Description

Technical Field

[0001] The present invention relates to the technical field of shell cutting, and more particularly to a pearl shell plate cutting machine. Background Art

[0002] Pearl oysters produce high-quality, full-bodied pearls and are the primary carrier of cultured pearls. After pearls are removed from the oysters, the remaining shells are mostly discarded as aquaculture waste, a significant waste of resources and environmental pollution caused by the decay of the discarded shells. Pearl oysters typically range in size from 7cm to 25cm, with some even growing to over 30cm. They possess a beautiful, unique luster, fine grains, a dense structure, high compressive strength, and excellent machinability and fire resistance, making them suitable for the production of shell crafts and interior architectural decoration materials, boasting both high ornamental value and practical value. Therefore, to avoid waste, pearl oysters are often made into crafts or used as architectural decoration materials. To create crafts or architectural decoration materials, pearl oysters typically undergo cutting, grinding, and polishing processes before being processed into pearl shell slabs. These slabs are the basic building blocks for these crafts and architectural decoration materials. After cutting, they are then glued and spliced ​​together to create these crafts and architectural decoration materials.

[0003] Currently, most manufacturers use traditional single-blade saws to cut pearl shells. Workers visually inspect the shells and manually adjust the cutting position. This method cuts the shells piece by piece. Due to the uneven shape of the shells, the force applied during the cutting process is uneven, which can easily cause cracks on the surface. Furthermore, this manual cutting method is inefficient, labor-intensive, and can lead to dimensional inaccuracies in the resulting plates, resulting in inconsistent shapes. Summary of the Invention

[0004] The object of the present invention is to overcome the shortcomings of the prior art in that pearl shell plates are prone to cracks during the cutting process, have low production efficiency, and have errors in the size of the cut plates. A pearl shell plate cutting machine is provided. When the pearl shell plate cutting machine of the present invention cuts pearl shells, cracks are not easily generated on the surface of the pearl shells, and the cutting efficiency is high, and the dimensional error of the plates is small.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: A pearl shell plate cutting machine is provided, comprising a frame, a driving unit, a first cutting unit for cutting shell plates into shell strips, and a second cutting unit for cutting shell strips into shell blocks, wherein the first cutting unit and the second cutting unit are both fixedly mounted on the frame; The first cutting part includes a first cutting wheel and a first feeding wheel capable of driving the shell plate to be cut by the first cutting wheel, and the first feeding wheel and the first cutting wheel are both rotatably connected to the frame; The second cutting part includes a second cutting wheel and a second feeding wheel capable of driving the shell strips to be cut by the second cutting wheel, and the second feeding wheel and the second cutting wheel are both rotatably connected to the frame; The first cutting blade of the first cutting wheel and the second cutting blade of the second cutting wheel are both diamond cutting blades; the first feed wheel is a polyurethane wheel; and the second feed wheel is a rigid wheel; The driving part is fixedly mounted on the frame, and the driving part is connected to the first cutting part and the second cutting part.

[0006] The second feed wheel is a cast iron wheel. The driving part is connected with the first cutting wheel and the first feed wheel in the first cutting part and the second cutting wheel and the second feed wheel in the second cutting part.

[0007] When the pearl shell plate cutting machine of the present invention is working, the driving part on the frame controls the first cutting part and the second cutting part to start working. When the first cutting part is working, the first feed wheel and the first cutting wheel rotate. After the staff puts the shell plate to be cut between the first feed wheel and the first cutting wheel, the first feed wheel rotates to drive the shell plate into the cutting area of ​​the first cutting wheel. The first cutting wheel rotates to enable the first cutting blade to cut the shell plate, and cuts the shell plate into shell strips; when the second cutting part is working, the second feed wheel and the second cutting wheel rotate. After the staff puts the shell strip to be cut between the second feed wheel and the second cutting wheel, the second feed wheel rotates to drive the shell strip into the cutting area of ​​the second cutting wheel. The second cutting wheel rotates to enable the second cutting blade to cut the shell strip, and cuts the shell strip into shell slices.

[0008] The pearl shell slab cutting machine of the present invention uses a polyurethane feed wheel to drive the shell slab to be cut by a diamond cutting blade. The polyurethane wheel has a certain toughness. During the process of cutting the shell slab into shell strips, the vibration of the shell slab can be absorbed by the first feed wheel, preventing the shell from cracking due to excessive vibration during the cutting process, which may lead to shell damage. During the process of cutting the shell strip into shell slices, due to the narrow width of the shell strip and the short cutting time, the vibration generated during the cutting process is not enough to cause cracks in the shell strip. Therefore, the second feed wheel is made of a rigid material. In addition, the high hardness of diamond makes it a smooth incision when used as a cutting blade.

[0009] The specific data comparison is as follows. 1000 shells were grouped together and the pearl shell plate cutting machine of the present invention and the conventional cast iron wheel cutting machine were used to cut the shells. The results of the ten groups of experiments were statistically analyzed. The statistical results are shown in Table 1.

[0010] Table 1 - Crack rate statistics when using the cutting machine of this application and the commonly used cast iron wheel cutting machine to cut shell strips and shell sheets It can be seen from Table 1 that, compared with the existing conventional cast iron wheel cutting machine for cutting pearl shells, the pearl shell plate cutting machine of the present application can significantly reduce the number of cracks generated in pearl shells when cutting pearl shells, and the yield of the cutting is higher.

[0011] In addition, the pearl shell plate cutting machine of the present invention adopts a double-station to cut the pearl shells. First, the large-sized shell plates are cut into strips, and then the shell strips are further cut into the required shell plates. This can avoid the stress concentration of the shell when cutting small pieces directly in thin or irregular areas, causing the shell to break, break or produce microcracks during the cutting process, thereby improving the yield of material cutting.

[0012] In summary, the pearl shell plate cutting machine of the present invention is not prone to cracks on the shell surface during cutting, and has high cutting efficiency and small dimensional error of the plate, which can improve the efficiency and yield of shell plate cutting, and can make high-value use of a large number of discarded low-value pearl shells, transforming them into high-quality, multi-functional interior decoration materials and shell handicrafts, thereby increasing the income of pearl farmers, extending the pearl industry chain, promoting the upgrading and transformation of my country's pearl industry, and promoting the high-quality development of the pearl industry.

[0013] Furthermore, there are a plurality of first cutting blades, and the plurality of first cutting blades are linearly arranged on the first cutting wheel along the axis of the first cutting wheel, and the distance between two adjacent first cutting blades is adjustable; There are a plurality of second cutting blades, and the plurality of second cutting blades are linearly arranged on the second cutting wheel along the axis of the second cutting wheel, and the distance between two adjacent second cutting blades is adjustable.

[0014] The first cutting wheel includes a first axle and a plurality of first cutting blades, which are linearly arranged on the first axle along the axis of the first axle. A sleeve is provided between two adjacent first cutting blades, which is fixedly mounted on the first axle. The sleeve serves to separate the first cutting blades, thereby maintaining a constant gap between the two adjacent first cutting blades. When the gap between the two adjacent first cutting blades needs to be adjusted, the spacing between the two adjacent first cutting blades can be changed by replacing sleeves of different sizes. Similarly, the second cutting wheel also includes a second axle and a plurality of second cutting blades. A sleeve is also provided between two adjacent second cutting blades, which is fixedly mounted on the second axle. When the distance between the two adjacent second cutting blades needs to be adjusted, the sleeves of different sizes can be replaced.

[0015] The spacing between the cutting blades on the first cutting wheel and the second cutting wheel is adjustable, and the spacing between two adjacent cutting blades can be adjusted according to actual needs, thereby producing shell strips and shell plates of different sizes.

[0016] Furthermore, the second feed wheel is provided with an escape groove for accommodating the second cutting blade and a receiving groove for accommodating the shell strip, and the axis of the receiving groove is parallel to the axis of the second feed wheel. After the shell strip cut from the first cutting portion is placed in the receiving groove, the shell strip can be fed into the cutting area of ​​the second cutting wheel as the second feed wheel rotates. The second feed wheel is also provided with an escape groove for accommodating the second cutting blade. When the second feed wheel and the second cutting wheel are both mounted on the frame, the edge of the second cutting blade can extend into the escape groove, and the length of the second cutting blade extending into the escape groove is greater than the depth of the receiving groove. When the second feed wheel rotates until the shell strip in the receiving groove rotates onto the second cutting blade, the second cutting wheel can cut the shell strip in the receiving groove into shell slices. The provision of the receiving groove enables the second feed wheel to smoothly drive the shell strip to the cutting area of ​​the second cutting blade, and the provision of the escape groove enables the second cutting wheel to smoothly cut the shell strip in the receiving groove.

[0017] Furthermore, the first cutting part further includes a first feeding tray capable of supporting shell plates and a first receiving box capable of collecting shell strips, and the first feeding tray, the first feeding wheel, the first cutting wheel and the first receiving box are fixed to the frame in sequence; The second cutting part also includes a second feeding tray that can support shell strips and a second receiving box that can collect shell pieces. The second feeding tray, the second feeding wheel, the second cutting wheel and the second receiving box are fixed to the frame in sequence.

[0018] When the cutting machine is in operation, workers place shell sheets onto the first feed wheel. As the first feed wheel rotates, the shell sheets are fed into the cutting area of ​​the first cutting wheel, which then cuts the shell sheets into shell strips. This completes the first cut of the shell sheet. If needed, the shell strips can be used as interior decoration materials and raw materials for shell crafts. If further cutting is required, the shell strips are placed on the second feed wheel, which drives the shells into the cutting area of ​​the second cutting wheel, which then cuts the shell strips into shell sheets.

[0019] The setting of the feeding tray makes it convenient for the staff to take the shell plates or shell strips; the setting of the collecting box makes it convenient to store the cut shell strips or shell plates.

[0020] Furthermore, the first cutting part further comprises a first material guide trough fixedly mounted on the frame, one end of the first material guide trough being connected to the discharge end of the first cutting wheel, and the other end being connected to the first material receiving box.

In the vertical direction, the end of the second material guide trough connected to the second cutting wheel is higher than the end connected to the second material receiving box, and the second feed wheel and the second cutting wheel are both located directly above the second material guide trough.

[0021] The shell strips cut by the first cutting unit fall onto the first guide trough and, under the action of their own weight, move downward along the first guide trough until they fall into the first receiving box. The shell sheets cut by the second cutting unit fall from the second feed wheel onto the second guide trough and, under the action of their own weight, move downward along the second guide trough until they fall into the second receiving box, completing the cutting process from shell sheets to shell sheets.

[0022] The setting of the material guide trough can make the shell strips automatically enter the first material receiving box smoothly, and the shell plates automatically enter the second material receiving box smoothly, thereby completing the automatic storage of the products.

[0023] Furthermore, it includes a protective cover, a water tank, a water pump, and a spray head.

The spray head is fixedly mounted on the protective cover, the water tank is fixedly mounted on the frame, and the water pump is fixedly mounted in the inner cavity of the water tank. The spray head and the water pump are connected by a water pipe. There are two spray heads, and the two spray heads can spray the first and second cutting wheels respectively. After the water pump pumps the water flow in the water tank into the spray heads, the spray heads spray the first and second cutting wheels. The spraying of the spray heads can provide cooling, lubrication, and dust reduction. The provision of the protective cover can further prevent the splashing of powder and water droplets.

[0024] Furthermore, the first material receiving box and the second material receiving box are respectively fixedly installed at the two ends of the inner cavity of the water tank, and the bottom surfaces of the first material receiving box and the second material receiving box are arrayed with a plurality of drainage holes. The first material receiving box and the second material receiving box are both installed in the inner cavity of the water tank, which can make the water tank have a larger volume to hold more water and provide more sufficient water for spraying. The setting of the drainage holes at the bottom of the first material receiving box and the second material receiving box can drain the cut products, so that the water on the surface of the product can re-enter the water tank to complete the water circulation and achieve the purpose of saving water. At the same time, the water sprayed by the sprinkler head can also re-enter the water tank along the material guide trough after spraying on the cutting part, further saving water. The water level in the water tank does not exceed the bottom surface of the material receiving box.

[0025] Furthermore, it also includes a dust collection bag that can collect dust. The dust collection bag is fixedly installed on the protective cover. There are two dust collection bags, which are respectively installed on the protective cover at positions corresponding to the first cutting wheel and the second cutting wheel. At this time, the dust particles generated by the cutting wheel after cutting and the water droplets carrying dust can be splashed into the dust collection bag as the cutting wheel rotates. The dust is collected in the dust collection bag, and the water droplets can pass through the collection bag and return to the water tank.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0033] Example 1 This embodiment is the first embodiment of a pearl shell plate cutting machine. Figure 1 、 Figure 2 and Figure 7 As shown, it includes a frame 1, a driving part, a first cutting part for cutting the shell plate into shell strips, and a second cutting part for cutting the shell strips into shell blocks, and the first cutting part and the second cutting part are both fixedly mounted on the frame 1; The first cutting part includes a first cutting wheel 2 and a first feeding wheel 5 that can drive the shell plate to be cut by the first cutting wheel 2. The first feeding wheel 5 and the first cutting wheel 2 are both rotatably connected to the frame 1. The second cutting part includes a second cutting wheel 3 and a second feeding wheel 8 that can drive the shell strips to be cut by the second cutting wheel 3. The second feeding wheel 8 and the second cutting wheel 3 are both rotatably connected to the frame 1. The first cutting blade 201 of the first cutting wheel 2 and the second cutting blade 301 of the second cutting wheel 3 are both diamond cutting blades; the first feed wheel 5 is a polyurethane wheel; and the second feed wheel 8 is a rigid wheel; The driving part is fixedly mounted on the frame 1 and is connected to the first cutting part and the second cutting part.

[0034] The working principle or working process of this embodiment is as follows: When the pearl shell plate cutting machine of this embodiment is working, the driving part on the frame controls the first cutting part and the second cutting part to start working. When the first cutting part is working, the first feed wheel 5 and the first cutting wheel 2 rotate. After the staff puts the shell plate to be cut between the first feed wheel 5 and the first cutting wheel 2, the first feed wheel 5 rotates to drive the shell plate into the cutting area of ​​the first cutting wheel 2. The first cutting wheel 2 rotates to make the first cutting blade 201 cut the shell plate and cut the shell plate into shell strips; when the second cutting part is working, the second feed wheel 8 and the second cutting wheel 3 rotate. After the staff puts the shell strip to be cut between the second feed wheel 8 and the second cutting wheel 3, the second feed wheel 8 rotates to drive the shell strip into the cutting area of ​​the second cutting wheel 3. The second cutting wheel 3 rotates to make the second cutting blade 301 cut the shell strip and cut the shell strip into shell slices.

[0035] The beneficial effects of this embodiment are as follows: The pearl shell plate cutting machine of this embodiment uses a polyurethane feed wheel to drive the shell plate to be cut by the diamond cutting blade. The polyurethane wheel has a certain toughness. During the process of cutting the shell plate into shell strips, the vibration of the shell plate can be absorbed by the first feed wheel, thereby preventing cracks from forming on the surface of the shell due to excessive vibration during the cutting process, thereby causing damage to the shell.

[0036] Therefore, the pearl shell plate cutting machine of this embodiment is not prone to cracks on the shell surface during cutting, and has high cutting efficiency and small dimensional error of the plate, which can improve the efficiency and yield of shell plate cutting, and can make high-value use of a large number of discarded low-value pearl shells, transforming them into high-quality, multi-functional interior decoration materials and shell handicrafts, thereby increasing the income of pearl farmers, extending the pearl industry chain, promoting the upgrading and transformation of my country's pearl industry, and promoting the high-quality development of the pearl industry.

[0037] Example 2 This embodiment is a second embodiment of a pearl shell plate cutting machine. Figures 1-8 As shown, this embodiment further defines the structures of the first cutting part, the second cutting part and the frame 1 on the basis of the first embodiment.

[0038] Specifically, the first cutting wheel 2 includes a first axle 202 and a plurality of first cutting blades 201. The plurality of first cutting blades 201 are linearly arranged on the first axle 202 along the axis of the first axle 202. A sleeve 23 is provided between two adjacent first cutting blades 201. The sleeve 23 is fixedly mounted on the first axle 202 and serves to separate the first cutting blades 201, maintaining a constant gap between the two adjacent first cutting blades 201. When the gap between the two adjacent first cutting blades 201 needs to be adjusted, the sleeve 23 of a different size can be replaced to change the spacing between the two adjacent first cutting blades 201. Similarly, the second cutting wheel 3 also includes a second axle 302 and a plurality of second cutting blades 301. A sleeve 23 is also provided between two adjacent second cutting blades 301. The sleeve 23 can be fixedly mounted on the second axle 302. When the distance between the two adjacent second cutting blades 301 needs to be adjusted, the sleeve 23 of a different size can be replaced.

[0039] Specifically, the second feed wheel 8 is provided with a clearance groove 801 for accommodating the second cutting blade 301 and a receiving groove 802 for accommodating the shell strip, and the axis of the receiving groove 802 is parallel to the axis of the second feed wheel 8.

[0040] Specifically, the first cutting part also includes a first feeding tray 4 that can support shell plates, a first receiving box 6 that can collect shell strips, and a first guide trough 10 fixedly mounted on the frame 1. The first feeding tray 4, the first feeding wheel 5, the first cutting wheel 2, and the first receiving box 6 are fixed to the frame 1 in sequence; One end of the first material guide chute 10 is connected to the discharge end of the first cutting wheel 2, and the other end is connected to the first material receiving box 6. In the vertical direction, the end of the first material guide chute 10 connected to the first cutting wheel 2 is higher than the end connected to the first material receiving box 6. The first feed wheel 5 and the first cutting wheel 2 are both located directly above the first material guide chute 10. The second cutting part also includes a second feeding tray 7 for supporting shell strips, a second receiving box 9 for collecting shell pieces, and a second material guide trough 11 fixedly mounted on the frame 1. The second feeding tray 7, the second feeding wheel 8, the second cutting wheel 3 and the second receiving box 9 are fixed to the frame 1 in sequence; One end of the second material guide trough 11 is connected to the discharge end of the second cutting wheel 3, and the other end is connected to the second material receiving box 9. In the vertical direction, the end of the second material guide trough 11 connected to the second cutting wheel 3 is higher than the end connected to the second material receiving box 9, and the second feed wheel 8 and the second cutting wheel 3 are both located directly above the second material guide trough 11.

[0041] The first feed wheel 5 and the first cutting wheel 2 are both located directly above the first material guide trough 10, that is, the projections of the first feed wheel 5 and the first cutting wheel 2 in the vertical direction are located on the first material guide trough 10; the second feed wheel 8 and the second cutting wheel 3 are both located directly above the second material guide trough 11, that is, the projections of the second feed wheel 8 and the second cutting wheel 3 in the vertical direction are located on the second material guide trough 11.

[0042] The working principle or working process of this embodiment is as follows: The drive unit drives the first and second feed wheels 5 and 8. When the cutting machine is in operation, the worker first places the shell to be cut on the first feed tray 4, then sequentially places the shell slabs on the first feed wheel 5. As the first feed wheel 5 rotates, the shell slabs are fed into the cutting area of ​​the first cutting wheel 2, which cuts the shell slabs into shell strips. The shell strips emerging from the first cutting wheel 2 fall into the first guide trough 10. Under the influence of their own weight, the shell strips move downward along the first guide trough 10 until they fall into the first receiving bin 6. This completes the first cut of the shell slabs.

[0043] If necessary, the shell strips can be used as raw materials for interior decoration and shell crafts. If the shell strips need to be further cut, the shell strips in the first receiving box 6 are taken out and placed on the second feeding tray 7. Then the staff will place the shell strips on the second feeding tray 7 on the second feeding wheel 8. The second feeding wheel 8 drives the shell strips to move to the cutting area of ​​the second cutting wheel 3. The second cutting wheel 3 cuts the shell strips and cuts them into shell sheets. The cut shell sheets fall out of the second cutting wheel 3 and fall onto the second guide trough 11. Under the action of the shell sheet's own gravity, the shell sheet moves downward along the second guide trough 11 until the shell sheet falls into the second receiving box 9. At this time, the cutting from shell sheet to shell sheet can be completed.

[0044] The process of the second cutting wheel 3 cutting the shell strips is as follows: after the shell strips cut from the first cutting part are placed in the receiving groove 802, the shell strips can be fed into the cutting area of ​​the second cutting wheel 3 as the second feed wheel 8 rotates. The second feed wheel 8 is also provided with an air avoidance groove 801 that can accommodate the second cutting blade 301. When the second feed wheel 8 and the second cutting wheel 3 are both installed on the frame 1, the edge of the second cutting blade 301 can extend into the air avoidance groove 801 and the length of the second cutting blade 301 extending into the air avoidance groove 801 is greater than the depth of the receiving groove 802, so that when the second feed wheel 8 rotates until the shell strips in the receiving groove 802 rotate onto the second cutting blade 301, the second cutting wheel 3 can cut the shell strips in the receiving groove 802 and cut the shell strips into shell pieces.

[0045] The beneficial effects of this embodiment are as follows: The first feed wheel 5 is a soft rubber wheel or a soft polyester wheel, and its surface has friction. When the shell plate is fed into the bottom surface of the first feed wheel 5, the friction between the first feed wheel 5 and the shell plate can drive the shell plate to continue to move forward. The spacing between the cutting blades on the first cutting wheel 2 and the second cutting wheel 3 is adjustable. The spacing between two adjacent cutting blades can be adjusted according to actual needs, thereby producing shell strips and shell plates of different sizes. The setting of the receiving groove 802 on the second feed wheel 8 enables the second feed wheel 8 to smoothly drive the shell strip to the cutting area of ​​the second cutting blade 301, and the setting of the avoidance groove 801 enables the second cutting wheel 3 to smoothly cut the shell strip in the receiving groove 802.
