Description

Technical Field

[0001] This invention relates to the field of semi-circular plate production technology, and in particular to a semi-circular plate pressing device and process for coffee table production. Background Technology

[0002] In the manufacturing process of coffee tables, semi-circular boards are widely used as a special board shape. Semi-circular boards are mostly made by bonding and pressing multiple layers of boards of different properties together to achieve a more beautiful and practical purpose. The production process of semi-circular boards is as follows: First, take out multiple layers of boards of different materials but the same shape and bond them together with glue. Then, put these multiple layers of boards into a pressing device for pressing to strengthen the bonding strength between the boards.

[0003] When existing pressing devices press multi-layer semi-circular plates, the uneven stress distribution between the center and edge areas is caused by the inconsistent distance from the edge to the center of the semi-circular plate. In addition, the semi-circular plates are mostly fixed by selected points, which also leads to uneven stress. During pressing, the stress near the fixed end is higher than that near the free end, resulting in quality problems of the pressed semi-circular plates. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the present invention provides a semi-circular plate pressing device and process for coffee table production.

[0005] The technical implementation of the present invention is as follows: a semi-circular plate pressing device for coffee table production, comprising: a base frame; a pressing device disposed on the base frame for pressing the semi-circular plate; a straightening strip disposed on the base frame for straightening the semi-circular plate; a straightening mechanism disposed on the base frame, wherein the straightening mechanism drives the straightening strip to wrap the plate, thereby preventing relative sliding between different layers of plates during pressing and buffering irregular stress on the periphery of the plate during pressing; and a fixing mechanism disposed on the base frame for tightly attaching the straightening strip to the periphery of the semi-circular plate.

[0006] Preferably, the straightening mechanism includes: mirror-distributed first motors, all fixedly connected to the base frame; mirror-distributed winding reels, all rotatably connected to the base frame, the winding reels being fixedly connected to the output shafts of the first motors; mirror-distributed traction lines, wound around adjacent winding reels, the traction lines being fixedly connected to the straightening belt; and an adjustment component, disposed on the base frame, for adjusting the traction position and traction direction of the mirror-distributed traction lines on the straightening belt.

[0007] Preferably, the adjustment assembly includes: mirror-distributed fixed frames, all fixed to the base frame; and mirror-distributed sliding rods slidably connected to adjacent fixed frames, wherein each sliding rod is rotatably connected to a transmission wheel, and the transmission wheel is used to guide adjacent traction lines.

[0008] Preferably, the fixing mechanism includes: mirror-distributed movable blocks, with mirror-distributed electric slide rails provided on the base frame, the movable blocks being fixed to sliders in adjacent electric slide rails on the base frame; mirror-distributed transmission frames, respectively fixed to adjacent movable blocks, the transmission frames being fixed to adjacent sliding rods, the transmission frames being provided with pressing rods, the pressing rods engaging with the sizing belt; and a push plate assembly, provided on the base frame, for pushing the semi-circular plate so that the semi-circular plate is tightly attached to the sizing belt.

[0009] Preferably, the axis of the traction line between the drive wheel and the straightening belt is parallel to the axis of the extrusion rod, to ensure that the straightening belt exerts the same extrusion force on the side of the semicircular plate.

[0010] Preferably, the pusher assembly includes: a first sliding frame slidably connected to the base frame, the first sliding frame being fixedly connected to an adjacent transmission frame, a rotating rod rotatably connected to the base frame, a second sliding frame slidably connected to the base frame, and the first sliding frame and the second sliding frame being transmitted to the adjacent rotating rod via transmission components; and an extrusion frame slidably connected to the second sliding frame, the extrusion frame being slidably connected to the base frame, and a spring being provided between the extrusion frame and the second sliding frame.

[0011] Preferably, the pusher assembly further includes: a first elastic strip fixedly connected to the second sliding frame; and a second elastic strip fixedly connected to the extrusion frame, wherein the second elastic strip is in extrusion engagement with the semi-circular plate.

[0012] Preferably, the system further includes: a mirror-distributed limiting frame, wherein the base frame is provided with mirror-distributed inclined slide grooves, the limiting frame is slidably connected to adjacent inclined slide grooves on the base frame, the transmission frame is slidably connected to adjacent extrusion rods, and the limiting frame is fixedly connected to adjacent extrusion rods.

[0013] Preferably, the system further includes: mirror-distributed tensioning wheels, all rotatably connected to the base frame, a second motor fixedly connected to the base frame, the mirror-distributed tensioning wheels being driven by a transmission component, the output shaft of the second motor being fixedly connected to one side of the tensioning wheel, and the mirror-distributed tensioning wheels cooperating with the regular belt drive.

[0014] A semi-circular plate pressing process for coffee table production, based on the aforementioned semi-circular plate pressing device for coffee table production, includes the following steps:

[0015] S1: Place the bonded semicircular plate on the base frame. Then, the slider in the electric slide rail on the base frame drives the mirror-distributed extrusion rods to move in opposite directions. The extrusion rods extrude and drive the aligning strip, so that the aligning strip adheres to the semicircular plate. At the same time, the slider in the electric slide rail on the base frame drives the extrusion frame to move. The extrusion frame drives the semicircular plate to move towards the aligning strip through the second elastic strip and extrudes the aligning strip, thereby completing the adhesion between the aligning strip and the semicircular plate. Then, control the slider in the electric slide rail on the base frame to stop moving.

[0016] S2: Start the first motor. The output shaft of the first motor drives the traction line to move. The traction line drives the straightening belt to move and fit and wrap the edge of the semi-circular plate. Then, turn off the first motor.

[0017] S3: During the process of the extrusion rod driving the sizing belt to move, the extrusion rod drives the limit frame to move. Under the limit of the inclined slide groove on the base frame, the limit frame drives the sizing belt to move to the left through the extrusion rod. At the same time, the second motor is started. The second motor drives the tension wheel to rotate. The tension wheel drives the sizing belt to stick to the semi-circular plate. The second motor is then turned off.

[0018] S4: Control the pressing device to press the semi-circular plate. After the semi-circular plate is pressed, remove it and control the pressing device to reset.

[0019] Compared with the prior art, the present invention has the following advantages: The present invention provides wrapping support for the semi-circular plate through the aligning belt, balancing the stress distribution of the semi-circular plate at various points during the pressing process and buffering the stress generated during pressing. It also prevents relative sliding between different layers of plates during pressing, improving the stability of the semi-circular plate during the pressing process and thus improving the output quality of the pressed semi-circular plate. Through the cooperation of the transmission frame and the sliding rod, the traction direction of the traction line is synchronously adjusted according to the size of the semi-circular plate, ensuring that the aligning belt and the side extrusion pressure of the semi-circular plate remain consistent, further guaranteeing the stability of the semi-circular plate during pressing. Through the cooperation of the limiting frame and the tensioning wheel, the aligning belt is driven in segments, ensuring that each part of the aligning belt remains in contact with the side of the semi-circular plate, preventing gaps between the aligning belt and the semi-circular plate, which would affect the pressing quality of the semi-circular plate.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0029] A semi-circular plate pressing device for coffee table production, such as Figures 1-3 As shown, it includes: a base frame 1, a pressing device 2, and a straightening belt 3; the pressing device 2, mounted on the base frame 1, is used to press the semi-circular plate; the straightening belt 3, mounted on the base frame 1, is used to straighten the semi-circular plate; the straightening mechanism, mounted on the base frame 1, drives the straightening belt 3 to wrap the multi-layered board, so as to prevent relative sliding between different layers of board during pressing, and at the same time buffer the irregular stress on the periphery of the board during pressing; and the fixing mechanism, mounted on the base frame 1, is used to press the straightening belt 3 tightly against the periphery of the semi-circular plate.

[0030] In the above scheme, the aim is to provide circumferential wrapping support for the semicircular plate, thereby ensuring the uniform distribution of stress during pressing. The pressing device 2 is an existing device, including a frame 201, a hydraulic push rod 202 and an extrusion plate 203. The frame 201 is equipped with a control panel, and the hydraulic push rod 202 is electrically connected to the control panel on the frame 201. The straightening strip 3 is made of soft material and its thickness is the same as that of the semicircular plate before pressing. It is used to ensure the wrapping of the semicircular plate and the fixation of different layers of plates during the entire pressing process.

[0031] Workflow: First, place the composite board on the base frame 1. Then, the user controls the fixing mechanism to simultaneously fix the semi-circular board and the aligning belt 3. After fixing, the user pulls the aligning belt 3 through the aligning mechanism so that the aligning belt 3 completely adheres to and wraps the side of the semi-circular board. The user starts the hydraulic push rod 202 through the control panel. The telescopic end of the hydraulic push rod 202 extends and drives the extrusion plate 203 to move downward. The extrusion plate 203 presses the semi-circular board until the semi-circular board is pressed. Then, the user controls the telescopic end of the hydraulic push rod 202 to retract through the control panel. The telescopic end of the hydraulic push rod 202 drives the extrusion plate 203 to move upward and reset. At this time, the semi-circular board is pressed. The user removes the pressed semi-circular board from the base frame 1. The pressing is complete.

[0032] like Figure 2 and Figure 3 As shown, the straightening mechanism includes: mirror-distributed first motors 4, all fixedly connected to the base frame 1; mirror-distributed winding wheels 5, all rotatably connected to the base frame 1, with the winding wheels 5 fixedly connected to the output shaft of the first motors 4; mirror-distributed traction lines 6, wound around adjacent winding wheels 5, with the traction lines 6 fixedly connected to the straightening belt 3, and the straightening belt 3 in a pressing fit with the semi-circular plate; and an adjustment component, set on the base frame 1, used to adjust the traction position and traction direction of the mirror-distributed traction lines 6 on the straightening belt 3.

[0033] like Figure 3 As shown, the adjustment assembly includes: mirror-distributed fixed frames 7, all fixed to the base frame 1; mirror-distributed sliding rods 8, slidably connected to adjacent fixed frames 7, with a transmission wheel 9 rotatably connected to the sliding rod 8. The transmission wheel 9 is used to guide adjacent traction lines 6. During the use of this device, the axis of part of the traction line 6 between the transmission wheel 9 and the straightening belt 3 is parallel to both the front and rear sides of the semicircular plate, in order to ensure that the straightening belt 3 exerts the same pressure on the side of the semicircular plate.

[0034] In the above scheme, the aim is to adjust the traction direction of the sizing belt 3 according to the different sizes of the semicircular plates, so as to ensure that the sizing belt 3 is tightly attached to the front and rear sides of the semicircular plates, prevent gaps or excessive compression between the sizing belt 3 and the side of the semicircular plates, and wrap and support the side wall of the semicircular plates. The traction line 6 is a steel wire rope, which is used to ensure its tensile strength and toughness. The first motor 4 is electrically connected to the control panel on the frame 201.

[0035] Workflow: After the semi-circular plate is fixed, the user starts the first motor 4 through the control panel on the frame 201. Taking the front first motor 4 as an example, the first motor 4 drives the winding wheel 5 to rotate. The winding wheel 5 rotates and gathers the traction line 6 on it. The traction line 6 is guided by the direction of the transmission wheel 9 to pull the front part of the straightening belt 3 from right to left, so that the inner side of the straightening belt 3 is close to the semi-circular plate, thereby ensuring that the straightening belt 3 wraps and supports the side of the semi-circular plate, so that the stress on the edge of the semi-circular plate is more evenly distributed during pressing.

[0036] like Figures 2-5 As shown, the fixing mechanism includes: mirror-distributed moving blocks 10, with mirror-distributed electric slide rails on the base frame 1, and the moving blocks 10 fixedly connected to the sliders in adjacent electric slide rails on the base frame 1; mirror-distributed transmission frames 11, respectively fixedly connected to adjacent moving blocks 10, the transmission frames 11 being fixedly connected to adjacent sliding rods 8, the transmission frames 11 being provided with pressing rods 12, the pressing rods 12 being pressed and engaged with the sizing belt 3; and a push plate assembly, located on the base frame 1, used to push the semi-circular plate so that the semi-circular plate is tightly attached to the sizing belt 3.

[0037] like Figures 3-6 As shown, the pusher assembly includes: a first sliding frame 13 with a mirror-distributed arrangement, slidably connected to the base frame 1, the first sliding frame 13 being fixedly connected to the adjacent transmission frame 11, a rotating rod 14 with a mirror-distributed arrangement rotatably connected to the base frame 1, a second sliding frame 15 being slidably connected to the base frame 1, and the first sliding frame 13 and the second sliding frame 15 being transmitted to the adjacent rotating rod 14 through a transmission component; and a pressing frame 16, slidably connected to the second sliding frame 15, the pressing frame 16 being slidably connected to the base frame 1, and a spring being provided between the pressing frame 16 and the second sliding frame 15.

[0038] like Figure 3 , Figure 4 and Figure 6 As shown, the push plate assembly also includes: a first elastic strip 17, fixedly connected to the second sliding frame 15; and a second elastic strip 18, fixedly connected to the extrusion frame 16, wherein the second elastic strip 18 is extruded into the semi-circular plate.

[0039] In the above scheme, the aim is to fix the semicircular plate and adjust the relative position of the sliding rod 8 and the transmission wheel 9 according to the different sizes of the semicircular plate, thereby changing the shape of the sizing belt 3 so that the sizing belt 3 wraps around and adheres to the surface of the semicircular plate. The electric slide rails distributed in a mirror on the base frame 1 are all electrically connected to the control panel on the frame 201. The extrusion rod 12 is used to provide extrusion force to the sizing belt 3. The sizing belt 3 is subjected to a force from the outside to the inside and is pressed tightly against the side of the semicircular plate. The extrusion frame 16 and the second elastic strip 18 are used to provide extrusion force to the semicircular plate, so that the semicircular plate extrudes the sizing belt 3. Thus, the stress on the semicircular plate is reduced through bidirectional extrusion force. To achieve balance, the first sliding frame 13 and the rotating rod 14 are driven by gears and racks, and the second sliding frame 15 and the rotating rod 14 are driven by gears and racks. The transmission ratio between the first sliding frame 13 and the second sliding frame 15 is the same as the length-to-width ratio of the semicircular plate. That is, this device only performs pressing processing on semicircular plates of the same specification (same specification means that the length-to-width ratio of semicircular plates of different sizes is the same). The first elastic strip 17 is a rectangular strip, and the second elastic strip 18 is a long strip with an L-shaped cross section. Both are made of soft rubber. The second elastic strip 18 is used to ensure that the semicircular plate is always supported during the pressing process.

[0040] Workflow: After placing the semi-circular plate on the upper side of the base frame 1, the user controls the sliders in the two electric slide rails on the base frame 1 to move in opposite directions via the control panel on the frame 201. Taking the front moving block 10 as an example, the slider in the electric slide rail of the base frame 1 drives the moving block 10 to move backward. The moving block 10 drives the transmission frame 11 to move backward. The transmission frame 11 drives the sliding rod 8 and the pressing rod 12 to move backward together. The pressing rod 12 pushes the front part of the sizing belt 3 to move backward. The sliding rod 8 drives the traction line 6 to move backward together via the transmission wheel 9. During this process, the first motor 4 drives the winding wheel 5 to release the corresponding allowance of the traction line 6, thereby ensuring that the sizing belt 3 and the traction line 6 move backward in a straight line together until the pressing rod 12 fixes the sizing belt 3 to the semi-circular plate. The user then controls the sliders of the electric slide rail on the base frame 1 to stop moving.

[0041] When the transmission frame 11 moves backward, the transmission frame 11 drives the first sliding frame 13 to move backward together. The first sliding frame 13 drives the rotating rod 14 to rotate through the transmission component. The rotating rod 14 drives the second sliding frame 15 to move to the right through the transmission component. The second sliding frame 15 drives the extrusion frame 16 and the second elastic strip 18 to move to the right together through the spring, and extrudes and fixes the semi-circular plate (that is, drives the semi-circular plate to move towards the regularization belt 3, so that the semi-circular plate extrudes the inner side of the regularization belt 3), so that the side of the semi-circular plate is in close contact with the regularization belt 3.

[0042] Based on the above embodiments, such as Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, it also includes: a mirror-distributed limiting frame 19, a base frame 1 with mirror-distributed inclined slide grooves, the limiting frame 19 being slidably connected to adjacent inclined slide grooves on the base frame 1, the transmission frame 11 being slidably connected to adjacent extrusion rods 12, the limiting frame 19 being fixedly connected to adjacent extrusion rods 12, and also includes: mirror-distributed tensioning wheels 20, all rotatably connected to the base frame 1, a second motor 21 being fixedly connected to the base frame 1, the mirror-distributed tensioning wheels 20 being driven by a transmission component, the output shaft of the second motor 21 being fixedly connected to one side of the tensioning wheel 20, and the mirror-distributed tensioning wheels 20 being driven by the regularizing belt 3.

[0043] In the above scheme, the aim is to further improve the fit between the sizing belt 3 and the semi-circular plate. Equally spaced limiting strips are provided on the outer side of the sizing belt 3. Equally spaced limiting strips are also provided on the opposite sides of the mirror-distributed extrusion rods 12. The limiting strips on the extrusion rods 12 and the sizing belt 3 are press-fitted together. The distance between the mirror-distributed inclined grooves on the base frame 1 gradually increases from left to right. That is, when the extrusion rods 12 are used to fix the sizing belt 3 and the semi-circular plate, the limiting frame 19 is pressed by the adjacent inclined grooves on the base frame 1, causing the extrusion rods 12 and the sizing belt 3 to move to the left. The tensioning wheel 20 is also provided with circumferential... The array of limiting strips, the limiting strips on the extrusion rod 12 and the tensioning wheel 20 are all used to push the sizing belt 3 to prevent the sizing belt 3 from being too difficult to be pulled to the side of the semi-circular plate due to excessive friction between it and the side of the semi-circular plate. Since the sizing belt 3 is made of soft material, when the sizing belt 3 is stretched, the side of the sizing belt 3 closest to the mirror-distributed traction line 6 (left side) is stretched and gradually becomes thinner. Due to the different forces on the sizing belt 3, the degree of stretching of the sizing belt 3 gradually decreases from left to right. The mirror-distributed tensioning wheels 20 are driven by a spur gear set. The second motor 21 is electrically connected to the control panel on the frame 201.

[0044] Work process: Taking the front limiting frame 19 as an example, during the process of the extrusion rod 12 moving backward, the extrusion rod 12 drives the limiting frame 19 to move backward. During this process, the limiting frame 19 and the inclined slide groove on the base frame 1 are squeezed and the extrusion rod 12 is driven to move to the left. The upper limit bar of the extrusion rod 12 cooperates with the upper limit bar of the sizing belt 3 and drives the sizing belt 3 to move to the left, thereby ensuring that the sizing belt 3 can move to the left normally.

[0045] Taking the front tensioning wheel 20 as an example, the user starts the second motor 21 through the control panel on the frame 201. The output shaft of the second motor 21 drives the tensioning wheel 20 to rotate counterclockwise (viewed from above). The upper limit bar of the tensioning wheel 20 cooperates with the upper limit bar of the straightening belt 3 to stretch the straightening belt 3 on the right side, thereby unifying the thickness of each part of the straightening belt 3, ensuring that the internal stress of the straightening belt 3 is evenly distributed, and preventing the straightening belt 3 from being difficult to move due to friction between it and the semi-circular plate, further ensuring the tightness between the straightening belt 3 and the side of the semi-circular plate.

[0046] Based on the above embodiments, such as Figures 1-7 As shown, a semi-circular plate pressing process for coffee table production, based on the aforementioned semi-circular plate pressing device for coffee table production, includes the following steps:

[0047] S1: Place the bonded semicircular plate on the base frame 1. Then, the slider in the electric slide rail on the base frame 1 drives the mirror-distributed extrusion rods 12 to move in opposite directions. The extrusion rods 12 extrude and drive the aligning belt 3, so that the aligning belt 3 adheres to the semicircular plate. At the same time, the slider in the electric slide rail on the base frame 1 drives the extrusion frame 16 to move. The extrusion frame 16 drives the semicircular plate to move towards the aligning belt 3 through the second elastic strip 18 and extrudes the aligning belt 3, thereby completing the adhesion between the aligning belt 3 and the semicircular plate. Then, control the slider in the electric slide rail on the base frame 1 to stop moving.

[0048] S2: Start the first motor 4. The output shaft of the first motor 4 drives the traction line 6 to move. The traction line 6 drives the straightening belt 3 to move and fit and wrap the edge of the semi-circular plate. Then, turn off the first motor 4.

[0049] S3: During the process of the extrusion rod 12 driving the sizing belt 3 to move, the extrusion rod 12 drives the limiting frame 19 to move. Under the limitation of the inclined slide groove on the base frame 1, the limiting frame 19 drives the sizing belt 3 to move to the left through the extrusion rod 12. At the same time, the second motor 21 is started. The second motor 21 drives the tension wheel 20 to rotate. The tension wheel 20 drives the sizing belt 3 to stick to the semi-circular plate. The second motor 21 is then turned off.

[0050] S4: Control the pressing device 2 to press the semi-circular plate. After the semi-circular plate is pressed, remove it and control the pressing device 2 to reset.

[0051] The technical principles of the embodiments of the present invention have been described above with reference to specific examples. These descriptions are merely for explaining the principles of the embodiments of the present invention and should not be construed as limiting the scope of protection of the embodiments of the present invention in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the embodiments of the present invention.

The extrusion frame (16) drives the semicircular plate to move towards the regularization belt (3) through the second elastic strip (18) and extrudes the regularization belt (3), thereby completing the adhesion between the regularization belt (3) and the semicircular plate. Control the slider in the electric slide rail on the base frame (1) to stop moving. S2: Start the first motor (4), the output shaft of the first motor (4) drives the traction line (6) to move, the traction line (6) drives the regular belt (3) to move and fit and wrap the edge of the semi-circular plate, and then turn off the first motor (4). S3: During the process of the extrusion rod (12) driving the sizing belt (3) to move, the extrusion rod (12) drives the limit frame (19) to move. Under the limit of the inclined slide groove on the base frame (1), the limit frame (19) drives the sizing belt (3) to move to the left through the extrusion rod (12). At the same time, the second motor (21) is started. The second motor (21) drives the tension wheel (20) to rotate. The tension wheel (20) drives the sizing belt (3) to stick to the semicircular plate. The second motor (21) is then turned off. S4: Control the pressing device (2) to press the semi-circular plate. After the semi-circular plate is pressed, remove it and control the pressing device (2) to reset.
