Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a fully automatic packaging production line. Background Art

[0002] Products such as eye patch bags need to be placed in a packaging box after the bag sealing operation to ensure the safety of the products during transportation and improve the grade of the products. Existing eye patch packaging boxes generally consist of an outer box and an inner box support inside. To ensure the support effect of the box support, in the paper box forming equipment, it is generally necessary to stack the cardboard to be folded into a box together, and then label the cardboard in sequence, perform label fitting of the paper box, and then transport it to the forming station for folding the box. However, the existing operations such as paper box labeling and folding rely more on manual work and have a low degree of automation, resulting in low production efficiency. In addition, there is no fully automated production line for the feeding of the existing box support and subsequent box loading, and it cannot meet the requirements of large-volume and rapid packaging.

The distance between the two limiting strips 106 is equal to the length value of the formed box tray. The height position of the upper end of the limiting strip 6 is higher than the height position of the upper surface of the support plate 104.

[0046] The box feeding component is used to send the semi-finished box trays to the front of the conveying component. The end cap forming component is used to fold the end caps inward to form. The support edge forming component is used to fold the support edges downward to form.

[0047] In this embodiment, the cartridge feeding assembly includes a storage hopper 107 and a cartridge feeding rod 108. The storage hopper 107 is located at the upper front end inside the housing 101 and is installed obliquely downward. The semi-finished cartridge trays are placed in the storage hopper 107. The cartridge feeding rod 108 is in the shape of a long rod. One end of the cartridge feeding rod 108 is hinged to the housing 101, and a suction device is installed at the other end. The suction device is used to suck the semi-finished cartridge trays. When the cartridge feeding rod 108 flips upward, it grabs the semi-finished cartridge trays from the storage hopper 107. When the cartridge feeding rod 108 flips downward, it places the grabbed semi-finished cartridge trays between two adjacent positioning plates 103 at the front of the conveying assembly.

[0048] To optimize the product structure, the end cap includes an end portion section and an insertion section. The end portion section is located at the end of the finished cartridge tray. The insertion section is folded and installed on the side of the end portion section away from the finished cartridge tray and is inserted into the finished cartridge tray.

[0049] To facilitate the forming of the end cap, the end cap forming assembly includes a stop bar 109, a folding plate 110, a first cylinder 111, and a second cylinder 112. The two stop bars 109 are respectively installed at intervals outside the two limit bars 106. The end cap is located between the stop bar 109 and the limit bar 106.

The forming device further includes a second lifting seat 116 and a connecting rod 117. The second lifting seat 116 is longitudinally slidably installed between the first lifting seat 113 and the forming seat 114. The number of connecting rods 117 is equal to the number of forming plates 115 and they are installed in one-to-one correspondence. The upper and lower ends of the connecting rod 117 are respectively hinged to the side of the second lifting seat 116 and the upper part of the forming plate 115. At the front, middle, and rear of this conveying assembly, a box feeding assembly, an end cover forming assembly, and a support edge forming assembly are respectively installed. The box feeding assembly is used to convey the semi-finished box to the front of the conveying assembly. When the semi-finished box is conveyed on the conveying assembly, it is extruded and bulged to form. The end cover forming assembly is used to turn the end cover inward to form, and the support edge forming assembly is used to turn the support edge downward to form. The whole process is completely automatically operated by machinery, which improves production efficiency and can ensure the forming quality.

[0051] To ensure the smooth movement of the first lifting seat 113, the forming device further includes a mounting plate 118. The mounting plate 118 is vertically and fixedly installed on the box tray forming machine. One side of the mounting plate 118 is provided with a vertical first guide rail 119. One side of the first lifting seat 113 is slidably installed along the length direction of the first guide rail 119 on the first guide rail 119. The first lifting seat 113 is equipped with a first telescopic rod 120. The first telescopic rod 120 is located above the first lifting seat 113. The fixed end of the first telescopic rod 120 is fixedly installed on the box tray forming machine, and the telescopic end of the first telescopic rod 120 is vertically downward and fixedly connected to the first lifting seat 113.

[0052] To ensure the smooth movement of the forming plate 115, second guide rails 121 are fixedly installed along the length direction on the upper sides of the four sides of the forming seat 114. The upper end of the forming plate 115 is equipped with a square-shaped sliding section, and the sliding section is slidably installed along the length direction of the second guide rail 121 on the second guide rail 121. The forming device further includes a second lifting seat 122 and a connecting rod 117.

The upper and lower ends of the connecting rod 117 are respectively hinged to the side of the second lifting seat 116 and the sliding section of the forming plate 115.

[0053] In order to synchronously translate the four forming plates 115 to ensure the forming quality, a second telescopic rod 123 is installed between the second lifting seat 116 and the forming seat 114. The fixed end of the second telescopic rod 123 is fixedly installed in the middle of the second lifting seat 116, and the telescopic end of the second telescopic rod 123 is vertically downward and fixedly connected to the middle of the forming seat 114. In this embodiment, the first telescopic rod 120 and the second telescopic rod 123 are electric push rods, hydraulic cylinders or air cylinders. A slide rod is installed between the first lifting seat 113 and the forming seat 114. The upper and lower ends of the slide rod are respectively fixedly connected to the first lifting seat 113 and the forming seat 114, and the second lifting seat 116 is slidably sleeved on the slide rod along the length direction of the slide rod. In the present invention, the first telescopic rod 120 drives the first lifting seat 113 and the forming seat 114 to lift and lower, so that the four forming plates 115 below the forming seat 114 move down into the opening in the middle of the upper end surface of the box tray. At this time, the four flanges at the opening of the box tray are turned downwards obliquely, and then the second telescopic rod 123 drives the second lifting seat 116 to move downwards, so that the four forming plates 115 are synchronously translated outwards, and the four flanges at the opening of the box tray are turned to the set position. The whole process is completely automatically operated by machinery, which improves the production efficiency and can ensure the forming quality.

[0054] In order to converge and convey the box trays of the two box tray forming machines, a double-conveyor-line converging structure 2 is also arranged on the frame corresponding to the box tray conveying mechanism and the box tray forming machines. The double-conveyor-line converging structure 2 is used to converge the box trays formed by the two box tray forming machines; specifically, the overall design of the double-conveyor-line converging structure is Y-shaped. The double-conveyor-line converging structure 2 includes two conveyor belts 201. The conveyor belt 201 is divided into an input section and an output section along its conveying direction. Inner baffles 202 and outer baffles 203 are respectively installed on both sides of the conveyor belt 201. The conveying directions of the two conveyor belts 201 are the same. The output sections of the two conveyor belts 201 are adjacent and installed side by side. The inner baffles 202 at the output sections of the two conveyor belts 201 are adjacent and fitted. There is an interval between the tail end of the inner baffle 202 and the tail end of the conveyor belt 201; the double-conveyor-line converging structure also includes two converging plates 204 installed in opposite mirror images. The converging plates 204 are located at the interval between the tail end of the inner baffle 202 and the tail end of the conveyor belt 201. The converging plate 204 includes a guiding section and a converging section integrally formed from front to back. One end of the guiding section is connected to the outer baffle 203 and the other end is smoothly inclined inward. The length direction of the converging section is parallel to the length direction of the output section of the conveyor belt 201. One end of the converging section away from the guiding section is located at the tail end of the conveyor belt 201. The converging sections of the two converging plates 204 are installed at intervals.

[0055] In order to optimize the product structure and ensure the accuracy of the position of the paper box on the conveyor belt 201, the distance values between the inner baffles 202 and the outer baffles 203 of the two conveyor belts 201 are equal, and the distance value between the converging sections of the two converging plates 204 is equal to the distance value between the inner baffle 202 and the outer baffle 203 of any one conveyor belt 201.

[0056] In this embodiment, a sufficient gap is left between the two carton production devices to facilitate operation and maintenance by the staff. The conveyor belt 201 is in a Z shape. The horizontal section and the vertical section of the conveyor belt 201 on the upper side are the input sections, and the horizontal section of the conveyor belt 201 on the lower side is the output section.

[0057] To avoid blockage when the two conveyor belts 201 converge, the double-conveyor-line converging structure further includes two blocking rods 205, which are respectively installed at the front of the output sections of the two conveyor belts 201; the blocking rods 205 have a blocking state and a release state; when the blocking rods 205 are in the blocking state, the blocking rods 205 are horizontally installed above the conveyor belt 201, and the materials on the conveyor belt 201 are blocked by the blocking rods 5; when the blocking rods 205 are in the release state, the blocking rods 205 are away from the conveyor belt 201, and the materials are driven by the conveyor belt 201 to move over the blocking rods 205.

[0058] To further optimize the product structure, the blocking rod 205 is a telescopic rod. The fixed section of the telescopic rod is fixedly installed on the outer baffle 203, and the telescopic section of the telescopic rod extends towards the inner baffle 202.

[0059] The present invention is equipped with two conveyor belts 201. The box outlets of the two carton production devices respectively correspond to the input sections of the two conveyor belts 201. The output sections of the two conveyor belts 201 are installed adjacent and side by side. The materials on the two conveyor belts 201 are converged and the output position is defined through the converging plate 204, which is convenient for docking with the inlet of the automatic cartoning device. There is no need for manual operation, which is conducive to the formation of automated production of the production line.

[0060] Among them, the tray transported through the double-conveyor-line converging structure is transported to the tray conveying mechanism. Pressing rods are installed on the conveying surface of the tray conveying mechanism. The pushing mechanism 6 includes a box blocking plate 601 installed at the end of the tray conveying mechanism. A circulating baffle 602 is rotatably installed on the frame at the position corresponding to the box blocking plate. A circulating pushing conveyor 603 is installed on the frame at the position corresponding to the tray conveying mechanism. The circulating pushing conveyor is arranged perpendicular to the conveying direction of the tray conveying mechanism. A plurality of circulating pushing plates are evenly installed on the conveying surface of the circulating pushing conveyor along the circumferential direction. The circulating pushing conveyor is used to drive the circulating baffle 602 to reciprocate, so as to push the trays in the tray conveying mechanism onto the material leveling conveyor belt, and then load eye patches subsequently. Among them, the automatic cartoning machine uses existing mature equipment. This solution can realize the full-process production of automatic folding, filling, and cartoning of the specific inner trays of eye patch packaging boxes, improving the production and packaging efficiency.

[0061] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
