Description

Technical Field

[0001] This utility model relates to the field of bag-making machine technology, specifically a bag-making machine that can quickly change bag types. Background Technology

[0002] The bag dispenser with quick bag type change is a small device for scanning and picking up bags in hospitals, public places and other scenarios. It is designed to meet the needs of quick adaptation to different bag sizes (such as medical waste bags, eco-friendly shopping bags, etc.).

[0003] The bag dispenser is equipped with a modular bag compartment that can be quickly disassembled and assembled. Through snap-on connection and precise positioning structure, the staff can change different bag types in seconds without professional tools. It is compatible with common bag shapes such as round and square, as well as bag materials of different sizes and thicknesses. The built-in intelligent sensor group replaces the traditional single detection element. Combined with pressure sensing and photoelectric collaborative monitoring technology, it can accurately judge the remaining amount of bag compartment in real time. When the bags are about to run out, it will automatically trigger an alarm and push a bag replenishment reminder to the management terminal to ensure the continuous smooth bag retrieval process.

[0004] However, in practical applications, it has been found that the infrared detector used to monitor the remaining amount of material rollers is prone to signal distortion and decreased accuracy due to the bag body blocking the signal. When the material rollers are exhausted, the discharge cylinder cannot trigger the ejection action in time, requiring manual shutdown for troubleshooting and replacement, interrupting the production process and reducing work efficiency. Therefore, a bag-discharging machine that can quickly change bag types is proposed to address the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bag-exiting machine with quick bag type change capability includes a bag-exiting machine body and a mounting frame. The mounting frame is fixed to the back of the bag-exiting machine body, and a dual-station material cylinder assembly is rotatably connected to the rear end of the mounting frame.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-6 This utility model provides a technical solution:

[0030] A bag-extruding machine with quick bag type change capability includes a bag-extruding machine body 1 and a mounting frame 2. The mounting frame 2 is fixed to the back of the bag-extruding machine body 1, and a dual-station material cylinder assembly 4 is rotatably connected to the rear end of the mounting frame 2. The dual-station material cylinder assembly 4 includes a discharge cylinder 41, with a mounting cavity 42, a limiting hole 44, and a positioning cavity 45 opened at both the top and bottom of the discharge cylinder 41. An automatic ejection mechanism 43 is installed at both ends inside the mounting cavity 42, and a set of spring telescopic rods 46 are fixed on both sides of the bottom end inside the mounting cavity 42. The automatic ejection mechanism 43 includes a drive seat 431, which is slidably disposed inside the mounting cavity 42. A support base 432 is fixed to the front end face of the moving base 431. A locking member 433 for locking the material roller is elastically connected to the center of the front end face of the support base 432 via a spring. A detection rod 434 for engaging with the limiting hole 44 is installed on the top of the support base 432. A spring member 435 providing elastic force is sleeved on one side of the outer wall of the detection rod 434. An oil storage groove 436 and a circularly arranged guide groove 437 are opened in the middle of the outer side of the detection rod 434. With this configuration, the detection rod 434 can accurately detect the remaining material roller. The engagement of the oil storage groove 436 and the guide groove 437 can reduce friction. The locking member 433 facilitates the installation of the material roller.

[0031] As a further implementation of this solution, each set of spring telescopic rods 46 is parallel to each other, and there are two spring telescopic rods 46 in each set. The two spring telescopic rods 46 are symmetrically distributed with the limiting hole 44 as the center. The telescopic end of the spring telescopic rod 46 is fixedly connected to the top of the rear end face of the drive seat 431. The symmetrically distributed spring telescopic rods 46 can provide a stable upward ejection driving force for the drive seat 431, ensuring that the drive seat 431 can eject the material roller in a timely and stable manner after the detection rod 434 is triggered.

[0032] As a further implementation of this solution, the bottom end of the support base 432 extends to the bottom of the drive base 431. The position of the support base 432 corresponds to the position of the positioning cavity 45. The bottom end of the support base 432 is embedded in the inner side of the positioning cavity 45. With this arrangement, the positioning cavity 45 plays a precise positioning and guiding role for the support base 432, ensuring that the support base 432 slides stably in the mounting cavity 42, thereby ensuring the overall stability of the automatic ejection mechanism 43.

[0033] As a further implementation of this solution, the detection rod 434 and the support base 432 are slidably fitted. The top of the front end face of the detection rod 434 has an arc-shaped structure, and the bottom of the front end face of the detection rod 434 has an inclined structure. Guide grooves 439 are provided on both sides of the rear end face of the detection rod 434. The arc-shaped and inclined front end face facilitates better contact and force distribution between the detection rod 434 and the bag wall. The inclined surface of the guide groove 439 facilitates the smooth insertion of the detection rod 434 into the limiting hole 44 during installation.

[0034] As a further implementation of this solution, the position of the guide groove 437 is parallel to the position of the detection rod 434. The oil storage groove 436 is located in the middle of the guide groove 437 and is connected to the guide groove 437. The inner side of the oil storage groove 436 is fitted with a sponge layer 438, which absorbs lubricating oil. When the detection rod 434 moves, the lubricating oil absorbed by the sponge layer 438 is transported through the guide groove 437 to the contact point between the detection rod 434 and the support base 432 and the limiting hole 44, forming an oil film, which greatly reduces friction and ensures the stability of the automatic ejection of the detection rod 434.

[0035] As a further implementation of this solution, a stepper motor 3 is fixed to one side of the mounting frame 2 via an electric mount. The position of the stepper motor 3 corresponds to the position of the dual-station material cylinder assembly 4. The drive shaft of the stepper motor 3 is fixedly connected to one end of the discharge cylinder 41 via a coupling. The stepper motor 3 provides power for the rotation of the discharge cylinder 41. The installation is stable due to the electric mount, and the coupling connection ensures stable power transmission, enabling the discharge cylinder 41 to rotate accurately and smoothly, thus realizing the bag discharge operation.

[0036] As a further implementation of this solution, a pressure detection rod 5 is fixed to the top of the rear end face of the mounting frame 2. The pressure detection rod 5 is located above the discharge cylinder 41, and a pressure sensor is installed on the lower surface of the pressure detection rod 5.

[0037] Work process: The material roller of the new bag is clamped between the two clamping parts 433 in the automatic ejection mechanism 43. The elastically connected clamping parts 433 provide room for installation, which facilitates the quick installation and fixing of the material roller. The automatic ejection mechanism 43 is manually reset so that the bottom end of the support base 432 is embedded in the positioning cavity 45. At this time, the detection rod 434 overcomes the elastic force of the spring part 435 under the action of external pressure and is inserted into the limiting hole 44. The spring telescopic rod 46 is in a compressed state.

[0038] When the stepper motor 3 is started, the drive shaft of the stepper motor 3 drives the discharge cylinder 41 to rotate through the coupling, and the bag discharge operation begins. When there is sufficient material roller, the side of the bag wall will continuously squeeze the detection rod 434, so that the detection rod 434 is stably held in the limiting hole 44. The spring telescopic rod 46 maintains the compressed state, and the automatic ejection mechanism 43 does not eject. During the rotation of the discharge cylinder 41 and the slight sliding of the detection rod 434, the sponge layer 438 in the oil storage tank 436 is affected by the thrust and delivers lubricating oil through the guide groove 437. An oil film is formed between the detection rod 434, the support base 432 and the limiting hole 44, reducing friction and ensuring smooth operation of the detection rod 434.

[0039] The pressure detection rod 5 does not contact the discharge cylinder 41 under normal conditions;

[0040] When the remaining material on the material roller gradually decreases until it is used up, the bag wall no longer applies pressure to the detection rod 434. Under the elastic force of the spring 435, the detection rod 434 is pushed outward and released from the restriction of the limiting hole 44. As the detection rod 434 is released from the limiting hole 44, the telescopic end of the spring telescopic rod 46 is unrestrained and extends upward, driving the drive seat 431 to move upward. The drive seat 431 drives the support seat 432 fixed at the front end to move upward together. The bottom end of the support seat 432 is released from the positioning cavity 45, thereby pushing the used material roller upward. The material roller applies pressure to the pressure sensor on the lower surface of the pressure detection rod 5, so that the back-end management terminal can detect the pressure change and promptly discover that the material has been used up.

[0041] The operator removes the exhausted material roller and repositions a new material roller between the two clamping parts 433. The operator then manually presses down on the drive seat 431, causing the spring telescopic rod 46 to compress again. The bottom end of the support seat 432 is then embedded in the positioning cavity 45. During this process, the detection rod 434 is compressed, overcoming the elasticity of the spring part 435, and re-inserts into the limiting hole 44, completing the reset of the automatic ejection mechanism 43. The stepper motor 3 is then restarted, and the bag ejector resumes normal bag ejection operation, repeating the above normal bag ejection stage process.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
