Description

Technical Field

[0001] The present application relates to the field of knife plate molds, and in particular to a high-speed cotton sticking method and a high-speed cotton sticking machine with a heating mechanism for implementing the method. Background Art

[0002] The flat die cutter is a very commonly used tool in the packaging industry. A blade is provided on the flat die cutter, and the blade is used to cut or indent the packaging material to meet the needs of use.

[0003] Usually, elastic materials are provided on the cutting plates on both sides of the blade of the blade. The elastic materials are foams. The elastic materials are attached to the cutting plates and are located on both sides of the blade, so that the blade is covered in the elastic materials. Only when the elastic materials are compressed during cutting, the blade is exposed. This arrangement can protect the blade and minimize the damage caused by the blade being hit during non-working hours. Secondly, after the blade cuts the packaging material, the compressed elastic materials are reset to lift the packaging material, so that the packaging material is separated from the blade.

[0004] The elastic material can be foam. The foam pasting machine is a machine that realizes automatic pasting of the foam onto the flat die.

[0005] Conventional foam usually has a glue layer at the bottom, and the glue layer is pasted on oil paper, and then the foam is cut into long strips of suitable length as needed. Such long strips of foam are often attached with oil paper, and the oil paper needs to be removed before pasting the long strips of foam to the flat die. In the prior art, the step of removing the oil paper is inefficient on automated equipment, and the quality of removal is not stable.

[0006] If the bottom of the long foam strip is set as hot melt adhesive, the hot melt adhesive is heated and melted when it needs to be pasted to make it sticky, so that oil paper can be eliminated, thereby improving the efficiency and stability of automated operations.

The production method and arrangement of the long strip foam are not limited, and it can be produced in any way, and it can also be arranged and placed on the long strip foam placement station of the high-speed foam applicator as needed.

[0042] like Figures 1 to 4 As shown, an embodiment of the present application provides a high-speed cotton sticking method, which includes the following steps:

[0043] The hot melt adhesive 11 at the bottom of the long foam strip 1 is heated to make the hot melt adhesive 11 sticky;

[0044] Paste the long strip of foam 1 to the preset position of the flat die.

[0045] The long strip of foam 1 is cut into a preset length by a cutting mechanism 2;

[0046] The cut long foam strips 1 are placed on the heating mechanism 4 by the gripper tool head 3 for heating, so that the bottom surface of the hot melt adhesive 11 at the bottom of the long foam strips 1 is melted and becomes sticky;

[0047] The gripper tool head 3 sticks the sticky long strip of foam 1 to the preset position of the flat die.

[0048] The gripper tool head 3 is a technology for which the applicant has previously applied for a patent, and will not be described in detail in this application.

[0049] In this embodiment, Figure 5 As shown, the bottom of the long foam strip 1 is provided with hot melt adhesive 11, which is solid at room temperature and has no viscosity, but becomes viscous when heated to melt. Therefore, the long foam strip 1 does not need to be pasted on the oil paper when not in use, which reduces the use of oil paper and simplifies the automation process of pasting foam, making it more reasonable and stable, and improving work efficiency.

[0050] A high-speed cotton pasting machine with a heating mechanism 4, comprising:

[0051] A work surface 5, on which a flat die placement station 51 is provided;

[0052] An X / Y / Z three-axis feeding mechanism 52, the X / Y / Z three-axis feeding mechanism 52 is disposed above the work surface 5;

[0053] A heating mechanism 4, used for heating the hot melt adhesive 11 at the bottom of the long strip foam 1, the heating device is arranged on one side of the work surface 5;

[0054] The gripper tool head 3 is arranged on the X / Y / Z three-axis feeding mechanism 52 and is used to grab the long strip foam 1 from the heating mechanism 4 to the flat plate die placement 51 station.

[0055] The heating mechanism 4 comprises a heater 41 , on which a heating plate 42 for heating the hot melt adhesive 11 at the bottom of the long strip foam 1 is disposed.

[0056] It also includes a positioning clamp 6 , which is disposed at the front end of the heater 41 . The positioning clamp 6 includes a bottom plate 61 , on which a first clamp 62 and a second clamp 63 are provided to clamp the long strip of foam 1 .

[0057] The facing side surfaces of the first clamp 62 and the second clamp are in the shape of long strips, so as to increase the contact area with the long strip foam 1 and generate a greater clamping force.

[0058] It also includes a cutting mechanism 2, which is used to cut the long strip foam 1 according to a set length. The cutting mechanism 2 is arranged at the front end of the positioning clamp.

[0059] During the cutting operation, one end of the long strip of foam 1 is placed on the bottom plate 61, the first clamp 62 and the second clamp 63 move toward each other to clamp the long strip of foam 1, and the cutting mechanism 2 cuts the long strip of foam 1 according to the set length. The long strip of foam 1 remaining on the bottom plate 61 is required for the next process.

[0060] The cutting mechanism 2 may also be an existing cutting device as long as it can cut the long strips of foam 1 .

[0061] The bottom plate 61 is provided with a first cylinder 64 and a second cylinder 65 facing each other. The output shaft of the first cylinder 64 is fixedly connected to the first clamp 62 , and the cylinder shaft of the second cylinder 65 is fixedly connected to the second clamp 63 .

[0062] When the long foam strip 1 placed on the bottom plate 61 needs to be clamped and fixed, the first cylinder 64 drives the first clamp 62 to move forward, and the second cylinder 64 drives the second clamp 63 to move forward until the long foam strip 1 is clamped and fixed. When the long foam strip 1 needs to be loosened, the cylinder shaft of the first cylinder 62 retracts, the cylinder shaft of the second cylinder 65 retracts, and the first clamp 62 and the second clamp 63 move backward, thereby loosening the long foam strip 1.

[0063] The bottom plate 61 is also provided with a positioning plate 66, and the positioning plate 66 is provided with a plurality of positioning blocks 67. The second clamp 63 is provided with positioning grooves 68 corresponding to the positioning blocks 67, and the positioning blocks 67 are placed in the positioning grooves 68. When the first clamp 62 and the second clamp 63 move toward each other until the long strip of foam 1 is clamped, the positioning blocks 67 are completely located in the positioning grooves 68, and will not hinder the first clamp 62 and the second clamp 63 from clamping the long strip of foam 1.

[0064] The cooperation between the positioning block 67 and the positioning groove 68 can prevent the second clamp 63 from shaking, so that the long strip of foam can be clamped and fixed more reliably and stably with the first clamp 62.

[0065] In this embodiment, the positioning plate 66 is located above the second fixture 63, and the positioning block 67 is located on the lower surface of the second fixture.

[0066] The positioning plate 66 may be disposed below the second fixture 63 , and the positioning block 67 is located on the upper surface of the positioning plate 66 .

[0067] The size and shape of the long foam strip 1 are set according to production needs, and the production method of the long foam strip 1 is selected according to production needs. The long foam strip 1 is arranged as needed and placed on the long foam strip 1 placement station of the high-speed foam laminating machine.

[0068] The first clamp 62 and the second clamp 63 are provided with protruding teeth on the facing sides thereof to enhance the clamping force. In other embodiments, other structures capable of enhancing the clamping force may also be used.

[0069] Specifically, when the high-speed foam pasting machine with a heating mechanism 4 of the present invention is in use, the long strip of foam 1 is conveyed to the bottom plate 61, and in other embodiments, it can also be placed on the bottom plate 61 in other ways; the first clamp 62 and the second clamp 63 move toward each other to clamp the long strip of foam 1, and the cutting mechanism 2 cuts the long strip of foam 1 according to the set length; the first clamp 62 and the second clamp 63 release the long strip of foam 1, the gripper tool head 3 grabs the cut long strip of foam 1 and moves it to the heating plate 42 to heat the hot melt adhesive 11 at the bottom of the long strip of foam 1, and when the heating is completed, the gripper tool head 3 sticks the heated long strip of foam 1 to the flat plate die at the flat plate die placement station 51.

[0070] The present invention is reasonably and cleverly designed. The heating mechanism 4 is provided to heat the hot melt adhesive 11 at the bottom of the long foam strip 1 so that the bottom of the long foam strip 1 becomes sticky, thereby optimizing the process of automatic foam sticking and improving the efficiency and stability of the automatic operation.
