Description

Technical Field

[0001] The present invention relates to the technical field of non-standard automated design, and in particular to a hollow soft rubber strip cutting device and a cutting method thereof. Background Art

[0002] like Figure 1 As shown, it is a structural diagram of a hollow soft rubber strip 10. The hollow soft rubber strip 10 of this structure has a hollow cavity 11, and the hollow cavity 11 extends along the extension line of the hollow soft rubber strip 10. In the actual processing process, the hollow soft rubber strip 10 needs to be cut into several small sections.

[0003] Since the hollow soft rubber strip 10 is elastic and hollow, during the cutting process, it will be depressed by the downward pressure of the cutting knife (such as Figure 2 As the hollow soft rubber strip 10 sinks inward, the shape of the end to be cut will be deformed, resulting in unevenness of the end to be cut after cutting, affecting product quality.

[0004] In addition, the hollow soft rubber strip 10 needs to be continuously transported to the cutting position by the relevant conveying mechanism for cutting. Since the hollow soft rubber strip 10 is elastic, during the transportation process, the extension line direction of the hollow soft rubber strip 10 is easily bent by the force and thus bounces (such as Figure 3 As shown), the conveying positioning is inaccurate, which affects the product quality. In the design process of the non-standard automation device for the hollow soft rubber strip 10, how to design a more concise and efficient mechanism to convey the hollow soft rubber strip 10 is a problem that needs to be considered.

[0039] like Figure 4 and Figure 5 As shown, the present invention discloses a hollow soft rubber strip cutting device 20 for cutting a hollow soft rubber strip 10 , comprising: a workbench 100 , a conveying track 200 , a cutting mechanism 300 , and an integrated adsorption and dragging mechanism 400 .

[0040] like Figure 6 As shown, the conveying track 200 is fixed on the workbench 100, and a linear conveying groove 210 for accommodating the hollow soft rubber strip 10 is opened on the conveying track 200, and the two ends of the linear conveying groove 210 respectively form a feeding end 211 and a discharging end 212.

[0041] like Figure 4As shown, the cutting mechanism 300 is installed on the workbench 100. The cutting mechanism 300 includes a lifting drive module 310 and a cutting tool 320 connected to the lifting drive module 310. The cutting tool 320 is located above the conveying track 200. The lifting drive module 310 is used to drive the cutting tool 320 to rise and fall in the vertical direction to approach or move away from the conveying track 200, thereby cutting the hollow soft rubber strip 10 in the linear conveying trough 210. Figure 5 As shown, in this embodiment, the lifting drive module 310 is a cylinder drive structure. Furthermore, the cutting mechanism 300 also includes a support base 330, which is provided with a lifting guide rail 331. The cutting tool 320 is provided with a lifting slider that cooperates with the lifting guide rail 331, thereby improving the stability of the cutting tool 320 during the lifting process.

[0042] like Figure 4 As shown, the adsorption and dragging integrated mechanism 400 is provided on the workbench 100 and is located on the side of the discharge end 212 of the linear conveying trough 210. The adsorption and dragging integrated mechanism 400 is used to adsorb and drag one end of the hollow soft rubber strip 10 in the linear conveying trough 210.

[0043] like Figure 6 Specifically, the integrated suction and drag mechanism 400 includes a drag drive module 410 and a transfer platform 420 drivably connected to the drag drive module 410. The transfer platform 420 is provided with a suction assembly 430, which includes a suction panel 431 having a plurality of suction holes 432 arranged in a rectangular array. In this embodiment, the drag drive module 410 is driven by an electric cylinder.

[0044] The drag driving module 410 drives the transfer platform 420 to make the suction component 430 close to one end of the hollow soft rubber strip 10, and the suction hole 432 sucks air so that one end of the hollow soft rubber strip 10 is adsorbed on the suction panel 431, and the hollow cavity 11 of the hollow soft rubber strip 10 shrinks and becomes deflated.

[0045] like Figure 5 As shown, in the present invention, a material drop opening 110 is provided on the workbench 100 , and the material drop opening 110 is located at the discharge end 212 of the linear conveying trough 210 . Furthermore, a collection box 120 is provided at the material drop opening 110 .

[0046] Next, the working principle of the hollow soft rubber strip cutting device 20 is described (please refer to Figure 7 ):

[0047] Place a hollow soft rubber strip 10 to be cut into the linear conveying trough 210;

[0048] First, the suction and dragging integrated mechanism 400 is activated, and the drag driving module 410 drives the transfer platform 420 so that the suction component 430 is close to one end of the hollow soft rubber strip 10, and the suction hole 432 sucks air;

[0049] Under the suction force of the suction hole 432, one end of the hollow soft rubber strip 10 is adsorbed on the suction panel 431. At the same time, the high-speed airflow passes through the hollow cavity 11 of the hollow soft rubber strip 10. Based on the Bernoulli principle, the air flow rate in the hollow cavity 11 is accelerated, which reduces the air pressure in the hollow cavity 11. Therefore, the air outside the hollow soft rubber strip 10 will generate inward pressure on the hollow cavity 11, thereby causing the hollow cavity 11 of the hollow soft rubber strip 10 to shrink and become deflated (such as Figure 8 shown);

[0050] Since the hollow cavity 11 shrinks and becomes deflated, the entire hollow soft rubber strip 10 will temporarily become solid. When the hollow soft rubber strip 10 is cut, the end of the hollow soft rubber strip 10 will no longer undergo large elastic deformation, and the cut end will be more neat.

[0051] The lifting drive module 310 drives the cutting tool 320 to lift in the vertical direction to move closer to or away from the conveying track 200, thereby cutting the hollow soft rubber strip 10 in the linear conveying trough 210 to obtain small-section cutting products 30 (such as Figure 7 shown);

[0052] After cutting is completed, the lifting drive module 310 drives the cutting tool 320 to rise and reset;

[0053] Next, the dragging drive module 410 drives the transfer platform 420 to cause the suction assembly 430 to drag the small-sized cut product 30 in the linear conveying trough 210 (the suction holes 432 suck air to generate suction force), so that the small-sized cut product 30 is separated from the linear conveying trough 210.

[0054] When the small-cut product 30 reaches the designated position, the suction holes 432 stop sucking air. The small-cut product 30 is no longer affected by the suction force of the suction holes 432 and falls into the collection box 120 through the drop opening 110 under the action of gravity.

[0055] The drag driving module 410 continues to drive the transfer platform 420 to move the suction assembly 430 closer to one end of the hollow soft rubber strip 10. The suction hole 432 again sucks air, so that the one end of the hollow soft rubber strip 10 is adsorbed on the suction panel 431, and the hollow cavity 11 of the hollow soft rubber strip 10 shrinks again and becomes deflated.

[0056] The drag driving module 410 drags the hollow soft rubber strip 10 to the position to be cut, and the cutting mechanism 300 continues to cut the hollow soft rubber strip 10;

[0057] After cutting, the drag drive module 410 drives the transfer platform 420 again to cause the suction assembly 430 to drag the small-sized cut product 30 in the linear conveying trough 210 (the suction holes 432 suck air to generate suction force), so that the small-sized cut product 30 is separated from the linear conveying trough 210;

[0058] And so on.

[0059] The integrated adsorption and dragging mechanism 400 of the present invention solves the following technical problems and achieves corresponding technical effects:

[0060] Under the suction force of the suction hole 432, one end of the hollow soft rubber strip 10 is adsorbed on the suction panel 431, so that the hollow cavity 11 of the hollow soft rubber strip 10 shrinks and becomes deflated. Since the hollow cavity 11 shrinks and becomes deflated, the entire hollow soft rubber strip 10 will temporarily become solid. When the hollow soft rubber strip 10 is cut, the end of the hollow soft rubber strip 10 will no longer undergo large elastic deformation, and the cut end will be more neat. When the suction hole 432 stops sucking air, the hollow soft rubber strip 10 will recover its deformation and return to its original state, without affecting the quality of the hollow soft rubber strip 10.

[0061] Under the suction force of the suction hole 432, one end of the hollow soft rubber strip 10 is adsorbed on the suction panel 431, so that the drag driving module 410 can drag the hollow soft rubber strip 10 through the transfer platform 420. During the dragging process, although the hollow soft rubber strip 10 will produce friction with the linear conveying groove 210, the hollow soft rubber strip 10 is dragged and moved. Compared with pushing the hollow soft rubber strip 10, the extension line direction of the hollow soft rubber strip 10 will not bend and bounce, so that the hollow soft rubber strip 10 can be accurately conveyed to the cutting position;

[0062] It can be seen from this that the integrated adsorption and dragging mechanism 400 of the present invention is simple and efficient, and can simultaneously solve the technical problems of neat port cutting and accurate delivery.

[0063] The present invention also discloses a method for cutting hollow soft rubber strips, which is implemented by the above-mentioned hollow soft rubber strip cutting device and includes the following steps:

[0064] Step 1: Place the hollow soft rubber strip in the linear conveying trough;

[0065] Step 2: Drag the drive module to drive the transfer platform so that the suction component is close to one end of the hollow soft rubber strip, and the suction hole sucks air so that the end of the hollow soft rubber strip is adsorbed on the suction panel, and the hollow cavity of the hollow soft rubber strip shrinks and becomes deflated;

[0066] Step 3: The lifting drive module drives the cutting tool to move up and down in the vertical direction to move closer to or away from the conveying track, thereby cutting the hollow soft rubber strip in the linear conveying trough to obtain small cut products;

[0067] Step 4: The drag drive module drives the transfer platform to cause the suction component to drag the small-section cut products in the linear conveying trough, so that the small-section cut products are separated from the linear conveying trough;

[0068] Step 5: The air suction hole stops sucking air, and the small-section cut products fall off;

[0069] Step 6. Repeat steps 2 to 5.

[0070] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
