Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging equipment, in particular to a paper cup packaging machine for Ganoderma tea drinks and a packaging process. BACKGROUND

[0002] The paper cup packaging machine for Ganoderma tea drinks is a special equipment for realizing powder quantitative filling and paper cup sealing packaging in the field of Ganoderma tea drink food and health products. In the packaging process, the Ganoderma tea drink is first accurately injected into the paper cup according to the set dose, then the composite barrier film of the preset specification is covered on the top opening of the paper cup, and finally the top film is heat sealed with the paper cup opening by pressing the hot head and applying a specific temperature and pressure.

[0003] In the paper cup packaging operation of Ganoderma tea drinks, the barrier film is directly placed on the cup opening, which causes the barrier film to be in a relaxed state when being conveyed to the packaging station. When the hot head presses the top film downward according to the set program, the relaxed top film cannot form a stable plane support, and is prone to local wrinkling and stacking under the pressure of the hot head. Specifically, irregular wrinkles appear in the contact area between the top film and the paper cup opening, and some areas even form a multi-layer film stacking state due to wrinkling and stacking. Such top film wrinkling problem will directly cause a series of hot sealing defects, such as virtual sealing, film material damage, and air bubbles between the heat sealing layers. Based on this, the present application provides a paper cup packaging machine for Ganoderma tea drinks and a packaging process which can avoid the local wrinkling of the barrier film caused by the relaxation of the barrier film under pressure during packaging.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] Please refer to Figures 1-6 The present application is a paper cup packaging machine for ganoderma tea drinking, which comprises: A base 1 is provided, which is divided into a cover film area and a packaging area. A packaging table 2 is slidably installed on the base 1 and is driven by a first driving source to reciprocally move in the cover film area and the packaging area. A paper cup 10 is fixedly installed on the packaging table 2 by a clamping assembly. A lifting frame 3 is slidably installed on the base 1 and is driven by a second driving source to lift. The lifting frame 3 is located in the cover film area and is fixedly installed with a vacuum suction rod 4 at the bottom end. The vacuum suction rod 4 is used to adsorb and place a barrier film 5 on the paper cup 10, so that the barrier film 5 is coaxially arranged with the paper cup 10. A hot pressing support 6 is fixedly installed on the base 1 and is located in the packaging area. A hot pressing head 7 is slidably installed at one end of the hot pressing support 6 and is driven by a third driving source to lift. The hot pressing head 7 is used to package the barrier film 5 and the paper cup 10. A first circular ring 11 is fixedly installed on the packaging table 2, and the paper cup 10 is located between the first circular rings 11. Four circumferentially arranged tensioning assemblies are arranged on the first circular ring 11. When the vacuum suction rod 4 places the barrier film 5 on the paper cup 10, the tensioning assemblies tension the barrier film 5, and then the packaging table 2 moves to the position directly below the hot pressing head 7.

[0019] Specifically, the clamping assembly comprises clamping cylinders 8 and abutting blocks 9, both of the clamping cylinders 8 are fixedly installed on the packaging table 2, and the two clamping cylinders 8 are symmetrically arranged about the paper cup 10, the movable end of each clamping cylinder 8 is fixedly installed with an abutting block 9, the inner surface of the abutting block 9 facing the paper cup 10 is concave, and the outer surface of the paper cup 10 is fitted to the concave surface of the abutting block 9.

[0020] In one case of the embodiment, the first driving source, the second driving source and the third driving source can be selected from electric telescopic rods, hydraulic rods and other mechanisms capable of realizing linear reciprocating motion, and the embodiment does not make specific limitations here; it should be noted that the vacuum adsorption rod 4, the hot pressing head 7 and the clamping cylinder 8 described in the application are prior art, and the application does not improve them, therefore, the specific mechanical structure and circuit structure of them do not need to be disclosed, and the integrity of the application is not affected.

[0021] The working principle of the application is as follows: first, the paper cup 10 containing the Ganoderma lucidum tea beverage is fixed on the packaging table 2 by the clamping assembly, the clamping cylinder 8 drives the abutting blocks 9 to move towards each other, the inner concave surface of the abutting block 9 is fitted to the outer surface of the paper cup 10, the stable clamping of the paper cup 10 is realized, and the paper cup 10 is prevented from deviating in the subsequent moving or tensioning process, then the first driving source drives the packaging table 2 to move to the position directly below the vacuum adsorption rod 4 in the film covering area, the second driving source drives the lifting frame 3 to descend, the barrier film 5 adsorbed by the vacuum adsorption rod 4 is close to the paper cup 10, until the vacuum adsorption rod 4 stably places the barrier film 5 at the top opening of the paper cup 10, at this time, the barrier film 5 is coaxial with the paper cup 10, the initial covering position is accurate, then the four tensioning assemblies on the first circular ring 11 act synchronously, and uniformly pull the barrier film 5 from the circumferential direction of the barrier film 5, so as to eliminate the slack of the barrier film 5, and make the barrier film 5 completely and flatly cover the top end of the paper cup 10, solve the problem of wrinkles of the barrier film 5 caused by no tensioning in the traditional packaging, finally, the first driving source drives the packaging table 2 to move to the position directly below the hot pressing head 7 in the packaging area, the third driving source drives the hot pressing head 7 to descend, and the barrier film 5 is tightly abutted on the edge of the paper cup 10, the hot pressing is realized through the preset temperature and pressure of the hot pressing head 7, and the sealing property of the packaging is ensured.

[0022] As Figures 1-5As shown, as a preferred embodiment of the present application, each of the tensioning assemblies comprises a positioning block 13, a moving frame 14, an upper clamping plate 15 and a lower clamping plate 16, the positioning block 13 is arranged on the first ring 11, the moving frame 14 is slidingly installed on the positioning block 13, the moving frame 14 is driven to move by a linkage assembly, the moving frame 14 moves along the radial direction of the paper cup 10, the linkage assembly is connected with the lifting frame 3, the moving frame 14 is designed as an open end towards one end of the paper cup 10, the lower clamping plate 16 is fixedly installed in the moving frame 14, the horizontal height of the lower clamping plate 16 is consistent with the horizontal height of the top end of the paper cup 10, the upper clamping plate 15 is slidingly installed in the moving frame 14, and the upper clamping plate 15 is located above the lower clamping plate 16, the upper clamping plate 15 is driven to lift by a power source, when the vacuum suction rod 4 adsorbs the barrier film 5, the second driving source drives the lifting frame 3 to descend so that the barrier film 5 approaches the paper cup 10, at this time, the lifting frame 3 drives the moving frame 14 to approach the paper cup 10 through the linkage assembly, when the barrier film 5 adheres to the top end of the paper cup 10, the edge of the barrier film 5 covers the top end of the upper clamping plate 15, at this time, the power source drives the upper clamping plate 15 to rise, so that the edge of the barrier film 5 is folded to between the upper clamping plate 15 and the lower clamping plate 16, then the power source drives the upper clamping plate 15 to descend to clamp and fix the edge of the barrier film 5, then the lifting frame 3 rises to drive the moving frame 14 to move away from the paper cup 10 through the linkage assembly, so as to tension the barrier film 5.

[0023] In actual application, when the lifting frame 3 drives the vacuum suction rod 4 and the barrier film 5 to descend and approach the paper cup 10, the linkage assembly synchronously drives the moving frame 14 to move towards the paper cup 10, so that the open end of the moving frame 14 approaches the outer edge of the paper cup 10, ensuring that after the barrier film 5 covers the paper cup 10, the edge thereof can naturally lap over the top end of the upper clamping plate 15, after the barrier film 5 adheres to the top end of the paper cup 10, the power source drives the upper clamping plate 15 to rise, so that the edge of the barrier film 5 is folded upwards and pressed towards the lower clamping plate 16, it should be noted that the barrier film 5 itself is elastic, when the edge of the barrier film 5 covers the top of the upper clamping plate 15, the rising of the upper clamping plate 15 will drive the edge of the barrier film 5 to move, and when the upper clamping plate 15 rises to a certain height, the edge of the barrier film 5 will move to between the lower clamping plate 16 and the upper clamping plate 15, and then the upper clamping plate 15 descends to clamp the edge of the barrier film 5 together with the lower clamping plate 16, realizing temporary fixing of the barrier film 5, then the lifting frame 3 rises to reset, at the same time, the linkage assembly drives the moving frame 14 to move outward along the radial direction of the paper cup 10, the four moving frames 14 synchronously pull the edge of the barrier film 5, using the radial tension to eliminate the slack and wrinkles of the barrier film 5, so as to keep the barrier film 5 in a flat state, providing a good foundation for subsequent hot-press packaging.

[0024] As Figures 1-5As shown, as a preferred embodiment of the present application, the linkage assembly comprises telescopic frame 21, second spring 22, roller 23, moving frame 24, trigger plate 25, extension rod 27 and bevel 28, four extension rods 27 are fixedly installed on lifting frame 3, and each extension rod 27 corresponds to a positioning block 13, the moving frame 24 is arranged on the extension rod 27, the trigger plate 25 is fixedly installed at the bottom end of the moving frame 24, the bevel 28 is arranged at the bottom end of the trigger plate 25, the bevel 28 is arranged obliquely, and the horizontal height of the end of the bevel 28 close to the paper cup 10 is higher than that of the end of the bevel 28 away from the paper cup 10, the telescopic frame 21 is slidingly installed on the positioning block 13, and one end of the telescopic frame 21 penetrates the positioning block 13 and is fixedly connected with the moving frame 14, the other end of the telescopic frame 21 is connected with the positioning block 13 through the second spring 22, the pre-tightening force of the second spring 22 makes the telescopic frame 21 away from the paper cup 10, the roller 23 is rotatably installed at the end of the telescopic frame 21 away from the moving frame 14, and the roller 23 is aligned with the bevel 28, when the lifting frame 3 descends, the bevel 28 rolls with the roller 23, the bevel 28 extrudes the roller 23 to make the telescopic frame 21 and the moving frame 14 close to the paper cup 10, and when the edge of the barrier film 5 covers the top end of the clamping plate 15, the roller 23 rolls with one side of the trigger plate 25.

[0025] Specifically, the power source comprises first spring 17, driven rack plate 18, transmission gear 19, driving rack plate 20 and electric cylinder 26, the upper clamping plate 15 is connected with the inner wall of the moving frame 14 through the first spring 17, the pre-tightening force of the first spring 17 makes the upper clamping plate 15 descend, the driven rack plate 18 and the driving rack plate 20 are slidingly installed in the moving frame 14, the driven rack plate 18 is fixedly connected with the upper clamping plate 15, the transmission gear 19 is rotatably installed in the moving frame 14, the transmission gear 19 is located between the driven rack plate 18 and the driving rack plate 20, and the opposite sides of the driven rack plate 18 and the driving rack plate 20 are engaged with the driving rack plate 20, the top end of the driving rack plate 20 penetrates the top of the moving frame 14, the electric cylinder 26 is fixedly installed on the moving frame 24, and the electric cylinder 26 is located above the driving rack plate 20, when the edge of the barrier film 5 covers the top end of the clamping plate 15, the electric cylinder 26 is opened to push the driving rack plate 20 to descend, the driving rack plate 20 drives the driven rack plate 18 to rise through the transmission gear 19, and the driven rack plate 18 drives the upper clamping plate 15 to rise and compresses the first spring 17.

[0026] In one case of the present embodiment, it should be noted that the moving frame 24 of the present application is a prior art, and the present application does not improve them, therefore, their specific mechanical structure and circuit structure do not need to be disclosed, and the integrity of the present application is not affected.

[0027] In actual application, during the descending process of the lifting frame 3, the trigger plate 25 descends synchronously with the lifting frame 3, the inclined edge 28 is in contact with the roller 23 and generates rolling extrusion. Due to the inclined design of the inclined edge 28, the extrusion force pushes the roller 23 to drive the telescopic frame 21 to move towards the paper cup 10 against the pre-tightening force of the second spring 22, thereby making the moving frame 14 close to the paper cup 10, realizing the linkage of the descending action of the moving frame 14 and the lifting frame 3, and simplifying the structure without additional driving source. When the edge of the barrier film 5 covers the top end of the clamping plate 15, the roller 23 has rolled to the vertical side of the trigger plate 25, and at this time the position of the moving frame 14 is fixed. To be precise, after the moving frame 14 moves to the position close to the paper cup 10, the barrier film 5 has not covered the top of the paper cup 10, so the lifting frame 3 can continue to descend, so that the barrier film 5 covers the top of the paper cup 10, and at the same time the edge of the barrier film 5 covers the top of the clamping plate 15. At this time, the electric cylinder 26 is started, pushing the driving rack plate 20 to slide downward, the driving rack plate 20 drives the driven rack plate 18 to move upward through the meshing transmission gear 19, and the driven rack plate 18 synchronously pulls the upper clamping plate 15 to rise, completing the preparation for folding the edge of the barrier film 5. After the barrier film 5 is clamped and fixed, the electric cylinder 26 is reset, and the upper clamping plate 15 descends under the pre-tightening force of the first spring 17 and clamps the barrier film 5 with the lower clamping plate 16. The whole process realizes precise control through mechanical linkage, avoiding damage to the barrier film 5 during clamping. After the lifting frame 3 rises, the trigger plate 25 also rises, so the pre-tightening force of the second spring 22 pushes the telescopic frame 21 away from the paper cup 10. At this time, the moving frame 14 moves away from the paper cup 10, so the upper clamping plate 15 and the lower clamping plate 16 clamp and stretch the barrier film 5, thereby ensuring that the barrier film 5 is completely unfolded, avoiding wrinkles of the barrier film 5 when the hot pressing head 7 abuts.

[0028] As shown in Figures 1-6 As a preferred embodiment of the present application, a limiting block 12 is fixedly installed on the first circular ring 11, the positioning block 13 is slidably installed on the limiting block 12, four circumferentially arranged straight grooves 29 are formed in the first circular ring 11, a cam 32 is fixedly installed at the bottom of the positioning block 13, the cam 32 is slidably installed in the straight groove 29, the cam 32 is driven to move by a synchronous assembly, a moving frame 24 is slidably installed on an extension rod 27, and the moving frame 24 is driven to move by a fourth driving source. The moving frame 24 and the positioning block 13 move radially along the paper cup 10.

[0029] Specifically, the synchronous assembly includes a second circular ring 30 and an inclined groove 31. The second circular ring 30 is rotatably installed in the first circular ring 11 and is driven to rotate by an output source. Four inclined grooves 31 are formed in the second circular ring 30, and each inclined groove 31 corresponds to a straight groove 29. The bottom end of the cam 32 is slidably installed in the inclined groove 31.

[0030] In one case of the embodiment, the fourth driving source can be selected from an electric telescopic rod, a hydraulic rod and the like, and can also be selected from other mechanisms capable of realizing linear reciprocating motion. The output source can be selected from a gear and an external gear ring meshing assembly driven by a motor. Specifically, the external gear ring is fixedly installed on the outer circumferential surface of the second ring 30, and the motor is fixedly installed in the first ring 11. The external gear ring and the second ring 30 are driven to rotate by the motor-driven gear. Other mechanisms capable of realizing rotary motion can also be selected, which are not specifically limited in the embodiment.

[0031] In actual application of the embodiment, considering that the paper cup 10 will be replaced in actual production, and the diameters of the cup mouths of different paper cups 10 are different, the diameters of the required barrier films 5 are also different. When it is required to adapt to paper cups 10 of different diameters, the output source drives the second ring 30 to rotate. The inclined grooves 31 on the second ring 30 drive the four cams 32 to move synchronously along the straight grooves 29 through the sliding cooperation with the cams 32, so as to adjust the radial positions of the positioning blocks 13 along the limiting blocks 12, so that the moving frame 14 can always adapt to the outer edges of the barrier films 5 of different diameters, improving the versatility of the equipment. At the same time, the fourth driving source drives the moving frame 24 to slide along the extension rod 27, adjusts the radial positions of the trigger plate 25 and the electric cylinder 26, so that the bevel edge 28 can be accurately aligned with the roller 23, and the electric cylinder 26 can be accurately aligned with the driving rack plate 20, so as to ensure that the linkage assembly and the power source can still work normally after the positioning block 13 is adjusted in position, avoid misplacement of the mechanism caused by the change of the diameter of the barrier film 5, ensure the stability of the tensioning effect, and the telescopic extension of the clamping cylinder 8 can control the abutting block 9 to clamp the paper cup 10 of different diameters.

[0032] Referring to Figures 1-6 The present application is a kind of paper cup packaging process for Ganoderma tea, which is applied to the paper cup packaging machine for Ganoderma tea as described in the above embodiment. The process comprises the following steps: Step S1: First, place the paper cup 10 containing Ganoderma tea on the packaging table 2, and clamp and fix the paper cup 10 by the clamping assembly; Step S2: Move the packaging table 2 to below the vacuum suction rod 4 by the first driving source, and then suction the barrier film 5 by the vacuum suction rod 4.
