Abstract
Description
Technical Field
[0001] This utility model relates to a kneader, specifically, to a kneader that can quickly feed materials. Background Technology
[0002] In the chemical, polymer, food and engineering plastics processing industries, kneaders are often used to process materials so that semi-dry or rubbery viscous plastic materials can react quickly to obtain a homogeneous mixture. When the kneader is mixing the mixture, a material conveying device is needed to automatically feed the material into the kneader to achieve rapid feeding.
[0003] The utility model with authorization announcement number CN219404924U provides a feeding device for a kneader. By setting up an inlet, a conveying pipe, a kneader body, a fixing ring, a connecting block, a positioning block, an adjustment mechanism, and a positioning mechanism, the conveying pipe can be quickly fixed on the kneader by adjusting the adjustment mechanism and the positioning mechanism. Then, when the kneader is in production and processing, the worker can quickly feed materials into the kneader through the conveying pipe.
[0004] When the kneader is temporarily shut down for storage, the operator needs to separate the conveyor pipe from the kneader for separate storage. However, the above-mentioned patented technology has significant drawbacks: after the conveyor pipe is disassembled from the kneader's feed pipe, the feed port will be completely exposed to the open environment. If there are materials left inside the equipment that have not been cleaned in time (especially for special materials such as silica gel and resin that are easily oxidized, moisture-absorbing, or contaminated), dust, moisture, and other pollutants in the outside air will enter the equipment cavity through the open pipe, causing the residual materials inside to undergo quality changes such as oxidation, moisture absorption, or contamination. In addition, the exposed materials are prone to drying and clumping under environmental conditions, which not only directly affects the material processing efficiency when the equipment is restarted, but may also cause mechanical failure due to abnormal load on the mixing system caused by the clumped materials. It is worth noting that even if the operator uses a cover to seal it in time, suspended particles raised during the disassembly process may still enter the equipment through the temporarily exposed pipe. This potential contamination risk will still pose a quality hazard to subsequent production. Utility Model Content
[0005] The purpose of this invention is to provide a kneader that can quickly feed materials, so as to solve the problems mentioned in the background art above:
[0006] When the conveying pipe is removed from the feed pipe of the kneader, the feed port will be completely exposed to the open environment. Dust, moisture and other pollutants in the outside air will enter the equipment cavity through the open pipe, causing the residual material inside the kneader to undergo quality changes such as oxidation, moisture absorption or contamination.
[0007] To achieve the above objectives, the present invention provides a kneader for rapid material feeding, comprising a kneader body, a feed pipe fixed to the upper side wall of the kneader body, a conveying pipe above the feed pipe, the conveying pipe comprising a pipe body, a turntable rotatably mounted on one side of the feed pipe, a connecting groove being formed near the edge of the turntable, and a side groove being formed on the side wall of the feed pipe corresponding to the turntable, with other positions of the turntable rotatably disposed inside the side grooves, a linkage mechanism being provided on the upper side of the turntable, and a locking mechanism being provided on the feed pipe. When the pipe body moves directly above the feed pipe and connects with the feed pipe, the locking mechanism positions and locks the pipe body, while the pipe body drives the turntable to rotate through the linkage mechanism, causing the connecting groove to rotate to a position connecting with the internal channel of the feed pipe, thus opening the feed pipe.
[0008] As a further improvement to this technical solution, the locking mechanism includes a tray fixedly mounted on the outer circumference of the feed pipe. The tray has symmetrical movable slots on both sides. Two T-shaped sliders are symmetrically fixed on the side wall of the pipe body. When the pipe body is connected to the feed pipe, the lower end of the pipe body is located inside the tray. The two T-shaped sliders are slidably mounted inside the two movable slots. The T-shaped sliders and the movable slots cooperate to prevent the pipe body 21 from rotating around its own axis and restrict one degree of freedom of the pipe body in the horizontal direction.
[0009] As a further improvement to this technical solution, the locking mechanism also includes an end plate disposed below the tray. A wedge is fixedly disposed on the upper side wall of the end plate. The upper end of the wedge slides through the tray and extends outward. The side of the upper end face of the wedge away from the feed pipe is set as an inclined surface. When the pipe body is connected to the feed pipe, the wedge contacts the outer circumferential wall of the pipe body. The wedge and the tray cooperate to restrict another degree of freedom of the pipe body in the horizontal direction.
[0010] As a further improvement to this technical solution, the locking mechanism also includes two guide rods vertically arranged on both sides of the wedge. The upper end of the guide rod is fixedly arranged on the lower side wall of the tray, and the lower end of the guide rod slides through the end plate and extends outward. A spring sleeved on the guide rod is fixed between the end plate and the tray. The spring drives the end plate to approach the tray, so that the upper end of the wedge is stable inside the tray when it is not under downward pressure.
[0011] As a further improvement to this technical solution, the linkage mechanism includes a gear coaxially fixed to the upper side wall of the turntable via a spline, and a rack is fixedly installed on the side wall of the pipe body via a bracket. When the lower end of the pipe body is located inside the tray, the rack and the gear mesh, thereby rotating to adjust the position of the connecting groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This fast-feeding kneader, during the process of separating the conveying pipe from the kneading equipment, the pipe body and rack move horizontally away from the kneading equipment. Through the meshing transmission of the rack and gear, the gear drives the turntable to rotate, rotating the connecting groove to the outside of the feed pipe. At this time, other positions of the turntable block the feed pipe. The turntable prevents external dust, moisture or foreign objects from entering the interior of the kneader body through the feed pipe, thereby preventing the residual material inside the kneader from deteriorating or clumping, affecting the subsequent use of the kneader. During the process of installing the conveying pipe on the kneading equipment, the rack drives the gear and turntable to rotate in the opposite direction, causing the connecting groove to rotate to the position connecting with the internal channel of the feed pipe. Then, the worker can transport the material into the interior of the kneader body through the screw conveyor, thereby realizing the fast feeding of the kneader. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] Please see Figure 1 As shown, one of the objectives of this embodiment is to provide a kneader that can quickly feed materials, including a kneader device 1. The kneader device 1 includes a kneader body 11, a feed pipe 12 fixed to the upper side wall of the kneader body 11, a conveying pipe 2 arranged above the feed pipe 12, and a screw conveyor connected to the outside of the conveying pipe 2. The screw conveyor can transport materials into the interior of the conveying pipe 2. The conveying pipe 2 includes a pipe body 21, and a turntable 3 is rotatably arranged on one side of the feed pipe 12. (Refer to...) Figure 7 A connecting groove 32 is provided on the turntable 3 near its edge, and a side groove 121 is provided on the side wall of the feed pipe 12 at a position corresponding to the turntable 3. One side of the turntable 3 is rotatably disposed inside the side groove 121. A linkage mechanism is provided on the upper side of the turntable 3, and a locking mechanism 4 is provided on the feed pipe 12. When the pipe body 21 moves directly above the feed pipe 12 and connects with the feed pipe 12, the locking mechanism 4 positions and locks the pipe body 21. The pipe body 21 is fixed by the locking mechanism 4, so that the pipe body 21 is fixed. The body 21 is fixed at the upper end of the feed pipe 12. During the process of fixing the body 21, the body 21 drives the turntable 3 to rotate through the linkage mechanism, so that the connecting groove 32 rotates to the position of connecting with the internal channel of the feed pipe 12. At this time, the feed pipe 12 is in the open state. After the screw conveyor transports the material into the interior of the body 21, the material falls into the interior of the kneader body 11 through the feed pipe 12 under the action of gravity. The material is stirred and mixed by the kneader body 11, thereby realizing the rapid feeding of the kneader.
[0029] The structure of locking mechanism 4 is described in detail below, with reference to... Figure 2 , Figure 3 and Figure 5The locking mechanism 4 includes a tray 41 fixedly sleeved on the outer circumference of the feed pipe 12. The bottom side of the tray 41 and the upper side wall of the feed pipe 12 are at the same height. The tray 41 has symmetrical movable slots 411 on both sides. Two T-shaped sliders 22 are symmetrically fixed on the side wall of the pipe body 21. When the pipe body 21 is connected to the feed pipe 12, the lower end of the pipe body 21 is located inside the tray 41. The two T-shaped sliders 22 are slidably disposed inside the two movable slots 411 respectively. The T-shaped slider 22 consists of a horizontal block fixed on the side wall of the pipe body 21 and a vertical block fixed at the other end of the horizontal section. The horizontal block of the T-shaped slider 22 is slidably disposed inside the corresponding movable slot 411. The vertical block of the T-shaped slider 22 contacts the outer side wall of the tray 41. The vertical block and the outer side wall of the tray 41 cooperate to prevent the pipe body 21 from rotating around its own axis and restrict one degree of freedom of the pipe body 21 in the horizontal direction. The horizontal block and the corresponding movable slot 411 cooperate to restrict the degree of freedom of the pipe body 21 in the vertical direction.
[0030] Reference Figure 6 The locking mechanism 4 also includes an end plate 43 disposed below the tray 41. The end plate 43 is disposed on one side of the feed pipe 12. A wedge 42 is fixedly disposed on the upper side wall of the end plate 43. The upper end of the wedge 42 slides through the tray 41 and extends outward. The side of the upper end face of the wedge 42 away from the feed pipe 12 is set as an inclined surface. The locking mechanism 4 also includes two guide rods 44 vertically disposed on both sides of the wedge 42. The upper end of the guide rods 44 is fixedly disposed on the lower side wall of the tray 41. The lower end of the guide rods 44 slides through the end plate 43 and extends outward. A spring 45 is fixed between the end plate 43 and the tray 41 and sleeved on the guide rod 44. 45 drives the end plate 43 closer to the tray 41, so that the upper end of the wedge 42 is stable inside the tray 41 when it is not under downward pressure. At the same time, the side of the tray 41 near the feed pipe 12 is set as a semi-circle coaxial with the feed pipe 12. When the pipe body 21 is connected to the feed pipe 12, the semi-circular inner wall of the tray 41 and the wedge 42 are symmetrically distributed about the axis of the pipe body 21. The semi-circular inner wall of the tray 41 is in contact with the pipe body 21, and the wedge 42 is also in contact with the circumferential outer wall of the pipe body 21. The tray 41 and the wedge 42 cooperate to restrict the other degree of freedom of the pipe body 21 in the horizontal direction, thereby fixing the pipe body 21 in the position connected to the feed pipe 12.
[0031] The following details the structure of the linkage mechanism, referring to... Figure 3 and Figure 4The linkage mechanism includes a gear 31 coaxially fixed to the upper side wall of the turntable 3 via a spline. The diameter of the connecting groove 32 is smaller than the radius of the turntable 3, and the axis of the turntable 3 is located on one side of the feed pipe 12. A rack 23 is fixedly mounted on the side wall of the pipe body 21 via a bracket. When the lower end of the pipe body 21 is inside the tray 41, two T-shaped sliders 22 are respectively located inside the corresponding movable grooves 411. The T-shaped sliders 22 and the corresponding movable grooves 411 cooperate to prevent the pipe body 21 from rotating around its own axis and moving vertically. Therefore, the rack 23 will be... The rack 23 is positioned corresponding to the gear 31 to ensure that the rack 23 and the gear 31 mesh. When the worker pushes the conveying pipe 2 and the external screw conveyor toward the feed pipe 12, the T-shaped slider 22 slides inside the corresponding movable groove 411. Through the meshing transmission of the rack 23 and the gear 31, the gear 31 drives the turntable 3 to rotate. When the pipe body 21 moves to the position where it is aligned and connected with the feed pipe 12, the connecting groove 32 rotates to the position where it is connected to the internal channel of the feed pipe 12, thereby ensuring that the feed pipe 12 is in the open state.
[0032] When using this device, the worker pushes the conveying pipe 2 and the screw conveyor toward the feed pipe 12, so that the lower end of the pipe body 21 contacts the bottom side of the tray 41. The two T-shaped sliders 22 are respectively slidably set inside the corresponding movable grooves 411. When the lower end of the pipe body 21 contacts the inclined surface of the wedge 42, the pipe body 21 squeezes the wedge 42, causing the wedge 42 to move downward. The wedge 42 drives the end plate 43 to move downward synchronously along the axis of the guide rod 44, so that the spring 45 is stretched. When the pipe body 21 moves past the wedge 42 to the position connected with the feed pipe 12, the rebounding spring 45 drives the end plate 43 and the wedge 42 to move upward and reset, so that the tray 41 and the wedge 42 cooperate to restrict the other degree of freedom of the pipe body 21 in the horizontal direction, thereby fixing the pipe body 21 in the position connected with the feed pipe 12. After the pipe body 21 is fixed on the feed pipe 12, the connecting groove 32 is connected to the feed pipe 12, and the worker can quickly feed materials into the interior of the kneader body 11 through the screw conveyor.
[0033] When the kneading machine 1 is idle, the worker manually pulls the end plate 43 downwards, causing the end plate 43 to move the wedge 42 downwards until the upper end of the wedge 42 moves below the bottom side of the tray 41. This releases the horizontal restriction of the wedge 42 on the pipe body 21. Then, the worker pulls the screw conveyor and the conveying pipe 2 horizontally away from the kneading machine 1, thus separating the conveying pipe 2 from the kneading machine 1, allowing the worker to store the conveying pipe 2 and the kneading machine 1 separately. To improve the utilization of storage space, during the process of separating the conveying pipe 2 from the kneading machine 1, the gear 31 drives the turntable 3 to rotate in the opposite direction through the meshing transmission of the rack 23 and the gear 31, rotating the connecting groove 32 to the outside of the feed pipe 12. At this time, one side of the turntable 3 blocks the feed pipe 12, preventing external dust, moisture or foreign objects from entering the interior of the kneading machine body 11 through the feed pipe 12, thereby preventing the material inside the kneading machine from deteriorating or clumping and affecting the subsequent use of the kneading machine.
