Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to a pallet-mounted automatic louvered cutting machine. Background Technology

[0002] The production of tofu skin uses soybeans as raw material and involves seven core processes: First, carefully selected high-quality soybeans from Guanyun in northern Jiangsu or Northeast China are soaked in water to soften them, then ground into a paste using a stone mill. The paste is then boiled in a wood-fired stove at a controlled temperature, and coagulated using brine and calcium sulfate. Precise pressure is applied using wooden pressing tools to create the desired firmness, and then each sheet of wet tofu skin is manually peeled off. This technique, passed down from the Qianlong era of the Qing Dynasty, has been preserved through a family-based system, maintaining the purely handmade process. The finished product is renowned for its whiteness, fragrance, tenderness, glutinous texture, smoothness, and elasticity. During the processing of tofu skin, it needs to be cut.

[0003] For example, a bean curd skin cutting device with patent number CN219946447U has the following shortcomings in actual use:

[0004] The aforementioned device and food cutting devices based on the same principle cut food on the conveyor belt using a cutter. However, after the louvers are produced, they are in sheet form and stacked on a tray, making them quite heavy. Existing food cutting equipment suitable for assembly line operations requires the tray to be moved onto the conveyor belt for cutting. It is inconvenient to pull the tray full of louvers from the previous process onto the conveyor belt, and using separate handling equipment is costly. Summary of the Invention

[0005] In order to improve the technical problem that existing cutting equipment cannot actively pull the pallet, this application provides an automatic pallet-moving louver cutting machine.

[0006] The pallet-moving automatic louver cutting machine provided in this application adopts the following technical solution:

[0007] An automatic louver cutting machine with a pallet-moving mechanism includes a conveyor table and a pallet. The conveyor table includes two symmetrically distributed inner curved plates and two symmetrically distributed outer curved plates. The upper and lower ends of the inner and outer curved plates are of equal height, and a gap is provided between the outer and inner curved plates on the same side. A sliding frame is provided below the inner curved plate, and right-angle sliding parts are fixed to the upper ends of both sides of the sliding frame. The upper ends of the right-angle sliding parts are slidably disposed inside the outer curved plates. A driving mechanism is provided below the conveyor table to drive the sliding frame to move. Two pull rods are rotatably provided on one side of the sliding frame, and a pull pin is fixed to the end of the pull rod away from the sliding frame. Two pull holes matching the pull pins are provided on the pallet. First cylinders are symmetrically distributed on both sides of the conveyor table, and a cutter is installed on the upper end of the first cylinder. Several limit switches are provided below the conveyor table at equal intervals.

[0008] By adopting the above technical solution, during installation, the height of the control device is consistent with the height of the tray in the previous process. Pulling up the two pull rods and inserting the pull pins into the pull holes of the tray, the drive mechanism drives the sliding frame to move along the direction of the conveyor table, which can simultaneously move the tray and the louvers placed on it. The pause position is determined by the limit switch. When paused, the first cylinder drives the cutter to cut downwards, thereby achieving the automatic cutting effect of the louvers. There is no need for operators to move the tray, making it more convenient to use.

[0009] Preferably, the driving mechanism includes a rotating shaft rotatably disposed at both ends of the conveyor table, and a sprocket is installed at both ends of the rotating shaft. Two chains are installed on the sprockets and are symmetrically distributed. The upper end of the chain is located inside the outer curved plate and is fixedly connected to the upper end of the right-angle sliding member. A drive motor for driving the rotating shaft to rotate is installed at the side end of the conveyor table.

[0010] By adopting the above technical solution, the drive motor drives one of the rotating shafts to rotate, and then the overall drive is achieved through the transmission of the chain and sprocket. The forward and reverse rotation of the drive motor can control the forward and backward movement of the sliding frame.

[0011] Preferably, the bottom of the conveyor table is fixed with several equally spaced curved connecting rods, the two ends of which are fixed to two outer curved plates, and two support plates are fixed on the curved connecting rods, with the lower end of the chain located on the support plates.

[0012] By adopting the above technical solution, the upper end of the chain is supported by the outer curved plate and the lower end is supported by the support plate. In addition to transmitting power, the chain also needs to withstand vertical pressure. The support plate and the outer curved plate can share this load and prevent the chain from deforming, stretching or breaking due to excessive force.

[0013] Preferably, a mounting plate is fixed on the bending connecting rod, and a number of equally spaced long slots are opened on the mounting plate. The limit switch is located in the corresponding long slot, and two nuts are fixed on the limit switch, which are clamped on both sides of the mounting plate.

[0014] By adopting the above technical solution, the limit switch is fixed by two nuts. Therefore, after loosening the nuts, the limit switch can slide in the long slot, thereby changing the cutting position and making it convenient to adjust the cutting effect.

[0015] Preferably, a support frame is fixed to the upper end of the sliding frame, and a second cylinder is installed on the support frame, with the second cylinder arranged vertically.

[0016] By adopting the above technical solution, when the pallet is long, the pull rod can be placed in the gap between the outer and inner curved plates, the second cylinder can be extended, and the pallet can be hooked by the upward protruding part of the second cylinder, thereby driving the pallet to move and expanding the applicable range of the device.

[0017] Preferably, a protective net is provided above the conveyor table, and the protective net covers the outside of the cutter, and protrusions are provided on both sides of the protective net, with the first cylinder located inside the protrusions.

[0018] By adopting the above technical solution, the safety net prevents operators from accidentally touching the cutter and the first cylinder, thereby reducing the accident rate.

[0019] Preferably, the protective net has two symmetrically distributed handles on both sides, and the handles are located below the protective net. Two right-angled clamps are fixed to the outer side of the outer curved plate, and the bottom of the protective net is clamped to the inner side of the clamps.

[0020] By adopting the above technical solution, the protective net is supported by the clamps on both sides, and the protective net can be lifted up by the handles on both sides. Disassembly is simple and it is convenient to replace the cutter.

[0021] Preferably, a triangular inclined plate is provided below the conveyor table, and inclined guide surfaces are provided on both sides of the triangular inclined plate. The triangular inclined plate is fixed on one of the curved connecting rods, and the triangular inclined plate is located directly below the cutter. Two collection boxes are placed below the triangular inclined plate.

[0022] By adopting the above technical solution, scraps will be generated at the front and rear ends of the louver during cutting. These scraps will fall downwards after cutting and can be collected in two collection boxes by the triangular inclined plate for convenient centralized processing.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The pallet is hooked by two rotatable levers and pulled directly onto the conveyor table. The cutting position is positioned by the drive mechanism and limit switch. The first cylinder drives the cutter to cut at the cutting position. It is convenient to use and does not require operators to move the pallet or place the louvers. It also does not require additional handling equipment and has a low cost. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses a pallet-moving automatic louver cutting machine.

[0035] Example 1:

[0036] Reference Figures 1-4 An automatic louver cutting machine with pallet movement includes a conveyor table and a pallet 7. The conveyor table includes two symmetrically distributed inner curved plates 1 and two symmetrically distributed outer curved plates 2. The upper and lower ends of the inner curved plates 1 and the outer curved plates 2 are at the same height and provide support for the pallet 7. A gap is left between the outer curved plate 2 and the inner curved plate 1 on the same side.

[0037] Below the inner curved plate 1, a sliding frame 3 is provided. Right-angle sliding members 4 are fixed to the upper ends of both sides of the sliding frame 3. The upper ends of these right-angle sliding members 4 are slidably disposed inside the outer curved plate 2. A drive mechanism is provided below the conveyor table, which drives the sliding frame 3 to move.

[0038] Two pull rods 5 are rotatably mounted on one side of the sliding frame 3, and the pull rods 5 are located in the gap between the outer curved plate 2 and the inner curved plate 1. A pull pin 6 is fixed to the end of the pull rod 5 away from the sliding frame 3. Two pull holes adapted to the pull pins 6 are provided on the tray 7. In addition, first cylinders 26 are symmetrically mounted on both sides of the conveyor table, and cutters 27 are mounted on the upper end of the first cylinders 26. Several limit switches 8 are evenly distributed below the conveyor table for positioning the cutting position.

[0039] With the above settings, during installation, it is necessary to ensure that the height of the control device is consistent with the height of the tray 7 in the previous process. Pull up the two pull rods 5 and insert the pull pin 6 into the pull hole of the tray 7. Subsequently, the drive mechanism is activated, driving the sliding frame 3 to move along the conveyor table, thereby simultaneously moving the tray 7 and the louvers placed on it together.

[0040] Limit switch 8 is used to determine the pause position. When the preset pause point is reached, the first cylinder 26 drives the cutter 27 to move downward to cut, thereby realizing the automatic cutting of the louver.

[0041] Throughout the process, no operator is required to move the pallet 7, making it convenient to use. The pallet 7 is hooked onto the conveyor platform by two rotatable levers 5, and then the drive mechanism and limit switch 8 precisely position the cutting location. Finally, the first cylinder 26 drives the cutter 27 to complete the cutting. This not only eliminates the hassle of manual handling and louver placement but also eliminates the need for additional handling equipment, effectively reducing costs.

[0042] Reference Figure 2 and Figure 3 The specific structure of the drive mechanism is as follows: At both ends of the conveyor table, there are rotating shafts 9 respectively, and each shaft 9 has a sprocket 11 installed at both ends. Two symmetrically distributed chains 12 are mounted on the sprockets 11. The upper end of the chain 12 is located inside the outer curved plate 2 and is fixedly connected to the upper end of the right-angle sliding member 4.

[0043] A drive motor 10 is installed on the side of the conveyor table, which drives the rotating shaft 9 to rotate. In addition, several equally spaced curved connecting rods 13 are fixed to the bottom of the conveyor table, and the two ends of these curved connecting rods 13 are respectively fixed to two outer curved plates 2. At the same time, two support plates 14 are fixed to each curved connecting rod 13, and the lower end of the chain 12 is placed on the support plate 14 to provide support for the chain 12.

[0044] With the above setup, the drive motor 10 drives the sprocket 11 and chain 12 to rotate, and then the chain 12 pulls the sliding frame 3 to move, realizing the automatic movement of the louvers and tray 7. Moreover, the upper end of the chain 12 is supported by the outer curved plate 2, and the lower end is supported by the support plate 14, preventing the chain 12 from deforming, stretching or breaking due to excessive force, thus extending its service life.

[0045] refer to Figure 5 A mounting plate 15 is fixed to the bending connecting rod 13. The mounting plate 15 has several equally spaced elongated slots 16. Limit switches 8 are placed in the corresponding elongated slots 16, and each limit switch 8 is threaded with two nuts 17. These two nuts 17 are clamped on both sides of the mounting plate 15 to ensure that the limit switches 8 are installed securely.

[0046] With the above settings, the operator can fix the limit switch 8 at any position within the long slot 16, thereby determining the distance between the limit switches 8 and adjusting the cutting part and size of the louver, making it more convenient to use.

[0047] The implementation principle of this embodiment is as follows:

[0048] The sliding frame 3 is moved by the chain 12. The two pull rods 5 on the sliding frame 3 will pull the tray 7 onto the conveyor table. When the limit switch 8 is triggered during the movement, the movement will be paused. At this time, the first cylinder 26 will drive the cutter 27 to cut, realizing the automatic cutting effect of the louvers. Moreover, the chain 12 is equipped with a support structure (outer curved plate 2 and support plate 14) to prevent the chain 12 from deforming, stretching or breaking due to excessive force. In addition, the limit switch 8 can be adjusted in the long slot 16 to facilitate the adjustment of the cutting spacing and cutting position. During the cutting process, the operator does not need to move the tray 7 and the placed louvers. It is convenient to use and does not require additional handling equipment, resulting in low cost.

[0049] Example 2:

[0050] Reference Figure 4 A support frame 18 is fixed to the upper end of the sliding frame 3. A second cylinder 19 is installed on the support frame 18 and is arranged vertically.

[0051] With the above configuration, when the pallet 7 is long, the pull rod 5 can be placed in the gap between the outer curved plate 2 and the inner curved plate 1, the second cylinder 19 can be extended, and the pallet 7 can be hooked by the upward protruding part of the second cylinder 19 (the two ends of the pallet 7 are generally equipped with handles for carrying), thereby driving the pallet 7 to move and expanding the applicable range of the device.

[0052] The implementation principle of this embodiment is as follows:

[0053] After the sliding frame 3 moves to the edge, it has a long travel range and a large cutting range. The long tray 7 is moved by the second cylinder 19, which can ensure that the louvers on the tray 7 are fully cut.

[0054] Example 3:

[0055] Reference Figure 6 A protective net 20 is provided above the conveyor table, and the protective net 20 covers the outside of the cutter 27. The protective net 20 has protrusions 21 on both sides. The first cylinder 26 is located inside the protrusions 21. Two symmetrically distributed handles 23 are provided at the bottom of both sides of the protective net 20. Two right-angled clamping plates 22 are fixed on the outside of the outer curved plate 2, and the bottom of the protective net 20 is clamped inside the clamping plates 22.

[0056] With the above-mentioned setup, the protective net 20 can prevent operators from accidentally touching the cutter 27 and the first cylinder 26, preventing hand pinching and scratches, thereby reducing the accident rate and improving operational safety. When it is necessary to replace the cutter 27, the protective net 20 can be lifted directly through the handle 23, making disassembly simple.

[0057] Reference Figure 7 A triangular inclined plate 24 is provided below the conveyor table, and inclined guide surfaces are provided on both sides of the triangular inclined plate 24 to guide the material to both sides. The triangular inclined plate 24 is fixed on one of the curved connecting rods 13 and is located directly below the cutter 27. Two collection boxes 25 are placed below the triangular inclined plate 24.

[0058] With the above setup, scraps will be generated at the front and rear ends of the louver during cutting. These scraps will fall downwards after cutting and, guided by the triangular inclined plate 24, can be collected in two collection boxes 25 for convenient centralized processing.

[0059] The implementation principle of this embodiment is as follows:

[0060] The cutter 27 and the first cylinder 26 are protected by a detachable protective net 20 to prevent accidental injury to operators during equipment operation. The detachable structure also makes it easy for operators to replace the cutter 27. In addition, the scraps generated at the front and rear ends of the louver are collected in two collection boxes 25 for convenient centralized processing.

[0061] In summary, this device can hook the tray 7 with two pull rods 5, pull the tray 7 directly onto the conveyor table, and drive the louvers to move and cut. It does not require operators to move the tray 7 and the louvers, making it convenient to use. It also does not require additional handling equipment, resulting in lower costs.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
