Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a feeding guide device for plastic slitting equipment. Background Technology

[0002] In the plastics processing industry, plastic slitting equipment is one of the key pieces of equipment in the production process. It is mainly used to cut plastic raw materials into strips of the required width to meet the needs of subsequent processing or use. As an important accessory of watches, plastic watch straps also need to go through the slitting process to ensure that the width and length of the watch straps meet the design requirements.

[0003] However, before plastic raw materials enter the slitting equipment, they require corresponding devices for conveying, guiding, and limiting. Existing such devices are relatively simple in function, and most cannot easily adjust for thicknesses and widths of different sizes, resulting in low flexibility and reduced practicality. Therefore, there is an urgent need for a simple, easy-to-operate, and highly adaptable feeding and guiding device for plastic slitting equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience in adjusting the thickness and width of different sizes and the low flexibility, and to propose a feeding guide device for plastic slitting equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding guide device for a plastic slitting machine includes a base;

[0007] Both the No. 1 and No. 2 feeding components are used to transport uncut plastic raw materials. Both the No. 1 and No. 2 feeding components are located inside the base. Both the No. 1 and No. 2 feeding components include an upper feeding roller. The No. 1 and No. 2 feeding components also include a No. 1 lower feeding roller and a No. 2 lower feeding roller, which are rotatably arranged on both sides of the lower part of the base. Sliding holes are opened at both ends of both sides of the upper part of the base. Sliding seats are slidably arranged inside the sliding holes. The two ends of the upper feeding roller are rotatably arranged on one side of two adjacent sliding seats.

[0008] A drive mechanism is used to drive the first lower conveyor roller, the second lower conveyor roller, and the upper conveyor roller to rotate. The drive mechanism is located on one side of the base.

[0009] In one possible design, both the first and second feeding components further include two upper cylinders that are slidably sleeved on both sides of the outer wall of the feed roller. The inside of both sides of the feed roller is provided with tension springs, and the two ends of the tension springs are respectively fixedly disposed on one side of the inner wall of the feed roller and one side of the upper cylinder.

[0010] In one possible design, the first conveying component further includes two first lower cylinders that are slidably sleeved on both sides of the outer wall of the first lower conveyor roller. A first limiting ring is fixedly provided on one side of the first lower cylinder, and the first limiting ring is sleeved on the outer wall of the first lower conveyor roller. The first limiting ring cooperates with the adjacent upper cylinder. A bidirectional threaded shaft is rotatably provided inside the first lower conveyor roller, and the two first lower cylinders are respectively threaded on both sides of the outer wall of the bidirectional threaded shaft.

[0011] In one possible design, the second conveying component further includes two second lower cylinders that are slidably sleeved on both sides of the outer wall of the second lower conveyor roller. A second limiting ring is fixedly provided on one side of the second lower cylinder, and the second limiting ring is sleeved on the outer wall of the second lower conveyor roller. The second limiting ring cooperates with the adjacent upper cylinder.

[0012] In one possible design, a rotating ring is rotatably provided on one side of both the first and second limiting rings. The outer walls of the two rotating rings on the same side are fitted with the same connecting frame. The rotating rings are rotatably disposed inside the connecting frame. A slide cylinder is slidably fitted on one end of the outer wall of the bidirectional threaded shaft. An insertion rod is fixedly provided on one side of the slide cylinder. One end of the insertion rod slides through into the interior of the first lower conveyor roller.

[0013] In one possible design, a threaded rod is rotatably provided on one side of the base, and a common connecting block is fixedly provided between two slides on the same side, the connecting block being threaded onto the outer wall of the threaded rod.

[0014] In one possible design, a fixed seat is fixedly installed on one side of the base, and a second motor is fixedly installed on the top of the fixed seat. The output shaft of the second motor is fixedly installed at one end of a first lower conveyor roller. A lower synchronous pulley is fixedly sleeved on one end of the outer wall of both the first and second lower conveyor rollers, and the outer walls of the two lower synchronous pulleys are driven by the same lower synchronous belt. A movable seat is slidably installed on one side of the base, and a first motor is fixedly installed on one side of the movable seat. The output shaft of the first motor is fixedly installed at one end of one of the upper conveyor rollers. An upper synchronous pulley is fixedly sleeved on one end of the outer wall of both upper conveyor rollers, and the outer walls of the two upper synchronous pulleys are driven by the same upper synchronous belt.

[0015] In this application, during actual use, motor number two drives the first lower conveyor roller to rotate, and through the lower synchronous pulley and lower synchronous belt, drives the second lower conveyor roller to rotate as well. Motor number one drives one of the upper conveyor rollers to rotate, and through the upper synchronous pulley and upper synchronous belt, drives the other upper conveyor roller to rotate. The plastic raw material to be cut is clamped and conveyed between the upper conveyor roller and the adjacent lower conveyor roller to achieve the feeding effect. The first and second limiting rings on both sides of the outer walls of the first and second lower conveyor rollers limit the plastic material, so as to achieve the guiding and limiting effect. For thickness adjustment and adaptation of different sizes, the threaded rod is directly rotated. The threaded rod drives the connecting block to move up and down. The connecting block drives the slide to move. The slide drives the upper conveyor roller to move in the same direction, thereby adjusting the distance between the upper and lower conveyor rollers. For width adjustment of different sizes, the slide cylinder is moved first to make it... One of the insert rods disengages from the interior of the No. 1 lower conveyor roller, releasing the fixed connection between the bidirectional threaded shaft and the No. 1 lower conveyor roller. At this time, the No. 1 lower conveyor roller is prevented from rotating by the self-locking of the No. 2 motor. Subsequently, the bidirectional threaded shaft is driven to rotate by the rotating slide cylinder. The bidirectional threaded shaft will then drive the two No. 1 lower cylinders to move towards each other. The No. 1 lower cylinder drives the No. 1 limit ring to move, thereby adjusting the distance between the two No. 1 limit rings. When the No. 1 limit ring moves outward, the upper cylinder will also be moved by the force of the tension spring. At this time, its corresponding length can be adjusted to match the width of the plastic. When the No. 1 lower cylinder moves, it will drive the rotating ring and the connecting frame to move together, thereby driving the No. 2 limit ring and the No. 2 lower cylinder behind to move, performing the same adaptation adjustment. The upper roller located above the No. 2 lower conveyor roller will also drive the upper cylinder to move through the tension spring for adaptation, thereby realizing the width adjustment.

[0016] In this utility model, the feeding guide device of the plastic slitting equipment can achieve the function of conveying and feeding the plastic to be cut through two sets of feeding components. While having guiding and limiting functions, it can also adjust the thickness and width of the plastic to ensure actual flexibility and can be adjusted and used according to needs.

[0017] In this utility model, the feeding guide device of the plastic slitting equipment can drive the conveying roller in the conveying component through the driving mechanism to achieve the conveying effect, and can also move at the same time when adjusting the thickness;

[0018] In this invention, the device is not only easy to operate, but also can stably guide and convey plastic raw materials through the cooperation of the first and second feeding components. Furthermore, the distance between the conveyor rollers and the position of the corresponding limiting rings can be easily adjusted, making the device adaptable to plastic raw materials of different widths and thicknesses, thus improving the adaptability of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1A feeding guide device includes: a base 1, inside which are a first feeding component and a second feeding component, both used for conveying uncut plastic raw materials. Both the first and second feeding components include an upper feeding roller 4, the first feeding component also includes a first lower feeding roller 5, and the second feeding component also includes a second lower feeding roller 6. The first and second lower feeding rollers 5 and 6 are rotatably mounted on both sides of the lower interior of the base 1. Sliding holes 2 are provided at both ends of the upper sides of the interior of the base 1, and sliding seats 3 are slidably mounted inside the sliding holes 2. The two ends of the upper feeding roller 4 are rotatably mounted on one side of two adjacent sliding seats 3. Subsequently, by driving the feeding rollers to rotate, a clamping and conveying effect is achieved.

[0029] Specifically, a drive mechanism is provided on one side of the base 1. A fixed seat and a sliding seat are fixedly mounted on one side of the base 1, and a second motor 10 and a first motor 8 are fixedly mounted on the other side.

A lower synchronous pulley is fixedly sleeved on one end of the outer wall of both the first and second lower conveyor rollers 6, and the same lower synchronous belt 9 is driven to the outer wall of both lower synchronous pulleys. By driving the first lower conveyor roller 5 to rotate, the second lower conveyor roller 6 can be driven to rotate. The output shaft of the first motor 8 is fixedly mounted to one end of one of the upper conveyor rollers 4. An upper synchronous pulley is fixedly sleeved on one end of the outer wall of both upper conveyor rollers 4, and the same upper synchronous belt 7 is driven to the outer wall of both upper synchronous pulleys. By driving one of the upper conveyor rollers 4, both rollers can rotate simultaneously.

[0030] This application can be used in the field of plastic processing, or in other fields applicable to this application.

[0031] Example 2

[0032] refer to Figure 5 An improvement on Embodiment 1: A feeding guide device for a plastic slitting equipment, applied in the field of plastic processing, wherein a threaded rod 20 is rotatably mounted on one side of the base 1, and a connecting block 21 is fixedly mounted between two slides 3 located on the same side, the connecting block 21 being threaded onto the outer wall of the threaded rod 20. By rotating the threaded rod 20, the two slides 3 can move simultaneously.

[0033] Specifically, for thickness adjustment and adaptation of different sizes, the threaded rod 20 is directly rotated, which drives the connecting block 21 to move up and down. The connecting block 21 drives the slide block 3 to move, and the slide block 3 drives the uploading roller 4 to make the same displacement, thereby adjusting the distance between the uploading roller 4 and the downloading roller.

[0034] Reference Figure 2-4Both the first and second feeding components also include two upper cylinders 11 that are slidably sleeved on both sides of the outer wall of the feed roller 4. The inside of both sides of the feed roller 4 is provided with tension springs 14, and the two ends of the tension springs 14 are respectively fixedly installed on one side of the inner wall of the feed roller 4 and one side of the upper cylinder 11.

[0035] The first conveying component also includes two lower cylinders 12, which are slidably sleeved on both sides of the outer wall of the lower roller 5. A limiting ring 13 is fixedly installed on one side of the lower cylinder 12, and the limiting ring 13 is sleeved on the outer wall of the lower roller 5. The limiting ring 13 cooperates with the adjacent upper cylinder 11. The limiting rings 13 and 17 on both sides of the outer wall of the lower roller 5 and the second lower roller 6 limit the plastic, so as to achieve the effect of guiding and limiting. The lower roller 5 has a bidirectional threaded shaft 15 rotatably installed inside, and the two lower cylinders 12 are respectively threaded on both sides of the outer wall of the bidirectional threaded shaft 15.

[0036] The second conveying component also includes two second lower cylinders 16 that are slidably sleeved on both sides of the outer wall of the second lower conveyor roller 6. A second limiting ring 17 is fixedly provided on one side of the second lower cylinder 16, and the second limiting ring 17 is sleeved on the outer wall of the second lower conveyor roller 6. The second limiting ring 17 cooperates with the adjacent upper cylinder 11.

[0037] Reference Figure 6 One side of the first limiting ring 13 and the second limiting ring 17 is provided with a rotating ring 22. The outer wall of the two rotating rings 22 located on the same side is fitted with the same connecting frame 24, and the rotating ring 22 is rotatably disposed inside the connecting frame 24.

[0038] Specifically, for width adjustment of different sizes, the slide cylinder 23 is first moved so that the insert rod 18 on one side disengages from the interior of the first lower conveyor roller 5, thus releasing the fixed connection between the bidirectional threaded shaft 15 and the first lower conveyor roller 5. At this time, the first lower conveyor roller 5 is prevented from rotating by the self-locking of the second motor 10. Then, by rotating the slide cylinder 23, the bidirectional threaded shaft 15 is driven to rotate. The bidirectional threaded shaft 15 will then drive the two first lower cylinders 12 to move towards each other. The first lower cylinders 12 drive the first limiting ring 13 to move, thereby adjusting the distance between the two first limiting rings 13. When the first limiting ring 13 moves outward, the upper cylinder 11 will also move under the force of the tension spring 14. At this time, its corresponding length can be adjusted to match the width of the plastic. When the first lower cylinder 12 moves, it will drive the rotating ring 22 and the connecting frame 24 to move together, thereby driving the second limiting ring 17 and the second lower cylinder 16 behind to move for the same adaptation adjustment. The upper roller 4 located above the second lower roller 6 will also drive the upper cylinder 11 to move through the tension spring 14 for adaptation, thereby realizing the width adjustment.

[0039] Reference Figure 5The base 1 has a housing 19 on one side, and the motor, synchronous belt and other components are located inside it for protection.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of motor 8 and motor 10 are commonplace and are conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
