Description

Technical Field

[0001] The utility model belongs to the technical field of paper cup production, and particularly relates to a glue-free environmentally friendly paper cup bonding process device. Background Art

[0002] Paper cups are made by mechanically processing and gluing paper made from chemical wood pulp. They are cup-shaped and waxed for frozen food, and can hold ice cream, jam, butter, etc. Paper cups are safe, hygienic, lightweight, and convenient. They can be used in public places, hotels, and restaurants, and are disposable items. Eco-friendly paper cups are made of environmentally friendly materials. The production process requires printing, cutting, gluing, and bonding. Glue-free eco-friendly paper cups use heat to melt the PE film on one side of the cardboard and bond it to the other side, eliminating the need for glue. This makes the paper cups more environmentally friendly and healthy.

[0003] When working, the paper cup bonding device usually wraps the paper cup on the forming cylinder, and then uses the downward pressure of the heating strip to melt the PE film and bond it to the paper cup. However, the existing device has difficulty in accurately controlling the contact time between the heating strip and the cardboard. If the contact time between the heating strip and the cardboard is too short, the PE film will not be completely melted, resulting in a weak bond. If the contact time is too long, it will easily damage the cardboard and may also cause the PE film in the non-pressed area to melt, causing the PE film to separate from the cardboard, affecting the production quality of the paper cup. Utility Model Content

[0004] The purpose of the utility model is to provide a glue-free and environmentally friendly paper cup bonding process device, which can adjust and control the contact time between the heating strip and the paperboard, thereby ensuring the bonding effect of the paper cup.

[0005] The technical solutions adopted by this utility model are as follows:

[0006] A glue-free, environmentally friendly paper cup bonding process device comprises a base, wherein the rear end of the upper surface of the base is fixedly connected to the bottom end of a vertical plate, the upper end of the vertical plate is fixedly connected to the rear end of a support plate, and the bottom surface of the support plate is fixedly connected to the upper ends of two telescopic rods, and the bottom ends of the two telescopic rods are fixedly connected to the upper end of the fixed plate;

[0007] The middle portion of the upper surface of the fixed plate is fixedly connected to the bottom end of the lifting plate, and tooth plates 1 are fixedly provided on the left and right side surfaces of the lifting plate.

[0008] A heating plate is fixedly arranged on the bottom surface of the fixed plate, and the two tooth plates are respectively meshed and connected with the two residual gears.

[0009] The two residual gears are respectively fixedly arranged at the front ends of the two rotating shafts, and the two rotating shafts are rotationally connected to the vertical plate through rolling bearings.

[0010] Sprockets are fixedly provided at the rear ends of the two rotating shafts, and the two sprockets are connected via a chain transmission.

[0011] The rear end of the rotating shaft on the right is also fixedly connected to the output shaft of the motor, and the motor is fixedly connected to the rear end of the vertical plate through a mounting seat.

[0012] The rear end of the fixed plate is fixedly connected to the front end of the connecting plate. The connecting plate is sleeved in the through slot opened on the vertical plate. The rear end of the connecting plate is fixedly connected to the second tooth plate.

[0013] The second tooth plate is meshed with a gear, and the gear is fixedly arranged at the rear end of the nozzle.

[0014] The nozzle is rotatably connected to the vertical plate through a rolling bearing, and the rear end of the nozzle is rotatably connected to the air outlet pipe of the air cooler through a sealing bearing.

[0015] The air cooler is fixedly connected to the rear end of the fixing frame, the front end of the fixing frame is fixedly connected to the rear end of the vertical plate, and a mold column is also fixedly provided on the front side of the vertical plate.

[0016] The technical effects achieved by this utility model are:

[0017] When the utility model is in use, the cardboard can be wrapped around the mold column, and then the motor is controlled to drive the two rotating shafts and the residual gears to rotate counterclockwise. When the right residual gear rotates to engage with the right tooth plate 1, the lifting plate, the fixed plate and the heating plate are driven to descend. When the right residual gear is disengaged from the right tooth plate 1, the heating plate contacts the cardboard on the mold column to hot-melt the PE film pressed on the cardboard so that the cardboard is bonded. As the motor continues to run, when the left residual gear rotates to engage with the left tooth plate 1, the lifting plate, the fixed plate and the heating plate are driven to rise so that the heating plate is separated from the cardboard to complete the bonding operation. The cooperation of the residual gears and the tooth plate 1 on both sides is used to make the heating plate contact with the cardboard for a corresponding time to perform the bonding operation. The motor speed can be adjusted to change the speed of the residual gears on both sides, thereby changing the window period when the residual gears on both sides are engaged with the tooth plate 1 to adjust the contact time of the heating plate and the cardboard, thereby effectively improving the production quality of paper cups.

[0018] The utility model provides a nozzle on the right side of the mold column, and provides a connecting plate, a second tooth plate, and a gear to realize linkage between the nozzle and the fixed plate. When the fixed plate drives the heating plate to descend for bonding, the fixed plate drives the nozzle to rotate counterclockwise through the connecting plate, the second tooth plate, and the gear, so that the nozzle on the nozzle deviates from the mold column, thereby preventing the cold air flow ejected by the nozzle from cooling the heating plate and affecting the hot melting of the PE film. When bonding is completed, the fixed plate moves up and drives the nozzle to rotate clockwise so that the nozzle on the nozzle corresponds to the mold column. At this time, the cold air ejected by the nozzle is used to cool the bonding position of the paperboard, so that the molten PE film is quickly cooled for bonding, thereby effectively improving the production efficiency of paper cups.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, a glue-free environmentally friendly paper cup bonding process device includes a base 1, the rear end of the upper surface of the base 1 is fixedly connected to the bottom end of the vertical plate 3, the upper end of the vertical plate 3 is fixedly connected to the rear end of the support plate 4, and the bottom surface of the support plate 4 is also fixedly connected to the upper ends of two telescopic rods 5. The bottom ends of the two telescopic rods 5 are fixedly connected to the upper end of the fixed plate 8. By providing the telescopic rods 5 connected to the fixed plate 8, the telescopic rods 5 are used to fix and support the fixed plate 8, effectively improving the stability of the fixed plate 8 when it is raised or lowered;

[0027] Furthermore, the middle portion of the upper surface of the fixed plate 8 is fixedly connected to the bottom end of the lifting plate 9 , and tooth plates 16 are fixedly provided on the left and right side surfaces of the lifting plate 9 .

[0028] Furthermore, a heating plate 15 is fixedly provided on the bottom surface of the fixed plate 8, and two tooth plates 16 are respectively engaged with the two residual gears 7.

[0029] Furthermore, the two residual gears 7 are fixedly arranged at the front ends of the two rotating shafts 6 respectively. The two rotating shafts 6 are rotatably connected to the vertical plate 3 through rolling bearings. When the right residual gear 7 rotates to engage with the right tooth plate 16, it drives the lifting plate 9, the fixed plate 8 and the heating plate 15 to descend. When the right residual gear 7 is disengaged from the right tooth plate 16, the heating plate 15 contacts the cardboard on the mold column 2 to heat-melt the PE film pressed on the cardboard so that the cardboard is bonded. As the motor 11 continues to run, when the left residual gear 7 rotates to engage with the left tooth plate 16, it drives the lifting plate 9, the fixed plate 8 and the heating plate 15 to descend. The descending plate 9, the fixing plate 8 and the heating plate 15 are raised so that the heating plate 15 is separated from the cardboard to complete the bonding operation. During this process, after the right residual gear 7 is separated from the right tooth plate 16 and before the left residual gear 7 is engaged with the left tooth plate 16, the heating plate 15 is always in contact with the cardboard to heat-melt the PE film pressed on the cardboard, and the user can adjust the speed of the motor 11 to change the speed of the residual gears 7 on both sides, thereby changing the window period when the residual gears 7 on both sides are engaged with the tooth plate 16 to adjust the contact time of the heating plate 15 and the cardboard.

[0030] Furthermore, sprockets 19 are fixedly provided at the rear ends of the two rotating shafts 6, and the two sprockets 19 are connected by a chain transmission.

[0031] Furthermore, the rear end of the right rotating shaft 6 is also fixedly connected to the output shaft of the motor 11, and the motor 11 is fixedly connected to the rear end of the vertical plate 3 through the mounting seat.

[0032] Furthermore, the rear end of the fixed plate 8 is fixedly connected to the front end of the connecting plate 13 , the connecting plate 13 is sleeved in the through slot 14 opened in the vertical plate 3 , and the rear end of the connecting plate 13 is fixedly connected to the tooth plate 2 20 .

[0033] Furthermore, tooth plate 20 is meshed with gear 17, and gear 17 is fixedly arranged at the rear end of nozzle 10. By arranging nozzle 10 on the right side of mold column 2, and arranging connecting plate 13, tooth plate 20, and gear 17, nozzle 10 and fixed plate 8 are linked. When fixed plate 8 drives heating plate 15 to descend for bonding operation, fixed plate 8 drives nozzle 10 to rotate counterclockwise through connecting plate 13, tooth plate 20, and gear 17, so that the nozzle on nozzle 10 deviates from mold column 2, thereby avoiding the cold air flow ejected from nozzle 10 to cool down heating plate 15 and affect the hot melting of PE film.

[0034] Furthermore, the nozzle 10 is rotatably connected to the vertical plate 3 via a rolling bearing, and the rear end of the nozzle 10 is rotatably connected to the air outlet pipe of the air cooler 12 via a sealed bearing.

[0035] Furthermore, the air cooler 12 is fixedly connected to the rear end of the fixing frame 18, and the front end of the fixing frame 18 is fixedly connected to the rear end of the vertical plate 3. The mold column 2 is also fixedly provided on the front side of the vertical plate 3. When the fixing plate 8 moves upward, the nozzle 10 is driven to rotate clockwise so that the nozzle on the nozzle 10 corresponds to the mold column 2. At this time, the cold air sprayed by the nozzle 10 is used to cool the bonding point of the cardboard, so that the molten PE film is quickly cooled and bonded, thereby effectively improving the production efficiency of the paper cup.

[0036] The working principle of the present utility model is as follows: when in use, the cardboard can be placed around the mold column 2, and then the motor 11, the heating plate 15 and the cooling fan 12 can be controlled to work. When the cooling fan 12 is working, cold air is generated and input into the nozzle 10 and ejected through the nozzle on the nozzle 10. When the motor 11 is working, it drives the two rotating shafts 6 and the residual gear 7 to rotate counterclockwise. When the right residual gear 7 rotates to engage with the right tooth plate 16, it drives the lifting plate 9, the fixed plate 8 and the heating plate 15 to descend. When the right residual gear 7 is disengaged from the right tooth plate 16, the heating plate 15 contacts the cardboard on the mold column 2 to heat-melt the PE film pressed on the cardboard so that the cardboard is bonded. When the fixed plate 8 drives the heating plate 15 to descend, the cardboard is pressed against the mold column 2. During the gluing operation, the fixed plate 8 drives the nozzle 10 to rotate counterclockwise through the connecting plate 13, the second tooth plate 20, and the gear 17, so that the nozzle on the nozzle 10 deviates from the mold column 2. As the motor 11 continues to run, when the left residual gear 7 rotates to engage with the left tooth plate 16, it drives the lifting plate 9, the fixed plate 8, and the heating plate 15 to rise, so that the heating plate 15 is separated from the cardboard, and the gluing operation is completed. At this time, the motor 11 is stopped, and the fixed plate 8 moves upward, driving the nozzle 10 to rotate clockwise so that the nozzle on the nozzle 10 corresponds to the mold column 2. At this time, the cold air ejected from the nozzle 10 is used to cool the bonding area of ​​the cardboard. Then, the user can remove the bonded paper cup from the mold column 2.
