Description

Technical Field

[0001] The utility model relates to the technical field of plastic film production and knitted fabric processing, in particular to a roll-type knitted fabric raw material feeding and conveying equipment. Background Art

[0002] The base fabric of PVC calendered artificial leather is still mainly knitted, and the knitted fabric factory supplies it with tube cloth. The tube cloth needs to be opened and sized in the artificial leather factory, that is, the tube cloth is cut into flat cloth and sized. This base fabric processing equipment is called a cloth opening and sizing machine. However, the traditional knitted tube cloth is solid and does not adopt a central support structure. Therefore, the conventional feeding method adopts a semi-cylindrical material box structure, and a rolling wheel structure is provided at the bottom to assist. In this way, the feeding of the tube cloth can be completed under the rolling action of the tube cloth and the driving cooperation of the traction structure of the cloth opening and sizing machine. However, the structural design of this method is unreasonable, and there is a large friction resistance between the tube cloth and the material box. Furthermore, the rotation of the tube cloth is not a regular circular motion, and the weight of the tube cloth itself is relatively heavy. The traction of the traction structure will cause the unfolded knitted cloth to be tightened. If the rotation of the knitted tube cloth cannot keep up, the large traction force will cause the knitted cloth to be pulled and deformed, and in severe cases, the knitted cloth raw material will be damaged. For this reason, we need a new type of reel-type knitted cloth raw material feeding and conveying equipment. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Example: Figure 1-Figure 4 As shown:

[0022] A roll-type knitted cloth raw material feeding and conveying equipment includes a box body 1, in which a material storage chamber 2 is provided, and the cross section of the material storage chamber 2 is a semicircular structure adapted to the tube cloth; such a configuration is convenient for placing the knitted cloth raw material. A driving member 3 is also installed in the box body 1, and the driving member 3 includes a driving motor 31, a driving wheel 32, a transmission shaft 33 and a driven wheel 34; this part of the structure is arranged in the box body and is located below the material storage chamber. The driving motor 31 is arranged in the box body 1, the driving wheel 32 is arranged on the output shaft of the driving motor 31, the transmission shaft 33 is rotatably arranged in the box body 1, and the driven wheel 34 is sleeved and installed on the transmission shaft 33, and meshes with the driving wheel 32 for transmission; the purpose of such a configuration is to centrally fix the knitted tube cloth, lift the tube cloth raw material, and reduce friction resistance.

[0023] In this embodiment, both ends of the transmission shaft 33 are equipped with rotating screws 5 through transmission members 4, and the side walls of the box body are correspondingly provided with mounting holes, such as Figure 2 As shown: the rotating screw and the box body are matched through a keyway, and the two can rotate relative to each other but cannot move relative to each other. The rotating screw is installed in matching with the mounting hole. The rotating screw 5 extends vertically upward, and the top end is located outside the box body 1; the rotating screw 5 is provided with a relatively rotatable fixed block 6. Figure 2 As shown: the transmission member 4 includes a first bevel gear 41 and a second bevel gear 42; the first bevel gear 41 is arranged on the transmission shaft 33, and the second bevel gear 42 is arranged on the rotating screw 5. The first bevel gear 41 and the second bevel gear 42 are meshed and transmitted, so that the rotating screw 5 drives the fixed block 6 to move up and down. The structural design is reasonable and space-saving. At the same time, the transmission shaft drives the rotating screw to rotate, and then the rotating screw 5 drives the fixed block 6 to move up and down. The driving motor adopts a servo control motor, and through forward and reverse motion, it drives the rotating screw to rotate forward and reverse, so that the fixed block drives the roller to move up and down, which is convenient for knitted tube cloth feeding, and the center height of tube cloths with different diameters and thicknesses can also be adjusted.

[0024] In this embodiment, if Figure 1As shown: a guide rod 9 is also provided between the fixed block 6 and the housing 1; the guide rod 9 is vertically distributed in the housing 1 and passes through the fixed block 6, and the guide rod 9 is slidably connected to the fixed block 6. The guide rod is vertically distributed in the housing, and the two are fixed by welding. The top of the guide rod is kept flush with the top of the rotating screw. The guide rod passes through the fixed block, and the two are slidably connected, which plays a role in circumferential limiting and guiding the up and down movement of the fixed block, and then the fixed block and the rotating screw form a "screw nut" structure to realize the forward and reverse movement of the rotating screw, driving the fixed block to move up and down. The rotating screw 5, the fixed block 6 and the guide rod 9 are two groups that are matched and symmetrically distributed. Such an arrangement ensures symmetry and balanced support force. A protrusion is provided at the top of the rotating screw to prevent the fixed block from moving up and out of position.

[0025] like Figure 2 As shown: In this embodiment, the fixed block 6 is also connected to the roller 8 through the connecting piece 7 to drive the knitted tube cloth to start rotating at a preset speed for conveying. The roller 8 is a cylindrical structure with small ends and a large middle. Figure 4 The structure shown is as follows: the connecting members 7 are two groups symmetrically distributed on the left and right, and each group of the connecting members 7 includes a rotating shaft 71, a base 72 and a fastening plate 73. The rotating shaft 71 is rotatably arranged on the fixed block 6, wherein the bearing capacity of the rotating shaft is large enough. The base 72 is connected to the rotating shaft 71, and a groove 74 of a semicircular structure is arranged inside. One side of the fastening plate 73 is hinged to the base 72, and the other side is connected to the base 72 through a fastening bolt, and a pressing groove 75 of an arc structure is arranged inside the fastening plate 73. A rotating motor 10 is fixedly installed on one of the fixed blocks 6, and the output shaft of the rotating motor 10 is connected to the rotating shaft 71 distributed on one side. The rotating motor adopts a servo control motor, and a control switch 11 is also arranged on the side wall of the box body 1. The control switch 11 is electrically connected to the driving motor 31 and the rotating motor 10 respectively. With such a configuration, the knitted tube cloth is suspended and rotates freely, effectively avoiding the friction resistance of the box body, avoiding the abnormal pulling of the cloth, and improving the integrity and operation efficiency of the knitted cloth feeding.

[0026] Working process: In the initial state, the fixed block 6 is located at the lower part of the rotating screw 5, and the staff inserts the roller 8 into the central reserved gap of the knitted tube cloth and puts it into the storage cavity 2. At this time, the base is located directly below the roller.

[0027] Then the staff starts the corresponding drive motor 31 through the control switch 11, and the drive motor 31 drives the transmission shaft 33 to rotate through the meshing of the main gear and the auxiliary gear. At the same time, the rotation of the transmission shaft 33 will drive the rotating screw 5 to rotate through the cooperation of the first bevel gear 41 and the second bevel gear 42, and the rotating screw 5 and the side wall of the box body 1 can rotate relative to each other but cannot move relative to each other. Figure 1In the structure shown, the rotating screw 5 rotates counterclockwise, which will drive the fixed block 6 to move up along the guide rod and the rotating screw 5 until it moves up to the roller 8 and contacts the base. In the next step, the staff rotates the fastening plate to press the roller and lock it with the fastening bolt to provide a support basis for the free rotation of the subsequent roll structure knitted fabric. In the next step, the rotating motor 10 is started by controlling the switch 11. The rotating motor 10 has three speeds: low speed mode, medium speed mode and high speed mode. It can be freely selected according to the feeding speed of the tube cloth material and the needs of the cloth opening and sizing machine, further ensuring the stability of the knitted fabric feeding. When the previous roll of cloth is about to end, the staff removes the remaining material and connects it with the next roll of knitted cloth through the sewing equipment, and repeats the operation.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
