Description

Technical Field

[0001] This invention relates to the field of equipment for cleaning zongzi leaves, and more particularly to a fully automatic device for cleaning zongzi leaves. Background Technology

[0002] Zongzi, a traditional delicacy, is consumed in large quantities. The bamboo leaves are a crucial part of making zongzi. Since the leaves directly wrap the edible parts of the zongzi, their cleanliness is paramount. Zongzi production still largely relies on manual labor, especially the cleaning of bamboo leaves, which is often done manually or semi-automatically. Some food manufacturers even reduce cleaning costs by simply soaking and rinsing the leaves, posing a significant health risk to consumers. Therefore, it is necessary to provide an automated, efficient, and highly effective equipment for cleaning bamboo leaves. Summary of the Invention

[0003] The purpose of this invention is to solve the following problems existing in the prior art: the cleaning of zongzi leaves is still done manually or semi-automatically, and some food production enterprises even simply soak the zongzi leaves and rinse them with water in order to reduce cleaning costs. This poses a significant risk to people's health after consumption. Therefore, it is necessary to provide an automated, efficient, and highly clean zongzi leaf cleaning device.

[0004] To address the problems existing in the prior art, the present invention provides a fully automatic device for cleaning zongzi leaves, including a frame, feeding boxes on both sides of the frame, and a feeding assembly on the upper part of the frame;

[0005] Conveyor belts are arranged between the feeding hoppers;

[0006] A return water tank is located at the end of the conveyor belt away from the frame, and a receiving box is provided on the side of the return water tank away from the conveyor belt.

[0007] Cleaning rollers: Two rows of cleaning rollers are rotatably arranged above the return water tank, with the two rows of cleaning rollers aligned one above the other. The two aligned cleaning rollers are connected at one end by two meshing gears.

[0008] A drive unit, which is connected to a cleaning roller of the same height;

[0009] A water pump assembly, connected to the cleaning roller, is used to supply water to the cleaning roller.

[0010] Preferably, the cleaning roller includes a roller, one end of which is connected to the water pump assembly. A rubber layer is sleeved on the outside of the roller, forming a sealed liquid cavity between the roller and the rubber layer. An opening is provided on the surface of the roller to pass through the liquid cavity. A sponge layer covers the outer wall of the rubber layer. Several pressure valves are distributed in a ring on the surface of the rubber layer, and the liquid cavity is connected to the sponge layer through the pressure valves.

[0011] Preferably, the pressure valve includes a strip shell that extends through the rubber layer. The inner wall of the strip shell has several valve holes that penetrate the liquid chamber. Several valve balls are disposed inside the strip shell and are connected to the strip shell by springs. The valve balls are used to elastically fit the valve holes. The outer wall of the strip shell has through holes.

[0012] Preferably, the water pump assembly includes a water pump body, the outlet end of the water pump body is connected to a connecting pipe, the end of the roller is rotatably connected to the connecting pipe, and the output shaft of the water pump body is connected to one of the rollers via a conveyor belt.

[0013] Preferably, the driving device includes a motor, and sprockets are fixed to both the output shaft of the motor and the end of the cleaning roller. The sprockets are connected by chain drive, and the diameter of the sprockets gradually increases from the receiving box to the end of the cleaning roller in the direction of the conveyor belt.

[0014] Preferably, the feeding component includes a horizontal linear drive component, the moving end of which is connected to two vertically distributed vertical linear drive components, the moving end of which is connected to a lifting frame, and the bottom of the lifting frame is connected to a suction cup component.

[0015] Preferably, the suction cup assembly includes a box body, a sponge block is fixed to the bottom of the box body, a number of air holes penetrating the box body are opened on the surface of the sponge block, and two air ports are connected to the surface of the box body.

[0016] Compared with related technologies, the fully automatic equipment for cleaning zongzi leaves provided by this invention has the following beneficial effects:

[0017] 1. The suction cup assembly of the present invention uses a sponge to contact the bamboo leaves, which can stably arrange the bamboo leaves on the surface of the conveyor belt. The bamboo leaves are held and transferred by the cleaning roller, and the water pump delivers cleaning water, so as to realize the automated and efficient cleaning of bamboo leaves.

[0018] 2. In this invention, the cleaning roller is driven by a driving device to gradually increase its speed from front to back. The bamboo leaves are transmitted in the variable speed cleaning roller, causing friction between the cleaning roller and the surface of the bamboo leaves, which is used for deep cleaning of the bamboo leaves.

[0019] 3. In this invention, water is supplied to the liquid cavity, causing the rubber layer and sponge layer to expand and squeeze the bamboo leaves. Then, the washing water is introduced into the sponge layer from the inside to the outside. During the process of carrying the bamboo leaves, the sponge layer squeezes the bamboo leaves to discharge the washing water, quickly rinsing away the impurities on the surface of the bamboo leaves.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] Example 1

[0033] like Figure 1 , Figure 2 As shown, a fully automatic device for cleaning zongzi leaves includes a frame 1, with two feeding boxes 3 fixedly installed on both sides of the frame 1. The top opening of the feeding boxes 3 is open, and each feeding box 3 has multiple partitioned areas for placing multiple sets of vertically stacked zongzi leaves.

[0034] like Figure 7As shown, the feeding assembly 4 includes a horizontal linear drive assembly 41 and a vertical linear drive assembly 42. The horizontal linear drive assembly 41 and the vertical linear drive assembly 42 have the same structure and have a frame that slides linearly. A lead screw is rotatably installed on the surface of the frame, and a motor assembly is installed at one end of the frame to drive the lead screw to rotate. A moving assembly is slidably installed on the surface of the frame. The lead screw thread passes through the moving assembly. The motor drives the lead screw to rotate, and the thread drives the moving assembly to move linearly along the frame.

[0035] The horizontal linear drive assembly 41 has two moving components, which are respectively connected to and installed with vertically distributed vertical linear drive assemblies 42. The moving parts of the vertical linear drive assembly 42 are fixedly installed with lifting frame 43. The bottom of the lifting frame 43 has multiple legs, and each leg is connected to a suction cup assembly 44. The distribution of the suction cup assemblies 44 is the same as the distribution of the zongzi leaves in the feeding box 3.

[0036] like Figure 8 , Figure 9 As shown, the suction cup assembly 44 includes a box body 441, a sponge block 443 is fixedly installed at the bottom of the box body 441, the bottom of the sponge block 443 is a flat surface, and several air holes 444 penetrating the box body 441 are opened on the surface of the sponge block 443. Two air ports 442 are connected to the surface of the box body 441, and the two air ports 442 are used to connect the air pump assembly.

[0037] A conveyor belt 2 is installed in the middle of the frame 1, with one end of the conveyor belt 2 extending outwards and the conveyor belt 2 located between the feeding boxes 3;

[0038] The feeding principle is as follows:

[0039] The controller sets the working logic of the horizontal linear drive component 41 and the vertical linear drive component 42. The horizontal linear drive component 41 drives the two vertical linear drive components 42 to move left and right synchronously, so that the two vertical linear drive components 42 alternately align with the feeding box 3. The vertical linear drive component 42 pushes the lifting frame 43 and the suction cup component 44 downward to extend into the feeding box 3. The suction cup component 44 adsorbs the zongzi leaves and moves them upward. The suction cup component 44 alternately places the zongzi leaves on the surface of the conveyor belt 2. The zongzi leaves are then neatly transported to the washing stage by the conveyor belt 2.

[0040] When the bamboo leaves are adsorbed, the sponge block 443 presses against the surface of the bamboo leaves, so that the sponge block 443 and the bamboo leaves are completely adhered. The air pump component draws air from the air port 442, so that the air hole 444 generates negative pressure to adsorb the bamboo leaves.

[0041] The cleaning process is as follows:

[0042] like Figure 3 , Figure 4As shown, a funnel-shaped return water tank 6 is set at the end of the conveyor belt 2 away from the frame 1. Two sets of cleaning rollers 7 are arranged vertically on the top of the return water tank 6. The two sets of cleaning rollers 7 are aligned vertically. One end of the two vertically aligned cleaning rollers 7 is connected by two gears 81. A receiving box 5 is set on the side of the return water tank 6 away from the conveyor belt 2.

[0043] The drive unit is connected to a cleaning roller 7 of the same height;

[0044] like Figure 5 , Figure 6 As shown, the cleaning roller 7 includes a roller 71, one end of which is connected to a water pump assembly. A rubber layer 73 is sleeved on the outside of the roller 71, forming a sealed liquid cavity between the roller 71 and the rubber layer 73. An opening 72 through the liquid cavity is provided on the surface of the roller 71. A sponge layer 74 is covered on the outer wall of the rubber layer 73. Several pressure valves are distributed in a ring on the surface of the rubber layer 73. The liquid cavity is connected to the sponge layer 74 through the pressure valves. The pressure valve includes a strip shell 75, which is connected to the rubber layer 73. Several valve holes 78 through the liquid cavity are provided on the inner wall of the strip shell 75. Several valve balls 77 are provided inside the strip shell 75. The valve balls 77 are connected to the strip shell 75 by springs and are used to elastically fit the valve holes 78. A through hole 76 is provided on the outer wall of the strip shell 75.

[0045] The drive unit drives the cleaning roller 7 to rotate, and the gear 81 meshes with it to make each set of cleaning rollers 7 rotate in opposite directions. The zongzi leaves are transported to the cleaning roller 7. The zongzi leaves are transported forward in sequence by the rotation and squeezing of the upper and lower cleaning rollers 7. During the transport of zongzi leaves, water is supplied to each roller 71 through the water pump assembly. The water enters the liquid chamber through the port 72. The liquid chamber is filled with cleaning water, which causes the rubber layer 73 to expand. The sponge layer 74 squeezes and contacts the zongzi leaves. The water in the liquid chamber squeezes the valve ball 77 to overcome the elastic force and move, so that the valve hole 78 is opened. The water enters the strip shell 75 through the valve hole 78, and then enters the sponge layer 74 through the through hole 76. When the sponge layer 74 squeezes the zongzi leaves, it squeezes the water onto the surface of the zongzi leaves, so as to achieve simultaneous cleaning of the upper and lower surfaces of the zongzi leaves. The cleaning water leaks into the return water pool 6, is treated and recycled, and the cleaned zongzi leaves are sent to the receiving box 5.

[0046] like Figure 4 As shown, the water pump assembly includes a water pump body 9, which is installed on the side of the return water tank 6. The output shaft of the water pump body 9 is connected to one of the cleaning rollers 7 via a belt drive. The water outlet end of the water pump body 9 is connected to a connecting pipe 91. The end of the roller 71 is rotatably connected to the connecting pipe 91. The water inlet end of the water pump body 9 is connected to a water source.

[0047] During the process of the cleaning roller 7 rotating and transferring the zongzi leaves, the water pump body 9 is driven to draw water, and the water enters the inside of the roller 71 through the connecting pipe 91, so that the transfer and cleaning of the zongzi leaves are carried out simultaneously.

[0048] like Figure 3As shown, the drive device includes a motor 8, which is installed on the side of the return water tank 6. The output shaft of the motor 8 and the end of the cleaning roller 7 are both fixedly mounted with sprockets 82. The sprockets 82 are connected by chain drive. The diameter of the sprockets 82 at the end of the cleaning roller 7 in the direction from the receiving box 5 to the conveyor belt 2 gradually increases.

[0049] Motor 8 drives sprocket 82 via chain to rotate cleaning roller 7. Due to the difference in diameter of sprocket 82, the rotation speed of cleaning roller 7 gradually increases as it moves away from conveyor belt 2. When the zongzi leaf is delivered from conveyor belt 2 to the cleaning roller 7, the front cleaning roller 7 holds and transmits the zongzi leaf at a slower speed. The part of the zongzi leaf that passes the front cleaning roller 7 gradually contacts the rear cleaning roller 7. The rotation speed of the rear cleaning roller 7 increases, making the rotation speed of the rear cleaning roller 7 greater than the transmission speed of the zongzi leaf. This causes the cleaning roller 7 to "slip" with the surface of the zongzi leaf, which is used to rub and clean the debris on the surface of the zongzi leaf, thus achieving deep cleaning of the zongzi leaf.
