Description

Technical Field

[0001] The present invention belongs to the field of die-cutting machines, and relates to a pressing device, in particular to a micro combined variable-position material pressing device for a satellite machine. Background Art

[0002] At present, when a die-cutting machine is working in processes such as installation, debugging, and production, the traditional ordinary material-passing small shaft method is adopted for material pressing and material input and output. Since the existing material-passing small shaft has no gear transmission device and only rotates passively, the friction force during the rotation and transmission of the material all comes from the friction between the material and its surface. During the input and output processes of the material, situations such as jitter, slipping, air bubbles, wrinkles, bending, and unstable tension will occur.

[0003] In addition, the pressing shaft installed on the main shaft of the die-cutting machine, although it belongs to gear transmission, due to the large external dimensions of the existing pressing shaft, it cannot be installed in a narrow space, and the operation is very inflexible and inconvenient. Moreover, the existing pressing shafts cannot be installed overlappingly. When using the stacked knife process and feeding materials into the middle, the reason why the existing pressing shafts cannot complete the operation is mainly that the overlapping use space is not allowed, so that no material-passing space can be generated at the bottom to perform secondary rolling on the material, thereby resulting in poor product dimensions and appearance. Summary of the Invention

[0004] The purpose of the present invention is to provide a micro combined variable-position material pressing device for a satellite machine with a scientific and reasonable structural design, stable material input and output, convenient installation, meeting process requirements, improving product precision, reducing the rejection rate, and being easy to implement.

[0005] The present invention solves its technical problems through the following technical solutions:

[0006] A micro combined variable-position material pressing device for a satellite machine, characterized in that it is composed of a variable-position convex rubber pressing shaft and a variable-position groove material-passing bottom shaft arranged up and down. The variable-position convex rubber pressing shaft is composed of a pressing shaft core, a rubber shaft sleeve, a guiding and locking bearing slider, a negative variable-position gear, a guiding bearing slider and a connecting and locking end cover. A rubber shaft sleeve is sleeved on the pressing shaft core. One end of the pressing shaft core is provided with a guiding and locking bearing slider through a connecting and locking end cover. A negative variable-position gear is installed at the other end of the pressing shaft core. A guiding bearing slider is installed at the outer end of the negative variable-position gear through a connecting and locking end cover. The variable-position groove material-passing bottom shaft is composed of a material-passing bottom shaft core, a guiding and locking bearing slider, a connecting and locking end cover, a positive variable-position gear and a guiding bearing slider. One end of the material-passing bottom shaft core is provided with a guiding and locking bearing slider through a connecting and locking end cover. A positive variable-position gear is installed at the other end of the material-passing bottom shaft core. A guiding bearing slider is installed at the outer end of the positive variable-position gear through a connecting and locking end cover. The positive variable-position gear and the negative variable-position gear are meshed.

[0007] Moreover, the middle part of the pressing shaft core is a structure composed of convex rubber and pressing shaft roller pillows coaxially arranged at both ends of the convex rubber; the middle part of the material-passing bottom shaft core is a structure composed of a bottom shaft groove and bottom shaft roller pillows coaxially arranged at both ends of the bottom shaft groove.

[0008] The advantages and beneficial effects of the present invention are as follows:

[0009] 1. This micro combined variable-position material pressing device for a satellite machine, by combining the variable-position convex rubber pressing shaft and the variable-position groove material-passing bottom shaft, solves the problem that the current ordinary material-passing small shaft can neither be used simultaneously nor be compatible for installation and use under various complex transformation processes, which affects both the installation and debugging time and the debugging effect. After adopting this device, it can be used for ordinary pressing materials and can be flexibly used for installation and debugging compatible with various processes, effectively solving the compatibility problem during complex processes and when changing debugging methods during process debugging, and effectively improving performance, efficiency and operability.

[0010] 2. The satellite machine uses a micro-combined variable position material pressing device, which adopts a micro-combined design. That is, before this solution is adopted, the existing traditional accessories cannot be used in the auxiliary station between the two main stations to implement the stacking process at the same time. Before the material is input, the pressing, compounding, and stabilizing the tension process can only be carried out by the traditional process. At this time, the tension is unstable and the compounding effect is not ideal, which will affect the product quality; secondly, if the existing larger type of shaft is installed in other main stations for material pressing and input, first, the distance will be far and the effect will be unsatisfactory. Second, the position of the main station will be occupied, making it impossible to install other tools and accessories. After adopting this device, the above problems are perfectly solved, effectively improving the installation of complex processes under the premise of small space and saving other stations to install more tools to complete more complex products. At the same time, when the feeding distance is close to the main tool, the material tension is stable enough, which directly improves the quality of the product.

[0011] 3. The satellite machine uses a micro-combined displacement material pressing device, which adopts a high-low difference roller design. That is, before this solution is adopted, the traditional method is to use the stacking knife process to press the material before feeding, or to use one of the traditional accessories to feed the material. This method is to stack two ordinary pressing shafts. This will cause the bottom pressing shaft to be forced to perform a second rolling on the material without the need for pressing. This will destroy the tension coordination problem on the main shaft, or cause wrinkles, deformation, and size mutation problems. After adopting this solution, a material gap is directly generated between the bottom shaft and the main shaft. This gap allows the material that does not need to be rolled to pass smoothly in this space. In this way, the material can be pressed before the stacking knife process, and the material can pass smoothly, solving the problem and improving product quality and efficiency.

[0012] 4. The satellite machine uses a micro-combined displacement material pressing device with a theoretical diameter concave-convex structural design. Before this solution was adopted, the traditional concave-convex form of feeding only produced a concave-convex effect on the surface. In fact, the internal dimensions were not accurately calculated and matched. At that time, the feeding speed was not coordinated and did not match the overall tension system, resulting in the material being loose or tight. This not only affects the size and appearance, but also leads to the inability to produce normally. The material contact position used in this solution can achieve pressing in the groove and realize the calculation method of synchronous size and tension, which prevents the occurrence of the above situation and effectively solves various problems caused by mismatched calculations during feeding. While improving the problems, it also improves the operability of the equipment.

[0013] 5. The micro combined variable-position material pressing device for satellite machines adopts a variable-position gear design. Before this solution was adopted, when only ordinary grooved shafts and ordinary pressing shafts were used for pressing, in order to avoid feeding problems, only a theoretical diameter concave-convex structural design was simply adopted, without cooperating with this design solution, which would directly lead to insufficient meshing of the gears during operation and then direct damage. After adopting this solution, the necessary processing parameters of the gears can be scientifically designed and changed according to the increase and decrease of the required diameter. In this way, not only can the number of teeth remain unchanged, but also the positive variable-position gear can be used to effectively eliminate the clearance of insufficient meshing, and at the same time, the negative variable-position gear is used to eliminate the clearance generated after the positive variable-position gear is displaced, achieving effective protection of the equipment gears while improving product quality and equipment stability.

[0014] 6. The design of the present invention is scientific and reasonable, having the advantages of stable material input and output, convenient installation, meeting process requirements, improving product accuracy, reducing the rejection rate, and being easy to implement. It is a micro combined variable-position material pressing device for satellite machines with high innovation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0025] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited thereby.

[0026] A miniature combined modified material pressing device for satellite machine, the innovation of which lies in: it is composed of a modified convex rubber pressing shaft 4 and a modified groove material passing bottom shaft 5 arranged up and down. The modified convex rubber pressing shaft is composed of a pressing shaft core 7, a rubber shaft sleeve 8, a guide locking bearing slider 6, a negative modified gear 2, a guide bearing slider 1 and a connecting locking end cover 9. A rubber shaft sleeve is sleeved on the pressing shaft core. One end of the pressing shaft core is provided with a guide locking bearing slider through a connecting locking end cover. A negative modified gear is installed at the other end of the pressing shaft core. A guide bearing slider is installed at the outer end of the negative modified gear through a connecting locking end cover. The modified groove material passing bottom shaft is composed of a material passing bottom shaft core 10, a guide locking bearing slider, a connecting locking end cover, a positive modified gear 3 and a guide bearing slider. One end of the material passing bottom shaft core is provided with a guide locking bearing slider through a connecting locking end cover. A positive modified gear is installed at the other end of the material passing bottom shaft core. A guide bearing slider is installed at the outer end of the positive modified gear through a connecting locking end cover. The positive modified gear and the negative modified gear are meshed.

[0027] The middle part of the pressing shaft core is a structure composed of a convex rubber 12 and pressing shaft roller pillows 11 coaxially arranged at both ends of the convex rubber. The middle part of the material passing bottom shaft core is a structure composed of a bottom shaft groove 14 and bottom shaft roller pillows 13 coaxially arranged at both ends of the bottom shaft groove.

[0028] During installation, first install the assembled variable-position groove material-passing bottom shaft I at the auxiliary station of the satellite main workstation; then engage and connect the variable-position groove material-passing bottom shaft with the main shaft H of the satellite main workstation, and at the same time adjust the gap e between the variable-position groove material-passing bottom shaft and the main shaft, the gap g between the bottom shaft bolster and the main shaft, and the gap i between the positive variable-position gear and the gear on the main shaft according to the process requirements; then install the variable-position convex rubber pressing shaft J above the variable-position groove material-passing bottom shaft I through the auxiliary station of the satellite main workstation A to make them connected and engaged; adjust the gap f between the convex rubber and the bottom shaft groove, the gap h between the pressing shaft bolster and the bottom shaft bolster, and the gap j between the positive variable-position gear and the negative variable-position gear according to the process to make the variable-position groove material-passing bottom shaft I and the variable-position convex rubber pressing shaft J reach the best meshing state; finally, use the installation device above the variable-position convex rubber pressing shaft to adjust and lock the pressure.

[0029] Working principle:

[0030] 1. Before the input material D enters the die-cutting process between the main shaft cutter C and the matching cutting material-passing groove roller B, it first passes through the gap f between the convex rubber and the bottom shaft groove of the satellite machine's micro combined variable-position material pressing device F for material pressing;

[0031] 2. The pressed material can be directly die-cut, or the waste part that needs to be removed can be removed before die-cutting;

[0032] 3. The bottom shaft groove of the variable-position groove material-passing bottom shaft I is designed with the theoretical diameter of the corresponding number of teeth, so that there will be no difference in the material feeding speed;

[0033] 4. The diameter of the bottom shaft bolster of the variable-position groove material-passing bottom shaft I is increased to form the bottom shaft groove in the middle of the bottom shaft, and when used in combination, the material-passing gap e between the variable-position groove material-passing bottom shaft and the main shaft is generated;

[0034] 5. Then, positive variable-position compensation is carried out through the positive variable-position gear. Due to the gear meshing gap i between the positive variable-position gear and the gear on the main shaft generated by the enlarged diameter at the bottom shaft bolster, it can not only generate the material-passing gap e between the variable-position groove material-passing bottom shaft and the main shaft, but also ensure that the material synchronism is not affected, and it does not affect the normal gear meshing and transmission;

[0035] 6. The convex rubber part of the variable-position convex rubber pressing shaft J is designed with the theoretical diameter of the corresponding number of teeth, so that there will be no difference in the material feeding speed;

[0036] 7. The diameter of the pressing shaft bolster of the variable-position convex rubber pressing shaft J is reduced to generate the rubber convex part at the convex rubber c. When used in combination, the gap f between the convex rubber and the bottom shaft groove is generated to achieve the concave-convex matching material pressing state;

[0037] 8. Then, negative modification compensation is carried out through the negatively modified gear. Due to the clearance j between the positively modified gear and the negatively modified gear caused by the decrease in the diameter at the pillow of the pressing shaft roller, it can achieve both the state of pressing the concave-convex fitting material at the clearance f between the raised rubber and the bottom shaft groove, and the synchronism of the material is not affected, and it does not affect the normal gear meshing and transmission. Subsequently, the waste material E to be extracted is output from the rear of the satellite machine used micro combined modified material pressing device F.

[0038] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art can understand that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the content disclosed in the embodiments and drawings.
