Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and more specifically, to a pipeline conveying device for a mixing machine. Background Technology

[0002] To achieve certain performance characteristics of the product, it is necessary to mix various different powder materials together. During mass production, large mixers are used to mix the different powder materials as needed to provide large quantities of raw materials. For ease of feeding, large mixers are typically configured as two- or multi-layer mixing systems. The mixer is located on the first layer, with the second and upper layers divided into interconnected feeding stations. Each feeding station is equipped with a pipeline conveying device, which includes a conical hopper and a pipe connected to the hopper. The other end of the pipe connects to the mixer. During feeding, workers lift the bagged powder and pour it entirely into the conical hopper, repeating this process multiple times as needed.

[0003] The existing conical hopper has a small inner diameter at the outlet. When a bag of powder is poured into the conical hopper all at once and quickly, the powder will accumulate and block the outlet of the conical hopper and cannot fall into the pipe (similar to using a sieve to hold flour). Therefore, the staff needs to stop feeding and use a stick to clear the blockage, resulting in low work efficiency when feeding. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a pipeline conveying device for a mixing machine, comprising a conical hopper and a clearing mechanism. A connecting pipe is fixedly provided at the outlet of the conical hopper, and the connecting pipe is adapted to connect to a discharge pipe to allow material to enter the mixing machine. The clearing mechanism is disposed on the connecting pipe, and a control switch for controlling the operation of the clearing mechanism is provided at the conical hopper. The clearing mechanism includes a clearing rod, a connecting plate, and a driving component. The clearing rod is inserted into the connecting pipe, and the top end of the clearing rod is located inside the conical hopper. One end of the connecting plate is fixedly connected to the clearing rod, and the other end extends out of the connecting pipe and is located outside the connecting pipe and connected to the driving component. The driving component is adapted to drive the connecting plate to move the clearing rod up and down reciprocatingly.

[0005] Optionally, the outer wall of the connecting pipe is provided with a lifting groove, and the end of the connecting plate away from the unblocking rod is inserted into the lifting groove and can move up and down in the lifting groove.

[0006] Optionally, a silicone sheet is provided on the wall of the lifting groove to cover the lifting groove. The silicone sheet has a long slit, the extension direction of which is consistent with the lifting direction of the connecting plate. The end of the connecting plate away from the unblocking rod is interference-fitted into the long slit.

[0007] Optionally, a Z-shaped plate is fixedly connected to the end of the connecting plate away from the unblocking rod, and the driving member is located on the side of the Z-shaped plate away from the connecting plate. The driving member is connected to the Z-shaped plate to drive the Z-shaped plate to rise and fall.

[0008] Optionally, the Z-shaped plate is provided with a slot, and the end of the connecting plate away from the unblocking rod is inserted into the slot. Bolts are provided on the outer wall of the Z-shaped plate, and the connecting plate is connected to the Z-shaped plate by the bolts.

[0009] Optionally, a support seat is provided on one side of the conical hopper, the support seat being suitable for placement when bagged powder is fed.

[0010] Optionally, the mixing machine's pipeline conveying device further includes a top pipe located above the conical hopper, the top pipe being adapted to communicate with an upper conveying pipeline and the conical hopper.

[0011] Optionally, the top pipe is provided with a corrugated section, and the end of the top pipe near the conical hopper can be adjusted in height and telescopically via the corrugated section.

[0012] Optionally, the pipeline conveying device for the mixer also includes a protective cabinet, the conical hopper being disposed inside the protective cabinet, and a cabinet door being hinged to one side of the protective cabinet.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] 1. When adding material into the conical hopper, the unblocking mechanism is activated by the control switch. The drive unit will drive the unblocking rod to move up and down in the connecting pipe and the conical hopper to unblock the material, so that the powder can flow smoothly into the conveying pipe. At the same time, the staff does not need to stop the feeding work to unblock, thus improving work efficiency.

[0015] 2. The drive unit is located outside the conical hopper, which does not occupy a large space inside the conical hopper, ensuring that the material powder can flow normally to achieve feeding;

[0016] 3. Because the silicone sheet itself has good elasticity, the position of the silicone sheet becomes larger after the connecting plate is inserted into the long gap, while the gaps at other positions remain small. When the connecting plate moves up and down and the powder material is fed through the connecting pipe, it is not easy for it to leak from the long gap of the silicone sheet.

[0017] 4. The top pipe allows materials from the upper floor to flow into the conical funnel, while the corrugated section of the top pipe allows the bottom of the top pipe to be adjusted to any position and length.

[0018] 5. The protective cabinet can protect the conical funnel, making it less likely for insects to enter the mixer through the conical funnel and affect the materials when the machine is not in operation at night. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This utility model provides a pipeline conveying device for a mixer, see reference. Figure 1 and Figure 2The mixing machine's pipeline conveying device includes a conical hopper 1, a clearing mechanism 2, a top pipe 3, and a protective cabinet 4. Both the conical hopper 1 and the clearing mechanism 2 are located inside the protective cabinet 4. The protective cabinet 4 is positioned so that, when the machine is not in operation at night, insects are less likely to enter the mixing machine through the conical hopper and affect the materials. The clearing mechanism 2 can clear the discharge port of the conical hopper 1, preventing powdered materials from accumulating and clogging the discharge port. The top pipe 3 allows materials from the upper floor to flow into the conical hopper.

[0028] Reference Figure 1 and Figure 2 The conical hopper 1 is designed with its larger inner diameter end as the feed inlet and its smaller inner diameter end as the discharge outlet. The feed inlet of the conical hopper 1 faces upwards, and a connecting pipe 11 is fixedly installed at the discharge outlet of the conical hopper 1. The connecting pipe 11 is adapted to connect to the discharge pipe on the mixer to allow material to enter the mixer. A control switch (not shown in the figure) is provided at the conical hopper 1 to control the operation of the unblocking mechanism 2. The control switch can be pressed when unblocking the discharge outlet of the conical hopper 1 is required.

[0029] Multiple support legs 12 are welded to the bottom of the conical hopper 1. The multiple support legs 12 are arranged circumferentially at intervals at the bottom of the conical hopper 1, thereby providing support for the conical hopper 1.

[0030] Reference Figure 2 and Figure 4 In this embodiment, the unblocking mechanism 2 is preferably mounted on the connecting pipe 11. The unblocking mechanism 2 includes an unblocking rod 21, a connecting plate 22, and a driving component 23. The unblocking rod 21 is inserted into the connecting pipe 11, with its top end located inside the conical hopper 1. One end of the connecting plate 22 is welded and fixed to the outer wall of the unblocking rod 21, and the other end extends out of the connecting pipe 11 and is located outside the connecting pipe 11. A Z-shaped plate 24 is fixedly connected to the end of the connecting plate 22 away from the unblocking rod 21. The Z-shaped plate 24 has a slot 241, and the end of the connecting plate 22 away from the unblocking rod 21 is inserted into the slot 241. Bolts are provided on the outer wall of the Z-shaped plate 24, and the connecting plate 22 is limited to the slot 241 and fixedly connected to the Z-shaped plate 24 by the bolts. The driving component 23 is located on the side of the Z-shaped plate 24 away from the connecting plate 22. The driving component 23 is connected to the Z-shaped plate 24 to drive the Z-shaped plate 24 to rise and fall. The driving component 23 has a larger installation space in the vertical direction through the Z-shaped plate 24. After the Z-shaped plate 24 rises and falls, it drives the connecting plate 22 to drive the unblocking rod 21 to reciprocate and rise and fall to achieve unblocking. In this embodiment, the driving component 23 is preferably a cylinder.

[0031] Combination Figure 2 Reference Figure 3 and Figure 4The outer wall of the connecting pipe 11 is provided with a lifting groove 13, which is connected to the inside of the connecting pipe 11 and extends vertically. The end of the connecting plate 22 away from the unblocking column is inserted into the lifting groove 13 and can move up and down within the lifting groove 13.

[0032] A silicone sheet 14 is fixedly installed on the wall of the lifting groove 13, covering the entire lifting groove 13. A long slit is formed on the silicone sheet 14, extending in the same direction as the lifting direction of the connecting plate 22. One end of the connecting plate 22, which connects to the Z-shaped plate 24, passes through the long slit, allowing the connecting plate 22 to move up and down within it. Because the silicone sheet 14 has good elasticity, after the connecting plate 22 is inserted into the long slit, the area of ​​the silicone sheet 14 at that point becomes larger, while the gaps at other locations remain relatively small. This prevents powder material from leaking out of the long slit of the silicone sheet 14 during the lifting and lowering movement of the connecting plate 22.

[0033] Reference Figure 1 and Figure 2 The protective cabinet 4 has a hinged door 41 on one side, which can be closed when the conical hopper 1 is not in use. The conical hopper 1 has a support seat 15 on the side near the door 41. The support seat 15 is located inside the protective cabinet 4. When the staff moves bagged powder into the conical hopper 1, they can place the bag on the support seat 15. Compared with the previous method of manually carrying the whole bag of powder into the conical hopper 1, the setting of the support seat 15 can reduce the labor intensity of the staff to a certain extent.

[0034] The top pipe 3 is located above the conical hopper 1. The top end of the top pipe 3 passes through the top of the protective cabinet 4 and connects to the upper floor conveying pipe. The top pipe 3 is connected to the conical hopper 1, allowing material from the upper floor to flow into the conical hopper and then into the mixer. The top pipe 3 is equipped with a corrugated section 31. The end of the top pipe 3 near the conical hopper 1 can be raised, lowered, extended, and adjusted via the corrugated section 31. When no material is being discharged from the upper floor, the length of the top pipe 3 can be shortened by the corrugated section 31 to make way, allowing the bottom end of the top pipe 3 to detach from the conical hopper 1, so that powder material can be poured into the conical hopper 1.

[0035] The implementation principle of the pipeline conveying device for a mixing machine in this embodiment is as follows: When adding material into the conical hopper 1, the unblocking mechanism 2 is activated by the control switch. The driving component 23 drives the unblocking rod 21 to move up and down reciprocally within the connecting pipe 11 and the conical hopper 1 to unblock the material, allowing the powder to flow smoothly into the conveying pipeline. This eliminates the need for workers to stop adding material to unblock the pipe. When the connecting plate 22 moves up and down, the silicone sheet 14 has good elasticity. Therefore, after the connecting plate 22 is inserted into the long gap, the position of the silicone sheet 14 at that point becomes larger, while the gaps at other positions remain small, preventing powder from leaking out of the long gap of the silicone sheet 14.

[0036] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
