[0033] The frame 18 is divided into two layers, a driven shaft 1 and a driving shaft 2 are arranged on both sides of the upper and lower layers of the frame, and the two ends of the driven shaft 1 and the driving shaft 2 are respectively connected to sprockets 12, and there are four groups of sprockets 12, and two bent plate chains 11 are connected to the sprockets 12; a control box 14 is arranged on the frame 18, and controls the servo motor 3 on the frame to be connected with other electrical devices;

[0034] The servo motor 3 is arranged at one end of the frame 18, and the servo motor 3 is connected to the synchronous wheel 17 through the synchronous belt 16, and the synchronous wheel 17 is connected to the driving shaft 2. The sprocket 12 drives the bending plate chain 11 to transmit, and there is a chain guide 10 under the bending plate chain 11. The chain guide 10 can ensure that the bending plate chain 11 does not fall downward.

[0035] like Figure 2 , Fig. 9As shown, the cutter device 7 includes a cylinder support frame 7-1, a double cylinder 7-2, a transverse support rod 7-3, a longitudinal support rod 7-4, a cylinder connection block 7-5, a cutter connection plate 7-6, and a cutter 7-7; the cylinder support frame 7-1 is fixed on the frame 18, and a transverse support rod 7-3 and a longitudinal support rod 7-4 are provided on the cylinder support frame 7-1. There are multiple double cylinders 7-2 and they are installed on the transverse support rod 7-3, and the spacing between each double cylinder 7-2 is the same as the center distance between two adjacent positioning devices 4, and each Each double cylinder 7-2 can be adjusted by ±5mm in the transverse direction of the cylinder support frame 7-1 through the longitudinal support rod 7-4, and the double cylinder 7-2 can be adjusted by ±5mm in the longitudinal direction through the transverse support rod 7-3. The number of double cylinders 7-2 on the cylinder support frame 7-1 is the same as the number of a group of positioning devices 4. A cylinder connection block 7-5 is installed under the double cylinder 7-2, and the cylinder connection block 7-5 is connected to the cutter connection plate 7-6. A group of cutters 7-7 are installed on the cutter connection plate 7-6. The adjustable stroke range of the double cylinder 7-2 in the cutter device 7 is 75-100mm, and the number and arrangement of the cutters 7-7 match the appearance shape and quantity of the product.

[0036] like Figure 3 As shown, the positioning device 4 is composed of two symmetrical positioning blocks 4-1. The shape of the two positioning blocks 4-1 after being assembled is an outer square and an inner circle. A groove matching the cutter structure is opened on the edge of the assembled inner circle. The width of the groove is 2-6mm and the depth is 1-5mm. The groove formed by the two positioning blocks is the same as the shape of the product to be cut. The inner circle diameter is 2-5mm larger than the product diameter. The two positioning blocks 4-1 are fixed on the bent plate chain 11 using threaded connection. The spacing between the inner circles of adjacent positioning devices is 15-20 times the pitch of the bent plate chain 11, and the positioning device 4 moves with the movement of the bent plate chain 11. The number of positioning devices 4 in a group is 3-5, and the number of positioning devices 4 in each group is the same. The spacing between two adjacent groups of positioning devices 4 is 65-70 times the pitch of the chain. The diameter of the sprocket 12 should be greater than or equal to 12 times the pitch of the bent plate chain 11 to ensure that the positioning device 4 can move smoothly without twisting when transitioning the corner.

[0037] like Figure 4As shown, the sprocket connected to the driven shaft is a driven sprocket at the lower position of the sprocket connected to the servo motor 3, and a tensioning mechanism 19 is provided at the driven sprocket. The tensioning mechanism 19 is fixed on the frame 18, including a base 19-1, a bearing seat 19-2, a driven sprocket 19-3, a first driven shaft 19-4, a single-head bolt 19-5, a hexagonal nut 19-6, a sleeve 19-7, and a compression spring 19-8; a compression spring 1 is provided between the base 19-1 and the bearing seat 19-2. 9-8, the single-head bolt 19-5 passes through the compression spring 19-8 and is fixed on the base 19-1, the single-head bolt 19-5 is installed with a bearing seat 19-2, a shaft sleeve 19-7 is provided above the bearing seat 19-2, the hexagonal nut 19-6 is connected to the single-head bolt 19-5 and is located above the shaft sleeve 19-7; the compression spring 19-8 supports the first driven shaft 19-4, causing it to have a tendency to deviate outward, and the chain has a tendency to deviate inward during movement, thereby achieving tensioning.

[0038] like Figure 1 , Figure 5 As shown, the blocking plate 6 is arranged directly below the cutting device 7, and a plurality of groups of slots are arranged on the blocking plate 6. The center distance between any two slots is the same as the center distance between any two cutters 7-7 of the cutting device 7, and the number of slot groups passing through the cutter above it also needs to match the number of groups required to be cut off by the product. The width of the cutting slot is 5-8mm, and its function is that when the cutter moves upward after cutting, it prevents the product from moving upward with the cutter.

[0039] like Figure 6 , Figure 7 As shown, the W-shaped support plate 9 is installed directly below the positioning device 4, and the cut edge shape of the support plate is a corrugated shape composed of multiple continuous W-shapes. The angle range of the W-shape is 120°-150°, in order to reduce the resistance between the product and the support plate when traveling. The corrugation of the support plate should not be too wide, the width of one cycle is 20-30mm, and the height range is 3-5mm. If it is too wide, part of the cutter will not be able to cut the support plate, so that the overall product is not cut thoroughly.

When they are opened, they are in the appearance shape of the product. The size of the opening and closing plates 20 when opened is 8mm larger than the size of the product, so that the product can fall vertically to the bottom; the adjustable stroke range of the guide rod cylinder 15 in the blanking device 5 is 25-50mm.

[0041] Principle: Put the cakes into the positioning device 4, and feed them in groups according to the number of cutters of the cutter device 7 (supported by a W-shaped support plate below). After being cut by the cutter device, they are transported to the top of the drop device. The drop device is opened and the cakes fall steadily.

[0042] Example 2

[0043] Use multi-station automatic cutting and blanking equipment to cut (the product shape is circular with a diameter of 160mm, and the product needs to be divided into 10 equal parts), place the product on the positioning device 4, and the distance between two adjacent products is 16 times the length of the five-point chain. After the product is placed, the sprocket rotates and the product moves forward. When it reaches the cutter station, multiple groups of cylinders drive the cutter to move downward to cut the product. After cutting, the sprocket rotates to continue to drive the product to move, and the opening and closing plate moves to the blanking position to open and drop the product.

[0044] Example 3

[0045] Use a multi-station brown sugar pastry cutting machine to cut (the product is a 150x150 rectangle and needs to be divided into 5 equal parts vertically), place the product on a group of positioning devices 4 at the front end, the distance between two adjacent products in a group of positioning devices 4 is 16 times the length of the five-point chain, after the product is placed, the sprocket rotates, and the product moves forward. When it reaches the cutter station, multiple groups of cylinders drive the cutter to move downward to cut the product. After cutting, the sprocket rotates to continue to drive the product to move, and moves to the drop location, the opening and closing plate opens to drop a group of products.

[0046] The protection scope of the present invention is not limited to the above-mentioned embodiments.
