Description

Technical Field

[0001] The utility model relates to a delayed conveying component for a film conveying mechanism. Background Art

[0002] The production process of the semi-finished product required for tire molding requires the use of a conveying mechanism and a receiving mechanism. The specific production process is: the conveying mechanism conveys the film to the receiving mechanism, the head end of the lining cloth on an I-shaped wheel of the receiving mechanism is bonded together with the head end of the film, and they are wound together on another empty I-shaped wheel of the receiving mechanism. After the winding is completed, a finished semi-finished product is formed.

[0003] Since the conveying mechanism is a long conveyor belt production line, after one round of winding operation is completed, the receiving mechanism located at the rear end of the conveying mechanism needs to be replaced in preparation for the next round of winding operation. This requires shutting down and pausing the conveying mechanism and production equipment first, waiting for the replacement of the receiving mechanism. However, such operation will result in inconsistent quality of semi-finished products formed by each round of winding, and even defective products will appear, resulting in material waste. In addition, the frequent opening and closing of large-scale production lines will also lead to increased energy and power consumption, and the equipment is prone to failure, which is not conducive to the mass production of semi-finished products. Utility Model Content

[0004] The utility model provides a delayed conveying component for a film conveying mechanism, which can effectively solve the above problem.

[0005] The utility model is achieved in this way:

[0006] A delayed conveying assembly for a film conveying mechanism, the delayed conveying assembly is arranged on a horizontal conveyor belt of the conveying mechanism; the horizontal conveyor belt is provided with a drop opening corresponding to the delayed conveying assembly, the drop opening is formed by two side plates of the horizontal conveyor belt, a front horizontal conveying part and a rear horizontal conveying part;

[0007] The delayed conveying assembly includes a sealing plate for opening and closing the vertical material port and a rotating cylinder; the sealing plate is hingedly matched between the two side plates of the horizontal conveyor belt, the cylinder end of the rotating cylinder is hingedly connected to the mounting plate below the horizontal conveyor belt, and the piston rod end is hingedly connected to the lower end of the sealing plate;

[0008] When the receiving mechanism located below the discharge port of the conveying mechanism changes material, the piston rod of the rotating cylinder retracts, actuating the sealing plate to flip downward to open the vertical material port, and the continuously conveyed film hangs down from the vertical material port to below the horizontal conveyor belt, so that the head end of the film is positioned at the discharge port of the horizontal conveyor belt.

[0009] As a further improvement, a distance measuring sensor for detecting the drooping height of the film is arranged below the horizontal conveyor belt and at the center of the alignment drooping opening.

[0010] As a further improvement, a photoelectric detector for identifying film breaks is installed under the horizontal conveyor belt. The photoelectric detector includes a photoelectric switch for emitting light and a reflective plate at the same horizontal position as the photoelectric switch and for receiving light. The photoelectric switch is installed under the horizontal conveying part behind the vertical material outlet, and the reflective plate is installed under the horizontal conveying part in front of the vertical material outlet.

[0011] As a further improvement, the lower end of the horizontal conveyor belt is fixedly connected to a plurality of upright posts, and the mounting plate is fixedly installed between two adjacent upright posts on the left and right sides.

[0012] The beneficial effects of the utility model are:

[0013] The present application sets a delayed conveying component on the conveyor belt structure. When the material receiving mechanism changes the material, the vertical material outlet is opened by the sealing plate, so that the continuously conveyed film first hangs down to the bottom of the horizontal conveyor belt, so as to achieve the effect of positioning the head end of the film at the discharge port of the horizontal conveyor belt. Therefore, the conveying structure of the present application does not need to be shut down and wait during operation, so that the quality of the semi-finished product formed by winding is stable, which is conducive to the mass production of semi-finished products.

[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1 to Figure 3 As shown, an efficient film continuous conveying mechanism includes a conveyor belt structure 10 for conveying film, a pair of film cutting components 20 arranged on the conveyor belt structure 10 and at least one delayed conveying component 30; the conveyor belt structure 10 includes a lifting conveyor belt 11 arranged upwardly inclined and a horizontal conveyor belt 12 fixedly connected to the top of the lifting conveyor belt 11, and a vertical material opening 101 corresponding to the delayed conveying component 30 is provided on the horizontal conveyor belt 12, and the delayed conveying component 30 includes a sealing plate 31 for opening and closing the vertical material opening 101; when the receiving mechanism 110 located below the discharge port 102 of the conveying mechanism 100 changes material, the sealing plate 31 opens the vertical material opening 101, and the continuously conveyed film hangs down from the vertical material opening 101 to below the horizontal conveyor belt 12, so that the head end of the film is to be positioned at the discharge port 102 of the horizontal conveyor belt 12.

[0035] The structures of the various components of the utility model are described below.

[0036] like Figure 1 to Figure 3 As shown, in this embodiment, the number of the vertical material outlets 101 is preferably set to two, and the horizontal conveyor belt 12 has a front horizontal conveying part 121 located at the front end of the vertical material outlet 101 and a rear horizontal conveying part 122 located at the rear end of the vertical material outlet 101. The vertical material outlet 101 is surrounded by the front horizontal conveying part 121, the rear horizontal conveying part 122 and two side panels 120, and the sealing plate 31 is hingedly matched between the two side panels 120.

[0037] like Figure 1 to Figure 4 As shown, the horizontal conveyor belt 12 is erected on the ground through a plurality of columns 123 fixed at the lower end, and a mounting plate 124 is fixed between two adjacent columns 123 on the left and right; the delayed conveying assembly 30 also includes a rotating cylinder 32, the cylinder body end of the rotating cylinder 32 is hinged to the mounting plate 124, and the piston rod end is hinged to the lower end of the sealing plate 31; the piston rod of the rotating cylinder 32 retracts, actuating the sealing plate 31 to flip downward to open the vertical material port 101, and the piston rod extends, actuating the sealing plate 31 to flip upward to close the vertical material port 101. It should be noted here that when the vertical material port 101 is closed, the surface of the sealing plate 31 is flush with the surface of the horizontal conveyor belt 12, so as to stably and continuously convey the film.

[0038] like Figure 2 As shown, a distance sensor 50 for detecting the drooping height of the film is provided below the horizontal conveyor belt 12 and at the center of the aligned vertical material outlet 101. When the distance sensor 50 identifies that the drooping height of the film reaches the lower limit height H, the conveying speed of the front horizontal conveying part 121 is greater than the conveying speed of the rear horizontal conveying part 122, so as to pull the drooping film back to the horizontal conveying posture; when the distance sensor 50 identifies that the drooping height of the film returns to the upper limit height h, the rotating cylinder 32 is flipped upward to close the vertical material outlet 101. It should be noted here that the conveying speed of the conveying part is achieved by controlling the motor speed of the conveying part. This part of the content is the prior art, so it will not be repeated here.

[0039] like Figure 4As shown, a photoelectric detector 40 for identifying film breaks is installed below the horizontal conveyor belt 12. The photoelectric detector 40 includes a photoelectric switch 41 for emitting light and a reflector 42 at the same horizontal position as the photoelectric switch 41 and for receiving light. The photoelectric switch 41 is installed below the horizontal conveying part 122 located behind the vertical material outlet 101, and the reflector 42 is installed below the horizontal conveying part 121 located in front of the vertical material outlet 101. When the film is dropped (i.e., the film is broken at the vertical material outlet 101), the distance sensor 50 located below the horizontal conveyor belt 12 cannot identify the drooping height of the film, and the light emitted by the photoelectric detection switch cannot be received by the reflector 42 due to being blocked by the film, so as to identify that the film is in a dropped state. At this time, the conveying mechanism 100 should be closed, and the film should be adjusted and processed manually.

[0040] like Figure 5 to Figure 7 As shown, a protective cover 125 is provided near the discharge port 102 of the horizontal conveyor belt 12. The protective cover 125 includes a vertical plate 1251 fixedly connected to the upper surface of the two side plates 120 of the horizontal conveyor belt 12 and a top plate 1252 installed on the top of the two vertical plates 1251; the cutting assembly 20 includes a cutting knife 21, a sprocket transmission group and a cutting knife motor 25 for controlling the cutting knife 21 to cut the film, and the cutting knife motor 25 is fixedly mounted on the side plate 120; the cutting knife 21 rotates The cutter 21 is installed between the two cutter supports 13 on the conveyor belt structure 10, and a material passing cavity 103 is formed between the cutter 21 and the horizontal conveyor belt 12 for allowing the rubber material to extend out of the discharge port 102. The sprocket transmission group includes a first sprocket 22, a second sprocket 23 and a connecting chain 24 sleeved between the first sprocket 22 and the second sprocket 23. The first sprocket 22 is mounted on the rotating shaft of the cutter 21, and the second sprocket 23 is fixedly connected to the output shaft of the cutter motor 25.

[0041] like Figure 5 to Figure 7 As shown, a meter counter 60 is installed on the side plate 120 of the horizontal conveyor belt 12 at the rear end of the cutting assembly 20. When the meter counter 60 recognizes that the length of the conveyed film reaches the preset winding length, the feeding conveyor 126 and the receiving conveyor 127 stop conveying, the receiving mechanism 110 stops winding and receiving the material, and the cutter motor 25 controls the second sprocket 23 to rotate to drive the first sprocket 22 to drive the cutter 21 to rotate and lower the knife to complete the cutting of the film. It should be noted here that since the film is made of soft material, this embodiment preferably uses a heating knife as the cutter 21. Such a design can make it easier to cut the film.

[0042] like Figure 5 to Figure 7As shown, a receiving conveying part 127 at the front end and a feeding conveying part 126 at the rear end are arranged at intervals at the feeding cavity 103. The receiving conveying part 127 includes a receiving transmission roller 1271 rotatably arranged between the two cutting knife supports 13 and located at the front end of the feeding cavity 103. The feeding conveying part 126 includes a feeding transmission roller 1261 rotatably arranged between the two cutting knife supports 13 and located at the rear end of the feeding cavity 103. A receiving motor 203 for controlling the rotation of the receiving transmission roller 1271 is installed on one of the side plates 120. The output shaft of the receiving motor 203 is fixedly connected to the receiving transmission roller 1271. The cutting assembly 20 also includes a clutch 27 and a receiving transmission roller 1261 arranged on the other side. A sprocket 28, a feeding sprocket 29, and a transmission chain 201 arranged between the receiving sprocket 28 and the feeding sprocket 29, and the feeding sprocket 29 is fixedly mounted on the shaft end of the feeding transmission roller 1261; the clutch 27 has a fixed part 271 and a rotating part 272 rotatably connected to the fixed part 271, the fixed part 271 of the clutch 27 is installed on the shaft end of the receiving transmission roller 1271, and the receiving sprocket 28 is installed on the rotating part 272 of the clutch 27, and the clutch 27 controls the engagement and separation of the receiving sprocket 28 and the receiving transmission roller 1271 through the engagement and separation of the fixed part 271 and the rotating part 272; it should be noted here that the engagement and separation of the clutch 27 is a prior art, so it will not be repeated here.

[0043] When the film is conveyed normally, the clutch 27 is in the starting and attracted state, and the receiving drive roller 1271 can synchronously drive the receiving sprocket 28 to rotate, so as to drive the feeding drive roller to rotate together, thereby realizing an efficient conveying process in which one receiving motor 203 drives two conveying parts to run together; when the film is cut, the clutch 27 is in the closing and separation state, and the receiving motor 203 can only drive the receiving drive roller 1271 to rotate, and at this time the speed of the receiving motor 203 is greater than the normal conveying speed of the film, thereby accelerating the cutting of the film to be quickly discharged from the discharge port 102 and wound up by the receiving mechanism 110. During this process, the feeding conveyor 126 stops running, and with the help of the delayed conveying component 30, the head end of the conveyed film is positioned at the feeding cavity 103.

[0044] like Figure 5 to Figure 7As shown, a transition roller 128 located below the material transfer cavity 103 is rotatably arranged between the two side plates 120, a transition sprocket 1281 is arranged at the rotating shaft of the transition roller 128, an auxiliary sprocket 291 is fixedly arranged on the end face of the feeding sprocket 29, and a linkage chain 202 is sleeved between the auxiliary sprocket 291 and the transition sprocket 1281; with such a design, when the material receiving sprocket 28 drives the feeding sprocket 29 to rotate, the auxiliary sprocket 291 on the feeding sprocket 29 can also synchronously drive the transition sprocket 1281 to rotate, so as to realize a material receiving motor 203 synchronously driving the rotation operation of the feeding conveying part 126, the material receiving conveying part 127 and the transition roller 128, thereby improving the stability of the film conveying process.

[0045] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
