Description

Technical Field

[0001] This application relates to the field of grinding devices, and more specifically to a grinding machine for a skinning knife used in slaughtering. Background Technology

[0002] Slaughtering knives are specialized knives with multiple serrated blades arranged roughly in a circle. These knives require specialized sharpening tools to repair worn edges, but common slaughter line knife edge repair equipment lacks a sharpening and cooling system. During operation, the grinding action of the grinding wheel generates significant heat that accumulates on the blade edge, often causing it to overheat and scorch, resulting in reduced edge hardness and insufficient sharpness.

[0003] Currently, most grinding machines equipped with cooling systems require a booster pump-like device to direct the coolant flow to the area to be cooled. The presence of this booster complicates the configuration of these grinding machines, increases costs, and requires a certain amount of installation space, resulting in a larger footprint.

[0004] On the other hand, most grinding machines set the grinding wheel speed to thousands of revolutions per minute (rpm) to achieve better grinding results. However, high speeds lead to further increases in heat, and without increasing coolant usage, the cutting tools are more prone to overheating and scorching. Therefore, it is desirable to equip grinding machines with flow control devices to ensure good grinding results while preventing a sharp increase in coolant consumption. However, most grinding machines equipped with cooling systems lack coolant flow control, especially those with pressurization devices. Since the pressurization device itself requires pressurization to force coolant flow, controlling the flow of high-pressure coolant is even more difficult, resulting in higher coolant consumption and increased production costs. Summary of the Invention

[0005] Therefore, embodiments of this application provide a special blade repair device for peeling knives equipped with a cooling device.

[0012] In one embodiment, the inlet pipe is connected to a closed coolant container, and the regrinding equipment also includes a pump for maintaining the internal air pressure of the cooling device during operation. The pump is located between the inlet pipe and the flow regulating valve.

[0013] In one embodiment, the inlet pipe is connected to a coolant container that can be opened from the top to replenish coolant;

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] For ease of description, in the embodiments of the second aspect of the present invention shown in the accompanying drawings, the inlet pipe is configured to be connected to a coolant container, and the coolant container can be opened from the top for convenient replenishment of coolant by the user. However, it is understood that the accompanying drawings of the embodiments of the present application are not intended to limit the scope of protection of this application. For example, in another embodiment of the second aspect of the present application, the inlet pipe is configured to be connected to an external coolant source, such as an external tap water source. Taking an external tap water source as an example, in this embodiment of the present application, the tap water source is in a normally open state, and the user only needs to adjust the flow regulating valve 630 to control the outflow / flow rate of water droplets.

[0039] Similarly, for clarity, the accompanying drawings do not show a magnifying glass with LEDs, but in an embodiment according to the first aspect of this application, the grinding apparatus also includes a magnifying glass with LEDs disposed on the grinding wheel enclosure 340 and extending upward above the blade placement platform so that the user can observe during grinding.

[0040] Similarly, in the accompanying drawings, although the infusion pump 650 is mounted on the equipment cabinet extension 810 and the flow regulating valve 630 is mounted on the grinding wheel extension platform 330, those skilled in the art will understand that the positions of the infusion pump 650 and the flow regulating valve 630 are not limited to the two locations mentioned above. For example, the infusion pump 650 and the flow regulating valve 630 may be located simultaneously on the equipment cabinet extension 810 or simultaneously on the flow regulating valve 630.

[0041] Similarly, although the accompanying drawings show a plastic baffle 700, those skilled in the art will understand that the plastic baffle 700 can be installed or not by the user depending on the circumstances.

[0042] In the embodiments of this application, "cutting edge" is defined as the notch between the two cutting edges 110.

[0043] refer to Figure 1 , Figure 1 A slaughtering and skinning knife 100 is shown, its shape approximating a serrated circle, with a section of the circumference having a concave arc towards the center, this arc being without serrations. These serrations distributed along the circumference constitute the blade 110 of the skinning knife. The back of the slaughtering and skinning knife 100 has a protrusion (not shown in the attached diagram). During the slaughtering and skinning of livestock, the protruding back of one skinning knife engages with the front of another skinning knife, and a transmission mechanism rotates the two blades to slaughter and skin the livestock. After slaughtering the livestock, some blades 110 may become damaged and dull, therefore requiring sharpening to make the blades 110 sharp again. Therefore, in order to accommodate the sharpening of the slaughtering peeling knife 100, the slaughtering peeling knife 100 has a hollow fixing hole 120 in the center for fixing the slaughtering peeling knife 100 on the sharpening platform for sharpening. During sharpening, the blade 110 that needs to be sharpened is generally aligned with the sharpening device. When a certain blade 110 is sharpened, the slaughtering peeling knife 100 can be rotated around the fixing hole 120 to sharpen the next blade 110, or the slaughtering peeling knife 100 can be directly removed from the sharpening platform.

[0044] refer to Figure 2 and Figure 3 , Figure 2 An exploded view of the blade placement platform is shown. Figure 3 This shows the blade locking lever engaging with the blade. Figure 2As can be seen, the threaded rotating part 422 cooperates with the central screw 429 located at the center of the blade placement platform 421, thereby fixing the butchering peeling knife. When sharpening the blade, the threaded rotating part 422 also serves as a grip for the user's right hand, allowing the user to control the movable handle 423 with their left hand while their right hand presses down / lifts the threaded rotating part 422 to move the movable connection part 420 against / away from the grinding wheel 320. The first butterfly screw 4261 is used to lock / loosen the threaded rotating part, and the second butterfly screw is used to control the sharpening depth of the blade; the quick-release knob 425 is used to adjust the pitch angle of the blade placement platform relative to the movable connection to correct the sharpening angle of the blade, and to lock the sharpening angle of the blade during sharpening; the movable handle 423 is connected to the blade locking rod 428. In the normal state, the blade locking rod 428 is engaged with the cutting edge of the blade 110 or the blade placement platform 421. Only when the user moves the movable handle 423 will the blade locking rod 428 disengage downward from the cutting edge of the blade 110. Figure 3 The cross-sectional shape of the blade locking rod 428 corresponds to the cross-sectional shape of the blade edge of the blade 110, which to a certain extent enables the blade locking rod 428 to prevent the skinning knife 100 used for slaughtering from rotating during sharpening.

[0045] Depend on Figure 2 The horizontal cross-sectional shape of the blade placement platform 421 corresponds to the cross-sectional shape of the slaughtering peeling knife 100, which is circular. The outer wall of the blade placement platform 421 partially encloses the blade placement platform 421 in the direction away from the grinding wheel 320. The height of the outer wall of the blade placement platform 421 is set to be higher than the height of the slaughtering peeling knife 100 when it is placed on the blade placement platform 421, so that the slaughtering peeling knife 100 can be completely surrounded by the blade placement platform 421 to prevent it from falling off the blade placement platform 421.

[0046] from Figure 3 It can be seen that the outlet of the liquid outlet pipe 640 is not aligned with the cutting edge 110 to be processed, but rather with the grinding wheel 320 that is against the cutting edge 110. A typical regrinding / grinding device equipped with a cooling system would directly spray coolant onto the cross-section of the workpiece to be processed. However, the regrinding device provided in this embodiment first applies coolant to the grinding wheel 320 in the form of droplets / low flow rate. The grinding wheel 320 rotates in the opposite direction (i.e., from below the cutting edge 110 towards above the cutting edge 110), causing the low-flow-rate coolant to move in the opposite direction to gravity to the contact surface between the cutting edge 110 and the grinding wheel 320 under the drive of the high-speed rotating grinding wheel 320.

[0047] The following will provide a first embodiment and a second embodiment, depending on the different cooling devices 600.

[0048] First Embodiment

[0049] Figure 4a and Figure 4b This is a front view of the first embodiment of this application. Figure 4a and Figure 4b The difference lies in the fact that the former's sheet metal 200 is not hidden, and the former is further away from the grinding wheel 320, while the latter is the opposite. Figure 4a In the middle, from top to bottom, the sheet metal body 200 is shown as having a flow adjustment knob 210, an emergency stop button, and a recessed metal input button. Furthermore, it can be viewed from... Figure 4a It can be seen that the sheet metal of the machine body has enclosed all devices except for the blade clamping platform 400.

[0050] exist Figure 4b The image clearly shows a DC micro water pump 660, a PWM signal generator 670, and a connecting pipe 620. The PWM signal generator 670 is electrically connected to the DC micro water pump 660, and most of the connecting pipe 620 is hidden within the base 500. The DC micro water pump 660 is connected to at least two connecting pipes 620; one connecting pipe 620 draws coolant from the base 500, and the other connecting pipe 620 delivers coolant to the outlet pipe 640 located below the blade placement platform 421. Figure 5 The image clearly shows the connection between the two connecting pipes 620 and the DC micro water pump 660.

[0051] Figure 5 The grinding wheel enclosure 340 is clearly shown. This enclosure forms a rectangular area to collect coolant that falls during the grinding process. A drainage structure, such as a drainage hole or a drainage trough, is also provided in this area. The bottom of this drainage structure is directly opposite the filter screen 520 (when the drawer-type bottom plate 510 is completely located in the base 500).

[0052] Figure 6a and Figure 6b This is a side view of the grinding device according to the first embodiment of this application. It can be seen that the movable connecting part 420 can rotate around the height-limiting bolt 411 as the center, so that the blade placement platform 421 moves away from / aggregates against the grinding wheel 320. Figure 6b In the diagram, the skinning knife 100 rests against the grinding wheel 320, and it can be seen that the second wing screw 4262 also rests against the screw baffle 412. When the second wing screw 4262 is rotated clockwise (i.e., tightened), the screw it controls will further rest against the screw baffle 412, thereby moving the movable connecting part 420 away from the grinding wheel 320 and preventing over-sharpening of the skinning knife 100. It can be understood that when deep sharpening of the skinning knife 100 is required, simply rotating the second wing screw 4262 counterclockwise is sufficient. Regarding... Figure 6a and Figure 6b The description also applies to the second embodiment of this application.

[0053] Figure 7a and Figure 7b This is a top view of the grinding apparatus according to the first embodiment of this application. Figure 7a In the image, it can be clearly seen that the connecting tube 620 extends from the base 500 to the blade clamping platform 400, and... Figure 7b As can be seen in the image, the filter screen 520 is located in the drawer-type bottom plate 510. When the slaughtering peeling knife 100 is being sharpened, the DC micro water pump 660 draws coolant from the area outside the filter screen 520, while the used coolant drips into the area where the filter screen 520 is located, preventing the DC micro water pump 660 from reusing the sharpened metal shavings for cooling and clogging the connecting pipe 620 and the outlet pipe 640.

[0054] Second Embodiment

[0055] refer to Figure 8 , Figure 8 This is a front perspective view of the regrinding equipment according to the second embodiment of this application, wherein the blade has been mounted on the blade placement platform. Generally, the regrinding equipment of this embodiment can be roughly divided into five parts: equipment cabinet 200, grinding device 300, blade clamping platform 400, base 500, cooling device 600, and plastic baffle 700. The plastic baffle is an optional component, its main function being to prevent the splashing of metal shavings and coolant droplets from falling from the blade during the regrinding process.

[0056] The base 500 provides support for the equipment cabinet 800, the grinding device 300, and the blade clamping platform 400. The cooling device 600 is distributed across the equipment cabinet 20, the grinding device 300, and the blade clamping platform 400. At the front of the equipment cabinet 800, there is a boss with buttons for operating the grinding equipment. For illustrative purposes, the boss is shown as having two buttons: a forward-protruding emergency stop button and an inward-recessed metal input button.

[0057] refer to Figure 9 , Figure 9This is a rear perspective view of the grinding equipment according to the second embodiment of this application, wherein the rear cover of the equipment cabinet 800 has been removed to show the internal components of the equipment cabinet 800. The interior of the equipment cabinet 800 is divided into an upper part housing the cooling device 600 and a lower part housing electrical components, wherein, for illustrative purposes, the electrical components are shown as overcurrent protection devices. In this embodiment, the inlet pipe 610 is shown as a coolant container passing through the top of the equipment cabinet 800. On the side of the equipment cabinet, a horizontally arranged equipment cabinet extension 810 is provided, and a liquid pump 650 is provided on the equipment cabinet extension 810; in order to facilitate the flow of coolant by gravity alone, the lowest part of the coolant container to which the inlet pipe 610 is connected is located at a horizontal plane higher than the horizontal plane of the equipment cabinet extension 810. The liquid pump 650 and the inlet pipe 610 are directly connected by a coolant connecting pipe 620 passing through the side wall of the equipment cabinet 800.

[0058] Refer to Figure 4 and Figure 4a And at the same time refer to Figure 9 Above the grinding wheel 320, i.e., on the outer shell surrounding the grinding wheel 320, a grinding wheel extension platform 330 is provided. The flow control valve 630 and the infusion pump 650 are connected via a coolant connecting pipe 620. In the second embodiment of this application, the flow control valve 630 is a roller. By pushing the roller to different positions, the roller presses against the coolant connecting pipe 620 located below it, thereby changing the flow path of the coolant connecting pipe 620 and achieving coolant flow / current control.

[0059] In one embodiment of the second embodiment, the rotational speed of the grinding wheel 320 is adjusted to 2800 rpm, and the coolant flow rate is adjusted to flow out drop by drop from the outlet pipe 640. In this case, all the coolant can directly act on the blade 110 without falling off due to gravity, thus minimizing coolant consumption. Furthermore, in this embodiment, although the coolant flow rate is adjusted to the minimum, the blade 110 does not experience a rapid temperature increase and scorching, thus not affecting the hardness or sharpness of the blade 110.

[0060] In the second embodiment of this application, the liquid outlet pipe 650 is shown as a rigid plastic pipe so that a plastic baffle 700 can be fitted onto it to prevent the user and equipment from being injured by splashing water droplets and metal fragments.

[0061] exist Figure 10aIn the diagram, the movable connecting part 420 is shown moving forward against the grinding wheel 320. When the blade needs to be re-sharpened, after the user fixes the blade and starts the equipment, they push the movable connecting part 420 downward. At this time, the movable connecting part 420 will rotate around the height limit bolt 411 as the rotation axis until the blade 110 abuts against the grinding wheel 320. After the blade 110 is re-sharpened, simply pull the movable connecting part 420 backward, and the movable connecting part 420 will move away from the grinding wheel 320, thereby disengaging the cutting edge of the blade 110 from the grinding wheel 320.

[0062] The second embodiment of this application, by setting a cooling device 600, allows the coolant to flow to the cross-section of the workpiece to be processed solely under gravity, eliminating the need for a coolant pressurization device and saving on the construction cost, device complexity, and equipment installation space of the grinding device. This embodiment also maximizes the utilization rate of the coolant by aligning the outlet pipe 640 with the grinding wheel 320 below the cutting edge 110 and using a flow regulating valve 630, thus reducing the amount of coolant consumed in a single grinding cycle. Furthermore, this embodiment proposes an inlet pipe 610. When the inlet pipe 610 is connected to a coolant container, it allows for convenient coolant filling. The inlet pipe 610 is also configured to connect to an external coolant source, avoiding frequent coolant filling later.

[0063] The process of a user sharpening a blade using the sharpening equipment of this application embodiment is as follows:

[0064] The slaughtering peeling knife 100 is fixed on the blade placement platform 210, that is, the fixing hole 120 is aligned with the center screw 429, and then the threaded rotating part 422 is aligned with the center screw 429 and the threaded rotating part 422 and the first wing screw 4261 are rotated to tighten the slaughtering peeling knife 100; the adjustment quick knob 425 is turned to adjust the sharpening angle of the slaughtering peeling knife 100; the second wing screw 4262 is adjusted to adjust the sharpening depth of the slaughtering peeling knife 100;

[0065] Align the blade 110 that needs to be sharpened with the grinding wheel 320 of the sharpening equipment, and at the same time move the movable handle 423 so that the blade locking rod 428 engages with the cutting edge of the adjacent blade 110 of the blade 110 that needs to be sharpened, so as to prevent the blade from rotating in the circumferential direction during sharpening.

[0066] Adjust the flow control knob / flow control valve to allow the coolant to flow out at a certain flow rate as needed.

[0067] Turn on the motor 310 of the grinding equipment to make the grinding wheel 330 rotate;

[0068] The movable connecting part 420 is rotated forward so that the blade abuts against the grinding wheel 320 to sharpen the blade 110.

[0069] Rotate the connecting part 420 backward to separate the blade from the grinding wheel 320. If it is necessary to sharpen another blade 110, loosen the first wing screw 4261, turn the movable handle 423, and rotate the threaded rotating part 422 along the circumference of the blade to replace the blade 110 that needs to be sharpened. If no further sharpening is needed, turn off the motor 310 and the flow regulating valve 630.

[0070] The above is a description of the embodiments of this application, but this application is not limited to the above-described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this application, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
