Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and more specifically, to an automated conveying device for meat product processing. Background Technology

[0002] Meat products refer to cooked or semi-cooked meat products made primarily from poultry and livestock meat and seasoned with spices. Meat products are generally divided into two categories: raw products and cooked products. Raw products refer to meat products that have not been cooked and need to be cooked before consumption, such as cured meat, seasoned beef ribs, Cantonese sausages, and salted meat. Cooked products refer to meat products that have been cooked and can be eaten directly, such as braised beef, ham sausages, roast duck, and dried meat.

[0003] In the process of processing meat products, enterprises usually use conveying devices to transport raw meat from the receiving position to various work stations such as cutting, marinating, and cooking. In order to ensure the hygiene of meat product processing, in the existing technology, a cleaning structure is often set in the conveying device used to transport meat products. For example, a rigid or flexible scraper is used to scrape off solid impurities such as meat scraps and bone fragments attached to the surface of the conveyor belt, thereby reducing the accumulation of contaminants on the conveyor belt and improving the hygiene during transportation.

[0004] In practical applications, solid impurities and grease often coexist on the conveyor belt. However, due to the stickiness of grease, simple scraping or water washing has very limited cleaning effect. The residual grease will gradually dry and harden on the surface of the conveyor belt, which not only affects the normal operation of the subsequent scrapers, but also easily attracts new debris, thus forming stubborn stains that are more difficult to clean. Furthermore, it will breed bacteria and cause secondary contamination to the conveyed raw meat. Summary of the Invention

[0005] This invention proposes an automated conveying device for meat processing, which solves the problem in the prior art that solid impurities and grease attached to the conveyor belt during the conveying of raw meat not only affect hygiene conditions but also breed bacteria, easily causing secondary contamination of the raw meat.

[0006] The technical solution of the present invention is as follows: An automated conveying device for meat product processing includes a conveying unit comprising a conveyor frame, idlers, drive rollers, a drive motor, a conveyor belt, and a tensioning mechanism, and further includes: The mounting frame is fixedly installed on the conveyor frame; A sliding pressure plate is fixedly installed on the inner top wall of the mounting frame, and the bottom of the sliding pressure plate slides against the conveyor belt. A scraping and cleaning assembly is disposed inside the mounting frame and is used to scrape off and clean solid impurities adhering to the conveyor belt. The mounting frame has several collection racks spaced apart inside; Each of the collection racks is equipped with a grease cleaning component, which is used to absorb and treat animal grease adhering to the conveyor belt.

[0007] To remove solid impurities from the conveyor belt, the scraping and cleaning assembly includes: The mounting frame is fixed and inclined inside the mounting frame, and a flexible scraper is provided on the mounting frame. The free end of the flexible scraper abuts against the conveyor belt. A cleaning mechanism is provided inside the mounting frame and is used to clean away solid impurities when the flexible scraper removes solid impurities from the conveyor belt.

[0008] When handling solid impurities on a conveyor belt, it is necessary to remove the solid impurities. The cleaning mechanism includes: A water supply pipe is fixedly installed inside the mounting frame; The nozzles are connected at equal intervals on the water supply pipe, and the output end of each nozzle points to the free end of the flexible scraper.

[0009] The mounting frame has a water collection shell fixedly installed inside, and the water collection shell has several filter screens inside. Each filter screen is arranged at an angle, and the drain end of the water collection shell is connected to a drain pipe.

[0010] To remove grease and impurities from the conveyor belt, the grease cleaning assembly includes: A pusher bracket is slidably installed inside each of the collection racks; A driving component is installed at the bottom of each collection rack, and the output end of the driving component is fixedly connected to the push bracket. An oil suction mechanism is installed on each of the push brackets to absorb the grease adhering to the conveyor belt; An oil discharge mechanism is installed on each of the push brackets to discharge the grease absorbed by the oil suction mechanism.

[0011] To absorb grease on the conveyor belt, the oil absorption mechanism includes: Inner sleeve and outer sleeve, each of the push brackets is fixedly provided with an inner sleeve, and each inner sleeve is sealed and rotatably provided with an outer sleeve; Oil-absorbing sponge, each of the outer sleeves is covered with the oil-absorbing sponge; The sliding pressure plate has several clearance grooves at its bottom, and each clearance groove corresponds to one of the outer sleeves.

[0012] Furthermore, it also includes: An internal gear is coaxially fixed inside each of the outer sleeves; Each inner sleeve is equipped with a drive motor, and the output end of each drive motor is coaxially fixed with a drive gear, which meshes with the inner gear.

[0013] In order to remove the grease absorbed by the oil-absorbing sponge, the oil-draining mechanism includes: An arc-shaped support frame is fixedly installed on each of the aforementioned push brackets; Each of the arc-shaped support frames has several pressure rollers mounted at equal angles in an arc shape, and the pressure rollers abut against and compress the oil-absorbing sponge; Each of the collection racks is connected to a drain pipe at its drain end.

[0014] The working principle and beneficial effects of this invention are as follows: 1. In this invention, as the conveyor belt moves, the free end of the flexible scraper comes into contact with the conveyor belt to scrape off solid impurities such as meat scraps, bone scraps, and blood. At the same time, the nozzle on the water supply pipe points to the free end of the flexible scraper, and the sprayed water flows away the debris on the scraper and wets the surface of the conveyor belt to prevent grease from drying. The wastewater after rinsing and the mixed solid impurities are separated by the filter screen in the water collection shell, thereby avoiding the accumulation of solid impurities on the conveyor belt and facilitating the subsequent cleaning of grease on the conveyor belt.

[0015] 2. In this invention, the drive motor drives the outer sleeve and oil-absorbing sponge to rotate through the meshing of the drive gear and the inner gear. Since the rotation direction of the oil-absorbing sponge is opposite to the movement direction of the conveyor belt, reverse relative friction can be generated, which facilitates the adsorption of oil film on the conveyor belt by the oil-absorbing sponge and improves the adsorption capacity of oil film on the conveyor belt.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 5As shown, this embodiment proposes an automated conveying device for meat product processing, including a conveying unit consisting of a conveyor frame 1, idler rollers 2, drive rollers 3, a drive motor 4, a conveyor belt 5, and a tensioning mechanism 6. The idler rollers 2, drive rollers 3, and tensioning mechanism 6 jointly support and tension the conveyor belt 5. When meat needs to be conveyed, the drive motor 4 is activated to drive the drive rollers 3 to rotate, thereby moving the meat to the next stage via the conveyor belt 5. The direction in which the conveyor belt 5 conveys the raw meat is as follows: Figure 1 , Figure 2 As indicated by arrow A, the system also includes a mounting frame 7, a sliding pressure plate 8, a scraping and cleaning assembly, a collection rack 9, and a grease cleaning assembly. The mounting frame 7 is fixedly mounted on the conveyor frame 1. A sliding pressure plate 8 is fixedly mounted on the inner top wall of the mounting frame 7. The bottom of the sliding pressure plate 8 slides against the conveyor belt 5. The scraping and cleaning assembly is located inside the mounting frame 7 and is used to scrape and clean solid impurities adhering to the conveyor belt 5. The scraping and cleaning assembly includes a clamping frame 101 and a cleaning mechanism, such as... Figures 3 to 5 As shown, a clamping frame 101 is fixed and inclined inside the mounting frame 7. A flexible scraper 102 is provided on the clamping frame 101. The free end of the flexible scraper 102 abuts against the conveyor belt 5. A cleaning mechanism is provided inside the mounting frame 7 and is used to clean off solid impurities when the flexible scraper 102 scrapes off solid impurities on the conveyor belt 5.

[0021] During the meat conveying process, solid impurities such as blood, meat scraps, bone fragments, and grease will adhere to the conveyor belt 5. In order to prevent these impurities from contaminating the conveyor belt 5 and the raw meat, and to slow down the spoilage of the raw meat, the conveyor belt 5 also needs to be cleaned.

[0022] Figures 3 to 5 The direction indicated by the arrow in the middle B is the moving direction of the conveyor belt 5. When the conveyor belt 5 enters the installation frame 7, the conveyor belt 5 slides into contact with the bottom side of the sliding pressure plate 8. At this time, the flexible scraper 102 on the clamping frame 101 abuts against the side of the conveyor belt 5 that is in contact with the raw meat. As the conveyor belt 5 moves, the attached impurities can be scraped off by the flexible scraper 102. At the same time, the cleaning mechanism is activated to clean off the scraped solid impurities.

[0023] After the solid impurities are scraped off, the conveyor belt 5 enters the working area of ​​the grease cleaning component. Under the action of the grease cleaning component, the grease on the conveyor belt 5 can be cleaned off, thereby preventing these impurities from adhering to the conveyor belt 5 and preventing impurities from contaminating the conveyor belt 5 and the raw meat during the conveying process.

[0024] like Figure 4 , Figure 5As shown, the cleaning mechanism includes a water supply pipe 103 and nozzles 104. The water supply pipe 103 is fixedly installed inside the mounting frame 7, and several nozzles 104 are connected at equal intervals on the water supply pipe 103. The output end of the nozzles 104 points to the free end of the flexible scraper 102. A water collection shell 105 is fixedly installed inside the mounting frame 7, and several filter screens 106 are installed inside the water collection shell 105. Each filter screen 106 is arranged at an angle. When the filter screen 106 filters solid impurities, the filtered impurities will accumulate at the lower position of the filter screen 106, thereby avoiding clogging of the filter screen 106. The drain end of the water collection shell 105 is connected to a drain pipe 107.

[0025] Before use, connect the external water source to the water supply pipe 103. After the flexible scraper 102 scrapes off the impurities attached to the conveyor belt 5, turn on the nozzle 104. Water is sprayed through the water supply pipe 103 and the nozzle 104 to the contact position between the flexible scraper 102 and the conveyor belt 5. As the conveyor belt 5 runs, the flexible scraper 102 scrapes off solid impurities. The sprayed water also washes away the debris on the scraper and wets the surface of the conveyor belt 5 to prevent grease from drying. The wastewater mixed with solid impurities after rinsing falls into the water collection shell 105 under the guidance of the mounting frame 7. When this wastewater passes through the inclined filter screen 106, the solid impurities are intercepted. The filtered wastewater is discharged from the drain pipe 107 and enters the wastewater treatment equipment.

[0026] It should be noted that the water in the water inlet pipe 103 is preferably hot water, which facilitates the scraping off of some of the solid grease in the solid impurities, so that only a softened oil film remains on the conveyor belt after the impurities are scraped off by the flexible scraper 102, making cleaning easier.

[0027] The mounting frame 7 has several collection racks 9 spaced apart inside. Each collection rack 9 is equipped with a grease cleaning component for absorbing and treating animal grease adhering to the conveyor belt 5. The grease cleaning component includes a pusher bracket 201, a drive component 202, an oil suction mechanism, and an oil discharge mechanism. Figures 4 to 9 As shown, each collection rack 9 has a sliding pusher 201 installed inside, and each collection rack 9 has a drive component 202 installed at the bottom. The drive component 202 is preferably an electric cylinder. The output end of the drive component 202 is fixedly connected to the pusher 201. Each pusher 201 is equipped with an oil suction mechanism for adsorbing the grease attached to the conveyor belt 5. Each pusher 201 is also equipped with an oil discharge mechanism for discharging the grease adsorbed by the oil suction mechanism.

[0028] When it is necessary to clean the grease on the conveyor belt 5, the drive unit 202 pushes the push bracket 201 to move upward, so that the oil suction mechanism contacts the bottom of the conveyor belt 5. As the conveyor belt 5 runs, the oil suction mechanism automatically absorbs the grease. After the oil suction mechanism absorbs the grease, the oil discharge mechanism can squeeze the oil suction mechanism to squeeze out the grease it has absorbed and let it enter the collection rack 9. Then the cleaned grease is discharged.

[0029] The oil suction mechanism includes an inner sleeve 203, an outer sleeve 204, an oil-absorbing sponge 205, and a relief groove 206, such as Figures 6 to 9 As shown, each pusher bracket 201 is fixedly equipped with an inner sleeve 203, and each inner sleeve 203 is sealed and rotatably equipped with an outer sleeve 204. Each outer sleeve 204 is covered with an oil-absorbing sponge 205, which is cylindrical and replaceable. The bottom of the sliding pressure plate 8 is provided with several clearance grooves 206, which correspond one-to-one with several outer sleeves 204. The clearance grooves 206 provide a space for the conveyor belt 5 to accommodate it, preventing excessive compression that could deform the conveyor belt 5. It also includes an internal gear 207 and a drive motor 208, as shown... Figure 8 , Figure 9 As shown, each outer sleeve 204 has an internal gear 207 coaxially fixed inside, each inner sleeve 203 has a drive motor 208 inside, and the output end of each drive motor 208 has a drive gear 209 coaxially fixed inside. The drive gear 209 meshes with the internal gear 207.

[0030] When the drive unit 202 pushes the push bracket 201 to rise until the oil-absorbing sponge 205 on the outer sleeve 204 contacts the bottom surface of the conveyor belt 5, when the oil-absorbing sponge 205 presses against the conveyor belt 5 and causes it to deform to a certain extent, the relief groove 206 provides a space to accommodate the deformed part of the conveyor belt 5, and at the same time facilitates increasing the contact area between the oil-absorbing sponge 205 and the conveyor belt 5, thereby improving the adsorption efficiency of the oil film attached to the conveyor belt 5.

[0031] During the process of adsorbing grease on the conveyor belt 5, the drive motor 208 is turned on to drive the drive gear 209 to rotate. The drive gear 209, through its cooperation with the inner gear 207, drives the outer sleeve 204 to rotate on the inner sleeve 203, thereby driving the oil-absorbing sponge 205 to rotate. The rotation direction of the oil-absorbing sponge 205 is opposite to the movement direction of the conveyor belt 5. Thus, as the conveyor belt 5 moves, relative friction occurs between the oil-absorbing sponge 205 and the conveyor belt 5, which facilitates the adsorption of grease on the conveyor belt 5.

[0032] The oil discharge mechanism includes an arc-shaped support frame 210, a pressure roller 211, and a drain pipe 212, such as Figure 7 , Figure 8As shown, each pusher bracket 201 is fixedly equipped with an arc-shaped support frame 210, and each arc-shaped support frame 210 is equipped with several pressure rollers 211 that rotate at equal angles in an arc shape. The pressure rollers 211 abut against and compress the oil-absorbing sponge 205, and the drain end of each collection rack 9 is connected to a drain pipe 212.

[0033] When the oil-absorbing sponge 205 is saturated, as the oil-absorbing sponge 205 rotates, multiple pressure rollers 211 on the arc-shaped support frame 210 press against and compress the oil-absorbing sponge 205, squeezing out the grease absorbed inside the sponge. The squeezed-out grease flows into the drain pipe 212 at the bottom of the collection frame 9 and is discharged. Since the pressure rollers 211 are installed in a rotating manner, they can roll along with the rotation of the oil-absorbing sponge, thereby reducing friction and facilitating the squeezing out of the grease inside the oil-absorbing sponge 205.

[0034] When conveying raw meat using a conveying device, the drive motor 4 is turned on to drive the transmission roller 3 to rotate, thereby moving the meat to the next stage via the conveyor belt 5. As the conveying proceeds, solid impurities such as blood, meat scraps, bone fragments, and grease in the raw meat will adhere to the conveyor belt 5. In order to prevent these impurities from contaminating the conveyor belt 5 and the raw meat and to slow down the spoilage of the raw meat, the conveyor belt 5 also needs to be cleaned.

[0035] Before cleaning the conveyor belt 5, connect the external water source to the water supply pipe 103. After the conveyor belt 5 enters the installation frame 7, it slides into contact with the bottom of the sliding pressure plate 8. At this time, the flexible scraper 102 on the clamping frame 101 abuts against the side of the conveyor belt 5 that is in contact with the raw meat. As the conveyor belt 5 moves, the attached impurities can be scraped off by the flexible scraper 102. At the same time, the nozzle 104 is turned on, and water is sprayed through the water supply pipe 103 and the nozzle 104 onto the contact position between the flexible scraper 102 and the conveyor belt 5. Spraying is performed, and as the conveyor belt 5 runs, the flexible scraper 102 scrapes off solid impurities. The sprayed water also washes away the debris on the scraper and wets the surface of the conveyor belt 5 to prevent grease from drying. The wastewater mixed with solid impurities after rinsing falls into the water collection shell 105 under the guidance of the mounting frame 7. When this wastewater passes through the inclined filter screen 106, the solid impurities are intercepted. The filtered wastewater is discharged from the drain pipe 107 and can be collected or treated.

[0036] When it is necessary to clean the grease on the conveyor belt 5, the drive unit 202 pushes the push bracket 201 to move upward, so that the oil-absorbing sponge 205 contacts the bottom of the conveyor belt 5. When the oil-absorbing sponge 205 presses against the conveyor belt 5 and causes it to deform to a certain extent, the clearance groove 206 provides a space to accommodate the deformed part of the conveyor belt 5, and at the same time facilitates increasing the contact area between the oil-absorbing sponge 205 and the conveyor belt 5, thereby improving the adsorption efficiency.

[0037] During the process of absorbing grease on the conveyor belt 5, the drive motor 208 is turned on to drive the drive gear 209 to rotate. The drive gear 209, through its cooperation with the inner gear 207, drives the outer sleeve 204 to rotate on the inner sleeve 203, thereby driving the oil-absorbing sponge 205 to rotate. The rotation direction of the oil-absorbing sponge 205 is opposite to the movement direction of the conveyor belt 5. Thus, as the conveyor belt 5 moves, relative friction occurs between the oil-absorbing sponge 205 and the conveyor belt 5, which facilitates the absorption of grease on the conveyor belt 5. When the oil-absorbing sponge 205 is saturated, as the oil-absorbing sponge 205 rotates, multiple pressure rollers 211 on the arc-shaped support frame 210 press against and compress the oil-absorbing sponge 205, squeezing out the grease absorbed inside the sponge. The squeezed-out grease flows into the drain pipe 212 at the bottom of the collection frame 9 and is discharged, thereby preventing these impurities from adhering to the conveyor belt 5 and preventing impurities from contaminating the conveyor belt 5 and the raw meat during the conveying process.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.
