Description

TECHNICAL FIELD

[0001] The utility model relates to textile machinery especially the technical field of gill box, and particularly relates to a gill box clamping device locking mechanism. BACKGROUND

[0002] The gill box is a machine used for combing and beating-up in flax spinning, which has the functions of splitting fiber bundle, combing out short fibers and impurities, and straightening and parallelizing fibers. The clamping device is the main working component of the gill box, which is used to clamp the beaten-up bundle so that it can be combed by the needles of the needle curtain. During operation, the clamping device moves along the track connecting the left and right combing machines and the front and rear automatic machines. When the lifting frame is at the lower position, the fibers are combed by the needles of the upper needle curtain; when the lifting frame is lifted to the highest position, the bundle is separated from the needle curtain, and then the clamping device moves forward by one section, and then the lifting frame is lowered again so that the bundle is combed by the needles of the next section. Under the combing of the needles of multiple needle curtains, the bundle becomes straight and parallel, and short fibers and impurities are combed out.

[0003] In the design of the clamping device, a connecting plate is usually designed, the main component of the clamping device is arranged below the connecting plate, and a displacement cylinder for driving the clamping device to move is arranged above the connecting plate. The main component of the clamping device mainly includes an upper plate, a lower plate, and a clamping mechanism for controlling the upper plate and the lower plate to effectively clamp the beaten-up bundle.

When clamping is needed, the hook is connected with the limiting column, and the hook is kept connected with the limiting column by the force applied by the spring. When the upper clamping plate and the lower clamping plate need to be loosened, the spring is compressed by applying force to it, the hook is rotated and separated from the limiting column.

However, in actual use, if the upper end of the spring receives pressure, the clamping device may be unlocked, which may cause the clamping device to fall off and may cause the clamping operation to be unstable, and the reliability is poor.

DETAILED DESCRIPTION

[0025] The utility model will be explained further in detail now in combination with the drawings. These drawings are all simplified schematic diagrams, only in the schematic mode explain the basic structure of the utility model, therefore it only shows the structure related to the utility model, the direction and reference (such as, up, down, left, right, etc.) can be used only to help the description of the features in the drawing. Therefore, the following specific embodiments are not in the restrictive sense, and the scope of the claimed subject matter is only limited by the appended claims and their equivalents.

[0026] As Figures 1 to 6 The utility model discloses a kind of gill box binder locking mechanisms, it is the optimal embodiment of the utility model.

[0027] The gill box binder locking mechanism includes upper and lower oppositely arranged upper plate 8 and lower plate 12, and the lower plate 12 is fixedly clamped with the cover opening mechanism arranged on the upper plate 8. The rubber pad 10 is fixed on the lower end surface of the upper plate 8. The friction between the mechanism and the beaten bundle is improved through the rubber pad 10, so as to improve the clamping effect on the beaten bundle.

[0028] In the embodiment, the cover opening mechanism includes a main cover opening mechanism and an auxiliary cover opening mechanism. The main cover opening mechanism is placed on the lower plate 12 after the beaten bundle, and the upper plate 8 and the lower plate 12 are positioned and locked in the width direction of the upper plate 8 and the lower plate 12. The auxiliary cover opening mechanism cooperates with the lower plate 12 in the length direction of the upper plate 8 and the lower plate 12 after the main cover opening mechanism is locked, effectively supports the lower plate 12, so that the lower plate 12 does not fall off in the action process of the binder, and the reliability of the binder is ensured.

[0029] Specifically, such as Figure 1 The lid-opening mechanism shown also includes a main lid-opening support 4 and an auxiliary lid-opening support 5. The main lid-opening support 4 is a U-shaped bent plate with an opening facing downwards. There are two main lid-opening mechanisms, symmetrically arranged on the outer end faces of both sides of the U-shaped bent plate. The auxiliary lid-opening support 5 is a flat plate, laid flat inside the opening of the U-shaped bent plate. There are two auxiliary lid-opening mechanisms, symmetrically arranged on the flat plate. The main and auxiliary lid-opening mechanisms can be locked, positioned, and supported on both sides of the upper and lower plates 12 in the width direction and length direction, respectively.

[0030] The main support 4 and auxiliary support 5 of the cap opener are connected to the power mechanism of the combing machine via connectors and are driven by the power mechanism of the combing machine. In actual production assembly, the main support 4 and auxiliary support 5 of the cap opener can be fixed as an integral structure and driven by the same power mechanism, or they can be designed separately and driven by different cylinders / linear rails, etc. When the main support 4 and auxiliary support 5 of the cap opener are separate structures, the power mechanism and movement trajectory of the two need to be designed to ensure their synchronization and to ensure that the auxiliary support 5 can stably maintain the cooperation between the two cap opening arms 9 and the lower plate 12, so as not to detach during the movement and thus affect the support effect.

[0031] Based on the above structural components, such as Figure 4 and Figure 6 As shown, the main lid-opening mechanism includes a main lid-opening cylinder 1, an opening hook 2, and a spring 3. The main lid-opening cylinder 1 is fixed on the main support 4 of the lid opener. The output end of the main lid-opening cylinder 1 is connected to a top block 13, and the lower end face of the top block 13 abuts against the opening hook 2. The upper plate 8 has a limiting post 18. In the component selection design, the opening hook 2 adopts an integral molding structure, including a pressure-bearing upper part 2-1, a rotating middle part 2-2, and a lower hook part 2-3, which are integral structures from top to bottom. The rotating middle part 2-2 is rotatably mounted on the upper plate 8 through a support shaft. The output end of the main lid-opening cylinder 1 is connected to the pressure-bearing upper part 2-1. The upper end of the spring 3 is elastically connected to the pressure-bearing upper part 2-1, and the lower end is elastically connected to the upper end face of the upper plate 8. The lower hook part 2-3 is hooked and engaged with the limiting post 18. The limiting post 18 is located below the support shaft, which serves as the rotation center of the opening hook 2. The limiting post 18 acts as a positioning and locking component for the opening hook 2 to engage and lock with the lower plate 12. During use, the opening hook 2 is opened by the action of the main opening cylinder 1. When it is necessary to lock with the lower plate 12, the main opening cylinder 1 does not apply pressure through the top block 13. Under the action of the spring 3, the upper part 2-1 of the opening hook 2 is pushed up, and the opening hook 2 rotates relative to the support shaft. The lower hook part 2-3 engages with the limiting post 18, thereby completing the locking of the upper plate 8 and the lower plate 12 on the width side.

[0032] As Figure 5 shown, the auxiliary cover opening mechanism includes an auxiliary cover opening cylinder 16, a connecting rod device and a cover opening arm 9. The connecting rod device includes a first connecting rod shaft 20, a second connecting rod shaft 15, a swing arm 14 and a connecting plate 7, the first connecting rod shaft 20 is rotationally arranged on the pull block 19, the swing arm 14 is hingedly connected to one end of the first connecting rod shaft 20 and the other end is hingedly connected to the second connecting rod shaft 15, the two ends of the second connecting rod shaft 15 are respectively rotationally connected to the lower end surface of the auxiliary support 5 of the cover opener through the fixing block 6, the side end of the swing arm 14 cooperating with the second connecting rod shaft 15 is further fixed with a swing seat sleeve 21, the connecting plate 7 is fixed on the swing seat sleeve 21, and the cover opening arm 9 is fixed on the connecting plate 7. The lower end of the cover opening arm 9 has a supporting part 11 corresponding to the direction close to the two side main cover opening mechanisms. The supporting part 11 is in frictional cooperation with the lower edge of the lower plate 12 and supports the lower plate 12, and the supporting part 11 is arranged at the two ends of the cover opening arm 9, which on the one hand ensures the reliability of the support from the two side ends, and on the other hand provides a placement space for the beaten hemp, avoiding interference with the placement and position of the beaten hemp.

[0033] In the embodiment, in order to further improve the synchronicity of the auxiliary locking mechanism, the two groups of auxiliary cover opening mechanisms share the same double-rod cylinder as the auxiliary cover opening cylinder 16. The output ends of the two output rods of the double-rod cylinder are fixed with the same pull block 19. The two ends of the pull block 19 are respectively hingedly connected to the first connecting rod shaft 20 of the two groups of auxiliary cover opening mechanisms. Through the arrangement of the double-rod cylinder, the control operation of the two groups of auxiliary cover opening mechanisms can be synchronized.

[0034] Operation process:

[0035] 1. The beaten hemp bundle 17 is laid on the upper end surface of the lower plate 12, the main cover opening mechanism is driven to descend by the main support 4 of the cover opener, and after being in place, the main cover opening cylinder 1 operates, the output end presses down the top block 13, the top block 13 applies pressure to the compressed upper part 2-1 of the open hook 2, the open hook 2 rotates relative to the supporting shaft, at this time the spring 3 is compressed under stress, the lower hook part 2-3 of the open hook 2 opens outward, and then the output end of the main cover opening cylinder 1 is recovered, the spring 3 restores under the action of the elastic force and tops the compressed upper part 2-1 of the open hook 2, the open hook 2 reversely rotates relative to the supporting shaft, the lower hook part 2-3 of the open hook 2 moves inward and cooperates with the limiting column 18 to hook, and the upper plate 8 and the lower plate 12 are locked on the width side.

[0036] 2. Then, the auxiliary lid-opening mechanism activates, the double-rod cylinders activate, and the two rods move downwards synchronously, driving the pull block 19 to move downwards. The first connecting shafts 20 of the two auxiliary lid-opening mechanisms move downwards synchronously. The swing arm 14 is driven by the first connecting shaft 20, with its outer end positioned in the height direction by the second connecting shaft 15, and the first connecting shaft 20 at the inner end descending. The outer end of the swing arm 14 rotates outwards relative to the second connecting shaft 15. At this time, the connecting plate 7 fixed to the swing arm 14 extends outwards synchronously, driving the lid-opening arm 9 to open relatively outwards. Then, the double-rod cylinders activate, and the two rods retract upwards synchronously. Through the transmission of the connecting rod device, the lid-opening arm 9 rotates inwards, thereby causing the supporting part 11 to rub against the lower edge of the lower plate 12, completing the supporting operation of the lower plate 12, and avoiding the risk of the lower plate 12 falling off due to the locking failure of the upper plate 8 and the lower plate 12 after locking.

[0037] The combing machine's hemp clamping locking mechanism is designed in this way. The main opening mechanism is used on the width side of the upper plate 8 and the lower plate 12 for locking operation, while the auxiliary opening mechanism is used on the length side to provide secondary support for the lower plate 12. This provides an upward supporting force for the lower plate 12 after locking, further improving the reliability of the upper plate 8 and the lower plate 12 after locking. The swing clamping operation is convenient and quick.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
