Description

Technical Field

[0001] The present invention relates to the technical field of chopstick processing equipment, in particular to a chopstick inserting machine. Background Art

[0002] Chopsticks are long, thin sticks used to hold food or other objects between the fingers. They can be made of materials such as bamboo, wood, bone, porcelain, metal, and plastic, and come in various shapes, ranging from square to round. Most chopsticks on the market are long rods. To enhance their aesthetics, some manufacturers add decorative elements to the chopstick tips, such as electroplating or inserting decorative pieces. Chopsticks with decorative pieces typically have an inclined surface machined into the tip, which is then provided with a chopstick groove. The decorative piece is then pressed into the groove, creating a chopstick with a decorative piece. The color and pattern of the decorative piece can be freely selected, achieving a personalized and aesthetically pleasing effect. However, the current method for processing such chopsticks on the market typically involves first machining the chopsticks with chopstick grooves using a machine, and then manually pressing the decorative pieces into the corresponding chopstick grooves one by one. This results in low production efficiency and high labor costs, making it difficult for manufacturers to achieve good economic benefits. Summary of the Invention

[0003] The purpose of the present invention is to provide a chopstick inserting machine, which can realize the automatic assembly of chopsticks and decorative sheets, has the advantage of high production efficiency, and also saves a lot of labor costs, which can bring good economic benefits to the enterprise.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a chopstick inserting machine for pressing a decorative sheet into the chopstick groove of chopsticks, wherein the chopstick heads are provided with an inclined surface, and the chopstick groove is arranged on the inclined surface; it comprises a frame, wherein a feeding mechanism for transmitting chopsticks is provided on the frame, and a feeding mechanism for placing the chopsticks one by one on the feeding mechanism is provided in the feeding direction of the feeding mechanism, a chopstick rotating mechanism for rotating the chopsticks uniformly to a position where the chopstick groove is facing upward, a loading device for pre-loading the decorative sheet into the chopstick groove of the chopsticks, a sheet pressing mechanism for pressing the decorative sheet tightly against the chopstick groove of the chopsticks, and a discharging hopper for discharging the chopsticks.

[0005] By adopting the above technical solution, during production, the chopsticks with grooves are placed on the feeding mechanism, which places the chopsticks one by one on the feeding mechanism. The feeding mechanism drives the chopsticks to move horizontally. During the translation process, the chopsticks are uniformly rotated to a state with the chopstick grooves facing upwards by the chopstick rotating mechanism. After the chopsticks are rotated to the correct direction, the feeding mechanism moves the chopsticks horizontally to the processing station of the loading device. The loading device pre-installs the decorative sheets on the chopstick grooves one by one. When the chopsticks pre-installed with the decorative sheets are moved to the processing station of the pressing mechanism, the pressing mechanism presses the decorative sheets into the chopstick grooves, completing the assembly process of the decorative sheets and chopsticks. Therefore, the chopstick inserting machine can realize the automatic assembly of chopsticks and decorative sheets, has the advantages of high production efficiency, and also saves a lot of labor costs, which can bring good economic benefits to the enterprise.

[0007] By adopting the above technical solution, by arranging positioning plates on the chain links and positioning recesses on the positioning plates, the two ends of the chopsticks are respectively embedded in the positioning recesses of the two positioning plates, and then the feeding motor is used as the power source to prompt the sprocket chain transmission structure to drive the chopsticks for transmission. The transmission is smooth and reliable, which is conducive to the precise insertion of the chopsticks.

[0008] The present invention is further configured as follows: the unloading mechanism includes a unloading seat, a unloading hopper, a first cylinder, a second cylinder and a feeding plate; the unloading seat is arranged on the mounting seat of the feeding mechanism; the protruding end of the first cylinder is linked to the unloading hopper for driving the unloading hopper to move back and forth; the protruding end of the second cylinder is linked to the feeding plate; the feeding plate is arranged between the unloading hopper and the unloading seat; the unloading hopper, the feeding plate and the mounting seat are respectively provided with a first passing opening, a second passing opening and a third passing opening for chopsticks to pass through; the first passing opening and the third passing opening are staggered; and two retaining edges are provided at the position corresponding to the third passing opening at the bottom of the unloading seat for guiding the chopsticks into the positioning recess.

[0009] By adopting the above technical solution, after the chopsticks are placed in the discharge hopper, the working frequency of the second cylinder can be set according to the movement frequency of the chain, that is, when the positioning recess on the chain positioning plate moves to the bottom of the discharge mechanism, a chopstick at the bottom of the discharge hopper passes through the first opening and falls into the second opening of the feeding plate. The feeding plate is pulled by the second cylinder, prompting the chopsticks in the second opening of the feeding plate to move and pass through the third opening of the discharge seat and fall into the positioning recess of the corresponding positioning plate, thereby realizing stable discharge of the chopsticks.

[0038] The present invention is further configured such that a limit block is provided on the side of the pressure seat for limiting the lower stroke of the pressure seat.

[0039] By adopting the above technical solution, the pressure seat can be limited, thereby preventing the rotating shaft on the pressure plate from crushing the chopsticks when the pressure seat moves downward.

[0040] The present invention is further configured such that a first photoelectric sensor for detecting the positioning piece is also installed on the chopstick pressing rack.

[0041] By adopting the above technical solution, when the first photoelectric sensor detects the positioning piece, the feeding mechanism stops moving, and the feeding assembly feeds out a decorative piece on the turntable assembly and inserts it into the chopstick slot of the chopsticks.

[0043] By adopting the above technical solution, when the driving part is working, the slider is driven forward by the connecting rod structure, and the pressure rod swings downward, causing the clamping protrusion on the pressure rod to press just on the chopstick head, thereby pressing the decorative piece into the chopstick groove of the chopsticks. This structure is suitable for inclined surface clamping and has the advantages of good clamping effect and high pass rate.

[0044] The present invention is further configured as follows: the connecting rod structure includes a rocker rod, a first connecting rod and a second connecting rod, the lower end of the rocker rod is hinged to the sheet pressing seat, the upper end of the rocker rod is connected to the driving member, one end of the first connecting rod is hinged to the middle of the rocker rod, the other end of the first connecting rod is hinged to the upper end of the pressure rod, the second connecting rod is arranged below the first connecting rod, and one end of the second connecting rod is hinged to the rocker rod, and the other end of the second connecting rod is hinged to the slider.

[0045] By adopting the above technical solution, when the rocker arm swings forward, it pushes the first connecting rod and the second connecting rod to move. The first connecting rod causes the pressure rod to swing downward, and at the same time, the second connecting rod drives the pressure rod forward by pushing the slider forward, thereby achieving the effect of the pressure rod pressing down during the forward movement. There is no need for multiple action combinations, and only one driving component is required for the entire process. This not only reduces equipment costs, but also significantly improves production efficiency.

[0046] The present invention is further configured such that the driving member is a cylinder, the fixed end of the driving member is hinged to the tablet pressing seat, and the protruding end of the driving member is hinged to the upper end of the rocker arm.

[0047] By adopting the above technical solution, the cylinder has a simple structure and quick action, which is not only convenient for assembly but also has high working efficiency.

[0048] The present invention is further configured such that a slide rail is provided on the tablet pressing seat, a slideway with an inverted T-shaped cross section is provided on the slide rail, the shape of the slider is adapted to the slideway, and the slider is slidably arranged on the slideway.

[0049] By adopting the above technical solution, the slide rail plays a role of limiting and guiding the slider, ensuring that the slider can move forward or backward stably under the action of external force.

[0050] The present invention is further configured such that the cross section of the pressing protrusion is trapezoidal in shape.

[0051] By adopting the above technical solution, the trapezoidal pressing protrusion is not only less likely to interfere with other components during the pressing operation, but also the trapezoidal inclined surface can be adapted to the inclined surface of the chopstick head, which can better press the decorative sheet into the chopstick groove of the chopsticks.

[0052] The present invention is further configured such that a detection mechanism is further provided on the side of the feeding mechanism, the detection mechanism includes a measuring piece assembly and a waste rejection assembly; the measuring piece assembly includes a measuring piece frame, a measuring piece cylinder, a connecting plate and a push rod, the measuring piece cylinder is installed on the measuring piece frame, the connecting plate is arranged on the protruding end of the measuring piece cylinder, a circular hole is opened on the connecting plate, the push rod passes through the circular hole, and a reset spring is provided between the lower end of the connecting plate and the push rod, the reset spring applies a downward force to the push rod, and a second photoelectric sensor for detecting the push rod is also installed on the connecting plate; the waste rejection assembly includes a waste rejection cylinder, a push head and a waste box, the waste rejection cylinder and the waste box are respectively arranged on both sides of the feeding mechanism, and the protruding end of the waste rejection cylinder is linked to the push head to drive the push head to push out the waste into the waste box.

[0053] By adopting the above technical solution, the chopsticks are quality inspected by the detection mechanism. If the decorative piece is inserted into the chopstick groove, when the connecting plate drives the push rod downward, the push rod is restricted by the decorative piece and moves upward relative to the connecting plate, so that the second photoelectric sensor detects the push rod, thereby judging that the chopsticks are qualified; if the decorative piece is not installed in the chopstick groove of the chopsticks, the push rod will be inserted into the chopstick groove, and the push rod will not be affected by the reaction force and retreat, and the second photoelectric sensor cannot detect the push rod, thereby judging that the chopsticks are unqualified. The unqualified chopsticks are pushed into the waste box through the waste rejection component, thereby ensuring the qualified rate of chopstick processing.

[0054] The present invention is further configured such that a plurality of feed openings for the decorative sheets to pass through are provided on the mounting seat along the feeding direction of the feeding mechanism, and bucket pieces are provided at positions below the mounting seat corresponding to the feed openings.

[0055] By adopting the above technical solution, in the case where there are no chopsticks on the positioning piece, after the delivery component delivers the decorative piece, the decorative piece will fall on the table top of the mounting seat. When the chopsticks move with the feeding mechanism, the scattered decorative pieces can be swept to the discharge port, and the decorative pieces fall into the bucket piece below through the discharge port, effectively collecting the scattered decorative pieces, thereby ensuring the cleanliness of the mounting seat table.

The unloading hopper 21, the feeding plate 24 and the mounting seat 11 are respectively provided with a first opening 25, a second opening 26 and a third opening 27 for the chopsticks 1 to pass through. The first opening 25 and the third opening 27 are staggered. The bottom of the unloading seat 20 corresponding to the third opening 27 is provided with two retaining edges 28 for guiding the chopsticks 1 into the positioning recess 19. After the chopsticks 1 are placed in the discharge hopper 21, the working frequency of the second cylinder 23 can be set according to the moving frequency of the chain 15. That is, when the positioning recess 19 on the positioning piece 18 of the chain 15 moves to the bottom of the discharge mechanism 6, a chopstick 1 at the bottom of the discharge hopper 21 passes through the first opening 25 and falls into the second opening 26 of the feeding plate 24. The feeding plate 24 is pulled by the second cylinder 23, prompting the chopsticks 1 in the second opening 26 of the feeding plate 24 to move and pass through the third opening 27 of the discharge seat 20 and fall into the positioning recess 19 of the corresponding positioning piece 18, thereby realizing stable discharge of the chopsticks 1.

[0080] As attached Figure 2 、 6As shown in Figures 7 and 8, the chopstick turning mechanism 7 includes an alignment component 29 and a chopstick turning component 30; the alignment component 29 includes an alignment seat 31, an alignment motor 32, a first shaft 33, a second shaft 34, a driving pulley 35, a driven pulley 36 and an alignment belt 37, the first shaft 33 and the second shaft 34 are rotatably mounted on the alignment seat 31, the alignment motor 32 is mounted on the alignment seat 31, and the motor shaft of the alignment motor 32 is linked to the first shaft 33, the driving pulley 35 and the driven pulley 36 are linked to the first shaft 33, and the driving pulley 35 and the driven pulley 36 are linked to the first shaft 33. On the first shaft 33 and the second shaft 34, the alignment belt 37 is covered on the driving pulley 35 and the driven pulley 36, and a plurality of material-prying protrusions 38 are evenly arranged on the surface of the alignment belt 37 along the length direction, and the material-prying protrusions 38 and the alignment belt 37 are an integrated structure; the chopstick turning assembly 30 includes a chopstick turning seat 39, a rotating cylinder 40 and two cylinder clamps 41, and the rotating cylinder 40 is a finger cylinder, and the rotating cylinder 40 is installed on the chopstick turning seat 39, and the two cylinder clamps 41 are respectively installed on the two movable ends of the rotating cylinder 40. First, the chopsticks 1 are adjusted to a uniform orientation through the alignment component 29, and the alignment motor 32 drives the alignment belt 37 to move through the pulley transmission. The material-prying protrusion 38 on the alignment belt 37 will move the chopsticks 1 to rotate. When the inclined surface 3 at the tip of the chopsticks 1 is facing downward, since the material-prying protrusion 38 is no longer in direct contact with the inclined surface 3, the chopsticks 1 can keep the chopstick groove 2 facing downward; then the chopsticks 1 are flipped 180° by the turning block component, that is, the rotating cylinder 40 drives the cylinder clamp 41 to clamp the chopsticks 1 and flip it 180°, so that the chopstick groove 2 on the chopsticks 1 is set upward, so as to facilitate the subsequent insertion of the decorative piece into the chopstick groove 2 of the chopsticks 1.

[0081] As attached Figure 6 and attached Figure 7 As shown, the alignment assembly 29 further includes a tensioning wheel 42 and a third rod 43. The third rod 43 is disposed on the alignment seat 31. The tensioning wheel 42 is rotatably mounted on the third rod 43 and is disposed above or below the driving pulley 35 and the driven pulley 36. The tensioning wheel 42 abuts against the inner side of the alignment belt 37. The tensioning wheel 42 keeps the alignment belt 37 taut, making the transmission more stable and ensuring that the material-moving protrusion 38 on the alignment belt 37 can smoothly move the chopsticks 1.

[0082] As attached Figure 7 As shown, the alignment seat 31 is provided with a vertical sliding hole 44, and the third rod 43 is vertically slidably mounted on the sliding hole 44. A locking screw 45 is provided at the bottom of the alignment seat 31 and extends into the sliding hole 44. The third rod 43 is provided with a screw hole 46 that cooperates with the locking screw 45. Rotating the locking screw 45 allows the position of the tensioning wheel 42 to be adjusted in real time as needed, thereby facilitating adjustment of the tension of the alignment belt 37.

[0083] As attached Figure 7As shown, the alignment seat 31 includes a flip plate 47 and a bracket 48. The flip plate 47 is provided with an inclined block 49, which is rotatably connected to the bracket 48 via a pin 50. The bracket 48 is also provided with a locking member 51 for locking the inclined block 49. This design allows the movement angle of the alignment belt 37 to be adjusted, so that the alignment belt 37 is arranged obliquely, that is, it is adapted to the inclined surface 3 at the chopstick head 1, thereby preventing the chopsticks 1 from still contacting the alignment belt 37 when the inclined surface 3 is facing downward.

[0084] As attached Figure 7 As shown, the locking member 51 includes an adjustment screw 52 and a locking nut 53. The bracket 48 is provided with a through hole 54, and the inclined block 49 is provided with an arc-shaped adjustment hole 55 corresponding to the through hole 54. The adjustment hole 55 is used to allow the adjustment screw 52 to move. The adjustment screw 52 passes through the through hole 54 and the adjustment hole 55 in sequence. The locking nut 53 is threadedly connected to the adjustment screw 52 and abuts against the side of the inclined block 49. After loosening the locking nut 53, the angle of the inclined block 49 can be adjusted. After the angle adjustment is completed, the locking nut 53 is tightened. The adjustment structure is simple and reliable, and the operation is very convenient.

[0085] As attached Figure 6 As shown, the alignment seat 31 is provided with an upper baffle 56 at a position above the alignment belt 37. The upper baffle 56 not only limits the chopsticks 1, but also prevents foreign matter from falling onto the alignment belt 37 and affecting the normal turning of the chopsticks 1.

[0086] As attached Figures 9-13 As shown, the film loading device 8 includes a vibration plate 57, a film feeding mechanism 58, and a chopstick pressing mechanism 59. The film feeding mechanism 58 includes a turntable assembly 60 and a delivery assembly 61. The vibration plate 57 sequentially delivers the decorative film to the turntable assembly 60 of the film feeding mechanism 58. The vibration plate 57 is a mature product on the market, so its specific structure is not described in detail here. While the chopstick pressing mechanism 59 presses the chopsticks 1, the delivery assembly 61 on the film feeding mechanism 58 pushes the corresponding decorative film on the turntable assembly 60 into the chopstick groove 2 of the chopsticks 1. This design can sequentially push the decorative film into the chopstick groove 2 of the corresponding chopsticks 1. Subsequently, it is only necessary to press the decorative film into the chopstick groove 2. Its film loading action is fast and reliable, and the production efficiency is high.

[0087] As attached Figure 10 and attached Figure 11As shown, the turntable assembly 60 includes a turntable frame 62, a turntable body 63, and a turntable motor 64. The turntable body 63 is annular and rotatably mounted on the turntable frame 62. The turntable motor 64 is linked to the turntable body 63 via a transmission member 65 to drive the turntable body 63 to rotate. The turntable body 63 has a plurality of transport slots 66 evenly distributed along the circumference for placing decorative sheets. The transport slots 66 on the turntable body 63 are used to place decorative sheets. When the turntable motor 64 drives the turntable body 63 to rotate via the transmission member 65, the vibrating disc 57 transports the decorative sheets to the corresponding transport slots 66 on the turntable body 63. The ejection assembly 61 ejects the decorative sheets from the corresponding transport slots 66 on the turntable body 63. The feeding and discharging of decorative sheets are carried out simultaneously, greatly improving production efficiency.

[0088] As attached Figure 11 As shown, the transmission member 65 includes a first gear 67 and a second gear 68. The first gear 67 is a small gear, and the second gear 68 is a large ring gear. The first gear 67 is mounted on the motor shaft of the turntable motor 64 in a linkage manner, and the second gear 68 is mounted on the turntable body 63 in a linkage manner. The first gear 67 and the second gear 68 are meshed with each other, and both the first gear 67 and the second gear 68 have helical teeth. The transmission member 65 is a gear transmission structure, that is, the turntable motor 64 drives the turntable body 63 to rotate through the gear transmission. The transmission structure is simple and reliable, the operation is stable, and the assembly and production are very convenient.

[0089] As attached Figure 11 As shown, the turntable frame 62 is provided with multiple sets of support members 69 arranged in a circular array. The support members 69 include a bearing shaft 70 and two limit bearings 71 rotatably mounted on the bearing shaft 70. A spacer is provided between the two limit bearings 71. The outer peripheries of the two limit bearings 71 are in contact with the inner periphery of the second gear 68. The outer peripheries of the limit bearings 71 are provided with limit flanges 72, which respectively abut the upper and lower ends of the second gear 68. The support members 69 can support and limit the second gear 68 and the turntable body 63, thereby improving the rotational stability of the second gear 68 and the turntable body 63.

[0090] As attached Figure 10As shown, the turntable frame 62 is mounted with an inner retaining ring 73 disposed on the inner circumference of the turntable body 63 and an outer retaining ring 74 disposed on the outer circumference of the turntable body 63. The outer retaining ring 74 is provided with an inlet 75 for the decorative sheet to enter and an outlet 76 for the decorative block to exit. The inner retaining ring 73 is provided with a through hole 77 for the operating end of the delivery assembly 61 to pass through. A cover plate 78 is also mounted on the upper portion of the turntable body 63 to confine the decorative sheet within the transport trough 66. The cover plate 78, the turntable body 63, and the second gear 68 are connected together by multiple latches. The inner retaining ring 73, the outer retaining ring 74, and the cover plate 78 can confine and protect the decorative sheet disposed in the transport trough 66, ensuring that the decorative sheet is not thrown out of the transport trough 66 when the turntable body 63 rotates.

[0091] As attached Figure 10 As shown, the delivery assembly 61 includes a delivery cylinder 79 and a ejector pin 80. The delivery cylinder 79 is mounted on the turntable frame 62. The extended end of the delivery cylinder 79 is linked to the ejector pin 80 to drive the ejector pin 80 back and forth. The turntable frame 62 is also provided with a guide seat 81, which is provided with a guide hole 82 that cooperates with the ejector pin 80. When the extended end of the delivery cylinder 79 drives the ejector pin 80 to be pushed out, the ejector pin 80 pushes the decorative piece out of the corresponding transport slot 66 of the turntable body 63 and inserts it into the chopstick slot 2 of the corresponding chopstick 1. The structure is simple and the operation is fast.

[0092] As attached Figure 12 As shown, the chopstick pressing mechanism 59 includes a chopstick pressing frame 83, a slide cylinder 84 arranged on the chopstick pressing frame 83, and a pressing seat 85 arranged on the movable end of the slide cylinder 84. A pressing plate 86 is installed on the pressing seat 85. A pair of mounting protrusions 87 are provided at the bottom of the pressing plate 86. A rotating shaft 88 is rotatably connected between the two mounting protrusions 87 for pressing on the upper end position of the chopstick groove 2 corresponding to the chopsticks 1. The structure of the pressing plate 86 and the rotating shaft 88 can be arranged in multiple groups side by side. When the slide cylinder 84 drives the pressing seat 85 downward, the rotating shaft 88 on the pressing seat 85 can not only press on the upper end position of the chopstick groove 2 of the chopsticks 1 to ensure the stability of the inserting operation, but also when inserting the decorative piece, the rotating shaft 88 can limit the upper stroke of the decorative piece to ensure that it is accurately inserted into the chopstick groove 2 of the chopsticks 1.

[0093] As attached Figure 12 and attached Figure 13As shown, the pressure seat 85 is provided with a vertical sliding cavity 89, and the pressure plate 86 is vertically slidably disposed on the sliding cavity 89. A pressure spring 90 is also disposed within the sliding cavity 89 to act on the pressure plate 86. The pressure plate 86 is provided with a vertically extending limiting groove 91, and the pressure seat 85 is provided with a guide screw 92 that extends into the limiting groove 91. This design can cushion the impact of the rotating shaft 88 when it contacts the chopsticks 1. When the pressure seat 85 drives the pressure plate 86 downward, the rotating shaft 88 on the pressure plate 86 and the chopsticks 1 generate a significant impact.

[0094] As attached Figure 12 As shown, the side of the press seat 85 is provided with a limit block 93 for limiting the lower stroke of the press seat 85. The limit block 93 can limit the press seat 85, thereby preventing the rotating shaft 88 on the pressing plate 86 from crushing the chopsticks 1 when the press seat 85 moves downward.

[0095] As attached Figure 12 As shown, the chopstick pressing frame 83 is also equipped with a first photoelectric sensor 94 for detecting the positioning piece 18. When the first photoelectric sensor 94 detects the positioning piece 18, the feeding mechanism 5 stops moving, and the feeding assembly 61 feeds out a decorative piece on the turntable assembly 60 and inserts it into the chopstick slot 2 of the chopsticks 1.

[0096] As attached Figures 14-16 As shown, the pressing mechanism 9 includes a pressing seat 95, a driving member 96, a connecting rod structure 97, a slider 98, and a pressure rod 99. The driving member 96 is disposed on the pressing seat 95. The slider 98 is slidably disposed on the pressing seat 95 in a direction close to or away from the chopsticks 1. One end of the pressure rod 99 is hinged to the slider 98. The other end of the pressure rod 99 is connected to the driving member 96 via the connecting rod structure 97. The slider 98 is also connected to the driving member 96 via the connecting rod structure 97. The pressure rod 99 is provided with a pressing protrusion 100 for pressing the decorative sheet against the chopstick groove 2 of the chopsticks 1. When the driving member 96 is in operation, the slider 98 is driven forward by the connecting rod structure 97, and the pressure rod 99 swings downward, causing the pressing protrusion 100 on the pressure rod 99 to press exactly against the chopstick tip of the chopsticks 1, thereby pressing the decorative sheet against the chopstick groove 2 of the chopsticks 1. This structure is suitable for pressing the inclined surface 3 and has the advantages of good pressing effect and high qualified rate.

[0097] As attached Figure 14As shown, the connecting rod structure 97 includes a rocker rod 101, a first connecting rod 102 and a second connecting rod 103. The length of the first connecting rod 102 is greater than that of the second connecting rod 103. The lower end of the rocker rod 101 is hinged to the tablet pressing seat 95. Specifically, a groove is opened on the tablet pressing seat 95, and the lower end of the rocker rod 101 is embedded in the groove. The upper end of the rocker rod 101 is connected to the driving member 96. One end of the first connecting rod 102 is hinged to the middle of the rocker rod 101, and the other end of the first connecting rod 102 is hinged to the upper end of the pressure rod 99. The second connecting rod 103 is arranged below the first connecting rod 102, and one end of the second connecting rod 103 is hinged to the rocker rod 101, and the other end of the second connecting rod 103 is hinged to the slider 98. When the rocker arm 101 swings forward, it pushes the first connecting rod 102 and the second connecting rod 103 to move. The first connecting rod 102 causes the pressure rod 99 to swing downward. At the same time, the second connecting rod 103 drives the pressure rod 99 forward by pushing the slider 98 forward, thereby achieving the effect of the pressure rod 99 pressing down during the forward movement. There is no need for multiple action combinations. Only one driving part 96 is required for the entire process, which not only reduces equipment costs but also significantly improves production efficiency.

[0098] The driving member 96 is a cylinder, the fixed end of which is hinged to the tablet pressing seat 95, and the extended end of which is hinged to the upper end of the rocker 101. The cylinder has a simple structure and moves quickly, which is not only convenient for assembly but also highly efficient.

[0099] As attached Figure 14 As shown, the tablet pressing seat 95 is provided with a slide rail 104, and the slide rail 104 is provided with a slideway 105 with an inverted T-shaped cross section. The shape of the slider 98 is adapted to the slideway 105, and the slider 98 is slidably arranged on the slideway 105. The slide rail 104 serves to limit and guide the slider 98, ensuring that the slider 98 can stably move forward or backward under the action of external force.

[0100] As attached Figure 16 As shown, the cross-section of the pressing protrusion 100 is trapezoidal in shape. The trapezoidal pressing protrusion 100 is not only less likely to interfere with other components during the tablet pressing operation, but also the trapezoidal inclined surface 3 can be adapted to the inclined surface 3 of the chopstick head 1, thereby better pressing the decorative sheet into the chopstick groove 2 of the chopstick 1.

[0101] As attached Figure 17 and attached Figure 18As shown, the side of the feeding mechanism 5 is further provided with a detection mechanism 106, and the detection mechanism 106 includes a measuring piece assembly 107 and a waste rejection assembly 108; the measuring piece assembly 107 includes a measuring piece frame 109, a measuring piece cylinder 110, a connecting plate 111 and a push rod 112, the measuring piece cylinder 110 is installed on the measuring piece frame 109, the connecting plate 111 is provided on the protruding end of the measuring piece cylinder 110, a circular hole 113 is opened on the connecting plate 111, the push rod 112 passes through the circular hole 113, and a reset spring 114 is provided between the lower end of the connecting plate 111 and the push rod 112, wherein the push rod 112 is provided with an upper retaining spring at a position above the connecting plate 111 for limiting the push rod 112. A lower retaining spring 114 is provided at the position of the ejector rod 112 below the connecting plate 111 to support a return spring 114. The two ends of the return spring 114 respectively rest on the lower retaining spring and the connecting plate 111. The return spring 114 applies a downward force to the ejector rod 112. A second photoelectric sensor 115 for detecting the ejector rod 112 is also installed on the connecting plate 111. The waste rejection assembly 108 includes a waste rejection cylinder 116, a ejector head 117 and a waste box 118. The waste rejection cylinder 116 and the waste box 118 are respectively arranged on both sides of the feeding mechanism 5. The protruding end of the waste rejection cylinder 116 is linked to the ejector head 117 to drive the ejector head 117 to push the waste into the waste box 118. The chopsticks 1 are quality-inspected by the detection mechanism 106. If the decorative sheet is inserted into the chopstick groove 2, the connecting plate 111 drives the push rod 112 downward, and the push rod 112 is restricted by the decorative sheet and moves upward relative to the connecting plate 111, so that the second photoelectric sensor 115 detects the push rod 112, thereby judging that the chopsticks 1 are qualified; if the decorative sheet is not installed in the chopstick groove 2 of the chopsticks 1, the push rod 112 will be inserted into the chopstick groove 2, and the push rod 112 will not be affected by the reaction force and retreat, and the second photoelectric sensor 115 cannot detect the push rod 112, thereby judging that the chopsticks 1 are unqualified. The unqualified chopsticks 1 are pushed into the waste box 118 by the waste rejection component 108, thereby ensuring the qualified rate of the chopstick 1 processing.

[0102] As attached Figure 19 As shown, the mounting base 11 is provided with a plurality of discharge openings 119 for passing decorative sheets along the feeding direction of the feeding mechanism 5, and a bucket piece 120 is provided at a position below the discharge openings 119 corresponding to the mounting base 11. In the case where there are no chopsticks 1 on the positioning piece 18, after the delivery assembly 61 delivers the decorative sheet, the decorative sheet will fall on the table surface of the mounting base 11. When the chopsticks 1 move with the feeding mechanism 5, the scattered decorative sheets can be swept to the discharge openings 119. The decorative sheets will then fall into the bucket piece 120 below through the discharge openings 119, effectively collecting the scattered decorative sheets and ensuring the cleanliness of the table surface of the mounting base 11.
