Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and particularly relates to a bobbin clamping and releasing assembly. Background Art

[0002] A winding machine is used for winding silk threads in textile production and processing; after the silk thread raw materials enter the factory, they are usually wound into bundles on a relatively wide reel, and the diameter of the silk cake is relatively large; the volume and weight are both large; it is laborious during the handling and transfer process, and it cannot be directly placed on the textile equipment for direct use; therefore, it is often necessary to divide the large silk cake into several small discs to facilitate the transfer and use of the silk thread materials. The disc division of the silk thread is usually completed by a winding machine. A wire feeding roller and a winding roller are arranged on the winding machine. A large bundle of silk threads is placed on the wire feeding roller, and several empty small bobbins are placed on the winding roller. The silk threads are output through the wire feeding roller and wound on the small bobbins on the winding roller respectively to complete the disc division of the silk threads.

[0003] Neither the wire feeding roller nor the winding roller is provided with a clamping and fixing device for the bobbin. The bobbin is sleeved on the winding roller, and the bobbin is fixed on the winding roller entirely by the frictional force between the bobbin itself and the outer wall of the winding roller or the interference fit between the two; during the operation of the equipment, the winding roller drives the bobbin to rotate. Since the bobbin does not have any auxiliary clamping and fixing structure, with the rapid rotation of the winding roller, the bobbin is likely to shift on the winding roller; ultimately, the bobbin may fall off the winding roller. Summary of the Utility Model

[0004] The utility model provides a bobbin clamping and releasing assembly, which is arranged on both sides of a bobbin and is detachably clamped and fixed on the surface of the winding roller; the clamping assemblies on both sides can play a role in limiting and clamping the middle bobbin, preventing the bobbin from shifting during the winding process and avoiding the situation of falling off the winding roller; while the assembly plays a clamping role on the bobbin, it does not have a complicated installation and fixing structure and can be quickly disassembled from the winding roller. The utility model solves the problem that there is no structure or component on the winding roller and the wire feeding roller of the current winding machine that can actually clamp the silk bobbin, and the fixation between the two is completely achieved by the friction or interference fit between the bobbin and the roller body, and the bobbin is prone to shift or even fall off the roller body during the rotation following the roller body.

Detailed implementation manners

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some, rather than all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0048] Embodiment 1

[0049] A bobbin clamping and releasing assembly includes: a collar disc 1, a clamping block 2, and a clamping pressure applying assembly;

[0050] As Figure 1 shown, a circular through hole is provided in the middle of the collar disc 1, and the diameter of the circular through hole is slightly larger than the outer diameters of the wire feeding roller and the winding roller; through the circular through hole on the collar disc 1, the collar disc 1 can be sleeved on the wire feeding roller or the winding roller; there is no connecting structure between the collar disc 1 and the wire feeding roller and the winding roller, and the two are detachably connected.

[0051] On the left and right sides of the collar disc 1, two clamping blocks 2 are symmetrically arranged on the upper and lower sides of each side. The purpose of setting the clamping blocks 2 is to use the clamping blocks 2 to apply pressure to the outer wall of the wire feeding roller or the winding roller, so as to clamp the surface of the roller body, thereby achieving the effect of fixing the collar disc 1. Similarly, after the clamping blocks 2 release the surface of the roller body, the collar disc 1 can be detached from the wire feeding roller or the winding roller.

[0052] In order for the clamping block 2 to clamp or release the wire feeding roller or the winding roller, a clamping pressure applying assembly needs to be set for the clamping block; the clamping pressure applying assembly is used to control the clamping block 2 to achieve the above functions.

[0053] As Figure 1 shown, the clamping pressure applying assembly in this embodiment includes: a pressure applying elastic member 3 and a hook 301;

[0054] Pressure applying elastic members 3 are arranged between the upper and lower two clamping blocks 2 on the left and right sides of the collar disc 1; the pressure applying elastic members 3 are arranged on both sides of the upper and lower two clamping blocks 2;

[0055] The upper end of the pressure applying elastic member 3 is fixedly connected to the side wall of the upper clamping block 2, and the lower end of the pressure applying elastic member 3 is detachably connected to the hook 301 arranged on the side wall of the lower clamping block 2;

[0056] The pressure applying elastic member 3 in this embodiment is a spring; both ends of the pressure applying elastic member 3 are arranged on the upper and lower clamping blocks 2 respectively, and the pressure applying elastic member 3 applies an opposite acting force to the upper and lower clamping blocks 2, so that they clamp the wire feeding roller or the winding roller.

[0057] If the clamping block 2 is fixedly connected to the collar disc 1 without any room for movement; then setting the pressure applying elastic member 3 between the clamping blocks 2 is meaningless, because no matter how the clamping block 2 is acted on, the clamping block 2 will not have any displacement change and cannot clamp the roller body either.

[0058] Therefore, when the pressure applying elastic member 3 of this embodiment is used as the clamping pressure applying assembly, the clamping block 2 should be arranged on the collar disc 1 so that it can move up and down;

[0059] As Figure 2 shown, on both sides of the collar disc 1, mounting grooves 101 are provided at positions corresponding to the upper and lower sides where the clamping blocks 2 are installed; an embedding block is provided on the contact surface between the clamping block 2 and the collar disc 1; when the clamping block 2 is arranged on the collar disc 1, the embedding block is movably arranged in the mounting groove 101; so that the clamping block 2 can move up and down on the collar disc 1.

[0060] When the upper clamping block 2 moves downward to the maximum position and the lower clamping block 2 moves upward to the maximum position, the lower arc edge of the upper clamping block 2 and the upper arc edge of the lower clamping block 2 both exceed the edge of the circular through-hole in the middle of the collar disc 1.

[0061] The collar disc 1 is sleeved on the roller body. At this time, the upper clamping block 2 can naturally fit on the roller body, while the lower clamping block 2 should be in a state of not fitting with the roller body; then the lower end of the pressure-applying elastic member 3 is connected to the hooks 301 on both sides of the lower clamping block 2; under the action of the pressure-applying elastic member 3, the upper and lower clamping blocks 2 move towards each other, and because there is a margin of movement for the upper and lower clamping blocks 2, the upper and lower clamping blocks 2 can clamp on the surface of the roller body. At both ends close to the wire-feeding roller, a component in this embodiment is provided respectively, and the distance between the two components is adjusted. A wire spool is placed between the two components, and the spool is clamped from both sides of the spool. According to the number of spools to be placed on the winding roller, a corresponding number of clamping components are provided on the winding roller, and one spool can be placed within the distance between two adjacent components; similarly, according to the width of the spool, the distance between the two clamping components is adjusted to clamp the spool.

[0062] Embodiment 2

[0063] Based on Embodiment 1, in Embodiment 1, the clamping and pressure-applying component uses a pressure-applying elastic member. By arranging the pressure-applying elastic member 3 between the upper and lower clamping blocks 2, it applies pressure to the clamping blocks 2 towards each other to clamp the roller body. During operation, the lower end of the pressure-applying elastic member 3 needs to be stretched to the hook 301 provided on the side wall of the lower clamping block 2; during operation, while the lower clamping block 2 is fitted to the roller body, the lower end of the pressure-applying elastic member 3 is hung on the lower clamping block 2. This is rather cumbersome in operation.

[0064] In this embodiment, the clamping and pressure-applying component is set as a lever clamping structure, as Figure 3 shown, the lever clamping structure includes: a movable pressure block 5, a linkage rod 6, a pressure rod 7, and an elastic pressure strip 8; when the lever clamping structure is adopted, the clamping block 2 is fixedly connected to the collar disc 1.

[0065] On the left and right sides of the collar disc 1, and in the center of the clamping block 2 located below, a pressure block groove 201 is provided; both the upper and lower ends of the pressure block groove 201 are of an open structure; an active pressure block 5 is movably arranged in the pressure block groove 201;

[0066] The upper end of a linkage rod 6 is centrally arranged below the active pressure block 5; the lower end of the linkage rod 6 is hinge-connected to the tail end of a pressure rod 7 through a hinge seat; an elastic pressure strip 8 is arranged between the middle of the pressure rod 7 and the clamping block;

[0067] When the elastic pressure strip 8 is not squeezed, a part of the active pressure block 5 extends out from the upper end of the pressure block groove 201.

[0068] Hold the head end of the pressure rod 7 and press the pressure rod 7 to squeeze the elastic pressure strip 8. At this time, the tail end of the pressure rod 7 drives the linkage rod 6 to move, and the linkage rod 6 drives the active pressure block 5 to move into the pressure block groove 201; until the active pressure block 5 is completely located in the pressure block groove 201; then the collar disc 1 and the clamping block 2 can be sleeved on the wire feeding roller and the winding roller together; release the pressure rod 7. At this time, the elastic pressure strip 8 needs to recover, the head end of the pressure rod 7 drives the linkage rod 6 again, and the linkage rod 6 drives the active pressure block 5 to move in the direction of extending out of the pressure block groove 201. Finally, under the action of the elastic pressure strip 8, the active pressure block 5 can tightly abut against the surface of the wire feeding roller or the winding roller to achieve clamping.

[0069] As a preferred implementation method, only the pressure rod clamping structure is provided on the clamping block 2 below; when operating on one side, it is not very convenient to apply force; in addition, the clamping effect on one side may not be ideal;

[0070] As Figure 4 shown, the pressure rod clamping structure is arranged on the clamping blocks 2 on the upper and lower sides of the left and right sides of the collar disc 1. At this time, when operating, one hand can press the pressure rods 7 on the upper and lower sides at the same time to apply force simultaneously; it is more convenient to operate; in addition, active pressure blocks 5 are arranged on both the upper and lower sides, and clamping is carried out from both the upper and lower sides of the roller body; the clamping effect is more ideal.

[0071] Embodiment 3

[0072] Based on Embodiment 1 or Embodiment 2, in the above two embodiments, a component for clamping both sides of the wire spool is provided; it can prevent the spool from not rotating synchronously with the roller body to complete the winding of the wire. However, during the winding process, as the winding amount of the wire increases, the diameter of the wire cake also becomes larger and larger. However, the outer diameter of the entire clamping component is fixed. When the diameter of the wire cake increases to a certain extent, the clamping device cannot clamp the excess part of the wire cake from both sides to ensure the flat winding of the wire cake.

[0073] As Figure 1 or Figure 3As shown, in this embodiment, baffles 4 are provided on the clamping blocks 2 on the upper and lower sides of the left and right sides of the collar plate 1; the baffles 4 extend, which can clamp and limit the silk cake from both sides of the silk cake, so that both sides of the silk cake can remain flat during the winding process, and the situation where the silk cake collapses from one side will not occur.

[0074] In order to ensure that the baffle 4 will not cause abrasion to the silk thread, a soft cushion layer 401 is provided on the contact surface between the baffle 4 and the silk cake. Here, the soft cushion layer 401 can be set as a smooth and flat soft silicone cushion layer; when the soft cushion layer 401 contacts the silk cake from both sides, it can protect the silk cake and avoid abrasion to the silk thread.

[0075] Embodiment 4

[0076] Based on Embodiment 3, as the diameter of the silk cake increases, the fixed-length baffle 4 may not be sufficient, and part of the silk cake will exceed the baffle 4; this part of the exceeding silk cake cannot be protected by the clamping and limiting of the baffle 4.

[0077] As Figure 5 and Figure 6 shown, in this embodiment, the baffle 4 is detachably installed on the clamping block 2; the specific structure is:

[0078] Baffle insertion posts 202 are provided at the installation position of the baffle 4 on the clamping block 2; a slot 402 is opened at the lower end of the baffle 4;

[0079] Inserting the slot 402 on the baffle insertion post 202 can detachably install the baffle 4 on the clamping block 2.

[0080] Baffle 4 models with different lengths can be set. Before operation, according to the diameter of the silk cake to be wound, replace the baffle 4 with a suitable length on the clamping block 2.
