Description
Technical Field
[0001] This utility model belongs to the field of bone sawing machine technology, specifically, it relates to an anti-splash bone sawing machine for frozen meat processing. Background Technology
[0002] In the field of frozen meat processing, bone saws are key pieces of equipment, mainly used to cut large pieces of frozen meat into specific sizes that meet processing requirements. Their performance directly affects processing efficiency, product precision, and operational safety.
[0003] In the traditional manual cutting of frozen meat, the operator must hold the frozen meat directly close to the high-speed rotating saw blade for feeding. This inevitably involves close contact with the saw blade. The high-speed rotating saw blade is sharp and spins at a fast speed. When operating manually, if the surface of the frozen meat is smooth and causes slippage, or if the operator is fatigued and makes operational errors, or if the operator is not focused, it is very easy for the hand or other parts of the limbs to accidentally come into contact with the saw blade, causing mechanical injuries such as cuts and scratches. In addition, the frozen meat itself is relatively hard, and the instantaneous reaction force may be generated when cutting, causing the operator to lose their grip, further increasing the risk of close contact between the limbs and the saw blade.
[0004] In view of the above problems, a splash-proof bone saw for frozen meat processing is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a splash-proof bone saw for frozen meat processing that can overcome or at least partially solve the above problems.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A splash-proof bone saw for processing frozen meat includes a base and a guide rail fixedly mounted on the base. A cutting assembly is provided on the base. The machine also includes a mounting plate that slides on the guide rail and a shielding assembly. A pushing assembly and an adjusting assembly are provided on the mounting plate. The pushing assembly and the adjusting assembly are respectively located on both sides of the cutting assembly and on the inside of the shielding assembly. After the pushing assembly and the adjusting assembly clamp the frozen meat, the mounting plate moves back and forth, causing the frozen meat to pass through the cutting assembly and be cut.
[0008] In a preferred embodiment of the present invention, the shielding assembly includes a mounting cover fixedly mounted on the mounting plate, a flip cover rotatably mounted on the mounting cover, a drive shaft slidably mounted on the flip cover, the drive shaft being rotatably connected to the mounting cover, and a second motor fixedly mounted on the side wall of the mounting cover, the output end of the second motor being fixedly connected to the drive shaft via a coupling.
[0009] In a preferred embodiment of this utility model: the cutting assembly includes a spindle box fixedly mounted on the base, with a first rotating shaft and a second rotating shaft rotatably mounted at the upper and lower ends of the spindle box, respectively. The first rotating shaft and the second rotating shaft are connected by a synchronous belt pulley group. Saw wheels are fixedly mounted on both the first rotating shaft and the second rotating shaft, and saw blades connected end to end are mounted on the two saw wheels. A first motor is fixedly mounted on the spindle box, and the output end of the first motor is fixedly connected to the second rotating shaft.
[0010] In a preferred embodiment of this utility model: the mounting plate and the base are provided with a discharge hole that communicates with each other, the base is provided with a discharge hopper, the discharge hopper is located below the discharge hole, wherein the discharge hopper is located in the hole formed by the closed loop of the saw blade, and the saw blade passes through the discharge hole.
[0011] In a preferred embodiment of this utility model: the pushing assembly includes a fourth motor fixedly mounted on the mounting cover, the output shaft of the fourth motor extending into the mounting cover and fixedly mounted with a second transmission screw, a first guide slide rod fixedly mounted on the mounting plate, a pushing plate slidably mounted on the first guide slide rod, the pushing plate being threadedly connected to the second transmission screw, and a positioning plate fixedly mounted on the mounting plate, the positioning plate being perpendicular to the pushing plate at 90°.
[0012] In a preferred embodiment of this utility model: the adjustment assembly includes a fifth motor fixedly mounted on the mounting cover, the output shaft of the fifth motor extending into the mounting cover and fixedly mounted with a third transmission screw, a second guide slide rod fixedly mounted on the mounting plate, an adjustment plate slidably mounted on the second guide slide rod, and the adjustment plate being threadedly connected to the third transmission screw.
[0013] In a preferred embodiment of this utility model: a first transmission screw is rotatably mounted on the bottom of the base, a third motor is fixedly mounted on the bottom of the base and its output end is fixedly connected to the first transmission screw, and a connecting block threadedly connected to the first transmission screw is fixedly mounted on the bottom of the mounting plate. In use, the third motor is started, and the third motor drives the first transmission screw to rotate. The first transmission screw drives the mounting plate to slide along the guide rail through the connecting block.
[0014] In a preferred embodiment of this utility model, a control host is fixedly installed on the base.
[0015] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0016] 1. This utility model uses a pusher component and an adjustment component to automatically clamp and fix the frozen meat in position. Then, a third motor drives the mounting plate to slide along the guide rail, so that the frozen meat actively passes through the saw blade to complete the cutting. The whole process does not require the operator to hold the frozen meat close to the saw blade. From the source of operation, it avoids the operator's limbs from close contact with the high-speed rotating saw blade, and eliminates the hidden dangers of slippage and unstable force during hand feeding that may cause the limbs to approach the saw blade.
[0017] 2. This utility model uses a pusher component and an adjustment component to automatically cut frozen meat, achieving precise control of the cutting thickness. Combined with a reciprocating feed mechanism driven by a third motor, it shortens the single cutting time and improves the cutting efficiency of large pieces of frozen meat.
[0018] 3. The transparent cover facilitates observation, the touch screen allows for intuitive parameter settings, and multiple preset parameters can be set for quick switching according to frozen meat processing needs; all contact parts are detachable for cleaning.
[0019] 4. This utility model uses a fully enclosed transparent mounting cover and a flip-top physical barrier design to control flying debris inside the equipment. Combined with an interlocking mechanism that automatically stops the machine when the flip-top is opened, it reduces the time that operators are exposed to dangerous areas, thereby preventing operators from being injured.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0034] Example: Refer to Figures 1-10 A frozen meat processing anti-splash bone saw includes a base 1 and a guide rail 11 fixedly installed on the base 1. The bottom of the base 1 is fixedly installed with a universal locking wheel 12 with a braking function, which facilitates the overall movement of the equipment and can lock the position by braking during operation to prevent the equipment from sliding and affecting the cutting accuracy.
[0035] Reference Figure 1 and Figure 2 A mounting plate 3 is slidably mounted on the guide rail 11, and a mounting cover 31 is fixedly mounted on the mounting plate 3. A flip cover 32 is rotatably mounted on the mounting cover 31. A pushing component and an adjusting component are provided inside the mounting cover 31, and the pushing component and the adjusting component are respectively located on both sides of the cutting component.
[0036] Reference Figure 2As shown in the figure, a drive shaft 34 is slidably mounted on the flip cover 32. The drive shaft 34 is rotatably connected to the mounting cover 31. A second motor 33 is fixedly mounted on the side wall of the mounting cover 31. The second motor 33 is a servo motor with a brake, which can precisely control the opening and closing angle of the flip cover 32. The flip cover 32 can be stably locked when it is stopped at any angle. The output end of the second motor 33 is fixedly connected to the drive shaft 34 through a coupling.
[0037] When in use, the second motor 33 drives the transmission shaft 34 to rotate, and the transmission shaft 34 drives the flip cover 32 to rotate to open or close, making it convenient for staff to add or replace frozen meat. When the flip cover 32 needs to be cleaned, the transmission shaft 34 can be removed through the quick-release coupling, the flip cover 32 can be removed as a whole, cleaned and reinstalled. If disassembly is not required, the flip cover 32 can also be rinsed directly when it is opened to the maximum angle.
[0038] Reference Figure 1 , Figure 2 , Figures 6-9 The cutting assembly includes a spindle box 2 fixedly mounted on a base 1. A first rotating shaft 21 and a second rotating shaft 22 are rotatably mounted on the upper and lower ends of the spindle box 2, respectively. The first rotating shaft 21 and the second rotating shaft 22 are connected by a synchronous belt pulley group 25. Saw wheels 23 are fixedly mounted on both the first rotating shaft 21 and the second rotating shaft 22. Saw blades 24 connected end to end are mounted on the two saw wheels 23. A first motor 26 is fixedly mounted on the spindle box 2. The output end of the first motor 26 is fixedly connected to the second rotating shaft 22.
[0039] Reference Figure 10 The saw blade 24 has serrations on both the front and rear edges to facilitate cutting frozen meat that moves back and forth with the mounting plate 3.
[0040] When in use, the first motor 26 is started, which drives the second rotating shaft 22 to rotate. The second rotating shaft 22 drives the first rotating shaft 21 to rotate through the synchronous belt pulley group 25. The first rotating shaft 21 and the second rotating shaft 22 synchronously drive the two saw wheels 23 to rotate, which in turn drives the saw blade 24 to rotate to cut the frozen meat.
[0041] Reference Figure 2 and Figure 3 The mounting plate 3 and the base 1 are provided with a discharge hole 7 that is connected. The base 1 is provided with a discharge hopper 71, which is located below the discharge hole 7. The discharge hopper 71 is located in the hole formed by the closed loop of the saw blade 24, and the saw blade 24 passes through the discharge hole 7.
[0042] When in use, the frozen meat cut off by the saw blade 24 falls into the discharge hopper 71 through the discharge hole 7, and then slides out through the inclined surface at the bottom of the discharge hopper 71.
[0043] Reference Figure 2 and Figure 7The feeding assembly includes a fourth motor 5 fixedly mounted on the mounting cover 31. The output shaft of the fourth motor 5 extends into the mounting cover 31 and is fixedly mounted with a second transmission screw 51. A first guide slide rod 52 is fixedly mounted on the mounting plate 3. A feeding plate 53 is slidably mounted on the first guide slide rod 52. The feeding plate 53 is threadedly connected to the second transmission screw 51. A positioning plate 54 is fixedly mounted on the mounting plate 3. The positioning plate 54 is perpendicular to the feeding plate 53 at 90°.
[0044] Reference Figure 3 A limit block 55 is provided on the mounting plate 3 near the discharge hole 7. When the push plate 53 comes into contact with the limit block 55, it stops moving forward to prevent the push plate 53 from colliding with the saw blade 24.
[0045] Reference Figure 2 and Figure 8 The adjustment assembly includes a fifth motor 6 fixedly mounted on the mounting cover 31. The output shaft of the fifth motor 6 extends into the mounting cover 31 and is fixedly mounted with a third transmission screw 61. A second guide slide rod 62 is fixedly mounted on the mounting plate 3. An adjustment plate 63 is slidably mounted on the second guide slide rod 62. The adjustment plate 63 is threadedly connected to the third transmission screw 61.
[0046] When the third transmission screw 61 drives the adjusting plate 63 to move towards the saw blade 24, there is a distance of 1-3 mm between it and the saw blade 24 after it moves to the limit position.
[0047] When the flip cover 32 is closed, the distance between the top of the adjusting plate 63 and the pusher plate 53 and the flip cover 32 is one millimeter to prevent meat scraps from splashing onto the second transmission screw 51 and the third transmission screw 61.
[0048] Reference Figure 5 The bottom of the base 1 is rotatably mounted with a first transmission screw 4. The bottom of the base 1 is fixedly mounted with a third motor 41 whose output end is fixedly connected to the first transmission screw 4. The bottom of the mounting plate 3 is fixedly mounted with a connecting block 42 that is threadedly connected to the first transmission screw 4. When in use, the third motor 41 is started, and the third motor 41 drives the first transmission screw 4 to rotate. The first transmission screw 4 drives the mounting plate 3 to slide along the guide rail 11 through the connecting block 42.
[0049] The adjusting component works in conjunction with the pushing component to cut the frozen meat. In use, the fifth motor 6 is started, driving the third transmission screw 61 to rotate. The third transmission screw 61 drives the adjusting plate 63 to slide along the second guide slide rod 62, moving it above the discharge hole 7. This controls the distance between the adjusting plate 63 and the saw blade 24 passing through the discharge hole 7, thus setting the cutting size for the frozen meat. The frozen meat is then placed on the mounting plate 3, causing it to contact the pushing plate 53 and the positioning plate 54. The pushing plate 53 then pushes the frozen meat towards the adjusting plate 63. The device moves so that the frozen meat comes into contact with the adjusting plate 63, and the pushing plate 53 and adjusting plate 63 clamp the frozen meat. Then the third motor 41 starts and drives the mounting plate 3 to move back and forth, so that the clamped frozen meat passes through the rotating saw blade 24, thereby cutting the frozen meat. After the first piece of frozen meat is cut off, the pushing plate 53 and adjusting plate 63 move 1-3 cm to the left and right sides of the mounting plate 3, so that the cut frozen meat falls into the discharge hole 7. Then the pushing plate 53 and adjusting plate 63 reset to clamp the frozen meat, and the mounting plate 3 moves again so that the frozen meat passes through the saw blade 24 to complete the cutting.
[0050] Reference Figure 1 The base 1 is fixedly installed with a control host 8. The control host 8 can set the rotation parameters of five motors, namely the initial distance between the control adjustment plate 63 and the saw blade 24, the rotation speed of the saw blade 24, the reciprocating speed of the mounting plate 3, the distance that the pusher plate 53 moves each time, and the speed at which the pusher plate 53 and the adjustment plate 63 move towards the two ends of the mounting plate 3 and reset. At the same time, the control host 8 can store cutting parameters inside, which is convenient for quickly switching parameters when cutting frozen meat.
[0051] Both the mounting cover 31 and the flip cover 32 are made of transparent material, which makes it easy to observe the internal cutting situation.
[0052] When the flip cover 32 is opened, the control host 8 automatically controls the saw blade 24 to stop rotating.
[0053] When in use, the mounting plate 3 can be moved to the edge of the base 1 to make it easier for staff to add frozen meat.
[0054] In summary, unlike traditional bone saws whose open structure causes meat scraps to splatter and requires operators to wear multiple protective gear such as goggles and aprons, this device uses a fully enclosed transparent mounting cover 31 and a flip cover 32 as a physical barrier design to control the splattered debris inside the equipment. Combined with the interlocking mechanism that automatically stops the machine when the flip cover 32 is opened, it reduces the time operators are exposed to dangerous areas, thereby preventing operators from being injured.
[0055] Traditional bone saws typically involve manual hand-held cutting of frozen meat, resulting in uneven thickness and only 5-8 cuts per minute. This device, however, uses a pusher and adjustment assembly to automatically cut frozen meat, achieving precise control over the cutting thickness. Combined with a reciprocating feed mechanism driven by a third motor 41, it shortens the single cutting time and improves the cutting efficiency of large pieces of frozen meat.
[0056] The transparent cover facilitates observation, the touch screen allows for intuitive parameter settings, and multiple preset parameters can be set for quick switching according to frozen meat processing needs; all contact parts are detachable for cleaning.
[0057] The device automatically clamps and fixes the frozen meat in position through the cooperation of the feeding component and the adjustment component. Then, the third motor 41 drives the mounting plate 3 to slide along the guide rail 11, so that the frozen meat actively passes through the saw blade 24 to complete the cutting. The whole process does not require the operator to hold the frozen meat close to the saw blade 24. From the source of operation, it avoids the operator's limbs from close contact with the high-speed rotating saw blade 24, and completely eliminates the hidden danger of "slipping and unstable force during hand feeding, causing the limbs to approach the saw blade 24".
[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
