DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-4 A cosmetic packaging box sealing machine in this embodiment includes a gear rod 1 and a pressing assembly 2 installed under the gear rod 1.

[0032] It should be noted that a sealing plate assembly 3 is installed on the outer side of the gear rod 1 , and a pressing plate assembly 4 is arranged on the inner side of the sealing plate assembly 3 .

[0033] Among them, the pressure plate assembly 4 includes a cross bar and a pressure plate rotatably arranged at one end of the cross bar, a groove is arranged on the pressure plate, and the cross bar is rotatably arranged inside the groove. After the pressure plate is rotated to a horizontal position, the cross bar is hidden in the groove. The pressure plate is an isosceles trapezoid, and the thickness at the bottom edge is greater than the thickness at the top edge. The top cross-section of the pressure plate is smaller, so the weight at the top is lighter, the weight at the bottom is heavier, and the center of gravity is concentrated at the bottom. During movement, the pressure plate remains in an upright state, and when it contacts the side of the box, the bottom is blocked, and then rotates around the cross bar, thereby pressing the inner panel of the box to close. The width and depth of the groove on the back of the pressure plate provide sufficient space to accommodate the cross bar. When the pressure plate is rotated to a horizontal state, the cross bar is hidden in the groove, and the outer panel of the carton is erected through the closing plate assembly 3.

[0034] In addition, the sealing plate assembly 3 includes support rods symmetrically arranged on both sides of the pressure plate assembly 4 and sealing plates fixedly connected to the support rods, and the sealing plate includes a first limiting portion arranged at the front end to push the outer panel of the box to stand upright and a second limiting portion arranged at the rear end to press the outer panel of the box to stand upright and close; the first limiting portion has a small front end section, a large rear end section, and a top surface that is an arc-shaped block convex upward; the second limiting portion has a small front end section, a large rear end section, and a top surface that is an arc-shaped block concave downward, and the front end of the second limiting portion is fixedly connected to the top of the rear end of the first limiting portion. When sealing the box, the first limiting portion at the front end first contacts the side of the box body, and then guides the lying outer panel of the box upward through the first limiting portion to make it stand upright, and then closes the outer panel of the box in the upright state to the inside through the second limiting portion, and finally covers the top of the inner panel of the box, and then the pressing plate and the sealing plate can be pulled out together by pulling them out, thereby realizing the sealing operation. The inner panel of the box can be pressed inward by the pressure plate assembly 4 to be pressed to close.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the clamping assembly 2 includes a fixed box 201 fixedly installed at the bottom of the gear rod 1, a first servo motor 202 fixedly installed on the right side of the fixed box 201, a rotating rod 203 fixedly installed on the output shaft of the first servo motor 202 and one end of which passes through and extends into the fixed box 201, two threaded sleeves 204 rotatably connected to the top wall of the fixed box 201 and passing through its bottom, a worm gear assembly 205 installed on the outside of the two threaded sleeves 204 and capable of driving them to rotate, a movable screw 206 threadedly connected to the inside of the two threaded sleeves 204, a concave block 207 fixedly installed at the bottom of the two movable screws 206, and a translation assembly 208 installed inside the concave block 207.

[0036] The left side of the rotating rod 203 is rotatably connected to the left side wall of the inner cavity of the fixed box 201 to ensure the stability of the rotation of the rotating rod 203. When the first servo motor 202 is started, the output shaft of the first servo motor 202 drives the rotating rod 203 to rotate.

[0037] like Figure 2 and Figure 3 As shown, in this embodiment, the worm gear assembly 205 includes a worm fixedly mounted on the outside of the rotating rod 203, and a worm wheel fixedly mounted on the outside of two threaded sleeves 204 and meshing with the worm. When the rotating rod 203 rotates, the rotating rod 203 drives the worm to rotate, and the worm drives the two worm wheels meshing with it to rotate, and the two worm wheels respectively drive the two threaded sleeves 204 to rotate. Through the worm and the two worm wheels, the rotating rod 203 can drive the two threaded sleeves 204 to rotate respectively.

[0038] The two threaded sleeves 204 are respectively located on the front and back sides of the rotating rod 203 , ensuring that the rotation directions of the two threaded sleeves 204 are opposite and the rotation amplitudes of the two threaded sleeves 204 remain consistent.

[0039] It should be noted that the bottom of the fixed box 201 is provided with two rotation holes penetrating therein, and the two threaded sleeves 204 are respectively rotatably connected to the inside of the two rotation holes, and the rotation stability of the two threaded sleeves 204 can be respectively ensured through the two rotation holes.

[0040] In addition, because the bottoms of the two movable screws 206 are fixedly connected to the top of the concave block 207, the two movable screws 206 will not rotate. At the same time, because the outer threads of the two movable screws 206 are in opposite directions, when the two threaded sleeves 204 rotate, under the action of the thread thrust, the two threaded sleeves 204 will respectively drive the two movable screws 206 to move downward, the two movable screws 206 will drive the concave block 207 to move downward, and the concave block 207 will drive the translation assembly 208 to move downward.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the translation assembly 208 includes a second servo motor 2081 fixedly mounted on the front side of the concave block 207, a fixed screw 2082 fixedly mounted on the output shaft of the second servo motor 2081 and with one end passing through and extending into the interior of the concave block 207, a translation block 2083 threadedly connected to the outside of the fixed screw 2082, a sliding assembly 2084 arranged on the top of the translation block 2083 and limiting it, and a rolling assembly 2085 installed on the bottom of the translation block 2083.

[0042] Among them, the left side of the fixed screw 2082 is rotatably connected to the left side wall of the inner cavity of the concave block 207 to ensure the stability of the rotation of the fixed screw 2082. When the second servo motor 2081 is started alternately forward and reverse, the output shaft of the second servo motor 2081 will drive the fixed screw 2082 to rotate alternately forward and reverse.

[0043] It should be noted that the sliding assembly 2084 includes a sliding limit block fixedly installed on the top of the translation block 2083, and a sliding limit groove opened on the inner top wall of the concave block 207 and slidably connected to the sliding limit block. The translation block 2083 can be limited by the sliding limit block and the sliding limit groove to prevent the translation block 2083 from rotating. When the fixed screw 2082 rotates alternately forward and reverse, under the action of the threaded thrust, the fixed screw 2082 will drive the translation block 2083 to move back and forth.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, the rolling assembly 2085 includes two ear plates fixedly installed on the bottom of the translation block 2083 and a pressing roller rotatably connected between the opposite sides of the two ear plates. When the translation block 2083 moves back and forth, the translation block 2083 will drive the pressing roller below it to move back and forth, and when the pressing roller moves, it will roll and press the tape and the top of the carton, so that the carton and the tape are more tightly adhered.

[0045] The working principle of the above embodiment is:

[0046] When the cosmetic packaging sealing machine is in use, the carton is placed inside the sealing machine, the outer plate of the carton is erected by the sealing plate assembly 3, the inner plate of the box can be pressed inward by the pressing plate assembly 4, pressed to close it, and finally glued with tape. After gluing the tape, the first servo motor 202 is started first, the output shaft of the first servo motor 202 drives the rotating rod 203 to rotate, the rotating rod 203 drives the worm to rotate, the worm drives two worm wheels meshing with it to rotate, the two worm wheels respectively drive the two threaded sleeves 204 to rotate, under the action of the thread thrust, the two threaded sleeves 204 respectively drive the two movable screws 206 to move downward, the two movable screws 206 drive the concave block 207 to move downward, the concave block 207 drives the translation assembly 208 to move downward, until the outer side of the pressing roller abuts against the top of the carton and the top of the tape;

[0047] Then the second servo motor 2081 is started alternately in forward and reverse directions, and the output shaft of the second servo motor 2081 drives the fixed screw 2082 to rotate alternately in forward and reverse directions. Under the action of the thread thrust, the fixed screw 2082 drives the translation block 2083 to move back and forth, and the translation block 2083 drives the pressing roller below it to move back and forth;

[0048] When the pressing roller moves, it rolls and presses the tape and the top of the carton, making the carton and the tape stick more tightly, increasing the bonding effect between the tape and the carton, and improving the sealing effect of the device.
