Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE This application relates to the field of material transportation, and more particularly to belt feeders. [Background technology]

[0002] Belts are widely used as a material transport carrier. When materials are fed to belts of different specifications, manual adjustment is required to prevent the belts from shifting. This operation is simple, highly repetitive, laborious, and time-consuming, which is not conducive to automation. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a belt feeding device that can automatically match belts of different specifications and regulate the position of the belt during transportation of the belt. [Means for solving the problem]

[0004] An embodiment of the present application provides a belt feeder. Two of the first, second and third directions are defined as being perpendicular to each other. The belt feeder includes a track assembly, a feed assembly and a limit assembly. The track assembly includes a first rail member and a second rail member. The first rail member is used to place the belt. The first rail member and the second rail member are arranged to face each other along the first direction and surround each other to form a transport path. The transport path extends along the second direction. The second rail member is movable along the first direction relative to the first rail member. The feed assembly includes a first driver and a first driver head. The first driver is fixedly arranged relative to the first rail member. The first driver head is provided on the first driver. The first driver can drive and move the first driver head. The first driver head is used to move the belt along the transport path. The limit assembly includes a second driver and a presser member. The second driver is fixedly arranged relative to the first rail member. The pressure member is provided on the first rail member. The second driver is capable of driving the pressure member to move in the third direction. The pressure member and the first rail member are used to abut on opposing sides of the belt along the third direction.

[0005] In the above embodiment, the first driver moves the belt in the transport path via the first driver head, thereby transporting the belt along the second direction. The second rail member is moved to change the distance of the transport path in the first direction so that belts of different lengths extend in the first direction, are restricted by the boundary of the transport path in the first direction, and are prevented from freely changing direction in the first direction while moving in the transport path. The second driver presses the belt against the first rail member along the third direction by driving the pressing member, thereby restricting the position of the belt in the third direction. The second driver changes the position of the pressing member in the third direction so that belts of different lengths extend in the third direction, are restricted by the cooperation of the pressing member and the first rail member in the third direction, and are prevented from freely changing direction in the third direction while moving in the transport path. Therefore, in two directions perpendicular to the belt transport direction, the belt feed device can effectively match belts of different specifications and maintain stable transportation of belts of different specifications.

[0006] In some embodiments of the present application, the first rail member includes a first stopper surface and a second stopper surface. The second rail member includes a third stopper surface and a fourth stopper surface. The first stopper surface and / or the second stopper surface are used to carry a belt. The first stopper surface and the third stopper surface are distributed along a third direction. The second stopper surface and the fourth stopper surface are distributed along a second direction. The first stopper surface, the second stopper surface, the third stopper surface and the fourth stopper surface are surrounded to form a transport path.

[0007] In the above embodiment, the first and third stopper surfaces limit the movement range of the belt in the third direction, and the second and fourth stopper surfaces limit the movement range of the belt in the first direction. This prevents the belt from freely changing direction in a direction perpendicular to the transport direction while moving through the transport path. When the belt is supported on the first and / or second stopper surfaces, the movement of the belt through the transport path is not affected when the third and fourth stopper surfaces move in accordance with the movement of the second rail member. Therefore, the transport of the belt through the transport path and the adjustment of the transport path in the first direction are performed simultaneously, improving production efficiency.

[0008] In some embodiments of the present application, the track assembly further includes a first fixed seat, a third driver, and a second driver head. The third driver is disposed on the first fixed seat. The second driver head is disposed on the third driver. The third driver drives the movement of the second driver head. The second driver head can move the second rail member along the first direction.

[0009] In the above embodiment, the third driver moves the second rail member via the second driver head with the first fixed seat as a reference, thereby realizing automatic adjustment of the transport path in the first direction.

[0010] In some embodiments of the present application, the track assembly further includes a first elastic member coupled to the second rail member and the first fixed seat, and the second driving head is abutted against the second rail member.

[0011] In the above embodiment, the first elastic member can apply an elastic force to the second rail member to reset the second rail member so that the third driving member drives the second driving head in one direction, thereby realizing bidirectional movement of the second rail member in the first direction, simplifying the driving operation of the third driving element, and improving production efficiency.

[0012] In some embodiments of the present application, the third driver can drive the second driver head to move along the third direction. The second driver head is provided with a guide slope. The guide slope gradually moves away from the first rail member along the third direction. The guide slope can abut against the second rail member.

[0013] In the above embodiment, the second driving head pushes and moves the second rail member via the guide slope. The second driving head moves in a direction perpendicular to the first direction X to realize a driving operation on the second rail member, and reduces the occupancy rate of the space where the second rail member moves away from the first rail member along the first direction X.

[0014] In some embodiments of the present application, the track assembly further includes a guide tube and a guide pin. The guide tube is disposed on the first fixed seat. The guide tube extends along a first direction. The guide pin is disposed on the second rail member. The guide pin is inserted into the guide tube. The guide pin is movable along the first direction relative to the guide tube.

[0015] In the above embodiment, the guide tube restricts the movement of the guide pin along the first direction X, thereby restricting the movement of the second rail member along the first direction X relative to the first rail member, thereby preventing the transport path from moving freely in directions other than the first direction X.

[0016] In some embodiments of the present application, the feed assembly further includes a guide seat. The guide seat is provided with a guide groove. The guide groove extends toward the transport path. The guide groove is used to pass the belt. The first driving head is a turntable. The first driving element drives and rotates the turntable. The rotation axis of the turntable is parallel to the first direction. The turntable and the guide groove are distributed along a third direction.

[0017] In the above embodiment, when the turntable rotates, the belt in the guide groove is moved and moved, and the belt is guided by the guide groove and accurately enters the transport path.

[0018] In some embodiments of the present application, the turntable has a number of teeth on its periphery.

[0019] In the above embodiment, as the turntable rotates, each tooth sequentially contacts the belt, increasing the pressure that the turntable exerts on the belt and preventing slippage between the turntable and the belt, thereby increasing stability when the feed assembly drives and moves the belt.

[0020] In some embodiments of the present application, the feed assembly further includes a second fixed seat and a fourth driver. The first driver and the guide seat are provided on the second fixed seat. The second fixed seat is provided on the fourth driver. The fourth driver can drive the second fixed seat to move along the first direction.

[0021] In the above embodiment, the second fixed seat moves the first driver, the turntable and the guide seat to move along the first direction, and when the transport path changes distance in the first direction, the guide groove automatically aligns with the center of the transport path in the first direction X, and the positions of the first driver and the turntable are adjusted to stably move the belt in the guide groove, thereby improving the accuracy with which the belt is transported between the feed assembly and the track assembly.

[0022] In some embodiments of the present application, the limit assembly further includes a connecting arm and a second elastic member. One end of the connecting arm is rotatably connected to the first rail member. The pressing member is provided at the other end of the connecting arm. The second driver is abutted against the connecting arm or the pressing member. One end of the second elastic member is connected to the first rail member. The other end of the second elastic member is connected to the connecting arm or the pressing member.

[0023] In the above embodiment, the second elastic member applies an elastic force to the connecting arm or the pressing member so that the second driver drives the connecting arm or the pressing member in one direction to reset the pressing member, thereby realizing bidirectional movement of the pressing member in the third direction, simplifying the driving operation of the second driver, and improving production efficiency.

[0026] Hereinafter, technical aspects of the embodiments of the present application will be described in conjunction with the drawings of the embodiments of the present application. However, it is apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to be limiting of the present application.

[0028] As used herein, the terms "first," "second," and "third," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0029] An embodiment of the present application provides a belt feeder. It is defined that the first direction, the second direction, and the third direction are perpendicular to each other. The belt feeder includes a track assembly, a feed assembly, and a limit assembly. The track assembly includes a first rail member and a second rail member. The first rail member is used to support the belt. The first rail member and the second rail member are arranged to face each other along the first direction and surround each other to form a transport path. The transport path extends along the second direction. The second rail member is movable along the first direction relative to the first rail member. The feed assembly includes a first driver and a first driver head. The first driver is fixedly arranged relative to the first rail member. The first driver head is provided on the first driver. The first driver can drive the movement of the first driver head. The first driver head is used to move and move the belt along the transport path. The limit assembly includes a second driver and a presser member. The second driver is fixedly arranged relative to the first rail member. The pressing member is provided on the first rail member. The second driver drives the pressing member to move it along the third direction. The pressing member and the first rail member are in contact with both sides of the belt along the third direction.

[0030] The first driver moves the belt by the first driver head to move it in the transport path. As a result, the transport belt moves along the second direction. By moving the second rail member, the belts of different lengths extend in the first direction, and the distance in the first direction of the transport path is changed so that the belts are restricted by the boundary of the transport path in the first direction and the belts are prevented from freely changing direction in the first direction while moving in the transport path. The second driver presses the belt against the first rail member along the third direction by driving the pressing member, thereby restricting the position of the belt in the third direction. Then, by changing the position of the pressing member in the third direction by the second driver, the belts of different lengths extend in the third direction, and the belts are restricted in position in the third direction by cooperation between the pressing member and the first rail member, and the belts are prevented from freely changing direction in the third direction while moving in the transport path. Therefore, in two directions perpendicular to the belt transport direction, the belt feed device can effectively match belts of different specifications and maintain stable transportation of belts of different specifications.

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, some embodiments of the present application will be described in detail with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other if there is no conflict.

[0032] 1 and 4, an embodiment of the present application provides a belt feeding device 100 for transporting a belt 200. In the present application, a first direction X, a second direction Y, and a third direction Z are defined as two-by-two perpendicular to each other.

[0033] The belt feeder 100 includes a track assembly 1, a feed assembly 2, and a limit assembly 3. The track assembly 1 includes a first rail member 11 and a second rail member 12. The first rail member 11 is used to place the belt 200. The first rail member 11 and the second rail member 12 are disposed opposite to each other along a first direction X, and surround each other to form a transport path 13. The transport path 13 is used to transport the belt 200. The transport path 13 extends along a second direction Y. The second rail member 12 is movable along the first direction X relative to the first rail member 11. The feed assembly 2 includes a first driver 21 and a first driver head 22 (see FIG. 3). The first driver 21 is fixedly provided to the first rail member 11. The first driver head 22 is provided to the first driver 21. The first driver 21 can drive the first driver head 22 to move. The first driving head 22 is used to move the belt 200 along the transport path 13. The limit assembly 3 includes a second driving element 31 and a pressing member 32. The second driving element 31 is fixedly provided with respect to the first rail member 11. The pressing member 32 is provided on the first rail member 11. The second driving element 31 can drive the pressing member 32 to move it along the third direction Z. The pressing member 32 and the first rail member 11 are abutted against opposing sides of the belt 200 along the third direction Z.

[0034] The first driver 21 moves the belt 200 via the first driver head 22 to move the belt 200 in the transport path 13, thereby moving the belt 200 in the second direction Y. By moving the second rail member 12 to change the distance in the first direction X of the transport path 13, the belt 200 extends with different lengths in the first direction X so that the belt 200 is prevented from freely changing direction in the first direction X while moving in the transport path 13, and the belt 200 is restricted in the first direction X by the boundary of the transport path 13. The second driver 31 drives the pressing member 32 to press the belt 200 against the first rail member 11 along the third direction Z, thereby restricting the position of the belt 200 in the third direction Z. Then, by changing the position of the presser member 32 in the third direction Z by the second driver 31, belts 200 of different lengths extend in the third direction Z, and the position of the belt 200 is restricted in the third direction Z by the cooperation of the presser member 32 and the first rail member 11, while preventing the belt 200 from freely changing direction in the third direction Z while moving within the transport path 13. Therefore, the belt feed device 100 can effectively match belts 200 of different specifications in two directions perpendicular to the transport direction of the belt 200, and can maintain stable transport of the belts 200 of different specifications.

[0035] 4, in some embodiments, when the first rail member 11 and the second rail member 12 are surrounded to form the transport path 13, the transport path 13 is not limited to being completely closed in a direction perpendicular to the second direction Y, and the existence of a partial gap is permitted. The transport path 13 is not limited to extending completely linearly along the second direction Y, and it is permitted that the transport path 13 bends as it extends and that there is a certain angle between the extension direction of the transport path 13 and the second direction Y, as long as it can transport the belt 200 in the second direction Y.

[0036] 1 and 2, in some embodiments, the transport path 13 has an entrance 131 and an exit 132. The feed assembly 2 and the limit assembly 3 are distributed on both sides of the transport path 13 along the first direction X. The feed assembly 2 is located on the side of the transport path 13 where the entrance 131 is located. The limit assembly 3 is located on the side of the transport path 13 where the exit 132 is located.

[0037] As shown in FIG. 4, in some embodiments, the first rail member 11 includes a first stopper surface 111 and a second stopper surface 112. The second rail member 12 includes a third stopper surface 121 and a fourth stopper surface 122. The first stopper surface 111 and / or the second stopper surface 112 are used to carry the belt 200. The first stopper surface 111 and the third stopper surface 121 are distributed along the third direction Z. The second stopper surface 112 and the fourth stopper surface 122 are distributed along the second direction Y. The first stopper surface 111, the second stopper surface 112, the third stopper surface 121 and the fourth stopper surface 122 are surrounded to form a transport path 13.

[0038] The first stopper surface 111 and the third stopper surface 121 restrict the movement range of the belt 200 in the third direction Z. The second stopper surface 112 and the fourth stopper surface 122 restrict the movement range of the belt 200 in the first direction X. This prevents the belt 200 from freely changing direction in a direction perpendicular to the transport direction while moving in the transport path 13. When the belt 200 is placed on the first stopper surface 111 and / or the second stopper surface 112, the movement of the belt 200 in the transport path 13 is not affected when the third stopper surface 121 and the fourth stopper surface 122 move in accordance with the movement of the second rail member 12. This allows the transport of the belt 200 in the transport path 13 and the adjustment of the transport path 13 in the first direction X to be performed simultaneously, thereby improving production efficiency.

[0039] 4, in some embodiments, the first stopper surface 111 is connected to the second stopper surface 112, and the third stopper surface 121 is connected to the fourth stopper surface 122. The third stopper surface 121 can be abutted against the side of the first stopper surface 111 facing away from the second stopper surface 112.

[0040] As shown in FIGS. 1 and 4, in some embodiments, in the belt feeding device 100, in a usage state, the third direction Z is parallel to the direction of gravity, and the first stopper surface 111 places the belt 200 thereon.

[0041] As shown in FIGS. 1 to 3, in some embodiments, the track assembly 1 further includes a first fixed seat 14, a third driver 15, and a second driver head 16. The first fixed seat 14 is plate-shaped. The first fixed seat 14 is fixedly provided with respect to the first rail member 11. The third driver 15 is provided on the first fixed seat 14. The second driver head 16 is provided on the third driver 15. The third driver 15 can drive and move the second driver head 16. The second driver head 16 can move the second rail member 12 along the first direction X. In the first direction X, the second rail member 12 is located between the first rail member 11 and the first fixed seat 14. The third driver 15 moves the second rail member 12 via the second driver head 16 based on the first fixed seat 14, thereby realizing automatic adjustment of the transportation path 13 in the first direction X. In some embodiments, the third actuator 15 includes, but is not limited to, a cylinder or a motor.

[0042] As shown in FIGS. 1 to 3, in some embodiments, the track assembly 1 further includes a first elastic member 17. The first elastic member 17 is coupled to the second rail member 12 and the first fixed seat 14, respectively. The second driving head 16 is abutted against the second rail member 12. The first elastic member 17 can apply an elastic force to the second rail member 12 to reset the second rail member 12 so that the third driving element 15 drives the second driving head 16 in one direction. In this way, bidirectional movement of the second rail member 12 in the first direction X can be realized, the driving operation of the third driving element 15 can be simplified, and productivity can be improved. The first elastic member 17 is disposed along the first direction X to supply an elastic force along the first direction X to the second rail member 12.

[0043] As shown in FIGS. 1 to 3, in some embodiments, the second driving head 16 pushes the second rail member 12 so that the second rail member 12 approaches the first rail member 11 along the first direction X. The first elastic member 17 pulls the second rail member 12 to move it away from the first rail member 11 along the first direction X. In other embodiments, the second driving head 16 pulls the second rail member 12 to move it away from the first rail member 11 along the first direction X, and the first elastic member 17 pushes the second rail member 12 to approach the first rail member 11 along the first direction X. In still other embodiments, the first elastic member 17 may be omitted, the second driving head 16 is fixedly connected to the second rail member 12, and the second driving head 16 moves the second rail member 12 to reciprocate along the first direction X.

[0044] As shown in FIGS. 1 to 3, in some embodiments, the third driver 15 can drive the second driver head 16 to move it along the third direction Z. The second driver head 16 is provided with a guide slope 161. The guide slope 161 gradually moves away from the first rail member 11 along the third direction Z. The guide slope 161 can come into contact with the second rail member 12. The second driver head 16 pushes and moves the second rail member 12 via the guide slope 161. The second driver head 16 moves in a direction perpendicular to the first direction X to realize a driving operation for the second rail member 12, thereby reducing the occupancy rate of the space in which the second rail member 12 moves away from the first rail member 11 side along the first direction X.

[0045] 3 and 4, in some embodiments, the second drive head 16 further includes a first positioning surface 162 and a second positioning surface 163. The first positioning surface 162 and the second positioning surface 163 are both perpendicular to the first direction X and are located on both sides of the guide slope 161 along the third direction Z. When the first positioning surface 162 abuts against the second rail member 12, the distance of the transportation path 13 in the first direction X becomes the maximum value within the adjustable range. When the second positioning surface 163 abuts against the second rail member 12, the distance of the transportation path 13 in the first direction X becomes the minimum value within the adjustable range.

[0046] As shown in Figures 3 and 4, in some embodiments, the second drive head 16 is block-shaped, and has a communicating cavity 164 extending along the first direction X, so that the second drive head 16 forms a frame-type structure, and the second drive head 16 itself provides sufficient support for the guide slope 161, the first positioning surface 162 and the second positioning surface 163, thereby avoiding deformation, reducing the weight of the second drive head 16, and reducing the driving force required by the third drive element 15 to operate the second drive head 16.

[0047] 1, 3 and 4, in some embodiments, the track assembly 1 further includes a guide tube 18 and a guide pin 19. The guide tube 18 is provided on the first fixed seat 14 and extends along a first direction X. The guide pin 19 is provided on the second rail member 12. The guide pin 19 is inserted into the guide tube 18. The guide pin 19 is movable relative to the guide tube 18 along the first direction X.

[0048] The guide tube 18 restricts the movement of the guide pin 19 along the first direction X, thereby restricting the movement of the second rail member 12 along the first direction X relative to the first rail member 11, and prevents the transport path 13 from moving freely in directions other than the first direction X.

[0049] As shown in FIG. 2, in some embodiments, the first elastic member 17 is provided within the guide tube 18, one end of the first elastic member 17 is connected to the guide pin 19, and the other end of the first elastic member 17 is connected to the first fixed seat 14.

[0050] As shown in FIG. 2 and FIG. 3, in some embodiments, the feed assembly 2 further includes a guide seat 23. The guide seat 23 is provided with a guide groove 231. The guide groove 231 extends toward the transport path 13. The guide groove 231 is used to pass the belt 200. The first driving head 22 is a turntable 221. The first driver 21 drives the turntable 221 to rotate. The rotation axis of the turntable 221 is parallel to the first direction X. The turntable 221 and the guide groove 231 are distributed along the third direction Z. The turntable 221 rotates to move the belt 200 in the guide groove 231. The belt 200 is guided by the guide groove 231 to accurately enter the transport path 13. The first driver 21 includes, but is not limited to, a motor.

[0051] In another embodiment, the first driving head 22 may be a conveyor belt. The first driving element 21 and the first driving head 22 drive and move the belt 200 in the form of a belt transmission.

[0052] 3, in some embodiments, the guide seat 23 is further provided with two guide openings 232 distributed on both sides of the guide groove 231 along the second direction Y. The belt 200 enters the guide groove 231 through the guide opening 232 on the side away from the transport path 13, and leaves the guide groove 231 via the guide opening 232 on the side toward the transport path 13. The guide opening 232 has a completely closed boundary perpendicular to the second direction Y, which prevents the belt 200 from leaving and improves the accuracy of the guide seat 23 in guiding the moving direction of the belt 200.

[0053] 3, in some embodiments, the outer periphery of the turntable 221 is provided with a number of teeth 222. As the turntable 221 rotates, each tooth 222 contacts the belt 200 in turn, increasing the pressure that the turntable 221 applies to the belt 200, preventing slippage between the turntable 221 and the belt 200, and improving stability when the feed assembly 2 drives and moves the belt 200. In other embodiments, the teeth 222 may be omitted, and the outer periphery of the turntable 221 may directly contact the belt 200.

[0054] As shown in FIGS. 1 to 3, in some embodiments, the feed assembly 2 further includes a second fixed base 24 and a fourth driver 25. The first driver 21 and the guide base 23 are provided on the second fixed base 24. The second fixed base 24 is provided on the fourth driver 25. The fourth driver 25 can drive the second fixed base 24 to move along the first direction X.

[0055] The second fixed seat 24 moves the first driver 21, the turntable 221 and the guide seat 23 in the first direction X. When the transport path 13 changes its distance in the first direction X, the guide groove 231 automatically aligns with the center of the transport path 13 in the first direction X, and the positions of the first driver 21 and the turntable 221 are adjusted to stably move the belt 200 in the guide groove 231, thereby improving the accuracy with which the belt 200 is transported between the feed assembly 2 and the track assembly 1.

[0056] 1 to 3, in some embodiments, the feed assembly 2 further includes a third fixed seat 26. The third fixed seat 26 is provided on the first fixed seat 14, and the fourth driver 25 is provided on the third fixed seat 26. The first driver 21 and the second rail member 12 are located on the same side of the belt 200 in the first direction X, making it convenient for the fourth driver 25 to adjust the position of the first driver 21 with reference to the position of the second rail member 12.

[0057] As shown in FIGS. 1 to 3, in some embodiments, the limit assembly 3 further includes a connecting arm 33 and a second elastic member (not shown). One end of the connecting arm 33 is rotatably connected to the first rail member 11. The pressing member 32 is provided at the other end of the connecting arm 33. The second driver 31 abuts against the connecting arm 33 or the pressing member 32. One end of the second elastic member is connected to the first rail member 11. The other end of the second elastic member is connected to the connecting arm 33 or the pressing member 32. In some embodiments, the pressing member 32 is provided integrally with the connecting arm 33.

[0058] The second elastic member can apply an elastic force to the connecting arm 33 or the pressing member 32 to reset the pressing member 32 so that the second driver 31 drives the connecting arm 33 or the pressing member 32 in one direction. This allows the pressing member 32 to move in both directions in the third direction Z, simplifies the driving operation of the second driver 31, and improves production efficiency.

[0059] As shown in FIGS. 1 to 3, in some embodiments, the second driver 31 pushes and moves the pressing member 32 away from the first rail member 11 along the third direction Z, and the second elastic member pulls and moves the pressing member 32 toward the first rail member 11 along the third direction Z. The elastic force applied to the pressing member 32 by the second elastic member keeps the pressing member 32 in contact with the belt 200. In other embodiments, the second driver 31 pushes and moves the pressing member 32 toward the first rail member 11 along the third direction Z, and the second elastic member pulls the pressing member 32 away from the first rail member 11 along the third direction Z. In other embodiments, the second elastic member may be omitted, the second driver 31 is fixedly connected to the pressing member 32, and the second driving head 16 moves the pressing member 32 to reciprocate along the third direction Z.

[0060] As shown in FIGS. 1 to 3, in some embodiments, the second driver 31 includes a first driver 311, a second driver 312, and a third driver head 313. The first driver 311 is fixedly provided with respect to the first rail member 11. The second driver 312 is provided in the first driver 311. The first driver 311 can drive the second driver 312 to move along the third direction Z. The third driver head 313 is provided in the second driver 312. The second driver 312 can drive the third driver head 313 to move along the first direction X. A sharp portion 3131 is provided on the third driver head 313 on the side facing the first rail member 11 and the pressing member 32. The cross section of the sharp portion 3131 has a tapered shape.

[0061] When the third driving head 313 moves close to the first rail member 11 and the pressing member 32 along the first direction X, the sharp portion 3131 is inserted between the first rail member 11 and the pressing member 32, and further pushes the pressing member 32 away from the first rail member 11 along the third direction Z. When the sharp portion 3131 is inserted between the first rail member 11 and the pressing member 32, the distance between the pressing member 32 and the first rail member 11 is not sufficient to allow the belt 200 to pass. Then, the first driving unit 311 drives the second driving unit 312 to move along the third direction Z. As a result, the sharp portion 3131 moves away from the first rail member 11 along the third direction Z in conjunction with the first rail member 11, and the distance between the pressing member 32 and the first rail member 11 is further increased in the third direction Z. The first driving unit 311 and the second driving unit 312 include, but are not limited to, a cylinder or a motor.

[0062] As shown in FIG. 1, in some embodiments, the belt 200 is an elongated belt structure.

[0063] 1, 3 and 4, in some embodiments, the operation principle of the belt feeding device 100 is as follows. The third driver 15 drives and moves the second driver head 16, so that the second driver head 16 pushes the second rail member 12 through the guide inclined surface 161 until a distance in the first direction X of the transport path 13 becomes equal to the width of the current belt 200. The fourth driver 25 drives and moves the third fixed seat 26 in the first direction X so that the guide groove 231 faces the middle position of the transport path 13 in the first direction X. The second driver 312 drives the third driver head 313 to move in the first direction X. The sharp portion 3131 is inserted between the first rail member 11 and the pressing member 32. The first driver 21 drives and rotates the turntable 221. The turntable 221 moves the belt 200 from the guide groove 231 to the transport path 13, and continuously moves the belt 200 within the transport path 13. After the belt 200 passes between the first rail member 11 and the press member 32, the second driving unit 312 drives the third driving head 313 to move in the opposite direction, so that the pointed portion 3131 is released from between the first rail member 11 and the press member 32, the press member 32 is pressed against the belt 200, and the turntable 221 continues to move the belt 200.

[0064] In the present application, the fact that the two are fixed relative to each other does not mean that they cannot be removed, but means that when the belt feeding device 100 is in use, the two fixed relative to each other can move together.

[0065] The above embodiments are only used to describe the technical aspects of the present application, not to limit it, and the present application has been described in detail with reference to the above preferred embodiments, but those skilled in the art should understand that even if the technical aspects of the present application are modified or replaced with equivalents, they should not deviate from the spirit and scope of the technical aspects of the present application.
