Description

Technical Field

[0001] This utility model relates to the field of shearing device technology, and in particular to a shearing device for processing woven bags. Background Technology

[0002] With the continuous development of society and the continuous progress of technology, the technology related to shearing devices is also constantly improving. When processing the raw materials of woven bags, shearing devices are needed to cut the raw materials. Generally, a conveyor belt is used to transport the raw materials of woven bags to a specific position, and then a hot cutting knife is used to cut the raw materials of woven bags.

[0003] The cutting device currently in use has a hot cutting blade mounted on top that cannot be adjusted in angle. When it is necessary to cut the raw material of woven bags at an angle according to actual needs, so that the cutting line is set at an angle, different cutting devices need to be replaced for processing. The cutting device has great limitations in use and is not conducive to the cutting of raw materials of woven bags. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: the hot cutting blade installed on the top of the currently used shearing device cannot be adjusted in angle. When it is necessary to cut the raw material of woven bags at an angle according to actual use needs, so that the cutting line is set at an angle, different shearing devices need to be replaced for processing. The shearing device has great limitations in use and is not conducive to the cutting of raw materials of woven bags. Therefore, a shearing device for woven bag processing is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shearing device for woven bag processing includes a fixed frame and a conveyor belt. A bracket and a hydraulic cylinder are fixedly installed on the fixed frame. The driving end of the hydraulic cylinder is rotatably connected to a fixed rod with a T-shaped cross-section. A purification box is fixedly connected to the lower end of the fixed rod. A hot cutting knife is fixedly installed on the purification box.

[0007] A rotating rod with a T-shaped cross-section is rotatably mounted on the bracket. A fixed frame is fixedly connected to the upper end of the rotating rod. A slot is opened in the fixed frame. The fixed rod is connected to the rotating rod through a telescopic rod. Multiple telescopic components are symmetrically arranged inside the bracket. Each telescopic component includes a hollow cylinder fixedly mounted on the bracket. A compression block is connected inside the hollow cylinder through a first spring.

[0008] Preferably, a limit rod is slidably connected to the rotating rod, and an arc-shaped plate is fixedly connected to the fixed frame, with multiple slots evenly spaced on the arc-shaped plate.

[0009] Preferably, a second spring is sleeved on the limiting rod, one end of the second spring is fixedly connected to the limiting rod, and the other end of the second spring is fixedly connected to the rotating rod.

[0010] Preferably, the purification box has multiple air inlets and outlets, a fan is fixedly installed on the purification box, and an activated carbon filter layer is fixedly installed inside the purification box.

[0011] Preferably, L-shaped blocks are fixedly connected to both sides of the purification box, and a pressure plate with a T-shaped cross-section is slidably disposed on each L-shaped block. A reset spring is sleeved on each pressure plate, one end of the reset spring is fixedly connected to the pressure plate, and the other end of the reset spring is fixedly connected to the L-shaped block.

[0012] Preferably, a guide plate is fixedly provided on one side of the bracket, and the guide plate is inclined.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The rotating rod and the limiting rod rotate simultaneously. Under the transmission action of the telescopic rod, the fixed rod rotates relative to the drive end of the hydraulic cylinder. The hot cutting blade and the fixed frame rotate synchronously, which makes it easy to adjust the angle of the hot cutting blade according to actual use needs. When it is necessary to cut the raw material of woven bags at an angle according to actual use needs, so that the cutting line is set at an angle, there is no need to change different cutting devices for processing. The cutting device has fewer limitations in use and is beneficial to the cutting of woven bag raw materials. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-5 A shearing device for processing woven bags includes a fixed frame 1 and a conveyor belt 12. A bracket 10 and a hydraulic cylinder 4 are fixedly mounted on the fixed frame 1. A fixed rod 3 with a T-shaped cross-section is rotatably connected to the drive end of the hydraulic cylinder 4. A purification chamber 5 is fixedly connected to the lower end of the fixed rod 3. A hot cutting blade 2 is fixedly mounted on the purification chamber 5. A rotating rod 11 with a T-shaped cross-section is rotatably mounted on the bracket 10. A fixed frame 14 is fixedly connected to the upper end of the rotating rod 11. A slot is formed inside the fixed frame 14. The fixed rod 3 is connected to the rotating rod 11 via a telescopic rod 7. Multiple telescopic components are symmetrically arranged inside the support 10. Each telescopic component includes a hollow cylinder 8 fixedly installed on the support 10. An extrusion block 17 is connected inside the hollow cylinder 8 through a first spring 18. When the fixed frame 14 and the inner side wall of the support 10 are arranged parallel, each of the first springs 18 is in a compressed state. The multiple extrusion blocks 17 are respectively in contact with the two side surfaces of the fixed frame 14, but do not contact the middle surface of the two side surfaces of the fixed frame 14. The upper surface of the extrusion block 17 is 0.05 mm lower than the upper surface of the hollow cylinder 8, so as not to hinder the conveying of the woven bag raw materials.

[0024] A limiting rod 19 is slidably connected to the rotating rod 11. An arc-shaped plate 15 is fixedly connected to the fixed frame 1. Multiple slots are provided on the arc-shaped plate 15 at equal intervals. A second spring 20 is sleeved on the limiting rod 19. One end of the second spring 20 is fixedly connected to the limiting rod 19, and the other end of the second spring 20 is fixedly connected to the rotating rod 11. When the limiting rod 19 is pulled upward, the second spring 20 deforms. In the initial state, the lower end of the limiting rod 19 is inserted into the corresponding slot. After the limiting rod 19 moves upward, it will completely disengage from the slot. Then, the rotating rod 11 and the limiting rod 19 can rotate together.

[0025] The purification box 5 has multiple air inlets 16 and air outlets. A fan is fixedly installed on the purification box 5. An activated carbon filter layer (not shown) is fixedly installed inside the purification box 5. The hot cutting knife 2 can be heated by electricity. When the fan is powered on, the odor generated when the hot cutting knife 2 heats the woven bag raw material can be transported to the interior of the purification box 5 through the air inlets 16. The activated carbon filter layer inside the purification box 5 can deodorize the odor. The gas that has passed through the activated carbon filter layer and been deodorized can be discharged through the air outlet (not shown).

[0026] Both sides of the purification box 5 are fixedly connected to L-shaped blocks. Each L-shaped block is slidably equipped with a pressure plate 6 with a T-shaped cross-section. Each pressure plate 6 is fitted with a return spring 13. One end of the return spring 13 is fixedly connected to the pressure plate 6, and the other end of the return spring 13 is fixedly connected to the L-shaped block. During the downward movement of the hot cutting blade 2, the surfaces of the two pressure plates 6 will be in close contact with the surface of the woven bag raw material. Each pressure plate 6 and the corresponding L-shaped block will slide relative to each other, and the return spring 13 will deform. The two pressure plates 6 are distributed on both sides of the hot cutting blade 2, which can press the woven bag raw material to prevent the woven bag raw material from shifting during the subsequent hot cutting process. A guide plate 9 is fixedly installed on one side of the bracket 10. The guide plate 9 is inclined. The cut woven bag raw material can slide down the surface of the guide plate 9 into the collection frame (not shown) for collection.

[0027] In this utility model, during use, the limiting rod 19 is first pulled upwards, causing the second spring 20 to deform. Initially, the lower end of the limiting rod 19 is inserted into the corresponding slot. After the limiting rod 19 moves upwards, it completely disengages from the slot. Then, the rotating rod 11 and the limiting rod 19 rotate simultaneously. Since one end of the telescopic rod 7 is fixedly connected to the fixed rod 3 and the other end is fixedly connected to the rotating rod 11, under the transmission action of the telescopic rod 7, the fixed rod 3 rotates relative to the driving end of the hydraulic cylinder 4. The fixed frame 14... During the rotation, the two sides of the fixed frame 14 move against the arc surfaces of some of the extrusion blocks 17, thereby causing some of the extrusion blocks 17 to retract into the corresponding hollow cylinder 8. Since one end of the first spring 18 is fixedly connected to the extrusion block 17 and the other end is fixedly connected to the inner wall of the hollow cylinder 8, the first spring 18 deforms. Under the elastic force of the first spring 18, some of the extrusion blocks 17 will extend to the outside of the hollow cylinder 8, so that the arc surfaces of each extrusion block 17 are always in contact with the two sides of the fixed frame 14.

[0028] After the hot cutting blade 2 and the fixed frame 14 rotate synchronously, the external force applied to the limiting rod 19 is removed. Under the elastic force of the second spring 20, the lower end of the limiting rod 19 will be inserted into the corresponding slot. During the subsequent process of the hydraulic cylinder 4 driving the fixed rod 3 to move down, the hot cutting blade 2 can cut the woven bag raw material located directly above the fixed frame 14. Part of the hot cutting blade 2 extends into the slot of the fixed frame 14. The tilt angle of the hot cutting blade 2 can be adjusted according to the actual use needs. When it is necessary to tilt the woven bag raw material according to the actual use needs, so that the cutting line is tilted, it is not necessary to change different cutting devices for processing. The limitations of the cutting device are small, which is beneficial to the cutting of woven bag raw materials.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
