[0084] The upper end of the motor bracket 201 has two elongated holes for connecting with the pad 202. The pad 202 has two threaded holes for fixing with screws and for fine-tuning the position of the motor bracket 201 on the pad 202, thereby tensioning the power belt 205.

[0085] Linkage assembly

[0086] like Figures 3-5 As shown, there are two sets of linkage assemblies, located on both sides of the lower end of the substrate, and the two sets of linkage assemblies penetrate the substrate. Taking the side of the substrate where the drive assembly is installed as an example, the linkage assembly mounted on the right side of the substrate is called the first linkage assembly, and the linkage assembly mounted on the left side of the substrate is called the second linkage assembly.

One end of the second rotating shaft 320 is installed on the second connecting rod 318 through the second oil-free bushing 319.

[0089] One end of each of the first rotating shaft 310 and the second rotating shaft 320 is provided with a groove. The groove is filled with lubricating oil. The first rotating shaft 310 and the second rotating shaft 320 rotate relative to their respective oil-free bushings. The rotation process is flexible and free of jamming. The wear of the parts is reduced.

[0090] Detection assembly

[0091] As shown in Figure 5 , the detection assembly and the driving assembly are located on the same side of the base plate. The detection assembly is arranged beside the first connecting rod assembly. The driving assembly is arranged beside the second connecting rod assembly.

[0092] On the substrate, an electric eye support 400 is arranged obliquely above the outer side of the first linkage assembly. The electric eye support 400 is in the shape of L, and a long hole is arranged on the electric eye support 400 to facilitate the installation and adjustment of an electric eye 401. A detection support 402 is arranged on the outer side of a second pulley 2062 connected with the first driving shaft 301. The detection support 402 is arranged in a specific shape, and when the second pulley 2062 rotates, the detection support 402 will pass through the detection range of the electric eye 401. After the electric eye 401 detects the detection support 402, it is recorded that the first driving shaft 301 rotates one round, and the signal is output to the control system.

[0093] Cutting knife assembly

[0094] The cutting knife assembly comprises a cutting knife support mounting member, two cutting knife fixing members, two cutting knife tensioning members and two cutting knives. The cutting knife assembly and the driving assembly are respectively located on two sides of the substrate.

[0095] As shown in Figure 6 , the cutting knife support mounting member comprises two support plates, a cutting substrate 500, two slide rail mounting plates, two slide rails, a visible plate 502 and two material guide plates. The support plate, the slide rail mounting plate, the slide rail and the material guide plate located on the same side as the first linkage assembly are respectively recorded as a first support plate 5011, a first slide rail mounting plate 5041, a first slide rail 5051 and a first material guide plate 5031. The support plate, the slide rail mounting plate, the slide rail and the material guide plate located on the same side as the second linkage assembly are respectively recorded as a second support plate 5012, a second slide rail mounting plate 5042, a second slide rail 5052 and a second material guide plate 5032.

[0096] The first support plate 5011 and the second support plate 5012 are arranged at the bottom end of the base plate and outside the two connecting rod assemblies, the cutting-off base plate 500 is arranged above the first support plate 5011 and the second support plate 5012 and is fixed by screws, the cutting-off base plate 500 is fixed and installed with the base plate by the two support plates, a U-shaped through slot is arranged in the middle of the cutting-off base plate 500, and the U-shaped opening faces the base plate, a visual plate 502 is arranged at the upper end of the cutting-off base plate 500, the cutting-off base plate 500 and the visual plate 502 are in contact and connection, and a convex-shaped through slot is arranged in the middle of the visual plate 502, the arrangement of the visual plate 502 can prevent hands from entering the two cutters and being injured, and the situation of the two cutters can be observed, two material guide plates, i.e., a first material guide plate 5031 and a second material guide plate 5032, are arranged at the convex-shaped through slot of the visual plate 502, the two material guide plates are oppositely arranged at the upper end of the convex shape, and the two material guide plates are used for guiding the material and preventing the material from running out of the two cutters. Two slide rail mounting plates are mounted at the bottom end of the cutting-off base plate 500 and are located above the two support plates, slide rails are mounted at the bottom end of the slide rail mounting plates, the slide rails are used for guiding the shearing movement of the two cutters on both sides, the slide rails need to be arranged perpendicularly to the support plates, and the slide rails are arranged in parallel to the side edges of the bottom end of the base plate, wherein the first slide rail mounting plate 5041 is mounted at the left lower end of the cutting-off base plate 500, the first slide rail 5051 is mounted at the lower end of the first slide rail mounting plate 5041, and the first slide block 5061 is slidably arranged on the first slide rail 5051; the second slide rail mounting plate 5042 is mounted at the right lower end of the cutting-off base plate 500, the second slide rail 5052 is mounted at the lower end of the second slide rail mounting plate 5042, and the second slide block 5062 is slidably arranged on the second slide rail 5052.

[0097] In addition, the first support plate 5011 and the second support plate 5012 are arranged with slots on both sides, which can facilitate the adjustment and installation of the fixing nails between the first cutter fixing seat 600, the front end mounting block 6001 and the first cutter mounting seat 602, and facilitate the adjustment and installation of the fixing nails between the second cutter fixing seat 610 and the second cutter mounting seat 612.

[0098] The two cutter fixing members need to fix the two cutters respectively, so the first cutter fixing member includes the first cutter fixing seat 600, the mounting block 6001, the first cutter mounting seat 602, the first cover plate 603, the first positioning pin 601, the third oil-free bushing 604 and the fourth oil-free bushing 605, and the second cutter fixing member includes the second cutter fixing seat 610, the second cutter mounting seat 612, the second cover plate 613 and the second positioning pin 611. Since the shapes of the first cutter 801 and the second cutter 802 are different, the first cutter fixing seat 600, the first cutter mounting seat 602, the second cutter fixing seat 610 and the second cutter mounting seat 612 are also different in shape.

[0099] As Figure 7aAs shown, the rear end of the first cutter fixing seat 600 is installed with the first sliding block 5061, which can slide on the first sliding rail 5051. The front end of the first cutter fixing seat 600 is inserted into the rear end groove of the mounting block 6001. The first cutter fixing seat 600 and the mounting block 6001 are connected together through the first rotating shaft 310. The middle position of the mounting block 6001 is provided with a circular groove, which is positioned with the first cutter mounting seat 602 through the first positioning pin 601. The mounting block 6001 provided at the front end of the first cutter fixing seat 600 and the first cutter mounting seat 602 can rotate through the first positioning pin 601. Both of them need to be fixed by screws, so that the first cutter 801 is arranged horizontally. The first rotating shaft 310 is installed in the middle through hole of the first cutter fixing seat 600. The first rotating shaft 310 passes through the front end through hole of the first cutter fixing seat 600 through two oilless bushings, i.e. the third oilless bushing 604 and the fourth oilless bushing 605, to connect the front end of the first cutter fixing seat 600 and the rear end of the mounting block 6001. The first cutter fixing seat 600 and the mounting block 6001 can rotate relative to the first rotating shaft 310, so that only the cutting edges of the two cutters contact, thereby realizing the change of the inclination angle ∠b during the movement of the two cutters.

[0100] The middle position of the first cutter mounting seat 602 is provided with a circular hole. The first positioning pin 601 is installed in the circular groove of the first cutter fixing seat 600 and the circular hole of the first cutter mounting seat 602 in interference fit, which can ensure accurate positioning. The first cutter 801 is installed on the first cutter mounting seat 602. Screws pass through the front end two side through holes of the first cutter mounting seat 602 and the rear end two side screw holes of the first cutter 801 respectively. The front end two side through holes of the mounting block 6001 provided at the front end of the first cutter fixing seat 600 correspond to the two outermost side through holes of the first cutter mounting seat 602, and are connected through corresponding screws. In addition, the first cover plate 603 is installed outside the first cutter fixing seat 600 to prevent the cutter sliding rail screws and top wires from falling onto the food and causing risks. It can also be used to shield the mounting hole, so that the appearance of the double-sided shearing cutting device is more beautiful.

[0101] Similarly, the second cutter fixing seat 610 is an integrally formed fixing seat. The second slider 5062 is installed on the second cutter fixing seat 610 and can slide on the second slide rail 5052. The second rotating shaft 320 is installed at the middle through hole of the second cutter fixing seat 610. The circular groove at the middle position of the front end plate of the second cutter fixing seat 610 is connected to the circular hole at the middle position of the second cutter mounting seat 612 through the second positioning pin 611. The second positioning pin 611 is used to realize the interference fit between the middle circular groove of the second cutter fixing seat 610 and the middle circular hole of the second cutter mounting seat 612. The second cover plate 613 is installed on the outside of the second cutter fixing seat 610, and the second cutter 802 is installed on the second cutter mounting seat 612.

[0102] The first cutting blade 801 is U-shaped, and the second cutting blade 802 is straight. The second cutting blade 802 is located on the upper surface of the first cutting blade 801, and the cutting edges of the first cutting blade 801 and the second cutting blade 802 are in contact. Figures 9a-9b As shown, the cutting edge of the first cutter 801 is its upper surface, as the cutting edge of the first cutter 801 is located on its upper surface; the cutting edge of the second cutter 802 is its lower surface, as the cutting edge of the second cutter 802 is located on its lower surface. The outer side of the first cutter 801 is connected to the first cutter mounting base 602, which is L-shaped; the outer side of the second cutter 802 is connected to the second cutter mounting base 612, which is T-shaped.

[0103] The cutter tensioning component includes a tension spring 700, a tension spring fixing seat 701, a bearing mounting plate 702, a flange bearing 703, and a fixed bearing 704, and is secured to both ends of the tension spring 700 by screws. Figures 7a-7b As shown, there are two sets of cutter tensioning components, which are respectively set on both sides of the two cutters. Since the first cutter 801 and the second cutter 802 are set in vertical contact, each set of cutter tensioning components needs to be set at the upper and lower ends of the two cutters respectively, without hindering the relative movement of the two cutters. The top two ends of the second cutter mounting base 612 are respectively provided with tension spring fixing seats 701. One end of the tension spring 700 is fixed to the tension spring fixing seat 701 by screws. On the two sides of the upper end of the second cutter mounting base 612, that is, at the two sides of the upper end of the T-shape, bearing mounting plates 702 are respectively inclinedly provided. One end of the bearing mounting plate 702 is installed on the second cutter mounting base 612 by screws through the fixing bearing 704. The other end of the bearing mounting plate 702 is installed on the flange bearing 703 by screws, which not only fixes the other end of the tension spring 700, but also makes the flange bearing 703 fit against the bottom of the first cutter 801. In this way, the tension of the tension spring 700 pulls the first cutter 801 and the second cutter 802 together. In addition, the position where the flange bearing 703 presses against the first cutter 801 should be vertical to the position of the blade of the second cutter 802.

[0104] The movement of the two cutters is relative movement, and the commonly used structure is that the two driving shafts are opposite, and the crank structure of the two cutters is centrally symmetric through design layout, so that the two driving shafts are the same, as shown in Figure 8 The advantage of this layout is that the belt pulley is not opposite in driving, and the structure is simple.

[0105] The two cutters are divided into two parts to realize shearing, and the cutter blade contact should be linear contact when the two cutters are cut, as shown in Figure 9b In the front view of the two cutters cutting, there is a real-time changing inclination angle ∠b of the two cutters in the movement process, and 1.5°> ∠b> 0°, wherein 1.5° is obtained through test, which can maximize the service life of the cutter blade of the two cutters. In the top view of the two cutters cutting, as shown in Figure 9a There is an inclination angle ∠a between the cutter blade of the first cutter 801 and the cutter blade of the second cutter 802, so that the shearing process can be realized in the movement process of the two cutters, as shown in Figure 9c The shearing process is as shown in Figure 9d .

[0106] In summary, the double-sided shearing cutting device provided by the application, the driving assembly transmits power to the two connecting rod assemblies through the belt pulley and the power belt 205, the two connecting rod assemblies are connected to the cutter fixing members and provide rotating force for the cutter fixing members, and the cutter fixing members can only move in the horizontal direction under the limitation of the cutter support mounting member; since one power belt 205 provides power for the driving shafts of the two connecting rod assemblies, the driving shafts of the two connecting rod assemblies are the same, but since the crank structures of the two connecting rod assemblies are centrally symmetric in shape, size and position, the two cutter fixing members move relatively, and then drive the two cutters to move relatively; in the relative movement process of the two cutters, the two material guide plates arranged on the cutter support mounting member guide the material into the middle of the two cutters, and the shearing process of the material is completed.
