Description

Technical Field

[0001] The utility model relates to a mechanical transmission device, in particular to a deviation-correcting device for a transmission mechanism and a transmission machine. Background Art

[0002] During the transmission process of the conveyor, axial deviation of the conveyor belt is a common problem. The main reasons can be attributed to the following aspects: First, the conveyor belt may deviate due to uneven tension during installation or long-term use; second, uneven wear of the pulleys or deviation in the installation position may also cause the conveyor belt to deviate; finally, environmental factors such as temperature, humidity changes or external vibrations may also affect the stability of the conveyor belt.

[0003] When the conveyor belt deflects axially, its relative position to the pulley changes, causing friction between the belt and the non-working surface of the pulley. This abnormal friction not only causes increased wear on the conveyor belt and pulley, increasing equipment maintenance costs and downtime, but more importantly, the dust generated during this friction can enter the equipment, causing further damage. This dust is particularly harmful during the transportation of TopCon solar cells, as it can damage the cell's passivation layer, reducing its effectiveness and, in turn, affecting the cell's performance and lifespan. Furthermore, dust adhering to the cell surface reduces its light absorption efficiency, directly affecting photovoltaic conversion efficiency and output power.

[0004] In order to solve the problem of axial deviation of the conveyor belt, there are two main types of correcting devices on the market: active correcting devices and passive correcting devices. The active correcting device monitors the status of the conveyor belt in real time through sensors and transmits the signal to the main controller. The main controller controls the servo motor or hydraulic cylinder and other equipment to adjust the pulley or auxiliary wheel to achieve automatic correction of the conveyor belt. However, this type of device is expensive and large in size, and is not suitable for the transmission of small devices such as TopCon batteries. Passive correcting devices mainly prevent deviation by changing the shape of the working surface of the conveyor belt or pulley (for example, relying on the groove between the conveyor belt and the pulley to prevent deviation). However, since the pulley is fixed in the axial position, when the conveyor belt is axially offset, it is still impossible to effectively avoid friction and dust generation. Utility Model Content

[0005] One of the purposes of the utility model is to provide a deviation-correcting device for a transmission mechanism, which has a simple structure, low cost, and can effectively avoid friction between a transmission belt and a pulley.

[0006] In order to achieve the above-mentioned object, the utility model provides a deviation-correcting device for a transmission mechanism, which is used to be connected to a transmission belt assembly, wherein the transmission belt assembly includes a pulley capable of rotating around its own axis and moving along its axial direction, and a transmission belt wrapped around the pulley, and the deviation-correcting device includes:

[0007] a deflection correction assembly comprising a first deflection correction unit provided at one axial end of the pulley and a second deflection correction unit provided at the other axial end of the pulley, wherein the first deflection correction unit and the second deflection correction unit are both configured to convert an extrusion force generated by the axial deviation of the transmission belt into a force controlling the pulley to move in a corresponding deflection direction, so that the pulley moves adaptively along the deflection direction of the transmission belt; and

[0008] The elastic floating assembly comprises a first elastic member arranged at one axial end of the pulley and a second elastic member arranged at the other axial end of the pulley, wherein the first elastic member and the second elastic member respectively apply elastic forces to the two axial ends of the pulley.

[0009] Furthermore, the first correcting unit and the second correcting unit each include a transition part, a force-bearing part and a same-direction force-applying part connected into one body, and the transition part rotates around the first rotating shaft; when the force-bearing part is subjected to an axial outward extrusion force generated by the axial offset of the transmission belt, the extrusion force is transmitted to the transition part and the same-direction force-applying part, so that the extrusion force is amplified by the transition part and then transmitted to the same-direction force-applying part, so that the same-direction force-applying part moves outward in the same direction and compresses the elastic member on the same side; the first elastic member and / or the second elastic member pushes the pulley to move in the offset direction of the transmission belt based on its own elastic force, so that the pulley moves adaptively along the offset direction of the transmission belt.

[0010] Furthermore, the adapter portion is located outside the side of the force-bearing portion away from the transmission belt along the axial direction of the pulley, and the vertical distance between the adapter portion and the pulley is greater than the vertical distance between the force-bearing portion and the pulley.

[0011] Furthermore, the first correction unit and the second correction unit are both configured as a fork structure, and the fork structure includes a main body block; the adapter is configured as a rotating drum arranged at one end of the main body block, and the rotating drum is rotatably connected to the first rotating shaft; the force-bearing part is configured as a roller arranged on the side of the main body block facing the transmission belt, and the rolling surface of the roller faces the transmission belt; the same-direction force-applying part is configured as a fork arranged on the end of the main body block away from the rotating drum, and the fork is inserted between the corresponding end face of the pulley and the corresponding elastic member along a direction perpendicular to the axial direction.

[0012] Furthermore, the rollers are configured in number, and the two rollers are respectively adapted to the heights of the upper conveyor belt and the lower conveyor belt of the conveyor belt.

[0013] Furthermore, a transfer seat is provided on a side of the main body block facing the conveyor belt, a second rotating shaft distributed in a vertical direction is provided on the transfer seat, and the roller is configured to be rotatably sleeved on the outer periphery of the second rotating shaft.

[0014] Furthermore, the first correcting unit and the second correcting unit each include a shift block disposed between the corresponding end surface of the pulley and the corresponding elastic member, and the shift block is provided with a slot for the shift fork to be inserted into along a direction perpendicular to the axial direction.

[0015] Another object of the present invention is to provide a conveyor that can effectively avoid friction between the conveyor belt pulleys, thereby significantly reducing the generation of dust during the transmission process.

[0016] In order to achieve the above-mentioned purpose, the utility model also provides a conveyor, including a transmission belt assembly, wherein the transmission belt assembly includes a pulley capable of rotating around its own axis and moving along its axial direction and a transmission belt wrapped around the pulley. In addition, it also includes a correction device for the transmission mechanism as described above.

[0017] Furthermore, the pulley is mounted on a pulley seat, and the pulley seat includes a first side seat and a second side seat respectively arranged at both axial ends of the pulley, and a first rotating shaft is provided on the first side seat and the second side seat on one side facing the transmission direction; the connecting parts of the first correcting unit and the second correcting unit are respectively connected to the outer periphery of the two first rotating shafts;

[0018] The pulley seat also includes a support shaft connected to the first side seat and the second side seat at both ends respectively; the pulley is sleeved on the outer circumference of the support shaft through a linear bearing so that it can rotate around its axis and move along its axial direction; the first elastic member is wrapped around the outer circumference of the support shaft and elastically abuts between the first side seat and the first end face of the pulley, and the second elastic member is wrapped around the outer circumference of the support shaft and elastically abuts between the second side seat and the second end face of the pulley.

[0019] Furthermore, a shift block is movably connected at a position between the pulley and the first elastic member and at a position between the pulley and the second elastic member on the support shaft. The shift block includes a ring body movably connected to the outer periphery of the support shaft in the axial direction, a first retaining ring formed at one axial end of the ring body, and a second retaining ring formed at the other axial end of the ring body. The radial dimensions of the first retaining ring and the second retaining ring are both larger than the radial dimensions of the ring body so as to form an annular slot together with the ring body; the shift forks of the first correcting unit and the second correcting unit are inserted into the annular slot along the transmission direction of the transmission belt.

[0020] The deviation-correcting device for a transmission mechanism and the conveyor of the present invention have the following beneficial effects:

[0021] The structures of the first correcting unit and the second correcting unit are designed based on the principle of lever. The force-bearing part is used as the lever power arm, which is used to receive the extrusion force generated by the axial deviation of the transmission belt and use it as power; the transition point is used as a rotation fulcrum, which receives and amplifies the force from the force-bearing part and transmits it to the fork, and the force-applying part in the same direction is used as the resistance arm, which is used to transmit the amplified force in the same direction to the corresponding elastic part, thereby making the pulley move adaptively along the deviation direction of the transmission belt.

[0022] The utility model does not require expensive components such as sensors, main controllers, and pulley adjustment mechanisms. It can effectively prevent the deviation of the transmission belt and pulley only through the mechanical structure, eliminate the friction caused by their deviation, avoid dust generation, and increase the service life of the conveyor. It is suitable for the transmission of dust-sensitive products such as TopCon batteries. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will further explain the correction device for the transmission mechanism and the conveyor described in the present invention in combination with the drawings and specific implementation methods of the specification, but this explanation does not constitute an improper limitation on the technical solution of the present invention.

[0031] See Figure 1 and Figure 2 , Figure 1This is a schematic diagram of the assembly of the utility model's deviation correction device on the conveyor belt assembly of the conveyor. Figure 2 yes Figure 1 Cross-sectional view of AA in the figure.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the conveyor may include a pulley seat 100, a pulley 210 mounted on the pulley seat 100, and a conveyor belt 220 wrapped around the pulley 210, and the conveyor belt 220 and the pulley 210 constitute a conveyor belt assembly 200 of the conveyor.

[0033] The conveyor can be any known conveyor, as long as the pulley 210 can rotate around its axis and move along its axial direction. Figure 1 The correcting device for the transmission mechanism and the conveyor belt assembly 200 of the conveyor are exemplarily described to more clearly illustrate the cooperation relationship between the correcting device and the conveyor belt assembly 200. It should be understood that although the following Figure 1 The specific embodiment shown is described in detail as an example, but this specific embodiment is not used to limit the scope of the present invention's correction device for a transmission mechanism and a conveyor structure. Except for the components that solve the necessary technical problems of the present invention, the remaining components can be regarded as non-essential technical elements. These non-essential technical elements can be replaced by other technical elements with the same or similar functions or structures in other embodiments, or these non-essential technical elements may not be needed in other embodiments.

[0034] To more clearly illustrate the placement and orientation of each component, the axial direction referred to below is represented by the X-axis in the coordinate system, and the transport direction of the transport belt 220 is represented by the Y-axis in the coordinate system. The Y-axis is perpendicular to the X-axis, and the Y-axis and the X-axis form a horizontal plane. The vertical direction perpendicular to the horizontal plane is represented by the Z-axis in the coordinate system. Thus, there is an axial direction X, a transport direction Y, and a vertical direction Z.

[0035] The pulley seat 100 includes a first side seat 10a and a second side seat 10b, which are arranged at the axial ends of the pulley 210 along the axial direction X, and a support shaft 10c connected to the first side seat 10a and the second side seat 10b at both ends. A linear bearing 10d is sleeved on the outer periphery of the support shaft 10c, and the pulley 210 is sleeved on the outer periphery of the support shaft 10c via the linear bearing 10d so that it can rotate around its axis and move along its axial direction. When the pulley 210 is assembled on the outer periphery of the support shaft 10c via the linear bearing 10d, sufficient space is reserved between the axial ends of the pulley 210 and the first side seat 10a and the second side seat 10b to install components such as the elastic floating assembly 400 described below.

[0036] See Figure 3 The first side seat 10a and the second side seat 10b can be fixed on a plane or platform by any fixing method. The plane or platform can be but not limited to Figure 1 The base 10e shown in FIG. 1 may be fixed in a manner which is not limited to Figure 1 The first side seat 10a and the second side seat 10b are both vertically arranged on the base 10e, and each of them has a support portion 110 and a fixing portion 120 formed on both sides of the support portion 110 along the transmission direction Y.

[0037] The support portion 110 is configured as a block-shaped structure. Each support portion 110 has a support hole 111 extending through the support portion 110 in the axial direction X for supporting the support shaft 10c. Each support hole 111 extends upward through the support portion 110 in the vertical direction Z to form a slit 112. This slit 112 divides the portion of the support portion 110 above the support hole 111 into two, forming a first support block 113 and a second support block 114 spaced apart along the transmission direction Y. The first support block 113 and the second support block 114 can move toward each other or away from each other under the action of an external force. The first support block 113 and the second support block 114 are both provided with a first screw hole 115 along the transmission direction Y. The two first screw holes 115 are connected by a first bolt (not shown). After the first bolt is screwed into the two first screw holes 115, the first support block 113 and the second support block 114 can be pulled together to reduce the gap between the slits 112, thereby reducing the size of the support hole 111. When assembling the support shaft 10c, the two ends of the support shaft 10c are first inserted into the support holes 111 at the two support portions 110. Then, the first bolts are screwed into the first screw holes 115 of the first support block 113 and the second support block 114 in sequence to pull the first support block 113 and the second support block 114 together, thereby gradually reducing the size of the support hole 111 to fit tightly with the support shaft 10c.

[0038] See Figure 4 and Figure 5 Each of the fixing portions 120 is configured as a table-like structure, which is much lower than the height of the support portion 110. Each of the fixing portions 120 has a fixing hole 121 arranged in a vertical direction, which is used to cooperate with a fixing bolt to fix the fixing portion 120 to the base 10e. Preferably, the fixing bolt is configured as a second bolt 122, which is much higher than the fixing portion 120. The second bolt 122 has a first outer thread arranged on a lower section of the second bolt 122 to form a first outer thread section 122a, which is screwed into a second screw hole 101 of the base 10e. The second bolt 122 has a second outer thread arranged on an upper section of the second bolt 122 to form a second outer thread section 122b, which has an upper end surface higher than the top end surface of the support portion 110, and a sleeve 123 is screwed onto the outer periphery of the second outer thread section 122b. Herein, the two sleeves 123 on the side of the other end pulley base (not shown) along the transmission direction Y are referred to as first rotation shafts 124 in the following, which are used to provide a rotation fulcrum for the first and second deviation correcting units 30a and 30b in the following. The second bolt 122 has a smooth surface arranged on a middle section 122c of the second bolt 122, which is used to pass through the fixing hole 121 and screw the first outer thread section 122a into the base 10e. In this way, the fixing bolt is used as a fixing member to fix the first side base 10a to the base 10e, and also as a mounting shaft of the sleeve 123, which provides the first rotation shaft 124 as a rotation fulcrum for the middle fork structure in the following. In this way, the one thing is used for multiple purposes, which can save the assembly space, reduce the structural complexity, reduce the manufacturing cost, and also improve the assembly speed. It should be understood that, in different embodiments, the structure of the fixing portion 120 and the fixing bolt can also be changed in other suitable manners. For example, the fixing bolt can be configured as a common bolt structure, which is only used to fix the fixing portion 120 to the base 10e. For another example, only the fixing bolts on the left side in Figure 4 the transmission direction Y are configured as the second bolt 122, and the fixing bolts away from the side of the other end pulley base (the right side in Figure 4 ) are configured as common bolts. For another example, the fixing portion 120 is fixed to the base 10e in any detachable manner.

[0039] Please continue to see Figure 2, the deviation correcting device adaptively corrects the position of the belt pulley 210 based on the deviation direction of the transmission belt 220, and includes a deviation correcting assembly 300 and an elastic floating assembly 400. The deviation correcting assembly 300 includes a first deviation correcting unit 30a arranged at one axial end of the belt pulley 210 along the axial direction X and a second deviation correcting unit 30b arranged at the other axial end of the belt pulley 210. The first deviation correcting unit 30a is arranged on the same side as the first side seat 10a, and the second deviation correcting unit 30b is arranged on the same side as the second side seat 10b. The first deviation correcting unit 30a and the second deviation correcting unit 30b are both used to convert the extrusion force of the transmission belt 220 due to axial deviation into a force for controlling the belt pulley 210 to move in the same deviation direction, so that the belt pulley 210 adaptively moves with the deviation direction of the transmission belt 220. The elastic floating assembly 400 includes a first elastic member 40a arranged at one axial end of the belt pulley 210 along the axial direction X and a second elastic member 40b arranged at the other axial end of the belt pulley 210. In the shown embodiment, the first elastic member 40a can be configured to be arranged around the outer periphery of the support shaft 10c and elastically abut between the corresponding end surface (first end surface) of the first side seat 10a and the belt pulley 210, and the second elastic member 40b can be configured to be arranged around the outer periphery of the support shaft 10c and elastically abut between the corresponding end surface (second end surface) of the second side seat 10b and the belt pulley 210. The first elastic member 40a and the second elastic member 40b respectively apply elastic force to the two axial ends of the belt pulley 210.

[0040] It should be noted that the first deviation correcting unit 30a and the second deviation correcting unit 30b here are not necessarily arranged directly opposite the two ends of the belt pulley 210 along the axial direction X. The arrangement position can be determined according to the size and space size of other components in different embodiments. For example, in the present embodiment, the first deviation correcting unit 30a and the second deviation correcting unit 30b are arranged to be offset from the belt pulley 210 along the transmission direction Y, i.e., the first deviation correcting unit 30a and the second deviation correcting unit 30b are arranged to be closer to the other end of the belt pulley seat along the transmission direction Y, and only need to be inserted between the corresponding end surface of the belt pulley 210 and the corresponding elastic member along the transmission direction Y.

[0041] The term "corresponding" as used herein refers to a component located on the same side as the first correcting unit 30a or the second correcting unit 30b. For example, the end face of the pulley 210 corresponding to the first correcting unit 30a refers to the end face located on the same side as the first correcting unit 30a, and the end face of the pulley 210 corresponding to the second correcting unit 30b refers to the end face located on the same side as the second correcting unit 30b. For example, the elastic member corresponding to the first correcting unit 30a refers to the elastic member located on the same side as the first correcting unit 30a, and the elastic member corresponding to the second correcting unit 30b refers to the elastic member located on the same side as the second correcting unit 30b. If the end face of the pulley 210 and the first correcting unit 30a located on the same side is defined as the first end face, and the elastic member on the same side is defined as the first elastic member 40a, then the unidirectional force-applying portion of the first correcting unit 30a is inserted into the first end face of the pulley 210 and the first elastic member 40a along the transmission direction Y. If the end surface of the pulley 210 and the second correcting unit 30b on the same side is defined as the second end surface, and the elastic member on the same side is defined as the second elastic member 40b, then the same-direction force-applying portion of the second correcting unit 30b is inserted into the second end surface of the pulley 210 and the second elastic member 40b along the transmission direction Y.

[0042] The first and second correcting units 30a, 30b each include an integrally connected adapter, a force-bearing portion, and a same-direction force-applying portion. The adapters of the first and second correcting units 30a, 30b rotate around the two first rotating shafts 124, respectively. The distance between the force-bearing portion and the corresponding side edge of the transmission belt 220 is smaller than the distance between the corresponding side edge of the transmission belt 220 and the corresponding edge of the pulley 210, so that when the transmission belt deviates, the side edge of the transmission belt can first contact and be squeezed by the force-bearing portion. The same-direction force-applying portion extends between the corresponding end face of the pulley 210 and the corresponding elastic member. When the force-bearing portion is subjected to an axial outward extrusion force generated by the axial deviation of the transmission belt 220, the extrusion force is transmitted to the adapter and the same-direction force-applying portion. The extrusion force is amplified by the adapter and then transmitted to the same-direction force-applying portion, causing the same-direction force-applying portion to move outward in the same direction and compress the elastic member on the same side. The elastic member at the other axial end of the pulley 210 pushes the pulley 210 to move in the offset direction of the transmission belt 220 based on its own elastic force, so that the pulley 210 can adaptively move along the offset direction of the transmission belt 220. The two first rotating shafts 124 can be configured on the first side seat 10a and the second side seat 10b according to the above configuration. The two first rotating shafts 124 can also be set independently of the pulley seat 100, for example, the two rotating shafts are respectively set outside the two sides of the transmission belt 220 along the axial direction X. Each first rotating shaft 124 is not limited to the sleeve 123 structure mentioned above, and any existing vertically arranged structure that can serve as a rotation fulcrum can be used.

[0043] The first and second deviation rectifying units 30a and 30b are configured as fork structures in the embodiment. The first and second deviation rectifying units 30a and 30b can also selectively include a block configured between a corresponding end surface of the pulley 210 and a corresponding elastic member for cooperating with the fork structure. The first deviation rectifying unit 30a includes a first adapter 310, a first force receiving portion 320, and a first co-directional force applying portion 330. The first adapter 310 is located on a side of the first force receiving portion 320 away from the transmission belt 220 in the axial direction X, and a vertical distance D1 between the first adapter 310 and the pulley 210 is greater than a vertical distance D2 between the first force receiving portion 320 and the pulley 210 (see Figure 2 ). Thus, a co-directional amplification force is generated, and the first co-directional force applying portion 330 can apply the co-directional amplification force to the first elastic member 40a. A distance between the first force receiving portion 320 and the first side edge of the transmission belt 220 is less than a distance between the first side edge of the transmission belt 220 and the first edge of the pulley 210, and the first co-directional force applying portion 330 extends between the first end surface of the pulley 210 and the first elastic member 40a.

[0044] Referring to Figure 6 , the first deviation rectifying unit 30a is configured as a first fork structure 300a including a first main block 340 that connects the first adapter 310, the first force receiving portion 320, and the first co-directional force applying portion 330. The first adapter 310 is configured as a first rotary cylinder 311 provided at one end of the first main block 340 and rotatably connected to the first rotary shaft 124. The first rotary cylinder 311 is screwed to the second external thread segment 122b of the second bolt 122, and a first gasket is provided between the first rotary cylinder 311 and the fixed portion 120. An upper end of the first rotary cylinder 311 is provided with a pressing block 312, and a second gasket is provided between the pressing block 312 and an upper end of the sleeve 123. The first force receiving portion 320 is configured as a first roller 321 provided on a side of the first main block 340 facing the transmission belt 220, and a rolling surface of the first roller 321 faces the transmission belt 220. The first co-directional force applying portion 330 is configured as a first fork 331 provided at one end of the first main block 340 away from the first rotary cylinder 311, and the first fork 331 is inserted between the first end surface of the pulley 210 and the first elastic member 40a in the transmission direction Y.

[0045] The first rollers 321 are configured in pairs, and the two first rollers 321 are respectively adapted to the height of the upper conveyor belt 221 and the lower conveyor belt 222 of the conveyor belt 220, so as to receive the axial extrusion force from the upper conveyor belt 221 and the lower conveyor belt 222, respectively. Each first roller 321 is mounted on a side of the first main body block 340 facing the conveyor belt 220 via a first adapter 350. Specifically, each first adapter 350 includes a first support 351 and a second support 352 spaced apart along the vertical direction Z. A shaft hole (not shown) is formed through each of the first support 351 and the second support 352 along the vertical direction Z. A second rotating shaft 353 is mounted in the shaft hole, and the first roller 321 is rotatably mounted on the outer periphery of the second rotating shaft 353. Preferably, the two first adapter seats 350 share a second rotating shaft 353, that is, the second rotating shaft 353 is provided on the first support 351 and the second support 352 of the two first adapter seats 350. In the illustrated embodiment, the first support 351 and the second support 352 are both extended obliquely from the first main body block 340 along the axial direction X and along the transmission direction Y toward the conveyor belt 220. That is, the ends of the first support 351 and the second support 352 connected to the first main body block 340 are closer to the pulley 210 along the transmission direction Y and closer to the first side seat 10a along the axial direction X, and the ends (extended ends) of the first support 351 and the second support 352 for assembling the first roller 321 are further away from the pulley 210 along the transmission direction Y and closer to the conveyor belt 220 along the axial direction X.

[0046] See Figure 2 and Figure 7 In the illustrated embodiment, the first deflection-correcting unit 30a further includes a first shift block 360 disposed between the first end surface of the pulley 210 and the first elastic member 40a. The first shift block 360 is provided with a first slot into which the first shift fork 331 is inserted along the transmission direction Y. The first shift block 360 is movably coupled to the support shaft 10c and located between the first end surface of the pulley 210 and the first elastic member 40a. The first shift block 360 includes a ring body 361 movably coupled to the outer circumference of the support shaft 10c in the axial direction, a first retaining ring 362 formed at one axial end of the ring body 361, and a second retaining ring 363 formed at the other axial end of the ring body 361. The radial dimensions of the first retaining ring 362 and the second retaining ring 363 are both larger than the radial dimensions of the ring body 361. The first slot is configured as a first annular slot 364 formed by the first retaining ring 362, the second retaining ring 363, and the outer circumferential surface of the ring body 361. The first fork 331 of the first correcting unit 30 a is inserted into the first annular slot 364 along the transmission direction of the transmission belt 220 .

[0047] The second correcting unit 30b has the same or similar structure or function as the first correcting unit 30a and is disposed at the second end of the pulley 210 along the axial direction X. The second correcting unit 30b includes a second adapter, a second force-bearing portion, a second force-applying portion, a second fork structure, a second rotating drum, a second main block, a second roller, a second adapter, a second block, and a second annular slot, which have the same or similar structure or function as the first correcting unit 310, the first force-bearing portion 320, the first unidirectional force-applying portion 330, the first fork 331 structure 300a, the first rotating drum 311, the first main block 340, the first roller 321, the first adapter seat 350, the first shift block 360, and the first annular slot 364. The structure of the second correcting unit 30b can be found in the description of the structure of the first correcting unit 30a and will not be further elaborated here.

[0048] Based on the above embodiments, the correction process of the correction device for the transmission mechanism and the conveyor described in the present invention is as follows:

[0049] (1) Correction of deviation of the transmission belt 220 on the first side: When the transmission belt 220 deviates toward the first side (the left side in the figure), since the distance between the first roller 321 and the first side edge of the transmission belt 220 is smaller than the distance between the first side edge of the transmission belt 220 and the first edge of the pulley 210, the transmission belt 220 preferentially squeezes the first roller 321; and since the force point of the first roller 321 is closer to the pulley 210 along the transmission direction Y and the rotation fulcrum is farther away from the pulley 210 along the transmission direction Y, the first roller 321 is squeezed toward the first side, thereby driving the shift fork structure The structure rotates clockwise, thereby causing the shift fork to squeeze the first elastic member 40a toward the first side direction. After being squeezed and contracted, the first elastic member 40a releases at least part of the elastic force applied to the first end face of the pulley 210, that is, the elastic force of the first elastic member 40a is less than the elastic force of the second elastic member 40b at the second end of the pulley 210 in this state. Therefore, at this time, the second elastic member 40b relies on its own elastic force to push the pulley 210 toward the first side direction, thereby causing the pulley 210 to move in the same direction and adaptively with the transmission belt 220, ensuring that the first side edge of the transmission belt 220 maintains a certain distance from the first edge of the pulley 210 to avoid friction between them. When the pulley 210 adaptively moves along with the conveyor belt 220 toward the first side, the first roller 321 is no longer squeezed by the conveyor belt 220, and the first shift fork 331 no longer pushes the first elastic member 40a toward the first side. Therefore, the first elastic member 40a pushes the pulley 210 toward the second side due to its own elastic force and returns to its original position (central position).

[0050] (2) Correction of the second side direction of the conveyor belt 220: Correction of the second side direction of the conveyor belt 220 is performed in a direction opposite to the direction of the first side direction of the conveyor belt 220.

[0051] In summary, the deviation correction device for the transmission mechanism and the conveyor of the present invention have the following beneficial effects: the structure of the first deviation correction unit and the second deviation correction unit is designed based on the lever principle, and the force-bearing part is used as a lever power arm, which is used to receive the extrusion force generated by the axial deviation of the transmission belt and use it as power; the adapter is used as a rotation fulcrum to receive and amplify the force from the force-bearing part and transmit it to the shift fork, and the same-direction force-applying part is used as a resistance arm, which is used to transmit the amplified force in the same direction to the corresponding elastic part, thereby allowing the pulley to move adaptively with the deviation direction of the transmission belt. The present invention does not require expensive components such as sensors, main controllers, and pulley adjustment mechanisms. It can effectively prevent the deviation of the transmission belt and pulleys only through mechanical structures, eliminate the friction generated by their deviation, avoid dust generation, and increase the service life of the conveyor. It is suitable for the transmission of dust-sensitive products such as TopCon batteries.
