Technical Field
[0001] This utility model relates to the field of woven bag production technology, specifically a woven bag production machine that facilitates the replacement of yarn spools. Background Technology
[0002] Woven bags are used in various industries, serving the purpose of convenient transportation and temporary storage. The production of woven bags requires a weaving machine to weave yarn into bags. Weaving machines are efficient, adaptable, and energy-saving. However, during operation, after a single roller of yarn is used up, a new yarn roller needs to be replaced. Failure to replace it in time will affect the subsequent operation of the machine. To overcome this defect, prior art 1 (Chinese patent application No. 202021107980.2, filed on 2020-06-15) describes a cable braiding machine, which features convenient operation during operation. The device allows operators to clearly observe the yarn spools on the reels, enabling them to quickly install or replace yarn spools on the braiding machine. Existing technology 2 (Chinese patent application No. 201921511102.4, filed on 2019-09-11) describes a textile braiding machine with a quick-change yarn spool. During use, the yarn spool is supported between two sets of support plates by two extendable movable support shafts on both sides. Pulling the movable support shafts outwards allows for quick yarn spool replacement, making it convenient and efficient. In this invention, the end of the movable support shaft and the shaft hole on the yarn spool are connected by ball bearings, ensuring smooth rolling and preventing jamming.
[0003] During the replacement of the wire winding roller, if the roller itself has many burrs, the replacement may be stuck. The device in the above application does not have a structure to assist in disassembly during the replacement of the wire winding roller, which will cause the replacement process to be unsmooth and reduce the work efficiency of the workers. Utility Model Content
[0004] The purpose of this invention is to provide a weaving machine for woven bag production that facilitates the replacement of yarn spools, thereby solving the problem mentioned in the background art that the lack of an auxiliary disassembly structure during the replacement of yarn spools leads to an unsmooth replacement process for workers and reduces their work efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a weaving machine for producing woven bags that facilitates the replacement of yarn spools, comprising a machine body, a support rod on the upper surface of the machine body, and a placement rod fixedly connected at equal angles to the surface of the support rod, and a yarn spool roller engaged with the surface of the placement rod; a fixing plate fixedly connected to the surface of the placement rod, and a positioning groove provided on the surface of the placement rod, and a movable plate connected to the surface of the placement rod via a engaging assembly; a push rod slidably disposed inside the placement rod.
[0006] Preferably, a positioning block is fixedly connected to the inner wall of the movable plate, and the positioning blocks are symmetrically distributed on both sides of the movable plate, and the positioning blocks correspond one-to-one with the positioning grooves.
[0007] Preferably, the engaging assembly includes a locking block slidably disposed inside the placement rod, and the surface of the locking block is fixedly connected with a protrusion, and the interior of the placement rod is provided with a groove corresponding to the locking block.
[0008] Preferably, the upper surface of the card block is inclined, and a first spring is fixedly connected to the lower surface of the card block, and the other side of the first spring is fixedly connected to the inner wall of the placement rod.
[0009] Preferably, a lever is fixedly connected to the outer side of the card block, and the lever is located outside the placement rod, and the card blocks are symmetrically distributed on both sides of the placement rod.
[0010] Preferably, the surface of the push rod is in contact with the inner wall of the placement rod.
[0011] Preferably, a second spring is fixedly connected to the surface of the push rod, and the other side of the second spring is fixedly connected to the inner wall of the placement rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are: this woven bag production machine, which facilitates the replacement of yarn spools, adopts a novel structural design, the specific details of which are as follows:
[0013] (1) In the process of connecting the spools of the woven bag production machine, the push rod is pushed by the movable plate during the connection of the spools, and then the push rod moves in the direction of squeezing the second spring. That is, during the normal use of the spools, the second spring is in a compressed and stored state. When the spools need to be disassembled, the second spring and the push rod play an auxiliary pushing role, and the spools will not jam, resulting in high work efficiency.
[0014] Furthermore, the push rods are distributed on both sides of the placement rod, which optimizes the effect of pushing and assisting in material feeding and improves work efficiency.
[0015] (2) When a new spool roller is needed to be connected to the woven bag production machine that facilitates the replacement of spools, the new spool roller is placed on the placement rod and connected to the movable plate. At this time, the positioning block on the inner wall of the movable plate is inserted into the positioning groove. During this process, the locking block is pushed and moves in the direction of squeezing the first spring. After the positioning block contacts the bottom of the positioning groove, the locking block returns to its original position under the action of the first spring. At this time, the locking block holds the positioning block, and the movable plate holds the spool roller, so that the new spool roller can be used normally.
[0016] Furthermore, during the movement of the card block, the protrusions and grooves limit the movement distance of the card block, ensuring the stability of the card block's operation.
[0017] (3) When the woven bag production machine that facilitates the replacement of the spool needs to remove the spool, the lever is pulled and the lever will drive the locking block to move into the placement rod. When the locking block does not contact the positioning block, the push rod moves outward under the action of the second spring, that is, the lever plays the role of quickly contacting the locking state.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] This utility model provides the following technical solution: a weaving machine for producing woven bags that facilitates the replacement of yarn spools.
[0029] Example 1: Using the locking block 9 and the first spring 10, the wire winding roller 4 can be quickly aligned with the placement rod 3, as shown below. Figures 1-8 As shown, the device includes a body 1, a support rod 2 on the upper surface of the body 1, a placement rod 3 fixedly connected to the surface of the support rod 2, and a wire winding roller 4 engaged with the surface of the placement rod 3; a fixing plate 5 fixedly connected to the surface of the placement rod 3, a positioning groove 8 formed on the surface of the placement rod 3, and a movable plate 6 connected to the surface of the placement rod 3 via a locking assembly; positioning blocks 7 fixedly connected to the inner wall of the movable plate 6, and the positioning blocks 7 are symmetrically distributed on both sides of the movable plate 6, with each positioning block 7 corresponding to a positioning groove 8.
[0030] The locking assembly includes a locking block 9 that is slidably disposed inside the placement rod 3, and a protrusion 12 is fixedly connected to the surface of the locking block 9. A groove 13 corresponding to the locking block 9 is opened inside the placement rod 3. The upper surface of the locking block 9 is inclined, and a first spring 10 is fixedly connected to the lower surface of the locking block 9. The other side of the first spring 10 is fixedly connected to the inner wall of the placement rod 3.
[0031] When it is necessary to connect the wire winding roller 4, the wire winding roller 4 is placed on the placement rod 3, and then connected to the movable plate 6. At this time, the positioning block 7 on the inner wall of the movable plate 6 is inserted into the positioning groove 8. During this process, the locking block 9 is pushed by the positioning block 7. At this time, the locking block 9 moves in the direction of squeezing the first spring 10. After the positioning block 7 contacts the bottom of the positioning groove 8, the locking block 9 returns to its original position under the action of the first spring 10. At this time, the locking block 9 holds the positioning block 7, and then the movable plate 6 and the fixed plate 5 cooperate to hold the wire winding roller 4, so that the wire winding roller 4 can be used normally (e.g. Figure 6 As shown), during the movement of the locking block 9, the protrusion 12 and the groove 13 limit the movement distance of the locking block 9, ensuring the stability of the locking block 9's operation (as shown). Figure 8 (As shown).
[0032] Example 2: Unlike Example 1, the movable plate 6 can be quickly removed using the lever 11, as shown below. Figure 6 and Figure 7 As shown, a lever 11 is fixedly connected to the outside of the locking block 9, and the lever 11 is located outside the placement rod 3, and the locking blocks 9 are symmetrically distributed on both sides of the placement rod 3.
[0033] After the machine body 1 has been working for a long time, when it is necessary to remove the wire winding roller 4, pull the lever 11. The lever 11 will drive the locking block 9 to move into the placement rod 3, so that the locking block 9 does not contact the positioning block 7. At this time, the positioning block 7 can slide again in the positioning groove 8, so that the movable plate 6 no longer presses against the wire winding roller 4, and finally the wire winding roller 4 can be removed.
[0034] Example 3: Unlike Example 2, the push rod 14 and the second spring 15 assist in disassembly, preventing jamming during the replacement of the winding roller 4. Figure 6 and Figure 7 As shown, a push rod 14 is slidably disposed inside the placement rod 3. The surface of the push rod 14 is in contact with the inner wall of the placement rod 3. A second spring 15 is fixedly connected to the surface of the push rod 14, and the other side of the second spring 15 is fixedly connected to the inner wall of the placement rod 3.
[0035] During the connection process of the wire winding roller 4, the push rod 14 is pushed by the movable plate 6, and then the push rod 14 moves in the direction of squeezing the second spring 15. That is, during the normal use of the wire winding roller 4, the second spring 15 is in a compressed and stored state. When it is necessary to disassemble the wire winding roller 4, the second spring 15 and the push rod 14 play an auxiliary pushing role, and the wire winding roller 4 will not get stuck. The working efficiency is high. At the same time, the push rod 14 is distributed on both sides of the placement rod 3, which optimizes the pushing and assisting material feeding effect and improves the working efficiency.
[0036] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
