Description

Technical Field

[0001] The present application relates to the field of die cutting molds, and in particular to a pin assembly capable of automatically adjusting the distance between pins, including a material taking and placing tool head for the pin assembly and a flat die cutting automatic stripping machine. Background Art

[0002] Flat die is a very common die-cutting tool in the packaging industry. It consists of a base (cutting plate), knife material, indentation material (optional), elastic material, etc. The knife material or indentation material is used to cut or indent the packaging material to meet the needs of use.

[0003] Usually, the elastic material is flatly attached to the cutting plate on both sides of the blade of the cutting material according to the graphic direction of the cutting material and certain rules. The elastic material should be higher than the height of the blade of the cutting material exposed on the surface of the substrate (cutting plate), so that the blade is covered in the elastic material. Only when the elastic material is compressed during die-cutting will the blade be exposed, and the elastic material can quickly return to its original state after the pressure is removed, so as to achieve the purpose of rapid demolding of the packaging material.

[0004] In the past, the pasting and cutting of elastic materials was completed by manual operation, such as cutting, grabbing and attaching the elastic materials to the two sides of the blade on the knife plate. However, this operation method is inefficient, requires a lot of man-hours, has high labor costs, and the quality of manual grabbing and pasting is unstable, and there are often phenomena such as wrong pasting, missing pasting, and crooked pasting. In addition, because the blade of the knife is very sharp, workers are easily cut when pasting elastic materials, which poses a safety hazard.

[0005] In view of this situation, the applicant has developed a special gripper mechanism to achieve mechanized and automated gripping of elastic materials and attaching them to the corresponding position on the die plate. In the actual production and use process, the gripper mechanism has been optimized to develop a material picking and placing tool head with automatic adjustment of the pin. Utility Model Content

[0065] The number of the pins 61 can be one, two or three.

[0066] One of the pins 61 is fixed, and the other pins 61 are movable, so that the distance between the pins 61 can be adjusted. Of course, all the pins 61 can also be fixed.

[0067] The pin assembly 6 also includes a distance adjusting cylinder 63, which is arranged at the bottom of the material taking and placing body 5, and the cylinder shaft of the distance adjusting cylinder 63 is fixedly connected to a movable base, on which at least one pin 61 is arranged, and the movable base is arranged in parallel with the pin base 62.

[0068] The end of the pin 61 is a sharp end 612, and a barb 611 is provided above the sharp end 612 to increase the force of lifting an object. The pin 61 is provided with a depression, and a slope protrudes outward on the lower end wall of the depression, and the slope is the barb 611.

[0069] It also includes a laser sensor 12, which is arranged at the lower end of the material taking and placing body 5. The laser sensor 12 is connected to a laser distance measuring induction line 121, and the end of the laser distance measuring induction line 121 extends to the side of the plug pin 61 of the plug pin assembly 6. The laser distance measuring induction line 121 is used to detect whether there is an object at a fixed position. For example, the end of the laser distance measuring induction line 121 is located on the side of the plug pin 61, and the end of the laser distance measuring induction line 121 is arranged downward. The detection distance of the laser sensor is to the end of the plug pin 61. When the plug pin 61 is inserted with elastic material, the laser sensor 12 can determine that an object is inserted into the plug pin 61.

[0070] Figures 1 to 5 In the embodiment, the number of the pins 61 in the pin assembly 6 is two, and the barbs 611 of the two pins 61 are arranged opposite to each other, so that when inserting the elastic material, a greater friction force can be provided to lift the elastic material firmly and reliably. The end of the laser ranging induction line 121 is located between the two pins 61.

[0071] The pin assembly 6 includes a distance adjusting cylinder 63, which is arranged at the bottom of the material taking and releasing body 5. There are two pins 61, one of which is fixed on the pin base 62, and the other is fixed on the movable base. The movable base and the pin base 62 are arranged in parallel, so that the position of the movable base can be adjusted by the extension and contraction of the cylinder shaft, thereby adjusting the distance between the two pins 61 to adapt to elastic materials of different sizes.

[0072] Figures 6 to 8 In the figure, only the discharge cylinder 7, the material taking and discharging body 5, the stripper plate 11 and the pin assembly 6 are shown, wherein the pin 61 is fixedly arranged, and the number of the pins 61 is 2. Figure 6 It can be seen that the pin assembly 6 is fixed to the bottom of the material taking and placing body 5 by bolts. Further, although the pins 61 are fixed, in other embodiments, the positions of the pins 61 on the fixed base can also be adjusted, and then the assembly can be assembled to the material taking and placing body 5 to achieve the purpose of adjusting the spacing of the pins 61.

[0074] When it is necessary to grab the elastic material below, the pin 61 sets the direction according to the program, and the material picking motor 3 drives the slide 2 to move downward, thereby driving the rotating fixed seat 4 installed on the slide 2 to move, and the material picking and releasing body 5 follows the downward movement, so that the pin 61 is inserted into the elastic material; the pressing cylinder 9 drives the pressing plate 8 to move downward, and the pressing plate 8 presses on other elastic materials that do not need to be grabbed, so as to prevent other elastic materials from moving up later following the grabbed elastic material; the material picking motor 3 drives the slide 2 to move upward, and the pin 61 moves upward together, and the elastic material on the pin 61 also moves upward together. Due to the action of the pressing plate 8, other elastic materials that are not grabbed remain in place.

[0075] When the tool head of the automatic adjustment pin takes and discharges the material and moves to the position where the elastic material needs to be attached to the flat cutting die, the elastic material needs to be put down, the discharge cylinder 7 works, the cylinder shaft of the discharge cylinder 7 extends, and the connecting rod moves downward, so that the stripping plate 11 pushes the elastic material on the pin 61 downward, so that the elastic material is pressed tightly on the cutting die plate.

[0076] The utility model has a reasonable and ingenious structure, optimizes the material pressing structure and the material stripping structure, so that the elastic material can be better grasped and attached to the flat knife die, the attachment quality is stable and reliable, the efficiency is high, the cost is low, and the hidden danger of worker injury is reduced. An adjusting cylinder is provided, so that the spacing between the pins can be adjusted according to the size of the elastic material to be grasped, so that elastic materials of different sizes can be grasped conveniently.

[0077] The utility model also discloses a flat-plate die-cutting automatic strip pasting machine, which comprises the aforementioned automatic adjustment pin taking and placing tool head.

[0078] The above is only a preferred embodiment of the present application and does not constitute any formal limitation to the present application. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present application by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the present application, or modify it into an equivalent embodiment of equivalent changes.
