Detailed implementation manners

[0049] The following further elaborates the present invention in detail in conjunction with the accompanying drawings and specific embodiments.

[0050] As Figures 1-11As shown in the figure, an embodiment of the present invention provides a cover roll paper gluing and forming device for a conical plastic cylinder, which includes a clamping and pressing mechanism 1, a supporting and forming female die 2, a paper sheet positioning mechanism 3, a left paper roll pushing mechanism 4, a right paper roll pushing mechanism 5, and a glue coating mechanism 6 arranged in sequence on a frame; wherein, the clamping and pressing mechanism 1 is used to clamp and fix the conical plastic cylinder 9 and then move down to the supporting and forming female die 2; the supporting and forming female die 2 is used to place the paper sheet, and at the same time, when the clamping and pressing mechanism 1 moves down, it can drive the paper sheet to fit with the forming groove 23 on the supporting and forming female die 2 to generate curling; the paper sheet positioning mechanism 3 is arranged on the forming groove 23 of the supporting and forming female die 2 and is used to adsorb and fix the bottom of the paper sheet; the left paper roll pushing mechanism 4 and the right paper roll pushing mechanism 5 are respectively arranged on the left and right sides of the frame to curl and press the paper sheets on the left and right sides of the conical plastic cylinder 9; the glue coating mechanism 6 is used to perform a glue coating action on the paper sheets curled and pressed at the top of the conical plastic cylinder 9 to cooperate with the right paper roll pushing mechanism 5 to perform a crimping and gluing action.

[0051] The clamping and pressing mechanism 1 is composed of a clamping fixture 11 and a displacement module 12; wherein, the clamping fixture 11 includes: a T-shaped plate 111, an inner support seat 112, and a claw cylinder 113; the inner support seat 112 and the claw cylinder 113 are detachably installed on the T-shaped plate 111, and the upper and lower claw ends of the claw cylinder 113 are located in the receiving groove 1123 on the inner support seat 112 and can open and close up and down in the receiving groove 1123. At the same time, the claw end of the claw cylinder 113 also includes an anti-slip silicone block 114 arranged thereon, which can increase the frictional resistance between it and the inner wall of the plastic cylinder; when the above clamping fixture 11 is used, first, the plastic cylinder body can be manually sleeved onto the inner support seat 112, and then the two claws of the claw cylinder 113 are controlled to open outwards to further clamp and fix the inner wall of the plastic cylinder body, thereby improving the fixing effect on the plastic cylinder body and avoiding displacement or loosening of the plastic cylinder body, resulting in errors in subsequent paper roll actions.

[0052] The displacement module 12 includes: a vertical rail 121, a downward pressing air cylinder 122, and a hydraulic buffer 123; the number of the vertically arranged rails 121 is two, which are arranged on the left and right sides of the frame and are slidably connected to the rear side wall of the T-shaped plate 111. The cylinder part of the downward pressing air cylinder 122 is installed on the frame, and the piston rod part is connected to the upper end of the T-shaped plate 111. The hydraulic buffers 123 are respectively arranged on the left and right sides of the downward pressing air cylinder 122 and are used to generate buffer protection when touching the downward moving T-shaped plate 111. When the above displacement module 12 is used, the downward pressing air cylinder 122 can be controlled to move up and down, so as to drive the T-shaped plate 111 and the fixed plastic cylinder body to move up and down under the guidance of the vertical rail 121. At the same time, by using the elastic buffer force of the hydraulic buffer 123, a protection buffer effect is generated on the downward moving T-shaped plate 111, that is, in order to reduce the impact force when the plastic cylinder body is in contact with the forming groove 23 on the support forming die 2, so as to improve the anti-collision protection of the forming die.

[0053] The inner support seat 112 includes: a support cushion plate 1121, a support cone seat 1122, a receiving groove 1123, and a T-shaped connection block 1124; the front side wall of the support cushion plate 1121 is integrally formed with a support cone seat 1122. The diameter of the support cone seat 1122 can be set to match the inner diameter of the plastic cylinder body, and the support cone seat 1122 is made of hard anti-slip rubber material. A through receiving groove 1123 is vertically opened on the support cone seat 1122, so that the support cone seat 1122 is divided into arc-shaped support plates on the left and right sides. The protruding part of the T-shaped connection block 1124 is inserted into the front side of the receiving groove 1123, and the T-shaped connection block 1124 and the arc-shaped support plates on the left and right sides are locked and connected by locking screws. By using the connection of the T-shaped connection block 1124, it is further possible to avoid the phenomenon that the arc-shaped support plates on the left and right sides will approach each other and deform due to the opening of the receiving groove 1123, that is, by using the structure of the T-shaped connection block 1124, the structural stability between the two arc-shaped support plates and the T-shaped connection block 1124 can be strengthened, so as to reduce the degree of deformation caused by external extrusion. When the above inner support seat 112 is used, by inserting the support cone seat 1122 into the plastic cylinder body, the purpose of internal support of the plastic cylinder body can be achieved, avoiding the purpose of supporting and protecting the plastic cylinder body during the subsequent pressing operations of the paper roll pressing plate one 45, the paper roll pressing plate two 46, the paper roll pressing plate three 55, the paper roll pressing plate four 56, and the pressing plate 575, and preventing the plastic cylinder body from being squeezed and deformed and damaged. At the same time, by using the diameter of the support cone seat 1122 that can be set to match the inner diameter of the plastic cylinder body, the plastic cylinder body can be initially positioned, and combined with the clamping of the above clamping jaw cylinder 113, the effect of secondary fixing of the plastic cylinder body is achieved.

When the above-mentioned paper sheet positioning mechanism 3 is in use, the placed cover paper sheet 10 can be vacuum adsorbed and fixed by using the vacuum suction cup 36, so as to avoid the displacement of the cover paper sheet 10 during downward movement. When the displacement module 12 presses down, it drives the plastic cylinder to contact the top of the cover paper sheet 10, and then synchronously drives the cover paper sheet 10 and the vacuum suction cup 36 and the reset rod 33 on the paper sheet positioning mechanism 3 to move downward together, that is, the vacuum suction cup 36 and the reset rod 33 are synchronously pressed downward until the vacuum suction cup 36 moves into the avoidance groove 24. While realizing the adsorption and fixation of the paper sheet, it does not affect the downward paper rolling action of the paper sheet.
