Description

Technical Field

[0001] This utility model belongs to the technical field of packaging machinery, specifically relating to a push-pull boxing mechanism and device. Background Technology

[0002] In the product packaging production process, boxing is one of the important steps. Existing boxing mechanisms and devices often have problems such as inaccurate pushing, easy product damage, and poor mechanism flexibility when pushing products from the conveyor mechanism into the packaging box. In addition, the current product and packaging box assembly relationship is generally quite compact. Therefore, when the method of pushing the product into the packaging box by extending a pusher plate is adopted, the pusher plate is prone to pulling the product out during the process of exiting the packaging box, which requires rework and results in low boxing efficiency.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a push-pull boxing mechanism and device.

For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] like Figure 1-3 As shown, a push-pull boxing mechanism includes a slide 2, a first slider 12, and a second slider 13. The slide 2 is slidably mounted on a main frame (not shown in the figure) along the longitudinal direction. The main frame can be an independent frame or connected to the boxing conveying mechanism 17. When the main frame is an independent frame, it is fixed to the ground and can be a portal frame, spanning the feeding conveying mechanism 16 and the boxing conveying mechanism 17. Here, the main frame adopts a conventional structure in the art, which only needs to support the push-pull boxing mechanism and does not impose too many restrictions on its specific structure.

[0028] The slide block 2 is provided with a first slide rail 1 that is slidably mounted in the transverse direction. The cross section of the first slide rail 1 can be dovetail-shaped. The first slider 12 is slidably mounted on the first slide rail 1. The first slider 12 is provided with a corresponding dovetail groove. The first slider 12 is provided with a first lever arm 3 that extends forward along the length direction of the first slide rail 1. The first lever arm 3 is fixed by bolts to the side of the first slider 12 away from the first slide rail 1. The front end of the first lever arm 3 is bent downward and connected to the push plate 7.

[0029] The second slider 13 is slidably mounted on the first slide rail 1. The second slider 13 is provided with a corresponding dovetail groove. The second slider 13 is located in front of the first slider 12. The second slider 13 is provided with a second lever arm 4 extending forward along the length direction of the first slide rail 1. The second lever arm 4 is located above the first lever arm 3. After the front end of the second lever arm 4 is bent downward, it is connected to the stop block 5 of the corresponding push plate 7, so that the stop block 5 is located in front of the push plate 7 (or the stop block 5 is located on the side of the push plate 7 away from the product to be boxed), ensuring that the first lever arm 3 and the second lever arm 4 can move independently and that there is no movement interference between them.

[0030] The first slider 12 and the second slider 13 are respectively connected to the first push rod 9 and the second push rod 10. The first push rod 9 and the second push rod 10 can be cylinders or hydraulic cylinders.

[0031] A first longitudinally extending groove is provided at the bend of the first lever arm 3, and a first longitudinally extending connecting plate is provided above the push plate 7. The first connecting plate is slidably assembled in the first groove, and a locking bolt is provided on the first connecting plate to fix the first lever arm 3 at the bend. A corresponding locking bolt is provided in the middle of the first groove, and the locking bolt passes through the locking bolt and is threaded to the first connecting plate to achieve fixation.

[0032] Correspondingly, a second longitudinally extending slot is provided at the bend of the second lever arm 4, and a longitudinally extending second connecting plate is provided above the push plate 7. The second connecting plate is slidably assembled in the second slot, and a locking bolt is provided on the second connecting plate to fix it at the bend of the second lever arm 4. A slotted hole corresponding to the locking bolt is provided in the middle of the second slot. After the locking bolt passes through the slotted hole, it is threaded to the second connecting plate to achieve fixation. Thus, the height of the baffle and the push plate 7 can be finely adjusted according to actual needs to ensure the cooperation between the two.

[0033] In an optional embodiment, the push plate 7 is an inverted T-shaped structure corresponding to the product to be pushed in. The middle of the push plate 7 extends upward and its flat side faces the product to be boxed, thereby pushing the product to be boxed. The middle of the push plate 7 is fixedly connected to the first connecting plate. The front end of the stop block 5 is provided with a pushing part 6 corresponding to both sides of the push plate 7. The pushing part 6 stops the product during the retraction of the push plate 7 to prevent the product from being pulled out.

[0034] A corresponding push plate 7 groove is provided above the stop block 5. The width of the groove is adapted to the push plate 7, thereby reducing the length of the push part 6, making the device structure more compact, and ensuring the effectiveness of the push. The push plate 7 is provided with an inclined part corresponding to the groove. The front end of the inclined part is inclined upward to guide the push plate 7 and avoid hard contact between the push plate 7 and the stop block 5.

[0035] In an optional embodiment, the second lever arm 4 is provided with two guide rods 15 extending along the length of the first slide rail 1. The guide rods 15 guide the stop block 5, and the stop block 5 is slidably mounted on the guide rods 15. A buffer spring 14 is provided on the guide rods 15 between the second lever arm 4 and the stop block 5, so as to avoid hard contact with the stop block 5 caused by large friction between the top plate and the product during the retraction process through buffering and clearance. After the top plate is withdrawn, the product re-enters the packaging box under the pressure of the buffer spring 14 to avoid product damage.

[0036] In one optional embodiment, the main frame is provided with two longitudinally extending second slide rails 11, the cross-section of the second slide rails 11 is dovetail-shaped, the two ends of the slide block 2 are provided with slide grooves corresponding to the second slide rails 11, and the main frame is provided with a longitudinally extending drive rod corresponding to the slide block 2.

[0037] The drive rod is a pneumatic or hydraulic cylinder, which allows for longitudinal adjustment of the slide 2, enabling the top plate to lift the product upwards and ensuring the accuracy of the product being placed into the packaging box.

[0038] A push-pull boxing device includes a feeding conveyor 16 and a boxing conveyor 17 arranged in parallel. The boxing conveyor 17 is provided with a boxing station 18, and any push-pull boxing mechanism is located at the boxing station 18 and crosses the boxing conveyor 17 and the feeding conveyor 16 laterally.

[0039] In this embodiment, both the feeding conveyor 16 and the boxing conveyor 17 include a conveyor belt and a body corresponding to the assembly conveyor belt. Both are conventional technologies and are not subject to excessive restrictions. The boxing station 18 is provided with a guide mechanism corresponding to the push plate 7. The guide mechanism includes two limiting plates 8 corresponding to the boxing station 18. The limiting plate 8 corresponding to the conveying direction of the boxing conveyor 17 extends above the feeding conveyor 16.

[0040] The limiting plate 8, which is away from the conveying direction of the carton conveyor 17, extends to the side edge of the feeding conveyor 16 near the carton conveyor 17.

[0041] The boxing station 18 of the boxing conveying mechanism 17 places the packaging box by suction cup or robotic arm, and the limiting plate 8 above the feeding conveying mechanism 16 blocks the conveyed product to ensure that the product is facing the packaging box. In addition, the distance between the two limiting plates 8 is adapted to the product, thereby forming a push channel for the corresponding product.

[0042] Furthermore, the main frame of the push-pull boxing mechanism can be fixedly connected to the boxing conveyor mechanism 17. The main frame is provided with a second slide rail 11, and the two ends of the slide block 2 are provided with slide grooves corresponding to the second slide rail 11. The main frame is provided with a drive rod that extends longitudinally corresponding to the slide block 2.

[0043] Multiple support members 19 corresponding to the products are provided on the surface of the conveyor belt of the feeding and conveying mechanism 16. Each support member 19 includes two support plates spaced apart. The width of the product to be boxed is greater than that of the support member 19, so that the product to be boxed can be supported. The distance between the two support plates is adapted to the width of the push plate 7. After the product to be boxed is stopped and positioned by the limiting plate 8, the drive rod drives the push plate 7 to descend and extend from front to back between the two support plates. Then, the drive rod drives the product to be boxed upward to lift it up so that the product to be boxed is facing the opening of the packaging box.

[0044] 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, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
