Description

Technical Field

[0001] This invention belongs to the field of food packaging machinery technology, specifically relating to a high-speed fully automatic buckle fastening machine. Background Technology

[0002] In the packaging process of baked goods (such as bread and toast) and some snack foods, plastic straps are commonly used to seal the bag openings to ensure product freshness, moisture protection, and improve appearance. However, currently, the vast majority of strapping processes used in the packaging of such foods still rely on manual operation or semi-automatic equipment. Operators need to manually adjust the bag opening, feed it into the equipment, or have the equipment perform initial tightening before manually assisting in feeding, breaking, and finally locking the strap. This model has significant drawbacks: First, it has low production efficiency, making it difficult to match the pace of modern high-speed food production lines, thus becoming a bottleneck in production capacity; second, although the operation is carried out under clean operating procedures, direct manual contact with the bag opening still poses potential food safety and hygiene risks.

[0003] Therefore, there is an urgent need for a fully automated equipment that can automatically, accurately, and efficiently complete the entire process of sealing food packaging bags, and ensure food hygiene, safety, and packaging stability, in order to adapt to the high-speed and high-standard development trend of the food industry. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic buckle machine that achieves high speed, stability, flexibility and compatibility.

[0005] To address the aforementioned problems, this invention provides a high-speed fully automatic button-fastening machine, comprising: a frame; a conveying assembly for conveying bagged products; a button-feeding assembly for sequentially feeding a row of buttons towards the conveying platform of the conveying assembly; a bag drawstring assembly located on one side of the conveying assembly, which, together with the conveying assembly, feeds the bag opening of the product to be buttoned into the middle hole of the end button; a button-breaking assembly for removing a button with the bag opening in the middle hole from the main body of the row of buttons; and a controller for controlling the button-feeding assembly, the bag drawstring assembly, and the button-breaking assembly to alternately perform actions according to the timing of the bag drawstringing process; the button-feeding assembly, the bag drawstring assembly, and the button-breaking assembly are all fixed on the frame.

[0006] The fully automatic buckle-sealing machine of this invention first uses a conveying component and a packaging bag drawstring assembly to work together to feed the bag opening of the product to be sealed into the middle hole of the end buckle. Then, a buckle-breaking component removes the buckle with the bag opening sealed from the main buckle assembly. Finally, a buckle-feeding component replenishes a new buckle for the next work cycle. Therefore, this invention, through the coordinated operation of the conveying component, packaging bag drawstring assembly, buckle-breaking component, and buckle-feeding component, achieves a fully automatic cyclical operation of "bag opening fed into the buckle hole → buckle cut → conveying the sealed product → automatic replenishment of new buckles." This equipment not only significantly improves the automation level, operational accuracy, and production efficiency of the food packaging bag sealing process, but also effectively ensures food hygiene and safety and the stability of the packaging seal.

[0007] In some embodiments, a support frame is mounted on the machine frame. The bag drawstring assembly includes a vertical plate mounted on the support frame, an outer roller group and an inner roller group for clamping the bag opening, and a first power member mounted on the vertical plate for driving the outer roller group and the inner roller group to rotate. The outer roller group and the inner roller group are arranged opposite each other and form a gap in the horizontal direction that allows the tie to pass through. Thus, the first power member drives the outer roller group and the inner roller group to operate synchronously, and the two cooperate to clamp and convey the bag opening from the conveying assembly from both the inside and outside. Since the tie to be used is pre-placed in the gap between the outer roller group and the inner roller group, when the outer roller group, the inner roller group, and the conveying assembly work together to push the bag opening of the product forward as a whole, the front end of the bag opening will accurately abut into the middle hole of the tie at the end; as the pushing action continues, the bag opening is smoothly tied into the tie, completing the tying process.

[0008] In some embodiments, the outer roller assembly includes an outer active conveyor roller, a first outer driven upper pressure roller, a first synchronous belt that synchronously connects the outer active conveyor roller and the first outer driven upper pressure roller, and a first outer driven lower pressure roller that is tangentially disposed to the outer periphery of the first outer driven upper pressure roller; the inner roller assembly includes an inner active conveyor roller, a first inner driven upper pressure roller, a second synchronous belt that synchronously connects the inner active conveyor roller and the first inner driven upper pressure roller, and a first inner driven lower pressure roller that is tangentially disposed to the outer periphery of the first inner driven upper pressure roller; the first power component is a first motor, the outer active conveyor roller and the inner active conveyor roller are coaxially connected and connected to the power shaft of the first motor, the first outer driven upper pressure roller is coaxially connected to the first inner driven upper pressure roller, and the first outer driven lower pressure roller is coaxially connected to the first inner driven lower pressure roller. Thus, the outer side of the bag opening is clamped and conveyed by the cooperation of the first outer driven upper pressure roller and the first outer driven lower pressure roller, while the inner side of the bag opening is clamped and conveyed by the cooperation of the first inner driven upper pressure roller and the first inner driven lower pressure roller, thereby completing the clamping and conveying of the bag opening on both the inner and outer sides.

[0009] In some embodiments, the outer roller assembly further includes a second outer driven upper pressure roller, a second outer driven lower pressure roller tangentially arranged to its outer periphery, and a third synchronous belt synchronously connecting the first outer driven lower pressure roller and the second outer driven lower pressure roller; the inner roller assembly further includes a second inner driven upper pressure roller, a second inner driven lower pressure roller tangentially arranged to its outer periphery, and a fourth synchronous belt synchronously connecting the first inner driven lower pressure roller and the second inner driven lower pressure roller, with the first outer driven upper pressure roller and the second outer driven upper pressure roller arranged side by side in the horizontal direction. Thus, by adding a second outer driven upper pressure roller and a corresponding second outer driven lower pressure roller to the outer roller assembly and connecting them via the third synchronous belt, the outer side of the bag opening can be clamped more evenly, improving conveying stability; simultaneously, by adding a second inner driven upper pressure roller and a corresponding second inner driven lower pressure roller to the inner roller assembly and connecting them via the fourth synchronous belt, the inner side of the bag opening can be clamped more evenly, improving conveying stability.

[0010] In some embodiments, the snap-off assembly includes a fixed plate mounted on a support frame, a second power component mounted on the fixed plate, a first linear reciprocating mechanism driven by the second power component, and a pull block driven by the first linear reciprocating mechanism to move horizontally, the horizontal position of the pull block corresponding to the end snap of the row of snap fasteners. Thus, by controlling the movement of the pull block, the finished product is detached from the row of snap fasteners and then conveyed away by the conveying assembly.

[0011] In some embodiments, the second power component is a second motor, and the first linear reciprocating mechanism includes a first crank powered by the second motor, a first sliding column connected to the outer end of the first crank, and a first sliding block slidably connected to the first sliding column. A first guide rail arranged horizontally is mounted on a fixed plate, and the first sliding block is slidably connected to the first guide rail. One end of the first sliding block has a first oblong hole, through which the first sliding column passes and can slide. The other end of the first sliding block is fixedly connected to a pull block. Thus, the first crank drives the first sliding column to slide in the first oblong hole of the first sliding block, thereby driving the first sliding block to slide on the first guide rail, and further driving the pull block to achieve linear reciprocating movement.

[0012] In some embodiments, the buckle feeding assembly includes a third power member mounted on a fixed plate and a second linear reciprocating mechanism driven by the third power member for intermittently conveying a row of buckles downwards. Thus, the intermittent downward conveying of the row of buckles is achieved by the second linear reciprocating mechanism.

[0013] In some embodiments, the third power component is a third motor, and the second linear reciprocating mechanism includes a second crank powered by the third motor, a second sliding column connected to the outer end of the second crank, and a second sliding block slidably connected to the second sliding column. A second guide rail arranged vertically is mounted on the fixed plate, and the second sliding block is slidably connected to the second guide rail. One end of the second sliding block has a second oblong hole, through which the second sliding column passes and can slide. An actuating element for driving the buckle to move downward is fixedly connected to the second sliding block. The second crank drives the second sliding column to slide in the second oblong hole of the second sliding block, which in turn drives the second sliding block to slide on the second guide rail, thereby driving the actuating element to perform linear reciprocating motion, completing the buckle replenishment action.

[0014] In some embodiments, the fixing plate has a vertical slot, the actuating member is inclined and its outer end passes through the slot and abuts against the middle hole of the buckle.

[0015] In some embodiments, the high-speed fully automatic buckle-pressing machine further includes a buckle roll placement mechanism located above the buckle-feeding assembly. The buckle roll placement mechanism includes a bracket and a rotatable turntable mounted on the bracket. Winding a row of buckles onto the rotatable turntable facilitates buckle feeding, thereby improving the conveying stability of the row of buckles. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. The terms "comprising," "including," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.

[0020] Figure 1 The diagram schematically illustrates a high-speed fully automatic buckle machine according to one embodiment of the present invention, combined with... Figure 2As shown, the high-speed fully automatic buckle-fastening machine includes a frame 1; a conveying assembly 2, a buckle-feeding assembly 3, a bag drawstring assembly 4, a buckle-breaking assembly 5, and a controller 6. The buckle-feeding assembly 3, the bag drawstring assembly 4, and the buckle-breaking assembly 5 are all fixed on the frame 1. The conveying assembly 2 is used to convey bagged products and can be a belt conveyor. The buckle-feeding assembly 3 is used to sequentially feed the row of buckles 100 towards the conveying platform of the conveying assembly 2. The bag drawstring assembly 4 is located on one side of the conveying assembly 2 and works with the conveying assembly 2 to feed the bag opening of the product to be buckled into the middle hole of the end buckle. The buckle-breaking assembly 5 is used to remove a buckle with the bag opening in the middle hole from the main body of the row of buckles 100. The controller 6 is used to control the buckle-feeding assembly 3, the bag drawstring assembly 4, and the buckle-breaking assembly 5 to perform their actions alternately according to the timing of the bag drawstring process.

[0021] The fully automatic buckle-sealing machine based on the above structure first coordinates the actions of the conveying component 2 and the packaging bag drawstring component 4 to feed the bag opening of the product to be buckled into the middle hole of the end buckle. Then, a sensor signal controls the buckle-breaking component 5 to detach the buckle with the bag opening from the main body of the continuous buckle 100. Finally, the buckle-feeding component 3 replenishes a new buckle, preparing for the next work cycle. Thus, this invention, through the controller 6 coordinating the conveying component 2, packaging bag drawstring component 4, buckle-breaking component 5, and buckle-feeding component 3, achieves a fully automatic cyclical operation of "bag opening fed into the buckle hole → buckle cut → conveying the buckled product → automatic replenishment of a new buckle." This equipment not only significantly improves the automation level, operational accuracy, and production efficiency of the food packaging bag buckling process, but also effectively ensures food hygiene and safety and the stability of the packaging seal.

[0022] In another embodiment, see Figure 3 and Figure 4 As shown, a support frame 11 is mounted on the frame 1. The packaging bag drawstring assembly 4 includes a vertical plate 41 mounted on the support frame 11, an outer roller group 42 and an inner roller group 43 for clamping the bag opening, and a first power member mounted on the vertical plate 41 for driving the outer roller group 42 and the inner roller group 43 to rotate. The outer roller group 42 and the inner roller group 43 are arranged opposite to each other and form a gap in the horizontal direction that allows the tie to pass through. Thus, the first power member drives the outer roller group 42 and the inner roller group 43 to operate synchronously, and the two cooperate to clamp and transport the bag opening from the conveying assembly 2 from both the inside and outside. Since the tie is pre-placed in the gap between the outer roller group 42 and the inner roller group 43, when the outer roller group 42, the inner roller group 43 and the conveying assembly 2 work together to push the bag opening of the product forward as a whole, the front end of the bag opening will accurately abut into the tie at the end; as the pushing action continues, the bag opening is smoothly tied into the tie, completing the sealing.

[0023] In a specific embodiment, the outer roller assembly 42 includes an outer active conveying roller 421, a first outer driven upper pressure roller 422, a first synchronous belt 423 that synchronously connects the outer active conveying roller 421 and the first outer driven upper pressure roller 422, and a first outer driven lower pressure roller 424 that is tangentially arranged to the outer periphery of the first outer driven upper pressure roller 422; the inner roller assembly 43 includes an inner active conveying roller 431, a first inner driven upper pressure roller 432, and a first synchronous belt 423 that synchronously connects the inner active conveying roller 421 and the first inner driven upper pressure roller 432. The system includes a second synchronous belt 433 and a first inner driven lower roller 434 tangentially arranged to the outer periphery of the first inner driven upper roller 432. The first power component is a first motor 44, which is a precisely controllable servo motor. The outer active conveyor roller 421 and the inner active conveyor roller 431 are coaxially connected and connected to the power shaft of the first motor 44. The first outer driven upper roller 422 is coaxially connected to the first inner driven upper roller 432, and the first outer driven lower roller 424 is coaxially connected to the first inner driven lower roller 434. Thus, the outer side of the bag opening is clamped and conveyed by the cooperation of the first outer driven upper roller 422 and the first outer driven lower roller 424, while the inner side of the bag opening is clamped and conveyed by the cooperation of the first inner driven upper roller 432 and the first inner driven lower roller 434, thereby completing the clamping and conveying of both the inner and outer sides of the bag opening.

[0024] In a preferred embodiment, the outer roller group 42 further includes a second outer driven upper pressure roller 425, a second outer driven lower pressure roller 426 tangentially arranged to its outer periphery, and a third synchronous belt 427 that synchronously connects the first outer driven lower pressure roller 424 and the second outer driven lower pressure roller 426; the inner roller group 43 further includes a second inner driven upper pressure roller 435, a second inner driven lower pressure roller 436 tangentially arranged to its outer periphery, and a fourth synchronous belt 437 that synchronously connects the first inner driven lower pressure roller 434 and the second inner driven lower pressure roller 436, with the first outer driven upper pressure roller 422 and the second outer driven upper pressure roller 425 arranged side by side in the horizontal direction. Therefore, by adding a second outer driven upper pressure roller 425 and a corresponding second outer driven lower pressure roller 426 to the outer roller assembly 42, and connecting them via a third synchronous belt 427, the outer side of the bag opening can be clamped more evenly, improving conveying stability. Simultaneously, by adding a second inner driven upper pressure roller 435 and a corresponding second inner driven lower pressure roller 436 to the inner roller assembly 43, and connecting them via a fourth synchronous belt 437, the inner side of the bag opening can be clamped more evenly, thereby improving conveying stability. Figure 3As shown, guide posts 46 are provided at the front ends of the first outer driven lower pressure roller 424 and the first inner driven lower pressure roller 434, which facilitates the guidance of the bag opening of the product to be tied, so that the bag opening can smoothly enter the outer roller group 42 and the inner roller group 43 for clamping and conveying. More preferably, in order to maintain the tension of the synchronous belt and improve the transmission capacity, tensioning pulleys 45 are also provided on the outer sides of the first synchronous belt 423 and the second synchronous belt 433.

[0025] In another embodiment, see Figure 5 and Figure 6 As shown, the snap fastener assembly 5 is equipped with a protective cover 12, which includes a fixed plate 51 mounted on the support frame 11, a second power component mounted on the fixed plate 51, a first linear reciprocating mechanism driven by the second power component, and a pull block 53 driven by the first linear reciprocating mechanism to move horizontally. The horizontal position of the pull block 53 corresponds to the end snap fastener of the row of snap fasteners 100. Thus, by driving the pull block 53 to perform horizontal linear reciprocating motion through the first linear reciprocating mechanism, the product with the finished snap fastener is removed from the row of snap fasteners 100 by controlling the movement of the pull block 53, and then conveyed away by the conveying assembly 2.

[0026] Specifically, the second power component is a second motor 52, which is a servo motor capable of precise control. The first linear reciprocating mechanism includes a first crank 54 powered by the second motor 52, a first sliding column 55 connected to the outer end of the first crank 54, and a first sliding block 56 slidably connected to the first sliding column 55. A first guide rail 57 arranged horizontally is mounted on the fixed plate 51. The first sliding block 56 is slidably connected to the first guide rail 57. One end of the first sliding block 56 has a first oblong hole 561, through which the first sliding column 55 passes and slides. The other end of the first sliding block 56 is fixedly connected to the pull block 53. Thus, the first crank 54 drives the first sliding column 55 to slide in the first oblong hole 561 of the first sliding block 56, thereby driving the first sliding block 56 to slide on the first guide rail 57, and thus driving the pull block 53 to achieve linear reciprocating movement.

[0027] In another embodiment, participants Figure 7 As shown, the buckle feeding assembly 3 includes a third power member mounted on the fixed plate 51, and a second linear reciprocating mechanism driven by the third power member for intermittently conveying the row of buckles 100 downwards. Thus, the intermittent downward conveying of the row of buckles 100 is achieved by the second linear reciprocating mechanism.

[0028] In a specific implementation, the third power component is a third motor 31, which is also a servo motor. The second linear reciprocating mechanism includes a second crank 32 powered by the third motor 31, a second sliding column 33 connected to the outer end of the second crank 32, and a second sliding block 34 slidably connected to the second sliding column 33. A second guide rail 35 arranged vertically is mounted on the fixed plate 51. The second sliding block 34 is slidably connected to the second guide rail 35. One end of the second sliding block 34 has a second oblong hole 341. The second sliding column 33 passes through the second oblong hole 341 and can slide therein. A toggle member 36 for driving the buckle to move downward is fixedly connected to the second sliding block 34. The second crank 32 drives the second sliding column 33 to slide in the second oblong hole 341 of the second sliding block 34, which in turn drives the second sliding block 34 to slide on the second guide rail 35, thereby driving the toggle member 36 to perform linear reciprocating motion, completing the buckle replenishment action. More specifically, a vertical slot 511 is provided on the fixed plate 51, and the actuating member 36 is inclined by the spring 37 and its outer end passes through the slot 511 and abuts against the middle hole of the buckle, thereby realizing the feeding of the buckle through the actuating member 36.

[0029] To improve the conveying stability of the continuous row of buckles 100, the high-speed fully automatic buckle machine also includes a buckle roll placement mechanism 7 located above the buckle feeding assembly 3. The buckle roll placement mechanism 7 includes a bracket 71 and a rotatable turntable 72 mounted on the bracket 71. The continuous row of buckles 100 are wound onto the rotatable turntable 72 for easy buckle feeding.

[0030] The operating steps of the high-speed fully automatic buckle fastening machine of the present invention are as follows: The operator first places the product to be secured on the conveying assembly 2, with the bag opening facing the packaging bag drawstring assembly 4, and simultaneously places the bag opening on the guide post 46. The bag opening is synchronously clamped and conveyed by the outer active conveying roller 421 and the inner active conveying roller 431, accurately conveying the bag opening to the middle hole of the end buckle. Then, the pull block 53 of the buckle-breaking assembly 5 moves to release the buckle with the bag opening, and the conveying assembly 2 continues to convey the sealed product forward. Then, the operator controls the action of the actuating component 36 of the buckle-feeding assembly 3, which pulls the row of buckles 100 downward to prepare for the next buckling action.

[0031] The above descriptions are merely some embodiments of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are protected by the present invention.
