Description

Technical Field

[0001] The utility model relates to the field of non-woven bags, in particular to a non-woven bag punching device. Background Art

[0002] Non-woven bags are environmentally friendly reusable bags that are often used for shopping, packaging and promotional activities. They are made of polypropylene fibers or other fibers, which are made by heat pressing, chemical treatment or mechanical processing instead of traditional weaving or weaving. Non-woven bags are increasingly popular among consumers because of their wear-resistant, tear-resistant and washable characteristics.

[0003] Similar to high-end paper bags, in order to make the exterior more beautiful, the handle part of the non-woven bag will be installed separately, that is, a more beautiful belt or drawstring is used as a handle to be used in conjunction with the non-woven bag. Compared with the one-piece non-woven bag, the cost is increased but the appearance is better. To insert the handle, the non-woven bag needs to be punched. After the hole is formed, the handle can be inserted to complete the installation. However, the non-woven bag is different from the traditional paper bag material. It is lighter and is very easy to move with the punching drill bit during punching. In addition, due to its non-woven material, the punched part is often stretched or torn by the drill bit during punching, resulting in cracks at the edge of the hole after the punching is completed. The crack becomes larger and is easily damaged during subsequent use. Summary of the invention

[0004] 1. Technical issues to be resolved

[0024] See also Figure 1-3A non-woven bag punching device shown in the figure includes a workbench 1, a base 2 is provided on the workbench 1, a rocker-type lifting rod assembly 3 is provided on the base 2, a puncher 4 is provided on one side of the rocker-type lifting rod assembly 3, the puncher 4 is fixedly connected to the rocker-type lifting rod assembly 3, and a cutter head 4a is provided on the puncher 4. The workbench 1 includes a table top 1a and a working chamber 1b, a punching channel 1c is provided on the table top 1a, a hydraulic cylinder 5 is provided in the working chamber 1b, a receiving block 6 is provided on the hydraulic rod of the hydraulic cylinder 5, and one end of the receiving block 6 extends into the punching channel 1c, a foot switch 7 is provided on one side of the workbench 1, a slide rail 8 is provided on the table top 1a, a pressing assembly 9 is provided in the slide rail 8, and the pressing assembly 9 includes a movable slider 9a, a pressing bolt 9b and a contact gasket 9c.

[0025] The rocker-type lifting rod assembly 3 includes a lifting column 3a, a lifting slide 3b, and a hand-cranked wheel 3c. The puncher 4 is fixed on one side of the lifting slide 3b. The puncher 4 is fixedly connected to the rocker-type lifting rod assembly 3 through the lifting slide 3b. The rocker-type lifting rod 3, also known as the hand-cranked lifting device assembly, is an existing traditional lifting device and will not be described in detail herein. It also includes components such as a safety lock. The main principle is to manually shake the hand-cranked wheel 3c to drive the lifting slide 3b to rise or fall on the lifting column 3a, thereby driving the puncher 4 to rise and fall. During the process of punching holes in the non-woven bag, the staff holds the hand-cranked wheel 3c to slowly descend, driving the cutter head 4a to gently contact the punching part of the non-woven fabric, thereby reducing the pulling force and the risk of tearing at the punching part.

[0026] The cutter head 4a and the punching channel 1c are coaxially arranged, and the cutter head 4a is arranged directly above the punching channel 1c. The cutter head 4a is aligned with the punching channel 1c. Under normal conditions, the receiving block 6 is supported by the hydraulic cylinder 5 and is arranged in the punching channel 1c, and is kept horizontal with the table 1a. When the non-woven bag needs to be punched, the part of the non-woven bag that needs to be punched is placed on the punching channel 1c, and is clamped by the pressing component 9. At this time, the non-woven bag is between the receiving block 6 and the cutter head 4a, and the punching machine 4 is started. The staff slowly descends by holding the hand-cranked wheel 3c, and the cutter head 4a contacts and slowly penetrates the non-woven bag while contacting the surface of the receiving block 6. At this time, the staff steps on the foot switch 7 to drive the hydraulic cylinder 5 to slowly contract. Under the drive, the receiving block 6 also sinks along the punching channel 1c, and receives the cutter head 4a to enter the punching channel 1c. The receiving block 6 is always used to receive the cutter head 4a and limit it to prevent it from sinking quickly, and to prevent the cutter head 4a from sinking too quickly, causing excessive punching force to tear and pull the non-woven bag and damage it.

[0027] A fixing plate is provided at the bottom of the hydraulic cylinder 5, and the hydraulic cylinder 5 is fixed in the working chamber 1b. A reinforcing rib 5a is provided at the bottom of the hydraulic cylinder 5. The fixing plate and the reinforcing rib 5a are both used to fix the hydraulic cylinder 5 to stabilize it.

[0028] The receiving block 6 is made of cylindrical stainless steel. The receiving block 6 is fixedly connected to the hydraulic rod of the hydraulic cylinder 5. A reinforcing ring 10 is provided at the connection between the receiving block 6 and the hydraulic rod of the hydraulic cylinder 5. The receiving block 6 is driven by the hydraulic rod of the hydraulic cylinder 5 and is reinforced at the connection between the two by the reinforcing ring 10.

[0029] The foot switch 7 is electrically connected to the hydraulic cylinder 5. The function of the foot switch 7 is to control the contraction of the hydraulic cylinder 5 by stepping on it, and the hydraulic cylinder 5 is slowly reset by lifting it.

[0030] The movable slider 9a is L-shaped, and the bottom of the movable slider 9a is arranged in the slide rail 8. The movable slider 9a is provided with a threaded hole. The pressing bolt 9b is threadedly connected to the movable slider 9a. A tightening valve 9d is provided at one end of the pressing bolt 9b. The contact gasket 9c is made of rubber. The movable slider 9a can be moved in the slide rail 8 by pushing, and can be slid and adjusted in the slide rail 8 according to the punching position of the non-woven bag. After the position is suitable, the side of the non-woven bag that needs to be punched is laid on the table 1a, and the pressing bolt 9b is controlled to be pressed down by grabbing and tightening the valve 9d, and the non-woven bag or non-woven fabric is pressed and fixed on the table 1a through the contact gasket 9c to prevent the non-woven bag from being displaced by the rotation of the cutter head 4a during the punching process.

[0031] The specific working principle is: place the non-woven fabric or non-woven bag to be punched on the table 1a, adjust the pressing component 9 to the appropriate position to align and press it down to fix it, start the puncher 4, and drive the puncher 4 to slowly press down through the hand-cranked wheel 3c, and after contacting the punching part of the non-woven fabric, step on the foot switch 7 to control the receiving block 6 to receive and sink the cutter head 4a to drill a hole. During the process, the sinking speed of the cutter head 4a is limited to reduce the tearing of the holes in the non-woven bag caused by excessive punching impact.
