Description

Technical Field

[0001] This invention relates to the field of pet food storage tank conveying and cleaning technology, specifically a cleaning and conveying mechanism for pet food storage tanks. Background Technology

[0002] Pet food storage tanks are containers used to store pet food during or after processing. These foods are usually in solid or liquid states and are cooled and placed in large storage tanks for subsequent filling. These food storage tanks are usually made of reusable stainless steel and need to be collected centrally by a suitable conveying mechanism after storage for subsequent cleaning and reuse.

[0003] The invention disclosed in CN120135682A is a can conveying device applicable to a multi-category beverage production line. When the can is conveyed to another conveyor belt by multiple clamping blocks, the starter motor B drives the second lead screw to rotate. When the second lead screw rotates, it drives two moving plates to move through two second threaded sleeves. The two moving plates adjust the distance between the two limit plates so that the two limit plates are adapted to the size of the can, thereby preventing the can from tipping over again during the conveying process. In addition, by setting auxiliary wheels, the auxiliary wheels will contact the surface of the can to assist in the conveying of the can.

[0004] The utility model patent with announcement number CN206255501U discloses a can conveying device for a beverage production line. Instead of two chains, four sprockets, and one conveyor belt, it uses two hexagonal prisms instead of four sprockets and a metal conveyor belt instead of chains and conveyor belt. The transmission is achieved by the interlocking of the grooves on the hexagonal prisms with the hinged cylinders on the metal sheet, and the interlocking of the six facets of the hexagonal prisms with the plane of the metal sheet. The structure is simple, and the cost and failure rate are low.

[0005] However, the cleaning devices used for food and chemical storage tanks mentioned above still have the following problems in actual use: the tank is transported by a matching conveying mechanism, but this type of conveying mechanism still requires the tank to be placed with the opening facing upwards, which makes it impossible to effectively discharge the residue during the transport process. At the same time, the fluid in some storage tanks solidifies after standing, and a single cleaning mechanism cannot effectively scrape off the solidified residue, thus affecting the effectiveness and efficiency of subsequent cleaning.

[0006] Therefore, we propose a cleaning and conveying mechanism for pet food storage tanks to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a cleaning and conveying mechanism for pet food storage tanks. This addresses the problem that existing conveying mechanisms still require the tanks to be placed with their openings facing upwards, making it difficult to effectively remove residues during conveying. Additionally, in some tanks storing fluid, the fluid solidifies after settling, and a single cleaning mechanism cannot effectively scrape off the solidified residues, thus affecting the effectiveness and efficiency of subsequent cleaning.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a cleaning and conveying mechanism for a pet food storage tank, comprising a cleaning platform and a conveying platform fixedly installed at the right end of the cleaning platform, wherein conveying shafts are rotatably provided on both the left and right sides of the inside of the conveying platform via bearings, and conveying tracks are meshed on both the front and rear sides of the outer wall of the conveying shafts. A drive wheel for driving the storage tank is fixedly installed at the center of the conveying shaft on the left side; it also includes: A softening mechanism is provided in the lower center of the conveying platform, and the softening mechanism includes a softening spray disc, and a bonding scraper is provided below the softening spray disc. The cleaning platform is equipped with a cleaning mechanism, which includes a cleaning shaft, and a cleaning plate is provided at an equal angle on the outer side of the cleaning shaft.

[0009] Preferably, the softening mechanism includes a positioning bracket, which is fixedly installed on the front and rear sides of the bottom center of the conveying platform. The bottom end of the symmetrically arranged positioning bracket is rotatably provided with a drive shaft via a bearing, and the inner end of the drive shaft is fixedly provided with a pressure conveying box.

[0010] Preferably, the softening mechanism includes a carrying roller, which is rotatably mounted on the front and rear sides of the center position inside the conveying platform via bearings, and is meshed with the middle of the conveying belts on the front and rear sides. The outer ends of the symmetrically arranged carrying rollers are connected to the outer ends of the drive shaft via pulley assemblies.

[0011] Preferably, the softening mechanism includes an incomplete toothed ring, which is fixedly installed on the inner bottom of the positioning brackets on the front and rear sides. The symmetrically arranged incomplete toothed rings are sleeved and installed on the front and rear sides of the pressure supply and conveying box, and the tooth blocks of the symmetrically arranged incomplete toothed rings are distributed in a staggered manner.

[0012] Preferably, the softening mechanism includes a support base, which is fixedly installed at the center of the outer wall of the pressure conveying box at equal angles. A lifting sleeve is rotatably provided inside the support base through a bearing, and a drive gear is fixedly provided outside the lifting sleeve inside the support base. The drive gear is used to mesh with the incomplete toothed rings on the front and rear sides to rotate clockwise and counterclockwise.

[0013] Preferably, the softening mechanism includes a lifting screw threaded inside the lifting sleeve, and the outer end of the lifting screw is positioned with the bearing base by a positioning sleeve. The outer end of the lifting screw is fixedly connected to the softening spray disc, and the outer end of the lifting screw is rotatably connected to the inner end of the bonding scraper by a torsion spring. The bonding scraper is arranged in an equally angular staggered state with its upper and lower parts distributed. The rotating and hinged bonding scraper is used to enter the storage tank to scrape off the hardened residue.

[0014] Preferably, the cleaning mechanism includes a telescopic bracket, which is fixedly installed at the upper and lower ends of the cleaning shaft. The outer end of the telescopic bracket is elastically slidably connected to the inner end of the telescopic liner. The outer ends of the upper and lower telescopic liners are rotatably connected to the outer ends of the cleaning shaft plate through bearings. The outer end of the cleaning shaft plate extends to the outer end of the telescopic liner and fits against the inner wall of the storage tank.

[0015] Preferably, the cleaning mechanism includes a speed-changing shaft, which is rotatably mounted inside the cleaning platform via a bearing. The upper end of the speed-changing shaft rotates inside the cleaning shaft. A positioning gear ring is fixedly installed in the middle of the bottom surface of the cleaning platform, and a retainer is rotatably mounted at the center of the positioning gear ring.

[0016] Preferably, the cleaning mechanism includes a retainer with a drive gear rotatably disposed at the inner center position, and a driven gear rotatably disposed at the inner triangle of the retainer via a bearing, and the driven gear meshes with the drive gear. The driven gear is also meshed with the inner wall of the positioning gear ring. Meanwhile, the shaft of the drive gear is fixedly connected to the bottom end of the speed-changing shaft, and the retainer is fixedly connected to the bottom end of the cleaning shaft.

[0017] Preferably, the cleaning mechanism includes a telescopic slide rod, which rotates at an angle to the bottom surface of the lower telescopic bracket via a bearing. The inner end of the telescopic slide rod is connected to the outer wall of the transmission shaft via a main bevel gear set, and the outer end of the telescopic slide rod is connected to the bottom end of the cleaning shaft plate via a secondary bevel gear set. At the same time, a follower bracket for ensuring mutual meshing of the secondary bevel gear set is sleeved on the outer end of the telescopic slide rod and the bottom end of the cleaning shaft plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The cleaning and conveying mechanism of the pet food storage tank uses a conveyor belt and drive wheels for conveying. A softening spray disc and a scraping plate soften and remove solidified residues. After entering the cleaning platform, a rotating cleaning shaft uses centrifugal force to drive a cleaning shaft plate to adhere to the inner wall of storage tanks of different diameters. The revolving cleaning shaft plate rotates at a variable speed, achieving continuous conveying of the storage tank and improving the cleaning effect of solidified residues. The specific details are as follows: 1. The storage tank is placed with its opening facing downwards between the front and rear conveyor belts, and is then moved to the left to avoid displacement caused by the storage tank pressing on the deformation of the conveyor belts, thus ensuring the stability of the storage tank during the transportation process, so that the solidified residue can be softened and cleaned by the softening mechanism later.

[0019] The conveyor belt drives the carrying idler to rotate, which in turn drives the drive shaft and the pressure conveyor box to rotate via the pulley assembly. The carrying base on the outer wall of the pressure conveyor box, as well as the lifting sleeve and the lifting screw, revolve around each other and move synchronously with the storage tank. This causes the lifting screw to drive the softening spray disc and the bonding scraper into the interior of the storage tank, thereby softening and cleaning the solidified residue inside the storage tank.

[0020] 2. The lifting sleeve of the support base engages with the incomplete gear ring in front via a drive gear, and the lifting screw is limited by the positioning sleeve rod so that the softening spray disc and the bonding scraper can slide into the interior of the storage tank. Meanwhile, the pressure supply and delivery box delivers high-temperature and high-pressure gas into the interior of the softening spray disc to help heat up and soften the solidified residue. Then, the bonding scraper connected by the torsion spring is flipped to adapt to storage tanks with different inner diameters while cleaning and scraping away the softened residue.

[0021] The softening spray disc and the bonding scraper rotate to the top and fully enter the tank. After rotating, the drive gear disengages from the incomplete gear ring in front and meshes with the incomplete gear ring behind, causing the lifting sleeve to rotate in the opposite direction. This drives the softening spray disc and the bonding scraper to slide inward, simultaneously cleaning up the residue without affecting the continuous transport of the tank.

[0022] 3. The outer end of the drive wheel enters the storage tank, moving the storage tank into the interior of the cleaning platform. The cleaning shaft is driven to rotate by the motor, causing the telescopic liner at the outer end of the telescopic bracket to move outward by the centrifugal force of the rotation, thus fitting against the inner wall of the storage tank. The cleaning shaft plate at the outer end of the upper and lower telescopic liners revolves to clean and scrape the inner wall of the storage tank.

[0023] The cleaning shaft drives the drive gear to mesh with the driven gear to rotate. The driven gear meshes with the positioning gear ring to revolve, driving the external retainer to rotate, which in turn drives the variable speed shaft to rotate at a different speed. The main bevel gear set drives the telescopic slide rod to rotate, and the follower bracket at the outer end drives the cleaning shaft plate, which is meshed with the secondary bevel gear set, to rotate. This causes the cleaning shaft plate itself to rotate, so as to effectively clean the inner wall of the storage tank in conjunction with its revolution, thus improving the cleaning effect of solidified residues.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-12 The present invention provides the following technical solution: Example 1: In order to solve the problems existing in the cleaning of pet food storage tanks, this example provides a cleaning and conveying mechanism for pet food storage tanks, including a cleaning platform 1 and a conveying platform 2 fixedly installed on the right end of the cleaning platform 1. The conveying platform 2 has a conveying shaft 3 rotatably installed on both the left and right sides inside through bearings, and the conveying shaft 3 has a conveying track 4 meshing on both the front and rear sides of the outer wall of the conveying shaft 3.

[0028] The softening mechanism includes a positioning bracket 9, which is fixedly installed on the front and rear sides of the center of the bottom surface of the conveying platform 2. The bottom end of the symmetrically arranged positioning bracket 9 is rotatably mounted with a drive shaft 10 via a bearing, and the inner end of the drive shaft 10 is fixedly mounted with a pressure supply conveying box 11. The softening mechanism includes a carrying roller 12, which is rotatably mounted on the front and rear sides of the center position inside the conveying platform 2 via a bearing. The carrying roller 12 is meshed with the middle of the front and rear conveying tracks 4, and the outer end of the carrying roller 12 is connected to the outer end of the drive shaft 10 via a pulley assembly 13.

[0029] like Figure 1 , Figures 4-5As shown, the storage tank is placed with its opening facing downwards on the top surface of the conveyor belts 4 on both sides of the top of the conveyor platform 2. Then, the motor drives the conveyor shafts 3 on the left and right sides to rotate, so as to move the meshing conveyor belts 4 and the storage tank above them to the left. At the same time, the conveyor belts 4 drive the load-bearing rollers 12 in the middle to rotate, so as to avoid displacement caused by the storage tank pressing on the deformation of the conveyor belts 4, and ensure the stability of the storage tank during the conveying process, so as to soften and clean the solidified residues through the softening mechanism later.

[0030] Furthermore, the carrying roller 12 drives the drive shaft 10 and the pressure conveying box 11 to rotate via the pulley assembly 13 at the outer end. The pressure conveying box 11 drives the carrying base 15 on the outer wall, the lifting sleeve 16 and the lifting screw 18 to rotate, and moves synchronously with the storage tank above. This causes the lifting screw 18 to drive the softening spray disc 5 and the bonding scraper 6 at the outer end into the interior of the storage tank, thereby softening and cleaning the solidified residue inside the storage tank.

[0031] Example 2: In order to solve the problems existing in the cleaning of pet food storage tanks, this example adopts the following technical solution: a softening mechanism is provided in the lower middle part of the conveying platform 2, and the softening mechanism includes a softening spray plate 5, and a scraper 6 is provided below the softening spray plate 5; the softening mechanism includes an incomplete toothed ring 14, and the incomplete toothed ring 14 is fixedly installed on the inner bottom of the positioning brackets 9 on the front and rear sides, and the symmetrically arranged incomplete toothed rings 14 are sleeved and installed on the front and rear sides of the pressure conveying box 11, and the tooth blocks of the incomplete toothed ring 14 are distributed in a left-right staggered manner.

[0032] The softening mechanism includes a support base 15, which is fixedly installed at an angle at the center of the outer wall of the pressure supply and conveying box 11. A lifting sleeve 16 is rotatably installed inside the support base 15 via a bearing. A drive gear 17 is fixedly installed outside the lifting sleeve 16 inside the support base 15. The drive gear 17 is used to mesh with the incomplete toothed rings 14 on the front and rear sides to rotate clockwise and counterclockwise.

[0033] The softening mechanism includes a lifting screw 18 threaded inside the lifting sleeve 16. The outer end of the lifting screw 18 is positioned with the bearing base 15 by a positioning sleeve 31. The outer end of the lifting screw 18 is fixedly connected to the softening spray disc 5. The outer end of the lifting screw 18 is rotatably connected to the inner end of the bonding scraper 6 by a torsion spring. The bonding scraper 6 is arranged in an equally angular staggered state with its vertical distribution. The rotating and hinged bonding scraper 6 is used to enter the storage tank to scrape off the hardened residue.

[0034] like Figures 6-8As shown, the softening spray disc 5 and the bonding scraper 6, which rotate into the storage tank, are at the bottom. The lifting sleeve 16 inside the support base 15 meshes with the incomplete gear ring 14 at the front through the inner drive gear 17, so that the rotating lifting sleeve 16 drives the lifting screw 18. The lifting screw 18 is limited by the positioning sleeve 31 so that the outer softening spray disc 5 and the bonding scraper 6 slide into the storage tank. Meanwhile, the pressure supply and delivery box 11 delivers high-temperature and high-pressure gas into the softening spray disc 5 to help heat up and soften the solidified residue. Then, the bonding scraper 6, which is connected by a torsion spring, is flipped to adapt to storage tanks with different inner diameters while cleaning and scraping away the softened residue.

[0035] Furthermore, the lifting sleeve 16 rotates synchronously with the pressure supply and conveying box 11, and when it rotates to the highest point, it drives the softening spray disc 5 and the bonding scraper 6 to move to the outermost end. After continuing to rotate, the drive gear 17 disengages from the incomplete gear ring 14 in front and meshes with the incomplete gear ring 14 in the rear, causing the lifting sleeve 16 to rotate in the opposite direction, driving the softening spray disc 5 and the bonding scraper 6 to slide inward, and simultaneously continuing to clean up the residue without affecting the continuous conveying of the storage tank.

[0036] Example 3: To solve the problems existing in the cleaning of pet food storage tanks, this example adopts the following technical solution: A drive wheel 30 for driving the storage tank is fixedly installed at the center of the left conveying shaft 3; a cleaning mechanism is provided inside the cleaning platform 1, and the cleaning mechanism includes a cleaning shaft 7, and a cleaning shaft plate 8 is provided at equal angles on the outer side of the cleaning shaft 7; the cleaning mechanism includes a telescopic bracket 19, and the telescopic bracket 19 is fixedly installed at the upper and lower ends of the cleaning shaft 7, and the outer end of the telescopic bracket 19 is elastically slidably connected to the inner end of the telescopic liner 20, and the outer ends of the upper and lower telescopic liners 20 are rotatably connected to the outer ends of the cleaning shaft plate 8 through bearings, and the outer end of the cleaning shaft plate 8 extends to the outer end of the telescopic liner 20 and fits against the inner wall of the storage tank.

[0037] like Figures 1-3 As shown, after softening and cleaning, the storage tank continues to be conveyed to the left by the conveyor belt 4. The conveyor shaft 3 on the left side of the conveyor platform 2 drives the drive wheel 30 in the middle to rotate. The outer end of the drive wheel 30 enters the interior of the storage tank and drives the storage tank that has moved to the side to move so that the storage tank enters the interior of the cleaning platform 1. At this time, the conveyor platform 2 stops working. The telescopic liner 20 installed on the outer end of the cleaning shaft 7 inside the cleaning platform 1 is connected to the outer end of the telescopic bracket 19 by a spring. The cleaning shaft 7 is driven to rotate by a motor, so that the telescopic liner 20 at the outer end of the telescopic bracket 19 moves outward by the centrifugal force of rotation, and then fits against the inner wall of the storage tank. It revolves through the cleaning shaft plate 8 at the outer end of the upper and lower telescopic liner 20 to clean and scrape the inner wall of the storage tank.

[0038] The cleaning mechanism includes a speed-changing shaft 21, which is rotatably mounted inside the cleaning platform 1 via a bearing. The upper end of the speed-changing shaft 21 is rotatably mounted inside the cleaning shaft 7. A positioning gear ring 22 is fixedly installed in the middle of the bottom surface of the cleaning platform 1, and a retainer 23 is rotatably mounted at the center of the positioning gear ring 22.

[0039] The cleaning mechanism includes a retainer 23 in which a drive gear 24 is rotatably mounted at the center, and a driven gear 25 is rotatably mounted at the inner triangle of the retainer 23 via a bearing. The driven gear 25 is meshed with the drive gear 24 and is also meshed with the inner wall of the positioning gear ring 22. Meanwhile, the shaft of the drive gear 24 is fixedly connected to the bottom end of the speed-changing shaft 21, and the retainer 23 is fixedly connected to the bottom end of the cleaning shaft 7.

[0040] The cleaning mechanism includes a telescopic slide rod 26, which rotates at an angle to the bottom surface of the lower telescopic bracket 19 via bearings. The inner end of the telescopic slide rod 26 is connected to the outer wall of the transmission shaft 21 via a main bevel gear set 27, and the outer end of the telescopic slide rod 26 is connected to the bottom end of the cleaning shaft plate 8 via a secondary bevel gear set 28. At the same time, a follower bracket 29 is sleeved on the outer end of the telescopic slide rod 26 and the bottom end of the cleaning shaft plate 8 to ensure that the secondary bevel gear set 28 meshes with each other.

[0041] like Figures 9-12 As shown, during the rotation of the cleaning shaft 7, the driving gear 24 inside the positioning gear ring 22 meshes with the driven gear 25 to rotate. When the driven gear 25 meshes with the positioning gear ring 22, it revolves, which in turn causes the externally sleeved retainer 23 to rotate. This causes the retainer 23 to drive the fixedly connected speed-changing shaft 21 to rotate at different speeds. At the same time, the speed-changing shaft 21 drives the meshing telescopic slide rod 26 to rotate through the upper main bevel gear group 27. The telescopic slide rod 26, which can extend and slide, drives the cleaning shaft plate 8, which meshes with the secondary bevel gear group 28, to rotate through the outer follower bracket 29. This causes the cleaning shaft plate 8 to rotate on its own axis, so as to effectively clean the inner wall of the storage tank in coordination with its revolution, thereby improving the cleaning effect of solidified residues.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
