Technical Field

[0001] This utility model belongs to the field of woven bag production and processing, specifically, it relates to a woven bag heat cutting machine roll pressing device. Background Technology

[0002] Hot cutting of woven bags is a process that uses high-temperature blades to melt and cut plastic woven bags. It is mainly used to solve problems such as rough edges and stringing caused by traditional cold cutting, and to improve the flatness and sealing of the cut surface.

[0003] When heat-cutting woven bags, the rolled-up woven bags need to be unrolled and then heat-cut. However, traditional woven bags do not have the effect of preventing loosening when unrolling. This means that if the unrolling speed of the woven bag is faster than the rolling speed, the rolled woven bag is very likely to become loose and tangled, affecting the quality and efficiency of heat cutting. Therefore, there is an urgent need for a pressing device that can prevent the unrolling of woven bags from becoming loose.

[0028] like Figure 1 and Figure 2 As shown, a woven bag heat-cutting machine roll pressing device includes: a base frame 20, the base frame 20 is a rectangular frame, and a woven bag roll 21 is installed on the top of the front wall of the base frame 20. This is existing technology, so it will not be described in detail here.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a pressure guide structure is installed on the top of the base frame 20 to press and guide the woven bag roll 21. The pressure guide structure includes: a fixed rail 30, a slide groove 31, a slider 33, a pressure block 37, a connecting rod 40, and a limiting block 41. The fixed rail 30 is located at the top of the front wall of the base frame 20. The slide groove 31 is opened at the bottom of the fixed rail 30. The sliders 33 are symmetrically arranged in the slide groove 31. The pressure block 37 is located below each slider 33. The connecting rod 40 is fixedly connected to the outer wall of each pressure block 37. The limiting block 41 is fixedly connected to the side wall of the symmetrical connecting rods 40 facing each other. The bottom of the pressure block 37 can press the top of the woven bag roll 21.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixed rail 30 is a rectangular box, the slide groove 31 is a T-shaped groove that can accommodate the sliding of the slider 33, the slider 33 is a T-shaped block, the pressure block 37 is an L-shaped plate, the connecting rod 40 is an arc-shaped rod, and the limiting block 41 is a C-shaped block. The pressure guide structure also includes a locking groove 32, a spring groove 34, a spring 35, a spring block 36, a hidden groove 38, and a locking post 39. The locking groove 32 is formed through the top of the fixed rail 30, the spring groove 34 is formed at the bottom of each slider 33, the spring 35 is fixedly connected to the wall of the slider 33 in each spring groove 34, the spring block 36 is slidably connected in each spring groove 34, the hidden groove 38 is formed at the bottom of each pressure block 37, and the locking post 39 is slidably connected in each hidden groove 38. The locking groove 32 is a circular groove, and multiple identical locking grooves 32 are linearly arrayed on the top of the fixed rail 30. The spring groove 34 is an inverted U-shaped groove that can accommodate the sliding of the spring block 36. The bottom of the spring block 36 can be fixedly connected to the top of the pressure block 37, the bottom of the spring 35 can abut against the top of the spring block 36, the locking pin 39 is composed of a cylinder and a bottom disc, the hidden groove 38 can be adapted to the size of the disc of the locking pin 39, the hidden groove 38, the spring block 36 and the slider 33 are provided with a circular hole adapted to the size of the cylinder of the locking pin 39, the diameter of the circular hole is the same as the locking groove 32, the side wall of the spring block 36 is provided with a rectangular groove, and rectangular blocks are symmetrically fixedly connected in the rectangular groove of the wall of the spring block 36. The arc surface of the cylinder of the locking pin 39 is symmetrically provided with a rectangular groove that can slide and engage with the rectangular block of the wall of the spring block 36. The top of the front wall of the base frame 20 is symmetrically fixedly connected with a winding frame 22, the winding frame 22 is Y-shaped, and the rear wall of each winding frame 22 is fixedly connected with a high frame 24, the high frame 24 is C-shaped. The top of the front wall of the symmetrical high frame 24 can be fixedly connected to both sides of the fixed rail 30.

[0031] In practical use, first, align the bottom ends of the woven bag roll 21 to be unwound with the top opening of the symmetrical unwinding frame 22 and insert it. Then, move the pressure block 37 to the top arc edge of the corresponding woven bag roll 21. When the pressure block 37 is moved, the top of the locking pin 39 will not be inserted into the locking groove 32. Then, when the pressure block 37 is moved, it will drive the spring block 36, spring 35, slider 33 and locking pin 39 to slide synchronously. The connecting rod 40 and the limiting block 41 will also move synchronously with the pressure block 37. After the bottom opening of the pressure block 37 is in contact with the top arc surface of the woven bag roll 21, the bottom of the locking pin 39 will move upward due to the contact of the woven bag roll 21. The locking pin 39 will move upward along the inside of the round hole. The top of the locking pin 39 will pass directly through the top of the slider 33 and be inserted into the corresponding locking groove 32 to lock the position of the slider 33. When the slider 33 is locked, it will drive the spring block 36. The pressure block 37, connecting rod 40 and limiting block 41 are locked synchronously, while the spring block 36 will drive the pressure block 37, connecting rod 40 and limiting block 41 to automatically adapt to the size of the top of the woven bag roll 21 along the lower part of the slider 33. At this time, the woven bag roll 21 is extended and pulled open, and then its end passes through the opening of the symmetrical limiting block 41. Then it is pulled open and extended to the hot cutting machine for hot cutting. As the woven bag is unwound, the bottom of the pressure block 37 will always press the woven bag roll 21, and the two sides of the unfolded woven bag will always slide through the opening of the symmetrical limiting block 41. After the hot cutting is completed, the woven bag that is wound up at the top of the unwinding frame 22 will also be unwound synchronously. At this time, the winding roller can be removed from the top of the unwinding frame 22 and replaced with the woven bag roll 21 that needs to be hot cut in the next batch. After the winding roller at the top of the unwinding frame 22 is removed, the locking pin 39 will slide down again and separate from the locking groove 32. At this time, the position of the slider 33 will be unlocked again.

[0032] In summary, by setting up a pressure guide structure to synchronously press and guide the woven bag, the woven bag will not be loose during unwinding and hot cutting. Furthermore, the limiting block 41 will guide and limit the unfolded woven bag to prevent displacement from affecting the hot cutting quality.

[0033] like Figure 1 and Figure 2 As shown, each unwinding rack 22 has a rotating block 23 symmetrically rotatably connected in the top opening. The rotating block 23 is round, and the arc surface of the rotating block 23 can contact the bottom sides of the woven bag roll 21.

[0034] In practical use, when the woven bag roll 21 is unrolled and rolled, the rotating block 23 on the wall of the unrolling frame 22 will rotate along with the rolling woven bag roll 21.

[0035] In summary, by setting the turn block 23, the friction of the woven bag roll 21 during unwinding can be effectively reduced, which can effectively improve the smoothness of unwinding and prevent the woven bag roll 21 from being damaged during unwinding.

[0036] Working principle: First, align the bottom ends of the woven bag roll 21 to be unwound with the top opening of the symmetrical unwinding frame 22 and insert it. Then, move the pressure block 37 to the top arc edge of the corresponding woven bag roll 21. When the pressure block 37 is moved, the top of the locking pin 39 will not be inserted into the locking groove 32. Then, when the pressure block 37 is moved, it will drive the spring block 36, spring 35, slider 33 and locking pin 39 to slide synchronously. The connecting rod 40 and the limiting block 41 will also move synchronously with the pressure block 37. After the bottom opening of the pressure block 37 is in contact with the top arc surface of the woven bag roll 21, the bottom of the locking pin 39 will be affected by the woven bag roll 21. The slider 33 moves upward upon contact with the contact pin 1, and the locking pin 39 moves upward along the inside of the circular hole. The top of the locking pin 39 passes directly through the top of the slider 33 and is inserted into the corresponding locking groove 32 to lock the position of the slider 33. When the slider 33 is locked, it drives the spring block 36, the pressure block 37, the connecting rod 40 and the limiting block 41 to lock synchronously. The spring block 36 drives the pressure block 37, the connecting rod 40 and the limiting block 41 to automatically adapt to the size of the top of the woven bag roll 21 below the slider 33. At this time, the woven bag roll 21 is extended and pulled open, and then its end passes through the opening of the symmetrical limiting block 41, and then it is pulled open and extended to the hot cutting machine for hot cutting.
