Description

Technical Field

[0001] This utility model relates to the field of transfer devices, specifically a transfer device for the production of packaging cartons. Background Technology

[0002] In the large-scale production of packaging cartons, the transfer of folded cartons is a crucial process connecting production steps (such as printing, die-cutting, and forming) and warehousing. Its transfer efficiency and stability directly affect the overall production rhythm and the quality of the finished cartons. To address the problems of low efficiency and easy tipping of cartons during manual transfer, existing technologies have developed transfer devices for packaging carton production. These devices use mechanical structures to compact and position folded cartons and facilitate their movement, thus meeting basic transfer needs to a certain extent. A Chinese utility model patent (publication number: CN222310665U) discloses a transfer device for carton production. This device uses a pneumatic pusher with an extended output shaft. The pneumatic pusher lowers a support frame via a fixed plate, and the support frame lowers a cylinder via a fixed ring. A piston plate on the inner wall of the cylinder lowers a pressure plate via a pressure rod, compacting the cartons and clamping them to prevent tipping during rotation. This allows for higher stacking of cartons, increasing the number of cartons transferred at once and improving the transfer speed.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, when transferring small-sized folded cartons, the compression disc driven by the fixed cylinder can only act on a local area of ​​the carton (such as the edge) or even have incomplete contact, making it difficult to effectively compact the central area of ​​the carton. This causes the carton to easily shift its center and tip over during the transfer process. The cylinder is fixedly connected to the support frame through a fixed ring, and the spatial position of the cylinder cannot be adaptively adjusted according to the carton specifications, which reduces the applicability of the device. Therefore, in view of the above situation, a transfer device for packaging carton production is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a transfer device for producing packaging cartons. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A transfer device for producing packaging cartons includes a transfer trolley 1, a lifting bracket is provided at one end of the top of the transfer trolley 1, a mounting base 2 is fixed at one end of the lifting bracket, and a first cylinder 3 is fixed at the top of the mounting base 2.

[0026] Among them, the transfer trolley 1 serves as the overall load-bearing foundation of the device. It is made of high-strength carbon steel and welded together. All four corners of the bottom are fixed with universal guide wheels with brake function by bolts, which facilitates flexible steering and fixed-point locking. The top of the trolley is covered with anti-slip rubber pads with diamond-shaped anti-slip patterns on the surface of the rubber pads, which can increase the friction between the folded carton and the top surface of the trolley and prevent the carton from sliding during the initial stacking. A push-pull rod is welded to one side of the trolley and covered with an anti-slip plastic sleeve for the operator to hold and push and pull, improving the convenience of transfer operation.

[0027] The telescopic end of the first cylinder 3 passes downward through the mounting base 2 and is fixed to the mounting bracket 4. The mounting bracket 4 is equipped with a drive mechanism 5. The bottom of the four side walls of the mounting bracket 4 are all horizontally fixed with a horizontal plate 6. A sliding groove 60 is opened on the horizontal plate 6. A sliding seat 61 slides on the sliding groove 60. One end of the drive mechanism 5 is hinged to the top of the sliding seat 61. When the drive mechanism 5 works, it drives the sliding seat 61 to move horizontally along the direction of the sliding groove 60. A fixing frame 62 is fixed to the bottom of the sliding seat 61. A second cylinder 7 is fixed on the fixing frame 62. A pressure plate 70 is fixed downward at the telescopic end of the second cylinder 7.

[0028] The bottom of the pressure plate 70 is covered with a silicone pad. The surface of the silicone pad has tiny bumps, which can increase the friction with the surface of the carton and prevent the pressure plate 70 from directly contacting the carton and causing scratches. The inlet and outlet of the second cylinder 7 are connected to a throttle valve, which can adjust the compaction speed and pressure of the pressure plate 70 to adapt to cartons and cardboard of different strengths.

[0029] Reference Figure 1 and Figure 2The top of the mounting base 2 has a through hole, and the telescopic end of the first cylinder 3 passes through the through hole. The inlet and outlet ports of the first cylinder 3 are connected to throttle valves, which can adjust the telescopic speed and prevent the mounting frame 4 from falling too fast and causing the pressure plate 70 to hit the carton.

[0030] Reference Figure 1 and Figure 4 The mounting bracket 4 has an inner cavity 40 inside. The four side walls of the mounting bracket 4 are provided with rectangular grooves 41 that communicate with the inner cavity 40. The bottom of the mounting bracket 4 is provided with a round hole 42.

[0031] Reference Figure 2 and Figure 3 The drive mechanism 5 includes a threaded rod 50, one end of which rotates on the top surface of the inner cavity 40. Specifically, the top of the threaded rod 50 is connected to the bearing seat on the top surface of the inner cavity 40 via a bearing. A connecting shaft is fixed at the bottom of the threaded rod 50, and the connecting shaft is clearance-fitted with the round hole 42. A rotating handle 51 is fixed at the end that passes through the round hole 42. A threaded cylinder 52 is threadedly fitted on the threaded rod 50. The surface of the threaded section of the threaded rod 50 is coated with anti-rust grease to improve the smoothness of movement of the threaded cylinder 52 and the service life of the thread. Connecting rods 53 are hinged on the threaded cylinder 52. There are four connecting rods 53, which pass through the corresponding rectangular slots 41 and are hinged to the sliding seat 61.

[0032] Among them, the wall of the round hole 42 is fixed with a deep groove ball bearing through the bearing seat, and the connecting shaft passes through the inner ring of the bearing to ensure that the threaded rod 50 rotates smoothly without jamming.

[0033] The rotating handle 51 has anti-slip textured edges for easy gripping and rotation by operators, and can be replaced with an electric drive component (such as a micro motor) to achieve automated adjustment as needed.

[0034] The inner wall of the threaded cylinder 52 is provided with an internal thread that matches the threaded rod 50, and four ear plates are uniformly welded to the outer wall. Each ear plate is hinged to a connecting rod 53 by a pin.

[0035] Reference Figure 2 and Figure 3 The fixing bracket 62 is L-shaped and has a through hole. The telescopic end of the second cylinder 7 extends downward through the through hole.

[0036] Reference Figure 3 The connecting rod 53 includes a first rod body, one end of which is hinged to the threaded cylinder 52, and the other end is rotatably connected to a second rod body, one end of which is hinged to the sliding seat 61.

[0037] Reference Figure 1, the lifting bracket includes columns 8 fixed at both ends of the top of the transfer cart 1. The columns 8 are in a "C" shape, and lifting rods 80 are slidably fitted on the columns 8. A triangular bracket 81 is fixedly connected to the tops of the two lifting rods 80. One end of the triangular bracket 81 is fixed to the mounting seat 2. A connecting rod 82 is fixed between the two lifting rods 80 to form a horizontal connection to ensure the synchronous lifting of the two lifting rods 80. One end of the top of the transfer cart 1 is fixed with a baffle 9. A support plate is fixed on one side of the baffle 9, and a third cylinder 90 is fixed on the support plate. The telescopic end of the third cylinder 90 is fixed to the bottom of the connecting rod 82.

[0038] Working principle: During use, according to the specifications of the cardboard boxes to be transferred, adjust the positions of the four second cylinders 7 by rotating the handle 51:

[0039] Operate and rotate the handle 51 to drive the threaded rod 50 to rotate. Under the action of thread fitting, the threaded barrel 52 moves in the vertical direction of the threaded rod 50. When the threaded barrel 52 descends, it respectively pushes and pulls the sliding seat 61 outward through the four connecting rods 53. The sliding seat 61 moves along the sliding groove 60 of the cross plate 6 in the direction away from the center of the mounting bracket 4, synchronously driving the fixing bracket 62, the second cylinder 7 and the pressing plate 70 to spread outwards to meet the edge compaction requirements of large-sized cardboard boxes.

[0040] Operate the handle 51 in the reverse direction, then the fixing bracket 62, the second cylinder 7 and the pressing plate 70 move inwards to meet the center compaction requirements of small-sized cardboard boxes.

[0041] During the adjustment process, the first rod body and the second rod body of the connecting rod 53 can rotate flexibly through the rotating shaft to avoid jamming caused by angle changes.

[0042] After neatly stacking the folded cardboard boxes on the anti-slip rubber pad on the top of the transfer cart 1, start the first cylinder 3 and the second cylinder 7:

[0043] The telescopic end of the first cylinder 3 extends out, pushing the entire mounting bracket 4 to move downwards. Then turn on the switch of the second cylinder 7 to make the pressing plate 70 descend until the silicone pad at the bottom of the pressing plate 70 approaches the top of the cardboard box, and then turn off the second cylinder 7.

[0044] After the compaction is completed, release the brake of the universal guiding wheels of the transfer cart 1. The operator holds the push rod and pushes the transfer cart 1, and transfers the cardboard box to the designated position in cooperation with the universal wheels.

[0045] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
