripping cannot be completed due to insufficient stripping force.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figure 1-Figure 4 As shown together, the roller-pressing, peeling and hot-pressing integrated device comprises a pair of vertical plates 2 fixed to one side of a knife seat 1, and a horizontally arranged lower pressure roller 3 is rotatably mounted on the two vertical plates 2, and an upper pressure roller 4 is arranged directly above the lower pressure roller 3. In the utility model, the upper pressure roller 4, the lower pressure roller 3 and the peeling knife 5 are hung on the feed side of the knife seat 1 through the vertical plates 2, and a heating rubber roller 9 for hot-pressing the material strip 8 is installed on the knife seat 1; a spacing fine-tuning mechanism is arranged between the two end portions of the upper pressure roller 4 and the corresponding vertical plates 2, and the spacing fine-tuning mechanism is used to fine-tune the vertical movable distance of the upper pressure roller 4, and a material guide roller 7 is arranged above the upper pressure roller 4, and the material guide roller 7 is extended along the axial direction of the lower pressure roller 3, and the two ends of the material guide roller 7 are respectively rotatably mounted on the corresponding vertical plates 2.
[0026] Among them, a stripping knife 5 is arranged on the discharge side of the upper pressure roller 4, and both ends of the stripping knife 5 are connected to the vertical plate 2 through a mounting frame, and an angle adjustment mechanism is arranged between the stripping knife 5 and the mounting frame, and the angle adjustment mechanism is used to adjust the inclination angle of the stripping knife 5. In this embodiment, the utility model integrates the rolling, stripping and hot pressing work into a knife seat 1 to complete, and no additional knife seat 1 is required to install the upper pressure roller 4 and the lower pressure roller 3, thereby reducing the number of knife seats 1 in the production line and reducing the cost investment of equipment in the production line; and in the traditional stripping process, the stripping knife 5 is far away from the rolling and hot pressing stations, resulting in the need for the knife arm of the stripping knife 5 to be set very long, which occupies a relatively large space, and the stripping knife 5 in the utility model is tightly arranged between the knife seat 1 and the pressure roller, which effectively shortens the production line length of the product production.
[0027] In the present invention, the rolling, peeling and hot pressing process of the material strip 8 is as follows:
[0028] First, the material strip 8 and the support film 10 are rolled together through the rolling gap between the upper pressing roller 4 and the lower pressing roller 3, and the support film 10 is pressed on the bottom of the material strip 8; then, the waste material 11 on the upper surface of the material strip 8 is pulled away by the guide roller 7, and the remaining part passes through the two heated rubber rollers 9 together. At the same time, the stripping knife 5 is pressed against the upper surface of the material strip 8. As the material strip 8 continues to move forward, the stripping knife 5 will smoothly strip the waste material 11 from the material strip 8.
[0029] The utility model realizes the integrated setting of rolling, stripping and hot pressing, and the rolling, stripping and hot pressing processes can be completed on one knife seat, thereby shortening the production line length of product production and greatly reducing the size of the equipment; moreover, before the material belt 8 enters the heated rubber roller 9, a layer of supporting film 10 is pressed on the lower surface of the material belt 8, and the waste material 11 is stripped off by the stripping knife 5, which not only avoids the situation that the waste material 11 is difficult to separate from the material belt 8 after hot pressing, but also avoids the situation that the material belt 8 is disconnected and caused to fall off, thereby ensuring the continuity of production work.
[0030] like Figure 1 As shown, the angle adjustment mechanism includes a transverse axis 12 installed on the mounting frame, the transverse axis 12 is extended along the axial direction of the lower pressure roller 3, a pair of sleeves 13 are slidably installed on the transverse axis 12, each sleeve 13 is provided with an open clip 14, each open clip 14 is sleeved on the transverse axis 12, and both ends of each open clip 14 are locked by locking bolts 15, and both ends of the stripping knife 5 are fixedly installed on the corresponding sleeve 13. In the utility model, the angle adjustment mechanism adjusts the stripping force of the stripping knife 5 on the waste 11 by adjusting the inclination angle of the stripping knife 5, so that the utility model is suitable for the stripping work of waste 11 of different types of materials, which not only avoids the damage of the material belt 8 due to excessive stripping force, but also avoids the failure to complete the stripping of the waste 11 due to insufficient stripping force.
[0031] The method for adjusting the inclination angle of the stripping knife 5 in the utility model is as follows:
[0032] Loosen the locking bolt 15 to unlock the opening clamp 14, so that the sleeve 13 can rotate relative to the horizontal axis 12. Then the staff rotates the sleeve 13 to adjust the inclination angle of the stripping knife 5. After adjustment, tighten the locking bolt 15 again to make the opening clamp 14 firmly clamp the horizontal axis 12 and lock the sleeve 13.
[0033] like Figure 1-Figure 3As shown together, each spacing fine-adjustment mechanism includes an axle seat 16, and both end portions of the upper pressure roller 4 are rotatably mounted on the corresponding axle seat 16. Each axle seat 16 is slidably mounted on the corresponding vertical plate 2 along the vertical direction. A return spring 17 is commonly installed between the bottom of each axle seat 16 and the corresponding vertical plate 2. A limiting screw 18 is provided directly above each axle seat 16, and each limiting screw 18 is installed on the corresponding vertical plate 2 along a vertical thread. In this embodiment, the return spring 17 adopts a tension spring.
[0034] In the utility model, the screw-in length of the limit screw 18 is used to limit the vertical movable distance of the upper pressure roller 4. Since the material strip 8 has different thicknesses after a series of processes such as cutting, transferring, and pressing in the previous production process, the movable upper pressure roller 4 can roll the thicker position of the material strip 8 as well as the thinner position of the material strip 8, thereby ensuring the rolling effect of the material strip 8 of the utility model. At the same time, the staff can adjust the screw-in length of the limit screw 18 according to the thickness of the thickest position of the material strip 8, and the setting of the reset spring 17 ensures that the upper pressure roller 4 is always tightly pressed against the upper surface of the material strip 8.
[0035] Moreover, the mounting frame includes two oppositely arranged support arms 19, each support arm 19 is arranged on the outer side of the corresponding vertical plate 2, one end of each support arm 19 is installed on the corresponding vertical plate 2, and the other end of each support arm 19 is fixedly connected to the horizontal axis 12.
[0036] In addition, each vertical plate 2 is penetrated by a vertical guide groove 6 , the position of each guide groove 6 corresponds to the position of the shaft seat 16 , each shaft seat 16 is slidably installed in the guide groove 6 , and the lower end of each limit screw 18 extends into the guide groove 6 .
[0037] In summary, the integrated rolling, peeling and hot pressing device proposed in the utility model integrates rolling, peeling and hot pressing into one device, shortens the production line length of the product, reduces the size of the equipment, and greatly reduces the cost investment of the equipment.
[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
