Description

Technical Field

[0001] This utility model relates to the field of double-sided gluing of sheet materials, and more specifically, to a double-sided gluing device for sheet materials. Background Technology

[0002] In the processing of wooden furniture, thin boards are often coated with glue and then glued together to increase their thickness and strength. Applying glue to the boards requires glue application equipment, and a single-sided glue application method is generally used. This method requires applying glue to the boards twice, which is inefficient. Compared with single-sided glue application, double-sided glue rollers can complete the coating of both the top and bottom surfaces of the board in one go, which is more efficient.

[0003] However, existing double-sided roller coating devices generally have the following problems: during the roller coating process, the glue easily seeps out axially from both sides of the roller coating cylinder. This seeping glue will seep into the bearing of the equipment, and after solidification, it will affect the normal operation of the bearing. It will also drip onto the ground, which not only wastes glue and increases production costs, but also makes cleaning difficult after solidification, pollutes the equipment environment, and affects the normal operation of the equipment. How to invent a double-sided roller coating device for sheet materials to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a double-sided roller coating device for sheet materials, which aims to improve the problem that during the roller coating process, the glue easily seeps out axially from both sides of the roller coating cylinder. This seeping glue will seep into the bearing of the equipment, and after solidification, it will affect the normal operation of the bearing. It will also drip onto the ground, which not only wastes glue and increases production costs, but also makes it difficult to clean after solidification, pollutes the equipment environment, and affects the normal operation of the equipment.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a double-sided gluing device for sheet metal, including a base plate and two sets of guide rollers mounted on the base plate. A mounting frame is provided on the top of the base plate. Two sets of rotating shafts are connected to the inner wall of the mounting frame via bearings. A gear set is provided on the side wall of the mounting frame, driving the two sets of rotating shafts to rotate. A gluing cylinder is sleeved on the outer wall of each set of rotating shafts. Two sets of glue spraying devices are provided on the side wall of the mounting frame, each cooperating with one of the two sets of gluing cylinders. Two sets of flow guide seats are sleeved on the outer wall of each set of rotating shafts, with the side wall of the flow guide seat connected to the side wall of the gluing cylinder. Multiple flow guide strips are provided on the outer wall of the flow guide seat, capable of guiding the glue flow. Two sets of flow gathering grooves are formed on the outer wall of each set of rotating shafts, with the flow guide strips cooperating with the flow gathering grooves.

[0007] Preferably, the outer wall of the rotating shaft has multiple sets of guide grooves, which cooperate with the guide strips and are connected to the flow-gathering grooves.

[0008] Preferably, the guide channel is arranged in the shape of a right trapezoid, and the inclined surface of the guide channel matches the interior of the flow-gathering channel.

[0009] Preferably, the flow-gathering channel is arranged in an annular shape, and a baffle is sleeved on the outer wall of the rotating shaft, with one side wall of the baffle and one inner wall of the flow-gathering channel on the same horizontal plane.

[0010] Preferably, the flow guide seat is shaped like a frustum, and the inclined surface of the flow guide seat cooperates with the guide groove.

[0011] Preferably, the inner wall of the mounting frame is detachably provided with four sets of collection boxes, the collection boxes are located below the flow collection channel, and the bottom of the mounting frame is slidably connected with a receiving tray.

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

[0013] This invention utilizes an innovative combination of a frustum-shaped guide seat, guide strips, a right-angled trapezoidal guide groove, and a flow-gathering groove. This design actively captures most of the glue seeping from both sides of the glue roller, preventing it from seeping into the bearings via the rotating shaft, thus ensuring the normal operation of the device. The flow-gathering groove and baffles guide the glue into a collection box for recycling and reuse. This solves the problem of glue leakage polluting the inside of the equipment and the ground, keeping the equipment clean for extended periods, reducing frequent cleaning work, and saving production costs.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example, refer to Figures 1-4 A double-sided gluing device for sheet metal includes a base plate 1 and two sets of guide rollers 2 mounted on the base plate 1. A mounting frame 5 is located on the top of the base plate 1. Two sets of rotating shafts 8 are connected to the inner wall of the mounting frame 5 via bearings. A gear set 6 (composed of a motor, a driven gear, and a meshing drive gear) is located on the side wall of the mounting frame 5. The two sets of rotating shafts 8 are respectively connected to the side walls of the driven gear and the drive gear (this is prior art). The gear set 6 drives the two sets of rotating shafts 8 to rotate. A gluing cylinder 7 is sleeved on the outer wall of each set of rotating shafts 8. Two sets of glue spraying devices 3 are located on the side wall of the mounting frame 5. Each set of glue spraying devices 3 is paired with two sets of glue rolling cylinders 7. The nozzles of the two sets of glue spraying devices 3 are respectively aligned with the surfaces of the upper and lower sets of glue rolling cylinders 7 to supply glue to them. Two sets of flow guide seats 9 are sleeved on the outer walls of the two sets of rotating shafts 8. The side walls of the flow guide seats 9 are connected to the side walls of the glue rolling cylinders 7. The flow guide seats 9 are set in the shape of a frustum. The inclined surface of the flow guide seats 9 is paired with the guide groove 11. Multiple sets of flow guide strips 10 are provided on the outer walls of the flow guide seats 9. The flow guide strips 10 can guide the glue. Two sets of flow gathering grooves 12 are opened on the outer walls of the two sets of rotating shafts 8. The flow guide strips 10 are paired with the flow gathering grooves 12.

[0022] It should be noted that the guide strip 10 can capture and guide the glue seeping out from the side of the glue roller 7.

[0023] Multiple sets of guide grooves 11 are provided on the outer wall of the rotating shaft 8. The guide grooves 11 cooperate with the guide strips 10 and are connected to the flow-gathering grooves 12. The guide grooves 11 are arranged in the shape of right-angled trapezoids, and the inclined surface of the guide grooves 11 cooperates with the interior of the flow-gathering grooves 12.

[0024] It should be noted that the guide groove 11 and the guide strip 10 correspond one-to-one and fit together, and the inner end of the guide groove 11 is connected to the flow-gathering groove 12. This design allows the glue captured by the guide strip 10 to flow seamlessly into the guide groove 11 and eventually into the flow-gathering groove 12. The right-angled trapezoidal shape of the guide groove 11 helps the glue to slide more smoothly into the flow-gathering groove 12 along the inclined surface under the action of centrifugal force.

[0025] The flow-gathering trough 12 is arranged in an annular groove shape, and a baffle 13 is sleeved on the outer wall of the rotating shaft 8. One side wall of the baffle 13 is on the same horizontal plane as one inner wall of the flow-gathering trough 12.

[0026] It should be noted that the baffle 13 and the flow collection channel 12 together form a complete collection cavity, effectively preventing glue from splashing out of the flow collection channel 12 under centrifugal force.

[0027] The inner wall of the mounting frame 5 is detachably equipped with four sets of collection boxes 14, which are located below the flow collection channel 12. The bottom of the mounting frame 5 is slidably connected with a receiving tray 4.

[0028] It should be noted that: the collection box 14 is used to collect the glue dripping from the flow tank 12, and the receiving tray 4 is used to collect small amounts of glue that may splash and waste materials during daily cleaning.

[0029] Working principle: The guide roller group 2 guides the sheet material, which passes between the upper and lower glue-rolling cylinders 7. The motor drives the upper and lower rotating shafts 8 and the glue-rolling cylinders 7 to rotate in opposite directions via the gear group 6. The glue spraying device 3 evenly sprays glue onto the surface of the glue-rolling cylinders 7. The rotating glue-rolling cylinders 7 evenly coat the glue onto the upper and lower surfaces of the passing sheet material. During the coating process, some glue will penetrate to both sides along the axial direction of the glue-rolling cylinders 7. When the glue seeps to the junction of the end face of the glue-rolling cylinder 7 and the guide seat 9, it will be captured by the high-speed rotating guide strip 10. Under the action of centrifugal force, the glue flows outward along the guide strip 10 and... The glue enters the guide groove 11 and flows along the inclined surface of the guide groove 11, eventually flowing into the annular collection groove 12. In the collection groove 12, the glue adheres to the groove wall due to centrifugal force, but cannot fly out due to the obstruction of the groove wall and the sealing effect of the baffle 13. When it accumulates to a certain amount, or when the centrifugal force disappears due to equipment shutdown, the glue drips downwards due to its own weight. The dripping glue falls into the removable collection box 14 below. The operator can periodically remove the collection box 14 to reuse the recovered clean glue. A very small amount of splashed glue or dripping dust can be received and treated by the receiving tray 4 at the bottom.

[0030] It should be noted that the specific model and specifications need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
