Description

Technical Field

[0001] The invention belongs to the technical field of raw silk winding, and in particular relates to a material processing device for producing woven bags. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene.

[0003] When producing woven bags, different types of plastic particles (such as polypropylene) and other additives (such as stabilizers, colorants, etc.) need to be evenly mixed; then the mixed plastic raw materials are heated by a high-temperature melt machine and extruded by an extruder to form continuous plastic strips or films. This process also includes the initial shaping of the material; for the hot sheets or films with residual heat just out of the extruder, air or water cooling is required to quickly cool them down and shape them to ensure their shape stability; then they are transported to dry and stretched at the same time, and the long or wide plastic strips are cut into thin filaments of specified width according to the design requirements to facilitate the next weaving operation.

[0004] Among them, after the cut raw silk is inspected and cleaned, the automatic vertical wire winding machine will wind each raw silk individually onto the corresponding spool for winding processing, which is convenient for subsequent standby. However, when a spool is full, the worker needs to remove the spool and replace it with a new one. This operation requires workers to supervise it at all times, and the replacement operation needs to be completed quickly. The degree of automation is low and the operation is cumbersome.

The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] A material processing device for woven bag production, such as Figure 1-Figure 4As shown, it includes a mounting frame 1, a turntable 2 is rotated on the mounting frame 1, and at least two electric winding groups 3 are arranged on the turntable 2. In this embodiment, there are two electric winding groups 3 in total, and the electric winding group 3 is used to support the winding drum 30 and drive the winding drum 30 to rotate and wind up the woven bag raw silk. The turntable 2 is driven to rotate by the rotary drive group, and the rotating turntable 2 will drive the electric winding group 3 to rotate, so that different electric winding groups 3 can be used alternately to continuously wind up the woven bag raw silk, and the rotary drive group is installed on the mounting frame 1; a support frame 41 is provided on the mounting frame 1, and a wire clamp 42 is slidably provided on the support frame 41, and the left part of the wire clamp 42 has a gap for the woven bag raw silk transported from the outside to pass through, and the guide clamp is driven by the linear drive group to reciprocate in the front and rear directions, and the wire clamp 42 that reciprocates back and forth is suitable for driving the woven bag raw silk in its gap to move back and forth along the electric winding group 3, so that the winding drum 30 driven to rotate by the electric winding group 3 is evenly wound in the axial direction. The linear drive group is installed on the support frame 41; when the two electric winding groups 3 are used alternately, the turntable 2 rotates clockwise to drive the electric winding group 3 to rotate, and the electric winding group 3 originally close to the guide clamp will drive the winding drum 30 of the wound woven bag raw yarn to gradually move away from the guide clamp and stop rotating and winding, while the electric winding group 3 originally far away from the guide clamp will drive the winding drum 30 of the unwound woven bag raw yarn to gradually move closer to the guide clamp and start rotating and winding. The woven bag raw silk is cut, and then the end of the woven bag raw silk is wound onto the winding drum 30 of the newly replaced electric winding group 3 for winding; the turntable 2 is connected with the same number of support shafts 51 as the electric winding group 3, and the electric winding group 3 and the support shafts 51 are arranged alternately in the circumferential direction. When two electric winding groups 3 are alternately arranged, the electric winding group 3 that originally wound up the woven bag raw silk will drive the woven bag raw silk to be wound around the support shaft 51 through the winding drum 30, and the support shaft 51 will pull the woven bag raw silk (such as Figure 3As shown in the figure, a cutting knife 52 for cutting the raw yarn of the woven bag slides on the support shaft 51, and the cutting knife 52 is driven by the telescopic driving group to move on the support shaft 51 to extend and retract, and the telescopic driving assembly is installed on the support shaft 51. Initially, the cutting knife 52 is retracted in the electric winding group 3, and the support shaft 51 can normally pull the raw yarn of the woven bag. After the two electric winding groups 3 are alternately completed, the telescopic driving group drives the cutting knife 52 to extend from the support shaft 51 to automatically cut the raw yarn of the woven bag; a U-shaped wire-pulling rod 61 is rotated on the support frame 41, and the rotation range of the wire-pulling rod 61 covers the electric winding group 3 near the wire clamp 42, and a motor 2 62 is installed on the support frame 41, and the output shaft of the motor 2 62 is connected to the wire-pulling rod 61 The two electric winding groups 3 are connected. After the two electric winding groups 3 have been alternated, the control motor 2 62 drives the wire-pushing rod 61 to rotate, so that the wire-pushing rod 61 moves the woven bag silk between the wire clamp 42 and the support shaft 51 clockwise upward, so that the woven bag silk is wound clockwise around the newly replaced electric winding group 3 close to the wire clamp 42. At the same time, the cutting knife 52 completes the cutting of the woven bag silk, so that the newly replaced electric winding group 3 close to the wire clamp 42 can automatically wind up the woven bag silk, and the fault tolerance rate is high. After the winding drum 30 on one electric winding group 3 is full, it can automatically replace the next electric winding group 3 for use, and the operator does not need to manually replace the empty winding drum 30 immediately, and the degree of automation is high.

[0032] like Figure 2 , Figure 5 and Figure 6 As shown, the rotary drive group includes a rotating shaft 21 rotatably arranged on the mounting frame 1, the rotating shaft 21 is connected to the turntable 2, and the rotation of the rotating shaft 21 will drive the turntable 2 to rotate, thereby replacing the two electric winding groups 3, the rotating shaft 21 is connected to a gear 22, a servo motor 23 is installed on the mounting frame 1, and a gear 24 meshing with the gear 1 22 is connected to the output shaft of the servo motor 23, the servo motor 23 is controlled to drive the gear 24 to rotate and mesh with the gear 1 22, the gear 1 22 drives the rotating shaft 21 to rotate, and the diameter of the gear 24 is smaller than that of the gear 1 22.

[0033] like Figure 2 , Figure 7 and Fig. 9 As shown, the electric winding group 3 includes a support roller 31 for supporting the winding drum 30, and the outer side of the support roller 31 is wrapped with a rubber sleeve for increasing the friction between the winding drum 30 and the winding drum 30. The support roller 31 rotates on the turntable 2, and the support roller 31 is driven to rotate by a rotating motor 32. The rotating motor 32 is installed on the turntable 2, and the winding drum 30 for winding up the woven bag raw silk is inserted into the support roller 31, and the rotating motor 32 is controlled to drive the support roller 31 to drive the winding drum 30 to rotate to wind up the woven bag raw silk; in addition, the rotation of the turntable 2 will drive the support roller 31 to rotate through the rotating motor 32, so that the support rollers 31 in the two electric winding groups 3 are used alternately.

[0034] like Figure 4 As shown, the linear drive group includes a bidirectional screw rod 421 rotatably arranged on the support frame 41, and the wire clamp 42 is threadedly connected to the bidirectional screw rod 421. The rotation of the bidirectional screw rod 421 will drive the wire clamp 42 to slide back and forth on the support frame 41. A driving motor 422 is installed on the support frame 41. The output shaft of the driving motor 422 and the bidirectional screw rod 421 are transmitted through a synchronous belt group 423. The driving motor 422 is controlled to drive the bidirectional screw rod 421 to rotate through the synchronous belt group 423, thereby driving the wire clamp 42 to drive the woven bag raw silk to reciprocate; in this embodiment, the synchronous belt group 423 includes two synchronous pulleys respectively connected to the bidirectional screw rod 421 and the output shaft of the driving motor 422, and a synchronous belt meshed between the two synchronous pulleys.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a pressure roller 43, which is used to press the woven bag raw yarn onto the winding drum 30 on the electric winding group 3. The support frame 41 is rotated with a pressure roller 43 on one side close to the electric winding group 3. The support frame 41 is rotatably arranged on the mounting frame 1, and the support frame 41 is driven to rotate by a motor 44. In the process of gradually driving the winding drum 30 to rotate and gradually winding up the woven bag raw yarn, the rotating support frame 41 drives the pressure roller 43 to gradually swing to adjust the pressure roller 43 and the winding drum 30. The spacing between the reels 30 ensures that the pressure roller 43 can both press the woven bag raw silk and not affect the winding of the woven bag raw silk too much. The motor 44 is installed on the mounting frame 1, and the output shaft of the motor 44 is connected to the lower rear side of the support frame 41; in addition, when alternating between the two electric winding groups 3, in order to prevent the pressure roller 43 from affecting the turnover of the electric winding group 3, the motor 44 can be controlled to drive the support frame 41 to drive the pressure roller 43 to swing clockwise, thereby leaving space for the electric winding group 3 to turn around.

[0036] like Figure 5-Figure 8As shown, the telescopic drive group includes a slider 53 slidably arranged on the support shaft 51, and two sliders 53 are connected to the cutting knife 52. The slider 53 and the cutting knife 52 both slide on the turntable 2. A tension spring 54 is connected between the slider 53 and the support shaft 51. The tension spring 54 is used to reset the slider 53 after sliding. A transmission rod 55 is connected to one side of the slider 53. A guide rail 56 concentric with the turntable 2 is connected to the mounting frame 1. The guide rail 56 is for the transmission rod 55 to slide. The guide rail 56 is in the shape of a ring. One side of the guide rail 56 protrudes away from its center to form a deviation portion 561. When the turntable 2 rotates to alternate between the two electric winding groups 3, the support group 53 will be rotated to rotate. The support shaft 51 drives the transmission rod 55 to rotate along the guide rail 56 through the slider 53. When the two electric winding groups 3 are alternately replaced, the transmission rod 55 will rotate to the deviation portion 561 of the guide rail 56. At this time, the deviation portion 561 of the guide rail 56 will squeeze the transmission rod 55 to drive the slider 53 to move away from the support shaft 51. At this time, the slider 53 will drive the cutting knife 52 to extend out from the support shaft 51, so as to automatically and synchronously cut the woven bag raw silk when the two electric winding groups 3 are alternately winding the woven bag raw silk, so that the wire-shifting rod 61 can move the woven bag raw silk to the winding drum 30 of the newly replaced electric winding group 3 for winding in the next step. Each step is interrelated and coordinated with each other.

[0037] like Fig. 9 and Fig.10 As shown, it also includes a switch 33 installed on the rotating motor 32, the switch 33 has a built-in controller, and the built-in controller of the switch 33 is electrically connected to the rotating motor 32. When the switch 33 is pressed, the built-in controller of the switch 33 will control the rotating motor 32 to start, and when the switch 33 is released, the rotating motor 32 is turned off. A resistance ring 34 suitable for squeezing the switch 33 is connected to the mounting frame 1. When two electric winding groups 3 are alternately completed, the turntable 2 will drive the switch 33 in the new electric winding group 3 to rotate until it is squeezed by the resistance ring 34. At this time, the rotating motor 32 in the new electric winding group 3 will drive the winding drum 30 to rotate through the support roller 31 for winding, and the turntable 2 will also drive the switch 33 in the original electric winding group 3 to rotate until it is out of the resistance ring 34. At this time, the rotating motor 32 in the original electric winding group 3 will stop driving the support roller 31 to rotate, so that the winding drum 30 that is fully wound with woven bag raw silk will automatically stop rotating.

[0038] like Fig. 9 and Fig.11As shown, it also includes a mounting seat 71, the front end of the support roller 31 is connected to the mounting seat 71, a stopper 72 for limiting the winding drum 30 on the support roller 31 is rotatable on the mounting seat 71, a torsion spring 73 is connected between the stopper 72 and the mounting seat 71, and a magnetic block 74 suitable for magnetically cooperating with the support roller 31 is embedded on the stopper 72. Under the action of the torsion spring 73, the stopper 72 limits the winding drum 30 on the support roller 31 to improve the stability during winding. When the operator applies force to move the winding drum 30 forward, the winding drum 30 can squeeze The stopper 72 is opened, and the winding drum 30 that is fully wound with the woven bag raw silk is separated from the support roller 31. When the stopper 72 is squeezed open by the original winding drum 30, the magnetic block 74 on the stopper 72 will be magnetically adsorbed on the support roller 31, so as to continue to retract the stopper 72. At this time, the new winding drum 30 can be easily and quickly inserted into the support roller 31, and then the stopper 72 is pushed upward so that the stopper 72 drives the magnetic block 74 to separate from the support roller 31, and the stopper 72 will reset and limit the new winding drum 30 under the action of the torsion spring 73, thereby completing the disassembly and assembly of the winding drum 30.

[0040] It should be pointed out that, for ordinary technicians in this field, several modifications, increases and decreases in quantity, improvements and substitutions can be made without departing from the concept of the present invention. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
