Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, specifically a plastic product recycling and crushing device and feeding structure. Background Technology

[0002] Because plastic products are difficult to degrade, they have recycling value. Plastic products are usually recycled, cleaned, and melted down for reuse.

[0003] When recycling plastic products, extrusion or crushing equipment is usually required to reduce the volume of the plastic products for easier recycling and subsequent processing. However, different plastic products have different materials. Some plastic products are harder and are prone to fragments flying off during extrusion and crushing, while others are softer and tend to form soft slag that adheres to the equipment. Therefore, a versatile recycling and crushing device is needed for plastic products of different materials. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a plastic product recycling and crushing device and feeding structure, which can crush and recycle plastic products of different materials, and avoid plastic products flying out or forming soft slag adhering to the equipment during the crushing process.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a feeding structure, including a push-pull assembly, the push-pull assembly including a push plate, a fixed rod, a fixed plate and a baffle, the fixed rod is fixedly connected to the fixed plate, the push plate is slidably connected to the fixed rod and the fixed rod passes through the push plate, the baffle is fixedly connected to the fixed rod and the baffle is located on the side of the push plate away from the fixed plate.

[0006] Preferably, the push-pull assembly further includes insert rods and a bonding plate, with multiple insert rods penetrating the fixing plate and multiple insert rods slidably connected to the fixing plate, and multiple insert rods being fixedly connected to the bonding plate.

[0007] Preferably, the push-pull assembly further includes a screw and a turntable, the screw being fixedly connected to the bonding plate, the turntable being rotatably connected to the bonding plate, and the turntable being threadedly connected to the screw.

[0008] A plastic product recycling and crushing device includes a cylinder and a feeding structure. The cylinder has a feeding port, and the push plate and the fixed plate are slidably connected to the inner wall of the cylinder.

[0009] Preferably, a cylinder is fixedly connected to the cylinder, and one end of a connecting rod is fixedly connected to the cylinder, while the other end of the connecting rod is fixedly connected to the push plate.

[0010] Preferably, the cylinder has a sliding hole, and the connecting rod is slidably connected inside the sliding hole.

[0011] Compared with the prior art, the significant advantages of this utility model are:

[0012] Firstly, in this invention, the plastic product to be crushed is placed between the push plate and the fixed plate through the feed inlet. Then, the cylinder is activated, causing the output shaft of the cylinder to move. The movement of the output shaft of the cylinder can drive the connecting rod to move, and the movement of the connecting rod can drive the push plate to move. When the output shaft of the cylinder retracts and drives the push plate to move, the push plate will push the plastic product to one side inside the cylinder. The plastic product will abut against the fixed plate and the insert rod, thereby causing the fixed plate and the bonding plate to move. When the fixed plate abuts against the end of the cylinder, the fixed plate will be fixed. At this time, the push plate continues to push the plastic product. Finally, the plastic product is squeezed between the fixed plate and the push plate, and each insert rod will also assist in crushing the plastic product.

[0013] Secondly, in this invention, since the plastic product is enclosed in the cylinder during the entire crushing process, even if fragments fly out when the plastic product is crushed, they are still inside the cylinder. After the plastic product is crushed, the cylinder can be restarted to extend its output shaft and drive the push plate to move. When the push plate moves to the baffle, the push plate continues to move and will drive the baffle to move. The movement of the baffle will drive the fixed plate to move until the push plate moves to the other end of the cylinder. At this time, the fixed plate will also be at the feed inlet. At this time, the plastic product between the fixed plate and the push plate can be directly taken out from the feed inlet. Attached Figure Description

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides an improved plastic product recycling and crushing device and feeding structure. The technical solution of this utility model is as follows:

[0022] like Figures 1-3 As shown, a plastic product recycling and crushing device and feeding structure include a push-pull assembly 3. The push-pull assembly 3 includes a push plate 31, a fixed rod 32, a fixed plate 33, and a baffle 34. The fixed rod 32 is fixedly connected to the fixed plate 33, and the push plate 31 is slidably connected to the fixed rod 32, with the fixed rod 32 passing through the push plate 31. The baffle 34 is fixedly connected to the fixed rod 32 and is located on the side of the push plate 31 away from the fixed plate 33. When the push plate 31 moves toward the fixed plate 33, the push plate 31 slides on the fixed rod 32. At this time, the push plate 31 moves while the fixed plate 33 remains stationary. When the push plate 31 moves away from the fixed plate 33, it abuts against the baffle 34 and causes the baffle 34 to move together. At this time, the fixed rod 32 moves with the baffle 34, and the fixed plate 33 also moves accordingly. Therefore, by controlling the push plate 31 to move in different directions, the push plate 31 and the fixed plate 33 can be controlled to move closer to each other or move synchronously. When the two are close together, the plastic products between them can be crushed and recycled.

[0023] Furthermore, the push-pull assembly 3 also includes insert rods 35 and bonding plates 36. Multiple insert rods 35 penetrate through the fixing plate 33 and are slidably connected to the fixing plate 33. Multiple insert rods 35 are fixedly connected to the bonding plate 36. By adjusting the position of the bonding plate 36, the length of the insert rods 35 penetrating through the fixing plate 33 can be controlled. The portion of the insert rods 35 penetrating through the fixing plate 33 can be used to help break plastic products.

[0024] Furthermore, the push-pull assembly 3 also includes a screw 37 and a turntable 38. The screw 37 is fixedly connected to the bonding plate 36, and the turntable 38 is rotatably connected to the bonding plate 36. The turntable 38 is threadedly connected to the screw 37. By rotating the turntable 38, the turntable 38 can move on the screw 37. The movement of the turntable 38 on the screw 37 can drive the bonding plate 36 to move, changing the distance between the bonding plate 36 and the fixing plate 33, thereby changing the length of the insert rod 35 penetrating the fixing plate 33.

[0025] A plastic product recycling and crushing device includes a cylinder 1 and a feeding structure. The cylinder 1 has a feeding port 2. A push plate 31 and a fixed plate 33 are slidably connected to the inner wall of the cylinder 1. When crushing plastic products, the push plate 31, the fixed plate 33 and the inner wall of the cylinder 1 can together form a sealed space to prevent plastic product fragments from being ejected.

[0026] Furthermore, a cylinder 4 is fixedly connected to the cylinder 1, and one end of a connecting rod 5 is fixedly connected to the cylinder 4. The other end of the connecting rod 5 is fixedly connected to the push plate 31.

[0027] Furthermore, a sliding hole 6 is provided on the cylinder 1, and the connecting rod 5 is slidably connected to the inside of the sliding hole 6.

[0028] The specific working method is as follows: The plastic product to be crushed is placed between the push plate 31 and the fixed plate 33 through the feed inlet 2. Then, the cylinder 4 is activated, causing its output shaft to move. This movement of the output shaft drives the connecting rod 5, which in turn moves the push plate 31. When the output shaft of the cylinder 4 retracts and moves the push plate 31, the push plate 31 pushes the plastic product towards one side of the cylinder 1. The plastic product then presses against the fixed plate 33 and the insert rod 35, causing the fixed plate 33 and the bonding plate 36 to move. When the fixed plate 33 presses against the end of the cylinder 1, it is fixed in place. At this point, the push plate 31 continues to push the plastic product, ultimately squeezing it against the fixed plate 33 and the push plate. Between 31, each insert rod 35 also assists in crushing the plastic product. Since the plastic product is enclosed in the cylinder 1 during the entire crushing process, even if fragments fly out when the plastic product is crushed, they are still inside the cylinder 1. After the plastic product is crushed, the cylinder 4 can be restarted to extend its output shaft and drive the push plate 31 to move. When the push plate 31 moves to the baffle 34, the push plate 31 continues to move and will drive the baffle 34 to move. The movement of the baffle 34 will drive the fixed plate 33 to move until the push plate 31 moves to the other end of the cylinder 1. At this time, the fixed plate 33 will also be at the feed port 2. At this time, the plastic product between the fixed plate 33 and the push plate 31 can be directly taken out from the feed port 2.
