[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, mobile phone pads, etc. Die-cutting machines use steel blades, hardware molds, and steel wire (or templates carved from steel plates) to apply a certain pressure through the printing plate to cut printed materials or cardboard into a certain shape.

[0003] Application number CN208714161 U discloses an automatic material receiving device for a rotary die-cutting machine, including a feeding mechanism, a first cutting mechanism, a second cutting mechanism, a main lifting mechanism, an adhesive applicator, a material pressing mechanism, and a third drive mechanism. This automatic material receiving device for a rotary die-cutting machine can achieve online material receiving without stopping the machine, and the receiving quality is high. It solves the problems of frequent and loose material receiving by manual methods, thereby improving production efficiency and reducing production costs. However, in practical use, the structural design of this application is very complex, which not only increases the machine manufacturing cost but also increases the difficulty of future maintenance. These two reasons limit its acceptance to large companies and manufacturers. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] An automatic material receiving mechanism for a rotary die-cutting machine includes a material receiving mechanism, a table changing mechanism, and a scraping mechanism. The material receiving mechanism includes a chassis, two triangular limiting seats connected to the top of the chassis, a turntable movably installed between the two triangular limiting seats, and multiple support platforms connected to the top of the turntable. The table changing mechanism includes a motor embedded in the top of the chassis, a crank connected to the output shaft of the motor, a deflector plate movably sleeved on the top of the crank, and a guide rod slidingly penetrating the top of the deflector plate. The deflector plate is movably engaged with one of the support platforms. The scraping mechanism includes a top shell connected between the two triangular limiting seats and a scraper plate connected to the top shell. The top of the guide rod is fixedly connected to the top of the inner cavity of the top shell.

[0007] By adopting the above technical solution, the motor output shaft drives the crank to rotate slowly, and then the crank drives the actuating plate, which is limited by the guide rod, to rotate. Every time the actuating plate rotates once, it drives a support platform to rotate. When the product on the support platform passes the opening position, it is scraped off by the scraper. This working mode can not only make the products on the support platform accumulate in a fixed number, but also realize the unmanned material receiving, thus improving the comfort of using this device.

[0008] In a preferred embodiment, the present invention can be further configured such that: the turntable is movably sleeved on the outside of the motor body, the center of the turntable is vertically coaxial with the center of the chassis, and the bottom of the turntable is in contact with the top of the chassis.

[0009] In a preferred embodiment, the present invention can be further configured as follows: multiple support platforms are equally spaced and arranged in a ring, and the support platforms are T-shaped.

[0010] In a preferred embodiment, the present invention can be further configured such that: the top of the crank is in contact with the bottom of the actuating plate, the bottom of the crank is in contact with the top of the turntable, and the length of the crank is equal to the distance between two adjacent support platforms.

[0011] In a preferred embodiment, the present invention can be further configured such that the tops of multiple support platforms are located on the same horizontal plane, and the bottom of the scraper is flush with the top of the support platform.

[0012] In a preferred embodiment, the present invention can be further configured such that: an opening is provided on the support platform, and the scraper is located on one side of the opening.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] In this invention, the motor output shaft drives the crank to rotate slowly, and then the crank drives the actuating plate, which is limited by the guide rod, to rotate. Every time the actuating plate rotates once, it drives a support platform to rotate. When the product on the support platform passes the opening, it is scraped off by the scraper. This working mode can not only make the products on the support platform accumulate in a fixed number, but also realize the unmanned material receiving, thus improving the comfort of using this device.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of an automatic material receiving mechanism for a circular die-cutting machine.

[0028] Example 1:

[0029] Combination Figure 1-5 As shown, the present invention provides an automatic material receiving mechanism for a circular die-cutting machine, including a material receiving mechanism 100, a table changing mechanism 200, and a scraping mechanism 300. The material receiving mechanism 100 includes a chassis 110, two triangular limiting seats 120 connected to the top of the chassis 110, a turntable 130 movably installed between the two triangular limiting seats 120, and a plurality of material support platforms 140 connected to the top of the turntable 130.

[0030] A platform changing mechanism 200 includes a motor 210 embedded in the top of the chassis 110, a crank 220 connected to the output shaft of the motor 210, a deflector plate 230 movably sleeved on the top of the crank 220, and a guide rod 240 slidably passing through the top of the deflector plate 230. The deflector plate 230 is movably engaged with a material support platform 140.

[0031] The scraping mechanism 300 includes a top shell 310 connected between two triangular limiting seats 120, a scraper 320 connected to the top shell 310, and the top end of the guide rod 240 is fixedly connected to the top of the inner cavity of the top shell 310.

[0032] Furthermore, the turntable 130 is movably sleeved on the outside of the motor 210 body, the center of the turntable 130 is vertically coaxial with the center of the chassis 110, and the bottom of the turntable 130 is in contact with the top of the chassis 110. The layout design of the turntable 130 allows it to rotate flexibly and smoothly.

[0033] Furthermore, multiple support platforms 140 are arranged in a ring with equal spacing. The support platforms 140 are T-shaped. The layout design of the support platforms 140 ensures the aesthetics of the device. On the other hand, the orderly arrangement allows the actuating plate 230 to drive each support platform 140 to rotate.

[0034] Furthermore, the top of the crank 220 is in contact with the bottom of the actuating plate 230, the bottom of the crank 220 is in contact with the top of the turntable 130, and the length of the crank 220 is equal to the distance between two adjacent support platforms 140. The length of the crank 220 is designed so that the crank 220 can engage with a support platform 140 every time it rotates, and then drive the support platform 140 to rotate.

[0035] Example 2:

[0036] Combination Figure 1-4 As shown, based on Embodiment 1, the tops of multiple support platforms 140 are located on the same horizontal plane, and the bottom of the scraper 320 is flush with the top of the support platform 140. The size design of the multiple support platforms 140 and the scraper 320 ensures that each support platform 140 will not be blocked by the scraper 320 when it rotates, while the scraper 320 can scrape off all the products on the support platform 140.

[0037] Example 3:

[0038] As shown in Figure 3, in the above embodiment, the support platform 140 has an opening 400, and the scraper 320 is located on one side of the opening 400. The opening 400 provides conditions for the product to fall from the support platform 140.

[0039] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the chassis 110 is fixed on one side of the circular die-cutting machine, and then the motor 210 is started. The output shaft of the motor 210 drives the crank 220 to rotate slowly. Then the crank 220 drives the actuating plate 230, which is limited by the guide rod 240, to rotate. Every time the actuating plate 230 rotates once, it drives a support platform 140 to rotate. Then, when the product on the support platform 140 passes the opening 400, it is scraped off by the scraper 320. This working mode can not only make the product on the support platform 140 accumulate in a fixed number, but also realize unmanned material unloading, which improves the comfort of using this device.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
