Description

Technical Field

[0001] The invention belongs to the field of silicon rod slicing, and in particular relates to a multi-station slicing machine. Background Art

[0002] Silicon wafer forming refers to the process of turning silicon rods into silicon wafers. At present, the most common method for slicing is multi-wire cutting. In the actual production process, the slicer often has only one cutting area assembly, that is, one cutting area, and one cutting area can only form one cutting station. This results in one cutting cycle only being able to cut hard and brittle materials on a single cutting station, which seriously limits the cutting capacity and efficiency of the slicer; increasing the number of slicers to improve the cutting capacity and efficiency will bring the problem of occupying more plant land area. Many companies cannot expand their production scale because they cannot expand the plant area; increasing the number of slicers also means increasing the investment in equipment funds, which is also a factor that makes it difficult for companies to expand their production scale for high-priced slicers; the realization of the heat exchange function of the slicer requires many pipelines to circulate, and the existing equipment pipelines are relatively scattered, which is not conducive to management; the existing slicers usually require professional technicians to carry out on-site installation work for several weeks, which is not conducive to serving long-distance customers, and the technical level of the installers is required to be high, so the personnel cost is also high.

[0003] Therefore, the prior art needs to be further developed and improved. Summary of the invention

[0004] In view of the various deficiencies of the prior art and in order to solve the above problems, a multi-station slicer is now proposed. The present invention provides the following technical solutions:

[0005] A multi-station slicer comprises at least two cutting area assemblies for slicing and a liquid circuit assembly respectively arranged corresponding to each cutting area assembly and used for providing cutting liquid and cooling liquid. The multiple liquid circuit assemblies are centrally arranged.

[0006] Furthermore, each cutting area assembly is arranged in a centrally symmetrical or bilaterally symmetrical manner.

[0007] Furthermore, the multi-station slicer is a double-station slicer including two cutting area assemblies, the two cutting area assemblies are arranged symmetrically on the left and right, and the liquid circuit assembly and the electrical assembly are located in the middle of the two cutting area assemblies.

[0011] Furthermore, the cutting liquid supply assembly includes a cutting liquid supply cylinder for storing cutting liquid of the corresponding connected cutting area assembly and a liquid supply pump for pumping the cutting liquid to the corresponding cutting area assembly. Each cutting liquid supply cylinder is provided with a liquid supply pump, and each liquid supply pump pumps the cutting liquid in the cutting liquid supply cylinder to the corresponding cutting area assembly.

[0012] Furthermore, the centralized cooling component includes a cooling liquid heat exchange component for cooling the slicer equipment and a cutting fluid heat exchange component for cooling the cutting fluid.

[0013] Furthermore, the coolant heat exchange component includes a coolant water tank for storing coolant, a coolant pump for pumping coolant and a coolant heat exchanger for cooling the coolant. The coolant flowing through the cutting area assembly equipment is cooled by the coolant heat exchanger and then flows back to the coolant water tank.

[0014] Furthermore, the cutting fluid heat exchange component includes a filter barrel for filtering and pumping the cutting fluid and a cutting fluid heat exchanger for cooling the cutting fluid. The cutting fluid is first filtered by the filter barrel and then flows into the cutting fluid heat exchanger for cooling, and then transported to the corresponding cutting area.

[0015] Furthermore, each cutting area assembly is physically connected via the same connection structure, and the liquid circuit assembly is connected to each cutting area assembly as a whole via the connection structure.

[0016] Furthermore, each cutting area assembly is detachably connected to the connection structure, and the connection structure is provided with connection sites for connecting each cutting area assembly. At the same time, the connection structure is also provided with reserved connection sites for connecting more cutting area assemblies.

[0017] Furthermore, the connecting structure is a connecting beam or a connecting frame.

[0018] Furthermore, the cutting area assembly includes a protection mechanism and a feeding mechanism and a wire saw mechanism located inside the protection mechanism.

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0043] like Figure 1-17 As shown, a multi-station slicer includes at least two cutting area assemblies 100 for slicing and a liquid circuit assembly 200 for providing cutting liquid and cooling liquid respectively arranged corresponding to each cutting area assembly 100, and the multiple liquid circuit assemblies 200 are arranged in a centralized manner. By centrally arranging multiple liquid circuit assemblies 200, the overall integration of the slicer equipment is improved, and multiple cutting area assemblies 100 are arranged outside the centralized area of ​​the liquid circuit assembly 200, so that each cutting area assembly 100 can obtain the cutting liquid and cooling liquid required for cutting from one liquid circuit assembly 200, thereby achieving the multi-station goal of the slicer equipment, and greatly reducing the occupied area, improving the utilization rate of the plant space, and increasing the production capacity per unit area by multiple times.

[0044] Furthermore, each cutting area assembly 100 is arranged in a central symmetric or bilateral symmetric manner. The symmetric arrangement is conducive to effectively managing each cutting area assembly 100 with a regular arrangement, facilitating enterprise management, and optimizing the use of plant space, with the least land and equipment cost investment, and most efficiently improving the production capacity per unit area.

[0045] Furthermore, the multi-station slicer is a double-station slicer including two cutting area assemblies 100, the two cutting area assemblies 100 are arranged symmetrically, and the liquid circuit assembly 200 and the electrical assembly are located in the middle of the two cutting area assemblies 100. The double-station slicer is the optimal mode among the multi-station slicers. The plant space occupied by the double-station slicer is smaller than the whole equipment space of the original slicer, so that the production capacity can be doubled directly by replacing the equipment without changing the plant area. The double-station slicer uses a complete set of liquid circuit assemblies 200 and electrical assemblies that are centrally arranged in the middle of the two cutting area assemblies 100. The double-station slicer can use one of them alone for cutting work, and the other liquid circuit assembly 200 and electrical assembly do not need to be opened, so there will be no waste of resources. The oil and gas assembly provides hydraulic boosting, running-in lubrication, gas circuit sealing and other functions for each device of the slicer. The oil and gas assembly includes a hydraulic component, a pneumatic component and an oil and gas component. The hydraulic component mainly provides hydraulic boosting for equipment parts. The pneumatic components are mainly used for air path backflush and air path sealing for equipment parts. Among the oil and gas components, one part is mainly used to provide air path sealing and regulate air pressure for equipment parts; the other part provides lubricating oil to equipment bearing parts through oil pipes to achieve running-in lubrication.

[0046] Furthermore, the electrical assembly includes an electrical control cabinet 310 centrally arranged on one side or an electrical control cabinet 310 respectively arranged on both sides based on the two cutting area assemblies 100. Each cutting area assembly 100 is equipped with a set of electrical assemblies, and the two sets of electrical assemblies can be respectively provided with electrical control cabinets 310 for protection and distinction, or they can be placed in one electrical control cabinet 310 for integrated operation. The layout of two electrical control cabinets 310 arranged between the two cutting area assemblies 100 is as follows: the two electrical control cabinets 310 are both fixed on the connection structure and are respectively located on both sides of the connection structure, one of the electrical control cabinets 310 is arranged on the top of the centralized cooling component, and the other electrical control cabinet 310 is arranged on the top of the oil and gas assembly. The layout of an electrical control cabinet 310 arranged between the two cutting area assemblies 100 is as follows: the electrical control cabinet 310 is fixed on one side of the connection structure, and the liquid circuit assembly 200 and the oil and gas assembly are both arranged on the other side of the electrical control cabinet 310. An operation box 320 is also provided on each cutting area assembly 100. The operation box 320 is connected to the electrical assembly signal in the electrical control cabinet 310 to provide a human-machine interface and signal input for the electrical control cabinet 310, so as to facilitate the operator to set the cutting process.

[0047] Furthermore, the liquid circuit assembly 200 includes a cutting liquid supply assembly 210 for providing cutting liquid and a centralized cooling assembly for cooling equipment and cutting liquid. The cutting liquid in the cutting liquid supply assembly 210 is input into the corresponding centralized cooling assembly through a pipeline. The liquid outlet pipe of the cutting liquid supply assembly 210 is connected to the centralized cooling assembly, and the centralized cooling assembly cools the liquid output by the cutting liquid supply assembly 210 and then delivers it to each cutting area assembly 100.

[0048] Furthermore, multiple cutting liquid supply assemblies 210 are arranged side by side, and the centralized cooling assembly is centrally arranged above the cutting liquid supply assembly 210. Taking a double-station slicer as an example, two cutting liquid supply assemblies 210 are arranged side by side. When the electric control cabinet 310 is arranged on both sides of the connection structure, the two centralized cooling assemblies are arranged behind the cutting liquid supply assembly 210, and the corresponding two electric control cabinets 310 are arranged above the centralized cooling assembly and the cutting liquid supply assembly 210, respectively, so as to maximize the use of the space between the two cutting area assemblies 100; when the electric control cabinet 310 is arranged on one side of the connection structure, the two centralized cooling assemblies are arranged above the two side-by-side cutting liquid supply assemblies 210, and the upper and lower structures are optimized to save space.

[0049] Furthermore, the cutting liquid supply assembly 210 includes a cutting liquid supply cylinder 211 for storing the cutting liquid of the corresponding connected cutting area assembly 100 and a liquid supply pump 212 for pumping the cutting liquid to the corresponding cutting area assembly 100. Each cutting liquid supply cylinder 211 is provided with a liquid supply pump 212, and each liquid supply pump 212 pumps the cutting liquid in the cutting liquid supply cylinder 211 to the corresponding cutting area assembly 100. The liquid supply pump 212 provides the cutting area with cutting liquid for cooling and lubrication. The liquid supply pump 212 extracts the cutting liquid from the cutting liquid supply cylinder 211 and distributes it to the corresponding cutting area through the pipeline. A liquid collecting port is provided at the bottom of each cutting area. The cutting liquid recovered by the liquid collecting port is then collected into the cutting liquid supply cylinder 211 through the pipeline to realize the recycling of the cutting liquid. The cutting liquid supply cylinder 211 is also provided with a liquid extraction pipe assembly, and the diaphragm pump extracts the waste liquid used for cutting through the liquid extraction pipe assembly. A limit buffer seat is also provided on one side of the cutting liquid supply cylinder 211 to prevent the component from colliding with other equipment during the pushing and pulling process.

[0050] Furthermore, the centralized cooling component includes a coolant heat exchange component 230 for cooling the slicer equipment and a cutting fluid heat exchange component 220 for cooling the cutting fluid. During the cutting process, the equipment is cooled by the coolant circulating in the coolant heat exchange component 230, and the cutting surface of the hard and brittle material is cooled by the cutting fluid circulating in the cutting fluid heat exchange component 220. The two work together to respectively realize the cutting process within the normal temperature range, thereby avoiding the reduction of cutting quality caused by overheating of the equipment or overheating of the material.

[0051] Furthermore, the coolant heat exchange component 230 includes a coolant water tank 231 for storing coolant, a coolant pump 233 for pumping coolant, and a coolant heat exchanger 232 for cooling the coolant. The coolant flowing through each cutting area assembly 100 device is cooled by the coolant heat exchanger 232 and then flows back to the coolant water tank 231. The centralized cooling component also includes a centralized cooling pipe and a centralized return pipe. The coolant stored in the coolant water tank 231 is transported to each device of the slicer through the centralized cooling pipe to cool each device. The used coolant is then returned to the coolant water tank 231 through the centralized return pipe. The coolant heat exchanger 232 exchanges heat with the coolant in the coolant water tank 231. The corresponding heat exchange component is provided with a factory cooling water circulation pipeline, and a coolant inlet and a coolant outlet are provided on one side of the coolant heat exchanger 232. The low-temperature cooling water enters the centralized cooling component from the factory cooling water inlet, and is used to cool the cutting liquid heat exchanger 224 and the coolant heat exchanger 232. The used factory cooling water flows out from the coolant outlet and returns to the factory cooling water large circulation. A temperature monitoring device is provided at the factory cooling water inlet to monitor in real time whether the factory cooling water inlet is cooling water of the required temperature.

[0052] Furthermore, the coolant pump 233 and the coolant heat exchanger 232 are both arranged above the coolant tank 231. The space of the integrated heat exchange assembly is fully utilized, and the coolant heat exchanger 232 is arranged above the coolant tank 231, so as to timely cool down the coolant in the coolant tank 231, and at the same time avoid the setting of long pipelines, reduce the risk of pipeline leakage, and facilitate equipment maintenance.

[0053] Furthermore, the cutting liquid heat exchange component 220 includes a filter barrel 223 for filtering and pumping the cutting liquid and a cutting liquid heat exchanger 224 for cooling the cutting liquid. The cutting liquid is first filtered by the filter barrel 223 and then flows into the cutting liquid heat exchanger 224 for cooling, and then transported to the corresponding cutting area. The filter barrel 223 is connected to the cutting liquid supply cylinder 211 through a pipeline. The cutting liquid supply cylinder 211 outputs the cutting liquid to the filter barrel 223 through the liquid supply pump 212 to filter out the particulate impurities. Then, after passing through the integrated heat exchange component, the cutting liquid passes through the flow monitoring component preset on the pipeline in front of the cutting liquid supply port 221 at a set temperature, and then outputs a preset specific flow through the mass flow meter 222 in the flow monitoring component, and finally reaches the cutting area assembly 100 through the cutting liquid supply port 221 to cool the hard and brittle material being cut. When the equipment is running, the cutting liquid first returns to the cutting liquid supply cylinder through the mass flow meter 222, and does not enter the cutting chamber 111, so that the flow rate of the cutting liquid is quickly increased, saving time. The filter barrel 223 includes at least one filter barrel 223 and a drain clamp valve disposed at the bottom of each filter barrel 223. The filter barrel 223 is fixed on the bottom crossbeam 440, and the bottom crossbeam 440 is fixed to the integrated heat exchange assembly. The drain clamp valve is a ball valve. After the equipment is cut once, the ball valve is opened to discharge the liquid inside the filter barrel 223. The cutting liquid must pass through the pressure detection device before entering the filter barrel 223 after being output by the liquid supply pump 212 to monitor the pressure of the filter barrel 223 in real time to prevent blockage.

[0054] Furthermore, each cutting area assembly 100 is physically connected through the same connection structure, and the liquid circuit assembly 200 is connected to each cutting area assembly 100 as a whole through the connection structure. The liquid circuit assembly 200 is rigidly connected to each cutting area assembly 100 through physical connection, which facilitates the movement and lifting of the whole machine, and ensures the stability of the internal connection of the equipment, avoiding the phenomenon of interface breakage during transportation, etc. At the same time, the connection structure is suitable for pre-installation work, reducing the technical requirements of on-site installation personnel.

[0055] Furthermore, each cutting area assembly 100 is detachably connected to the connection structure, and the connection structure is provided with connection sites for connecting each cutting area assembly 100, and the connection structure is also provided with reserved connection sites for connecting more cutting area assemblies 100. The user can fix the required number of cutting area assemblies 100 on the connection structure according to actual needs, and the connection sites are provided with reserved pipelines corresponding to the liquid circuit assembly 200, and the reserved pipelines are provided with reserved valves for opening and closing the connection between the cutting area assembly 100 and the liquid circuit assembly 200 at the connection sites, and the reserved valves can be used to limit the number of existing cutting area assemblies 100 in use, saving resources.

[0056] Furthermore, the connection structure is a connecting beam or a connecting frame. Furthermore, the connection structure is a connecting beam, and the two cutting area assemblies 100 are arranged symmetrically on both sides of the connecting beam. By connecting the two cutting area assemblies 100 to the cutting liquid supply assembly 210, the cutting liquid heat exchange assembly 220 and the coolant heat exchange assembly 230 arranged in the same area, each cutting area assembly 100 can obtain the cutting liquid and coolant required for cutting from a cutting liquid supply assembly 210, a cutting liquid heat exchange assembly 220, and a coolant heat exchange assembly 230, thereby achieving the dual-station goal of the slicer equipment. The plant space occupied by the dual-station slicer is smaller than the whole equipment space of the original slicer, thereby achieving the doubling of production capacity by directly replacing equipment without changing the plant area. The symmetrical arrangement is conducive to the effective management of the cutting area assembly 100 with a regular arrangement, which is convenient for enterprise management, and at the same time optimizes the use of plant space, with the least land and equipment cost investment, and the most efficient increase in production capacity per unit area. Further, the connecting crossbeam includes a top crossbeam 410, and top connection seats 420 for connecting the two cutting area assemblies 100 are arranged on both sides of the top crossbeam 410. Further, an electrical connection seat 430 for fixing the electrical assembly is also arranged on the top crossbeam 410, and the electrical assembly includes an electrical control cabinet 310 centrally arranged on one side or an electrical control cabinet 310 respectively arranged on both sides based on the two cutting area assemblies 100, and the electrical control cabinet 310 is fixedly connected to the electrical connection seat 430. Each cutting area assembly 100 is equipped with a set of electrical assemblies, and the two sets of electrical assemblies can be respectively provided with electrical control cabinets 310 for protection and distinction, or can be placed in one electrical control cabinet 310 for integrated operation. The layout of two electrical control cabinets 310 arranged between the two cutting area assemblies 100 is as follows: the two electrical control cabinets 310 are both fixed on the connection structure, respectively located on both sides of the connection structure, one of the electrical control cabinets 310 is arranged on the top of the centralized cooling component, and the other electrical control cabinet 310 is arranged on the top of the oil and gas assembly. The layout of an electric control cabinet 310 is as follows: the electric control cabinet 310 is fixed on one side of the connection structure, and the cutting liquid supply assembly 210, the cutting liquid heat exchange assembly 220, the coolant heat exchange assembly 230 and the oil and gas assembly are all arranged on the other side of the electric control cabinet 310. An operation box 320 is also arranged on each cutting area assembly 100, and the operation box 320 is connected to the electrical assembly signal in the electric control cabinet 310 to provide a human-machine interface and signal input for the electric control cabinet 310, so as to facilitate the operator to set the cutting process. Furthermore, the connecting beam includes a bottom beam 440, and the bottom beam 440 is provided with a bottom connecting seat 450 at both ends for connecting the two cutting area assemblies 100.

[0057] Furthermore, the cutting zone assembly 100 includes a protection mechanism and a feeding mechanism and a wire saw mechanism located inside the protection mechanism.

[0058] The wire saw mechanism includes a support frame 110, a main roller shaft 120 for supporting the cutting wire to form a cutting position, a wire winding assembly for retracting and releasing the cutting wire, and a steering wheel assembly for guiding the cutting wire to reciprocate between the main roller shaft 120 and the wire winding assembly. The support frame 110 includes a cutting chamber 111 and a winding chamber 112. The wire winding assembly is fixed in the winding chamber 112, the main roller shaft 120 is fixed in the cutting chamber 111, and the winding chamber 112 is arranged below the cutting chamber 111. By separating the support frame 110 into the cutting chamber 111 and the winding chamber 112 from top to bottom, the debris generated during the cutting process in the cutting chamber 111 is prevented from cutting the cutting wire in the winding chamber 112, thereby ensuring the safety of the cutting wire. At the same time, the arrangement of the upper and lower structures occupies a small area, so that the enterprise can add more wire saw equipment under the same land area conditions, thereby improving the production efficiency per unit area.

[0059] Furthermore, the steering wheel assembly includes a winding wire steering wheel 130, a tension steering wheel 150 and a main roller steering wheel 140, and the cutting wire is sequentially passed through the winding wire steering wheel 130, the tension steering wheel 150 and the main roller steering wheel 140 from the winding wire assembly to reach the main roller 120. The wire steering wheel 130, the tension steering wheel 150 and the main roller steering wheel 140 are symmetrically distributed on both sides of the main roller 120 with the main roller 120 as the symmetry axis, ensuring that the cutting wire can reciprocate along the same path on both sides of the main roller 120, and ensuring the stability of the cutting wire on the main roller 120.

[0060] Furthermore, the tension steering wheel 150 is arranged above the winding wire steering wheel 130, and the main roller steering wheel 140 is arranged above the tension steering wheel 150. The main shaft of the tension steering wheel 150 is arranged above the main shaft of the winding wire steering wheel 130, and the main shaft of the main roller steering wheel 140 is arranged above the main shaft of the tension steering wheel 150, so as to avoid the cutting lines between different guide wheels from interfering with each other.

[0061] Furthermore, the wheel surface of the tension steering wheel 150 is coplanar with the wheel surface of the winding wire steering wheel 130. The coplanar structure is conducive to preventing the cutting wire from curling between the two wheels. Furthermore, the lowest point of the tension steering wheel 150 and the highest point of the winding wire steering wheel 130 are located on the same horizontal line, which can ensure that the cutting wire participates in cutting with the shortest distance, reducing the probability of the cutting wire breaking during the process of winding and releasing the wire.

[0062] Furthermore, the tension steering wheel 150 is arranged at the junction of the cutting chamber 111 and the winding chamber 112. The tension steering wheel 150 is arranged at the junction of the cutting chamber 111 and the winding chamber 112 to ensure that the tension steering wheel 150 is arranged between the main roller shaft 120 and the winding wire assembly, and cooperates with the main roller shaft steering wheel 140 and the winding wire steering wheel 130 arranged on both sides of the tension steering wheel 150 to achieve the dual functions of guiding and adjusting tension.

[0063] Furthermore, the tension steering wheel 150 is arranged on the outside of the support frame 110 along the axial direction of the main roller shaft 120, and the corresponding support frame 110 is provided with a through hole 113 for the cutting line to pass through the cutting chamber 111 and the winding chamber 112. The tension steering wheel 150 is arranged on the outside of the support frame 110, which is simple and convenient to set up, and avoids the tensioning component connected to the tension steering wheel 150 from interfering with the winding wire component or the main roller shaft 120 inside the support frame 110. Correspondingly, a through hole 113 is opened on the support frame 110, and the through hole 113 includes but is not limited to a through hole or a notch, so that the cutting line reciprocates inside the support frame 110 after passing through the through hole 113, and will not interfere with the protective cover 160 provided outside the support frame 110, which is conducive to protecting the cutting line and avoiding the situation where the cutting line is damaged by external force.

[0064] Furthermore, two through holes 113 are provided corresponding to the upper and lower edges of the tension steering wheel 150, and the two through holes 113 lead to the cutting chamber 111 and the winding chamber 112 respectively. The through holes 113 are provided corresponding to the cutting chamber 111 and the winding chamber 112 respectively, so as not to destroy the mutual independence of the two compartments. At the same time, the separated through holes 113 limit the cutting wires, so as to avoid the cutting wires from being entangled with each other when unexpected situations such as wire breakage occur.

[0065] Furthermore, the highest point of the inner wall of the through hole 113 is higher than the highest point of the tension steering wheel 150, and the lowest point of the inner wall of the through hole 113 is lower than the lowest point of the tension steering wheel 150. The swing amplitude of the tension steering wheel 150 is limited, so the highest point of the through hole 113 is set higher than the highest point of the tension steering wheel 150, and the lowest point is set lower than the lowest point of the tension steering wheel 150, so as to ensure that the cutting line is not affected by the limit of the through hole 113 during the adjustment of the tensioning assembly, and avoid the cutting line from being worn on the through hole 113 and affecting the cutting quality.

[0066] Furthermore, it includes a tensioning assembly fixed on the outer wall of the support frame 110, the tensioning assembly includes a tension motor 151 and a tension arm 152, the tension steering wheel 150 is fixedly connected to the output shaft of the tension motor 151 through the tension arm 152, the tension motor 151 is fixed to the support frame 110 through the tension motor seat 153, and the tension motor seat 153 is provided with a limit rod 154 for limiting the swing amplitude of the tension arm 152.

The free end of the tension arm 152 is connected to the central axis of the tension steering wheel 150. Through the rotation of the output shaft of the tension motor 151, the tension arm 152 is driven to make a circular motion around the output shaft, thereby driving the tension steering wheel 150 fixed on the tension arm 152 to move forward and backward relative to the support frame 110, so as to achieve the purpose of increasing or reducing the tension of the cutting line. Two limit rods 154 are arranged in parallel, and the length of the limit rods 154 is greater than the distance from the tension arm 152 to the tension motor seat 153, so as to ensure that the tension arm 152 is always in the swing inside the two limit rods 154, which is convenient for the installation process of the cutting line, and ensure that the tension steering wheel 150 is always between the main roller shaft steering wheel 140 and the winding wire steering wheel 130, while avoiding damage to the cutting line caused by excessive swinging.

[0067] Furthermore, the main roller steering wheel 140 is arranged in the cutting chamber 111.

[0068] Furthermore, the wheel surface of the main roller steering wheel 140 is tilted toward the main roller 120 side, so that the cutting line is guided from the tension steering wheel 150 to the main roller 120. The main roller steering wheel 140 is tilted relative to the horizontal plane, so as to ensure that the main roller steering wheel 140 can be set on both sides of the main roller 120 instead of directly below it, thereby ensuring that the cutting line wound on the main roller steering wheel 140 is protected from the impact of debris falling during the cutting process. The wheel surface of the main roller steering wheel 140 is vertically arranged relative to the wheel surface of the tension steering wheel 150, and the tension steering wheel 150 is in a vertical state.

The adjustment seat 141 includes an adjustment base and an adjustment rod. The bottom end of the adjustment rod is rotatably connected relative to the adjustment base, and the top end of the adjustment rod fixes the central axis of the main roller steering wheel 140. The adjustment rod is rotated according to the height of the main roller 120 to make the wheel surface of the main roller steering wheel 140 tangent to the main roller 120, thereby reducing unnecessary friction of the cutting line on the main roller steering wheel 140 and the main roller 120, and reducing the wear of the cutting line.

[0070] Furthermore, the bottom of the adjustment seat 141 is fixed in the cutting chamber 111 through the sliding assembly 142.

Slide rails are provided on the edges of both sides of the cutting chamber 111 along the axis of the main roller 120, and sliders are fixed to the bottom of the adjustment seat 141 corresponding to the slide rails. The sliders slide on the slide rails to drive the adjustment seat 141 to move back and forth in the cutting chamber 111, so as to facilitate the adjustment of the number of windings of the cutting wire on the main roller 120, and also facilitate the adjustment of the cutting wire from the main roller steering wheel 140 to the wire slot on the main roller 120 with the shortest distance, so as to avoid the cutting wire from being worn on the wheel frame of the main roller steering wheel 140 or the groove edge of the wire slot.
