Abstract
Description
Technical Field
[0001] The utility model belongs to the field of packaging box conveying, and in particular relates to a packaging box conveying and lifting device. Background Art
[0002] After the chrysanthemums are produced and processed, they need to be bagged and put into boxes. The boxes need to go through multiple processes such as sealing and labeling before they can be stacked on wooden boards in order. Finally, the stacked boxes are put into storage. In actual situations, if there is a height difference between adjacent processing positions, then a conveying and lifting device is needed to transport and lift the boxes.
[0003] In the production process, most of the packaging boxes are directly pushed into the lifting rack, and then the lifting rack rises to a suitable height to lift the packaging boxes. However, during the pushing process, the packaging boxes are easily pushed out of the lifting rack, which affects the subsequent operations. Then there are some that limit the packaging boxes by driving the limit plate on the lifting rack with a cylinder, but this is too simple and cannot guarantee that the packaging boxes can be prevented from falling off the lifting rack every time. Utility Model Content
[0004] In view of the above problems, the purpose of the present invention is to provide a packaging box conveying and lifting device, aiming to solve the problem that the packaging box is easily separated from the lifting frame when the packaging box is conveyed and lifted by the packaging box conveying and lifting device.
[0005] The utility model adopts the following technical solutions:
[0006] The packaging box conveying and lifting device includes a frame, a pushing frame which can slide forward and backward is provided at the front end of the frame, a lifting frame is provided at the rear end of the frame, a loading plate which can slide forward and backward is provided inside the lifting frame, a loading platform which is arranged adjacent to the lifting frame is provided inside the frame, and the lifting frame is provided with a limiting mechanism and a clamping mechanism from the front and back respectively, the limiting mechanism includes a limiting frame installed on the lifting frame, a rotating shaft is rotatably provided above the limiting frame, a pair of driving gears is provided on the rotating shaft, a pair of rotating gears are provided on both sides of the limiting frame, a matching connecting chain is sleeved between the driving gear and the rotating gear on the same side, a limiting plate is provided between the two connecting chains, and a driving motor for driving any rotating gear to rotate is also provided on the frame.
[0007] Furthermore, connecting seats are respectively provided on both sides of the lifting frame, and the lifting frame is slidably installed in the frame through the connecting seats.

[0008] Furthermore, counterweight boxes are slidably provided on both sides of the frame, and the lifting mechanism includes a pair of lifting gears rotatably installed on the top of the frame, a lifting chain is sleeved on the lifting gears, one end of the lifting chain is connected to the connecting seat, and the other end is connected to the counterweight box, and a bidirectional motor is also provided on the top of the frame for driving the two lifting gears to rotate simultaneously.
[0009] Furthermore, the clamping mechanism includes an internal threaded seat and a clamping motor respectively installed on both sides of the lifting frame, a threaded clamping rod is provided in the internal threaded seat, a driven gear is provided in the middle of the threaded clamping rod, and a clamping plate is provided at the end, a driving gear is provided on the driving shaft of the clamping motor, and a clamping chain is sleeved between the driving gear and the driven gear.

At the same time, the pushing frame slides forward to the original position to wait for pushing the next packaging box, and the limiting plate is reset at that time. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0018] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.
[0019] Combination Figure 1-4 As shown, the packaging box conveying and lifting device includes a frame 1, a front end of the frame 1 is provided with a pushing frame 2 which can slide forward and backward, a rear end of the frame 1 is provided with a lifting frame 3, a carrier plate 4 which can slide forward and backward is provided in the lifting frame 3, a carrier platform 5 arranged adjacent to the lifting frame 3 is provided in the frame 1, and a limiting mechanism and a clamping mechanism are respectively provided at the front and rear of the lifting frame 3, the limiting mechanism includes a limiting frame 6 installed on the lifting frame, a rotating shaft 7 is rotatably provided above the limiting frame 6, a pair of driving gears 8 are provided on the rotating shaft 7, a pair of rotating gears 9 are provided on both sides of the limiting frame 6, a matching connecting chain 10 is sleeved between the driving gear 8 and the rotating gear 9 on the same side, a limiting plate 11 is provided between the two connecting chains 10, and a driving motor 12 for driving any rotating gear to rotate is also provided on the frame 1.
[0020] In the present device, the front end side wall of the frame is provided with an opening, into which a transfer platform (not shown) is inserted and placed, and the transfer platform is arranged at a right angle to the carrier.
[0021] After the chrysanthemums are produced and processed, they need to be bagged and put into packaging boxes. The packaging boxes need to go through multiple processes such as sealing and labeling before they can be stacked on wooden boards in order. Finally, the stacked packaging boxes are put into storage. In actual situations, if there is a height difference between adjacent processing positions, this device can be used to transport and lift the packaging boxes.
[0022] Specifically, after the packaging box has been processed in the previous process and is transported to the carrier under the action of the conveyor, the push frame slides backward and pushes the packaging box onto the carrier. The limit mechanism can prevent the push frame from pushing the packaging box off the carrier and dropping it to the ground. Figure 1-2 As shown, the drive motor is installed on the right side of the frame to drive one of the rotating gears on the right side. After the packaging box is pushed onto the carrier, the drive motor drives the corresponding rotating gear to rotate, and the lower shaft rotates under the linkage of the connecting chain on the same side, and the other connecting chain rotates synchronously. At this time, the limit plate moves upward to cancel the limit, and after the carrier moves backward to the clamping position, the packaging box is clamped by the clamping mechanism. At the same time, the push frame slides forward to the original position to wait for the next packaging box to be pushed, and the limit plate is reset at that time.
[0023] As a preferred structure, Figure 4, connecting seats 13 are respectively provided on both sides of the lifting frame 3, and the lifting frame 13 is slidably installed in the frame 1 through the connecting seats 13. Tracks 14 are respectively formed on both sides of the frame 1. A pair of limiting wheels 15 and a sliding wheel 16 are both provided outwardly at the upper and lower positions of the connecting seats 13. The track 14 passes through the two pairs of limiting wheels 15 on the same side, and the sliding wheel 16 is always in contact with the track. A lifting mechanism for driving the lifting frame 3 to move up and down is provided on the top of the frame 1.
[0024] In this structure, the side walls of the lifting frame are slidably connected to the inner side of the frame through a connecting seat. When the lifting mechanism drives the lifting frame to move up and down, the two sets of limiting wheels and sliding wheels will slide along the height direction of the same side track. The two limiting wheels and sliding wheels of the same set are distributed in a triangular shape. When the lifting frame moves up and down, the limiting wheels and sliding wheels play a role of limiting and sliding, so as to prevent the lifting frame from shaking during the movement and improve the stability of the lifting frame during the up and down movement.
[0025] A counterweight box 17 is slidably provided on both sides of the frame 1, and the lifting mechanism includes a pair of lifting gears 18 rotatably installed on the top of the frame, and a lifting chain 19 is sleeved on the lifting gears 18. One end of the lifting chain 19 is connected to the connecting seat 13, and the other end is connected to the counterweight box 17. A bidirectional motor 20 is also provided on the top of the frame 1 for driving the two lifting gears 18 to rotate simultaneously.
[0026] When the packaging box is clamped by the clamping mechanism, the lifting mechanism drives the lifting frame to move upward. Specifically, the bidirectional motor drives the two lifting gears to rotate clockwise at the same time, and the two lifting chains also rotate clockwise, pulling the connecting seat on the same side to slide upward along the height direction of the frame, and the lifting frame moves upward. At the same time, the two counterweight boxes slide downward until the packaging box is lifted to the specified height. The clamping mechanism cancels the clamping of the packaging box, and the packaging box is transferred to the next process processing position for the corresponding process processing.
[0027] like Figure 3-4 The bottom of the frame 1 is provided with a support seat 21 corresponding to the connecting seat 13. After the packaging box is transferred to the next process processing position, the bidirectional motor is reversed, and the lifting frame moves downward until it contacts the support seat.
[0028] Further as a preferred structure, Figure 3 The clamping mechanism includes an internal thread seat (blocked in the figure) and a clamping motor 23 respectively installed on both sides of the lifting frame 3. A threaded clamping rod 24 is provided in the internal thread seat. A driven gear is provided in the middle of the threaded clamping rod 24 and a clamping plate 26 is provided at the end. A driving gear 25 is provided on the driving shaft of the clamping motor 23, and a clamping chain is sleeved between the driving gear and the driven gear.
[0029] A pair of sliding sleeves are also provided on both sides of the lifting frame 3, and a sliding rod 29 is inserted into the sliding sleeves. The ends of the two sliding rods are connected to the clamping plate 26. The threaded clamping rod is located between the two sliding rods. When the clamping mechanism is needed to clamp the packaging box, the two clamping motors are driven at the same time, the driving gear rotates, and under the linkage of the clamping chain, the threaded clamping rod moves toward the packaging box until the clamping plate clamps the packaging box. After the packaging box is clamped, the driving motor is reversed until the limit plate is reset.
[0030] In this device, a pair of belt transmission mechanisms are respectively arranged in the frame and the lifting frame, and the two pairs of belt transmission mechanisms drive the push frame and the carrier plate to slide forward and backward. The belt transmission mechanisms are all prior art, so they are not described here.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
