Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly to a raw material feeding device for food processing. Background Art

[0002] When processing rice cracker food, the raw materials are usually stored frozen, and then when processing, the frozen raw materials are taken out and conveyed to the next process through a conveyor. Since the ice water on the surface of the frozen raw materials will flow onto the surface of the conveyor belt during conveying, and since the raw materials absorb heat when thawing, the ice water on the surface of the conveyor belt may freeze during continuous conveying, forming a certain thickness of ice layer on the surface of the conveyor belt. When the ice layer adheres to the surface of the conveyor belt, it will cause the raw materials to slip on the surface of the conveyor belt. In addition, when the ice layer continuously contacts the frozen raw materials, the thickness of the ice layer will become thicker and thicker, affecting the use of the conveyor.

[0003] After retrieval, a raw material feeding device for food processing is disclosed in Chinese Patent Publication No. CN118811419A, which includes a feeding mechanism, which includes a frame, conveying roller assemblies arranged on both sides of the top of the frame, a conveyor belt arranged on the conveying roller assemblies, a driving motor arranged on one side of the frame and connected to the conveying roller assemblies, and a control box arranged on the frame, a cleaning mechanism, which includes a speed sensing assembly arranged at one end of the frame away from the driving motor, and a scraper assembly arranged below the conveyor belt and connected to the speed sensing assembly. The control box controls the rotation speed of the driving motor to adjust the conveying speed of the conveyor belt, and the speed sensing assembly is connected to the conveying roller assemblies.

[0004] In the above-mentioned prior art, the blood or ice layer on the surface of the conveyor belt is scraped off by a scraper. However, since some ice layers may be relatively thick, when the scraper contacts the ice layer, the resistance received is relatively large, which easily causes the conveyor belt to wrinkle and the conveyor belt to become loose. Therefore, it is necessary to further improve the feeding device in the prior art. Summary of the Invention

[0005] The purpose of the present invention is to provide a raw material feeding device for food processing to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A raw material feeding device for food processing, including a conveying mechanism provided with a conveyor belt, the conveying mechanism is installed on the top of the frame, and further includes:

[0008] A fixing frame installed on the frame, and two supports are connected to the outer wall of the fixing frame;

[0009] A sliding column that is horizontally slidably disposed on the support, and a scraper is fixedly connected to one ends of the two sliding columns corresponding to the feeding side of the conveyor belt, and the top surface of the scraper is in sliding contact with the lower surface of the conveyor belt;

[0010] An ice knocking mechanism slidably connected to an outer wall of the scraper facing the discharging side of the conveyor belt, and the ice knocking mechanism is used to drive the ice knocking mechanism to reciprocate up and down when the sliding column moves towards the feeding side of the conveyor belt.

[0011] Through the above technical solution, the top of the scraper contacts the lower surface of the conveyor belt, so that the ice layer on the surface of the conveyor belt can contact the surface of the scraper. And as the conveyor belt runs, the ice layer will be blocked by the scraper, so that the ice layer can be separated from the surface of the conveyor belt. When the adhesion degree between the ice layer and the conveyor belt is large and the ice layer is not easily separated from the surface of the conveyor belt, the scraper will be squeezed by the ice layer, and then move in the direction of the feeding side of the conveyor belt, so that the sliding column moves horizontally on the support, and at the same time, the ice knocking mechanism is triggered to act. The ice knocking mechanism generates a repeated knocking force on the surface of the ice layer near the top of the scraper, so that the ice layer is broken when receiving the knocking force, and then the scraper can scrape off the ice layer. In addition, because the scraper can passively generate a certain degree of horizontal movement through the sliding of the sliding column on the support, and during the horizontal movement, it can continuously squeeze the ice layer and give the knocking mechanism enough time to knock the ice layer near the top of the scraper, thereby improving the cleaning efficiency of the ice layer by the scraper.

[0012] Further, the conveying mechanism includes two conveying rollers horizontally rotatably connected to both ends of the frame, the conveyor belt is jointly sleeved on the peripheries of the two conveying rollers, and a motor is installed at one end of the frame, and the motor shaft of the motor is drivingly connected to one of the conveying rollers.

[0013] Through the above technical solution, when the motor is started, it will drive one of the conveying rollers to rotate. Through the driving of the conveyor belt by the conveying roller, the conveyor belt will drive the other conveying roller to rotate, so that the motor can drive the conveyor belt to move to convey the frozen food raw materials.

[0014] Further, a plurality of tensioning rollers are provided on the frame, and the peripheries of the tensioning rollers are in rolling contact with the surface of the conveyor belt.

[0015] Through the above technical solution, the conveyor belt is tensioned by the tensioning rollers to prevent the conveyor belt from becoming slack.

[0016] Further, a limit nut is fixedly sleeved on one end of the sliding column away from the scraper, and a first spring is wound around the periphery of the sliding column, and two ends of the first spring in the direction of the elastic force are respectively elastically abutted against the limit nut and the support.

[0017] Through the above technical solution, the first spring elastically abuts against the limit nut, so that when the scraping plate moves passively with the ice layer, the limit nut will continuously squeeze the first spring, thereby enabling the first spring to accumulate elastic potential energy. In this way, when the ice layer is scraped off by the scraping plate, the elastic potential energy accumulated by the first spring is released, which can drive the sliding column to move towards the discharging side of the conveyor belt, enabling the scraping plate to reset.

[0018] Furthermore, the ice knocking mechanism includes two ear blocks fixedly connected to the outer wall of the scraping plate. A lifting column is vertically slidably penetrated through the surface of the ear block. A ice knocking part is provided at the upper end of the lifting column. A reciprocating lifting driving unit is provided on the support. The reciprocating lifting driving unit is used to drive the lifting column to move vertically in a reciprocating manner.

[0019] Through the above technical solution, the reciprocating lifting driving unit drives the lifting column to move vertically in a reciprocating manner, so that the ice knocking part can generate a knocking force on the surface of the ice layer, and the surface of the ice layer is squeezed by the scraping plate and knocked by the ice knocking part, so that the ice layer can be broken.

[0020] Furthermore, the reciprocating lifting driving unit includes a fixing plate horizontally fixedly connected to the outer walls of the two supports. Two support columns are horizontally and fixedly penetrated through the outer wall of the fixing plate. A sliding seat is slidably sleeved on the support columns. The sliding seat is connected to the bottom of the scraping plate through a connecting arm. Two rotating parts are horizontally rotatably connected to the top of the sliding seat. The opposite end faces of two adjacent rotating parts are rotatably connected by a hinge rod through a pivot. The end of the hinge rod away from the rotating part is rotatably connected to the lower end of the lifting column.

[0021] Through the above technical solution, the rotating part drives the hinge rod to rotate, and the rotating part, the hinge rod and the lifting rod form a crank-slider mechanism. When the rotating part rotates, it can drive the lifting column to reciprocate vertically, so that the ice knocking part can generate a knocking force on the ice layer.

[0022] Furthermore, a rack section is provided on the top surface of the support column, and a gear section is provided on the periphery of the rotating part. The gear section meshes with the rack section.

[0023] Through the above technical solution, when the scraping plate moves passively with the ice layer on the conveyor belt, the scraping plate will drive the sliding seat to slide on the support column, and the gear section on the rotating part will mesh with the rack section on the support column, so that the rotating part drives the hinge rod to swing, enabling the hinge rod to reciprocally drive the lifting column to move vertically.

[0024] Further, the ice-breaking part includes a first ice-breaking block and a second ice-breaking block. The top thickness of the first ice-breaking block and the second ice-breaking block increases sequentially from top to bottom. One side surface of the first ice-breaking block is in sliding contact with the surface of the scraper. The upper end of the lifting column is fixedly connected to the bottom surface of the first ice-breaking block. The surface of the second ice-breaking block is in sliding contact with the surface of the first ice-breaking block. The second ice-breaking block is connected to the surface of the first ice-breaking block through a reset unit. The reset unit is arranged on the surface of the first ice-breaking block and imparts potential energy to the second ice-breaking block to move in a direction away from the first ice-breaking block. A separation unit is provided on the scraper. The separation unit is used to drive the first ice-breaking block and the second ice-breaking block to move in a direction away from each other.

[0025] Through the above technical solution, after the first ice-breaking block and the second ice-breaking block strike the ice layer and form a strike seam on the ice layer, they will continue to move upward, causing the separation unit to be triggered. Then, the separation unit drives the second ice-breaking block to move in a direction away from the first ice-breaking block, enabling the second ice-breaking block and the first ice-breaking block to expand the strike seam. After the strike seam is expanded, the ice layer can break apart.

[0026] Further, the reset unit includes a fixing rod horizontally and fixedly connected to the surface of the first ice-breaking block. A through hole for the fixing rod to freely pass through is opened on the outer wall of the second ice-breaking block. A limiting ring is fixedly sleeved at one end of the fixing rod passing through the second ice-breaking block. A second spring is wound around the periphery of the fixing rod. The two ends in the elastic force direction of the second spring elastically abut against the limiting ring and the second ice-breaking block respectively.

[0027] Through the above technical solution, the second spring generates an elastic abutting force on the second ice-breaking block, thereby imparting potential energy to the second ice-breaking block to move in a direction towards the first ice-breaking block.

[0028] Further, the separation unit includes a driving column horizontally and fixedly penetrating the outer wall of the scraper. An avoidance groove for the driving column to freely pass through is opened on the surface of the first ice-breaking block. A cavity for the end of the driving column to freely pass through is opened on the outer wall of the second ice-breaking block. A ball is rotatably installed at one end of the driving column penetrating into the cavity. An inclined surface is provided on the lower inner wall of the cavity. The inclined surface is used in cooperation with the ball.

[0029] Through the above technical solution, when the lifting column drives the first ice-breaking block and the second ice-breaking block to move upward to a fixed position, the ball will rollingly contact the upper side of the inclined surface. As the lifting column continues to move upward, the ball rolls on the inclined surface and can drive the second ice-breaking block to move in a direction away from the first ice-breaking block.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. In the present invention, the top of the scraper contacts the lower surface of the conveyor belt, enabling the ice layer on the surface of the conveyor belt to come into contact with the surface of the scraper. As the conveyor belt moves, the ice layer will be blocked by the scraper, causing the ice layer to separate from the surface of the conveyor belt. When the adhesion between the ice layer and the conveyor belt is relatively large and it is difficult for the ice layer to detach from the surface of the conveyor belt, the scraper will be squeezed by the ice layer, resulting in a movement in the direction of the feeding side of the conveyor belt, causing the sliding column to move horizontally on the support. At the same time, the ice-breaking mechanism is triggered to act, and the ice-breaking mechanism generates a repeated knocking force on the surface of the ice layer near the top of the scraper, causing the ice layer to break when subjected to the knocking force, and then enabling the scraper to scrape off the ice layer.

[0032] 2. In the present invention, since the scraper can passively generate a certain degree of horizontal movement through the sliding of the sliding column on the support, and during the horizontal movement, it can continuously squeeze the ice layer and give the knocking mechanism enough time to knock the ice layer near the top of the scraper, thereby improving the cleaning efficiency of the ice layer by the scraper.

[0033] 3. In the present invention, after the first ice-knocking block and the second ice-knocking block knock the ice layer and form a knocking seam on the ice layer, they will continue to move upward, causing the separation unit to be triggered to act. Then, the separation unit drives the second ice-knocking block to move away from the first ice-knocking block, enabling the second ice-knocking block and the first ice-knocking block to widen the knocking seam. After the knocking seam is widened, the ice layer can break apart. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The working principle of the present invention:

[0053] When ice layers are generated on the surface of the conveyor belt 1, as the conveyor belt 1 runs, the ice layers will contact the top edge of the scraper 8. If the thickness of the ice layer is small, the scraper 8 can scrape off the ice layer within a short time of contacting the ice layer. And at this time, the elastic abutting force of the first spring 13 on the limit nut 12 is greater than the acting force required for the ice layer to fall off from the surface of the conveyor belt 1, that is, at this time, the compression degree of the first spring 13 is small;

[0054] When the ice layer is thick, the scraper 8 will move passively with the ice layer. During the movement, the sliding column 14 will move with the scraper 8 towards the feeding side direction of the conveyor belt 1, and the limit nut 12 will compress the first spring 13, thereby enabling the first spring 13 to accumulate elastic potential energy;

[0055] When the sliding column 14 is moving, the gear section on the rotating part 25 will mesh and drive on the rack section of the support column 17, thereby enabling the rotating part 25 to drive the hinge rod 30 to swing, enabling the hinge rod 30 to drive the lifting column 23 to move vertically up and down reciprocally, and further enabling the first ice breaker 9 and the second ice breaker 6 to move upwards together. The pointed parts of the upper sections of the first ice breaker 9 and the second ice breaker 6 move upwards and generate a cutting force on the ice layer. During this process, the first ice breaker 8 and the second ice breaker 6 do not move away from each other;

[0056] When the first ice knocking block 9 and the second ice knocking block 6 move upward to the fixed position (at this time, the first ice knocking block 9 and the second ice knocking block 6 do not touch the belt body of the conveyor belt 1), the ball 28 will roll in the cavity 29 and gradually roll to the upper end of the inclined surface 27, and then move upward with the first ice knocking block 9, so that the ball 28 rolls on the inclined surface 27, thereby driving the second ice knocking block 6 to move away from the scraper 8, so that the first ice knocking block 9 and the second ice knocking block 6 can expand the cutting seam of the ice layer, so that the ice layer can be broken.
