Description

Technical Field

[0001] The utility model relates to the technical field of packaging box assembly machines, in particular to a feeding structure of a packaging box assembly machine. Background Art

[0002] my country's public patent, application number CN201922081394.9, mentions a packaging box assembly machine: "Outer box, inner box, first conveyor belt, second conveyor belt, clamping device and pressing device, the first conveyor belt is used to convey the outer box, and an installation station is provided on the first conveyor belt. Positioning mechanisms are provided around the installation station, and the positioning mechanism is used to fix the outer box on the installation station; the second conveyor belt is provided at an angle above the installation station, and the second conveyor belt is used to convey the inner box. The pressing device is provided directly above the installation station, and the pressing device is used to press the inner box into the outer box. The present application provides a packaging box assembly machine, which fixes the outer box on the first conveyor belt through the positioning mechanism, and the clamping device transports the inner box on the second conveyor belt to the top of the outer box. The pressing device is guided by the positioning device in the process of pressing down the inner box, which limits the displacement path of the pressing device, so that the pressing device can accurately press the inner box into the outer box, thereby realizing precise alignment of the inner box and the outer box, and saving the production cost of the product."

[0003] Through searching the patent technology such as the above, it is found that the inner box is transmitted through the second conveyor belt so that the inner box and the outer box are merged, that is, the inner box and the outer box are assembled to form a packaging box by loading the material through the second conveyor belt.

[0004] However, during our simulation, we discovered that this technology still has certain flaws. Since the inner box is transported via the second conveyor belt, a clamping device is required to move the inner box on the second conveyor belt to the top of the outer box after it reaches the designated position. This means that after the inner box reaches the designated position, the second conveyor belt needs to be stopped to facilitate the clamping device to clamp the inner box. This undoubtedly puts a great test on the stopping timing of the second conveyor belt and the stopping position of the inner box. The inner box may be transported too far or too close, making it difficult for the clamping device to clamp the inner box. In addition, when the inner box is transported by the second conveyor belt, since there is no limiting structure around it, it may be shaken during the transmission process and deviate from its position, making it difficult to be located between the two clamping devices, making it difficult for the clamping device to clamp the inner box. Therefore, how to achieve fast and stable loading (transferring inner boxes) is an urgent problem to be solved in this technical field. Utility Model Content

[0010] As a further solution of the present invention: limiting strips are fixed on both sides of the lifting plate, and the inner cavity of the sliding block is provided with limiting grooves for facilitating the placement and sliding of the limiting strips.

[0011] As a further solution of the present invention: the two clamping blocks have the same height, and a damping rubber plate is glued and fixed to one side of the two clamping blocks close to each other.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 , a feeding structure of a packaging box assembly machine, including a support platform 1, with slide rails 3 fixed on both sides of the support platform 1, and a driving structure for driving a slider 4 to slide longitudinally provided on the slide rail 3. The driving structure includes a motor, a screw rod, and a slide groove. The screw rod is placed in the slide groove and is connected to the power output shaft of the motor. The screw rod is threadedly sleeved on the bottom of the slider 4 and placed on the block in the slide groove. The motor drives the screw rod to rotate, and the rotation of the screw rod drives the block at the bottom of the slider 4 to slide in the slide groove, thereby realizing the movement of the slider 4 on the slide rail 3. A feeding conveyor belt 2 is provided on the inner side of the support platform 1; the two inner walls of the support platform 1 A limiting component 5 is arranged between them, and the limiting component 5 includes an intercepting plate 501 fixed between the two inner walls of the support platform 1, and two limiting plates 502 close to each other are fixed on the intercepting plate 501, and an inner box is provided between the two limiting plates 502 for limiting, and a guide plate 503 is fixed on the end of each limiting plate 502 away from the intercepting plate 501; each slide rail 3 is driven and connected to a slider 4, and one side of the slider 4 is internally slidably connected to a lifting plate 9 driven by a servo motor 7, and an electric telescopic rod 11 is installed on the side of the lifting plate 9, and a clamping block 12 is installed on the driving shaft of the electric telescopic rod 11.

[0024] See also Figure 1 and Figure 2 In this embodiment, the two guide plates 503 are both arranged obliquely, and the inclination direction of the guide plates 503 is from the feeding direction to the discharging direction of the loading conveyor belt 2.

[0025] Specifically, the two inclined guide plates 503 can guide the inner box to the middle of the feeding conveyor belt 2, so that the inner box is stably placed between the two limit plates 502 and is intercepted by the interception plate 501 to stop moving.

[0026] See also Figure 1 and Figure 2 In this embodiment, the intercepting plate 501 , the limiting plate 502 and the guide plate 503 have the same thickness, and the bottoms thereof are all in sliding contact with the surface of the feeding conveyor belt 2 .

[0027] Specifically, the limiting assembly 5 composed of the intercepting plate 501 , the limiting plate 502 and the guide plate 503 has no direct connection with the feeding conveyor belt 2 , so it will not affect the normal transmission movement of the feeding conveyor belt 2 .

[0028] See also Figure 1 and Figure 3 In this embodiment, a door-shaped support frame 6 is fixed to the top of the slider 4, and a servo motor 7 is installed on the top of the door-shaped support frame 6. The power output shaft of the servo motor 7 movably passes through the door-shaped support frame 6 and is fixed with a screw 8. The bottom thread of the screw 8 passes through the lifting plate 9 and is movably connected to the inner cavity of the slider 4; limit strips 10 are fixed on both sides of the lifting plate 9, and the inner cavity of the slider 4 is provided with a limit groove for facilitating the placement and sliding of the limit strip 10.

[0029] Specifically, when the screw 8 rotates, it can drive the lifting plate 9 to move. When the lifting plate 9 moves, it can be limited by the limit bar 10, so that the lifting plate 9 can only move in the vertical direction, thereby driving the electric telescopic rod 11 and the clamping block 12 on the electric telescopic rod 11 to move in the vertical direction.

[0030] See also Figure 3 and Figure 5 In this embodiment, the two clamping blocks 12 have the same height, and the sides of the two clamping blocks 12 close to each other are glued and fixed with damping rubber plates. The two clamping blocks 12 can be respectively attached and clamped on both sides of the inner box of the packaging box.

[0031] Specifically, there is a damping rubber plate on the clamping block 12, which can increase the friction with the side wall of the inner box, thereby reducing the risk of the inner box falling during transportation. The two clamping blocks 12 have the same height and can be clamped at the same height on both sides of the inner box to achieve clamping stability.

[0032] During use, the staff can place the inner box to be transported on the feeding conveyor belt 2, and the inner box is transported toward the two clamping blocks 12 through the feeding conveyor belt 2. Since the limiting component 5 is provided on the feeding conveyor belt 2, the inner box is guided by the two guide plates 503 during transportation and enters between the two limiting plates 502. The inner box is prevented from continuing to be transported forward by the intercepting plate 501. At this time, the position of the inner box is relatively fixed and is placed between the two clamping blocks 12.

[0033] Then the two electric telescopic rods 11 can be started, and the power output shaft of the electric telescopic rod 11 pushes the clamping block 12 close to the side wall of the inner box until the two clamping blocks 12 form a clamping state for the inner box, and then the two servo motors 7 can be started, and the power output shaft of the servo motor 7 drives the screw 8 to rotate, and the rotation of the screw 8 drives the lifting plate 9 to rise, and drives the electric telescopic rod 11 to rise, and drives the two clamping blocks 12 to lift the inner box so far, so that the bottom of the inner box passes the intercepting plate 501, and finally the slider 4 can slide on the slide rail 3, thereby driving the inner box away from the feeding conveyor belt 2 and transporting it to the next production component. From then on, the feeding (transporting the inner box) operation is completed.

[0034] When the two clamping blocks 12 retract the inner box through the retraction of the power output shaft of the electric telescopic rod 11, the slider 4 can return to the initial position (the initial position is above the two limit plates 502, that is, the position where the inner box is intercepted), and the inner box placed between the two limit plates 502 can be clamped and transported again, completing the cyclic loading (transferring the inner box) operation.

[0035] It should be noted that the loading conveyor belt 2 can choose not to stop working when transporting the inner box, that is, the loading conveyor belt 2 is always in operation. Since there is an interception plate 501 on the loading conveyor belt 2, the inner box can be intercepted on the loading conveyor belt 2, and the inner box will not fall from the loading conveyor belt 2, so it is only necessary to place the inner box regularly from the feeding direction of the loading conveyor belt 2.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
