Description

Technical Field

[0001] The utility model relates to a material receiving roller brake release component for a material receiving trolley. Background Art

[0002] During the tire manufacturing process, various semi-finished films required for molding need to be wound on the I-shaped wheel assembly after the semi-finished product production process. The film winding and receiving process, such as Fig.17 As shown, the process generally includes the following steps: placing the I-wheel assembly below the discharge port of a conveying mechanism for conveying film, winding a pad cloth on the front I-wheel of the I-wheel assembly, bonding the material head end of the pad cloth to the material head end of the film and winding them together on the rear I-wheel of the I-wheel assembly to complete a winding and receiving operation.

[0003] When the I-shaped wheel group is transported to the bottom of the discharge port of the conveying mechanism, the front and rear I-shaped wheels are prone to relative rotation. The head end of the film has not yet had time to bond with the head end of the pad cloth, and the head end of the pad cloth has been wound on the rear I-shaped wheel first, that is, the head end is a single layer of pad cloth and the tail end is a single layer of film, resulting in the quality of the semi-finished product at both ends not meeting the production requirements of the finished product, which is not conducive to the mass production of semi-finished products; furthermore, after the winding is completed and during the transportation of the I-shaped wheel group unloading, the two I-shaped wheels may rotate relative to each other, causing the semi-finished product rolls to spread out.

A clutch control mechanism 50 is arranged on the sliding base 231. The clutch control mechanism 50 includes a first clutch assembly 51, and the clutch assembly includes a first transmission shaft 514, a first clutch 513, a first chassis 511 and a first cylinder 512. The first transmission shaft 514 is rotatably arranged on the sliding base 231 through a bearing. The first clutch 513 has a fixed portion and A rotating part that rotates with the fixed part, the fixed part is fixedly installed on the outer side of the first transmission shaft 514, and the first front sprocket 232 and the first rear sprocket 234 are fixedly connected to the rotating part; the first chassis 511 is installed at the end of the first transmission shaft 514 and the end face of the first chassis 511 has a first plug-in column 5111 that is plugged into the first plug-in hole 21121, and the first cylinder 512 is used to drive the first chassis 511 to slide axially along the first transmission shaft 514, so that the first plug-in column 5111 on the first chassis 511 is plugged into the first plug-in hole 21121, so as to synchronously drive the rotating shaft 2111 to rotate and drive the first I-shaped wheel group 211 to perform a winding operation.

[0056] It should be noted here that a spline sleeve (not shown) is installed on the first transmission shaft 514 to which the first chassis 511 can be mounted. With this design, the first chassis 511 can not only slide axially on the first transmission shaft 514, but can also be driven by the first transmission shaft 514 to rotate synchronously.

[0057] like Figures 9 to 15 As shown, when the first I-shaped wheel assembly 211 is used for winding operation, the first cylinder 512 pushes the first chassis 511 to extend, and the first plug-in column 5111 on the first chassis 511 is plugged into the first plug-in hole 21121 on the first top plate 2112, so that the first front sprocket 232 and the first rear sprocket 234 can be driven to rotate by the rotating shaft 2111 to drive the front I-shaped wheel 201 and the rear I-shaped wheel 202 of the first I-shaped wheel assembly 211 to rotate synchronously.

[0058] like Figures 9 to 15As shown, a driving sprocket 2121 and a driven sprocket 2122 are arranged at intervals on the end surfaces of the front I-shaped wheel 201 and the rear I-shaped wheel 202 of the second I-shaped wheel group 212 away from the first I-shaped wheel group 211, and a synchronous chain 2123 is sleeved between the driving sprocket 2121 and the driven sprocket 2122 to drive the two to rotate synchronously; the driven sprocket 2122 is fixedly mounted at the rotation center of the front I-shaped wheel 201 and the rear I-shaped wheel 202 of the first I-shaped wheel group 211, and the driven sprocket 2122 is rotationally matched with the rotating shaft 2111 through a bearing; a second top plate 2124 is fixedly mounted at the rotation center of the driven sprocket 2122, which is axially aligned with the second front sprocket 233 and the second rear sprocket 235 on the sliding base 231, and the second top plate 2124 has a second insertion hole 21241.

The second transmission shaft 524 is rotatably arranged on the sliding base 231 through a bearing. The second clutch 523 has a fixed portion and a rotating portion rotatably matched with the fixed portion. The fixed portion is fixedly mounted on the outer side of the second transmission shaft 524, and the second front sprocket 233 and the second rear sprocket 235 are fixed on the rotating portion; the second chassis 521 is mounted on the shaft end of the second transmission shaft 524 and the end face of the second chassis 521 has a second plug-in column 5211 plugged into the second plug-in hole 21241, and the second cylinder 522 is used to drive the second chassis 521 to slide axially along the second transmission shaft 524.

[0060] It should be noted here that a spline sleeve (not shown) is installed on the second transmission shaft 524 to which the second chassis 521 can be mounted. With this design, the second chassis 521 can not only slide axially on the second transmission shaft 524, but can also be driven by the second transmission shaft 524 to rotate synchronously.

[0061] When the second I-wheel assembly 212 is used for winding operation, the second cylinder 522 pushes the second chassis 521 to extend, and the second plug-in column 5211 on the second chassis 521 is plugged into the second plug-in hole 21241 on the second top plate 2124, so as to drive the driving sprocket 2121, the synchronous chain 2123 and the driven sprocket 2122 to drive the front I-wheel 201 and the rear I-wheel 202 of the second I-wheel assembly 212 to rotate synchronously.

[0062] It should be noted here that during the above process, the first clutch assembly 51 is closed, that is, when the second I-shaped wheel group 212 is in winding operation, the first I-shaped wheel group 211 does not rotate, and when the driven sprocket 2122 drives the front I-shaped wheel 201 and the rear I-shaped wheel 202 of the second I-shaped wheel group 212 to rotate, the driven sprocket 2122 idles relative to the rotating shaft 2111 of the front I-shaped wheel 201 and the rear I-shaped wheel 202 of the first I-shaped wheel group 211, so as to realize a driving unit 23 (that is, a motor 236) to drive the first I-shaped wheel group 211 and the second I-shaped wheel group 212 to rotate respectively, so that the two I-shaped wheel groups of the material receiving trolley 21 have the efficient winding characteristics of "one replacement and one use".

[0063] When the second I-wheel assembly 212 is used for winding operation, the second cylinder 522 pushes the second chassis 521 to extend, and the second plug-in column 5211 on the second chassis 521 is plugged into the second plug-in hole 21241 on the second top plate 2124, so as to drive the driving sprocket 2121, the synchronous chain 2123 and the driven sprocket 2122 to drive the front I-wheel 201 and the rear I-wheel 202 of the second I-wheel assembly 212 to rotate synchronously.

[0064] It should be noted here that during the above process, the first clutch 51 is in a pressure-released separation state, that is, when the second I-shaped wheel group 212 is in a winding operation, the first I-shaped wheel group 211 does not rotate, and when the driven sprocket 2122 drives the front I-shaped wheel 201 and the rear I-shaped wheel 202 of the second I-shaped wheel group 212 to rotate, the driven sprocket 2122 idles relative to the rotating shaft 2111 of the front I-shaped wheel 201 and the rear I-shaped wheel 202 of the first I-shaped wheel group 211, so as to realize a driving unit 23 (i.e., a motor 236) to drive the first I-shaped wheel group 211 and the second I-shaped wheel group 212 to rotate respectively, so that the two I-shaped wheel groups of the material receiving trolley 21 have the efficient winding characteristics of "one replacement and one use".

[0065] like Figure 1 to Figure 5 , Figure 7 As shown, the bottom of the material receiving trolley 21 has two spaced-apart slide rails 217, the sliding base 22 includes two spaced-apart side plates 223, and a plurality of cross bars 225 are spaced-apart between the two side plates 223 of the sliding base 22; a plurality of side sliding rollers 2231 are spaced-apart and rotatably arranged on the outer side surfaces of the two side plates 223, and when the material receiving trolley 21 is pushed in from above the sliding base 22, the side sliding rollers 2231 roll in cooperation with the bottom end of the slide rails 217 to reduce the friction resistance between the sliding base 22 and the material receiving trolley 21 when the material receiving trolley 21 is placed, thereby achieving the effect of saving effort and facilitating installation.

[0066] like Figure 1 to Figure 3 and Figure 7As shown, two center guide plates 213 are arranged at intervals in the middle of the bottom surface of the front end of the material receiving trolley 21, and a downward-opening guide groove 2131 is formed between the two center guide plates 213 on the bottom surface of the material receiving trolley 21, and a supporting plate 224 is extended to form on the rear end surface of the sliding base 22, and a plurality of center guide rollers 2241 are rotatably arranged on the top surface of the supporting plate 224, and the axes of the center guide rollers 2241 and the side sliding rollers 2231 are perpendicular to each other; when the material receiving trolley 21 is pushed into the top of the sliding base 22, the center guide rollers 2241 roll and fit in the center guide grooves 2131 to further reduce the friction resistance between the sliding base 22 and the material receiving trolley 21 when the material receiving trolley 21 is pushed, and through the design of the center guide rollers 2241, the material receiving trolley 21 can also be pushed into the sliding base 22 in a centered manner, so that it can be subsequently pushed into a preset installation position.

[0067] like Figure 7 As shown, two inclined transition plates 216 are formed at the front and rear ends of the two center guide plates 213. The two transition plates 216 located on different center guide plates 213 are in a flared shape away from the center guide plate 213, and the center guide roller 2241 slides into the center guide groove 2131 along the inner side of the transition plate 216. Such a design allows the rear end of the material receiving trolley 21 to be pushed into the preset installation position in a posture aligned with the sliding base 22 when the material receiving trolley 21 is pushed in, and the center guide roller 2241 can also slide out of the outlet groove 2131 more easily when the material receiving trolley 21 is pushed out, making the unloading process of the material receiving trolley 21 more convenient and labor-saving.

[0068] like Figure 2 , Figure 3 and Figure 6 As shown, the material receiving device also includes a positioning assembly 60 for locking the material receiving trolley 21 when the material receiving trolley 21 is pushed into the preset installation position. The positioning assembly 60 includes a limit fork plate 61, a limit cylinder 62 and a linkage rod 63 installed below the sliding base 22. The limit fork plate 61 is installed on the inner wall of the cross bar 225 at the front end through an axis rotation. The cross bar 225 at the front end and the two side plates 223 are enclosed to form a limit fork plate in a horizontal state. The fork plate 61 makes way for the avoidance cavity 226; one end of the linkage rod 63 is hinged to the end of the piston rod of the limiting cylinder 62, and the other end is fixedly connected to the rotation center of the limiting fork plate 61; when the material receiving trolley 21 is located at the preset installation position, the piston rod of the limiting cylinder 62 retracts and drives the limiting fork plate 61 through the linkage rod 63, swinging from a horizontal state to a vertical state in contact with the inner wall of the frame rod 214 at the front end of the material receiving trolley 21, so as to lock the material receiving trolley 21 in the preset installation position.

[0069] It should be noted here that when the material receiving trolley 21 is pushed into the preset installation position of the sliding base 22, the pulley 215 below the material receiving trolley 21 is spaced from the ground, so that the material receiving trolley 21 can avoid the material changing track 10, so as to avoid the pulley 215 of the material receiving trolley 21 being blocked by the material changing track 10, thereby preventing the material receiving assembly 20 from being able to slide freely on the material changing track 10.

[0070] like Figure 2 and 6 As shown, a position detection assembly 30 is provided on the top surface of the front end of the sliding base 22, and the position detection assembly 30 includes a proximity switch 32, a spring shaft rod 31 provided at the front end of the proximity switch 32, and a detection block (not shown in the figure) actuated by the spring shaft rod 31 to move forward and backward; when the material receiving trolley 21 is pushed onto the sliding base 22, the frame rod 214 of the material receiving trolley 21 pushes the spring shaft rod 31 to withdraw, and the spring shaft rod 31 pushes the detection block to move forward, and the proximity switch 32 detects the movement of the detection block, thereby detecting whether the material receiving trolley 21 is pushed into the preset installation position; after the material receiving trolley 21 is pushed out from the sliding base 22, the spring shaft rod 31 is reset to the initial state, and the proximity switch 32 cannot detect the detection block.

[0071] like Figure 2 and 6 As shown, an ejection cylinder 40 is provided on the top surface of the front end of the sliding base 22, and the piston rod of the ejection cylinder 40 is in a relative position to the frame rod 214 at the front end of the material receiving trolley 21. When the two I-shaped wheel groups on the material receiving trolley 21 have completed winding, the piston rod of the ejection cylinder 40 extends to push the material receiving trolley 21 to retreat as a whole and be pushed out from the top of the sliding base 22, so that the unloading process of the material receiving trolley 21 is more convenient and labor-saving.

[0072] like Figure 5 , Figure 7 and Fig.14 , Fig.15 As shown, a brake release assembly 90 is provided between the front I-shaped wheel 201 and the rear I-shaped wheel 202 of the first I-shaped wheel group 211 and between the front I-shaped wheel 201 and the rear I-shaped wheel 202 of the second I-shaped wheel group 212. The brake release assembly includes a base 91 installed on the material receiving trolley 21, and brake pads 92 rotatably connected to both sides of the base 91 and facing the circumference of the inner disk 210 of the front I-shaped wheel 201 and the rear I-shaped wheel 202. The brake release assembly also includes a locking structure 93 and a releasing structure 94; the locking structure 93 can lock the brake pads 92 in a state of contact with the circumference of the inner disk 210 to limit the rotation of the front I-shaped wheel 201 and the rear I-shaped wheel 202; when the material receiving trolley 21 is pushed into the preset installation position, the releasing structure 94 can control the brake pads 92 to swing to disengage from the inner disk 210, so that the two I-shaped wheel groups rotate to perform the winding operation.
