Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, in particular to a rubber hose cutting equipment. Background Art

The guide rails 108 can support and guide the rack I 106 and rack II 107 to ensure that the rack I 106 and rack II 107 can be stably lifted and lowered. The top front side of the base 1 is connected with a connecting sleeve 11, and the bottom of the collection frame 102 is connected with a telescopic tube 12 for discharging waste chips, and the telescopic tube 12 passes through the connecting sleeve 11.

[0033] The upper part of the frame 2 is rotatably connected with a support frame 13 that can swing up and down. The support frame 13 is located between the two conveyors 3 and is used to support the rubber hose. The support frame 13 includes an L-shaped connecting plate 131, a U-shaped supporting plate 132, an L-shaped connecting rod 133 and a roller 134; the upper part of the inner wall on both the front and rear sides of the frame 2 is rotatably connected with an L-shaped connecting plate 131, a U-shaped supporting plate 132 for supporting the rubber hose is connected between the two L-shaped connecting plates 131, and four rollers 134 are rotatably connected in the U-shaped supporting plate 132 at even intervals from left to right. The rollers 134 are used to support and guide the rubber hose, and the lower parts of the two L-shaped connecting plates 131 are connected with an L-shaped connecting rod 133. The upper part of the frame 2 is provided with a pushing assembly for driving the support frame 13 to swing up and down. The pushing assembly includes two front and rear L-shaped push rods Ⅰ141 rotatably connected to the upper part of the frame 2. The two L-shaped push rods Ⅰ141 are located between the two mounting seats 81. The tops of the two L-shaped push rods Ⅰ141 are connected with slotted blocks 142. The two sliding rods Ⅰ82 corresponding to the front and rear of the right side are both slidably sleeved with L-shaped push rods Ⅱ143. The two L-shaped push rods Ⅱ143 are respectively located on the outside of the two slotted V-shaped clamping blocks Ⅰ83 corresponding to the front and rear of the right side. The two L-shaped push rods Ⅱ143 are respectively in the grooves of the two slotted blocks 142. The sliding rod Ⅰ82 on the right side is sleeved with an elastic member 144. The two ends of the elastic member 144 are respectively connected to the L-shaped push rod Ⅱ143 and the mounting seat 81. The elastic member 144 is a spring. The lower sides of the two L-shaped connecting plates 131 and the lower sides of the two L-shaped push rods Ⅰ141 are connected with ball joints 146, the L-shaped connecting rod 133 is connected to the ball of the upper ball joint 146, the L-shaped push rod Ⅰ141 is connected to the ball of the upper ball joint 146, and a push plate 145 is connected between the left and right ball joints 146, and the push plate 145 is connected to the ball seat on the ball joint 146. The ball joint 146 is a prior art and will not be described in detail here.

[0034] Place the rubber hose on the conveyor 3, control the conveyor 3 to work and convey the rubber hose to the right. When the rubber hose is conveyed to the right to a suitable length, control the conveyor 3 to stop working. Then control the telescopic rods of the electric push rods 88 on both sides to extend synchronously, so as to push the slotted V-shaped clamping blocks II85 on both sides to approach each other to clamp and limit the rubber hose. When the slotted V-shaped clamping blocks II85 on both sides approach each other, the guide rod 84 drives the slotted V-shaped clamping blocks I83 on both sides to approach each other to clamp and limit the rubber hose. Then control the telescopic rods of the two double-headed cylinders 89 on both sides to extend synchronously, so as to push the movable blocks 87 on both sides to drive the upper parts away from each other, and the slotted V-shaped clamping blocks II85 on both sides move away from each other. Since the slotted V-shaped clamping blocks II85 on both sides clamp the rubber hose at this time, the slotted V-shaped clamping blocks II85 on both sides move away from each other to straighten and tighten the rubber hose, and avoid the loosening phenomenon in the cutting area of ​​the rubber hose, so as to improve the flatness of the end face of the cut of the rubber hose. Since the rubber hose is also clamped and limited by the slotted V-shaped clamp block Ⅰ83, the slotted V-shaped clamp blocks Ⅰ83 on the left and right sides move away from each other, which will only straighten and tighten the rubber hose without pulling the rubber hose to move, thereby ensuring that the cutting length of the rubber hose is accurate and the cutting accuracy is guaranteed. The friction between the rubber hose and the slotted V-shaped clamp block Ⅰ83 can be reduced by the ball 9, thereby preventing the rubber hose from being damaged by friction with the slotted V-shaped clamp block Ⅰ83 when it is straightened and tightened.

[0035] After the rubber hose is straightened and tightened by the slotted V-shaped clamp block II 85, the rodless cylinder 5 is controlled to work to drive the lifting plate I 6 to drive the circular saw 7 to move downward and upward reciprocatingly. The circular saw 7 moves downward to cut the rubber hose. The circular saw 7 is a prior art and will not be described in detail here. Since the rubber hose is clamped and limited by the slotted V-shaped clamp block I 83 and the slotted V-shaped clamp block II 85, and is straightened and tightened by the V-shaped clamp block II, the deformation of the rubber hose during the cutting process can be effectively avoided, and the stability and accuracy of the rubber hose during the cutting process can be ensured, thereby improving the cutting accuracy and flatness, ensuring the flatness of the end face of the rubber hose, and then improving the subsequent connection quality of the rubber hose with other components, ensuring better sealing and functionality. When the circular saw 7 moves up and disengages from the rubber hose to complete a cutting operation, the telescopic rods of the front and rear electric push rods 88 are first controlled to shorten synchronously to pull the slotted V-shaped clamps II 85 on the front and rear sides away from each other to loosen the rubber hose. When the slotted V-shaped clamps II 85 on the front and rear sides move away from each other, the slotted V-shaped clamps I 83 on the front and rear sides are driven to move away from each other through the guide rod 84 to loosen the rubber hose. Then, the telescopic rods of the front and rear two double-headed cylinders 89 are controlled to shorten synchronously to pull the movable blocks 87 on the left and right sides to drive the upper parts thereof to move closer to each other, and the slotted V-shaped clamps II 85 on the left and right sides move closer to each other accordingly.

[0036] When the lifting plate Ⅰ6 drives the circular saw 7 to move downward to cut the rubber hose, it drives the rack Ⅱ107 to move downward, and the rack Ⅱ107 moves downward to push the small gear 104 to rotate with the rotating shaft 103, so that the large gear 105 rotates, and the large gear 105 rotates to push the rack Ⅰ106 to move the lifting plate Ⅱ101 upward, so that the collection frame 102 can move upward to approach the saw blade on the circular saw 7 and cover the lower part of the saw blade of the circular saw 7. Since the middle part of the collection frame 102 is concave downward, the collection frame 102 will not squeeze the rubber hose after moving upward, so that the collection frame 102 can be kept at the lower side of the rubber hose and cover the lower part of the saw blade of the circular saw 7, and then the waste generated during cutting can be blocked and collected by the collection frame 102 to reduce the risk of waste splashing everywhere, thereby keeping the working environment clean. When the lifting plate Ⅰ6 drives the circular saw 7 to move upward, it also drives the rack Ⅱ107 to move upward. The upward movement of the rack Ⅱ107 drives the small gear 104 to reverse the rotating shaft 103, so that the large gear 105 reverses and drives the rack Ⅰ106 to move downward. The downward movement of the rack Ⅰ106 drives the lifting plate Ⅱ101 to move downward with the collection frame 102. The telescopic tube 12 is connected to an external suction device, and the waste in the collection frame 102 can be extracted outward through the telescopic tube 12, so as to realize the recycling of rubber crumbs, reduce the waste of materials, and do not need to manually clean the waste in the collection frame 102, which can save labor.

[0037] When the two corresponding slotted V-shaped clamping blocks I83 on the right front and back are in an open state, the slotted V-shaped clamping blocks I83 squeeze the L-shaped push rod II 143, and the elastic member 144 is in a compressed state. When the two corresponding slotted V-shaped clamping blocks I83 on the right front and back are close to clamp the rubber hose, the slotted V-shaped clamping blocks I83 are separated from the L-shaped push rod II 143. Under the reset action of the elastic member 144, the L-shaped push rod II 143 is pushed to move in the direction close to the U-shaped support plate 132. The L-shaped push rod II 143 moves in the direction close to the U-shaped support plate 132, pushing the slotted block 142 to drive the L-shaped The push rod Ⅰ141 rotates, and the L-shaped push rod Ⅰ141 rotates to push the push plate 145 to move rightward through the ball joint 146 thereon. The push plate 145 moves rightward and pushes the L-shaped connecting rod 133 to swing to the lower right through the ball joint 146 thereon. The L-shaped connecting rod 133 swings to the lower right and drives the U-shaped supporting plate 132 to swing to the lower right to a vertical state through the L-shaped connecting plate 131, so that the entire supporting frame 13 swings to the lower right to a vertical state to avoid the circular saw 7 and the collection frame 102, avoid hindering the subsequent lifting of the circular saw 7 and the collection frame 102, and ensure smooth cutting work. When a cutting operation is completed, the two corresponding slotted V-shaped clamping blocks Ⅰ83 on the right side move away from each other and open, and the slotted V-shaped clamping block Ⅰ83 pushes the L-shaped push rod Ⅱ143 to move and reset, and the elastic member 144 is compressed, and the L-shaped push rod Ⅱ143 moves and resets, pushing the slotted block 142 to drive the L-shaped push rod Ⅰ141 to reverse, and the L-shaped push rod Ⅰ141 reverses and pulls the push plate 145 to move to the left through the ball joint 146 thereon, and the push plate 145 moves to the left and pulls the L-shaped connecting rod 133 to swing to the upper left through the ball joint 146 thereon, and the L-shaped connecting rod 113 swings to the upper left. The U-shaped support plate 132 swings upward to the left through the L-shaped connecting plate 131, thereby the entire support rack 13 swings upward to the left to the horizontal state, so as to support the cut rubber hose, and prevent the ends of the two rubber hoses that are close to each other from falling and deforming, thereby preventing the ends of the two rubber hoses that are close to each other from falling to the lower side of the conveyor 3 and affecting the subsequent transmission of the rubber hose, thereby ensuring the stability of the rubber hose after cutting, and ensuring that the rubber hose can be continuously and effectively transmitted by the conveyor 3. The rubber hose can be supported and guided by the roller 134 to reduce the friction between the rubber hose and the U-shaped support plate 132, so that the rubber hose can move more smoothly and avoid the rubber hose and the U-shaped support plate 132 from being damaged by friction.

[0038] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
