[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to embodiments.

[0033] Example:

[0034] Please see Figures 1-8 The transfer device for the paper cup and paper bowl production line with heat insulation sleeve includes a base, on which a first conveyor frame 1 and a second conveyor frame 2 are symmetrically arranged. The first conveyor frame 1 and the second conveyor frame 2 are both driven by existing technology to control the conveying, which will not be described in detail here. The conveying process of the first conveyor frame 1 and the second conveyor frame 2 is controllable.

[0035] The accompanying drawings of this invention only illustrate the transfer process of paper cups with heat-insulating sleeves, but the transfer device of this invention is also applicable to the transfer of paper bowls with heat-insulating sleeves; multiple sets of inner cups 3 and multiple sets of outer cups 4 are respectively transferred on the first transfer frame 1 and the second transfer frame 2. The inner cups 3 are used to hold liquids, and the outer cups 4 are used for heat insulation.

[0036] The first conveyor frame 1 and the second conveyor frame 2 are each provided with two sets of support rods 5 on opposite sides. The two sets of support rods 5 are provided with crossbeams 6. The crossbeams 6 are "L" shaped and are divided into a horizontal part and a vertical part. The bottom side of the vertical part is connected to the top surface of the support rod 5.

[0037] In addition, it also includes a flipping component 7, which has two sets and is respectively located below the two sets of crossbeams 6, for flipping the inner cup 3 and the outer cup 4 and bonding them into an assembly 13.

[0038] Specifically, the flipping assembly 7 includes a first telescopic rod 71, the upper end of which is fixedly connected to the bottom surface of the vertical part. One end of the output shaft of the first telescopic rod 71 is connected to a horizontal rod 72. Two sets of torsion springs 73 are symmetrically fixedly connected to both ends of the horizontal rod 72. The other end of the torsion springs 73 is located inside the flipping plate 74. The two sets of torsion springs 73 are mirror images of each other, so that the flipping plate 74 can be flipped in the same direction.

[0039] The flip plate 74 has a movable groove 741 on the side near the support rod 5. The movable groove 741 prevents the flip plate 74 from hitting the first telescopic rod 71 when it flips. A transverse groove 742 is provided in the movable groove 741. The other ends of the two sets of torsion springs 73 are respectively connected to the two inner walls of the transverse groove 742. The cross rod 72 is rotatably engaged with the transverse groove 742, and the two ends of the torsion springs 73 are respectively fixedly connected to one end of the cross rod 72 and the inner wall of the transverse groove 742. Thus, after the flip plate 74 flips at a certain angle, it can return to the initial position under the action of the torsion springs 73.

[0040] Furthermore, a baffle 75 is provided on the side of the first telescopic rod 71 away from the support rod 5. The baffle 75 is vertically installed on the bottom surface of the crossbeam 6 and is located on the bottom surface of the horizontal part for flipping the flip plate 74.

[0041] The rotary adhesive spraying assembly 9 is connected to multiple sets of second telescopic rods 8 located below one set of flipping assemblies 7, which are positioned above the inner cup 3. The rotary adhesive spraying assembly 9 is used to spray adhesive onto the outer surface of the inner cup 3.

[0042] Below the rotating adhesive spraying assembly 9 is a first electrostatic adsorbent 10 for adsorbing the inner cup 3; multiple sets of third telescopic rods 11 are provided, all located below another set of flipping assemblies 7, and each set of third telescopic rods 11 is equipped with a second electrostatic adsorbent 12 for adsorbing the outer cup 4. Pressure switches (not shown in the figure) are provided below both the first electrostatic adsorbent 10 and the second electrostatic adsorbent 12 to control the operation of the first telescopic rod 71.

[0043] The rotary adhesive spraying assembly 9 includes a rotating rod 91, which is connected to the second telescopic rod 8 via a bearing 81. By setting the bearing 81, the rotating rod 91 can rotate without affecting the operation of the output shaft of the second telescopic rod 8.

[0044] The outer surface of the rotating rod 91 has a first vertical groove 911, a spiral groove 912, and a second vertical groove 913. The two ends of the spiral groove 912 are connected to the first vertical groove 911 and the second vertical groove 913, respectively. One end of the second vertical groove 913 is connected to a third vertical groove 914 via a first inclined groove, and one end of the third vertical groove 914 is connected to the first vertical groove 911 via a second inclined groove. A first one-way plate 9131 is provided at the end of the second vertical groove 913, and a second one-way plate 9141 is provided at the end of the third vertical groove 914 near the second inclined groove. The spiral groove 912 facilitates the reverse rotation of the rotating rod 91 under the influence of other components.

[0045] The rotating rod 91 has a guide rod 92 that slides on its surface. The guide rod 92 is fixedly connected to the bottom surface of the flip plate 74 via a connecting rod 93. The guide rod 92 slides in conjunction with the first vertical groove 911, the spiral groove 912, and the second vertical groove 913.

[0046] A cam 94 is sleeved on the end of the guide rod 92 near the bearing 81. It is worth noting that the cam 94 is a structure composed of four protrusions and four flat sections, which can better play the role of repeatedly compressing and pulling the piston rod 96.

[0047] The cam 94 is pressed and fitted with a compression plate 95. A piston rod 96 is provided on one side of the compression plate 95. The piston rod 96 slides inside the piston cylinder 97. A spring 961 is sleeved on the piston rod 96. The two ends of the spring 961 are fixedly connected to the inner wall of the compression plate 95 and the top surface of the piston cylinder 97, respectively.

[0048] Initially, the highest point of one of the protrusions of cam 94 contacts compression plate 95, and is in a state of compressing compression plate 95. At this time, spring 961 is in a compressed state, and at the same time, the second telescopic rod 8 and the third telescopic rod 11 are activated. When the output shaft of the second telescopic rod 8 extends, the guide rod 92 slides in the first vertical groove 911. When it reaches the middle of the first vertical groove 911, it attracts the inner cup 3. The first electrostatic adsorbent 10 and the second electrostatic adsorbent 12 attract the inner cup 3 and the outer cup 4 respectively, and at the same time, the pressure switch is triggered, causing... The output shaft of the first telescopic rod 71 retracts, causing the rotating glue spraying assembly 9 to move upward as a whole. At this time, the baffle 75 contacts and presses against the flipping plate 74, causing it to flip in reverse. The guide rod 92 is still in the first vertical groove 911, and the output shaft of the second telescopic rod 8 continues to extend. During the flipping process, the guide rod 92 gradually moves from the first vertical groove 911 into the spiral groove 912. At this time, the cam 94 rotates synchronously. Under the rebound force of the spring 961, the compression plate 95 is always in contact with the cam 94, and the glue extraction and spraying begin.

[0049] The outer surface of the piston cylinder 97 is connected to a nozzle 98 via a connecting pipe. The outer surface of the piston cylinder 97 is also connected to an external glue bucket via a pipe (not shown in the figure). A one-way valve is provided at the connection between the pipe and the piston cylinder 97, allowing only external glue to flow into the piston cylinder 97. When the rotating rod 91 rotates and the flat part contacts the compression plate 95, it is in the glue extraction state. Under the rebound force of the spring 961, the compression plate 95 drives the piston rod 96 to slide inside the piston cylinder 97, extracting external glue to the bottom of the piston cylinder 97. When the protrusion contacts the compression plate 95, it is in the glue spraying state.

[0050] One end of the piston cylinder 97 is connected to the fixed plate 99, which is vertically positioned on one side of the bottom surface of the flip plate 74. The compression plate 95 has an "L" shaped structure, with one end of the compression plate 95 slidingly engaged with the fixed plate 99 to support the compression plate 95.

[0051] When the guide rod 92 slides to the end of the spiral groove 912 and is about to enter the second vertical groove 913, the flip plate 74 is in a vertical state, the glue spraying on the outer surface of the inner cup 3 is completed, and the output shafts of the second telescopic rod 8 and the third telescopic rod 11 continue to extend. When they reach the end of the second vertical groove 913, the output shafts of the second telescopic rod 8 and the third telescopic rod 11 stop working, and the inner cup 3 and the outer cup 4 are bonded together to form the assembly 13. At this time, the first electrostatic adsorbent 10 is released, and the assembly 13 is adsorbed by the second electrostatic adsorbent 12. Then, the output shafts of the second telescopic rod 8 and the third telescopic rod 11 are allowed to extend. As the shaft retracts, the first telescopic rod 71 slowly extends and gradually returns to its initial state. At this time, the two sets of flip plates 74 gradually return to their initial horizontal state under the restoring force of the torsion spring 73. The end of the second vertical groove 913 is provided with a first one-way plate 9131, which only allows the guide rod 92 to enter the third vertical groove 914 in one direction through the inclined groove one, and slowly enter the bottom of the third vertical groove 914. The bottom of the third vertical groove 914 is provided with a second one-way plate 9141. Through the second one-way plate 9141, only the guide rod 92 is allowed to enter the first vertical groove 911 in one direction through the inclined groove two, so as not to affect subsequent use.

[0052] The third telescopic rod 11 on the other side is simultaneously in a vertical state, so that the output shaft of the third telescopic rod 11 extends out, so that the assembly 13 adsorbed by the second electrostatic adsorber 12 is placed on the second conveyor 2 and conveyed to the next process. After that, the output shaft of the third telescopic rod 11 returns to its initial height, so as not to affect the subsequent work.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
