Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic belt conveying, in particular to a disposable plastic cup blowing plastic belt conveying device. BACKGROUND

[0002] Disposable plastic cups are widely used in catering, retail and other scenarios due to their convenience, and their processing efficiency and product quality directly affect the production capacity and market competitiveness of production enterprises. At present, the processing flow of disposable plastic cups mainly includes the following steps: the material belt is input from one side of the blowing machine, moves upwardly and obliquely to the top of the blowing machine after passing between the upper and lower molds of the blowing machine, and is finally wound by the winding machine; and the disposable plastic cups formed by the blowing machine are blown onto the hopper.

[0003] However, the existing processing flow has the following defects in actual application:

[0004] 1. The material belt for blowing is prone to adhere to dust and other impurities during transfer and conveying, and there is a lack of cleaning process for the material belt in the current processing system. When the material belt with impurities enters the blowing link, the impurities are easily embedded in the cup body forming structure, resulting in surface defects, insufficient structural strength and other problems of the disposable plastic cup, which seriously affects the product forming quality.

[0005] 2. The formed cup bodies need to be stacked manually, which not only takes a long time, but also causes microbial contamination when the workers contact the cup bodies one by one. Although some existing technologies design multiple sets of ring-shaped conveying belts to receive the blown cup bodies to achieve rapid stacking, the cup bodies often fall in a disordered state on the ring-shaped conveying belts, and the workers need to clean and adjust frequently, which is tedious. In addition, the material belt input system needs to be configured on one side of the blowing machine, and the ring-shaped conveying belt needs to be set on the other side, which significantly increases the length of the entire processing line and expands the occupied area, which is not conducive to the space optimization of the production workshop.

[0069] 4. The cup body 900 can be output in rows by using the ring-shaped conveying belt 510, and combined with the brush cleaning roller group 320 and the guide plate 540, so that the cup body 900 is adjusted to an inclined state, so that the cup body 900 is intermittently jacked up by the upper jacking and stacking assembly 600, and the cup body 900 is stacked one by one without manual stacking, and the worker only needs to adjust the box, thereby effectively improving the processing efficiency of the cup body 900.

At the same time, the electrostatic elimination group 330 can also serve as the installation basis of the vertical poking assembly 700.

[0086] Only relying on the lower brush roller 323 can make more unqualified cup bodies 900 stay at the feeding area 511. In order to improve the dimensional adjustment of the cup body 900 and speed up the output speed of the cup body 900, the vertical poking assembly 700 in the embodiment comprises a poking piece 710, a horizontal linkage rod 740, a vertical linkage rod 750 and a bottom plate 720. The side wall of the conveying base 500 is provided with the bottom plate 720. The surface of the bottom plate 720 is fixedly provided with a first supporting rod 721. The surface of the bottom plate 720 is rotatably provided with a second supporting rod 722. The top end of the second supporting rod 722 is fixedly provided with a first rotating plate 730. The top surface of the first rotating plate 730 is provided with a first driving column 731. The outer end of the lower brush roller 323 is provided with a bevel gear rod 324. The outer wall of the second supporting rod 722 is provided with a matching bevel gear 732 engaged with the bevel gear rod 324. The middle part of the horizontal linkage rod 740 is rotatably installed at the top end of the first supporting rod 721. The two ends of the horizontal linkage rod 740 are provided with a first sliding groove 741 and a second sliding groove 742.

The bottom surface of the assembly plate 333 is rotatably provided with a plurality of poking pieces 710. The rack 751 is engagedly connected with the plurality of poking pieces 710.

[0087] In the above scheme:

[0088] 1. The vertical poking assembly 700 converts the rotation of the first rotating plate 730 into the longitudinal sliding of the vertical linkage rod 750 through the linkage structure of the horizontal linkage rod 740 and the vertical linkage rod 750. The rack 751 of the vertical linkage rod 750 drives the synchronous action of the plurality of poking pieces 710, so as to realize the uniform poking of the cup body 900 in the feeding area 511 and avoid the problem of local adjustment out of place.

[0089] 2. The driving force of the horizontal linkage rod 740 comes from the bevel gear rod 324 of the lower brush roller 323, so as to ensure that the poking action matches the conveying speed of the cup body 900, avoid adjustment lag or excessive poking, improve the posture adjustment precision, and also avoid the need to separately set a driving structure.

[0090] In the embodiment, the poking piece 710 comprises a rotating column 711, a fixed plate 712 and vertical brush hairs 713. A plurality of groups of rotating columns 711 are longitudinally and spaced apart. The plurality of groups of rotating columns 711 are rotatably installed at the bottom surface of the assembly plate 333. The outer wall of each group of rotating columns 711 is provided with a first gear 714. The rack 751 is engagedly connected with the plurality of first gears 714. The bottom end of each group of rotating columns 711 is vertically provided with a group of fixed plates 712. The bottom surface of the fixed plate 712 is uniformly embedded with vertical brush hairs 713.

[0091] In the above scheme: the fixed plate 712 of the toggle piece 710 is embedded at the bottom of the vertical brush 713 (flexible material), when the cup body 900 is toggled, the vertical brush 713 is in flexible contact with the cup body 900, avoiding surface damage caused by rigid scraping, and ensuring the appearance quality of the cup body 900. The rotating column 711 drives the fixed plate 712 and the vertical brush 713 to do circular motion, and the vertical brush 713 can agitate the cup body 900 from multiple directions, adjust the cup body 900 in all directions, and ensure that the cup body 900 is adjusted to be close to the vertical state, and the posture qualified rate is improved.

[0092] In order to make the material guide plate 540 smoothly guide the cup body 900, in the embodiment, the material guide plate 540 includes a horizontal support plate 541, the bottom surface of the horizontal support plate 541 is provided with a fixed rod 542, the input end of the horizontal support plate 541 is provided with an arc-shaped guide plate 543, the surface of the horizontal support plate 541 is symmetrically provided with a side constraint plate 544, and the height of the horizontal support plate 541 is lower than the top height of the annular conveying belt 510.

[0093] In the above scheme: the arc-shaped guide plate 543 of the material guide plate 540 can abut against the bottom end of the vertical cup body 900, guide the cup body 900 to be lifted and gradually tilted, and avoid tilting caused by direct collision; the horizontal support plate 541 supports the bottom of the tilted cup body 900, ensuring smooth conversion. The side constraint plate 544 of the material guide plate 540 is symmetrically distributed on both sides of the horizontal support plate 541, and the tilted cup body 900 is horizontally constrained to avoid cup body 900 deviation, ensuring that the cup body 900 accurately enters the stacking constraint channel 530 (cooperating with the horizontal material belt of the first guide conveying assembly 200), providing accurate positioning for subsequent automatic stacking.

[0094] In order to realize the stable stacking of the cup body 900, in the embodiment, the upper stacking assembly 600 includes a driving long shaft 610, a horizontal guide rail 670, and an abutting convex plate 651, the driving long shaft 610 is rotatably installed in the conveying base 500, the outer wall of the driving long shaft 610 is provided with a plurality of second gears 620, the top of the horizontal guide rail 670 is slidably installed with a vertical rod 660, the top outer wall of the vertical rod 660 is vertically sleeved with a sliding sleeve 650, the top of the sliding sleeve 650 is provided with the abutting convex plate 651, the side wall of the sliding sleeve 650 is provided with a connecting column 642, the connecting column 642 is fixedly arranged on the side wall of the second rotating plate 640, the second rotating plate 640 is rotatably installed on the inner side of the supporting plate 630, the rotating shaft end of the second rotating plate 640 is provided with a third gear 641, the third gear 641 is in meshing connection with the second gear 620, and the supporting plate 630 is fixedly installed inside the conveying base 500, and is used to provide support.

[0095] In the above scheme:

[0096] 1. The drive shaft 610 of the upper stacking assembly 600 drives the second gear 620 to rotate, and drives the second rotating plate 640 to rotate through the third gear 641. The second rotating plate 640 drives the sliding sleeve 650 to slide vertically along the vertical rod 660 through the connecting column 642, so that the contacting convex plate 651 reciprocates to extend outward from the annular conveyor belt 510, intermittently lifting the cup body 900 (temporarily holding the cup body 900). The subsequent cup body 900 can be accurately fitted onto the tail end of the previous temporary cup body 900, realizing automatic stacking without manual intervention.

[0097] 2. The vertical sliding range (top height) and lateral movement (resistance force) of the contact plate 651 are precisely controlled by gear transmission to avoid excessive force from damaging the cup body 900. At the same time, the rotation frequency of the drive shaft 610 is matched with the conveying speed of the ring conveyor belt 510 to ensure that the stacking rhythm is coordinated with the conveying rhythm of the cup body 900, thereby improving the compactness and efficiency of stacking.

[0098] Working principle and usage process of this invention:

[0099] S1, Belt 110 Conveyor:

[0100] The feeding roller 100 operates intermittently and actively, releasing the material belt 110. When the material belt 110 passes between the upper brush roller 322 and the lower brush roller 323, the upper brush roller 322 and the lower brush roller 323, which rotate in opposite directions, work together to clean the residual impurities on both sides of the material belt 110. The brushed-off impurities will move towards the fifth guide roller 312. The dust extraction fan 314 generates negative pressure at the dust extraction port 313, causing the impurities to be output through the interior of the fifth guide roller 312.

[0101] Then the material strip 110 will pass through two sets of plasma fan boxes 332. The plasma fan box 332 can output plasma air to eliminate the static electricity on both sides of the material strip 110. Then the material strip 110 is output to the blow molding machine 800. Multiple circular pieces are cut downwards on the material strip 110. The circular pieces are heated and blown by the upper and lower molds in the blow molding machine 800 to produce disposable plastic cups. The cut waste strip is wound up on the take-up roller 430.

[0102] When the upper and lower molds of the blow molding machine 800 are opened, the discharge fan 810 blows out high-pressure gas, causing the cup body 900 to be blown out and then discharged through the discharge ramp 820.

[0103] S2, Cup body 900 output:

[0104] The falling cup 900 falls irregularly on the annular conveying belt 510. When the cup 900 passes each group of poking members 710, the lower brush roller 323 drives the bevel gear 324 to rotate when rotating, the bevel gear 324 drives the matching bevel gear 732 to rotate, and then drives the second supporting rod 722 and the first rotating plate 730 to rotate. The first rotating plate 730 drives the first driving column 731 to rotate, the first driving column 731 moves in the second sliding groove 742, and drives the horizontal linkage rod 740 to rotate around the hinge point of the first supporting rod 721. The first sliding groove 741 of the horizontal linkage rod 740 abuts against the second driving column 752 to move longitudinally, the second driving column 752 drives the vertical linkage rod 750 to move longitudinally, the vertical linkage rod 750 drives each group of first gears 714 to rotate through the rack 751, the first gears 714 drive the rotating column 711 to rotate, and then drive the fixed plate 712 and the vertical brush 713 at the bottom to move in a ring shape. The vertical brush 713 can stir the cup 900, so that the cup 900 horizontally and vertically lapped on the annular conveying belt 510 is adjusted in posture, so that most of the cups 900 are vertically clamped between the two annular conveying belts 510;

[0105] After one-time posture adjustment, the cup 900 passes the bottom of the lower brush roller 323, and the lower brush roller 323 vertically adjusts the posture of the cup 900, so that only the cup 900 clamped between the two annular conveying belts 510 is output;

[0106] After two-time posture adjustment, the cup 900 continues to be output along the annular conveying belt 510. The bottom end of the vertically arranged cup 900 is first abutted against the arc-shaped guide plate 543, so that the cup 900 is lifted to an inclined state close to horizontal, the opening of the cup 900 faces upward, and the cup 900 is stacked on the horizontal material belt. The inclined cup 900 is continuously conveyed by the annular conveying belt 510, a horizontal material belt located above forms a stacking constraint channel 530 with the annular conveying belt 510, and then the cup 900 enters the stacking constraint channel 530, and the side constraint plate 544 guides and constrains the cup 900;

[0107] The driving long shaft 610 drives the second gear 620 to rotate, and then drives the third gear to rotate, the third gear 641 drives the second rotating plate 640 and the connecting column 642 to rotate, the connecting column 642 drives the sliding sleeve 650 to move, the sliding sleeve 650 vertically slides along the vertical rod 660, and also drives the vertical rod 660 to move horizontally along the horizontal guide rail 670, so that the abutting convex plate 651 reciprocatingly extends outward to the annular conveying belt 510. The abutting convex plate 651 abuts against the cup 900, so that the cup 900 is lifted and temporarily retained, and the subsequent newly input cup 900 is sleeved on the tail end of the cup 900 which is temporarily retained by being lifted. The horizontal material belt can vertically stop the stacked cup 900, so as to avoid the cup 900 from being lifted excessively and separated;

[0108] The first driving rod 211 and the second driving rod 241 are started in time, when started, the cup body 900 has been stacked for a certain number, and the subsequent cup body 900 needs to be stopped from entering the stacking constraint channel 530; the second driving rod 241 drives the fourth guide roller 240 to descend, the first driving rod 211 drives the first guide roller 210 to descend, the fourth guide roller 240 drives the bottom material belt 110 to approach the ring-shaped conveying belt 510, and is placed in front of the entrance end of the stacking constraint channel 530, so that the fourth guide roller 240 and the material belt 110 on the bottom surface thereof can stop the input cup body 900 in an inclined state, at this time, the worker can quickly take down each stacked cup body 900 to the operation plate 520, so as to further regularize the packaging.
