Description

Technical Field

[0001] This utility model belongs to the field of packaging box production technology, and in particular relates to an automatic packaging box folding machine. Background Technology

[0002] Packaging boxes are commonly used in industrial production. With the development of industrial technology, more and more products need to be packaged in packaging boxes. During the production of packaging boxes, folding machines are usually used to fold the packaging boxes.

[0003] Existing automatic box folding machines typically require applying glue to the side panels of the box during folding for adhesion. However, this manual process involves workers using a brush to apply the glue, which can lead to uneven application and affect the adhesion. Furthermore, manual application to multiple areas is inefficient. Therefore, we have proposed an automatic box folding machine. Utility Model Content

[0004] The purpose of this invention is to provide an automatic packaging box folding machine. By setting up an adhesive application component, specifically, before folding, the electric push rod two is activated to drive the connecting frame downward. At this time, multiple glue storage cylinders move downward simultaneously. When the protrusion contacts the top of the side cardboard, it is pushed upward. At this time, the conical sealing plug opens the bottom of the glue storage cylinder, and the glue leaks from the bottom of the glue storage cylinder and flows onto the side cardboard. This method can apply glue to multiple positions at the same time, eliminating the need for manual application of glue to multiple positions sequentially, greatly improving work efficiency. It solves the problem that existing paper box folding machines require workers to use a brush to apply glue before folding, which can easily lead to uneven glue application, affecting the adhesion effect, and the inefficiency of manual application of glue to multiple positions sequentially.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an automatic folding machine for packaging boxes, comprising a worktable, a top base fixedly connected to the top of the worktable, an adhesive applicator assembly disposed below the top base, and two electric push rods fixedly connected to the top of the top base respectively, with the electric push rod two positioned to the left of the electric push rod one. A square positioning frame is disposed at the center of the bottom of the top base. The adhesive applicator assembly includes four adhesive storage cylinders distributed at the four corners of the square positioning frame, with connecting frames fixedly connected to the outer sides of the four adhesive storage cylinders. The bottom output end of the electric push rod two is fixedly connected to the top of the connecting frame on the left side. The tops of the two adhesive storage cylinders at the front and the two at the rear are... Each glue cylinder has a fixedly connected delivery pipe at its top, and each of the two delivery pipes has a fixedly connected hose at its top. The bottom of the glue storage cylinder is open, and a conical sealing plug is in contact with the bottom of the inner wall of the glue storage cylinder. A protrusion is fixedly connected to the bottom of the conical sealing plug, and a connecting rod is fixedly connected to the top of the conical sealing plug. An outer rod is fixedly connected to the top of the inner wall of the glue storage cylinder, and a spring is installed inside the outer rod. When the glue storage cylinder moves downward, it will be pushed upward when the protrusion contacts the top of the side cardboard. At this time, the conical sealing plug opens the bottom of the glue storage cylinder, and the glue leaks out from the bottom of the glue storage cylinder and flows onto the side cardboard. This method can apply glue to multiple locations at the same time.

[0007] Furthermore, the top of the connecting rod passes through the outer rod and extends into the interior; the top of the spring is fixedly connected to the inner wall of the glue storage cylinder; the bottom of the spring is fixedly connected to the top of the connecting rod; the protrusion is located below the glue storage cylinder; and the top and bottom of the conical sealing plug are both conical. After the conical sealing plug moves upward, the connecting rod slides inside the outer rod and compresses the spring. When the glue storage cylinder returns to its upward position, the conical sealing plug can return downward under the elastic action of the spring to seal the glue storage cylinder.

[0008] Furthermore, a bracket is fixedly connected to the inner wall of the square positioning frame, and the top center of the bracket is fixedly connected to the bottom output end of the electric push rod. A baffle is fixedly connected to the bottom of the workbench, and a positioning frame is fixedly connected to the top of the workbench. A cardboard body is set inside the positioning frame. The cardboard body includes a bottom cardboard. Side cardboard 1 is fixedly connected to both the front and back of the bottom cardboard. Side cardboard 2 is fixedly connected to both the left and right sides of the bottom cardboard. Side-connecting cardboard is fixedly connected to both the front and back of the two side cardboard 2s. Cover cardboard is fixedly connected to the side of the two side cardboard 2s that are far apart from each other. The positioning frame is used to position the cardboard body. At this time, the bottom cardboard will correspond to the fixed seat, the side cardboard 1 will correspond to the folding plate 1, the side cardboard 2 will correspond to the folding plate 2, and the side-connecting cardboard will correspond to the folding plate 3.

[0009] Furthermore, a square slot is provided at the center of the workbench, and a fixed seat is provided inside the square slot. Folding plates one are provided in front of and behind the fixed seat, folding plates two are provided on the left and right sides of the fixed seat, and folding plates three are provided at the four outer corners of the fixed seat. A driving assembly is provided at the bottom of folding plates one, two, and three. Folding plate three is used to fold the side-joining cardboard, folding plate two is used to fold the side cardboard two, and folding plate one is used to fold the side cardboard one.

[0010] Furthermore, connecting blocks are fixedly connected to the bottom of each of the three folding plates, and support frames are fixedly connected to the four corners of the bottom of the fixed base. The other end of the support frame is fixedly connected to the bottom of the workbench. The support frame is used to support the fixed base, and the connecting blocks are used to connect with the support rod, thereby supporting the three folding plates respectively.

[0011] Furthermore, the driving assembly includes a fixed block fixedly connected to the inner wall of the square groove. The fixed block is inclined. An electric push rod three is fixedly connected to the bottom of the fixed block. A push rod is fixedly connected to the top output end of the electric push rod three. A ball-head push block is fixedly connected to the top of the push rod. Support rods are rotatably connected to both ends of the connecting block. The side of the support rod away from the connecting block is fixedly connected to the inner wall of the square groove. The ball-head push block can slide on its surface after pushing the folding plate, thereby pushing the folding plate more smoothly.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting up a glue application component, specifically, before folding, first activates the electric push rod two to drive the connecting frame to move downwards. At this time, multiple glue storage cylinders move downwards simultaneously. When the protrusion contacts the top of the side cardboard one, it will be pushed upwards. At this time, the conical sealing plug opens the bottom of the glue storage cylinder, and the glue leaks from the bottom of the glue storage cylinder and flows onto the side cardboard one. This method can apply glue to multiple positions at the same time, eliminating the need for manual application of glue to multiple positions sequentially, and greatly improving work efficiency.

[0014] 2. This utility model uses three folding plates: folding plate one, folding plate two, and folding plate three. Specifically, folding plate three is used to fold the side-joining cardboard, folding plate two is used to fold the side cardboard two, and folding plate one is used to fold the side cardboard one. This method enables quick folding. At the same time, during the folding process, the square positioning frame can play a role in positioning and limiting, preventing the side cardboard one and side cardboard two from obstructing the area too much, making the cardboard box more square after folding and achieving a better folding effect.

A connecting frame 122 is fixedly connected to the outside of the four glue storage cylinders 121. The bottom output end of the electric push rod 2 112 is fixedly connected to the top of the connecting frame 122 on the left. The tops of the two front glue storage cylinders 121 and the two rear glue storage cylinders 121 are all fixedly connected to conveying pipes 123. The tops of the two conveying pipes 123 are all fixedly connected to... The device includes a flexible hose 124 and a glue storage cylinder 121 with an open bottom. A conical sealing plug 211 is attached to the bottom of the inner wall of the glue storage cylinder 121. A protrusion 212 is fixedly connected to the bottom of the conical sealing plug 211, and a connecting rod 213 is fixedly connected to the top of the conical sealing plug 211. An outer rod 214 is fixedly connected to the top of the inner wall of the glue storage cylinder 121, and a spring 215 is installed inside the outer rod 214. When the electric push rod 112 is activated, the connecting frame 122 moves downward. At this time, multiple glue storage cylinders 121 move downward simultaneously. When the protrusion 212 contacts the top of the side cardboard 132, it is pushed upward. At this time, the conical sealing plug 211 opens the bottom of the glue storage cylinder 121, and the glue leaks out from the bottom of the glue storage cylinder 121 and flows onto the side cardboard 132. This method can apply glue to multiple positions at the same time, eliminating the need for manual application of glue to multiple positions sequentially, and greatly improving work efficiency.

An electric push rod 152 is fixedly connected to the bottom of the fixing block 151. A push rod 153 is fixedly connected to the top output end of the electric push rod 152. A ball head push block 154 is fixedly connected to the top of the push rod 153. Support rods 155 are rotatably connected to both ends of the connecting block 145. The side of the support rod 155 away from the connecting block 145 is fixedly connected to the inner wall of the square groove.

[0033] A specific application of this embodiment is as follows: In use, the hose 124 is first connected to the glue delivery device, and the glue is delivered through the hose 124 to the delivery pipe 123 for diversion, so that the glue enters multiple glue storage cylinders 121 for storage. Then, the cardboard body 13 is placed in the positioning frame 3 on the top of the workbench 1 to position the cardboard body 13. At this time, the bottom cardboard 131 will correspond to the fixed seat 14, the first side cardboard 132 will correspond to the first folding plate 141, the second side cardboard 133 will correspond to the second folding plate 142, and the side connecting cardboard 134 will correspond to the third folding plate 143. Then, the electric push rod 111 is started to drive the square positioning frame 113 downward through the bracket 114, so that the bottom of the square positioning frame 113 contacts the top of the bottom cardboard 131. Then, the electric push rod 111 is started again. Rod 2 112 drives the connecting frame 122 to move downward. At this time, multiple glue storage cylinders 121 move downward simultaneously. The four glue storage cylinders 121 correspond to the two ends of the two side cardboard 132 respectively. When the protrusion 212 contacts the top of the side cardboard 132, it will be pushed upward. At this time, the conical sealing plug 211 opens the bottom of the glue storage cylinder 121, and the connecting rod 213 slides in the outer rod 214 and squeezes the spring 215. At this time, glue leaks from the bottom of the glue storage cylinder 121 and flows onto the side cardboard 132. Then, the electric push rod 2 112 drives the connecting frame 122 to reset upward, and the glue storage cylinder 121 resets upward. The conical sealing plug 211 resets downward under the elastic action of the spring 215 to seal the glue storage cylinder 121. This method can apply glue to multiple positions at the same time.

[0034] After the glue application is complete, first activate the drive assembly 15 at the bottom of folding plate three 143, causing electric push rod three 152 to drive ball head push block 154 upward through push rod 153. Ball head push block 154 then pushes folding plate three 143, and the bottom of folding plate three 143 rotates on support rod 155 through connecting block 145. At this time, folding plate three 143 folds the side joint cardboard 134. Then, activate the drive assembly 15 at the bottom of folding plate two 142 to fold side cardboard two 133 upward. At this time, side cardboard two 133 will contact the outside of square positioning frame 113, and will move the folded side joint cardboard 134 above side cardboard one 132. Then, activate the drive assembly 15 at the bottom of folding plate one 141. Component 15 folds side cardboard 132 upwards. At this time, the glued part of side cardboard 132 will contact the outside of the folded side connecting cardboard 134, thus bonding them together. After folding, side cardboard 132 will contact the outside of the square positioning frame 113. At this time, bottom cardboard 131, side cardboard 132, side connecting cardboard 134 and side cardboard 2 133 are folded into a cardboard box. The lid cardboard 135 does not need to be folded, making it easy to put items in later. After folding, drive component 15 to move in the opposite direction to reset folding plate 141, folding plate 2 142 and folding plate 3 143 respectively. Then, the electric push rod 111 drives the square positioning frame 113 to move upwards to reset, so that the folded cardboard box can be taken out.
