Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a glue spraying mechanism of a box gluing machine. Background Art

[0002] Folder gluer is a mechanical equipment used for automatic folder gluing, mainly used for folding and gluing cartons or cardboard boxes. Folder gluer is equipped with feeding system, folding system, glue spraying and gluing system, pressing system and discharge system. Through the automated processing process, it can achieve efficient, accurate and stable production of cartons or cardboard boxes, greatly reducing labor costs.

[0003] The glue spraying system of the box gluer supplies glue to the glue spraying mechanism through a pipe, and the glue is coated on the surface of the cardboard by the rubber roller during the rotation process. However, the rubber roller can only be used to coat the glue of one specification of cardboard. When the specification of the cardboard changes, the rubber roller may be too short to completely coat the cardboard, or the rubber roller may be too long to discharge the glue that cannot contact the cardboard and drips downward. When the box gluer adjusts the processing specifications of the cardboard, the rubber roller cannot be adjusted conveniently. Therefore, we propose a glue spraying mechanism of the box gluer to solve the existing problems. Utility Model Content

[0006] Preferably, the lower end of the telescopic end of the second hydraulic rod is connected to the upper end of the travel plate. When the second hydraulic rod is in operation, the telescopic end is driven to drive the inclined plate to move longitudinally.

[0007] Preferably, a bearing bracket is provided at the lower end of the travel plate, and one end of the second mounting tube is rotatably plugged into the bearing bracket. One end of the rubber roller connected to the second mounting tube is rotatably supported under the travel plate through the rotation support of the bearing bracket.

[0008] Preferably, both ends of the plug tube are provided with hoses, and the hoses are connected with the glue delivery tube. The hot melt adhesive delivered by the glue delivery tube passes through the airflow of the hoses and then converges and is delivered to the inside of the hose.

[0009] Preferably, a plug hole is provided inside the piston and is connected to the plug tube, and the piston is slidably mounted inside the rubber roller. The hot melt adhesive transported through the plug tube enters the piston and is output through the plug hole.

[0010] Preferably, the outer wall of the motor is sleeved with a machine base, the upper end of the machine base is connected to the lower end of the travel plate, and the gear and the gear ring are meshed with each other. The machine base is fixed to the lower end of the travel plate to mount the motor.

[0011] Preferably, the two plug tubes penetrate the mounting tube 1 and the mounting tube 2 respectively, the upper ends of the plug tubes are provided with connecting blocks, the output end of the hydraulic rod 1 is connected to the corresponding connecting block, and the outer wall of the hydraulic rod is sleeved with a fixing sleeve connected to the side of the lower end of the stroke plate.

[0014] 2. The internal space of the rubber roller is adjusted by relatively distributed pistons. When the pistons move relatively, the internal space of the rubber roller is adjusted. The corresponding glue outlet holes at the relative space of the pistons can discharge hot melt glue, and the glue outlet holes of the rubber roller away from the outside of the relative space of the pistons cannot discharge glue. When the specifications of the cardboard change, the rubber roller can be flexibly adjusted. During the processing of the box gluing machine, the glue spraying system is easy to use.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 4 As shown, the utility model proposes a glue spraying mechanism of a box gluing machine, comprising a mounting bracket 1, a rubber roller 3, a mounting tube 1 4, a mounting tube 2 5, a motor 6, a stroke plate 7 and a plug tube 13. A stroke plate 7 is arranged below the mounting bracket 1, and a rubber roller 3 is arranged below the stroke plate 7. A hydraulic rod 2 10 is arranged inside the mounting bracket 1, and the lower end of the telescopic end of the hydraulic rod 2 10 is connected to the upper end of the stroke plate 7. Mounting tube 1 4 and mounting tube 2 5 are respectively arranged at both ends of the rubber roller 3, a bearing bracket 14 is arranged at the lower end of the stroke plate 7, and one end of the mounting tube 2 5 is rotatably plugged into the bearing bracket 14. Plug tubes 13 are arranged inside both ends of the rubber roller 3, and hoses 9 are arranged at both ends of the plug tube 13. A glue feeding hose 2 is arranged inside the mounting bracket 1, and the hose 9 is connected with the glue feeding hose 2. Glue outlet holes 12 distributed in a ring array are opened inside the rubber roller 3.

[0022] The implementation steps based on Example 1 are as follows: the mounting bracket 1 is installed at the original glue spraying and bonding system of the box gluing machine. When the cardboard is located below the glue roller 3, the hydraulic rod 10 drives the stroke plate 7 to descend, and the glue feeding pipe 2 conveys the hot melt glue through the hose 9 into the inside of the glue roller 3. The glue roller 3 rotates through the bearing bracket 14, and the hot melt glue is conveyed and overflowed through the glue outlet hole 12. When the glue coating roller 3 rotates, the hot melt glue on the outer wall is coated on the cardboard, and the glue spraying mechanism of the box gluing machine realizes the gluing processing of the cardboard.

[0023] like Figure 1-Figure 4As shown, compared with the first embodiment, the glue spraying mechanism of the box gluer proposed by the utility model further includes: a piston 18 is provided at the opposite end of the plug tube 13, a plug hole 19 is opened inside the piston 18 and penetrates the plug tube 13, the piston 18 is slidably installed inside the rubber roller 3, a motor 6 is provided at the lower end of the stroke plate 7, the outer wall of the motor 6 is sleeved with the machine base, the upper end of the machine base is connected to the lower end of the stroke plate 7, a gear 15 is provided at the output end of the motor 6, a gear ring 16 is sleeved on the outer wall of the mounting tube, the gear 15 and the gear ring 16 are meshed with each other, hydraulic rods 18 are provided on both sides below the stroke plate 7, two plug tubes 13 respectively penetrate the mounting tube 1 4 and the mounting tube 2 5, and connecting blocks 17 are provided on the upper ends of the plug tubes 13, the output end of the hydraulic rod 18 is connected to the corresponding connecting block 17, and the outer wall of the hydraulic rod is sleeved with a fixing sleeve 11 connected to the side of the lower end of the stroke plate 7.

[0024] In this embodiment, the motor 6 drives the gear 15 to rotate, drives the gear ring 16 to rotate, thereby driving the rubber roller 3 to rotate, and the support is placed on the support plate. The rubber roller 3 can rotate on its own and apply glue to the upper end of the cardboard. The hydraulic rod drives the two connecting blocks 17 to move relative to or away from each other synchronously with the same stroke, thereby driving the plug tube 13 and the piston 18 to move synchronously. Because the hot melt adhesive is output through the plug hole 19 inside the piston 18, during the extrusion process, the hot melt adhesive is located inside the rubber roller 3, and the glue outlet hole 12 at the opposite end of the piston 18 has no hot melt adhesive flowing out. When the specifications of the cardboard change, the position of the piston 18 is adjusted, and then the glue output of the rubber roller 3 is adjusted, thereby avoiding the problem of cumbersome replacement of the glue roller 3 when the box gluing machine adjusts the processing specifications of the cardboard. The use of the rubber roller 3 is flexible and convenient.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
