[0028] It should be known that the liquid silicone after completing injection molding usually has some excess material at the nozzle, so that manual cutting of the excess material is required; normally, manual cutting is performed by using scissors; the manual cutting has low production efficiency and the length of the cut product cannot be consistent, so that the quality of the product cannot be guaranteed and the scrap rate of the product is high.

[0029] Therefore, in the embodiment, the liquid silicone is cut by the adsorption assembly 3 and the cutting assembly 2 instead of manual cutting, the production efficiency is improved, the production quality of the product is effectively improved, and the fatigue of the workers during operation is reduced; the adsorption assembly 3 also limits the installation height of the product, so that the consistency of the cutting length of the product is guaranteed.

[0030] In the embodiment, as shown in Figure 1 and Figure 2 , the adsorption assembly 3 includes a first suction part 30, a second suction part 31, and a stripping cylinder 34; the stripping cylinder 34 is vertically fixedly installed on the rack 1, the first suction part 30 is vertically installed on the output end of the stripping cylinder 34, and the second suction part 31 is installed on the first suction part 30 as an adsorption end 35 with adjustable position, so that a cutting gap 350 is formed between the first suction part 30 and the second suction part 31; the stripping cylinder 34 is suitable for driving the first suction part 30 and the second suction part 31 to separate from the product.

[0031] It can be understood that the rack 1 is provided with a mounting hole and a mounting seat 33; the first suction part 30 and the second suction part 31 are suitable for vertical movement along the mounting seat 33 under the driving of the stripping cylinder 34. Specifically, the rack 1 is provided with a mounting hole and a mounting seat 33, the mounting hole and the mounting seat 33 are coaxially arranged; the stripping cylinder 34 is vertically fixedly installed on the rack 1, the first suction part 30 is vertically installed on the output end of the stripping cylinder 34, so that the stripping cylinder 34 can drive the first suction part 30 to move vertically; the second suction part 31 is installed on the first suction part 30 away from the connection end of the stripping cylinder 34 as an adsorption end 35 with adjustable position, and then the stripping cylinder 34 can drive the second suction part 31 to move vertically through the first suction part 30; after the cutting assembly 2 completes cutting of the product, only the stripping cylinder 34 needs to be started, the stripping cylinder 34 drives the second suction part 31 to move vertically downward, until the adsorption end 35 of the second suction part 31 is located in the mounting seat 33, the product can separate from the adsorption end 35.

[0032] In the embodiment, the first suction part 30 and the second suction part 31 are in communication; the adsorption assembly 3 further includes a connecting block 301 and an external pump body; the external pump body is connected to the first suction part 30 through the connecting block 301, and then the second suction part 31 is suitable for generating negative pressure under the driving of the external pump body.

[0033] Specifically, as shown in Figures 1 to 3 , the connecting block 301 is adapted to be installed in cooperation with the output end of the stripping cylinder 34; the connecting end of the first suction accessory 30 is connected in cooperation with the connecting block 301, and the connecting block 301 is provided with a connecting port 3010, and the connecting block 301 can be connected with the external pump body through the connecting port 3010, and the first suction accessory 30 is a hollow structure, and the external pump body can suck the first suction accessory 30 at this time; because the second suction accessory 31 is communicated with the first suction accessory 30, so that the second suction accessory 31 can generate negative pressure under the driving of the external pump body through the first suction accessory 30.

[0034] From the above, the cutting assembly 2 is multiple, and is circumferentially arranged on the side of the suction end 35 to cut the positioned product; it can be understood that the outer surface of the second suction accessory 31 is not provided with a ring groove along the circumferential direction of the suction end 35, and at this time, the cutting assembly 2 needs to abut the cutting end with the outer surface of the suction end 35 to complete the cutting of the product; if the cutting end of the cutting assembly 2 is in contact with the outer surface of the suction end 35 for a long time and applies a force, it may cause the outer surface of the suction end 35 to produce a cut mark.

[0035] Therefore, in the embodiment, as shown in Figure 3 and Figure 5 , the upper end of the second suction accessory 31 is provided with a column body with the same diameter as the first suction accessory 30, so that the product will be tightly attached to the column body and the outer surface of the first suction accessory 30 after being positioned; the cutting end of the cutting assembly 2 is located in the cutting gap 350 after completing the cutting of the product; it can be understood that the second suction accessory 31 is installed in cooperation with the first suction accessory 30, and the diameter of the installation position is smaller than the diameter of the first suction accessory 30 and the column body, so that the cutting end of the cutting assembly 2 will not be in contact with the second suction accessory 31 after completing the cutting of the product, and thus the outer surfaces of the first suction accessory 30 and the second suction accessory 31 will not produce a cut mark to prolong the service life. It should be known that the top of the second suction accessory 31 is provided with a suction port 310; the second suction accessory 310 is adapted to be communicated with the first suction accessory 30 through the suction port 310 to generate negative pressure to position the product.

[0036] It can be understood that the size of the product should be various; when cutting products of different sizes, the cutting position may be different, if the installation height of the second suction accessory 31 can be adjusted, the installation height of the product can be adjusted, and thus the cutting position of the product can be adjusted; therefore, in the embodiment, the second suction accessory 31 is adapted to be installed in the first suction accessory 30 through the position-adjustable limiting structure.

[0037] For the above-mentioned limiting structure, there are various structures that can be set, and in the embodiment, as shown in Figure 3 , the limiting structure includes a threaded hole 300 arranged on the side of the first suction accessory 30 and a bolt; the second suction accessory 31 is adapted to be fastened to the first suction accessory 30 through the threaded hole 300 and the bolt, thereby adjusting the installation height of the second suction accessory 31 relative to the first suction accessory 30. Specifically, when the second suction accessory 31 completes the adjustment of the installation height according to different sizes of products, the bolt and the threaded hole 300 are threadedly connected, and after being connected to a certain extent, the threaded end of the bolt can abut against the side of the second suction accessory 31 to fix the installation position of the second suction accessory 31; when the second suction accessory 31 needs to be adjusted again, the bolt only needs to be screwed again, so that the threaded end of the bolt is away from the second suction accessory 31, and the second suction accessory 31 can be moved, and when the second suction accessory 31 is adjusted to the required position, the bolt only needs to be tightened again, so that the threaded end abuts against the side of the second suction accessory 31 again.

[0038] In the embodiment, as shown in Figure 4 , the cutting assembly 2 includes a cutting piece 21 and a gas cylinder 20; the cutting piece 21 is installed in the gas cylinder 20 in a matched manner; the gas cylinder 20 is adapted to drive the cutting piece 21 to move towards the suction assembly 3.

[0039] Specifically, a pair of gas cylinders 20 are installed on the rack 1 in a matched manner, and the pair of gas cylinders 20 are equidistantly arranged along the circumferential side of the suction end 35; the output ends of the pair of gas cylinders 20 are directed towards the suction end 35; a fixed block 22 is installed on each output end of the pair of gas cylinders 20 to facilitate the connection of the cutting piece 21; the cutting piece 21 is fixedly installed on the fixed block 22, and the gas cylinder 20 drives the fixed block 22 to move, thereby driving the cutting piece 21 to move.

[0040] From the above, there are multiple cutting assemblies 2; for the setting of the number of cutting assemblies 2, as shown in Figure 1 and Figure 4 , in the embodiment, one pair is preferably adopted; the pair of cutting assemblies 2 are symmetrically arranged along the circumferential side of the second suction accessory 31.

[0041] As can be understood, the cutting assembly 2 needs to cut around the product; therefore, as shown in Figure 4 , in the embodiment, the cutting end of the cutting piece 21 is arranged in a semicircular shape.

[0042] In the embodiment, as shown in Figure 1 , the rack 1 is provided with a fixed plate 10 and a blanking plate 4; the fixed plate 10 is used for fixedly connecting with the stripping gas cylinder 34 in the embodiment; the blanking plate 4 plays a guiding role when the product completes cutting and positioning is released, so that the product that has completed cutting falls into the external frame under the guiding action of the blanking plate 4.

[0043] For the convenience of understanding, the overall working process of the present embodiment is described in detail below.

[0044] When the product needs to be positioned by the suction assembly 3, first, the product is sleeved on the first suction accessory 30 and the second suction accessory 31; then the external pump body is started, which will generate negative pressure on the connecting block 301, because the connecting block 301, the first suction accessory 30 and the second suction accessory 31 are communicated and the second suction accessory 31 is provided with a suction port 310, so that the second suction accessory 31 will generate negative pressure suction on the product to be cut, and then the product will be positioned and cannot be moved.

[0045] When the product needs to be cut after being positioned, first, the air cylinder 20 is started to drive the output end of the air cylinder 20 to move the cutting member 21 through the fixed block 22 towards the second suction accessory 31 until the cutting is completed; at this time, the cutting end of the cutting member 21 is located in the cutting gap 350 and does not contact the outer surface of the first suction accessory 30 and the second suction accessory 31.

[0046] When the product needs to be separated from the suction assembly 3 after being cut, first, the air cylinder 20 is started again to drive the output end of the air cylinder 20 to move the cutting member 21 away from the second suction accessory 31; then the material removal air cylinder 34 is started to drive the second suction accessory 31 to move vertically downward until the suction end 35 is located in the mounting seat 33; at this time, the product is no longer sleeved and the suction of the suction end 35 will fall to the discharging plate 4 and fall to the external frame under the guiding action of the discharging plate 4.

[0047] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application.
