Description

[0002] In the existing plate edge sealing equipment, a pressing device is usually arranged above the conveying mechanism to press the plate during the edge sealing process, and the plate is pushed by the conveying force of the conveying mechanism. However, the pressing device usually only adopts a single pressing wheel structure or a double parallel belt structure to press the plate.

[0003] However, such devices have obvious limitations when adapting to different specifications of plates. For example, for wide-edge plates, the single pressing wheel structure is prone to uneven pressing during the pushing process due to the gap between the wheels, which may cause fluctuations in the middle of the plate. The double parallel belt structure may cause the edges of the plate to lift due to the gap between the two belts. For narrow-edge plates, the single pressing wheel structure is prone to shaking when the pressing point is offset, affecting the stability of the processing. The double parallel belt structure also has the problem of unstable pressing, which not only affects the stability of the plate pushing, but also reduces the edge sealing accuracy of the plate, and restricts the production efficiency.

DETAILED DESCRIPTION

[0019] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0020] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the modules or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] like Figures 1-7 A pressing device is shown, which is used for a plate edge banding machine. The plate edge banding machine includes a frame 1, a conveying mechanism (not shown in the figure) and an edge banding processing area 13. The pressing device includes a pressing mechanism, which is arranged above the conveying mechanism and connected to the frame 1. It is used to stably press the plate during the process of conveying the plate by the conveying mechanism, so as to ensure the stable direction of the plate during the edge banding process and improve the edge banding accuracy.

[0023] The pressing mechanism includes a crossbeam 2, a pressing wheel assembly 3, and a belt assembly 4. The pressing wheel assembly 3 is arranged on one side of the crossbeam 2 and is close to the edge banding processing area 13. The pressing wheel assembly 3 includes at least one first pressing wheel 31. The first pressing wheel 31 can rotate in a direction perpendicular to the sheet conveying direction and is used to press the sheet on the side close to the edge banding processing area 13, thereby preventing the sheet on this side from warping or shaking during the edge banding operation. The belt assembly 4 is adjacent to the pressing wheel assembly 3 and is located on the side away from the edge banding processing area 13. It is used to press the sheet on the side close to the pressing wheel assembly 3. Through the coordinated pressing action of the pressing wheel assembly 3 and the belt assembly 4 at different positions, stable conveying and uniform pressing of sheets of different widths can be achieved, which can not only avoid fluctuations in the middle of the wide-side sheet, but also prevent the pressure point offset or edge warping of the narrow-side sheet.

[0024] Furthermore, the first pressing wheel 31 can be provided in plurality, and the plurality of first pressing wheels 31 are distributed at intervals along the length direction of the beam 2 at the bottom of the beam 2 to form a continuous pressing support surface in the plate conveying direction, thereby improving the pressing uniformity and stability.

[0025] Specifically, the pressure wheel assembly 3 may also include a second pressure wheel 32, which is provided in plurality and arranged at intervals along the length direction of the beam 2. The plurality of first pressure wheels 31 and the plurality of second pressure wheels 32 are arranged in an alternating manner, thereby forming staggered pressure during the sheet conveying process, further improving the uniformity of force on the sheet on one side of the edge banding processing area 13.

[0026] In other embodiments, the pressure wheel assembly 3 and the belt assembly 4 can be arranged in multiple combinations to meet the pressing needs of different specifications of plates. For example, they can be arranged in the order of "pressure wheel assembly 3-belt assembly 4" or in the order of "pressure wheel assembly 3-belt assembly 4-pressure wheel assembly 3", or even in the order of "pressure wheel assembly 3-belt assembly 4-pressure wheel assembly 3-belt assembly 4", and so on. However, it should be noted that in order to ensure that the plate is stably pressed near the edge sealing processing area 13, the end closest to the edge sealing processing area 13 should always be arranged in the combination of the pressure wheel assembly 3 and the belt assembly 4, so as to ensure the uniformity of pressing and the stability of conveying of the plate in the key processing area.

[0027] The pressure wheel assembly 3 can be arranged as a single row of pressure wheels, including only a row of first pressure wheels 31, or as a double row of pressure wheels, including first pressure wheels 31 and second pressure wheels 32, and the first pressure wheels 31 and the second pressure wheels 32 are staggered along the length direction of the cross beam 2 to improve the uniformity and stability of pressing the plate, effectively avoiding the plate from deviating, shaking or fluctuating in the middle during pushing. Of course, according to the actual structure, multiple rows of pressure wheels can be arranged.

[0028] Referring to Figure 1 The belt assembly 4 includes a first pulley 41 arranged at one end of the cross beam 2, a second pulley 42 arranged at the other end of the cross beam 2, and a transmission belt 43 arranged between the first pulley 41 and the second pulley 42. The pressing surface of the transmission belt 43 and the pressing surface of the first pressure wheel 31 or / and the second pressure wheel 32 are located on the same plane, so as to ensure the smooth pressing of the plate on the side away from the edge sealing processing area 13 and close to the pressure wheel assembly 3. The cross beam 2 is also provided with a tensioning adjusting assembly 7 for adjusting the tension of the transmission belt 43 to adapt to stable conveying under different working conditions. The cross beam 2 is also provided with two belt expanding pulleys 44 arranged near the first pulley 41 and the second pulley 42 respectively for assisting the tensioning and guiding of the transmission belt 43, so as to ensure that the transmission belt 43 maintains stable stress during operation and avoids deviation or relaxation, thereby improving the uniform pressing effect of the plate by the pressing mechanism and the stability of edge sealing processing.

[0029] Referring to Figure 5 The tensioning adjusting assembly 7 includes a mounting seat 71, a moving seat 72 in sliding connection with the mounting seat 71, and an adjusting shaft 73 connected to the moving seat 72. The mounting seat 71 is also provided with a fixed plate 74, and the adjusting shaft 73 is screwed to the fixed plate 74. The mounting seat 71 is fixed to the cross beam 2, and the first pulley 41 or the second pulley 42 is rotatably mounted to the moving seat 72. When the adjusting shaft 73 is rotated, the moving seat 72 can drive the first pulley 41 or the second pulley 42 to move along the cross beam, thereby changing the distance between the first pulley 41 and the second pulley 42 to achieve precise tensioning adjustment of the transmission belt 43.

[0030] With reference to Figure 2 The pressing mechanism further comprises a buffer assembly 5, which comprises a first support 51, a first pressing wheel 52 connected to the bottom end of the first support 51 and abutting against the transmission belt 43, and a buffer 53 hingedly connected at one end to the top end of the first support 51 and at the other end to the crossbeam 2. The buffer assembly 5 can provide elastic adjustment when there is a slight change in the thickness or surface height of the plate, thereby avoiding excessive impact or pressure on the surface of the plate.

[0031] In the present embodiment, the buffer 53 of the pressing mechanism can provide elastic adjustment for slight thickness changes or surface undulations of the plate during plate conveying and edge sealing. Specifically, when the plate slightly fluctuates or locally rises on the conveying mechanism, the buffer 53 can slightly move or compress accordingly, thereby maintaining the continuous and effective pressing of the plate by the pressing wheel or the pressing wheel, avoiding the plate from deviating, shaking or edge rising due to fluctuation, while reducing the risk of excessive impact or pressure on the surface of the plate, improving the stability and processing precision of the plate during edge sealing processing. In addition, the buffer mechanism can also absorb the impact force during conveying, allowing the plate to run smoothly at high speed.

[0032] In the present embodiment, the buffer 53 can be provided in the form of a gas cylinder, or in the form of a spring, rubber pad or other elastic element. Through the elastic deformation of the gas cylinder or elastic element, the buffer 53 can adaptively adjust the slight thickness changes or surface undulations of the plate during plate pushing, so that the pressing wheel or the pressing wheel always maintains effective pressing on the plate, thereby preventing the plate from shaking, deviating or rising, while reducing the risk of excessive pressure or damage to the surface of the plate, improving the stability of edge sealing processing and the consistency of the product.

[0033] Specifically, the bottom of the crossbeam 2 is provided with a connecting shaft 23, and the first support 51 is provided with a through hole 513 and is hingedly connected to the connecting shaft 23; the first support 51 is provided with a first connecting arm 511 and a second connecting arm 512 arranged in an upper and lower manner, and the first pressing wheel 52 is rotatably installed at the bottom end of the second connecting arm 512; the top end of the first connecting arm 511 is provided with a hinge hole 514, and one end of the buffer 53 is hingedly connected to the hinge hole 514 at the top end of the first connecting arm 511; the top of the crossbeam 2 is provided with a mounting plate 21 along the length direction thereof, and the mounting plate 21 is provided with a connecting column 22; the other end of the buffer 53 is provided with a connecting hole and is hingedly connected to the connecting column 22.

[0034] With reference to Figure 7The device further comprises a downward pressing assembly 6, which comprises a second support 61, a second pressing wheel 62, and a driving member 63. One end of the second support 61 is hingedly connected to the bottom end of the cross beam 2, and the second pressing wheel 62 is rotatably connected to the other end of the second support 61 and abuts against the transmission belt 43. The mounting plate 21 is provided with a connecting rod 24, one end of the driving member 63 is hingedly connected to the other end of the second support 61, and the other end is hingedly connected to the connecting rod 24. When the driving member 63 is actuated, the second support 61 drives the second pressing wheel 62 to press downward on the transmission belt 43, so that the transmission belt 43 is tightly abutted against the conveying mechanism and generates a synchronous conveying effect, thereby enhancing the pushing force on the plate.

[0035] Specifically, the driving member 63 can be a pneumatic cylinder, one end of which is hingedly connected to the second support 61, and the other end is hingedly connected to the connecting rod 24 on the cross beam 2. When the pneumatic cylinder is extended or retracted, it can drive the second support 61 to move up and down, thereby driving the second pressing wheel 62 to exert pressure on the transmission belt 43, realizing stable pressing and pushing of the plate during conveying.

[0036] In this embodiment, multiple connecting columns 22 can be arranged along the length direction of the mounting plate 21, and multiple buffer assemblies 5 can be provided and connected to the corresponding connecting columns 22 one by one, so as to meet the needs of long plates or multi-point pressing.

[0037] In this embodiment, the first pulley 41, the second pulley 42, the belt expander 44, the first pressing wheel 52, and the second pressing wheel 62 are all provided with a belt clamping groove 54, which is used for embedding the transmission belt 43 therein, thereby realizing reliable positioning and stable transmission of the transmission belt, preventing slipping or displacement during operation, and ensuring uniform pressing of the plate by the pressing mechanism and smoothness of the conveying process.

[0038] Further, the rack 1 can be provided with a driving motor 9, a sliding seat 11, and an adjusting rod 93 connected to the sliding seat 11. The adjusting rod 93 is in transmission connection with the driving motor 9, and the pressing mechanism is installed on the sliding seat 11. When the driving motor 9 drives the adjusting rod 93 to rotate, the sliding seat 11 can drive the pressing mechanism to rise and fall as a whole, so as to adapt to workpieces of different thicknesses, realize efficient pressing and conveying, and effectively improve the precision and production efficiency of edge sealing.

[0039] It should be noted that the sliding seat 11 is connected to the rack 1 through a structure of a sliding block cooperating with a guide rail. The sliding block slides along the guide rail, so that the sliding seat 11 can move stably on the rack 1, thereby driving the pressing mechanism to realize lifting adjustment, so as to adapt to plates of different thicknesses and ensure the stability of the pressing process.

[0040] Specifically, the device further comprises a transmission converter 92 connected with the adjusting rod 93, and the transmission converter 92 is in transmission connection with the output end of the driving motor 9 through a transmission shaft 91, so that the number of the driving motor 9 required can be reduced. The transmission converter 92 is used for changing the transmission direction of the driving motor 9, and a bevel gear structure can be adopted to change the rotation direction of the driving motor 9 by 90°, so that the adjusting rod 93 obtains the required driving force and movement direction, and the stability and efficiency of the lifting adjustment of the material pressing mechanism are ensured.

[0041] In the embodiment, the device further comprises a protective cover 12 used for covering the top and side of the transmission belt 43, which can effectively prevent the operator from touching the transmission belt 43 by mistake, and prevent dust, debris and other foreign matters from falling into the area of the transmission belt 43, so as to ensure the stable operation of the transmission belt 43 and the material pressing mechanism, and improve the safety and durability of the equipment.

[0042] The device further comprises a control assembly 8 installed on the cross beam 2, which can be electrically connected with the driving motor 9, and is used for controlling the lifting movement of the material pressing mechanism, so as to realize the automatic adaptation and pressing adjustment of different thicknesses of plates, and thus improve the stability and processing efficiency of the plate edge sealing process.

[0043] In summary, the material pressing device of the present application realizes the stable adaptation of various types of plates through the combined pressing structure of the pressing wheel assembly 3 and the belt assembly 4, avoids the problem that the single pressing wheel structure is prone to cause pressing gaps in the middle of the plate and cause fluctuations, overcomes the defect that the double parallel belt structure is prone to cause the edge of the plate to be raised, and provides concentrated and stable point pressure through the pressing wheel assembly 3 in the processing process, ensures firm side pressure holding during edge sealing, and provides continuous surface pressure support through the belt assembly 4 to prevent the other side of the plate from shaking or warping, so as to maintain a stable posture during plate conveying and edge sealing, and improve the edge sealing precision and processing efficiency.

[0044] The material pressing device of the present application is arranged with the pressing wheel assembly 3 on one side close to the edge sealing processing area 13 and the belt assembly 4 on the other side away from the edge sealing processing area 13, so that the pressing wheel assembly 3 and the belt assembly 4 form a cooperative pressing action on the plate at different positions, thereby realizing stable pressing and smooth pushing of plates of different widths. For wide-edge plates, this structure effectively eliminates the uneven pressing in the middle and the plate fluctuation phenomenon caused by the gap between the pressing wheels of the traditional single pressing wheel structure; for narrow-edge plates, the structure avoids the shaking problem caused by the deviation of the single pressing wheel structure, and overcomes the defect that the edge of the plate is raised due to the gap between the belts of the single belt structure, improves the conveying stability and pressing uniformity of the plate during the edge sealing process, and improves the edge sealing precision and production efficiency.

When an element is referred to as being "connected" with another element, it can be directly connected to the other element or indirectly connected to the other element.
