Description

Technical Field

[0001] This utility model relates to the field of waste bag packaging technology, specifically a waste bag packaging device. Background Technology

[0002] Waste bag baling typically refers to the process of collecting, sorting, compressing, and baling waste plastic bags, woven bags, etc., commonly used in the waste recycling industry to facilitate transportation and subsequent processing. It reduces "white pollution" caused by the indiscriminate disposal of waste bags, mitigating harm to soil, water sources, and the ecosystem. It also promotes the recycling of plastic resources and conserves raw materials such as petroleum. Recycled waste bags can be processed into recycled plastic pellets for the production of new plastic bags, plastic pipes, woven products, etc.

[0003] Chinese utility model patent CN217075053U discloses a waste bag baling device, comprising: a baling frame; a pressing component and an ejection component installed on the baling frame; the baling frame having a collection space and a storage space; the collection space being located above the storage space and connected to the storage space through a collection channel; the pressing component including: a horizontal pushing cylinder, a horizontal guide rail, a vertical pushing cylinder, and a pressing roller; the ejection component including: an ejection cylinder and a push plate; the ejection cylinder being installed at one end of the storage space; the push plate being fixedly connected to one end of the cylinder rod of the ejection cylinder; and an opening being formed at the other end of the storage space for ejecting waste bags from the storage space. This utility model can automatically bale waste bags, realizing automated waste bag baling, greatly saving labor, improving work efficiency, effectively saving costs, and this baling method results in neat baling, accurate baling quantity, and avoids the impact of residual materials in the waste bags on human health.

[0004] However, during the use of this utility model, when the waste bag enters the storage space, there is no structure to continue compressing the waste bag, which causes the waste bag to expand after automatically absorbing air, failing to achieve a good compression and packaging effect and failing to meet production needs. Therefore, a waste bag packaging device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a waste bag baling device with the advantage of good compression effect. It solves the problem that existing baling devices do not have a structure to continue compressing the waste bag when it enters the storage space, which causes the waste bag to automatically absorb air and expand, thus failing to achieve a good compression and baling effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste bag baling device, including a base and a conveying cylinder fixedly connected to the top of the base, wherein a feeding hopper is fixedly connected to the top of the conveying cylinder, and a continuous feeding mechanism capable of continuously feeding waste bags is provided on the top of the feeding hopper.

[0007] The continuous feeding mechanism includes a support frame fixedly connected to the outside of the hopper and extending to its top. A first motor is fixedly connected to the top of the support frame. A rotating plate is fixedly connected to the output shaft of the first motor. A connecting plate is provided on the top of the support frame. A protrusion extending into the connecting plate is fixedly connected to one side of the rotating plate. An mounting sleeve is fixedly connected to the side of the connecting plate away from the protrusion. A lifting rod extending into the hopper is fixedly connected inside the mounting sleeve. A feeding plate is fixedly connected to the bottom end of the lifting rod.

[0008] Furthermore, the connecting plate has a positioning groove inside that matches the protrusion, and the lifting rod is connected to the support frame by a sliding connection.

[0009] Furthermore, a connecting pipe is fixedly connected between the discharge hopper and the conveying cylinder, and the protrusion is located on the side of the rotating plate away from the output shaft of the first motor.

[0010] Furthermore, a second motor is fixedly connected to one side of the conveying cylinder, and a spiral conveying rod extending into the interior of the conveying cylinder is fixedly connected to the output shaft of the second motor.

[0011] Furthermore, a packing box is fixedly connected to the top of the base, and the side of the conveying cylinder away from the second motor is connected to the packing box.

[0012] Furthermore, a hydraulic cylinder extending into the top of the packing box is fixedly connected, and a compression plate is fixedly connected to the output end of the hydraulic cylinder.

[0013] Furthermore, sharp teeth are fixedly connected to the lower surface of the compression plate, and a discharge box door is hinged to the side of the packing box away from the conveyor cylinder.

[0014] Furthermore, there are two hydraulic cylinders, which are symmetrically distributed on the left and right sides of the top of the packing box.

[0015] Compared with the prior art, the present invention provides a waste bag baling device, which has the following beneficial effects:

[0016] 1. This waste bag baling device uses a first motor to drive a rotating plate and a protrusion to rotate. A connecting plate and a positioning groove are also included. During the rotation of the protrusion, the connecting plate and mounting sleeve move up and down, which in turn drives the lifting rod and feeding plate to reciprocate. This facilitates the conveying of waste bags into the conveying cylinder, achieving continuous feeding. Workers only need to place the waste bags into the hopper, improving work efficiency.

[0017] 2. This waste bag baling device uses a second motor to drive a spiral conveyor to rotate, which transports the waste bags into the baling box. Then, a hydraulic cylinder drives a compression plate to move downward, which compresses and bales the waste bags. This prevents the waste bags from re-expanding, solving the problem in existing baling devices where there is no structure to continue compressing the waste bags when they enter the storage space, which causes the waste bags to automatically absorb air and expand, resulting in poor compression and baling effects.

[0023] 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.

[0024] Please see Figures 1 to 3The waste bag packaging device in this embodiment includes a base 1 and a conveying cylinder 2 fixedly connected to the top of the base 1. A feeding hopper 3 is fixedly connected to the top of the conveying cylinder 2. A continuous feeding mechanism capable of continuously feeding waste bags is provided on the top of the feeding hopper 3. The continuous feeding mechanism includes a support frame 4 fixedly connected to the outside of the feeding hopper 3 and extending to its top. A first motor 5 is fixedly connected to the top of the support frame 4. A rotating plate 6 is fixedly connected to the output shaft of the first motor 5. A connecting plate 7 is provided on the top of the support frame 4. A protrusion 8 extending into the interior of the connecting plate 7 is fixedly connected to one side of the rotating plate 6. An installation sleeve 9 is fixedly connected to the side of the connecting plate 7 away from the protrusion 8. A lifting rod 10 extending into the interior of the feeding hopper 3 is fixedly connected inside the installation sleeve 9. A feeding plate 11 is fixedly connected to the bottom end of the lifting rod 10.

[0025] Specifically, the connecting plate 7 has a positioning groove 12 that matches the protrusion 8 inside. The lifting rod 10 is connected to the support frame 4 by a sliding connection. The hopper 3 and the conveying cylinder 2 are fixedly connected by a connecting pipe 13. The protrusion 8 is located on the side of the rotating plate 6 away from the output shaft of the first motor 5.

[0026] It should be noted that by setting the first motor 5 to drive the rotating plate 6 and the protrusion 8 to rotate, and by setting the connecting plate 7 and the positioning groove 12, the protrusion 8 can drive the connecting plate 7 and the mounting sleeve 9 to move up and down during the rotation, which in turn can drive the lifting rod 10 and the feeding plate 11 to reciprocate, thus facilitating the conveying of waste bags into the conveying cylinder 2, thereby achieving the effect of continuous feeding.

[0027] Please see Figure 1 In this embodiment, a second motor 14 is fixedly connected to one side of the conveying cylinder 2, and a spiral conveying rod 15 extending into the interior of the conveying cylinder 2 is fixedly connected to the output shaft of the second motor 14.

[0028] Please see Figure 1 and Figure 4 In this embodiment, a packing box 16 is fixedly connected to the top of the base 1, and the side of the conveying cylinder 2 away from the second motor 14 is connected to the packing box 16. A hydraulic cylinder 17 extending into the top of the packing box 16 is fixedly connected, and a compression plate 18 is fixedly connected to the output end of the hydraulic cylinder 17.

[0029] Specifically, sharp teeth are fixedly connected to the lower surface of the compression plate 18, and a discharge box door 19 is hinged to the side of the packing box 16 away from the conveying cylinder 2. There are two hydraulic cylinders 17, which are symmetrically distributed on the left and right sides of the top of the packing box 16. By setting sharp teeth, the waste bags are prevented from sliding during the compression process, which would cause uneven compression or reduced efficiency. For fluffy waste bags (such as plastic shopping bags), the toothed structure can puncture the waste bags to release air and improve the compression density.

[0030] It should be noted that a controller is fixedly connected to the front of the packing box 16. The two hydraulic cylinders 17 are driven synchronously to balance the pressure on both sides in real time, ensuring that the compression plate 18 moves vertically. The load is shared by the two cylinders, and the working pressure of a single cylinder is reduced, which can reduce the wear of components such as seals and piston rods and extend the maintenance cycle. When the two cylinders are arranged in parallel or symmetrically, they can provide driving force synchronously, so that the total compression force is increased to twice that of a single cylinder. More waste bags can be compressed in the same amount of time, which is especially suitable for scenarios with large processing volumes.

[0031] It should be noted that the technical solution of this application can use a synchronization device such as a synchronization controller or a synchronization valve to ensure that the piston rods of the two hydraulic cylinders 17 extend and retract simultaneously, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of pneumatic control, and therefore will not be described in detail in the specific embodiments.

[0032] The working principle of the above embodiments is as follows:

[0033] First, the staff simultaneously starts the first motor 5 and the second motor 14. At this time, the first motor 5 drives the lifting rod 10 and the feeding plate 11 to move up and down reciprocally. The waste bag is then placed into the hopper 3. The feeding plate 11 then squeezes the waste bag downwards until it enters the conveying cylinder 2. After that, the second motor 14 drives the spiral conveying rod 15 to rotate, conveying the waste bag into the packing box 16. When there are enough waste bags in the packing box 16, the hydraulic cylinder 17 can be activated to move the compression plate 18 downwards to compress and pack the waste bags.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
