DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] like Figure 1-3 As shown, the present application proposes a packaging box partition distance changing mechanism, which is used for longitudinal distance changing between a plurality of partitions 40, and includes a linear driving member 10, a cardboard conveying portion 20 and a paper receiving portion 30, wherein the cardboard conveying portion 20 includes a bottom mounting plate 210, a guide rod mounting plate 220, a guide rod 230, and a conveying portion connecting block 240; a plurality of cardboard conveying slideways 211 are longitudinally spaced on the bottom mounting plate 210, and the longitudinal distance between one end of the plurality of cardboard conveying slideways 211 is greater than the longitudinal distance between the other ends of the plurality of cardboard conveying slideways 211, and the bottom mounting plate 210 is longitudinally spaced. Two guide rod mounting plates 220 are arranged on the plate 210 at intervals in the longitudinal direction, at least one guide rod 230 is connected between the two guide rod mounting plates 220, a plurality of conveying portion connecting blocks 240 are sleeved on the guide rod 230, and the plurality of conveying portion connecting blocks 240 are slidably connected to the plurality of paperboard conveying slideways 211 in a one-to-one correspondence, and a paper receiving portion 30 is respectively arranged on the top of the plurality of conveying portion connecting blocks 240; the output end of the linear drive member 10 is transmission-connected to the guide rod mounting plate 220, so that the guide rod mounting plate 220 performs reciprocating motion in the lateral direction.

[0024] Specifically, the linear drive component 10 of the present application can use a linear drive device such as a rodless cylinder, an electric slide rail, etc. The linear drive component 10 is arranged on one side of the bottom mounting plate 210, which can effectively reduce the thickness of the entire mechanism and make the entire variable pitch mechanism present a planar layout effect. The linear drive component 10 only needs a narrower spacing, which effectively shortens the longitudinal length occupied by the entire variable pitch mechanism.

[0025] The present application does not limit the shape of the cardboard conveying slide 211, but only needs to limit the lateral spacing between the two ends of each cardboard conveying slide 211, so that after the paper receiving part 30 slides from one end to the other end along the cardboard conveying slide 211, the distance between the paper receiving parts 30 on adjacent cardboard conveying slides 211 changes.

[0026] Preferably, the middle section of the paperboard conveying slide 211 is straight and arranged at a transverse angle, and the two ends of the paperboard conveying slide 211 are arranged in the transverse direction, so that when the paper receiving parts 30 are at the two ends of the paperboard conveying slide 211, the paper receiving parts 30 remain parallel to each other;

[0027] Alternatively, the middle section of the paperboard conveying slide 211 is arc-shaped, and both ends of the paperboard conveying slide 211 are arranged in the transverse direction;

[0028] Furthermore, the middle section of the paperboard conveying slide 211 is wave-shaped, and both ends of the paperboard conveying slide 211 are arranged in the transverse direction.

[0029] When in use, the output end of the linear drive member 10 drives the guide rod 230 and the plurality of paper receiving parts 30 penetrated by the guide rod 230 to slide horizontally as a whole through the guide rod mounting plate 220. Since there is a one-to-one corresponding sliding connection relationship between the plurality of paper receiving parts 30 and the plurality of cardboard conveying slides 211, the movement of each paper receiving part 30 is decomposed into sliding along the cardboard conveying slide 211 + sliding along the guide rod 230, until the plurality of paper receiving parts 30 slide from one end of the plurality of cardboard conveying slides 211 to the other end thereof, the linear drive member 10 stops moving, and the spacing distance between the plurality of paper receiving parts 30 is reduced, so as to prepare for the transfer of the partition on the paper receiving part 30; after the partition on the paper receiving part 30 is transferred, the linear drive member 10 moves in the opposite direction, until the plurality of paper receiving parts 30 slide from the other end of the plurality of cardboard conveying slides 211 to one end thereof, and the linear drive member 10 stops moving.

[0030] The linear drive member 10 directly drives the guide rod mounting plate 220 to move to realize the movement of the paper receiving part 30, so that the linear drive member 10, the guide rod mounting plate 220, and the paper receiving part 30 can be arranged in the same direction, and the parallel arrangement has a small interval and a compact space, so that several partitions can be synchronously changed in distance.

[0031] As one of the embodiments of the present application, in order to increase the sliding stability of the conveying section connecting block 240 and avoid the shaking of the paper receiving section 30, a plurality of guide rods 230 are arranged at laterally intervals between the two guide rod mounting plates 220, and linear bearings 241 are respectively arranged at both ends of the conveying section connecting block 240, and the two linear bearings 241 are respectively mounted on the two guide rods 230.

[0032] Specifically, the utility model provides four cardboard conveying slideways 211 on the bottom mounting plate 210, and four guide rods 230 and four conveying part connecting blocks 240 are arranged correspondingly; among the four conveying part connecting blocks 240 arranged at intervals in the longitudinal direction, the linear bearing 241 at one lateral end of the first conveying part connecting block 240, the conveying part connecting block 240, and the linear bearing 241 at the other lateral end are sequentially sleeved on the first, second, and third guide rods 230 of the lateral interval, and the third conveying part connecting block 240 is arranged in the same manner as the first conveying part connecting block 240; the linear bearing 241 at one lateral end of the second conveying part connecting block 240, the conveying part connecting block 240, and the linear bearing 241 at the other lateral end are sequentially sleeved on the first, second, and third guide rods 230 of the lateral interval. The conveying section connecting block 240 and the linear bearing 241 at the other lateral end are sequentially mounted on the second, third and fourth guide rods 230 spaced laterally, and the fourth conveying section connecting block 240 is arranged in the same manner as the second conveying section connecting block 240; this staggered arrangement avoids movement interference of local components; for example, the width of the conveying section connecting block 240 is a, and the shortest center distance between two adjacent conveying slideways 211 is b, a>b, at this time, interference will occur when several conveying section connecting blocks 240 are arranged in parallel, and when the staggered arrangement is used, there is a margin on both sides of the middle section of the two adjacent conveying section connecting blocks 240, thereby avoiding interference and meeting the sliding requirements.

[0033] As one of the embodiments of the present application, in order to further improve the smoothness of the sliding of the conveying portion connecting block 240 on the cardboard conveying slide 211 and reduce the friction during its sliding, a cam bearing follower 250 is provided at the bottom of the conveying portion connecting block 240, and the cam bearing follower 250 is rollingly arranged on the corresponding cardboard conveying slide 211.

[0034] In the present utility model, as shown in the attached Figure 3 As shown, the paper receiving portion 30 includes a clip bottom plate 310, a clip side plate 320 and a clip spacer 330. Two of the clip side plates 320 are spaced apart at the top of the clip bottom plate 310 so that a partition placement space is formed between the two clip side plates 320. The clip side plates 320 extend in the transverse direction, and clip spacers 330 are respectively provided between the two clip side plates 320 and at the transverse ends of the partition placement space.

[0035] Specifically, the two clip side plates 320 are connected by bolts, and the bolts penetrate the clip spacer 330, so that the clip spacer is clamped and fixed by the two clip side plates 320, and prevented from falling off; the partition placement space can accommodate the partition.

[0036] In addition, the present application further includes an operating platform 50 , and the linear drive member 10 and the paperboard conveying unit 20 are respectively arranged on the operating platform 50 .

[0037] In the present application, the transverse direction mentioned in the present application refers to the width direction of the platform 50 , and the longitudinal direction mentioned in the present application refers to the length direction of the platform 50 .

[0038] The simultaneous operation of multiple cardboard conveying units 20 is achieved through the operating platform 50, which is more suitable for the large-scale assembly line type partition pitch change requirements; specifically, the linear drive member 10 and the corresponding cardboard conveying unit 20 form a pitch change component, and multiple pitch change components are arranged longitudinally on an operating platform to provide conditions for large-scale assembly line operations.

[0039] For each variable pitch assembly, there is only a single-sided connection between the linear drive component 10 and the guide rod mounting plate 220. There is still a risk of jamming during the reciprocating motion of the guide rod mounting plate 220. A linear slide rail 520 is arranged on the operating platform 50. The linear slide rail 520 is located on the side of the bottom mounting plate 210 away from the linear drive component 10. The linear slide rail 520 extends horizontally. A slider 510 is slidably arranged on the linear slide rail 520. The slider 510 is connected to the bottom mounting plate 210.

[0040] The specific connection relationship between the slider 510 and the bottom mounting plate 210 is as follows: the slider 510 is located at one side of the bottom mounting plate 210 , and the top of the slider 510 is connected to the top of the bottom mounting plate 210 via a slider connecting plate 530 .

[0041] Specifically, the shape of the slider connecting plate 530 is determined according to the shape and distance between the slider 510 and the bottom mounting plate 210 , and its outer shape structure does not need to be specified.

[0042] In order to provide a mounting side for the linear drive 10, a drive bracket 540 is provided on the operating platform 50, and the linear drive 10 is fixed on the side of the drive bracket 540; the shape of the drive bracket 540 is L-shaped.

[0043] The specific connection relationship between the linear drive member 10 and the guide rod mounting plate 220 of the present application is: the output end of the linear drive member 10 is connected to the guide rod mounting plate 220 via the drive member connecting plate 110 .

[0044] Specifically, the output end of the linear drive member 10 is longitudinally spaced apart from the bottom mounting plate 210 , and the drive member connecting plate 110 is bolted to the top surface of the output end of the linear drive member 10 and the top surface of the guide rod mounting plate 220 , respectively.

[0045] In a specific embodiment, as shown in the attached Figure 1 As shown, a bottom mounting plate 210 is connected to both longitudinal sides of the output end of each linear drive member 10, and a linear guide rail 520 is connected to the other side of each bottom mounting plate 210; in this way, the paper receiving parts 30 on the two cardboard conveying parts 20 of one-to-two can change the distance at the same time, which saves the number of linear drive members 10 used and saves costs.

[0046] In the present application, in order to limit and buffer the movement of the paper-jointing portion 30 from one end of the cardboard conveying slide 211 to the other end of the cardboard conveying slide 211, a first hydraulic buffer 560 is provided on the driving member connecting plate 110 or the guide rod mounting plate 220, and a first travel limit block 550 is provided on the side of the driving member bracket 540 corresponding to the first hydraulic buffer 560.

[0047] Specifically, the first hydraulic buffer 560 is fixed to the driving member connecting plate 110 through an L-shaped bracket. When the paper receiving portion 30 slides close to the other end of the paperboard conveying slide 211 , the first hydraulic buffer 560 contacts the first travel limit block 550 .

[0048] In the present application, in order to limit and buffer the movement of the paper docking part 30 from the other end of the cardboard conveying slide 211 to one end of the cardboard conveying slide 211, a second hydraulic buffer 570 is arranged on the driving member connecting plate 110 or the guide rod mounting plate 220, and a second travel limit block 580 is arranged on the operating platform 50 corresponding to the second hydraulic buffer 570.

[0049] Specifically, the second hydraulic buffer 570 is fixed to the driving member connecting plate 110 through an L-row bracket. When the paper receiving portion 30 slides close to one end of the paperboard conveying slide 211 , the second hydraulic buffer 570 contacts the second travel limit block 580 .

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
