Description

Technical Field

[0001] The utility model belongs to the field of chrysanthemum packaging, in particular to a bag feeding device for a chrysanthemum packaging machine. Background Art

[0002] To extend the shelf life and freshness of small, liquid solid particles like chrysanthemums, facilitate storage, and better meet the needs and usage of different consumers, chrysanthemums are packaged in small bags. The chrysanthemums are typically packaged in small portions. The process typically involves weighing the chrysanthemums, placing them into a film inner bag, and then placing the filled inner bag into an outer bag.

[0003] When packaging chrysanthemums, a bag feeding mechanism is used to feed the bags one by one in an orderly manner to the packaging machine. However, existing bag feeding mechanisms generally use suction cups to absorb the bags. While suction cups can achieve this function, when the suction cups absorb the top bag of a stack, the bags below it are prone to shifting, affecting the quality of subsequent bag feeding. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a bag feeding device for a chrysanthemum packaging machine, aiming to solve the problem of poor bag feeding quality in the entire bag feeding process of the existing bag feeding device.

[0016] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0018] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0019] Combine Figure 1-4 As shown, the bag feeding device includes a machine 1, which is provided with a pair of side panels 2, a carrier plate 3 is provided between the side panels, and a baffle 4 is provided between the side panels 3 and tilted backward. A bag dividing mechanism and a bag feeding mechanism are respectively provided on the carrier plate 3 in front and behind the baffle 4. The bag dividing mechanism includes a pair of roller rods 5 and a main shaft rod 6 rotatably installed between the two side panels 2 and arranged in front and behind. A conveying wheel group 7 and a driving wheel 8 are respectively provided on the roller rod 5 and the main shaft rod 6. Each groove wheel in the conveying wheel group 7 on the carrier plate 3 is provided with a matching notch 9. A linkage belt 10 is provided between the two conveying wheel groups 7. A matching belt 11 is provided between the driving wheel 8 and the adjacent conveying wheel group. A avoidance groove 12 is provided on the carrier plate 3 corresponding to the belt 11. The machine 1 is also provided with a driving mechanism for driving the main shaft rod 6 to rotate.

[0020] After being processed in the factory, in order to extend the shelf life and freshness of liquid solid small particle materials such as chrysanthemums, facilitate storage and better adapt to the needs and use of consumers at different levels, after a series of processing, the chrysanthemums will be sealed in packaging bags using a packaging machine.

[0021] Before the packaging machine seals and packages the chrysanthemums, the bag feeding device can be used to send the packaging bags to the packaging machine one by one and in an orderly manner, and the packaging machine can be used to put the chrysanthemums into the packaging bags and seal them.

[0022] In this structure, a pair of limiting plates 13 and a pair of guide plates 14 are respectively installed on the carrier plate 3, located in front and behind the baffle 4. The limiting plates are higher than the guide plates. These two limiting plates form the bag placement area. When feeding bags, the stacked bags must first be placed in the bag placement area as required. Then, the bags are transported backwards by the bag-splitting mechanism. However, due to the blocking and limiting effects of the baffles, only the bottom-most bag can pass through the baffles and is then transported backwards by the bag-feeding mechanism. Once in place, the bag is gripped by the gripping mechanism on the packaging machine.

[0023] In this structure, the stacked packaging bags are placed in the bag placement area as required, and the packaging bags at the bottom layer are in contact with the conveyor wheel group and the belt respectively. When the main shaft rotates under the action of the driving mechanism, the driving wheel rotates, and under the synchronous linkage of the belt and the linkage belt, all the conveyor wheel groups rotate synchronously. At this time, the stacked packaging bags are conveyed backward as a whole under the joint transportation of the conveyor wheel group and the belt. However, under the obstruction of the baffle and the transportation of the belt, only the packaging bags at the bottom layer can pass through the gap between the baffle and the carrier, thereby achieving the effect of bagging the packaging bags one by one and in an orderly manner. After the packaging bags pass through the gap, and under the transportation of the bag feeding mechanism, the packaging bags move toward the rear of the carrier, waiting to be clamped by the clamping mechanism. The clamping mechanism is not the focus of this device, so it will not be emphasized here.

[0024] As a preferred structure, a notch 15 is provided on the side panel 2, and the bag feeding mechanism includes a slider 16 slidably installed in the notch 15, and a bag feeding rod 17 is rotatably provided between the two sliders 16. A bag feeding wheel 18 is provided in the middle of the bag feeding rod 17, and the bag feeding wheel 18 is located directly above the driving wheel 8. A connecting rod 19 is provided on one side panel 2 facing the bag feeding wheel 18, and a curved piece 20 is provided forward on the connecting rod 19, and the bag feeding wheel 18 is located in the curved piece 20. A pressure wheel 21 is rotatably provided on the curved piece 20, and a short rod 22 is screwed into the top of the side panel 2, and the bottom of the short rod 22 is connected to the slider 16, and a spring 23 is provided on the short rod 22 located in the notch 15.

[0025] After the current bag on the bottom layer passes through the gap between the baffle and the carrier plate, it is transported backward toward the carrier plate by the bag feeding mechanism. Specifically, after the front end of the bag passes through the gap, it is conveyed by the belt, sequentially passing over the pressure roller and the bag feeding wheel. Simultaneously, these rollers rotate and transport the current bag backward. During this process, the pressure roller acts as a guide, facilitating the bag's insertion between the belt and the bag feeding wheel. This ensures greater stability and smoother bag feeding throughout the entire bag feeding process.

[0026] As the front end of the current bag passes between the belt and the bag feeding wheel, the feeding wheel moves upward a short distance during this process. Simultaneously, the two sliders slide upward in the gap, compressing the spring. Under the preload of the spring, the bag is more stable throughout the feeding process, further improving the bag feeding effect.

[0027] In this structure, if Figure 1-3 A pair of conveying shafts 24 are rotatably provided on the side plate 2 behind the bag feeding wheel 18, wherein the lower conveying shaft is rotatable. A conveying wheel 25 is provided on the conveying shaft 24, and the two conveying shafts 24 are located above and below the carrier plate, wherein the lower conveying wheel 25 is located in the avoidance opening 12.

[0028] In actual situations, when the packaging bag is conveyed by the bag feeding mechanism, the front end of the packaging bag passes between the upper and lower conveying wheels. When the packaging bag is fed, the lower conveying shaft rotates and further drives the packaging bag to move backward.

[0029] Further as a priority structure, such as Figure 4 A double-layer pulley 26 is rotatably provided on the side plate 2, and the driving mechanism includes a driving motor 27 mounted on the side plate. The driving shaft of the driving motor 27 is provided with a power pulley 28, and the end of the main shaft rod 6 and the end of the lower transmission shaft 24 are respectively provided with a front pulley 29 and a rear pulley 30. The power pulley 28 and one of the pulleys of the double-layer pulley 26 are covered with a main belt 31, and a matching secondary belt 32 is covered between the other pulley, the front pulley 29, and the rear pulley 30.

[0030] In this structure, the drive mechanism primarily drives the main shaft and lower conveyor shaft. When the main shaft rotates, the drive pulley rotates synchronously, and the conveyor pulley assembly rotates in conjunction with the belt. Specifically, the drive motor drives the power pulley, which, in conjunction with the primary belt, rotates the double-layer pulley. Simultaneously, the secondary belt drives the front and rear pulleys, which rotate synchronously. This causes the main shaft and lower conveyor shaft to rotate, thereby feeding the packaging bags.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
