Description

Technical Field

[0001] The utility model relates to the technical field of dust-free feeding of modifiers, in particular to a powdery raw material feeding device for a dust-free modifier production line. Background Art

[0002] As a highly effective alternative material, modifiers have been widely used in a variety of applications, including soft leather, sports flooring, hard flooring, and PVC pipes. Their primary purpose is to achieve cost savings by reducing PVC usage while ensuring consistent product quality and performance. However, the preparation of modifiers involves unpacking and loading raw materials. These raw materials must be fed into a specialized mixing device and thoroughly mixed with other ingredients in a predetermined ratio to create the final product.

[0003] Currently, the production process for modifiers typically relies on a variety of equipment dispersed throughout the workshop for feeding, mixing, weighing, and packaging. Because the main raw material for modifiers is in powder form, dust is easily generated during material transportation. This not only pollutes the workshop environment but also poses a health risk to workers. Furthermore, dust intrusion can accelerate wear of mechanical equipment and even cause equipment failure.

[0004] To address these issues in the existing technology, the inventors proposed a dust-free modifier production line. The core of this production line lies in the use of a precisely designed negative pressure conveying piping system to connect all production equipment. During the loading phase, a dedicated silo is used to store powdered raw materials, ensuring that the raw materials can be safely and efficiently introduced into subsequent processes when needed.

[0005] Despite this, the feeding point of powdery raw materials is still a potential source of dust emission. Therefore, this application further focuses on the design improvement of the feeding device to solve the problem of dust emission and provide guarantees for a cleaner, more environmentally friendly and safer production environment.

[0006] In view of this, the inventor specially designed a powdery raw material feeding device for a dust-free modifier production line, which led to the creation of this case. Utility Model Content

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] See also Figures 1 to 5 , which is a powdery raw material feeding device for a dust-free modifier production line as the best embodiment of the present invention, includes: a feeding assembly 10, a support frame 20, a hoisting assembly 30, a covering assembly 40 and a lifting assembly 50, wherein:

[0036] The upper end of the feeding assembly 10 forms a feeding hopper 11 for receiving the powdery raw materials. The lower end of the feeding hopper 11 is connected to a negative pressure conveying pipe system 13 to achieve the feeding of the powdery raw materials.

[0037] In this embodiment, the loading assembly 10 includes four supporting legs 12 distributed in a matrix shape, and the loading hopper 11 is arranged at the upper ends of the four supporting legs 12. The inner side thereof forms a funnel-shaped aggregate trough with an open upper end. The lower end of the aggregate trough is connected to the negative pressure conveying pipeline system 13 in the workshop. Through the subsequent corresponding negative pressure generating equipment, the powdery raw materials in the aggregate trough are sucked into the subsequent storage space such as the silo for storage.

[0038] In addition, in order to facilitate the breaking of the packaging bags of the powdery raw materials so that the powdery raw materials in the packaging bags can fall smoothly into the upper hopper 11, a blade or other bag-breaking structure for cutting the packaging bags (not shown in the figure) can be provided in the upper hopper 11. This is a prior art and will not be described in detail here.

[0039] The support frame 20 includes four support columns 21 provided on the periphery of the loading assembly 10 and a top frame 22 for connecting the tops of the four support columns 21;

[0040] In this embodiment, the support frame 20 is distributed around the upper hopper 11, and the height of the support column 21 is higher than the height of the upper hopper 11, so as to form an integral support frame 20 around the upper hopper 11, which is convenient for installing the corresponding lifting components 30 and automatically lifting the powdery raw materials.

[0041] The hoisting assembly 30 includes a hoisting rail 31 provided on the top frame 22, a hoisting mechanism 32 that can slide along the hoisting rail 31, and a drive motor (not shown) for driving the hoisting mechanism 32. The hoisting mechanism 32 is used to hoist the packaging bag carrying the powdery raw material.

[0042] In this embodiment, the hanging rail 31 is used to provide a moving path for the lifting mechanism 32. Driven by the driving motor, the lifting mechanism 32 can move along the path where the hanging rail 31 is located, and the lifting mechanism 32 includes a liftable hook and a lifting motor (not shown in the figure) that drives the hook to lift and lower. Therefore, through the above structure, the packaging bag of the powdery raw material of the modifier can be conveniently lifted from the bottom surface to the upper hopper 11, which is convenient for automatic loading.

[0043] The covering assembly 40 includes a covering film bag 41 and a manual control structure 42. The covering film bag 41 is cylindrical with two ends open. The lower end opening of the covering film bag 41 is fixed to the outside of the upper hopper 11 so that the upper hopper 11 covers its relatively closed interior. The manual control structure 42 is used to close or open the upper end opening of the covering film bag 41.

[0044] The lifting assembly 50 is used to drive the upper opening of the covering film bag 41 to rise or fall.

[0045] Specifically, the lifting assembly 50 includes a lifting frame 51, a first control rope 52, a first guide member 53 and a control member 54. A through opening (not marked in the figure) is formed in the middle of the lifting frame 51 opposite to the upper hopper 11. Four first control ropes 52 are provided and one end of each is fixed to the corner position of the upper end surface of the lifting frame 51. The first guide member 53 is provided on four support columns 21 and is used to roll and guide the first control rope 52. The control member 54 is provided on one of the support columns 21 and is used to retract or release the first control rope 52. The other ends of the four first control ropes 52 pass through the first guide member 53 and are gathered at the control member 54 to enable a transmission connection between the control member 54 and the lifting frame 51.

[0046] Furthermore, the two first control ropes 52 located on the same side of the lifting frame 51 are converged on the same second control rope 55, and a second guide member 56 is provided at the upper end of the support column 21 where the control member 54 is located. The two second control ropes 55 pass through the second guide member 56 and are converged on the same third control rope 57. The other end of the third control rope 57 is connected to the control member 54.

[0047] In this embodiment, the first guide member 53 and the second guide member 56 are both guide rollers, and are both provided with two annular guide grooves (not shown in the figure). The two first control ropes 52 are respectively passed around one of the guide grooves, thereby forming a guide for the first control ropes 52. The ends of the two first control ropes 52 are fixed on the same side of the same connecting piece 60, and the other side of the connecting piece 60 is connected to one end of the second control rope 55. After the other ends of the two second control ropes 55 pass around the two guide grooves of the second guide member 56, they are jointly fixed on the same side of another connecting piece 60. The other side of the connecting piece 60 is fixedly connected to the third control rope 57. Therefore, by pulling the third control rope 57, the two second control ropes 55 can be controlled to move synchronously at the same time, so that the four first control ropes 52 connected to the two second control ropes 55 are pulled synchronously, and finally the lifting frame 51 is smoothly raised or lowered.

[0048] The above-mentioned structural setting enables the lifting frame 51 to be smoothly raised and lowered through a third control rope 57, so that the lifting frame 51 is moved above the packaging bag according to the size of the packaging bag and the actual unloading position, so that the upper end opening of the covering film bag 41 is located above the packaging bag, and finally the packaging bag is located in the closed area formed by the covering film bag 41 and the loading hopper 11, thereby realizing flexible adjustment of the covering film bag 41 and adapting to the loading of packaging bags of different sizes.

[0049] In addition, by setting two adjacent first control ropes 52 on the same side of the lifting frame 51 and leading them out, the four first control ropes 52 can be passed around the two sides of the lifting frame 51 to avoid crossing above the lifting frame 51, thereby exposing the area at the upper end of the lifting frame 51 and avoiding interference with the lifting process of the packaging bags.

[0050] Preferably, the control member 54 includes a winding box 541 and a winding crank 542. A winding shaft (not shown in the figure) is rotatably provided in the winding box 541. The winding crank 542 is transmission-connected to the winding shaft to drive it to rotate synchronously. The end of the third control rope 57 is fixed on the winding shaft.

[0051] In this embodiment, in order to achieve precise control of the third control rope 57, a locking structure (not shown in the figure) for locking the winding shaft is also provided on the winding box 541, such as a latch, so that after the lifting frame 51 is lifted to a suitable position by the winding crank 542, its position can be fixed, thereby improving its stability during the loading process of the powdery raw material packaging bag.

[0052] Preferably, an elastic rope 70 is wrapped around the edge of the upper opening of the covering film bag 41 to achieve automatic closing in its natural state. A plurality of first pull ropes 421 are provided at the upper opening of the covering film bag 41. The plurality of first pull ropes 421 are guided by the lifting frame 51 and then gathered into the same second pull rope 422. One end of the second pull rope 422 can be detachably fixed to one side of the control component 54.

[0053] In this embodiment, the elastic rope 70 is a rubber elastic rope 70, and the upper end opening of the covering film bag 41 is rolled back to form an annular installation area (not marked in the figure). The rubber elastic rope 70 is inserted into the installation area so that the upper end opening of the covering film bag 41 can be automatically contracted. The rubber elastic rope 70 can be opened by pulling the upper end opening by the manual control structure 42, and after the controlled structure is released, it can automatically contract, thereby facilitating the control of the upper end opening of the covering film bag 41 to be opened or closed, so that the lifting mechanism 32 can lift the packaging bag in and out of the coverage range of the covering film bag 41.

[0054] Preferably, the lifting frame 51 is square and has an inner side formed with a mounting groove 511 distributed around its inner wall. The four corners of the mounting groove 511 are provided with third guide members 512 for rolling and guiding the second pull rope 422 .

[0055] Furthermore, the two second pull ropes 422 located on the same side of the lifting frame 51 are merged into the same third pull rope 423, and the two third pull ropes 423 are merged into the same second pull rope 422. An outlet hole 513 is provided through the installation groove 511, and the movable end of the second pull rope 422 passes through the outlet hole 513 and is led out to one side of the control component 54.

[0056] In this embodiment, the third guide member 512 is a guide roller and has two guide grooves (not marked in the figure). The two second pull ropes 422 pass through the two guide grooves of the same guide roller and are connected to the same third pull rope 423 through the connecting piece 60. After the two third pull ropes 423 pass out of the outlet hole 513, they are fixedly connected to the second pull rope 422 through another connecting piece 60, thereby achieving the purpose of aggregating the four first pull ropes 421 into one second pull rope 422 for control, and in this embodiment, the first stretch is evenly distributed on the edge of the annular area formed by the elastic rope 70, so that when the second pull rope 422 is pulled, the upper end opening of the covering film bag 41 can be evenly pulled open, thereby facilitating the opening of the upper end opening of the covering film bag 41.

[0057] Similar to the above structure, in this embodiment, two adjacent first pull ropes 421 are arranged on the same side of the lifting frame 51, so that the four first pull ropes 421 are evenly distributed on both sides of the lifting frame 51, avoiding them from crossing in the middle area of ​​the lifting frame 51, thereby exposing the middle area of ​​the lifting frame 51 and avoiding interference with the lifting process of the packaging bags.

[0058] Preferably, a pull ring 424 is provided at the movable end of the second pull rope 422 , and a limiting rod (not shown in the figure) for limiting the pull ring 424 is provided on the side wall of the support column 21 , and the pull ring 424 is hung on the pull rod.

[0059] The pull ring 424 and the limiting rod can facilitate the user to control the opening and closing of the upper end opening of the covering film bag 41 .

[0060] Preferably, a flexible contact member 80 is provided around the edge of the top of the outer peripheral side of the upper hopper 11 , and an arc-shaped transition surface (not marked in the figure) is provided at the outer corner of the flexible contact member 80 .

[0061] In this embodiment, the flexible contact member 80 is a rubber member or a silicone member. Through the setting of the arc-shaped transition surface, the inner wall surface of the covering film bag 41 and the flexible contact member 80 can be in smooth contact, thereby preventing the sharp edges of the upper hopper 11 or the support leg 12 from scratching the covering film bag 41 when the covering film bag 41 moves up and down with the lifting frame 51, thereby extending the service life of the covering film bag 41.

[0062] Preferably, the covering film bag 41 is a transparent bag.

[0063] This makes it easy to observe the internal loading situation and to judge whether the dust has been sufficiently settled, so that the operator can take out the packaging bag.

[0064] In particular, in this embodiment, the contracted position of the upper opening of the covering film bag 41 can also be positioned at the height of the middle of the packaging bag, so that the covering film bag 41 contracts and fits the packaging bag.

[0065] In this embodiment, the lower opening of the covering film bag 41 surrounds the upper hopper 11 and the peripheral sides of the supporting legs 12 and is fixed thereto, so that the lower opening forms a closed area to prevent dust from leaking out.

[0066] The beneficial effects of the utility model are as follows:

[0067] The present invention utilizes a covering film bag 41 to cover the surrounding area of ​​the loading hopper 11. When loading powdery raw materials, the upper opening of the covering film bag 41 is opened by a manual control mechanism 42, allowing the lifting mechanism 32 to smoothly hoist the powdery raw material packaging bag into the covering film bag 41, ensuring that it reaches the unloading area of ​​the loading hopper 11. After loading is completed, the upper opening of the covering film bag 41 shrinks, forming a temporary and relatively closed area. This effectively blocks dust emitted during the unloading process, minimizing dust leakage into the workshop environment, thereby maintaining a clean workshop environment and protecting the physical and mental health of operators.

[0068] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
