Description

Technical Field

[0001] This utility model relates to the field of rope threading machines, specifically to an opening mechanism for a carton rope threading machine. Background Technology

[0002] Existing rope-threading machines are generally used for threading ropes onto paper bags. For example, a rope-threading machine for tote bags disclosed in CN222039835U on 2024-11-22 uses a conveying mechanism to pick up the tote bags from the feeding mechanism and transport them directly into the punching mechanism and the rope-threading mechanism. Because paper bags have small openings and paper boxes have large openings, the paper boxes need to be opened before punching and threading ropes. Therefore, this type of rope-threading machine would have limitations if applied to paper boxes. Thus, there is an urgent need for a rope-threading machine specifically for paper boxes.

[0030] Figure 6 This is a schematic diagram of the structure of Example 4. Detailed Implementation

[0031] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0032] As shown in the figure, an opening mechanism for a carton threading machine includes a suction assembly 1. The suction assembly 1 includes a suction cup seat 11 and a first power component that drives the suction cup seat 11 to move back and forth. It also includes a material blocking component located on at least one side of the suction cup seat 11 and a second power component that drives the material blocking component to move back and forth. The movement trajectories of the material blocking component and the suction cup seat 11 are parallel to each other. This technical solution uses the first power component to drive the suction cup seat to move back and forth. The suction cup seat can attract the folded carton and retract it backward. During the retraction process, the second power component drives the material blocking component to move forward. After contacting both ends of the carton, it continues to move forward, realizing the opening action of the carton. It has the advantages of good working stability and good practicality.

[0033] The cardboard box is originally folded into a flat shape. The material blocking component can be set on one side of the suction cup base or on both sides of the suction cup base. Both can realize the opening action of the cardboard box. Setting it on one side of the suction cup base can fully realize the opening action of the cardboard box. The reason for setting it on both sides of the suction cup base is that the orientation of the cardboard box is not uniform. Sometimes the short side is on the right and sometimes the short side is on the left. Therefore, setting the material blocking component on both sides can ensure the stability of opening the cardboard box.

[0034] The material-blocking component in this technical solution has three embodiments;

[0035] Example 1: As Figure 1 As shown, the side of the baffle block 211 near the suction cup seat 11 is a sloping surface, and the sloping surface of the baffle block can guide the two sides of the carton.

[0036] Example 2: Figure 5 As shown, the material blocking component includes a first material blocking seat 212, a first baffle 213 hinged to the first material blocking seat 212, and a fourth driving member 214 mounted on the first material blocking seat 212 and driving the first baffle 213 to swing. The fourth driving member is a cylinder, hydraulic cylinder, or linear motor, and the output end of the fourth driving member is hinged to the first baffle, which can drive the first baffle to swing on the first material blocking seat. The first baffle and the first material blocking seat are connected by a pin, and the hole on the first baffle is appropriately enlarged to prevent the first baffle from getting stuck when swinging.

[0037] Example 3: Figure 4 As shown, the material blocking component includes a second material blocking seat 215, a second baffle 216 slidably mounted on the second material blocking seat 215, and a fifth driving member 217 mounted on the second material blocking seat 215 and driving the second baffle 216 to slide. The fifth driving member is a cylinder, a hydraulic cylinder, or a linear motor, which controls the second baffle to move toward the suction cup seat to complete the carton opening operation.

[0038] Example 4: The material blocking component includes a third material blocking seat 218 and an adsorption nozzle 219 installed on the inner side wall of the third material blocking seat. The paper box is first touched by the third material blocking seat, and then the side of the paper box is tilted and comes into contact with the adsorption nozzle and is adsorbed until the paper box opening work is completed.

[0039] It also includes a bracket 3 for mounting the first power component and the second power component.

[0040] The first power component includes:

[0041] The first driving component 12 is fixedly mounted on the bracket 3 and its output end is provided with a first gear 13;

[0042] The first rack 14 is slidably mounted on the bracket 3 and meshes with the first gear 13;

[0043] The end of the first rack 14 is fixedly connected to the suction cup seat 11. The first driving component is a servo motor, which drives the first rack to move back and forth through the forward and reverse rotation of the first gear.

[0044] In another embodiment of the first power component, a cylinder, hydraulic cylinder, or linear motor is used, with its output end fixedly connected to the suction cup base.

[0045] The suction cup base 11 has several first guide shafts 15 at the four corners that slide and cooperate with the bracket 3, which ensures the stability of the suction cup base's back and forth movement. The front surface of the suction cup base 11 is provided with several suction nozzles 16, which are connected to a negative pressure device through a hose to firmly adhere to the side wall of the carton.

[0046] The second power component includes:

[0047] The connecting frame 22 has connecting rods 23 at both ends that are fixedly connected to the material stop component;

[0048] The second driving component 24 is fixedly mounted on the bracket 3 and its output end is provided with a second gear 25;

[0049] The movable seat 26 is slidably mounted on the bracket 3 and connected to the connecting frame 22;

[0050] The second rack 27 is fixedly mounted on the movable seat 26 and meshes with the second gear 25. The second drive component is a servo motor, which drives the second rack and the movable seat to move back and forth through the forward and reverse rotation of the second gear. The movable seat drives the connecting rods and stop blocks on both sides to move back and forth synchronously through the connecting frame.

[0051] It also includes an adjusting component for adjusting the lateral position of the material stop component, the adjusting component comprising:

[0052] Two adjusting brackets 28 are symmetrically arranged on both sides of the suction assembly 1 and slide in cooperation with the connecting rod 23;

[0053] The screw 29 has a positive thread 291 and a negative thread 292 at both ends that are threaded to the adjusting bracket 28;

[0054] The third driving component 20 has its output end linked to the end of the screw 29. The third driving component adopts a servo motor and pulley structure, which drives the screw to rotate. The positive thread and negative thread on the screw can realize the synchronous opposite movement of the two adjustment frames.

[0055] The bracket 3 is provided with several second guide shafts 31 that slide and cooperate with the adjustment frame 28, ensuring the smooth operation of the adjustment frame.

[0056] Another embodiment of the second power component is to use a cylinder, hydraulic cylinder, or linear motor, with its output end fixedly connected to the stop block, and the synchronization of the two is controlled by a PLC control system.
