Description

Technical Field

[0001] The utility model relates to the technical field of sword-piercing type baling machine equipment, in particular to an anti-collision mechanism of a sword-piercing type baling machine. Background Art

[0002] The sword-piercing baler is an efficient and stable automated packaging equipment, widely used in various industries. It uses mechatronics technology to achieve fast and accurate packaging, improve production efficiency, and ensure product quality. It is an indispensable and important equipment in modern industrial production.

[0003] A Chinese patent discloses an anti-collision type sword-piercing baler, with the publication number CN113291520B. The technical solution disclosed in the patent document is as follows: it includes a placement plate and a body, the body is placed on the placement plate, a frame and a sword are arranged on the body, a placement rack is arranged between the frame and the sword, the placement rack is placed on the placement plate, and the sword is provided with an anti-collision device for preventing collision during the movement of the sword toward the frame and an avoidance mechanism during the connection process; the present invention can form an anti-collision device during the movement of the sword, avoid the collision between the sword and the pallet, and cause damage to the sword-piercing baler, further improving the service life of the sword-piercing baler.

[0004] In order to solve the problem of the lack of anti-collision function on the existing sword, the existing technology uses a collision device to prevent the sword from colliding with the pallet. However, when the sword passes through the pallet and moves toward the frame, the shaft rotates to deflect the baffle downward. During this process, the baffle moves downward a large distance, and the baffle may touch the conveyor at the bottom, thereby causing the end of the sword body to be subjected to a relatively upward thrust, thereby causing damage to the sword body and affecting the accuracy of the sword. For this reason, we propose an anti-collision mechanism for a sword-piercing baler. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a sword-piercing baler anti-collision mechanism to solve the above-mentioned problems existing in the prior art.

When the anti-collision plate is pressed, the upper connecting rod mechanism deflects, and the end of the lower connecting rod mechanism moves along the sword-piercing body, thereby driving the anti-collision plate to move to the bottom of the sword-piercing body.

[0010] Second springs for supporting the upper first connecting rod are arranged on both sides of the sword body.

[0021] The utility model embodiment provides a sword-piercing baler anti-collision mechanism.

[0022] Beneficial effects:

[0023] 1. When the anti-collision plate contacts an obstacle and is compressed, the end of the lower connecting rod mechanism moves along the piercing sword body, driving the anti-collision plate to move closely under the end of the piercing sword body, greatly reducing the downward movement trajectory of the anti-collision plate, avoiding the collision of the anti-collision plate with the conveying device at the bottom when the anti-collision plate is retracted, and greatly improving the practicality of the anti-collision mechanism.

[0024] 2. When the anti-collision plate contacts an obstacle, the connecting rod mechanism deflects, thereby causing the first connecting rod on the upper side to deflect and trigger the switch, causing the equipment to stop running, thereby preventing the sword body from touching the obstacle and causing damage to it.

[0025] 3. If the sword-piercing body does not touch any obstacle during its movement, the push rod will first push the switch to move in the slide slot, and then the anti-collision plate will touch the body and deflect. At this time, the first connecting rod on the upper side will not touch the switch, and the equipment will work normally. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See attached Figure 1-8 A sword-piercing baler anti-collision mechanism comprises a body 1 and a sword-piercing frame 2 arranged on the side thereof for the sword-piercing body 3 to slide. A pair of connecting rod mechanisms 31 are symmetrically arranged on both sides of the front end of the sword-piercing body 3, and an anti-collision plate 32 is rotatably connected through the connecting rod mechanism 31. The anti-collision plate 32 is the same as the rectangular shape formed by the four end points of the side of the sword-piercing frame 2, and can detect obstacles more comprehensively.

[0037] One end of the upper connecting rod mechanism 31 is rotatably connected to the upper side wall of the sword-piercing body 3, and one end of the lower connecting rod mechanism 31 is slidably set on the lower side wall of the sword-piercing body 3. When the anti-collision plate 32 contacts an obstacle and is pressed during the movement of the sword-piercing body 3 toward the body 1, the upper connecting rod mechanism 31 is deflected, and at the same time, the end of the lower connecting rod mechanism 31 moves along the sword-piercing body 3, thereby driving the anti-collision plate 32 to move to the bottom of the sword-piercing body 3, close to the end of the sword-piercing body 3, greatly reducing the downward movement trajectory of the anti-collision plate 32, avoiding the anti-collision plate 32 from colliding with the conveying device at the bottom when it is folded, and greatly improving the practicability of the anti-collision mechanism.

[0038] In this embodiment, the connecting rod mechanism 31 includes a first connecting rod 311 and a second connecting rod 312 which are rotatably connected to each other, and the two are connected by a torsion spring 313. The connecting rod mechanism 31 adopts a two-stage setting, so that the anti-collision plate 32 has greater fault tolerance when it is retracted to the bottom of the sword body 3.

[0039] In this embodiment, the end of the first link 311 of the lower link mechanism 31 away from the second link 312 is slidably arranged on the lower side wall of the sword-piercing body 3, and the end of the second link 312 away from the first link 311 is rotatably connected to the lower side of the anti-collision plate 32. After the anti-collision plate 32 is squeezed, the second link 312 moves along the lower side wall of the sword-piercing body 3. At this time, the first link 311 on the lower side pulls the lower side of the anti-collision plate 32 to move along the sword-piercing body 3, and the second link 312 deflects, thereby driving the bottom of the anti-collision plate 32 to deflect.

[0040] The length of the second connecting rod 312 in the lower side connecting rod mechanism 31 is smaller than the first connecting rod 311. After the second connecting rod 312 is deflected, it exceeds the bottom of the sword-piercing body 3, so that the lower side of the anti-collision plate 32 can move to the bottom of the sword-piercing body 3, and the second connecting rod 312 is short, so that after the anti-collision plate 32 is flipped and retracted, the gap between the top and the bottom of the sword-piercing body 3 is small, which greatly reduces the downward movement trajectory of the anti-collision plate 32 and prevents the anti-collision plate 32 from hitting the conveying mechanism at the bottom when moving.

[0041] In this embodiment, a slide rail 33 is provided on the lower side of the sword-piercing body 3 for the sliding of the lower first connecting rod 311, and a first spring 34 is provided inside the slide rail 33 for supporting the lower first connecting rod 311. When the anti-collision plate 32 is under pressure, the first connecting rod 311 moves along the slide rail 33. When there is no force, the first connecting rod 311 is reset under the action of the first spring 34.

[0042] In this embodiment, the end of the first link 311 of the upper link mechanism 31 away from the second link 312 is rotatably connected to the side wall of the sword body 3, and the end of the second link 312 away from the first link 311 is rotatably connected to the upper side of the anti-collision plate 32. The two-end connecting rod makes the anti-collision plate 32 have more rotation tolerance.

[0043] Furthermore, in order to prevent the first link 311 of the upper link mechanism 31 from deflecting upward, the first link 311 is tilted downward away from the side of the sword-piercing body 3 or a blocking block is provided above the first link 311 on the side wall of the sword-piercing body 3;

[0044] Second springs 35 for supporting the upper first connecting rod 311 are provided on both sides of the sword-piercing body 3. The second spring 35 supports the first connecting rod 311. Through the support of the first spring 34, the upper first connecting rod 311 is kept in a horizontal state, and then the entire connecting rod mechanism 31 and the anti-collision plate 32 are relatively kept in a horizontal state. At this time, the anti-collision plate 32 is arranged as a whole at the front end of the sword-piercing body 3, which can better detect obstacles that hinder the movement of the sword-piercing body 3.

[0045] In this embodiment, a slide groove 36 for the switch 37 to slide is provided on the upper side of the sword-piercing body 3, and a third spring 38 for supporting the switch 37 is provided in the slide groove 36. The switch 37 is electrically connected to the device start-stop controller, and is arranged above the upper first connecting rod 311 away from the end of the second connecting rod 312. When the anti-collision plate 32 touches an obstacle, the upper first connecting rod 311 deflects, which triggers the switch 37, thereby causing the device start-stop controller to work, causing the device to stop working, thereby avoiding the damage of the sword-piercing body 3 caused by the relative collision between the sword-piercing body 3 and the obstacle, thereby greatly improving the safety of the device.

[0046] Push rods 11 cooperating with the switch 37 are provided on both sides of the body 1. After the sword-piercing body 3 passes through the bottom of the items to be packaged and continues to move, the push rod 11 will first push the side of the switch 37 to make it move along the slide groove 36. Then the anti-collision plate 32 will touch the body 1 and deflect. During this process, the first connecting rod 311 on the upper side will not contact the switch 37 when it rotates, and will not cause the equipment to stop working, which facilitates the normal operation of subsequent packaging work.

[0047] In this embodiment, the push rod 11 is in an L-shaped structure as a whole, and the push rods 11 on both sides are arranged outside the body 1 to prevent the push rods 11 from hindering the movement of the anti-collision plate 32.

[0048] In this embodiment, slots 321 for the push rod 11 to pass through are opened on both sides of the anti-collision plate 32. During the movement of the anti-collision plate 32, the push rod 11 can pass through the slots 321, which is convenient for subsequent pushing of the side of the switch 37, so that the switch 37 is away from the first connecting rod 311 on the upper side.

[0049] Working principle: During packaging, the sword-piercing body 3 moves to one side of the machine body 1. When the sword-piercing body 3 encounters an obstacle, the anti-collision plate 32 first contacts the obstacle, causing the connecting rod mechanism 31 to deflect, thereby causing the first connecting rod 311 on the upper side to deflect and triggering the switch 37, causing the equipment to stop running, thereby preventing the sword-piercing body 3 from touching the obstacle and causing damage to it.

[0050] When it touches an obstacle, the anti-collision plate 32 is deflected. At this time, the lower connecting rod mechanism 31 will move along the side wall of the sword-piercing body 3, and the upper connecting rod mechanism 31 will be deflected, so that one side of the anti-collision plate 32 will press against the bottom of the front end of the sword-piercing body 3 and slide downward to the bottom of the sword-piercing body 3 until the anti-collision plate 32 slides to the bottom of the sword-piercing body 3, which greatly reduces the downward movement trajectory of the anti-collision plate 32 and prevents the anti-collision plate 32 from pressing against the conveying mechanism at the bottom when it moves.

[0051] When the sword-piercing body 3 does not touch any obstacle during its movement, the push rod 11 will first push the switch 37 to move in the slide groove 36, and then the anti-collision plate 32 will contact the body 1 and deflect. At this time, the first connecting rod 311 on the upper side will not contact the switch 37, and the device will work normally.
