Description

Technical Field

[0002] Edge banding is the process of gluing and decorating the edges of furniture panels. It is mainly used for the cross-section finishing of materials such as solid wood and density boards. It has moisture-proof, protective and beautifying functions. Edge banding is usually performed with an edge banding machine. This process originated from traditional carpentry manual operations. With the development of material technology, three mainstream edge banding materials have gradually emerged: wood, PVC, and melamine. The adhesive and construction method should be selected according to different materials. After searching, a feeding device of an edge banding machine with the publication number CN219173561U was found. The patent proposes a conveying mechanism for an edge banding machine that can realize material storage and automatic feeding, avoiding the problem of increased workload of staff due to manual loading of existing edge banding machines. However, the furniture panels conveyed by the conveying mechanism of the edge banding machine are mainly wooden structures.

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0019] The present invention provides the following embodiments: Example 1 The embodiment of the present invention provides a feeding device for a furniture edge banding machine, such as Figure 1 As shown, a feeding device of a furniture edge banding machine includes a platform 1, a plate conveying mechanism 2 is provided on the platform 1, an auxiliary support mechanism 5 is provided on the front side of the platform 1, a plate processing mechanism 7 is provided on the right side of the plate conveying mechanism 2, and a fireproof mounting mechanism 9 is provided on the rear side of the platform 1; The fireproof mounting mechanism 9 includes a fireproof door frame 91, which is bolted to the top of the platform 1. A smoke detector is provided on the fireproof door frame 91. A number of sprinklers 92 are spaced and staggered on the front and back sides of the fireproof door frame 91. The sprinklers 92 are fixedly connected to the fireproof door frame 91, and the input ends of the sprinklers 92 are all connected to the supply structure 93.

[0020] The working principle and beneficial effects of the above technical solution are as follows: the furniture panels are transported in a straight line by the panel conveying mechanism 2 on the platform 1, ensuring that the furniture panels move along a fixed path; the auxiliary support mechanism 5 on the front side of the platform 1 provides support for the front end of the furniture panels, preventing the center of gravity of the furniture panels from shifting outward due to their large width, thereby preventing tilting or shifting, thereby ensuring transportation stability and ensuring the sliding passage of the furniture panels; before the furniture panels are transported to the panel conveying mechanism 2, the panel processing mechanism 7 on the right side cleans and guides the surface of the furniture panels to be edge-sealed; in the event of a fire in the furniture panels, the fire-proof mounting mechanism 9 extinguishes the fire; The smoke detector monitors the smoke concentration in the edge sealing area of the furniture board of the stand 1 in real time. When smoke generated in the early stage of a fire is detected, a signal is immediately sent to the control system. After receiving the signal, the control system activates the supply structure 93 to deliver the fire extinguishing medium to the nozzles 92 on the fire door frame 91. Several nozzles 92 spray the fire extinguishing medium in an interval and staggered arrangement, forming a cross-covered fire extinguishing area, ensuring that the fire source in the edge sealing area of the stand 1 is effectively extinguished or controlled; The present invention conveys furniture panels through a panel conveying mechanism 2. This design can ensure that the furniture panels move stably during edge sealing, have a good edge sealing effect, ensure the continuity of the edge sealing process, and can be adjusted according to the thickness of the furniture panels. The auxiliary support mechanism 5 adjusts the working surface width of the equipment by telescoping to avoid the furniture panels from sagging due to gravity during transportation, resulting in tilted transportation, and through lateral pressure, the furniture panels are made to fit closely against the panel conveying mechanism 2, thereby ensuring the edge sealing effect of the furniture panels. The panel processing mechanism 7 can pre-process the furniture panels to ensure the fitting strength of the furniture panel edge sealing. The fireproof mounting mechanism 9 can respond quickly to fires, and can greatly block the possibility of early fires in advance compared to manual inspections, thereby reducing equipment burn losses. The staggered spraying design of the nozzle 92 makes the fire extinguishing coverage rate higher, and the powder supply structure 10 allows the fireproof mounting mechanism 9 to perform repeated fire extinguishing, thereby reducing the cost of using fire extinguishing consumables.

[0021] Example 2 On the basis of Example 1, Figure 2 、 Figure 3 、 Figure 4 As shown, the plate conveying mechanism 2 includes a driving sprocket 21, which is arranged in a transmission groove 22, and the transmission groove 22 is arranged on the surface of the platform 1. A number of driven sprockets 23 are arranged horizontally on one side of the driving sprocket 21. The driving sprocket 21 and the number of driven sprockets 23 are all rotatably connected to the platform 1. The driving sprocket 21 and the number of driven sprockets 23 are connected by a chain plate 24. The driving sprocket 21 and the driven sprockets 23 are engaged with the chain plate 24. The bottom of the platform 1 is bolted to a driving motor 25, and the output shaft of the driving motor 25 is connected to one end of the driving sprocket 21 through a transmission structure. A clamping structure 3 is provided above the transmission groove 22, and a travel cleaning structure 4 is provided at the bottom of the transmission groove 22.

[0022] The clamping structure 3 includes a stand 31, which is bolted to the surface of the platform 1, and a linkage plate 32 is bolted to the front side of the stand 31. Four groups of curved plates 33 are arranged horizontally on the linkage plate 32, and the four groups of curved plates 33 are rotatably connected to the linkage plate 32. A limiting column 34 is provided on one side of the four groups of curved plates 33, and the limiting column 34 is fixedly connected to the linkage plate 32. The bottom of the four groups of curved plates 33 are rotatably connected to a pressing roller 35, and a cross bar 36 is provided above the linkage plate 32. The tops of the four groups of curved plates 33 are hinged to the cross bar 36, and a compression elastic member 37 is provided between the left end of the cross bar 36 and the linkage plate 32.

[0023] The travel cleaning structure 4 includes two sets of slide rails 41, which are bolted to the two side walls of the transmission groove 22 respectively. A cleaning plate 42 is provided at the bottom of the transmission groove 22. The two sides of the cleaning plate 42 are slidably connected to the two sets of slide rails 41 respectively. The top of the cleaning plate 42 is bolted to a brush head 43, and the bottom of the cleaning plate 42 is bolted to a scraper 44. A lead screw 45 is provided in the center of the transmission groove 22. The lead screw 45 passes through the cleaning plate 42 horizontally and is threadedly connected. Both ends of the lead screw 45 pass through and are rotatably connected to the left and right ends of the platform 1. A transmission motor 46 is bolted to the right side of the platform 1, and the output end of the transmission motor 46 is connected to the lead screw 45.

[0024] The working principle and beneficial effects of the above technical solution are as follows: when the furniture board passes through the board conveying mechanism 2, the driving motor 25 drives the driving sprocket 21 to rotate through the transmission structure, and the driving sprocket 21 engages with the chain plate 24 to transmit power to the driven sprocket 23, forming a continuous chain plate 24 conveying path, and the chain plate 24 circulates in the transmission groove 22. When the furniture board is placed on the upper surface of the chain plate 24, horizontal conveying is achieved by friction. At the same time, when the chain plate 24 drives the furniture board forward, the pressing roller 35 close to the furniture board is squeezed by the board, so that A single curved plate 33 rotates around the fulcrum on the linkage plate 32, and the single curved plate 33 pulls the cross bar 36 to move, causing the remaining curved plates 33 to rotate around the fulcrum on the linkage plate 32. The cross bar 36 stretches and compresses the elastic member 1 37, and the elastic force is transmitted to the pressing roller 35 through the cross bar 36 and the curved plate 33 to apply pressure to the furniture plate. When the furniture plate passes, the compressed elastic member 1 37 rebounds, pulling the cross bar 36 to reset, causing the four groups of curved plates 33 to rotate and reset, driving the pressing roller 35 to reset, and the limit column 34 limits the reset position of the curved plates 33. When the furniture board is edge-sealed, the debris generated will fall into the transmission groove 22. After accumulating for a certain period of time, the transmission motor 46 drives the screw 45 to rotate, driving the cleaning plate 42 to make a linear reciprocating motion along the slide rail 41. The brush head 43 contacts the lower surface of the chain plate 24, and the scraper 44 contacts the bottom of the transmission groove 22 to remove the adhered debris, dust and other impurities. The rotation direction of the screw 45 is controlled by the forward and reverse rotation of the transmission motor 46 to achieve regular or continuous cleaning, preventing the accumulation of impurities from affecting the life of the chain plate 24 and the transmission accuracy. The present invention achieves compression of the furniture panels by compressing the elastic member 37 and the contact roller. The elastic compression force ensures that the furniture panels and the chain plate 24 do not slide relative to each other. It is particularly suitable for thin furniture panels or furniture panels with smooth surfaces. The multi-point support design of the curved plate 33 disperses the pressure, avoiding warping of the edges of the furniture panels due to single-point force, and has a significant effect on controlling the flatness of large-sized furniture panels. The stroke cleaning structure 4 can remove dust accumulated in the chain plate 24 and the transmission groove 22, reduce the wear of the sprocket and the chain plate 24, and extend the service life of the chain plate 24.

[0025] Example 3 On the basis of Example 1, Figure 5 、 Figure 6As shown, the auxiliary support mechanism 5 includes two groups of auxiliary rods 51, and the two groups of auxiliary rods 51 are symmetrically arranged on the bottom surfaces of both ends of the platform 1. The two groups of auxiliary rods 51 are slidably connected in the hooks 52, and the hooks 52 are fixedly connected to the bottom surface of the platform 1. A number of through holes 53 are provided on the side surfaces of the two groups of auxiliary rods 51, and the left and right sides of the platform 1 are threadedly connected with connecting bolts 54, and the connecting bolts 54 are slidably connected in the through holes 53. A rolling groove rod 55 is provided on the front side of the platform 1, and the two ends of the rolling groove rod 55 are bolted to the two auxiliary rods 51 respectively. A number of auxiliary rollers 56 are arranged horizontally in the rolling groove rod 55, and the several auxiliary rollers 56 are rotatably connected to the rolling groove rod 55. An auxiliary push structure 6 is provided on the front side of the rolling groove rod 55.

[0026] The auxiliary push structure 6 includes an auxiliary push cross bar 61, which is arranged on the front side of the rolling groove rod 55. The two ends of the auxiliary push cross bar 61 are respectively bolted to the two groups of auxiliary rods 51. A number of auxiliary push baffles 62 are arranged in sequence on the top of the auxiliary push cross bar 61. The auxiliary push baffles 62 are all rotatably connected to the auxiliary push cross bar 61. A limit plate 63 is provided on one side of the auxiliary push baffles 62. The limit plate 63 is fixedly connected to the auxiliary push cross bar 61. A rotating elastic member is provided between the auxiliary push baffles 62 and the auxiliary push cross bar 61.

[0027] The working principle and beneficial effects of the above technical solution are as follows: the two sets of auxiliary rods 51 are slidably connected to the bottom surface of the platform 1 through the hooks 52, and can be adjusted in the width direction of the platform 1 to meet the support requirements of furniture panels of different widths and increase the working surface of the platform 1. The connecting bolts 54 pass through the through holes 53 on the auxiliary rods 51 and are threadedly connected to the platform 1 to fix the auxiliary rods 51. The auxiliary rollers 56 in the rolling groove rods 55 are in contact with the bottom surface of the furniture panels and roll with the movement of the furniture panels during the conveying process to reduce friction resistance, which is especially suitable for heavier or large-sized furniture panels. The auxiliary push baffle 62 maintains the initial tilt angle by rotating the elastic member. When the furniture panels pass through, the auxiliary push baffle 62 is squeezed and rotated and stores elastic potential energy, exerting lateral pressure on the furniture panels, so that the furniture panels are close to the vertical frame 31. After the furniture panels have completely passed, the auxiliary push baffle 62 is quickly reset under the action of the elastic force; The present invention provides multi-point support for extra-wide furniture panels or central hollow furniture panels through the rolling groove rod 55 and the auxiliary roller 56, preventing bending deformation due to deadweight, ensuring the flatness error of the furniture panels, and the rolling support disperses the impact force, reduces vibration during transportation, and reduces the risk of scratches on the surface of the furniture panels. In addition, the sliding design of the auxiliary rod 51 allows for rapid adjustment of the support spacing to accommodate furniture panels of different widths. The elastic force of the auxiliary push baffle 62 can enable the furniture panels to maintain a close fit with the panel conveying mechanism 2 when passing through the panel conveying mechanism 2, so that the forward and backward passing direction of the furniture panels remains unchanged. The inclination angle design of the baffle can effectively prevent the furniture panels from moving backward, and can also avoid scratches on the furniture panels by the auxiliary push baffle 62.

[0028] Example 4 On the basis of Example 1, Figure 2 、 Figure 6 、 Figure 7 As shown, the plate processing mechanism 7 includes a semi-enclosed shell 71, a semi-enclosed shell 71 is provided on one side of the stand 31, the semi-enclosed shell 71 is bolted to the stand 1, a cleaning roller 72 is rotatably connected in the semi-enclosed shell 71, a cleaning motor 73 is bolted to the top of the semi-enclosed shell 71, the output end of the cleaning motor 73 is connected to the top of the cleaning roller 72, a negative suction pipe 74 is provided on the rear side of the cleaning roller 72, the negative suction pipe 74 passes through and is fixedly connected to the semi-enclosed shell 71, a negative suction bin 75 is fixedly connected to the bottom of the stand 1, the other end of the negative suction pipe 74 is connected to the negative suction bin 75, and a positioning structure 8 is provided on one side of the semi-enclosed shell 71.

[0029] The positioning structure 8 includes a plurality of auxiliary rollers 81 . The auxiliary rollers 81 are disposed on the right side of the semi-enclosed shell 71 . The auxiliary rollers 81 are arranged transversely in sequence. The auxiliary rollers 81 are all rotatably connected to the stand 1 .

[0030] The working principle and beneficial effects of the above technical solution are as follows: the cleaning motor 73 drives the cleaning roller 72 (the surface of which is covered with a flexible material) to rotate at a high speed opposite to the forward direction of the furniture board, contacting the surface of the furniture board and removing dust, debris and oil through friction. The negative pressure generated by the negative suction chamber 75 sucks in and collects impurities raised during the cleaning process through the negative suction pipe 74. The semi-enclosed shell 71 is designed to guide the airflow from the surface of the furniture board to the negative suction pipe 74, enhancing the adsorption efficiency while preventing dust from overflowing. When the furniture board is undergoing pretreatment, the furniture board rolls in contact with the roller when passing through, reducing frictional resistance while ensuring a straight conveying path and avoiding deviation. The present invention utilizes a cleaning roller to clean furniture panels. This design can effectively enhance the surface adhesion of the furniture panels, and the design of the negative suction pipe 74 can effectively prevent the furniture panels from adhering to dust again after cleaning. At the same time, the auxiliary roller 81 can ensure that the furniture panels move in the correct direction when entering the panel conveying mechanism 2.

[0031] Example 5 On the basis of Example 1, Figure 6 、 Figure 8 As shown, the supply structure 93 includes a delivery pipe 931, which is nested and fixed on the top of the fireproof door frame 91. The other end of the delivery pipe 931 is threadedly connected to the reducing nozzle 932. The input end of the reducing nozzle 932 is threadedly connected to the connecting pipe 933. The input end of the connecting pipe 933 is connected to the powder supply structure 10.

[0032] The powder supply structure 10 includes a powder tank 101, which is bolted to the bottom of the stand 1. Fire extinguishing powder is provided in the powder tank 101. A connecting pipe 933 is passed through and fixedly connected to the left side of the powder tank 101, and a pressure pipe 102 is passed through and fixedly connected to the right side of the powder tank 101. The connecting pipe 933 and the pressure pipe 102 are arranged in a staggered manner. A pressure relief valve 103 is provided on the pressure pipe 102, and a relay pressure bin 104 is passed through and fixedly connected to the other end of the pressure pipe 102. An air compressor 105 is provided on one side of the powder tank 101, and the air compressor 105 is bolted to the bottom of the stand 1. The relay pressure bin 104 is connected to the input end of the air compressor 105. A tank mouth 106 is provided on the top of the powder tank 101, and a clamp-type tank cover 107 is nested and connected to the tank mouth 106.

[0033] The working principle and beneficial effects of the above technical solution are as follows: when the smoke detector on the fire door frame 91 detects that the smoke concentration exceeds the threshold, it sends an electrical signal to the control system. After receiving the signal, the control system starts the air compressor 105 bolted to the stand 1. The air compressor 105 continuously supplies pressurized gas to the relay pressure chamber 104, so that the relay pressure chamber 104 is filled with high-pressure air. When the pressure in the relay pressure chamber 104 reaches the limit value, the high-pressure air breaks through the pressure relief valve 103, passes through the pressure pipe 102 and enters the powder tank 101, so that the powder tank 101 The internal air pressure rises. Due to the staggered arrangement of the pressure pipe 102 and the connecting pipe 933, the connecting pipe is buried by the fire extinguishing powder. The pressure in the powder tank 101 acts on the fire extinguishing powder, pushing it through the connecting pipe 933 and into the delivery pipe 931. When it passes through the reducing nozzle 932 (with a reduced inner diameter), the Bernoulli principle is used to increase the flow rate of the fire extinguishing powder, forming a high-speed jet stream. The staggered nozzles 92 on the fireproof door frame 91 cover the fire source area. When the fire extinguishing powder in the powder tank 101 is sprayed, the clamp-type tank lid is opened to add powder to the powder tank 101. The present invention forms a three-dimensional coverage network by arranging a number of nozzles 92 spaced apart from each other and staggered in pairs. Compared with a straight line arrangement, the spray range can be expanded to avoid dead corners of fire sources. The design of the reduced-diameter nozzle 932 increases the spray speed, and the ability to penetrate the core area of the flame is significantly improved. The pressure pipe 102 and the connecting pipe 933 are arranged in a high and low staggered manner, which can not only prevent powder from flowing back into the pressure system, but also ensure that the fire extinguishing powder is completely emptied. The pressure relief valve 103 cooperates with the relay pressure chamber 104 to quickly discharge the gas into the powder tank 101 after generating sufficient high-pressure gas, ensuring that the fire extinguishing powder has sufficient initial velocity.
