Description

Technical Field

[0002] Tableware refers to non-edible tools that come into direct contact with food during meals, and is used to assist in distributing or taking food. At present, there are many disposable tableware on the market, including chopsticks, straws, knives and forks, spoons, etc. In order to facilitate users, many suppliers package the three frequently used tableware in a plastic bag. In the prior art, the loading and packaging devices are mostly operated by operators to manually place different tableware in the package in sequence when loading disposable tableware. This method is not only inefficient, but also has high operation repetitiveness, and is prone to physical strain after long-term operation; at the same time, the environment of the disposable tableware loading and packaging equipment is relatively simple, and the protection for the operator's body is low. After long-term labor, the operator may use his hands to soothe the sore parts due to muscle soreness in the body, thereby transferring bacteria on the surface of the body to the surface of the disposable tableware, resulting in a decrease in the quality of the disposable tableware packaging, affecting the product quality.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] An automatic feeding and packaging device for disposable tableware sets, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, it includes a body 1; a loading mechanism 3 is movably connected to the top of the body 1, and the loading mechanism 3 can load disposable tableware, thereby loading a single or multiple disposable tableware into the packaging material, which is convenient for subsequent packaging operations.

[0038] Specifically, the feeding mechanism 3 includes a chopstick feeding assembly 31 and a spoon feeding assembly 32, which are symmetrically arranged on both sides of the machine body 1. The chopstick feeding assembly 31 and the spoon feeding assembly 32 are both movably connected to both sides of the machine body 1, and can be easily replaced or increased or decreased to adapt to the packaging operation of different numbers of disposable tableware. At the same time, the spoon feeding assembly 32 can not only feed disposable spoons, but also feed tableware with similar shapes.

[0039] It is worth noting that the chopstick feeding assembly 31 includes a shell 3101, which is movably connected to the body 1, and a feeding wheel 3102 is rotatably connected to the inner side of the shell 3101. A quantitative groove 3103 is provided on the side of the feeding wheel 3102. The feeding wheel 3102 can feed the disposable chopsticks, and the quantitative groove 3103 can separate the single and double chopsticks from the chopstick pile, so as to realize the feeding operation of the disposable chopsticks one by one. At the same time, the width of the quantitative groove 3103 is between a single chopstick and two chopsticks, so as to avoid multiple pairs of chopsticks from being moved to the quantitative groove 3103 at the same time. A storage plate 3104 is fixedly connected to the inside of the shell 3101, and the end of the storage plate 3104 corresponds to the position of the feeding wheel 3102. The structure of the storage plate 3104 can temporarily store the chopstick pile, and the storage plate 3104 whose end corresponds to the position of the feeding wheel 3102 can conveniently move the chopsticks to the inside of the quantitative groove 3103. A transmission wheel 3105 is rotatably connected to the outer side of the shell 3101 . The transmission wheel 3105 is fixedly connected to the loading wheel 3102 . The transmission wheel 3105 structure can drive the loading wheel 3102 .

[0040] Furthermore, the spoon feeding assembly 32 includes a storage seat 3201, which is movably connected to the body 1. The storage seat 3201 structure can temporarily store the spoon pile to facilitate subsequent feeding operations. The storage seat 3201 is fixedly connected to the side of the storage seat 3201. The support seat 3202 is provided with a slide groove 3203 on the inner side of the support seat 3202. The slide groove 3203 is an L-shaped structure. At the same time, there is a height difference between the two ends of the slide groove 3203 to form a one-way locking structure, so that the slide rod 3204 can only slide in one direction inside the slide groove 3203. The slide groove 3203 is slidably connected to the slide rod 3204, and the slide rod 3204 is a cylindrical structure, so as to reduce the friction when sliding inside the slide groove 3203. Two connecting rods 3205 are rotatably connected to the slide bar 3204, and the ends of the two connecting rods 3205 are rotatably connected to the piston cylinder 3206 and the piston rod 3207 respectively. The piston cylinder 3206 is sleeved on the outside of the piston rod 3207. The piston rod 3207 is a hollow structure. The piston rod 3207 can form an adsorption structure through the tubular end to adsorb the disposable spoon to be loaded, and the connecting rod 3205 structure can drive the piston cylinder 3206 and the piston rod 3207 to move synchronously. The connecting rod 3205 structure has the same length. At the same time, the connecting rod 3205, the piston cylinder 3206, the piston rod 3207 and the slide bar 3204 form an isosceles trapezoidal structure. When the slide bar 3204 approaches the piston cylinder 3206, the piston cylinder 3206 and the piston rod 3207 can be moved in the opposite direction, so that a negative pressure environment is formed inside the piston cylinder 3206, which is convenient for adsorption of the disposable spoon.

[0041] In addition, a suction cup 3208 is fixedly connected to the end of the piston rod 3207, and the suction cup 3208 is interconnected with the inside of the piston cylinder 3206 through the piston rod 3207. The suction cup 3208 structure can increase the adsorption area with the disposable spoon, thereby improving the adsorption effect when the disposable spoon is adsorbed by the negative pressure piston cylinder 3206. A stopper 3 is fixedly connected to the inner side of the support seat 3202, and the position of the stopper 3 corresponds to that of the piston cylinder 3206 and the piston rod 3207. The stopper 3 can block the piston cylinder 3206 and the piston rod 3207, so that the slide rod 3204 can approach or move away from the piston cylinder 3206 and the piston rod 3207 when driven, and the slide rod 3204 drives the piston cylinder 3206 and the piston rod 3207 through the connecting rod 3205.

[0042] On this basis, a moving block 3210 is slidably connected to the other side of the slide bar 3204, and a buffer spring 1 3211 is fixedly connected to the inner side of the moving block 3210. The moving block 3210 and the buffer spring 1 3211 can cooperate with the slide slot 3203. When the moving block 3210 moves from a high position inside the slide slot 3203 to a low position, it can be elastically ejected outward, thereby limiting the moving direction of the slide bar 3204. A limit block 3213 is connected to the inner side of the moving block 3210. The limit block 3213 is slidably connected to the inside of the slide bar 3204. The position of the limit block 3213 corresponds to that of the connecting rod 3205. The limit block 3213 structure can move with the moving block 3210. When the moving block 3210 is ejected outward, it can drive the limit block 3213 to move, thereby locking the connecting rod 3205.

[0043] It is worth mentioning that the support seat 3202 is rotatably connected to a driving wheel 3214 on the side, and the driving wheel 3214 is rotatably connected to a crank 3215 on the side. The end of the crank 3215 is rotatably connected to a driving block 3216. The inner side of the driving block 3216 is rotatably connected to the sliding bar 3204 through a connecting rod. The driving wheel 3214 structure can move the driving block 3216 through the crank 3215, so that the driving block 3216 can swing back and forth in the horizontal direction, thereby using the driving block 3216 to reciprocate and drive the sliding bar 3204. At the same time, the driving block 3216 is connected to the sliding bar 3204 through the connecting rod, so that the driving block 3216 can drive the sliding bar 3204 to move in the vertical direction through the connecting rod when moving horizontally.

[0044] Example 2

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, on the basis of Example 1, a conveying mechanism 2 is provided at the top of the body 1, and the conveying mechanism 2 can convey the packaging bags and disposable tableware, thereby facilitating the loading of different tableware and the subsequent packaging operations.

[0046] In this embodiment, the conveying mechanism 2 includes a conveying chain 201, which is rotatably connected to the machine body 1, and a conveying block 202 is fixedly connected to the conveying chain 201. The conveying chain 201 can provide driving force for the conveying block 202, so that the conveying block 202 can move at the top of the machine body 1 and perform a conveying operation on the disposable tableware. A double-axis motor 203 is fixedly connected inside the machine body 1, and a driving sprocket 204 is fixedly connected to the end of the output shaft of one end of the double-axis motor 203. The double-axis motor 203 can drive the conveying chain 201 through the driving sprocket 204, and the driving sprocket 204 is in an incomplete state, and one side of the driving sprocket 204 is in a smooth state. A guide sprocket 205 is rotatably connected inside the machine body 1, and the driving sprocket 204 and the guide sprocket 205 are both meshed with the conveying chain 201. The guide sprocket 205 can support and guide the two ends of the conveying chain 201, so that the conveying chain 201 remains stable during the movement. At the same time, the two sides of the bottom of the conveyor chain 201 are limited by the machine body 1, so as to keep the bottom of the conveyor chain 201 in a horizontal state.

[0047] On this basis, the conveying mechanism 2 also includes a linkage sprocket 206 rotatably connected to the inner side of the machine body 1, the linkage sprocket 206 is meshed with the conveying chain 201, and the linkage sprocket 206 can be rotated by the transmission of the conveying chain 201. The outer side of the linkage sprocket 206 is connected with a linkage gear set 207, and the linkage gear set 207 is two mutually perpendicular meshing bevel gears to convert the driving direction. The outer side of the linkage gear set 207 is fixedly connected with a support rod 208, and the outer side of the support rod 208 is sleeved with a transmission belt. The support rod 208 structure can support the two bevel gears in the linkage gear set 207 respectively, and the support rod 208 can transmit the driving force through the transmission belt. At the same time, there is at least one linkage gear set 207, so the transmission belt can be connected to the outer side of the transmission wheel 3105 or the driving wheel 3214 respectively, and the conveying chain 201 is used to drive the chopstick feeding assembly 31 and the spoon feeding assembly 32 to run synchronously.

[0048] Example 3

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.11 As shown, on the basis of Embodiment 2, a packaging mechanism 4 is provided at one end of the machine body 1, and the packaging mechanism 4 can perform packaging operations on disposable tableware.

[0050] In this embodiment, the packaging mechanism 4 includes a packaging frame 401, which is fixedly connected to the top of the body 1. The packaging frame 401 is a U-shaped structure, which can support the entire packaging mechanism 4. At the same time, the conveying chain 201 passes through the bottom of the packaging frame 401, so that the disposable tableware can be moved to the inside of the packaging frame 401 for convenient packaging operations. The inner side of the packaging frame 401 is rotatably connected with a heat sealing wheel 402, and the top of the heat sealing wheel 402 is fixedly connected with a heat conducting rod 403, which passes through the packaging frame 401. The outer side of the heat conducting rod 403 is provided with an induction heating coil 404, and the heat sealing wheel 402 can rotate and perform heat sealing operations on the back of the disposable tableware packaging. The heat conducting rod 403 structure can transfer heat to the heat sealing wheel 402, so that the heat sealing wheel 402 is in a high temperature state to melt the plastic film to achieve the packaging effect, and the induction heating coil 404 structure can heat the heat conducting rod 403 without affecting the rotation of the heat conducting rod 403. A transmission rod 405 is rotatably connected to the packaging frame 401, and a guide wheel 406 is fixedly connected to the end of the transmission rod 405. The guide wheel 406 structure can move and guide the package whose back is packaged. A transmission gear 407 is fixedly connected to the top of the transmission rod 405. The two transmission gears 407 are meshed with each other. The meshed transmission gears 407 can make the two guide wheels 406 rotate in opposite directions, thereby realizing the traction function of the packaging bag. A transmission sprocket 408 is fixedly connected to the outer side of the transmission rod 405 and the top of the heat conducting rod 403. A transmission chain 409 is sleeved on the outer side of the transmission sprocket 408. The transmission chain 409 can enable the transmission rod 405 to transmit the heat conducting rod 403.

[0051] It is worth noting that a mobile frame 410 is slidably connected to the packaging frame 401, and two heat-sealing blocks 411 are connected to the end of the mobile frame 410 through a buffer spring 2. The mobile frame 410 structure can slide on the packaging frame 401 and drive the heat-sealing blocks 411 to move synchronously, and the heat-sealing blocks 411 can perform heat-sealing operations on the end of the package to seal the packaging bag. A cutting knife 412 is connected between the two heat-sealing blocks 411, and the cutting knife 412 structure can cut the heat-sealed package and divide the package of disposable tableware into independent packages. A contact spring 413 is fixedly connected to the side of the mobile frame 410 and the inner side of the packaging frame 401. The contact spring 413 structure can communicate with the heat-sealing block 411, so that the heat-sealing block 411 is automatically heated after moving to the set position, thereby realizing the heat-sealing operation on the package. A rack is fixedly connected to the side of the mobile frame 410, and a driving gear 414 is fixedly connected to the output shaft at the other end of the dual-axis motor 203. The driving gear 414 meshes with the rack. The driving gear 414 is a residual gear structure. The driving gear 414 can drive the mobile frame 410 through the rack to make the mobile frame 410 move up and down. The driving gear 414 can cooperate with the driving sprocket 204 to achieve alternating conveying and heat sealing operations. A reset spring 415 is sleeved on the top end of the outer side of the mobile frame 410. The reset spring 415 structure can automatically reset the mobile frame 410 so that the heat sealing block 411 can automatically move away from the package after the heat sealing is completed.

[0052] When the automatic feeding and packaging device for a disposable tableware set of the present invention is used, the dual-axis motor 203 is started, and the dual-axis motor 203 then drives the conveying chain 201 to move through the driving sprocket 204, and the conveying chain 201 then drives the conveying block 202 to move synchronously, and the conveying block 202 then drives the package to move. While the conveying chain 201 is moving, the linkage sprocket 206 rotates synchronously under the drive of the conveying chain 201, and the linkage sprocket 206 drives the support rod 208 to rotate through the linkage gear set 207. When the disposable chopsticks are fed, the rotating support rod 208 drives the transmission wheel 3105 to rotate through the transmission belt, and the feeding wheel 3102 rotates synchronously therewith, and the feeding wheel 3102 feeds the disposable chopsticks through the quantitative groove 3103 during the rotation process. After the conveyor chain 201 moves a set length, the loading wheel 3102 rotates a specific angle, so that the subsequent quantitative slot 3103 rotates to the loaded quantitative slot 3103, so that the disposable chopsticks loaded onto the package maintain the same interval, which is convenient for subsequent packaging operations. When loading the disposable spoon, the rotating support rod 208 drives the driving wheel 3214 to rotate through the transmission belt, and the driving wheel 3214 drives the driving block 3216 to reciprocate through the crank 3215 during the rotation process. When the driving block 3216 moves, it drives the sliding bar 3204 to move synchronously through the connecting rod. When the sliding bar 3204 moves from moving away from the disposable spoon to moving closer to the disposable spoon, the sliding bar 3204 drives the piston cylinder 3206 and the piston rod 3207 to move synchronously through the connecting rod 3205. When the piston cylinder 3206 and the piston rod 3207 move to the stopper 3, the stopper 3 restricts the movement of the piston cylinder 3206 and the piston rod 3207. At the same time, the sliding bar 3204 moves along the slide groove 3203 from the high position to the low position of the support seat 3202, and drives the piston cylinder 3206 and the piston rod 3207 to move downward until the suction cup 3208 at the bottom of the piston rod 3207 moves to the top of the disposable spoon. The sliding bar 3204 continues to move until the sliding bar 3204 moves to the bottom of the slide groove 3203. As the slide bar 3204 moves, the movement of the piston cylinder 3206 and the piston rod 3207 is limited by the block 3, so the slide bar 3204 continues to approach the piston cylinder 3206 and the piston rod 3207 during the movement, and the connecting rod 3205 drives the piston cylinder 3206 and the piston rod 3207 to move away from each other, and after the suction cup 3208 contacts the disposable spoon, a low pressure state is formed inside the piston cylinder 3206, and the disposable spoon is sucked by the suction cup 3208. When the slide bar 3204 moves to the bottom of the slide groove 3203, the slide bar 3204 moves from the high position of the slide groove 3203 to the low position of the slide groove 3203, and the height difference here can limit the movement of the slide bar 3204 to prevent the slide bar 3204 from moving in the opposite direction.At the same time, the moving block 3210 inside the chute 3203 pops outward under the action of the buffer spring 1 3211 and drives the limit block 3213 to move synchronously, thereby locking the connecting rod 3205. At this time, the driving block 3216 moves to the end under the drive of the crank 3215, and then the driving block 3216 moves in the opposite direction, while the reverse movement of the slide bar 3204 is limited by the chute 3203. Therefore, the driving block 3216 drives the slide bar 3204 to move upward through the connecting rod, and the piston cylinder 3206 and the piston rod 3207 drive the disposable spoon to move upward synchronously, separating the disposable spoon from the spoon pile. When the slide bar 3204 moves to the top of the chute 3203, the movement of the slide bar 3204 is limited by the top of the chute 3203, and the slide bar 3204 moves along the chute 3203 toward the conveying block 202 under the drive of the driving block 3216. When the disposable spoon moves close to the conveying block 202, the interior of the chute 3203 gradually increases, and pushes the moving block 3210 into the slide bar 3204. When the limit block 3213 moves away from the connecting rod 3205, the piston cylinder 3206 and the piston rod 3207 approach each other under the action of the internal low pressure. When the internal pressure increases to close to the ambient pressure, the disposable spoon falls off the suction cup 3208 and falls onto the package. When the piston cylinder 3206 moves to the stopper 3 at the other end, the piston cylinder 3206 and the piston rod 3207 are restricted by the stopper 3 again. After the slide bar 3204 continues to move, the piston cylinder 3206 and the piston rod 3207 are close to each other and facilitate the subsequent adsorption operation of the disposable spoon. When the package containing the disposable chopsticks and the disposable spoon moves to the packaging mechanism 4, the packaging mechanism 4 immediately performs the packaging operation on the package. The support rod 208 drives the transmission rod 405 to rotate continuously through the transmission belt, and the transmission rod 405 drives the guide wheel 406 to rotate therewith, and the two guide wheels 406 rotate in the opposite direction under the drive of the transmission gear 407 and pull the package, so that the package side is closed and the disposable tableware is wrapped inside the package. During the rotation process, the transmission rod 405 drives the heat-conducting rod 403 to rotate continuously through the transmission sprocket 408 and the transmission chain 409, and the heat-sealing wheel 402 rotates synchronously therewith, and the induction heating coil 404 continuously heats the heating rod, and the heat-sealing wheel 402 performs heat-sealing operation on the closed package therewith. The driving sprocket 204 and the driving gear 414 are both 1 / 2 residual teeth, so the driving sprocket 204 and the driving gear 414 alternately drive the conveying chain 201 and the mobile frame 410 when driven by the dual-axis motor 203. After the mobile frame 410 is driven by the driving gear 414, the mobile frame 410 continues to descend until the heat-sealing block 411 moves to the packaging surface. The contact spring piece 413 on the side of the heat sealing block 411 then contacts the contact spring piece 413 on the inner side of the packaging frame 401, and the heat sealing block 411 then performs a heat sealing operation on the connection of the disposable tableware package.During the heat sealing process, the moving frame 410 continues to move downward, and the heat sealing block 411 moves toward the moving frame 410 and compresses the buffer spring. The cutting knife 412 inside the heat sealing block 411 moves out and cuts the package connection. During the downward movement of the moving frame 410, the return spring 415 continues to be compressed. When the driving gear 414 rotates to disengage from the rack, the moving frame 410 moves upward and resets under the elastic action of the return spring 415. Then the packaging operation of the single package of disposable tableware is completed.
