Description

Technical Field

[0001] The invention relates to the technical field of automatic kneading machines, in particular to an automatic kneading machine. Background Art

[0002] Kneading machine is an ideal equipment for kneading, mixing, vulcanizing and polymerizing high viscosity and elastic plastic materials. Kneading machine can be used to produce silicone rubber, sealant, hot melt adhesive, food glue base, pharmaceutical preparations, etc. Kneading machine is a special mixing and stirring equipment. The most commonly used is to use two Σ blades, arranged in a side-by-side tangent differential speed type, that is, one stirring blade has a fast speed and the other has a slow speed, so as to generate shear force. Different paddle speeds enable the mixed materials to be sheared quickly, so that the materials can be mixed evenly. Sometimes powdered materials are added during meshing and stirring. These powdered materials will be partially contaminated on the inner wall of the kneading machine during kneading and stirring. The powder on the inner wall outside the stirring range of the blades is difficult to be re-involved in kneading in time, resulting in the flipped colloid material in the second half of kneading randomly re-involving the powder on the side wall, which affects the kneading uniformity and prolongs the kneading processing time.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6In an embodiment of the present invention, an automated kneading machine includes a horizontal kneading tank 100, two mirror-image kneading paddles 130 are rotatably connected between the two ends of the horizontal kneading tank 100, a driving motor 110 is provided at one end of the horizontal kneading tank 100, a transmission box 120 is transmission-connected between the paddle shafts at one end of the two kneading paddles 130, end surface pushing mechanisms 300 are provided above both ends of the kneading paddles 130, side surface pushing mechanisms 200 are provided on both sides of the top of the horizontal kneading tank 100, and the end surface pushing mechanisms 300 include a vertical plate 310, a seat plate 311 is fixedly connected to the bottom end of the vertical plate 310, and the seat plate 311 is connected to the top of the horizontal kneading tank 100. The bottom and top sides of one side wall of the vertical plate 310 are both rotatably connected with a driving belt 330, and the two ends of the two driving belts 330 corresponding to the one side wall of the vertical plate 310 are both rotatably connected with a transmission rod 331, and one end of the transmission rod 331 is fixedly sleeved with a driving wheel 332, and the driving wheel 332 is transmission-connected to the adjacent driving belt 330; the outer side wall of the driving belt 330 is fixedly connected with a round rod, and a push rod assembly 340 is rotatably connected between the two round rods, and the two transmission rods 331 located at one end of the vertical plate 310 are both transmission-connected to the kneading paddle 130 on the corresponding side, and the driving belt 330 transmits one full circle when the kneading paddle 130 rotates one circle.

[0030] Specifically, after the powder is added into the horizontal kneading tank 100, the driving motor 110 drives the two kneading paddles 130 through the transmission box 120, and the two kneading paddles 130 rotate relative to each other to stir and knead the materials in the horizontal kneading tank 100. When the kneading paddles 130 rotate, the transmission rod 1 331 is driven to rotate, thereby driving the two driving belts 330 to drive, so as to drive the push rod assembly 340 to move in a circular shape. When the kneading paddles 130 rotate one circle, the push rod assembly 340 is driven to move one circle. When moving, the push rod assembly 340 pushes the powder on the end surface of the horizontal kneading tank 100 sideways, thereby pushing the powder on the end surface back to the stirring range of the kneading paddles 130. At the same time, the side pushing mechanism 200 pushes the powder on the inner walls on both sides of the horizontal kneading tank 100 downward, so that the powder on the inner walls on both sides returns to the stirring range of the kneading paddles 130, thereby improving the uniformity of kneading and improving the kneading efficiency. Example

[0031] like Figures 2 to 6As shown, in this embodiment, a transmission rod 2 333 is rotatably connected to the middle position of the two driving belts 330 corresponding to one side wall of the vertical plate 310, and one end of the transmission rod 2 333 is rotatably connected to a driving wheel 2 334, and the driving wheel 2 334 is transmission-connected to the adjacent driving belt 330, and the height position of the driving wheel 2 334 is higher than the position of the two driving wheels 1 332 located on the same driving belt 330. The transmission module 320 includes an axle 1 321 and a pulley 4 323, and the axle 1 The rod 1 321 is rotatably connected to the top of the seat plate 311, one end of the shaft rod 1 321 is fixedly connected to the other end of a transmission rod 1 331, and the other ends of the two transmission rods 1 331 at one end of the vertical plate 310 are fixedly sleeved with a pulley 5 325, and a transmission belt 3 326 is transmission-connected between the two pulleys 5 325, one end of the shaft rod 1 321 is fixedly sleeved with a pulley 3 322, and the pulley 4 323 is fixedly sleeved with the paddle shaft of the kneading paddle 130 adjacent to the corresponding side. The side push mechanism 200 includes a push plate 220, both ends of the outer wall of the push plate 220 are fixedly connected with a fixed arm 230, the top of the fixed arm 230 is provided with a long groove 231, the top of the horizontal kneading tank 100 is fixedly connected with a rotating seat 210 corresponding to the position of the fixed arm 230, the top of the rotating seat 210 is rotatably connected with a crank arm 240, one end of the crank arm 240 is provided with a crankshaft portion 241, the crankshaft portion 241 is slidably connected to the inner wall of the adjacent long groove 231, and the crank arm 240 is provided with a crankshaft portion 241. The other end is transmission-connected with the adjacent end of the kneading paddle 130 on the corresponding side. The other end of the crank arm 240 is fixedly connected with a pulley 242. A pulley 243 is arranged on the outer side of the pulley 242. The pulley 243 is fixedly sleeved with the paddle shaft of the adjacent end of the kneading paddle 130 on the corresponding side. A transmission belt 244 is transmission-connected between the pulley 242 and the pulley 243. The outer diameter of the pulley 243 is twice the outer diameter of the pulley 1 242. The kneading paddle 130 is an existing Σ blade structure.

[0032] In this embodiment, when the kneading paddle 130 rotates, it drives the pulley 4 323 to rotate. The pulley 4 323 drives the shaft rod 1 321 to rotate through the transmission belt 2 324 and the pulley 3 322. The shaft rod 1 321 drives the two transmission rods 1 331 on the adjacent side to rotate, thereby driving the two driving belts 330 to rotate. The driving belt 330 drives the push rod assembly 340 to move in a circle in a vertical state through the round rod. When the round rod moves between the two driving wheels 1 332, the bottom end of the push rod assembly 340 reaches the stirring position of the kneading paddle 130. In the annular range, taking the left kneading paddle 130 and the end face pushing mechanism 300 at one end of the left side as an example, when the left kneading paddle 130 rotates counterclockwise, the push rod assembly 340 moves counterclockwise along the driving belt 330, and the push rod assembly 340 is staggered with the paddle portion at one end of the kneading paddle 130. Since the push rod assembly 340 also moves one circle along the driving belt 330 when the kneading paddle 130 rotates one circle, the push rod assembly 340 is prevented from interfering with the paddle portion at one end of the kneading paddle 130. When the push rod assembly 340 moves from left to right, When the push rod assembly 340 moves from right to left, the bottom end of the push rod assembly 340 moves upward and thus separates from the rotation range of the blade portion at one end of the kneading paddle 130. When the kneading paddle 130 rotates, the crank arm 243, the transmission belt 144, and the pulley 142 are driven to rotate. 40 rotates, the crank arm 240 drives the fixed arm 230 to move up and down through the crankshaft portion 241, thereby driving the push plate 220 to move up and down, and the kneading paddle 130 rotates one circle, and the push plate 220 reciprocates up and down twice. When the kneading paddle 130 rotates to the point where the paddles at both ends of the kneading paddle 130 are in a vertical state, the push plate 220 moves down to the lowest position. At this time, the blade edge of the kneading paddle 130 on the left side is located away from the vertical inner wall on the left side of the horizontal kneading tank 100, thereby preventing the push plate 220 from contacting the material covered or rolled up by the blade edge. Example

[0033] like Figures 3 to 9As shown, in the present embodiment, the push rod assembly 340 includes a fixed rod 341, which is rotatably connected with the two round rods, a contact rod 346 is provided at the bottom end of the fixed rod 341, and a shaft rod 347 is fixedly connected to the top of the contact rod 346, and the shaft rod 347 is rotatably connected to the bottom end of the fixed rod 341, and a gear 1 348 is fixedly sleeved at the middle position of the shaft rod 347, and a groove is provided at the bottom end of the fixed rod 341 corresponding to the upper part of the gear 1 348, and a gear 2 349 is rotatably connected between the inner walls on both sides of the bottom end of the fixed rod 341, and the gear 2 349 meshes with the gear 1 348, a side wall of the fixed rod 341 is equidistantly fixed with a ring 343, and a plug rod 344 is slidably inserted between multiple rings 343, and a protrusion 345 is fixedly connected to the top of one side wall of the plug rod 344, and a clamping rod 342 is fixedly connected to the top of one side wall of the fixed rod 341. Grooves are provided at both ends of one side wall of 342, and a tooth groove is provided at the bottom end of one side of the insertion rod 344. The bottom end of the insertion rod 344 meshes with the gear 2 349. Lower pressure plates 400 are provided at both ends of the horizontal kneading groove 100. A threaded rod 410 is screwed and connected in the middle position of the lower pressure plate 400. The bottom end of the threaded rod 410 is rotatably connected to the top surface of the horizontal kneading groove 100. Slide rods 312 are slidably inserted at both ends of the top surface of the lower pressure plate 400. The slide rod 312 is fixedly connected to the top surface of the adjacent seat plate 311. The top outer wall of the threaded rod 410 is fixedly connected to a limiting ring 411. The outer diameter of gear 2 349 is larger than the outer diameter of gear 1 348. The outer wall of the vertical plate 310 is fixedly connected to a limiting plate 350. The limiting plate 350 is used to limit the push rod assembly 340. The bottom end of the contact rod 346 is pointed, so that there are two inclined surfaces at the bottom end of the contact rod 346.

[0034] In specific implementation, when the contact rod 346 moves horizontally, the contact rod 346 is inclined at the bottom end to drive the powder material downward when the contact rod 346 moves horizontally. When the kneading process reaches the second half, the material is in a glued state, and almost no new loose powder material will be re-contaminated to the inner side walls of the two ends of the horizontal kneading groove 100. The threaded rod 410 is rotated to move the lower pressure plate 400 downward until the lower pressure plate 400 moves downward to be limited by the limiting ring 411, so that when the fixed rod 341 moves upward, the lower pressure plate 400 squeezes the insertion rod 344, so that the insertion rod 344 is relative to The fixing rod 341 moves downward, and the protrusion 345 is inserted into the groove at the bottom end of the clamping rod 342 from the groove at the top end of the clamping rod 342. The insertion rod 344 moves downward relatively and drives the gear 1 348 to rotate through the gear 2 349, thereby driving the contact rod 346 to deflect upward, so that the contact rod 346 rotates upward half a circle, and the protrusion 345 is engaged with the groove at the bottom end of the clamping rod 342 to limit the contact rod 346, so that the contact rod 346 can be folded upward and retracted, thereby avoiding ineffective friction between the contact rod 346 and the inner side wall of the end of the horizontal kneading groove 100.

[0035] 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.
