Description

Technical Field

[0001] The utility model relates to the technical field of chain-link fence winding devices, in particular to a chain-link fence knitting and forming winding device. Background Art

[0002] The chain-link fence is woven from metal wires (such as PVC wires, stainless steel wires, high-quality low-carbon steel wires, galvanized wires, iron wires, etc.) through a specific process. The mesh holes are uniform, the mesh surface is flat, the weaving is simple and beautiful. According to different weaving methods, the chain-link fence can be divided into two types: folded-edge shrinkage handle and twisted-edge lock handle. In addition, the chain-link fence can also be surface-treated as required, such as electro-galvanizing, hot-dip galvanizing, plastic coating (PVC, PE plastic coating), dip coating, spray coating, etc., to enhance its corrosion resistance and service life. After the chain-link fence is woven, it needs to be wound into a cylindrical shape by a winding device to facilitate subsequent packaging and transportation work.

[0003] The existing winding devices usually use a rotating cylindrical structure to wind the mesh around the surface to complete the winding work. However, since the chain-link fence is made of metal material, it has a certain hardness and a small friction coefficient with the surface of the cylinder. Therefore, in the initial stage of winding, it is very easy for the mesh to slip between the mesh body and the cylinder, resulting in the difficulty of the winding work. At this time, manual assistance is required for the winding work until a certain number of turns of the wire mesh are wound on the surface of the cylinder. In order to avoid the slipping between the mesh body and the cylinder, some winding mechanisms also adopt the method of using a ratchet or setting a claw on the cylinder to play a role of hooking the mesh body to prevent it from sliding during winding. However, this method makes it more inconvenient to remove the wound mesh cylinder after winding. Therefore, in view of the above problems, a chain-link fence knitting and forming winding device is proposed. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a chain-link fence knitting and forming winding device. The chain-link fence winding device can drive the retractable winding cylinder with a toothed wheel to rotate by a lapping drive mechanism to complete the winding work of the chain-link fence. During winding, the mesh clamping rod fully extends and can hook the mesh body when rotating with the outer sleeve, so that the mesh body is wound on the outer sleeve, avoiding the relative sliding between the chain-link fence and the outer sleeve and affecting the winding efficiency. When the winding is completed, rotate the rotating shaft, and the mesh clamping rod retracts completely into the fitting groove under the pulling force of the hinge seat, which is convenient for workers to remove the wound cylindrical mesh body, solving the technical problems in the prior art that the mesh body is prone to slip between the mesh body and the cylinder during winding, affecting the winding efficiency, and the method of using a ratchet or setting a claw on the cylinder is more inconvenient when removing the wound mesh cylinder.

[0005] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0006] A wire mesh knitting and forming winding device includes a retractable toothed winding drum for winding the wire mesh, and a support base provided with a lapped driving mechanism for driving the retractable toothed winding drum to rotate. Among them, the retractable toothed winding drum includes an outer sleeve and a middle rotating shaft therein. A number of groups of hinge seats are provided on the middle rotating shaft, and a wire-catching rod is rotatably connected to the hinge seat. A number of groups of corresponding fitting grooves are opened on the outer sleeve, and the wire-catching rod is slidably arranged in the fitting grooves.

[0007] Through the above structural form, the lapped driving mechanism drives the retractable toothed winding drum to rotate to complete the winding work of the wire mesh. And during winding, the wire-catching rod fully extends, and can hook the mesh body when following the rotation of the outer sleeve to make it wind around the outer sleeve, avoiding the relative sliding between the wire mesh and the outer sleeve and affecting the winding efficiency. When the winding is completed, the middle rotating shaft is rotated, and the wire-catching rod retracts completely into the fitting groove under the pulling force of the hinge seat, so that there are no protrusions on the surface of the outer sleeve, which is convenient for workers to quickly and conveniently remove the wound cylindrical mesh body.

[0008] In a possible implementation manner, the lapped driving mechanism includes paired friction driving wheels and a friction sleeve. Among them, the friction driving wheels are rotatably arranged on the support base and are driven by a driving motor, and the friction sleeve is fixedly sleeved on both sides of the outer sleeve.

[0009] Through the above structural form, the retractable toothed winding drum is integrally lapped on the paired friction driving wheels. When the driving motor works to drive the friction driving wheels to rotate, the retractable toothed winding drum can be driven to rotate through the friction effect. In particular, this method is convenient for removing the retractable toothed winding drum at any time, and then removing the wound mesh cylinder.

[0010] In a possible implementation manner, a curved groove is provided in the middle of the surface of the friction sleeve, and a curved convex that fits the curved groove is fixedly arranged on the surface of the friction driving wheel.

[0011] Through the above structural form, the concave-convex structure can play an auxiliary positioning role, avoiding a large deviation in the position where the retractable toothed winding drum is installed, which affects the transmission efficiency. In addition, the concave-convex structure can increase the contact area between the friction sleeve and the friction driving wheel, thereby increasing the friction force between the two, making it not easy to affect the transmission efficiency due to relative rotation.

[0012] In a possible implementation manner, bearing brackets are fixedly arranged on the inner sides of both ends of the outer sleeve, and mounting bearings are fixedly installed in the bearing brackets. The two ends of the middle rotating shaft are respectively fixedly connected to the inner rings of the corresponding mounting bearings.

[0013] Through the above structural form, the middle rotating shaft can be fixedly installed on the central axis of the outer sleeve without affecting its rotation.

[0014] In a possible implementation, rotation locking mechanisms are provided at both ends of the retractable take-up reel of the card teeth. The rotation locking mechanism includes a mating shaft fixedly connected to the middle rotating shaft. The end of the mating shaft extends out of the outer sleeve, and a clamping member is slidably sleeved thereon. Two groups of slots are formed at the end of the outer sleeve, and a plug shaft that mates with the slots is fixedly connected to the clamping member.

[0015] With the above structural form, when the plug shaft is inserted into the slot, since the mating shaft and the clamping member cannot rotate relative to each other, the middle rotating shaft and the outer sleeve cannot rotate relative to each other, thereby realizing the connection between the two and preventing the middle rotating shaft from rotating during winding, which may cause the card net rod to retract and become ineffective.

[0016] In a possible implementation, when the plug shaft is inserted into one group of slots, the card net rod is completely in the extended state, and when the plug shaft is inserted into the other group of slots, the card net rod retracts into the mating groove.

[0017] With the above structural form, two groups of slots can be used to fix the two relative rotational positions of the middle rotating shaft, ensuring that the card net rod only has two states of complete extension and complete retraction during use, corresponding to meeting two different requirements.

[0018] In a possible implementation, an installation piece is fixedly arranged on the mating shaft, and a tension spring sleeved outside the mating shaft is fixedly connected to the installation piece. The end of the tension spring away from the installation piece is fixedly connected to the clamping member.

[0019] With the above structural form, the tension spring can apply a pulling force to make the clamping member fit against the end of the outer sleeve, and the two can always remain in close contact without the influence of external forces, avoiding the situation where the plug shaft slips out of the slot due to the outward sliding of the clamping member during use, resulting in the card net rod losing restraint and sliding freely.

[0020] In a possible implementation, the support base includes a bottom plate, a group of support plates are fixedly arranged on the bottom plate, and a motor bracket is fixedly arranged on the outer side surface of the support plate.

[0021] With the above structural form, a necessary structural basis is provided for the installation and operation of the lap joint drive mechanism.

[0022] In summary, the utility model includes the following beneficial technical effects:

[0023] The toothed retractable take-up reel is driven by a lapped driving mechanism to rotate, completing the winding of the diamond mesh. During the winding process, the net clamping rod fully extends and can hook the net body when following the outer sleeve to rotate, causing the net body to wind around the outer sleeve, avoiding relative sliding between the diamond mesh and the outer sleeve and affecting the winding efficiency. After the winding is completed, the middle rotating shaft is rotated, and under the pulling force of the hinge seat, the net clamping rod retracts completely and slides into the fitting groove, making the surface of the outer sleeve without protrusions, which is convenient for workers to quickly and easily remove the wound cylindrical net body.

Detailed Embodiments

[0031] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0032] As Figure 1 - Figure 3As shown in the figure, a jacquard net knitting and forming winding device provided in this embodiment includes a card tooth retractable winding drum 1 for winding the jacquard net, and a support base 2 provided with a lapping drive mechanism 3 for driving the card tooth retractable winding drum 1 to rotate. Among them, the card tooth retractable winding drum 1 includes an outer sleeve 11 and a middle rotating shaft 12 therein. A plurality of groups of hinge seats 13 are provided on the middle rotating shaft 12, and a net clamping rod 14 is rotatably connected to the hinge seat 13. A plurality of groups of corresponding mating grooves 15 are opened on the outer sleeve 11, and the net clamping rod 14 is slidably arranged in the mating groove 15. Through the above structural form, the lapping drive mechanism 3 drives the card tooth retractable winding drum 1 to rotate to complete the winding work of the jacquard net. And during winding, the net clamping rod 14 fully extends out and can hook the net body when following the rotation of the outer sleeve 11 so that it winds around the outer sleeve 11, avoiding relative sliding between the jacquard net and the outer sleeve 11 and affecting the winding efficiency. When the winding is completed, the middle rotating shaft 12 is rotated, and the net clamping rod 14 retracts completely and slides into the mating groove 15 under the pulling force of the hinge seat 13, so that there are no protrusions on the surface of the outer sleeve 11, which is convenient for workers to quickly and conveniently remove the wound cylindrical net body.

[0033] As Figure 4 shown, the lapping drive mechanism 3 includes a pair of friction drive wheels 31 and a friction sleeve 32. Among them, the friction drive wheel 31 is rotatably arranged on the support base 2 and is driven by a drive motor 33. The friction sleeve 32 is fixedly sleeved on both sides of the outer sleeve 11. Through the above structural form, the card tooth retractable winding drum 1 is integrally lapped on the pair of friction drive wheels 31. When the drive motor 33 works to drive the friction drive wheel 31 to rotate, it can drive the card tooth retractable winding drum 1 to rotate through frictional action. In particular, this method is convenient for removing the card tooth retractable winding drum 1 at any time, and then removing the wound net cylinder.

[0034] Among them, a curved groove is arranged in the middle on the surface of the friction sleeve 32, and a curved convex that fits the curved groove is fixedly arranged on the surface of the friction drive wheel 31. Through the above structural form, the concave-convex structure can play an auxiliary positioning role, avoiding large deviation in the position where the card tooth retractable winding drum 1 is installed and affecting the transmission efficiency. In addition, the concave-convex structure can increase the contact area between the friction sleeve 32 and the friction drive wheel 31, thereby improving the friction force between the two and making it not easy to affect the transmission efficiency due to relative rotation.

[0035] As Figure 5 shown, bearing brackets 161 are fixedly arranged on the inner sides of both ends of the outer sleeve 11, and mounting bearings 16 are fixedly installed in the bearing brackets 161. The two ends of the middle rotating shaft 12 are respectively fixedly connected to the inner rings of the corresponding mounting bearings 16. Through the above structural form, the middle rotating shaft 12 can be fixedly installed on the central axis of the outer sleeve 11 without affecting its rotation.

[0036] As shown Figure 5 in the figure, rotation locking mechanisms 4 are provided at both ends of the retractable winding drum 1 with engaging teeth. The rotation locking mechanism 4 includes a mating shaft 41 fixedly connected to the middle rotating shaft 12. The end of the mating shaft 41 extends out of the outer sleeve 11, and a clamping member 42 is slidably sleeved thereon. Two groups of slots 44 are formed at the end of the outer sleeve 11. A plug shaft 43 that cooperates with the slots 44 is fixedly connected to the clamping member 42. With the above structural form, when the plug shaft 43 is inserted into the slots 44, since the mating shaft 41 and the clamping member 42 cannot rotate relative to each other, the middle rotating shaft 12 and the outer sleeve 11 cannot rotate relative to each other, thereby realizing the connection between the two and preventing the middle rotating shaft 12 from rotating during winding, which may cause the net clamping rod 14 to retract and become ineffective.

[0037] Among them, when the plug shaft 43 is inserted into one group of slots 44, the net clamping rod 14 is completely in the extended state. When the plug shaft 43 is inserted into the other group of slots 44, the net clamping rod 14 retracts into the mating groove 15. With the above structural form, the two groups of slots 44 can be used to fix the two relative rotation positions of the middle rotating shaft 12, ensuring that the net clamping rod 14 only has two states of complete extension and complete retraction during use, corresponding to meeting two different requirements.

[0038] In addition, an installation piece 45 is fixedly arranged on the mating shaft 41, and a tension spring 46 sleeved outside the mating shaft 41 is fixedly connected to the installation piece 45. The end of the tension spring 46 away from the installation piece 45 is fixedly connected to the clamping member 42. With the above structural form, the tension spring 46 can apply a pulling force to make the clamping member 42 fit against the end of the outer sleeve 11, and the two can always remain in close contact without the influence of external forces, preventing the situation where the plug shaft 43 disengages from the slots 44 due to the outward sliding of the clamping member 42 during use, resulting in the net clamping rod 14 losing restraint and freely sliding.

[0039] As shown Figure 4 in the figure, the support base 2 includes a bottom plate 21, a group of support plates 22 are fixedly arranged on the bottom plate 21, and a motor bracket 23 is fixedly arranged on the outer side surface of the support plate 22. With the above structural form, it provides a necessary structural basis for the installation and operation of the lapping drive mechanism 3.

[0040] The working principle and process of the present utility model:

[0041] The toothed retractable winding drum 1 is driven to rotate by the lapped driving mechanism 3 to complete the winding of the diamond mesh. During winding, the net clamping rod 14 fully extends and can hook the net body when rotating with the outer sleeve 11, causing the net to wind around the outer sleeve 11, preventing relative sliding between the diamond mesh and the outer sleeve 11 and affecting the winding efficiency. After winding is completed, the middle rotating shaft 12 is rotated, and the net clamping rod 14 retracts completely into the fitting groove 15 under the pulling force of the hinge seat 13, making the surface of the outer sleeve 11 free of protrusions, which facilitates workers to quickly and conveniently remove the wound cylindrical net body.

[0042] The toothed retractable winding drum 1 is integrally lapped on a pair of friction driving wheels 31. When the driving motor 33 operates to drive the friction driving wheels 31 to rotate, the toothed retractable winding drum 1 can be driven to rotate through frictional action. In particular, this method facilitates the removal of the toothed retractable winding drum 1 at any time, and then the wound net cylinder can be removed.

[0043] In addition, when the insertion shaft 43 is inserted into the slot 44, since the fitting shaft 41 and the clamping member 42 cannot rotate relative to each other, the middle rotating shaft 12 and the outer sleeve 11 cannot rotate relative to each other, thus realizing the connection between the two. This prevents the middle rotating shaft 12 from rotating during winding, causing the net clamping rod 14 to retract and become ineffective. Two sets of slots 44 can fix the two relative rotating positions of the middle rotating shaft 12, ensuring that the net clamping rod 14 only has two states: fully extended and fully retracted, corresponding to meeting two different requirements.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
