[0002] Cardboard film cutting machine is a kind of equipment specially used for cardboard processing. It is mainly used to cut film windows of various shapes on cardboard for subsequent window pasting, laminating and other processes. This equipment is widely used in the packaging industry, especially in the production of paper boxes, gift boxes, display boxes and other products with transparent windows. In addition to the basic film cutting function, some high-end cardboard film cutting machines also have additional functions such as punching, creasing, folding, etc., which can complete multiple processing operations at one time.

[0003] When using a cardboard die cutter, the cardboard needs to be placed flatly into one of the feed ports of the die cutter. In the related art, a flat belt or a V-belt is used, driven by a motor, to smoothly convey the paper from one position to the feed port of the die cutter. This is the most common paper conveying method, but this method requires workers to place the paper to be processed on the conveyor belt in sequence and accurately, and when the placement position deviates, the processing position of the cardboard will also deviate, thereby affecting the processing effect of the cardboard.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

The two limit blocks 2 are arranged opposite to each other and the length directions of the two limit blocks 2 are parallel to each other. The side where the two limit blocks 2 are close to each other is set as an inclined surface and the limit blocks 2 gradually shrink from top to bottom.

[0028] A blocking plate 3 for blocking cardboard is provided between the conveying end point of the conveyor belt 1 and the limit block 2. The blocking plate 3 is arranged in a rectangular shape and the end face of the blocking plate 3 is perpendicular to the conveying direction of the conveyor belt 1. A control mechanism 4 for controlling the rise and fall of the limit block 2 and the blocking plate 3 is provided on one side of the conveyor belt 1.

[0029] The control mechanism 4 includes a support plate 41, which is located on one side of the conveyor belt 1 and fixed to the ground. A balance bar 42 is provided on the side of the support plate 41 close to the conveyor belt 1. The length direction of the balance bar 42 is parallel to the conveying direction of the conveyor belt 1, and the midpoint of the length direction of the balance bar 42 is rotatably connected to the support plate 41. A first limiting rod 43 and a second limiting rod 44 are provided on both sides below the midpoint of the length direction of the balance bar 42, respectively. The first limiting rod 43 and the second limiting rod 44 are both fixedly connected to the support plate 41, and the length directions of the first limiting rod 43 and the second limiting rod 44 are perpendicular to the end face of the balance bar 42. A first connecting rod 45 is passed through and slidably connected to the first limiting rod 43. Two sliding holes 421 are provided on the balance bar 42, and the sliding holes 421 are located on both sides of the rotation connection between the balance bar 42 and the support plate 41, and the sliding holes 421 are arranged along the length direction of the balance bar 42. One end of the first connecting rod 45 is passed through and slidably connected to the sliding hole 421 of the balance bar 42 near the transmission end of the conveyor belt 1, and the first connecting rod 47 is slidably connected to the balance bar 42 through the sliding hole 421. The other end of the first connecting rod 45 is fixedly connected to the blocking plate 3.

[0030] A second connecting rod 46 is inserted through and slidably connected to the second limiting rod 44. The second connecting rod 46 is inserted through and slidably connected to the second limiting rod 44. One end of the second connecting rod 46 is inserted through and slidably connected to the sliding hole 421 on the side of the balance rod 42 away from the conveying end point of the conveyor belt 1. The other end of the second connecting rod 46 is fixedly connected to a connecting rod 47. The length direction of the connecting rod 47 is parallel to the belt surface of the conveyor belt 1. The ends of the connecting rod 47 are fixedly connected to the two limiting blocks 2 respectively. The first connecting rod 45 and the second connecting rod 46 are both arranged at right angles.

[0031] Reference Figure 1 , Figure 2 and Figure 3A driving assembly 48 for driving the balance bar 42 to swing back and forth is provided on the support plate 41. The driving assembly 48 includes a cylinder 481 arranged on the support plate 41. The end of the telescopic end of the cylinder 481 is hinged with a transmission rod 482. The end of the transmission rod 482 away from the cylinder 481 is fixedly connected to the upper end at the midpoint of the length direction of the balance bar 42. The end of the cylinder 481 away from its own telescopic end is hinged on the support plate 41.

[0032] Thus, the cylinder 481 can be controlled to repeatedly extend and retract, so that the cylinder 481 drives the balance bar 42 to swing up and down on the support plate 41 through the transmission rod 482, so that the first connecting rod 45 and the second connecting rod 46 slide in the slide hole 421, and under the action of the first limiting rod 43 and the second limiting rod 44, the limiting block 2 and the blocking plate 3 can only slide back and forth in the direction perpendicular to the belt surface of the conveyor belt 1, and the movement directions of the limiting block 2 and the blocking plate 3 are opposite at the same time. Thus, when the paper falls on the conveyor belt 1, the two limiting blocks 2 adjust the position of the paperboard when they rise, so that the two sides of the single or superimposed paperboard can be kept flush, and then when the blocking plate 3 falls on the conveyor belt 1, the conveyor belt 1 continues to convey, and the end of the paperboard abuts on the blocking plate 3 and the blocking plate 3 can adjust the position of the end of the paperboard, and then the position of the two sides of the paperboard and the end position can be adjusted in turn. So that the paper is in the correct position on the conveyor belt 1.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The bottom surface of the storage bin body 5 includes a fixed portion 52 and a movable portion 51. The movable portion 51 is located on the side of the storage bin body 5 close to the conveyor belt 1. One end of the movable portion 51 is rotatably connected to the fixed portion 52, and the movable portion 51 can be turned downward on the fixed portion 52. A torsion spring 53 is provided at the rotation connection between the movable portion 51 and the fixed portion 52. Under the action of the torsion spring 53, the movable portion 51 and the fixed portion 52 are placed in the same plane.

[0034] Reference Figure 1 , Figure 2 and Figure 3 , the storage bin body 5 is provided with an adjustment mechanism 6 for controlling the cardboard from the storage bin body 5 to enter the conveyor belt 1. The adjustment mechanism 6 includes an abutment rod 61, the abutment rod 61 has two right-angle bending points, one end of the abutment rod 61 is passed through and slidably connected to the slide hole 421 on the side of the balance bar 42 close to the conveying starting point of the conveyor belt 1, and the other end of the abutment rod 61 abuts against the upper end surface of the movable part 51, and a third limiting rod 62 is fixedly connected to the support plate 41, and the length direction of the third limiting rod 62 is perpendicular to the support plate 41, and the middle section of the abutment rod 61 is passed through and slidably connected to the third limiting rod 62.

[0035] Under the restriction of the third limit rod 62, the abutment rod 61 can only move up and down along the upper end surface perpendicular to the conveyor belt 1. When the balance rod 42 swings, the abutment rod 61 will move reciprocatingly up and down under the action of the sliding hole 421, so that the lower end of the abutment rod 61 reciprocates and abuts against the movable part 51, and the movable part 51 overcomes the force of the torsion spring 53 and bends downward, so that the cardboard on the movable part 51 is separated from the storage bin 5 and falls onto the conveyor belt 1.

[0036] The adjustment mechanism 6 also includes a position limiting assembly 63 for limiting the position of the cardboard in the storage bin body 5. The position limiting assembly 63 includes a squeeze plate 631 disposed at the upper part of the storage bin body 5, the end surface of the squeeze plate 631 is parallel to the upper and lower end surfaces of the storage bin body 5, and a plurality of limit springs 632 are fixedly connected between the squeeze plate 631 and the inner wall of the storage bin body 5. Under the action of the limit springs 632, the squeeze plate 631 presses the plurality of cardboards tightly in the storage bin body 5.

[0037] A connecting rope 633 is fixedly connected to the telescopic end of the cylinder 481, and a winding post 12 is fixedly connected to the upper end of the support plate 41. The axial direction of the winding post 12 is perpendicular to the end face of the support plate 41, and the end of the connecting rope 633 away from the cylinder 481 passes around the upper end of the winding post 12, passes through the upper end face of the storage bin body 5, and is fixedly connected to the extrusion plate 631.

[0038] Then, when the cylinder 481 is extended, the connecting rope 633 will drive the squeezing plate 631 to rise and cancel the contact with the cardboard, and the limit spring 632 will be compressed, and the cardboard will move from the fixed part 52 to the movable part 51. And when the cylinder 481 is reciprocated, the telescopic end of the cylinder 481 will reciprocate and pull the squeezing plate 631 through the connecting rope 633, intermittently cancel the fixation of the cardboard in the storage bin 5, and then the cardboard will be replenished to the side of the movable part 51 in time. At the same time, in order to reduce the occurrence of the cardboard dumping in the storage bin 5, a push plate 54 is slidably connected in the storage bin 5, and a push spring 55 is fixedly connected to the push plate 54 and the end of the storage bin 5 away from the opening of the storage bin 5. The push spring 55 is used to push the cardboard to one side of the conveyor belt 1.

[0039] A limiting frame 7 is provided on one side of the conveying terminal of the conveyor belt 1, and the limiting frame 7 is set on the ground. Two groups of pulleys 71 are provided on the limiting frame 7, and each group of pulleys 71 includes a plurality of coaxially arranged pulleys 71 and a driving motor 72 for driving the pulleys 71 to rotate. The output shaft of the driving motor 72 is coaxially arranged with the corresponding pulley 71, and the driving motor 72 is installed on the limiting frame 7 and the output shaft of the driving motor 72 is passed through and fixedly connected to the plurality of coaxially arranged pulleys 71. A gap is left between two adjacent pulleys 71. The two groups of pulleys 71 are arranged up and down. A gap is left between the two groups of pulleys 71 for cardboard to pass through.

[0040] Thus, the cardboard detached from the conveyor belt 1 can enter the gap between the two sets of pulleys 71 and enter the device under the limit of the pulleys 71. At the same time, in order to improve the stability of the cardboard when it detaches from the conveyor belt 1, a third connecting rod 8 is provided at one end of the balance bar 42 near the conveying end of the conveyor belt 1, and the third connecting rod 8 is set at a right angle. One end of the third connecting rod 8 is inserted and slidably connected in the sliding hole 421 on the side of the balance bar 42 near the conveying end of the conveyor belt 1, and the other end of the third connecting rod 8 is fixedly connected to a feed plate 81, the end face of the feed plate 81 is parallel to the belt surface of the conveyor belt 1 and the feed plate 81 has a certain elasticity. A fourth limiting rod 82 is fixedly connected to the support plate 41, and the length direction of the fourth limiting rod 82 is perpendicular to the end face of the support plate 41. The third connecting rod 8 is inserted and slidably connected to the fourth limiting rod 82.

[0041] Furthermore, under the restriction of the fourth limiting rod 82 , the third connecting rod 8 can only rise or fall in a direction perpendicular to the upper end surface of the conveyor belt 1 .

[0042] Therefore, when the balance bar 42 swings, the third connecting rod 8 will move back and forth up and down under the restriction of the fourth limit rod 82, thereby driving the feeding paperboard to move up and down, and repeatedly abutting against the paperboard on the conveyor belt 1, so that the feeding paperboard can be close to the conveyor belt 1 during the movement toward the pulley 71, and the feeding plate 81 is used to press the paperboard between the conveyor belt 1 and the pulley 71.

[0043] The implementation principle of the embodiment of the present application is: start the conveyor belt 1, then start the cylinder 481, so that the cylinder 481 drives the balance rod 42 to swing, and then the abutment rod 61 will reciprocately abut with the movable part 51, and at the same time, the limit component 63 will reciprocate to cancel the restriction on the cardboard in the storage bin 5, so that multiple cardboards are placed on the conveyor belt 1 in sequence. Here, the number of cardboards falling on the conveyor belt 1 at one time can be adjusted by changing the length of the movable part 51.

[0044] Subsequently, the cardboard can be placed in the correct conveying position by the limit block 2 and the baffle plate while moving on the conveyor belt 1. At the same time, the balance bar 42 will exert a downward force on the cardboard through the cardboard feeding process during the swinging process, so that the cardboard can enter between the two sets of pulleys 71 on the limit frame 7 from the conveyor belt 1 more stably, and enter the cardboard film cutting machine under the restriction of the two sets of pulleys 71.

[0045] This embodiment also discloses a die-cutting machine.
