Description

Technical Field

[0001] This utility model relates to the field of baling machine technology, and specifically to a wire hooking mechanism for baling machines. Background Technology

[0002] In existing industrial packaging equipment, the wire hooking mechanism is the core component for achieving efficient bundling operations. Its motion stability and positioning accuracy directly affect the packaging quality and equipment reliability. In traditional structures, the movement of the push rod is prone to lateral sway during reciprocating motion under dynamic loads. This lateral sway exacerbates friction and wear between the push rod and the guide mechanism, shortening the service life of these components. Frequent maintenance and component replacement increase equipment maintenance costs and production downtime. Furthermore, lateral sway may require operators to spend more time and effort adjusting the equipment's position and status, increasing their workload and stress, and reducing work efficiency. Therefore, there is an urgent need to develop a new wire hooking mechanism with multiple guiding compensations, low friction loss, and easy maintenance. Utility Model Content

[0003] This invention provides a wire hooking mechanism for a baling machine to solve the technical problem of unstable push rod movement in existing wire hooking mechanisms.

[0004] To solve the above problems, the present invention provides a wire-hooking mechanism for a baling machine, which adopts the following technical solution:

[0005] It includes a U-shaped main frame, on which a push rod and a power mechanism for driving the push rod to reciprocate are provided. A movable frame is slidably provided on the U-shaped main frame, and a movable plate is provided at one end of the movable frame. One end of the push rod is fixedly connected to the movable plate.

[0006] The U-shaped main frame is provided with a slide rail that cooperates with the movable frame. The power mechanism drives the movable frame to move back and forth along the slide rail. Both the upper and lower ends of the movable plate are provided with clearance grooves corresponding to the slide rail. Guide rollers are rotatably provided on both sides of the clearance groove.

[0007] Furthermore, the power mechanism is a telescopic rod, and a fixed plate is provided on the U-shaped main frame. One end of the telescopic rod is fixedly connected to the fixed plate, and the other end of the telescopic rod is fixedly connected to the movable frame.

[0008] Furthermore, the movable frame is slidably disposed between two slide rails, and I-shaped wheels that cooperate with the slide rails are located on the side of the movable frame opposite to the slide rails.

[0009] Furthermore, the clearance groove includes a guide groove and an inlet groove that are connected together. The inlet groove is located on the side of the guide groove that is close to the slide rail. The side wall of the inlet groove is inclined. The width of the end of the inlet groove that is close to the slide rail is L1, and the width of the other end of the inlet groove is L2, and L1 > L2.

[0010] Furthermore, the guide groove has a groove on its side wall, and the guide roller is rotatably disposed in the groove.

[0011] Furthermore, a guide plate is provided on the side of the fixed plate away from the movable frame, and the end of the push rod away from the movable plate slides through the fixed plate and the guide plate in sequence.

[0012] The beneficial effects of the wire-hooking mechanism for a baling machine provided by this utility model are:

[0013] This invention utilizes a slide rail to provide both clamping guidance for the movable frame and sliding guidance for the movable plate, achieving a dual-function guiding effect. It is particularly suitable for industrial packaging equipment requiring high frequency, high load, and long service life. When the push rod performs wire hooking or retraction actions, the dual slide rails effectively suppress swaying caused by uneven load or inertia, ensuring the accuracy of the push rod's linear motion.

[0014] In this invention, the inclined sidewall of the guide groove on the moving plate forms a flared structure. When the moving frame moves after resetting, it guides the slide rail smoothly into the guide groove on the moving plate, reducing the need for manual adjustment. The wide inlet facilitates slide rail entry, gradually narrowing to the standard width of the guide groove to ensure precise positioning of the slide rail and prevent misalignment and jamming. Furthermore, during reciprocating motion, if the moving frame experiences slight displacement due to inertia or load changes, the inclined structure provides flexible reset, preventing wear caused by rigid collisions.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0024] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0025] An embodiment of a wire-hooking mechanism for a baling machine provided by this utility model:

[0026] like Figures 1 to 4 As shown, it includes a U-shaped main frame 1, a push rod 2 and a power mechanism 3 for driving the push rod 2 to reciprocate.

[0027] Specifically, the push rod 2 is driven to reciprocate by the power mechanism 2 to achieve the wire hooking operation. The free end of the push rod 2 is provided with a structure for hooking the wire. The wire hooking structure is an existing structure and therefore is not shown in the figure.

[0028] In this embodiment, a movable frame 4 is slidably mounted on the U-shaped main frame 1. One end of the movable frame 4 is provided with a movable plate 41, and one end of the push rod 2 is fixedly connected to the movable plate 41. The U-shaped main frame 1 is provided with a slide rail 11 that cooperates with the movable frame 4, and the power mechanism 3 drives the movable frame 4 to reciprocate along the slide rail 11.

[0029] The power mechanism is a telescopic rod, which in this embodiment may be, but is not limited to, a hydraulic cylinder. A fixed plate 12 is provided on the U-shaped main frame 1. One end of the telescopic rod is fixedly connected to the fixed plate 12, and the other end of the telescopic rod is fixedly connected to the movable frame 4.

[0030] The telescopic rod extends and retracts, causing the movable frame 4 to move back and forth along the slide rail 11. The movement of the movable frame 4 causes the movable plate 41 to move, and the movement of the movable plate 41 synchronously causes the push rod 2 connected to it to move.

[0031] The movable frame 4 is slidably disposed between two slide rails 11, and the movable frame 4 has I-shaped wheels 42 on the side opposite to the slide rails 11 that cooperate with the slide rails 11.

[0032] The movable frame 4 is slidably clamped between two slide rails 11, which increases the stability of its movement. The movable frame 4 is clamped from both sides by the two slide rails 11, forming a stable double-sided guiding constraint, which improves its resistance to eccentric loads by more than 50% compared to a single slide rail design. When the push rod 2 performs hooking or retraction actions, the double slide rails 11 effectively suppress swaying caused by uneven load or inertia, ensuring the linear motion accuracy of the push rod.

[0033] Among them, the fixed plate 12 is provided with a guide plate 13 on the side away from the movable frame 4, and the end of the push rod 2 away from the movable plate 41 slides through the fixed plate 12 and the guide plate 13 in sequence.

[0034] The auxiliary sliding support provided by the fixed plate 12 and the guide plate 13 improves the stability of the push rod 2's movement.

[0035] In this embodiment, both the upper and lower ends of the movable plate 41 are provided with clearance grooves 411 corresponding to the slide rail 11, and guide rollers 412 are rotatably provided on both sides of the clearance grooves 411.

[0036] The clearance groove 411 includes a guide groove 4111 and an inlet groove 4112 connected together. The inlet groove 4112 is located on the side of the guide groove 4111 that is close to the slide rail 11. The side wall of the inlet groove 4112 is inclined. The width of the end of the inlet groove 4112 that is close to the slide rail 11 is L1, and the width of the other end of the inlet groove 4112 is L2, and L1 > L2.

[0037] The guide groove 4111 has a groove 4113 on its side wall, and the guide roller 412 is rotatably disposed in the groove 4113.

[0038] The inclined sidewall of the inlet groove 4112 forms a flared structure, which guides the slide rail 11 smoothly into the guide groove 4111 on the moving plate 41 when the moving frame 4 is moved after being reset, reducing the need for manual adjustment. The wide inlet facilitates the entry of the slide rail 11, and gradually narrows to the standard width of the guide groove 4111 to ensure that the slide rail 11 is finally accurately positioned and avoid misalignment and jamming.

[0039] During reciprocating motion, if the moving frame 4 experiences a slight displacement due to inertia or load changes, the inclined structure can provide flexible reset, avoiding wear caused by rigid collisions.

[0040] In this embodiment, the slide rail 11 provides clamping guidance for the movable frame 4 and sliding guidance for the movable plate 41, achieving a dual-function guiding function. It is particularly suitable for industrial packaging equipment requiring high frequency, high load, and long service life. It offers strong overall stability, mitigates deformation problems caused by impact loads, and improves the service life of the equipment.

Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.
