Description

Technical Field

[0001] This utility model relates to the field of large-diameter PPR pipe fitting production technology, and in particular to a double-shock-absorbing receiving hopper device for receiving large-diameter pipe fittings. Background Technology

[0002] In the automated injection molding production of large-diameter PPR pipe fittings, after the mold is opened and the large-diameter PPR pipe fitting is injection molded, a robot needs to drive the receiving hopper into the injection molding machine to receive the large-diameter pipe fitting. After receiving, the pipe fitting is poured into a cooling tank containing cooling water for cooling. However, due to the large size and weight of the large-diameter pipe fitting, the falling of the pipe fitting during the receiving process can easily cause a large impact on the receiving hopper. This can easily cause deformation and damage to the receiving hopper, and can also easily cause damage or even deformation to the large-diameter pipe fitting, affecting the quality of the finished product. Utility Model Content

[0003] To address the aforementioned problems, this utility model aims to provide a dual-shock-absorbing receiving hopper device for receiving large-diameter pipe fittings, thereby solving the problem of large impact on the receiving hopper during the receiving of large-diameter pipe fittings, which causes damage to the pipe fittings and the receiving hopper.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: A double-shock-absorbing hopper device for receiving large-diameter pipe fittings, comprising a hopper frame and a receiving buffer mechanism, wherein the receiving buffer mechanism comprises a receiving plate, a receiving plate mounting plate and a shock-absorbing spring, wherein the receiving plate is fixed on the receiving plate mounting plate, the receiving plate mounting plate is disposed inside the hopper frame, the receiving plate is located above the bottom plate of the hopper frame, a shock-absorbing spring is disposed between the bottom surface of the receiving plate mounting plate and the bottom plate of the hopper frame, a secondary shock-absorbing pad is disposed on the bottom surface inside the hopper frame, and the receiving plate mounting plate is located above the secondary shock-absorbing pad.

[0005] A guide mechanism is provided between the receiving plate mounting plate and the receiving hopper frame. The guide mechanism includes a linear bearing, a guide shaft and a fixing ring. A linear bearing is provided at the bottom of the receiving hopper frame. A guide shaft passes through the linear bearing. The upper end of the guide shaft is fixed to the bottom of the receiving plate mounting plate. A fixing ring is sleeved on the lower end of the guide shaft. The shock-absorbing spring is sleeved on the outside of the guide shaft.

[0006] Five guiding mechanisms are provided between the receiving plate mounting plate and the receiving hopper frame. The five guiding mechanisms are respectively located at the four corners and the center of the bottom of the receiving hopper frame.

[0007] The receiving hopper frame includes a bottom plate, a back plate, a left side plate, and a right side plate. The bottom edges of the back plate, the left side plate, and the right side plate are fixedly connected to the edge of the bottom plate, and the two sides of the back plate are fixedly connected to the sides of the left side plate and the right side plate, respectively.

[0008] A buffer back plate is provided on the inner side of the back plate, a left buffer plate is provided on the inner side of the left side plate, and a right buffer plate is provided on the inner side of the right side plate.

[0009] The buffer back plate, left buffer plate, and right buffer plate are all high-density foam buffer plates.

[0010] Compared with the prior art, this utility model has the following advantages: It provides multi-layered shock absorption while receiving large-diameter pipe fittings, preventing damage to the pipe fittings and receiving hopper during the receiving process and ensuring the quality of the large-diameter pipe fittings. The buffer plate on the receiving hopper frame provides shock absorption when large-diameter pipe fittings come into contact with each other, effectively preventing scratches on the pipe fitting surface. The shock-absorbing spring provides primary shock absorption after the receiving plate receives the large-diameter pipe fittings and they fall, while the foam secondary shock-absorbing pad provides secondary shock absorption, effectively reducing the impact force generated when the large-diameter pipe fittings fall.

[0017] Combined with appendix Figures 1 to 3As shown, this embodiment discloses a double-shock-absorbing receiving hopper device for receiving large-diameter pipe fittings, including a receiving hopper frame 2, a receiving buffer mechanism, and a guiding mechanism. The receiving buffer mechanism includes a receiving plate 4, a receiving plate mounting plate 7, shock-absorbing springs 11, and secondary shock-absorbing pads 8. The receiving plate 4 is fixed on the receiving plate mounting plate 7, which is located inside the receiving hopper frame 2 and above the bottom plate of the receiving hopper frame 2. Five shock-absorbing springs 11 are arranged between the bottom surface of the receiving plate mounting plate 7 and the bottom plate of the receiving hopper frame 2. A secondary shock-absorbing pad 8 is arranged on the bottom surface inside the receiving hopper frame 2, and the foam secondary shock-absorbing pad 8 is adhered to the bottom surface inside the receiving hopper frame 2 with strong adhesive. The receiving plate 4 is made of polytetrafluoroethylene (PTFE), which is relatively soft and has good self-lubricating properties, ensuring that the pipe fittings slide smoothly into the soaking tank when the receiving hopper pours the pipe fittings into the soaking tank.

[0018] Five guiding mechanisms are provided between the receiving plate mounting plate 7 and the receiving hopper frame 2. These five guiding mechanisms are respectively located at the four corners and the center of the bottom of the receiving hopper frame 2. Each guiding mechanism includes a linear bearing 10, a guide shaft 9, and a fixing ring 3. The linear bearing 10 is located at the bottom of the receiving hopper frame 2, and the guide shaft 9 passes through the linear bearing 10. The upper end of the guide shaft 9 is fixed to the bottom of the receiving plate mounting plate 7, and the lower end of the guide shaft 9 is fitted with a fixing ring 3, which is fixedly connected to the guide shaft 9. The guide shaft 9 passes through a secondary damping pad 8, and a damping spring 11 is fitted around the guide shaft 9 between the receiving plate mounting plate 7 and the receiving hopper frame 2 to provide damping for the receiving plate mounting plate 7. The receiving plate 4 is connected and fixed to the receiving plate mounting plate 7 by six hexagonal socket head cap screws.

[0019] The receiving hopper frame 2 includes a bottom plate, a back plate, a left side plate, and a right side plate. The bottom edges of the back plate, left side plate, and right side plate are fixedly connected to the edge of the bottom plate, and the two sides of the back plate are fixedly connected to the sides of the left side plate and the right side plate, respectively. A buffer back plate 1 is provided on the inner side of the back plate, a left buffer plate 6 is provided on the inner side of the left side plate, and a right buffer plate 5 is provided on the inner side of the right side plate. The buffer back plate 1, the left buffer plate 6, and the right buffer plate 5 are all high-density foam buffer plates, which are relatively soft and can provide a certain degree of shock absorption when large-diameter pipes come into contact with them, while effectively preventing scratches on the surface of the pipes. The high-density foam buffer plates are adhered to the receiving hopper frame with strong adhesive. During the descent of large-diameter pipe fittings, they inevitably come into contact with the left and right sides and back of the receiving hopper frame 2. During this contact, the high-density foam cushioning backplate 1, the left high-density foam cushioning plate 6, and the right high-density foam cushioning plate 5 effectively prevent damage and deformation to the pipe fitting surface when they collide with the receiving hopper frame 2. The left side of the receiving hopper frame 2 has eight threaded holes for connection and fixation with the material handling robot.

[0020] The specific implementation process of this utility model device in the production process is as follows: First, the receiving hopper frame 2 is fixed to the material handling robot through the threaded hole on the left side. Then, the device is started to connect with the injection molding machine and the soaking tank to begin production. When the injection molding of the large-diameter pipe is completed and the injection molding machine opens the mold, the material handling robot drives the receiving hopper frame 2 and the components above it to extend into the mold inside the injection molding machine. Then, the ejector pin of the injection molding machine moves to push the large-diameter pipe out of the mold. After being pushed out, the large-diameter pipe falls due to gravity and first collides with the receiving plate 4. The receiving plate 4, together with the receiving plate mounting plate 7, moves downward under the impact of the large-diameter pipe. During the movement, the guide shaft 9 and the linear bearing 10 provide good guidance for the receiving plate 4 and the receiving plate mounting plate 7, while the shock-absorbing spring 11 provides a shock-absorbing effect, greatly reducing the impact force of the falling large-diameter pipe. As the receiving plate 4 and the receiving plate mounting plate 7 continue to move downwards, the receiving plate mounting plate 7 begins to contact the secondary foam cushioning pad 8, and the impact force of the large-diameter pipe is further reduced by the cushioning of the secondary foam cushioning pad 8. Finally, the large-diameter pipe falls smoothly onto the receiving plate 4. The high-density foam backing plate 1, the left high-density foam cushioning plate 6, and the right high-density foam cushioning plate 5 on the receiving hopper frame 2 can effectively prevent damage and deformation of the pipe surface when the large-diameter pipe touches the receiving hopper frame 2. Then, the picking robot moves the receiving hopper frame 2 and the components on it, along with the large-diameter pipe that has been picked up, to the top of the soaking tank. Then, the picking robot rotates the receiving hopper frame 2 at a certain angle, and the large-diameter pipe slides along the receiving plate 4 into the soaking tank for soaking and cooling. Finally, the picking robot moves the receiving hopper frame 2 and the components on it back to the standby point to wait for the injection molding of the next large-diameter pipe and the mold opening of the injection molding machine. This process is repeated until the device completes its operation.

[0021] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
