Description

Technical Field

[0001] This invention belongs to the technical field of mattress processing equipment, and in particular relates to a wainscoting cutting and splicing equipment. Background Technology

[0002] A mattress is an item placed between the human body and a bed to ensure consumers get healthy and comfortable sleep. Mattresses are made of a variety of materials, and mattresses made of different materials can provide different sleep effects. Near the end of production, strips are sewn around the outer edge of the mattress.

[0003] Since the trim strips, after being sewn with handles, trademarks, and hang tags, need to be sewn onto the mattress to stabilize it, and since the trim strips are a single piece after being processed on the assembly line, they need to be cut to a sufficient length before sewing them onto the mattress. Then, the cut trim strips need to be spliced ​​together end to end.

[0004] As for the existing sewing of the tarpaulin that has undergone a series of processing steps, most of the time, operators use semi-automatic mechanical equipment to first cut the rolled-up tarpaulin to the same length, and then use a sewing machine to sew the cut tarpaulin together end to end. Obviously, this method not only consumes a lot of manpower and resources, but also reduces the efficiency of cutting and splicing the tarpaulin. This method is also difficult to integrate with the tarpaulin processing assembly line to achieve fast, efficient and integrated processing of the tarpaulin. Summary of the Invention

[0016] The present invention has the following beneficial effects:

[0017] 1. This invention, through the coordinated arrangement of a tensioning guide mechanism, a pressing and cutting mechanism, a welt correction mechanism, a flipping and overlapping mechanism, and a left-right horizontal sliding clamping and transfer mechanism on a cutting platform from front to back, allows the free end of the welt entering the cutting platform to be first conveyed to the outside of the flipping and overlapping mechanism via the tensioning guide mechanism. The welt correction mechanism corrects the conveyed welt to prevent it from tilting. The flipping and overlapping mechanism clamps the free end of the welt and flips it face down, then overlaps it onto the surface of a sufficiently long welt. At this point, the pressing and cutting mechanism presses and cuts the overlapped and aligned welt. Finally, the clamping and transfer mechanism clamps and transfers it to the sewing machine for splicing. This facilitates the cutting and splicing of welts after a series of processing steps on an assembly line, improving the efficiency of the welt assembly line processing and reducing the cost of welt processing.

[0018] 2. This invention utilizes the cooperation of a flipping and overlapping mechanism and a pressing and cutting mechanism. The cooperation of the support clamp and sliding clamp of the flipping and overlapping mechanism can clamp and fix the free end of the welt that extends a short distance. Then, driven by a rotary cylinder, the clamped welt is flipped face down. Under the drive of the transmission screw, the clamped and flipped welt is slid and driven to the pressing and cutting mechanism to align the free end of the welt with the welt on the upper surface of the cutting platform. At this time, the adjustment correction strip can play an alignment and correction role for the welt being aligned, thereby facilitating the pressing and cutting mechanism to press and cut the aligned welt quickly, thus further improving the accuracy and efficiency of the welt flipping, cutting and splicing.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-9As shown, this invention is a welt cutting and splicing device, including a platform box 1. A cutting platform 2 is fixedly supported on the upper surface of the platform box 1. A tensioning guide mechanism 3 is installed on the cutting platform 2. A pressing cutting mechanism 4 is installed behind the tensioning guide mechanism 3. The pressing cutting mechanism 4 is used to cut the welt after sewing, which is guided and conveyed by the tensioning guide mechanism 3. A welt correction mechanism 5 is installed behind the pressing cutting mechanism 4, and a flipping and overlapping mechanism 6 is installed behind the welt correction mechanism 5. The clamping and aligning mechanism 9 is used to clamp and align the edges of the sash conveyed to the rear of the cutting platform 2. The clamping and aligning mechanism 6 and the sash alignment mechanism 5 are horizontally slidably installed between them. The clamping and aligning mechanism 9 is used to clamp and cut the sash after alignment, and then convey it to the sewing machine 30 on the right side of the cutting platform 2. The sewing plate 301 of the sewing machine 30 is provided with a pressing and sliding mechanism 10. The pressing and sliding mechanism 10 is used to press and slide the sash that has been clamped and transferred to the sewing plate 301 so that the sewing machine 30 can sew the sash.

[0045] In the design scheme of this invention, the platform box 1 and operating platform of the cutting and splicing equipment of this invention are set at the end of the welt production line. When the welt with trademarks, hang tags and handles is sewn on, it enters the conveying end of the cutting platform 2. At this time, the tensioning guide mechanism 3 will continuously convey the welt to the rear of the cutting platform 2. When the free end of the welt passes through the pressing cutting mechanism 4 and the welt correction mechanism 5 and enters the flipping and stacking mechanism 6, the flipping and stacking mechanism 6 will clamp and fix the free end of the welt, and make the free end of the welt protrude a small section. When the welt is continuously conveyed to the rear of the cutting platform 2 and reaches the length to be cut, the control system will control the flipping and stacking mechanism 6 to first flip the back of the welt, and then move the free end of the welt to the pressing cutting mechanism 4. At this time, the pressing cutting mechanism 4 will press the free end of the welt to the upper surface of the uncut welt. At the same time, the clamping and transfer mechanism 9 will first move to the upper and lower stacking mechanism. At the aligned section of the webbing, the back of the overlapping webbing to be cut is clamped and fixed. Then, the pressing and cutting mechanism 4 cuts the overlapping webbing on the cutting platform 2. After the webbing is cut, the pressing and cutting mechanism 4 and the flipping and overlapping mechanism 6 simultaneously disengage from the clamping and pressing of the cut webbing. Then, the clamping and transferring mechanism 9 clamps and transfers the overlapping and cut webbing to the head of the sewing machine 30. Then, the pressing and sliding mechanism 10 moves the overlapping and aligned webbing... The strip is pressed onto the sewing plate 301. At this time, the clamping and transfer mechanism 9 disengages from the gripping strip, and the pressing and sliding mechanism 10 drives the overlapping strip to run on the sewing plate 301 of the sewing machine 30. This facilitates the sewing machine 30 to splice the overlapping and aligned strip end to end, thus enabling the strips after a series of processing steps to be cut and spliced ​​on the assembly line. This not only improves the efficiency of the strip assembly line processing but also reduces the cost of strip processing.

[0046] In one embodiment of the present invention, the tensioning guide mechanism 3 includes a side plate 31, a bearing seat 32, a drive roller 33, a sliding sleeve 34, a driven shaft 35, a driven roller 36, a connecting horizontal plate 37, and a tensioning cylinder 38. Two side plates 31 are vertically symmetrically fixed to the left and right sides of the cutting platform 2, and a servo motor is fixed to the outer ring surface of one of the side plates 31. Bearing seats 32 are fixed to the symmetrical sides of both side plates 31, and a drive roller 33 is rotatably mounted between the two bearing seats 32 via a bearing. One end face of the drive roller 33 is connected to the output shaft of the servo motor, and the upper outer ring surface of the drive roller 33 is flush with the cutting platform 2. The upper surface of the upright plate 31 is vertically provided with a sliding guide groove 311, and a sliding sleeve 34 is slidably provided in each sliding guide groove 311. The outer ring surface of the sliding sleeve 34 is vertically provided with a limiting groove 341, and the limiting groove 341 is slidably engaged with the two side walls of the sliding guide groove 311. A driven shaft 35 is rotatably installed between two symmetrical sliding sleeves 34 through a bearing, and two driven rollers 36 are symmetrically fixed on the driven shaft 35. A connecting horizontal plate 37 is fixed on the upper surface of the symmetrical side upright plate 31, and a tensioning cylinder 38 is symmetrically fixed on the upper surface of the connecting horizontal plate 37. The lower end face of the piston rod of the two tensioning cylinders 38 passes through the connecting horizontal plate 37 and connects with the sliding sleeve 34.

[0047] In the design of this invention, the piston rods of the symmetrical tension cylinders 38 extend and retract synchronously, causing them to push the sliding sleeve 34 to slide up and down in the sliding guide groove 311 vertically opened above the side plate 31. This enables the driven rollers 36, which are symmetrically fixed on the driven shaft 35, to adjust upward or downward directly above the drive roller 33. The output shaft of the servo motor fixed on the outer side of the side plate 31 operates, causing it to drive the drive roller 33 to rotate. Thus, the cooperation between the drive roller 33 and the driven roller 36, which can be adjusted upward and downward, can continuously transport the sheath to the rear of the cutting platform 2.

[0048] In one embodiment of the present invention, the pressing and cutting mechanism 4 includes a support block 41, a pressing cylinder 42, a connecting block 43, a pressing plate 44, a cutting disc 45, a supporting ear plate 46, a pulley 47, a transmission belt 48, a guide plate, a rodless cylinder 491, and a limiting plate 492. Support blocks 41 are symmetrically fixed to the upper surface of the connecting horizontal plate 37, and a pressing cylinder 42 is vertically fixed to each of the two support blocks 41. The piston rod ends of the two pressing cylinders 42 pass through the support blocks 41 and are respectively fixedly connected to the connecting blocks 43. Two pressing plates 44 are symmetrically fixed between the two connecting blocks 43, and a cavity 441 is formed between the two pressing plates 44. Cutting grooves 21 are horizontally opened on the upper surface of the cutting platform 2, and the cutting grooves 21 are aligned with the cavity 441. A cutting disc 45 is slidably installed in the cutting grooves 21. The outer ring surface of the cutting disc 45... The height is higher than the cutting platform 2, and the cutting disc is rotatably mounted on the support ear plate 46 via a rotating shaft. The support ear plate 46 is vertically positioned below the cutting platform 2. The rotating shaft extends out of the front side of the support ear plate 46 and is fixedly sleeved with a pulley 47. The lower front side of the support ear plate 46 is fixedly supported by a support column, and a pulley 47 is also fixedly sleeved on the output shaft of the servo motor. The two pulleys 47 are connected by a transmission belt 48. The support ear plate 46 is slidably mounted on the frame of the platform box 1 via a guide sliding assembly. The guide connecting plate is horizontally fixed on the frame, and a rodless cylinder 491 is fixed on the front side of the guide connecting plate along its length. The slider of the rodless cylinder 491 is fixedly connected to the rear side of the support ear plate 46. Two symmetrical limit plates 492 are fixedly mounted on the frame connecting the left and right end faces of the guide connecting plate.

[0049] In the design scheme of this invention, after the flipping and overlapping mechanism 6 clamps and flips the end of the webbing input to the back of the cutting platform 2, the tensioning guide mechanism 3 continuously transports the webbing to the back of the cutting platform 2. When the transported webbing reaches the length required for cutting and splicing, the flipping and overlapping mechanism 6 sends the free end of the webbing into the lower part of the pressing and cutting mechanism 4. Then, it controls the piston rod of the symmetrical pressing cylinder 42 to extend, so that it drives the two symmetrical pressing plates 44 to descend and press against the upper surface of the overlapping webbing through the two connecting blocks 43. At this time, the cavity 441 formed between the two pressing plates 44 is aligned with the cutting groove 21 on the cutting platform 2, and the free end of the overlapping webbing is also located at the cavity 441 and the cutting groove 21. Then, the servo motor on the outer side of the supporting ear plate 46 is started, so that its output shaft passes through the pulley 47 and The transmission belt 48 controls the rotation of the cutting disc 45, which extends slightly out of the cutting groove 21. Then, it controls the rodless cylinder 491 to work, causing the rotating cutting disc 45 to slide horizontally left and right within the cutting groove 21 via the support ear plate 46. This allows the overlapping welt, which is pressed by the pressing plate 44, to be cut. After the overlapping welt is cut, the clamping and transfer mechanism 9 slides between the pressing and cutting mechanism 4 and the flipping and overlapping mechanism 6 to clamp and fix the cut welt. At this time, the piston rods of the two pressing plates 44 press the cylinder 42 to retract and slide upward. Simultaneously, the flipping and overlapping mechanism 6 disengages from the welt, and the clamping and transfer mechanism 9 clamps and transfers the cut welt to the sewing machine head 30. Then, through the driving and sliding of the pressing and sliding mechanism 10, the overlapping and cut welt is spliced.

[0050] In one embodiment of the present invention, the welt correction mechanism 5 includes a mounting block 51, a double-rotating screw 52, ​​a limiting block 53, a nut seat 54, a connecting ear plate 55, a correction cylinder 56, and a correction strip 57. Two mounting blocks 51 are symmetrically fixed to the lower side of the cutting platform 2, and a double-rotating screw 52 is rotatably mounted between the two mounting blocks 51 via a bearing. The middle part of the double-rotating screw 52 is rotatably connected to the lower side of the cutting platform 2 via a limiting block 53, and a nut seat 54 is symmetrically sleeved on the double-rotating screw 52. A connecting ear plate 55 is fixed to the outer side of each nut seat 54, and a correction cylinder 56 is vertically fixed to the outer side of the connecting ear plate 55. Correction strips 57 are fixed to the upper surface of the piston rods of the symmetrical correction cylinders 56. Correction grooves 22 are symmetrically opened on the upper surface of the cutting platform 2, and correction strips 57 slide out of the symmetrical correction grooves 22.

[0051] In the design of this invention, when the webbing is conveyed to the rear of the cutting platform 2 via the tensioning guide mechanism 3, the operation of the servo motor connected to one end of the double-rotating screw 52 can be controlled according to the width of the conveyed webbing. This causes the servo motor to drive the connecting ear plates 55 to slide closer or further apart through the double-rotating screw 52 and the nut seat 54. Consequently, the connecting ear plates 55 will drive the symmetrical correction strips 57 to slide closer or further apart within the correction groove 22 via the symmetrical correction cylinders 56. When the symmetrical correction strips 57 slide to almost reach the left and right sides of the webbing, the correction is then performed. The piston rod of cylinder 56 extends, causing it to drive the correction strip 57 to extend from the correction groove 22 and above the upper surface of the cutting platform 2. Then, the double-rotating screw 52 is controlled to rotate slowly, causing it to drive the extended correction strip 57 to fit against the left and right sides of the webbing. This facilitates the correction of the continuously conveyed webbing and prevents the webbing from tilting when it is conveyed on the cutting board. This would affect the accuracy of the flipping and stacking mechanism 6 in aligning the free end of the webbing held with the webbing below the pressing and cutting mechanism 4, and thus affect the aesthetics and quality of the webbing splicing after cutting.

[0052] In one embodiment of the present invention, the flipping and stacking mechanism 6 includes vertical square rods 61, a square cover 62, a transmission screw 63, suspension lugs 65, side lugs 66, an irregular support plate 67, and a clamping and flipping assembly 7. Two vertical square rods 61 are vertically fixed to the left side of the cutting platform 2, and square covers 62 are horizontally fixed to the front and rear ends of the two vertical square rods 61. A transmission screw 63 is rotatably mounted inside the square cover 62 via bearings, and a servo drive is fixed to the end of the square cover 62. The output shaft of the motor is connected, and a screw nut is sleeved on the transmission screw 63. A suspension ear 65 is fixedly installed on the screw nut. The suspension ear 65 extends downward into the notch groove of the square cover 62, and a side ear plate 66 is fixedly connected to the outer side of the suspension ear 65. A special-shaped support plate 67 is fixed to the inner side of the side ear plate 66. A clamping and flipping assembly 7 is installed on the frontmost side of the special-shaped support plate 67. The clamping and flipping assembly 7 is used to clamp and flip the opposite side of the strip output by the cutting platform 2.

[0053] In the design of this invention, when the cut and stacked webbing is transferred to the sewing area for sewing and splicing via the clamping and transfer mechanism 9, the webbing on the cutting platform 2 will continue to be output backward. When the free end of the continued-feeding webbing extends a short distance beyond the clamping and flipping assembly 7, the clamping and flipping assembly 7 will clamp and fix the extended webbing, and simultaneously flip the clamped webbing face down. Then, the fixed servo motor on the rear side of the square cover 62 is controlled to work, causing it to drive the suspension ear 65 to slide forward along the square cover 62 via the transmission screw 63 and screw nut. Subsequently, the suspension ear 65 will drive the webbing clamped by the clamping and flipping assembly 7 to slide a short distance away from the side of the cutting platform 2 via the side ear plate 66 and the irregular support plate. At this time, the continuously fed webbing will fall into the conveying platform below the outer side of the cutting platform 2. When the webbing is fed to a size sufficient for cutting and splicing, the transmission screw 63 will then... 3. Reverse rotation will drive the clamping and flipping assembly 7 through the irregular support plate to move the free end of the clamped and flipped strip towards the pressing and cutting mechanism 4. At this time, the clamping and flipping assembly 7 will continuously adjust the height and placement angle of the free end of the strip so that the free end of the strip can be accurately attached to the upper surface of the strip in the cutting area and aligned with the cutting groove 21 and the cavity 441. This facilitates the pressing plate 44 to press and overlap the free end of the strip onto the upper surface of the strip. Then, the sliding of the rotating cutting disc 45 can quickly and accurately cut the pressed and overlapped strip. After the strip is cut, the clamping and transferring mechanism 9 will clamp and fix the aligned parts of the overlapping cut strip. At this time, the clamping and flipping assembly 7 will disengage from the cut strip. Then, the transmission screw 63 will rotate, which can drive the clamping and flipping assembly 7 to slide back to the initial state, which is convenient for clamping and flipping the strips that are still being transported by the cutting platform 2.

[0054] In one embodiment of the present invention, the clamping and flipping assembly 7 includes a lowering cylinder 71, a vertical sliding plate 72, a rotating cylinder 73, a vertical connecting plate 74, a support clamping plate, a side connecting plate 76, a vertical clamping cylinder 77, a sliding clamping plate 78, a pin insertion cylinder 79, and a pin insertion rod 791. The uppermost front surface of the irregular support plate 67 is vertically fixed with the lowering cylinder 71, and the piston rod end face of the lowering cylinder 71 is connected to the vertical sliding plate 72. The outer side of the vertical sliding plate 72 is fixed with the rotating cylinder 73. The upper side of the vertical connecting plate 74 is connected to the output end of the rotating cylinder 73, and the other side of the upper end of the vertical connecting plate 74 is horizontally fixed with supports. The clamping plate has a side connecting plate 76 horizontally fixed to the other side of the lower end of the vertical connecting plate 74, and a vertical clamping cylinder 77 vertically fixed to the inner side of the side connecting plate 76. A sliding clamping plate 78 is horizontally fixed to the upper end face of the piston rod of the vertical clamping cylinder 77, and the sliding clamping plate 78 is aligned vertically with the support clamping plate. The sliding clamping plate 78 and the support clamping plate are symmetrically provided with insertion grooves 781 along their length direction. A pin insertion cylinder 79 is vertically symmetrically fixed to the lower surface of the sliding clamping plate 78, and a pin insertion rod 791 is fixed to the upper end face of the piston rod of the pin insertion cylinder 79. The two symmetrical pin insertion rods 791 are slidably inserted into the insertion grooves 781.

[0055] In the design of this invention, when the webbing extends a short distance beyond the outer side of the open support clamp and sliding clamp 78, the control system controls the piston rod of the vertical clamping cylinder 77 to extend, causing it to move the sliding clamp 78 closer to the support clamp. This facilitates the sliding clamp 78 and the support clamp to clamp and fix the free end of the webbing. At this time, the piston rod of the pin insertion cylinder 79 extends, causing it to drive the pin insertion rod 791 through the insertion groove 781 on the sliding clamp 78 and insert it into the webbing. The needle of 791 will enter the insertion groove 781 opened in the support clamp plate to prevent the strip from falling out from between the clamping sliding clamp plate 78 and the support clamp plate. Then, the rotary cylinder 73 is controlled to work, so that its output shaft drives the sliding clamp plate 78 and the support clamp plate to rotate 180° counterclockwise through the vertical connecting plate 74, so that the clamped strip flips to face down. Then, the transmission screw 63 rotates, which drives the strip held by the sliding clamp plate 78 and the support clamp plate to move a small distance away from the side of the cutting platform 2 through the irregular support plate. The continuously conveyed webbing falls into the conveyor platform below the outer side of the cutting platform 2. When the webbing output is large enough for cutting and splicing, the irregular support plate drives the rotating sliding clamp 78 and the webbing held by the support clamp to slide towards the pressing cutting mechanism 4. Then, the piston rod of the lowering cylinder 71 is extended, causing it to drive the webbing held by the support clamp and sliding clamp 78 to descend and fit against the webbing on the upper surface of the cutting platform 2 via the vertical slide plate 72. Then, the pressing cutting mechanism 4 cuts the overlapping and aligned webbing. After the welt is cut, the clamping and transfer mechanism 9 clamps and fixes the cut welt. At this time, the piston rods of the vertical clamping cylinder 77 and the insertion cylinder retract synchronously, causing the sliding clamping plate 78 and the insertion pin rod 791 to disengage from the clamping and insertion of the welt, thus facilitating the clamping and transfer mechanism 9 to clamp and transfer the cut welt. Then, the output end of the rotary cylinder 73 rotates, rotating the sliding clamping plate 78 and the support clamping plate back to their initial state, thus facilitating the flipping, alignment and stacking of the conveyed welt again.

[0056] In one embodiment of the present invention, the flipping and stacking mechanism 6 further includes a strip lifting assembly 8. The strip lifting assembly 8 includes a hinge cylinder 81, a toggle bar 82, a hinge column 83, a swing support bar 84, and a lifting column 85. The hinge cylinder 81 is installed on the outer side of the rear vertical square rod 61 with its tilt facing upward. The piston rod end of the hinge cylinder 81 is hinged to the toggle bar 82. The other end of the toggle bar 82 is connected to the swing support bar 84. The toggle bar 82 and the swing support bar 84 are integrally formed at an obtuse angle. The length of the toggle bar 82 is less than the length of the swing support bar 84. The connection between the toggle bar 82 and the swing support bar 84 is hinged to the outer side of the rear vertical square rod 61 through the hinge column 83. The swing support bar 84 is horizontally installed on the left and right sides of its tilting downward bottom end. The lifting column 85 is located on the outside of the clamping and flipping assembly 7.

[0057] In the design of this invention, when the clamped strip is continuously output, the lifting column 85 will be located below the output strip. When the free end of the clamped and flipped strip moves closer to the pressing and cutting mechanism 4, the piston rod of the control hinge cylinder 81 will retract, causing it to drive the lowest end of the swing support 84 to swing upward through the actuating bar 82 and the hinge column 83. This allows the actuating column to swing upward in an arc shape, lifting the overlapping strips near the side of the cutting platform 2, thereby facilitating the clamping and transfer mechanism 9 to clamp and transfer the overlapping and cut strips.

[0058] In one embodiment of the present invention, the clamping and transfer mechanism 9 includes a gear and rack transmission component 91, a sliding plate 92, a special-shaped ear plate 93, an outer clamping cylinder 94, an outer clamping block 95, a first clamping strip 96, an inner clamping cylinder 97, an inner clamping block 98, and a second clamping strip 99. The gear and rack transmission component 91 is fixedly mounted on the upper surface of the portal frame fixed to the rearmost upper surface of the platform box 1. A servo motor is fixed to the upper surface of the sliding plate 92, and the output shaft of the servo motor passes through the lower surface of the sliding plate 92 and a gear is fixed thereon. A special-shaped ear plate is vertically fixed to the side of the sliding plate 92. The irregular ear plate 93 has an outer clamping cylinder 94 vertically fixed to its lower outer side, and an outer clamping block 95 fixed to the lower surface of the piston rod of the outer clamping cylinder 94. A first clamping strip 96 is horizontally installed on the inner side of the outer clamping block 95. An inner clamping cylinder 97 is vertically fixed to its lower inner side, and an inner clamping block 98 is fixed to the lower surface of the piston rod of the inner clamping cylinder 97. A second clamping strip 99 is horizontally installed on the inner side of the inner clamping block 98, and the second clamping strip 99 is vertically aligned with the first clamping strip 96.

[0059] In the design of this invention, after the flipping and stacking mechanism 6 clamps and flips the free end of the webbing onto the upper surface of the webbing below the pressing and cutting mechanism 4, the pressing and cutting mechanism 4 cuts the stacked and aligned webbing. At this time, the servo motor on the upper surface of the sliding plate 92 is controlled to work, so that its output shaft drives the sliding plate 92 and the special-shaped ear plate 93 through the meshing of the gear and rack transmission component 91 to drive the first clamping strip 96 and the second clamping strip 99 to move towards the direction of the stacked double-layered webbing, so that the first clamping strip 96 and the second clamping strip 99 are respectively located on the upper and lower sides of the stacked webbing. Then, the piston rod of the outer clamping cylinder 94 is controlled to retract and the piston rod of the inner clamping cylinder 97 is controlled to extend. Then, the outer clamping block 95 drives the first clamping strip 96 and the inner clamping block 98 to drive the second clamping strip 99 to move closer to each other, so that the first clamping strip 96 and the second clamping strip 99 can clamp and fix the stacked and cut webbing. Then, the output shaft of the servo motor fixed on the upper surface of the sliding plate 92 is controlled to rotate in the opposite direction, so that it drives the first clamping strip 96 and the second clamping strip 99 to slide towards the head of the sewing machine 30 through the gear and rack transmission component 91. When the clamped and slidable strip moves to the pressing and sliding mechanism 10 set at the head of the sewing machine 30, the cooperation of the clamping transfer mechanism 9 and the pressing and sliding mechanism 10 can continuously drive the two aligned ends of the overlapping strip to slide back and forth at the sewing plate 301 of the sewing machine 30, which facilitates the sewing splicing of the cut part of the strip. After the strip is spliced, the outer clamping cylinder 94 and the inner clamping cylinder 97 work synchronously, so that the first clamping strip 96 and the second clamping strip 99 move away from each other, which facilitates the spliced ​​strip to fall into the conveying platform below the outer side of the cutting platform 2, so that the operator can transfer the spliced ​​strip to the next process for further processing.

[0060] In one embodiment of the present invention, the pressing and sliding mechanism 10 includes a guide rail side plate 101, a guide rail assembly, a cylinder seat 103, a sliding pressure plate 104, a pressing cylinder 105, a front and rear connecting plate 106, a supporting pressure plate, a transmission rod 108, a driving pulley 109, a driven pulley 110, and a conveyor belt 111. The guide rail side plate 101 is vertically fixed to the upper surface of the cutting platform 2. The guide rail side plate 101 is located behind the head of the sewing machine 30. The front side of the guide rail side plate 101 is vertically... A guide rail assembly is fixed, and a cylinder seat 103 is horizontally fixed to the front side of the guide rail side plate 101. A sliding pressure plate 104 is fixed to the outer side of the slider of the guide rail assembly, and the sliding pressure plate 104 slides horizontally to the rear side of the sewing needle of the machine head. A pressing cylinder 105 is vertically fixed on the cylinder seat 103, and the piston rod of the pressing cylinder 105 is connected to the outer side of the sliding pressure plate 104. A supporting pressure plate is fixedly connected to the front side of the sliding pressure plate 104 through a front and rear connecting plate 106. The support plate is located in front of the sewing needle at the machine head. A transmission rod 108 is rotatably mounted between the sliding plate 104 and the support plate, and a drive pulley 109 is symmetrically sleeved on the transmission rod 108. At least two sets of driven pulleys 110 are rotatably mounted on the bottom sides of the corresponding sides of the sliding plate 104 and the support plate via a rotating column. The drive pulleys 109 and driven pulleys 110 mounted on the sliding plate 104 and the support plate are respectively connected by a conveyor belt 111. 11 The sliding pressure plate 104 and the supporting pressure plate are arranged in a triangular shape on the corresponding sides. The lower surfaces of the two symmetrical conveyor belts 111 extend out of the lower surfaces of the sliding pressure plate 104 and the supporting pressure plate, and the two conveyor belts 111 are located on both sides of the sewing needle. The sewing plate 301 of the sewing machine 30 is also symmetrically provided with two sets of conveyor belts 111, and the two sets of conveyor belts 111 are located on both sides of the sewing needle. The two sets of symmetrical conveyor belts 111 are arranged in a trapezoidal structure at the sewing machine 30.

[0061] In the design of this invention, when the clamping and transfer mechanism 9 conveys the clamped welt toward the surface of the sewing plate 301 of the sewing machine 30, and when the stacked welt moves directly below the sliding pressure plate 104 and the supporting pressure plate, the servo motors on the rear side of the sliding pressure plate 104 and the servo motor below the sewing machine 30 are first activated, causing the two sets of conveyor belts 111 mounted on the corresponding sides of the sliding pressure plate 104 and the supporting pressure plate to rotate. Simultaneously, the two sets of trapezoidal conveyor belts 111 on the sewing plate 301 rotate synchronously. Then, the piston rod of the pressing cylinder 105 is extended, pushing the sliding pressure plate 104 downwards. The guide rail assembly guides the pressing sliding pressure plate 104, ensuring that the two sets of triangular conveyor belts 111 between the sliding pressure plate 104 and the supporting pressure plate contact the upper surface of the free end of the stacked welt. This ensures that the two sets of conveyor belts 111 on the sewing plate 301 and the two sets of conveyor belts 111 between the supporting pressure plate and the sliding pressure plate 104 rotate synchronously. The rotation of the conveyor belt 111 compresses the overlapping welts and transports them to the sewing needle of the sewing machine 30 for sewing. The clamping of the welts by the first clamping strip 96 and the second clamping strip 99 does not interfere with the sliding movement of the two sets of compressed conveyor belts 111, thus improving the sewing splicing of the welts by the sewing machine 30. Furthermore, the two sets of conveyor belts 111 are symmetrically arranged on both sides of the sewing needle of the sewing machine 30, therefore, they do not interfere with the sewing of the overlapping ends of the welts by the sewing needle. Processing; After the welt is spliced, the piston rod of the control cylinder 105 retracts, causing it to drive the two sets of symmetrical conveyor belts 111 upward through the sliding pressure plate 104 and the support pressure plate to disengage from the spliced ​​welt. Then, the first clamping strip 96 and the second clamping strip 99 disengage from the spliced ​​welt, allowing the spliced ​​welt to fall into the conveyor platform below the outer side of the cutting platform 2, making it easier for the operator to transfer the spliced ​​welt to the next process for further processing.

[0062] In one embodiment of the present invention, a punching mechanism 20 is provided at the input port of the cutting platform 2. The punching mechanism 20 includes a portal frame 201, a punching cylinder 202, a punching block 203, a punching rod 204, a punching head 205, a support spring 206, a pressing sleeve 207, an L-shaped ear plate 208, a sliding guide rod 209, a guide sleeve 210, and a punching protective plate.

[0063] In the design of this invention, when it is necessary to punch holes in the strip entering the cutting platform 2, when the position of the strip to be punched moves to directly below the punching head 205, the piston rod of the punching cylinder 202 is extended, causing it to drive the punching head 205 down to the surface of the strip through the punching block 203 and the punching rod 204. At this time, the clamping sleeve 207 will first contact the surface of the strip, and as the punching rod 204 descends, the clamping sleeve 207 will slide upward along the punching rod 204. At this time, the support spring 206 will be compressed, and then the punching head 205 will... 5 will punch holes in the sash, and the material drop hole of the protective plate on the cutting platform 2 will be protected by the punch head 205. At the same time, when the punch block 203 descends, it will drive the sliding guide rod 209 to descend in the guide sleeve 210 through the L-shaped ear plate 208. After the sash is punched, the piston rod of the punch cylinder 202 retracts, causing the punch head 205 to disengage from the sash and rise. The pressing sleeve 207 will be pressed down by the elastic thrust of the support spring 206 and connected to the punch head 205, so that the punched sash can continue to be conveyed backward for cutting and splicing.
