Description

Technical Field

[0001] The invention relates to the technical field of packaging machinery, in particular to a box-stuffing mechanism used in a box-stuffing machine. Background Art

[0002] Carton packaging plays a very important role in the storage, transportation, and sales of goods. When the materials are processed on the production line, they need to be packaged with cartons at the end. For some square strip materials (such as slide rails), the packaging method is usually box-type packaging, that is, the carton is placed on the end of the material to form a package, and the gap between the carton and the material is generally small, so that the carton will be close to the surface of the material and not easy to slide off. Therefore, the size of the carton port is similar to that of the material end, which makes it difficult for existing cartoning machines to quickly and accurately put the carton on the end of the material. Summary of the invention

[0003] In order to overcome the defects in the prior art, the task of the present invention is to provide a box-sleeving mechanism for a box-sleeving machine, through which a paper box can be quickly and accurately sleeved on a material.

[0004] The task of the present invention is achieved through the following technical solutions:

[0005] A box-sleeving mechanism for a box-sleeving machine comprises a carton pushing mechanism, a box-sleeving guiding mechanism and a material positioning mechanism. The carton pushing mechanism comprises a push plate and a first transverse movement mechanism for driving the push plate to move transversely. The box-sleeving guiding mechanism comprises a U-shaped guide cover with an opening facing downward, a first lifting mechanism for driving the guide cover to move up and down, and a second transverse movement mechanism for driving the first lifting mechanism to move transversely. The guide cover comprises a cover body and an elastic cover protruding outward from one end of the cover body. The elastic cover is composed of a plurality of spring pieces inclined inwardly in a natural state. The base of each spring piece is respectively connected to the inner side wall of the cover body and is flush therewith, and the port of the elastic cover faces the carton pushing mechanism.

[0006] As a preferred technical solution, the material positioning mechanism includes a positioning plate and a second lifting mechanism that drives the positioning plate to move up and down.

[0007] As a preferred technical solution, the box guide mechanism further includes a guide channel fixedly arranged between the paper box ejection mechanism and the guide cover.

[0008] During operation, the positioning pressure plate of the material positioning mechanism moves downward to press the material to position the material, and then the guide cover of the box sleeve guide mechanism moves downward to cover the material, wherein the cover body covers the end of the material and the elastic cover extends outward, and then the carton pushing mechanism pushes the carton located at the end of the carton feeding mechanism toward the end of the material until it is sleeved on the outside of the elastic cover. Since the spring pieces of the elastic cover are inclined inward, the carton port can be easily sleeved on the outside of the elastic cover, and then the guide cover and the material pushing mechanism move laterally synchronously. Since the spring pieces of the elastic cover are elastic, the elastic cover can expand outward and sleeve on the outside of the material end under the squeezing of the material end when it moves to the end of the material, and at the same time, the carton port is still sleeved on the outside of the elastic cover, and then the guide cover continues to move laterally and is pulled out from between the carton port and the material end. At this time, the carton is sleeved on the end of the material. After the carton is completely sleeved on the end of the material, the material positioning mechanism, the guide cover, and the carton pushing mechanism are all reset, waiting for the next box sleeve.

[0009] Compared with the prior art, the box-sleeving machine of the present invention has the following advantages: by providing a box-sleeving guide mechanism, the box can be quickly and accurately put on the material even if the box port and the material end are of similar size; by providing a guide channel, when the box-pushing mechanism pushes the box to move, the box can be guided so that it can be accurately put on the outside of the elastic cover.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below by taking a box-setting machine using the box-setting mechanism of the present invention as an embodiment and combining with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0018] It should be noted that the terms "front", "rear", "inside", "outside" and similar expressions used in this article are only for illustrative purposes and do not represent the only implementation method.

[0019] like Figure 1 , 2 As shown, a box-stuffing machine comprises a machine base 1, a material conveying mechanism 2 arranged on the machine base 1, a carton feeding mechanism 3 symmetrically arranged on both sides of the material conveying mechanism 2, and a box-stuffing mechanism 4 arranged at the end of the carton feeding mechanism 3. The box-stuffing mechanism 4 is the box-stuffing machine head of the present invention.

[0020] like Figure 3 , 4 As shown, the box-setting mechanism 4 includes a carton pushing mechanism 41, a box-setting guiding mechanism and a material positioning mechanism. The carton pushing mechanism 41 includes a push plate 411 and a first transverse movement mechanism 412 for driving the push plate 411 to move laterally. The box-setting guiding mechanism includes a U-shaped guide cover 421 with an opening facing downward, a first lifting mechanism 422 for driving the guide cover 421 to move up and down, and a second transverse movement mechanism 423 for driving the first lifting mechanism 422 to move laterally. The guide cover 421 includes a cover body 4211, and an elastic cover 4212 protruding outward from one end of the cover body 4211. The elastic cover 4212 is composed of three spring pieces 42121 that are inclined inwardly in a natural state. The base of each spring piece 42121 is respectively connected to the upper, left and right inner walls of the cover body 4211 and is flush therewith. The port of the elastic cover 4212 is directly opposite to the carton pushing mechanism 41.

[0021] During operation, the material conveying mechanism 2 conveys the material 5 to the box-setting station, and then the positioning pressure plate of the material positioning mechanism moves downward to press the material to position the material, and then the guide cover 421 of the box-setting guide mechanism moves downward to cover the material, wherein the cover body 4211 covers the end of the material, and the elastic cover 4212 extends outward, and then the carton pushing mechanism 41 pushes the carton 6 located at the end of the carton feeding mechanism 3 toward the end of the material until it is sleeved on the outside of the elastic cover 4212. Since the spring pieces 42121 of the elastic cover 4212 are inclined inwardly, the carton port can be easily sleeved on the outside of the elastic cover 4212, and then the guide cover 421 and the material pushing mechanism are simultaneously The elastic cover 4212 moves laterally. Since the spring pieces 42121 of the elastic cover 4212 are elastic, the elastic cover 4212 can expand outwards and be sleeved on the outside of the material end under the pressure of the material end when it moves to the end of the material. At the same time, the paper box port is still sleeved on the outside of the elastic cover 4212. The spring pieces 42121 are elastic thin sheets, which are located between the inner wall of the paper box and the outside of the material and do not occupy much gap. Then the guide cover 421 continues to move laterally and is pulled out from between the paper box port and the end of the material. At this time, the paper box is sleeved on the end of the material. After the paper box is completely sleeved on the end of the material, the material positioning mechanism, the guide cover 421, and the paper box ejection mechanism 41 are all reset, waiting for the next sleeve.

[0022] As a preferred embodiment, Figure 3 As shown, the material positioning mechanism includes a positioning platen 431 and a second lifting mechanism 432 for driving the positioning platen 431 to move up and down.

[0023] As a preferred embodiment, the box sleeve guiding mechanism also includes a trumpet-shaped guide channel (not shown in the drawings) fixedly arranged between the paper box ejecting mechanism 41 and the guide cover 421. By setting the guide channel, when the paper box ejecting mechanism 41 pushes the paper box to move, the paper box can be guided so that it can be accurately sleeved on the outside of the elastic cover 4212.

[0024] As a preferred embodiment, Figure 1 , 2 As shown, the material conveying mechanism 2 includes a first material conveying mechanism 21, a stacking and sorting mechanism 22, and a second material conveying mechanism 23, which are arranged in sequence from front to back. The stacking and sorting mechanism 22 includes a lifting frame 221, a limiting side plate 222, a support plate, and a third lifting mechanism (not shown in the drawings) for driving the lifting frame 221 to move up and down. The upper surface of the lifting frame 221 is an inclined surface inclined obliquely downward. By setting the stacking and sorting mechanism 22, when the first material conveying mechanism 21 conveys the material to the top of the lifting frame 221, the lifting frame 221 moves upward, the material can be lifted and turned forward, and supported by the support plate, so that multiple materials can be stacked and neatly stacked under the limiting action of the limiting side plate 222.

[0025] As a preferred embodiment, a fourth lifting mechanism (not shown in the drawings) for driving the lifting movement of the pallet is provided below the pallet, so as to adjust the height of the material.

[0026] As a preferred embodiment, Figure 1 , 2 As shown, the first material conveying mechanism 21 includes a material conveying belt 211 for conveying materials from front to back, and a limiting strip 212 arranged above the material conveying belt 211; by setting the limiting strip 212, the material on the first material conveying mechanism 21 can be limited.

[0027] As a preferred embodiment, Figure 1-3 As shown, the second material conveying mechanism 23 includes a conveying channel, a U-shaped bracket 231 with an upward opening arranged in the conveying channel, a fifth lifting mechanism 232 for driving the bracket 231 to move up and down, and a longitudinal movement mechanism 233 for driving the fifth lifting mechanism 232 to move forward and backward; by setting the U-shaped bracket 231, the U-shaped groove of the bracket 231 can be used to drag the material to the boxing station and limit the material in the front and rear directions. At the same time, the outer edge of the bracket 231 can also be used to drag the material that has been boxed before forward, and the conveying channel is used to support the material.

[0028] As a preferred embodiment, Figure 5 As shown, the carton feeding mechanism 3 includes a carton bin 31, a carton grabbing mechanism 32, a carton conveyor belt 33, and a paper folding and sealing mechanism 34 arranged outside the carton conveyor belt 33. The carton conveyor belt 33 is arranged below the carton bin 31. The carton conveyor belt 33 is composed of chains arranged in parallel. The teeth arranged at intervals on the two chains cooperate to form a carton bracket 35. The carton grabbing mechanism 32 is located between the two chains and directly below the carton bin 31. The carton grabbing mechanism 32 includes a suction cup 32. 1 and a sixth lifting mechanism 322 for driving the suction cup 321 to move up and down; the carton in the carton bin 31 is generally a pre-pressed cardboard 61. When the cardboard is grabbed and moved to the carton bracket 35 formed by the latch teeth by the suction cup 321, the cardboard is formed into a carton 6 under the action of the carton bracket 35, and then transported to the end by the carton conveyor belt 33. During the transportation process, the cover plate of the outer port of the carton is sealed under the action of the paper folding sealing mechanism 34, and there is no cover plate at the inner port of the carton, which is used to cover the end of the material.
