Description

Technical Field

[0001] The utility model relates to the technical field of knitting equipment, and more specifically, to a split type independently controlled lower roller. Background Art

[0002] When a flat knitting machine is knitting, it is necessary to pull the forming piece of clothing to provide downward tension, and this pulling is completed by a roller mechanism. The roller mechanism in the prior art consists of a pair of symmetrically arranged left and right rollers. Each roller includes a relatively thick lower roller and a relatively thin upper roller. There is a tensioned roller leather around the two roller shafts, which wraps the upper and lower roller shafts. When the lower roller rotates, it drives the roller leather to rotate. Since the roller leather has a rough surface, when a pair of rollers rotate downward and inward at the same time, the two rollers close, that is, approach each other and generate a pulling force on the piece of clothing clamped between the two roller leathers; when a pair of rollers rotate downward and outward at the same time, the two rollers open, that is, move relatively away from each other and do not generate pressure on the piece of clothing.

[0003] In actual production, it is necessary to intermittently subject or not subject the piece of clothing being knitted to pulling according to different patterns of the piece of clothing. The most common mode is that the piece of clothing continuously and synchronously switches between being pulled and not being pulled. For this purpose, the roller mechanism needs to be able to open or close quickly. The roller mechanism in the aforementioned prior art has inflexible opening and closing actions, cannot accurately control the opening and closing amplitude, and cannot independently control the rotation speed of the lower roller rod.

[0004] Having noticed the deficiencies of the above-mentioned conventional lower roller devices, the applicant of the present invention has proposed a practical solution, and thus filed an application for this case. Summary of the Utility Model

[0005] In order to overcome at least one of the above-mentioned defects in the prior art, the utility model proposes a split type independently controlled lower roller, which respectively uses two different motors to realize the self-rotation and opening and closing actions of the lower roller rod.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions: A split type independently controlled lower roller includes: side plates, a double lower roller rod, a driving motor, and an opening and closing motor. The two sides of the double lower roller rod are arranged inside the side plates through gear plates, and the two gear plates are meshed with each other through teeth. The opening and closing motor is hinged to an opening and closing pull rod through a cam, and the opening and closing pull rod is hinged to the gear plate and drives the gear plate to swing. The double lower roller rod is divided into a front lower roller rod and a rear lower roller rod. A driving motor is provided on one side of each of the front lower roller rod and the rear lower roller rod, and the two driving motors respectively drive the front lower roller rod and the rear lower roller rod to rotate self by a gear set.

[0007] Specifically, the side plate is provided with two mounting shafts, which are inserted into the bearing seat of the gear plate. The drive motor is installed on the inner side of the side plate through the motor seat. The gear located on the drive motor shaft is meshed with the gear set on the gear plate.

[0008] Specifically, two Hall sensors are provided on the side panel, and an induction magnet is installed on the gear plate on one side of the Hall sensor. The induction magnet is located between the two Hall sensors to control the swing amplitude and angle of the double lower roller rods and adjust the distance between the double lower roller rods.

[0009] Specifically, the Hall sensor is installed on the inner side of the side panel through an adjustment seat. An arc-shaped slot is provided on the adjustment seat. The bolt passes through the arc-shaped slot and is installed in the bolt hole of the side panel. The adjustment seat can change its position as needed to adjust the distance between the two Hall sensors.

[0010] Specifically, a fixing rod is provided at the bottom of the gear plate and the inner side of the side plate, and a tensioning spring is sleeved between the two fixing rods. The tensioning spring can exert a certain pulling force on the gear plate to eliminate the gap between the teeth. The gap between the double lower roller rods remains consistent during operation, thereby improving its own stability.

[0011] Specifically, the outer surface of the double lower roller rod is covered with a roller leather cover, and the left and right ends of the double lower roller rod are installed on the gear plate through bearings. When the cloth contacts the raised patterns, it will be tightened, otherwise, the cloth will be relaxed, so that the cloth is subjected to stable tension.

[0012] Specifically, the opening and closing motor adopts a stepping motor, and the driving motor adopts a DC motor. The opening and closing motor, the driving motor and the Hall sensor are all electrically connected to the controller. The controller limits the opening and closing amplitude of the double lower roller rod through the signal of the Hall sensor, and controls the rotation speed of the double lower roller rod through the motor.

[0013] Compared with the prior art, the beneficial effects are:

[0014] The opening and closing motor of the present application drives the double lower roller rods to open and close through the gear plates on the left and right sides, and cooperates with the Hall sensor to drive and control the opening and closing amplitude of the double lower roller rods, thereby improving the accuracy of the opening and closing angles of the double lower roller rods and controlling the amplitude between the double lower roller rods. This can be applied to fabrics of different thicknesses, so that the friction force of the double lower roller rods on the fabric is moderate, avoiding wear on the fabric while ensuring appropriate fabric tension.

[0015] This application uses a driving motor to drive the rotation of the double lower roller rods. The front lower roller rod and the rear lower roller rod are each driven by a driving motor on one side to rotate themselves. When weaving different fabrics, they can change their own rotation speed to create a speed difference between the front and rear lower roller rods. During single-sided weaving, different forces are applied to the two sides to avoid excessive tension on the unwoven surface. Description of the Drawings

[0021] The drawings are only for illustrative purposes and should not be construed as limiting the present patent; for better illustration of this embodiment, some components in the drawings may be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The positional relationships described in the drawings are only for illustrative purposes and should not be construed as limiting the present patent.

[0022] As Figures 1 to 5 shown, an opening and closing type independently controlled lower roller includes: side plates 1, double lower roller rods 2, drive motors 3, opening and closing motors 4. Both sides of the double lower roller rods 2 are arranged inside the side plates 1 through gear plates 5. The two gear plates 5 are meshed with each other through teeth. The opening and closing motor 4 is hinged to the opening and closing pull rod 61 through a cam 6. The opening and closing pull rod 61 is hinged to the gear plate 5 and drives the gear plate 5 to swing. The double lower roller rods 2 are divided into a front lower roller rod and a rear lower roller rod. A drive motor 3 is provided on one side of each of the front lower roller rod and the rear lower roller rod. The two drive motors 3 drive the front lower roller rod and the rear lower roller rod to rotate independently through gear sets 31. The outer surface of the double lower roller rods 2 is sleeved with roller leather sleeves. The left and right ends of the double lower roller rods 2 are both installed on the gear plates 5 through bearings. The opening and closing motor 4 adopts a stepping motor, and the drive motor 3 adopts a DC motor. The opening and closing motor 4, the drive motor 3, and the Hall sensor 8 are all electrically connected to the controller.

[0023] The opening and closing motor 4 is hinged to the opening and closing pull rod 61 through the cam 6. The driving shaft of the opening and closing motor 4 drives the cam 6 to rotate, causing the opening and closing pull rod 61 to move back and forth, thereby driving the gear plate 5 to swing by a certain angle. The opening and closing motor 4 can also replace the cam 6 with a gear. Teeth are provided on the opening and closing pull rod 61, and the teeth are meshed with the gear. Rotating the gear drives the opening and closing pull rod 61 to move back and forth, thereby driving the gear plate 5 to swing.

[0024] In the above solution, two mounting shafts 7 are provided on the side plate 1. The mounting shafts 7 are inserted into the bearing seats of the gear plate 5. The driving motor 3 is mounted on the inner side of the side plate 1 through a motor base. The gear on the rotating shaft of the driving motor 3 meshes with the gear set on the gear plate 5.

[0025] In the above solution, two Hall sensors 8 are provided on the side plate 1. An induction magnet is mounted on the gear plate 5 on one side of the Hall sensors 8. The induction magnet is located between the two Hall sensors 8. The Hall sensors 8 are mounted on the inner side of the side plate 1 through an adjustment seat 81. An arc-shaped slot 82 is provided on the adjustment seat 81. A bolt passes through the arc-shaped slot 82 and is installed in the bolt hole of the side plate 1. At a suitable position, the position of the adjustment seat 81 is set, and then fixed with bolts, so as to determine the positions of the two Hall sensors 8 and ensure the angular range of the swing of the gear plate 5.

[0026] In the above solution, a fixing rod 91 is provided at the bottom of the gear plate 5 and on the inner side of the side plate 1. A tension spring 9 is sleeved between the two fixing rods 91. Tension springs 9 are installed on both side plates 1. The tension springs 9 all pull the gear plate 5 tightly to eliminate the gap between the teeth of the gear plate 5.

[0027] Principle of the swing of the double lower roller rods 2: The controller sends a signal to start the opening and closing motor 4. The opening and closing motor 4 drives the opening and closing pull rod to swing through the cam 6. The opening and closing pull rod is used to pull the gear plate 5. The two gear plates 5 on both sides rotate around the mounting shaft 7 as the center. The two gear plates 5 on one side mesh with each other through the teeth. During the rotation process, the two gear plates 5 swing outwards or close inwards at the same time to adjust the distance between the double lower roller rods 2 to adapt to fabrics of different thicknesses.

[0028] Principle of the self-rotation of the double lower roller rods 2: The controller sends a signal to start the driving motor 3. A gear is provided at the front end of the rotating shaft of the driving motor 3. The gear is used to drive the gear set on the gear plate 5 to rotate. The gear set drives the lower roller rods to rotate self. Driving motors 3 are provided on both side plates 1. The front lower roller rod and the rear lower roller rod are separately controlled by the two driving motors 3 to rotate at different speeds. It can be used for single-sided knitting and can also be applicable to fabrics of different materials. It can apply appropriate tension on both sides of the fabric, effectively avoiding unnecessary abrasion of the fabric during the smooth transportation of the fabric.

[0029] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation modes of the present utility model. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description, such as the application of two-system and three-system leading machine mountain plates, etc. It is not necessary and impossible to enumerate all the implementation modes here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
