Description

Technical Field

[0001] This utility model belongs to the field of paper cup processing technology, and in particular relates to a paper cup double-sided food-grade wax coating machine. Background Technology

[0002] The paper cup double-sided food-grade wax coating machine is a mechanical device specifically designed to uniformly coat the inner and outer surfaces of paper cups with food-grade wax.

[0003] In traditional paper cup production, waxing is typically done using atomizing nozzles to coat the outer and inner walls of the cup separately. This method increases the number of coating steps per cup. Since paper cup production involves a large number of cups, this significantly reduces the processing efficiency of the coating process, resulting in lower paper cup production output. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided food-grade wax coating machine for the inner and outer walls of paper cups. Specifically, during wax coating, an electric push rod is activated, pushing the lifting seat downwards to move the conveyor pipe to the top of the inner side of the paper cup, while the L-shaped connecting pipe moves to the outer side. Then, the motor is activated to drive the rear gear to rotate, which in turn drives the conveyor pipe to rotate on the rotary joint via the front gear transmission. This allows for wax coating in a rotating manner, simultaneously coating both the inner and outer walls of the paper cup without requiring separate coating. This improves work efficiency and solves the problem of traditional paper cup wax coating methods, which typically use atomizing nozzles to coat the outer and inner walls separately. Due to the large production volume of paper cups, this method significantly reduces coating efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a double-sided food-grade wax coating machine for the inner and outer walls of paper cups, comprising a base, a belt conveyor fixedly connected to the top of the base, a belt inside the belt conveyor, and a coating box installed on the outside of the belt conveyor, and further comprising:

[0007] A coating mechanism, described above, is disposed inside a coating chamber. The coating mechanism includes a lifting base disposed inside the coating chamber. A rotating assembly is disposed at the bottom of the lifting base. The rotating assembly includes a conveying pipe disposed at the bottom of the lifting base. An L-shaped connecting pipe is fixedly connected to the outside of the conveying pipe. Atomizing nozzles are installed on the inside of the L-shaped connecting pipe and at the bottom of the conveying pipe. A rotary joint is fixedly connected inside the lifting base. A flexible hose is connected to the top of the rotary joint. The bottom of the rotary joint is rotatably connected to the top of the conveying pipe.

[0008] A clamping mechanism is disposed on the surface of the belt;

[0009] The rotary joint is connected to the conveying pipe, and the conveying pipe is connected to the L-shaped connecting pipe, which is L-shaped.

[0010] Furthermore, several positioning blocks are fixedly connected to the outer surface of the belt, and paper cups are inserted inside the positioning blocks. The belt conveys the paper cups through the positioning blocks. The coating box has openings on both the left and right sides. The several positioning blocks are driven by the belt, allowing the staff to put the paper cups into the positioning blocks in sequence.

[0011] Furthermore, a controller is installed on the front of the coating box, and an electric push rod is fixedly connected to the top of the coating box. The bottom output end of the electric push rod is fixedly connected to the top of the lifting seat by screws. A circular hole is opened at the center of the top of the coating box, and the flexible hose is placed in the circular hole. The electric push rod is used to drive the lifting seat to rise and fall. When the lifting seat moves upward, the paper cup can be smoothly conveyed. When the lifting seat moves downward, the conveying pipe and the L-shaped connecting pipe move to the outside of the paper cup.

[0012] Furthermore, a support plate and a baffle are fixedly connected to the bottom of the lifting seat. A motor is fixedly connected to the bottom of the support plate. Gears are fixedly connected to the top output end of the motor and the outside of the conveying pipe. The two gears are meshed together. When the motor is started, the rear gear drives the front gear to rotate, and the conveying pipe rotates on the rotary joint, thereby spraying in a rotating manner.

[0013] The baffle is used to cover the two gears, and the L-shaped connecting pipe is located below the motor.

[0014] Furthermore, a limiting rod is slidably connected inside the lifting seat, and a support block is fixedly connected to the top and bottom of the limiting rod. The back of the support block is fixedly connected to the inner wall of the coating box. The limiting rod is used to limit the lifting seat, making the lifting seat more stable when it is raised and lowered.

[0015] Furthermore, the clamping mechanism includes several limiting grooves formed inside the positioning block. A connecting plate is slidably connected inside the limiting groove. A clamping shaft and a limiting shaft are fixedly connected to the side of the connecting plate facing the paper cup. A spring is fixedly connected to the side of the limiting shaft away from the connecting plate. The connecting plate is used to connect the clamping shaft and the limiting shaft to each other, so that the two can move simultaneously.

[0016] The clamping shaft is positioned above the limiting shaft, and the side of the clamping shaft facing the paper cup is spherical, with the spherical surface of the clamping shaft in contact with the surface of the paper cup.

[0017] Furthermore, the clamping shaft slides through the positioning block and extends to the outside, the limiting shaft is slidably connected inside the positioning block, and the side of the spring away from the limiting shaft is fixedly connected to the inner wall of the positioning block.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, through the setting of a coating mechanism, specifically, during waxing, the electric push rod is activated, pushing the lifting seat downwards, causing the conveying pipe to move to the top position inside the paper cup, and the L-shaped connecting pipe to move to the outer position outside the paper cup. Then, the motor is activated to drive the rear gear to rotate, and through the front gear transmission, the conveying pipe rotates on the rotary joint. This allows for waxing in a rotating manner, and can simultaneously coat both the inner and outer walls of the paper cup with wax, eliminating the need to coat the inner and outer walls of the paper cup separately, thus improving work efficiency.

[0020] 2. This utility model features a clamping mechanism. Specifically, the paper cup is placed inside the positioning block, and the clamping shaft is pushed. At this time, the connecting plate is pushed, and the spring is pulled by the limiting shaft. Then, the clamping shaft clamps and fixes the paper cup through the elastic force. This method is a flexible clamping method and will not clamp too tightly. It can quickly place and fix the paper cup. After the paper cup is fixed, it can be more stable during transportation. At the same time, the paper cup can be taken out by pulling it upward, which is convenient for disassembly.

Atomizing nozzles 223 are installed on the inside of the L-shaped connecting pipe 222 and at the bottom of conveying pipe 221. A rotary joint 225 is fixedly connected inside lifting base 21. A flexible hose 226 is connected to the top of rotary joint 225. The bottom of rotary joint 225 is connected to the top of conveying pipe 221. The system features a rotating connection. During waxing, the electric push rod 122 is activated, pushing the lifting seat 21 downwards. This moves the conveying pipe 221 to the top inner side of the paper cup 113, and the L-shaped connecting pipe 222 to the outer side of the paper cup 113. Then, the motor 213 is activated, driving the rear gear 224 to rotate. This, in turn, drives the conveying pipe 221 to rotate on the rotary joint 225 via the front gear 224. This allows for waxing in a rotating manner, simultaneously waxing both the inner and outer walls of the paper cup 113, eliminating the need for separate waxing and improving work efficiency.

[0033] The clamping mechanism 3 is disposed on the surface of the belt 111; the rotary joint 225 is connected to the conveying pipe 221, and the conveying pipe 221 is connected to the L-shaped connecting pipe 222, which is L-shaped.

[0034] Several positioning blocks 112 are fixedly connected to the outer surface of the belt 111. Paper cups 113 are inserted into the positioning blocks 112. The belt 111 conveys the paper cups 113 through the positioning blocks 112. The coating box 12 has openings on the left and right sides.

[0035] A controller 121 is installed on the front of the coating box 12. An electric push rod 122 is fixedly connected to the top of the coating box 12. The bottom output end of the electric push rod 122 is fixedly connected to the top of the lifting seat 21 by screws. A round hole is opened at the center of the top of the coating box 12, and a flexible hose 226 is placed in the round hole.

[0036] The bottom of the lifting seat 21 is fixedly connected to a support plate 211 and a baffle 212. The bottom of the support plate 211 is fixedly connected to a motor 213. The top output end of the motor 213 and the outside of the conveying pipe 221 are both fixedly connected to gears 224, and the two gears 224 are meshed together. The baffle 212 is used to cover the two gears 224. The L-shaped connecting pipe 222 is located below the motor 213.

[0037] The lifting seat 21 has a sliding connection to a limit rod 214 inside. The top and bottom of the limit rod 214 are fixedly connected to support blocks 215. The back of the support blocks 215 is fixedly connected to the inner wall of the coating box 12.

[0038] The clamping mechanism 3 includes several limiting grooves formed inside the positioning block 112. A connecting plate 31 is slidably connected inside the limiting groove. A clamping shaft 32 and a limiting shaft 33 are fixedly connected to the side of the connecting plate 31 facing the paper cup 113. A spring 34 is fixedly connected to the side of the limiting shaft 33 away from the connecting plate 31. When the paper cup 113 is placed into the positioning block 112 and the clamping shaft 32 is pushed, the connecting plate 31 is pushed and the spring 34 is pulled by the limiting shaft 33. Then, the spring force causes the clamping shaft 32 to clamp and fix the paper cup 113. This method is flexible clamping and will not clamp too tightly. It can quickly place and fix the paper cup 113. After the paper cup 113 is fixed, it can be more stable during conveying. At the same time, the paper cup 113 can be removed by pulling it upward, which is convenient for disassembly. The clamping shaft 32 is set above the limiting shaft 33. The side of the clamping shaft 32 facing the paper cup 113 is spherical and the spherical surface on the clamping shaft 32 is in contact with the surface of the paper cup 113.

[0040] One specific application of this embodiment is:

[0041] In use, connect the flexible hose 226 to the wax delivery pump to deliver wax into the hose 226. Then, place the paper cup 113 into the positioning block 112. When the paper cup 113 is inserted into the positioning block 112, it will push the clamping shaft 32. At this time, the connecting plate 31 is pushed, and the spring 34 is pulled through the limiting shaft 33. Then, the spring force causes the clamping shaft 32 to clamp and fix the paper cup 113. This method is a flexible clamping method, which will not clamp too tightly and can quickly place the paper cup 113. Fixed, the paper cup 113 is conveyed into the coating box 12 by the belt conveyor 111 driven by the belt conveyor 111. When the paper cup 113 moves directly below the conveyor pipe 221, the conveying stops. Then, the controller 121 controls the electric push rod 122 to start, pushing the lifting seat 21 downward. The lifting seat 21 slides on the limit rod 214, causing the conveyor pipe 221 to move to the top of the inner side of the paper cup 113. The L-shaped connecting pipe 222... Move the paper cup 113 to the outside position, then the electric push rod 122 stops, and then the control motor 213 starts. The rear gear 224 drives the front gear 224 to rotate, and the conveying pipe 221 rotates on the rotary joint 225. The rotary joint 225 is designed to smoothly convey the wax liquid and allow the conveying pipe 221 to rotate smoothly. Then, the wax liquid is sprayed out through the atomizing nozzle 223, simultaneously coating the outer and inner surfaces of the paper cup 113, thus quickly completing the waxing process. This method eliminates the need to separately wax the inner and outer walls of the paper cup 113, improving work efficiency. After the spraying is completed, the conveying pipe 221 stops rotating, and the electric push rod 122 drives the lifting seat 21 to return to its original position. Then, the belt conveyor 11 drives the belt 111 to transmit power, and the paper cup 113 is coated in the same way. The coated paper cup 113 is then conveyed to the outside of the coating box 12, and then the staff pulls the paper cup 113 out.
