Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a sealing tape feeding device. Background Technology

[0002] With the expansion of customized furniture production capacity, most furniture uses wood panels, which typically require edge banding, necessitating the use of edge banding machines. Current edge banding machines are developing towards "high speed, multi-head, and flexibility," and the edge banding tape feeding device has also been upgraded from a single roll, single channel to a multi-channel online switching system, enabling non-stop tape changing and rapid switching between multiple specifications. Existing technology generally adopts a "horizontally parallel" multi-channel structure: multiple sets of edge banding tape rolls and traction units are horizontally arranged on the same side of the edge banding machine, with the center line of each channel perpendicular to the board feeding direction. While this solution can meet the need for continuous tape supply, it still has drawbacks: each additional channel in the feeding device requires an increase in the width of the entire machine, resulting in a large footprint.

[0003] Therefore, there is an urgent need to develop a sealing tape feeding device. Utility Model Content

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Embodiments of this application provide an edge banding tape feeding device for use with a wood edge banding machine; such as Figure 1-20 As shown, the feeding device includes: a housing 100, a car 200, several pallet assemblies 300, a lifting mechanism 400, a pushing device 600, and a flexible guide device 700; the housing 100 is provided with a guide opening 101; the car 200 can move up and down within the housing 100 along a first direction Z; several pallet assemblies 300 are arranged sequentially within the car 200 along the first direction Z; an edge sealing strip 301 is sleeved inside each pallet assembly 300; the lifting mechanism 400 is used to drive the car 200 to move up and down within the housing 100 along the first direction Z; the lifting mechanism is provided with a counterweight unit, which is used to balance the weight of the car; the pushing device 600 drives the edge sealing strip 301 to be discharged to be conveyed along a second direction Y to the guide opening 101 to the edge sealing machine; the flexible guide device 700 is located outside the guide opening 101, and its purpose is to allow the edge sealing strip 301 to enter the edge sealing machine along the flexible guide device 700.

[0023] Preferably, such as Figure 1As shown, multiple sets of pallet assemblies 300 are provided to enable switching and feeding of multiple sets of edge banding tape 301 of different specifications. Preferably, more than 6 sets of pallet assemblies 300 are provided, such as 12 sets. The 12 sets of pallet assemblies 300 are arranged longitudinally in sequence within the car 200. The 12 sets of pallet assemblies 300 in the car 200 are pulled by the lifting mechanism 400, enabling the replacement of edge banding tape 301 of different specifications in the longitudinal position, thereby improving work efficiency. Furthermore, the housing 100 is provided with a switchable front panel 102. When the edge banding tape 301 is used up, the front panel 102 can be manually opened to replace the pallet assemblies 300, thereby replacing the edge banding tape 301.

[0024] In some implementations, such as Figure 2 As shown, the housing 100 has two guide pillars 103 inside, and the car 200 is fitted onto the guide pillars 103. The lifting mechanism 400 drives the car 200 to move up and down along the guide pillars 103. The lifting mechanism 400 includes a first motor 401, a rotating shaft 402, a belt 403, and a counterweight unit 404. The rotating shaft 402 is fixedly connected to the output shaft of the first motor 401, and the rotating shaft 402 is provided with a driven wheel 4021. The belt 403 is fitted onto the driven wheel 4021, and one end of the belt is fixed to the top of the car 200. The first motor 401 drives the belt 403 to rotate, so that the car 200 moves up and down in the first direction Z inside the housing 100. The other end of the belt 403 is fixed to the counterweight unit 404.

[0025] Preferably, the counterweight unit 404 can be a counterweight block or a linear cylinder. When the counterweight unit 404 is a linear cylinder, the other end of the belt 403 is fixed to the piston rod of the linear cylinder. When the car 200 is lifting, the linear cylinder provides a downward pulling force to the belt 403. Under the combined action of the downward pulling force of the linear cylinder and the drag force provided by the rotation of the first motor 401 to the belt 403, the car is lifted upward, thereby reducing the driving load of the first motor 401. When the car 200 is descending, the first motor 401 rotates in the opposite direction to control the release speed of the belt, providing appropriate resistance for the descent of the car 200 to prevent it from accelerating downward due to gravity. At this time, the linear cylinder still provides a downward pulling force to the belt 403 (that is, an upward pulling force on the car 200), further offsetting part of the weight of the car 200 itself and helping to slow down the descent speed. Through the cooperation of the first motor 401 and the counterweight unit 404, the car 200 can remain stable and controllable during descent; the pulling force of the linear cylinder plays a certain role in buffering and restraining, effectively reducing the risk of the car 200 falling out of control, significantly improving the safety of the device operation, and effectively extending the service life of the device.

[0026] In some implementations, such as Figure 6-7As shown, the pallet assembly 300 includes a main guide rail 303, which is disposed on both sides of the base plate 310. Secondary guide rails 201 are provided at both ends inside the car 200. The secondary guide rails 201 cooperate with the main guide rail 303 to achieve loading and unloading of the pallet assembly 300. One of the main guide rails 303 is provided with a latch 3031, which unlocks the pallet assembly 300 by pressing the latch 3031. Specifically, the main guide rail 303 is provided with a locking hook, and the secondary guide rail 201 is provided with a lock. The secondary guide rail 201 and the main guide rail 303 are locked together by the engagement of the locking hook and the locking groove. When installing the tray assembly 300, pushing the tray assembly 300 engages the locking hook with the locking groove to prevent the tray assembly 300 from coming out. When removing the tray assembly 300, pressing the latch 3031 drives the locking hook to disengage from the locking groove, releasing the engagement and unlocking the tray assembly 300 so that it can be pulled out of the car 200. This is the same working principle as the installation and removal of drawers in the prior art. The secondary guide rail 201 and the main guide rail 303 are obtained from the prior art and are not the technical protection points of this application. Specific details will not be elaborated or shown, but this does not mean that they cannot be implemented.

[0027] In some implementations, such as Figure 8-9 As shown, the pallet assembly 300 further includes a base plate 310, a turntable 302, an expansion mechanism 304, a guide belt 305, a first cylinder 306, and a positioning pin 307. The turntable 302 is mounted on the base plate 310 and is rotatably connected to the base plate 310. The edge sealing strip 301 is in the shape of a circular roll. The expansion mechanism 304 is fixed in the middle of the turntable 302 and located in the inner ring of the edge sealing strip 301. The expansion mechanism 304 is used to tighten the edge sealing strip 301. In actual production, the circular roll edge sealing strip 301 is a finished product and is directly installed on the turntable 302. The guide belt 305 is used to guide the edge sealing strip 301 to the guide belt opening 101. The guide belt 305 is provided with a through hole 3053. The piston rod of the first cylinder 306 is connected to one end of the guide belt 305. The positioning pin 307 is used to further fix the pallet assembly 300.

[0028] In some implementations, such as Figure 8-10 As shown, the expansion mechanism 304 is used to adapt to edge banding tapes 301 with different inner diameters. For example, the inner diameter of the circular roll edge banding tape 301 may be different, some large and some small. To ensure the wide applicability of this device, the expansion mechanism 304 is provided. The expansion mechanism 304 includes: several expansion claws 3041, a rotating wheel 3042 and a fixing member 3043. One end of the several expansion claws 3041 is inserted into the rotating wheel 3042. The rotating wheel 3042 is used to drive the expansion claws 3041 to move, realizing the opening and retraction of the expansion claws 3041. The fixing member 3043 is used to lock the rotating wheel 3042 on the turntable 302.

[0029] Specifically, multiple expansion claws 3041 are provided, preferably six expansion claws 3041. The six expansion claws 3041 are evenly distributed around the central axis of the rotating wheel 3042. One end of each expansion claw 3041 is provided with a rotating pin 30411. The rotating wheel 3042 is provided with a sliding groove 30421 that matches the rotating pin 30411. By manually rotating the rotating wheel 3042, the rotating wheel 3042 drives the rotating pin 30411 to slide in the sliding groove 30421, so that the six expansion claws 3041 extend and retract synchronously. When rotating clockwise, the sealing strip 301 is opened and tightened. When rotating counterclockwise, the expansion claws 3041 are retracted. At this time, the expansion claws 3041 no longer abut against the sealing strip 301, so as to facilitate the removal of the sealing strip 301. Preferably, the fixing member 3043 is a locking screw. After locking, the components of the expansion mechanism 304 are kept in a fixed position. Therefore, the expansion claw 3041 of the expansion mechanism 304, in cooperation with the rotating wheel 3042, can realize the opening and retraction of the expansion claw 3041. That is, the expansion mechanism 304 can abut against the ring-shaped sealing strip 301 with different inner diameters, so as to realize the stepless control of the expansion mechanism 304.

[0030] In some implementations, such as Figure 14-15 As shown, the guide belt 305 is disposed on one side of the guide belt opening 101, and the edge sealing tape 301 is output from the guide belt 305 to the guide belt opening 101. The purpose of the guide belt 305 is to cooperate with the first cylinder 306 to ensure a smooth transition of the edge sealing tape 301 from the pallet assembly 300 to the guide belt opening 101. Specifically, the guide belt 305 is provided with an arc-shaped guide plate 3051 and a first auxiliary wheel 3052, wherein the first auxiliary wheel 3052 abuts against the edge sealing tape 301 to guide the edge sealing tape 301 so that it can be smoothly discharged. One end of the arc-shaped guide plate 3051 is fixedly connected to the piston rod of the first cylinder 306. When the edge sealing tape 301 is first installed on the pallet assembly 300, the edge sealing tape... 301 is in a fully rolled state; at this time, the feeding path of the sealing tape 301 has no bends and the feeding resistance is small; as the sealing machine continues to pull the sealing tape 301, the sealing tape 301 is gradually consumed. Therefore, the diameter of the circular rolled sealing tape 301 gradually decreases, and the moving path of the sealing tape 301 changes. The piston rod of the first cylinder 306 slowly extends, driving the arc-shaped guide plate 3051 to rotate, so that the arc surface of the arc-shaped guide plate 3051 is in real time in contact with the inner surface of the reduced sealing tape 301; during this process, the first auxiliary wheel 3052 also swings synchronously with the arc-shaped guide plate 3051, always abutting the outer surface of the sealing tape 301, ensuring that the material output of the sealing tape 301 is continuous and smooth.

[0031] In some implementations, such as Figure 4-5As shown, a vent pipe 202 is fixed on the car 200. The vent pipe 202 is a hollow pipe, and it is equipped with vent nozzles 2021 that match the tray assembly 300, i.e., 12 vent nozzles 2021. Gas is delivered to the first cylinder 306 through the vent pipe 202. Specifically, the tray assembly 300 is equipped with a rubber air seal 309. Gas is delivered by connecting the vent nozzles 2021 to the rubber air seal 309. A flexible hose (not shown) is provided between the rubber air seal 309 and the first cylinder 306 for gas delivery. When one of the tray assemblies 300 needs to be replaced, the tray assembly 300 is pulled out of the car 200. When a single tray assembly 300 is pulled out, the air source is cut off, and no air is supplied to the air distribution pipe 202 to prevent air leakage after the air distribution nozzle 2021 is detached from the rubber air seal 309; at the same time, no more gas is delivered to the first cylinder 306; when the tray assembly 300 is installed into the car 200 via the secondary guide rail 201, the air distribution nozzle 2021 will be inserted into the rubber air seal 309, thereby realizing the delivery of air; it should be noted that the gas source described in this application is connected to the air pump, which is an external device used to provide the air source. The pressure of the air source is selected according to the requirements. The air pump is obtained directly from the prior art. Therefore, its structure is not specifically described in this application.

[0032] In some implementations, such as Figure 4-5 and Figure 11 As shown, a heating element 308 is also provided below the tray assembly 300, and the output end of the heating element 308 is a contact-type electrical terminal 3081; the car 200 is also fixed with bakelite 203, and the bakelite 203 is provided with at least one copper sheet 2031. Preferably, there are two copper sheets 2031. The copper sheets 2031 abut against the electrical terminal 3081 of the heating element 308 to realize power supply; specifically, when the tray assembly 300 is pushed into the auxiliary guide rail 201, the copper sheet 2031 contacts the electrical terminal 3081 and is energized. When the tray assembly 300 is pulled out, the copper sheet 2031 does not contact the electrical terminal 3081 (disconnects), and the heating element 308 is de-energized.

[0033] In some implementations, such as Figure 3-4As shown, there are two positioning pins 307, which are respectively disposed on both sides of the base plate 310. The feeding device of this application also includes a positioning device 500, which includes a second cylinder 501 and a buckle 502. The second cylinder 501 is disposed inside the housing 100. The second cylinder 501 drives the buckle 502 to rotate, so that the buckle 502 cooperates with the positioning pin 307 to further fix the tray assembly 300. The end of the buckle 502 is provided with a groove. The state in which the buckle 502 cooperates with the positioning pin 307 is such that the positioning pin 307 is embedded in the groove of the buckle 502, thereby preventing the tray assembly 300 from loosening. Specifically, the second cylinder 501 is a rotary cylinder. When it is necessary to replace or disassemble the tray assembly 300, the rotary cylinder drives the buckle 502 to rotate, so that it disengages from the positioning pin 307, thereby allowing the tray assembly 300 to be replaced and disassembled.

[0034] In some implementations, such as Figure 12-18 As shown, the pushing device 600 includes: a drive roller 601, a second motor 602, a third cylinder 603, a first encoder 604, a fourth cylinder 605, and a photoelectric sensor 606. The drive roller 601 is disposed on both sides of the sealing strip 301 to be discharged, and the sealing strip 301 is moved by the drive rollers 601 on both sides. The drive roller 601 is disposed on the output shaft of the second motor 602. The piston rod of the third cylinder 603 is connected to a first mounting plate 6031, and the housing of the second motor 602 is fixed on the first mounting plate 6031. Its purpose is to make the drive roller 601 move in the third direction X by the piston movement of the third cylinder 603. The first encoder 604... 4. The first encoder 604's code disk 6041 abuts against the sealing tape 301, and the piston rod of the fourth cylinder 605 is connected to the second mounting plate 6051. The housing of the fourth cylinder 605 is fixed on the second mounting plate 6051. The purpose is to move the code disk 6041 of the first encoder 604 in the third direction X through the piston movement of the fourth cylinder 605, thereby abutting against the sealing tape 301. The photoelectric sensor 606 is set above the outer side of the guide tape opening 101. Through the cooperation of the photoelectric sensor 606 and the first encoder 604, the displacement distance of the sealing tape 301, that is, the length of the sealing tape 301 sent out or retracted, is measured.

[0035] Specifically, when assembling or replacing the pallet assembly 300, the drive roller 601 and the code disk 6041 of the first encoder 604 do not abut against the edge sealing tape 301, leaving a certain position for the edge sealing tape 301. After the edge banding tape 301 to be discharged is aligned with the guide opening 101, the third cylinders 603 on both sides drive the mounting plate to move the active roller 601 toward the edge banding tape 301. Since the guide component 305 is provided with a through hole 3053, the active roller 601 can abut and clamp the edge banding tape 301. At the same time, the code disk 6041 of the first encoder 604 abuts the edge banding tape 301. After the active roller 601 clamps the edge banding tape 301, the second motor 602 is started to drive the active roller 601 to rotate and drive the edge banding tape 301 to feed along the guide opening 101. When the edge banding tape 301 moves to below the photoelectric sensor 606, the photoelectric sensor 606 triggers a signal. Then the first encoder 604 calculates the length of the edge banding tape 301. When the preset feeding length is reached, the second motor 602 stops rotating, completing the precise positioning of the edge banding tape 301 and waiting for the pulling signal of the edge banding machine.

[0036] In some implementations, such as Figure 13 and Figure 18 As shown, the pushing device 600 also includes a braking mechanism 607, which is disposed inside the housing 100. The braking mechanism 607 includes a third motor 6071, an electromagnetic brake 6072, and a fifth cylinder 6073. The output shaft of the third motor 6071 is fixedly connected to a friction wheel 6074, which abuts against the turntable 302. The electromagnetic brake 6072 is disposed between the friction wheel 6074 and the third motor 6071. The piston rod of the fifth cylinder 6073 is connected to a third mounting plate 60731, and the housing of the third motor 6071 is fixed on the third mounting plate 60731. The purpose is to cause the friction wheel 6074 to move in the third direction X by the piston movement of the fifth cylinder 6073, thereby abutting against the sealing strip 301.

[0037] When the friction wheel 6074 is conveying and retrieving the edge banding tape 301, it remains in contact with the turntable 302. Only when the edge banding tape 301 needs to be replaced will the fifth cylinder 6073 move the friction wheel 6074 away from the turntable 302. Specifically, since the edge banding tape 301 is located on the turntable 302 and is stretched and tightened by the expansion claws 3041 of the expansion mechanism 304, when the edge banding tape 301 is pulled, the turntable 302 rotates with the edge banding tape 301; the friction wheel 6074 abuts against the turntable 302 and rotates with it. During this period, the third motor 6071 does not operate. When changing to a different specification of edge banding tape 301, the friction wheel 6074 does not abut against the turntable 302, reserving a certain position for the edge banding tape 301. When the edge banding tape 301 is being discharged, the edge banding machine pulls the edge banding tape 301 to rotate, and the turntable 302 rotates with the edge banding tape 301.

[0038] Furthermore, the electromagnetic brake 6072 is existing technology. When the edge banding tape 301 does not need to be discharged, the electromagnetic brake 6072 energizes the friction wheel 6074, causing the friction wheel 6074 to stop rotating. Since the friction wheel 6074 abuts against the turntable 302, the turntable 302 also stops rotating, thus preventing the edge banding tape 301 from being fed. When it is necessary to replace the edge banding tape 301 with a different specification, the remaining edge banding tape 301 needs to be recycled. At this time, the electromagnetic brake 6072 first drives the friction wheel 6074 to stop the turntable 302, causing the edge banding tape installed on the turntable 302 to stop. 301 stops feeding; subsequently, the electromagnetic brake 6072 is de-energized, and the third motor 6071 is started. The output shaft of the third motor 6071 drives the friction wheel 6074 to rotate, which in turn drives the turntable 302 to rotate and retract the sealing tape 301. The sealing tape 301 returns to the inside of the housing 100. When the sealing tape 301 has completely passed the photoelectric sensor 606, the photoelectric sensor 606 triggers a signal again, and the encoder starts working. When it returns to the inside of the housing 100, the third motor 6071 stops rotating; the retraction action of the sealing tape 301 is completed.

[0039] In some implementations, such as Figures 19-20 As shown, one end of the flexible guide strip device 700 is fixed to the outside of the guide strip opening 101, and the other end is used in conjunction with the edge banding machine. The flexible guide strip device 700 includes a base plate 701, a stop bar 702, a rocker arm mechanism 703, and several second auxiliary wheels 704. The stop bar 702 is disposed on the base plate 701. The rocker arm mechanism 703 is disposed on the base plate 701 and drives the stop bar 702 to swing. The rocker arm mechanism 703 includes a second encoder 7031 for measuring and controlling the swing angle of the edge banding strip 301. Several second auxiliary wheels 704 are respectively installed on the base plate 701 and the rocker arm mechanism 703. The edge banding strip 301 is conveyed to the flexible guide strip device 700 after passing through the guide strip opening 101. A channel is provided between the stop bar 702 and the second auxiliary wheels 704 for the edge banding strip 301 to pass through.

[0040] It should be noted that the first and second encoders are photoelectric encoders, a type of measuring device. Photoelectric encoders can convert physical displacement in motion into digital signal output to achieve precise position detection and control. This includes the measurement of parameters such as rotational speed, angle, and linear displacement, and they are widely used in various mechanical and automation systems.

[0041] Specifically, the stop bar 702 is a flexible stop bar 702; in the process of using this application with the edge banding machine, the edge banding machine pulls the edge banding strip 301 to band the wood edge. When banding the wood edge, the speed at which the edge banding machine pulls the edge banding strip 301 fluctuates. Therefore, the second encoder 7031 needs to measure and control the swing angle of the edge banding strip 301 in real time, and respond to the changes in the tension of the edge banding machine in a timely manner and dynamically adjust the feeding speed.

[0042] In some implementations, such as Figures 19-20 As shown, the rocker arm mechanism 703 also includes a first rotating plate 7032, a second rotating plate 7033, a sixth cylinder 7034, and a swing wheel 7035. The first rotating plate 7032 and the second rotating plate 7033 are disposed above the baffle, and the first rotating plate 7032 and the second rotating plate 7033 are rotatably connected to the swing wheel 7035. One end of the first rotating plate 7032 is fixedly connected to the piston rod of the sixth cylinder 7034 and the rotating shaft of the second encoder 7031. When the edge banding machine starts and pulls the edge banding tape 301, the second encoder 7031 will detect the speed change of the edge banding tape 301, which causes the angle to swing. In real time, the first rotating plate 7032, the swing wheel 7035, and the second rotating plate 7033 will swing through the rotating shaft of the second encoder 7031. At this time, the baffle 702 and the second auxiliary wheel 704 will guide the edge banding tape 301 to the edge banding machine from both sides respectively. While the swing wheel 7035 moves, it will drive the edge banding tape 301 to swing.

[0043] Furthermore, the initial state is when the edge banding tape 301 is not yet pulled by the edge banding machine. When the pulling force of the edge banding machine increases, the second encoder 7031 will detect an angle change in the swing arm mechanism. The edge banding tape 301 will then come into contact with the second auxiliary wheel 704 and the swing wheel 7035, causing the edge banding tape 301 to swing towards the swing wheel 7035, thus changing the angle of the swing arm mechanism. At this time, the second motor 602 will increase its speed to deliver the edge banding tape 301, thereby matching the speed at which the edge banding machine pulls the edge banding tape 301. The second encoder 7031 will then drive the swing arm mechanism away from the swing wheel 7035. The direction of rotation; that is, the rotation of the first rotating plate 7032 drives the piston rod of the sixth cylinder 7034 to retract, and the second rotating plate 7033 is simultaneously pulled to rotate; so that the angle value of the encoder always remains fixed; if the tension of the edge banding machine decreases or gradually stops, the movement trend of the edge banding tape 301 will swing away from the swing wheel 7035, which will easily loosen and accumulate tape jamming; at this time, the second motor 602 will slow down the speed, and the second encoder 7031 will drive the swing arm mechanism to gradually return to the initial state, realizing the dynamic follow-up of the edge banding tape 301 output to the edge banding machine supply, ensuring that the edge banding tape 301 can be smoothly output.

[0044] In some implementations, such as Figures 19-20 As shown, the rotation shafts of several second auxiliary wheels 704 are respectively fixed on the base plate 701, the first rotating plate 7032 and the second rotating plate 7033. When the second encoder 7031 drives the swing arm mechanism to swing, the second auxiliary wheels 704 of the first rotating plate 7032 and the second rotating plate 7033 swing along with it. The stop bar 702, the swing wheel 7035 and the second auxiliary wheel 704 will guide the edge banding tape 301 to the edge banding machine from both sides respectively.

[0045] In some embodiments, the third cylinder 603, the fourth cylinder 605, and the fifth cylinder 6073 are cylinders with guide rods.
