DETAILED DESCRIPTION

[0029] Preferred embodiments of the present application will be described in more detail with reference to the drawings. Although the preferred embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to convey the scope of the present application to those skilled in the art.

[0030] In the production process of active probiotic powder, one of the existing production processes is that the packaging machine automatically packages the powder to form a bagged powder product, and the bagged product is usually placed in a packaging box for packaging and sales. The traditional packaging box packaging and sealing process is mostly completed manually by workers. The workers need to first flatten the top of the packaging box containing the active probiotic powder, then use a brush or other simple tool to apply glue, and finally manually seal the box cover. This manual operation mode has low efficiency and is difficult to meet the needs of large-scale production, and the labor cost is high. On the other hand, since the operation method of manual glue application varies from person to person, the uniformity of glue application cannot be guaranteed. Uneven glue application may result in insecure sealing of the packaging box, which may be easily opened during subsequent transportation and sales, affecting product sales.

[0031] Based on this, the present application provides a solid preparation packaging box sealing device.

[0032] Embodiment

[0033] As shown in Figures 1-5 The solid preparation packaging box sealing device provided by the embodiment includes:

[0034] A rack 1 is provided with a conveying line 3 on the rack 1;

[0035] The rack 1 is provided with a stand 2, and the stand 2 is provided with a sealing box mechanism 5, the sealing box mechanism 5 comprises a mounting frame 51, a first sealing box structure 53 and a second sealing box structure, the mounting frame 51 is arranged on the stand 2 in a lifting mode, the first sealing box structure 53 comprises two opposite pressure rods 531, the length direction of the pressure rod 531 is arranged along the conveying direction of the conveying line 3, the front end of the pressure rod 531 is provided with a guide opening 532, and the middle part of the pressure rod 531 forms a first sealing box position 533; the width of the guide opening 532 gradually decreases along the conveying direction of the conveying line 3.

[0036] The second sealing box structure comprises two opposite pressure wheels 54 and a driving structure 52, and the driving structure 52 drives the two pressure wheels to move along the conveying direction of the conveying line 3.

[0037] The mounting frame 51 is further provided with a glue roller 61, the glue roller 61 is arranged on one side of the pressure rod 531, the glue roller 61 is provided with a glue outlet, and the glue outlet is connected with a glue supply mechanism 6.

[0038] Specifically, the first sealing box structure 53 of the sealing box mechanism is used for pressing the long side of the packaging box. When the packaging box is sent to the lower part of the sealing box mechanism 5 and enters the first sealing box structure 53, the front end of the packaging box will first enter the guide opening 532 at the front end of the pressure rod 531, and the guide opening 532 adopts a unique tapered structure, and the width of the guide opening 532 gradually decreases along the conveying direction of the conveying line 3. This provides a precise “navigation channel” for the packaging box, guiding the packaging box to smoothly and accurately enter the first sealing box position 533. Moreover, in the movement process of the packaging box, the long side of the packaging box is pressed down by the pressure rod 531, so that the long side of the packaging box is gradually attached to the packaging box.

[0039] The glue roller 61 is arranged on one side of the pressure rod 531, and the glue outlet of the glue roller 61 is connected with the external glue supply mechanism 6 through a special pipeline. The glue supply mechanism 6 can accurately control the supply flow and pressure of the glue according to the preset program and the actual production demand. When the packaging box passes under the glue roller 61 at a constant speed, the glue roller 61 is driven to rotate in connection with the surface of the packaging box, the glue flows out from the glue outlet, and thus the automatic glue coating is completed. By controlling the operation parameters of the glue supply mechanism 6, the number of glue coating can be adjusted.

[0040] The above-mentioned solid preparation packaging box sealing device, during use, utilizes the guide opening 532 to smoothly enter the first box pressing position 533. At the first box pressing position 533, the pressing rod 531 preliminarily flattens the top of the packaging box, ensuring the top to be flat, laying a foundation for subsequent glue application and box sealing operations. When the packaging box passes below the glue application roller 61, the glue application roller 61 uniformly applies glue to the part of the top of the packaging box that needs to be sealed, and the width and thickness of the glue application can be effectively controlled, avoiding the problem of too much or too little glue that may occur during manual glue application. After glue application is completed, the second box sealing structure presses the short side of the packaging box, so that the short side and the long side of the packaging box are tightly pressed together, completing the box sealing operation. The entire box sealing process is cooperated by the conveying line 3, the box sealing mechanism 5 and the like, realizing automatic operation. Compared with the traditional manual box sealing method, the time and steps of manual operation are greatly reduced. And the cooperation of the glue application roller 61 and the glue supply mechanism 6 realizes uniform glue application, avoiding the problem of poor sealing caused by uneven glue application, so as to ensure the box sealing quality of the packaging box.

[0041] Further, the glue application roller 61 is provided with two on the mounting frame 51, and the length direction of the two glue application rollers 61 is perpendicular to the length direction of the pressing rod 531. A plurality of glue outlets are provided on each glue application roller 61.

[0042] The length direction of the two glue application rollers 61 is perpendicular to the length direction of the pressing rod 531, and a plurality of glue outlets are distributed on each glue application roller 61. These glue outlets are closely connected with the external glue supply mechanism 6 through pipelines. The glue supply mechanism 6 can accurately control the supply flow and pressure of the glue. When the packaging box passes below the glue application roller 61 at a uniform speed, the two glue application rollers 61 rotate under the driving of the packaging box, and the plurality of glue outlets work simultaneously to uniformly apply an appropriate amount of glue to the part of the top of the packaging box that needs to be sealed. Since the double glue application roller 61 design is adopted, the two sides of the packaging box can be glued, and by controlling the operating power of the glue supply mechanism 6, the width of the glue application can be more accurately adjusted, which can effectively improve the stability and consistency of the glue application quality.

[0043] Specifically, the glue supply mechanism 6 includes a liquid storage tank 64, a pressure pump 63 and a control valve 62. The liquid storage tank 64 is connected with the two glue application rollers 61 through communication pipes 65. The pressure pump 63 and the control valve 62 are arranged on the communication pipes 65, and the control valve 62 is arranged downstream of the pressure pump 63 along the flow direction of the medium.

[0044] In use, when the packaging box passes under the glue roller 61, the operator sets the corresponding parameters in the control system according to the size and sealing requirements of the packaging box. The pressure pump 63 operates at the set power to deliver glue at a stable pressure to the communication pipe 65. The control valve 62 accurately adjusts the opening degree according to the preset flow value to ensure that the appropriate amount of glue flows out uniformly from each glue outlet. The two glue rollers 61 rotate synchronously under the drive of the motor to evenly apply glue to the top of the packaging box at the sealing position, achieving precise control of glue application.

[0045] In a specific embodiment, the stand 2 includes a crossbar 22 and two oppositely arranged vertical bars 21, the crossbar 22 being connected between the two vertical bars 21, a vertically arranged mounting slot being arranged in each vertical bar 21, and a rotatable screw rod 211 being arranged in the mounting slot;

[0046] The screw rod 211 is provided with a mounting block 212, the mounting block 212 being threadedly connected with the screw rod 211, the mounting bracket 51 being fixed on the mounting block 212, and a handle 221 being fixedly arranged at the top of the screw rod 211.

[0047] The screw rod 211-mounting block 212 structure on the stand 2 makes it convenient to adjust the height of the mounting bracket 51. By rotating the handle 221, the operator can quickly and accurately adjust the height of the mounting bracket 51 to adapt to packaging boxes of different height specifications. This enables the sealing box device to quickly switch between production of different products without the need for complex equipment adjustment or replacement, greatly improving the flexibility and adaptability of the production line and meeting diverse production needs. The adjustable height of the mounting bracket 51 ensures that the relative position between the sealing box mechanism 5 and the packaging box is always in the best state. Whether the packaging box is short or tall, it can be pressed, glued, and sealed at the appropriate position. This helps to ensure that the sealing quality of each packaging box is stable and consistent, avoiding problems such as uneven pressing, inaccurate glue application position, or insecure sealing due to inappropriate height, and improving the overall packaging quality of the product.

[0048] Further, the drive structure 52 includes a connecting rod 523, a crank 522, and a drive motor 521, the connecting rod 523 being arranged on the mounting bracket 51, the connecting rod 523 being provided with the rotatable crank 522, the crank 522 including a first end and a second end, the second end of the crank 522 being located below the mounting bracket 51, and the pressing wheel being arranged on the second end of the crank 522;

[0049] The drive motor 521 is fixed on the mounting bracket 51, and the output end of the drive motor 521 is connected with the first end of the crank 522.

[0050] During the pressing process, when the glued packaging box moves under the pressing wheel, the driving motor 521 starts to drive the first end of the crank 522 to make a circular motion. Since the crank 522 can rotate around the connecting rod 523, the second end of the crank 522 will make a reciprocating swing with the circular motion of the first end. The pressing wheel installed at the second end of the crank 522 also makes a reciprocating motion, first pressing the short side of the packaging box, and using the rolling and pressure of the pressing wheel to make the short side tightly fit; then, with the continuous conveying of the packaging box, the pressing wheel presses the short side and the long side of the packaging box, and finally firmly seals the short side and the long side of the packaging box together. During the whole process, the speed and torque of the driving motor 521 can be adjusted according to the material and size of the packaging box, etc., to ensure that the pressing force and speed of the pressing wheel are moderate.

[0051] Further, the surface of the pressing wheel is coated with rubber.

[0052] The rubber has good elasticity, which can better adapt to the slight unevenness of the surface of the packaging box during the pressing of the packaging box by the pressing wheel, fill the gaps, and make the glue play a more full role, thereby enhancing the sealing of the packaging box. The rubber material is soft, and will not cause scratches, indentations or damage to the surface of the packaging box during the pressing process, as hard materials such as metal do. This not only protects the appearance integrity of the packaging box, but also avoids affecting the display and sales of the product due to damage to the packaging box, and improves the overall quality image of the product.

[0053] Further, two limiting rods 4 are arranged above the conveying line 3, and the limiting rods 4 are slidably arranged on the rack 1.

[0054] The limiting rods 4 are used for limiting the packaging box, and the positions of the limiting rods 4 are adjustable, which can meet the limiting of packaging boxes of different sizes.

[0055] More preferably, the conveying line 3 has an inlet end, and a guide wheel 11 is arranged between the inlet end and the rack 1, and the guide wheel 11 is rotatably arranged on the rack 1.

[0056] The guide wheel 11 has a guiding and correcting effect on the packaging box, so that the packaging box can enter the conveying line 3 more smoothly, reducing the collision and friction between the packaging box and the conveying line 3. This not only reduces the wear of the conveying line 3 and prolongs the service life of the conveying line 3, but also reduces the production interruption and maintenance cost caused by the failure of the conveying line 3.

[0057] In addition, it should be noted that the use of the words "first", "second", etc. to define parts only facilitates the differentiation of the corresponding parts, and the above words have no special meaning unless otherwise stated, so they cannot be understood as limiting the scope of protection of the present application.

[0058] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
