Description

Technical Field

[0001] The present invention relates to a chopstick packaging device, and more specifically to a chopstick inserting machine. Background Art

[0002] The packaging of chopsticks mainly adopts the insert packaging method, that is, inserting chopsticks into a paper card, using the deformation ability of the paper card itself to clamp the chopsticks in the paper card, and then packaging the inserted paper cards to effectively package the chopsticks, facilitating the transportation and sale of chopsticks. The earliest insert method was mainly to manually insert chopsticks into the paper card by humans, but the manual method is inefficient and prone to the problem of missed insertion.

[0003] Therefore, in the prior art, a chopstick inserting machine is provided, such as the invention patent "Automatic Chopstick Inserting Machine and Its Inserting Method" with the application number 201810147883.7, which discloses a method of combining a paper card feeding mechanism, a chopstick storage mechanism, a paper card forming mechanism, a paper card conveying mechanism, and a chopstick pushing mechanism to achieve automatic feeding of the paper card, then forming, and finally inserting the chopsticks into the paper card to achieve the effect of automatic insertion. The paper card feeding mechanism in this inserting machine mainly includes a paper storage slot and a grasping manipulator. The paper storage slot is arranged above the conveyor belt, and the grasping manipulator is arranged below the conveyor belt. Then, a plurality of carriers are arranged on the conveyor belt. When a carrier moves below the paper storage slot, the grasping manipulator passes through the carrier and rises to grasp the paper card in the paper storage slot, and then descends with the paper card. When the paper card contacts the carrier, the paper card is released to achieve the effect of pulling the paper card in the paper storage slot and placing it on the carrier. This method of feeding the paper card has high precision requirements for the grasping manipulator to place the paper card. For example, if the placement is too late, it is easy to occur that when the paper card has already reached the carrier, the grasping manipulator still grasps the paper card and descends, causing the paper card to deform. Moreover, the grasping manipulator is arranged below the conveyor belt, resulting in a large number of components below the conveyor belt, making it easy to get stuck during operation. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a chopstick inserting machine in which the paper card is not easily deformed and the components below the conveyor belt can be effectively reduced.

[0005] To achieve the above object, the present invention provides the following technical solution: A chopstick inserting machine, comprising a frame and a paper card feeding device, a chopstick feeding device and a paper card forming device which are all arranged on the frame. A conveyor belt is provided on the frame, and the paper card feeding device, the chopstick feeding device and the paper card forming device are sequentially distributed on the conveyor belt to automatically convey the paper card onto the conveyor belt, and after being conveyed to the paper card forming device by the conveyor belt for forming, the chopsticks are inserted into the paper card by the chopstick feeding device. The paper card feeding device includes a paper feeding rack, a paper storage groove and a paper rotating manipulator. The paper feeding rack is fixed at a position on the frame close to the end of the conveyor belt. The paper storage groove is installed on the upper side of the paper feeding rack to be above the conveyor belt. The paper rotating manipulator is installed on the paper feeding rack so as to be able to move up and down to grab the paper card in the paper storage groove and then turn it over and place it on the conveyor belt.

[0006] As a further improvement of the present invention, the paper rotating manipulator includes a sliding plate, a suction nozzle and a rotating shaft. A turning plate is fixedly connected to the paper feeding rack. The sliding plate is arranged on the turning plate so as to be able to slide up and down. The suction nozzle is fixed at one end of the rotating shaft and turns up and down as the rotating shaft rotates. The end of the rotating shaft facing away from the suction nozzle is rotatably inserted through the sliding plate. A turning groove extending from top to bottom is formed on the turning plate. A turning lever is fixed on the end of the rotating shaft facing away from the suction nozzle. One end of the turning lever is fixed on the side surface of the end of the rotating shaft, and the other end is provided with a rotatable runner. The runner is arranged in the turning groove to slide up and down in the turning groove. A turning notch is formed on the groove wall on one side of the turning groove. A reset lever is fixed at a position on the rotating shaft close to the turning lever. The end of the reset lever facing away from the rotating shaft is connected to the sliding plate through a spring to drive the rotation of the rotating shaft so that the turning lever rotates towards the groove wall on the side of the turning notch, driving the runner to roll along the groove wall of the turning groove.

[0007] As a further improvement of the present invention, the chopstick feeding device includes a chopstick storage box and a chopstick pushing mechanism arranged below the chopstick storage box. The lower end of the chopstick storage box is opened. The chopstick pushing mechanism includes a chopstick guiding plate and a chopstick pushing rod. The chopstick guiding plate is arranged below the chopstick storage box and is communicated with the inside of the chopstick storage box. A plurality of strip-shaped chopstick guiding chutes are arranged on the upper side surface of the chopstick guiding plate. One end of the chopstick guiding chute extends to be close to the conveyor belt relative to the paper card forming device. The chopstick pushing rod is slidably arranged in the chopstick guiding chute to push the chopsticks in the chopstick guiding chute into the paper card in the paper card forming device.

[0008] As a further improvement of the present invention, a shaking block capable of sliding left and right is arranged between the lower end of the chopstick storage box and the chopstick guiding plate. A through hole for the chopsticks to pass through is formed in the middle of the shaking block to shake the chopsticks in the through hole onto the chopstick guiding chute on the chopstick guiding plate.

[0009] As a further improvement of the present invention, the side of the shaking block facing the conveyor belt is open to form an opening. At a position near the lower end of the side surface of the chopstick storage box, there is a chopstick blocking plate that can slide up and down relative to the opening. The lower side edge of the chopstick blocking plate is placed on the notch of the chopstick guiding chute to form a passage that only allows a pair of chopsticks to pass through in combination with the chopstick guiding chute.

[0010] As a further improvement of the present invention, a rising push rod is fixed on the lower side surface of the side of the chopstick guiding plate close to the conveyor belt. There is a rising air cylinder at a position of the machine frame below the rising push rod. The pushing rod of the rising air cylinder is fixedly connected to the rising push rod to push the rising push rod up or down. When the chopstick pushing rod is about to push the chopsticks, the rising air cylinder drives the rising push rod to rise, causing the side of the chopstick guiding plate facing the conveyor belt to tilt up.

[0011] The beneficial effects of the present invention are as follows. By setting up the machine frame, paper card feeding device, chopstick feeding device, and paper card forming device, it can effectively form an effect of automatically conveying chopsticks and paper cards and then automatically inserting the chips. By setting the paper card feeding device in the form of a paper feeding rack, paper storage groove, and paper transferring manipulator combination, on the one hand, since the paper transferring manipulator places the paper card above the conveyor belt, there will be no problem of pulling the paper card due to slow release. On the other hand, all the overall components are set above the conveyor belt, so it will not cause the problem of complex structure below the conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will further elaborate on the present invention in conjunction with the embodiments given in the drawings.

[0017] Refer to Figures 1 to 4As shown in the figure, a chopstick inserting machine according to this embodiment includes a frame 1, a paper card feeding device 2, a chopstick feeding device 3, and a paper card forming device 4 all arranged on the frame 1. A conveyor belt 5 is provided on the frame 1. The paper card feeding device 2, the chopstick feeding device 3, and the paper card forming device 4 are sequentially distributed on the conveyor belt 5 to automatically convey the paper card onto the conveyor belt 5, and after being conveyed to the paper card forming device 4 for forming through the conveyor belt 5, the chopsticks are inserted into the paper card by the chopstick feeding device 3. The paper card feeding device 2 includes a paper feeding rack 21, a paper storage slot 22, and a paper turning manipulator 23. The paper feeding rack 21 is fixed at a position on the frame 1 close to the end of the conveyor belt 5. The paper storage slot 22 is installed on the upper side of the paper feeding rack 21 to be above the conveyor belt 5. The paper turning manipulator 23 is installed on the paper feeding rack 21 so as to be able to move up and down, and grabs the paper card in the paper storage slot 22 and then flips it and places it on the conveyor belt 5. Through the setting of the paper feeding rack 21, the paper storage slot 22 and the paper turning manipulator 23 can be arranged above the conveyor belt 5. Then, through the setting of the paper turning manipulator 23, the paper card in the paper storage slot 22 can be effectively grabbed and then flipped and placed on the conveyor belt 5. Thus, compared with the prior art in which the direct pulling method is adopted, the paper turning manipulator 23 can be arranged between the conveyor belt 5 and the paper storage slot 22, rather than being arranged below the conveyor belt 5. While avoiding the problem that the paper card is easily deformed due to pulling, it also avoids the problem that the structure below the conveyor belt 5 becomes complicated.

[0018] As a specific embodiment of the improvement, the paper transfer manipulator 23 includes a slide plate 231, a suction nozzle 232, and a rotating shaft 233. A steering plate 211 is fixedly connected to the paper feeding rack 21. The slide plate 231 is slidably arranged up and down on the steering plate 211. The suction nozzle 232 is fixed to one end of the rotating shaft 233 and turns up and down as the rotating shaft 233 rotates. The end of the rotating shaft 233 facing away from the suction nozzle 232 is rotatably inserted through the slide plate 231. A steering groove 2111 extending from top to bottom is formed in the steering plate 211. A steering lever 2321 is fixed to the end of the rotating shaft 233 facing away from the suction nozzle 232. One end of the steering lever 2321 is fixed to the side surface of the end of the rotating shaft 233, and the other end is provided with a rotatable runner 2322. The runner 2322 is arranged in the steering groove 2111 to slide up and down in the steering groove 2111. A steering notch 21111 is formed in one side wall of the steering groove 2111. A reset lever 3221 is fixed to the position of the rotating shaft 322 close to the steering lever 2321. The end of the reset lever 3221 facing away from the rotating shaft 322 is connected to the slide plate 231 through a spring, so as to drive the rotating shaft 322 to rotate, making the steering lever 2321 rotate towards the notch wall of the steering notch 21111, driving the runner 2322 to roll along the wall of the steering groove 2111. Through the cooperative setting of the slide plate 231 and the steering groove 2111 in the above structure, when the slide plate 231 descends, through the cooperative action of the steering notch 21111 and the steering lever 2321, when the slide plate 231 descends to the position of the steering notch 21111, the steering lever 2321 will drive the runner 2322 to be embedded into the steering notch 21111 under the action of the reset lever 3221 and the spring. At this time, the slide plate 231 continues to descend, and the runner 2322 will be stuck in the steering notch 21111. Therefore, the steering lever 2321 and the reset lever 3221 will overcome the pulling force of the spring and the whole will turn over. In this way, it is effectively realized that during the up and down movement of the slide plate 231, the rotating shaft 322 can drive the suction nozzle 232 to turn up and down. In this way, there is no need to additionally set a turning motor to drive the rotating shaft 322 to drive the suction nozzle 232 to turn, thus greatly simplifying the structure of the paper transfer manipulator 23.

[0019] As a specific implementation of the improvement, the chopstick feeding device 3 includes a chopstick storage box 31 and a chopstick pushing mechanism 32 arranged below the chopstick storage box 31. The lower end of the chopstick storage box 31 is open. The chopstick pushing mechanism 32 includes a chopstick guiding plate 321 and a chopstick pushing rod 322. The chopstick guiding plate 321 is arranged below the chopstick storage box 31 and is communicated with the inside of the chopstick storage box 31. A plurality of chopstick guiding chutes 3211 are arranged on the upper side surface of the chopstick guiding plate 321. One end of the chopstick guiding chute 3211 extends to be close to the conveyor belt 5 relative to the paper card forming device 4. The chopstick pushing rod 322 is slidably arranged in the chopstick guiding chute 3211 to push the chopsticks in the chopstick guiding chute 3211 into the paper card in the paper card forming device 4. Through the above structure, the chopsticks can be pushed into the paper card formed on the conveyor belt 5 by the chopstick pushing rod 322 through the chopstick guiding chute 3211 on the chopstick guiding plate 321, so as to automatically push the chopsticks into the paper card and complete the operation of inserting the chopsticks into the paper card.

[0020] As a specific implementation of the improvement, a shaking block 311 that can slide left and right is arranged between the lower end of the chopstick storage box 31 and the chopstick guiding plate 321. A through hole for the chopsticks to pass through is formed in the middle of the shaking block 311, so that the chopsticks in the through hole can shake into the chopstick guiding chute 3211 on the chopstick guiding plate 321. When the chopsticks are placed in the chopstick storage box 31, due to the large number of chopsticks, it is easy to accumulate. Therefore, through the shaking action of the shaking block 311, the accumulated chopsticks in the chopstick storage box 31 can be shaken and scattered, so that the chopsticks can slide better from the chopstick storage box 31 into the chopstick guiding chute 3211, greatly increasing the conveying efficiency of the chopsticks and reducing the risk of the chopsticks getting stuck.

[0021] As a specific implementation of the improvement, the side of the shaking block 311 facing the conveyor belt 5 is open to form an opening. A chopstick blocking plate 312 that can slide up and down is arranged on the side of the chopstick storage box 31 near the lower end relative to the opening. The lower side edge of the chopstick blocking plate 312 is placed on the notch of the chopstick guiding chute 3211 to form a channel that only allows a pair of chopsticks to pass through in combination with the chopstick guiding chute 3211. Through the setting of the chopstick blocking plate 312, when the chopstick pushing rod 322 pushes out the chopsticks, only a pair of chopsticks can be pushed out in one chopstick guiding chute 3211, and the problem of pushing multiple chopsticks will not occur. Moreover, by setting the blocking plate 312 to be slidable up and down, when the chopsticks in the chopstick storage box 31 are slightly deformed, the chopsticks can also be inserted into the paper card on the conveyor belt 5 by squeezing open the blocking plate 312, reducing the problem of chopsticks getting stuck during the conveying process of the chopsticks.

[0022] As a specific embodiment of the improvement, a rising push rod 323 is fixed on the lower side surface of the guide chopstick plate 321 close to the conveyor belt 5. An ascending cylinder 324 is provided at the position of the frame 1 relative to the lower side of the rising push rod 323. The push rod of the ascending cylinder 324 is fixedly connected to the rising push rod 323 to push the rising push rod 323 to rise or fall. When the chopstick pushing rod 322 is about to push the chopsticks, the ascending cylinder 324 drives the rising push rod 323 to rise, causing the side of the guide chopstick plate 321 facing the conveyor belt 5 to tilt up. In the prior art, in order to reduce the situation where the chopsticks abut against the hole wall of the insertion hole on the paper card during the insertion process, generally the method of inserting the tip of the chopsticks is adopted. Thus, through the combination of the rising push rod 323 and the ascending cylinder 324, it is possible to effectively lift the tip of the chopsticks when inserting the chopsticks, so that the tip is in a suspended state as much as possible. In this way, the probability of the end of the chopsticks abutting against the hole wall of the insertion hole on the paper card can be further reduced.

[0023] In summary, for the chopstick inserting machine of this embodiment, by using the paper transfer manipulator 23 as the main conveying component, the problems in the prior art such as the deformation of the paper card caused by releasing too late or the complication of the structure below the conveyor belt 5 can be avoided.

[0024] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
