Description

Technical Field

[0001] This utility model relates to the field of ton bag machine technology, and in particular to a bag opening machine that integrates large and small bags. Background Technology

[0002] A ton bag machine, also known as a bulk bag packaging machine or a large bag packaging machine, is an automated packaging equipment designed to handle large-capacity, bulk materials. Through integrated functions such as automatic feeding, weighing, filling, and sealing, it can efficiently and accurately pack powder, granules, or flakes into flexible container bags (commonly known as ton bags) with a typical capacity of 500 to 2000 kilograms.

[0003] During the unloading process of ton bags, dust suppression devices are needed to clean up the flying dust. For example, the prior art Chinese patent announcement number "CN106807628A" discloses a self-cleaning dry powder ton bag breaking machine, which includes a frame, a breaking component, a dust removal component, and a vibrating screening component. The breaking component includes a feeding platform panel and a reducer and a cutter shaft connected to the cutter disc motor. The cutter shaft is equipped with multiple cutter discs, and the upper part of all the cutter discs is inserted through the opening on the feeding platform panel and protrudes above the panel. The dust removal component includes an induced draft fan, a dust removal chamber, a row of suspended dust filter bags, and an air storage cylinder. The air storage cylinder is equipped with inlet and outlet control components. The steel pipe at the end of the outlet control component extends into the dust removal chamber and is equipped with a row of dust cleaning nozzles corresponding to the dust filter bags. The vibrating screen component includes a vibrating screen box, a slagging outlet, and a guide hopper. Two vibrating motors are fixed on the vibrating screen box. This invention adopts a forklift horizontal push-pack feeding process, with a compact overall structure and low height. It can not only effectively suppress dust overflow, but also has high bag breaking efficiency, simple operation, save manpower, and reduce the labor intensity of operators.

[0004] In practice, the dust filter bag is fixedly connected to the dust collection chamber. Although a dust cleaning nozzle is provided to clean the dust filter bag, it is not convenient to disassemble it when the dust filter bag ages and is damaged after long-term use, which may affect the subsequent processing efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology has the disadvantage that it is not convenient to disassemble the dust filter bag and the dust removal chamber, and to propose a bag opening machine that integrates large and small bags.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a bag opening machine that integrates large and small bags, including a support frame. Inside the support frame, a lifting component, a bag tapping component, and a bag opening tank are arranged in sequence. Inside and outside the bag opening tank, a dust suppression structure, a blowing component, and a negative pressure component are respectively installed. The dust suppression structure is detachably connected to the openable can via a fixing component.

[0007] Furthermore, the interior of the can has a feeding chamber and an installation chamber, the feeding chamber is connected to the installation chamber, and a partition and the dust suppression structure are fixedly connected in the installation chamber; The can is also fixedly connected to a sealing plate at the opening of the mounting cavity.

[0008] Furthermore, the working ends of both the blow-jet assembly and the negative pressure assembly extend into the mounting cavity.

[0009] Furthermore, the dust suppression structure includes an mounting plate and several filter cartridges, the filter cartridges being fixedly connected to the mounting plate, the mounting plate being erected on top of the partition, and the filter cartridges being connected to each other through a positioning structure.

[0010] Furthermore, the fixing component includes torsion bars, which are rotatably connected to both sides inside the mounting cavity. Each of the two torsion bars has a stop block fixedly connected to its outer wall. The torsion bars are rotated half a turn to drive the stop blocks to press against the side of the mounting plate.

[0011] Furthermore, it also includes a ratchet and two pawls, the ratchet being fixedly connected to the end of the torsion bar, and the two pawls being rotatably connected to the inner wall of the mounting cavity via a shaft and a torsion spring; The two pawls are disposed on both sides of the ratchet, and respectively lock the ratchet in the clockwise and counterclockwise directions; The end of the pawl extends outward to form a force-applying part.

[0012] The present invention proposes a bag opening machine that integrates large and small bags. The beneficial effects are as follows: The present invention has a dust suppression structure in the bag opening tank. The dust suppression structure, together with the negative pressure component, can suppress the flying dust by creating a negative pressure environment during the feeding process. After the negative pressure component stops working, the dust on the outside of the filter cartridge can be cleaned by the blowing component. The dust suppression structure can be fixed and disassembled by the fixing components. After unlocking the ratchet and pawl, the torsion bar can be rotated. When the stop block is separated from the mounting plate, the entire dust suppression structure can be disassembled and removed, which is convenient for disassembly, cleaning and maintenance. The locking and unlocking method using ratchet and pawl helps to improve the efficiency of dust suppression structure assembly and disassembly. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A bag opening machine integrating large and small bags includes a support frame 1. Inside the support frame 1, a lifting component 2, a bag-tapping component 3, and a bag opening tank 4 are arranged in sequence. Inside and outside the bag opening tank 4, a dust suppression structure 5, a blowing component 6, and a negative pressure component 7 are respectively installed. The dust suppression structure 5 is detachably connected to the openable can 4 via a fixing component 8.

[0017] Reference Figure 1 As shown, the top and sides of the opening tank 4 are equipped with inlets. The lifting component 2 is used to lift the large bags. The large bags are quickly discharged under the action of the bag-beating component 3 and enter the tank through the inlet on the top of the opening tank 4. The small bags are directly fed into the inlet on the side of the opening tank 4 by manual labor. The specific implementation method and structure are all existing technologies. For details, please refer to the ton bag machine. It will not be elaborated here. It should be added that a vibration motor is fixedly connected to the outer wall of the bottom discharge port of the opening tank 4.

[0018] Furthermore, the interior of the can 4 has a feeding chamber 41 and an installation chamber 42. The feeding chamber 41 is connected to the installation chamber 42. A partition 43 and the dust suppression structure 5 are fixedly connected inside the installation chamber 42. The opening can 4 is also fixedly connected to a sealing plate 44 at the opening of the mounting cavity 42.

[0019] Furthermore, the working ends of both the blow-jet assembly 6 and the negative pressure assembly 7 extend into the mounting cavity 42.

[0020] Reference Figure 2 , 3As shown, the negative pressure assembly 7 includes a negative pressure fan, which is fixedly connected to the side of the openable can 4, and the working end of the negative pressure fan is connected to the mounting cavity 42. The blowing assembly 6 includes an air tank, which is fixedly connected to the side of the opening can 4. The working end of the air tank is connected to the blowing main pipe, which extends into the mounting cavity 42. The bottom of the nozzle is also connected to a blowing branch pipe corresponding to the filter cartridge 52. A shaft seal is provided between the blowing main pipe and the opening can 4. Specifically, the blow-jet main pipe and the air tank can be connected by a quick connector. The specific structure of the quick connector can refer to the hydraulic pipe ball quick-release connector in the existing technology. After the blow-jet main pipe is separated from the air tank, it can be directly taken out through the opening of the mounting cavity 42, so that the dust suppression structure 5 can be disassembled.

[0021] More specifically, the dust suppression structure 5 includes an mounting plate 51 and a plurality of filter cartridges 52. The filter cartridges 52 are fixedly connected to the mounting plate 51. The mounting plate 51 is erected on top of the partition 43 and connected to it by a positioning structure 9.

[0022] Reference Figure 3 As shown, the positioning structure 9 includes positioning posts and positioning grooves. Several positioning posts are fixedly connected to the end face of the partition plate 43. The mounting plate 51 is provided with positioning grooves (not shown in the figure) corresponding to the positioning posts. The positioning grooves are movably inserted into the positioning posts to lock the position. So when the two ends of the mounting plate 51 are pressed and fixed by the fixing component 8, the movement of the mounting plate 51 can be prevented. Of course, a sealing structure such as a sealing gasket can be provided between the mounting plate 51 and the partition plate 43.

[0023] In general, the fixing component 8 includes torsion bars 81, which are rotatably connected to both sides inside the mounting cavity 42. Each of the two torsion bars 81 has a stop block 82 fixedly connected to its outer wall. The torsion bars 81 are rotated half a turn to drive the stop block 82 to press against the side of the mounting plate 51.

[0024] Finally, it also includes a ratchet 83 and two pawls 84. The ratchet 83 is fixedly connected to the end of the torsion bar 81, and the two pawls 84 are rotatably connected to the inner wall of the mounting cavity 42 through a shaft and a torsion spring 85. Two pawls 84 are disposed on both sides of the ratchet 83, and respectively lock the ratchet 83 in the clockwise and counterclockwise directions; The end of the pawl 84 extends outward to form a force-applying part 86.

[0025] Reference Figure 4 , 5As shown, after the torsion bar 81 is rotated to the position, the abutment 82 connected to its outer wall presses against the mounting plate 51. The torsion bar 81 can prevent the abutment 82 from separating from the mounting plate 51 through the locking action of the ratchet 83 and the pawl 84. In addition, the torsion bar 81 has an L-shaped structure, and its length direction is not at the same horizontal position as the end of the abutment 82. Those skilled in the art will easily understand that rubber parts can be provided on both sides of the end face of the mounting plate 51, and the abutment block 82 presses against the rubber parts, causing the rubber parts to deform and bear force to better press against the mounting plate 51, preventing the mounting plate 51 and the abutment block 82 from having a hard contact that affects the fastening effect. Of course, under the action of the positioning structure 9, the two ends of the mounting plate 51 are spaced apart from the two side walls of the mounting cavity 42 to ensure that the abutment block 82 can play a role in making way after rotation.

[0026] Specifically, pawls 84 are provided on both sides of the ratchet 83. For example, unlocking the right pawl 84 can rotate the torsion bar 81 to unlock the mounting plate 51. During the unlocking process, the left pawl 84 is locked to the ratchet 83 to prevent the stop block 82 from resetting and affecting the subsequent installation of the mounting plate 51. More specifically, the claws of the two pawls 84 are set in opposite directions.

[0027] Working method: During the ton bag feeding process, the negative pressure component 7 works with the dust suppression structure 5 to suppress the flying dust. After the feeding is completed, the negative pressure component 7 stops operating, and the blowing and spraying component 6 cleans the dust around the filter cartridge 52 by air jet. The dust is discharged through the feeding port. When the filter cartridge 52 needs to be disassembled and maintained, remove the sealing plate 44 and the blow-jet assembly 6, unlock the pawl 84 and rotate the torsion bar 81. After the stop block 82 is separated from the mounting plate 51, the mounting plate 51 can be taken out directly. Similarly, after the mounting plate 51 is installed in place, the other pawl 84 is unlocked and the torsion bar 81 is rotated in the opposite direction. The stop block 82 stops against the mounting plate 51 and, together with the locking action of the ratchet 83 and the pawl 84, the mounting plate 51 can be fixed.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
