The seat plate is usually a wooden board, and the shape of the seat cushion is adapted to the seat plate. The seat cushion includes a soft cushion and a cover cloth covering the seat surface of the soft cushion. The outer periphery of the cover cloth is connected to a circle of drawstrings. In order to facilitate covering the seat plate, the outer contour area of ​​the seat cushion must be larger than the outer contour area of ​​the seat plate. When processing and manufacturing this type of chair seat, workers are required to first place a seat cushion that matches the shape of the seat plate on the front of the seat plate. At this time, the outer peripheral part of the seat cushion exceeds the outer contour of the seat plate, and then the outer peripheral part of the seat cushion is flanged and fit on the back of the seat plate. After that, the flanged part is made close to the inner side of the back of the seat plate by tightening the two ends of the drawstring. However, this assembly method mainly relies on manual labor and has certain shortcomings.

[0003] Workers are required to manually flanging the seat cushions, and whether the flanging width is uniform depends on the workers' proficiency. The assembly efficiency is low, and the quality of the assembled seat is unstable.

[0026] The present invention provides a chair seat forming device, which has the following advantages over the prior art: 1. The equipment acts on the seat plate through the pressing mechanism and causes the seat cushion to deform, so that the flange part of the seat cushion is flanged toward the seat plate, and then the flange part is tightened by the pull rope on the cover cloth. The whole equipment has a high degree of automation. Workers only need to place the seat and connect the end of the pull rope to the pull wire mechanism. Workers do not need to manually flange the seat cushion, which not only improves the molding quality and efficiency of the seat, but also reduces the molding difficulty of the seat.

[0027] 2. The equipment has wide applicability and stable processing effect. It can evenly fold the flange of the seat cushion at one time and make it flanged to the back of the seat plate by pressing the seat plate with the pressing head. No matter the seat cushion and the seat plate of the chair are regular square or round, or the seat plate and the seat cushion are irregular heart-shaped or polygonal, the equipment can be used for seat forming processing.

[0028] 3. The horizontal plates arranged on the left and right sides of the supporting mechanism and used to install the second driving member can be deflected forward and backward and stay in the corresponding position, so that the tensioner can adapt to the extension direction of the pulling section of the pull rope, and while tightening the flange part, it can also prevent the pull rope from falling off the edge of the cover cloth.

[0029] 4. The supporting mechanism is connected to a contouring tooling, which is provided with a contouring groove matching the outer contour. When the pressure strip presses the seat plate, the seat cushion will sink into the contouring groove, and the side wall of the contouring groove will act on the flange portion and fold it into a vertical state. When the seat cushion sinks into the bottom of the contouring groove and deforms, the flange portion in the vertical state will further move closer to the inner side of the seat plate. This design reduces the difficulty of the flange portion moving closer to the inner side of the seat plate, makes the width of the flange portion fitted to the inner side of the seat plate more uniform, and improves the molding quality of the seat.

[0030] 5. The equipment is provided with a telescopic rod and a sliding seat, which is connected to the supporting mechanism, so that the supporting mechanism can adjust the front and rear position and the longitudinal position according to the chair seats of different specifications and sizes, so that the pressure head is always facing the middle of the seat plate, ensuring that the pressure head can act on the seat plates of different specifications and sizes.

DETAILED DESCRIPTION

[0032] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0034] like Figure 1-10 As shown, the specific implementation of the present invention is as follows: The present invention provides a chair seat forming device, comprising: Frame 5, which is a support member of the seat molding equipment; The supporting mechanism is arranged on the frame 5 and is used to support the seat cushion and the seat plate 1 which are laid flat in sequence; the seat plate 1 is usually a wooden plate, the seat cushion comprises a cushion 2 and a cover cloth 3 covering the cushion 2, a pull rope 31 is connected around the outer periphery of the cover cloth 3, and two ends of the pull rope 31 are exposed outside the cover cloth 3 and form two pulling sections 32; The pressing mechanism 7 is arranged on the frame 5 and located above the supporting mechanism; it comprises a first driving member 72 and a pressing head 71, the first driving member 72 is connected to the pressing head 71 and can drive the pressing head 71 to press the seat plate 1 downward and cause the seat cushion to deform, so that the outer peripheral part of the seat cushion is folded toward the inner side of the seat plate 1 and forms a flange part 4; The wire pulling mechanism 9 is symmetrically arranged on both sides of the supporting mechanism; the wire pulling mechanism 9 can replace the manual operation of the worker, which can simplify the difficulty of tightening the pull rope 31 and is more labor-saving to operate. The wire pulling mechanism 9 includes a second driving member 92 and a tensioner 93 for connecting the corresponding ends of the pull rope 31 of the seat cushion; the second driving member 92 is connected to the tensioner 93 and can drive the tensioner 93 to move in the left and right directions to tighten the pull rope 31, so that the flange portion 4 of the seat cushion is tightened and fits against the inner side of the seat plate 1.

[0035] Furthermore, in this embodiment, taking the special-shaped seat plate 1 and seat cushion as examples, before placing the two on the supporting mechanism, the opposite sides of the flange portion 4 have been manually flanged to the inner side of the seat plate 1 and fixed by nails 4a to form two positioning portions 41. The purpose is to make the side connecting portions 42 on the other two sides easier to flange and reduce the difficulty of flanging. The design of the positioning portion 41 is only an auxiliary structure and is not absolutely necessary. Even if the positioning portion 41 is not fixed to the seat plate 1 by nails 4a, it does not affect the overall flanging of the flange portion 4 in this embodiment.

[0036] Further, if Figure 6-8 As shown in the figure, in order to reduce the difficulty of flanging the flanged portion 4 and improve the molding quality of the seat, a profiling tool 6 for contacting the seat cushion is connected to the upper end of the supporting mechanism, and the upper end surface of the profiling tool 6 has a profiling groove 61 with an open upper end and matching the shape and size of the outer contour of the seat plate 1; when the pressure head 71 presses the back of the seat plate 1 downward, the seat cushion sinks downward into the profiling groove 61, and the flanged portion 4 is acted upon by the side wall of the profiling groove 61 and moves closer to the back of the seat plate 1; the profiling groove 61 of the profiling tool 6 can play a role in guiding The side connection part 42 in the vertical state is easily turned toward the back of the seat plate 1, thereby reducing the difficulty of the flanged part 4 to approach the back of the seat plate 1; when the seat cushion sinks to the bottom of the profiling groove 61, it will contact and deform with the bottom of the profiling groove 61 under the action of the pressing head 71 pressing the seat plate 1, so that the side connection part 42 in the vertical state is turned toward the back of the seat plate 1, thereby making the side connection part 42 evenly close to the back of the seat plate 1.

[0037] Furthermore, in order to ensure the pressing effect of the pressure head 71 on the seat plate 1, the first driving member 72 is a first cylinder, which has a first piston rod 721 that can be extended and retracted up and down, and the first piston rod 721 is connected to the pressure head 71; the threaded connection can make the longitudinal position of the pressure head 71 adjustable, and the pressure head 71 and the bottom end of the first piston rod 721 are threadedly connected and locked by an adjusting nut 73; when the pressing force is insufficient, the force of the pressure head 71 on the seat plate 1 can be adjusted by changing the threaded matching length of the first piston rod 721 and the pressure head 71 and then locking it by adjusting the nut 73.

[0038] Furthermore, in order to ensure the tensioning effect of the tensioner 93 on the stretcher 31 , the second driving member 92 is a second cylinder having a second piston rod that can be extended and retracted in the left and right directions, and the second piston rod is connected to the tensioner 93 .

[0039] Further, if Fig.10 As shown, after the flanged portion 4 of the seat cushion is flanged, the flanged portion 4 is tightly around the outer periphery of the seat plate, so the extension shape of the pull cord 31 on the outer periphery of the cover cloth 3 also matches the outer contour shape of the seat plate 1. For example, when the seat plate 1 is square, after the seat cushion is connected to the seat plate 1, the extension track of the pull cord 31 is also square, and the direction is a regular shape. When the pull cord 31 is tightened, it only needs to act on the pulling section 32 laterally. However, when the seat plate 1 is an irregular shape, after the seat cushion is connected to the seat plate 1, the extension track of the pull cord 31 on the outer periphery of the cover cloth 3 will also become an irregular shape. Specifically, if Fig.10 As shown, the shape of the outer contour of the seat cushion in this embodiment is an irregular polygon, and the pulling section 32 of the pull cord 31 is at the intersection of two oblique sides. Therefore, the outward extension direction of the pulling section 32 is not horizontal extension, but oblique extension. At this time, if the pulling section 32 is still tightened by horizontal pulling, the pulling section 32 is easy to tear the covering cloth 3 due to the different force direction from the extension direction of the pull cord 31, causing the pull cord 31 to separate from the covering cloth 3; to avoid this phenomenon, the wire pulling mechanism 9 also includes a horizontal plate 91 for installing a second driving member 92, and the horizontal plates 91 are symmetrically arranged on the left and right sides of the supporting mechanism, and the horizontal plates 91 can rotate forward and backward and stop at the corresponding position; the tightening direction of the tensioner 93 on the pull cord 31 is changed to adapt to the extension direction of the exposed part of the pull cord 3, so that the pull cord 31 will not separate from the outer periphery of the covering cloth 3 when tightened.

[0040] Furthermore, the transverse plate 91 stays in the corresponding position as follows: the transverse plate 91 rotates forward and backward along an arc-shaped trajectory, and a plurality of waist-shaped grooves 911 extending along the arc-shaped rotation trajectory are provided on the transverse plate 91, and a plurality of screw holes 122a corresponding to the positions of the waist-shaped grooves 911 are provided on the supporting mechanism. After the transverse plate 91 is rotated forward and backward into position, the corresponding screws pass through each waist-shaped groove 911 and are screwed into the screw holes 122a to lock the transverse plate 91 on the supporting mechanism, so that the transverse plate 91 rotated into position stays in the corresponding position; thereby, the tensioner 93 can act obliquely on the pulling section 32 to adapt to the extension direction of the pulling section 32. This design makes it unnecessary to worry about the pull rope 31 falling off from the edge of the cover cloth 3 when assembling the special-shaped seat plate 1 and the seat cushion.

[0041] Furthermore, in order to facilitate the adjustment of the supporting position of the seat plate 1 and the seat cushion, the supporting mechanism includes a bottom plate 12, and the upper end of the bottom plate 12 is provided with a fixed plate 121 and a distance-adjusting plate 122 spaced front and back in sequence. The distance-adjusting plate 122 can slide back and forth on the bottom plate 12 and change the distance between it and the fixed plate 121; to adapt to different front and rear widths of the seat, so that seats of different specifications and sizes can be firmly supported; specifically, a sliding mechanism is provided between the bottom plate 12 and the distance-adjusting plate 122, and the sliding mechanism includes a sliding member connected to the bottom plate The support rod 124 is slidably connected with a sliding member 125, which is connected to the distance adjusting plate 122 so that the distance adjusting plate 122 can slide forward and backward on the bottom plate 12; in order to prevent the sliding member 125 from sliding out of the sliding support rod 124, a limiting cap 123 having an outer diameter greater than the rod diameter of the sliding support rod 124 is connected to the rear end of the sliding support rod 124; the limiting cap 123 can hold the sliding member 125 when it slides to the rear end, preventing the sliding member 125 from sliding out of the sliding support rod 124. Furthermore, the sliding member 125 that has slid into place should remain fixed so that the seat plate 1 and the cushion placed on the supporting mechanism remain stable. A strip groove 12a extending forward and backward is provided on the base plate 12. A locking assembly is connected to the bottom end of the distance adjusting plate 122. The locking assembly includes a locking nut and a screw rod 12b inserted into the strip groove 12a. The bottom end of the screw rod 12b extends downward through the strip groove 12a. When the distance adjusting plate 122 can slide forward and backward on the base plate 12 to a predetermined position, the locking nut cooperates with the bottom end of the screw rod 12b and presses the base plate 12, so that the distance adjusting plate 122 stays in the predetermined position. The positioning process of the distance adjusting plate 122 is simplified to a knob process of the locking nut, and the design is simple and practical.

[0042] Furthermore, the seat forming device can be used to assemble seats of different sizes and specifications. Specifically, when the size and specifications of the seat change, it is difficult for the pressing head 71 to be aligned with the middle of the back of the seat plate 1. Therefore, a sliding seat 112 that can slide back and forth is connected to the frame 5 of the seat forming device. The sliding seat 112 is connected to the bottom end of the supporting mechanism by a supporting rod. The sliding seat 112 can slide back and forth and stop at a corresponding position so that the middle of the back of the seat plate 1 is aligned with the pressing head 71; the sliding seat 112 can change the relative position of the seat and the pressing head 71 to ensure that the back of the seat plate 1 of the seat to be formed is stably stressed and the flanging of the flanging portion 4 is uniform; so that the device can process uneven A chair seat of the same specification and size; specifically, the frame 5 is provided with a first adjusting mechanism 11 connected to the sliding seat 112, the first adjusting mechanism 11 includes a sliding support shaft 104, and an axle seat 105 supported at both ends of the sliding support shaft 104, a sliding sleeve 103 is slidably connected to the sliding support shaft, the sliding sleeve 103 is connected to the sliding seat 112, a threaded hole connected to the sliding support shaft 104 is opened on the sliding sleeve 103, and a set screw b is fitted in the threaded hole; the sliding sleeve 103 slides on the sliding support shaft 104 and is tightly pressed against the shaft body of the sliding support shaft 104 through the set screw b, so that the sliding seat 112 slides back and forth and stops at the corresponding position.

[0043] Furthermore, chair seats of different sizes have different thicknesses, so the support rod is a telescopic rod that can be raised and lowered. The telescopic rod can be raised and lowered to adjust the distance between the chair seat and the pressure head 71; the telescopic rod can change the distance between the supporting mechanism and the pressure head 71, so that the device can process chair seats of different thicknesses.

[0044] Furthermore, the telescopic rod includes a fixed rod 111, a lifting rod 111a that can be extended up and down relative to the fixed rod 111, and the lifting rod 111a and the fixed rod 111 are respectively connected to the supporting mechanism and the sliding seat 112; although the telescopic rod remains stable in the longitudinal direction, it is in a suspended state in the transverse direction. Therefore, in order to make the telescopic rod more stable, a positioning member 101 that can slide transversely is connected to the frame 5, and the positioning member 101 is connected to the fixed rod 111; when the sliding seat 112 slides back and forth into place, the positioning member 101 can slide transversely with the sliding seat 112 and stay in the corresponding position to form a transverse positioning for the telescopic rod, so as to prevent the telescopic rod from being suspended and falling over; specifically, The positioning member 5 is a plate-shaped structure in this embodiment, but its actual structure is diverse and can also be rod-shaped. A mounting frame 51 is provided on the frame 5, and a second adjustment mechanism 10 connected to the positioning member 101 is provided on the mounting frame 51. The second adjustment mechanism 10 has the same structure as the adjustment mechanism 11; it also includes components such as a sliding sleeve 103, wherein one end of the positioning member 5 is connected to the sliding sleeve 103, and the other end is screwed to the fixing rod 111 through a support plate 105, so that the positioning member 101 can slide forward and backward with the sliding seat 112; the positioning member 101 can also stay at the corresponding position according to the sliding position of the sliding seat 112, forming a stable lateral support for the telescopic rod; Furthermore, in order to facilitate the picking of materials, the frame is provided with an auxiliary material table 8 located in front of the supporting mechanism, and the auxiliary material table 8 can be used to place materials to be processed, such as seat cushions, seat boards 1, etc.; in order not to interfere with the seat placed on the supporting mechanism, the auxiliary material table 8 is provided with an avoidance area 81 for avoiding the seat cushions and seat boards 1 at one end facing the supporting mechanism.

[0045] Furthermore, a roller 53 is connected to the bottom end of the frame 5, and the design of the roller 53 is convenient for carrying and moving the seat forming device to a processing position.

[0046] like Figure 6-9 As shown, an application of the chair seat forming device is further provided, comprising the following steps: S1: Place the seat cushion and the seat plate 1 with the pull rope 31 connected to the outer periphery on the supporting mechanism in sequence, so that the seat cushion forms a flange portion 4 that exceeds the outer contour of the seat plate 1, and the seat plate 1 faces the pressure head 71 above; to ensure that the pressure head 71 exerts a uniform force on the seat plate 1, the pressure head 71 needs to face the middle position of the seat plate 1; S2: The first driving member 72 drives the pressing head 71 to move downward and act on the seat plate 1 to deform the seat cushion, and causes the flanged portion 4 of the seat cushion to be flanged toward the inner side of the seat plate 1; in this embodiment, since the positioning portions 41 on both sides of the flanged portion 4 have been attached to the inner side of the seat plate 1, it is the side connecting portion 42 that is flanged toward the inner side of the seat plate 1 in this step; if there is no positioning portion 41, the entire flanged portion 4 is flanged toward the inner side of the seat plate 1; S3: Connect the two ends of the pull rope 31 on the flange part 4 to the tensioner 93, and drive the tensioner 93 to move in the left and right directions through the corresponding second driving member 92 and tighten the pull rope 31, so that the flange part 4 is tightened on the inner side of the seat plate 1; similarly, in this embodiment, it is the side connecting part 42 that is tightened and fits on the inner side of the back side of the seat plate 1; if there is no positioning part 41, the entire flange part 4 is tightened on the inner side of the seat plate 1; it is not difficult to see that when the seat forming equipment is used, the molding process of the seat is simplified into a simple seat placement process and a connection process of the pull rope 31. The worker only needs to place the seat plate 1 and the cushion on the supporting mechanism. After the flange part 4 is flanged, the two pulling sections 32 of the pull rope 31 are first connected to the tensioner 93 for tightening. The operation is simple and labor-saving, which reduces the operational difficulty of seat molding and improves the molding efficiency of the seat.

[0047] Further, if Fig. 9 As shown, in order to prevent the drawstring 31 from loosening after tightening, the pulling section 32 needs to be tightened. Therefore, after step S3, the pulling sections 32 of the two tightened drawstrings 31 are still attached to the flange portion 4 and fixed to the seat plate 1 through the nails 4a; then the excess exposed drawing section 31 can be cut off; the fixed drawing section 32 can keep the drawstring 31 in a tightened state at all times to prevent the seat cushion and the seat plate 1 from loosening.

[0048] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
