Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and more specifically to an improved stop roller mechanism for pre-releasing the roll roll in a roll roll machine. Background Technology

[0002] In the textile production process, after the knitting machine finishes weaving the fabric, it must be pulled to a fabric roll machine. The fabric roll machine is used to roll the fabric onto a roll roller. After the fabric is rolled, it is cut and then the roll roller is taken out and transported to the storage area. Moreover, with the advancement of technology, the unloading, unloading, and transportation of fabric rolls have gradually become automated. However, in actual use, when a roll roller completes its target work, the machine needs to be stopped and a new roll roller needs to be replaced. The replacement process takes a certain amount of time, which reduces the efficiency of fabric rolling.

[0003] Based on this, Chinese Patent Publication No. CN 113862890 B designed a fabric winding machine with a pre-release function, including a fabric winding base installed on a weaving device and a main control device. The fabric winding base includes a base and supports erected on both sides of the base. Between the two supports are arranged multiple transition rollers, a storage mechanism, a fabric dropping mechanism, a fabric winding mechanism, a fabric cutting mechanism, and a fabric pushing machine. The storage mechanism includes storage tracks respectively arranged on the two supports, multiple fabric winding rollers arranged in the storage tracks, and a first driving device for controlling the fabric winding rollers to slide down one by one. The first driving device is arranged on the supports. The first driving device is a first cylinder. The first cylinder is connected to the main control device, and the end of the piston rod of the first cylinder is connected to a baffle through a first connecting rod, so as to drive the baffle to move back and forth on the storage track through the first cylinder.

[0004] With the aforementioned storage mechanism, the extension and retraction of the first cylinder is controlled to pull the baffle out or insert it from the storage track, allowing new fabric rolls to be controlled one by one to fall into the corresponding process for fabric winding. However, in actual fabric winding, the fabric rolls are quite heavy, and multiple rolls are stacked sequentially from bottom to top on the baffle. This causes the piston rod of the first cylinder and the baffle to bear the weight of all the rolls, which makes the baffle prone to jamming during the pulling process, affecting the descent of new rolls and thus the continuity of winding. This results in frequent machine stops for maintenance, affecting winding efficiency. Moreover, the piston rod of the first cylinder is prone to deformation after prolonged use.

[0005] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0006] The purpose of this invention is to provide an improved stop roller mechanism for pre-releasing the roll roll in a roll rolling machine, which can prevent jamming and deformation when acquiring a new roll roll, and ensures continuous winding and winding efficiency.

[0007] To achieve the above objectives, the solution of this utility model is:

[0008] An improved guide roller mechanism for pre-releasing fabric rolls in a fabric winding machine is disclosed. The fabric winding machine includes a fabric winding base for mounting weaving equipment. The fabric winding base includes two opposing supports. A storage mechanism and a fabric dropping mechanism including two dropping tracks are installed between the two supports. The fabric dropping mechanism is located in front of the storage mechanism. The storage mechanism includes storage tracks respectively arranged on the two supports and multiple fabric rolls arranged between the two storage tracks. The storage track and the fabric dropping track on each support are interconnected and together form an L-shape. The mechanism also includes a guide roller mechanism for controlling the fabric rolls to slide down one by one. The guide roller mechanism includes two swing devices and two telescopic devices. The two swinging devices are respectively mounted on the bracket, and each swinging device includes a swinging actuator. The rear parts of the two swinging actuators extend into the connection position between the corresponding storage track and the fabric drop track, and swing at the connection position to push the fabric roll into the fabric drop track. Each of the two telescopic devices includes a telescopic actuator, and the two telescopic actuators are respectively arranged on the corresponding bracket in such a way that they can extend into or retract into the fabric drop track. Each swinging actuator cooperates with the corresponding telescopic actuator to form a storage position for placing a fabric roll.

[0009] Both swing devices include swing cylinders, both swing actuators are swing arms, the cylinder bodies of the two swing cylinders are respectively fixedly installed on the front side of the corresponding brackets, and the cylinder bodies of the two swing cylinders are respectively located on the front side of the corresponding swing arms, and the cylinder bodies of the two swing cylinders are respectively close to the connection between the corresponding storage track and the cloth dropping track.

[0010] The free ends of the piston rods of the two swing cylinders are respectively hinged to the front end of the corresponding swing arm, and the cylinder bodies of the two swing cylinders are respectively hinged to the middle part of the corresponding swing arm.

[0011] The rear side of the cylinder body of the two swing cylinders is connected to a mounting protrusion, the front end of the connecting rod is hinged to the mounting protrusion, and the rear end of the connecting rod is hinged to the middle position of the swing arm.

[0012] Each of the swing arms has two connecting rods, and the two connecting rods in each swing arm are arranged opposite to each other.

[0013] The front sides of the two storage tracks are respectively provided with a swing opening one, and the two cloth dropping tracks are respectively provided with a swing opening two. The swing opening one and the swing opening two on each bracket are interconnected and form an L-shape.

[0014] Both of the telescopic devices include telescopic cylinders, the cylinder bodies of the two telescopic cylinders are located on the upper side of the piston rod of the corresponding telescopic cylinder, and the cylinder bodies of the two telescopic cylinders are respectively installed on the upper side of the corresponding fabric drop track.

[0015] A reinforcing member is installed on the upper side of the fabric drop track. The reinforcing member has a through hole, which is located within the extension and retraction range of the piston rod of the telescopic cylinder.

[0016] The piston rod of the telescopic cylinder is connected to a stop for moving in and out of the perforation, and both telescopic actuators are stopes.

[0017] Each of the fabric drop tracks has two corresponding through holes, and the through holes on the reinforcement are on the same straight line as the two corresponding through holes.

[0018] By adopting the above structure, this utility model has the following beneficial effects:

[0019] 1. This utility model employs a combination of a swinging device and a telescopic device. When a new fabric roll needs to fall, the two telescopic actuators move synchronously, causing the fabric roll in the storage position to fall to the rear end of the fabric drop track (i.e., the winding position). Then, the two telescopic actuators extend synchronously, creating an empty storage position again. Subsequently, the two swinging actuators move synchronously, positioning their rear ends between the last fabric roll in the storage track and its adjacent roll. As the two swinging actuators continue to swing, they move the last fabric roll, causing it to fall until it is blocked by the two telescopic actuators. At this point, the two swinging actuators... The moving elements also stop swinging, at which point the last roll of fabric is in the holding position. Compared with the prior art, a roll of fabric is pre-set at the holding position, and the telescopic actuator is only subjected to the weight of this roll of fabric. Therefore, the telescopic actuator is not easy to jam, ensuring the continuity of the winding action and the winding efficiency. Furthermore, the swinging actuator moves the corresponding roll of fabric to the holding position. Even if the weight of multiple rolls of fabric is concentrated on the swinging actuator, the swinging actuator only needs to overcome the rolling friction and inertial force of the rolls of fabric, which greatly reduces the motion resistance and makes the swinging actuator less likely to jam or be damaged, further ensuring the continuity of winding.

[0020] 2. In this utility model, the swing cylinder is paired with a swing arm. The piston rod of the swing cylinder realizes the swing of the swing arm through the lever principle, so that the swing arm can withstand greater force and the swing arm is not easily deformed.

[0021] 3. The combination of a stop block and reinforcement in the telescopic cylinder of this utility model improves the force on the piston rod of the telescopic cylinder, making the piston rod of the telescopic cylinder less prone to deformation (i.e., bending). Attached Figure Description

[0035] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0036] An improved guide roller mechanism for pre-releasing the roll roll in a fabric winding machine is an improvement on a fabric winding machine with a pre-releasing function. The fabric winding machine is Chinese Patent No. CN 113862890 B, entitled "A fabric winding machine with a pre-releasing function".

[0037] like Figure 1As shown - Figure 4 As shown, the fabric rolling machine used in this embodiment includes a fabric rolling base for mounting weaving equipment and a main control device. The fabric rolling base includes a base 11a and supports 12a erected on both sides of the base 11a. A storage mechanism 20a, a fabric dropping mechanism, a fabric pushing mechanism, a fabric rolling mechanism, and a fabric cutting mechanism are installed between the two supports 12a. The storage mechanism and the fabric pushing mechanism are both located above the fabric dropping mechanism, and the fabric rolling mechanism and the fabric cutting mechanism are both located below the fabric dropping mechanism. The fabric dropping mechanism includes two fabric dropping tracks 30a, and the two fabric dropping tracks 30a are paired with the two supports 12a one-to-one. The storage mechanism 20a includes storage tracks 21a respectively installed on the two supports 12a and multiple fabric rolling rollers 22a installed between the two storage tracks.

[0038] The aforementioned main control device includes an operation panel (not shown in the figure) and a control system (not shown in the figure). The operation panel is used to send signals, and the control system is used to receive signals and convert them into results. The control system is used to receive and / or send control signals generated according to configuration information. The control system is electrically connected to the storage mechanism, the fabric rolling mechanism, the fabric cutting mechanism, and the fabric pushing mechanism, respectively. In this embodiment, the main control device adopts a conventional main control device, and its signal reception and control are conventional operations, so they will not be described in detail.

[0039] For ease of description, the conveying direction of the fabric roll in this embodiment is from front to back, and the side of the two supports 12a that corresponds to each other is the inner side, and the side that is opposite to each other is the outer side.

[0040] The improvement of this utility model is that it also includes a stop roller mechanism 100, which is used to control the roll rollers 22a to slide down one by one. The stop roller mechanism 100 includes two swing devices 1 and two telescopic devices 2. The two swing devices 1 are paired with the two supports 12a one-to-one, and the two swing devices 1 are respectively installed on the inner side of the corresponding supports 12a. The two telescopic devices 2 are paired with the two supports 12a one-to-one, and the two telescopic devices 2 are respectively installed on the inner side of the corresponding supports 12a. In this embodiment, the storage track 21a and the fabric drop track 30a on each support 12a are interconnected and together form an L-shape, that is, the storage track 21a and the fabric drop track 30a on each support 12a are connected to each other and together form an L-shape. The connection position is a corner position, and the two together form a track; wherein, each of the two swinging devices 1 includes a swinging actuator 11, the rear part of the two swinging actuators 11 respectively extends into the connection position between the corresponding storage track 21a and the fabric drop track 30a, and swings back and forth at the connection position to push the fabric roll 22a into the fabric drop track 30a; each of the two telescopic devices 2 includes a telescopic actuator 21, and the two telescopic actuators 21 are respectively provided on the corresponding bracket 12a in a manner that can extend into or retract into the fabric drop track 30a; in this embodiment, each swinging actuator 11 and the corresponding telescopic actuator 21 cooperate with each other to form a storage position for placing a fabric roll.

[0041] In this embodiment, the installation structure and arrangement of the swing device 1 and telescopic device 2 on each of the above-mentioned brackets 12a are the same. Therefore, the swing device 1 and telescopic device 2 on one of the brackets 12a are used as an example for explanation.

[0042] Specifically, such as Figure 1 As shown - Figure 3 As shown, the aforementioned swing device 1 includes a swing cylinder 12, and the aforementioned swing actuator 11 is a swing arm. The cylinder body of the swing cylinder 12 is fixedly installed on the inner side of the bracket 12a, and the cylinder body of the swing cylinder 12 is located on the front side of the storage track 21a and near the connection position between the storage track 21a and the cloth dropping track 30a. The swing actuator 11 is located on the rear side of the swing cylinder 12. In this embodiment, the aforementioned swing cylinder 12 is fixed to the inner side of the bracket 12a using a conventional installation method. For example, the inner side of the bracket 12a is equipped with a swing fixing seat 31 using a conventional bolt locking method, and the cylinder body of the swing cylinder 12 is installed on the swing fixing seat 31 using a conventional bolt locking method.

[0043] Furthermore, the swing cylinder 12 in the aforementioned swing device can be a conventional swing cylinder 12 capable of reciprocating swinging, such as a linkage-type swing cylinder or a linear-swing composite cylinder with a square piston rod.

[0044] In addition, the swing cylinder 12 can also be a conventional telescopic cylinder with a transmission structure. That is, the swing cylinder 12 achieves back and forth swinging through the transmission structure. Specifically, the free end of the piston rod of the swing cylinder 12 is hinged to the front end of the swing actuator 11, and a connecting rod 13 is hinged between the cylinder body of the swing cylinder 12 and the middle part of the swing actuator 11. Both hinge structures employ conventional hinge methods. For example, the free end of the piston rod of the swing cylinder 12 has a mounting through hole one, which is arranged in the inward and outward direction. The front end of the swing actuator 11 has a mounting through hole two. Mounting through holes one and two correspond to each other. A first pin 41 is tightly inserted into mounting through hole one, and mounting through hole two is inserted into the first pin, with a clearance fit between mounting through hole two and the first pin 41. Correspondingly, the front end of the connecting rod 13 is hinged to the rear side of the cylinder body of the swing cylinder 12, and the rear end of the connecting rod 13 is hinged to the middle of the swing actuator 11. The hinge structure of both is the same as the hinge structure described above, so it will not be described in detail. Preferably, to ensure the stability of the hinge structure... The front end of the swing actuator 11 is U-shaped. The free end of the piston rod of the swing cylinder 12 extends into the front end of the swing actuator 11. At this time, there are two mounting through holes. The swing actuator 11 is inserted into the same first pin 41 through the two mounting through holes, so as to realize the swing actuator 11 rotating with the first pin as the base point. In addition, the rear side of the cylinder body of the swing cylinder 12 is integrally connected with the mounting protrusion 121. There are two connecting rods 13, which are respectively located on both sides of the telescopic actuator 11 and arranged back to back. The front ends of the two connecting rods 13 are respectively hinged to the mounting protrusion 121 through the second pin 42, and the rear ends of the two connecting rods 13 are respectively hinged to the middle of the swing actuator 11 through the third pin 43.

[0045] Furthermore, the front side of the storage track 21a is provided with a swing opening 51, and the fabric drop track 30a is provided with a swing opening 52. The swing opening 51 and the swing opening 52 are connected to each other, and the swing opening 51 and the swing opening 52 together form an L-shaped swing channel to facilitate the back-and-forth swing of the swing actuator 11. Preferably, the storage track 21a and the fabric drop track 30a are integrally formed structures.

[0046] It is worth mentioning that an angle is formed between the storage track 21a and the fabric drop track 30a, and this angle is arranged according to the actual situation. In this embodiment, the angle between the storage track 21a and the fabric drop track 30a is an obtuse angle, which facilitates the sliding of the fabric roll roller and facilitates the rear part of the subsequent swing actuator to move the fabric roll roller.

[0047] Thus, when the swing cylinder 12 actuates, its piston rod retracts. Due to the action of the two connecting rods, both connecting rods rotate clockwise around the base point of the second pin 42, thereby driving the swing actuator 11 to rotate clockwise around the base point of the first pin 41. This causes the rear part of the swing actuator 11 to extend between two adjacent fabric rolling rollers. Then, the swing cylinder 12 extends, and both connecting rods rotate counterclockwise around the base point of the second pin 42, thereby driving the swing actuator 11 to rotate clockwise around the base point of the first pin 41. The point rotates in the opposite direction to push the fabric roll (i.e., the pre-stored fabric roll) close to the fabric drop track 30a to fall along the track. The oscillating actuator 11 continues to oscillate until it stops oscillating. When the pre-stored fabric roll falls into the space blocked by the telescopic actuator 21 described below, the oscillating actuator 11 and the telescopic actuator 21 together form a storage space, with the pre-stored fabric roll in the storage position. Then the oscillating actuator 11 and the telescopic actuator 21 stop moving until a new fabric roll needs to fall.

[0048] The aforementioned telescopic device 2 includes a telescopic cylinder 22. The cylinder body of the telescopic cylinder 22 is fixedly installed on the upper side of the fabric drop track 30a. The cylinder body of the telescopic cylinder 22 is located above the piston rod of the telescopic cylinder 22, wherein the piston rod of the telescopic cylinder 22 is the aforementioned telescopic actuating element 21. Preferably, the piston rod of the telescopic cylinder 22 is drivenly connected to a stop block, which can be a cylindrical rod. The piston rod of the telescopic cylinder 22 and the stop block are conventionally connected together, for example, the piston rod is tightly inserted into the mounting hole on the stop block. In this embodiment, the stop block is preferably a cylindrical stop block, thus the stop block is the telescopic actuating element 21. In this embodiment, the mounting structure of the cylinder body of the telescopic cylinder 22 adopts a conventional structure, and therefore will not be described in detail.

[0049] Preferably, to prevent deformation of the piston rod of the telescopic cylinder, a reinforcement member 32 is fixedly installed on the upper side of the cloth-felling track 30a. Preferably, the reinforcement member 32 can be a copper sleeve. The reinforcement member 32 has a through hole arranged in the vertical direction. Preferably, the axis of the through hole is arranged perpendicular to the cloth-felling track 30a. The telescopic actuator 21 is inserted into the through hole of the reinforcement member 32. The telescopic actuator 21 can extend and retract along the through hole, that is, the telescopic actuator 21 is adapted to the through hole. The telescopic actuator 21 passes through or is inserted into the through hole under the extension and retraction action of the telescopic cylinder 22.

[0050] Furthermore, the aforementioned fabric drop track 30a has two through holes 61 near the aforementioned connection position. The two through holes 61 correspond to each other, and their shapes and sizes are adapted to the shape and size of the stop block, so that the stop block can extend into or out of the through holes 61. In this way, when the telescopic cylinder 22 extends, its piston rod passes through the two through holes 61 in sequence, thereby driving the telescopic actuator 21 to move, causing the telescopic actuator 21 to block the fabric drop track 30a; after the telescopic cylinder 22 retracts, it drives the telescopic actuator 21 to leave through the two through holes 61, thereby opening the fabric drop track 30a.

[0051] Preferably, the piston rod and the stop block of the telescopic cylinder 22 are arranged coaxially, and the axis of the stop block and the two through holes are on the same straight line, that is, the piston rod of the telescopic cylinder 22 is perpendicular to the upper side of the fabric drop track 30a; in this way, when the fabric roll falls into the retention position, the contact area between the stop block and the fabric roll is maximized, and the fabric roll is better blocked.

[0052] This utility model discloses an improved blocking roller mechanism for pre-releasing the roll roll in a fabric winding machine. When the roll roll at the rearmost side of the storage track 21a falls, i.e., when a new roll roll needs to fall, the two telescopic actuators 11, driven by the telescopic cylinder 12, synchronously retract, causing the roll roll in the storage position to fall to the rear end of the unloading track (i.e., the winding position). Then, the two telescopic actuators 11, under the action of the telescopic cylinder 12, synchronously extend to block the two unloading tracks 30a respectively, so that the two unloading tracks 30a respectively form an empty storage position again. Subsequently, the two... The swing cylinder 22 actuates to drive the respective swing actuators 21 to swing synchronously, so that the rear of the two swing actuators 21 are located between the last roll of fabric (defined as the roll of fabric to be pre-stored) and its adjacent roll of fabric in the storage track 21a. As each swing actuator 21 continues to swing, the roll of fabric to be pre-stored will be moved, so that the roll of fabric to be pre-stored falls to the blocking position of the corresponding telescopic actuator 11. Then the two swing actuators stop swinging respectively. At this time, the roll of fabric to be pre-stored is in the storage position to facilitate the installation of the next new roll of fabric.

[0053] The above description is only a preferred embodiment of this invention. All equivalent changes and modifications made within the scope of the claims of this utility model shall fall within the scope of the claims of this utility model.
