Description

Technical Field

[0001] This utility model relates to the field of bag-popping device technology, and more specifically, to an automatic bag-popping device. Background Technology

[0002] In the production workshop, small products usually need to be packaged in sealed bags after mass production. To facilitate subsequent batch packaging, the packaging bags are usually pre-fitted into barrels, cans, etc., and the bag openings are opened before being transferred to the packaging workshop for product acceptance. In the existing technology, in order to ensure that the bags are securely and evenly fitted into the barrels, traditional manual methods are used. This not only has problems such as low efficiency, high labor intensity, and poor operational consistency, but also makes it impossible to fit the bags into barrels with a certain height and volume, thus limiting the subsequent batch packaging volume.

[0003] Based on the above description, there is an urgent need for an automated bag-holding device that does not require manual bag holding. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic bag-opening device, which aims to solve the technical problems of the existing traditional method of manually opening bags, which is time-consuming, labor-intensive, inefficient, and affects the single-batch packaging volume of subsequent packaging processes.

Detailed Implementation

[0023] The specific implementation method is described below with reference to the accompanying drawings.

[0024] Example 1

[0025] Please see Figures 1 to 4 The present invention provides the following technical solution: an automatic bag-pouring device, which is suitable for situations where a bag is poked into the inside of a barrel.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, an automatic bag-blowing device includes a barrel 1, a frame 2, a bag-blowing assembly 3, and multiple film-supporting plates 4; the frame 2 is slidably connected to a mounting plate 5 in the vertical direction; the bag-blowing assembly 3 is telescopically connected to the bottom of the mounting plate 5 and extends towards the top opening of the barrel 1; the multiple film-supporting plates 4 are arranged around the outer side wall of the bag-blowing assembly 3; the multiple film-supporting plates 4 are slidably connected to the mounting plate 5 through a drive assembly 6; the multiple film-supporting plates 4 reciprocate along the radial direction of the bag-blowing assembly 3.

[0027] In this embodiment, the blow-bag assembly 3 and multiple film-supporting plates 4 are pre-inserted into the bag body. Then, the drive assembly 6 is activated, causing the multiple film-supporting plates 4 to move simultaneously away from the blow-bag assembly 3, thereby opening the bag opening and fixing the bag body to the multiple film-supporting plates 4. Furthermore, by extending and retracting the blow-bag assembly 3 towards the top opening of the barrel 1, the bag is blown while being inserted, and finally the bag body is opened and inserted into the interior of the barrel 1, and the bag body is evenly attached to the inner wall of the barrel 1, thus completing the efficient automatic bag opening.

[0028] In this embodiment, the frame 2 can be further provided with a vertical slide rail. The mounting plate 5 can be driven by an electric lifting rod to slide back and forth along the slide rail toward the barrel 1. This facilitates the blowing of bags in conjunction with the extension and retraction of the blowing bag assembly 3, and also facilitates the delivery of the bag to the bottom of the multiple film support plates 4 in the preparation stage, in conjunction with the bag preparation device, so that the automatic bag-poking device of this embodiment can be used to poke the bag into the barrel 1.

[0029] Specifically, such as Figure 4As shown, the bag blowing assembly 3 includes a bag-pumping cylinder 31, a telescopic nozzle 32, and an air blower 33; the bag-pumping cylinder 31 is connected to the mounting plate 5; the air blower 33 is connected to the bag-pumping cylinder 31; the telescopic nozzle 32 passes through the bag-pumping cylinder 31; the telescopic nozzle 32 extends out of the bag-pumping cylinder 31 and extends towards the top opening of the barrel 1. Multiple air blowing holes are provided on the side of the bag-pumping cylinder 31 away from the mounting plate 5.

[0030] In this embodiment, after air is blown by the air blower 33, it is emitted from multiple air holes on the bag-blowing cylinder 31. The multiple air holes are further arranged around the bag-blowing cylinder 31, so that when the bag is blown through the bag-blowing cylinder 31, the bag can be blown 360°, so that the bag, which was originally in a glued state, expands and opens inside the barrel 1 and sticks to the inner wall of the barrel 1, so that the bag is evenly inserted or fitted into the inside of the barrel 1. The telescopic nozzle 32 is a pneumatic or electric telescopic nozzle 32, which plays the role of blowing and opening the bag, improving the efficiency and effect of bag blowing.

[0031] Specifically, such as Figure 3 As shown, the mounting plate 5 is mounted on a pair of slide rails 51; the drive assembly 6 includes a pair of slide blocks 61; the slide blocks 61 are connected to the slide rails 51; both ends of the slide blocks 61 are provided with first connecting plates 7 extending vertically toward the barrel body 1; the film support plate 4 is surrounded on the outer wall of the blow-bag assembly 3 through the pair of first connecting plates 7. The drive assembly 6 also includes a pair of telescopic cylinders 62; the pair of telescopic cylinders 62 are positioned opposite each other on the top of the mounting plate 5; one end of the telescopic cylinder 62 is connected to the mounting plate 5; the other end of the telescopic cylinder 62 extends vertically toward the barrel body 1 with a second connecting plate 8; the film support plate 4 is surrounded on the outer wall of the blow-bag assembly 3 through the second connecting plate 8. A synchronous belt 9 connects the pair of slide blocks 61 and the pair of telescopic cylinders 62.

[0032] In this embodiment, the timing belt 9 enables the opening and closing of a pair of sliding blocks 61 and a pair of telescopic cylinders 62 to be synchronized, thereby realizing the simultaneous movement of multiple connected membrane plates 4.

[0033] In this embodiment, the membrane support plate 4 is preferably an arc-shaped plate, with an arc-shaped strip extending from its bottom end toward one side of the blow-bag assembly 3, such as... Figure 5 As shown, by further setting arc-shaped blocks, the bag opening portion is concavely fitted over the top of the barrel 1, as... Figure 2 As shown, this facilitates the bonding of the inner and outer bags during the subsequent heat sealing stage.

[0034] Specifically, such as Figure 1 and Figure 3 As shown, the bottom of the frame 2 is provided with a conveying mechanism 10; the barrel 1 is conveyed to the bottom of the blow-bag assembly 3 through the conveying mechanism 10. The top of the conveying mechanism 10 is provided with a conveying trough plate 11; the bottom end of the barrel 1 is embedded in the groove of the conveying trough plate 11; the conveying mechanism 10 is provided with a limiting strip plate 12 against the outer wall of the conveying trough plate 11.

[0035] In this embodiment, the conveying mechanism 10 adopts a roller conveyor. The barrel 1 is embedded in the conveying trough plate 11 and then placed on the roller conveyor for conveying. The conveying trough plate 11 is limited by the limiting strip plate 12 to ensure the stability of the barrel 1 when it is conveyed to the bottom of the blow-drying assembly 3.
