Description

Technical Field

[0001] The present invention belongs to the technical field of paper cup production, and particularly relates to a paper cup bundling device and method for paper cup production. Background Art

[0002] During the production process of paper cups, after the paper cups are formed, they are stacked together, and then the paper cups are bundled and packaged. Currently, there is a bundling and packaging device. For example, a paper cup bundling device for paper cup production with the patent publication number CN222158040U. Its main technical means is to set an automatic counting device on the first workbench. This device can automatically count the number of paper cups. The setting of the first clamping block can move the counted paper cups forward a certain distance through the telescopic rod to separate them from the uncounted paper cups, saving a large amount of time for manual counting. After analysis by the applicant, the disadvantages of this technical solution are as follows: Since the paper cups are stacked together before bundling and packaging, there may be a situation where two adjacent paper cups are closely attached, making it difficult to separate the two paper cups. If the above solution is used to separate the paper cups, when the two closely attached paper cups are exactly at the separation position, it may occur that the two paper cups cannot be separated, and one or more uncounted paper cups may be carried at the rear end of the counted paper cups, resulting in a situation where there are more paper cups in the package after this bundling and packaging of the paper cups. And the size of the film packaging is fixed. If there are more paper cups, it may cause the film to not be properly sealed. Summary of the Invention

[0003] The purpose of the present invention is to provide a paper cup bundling device and method for paper cup production in view of the deficiencies of the prior art, so as to solve the technical problem that the paper cups in a single package may be more during the bundling and packaging of paper cups, resulting in the film not being properly sealed.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A paper cup bundling device for paper cup production includes a telescopic member, a first clamping member, a second clamping member, a front clamping plate, a rear clamping plate, an automatic counting device, a first conveyor belt, a film guiding plate, a second conveyor belt, an ultrasonic sealing machine, and a film cutting knife. The device further includes:

[0006] A separation assembly, the separation assembly includes a driving member, the driving member is installed inside one of the rear clamping plates, and a separation block is installed at the output end of the driving member. The cross-sectional thickness of the separation block increases gradually.

[0007] A stop bar, stop bars are arranged inside both of the front clamping plates, and the stop bars block at the curled edge of the cup mouth of the paper cup.

[0008] Preferably, as the above technical solution, the side of the separation block close to the driving member is a flat surface, and the opposite side is a spiral surface. A guide groove is provided on the spiral surface, and a stabilizing component is connected in the guide groove. The stabilizing component includes a flat box, a push rod is connected to the flat box, the push rod is slidably installed in the guide groove, and one side of the flat box and the flat surface on the separation block respectively abut against the rolled edges of the cup mouths of two stacked paper cups.

[0009] Preferably, as the above technical solution, one end of the push rod penetrates through the flat box and is provided with a guiding member. Two rotating rods are symmetrically and rotatably installed on both sides of the flat box. One end of the rotating rod abuts against the guiding surface of the guiding member, and the other end extends out of the flat box. An elastic member three is connected between the rotating rod and the top end of the inner cavity of the flat box. An elastic member two is connected between the guiding member and the inner wall of the flat box. A guide bar is provided in the guide groove. An inclined surface is provided on one side of the bottom end of the guide bar close to the push rod, and an inclined surface is also provided at this end of the push rod. That is, when the push rod moves onto the guide bar, the push rod moves towards the flat box.

[0010] Preferably, as the above technical solution, a rotating component is installed inside the two rear clamping plates. The rotating component includes two rotating bars. The rotating bars are slidably installed inside the rear clamping plates. When the two rear clamping plates clamp the stacked paper cups, the rotating bars abut against the back of the paper cups. A driving bar and a connecting bar are respectively provided on the two rotating bars. The driving bar is connected to the rotating bar on the rear clamping plate where the driving member is installed, and the connecting bar is connected to the rotating bar on the other rear clamping plate. When the two rear clamping plates are combined, the end of the driving bar abuts against the end of the connecting bar. A tooth groove is provided on the driving bar, and a gear is installed at the output end of the driving member. The gear meshes with the tooth groove on the driving bar. A telescopic groove is provided inside the rear clamping plate, and an elastic member one is installed in the telescopic groove. The elastic member one is elastically connected to the rotating bar.

[0011] Preferably, as the above technical solution, the two front clamping plates after combination and the two rear clamping plates after combination are coaxial. The stacked paper cups are not coaxial with the two front clamping plates after combination and the two rear clamping plates after combination. The axis of the stacked paper cups is below the axis of the two front clamping plates after combination and the two rear clamping plates after combination. When the two rear clamping plates are combined, the two rotating bars approach the stacked paper cups and lift the stacked paper cups, so that the several paper cups to be separated are coaxial with the two front clamping plates after combination and the two rear clamping plates after combination.

[0012] Preferably, as the above technical solution, after the two rear clamping plates are combined, the two rotating bars, the driving bar and the connecting bar form an incomplete circle, and the two rear clamping plates after combination, the two rotating bars and the several paper cups to be separated are coaxial.

[0013] As an optimization of the above technical solution, a plurality of first spray holes are formed on the plane of the separation block close to the driving member. The separation block is connected to an external air supply unit. A plurality of second spray holes are formed on one side of the rotating bar close to the driving member. The rotating bar is connected to an external air supply unit.

[0014] A bundling method for a paper cup bundling device for paper cup production. The method is applied to the paper cup bundling device for paper cup production as described above. The method includes the following steps:

[0015] Step S1: Place the stacked paper cups on the first conveyor belt and transport them to the automatic counting device through the first conveyor belt. Start counting the paper cups through the automatic counting device.

[0016] Step S2: After counting is completed, the first clamping member and the second clamping member respectively control the two front clamping plates and the two rear clamping plates to clamp the paper cups. The two front clamping plates clamp the front ends of the uncounted paper cups, and the two rear clamping plates clamp the rear ends of the counted paper cups. When the two rear clamping plates are combined, the two rotating bars lift the last counted paper cup at the rear end, and several paper cups connected together at the front and rear ends are also lifted. When the two front clamping plates are combined, the two blocking bars abut against the rolled edge of the cup mouth of the uncounted paper cup at the front end, so that the uncounted paper cups will not move forward continuously.

[0017] Step S3: When the two rear clamping plates are combined, the separation block is located between the two paper cups to be separated. At this time, start the driving member to make the separation block rotate. When the separation block rotates, since the cross-sectional thickness of the separation block becomes larger and larger, the two paper cups are gradually separated.

[0018] Step S4: While the driving member is started, the gear drives the driving bar to move, the driving bar drives the rotating bar connected thereto to rotate, the driving bar pushes the connecting bar, so that the connecting bar drives the rotating bar connected thereto to rotate. By rotating the two rotating bars, the paper cups to be separated can be rotated, thereby promoting the separation of the paper cups.

[0019] Step S5: After the paper cups are separated, the telescopic member pushes the second clamping member so that the two rear clamping plates drive the counted paper cups to separate from the uncounted paper cups. The counted paper cups are transported to the film guiding plate through the first conveyor belt and enter the film. The film is sealed by an ultrasonic sealing machine, and the cutting knife cuts the film so that the ends of the film are adhered together, thereby completing the bundling of the paper cups.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. In the present invention, by rotating the separation block, the thickness between the rolled edges of the cup mouths of the two paper cups where the separation block is located becomes larger and larger, so that the separation block squeezes one of the paper cups, and then the two paper cups are gradually separated. In this way, it is possible to prevent one or more uncounted paper cups from being carried at the rear end of the counted paper cups, avoid the situation where there are too many paper cups entering the film, and avoid the film being unable to be normally sealed.

[0022] 2. In the present invention, while the separation block separates the two paper cups, the two rotating bars rotate to drive the paper cups to be separated, thereby promoting the separation of the paper cups and improving the separation effect. At the same time, it also prevents the cup rim curling from being deformed due to the stress exerted on the cup rim curling when the separation block separates the paper cups that are closely attached.

[0023] 3. In the present invention, when the two front clamping plates and the two rear clamping plates merge, the two rotating bars on the two rear clamping plates will lift the paper cup to be separated, along with several other paper cups at the front and rear ends, and away from the conveyor belt 1. This can prevent the paper cups from being affected by the friction of the conveyor belt 1 during separation and rotation, ensuring smooth rotation and separation of the paper cups, thereby further improving the separation effect.

[0024] 4. In the present invention, high-pressure air is injected into the gap between the two paper cups. The high-pressure air can push the paper cups, thereby promoting the separation of the paper cups. At the same time, the injected high-pressure air can increase the air pressure in the gap. When the internal air pressure approaches or exceeds the external atmospheric pressure, the pressure difference between the two paper cups disappears, and the external atmospheric pressure no longer compresses the paper cups, greatly reducing the separation resistance. In addition, after entering the gap, the high-pressure air can push the two layers of paper cups apart, directly destroying the sealing state, and the high-speed airflow may form a temporary "air cushion" on the contact surface, reducing the friction coefficient, making the paper cups easier to rotate and separate, thereby improving the separation effect.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 8 shown, a paper cup bundling device for paper cup production includes a telescopic member 1, a clamping member one 2, a clamping member two 3, a front splint 4, a rear splint 5, an automatic counting device 9, a conveyor belt one 10, a film guiding plate 11, a conveyor belt two 12, an ultrasonic sealer 13 and a film cutting knife 14. The device further includes:

[0037] A separation assembly 6, the separation assembly 6 includes a driving member 61, the driving member 61 is installed inside one of the rear splints 5, and a separation block 62 is installed at the output end of the driving member 61, and the cross-sectional thickness of the separation block 62 increases gradually;

[0038] Stop bars 41, stop bars 41 are provided on the inner sides of both front splints 4, and the stop bars 41 block at the curled edges of the cup mouths of the paper cups.

[0039] In actual application of this embodiment, when the two rear splints 5 clamp the counted paper cups, the separation block 62 is located between the two paper cups to be separated, that is, between the curled edges of the cup mouths at two positions. At this time, the driving member 61 is started to make the separation block 62 rotate, so that the thickness of the separation block 62 between the curled edges of the cup mouths of the two paper cups becomes larger and larger, thereby making the separation block 62 squeeze one of the paper cups, and then gradually separating the two paper cups. In this way, it is possible to prevent one or more uncounted paper cups from being carried at the rear end of the counted paper cups, avoid the situation where there are too many paper cups entering the film, and avoid the film from being unable to be normally sealed.

[0040] Furthermore, one side of the separating block 62 close to the driving member 61 is a flat surface, and the opposite side is a spiral surface. A guiding groove 621 is formed on the spiral surface, and a stabilizing assembly 8 is connected in the guiding groove 621. The stabilizing assembly 8 includes a flat box 81. A push rod 82 is connected to the flat box 81. The push rod 82 is slidably installed in the guiding groove 621. One side of the flat box 81 and the flat surface on the separating block 62 respectively abut against the rolled edges of the cup mouths of two stacked paper cups.

[0041] One end of the push rod 82 penetrates through the flat box 81 and is provided with a guiding member 83. Rotating rods 84 are symmetrically and rotatably installed on both sides of the flat box 81. One end of the rotating rod 84 abuts against the guiding surface of the guiding member 83, and the other end extends out of the flat box 81. An elastic member three 86 is connected between the rotating rod 84 and the top end of the inner cavity of the flat box 81. An elastic member two 85 is connected between the guiding member 83 and the inner wall of the flat box 81. A guiding bar 622 is arranged in the guiding groove 621. An inclined surface is provided on one side of the bottom end of the guiding bar 622 close to the push rod 82. An inclined surface is also provided at this end of the push rod 82. That is, when the push rod 82 moves onto the guiding bar 622, the push rod 82 moves towards the flat box 81.

[0042] In actual application of this embodiment, since one side of the separating block 62 is a spiral surface, when the spiral surface of the separating block 62 contacts the rolled edge of the cup mouth of the paper cup, the spiral surface will apply an inclined stress to the rolled edge of the cup mouth, and the stress is concentrated. This may cause the rolled edge of the cup mouth to deform, thereby reducing the quality of the paper cup. Using the flat box 81 to contact the rolled edge of the cup mouth instead of the spiral surface can make the stress received at the rolled edge of the cup mouth uniform, thereby effectively avoiding the deformation of the rolled edge of the cup mouth and ensuring the quality of the paper cup.

[0043] Since the flat box 81 is connected to the separating block 62 through the push rod 82, when the push rod 82 moves along the guiding groove 621, the flat box 81 may move along with the push rod 82, resulting in the flat box 81 being unable to always abut against the rolled edge of the cup mouth. When the separating block 62 rotates, the push rod 82 will move onto the guiding bar 622. At this time, the push rod 82 will move towards the flat box 81. The push rod 82 drives the guiding member 83 to move, so that the guiding member 83 squeezes the two rotating rods 84 on both sides, causing the rotating rods 84 to rotate and abut against the surface of the paper cup. In this way, both sides of the flat box 81 are restricted by the two rotating rods 84, effectively avoiding the flat box 81 moving along with the push rod 82 and ensuring that the flat box 81 always abuts against the rolled edge of the cup mouth during the separation process, thereby ensuring the separation effect.

[0044] Such as Figures 3 - 6As shown in the figure, a rotating assembly 7 is installed inside the two rear clamping plates 5. The rotating assembly 7 includes two rotating bars 72. The rotating bars 72 are slidably installed inside the rear clamping plates 5. When the two rear clamping plates 5 clamp the stacked paper cups, the rotating bars 72 abut against the back of the paper cups. A driving bar 73 and a connecting bar 74 are respectively arranged on the two rotating bars 72. The driving bar 73 is connected to the rotating bar 72 on the rear clamping plate 5 where the driving member 61 is installed, and the connecting bar 74 is connected to the rotating bar 72 on the other rear clamping plate 5. When the two rear clamping plates 5 are combined, the end of the driving bar 73 abuts against the end of the connecting bar 74. A tooth groove is formed on the driving bar 73, and a gear 71 is installed at the output end of the driving member 61. The gear 71 meshes with the tooth groove on the driving bar 73. A telescopic groove is formed inside the rear clamping plate 5, and a first elastic member 75 is installed in the telescopic groove. The first elastic member 75 is elastically connected to the rotating bar 72.

[0045] In practical application of this embodiment, when the separating block 62 separates two paper cups, the driving member 61 drives the gear 71 to rotate. Since the end of the driving bar 73 abuts against the end of the connecting bar 74 when the two rear clamping plates 5 are combined, the gear 71 drives the driving bar 73 to move towards the connecting bar 74. The driving bar 73 drives the connected rotating bar 72 to rotate along the inner wall of the rear clamping plate 5. The connecting bar 74 drives the connected rotating bar 72 to rotate along the inner wall of the other rear clamping plate 5 under the push of the driving bar 73. The rotation directions of the two rotating bars 72 are the same, so that the two rotating bars 72 drive the paper cups to be separated to rotate, thereby promoting the separation of the paper cups, improving the separation effect, and at the same time avoiding the large stress on the rolled edge of the cup mouth when the paper cups are tightly attached and the separating block 62 separates, resulting in the deformation of the rolled edge of the cup mouth; after the counted paper cups are separated, the two rear clamping plates 5 are separated, and at the same time the driving member 61 rotates in reverse. With the cooperation of the first elastic member 75, the separating block 62, the driving bar 73, the connecting bar 74 and the two rotating bars 72 are reset;

[0046] The inner shape of the rotating bar 72 fits the surface shape of the paper cup. To ensure that the rotating bar 72 drives the paper cup to rotate, a component for increasing friction can be provided on the inner side of the rotating bar 72, which can be a rubber layer, so as to ensure that the rotating bar 72 can drive the paper cup to rotate and improve the separation effect.

[0047] Furthermore, after combination, the two front clamping plates 4 and the two combined rear clamping plates 5 are coaxial. The stacked paper cups are not coaxial with the two combined front clamping plates 4 and the two combined rear clamping plates 5. The axis of the stacked paper cups is below the axis of the two combined front clamping plates 4 and the two combined rear clamping plates 5. When the two rear clamping plates 5 are combined, the two rotating bars 72 approach the stacked paper cups and lift the stacked paper cups, so that the several paper cups to be separated are coaxial with the two combined front clamping plates 4 and the two combined rear clamping plates 5.

[0048] When the two rear clamping plates 5 are combined, the two rotating bars 72, the driving bar 73 and the connecting bar 74 form an incomplete circle. The combined two rear clamping plates 5, the two rotating bars 72 and the paper cups to be separated are coaxial.

[0049] In actual application of this embodiment, when the two front clamping plates 4 and the two rear clamping plates 5 are merged, the two rotating bars 72 on the two rear clamping plates 5 will lift the paper cup to be separated together with the several paper cups in front and rear ends thereof and away from the conveyor belt 10. This can prevent the paper cups from being affected by the friction of the conveyor belt 10 during separation and rotation, ensure that the paper cups rotate and separate smoothly, and thus further improve the separation effect.

[0050] like Figure 6 As shown, the separation block 62 is provided with a plurality of spray holes 623 on the plane close to the driving member 61, and the separation block 62 is connected to the external air supply unit. The rotating bar 72 is provided with a plurality of spray holes 721 on the side close to the driving member 61, and the rotating bar 72 is connected to the external air supply unit.

[0051] In actual use of this embodiment, if the two paper cups are closely fitted together, the separation block 62 and the rotating assembly 7 may be unable to separate the two cups, and the cups may be damaged. As the separation block 62 rotates, high-pressure air can be injected into the gap between the two cups through the first nozzle 623. At the same time, the rotating bar 72 rotates and injects high-pressure air into the gap between the two cups through the second nozzle 721. The high-pressure air can push the cups, thereby promoting the separation of the cups. At the same time, the injected high-pressure air can increase the air pressure in the gap. When the internal air pressure approaches or exceeds the external atmospheric pressure, the pressure difference between the two cups disappears, the external atmospheric pressure no longer compresses the cups, and the separation resistance is greatly reduced. In addition, after entering the gap, the high-pressure air can push the two layers of paper cups apart, directly destroying the sealed state. The high-speed airflow can form a temporary "air cushion" on the contact surface, reducing the friction coefficient, making the cups easier to rotate and separate, thereby improving the separation effect.

[0052] The injected high-pressure air can be hot air or cold air, that is, the air temperatures injected by nozzle 1 623 and nozzle 2 721 are different. For example, nozzle 1 623 injects hot air, while nozzle 2 721 injects cold air. The hot air can cause the surface of the paper cup to expand slightly, while the cold air can cause the surface of the lower paper cup to contract slightly. Due to the different positions of the injected air, the two paper cups will deform unevenly. This uneven deformation may destroy the sealing between the paper cups, allowing external air to penetrate the gap and balance the internal and external air pressure, thereby further reducing the separation resistance and further improving the separation effect.

[0053] A paper cup bundling method for a paper cup production device is provided. The method is applied to the paper cup bundling device for paper cup production as described above, and the method comprises the following steps:

[0054] Step S1: Place the stacked paper cups on conveyor belt 10, and convey them to the automatic counting device 9 through conveyor belt 10. Start counting the paper cups through the automatic counting device 9;

[0055] Step S2: After counting is completed, clamping member 1 and clamping member 2 respectively control two front clamping plates 4 and two rear clamping plates 5 to clamp the paper cups. Two front clamping plates 4 clamp the front end of the uncounted paper cups, and two rear clamping plates 5 clamp the rear end of the counted paper cups. When the two rear clamping plates 5 are combined, two rotating bars 72 lift the last counted paper cup at the rear end, and several paper cups connected together at the front and rear ends are also lifted. When the two front clamping plates 4 are combined, two stop bars 41 abut against the rolled edge of the cup mouth of the uncounted paper cup at the front end, so that the uncounted paper cups will not move forward continuously;

[0056] Step S3: When the two rear clamping plates 5 are combined, the separating block 62 is located between the two paper cups to be separated. At this time, start the driving member 61 to make the separating block 62 rotate. When the separating block 62 rotates, since the cross-sectional thickness of the separating block 62 becomes larger and larger, the two paper cups are gradually separated;

[0057] Step S4: At the same time as the driving member 61 is started, the gear 71 drives the driving bar 73 to move, the driving bar 73 drives the rotating bar 72 connected thereto to rotate, the driving bar 73 pushes the connecting bar 74, so that the connecting bar 74 drives the rotating bar 72 connected thereto to rotate. By rotating the two rotating bars 72, the paper cups to be separated can be rotated, thereby promoting the separation of the paper cups;

[0058] Step S5: After the paper cups are separated, the telescopic member 1 pushes the clamping member 2 so that the two rear clamping plates 5 drive the counted paper cups to separate from the uncounted paper cups. The counted paper cups are conveyed to the film guiding plate 11 through conveyor belt 10 and enter the film. The film is sealed by the ultrasonic sealer 13, and the film cutting knife 14 cuts the film so that the ends of the film are adhered together, thereby completing the bundling of the paper cups.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.

8. A bundling method for a paper cup bundling device for paper cup production, the method is applied to the paper cup bundling device for paper cup production according to any one of the above claims 1-7, and the method includes the following steps: Step S1: Place the stacked paper cups on the first conveyor belt (10), and transmit them to the automatic counting device (9) through the first conveyor belt (10), and start counting the paper cups through the automatic counting device (9); Step S2: After counting is completed, the first clamping member (2) and the second clamping member (3) respectively control the two front clamping plates (4) and the two rear clamping plates (5) to clamp the paper cups. The two front clamping plates (4) clamp the front ends of the uncounted paper cups, and the two rear clamping plates (5) clamp the rear ends of the counted paper cups; when the two rear clamping plates (5) are merged, the two rotating bars (72) lift the last counted paper cup at the rear end, and several paper cups connected together at the front and rear ends are also lifted. When the two front clamping plates (4) are merged, the two blocking bars (41) abut against the cup mouth curling of the uncounted paper cup at the front end, so that the uncounted paper cups will not move forward continuously; Step S3: When the two rear clamping plates (5) are merged, the separating block (62) is located between the two paper cups to be separated. At this time, the driving member (61) is started to rotate the separating block (62). When the separating block (62) rotates, since the cross-sectional thickness of the separating block (62) becomes larger and larger, the two paper cups are gradually separated; Step S4: At the same time as the driving member (61) is started, the gear (71) drives the driving bar (73) to move, the driving bar (73) drives the connected rotating bar (72) to rotate, the driving bar (73) pushes the connecting bar (74), so that the connecting bar (74) drives the connected rotating bar (72) to rotate. The paper cups to be separated can be rotated by the rotation of the two rotating bars (72), thereby promoting the separation of the paper cups; Step S5: After the paper cups are separated, the telescopic member (1) pushes the second clamping member (3) so that the two rear clamping plates (5) drive the counted paper cups to separate from the uncounted paper cups. The counted paper cups are transported to the film guiding plate (11) through the first conveyor belt (10) and enter the film. The film is sealed by the ultrasonic sealing machine (13), and the film cutting knife (14) cuts the film so that the ends of the film stick together, thus completing the bundling of the paper cups.
