Description

Technical Field

[0001] The utility model relates to the technical field of die cutting machines, in particular to a pneumatic heating rubber roller. Background Art

[0002] In the process of producing and processing film products, according to the requirements of the production process, the material strips need to be cut, pressed and other operations to obtain the final product. Some material strips (such as hot melt adhesive film products) have strict temperature requirements and need to be hot pressed. The traditional hot pressing device mainly includes a knife seat, a transmission bottom shaft, a steel roller and a heating rubber roller, and the material strips are heated and pressed by the continuously rotating heating rubber roller.

[0003] In traditional hot pressing devices, the bearing box of the heating rubber roller is directly fixed on the knife seat, and its position can only be adjusted manually. After power failure, heat will remain on the surface of the heating rubber roller and continue to act on the material strip. This may not only cause damage to the material strip passing between the steel roller and the heating rubber roller, but also may cause insufficient hot pressing effect due to insufficient temperature, thus affecting subsequent production.

[0004] Therefore, a pneumatic heating rubber roller capable of solving the above problems is needed. Utility Model Content

[0005] The utility model provides a pneumatic heating rubber roller, which realizes the pneumatic adjustment of the position of the heating rubber roller and solves the problem of product production being affected by heat remaining on the surface of the heating rubber roller.

[0006] The technical solution of the utility model is achieved in this way:

[0007] The pneumatic heating rubber roller comprises a knife seat, a laterally arranged fixing seat is fixedly mounted on the upper end of the knife seat, a lifting plate is arranged directly below the fixing seat, the lifting plate is slidably mounted on the knife seat in a vertical direction, the two ends of the lifting plate are respectively fixedly connected to the bearing boxes at the two ends of the heating rubber roller, the lifting plate is connected to a position adjustment mechanism for pneumatically adjusting the height of the heating rubber roller, two vertically arranged micrometers are also arranged between the fixing seat and the lifting plate, the fixing sleeve of the micrometer is fixed on the fixing seat, and the micrometer screw of the micrometer is connected to the lifting plate.

[0008] As a preferred technical solution, at least one limiting block is fixed to the bottom of the fixing seat.

[0009] As a preferred technical solution, a spacer block is fixed on the top of each bearing box, and each spacer block is fixed on the lifting plate.

[0010] As a preferred technical solution, the position adjustment mechanism includes two vertically arranged cylinders, the cylinder body of each cylinder is fixed on the fixed seat, and the rod body of each cylinder is connected to the lifting plate.

[0011] As a preferred technical solution, the two micrometers and the two cylinders are symmetrically arranged relative to the middle position of the fixing seat.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0013] Since the pneumatic heating rubber roller includes a knife seat, a fixing seat, a lifting plate and a position adjustment mechanism, in the utility model, the cylinder in the position adjustment mechanism is used to drive the lifting plate to perform pneumatic lifting and lowering, thereby realizing automatic adjustment of the height position of the heating rubber roller, and being able to immediately raise the heating rubber roller after power failure, thereby solving the problem of subsequent production of products being affected by heat remaining on the heating rubber roller; at the same time, the utility model can directly utilize the existing heating rubber roller and connect it to the lifting plate by bolts, without the need to re-customize the heating rubber roller, thereby avoiding waste of the heating rubber roller and reducing the investment cost of the equipment.

[0014] Since two vertically arranged micrometers are provided between the fixed seat and the lifting plate, in the utility model, the setting of the micrometer serves to limit the lowest position of the lifting plate, thereby avoiding the situation in which the heating rubber roller, the steel roller and the transmission gear at the end are damaged due to the heating rubber roller descending too far, thereby achieving safety protection for the heating rubber roller, the steel roller and the transmission gear, and improving the operational safety of the utility model.

[0015] Since at least one limit block is fixed to the bottom of the fixed seat, in the utility model, the limit block is used to limit the highest position of the lifting plate, avoiding the lifting plate being too close to the fixed seat and causing impact damage to the cylinder and micrometer, thereby improving the operating safety of the utility model.

[0016] Since each bearing box and the lifting plate are fixedly connected by a spacer, in the utility model, the spacer is used to increase the distance between the lifting plate and the heating rubber roller, avoiding interference between the transmission gear at the end of the heating rubber roller and the lifting plate, thereby ensuring the normal rotation of the heating rubber roller.

[0022] 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.

[0023] like Figure 1-Figure 3 As shown in common, the pneumatic heating rubber roller includes a knife seat 1, a laterally arranged fixed seat 2 is fixedly installed on the upper end of the knife seat 1, a lifting plate 3 is arranged directly below the fixed seat 2, and the lifting plate 3 is installed on the knife seat 1 along the vertical sliding direction, and the two ends of the lifting plate 3 are respectively fixedly connected to the bearing boxes 5 at the two ends of the heating rubber roller 4, and the lifting plate 3 is connected to a position adjustment mechanism for pneumatically adjusting the height of the heating rubber roller 4. Two vertically arranged micrometers 6 are also arranged between the fixed seat 2 and the lifting plate 3, and the fixed sleeve of the micrometer 6 is fixed on the fixed seat 2, and the micrometer screw of the micrometer 6 is connected to the lifting plate 3. In the utility model, the setting of the micrometer 6 is used to limit the lowest position of the lifting plate 3, so as to avoid the lifting plate 3 from descending too far and interfering with the rotation of the heating rubber roller 4, thereby ensuring the safety of the use of the utility model.

[0024] Among them, at least one limit block 7 is fixed to the bottom of the fixed seat 2. In this embodiment, the limit block 7 is set to limit the highest position of the lifting plate 3, avoiding the lifting plate 3 from rising too far and causing impact damage to the cylinder 8 and the micrometer 6, thereby improving the safety of the use of the utility model.

[0025] like Figure 3As shown, a spacer block 9 is fixed on the top of each bearing box 5, and each spacer block 9 is fixed on the lifting plate 3. In this embodiment, the setting of the spacer block 9 increases the distance between the lifting plate 3 and the heating rubber roller 4, avoiding interference between the lifting plate 3 and the transmission gear 10, thereby ensuring the normal operation of the utility model and the heating rubber roller 4.

[0026] like Figure 1 and Figure 2 As shown in common, the position adjustment mechanism includes two vertically arranged cylinders 8, the cylinder body of each cylinder 8 is fixed on the fixed seat 2, and the rod body of each cylinder 8 is connected to the lifting plate 3. In the utility model, the cylinder 8 is used to drive the lifting plate 3 and the heating rubber roller 4 to automatically rise and fall, thereby realizing pneumatic adjustment of the position of the heating rubber roller 4, so that the heating rubber roller 4 can be immediately raised after the power is cut off, thereby avoiding the situation where the heat retained on the heating rubber roller 4 affects the material belt, thereby realizing the safety protection of the material belt.

[0027] In addition, the two micrometers 6 and the two cylinders 8 are symmetrically arranged relative to the middle position of the fixed base 2.

[0028] The method of using the utility model is as follows:

[0029] The first step is to adjust the micrometer 6 according to the specifications of the heating rubber roller 4 and the steel roller 11, and control the rod of the cylinder 8 to extend downward, drive the lifting plate 3 and the heating rubber roller 4 to fall, so that the transmission gears 10 on the heating rubber roller 4 and the steel roller 11 are meshed with each other;

[0030] In the second step, the material strip passes between the heating rubber roller 4 and the steel roller 11, and the servo motor 12 is started. The servo motor 12 drives the bottom shaft 13 to rotate, and drives the steel roller 11 and the heating rubber roller 4 to rotate in turn through the transmission gear 10, and the material strip is hot-pressed by the continuously rotating heating rubber roller 4;

[0031] The third step is to cut off the power supply to the heating rubber roller 4, retract the rod of the cylinder 8 upward, drive the lifting plate 3 and the heating rubber roller 4 upward, and separate the heating rubber roller 4 from the steel roller 11. At this time, the heating rubber roller 4 no longer performs hot pressing work on the material strip.

[0032] In summary, the pneumatic heating rubber roller proposed in the utility model realizes the pneumatic adjustment of the position of the heating rubber roller 4, and solves the problem of product production being affected by heat remaining on the surface of the heating rubber roller 4.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
