Description

Technical Field

[0001] The invention belongs to the technical field of packaging bag processing, and in particular relates to an ironing and pressing device for packaging bag processing. Background Art

[0002] There are generally three types of existing packaging bags: with a spout, without a spout, and with a false spout. A spout means that the packaging bag has a connecting spout and a spout cover, which can make the packaging bag open and close repeatedly; a spout means that the packaging bag has no connecting spout, and the entire packaging bag needs to be torn open to open the packaging bag.

[0003] The false mouth is a diversion channel on the packaging bag that is connected to the inner cavity. It is generally a flexible structure that protrudes outward from the edge of the packaging bag. This flexible structure is integrated with the packaging bag and has the effect of diverting the fluid inside the packaging bag. The false mouth packaging bag is mostly a disposable packaging bag and is used for packaging fluid products. However, the bag opening of this packaging bag is easily attracted to each other by static electricity, resulting in incomplete opening of the bag opening. When pouring the fluid in the bag, the incompletely opened bag opening is likely to make it difficult for the fluid to be poured out of the bag, and the flexible bag opening is also likely to cause the fluid to flow along the bag opening, which is inconvenient to use. For this reason, the present invention designs a hot pressing device for packaging bag processing, and a hard conduit is hot-melt connected to the inner side of the false mouth of the packaging bag. The hard conduit can prevent the extended guide part from being unable to be fully opened due to the influence of static electricity. When pouring, the fluid can smoothly flow out through the hard conduit under pressure, and the conduit is made of hard material, so it is not easy to collapse during the pouring process, which is convenient for users to pour, and the use effect is better than that of the false mouth packaging bag. Summary of the invention

[0004] The purpose of the present invention is to provide a hot pressing device for packaging bag processing, so as to solve the problems raised in the background technology.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-6 As shown, a hot pressing device for packaging bag processing of the present invention comprises a base 1, a column 11 is fixed in the middle of the base 1, a circular seat 12 is fixed at the upper end of the column 11, a circular plate 13 is rotatably mounted on the side wall of the column 11, a driving assembly for driving the circular plate 13 to rotate is arranged in the column 11, and the circular plate 13 is mounted with four sets of evenly distributed mounting mechanisms;

[0029] A packaging bag limiting groove 14 is installed on the front side of the base 1, and a bag opening mechanism and a hot pressing mechanism matching the packaging bag limiting groove 14 are installed on the front side of the column 11;

[0030] The mounting mechanism includes a slide groove 2 provided on a circular plate 13, a rack 21 is slidably mounted in the slide groove 2, a fixed plate 22 is fixed at the lower end of the circular plate 13, the fixed plate 22 is rotatably mounted with a gear 23 meshing with the rack 21 through a rotating shaft, a first electric push rod 24 is obliquely mounted on the lower side of the gear 23, a clamping block 25 is mounted on the output shaft of the first electric push rod 24, a clamping assembly is arranged in the clamping block 25, a conveying guide rail 15 for conveying a hard catheter 0 is mounted on the left side of the base 1, a first spring 211 is arranged between the side of the rack 21 close to the column 11 and the side wall of the slide groove 2, a first annular groove 212 is provided on the side wall of the circular seat 12, a first push rod 213 extending into the first annular groove 212 is fixed at the end of the rack 21, and a first arc bar 214 matching the first push rod 213 is fixed on the left rear side of the first annular groove 212.

[0031] The clamping assembly includes an airbag 251 installed on the side wall of the clamping block 25 , an arc groove 252 is opened in the fixing plate 22 , the rotating shaft extends into the arc groove 252 and is connected to a sealing push plate 253 , and the lower side of the arc groove 252 is connected to the airbag 251 through a first hose 254 .

[0032] In the initial state, the clamping block 25 is in an inclined state as a whole, and can correspond to the false mouth of the packaging bag. Since the first push rod 213 can abut against the first arc-shaped bar 214 on the left side of the first annular groove 212, the rack 21 can be pushed to move in the slide groove 2, and the rack 21 can be driven to rotate, so that the clamping block 25 on the left side is in a vertical downward state, and the conveying guide rail 15 can convey the hard catheter 0 to the lower side of the clamping block 25 in this position. The inner side of the conveying guide rail 15 is provided with an extension guide rail 151;

[0033] When in use, the packaging bag is placed into the packaging bag limiting groove 14 by the external conveying mechanism, and the packaging bag is opened as a whole by the bag opening mechanism, and the false mouth of the packaging bag will also be opened, and then the circular plate 13 is driven to rotate by the rotating assembly. When the clamping block 25 rotates to the left and is located above the hard conduit 0, the first push rod 213 abuts against the first arc-shaped bar 214, so that the clamping block 25 is in a vertical state, and then the first electric push rod 24 pushes the clamping block 25 to move downward and extend into the hard conduit 0. Then the circular plate 13 continues to rotate, and the clamping block 25 drives the hard conduit 0 to move on the extension guide rail 151. The first push rod 213 will be out of contact with the first arc-shaped bar 214, and the elastic force of the first spring 211 pushes the rack 21 to slide, driving the gear 23 to When the gear 23 rotates, the clamping block 25 will return to the inclined state. During this process, when the gear 23 rotates, the sealing push plate 253 can be driven to rotate in the arc groove 252 through the rotating shaft, and the air in the arc groove 252 is pushed into the airbag 251 through the first hose 254. The airbag 251 will gradually expand and contact the inner wall of the hard conduit 0. Therefore, when the clamping block 25 is turned upward to be inclined, the hard conduit 0 can be automatically clamped and fixed to prevent the hard conduit 0 from falling. Then, the hard conduit 0 is driven to move upward by the first electric push rod 24 until the clamping block 25 rotates to the top of the packaging bag, and the hard conduit 0 is driven downward by the first electric push rod 24 to extend into the false mouth of the packaging bag. Finally, the hard conduit 0 is fixed inside the false mouth of the packaging bag by the hot pressing mechanism.

[0034] After the installation of the hard conduit 0 is completed, the circular plate 13 is started to continue to rotate, and the clamping block 25 will drive the packaging bag as a whole to rotate toward the rear side of the base 1 until the first push rod 213 and the first arc-shaped strip 214 are re-connected, and the clamping block 25 will flip to a vertical state, and the sealing push plate 253 rotates in the arc-shaped groove 252, and the air inside the airbag 251 can be drawn into the arc-shaped groove 252. The airbag 251 will shrink and will not contact the inner wall of the hard conduit 0, so the packaging bag as a whole will fall downward by its own weight, realizing automatic unloading of the packaging bag. The circular plate 13 circulates in this way, and the hard conduit 0 can be automatically installed into the interior of the packaging bag, with a high degree of automation.

[0035] A first material receiving conveyor belt 16 is provided on the rear side of the base 1; the position of the first material receiving conveyor belt 16 corresponds to the rear end of the first arc-shaped strip 214, so when the first push rod 213 and the first arc-shaped strip 214 are re-engaged, the packaging bag as a whole will fall downward to the first material receiving conveyor belt 16, and the processed packaging bag as a whole will be transported to the next process through the first material receiving conveyor belt 16.

[0036] The bag opening mechanism includes a first double-axis motor 3 installed on the column 11, the output shaft of the first double-axis motor 3 is connected to the first connecting plate 31, and the end of the first connecting plate 31 is installed with a pneumatic suction cup 32; after the packaging bag is placed in the packaging bag limiting groove 14, the two pneumatic suction cups 32 are used to adsorb the two sides of the packaging bag, and then the two pneumatic suction cups 32 move away from each other, so that the false mouth of the packaging bag can be opened. After the hard catheter 0 is installed, the pneumatic suction cup 32 cancels the adsorption of the packaging bag and moves away from the packaging bag, and then the first double-axis motor 3 drives the pneumatic suction cup 32 to flip downward without blocking the packaging bag.

[0037] The ironing mechanism includes a second double-axis motor 33 installed on the column 11, the output shaft of the second double-axis motor 33 is connected to the second connecting plate 34, the end of the second connecting plate 34 is installed with a second electric control push rod 35, and the output shaft of the second electric control push rod 35 is connected to the ironing block 36; after the hard catheter 0 is installed, the second electric control push rod 35 drives the ironing block 36 to contact the packaging bag, and the packaging bag is melted by high temperature, so that the hard catheter 0 is fixed on the packaging bag. After the processing is completed, the second electric control push rod 35 is started to drive the ironing block 36 away from the packaging bag, and the second double-axis motor 33 drives the ironing block 36 to flip upward without blocking the packaging bag.

[0038] An air passage 4 is provided in the middle of the clamping block 25, a piston cylinder 41 is installed at the upper end of the rack 21, a piston plate 42 is provided in the piston cylinder 41 for sealing and sliding, a second spring 43 is provided between the lower side of the piston plate 42 and the bottom wall of the piston cylinder 41, an air inlet is provided at the bottom of the piston cylinder 41, and the air inlet is connected to the air passage 4 through a second hose 44, a second annular groove 45 is provided at the upper end of the circular seat 12, a second push rod 46 extending into the second annular groove 45 is fixed at the upper end of the piston plate 42, and a boss 47 matching the second push rod 46 is fixed at the front side of the second annular groove 45;

[0039] When the clamping block 25 transports the hard conduit 0 to the top of the packaging bag, the second push rod 46 abuts against the boss 47, and the piston plate 42 is located at the bottom of the piston cylinder 41. After the hard conduit 0 is installed, the air bag 251 is in close contact with the hard conduit 0, and the airway 4 is connected to the inside of the packaging bag. In this way, when the circular plate 13 continues to rotate, the second push rod 46 will be out of contact with the boss 47, and the elastic force of the second spring 43 will push the piston plate 42 to move upward, generating negative pressure to draw the air inside the packaging bag into the piston cylinder 41 through the second hose 44, until the first push rod 213 abuts against the first arc strip 214, and the air inside the air bag 251 is drawn into the arc groove 252, and the packaging bag falls downward by its own weight;

[0040] After the hard conduit 0 is installed, this design can draw a small amount of harmful gas entering the packaging bag into the piston cylinder 41, so that the harmful gas will not accumulate in the packaging bag.

[0041] A one-way air inlet valve is provided in the air inlet, an annular shell 5 is rotatably mounted on the outer side of the column 11, a one-way air outlet is also provided at the bottom of the piston cylinder 41, the one-way air outlet is connected to the annular shell 5 through a pipe 51, a channel 52 is provided inside the column 11, the channel 52 is connected to the annular shell 5 through an air hole, an air filter 53 is installed on the upper end of the circular seat 12, and the channel 52 is connected to the inside of the air filter 53;

[0042] A one-way air inlet valve is provided in the air inlet, so that air can only enter the piston cylinder 41 through the air inlet. When the piston plate 42 moves upward, the air inside the packaging bag can be drawn into the piston cylinder 41. When the piston plate 42 moves downward, the air can be pushed into the annular shell 5 through the one-way air outlet and the pipe 51, and finally enter the air filter 53 from the channel 52 for filtration to prevent harmful gases from being discharged to the outside. The annular shell 5 is arranged to rotate synchronously with the circular plate 13 to prevent the various components from getting stuck.

[0043] As an improvement of the previous embodiment, the capacity of the piston cylinder 41 is greater than that of the packaging bag, a second arc strip 6 is installed on the right side of the upper wall of the second annular groove 45, the inner side of the second arc strip 6 is processed with an inclined surface, and a second material receiving conveyor belt 17 is installed on the right side of the base 1;

[0044] When the piston plate 42 moves upward to draw the air inside the packaging bag into the piston cylinder 41, the air inside the packaging bag can be completely drawn into the piston cylinder 41, and the piston plate 42 will not move to the upper end of the piston cylinder 41, so the second push rod 46 will not contact the second arc-shaped strip 6, so the packaging bag can be conveyed to the first receiving conveyor belt 16;

[0045] When there is a gap between the rigid conduit 0 and the packaging bag after installation, the product is a low-quality product. At this time, the piston plate 42 moves upward to draw the air inside the packaging bag into the piston cylinder 41, and the outside air can enter the packaging bag through the gap, so the piston plate 42 can continue to move upward and finally abut against the upper wall of the piston cylinder 41. When the second push rod 46 moves to the right, it can contact the inclined surface of the second arc-shaped bar 6, and the second push rod 46 is pushed inward to move, which drives the rack 21 to move inward as a whole. The clamping block 25 will flip to a vertical state, and the airbag 251 will shrink and not contact the inner wall of the rigid conduit 0. Therefore, the packaging bag as a whole will fall downward by its own weight onto the second material receiving conveyor belt 17. Such a design can automatically separate low-quality products and has a simple structure.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
