Description

Technical Field

[0001] The invention belongs to the technical field of automated production equipment and relates to a splitting mechanism on a cover packaging machine. Background Art

[0002] The watch cover is a round thin sheet with a thickness of 2 to 4 mm. After production, it is packaged one by one and then assembled for transportation and storage. The existing watch cover packaging machine can only package one by one, which is not only inefficient but also prone to errors and jams, which is not conducive to efficient production. Summary of the invention

[0003] The purpose of the present invention is to provide a splitting mechanism on a cover packaging machine in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the present invention is how to complete the separate packaging of multiple cover sheets at one time.

[0004] The object of the present invention can be achieved by the following technical solutions: A splitting mechanism on a cover packaging machine, characterized in that it includes a carrier plate, a heat-sealing template fixed on the lower surface of the carrier plate and a knife seat, the knife seat has a plurality of transverse blades and a plurality of vertical blades, the transverse blades are perpendicular to the vertical blades, each transverse blade and vertical blade forms a grid with a plurality of molded holes, a support block is slidably connected in the molded hole, and a return spring is connected between the support block and the knife seat at the bottom of the molded hole; in the natural state of the return spring, the support block partially extends out of the molded hole;

[0005] The heat sealing template is provided with a transverse heating strip corresponding to the transverse blade and a vertical heating strip corresponding to the vertical blade;

[0006] The knife seat is provided with breathing holes corresponding to various types of holes, and the breathing hole is in a cone shape with an upper diameter smaller than a lower diameter. A rubber sealing ball is built into the breathing hole. A base plate is fixedly arranged below the knife seat, and exhaust holes corresponding to the breathing holes are provided on the base plate. The support block is provided with an air intake hole, and the air intake hole passes through the upper and lower surfaces of the support block; the exhaust hole is located at an eccentric position of the breathing hole.

[0007] During the downward movement of the support block, the volume of the mold hole decreases and the air pressure increases. Since the exhaust hole is located at the eccentric position of the breathing hole, the gas in the mold hole can be discharged through the exhaust hole. After the heat-sealing template releases the squeeze on the support block, the reset spring resets to increase the volume of the mold hole and form a negative pressure, so that the negative pressure in the suction hole can suck a single packaging bag. On the one hand, it can prevent the cut packaging bags from being misplaced due to the longitudinal movement of the support block, ensuring that the material-retrieving robot can accurately absorb and take away each packaging bag. On the other hand, it can prevent the packaging bag from being stuck in the notch on the heat-sealing template, which is surrounded by the horizontal heating strip and the vertical heating strip.

[0008] Since the blades of the transverse blade and the vertical blade are narrower, and the widths of the transverse heating strip and the vertical heating strip are larger, when the transverse blade and the vertical blade are cutting, it can be ensured that each packaging bag after cutting is in a sealed state with a cover.

[0018] The heat sealing structure includes a fourth cylinder 31, the cylinder body of the fourth cylinder 31 is fixed on the frame, a fifth cylinder 32 is arranged on the push rod of the fourth cylinder 31, the push rod of the fifth cylinder 32 is perpendicular to the push rod of the fourth cylinder 31, a carrier plate 33 is fixed on the push rod of the fifth cylinder 32, the cylinder body of the fifth cylinder 32 is fixed on the push rod of the fourth cylinder 31, and a heat sealing template 34 is arranged on the lower surface of the carrier plate 33;

[0019] The cutting structure includes a knife seat 35 fixed on the frame, and the knife seat 35 has a plurality of transverse blades 36 and a plurality of vertical blades 37. The transverse blades 36 are perpendicular to the vertical blades 37. The transverse blades 36 and the vertical blades 37 form a grid with a plurality of holes. A support block 38 is slidably connected in the hole. A return spring 39 is connected between the support block 38 and the knife seat 35 at the bottom of the hole. When the return spring 39 is in a natural state, the support block 38 partially extends out of the hole.

[0020] The heat sealing template 34 has a transverse heating strip 41 corresponding to the transverse blade 36 and a vertical heating strip 42 corresponding to the vertical blade 37;

[0021] A set of suction cups 5 are respectively provided on both sides of the knife seat 35, and both sets of suction cups 5 are located at the packaging film pulling channel;

[0022] A cutting knife 61 is provided between the film placing roller 1 and the heat sealing mechanism. The cutting knife 61 is fixed on a push rod of a sixth cylinder 62, and the cylinder body of the sixth cylinder 62 is fixed on the frame.

[0023] like Figure 4 and Figure 5 As shown, the knife seat 35 is provided with breathing holes 43 corresponding to the various types of holes, the breathing hole 43 is in a cone shape with an upper diameter smaller than a lower diameter, and a rubber sealing ball 44 is built in the breathing hole 43. A base plate 45 is fixedly arranged below the knife seat 35, and an exhaust hole 46 corresponding to the breathing hole 43 is provided on the base plate 45. An air intake hole 47 is provided on the support block 38, and the air intake hole 47 passes through the upper and lower surfaces of the support block 38; the exhaust hole 46 is located at an eccentric position of the breathing hole 43.

[0024] The packaging method is as follows:

[0025] In the initial state, the broken end of the packaging film is attracted by the suction cup 5 close to the film-releasing roller 1 and positioned, and the two traction manipulators respectively pull out the packaging film by clamping the two sides of the end of the packaging film, so that the end of the packaging film is attracted by the suction cup 5 away from the film-releasing roller 1, and the cutting knife 61 is controlled to cut the packaging film to form a bottom film located above each support block 38;

[0026] A plurality of surface covers to be packaged corresponding to each support block 38 are placed on the bottom film by a material taking robot;

[0027] The two traction manipulators clamp the end of the packaging film again, so that the packaging film covers the top of the surface cover to be packaged to form a mask;

[0028] Without cutting the mask, the heat-sealing template 34 of the heat-sealing structure is controlled to move to above the cover to be packaged, and then the heat-sealing template 34 is controlled to move downward and press each support block 38. In the process of the heat-sealing template 34 pressing the support block 38, each transverse heating strip 41 and the vertical heating strip 42 first heat-bonds the bottom film and the mask to form a grid that separates each cover. After that, each transverse blade 36 and the vertical blade 37 cuts from the middle of the hot melt strip to form a plurality of rectangular packaging bags each individually wrapped with a cover.

[0029] The material-retrieving robot moves again to take away the packaged cover, and then reloads the material, repeating this process to achieve efficient packaging.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
