Description

TECHNICAL FIELD

[0001] The utility model belongs to the packaging bag processing technical field, specifically a packaging bag pressure imprint device. BACKGROUND

[0002] Packaging bags are containers used for packaging, protecting, storing, transporting, and displaying goods. They are usually made of plastic, paper, metal, cloth, or other synthetic materials and come in various sizes, shapes, and designs to meet the characteristics of different goods and market demands. Packaging bags are essential daily necessities in people's daily lives. During the production process of packaging bags, the packaging bags are usually subjected to pressure imprinting to form the required patterns.

[0003] The existing packaging bag pressure imprinting device cannot fix the packaging bag well during pressure imprinting, which causes the packaging bag to move easily during pressure imprinting, affecting the pressure imprinting effect, and leading to large pressure imprinting position deviation and affecting the processing quality.

[0004] Therefore, the utility model provides a packaging bag pressure imprinting device. UTILITY MODEL CONTENTS

[0005] To make up for the deficiencies of the prior art and solve at least one technical problem raised in the background.

[0006] The utility model solves the technical problems and adopts the technical scheme: a packaging bag pressure imprinting device, comprising a conveying assembly; a pressure imprinting assembly is installed on one side of the conveying assembly; a pressure imprinting block is installed at the bottom of the pressure imprinting assembly; a plurality of supports are fixedly connected to the outer side of the pressure imprinting block; a sliding rod is slidingly connected to the middle part of the support; a spring is fixedly connected to the top of the sliding rod; one end of the spring is fixedly connected to the support; a fixing frame is fixedly connected to the bottom of the sliding rod; the fixing frame is slidingly connected to the pressure imprinting block; during work, the packaging bag is placed on the conveying assembly; after the conveying assembly is started, the packaging bag moves on the conveying assembly and reaches the bottom of the pressure imprinting assembly; the pressure imprinting assembly is started; the pressure imprinting assembly drives the pressure imprinting block to descend; the fixing frame will first contact the packaging bag and press the packaging bag; with the descent of the pressure imprinting block, the sliding rod slides on the support; the spring becomes larger in elasticity; finally, the pressure imprinting block is flush with the fixing frame; after the pressure imprinting block is pressed, the pressure imprinting assembly drives the pressure imprinting block to rise; the spring elasticity returns and drives the support to slide; the initial position of the fixing frame is lower than the bottom of the pressure imprinting block; the fixing frame will press the packaging bag; the pressure imprinting block first separates from the surface of the packaging bag; then the fixing frame separates.

[0007] Preferably, the conveying assembly has two through holes in the middle, and a cylinder is fixedly connected to the bottom of the conveying assembly. A crossbar is fixedly connected to one end of the cylinder, and two protrusions are fixedly connected to the top of the crossbar. The protrusions correspond to the through holes. During operation, when the packaging bag stops below the imprinting assembly, the cylinder is activated, and the cylinder drives the crossbar to move, which in turn drives the protrusions to extend out of the through holes. The protrusions slightly protrude, lifting the packaging bag. When the fixing frame presses down and fixes the packaging bag, it increases the tension of the packaging bag, ensuring the flatness of the imprinting position of the packaging bag and reducing this loosening phenomenon.

[0008] Preferably, one end of the embossing component is connected to an external air pipe, and one side of the embossing component is connected to multiple air holes. During operation, the external air pipe is connected to an air pump to deliver gas. The gas flows out from the air holes and acts on the surface of the packaging bag. Before embossing, the fixing frame fixes the packaging bag, and the airflow carries away the dust and impurities on the surface of the packaging bag, reducing the adhesion of dust and impurities, which would lead to a poor embossing effect. After embossing, the airflow can accelerate the heat dissipation of the embossing part, so as to facilitate the subsequent collection of containers and avoid the packaging bags from sticking together due to overheating of the embossing part.

[0009] Preferably, one end of the air hole is provided with a flared hole, which is connected to the air hole. During operation, the flared hole guides the airflow emitted from the air hole, allowing it to contact the packaging bag over a larger area and play its role.

[0010] Preferably, the top of the protrusion is provided with a silicone layer, which is fixedly connected to the protrusion. During operation, after the protrusion lifts the packaging paper, the fixing frame presses down on the packaging bag. The silicone layer protects the packaging bag and prevents the protrusion from leaving scratches on the packaging bag when the fixing frame presses down.

[0011] Preferably, the bottom of the fixing frame is provided with a protective pad, which is fixedly connected to the fixing frame. During operation, the protective pad covers the edge of the fixing frame to prevent the fixing frame from pressing down and causing indentations on the surface of the packaging bag.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The packaging bag stamping device of this utility model, by setting a fixing frame, fixes the packaging bag and the stamping part before the stamping block stamps. After the stamping is completed, the fixing frame will help the stamping block to detach from the packaging to avoid the stamping block sticking to the packaging bag.

[0014] 2. The packaging bag embossing device of this utility model uses slightly raised protrusions to lift the packaging bag. When the fixing frame presses down on the packaging bag, it increases the tension of the packaging bag, ensuring the flatness of the embossing position and reducing the loosening phenomenon.

Specific implementation

[0022] In order to make the technical means, creation features, reach the purpose and the easy understanding of utility model effect, the following specific implementation, further elaborates the utility model.

[0023] For example Figs. 1 to 5As shown in the embodiment of this utility model, a packaging bag stamping device includes a conveying assembly 1; an stamping assembly 11 is installed on one side of the conveying assembly 1, and an stamping block 12 is installed at the bottom of the stamping assembly 11. Multiple supports 13 are fixedly connected to the outer side of the stamping block 12. A slide rod 14 is slidably connected to the middle of each support 13. A spring 15 is fixedly connected to the top of the slide rod 14, and one end of the spring 15 is fixedly connected to the support 13. A fixing frame 16 is fixedly connected to the bottom of the slide rod 14, and the fixing frame 16 is slidably connected to the stamping block 12. When a packaging bag is placed on the conveying assembly 1 and the conveying assembly 1 is started, the packaging bag is transported on the conveying assembly 1 until it reaches below the stamping assembly 11. The stamping assembly 11 then starts, causing the stamping block 12 to descend and be fixed. The frame 16 will first contact the packaging bag and squeeze and fix it. As the imprinting block 12 descends, the slide bar 14 slides on the support 13, and the spring 15 becomes more elastic. Finally, the imprinting block 12 is flush with the fixed frame 16. After the imprinting block 12 finishes imprinting, the imprinting assembly 11 drives the imprinting block 12 to rise. The spring 15 returns to its elasticity and drives the support 13 to slide. The initial position of the fixed frame 16 is lower than that of the imprinting block 12. The fixed frame 16 will press down on the packaging bag. The imprinting block 12 will first detach from the surface of the packaging bag, and then the fixed frame 16 will detach. By setting the fixed frame 16, the packaging bag is fixed before the imprinting block 12 imprints, and the imprinting part is fixed. After the imprinting is completed, the fixed frame 16 will assist the imprinting block 12 to detach from the packaging, avoiding the imprinting block 12 from sticking to the packaging bag.

[0024] like Figs. 1 to 4 As shown, the conveying component 1 has two through holes 2 in the middle. A cylinder 21 is fixedly connected to the bottom of the conveying component 1. A crossbar 22 is fixedly connected to one end of the cylinder 21. Two protrusions 23 are fixedly connected to the top of the crossbar 22. The protrusions 23 correspond to the through holes 2. When the packaging bag stops below the imprinting component 11, the cylinder 21 is activated. The cylinder 21 drives the crossbar 22 to move, which in turn drives the protrusions 23 to extend out of the through holes 2. The protrusions 23 protrude slightly, lifting the packaging bag. When the fixing frame 16 presses down and fixes the packaging bag, it increases the tension of the packaging bag, ensuring the flatness of the imprinting position of the packaging bag and reducing this loosening phenomenon.

[0025] like Figs. 1 to 4 As shown, one end of the embossing component 11 is connected to an external air pipe 3, and one side of the embossing component 11 is connected to multiple air holes 31. The external air pipe 3 is connected to an air pump to deliver gas. The gas flows out from the air holes 31 and acts on the surface of the packaging bag. Before embossing, the fixing frame 16 fixes the packaging bag. The airflow carries away the dust and impurities on the surface of the packaging bag, reducing the adhesion of dust and impurities, which would lead to a poor embossing effect. After embossing, the airflow can accelerate the heat dissipation of the embossing part, so as to facilitate the subsequent collection of containers and avoid the packaging bags from sticking together due to overheating of the embossing part.

[0026] As Figs. 1 to 4 shown in the figure, the air hole 31 is provided with a flared hole 4 at one end, the flared hole 4 is communicated with the air hole 31, the flared hole 4 guides the air flow discharged from the air hole 31, so that it contacts the packaging bag in a larger area and plays a role.

[0027] As Figs. 1 to 3 shown in the figure, the top of the convex block 23 is provided with a silica gel layer 5, the silica gel layer 5 is fixedly connected with the convex block 23, after the convex block 23 lifts the packaging paper, the fixed frame 16 presses down the packaging bag, the silica gel layer 5 protects the packaging bag, avoiding leaving scratches on the packaging bag when the fixed frame 16 presses down.

[0028] As Figs. 1 to 5 shown in the figure, the bottom of the fixed frame 16 is provided with a protective pad 6, the protective pad 6 is fixedly connected with the fixed frame 16, the protective pad 6 covers the edge of the fixed frame 16, avoiding causing indentation on the surface of the packaging bag when the fixed frame 16 presses down.

[0029] Working principle: the packaging bag is placed on the conveying assembly 1, after the conveying assembly 1 is started, the packaging bag is moved on the conveying assembly 1, reaches below the stamping assembly 11, the stamping assembly 11 is started, the stamping assembly 11 drives the stamping block 12 to descend, the fixed frame 16 will first contact the packaging bag and extrude the fixed packaging bag, along with the descent of the stamping block 12, the slide rod 14 slides on the support 13, the spring 15 is elastically larger, finally the stamping block 12 is flush with the fixed frame 16, after the stamping block 12 is pressed to stamp, the stamping assembly 11 drives the stamping block 12 to ascend, the spring 15 restores the elastic force and will drive the support 13 to slide, the initial position of the fixed frame 16 is lower than the stamping block 12, the fixed frame 16 will press the packaging bag, the stamping block 12 is first separated from the surface of the packaging bag, and then the fixed frame 16 is separated; by arranging the fixed frame 16, the packaging bag is fixed before the stamping block 12 stamps, and the stamping part is fixed, after the stamping is completed, the fixed frame 16 will assist the stamping block 12 to separate from the packaging, so that the stamping block 12 and the packaging bag are not adhered, when the packaging bag stops below the stamping assembly 11, the air cylinder 21 is started, the air cylinder 21 drives the cross rod 22 to move, and then drives the protruding block 23 to extend in the through hole 2, the protruding block 23 is slightly protruding, the packaging bag is lifted, when the fixed frame 16 fixes the packaging bag by pressing downward, the tension of the packaging bag is increased, the flatness of the stamping position of the packaging bag is ensured, the relaxation phenomenon is reduced, the external air pipe 3 is communicated with the air pump to deliver gas, the gas flows out from the air hole 31 and acts on the surface of the packaging bag, before stamping, the fixed frame 16 fixes the packaging bag, the airflow carries away the dust and impurities on the surface of the packaging bag, reduces the attachment of the dust and impurities, causes the stamping effect to be poor, after stamping is completed, the airflow can accelerate the heat dissipation of the stamping part, so that subsequent collection and packaging are facilitated, and the packaging bags are not adhered due to overheating of the stamping part. The expanded hole 4 guides the airflow discharged from the air hole 31 to make the airflow contact the packaging bag in a larger area and play a role, after the protruding block 23 lifts the packaging paper, the fixed frame 16 presses the packaging bag downward, the silica gel layer 5 protects the packaging bag, avoids that the protruding block 23 leaves scratches on the packaging bag when the fixed frame 16 presses downward, and the protection pad 6 covers the edge of the fixed frame 16, so that the fixed frame 16 does not cause pressure marks on the surface of the packaging bag when pressing downward.
