Description

Technical Field

[0001] This utility model belongs to the field of chrysanthemum packaging, and in particular relates to a bag feeding device for a chrysanthemum packaging machine. Background Technology

[0002] To extend the shelf life and freshness of free-flowing solid granular materials such as chrysanthemums, facilitate storage, and better meet the needs and uses of different consumers, chrysanthemums on the market are often packaged in small bags. The general procedure involves first weighing the chrysanthemums, then placing the weighed chrysanthemums into an inner film bag, and finally placing the inner bag into an outer bag to complete the packaging.

[0003] When packaging chrysanthemums, a bag-feeding device is used to feed the bags one by one and in an orderly manner towards the packaging machine. However, existing bag-feeding devices generally use suction cups to adhere the bags, which can achieve the purpose of feeding the bags. However, when the suction cup is adhering to the top stack of bags, the bags below are prone to shifting, affecting the overall quality of bag feeding. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a bag feeding device for a chrysanthemum packaging machine, which aims to solve the problem of instability of the existing bag feeding device for chrysanthemum packaging machines when feeding the packaging bags.

[0005] The present invention adopts the following technical solution:

[0006] The bag feeding device includes a machine base with a pair of side plates on the front side. A slide is provided between the side plates, and a pair of left and right baffles are provided on the slide. Three bag-separating assemblies are provided on the slide between the baffles. Each bag-separating assembly includes a bag-separating seat. An L-shaped pressure strip is provided on the front side of the bag-separating seat, and an inner baffle is provided on the rear side. A connecting rod is inserted into the bag-separating seat. A threaded hole is opened at the top of the connecting rod, and a base is provided at the bottom. A bag-separating wheel is rotatably provided in the base. A spring is provided on the connecting rod between the base and the bag-separating seat. A limit nut is screwed into the threaded hole. A cover is provided on the top of the bag-separating seat, and the limit nut is located inside the cover. Multiple rotatable conveyor belts are provided on the machine base.

[0007] Furthermore, a lead screw is rotatably provided between the two side plates and the middle bag-separating seat. A threaded sleeve is provided at the front end of the baffle, and a screw sleeve is provided in the left and right bag-separating seats. The threaded sleeve and the screw sleeve are located on the lead screw on the same side, and a rotating handle is provided at the end of the lead screw.

[0008] Furthermore, a shallow groove is provided on the front side of the bag holder, and a locking hole is provided in the shallow groove. An oblong groove is provided above the pressure strip, and a locking nut is inserted into the oblong groove and screwed into the locking hole.

[0009] Furthermore, the machine base is provided with a pair of rotating rods, one in front and one behind, and multiple conveyor belts are fitted between the two rotating rods.

[0016] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model 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 of the present utility model and are not intended to limit the scope of the present utility model.

[0017] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0018] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0019] Combination Figure 1-4 As shown, the bag feeding device includes a machine base 1. A pair of side plates 2 are formed on the front side of the machine base 1. A slide 3 is provided between the side plates 2. A pair of left and right baffles 4 are provided on the slide 3. Three bag-separating assemblies are provided on the slide 3 between the baffles 4. Each bag-separating assembly includes a bag-separating seat 5. An L-shaped pressure strip 6 is provided on the front side of the bag-separating seat 5, and an inner baffle 7 is provided on the rear side. A connecting rod 8 is inserted into the bag-separating seat 5. A threaded hole is opened at the top of the connecting rod 8, and a base 9 is provided at the bottom. A bag-separating wheel 10 is rotatably installed in the base 9. The bottom of the bag-separating wheel is exposed above the base. A spring 11 is provided on the connecting rod 8 between the base 9 and the bag-separating seat 10. A limit nut 12 is screwed into the threaded hole. A cover 13 is provided on the top of the bag-separating seat 5. The limit nut 12 is located inside the cover 13. Multiple rotatable conveyor belts 14 are provided on the machine base 1.

[0020] After being processed in the factory, chrysanthemums are packaged in sealed bags using packaging machines to extend their shelf life and freshness, facilitate storage, and better meet the needs and uses of consumers at different levels.

[0021] Before packaging chrysanthemums in small quantities, the chrysanthemum packaging machine needs to use a bag feeding device to send the packaging bags one by one in an orderly manner. Then the packaging machine will pack the chrysanthemums into the packaging bags in a fixed quantity and seal them.

[0022] In this structure, such as Figure 2 The inner side of the side plate 2 is provided with a guide post 15, and the bottom of the guide post 15 forms a chamfer 16. Since the bag feeding device includes a machine base with a pair of side plates, a slide is provided between the side plates, and a pair of left and right baffles are respectively provided on the slide, along with three bag-separating assemblies, and the bag-separating assembly includes a bag-separating seat, with a pressure strip on the front and an inner baffle strip on the rear. Therefore, the baffles and the inner baffle strip constitute the bag-feeding area. Before feeding bags to the packaging machine using this device, stacked packaging bags must first be placed in the bag-feeding area as required, and the packaging bags must fall onto the conveyor belt.

[0023] When the bag is fed, the conveyor belt starts to rotate, and the stack of packaging bags tends to move forward. However, due to the obstruction and limitation of the inner baffle and guide post, and the guiding effect of the guide angle, only the current packaging bag at the bottom can move forward under the drive of the conveyor belt. That is, the front end of the current packaging bag passes through the gap between the conveyor belt and the bag separating wheel. Under the pre-compression of the spring, the bag separating wheel can always press the current packaging bag tightly. At the same time, under the conveyor belt, the current packaging bag can move forward stably and be sent to the next station. At that time, the next packaging bag also moves to the next station under the action of the bag separating wheel.

[0024] In this structure, such as Figure 3 The bag-separating seat 5 has a shallow groove 17 on its front side, and a locking hole 18 is formed in the shallow groove 17. A cylindrical groove 19 is formed above the pressure strip 6, and a locking nut (not shown in the figure) passes through the cylindrical groove 19 and is screwed into the locking hole 18. During the orderly feeding of stacked packaging bags, the pressure strip acts as a vertical limiter, preventing the bags from bouncing during feeding and ensuring they are stably delivered to the next station. Furthermore, the installation height of the pressure strip is fine-tunable. To adjust the installation height, simply loosen the locking nut, move the pressure strip slightly up and down to determine its position, and then tighten the locking nut.

[0025] As a preferred structure, such as Figure 1 A lead screw 20 is rotatably provided between the two side plates 2 and the middle bag seat 5. A threaded sleeve 21 is provided at the front end of the baffle 4. A screw sleeve (covered in the figure) is provided in the left and right bag seats 5. The threaded sleeve 21 and the screw sleeve are located on the lead screw 20 on the same side. A rotating handle 22 is provided at the end of the lead screw 20.

[0026] In this structure, the left and right side plates are rotatably connected to the central bag-separating seat by lead screws, and the ends of the lead screws are equipped with rotating heads. The remaining two left and right bag-separating seats and the left and right baffles are respectively installed on the lead screws on the same side via threaded sleeves and threaded sleeves. Therefore, in actual practice, the position of the baffles can be adjusted by rotating the rotating heads. During the adjustment of the baffles, the size of the bag-feeding area changes accordingly to accommodate packaging bags of different sizes. During the above adjustment of the baffles, the bag-separating seats on the same side move together, adjusting their positions synchronously.

[0027] When adjusting the position of the baffle, simply rotate the rotary head. The rotary head drives the corresponding lead screw to rotate. During the rotation of the lead screw, the baffle and the bag-separating seat on it move along the length of the lead screw through the thread sleeve and the screw sleeve, respectively, until the position of the baffle is determined, and then stop rotating the rotary head.

[0028] As a specific structure, such as Figure 2 The machine base 1 is provided with a pair of rotating rods 23, and multiple conveyor belts 14 are sleeved between the two rotating rods 23. The rear rotating rod is provided with a driven wheel 24. The machine base 1 is provided with a drive motor 25. The drive shaft of the drive motor 25 is provided with a drive wheel 26. A drive belt is sleeved between the drive wheel 26 and the driven wheel 24.

[0029] In this device, when the conveyor belt is used for conveying, the drive motor starts to work, and the drive motor drives the drive wheel to rotate. Under the linkage of the drive belt, the driven wheel drives the rear rotating rod to rotate, and the conveyor belt rotates accordingly.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
