Description

Technical Field

[0001] The present invention relates to the field of paper cup production, specifically to a one-step forming device and a usage method for paper cups. Background Art

[0002] As an indispensable disposable tableware in modern life, paper cups are widely used in places such as food delivery, coffee shops, fast food restaurants, convenience stores, etc., as well as daily drinking scenarios such as offices and meeting rooms. With the acceleration of the pace of life and the rise of the food delivery market, the demand for paper cups continues to increase.

[0003] During the process of processing a paper cup from a fan-shaped paper sheet, it usually needs to go through multiple processes such as feeding, gluing, shaping, and bonding and forming. Currently, the production process of paper cup processing procedures often involves multiple devices to perform processes such as feeding, gluing, shaping, and bonding and forming step by step. During the paper cup forming process, the paper cup blanks often need to be repeatedly transferred between multiple devices. This not only increases the number of devices, resulting in increased equipment investment and labor input costs, but also reduces the efficiency of paper cup forming and processing. For this reason, the present invention proposes a one-step forming device and a usage method for paper cups. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a one-step forming device and a usage method for paper cups to solve the technical problems of high cost and low efficiency existing in the current paper cup forming and processing that require multiple device operations.

[0005] To achieve the above object, the present invention provides the following technical solution: A one-step forming device for paper cups, including a fixed frame. The top end of the fixed frame has a table board.

A gluing electric push rod is vertically fixed to the bottom of the gluing frame. The telescopic end of the gluing electric push rod is vertically upward and connected to a glue box. The top end of the glue box movably penetrates the table board. The glue box is located between the moving paper cup forming die roller and the storage mechanism. The glue box is distributed parallel to one of the hypotenuses of the material cylinder. An impregnated cotton is embedded at the top of the shuttle glue box and protrudes from the upper end surface of the glue box. A glue injection port is arranged at the top of the side wall of the glue box. A glue discharge port is arranged at the bottom wall of the glue box.

[0010] The present invention is further configured such that a stop block is arranged on the outer wall of the smaller radius end of the static paper cup forming die roller. The stop block is located between the static paper cup forming die roller and the die sleeve. A pressing plate is arranged on the side of the die sleeve facing the glue box. The pressing plate is inclined upward.

[0011] The present invention is further configured such that the feeding mechanism includes a pair of fixing blocks fixed to the upper surface of the table board near the position of the material cylinder. A feeding shaft rod is rotatably installed between the pair of fixing blocks. A pair of fixing plates are rotatably sleeved on the feeding shaft rod. A feeding wheel is rotatably installed between the ends of the pair of fixing plates. A pulley is coaxially arranged on one side of the feeding wheel and on the feeding shaft rod. A synchronous belt is sleeved between the pair of pulleys. The feeding wheel rotatably presses against the fan-shaped paper pieces in the material cylinder.

A transfer electric push rod is vertically installed at the end of the cross arm. The telescopic end of the transfer electric push rod is vertically downward and is equipped with a suction cup. The suction cup is adapted to the outer surface of the paper cup and can adsorb the formed paper cup.

[0013] The present invention is further configured such that a connecting frame is fixed to the telescopic end of the transfer electric push rod. A cantilever is hinged to the bottom of the connecting frame. The suction cup is installed at the bottom end of the cantilever. A steering motor for driving the cantilever to swing is installed on one side of the connecting frame. A second guide rod is vertically fixed to the connecting frame and movably penetrates through the cross arm.

[0014] The usage method of the one-time forming device for paper cups includes the following steps:

[0015] Step 1: Preparation for paper cup forming. A number of fan-shaped paper pieces for making paper cups are pre-cut and stacked and loaded into the material cylinder. Glue for bonding the interfaces of the paper cups is poured into the glue box. The glue soaks the glue-soaked cotton. The feeding wheel is pushed to rotate around the feeding shaft rod and presses against the fan-shaped paper pieces in the material cylinder.

[0016] Step 2: Feeding and gluing. The feeding motor is started to drive the feeding shaft rod to rotate. Under the transmission cooperation of the pulleys and the synchronous belt, the feeding wheel is driven to rotate. The feeding wheel rotates to convey the uppermost fan-shaped paper piece in the material cylinder past the upper part of the glue box. The glue-applying electric push rod pushes the glue box upward to make the glue-soaked cotton contact and apply glue to one side of the fan-shaped paper piece parallel to it. At the same time, the leading end of the fan-shaped paper piece is lifted. The fan-shaped paper piece with the leading end lifted is sent between the moving paper cup forming die roller and the static paper cup forming die roller under the limiting cooperation of the pressing plate.

[0017] Step 3: Paper cup forming. Start the forming electric push rod to move the roller frame upward, so that the fan-shaped paper sheet is clamped between the moving paper cup forming die roller and the static paper cup forming die roller. Start the forming motor to drive the rotation of the moving paper cup forming die roller, so that the fan-shaped paper sheet penetrates between the static paper cup forming die roller and the die sleeve, and is bent and wound into a paper cup shape. After the fan-shaped paper sheet surrounds the static paper cup forming die roller for one circle, the forming electric push rod pushes the forming frame to move upward continuously, so that the moving paper cup forming die roller squeezes the overlapping parts at both ends of the fan-shaped paper sheet, and the two ends of the fan-shaped paper sheet are bonded with glue, and the paper cup is formed.

[0018] Step 4: Material discharging. Start the retracting of the discharging electric push rod. The discharging electric push rod drives the static paper cup forming die roller to disengage from the die sleeve through the connecting rod, and the static paper cup forming die roller cooperates with the stop block to drive the formed paper cup out of the die sleeve at the same time.

[0019] Step 5: Transfer of the formed paper cup. Start the transfer motor to drive the vertical rod to rotate, so that the suction cup is aligned with the formed paper cup pushed out of the die sleeve. Start the transfer electric push rod to push the suction cup downward to adsorb the formed paper cup on the static paper cup forming die roller. Immediately afterwards, the discharging electric push rod retracts again, and the formed paper cup disengages from the static paper cup forming die roller. Then the transfer electric push rod retracts, and the formed paper cup and the static paper cup forming die roller are vertically misaligned. The discharging electric push rod pushes the static paper cup forming die roller to embed into the die sleeve to continue the forming process of the next paper cup. Start the steering motor to drive the cantilever to rotate and swing to adjust the positive and negative angles of the formed paper cup. Start the transfer motor to drive the vertical rod to rotate, so that the formed paper cup adsorbed by the suction cup is transferred to the next process.

[0020] In summary, the present invention mainly has the following beneficial effects: Through the cooperation of the storage mechanism and the feeding mechanism, the neatly stacked fan-shaped paper sheets can be continuously transported between the moving paper cup forming die roller and the static paper cup forming die roller for the roll forming of the paper cup, realizing automatic feeding. Through the setting of the gluing mechanism, the fan-shaped paper sheets transported to between the moving paper cup forming die roller and the static paper cup forming die roller can be glued. Under the roll forming cooperation of the moving paper cup forming die roller, the static paper cup forming die roller and the die sleeve, the paper cup can be quickly formed and bonded, realizing the automatic roll forming of the paper cup. Through the setting of the discharging mechanism, the roll-formed paper cup can be automatically taken out of the die sleeve, and under the setting of the transfer mechanism, the formed paper cup can be disengaged from the static paper cup forming die roller and rotated and adjusted in angle and then transported to the next process. The whole integrates paper cup storage, automatic feeding, automatic gluing, automatic roll forming, automatic discharging, and automatic transfer, and can realize the one-time processing and forming of the paper cup, without the need for multiple equipment operations, realizing the assembly line production and processing of the paper cup, avoiding the frequent transfer and transportation of the paper cup between multiple equipment, reducing the repeated transfer process, being convenient for management and maintenance, reducing the labor cost and equipment cost, and at the same time greatly improving the production efficiency of the paper cup.

[0036] This embodiment also provides a method for using a one-time forming device for paper cups, including the following steps:

[0037] Step 1: Preparation for paper cup forming. Cut several fan-shaped paper sheets for making paper cups in advance. Stack the several fan-shaped paper sheets and load them into the material cylinder 10. Pour glue for bonding the paper cup joints into the glue box 15. The glue soaks the glue-soaked cotton 16. Push the feeding wheel 38 to rotate around the feeding shaft rod 36 and press it on the fan-shaped paper sheets in the material cylinder 10.

[0038] Step 2: Feeding and glue application. Start the feeding motor 41 to drive the feeding shaft rod 36 to rotate. Under the transmission and cooperation of the belt pulley 39 and the synchronous belt 40, drive the feeding wheel 38 to rotate. The feeding wheel 38 rotates to convey the uppermost fan-shaped paper sheet in the material cylinder 10 above the glue box 15. The glue application electric push rod 20 pushes the glue box 15 upward, making one side of the glue-soaked cotton 16 in contact with the fan-shaped paper sheet for glue application in parallel, and at the same time lifting the head end of the fan-shaped paper sheet. The fan-shaped paper sheet with the head end lifted is fed between the moving paper cup forming die roller 4 and the static paper cup forming die roller 24 under the limit cooperation of the pressing plate 28.

[0039] Step 3: Paper cup forming. Start the forming electric push rod 33 to push the roller frame 30 upward, clamping the fan-shaped paper sheet between the moving paper cup forming die roller 4 and the static paper cup forming die roller 24. Start the forming motor 31 to drive the moving paper cup forming die roller 4 to rotate, making the fan-shaped paper sheet pass through between the static paper cup forming die roller 24 and the die sleeve 25 and bend and wind into a paper cup shape. After the fan-shaped paper sheet winds around the static paper cup forming die roller 24 for one circle, the forming electric push rod 33 pushes the forming frame 32 to continue to move upward, so that the moving paper cup forming die roller 4 squeezes the overlapping parts at both ends of the fan-shaped paper sheet, and the two ends of the fan-shaped paper sheet are bonded with glue, and the paper cup is formed.

[0040] Step 4: Material discharging. Start the discharging electric push rod 29 to contract. The discharging electric push rod 29 drives the static paper cup forming die roller 24 to disengage from the die sleeve 25 through the connecting rod 23, and the static paper cup forming die roller 24 cooperates with the stop block 26 to drive the formed paper cup to disengage from the die sleeve 25 at the same time.

[0041] Step 5: Transfer of the formed paper cup. Start the transfer motor 43 to drive the vertical rod 42 to rotate, aligning the suction cup 48 with the formed paper cup pushed out of the die sleeve 25. Start the transfer electric push rod 45 to push the suction cup 48 downward to adsorb the formed paper cup on the static paper cup forming die roller 24. Immediately, the discharging electric push rod 29 contracts again, and the formed paper cup disengages from the static paper cup forming die roller 24. Then the transfer electric push rod 45 contracts, and the formed paper cup and the static paper cup forming die roller 24 are vertically misaligned. The discharging electric push rod 29 pushes the static paper cup forming die roller 24 into the die sleeve 25 to continue the next paper cup forming process.

10. Method of using a one - step forming device for paper cups, applicable to the one - step forming device for paper cups described in any one of claims 1 - 9, characterized in that, It includes the following steps: Step 1: Preparation for paper cup forming. A number of fan-shaped paper sheets for making paper cups are pre-cut. The number of fan-shaped paper sheets are stacked and loaded into the material cylinder (10). Glue for bonding the paper cup interfaces is poured into the glue box (15). The glue soaks the glue-impregnated cotton (16). The feeding wheel (38) is pushed to rotate around the feeding shaft rod (36) and press on the fan-shaped paper sheets in the material cylinder (10). Step 2: Feeding and gluing. The feeding motor (41) is started to drive the feeding shaft rod (36) to rotate. Under the transmission cooperation of the belt pulley (39) and the synchronous belt (40), the feeding wheel (38) is driven to rotate. The feeding wheel (38) rotates to convey the uppermost fan-shaped paper sheet in the material cylinder (10) above the glue box (15). The glue-applying electric push rod (20) pushes the glue box (15) upward, so that the glue-impregnated cotton (16) comes into side contact with the parallel side of the fan-shaped paper sheet for gluing, and at the same time, the leading end of the fan-shaped paper sheet is lifted. The fan-shaped paper sheet with the leading end lifted is fed between the moving paper cup forming die roller (4) and the static paper cup forming die roller (24) under the limiting cooperation of the pressing plate (28). Step 3: Paper cup forming. The forming electric push rod (33) is started to push the roller frame (30) upward, so that the fan-shaped paper sheet is clamped between the moving paper cup forming die roller (4) and the static paper cup forming die roller (24). The forming motor (31) is started to drive the moving paper cup forming die roller (4) to rotate, so that the fan-shaped paper sheet penetrates between the static paper cup forming die roller (24) and the die sleeve (25) and is bent and wound into a paper cup shape. After the fan-shaped paper sheet surrounds the static paper cup forming die roller (24) for one circle, the forming electric push rod (33) pushes the forming frame (32) to continue to move upward, so that the moving paper cup forming die roller (4) squeezes the overlapping parts at both ends of the fan-shaped paper sheet, and the two ends of the fan-shaped paper sheet are bonded with glue, and the paper cup is formed. Step 4: Unloading. The unloading electric push rod (29) is started to contract. The unloading electric push rod (29) drives the static paper cup forming die roller (24) to disengage from the die sleeve (25) through the connecting rod (23). The static paper cup forming die roller (24) cooperates with the stop block (26) to drive the formed paper cup to disengage from the die sleeve (25) at the same time. Step Five: Transfer the formed paper cups. Start the transfer motor (43) to drive the vertical rod (42) to rotate, align the suction cup (48) with the formed paper cups in the ejection die sleeve (25). Start the transfer electric push rod (45) to push the suction cup (48) downward to adsorb the formed paper cups on the static paper cup forming die roller (24). Immediately, the ejection electric push rod (29) contracts again, and the formed paper cups are separated from the static paper cup forming die roller (24). Then the transfer electric push rod (45) contracts, and the formed paper cups are vertically misaligned with the static paper cup forming die roller (24). The ejection electric push rod (29) pushes the static paper cup forming die roller (24) into the die sleeve (25) to continue the next paper cup forming process. Start the steering motor (49) to drive the cantilever (47) to rotate and swing to adjust the front and back angles of the formed paper cups. Start the transfer motor (43) to drive the vertical rod (42) to rotate, and transfer the formed paper cups adsorbed by the suction cup (48) to the next process.
