Rotary multi-glue pot edge sealing mechanism, edge sealer and glue changing method

Abstract

The application provides a rotary multi-glue-pot edge sealing mechanism, an edge sealing machine and a glue changing method. The rotary multi-glue-pot edge sealing mechanism comprises a base, a forward-and-backward air cylinder, a rotatable turntable, a rotating device, a glue loading air cylinder, a lifting air cylinder and a plurality of glue pots. The forward-and-backward air cylinder drives the rotatable turntable to move close to the glue loading station, and the lifting air cylinder drives the rotatable turntable to move upwards, so that the glue pot used for glue loading is lifted to the glue loading station. In addition, the glue loading air cylinder under the rotatable turntable pushes the glue receiving groove to horizontally extend outwards, so that the glue receiving groove is located at the bottom end of the glue pot in the glue receiving state, preventing the glue in the glue pot from spilling. Through the above structure, the glue pot is separated from the glue loading station, so that the glue pot can be conveniently moved to the glue loading station when glue loading is needed, avoiding the complex structure and the complex glue loading process caused by placing the glue pot and the glue loading station at the same position.

Description

Technical Field

[0001] This invention relates to the field of sheet metal processing equipment technology, specifically to a rotary multi-glue pot edge sealing mechanism and edge sealing machine, as well as a glue changing method. Background Technology

[0002] Edge banding machines are commonly used processing equipment in the panel furniture industry. Their function is to apply adhesive tape to the cut surfaces of panels. After edge banding, the exposed cut surfaces are covered. Edge banding makes the panels more aesthetically pleasing, providing a decorative effect, and also prevents external moisture from penetrating, extending the lifespan of the panels.

[0003] The applicant previously filed an invention patent with publication number CN114683373A, entitled "A Multi-Glue Pot Edge Sealing Machine". This invention uses multiple glue tanks spaced apart on a turntable, each containing a different type of hot melt adhesive. In use, the turntable, driven by a drive device, rotates the glue tank that requires hot melt adhesive to the heating system. The heating system heats the glue tank that has moved to it, and the heated hot melt adhesive flows to the side of the board, thus achieving the gluing process. By using the rotation and switching of multiple glue tanks, the edge sealing requirements of switching between different types of hot melt adhesive can be met on a single edge sealing machine.

[0004] Although the aforementioned multi-pot adhesive sealing machine uses multiple glue tanks containing different types of hot melt adhesive and a rotating turntable to switch between them to meet various coating requirements, there are several drawbacks. Firstly, the glue tanks cannot be moved back and forth during the coating process. This limits the available space for changing glue, making the glue addition process cumbersome. Secondly, during the switching process from coating to the next glue tank, glue drips from the tank outlet. This dripping glue remains on the outer surface of the board during the turntable's rotation, affecting the edge sealing effect. Summary of the Invention

[0005] In view of the deficiencies in the existing technology, the purpose of this invention is to provide a rotary multi-adhesive pan edge banding machine and edge banding machine, as well as an adhesive changing method, which is convenient for adhesive changing and can effectively prevent adhesive leakage.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, this application provides a rotary multi-glue pot mechanism, which includes a base, a forward / backward cylinder, a rotatable turntable, a rotating device, a glue-filling cylinder, a lifting cylinder, and multiple glue-filling pots. The forward / backward cylinder is located at the bottom end of the base and is used to drive the base to move back and forth. The rotatable turntable is rotatably mounted on the top end of the base. The multiple glue-filling pots are spaced apart on the upper surface of the rotatable turntable. The lifting cylinder is vertically fixedly mounted on the base. One end of the piston rod of the lifting cylinder is fixedly connected to the rotating device and is used to drive the rotating device to move up and down. The glue-filling cylinder is horizontally fixedly mounted at the bottom end of the rotatable turntable. One end of the piston rod of the glue-filling cylinder is provided with a glue-receiving groove, which can extend out and cooperate with the glue-filling pots that are rotated above it.

[0008] Furthermore, the glue-applying pot includes a glue-applying pot body and a glue-closing cylinder disposed on the glue-applying pot body. The glue-applying pot body is detachably mounted on the rotatable turntable. The glue-applying pot body includes a funnel-shaped cavity and a discharge port extending vertically downward from the bottom end of the cavity. The discharge port is connected to the inner cavity of the cavity. The glue-closing cylinder is fixedly mounted on the glue-applying pot body. A round tube is fitted and fixedly mounted on the outer surface of the piston rod of the glue-closing cylinder. The round tube is vertically slidably mounted in the discharge port to realize the opening or closing of the discharge port.

[0009] Furthermore, the outer surface of the circular tube is coated with a Teflon coating.

[0010] Furthermore, the glue-applying pot body is detachably and fixedly mounted on the rotatable turntable by a pair of mounting brackets. The pair of mounting brackets extend horizontally outward from the outer edge of the rotatable turntable, and the two sides of the glue-applying pot body are fixedly connected to the pair of mounting brackets by positioning pins and positioning holes.

[0011] Furthermore, handles are provided on both sides of the upper end face of the glue-applying pot body.

[0012] Secondly, this application also provides a rotary multi-glue pot edge banding machine, which includes a rotary multi-glue pot mechanism as described above. The rotary multi-glue pot edge banding machine also includes a frame, a conveyor line for conveying the board material, an edge banding tape feeding and cutting mechanism, a roller pressing mechanism, a trimming mechanism, an edge scraping mechanism, and a polishing mechanism.

[0013] Thirdly, this application also provides a method for changing the adhesive in a rotary multi-adhesive pot, the method comprising:

[0014] S1. The glue-closing cylinder is pressed down, causing the glue-applying pot to stop discharging glue.

[0015] S2. The forward and backward cylinders drive the glue-applying pot to move forward to the glue-receiving station.

[0016] S3. The glue-filling pot moves upward, the glue-filling cylinder moves forward, glue is added into the glue-filling pot, and after the glue is added, it is rotated so that the glue-filling pot at the next position can be filled with glue.

[0017] S4. The glue-filling cylinder retracts, preparing to unload the glue hopper;

[0018] S5. The glue-filling pot moves downward to reset, the forward and backward cylinders retract, and the glue-filling pot replacement ends.

[0019] S6. After the temperature reaches the guide temperature, the glue-closing cylinder retracts, the glue-filling pot opens the channel, and the glue is dispensed.

[0020] The beneficial effects of this invention are as follows: By providing a forward and backward cylinder at the bottom of the rotatable turntable to drive its forward and backward movement, the forward and backward cylinder drives the rotatable turntable to move closer to the glue application station. At the same time, a lifting cylinder drives the rotatable turntable to move upward, causing the glue application pot used for glue application to rise to the glue application station. In addition, the glue application cylinder located under the rotatable turntable pushes the glue receiving groove to extend horizontally outward, so that the glue receiving groove is located at the bottom of the glue application pot in the glue application state, preventing the glue in the glue application pot from leaking out and spilling. Through the above structure, the glue application pot is separated from the glue application station, which allows the glue application pot to be easily moved to the glue application station when glue application is required, avoiding the complex structure and glue application process caused by placing the glue application pot and the glue application station in the same position.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] See appendix Figures 1 to 3 As shown, this embodiment provides a rotary multi-glue pot edge banding machine, which includes a frame, a conveyor line for conveying boards mounted on the frame, an edge banding tape feeding and cutting mechanism, a roller pressing mechanism, a trimming mechanism, an edge scraping mechanism, a polishing mechanism, and a rotary multi-glue pot mechanism.

[0030] The rotary multi-glue pot mechanism is arranged on the frame near the end of the conveyor line where the sheet material is input. It is used to apply glue to the sides of the sheet material entering the conveyor line. Specifically, the rotary multi-glue pot mechanism in this embodiment includes a rotatable turntable, a base, forward and backward cylinders, a rotating device, a glue-filling cylinder, a lifting cylinder, and multiple glue-applying pots.

[0031] A rotatable turntable is rotatably mounted on the top of the machine base and rotates horizontally relative to the machine base. A rotating device is mounted on the machine base and connected to the rotatable turntable to drive its rotation.

[0032] The base is provided at the bottom of the machine base. The lifting cylinder is fixedly installed on one side of the machine base, and the piston rod of the lifting cylinder is fixedly connected to the machine base to drive the machine base to move up and down. The machine base in the lifting and moving state then synchronously drives the rotatable turntable to move up and down.

[0033] The forward and backward cylinder is located at the bottom of the base and is fixedly connected to the base. It is used to drive the base to move back and forth. The base, which is moving back and forth, then synchronously drives the machine base and the rotatable turntable to move back and forth.

[0034] Multiple glue-applying pots are spaced apart on the outer edge of a rotating turntable, and the pots rotate along with the turntable. This allows the multiple glue-applying pots to be sequentially moved to the glue-applying or glue-adding station during the rotation of the turntable.

[0035] The glue-filling cylinder is horizontally fixed at the bottom of the rotatable turntable. One end of the piston rod of the glue-filling cylinder is provided with a glue-receiving groove, which can extend out and cooperate with the glue-filling pot that rotates above it.

[0036] See attached document Figure 2 and 3 As shown, in this embodiment, the glue-applying pot includes a glue-applying pot body and a glue-closing cylinder disposed on the glue-applying pot body. The glue-applying pot body is detachably mounted on a rotatable turntable. The glue-applying pot body includes a funnel-shaped cavity and a discharge port extending vertically downward from the bottom end of the cavity. The discharge port is connected to the inner cavity of the cavity. The glue-closing cylinder is fixedly mounted on the glue-applying pot body. A round tube is fitted and fixedly mounted on the outer surface of the piston rod of the glue-closing cylinder. The round tube is vertically slidably mounted in the discharge port to realize the opening or closing of the discharge port.

[0037] To prevent the round tube from sticking to the glue when it pushes the glue out of the outlet, the outer surface of the round tube is coated with a Teflon coating.

[0038] Continue to refer to the appendix Figures 2 to 4 As shown, to facilitate the replacement of the glue-applying pot body, it is detachably and securely mounted on a rotatable turntable via a pair of mounting brackets. The mounting brackets extend horizontally outward from the outer edge of the turntable, and both sides of the glue-applying pot body are fixedly connected to the mounting brackets via positioning pins and positioning holes. The positioning pins and holes facilitate easy installation and removal of the glue-applying pot body from the mounting brackets. Furthermore, to further facilitate the replacement of the glue-applying pot body, handles are provided on both sides of the upper end face of the pot body.

[0039] See attached document Figure 5 As shown, for ease of understanding, the following describes the glue changing process in the glue-applying pot of the rotary multi-glue pot edge-sealing machine in this embodiment:

[0040] S1. The glue-closing cylinder is pressed down, causing the glue-applying pot to stop discharging glue.

[0041] S2. The forward and backward cylinders drive the glue-applying pot to move forward to the glue-receiving station.

[0042] S3. The glue-filling pot moves upward, the glue-filling cylinder moves forward, glue is added into the glue-filling pot, and after the glue is added, it is rotated so that the glue-filling pot at the next position can be filled with glue.

[0043] S4. The glue-filling cylinder retracts, preparing to unload the glue hopper;

[0044] S5. The glue-filling pot moves downward to reset, the forward and backward cylinders retract, and the glue-filling pot replacement ends.

[0045] S6. After the temperature reaches the guide temperature, the glue-closing cylinder retracts, the glue-filling hopper opens the channel, and the glue is dispensed.

[0046] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention is also intended to include these modifications and variations.
