Description

Technical Field

[0001] The invention relates to the field of cargo conveying equipment, and in particular to a conveying equipment with a cleaning function. Background Art

[0002] Conveying equipment is widely used in various fields. In food production lines, conveying equipment is often used to connect the two processes before and after. For example, in the process of brewing wine lees, conveying equipment is also indispensable. Wine lees, a by-product of the brewing process, is also called wine lees or wine lees. It is mainly composed of yeast left after fermentation, unfermented sugar, alcohol and some solid substances. It is usually produced when brewing beer, wine or other alcoholic beverages.

[0003] During the conveying process of wine lees, wine lees liquid and rice often adhere to the conveyor belt, which may adhere to the surface of the conveyor roller during transmission, causing contamination to the wine lees. Therefore, the conveyor belt needs to be cleaned. In the prior art, the equipment for conveying wine lees will set a scraper on the conveyor belt to scrape off the residual wine lees stains or debris, and then use a cleaning brush to brush the conveyor belt. However, since there is a large spacing between the scraper and the brush on the conveyor belt, the conveyor belt after scraping is not quickly cleaned by the brush when passing through the brush, which may cause the stains to remain and air dry. In addition, the brush and scraper are usually only cleaned once in one cycle, which is not conducive to improving the cleanliness of the conveyor belt. In addition, the scraper and brush of some equipment need to avoid the frame of the equipment, resulting in the stains removed by the brush or scraper easily remaining at the corner of the equipment frame, which is easy to breed bacteria and is not conducive to the hygiene of the conveyor belt. Summary of the invention

[0004] The conveying device with a cleaning function of the present invention can effectively solve the problem in the above-mentioned existing transmission equipment that it is not conducive to improving the cleanliness and hygiene of the conveyor belt when in use.

[0020] Wherein, the moving direction of the scraper is perpendicular to the conveying direction of the conveyor belt;

[0021] The scraper has a scraping surface that contacts the conveyor belt, and a scraping gap is provided on the scraping surface.

[0038] In some embodiments, in the conveying direction of the conveyor belt, the conveyor belt is recessed from both sides along the middle thereof to form a concave portion for conveying, and the cleaning roller protrudes from both sides toward the middle thereof to abut against the concave portion. Thus, the concave portion can convey goods and prevent the goods from falling to the outside.

[0039] In some embodiments, a limiting roller is provided on the support frame, and the limiting roller is inclined to abut against the surface of the conveyor belt, so that the conveyor belt forms the concave portion;

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0051] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0052] The present invention relates to a conveying device with a cleaning function, which is applicable to the field of food processing and conveying technology, and is particularly applicable to the process of making wine lees. The conveying device has a normal conveying function and a cleaning function, and can ensure the cleanliness of the food processing process when in use.

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0054] Figure 1 The figure schematically shows a conveying device with a cleaning function according to an embodiment of the present invention. Figure 1As shown, the side to which the gravity direction points is the lower side, the opposite side is the upper side, the length direction of the conveying device with cleaning function is the left-right direction, and the width direction of the conveying device with cleaning function is the front-back direction. The conveying device with cleaning function includes a supporting frame 1, a conveyor belt 3 and a cleaning mechanism 4.

[0055] The support frame 1 adopts a rectangular frame structure for supporting other components. The support frame 1 can be composed of a welded frame. The bottom end of the support frame 1 has four support legs 11 for support. The support legs 11 can be placed on a horizontal storage surface. A fixed structure or a movable structure can be adopted. For example, a universal pulley is provided on the support legs 11 to facilitate movement to other positions. The support frame 1 has a hollow structure for rotatably setting a conveying roller 2. The number of conveying rollers 2 is preferably multiple. The multiple conveying rollers 2 are arranged along the length direction of the support frame 1. The axial direction of the conveying roller 2 extends in the width direction. The conveying roller 2 is specifically an electric conveying roller, which can be driven to provide power for conveying goods after being powered on. The conveyor belt 3 is sleeved on the conveyor roller 2 so that the conveyor roller 2 can drive the conveyor belt 3 to move.

[0056] Among them, Figure 2 As shown, under the drive of the conveying roller 2, the conveyor belt 3 can be rotated and conveyed along the length direction. Since the conveyor belt 3 can be cyclically rotated, the goods can be conveyed on the conveyor belt 3. In this embodiment, the upper conveying direction of the conveyor belt 3 is the conveying direction A (leftward direction), that is, the conveying direction of the goods; the lower conveying direction of the conveyor belt 3 is the conveying direction B (rightward direction), that is, the return direction of the conveyor belt 3 after conveying the goods. Further, since the conveyed goods (such as wine lees) may have a liquid form, in order to ensure the effectiveness of the conveying, the conveyor belt 3 is provided with a recess 31. The recess 31 is a recessed structure formed on the conveyor belt 3. In the conveying direction A, the conveyor belt 3 is recessed along the middle from both sides of the width direction to form the recess 31 for conveying the goods. When viewed from the side, the recess 31 is distributed on the upper and lower sides of the conveyor belt 3. The recess 31 makes the conveyor belt 3 form a structure with high sides and low middle, that is, the height of the front and rear sides is greater than the height in the middle, and the middle part of the conveyor belt 3 remains flat, so that the goods can be limited during transportation.

[0057] Specifically, Figure 3As shown, the concave portion 31 is formed by the structural limitation of the limiting roller 12 and the conveying roller 2. The limiting roller 12 is rotatably arranged on the supporting frame 1. The number of the limiting rollers 12 is arranged in a mirror-symmetrical manner in the up-down direction and the front-back direction. The limiting roller 12 is arranged obliquely on the supporting frame 1, that is, the axis of the limiting roller 12 intersects with the axial direction of the conveying roller 2. In order to adapt to the shape of the conveyor belt 3, the conveying roller 2 also has a structure that is wide on both sides and narrow in the middle. The diameter of the middle part of the conveying roller 2 is smaller than the diameter of the two side parts thereof. Furthermore, the conveying roller 2 is also provided with abutting inclined surfaces 21, which are arranged in a mirror-symmetrical manner on both sides in the front-back direction. The inclination of the abutting inclined surfaces 21 is the same as that of the limiting roller 12, and the position of the limiting roller 12 is closer to the abutting inclined surfaces 21. When the conveyor belt 3 is sleeved on the conveyor roller 2, the inner side of the conveyor belt 3 contacts the abutting inclined surface 21, and the limiting rollers 12 on the upper and lower sides can cooperate with the abutting inclined surface 21 to limit the conveyor belt 3. The limiting rollers 12 on the left and right sides are symmetrically limited, so that the conveyor belt 3 is subjected to force between the abutting inclined surface 21 and the limiting rollers 12. In this way, the conveyor belt 3 is recessed toward the middle to form a recess 31. When conveying goods through the recess 31, it can effectively prevent the goods from falling from the conveyor belt 3, which is conducive to improving the conveying effectiveness of the conveyor belt 3.

[0058] like Figure 4 As shown, the cleaning mechanism 4 is used to clean the conveyor belt 3 during transportation, and can simultaneously perform multiple and alternating cleaning and scraping actions on the conveyor belt 3. The cleaning mechanism 4 is integrated on the lower side (bottom) of the support frame 1 and is not easy to interfere with other transport components. Specifically, the cleaning mechanism 4 includes a water collecting frame 41, a flushing unit, a scraping device, a cleaning roller 44 and a transmission unit.

[0059] The water collecting frame 41 adopts a frame with a hollow structure inside, which is used to collect stains or debris (such as lees liquid and debris formed by rice) removed from the conveyor belt 3. The water collecting frame 41 can be fixedly connected or detachably connected to the bottom of the supporting frame 1. The flushing unit, scraping device, cleaning roller 44 and transmission unit are all integrated on the water collecting frame 41. The above-mentioned mechanisms are mainly located on the left part of the water collecting frame 41. The right part of the water collecting frame 41 is an open structure, which is convenient for cleaning and detecting the internal situation. The bottom of the water collecting frame 41 is provided with a water outlet 411. Preferably, the bottom of the water collecting frame 41 is concave and gathered at the water outlet 411, so that the debris collected in the water collecting frame 41 can be discharged from the water outlet 411 by gravity. The outer side of the water outlet 411 is usually connected to a conduit to facilitate drainage to the outside, or reuse of debris processing, etc.

[0060] like Figure 4As shown, the flushing unit is used to flush the conveyor belt 3 and is the first step in the cleaning process of the conveyor belt 3. The flushing unit is located on the leftmost side of the water collecting frame 41. The flushing unit includes a first flusher 421, a second flusher 422, a pressurizing device and a water baffle 424. The first flusher 421 and the second flusher 422 extend in the width direction, and a plurality of nozzles are provided on the first flusher 421 and the second flusher 422, and the nozzles face upward so as to directly act on the conveyor belt 3. The pressurizing device is specifically a pressurizing pump 423, wherein an external connecting frame 412 extends on the left side of the water collecting frame 41, and the pressurizing pump 423 is installed on the external connecting frame 412, and the output end of the pressurizing pump 423 is connected to the first flusher 421 and the second flusher 422, the first flusher 421 is connected to a storage tank for cleaning liquid, and the second flusher 422 is connected to a storage tank for clean water. When the pressurizing pump 423 starts working, it can pressurize and drive the first flusher 421 to spray cleaning liquid onto the conveyor belt 3, and drive the second flusher 422 to spray clean water upward to flush the conveyor belt 3. In the conveying direction B, the first flusher 421 is located on the upstream side of the second flusher 422, and the second flusher 422 is located on the upstream side of the cleaning roller 44. Therefore, the conveyor belt 3 will pass through the first flusher 421, the second flusher 422 and then enter the cleaning roller 44 in sequence, and gradually complete the cleaning operation in sequence. The number of water baffles 424 can be set to two, which are fixed and closed on the inner wall of the water collecting frame 41, so that the first flusher 421 and the second flusher 422 are exposed between the water baffles 424. The water baffles 424 have arc walls to form an internal hollow structure, which can enclose the first flusher 421 or the second flusher 422 on both sides, so that the first flusher 421 and the second flusher 422 directly act on the surface of the conveyor belt 3, and the cleaning liquid of the first flusher 421 is blocked by the water baffles 424 from entering the conveyor belt 3 from the front and rear sides, avoiding contamination of the wine lees, which is conducive to improving the hygienic degree of conveying the conveyor belt 3.

[0061] The cleaning roller 44 is rotatably arranged on the water collecting frame 41, and is used to abut against the surface of the conveyor belt 3 and clean the surface of the conveyor belt 3 by rolling. The axis of the cleaning roller 44 extends in the width direction. The cleaning roller 44 is provided with a plurality of cleaning rollers capable of performing multiple cleaning actions on the conveyor belt 3. In this embodiment, the number of cleaning rollers 44 is set to 4 and is evenly arranged along the conveying direction B. In order to adapt to the structure of the concave portion 31 of the conveyor belt 3, the cleaning roller 44 adopts a structure with narrow sides and wide middle, that is, the diameters of the two sides of the cleaning roller 44 are greater than the diameter of the middle part so that the cleaning roller 44 forms a convex structure, and the axial length of the middle part of the cleaning roller 44 is adapted to the width size of the concave portion 31. Preferably, the cleaning roller 44 needs to be cleaned again when the conveyor belt 3 undergoes the last scraping action, that is, the cleaning action of the cleaning roller 44 is used as the last surface contact treatment. In this embodiment, the cleaning roller 44 is firstly moved after the conveyor belt 3 is sprayed with liquid, and the subsequent cleaning roller 44 is used to end the cleaning action after alternate cleaning to ensure the cleanliness of the conveyor belt 3. The cleaning roller 44 is mainly rotated by the transmission unit.

[0062] like Figure 5 , Figure 6As shown, the transmission unit is used to provide power for the operation of the cleaning roller 44 and the scraping device, and the transmission unit includes a driving device 451, a synchronous wheel 452, a driven wheel 453, a synchronous belt 454 and a pressure plate 455. The driving device 451 is arranged on one side of the water collecting frame 41, and is used to provide a power source for the transmission unit. The driving device 451 is specifically a driving motor. The output end of the driving device 451 is connected to the cleaning roller 44, so that the cleaning roller 44 is driven to rotate. The synchronous wheel 452 is coaxially arranged on the cleaning roller 44. Two synchronous wheels 452 are respectively arranged at both ends of a single cleaning roller 44. The synchronous belt 454 is connected to two adjacent synchronous wheels 452 in transmission. When the cleaning roller 44 rotates, the synchronous belt 454 can be driven to rotate through the synchronous wheel 452, and the synchronous belt 454 drives another cleaning roller 44 to rotate, wherein the two adjacent cleaning rollers 44 are driven by at least one synchronous belt 454, so that all cleaning rollers 44 can rotate. The driven wheel 453 is arranged in the synchronous belt 454. The driven wheel 453 is preferably a gear structure, which can be meshed with the gear rack of the synchronous belt 454 to rotate. The driven wheel 453 is used to drive the scraping device to move to perform the scraping action. The pressure plate 455 is arranged on the inner wall of the water collecting frame 41. The pressure plate 455 adopts a plate structure, which extends along the width direction and can cover part of the synchronous belt 454. The pressure plate 455 abuts against the upper and lower sides of the synchronous belt 454, that is, two pressure plates 455 are matched on one synchronous belt 454. The pressure plate 455 is used to abut against and limit the outward expansion of the synchronous belt 454, so that the synchronous belt 454 can continue to maintain contact, fit or mesh with the synchronous wheel 452 and the driven wheel 453, so as to improve the effectiveness of the transmission unit in transmitting power, so that the synchronous belt 454 is not easy to disengage or slip during transmission. In some embodiments, the thickness of the pressure plate 455 may be appropriately increased or a movable or detachable structure may be provided, so that the pressure plate 455 can adjust the tightness of the synchronous belt 454 when it abuts against the synchronous belt 454 .

[0063] like Figure 5 , Figure 6As shown, the scraping device is used to perform a scraping action on the surface of the conveyor belt 3. There are multiple scraping devices, and the multiple scraping devices are evenly arranged in the conveying direction B to perform multiple scraping actions on the conveyor belt 3. In the conveying direction B, the scraping device and the cleaning roller 44 are arranged adjacent to each other and arranged alternately (staggered) at intervals to achieve alternate cleaning and scraping actions on the conveyor belt 3. Specifically, the scraping device includes a reciprocating screw 431, a limit slide 432 and a driving block 433. The reciprocating screw 431 has a threaded structure, which is rotatably arranged on the water collecting frame 41. The shaft end of the reciprocating screw 431 is coaxially mounted with a driven wheel 453, and the reciprocating screw 431 is driven to rotate by the rotation of the driven wheel 453. The limit slide bar 432 adopts a slide bar structure fixedly set on the inner wall of the water collecting frame 41. The number of limit slide bars 432 is set to two and they are adjacently set on both sides of the reciprocating screw 431. The limit slide bar 432 is used to limit and guide the driving block 433. The limit slide bar 432 and the driving block 433 are connected through the shaft hole. The driving block 433 adopts a block structure. The driving block 433 is provided with a plurality of driving blocks 433 and arranged along the axial direction (width direction) of the reciprocating screw 431. The driving block 433 is movably set on the reciprocating screw 431, wherein the driving block 433 is provided with a threaded through hole, and the driving block 433 can be threadedly screwed with the reciprocating screw 431 through the threaded through hole. The driving block 433 is also provided with a through hole structure, which can slide with the limit slide bar 432. In addition, a scraper 434 is provided on each driving block 433. The scraper 434 adopts a "door" type structure and is used to scrape off debris on the surface of the conveyor belt 3. The upper side of the scraper 434 has a scraping surface 435. The scraping surface 435 can be a plane or an inclined surface. A scraping gap 436 is provided on the scraping surface 435. The scraping gap 436 is a hollow structure. The scraping gap 436 can divide the scraping surface 435 into two surfaces.

[0064] When in use, the synchronous belt 454 drives the driven wheel 453 to rotate, and the driven wheel 453 drives the reciprocating screw 431 to rotate, so that the driving block 433 moves along the limiting slide rod 432 and the reciprocating screw 431, and the scraping surface 435 can abut against the surface of the conveyor belt 3. Driven by the driving block 433, the scraper 434 makes the scraping surface 435 perform a scraping action on the conveyor belt 3. The debris on the conveyor belt 3 can fall from the scraping gap 436 and is not easy to adhere to the scraper 434 repeatedly. The reciprocating movement of multiple scrapers 434 on the conveyor belt 3 is conducive to effectively scraping off the debris on the upper surface of the conveyor belt 3 to improve the cleaning degree.

[0065] Further, such as Figure 4As shown, an exhaust fan 413 for driving a hot air flow is provided on the water collecting frame 41. The number of exhaust fans 413 is provided in plurality and arranged along the width direction. The position of the exhaust fan 413 is closer to the right edge of the water collecting frame 41, that is, in the transport B direction, the exhaust fan 413 is arranged on the downstream side of the cleaning roller 44, so the conveyor belt 3 passes through the drying effect of the exhaust fan 413 after the cleaning action and scraping action of the cleaning roller 44 and the scraping device. Preferably, the exhaust fan 413 can drive the hot air flow to blow toward the conveyor belt 3. The exhaust fan 413 can be a hot fan or a driving fan with a heater, etc. The exhaust fan 413 drives the air flow to flow toward the conveyor belt 3, so that the conveyor belt 3 can be quickly dried when passing through, so as to ensure the dryness of the conveyor belt 3 before transportation, which is beneficial to the cleanliness of the conveyor belt 3.

[0066] Working principle: Taking a single cycle of the conveyor belt 3 as an example, the conveyor roller 2 is started to drive the conveyor belt 3 to transport. The upper side (recess 31) of the conveyor belt 3 can transport goods (such as wine lees) along the conveying direction A. The lower side of the conveyor belt 3 is the return circulation part, which can be cleaned and scraped by the cleaning mechanism 4. In the conveying direction B, the conveyor belt 3 first passes through the first flushing device 421 and the second flushing device 422 in turn. Under the pressure of the pressure pump, the first flushing device 421 sprays cleaning liquid to the conveyor belt 3, and the second flushing device 422 sprays cleaning liquid to the conveyor belt 3. The conveyor belt 3 is flushed, and the driving device 451 is started to rotate the cleaning roller 44. The cleaning roller 44 drives the reciprocating screw 431 to rotate through the cooperation of the synchronous belt 454 and the driven wheel 453, so that the scraper 434 moves. The conveyor belt 3 passes through the cleaning roller 44 and the scraper 434 and performs multiple alternating cleaning and scraping actions at the same time, so that the debris on the surface of the conveyor belt 3 is removed and collected in the water collecting frame 41, and finally the conveyor belt 3 is dried by the action of the exhaust fan 413, and the conveyor belt 3 enters the next cycle.

[0067] The above description is only a preferred embodiment of the present invention. In order to make the description concise, not all possible combinations of the various technical features in the above embodiment are described, and the present invention is not limited in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
