Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to an automatic louver cutting machine with a movable blade. Background Technology

[0002] In the food processing industry, food cutting equipment is a key piece of equipment for improving production efficiency and product standardization. With technological advancements, modern food cutting equipment integrates automated control, high-precision blades, and intelligent sensing technology, enabling rapid and precise cutting of different shapes and sizes while ensuring food hygiene and safety, effectively reducing production costs, and becoming an indispensable piece of equipment in the food processing industry.

[0003] For example, a food cutting device for food production, patent number CN222115291U, has the following shortcomings in actual use:

[0004] The aforementioned device features a cleaning structure where two scrapers contact the sides of the cutting blade. After the cutting blade completes its cut, it rises under the action of a cylinder, and the two scrapers scrape the sides of the cutting blade to remove food residue. The rubber material reduces wear on the cutting blade. Two sliding sliders can be used to adjust the distance between the scrapers and the cutting blade to accommodate foods of different viscosities and blade sizes. When the two adjusting plates are moved away from the cutting blade, it is easy to replace the cutting blade. However, the power mechanism of the aforementioned device, as well as many existing cutting devices, is located above the cutting blade. Although it can achieve the cutting function, the height makes the installation and maintenance of the cylinder or hydraulic cylinder inconvenient. Summary of the Invention

[0005] To address the technical problem of inconvenient installation and maintenance of existing food cutting devices, this application provides a knife-moving automatic louver cutting machine.

[0006] The automatic louver cutting machine with a movable blade type provided in this application adopts the following technical solution:

[0007] An automatic louver cutting machine with a movable blade includes a support table and a material plate placed on the support table. Two symmetrically distributed channel steel bars are fixed on both sides of the lower part of the support table, and the opening direction of the channel steel bars is outward. Two mounting parts are provided on both sides of the support table. Rollers are rotatably installed on the side end of the mounting parts, and the rollers are rolled inside the corresponding channel steel bars. A U-shaped connecting rod is provided between the two mounting parts. A vertically arranged cylinder is installed on the mounting parts, and a cutter is installed on the piston end of the two cylinders. A protective cover is provided on the outside of the cutter. A drive mechanism for driving the mounting parts to move along the channel steel bars and several equally spaced limit switches are provided below the channel steel bars.

[0008] By adopting the above technical solution, after the large louvers are produced and formed, they are supported and transported by a material plate. The material plate is placed on the support table, and then the drive mechanism drives two mounting parts to move along the channel steel bar. When the limit switch is triggered, the drive mechanism stops, and the cylinder drives the cutter to descend, thus achieving cutting. This process is repeated until the large louvers are cut into small louvers of a certain specification. Moreover, both cylinders are located on the side of the support table, with no obstruction on their outer side and a low height, making assembly and maintenance more convenient.

[0009] Preferably, each of the channel steel bars has a short channel steel bar with an outward opening fixed below it, and the lower side wall of one of the short channel steel bars has several long slots distributed at equal intervals, and the limit switch is clamped and fixed in the long slot at the corresponding position by two nuts.

[0010] By adopting the above technical solution, the limit switch is fixed by two nuts. Loosening the nuts allows the limit switch to slide in the long slot, thereby adjusting the cutting position of the cutter. It can cut louvers of different specifications and is easy to operate.

[0011] Preferably, the drive mechanism includes two sprockets, which are rotatably connected to both ends of another short channel steel. A chain is installed between the two sprockets. A drive motor is installed inside the short channel steel to drive one of the sprockets to rotate. A support rod is fixed inside the U-shaped connecting rod and is connected to the chain.

[0012] By adopting the above technical solution, the drive motor drives the sprocket to rotate, which in turn drives the chain to run. The support rod moves with the chain, and the reciprocating movement of the two mounting parts is controlled by the forward and reverse rotation of the drive motor.

[0013] Preferably, the protective cover includes a support frame, which is sleeved on the outside of the cutter. Both sides of the support frame are provided with protrusions that match the outer edge of the mounting component. A triangular block is fixed on the upper surface of the protrusion, and the triangular block is located at the corner of the protrusion. A protective net is fixed on the upper end and both sides of the support frame.

[0014] By adopting the above technical solution, the protruding part fits perfectly on the outside of the mounting part, which can drive the support frame to move horizontally, and the triangular block rests on the corner of the mounting part to provide support for the entire support frame. When disassembling and assembling the cutter, the protective cover can be removed by simply looking upwards, which is convenient to operate.

[0015] Preferably, a reinforcing rod is fixed between the legs of the supporting table, and a material box is placed on top of the reinforcing rod.

[0016] By adopting the above technical solution, when cutting louvers, it is necessary to cut off the uneven parts at both ends. At this time, a small amount of louvers cut off from both ends can be placed in the material box nearby for easy recycling.

[0017] Preferably, one end of the support table is provided with a plurality of equally spaced positioning holes, a baffle is provided on the support table, and a positioning pin matching the positioning hole is provided at the bottom of the baffle, and the positioning pin is inserted into the positioning hole at the corresponding position, and the end of the material plate abuts against the baffle.

[0018] By adopting the above technical solution, the specifications of the same batch of louvers are basically the same. When cutting, the baffle is inserted into the positioning hole at the appropriate position, which can play a certain positioning role for the material plate during subsequent cutting. The side end of the material plate is then placed against the baffle, making the operation of placing the material plate faster and more convenient.

[0019] Preferably, a cover cloth is fixed to one side of the baffle, and the cover cloth is laid above the positioning hole away from the material plate.

[0020] By adopting the above technical solution, after the baffle is placed, the positioning hole on one side of the baffle is covered by a cover cloth. During cutting, the positioning hole on the other side is covered by a material plate, which can prevent the fragmented louver scraps from falling into the positioning hole and making it difficult to clean.

[0021] Preferably, each of the mounting components has at least two rollers installed on it.

[0022] By adopting the above technical solution, if only one roller is used on one side, tilting and jamming may occur when the two mounting parts move. Having at least two rollers on one side can reduce the problem of asynchronous movement of the mounting parts and improve the smoothness of device operation.

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

[0024] 1. The louvers are cut by the retraction of cylinders on both sides of the support table. The movement of the cutter is controlled by the drive mechanism, and the cutting position is positioned by the limit switch. Taking advantage of the flexible nature of the louvers, the cylinders are installed at a low position, and the cutting force is provided by the retraction. Moreover, the cylinders are not obstructed from the outside, making assembly and maintenance more convenient. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] This application discloses a tool-moving automatic louver cutting machine.

[0034] Example 1:

[0035] Reference Figure 1 , Figure 2 An automatic louver cutting machine with a movable blade includes a support table 1. Reinforcing rods 20 are connected to the legs of the support table 1, and a material box 21 is placed on the reinforcing rods 20. A material plate 2 is placed on the support table 1. Two outward-facing channel steel bars 3 are symmetrically fixed on both sides below the support table 1. Each side of the support table 1 has a mounting component 4, with rollers 5 rotatably mounted on their sides. These rollers 5 are respectively placed inside the corresponding channel steel bars 3 and can roll along the channel steel bars 3. The two mounting components 4 are connected by a U-shaped connecting rod 6. Each mounting component 4 has a vertically mounted cylinder 7, and the piston ends of the two cylinders 7 are connected to a cutter 8. A protective cover is also provided on the outside of the cutter 8. Furthermore, a drive mechanism is arranged below the channel steel bars 3 to drive the mounting components 4 to move along the channel steel bars 3, and several equally spaced limit switches 9 are also provided.

[0036] With the above setup, after the large louvers are manufactured, they are placed on the material plate 2 for loading and handling. The material plate 2 carrying the louvers is placed on the support table 1, and then the drive mechanism is activated, moving the two mounting components 4 along the channel steel strip 3. When the mounting component 4 touches the limit switch 9, the drive mechanism stops. At this time, the cylinder 7 drives the cutter 8 to descend, cutting the louvers. After one cut, the above process is repeated until the large louvers are cut into smaller louvers that meet the specifications. The scraps cut off from both ends of the louvers can be directly placed into the material box 21. Furthermore, both cylinders 7 are located on the side of the support table 1, with no obstructions on the outside and a low height, greatly facilitating assembly and maintenance.

[0037] Reference Figure 3 , Figure 4 Below the two channel steel bars 3, short channel steel bars 10 with outward openings are fixed respectively. Several long slots 11 are evenly spaced on the lower side wall of one of the short channel steel bars 10. Limit switches 9 are fixed in the corresponding long slots 11 by clamping with two nuts. The drive mechanism is located on the other short channel steel bar 10, with two sprockets 12 rotatably connected to both ends of the short channel steel bar 10, and a chain 14 installed between the two sprockets 12. A drive motor 13 is installed inside the short channel steel bar 10 to drive one of the sprockets 12 to rotate. In addition, a support rod 15 is fixed inside the U-shaped connecting rod 6, and this support rod 15 is connected to the chain 14.

[0038] With the above setup, the limit switch 9 is fixed with two nuts. When it is necessary to adjust the cutting position of the cutter 8 to cut louvers of different specifications, simply loosen the nuts, and the limit switch 9 can be easily slid within the long slot 11, making operation simple and quick. After the drive motor 13 starts, it will drive the sprocket 12 to rotate, thereby driving the chain 14 to run. Since the support rod 15 is connected to the chain 14, it will move synchronously with the movement of the chain 14. By rotating the drive motor 13 forward and reverse, the reciprocating movement of the two mounting parts 4 can be realized. The two short channel steels 10 are respectively used to install different components, working together to achieve the effect of movement and positioning. The structure is simple, and assembly and maintenance are convenient.

[0039] refer to Figure 5 The protective cover includes a support frame 16 as an internal frame. The upper end and both sides of the support frame 16 are fixed with protective nets 19. The support frame 16 covers the outside of the cutter 8. Both sides of the support frame 16 are provided with protrusions 17 that match the outer edge of the mounting part 4, providing sufficient length for the lifting and lowering of the cutter 8. Triangular blocks 18 are fixed on the upper surface of the protrusions 17, and the triangular blocks 18 are located at the corners of the protrusions 17.

[0040] With the above configuration, the protective cover is fitted over the outside of the cutter 8, which improves the protection effect when the cutter 8 moves up and down. The protruding part 17 fits perfectly over the outside of the mounting part 4, ensuring that the protective cover can move with the translation of the mounting part 4. The triangular block 18 rests on the corner of the mounting part 4, providing support for the entire support frame 16. The protective cover can be removed by lifting it up, which facilitates the disassembly and assembly of the cutter 8 and makes it easy to clean the cutter 8.

[0041] The implementation principle of this embodiment is as follows:

[0042] On the two short channel steels 10, one is equipped with a chain 14 to drive the cutter 8 to move, and the other is equipped with a limit switch 9 to position the cutting position. Two cylinders 7 drive the cutter 8 to descend, achieving the effect of cutting louvers. Moreover, the two cylinders 7, the limit switch 9 and the drive motor 13 are all located on the side of the support table 1, with a low height, making it more convenient to assemble the equipment and carry out maintenance.

[0043] Secondly, a protective cover is provided on the outside of the cutter 8 to cover the cutter 8 and improve the protection effect. The protective cover fits perfectly on the outside of the mounting part 4 and can move with the mounting part 4. The triangular block 18 on the protective cover rests on the corner of the mounting part 4 to support the protective cover. When assembling or disassembling the cutter 8, the protective cover can be removed by simply looking upwards, which is convenient.

[0044] Example 2:

[0045] refer to Figure 6 The difference between this embodiment and Embodiment 1 is that: a baffle 23 is provided on the tabletop of the support table 1, and a positioning pin 24 is provided at its bottom. Several positioning holes 22 are evenly distributed at one end of the tabletop of the support table 1, which cooperate with the positioning pins 24 to fix the baffle 23. When the material board 2 is placed on the support table 1, its end will tightly abut against the baffle 23. In addition, a cover 25 is fixed to one side of the baffle 23, which naturally lies above the positioning holes 22 on the side away from the material board 2, providing a certain degree of protection.

[0046] With the above setup, since the specifications of louvers in the same batch are roughly the same, the position of the material plate 2 is basically fixed each time it is cut. After the material plate 2 is placed for the first time, simply insert the baffle 23 into the positioning hole 22 at the appropriate position so that the baffle 23 contacts the end of the material plate 2. During subsequent cutting, the baffle 23 can then position the material plate 2. In this way, each time the material plate 2 is placed, it is only necessary to align its side end with the baffle 23. The operation is quick and convenient. Moreover, after the baffle 23 is placed, the positioning hole 22 on one side of the baffle 23 is covered by the cover cloth 25. During cutting, the positioning hole 22 on the other side is covered by the material plate 2, which can prevent scraps of louver material from falling into the positioning hole 22 and making it difficult to clean.

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

[0048] The baffle 23 is fixed by the positioning hole 22, and the baffle 23 is used to position the louvers to be cut in the same batch. This eliminates the need for the operator to observe the position of the material plate 2 each time, thus improving work efficiency. In addition, the empty positioning hole 22 is partially covered by the material plate 2 and partially covered by the cover cloth 25, which can prevent the fragments of louver scraps from falling into the positioning hole 22 and making it difficult to clean.

[0049] In summary, this device can support the retraction of cylinders 7 on both sides of the table 1 to cut the louvers. The cylinders 7 are installed in a low position and are not obstructed externally, making assembly and maintenance more convenient.

[0050] 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.
