Description

Technical Field

[0001] This invention relates to tea oil filling technology, specifically a tea oil filling and conveying line. Background Technology

[0002] As is widely known, tea oil is the liquid extracted from the seeds of the tea tree. It is one of the oldest edible oils. When storing high-grade edible oils, glass oil bottles are often used for filling. The glass material will not react chemically with the edible oil, and it is also convenient to observe the color and texture of the edible oil.

[0003] For example, the invention patent with publication number CN109007982B, publication date March 15, 2022, entitled "Automatic E-liquid Filling Equipment for E-liquid Bottles," includes: a conveying mechanism, including a conveyor belt for conveying e-liquid bottles; and a filling mechanism, including a measuring component and several filling heads. The measuring component is used to detect whether the e-liquid bottle has moved to the filling position. The filling heads are arranged sequentially above the filling position along the direction in which the e-liquid bottle is conveyed by the conveyor belt, so that when the measuring component detects that the e-liquid bottle has moved to the filling position, the filling head can inject e-liquid into the e-liquid bottle. The above-mentioned automatic e-liquid filling equipment can fill multiple e-liquid bottles simultaneously, has high production efficiency, and can achieve automatic alignment between the filling head and the e-liquid bottle, preventing e-liquid from spilling onto the outside of the e-liquid bottle.

[0004] The shortcoming of the existing technology is that when filling the glass oil bottle with oil, in order to avoid oil contamination, the outer wall of the filling head of the filling machine only stays at the mouth of the glass oil bottle before directly filling the glass oil bottle with oil. At this time, there is a certain distance between the oil and the bottom of the bottle, which causes air bubbles to be generated in the bottle when the oil falls in because of the high viscosity of tea oil. The residual air bubbles will reduce the shelf life of the tea oil. Summary of the Invention

[0005] The purpose of this invention is to provide a tea oil filling and processing conveyor line to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tea oil bottling and processing conveyor line, comprising a filling machine and a food-grade chain conveyor belt mounted on the filling machine for conveying glass oil bottles, wherein the filling machine is respectively equipped with: The limiting mechanism includes a top limiting frame arranged along the conveying direction and a bottom limiting frame arranged perpendicular to the conveying direction, both of which limit the glass oil bottle. The bottom limiting frame includes two horizontal intercepting plates fitted with rubber strips. The oil filling mechanism includes a vertical drive frame and a filling head movably mounted on the vertical drive frame. The filling head is connected to the oil supply pipe on the filling machine. The end of the filling head is provided with an oil outlet half-port. The glass oil bottle is provided with an oil limiting recess corresponding to the oil outlet half-port. The two filling heads move closer to each other along the vertical drive frame and fit against the inner wall of the glass oil bottle as oil is being poured.

[0007] As a further description of the above technical solution: the vertical drive frame is provided with a fixed connector, and the two ends of the fixed connector are respectively fixedly connected to an oil supply pipe and a base pipe. The filling head is provided with an oil inlet that is slidably connected to the base pipe, and a first spring is provided between the base pipe and the oil inlet.

[0008] As a further description of the above technical solution: the filling head is provided with a back suction pipe, and the end of the back suction pipe is provided with an oil hole. The back suction pipe sucks up oil when the filling head stops.

[0009] As a further description of the above technical solution: the filling head is provided with a pressure chamber, and the back suction pipe is provided with an elastic plate corresponding to the pressure chamber.

[0010] As a further description of the above technical solution: the vertical drive frame is respectively provided with a fixed connector and a movable connector for fixing the filling head, and the movable connector moves away from the glass oil bottle as the vertical drive frame moves away.

[0011] As a further description of the above technical solution: the movable connector includes a fixed plate disposed on the vertical drive frame, a fixed oil passage head is slidably connected to the fixed plate, and an oil delivery pipe and a base pipe are respectively fixedly connected to both ends of the fixed oil passage head.

[0012] As a further description of the above technical solution: a second spring is provided between the fixed plate and the fixed oil passage head, and a damping element is also included. The damping element includes a first oblique angle and a second oblique angle for limiting the fixed oil passage head.

[0013] As a further description of the above technical solution: a sliding groove is provided on the vertical drive frame, and a locking screw is provided through the sliding groove. The locking screw is threaded to the fixed connector and the movable connector respectively.

[0014] As a further description of the above technical solution: the horizontal interceptor plate has a third oblique angle facing the glass oil bottle, and there are two horizontal interceptor plates. The glass oil bottle between the two horizontal interceptor plates rotates as it is pushed by the rubber strip.

[0015] As a further description of the above technical solution: the top limiting frame includes symmetrically arranged guide plates, and the glass oil bottle is provided with an arc head, the distance between the two guide plates is smaller than the arc head.

[0016] In the above technical solution, the tea oil filling and conveying line provided by the present invention has the following beneficial effects: When filling oil, the two filling heads are close to each other so that the filling heads are in contact with the inner wall of the glass oil bottle to fill oil, so that some oil flows along the inner wall of the bottle and reduces the generation of air bubbles. Then, the horizontal intercepting plate in the half-stroke state continues to move, and the glass oil bottle is driven by the rubber strip to rotate, so that the oil limiting indentation and the oil outlet half-hole are aligned. After the bottom of the bottle is filled with oil, when there is a certain amount of oil at the bottom, the oil is discharged by means of the oil limiting indentation, and most of the oil is guided to flow to the inner wall of the bottle by means of the oil outlet half-hole, reducing oil splashing and air bubbles.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-11 This invention provides a technical solution: a tea oil bottling and processing conveyor line, including a filling machine 1 and a food-grade chain conveyor belt 3 mounted on the filling machine 1 for conveying glass oil bottles 6. The chain plates on the surface of the food-grade chain conveyor belt 3 are stainless steel chain plates. The filling machine 1 is respectively equipped with: The limiting mechanism includes a top limiting frame 4 and a bottom limiting frame 5. The top limiting frame 4 is fixed to the filling machine 1 via a rod-shaped connecting bracket 41 and is used to limit the bottle mouth portion of the glass oil bottle 6 (i.e., limit the upper part of the glass oil bottle 6). A slide rail is provided on the side of the filling machine 1, such as... Figure 1 As shown, the bottom limiting frame 5 is slidably connected to the slide rail and locked by screws. The bottom limiting frame 5 is used to limit the bottom of the glass oil bottle 6, thereby preventing the food-grade chain conveyor belt 3 from driving the glass oil bottle 6. The bottom limiting frame 5 includes two horizontal intercepting plates 51 equipped with rubber strips. The horizontal intercepting plates 51 are driven by cylinders to move closer to or away from the filling machine 1 to block the glass oil bottle 6.

[0022] Oil filling mechanism 2 includes a vertical drive frame 21 that is slidably connected to the filling machine 1 in the vertical direction. The vertical drive frame 21 is driven by a telescopic motor or telescopic cylinder to move in the vertical direction closer to or away from the food-grade chain conveyor belt 3 so as to insert the filling head 22 set on the vertical drive frame 21 into the bottle mouth of the glass oil bottle 6 for oil filling.

[0023] The filling head 22 is connected to the oil supply pipe 20 on the filling machine 1, and the end of the filling head 22 (with) Figure 9 For reference, the lower end (the end) has an oil outlet half-hole 220, and the glass oil bottle 6 has an oil limiting recess 61 corresponding to the oil outlet half-hole 220, such as... Figure 3 As shown, the oil limiting recess 61 is formed by applying pressure to the outside of the glass oil bottle 6 during processing, thus extending into the bottle. The oil limiting recess 61 can limit the amount of oil entering the glass oil bottle 6.

[0024] During oil filling, the food-grade conveyor belt 3 drives the glass oil bottles 6 to move towards the limiting mechanism. When the two glass oil bottles 6 move with the top limiting frame 4 to below the filling head 22, the two filling heads 22 move downwards and approach the glass oil bottles 6 with the vertical drive frame 21. At the same time, the horizontal intercepting plate 51 extends to limit the two glass oil bottles 6. When the horizontal intercepting plate 51 moves to the halfway point and completes the limitation, oil filling begins directly. During oil filling, the two filling heads 22 move closer to each other so that the filling heads 22 fit against the inner wall of the glass oil bottle 6 to fill the oil, so that some of the oil flows along the inner wall of the bottle and reduces the generation of air bubbles. Then, the horizontal intercepting plate 51 in the halfway state continues to move, and the glass oil bottles 6 are rotated by the rubber strip, so that the oil limiting recess 61 and the oil outlet halfway 220 correspond. After the bottom of the bottle is filled with oil, when there is a certain amount of oil at the bottom, the oil is discharged with the help of the oil limiting recess 61, and the oil outlet halfway 220 guides most of the oil to flow to the inner wall of the bottle, reducing oil splashing and air bubbles.

[0025] In another embodiment of the present invention, a fixed connector 24 is provided on the vertical drive frame 21. The fixed connector 24 is used to fix the filling head 22. The two ends of the fixed connector 24 are respectively fixedly connected to the oil supply pipe 20 and the base pipe 201. The oil supply pipe 20 is connected to the oil pump in the filling machine 1 to output oil. The filling head 22 is provided with an oil inlet 222 that is slidably connected to the base pipe 201 to provide the degree of freedom to move along the axis of the base pipe 201. A first spring 202 is provided between the baffle 2221 provided on the base pipe 201 and the oil inlet 222. When the oil supply pipe 20 injects oil into the filling head 22, there is oil pressure in the filling head 22 and the base pipe 201. At this time, the pulling force of the first spring 202 is overcome, causing the two filling heads 22 to approach each other and adhere to the inner wall of the glass oil bottle 6 during oil filling.

[0026] In another embodiment provided by the present invention, such as Figure 3 , Figure 4 As shown, a back suction tube 25 is provided inside the filling head 22, and the end of the back suction tube 25 (with) Figure 10 For reference, the lower end is provided with an oil hole 251. When the filling head 22 is filling with oil, the suction pipe 25 does not perform the oil extraction step, but instead dispenses oil. When the glass oil bottle 6 is about to be filled, the filling head 22 stops dispensing oil. At this time, the oil hole 251 at the end of the suction pipe 25 briefly extracts oil to remove some of the oil from the end of the filling head 22, thereby reducing the occurrence of oil dripping.

[0027] Preferred, such as Figure 4 As shown, the filling head 22 is equipped with a pressure chamber 221, and the return suction pipe 25 includes a large end, which is located inside the pressure chamber 221. The large end of the return suction pipe 25 has an opening groove 253 corresponding to the pressure chamber 221, and an elastic plate 252 is provided on the opening groove 253. When the oil supply pipe 20 supplies oil to the filling head 22, the oil pressure in the pressure chamber 221 increases, which will squeeze the elastic plate 252 to move and deform towards the central axis of the large end of the return suction pipe 25. If the return suction pipe 25 has oil at this time, it will be squeezed into the glass oil bottle 6. When the oil supply pipe 20 stops supplying oil, the pressure in the pressure chamber 221 returns to normal. At this time, the elastic plate 252 rebounds, squeezing some oil back into the oil supply pipe 20, and causing the oil hole 251 at the end of the return suction pipe 25 to perform a brief oil extraction.

[0028] In another embodiment of the present invention, the vertical drive frame 21 is respectively provided with a fixed connector 24 and a movable connector 23 for fixing the filling head 22. When the oil filling is finished, the vertical drive frame 21 is raised, the horizontal interceptor plate 51 moves to remove the restriction on the glass oil bottle 6, and the glass oil bottle 6 is conveyed by the food-grade chain conveyor belt 3 to the next mechanism for sealing. At this time, the first (with) Figure 2 For reference, the conveyor belt transports from right to left. The first glass oil bottle 6 on the left will be carried away, while the movable connector 23 will move away from the glass oil bottle 6 as the vertical drive frame 21 moves away. This will cause the second glass oil bottle 6 to be restricted for a period of time before leaving with the food-grade chain conveyor belt 3, increasing the spacing between the glass oil bottles 6 and making it easier for subsequent mechanisms to seal them.

[0029] Preferably, the movable connector 23 includes a fixed plate 232 disposed on the vertical drive frame 21. The fixed plate 232 has a sliding groove, and a fixed oil inlet 231 is slidably connected to the sliding groove. The two ends of the fixed oil inlet 231 are respectively fixedly connected to an oil delivery pipe 20 and a base pipe 201 to provide vertical freedom between the vertical drive frame 21 and the fixed oil inlet 231, so that the filling head 22 disposed on the fixed oil inlet 231 can remain at the mouth of the glass oil bottle 6. A second spring 2311 is provided between the fixed plate 232 and the fixed oil outlet 231. The second spring 2311 is used to pull the fixed oil outlet 231 closer to the fixed plate 232. It also includes a damping element 27, on which a connecting rod 271 is provided. The connecting rod 271 is mounted on the filling machine 1. Figure 5As shown, the damping member 27 includes a first oblique angle 273 and a second oblique angle 274 for limiting the fixed oil inlet head 231. An abutment portion 272 is provided at the first oblique angle 273. When the vertical drive frame 21 presses down in the vertical direction (pressing down means moving towards the conveyor belt), the fixed oil inlet head 231 will press down along the second oblique angle 274 and deform the damping member 27. At this time, the gap between the fixed plate 232 and the fixed oil inlet head 231 is the smallest. After the fixed oil inlet head 231 passes the damping member 27, it contacts the fixed oil inlet head 231 through the abutment portion 272. When the oil filling ends, the vertical drive frame 21 is lifted in the vertical direction. At this time, the fixed connector 24 will be lifted directly. The fixed oil inlet head 231 is restricted from moving by the abutment portion 272 and the first oblique angle 273. At this time, the second spring 2311 is pulled until the pulling force drives the first oblique angle 273 to deform and pull back the fixed plate 232.

[0030] In another embodiment of the present invention, a sliding groove is provided on the vertical drive frame 21, and a locking screw 26 is provided through the sliding groove. A threaded hole is provided on the fixing plate 232 of the movable connector 23, and a threaded hole is provided on the fixed connector 24. The two locking screws 26 are respectively threaded to the fixing plate 232 and the fixed connector 24 to limit the position of the two filling heads 22.

[0031] In another embodiment of the present invention, a third oblique angle 52 is provided on the horizontal intercepting plate 51 facing the glass oil bottle 6. The third oblique angle 52 is used to insert between two arc-shaped glass oil bottles 6 to restrict the two glass oil bottles 6 that are about to be filled with oil. There are two horizontal intercepting plates 51. The glass oil bottle 6 between the two horizontal intercepting plates 51 is rotated along the axis of the glass oil bottle 6 as pushed by the rubber strip, so that the oil outlet half-hole 220 on the filling head 22 corresponds to the oil limiting recess 61 on the glass oil bottle 6.

[0032] In another embodiment of the present invention, the top limiting frame 4 includes symmetrically arranged guide plates 42, and the glass oil bottle 6 is provided with an arc-shaped head 62. The distance between the two guide plates 42 is smaller than that between the arc-shaped heads 62. Figure 2 As shown, to limit the glass oil bottle 6.

[0033] First, the food-grade conveyor belt 3 moves the glass oil bottle 6 to below the filling head 22. Then, the vertical drive frame 21 moves closer to the food-grade conveyor belt 3. At the same time, the horizontal intercepting plate 51 extends halfway to restrict the two glass oil bottles 6. Then, oil is injected. During oil injection, there is oil pressure inside the filling head 22 and the base tube 201. At this time, the pulling force of the first spring 202 is overcome, causing the two filling heads 22 to come closer to each other and fit against the inner wall of the glass oil bottle 6 during oil injection. The glass oil bottle 6 between the two horizontal intercepting plates 51 rotates with the push of the rubber strip to align the oil outlet half 220 on the filling head 22 with the oil limiting indentation on the glass oil bottle 6. Corresponding to 61, oil is discharged through the oil-limiting recess 61, and with the help of the oil outlet half-mouth 220, most of the oil is guided to flow to the inner wall of the bottle, reducing oil splashing and air bubbles. After the oil is filled, the vertical drive frame 21 is raised. At this time, the fixed connector 24 will be raised directly, while the fixed oil outlet 231 is restricted from moving by the abutment part 272 and the first oblique angle 273. At this time, the second spring 2311 is pulled until the pulling force drives the first oblique angle 273 to deform and pull back the fixed plate 232, so that the second glass oil bottle 6 will be restricted for a period of time before leaving with the food-grade chain conveyor belt 3, increasing the spacing between the glass oil bottles 6, which is convenient for subsequent mechanisms to seal.

[0034] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
