Description

Technical Field

[0001] The present invention belongs to the field of cold chain transportation of frozen products, and in particular relates to a frozen product separation and transportation device and a use method thereof. Background Art

[0002] In the field of frozen food cold chain transportation, the frozen food separation and transportation device plays a key role. Its main function is to separate frozen products that are frozen together without melting, and to achieve efficient transportation with the help of conveyor rollers, creating convenient conditions for subsequent workers to sort and pack, greatly improving the efficiency and orderliness of the frozen food processing process.

[0003] The existing frozen product separation and transportation device includes a conveyor roller, on which the frozen products to be processed are placed, and the conveyor roller drives the frozen products to move forward along a set track. A separation mechanism is installed directly above the conveyor roller, and the separation mechanism includes a telescopic cylinder, which can control the telescopic movement of the piston rod in the vertical direction. An ice-breaking hammer is installed at the end of the piston rod. When the device starts running, the telescopic cylinder periodically drives the piston rod to extend and retract up and down according to a pre-set program. This reciprocating motion of the piston rod drives the ice-breaking hammer to hit the frozen products frozen together on the conveyor roller at a constant frequency and force. Under the continuous hitting action, the adhesion between the frozen products is gradually destroyed, and separation is achieved. The separated frozen products continue to move forward with the conveyor roller and arrive at the designated sorting area, which is convenient for the staff to carry out subsequent sorting and packaging operations.

[0004] However, in actual production applications, frozen products are stacked in various ways during frozen storage, and the freezing conditions of different cold storages are different, resulting in extremely irregular shapes and different heights of frozen products. When the icebreaker hammer performs the striking task, once the height of the frozen product is significantly lower than the normal range, even if the icebreaker hammer goes down at full speed according to the preset stroke, it cannot touch the frozen product. This part of the frozen product cannot be separated during the operation of the device and can only be handled manually. When faced with frozen products that are too high, the icebreaker hammer will contact the frozen product in advance and be blocked before completing the preset stroke. This causes the piston rod of the telescopic cylinder to bear pressure far beyond the design limit, and overload conditions frequently occur. In the long run, it is very easy to cause the piston rod to bend and deform, greatly shortening its service life and increasing the cost of equipment maintenance and replacement. Summary of the invention

[0005] In view of the problem that the stroke of the existing ice-breaking hammer is fixed and cannot be flexibly adjusted according to the height of the frozen product, the present invention provides a frozen product separation and transportation device with a variable ice-breaking hammer stroke that can be flexibly adjusted according to the height of the frozen product and a use method thereof.

[0006] On the first aspect, in order to solve the above problems, the technical solution adopted by the present invention is: a frozen product separation and transportation device, including a conveyor, a workbench is provided at the output port of the conveyor, the workbench is inclined, the input port height of the workbench is higher than the output port height, pallets are fixed on both sides of the workbench, a rocker is provided above the pallet, the middle part of the rocker is hinged to the pallet, the front end of the rocker is located above the workbench and is fixed with an ice-breaking hammer, an ice-breaking drive mechanism is provided on the pallet, and the ice-breaking drive mechanism can periodically press the rear end of the rocker back and forth; a box is provided at the output port of the workbench, a vibrating screen mechanism is provided in the box, the vibrating screen mechanism can separate the crushed ice that falls off the frozen product from the frozen product, and a collection frame is provided below the vibrating screen mechanism.

[0007] In this technical solution, the conveyor is responsible for transporting the frozen products to be separated to the workbench. The ice-breaking drive mechanism on the pallet operates by periodically pressing the rear end of the rocker back and forth, so that the rocker rotates in a circle around the hinge point between the middle part and the pallet, thereby showing a periodic swing. During this period, the ice-breaking hammer installed at the front end of the rocker will synchronously perform periodic lifting and lowering actions, and can hit the frozen products to be separated placed on the workbench until the frozen products are successfully separated. The separated frozen products and the fallen crushed ice will slide from the workbench into the box. The vibrating screen mechanism in the box vibrates to sieve the crushed ice into the collection frame below, while the separated frozen products remain on the vibrating screen mechanism, waiting for subsequent processing. In summary, in this solution, the ice-breaking drive mechanism is only responsible for lifting the ice-breaking hammer to a predetermined height, and the falling distance of the ice-breaking hammer depends entirely on the distance between the predetermined height and the frozen products. Therefore, the stroke of the ice-breaking hammer in this solution is variable and can be flexibly adjusted according to the height of the frozen product, thereby effectively avoiding the situation where the frozen product cannot be hit or is overloaded.

[0008] Furthermore, a pressure plate is fixed to the rear end of the rocker, and a buffer spring is arranged below the pressure plate, the upper end of the buffer spring is fixedly connected to the bottom of the pressure plate, and the lower end of the buffer spring is fixedly connected to the upper surface of the support plate. The buffer spring can ensure that the movement of the rear end of the rocker is smoother. During the pressing process of the ice-breaking drive mechanism, the buffer spring can adaptively adjust the elastic force according to the force conditions, so that the movement of the pressure plate and the rear end of the rocker will not be too abrupt, which helps to maintain the continuity and stability of the ice-breaking hammer hitting the frozen products and ensure the consistency of the hitting effect. In addition, the buffer spring can also play a certain role in limiting and resetting the swing of the rocker. When the ice-breaking drive mechanism stops pressing, the elastic restoring force of the buffer spring will push the pressure plate and the rear end of the rocker to reset, prepare for the next pressing and swinging, and limit the excessive swing of the rear end of the rocker, ensuring the safety and reliability of the operation of the entire mechanism.

[0009] Furthermore, the ice-breaking drive mechanism includes a first drive motor, which is fixed to the upper surface of the support plate, and a connecting wheel is fixed to the output end of the first drive motor, and a lever is fixed to the connecting wheel. The lever is located above the pressure plate, and the lever can press the top of the pressure plate, and the lever can be separated from the pressure plate as the connecting wheel rotates. As a power source, the first drive motor can accurately control the rotation speed, and then accurately adjust the rotation speed of the connecting wheel, so that the pressing frequency of the lever on the pressure plate is stable and adjustable. By changing the rotation speed of the first drive motor, the striking frequency of the ice-breaking hammer can be flexibly adjusted according to the difficulty and requirements of separating different frozen products to achieve the best separation effect.

[0010] Furthermore, there are two levers, both of which are fixed on the outer circumference of the connecting wheel, and the two levers are symmetrically distributed with the axis of the connecting wheel as the base point. The two levers press the pressure plate alternately, and compared with a single lever, at the same connecting wheel speed, the frequency of pressing the pressure plate can be doubled, thereby increasing the striking frequency of the ice-breaking hammer. A higher striking frequency helps to strike the frozen products to be separated more quickly, improving the efficiency of ice breaking and separation.

[0011] Furthermore, sliders are fixed on both sides of the pressing plate, and support plates are provided on both sides of the pressing plate. The bottom of the support plate is fixedly connected to the upper surface of the support plate, and a slide groove is provided on the support plate. The slide groove is arc-shaped, and the center of the arc is the hinge between the middle of the rocker and the support plate. The radius of the arc is equal to the distance between the middle hinge of the rocker and the slider, and the sliders on both sides of the pressing plate are respectively clamped in the slide grooves of the corresponding side support plates. The arc design of the slide groove and the relationship between its center and the middle hinge of the rocker can accurately limit the movement trajectory of the pressing plate. The pressing plate can only move along the arc path with the middle hinge of the rocker as the center and the distance between the middle hinge of the rocker and the slider as the radius. This ensures the stability and accuracy of the pressing plate during the movement, and then ensures the accuracy of the movement of the ice-breaking hammer, so that it can accurately hit the frozen product to be separated, and improve the ice-breaking effect. The sliders on both sides of the pressing plate are clamped with the slide grooves on the support plate to form a stable sliding connection structure. This structure can not only withstand the force generated by the pressing of the ice-breaking drive mechanism, but also provide lateral support for the pressure plate during the swing of the rocker arm to prevent the pressure plate from shaking or shifting, thereby enhancing the stability of the entire device and helping to extend the service life of the device.

[0012] Furthermore, the vibrating screen mechanism includes a vibrating frame, a feeding hole is provided at the bottom of the vibrating frame, a top block is fixed on the outer wall of the vibrating frame close to the workbench, and the top block can pass through the side wall of the box close to the workbench, a vibrating assembly is provided between the side of the vibrating frame and the box, the vibrating assembly can shake the vibrating frame, and a sliding assembly is provided between the bottom surface of the vibrating frame and the box, and the sliding assembly can make the vibrating frame slide smoothly in the box. The vibrating assembly causes the vibrating frame to shake, so that the separated frozen products and crushed ice can be fully mixed and moved in the vibrating frame, which makes it easier for the crushed ice to pass through the feeding hole and fall into the collection frame below, while the frozen products remain on the vibrating screen, thereby achieving an efficient screening effect and improving the separation efficiency. The vibration method can effectively prevent the crushed ice and frozen products from blocking the feeding hole or accumulating in the vibrating frame during the screening process, ensuring the smooth progress of the screening process, reducing the frequency of manual cleaning, and improving work efficiency. The sliding assembly enables the vibration frame to slide smoothly in the box, provides stable support and guidance for the vibration frame, ensures the stability of the vibration frame during vibration, avoids structural damage or displacement caused by vibration, and extends the service life of the equipment.

[0013] Furthermore, the vibration assembly includes a second drive motor, which is fixed on the outer side wall of the box body near the workbench, and a cam is fixed on the output shaft of the second drive motor, and the position of the cam corresponds to the top block; the vibration assembly also includes a buffer plate, which is fixed on the inner side wall of the box body near the workbench, and a connecting spring is arranged between the buffer plate and the vibration frame, one end of the connecting spring is fixedly connected to the buffer plate, and the other end of the connecting spring is fixedly connected to the vibration frame. The cam is driven to rotate by the second drive motor, and the eccentric structure of the cam can be used to convert the rotational motion of the second drive motor into the reciprocating vibration of the vibration frame. Every time the cam rotates one circle, it will produce a push and release action on the top block, so that the vibration frame will vibrate once. This method can efficiently generate stable vibration and ensure the screening effect of the vibrating screen. The setting of the buffer plate and the connecting spring plays a role of buffering and protection. When the cam pushes the top block to make the vibration frame vibrate, the connecting spring will be elastically deformed, absorb part of the vibration energy, avoid rigid collision between the vibration frame and the box body, reduce the wear and noise of the equipment, and also protect the structure of the vibration frame and the box body from damage, thereby extending the service life of the equipment. By adjusting the speed of the second drive motor to change the rotation speed of the cam, the vibration frequency and intensity of the vibration frame can be adjusted. According to different frozen product separation requirements and screening effects, the vibration parameters can be flexibly adjusted to achieve the best screening efficiency and quality.

[0014] Furthermore, the sliding assembly includes a retaining frame, which is fixedly connected to the bottom surface of the vibration frame, and a ball is installed in the retaining frame, and the bottom of the ball is in contact with the inner bottom of the box. The ball rolls in the retaining frame and contacts the inner bottom of the box, converting the sliding friction between the vibration frame and the box into rolling friction. The friction coefficient of rolling friction is much smaller than that of sliding friction, which can effectively reduce the resistance of the vibration frame during the sliding process, making it easier for the vibration frame to slide in the box, reducing energy loss, and also reducing the wear of components.

[0015] Furthermore, a guide plate is provided at the output port of the vibration frame, which can accurately guide the frozen products after vibration screening to a designated position, thereby preventing the frozen products from being scattered around during output, and ensuring the accuracy and orderliness of the frozen product transmission.

[0016] In a second aspect, the present invention further provides a method for using a frozen product separation and transportation device, which is applied to the frozen product separation and transportation device and comprises the following steps: Step one: Place the frozen products to be separated on the conveyor, which transports the frozen products to be separated to the workbench. The staff only needs to place the frozen products to be separated at the input port of the conveyor, without having to approach the subsequent dangerous links such as ice breaking and screening. In addition, the conveyor greatly shortens the time of manual handling and improves the transportation efficiency of the frozen products to be separated.

[0017] Step 2: Start the ice-breaking drive mechanism. Its output end will periodically press the rear end of the rocker back and forth at a set frequency. The rocker rotates in a circle around the hinge point between the middle part and the support plate, showing a periodic swinging state. During this process, the ice-breaking hammer installed at the front end of the rocker also performs periodic lifting and lowering actions synchronously, and hits the frozen products to be separated on the workbench until they are successfully separated. The working mode of the ice-breaking drive mechanism is to only lift the ice-breaking hammer to a predetermined height, and the falling distance is determined by the actual distance between the predetermined height and the frozen products. This gives the ice-breaking hammer a variable stroke height. The ice-breaking hammer can flexibly adjust the falling stroke according to the specific height of the frozen products, realizing adaptive adjustment of the ice-breaking hammer stroke.

[0018] Step 3: After being beaten and separated, the frozen products and the crushed ice slide from the workbench into the box. The vibrating screen mechanism in the box vibrates to sieve the crushed ice into the collection frame below, while the separated frozen products remain on the vibrating screen mechanism, waiting for subsequent processing. The crushed ice and the separated frozen products automatically slide into the box and are separated by the vibrating screen mechanism. There is no need for excessive manual intervention throughout the process. The staff only needs to clean the collection frame and deal with the frozen products left on the vibrating screen, which greatly reduces the manpower input and makes the separation work more convenient and efficient.

[0019] It can be seen from the above technical scheme that the advantages of the present invention are: in this technical scheme, the first drive motor drives the connecting wheel to rotate, thereby driving the lever to rotate synchronously, and the lever periodically presses the pressure plate back and forth, so that the rocker rotates in a circle around the hinge point between the middle part and the support plate, thereby presenting a periodic swing. At the same time, the ice-breaking hammer installed at the front end of the rocker will synchronously perform periodic lifting and lowering actions, and can hit the frozen products to be separated placed on the workbench until the frozen products are successfully separated. The separated frozen products and the broken ice will slide from the workbench into the box. The vibration frame in the box vibrates to drop the broken ice sieve into the collection frame below, while the separated frozen products remain on the vibration frame and are transferred to the designated position through the guide plate. In summary, in this scheme, the lever and the rocker constitute a crank rocker mechanism similar to that of the crank rocker, which can periodically lift the ice-breaking hammer to a predetermined height, and the falling distance of the ice-breaking hammer depends entirely on the distance between the predetermined height and the frozen product. Therefore, the ice-breaking hammer in this scheme is rigidly connected to the frozen product during the process of hitting the frozen product, which can ensure the separation of the frozen product. At the same time, the stroke of the ice-breaking hammer is variable and can be flexibly adjusted according to the height of the frozen product, thereby effectively avoiding the situation where the frozen product cannot be hit or is overloaded.

DETAILED DESCRIPTION

[0023] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0024] Embodiment 1: A frozen product separation and transportation device, such as Figure 1 As shown, it includes a conveyor 1, a workbench 2 and a box 18. The output port of the conveyor 1 is connected to the input port of the workbench 2, and the height of the output port of the conveyor 1 is higher than the height of the input port of the workbench 2. The setting of the height difference allows the frozen products to be separated to be more smoothly transferred from the output port of the conveyor 1 to the input port of the workbench 2 with the assistance of gravity. The output port of the workbench 2 is connected to the input port of the box 18. Similarly, the height of the output port of the workbench 2 is higher than the height of the input port of the box 18, which facilitates the accurate entry of the separated frozen products and crushed ice into the box 18. The conveyor 1 can transport the frozen products to be separated to the workbench 2, and the workbench 2 is provided with an ice-breaking hammer 16 that can periodically reciprocate from a predetermined height. The ice-breaking hammer 16 can smash the frozen products to be separated, which is convenient for subsequent sorting and packaging. The separated frozen products and crushed ice will slide from the workbench 2 into the box 18. A vibrating screen mechanism is provided in the box 18, and a collecting frame 29 is provided below the vibrating screen mechanism. The vibrating screen mechanism can retain the separated frozen products and screen the crushed ice and drop it into the collecting frame 29.

[0025] In this specific embodiment, the conveyor 1 is an existing device, such as the conveyor 1 produced by Shanghai Shenang Conveying Equipment Co., Ltd. and Shanghai Xiayun Conveying Machinery Equipment Co., Ltd., both of which can be applied to this embodiment.

[0026] like Figure 2 As shown, in this specific embodiment, the workbench 2 specifically adopts the following structure: the workbench 2 is a flat plate structure as a whole, and is tilted, and its tilting trend is gradually reduced from the end close to the input port of the conveyor 1 to the end close to the output port of the box 18. The upper surface of the workbench 2 is fixed with an anti-slip strip 4 by bonding. The function of the anti-slip strip 4 is to prevent the frozen products to be separated from sliding directly from the workbench 2 into the box 18 without being fully processed. A bracket is welded at the bottom of the workbench 2, which can provide necessary support for the workbench 2 and ensure the stability of the workbench 2 during the loading of frozen products and related operations.

[0027] like Figure 3 As shown, baffles 3 are provided on both sides of the workbench 2. The baffle 3 is composed of a vertical portion and an inclined portion which are integrally processed, and the vertical portion is located below the inclined portion. The vertical portion is fixedly connected to the side of the workbench 2 by welding, thereby ensuring that the baffle 3 can be firmly installed on both sides of the workbench 2. The inclined direction of the inclined portion is away from the workbench 2. A buffer strip 17 is fixed to the inclined portion by bonding, and the length direction of the buffer strip 17 is consistent with the transportation direction of the frozen product to be separated. A support plate 5 is also welded to the inclined portion, and the support plate 5 is horizontally arranged to provide a stable platform for the subsequent installation of related components.

[0028] A connecting seat 15 is provided on the upper surface of the two support plates 5. The connecting seat 15 includes two vertical plates parallel to each other, and the bottoms of the two vertical plates are connected to the upper surface of the support plate 5 by welding. A hinge shaft is provided between the two vertical plates, and the two ends of the hinge shaft are fixedly connected to the vertical plates on both sides by bolts. A rocker 14 is installed on the connecting seat 15, and the cross section of the rocker 14 is rectangular. A light hole penetrating the rocker 14 is provided on the side of the middle part of the rocker 14, and the hinge shaft of the connecting seat 15 just penetrates the light hole of the rocker 14. A bearing is installed between the hinge shaft and the light hole, and the inner ring of the bearing and the hinge shaft adopt an interference fit, and the outer ring of the bearing and the light hole also adopt an interference fit. This assembly method allows the rocker 14 to rotate flexibly around the hinge shaft of the connecting seat 15.

[0029] The front end of the rocker 14 is located above the workbench 2, and the front end of the rocker 14 is fixed with an icebreaker hammer 16 by bolt connection. The icebreaker hammer 16 is rectangular in shape and made of rubber. The rear end of the rocker 14 is connected to the pressure plate 12 by welding, and the pressure plate 12 is a rectangular flat plate. Figure 4 As shown, a buffer spring 13 is provided below the pressure plate 12, the upper end of the buffer spring 13 is fixed to the bottom of the pressure plate 12 by welding, and the lower end of the buffer spring 13 is fixedly connected to the upper surface of the support plate 5 by welding as well.

[0030] Slide blocks 11 are welded on both sides of the pressure plate 12, and the sliders 11 are cylindrical in shape as a whole. At the same time, support plates 9 are arranged on both sides of the pressure plate 12. The bottoms of the two support plates 9 are welded to the upper surface of the support plate 5, and the two support plates 9 are parallel to each other. A slide groove 10 is arranged on the support plate 9, and the slide groove 10 is arc-shaped. The center of the arc is the hinge between the middle part of the rocker 14 and the support plate 5, and the radius of the arc is equal to the distance between the middle hinge of the rocker 14 and the slide block 11. The slide blocks 11 on both sides of the pressure plate 12 are respectively clamped in the slide grooves 10 of the corresponding side support plates 9. When the rocker 14 rotates around the hinge axis of the connecting seat 15, the slide block 11 can slide in the slide groove 10, and at the same time limit the rocker 14, effectively limiting the swing angle of the rocker 14.

[0031] Ice-breaking drive mechanisms are provided on the two support plates 5 on both sides of the workbench 2. The ice-breaking drive mechanism includes a first drive motor 6, which is fixed to the upper surface of the support plate 5 by bolts. A connecting wheel 7 is fixed to the output end of the first drive motor 6 by bolts, and the axis of the connecting wheel 7 coincides with the axis of the output end of the first drive motor 6. A lever 8 is welded on the outer circumferential surface of the connecting wheel 7, and the lever 8 is located above the pressure plate 12. As the connecting wheel 7 rotates, the lever 8 can press the top of the pressure plate 12. When the lever 8 presses the pressure plate 12, the pressure plate 12 begins to compress the buffer spring 13, and at the same time, the ice-breaking hammer 16 at the front end of the rocker 14 is lifted. As the connecting wheel 7 continues to rotate, when the lever 8 is separated from the pressure plate 12, the ice-breaking hammer 16 reaches the predetermined position at this time. At this time, the pressure plate 12 loses the pressure of the lever 8, and the ice-breaking hammer 16 begins to fall under the action of gravity, and the pressure plate 12 also returns to the initial position. In this embodiment, there are two levers 8 , both of which are welded to the outer circumferential surface of the connecting wheel 7 , and the two levers 8 are centrally symmetrically distributed with the axis of the connecting wheel 7 as a base point.

[0032] like Figure 7 As shown, in this specific embodiment, the box body 18 includes a bottom plate. A notch is provided in the middle position of the bottom plate, and the three sides of the upper surface of the bottom plate close to the workbench 2 are respectively connected to three mutually perpendicular side plates by welding. That is, there is no side plate on the side of the bottom plate away from the workbench 2, and an opening is provided here. In addition, a rectangular opening is provided on the side plate of the box body 18 close to the workbench 2. A support frame 28 is provided at the lower part of the box body 18, and the top of the support frame 28 is fixedly connected to the box body 18 by bolts, and the support frame 28 can support the box body 18. A collection frame 29 is installed inside the support frame 28, and the collection frame 29 is connected to the box body 18 through the notch.

[0033] In this specific embodiment, the vibrating screen mechanism includes a vibrating frame 22. The output port of the vibrating frame 22 away from the workbench 2 is connected to the guide plate 30 by welding. A plurality of feed holes 23 are provided at the bottom of the vibrating frame 22, and all the feed holes 23 are connected to the collecting frame 29. A top block 21 is welded on the outer wall of the vibrating frame 22 close to the workbench 2, and the top block 21 can pass through the rectangular opening on the side plate of the box 18 close to the workbench 2. A vibrating assembly is provided between the side of the vibrating frame 22 and the box 18, and the vibrating assembly can cause the vibrating frame 22 to shake. A sliding assembly is provided between the bottom surface of the vibrating frame 22 and the box 18, and the sliding assembly can ensure that the vibrating frame 22 slides smoothly in the box 18.

[0034] like Figure 5 As shown, the vibration assembly includes a second drive motor 19, which is fixed to the outer wall of the side plate of the box 18 near the workbench 2 by bolts. A cam 20 is fixed to the output shaft of the second drive motor 19 by bolts, and the position of the cam 20 corresponds to the top block 21. When the cam 20 rotates, the cam 20 can push the top block 21 and then push the vibration frame 22. Figure 6 As shown, the vibration assembly also includes a buffer plate 25, which is welded and fixed on the inner wall of the side plate of the box body 18 close to the workbench 2. There are two buffer plates 25, and the two buffer plates 25 are distributed on both sides of the top block 21. A connecting spring 24 is provided between the two buffer plates 25 and the vibration frame 22, one end of the connecting spring 24 is fixedly connected to the buffer plate 25 by welding, and the other end of the connecting spring 24 is also fixedly connected to the vibration frame 22 by welding.

[0035] like Figure 8 , 9 As shown, the sliding assembly includes a retaining frame 26, and the retaining frame 26 is connected to the bottom surface of the vibration frame 22 by welding. Ball bearings 27 are installed in the retaining frame 26, and the bottoms of these ball bearings 27 are tightly abutted against the inner bottom of the box body 18, that is, the bottom plate of the box body 18, so as to ensure that the vibration frame 22 can slide smoothly and stably in the box body 18.

[0036] Embodiment 2: Based on the frozen product separation and transportation device provided in Embodiment 1, this embodiment further provides a method for using the frozen product separation and transportation device, comprising the following steps: Step 1: Loading and positioning of frozen products. Place the frozen products to be separated on conveyor 1. Driven by the conveyor rollers of conveyor 1, the frozen products are transported forward and transported out of the output port of conveyor 1, and fall on the input port of workbench 2. Since workbench 2 is inclined, the frozen products will move from the input port to the output port of workbench 2 along the inclined direction under the action of gravity. At the same time, the anti-slip strips 4 bonded to workbench 2 increase the friction between the frozen products and the table surface, so that the frozen products can only move slowly, thereby buying enough time for the separation of the frozen products.

[0037] Step 2: Ice breaking and separation of frozen products. Start the ice breaking drive mechanism, the output shaft of the first drive motor 6 drives the connecting wheel 7 to rotate, and the connecting wheel 7 drives the two levers 8 to rotate synchronously. When the first lever 8 contacts and presses the pressure plate 12, the pressure plate 12 presses the buffer spring 13 downward, and the sliders 11 on both sides of the pressure plate 12 also slide downward in the slide groove 10. At this time, the rocker 14 swings in a circle with the hinge point between the middle part and the support plate 5 as the axis, the height of the pressure plate 12 decreases, and the height of the ice breaking hammer 16 increases. As the connecting wheel 7 continues to rotate, the first lever 8 separates from the pressure plate 12, the pressure plate 12 drops to the lowest position, and the ice breaking hammer 16 rises to the highest position. Thereafter, the buffer spring 13 releases the pressure to push the pressure plate 12 up, the slider 11 slides upward in the slide groove 10, and the ice breaking hammer 16 begins to fall due to gravity, and strikes the frozen product to be separated forcefully until the frozen product is successfully separated. Then, the second lever 8 repeats the above action and continues to control the ice breaking hammer 16 to strike the frozen product. It is worth noting that the ice-breaking hammers 16 on the supporting plates 5 on both sides of the workbench 2 are staggered along the moving direction of the frozen products, which can perform a second blow on the frozen products and effectively ensure that the frozen products are completely separated.

[0038] Step three: screening and collection of frozen products. After being struck and separated, the frozen products and the detached broken ice slowly slide into the box body 18 under the dual effects of the striking vibration of the ice-breaking hammer 16 and the tilting structure of the workbench 2. At this time, the vibration component is turned on, and the output shaft of the second drive motor 19 drives the cam 20 to rotate, and the raised part of the cam 20 periodically pushes the top block 21, thereby driving the vibration frame 22 to move. When the raised part of the cam 20 pushes the top block 21, the connecting spring 24 between the vibration frame 22 and the buffer plate 25 is stretched; the cam 20 continues to rotate, and after the raised part of the cam 20 leaves the top block 21, the connecting spring 24 rebounds and pulls the vibration frame 22 back to the initial position; as the cam 20 continues to rotate, the raised part of the cam 20 pushes the top block 21 again, and the vibration frame 22 starts to move again, thereby achieving continuous shaking of the vibration frame 22.

[0039] During the shaking process of the vibration frame 22, the holder 26 on the bottom of the vibration frame 22 shakes synchronously, and the balls 27 in the holder 26 roll at the contact point with the bottom of the box 18, ensuring the smooth shaking of the vibration frame 22. At the same time, the separated frozen products and the fallen crushed ice are transported to the designated location through the guide plate 30 at the outlet of the vibration frame 22 for subsequent processing under the shaking of the vibration frame 22, and the fallen crushed ice falls from the discharge hole 23 at the bottom of the vibration frame 22 to the collection frame 29 below.

[0040] It can be seen from the above embodiments that the beneficial effect of the present invention is that, in the present technical solution, the first driving motor drives the connecting wheel to rotate, thereby driving the lever to rotate synchronously, and the lever periodically presses the pressure plate back and forth, so that the rocker rotates in a circle around the hinge point between the middle part and the support plate, thereby presenting a periodic swing. At the same time, the ice-breaking hammer installed at the front end of the rocker will synchronously perform periodic lifting and lowering actions, and can hit the frozen products to be separated placed on the workbench until the frozen products are successfully separated. The separated frozen products and the broken ice will slide from the workbench into the box. The vibration frame in the box vibrates to drop the broken ice sieve into the collection frame below, while the separated frozen products remain on the vibration frame and are transferred to the designated position through the guide plate. In summary, in the present solution, the lever and the rocker constitute a crank rocker mechanism similar to the crank rocker mechanism, which can periodically lift the ice-breaking hammer to a predetermined height, and the falling distance of the ice-breaking hammer depends entirely on the distance between the predetermined height and the frozen product. Therefore, the ice-breaking hammer in this scheme is rigidly connected to the frozen product during the process of hitting the frozen product, which can ensure the separation of the frozen product. At the same time, the stroke of the ice-breaking hammer is variable and can be flexibly adjusted according to the height of the frozen product, thereby effectively avoiding the situation where the frozen product cannot be hit or is overloaded.
