[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that when the above equipment is used, although it can solve the problem that the existing slitting machine cannot fix the membrane cloth during use, when the blade is slitting the membrane cloth, the membrane cloth may be displaced due to the lack of a fixed structure, which in turn affects the slitting quality and is not conducive to people's use.

[0005] However, in actual use, when the above-mentioned equipment fixes the membrane cloth, the operator continuously starts the motor for forward and reverse rotation to complete the up and down movement of the pressure plate. This fixing method not only increases the consumption of electric energy, but also has certain limitations when replacing and maintaining these parts, which is costly. Utility Model Content

[0006] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a positioning component for a slitting machine for protective film production, which has the advantage of positioning and solves the problem that when the above-mentioned equipment fixes the film cloth, the operator continuously starts the motor for forward and reverse operations to complete the up and down movement of the pressure plate. This fixing method not only increases the consumption of electric energy, but also incurs high costs when replacing and maintaining these parts.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning component of a slitting machine for producing protective film, comprising a cylinder, a frame and a cutter, the cylinder being fixedly connected to the top of the frame, the output end of the cylinder being located inside the frame, the cutter being fixedly connected to the output end of the cylinder, a mounting block being fixedly connected to the surface of the output end of the cylinder, connecting plates being fixedly connected to the left and right sides of the surface of the mounting block, a positioning rod being arranged on the outer side of the bottom of the connecting plate, a collapse assembly being provided at the bottom of the positioning rod, and an adjustment assembly being fixedly connected to the top of the positioning rod.

[0008] As a preferred embodiment of the utility model, the collapse component includes a collapse hole, the collapse hole is opened at the bottom of the positioning rod, and the interior of the collapse hole is slidably connected with a telescopic rod.

[0009] As a preferred embodiment of the present invention, the adjustment assembly includes a screw rod, which is fixedly connected to the top of the positioning rod, and an adjustment groove is opened on the top of the connecting plate. The screw rod is located inside the adjustment groove, and a nut is threadedly connected to the surface of the screw rod.

[0010] As a preferred embodiment of the present invention, an expansion block is fixedly connected to the bottom of the telescopic rod, and the diameter of the expansion block is larger than the diameter of the telescopic rod.

[0011] As a preferred embodiment of the utility model, the bottom of the positioning rod surface is fixedly connected to a limiting block, the surface of the telescopic rod is sleeved with a spring, the top of the spring is fixedly connected to the limiting block, and the bottom of the spring is fixedly connected to the expansion block.

[0012] As a preferred embodiment of the utility model, a protective pad is pasted on the bottom of the enlarged block, and the material of the protective pad is natural rubber.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides a mounting block, a connecting plate, a positioning rod and a collapse assembly. When processing a workpiece, the output end of the cylinder drives the cutter to move downward. While the cutter moves, the output end of the cylinder drives the connecting plate to move downward through the mounting block. Since the bottom height of the collapse assembly is lower than the height of the cutter, the connecting plate drives the collapse assembly to contact the workpiece through the positioning rod, thereby completing the fixation of the workpiece. When the cutter contacts the workpiece, the collapse assembly collapses toward the inside of the positioning rod to prevent the telescopic rod from affecting the normal operation of the cutter. This solves the problem that when the above-mentioned equipment fixes the membrane cloth, the operator continuously starts the motor for forward and reverse rotation to complete the up and down movement of the pressing plate. This fixing method not only increases the consumption of electric energy, but also increases the cost when these parts are replaced and maintained. The positioning effect is achieved.

[0016] 2. The utility model sets a collapse component. When the connecting plate drives the positioning rod to move downward, the positioning rod drives the telescopic rod to move to contact and fix with the workpiece. When the telescopic rod contacts the workpiece, the telescopic rod will collapse into the collapse hole as the connecting plate continues to move downward until the cutting is completed by the cutting knife, thereby ensuring the stability of the workpiece positioning.

[0017] 3. The utility model provides an adjustment component. When the operator needs to fix the size of the workpiece, the operator loosens the nut and then freely moves the positioning position of the positioning rod through the adjustment slot, thereby ensuring the convenience of adjustment by the operator. When the positioning rod is moved to a suitable position, the operator tightens the nut so that the nut locks the positioning rod through the screw, thereby ensuring the stability of the positioning rod.

[0022] 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.

[0023] like Figures 1 to 3 As shown, the utility model provides a positioning component of a slitting machine for protective film production, comprising a cylinder 1, a frame 2 and a cutter 3, the cylinder 1 is fixedly connected to the top of the frame 2, the output end of the cylinder 1 is located inside the frame 2, the cutter 3 is fixedly connected to the output end of the cylinder 1, a mounting block 4 is fixedly connected to the surface of the output end of the cylinder 1, a connecting plate 5 is fixedly connected to the left and right sides of the surface of the mounting block 4, a positioning rod 6 is arranged on the outer side of the bottom of the connecting plate 5, a collapse component 7 is provided at the bottom of the positioning rod 6, and an adjustment component 8 is fixedly connected to the top of the positioning rod 6.

[0024] refer to Figure 3 The collapse assembly 7 includes a collapse hole 71 , which is opened at the bottom of the positioning rod 6 , and a telescopic rod 72 is slidably connected to the interior of the collapse hole 71 .

[0025] As a technical optimization scheme of the utility model, by setting the collapse component 7, when the connecting plate 5 drives the positioning rod 6 to move downward, the positioning rod 6 drives the telescopic rod 72 to move to contact and fix with the workpiece. When the telescopic rod 72 contacts with the workpiece, the telescopic rod 72 will collapse into the collapse hole 71 as the connecting plate 5 continues to move downward until the cutting of the cutter 3 is completed, thereby ensuring the stability of the workpiece positioning.

[0026] refer to Figure 3 The adjustment assembly 8 includes a screw 81, which is fixedly connected to the top of the positioning rod 6. An adjustment groove 82 is opened on the top of the connecting plate 5. The screw 81 is located inside the adjustment groove 82. A nut 83 is threadedly connected to the surface of the screw 81.

[0027] As a technical optimization scheme of the utility model, by setting the adjustment component 8, when the operator needs to fix the size of the workpiece, the operator loosens the nut 83, and then the operator can freely move the positioning position of the positioning rod 6 through the adjustment slot 82, thereby ensuring the convenience of the operator's adjustment. When the positioning rod 6 moves to a suitable position, the operator tightens the nut 83, so that the nut 83 locks the positioning rod 6 through the screw 81, thereby ensuring the stability of the positioning rod 6.

[0028] refer to Figure 3The bottom of the telescopic rod 72 is fixedly connected with an expansion block 9 , and the diameter of the expansion block 9 is larger than the diameter of the telescopic rod 72 .

[0029] As a technical optimization solution of the utility model, by setting the expansion block 9, the expansion block 9 and the telescopic rod 72 are fixedly installed, so that the expansion block 9 can increase the contact area between the telescopic rod 72 and the workpiece, so that the telescopic rod 72 can be more stable when fixed.

[0030] refer to Figure 3 The bottom of the surface of the positioning rod 6 is fixedly connected to the limiting block 10, the surface of the telescopic rod 72 is sleeved with a spring 11, the top of the spring 11 is fixedly connected to the limiting block 10, and the bottom of the spring 11 is fixedly connected to the expansion block 9.

[0031] As a technical optimization solution of the utility model, by setting a limit block 10 and a spring 11, when the telescopic rod 72 collapses, the spring 11 will enter a compressed state through the limit block 10 and the expansion block 9, and then the spring 11 will press against the expansion block 9, thereby ensuring the fixing effect of the telescopic rod 72.

[0032] refer to Figure 3 A protective pad 12 is pasted on the bottom of the enlarged block 9, and the material of the protective pad 12 is natural rubber.

[0033] As a technical optimization solution of the utility model, a protection pad 12 is provided and adhered to the bottom of the enlarged block 9, so that the protection pad 12 protects the workpiece when the enlarged block 9 contacts the workpiece to avoid crushing of the workpiece.

[0034] refer to Figure 3 The bottom of the protection pad 12 is provided with anti-skid grooves 13, and a plurality of anti-skid grooves 13 are provided and are distributed at equal distances.

[0035] As a technical optimization solution of the utility model, by providing anti-skid grooves 13, when the protection pad 12 contacts the workpiece, the anti-skid grooves 13 can increase the friction between the protection pad 12 and the workpiece, thereby preventing the protection pad 12 from slipping.

[0036] The working principle and use process of the utility model are as follows: during use, when the operator needs to process the workpiece, the operator places the workpiece at the bottom of the cutter 3, and the operator starts the cylinder 1, and the output end of the cylinder 1 drives the cutter 3 to move downward. While the cutter 3 moves, the output end of the cylinder 1 drives the connecting plate 5 to move downward through the mounting block 4. Since the bottom height of the telescopic rod 72 is lower than the height of the cutter 3, the connecting plate 5 drives the telescopic rod 72 and the enlarged block 9 and the protective pad 12 at the bottom of the telescopic rod 72 to contact the workpiece through the positioning rod 6, thereby completing the fixation of the workpiece. When the cutter 3 contacts the workpiece, the telescopic rod 72 will collapse toward the inside of the positioning rod 6 through the collapse hole 71 to avoid the telescopic rod 72 from collapsing. The rod 72 affects the normal operation of the cutter 3. At the same time, when the telescopic rod 72 is collapsed, the spring 11 will enter a compressed state through the limit block 10 and the expansion block 9, and then the spring 11 will press against the expansion block 9, thereby ensuring the fixing effect of the telescopic rod 72, and then ensuring the stability of the workpiece positioning. When the operator needs to fix the size of the workpiece, the operator loosens the nut 83, and then the operator can freely move the positioning position of the positioning rod 6 through the adjustment slot 82, ensuring the convenience of the operator's adjustment. When the positioning rod 6 moves to a suitable position, the operator tightens the nut 83, so that the nut 83 locks the positioning rod 6 through the screw 81, ensuring the stability of the positioning rod 6.

[0037] To sum up: the positioning component of the slitting machine for protective film production is provided with a mounting block 4, a connecting plate 5, a positioning rod 6 and a collapse component 7. When the workpiece is processed, the output end of the cylinder 1 will drive the cutter 3 to move downward. While the cutter 3 moves, the output end of the cylinder 1 will drive the connecting plate 5 to move downward through the mounting block 4. Since the bottom height of the collapse component 7 is lower than the height of the cutter 3, the connecting plate 5 will drive the collapse component 7 to contact the workpiece through the positioning rod 6, thereby completing the fixation of the workpiece. When the cutter 3 contacts the workpiece, the collapse component 7 will collapse into the inside of the positioning rod 6 to prevent the telescopic rod 72 from affecting the normal operation of the cutter 3. This solves the problem that when the above-mentioned equipment fixes the film cloth, the operator continuously starts the motor for forward and reverse operations to complete the up and down movement of the pressure plate. This fixing method not only increases the consumption of electric energy, but also has a high cost when these parts are replaced and maintained.
