[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figures 1 to 5The utility model provides a technical solution: a bone sawing machine with a protective structure, including a frame 1, a driving wheel 2 and a driven wheel 3 are rotatably connected inside the frame 1, and the driving wheel 2 and the driven wheel 3 are connected through a saw blade 4. A brake assembly 5 is provided inside the frame 1, and the brake assembly 5 is on the same side as the driving wheel 2. An operating table 6 is welded to the outer wall of the frame 1, and a splash plate 7 is welded to the surface of the operating table 6 on the side adjacent to the frame 1. The splash plate 7 is respectively fitted and connected to the two ends of the outer wall of the frame 1, and a collection box 8 is provided on one side of the operating table 6. The collection box 8 is connected to the bottom of the splash plate 7 on one side through a hook engagement. The operating table 6 is bolted to a first push plate 10 through a first electric telescopic rod 9 opened on the surface thereof, and a reciprocating screw 11 is rotatably connected inside the operating table 6. The reciprocating screw 11 is connected to a material fixing frame 12 through nuts and bolts opened on the surface thereof, and the material fixing frame 12 is fitted and connected to the surface of the operating table 6.
[0024] The brake assembly 5 includes a reverse screw 501, an upper brake pad 502 and a lower brake pad 503. The reverse screw 501 is rotatably connected to the inside of the frame 1 through a motor opened on the top of the frame 1. The reverse screw 501 is welded to the upper brake pad 502 and the lower brake pad 503 through nuts opened on its surface. The upper brake pad 502 and the lower brake pad 503 are respectively located at the upper and lower ends of the driving wheel 2.
[0025] The top wall and right side panel of the outside of the material fixing frame 12 are respectively installed with a second electric telescopic rod 1201, and one end of the second electric telescopic rod 1201 is welded with a limiting plate 1202. The limiting plate 1202 is welded with an adjustment block 1203 through a plurality of springs opened on its surface. The bottom wall inside the material fixing frame 12 is slidably connected with a second pushing plate 1204.
[0026] In this embodiment, Figure 2 As shown, the saw blade 4 forms a transmission structure through the driving wheel 2 and the driven wheel 3, and saw teeth are respectively provided on both sides of the saw blade 4, and slots for transmitting the saw blade 4 are respectively provided at the intersection of the frame 1 and the operating table 6; in the prior art, the principle of the bone sawing machine is to realize the cutting of the meat block under the transmission structure by the saw blade 4 sleeved on the surface of the driving wheel 2 and the driven wheel 3. In contrast, many saw blades 4 currently adopt a single-sided sawtooth structure, which can only cut the meat block from one side, and the raw materials that have been cut for the first time need to return to the initial point for a second cutting. This operation method not only increases the cumbersomeness of the operation process, but also increases the probability that the operator may touch the saw teeth in the process of moving the raw materials back and forth, thereby increasing the probability of danger. By adopting a double-sided sawtooth structure for the saw blade 4, the material fixing frame 12 that can clamp the meat block raw materials in the reciprocating structure provides the necessary conditions for realizing the purpose of double-sided cutting of the material.
[0027] In this embodiment, Figure 2 and Figure 3As shown, the upper brake pad 502 and the lower brake pad 503 are arc-shaped and have a rubber layer glued to the surface where they are in contact with the driving wheel 2, and the upper brake pad 502 and the lower brake pad 503 move relative to each other inside the frame 1 through the reverse screw 501 and the nut; the upper brake pad 502 and the lower brake pad 503 are made of high-strength and hardness steel, and when the reverse screw 501 rotates, the nut can respectively drive the upper brake pad 502 and the lower brake pad 503 to fit on the upper and lower ends of the driving wheel 2 under the relative motion structure, and in the event of an emergency, the movement of the saw blade 4 can be quickly stopped by this structure to reduce the risk of accidental injury, and the rubber layer on the surface of the upper brake pad 502 and the lower brake pad 503 can provide additional friction, increase the braking effect, and reduce the wear on the surface of the driving wheel 2 caused by contact with the driving wheel 2.
[0028] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, a channel for discharging materials is formed between the splash plate 7 and the material fixing frame 12, and the first push plate 10 is slidably connected to the channel through the first electric telescopic rod 9, and the collection box 8 is opposite to and located below the channel; since some debris may splash when the meat raw materials are cut under the high-speed transmission saw blade 4 structure, the addition of the splash plate 7 can effectively prevent such debris from splashing onto the ground, and the cut materials are accumulated at the channel opening between the splash plate 7 and the material fixing frame 12, and the cut parts can be pushed into the collection box 8 through the first push plate 10, effectively reducing the probability of manual contact with the surface of the operating table 6, thereby greatly improving the safety of the operating process, and the pushing process can be run simultaneously without stopping the machine, and the material extraction is completed during the cutting process, which ensures safety while also improving processing efficiency.
[0029] In this embodiment, Figure 4As shown, a pulley embedded in the operating table 6 is provided at the bottom of the material fixing frame 12, and the material fixing frame 12 forms a reciprocating transmission structure on the surface of the operating table 6 through the reciprocating screw 11; the current operation process of the bone sawing machine is mainly to manually push the material to complete the cutting, because precise hand control is required, and gloves may affect the operation of the equipment and are prone to hooking with the saw blade 4, so most operators do not wear gloves to cut meat on the premise of ensuring that their hands are clean and dry, but there are still certain risks in the operation process, by setting a material fixing frame 12 that fixes the meat raw material, and the material fixing frame 12 replaces the manual operation of moving the material back and forth through the mechanical transmission of the reciprocating screw 11, the raw material can be pushed at a uniform speed, this pushing method can ensure that the pushing of the meat raw material on the surface of the saw blade 4 is consistent, avoiding the inconsistent cutting section caused by uneven speed that may occur in manual pushing, and is more efficient than manual pushing, saving time and improving overall work efficiency.
[0030] In this embodiment, Figure 5 As shown, the bottom plate of the material fixing frame 12 adjacent to the saw blade 4 is longer than other panels, and the limit plate 1202 forms a telescopic structure inside the material fixing frame 12 through the second electric telescopic rod 1201, and the adjustment block 1203 forms an elastic reset structure through a spring; the material fixing frame 12 can replace manual fixing of the meat block, reduce the direct contact between the operator and the cutting end, and thus reduce the risk of accidental injury, and the telescopic structure of the limit plate 1202 inside the material fixing frame 12 through the second electric telescopic rod 1201, and the adjustment block 1203 on the surface of the limit plate 1202 that is deformable by the spring, both help the material fixing frame 12 to fix meat blocks of different shapes in an adjustable manner when in use, thereby improving the versatility of the material fixing frame 12, and the longer bottom plate on the front end of the material fixing frame 12 is set to enable the meat block to be pushed by the second pushing plate 1204 after the first cutting is completed, and the specific specifications of the material to be pushed out are clearly measured by the length of the bottom plate during the pushing process, so as to facilitate the saw blade 4 to cut the pushed-out part.
[0031] The use method and advantages of the utility model: When the bone sawing machine with a protective structure is used, the working process is as follows:
[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, firstly, the meat material to be cut is placed inside the material fixing frame 12, and the upper and right limit plates 1202 can be moved inside the material fixing frame 12 to fit the top and one side of the meat material through the second electric telescopic rod 1201, and the meat material is fixed inside the material fixing frame 12. Since the meat material belongs to different parts, the adjustment block 1203 has an automatic adjustment function in the spring structure, which can be automatically adjusted according to the different sizes and shapes of the meat material, and the meat material is fixed, and the power reciprocating screw 1 is started. 1 rotates, and the nut on its surface drives the material fixing frame 12 clamping the meat raw material to approach the saw blade 4. At the same time, the driving wheel 2 rotates under the drive of the servo motor, and the driven wheel 3 rotates under the connection with the saw blade 4 so that the saw blade 4 cuts the approaching raw material through the saw teeth on the surface under the transmission structure. The splash plates 7 on both sides effectively prevent the debris from splashing onto the ground. When the first cut meat raw material is transmitted to the other side of the operating table 6 through the material fixing frame 12, the operator can push the raw material forward by pushing the second pushing plate 1204, and can push the raw material forward by pushing the slightly longer The bottom plate on one side is used to clearly measure the specific specifications of the material pushed out. When the material fixing frame 12 is transmitted to the other side of the operating table 6 again through the transmission of the reciprocating screw 11, the saw teeth on the other side of the saw blade 4 can cut the pushed out part again. The whole piece of material is cut under the structure of progressive pushing and reciprocating transmission, avoiding the tediousness and insecurity of manual moving and cutting, and improving the overall work efficiency. The cut meat pieces will be accumulated in the channel formed between the splash plate 7 and the material fixing frame 12. The first electric telescopic rod 9 can be used to push the first push plate 10 to push the material forward to the inside of the collection box 8. The collection box 8 is a detachable structure for subsequent extraction of the internal material. If an emergency occurs during operation, the reverse screw 501 can be driven by the power supply to rotate it. Under the transmission structure of the nut, the upper brake pad 502 and the lower brake pad 503 are respectively driven to fit the upper and lower ends of the driving wheel 2 under the relative motion structure. By preventing the rotation of the driving wheel 2, the movement of the saw blade 4 is quickly stopped, reducing the risk of accidental injury.
[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
