Description

Technical Field

[0001] The invention relates to the technical field of kneading machines, in particular to a kneading machine which is convenient for mixing and heating. Background Art

[0002] Kneader is a special mixing and stirring equipment, mainly used for kneading, mixing, vulcanizing, and polymerizing high-viscosity, elastic-plastic materials. Some kneaders often use two Σ blades to knead the raw materials. These blades are often arranged in a side-by-side tangential differential speed type, that is, one stirring paddle has a fast speed and the other has a slow speed, so as to generate shear force, so that the materials can be quickly sheared and mixed evenly. The kneaded raw materials can be transported out from the auger at the bottom of the kneading box;

[0003] At present, kneading machines basically use a shaft to rotate paddles to knead the raw materials when mixing raw materials. The raw materials within the rotation range of the paddles can be kneaded in time as the paddles rotate. However, the raw materials in the internal space of the kneading box above the rotation range of the paddles are not easy to fully contact and engage with the paddles, and most kneading boxes have a simple structure and only have the function of holding raw materials, and are not easy to assist the paddles to fully knead and mix the raw materials. Summary of the invention

[0004] The object of the present invention is to provide a kneading machine which is convenient for mixing and heating, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A kneading machine for convenient mixing and heating comprises a kneading box, the kneading box comprises two baffles, two side plates are fixed between the two baffles, a rectangular frame is slidably connected inside the side plates, an extrusion plate 1 is fixed at one end of the rectangular frame, two shafts are rotatably connected between the two baffles, a plurality of symmetrically arranged paddles are fixed on the outer side of the shaft, a gear 1 is fixed at one end of the shaft, two gears 2 which are respectively meshed and driven with the corresponding position gear 1 are rotatably connected to the outer side of the side plates, a transmission mechanism and a connecting rod mechanism for driving the rectangular frame to move are arranged between the gear 2 and the corresponding position rectangular frame, the transmission mechanism comprises a transmission rod rotatably connected to the gear 2, one end of the transmission rod is rotatably connected to an L-shaped shaft, the connecting rod mechanism comprises a positioning shaft, a connecting rod 1 which is movably plugged with the L-shaped shaft is sleeved and fixed on the outer side of the positioning shaft, a connecting rod 2 for driving the rectangular frame to move is sleeved and fixed on the outer side of the positioning shaft, an L-shaped frame is fixed on the open end of the kneading box, two electric push rods are fixed at the bottom of the L-shaped frame, and an extrusion plate 2 is fixed at the output end of the electric push rod.

[0007] Furthermore, two U-shaped frames are fixed to both the top and bottom of the rectangular frame. One end of the second connecting rod is fixed with a movable rod, and both ends of the movable rod are movably inserted into the U-shaped frames at corresponding positions.

[0008] Furthermore, support legs are fixed at the four corner positions of the bottom surface of the kneading box, and the bottom end of the positioning shaft is rotatably connected to the support legs at corresponding positions.

[0009] Furthermore, one end of the transmission rod is rotatably connected to a connecting shaft fixedly connected to the second gear, and the connecting shaft is arranged at a position deviating from the center of the second gear.

[0010] Furthermore, a limiting member is sleeved on the top of the L-shaped shaft. The limiting member includes two limiting rings. The limiting ring at the top position is fixedly connected to the L-shaped shaft, and the limiting ring at the bottom position is slidably abutted against the top surface of the first connecting rod. A return spring is fixed between the two limiting rings.

[0011] Furthermore, a stop block is fixed to the bottom end of the L-shaped shaft, and a movable hole for the L-shaped shaft to pass through is formed through the top surface of the first connecting rod.

[0012] Furthermore, a auger for conveying materials is rotatably connected to the middle position of the bottom of the kneading box. One end of the auger is fixed with a belt pulley, and a support plate fixedly connected to the bottom of the kneading box is arranged below the auger.

[0013] Furthermore, a machine box is arranged at one end of the kneading box. Two reduction motors are fixed inside the machine box. The output ends of the reduction motors are respectively fixedly connected to the shaft rods at corresponding positions, and two support columns are fixed to the bottom surface of the machine box.

[0014] Furthermore, heating wires are embedded and fixed inside the second extrusion plate, and machine casings are fixed to both ends of the kneading box.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By extending the output end of the electric push rod, the second extrusion plate moves towards the inside of the kneading box, which is convenient for squeezing the raw materials in the space above the rotation range of the paddle to the paddle position, so that the paddle can timely knead the raw materials at the top position inside the kneading box. By adjusting the paddle on the shaft rod to the horizontal placement position (refer to the instruction manual Fig. 9 ), at this time, the second extrusion plate can move down to the maximum extent above the paddle. During the downward movement of the second extrusion plate, it is convenient to fully squeeze the kneaded raw materials to the auger position, and the raw materials are quickly conveyed out as the auger rotates. Moreover, heating wires are embedded and fixed inside the second extrusion plate, and the heating wires are energized to generate heat, so that the temperature of the second extrusion plate rises. When the second extrusion plate covers the open end of the kneading box, it is convenient to heat the raw materials inside the kneading box.

[0017] 2. By using two reduction motors to rotate the two shafts in different directions and speeds, the paddles on the two shafts can rotate to the middle position inside the kneading box at different speeds to engage the raw materials. The rotation speeds of the paddles on the two shafts are different to generate shear force, so that the materials can be quickly sheared and mixed evenly.

[0018] 3. A rectangular frame is slidably connected on both sides of the kneading box, and an extrusion plate 1 is fixed at one end of the rectangular frame. When the shaft rotates with the paddles to knead the raw materials, the gear 1 at the end of the shaft rotates, and the gear 1 rotates with the gear 2 on its outer side. The rotation of the gear 2 drives the L-shaped shaft on the transmission rod to push the connecting rod 1, and the connecting rod 1 rotates with the positioning shaft so that the connecting rod 2 on the positioning shaft drives the movable shaft to push the rectangular frame inside the kneading box. The rectangular frame moves the extrusion plate 1 toward the inside of the kneading box, which is convenient for tamping the raw materials on both sides of the meshing box in the center, so that the raw materials and the paddles are fully kneaded and mixed. The volume inside the kneading box is regulated by moving the position of the extrusion plate 1, so that the raw materials can actively move toward the direction of the paddles for mixing.

[0019] 4. By setting the number of teeth of gear one to twice the number of teeth of gear two, that is, every time gear one rotates 90 degrees, gear two will rotate 180 degrees, so that when the shaft rod leads the paddle to rotate away from the side plate position, the transmission mechanism cooperates with the connecting rod mechanism to lead the extrusion plate one to move to the spatial position after the paddle rotates away; when the shaft rod leads the paddle to rotate toward the side plate, the transmission mechanism cooperates with the connecting rod mechanism to lead the extrusion plate one away from the kneading box, so that the paddle kneading raw materials and the extrusion plate one extrusion raw materials do not interfere with each other, and the raw materials on both sides of the meshing box can be pushed synchronously during the process of the paddle kneading the raw materials, which is beneficial to improve the efficiency of the kneading machine in kneading and mixing raw materials.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Example 1, please refer to Figure 1-9In an embodiment of the present invention, a kneading machine for mixing and heating includes a kneading box 100, which includes two baffles 110, two side plates 120 are fixed between the two baffles 110, a rectangular frame 200 is slidably connected inside the side plates 120, an extrusion plate 1 210 is fixed at one end of the rectangular frame 200, two shafts 300 are rotatably connected between the two baffles 110, a plurality of symmetrically arranged paddles 310 are fixed on the outside of the shafts 300, a gear 1 320 is fixed on one end of the shafts 300, two gears 2 111 are rotatably connected to the outside of the side plates 120, and the gears 1 320 are meshed and driven with the corresponding positions of the gears 1 320, and the gears 111 and the rectangular frames 200 are connected to the corresponding positions of the gears 1 111 and the corresponding positions of the gears ... rectangular frames 200. A transmission mechanism 500 and a connecting rod mechanism 600 are provided for driving the rectangular frame 200 to move. The transmission mechanism 500 includes a transmission rod 510 rotatably connected to the gear 2 111, and one end of the transmission rod 510 is rotatably connected to an L-shaped shaft 520. The connecting rod mechanism 600 includes a positioning shaft 610, and a connecting rod 1 620 movably plugged with the L-shaped shaft 520 is fixed to the outer side of the positioning shaft 610. A connecting rod 2 630 for driving the rectangular frame 200 to move is fixed to the outer side of the positioning shaft 610. An L-shaped frame 700 is fixed to the open end of the kneading box 100, and two electric push rods 710 are fixed to the bottom of the L-shaped frame 700, and an extrusion plate 2 711 is fixed to the output end of the electric push rod 710.

[0032] Specifically, the kneading box 100 includes two baffles 110, two side plates 120 are fixed between the two baffles 110, a rectangular frame 200 is slidably connected inside the side plates 120, an extrusion plate 210 is fixed at one end of the rectangular frame 200, two shafts 300 are rotatably connected between the two baffles 110, a plurality of symmetrically arranged paddles 310 are fixed on the outer side of the shaft 300, a gear 320 is fixed at one end of the shaft 300, two gears 111 are rotatably connected to the outer side of the side plates 120, and the gears 111 and the corresponding positions of the gears 111 are respectively meshed and driven, and a gear 111 is provided between the gear 111 and the corresponding position of the rectangular frame 200 for driving the rectangular frame 200. The transmission mechanism 500 and the connecting rod mechanism 600 for moving the rectangular frame 200, the transmission mechanism 500 includes a transmission rod 510 rotatably connected to the gear 2 111, one end of the transmission rod 510 is rotatably connected to an L-shaped shaft 520, the connecting rod mechanism 600 includes a positioning shaft 610, the outer side of the positioning shaft 610 is sleeved and fixed with a connecting rod 1 620 movably plugged with the L-shaped shaft 520, the outer side of the positioning shaft 610 is sleeved and fixed with a connecting rod 2 630 for driving the rectangular frame 200 to move, the open end of the kneading box 100 is fixed with an L-shaped frame 700, the bottom of the L-shaped frame 700 is fixed with two electric push rods 710, and the output end of the electric push rod 710 is fixed with an extrusion plate 2 711.

[0033] like Figure 4As shown, in this embodiment, two U-shaped frames 220 are fixed to both the top and bottom of the rectangular frame 200. One end of the second connecting rod 630 is fixed with a movable rod 640, and both ends of the movable rod 640 are movably inserted into the U-shaped frames 220 at corresponding positions.

[0034] In this embodiment, the length of the space for the movable rod 640 to move between the U-shaped frame 220 and the rectangular frame 200 is greater than the diameter of the movable rod 640. Thus, during the process of the positioning shaft 610 driving the movable rod 640 to swing back and forth through the second connecting rod 630, the movable rod 640 at the end of the second connecting rod 630 can drive the rectangular frame 200 to linearly reciprocate through the U-shaped frame 220, prompting the rectangular frame 200 to drive the first pressing plate 210 to reciprocally squeeze and knead the raw materials on both sides inside the kneading box 100 closer to the paddle 310 for mixing.

[0035] As Figure 2 shown, in this embodiment, support legs 150 are fixed at the four corner positions of the bottom surface of the kneading box 100. The bottom end of the positioning shaft 610 is rotatably connected to the corresponding support legs 150. The support legs 150 enable the kneading machine to be supported and fixed on the ground, and at the same time, the top surface of the support legs 150 can provide a place for the positioning shaft 610 to rotate, playing a role in supporting the positioning shaft 610.

[0036] As Figure 4 and Figure 5 shown, in this embodiment, one end of the transmission rod 510 is rotatably connected to a connecting shaft 511 fixedly connected to the second gear 111. The connecting shaft 511 is arranged at a position deviating from the center of the second gear 111. By fixing the connecting shaft 511 at a position deviating from the center of the second gear 111, during the process of the first gear 320 driving the second gear 111 to rotate, the second gear 111 will drive the transmission rod 510 to reciprocally push the L-shaped shaft 520 to move through the connecting shaft 511, so that the L-shaped shaft 520 can reciprocally push and pull the first connecting rod 620 to move.

[0037] As Figure 4-6 shown, in this embodiment, a limiting member 530 is sleeved on the top of the L-shaped shaft 520. The limiting member 530 includes two limiting rings 531. The limiting ring 531 at the top position is fixedly connected to the L-shaped shaft 520, and the limiting ring 531 at the bottom position is slidably abutted against the top surface of the first connecting rod 620. A return spring 532 is fixed between the two limiting rings 531. A stop block 521 is fixed to the bottom end of the L-shaped shaft 520, and a movable hole 621 for the L-shaped shaft 520 to pass through is formed through the top surface of the first connecting rod 620.

[0038] In the present embodiment, during the process of the gear 2 111 driving the transmission rod 510 to push and pull the L-shaped shaft 520 back and forth, the end of the transmission rod 510 close to the connecting shaft 511 will change in height as the gear 2 111 rotates. When the height of the end of the transmission rod 510 close to the connecting shaft 511 increases, the transmission rod 510 will move downward with the L-shaped shaft 520. At this time, the top position limit ring 531 squeezes the reset spring 532. After that, when the end of the transmission rod 510 close to the connecting shaft 511 rotates to the initial position height, the transmission rod 510 is restored to a horizontal arrangement again under the elastic force of the reset spring 532. When the height of one end of the transmission rod 510 close to the connecting shaft 511 is reduced, the transmission rod 510 will move upward with the L-shaped shaft 520. At this time, the stopper 521 on the L-shaped shaft 520 can prevent the L-shaped shaft 520 from escaping from the movable hole 621 on the connecting rod 1 620. The opening length of the movable hole 621 is greater than the diameter of the L-shaped shaft 520, thereby meeting the space requirement for the L-shaped shaft 520 to move on the connecting rod 1 620. In the process of the L-shaped shaft 520 moving with the connecting rod 1 620, the L-shaped shaft 520 will slide horizontally in the movable hole 621 and move up and down in the movable hole 621.

[0039] like Figure 3 and Fig. 9 As shown, in this embodiment, an auger 130 for conveying materials is rotatably connected to the middle position of the bottom of the kneading box 100, a pulley is fixed to one end of the auger 130, and a support plate 140 fixedly connected to the bottom of the kneading box 100 is arranged below the auger 130.

[0040] In this embodiment, when the kneaded raw materials need to be squeezed and transported out, an external driving motor can be made to rotate the pulley through a belt, and the pulley drives the auger 130 to rotate to transport the raw materials inside the kneading box 100 out. This part is a commonly used method for discharging materials from the bottom of the kneading machine, and the specific discharging details and principles are not elaborated here.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, a chassis 400 is arranged at one end of the kneading box 100, two reduction motors 410 are fixed inside the chassis 400, the output ends of the reduction motors 410 are fixedly connected to the corresponding shafts 300, and two support columns 420 are fixed to the bottom surface of the chassis 400.

[0042] In this embodiment, two reduction motors 410 can drive the shaft rods 300 at corresponding positions to rotate at different speeds, so that the blades 310 on the two shaft rods 300 can knead the raw materials at different speeds. The blades 310 on the two shaft rods 300 can rotate towards the middle position inside the kneading box 100 at different speeds to knead the raw materials, so as to generate a shearing force, enabling the物料 to be quickly sheared and mixed evenly. Also, the two reduction motors 410 can rotate in opposite or the same direction, causing the two shaft rods 300 to drive the blades 310 at different positions to knead the raw materials in opposite or the same direction. Moreover, the two reduction motors 410 can drive the shaft rods 300 to rotate at the same speed or different speeds, realizing the control of the magnitude of the shearing force when the two shaft rods 300 drive the blades 310 to rotate, and achieving the regulation of the magnitude of the shearing force according to the kneading state of the raw materials under actual conditions.

[0043] During specific implementation, referring to the figure in the specification Figure 2 , the output end of the electric push rod 710 drives the second pressing plate 711 to move upward, and the raw materials to be kneaded can be put into the interior of the kneading box 100 from the space between the second pressing plate 711 and the open mouth of the kneading box 100. The two reduction motors 410 inside the machine case 400 drive the two shaft rods 300 with the blades 310 to rotate synchronously in opposite directions and at different speeds. The specific rotation direction refers to the arrow indication direction outside the first gear 320 in the specification Figure 3 . During the process of the shaft rod 300 driving the blade 310 to rotate and stir the raw materials, the first gear 320 outside the shaft rod 300 will drive the second gear 111 to rotate. The second gear 111 drives the transmission rod 510 to push and pull the L-shaped shaft 520 back and forth through the eccentrically arranged second gear 111. The L-shaped shaft 520 will push and pull the first connecting rod 620 back and forth to make the positioning shaft 610 rotate reciprocally in positive and negative directions, so that the positioning shaft 610 drives the second connecting rod 630 to push and pull the movable rod 640 back and forth. The movable rod 640 drives the rectangular frame 200 to slide reciprocally on both sides of the kneading box 100 through the C-shaped frame 220, so that the first pressing plate 210 can cyclically push the raw materials on both sides inside the kneading box 100 towards the blade 310, prompting the blade 310 to fully knead and mix the raw materials. Since the rotation speeds of the two shaft rods 300 can be individually controlled by the reduction motors 410 at different positions, the rotation speeds of the two shaft rods 300 can be different, and further, the first pressing plates 210 driven by the first gear 320 through the transmission mechanism 500 and the link mechanism 600 can also move out of sync. Refer to the specification Figure 3 For the case where a single first pressing plate 210 presses the raw materials, refer to the specification Figure 8 For the case where two first pressing plates 210 press the raw materials simultaneously.

[0044] Embodiment 2, based on embodiment 1, is to enable the raw materials in the space above the blade 310 to actively move toward the blade 310 for kneading, and to compact the raw materials and move them to the auger 130 for delivery during the later discharging.

[0045] like Figure 1 As shown, in this embodiment, an L-shaped frame 700 is fixed to the open end of the kneading box 100, two electric push rods 710 are fixed to the bottom of the L-shaped frame 700, and an extrusion plate 711 is fixed to the output end of the electric push rod 710. A heating wire is embedded and fixed inside the extrusion plate 711, and a housing 160 is fixed to both ends of the kneading box 100.

[0046] Specifically, the working principle of heating the heating wire by connecting it with a wire to generate electricity and heat is the prior art, and the specific content will not be repeated here. In the process of the extrusion plate 2 711 blocking the open end of the kneading box 100, the extrusion plate 2 711 can be heated, and the output end of the electric push rod 710 is used to move the extrusion plate 2 711 down to the open end of the kneading box 100, thereby increasing the temperature inside the kneading box 100 to meet the need for heating some raw materials during kneading and mixing. The casing 160 is shielded on the outside of the gear 1 320 and the gear 2 111, and mainly plays a protective role.

[0047] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0048] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
