Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for the production and processing of plastic packaging bags. Background Technology

[0002] In the production and processing of plastic packaging bags, the feeding stage is a crucial step in raw material supply, directly affecting the stability and product quality of subsequent processes such as molding and sealing. Currently, the feeding devices commonly used in the industry mostly consist of a hopper, a conveying mechanism, and a discharge structure. Their core function is to continuously transport plastic raw materials (such as granules and powders) to the next production stage according to a set amount.

[0003] However, existing feeding devices have many limitations in practical applications: First, it is inconvenient to adjust the discharge amount. Traditional material blocking structures are mostly fixed in size or directly locked with bolts. Adjusting the feeding amount as needed can easily lead to overfeeding or underfeeding, affecting the uniformity of the packaging bag thickness and the utilization rate of raw materials. Second, the adjustment operation is cumbersome. Some devices require stopping the machine and disassembling parts to adjust the material blocking gap, which not only reduces production efficiency but also increases the intensity of manual operation. Utility Model Content

[0005] A belt conveyor for the directional transport of materials;

[0006] A hopper is installed on top of the belt conveyor and is arranged in a C-shape.

[0007] A material blocking device is installed at the opening of the hopper and is used to block the material according to the discharge rate.

[0008] The discharge chute is installed at one end of the belt conveyor.

[0009] Preferably, the material blocking device includes:

[0010] A fixing plate is fixedly installed at the opening of the hopper, forming a U-shaped structure with the hopper. The fixing plate is used to block the material.

[0011] A limiting frame, which is fixedly installed on a fixing plate;

[0012] An adjustable baffle mechanism is slidably disposed inside the limiting frame. The adjustable baffle mechanism can be vertically adjusted relative to the fixed plate to control the output amount.

[0013] Preferably, the adjustable stop mechanism includes:

[0015] The slider is slidably engaged with the limiting frame;

[0016] A locking component is fixedly connected to the slider and slidably engaged with the limiting frame.

[0017] Preferably, the locking component includes:

[0018] Mounting base, which is fixedly connected to the slider;

[0019] A snap-fit ​​component, which is slidably disposed inside the mounting base and is slidably snap-fitted with the limiting frame;

[0020] The unlocking component is slidably engaged with the top of the mounting base and is used to unlock the snap-fit ​​component by compression.

[0021] An elastic support member is connected to an unlocking member, and the elastic support member is used to provide elastic support for the unlocking member.

[0022] Preferably, the snap-fit ​​component includes:

[0023] A sliding frame is slidably disposed inside the mounting base, and inclined grooves are provided on both sides of the sliding frame;

[0024] The card blocks are symmetrically mounted on the sliding frame, which slides in conjunction with the mounting base. The limiting frame has multiple card slots symmetrically opened, and the card blocks and the inner cavities of the card slots cooperate with each other.

[0025] Preferably, the unlocking component includes:

[0026] A movable frame, which is slidably disposed inside the mounting base and disposed on the inner side of the sliding frame;

[0027] The extrusion column is connected to both sides of the movable frame and slides in conjunction with the inner cavity of the inclined groove.

[0029] Preferably, the elastic support member includes:

[0030] A skateboard, which is fixedly connected to a movable frame, has guide rods slidably inserted on it, and the guide rods are fixedly installed inside the mounting base;

[0031] A spring is sleeved on the outside of a guide rod, and the guide rod is used to provide elastic support for the slide plate.

[0032] This utility model discloses a feeding device for the production and processing of plastic packaging bags, which has the following beneficial effects:

[0033] By utilizing the cooperation between the fixed plate and the adjustable baffle mechanism, and through the limit frame, the sliding baffle plate's movement is easily limited, making its lifting and sliding more stable. Since there is a discharge gap between the fixed plate and the belt conveyor, when material is added to the hopper, the belt conveyor allows the material to be discharged through this gap into the production unit. Adjusting the position of the sliding baffle plate allows it to extend relative to the fixed plate, reducing the discharge gap and thus the discharge volume. This solves the problem of difficulty in adjusting the discharge volume as needed due to the fixed or inconvenient adjustment of traditional baffle structures, effectively preventing overfeeding or underfeeding, ensuring uniform packaging bag thickness, improving raw material utilization, and eliminating the need for machine downtime for adjustments. This significantly improves production efficiency and is particularly suitable for production scenarios requiring frequent adjustments to the discharge volume. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0043] This utility model provides, for example Figure 1-5 The device shown is a feeding device for the production and processing of plastic packaging bags, comprising: a belt conveyor 1 for directional conveying of materials; a hopper 2 installed on top of the belt conveyor 1 and arranged in a C-shape; a material blocking device 3 installed at the opening of the hopper 2 and used to block materials according to the discharge volume; and a discharge chute 4 installed at one end of the belt conveyor 1.

[0044] The material blocking device 3 includes: a fixed plate 31, which is fixedly installed at the opening of the hopper 2, forming a U-shaped structure with the hopper 2, and is used to block the material; a limiting frame 32, which is fixedly installed on the fixed plate 31; and an adjustable material blocking mechanism 33, which is slidably disposed inside the limiting frame 32. The adjustable material blocking mechanism 33 can be vertically adjusted relative to the fixed plate 31 to control the discharge amount. The limiting frame 32 facilitates the limiting of the sliding material blocking plate 331, making the lifting and sliding of the sliding material blocking plate 331 more stable. Since there is a discharge gap between the fixed plate 31 and the belt conveyor 1, when the material is added into the hopper 2, it is conveyed by the belt. The operation of machine 1 allows materials to be fed out from the gap between the fixed plate 31 and the belt conveyor 1, so that they can be put into the production device. By adjusting the position of the sliding baffle 331, the sliding baffle 331 can extend relative to the fixed plate 31, thereby extending the length of the fixed plate 31 downward, reducing the discharge gap, and thus facilitating the reduction of the discharge amount. This solves the problem that the discharge amount is difficult to adjust as needed due to the fixed or inconvenient adjustment of the traditional baffle structure. It effectively avoids the situation of too much or too little material feeding, ensures the uniformity of the packaging bag thickness, improves the utilization rate of raw materials, and does not require machine stoppage for adjustment, significantly improving production efficiency. It is especially suitable for production scenarios that require frequent adjustment of the discharge amount.

[0045] The adjustable baffle mechanism 33 includes: a sliding baffle plate 331, which is slidably disposed relative to the fixed plate 31 and is slidably disposed inside the limiting frame 32, with bristles at the bottom; a slider 332, which is slidably engaged with the limiting frame 32; and a locking component 333, which is fixedly connected to the slider 332 and slidably engaged with the limiting frame 32. The position of the sliding baffle plate 331 relative to the fixed plate 31 can be adjusted. When it is necessary to adjust the discharge amount, simply operate the sliding baffle plate 331 to extend or retract relative to the fixed plate 31 to change the discharge gap between the fixed plate 31 and the belt conveyor 1. When the sliding baffle 331 extends downwards, the discharge gap decreases, and the discharge volume decreases accordingly. When the sliding baffle 331 retracts upwards, the discharge gap increases, and the discharge volume increases accordingly. This solves the problem of difficulty in adjusting the discharge volume as needed due to the fixed or inconvenient adjustment of traditional baffle structures. By sliding the sliding baffle 331 in conjunction with the slider 332 on the limiting frame 32, the position of the sliding baffle 331 can be directly adjusted. Then, the locking component 333 can be used to fix it. The limiting frame 32 plays a good limiting role in the sliding of the sliding baffle 331, making the lifting and sliding of the sliding baffle 331 more stable and avoiding displacement or shaking under material impact. At the same time, the locking component 333 can firmly lock the sliding baffle 331 in the set position, further ensuring the stability of the discharge gap, reducing problems such as discharge deviation and material leakage caused by structural loosening, reducing the maintenance frequency of the equipment, and ensuring the continuity of production.

[0046] The locking component 333 includes: a mounting base 3331, which is fixedly connected to the slider 332; a snap-fit ​​component, which is slidably disposed inside the mounting base 3331 and is slidably snap-fitted with the limit frame 32; an unlocking component, which is slidably engaged with the top of the mounting base 3331 and is used to unlock the snap-fit ​​component by compression; and an elastic support component, which is connected to the unlocking component and is used to provide elastic support for the unlocking component.

[0047] The locking components include: a sliding frame 3332, which is slidably disposed inside the mounting base 3331, with inclined grooves on both sides of the sliding frame 3332; and locking blocks 3333, which are symmetrically mounted on the sliding frame 3332, with the sliding frame 3332 and the mounting base 3331 in a sliding fit. The limiting frame 32 has multiple symmetrically arranged locking slots, with the locking blocks 3333 engaging with the inner cavities of the locking slots. The unlocking components include: a movable frame 3334, which is slidably disposed inside the mounting base 3331 and located inside the sliding frame 3332; pressing columns 3335, which are respectively connected to both sides of the movable frame 3334 and in a sliding fit with the inner cavities of the inclined grooves; and a pressing plate 3336, which is slidably disposed on the top of the mounting base 3331, with its end fixedly connected to the movable frame 3334. The elastic support component includes: a sliding plate 3337, which is fixedly connected to the movable frame 3334. A guide rod is slidably inserted on the sliding plate 3337 and fixedly installed inside the mounting base 3331; and a spring 3338, which is sleeved on the outside of the guide rod. The guide rod provides elastic support for the sliding plate 3337. This elastic support from the spring 3338 facilitates a more stable fit between the locking block 3333 and the locking slot. When the position of the sliding baffle 331 needs adjustment... When the extrusion plate 3336 is extruded, the moving frame 3334 is pushed to move vertically downward. Through the cooperation between the extrusion column 3335 and the inclined groove, the force component is facilitated, so that the downward movement of the extrusion column 3335 can push the sliding frame 3332 to slide linearly in the direction of the spring 3338. In order to bring the locking block 3333 out of the inner cavity of the slot through the sliding frame 3332, the locking component 333 and the limiting frame 32 are unlocked, thereby facilitating the adjustment of the height position of the sliding baffle plate 331.
