Description

Technical Field

[0001] This invention relates to the field of crystal rod cutting, and in particular to a clamping device for a slicing machine, a crystal rod conveying structure, and a slicing machine. Background Technology

[0002] Some of the slicing machines produced by the applicant have loading and unloading ports on both the front and rear sides, allowing the crystal rods to be transported from both sides of the slicing machine. During this process, the crystal rods need to move on a clamping device, and under the guidance of the clamping device, they move from the loading and unloading ports into the cutting chamber, where they are then clamped by the clamping device.

[0003] Correspondingly, the movement of the crystal tray on the clamping device needs to be limited to ensure accurate entry into the cutting chamber. The crystal tray may enter the cutting chamber from the front or rear of the clamping device. Taking the crystal tray moving backward from the front of the clamping device as an example, a limiting structure is set at the rear of the clamping device. After the crystal tray enters the cutting chamber, it contacts the limiting structure and acts as a limit, allowing the crystal ingot to be cut normally. However, when the crystal tray moves forward from the rear of the clamping device, the limiting structure directly blocks the crystal tray, preventing it from entering the cutting chamber. Therefore, the existing mechanical limiting structure is insufficient to meet the requirements of bidirectional feeding of the crystal tray.

[0004] For the reasons stated above, at present, the applicant can only install sensors on the clamping device to electrically control the movement of the crystal tray in the actual production process. However, as is well known, the sensors have low accuracy in sensing the position of the crystal tray, so the electronic control method is not effective in limiting the position of the crystal tray, which affects the cutting effect of the crystal rod. Summary of the Invention

[0005] Therefore, it is necessary to provide a clamping device, a crystal rod conveying structure, and a slicing machine to address the problem that the clamping device cannot mechanically limit the crystal rod without affecting its entry into the cutting chamber.

[0006] A clamping device for a slicer includes a clamping base and at least two limiting members, wherein the limiting members are movably disposed on the clamping base;

[0007] The outer wall of the clamping seat is provided with a receiving groove, and the limiting member has an avoidance state and a limiting state;

[0008] When the limiting member is in the avoidance state, the limiting member is at least partially housed in the receiving groove so as to avoid the crystal tray during the movement of the crystal tray;

[0009] When the limiting member is in the limiting state, the limiting member at least partially protrudes from the outer wall edge of the clamping seat to abut against the crystal holder;

[0010] The two limiting members are a first limiting member and a second limiting member, which are spaced apart along the length of the clamping seat.

[0011] The limiting member of the present invention has a hinged end and a free end. The hinged end is hinged to the inner wall of the receiving groove, and a torsion spring is sleeved on the hinged end. The two ends of the torsion spring are respectively positioned on the inner wall of the receiving groove and the free end.

[0012] The inner wall of the receiving groove of the present invention is provided with a locking part. When the limiting member is in the avoidance state, the free end is locked at the locking part.

[0013] When the limiting member is in the avoidance state, the limiting member abuts against the inner wall of the receiving groove. Alternatively, a blocking member is fixed on the inner wall of the receiving groove, and when the limiting member is in the avoidance state, the limiting member abuts against the blocking member.

[0014] The clamping base of the present invention is provided with a first proximity switch for detecting the distance to the free end of the first limiting member and a second proximity switch for detecting the distance to the free end of the second limiting member. Both the first proximity switch and the second proximity switch are electrically connected to a control board. The control board is electrically connected to an alarm. When both the first proximity switch and the second proximity switch detect the free end or neither detects the free end, the control board controls the alarm to sound an alarm.

[0015] The limiting member of the present invention has a free end and a positioning end. The positioning end is fixed on the inner wall of the receiving groove, and the free end moves in and out of the receiving groove so that the limiting member can switch between an avoidance state and a limiting state.

[0016] The limiting component of the present invention includes a limiting block and a return spring. One end of the return spring is a positioning end, and the other end of the return spring is disposed on the limiting block so that the limiting block serves as the free end.

[0017] The inner wall of the receiving groove of the present invention is provided with a locking part. When the limiting member is in the avoidance state, the limiting block is locked at the locking part.

[0018] The outer wall of the limiting block of the present invention is in contact with the inner wall of the receiving groove so as to guide the movement of the limiting block through the inner wall of the receiving groove.

[0019] The limiting component of the present invention is a telescopic tube, one end of which is a free end and the other end of which is a positioning end.

[0020] The inner wall of the receiving groove of the present invention is provided with a first detection switch and a second detection switch. The first detection switch detects the status of the first limiting member, and the second detection switch detects the status of the second limiting member. Both the first detection switch and the second detection switch are electrically connected to a control board, and the control board is electrically connected to an alarm. When the first detection switch and the second detection switch detect that both the first limiting member and the second limiting member are in an avoidance state or both are in a limiting state, the control board controls the alarm to sound an alarm.

[0021] The clamping base of the present invention is equipped with an electric device, and the limiting member is installed on the electric device. The electric device controls the limiting member to switch between an avoidance state and a limiting state.

[0022] The clamping base of the present invention is equipped with a lifting cylinder for supporting the crystal tray, and a third proximity switch is provided on the bottom wall of the clamping base. The third proximity switch is used to detect the distance between the crystal tray and the bottom wall of the clamping base.

[0023] The clamping device of the present invention further includes a connecting plate, the top edge of which is fixed to the bottom edge of the clamping seat, and the bottom edge of which extends laterally to form a sliding plate. A roller is rotatably mounted on the sliding plate, and the sliding plate is located on the side of the connecting plate close to the clamping seat.

[0024] A crystal rod conveying structure includes a clamping device and a crystal holder, wherein the crystal holder is movably disposed at the bottom of the clamping base along the length direction of the clamping base.

[0025] A slicing machine includes a cutting cabinet and a crystal rod conveying structure, wherein the cutting cabinet has material inlets on the front and rear sides for the crystal rod to enter and exit the cutting cabinet.

[0026] The beneficial effects of this invention are as follows:

[0027] Taking the case where the first limiting member is located at the front end of the clamping seat and the second limiting member is located at the rear end of the clamping seat as an example, the crystal tray can move forward from the rear end of the clamping seat into the cutting chamber. During this process, the second limiting member is in a avoidance state, and the crystal tray will not be obstructed until the crystal tray collides with the first limiting member in the limiting state, thereby achieving the avoidance effect of the limiting member on the crystal tray. However, if the crystal tray moves backward from the front end of the clamping seat, at least a part of the first limiting member can be controlled to enter the receiving groove to achieve an avoidance state, thereby allowing the first limiting member to avoid the crystal tray and avoid obstructing the movement of the crystal tray. This allows the crystal tray to pass over the first limiting member and enter the cutting chamber until it collides with the second limiting member in the limiting state, where the second limiting member limits the crystal tray. By switching between the avoidance state and the limiting state by the limiting component, it can be ensured that the crystal tray can smoothly enter the cutting chamber regardless of whether it moves from front to back or from back to front on the clamping seat. The limiting component also provides a mechanical limiting effect on the crystal tray in one of the moving directions, thereby improving the positioning accuracy of the crystal tray and ensuring the cutting quality of the crystal rod.

[0048] Example 1:

[0049] See Figure 1 This embodiment provides a crystal rod conveying structure, including a clamping device 1 and a crystal holder 2. Both the crystal holder 2 and the clamping device 1 are elongated. The crystal holder 2 is located at the bottom of the clamping device 1 and can move back and forth along the axial direction of the clamping device 1, i.e., the length direction.

[0050] See Figure 3-5Specifically, the clamping device 1 includes a clamping base 11 and a limiting member, wherein the limiting member is movably disposed on the clamping base 11. A receiving groove is provided on the outer wall of the clamping base 11, through which the limiting member switches between a clearance state and a limiting state. When the limiting member is in the clearance state, it is at least partially housed within the receiving groove; when the limiting member is in the limiting state, it protrudes at least partially from the outer wall edge of the clamping base 11. Here, the outer wall of the clamping base 11 can be a side wall, a top wall, or a bottom wall.

[0051] In this embodiment, there are multiple limiting members, two of which are the first limiting member 12 and the second limiting member 13. There are also multiple receiving slots, two of which are the first receiving slot 111 and the second receiving slot 112. The first limiting member 12 is movably disposed at the first receiving slot 111, and the second limiting member 13 is movably disposed at the second receiving slot 112.

[0052] The first receiving groove 111 and the second receiving groove 112 can be located simultaneously on the left side wall of the clamping seat 11, or simultaneously on the right side wall of the clamping seat 11, or respectively on the left and right side walls of the clamping seat 11. That is, the relative position of the first receiving groove 111 and the second receiving groove 112 in the width direction of the clamping seat 11 is not limited. However, the first receiving groove 111 and the second receiving groove 112 are distributed at intervals along the length direction of the clamping seat 11. Taking this embodiment as an example, the left side wall of the clamping seat 11 is provided with the first receiving groove 111 and the second receiving groove 112, and the right side wall of the clamping seat 11 is also provided with the first receiving groove 111 and the second receiving groove 112. Both first receiving grooves 111 are close to the front end of the clamping seat 11, and both second receiving grooves 112 are close to the rear end of the clamping seat 11. Therefore, the first receiving groove 111 is located in front of the second receiving groove 112. Correspondingly, the first limiting member 12 is located in front of the second limiting member 13. The first limiting member 12 and the second limiting member 13 are distributed at intervals along the length direction of the clamping seat 11. Since the clamping seat 11 has a symmetrical structure, this embodiment will be described in the following description using the first receiving groove 111 and the second receiving groove 112 on the right side wall of the clamping seat 11.

[0053] In some other embodiments, there may be only one receiving groove on the right side wall of the clamping seat 11, and the first limiting member 12 and the second limiting member 13 are both located in the receiving groove. Therefore, the number of limiting members may be greater than the number of receiving grooves, and a single receiving groove can accommodate multiple limiting members.

[0054] In this embodiment, the limiting member has a hinged end and a free end. For easy distinction, the following names are used in this embodiment: the hinged end of the first limiting member 12 is the first hinged end 121, the free end of the first limiting member 12 is the first free end 122, the hinged end of the second limiting member 13 is the second hinged end 131, and the free end of the second limiting member 13 is the second free end 132.

[0055] The first hinge end 121 is hinged to the inner wall of the first receiving groove 111, so the portion of the first limiting member 12 at the first hinge end 121 is located within the first receiving groove 111. The first receiving groove 111 extends to the bottom wall of the clamping seat 11 to form a first clearance opening 1111. The first clearance opening 1111 provides the first limiting member 12 with a space for vertical rotation, so that the first free end 122 can enter and exit the first receiving groove 111 through the first clearance opening 1111.

[0056] Similarly, the second hinge end 131 is hinged to the inner wall of the second receiving groove 112, and the second receiving groove 112 extends to the bottom wall of the clamping seat 11 to form a second clearance opening 1121, so that the second free end 132 can enter and exit the second receiving groove 112 through the second clearance opening 1121.

[0057] The crystal holder 2 has a limiting rib 21 on its top right edge, which extends along the axial direction of the crystal holder 2. When the first free end 122 is located below the first clearance opening 1111, that is, a part of the first limiting member 12 protrudes from the side wall edge of the clamping seat 11, the first limiting member 12 is in a limiting state. At the same time, the second limiting member 13 is located in the second receiving groove 112, that is, the second limiting member 13 is in a clearance state. This allows the front end of the first free end 122 and the limiting rib 21 to be opposite each other along the axial direction of the crystal holder 2. Meanwhile, the second limiting member 13 will not be opposite to the end of the limiting rib 21 in the axial direction of the crystal holder 2. Therefore, the crystal holder 2 can slide forward from the rear end of the clamping seat 11 to feed material, passing the second limiting member 13 until it collides and is limited by the first free end 122.

[0058] Similarly, in other embodiments, when the first limiting member 12 is located in the first receiving groove 111, that is, when the first limiting member 12 is in the avoidance state, and the second free end 132 is located below the second avoidance opening 1121, that is, when a part of the second limiting member 13 protrudes from the side wall edge of the clamping seat 11 and is in the limiting state, the crystal holder 2 can move from front to back on the clamping seat 11, and the rear end of the limiting rib 21 passes over the first limiting member 12 until it collides with and is limited by the second hinge end 131.

[0059] Therefore, in this embodiment, by rotating the first limiting member 12 and the second limiting member 13, only one of the first free end 122 and the second free end 132 is opposite to the end of the limiting rib 21. No matter whether the crystal holder 2 moves from front to back or from back to front, the first limiting member 12 and the second limiting member 13 will not obstruct the crystal holder 2 from entering the cutting chamber. The first limiting member 12 and the second limiting member 13 also realize the mechanical limiting of the crystal holder 2 in two directions, so that the crystal holder 2 obtains better limiting accuracy in the cutting chamber, thereby ensuring the cutting quality of the crystal rod.

[0060] It is conceivable that in other embodiments, the first limiting member 12 can be movably disposed in the first receiving groove 111 in a vertically movable manner, and the second limiting member 13 can be movably disposed in the second receiving groove 112 in a vertically movable manner, so that a part of the first limiting member 12 enters and exits the first receiving groove 111 through the first clearance port 1111, and a part of the second limiting member 13 enters and exits the second receiving groove 112 through the second clearance port 1121, which can also meet the limiting requirements of the crystal holder 2 in two directions in this embodiment.

[0061] In this preferred embodiment, a torsion spring is fitted onto the hinge end, with its two ends positioned on the inner wall of the receiving groove and the free end, respectively. For ease of distinction, the torsion spring fitted onto the first hinge end 121 is designated as the first torsion spring 1211, and the torsion spring fitted onto the second hinge end 131 is designated as the second torsion spring.

[0062] The two ends of the first torsion spring 1211 are respectively positioned on the inner wall of the first receiving groove 111 and the first free end 122. The first torsion spring 1211 provides the first free end 122 with a tendency to rotate downwards towards the first clearance opening 1111. Since the first limiting member 12 also has a tendency to rotate downwards towards the first clearance opening 1111 under its own gravity, the first free end 122 can move away from the first receiving groove 111 to the maximum extent under the dual action of gravity and the first torsion spring 1211, thereby effectively facing the front end of the limiting rib 21 and fully limiting the limiting rib 21.

[0063] Similarly, the two ends of the second torsion spring are respectively positioned on the inner wall of the second receiving groove 112 and the second free end 132. The second torsion spring provides the second free end 132 with a tendency to rotate downwards towards the second clearance opening 1121. Under the combined action of its own weight and the second torsion spring, the second free end 132 can move away from the second receiving groove 112 to the maximum extent, thus limiting the rear end of the limiting rib 21.

[0064] Correspondingly, when the first free end 122 rotates into the first receiving groove 111, it needs to overcome the elastic force of the first torsion spring 1211 and the gravity of the first limiting member 12. If the first limiting member 12 needs to be stably stationed in the first receiving groove 111 to avoid the limiting rib 21, then the first limiting member 12 needs to be locked in the first receiving groove 111. In this embodiment, a locking part is provided on the inner wall of the first receiving groove 111. The locking part can be a hole or other common locking structure. For example, in this embodiment, the locking part is the first locking hole 1112. By rotating the first free end 122 upward so that the first limiting member 12 is fully inserted into the first receiving groove 111, and the first free end 122 is located at the first locking hole 1112, the first free end 122 can be locked in the first receiving groove 111 by screws. If the second free end 132 is located below the second clearance opening 1121, then the crystal holder 2 can be fed from front to back, and the second free end 132 can limit the crystal holder 2.

[0065] Similarly, a locking part, which is a second locking hole, is also provided on the inner wall of the second receiving groove 112. When the second free end 132 rotates to the second locking hole, it is locked by a screw, at which time the second limiting member 13 is located inside the second receiving groove 112. If the first free end 122 is located below the first receiving groove 111, then the crystal tray 2 can be fed from back to front, and limited by the first free end 122.

[0066] Taking the first torsion spring 1211 as an example, it can be understood that in some other embodiments, if the elastic force of the first torsion spring 1211 provides a tendency for the first free end 122 to rotate into the first receiving groove 111, then when the first free end 122 is located below the first receiving groove 111, the first limiting member 12 needs to be locked. The first free end 122 located outside the first receiving groove 111 cannot be used as the locking position. Only the part of the first limiting member 12 near the first hinge end 121 (the part located inside the first receiving groove 111) can be locked on the inner wall of the first receiving groove 111 by screws. Since the locking position is close to the first hinge end 121 and the lever arm is short, the locking force of the screw is required to be higher.

[0067] If the crystal holder 2 collides with the first free end 122 or the second free end 132 during the feeding process, the crystal holder 2 will sense the resistance and the control board will control the crystal holder 2 to stop moving.

[0068] As described above, if the first free end 122 is located in the first receiving groove 111 and the second free end 132 is located in the second receiving groove 112, then the crystal tray 2 can be fed from front to back or from back to front, but it cannot be stopped. However, if the first free end 122 is located below the first receiving groove 111 and the second free end 132 is located below the second receiving groove 112, then the crystal tray 2 will be stopped by the first free end 122 when fed from front to back, but not by the second free end 132. Similarly, the crystal tray 2 will be stopped by the second free end 132 when fed from back to front, but not by the first free end 122. In either case, the crystal tray 2 cannot reach the part of the clamping seat 11 located between the first free end 122 and the second free end 132, and therefore cannot enter the cutting chamber. Therefore, when the first free end 122 is located below the first receiving groove 111, the second free end 132 must be located inside the second receiving groove 112, and when the first free end 122 is located inside the first receiving groove 111, the second free end 132 must be located below the second receiving groove 112.

[0069] Based on this, in this embodiment, a first proximity switch 1221 for detecting the first free end 122 is provided on the inner wall of the first receiving groove 111. When the first free end 122 rotates, the distance between it and the first proximity switch 1221 changes. When the first proximity switch 1221 detects the first free end 122, it indicates that the first free end 122 is located inside the first receiving groove 111. If the first proximity switch 1221 does not detect the first free end 122, it indicates that the first free end 122 is located below the first receiving groove 111. Similarly, a second proximity switch 1321 for detecting the second free end 132 is provided on the inner wall of the second receiving groove 112.

[0070] The first proximity switch 1221 and the second proximity switch 1321 are both electrically connected to the control board, which is electrically connected to an alarm. If both proximity switches 1221 and 1321 detect a signal simultaneously or neither detects a signal simultaneously, the control board can control the alarm to sound an alarm based on this condition. Conversely, if only one of the first proximity switches 1221 and 1321 detects a signal, the control board does not need to cause the alarm to sound an alarm.

[0071] Preferably, in order to facilitate the alignment and locking of the first free end 122 and the first locking hole 1112, and the alignment and locking of the second free end 132 and the second locking hole, in this embodiment, when the first free end 122 is located at the first locking hole 1112, the first limiting member 12 abuts against the inner wall of the first receiving groove 111, and when the second free end 132 is located at the second locking hole, the second limiting member 13 abuts against the inner wall of the second receiving groove 112.

[0072] As an alternative to aligning the first free end 122 and the first locking hole 1112 and aligning the second free end 132 and the second locking hole in this embodiment, a first blocking member can also be provided on the inner wall of the first receiving groove 111. When the first free end 122 is located at the first locking hole 1112, the first limiting member 12 abuts against the first blocking member. A second blocking member is provided on the inner wall of the second receiving groove 112. When the second free end 132 is located at the second locking hole, the second limiting member 13 abuts against the second blocking member.

[0073] See Figure 3 In this embodiment, the top of the clamping seat 11 is provided with a cylinder groove 113, and a lifting cylinder is installed in the cylinder groove 113. The lifting cylinder can be a pneumatic cylinder or a hydraulic cylinder. See also Figure 8-9 The top of the crystal holder 2 is a lifting step 22. The power output end of the lifting cylinder is located below the lifting step 22, thereby lifting the entire crystal holder 2 through the lifting step 22.

[0074] See Figure 2 , 6 7 and 10, the clamping device 1 also includes a connecting plate 14, the top edge of which is fixed to the bottom wall edge of the clamping seat 11, and the bottom edge of which extends laterally to form a sliding plate 141. A roller 1411 is rotatably mounted on the sliding plate 141, and the sliding plate 141 is located on the side of the connecting plate 14 near the clamping seat 11. The edge of the crystal tray 2 is provided with a groove 23, and the roller 1411 is located in the groove 23.

[0075] When the crystal holder 2 moves on the clamping seat 11, the lifting cylinder can lower the crystal holder 2, so that the top wall of the slide groove 23 contacts the top of the roller 1411. The roller 1411 can then lift the crystal holder 2. When the crystal holder 2 moves, part of the sliding friction between the lifting cylinder and the lifting step 22 is converted into rolling friction between the top wall of the slide groove 23 and the roller 1411, thereby reducing the resistance to the movement of the crystal holder 2. When the crystal holder 2 moves axially into position, the lifting cylinder can further lift the crystal holder 2, so that the top wall of the slide groove 23 separates from the roller 1411, until the bottom wall of the slide groove 23 contacts the roller 1411, thereby clamping the clamping seat 11 and the crystal holder 2 in the vertical direction, so as to achieve the purpose of stable cutting of the crystal rod in the cutting chamber.

[0076] Preferably, a third proximity switch is provided on the bottom wall of the clamping seat 11. The third proximity switch is used to detect the distance between the crystal holder 2 and the bottom wall of the clamping seat 11 to confirm whether the crystal holder 2 and the clamping seat 11 are in a clamped state in the vertical direction.

[0077] Furthermore, a limiting groove 24 is provided on the top of the crystal holder 2, and a limiting strip 15 is provided on the bottom wall of the clamping seat 11. When the crystal holder 2 and the clamping seat 11 are clamped together in the vertical direction, the limiting strip 15 is located in the limiting groove 24, thereby positioning the crystal holder 2 in the width direction, thereby further stabilizing the position of the crystal holder 2 during the crystal rod cutting process.

[0078] Since both the first receiving groove 111 and the second receiving groove 112 have side openings, the sides of the first receiving groove 111 and the second receiving groove 112 are not obstructed by the connecting plate 14, thus ensuring the exposure of the first locking hole 1112 and the second locking hole, and therefore not affecting the locking of the first free end 122 and the second free end 132. However, since the connecting plate 14 is located directly below the first clearance opening 1111 and the second clearance opening 1121, in order to prevent the connecting plate 14 from obstructing the movement of the first free end 122 and the second free end 132 at the first clearance opening 1111 and the second clearance opening 1121, see [reference needed]. Figure 2 The sidewall of the connecting plate 14 is recessed to form a clearance notch 142 at the top edge of the connecting plate 14. The clearance notch 142 is located below the first clearance opening 1111 and the second receiving groove 112 to allow the first free end 122 and the second free end 132 to move.

[0079] Example 2:

[0080] Compared with Embodiment 1, this embodiment provides an additional working state of the limiting member. In this embodiment, the limiting member has a free end and a positioning end. The positioning end is fixed on the inner wall of the receiving groove, while the free end can move linearly relative to the positioning end, thereby entering and exiting the receiving groove, thus allowing the limiting member to switch between an avoidance state and a limiting state.

[0081] See Figure 11-12 In this embodiment, the limiting member includes a limiting block 16 and a return spring 17. The two ends of the return spring 17 are respectively mounted on the inner wall of the receiving groove and on the limiting block 16. At this time, the end of the return spring 17 mounted on the inner wall of the receiving groove is the positioning end, and the limiting block 16 serves as the free end of the limiting member. Under the action of the return spring 17, the limiting block 16 can only move along a straight line.

[0082] In this embodiment, the clamping base 11 is also provided with a first receiving groove 111 and a second receiving groove at the front and rear. Taking the first receiving groove 111 as an example, the limiting block 16 can fall down on its own under the combined action of the return spring 17 and its own weight, so that the bottom of the limiting block 16 is stably opposite to the end of the limiting rib 21, thereby putting the limiting member in a limiting state and playing a stable limiting role for the limiting rib 21. The inner wall of the first receiving groove 111 is provided with a locking part. By manually overcoming the return spring 17 and the limiting block 16, the limiting block 16 can be raised, so that the limiting member is in an avoidance state. At this time, the limiting block 16 is completely located in the first receiving groove 111. At the same time, locking the limiting block 16 at the locking part can make the limiting block 16 play a role in fully avoiding the limiting rib 21.

[0083] Preferably, a portion of the outer wall of the limiting block 16 is fitted against the inner wall of the first receiving groove 111, so that the movement of the limiting block 16 is guided by the inner wall of the first receiving groove 111, thereby reducing the deflection of the limiting block 16 during movement and providing more precise limiting of the limiting rib 21. Unlike Embodiment 1, when the limiting rib 21 impacts the limiting block 16, since the moving direction of the limiting block 16 is perpendicular to the moving direction of the limiting rib 21, the limiting block 16 will not move, thus providing a better limiting effect on the limiting rib 21.

[0084] In this embodiment, a first detection switch is provided on the inner wall of the first receiving groove 111, and a second detection switch is provided on the inner wall of the second receiving groove. The first detection switch detects the state of the first limiting member, and the second detection switch detects the state of the second limiting member. In this embodiment, the first and second detection switches can be proximity switches, micro switches, or other switches known in the art.

[0085] The first detection switch and the second detection switch are both electrically connected to the control board, which is electrically connected to an alarm. When the first detection switch and the second detection switch detect that both the first limiter and the second limiter are in an avoidance state or both are in a limit state, the control board controls the alarm to sound an alarm.

[0086] In some other embodiments, the limiting member is a telescopic tube, one end of which is a free end and the other end of which is a positioning end. The telescopic tube can extend under the action of gravity to be in a limiting state, and when the telescopic tube shortens, it is in an avoidance state.

[0087] Example 3:

[0088] The difference between this embodiment and embodiments 1 and 2 is that the movement of the limiting member does not depend on its own gravity or torsion springs or springs. Instead, an electric device is installed on the clamping seat, and the limiting member is installed on the electric device. The electric device controls the limiting member to move or rotate, thereby switching the limiting member between the avoidance state and the limiting state.

[0089] The electric device can be a motor or an electric telescopic rod, and those skilled in the art can choose according to specific practical needs and structural design.

[0090] Of course, since the state of the limiting component is controlled by the electric device, it is not easy to cause the limiting component to move when the limiting rib hits the limiting component, so as to improve the limiting effect of the limiting component. At the same time, the state of the limiting component can be directly monitored by the electric device, so there is no need to set up a first detection switch and a second detection switch.

[0091] Example 4:

[0092] This embodiment provides a slicing machine, including a cutting cabinet and a crystal rod conveying structure as described in Embodiments 1, 2, or 3. The cutting cabinet has a cutting chamber, and material inlets are provided on both the front and rear sides of the cutting cabinet, which are connected to the cutting chamber. The crystal rod can move from front to back on the clamping seat, thereby entering the cutting chamber from the material inlet on the front side of the cutting cabinet, or it can move from back to front, thereby entering the cutting chamber from the material inlet on the rear side of the cutting cabinet.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
