Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, and in particular to a two-stage buffer elastic pressing mechanism and a garment bag opening machine. Background Technology

[0002] Pocket opening machines are one of the core pieces of equipment in automated garment pocket opening processing, and the clamping stability of their frame pressing mechanism directly determines the processing accuracy of the pocket opening. Currently, most mainstream pocket opening machines on the market adopt a "single-press" design for their frame pressing mechanism, meaning that a single drive unit drives the frame pressing assembly to complete the clamping action on the large cut piece in one go. However, this type of design has obvious drawbacks: to adapt to fabrics of different thicknesses or pocket openings of different sizes, the frame pressing mechanism needs to allow for a long descent stroke, resulting in a large amount of motion inertia during the rapid pressing process. When the frame pressing assembly contacts the large cut piece, the inertial impact can easily cause fabric displacement, wrinkles, or local deformation, which not only affects the trajectory accuracy of laser-cut pocket opening (such as pocket opening size deviation and rough edges), but also leads to irregular folding and sewing stitch deviation in the subsequent process, ultimately reducing the processing quality and pass rate of garment pocket openings.

[0003] In addition, the clamping components of traditional pressing mechanisms are mostly rigid structures, which cannot adaptively adjust the clamping force according to the elastic characteristics of the fabric. This can easily cause excessive compression damage to thin and easily stretched fabrics, while for thick fabrics, insufficient clamping force may cause the fabric to loosen during processing, thus failing to meet the processing needs of different types of fabrics. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a two-stage buffer elastic pressing mechanism and a garment bag opening machine, which has the advantages of improving pressing accuracy and meeting the processing needs of different types of fabrics.

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution: The first aspect of the present invention discloses a two-stage buffer elastic pressing mechanism, comprising: Fixed base; A pressing base is slidably mounted on the fixed base in the vertical direction. A pressing assembly for pressing the cut pieces is installed on the pressing base. A pressing drive component for driving the pressing base to move up and down is provided on the fixed base. The limiting buffer member fixed to the pressing base; and, A buffer cylinder supported on the fixed base is used to support the limiting buffer member. The piston rod of the buffer cylinder is in an extended state when the pressing drive member drives the pressing base to descend, so as to support the limiting buffer member to counteract the motion inertia of the pressing assembly. After buffering is completed, it retracts to eliminate the restriction on the limiting buffer member, so that the pressing assembly presses the cut piece.

[0006] To achieve the above technical solution, in the initial state, the pressing base is in a high position and the piston rod of the buffer cylinder is in a retracted state. During the bag opening process, the piston rod of the buffer cylinder extends, and the pressing drive drives the pressing base to descend until the piston rod of the buffer cylinder contacts the limiting buffer, thus pressing down to buffer and offset the motion inertia of the pressing assembly. At this time, there is a slight gap between the pressing assembly and the cut piece. Then, the piston rod of the buffer cylinder retracts, and the pressing drive continues to drive the pressing base to descend. At this time, the pressing assembly presses down on the surface of the cut piece, completing the pressing process. Because the buffer cylinder and the limiting buffer work together to buffer the motion inertia of the pressing assembly during the pressing process, the pressing assembly is prevented from directly impacting the cut piece, effectively preventing the fabric from shifting, wrinkling, or deforming, ensuring positioning accuracy, and the pressing stability is higher because the inertia is controlled.

[0007] In one embodiment of the present invention, a positioning piece is provided on the fixed base between the limiting buffer and the buffer cylinder. When the limiting buffer abuts against the positioning piece, the pressing assembly presses the cut piece.

[0008] The above technical solution achieves precise limiting of the descent limit position of the pressing component by using a positioning piece to abut against the limiting buffer, thereby effectively improving the pressing accuracy.

[0009] In one embodiment of the present invention, the positioning plate is provided with an opening for the piston rod of the buffer cylinder to extend out.

[0010] To achieve the above technical solution, the positioning piece is fixed on the base and does not move with the piston rod of the buffer cylinder. Instead, the piston rod is held in a supporting state by the limiting buffer component through the through-hole, thus more precisely defining the buffer position. When the piston rod of the buffer cylinder retracts, the limiting buffer component and the positioning piece can still maintain the limiting state. When the buffer rod of the limiting buffer component retracts, the pressing assembly presses the cut piece.

[0011] In one embodiment of the present invention, the limiting buffer is a limiting cylinder disposed opposite to the buffer cylinder, and the piston rod of the limiting cylinder is in an extended state to abut against the piston rod of the buffer cylinder.

[0012] To achieve the above technical solution, a limiting cylinder is used as a limiting buffer component. The air pressure inside the cylinder can be used for further buffering, effectively improving the buffering effect. Furthermore, the buffering distance can be adaptively adjusted by controlling the extension distance of the piston rod of the limiting cylinder.

[0013] In one embodiment of the present invention, the pressing assembly includes: a pressing plate slidably mounted on the pressing base in a vertical direction, and a pressing cylinder fixed to the pressing base for driving the pressing plate to move up and down.

[0014] To achieve the above technical solution, the pressure plate is driven to descend by the pressure cylinder, and the cut pieces are pressed by the pressure plate after the pressure drive component moves into place.

[0015] In one embodiment of the present invention, a plurality of elastic pressing mechanisms are symmetrically arranged on the pressure plate. The elastic pressing mechanism includes: a pressure spring plate fixed to the pressure plate, a pressure column slidably inserted into the pressure spring plate, and an elastic member sleeved on the pressure column. One end of the elastic member abuts against the pressure spring plate, and the other end abuts against the bottom of the pressure column.

[0016] To achieve the above technical solution, when the pressure plate presses the cut piece, the bottom of the pressure column simultaneously contacts and presses the cut piece. During the downward pressing process, the pressure column moves upward to compress the elastic element, thereby providing elastic buffering for the pressure column. The pressing force can be adaptively adjusted according to the fabric thickness and elasticity, which avoids damage to thin fabrics and ensures that thick fabrics are pressed firmly, making it more adaptable.

[0017] In one embodiment of the present invention, the bottom of the pressure column is provided with a pressure step.

[0018] The above technical solution facilitates the pressing action by contacting the cut piece.

[0019] In one embodiment of this utility model, an adjusting nut is threaded to one end of the pressure column that passes through the pressure spring plate, and the adjusting nut abuts against the upper surface of the pressure spring plate.

[0020] To achieve the above technical solution, the position of the pressure column can be further adjusted and different elastic clamping forces can be adjusted by turning the adjusting nut to different depths.

[0021] In one embodiment of the present invention, the elastic pressing mechanism is provided in four sets, wherein two sets of the elastic pressing mechanism are symmetrically arranged on both sides of the pressure plate, and the other two sets of the elastic pressing mechanism are symmetrically arranged on the front side of the pressure plate.

[0022] The above technical solution achieves synchronous pressing at four points, making the pressing of the cut pieces more stable.

[0023] A second aspect of the present invention discloses a garment bag opening machine, comprising: The secondary buffer elastic pressing mechanism as described in the first aspect; and... Material support mechanism, used to support cut pieces that are about to be opened from bags.

[0024] As described above, the complete utility model name of this utility model has the following beneficial effects: This utility model provides a two-stage cushioning elastic pressing mechanism and a garment bag opening machine. The two-stage cushioning elastic pressing mechanism includes: a fixed base; a pressing platform slidably mounted on the fixed base in a vertical direction, a pressing assembly for pressing the cut pieces is installed on the pressing platform, a pressing drive for driving the pressing platform to move up and down is provided on the fixed base; a limiting buffer fixed to the pressing platform; and a buffer cylinder supported on the fixed base for supporting the limiting buffer. The piston rod of the buffer cylinder extends when the pressing drive drives the pressing platform to descend to support the limiting buffer and counteract the motion inertia of the pressing assembly, and retracts after buffering to make the pressing assembly press the cut pieces. Initially, the pressing base is in a high position, and the piston rod of the buffer cylinder is in a retracted state. During the bag opening process, the piston rod of the buffer cylinder extends, and the pressing drive drives the pressing base to descend until the piston rod of the buffer cylinder contacts the limiting buffer, thus cushioning the pressing process and offsetting the motion inertia of the pressing assembly. At this time, there is a slight gap between the pressing assembly and the cut piece. Then, the piston rod of the buffer cylinder retracts, and the pressing drive continues to drive the pressing base to descend until the piston rod of the buffer cylinder is fully retracted. At this time, the pressing assembly presses down on the surface of the cut piece, completing the pressing process. Because the buffer cylinder and the limiting buffer work together to cushion the motion inertia of the pressing assembly during the pressing process, the pressing assembly is prevented from directly impacting the cut piece, effectively preventing the fabric from shifting, wrinkling, or deforming, ensuring positioning accuracy, and the pressing stability is higher because the inertia is controlled.

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figures 1 to 3 The first aspect of this utility model provides a two-stage buffer elastic pressing mechanism, comprising: a fixed base 10; a pressing platform 20 slidably mounted on the fixed base 10 in a vertical direction, a pressing assembly 30 for pressing a cut piece 90 mounted on the pressing platform 20, a pressing drive member 40 for driving the pressing platform 20 to move up and down on the fixed base 10; a limiting buffer member 50 fixed to the pressing platform 20; and a buffer cylinder 60 supported on the fixed base 10 for supporting the limiting buffer member 50, wherein the piston rod of the buffer cylinder 60 extends when the pressing drive member 40 drives the pressing platform 20 to descend to support the limiting buffer member 50 to counteract the motion inertia of the pressing assembly 30, and retracts after buffering to press the cut piece 90 with the pressing assembly 30.

[0031] Specifically, a slide rail slider assembly is provided between the fixed base 10 and the pressing base 20 to achieve stable sliding of the pressing base 20. The pressing drive component 40 adopts a cylinder, and the base of the pressing drive component 40 is locked to the fixed base 10 by bolts. The piston rod of the pressing drive component 40 is fixed to the pressing base 20. In this way, when the pressing drive component 40 extends and retracts, it can drive the pressing base 20 to rise, fall and slide.

[0032] A positioning piece 11 is provided on the fixed base 10 between the limiting buffer 50 and the buffer cylinder 60. When the limiting buffer 50 is fully abutting against the positioning piece 11, the pressing assembly 30 presses the cut piece 90. It can be understood that the positioning piece 11 is used to limit the extreme position of the descent of the limiting buffer 50. By the positioning piece 11 abutting against the limiting buffer 50, the extreme position of the descent of the pressing assembly 30 is precisely limited, effectively improving the pressing accuracy. Furthermore, the positioning piece 11 has a through-hole 12 for the piston rod of the buffer cylinder 60 to extend out, so that the installation position of the buffer cylinder 60 can be set more compactly. Obviously, the diameter of the through-hole 12 is larger than the diameter of the piston rod of the buffer cylinder 60.

[0033] Preferably, the limiting buffer 50 is a limiting cylinder arranged opposite to the buffer cylinder 60. The diameter of the piston rod of the buffer cylinder 60 is smaller than the diameter of the through-hole 12. The piston rod of the buffer cylinder 60 extends out of the through-hole 12, and the piston rod of the limiting cylinder is also in the extended state. When the pressing base 20 descends for the first time, the piston rod of the limiting cylinder abuts against the upper surface of the positioning piece 11, and the piston rod of the buffer cylinder 60 is held against the lower bottom surface of the limiting cylinder to prevent the inertial impact force from acting directly on the cut piece 90. Moreover, the piston rod of the limiting cylinder is always in the extended state. By using a buffer cylinder as a buffer component, the air pressure inside the cylinder can be used for further buffering, effectively improving the buffering effect. Furthermore, the buffering distance can be adaptively adjusted by controlling the extension distance of the piston rod of the limiting cylinder.

[0034] It is understandable that the positioning plate 11 can be set on the piston rod of the buffer cylinder 60, rising and falling with the piston rod to determine the limiting position, with the piston rod of the limiting cylinder in an extended state to abut against the positioning plate. Alternatively, the positioning plate 11 can be omitted, and the piston rod of the limiting cylinder can be set opposite to the piston rod of the buffer cylinder 60. When the pressing base 20 descends for the first time, the piston rod of the limiting cylinder is in an extended state to directly abut against the piston rod of the buffer cylinder 60. Alternatively, the piston rod of the limiting cylinder can be set to abut against the upper surface of the buffer cylinder 60, with the piston rod of the buffer cylinder 60 abutting against the lower surface of the limiting cylinder, which can also achieve a similar buffering effect.

[0035] The pressing assembly 30 includes: a pressing plate 31 that is slidably mounted on the pressing base 20 in the vertical direction, and a pressing cylinder 32 fixed to the pressing base for driving the pressing plate 31 to move up and down. The pressing plate 31 and the pressing base 20 can also be connected by a sliding rail slider group. The pressing plate 31 is driven to descend by the pressing cylinder 32. After the pressing drive 40 moves into place, the pressing plate 31 presses the cut piece 90.

[0036] Furthermore, several elastic pressing mechanisms 70 are symmetrically arranged on the pressure plate 31. Each elastic pressing mechanism 70 includes: a pressure spring plate 71 fixed to the pressure plate 31, a pressure column 72 slidably inserted into the pressure spring plate 71, and an elastic element 73 sleeved on the pressure column 72. One end of the elastic element 73 abuts against the pressure spring plate 71, and the other end abuts against the bottom of the pressure column 72. The pressure spring plate 71 is locked to the pressure plate 31 by screws, and the pressure spring plate 71 is provided with a through hole for the pressure column 72 to slide into. The bottom of the pressure column 72 is provided with a pressure step 74. The pressure step 74 is a pressure block with a larger cross-sectional size than the pressure column 72, so as to facilitate contact with the cut piece 90 for pressing action, and can serve as a platform for abutting the elastic element 73. The elastic element 73 is a spring.

[0037] When the pressure plate 31 presses the cut piece 90, the bottom of the pressure column 72 simultaneously contacts and presses the cut piece 90. During the downward pressing process, the pressure column 72 moves upward to compress the elastic element 73, thereby providing elastic buffering for the pressure column 72. The pressing force can be adaptively adjusted according to the fabric thickness and elasticity, which avoids damage to thin fabrics and ensures that thick fabrics are pressed firmly, making it more adaptable.

[0038] In some embodiments, an adjusting nut 74 can be threaded onto one end of the pressure column 72 that passes through the pressure spring plate 71. The adjusting nut 74 abuts against the upper surface of the pressure spring plate 71. By turning the adjusting nut 74 to different depths, the position of the pressure column 72 can be further adjusted, thereby adjusting different elastic clamping forces.

[0039] In this embodiment, four sets of elastic pressing mechanisms 70 are provided, two sets of elastic pressing mechanisms 70 are symmetrically arranged on both sides of the pressure plate 31, and the other two sets of elastic pressing mechanisms 70 are symmetrically arranged on the front side of the pressure plate 31, so as to realize synchronous pressing at four points and make the cutting piece 90 pressed more stably.

[0040] Initially, the pressing base 20 is in a high position, and the piston rod of the buffer cylinder 60 is in a retracted state. During the bag opening process, the piston rod of the buffer cylinder 60 extends, and the pressing drive component 40 drives the pressing base 20 to descend until the piston rod of the buffer cylinder 60 contacts the bottom surface of the limiting buffer component 50. The buffer rod of the limiting buffer component 50 presses against the upper surface of the positioning piece 11, providing downward pressure and buffering to counteract the motion inertia of the pressing assembly 30 during the pressing process. At this time, there is a slight gap between the pressing assembly 30 and the cut piece 90, preferably 5-8mm; then the buffer cylinder... When the piston rod of cylinder 60 resets, the buffer rod of the limiting buffer component 50 retracts, and the pressing drive component 40 continues to drive the pressing base 20 to descend. At this time, the pressing assembly 30 presses down on the surface of the cut piece 90 and completes the pressing process by utilizing elastic deformation. During the pressing process, the buffer cylinder 60 and the limiting buffer component 50 cooperate to buffer the motion inertia of the pressing assembly 30, thereby avoiding the pressing assembly 30 from directly impacting the cut piece 90, effectively preventing the fabric from shifting, wrinkling, or deforming, ensuring positioning accuracy, and because the inertia is controlled, the pressing stability is higher.

[0041] A second aspect of this utility model provides a garment bag opening machine, comprising: a secondary buffer elastic pressing mechanism as described in the first aspect; and a material supporting mechanism 80 for supporting the cut piece 90 to be opened. The material supporting mechanism 80 is located directly below the secondary buffer elastic pressing mechanism. After the cut piece 90 to be opened is placed on the material supporting mechanism 80 and adjusted to a suitable position, the secondary buffer elastic pressing mechanism presses and fixes the cut piece 90 to facilitate subsequent laser bag opening operations.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
