DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figure 1 As shown, the lucky bag skin printing and cutting machine includes a crawler conveyor 1 and a printing device 9. The crawler conveyor 1 has a plurality of conveying crawlers 2. The printing device 9 is arranged above the crawler conveyor 1 through a frame 5. The number of printing devices 9 corresponds to the number of conveying crawlers 2. A displacement device 7 is arranged on the frame 5. The moving end of the displacement device 7 is connected to the printing device 9 to drive the printing device 9 to move back and forth in a straight line, so that when the printing device 9 prints on the tofu lucky bag skin, the printing device 9 can move with the tofu lucky bag skin on the crawler conveyor 1. A pressing and cutting device 8 for cutting the printed lucky bag skin is also arranged above the crawler conveyor 1.

[0030] In this embodiment, if Figure 8 As shown, the conveying track 2 includes a first track 201 and a second track 202, and there is a gap between the first track 201 and the second track 202. A plurality of groups of limit plates 203 are arranged on the first track 201 and the second track 202. The spacing between the plurality of groups of limit plates 203 is greater than the width of the tofu bag skin. The first track 201 and the second track 202 are synchronously driven, and the tofu bag skin is located on the first track 201 and the second track 202 at the same time. The pressing and cutting device 8 cuts the tofu bag skin through the gap between the first track 201 and the second track 202, and the limit plates 203 can play a positioning role for the tofu bag skin.

[0031] Among them, Figure 2As shown, the displacement device 7 includes a moving plate 705 and a rotating shaft 701 rotatably connected to both sides of the frame 5, one set of the rotating shafts 701 is connected to a servo motor 702, a belt body 703 is connected between the two sets of rotating shafts 701 through a pulley, the pulley is fixedly connected to the rotating shaft 701, both ends of the belt body 703 are connected to both sides of the moving plate 705, and slide rails 707 are fixed at both ends of the frame 5, and a slider 706 is slidably connected to the slide rail 707, and the slider 706 is fixedly connected to the moving plate 705. When the servo motor 702 is working, the rotating shaft 701 connected thereto will rotate, thereby driving the belt body 703 to transmit, and then the moving plate 705 moves under the action of the slider 706 and the slide rail 707, as shown in FIG. Figure 1 As shown, the number of printing devices 9 corresponds to the number of conveyor belts 2. The printing device 9 includes a cylinder 902 fixed on the supporting plate 6. A mounting plate 901 is fixed to the bottom output end of the cylinder 902. A plurality of fonts 903 are fixed to the bottom of the mounting plate 901. The supporting plate 6 is fixed to the top of the movable plate 705. A groove is provided on the movable plate 705. The cylinder 902 can drive the font 903 to pass through the groove and contact the tofu bag skin. Therefore, when the movable plate 705 moves, the printing device 9 can move accordingly. Therefore, when printing on the tofu bag skin, there is no need to stop the transportation of the tofu bag skin, thereby improving work efficiency.

[0032] The rotation speed of the servo motor 702 can be controlled, so that by controlling the working state of the servo motor 702, the moving speed of the printing device 9 corresponds to the moving speed of the tofu lucky bag skin on the crawler conveyor 1, and the maximum displacement length of the printing device 9 is greater than the displacement length required for printing, thereby ensuring that after printing on the tofu lucky bag skin, the printing device 9 can quickly move to the initial position and continue to print on subsequent tofu lucky bag skins to achieve uninterrupted work.

[0033] Among them, Figure 3 and Figure 7 As shown, a pressing plate 904 is provided at the bottom of the character mold 903, and a through hole 905 matching the character mold 903 is opened at the bottom of the pressing plate 904. The pressing plate 904 is connected to the mounting plate 901 through a spring buffer 906. The spring of the spring buffer 906 is located between the pressing plate 904 and the mounting plate 901. When the pressing plate 904 is pressed down and contacts the tofu lucky bag skin, the spring is deformed by the force applied by the pressing plate 904 and the mounting plate 901, so that the rod body of the spring buffer 906 rises, and then the mounting plate 901 can continue to descend, so that the character mold 903 passes through the through hole 905 and contacts the tofu lucky bag skin to print on the tofu lucky bag skin. At this time, the pressing plate 904 contacts the tofu lucky bag skin, thereby further positioning the tofu lucky bag skin to ensure that the tofu lucky bag skin will not be displaced during the printing process.

[0034] Among them, Figure 4As shown, the pressing and cutting device 8 includes two groups of vertical plates 801 arranged opposite to each other, and a plurality of rotating devices 802 are arranged between the two groups of vertical plates 801. The rotating device 802 includes a first axis 8021 rotatably connected to the vertical plate 801 and a plurality of pulleys 8022 fixed on the first axis 8021. The pulleys 8022 of the plurality of rotating devices 802 are connected by a pressure belt 806. The first axis 8021 of one group of rotating devices 802 is connected to a first motor 805. When the first motor 805 drives the corresponding first axis 8021 to rotate, the pressure belt 806 will be transmitted under the action of the plurality of rotating devices 802, and the pressure belt 806 will contact with the tofu bag skin. Therefore, the pressure belt 806 can limit the tofu bag skin.

[0035] like Figure 4 As shown, a second shaft 804 is rotatably connected between the two groups of vertical plates 801, and a plurality of slitting knives 803 are fixed on the second shaft 804. The plurality of slitting knives 803 are respectively aligned with the gaps formed by the first track 201 and the second track 202 of the plurality of conveyor tracks 2. The second shaft 804 is connected to a second motor 807. When the second motor 807 drives the second shaft 804 to rotate, along with the conveyor track 2, the slitting knives 803 will pass through the gap between the first track 201 and the second track 202 to cut the tofu lucky bag skin.

[0036] Among them, Figure 1 and Figure 5 As described, a fixed plate 10 is installed on the frame of the crawler conveyor 1, and several groups of unloading devices 3 are installed on the fixed plate 10. A gap is left between the unloading device 3 and the conveying crawler 2 for the lucky bag skin to pass through. The unloading device 3 includes two groups of L-shaped plates 301 arranged opposite to each other, a baffle 302 is fixed to the bottom of one side of the L-shaped plate 301, and a guide inclined plate 303 is fixed to the top of the baffle 302. The two groups of L-shaped plates 301 can accommodate tofu lucky bag skins, and the baffle 302 can prevent the tofu lucky bag skins from escaping from the unloading device 3 from the side during the falling process.

[0037] During operation, personnel can place the tofu lucky bag skin between the two L-shaped plates 301. At this time, the tofu lucky bag skin will fall on the conveyor belt 2 under the action of gravity. At this time, the limiting plates 203 on the first belt 201 and the second belt 202 will contact the side of the tofu lucky bag skin, so that the tofu lucky bag skin can overcome the resistance and move with the conveyor belt 2. In addition, the limiting plates 203 are used to drive the tofu lucky bag skin to move with the conveyor belt 2, so that the limiting plates 203 can accurately control the position of the tofu lucky bag skin on the conveyor belt 2, so that the printing device 9 can imprint the corresponding font to the required position of the tofu lucky bag skin.

[0038] Among them, Figure 1 and Figure 6As shown, a guide device 4 is also fixed on the frame of the crawler conveyor 1, and the guide device 4 includes a horizontal plate 402, and a plurality of first guide plates 401 and second guide plates 403 are staggeredly fixed on the bottom of the horizontal plate 402. As the tofu bag skin is conveyed on the conveying crawler 2, the adjacent first guide plates 401 and second guide plates 403 will guide the two sides of the tofu bag skin respectively, and then further correct the position of the tofu bag skin on the conveying crawler 2 to ensure that the position of the tofu bag skin will not be misplaced, so as to ensure that the printing device 9 can imprint the corresponding font to the required position of the tofu bag skin.

[0039] Among them, Figure 1 As shown, a finished product conveyor 11 is provided on one side of the crawler conveyor 1, and the finished product conveyor 11 is located at the discharge end of the pressing and cutting device 8. After the tofu bag skin is pressed and cut by the pressing and cutting device 8, it will continue to be conveyed on the finished product conveyor 11. At this time, personnel can manually remove unqualified products.

[0040] Working principle: first, the personnel place the tofu bag skin between the two L-shaped plates 301, and the tofu bag skin will fall on the conveyor belt 2 under the action of gravity. At this time, the limit plates 203 on the first belt 201 and the second belt 202 will contact the ends of the tofu bag skin, so that the tofu bag skin can overcome the resistance and move with the conveyor belt 2. During the movement, the adjacent first guide plates 401 and the second guide plates 403 will guide the two sides of the tofu bag skin respectively, and cooperate with the limit plates 203 to correct the position of the tofu bag skin on the conveyor belt 2 to ensure that the position of the tofu bag skin will not be misplaced, so as to ensure that the printing device 9 can imprint the corresponding font to the required position of the tofu bag skin. In the next step, the servo motor 702 is controlled to work so that the moving speed of the printing device 9 is consistent with that of the conveyor belt 2. The moving speed of the tofu bag skin on the crawler conveyor 1 corresponds to the speed of the tofu bag skin, and the cylinder 902 can drive the type mold 903 to descend and contact the tofu bag skin to print on the tofu bag skin. Therefore, when printing on the tofu bag skin, there is no need to stop the transportation of the tofu bag skin, thereby improving work efficiency. In the next step, when the first motor 805 drives the corresponding first axis 8021 to rotate, the pressure belt 806 will be transmitted under the action of several rotating devices 802, and the pressure belt 806 has a horizontal conveying part, which will contact with the tofu bag skin. Therefore, the pressure belt 806 can limit the tofu bag skin. During this process, the second motor 807 drives the second axis 804 to rotate, and the slitting knife 803 will cut the tofu bag skin through the gap between the first crawler 201 and the second crawler 202 to complete the printing and slitting operation of the tofu bag skin.

[0041] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
