Through the supporting cavity and printing and dyeing components, printing and dyeing operations can be performed simultaneously on the upper and lower surfaces of the packaging paper bag, resulting in high printing and dyeing efficiency; the fan and air outlet allow for intermittent airflow to the packaging paper bag, facilitating complete opening of the packaging paper bag and ensuring high printing and dyeing quality.

[0004] Regarding the aforementioned related technologies, the applicant discovered that in the operation of a two-way color printing and dyeing device for packaging paper bags, the printing head prints on the packaging paper bags, but the printing head is not dustproofed. When the printing and dyeing device is not in operation, the printing head is exposed to the environment for a long time, which easily accumulates dust, affecting the effect of the next printing and dyeing operation, and thus reducing the quality of the finished product after printing and dyeing the packaging paper bags. Therefore, we propose a two-way color printing and dyeing device for packaging paper bags. Utility Model Content

[0032] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0033] Please see Figure 1 and Figure 2 The figure shows a two-way color printing and dyeing device for packaging paper bags, including a worktable 1 and a boss 101. The boss 101 is fixedly connected to the worktable 1. Printing and dyeing components 2 are installed on the top and bottom of the worktable 1. The printing and dyeing components 2 include a movable frame 201. A printing and dyeing head 202 is fixedly installed on one side of the outer wall of the movable frame 201. A cylinder 203 is fixedly connected to the outer wall of the worktable 1. A fixed frame 204 is fixedly connected to the outer wall of the cylinder 203. The telescopic end of the fixed frame 204 is fixedly connected to the movable frame 201. It should be noted that the process algorithm and program involved in the working process of the printing and dyeing head 202 in this utility model are not within the protection scope of this utility model. Moreover, the process algorithm and program involved can be obtained by those skilled in the art through conventional technology. Therefore, it is only used for those skilled in the art to understand the application of the printing and dyeing head 202 in this utility model.

[0034] When performing bidirectional printing on the packaging paper bag, the packaging paper bag is first placed on the boss 101. Then, the fixing frame 204 in the printing and dyeing assembly 2 is activated. By controlling the fixing frame 204, the moving frame 201 and the printing head 202 are moved closer to the packaging paper bag. The bidirectional printing and dyeing of the packaging paper bag is achieved through the contact between the printing head 202 and the packaging paper bag.

[0035] Please see Figures 1-4 The dustproof component 3 is installed on the top of the movable frame 201 shown in the figure. The dustproof component 3 includes a fixing sleeve 301, which is fixedly connected to the movable frame 201. There are two sets of fixing sleeves 301, which are arranged opposite each other. Each set of fixing sleeves 301 has two fixing sleeves. The inside of the fixing sleeve 301 is hollow. A sliding rod 302 is slidably connected to one end of the fixing sleeve 301. The end of the sliding rod 302 away from the baffle 303 is T-shaped, which can limit the sliding rod 302. The bottom of the sliding rod 302 is fixedly connected to the baffle 303. The top of the movable frame 201 is fixedly installed with... There is a fixed base 304, which is located between two fixed sleeves 301. The fixed base 304 is rotatably connected to the inside of the fixed base 304. The bottom of the fixed base 305 is connected to a toothed plate 307 through a gear 306. There are two toothed plates 307, which are arranged opposite each other and mesh with the gear 306. The toothed plates 307 are fixedly connected to the slide rod 302 through a transmission block 308. The outer walls of the two fixed sleeves 301 are provided with limiting grooves 3081 for the transmission block 308 to slide. The limiting grooves 3081 are connected to the inside of the fixed sleeves 301.

[0036] When driving the baffle 303 in the dustproof component 3, manually turn the handle 305 clockwise to drive the gear 306 to rotate synchronously. Under the rotation of the gear 306, the toothed plate 307, transmission block 308, slide rod 302 and baffle 303 are driven to move horizontally to both sides of the printing head 202 until the printing head 202 is completely exposed. Conversely, the printing head 202 can be completely covered. Then, by driving the gear 306 through the handle 305 in the dustproof component 3, the baffle 303 is opened and closed at the bottom of the printing head 202. This allows the printing head 202 to be effectively protected from dust in different scenarios, while also ensuring the effective operation of the printing and dyeing process. This improves the printing and dyeing effect of the printing head 202 when printing and dyeing packaging paper bags, and improves the quality of the finished product after printing and dyeing the packaging paper bags.

[0037] Please see Figures 1-5As shown in the diagram, a fixing component 4 is fixedly installed on the outer wall of the fixing base 304. The fixing component 4 includes a ratchet 401, which is fixedly connected to a throttle handle 305. A pawl 402 is rotatably connected to the outer wall of the fixing base 304 near the ratchet 401. The pawl 402 engages with the ratchet 401. A lever 4021 is fixedly connected to one end of the pawl 402. A return spring 403 is fixedly installed between the pawl 402 and the fixing base 304.

[0038] The bottom of the lever 4021 is fixedly connected to a hemispherical locking block 404, which is made of elastic plastic. The outer side wall of the fixing base 304 is provided with a slot 4041 for the hemispherical locking block 404 to engage.

[0039] While the throttle 305 is rotated, the clockwise rotation of the throttle 305 simultaneously drives the ratchet 401 to rotate, pushing the pawl 402 to one side. Simultaneously, the movement of the pawl 402 compresses the return spring 403. When the baffle 303 is fully unfolded, the pawl 402 automatically engages with the ratchet 401 under the elastic force of the return spring 403, thus automatically locking the unfolded baffle 303. Before the throttle 305 is rotated counterclockwise, the lever 4021 is moved to disengage the pawl 402 from the ratchet 401. The ratchet 402, while simultaneously driving the hemispherical locking block 404 to move and deform, continues to drive the throttle 305 until it is fully engaged. Then, the pawl 402 drives the lever 4021 and the hemispherical locking block 404 to reset, causing the hemispherical locking block 404 to engage with the slot 4041, thereby fixing the throttle 305. Through the cooperation between the ratchet 401, ratchet 402, hemispherical locking block 404, and slot 4041 in the fixing component 4, the baffle 303 is effectively fixed after opening and closing, thus ensuring the stability of the dustproof component 3 during operation and improving the practicality of the device in use.
