Description

Technical Field

[0001] The utility model relates to the technical field of automatic slitting machines for woven bags, and specifically to a specification adjusting mechanism for an automatic slitting machine for woven bags. Background Art

[0002] A woven bag is a type of plastic bag used for packaging, and its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. A woven bag slitting machine is a mechanical device mainly used to unwind and convey a woven bag roll material to a cutting device to achieve the cutting of the woven bag. The purpose of slitting the woven bag is to divide a whole roll of woven bag into multiple groups of fabrics. Most slitting devices for woven bags use hot cutting devices. By heating the hot cutting knife, the cut end position of the woven bag is made flat to prevent the phenomenon of wire drawing, and at the same time, the hot cutting knife cuts the woven bag more quickly.

[0003] When slitting a woven bag, it is necessary to adjust the distance between two adjacent hot cutting knives according to the required slitting width. When adjusting the existing distance between hot cutting knives, it mostly relies on manual visual inspection. On the one hand, the error generated by the adjustment is increased, and on the other hand, it is more inconvenient to adjust two adjacent groups of hot cutting knives. For this reason, a specification adjusting mechanism for an automatic slitting machine for woven bags is proposed. By rotating the screw rod, the two rotating rods slide in opposite directions, so that the hot cutting knives fixed at the outer ends of the mounting plates slide to solve the above problems. Summary of the Utility Model

[0004] The utility model provides a specification adjusting mechanism for an automatic slitting machine for woven bags, which solves the problems of large adjustment error and complex operation in adjusting the distance between two adjacent hot cutting knives.

[0005] The technical solution of the utility model is as follows:

[0006] A specification adjusting mechanism for an automatic slitting machine for woven bags includes side plates. There are two groups of the side plates. A support column is fixedly connected between the two groups of side plates. An adjusting component is arranged at the outer end of the support column. The adjusting component includes mounting plates symmetrically and slidably connected to the outer end of the support column. A fixed claw is fixedly connected to one side of the mounting plate. A rotating rod is rotatably connected inside the fixed claw. A connecting piece is rotatably connected between the two rotating rods. A screw rod is threadedly connected inside the connecting piece. A hot cutting component is arranged on the side of the mounting plate away from the fixed claw.

[0007] Preferably, the adjusting component further includes a support rod fixedly connected between the two groups of side plates. The screw rod is threadedly connected to the support rod.

[0008] Preferably, there are four groups of support columns arranged in a square. The support rod is arranged between the four groups of support columns, and the support rod penetrates through the mounting plate.

[0009] Preferably, the hot cutting component includes a connecting frame fixedly connected to the side end of the mounting plate. A hot cutting knife is clamped inside the connecting frame, a clamping groove is formed inside the hot cutting knife, and a heating rod is clamped inside the clamping groove.

[0010] Preferably, a bottom frame is fixedly connected to the bottom end of the side plate. A support rod is fixedly connected between the two bottom frames. A clamping plate is slidably connected to the outer end of the support rod, and the clamping plate corresponds to the position of the hot cutting knife.

[0011] Preferably, a cutting groove is formed inside the clamping plate. The cross sections of the hot cutting knife and the cutting groove are both V-shaped. The support rod is perpendicular to the hot cutting knife, and the support rod is arranged at the central position of the hot cutting knife.

[0012] Preferably, grooves are symmetrically formed at the top end of the clamping plate, and rollers are rotatably connected inside the grooves.

[0013] Preferably, a lock is threadedly connected inside the clamping plate, and one end of the lock abuts against the support rod.

[0014] The working principle and beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, by rotating the screw rod, the rotating rod drives the mounting plate to slide on the outer end of the support column, so that the two mounting plates drive the hot cutting knives at their outer ends to slide in an equidistant and reverse manner. The error generated by adjusting the distance between two adjacent hot cutting knives is small, so that the widths of multiple cloth bags after cutting the woven bag are the same. At the same time, the distance between the two hot cutting knives can be adjusted by relying on the screw rod and the two rotating rods inside the connecting piece, and the operation is simple.

DETAILED DESCRIPTION

[0023] The following will be combined with 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 of 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.

[0024] Example 1

[0025] like Figures 1 to 4 As shown, a specification adjustment mechanism of an automatic woven bag slitting machine includes a side panel 1. The side panel 1 is provided with two groups. A pillar 2 is fixedly connected between the two groups of side panels 1. An adjustment component 3 is provided at the outer end of the pillar 2. The adjustment component 3 includes a mounting plate 301 symmetrically slidably connected to the outer end of the pillar 2. A fixing claw 302 is fixedly connected to one side of the mounting plate 301. A rotating rod 303 is rotatably connected inside the fixing claw 302. A connecting piece 304 is rotatably connected between the two groups of rotating rods 303. A screw 305 is threadedly connected inside the connecting piece 304. A hot cutting component 4 is provided on the side of the mounting plate 301 away from the fixing claw 302. The purpose of this arrangement is that before slitting the woven bag, first rotate the screw 305 according to the required cutting width of the woven bag. As the screw 305 rotates, the connecting piece 304 drives the rotating rod 303 to rotate, so that the mounting plate 301 connected to the fixing claw 302 slides on the outer end of the pillar 2. The sliding distance of the two sets of mounting plates 301 remains consistent, so that the spacing adjustment of the two sets of hot cutting knives 402 is more accurate, reducing the error caused by slitting the woven bag. By rotating the screw 305, the two adjacent sets of hot cutting knives 402 can be adjusted, and the adjustment operation is simpler.

[0026] Preferably, the adjustment assembly 3 further includes a support rod 306 fixedly connected between the two sets of side plates 1, and the screw rod 305 is threadedly connected to the support rod 306. The purpose of this arrangement is that the support rod 306 has a limiting effect on the screw rod 305, and the screw rod 305, the two sets of rotating rods 303, and the support rod 306 are all arranged in a right triangle, thereby enhancing the stability of the mounting plate 301 during the sliding process.

[0027] Preferably, four groups of pillars 2 are provided and arranged in a square shape, and the support rods 306 are provided between the four groups of pillars 2, and the support rods 306 penetrate the mounting plate 301. The purpose of this arrangement is that the four groups of pillars 2 arranged in a square shape can prevent the mounting plate 301 from tilting during the sliding process, thereby causing the hot cutter 402 to tilt, affecting the slitting accuracy of the woven bag, and even causing the woven bag to be damaged. Since the support rods 306 penetrate the mounting plate 301, the mounting plate 301 is prevented from being obstructed during the adjustment process, causing the mounting plate 301 to tilt.

[0028] Preferably, the hot cutting assembly 4 includes a connecting frame 401 fixedly connected to the side end of the mounting plate 301, a hot cutting knife 402 is clamped inside the connecting frame 401, a clamping slot is provided inside the hot cutting knife 402, and a heating rod 403 is clamped inside the clamping slot. The purpose of this arrangement is that the arranged heating rod 403 transfers heat to the hot cutting knife 402, so that the hot cutting knife 402 makes the cut of the woven bag smoother.

[0029] Example 2

[0030] like Figures 1 to 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the bottom end of the side plate 1 is fixedly connected to a base frame 5, a support rod 6 is fixedly connected between the two groups of base frames 5, and a clamping plate 7 is slidably connected to the outer end of the support rod 6, and the position of the clamping plate 7 corresponds to the hot cutting knife 402. The purpose of this arrangement is that the support rod 6 between the two groups of base frames 5 and the clamping plate 7 at the outer end thereof play a supporting and stretching effect on the woven bag, so that the woven bag is in a straight state, thereby improving the accuracy of slitting the woven bag.

[0031] Preferably, a groove is provided inside the clamping plate 7, the cross-sections of the hot cutter 402 and the groove are both V-shaped, the support rod 6 and the hot cutter 402 are arranged vertically, and the support rod 6 is arranged at the center of the hot cutter 402. The purpose of this arrangement is that before slitting, the clamping plate 7 and the hot cutter 402 are first arranged in corresponding positions, and the V-shaped groove and the hot cutter 402 are convenient for cutting the woven bag.

[0032] Preferably, grooves are symmetrically provided at the top of the clamping plate 7, and rollers 8 are rotatably connected inside the grooves. The purpose of this arrangement is that the rollers 8 are arranged to facilitate the sliding of the woven bag on the top of the clamping plate 7, and to prevent the woven bag from being blocked during the slitting process.

[0033] Preferably, the internal thread of the clamping plate 7 is connected with a lock 9, and one end of the lock 9 is in conflict with the support rod 6. The purpose of this arrangement is that the lock 9 is convenient for fixing the clamping plate 7 to the outer end of the support rod 6, and it is also convenient to position the clamping plate 7 according to the position of the hot cutting knife 402.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
