Technical Field
[0001] This utility model relates to the technical field of plastic pipe production equipment, specifically to a device for reusing start-up waste from plastic pipe production. Background Technology
[0002] Currently, waste control is a crucial aspect of plastic pipe production. During factory production, a significant proportion of waste is generated during operation, and excessive waste rates and wasted raw materials are major obstacles to improving production efficiency and reducing costs. Nowadays, waste recycling in the workshop requires waste grading and rejection, followed by weighing, crushing, and recycling.
[0003] The feeding of waste materials is done manually using methods such as hopper feeding, resulting in slow feeding, low crushing speed, poor efficiency, and high labor costs. With high production line uptime in the workshop, the process of recycling and reusing waste materials is complex and lengthy. Furthermore, the waste generated during operation is prone to falling to the ground and contaminating the environment, creating unrecoverable waste that increases production costs and reduces efficiency.

The four uprights 2 are arranged in a square pattern, and their lower ends are connected to the four corners of the base plate 1. The reinforcing vertical plates 3 are located between two adjacent uprights 2. The two vertical edges of the reinforcing vertical plates 3 are connected to the corresponding two uprights 1, and the bottom of the reinforcing vertical plates 3 is connected to the bottom. The reinforcing vertical plates 3 and the two uprights 2 connected to them are integrally formed.

The lifting platform 4 is square and is located within the space enclosed by the base plate 1 and four columns 2. First baffle plates 5 are symmetrically provided on the two width-direction edges of the lifting platform 4. The function of the first baffle plates 5 is to prevent the waste material on the lifting platform 4 from falling to the ground from the two width-direction edges of the lifting platform 4 during the pushing process.
[0023] The lifting drive mechanism includes a lifting motor 6, a driving gear 7, a driven gear 8, a ball bearing nut seat 9, a guide rod 10, and a lead screw 11. The guide rod 10 and lead screw 11 are symmetrically arranged relative to the lifting platform 4, and both are vertically positioned. The lower end of the lead screw 11 is rotatably connected to one side of the base plate 1 via a bearing, and the upper end of the lead screw 11 is connected to the center of one side edge of the lifting platform 4 in the width direction via a sliding sleeve. The lower end of the guide rod 10 is fixedly connected to the other side of the base plate 1. The ball bearing nut seat 9 is sleeved on the lead screw 11 and fixedly connected to the center of the other side edge of the lifting platform 4 in the width direction. The lifting motor 6 is fixedly installed on the ground, the driving gear 7 is fixedly sleeved on the output shaft of the lifting motor 6, and the driven gear 8 is fixedly sleeved on the lower part of the lead screw 11.
[0024] When the lifting motor 6 is working, the lifting motor 6 drives the drive gear 7 to rotate, the drive gear 7 drives the driven gear 8 to rotate, the driven gear 8 drives the lead screw 11 to rotate, and the lead screw 11 drives the ball nut seat 9 to rise and fall, thereby driving the lifting platform 4 to rise and fall.
[0025] The material pushing mechanism includes a material pushing plate 12, a material unloading plate 13, and a material pushing drive mechanism. The material pushing drive mechanism includes an electric push rod 16 and a motor bracket. The motor bracket includes a supporting vertical plate 23, a supporting horizontal plate 14, and a top support plate 15. Both the supporting horizontal plate 14 and the supporting vertical plate 23 are square. The bottom of the supporting vertical plate 23 is connected to the side wall of the supporting horizontal plate 14 along its length, forming an L-shaped structure. The top support plate 15 is triangular. The supporting horizontal plate 14 is located outside the space enclosed by the base plate 1 and the four columns 2. One edge of the supporting horizontal plate 14 along its length is connected to the top of the reinforcing vertical plate 3. One right-angled edge of the top support plate 15 is connected to the middle position of the reinforcing vertical plate 3, and the other right-angled edge of the top support plate 15 is connected to the middle position of the supporting horizontal plate 14. The top support plate 15 is perpendicular to both the reinforcing vertical plate 3 and the supporting horizontal plate 14. The material pushing plate 12 is vertically arranged and located directly above the lifting platform 4. The electric push rod 16 is fixed to the support vertical plate 23. The telescopic rod of the electric push rod 16 is connected to the push plate 12, and the telescopic rod of the electric push rod 16 is perpendicular to the push plate 12.
[0026] The feeding plate 13 is square and horizontally positioned. It is located outside the space enclosed by the base plate 1 and four uprights 2, with one length edge connected to two adjacent uprights 2. Two second baffles 20 are provided along the width edges of the feeding plate 13. These baffles prevent the waste material from falling to the ground from the edges of the feeding plate 13 during the feeding process. An arc-shaped guide plate 22 is located on the feeding plate 13, facing away from the pusher plate 12. The guide plate 22 is positioned directly above the feed inlet of the crusher 18, facilitating the entry of waste material into the crusher 18.
[0027] A limit block 17 is connected at the midpoint of the edge along the length of the connection between the supporting horizontal plate 14 and the reinforcing vertical plate 3. A contact sensor 21 is provided at the bottom of the limit block 17. When the lifting platform 4 rises to contact the contact sensor 21, the lifting platform 4 stops rising. At this time, the lifting platform 4 is located between the supporting horizontal plate and the unloading plate 13, and the top surface of the lifting platform 4 is flush with the top surface of the unloading plate 13.
[0028] The crusher 18 and the screw feeder 19 are respectively installed on the ground by brackets, and the discharge port of the crusher 18 is sealed to the feed hopper of the screw feeder 19.
[0029] After the machine generates waste material upon startup, it is placed on the lifting platform 4 after a short cooling period. When the waste material on the lifting platform 4 accumulates to a certain amount, the lifting motor 6 is turned on, and the lifting platform 4 begins to rise. When the lifting platform 4 rises to be level with the discharge plate 13, the electric push rod 16 is activated, pushing the pusher plate 12 towards the crusher 18, pushing the waste material from the lifting platform 4 onto the discharge plate 13, until the waste material is pushed off the discharge plate 13 and falls into the crusher 18 for crushing. After crushing, the waste material is sent to the discharge section via the screw feeder 19, where it is reheated, melted, filtered, and recycled.
