Description

Technical Field

[0001] The present application relates to the field of knife templates, and in particular to a pin structure for a strip pasting machine and the strip pasting machine. Background Art

[0002] In the packaging industry, flatbed dies are often used to cut or indent packaging materials. A flatbed die features a blade, and elastic material is placed on either side of the blade's edge. The blade is encased in the elastic material, and only becomes visible when the elastic material is compressed during cutting. This design protects the blade and allows the compressed elastic material to return to its original position after the blade cuts the packaging material, lifting the material and separating it from the blade.

[0003] The applicant has developed a stripping machine that cuts elastic materials, automatically grabs them, automatically places them in the set position of the cutting die, and then bonds them to the cutting die plate. After developing and using the stripping machine, the applicant believes that the pin structure design in existing stripping machines is not perfect. As a result, the pin structure does not have sufficient friction in the vertical direction after inserting the elastic material, and the elastic material does not rotate well during axial rotation. As a result, existing stripping machines often require the simultaneous use of at least two pins to ensure that the elastic material can rotate synchronously with the pin rotation. However, when inserting small-sized elastic materials, the distance between the two pins may be greater than the width of the elastic material. The applicant believes it is necessary to improve the pin structure in existing stripping machines so that the insertion of a pin can cause the elastic material to move in the vertical direction and also achieve the same rotation during axial rotation. For large-area elastic materials, two or three pins can also be flexibly selected for simultaneous use.

[0004] A pin structure for a label applying machine and a label applying machine including the pin structure have become a demand. Utility Model Content

[0005] In view of at least one of the above technical problems, the present application provides a pin structure for a labeling machine;

[0006] The present application also provides a label sticking machine.

[0007] The embodiment of the first aspect of the present application provides a pin structure for a labeling machine, which includes a fixed section, a transition section and a plug section, wherein the end of the plug section is configured as a plug tip;

[0008] At least one positioning surface is provided from the plug tip toward the transition section;

[0009] At least one positioning protrusion is provided on the plug-in section, and the lower surface of the positioning protrusion is configured as an inclined surface for easy insertion.

[0010] As a further improvement of the present invention, the fixing section is a cylinder or a square;

[0011] The cross section of the transition section gradually increases from the end toward the top.

[0012] As a further improvement of the present invention, the positioning surface extends from the plug tip to the transition section.

[0013] As a further improvement of the present invention, the positioning surface extends from the plug tip to the top end of the transition section.

[0014] As a further improvement of the present invention, the plug tip is in a cone shape.

[0015] As a further improvement of the present invention, chamfers are provided at the connections between the front and rear surfaces and the left and right side surfaces of the plug tip.

[0016] As a further improvement of the present invention, the front and rear surfaces of the plug-in tip serve as the positioning surfaces, and the positioning surfaces extend from the plug-in tip to the top end of the transition section.

[0017] As a further improvement of the present invention, the front and rear surfaces and the left and right side surfaces of the plug-in tip are all positioning surfaces, and the positioning surfaces extend from the plug-in tip to the top end of the transition section.

[0018] As a further improvement of the present invention, there are two positioning protrusions, and the two positioning protrusions are arranged above the plug tip.

[0019] A label sticking machine comprises the aforementioned pin structure for the label sticking machine.

[0020] The embodiments of the present application have the following technical effects: The present invention has a reasonable and ingenious structure. By setting the positioning surface, the friction between the pin structure and the elastic material during rotation is enhanced, so that when the pin structure rotates, the elastic material can accurately and immediately follow the pin structure to rotate at the same angle, facilitating the accurate implementation of automated production. The setting of the positioning protrusion also increases the friction of the pin structure in the vertical direction. When the pin structure moves up and down, the elastic material can accurately and immediately rise and fall with it. Due to the improvement of the pin structure, a single pin structure can achieve the insertion and removal effect that previously could only be achieved by multiple pins. The number of pins can be flexibly selected according to the size of the elastic material, and small-area elastic materials can be inserted and removed more easily. A single pin can be used to insert and remove small-area elastic materials, while two or three pins can be flexibly used for large-area elastic materials. This saves the pin's movement stroke and movement time, thereby improving work efficiency.

[0027] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0029] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0030] In the embodiments of the present application, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0031] The elastic material can be sponge, rubber, silicone, etc., as long as it can provide sufficient elasticity to meet the needs of use. In this application, the elastic material is sponge, and the raw material is a sponge sheet. According to the shape and size of the blade on the flat knife die, a sponge strip that matches the shape and size of the blade is cut from the sponge sheet using a cutting tool, so that the sponge strip can protect the blade after being attached to the flat knife die.

[0032] like Figures 1 to 4 As shown, this embodiment provides a pin structure for a label applying machine, which includes a fixed section 1, a transition section 2 and a plug-in section 3, and the end of the plug-in section 3 is set as a plug-in tip 31; in this embodiment, the pin structure is integrally formed, and the fixed section 1, the transition section 2 and the plug-in section 3 are arranged in sequence. When in use, the fixed section 1 is fixed to the gripping tool head of the label applying machine, and the plug-in section 3 is used to insert into the elastic material, and the movement of the pin structure realizes the grabbing, conveying and putting down of the elastic material.

[0033] At least one positioning surface 4 is provided from the plug tip 31 toward the transition section 2;

[0034] The inserting section 3 is provided with at least one positioning protrusion 33, the lower surface of which is configured as an inclined surface 331 for easy insertion. The upper surface of the positioning protrusion is a plane 332, which increases the resistance to cotton removal when the inserting tip 31 is vertically inserted into the elastic material.

[0035] In other embodiments, a plurality of positioning protrusions 33 may be provided to enhance the adhesion of the pin structure to the elastic material after insertion.

[0036] The fixing section 1 is cylindrical or square; it can also be other structures that are easy to fix to other devices, such as a semi-cylindrical or diamond-shaped cross-section. By fixing the fixing section 1 to the gripper tool head of the labeling machine, the pin can move with the gripper tool head to achieve horizontal, vertical and axial movement.

[0037] The cross section of the transition section 2 gradually increases from the end to the top. Since the end of the transition section 2 is connected to the plug section 3, the tip of the plug section 3 is tapered. Therefore, the cross section of the transition section 2 is also designed to gradually increase from the end to the top, making it easier for the pin structure to be inserted into the elastic material.

[0038] The positioning surface 4 extends from the plug tip 31 to the transition section 2. The plug tip 31 is inserted into the elastic material, and a narrow and long hole is formed on the elastic material. The positioning surface 4 and the elastic material are in surface-to-surface contact, so that when the pin structure rotates, the positioning surface 4 drives the elastic material to rotate with it, and there will be no relative shaking or sliding, ensuring the accuracy of the position of the elastic material when it is moved by the pin structure, making automated production

[0039] The positioning surface 4 extends from the plug tip 31 to the top of the transition section 2. When the elastic material is thick, the positioning surface 4 located in the transition section 2 can also provide a positioning function for the elastic material to prevent relative shaking and sliding between the elastic material and the pin structure.

[0040] The plug tip 31 is conical in shape. This facilitates forming a narrow, elongated hole in the elastic material. The conical plug tip 31 forms surface-to-surface contact with the narrow, elongated hole. When the pin structure rotates, the front and rear surfaces, or positioning surfaces 4, of the plug tip 31 drive the elastic material to rotate with it, preventing relative shaking or sliding. This ensures the accuracy of the elastic material's position as it is moved by the pin structure. Conventional conical plug tips 31 form a circular hole in the elastic material. When the pin structure rotates, the conical plug tip 31 and the circular hole have weak adhesion, making them prone to relative sliding or shaking, leading to errors in the elastic material's position parameters and affecting the automation of the next process.

[0041] In addition, the plug tip 31 is in a cone shape, and a step is also formed on the top thereof, which also serves to enhance the adhesion between the plug structure and the elastic material.

[0042] The connection points 31 have chamfers 32 at their junctions with the front and rear surfaces and the left and right side surfaces. The chamfers 32 facilitate insertion of the plug tip 31 into the elastic material and prevent the pin structure from being pulled out of the elastic material with chips or burrs from forming on the upper and lower surfaces of the elastic material.

[0043] The front and rear surfaces of the plug tip 31 serve as the positioning surfaces 4, which extend from the plug tip 31 to the top of the transition section 2. Both the front and rear surfaces of the plug tip 31 serve as positioning surfaces 4, so that the elastic material can be driven in real time regardless of whether the pin structure rotates forward or backward.

[0044] In other embodiments, there may be one or three positioning surfaces 4 .

[0045] The front and rear surfaces and the left and right side surfaces of the plug tip 31 are all positioning surfaces 4 , and the positioning surfaces 4 extend from the plug tip 31 to the top end of the transition section 2 .

[0046] There are two positioning protrusions 33, each positioned above the plugging tip 31. When the pin structure is inserted into the elastic material, a narrow, elongated hole is formed, into which the positioning protrusions 33 are located. Due to the elastic reset of the elastic material, the positioning protrusions 33 are stuck in the elastic material. The positioning protrusions 33 also increase the vertical friction of the pin structure, allowing the elastic material to rise and fall with it in real time and accurately as the pin structure moves up and down.

[0047] A label sticking machine includes the pin structure for the label sticking machine described in the present application.

[0048] The present invention has a rational and ingenious structure. The positioning surface 4 enhances the friction between the pin structure and the elastic material during rotation, allowing the elastic material to accurately and instantly rotate with the pin structure at the same angle as the pin structure, facilitating accurate automated production. The positioning protrusion 33 also enhances the vertical friction of the pin structure, allowing the elastic material to accurately and instantly rise and fall with the pin structure as it moves up and down. Due to the improved pin structure, a single pin structure can achieve the insertion and removal effects previously achieved with multiple pins. The number of pins can be flexibly selected based on the size of the elastic material, making it easier to insert and remove small areas of elastic material. A single pin can be used for small areas of elastic material, while two, three, or more pins can be used for large areas of elastic material. This reduces the pin's travel and movement time, improving work efficiency.

[0049] The above description is merely a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any person skilled in the art can, without departing from the scope of the present invention, utilize the methods and technical contents disclosed above to make many possible changes and modifications to the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any equivalent changes made based on the shape, structure, and principle of the present application without departing from the content of the present invention should be included in the scope of protection of the present application.
