Description

Technical Field

[0001] The present application relates to the field of packaging machinery, and in particular to a stable bagging type automatic packaging machine. Background Art

[0002] An automatic packaging machine is a mechanical device that bags products after they are produced. It generally consists of four parts: a feeding mechanism, a conveying mechanism, a pushing mechanism, and a sealing mechanism, to replace manual labor to complete the continuous packaging operation.

[0003] The pushing mechanism often uses a suction cup or other negative pressure structure to cooperate with the pushing cylinder. The pushing mechanism pushes multiple products at a time. When pushing, first place the packaging bag horizontally on the operating table, let the suction cup suck the two sides of the packaging bag inlet, and drive the packaging bag inlet to open. The pushing cylinder then transports the product to a fixed point through the conveying mechanism and pushes it into the packaging bag, releasing the suction of the suction cup and allowing the packaging bag to enter the next sealing process.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: when the product is a multi-layer and soft material, such as a paper towel package or a sanitary napkin, a layer of soft packaging is already covered on the outside of the material. When pushing the material, the soft packaging between multiple products is prone to sliding, resulting in uneven discharge of the products in the packaging bag. Utility Model Content

A width adjustment component is provided between the two baffles to adapt to the size of the product to be packaged.

[0008] Optionally, the width adjustment assembly includes a servo motor, a lead screw and a movable block. The servo motor is fixed on the operating table, the lead screw is fixedly connected to the servo motor, and the servo motor drives the lead screw to rotate.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-3 This application is described in further detail.

[0024] The present invention discloses a stable bagging automatic packaging machine. The machine comprises a feeding mechanism, a conveying mechanism, a pushing mechanism, and a sealing mechanism. It uses a side-entry method to place multi-layered, flexible products into packaging bags. The machine operates as follows: the feeding mechanism simultaneously feeds multiple products, the conveying mechanism delivers the products to a fixed location, the pushing mechanism pushes the products at the fixed location into the bag, and the sealing mechanism heat-seals the bag's inlet.

[0025] Reference Figure 1 The pushing mechanism is located on the operating table 1 of the entire machine and includes a frame 3, a pushing cylinder 4, and a guide frame 5. The frame 3 is fixedly mounted horizontally on the operating table 1. The pushing cylinder 4 is located on the side of the frame 3 away from the packaging bag. The pushing cylinder 4 is fixedly connected to the operating table 1 and is arranged perpendicular to the frame 3. The guide frame 5 is located below the frame 3. A sliding component 31 and a width adjustment component 6 are provided between the guide frame 5 and the frame 3. The two ends of the guide frame 5 are aligned with the pushing cylinder 4 and the packaging bag, respectively. When pushing materials, the guide frame 5 is used to guide and limit the movement of multiple products, thereby reducing sliding between multiple products during pushing and improving the neatness of product arrangement in the packaging bag.

[0026] Reference Figure 1 and Figure 2 The guide frame 5 includes two vertically arranged baffles 51. Both baffles 51 are parallel to the direction of movement of the piston cylinder of the push cylinder 4. Horizontally arranged upper baffles 52 are provided on the top of both baffles 51. The two upper baffles 52 are respectively located at the side walls of the two baffles 51 that are close to each other. One end face of the upper baffle 52 close to the push cylinder 4 is flush with the baffle 51, and a gap is left between the other end face and the baffle 51, that is, the end face of the upper baffle 52 away from the push cylinder 4 is not flush with the baffle 51. The two baffles 51 are used to limit the sliding of the product in the horizontal direction, and the upper baffle 52 is used to limit the sliding of the product in the vertical direction. At the same time, the upper baffle 52 can also support the packaging bag to prevent the packaging bag from collapsing and affecting the pushing of the product. The provision of the gap can reduce the contact surface between the guide frame 5 and the packaging bag, thereby reducing scratches on the packaging bag.

[0027] In order to ensure that the product to be packaged can accurately enter the guide frame 5, an open plate 53 is fixedly provided at one end of the two baffles 51 close to the pushing cylinder 4, and the two open plates 53 are inclined in the direction away from each other; the inclined surface of the open plate 53 can squeeze the product to be packaged to slide into the guide frame 5.

[0028] Reference Figure 2 and Figure 3The sliding assembly 31 is fixedly arranged on the frame horizontally. In this embodiment, a motor, a slider and a track are matched to realize that the guide frame 5 slides and is inserted into the packaging bag; the width adjustment assembly 6 is located between the sliding assembly 31 and the guide frame 5 along the horizontal direction. A cross plate 311 is provided between the width adjustment assembly 6 and the sliding assembly 31. The top surface of the cross plate 311 is fixedly connected to the slider of the sliding assembly 31. The width adjustment assembly 6 includes a servo motor 61, a screw 62 and a movable block 63. The servo motor 61 is fixedly connected to the cross plate 311. Both ends of the screw 62 are fixedly connected to the cross plate 311 and rotate. The screw 62 is perpendicular to the movement direction of the piston rod of the pushing cylinder 4. The threads at both ends of the screw 62 are opposite. The movable block 63 is provided with two, The two movable blocks 63 are both sleeved on the outside of the two ends of the screw 62, and the two movable blocks 63 are respectively threadedly connected to the two ends of the screw 62; in order to prevent the movable block 63 from rotating and deviating during sliding, a guide rail 631 is provided between the movable block 63 and the cross plate 311. The guide rail 631 is parallel to the length direction of the screw 62, and the top of the guide rail 631 is fixedly connected to the cross plate 311. At the same time, the guide rail 631 and the two movable blocks 63 are slidably connected by means of protrusions and protruding grooves; at the same time, the two baffles 51 are respectively fixedly connected to the bottom of the two movable blocks 63, and a structure for adjusting the height of the baffle 51 can also be provided between the two baffles 51 and the two movable blocks 63, such as a combination of a plate with a strip groove and a nut thread locking.

[0029] In order to more conveniently adjust the size between the two baffles 51, the servo motor 61 is also connected to a sensor. The sensors are located on both sides of the product to be packaged, and the two sensors are located on the same straight line. The two sensors work together to accurately measure the width of the product to be packaged. The sensor and the servo motor 61 are electrically connected to a controller. The sensor sends the measured size signal to the controller, and the controller controls the servo motor 61 to rotate. The servo motor 61 drives the two movable blocks 63 to move closer or farther away synchronously along the direction of the screw 62. The movable block 63 slides along the guide rail 631 until the distance between the two baffles 51 is the same as the measured width size. The controller controls the servo motor 61 to stop rotating, thereby completing the adjustment of the width between the two baffles 51 and improving the automation level of the entire device; the stroke control of the servo motor can also be achieved by using an absolute encoder and a memory battery. When the main power supply of the equipment is cut off, the memory battery will automatically take over and provide power to the encoder to ensure that the absolute position information or parameter settings of the encoder are not lost.

[0030] When pushing is required, the distance between the two baffles 51 is adjusted according to the width of the product to be packaged by first utilizing the linkage between the sensor and the servo motor 61, and then the motor of the sliding assembly 31 is started, and the sliding assembly 31 is used to drive the entire guide frame 5 to move toward the packaging bag, and the end of the guide frame 5 away from the pushing cylinder 4 is inserted into the packaging bag, and then the pushing cylinder 4 is turned on, and the piston rod of the pushing cylinder 4 pushes multiple products to be packaged through the guide frame 5 into the packaging bag. During the pushing process, the two baffles 51 abut against the multiple products to be packaged, limiting the multiple products to be packaged, thereby reducing the probability of sliding against each other.

[0031] Reference Figure 1 and Figure 2 A counter 2 is fixed to the upper stop bar 52. It counts the number of products passing through the guide frame 5 to prevent inconsistent product quantities within the bag, which could affect sales. Because the products within the bag are stacked, the range of movement of each layer varies. Therefore, the counter 2 is electrically connected to the pusher cylinder 4. Both the counter 2 and the pusher cylinder 4 are also electrically connected to a controller. The counter 2 transmits the counted value to the controller, which controls the extension length of the pusher cylinder 4's piston rod, thereby controlling the pushing distance. As the counted value from the counter 2 increases, the extension length of the pusher cylinder 4's piston rod decreases proportionally until the counted value from the counter 2 reaches a preset value, at which point the counter 2 value returns to zero. The preset value is the total number of products within the bag. When the counter 2 clears, the extension length of the pusher cylinder 4's piston rod returns to its maximum length. This ensures that the packaged products are neatly arranged layer by layer within the bag, preventing damage to the bag caused by excessive extension of the pusher cylinder 4.

[0032] Reference Figure 1 and Figure 3 A guide wheel is provided between the guide frame 5 and the pushing cylinder 4. The guide wheel is vertically fixed on the operating table 1. There are two groups of guide wheels. The two groups of guide wheels are respectively on both sides of the product to be packaged. The distance between the two groups of guide wheels is slightly larger than the distance between the two baffles 51 in the guide frame 5, so as not to affect the movement of the open plate 53; the two groups of guide wheels can also be set to be position-adjustable.

[0033] When pushing the material, the guide wheels guide the moving direction of the product to be packaged; when the number of products in the packaging bag reaches the preset number, the piston rod of the pushing cylinder 4 is retracted, and the sliding assembly 31 is started at the same time, driving the guide frame 5 away from the packaging bag. At this time, the open plate 53 of the guide frame 5 is inserted into the two sets of guide wheels, but the guide wheels will not be affected.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
