Description

Technical Field

[0001] The utility model relates to the technical field of molding machines, in particular to a feeding device and a molding machine. Background Art

[0002] In the prior art, the inner lining layer feeding method of the forming machine is to guide the inner lining layer away and then convey the entire inner lining layer to the front template through a conveyor belt. There is a material storage arc between the middle feeding template and the front feeding template (the function is to prevent the inner lining layer from stretching during the bonding process). The front feeding template is a powered Furley wheel assembly structure. When the inner lining layer is bonded to the drum, the front feeding template is extended as a whole through the cylinder, the material storage arc is enlarged, and the inner lining layer is manually bonded and cut and overlapped, and the front feeding template is returned. However, the current feeding method has the following problems:

[0003] 1. The inner lining is conveyed in such a way that the whole sheet is pulled onto the front bonding drum. When the front template is extended, the storage arc will supplement the distance of the template extension. If automatic fixed-length cutting is added to the middle template, the single inner lining after cutting will not be able to be transported across the storage arc to the front template. Therefore, it is currently not possible to add a fixed-length cutting device to the middle feeding template, and it can only be cut manually.

[0004] 2. Since the inner lining layer is overlapped and manually cut, the length inaccuracy will be caused; the thickness of the inner lining layer is about 6mm, and there are a lot of bubbles between the overlapped joint and the fiber cord that is bonded again, which cannot be discharged, affecting the product process and resulting in uneven product quality.

[0005] 3. When the front template is fed to the laminating drum for laminating, the front template as a whole approaches the laminating drum. After the end of the front template close to the laminating drum reaches the laminating strand, laminating is performed. After the front template is extended as a whole, a gap is formed between the other end of the front template and the middle template. Because the length of a single lining layer is about 3 meters, and the space length of the front template is only about 1.5 meters, when the lining layer is cut to a fixed length and transported to the front template, about 1.5 meters will be on the middle template. When the front template is extended, if there is a storage gap at the non-laminating drum end, the lining layer is easy to fall or fold in the gap between the middle template and the front template during transportation.

[0006] Therefore, the feeding efficiency of the molding machine feeding device in the prior art is relatively poor.

[0007] Therefore, the prior art needs to be further developed. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] According to an embodiment of the present invention, a feeding device is provided. Figures 1 to 5 , including: a fixed base 1; a movable bracket 2, the movable bracket 2 is movably connected to the fixed base 1; a telescopic cylinder 3, the telescopic cylinder 3 is fixedly arranged on the fixed base 1, and the piston rod 311 of the telescopic cylinder 3 is connected to the movable bracket 2; a first guide roller 11 is installed at one end of the fixed base 1, a second guide roller 12 is installed at the other end of the fixed base 1, and a third guide roller 21 is installed at one end of the movable bracket 2 close to the second guide roller 12, and a conveyor belt is wound around the first guide roller 11, the second guide roller 12 and the third guide roller 21, and the conveying length of the conveyor belt can be set variably.

[0032] Specifically, the movable bracket 2 can be controlled to slide relative to the fixed base 1 through the telescopic cylinder 3, thereby changing the relative position of the movable bracket 2 on the fixed base 1. The conveying length of the conveyor belt can be changed as the movable bracket 2 moves, so that the length of the conveyor belt is increased or reset. When the telescopic cylinder is extended, the conveying length increases, thereby delivering the material to the designated location, thereby completing the feeding. When the telescopic cylinder is retracted, the conveying length becomes smaller and returns to the initial length.

[0033] The feeding device of this embodiment is applied to the front feeding template of the molding machine. When the feeding device is extended to mate with the bonding drum, the fixed base 1 remains stationary, and the conveyor belt is extended to increase the conveying length of the conveyor belt. The material is transferred by controlling the elongation of the conveyor belt to avoid a gap between the feeding device and the middle template. The feeding device is connected to the middle template to achieve continuous and automatic feeding of materials, solve the problem of material folding or falling, improve the material conveying efficiency, and solve the technical problem of poor feeding efficiency of the feeding device of the molding machine in the related art.

[0034] In the feeding device of this embodiment, see Figure 3 and Figure 4 The movable bracket 2 is provided with a fourth guide roller 22, and the conveyor belt is sequentially connected with the first guide roller 11, the second guide roller 12, the fourth guide roller 22 and the third guide roller 21. By providing the fourth guide roller 22, the conveyor belt is guided in a reverse direction and the conveyor belt is tensioned and adjusted to prevent deviation.

[0035] Specifically, the fourth guide roller 22 is arranged between the second guide roller 12 and the third guide roller 21. The fourth guide roller 22 is located at the bottom of the movable bracket 2. The fourth guide roller 22 is spaced a certain distance from the third guide roller 21. This distance determines the length by which the conveyor belt can be extended.

[0036] See also Figure 4 , Figure 4 It is a structural diagram of the feeding device in the extended state. During the extending process of the movable bracket 2, since the fourth guide roller 22 and the third guide roller 21 are installed on the movable bracket 2 at the same time, the fourth guide roller 22 will compensate for the displacement of the third guide roller 21 during the movement. Therefore, only the conveyor belt between the third guide roller 21 and the second guide roller 12 is moving, and the upper surface of the feeding device is stationary. During the extending process, the material supported on the upper surface of the feeding device and the conveyor belt will not produce relative displacement, thereby avoiding pulling and friction of the material.

[0037] The feeding device of this embodiment is applied to the front feeding template of the molding machine. Compared with the traditional feeding device, the upper surface of the conveyor belt is stationary while the conveyor belt is extended, the design of the material storage arc can be eliminated, and the gap between the feeding device and the middle template is eliminated, thereby realizing continuous feeding, preparation and continuous bonding.

[0038] When there is no gap between the front template and the middle template, a single piece of material can be continuously conveyed, so that an automatic fixed-length cutting device can be added to the middle template. Through the feeding device of this embodiment, the feeding gap between the templates is eliminated, and the material can be continuously conveyed, which can solve the problem that the inner lining of the farmer's tire cannot be cut to a fixed length. After automatic fixed-length cutting is achieved, the cutting surface has a cutter that can adjust the angle of about 20° to cut out a slope surface. The slope surfaces are directly connected, which is called slope connection. The thickness after slope connection is the original thickness of the material, which solves the problem of long-term overlap in the joint process of the inner lining of the farmer's tire, realizes the slope connection between the inner lining layers, and improves the product process and quality.

[0039] It can be understood that the first guide roller 11, the second guide roller 12, the fourth guide roller 22 and the third guide roller 21 each include multiple rollers, and the width of the guide rollers can be flexibly adjusted. The width of the first guide roller 11, the second guide roller 12, the fourth guide roller 22 and the third guide roller 21 can be freely determined according to the width of the template and the material.

[0040] In the feeding device of this embodiment, see Figure 1 The feeding device includes: a slide rail 41, which is fixedly arranged on the movable bracket 2; a slider 42, which is fixedly arranged on the fixed base 1, and the slider 42 is slidably connected to the slide rail 41. By setting the slide rail 41 and the slider 42, the direction of the movable bracket 2 is guided during the sliding process.

[0041] In the feeding device of this embodiment, see Figure 1 The fixed base 1 includes a first fixed plate 13 and a second fixed plate 14 arranged opposite to each other, and a slider 42 is installed on each of the first fixed plate 13 and the second fixed plate 14; the slide rail 41 includes a first slide rail 411 and a second slide rail 412 arranged opposite to each other, and the first slide rail 411 and the second slide rail 412 are installed on both sides of the movable bracket 2. Through the above arrangement, the movable bracket 2 is fixed on the fixed base 1.

[0042] Specifically, the second guide roller 12 and the third guide roller 21 are arranged at intervals, the second guide roller 12 is located below the third guide roller 21, and both ends of the rotating shaft of the second guide roller 12 are respectively fixed on the first fixing plate 13 and the second fixing plate 14.

[0043] In the feeding device of this embodiment, see Figure 1The feeding device includes: a driving component, which is connected to the rotating shaft of the first guide roller 11 to drive the conveyor belt to rotate; a first mounting seat 51 and a second mounting seat 52 are arranged at intervals, and the first mounting seat 51 and the second mounting seat 52 are movably connected to both ends of the rotating shaft of the first guide roller 11, and the first mounting seat 51 and the second mounting seat 52 are used to fix the first guide roller 11. By setting the driving component to drive the conveyor belt to rotate, the conveying function of the conveyor belt is realized; by setting the first mounting seat 51 and the second mounting seat 52, the feeding device can be installed on the molding machine.

[0044] Preferably, the driving component includes a motor and a sprocket to drive the rotating shaft of the first guide roller 11 to rotate.

[0045] In the feeding device of this embodiment, see Figure 1 The feeding device includes a first fixed seat 61 and a second fixed seat 62 which are inserted into the rotating shaft of the first guide roller 11. The first fixed seat 61 is fixedly connected to the first fixed plate 13, and the second fixed seat 62 is fixedly connected to the second fixed plate 14. By providing the first fixed seat 61 and the second fixed seat 62, the first guide roller 11 is connected to the first fixed plate 13 and the second fixed plate 14 as a whole, so that the feeding device can adjust the angle around the first guide roller 11.

[0046] In the feeding device of this embodiment, see Figure 1 The fixed base 1 includes a third fixed plate 15, and the two ends of the third fixed plate 15 are respectively fixedly connected to the first fixed plate 13 and the second fixed plate 14; the third fixed plate 15 is movably connected to the telescopic cylinder 3. By providing the third fixed plate 15, the first guide roller 11 can be locked to prevent the first fixed seat 61 and the second fixed seat 62 from moving in series.

[0047] In the feeding device of this embodiment, see Figure 5 The fixed base 1 includes: a hanging seat 7, which is fixedly connected to the fixed base 1; an adjusting device 71, which is telescopically arranged, and the protruding end of the adjusting device 71 is connected to the hanging seat 7, so that the feeding device rotates around the first guide roller 11.

[0048] The hanging seat is connected to the equipment frame by using the adjusting device 71, and the angle of the feeding device can be adjusted by adjusting the adjusting device 71.

[0049] Preferably, the adjusting device 71 is a basket bolt, and a cylinder may also be installed to enable the feeding device to swing up and down with the first guide roller 11 as the axis.

[0050] In the feeding device of this embodiment, see Figure 1The telescopic cylinder 3 includes a first telescopic cylinder 31 and a second telescopic cylinder 32 which are arranged at intervals. The first telescopic cylinder 31 and the second telescopic cylinder 32 are respectively arranged on both sides of the conveyor belt. The piston rods of the first telescopic cylinder 31 and the second telescopic cylinder 32 are movably connected to the movable bracket 2. By arranging two telescopic cylinders, the stability of the movement of the movable bracket 2 is increased and the extension efficiency is improved.

[0051] Specifically, the two telescopic cylinders are equipped with one-way exhaust throttle valves for adjusting the extension and return speed of the telescopic cylinders; a magnetic detection switch is installed on the outer body of the telescopic cylinder to detect the extension and return state of the telescopic cylinder and provide a PLC feedback signal instruction.

[0052] Specifically, the piston rods of the first telescopic cylinder 31 and the second telescopic cylinder 32 are both hinged to the movable bracket 2 , and the first telescopic cylinder 31 and the second telescopic cylinder 32 are hinged to the third fixed plate 15 .

[0053] In the molding machine of this embodiment, see Figure 5 The molding machine includes a feeding device, which is the above-mentioned feeding device; the feeding device is used to transport the material to the bonding drum 10 of the molding machine.

[0054] The feeding device of this embodiment is applied to the front feeding template of the molding machine, and the feeding process is as follows:

[0055] When the materials are bonded on the bonding drum, the movable bracket 2 automatically returns, and the next cycle starts as follows:

[0056] 1. After the movable bracket 2 returns, the telescopic cylinder 3 detects that the telescopic cylinder 3 is in the return state and feeds back the signal to the PLC. The PLC gives a material preparation instruction. At this time, the middle template starts to convey the material forward. At the same time, the conveyor belt also starts to rotate. When the material is conveyed to the specified position of the feeding device, the photoelectric detection switch installed at the specified position will detect it. After the switch detects it, it will feed back to the PLC to stop conveying forward. The material preparation is completed and wait for extension and bonding.

[0057] 2. When the equipment runs to the step that requires bonding, an operator confirms the execution of the bonding step on the upper computer. After confirmation, the PLC outputs the bonding instruction, controls the solenoid valve to open and supply pressure to the telescopic cylinder 3, and the movable bracket 2 of the feeding device extends. After the extension, the magnetic detection switch on the telescopic cylinder 3 detects the position and feedbacks the signal to the PLC. The PLC outputs the solenoid valve closing signal and the rotation instruction of the conveyor belt and the bonding drum. This instruction requires the conveyor belt to transport the material to the overlapping part of the bonding drum, which is identified by the rotation angle of the bonding drum (on-site debugging is required to determine how many degrees of rotation can make the material and the bonding drum overlap perfectly. After debugging the angle, write the angle value into the program).

[0058] 3. After the material is overlapped on the bonding drum, the bonding drum rotates 360°, and the conveying speed of the conveyor belt is consistent with the rotation line speed of the bonding drum to complete the bonding. At this time, the photoelectric detection switch on the feeding device detects that the material bonding is completed and feeds the signal back to the PLC. The PLC outputs the return command of the movable bracket 2 to the solenoid valve. The solenoid valve opens and supplies pressure to the telescopic cylinder 3, and the movable bracket 2 returns. After returning, the next cycle is automatically executed, and it repeats over and over again.

[0059] The feeding device of this embodiment provides a fixed single-belt retractable feeding template, which can be widely used in OTR, TBR, PCR and other types of molding machines that require retractable feeding positions. The main drive shaft of this template is fixed, and only the sliding unit can be retracted. While retracting, the conveyor belt on the upper surface of the template is stationary. Compared with the front feeding template with an old structure, it can solve the problems of continuous feeding of a single piece, preventing it from falling, and continuous bonding.
