DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 10 As shown, the fully automatic egg cone paper machine of the present invention comprises a housing 1, a drop opening 13 is formed on the housing 1, a cup holder rod 11 is arranged around the drop opening 13, a cup tube 5 formed by stacking paper cups 51 is placed in the area surrounded by the cup holder rod 11, the paper cup 51 at the bottom of the cup tube 5 is inserted into the drop opening 13 and the cup mouth of the paper cup 51 is located above the drop opening 13, and a plurality of groups of drop openings 13 are arranged on the housing 1;

[0035] A cylinder 31 is installed on the top surface of the shell 1, a connecting frame 32 is installed on the cylinder 31, and a limit block 3 is installed on the connecting frame 32. The limit blocks 3 are symmetrically distributed on both sides of the cup tube 5. A sliding groove 38 is opened on the shell 1, and the connecting frame 32 is slidably installed in the sliding groove 38. The limit block 3 is located on the upper surface of the shell 1;

[0036] The stop block 3 contacts at least three paper cups 51 from bottom to top at the drop opening 13, and the side of the stop block 3 contacting the paper cup 51 is inclined, and the distance between the upper end of the stop block 3 and the drop opening 13 is smaller than the distance between the lower end of the stop block 3 and the drop opening 13;

[0037] A rotating shaft 21 is installed in the housing 1, and a cup dropping wheel 2 is installed on the rotating shaft 21. The cup dropping wheel 2 contacts the side of the paper cup 51 at the bottom of the cup tube 5. The cup dropping wheels 2 are symmetrically arranged on both sides of the cup tube 5. A blanking motor 22 is installed on the inner wall of the housing 1, and the blanking motor 22 drives the rotating shaft 21 and the cup dropping wheel 2 to rotate;

[0038] During operation, the controller controls the cylinder 31 to move, driving the limit block 3 in a direction away from the drop opening 13. Then, the cup tube 5 formed by stacking multiple paper cups 51 is placed in the area surrounded by the cup holder rod 11, so that the paper cup 51 at the bottom of the cup tube 5 enters the drop opening 13. The cup drop wheel 2 symmetrically arranged in the housing 1 will contact and support the paper cup 51 at the bottom of the cup tube 5 to prevent the cup tube 5 from falling due to insufficient support when placed. Then, the controller controls the cylinder 31 to reset, driving the limit block 3 to approach and squeeze the cup tube 5. Under the joint action of the limit block 3 and the cup drop wheel 2, the cup tube 5 is stably placed in the device.

[0039] At the same time, when placing paper cups 51 one by one, the controller controls the dropping motor 22 to drive the rotating shaft 1 21 and the cup dropping wheel 2 to rotate, so that the paper cup 51 at the bottom of the cup barrel 5 is driven by the cup dropping wheel 2 to move downward, until the cup mouth of the paper cup 51 at the bottom of the cup barrel 5 passes over the cup dropping wheel 2 downward, and the paper cup 51 continues to fall downward under the action of gravity, completing the dropping and placement of the paper cup 51. At the same time, when the cup dropping wheel 2 is in motion, the limit block 3 will keep squeezing the cup barrel 5, clamping and fixing the cup barrel 5, so that the cup dropping wheel 2 can smoothly drop the paper cup 51 at the bottom of the cup barrel 5.

[0040] At the same time, through the action of the cup dropping wheel 2, the cup dropping wheel 2 rotates a distance greater than or equal to the distance from the contact point of the cup dropping wheel 2 on the paper cup 51 to the cup mouth, thereby relatively accurately controlling the dropping of the paper cup 51 and regulating the number of paper cups 51 dropped per unit time, thereby meeting the production requirements;

[0041] At the same time, since the side of the limiting block 3 that contacts the paper cup 51 is inclined, when the limiting block 3 contacts and squeezes the cup tube 5, the upper end of the limiting block 3 squeezes the paper cup 51 in the cup tube 5, and the deformation amplitude of the paper cup 51 is relatively large, that is, the deformation amplitude of the several paper cups 51 below the cup tube 5 gradually increases from bottom to top, so that gaps appear or the gaps increase between the squeezed paper cups 51, and the upper end of the limiting block 3 has a relatively large clamping force on the cup tube 5, so that it is convenient for the cup dropping wheel 2 to drive the lowest paper cup 51 in the cup tube 5 to drop downward, and avoid the cup walls of the paper cups 51 being close to each other and difficult to separate under the action of air pressure, resulting in multiple paper cups 51 falling together;

[0042] At the same time, with the cooperation of the cup dropping wheel 2 and the limit block 3, it is possible to avoid the situation in the Chinese patent with publication number CN211003595U where the first clamping plate fails to clamp the upper end of the first ice cream paper cup 51, that is, the cup mouth of the second ice cream paper cup 51. For example, the ice cream cups are stacked too closely, so that the distance between the cup mouth of the first ice cream paper cup 51 and the cup mouth of the second ice cream paper cup 51 is relatively too small, so that the first clamping plate is clamped to the upper end of the second ice cream paper cup 51 or the first clamping plate is clamped to the cup mouths of the first and second ice cream cups at the same time, resulting in two ice cream paper cups 51 falling off or the ice cream paper cups 51 failing to fall off when the cups are dropped, thereby avoiding affecting the smooth progress of subsequent production.

[0043] As an embodiment of the present invention, a ventilation groove 33 is provided on the side of the stopper 3 contacting the paper cup 51, and the projection of the ventilation groove 33 on the vertical plane is a vertical line;

[0044] The ventilation groove 33 is provided with a blowing hole 35, the outlet direction of the blowing hole 35 is inclined downward, the limit block 3 is provided with a connecting groove 36, the connecting frame 32 is provided with a cavity, and the connecting frame 32 is provided with an air pipe 37, and the air pipe 37 is connected with the blowing hole 35 through the cavity and the connecting groove 36 in sequence;

[0045] A venting groove 33 is provided on the limit block 3, so that there is a relatively large and smooth airflow channel between the limit block 3 and the squeezed cup tube 5. Afterwards, when the paper cups 51 in the paper tube are squeezed by the limit block 3 and gaps appear between them, the external air source blows air out from the blowing hole 35 under the control of the controller, so as to promote the gaps between the paper cups 51 to be filled with air, and facilitate the expansion of the gaps between the paper cups 51 from small to large, so as to avoid the paper cups 51 from fitting and contacting each other. Under the action of air pressure, the paper cups 51 are closely attached to each other and are not easy to separate, which affects the separation and falling of the paper cups 51 or causes multiple paper cups 51 to fall at one time, affecting the smooth progress of production;

[0046] At the same time, since the outlet direction of the blowing hole 35 is inclined downward, the air blown out from the blowing hole 35 will flow downward along the ventilation groove 33, and then enter the gaps between the paper cups 51, so that the paper cups 51 are separated from each other, thereby promoting the increase of the gaps between the paper cups 51 and facilitating the subsequent dropping of the paper cups 51.

[0047] As an embodiment of the present invention, a silicone layer 34 is provided on the side of the limit block 3 contacting the paper cup 51, and the surface of the silicone layer 34 is frosted;

[0048] The lower end of the silica gel layer 34 does not contact the cup opening of the paper cup 51 at the lower end of the cup tube 5;

[0049] When the cup dropping wheel 2 rotates and drives the paper cup 51 at the bottom of the cup tube 5 to drop, the remaining stacked paper cups 51 in the cup tube 5 are clamped and fixed by the limiting block 3. Therefore, a silicone layer 34 is installed on the side of the limiting block 3 that contacts the paper cup 51, so that the silicone layer 34 and the paper cup 51 are in contact with each other. Under the condition of preventing the surface of the paper cup 51 from being damaged, the friction between the limiting block 3 and the cup tube 5 is increased as much as possible, thereby ensuring the stability of the position of the cup tube 5 in the device during the cup dropping process, preventing the cup tube 5 from sliding downward and affecting the dropping of the current paper cup 51 and subsequent paper cups 51 in the cup tube 5.

[0050] At the same time, because the lower end of the silicone layer 34 does not contact the cup mouth of the lowest paper cup 51 in the cup tube 5, the friction force of the limit block 3 on the lowest paper cup 51 in the cup tube 5 is different from that on the second paper cup 51 from the bottom to the top, thereby preventing the friction of the limit block 3 on the lowest paper cup 51 in the cup tube 5 from being too large, thereby preventing the paper cup 51 from falling downwards under the action of the cup dropping wheel 2 or the paper cup 51 from being damaged due to excessive force under the action of the cup dropping wheel 2.

[0051] As an embodiment of the present invention, a second rotating shaft 231 is installed on the inner wall of the housing 1, and a contact wheel 23 is installed on the second rotating shaft 231. The contact wheel 23 contacts the side of the paper cup 51 at the lower end of the cup tube 5. The contact wheels 23 are symmetrically arranged on both sides of the cup tube 5, and the contact wheels 23 are located above the blanking wheel.

[0052] Since the paper cups 51 have a small elasticity, when the paper cups 51 are stacked to form the cup tube 5, when the paper cups 51 are subjected to excessive pressure, the cup spacing h between two adjacent paper cups 51 in the cup tube 5 will change, causing the cup spacing h to deviate from the preset value range, resulting in the possibility that the cup wheel 2 pushes the two paper cups 51 downward continuously when the cups are dropped, affecting the cup dropping effect. At the same time, by providing the contact wheel 23 and locating the contact wheel 23 above the drop wheel, the cup drop wheel 2 drives the cup mouth of the bottom paper cup 51 downward to pass the position of the contact wheel 23, and the contact wheel 23 contacts the side of the second paper cup 51 from the bottom to the top, that is, the contact wheel 23 contacts and restricts the penultimate paper cup 51, preventing the penultimate paper cup 51 from moving downward with the action of the cup drop wheel 2, resulting in the dropping of multiple paper cups 51.

[0053] At the same time, since the diameter of the mouth of the paper cup 51 is the largest, and the spacing between the contact wheels 23 and the spacing between the cup-dropping wheels 2 are both smaller than the diameter of the mouth of the cup, the cup-dropping wheel 2 will drive the paper cup 51 to move downward through friction, and squeeze and deform the paper cup 51 during the cup-dropping process. Therefore, when the contact wheel 23 and the cup-dropping wheel 2 contact the lowest paper cup 51 at the same time, as the cup-dropping wheel 2 drives the paper cup 51 to move downward, the contact wheel 23 will rotate along with it. When the mouth of the lowest paper cup 51 passes through the contact wheel 23, the second-to-last paper cup 51 will be squeezed by the contact wheel 23. At this time, the second-to-last paper cup 51 is temporarily not driven by the cup-dropping wheel 2, so that the contact wheel 23 does not rotate, and the second-to-last paper cup 51 is limited to ensure that the second-to-last paper cup 51 is not driven by the friction of the lowest paper cup 51 and moves downward together.

[0054] As an embodiment of the present invention, the cup holder rod 11 is rotatably mounted on the housing 1, a toggle motor 121 is mounted on the top surface of the housing 1 to drive the cup holder rod 11 to rotate through a synchronous belt, and a toggle piece 12 is mounted on the cup holder rod 11;

[0055] The paddle plate 12 is spiral-shaped, and the paddle plate 12 is in contact with the paper cup 51 in the cup tube 5, and the lower end of the paddle plate 12 is located above the lowest paper cup 51 in the cup tube 5;

[0056] When the controller controls the air cylinder 31 to move and moves the limit block 3 away from the drop opening 13, the controller simultaneously controls the toggle motor 121 to move, so that the toggle motor 121 drives the cup holder rod 11 to rotate, and the toggle piece 12 to rotate, and to toggle and disturb the stacked cup tubes 5 upward, so that the stacked paper cups 51 in the cup tube 5 are loosened and relaxed, and the paper cups 51 in the middle and lower parts of the cup tube 5 are prevented from being squeezed and compacted and pressed together under the action of gravity, so that the paper cups 51 in the middle and lower parts of the cup tube 5 are not easily separated from each other, or multiple paper cups 51 are stuck together and separated at the same time, which affects the cup dropping effect of the paper cups 51.

[0057] As an embodiment of the present invention, the pitch of the toggle piece 12 gradually decreases from top to bottom, the toggle piece 12 is elastic, and the surface of the toggle piece 12 is frosted;

[0058] Because the paper cups 51 in the cup tube 5 are stacked on each other, the closer the paper cup 51 to the bottom of the cup tube 5 is to the greater the gravity of the paper cup 51 from above, so that the gravity of the paper cup 51 near the upper end of the paddle piece 12 is relatively small. In order to prevent the paper cup 51 from being subjected to too much gravity, the paddle piece 12 is elastically deformed and cannot paddle the paper cup 51. Therefore, when the paddle piece 12 rotates by the same angle, the paper cup 51 contacted by the upper end of the paddle piece 12 will be paddled first because the pitch of the paddle piece 12 gradually decreases from top to bottom. That is, the paddle piece 12 paddles the paper cup 51 by a relatively large distance, leaving space for the paper cup 51 below to move upward, ensuring that the paddle piece 12 can paddle the paper cup 51 in sequence from top to bottom, and the moving distance of the paper cup 51 gradually decreases, so that the paddled paper cups 51 all move upward by a certain distance, ensuring that the paper cups 51 are well loosened and relaxed.

[0059] As an embodiment of the present invention, the toggle piece 12 is sleeved and installed on the cup holder rod 11, and the cup holder rod 11 is provided with at least one group of toggle pieces 12;

[0060] When the number of paper cups 51 stacked at one time is relatively large and the height of the cup tube 5 is relatively large, the height of the cup holder rod 11 is also relatively long. At this time, multiple groups of shifting pieces 12 are provided on the cup holder rod 11, so that the paper cups 51 at different positions on the cup holder rod 11 can be shifted at the same time, so that the paper cups 51 can be loosened from each other, and the height of the cup tube 5 is prevented from being too high or the number of stacked paper cups 51 is too large, resulting in the shifting pieces 12 near the drop opening 13 being unable to shift the paper cups 51, and the paper cups 51 in the cup tube 5 cannot be loosened from each other, so that the paper cups 51 are pressed against each other, affecting the cup dropping effect or multiple paper cups 51 falling together, affecting the smooth progress of subsequent production.

[0061] As an embodiment of the present invention, a guide cylinder 4 is installed on the bottom surface of the housing 1, and the paper cup 51 at the bottom of the cup cylinder 5 is inserted into the guide cylinder 4. Elastic wires 41 are evenly arranged in the guide cylinder 4.

[0062] After the paper cup 51 falls, the paper cup 51 is guided by the guide cylinder 4 to ensure that the paper cup 51 falls smoothly to the designated position and avoids the paper cup 51 being deflected by the airflow during the falling process. At the same time, the elastic wire 41 arranged in the guide cylinder 4 keeps the paper cup 51 in the guide cylinder 4 in a centered and vertical state, further ensuring the effect of the paper cup 51 falling and ensuring that the paper cup 51 falls accurately to the designated position, so as to facilitate the smooth progress of subsequent production.

[0063] The specific workflow is as follows:

[0064] During operation, the controller controls the cylinder 31 to move, driving the limit block 3 in a direction away from the drop opening 13. Then, the cup tube 5 formed by stacking multiple paper cups 51 is placed in the area surrounded by the cup holder rod 11, so that the paper cup 51 at the bottom of the cup tube 5 enters the drop opening 13. The cup drop wheel 2 symmetrically arranged in the housing 1 will contact and support the paper cup 51 at the bottom of the cup tube 5. Then, the controller controls the cylinder 31 to reset, driving the limit block 3 to approach and squeeze the cup tube 5. Under the joint action of the limit block 3 and the cup drop wheel 2, the cup tube 5 is clamped.

[0065] At the same time, when placing paper cups 51 one by one, the controller controls the dropping motor 22 to drive the rotating shaft 1 21 and the cup dropping wheel 2 to rotate, so that the paper cup 51 at the bottom of the cup barrel 5 is driven by the cup dropping wheel 2 to move downward, until the cup mouth of the paper cup 51 at the bottom of the cup barrel 5 passes over the cup dropping wheel 2 downward, and the paper cup 51 continues to fall downward under the action of gravity, completing the dropping and placement of the paper cup 51. At the same time, when the cup dropping wheel 2 is in motion, the limit block 3 keeps clamping the cup barrel 5;

[0066] At the same time, through the action of the cup dropping wheel 2, the cup dropping wheel 2 rotates a distance greater than or equal to the distance from the contact point of the cup dropping wheel 2 on the paper cup 51 to the cup mouth, thereby relatively accurately controlling the drop of the paper cup 51 and regulating the number of paper cups 51 dropped per unit time;

[0067] At the same time, since the limiting block 3 is inclined to contact the side of the paper cup 51, the paper cups 51 below the cup tube 5 are deformed from bottom to top with a gradually increasing deformation amplitude, so that gaps appear or the gaps increase between the squeezed paper cups 51, and the upper end of the limiting block 3 has a relatively large clamping force on the cup tube 5, which facilitates the cup dropping wheel 2 to drive the paper cup 51 at the bottom of the cup tube 5 to drop downward;

[0068] When the paper cups 51 in the paper tube are squeezed by the stopper 3 and gaps appear between them, the external air source blows air out from the blowing holes 35 under the control of the controller, so as to fill the gaps between the paper cups 51 with air and expand the gaps between the paper cups 51 from small to large, thereby preventing the paper cups 51 from being pressed against each other and being difficult to separate under the action of air pressure.

[0069] At the same time, since the outlet direction of the blowing hole 35 is inclined downward, the air blown out from the blowing hole 35 will flow downward along the ventilation groove 33, and then enter the gaps between the paper cups 51, so that the paper cups 51 are separated from each other, and the gaps between the paper cups 51 are increased;

[0070] A silicone layer 34 is installed on the side of the stopper 3 contacting the paper cup 51, so that the silicone layer 34 and the paper cup 51 are in contact with each other, thereby increasing the friction between the stopper 3 and the cup tube 5;

[0071] At the same time, since the lower end of the silicone layer 34 does not contact the cup mouth of the lowest paper cup 51 in the cup tube 5, the friction force of the stopper 3 on the lowest paper cup 51 in the cup tube 5 and the second paper cup 51 from the bottom to the top is different, thereby preventing the friction of the stopper 3 on the lowest paper cup 51 in the cup tube 5 from being too large.

[0072] By providing the contact wheel 23 and making the contact wheel 23 located above the drop wheel, after the cup drop wheel 2 drives the bottommost paper cup 51 to pass through the position of the contact wheel 23, the contact wheel 23 will contact the side of the second paper cup 51 from bottom to top, that is, the contact wheel 23 contacts and restricts the penultimate paper cup 51, preventing the penultimate paper cup 51 from moving downward with the action of the cup drop wheel 2, resulting in the drop of multiple paper cups 51;

[0073] At the same time, when the contact wheel 23 and the cup drop wheel 2 contact the bottom paper cup 51 at the same time, as the cup drop wheel 2 drives the paper cup 51 to move downward, the contact wheel 23 will rotate accordingly. When the mouth of the bottom paper cup 51 passes through the contact wheel 23, the second-to-last paper cup 51 will be squeezed by the contact wheel 23. At this time, the second-to-last paper cup 51 is temporarily not driven by the cup drop wheel 2, so that the contact wheel 23 does not rotate, and the second-to-last paper cup 51 is limited, ensuring that the second-to-last paper cup 51 will not be driven by the friction force of the bottom paper cup 51 and move downward together;

[0074] When the controller controls the air cylinder 31 to move so that the limit block 3 is away from the drop opening 13, the controller simultaneously controls the toggle motor 121 to move, so that the toggle motor 121 drives the cup holder rod 11 to rotate, so that the toggle piece 12 rotates, and the stacked cup tubes 5 are toggled and disturbed upward, so that the paper cups 51 stacked on each other in the cup tubes 5 are loosened and relaxed from each other;

[0075] Since the paper cups 51 in the cup tube 5 are stacked on each other, the paper cups 51 closer to the bottom of the cup tube 5 are subjected to greater gravity from the top of the paper cups 51, so that the paper cups 51 near the upper end of the toggle piece 12 are subjected to relatively smaller gravity from the top. In order to prevent the paper cups 51 from being subjected to too much gravity, the toggle piece 12 is elastically deformed and cannot toggle the paper cups 51. Therefore, when the toggle piece 12 rotates at the same angle, since the pitch of the toggle piece 12 gradually decreases from top to bottom, the paper cups 51 contacted by the upper end of the toggle piece 12 will be toggled first, that is, the toggle distance of the upper end of the toggle piece 12 to the paper cups 51 is relatively large, leaving space for the paper cups 51 below to move upward, ensuring that the toggle piece 12 can toggle the paper cups 51 from top to bottom in sequence, and the moving distance of the paper cups 51 gradually decreases, so that the toggle paper cups 51 are all moved upward by one end distance, ensuring a good effect of mutually loosening and relaxing the paper cups 51.

[0076] A plurality of groups of shifting pieces 12 are provided on the cup holder rod 11 to shift paper cups 51 at different positions on the cup holder rod 11 at the same time, so that the paper cups 51 are mutually loosened, and the height of the cup tube 5 is prevented from being too high or the number of stacked paper cups 51 is too large, so that the shifting pieces 12 near the drop opening 13 cannot shift the paper cups 51, and the paper cups 51 in the cup tube 5 cannot be mutually loosened;

[0077] After the paper cup 51 falls, the paper cup 51 is guided by the guide cylinder 4 to ensure that the paper cup 51 falls smoothly to the designated position and avoids the paper cup 51 being deflected by the airflow during the falling process. At the same time, the elastic wire 41 arranged in the guide cylinder 4 keeps the paper cup 51 in the guide cylinder 4 in a centered and vertical state, further ensuring the effect of the paper cup 51 falling and ensuring that the paper cup 51 falls accurately to the designated position, so as to facilitate the smooth progress of subsequent production.
