Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of film processing devices, in particular to an anti-static stretch film processing device. Background Art
[0002] Stretch film is a thin film material with strong tensile properties. It is widely used in packaging, civil engineering, agriculture and other fields. It has good tensile properties and the advantages of moisture resistance and corrosion resistance. The production process of stretch film mainly includes four steps: raw material selection, extrusion film formation, stretching and winding.
[0003] The common stretch film processing process on the market first melts the selected raw materials at high temperature and then extrudes them through the screw of the extruder to form a continuously extending film. The film is then stretched by synchronous rollers and stretching rollers to change the structure and performance of the film, thereby improving the ductility and mechanical strength of the film. Finally, the width and length of the wound film are adjusted by the winder according to different specifications and requirements to ensure that the winding is firm and smooth. There are some inconveniences in actual operation and there is room for improvement. For example, when the stretch film is wound in the later stage of processing, very large static electricity will accumulate due to factors such as tension and friction. In severe cases, the charged product may even cause air discharge due to ultra-high potential and cause a fire. It does not have the function of preventing static electricity.
[0004] Now, a novel antistatic stretch film processing device is proposed to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide an anti-static stretch film processing device to solve the problem of anti-static function proposed in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-static stretch film processing device, comprising a frame, wherein rollers are sequentially arranged above the bottom end of the frame, a mother roll is sleeved on the outside of the rollers, a driven roller, a fixed roller and a winding shaft are respectively arranged above the mother roll, a reel is sleeved on the outside of the winding shaft, and a strip component that can prevent static electricity is arranged in front of the frame.
[0007] The strip-shaped component includes an electrostatic eliminator, which is movably connected to the front of the rack. The left and right sides of the front end of the rack are respectively fixedly connected with fixed blocks, the front end of the fixed block is fixedly connected with a strip slide, the inside of the strip slide is movably connected with a locking buckle, the locking buckle is fixedly connected to a slider on the side far from the electrostatic eliminator, the bottom end of the electrostatic eliminator is fixedly connected to a base, and two sets of connecting frames are respectively provided on the left and right sides of the bottom end of the base.
[0008] Preferably, the strip chute is symmetrically distributed about the vertical center line of the frame, the shape and size of the bottom end of the slider are adapted to the shape and size of the inside of the strip chute, and the slider can slide up and down inside the strip chute.
[0009] Preferably, the connecting frame is symmetrically distributed about the vertical center line of the base, and the base and the static eliminator are bolted together.
[0010] Preferably, the connecting frame and the slider are connected, and there is a distance between the static eliminator and the driven roller and the fixed roller.
[0011] Preferably, the left and right sides of the frame are respectively fixedly connected to the limiting blocks, the top of the limiting block is fixedly connected to the first positioning rod, two groups of cutting knives are arranged on the outside of the first positioning rod, the top of the limiting block is fixedly connected to the second positioning rod, and the inside of the second positioning rod is provided with multiple groups of grooves.
[0012] Preferably, the cutters are symmetrically distributed about the vertical center line of the first positioning rod, the vertical center lines of the second positioning rod and the first positioning rod coincide with each other, and the grooves are arranged at equal intervals.
[0013] Preferably, a hollow vertical frame is fixedly connected to the left side of the top of the rack, a cross bar is provided inside the hollow vertical frame, a monitoring head is sleeved on the outside of the cross bar, a wiring socket is provided on the top of the monitoring head, and a signal light is provided at the rear of the hollow vertical frame.
[0014] Preferably, the wiring socket, the monitoring head and the signal light are electrically connected, and there is a distance between the monitoring head and the reel.
[0015] Compared with the prior art, the beneficial effects of the present invention are: the anti-static stretch film processing device not only realizes the function of preventing static electricity, but also realizes the function of preventing burrs and the function of monitoring stretching;
[0016] (1) The static eliminator, connecting frame, base, slider, locking buckle, fixed block and strip chute are provided. The stretch film material is squeezed by the driven roller and fixed roller outside the mother roll to form a continuously extending film. The film is then stretched by the fixed roller and the winding shaft to change the structure and performance of the film. Finally, when the roll is kept rotating to the set winding number, the winder automatically stops working and the operator removes the roll. Since the driven roller is above the mother roll when the stretch film is wound, two sets of fixed blocks are provided at the front end of the frame. The slider drives the base on the connecting frame to slide inside the strip chute. At the same time, the static eliminator can be driven to the winding joint. When the position is determined, it is fixed in the strip chute by the locking buckle so that the static eliminator can be fixed in front of the mother roll and the driven roller. After the static eliminator and the frame are powered on and turned on, the static electricity at any position that rubs against the stretch film can be neutralized, thereby preventing the static electricity caused by the friction between the stretch film winder and the fabric during operation, thereby realizing the function of preventing static electricity.
[0017] (2) By setting a limit block, a first positioning rod, a cutter, a second positioning rod, and a groove, when the stretch film material passes through the driven roller and the fixed roller outside the mother roll, it further passes through the second positioning rod in front of it. Two sets of cutters are riveted to the outside of the first positioning rod inside the limit block, and the bottom ends of the cutters are in the same position as the multiple sets of grooves outside the second positioning rod below it. When the stretch film passes between the second positioning rod and the cutter, the cutter can lock the top end and the groove of the stretch film to make the stretch film flatter, thereby reducing the probability of burrs appearing during the stretching of the stretch film material before being sent to the reel. The stretch film thus obtains a better flattening effect, the processing device has a higher yield rate, and the function of preventing burrs is achieved;
[0018] (3) By setting up a hollow stand, a cross bar, a terminal block, a monitoring head, and a signal light, when in use, the stretch film material is wound from the mother roll through the driven roller and the fixed roller to the outside of the input roll. During the overall operation of the stretch film processing device, a hollow stand is set at the top of the left side of the frame. The monitoring head connected to the outside of the cross bar inside the hollow stand is located in the middle position above the roll. When the stretch film passes over the roll, the monitoring head monitors and photographs it. When it is tracked that the roll below is offset or the processing device is partially damaged and stops working, the signal is transmitted to the operator through the signal light, thereby preventing the overall work progress from being delayed due to damage to the device, extending the service life of the equipment, and realizing the function of monitoring stretching.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Example 1: Please refer to Figure 1-4 An anti-static stretch film processing device includes a frame 1, a rotating roller 2 is sequentially arranged above the bottom end of the frame 1, a mother roll 3 is sleeved on the outside of the rotating roller 2, a driven roller 4, a fixed roller 5 and a winding shaft 6 are respectively arranged above the mother roll 3, a reel 7 is sleeved on the outside of the winding shaft 6, and a strip component for preventing static electricity is arranged in front of the frame 1;
[0026] See also Figure 1-4 , an anti-static stretch film processing device also includes a strip component, the strip component includes an electrostatic eliminator 8, the electrostatic eliminator 8 is movably connected and arranged in front of the frame 1, the left and right sides of the front end of the frame 1 are respectively fixedly connected with fixed blocks 13, the front end of the fixed block 13 is fixedly connected with a strip chute 14, the inside of the strip chute 14 is movably connected with a locking buckle 12, the locking buckle 12 is fixedly connected to the side of the electrostatic eliminator 8 far from the slider 11, the bottom end of the electrostatic eliminator 8 is fixedly connected to a base 10, and two groups of connecting frames 9 are respectively provided on the left and right sides of the bottom end of the base 10;
[0027] The strip chute 14 is symmetrically distributed about the vertical center line of the frame 1. The shape and size of the bottom end of the slider 11 are adapted to the shape and size of the interior of the strip chute 14. The slider 11 can slide up and down inside the strip chute 14. The connecting frame 9 is symmetrically distributed about the vertical center line of the base 10. The base 10 and the static eliminator 8 are bolted together. The connecting frame 9 and the slider 11 are connected. There is a distance between the static eliminator 8 and the driven roller 4 and the fixed roller 5.
[0028] Specifically, if Figure 1 and Figure 2 As shown, the stretch film material is squeezed by the driven roller 4 and the fixed roller 5 outside the mother roll 3 to form a continuously extending film, and then stretched by the fixed roller 5 and the winding shaft 6 to change the structure and properties of the film. Finally, when the film is wound to the set winding number through the reel 7, the winder automatically stops working and the operator removes the reel 7. Since the driven roller 4 is above the mother roll 3 when the stretch film is wound, two sets of fixed blocks 13 are provided at the front end of the frame 1. The slider 11 drives the base 10 on the connecting frame 9 to slide inside the strip slide 14, and at the same time, the static eliminator 8 can be driven to the winding joint. When the position is determined, it is fixed in the strip slide 14 by the locking buckle 12 so that the static eliminator 8 can be fixed in front of the mother roll 3 and the driven roller 4. After the static eliminator 8 and the frame 1 are energized and turned on as a whole, the static electricity at any position that rubs against the stretch film can be neutralized, thereby preventing the static electricity caused by the friction between the stretch film winder and the fabric during operation, and the anti-static effect is better.
[0029] Example 2: The left and right sides of the frame 1 are respectively fixedly connected to the limit blocks 15, the top of the limit block 15 is fixedly connected to the first positioning rod 16, two groups of cutters 17 are provided on the outside of the first positioning rod 16, the top of the limit block 15 is fixedly connected to the second positioning rod 18, and the second positioning rod 18 is provided with multiple groups of grooves 19. The cutters 17 are symmetrically distributed about the vertical center line of the first positioning rod 16, the vertical center lines of the second positioning rod 18 and the first positioning rod 16 coincide with each other, and the grooves 19 are arranged at equal intervals;
[0030] Specifically, if Figure 1 and Figure 3 As shown, when the stretch film material passes through the driven roller 4 and the fixed roller 5 on the outside of the mother roll 3, it further passes through the second positioning rod 18 in front of it. The first positioning rod 16 inside the limit block 15 is riveted with two groups of cutters 17 on the outside, and the bottom end of the cutter 17 and the multiple groups of grooves 19 on the outside of the second positioning rod 18 below it are in the same position. When the stretch film passes between the second positioning rod 18 and the cutter 17, the cutter 17 can lock the top end of the stretch film and the groove 19 to make the stretch film smoother, reducing the probability of burrs appearing during the stretching of the stretch film material before being sent to the reel 7. The stretch film therefore obtains a better flattening effect and the processing device has a higher yield rate.
[0031] Embodiment 3: A hollow stand 20 is fixedly connected to the left side of the top of the frame 1. A crossbar 21 is provided inside the hollow stand 20. A monitoring head 23 is sleeved on the outside of the crossbar 21. A wiring socket 22 is provided on the top of the monitoring head 23. A signal light 24 is provided at the rear of the hollow stand 20. The wiring socket 22, the monitoring head 23 and the signal light 24 are electrically connected. There is a distance between the monitoring head 23 and the reel 7.
[0032] Specifically, if Figure 1 and Figure 4 As shown, when in use, the stretch film material is wound from the mother roll 3 through the driven roller 4 and the fixed roller 5 to the outside of the input roll 7. During the overall operation of the stretch film processing device, a hollow stand 20 is provided at the top of the left side of the frame 1. The monitoring head 23 connected to the outside of the cross bar 21 inside the hollow stand 20 is located in the middle position above the roll 7. When the stretch film passes over the roll 7, the monitoring head 23 monitors and photographs it. When it is tracked that the roll 7 below is offset or the processing device is partially damaged and stops working, the signal is transmitted to the operator through the signal light 24 to prevent the overall work progress from being delayed due to damage to the device, thereby improving work efficiency.
[0033] Working principle: When the utility model is in use, first, the stretch film material is squeezed outside the mother roll 3 by the driven roller 4 and the fixed roller 5 to form a continuously extended film, and then stretched by the fixed roller 5 and the winding shaft 6 to change the structure and performance of the film. Finally, when the winding drum 7 keeps rotating to the set winding number, the winder automatically stops working and the operator removes the drum 7. Since the driven roller 4 is above the mother roll 3 when the stretch film is wound, two sets of fixed blocks 13 are set at the front end of the frame 1. The slider 11 drives the base 10 on the connecting frame 9 in the inner of the strip slide 14. The static eliminator 8 can be driven to the winding joint at the same time. When the position is determined, it is fixed in the strip slide 14 by the locking buckle 12 so that the static eliminator 8 can be fixed in front of the mother roll 3 and the driven roller 4. After the static eliminator 8 and the frame 1 are powered on and turned on as a whole, the static electricity at any position that rubs against the stretch film can be neutralized to prevent the static electricity caused by the friction with the fabric during the operation of the stretch film winding machine. The anti-static effect is better. When the stretch film material passes through the driven roller 4 and the fixed roller 5 outside the mother roll 3, it further passes through the second positioning rod 1 in front of it. 8. Two sets of cutters 17 are riveted to the outside of the first positioning rod 16 inside the limit block 15, and the bottom end of the cutter 17 is aligned with the multiple sets of grooves 19 outside the second positioning rod 18 below it. When the stretch film passes between the second positioning rod 18 and the cutter 17, the cutter 17 can lock the top of the stretch film and the groove 19 to make the stretch film smoother, reducing the probability of burrs appearing during the stretching of the stretch film material before being sent to the reel 7. The stretch film thus obtains a better flattening effect, and the processing device has a higher yield rate. When in use, the stretch film material passes from the mother roll 3 through the driven roller 4 The fixed roller 5 is finally wound onto the outside of the input reel 7. During the overall operation of the stretch film processing device, a hollow stand 20 is provided at the top left side of the frame 1. The monitoring head 23 connected to the outside of the cross bar 21 inside the hollow stand 20 is located in the middle position above the reel 7. When the stretch film passes over the reel 7, the monitoring head 23 monitors and photographs it. When it is tracked that the reel 7 below is offset or the processing device is partially damaged and stops working, the signal is transmitted to the operator through the signal light 24 to prevent the overall work progress from being delayed due to damage to the device, thereby improving work efficiency.
