[0009] Furthermore, the molding mechanism includes a molding shell and a molding mold and a heating device arranged in the molding shell. The molding mold machine includes an outer mold and a mold core that are nested and used in conjunction with each other. The heating device is arranged between the outer mold and the molding shell.

[0010] Furthermore, the outer mold is provided with a rectangular through hole for the mold core to pass through, one end of the mold core is circular and the other end is a rectangular structure used in conjunction with the rectangular through hole, and the middle part is a transition area from circular to rectangular.

[0011] Furthermore, the circular end of the mold core is provided with an elbow for facilitating pulling out and replacing the mold core, and the heating device is an electric heating wire or an electric heating rod.

[0012] Furthermore, the feeding mechanism includes a feeding bracket, a feeding base plate, a feeding cylinder and a pressing cylinder. The feeding bracket is arranged on the bracket, and a cylindrical guide rail and a slider used therewith are arranged thereon. One end of the feeding cylinder is arranged on the slider, and the other end is arranged on the feeding bracket to realize the reciprocating sliding of the slider on the cylindrical guide rail.

[0013] Furthermore, the feed base plate is arranged on the slider, and the clamping cylinder is arranged on the feed base plate through a clamping bracket.

[0017] Furthermore, the auxiliary limiting device is a strip block with one end arranged on the bracket, and the other end of the strip block is provided with a strip hole for the pad paper before forming to pass through, and the storage box is placed on the bottom surface of the lower side of the cutting mechanism.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention arranges a feeding mechanism, a forming mechanism and a cutting mechanism that cooperate with each other on a bracket, pulls the pad paper through the forming mechanism for forming operation through the feeding mechanism, and pushes the formed pad paper into the cutting mechanism for cutting, thereby changing the existing manual bending and cutting into automatic bending and cutting, realizing the unification of shape standards, improving work efficiency and reducing the labor intensity of personnel.

[0020] 2. The present invention realizes the bending operation of the pad paper by using the outer mold and the mold core in combination, and realizes the shaping of the pad paper after bending by heating by the heating device, thus changing the previous manual bending into automatic bending, improving production efficiency and reducing labor intensity.

[0021] 3. The mold core of the present invention passes through the outer mold through a rectangular through hole and is used in conjunction with the outer mold. One end of the mold core is circular and the other end is a rectangular structure used in conjunction with the rectangular through hole. The middle part is a transition area from circular to rectangular, which realizes the gradual bending operation of the moving pad paper. The circular end of the mold core is provided with an elbow, which is convenient for pulling out and replacing the mold core.

[0022] 4. The present invention performs a pressing operation on the formed pad paper through a pressing cylinder, and then realizes the movement of the pad paper through the action of a feeding cylinder. Since the feeding mechanism is arranged between the forming mechanism and the cutting mechanism, the forming mechanism is pulled outward and the cutting mechanism is fed inward, thereby completing the feeding operation of both at the same time.

[0023] 5. A limit sensor is provided on the feed bracket of the present invention to limit the movable stroke of the feed cylinder, thereby limiting the feeding distance and ensuring that the pad paper fed to the cutting mechanism has the same length to achieve size unification. At the same time, the clamping cylinder drives the n-shaped clamping plate to move up and down, and is used in conjunction with the strip-shaped rectangular protrusion to achieve a clamping operation on the pad paper set on the strip-shaped rectangular protrusion. The n-shaped clamping plate is used in conjunction with the strip-shaped rectangular protrusion to form the same structure as the pad paper to prevent the pad paper from being deformed during the clamping and moving process.

[0024] 6. The present invention uses a cutting cylinder to drive the cutting knife to move back and forth on a slideway, and automatically cuts the pad paper fed by the feeding mechanism, thereby solving the problem of inconsistent cutting standards in manual cutting. At the same time, an n-shaped through hole is provided on the cutting vertical plate for the formed pad paper to pass through, thereby limiting the pad paper and facilitating the cutting operation.

[0025] 7. The auxiliary limiting device of the present invention is arranged on the bracket at the feeding end of the forming mechanism, and is provided with a strip hole for the pad paper before forming to pass through, so as to limit the pad paper and ensure the stability of the pad paper when entering the forming mechanism, prevent winding and deformation, and facilitate subsequent forming operations.

[0052] The feeding mechanism 2 includes a feeding bracket 201, a feeding base plate 202, a feeding cylinder 203 and a pressing cylinder 204. The feeding bracket 201 is arranged on the bracket 1, and is provided with a cylindrical guide rail 205 and a slider 206 used in conjunction with it. One end of the feeding cylinder 203 is arranged on the slider 206, and the other end is arranged on the feeding bracket 201, so as to realize the reciprocating sliding of the slider 206 on the cylindrical guide rail 205; the feeding base plate 202 is arranged on the slider 206, and the pressing cylinder 204 is arranged on the feeding base plate 202 through a pressing bracket 207. A strip-shaped rectangular protrusion 208 is arranged on the feeding base plate 202 on the lower side of the pressing cylinder 204, and a movable end of the pressing cylinder 204 is provided with an n-shaped pressing plate 209 used in conjunction with the strip-shaped rectangular protrusion 208; a limit sensor 210 for limiting the moving distance of the slider 206 is arranged on the feeding bracket 201.

[0053] The cutting mechanism 4 includes a cutting plate 401, a cutting cylinder 402 and a cutting knife 403. The cutting knife 403 is slidably set on the cutting plate 401 through a slide 404. The cutting cylinder 402 is set on the cutting plate 401 and connected to the cutting knife 403 to achieve reciprocating movement on the slide 404. The cutting plate 401 through which the cutting knife 403 reciprocates is provided with an n-shaped through hole 405 for the formed pad paper 6 to pass through.

[0054] The auxiliary limiting device 5 is a strip block 501 with one end arranged on the bracket 1 , and the other end of the strip block 501 is provided with a strip hole 502 for the pad paper 6 before forming to pass through.

[0055] When in use, the following operations are performed in advance: people pull the core mold 304 out of the outer mold 303 through the elbow 305 in advance, and then pass the pad paper 6 through the strip hole 502 on the auxiliary limiting device, the rectangular through hole 306 on the outer mold 303, between the strip rectangular protrusion 208 and the clamping plate 209, and the n-type through hole 405 on the cutting vertical plate 401 in sequence, and put the core mold 304 into the rectangular through hole 306 of the outer mold 303, and turn on the heating device 302 for heating.

[0056] Automatic bending and cutting operation: by pulling the feeding mechanism 2, the pad paper 6 passes through the auxiliary limiting device 5 and enters the forming mechanism 3 for forming operation, and then, under the push of the feeding mechanism 2, the formed pad paper 6 is pushed into the cutting mechanism 4 for cutting. The cut pad paper 6 falls into the storage box 7 for storage. The feeding mechanism 2 continuously moves to perform continuous bending and cutting operations on the pad paper 6.

[0057] Working process of the feeding mechanism: the clamping cylinder 204 is actuated, driving the clamping plate 209 to move and cooperate with the strip-shaped rectangular protrusion 208 to complete the clamping operation on the pad paper 6 passing therethrough, and the feeding cylinder 203 is actuated within the range of the limit sensor 210, so that the slider 206 drives the feeding bottom plate 202 to move, and through the cooperation between the feeding cylinder 203 and the clamping cylinder 204, the pad paper 6 is always moved toward the cutting mechanism 4.

[0058] Working process of the forming mechanism: After the pad paper 6 passes through the strip hole 502 on the strip block 501, it enters the bending gap formed between the mold core 304 and the outer mold 302. Under the pulling of the feeding mechanism 2 on the pad paper 6, the pad paper 6 gradually moves from the circular end to the rectangular end of the mold core 304, and passes through the rectangular through hole 306 to complete the automatic bending operation. Due to the heating of the heating device 302, the pad paper 6 is shaped after bending (the pad paper 6 increases its softness after being heated in the forming mechanism 3, which facilitates the bending operation. When the pad paper 6 leaves the forming mechanism 3, the temperature decreases to achieve the shaping operation).

[0059] Working process of the cutting mechanism: the feeding mechanism 2 feeds the formed pad paper 6 into the cutting vertical plate 401 through the n-shaped through hole 405, and then the cutting knife 403 moves along the slide 404 under the action of the cutting cylinder 402 to cut the pad paper 6 on the moving path, and the cut pad paper 6 falls into the storage box 7 for storage.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
