DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Referring to Figures 1-5 A feeding mechanism of a die-cutting machine, comprising a bottom plate 1, a laterally movable mounting table 2 is arranged above the bottom plate 1, a stacking assembly is arranged on the mounting table 2, connecting plates 3 are fixedly installed on the left and right sides of the bottom plate 1, frame beams 4 are fixedly installed between the connecting plates 3, and a feeding assembly is arranged below the frame beams 4.

[0027] The stacking assembly comprises four material guide rods 5 fixedly installed on the mounting table 2, an object carrying plate 6 for placing paperboards is arranged between the material guide rods 5, a plurality of through slots 7 are formed in the object carrying plate 6, the object carrying plate 6 is slidably installed between the material guide rods 5 through the through slots 7, a vertical plate 8 is fixedly installed on the mounting table 2, a first motor 9 is fixedly installed on one side of the vertical plate 8, a first driving wheel 10 is fixedly installed at the output end of the first motor 9, a first driven wheel 11 is rotatably installed on the vertical plate 8, a first belt 12 is in transmission connection between the first driven wheel 11 and the first driving wheel 10, a fixed block 13 is fixedly installed on the first belt 12, and the fixed block 13 is fixedly connected with the object carrying plate 6.

[0028] The feeding assembly comprises a cross plate 14, two symmetrical connecting blocks 15 are fixedly installed on the lower surface of the cross plate 14, a friction roller 16 is rotatably installed between the connecting blocks 15, a second motor 17 is fixedly installed on the upper surface of the cross plate 14, a second driving wheel 18 is fixedly installed at the output end of the second motor 17, a second driven wheel 19 is fixedly installed at one end of the friction roller 16, and a second belt 20 is in transmission connection between the second driven wheel 19 and the second driving wheel 18.

[0029] When the work starts, the operator places a whole stack of paperboard on the loading plate 6, and the four corners of the paperboard are tightly surrounded by the four vertically erected guide rods 5, forming a stable guide space, which eliminates the risk of the paperboard pile collapsing forward due to the forward friction of the friction roller 16. When the paperboard is in place, the second motor 17 starts to drive the friction roller 16 to rotate through the second driving wheel 18 and the second belt 20. The rotating friction roller 16 contacts the uppermost paperboard and uses friction to send it horizontally to the die-cutting machine direction, completing the single paperboard feeding process. With each paperboard sent away, the height of the paper pile will slightly decrease. At this time, the first motor 9 starts to work, driving the first driving wheel 10 to rotate the first belt 12, and the fixed block 13 fixed on the belt moves, thereby driving the entire loading plate 6 and all the paperboards on it to precisely rise a small distance along the guide rod 5, so that the next paperboard can continue to maintain effective contact with the friction roller 16 until the paperboard on the station is completely sent.

[0030] Referring to Figure 5 , specifically: the stacking assembly is provided in two groups, two symmetrical support rods 21 are fixedly installed between the connecting plates 3, guide blocks 22 are slidingly installed on the support rods 21, a first air cylinder 23 is fixedly installed on one of the connecting plates 3, and the output end of the first air cylinder 23 is fixedly connected with the mounting table 2.

[0031] In the initial state, one group of feeding stations located directly below the friction roller 16 is in feeding, and the other group is in standby on the side, which can be used by the operator to pre-fill paperboard. When the paperboard in the feeding station is about to be used up, the first air cylinder 23 pushes the mounting table 2 to slide horizontally along the support rod 21, so that the fully loaded standby station is accurately moved to the position below the friction roller 16 to replace the feeding task. At the same time, the unloaded station moves out of the working area, facilitating the operator to prepare for the next time.

[0032] Referring to Figure 4 , specifically: a plurality of through grooves 7 are arranged in a ring array on the loading plate 6.

[0033] Referring to Figures 1-2 , specifically: a plurality of connecting holes 24 are formed in the mounting table 2, corresponding to the projection of the through grooves 7 on the mounting table 2. The bottom of the guide rod 5 is rotatably installed with a fixing screw 25 matched with the connecting hole 24. The guide rod 5 is connected with the connecting hole 24 on the mounting table 2 through the fixing screw 25 at the bottom, which not only ensures stable installation, but also facilitates disassembly, maintenance or layout adjustment to adapt to different sizes of paperboard requirements.

[0034] Referring to Figure 1 , Figure 3Specifically, the lower surface of the frame beam 4 is fixedly provided with a second air cylinder 26, and the output end of the second air cylinder 26 is fixedly connected with the horizontal plate 14. By starting the second air cylinder 26, the horizontal plate 14 and the whole feeding assembly can be driven to be finely adjusted up and down, so as to change the contact pressure of the friction roller 16 and the paperboard, so as to adapt to paperboards with different thicknesses or materials.

[0035] With reference to Figure 4 Specifically, the vertical plate 8 is fixedly provided with a guide rail 27 on one side, the guide rail 27 is slidably provided with a sliding block 28, and the sliding block 28 is fixedly connected with the object carrying plate 6.

[0036] Working principle: when the work starts, the operator places the whole stack of paperboard on the object carrying plate 6, and the four corners of the paperboard are tightly surrounded by the four vertically arranged guide rods 5, forming a stable guide space, which eliminates the risk of the paperboard stack being scattered and collapsed forward due to the forward friction of the friction roller 16. When the paperboard is in place, the second motor 17 is started to drive the friction roller 16 to rotate through the second driving wheel 18 and the second belt 20. The rotating friction roller 16 contacts the uppermost paperboard and uses the friction force to send it horizontally to the die-cutting machine direction, completing the feeding process of the single paperboard. Every time a paperboard is sent away, the height of the paperboard stack will slightly decrease. At this time, the first motor 9 starts to work to drive the first driving wheel 10 to rotate, and the fixed block 13 fixed on the belt moves, thereby driving the whole object carrying plate 6 and all the paperboards on it to accurately rise a small distance along the guide rod 5, so that the next paperboard can continue to maintain effective contact with the friction roller 16, until the paperboard at the work station is completely sent out.

[0037] The mechanism is provided with two independent stacking assemblies. In the initial state, one feeding station located directly below the friction roller 16 supplies the paperboard, and the other standby station located on the side can be pre-filled with paperboard by the operator. When the paperboard in the feeding station is about to be used up, the first air cylinder 23 pushes the mounting table 2 to slide horizontally along the support rod 21, so that the fully loaded standby station is accurately moved to the position below the friction roller 16 to replace the feeding task. At the same time, the unloaded work station moves out of the working area, which is convenient for the operator to prepare for the next feeding. This double-station rotating mechanism greatly improves the overall production efficiency.

[0038] In addition, by starting the second air cylinder 26, the horizontal plate 14 and the whole feeding assembly can be driven to be finely adjusted up and down, so as to change the contact pressure of the friction roller 16 and the paperboard, so as to adapt to paperboards with different thicknesses or materials. The guide rod 5 is connected with the connecting hole 24 on the mounting table 2 through the fixed screw 25 at the bottom, which not only ensures stable installation, but also facilitates disassembly, maintenance or layout adjustment to adapt to the needs of paperboards with different sizes.

[0039] The above merely describes a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, should be covered within the protection scope of the present application.
