[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1, referring to Figures 1 to 9This is the first embodiment of the present invention. This embodiment provides a belt detection device that enables quick installation and removal of the driven pulley 502, facilitating observation of the pigment on the outer surface of the driven pulley 502 after belt detection. The device includes a frame 500, a drive pulley 501 and two sets of driven pulleys 502 mounted on the frame 500. A pigment sprayer 503 and a tensioner adjuster 504 are located on the frame 500 near the driven pulleys 502. The device also includes a mounting mechanism 100, through which the driven pulleys 502 are connected to the frame 500. The mounting mechanism 100 includes an inserter located inside the driven pulley 502. The frame 500 is provided with a sleeve 102 that is fitted with the insert 101. The sleeve 102 is provided with a locking member 103. The insert 101 is provided with a positioning member 104 that is fitted with the locking member 103. One end of the insert 101 is provided with a contact member 105. The frame 500 is also provided with a positioning mechanism 200. The positioning mechanism 200 includes a support member 201 provided in the sleeve 102. The support member 201 is provided with an offset member 202. The offset member 202 is provided with an elastic member 203. The sleeve 102 is provided with an expansion member 204 that is fitted with the elastic member 203. The contact member 105 is fitted with the expansion member 204.

[0031] In the process of testing belts, the present invention first places the belt to be tested on the driving pulley 501 and two sets of driven pulleys 502 to make the belt tension meet the experimental requirements. After the tension is adjusted, the tension wheel adjuster 504 is locked.

[0032] Next, the pigment sprayer 503 is turned on, and the pigment sprayer 503 sprays the pigment evenly onto the driven wheel 502. The motor is turned on, and the driving wheel 501 drives the belt to be tested. When the belt passes the driven wheel 502, only the part of the belt that is in contact with the driven wheel 502 will be contaminated with pigment. The parts of the belt that are not in contact with the driven wheel 502 will not be contaminated or will be contaminated with very little pigment. After completion, the belt is removed. By detecting whether each part of the belt is contaminated with pigment and the amount of pigment contaminated in each part of the belt, the actual contact between the belt and the driven wheel can be determined.

[0033] Meanwhile, the present invention can also change the tension of the belt by means of tension wheel adjuster 504. A dial indicator is provided on the frame 500 near the belt to be tested. The dial indicator head is kept in contact with the belt to be tested so as to detect the belt runout.

[0034] In summary, when the belt inspection is completed and it is necessary to observe or clean the paint on the belt, simply release the locking state of the insert 101 and the sleeve 102 by using the locking member 103. Then, the driven wheel 502 can be removed from the frame 500, and the driven wheel 502 can be cleaned. Similarly, after cleaning, the driven wheel 502 can be fixed by inserting the insert 101 into the sleeve 102 and using the locking member 103. At the same time, this device further improves the installation mechanism 100. When the insert 101 moves downward, it drives the abutment 105 to move. At this time, the abutment 105 cooperates with the expansion member 204 to position the insert 101.

[0035] Example 2, refer to Figures 1 to 9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an insert 101 for a belt detection device. The insert 101 includes an insert rod 101a disposed in the driven wheel 502. Limiting strips 101b are integrally formed on both sides of the outer wall of the insert rod 101a. The sleeve 102 includes a sleeve 102a installed on the upper end face of the frame 500. A stepped groove 102b is provided in the sleeve 102a. The stepped groove 102b is convex in shape. The convex structure provides a large space at the bottom end of the sleeve 102a, ensuring the positioning effect of the positioning mechanism 200 on the insert 101. Limiting grooves 102c are provided on both sides of the stepped groove 102b. The limiting strips 101b are slidably connected in the limiting grooves 102c. By forming limiting strips 101b on both sides of the outer wall of the insert rod 101a, the present invention ensures that the insert rod 101a will not change direction when moving, thus ensuring the stability of vertical movement.

[0036] Furthermore, the locking element 103 includes an annular edge 103a rotatably connected within the stepped groove 102b. The annular edge 103a is rotatably connected to the inside of the sleeve 102a via a bearing. An mounting groove 103b is provided on the upper end face of the annular edge 103a. A tension spring 103c is fixedly connected to the inner wall of the mounting groove 103b. The tension spring 103c is a carbon spring, which has high strength and is convenient for daily use. A wedge block 103d is fixedly connected to one end of the tension spring 103c. An arc-shaped block is provided on the outer wall of the sleeve 102a. The wedge block 103d has a hole 103e and a pull rod 103f fixedly connected to one end. The pull rod 103f is slidably connected in the arc-shaped hole 103e. The inner wall of the annular edge 103a is provided with an arc-shaped groove 103g. The upper end face of the wedge block 103d is arc-shaped, which ensures that when the insert 101 moves downward, the wedge block 103d is subjected to a squeezing force and moves outward. Furthermore, a tension spring 103c is connected to the wedge block 103d. In the initial state, the spring acts to position the displacement of the annular edge 103a.

[0037] The positioning component 104 includes a slot 104a on the outer wall of the insertion rod 101a. A limiting block 104b is also provided on the outer wall of the insertion rod 101a. The limiting block 104b is slidably connected in the arc groove 103g. The structure of the annular edge 103a is further defined by this device. Since the annular edge 103a is rotatably connected to the inner wall of the sleeve 102a, when the insertion rod 101a moves downward, the limiting block 104b fixedly connected to the outer wall is slidably connected in the arc groove 103g. Since the vertical displacement of the insertion rod 101a is inconvenient, the deflection force of the arc groove 103g drives the annular edge 103a to rotate until the wedge block 103d corresponds to the slot 104a.

[0038] The rest of the structure is the same as in Example 1.

[0039] When installing the driven wheel 502, the insertion rod 101a inside the driven wheel 502 first aligns with the sleeve 102a. At this time, the limiting strips 101b on both sides of the outer wall of the insertion rod 101a slide in the limiting groove 102c to ensure stability when the insertion rod 101a moves in the direction of the insertion rod 101a. The wedge block 103d is arc-shaped to ensure that when the insertion rod 101a moves downward, the wedge block 103d is subjected to the squeezing force and moves outward. The tension spring 103c deforms. When the limiting block 104b on the insertion rod 101a contacts the arc groove 103g, the deflection force of the arc groove 103g drives the annular edge 103a to rotate until the wedge block 103d aligns with the slot 104a. At this time, under the action of the tension spring 103c, the wedge block 103d is inserted into the slot 104a, thus fixing the position of the insertion rod 101a.

[0040] Example 3, referring to Figures 1 to 9 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an abutment member 105 for a belt detection device. The abutment member 105 includes an abutment plate 105a symmetrically fixed to the end of the insertion rod 101a. A locking block 105b is integrally formed at one end of the abutment plate 105a. A locking protrusion 105c is integrally formed on the locking block 105b. An abutment block 105d is fixedly connected to the inner side of the abutment plate 105a. The abutment block 105d has an abutment surface 105e.

[0041] This device further defines the structure of the insertion rod 101a. By symmetrically installing abutment plates 105a at the end of the insertion rod 101a, and forming a locking block 105b at the end of the abutment plate 105a, a locking protrusion 105c protrudes inward in the middle of the locking block 105b, ensuring that the abutment 105 cooperates with the expansion member 204 after moving downward. At the same time, a wedge-shaped abutment block 105d is formed on the inner side of the abutment plate 105a. The abutment block 105d is an inclined surface that abuts against the bending block 202d in the offset member 202, thereby driving the inclined rod 202b to move.

[0042] Furthermore, the support member 201 includes an annular plate 201a fixedly connected to the inner wall of the stepped groove 102b. An annular sleeve 201b is integrally formed inside the annular plate 201a. A support rod 201c is movably connected inside the annular sleeve 201b. A compression spring 201d is sleeved on the upper end of the support rod 201c. The compression spring 201d is a carbon spring with high strength. The compression spring 201d is located on the lower end face of the insertion rod 101a. The offset member 202 includes a through hole 202e provided in the annular sleeve 201b. The position of the support rod 201c corresponding to the through hole 202e is... An inclined hole 202a is provided, and an inclined rod 202b is movably connected in the inclined hole 202a. An auxiliary spring 202c is sleeved on one end of the inclined rod 202b that passes through the through hole 202e. A bending block 202d is integrally formed on one end of the inclined rod 202b, and an abutting block 105d abuts against the bending block 202d accordingly. A sliding edge 202f is integrally formed on the outer wall of the inclined rod 202b. The sliding edge 202f slides in the through hole 202e accordingly. Due to the action of the sliding edge 202f, the inclined rod 202b can only move in the horizontal direction.

[0043] This device further defines the structure of the annular plate 201a. The inner side of the annular plate 201a is hollow. The hollow shape facilitates the downward movement of the contact member 105 at the lower end of the insertion rod 101a. At the same time, an annular sleeve 201b is integrally formed in the middle. A support rod 201c moves vertically inside the annular sleeve 201b. The annular sleeve 201b and the support rod 201c are provided with an inclined hole 202a in the same direction. An inclined rod 202b is movably connected in the inclined hole 202a. At the same time, an auxiliary spring 202c is sleeved on one end of the inclined rod 202b. A bending block 202d is formed in the opposite direction of the inclined rod 202b. When the contact surface 105e contacts the bending block 202d, the inclined rod 202b is driven to move in the inclined hole 202a under pressure.

[0044] The elastic member 203 includes a hollow hole 203a within the support rod 201c. An elastic plate 203b is fixedly connected to the bottom of the inner wall of the hollow hole 203a. An extension plate 203c is formed on both sides of the upper end of the elastic plate 203b. A bifurcated groove 203d is provided in the extension plate 203c. The expansion member 204 includes slots 204a on both sides of the inner wall of the stepped groove 102b. Movable springs 204b are fixedly connected to the slots 204a respectively. An expansion plate 204c is provided in the movable springs 204b. A connecting plate 204d is fixedly connected to the outer wall of the expansion plate 204c. An integrally formed... An arc-shaped plate 204e is formed, and a slot 204f is provided in the arc-shaped plate 204e. The corresponding slot 105c is locked in the slot 204f. The expansion plates 204c on both sides are staggered with a first positioning strip 204g and a second positioning strip 204h. The expansion plates 204c on both sides are correspondingly provided with a first positioning groove 204i and a second positioning groove 204j. The first positioning strip 204g and the second positioning strip 204h are correspondingly inserted into the first positioning groove 204i and the second positioning groove 204j. The first positioning strip 204g and the second positioning strip 204h are located between two sets of extension plates 203c.

[0045] This device further defines the structure of the support rod 201c. Since the annular sleeve 201b and the support rod 201c are provided with inclined holes 202a, and inclined rods 202b are movably connected in the inclined holes 202a, after the inclined rods 202b are squeezed and move in an inclined direction, they drive the support rod 201c to move upward. Therefore, by providing a hollow hole 203a in the support rod 201c, and providing an expanded elastic member 203 at its bottom end, the elastic member 203 deforms due to the upward movement of the support rod 201c and the fixed position of the expansion member 204. At this time, the locking protrusion 105c is correspondingly locked in the locking groove 204f, thus completing the further locking of the support rod 201c and the insertion rod 101a.

[0046] The rest of the structure is the same as in Example 2.

[0047] During use, when the insertion rod 101a moves downward, the end contact plate 105a of the insertion rod 101a contacts the arc plate 204e. Under downward pressure, it drives the expansion plates 204c on both sides to move inward until the corresponding locking protrusion 105c is locked in the corresponding slot 204f. At the same time, as the insertion rod 101a moves downward, it drives the contact block 105d to contact the bending block 202d. Due to the action of the sliding edge 202f, the tilting rod 202b can only move horizontally. At this time, under the pressure of the inclined surface, it drives the tilting rod 202b to move in the tilting hole 202a until the bending block 202d contacts the annular sleeve 201b. When the outer surfaces are in contact, the support rod 201c moves upward as the tilting rod 202b moves, causing the first positioning strip 204g and the second positioning strip 204h to press against the elastic member 203. Thus, when the support rod 201c stops moving, the first positioning strip 204g and the second positioning strip 204h position the support rod 201c, and at this time, the locking protrusion 105c is correspondingly locked in the locking groove 204f, completing the locking of the support rod 201c. At this time, the position of the insertion rod 101a is not only locked by the installation mechanism 100, but also further reinforced by the positioning mechanism 200 to ensure the tightness of the connection between the insertion member 101 and the sleeve member 102.

The pull rod (103f) is slidably connected in the arc-shaped hole (103e), and an arc-shaped groove (103g) is provided on the inner wall of the annular edge (103a). The positioning component (104) includes a slot (104a) on the outer wall of the insertion rod (101a), and a limiting block (104b) is also provided on the outer wall of the insertion rod (101a). The wedge block (103d) is correspondingly inserted into the slot (104a), and the limiting block (104b) is correspondingly slidably connected in the arc groove (103g). The abutting member (105) includes abutting plates (105a) symmetrically arranged at the ends of the insert rod (101a). A locking block (105b) is provided at one end of the abutting plate (105a). The locking block (105b) is integrally formed with a locking protrusion (105c). An abutting block (105d) is provided on the inner side of the abutting plate (105a). The abutting block (105d) has an abutting surface (105e). When the insertion rod (101a) moves downward, the end contact plate (105a) of the insertion rod (101a) comes into contact with the arc plate (204e). Under the downward pressure, it drives the expansion plates (204c) on both sides to move inward until the corresponding locking protrusion (105c) is locked in the corresponding slot (204f). At the same time, as the insertion rod (101a) moves downward, it drives the contact block (105d) to come into contact with the bending block (202d). Due to the action of the sliding edge (202f), the tilting rod (202b) can only move horizontally. At this time, under the extrusion of the inclined surface, the tilting rod (202b) is driven into the inclined hole. (202a) moves inward until the bending block (202d) contacts the outer surface of the annular sleeve (201b). When the tilting rod (202b) moves, the support rod (201c) moves upward, causing the first positioning strip (204g) and the second positioning strip (204h) to press against the elastic element (203). Thus, when the support rod (201c) stops moving, the first positioning strip (204g) and the second positioning strip (204h) position the support rod (201c), and at this time, the locking protrusion (105c) is correspondingly locked in the locking groove (204f), completing the locking of the support rod (201c).
